Outcome and preferences in male–to–female subjects with gender dysphoria: Experience from Eastern India p. 21
Anirban Majumder, Debmalya Sanyal
Context: Gender dysphoria (GD) is an increasingly recognized medical condition in India, and little scientific data on treatment outcomes are available. Aims: Our objective is to study the therapeutic options including psychotherapy, hormone, and surgical treatments used for alleviating GD in male–to–female (MTF) transgender subjects in Eastern India. Subjects and Methods: This is a retrospective study of treatment preferences and outcome in 55 MTF transgender subjects who were presented to the endocrine clinic. Statistical Analysis Used: Descriptive statistical analysis is carried out in the present study, and Microsoft Word and Excel are used to generate graphs and tables. Results: The mean follow-up was 1.9 years and 14 subjects (25.5%) were lost to follow-up after a single or 2–3 contact sessions. Rest 41 subjects (74.5%) desiring treatment had regular counseling and medical monitoring. All 41 subjects were dressing to present herself as female and all of them were receiving cross-sex hormone therapy either estrogen only (68%), or drospirenone in combination with estrogen (12%) or gonadotropin-releasing hormone agonist (GnRH) in combination with estrogens (19.5%). Most of the subjects preferred estrogen therapy as it was most affordable and only a small number of subjects preferred drospirenone or GnRH agonist because of cost and availability. 23.6% subjects underwent esthetic breast augmentation surgery and 25.5% underwent orchiectomy and/or vaginoplasty. Three subjects presented with prior breast augmentation surgery and nine subjects presented with prior orchiectomy without vaginoplasty, depicting a high prevalence of poorly supervised surgeries. Conclusions: Standards of care documents provide clinical guidance for health professionals about the optimal management of transsexual people. The lack of information among health professionals about proper and protocolwise management leads to suboptimal physical, social, and sexual results.

Effects of thyroid status on glycated hemoglobin p. 26
Rana Bhattacharjee, Anubhav Thukral, Partha Pratim Chakraborty, Ajitesh Roy, Soumik Goswami, Sujoy Ghosh, Pradip Mukhopadhyay, Satinath Mukhopadhyay, Subhankar Chowdhury
Introduction: Glycated hemoglobin (HbA1c) can be altered in different conditions. We hypothesize that HbA1c levels may change due to altered thyroid status, possibly due to changes in red blood cell (RBC) turnover. Objectives: The objective of this study was to determine the effects of altered thyroid status on HbA1c levels in individuals without diabetes, with overt hyper- and hypo-thyroidism, and if present, whether such changes in HbA1c are reversed after achieving euthyroid state. Methods: Euglycemic individuals with overt hypo- or hyper-thyroidism were selected. Age- and sex-matched controls were recruited. Baseline HbA1c and reticulocyte counts (for estimation of RBC turnover) were estimated in all the patients and compared. Thereafter, stable euthyroidism was achieved in a randomly selected subgroup and HbA1c and reticulocyte count was reassessed. HbA1c values and reticulocyte counts were compared with baseline in both the groups. Results: Hb A1c in patients initially selected was found to be significantly higher in hypothyroid group. HbA1c values in hyperthyroid patients were not significantly different from controls. HbA1c reduction and rise in reticulocyte count were significant in hypothyroid group following treatment without significant change in glucose level. Hb A1c did not change significantly following treatment in hyperthyroid group. The reticulocyte count, however, decreased significantly. Conclusion: Baseline HbA1c levels were found to be significantly higher in hypothyroid patients, which reduced significantly after achievement of euthyroidism without any change in glucose levels. Significant baseline or posttreatment change was not observed in hyperthyroid patients. Our study suggests that we should be cautious while interpreting HbA1c data in patients with hypothyroidism.

Prevalence of hypogonadism in male Type 2 diabetes mellitus patients with and without coronary artery disease p. 31
SV Madhu, M Aslam, AJ Aiman, A Siddiqui, S Dwivedi
Aim: The present study is carried out to investigate hypogonadism using serum testosterone levels in male Type 2 diabetes mellitus (T2DM) subjects with and without coronary artery disease (CAD). Subjects and Methods: A total of 150 age and body mass index-matched male subjects in the age group of 30–70 years were recruited in three groups; Group A - subjects with normal glucose tolerance, Group B - T2DM subjects without CAD, and Group C - T2DM subjects with CAD (n = 50 each group). Subjects with CAD were diagnosed on the basis of electrocardiogram, treadmill testing, stress echocardiography, or coronary angiography. Total testosterone (TT), free testosterone (FT), bioavailable testosterone, calculated FT and glycemic parameters were measured and compared between all the three study groups. One-way ANOVA followed by post hoc Tukey's test and Pearson's coefficient of correlation tests were used for analysis. Results: Hypogonadism (TT <3 ng/ml) was observed in 40% (20/50) of subjects in Group C and 32% (16/50) of subjects in Group B as compared to only 14% (7/50) of subjects in Group A (Groups A vs. B; P = 0.055, Groups A vs. C; P = 0.006 and Groups B vs. C; P = 0.53). Group C subjects had significantly lower levels of TT (3.55 ± 1.46 ng/ml vs. 4.73 ± 2.17 ng/ml, P = 0.005), calculated FT (0.062 ± 0.0255 pg/ml vs. 0.0951 ± 0.0508 pg/ml, P≤ 0.001), and bioavailable testosterone (1.48 ± 0.65 ng/ml vs. 2.18 ± 1.20 ng/ml, P ≤ 0.001) compared to control Group A subjects. There was no significant difference in any of the testosterone parameters between Groups A and B. Furthermore, an overall positive correlation was found between hypogonadism and CAD (r = 0.177, P = 0.030, n = 150). Conclusion: We observed hypogonadism as indicated by low testosterone levels in a significant proportion of male T2DM subjects with CAD.

A study of bone turnover markers in gestational diabetes mellitus p. 38
Sheelu Shafiq Siddiqi, Abhijit Girish Borse, Anjum Pervez, Shaheen Anjum
Introduction: Gestational diabetes is defined as carbohydrate intolerance resulting in hyperglycemia of variable severity with the first recognition during pregnancy. Established risk factors for gestational diabetes mellitus (GDM) are maternal age, obesity, family history of diabetes, etc. Vitamin D, parathyroid hormone (PTH), and various other hormones are known for their function in maintaining calcium and phosphorous homeostatic. Furthermore, Vitamin D, PTH serum ionized calcium, and alkaline phosphatase (ALP) have been reported to be altered with glucose homeostasis. The present study compares the bone markers in pregnant women with and without gestational diabetes. Materials and Methods: This cross-sectional study was conducted at outpatient antenatal check-up clinic and outpatient diabetic clinics at J. N. Medical College and Hospital, Aligarh. One hundred pregnant females, of which fifty with GDM and fifty without GDM, were included in the study from January 2014 to November 2015. Detailed history, physical examination, and anthropometric measurement were done. Bone turnover markers in the form of Vitamin D, parathyroid hormone, serum ionized calcium, and serum ALP were measured in pregnant women who had gestational diabetes which was compared with normal pregnant women. Results: In our study, the mean age of participate of GDM group was 28.2 ± 3 years, while the mean age group in non-GDM group was 25.44 ± 2.78 years. Ionized calcium in GDM was found to be 4.606 ± 0.354 mEq/L, while in non-GDM, it was 4.548 ± 0.384 mEq/L, P = 0.430. Vitamin D came out to be 21.80 ± 9.48 ng/ml, while it was 32.346 ± 8.37 ng/ml in non-GDM group. Serum PTH in GDM group was 71.436 ± 36.189 pg/ml and 37.168 ± 8.128 pg/ml in nondiabetic gestational group. Serum ALP in GDM group was 9.1 ± 4.56 KA U/dl and 6.98 ± 2.2 KA U/dl in nondiabetic gestational group, P - 0.0038. In GDM group, there was a significant negative linear correlation between PTH and 25-hydroxyvitamin D with research correlation coefficient r = −0.9073, P = 0; there was a significant positive linear correlation coefficient between PTH and ALP with Persian correlation coefficient r = 0.6597, P = 0; there was no statistically significant correlation between PTH and ionized calcium r = 0.1416, P = 0.3267. Conclusion: All GDM subjects should ideally be screened for serum calcium, vitamin D, PTH, ALP. If found impaired should immediately be corrected in order to prevent its adverse effects on maternal and fetal outcome. Vitamin D supplementation should ideally be initiated in all GDM females even if the above parameters are not investigated in Indian setup.

Thyroid profile and autoantibodies in Type 1 diabetes subjects: A perspective from Eastern India p. 45
Debmalya Sanyal, Anirban Majumder, Soumyabrata Roy Chaudhuri, Sudip Chatterjee
Context: There has been a rise in the incidence of type 1 diabetes mellitus (T1DM) in India. The prevalence of thyroid autoantibodies and thyroid dysfunction is common in T1DM. Aims: The aim of this study is to determine the incidence of thyroid dysfunction and thyroid autoantibodies in T1DM subjects, without any history of thyroid disease, and the prevalence of glutamic acid decarboxylase (GAD) antibody, Islet antigen-2 antibody (IA2), thyroid peroxidase (TPO), and thyroglobulin autoantibodies (Tg-AB) in T1DM subjects. Settings and Design: This was a cross-sectional clinical-based study. Subjects and Methods: Fifty subjects (29 males, 31 females) with T1DM and without any history of thyroid dysfunction were included in the study. All subjects were tested for GAD antibody, IA2 antibody, TPO antibody, thyroglobulin antibody, free thyroxine, and thyroid-stimulating hormone. Statistical Analysis Used: A Chi-square/pooled Chi-square test was used to assess the trends in the prevalence of hypothyroidism. A two-tailed P< 0.05 was considered statistically significant. Results: The mean age of the subjects was 23.50 years. 9.8% of subjects were below the age of 12 years, 27.45% of subjects were of age 12–18 years, 37.25% of subjects were of age 19–30 years, and 25.49% of subjects were above 30 years. 78% were positive autoantibody for GAD, 30% for IA-2, 24% for TPO, and 16% were positive for Tg-AB. A total of 6.0% of T1DM subjects had evidence of clinical hypothyroidism, but the prevalence of subclinical hyperthyroidism (SCH) varied from 32% to 68.0% for we considered different definitions of SCH as advocated by different guidelines. All subjects with overt hypothyroidism had positive GAD and thyroid autoantibodies. One (2%) subject had clinical hyperthyroidism with strongly positive GAD, TPO, and Tg-AB. Conclusions: We found a high prevalence of GAD, IA2, TPO, and Tg-AB in our T1DM subjects. A substantial proportion of our subjects had undiagnosed thyroid dysfunction with a preponderance of subclinical hypothyroidism. All T1DM subjects with overt hypothyroidism or hyperthyroidism had positive GAD and thyroid autoantibodies. The high prevalence of undiagnosed thyroid dysfunction highlights the importance of regular thyroid screening in T1DM subjects.

Usefulness of pre- and post-operative calcium and Vitamin D supplementation in prevention of hypocalcemia after total thyroidectomy: A randomized controlled trial p. 51
Sumiya Jaan, Ashish Sehgal, Rauf Ahmad Wani, Muneer Ahmad Wani, Khursheed Alam Wani, Bashir Ahmad Laway
Background: Total thyroidectomy (TT) is a commonly performed surgery and postoperative hypocalcemia is a major detriment to early discharge. The aim of this randomized controlled trial was to ascertain the usefulness of routine pre- and post-operative calcium and Vitamin D supplementation in prevention of hypocalcemia after TT. Materials and Methods: Sixty consecutive patients who underwent total or near TT from February 2013 to August 2014 were included in the study. They were randomly divided into two groups - Group 1 received oral calcium (500 mg every 6 h) and Vitamin D (calcitriol 0.25 mcg every 6 h) 7 days before and 7 days after the surgery; and Group 2 did not receive supplementation. Symptoms and signs of hypocalcemia were monitored. Calcium profile was measured pre- and post-operatively at 6, 12, 24, 48, 72 h, and on 30th day. Hypocalcemia after surgery was either symptomatic or laboratory documented. Serum calcium level ≤ 8.5 mg/dl was considered as laboratory hypocalcemia. Results: Twelve patients from Group 2, and 3 patients from Group 1 developed symptomatic hypocalcemia (P < 0.01). Laboratory hypocalcemia within postoperative 24 h was comparable between two groups, but more patients of Group 2 compared to Group 1 developed hypocalcemia at 48 h (6 and 13, respectively; P = 0.04) and at 72 h after surgery (5 and 14, respectively; P = 0.01). Twenty-four hours postoperative serum calcium level was significantly associated with grade of goiter, preoperative calcium, and nature of thyroid disease (benign or malignant). On multiple linear regression analysis, preoperative serum calcium was only independent variable significantly associated with development of 24 h post-TT hypocalcemia. Conclusion: Routine pre- and post-TT calcium and Vitamin D supplementation can significantly reduce postoperative hypocalcemia.

Factors associated with high stress levels in adults with diabetes mellitus attending a tertiary diabetes care center, Chennai, Tamil Nadu, India p. 56
Muthappan Sendhilkumar, Jaya Prasad Tripathy, Anthony D Harries, Amol R Dongre, Mohan Deepa, Ashok Vidyulatha, Subramanian Poongothai, Ulaganathan Venkatesan, Ranjit Mohan Anjana, Viswanathan Mohan
Objective: We aimed to determine perceived stress levels among adults aged >20 years with type 2 diabetes mellitus (DM) in a tertiary care diabetes center, Chennai, Tamil Nadu, India, assess their association with sociodemographic and clinical characteristics and assess the possible risk factors for stress and coping strategies. Methods: A mixed-methods (triangulation design) study with quantitative methodology (survey) and qualitative methodology (interviews) was carried out. Stress levels were assessed among type 2 DM patients attending a diabetes clinic using a 5-point perceived stress scale-10. One-on-one interviews were carried out with 376 participants with DM having high/very high stress levels to understand the reasons for perceived stress and explore their coping mechanisms. Results: The prevalence of high/very high stress was 35% among DM patients. Age 30–40 years, working in professional jobs, and lack of physical activity were factors significantly associated with stress. The perceived major stress inducers were related to family, work, financial issues, and the disease itself. Conclusions: This study showed high levels of stress in more than one-third of DM patients. Potential solutions include regular, formal assessment of stress levels in the clinic, providing integrated counseling and psychological care for DM patients, and promoting physical activity.

A study to evaluate the prevalence of hypogonadism in Indian males with Type-2 diabetes mellitus p. 64
Pankaj Kumar Agarwal, Parminder Singh, Subhankar Chowdhury, SK Sharma, Anirban Majumdar, Parag Shah, Rakesh Sahay, S Vageesh Ayyar, Hemant Phatale, Chandar M Batra, Raeesuddin Syed, Pradeep Shetty
Background: A high prevalence of hypogonadism in men with Type-2 diabetes mellitus (T2DM) has been reported worldwide. Objectives: To evaluate the prevalence of hypogonadism in Indian males with T2DM and assess the primary and secondary hypogonadism along with androgen deficiency. Materials and Methods: In this cross-sectional study, 900 men with T2DM were evaluated using androgen deficiency in aging male questionnaire. They were screened for demographic characteristics, gonadal hormone levels, lipid profile, and glycosylated hemoglobin. Results: The prevalence of hypogonadism in T2DM patients was found to be 20.7% (186 out of 900). Hypogonadism was of testicular origin (primary) in 48/186 (25.8%) patients, of pituitary or hypothalamic origin (secondary) in 14/186 (7.53%), and remaining 124/186 (66.67%) patients were found to have low testosterone with the inappropriate normal level of luteinizing hormone and Follicle-stimulating hormone. 451/900 (50.1%) patients were only symptomatic but had normal testosterone levels. Further 263 patients out 900 were asymptomatic, of which 51/900 (5.7%) patients had low levels of testosterone and 212/900 (23.5%) patients had normal testosterone level without symptoms. There were no deaths or other serious adverse events except mild pyrexia which was not related to the study. Conclusion: Hypogonadism diagnosis, at times, might not be validated with the help of androgen deficiency questionnaire or symptoms only. Given the large number of patients of T2DM in India, the incidence of hypogonadism is more in diabetic patients as compared to the general population. Hence, implementation of screening programs in diabetic patients is necessary to understand and detect individuals with low serum total testosterone at any early stage and to supplement testosterone accordingly.

The effects of meal glycemic load on blood glucose levels of adults with different body mass indexes p. 71
Tuba Yalcin, Ayhan Al, Neslişah Rakıcıoğlu
Aims: The aim was to determine the effect of meal glycemic load (GL) on blood glucose levels of healthy people with different body mass indexes (BMIs). Methods: Thirty healthy controls were included in this study. The participants were divided into two groups according to their BMI as normal group (BMI = 18.5–24.9 kg/m2, n = 15) and overweight group (BMI = 25.0–29.9 kg/m2, n = 15). Dietary assessment was done by the 24-h recall method for 3 successive days. Cases were fed by breakfasts with two different GL on consecutive days. Energy values of the test meal, adjusted to meet 25% of daily energy requirements of each case, were identical in low and high GL meal (483 kcal and 482 kcal, respectively). Finger-prick capillary blood samples were taken on 0, 15, 30, 45, 60, 90, and 120 min. Results: Average daily energy intake in normal and overweight group was found as 2514.3 ± 223.8 kcal, 2064.1 ± 521.6 kcal and 2211.4 ± 368.7 kcal, 2494.8 ± 918 kcal in males and females, respectively. Blood glucose level was increased and remained more stable in both high GL meal groups compared to low (P < 0.05). The effects of GL on BMI classified groups were also found different. High GL meal was found to be more effective for increasing blood glucose level, especially on overweight group (P < 0.05). Conclusions: The effects of GL meal were found to be different on normal and overweight individuals. The high GL meals were more effective to increase the blood glucose level than low GL meal, especially on overweight people.

Preoperative zoledronic acid therapy prevent hungry bone syndrome in patients with primary hyperparathyroidism p. 76
Sabaretnam Mayilvaganan, HA Vijaya Sarathi, C Shivaprasad
Background: Hungry bone syndrome is a common complication of surgery for primary hyperparathyroidism in India which often leads to prolonged hospitalization. There are varying reports on the use and efficacy of bisphosphonates in the prevention of hungry bone syndrome. Methods: We retrospectively analyzed the effect of preoperative bisphosphonate therapy on rates of hungry bone syndrome in our patients with primary hyperparathyroidism. A total of 19 patients underwent surgery for primary hyperparathyroidism at our institute between January 2013 and June 2015 among whom eight did not receive preoperative bisphosphonates and 11 received intravenous zoledronic acid 4 mg, 24–48 h preoperatively. Results: There was no significant difference between the two groups with respect to age, gender, duration of symptoms, preoperative serum calcium, phosphorus, parathyroid hormone, alkaline phosphatase, and the presence of radiological evidence of hyperparathyroid bone disease also did not differ between the groups. Three out of the eight patients who did not receive preoperative zoledronic acid therapy had hungry bone syndrome but none in the zoledronic acid group. The prevalence of hungry bone syndrome tended to be lower in the zoledronic acid group (P = 0.058). The need for intravenous calcium and duration of postoperative hospital stay were significantly lesser in the zoledronic acid group. Conclusion: Preoperative intravenous zoledronic acid significantly reduces the need for intravenous calcium therapy and duration of postoperative hospital stay and seems a promising option to reduce the rate of hungry bone syndrome in patients with primary hyperparathyroidism.

Pituitary dysfunction in traumatic brain injury: Is evaluation in the acute phase worthwhile? p. 80
Pradip P Dalwadi, Nikhil M Bhagwat, Parimal S Tayde, Ameya S Joshi, Premlata K Varthakavi
Introduction: Traumatic brain injury (TBI) is an under-recognized cause of hypopituitarism. According to recent data, it could be more frequent than previously known. However, there is a scarcity of data in Indian population. Aims: The main aim of the study was to determine the prevalence of pituitary hormone deficiencies in the acute phase of TBI. The secondary objectives were to correlate the severity of trauma with basal hormone levels and to determine whether initial hormone deficiencies predict mortality. Subjects and Methods: Forty-nine TBI patients (41 men and 8 women) were included in this study. Pituitary functions were evaluated within 24 h of admission. Results: Gonadotropin deficiency was found in 65.3% patient while 46.9% had low insulin-like growth factor-1, 12.24% had cortisol level <7 mcg/dl. Cortisol and prolactin level were positively correlated with the severity of TBI suggestive of stress response. Free triiodothyronine (fT3) and free thyroxine were significantly lower in patients with increasing severity of tuberculosis. Logistic regression analysis revealed that mortality after TBI was unrelated to the basal pituitary hormone levels except low T3 level, which was found to be positively related to mortality. Conclusions: Pituitary dysfunction is common after TBI and the most commonly affected axes are growth hormone and gonadotropin axis. Low fT3 correlates best with mortality. During the acute phase of TBI, at least an assessment of cortisol is vital as undetected cortisol deficiency can be life-threatening

Improving iodine nutritional status and increasing prevalence of autoimmune thyroiditis in children p. 85
Srinivasan Palaniappan, Lakshmi Shanmughavelu, Hemchand K Prasad, Sundari Subramaniam, Nedunchezian Krishnamoorthy, Lakshmi Lakkappa
Objective: The objective of this study is to evaluate the link between excess iodine intake as evidenced by increased urinary iodine excretion (UIE) and autoimmune thyroiditis in children and to assess the correlation between UIE and thyroid microsomal antibody (thyroid peroxidase [TPO]) titers in children. Materials and Methods: All children with goiter between age group 6 and 12 years, were subjected to blood tests for free thyroxine, thyroid stimulating hormone, and TPO antibody, fine needle aspiration was advised for all children with goiter. Forty-three children with confirmed autoimmune thyroiditis served as cases, and 43 children with euthyroid goiter with workup negative for autoimmune thyroiditis and iodine deficiency were enrolled as controls. UIE was estimated in spot urine sample for both cases and controls. The levels of urinary iodine were compared between cases and controls. Results: The levels of urinary iodine were significantly higher in children with autoimmune thyroiditis as compared with control. There was a positive correlation between UIE and antimicrosomal antibody titers among cases. Among cases 65% children had subclinical hypothyroidism, 27.9% had overt hypothyroidism and 7% of cases, and 100% of controls had euthyroid functional status. Excessive (≥300 μg/L) UIE was strongly associated with autoimmune thyroiditis. If the UIE level is ≥ 300 μg/L, then there is 17.94 times higher chance of having amiodarone-induced thyrotoxicosis than those who have UIE level < 300 μg/L (P < 0.001). Conclusions: A possible association between increased iodine intake and autoimmune thyroiditis was found in this study. Excessive iodine intake may trigger thyroid autoimmunity and eventually thyroid hypofunction.

Noncommunicable disease in rural India: Are we seriously underestimating the risk? The Nallampatti noncommunicable disease study p. 90
Krishnan Swaminathan, Ganesh Veerasekar, Sujatha Kuppusamy, Mohanraj Sundaresan, Ganesan Velmurugan, Nalla G Palaniswami
Aim: To assess the prevalence of noncommunicable diseases in a true rural farming population in South India and compare the data with the landmark contemporary Indian Council of Medical Research-India Diabetes (ICMR-INDIAB) study. Methods: Local Ethics Committee approval and informed consent was obtained from all participants. Inclusion criteria were participants, aged ≥20 and ≤85 years, from Nallampatti, a classical farming village from Tamil Nadu state, India. All participants were administered a detailed questionnaire, had anthropometric measurements including height, weight, and waist circumference. Bloods were drawn for random blood glucose, glycated hemoglobin (HbA1c), nonfasting lipid profile, Cystatin C, uric acid, and hemoglobin. All participants had carotid intima-media thickness (CIMT) done by high-resolution B-mode carotid ultrasound. Results: More than 50% of the population had either diabetes or prediabetes based on HbA1c. Nearly, 40% of the population had hypertension with suboptimal control in those with known hypertension. Nearly, a third of the population had dyslipidemia, elevated cystatin C levels, and abnormal CIMT. The burden was higher than the comparable ICMR-INDIAB study in rural Tamil Nadu. Conclusion: One-third to one-half of this rural farming population is at risk of cardiovascular disease, with poor control of preexisting cardiovascular risk factors. Current Indian data may underestimate the risk in different ethnic populations and regions of India. Long-term follow-up of this cohort for the incident cardiovascular disease will shed light on the true cardiovascular risk in a typical South Indian rural farming population.

Interrelationship between serum 25-hydroxyvitamin D3 concentration and lipid profiles in premenopausal Indian women p. 96
Pinal A Patel, Prerna P Patel, Zulf Mughal, Raja Padidela, Ashish D Patel, Vivek Patwardhan, Shashi A Chiplonkar, Vaman Khadilkar, Anuradha Khadilkar
Context: Vitamin D deficiency is prevalent worldwide, and observational studies have associated it with an atherogenic lipid profile. Aim: To determine the interrelationship between Vitamin D and lipid profile in apparently healthy premenopausal Indian women, considering confounding factors such as lifestyle that independently influence lipids. Setting and Design: Cross-sectional study. Subjects and Methods: One hundred and twenty healthy premenopausal women (20–45 year) were recruited from Gujarat, India. Data were collected on anthropometry, physical activity, sunlight exposure, and diet. Fasting blood samples were collected for the measurement of serum 25-hydroxyvitamin D3 (25[OH]D), parathyroid hormone, and lipid profile. Statistical Analysis: Pearson's correlation coefficient was used to derive correlation between serum 25(OH)D concentrations and serum lipids. Results: Ninety-three percent women showed Vitamin D deficiency (serum 25[OH]D < 20 ng/ml). Serum 25(OH)D concentrations showed significant inverse correlation with total cholesterol (TC) (r = −0.202, P = 0.027), triglycerides (TG) (r = −0.284, P = 0.002), and low-density lipoprotein-cholesterol (LDL-C) (r = −0.184, P = 0.044) and positive correlation with high-density lipoprotein-cholesterol (HDL-C) (r = 0.250, P = 0.006). On dichotomizing the population according to median 25(OH)D concentration (11.1 ng/dl), no significant differences were observed between the groups for anthropometry, sunlight exposure, and lifestyle. Serum lipid profiles were significantly different, above median serum 25(OH)D concentration group showed favorable serum lipids (TC: 179.3 ± 30 vs. 191.8 ± 31.7 mg/dl; TG: 140 ± 39.1 vs. 165.5 ± 53.4 mg/dl; LDL-C: 100 ± 30.2 vs. 112 ± 32 mg/dl; HDL-C: 53 ± 14 vs. 47.6 ± 9.3 mg/dl)(P < 0.05). Conclusions: This study demonstrates that association of 25(OH)D concentrations with lipid profile even after considering lifestyle factors which independently influence lipids. Intervention trials would be required to prove this association to be causation.

Aim: Diabetic retinopathy (DR) is the most common preventable cause of blindness where early detection and treatment can be sight-saving. Search for biomarkers of the disease has been relentless. We aimed to determine whether lipoproteins apolipoproteins A1 and B1 (Apo-A1 and Apo-B1) have stronger associations with DR in contrast to conventionally measured low-density lipoprotein (LDL) and high-density lipoprotein cholesterol levels. Materials and Methods: We performed a cross-sectional study and studied 117 patients. Serum lipid profile was assessed by autoanalyzer. Serum Apo-A1 and Apo-B were measured using immunoturbidimetric kit on an autoanalyzer. Apo-B/A1 ratio was calculated. Retinopathy was graded from the digital retinal photographs, taken with nonmydriatic auto fundus camera and classified according to International Clinical DR Disease Severity Scale. Results: Mean Apo-A1 for mild, moderate, severe retinopathy, and proliferative DR (PDR) shows a significant negative correlation (P = 0.001) with severity of retinopathy. Mean Apo-B for mild, moderate, severe, PDR displayed a significant positive correlation with severity of retinopathy (P = 0.001). Mean Apo-B/A1 for mild, moderate, severe, PDR showed highly significant positive correlation with severity of retinopathy (P < 0.001). In contrast, mean LDL for mild, moderate, severe, PDR showed insignificant association with severity of DR (P = 0.081). Conclusion: Apo-A1 and Apo-B have a stronger association with the development of DR than traditional lipids and can thus facilitate early detection and treatment of the disease.

Obstructive sleep apnea in Type 2 diabetes and impact of continuous positive airway pressure therapy on glycemic control p. 106
Javid Ahmad Malik, Shariq Rashid Masoodi, Sheikh Shoib
Background: Obstructive sleep apnea (OSA) and type 2 diabetes mellitus (T2DM) are two interacting epidemics both with high prevalence and morbidity. Both epidemiologic and clinical studies suggest that the majority of patients with T2DM also have OSA and untreated OSA in these patients results in poor glycemic control leading to acceleration of diabetes-related complications. Objectives: To assess the prevalence and severity of OSA in T2DM patients and to assess the impact of OSA treatment on presenting symptoms and hemoglobin A1c (HbA1c). Methods: We performed polysomnography (PSG) studies and measured HbA1c in 62 consecutive patients with T2DM that were referred from various subspecialty clinics from July 2011 to August 2013. Results: In our 62 diabetic patients, 59 (95.2%) had abnormal PSG. Based on Apnea–Hypopnea Index (AHI) score, 3 (5.1%) patients had mild, 28 (47.5%) had moderate, and 28 (47.5%) had severe OSA. The mean AHI of diabetic patients was significantly more than nondiabetic patients, i.e., 25.7 versus 19.7 (P = 0.001). Variables that significantly correlated with the presence of OSA include age, gender, body mass index (BMI), hypertension, diabetes, and cardiovascular disease (P < 0.05); however, on logistic regression only BMI, hypertension, and nocturia correlated with OSA. Overall, 59% of diabetic patients showed improvement in their glycemic control as measured by HbA1c with continuous positive airway pressure (CPAP) treatment. Significant, moderate, and mild categories of treatment response were respectively observed in 7%, 20%, and 32% of patients. Conclusion: Treatment of OSA with CPAP reduces HbA1c in a significant number of diabetics.

Relevance of the triglyceride-to-high-density lipoprotein cholesterol ratio as an important lipid fraction in apparently healthy, young, and middle-aged Indian men p. 113
Aparna Kohli, Anupa Siddhu, Ravindra M Pandey, K Srinath Reddy
Context: Cardiovascular disease (CVD) is the largest cause of mortality in Indians. Insulin resistance and related dyslipidemia of increased triglyceride (TG), small dense low-density lipoprotein (sd-LDL) particles, and decreased high-density lipoprotein-cholesterol (HDL-C) are associated with increased risk of CVD. TG/HDL-C ratio could be a potential surrogate marker for this South Asian phenotype. Data are scarce on the relevance of TG/HDL-C ratio as a useful lipid marker among Indians. Aims: To study the prevalence of TG/HDL-C ratio among healthy, young, and middle-aged Indian men (25–44 years) and its relationship with other lipid and nonlipid factors. Subjects and Methods: In this cross-sectional analysis, fasting blood samples from 236 healthy participants recruited from an urban community setting were tested for TG/HDL-C ratio, HDL-C, TG, total cholesterol (TC), non-HDL-C, TC/HDL-C, high-sensitivity C-reactive protein, body mass index (BMI), and body fat. Results: Mean (standard deviation) age of participants was 34.7 (7.7) years; median (interquartile range) TG/HDL-C ratio was 4 (2.85-5.2). More than half (51.3%) the participants (n = 121) recorded abnormal TG/HDL-C ratio (≥4.0). Across tertiles of TG/HDL-C ratio, there was a significant trend of higher conventional lipid parameters such as non-HDL-C*, TC/HDL-C ratio*, TG*, HDL-C*, TC**; and non-lipid parameters body-fat* and BMI*** (*P < 0.001, **P = 0.015, ***P = 0.002). LDL-C showed moderate and nonsignificant (P = 0.646) increase across tertiles. Conclusion: In a sample of apparently healthy, young, and middle-aged Indian men abnormal TG/HDL-C ratio levels were observed among more than half the participants. The TG/HDL-C ratio was closely associated with other lipid parameters and measures of adiposity, such as BMI and body fat, apart from its previously documented unique association with sd-LDL particles. TG/HDL-C ratio should be evaluated in future for risk prediction of incident CVD among Indians.

Juvva Gowtham Kumar, KPP Abhilash, Rama Prakasha Saya, Neeha Tadipaneni, J Maheedhar Bose
Background: Hypoglycemia is one among the leading causes for Emergency Department (ED) visits and is the most common and easily preventable endocrine emergency. This study is aimed at assessing the incidence and elucidating the underlying causes of hypoglycemia. Materials and Methods: A retrospective, observational study which included patients registering in ED with a finger prick blood glucose ≤60 mg/dl at the time of arrival. All patients aged above 15 years with the above inclusion criteria during the period of August 2010 to July 2013 were selected. The study group was categorized based on diabetic status into diabetic and nondiabetic groups. Results: A total of 1196 hypoglycemic episodes encountered at the ED during the study period were included, and of which 772 with complete data were analyzed. Underlying causes for hypoglycemia in the diabetic group (535) mainly included medication related 320 (59.81%), infections 108 (20.19%), and chronic kidney disease 61 (11.40%). Common underlying causes of hypoglycemia in nondiabetic group (237, 30.69%) included infections 107 (45.15%), acute/chronic liver disease 42 (17.72%), and malignancies 22 (9.28%). Among diabetic subjects on antidiabetic medications (n = 320), distribution over 24 h duration clearly reported two peaks at 8th and 21st h. The incidence of hypoglycemia and death per 1000 ED visits were 16.41 and 0.73 in 2011, 16.19 and 0.78 in 2012, 17.20 and 1.22 in 2013 with an average of 16.51 and 0.91, respectively. Conclusion: Bimodal distribution with peaks in incidences of hypoglycemic attacks at 8th and 21st h based on hourly distribution in a day can be correlated with the times just before next meal. None of the patients should leave ED without proper evaluation of the etiology of hypoglycemia and the problem should be addressed at each individual level. Increasing incidence of death over the years is alarming, and further studies are needed to conclude the root cause.

Parag Himatrao Bawaskar, Himmatrao Saluba Bawaskar, Pramodini Himmatrao Bawaskar, Abhijit Patilbuwa Pakhare
Background: Despite abundant sunshine, Vitamin D deficiency is prevalent in urban India. However, reports on analyzing Vitamin D status from rural Indian population are scanty. Here, we have evaluated Vitamin D status in patients attending outpatient department (OPD) in a rural Indian hospital setting. Methods: A hospital-based cross-sectional study was conducted at a secondary level rural hospital in patients attending medicine OPD. After obtaining informed consent, demographic information was collected from consecutive adult patients along with 3 ml blood sample for Vitamin D analysis using electro chemiluminescene on cobas elecys E411 fully automated system. Vitamin D levels were compared across various groups by using Mann–Whitney or Kruskal–Wallis tests, and multiple linear regression analysis was performed to identify the predictors of Vitamin D level. Results: A total of 640 patients were enrolled in the study, and the prevalence of Vitamin D deficiency (<20 ng/ml) was found to be 65.4% with 95% confidence interval of 61.7–69.1%. On univariate analysis, Vitamin D levels were statistically significantly lower among younger age group, those who have dark complexion, wearing Burkha (veil), and those who were not adequately exposed to sunlight. After multiple linear regressions, dark complexion, wearing Burkha, inadequate exposure to sunlight, and presence of diabetes were identified as statistically significant predictors of Vitamin D deficiency. Conclusion: We report a high prevalence of Vitamin-D deficiency in patients attending medicine OPD. Thus, patients with generalized complaints may be evaluated for serum Vitamin D levels.

Effect of oral versus intramuscular Vitamin D replacement in apparently healthy adults with Vitamin D deficiency p. 131
Nitin Gupta, Khalid J Farooqui, Chandar M Batra, Raman K Marwaha, Ambrish Mithal
Context: A number of controversies exist regarding appropriate treatment strategy for Vitamin D deficiency. Aims: The aim of this study was to investigate the efficacy of equivalent doses of oral cholecalciferol (60,000 IU weekly for 5 weeks) versus intramuscular (IM) cholecalciferol (300,000 IU) in correcting Vitamin D deficiency in apparently healthy volunteers working in a hospital. Settings and Design: Prospective randomized open-label single institution study. Subjects and Methods: This study enrolled 40 apparently healthy adults with Vitamin D deficiency into 2 arms. The oral cholecalciferol group (n = 20) received oral cholecalciferol 60,000 IU weekly for 5 weeks while the IM cholecalciferol group (n = 20) received a single injection of cholecalciferol 300,000 IU. The main outcome measure was serum 25-hydroxyvitamin D (25OHD) levels at baseline, 6 and 12 weeks after the intervention. Statistical Analysis Used: Differences in serum 25OHD and other biochemical parameters at baseline and follow-up were analyzed using general linear model. Results: Mean 25OHD level at baseline was 5.99 ± 1.07 ng/mL and 7.40 ± 1.13 ng/mL (P = 0.332) in the oral cholecalciferol and IM cholecalciferol group, respectively. In the oral cholecalciferol group, serum 25OHD level was 20.20 ± 1.65 ng/mL at 6 weeks and 16.66 ± 1.36 ng/mL at 12 weeks. The corresponding serum 25OHD levels in the IM cholecalciferol group were 20.74 ± 1.81 ng/mL and 25.46 ± 1.37 ng/mL at 6 and 12 weeks, respectively. At 12 weeks, the mean 25OHD levels in IM cholecalciferol group was higher as compared to the oral cholecalciferol group (25.46 ± 1.37 vs. 16.66 ± 1.36 ng/mL; P< 0.001). Conclusions: Both oral and IM routes are effective for the treatment of Vitamin D deficiency. 25-hydroxyvitamin D levels in the IM cholecalciferol group showed a sustained increase from baseline.

Jitendra Sharma, Sachin Chittawar, Ram Singh Maniram, TN Dubey, Ambrish Singh
Background: Stress hyperglycemia is common in patients presenting at the emergency medical ward and is associated with poor prognosis and increased risk of mortality. Aims and Objective: To study and determine the prevalence and factors associated with stress hyperglycemia. Materials and Methods: A cross-sectional observational study was performed on 536 nondiabetic patients presented to the Intensive Care Unit (ICU) at Gandhi Medical College and allied Hamidia Hospital, Bhopal, between March 31, 2015, and May 28, 2015. A detailed history including demographic profile, presence of chronic disease, history of hospitalization and ICU admission, surgical status, and major reason for ICU admission (i.e., predominant diagnostic category) was collected. Hematological and other parameters based on profile of study population were also analyzed. Results: Out of 536 patients, 109 (20.33%) had stress hyperglycemia. Out of 109 patients with stress hyperglycemia, 87 (16.23%) patients had glycated hemoglobin (HbA1c) <5.7% and 22 (4.10%) patients had HbA1c between 5.7% and 6.4%. Mean age of the study population was 40.27 ± 1.44 years, with male dominance. Mean random blood glucose level was 181.46 ± 3.80 mg/dl. Frequency of stress hyperglycemia was 24.13% in stroke, 19.54% in multiple organ dysfunction syndrome (MODS), 17.24% in chronic kidney disease (CKD), 12.64% in central nervous system (CNS) infection, 8.05% in chronic liver disease (CLD), and 8.05% in seizure patients. Association between stroke and stress hyperglycemia was significant (P = 0.036). Association between hospital stay more than 7 days and stress hyperglycemia was significant in stroke patients (P = 0.0029), CKD patients (P = 0.0036), CLD (P = 0.0099), and MODS patients (P = 0.0328). Conclusions: The factors associated with stress hyperglycemia were stroke, MODS, CKD, CNS infection, CLD, seizure patients, with prolonged hospital stay and expected proportion.

High incidence of abnormal glucose metabolism in acute coronary syndrome patients at a moderate altitude: A sub-Himalayan study p. 142
Jitender Mokta, Subash Kumar, Neeraj Ganju, Kiran Mokta, Prashant Kumar Panda, Swatantra Gupta
Background: Abnormal glucose metabolic status at admission is an important marker of future cardiovascular events and long-term mortality after acute coronary syndrome (ACS), whether or not they are known diabetics. Objective: The aims were to study the prevalence of abnormal glucose metabolism in ACS patients and to compare the different methods of diagnosing diabetes in ACS patients. Methods: We did a prospective study. About 250 consecutive nondiabetic patients (200 men and 50 women) with ACS admitted to a tertiary care institute of Himachal Pradesh in 1 year were enrolled. Admission plasma glucose, next morning fasting plasma glucose (FPG), A1C, and a standardized 75-g oral glucose tolerance test (OGTT) 72 h after admission were done. Glucose metabolism was categorized as normal glucose metabolism, impaired glucose metabolism (impaired fasting glucose or impaired glucose tolerance [IGT]), and diabetes. Diabetes was arbitrarily classified further as undiagnosed (HBA1c ≥6.5%) or possibly stress diabetes (HBA1c <6.5%). A repeat OGTT after 3 months in objects with IGT and stress hyperglycemia at a time of admission was done. Results: The mean age was 54 ± 12.46 years. The mean plasma glucose at admission was 124 ± 53.96 mg/dL, and the mean FPG was 102 ± 27.07 mg/dL. The mean 2-h postglucose load concentration was 159.5 ± 56.58 mg/dL. At baseline, 95 (38%) had normal glucose metabolism, 95 (38%) had impaired glucose metabolism (IGT and or IGT) and 60 (24%) had diabetes; 48 (19.2%) were undiagnosed diabetes and 12 (4.8%) had stress hyperglycemia. At follow up 58.66% and 55.55% of patients with impaired glucose tolerance and stress hyperglycemia continued to have impaired glucose tolerance respectively. About 75 gm OGTT has highest sensitivity and specificity to diagnose diabetes, whereas A1C most specific to rule out stress hyperglycemia. Conclusions: In this small hilly state of India, abnormal glucose metabolism (previously undiagnosed diabetes and IGT) is common in patients admitted with ACS. Abnormal glucometabolic status can be detected early in the postadmission period. Our results further suggest that 75-g OGTT remained the gold standard test to detect diabetes and could be used before discharge to diagnose diabetes.

Reported hypoglycemia in Type 2 diabetes mellitus patients: Prevalence and practices-a hospital-based study p. 148
Vanishree Shriraam, Shriraam Mahadevan, M Anitharani, Nalini Sirala Jagadeesh, Sreelekha Bhaskara Kurup, TA Vidya, Krishna G Seshadri
Introduction: Hypoglycemia tops the list of hurdles in preventing tight glycemic control in diabetic patients. It is even considered as a cardiovascular risk factor. However, it continues to be a neglected complication with very limited epidemiological data in our country. Aim: To study the self-reported prevalence of hypoglycemia among type 2 diabetic patients and the practices adopted by them during and after the episodes to manage and avert future occurrences. Materials and Methods: It is a questionnaire-based cross-sectional study done using systematic random sampling selecting every 5th patient attending the diabetic Out-Patient (OP) in a tertiary medical college hospital. Results: There were 366 participants with median age of 60 years. Around 96% reported any one symptom of hypoglycemia, but 78% had eaten following the episode and got relieved of the symptoms. Weakness (76.2%) and dizziness (74%) were the most common symptoms reported by the patients. A quarter of them reported having severe attacks requiring somebody's assistance. Most patients resorted to timely meals (85%) to avert future attacks. Patients who took insulin along with oral hypoglycemic agents (OHAs) were at a higher risk (OR = 2.3) for hypoglycemia compared to patients taking only OHAs (P < 0.01). Conclusion: The reported prevalence of hypoglycemia among type 2 diabetes patients is quite high. This finding reiterates the importance of enquiring and educating every diabetic patient about hypoglycemic episodes during every health visit.

Long-term cardiac (valvulopathy) safety of cabergoline in prolactinoma p. 154
Shruti Khare, Anurag R Lila, Rishikesh Patil, Milind Phadke, Prafulla Kerkar, Tushar Bandgar, Nalini S Shah
Background: Clinical relevance of association of cabergoline use for hyperprolactinemia and cardiac valvulopathy remains unclear. Objective: The aim of the study was to determine the prevalence of valvular heart abnormalities in patients taking cabergoline for the treatment of prolactinoma and to explore any associations with the cumulative dose of drug used. Design: A cross-sectional echocardiographic study was performed in patients who were receiving cabergoline therapy for prolactinoma. Results: Hundred (61 females, 39 males) prolactinoma cases (81 macroprolactinoma and 19 microprolactinoma) were included in the study. The mean age at presentation was 33.9 ± 9.0 years (range: 16–58 years). The mean duration of treatment was 53.11 ± 43.15 months (range: 12–155 months). The mean cumulative dose was 308.6 ± 290.2 mg (range: 26–1196 mg; interquartile range: 104–416 mg). Mild mitral regurgitation was present in one patient (cumulative cabergoline dose 104 mg). Mild tricuspid regurgitation was present in another two patients (cumulative cabergoline dose 52 mg and 104 mg). Aortic and pulmonary valve functioning was normal in all the cases. There were no cases of significant valvular regurgitation (moderate to severe, Grade 3–4). None of the patients had morphological abnormalities such as thickening, calcification, and restricted mobility of any of the cardiac valves. Conclusion: Cabergoline appears to be safe in patients with prolactinoma up to the cumulative dose of ~300 mg. The screening for valvulopathy should be restricted to those with higher cumulative cabergoline exposure.

Adolescent gynecomastia is associated with a high incidence of obesity, dysglycemia, and family background of diabetes mellitus p. 160
Bindu Kulshreshtha, Arora Arpita, Patnaik T Rajesh, Bhattacharya Sameek, Deep Dutta, Sharma Neera, Mohsin Mohd
Background: Gynecomastia during adolescence is common though etiology is not clear. We studied the clinical and hormonal profile of adolescent patients with gynecomastia. Methodology: Patients who had onset of breast development between age 10 and 20 years were included in this study. Their clinical profile, biochemical, and hormonal parameters were studied. Results: Of 94 patients with gynecomastia, 4 had hypogonadotropic hypogonadism, 4 had hypergonadotropic hypogonadism, and 1 had fibroadenosis, but in majority (90.4%), no apparent cause for breast enlargement was evident. In the idiopathic group, majority were obese (63%). Fourteen (16%) patients had impaired fasting glucose or impaired glucose tolerance. Another twenty patients had subtle abnormalities (high 1 h glucose or glucose peak at 2 h). Twenty-nine percent of lean and 38% of obese patients had mild abnormalities in glucose profile. Sixty percent of patients had family background of diabetes. Obese patients had lower testosterone as compared to lean patients; however, estradiol, luteinizing hormone, and follicle-stimulating hormone levels were similar in the two groups. Conclusion: Gynecomastia during adolescence is associated with obesity, dysglycemia, and family background of diabetes mellitus.

A 2016 clinical practice pattern in the management of primary hypothyroidism among doctors from different clinical specialties in New Delhi Highly accessed article p. 165
Vineet Surana, Sameer Aggarwal, Deepak Khandelwal, Rajiv Singla, Saptarshi Bhattacharya, Sachin Chittawar, Sanjay Kalra, Deep Dutta, Society for Promotion of Education in Endocrinology and Diabetes Group
Background: This study aimed to document practices in managing hypothyroidism among doctors in New Delhi, with special focus on subclinical hypothyroidism, pregnancy, and old age, and to compare it with global practices. Methods: During an academic program attended by 394 doctors, all participants were given a questionnaire designed based on thyroid practices survey done by Burch et al. to evaluate the practice patterns. Questions were based on evaluating doctor's preferred choices in diagnosis, therapy, and follow-up of hypothyroidism in different scenarios. Results: Responses from 308 questionnaires (general physicians [n = 204], obstetricians [n = 51], pediatricians [n = 27], surgeons [n = 12], endocrinologists [n = 10], and others [n = 4]) were analyzed. In the evaluation of 52-year-old female patient with primary hypothyroidism, 52% doctors would prefer thyroid ultrasonography, comparable to global rates. Nearly 96.1% doctors would have initiated levothyroxine, with a large majority of doctors (83.77%) preferred using branded levothyroxine. About 58.74% doctors preferred gradual restoration of euthyroidism. Levothyroxine dose of 25 mcg was the most preferred increment dose (46.07%) during follow-up, with 6 weekly being the most frequent dose adjustment frequency (41.57%). Most preferred target thyroid-stimulating hormone (TSH) in the 52-year-old female patient was 2.5–4.99 mU/L (63.96%), 25-year-old female patient was 1–2.49 mU/L (53.90%), and in 85-year-old female was 2.5–4.99 mU/L (45.45%). Only 68% of doctors in our study preferred keeping TSH <2.5 mU/L during the first trimester of pregnancy, in contrast to global trends of 95% (P < 0.001). Conclusion: There was a disproportionately high use of ultrasonography in hypothyroidism management, near exclusive preference for branded levothyroxine, widespread use of age-specific TSH targets, and low threshold for treating mild thyroid failure, a highly variable approach to both rates and means of restoring euthyroidism for overt primary hypothyroidism. There is a need for spreading awareness regarding TSH targets in pregnancy.

Balaji Bhavadharini, Manni Mohanraj Mahalakshmi, Mohan Deepa, Ranjani Harish, Belma Malanda, Arivudainambi Kayal, Anne Belton, Ponnusamy Saravanan, Unnikrishnan Ranjit, Ram Uma, Ranjit Mohan Anjana, Viswanathan Mohan
Aim: The aim of this study was to determine the optimal glycated hemoglobin (HbA1c) cut point for diagnosis of gestational diabetes mellitus (GDM) and to evaluate the usefulness of HbA1c as a prognostic indicator for adverse pregnancy outcomes. Methods: HbA1c estimations were carried out in 1459 pregnant women attending antenatal care centers in urban and rural Tamil Nadu in South India. An oral glucose tolerance test was carried out using 75 g anhydrous glucose, and GDM was diagnosed using the International Association of the Diabetes and Pregnancy Study Groups criteria. Results: GDM was diagnosed in 195 women. Receiver operating curves showed a HbA1c cut point of ≥ 5.0% (≥31 mmol/mol) have a sensitivity of 66.2% and specificity of 56.2% for identifying GDM (area under the curve 0.679, confidence interval [CI]: 0.655–0.703). Women with HbA1c ≥ 5.0% (≥31 mmol/mol) were significantly older and had higher body mass index, greater history of previous GDM, and a higher prevalence of macrosomia compared to women with HbA1c < 5.0% (<31 mmol/mol). The adjusted odds ratio for macrosomia in those with HbA1c ≥ 5.0% (≥31 mmol/mol) was 1.92 (CI: 1.24–2.97, P = 0.003). However, other pregnancy outcomes were not significantly different. Conclusion: In Asian Indian pregnant women, a HbA1c of 5.0% (31 mmol/mol) or greater is associated with increased risk of macrosomia.

Association of dental and skeletal fluorosis with calcium intake and serum vitamin D concentration in adolescents from a region endemic for fluorosis p. 190
Prerna P Patel, Pinal A Patel, M Mughal Zulf, Bhrugu Yagnik, Neha Kajale, Rubina Mandlik, Vaman Khadilkar, Shashi A Chiplonkar, Supriya Phanse, Vivek Patwardhan, Priscilla Joshi, Ashish Patel, Anuradha V Khadilkar
Context: Fluorosis is controlled by the duration of fluoride exposure and calcium and Vitamin D nutrition status. Aim: To examine (a) prevalence of dental and skeletal fluorosis in adolescents from upper, middle, and lower socioeconomic strata (SES) and (b) association of fluorosis with calcium intake and Vitamin D status. Settings and Design: A cross-sectional study conducted in 10–13.9 years apparently healthy adolescents (n = 90), from different SES of Patan (Gujarat, India). Materials and Methods: Dental fluorosis was graded as mild, moderate, and severe. Radiographs of the right hand and wrist were examined and graded. Serum 25 hydroxyvitamin D3 (25OHD) and parathyroid hormone concentrations were measured. Diet was recorded (24 h recall) and calcium intake was computed (C-diet V-2.1, 2013, Xenios Technologies Pvt. Ltd). Statistical Analysis: Generalized linear model was used to analyze relationships between fluorosis, SES, serum 25OHD concentration, and calcium intake. Results: Fluorosis was predominant in lower SES (17% had both dental and radiological features whereas 73% had dental fluorosis); no skeletal deformities were observed. Mean 25OHD concentrations and dietary calcium were 26.3 ± 4.9, 23.4 ± 4.7, and 18.6 ± 4 ng/ml and 441.2 ± 227.6, 484.3 ± 160.9, and 749.2 ± 245.4 mg/day, respectively, for lower, middle, and upper SES (P < 0.05). Fluorosis and SES showed a significant association (exponential β = 2.5, P = 0.01) as compared to upper SES, middle SES adolescents were at 1.3 times while lower SES adolescents were at 2.5 times higher risk. Serum 25OHD concentrations (P = 0.937) and dietary calcium intake (P = 0.825) did not show a significant association with fluorosis. Conclusion: Fluorosis was more common in lower SES adolescents, probably due to the lack of access to bottled water. Relatively adequate calcium intake and serum 25OHD concentrations may have increased the efficiency of dietary calcium absorption, thus preventing severe fluorosis.

A review of clinical efficacy and safety of canagliflozin 300 mg in the management of patients with type 2 diabetes mellitus Highly accessed article p. 196
KM Prasanna Kumar, Sujoy Ghosh, William Canovatchel, Nishant Garodia, Sujith Rajashekar
Currently available antihyperglycemic agents, despite being effective, provide inadequate glycemic control and/or are associated with side effects or nonadherence. Canagliflozin, a widely used orally active inhibitor of sodium-glucose cotransporter 2 (SGLT2), is a new addition to the therapeutic armamentarium of glucose-lowering drugs. This review summarizes findings from different clinical and observational studies of canagliflozin 300 mg in patients with type 2 diabetes mellitus (T2DM). By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose, thereby increasing urinary glucose excretion in patients with T2DM. Canagliflozin 300 mg has been shown to be effective in lowering glycated hemoglobin, fasting plasma glucose, and postprandial glucose in patients with T2DM. Canagliflozin 300 mg also demonstrated significant reductions in body weight and blood pressure and has a low risk of causing hypoglycemia, when not used in conjunction with insulin and insulin secretagogues. Canagliflozin 300 mg was generally well tolerated in clinical studies. The most frequently reported adverse events include genital mycotic infections, urinary tract infections, osmotic diuresis, and volume depletion-related events.

Diabetes prevalence shows a continuous increasing trend in South Asia. Although well-established treatment modalities exist for type 2 diabetes mellitus (T2DM) management, they are limited by their side effect profile. Sodium–glucose co-transporter 2 inhibitors (SGLT2i) with their novel insulin-independent renal action provide improved glycemic control, supplemented by reduction in weight and blood pressure, and cardiovascular safety. Based on the clinical outcomes with SGLT2i in patients with T2DM, treatment strategies that make a “good clinical sense” are desirable. Considering the peculiar lifestyle, body types, dietary patterns (long duration religious fasts), and the hot climate of the South Asian population, a unanimous decision was taken to design specific, customized guidelines for T2DM treatment strategies in these regions. The panel met for a discussion three times so as to get a consensus for the guidelines, and only unanimous consensus was included. After careful consideration of the quality and strength of the available evidence, the executive summary of this consensus statement was developed based on the American Association of Clinical Endocrinologists/American College of Endocrinology protocol.

Pragmatic dietary advice for diabetes during Navratris p. 231
Lovely Gupta, Deepak Khandelwal, Rajiv Singla, Piyush Gupta, Sanjay Kalra
Navratri is one of the most common religious fasts observed among Hindus. A large number of people with diabetes follow Navratris fast irrespective of its health implications, often without proper education and medical advice. The quest for the scientific research on dietary advices for Hindu fasts including Navratris shows paucity of literature comparative to the dietary advices advocated during Ramadan. The eating and physical activity patterns during different fasts vary a lot depending up on social and cultural factors. Even eating pattern is not uniform among all persons following Navratris and is modified as per their region, local culture, and religious beliefs. Dietary advice during Navratris depends upon pattern of fasting, religious beliefs, and local sociocultural factors. In this review, efforts are made to provide pragmatic dietary advice for people with diabetes, modifications in the menus and cooking practices, and timings of the meals for successful blood glucose management during Navratris. This review will also help plan diet and physical activity advice for persons observing other fasts as well.

The rule of two-thirds in diabetes epidemiology p. 242
Sanjay Kalra, Banshi Saboo, Rakesh Sahay, Deepak Khandelwal, Vipin Talwar, AG Unnikrishnan
This communication hypothesises a rule of two thirds which seems to operate in Indian diabetes epidemiology. Two thirds of all persons with dysglycemia are prediabetic; two thirds of all persons with diabetes are diagnosed to have the condtion; and two thirds are diagnosed before the age of 50 years. Two thirds of people with diabetes have concomitant hypetension or dyslipidemia; two thirds do not get their HbA1c assessed; and two thirds of those who do, do not achiev target values. Yet, two thirds of people with diabetes report satisfactory psychosocial health and quality of life, and adherence to dietary therapy and medication. Only one thirds adhere to exercise and self monitoring advice, however. Two thirds of persons on oral glucose lowering drugs receive metformin; two thirds of those on insulin receive premixed insulin or twice daily isnuslin, and a similar proportion uses pens for delivery. Thus, the rule of two thirds, rather than of halves, operates in modern Indian diabetes practice.

Vascular legacy: HOPE ADVANCEs to EMPA-REG and LEADER: A Surprising similarity p. 245
Sanjay Kalra, Rakesh Sahay
Recently reported cardiovascular outcome studies on empagliflozin (EMPA-REG) and liraglutide (LEADER) have spurred interest in this field of diabetology. This commentary compares and contrasts these studies with two equally important outcome trials conducted using blood pressure lowering agents. A comparison with MICROHOPE (using ramipril) and ADVANCE (using perindopril + indapamide) blood pressure arms throws up interesting facts. The degree of blood pressure lowering, dissociation between cardiovascular and cerebrovascular benefits, and discordance between renal and retinal outcomes are surprisingly similar in these trials, conducted using disparate molecules. The time taken to achieve such benefits is similar for all drugs except empagliflozin. Such discussion helps inform rational and evidence-based choice of therapy and forms the framework for future research.

How many oral antidiabetic drugs before insulin? p. 249
Jayant Kelwade, Harsh Parekh, Vaibhav Dukle, Bipin Kumar Sethi
Worsening of glycemic control in type 2 Diabetes mellitus occur on account of declining beta cell function. This calls for up titration of the chosen drug, addition of another agent with complementary action and eventually insulin usually after 2 or three OADs. Introduction of insulin has many issues which include parenteral route of administration, cost and enhancement of hypoglycemic tendency. We propose the addition of another OAD in lieu of insulin in whom glycemic control can be achieved equally well without insulin

Introduction: Adrenal disorders could be a life-threatening emergency, hence requires immediate therapeutic management. For this awareness regarding its diagnosis, management, and treatment is prime important. Aims and Objective: To study the awareness of adrenal disorders among interns and postgraduates students of Hamidia Hospital, Bhopal. Materials and Methods: A cross-sectional questionnaire-based study was performed. Fifty-six participants, i.e., 1st, 2nd, and 3rd years postgraduate residents of general medicine (n = 14 × 3) and interns (n = 14) were included in the study. There were 12 questions on adrenal insufficiency, adrenal adenoma, congenital adrenal hyperplasia (CAH), nonclassical CAH (NCCAH), pheochromocytoma, and Conn's syndrome. One mark was awarded for each correct response. Results: In the present study, 14 (25%) participants scored < 5 marks, 33 (58.9%) scored between 6 and 9, and 9 (16.1%) scored between 10 and 12. The mean score among the participants was 6.38 ± 2.505, with a range from 2 to 11 marks. The number of correct answers by postgraduates residents of 1st year was 101, 2nd year was 95, and 3rd year was 93 and interns scored 68 out of total 168 questions in each group. Mean awareness score for residents of 1st, 2nd, 3rd years participants and interns was 7.21 ± 2.806, 6.79 ± 2.119, and 6.64 ± 2.818 and 6.63 ± 2.505, respectively. Most of the participants recorded correct responses related to diagnosis (57.7%) followed by responses related to treatment (64.3%). Answers to a question regarding how commonly is adrenal insufficiency diagnosed in medical Intensive Care Unit, none of the individuals responded correctly.Conclusion: There was a lack of awareness regarding diagnosis, management, and treatment of adrenal disorders in central India. We need to prioritize training related to these illnesses in our postgraduate teaching curriculum in practice.
