ItemNo Preview AvailableBone Mineral Density and Body Composition in Males with Motor Neuron Disease: A Study from Teaching Hospital in Southern Part of India(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2021)BACKGROUND: Osteoporosis and sarcopenia are important aspects of motor neuron disease (MND). Individuals with amyotrophic lateral sclerosis (MND-ALS) have an increased risk of falls and fractures. Currently, the standard of care does not involve a routine assessment of bone mineral density (BMD) and body composition in these patients. We aimed to assess BMD, bone mineral parameters and body composition in men with MND and compared them with healthy controls. METHODS: Consecutive males between 50 and 80 years of age diagnosed as MND-ALS by revised El Escorial criteria and able to walk unassisted attending Neurology outpatient clinic were recruited into the study. Age, gender and body mass index (BMI) matched healthy controls were recruited from the local community. BMD and body composition were assessed by dual-energy x-ray absorptiometry (DXA). Bone mineral parameters and bone turnover markers (BTMs) were also assessed in them. RESULTS: A total of 30 subjects with MND-ALS and 33 controls were recruited. The mean age (years) was 59.2 in cases and 61.2 in controls. The mean BMD (g/cm2) between the two groups was similar; however, BTMs were significantly higher in the MND group (P < 0.05). Subjects with MND-ALS had significantly lower mean appendicular lean mass (ALM) (19.9 versus 22.4 kg; P = 0.007) and ALM corrected for BMI than the healthy control group (0.858 versus 0.934 kg/kg/m2; P = 0.034). Sarcopenic obesity (Percentage fat mass >27% + ALM/BMI <0.786 kg/kg/m2) was more prevalent in MND-ALS compared to controls (44.5% versus 16.7%; P = 0.03). CONCLUSION: Although BMD was not significantly different between subjects with MND-ALS and healthy controls, BTMs were significantly higher in the MND group indicating a high bone turnover state. Sarcopenia and sarcopenic obesity were also more in MND-ALS group than controls. Routine assessment for bone health parameters and body composition indices may be included in management of the patients with MND.

ItemKnowledge gap regarding osteoporosis among medical professionals in Southern India.(Wiley, 2020-02)RATIONALE, AIMS, AND OBJECTIVES: Osteoporosis is a common health problem in India, which leads to significant morbidity and mortality in elderly individuals. Lack of knowledge and awareness among medical professionals is one of the important barriers in management of these patients. Therefore, this study was conducted to assess knowledge pertaining to diagnosis and treatment of osteoporosis among a group of Indian medical practitioners. METHODS: The study participants included 222 allopathic medical professionals, either graduate or postgraduate working in primary or secondary health care levels. They were assessed using a previously validated Fogelman's multiple choice questionnaire. Out of a total of 18 questions, four questions pertained to knowledge of diagnosis, three questions to treatment decisions, one question to assess knowledge regarding recommended dosage of vitamin D and calcium supplementation, five questions concerned medication use, and the rest to assess attitude and practices. The correct answers were converted into scores and expressed as percentages with a maximum of 100. RESULTS: The mean total score among them was 22.5%, which was quite low. Almost all of them had a score of less than 50%. Medical practitioners performed better in diagnosis-related questions, (19.4% answered all options correctly) than in medication knowledge (no correct response regarding side effects and 2% regarding contraindications). In treatment-related decisions, 37.4% answered correctly for duration of treatment, and 59% answered correctly for treatment goal. Only 1.4% of them were able to answer correctly regarding recommended calcium and vitamin D intake. Professional literature, conferences, and Continuing Medical Education (CME's) were regarded as the main sources of information on the subject by 40% of practitioners. CONCLUSION: This study showed suboptimal knowledge among a group of medical professionals regarding various aspects of diagnosis and management of osteoporosis, and it stipulates the need for escalating the efforts to improve their knowledge regarding various aspects of osteoporosis.

ItemNo Preview AvailableSevere Idiopathic Osteoporosis in a Premenopausal Woman: A Case for Dual Therapy.(Medknow, 2020)Currently available agents improve bone mineral density (BMD) values on their own in monotherapy but may not completely restore microarchitecture and the patient may continue to sustain fragility fractures. Current monotherapies can only address either increased bone resorption or decreased bone formation. In this setting, combination therapy with antiresorptive and anabolic agents appears to be a promising option. A 49-year-old premenopausal woman presented with severe low backache associated with significant height loss. Evaluation elsewhere revealed severe osteoporosis, which prompted treatment with three doses of parenteral zoledronate 4 mg annually, followed by oral alendronate 70 mg once weekly for 7 years. However, her symptoms persisted despite treatment, and investigations done at our center confirmed severe osteoporosis, with multiple vertebral compression fractures. She was initiated on teriparatide therapy but despite 1 year of treatment, there was persistent height loss. In addition, there was a marked elevation of bone resorption, which prompted us to add denosumab which was administered subcutaneously every 6 months. On follow-up, there was marked relief from pain, no further decrease in height, and progressive improvement in BMD, and bone turnover markers were noted. A dual therapy with anabolic agent teriparatide and antiresorptive agent denosumab for osteoporosis may be a viable option in individuals with severe osteoporosis who do not respond well to a single agent.

ItemNo Preview AvailableManagement of late-onset hypogonadism: person-centred thresholds, targets, techniques and tools(ROYAL COLL PHYSICIANS EDINBURGH, 2021-03)Late-onset hypogonadism (LOH) is a complex and highly debatable syndrome in ageing men, which is characterised by reduced testosterone levels associated with classical symptoms of androgen deficiency. This article discusses the complex issues surrounding its management related to patient-centric thresholds and therapeutic targets. It specifically highlights the need to consider symptoms as the starting point, the key milestones in the management and the target of treatment, while ensuring safety at all times. The diagnosis of LOH requires a high index of suspicion and early identification of symptoms followed by appropriate investigations. The threshold for initiation of treatment has to be person centric and requires individualised decisions. The dose, preparation, route and follow up after testosterone initiation also may vary among different people. A person-centred approach is key to the successful management of this complex, nebulous yet debilitating disease.

ItemMyelofibrosis and Pancytopenia Associated With Primary Hyperparathyroidism.(Elsevier BV, 2021)OBJECTIVE: Primary hyperparathyroidism (PHPT) has varied clinical presentations. Hematologic abnormalities secondary to PHPT have been described before. However, pancytopenia as the initial presentation has rarely been reported. We report a patient with PHPT who presented for evaluation of pancytopenia. METHODS: Histopathology of the bone marrow at presentation is described. Bone biochemistry results and the hematologic profile before and after curative parathyroidectomy are presented. RESULTS: A 48-year-old woman presented with pancytopenia (hemoglobin, 6.3 g/dL; total leucocyte count, 3000 cells/mm3; and platelet count, 60 000 cells/mm3), and her bone marrow study showed marrow fibrosis. Biochemical evaluation revealed hypercalcemia (15.5 mg/dL), hypophosphatemia (2.2 mg/dL), and elevated total alkaline phosphatase (4132 U/L). Bone mineral density assessment by dual-energy X-ray absorptiometry scan revealed osteoporosis at all 3 sites, which was more severe in the distal one third of the forearm. Further investigations confirmed the diagnosis of PHPT (serum parathyroid hormone, 2082 pg/mL). Following curative parathyroidectomy, in addition to normalization of calcium, there was restoration of all 3 hematologic cell lines at 3 months. CONCLUSION: Pancytopenia may be a rare manifestation of PHPT. Thus, it may be prudent to evaluate the calcium profile in patients with chronic refractory anemia and pancytopenia.

ItemConsensus on Medical Nutrition Therapy for Diabesity (CoMeND) in Adults: A South Asian Perspective(DOVE MEDICAL PRESS LTD, 2021)Diabetes and obesity are both increasing at a fast pace and giving rise to a new epidemic called diabesity. Lifestyle interventions including diet play a major role in the treatment of diabetes, obesity and diabesity. There are many guidelines on dietary management of diabetes or obesity globally and also from South Asia. However, there are no global or South Asian guidelines on the non-pharmacological management of diabesity. South Asia differs from the rest of the world as South Asians have different phenotype, cooking practices, food resources and exposure, medical nutrition therapy (MNT) practices, and availability of trained specialists. Therefore, South Asia needs its own guidelines for non-pharmacological management of diabesity in adults. The aim of the Consensus on Medical Nutrition Therapy for Diabesity (CoMeND) in Adults: A South Asian Perspective is to recommend therapeutic and preventive MNT in the South-Asians with diabesity.

ItemMedical nutrition therapy of pediatric type 1 diabetes mellitus in India: Unique aspects and challenges(WILEY-HINDAWI, 2021-02)Medical nutrition therapy (MNT) is a vital aspect of management of type 1 diabetes mellitus (T1DM) and should be tailored to ethnic and family traditions and the socioeconomic and educational status of the patient. In this article, we discuss the unique aspects of MNT in children and adolescents with T1DM in the Indian setting, with focus on the challenges faced by patients, dieticians and physicians and how these can be overcome. The authors reviewed the available literature on MNT in T1DM from India and prepared the document based on their vast collective clinical experience in treating patients with T1DM from different regions in India. Indian diets are predominantly carbohydrate-based with high glycemic index (GI) and low protein content. Various methods are available to increase the protein and fiber content and reduce the GI of food in order to limit glycemic excursions. Insulin regimens need to be tailored to the child's school timings, meal schedule, and the availability of a responsible adult to supervise/administer insulin. All patients, irrespective of economic and education background, should be taught the broad principles of healthy eating, balanced diet and carbohydrate counting. There are various barriers to dietary compliance, including joint family system, changing lifestyles, and other factors which need to be addressed. There is a need to customize dietary management according to patient characteristics and needs and develop standardized patient educational material on principles of healthy eating in various regional languages.

ItemNo Preview AvailableThe Prevalence and Predictors of Non-alcoholic Fatty Liver Disease in Morbidly Obese Women - A Cross-sectional Study from Southern India.(Touch Medical Media, Ltd., 2020-10)BACKGROUND: The prevalence of obesity is increasing rapidly in India and so are its associated comorbidities. Non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of metabolic syndrome, is commonly associated with obesity. However, limited data are available on its prevalence and clinical indicators among morbidly obese Indian women. The aim of our study was to find the prevalence of NAFLD in morbidly obese Indian women and study the clinically measurable obesity indicators that would best predict NAFLD. METHODS: This was a cross-sectional study, conducted in the Department of Endocrinology, Diabetes and Metabolism, Christian Medical College, Vellore. Women were enrolled who were diagnosed to have NAFLD on sonography. Anthropometric variables, such as body mass index, waist circumference, hip circumference, waist-hip ratio and waist-height ratio were measured and compared between the two groups. SPSS Statistics 21.0 software was used for analysing the data. RESULTS: One hundred and six consecutive, morbidly obese women were recruited in this study. Nearly three-quarters (73.6%) of the 106 morbidly obese participants were found to have NAFLD. We found waist circumference, body mass index and waist-height ratio to be most useful in distinguishing between patients with and without NAFLD, and found waist-height ratio was the best screening tool for diagnosing NAFLD. CONCLUSION: NAFLD is present in a large proportion of morbidly obese women. Waist-height ratio could be used a surrogate screening tool to detect NAFLD in resource-constrained settings.
