Abstract
Background Subclinical hypothyroidism (SCH) is associated with major adverse cardiovascular events. Despite the recognized negative impact of SCH on cardiovascular health, research on cardiac postoperative outcomes with SCH has yielded conflicting results, and patients are not currently treated for SCH before cardiac surgery procedures. Methods We performed a study-level meta-analysis on the impact of SCH on patients undergoing nonurgent cardiac surgery, including coronary artery bypass grafting and valve and aortic surgery. The primary outcome was operative mortality. Secondary outcomes were hospital length of stay (LOS), intensive care unit (ICU) stay, postoperative atrial fibrillation (POAF), intra-aortic balloon pump (IABP) use, renal complications, and long-term all-cause mortality. Results Seven observational studies, with a total of 3445 patients, including 851 [24.7%] diagnosed with SCH and 2594 [75.3%] euthyroid patients) were identified. Compared to euthyroid patients, the patients with SCH had higher rates of operative mortality (odds ratio [OR], 2.57; 95% confidence interval [CI], 1.09-6.04; P = .03), prolonged hospital LOS (standardized mean difference, 0.32; 95% CI, 0.02-0.62; P = .04), a higher rate of renal complications (OR, 2.53; 95% CI, 1.74-3.69; P < .0001), but no significant differences in ICU stay, POAF, or IABP use. At mean follow-up of 49.3 months, the presence of SCH was associated with a higher rate of all-cause mortality (incidence rate ratio, 1.82; 95% CI, 1.18-2.83; P = .02). Conclusions Patients with SCH have higher operative mortality, prolonged hospital LOS, and increased renal complications after cardiac surgery. Achieving and maintaining a euthyroid state prior to and after cardiac surgery procedures might improve outcomes in these patients.

Abstract
OBJECTIVES Midline sternotomy is the main surgical access for cardiac surgeries. The most prominent complication of sternotomy is sternal wound infection (SWI). The use of a thorax support vest (TSV) that limits thorax movement and ensures sternal stability has been suggested to prevent postoperative SWI. METHODS We performed a meta-analysis to evaluate differences in clinical outcomes with and without the use of TSV after cardiac surgery in randomized trials. The primary outcome was deep SWI (DSWI). Secondary outcomes were superficial SWI, sternal wound dehiscence, and hospital length of stay (LOS). A trial sequential analysis was performed. Fixed (F) and random effects (R) models were calculated. RESULTS A total of 4 studies (3820 patients) were included. Patients who wore the TSV had lower incidence of DSWI [odds ratio (OR) = F: 0.24, 95% confidence interval (CI), 0.13-0.43, P < 0.01; R: 0.24, 0.04-1.59, P = 0.08], sternal wound dehiscence (OR = F: 0.08, 95% CI, 0.02-0.27, P < 0.01; R: 0.10, 0.00-2.20, P = 0.08) and shorter hospital LOS (standardized mean difference = F: -0.30, -0.37 to -0.24, P < 0.01; R: -0.63, -1.29 to 0.02, P = 0.15). There was no difference regarding the incidence of superficial SWI (OR = F: 0.71, 95% CI, 0.34-1.47, P = 0.35; R: 0.64, 0.10, 4.26, P = 0.42). The trial sequential analysis, however, showed that the observed decrease in DSWI in the TSV arm cannot be considered conclusive based on the existing evidence. CONCLUSIONS This meta-analysis suggests that the use of a TSV after cardiac surgery could potentially be associated with a reduction in sternal wound complications. However, despite the significant treatment effect in the available studies, the evidence is not solid enough to provide strong practice recommendations.

Abstract
During the month of Ramadan, which falls on the ninth month of the Hijri Calendar, Muslims are obligated to observe religious fasting. The goal of the study was to examine the impact of fasting on various blood parameters, specifically zinc, magnesium, pre-haptoglobin-2, serum copper, total cholesterol, and HDL-cholesterol levels. In a study, a group of volunteers consisting of 20 men and 10 women agreed to partake in the fast, abstaining from food and drink for approximately 14-15 hours each day. The researchers collected two blood samples from each participant, one before the start of Ramadan fasting and another after 29 days of fasting, serum was separated and analysed for specified parameters. Serum zinc levels showed a significant (p<0.05) decrease after fasting. On the other hand, serum magnesium levels exhibited a significant (p<0.05) increase, Regarding pre-haptoglobin-2, there was a small, insignificant increase observed after 29 days of fasting. However, the study did not identify any significant changes in serum copper, total cholesterol, or HDL-cholesterol levels. Based on these findings, the study concludes that Ramadan fasting may necessitate zinc supplementation or an increase in the consumption of zinc-rich foods. Furthermore, it suggests a decrease in the intake of high-fat foods. These recommendations aim to counteract the observed decrease in serum zinc levels during fasting.

Abstract
OBJECTIVE A scoping review of the literature was conducted to identify intraoperative artificial intelligence (AI) applications for robotic surgery under development and categorize them by (1) purpose of the applications, (2) level of autonomy, (3) stage of development, and (4) type of measured outcome. BACKGROUND In robotic surgery, AI-based applications have the potential to disrupt a field so far based on a master-slave paradigm. However, there is no available overview about this technology's current stage of development and level of autonomy. METHODS MEDLINE and EMBASE were searched between January 1, 2010 and May 21, 2022. Abstract screening, full-text review, and data extraction were performed independently by 2 reviewers. The level of autonomy was defined according to the Yang and colleagues' classification and stage of development according to the Idea, Development, Evaluation, Assessment, and Long-term follow-up framework. RESULTS One hundred twenty-nine studies were included in the review. Ninety-seven studies (75%) described applications providing Robot Assistance (autonomy level 1), 30 studies (23%) application enabling Task Autonomy (autonomy level 2), and 2 studies (2%) application achieving Conditional autonomy (autonomy level 3). All studies were at Idea, Development, Evaluation, Assessment, and Long-term follow-up stage 0 and no clinical investigations on humans were found. One hundred sixteen (90%) conducted in silico or ex vivo experiments on inorganic material, 9 (7%) ex vivo experiments on organic material, and 4 (3%) performed in vivo experiments in porcine models. CONCLUSIONS Clinical evaluation of intraoperative AI applications for robotic surgery is still in its infancy and most applications have a low level of autonomy. With increasing levels of autonomy, the evaluation focus seems to shift from AI-specific metrics to process outcomes, although common standards are needed to allow comparison between systems.

Abstract
PURPOSE/OBJECTIVE(S) Developments of automated systems for brain metastasis (BM) detection and segmentation from MRI for assisting early detection and stereotactic radiosurgery (SRS) have been reported but most based upon relatively small datasets from single institutes. This work aims to develop and evaluate a system using a large multi-institutional dataset, and to improve both identification of small/subtle BMs and segmentation accuracy of large BMs. MATERIALS/METHODS A 3D U-Net system was trained and evaluated to detect and segment intraparenchymal BMs with a size > 2mm using 1856 MRI volumes from 1791 patients treated with SRS from seven institutions (1539 volumes for training, 183 for validation, and 134 for testing). All patients had 3D post-Gd T1w MRI scans pre-SRS. Gross tumor volumes (GTVs) of BMs for SRS were curated by each institute first. Then, additional efforts were spent to create GTVs for the untreated and/or uncontoured BMs, including central reviews by two radiologists, to improve accuracy of ground truth. The training dataset was augmented with synthetic BMs of 3773 MRIs using a 3D generative pipeline. Our system consists of two U-Nets with one using small 3D patches dedicated for detecting small BMs and another using large 3D patches for segmenting large BMs, and a random-forest based fusion module for combining the two network outputs. The first U-Net was trained with 3D patches containing at least one BM < 0.1 cm3. For detection performance, we measured BM-level sensitivity and case-level false-positive (FP) rate. For segmentation performance, we measured BM-level Dice similarity coefficient (DSC) and 95-percentile Hausdorff distance (HD95). We also stratified performances based upon BM sizes. RESULTS For 739 BMs in the 134 testing cases, the overall lesion-level sensitivity was 0.870 with an average case-level FP of 1.34±1.92 (95% CI: 1.02-1.67). The sensitivity was >0.969 for the BMs >0.1 cm3, but dropped to 0.755 for the BMs < 0.1 cm3 (Table 1). The average DSC and HD95 for all detected BMs were 0.786 and 1.35mm. The worse performance for BMs > 20 cm3 was caused by a case with 83 cm3 GTV and artifacts in the MRI volume. CONCLUSION We achieved excellent detection sensitivity and segmentation accuracy for BMs > 0.1 cm3, and promising performance for small BMs (<0.1cm3) with a controlled FP rate using a large multi-institutional dataset. Clinical utility for assisting early detection and SRS planning will be investigated. Table 1: Per-lesion detection and segmentation performance stratified by individual BM size. N is the number of BMs in each category.

Abstract
The European Society of Organ Transplantation (ESOT) strives to promote equity, diversity, and inclusion (EDI) across all its activities. We surveyed the transplant community's experiences and perspectives regarding EDI within ESOT as an organization and its educational activities, and research in general. A total of 299 respondents completed the questionnaire. About half agreed that ESOT's Executive Committee, Council, and Sections/Committees are diverse and inclusive (51%) and that ESOT promotes EDI in its live and digital educational activities (54%). Forty percent of respondents agreed that scientific and clinical trials in the field of transplantation are diverse and inclusive. Despite the wide distribution of the survey, most of the respondents self-identified as White and were either physician or surgeon. However, the results contribute a unique insight into the experiences and perspectives of the transplantation community regarding EDI. Whilst ESOT is committed to the principles of EDI, perceptions and the high number of proposals show the apparent need to prioritize efforts to embed EDI across ESOT and transplantation science. These data should constitute a starting point for change and provide guidance for future efforts to promote EDI within the transplantation community.

Abstract
Background Current personal protective equipment (PPE) practices in UK intensive care units involve "sessional" use of long-sleeved gowns, risking nosocomial infection transmitted via gown sleeves. Data from the first wave of the COVID19 pandemic demonstrated that these changes in infection prevention and control protocols were associated with an increase in healthcare associated bloodstream infections. We therefore explored the use of a protocol using short-sleeved gowns with hand and arm hygiene to reduce this risk. Methods ICU staff were trained in wearing short-sleeved gowns and using a specific hand and arm washing technique between patients (experimental protocol). They then underwent simulation training, performing COVID-19 intubation and proning tasks using either experimental protocol or the standard (long-sleeved) control protocol. Fluorescent powder was used to simulate microbial contamination, detected using photographs under ultraviolet light. Teams were randomised to use control or experimental PPE first. During the simulation, staff were questioned on their feelings about personal safety, comfort and patient safety. Results Sixty-eight staff and 17 proning volunteers were studied. Experimental PPE completely prevented staff contamination during COVID-19 intubation, whereas this occurred in 30/67 staff wearing control PPE (p = .003, McNemar). Proning volunteers were contaminated by staff in 15/17 control sessions and in 1/17 with experimental PPE (p = .023 McNemar). Staff comfort was superior with experimental PPE (p< .001, Wilcoxon). Their personal safety perception was initially higher with control PPE, but changed towards neutrality during sessions (p < .001 start, 0.068 end). Their impressions of patient safety were initially similar (p = .87), but finished strongly in favour of experimental PPE (p < .001). Conclusions Short-sleeved gowns with hand and forearm cleansing appear superior to sessional long-sleeved gowns in preventing cross-contamination between staff and patients.

Total 3149 numbers of bats were found in eight biological spots visited; Baffa Doraha, Darband, Dadar, Jallu, Hazara University, Garhi Habibullah Chattar Plain and Jabori, in total 299 numbers of different species of trees including; Morus alba, Pinus raxburghi, Eucalyptus camaldulensis, Morus nigra, Grevillea robusta, Brousonetia papyrifera, Platanus orientalis, Ailanthus altissima, Hevea brasiliensis and Populus nigra. Morphometric features were measured and found vary according to sex of the bats. The average wing span, wing`s length from tip of wing to neck, from thumb to tip of wing and the body`s length from head and claws were recorded to be 102.98 cm, 49.07cm, 28.7 cm and 22.78 cm respectively in males while 93.67 cm, 44.83cm, 24.78cm and 22.78 cm respectively in female bats. Mean circumference of the body including wings and without wing were measured as 22.78 cm and 17.29 cm in males and that of female were 20.07 cm and 16.9 cm. Average length of thumb 3.64 cm, ear`s length 3.1 cm, snout 5.62cm, eye length were 1.07 cm for both sexes and length between the feet in extended position were16.3 cm. Generally different measurement of males bodies were found to be greater than female such as mean body surface area, mass, volume and pressure were found to be 2691.79 cm2, 855.7gm,1236.4 ml and 295.77 dyne/ c m 3 for male and 2576.46 cm2, 852.71gm,1207 ml and 290.2 dyne/ c m 3 respectively for female. While weight and density for both males and females bats were same with mean of 8.59 newton and 0.701 g/m3. Findings of current reports can add valued information in literature about bats, which can be used for species identification and conservation.

Abstract
Background Candida is a frequent respiratory tract colonizer. True candida pneumonia is rare and seen with predominance in immunosuppressed patients. Our aim is to document a previously unreported case of Candida pneumonia in a young and immunocompetent patient, highlighting, an unusual pathological manifestation of this infection in immunocompetent individuals. Case summary We report a previously healthy young lady who remained symptomatic with fever, cough and shortness of breath for three weeks duration despite treatment with extensive antibiotics regimen for community acquired pneumonia. She was eventually treated as a probable, rare case of candida pneumonia. The patient demonstrated a dramatic response to single antifungal treatment both clinically and biochemically within the first 24hrs of treatment. Candida albican was isolated on repetitive cultures form the sputum and bronchoalevolar lavage samples. The patient had negative blood cultures. Her HRCT scan revealed bilateral basal air space opacities with peri bronchovascular distribution and centrilobular nodules with branching pattern suggestive of tree in bud predominantly in lower lobes. Her endobronchial biopsies was mostly unremarkable apart from rare non-necrotizing granuloma. Conclusion Candida can rarely cause clinically significant pneumonia in immunocompetent patients and should be considered in the differential diagnosis of granulomatous lung disease.

Abstract
The world has been devastated facing the outbreak of a novel infectious disease known as Corona virus disease (COVID-19). This has been declared as a pandemic by the World Health Organization. The frontline health care workers, who are directly involved in the diagnosis, treatment and care of patients with COVID-19, are taking significant personal risks on their own health and those of their family members. Objectives of the study include establishing the physical, psychological and social impact experience by the healthcare workers serving in public hospitals of Bangladesh. This prospective cross-sectional observational study was carried out at Kuwait Bangladesh Friendship Government Hospital, the first Covid-19 designated hospital of Bangladesh between the 1st June and the 31st August, 2020. A total of 294 doctors, nurses, ward boys and ailed healthcare workers were included in this study via purposive sampling. The study found statistically significant (p value 0.024) difference of medical co-morbidities between Covid-19 positive and Covid-19 negative groups of health care professionals. Significant association was found between duration of work and presence during aerosol generating procedure with COVID infectivity of the study subjects. 72.8% respondents experienced public fear of contracting the virus from them and 69.0% noticed negative attitude of the society towards them. Eighty five percent (85.0%) did not get any community support during this pandemic crisis. The health care professionals engaged in COVID-19 treatment have been taking significant personal risk on their life in terms of physical, psychological and social perspective. Providing safeguard to the health care workers are integral components of public health measures for addressing the COVID-19 pandemic. Special interventions to promote their physical wellbeing and arrangement of adequate psychological training need to be immediately implemented to cope up this critical situation.

Abstract
BACKGROUND Endovascular intervention has become the first-line treatment of patients with abdominal aortic aneurysms (AAAs) or aortoiliac occlusive disease (AIOD). However, open abdominal aortic repair remains a valuable treatment option for patients who are younger, those with unfavorable anatomy, and patients for whom endovascular intervention has failed. The cohort of patients undergoing open repair has become highly selected; nevertheless, updated outcomes or patient selection recommendations have been unavailable. In the present study, we explored and compared the characteristics and postoperative outcomes of patients who had undergone open abdominal aortic repair from 2009 to 2018. METHODS Patients who had undergone open AAA (n = 9481) or AIOD (n = 9257) repair were collected from the National Surgical Quality Improvement Program database. The primary outcome was the 30-day mortality. The secondary outcomes included 30-day return to the operating room, total operative time, total hospital stay, and postoperative complications. Unmatched and matched differences between the two groups and changes over time were analyzed. Univariate and multivariate regression analyses were conducted to assess the risk factors predicting for 30-day mortality. RESULTS After propensity matching (n = 4980), those in the AIOD group had had a higher 30-day mortality rate (5.1% vs 4.1%; P = .021), a higher incidence of wound complications (7.4% vs 5.1%; P<.0001) and an increased 30-day return to the operating room (14.2% vs 9.1%; P < .0001). More open AIOD cases (P = .02) and fewer open AAA cases (P = .04) had been treated in the second half of the decade than in the first. The factors associated with an increased odds of 30-day mortality included advanced age, American Society of Anesthesiologists score ≥III, functional dependence, blood transfusion <72 hours before surgery, weight loss in previous 6 months, and a history of chronic obstructive pulmonary disease. CONCLUSIONS From 2009 to 2018, the number of open AAA repairs decreased and the proportion of open abdominal AIOD cases increased. Open AIOD surgery was associated with higher 30-day mortality, increased return to the operating room, and increased wound complications vs open AAA repair. Multiple risk factors increased the odds for perioperative mortality. Thus, open abdominal aortic repair should be selectively applied to patients with fewer risk factors.

Abstract
DECIDE-AI is a new, stage-specific reporting guideline for the early and live clinical evaluation of decision-support systems based on artificial intelligence (AI). It answers a need for more attention to the human factors influencing clinical AI performance and more transparent reporting of clinical studies investigating AI systems. Given the rapid expansion of AI systems and the concentration of related studies in radiology, these new standards are likely to find a place in radiological literature in the near future. This review highlights some of the specificities of AI as complex intervention, why a new reporting guideline was needed for early stage, live evaluation of this technology, and how DECIDE-AI and other AI reporting guidelines can be useful to radiologists and researchers.

Abstract
BACKGROUND Deep sternal wound infection (DSWI) is a rare but severe complication after cardiac surgical procedures and has been associated with increased early morbidity and mortality. Studies reporting long-term outcomes in patients with DSWI have shown contradictory results. We performed a study-level meta-analysis evaluating the impact of DSWI on short- and long-term clinical outcomes. METHODS A systematic literature search was conducted to identify studies comparing short- and long-term outcomes of patients submitted to cardiac surgical procedures who developed DSWI and patients who did not. The primary outcome was overall mortality. Secondary outcomes were in-hospital mortality, follow-up mortality, major adverse cardiovascular events, myocardial infarction, and repeat revascularization. Postoperative outcomes were also investigated. RESULTS Twenty-four studies totaling 407 829 patients were included. Overall, 6437 (1.6%) patients developed DSWI. Mean follow-up was 3.5 years. DSWI was associated with higher overall mortality (incidence rate ratio [IRR], 1.99; 95% CI, 1.66-2.38; P < .001), in-hospital mortality (odds ratio, 3.30; 95% CI, 1.88-5.81; P < .001), follow-up mortality (IRR, 2.02; 95% CI, 1.39-2.94; P = .001), and major adverse cardiovascular events (IRR, 2.04; 95% CI, 1.60-2.59; P < .001). No differences in myocardial infarction and repeat revascularization were found, but limited studies reported those outcomes. DSWI was associated with longer postoperative hospitalization, stroke, myocardial infarction, and respiratory and renal failure. Sensitivity analyses on isolated coronary artery bypass grafting studies and by adjustment method were consistent with the main analysis. CONCLUSIONS Compared with patients who did not develop DSWI, patients with DSWI after cardiac surgical procedures had increased risk of death as well as short- and long-term adverse clinical outcomes.

Abstract
Since the initial shipment of vaccination campaign against SARS-CoV-2 infection, it was a major concern all over the world regarding appropriate gapping between the first and second dose and also the necessity of booster dose after being vaccinated with the second dose. This cross-sectional type of comparative study was conducted at Kuwait Bangladesh Friendship Government Hospital, from the period of March 01 2021 to August 31 2021, on 148 hospitalized patients who were vaccinated with Astra Zeneca. They were divided into two groups on the background of 1st dose and 2nd dose. Collected data were entered into SPSS-26 version and after data cleaning, descriptive analysis was done with frequency distribution. To find out the significant difference between the two groups considering clinico-demographic information, disease severity, and duration of the last dose of vaccine; the Pearson Chi-square test was done with a significance level ≤0.05. The patients from both groups were mostly male and above 60 years. There were no significant age or sex variations between the two groups. SARS-CoV-2 infection was common after 38 days of dose 1 and after 63 days of dose 2. Fever, cough, running nose, shortness of breath, fatigue, nausea, vomiting, lower oxygen saturation, radiological involvement were comparatively more in patients who got only a single dose. Mild pneumonia (70.7%) was the commonest presentation in both doses of vaccinated patients and single dose vaccinated patients mostly (45.5%) presented with severe pneumonia. Elderly clinically risks group patients were mostly hospitalized with infection after 1 month of the 1st dose and on the other hand after 2 months of completing the 2nd dose. Symptomatic infection and disease severity were more in 1st dose vaccine recipients in comparison to 2nd dose.

Abstract
OBJECTIVES The aim of this study was to perform a meta-analysis of studies reporting outcomes in patients with liver dysfunction addressed by the model of end-stage liver disease and Child-Turcotte-Pugh scores undergoing cardiac surgery. METHODS A systematic literature search was conducted to identify contemporary studies reporting short- and long-term outcomes in patients with liver dysfunction compared to patients with no or mild liver dysfunction undergoing cardiac surgery (stratified in high and low score group based on the study cut-offs). Primary outcome was perioperative mortality. Secondary outcomes were perioperative neurological events, prolonged ventilation, sepsis, bleeding and/or need for transfusion, acute kidney injury and long-term mortality. RESULTS A total of 33 studies with 48 891 patients were included. Compared with the low score group, being in the high score group was associated with significantly higher risk of perioperative mortality [odds ratio (OR) 3.72, 95% confidence interval (CI) 2.75-5.03, P < 0.001]. High score group was also associated with a significantly higher rate of perioperative neurological events (OR 1.49, 95% CI 1.30-1.71, P < 0.001), prolonged ventilation (OR 2.45, 95% CI 1.94-3.09, P < 0.001), sepsis (OR 3.88, 95% CI 2.07-7.26, P < 0.001), bleeding and/or need for transfusion (OR 1.95, 95% CI 1.43-2.64, P < 0.001), acute kidney injury (OR 3.84, 95% CI 2.12-6.98, P < 0.001) and long-term mortality (incidence risk ratio 1.29, 95% CI 1.14-1.46, P < 0.001). CONCLUSIONS The analysis suggests that liver dysfunction in patients undergoing cardiac surgery is independently associated with higher risk of short and long-term mortality and also with an increased occurrence of various perioperative adverse events.

Abstract
Abdominal surgery carries with it risks of complications. Little is known about patients' experiences of post-surgical deterioration. There is a real need to understand the psychosocial as well as the biological aspects of deterioration in order to improve care and outcomes for patients. Drawing on in-depth interviews with seven abdominal surgery survivors, we present an idiographic account of participants' experiences, situating their contribution to safety within their personal lived experiences and meaning-making of these episodes of deterioration. Our analysis reveals an overarching group experiential theme of vulnerability in relation to participants' experiences of complications after abdominal surgery. This encapsulates the uncertainty of the situation all the participants found themselves in, and the nature and seriousness of their health conditions. The extent of participants' vulnerability is revealed by detailing how they made sense of their experience, how they negotiated feelings of (un)safety drawing on their relationships with family and staff and the legacy of feelings they were left with when their expectations of care (care as imagined) did not meet the reality of their experiences (care as received). The participants' experiences highlight the power imbalance between patients and professionals in terms of whose knowledge counts within the hospital context. The study reveals the potential for epistemic injustice to arise when patients' concerns are ignored or dismissed. Our data has implications for designing strategies to enable escalation of care, both in terms of supporting staff to deliver compassionate care, and in strengthening patient and family involvement in rescue processes.

Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) has become the preferred treatment of abdominal aortic aneurysms (AAAs). Recent studies have demonstrated that cases of EVAR failure repair and subsequent open conversion have increased. The aim of the present study was to evaluate the national trend of annual cases and assess the 30-day outcomes of conversion to open repair after failed EVAR compared with primary open repair. METHODS The National Surgical Quality Improvement Program database was queried for relevant Current Procedural Terminology and International Classification of Diseases, Ninth and Tenth Revision, codes to identify patients who had undergone conversion to open repair or primary open repair of nonruptured AAAs from 2009 to 2018. The annual trend of cases was assessed, and the perioperative outcomes of both procedures were compared. Multivariable logistic regression analyses were conducted to identify independent perioperative factors associated with mortality. RESULTS Of the 9635 patients with nonruptured AAAs included in the present analysis, 9250 had undergone primary repair and 385 had required open conversion. During the 10-year period, the annual number of cases of open conversion had steadily increased and that of primary repair had decreased. The incidence of postoperative complications was similar between both groups, except for cardiac arrest, which had occurred more frequently in the open conversion group. The 30-day mortality was higher in the open conversion group than in the primary group (9.6% vs 3.9%; P < .0001). Open conversion was also independently associated with higher odds of death (adjusted odds ratio [OR], 2.1; 95% confidence interval [CI], 1.8-2.4; P < .0001). When the average mortality in both groups was compared between the first and last 5 years, no difference was found (open conversion: 9.8% vs 9.5% [P = 1.00]; primary repair: 3.6% vs 4.2% [P = .19]). Other perioperative factors independently associated with mortality included increased age (OR, 1.8; 95% CI, 1.5-2.1; P < .0001), American Society of Anesthesiologists class ≥III (OR, 2.7; 95% CI, 1.1-6.6; P = .029), insulin-dependent diabetes (OR, 2.0; 95% CI, 1.2-3.3; P = .005), chronic obstructive pulmonary disease (OR, 1.4; 95% CI, 1.1-1.8; P = .006), the presence of dyspnea at rest (OR, 3.3; 95% CI, 1.8-6.1; P < .0001), and a high preoperative hematocrit (OR, 0.94; 95% CI, 0.93-0.97; P < .0001). CONCLUSIONS Open conversion to treat nonruptured AAAs after failed EVAR was independently associated with higher mortality. Also, the annual cases of open conversion have continued to increase without any significant changes in postoperative mortality. This highlights the danger of open conversion and stresses the need for better solutions to prevent and manage EVAR failure.

Abstract
Randomized controlled trials (RCTs) in surgery face methodological challenges, which often result in low quality or failed trials. The Idea, Development, Exploration, Assessment and Long-term (IDEAL) framework proposes preliminary prospective collaborative cohort studies with specific properties (IDEAL 2b studies) to increase the quality and feasibility of surgical RCTs. Little empirical evidence exists for this proposition, and specifically designed 2b studies are currently uncommon. Prospective collaborative cohort studies are, however, relatively common, and might provide similar benefits. We will, therefore, assess the association between prior ‘IDEAL 2b-like’ cohort studies and the quality and impact of surgical RCTs.We propose a systematic review using two parallel case–control analyses, with surgical RCTs as subjects and study quality and journal impact factor (IF) as the outcomes of interest. We will search for surgical RCTs published between 2015 and 2019 and and prior prospective collaborative cohort studies authored by any of the RCT investigators. RCTs will be categorized into cases or controls by (1) journal (IF ≥or <5) and (2) study quality (PEDro score ≥or < 7). The case/control OR of exposure to a prior ‘2b like’ study will be calculated independently for quality and impact. Cases will be matched 1: 1 with controls by year of publication, and confounding by peer-reviewed funding, author academic affiliation and trial protocol registration will be examined using multiple logistic regression analysis.This study will examine whether preparatory IDEAL 2b-like studies are associated with higher quality and impact of subsequent RCTs.

Abstract
Abstract
Background
The Rapid Access Frailty assessment unit (RAFAU) was set up in February 2021 and is run by a Raft (Rapid access frailty team). This is a dedicated multidisciplinary team in a model three hospital to review frail older patients to improve outcomes and admission avoidance. They review patients in the Emergency department as well as the assessment unit and on the ward for inpatient frailty reviews. The team is expanding as new roles are incorporated into the team and our service has evolved into a five day a week rapid access service.
Methods
We examined the number of GP referrals to our RAFU since May 2021 to March 2022 and the outcome of the review. Data was collected on all patients attending the RAFAU over an 11-month period. We selected all GP referrals which produced a cohort of 259 referrals to the unit.
Results
A total of 259 referrals were reviewed in RAFAU clinics. Mean age was 70-75 years old 60% were female, 40 % male. Reason for referral included: 38 % medical reasons, 32% cognitive issues, 18 % mobility ,7 % falls. Overall, 41% of referred patients had Clinical frailty scale score of 1-3, 16 % had a clinical frailty scale of 4, 8% clinical frailty scale of 5, 9% clinical frailty scale of 6, 5% clinical frailty scale of 7.The outcome of this cohort were as follows: 86 % needed further follow up, 9% were discharged and 1% admitted.
Conclusion
The RAFAU gives an alternative referral destination to GP’s for rapid review of frail older patients and thus potentially avoiding ED referral and admission. The vast majority of these referrals were for review of medical issues and cognitive assessment. The majority of patients required ongoing specialist frailty services and we hope to expand our service in the future.

Abstract
Abstract
Background
Atrial fibrillation (AF) hospital admissions represent significant AF related treatment costs nationally. In the year 2019–2020 our hospital reported 1,333 admissions with a primary diagnosis of AF, with a 10% annual increase. A virtual ambulatory AF ward providing multidisciplinary care with remote hospital-level monitoring could reshape the future model of AF management.
Methods
An AF virtual ward was implemented at our UK tertiary centre, as a proof-of-concept model of care. Patients admitted with a primary diagnosis of AF satisfying the AF virtual ward (AFVW) entry criteria (i.e., haemodynamically stable, HR <140 bpm with other acute conditions excluded) were given access to a single lead ECG recording device, a Bluetooth integrated blood pressure machine and pulse oximeter with instruction to record daily ECGs, blood pressure readings, oxygen saturations and fill an online AF symptom questionnaire via a smart phone or electronic tablet. Data were uploaded to an integrated digital platform for review by the clinical team who undertook twice daily virtual ward rounds. Medication adjustment was arranged through the hospital pharmacy. Data was collected prospectively for patients admitted to the AF virtual ward between 31 January and 11 March 2022. Outcomes included length of hospital stay, admission avoidance and re-admissions. Re-admission avoidance was assessed using the index admission criteria as a parameter for re-admission likelihood. Patients' satisfaction was assessed using the NHS family and friends' test (FFT).
Results
Over the 6-week period a total of 14 patients were enrolled. One patient was unable to be onboarded because of technology related anxiety with 13 patients onboarded to the virtual ward, 30.7% (n=4) did not have smart phones and were provided with electronic tablets. The age on admission was 64±10 years (mean±SD) with the oldest at 78 years of age. All patients were in AF with a mean heart rate of 122±24 bpm, and 38.5% (n=5) were discharged from the virtual ward in sinus rhythm. One patient was onboarded directly from pacemaker clinic and hence hospital admission was completely avoided, and 5 re-admissions were avoided for 3 patients. One patient required brief readmission due to persistent tachycardia requiring acute cardioversion. The FFT yielded 100% positive responses among patients.
Conclusion
This proof-of-concept is a first real world experience of a virtual ward for hospital patients with fast AF. It demonstrates a promising new telemedicine-based care model and with clear appetite among both patients and health professionals. This model of care has the potential to reduce the financial and backlog pressures caused by AF admissions without compromising patients' care or safety. Work is ongoing to further confirm the safety and cost-effectiveness upon further progress in a larger patient cohort.

Abstract
BACKGROUND AND PURPOSE 3D intracranial vessel wall MRI techniques are time consuming and prone to artifacts, especially flow artifacts. Our aim was to compare the image quality of accelerated and flow-suppressed 3D intracranial vessel wall MR imaging techniques relative to conventional acquisitions. MATERIALS AND METHODS Consecutive patients undergoing MR imaging had conventional postcontrast 3D T1-sampling perfection with application-optimized contrasts by using different flip angle evolution (SPACE) and either postcontrast delay alternating with nutation for tailored excitation (DANTE) flow-suppressed or DANTE-controlled aliasing in parallel imaging results in higher acceleration (CAIPI) flow-suppressed and accelerated T1-SPACE sequences performed. The sequences were evaluated using 4- or 5-point Likert scales for overall image quality, SNR, extent/severity of artifacts, motion, blood suppression, sharpness, and lesion assessment. Quantitative assessment of lumen and wall-to-lumen contrast ratios was performed. RESULTS Eighty-nine patients were included. T1-DANTE-SPACE had significantly better qualitative ratings relative to T1-SPACE for image quality, SNR, artifact impact, arterial and venous suppression, and lesion assessment (P < .001 for each, respectively), with the exception of motion (P = .16). T1-DANTE-CAIPI-SPACE had significantly better image quality, lesion assessment, arterial and venous blood suppression, less artifact impact, and less motion compared with T1-SPACE (P < .001 for each, respectively). The SNR was higher with T1-SPACE compared with T1-DANTE-CAIPI-SPACE (P < .001). T1-DANTE-CAIPI-SPACE showed significantly worse lumen (P = .005) and wall-to-lumen contrast ratios (P = .001) compared with T1-SPACE, without a significant difference between T1-SPACE and T1-DANTE-SPACE. T1-DANTE-CAIPI-SPACE scan time was 5:11 minutes compared with 8:08 and 8:41 minutes for conventional T1-SPACE and T1-DANTE-SPACE, respectively. CONCLUSIONS Accelerated postcontrast T1-DANTE-CAIPI-SPACE had fewer image artifacts, less motion, improved blood suppression, and a shorter scan time, but lower qualitative and quantitative SNR ratings relative to conventional T1-SPACE intracranial vessel wall MR imaging. Postcontrast T1-DANTE-SPACE had superior SNR, blood suppression, higher image quality, and fewer image artifacts, but slightly longer scan times relative to T1-SPACE.

Introduction
Chronic right ventricular apical pacing can lead to pacing induced cardiomyopathy in a significant proportion of patients. Conduction system pacing may restore more physiological activation of the heart, and has recently been shown to have favourable outcomes in clinical trials. However there remains concern regarding the long-term outcomes due to lead displacement and high pacing thresholds. The most widely used technique in current practice is to pace the His bundle proximal to the tricuspid valve. Distal His bundle pacing has a number of advantages over proximal His pacing, including, lower capture thresholds, a more stable lead position, less far field atrial sensing and better spacing from the AV node in case ablation of this is required for AF rate control. Despite these, outcomes of distal His bundle pacing from the ventricular aspect are less well defined.
Methods
We performed a retrospective review of patients who underwent conduction system pacing between January 2020 and October 2021 at our centre. During this period all procedures were performed employing a distal His bundle pacing approach with the lead placed on the ventricular aspect of the tricuspid annulus. Data was collected at implant, follow-up at 1 month and then every 6 months.
Results
Out of 35 patients, 33 underwent successful His bundle pacing (acute success rate of 94%), 1 patient had left bundle branch pacing and another patient had an unsuccessful procedure. Mean age was 74 years, median LVEF 45% and median pre-implant QRS was 108ms. 80% of the cohort had a history of AF. The indications for pacing were as follows: AF - for pace & ablate (60%); high grade AV block with narrow QRS and mild LVSD (17%); failed LV lead (14%); and other 9%. Mean procedure duration and fluoroscopy time were 78 minutes and 12.05 minutes, respectively. Median threshold at implant was 1.00V (IQR 0.719V). Selective His bundle pacing was achieved in 60% and non-selective in 34%. Mean follow-up duration was 150 days with median threshold at last f/up of 0.75V (IQR 0.750V). There were no acute procedural complications. 1 patient had a significant rise in threshold at follow-up and therefore required upgrade to CRT-P.
Discussion
Our data shows that distal His bundle pacing is a safe and effective technique for conduction system pacing. Thresholds appear stable at follow-up and failure rate was found to be comparable to biventricular pacing. We noted an initial learning curve for both implanter and physiologists with relatively poorer outcomes for the earlier cases. Longer term follow-up is ongoing, including functional assessment and follow-up to assess for remodelling with echocardiography. Prospective randomised trials are needed to compare conduction system pacing vs RV pacing in AF patients with HFpEF or mild LVSD undergoing AVN ablation, and vs biventricular pacing in the severe LVSD population.

Introduction
Many patients with atrial fibrillation (AF) do not benefit from rhythm control due to failed catheter ablation, advanced left atrial disease and comorbidities. "Pace and AV node (AVN) ablation" strategy is often adopted for rate control but with a substantial risk of pacing-induced cardiomyopathy. His bundle pacing (HBP) enables physiological biventricular activation through the His Purkinje conduction system. However, the proximity of the HBP lead to the site of AV node ablation may potentially compromise lead integrity in patients who undergo conventional HBP and AVN ablation. Therefore, we have modified HBP by placing the HBP lead distally at the ventricular side of the His bundle (D-HBP) before AVN ablation in patients with symptomatic AF. All patients had a backup RV lead.
Method
Patients who had D-HBP as part of a "Pace and AVN ablation" strategy were retrospectively analysed. Implant and device clinic follow-up data were collected and analysed.
Result
Twenty-one patients who had "pace and AVN ablation strategy" with D-HBP between 26th February 2020 and 3rd November 2021 were included. They had a mean age of 75 ± 1.4 years (mean ± SEM), NYHA class of 2.1 ± 0.2, QRS duration of 106 ± 5.3ms and 50% had at least moderately impaired LV systolic function. Seventeen patients (81%) had narrow QRS duration. D-HBP was successful in twenty of twenty-one patients (95%). At D-HBP implant, the mean acute threshold of the HBP lead was 0.96 ± 0.12V at 0.5 ± 0.05ms and the mean HBP lead impedance was 548.1 ± 29.5Ω. Selective HBP pacing was observed in thirteen of twenty patients. The mean QRS duration of HBP paced beats was 104.5 ± 4.7ms. Failure to capture the His bundle was observed in one patient. AVN ablation was performed on the same day after D-HBP in eleven patients and as a subsequent procedure in nine patients. The mean duration of procedure and fluoroscopy for D-HBP were 77.4 ± 4.6 minutes and 11.9 ± 1.4 minutes respectively. There were no acute procedural complications with no lead damage, displacement or lead perforation observed. The median follow-up period was 207 days. The mean D-HBP lead threshold following AVN ablation was 1.1 ± 0.2 V at 0.6 ± 0.07 ms and the mean lead impedance was 433.8 ± 20.7Ω, which were similar to before AVN ablation. One patient was reprogrammed with RV pacing only for elevated HBP lead threshold after AVN ablation to 4.2 V at 1ms. The mean D-HBP percentage was 92.3 ± 6.6% and the mean estimated battery longevity of the pacemaker was 7.9 ± 0.6 years at the last follow up. There was improvement in heart failure symptoms in eight patients from previously symptomatic to NYHA class I following D-HBP and AVN ablation.
Conclusion
D-HBP appear to be safe with potentially more favourable lead parameters than conventional proximal HBP in patients with symptomatic AF offered "Pace and AVN ablation" strategy.

Abstract
OBJECTIVE To investigate the effects of some potential risk factors on early pregnancy loss -EPL - in a cohort of pregnant women treated by assisted reproductive technology - ART. METHODS This is a retrospective cohort of 195 pregnancies, defined as serum human chorionic gonadotrophins ≥ 10 IU/l on day 14 - 17 after embryo transfer, recruited from an assisted reproductive technology unit, Ain Shams & Al-Azhar Maternity hospital, Cairo, Egypt, during the period from January 1st, 2016 to December 31, 2020. Risk factors investigated were maternal age, body mass index, status, baseline hormonal profiles, treatment protocol, quality and number of embryos. RESULTS Overall early pregnancy loss among the studied 195 pregnant women was 29 cases (15%). The risk of early pregnancy loss was associated with older age and fewer number of embryos transferred. Women > 35 years were found to have two and half times of early pregnancy loss compared with younger age group < 25 years, this was not significant after adjusting for other factors. The risk in both lean (BMI < 25 kg/m2) and very obese (BMI > 35 kg/m2) women was also not significantly higher in unadjusted analysis. Transfer of two or more embryos was associated with a non-significant reduced risk of early pregnancy loss, and after adjusting for other factors, the reduction was about 70%. CONCLUSIONS Early pregnancy loss represents a considerable drawback of intracytoplasmic sperm injection treated women with old age to increase the risk of early pregnancy loss and transferring more than one embryo to reduce the risk by about 70%. Obesity and other factors appeared to play a minor role.

Abstract
There is no consensus on the best treatment modality for acute distal embolization complications during endovascular interventions for peripheral arterial diseases. We report on 3 patients who underwent mechanical embolectomy using a distal embolic protection device (EPD). All patients showed angiographic evidence of distal embolism, which occurred during lower extremity limb salvage endovascular procedures. After embolectomy, all had complete recanalization of the involved vessel on completion angiogram, and none had any device-related complications or adverse outcomes from the embolization. This initial experience suggests that EPD can be used for both the prevention and treatment of intraoperative distal embolization during endovascular intervention of lower extremity arterial disease.

Abstract
A growing number of artificial intelligence (AI)-based clinical decision support systems are showing promising performance in preclinical, in silico evaluation, but few have yet demonstrated real benefit to patient care. Early-stage clinical evaluation is important to assess an AI system's actual clinical performance at small scale, ensure its safety, evaluate the human factors surrounding its use and pave the way to further large-scale trials. However, the reporting of these early studies remains inadequate. The present statement provides a multi-stakeholder, consensus-based reporting guideline for the Developmental and Exploratory Clinical Investigations of DEcision support systems driven by Artificial Intelligence (DECIDE-AI). We conducted a two-round, modified Delphi process to collect and analyze expert opinion on the reporting of early clinical evaluation of AI systems. Experts were recruited from 20 pre-defined stakeholder categories. The final composition and wording of the guideline was determined at a virtual consensus meeting. The checklist and the Explanation & Elaboration (E&E) sections were refined based on feedback from a qualitative evaluation process. In total, 123 experts participated in the first round of Delphi, 138 in the second round, 16 in the consensus meeting and 16 in the qualitative evaluation. The DECIDE-AI reporting guideline comprises 17 AI-specific reporting items (made of 28 subitems) and ten generic reporting items, with an E&E paragraph provided for each. Through consultation and consensus with a range of stakeholders, we developed a guideline comprising key items that should be reported in early-stage clinical studies of AI-based decision support systems in healthcare. By providing an actionable checklist of minimal reporting items, the DECIDE-AI guideline will facilitate the appraisal of these studies and replicability of their findings.

Abstract
BACKGROUND Metabolic syndrome contributes to the burden of non-communicable diseases and is a growing public health problem in both developed and developing countries. We determined the prevalence and predictors of metabolic syndrome among adults in Benue State, North-Central, Nigeria to guide targeted interventions. METHODS We conducted a community-based cross-sectional study in Benue State, North-Central, Nigeria. Multistage sampling technique was used to recruit 823 respondents. We defined metabolic syndrome using the National Cholesterol Education Programme Adult Treatment Panel III guideline and adapted a component of the WHO Stepwise questionnaire for data collection. Prevalence of metabolic syndrome and the associated risk factors were estimated using Chi square test and logistic regression at 5% level of significance. Statistical analysis was done using SPSS version 23.0. RESULTS The mean age of the respondents was 40.1± 15.7 years. Most of the respondents were literate (86.8%) and married (67.0%). The prevalence of metabolic syndrome was 19.4%. One in every four of the respondents had pre-metabolic syndrome (25.6%) and this was more in females (28.2%) compared to males (22.9%). Thirty-four percent of the respondents had only one whereas 20.7% did not have any of the risk factors for metabolic syndrome. Age [aOR:10.3; 95%CI: 4.8-22.2], sex [aOR:2.4; 95% CI: 1.7-3.5] and education [aOR:2.9; 95%CI: 1.4-6.1] were significantly associated with metabolic syndrome among the respondents. CONCLUSION The prevalence of metabolic syndrome was high. The associated risk factors were age, gender and educational status. Therefore, interventions should be targeted at young adults to reduce the long-term impact of the disease.

Abstract
Background Somalia has been without an effective government since the collapse of the military regime in 1991. Years of conflict, disasters, and insecurity have all contributed to very low scores for most health indicators due to poor governance, protracted conflict, underdevelopment, economic decline, poverty, social and gender inequality, and environmental degradation. The three-decade long protracted conflict has led to widespread psychosocial trauma, social deprivation and substance abuse with devastating consequences on mental health. A WHO study showed Somalia has one of the highest rates of mental illness in the world. The main aim of this study is to assist policy makers in setting priorities for the design and delivery of interventions to promote mental health and psychosocial wellbeing in Somalia. Methods The study uses a systematic mapping technique (from January 1991 to May 2020) and data collected from public domain, to collect, collate, and present mental health data mainly from WHO’s Global Health Observatory. Since there is no primary database for Somalia’s public health research, the bibliographic databases used for mental health in this study included Medline, PubMed, CINAHL, PsycINFO, and Google Scholar. Data were extracted using techniques for web data mining for public health. Results Systematic mapping of mental health-related issues in Somalia showed that policy-related determinants and mental health services dominated (74.4%), followed by the disaster-related determinants and women’s health consequences (39.3%). The ratio of the number of beds for mental health in general hospitals (per 100,000 population) in Somalia in 2017 is 0.5 compared to the Eastern Mediterranean region (EMR) at 6.4 and globally at 24. One of the biggest casualties of the civil war was loss of essential human resources in healthcare as most either fled the country or were part of the victims of the war. Conclusions The vast scale of the mental health problems in Somalia and the priority setting guidelines for interventions to address the issues outlined in this paper, prompt a dire need that the Somali government and its national/international partners should prioritize and emphasize the need to invest in the prevention and the treatment of mental illness across the country.

Abstract
BACKGROUND Failure to rescue (FTR) denotes mortality from post-operative complications after surgery with curative intent. High-volume, low-mortality units have similar complication rates to others, but have lower FTR rates. Effective response to the deteriorating post-operative patient is therefore critical to reducing surgical mortality. Resilience Engineering might afford a useful perspective for studying how the management of deterioration usually succeeds and how resilience can be strengthened. METHODS We studied the response to the deteriorating patient following emergency abdominal surgery in a large surgical emergency unit, using the Functional Resonance Analysis Method (FRAM). FRAM focuses on the conflicts and trade-offs inherent in the process of response, and how staff adapt to them, rather than on identifying and eliminating error. 31 semi-structured interviews and two workshops were used to construct a model of the response system from which conclusions could be drawn about possible ways to strengthen system resilience. RESULTS The model identified 23 functions, grouped into five clusters, and their respective variability. The FRAM analysis highlighted trade-offs and conflicts which affected decisions over timing, as well as strategies used by staff to cope with these underlying tensions. Suggestions for improving system resilience centred on improving team communication, organisational learning and relationships, rather than identifying and fixing specific system faults. CONCLUSION FRAM can be used for analysing surgical work systems in order to identify recommendations focused on strengthening organisational resilience. Its potential value should be explored by empirical evaluation of its use in systems improvement.

Abstract
The study was undertaken from September 2018 to April 2019 to determine the prevalence of cutaneous leishmaniasis in human beings living in six districts of Karachi. Suspected persons were screened for the disease and positive cases were identified on the basis of skin lesions and blood samples. Samples were observed by mounting their smear. A total of 207 subjects of different ages and sex groups were investigated, however, only 192 (92%) of the suspected cases were found to have the disease 64% of cases were male which were significantly high (p 0.05), than female 36%. The lesion was more frequently detected among the youth ages of 21-30 years (31%) as compared to other groups. In both sexes, legs were found to be more infected (25% male + 20% female) followed by arms (20% male + 0% female) and face (15% male +11% female). The mixed body parts had shown the lowest infections such as (4% in males + 5%) in females. In conclusion, the highest and lowest leishmaniasis infections were observed in District West (23% male + 9% female) followed by District East (15% male + 7% female), District Malir (11% male+ 4% female), District Central (7% male + 5% female), District Korangi (4% male + 7% female) and District South (4% male + 4% female) respectively.

Abstract
Abstract
Background
Pulmonary arterial hypertension (PAH) is a frequent complication of congenital heart disease (CHD), notably in patients with left-to-right shunts. Patients with severe PAH due to CHD, Eisenmenger syndrome (ES), represent a high-risk group of pulmonary artery (PA) thrombosis patients. We present serial adult cases of CHD with PAH complicated by pulmonary embolism (PE).
Case Description
We found 3 cases of pulmonary embolism on adult congenital heart disease in our center. All of the patients were female, with an age range of 36 to 61 years old. The presenting symptoms were shortness of breath, WHO classification class II-III. All patients were hemodynamically stable. CHD and estimated RV systolic pressure were evaluated with echocardiography. CT-PA was performed in all patients, which findings were supporting PE. All patients were treated with anticoagulation. After three months, right heart catheterization was conducted in two patients, and one patient was refused.
Discussion
The prevalence of PE among adult patient with CHD and PAH range from 17 to 21%. PE was frequently found in older patients, women, and patients with lower oxygen saturation. To date, no uniformity regarding routine prophylaxis anticoagulation therapy in ES due to the high bleeding risk in this population despite being at risk of PA thrombosis. We conclude that risk stratification for PA thrombosis in adult CHD-PAH patients is essential, and further research is needed to prevent PE in this population.

Abstract
The present study was aimed to manifest the antibacterial and antifungal activity of methanolic extracts of Salix alba L. against seven Gram-positive and Gram-negative bacterial pathogens e.g. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) and Neisseria gonorrhoeae and three fungal isolates from the air such as Aspergillus terreus, A. ornatus, and Rhizopus stolonifer. Two different serotypes of S. aureus and E. coli were used. The agar well-diffusion method results showed the dose-dependent response of plant extracts against bacterial and fungal strains while some organisms were found resistant e.g. E. coli (1), S. sonnei, A. terreus and R. stolonifer. The highest antibacterial activity was recorded at 17.000±1.732 mm from 100 mg/mL of leaves methanolic extracts against S. pyogenes while the activity of most of the pathogens decreased after 24 h of incubation. The highest antifungal activity was reported at 11.833±1.0 mm against A. ornatus at 50 mg/mL after 48 h of the incubation period. These experimental findings endorse the use of S. alba in ethnopharmacological formulations and suggest the use of methanolic extracts of the said plant to develop drugs to control the proliferation of resistant disease causing pathogenic microbes.

Abstract
AIM Forklift trucks can cause serious lower limb trauma with long-lasting sequelae to patients. The aim of this study was to analyse a case series of patients with forklift-related injuries over 7 years at a level 1 major trauma centre in the UK and present their patient-reported outcome measures (PROMs) with long-term follow-up. To the best of the authors' knowledge, this is the largest case series study in the UK describing forklift injuries. METHODS Retrospective case note analysis of 19 patients over 7 years. Data including demographics, injury mechanism, pattern of injury, management, length of hospital stay, number of operations and complications were extracted from the notes. We used 'Enneking score' as a validated tool for PROMs. RESULTS Seventeen men and two women with mean age of 47 years; 20% had bilateral injuries and 34% had multi-level fractures. The mean number of theatre sessions was 5.21, while the mean length of hospital stay was 30.10 days. There was one mortality. Twelve patients (63%) required reconstruction with free tissue transfer, with one flap failure. The mean long-term Enneking percentage score was 57.33%. The mean Enneking score for patients in this study is lower than our institute's score for Gustilo 3B, highlighting the gravity of these injuries. CONCLUSION Forklifts can cause grave injuries with massive energy transfer. This study highlights the seriousness of those injuries, thus guiding patient counselling and optimising planning of management.

Abstract
BACKGROUND Refractory septic shock in neonates is still associated with high mortality, necessitating an alternative therapy, despite all currently available treatments. This study aims to assess the vasopressor effect of methylene blue (MB) in comparison to terlipressin (TP) as adjuvant therapy for refractory septic shock in the preterm neonate. METHODS A double-blinded randomized controlled trial was conducted in the Neonatal Intensive Care Units at Ain Shams University, Egypt. Thirty preterm neonates with refractory septic shock were randomized to receive either MB or TP as an adjuvant to conventional therapy. Both MB and TP were administered as an intravenous loading dose followed by continuous intravenous infusion. The hemodynamic variables, functional echocardiographic variables, and oxidant stress marker were assessed over a 24 h period together with the side effects of MB. RESULTS MB causes significant improvement in mean arterial blood pressure with a significant decrease of the norepinephrine requirements (1.15±0.21μm/kg/min at baseline vs. 0.55±0.15μm/kg/min at 24 h). MB infusion causes an increase of the pulmonary pressure (44.73±8.53 mmHg at baseline vs. 47.27±7.91 mmHg after 24 h) without affecting the cardiac output. Serum malonaldehyde decreased from 5.45±1.30 nmol/mL at baseline to 4.40±0.90 nmol/mL at 24 h in the MB group. CONCLUSION Administration of MB to preterm infants with refractory septic shock showed rapid increases in systemic vascular resistance and arterial blood pressure with minimal side effects.

Abstract
Abstract
Aim
to Assess the feasibility and safety of selective non-operative management in penetrating abdominal injuries and to identify a protocol for selection of patient’s candidates for non-operative management.
Method
In this comparative study 40 abdominal stab victims (admitted to Emergency Department of Alexandria Main University Hospital) were selected during 6 months period where 20 patients were suitable for non-operative management according to strict selection criteria whereas the other 20 patients were operated according to clinical and/or radiological indications or on basis of department protocol, the results were compared in view of final outcome.
Results
In our study, 15 patients were assigned for operative management according to selected clinical and/or radiological indications only 3 of them (20%) had non-therapeutic laparotomies, On the other hand, five patients were explored on basis of department protocol in violation of our indications for exploration; four of them (80%) were non-therapeutic. So, the rate of non-therapeutic laparotomies was significantly higher when done mandatory without selected clinical and radiological indications.
Conclusions
Assessment of vital signs together with abdominal examination are the most important and dependable tools in decision making in penetrating abdominal trauma patients. Patients with shock on admission (but responding to resuscitation), proved low grade solid organ injury (by CT), and proved intraperitoneal collection (by US or CT) could be managed conservatively regarding that they remain vitally and clinically stable. If failure of conservation occurs, it is usually during the 1st 24 hours after admission.
