The responsibilities of health care professionals, too, extend far beyond the management of the disease. Health care providers focus not only on patients and drugs, but also work toward ensuring health in the community at large, using non-pharmacological means wherever appropriate. The aim of these interventions is not just to cure, but to prevent as well. One strategy to ensure good health is to maintain optimal hygiene.

There is a paucity of nationally representative data on the dynamics of these risk factors, which have not been assessed among healthy reproductive-age Indian women. Objective This cross-sectional polycystic ovary syndrome (PCOS) task force study aimed to assess the anthropometric and sociodemographic characteristics of healthy reproductive-age Indian women and explore the association of these characteristics with various noncommunicable diseases. Methods We conducted a nationwide cross-sectional survey from 2018 to 2022 as part of the Indian Council of Medical Research–PCOS National Task Force study, with the primary aim of estimating the national prevalence of PCOS and regional phenotypic variations among women with PCOS. A multistage random sampling technique was adopted, and 7107 healthy women (aged 18-40 years) from 6 representative geographical zones of India were included in the study. The anthropometric indices and sociodemographic characteristics of these women were analyzed. Statistical analysis was performed to assess the association between exposure and outcome variables. Results Of the 7107 study participants, 3585 (50.44%) were from rural areas and 3522 (49.56%) were from urban areas. The prevalence of obesity increased from 8.1% using World Health Organization criteria to 40% using the revised consensus guidelines for Asian Indian populations. Women from urban areas showed higher proportions of overweight (524/1908, 27.46%), obesity (775/1908, 40.62%), and prehypertension (1008/1908, 52.83%) categories. A rising trend of obesity was observed with an increase in age. Women aged 18 to 23 years were healthy (314/724, 43.4%) and overweight (140/724, 19.3%) compared with women aged 36 to 40 years with obesity (448/911, 49.2%) and overweight (216/911, 23.7%). The proportion of obesity was high among South Indian women, with 49.53% (531/1072) and 66.14% (709/1072), using both World Health Organization criteria and the revised Indian guidelines for BMI, respectively. BMI with waist circumference and waist-to-height ratio had a statistically significant linear relationship (r=0.417; P<.001 and r=0.422; P<.001, respectively). However, the magnitude, or strength, of the association was relatively weak (0.3<|r|<0.5). Statistical analysis showed that the strongest predictors of being overweight or obese were older age, level of education, wealth quintile, and area of residence. Conclusions Anthropometric and sociodemographic characteristics are useful predictors of overweight- and obesity-related syndromes, including prehypertension, among healthy Indian women. Increased attention to the health of Indian women from public health experts and policy makers is warranted. The findings of this study can be leveraged to offer valuable insights, informing health decision-making and targeted interventions that mitigate risk factors of overweight, obesity, and hypertension.

Hence, this study attempted to understand usage, efficacy and safety of saxagliptin as first add-on after metformin in Indians with T2DM. Methodology: It was a multicenter, prospective, non-interventional and observational study planned to enrol T2DM patients who were inadequately controlled with metformin alone and had been recently (i.e., within past 15 days) prescribed saxagliptin as an add-on to metformin. Type 1 diabetes mellitus, use of glucose lowering drugs apart from metformin or saxagliptin, pregnancy, lactation, and medical condition, which could interfere with safe completion of the study were excluded. Results: A total of 1109 participants (658 men and 451 women) with mean ± SD age of 51.17 ± 11.85 years were enrolled from 50 centres throughout India. Significant reduction was observed in mean ± SD change of HbA1c as − 0.86% ± 1.76 from baseline to after 3 months of therapy (P < 0.0001). The quality of life assessed by World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire was reported to be “good” or “neither good nor bad” by majority of the participants at baseline and after 3 months of treatment. A total of 15 adverse events (AEs) were reported in the study, however, no serious adverse event (SAE) occurred during the study. All AEs were of mild intensity and did not require any intervention. Conclusion: Overall, saxagliptin in combination with metformin was generally well-tolerated in Indian T2DM patients and new or unexpected safety events were not identified. This study is also registered on Clinicaltrials.gov (NCT02588859).

Of all the neurological complications of diabetes, peripheral neuropathy is by far the commonest and has been extensively studied. The involvement of central nervous system can be in several forms. The underlying damage may be due to involvement of the large and small cerebral blood vessels as also due to metabolic derangement caused by prolonged hypoglycemia, anoxia or ketoacidosis. The neurological emergencies that occur in diabetes can be: 1) atherothrombotic and lacunar strokes; 2) convulsive disorder in the setting of both hypo and hyperglycemia; 3) coma; 4) cranial neuropathies; and 5) acute proximal muscle weakness. In patients with diabetes, atherothrombotic stroke is associated with poor outcome. Hyperglycemia at the time of stroke is an important risk factor for an adverse outcome than chronic stable diabetic state. Proper management of diabetes in these acute situations is crucial for a better outcome of the underlying disease process.

Useful for all types of patients Insulin degludec is next generation insulin with a unique mode of protraction of forming soluble multi-hexamers and slow continuous absorption giving it a flat profile compared to the existing basal insulin. In patients with type 1 diabetes or with type 2 diabetes, at steady-state, the mean terminal half-life of insulin degludec was 25 hours, i.e., approximately twice as long as for insulin glargine (half-life of 12.1 hours). In once-daily dosing regimen it reaches steady state after approximately 3 days. The duration of action of insulin degludec was estimated to be beyond 42 hours in euglycaemic clamp studies and this gives the unique opportunity of flexible time dosing which is not an available option with the existing basal insulin. The glucose-lowering effect is evenly distributed across a 24-hour dosing interval with insulin degludec having 4 times lower variability than insulin glargine. This is an important attribute given the narrow therapeutic window of insulin and the goal of achieving night time and inter-prandial glycaemic control without increasing the risk for hypoglycaemia, a goal that is challenging given the variability of absorption and lower PK half-lives of current basal insulin products. The combination of the ultra-long, flat and stable profile with an improved hour-to-hour and day-to-day variability could present an improved risk-benefit trade-off with the lower risk of hypoglycaemia, allowing for targeting improved levels of glycaemic control.
