Simulation-Based Teaching and Learning in Respiratory Care Education: A Narrative Review.

Simulation-based pedagogy has become an essential aspect of healthcare education. However, there is a significant gap in the literature regarding the application of simulation-based modalities in respiratory care education. This review aims to address this gap by providing insight into the theory and current uses of simulation, its effectiveness in respiratory care education, and strategies to enhance faculty development. The study utilizes a narrative synthesis approach to review relevant literature and provide a comprehensive understanding of the topic. The research involved comprehensive searches of electronic databases, including PubMed and Google Scholar, to identify relevant literature, encompassing original articles, reviews, and other pertinent content, focusing on simulation-based teaching and learning in respiratory care education published between 1990 and 2022. Findings suggest that simulation-based education is an effective tool for improving respiratory care education and can enhance the clinical skills of learners. The study concludes by discussing the future of simulation in respiratory care education and the potential benefits it may offer.

A silent march-Post covid fibrosis in asymptomatics - A cause for concern?

We report a case series of patients presenting with undiagnosed pulmonary fibrosis as a primary manifestation. On evaluation, after excluding other causes, the fibrosis was attributed to asymptomatic or mild COVID illness in the past. This case series serves to highlight the difficulties posed to clinicians while evaluating pulmonary fibrosis in the post-COVID era, more so in mild to asymptomatic COVID-19. The intriguing possibility of fibrosis setting even in mild to asymptomatic COVID is discussed.

Mesoporous aluminum impregnated rubber seed shell waste enriched with calcium as adsorbent material for the removal of microbial DNA in aqueous solution.

Water contamination by pathogens and diseases induced by these pathogens is a major water quality issue all over the world. Poor public health has been linked to tap water polluted with DNA harboring antibiotic resistance genes sequence. According to HSAB concept, surface modification of rubber seed shell waste with alumina (AIRSS) as novel agro-waste adsorbent creates more active surface constituents for DNA adsorption. The proximate, ultimate and EDAX analysis provides the percentage levels of ash concentration, volatile, moisture and fixed carbon content, elemental composition present in the adsorbent. The structural features of AIRSS were determined using FT-IR, SEM and XRD. In order to improve reaction conditions, the effect of pH, temperature, adsorbent amount, and reaction time is also examined. The highest percent of DNA removal (92.5%) was achieved at the optimum conditions: 2 g/L at pH 4, contact time 120 minutes as compared to the conventional methods. The DNA adsorbs onto the surface of AIRSS through physical (vander Waals force) and chemical interactions, as demonstrated by kinetics and spectroscopic analyses. Changes in enthalpy (H), free energy (G), and entropy (S) indicate that adsorption is a spontaneous and exothermic process, according to thermodynamic parameters. The results of the experiments showed that the prepared AIRSP adsorbent could be used to remove DNA from water. The efficacy of AIRSS for the removal of DNA has decreased after nine months of storage and use. Low pH and the presence of AIRSS improved DNA-AIRSS adsorption, according to our findings.

Predictors and Outcomes of Postoperative Pulmonary Complications following Abdominal Surgery in a South Indian Population.

BACKGROUND: Postoperative pulmonary complications (PPC) following abdominal surgery are associated with increased morbidity and poorer outcomes. We prospectively examined risk factors associated with the development of PPC in patients undergoing abdominal surgery. AIMS: The primary outcome was to determine the association of predefined risk factors in the prediction of PPC after abdominal surgery. Secondary outcomes were evaluation of outcomes of PPC. SETTING AND DESIGN: This was a prospective study conducted in the gastrosurgical and urological units of a tertiary care referral hospital in patients undergoing abdominal surgery over a period of 6 months (November 2015-April 2016). MATERIALS AND METHODS: Relevant preoperative and intraoperative variables were recorded by the anesthesiologist in a pro forma provided. Postoperatively, data from the Intensive Care Unit (ICU) were collected from data sheets. PPC were defined according to preset criteria and outcomes of the patients including ICU stay, hospital stay, and mortality were noted. STATISTICAL ANALYSIS: Chi-square test was used to find the association of risk factors of PPC. Mann-Whitney test was used for continuous variables and McNemar's test for postoperative respiratory variables. A final regression analysis was performed with factors with significant association (P < 0.1). RESULTS: One hundred and fifty patients were included, and 24 patients (16%) developed PPC as defined by our criteria. Emergency surgery (44.4% of PPC) and cardiac comorbidity (23.9% of PPC) were significant associations for pulmonary complications. The length of ICU and hospital stay (LOICU, LOHS) and mortality were higher in the group with pulmonary complications (P < 0.001). CONCLUSIONS: Emergent surgery and cardiac comorbidities were independent predictors for the development of PPC. PPC are associated with increased LOHS, LOICU stay, and mortality.
