End-stage renal disease (ESRD) has increased in India due to the growing load of non-communicable diseases. The most prevalent psychological issue among these patients has been identified as depression, which may have an impact on treatment success. Around 20% to 90% of hemodialysis patients experience depression. The current study aimed to determine the prevalence of depression among patients undergoing hemodialysis as well as the relationship between this condition and the sociodemographic and clinical parameters of the patients. Basic demographic information and particulars of chronic morbidity, duration, and the number of cycles of hemodialysis per week were noted. The Beck Depression Inventory (BDI) score was administered to screen for depression. A total of 92 participants were enrolled in the study; 69 (75%) were males. The mean age of participants was 52 years. Hypertension (100%) was the most common co-morbidity followed by diabetes mellitus (38%). The mean duration of chronic kidney disease was 3.9 years. The majority (68.5%) had hemodialysis twice per week. Forty-one percent (41%) screened positive for borderline clinical depression or more. The mean BDI score was 17.07. The number of hemodialyses per week had a significant relation with depression with an odds ratio of 4.16 and 95% CI of 1.4-12.38. Depression is prevalent among patients with chronic kidney disease who are on dialysis. The management of this preventable illness demands a repertoire of measures such as launching a program for the detection and treatment of depression combining psychiatric professionals and social volunteer organizations.

BACKGROUND Globally, diabetic nephropathy (DN) is the primary cause of chronic kidney disease. Currently, renal function is monitored indirectly using measures of serum creatinine, estimated glomerular filtration rate (eGFR), and proteinuria. Novel urinary biomarkers utilized in the early stages of DN have been described; these indicators can be used in the early identification of the disease, which is important for initiating treatment to halt or impediment the advance of diabetic nephropathy. AIM To estimate neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and periostin (POSTN) levels as novel urinary biomarkers in DN. METHODS In this hospital based cross-sectional study, a total of 160 patients of both genders aged 18 years or more; 40 healthy participants and 120 patients with diabetes mellitus (DM) were included. Patients with DM were divided into normoalbuminuria (n = 40), microalbuminuria (n = 40), and macroalbuminuria (n = 40) groups as per urine albumin creatinine ratio (uACR). Blood urea, serum creatinine, uACR were measured. Urine NGAL, KIM-1, and POSTN were measured by enzyme linked immunosorbent assay. The eGFR was calculated and compared with urinary markers. RESULTS NGAL, KIM-1, and POSTN levels increased significantly in normo, micro, and macroalbuminuria with the highest in the macroalbuminuria group. Albumin creatinine ratio (ACR) showed a positive correlation with NGAL, KIM-1, and POSTN levels. The eGFR showed a weak negative correlation with ACR, NGAL, KIM-1, and POSTN. NGAL was significantly lower in stage 1 compared to stage 2, 3, and 4 kidney disease. KIM-1 was significantly decreased in stage 1 compared to stage 4 kidney disease. POSTN was significantly decreased in stage 1 compared to stage 3 and 4 kidney disease. The receiver operator curve analysis of ACR, NGAL, KIM-1, and POSTN showed good sensitivity of 80%, 75.8%, 63.3%, and 80 % respectively with a cut-off of 12.5 mg/g, 4.5 μg/L, 1.5 ng/mL, and 37.5 ng/mL. CONCLUSION Urinary NGAL and POSTN are independent markers of DN.

A BSTRACT: Background: Cerebrovascular disease is the second most common cause of death in people more than 60 years of age. Predicting the outcome of the stroke is a great challenge for physicians. Various risk factors such as age, sex, co-morbidities, smoking and alcohol habits, type of stroke, National Institute of Health Stroke Scale (NIHSS) score, modified Rankin Scale (mRS), and others play the role in the outcome of stoke. Aim: To assess the degree of impact of NIHSS score in comparison to the other traditional risk factors on the functional outcome and 30-day mortality by mRS in the patients with acute ischemic stroke. Materials and Methods: Patients with acute ischemic stroke and age more than 18 years were included. Their admission NIHSS score and the 30-day mRS were analyzed. Patients were divided into two groups as survivors and non-survivors. Results: The mean age of survivors and non-survivors was 59.77 ± 10.99 and 65.58 ± 6.67 years, respectively. The NIHSS score on day 1 for non-survivors was 21.21 ± 8.21, and almost half of this score was seen in survivors. The NIHSS score on day 1 had a significant association with mortality with a relative risk of 0.79 (95% CI = 0.70–0.89). The NIHSS score has 73.7% sensitivity and 74.1% specificity with cutoff value of 15.5 for discriminating the outcome of ischemic stroke. Conclusion: The NIHSS and mRS scales are simple, validated, easily applicable, and reliable tools for assessing the mortality and the functional outcome of ischemic stroke patients.

Objectives: The increasing prevalence of coronary artery disease [CAD] poses worrying statistics. Atherosclerosis of coronary vessels is the main culprit for the spectrum of CAD especially acute coronary syndrome. Atherosclerosis is regarded as a consequence of inflammatory changes in the coronaries. Our study aimed to assess the role of risk factors and inflammatory markers with acute ST-elevation myocardial infarction [STEMI]. Methods: 100 patients with ST-elevation Myocardial infarction [STEMI] and 100 age and sex matched controls were included in the study. A history of risk factors like smoking, hypertension, diabetes and hypertension was noted. A venous blood sample was obtained for analysis of inflammatory markers. The data thus obtained was statistically analyzed. Results: The cases had a significant number of risk factors such as smoking, hypertension, and diabetes mellitus, previous history of CAD, increased body mass index [BMI], and raised high sensitive C-reactive protein [hs-CRP]. Patients with anterior myocardial infarction were older and had hypertension and diabetes mellitus. Patients with inferior myocardial infarction had high BMI, raised erythrocyte sedimentation rate [ESR] and alcoholism. Smokers, patients with diabetes mellitus, high total cholesterol, Low-density lipoprotein [LDL] cholesterol, and hs-CRP were more prone to complications. Conclusions: Patients with a greater number of risk factors and raised inflammatory markers were at high risk of STEMI and its complications. An approach to control the modifiable risk factors like obesity and lifestyle changes can reduce the disease burden.

Alzheimer’s disease is the most common type of dementia which has both cognitive and non-cognitive disabilities. Recent research has proved that sleep deprivation and insomnia have been related to the pathophysiology of Alzheimer's disease and would influence the symptoms and progression of the disease. We look at the current research that supports the idea that the lack of sleep relates to cognitive decline and dementia, with an emphasis on Alzheimer's disease. We integrated the various possible mechanisms of sleep deprivation leading to Alzheimer’s disease and cognitive decline. The role of neuroinflammation, generation of reactive oxidative species and sleep disturbances play a central role in tau generation and Aβ deposition. An approach to manage sleep changes can widely prevent the cognitive decline of Alzheimer’s disease.
