Introduction Surgical antimicrobial prophylaxis (SAP) means the administration of antibiotics in surgical practice, and it reduces the likelihood of surgical site infections (SSIs). Inappropriate SAP practice regarding the prescription, timing, and duration of antibiotic use prolongs the hospital stay of patients, increases patient morbidity (by exposing them to the adverse effects of antibiotics), promotes bacterial resistance, and puts an economic burden on health care. While developed countries regularly monitor and revise their SAP protocols, there are only a few such researches in developing countries, which is a major setback to proper surgical care. Objectives of the study This study aims to compare the practice of SAP in a tertiary health care hospital of a developing country Pakistan, with internationally recommended protocols and evaluate the impact of knowledge of international guidelines on SAP practice. The results of the study will highlight important shortcomings in prophylactic practice in the hospital and help develop recommendations to improve SAP practice and ensure better surgical care for patients.

Background There is conflicting literature pertaining to the risk factors of asymptomatic bacteriuria (ASBU) in diabetic women. ASBU is a well-established risk factor for frequent urinary tract infections (UTIs), and the risk factors that predispose diabetic women to ASBU should, therefore, be evaluated. Objectives This study aims to discern these aforesaid risk factors in type-2 diabetic women, define a population subset at particularly high risk for ASBU, and gauge the efficacy inherent in adhering to an antibiotic regimen in combatting ASBU. Methods An analytical, case-control study was conducted at the Diabetic Clinic of the Holy Family Hospital (HFH), Rawalpindi, Pakistan. The participants included were type-2 diabetic women reporting to the clinic for routine follow-up. Six hundred and sixty-seven urine samples from these type-2 diabetic women were evaluated. Positive cases were those in which patients were diagnosed with ASBU according to the guidelines, while those with no ASBU constituted the control group. Common risk factors for UTI were excluded in both groups. Age, socioeconomic status, hygiene practices, and contraceptive use were matched between cases and controls. Results Nineteen percent of type-2 diabetic women presented with ASBU in our study. The significant risk factors for ASBU were a higher HbA1c level (OR 1.97), more years since the initial diagnosis of diabetes (OR 1.49), a prior UTI history (OR 2.49), excessive antibiotic use (OR 2.72), sodium-glucose cotransporter-2 (SGLT2) inhibitor use (OR 1.75), and proteinuria (OR 1.88) in the multivariate model. Body mass index (BMI), age of the patients, pyuria, and voiding dysfunction manifested no association with ASBU. Antibiotic use was significantly associated with the type of bacterial species precipitating the ASBU. Conclusion The clinicians must keep in mind the association between the various patient parameters and ASBU, especially in prescribing antibiotics to diabetic women. More studies are needed to further elaborate on these risk factors and revise the patient management in at-risk cases for ASBU and UTIs.

Introduction Coronavirus disease 2019 (COVID-19) is the ongoing pandemic with multitude of manifestations and association of ABO blood group in South-East Asian population needs to be explored. Methods It was a retrospective study of patients with COVID-19. Blood group A, B, O, and AB were identified in every participant, irrespective of their RH type and allotted groups 1, 2,3, and 4, respectively. Correlation between blood group and lab parameters was presented as histogram distributed among the four groups. Multivariate regression and logistic regression were used for inferential statistics. Results The cohort included 1067 patients: 521 (48.8%) participants had blood group O as the prevalent blood type. Overall, 10.6% COVID-19-related mortality was observed at our center. Mortality was 13.9% in blood group A, 9.5% in group B, 10% in group C, and 10.2% in AB blood group (p = 0.412). IL-6 was elevated in blood group A (median [IQR]: 23.6 [17.5,43.8]), Procalcitonin in blood group B (median [IQR]: 0.54 [0.3,0.7]), D-dimers and CRP in group AB (median [IQR]: 21.5 [9,34]; 24 [9,49], respectively). Regarding severity of COVID-19 disease, no statistical difference was seen between the blood groups. Alteration of the acute phase reactants was not positively associated with any specific blood type. Conclusion In conclusion, this investigation did not show significant association of blood groups with severity and of COVID-19 disease and COVID-19-associated mortality.

Background and objective Urinary tract infections (UTIs) are usually treated with empirical therapy by physicians based on previous knowledge of the predictability of causative agents and their antimicrobial susceptibilities. The objective of this study was to determine the frequency of various pathogens causing UTIs and their antimicrobial resistance profile in patients presenting to the outpatient department (OPD) of a tertiary care hospital. Materials and methods This descriptive cross-sectional study was conducted in the urology OPD of a tertiary care hospital in Pakistan. The study was conducted over a period of six months, and it included 1,000 patients (of ages 12 years or above) who were clinically suspected for UTIs. Patients with comorbidities and immunocompromised patients were excluded from the study. Recipients of corticosteroid therapy or those with a history of intake of broad-spectrum antibiotics in the previous 15 days were also excluded. The modified Kirby-Bauer disc diffusion method was used for determining antimicrobial resistance against various antimicrobials. Results Out of 1,000 tested specimens, 530 (53%) isolates were found to be culture-positive. E.coli was the most common species isolated from the cultures with a prevalence of 77.4%, followed by Klebsiella (6.4%), Enterobacter (6.0%), Pseudomonas (3.8%), Staphylococcus saprophyticus (3.4%), Citrobacter (1.1%), and Morganella (0.4%). Antimicrobial resistance against commonly used antimicrobials was found to be alarmingly high.

Objective This systematic review aimed to explore an association of new TR and its quantification in patients undergoing His bundle pacing (HBP). Methods A literature review was conducted using Mesh terms (His bundle pacing, tricuspid regurgitation, tricuspid valve incompetence, etc.) in PubMed, EMBASE, Web of science CINAHL, and the Cochrane Library till October 2021. Relevant studies evaluating tricuspid regurgitation in HBP were included and information regarding TR and its related factors (ejection fraction (EF) and New York Heart Association (NYHA) class) were retrieved from the eligible studies. Results Out of 196 articles, 10 studies met the inclusion criteria, which consisted of 546 patients with HBP. The mean age of the patients ranged between 61.2 ± 12.3 and 75.1 ± 7.9 years with 54.1% males. The overall implant success rate was 79.2%. Only one study reported a 5% incidence of TR, while 9 studies reported no new TR after HBP. Four studies reported overall decrease in TR by 1 grade and 3 studies demonstrated increased TR from baseline. Two studies showed no change from baseline TR. Conclusion HBP causes improvement in TR grade after HBP for cardiac resynchronization therapy (CRT) as well as atrioventricular block (AVB). Further studies in the form of randomized controlled trials are required to further evaluate the effect of HBP on tricuspid valve functioning.

Background Affections of the gallbladder remain exceedingly ubiquitous and often warrant surgical intervention. The histopathological patterns represent a spectrum, ranging from cholecystitis to gallbladder carcinoma. The present study aims to delineate the occurrence of various gallbladder histopathologies in a tertiary care hospital in Pakistan.
