Abstract
BACKGROUND Pancreatitis is a common surgical emergency, associated with pain and poor quality of life for patients. However, assessment of patient-reported outcome measures in these patients is unclear. This study aimed to identify and evaluate the methodological quality of the health-related quality of life instruments used for patients with acute or chronic pancreatitis. METHODS Prospective studies that evaluated health-related quality of life in acute or chronic pancreatitis were identified from systematic review of MEDLINE, EMBASE, and Web of Science until 28th June 2023 (PROSPERO: CRD42021274743). Instrument characteristics were extracted, and methodological quality assessed using COSMIN (COnsensus-based Standards for the selection of health status Measurement Instruments) guidelines and GRADE approach. Narrative synthesis was conducted, with recommendations for use based on COSMIN criteria, evaluated according to World Health Organisation (WHO) quality of life domains. RESULTS From 3850 records screened, 41 quality of life instruments were identified across 138 studies included. The majority (69.8%, n = 26) were designed to assess general health-related quality of life, whereas the remainder were abdominal-specific (n = 5) or pancreas-specific (n = 10). Only ten instruments (24.3%) demonstrated sufficient content validity, incorporating items in ≥5 WHO quality of life domains. However, only nine instruments (21.9%) incorporated public and patient involvement. Only the Gastrointestinal Quality of Life Index and PAN-PROMISE met the criteria to be recommended for use based on COSMIN methodological assessment. CONCLUSION There is significant heterogeneity in instruments used to assess quality of life after pancreatitis, with almost all instruments considered insufficient. Robust, validated, and relevant instruments are needed to better understand and determine appropriate interventions to improve quality of life for these patients.

Abstract
Background Enhanced recovery after surgery (ERAS) protocols have largely been incorporated into practice in high-income settings due to proven improvement in perioperative outcomes. We aimed to review the implementation of ERAS protocols and other perioperative optimisation strategies in low- and middle-income countries (LMICs) and their impact on length of hospital stay (LOS). Methods We searched MEDLINE, PubMed, Global Health (CABI), WHO Global Index Medicus, Index Medicus, and Latin American and Caribbean Health Sciences Literature (LILACS) for studies incorporating ERAS or other prehabilitation approaches in LMICs. We conducted a pooled analysis of LOS using a random-effects model to evaluate the impact of such programs. This systematic review was pre-registered on PROSPERO. Results We screened 1205 studies and included 70 for a full-text review; six were eligible for inclusion and five for quantitative analysis, two of which were randomised controlled trials. ERAS was compared to routine practice in all included studies, while none implemented prehabilitation or other preoperative optimisation strategies. Pooled analysis of 290 patients showed reduced LOS in the ERAS group with a standardised mean difference of -2.18 (95% confidence interval (CI) = -4.13, -.0.05, P < 0.01). The prediction interval was wide (95% CI = -7.85, 3.48) with substantial heterogeneity (I2 = 94%). Conclusions Perioperative optimisation is feasible in LMICs and appears to reduce LOS, despite high levels of between-study heterogeneity. There is a need for high-quality data on perioperative practice in LMICs and supplementary qualitative analysis to further understand barriers to perioperative optimisation implementation.

Abstract
Medical students have an essential role in medical research, yet often lack opportunities for involvement within randomised trials. This study aimed to understand the educational impact of clinical trial recruitment for medical students. Tracking wound infection with smartphone technology (TWIST) was a randomised controlled trial that included adult patients undergoing emergency abdominal surgery across two university teaching hospitals. All recruiters underwent prerecruitment training based on 'Generating Student Recruiters for Randomised Trials' principles, and completed prerecruitment and postrecruitment surveys. Respondent agreement with statements were assessed using 5-point Likert scales (from 1 ('strongly disagree') to 5 ('strongly agree')). Quantitative data were analysed using paired t-tests to compare differences pre-involvement and post-involvement. Thematic content analysis was performed on free-text data to generate recommendations for future student research involvement. Of 492 patients recruited to TWIST between 26 July 2016 and 4 March 2020, 86.0% (n=423) were recruited by medical students. Following introduction of student co-investigators (n=31), the overall monthly recruitment rate tripled (4.8-15.7 patients). 96.8% of recruiters (n=30/31) completed both surveys, and all respondents reported significant improvement in clinical and academic competencies. Three higher-level thematic domains emerged from the qualitative analysis: (1) engagement, (2) preparation and (3) ongoing support. Student recruitment in clinical trials is feasible and accelerates recruitment to clinical trials. Students demonstrated novel clinical research competencies and increased their likelihood of future involvement. Adequate training, support and selection of suitable trials are essential for future student involvement in randomised trials.

Abstract
Abstract
Introduction
Malnutrition is a key priority on the global health agenda, yet the impact of nutritional state on cancer surgery across income strata remains poorly described. This study aimed to determine the effect of malnutrition on early postoperative outcomes following elective surgery for colorectal or gastric cancer.
Method
Multicentre, international prospective cohort study of consecutive patients undergoing elective surgery for colorectal or gastric cancer. Malnutrition was defined using the Global Leadership Initiative on Malnutrition (GLIM) criteria. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression and three-way mediation analysis determined the relationship between country income group, nutritional status and early postoperative outcomes.
Result
This study included 5709 patients (4593 colorectal; 1116 gastric) from 381 hospitals in 75 countries. Severe malnutrition was present in one third of patients, with a disproportionate burden in upper middle (44%) and low/lower-middle income countries (64%). After adjustment for patient and hospital risk factors, severe malnutrition (aOR 1.62, 95% confidence interval 1.07 to 2.48; P = 0.024) was an independent predictor of 30-day mortality. However, major postoperative complications and surgical site infection rates were similar.
Conclusion
Severe malnutrition represents a high global burden in cancer surgery, particularly within low-income settings. Malnutrition is an independent risk-factor for 30-day mortality following elective surgery for colorectal or gastric cancer, suggesting perioperative nutritional interventions may improve early outcomes following cancer surgery.
Take-home Message
Severe malnutrition affects a large proportion of elective surgical oncology patients, with a significantly higher burden in low and middle income countries. Severe malnutrition is independently associated with increased 30-day mortality after cancer surgery.

Abstract
BACKGROUND COVID-19 is a multisystem disease and patients who survive might have in-hospital complications. These complications are likely to have important short-term and long-term consequences for patients, health-care utilisation, health-care system preparedness, and society amidst the ongoing COVID-19 pandemic. Our aim was to characterise the extent and effect of COVID-19 complications, particularly in those who survive, using the International Severe Acute Respiratory and Emerging Infections Consortium WHO Clinical Characterisation Protocol UK. METHODS We did a prospective, multicentre cohort study in 302 UK health-care facilities. Adult patients aged 19 years or older, with confirmed or highly suspected SARS-CoV-2 infection leading to COVID-19 were included in the study. The primary outcome of this study was the incidence of in-hospital complications, defined as organ-specific diagnoses occurring alone or in addition to any hallmarks of COVID-19 illness. We used multilevel logistic regression and survival models to explore associations between these outcomes and in-hospital complications, age, and pre-existing comorbidities. FINDINGS Between Jan 17 and Aug 4, 2020, 80 388 patients were included in the study. Of the patients admitted to hospital for management of COVID-19, 49·7% (36 367 of 73 197) had at least one complication. The mean age of our cohort was 71·1 years (SD 18·7), with 56·0% (41 025 of 73 197) being male and 81·0% (59 289 of 73 197) having at least one comorbidity. Males and those aged older than 60 years were most likely to have a complication (aged ≥60 years: 54·5% [16 579 of 30 416] in males and 48·2% [11 707 of 24 288] in females; aged <60 years: 48·8% [5179 of 10 609] in males and 36·6% [2814 of 7689] in females). Renal (24·3%, 17 752 of 73 197), complex respiratory (18·4%, 13 486 of 73 197), and systemic (16·3%, 11 895 of 73 197) complications were the most frequent. Cardiovascular (12·3%, 8973 of 73 197), neurological (4·3%, 3115 of 73 197), and gastrointestinal or liver (0·8%, 7901 of 73 197) complications were also reported. INTERPRETATION Complications and worse functional outcomes in patients admitted to hospital with COVID-19 are high, even in young, previously healthy individuals. Acute complications are associated with reduced ability to self-care at discharge, with neurological complications being associated with the worst functional outcomes. COVID-19 complications are likely to cause a substantial strain on health and social care in the coming years. These data will help in the design and provision of services aimed at the post-hospitalisation care of patients with COVID-19.

Abstract
This work presents the applicability of applying a fuzzy logic approach to the calculation of noontime erythemal UV irradiance for the plain areas of Egypt. When different combinations of data sets were examined from the test performance point of view, it was found that 91% of the whole series was estimated within a deviation of less than +/-10 mW/m(2), and 9% of these deviations lay within the range of +/-15 mW/m(2) to +/-25 mW/m(2).

Abstract
ABSTRACT
The enzymatic cleavage of synthetic oxytocin and 8-lysine vasopressin by sera of women in advanced pregnancy was investigated by using paper chromatography. Following incubation of either hormone with pregnancy serum and subsequent oxidation, two molecular fractions were formed, of which one could be identified as L-cysteic acid. By contrast, oxidation of the intact cyclopeptide hormones did not lead to liberation of free L-cysteic acid. It was concluded that oxytocin and 8-lysine vasopressin were cleaved by an identical mechanism involving splitting of the peptide bond joining the tyrosine residue (position 2) to the amino-terminal halfcystine residue (position 1). Pregnancy serum »oxytocinase« and »vasopressinase« thus appeared to be one and the same enzyme.
