Retail Chicken Carcasses as a Reservoir of Multidrug-Resistant .

is a major cause of foodborne disease outbreaks worldwide, mainly through poultry. Recently, there has been an increase in multidrug-resistant (MDR) infections globally. The increased drug resistance results in increased costs and poorer health outcomes due to unavailability or delayed treatment. This study aims to determine the prevalence of in retail raw chicken meat and identify their antimicrobial resistance profiles. A total of 270 retail raw chicken carcasses (local and imported) were collected from three hypermarket chains in Qatar between November 2017 and April 2018. Thirty carcasses were contaminated with (11.11%). The prevalence of in locally produced chicken was higher than in imported chicken (OR = 2.56, 95% CI: 1.18-5.53,  = 0.016). No significant differences were found between the prevalence and storage temperature or hypermarket chain. The highest resistance rates in the isolates were reported to tetracycline (73.7%) followed by nitrofurantoin (53.3%), ampicillin (50%), amoxicillin-clavulanic acid, ceftriaxone (26.7%), and ciprofloxacin (23.3%). Eight isolates were potential extended-spectrum β-lactamase-producers, all in imported frozen chicken ( < 0.0001). Additionally, 43.3% of the isolates were MDR and associated with frozen chicken (OR = 16.88, 95% CI: 2.55-111.47,  = 0.002). The findings indicate that while the prevalence of in retail chicken in Qatar is moderate, a large proportion of them are MDR.This research was funded by, Biomedical Research Centre, Qatar University, grant number “BRC-2018-ID-01 to Nahla O.

A simple statistical test of taxonomic or functional homogeneity using replicated microbiome sequencing samples

One important question in microbiome analysis is how to assess the homogeneity of the microbial composition in a given environment, with respect to a given analysis method. Do different microbial samples taken from the same environment follow the same taxonomic distribution of organisms, or the same distribution of functions? Here we provide a non-parametric statistical “triangulation test” to address this type of question. The test requires that multiple replicates are available for each of the biological samples, and it is based on three-way computational comparisons of samples. To illustrate the application of the test, we collected three biological samples taken from different locations in one piece of human stool, each represented by three replicates, and analyzed them using MEGAN. (Despite its name, the triangulation test does not require that the number of biological samples or replicates be three.) The triangulation test rejects the null hypothesis that the three biological samples exhibit the same distribution of taxa or function (error probability ≤0.05), indicating that the microbial composition of the investigated human stool is not homogenous on a macroscopic scale, suggesting that pooling material from multiple locations is a reasonable practice. We provide an implementation of the test in our open source program MEGAN Community Edition

Is the Rehbein procedure obsolete in the treatment of Hirschsprung’s disease?

Contains fulltext : 87916.pdf (publisher's version ) (Closed access)PURPOSE: After 25 years of practice and positive results of the Rehbein-procedure (RB) for children with Hirschsprung Disease (HD), we changed to the less invasive transanal endorectal pull through (TERPT). The aim of this study was to compare short- and mid-term complications of these two procedures in our patients with HD. METHODS: Retrospective data of 50 HD patients were analyzed. Of these patients, 25 underwent RB (2000-2006) and in 25 the TERPT was performed (2005-2009). Medical records were reviewed to score complications and outcomes. Differences were analyzed using Chi-Square and Mann-Whitney U tests. RESULTS: All RB patients (100%) were given a colostomy compared with four patients (16%) in the TERPT group (p < 0.001). The average age at surgery in the RB group was 191 days whereas this was 72 days in the TERPT group (p < 0.01). The mean length of time of surgery in the RB group (158 min) was not significantly different from that in the TERPT group (183 min). Ganglion cells were located in all specimens at the proximal end of the specimens. The median time to first feeding significantly decreased from 2 days (range 1-11) in the RB group to 1 day (range 1-3) in the TERPT group (p < 0.01). The median length of hospital stay decreased in the TERPT group (8 days) compared with the RB group (10 days) (p < 0.001). There was a significant reduction in postoperative obstructive symptoms during the first 6 months in the TERPT group (48%) compared with the RB group (84%) (p = 0.016). Postoperative enterocolitis decreased from 40% in the RB group to 24% in the TERPT group although this was not statistically significant. CONCLUSIONS: The introduction of TERPT reduced the need for colostomies; it shortened days to first feeding after surgery and reduced hospital stay. It also improved short-term outcome with less obstructive symptoms. We recommend TERPT surgery as a first choice in children with HD. we consider the RB now to be obsolete.1 november 201

Detection of some Food Poisoning Bacteria from Milk Utensils and Dairy Products in Port-said Governorate, Egypt

The aim of this study is to determine the possibility of transmission of some food poisoning bacteria (Staphylococcus aureus, Streptococcus spp., Escherichia coli and Proteus spp.) from the surfaces of equipment and utensils used in small dairy shops for production of dairy products to the final dairy products through microbiological examination of 90 swabs which were collected from the surfaces of equipment and utensils in small dairy shops from different localities at Port-said governorate, Egypt, in addition to 45 of each commercial small scale yoghurt and rice with milk pudding samples collected from the same small dairy shops. The results showed that the mean values for Staphylococcus aureus counts were 4.7×10⁵±1.0×10⁵ cfu/g, 3.9×10⁵±8.8×10⁴ cfu/g and 9.4×10⁵±2.3×10⁵ cfu/g in swabs, yoghurt and rice with milk pudding samples, respectively, and The mean values for Streptococcus spp. were 2.2×10⁶±2.6×10⁵ cfu/g,1.4×10⁶±3.1×10⁵cfu/g and 3.2×10⁶±5.6×10⁵ cfu/g in swabs, yoghurt and rice with milk pudding samples, respectively, While the mean values of Escherichia coli were 1.7×10²±2.6×10¹ cfu/g and 1.2×10²±3×10¹ cfu/g in swabs and yoghurt samples, respectively, with absence in examined rice with milk pudding samples. Proteus spp. couldn’t be detected in any examined samples. It could be concluded that the microorganisms which isolated from yoghurt and rice with milk pudding samples have already found on equipment and utensils used in its manufacture, this may confirm cross-contamination from equipment and utensils surfaces to yoghurt and rice with milk pudding as a final dairy product of small dairy shops

Potentially inappropriate prescriptions in heart failure with reduced ejection fraction: ESC position statement on heart failure with reduced ejection fraction-specific inappropriate prescribing

Heart failure (HF) is a chronic debilitating and potentially life-threatening condition. HF patients are usually at high risk of polypharmacy and consequently, potentially inappropriate prescribing leading to poor clinical outcomes. Based on the published literature, a comprehensive HF-specific prescribing review tool is compiled to avoid medications that may cause HF or harm HF patients and to optimize the prescribing practice of HF guideline-directed medical therapies. Recommendations are made in line with the last versions of European Society of Cardiology (ESC) guidelines, ESC position papers, scientific evidence, and experts’ opinions
