We compared the efficacy of spironolactone (50 mg/d) with metformin (1000 mg/d) after random allocation in 82 adolescent and young women with polycystic ovary syndrome (PCOS) on body mass index (BMI), waist-to-hip ratio, blood pressure, menstrual cyclicity, hirsutism, hormonal levels, glycemia, and insulin sensitivity at baseline and at the 3rd and 6th months of treatment. Sixty-nine women who completed the follow-up had a mean age of 22.6 +/- 5.0 yr and mean BMI of 26.8 +/- 4.0 kg/m2. The number of menstrual cycles in the spironolactone and metformin groups increased from 6.6 +/- 2.1 and 5.7 +/- 2.3 at baseline to 9.0 +/- 1.9 and 7.4 +/- 2.6 at 3rd month and to 10.2 +/- 1.9 and 9.1 +/- 2.0/ year at the 6th month (P = 0.0037), respectively. The hirsutism score decreased from 12.9 +/- 3.2 and 12.5 +/- 4.9 at baseline to 10.1 +/- 3.1 and 11.4 +/- 4.1 at the 3rd month and to 8.7 +/- 1.9 and 10.0 +/- 3.3 at the 6th month, respectively. Both groups showed improvement in glucose tolerance and insulin sensitivity, although the metformin effect was significant in the latter. Serum LH/FSH and testosterone decreased in both groups. BMI, waist-to-hip ratio, and blood pressure did not change with either drug. We conclude that both drugs are effective in the management of PCOS. Spironolactone appears better than metformin in the treatment of hirsutism, menstrual cycle frequency, and hormonal derangements and is associated with fewer adverse events.

Frailty has emerged as a major health issue among older patients. A consensus on definition and diagnosis is yet to be achieved. Various biochemical abnormalities have been reported in frailty. Activation of sirtuins, a conserved family of NAD-dependent proteins, is one of the many mimics of calorie restriction which improves lifespan and health in experimental animals. In this cross-sectional study, we assessed the circulating sirtuin levels in 119 (59.5%) nonfrail and 81 (40.5%) frail individuals, diagnosed by Fried's criteria. Serum SIRT1, SIRT2, and SIRT3 were estimated by surface plasmon resonance (SPR) and Western blot. Serum sirtuins level in mean+SD; SIRT1 (nonfrail –4.67 ± 0.48 ng/μL; frail – 3.72 ± 0.48 ng/μL; P < 0.0001), SIRT2 (nonfrail – 15.18 ± 2.94 ng/μL; frail – 14.19 ± 2.66 ng/μL; P = 0.016), and SIRT3 (nonfrail-7.72 ± 1.84 ng/μL; frail – 6.12 ± 0.97 ng/μL; P < 0.0001) levels were significantly lower among frail patients compared with the nonfrail. In multivariable regression analysis, lower sirtuins level were significantly associated with frailty after adjusting age, gender, diabetes mellitus, hypertension, cognitive status (Mini Mental State Examination scores) and number of comorbidities. For detecting the optimum diagnostic cutoff value a ROC analysis was carried out. The area under curve for SIRT1 was 0.9037 (cutoff – 4.29 ng/μL; sensitivity – 81.48%; specificity – 79.83%) and SIRT3 was 0.7988 (cutoff – 6.61 ng/μL; sensitivity – 70.37%; specificity – 70.59%). This study shows that lower circulating SIRT1 and SIRT3 levels can be distinctive marker of frailty.

One hundred and ten adult patients hospitalized with dengue haemorrhagic fever (DHF) during the recent outbreak in North India were prospectively studied. Of these, 48 (43.6%) were grade I, 40 (36.4%) grade II, 10 (9.1%) grade III and 12 (10.9%) grade IV DHF. Dengue shock syndrome (DSS) was seen in 22 (20%) patients. Fever, headache, myalgias and arthralgias were the common symptoms seen in 100%, 80.9%, 76.2% and 52.3% patients, respectively. Spontaneous bleeding was seen in 62 patients (56.4%) with mucocutaneous bleeding being the most common (46 patients). Gastrointestinal bleeding was seen in 38 (34.5%) patients. In as many as 40 patients, the haemorrhagic manifestations occurred after the fever had come down. Fifty-five patients (50%) required platelet transfusions. Twelve patients died, giving a mortality rate of 10.9% in the present study. Prompt recognition and supportive treatment can be lifesaving.

The elevated level of cerebrospinal fluid (CSF) Tau and phosphorylated Tau181 (p-Tau181) proteins are well established hallmarks of Alzheimer’s disease (AD). Elevated level of p-Tau181 can differentiate AD from other neurodegenerative disease. However, the expression level of these proteins in serum of AD patient is not well set up. This study sought to evaluate the level of Tau and p-Tau181 in serum of AD, and mild cognitive impairment (MCI) patients for an alternative approach to establish protein-based markers by convenient way. Blood samples were collected from 39 AD patients, 37 MCI patients and 37 elderly individuals as controls. The levels of Tau and p-Tau181 in the serum of the different groups were measured by label free real time Surface Plasmon Resonance technology by using specific antibodies, and were further confirmed by the conventional western blot method. An appropriate statistical analysis, including Receiver Operating Characteristic (ROC), was performed. The concentrations of serum Tau and p-Tau181 were significantly higher (p<0.00001) in AD (Tau; 47.49±9.00ng/μL, p-Tau181; 0.161±0.04 ng/μL) compared to MCI (Tau; 39.26±7.78 ng/μL, p-Tau181; 0.135±0.02 ng/μL) and were further higher compared to elderly controls (Tau; 34.92±6.58 ng/μL, p-Tau181; 0.122±0.01 ng/ μL). A significant (p<0.0001) downhill correlation was found between Tau as well as p-Tau181 levels with HMSE and MoCA score. This study for the first time reports the concentration of Tau and p-Tau181 in serum of AD and MCI patients. The cutoff values of Tau and p-Tau181 of AD and MCI patients with sensitivity and specificity reveal that serum level of these proteins can be used as a predictive marker for AD and MCI.

The study findings demonstrate that currently ocular trauma, infectious keratitis, post-surgical bullous keratopathy, and corneal degenerations are responsible for the major burden of corneal blindness and morbidity in the Indian population. The prevalence of corneal morbidity due to vitamin A deficiency and trachoma was low in this rural population.

Women with PCOS had an exaggerated insulin response to glucose. Thirty-eight percent of PCOS women had some form of abnormal glucose tolerance. Greater insulin response was seen with impairment of glucose tolerance. Obesity had no effect on fasting insulin or insulin response to oral glucose in PCOS women with NGT.
