    Abstract In the past, large earthquakes caused the collapse of infrastructure and killed thousands of people in Pakistan, a seismically active region. Therefore, the seismic assessment of infrastructure is a dire need that can be done using the fragility analysis. This study focuses on the fragility analysis of school buildings in Muzaffarabad district, seismic zone-4 of Pakistan. Fragility curves were developed using incremental dynamic analysis (IDA); however, the numerical analysis is computationally time-consuming and expensive. Therefore, soft computing techniques such as Artificial Neural Network (ANN) and Gene Expression Programming (GEP) were employed as alternative methods to establish the fragility curves for the prediction of seismic performance. The optimized ANN model [5-25-1] was used. The feedforward backpropagation network was considered in this study. To achieve a reliable model, 70% of the data was selected for training and 15% for validation and 15% of data was used for testing the model. Similarly, the GEP model was also employed to predict the fragility curves. The results of both ANN and GEP were compared based on the coefficient of determination,

    Abstract Objective: The objective of this study was to identify the effect of nurse-led pre-operative education in minimizing the level of anxiety among patients waiting for Coronary Artery Bypass Grafting.
    Methods: This experimental study was accomplished at National Institute of Cardiovascular Diseases. Out of 136, there were 80 patients identified with the presence of anxiety using AKUADS 4 to 6 weeks before CABG. Data were collected by the primary researcher from July 2016 to December 2016. Patients with anxiety were divided into experimental and non-experimental groups. After pre-operative education to the experimental group, patients from both groups were re-assessed for anxiety level one week before CABG.
    Results: Data were assessed through non-parametric Wilcoxon sign ranked and Mann Whitney tests. It was found that anxiety reduced significantly in post-assessment among experimental group participants. No significant difference was found for pre-anxiety assessment between experimental and non-experimental groups. It was noted that post assessment anxiety differed significantly between experimental and non-experimental groups.
    Conclusion: Pre-operative education was found effective to decrease level of anxiety among patients waiting for CABG. There was no significant difference between pre and post assessment among patients from non-experimental group.

    Abstract Background: The most common cause of acute urinary retention in men over 50 is benign prostate enlargement (BPE). Following the urethral catheterization, a trial without a catheter (TWOC) under the cover of alpha-blockers is given. The timing of TWOC varies from Day 3 to Day 7 of the retention episode. There is a need to study the improvement in the success rate of TWOC with the increasing number of days of catheterization.
    Objective: To measure the success rate of TWOC in acute urinary retention due to benign prostatic enlargement with increasing days of catheterization.
    Method: The study was conducted in Social Security Teaching Hospital Lahore. Patients who presented with acute urinary retention due to benign prostatic enlargement were catheterized and given alpha-blockers. The patients were divided into two groups, one group having TWOC after three days and the other having TWOC after seven days. The success rate of TWOC was calculated and compared in the two groups. All patients included in the study had the first episode of acute retention with a moderately enlarged prostate and no element of second pathology or neurological deficit.
    Results: A total of 48 patients were included in the study, divided into two groups of 24 patients each. In the first group who underwent TWOC after seven days of catheterization, 15 out of 24 patients had successful TWOC with a success rate of 62.5%. In the second group of 24 patients, who had TWOC after three days of catheterization, only 11 patients had successful TWOC with a success rate of 45.8%.
    Conclusion: There was a marked improvement in the success rate of TWOC with increasing days of catheterization after an acute retention episode, secondary to BPE.

    Abstract Objective: To identify the prevalence and predictors of sarcopenia in cirrhotic patients.
    Methods: This observational, cross-sectional study was conducted at the National Institute of Liver and Gastrointestinal Diseases, Karachi, from January 30 to July 31, 2021, and comprised cirrhotic patients of either gender between aged 18-60 years. Clinical and laboratory data was recorded for each patient. Body weight was adjusted for ascites. Sarcopenia was determined based on the Asian Working Group for Sarcopenia-2019 guideline via hand grip strength and chair standing. Independent predictors for sarcopenia were identified. Data was analysed using SPSS 26.
    Results: Out of 434 cirrhotic patients assessed, 386(89%) were enrolled. Of them, 237(61.4%) were males, 149(38.6%) were females, 327(84.7%) were aged >45 years and 201(52.1%) had moderate professional activity. Sarcopenia was detected in 314(81.3%) patients; 185(59%) males and 129(41%) females. Age, chair exercise and hand grip scores as well as haemoglobin, albumin and potassium levels were significantly associated with sarcopenia (p<0.05).
    Conclusion: Sarcopenia was found to be very common in patients with cirrhosis. Increasing age, concomitant comorbidities, and presence of liver decompensation increased the risk of sarcopenia.

    Abstract Hypothesis: The bacteria suspended in pure water self-assemble into unique patterns depending on bacteria-bacteria, bacteria-substrate and bacteria-liquid interactions. The physical forces acting on bacteria vary based on their respective spatial location inside the droplet cause an assorted magnitude of physical stress. The shear and dehydration induced stress on pathogens(bacteria) in drying bio-fluid droplets alters the viability and infectivity. Experiments: We have investigated the flow and desiccation-driven self-assembly of Klebsiella pneumoniae in the naturally evaporating sessile droplets. Klebsiella pneumoniae exhibits extensive changes in its morphology and forms unique patterns as the droplet dries, revealing hitherto unexplored rich physics governing its survival and infection strategies. Self-assembly of bacteria at the droplet contact line is characterized by order-to-disorder packing transitions with high packing densities and excessive deformations (analysed using scanning electron microscopy and atomic force microscopy). In contrast, thin-film instability-led hole formation at the center of the droplet engenders spatial packing of bacteria analogous to honeycomb weathering. Findings: Self-assembly favors the bacteria at the rim of the droplet, leading to enhanced viability and pathogenesis on the famously known “coffee ring” of the droplet compared to the bacteria present at the center of the droplet residue. Mechanistic insights gained via our study can have far-reaching implications for bacterial infection through droplets, e.g., through open wounds.

    Abstract Deposits of biofluid droplets on surfaces (such as respiratory droplets formed during an expiratory) are composed of water-based salt-protein solution that may also contain an infection (bacterial/viral). The final patterns of the deposit formed and bacterial aggregation on the deposits are dictated by the fluid composition and flow dynamics within the droplet. This work reports the spatio-temporal, topological regulation of deposits of respiratory fluid droplets and control of bacterial aggregation by tweaking flow inside droplets using non-contact vapor-mediated interactions. Desiccated respiratory droplets form deposits with haphazard multiscale dendritic, cruciform-shaped precipitates when evaporated on a glass substrate. However, we showcase that short and long-range vapor-mediated interaction between the droplets can be used as a tool to control these deposits at nano-micro-millimeter scales. We morphologically control hierarchial dendrite size, orientation and subsequently suppress cruciform-shaped crystals by placing a droplet of ethanol in the vicinity of the biofluid droplet. Active living matter in respiratory fluids like bacteria is preferentially segregated and agglomerated without its viability and pathogenesis attenuation. The nucleation sites can be controlled via preferential transfer of solutes in the droplets; thus, achieving control over crystal occurrence, growth dynamics, and the final topology of the deposit. For the first time, we have experimentally presented a proof-of-concept to control the aggregation of live active matter like bacteria without any direct contact. The methodology can have ramifications in biomedical applications like disease detection and bacterial segregation.

    Abstract Turmeric exhibits a big promise as a therapeutic agent in the management of oral submucous fibrosis (OSMF). The primary aim of our study is to synthesize the evidence of the use of turmeric/curcumin in the management of OSMF. The secondary goal of this study is to assess the limitations of previous studies to identify gaps in evidence for future research and give an evidence-based recommendation regarding the usage of turmeric/curcumin for OSMF patients and outline the direction of research. A comprehensive search of PubMed, Web of Science, Scopus, Cochrane Library database, Google Scholar, clinical trial registries, and hand searching was conducted from inception until December 2018. This systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (guidelines). In this review, 11 articles were selected for qualitative analysis and 3 out of 11 were selected for meta-analysis. Of these 11 studies, involving 428 patients, 7 were randomized control trials (RCTs), 1 was a nonrandomized trial, and 3 were observational studies. Turmeric was found to be effective in reducing signs and symptoms of OSMF in all 11 studies. All the studies included in this review have reported improvement in mouth opening after treatment with turmeric formulations. This could also be concluded from the meta-analysis of three RCTs. Similar improvement in tongue protrusion, burning sensation, and cheek flexibility has been reported. The lack of reliable evidence for the effectiveness of turmeric for the management of OSMF is illustrated by the paucity and poor methodological quality of studies retrieved for this review. We recommend that RCTs are needed using larger sample size with longer duration follow-up with special attention to the recurrence of signs and symptoms.
