Association between Intraoperative Bactibilia and Postoperative Septic Complications in Biliary Tract Surgery

Background: The present study intended to clarify the role of biliary bacteria in the development of postoperative septic complications in patients undergoing biliary operations and need for antibiotic prophylaxis.Patient and methods: A total of 121 patients with various biliary tract diseases underwent various surgical interventions. The relation between contaminated ductal bile and postoperative septic complications was analyzed prospectively.Results: 42/121 patients were bile culture positive (B+) while 79/121 patients were bile culture negative (B-).14 patients in B (+) group developed septic complications compared to only 3 patients in B (-) group (P = 0.0001). In B (+) group, bacteria found in ductal bile were also detected in infected sites of 85% of patients with septic complications. In B (+) group postoperative antibiotic modification significantly (p=0.001) reduced infectious complications.Conclusion: Infected bile plays a critical role in development of post operative septic complications. Hence patients with risk factors for bactibilia should receive prophylactic antibiotics covering endogenous gram negative organisms which should be modified in postoperative phase according to the results of sensitivity. However this issue requires further investigations by studies conducted on similar lines

Regulatory hypothesis and bank dividend payouts: Empirical evidence from Italian banking sector

This study examines the regulatory hypothesis for bank dividend payouts using a panel dataset of 229 Italian banks over the period 2005–2012. Regulatory hypothesis suggests that undercapitalized banks face more regulatory pressure for increasing capital levels by paying lower amount of dividends. Empirical results support the regulatory hypothesis by finding that the Italian banks having lower equity to total assets ratios or lower regulatory capital ratios retain more profits and pay lower amount of dividends. Results also suggest that dividend payer banks try to maintain dividends at previous level by not skipping or reducing dividends. Results further support that Fama and French (2001)'s three characteristics of dividend payers are also applicable to banks. That is, big-in-size, more profitable and low growth Italian banks pay higher amount of dividends. Findings of this study have important implications for recent regulatory proposals that suggest a direct regulation of dividends. A direct regulation of dividends, on one hand, and regulatory pressure on dividend payout decisions through capital requirements, on the other hand, may have unintended consequences for dividends as signaling and agency cost reducing tools

GOAT-A POTENTIAL DAIRY ANIMAL: PRESENT AND FUTURE PROSPECTS

1UAF Sub-Campus Toba Tek Singh, University of Agriculture, Faisalabad Goats are well-admired and documented worldwide for providing food in terms of milk and meat and their products. They are playing a key role in supporting millions of people who are poor, landless and living in the rural areas. Goats are not only well-embedded in the culture but socially acceptable too for reducing global poverty in particularly for the developing nations. A goat is universally called as "Poor man's cow" Globally about 90 % goats are found in the developing world. Asia alone produces about 80 % goat milk. Pakistan at present supports 56.7 millions head of goats consisting of about 25 well-recognized breeds found in different regions of the country. Goats annually contribute approximately 275 thousand tonnes of meat, 851 thousand tonnes of milk, 25 million skins and 21.4 thousand tonnes of hair to the national economy. They are also a source of foreign exchange and contribute 2.5 % of the annual milk production. Majority of goats, however, are meant for meat with the exception of some milch breeds. These typical indigenous milch breeds include Beetal, Dera Din Panah (DDP), Naachi, Damani, and Kamori. These dairy goats constitute about five million of the total goat population in the country. Usually small flocks of sheep and goats are raised together both in plains and subhilly areas. The goats are being kept under three main production systems viz: nomadic, transhumant, sedentary and household. Major feed resources available for goats are mainly ranges (60 %), while other feeding material available to these animals is along canal/river banks; pastures, roadside grazing, crop residues, tree leaves, pods etc. Goats are naturally bred under field conditions. Despite having their crucial role in rural lives throughout the world they have not been properly addressed the way they really deserve. The present paper will review the dairy potential of local dairy goat breeds along with their future scope as a dairy animal

Prevalence of Muscle Dysmorphia and Associated Health Activities in Male Medical Students in Karachi, Pakistan

Background: Muscle Dysmorphia (MD) is a subtype of body dysmorphic disorder (BDD) and is currently classified under anxiety disorders (subheading: Obsessive-compulsive disorder) in DSM 5. MD is hypothesized to affect the self-esteem and social outlook of the younger generation. MD shows a higher rate in males and may influence their self-confidence rendering them more prone towards using steroids, supplementary proteins and other drugs to alter their physical outlooks as shown in previous studies. This problem has been on the rise lately due to revolutionary advancement in the media and film industry and the abrupt changes about the standards of physical good looks and body shapes. With the lack of studies done in our population, our study will be helpful to consider the prevalence of the disease in our setting and increase awareness in the general public and clinicians. We hope to help clinicians/ therapists find better options in managing the disease. Materials: We performed a cross-sectional study with a sample size of 246 medical school students in Karachi to collect data through self-administered questionnaires. We used the DSM 5 criteria for the diagnosis of BDD and additional questions on the presence of MD. Nutritional habits, exercise routines, use of supplements and drugs were also obtained for exploratory analysis. Results: Our study predicted the prevalence of MD to be 25%. Other main findings included statistical significant associations between MD and the thoughts and practice of steroid use for muscularity. Conclusion: MD is an underdiagnosed and often unrecognized disease that we believe has significant consequences for the young male population. Further work is needed on this in our part of the world. Our research, we believe, can be a stepping stone for further studies that would incorporate wider populations

Novel VPS13B Mutations in Three Large Pakistani Cohen Syndrome Families Suggests a Baloch Variant with Autistic-Like Features.

BackgroundCohen Syndrome (COH1) is a rare autosomal recessive disorder, principally identified by ocular, neural and muscular deficits. We identified three large consanguineous Pakistani families with intellectual disability and in some cases with autistic traits.MethodsClinical assessments were performed in order to allow comparison of clinical features with other VPS13B mutations. Homozygosity mapping followed by whole exome sequencing and Sanger sequencing strategies were used to identify disease-related mutations.ResultsWe identified two novel homozygous deletion mutations in VPS13B, firstly a 1 bp deletion, NM_017890.4:c.6879delT; p.Phe2293Leufs*24, and secondly a deletion of exons 37-40, which co-segregate with affected status. In addition to COH1-related traits, autistic features were reported in a number of family members, contrasting with the "friendly" demeanour often associated with COH1. The c.6879delT mutation is present in two families from different regions of the country, but both from the Baloch sub-ethnic group, and with a shared haplotype, indicating a founder effect among the Baloch population.ConclusionWe suspect that the c.6879delT mutation may be a common cause of COH1 and similar phenotypes among the Baloch population. Additionally, most of the individuals with the c.6879delT mutation in these two families also present with autistic like traits, and suggests that this variant may lead to a distinct autistic-like COH1 subgroup

Angiotensin-Converting Enzyme Gene I/D Polymorphism Is Associated With Systemic Lupus Erythematosus Susceptibility: An Updated Meta-Analysis and Trial Sequential Analysis

Angiotensin-converting enzyme (ACE) gene is indispensable for endothelial control and vascular tone regulatory systems, usually affected in Systemic Lupus Erythematosus (SLE). ACE insertion/deletion (I/D) polymorphism may influence the progress of SLE. Earlier studies have investigated this association without any consistency in results. We performed this meta-analysis to evaluate the precise association between ACE I/D polymorphism and SLE susceptibility. The relevant studies were searched until December, 2017 using Medline (PubMed), Google-Scholar and EMBASE search engines. Twenty-five published studies involving 3,308 cases and 4,235 controls were included in this meta-analysis. Statistically significant increased risk was found for allelic (D vs. I: p = 0.007; OR = 1.202, 95% CI = 1.052–1.374), homozygous (DD vs. II: p = 0.025; OR = 1.347, 95% CI = 1.038–1.748), dominant (DD+ID vs. II: p = 0.002; OR = 1.195, 95% CI = 1.070–1.334), and recessive (DD vs. ID+II: p = 0.023; OR = 1.338, 95% CI = 1.042–1.718) genetic models. Subgroup analysis stratified by Asian ethnicity revealed significant risk of SLE in allelic (D vs. I: p = 0.045; OR = 1.238, 95% CI = 1.005–1.525) and marginal risk in dominant (DD+ID vs. II: p = 0.056; OR = 1.192, 95% CI = 0.995–1.428) models; whereas, no association was observed for Caucasian and African population. Publication bias was absent. In conclusion, ACE I/D polymorphism has significant role in overall SLE risk and it can be exploited as a prognostic marker for early SLE predisposition

Cardiovascular outcomes and trends of Transcatheter vs. Surgical aortic valve replacement among octogenarians with heart failure: A Propensity Matched national cohort analysis.

Background: Heart failure (HF) is a complex clinical syndrome with symptoms and signs that result from any structural or functional impairment of ventricular filling or ejection of blood. Limited data is available regarding the in-hospital outcomes of TAVR compared to SAVR in the octogenarian population with HF. Methods: The National Inpatient Sample (NIS) database was used to compare TAVR versus SAVR among octogenarians with HF. The primary outcome was in-hospital mortality. The secondary outcome included acute kidney injury (AKI), cerebrovascular accident (CVA), post-procedural stroke, major bleeding, blood transfusions, sudden cardiac arrest (SCA), cardiogenic shock (CS), and mechanical circulatory support (MCS). Results: A total of 74,995 octogenarian patients with HF (TAVR-HF n = 64,890 (86.5%); SAVR n = 10,105 (13.5%)) were included. The median age of patients in TAVR-HF and SAVR-HF was 86 (83-89) and 82 (81-84) respectively. TAVR-HF had lower percentage in-hospital mortality (1.8% vs. 6.9%;p < 0.001), CVA (2.5% vs. 3.6%; p = 0.009), SCA (9.9% vs. 20.2%; p < 0.001), AKI (17.4% vs. 40.8%); p < 0.001), major transfusion (26.4% vs 67.3%; p < 0.001), CS (1.8% vs 9.8%; p < 0.001), and MCS (0.8% vs 7.3%; p < 0.001) when compared to SAVR-HF. Additionally, post-procedural stroke and major bleeding showed no significant difference. The median unmatched total charges for TAVR-HF and SAVR-HF were 194,561$and 246,100$ respectively. Conclusion: In this nationwide observational analysis, TAVR is associated with an improved safety profile for octogenarians with heart failure (both preserved and reduced ejection fraction) compared to SAVR

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
