Abstract
OBJECTIVE In this study on patients with Cushing disease, post-transsphenoidal surgery (TSS), we attempt to predict the probability of remaining in remission, at least for a year and relapse after that, using Bayes' theorem and the equation of conditional probability. The number of parameters, as well as the weightage of each, is incorporated in this equation. DESIGN AND METHODS The study design was a single-centre ambispective study. Ten clinical, biochemical, radiological and histopathological parameters capable of predicting Cushing disease remission were identified. The presence or absence of each parameter was entered as binary numbers. Bayes' theorem was applied, and each patient's probability of remission and relapse was calculated. RESULTS A total of 145 patients were included in the study. ROC plot showed a cut-off value of the probability of 0.68, with a sensitivity of 82% (range 73-89%) and a specificity of 94% (range 83-99%) to predict the probability of remission. Eighty-one patients who were in remission at 1 year were followed up for relapse and 23 patients developed relapse of the disease. The Bayes' equation was able to predict relapse in only 3 out of 23 patients. CONCLUSIONS Using various parameters, remission of Cushing disease can be predicted by applying Bayes' theorem of conditional probability with a sensitivity and a specificity of 82% and 94%, respectively. This study provided an objective way of predicting remission after TSS and relapse in patients with Cushing disease giving a weightage advantage to every parameter.

Abstract
Sheehan's syndrome (SS) is a rare but well-characterized cause of hypopituitarism. Data on skeletal health is limited and on microarchitecture is lacking in SS patients. PURPOSE We aimed to explore skeletal health in SS with bone mineral density (BMD), turnover, and microarchitecture. METHODS Thirty-five patients with SS on stable replacement therapy for respective hormone deficiencies and 35 age- and BMI-matched controls were recruited. Hormonal profile and bone turnover markers (BTMs) were measured using electrochemiluminescence assay. Areal BMD and trabecular bone score were evaluated using DXA. Bone microarchitecture was assessed using a second-generation high-resolution peripheral quantitative computed tomography. RESULTS The mean age of the patients was 45.5 ± 9.3 years with a lag of 8.3 ± 7.2 years prior to diagnosis. Patients were on glucocorticoid (94%), levothyroxine (94%), and estrogen-progestin replacement (58%). None had received prior growth hormone (GH) replacement. BTMs (P1NP and CTX) were not significantly different between patients and controls. Osteoporosis (26% vs. 16%, p = 0.01) and osteopenia (52% vs. 39%, p = 0.007) at the lumbar spine and femoral neck (osteoporosis, 23% vs. 10%, p = 0.001; osteopenia, 58% vs. 29%, p = 0.001) were present in greater proportion in SS patients than matched controls. Bone microarchitecture analysis revealed significantly lower cortical volumetric BMD (vBMD) (p = 0.02) at the tibia, with relative preservation of the other parameters. CONCLUSION Low areal BMD (aBMD) is highly prevalent in SS as compared to age- and BMI-matched controls. However, there were no significant differences in bone microarchitectural measurements, except for tibial cortical vBMD, which was lower in adequately treated SS patients.

Abstract
ABSTRACT Peptide receptor radionuclide therapy (PRRT) has shown to be effective and safe in metastatic gastroenteropancreatic and nongastroenteropancreatic neuroendocrine tumors. However, the selection criteria for PRRT are restricted to patients with good performance status (Eastern Cooperative Oncology Group score ≤2 or Karnofsky performance score ≥60). This denies many patients with adequate somatostatin receptor expression and biochemical profiles from the beneficial effects of PRRT on the quality of life, daily function, and overall survival. The 2 cases highlight the favorable response of PRRT in patients with metastatic neuroendocrine tumor having a very poor performance status initially.

Abstract
AIMS The use of Continuous Glucose Monitoring System (CGMS) improves glycemic parameters in Type 1 Diabetes Mellitus (T1D), but the cost is prohibitive. Here, we investigated the effect of short-term application of real-time and intermittently-scanned CGMS (rt and is-CGMS) in T1D individuals on change in HbA1c at the end of 3 months. METHODS T1D individuals were randomized into three groups in a ratio of 1:1:2 - Group A (rt-CGMS for 2 weeks initially, followed by is-CGMS for 2 weeks at 3 months), Group B (is-CGMS for 2 weeks initially followed by rt-CGMS for 2 weeks at 3 months) and Group C (only self-monitoring of blood glucose), respectively. HbA1c at baseline, 3, and 6 months were compared. RESULTS Out of a total 68 T1D patients, HbA1c decreased significantly in groups A and B at 6 months compared to the baseline, but not in group C. HbA1c was significantly lower in Group A compared to Group C at 3 and 6 months. Fructosamine levels significantly decreased in Group B before and after cross-over. Glycemic variability indices improved significantly after cross-over from is-CGMS to rt-CGMS. CONCLUSION Intermittent application of CGMS for 2 weeks improves short- and long-term blood glucose control in T1D.

Abstract
OBJECTIVE Apart from renal stones, primary hyperparathyroidism (PHPT) has been linked to the occurrence of gallstone disease (GSD). Nevertheless, the association is not consistent across all studies. The present systematic review and meta-analysis aims to collate the hitherto available evidence and provide a pooled estimate of the association between GSD and PHPT. METHODS PubMed/MEDLINE, Embase, and Web of Science databases were systematically searched from inception till May 10, 2023 for observational studies reporting the prevalence of GSD (in terms of absolute numbers) in patients with PHPT. The pooled prevalence of GSD and odds ratio with 95% CI of the occurrence of GSD in patients with PHPT as compared to age- and sex-matched controls were calculated. Subgroup analysis was performed based on patient ethnicity (Indian/Caucasian). Statistical analysis was carried out using R version 4.2.2. Random-effects model with Hartung-Knapp adjustment was used for analyses. RESULTS A total of 7 observational studies were included, pooling data from 15 949 patients with PHPT. The pooled prevalence of GSD in patients with PHPT was 16% (95% CI: 7%, 25%, I2 = 99%), being 13% (95% CI: 0%, 66%, I2 = 76%) in Indians, and 17% (95% CI: 4%, 31%, I2 = 99%) in Caucasians. Data consolidated from 3 studies showed that the pooled odds ratio of occurrence of GSD in patients with PHPT compared to controls was 1.77 (95% CI: 1.60, 1.97, P < .001, I2 = 0%). CONCLUSIONS GSD is more prevalent in patients with PHPT than in the general population. Thus, PHPT may be considered an additional risk factor for GSD.

Abstract
Primary hyperparathyroidism (PHPT) is a systemic disease that affects all the systems of the body, specifically the bones and the kidneys. Its main action is on calcium homeostasis. It tries to preserve the body's calcium level at the cost of phosphate. The criteria for surgery in asymptomatic PHPT patients revolve around raised serum calcium levels, renal dysfunction or nephrolithiasis, and bone health. It does not take into account the serum phosphate levels. Depending on the serum level, Hypophosphatemia is divided into mild, moderate, and severe categories. In PHPT, several studies have suggested that asymptomatic PHPT patients with moderate hypophosphatemia may warrant surgical intervention. Treatment of hypophosphatemia in PHPT is based upon the degree of hypophosphatemia, and treatment is given according to that oral or intravenous route; after surgical and medical treatment of PHPT, phosphate levels gradually normalized. But even after these considerations, phosphate levels in PHPT are not given much importance.

Abstract
BACKGROUND Strain echocardiography is a highly sensitive modality for detecting myocardial disease at an early stage. Therefore, we aim to evaluate subclinical left ventricular dysfunction in primary hyperparathyroidism (PHPT) patients with myocardial strain imaging in addition to conventional echocardiography and to look for its reversal after parathyroidectomy (PTx). METHODS Thirty patients who underwent curative parathyroidectomy for PHPT were included. All patients were evaluated with M mode echo, 2D echo and strain imaging before and 6 months after PTx. Left ventricular ejection fraction, left ventricular diastolic dysfunction, left ventricular hypertrophy (LVH), Global Longitudinal Strain (GLS) and global circumferential strain (GCS) were recorded. RESULTS On M mode echo, LVH was present in 15 patients and 8 of them improved completely after PTx (p < 0.038). Incidence of systolic and diastolic dysfunction on 2D echo was 10% and 13.3% respectively; while myocardial strain imaging showed impaired systolic function in 46.7% patients. Hence, compared to conventional 2D echo, strain imaging showed 36.7% high detection rate of subnormal cardiac function. There was improvement in left ventricle dysfunction (p = 0.083), GLS and GCS (p = 0.034) after PTx. Serum parathormone demonstrated a strong positive correlation with change in GLS and GCS (p = 0.013, p = 0.126) while serum calcium showed a weak correlation with change in GLS and GCS following surgery. CONCLUSION Myocardial strain imaging should be considered for all PHPT patients as early identification of subclinical ventricle dysfunction provides an opportunity for an early intervention and thereby preventing development of irreversible LV dysfunction.

Abstract
Neuroendocrine tumors (NETs) may mimic many endocrine syndromes, including Cushing syndrome (CS) secondary to ectopic ACTH secretion. Radiotherapy (RT) is often used as adjuvant therapy for such persistent or recurrent NETs. However, RT may predispose a susceptible person to a second malignancy. Here, we reported the story of a 37-year-old male, who presented with progressive weight loss, bone pain, and shortness of breath in the emergency department. He was diagnosed with CS secondary to a carcinoid tumor in the bronchopulmonary tree a decade previous and underwent total bilateral adrenalectomy. He also underwent lobectomy, and subsequent RT for a primary NET and was in clinical remission. His presenting symptoms were considered a recurrence of pulmonary NETs. However, the biopsy suggested high-grade mucoepidermoid carcinoma (MEC). MEC of the lung is a rare tumor with a prevalence of <1% of all lung malignancies. MEC of the lung after RT for bronchial NET-causing ectopic CS has not yet been reported in the literature. The present patient did not survive despite achieving remission of CS and primary tumor because of the aggressive second malignancy attributed to RT, which was given for the primary tumor.

Abstract
INTRODUCTION Patients with ulcerative colitis (UC) are likely to have poor nutritional intake and increased gut losses. This study was designed to study the prevalence and predictors of nutritional deficiencies in patients with UC and their impact on the quality of life (QOL). METHODS A prospective study was conducted among consenting patients with UC (cases) and healthy relatives of the cases (controls) visiting a university teaching hospital. They were assessed for clinical, demographic, endoscopic (Mayo score) and histological profile (Robart's score). They were assessed for the presence of macronutrient and micronutrient deficiency, anthropometry, functional status (muscle strength by dynamometer and sit-to-stand test) and the quality of life (short inflammatory bowel disease questionnaire [SIBDQ]). A SIBDQ score of ≤ 50 was considered poor QOL. RESULTS We studied 126 cases and 57 healthy controls (age [mean ± SD] 37.7 ± 13.2 years vs. 34.40 ± 11.05 years; [p = 0.10] females [38.1% vs. 38.7%]; p = 0.94). Cases more often were underweight (28% vs. 3.5%; p < 0.001), had low mid arm circumference (45% vs. 12%; p < 0.0001), lower functional status in the form of weaker hand grip strength (67% vs. 45.6%; p = 0.007) and weaker lower limb strength (80% vs. 42%; p < 0.0001). Cases more often had the evidence of macronutrient deficiencies: total serum protein deficiency (31% vs. 3.5%; p < 0.0001), serum albumin deficiency (25.4% vs. 0.00%; p < 0.0001) and cholesterol deficiency (63% vs. 28%; p < 0.0001). Micronutrient deficiencies were highly prevalent among cases: calcium (44%), phosphate (21%), magnesium (11%), zinc (76%), iron (87%), folate (16%), vitamin B12 (10%) and vitamin D (81%). Most cases had a poor quality of life (85/126; 67.5%). Factors associated with poor QOL were low hemoglobin, serum albumin, zinc and vitamin D levels and histologically active disease. On multi-variate analysis, low vitamin D levels (odds ratio [OR] = 6.1; 95% confidence interval [CI]: 1.9-19.7) and histologically active disease (OR = 4.0; 95% CI: 1.6-9.9) were identified as independent predictors of poor QOL. CONCLUSIONS Macronutrient deficiency, micronutrient deficiency, lower functional status and poorer QOL are highly prevalent among patients with UC. The independent predictors of poor QOL were histologically active disease and low serum vitamin D levels. Identifying and correcting the deficiencies may help in improving the QOL of patients with UC.

Abstract
Introduction Medullary thyroid carcinoma (MTC) is a rare thyroid malignancy originating from parafollicular C cells. It accounts for 5%-10% of all thyroid malignancies. Methods An ambispective analysis of pathologically proven MTC presented in a tertiary care hospital in northwest India was performed after considering demography, clinical manifestation, RET mutation status, management, and outcome as denominators. Results Among 2,735 thyroid malignancy cases who presented to our institute in the last 10 years (2012-2022), 78 (3%) had MTC with a mean age of presentation of 43 ± 11 years; 60% of them were female. The median duration of symptoms was 23 months (IQR 12-36 months). The most common presenting complaint was goiter with lymphadenopathy (80.8%). Among the atypical presentations, one each had ectopic Cushing's syndrome, hypertensive crisis in pregnancy due to pheochromocytoma, synchronous chondrosarcoma, and Von Hippel-Lindau disease spectrum. Median calcitonin and carcinoembryonic antigen (CEA) levels at presentation were 1,274 pg/mL (n = 64) and 149 ng/mL (n = 39), respectively. Twenty-two patients were germline RET mutation-positive, and they presented at a younger age. Majority of the patients presented with stage IV disease. Surgery was the primary modality of therapy. Twenty-nine patients received radiotherapy and 25 patients received tyrosine kinase inhibitors (TKIs). Nine patients received peptide receptor radiotherapy (PRRT) with Lu-177 with neoadjuvant capecitabine. Median progression-free survival (PFS) was 60 months. Patients without structurally and biochemically residual disease and stable disease after the first modality of therapy (Log-rank 11.4; p = 0.004) had a better PFS. Female patients (Log-rank: 9.5; p = 0.002) had a better PFS than male patients. Conclusion This study showed that MTC comprises 3% of thyroid malignancies with a female preponderance. RET mutation-positive patients had a younger age at presentation. Surgery was the first-line therapy. Radiotherapy, TKI, and PRRT were given as a part of second-line or third-line therapy due to persistent disease and/or disease recurrence. The median PFS was better in female patients and in patients who had no residual lesions and stable disease after the primary modality of therapy.

Abstract
PURPOSE To assess the utility of pre-defined imaging biomarkers on optical coherence tomography (OCT) and OCT angiography (OCTA) in patients with diabetic macular edema (DME) following anti-vascular endothelial growth factor (anti-VEGF) therapy in determining visual and anatomical outcomes. METHODS In this prospective, non-randomized, and interventional study, 17 patients with treatment-naive DME were included. OCT biomarkers [size/reflectivity of cysts, disorganization of retinal inner layers, integrity of ellipsoid zone or external limiting membrane, subfoveal serous retinal detachment, hyper-reflective foci (HRF)] and OCTA [vascular density (VD), foveal avascular zone (FAZ), and total micro-aneurysms in superficial capillary plexus and deep capillary plexus (DCP)] were analyzed at baseline and after three monthly intravitreal anti-VEGF injections. Response was defined as a decrease of 10% or more in central macular thickness from the baseline after three injections. RESULTS 13/17 (76.47%) patients were categorized as responders to anti-VEGF therapy. Non-responders had significantly greater hyper-reflectivity of cysts (P = 0.015), larger cystic spaces (P = 0.023), and an increased number of HRF (P = 0.04) at baseline. On OCTA, non-responders showed larger FAZ in DCP (1.35 ± 0.21 versus 1.14 ± 0.28 mm2) (P = 0.042) and lower VD (61.17 ± 0.45 versus 62.73 ± 3.32) in DCP at baseline. At 3 months, the VD increased in responders (63.10 ± 3.42) compared to a decrease in non-responders (60.82 ± 1.13) (P = 0.032). CONCLUSIONS Non-responders show a higher number of micro-aneurysms, larger FAZ, and lower VD in the DCP on OCTA and higher cyst hyper-reflectivity and HRF and larger cystic spaces on OCT imaging.

Abstract
In this study, the role of inelastic deformation of bone on its strain rate-dependent mechanical behaviour was investigated. For this, human cortical bone samples were cyclically loaded to accumulate inelastic strain and subsequently, mechanical response was investigated under compressive loading at different strain rates. The strain rate behaviour of fatigued samples was compared with non-loaded control samples. Furthermore, cyclic loading-induced microdamage was quantified through histological analysis. The compression test results show that the strength of fatigue-loaded bone reduced significantly at low strain rates but not at high strain rates. The difference in microcrack density was not significant between fatigued and control groups. The results indicate that the mechanism of load transfer varies between low strain rate and high strain rate regimes. The inelastic deformation mechanisms are more prominent at low strain rates but not at high strain rates. This study shed light on the role of inelastic deformation on the rate-dependent behaviour of cortical bone.

Abstract
Bone fragility is an emerging complication of diabetes. People with diabetes are at a significantly higher risk of fractures compared to the general population. Bone fragility occurs in diabetes as a result of complex and poorly understood mechanisms occurring at the cellular level contributed by vascular, inflammatory and mechanical derangements. Bone mineral density (BMD) as assessed by DEXA is low in type 1 diabetes. Type 2 diabetes has a high risk of fracture despite a normal to raised BMD. DEXA thus underestimates the fracture risk in diabetes. Data are scare regarding the efficacy of the available therapies in this low bone turnover state.

Abstract
Introduction This article concisely overviews the complex relationship between obesity and bone health. Obesity, characterized by excessive fat accumulation, has been traditionally associated with higher bone mineral density. Also, recent data suggest a favorable bone microarchitecture profile in these patients. However, the increase in bone mineral density does not necessarily confer protection against fractures, and the risk of fractures may vary depending on the skeletal sites. Factors affecting bone health Various factors, including mechanical factors, hormones, cytokines, inflammation, and bone marrow adiposity, contribute to the adverse effect of obesity on bone. The article explores these factors alongside non-invasive techniques and tools like the Fracture Risk Assessment (FRAX) to evaluate fracture risk. Bone and Adipose tissue This article also highlights the essential roles of hormones such as vitamin D, Parathormone (PTH), FGF-23 (Fibroblast Growth Factor 23), which affect bone health, and some of the hormones secreted from the adipose tissues such as adiponectin and leptin. Obesity Paradox and Sarcopenic Obesity The article delves into the intriguing obesity paradox, where an increased BMI correlates with higher bone mineral density but not necessarily reduced fracture risk. Sarcopenic obesity, a combination of excessive fat accumulation and reduced muscle mass, further complicates the relationship between obesity and bone health. Conclusions Physicians should keep a comprehensive approach to treating obese patients with osteoporosis, including lifestyle modifications, weight management, fall prevention strategies, and pharmacological interventions. Further research is needed to better understand the relationship between obesity and bone health.

Abstract
Background Bisphosphonates, synthetic analogs of endogenous pyrophosphates, are pivotal in managing various bone disorders, primarily osteoporosis, which affects millions globally. While osteoporosis, especially postmenopausal osteoporosis, significantly benefits from bisphosphonate therapy, considerations arise regarding their administration and potential side effects. Clinical application of Bisphosphonates Bisphosphonates, divided into nitrogen-containing and non-nitrogenous groups, exert their influence through distinct mechanisms, with the former being notably more potent. The role of bisphosphonates in other diseases, such as Paget's bone and skeletal metastasis disease is also discussed. Detailed information on the administration routes, dosage regimens, and considerations for drug holidays is provided. The article navigates through the chemical structure, generations, and mechanism of action of bisphosphonates. The article covers administration routes, dosage regimens, and drug holidays, in addition to discussing potential adverse effects and contraindications. Conclusions Bisphosphonates hold an unrivaled legacy in the management of osteoporosis. The ubiquitous availability and the cost-effectiveness of these time-tested medications make them an invaluable asset in the osteoporosis treatment landscape, especially in developing nations like India.

Abstract
OBJECTIVES Lipids and micronutrients play a major role in the pathophysiology of diabetes, and several studies have established the association between lipids and diabetes. The aim of this study was to determine the interaction between lipid profile and micronutrient status with different prediabetes and diabetes diagnosis criteria among school-aged children in India. METHODS The data used in this study was from Comprehensive National Nutritional Survey conducted in India from 2016 to 2018. Glycosylated hemoglobin values and fasting blood glucose were used to classify normal, prediabetes, and diabetes. The interaction analysis between the lipid profile and eight micronutrients was conducted using multiple logistic regression analyses, and the predicted probabilities were determined. RESULTS Among micronutrients, the highest deficiency was observed for hemoglobin (27%), and in the lipid profile, triacylglycerol was high in 34% of children. The interaction between high total cholesterol and vitamin B12 deficiency showed the highest average probability for prediabetes (66%). The highest average probability for diabetes was observed from the interaction between normal high-density lipoprotein and vitamin A deficiency (3%). CONCLUSION The interaction between micronutrients and lipids suggests complex multidimensional pathways involving folate, vitamin B12, ferritin, zinc, hemoglobin, and iodine deficiencies. These interactions should be considered when planning diabetes management strategies.

Abstract
Objective To derive a clinical score from parameters that favor remission of Cushing's disease (CD) after pituitary surgery. Methods This is an analysis of 11 clinical, hormonal, and post-operative parameters that each favored remission in a cohort of 145 patients with CD treated by trans-sphenoidal surgery (TSS). Each parameter was designated as a categorical variable (presence/absence), and several favorable parameters present for each patient were calculated. From this, a median parameter score (clinical score) of the entire cohort was derived, which was then compared to the event of remission/persistence of CD. Results The median number of favorable parameters present in the entire cohort was 3 (0-7). The significant count of patients in remission increased with the increasing number of parameters. The receiver-operator characteristic curve showed that the presence of ≥3 parameters was associated with remission in CD with a sensitivity of 84.2% and a specificity of 80%. Patients with a clinical score ≥3 had significantly higher remission rates (88.9%) than those who had persistent disease (27.3%; P = 0.001). Conclusion A clinical score of ≥3 predicts remission in CD treated by TSS; however, it requires validation in other large cohorts. Rather than assessing individual parameters to predict remission in CD, an integrated clinical score is a better tool for follow-up and patient counseling.

Abstract
Background People with type 2 diabetes (T2D) are at high risk of fragility fractures; however, there are no randomized controlled trials evaluating the efficacy of anti-osteoporosis drugs as a primary pre-specified endpoint in T2D. Objectives To compare the efficacy of anti-osteoporotic drugs in postmenopausal women with T2D. Design Prospective, randomized, open, blinded endpoint clinical pilot trial. Methods Postmenopausal women (⩾50 years) with T2D (duration ⩾5 years), HbA1c 7-10%, eGFR ⩾45 mL/min/1.73 m2 and prior vertebral (clinical/morphometric), hip, radius, humeral fragility fracture or bone mineral density (BMD) T-score (adjusted for diabetes) at lumbar spine/femoral neck ⩽-2.5 and high FRAX score will be eligible for inclusion. Subjects with secondary causes of osteoporosis, prior exposure to bone-active therapies or history of use of glucocorticoids/pioglitazone/thiazides/canagliflozin will be excluded. Finally, eligible subjects will undergo estimation of serum calcium, phosphate, alkaline phosphatase, parathyroid hormone, 25-hydroxyvitamin D and bone turnover markers (BTMs) (total procollagen type I N-propeptide, β-CTX) along with trabecular bone score (TBS) and high-resolution peripheral quantitative computed tomography (HR-pQCT) of non-dominant hand and leg. After a 2-week run in phase, they will be randomized in a 1:1:1:1 ratio to receive yearly zoledronate, or biannually denosumab or daily teriparatide (in addition to standard of care, i.e., calcium 1000 mg/day and cholecalciferol 1000 IU/day) or only standard of care (control). The primary endpoints will be change in areal BMD and frequency of incident fractures at 18 months. The secondary endpoints will be change in HR-pQCT parameters, TBS and BTMs at 18 months. Adverse events will be recorded for all randomized participants. Ethics The study has been approved by the Institute Ethics Committee. Written informed consent will be obtained from each participant. Discussion The trial is expected to provide information regarding optimal anti-osteoporotic therapy in people with T2D and bone fragility. Registration Prospectively registered in Clinical Trial Registry of India (CTRI/2022/02/039978).

Abstract
A 26-year-old male presented with facial asymmetry since 11 years of age and painless progressive diminution of vision in the left eye since 16 years of age. He presented with an exacerbation of headaches for the past two months. On examination, he was tall and had acral enlargement, craniofacial deformity, and bilateral asymmetric testicular enlargement. Investigations revealed high insulin-like growth factor 1, non-suppressible growth hormone on oral glucose tolerance tests, and multiple pituitary hormone deficiencies. MRI showed pituitary macroadenoma with craniofacial and sphenoid fibrous dysplasia as well as multiple tuberculomas. Cerebrospinal fluid testing showed high protein, low glucose, and high adenosine deaminase, all consistent with a diagnosis of central nervous system (CNS) tuberculosis. His headache did not respond significantly to either octreotide or zoledronic acid. The patient was then initiated on antitubercular therapy, which led to near-complete resolution of the headache and CNS lesions within three months of therapy. CNS tuberculosis was a masquerader in the index case of acrogigantism due to McCune-Albright syndrome. Headaches may be multifactorial in a given case of acromegaly, and investigating for alternative or additional causes especially when dealing with treatment-refractory cases can be rewarding.

Abstract
BACKGROUND Vitamin D deficiency (VDD) is highly prevalent across the globe. Cholecalciferol (Vitamin D3) fails to attain sufficient serum concentrations of 25-hydroxyvitamin D (25(OH)D) in a significant proportion of supplemented individuals. Calcifediol (25-hydroxyvitamin D3) is less studied in healthy adults and its effects on 25(OH)D, parathyroid hormone (PTH), and 1,25-dihydroxyvitamin D (1,25(OH)2D) at higher doses are not well known. MATERIALS AND METHODS The study was an open-label, interventional trial recruiting consecutive participants with VDD who were allocated to receive either 2 capsules (50 μg-group) or 1 capsule (25 μg-group) daily doses of calcifediol. Baseline assessment included clinicodemographic parameters, dietary calcium, calcemic (calcium, inorganic phosphate, albumin, alkaline phosphatase, urine spot calcium/creatinine), and hormonal parameters (25(OH)D, PTH, and 1,25(OH)2D). Participants were followed up at 4 and 8 weeks with repeat assessments of calcemic and hormonal parameters. RESULTS There were 64 participants, 35 (50 μg-group) and 29 (25 μg-group), without any significant difference in any of the baseline parameters. 97.1% participants in the 50 μg-group (at 4 and 8 weeks) and 93.1% (at 4 weeks) and 96.5% (at 8 weeks) in the 25 μg-group attained 25(OH)D sufficiency (≥30 ng/ml) with calcifediol. The mean serum 25(OH)D was 84.0 ± 27.7 ng/ml in the 50 μg-group and 58.0 ± 23.6 ng/ml in the 25 μg-group group at 4 weeks, which later rose to 94.3 ± 21.8 ng/ml and 76.0 ± 16.4 ng/ml, respectively, at 8 weeks. PTH levels decreased in both groups at both time points. 1,25(OH)2D rose significantly in both groups at 4 and 8 weeks but was not significantly different between both groups. There was no case of incident hypercalcemia or symptomatic nephrolithiasis. CONCLUSION Calcifediol is a safe and efficacious alternative for oral Vitamin D supplementation in young adults. Increment in 25(OH)D levels is rapid and dose-dependent.

Abstract
The occurrence of diabetes mellitus (DM) in pancreatitis is being increasingly recognized lately. Diabetes can develop not only with chronic pancreatitis but even after the first episode of acute pancreatitis (AP). The incidence of diabetes after AP varies from 18% to 23% in 3 years and reaches up to 40% over 5 years. The exact pathogenesis of diabetes after AP is poorly understood and various mechanisms proposed include loss of islet cell mass, AP-induced autoimmunity, and alterations in the insulin incretin axis. Risk factors associated with increased risk of diabetes includes male sex, recurrent attacks of pancreatitis, presence of pancreatic exocrine insufficiency and level of pancreatitic necrosis. Diagnosis of post-pancreatitis DM (PPDM) is often excluded. Treatment includes a trial of oral antidiabetic drugs in mild diabetes. Often, insulin is required in uncontrolled diabetes. Given the lack of awareness of this metabolic disorder after AP, this review will evaluate current information on epidemiology, risk factors, diagnosis and management of PPDM and identify the knowledge gaps.

Abstract
The gut microbiome influences the pathogenesis and course of metabolic disorders such as diabetes. While it is likely that duodenal mucosa associated microbiota contributes to the genesis and progression of increased blood sugar, including the pre-diabetic stage, it is much less studied than stool. We investigated paired stool and duodenal microbiota in subjects with hyperglycemia (HbA1c ≥ 5.7% and fasting plasma glucose > 100 mg/dl) compared to normoglycemic. We found patients with hyperglycemia (n = 33) had higher duodenal bacterial count (p = 0.008), increased pathobionts and reduction in beneficial flora compared to normoglycemic (n = 21). The microenvironment of duodenum was assessed by measuring oxygen saturation using T-Stat, serum inflammatory markers and zonulin for gut permeability. We observed that bacterial overload was correlated with increased serum zonulin (p = 0.061) and higher TNF-α (p = 0.054). Moreover, reduced oxygen saturation (p = 0.021) and a systemic proinflammatory state [increased total leukocyte count (p = 0.031) and reduced IL-10 (p = 0.015)] characterized the duodenum of hyperglycemic. Unlike stool flora, the variability in duodenal bacterial profile was associated with glycemic status and was predicted by bioinformatic analysis to adversely affect nutrient metabolism. Our findings offer new understanding of the compositional changes in the small intestine bacteria by identifying duodenal dysbiosis and altered local metabolism as potentially early events in hyperglycemia.

Abstract
Protein-protein interactions (PPIs) play a critical role in all biological processes. Menin is tumor suppressor protein, mutated in multiple endocrine neoplasia type 1 syndrome and has been shown to interact with multiple transcription factors including (RPA2) subunit of replication protein A (RPA). RPA2, heterotrimeric protein required for DNA repair, recombination and replication. However, it's still remains unclear the specific amino acid residues that have been involved in Menin-RPA2 interaction. Thus, accurately predicting the specific amino acid involved in interaction and effects of MEN1 mutations on biological systems is of great interests. The experimental approaches for identifying amino acids in menin-RPA2 interactions are expensive, time-consuming, and challenging. This study leverages computational tools, free energy decomposition and configurational entropy scheme to annotate the menin-RPA2 interaction and effect on menin point mutation, thereby proposing a viable model of menin-RPA2 interaction. The menin-RPA2 interaction pattern was calculated on the basis of different 3D structures of menin and RPA2 complexes, constructed using homology modeling and docking strategy, generating three best-fit models: Model 8 (- 74.89 kJ/mol), Model 28 (- 92.04 kJ/mol) and Model 9 (- 100.4 kJ/mol). The molecular dynamic (MD) was performed for 200 ns and binding free energies and energy decomposition analysis were calculated using Molecular Mechanics Poisson-Boltzmann Surface Area (MM/PBSA) in GROMACS. From binding free energy change, model 8 of Menin-RPA2 exhibited most negative binding energy of - 205.624 kJ/mol, followed by model 28 of Menin-RPA2 with - 177.382 kJ/mol. After S606F point mutation in Menin, increase of BFE (ΔGbind) by - 34.09 kJ/mol in Model 8 of mutant Menin-RPA2 occurs. Interestingly, we found a significant reduction of BFE (ΔGbind) and configurational entropy by - 97.54 kJ/mol and - 2618 kJ/mol in mutant model 28 as compared the o wild type. Collectively, this is the first study to highlight the configurational entropy of protein-protein interactions thereby strengthening the prediction of two significant important interaction sites in menin for the binding of RPA2. These predicted sites could be vulnerable for structural alternation in terms of binding free energy and configurational entropy after missense mutation in menin.

Abstract
The continuous cell line of epithelial human parathyroid cells has been proven difficult. Previously, PTH-C1 cell line was only established rat parathyroid tissue cell line known to express the parathyroid hormone-related peptide (Pthrp) gene. The paucity of continuous cell line of human parathyroid cells secreting parathyroid hormone (PTH) has imposed hurdle in in vitro assessment of the mechanisms involved in the control of parathyroid cell function and proliferation. The primary cell cultures of human parathyroid cells were derived from parathyroid adenoma tissue biopsy (n = 5). The cells were subsequently subcultured to maintained primary subclones. Karyotyping analysis was performed to analyze the genotypic identity of derived subclones. The expression of calcium-sensing receptor (CaSR) and intact parathyroid hormone (iPTH) were analyzed using immunocytochemistry and immunofluorescence. In the present study, we have used a defined condition medium to generate the continuous culture of human parathyroid cells derived from patients with parathyroid adenoma due to primary hyperparathyroidism. The subcultured primary subclones were maintained epithelial and polygonal morphology, doubling time of approximately 25 h, displaying a diploid chromosome number, and secretion of PTH. This cell line produces PTH and expresses the calcium-sensing receptor (CaSR) known to be involved in parathyroid function. Altogether these findings indicate the uniqueness of the human parathyroid cell line as an in vitro model for cellular and molecular studies on parathyroid physiopathology.

Abstract
BACKGROUND It has been a matter of debate for long time about the existence of two distinct phenotypes of primary hyperparathyroidism (PHPT) predisposed to either renal or skeletal manifestation. OBJECTIVE To differentiate characteristics of symptomatic PHPT patients based on the presence of skeletal or renal involvement. DESIGN Retrospective analysis of data from the Indian PHPT registry. PATIENTS PHPT patients were divided into four discrete groups: asymptomatic, presenting with renal manifestations alone, skeletal manifestations alone, and both skeletal and renal manifestations. MEASUREMENTS Clinical, biochemical, and tumor weight and histopathological characteristics of these groups were compared. RESULTS Of the 229 eligible patients, 45 were asymptomatic, 62 had renal manifestations, 55 had skeletal manifestations, and 67 had both skeletal and renal manifestations. Patients with both skeletal and renal manifestations had higher serum calcium levels than those with isolated skeletal involvement [12.5 (11.1 - 13.7) mg/dl, 11.2 (10.6 - 12.3) mg/dl, respectively; p<0.05]. Serum alkaline phosphatase (AP), plasma parathyroid hormone (PTH) levels, and parathyroid tumor weight were significantly higher in patients with isolated skeletal, and both skeletal and renal manifestations, compared to the other two groups. A preoperative PTH and AP level of 300 pg/ml and 152 U/L, predicted the risk of developing skeletal involvement with sensitivity and specificity of 71%, 70%, and 69%,67%, respectively. CONCLUSIONS We observed distinct skeletal and renal phenotypic subgroups among PHPT patients with characteristic biochemical and hormonal patterns with higher parathyroid disease burden in patients with skeletal complications compared to those with isolated renal manifestation.

Abstract
Decreased bifidobacterial abundance, disrupted gut barrier function, dysregulated immune response and ulceration have been reported in the gut microbiota of IBD patients. Non-digestible carbohydrates with bifidogenic effect enrich the gut microbiota with Bifidobacterium spp. and could help in overcoming inflammatory gut conditions. In this study, the protective effect of Bifidobacterium longum Bif10 and Bifidobacterium breve Bif11; isomaltooligosaccharides (IMOS); Finger millet arabinoxylan (FM-AX) and their Synbiotic mix were evaluated against dextran sodium sulphate (DSS) induced UC in male Balb/c mice for 25 days. All the interventions ameliorated symptoms of colitis such as disease activity index (DAI), histological damage to the colon, gut-bacterial dysbiosis and inflammation. However, the synbiotic mix was more potent in amelioration of some of the parameters such as decreased TNF-α and lipocalin levels; increased anti-inflammatory markers (IL-10 and IL-22), and improved short chain fatty acids (SCFAs) levels in the cecum content. Furthermore, mouse colitis histological scoring (MCHI) also suggested the preventive role of synbiotic mix. All the dietary interventions aid in improving the DAI and immune parameters; restoration or regeneration of the altered selected gut bacteria, enhances the SCFA production, strengthens gut barrier, prevents gut inflammation and decreases the colonic MCHI score in DSS fed mice.

Abstract
PURPOSE The current study aimed to report cases of McCune Albright syndrome (MAS) with growth hormone (GH) hyper secretion along with a systematic review of literature to elucidate challenges and intricacies in its diagnosis and management. METHODS It was a single centre study carried out in individuals with MAS and autonomous GH secretion (AGHS). In addition, a systematic search of literature across three databases (PubMed, Scopus and EMBASE) was performed from inception until May 31, 2021 to identify cases of MAS with AGHS in the pediatric age group (<18 years). RESULTS Three cases from authors centre and 42 cases identified from systematic literature review were analysed. Precocious puberty was the most common presenting endocrinopathy seen in 56.8% (25/44) cases, followed by hyperthyroidism (10/45), hypophosphatemia (4/45), and hypercortisolism (2/45). Cranio-facial fibrous dysplasia (CFFD) was seen in all while polyostotic fibrous dysplasia and Café au lait macule was seen in 40/45 (88.9%) and 35/45 (77.8%), respectively. Pituitary adenoma (58.3% microadenoma) was localized in 53.3% (24/45) cases on pituitary imaging. Biochemical and clinical remission of AGHS was achieved in 61.5% (24/45) cases with medical therapy. CONCLUSION Diagnosing AGHS in MAS is challenging because of concomitant presence of CFFD, non-GH endocrinopathies associated height spurt and elevated serum IGF-1. GH-GTT should be performed in presence of elevated growth velocity and serum IGF-1 (>1 X ULN) despite adequate control of non-GH endocrinopathies. Medical management can lead to disease control in substantial number of cases and often entails use of multiple agents.

Abstract
Probiotics are known to stimulate, modulate, and regulate host immune response by regulating specific sets of genes and improve glucose homeostasis through regulating dipeptidyl peptidase (DPP-IV) activity, but the mechanism behind their protective role is not clearly understood. Therefore, the present study was designed to isolate indigenous lactic acid bacterial (LAB) strains from different fermented food samples, vegetables, and human infant feces exhibiting anti-inflammatory, antioxidant, and DPP-IV inhibitory activity. A total of thirty-six Gram-positive, catalase-negative, and rod-shaped bacteria were isolated and screened for their anti-inflammatory activity using lipopolysaccharide (LPS)-induced inflammation on the murine (RAW264.7) macrophages. Among all, sixteen strains exhibited more than 90% reduction in nitric oxide (NO) production by the LPS-treated RAW264.7 cells. Prioritized strains were characterized for their probiotic attributes as per the DBT-ICMR guidelines and showed desirable probiotic attributes in a species and strain-dependent manner. Accordingly, Lacticaseibacillus rhamnosus LAB3, Levilactobacillus brevis LAB20, Lactiplantibacillus plantarum LAB31, Pediococcus acidilactici LAB8, and Lactiplantibacillus plantarum LAB39 were prioritized. Furthermore, these strains when co-supplemented with LPS and treated on RAW264.7 cells inhibited the mitogen-activated protein kinases (MAPKs), i.e., p38 MAPK, ERK1/2, and SAPK/JNK, cyclooxygenase-2 (COX-2), relative to the LPS-alone-treated macrophages. LAB31 and LAB39 also showed 64 and 95% of DPP-IV inhibitory activity relative to the Lacticaseibacillus rhamnosus GG ATCC 53103, which was used as a reference strain in all the studies. Five prioritized strains ameliorated the LPS-induced inflammation by downregulating the JNK/MAPK pathway and could be employed as an alternative bio-therapeutic strategy in mitigating gut-associated inflammatory conditions. The potential mechanism of action of prioritized LAB strains in preventing the LPS-induced inflammation in RAW 264.7 macrophage cells.

Abstract
Background Metabolic syndrome represents aggregation of risk factors associated with an increased risk of developing type 2 diabetes mellitus (DM) and atherosclerotic cardiovascular disease (ASCVD). Assessing its incidence is an effective way for estimating the future burden of DM and ASCVD and understanding their secular trends and effect of public health measures on halting the evolution of risk factors. The present study aimed to estimate the incidence of metabolic syndrome and its predictors using a population-based cohort. Methods A subset of Chandigarh Urban Diabetes Study cohort (n = 1023) without diabetes or metabolic syndrome was prospectively evaluated after a mean of 10.7 years. Metabolic syndrome was defined as per International Diabetes Federation criteria and diabetes as per American Diabetes Association standards. The incidence was calculated in 1000 person years, and multivariate logistic regression was used to estimate the strength of association between incident metabolic syndrome and risk factors. Results In the followed-up individuals (n = 303), incidence of metabolic syndrome was 32.1 per 1000 person years (95% CI 26.3-38.7 per 1000 person years). Amongst those developing metabolic syndrome, ≥4 components were present in 52% individuals, with low HDL-C being the most common abnormality. Those with metabolic syndrome had a five-time higher risk of diabetes (OR: 4.94; 95% CI: 2.27-9.96; p < 0.001) and a threefold higher risk of hypertension (OR: 2.67; 95% CI: 1.30-5.48; p = 0.006). Conclusion Asian-Indians have a high incidence rate of metabolic syndrome, which is associated with sedentary lifestyle and consequent central obesity.

Abstract
Introduction Diabetes is a potent risk factor for the activation of latent tuberculosis and worsens the tuberculosis (TB) treatment outcome. The major reason for mortality and morbidity in diabetic patients is due to their increased susceptibility to TB. Thus, the study was conducted to understand the crosstalk between M. tuberculosis and its host upon latent tuberculosis infection and under hyperglycemic conditions or diabetes. Methods An animal model was employed to study the relationship between latent tuberculosis and diabetes. BCG immunization was done in mice before infection with M. tuberculosis, and latency was confirmed by bacillary load, histopathological changes in the lungs and gene expression of hspX, tgs1, tgs3 and tgs5. Diabetes was then induced by a single high dose of streptozotocin (150 mg/kg body weight). Host factors, like various cytokines and MMPs (Matrix metalloproteinases), which play an important role in the containment of mycobacterial infection were studied in vivo and in vitro. Results A murine model of latent TB was developed, which was confirmed by CFU counts (<104 in the lungs and spleen) and granuloma formation in lungs in the latent TB group. Also, the gene expression of hspX, tgs1, and tgs5 was upregulated, and after diabetes induction, blood glucose levels were >200 mg/dl. An in vitro study employing a THP-1 macrophage model of latent and active tuberculosis under normal and high glucose conditions showed that dormant bacilli were better contained in the presence of 5.5 mM glucose concentration as compared with active bacilli. However, the killing and restriction efficiency of macrophages decreased, and CFU counts increased significantly with an increase in glucose concentration. Discussion The decreased levels of MCP-1, decreased expression of mmp-9, and increased expression of mmp-1 in the latent group at high glucose concentrations could explain the failure of granuloma formation at high glucose conditions.

Abstract
Minimally invasive parathyroidectomy (MIP) is the standard of care for primary hyperparathyroidism (PHPT). Four dimensional computed tomography(4DCT) and F-18 Fluorocholine positron emission tomography/computed tomography (FCH PET/CT) localize adenomas accurately to perform MIP. We aimed to conduct a systematic review and metanalysis to evaluate the diagnostic performance of 4DCT and FCH PET/CT scan for quadrant wise localisation in PHPT patients and to do head-to-head comparison between these two modalities. DESIGN, PATIENTS AND MEASUREMENT : After searching through PubMed and EMBASE databases, 46 studies (using histology as a gold standard) of 4DCT and FCH PET/CT were included. RESULTS: Total number of patients included were 1651 and 952 for 4DCT scan (studies n = 26) and FCH PET/CT scan (studies n = 24) respectively. In per patient analysis, FCH PET/CT and 4DCT had pooled sensitivities of 92% (88-94) and 85% (73-92) respectively and in per lesion analysis, 90% (86-93) and 79% (71-84), respectively. In the subgroup with negative conventional imaging/persistent PHPT, FCH PET/CT had comparable sensitivity to 4DCT (84% [74-90] vs. 72% [46-88]). As per patient wise analysis, FCH PET/CT had better detection rates than 4DCT ([92.4 vs. 76.85], odds ratio -3.89 [1.6-9.36] p = .0024) in the subpopulation where both FCH PET/CT and 4DCT were reported. CONCLUSION: Both 4DCT and FCH PET/CT scan performed well in newly diagnosed patients, patients with persistent disease and in those with inconclusive conventional imaging results. FCH PET/CT scan had a higher pooled sensitivity than 4DCT in detecting patients with PHPT in head to head comparison.

Abstract
Parathyroid adenomas weighing more than 3.5 g are reported variously as "atypical", "large" or "giant" parathyroid adenomas. All such adenomas are rare variants accounting for no more than 1.5% of all parathyroid adenomas. Large parathyroid adenomas are often associated with more severe form of the disease, including osteitis fibrosa cystica (OFC) and share many biochemical, histological, and molecular features of both benign and malignant parathyroid neoplasms, and are considered a distinct clinical entity. However, the pathogenesis of oversized parathyroid adenomas and the often-associated skeletal phenotype remains unclear. We present 5 cases of primary hyperparathyroidism (PHPT) with OFC, an uncommon manifestation of contemporary PHPT, associated with larger parathyroid adenomas, seen in the Bone and Mineral Disorders Clinic of the Henry Ford Health in the last 30 years to illustrate the critical role of vitamin D nutrition in the pathogenesis of both the OFC and adenoma size. The estimated prevalence of OFC was very low 0.2%, 5 of the >3000 surgically confirmed cases of PHPT seen during this time. The mean ± SD values were: age: 36.8 ± 22.1 years (4 of the 5 <36years), serum calcium 11.6 ± 1.1 mg/dl, alkaline phosphatase 799 ± 487 IU/L, PTH 1440 ± 477 pg/ml, 25-hydroxyvitamin D 13.0 ± 8.9 ng/ml, 1,25-dihyroxyvitamin D 26.5 ± 13.7 pg/ml, urine calcium 562 ± 274 mg/day, and parathyroid adenoma weight 4.53 ± 2.2 g. Parathyroidectomy led to the resolution of both the biochemical indices and OFC in each patient without recurrence over >10 years of follow-up. Because OFC is a very rare in the West, but very common areas of endemic vitamin D deficiency, we also examined the relationship between vitamin D nutrition, as assessed by serum 25-hydroxyvitamin D level, and parathyroid adenoma weight as well as prevalence of OFC in two large secularly diverse cohorts of patients with PHPT (Detroit, USA and Chandigarh, India). Based on this relationship and the relative prevalence of OFC in these two large cohorts, we propose that vitamin D nutrition (and perhaps calcium nutrition) best explains both the adenoma size and prevalence of OFC.

Abstract
In the field of pharmaceutical biotechnology and formulation development, various protein and peptide-based drugs have been used for therapeutic and clinical implications. These are mainly given via parenteral routes like intravenous, subcutaneous or intramuscular delivery. Teriparatide, also known as PTH 1-34, is a U.S. Food & Drug Administartion-approved anabolic drug to treat osteoporosis is currently available in market only as subcutaneous injection. The quest for elimination of needle in case of given peptidal delivery to replace it with alternative routes like nasal, buccal, transdermal and pulmonary pathways has driven meticulous drug research. The pharmaceutical scientists are working on innovation and approaches involving new materials and methods to develop the formulations for protein and peptides by noninvasive routes. Lately, various approaches have been carried out which involve many strategies and technologies to deliver teriparatide via alternative routes. But, physicochemical instability, proteolytic degradation, low bioavailability, etc. are some obstacles to develop suitable delivery system for teriparatide. This review intends to gather the overall developments in delivery systems specific to teriparatide which meant for better convenience and avoids vulnerability of multiple subcutaneous injections. In addition, the article emphasizes on the successes to develop noninvasive technologies and devices, and new milestones for teriparatide delivery.

Abstract
Background Immunoglobulin (Ig)G4-related disease is a systemic fibroinflammatory disease characterized by dense infiltration of IgG4-positive plasma cells in the affected tissue(s) with or without elevated plasma levels of IgG4. Hypophysitis itself is a very rare disease with reported prevalence in the operative specimens are around 0.2-0.88%. IgG4-related hypophysitis (IgG4-RH) may account for a substantial percentage of cases previously regarded as idiopathic hypophysitis. Methods This study is a registry-based, retrospective, and cohort study from a tertiary care hospital in North India. The medical records and clinical data of biopsy-proven and suspected IgG4-RH patients registered were retrospectively analyzed. Treatment outcome of cases was also explored during this analysis. Results Two thousand and six sellar area space-occupying lesions have been operated-on since 2006, among them only four patients had IgG4-RH on histopathological specimen. One case was diagnosed on clinical suspicion. Mean age of the patients was 31.8 ± 6.32 years. Most frequent presenting complaint was headaches. Extracranial manifestations were present in four patients. The most common pituitary dysfunction was cortisol deficiency. 18 F-fluorodeoxyglucose positron emission tomography (18F FDG PET) was helpful in three cases for diagnosis of hypophysitis and other organ involvement. Classical histological findings with storiform fibrosis, obliterative phlebitis seen in two cases, and IgG4-positive plasma cell infiltration were positive in four cases. Surgery was the primary modality of treatment in all four cases. Only one patient received steroids as a primary therapeutic modality. Conclusion IgG4-RH is rare. High index of suspicion is required to diagnosis the case precisely. FDG PET is helpful in diagnosing hypophysitis and extrapituitary lesions.

Abstract
BACKGROUND Etiological diagnosis of delayed puberty is difficult. Despite availability of various basal and stimulation tests differentiation between constitutional delay in puberty and hypogonadotropic hypogonadism is still challenging. OBJECTIVE To elucidate the role of GnRH agonist-stimulated inhibin B (GnRH-iB) for the differential diagnosis of delayed puberty. STUDY DESIGN Participants were recruited into "exploratory cohort" (n = 39) and "validation cohort" (n = 16). "Exploratory cohort" included children with spontaneous puberty and patients with hypogonadotropic hypogonadism. "Validation cohort" constituted children who presented with delayed puberty. INTERVENTION AND OUTCOME GnRHa (Triptorelin) stimulation test along with measurement of inhibin B level at 24 h after GnRHa injection was performed in all the study participants. Cut-offs for GnRH-iB were derived from the "exploratory cohort". These cut-offs were applied to the "validation cohort". Basal LH, basal inhibin B(INH-B), GnRHa-stimulated LH at 4 h (GnRH-LH) and GnRH-iB were evaluated for the prediction of onset of puberty on prospective follow-up. RESULTS GnRH-iB at a cut-off value of 113.5 pg/ml in boys and 72.6 pg/ml in girls had 100% sensitivity and specificity for the documentation of puberty. In the "validation cohort" basal LH, basal INH-B, GnRH-LH, and GnRH-iB had a diagnostic accuracy of 68.75%, 81.25%, 68.75% and 93.75% respectively, for the prediction of onset of puberty. Basal LH, basal INH-B and GnRH-LH used alone or in combination were inferior to GnRH-iB used alone. CONCLUSION GnRHa-stimulated inhibin B (GnRH-iB) is a convenient and easily employable test for the differentiation of constitutional delay in puberty from hypogonadotropic hypogonadism.

Abstract
PURPOSE Sheehan's syndrome (SS) is characterised by chronic pituitary insufficiency following a vascular insult to the pituitary in the peripartum period. There is a lack of substantial evidence on the long-term hepatic and cardiac consequences in these patients, following hormone replacement. METHODS Patients with a diagnosis of SS were recruited for the study. Detailed clinico-biochemical and radiological evaluation were performed in all patients (n = 60). Hepatic and cardiac complications were assessed using fibroscan and echocardiography (2D speckle-tracking) respectively, in a subset of patients (n = 29) as well as age-and BMI-matched controls (n = 26). Controlled attenuation parameter (for steatosis) and liver stiffness measurement (for fibrosis) were used to define non-alcoholic fatty liver disease (NAFLD). Diastolic cardiac function was evaluated using standard criteria and systolic function by ejection fraction and global longitudinal strain (GLS). RESULTS The mean age of the cohort was 42.7 ± 11.6 years. Multiple (≥ 2) hormone deficiencies were present in 68.8% of patients, with hypothyroidism (91.4%), hypocortisolism (88.3%), and growth hormone (GH) deficiency (85.7%) being the most common. At a mean follow-up of 9.8 ± 6.8 years, NAFLD was present in 63% of patients, with 51% having severe steatosis, which was predicted by the presence of GH deficiency and higher body mass index. Though the ejection fraction was similar, increased left ventricular GLS (18.8 vs. 7.7%) was present in a significantly higher number of patients versus controls. CONCLUSION NAFLD, especially severe hepatic steatosis, is highly prevalent in SS. Subclinical cardiac systolic dysfunction (impaired GLS) is also more common, but of mild intensity.

Abstract
Background Lymphocytic thyroiditis (LT) is frequently seen in the tumor microenvironment (TME) of papillary thyroid carcinomas (PTCs). However, the characteristic of these tumor-infiltrating lymphocytes (TILs) is not well understood. Objective We aim to define the TME of PTC cases by characterizing the TILs. Design This is a cross-sectional observational study. Patients We enrolled 29 PTC (23 having concurrent LT), 14 LT, and 13 hyperplastic nodules with LT (HN) patients from January 2016 to December 2020. Measurements Immunohistochemical (IHC) expression of CD8, FoxP3, PD-1, and PD-L1 was studied in PTC with LT and compared with HN. PD-1 and PD-L1 expression was correlated at the mRNA level by quantitative real-time PCR. Immunophenotyping of TILs was done in FNAC samples of PTC and LT by flow cytometry. Results IHC revealed the presence of CD8+ cytotoxic T lymphocytes (CTLs) and FoxP3+ T regulatory cells (Tregs) in 83% and 52% of PTC with LT cases, respectively. Flow cytometric analysis of the PTC samples revealed a significant abundance of CTL compared with Treg and a higher CTL with lower Treg counts compared with LT. On IHC, PD-1 positivity was noted in 56.5% of PTC with LT cases, while intermediate PD-L1 positivity was found in 70% of the cases. There was a significant upregulation of PD-1 mRNA in PTC with LT. A significant correlation was noted with PD-L1 expression with lymph node metastasis and presence of Treg cells. Conclusions Increased expression of PD-1 and PD-L1 in the TME of PTC may provide a potential molecular mechanism for tumor survival despite the predominance of CTLs, possibly through their inactivation or exhaustion.

Abstract
BACKGROUND Varied reports suggest a contentious relationship of bladder malignancy with pioglitazone in patients with type 2 diabetes. AIM To study an association (prevalence and predictors) of bladder malignancy with pioglitazone therapy in Asian-Indian type 2 diabetes patients. METHOD In this observational multicenter study, type 2 diabetic patients attending out-patient diabetes-clinic were evaluated. A detailed history of anti-diabetic medication, dose, duration, pioglitazone usage, time since initiation of pioglitazone, physical examination, biochemical tests and details pertaining to prevalent neuropathy, retinopathy and nephropathy were recorded. Details of bladder cancer or any malignancy (if present), time since diagnosis, risk factors for bladder cancer and histopathology records were noted. The study cohort was divided into two groups-pioglitazone ever users (Group A) and never users (Group B). RESULTS A total of 8000 patients were screened out of which 1560 were excluded. Among 6440 included patients, 1056 (16.3%) patients were in group A and 5384 (83.6%) group B. Patients on pioglitazone were older (59.1 vs 57.7 years, p < 0.001), had longer duration of diabetes (12.7 vs 10.6 years, p < 0.001) with poor glycemic control (HbA1c 8.5 vs 8.3%, p < 0.01). A total of 74 patients had prevalent bladder cancer [16 (1.5%) in Group A and 58 in Group B (1.0%)]. Prevalent bladder cancer was not significantly greater in ever-users (odds ratio OR = 1.29, 95% confidence interval CI, 0.83-2.00) compared to never-users (odds ratio OR = 0.94, 95% confidence interval CI, 0.834-1.061) of pioglitazone (p = 0.207). However, history of hematuria in pioglitazone-users; while older age (>58 year), history of smoking and hematuria in the whole cohort were significant associated with bladder cancer. In the entire study cohort, 254 patients; 3.5% of males (128 out of 3575) and 4.6% of females (126 out of 2713) developed any malignancy. Age was significantly associated with prevalent malignancy in people with diabetes (odds ratio OR 1.036, 95% confidence interval CI: 1.022-1.051, p = 0.00) on multivariate forward regression. CONCLUSION Pioglitazone use in Asian-Indians is not associated with an increased bladder cancer risk. However, pioglitazone should be restricted in individuals with history of hematuria. Age more than 58 years is a significant risk factor for development of any malignancy, particularly bladder cancer.

Abstract
BACKGROUND AND OBJECTIVES Pre-diabetes has been identified as an intermediate diagnosis and a sign of a relatively high chance of developing diabetes in the future. Diabetes has become one of the most frequent chronic disorders in children and adolescents around the world; therefore, predicting the onset of pre-diabetes allows a person at risk to make efforts to avoid or restrict disease progression. This research aims to create and implement a cross-validated machine learning model that can predict pre-diabetes using non-invasive methods. METHODS We have analysed the national representative dataset of children and adolescents (5-19 years) to develop a machine learning model for non-invasive pre-diabetes screening. Based on HbA1c levels the data (n = 26,567) was segregated into normal (n = 23,777) and pre-diabetes (n = 2790). We have considered eight features, six hyper-tuned machine learning models and different metrics for model evaluation. The final model was selected based on the area under the receiver operator curve (AUC), Cohen's kappa and cross-validation score. The selected model was integrated into the screening tool for automated pre-diabetes prediction. RESULTS The XG boost classifier was the best model, including all eight features. The 10-fold cross-validation score was highest for the XG boost model (90.13%) and least for the support vector machine (61.17%). The AUC was highest for RF (0.970), followed by GB (0.968), XGB (0.959), ETC (0.918), DT (0.908), and SVM (0.574) models. The XGB model was used to develop the screening tool. CONCLUSION We have developed and deployed a machine learning model for automated real-time pre-diabetes screening. The screening tool can be used over computers and can be transformed into software for easy usage. The detection of pre-diabetes in the pediatric age may help avoid its enhancement. Machine learning can also show great competence in determining important features in pre-diabetes.

Abstract
Patients with primary hyperparathyroidism (PHPT) have higher body weight than their eucalcemic peers (1). However, most of the data is based on Caucasian PHPT patients who predominantly have an asymptomatic presentation. Similar data from Asian-Indian patients with PHPT who primarily have symptomatic disease are unavailable. In this regard, we planned to conduct a retrospective observational study to look into the dynamics of body weight in Asian-Indian PHPT patients. The medical records of PHPT patients (≥18 years) managed at Postgraduate Institute of Medical Education and Research, India, from July 2005 to December 2020 were retrieved from the Indian PHPT Registry (www.indianphptregistry.com). Patients who had achieved biochemical cure after parathyroidectomy with documentation of preoperative and at least one postoperative body weight 6 months to 2 years after surgery were included. Patients with recurrent/persistent/syndromic PHPT, chronic kidney disease (eGFR <90 ml/min/1.73 m2), parathyroid carcinoma, and incomplete records were excluded. After exclusion, a total of 243 patients were included in analysis (mean age=43.9±13.7 years, women 79.8%). The majority of the patients had symptomatic disease, while only 43 patients (18%) were asymptomatic at presentation. The predominant presenting manifestations were renal stone disease (52%), bone pain (40%), gastrointestinal symptoms (anorexia, nausea, vomiting, constipation) (30%), generalized weakness (26%), weight loss (23%), fragility fractures (16%), cholelithiasis (13%) and acute pancreatitis (7%). The mean preoperative body weight was 59.9±13.4 kg. Patients with PHPT had lower body weight compared to an equal number (n=243) of age- and sex-matched community-dwelling healthy controls (p<0.001 for both men and women). At median follow-up of 1 year, the mean postoperative body weight was 64.7±12.6 kg. The median (interquartile range) percent change is body weight was +6.7% (+2.1, +14.0). Increase in body weight was noted in 198 patients (81.5%). Univariate analysis showed that patients with postoperative weight gain were younger (p=0.029), had lower body weight (p<0.001), were more likely to be symptomatic (p=0.002), and more likely to have weight loss (p=0.041) and gastrointestinal symptoms (p=0.016) at presentation compared with patients with no weight gain. Similarly, patients with weight gain had significantly higher preoperative serum calcium (p=0.044), alkaline phosphatase (ALP) (p=0.001), and parathyroid hormone levels (p=0.001), indicating biochemically severe disease On binomial logistic regression analysis, preoperative body weight (β= -0.045, p=0.04), symptomatic presentation (β=0.217, p=0.02), and ALP (β=0.003, p=0.04) emerged as significant predictors of postoperative weight gain. In conclusion, Asian-Indians with symptomatic PHPT have lower body weight than healthy controls, likely because of significant gastrointestinal manifestations that compromise food intake. It is plausible that following reinstatement of eucalcemia, appetite improves, resulting in increased food intake and subsequent weight gain. Nevertheless, long-term follow-up studies evaluating the metabolic consequences of this postoperative weight gain are needed.Reference: (1) Bolland et al., J Clin Endocrinol Metab. 2005;90(3): 1525–30.

Abstract
Primary hyperparathyroidism (PHPT) is third most common endocrine disorder characterized by hypercalcemia with elevated or nonsuppressed parathyroid hormone levels by parathyroid tumors. Familial PHPT, as part of multiple endocrine type-1, occurs due to the germline mutation in the MEN1 gene. The involvement and the role of germline MEN1 variations in sporadic PHPT of Indian PHPT patients are unknown. Precise classifications of different types of MEN1 variations are fundamental for determining clinical relevance and diagnostic role. This prospective cohort study was performed on 82 patients with PHPT (with no clinical or history of MEN1) who underwent screening for MEN1 variations through Sanger sequencing. Multilevel computational analysis was performed to determine the structure-function relationship of synonymous, nonsynonymous, and variants of uncertain significance (VUS). Of the 82 PHPT patients, 42 (51%) had 26 germline MEN1 variants, including eight nonsynonymous, seven synonymous, nine VUS, one splice site, and one regulatory variation. Five most common germline variations (c.1838A>G, c.1817C>T, c.1525C>A, c.-35A>T, and c.250T>C) were observed in this study. c.-35A>T (5' untranslated region [UTR]) was associated with recurrence of PHPT (odds ratio [OR] = 5.4; p = 0.04) and subsequent detection of other endocrine tumors (OR = 13.6, p = 0.035). c.1525C>A was associated with multi glandular parathyroid tumor (OR = 13.6, p = 0.035). Align-Grantham variation and Grantham deviation (Align-GVGD), functional analysis through hidden Markov MODEL (FATHMM), and MutationTaster analysis reported the disease-specific potential of VUS and synonymous variations. Significant linkage disequilibrium was observed in c.1785G>A and c.1817C>T (r2 = 0.3859, p = 0.0001), c.1475C>G and c.1525C>A (r2 = 0.385, p = 0.0004), and c.1569T>C and c.1838A>G (r2 = 0.488, p = 0.0001). The detection of MEN1 variations, especially those with disease-specific potential, can prompt early screening for other MEN1-related tumors and disease recurrence. © 2022 American Society for Bone and Mineral Research (ASBMR).
