the CHI-SQUARE TEST FOR STUDENT'S T DISTRIBUTION USING SELECTIVE ORDER STATISTICS

Sameer Al-Subh — 2024-07-18

The aim of the present study is to investigate the power and efficiency of the chi-square test for goodness-of-fit (GOF)for Student's t under the Selective Order Statistics (SOS). A simulation study compares the chi-square test's efficiency based on an SOS with its counterpart in a simple random sampling (SRS).The chi-square test is found to be more powerful under the SOS when compared to SRS. However, for the case of median SOS, the test is found to be more powerful under SRS.

Perceptions of Occupational Health Hazards Among Jordanian Nurses: A cross-Sectional Study

نهى الزيادين — 2024-07-18

Occupation health pertains to the health of employees in relation with their workplaces, and is aimed at the prevention of job-related injuries and illnesses. However, given the significance of occupational health and the possible adversarial effects of occupational hazards to the nursing team, there is paucity of evidence on the level of awareness, knowledge and attitudes of nurses towards occupational hazards in the workplace. The aim of this study is to measure levels of perceptions of occupational hazards, and to identify relationships and differences on perceptions of occupational hazards based on sociodemographic characteristics, the study employed cross-sectional, descriptive method. A valid and reliable 13-item questionnaire was used to measure perceptions of occupational hazards.

Results showed that nurses had high levels of perceptions of occupational hazards. Nurses with longer lengths of work experiences had higher levels of perceptions of occupational hazards than nurses with shorter lengths of work experiences..the study concluded that hospitals should implement strategies that can support nurses in sustaining high levels of perceptions of occupational hazards, and should find ways to retain nurses within the hospital workforce. Future research can examine personal- and organizational-level factors that can impede or facilitate perceptions of occupational hazards, and explore how perceptions of occupational hazards translate to actual injuries sustained at work, quality of workplace environment, quality of work life, job performance, patient satisfaction, and other relevant organizational and clinical outcomes.

Food Safety knowledge and Handling Practices among Jordanian University Students

Nawal Alsakarneh — 2024-11-10

This study assessed food safety knowledge and practices (KP) among 461 university students in Jordan, comparing health-related and non-health-related students. A cross-sectional survey using a questionnaire evaluated demographics, food safety knowledge, and handling practices. Health-related students scored higher in food safety knowledge with significant differences between them (mean: 4.95 ± 2.32) compared to non-health-related students (mean: 3.73 ± 1.92, p < 0.001).

Health-related female students also demonstrated better knowledge (mean: 6.70 ± 1.95) than males (mean: 6.03 ± 2.38, p = 0.008). Significant differences were found, especially among non-health-related students.

Common issues included inadequate food storage knowledge and reliance on feel-touch tests instead of thermometers, leading to undercooking and foodborne infections. Additionally, the COVID-19 pandemic temporarily improved practices, though post-pandemic declines were noted in handwashing and thermometer use.

This study highlights the need for targeted interventions, particularly for male students not enrolled in health-related fields. Targeted educational programs and practical training focusing on food safety can significantly improve both knowledge and practice, reducing health risks. Including food safety modules in non-health disciplines can help bridge the gap between academic knowledge and practical application.

Nutritional Status of Patients with Polycystic Ovary Syndrome (PCOS) in Irbid Governorate, Jordan: A Case-Control Study

شهد ردايده — 2024-11-10

Polycystic Ovary Syndrome (PCOS) is a crucial infertility problem among women in the world; especially Arab women. The main objective of this case-control study was to perform anthropometric, biochemical, clinical and nutritional assessment among PCOS patients. The study population composed of 60 Jordanian women aged 19–39 years, and classified into two groups: 30 were cases (PCOS patients) and 30 were control group (Healthy women). Results of the study indicated that the Body Mass Index (BMI) were significantly higher among PCOS patients than healthy women. Furthermore, significant differences were shown in the mean values of Luteinizing Hormone (LH) and (LH): Follicle-Stimulating Hormone (FSH) (LH:FSH) ratio which were higher among PCOS patients with a p=0.01 and p=0.03, respectively. Also, significant differences between PCOS patients and healthy women were shown for three clinical manifestations of PCOS including infertility, sleep apnea, and eating disorders. Moreover, the findings of the validated food frequency questionnaire (FFQ) revealed no significant differences between two study groups in the consumption of macronutrients and total energy intake. It is obviously concluded from the study that PCOS is remarkably responsible for substantial variations in anthropometric and biochemical measurements, hormonal levels, and clinical features among PCOS patients.

The influence of nutrition on brain aging: A Comprehensive Review

سناء غنيمات — 2024-11-10

Purpose: Aging is characterized by a progressive decline in physiological functions, including those of the brain. As individuals age, cognitive and emotional functionalities are subject to change, Consequently, it is essential to consider both cognitive abilities and emotional functioning when examining the effects of aging on the brain.

Objectives: The objective is to synthesize current scientific evidence on the relationship between nutrition and brain aging, with a specific focus on cognitive abilities as a measure of brain function.

Methodology: A systematic review was conducted on nine studies. The PRISMA statement standards were adhered to in this systematic review.

Findings: The findings showed how important it is for people to change their diets to prevent the onset and progression of various comorbidities and to encourage healthy aging. The findings of the study included in this Comprehensive review indicate that good aging and a higher quality of life may be achieved by abstaining from bad behaviors, particularly those related to food.

Conclusions: The current body of study indicates a relationship between nutrition and brain aging, but additional studies are necessary to expand our understanding of these complex interactions and to develop clear dietary recommendations to support cognitive health across the lifespan.
