Context Nephrotoxicity is a renal dysfunction that arises from direct exposure to environmental chemicals or as a side effect of therapeutic drugs. Boerhaavia diffusa Linn. (Nyctaginaceae), Rheum emodi Wall. Ex. Meissn. (Polygonaceae), Nelumbo nucifera Gaertn. (Nelumbonaceae) and Crataeva nurvala Buch-Ham. (Capparidaceae) are well-recognized medicinal plants of Indian traditional system of medicine used for kidney disorders.Objectives The present investigation was undertaken to develop a chromatographically characterized polyherbal combination and to evaluate its nephroprotective activity.Materials and methods Roots of B. diffusa and R. emodi, flowers of N. nucifera and stem bark of C. nurvala were extracted by decoction using 70% ethanol. Response surface methodology (RSM) was used for the optimization of extraction parameters. Polyherbal combinations with different doses (150-300 mg/kg) were tested against methotrexate-induced nephrotoxicity in Wistar rats.Results The optimized extract contained 27% phenols and 15% flavonoids, which showed 75% 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging potential. Based on the retention time of high-performance liquid chromatography (HPLC) analysis, 17 out of 122 constituents were found common in all extracts and combinations. Two combinations showed significantly higher (p ≤ 0.05) DPPH scavenging potential and xanthine oxidase inhibition. The half maximal inhibitory concentration (IC50) of the best combination for DPPH scavenging and xanthine oxidase inhibition were 80 and 74 µg/mL, respectively. Treatment of methotrexate-induced nephrotoxic rats with polyherbal combination significantly (p ≤ 0.05) improved the kidney function markers, oxidative stress markers and histological parameters.Discussion and conclusion The developed combination was found to be effective in nephrotoxicity; it can be explored further for the management of drug-induced nephrotoxicity and other chronic kidney diseases.Purpose To describe the prevalence and clinical findings of ocular tuberculosis (TB) in Human immunodeficiency virus (HIV) and systemic TB co-infected patients.Methods In this prospective, observational, non-comparative case series, we included HIV and systemic TB co-infected patients, who underwent a detailed ophthalmic and systemic evaluation.Results Of 85 patients, ocular tuberculosis was seen in eleven patients and their 16 eyes (12.9%). selleck chemicals Without the benefit of eye exam, the diagnosis of disseminated TB was missed in 5/52 (9.6%) and 2/25 (8%) of patients clinically assumed to have pulmonary and Extrapulmonary TB, respectively.Conclusion HIV patients with the disseminated TB have higher risk for ocular TB. As ocular symptoms are rare, still all of them need a detailed ocular examination to look for active ocular TB which will reclassify isolated pulmonary/extrapulmonary to disseminated TB warranting a detailed systemic examination.In December 2019, an outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection occurred in Wuhan, Hubei Province, China and spread across China and beyond. On February 12, 2020, WHO officially named the disease caused by the novel coronavirus as Coronavirus Disease 2019 (COVID-19). Since most COVID-19 infected patients were diagnosed with pneumonia and characteristic CT imaging patterns, radiological examinations have become vital in early diagnosis and assessment of disease course. To date, CT findings have been recommended as major evidence for clinical diagnosis of COVID-19 in Hubei, China. This review focuses on the etiology, epidemiology, and clinical symptoms of COVID-19, while highlighting the role of chest CT in prevention and disease control.

This study broadens knowledge on parasites associated with these hosts and the real impact of this association.Background Bovine orthopneumovirus, formerly known as bovine respiratory syncytial virus (BRSV), is frequently associated with bovine respiratory disease (BRD).Aim To perform the molecular characterization of the G and F proteins of Brazilian wild-type BRSV strains derived from bovine respiratory infections in both beef and dairy cattle.Materials and Methods Ten BRSV strains derived from a dairy heifer rearing unit (n = 3) in 2011 and steers of three other feedlots (n = 7) in 2014 and 2015 were analyzed. For the BRSV G and F partial gene amplifications, RT-nested-PCR assays were performed with sequencing in both directions with forward and reverse primers used.Results The G gene-based analysis revealed that two strains were highly similar to the BRSV sequences representative of subgroup III, including the Bayovac vaccine strain. However, the remaining seven Brazilian BRSV strains were diverse when compared with strains representative of the BRSV I to VIII subgroups. The central hydrophobic region of the Brazilian BRSV G gene showed the replacement of conserved cysteines and other residues of importance to antibody reactivity. The deduced F gene amino acid sequences from the Brazilian BRSV strains showed changes that were absent in the representative sequences of the known subgroups. Viral isolation on the nasopharyngeal swab suspensions failed to isolate BRSV.Conclusion Results suggest that these strains represent a putative new subgroup of BRSV with mutations observed in the immunodominant region of the G protein. However, further studies on these Brazilian BRSV strains should be performed to establish their pathogenic potential.Gender inequality in the form of gender-based violence manifests throughout the course of women's lives but has a particularly unique impact at end of life. We sampled 26 patients and 14 caregivers for this qualitative critical ethnographic study. The study purpose was to describe the lived experience of female palliative care patients in rural Malawi and their caregivers. The specific aims were to (i) analyse physical, spiritual and mental health needs and (ii) guide best healthcare practice. The study was informed by feminist epistemology, which drew us to an analysis focused on how gender inequality and gender-based violence affect the care of those with terminal illness. In this article, based on our findings, we demonstrate how gender inequality manifests through the intersecting gendered vulnerabilities of patients and their caregivers in rural Malawi. The findings specifically provide insight into the gendered nature of care work and how the gendered life trajectories of both patients and caregivers intersect to impact the health and well-being of both groups.
