Changing histological spectrum of adult nephrotic syndrome in comparison to previous study: single centre analysis

Background: Glomerular diseases are an important cause of chronic renal failure in developing countries. The spectrum of diseases causing nephrotic syndrome is changing globally in the last few decades. Methods: Patients in the age group 18-60 years with nephrotic syndrome were consecutively included in the study. Renal biopsies were performed in all patients and were subjected to light microscopy, immunofluorescence (IF) and electron microscopy (EM). Results: 189 patients (67% males) were included in the study. The mean age was 43 years. Primary glomerular diseases accounted for 92.5% of cases while lupus nephritis was the most common secondary glomerular disease. Focal segmental glomerulosclerosis (FSGS) accounted for 28.6% of primary glomerular diseases making it the most common cause of nephrotic syndrome. It was followed by membranous glomerulonephritis (MGN) in 13.2%, membranoproliferative glomerulonephritis in 11.2%, diffuse proliferative glomerulonephritis in 10.6% and minimal change disease in 9.5%. Conclusions: The biopsy diagnosis of FSGS has increased considerably in last few decades and it is now the most common cause of nephrotic syndrome in adults in North India. MGN is the most common lesion in patients over 40 years of age

Cardiovascular profile of vasculitis patients at tertiary care center

Background: The vasculitides are a heterogenous group of conditions characterized by blood vessel inflammation and necrosis. Vasculitides are relatively uncommon conditions whose etiology is still poorly understood. Objective of the research was to study the cardiovascular profile of vasculitis patients at a tertiary care centre.Methods: The present hospital based observational study was conducted in the department of internal medicine, Sher-i-Kashmir Institute of Medical Sciences (SKIMS), Srinagar, Jammu and Kashmir, India. The study had two parts: retrospective and prospective. In the retrospective part, all patients of vasculitis who were admitted or evaluated in outpatient department (OPD) from March 2012 to September 2018, were enrolled for the analysis. In the prospective part, all patients of vasculitis admitted or evaluated in OPD from October 2018 to May 2020 were enrolled for study.Results: Out of total 77 patients studied, 39 (50.6%) were prospective cases and 38 (49.4%) cases were of retrospective nature. Normal echocardiographic and electrocardiography (ECG) findings were seen in majority of all three groups. Computed tomography (CT) angio shows involvement of right subclavian artery in 9 (40.9%) patients, 8 (36.4%) patients had involvement of left subclavian artery, 6 (27.3%) patients had involvement of arch of aorta, CT angio was suggestive of involvement left common carotid artery 5 patients, 2 patients each had involvement of celiac artery, bilateral iliac, ascending aorta, normal CT angio findings. Arterial Doppler was suggestive of involvement of right common carotid artery (CCA) and left CCA in 4 (30.8%) patients each, right superior cerebellar artery (SCA) involvement in 3 (23.1%) patients, left SCA involvement in 4 (30.8%) patients, left right brachiocephalic artery (RBA), right RA and B/L UA involvement was observed in 1 (7.7%) patient each.Conclusions: The association between cardiovascular disease and a vasculitis is well documented. our study discusses the association between cv disease and vasculitis

Desempenho agronômico e variabilidade genética em genótipos de couve

O objetivo deste trabalho foi avaliar o desempenho agronômico de acessos de couve e estimar os parâmetros genéticos e a correlação entre características de interesse para o melhoramento. O experimento foi realizado em delineamento de blocos ao acaso, com 30 genótipos de couve, entre os quais, três cultivares comerciais, de diferentes empresas. Foram utilizadas quatro repetições, com cinco indivíduos por parcela. Verificou-se variabilidade genética entre os genótipos, com predominância dos efeitos genéticos sobre os ambientais, o que indica a possibilidade de se obterem ganhos genéticos representativos com o melhoramento. As características importantes para o melhoramento da espécie foram: comprimento e largura de folha, diâmetro de pecíolo, área foliar, altura de planta, número de brotações e massa de folhas secas. Os genótipos comerciais apresentaram menor área foliar, massa de matéria seca de folhas, altura de planta, comprimento e largura de folha, comprimento de pecíolo, e número de brotações e de folhas comerciais

Mortality and pulmonary complications in patients undergoing surgery with perioperative sars-cov-2 infection: An international cohort study

Background The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (740%) had emergency surgery and 280 (248%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (261%) patients. 30-day mortality was 238% (268 of 1128). Pulmonary complications occurred in 577 (512%) of 1128 patients; 30-day mortality in these patients was 380% (219 of 577), accounting for 817% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 175 [95% CI 128-240], p<00001), age 70 years or older versus younger than 70 years (230 [165-322], p<00001), American Society of Anesthesiologists grades 3-5 versus grades 1-2 (235 [157-353], p<00001), malignant versus benign or obstetric diagnosis (155 [101-239], p=0046), emergency versus elective surgery (167 [106-263], p=0026), and major versus minor surgery (152 [101-231], p=0047). Interpretation Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
