Variation in practice and patient outcomes for patients undergoing emergency laparotomy has been identified through the UK National Emergency Laparotomy Audit (NELA), with 30-day mortality ranging from 11 to 15%. A correlation between preoperative haemodynamic parameters and increased postoperative mortality has been demonstrated by both NELA and other observational studies. The association between intraoperative haemodynamic parameters and overall postoperative morbidity has not been evaluated in EL patients. The aims of our study were to investigate the association between perioperative haemodynamic and logistic parameters and postoperative morbidity in a tertiary referral university hospital; and to compare our outcomes to that of the NELA data. A retrospective analysis correlating a range of perioperative parameters with Comprehensive Complication Index (CCI) among 86 patients who underwent EL during 2018 was conducted. Mean age was 64 years (SD 16). Median CCI was 27 [9-45], and 30-day mortality was 11.7%. Several intraoperative parameters correlated with CCI on univariate analysis. On multivariate analysis, ASA status (P = 0.005) and unplanned escalation to postoperative intensive care (P = 0.03) were independently associated with CCI. Our study shows a correlation between ASA status and unplanned escalation to ITU with increased postoperative morbidity in patients undergoing emergency laparotomy. We did not demonstrate an independent correlation between intraoperative parameters and postoperative morbidity. These findings warrant confirmation in a larger scale observational study. Outcomes in our institution are comparable to those seen in the NELA.

Objective: Assess the frequency of different genotype of hormone sensitive lipase among individuals with different waist hip circumference and assess the risk of the genetic polymorphism of hormone sensitive lipase C-60G on abdominal obesity. Study Setting: The Cross-sectional study was conducted in the Biochemistry department of RAKMHSU for 4 months from (November 2017 – February 2018).

In Pakistan, 6-7% of patients with diabetes suffer from diabetic foot ulceration. Objectives: Our primary objective was to explore the frequency of diabetic foot amputations, and the secondary objective was to calculate the economic burden of these preventable surgeries on the health budget of the provincial government. Materials & Methods: It was a retrospective cross-sectional observational study conducted after obtaining approval from the Ethical Review Committee of Allied hospital, Faisalabad Medical University. The data of diabetic foot patients who underwent amputations between July 2017 and December 2017 were retrieved from three Surgical Units (I, II & III), using a purposive sampling technique. All amputations carried out for reasons other than diabetic foot were excluded. The direct medical cost of one diabetic foot amputation was calculated via a l...

Routing protocol is considered as the most important element of MANET. However, media streaming over MANET is a quite demanding task. In this paper the performances of MANET routing protocols have been investigated for video applications. Some popular routing protocols namely Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Temporally-Ordered Routing Algorithm (TORA), Optimized Link State Routing Protocol (OLSR), and Geographic Routing Protocol (GRP) have been considered in this paper. A comparative performance analysis of these routing protocols has been presented in this paper for supporting video streaming applications.

This descriptive cross sectional survey was done in displaced population of Jalozai camp Nowshera from February to September 2010. Systematic Random Sampling was done (10% of Phase II Population). Study unit was a single family residing in the camp. A customized structured questionnaire was administered to households and information as recorded by the researchers. Informed consent and confidentiality was maintained while interviewing the household. Although 97% (n=111) families were using soap for bathing but surprisingly none of them were on required Sphere Standards. Similarly 93% (n=107) were using laundry soaps and 49% (n=56) were using washing powder but again were not fulfilling the standards. It was discovered based on our survey that 64% (n=71) displaced people were not using anything for cleaning their children and none we...
