Hemorrhoidal disease (HD) is the most common proctological disease, with an estimated prevalence rate of 4.4%, and a peak in individuals between 45 and 65years of age. This study was done to evaluate whether Lian-Zhi-San (LZS), a clinically used anti-hemorrhoidal ointment could alleviate the inflammatory injury, with its associated changes of inflammatory cytokines and morphology of anorectal tissues, in an experimental model of HD in rats.
HD was induced by croton oil preparation (COP) applied to the anorectal region. Rats were then treated with cotton swabs soaked in LZS ointment, water or white vaseline, twice a day for 7 d. At the end of the experiment, HD was evaluated by measuring hemorrhoidal and biochemical parameters along with histopathological observations.
In this study, COP induced a significant increase in the macroscopic severity score, anorectal coefficient and Evans blue extravasation, compared to normal rats. Additionally, it greatly enhanced the expression and secretion levels of some important inflammation-related cytokines along with marked histological damage, compared to normal rats. Rats treated with LZS ointment experienced significantly ameliorated Evans blue extravasation (P<0.05), decreased macroscopic severity score (0.86±0.14 vs. 1.65±0.16) and the anorectal coefficient (P<0.01); its use also attenuated tissue damage and inhibited the expression and secretion levels of inflammation-related cytokines (interleukin-1β, interleukin-6 and tumor necrosis factor-α).
This study validates a preliminary understanding of the use of LZS ointment to treat inflammatory factors and tissue damage in an experimental model of HD in rats.

Standard Precautions have been demonstrated to limit infection transmission in the healthcare setting. Despite their mandated use, adherence by healthcare professionals remains suboptimal. A nursing curriculum embedding infection prevention and control is essential in equipping future healthcare professionals with the skills and knowledge to improve patient safety. There are no psychometrically-validated tools that specifically assess influences on nursing students' adherence to standard precautions.
The aim in this study was to determine the reliability and validity of the five-factor Factors Influencing Adherence to Standard Precautions within a sample of undergraduate nursing students studying at one Australian University.
Data from 321 participants were used to test the 5 factors structure, using Confirmatory Factor Analysis. The goodness of fit indices did not support adequate fit of the data and the data were submitted to a random split-half sample factor analysis process. A four-factor solution wtion.Transcatheter Mitral Valve Repair (TMVr) offers clinically significant benefit to select symptomatic patients with severe mitral regurgitation (MR). We conducted a systematic review and meta-analysis of clinical trials and observational studies to identify the effect of pre-procedural Chronic Kidney disease (CKD) on short-term mortality in TMVr. We found CKD is a predictor of 30-day mortality in patients undergoing TMVr. Specifically, a GFR less then 30 mL/min conveys a significant increase in 30-day mortality. This is significant for patient selection, prognostication, as well as identifies an area of need for further research. SUMMARY FOR ANNOTATED TABLE OF CONTENTS A systematic review and meta-analysis looking at short-term mortality in patients undergoing Transcatheter Mitral Valve Repair with chronic kidney disease. Findings show severe renal disease is associated with increased 30-day mortality.Early treatment with combination antiretroviral therapy (cART) has improved survival of children perinatally infected with HIV into adolescence. This population is at risk of long term complications related to HIV infection, particularly chronic respiratory disease. Limited data on chest imaging findings in HIV-infected adolescents, suggest that the predominant disease is of small and large airways predominantly bronchiolitis obliterans or bronchiectasis. Single cases of emphysema have been reported. Lung fibrosis, lymphocytic interstitial pneumonitis, post tuberculous apical fibrocystic changes and malignancies do not feature in this population. Bromelain datasheet Chest radiograph (CXR) is easily accessible and widely used, especially in resource limited settings, such as sub Saharan Africa, where the greatest burden of HIV disease occurs. Lung ultrasound has been described for the diagnosis of pneumonia in children, pulmonary oedema and interstitial lung disease [1-3]. The use of this modality in chronic respiratory disease in adolescents where the predominant finding is small airway disease and bronchiectasis has however not been described. CXR is useful to evaluate structural/post infective changes, parenchymal opacification and nodules, hyperinflation or extensive bronchiectasis. CXR however, is inadequate for diagnosing small airway disease, for which high resolution computed tomography (HRCT) is the modality of choice. Where available, low dose HRCT should be used early in the course of symptomatic disease in adolescents and for follow up in children who are non responsive to treatment or clinically deteriorating. This article provides a pictorial review of the spectrum of CXR and HRCT imaging findings of chronic pulmonary disease in perinatally HIV-infected adolescents on cART and guidelines for imaging.
Surgical trainees with significant underperformance require formal support to return to an expected standard, termed remediation. The aim of this scoping review was to define remediation interventions, approaches, and contexts.
Following scoping review protocols, we set out to identify the evidence-base for remediation of surgical trainees, outline key concepts and uncover areas to stimulate further research.
From a screen of 80 articles, 24 reported on remediation of surgical trainees. Most were from medical journals (n = 21, 88%) and published in the United States (n = 20, 83%). Ten articles (41%) reported outcomes of remediation of a trainee cohort and 7 (19%) were survey reports from surgical directors. The remainder were a mix of commentaries, editorials or reviews. Thirteen articles (54%) described trainees with deficiencies in multiple competencies, 8 articles (33%) had a singular focus on academic performance, and 1 article (3%) on technical skills. All articles used targeted individualized remediation strategies, a range of intervention methods (some multimodal) and recommended a 6- to 12-month period of remediation (n = 7, 29%).
