Background: Body Mass Index (BMI) has been shown to be an independent predictor of survival following lung resection surgery. This study aimed to quantify the short to mid-term impact of abnormal BMI on postoperative outcomes. Methods: Lung resections at a single institution were examined between 2012-2021. Patients were divided into low BMI (30). Postoperative complications, length of stay, 30- and 90-day mortality were examined. Results: 2424 patients were identified. 2.6% (n=62) had a low BMI, 67.4% (n=1634) had a normal/high BMI and 30.0% (n=728) had an obese BMI. Overall postoperative complications were higher in the low BMI group (43.5%) when compared to normal/high (30.9%) and obese BMI group (24.3%) (p=0.0002). Median length of stay was significantly higher in the low BMI group (8.3 days) compared to 5.2 days in the normal/high and obese BMI groups (p

An aortic dissection is a condition resulting from a tunica intima tear of the aortic wall creating a ‘false lumen’. An acute Stanford type A (involves the aortic arch and/or ascending aorta) aortic dissection requires emergency surgical repair. To our knowledge, we report the first case in the literature where the treatment for an acute type A aortic dissection was intentionally delayed. This was decided following a multidisciplinary team discussion where it was agreed that the patient’s active hepatitis C infection should be treated prior to surgery. The patient re-presented to the hospital 4 months later with acute dyspnoea and orthopnoea where he was diagnosed with an acute-on-chronic type A aortic dissection with trachea compression. This was successfully treated with emergency surgery. However, the patient suffered residual dyspnoea, likely due to phrenic nerve injury demonstrating the impact of untreated aortic arch distension on the neighbouring trachea and phrenic nerve.

Introduction: The impact of Covid-19 on outcomes of In-hospital cardiac arrest IHCA remains unclear. Aims & Methodology: We, conducted a retrospective cohort study to compare the characteristics and outcome of CPR in Covid positive V/s Covid negative patients, at our institute. Data were retrieved from a review of the medical records of all patients who underwent cardiac arrest during the pandemic period. Taking Covid-19 as the exposure variable, our sample population was divided into two cohorts. Results: Eighty patients who underwent CPR were included in the study with;40 patients in each group. The mean age was 61 in the positive group and 65 in the negative group. The male to female ratio was equal in the covid positive group but the male population was higher in the negative group. (77%). The most frequent comorbidities were the same (Diabetes, hypertension, and ischaemic heart disease) in both groups. All of the patients had ARDS in Covid positive group while septic shock was the commonest diagnosis (48.9%) in the negative group. In the positive group, 74% of patients were in high dependency unit (HDU) and 26% were in ICU. In the negative group,94% of patients were in HDU and 6% in ICU. The initial rhythm was Pulseless electrical activity (PEA) in 52% of the positive group and all of the patients (100%) in the negative group. Eight percent of covid positive patients had shockable rhythm while remaining had asystole. The median duration of CPR was 15 minutes in the positive group and 17 minutes in the negative group. Although the return of spontaneous circulation (ROSC) was achieved in 14% of patients in covid positive, none of them survived to discharge. In the negative group, 30% of patients achieved ROSC while survival to discharge was 15%. The odds of mortality were 6.88 [95% confidence interval (CI)0.789-60] times higher in COVID-19-positive patients, compared to negative patients. Conclusions: Covid-19 infection is associated with poor outcomes in IHCA compared to non-covid illnesses.

OBJECTIVE To compare peri-operative practices and complications in ovarian cancer patients undergoing upfront surgery for primary disease under enhanced recovery after surgery protocol and traditional practices. METHODS The retrospective cross-sectional study was done at the gynaecology departments of St Georges Hospital, United Kingdom, and the Aga Khan Hospital, Pakistan, and comprised data of an equal number of ovarian cancer patients from each centre who underwent ovarian cancer surgery from January 2015 to December 2016. The former centre practiced the enhanced recovery after surgery protocol, while the latter centre followed traditional practices. Data was analysed using SPSS 19. RESULTS Of the 100 patients, there were 50(50%) in each group. Baseline variables were comparable except for diabetes which was more prevalent in the local group (p=0.03). Mechanical bowel preparation was performed in 47(94%) of local patients compared to 1(2%) in the other group, while the duration for nil-per-mouth status as well as the use of nasogastric tube and peritoneal drain were significantly different (p
