Evaluation of performance and estimation of genetic parameters for milk yield and reproductive traits in Awassi and Asaf sheep breeds and crosses in the Palestinian territory.

This study aimed to estimate genetic parameters, including heritability and repeatability, for milk yield and prolificacy in sheep. It included 3682 records from 1837 ewes across various breeds: Awassi, Assaf, and Awassi x Assaf crosses, two Awassi lines: Improved Awassi, AFEC Awassi. The study measured total milk yield (TMY), yield up to 120 days (TMY120), and yield up to 150 days (TMY150), alongside reproductive traits: litter size (LS), number of lambs born alive (NLBA), and lambing interval (LI).

Alarm fatigue and perceived stress among critical care nurses in the intensive care units: Palestinian perspectives.

Objective: The frequency of alarms generated by monitors and other electro-medical devices is undeniably valuable but can simultaneously escalate the workload for healthcare professionals, potentially subjecting intensive care unit nurses to alarm fatigue. The aim of this study is to investigate alarm fatigue and stress levels among critical care nursing personnel. Additionally, the study aims to assess predictors for both alarm fatigue and perceived stress.

Evaluation of Clinical Competence and Job Satisfaction and Their Related Factors Among Emergency Nurses in Palestinian Hospitals.

Introduction: Nurses are responsible for providing primary care to millions of patients, and emergency nurses serve on the frontline in providing care for mildly to severely critically ill patients.

Objectives: This study aims to assess and evaluate the clinical competence and its related factors among emergency nurses in Palestinian hospitals.

Methods: A cross-sectional study was conducted among 170 nurses working in the emergency units of hospitals in the West Bank, Palestine.

Early perception, behavior, knowledge, and preventive practices related to COVID-19 among Palestinians.

It is necessary to understand early perception, behavior, and knowledge of coronavirus disease 2019 (COVID-19) and preventive practices in relation to suggested policies and information accessible to the Palestinian population during the early stages of the pandemic. The aim of this research is to contribute to this understanding for the purpose of affecting future practical preventive policies that can be implemented and adapted in Palestine in order to shape a new reflective practices model to face any future epidemic crisis of any type. A cross-sectional design was used to conduct the study over 3 weeks in April 2020 and an online survey was disseminated in all areas of Palestine.

Delirium in Intensive Care Units: Perceptions of Physicians and Nurses.

Delirium is an indicator of morbidity and mortality in intensive care unit (ICU) patients. It can lead to negative outcomes and longer hospital stays, thus increasing hospital costs. Despite national recommendations for daily assessment of delirium, it remains underdiagnosed.

Knowledge, Perceptions, and Prevention Practices among Palestinian University Students during the COVID-19 Pandemic: A Questionnaire-Based Survey.

The purpose of this study is to offer a timely understanding of university students' knowledge, perception, and preventative practices related to COVID-19 in Palestine and to determine affecting factors (gender, region, and type of locality). A cross-sectional design was used and data was collected over 2 weeks in April 2020 through an online survey. A total of 484 surveys were collected from students from different Palestinian universities.

Case-Control Study of Risk Factors and Self-Care Behaviors of Foot Ulceration in Diabetic Patients Attending Primary Healthcare Services in Palestine.

The purpose of this study is to identify certain sociodemographic, lifestyle, self-care, and foot examination factors that predict the development of diabetic foot ulcers in Palestine. A case-control study was performed in Palestine in 2019. The control group consisted of diabetic patients without foot ulceration (NFU).

Static and Fatigue Loading of Veneered Implant-Supported Fixed Dental Prostheses.

Purpose: This study aimed to compare the load to failure and the probability of survival of porcelain fused to zirconia (PFZ) three-unit, implant-supported, fixed dental prostheses (FDPs) to those of indirect composites veneered to either zirconia (CVZ) or milled fiber-reinforced composite (FRC) frameworks under static and fatigue loading.

Materials And Methods: One-hundred and twenty posterior three-unit FDP (second premolar pontic) frameworks were fabricated via milling from a single Standard Tessellation Language (STL) file. The FDPs were divided into three groups.

Clinical and socio-demographic parameters contributing to treatment incompliance in Palestinian patients with diabetes.

Background: This research study investigates the degree of medication-related satisfaction experienced by Palestinian patients with diabetes. In addition, this study further assesses the association between certain clinical and socio-demographic factors and the degree of satisfaction among the patients.

Methods: This cross-sectional, descriptive study design consisted of 415 randomly selected patients from the Palestine Medical Complex (PMC), the Palestinian Ministry of Health Clinics, and from the Palestinian Diabetes Institute (also known as: Al-Bireh Medical Center).

[Not Available].

Background: Vascular closure devices (VCD) make it possible to rapidly remove the introducer sheath from an arterial access, thereby reducing the length of time in hemostasis, the time patients are restricted to their beds, and the number of puncture site complications.

Objectives: To evaluate the efficacy and possible complications associated with use of an arterial occlusion device compared with manual compression.

Methods: This was a prospective, randomized, longitudinal study of 20 patients conducted from December 2014 to July 2015 in Maringá, PR, Brazil.

Use of narrow-diameter implants in the posterior jaw: a systematic review.

Statement Of Problem: Evidence is limited on the efficacy of narrow-diameter implants (NDIs) in the posterior jaw.

Purpose: The purpose of this systematic review was to assess the survival of NDIs and provide guidelines for their safe use.

Materials And Methods: Electronic search of the English-language literature enriched by hand search to identify suitable publications was made.

Detecting selection in population trees: the Lewontin and Krakauer test extended.

Detecting genetic signatures of selection is of great interest for many research issues. Common approaches to separate selective from neutral processes focus on the variance of F(ST) across loci, as does the original Lewontin and Krakauer (LK) test. Modern developments aim to minimize the false positive rate and to increase the power, by accounting for complex demographic structures.

Linkage disequilibrium interval mapping of quantitative trait loci.

Background: For many years gene mapping studies have been performed through linkage analyses based on pedigree data. Recently, linkage disequilibrium methods based on unrelated individuals have been advocated as powerful tools to refine estimates of gene location. Many strategies have been proposed to deal with simply inherited disease traits.

A comparison between methods for linkage disequilibrium fine mapping of quantitative trait loci.

We present a maximum likelihood method for mapping quantitative trait loci that uses linkage disequilibrium information from single and multiple markers. We made paired comparisons between analyses using a single marker, two markers and six markers. We also compared the method to single marker regression analysis under several scenarios using simulated data.

Linkage disequilibrium fine mapping of quantitative trait loci: a simulation study.

Recently, the use of linkage disequilibrium (LD) to locate genes which affect quantitative traits (QTL) has received an increasing interest, but the plausibility of fine mapping using linkage disequilibrium techniques for QTL has not been well studied. The main objectives of this work were to (1) measure the extent and pattern of LD between a putative QTL and nearby markers in finite populations and (2) investigate the usefulness of LD in fine mapping QTL in simulated populations using a dense map of multiallelic or biallelic marker loci. The test of association between a marker and QTL and the power of the test were calculated based on single-marker regression analysis.
