The impact of incorporating dried cafeteria leftover food on growing APRI rabbits productivity, profitability and meat quality.

This study was conducted to investigate the effect of dried cafeteria leftover food (DCLF) incorporation in growing APRI rabbit diets on nutrient digestibility, live body weight, body weight gain, carcass traits, meat quality, blood parameters, and economic efficiency. Thirty-six APRI rabbits (6 weeks of age), after weaning, were randomly divided into three groups (12 rabbits/group, 613 ± 5 g). During the experiment, rabbits aged 6-14 weeks participated in the experiment. An approximate isocaloric and isonitrogenous composition was achieved in three pelleted experimental diets. For the rabbit groups D1 (as the control), D2, and D3, DCLF was added at doses of 0%, 17.5%, and 35%, respectively. Digestibility trails were carried out at the end of the feeding experiment to evaluate the nutritional and feeding values of the experimental diets. To examine the characteristics of the carcasses, the quality of the meat, the histopathological analysis, and the blood plasma parameters, three rabbits were slaughtered from each group. The results showed that the feeding values (TDN and DE), which had the greatest values, as well as the digesting coefficients for dry matter, organic matter, crude fiber, and ether extract between the D1 and D3 groups were significantly different (p < 0.05). On the contrary, the curde protein, nitrogen-free extract, and digestible crude protein of the examined diets showed no signifcant differences compared with the control diet. The level of DCLF incorporation in diets significantly (p < 0.05) increased the live body weight at 14 weeks; with D3 recording the highest values (2130.9 g) when compared to the D1 and D2 groups. A similar pattern was observed for both daily increase and total body gain (6-14 weeks). Feed conversion recorded insignificant differences among the experimental diets respecting the period 6-14 weeks of age. DCLF levels had a significant effect on dressing and giblet percentages. The chemical composition and color parameters of rabbit meat were similar (p > 0.05), except for fat%, which had the highest value in the D3 group (p < 0.05) compared to the D1 and D2 groups. Economic efficiency was improved by using DLCF up to 35% in terms of gross margin and feed cost/kg gain. In conclusion, using DCLF in the feeding system of rabbits could enhance productive performance, carcass traits, meat quality, and physiological function, as well as improve economic efficiency.

Imidacloprid effects on acetylcholinesterase and nicotinic acetylcholine receptor in Apis mellifera. Experimental and molecular modeling approaches.

Although the neonicotinoid insecticides have good selectivity towards insects rather than vertebrates, they have severe effects on honeybee production and pollination activities. Therefore, the effects of imidacloprid (IMI), the most used neonicotinoid, on the two main bioreceptors, acetylcholinesterase (AChE) and nicotinic acetylcholine receptor alpha subunit (nAChRα1) of honeybees were examined to identify their roles in honeybee toxicity and possible binding sites which assist in selecting and designing neonicotinoids. In vivo, IMI showed a high inhibitory effect on AChE (IC50 5.63 mg/L); however, the effect was much lower in vitro experiment (IC50 719 mg/L). This result induced us to examine the IMI effect on AChE gene expression which revealed that the AChE-2 gene expression was severely affected by IMI explaining the observed high enzyme inhibition. In addition, although toxicity increased by increasing exposure to IMI (LC50 2.9 mg/L after 4h and 0.75 mg/L after 48h), AChE was not elevated (IC50 5.63 and 5.52 mg/L respectively). Besides, Despite resuming most enzyme activity (77% during 2 h and 84.14% after 4 h), a high mortality level was observed with LC50 2.9 mg/L. These results reinforced that the observed high toxicity is a multifactor process. Accordingly, Molecular modeling and docking of IMI into honeybee AChE and nAChRα1were also performed to examine their possible interactions and identify the important binding sites. Results models indicated that the first two binding sites in AChE were found in the esteratic subunit in the active site explaining the observed in vitro inhibition. In nAChRα1, four of the highest five free energy binding sites are located in the large TM3-TM4 loop and one in the extracellular loops. Consequently, the present work revealed that IMI toxicity is attributed to various factors including direct interaction with both AChE and nAChRα1 as well as downregulating AChE-2 gene expression.

Assessment of Patient Safety Culture Among Nurses Working at Tertiary Care Hospitals in Aljouf Region, Saudi Arabia.

INTRODUCTION: Patient safety is a fundamental element in healthcare quality and a major challenge in achieving universal health coverage, especially in low- and middle-income countries. The first step to improve patient safety is to evaluate the safety culture in hospitals. This study aimed to investigate the patient safety culture among nurses and determine the factors affecting it. METHODS: This cross-sectional study was conducted among 423 nurses working at tertiary care hospitals in the Al-Jouf region in Saudi Arabia. RESULTS: The highest score for patient safety among nurses was for teamwork within units (16.41 ± 2.44). The lowest score was for nonpunitive response to errors (5.87 ± 1.92). In addition, 83% of the participants did not report any events in the past 12 months. More perception of patient safety was significantly higher among females than males in dimensions of teamwork within units, frequency of events reported, and staffing. Furthermore, teamwork within units, management support for patient safety, staffing, non-punitive response to errors, and handoffs and transitions were significantly higher among participants in direct contact with patients. The Hospital Survey on Patient Safety Culture (HSOPSC) scale is significantly higher among non-Saudi nurses, nurses with bachelor's education, nurses with less working hours per week, and those who had training on patient safety. CONCLUSION: The current study showed that the majority of the participants did not report any events in the past 12 months. The highest score for patient safety culture dimensions among nurses was for teamwork within units while the lowest score was for nonpunitive response to errors.

Assessment of Psychosocial Correlates and Associated Factors of Colorectal Cancer Screening among Southwestern Saudi Population: A Cross-Sectional Study.

Psychosocial correlates are one of the crucial determinants for the uptake of colorectal cancer (CRC) screening by the pre-eligible population. The present study aimed to identify the psychosocial correlates of colorectal cancer screening and determine their associated factors among the Saudi population in the Najran region, Saudi Arabia. Using a validated questionnaire, we assessed five constructs of psychosocial correlates of CRC screening among 790 participants aged 45 years and above. The five constructs were salience and coherence, cancer worries, perceived susceptibility, response efficacy, and social influence. Of the studied population, less than 50% agreed with most of the five constructs' statements, and 27.5% preferred to follow their family members' advice. Significantly higher mean scores (±SD) were identified for the male gender (7.38 ± 2.15, p = 0.027) and participants working in government sectors (7.60 ± 2.03, p = 0.027) in the cancer worries construct, while the mean (±SD) scores of perceived susceptibility were significantly higher among married participants (14.38 ± 4.10, p = 0.023) and smokers (14.95 ± 3.92, p = 0.041). Our survey results could help policymakers to implement focused health education programs for the pre-eligible population on the importance of the uptake of CRC screening. Furthermore, it is recommended to carry out exploratory mixed-method surveys in other regions of Saudi Arabia to understand the region's specific psychosocial correlates towards CRC screening.

Prevalence and Correlates of Intimate Partner Violence among Women Attending Different Primary Health Centers in Aljouf Region, Saudi Arabia.

BACKGROUND AND OBJECTIVES: Intimate partner violence (IPV) is a serious and widespread problem worldwide. IPV can seriously influence the physical, mental, sexual, and reproductive health of women as well as the welfare of their children. In the Middle East, IPV is pervasive and widely acceptable. The present study was done to determine the prevalence and correlates of IPV among women attending different primary health centers in the Aljouf region, Saudi Arabia. METHODS: A cross-sectional study was conducted among 403 Saudi women attending different primary health centers in the Aljouf region, Saudi Arabia. A structured anonymous questionnaire was distributed to the targeted population during a face-to-face interview. Data analysis was done using the SPSS program, version 24. RESULTS: The present study showed that 30.3% of the participants had been exposed to IPV over the last year. Concerning the types of violence, the present study revealed that emotional violence is the highest followed by physical and then sexual violence representing 92.6%, 67.2%, and 44.3%, respectively. The significant predictors of IPV were women with one to three children (OR = 7.322, p-value = 0.006), women with four children or more (OR = 13.463, p-value = 0.006), and women married to husbands with aggressive behavior (OR = 98.703, p-value < 0.001). Not taking the approval on marriage was significantly associated with more exposure to violence (OR = 3.190, p-value = 0.042). In addition, husband smoking status was a significant predictor for IPV (OR = 2.774, p-value = 0.012). However, women married to alcoholic drinkers had a significantly lower risk for exposure to IPV (OR = 0.108, p-value = 0.040). On the other hand, women's age, marital status, women's educational level, monthly income in RS, perception of income sufficiency, marriage duration, the age difference between women and their husband, and drug abuse status of the husband were not significant predictors of IPV (p-value ≥ 0.05). Sociocultural effects were the most frequent reason for IPV as reported by the participants (57.4%). The most common consequences of IPV were psychological problems (75.4%) and injuries (42.6%). Women's reactions to IPV were leaving home (32.8%) or no reaction (36.8%) to retain their marriage. CONCLUSIONS: IPV remains an important public health problem among married women in this study area. Urgent interventions including educational and screening programs for Saudi women are required to mitigate the problem.

Postmenopausal Symptoms and Their Correlates among Saudi Women Attending Different Primary Health Centers.

(1) Background and objectives: Due to increasing life expectancy, more than one-third of women's life can be spent in the postmenopausal period. In this period, women have different somatic, psychological, and urogenital symptoms. The present study was done to evaluate postmenopausal symptoms and their correlations among Saudi women attending different primary health centers. (2) Methods: adopting a cross-sectional study was done among 845 postmenopausal women attending different primary health centers. The menopause rating scale (MRS) was utilized to investigate the prevalence and severity of different menopausal manifestations. Data collection was done using a structured anonymous questionnaire disseminated during face-to-face interviews. Analysis of data was done utilizing the SPSS program, version 24. (3) Results: The total MRS score was 15.68 ± 6.85. The mean score of the subscales were: 5.56 ± 2.78 for the somatic domain, 6.04 ± 2.89 for the psychological domain, and 4.08 ± 2.32 for the urogenital domain. Joint and muscle pain (25.2%) and sleep problems (18.6%) were the most prevalent severe/very severe somatic symptoms. The most severe/very severe symptoms of the psychological domain were mental and physical exhaustion (20.2%) and depressed mode (19.2%), while that of the urogenital domain were sexual problems (20.1%) and bladder problems (16.3%). Significant predictors of the subscales of MRS were sociodemographic characteristics such as age, residence, marital status, educational level, and occupation. Furthermore, history of chronic diseases, parity, and menopause duration were significant predictors of the subscales of MRS. (4) Conclusion: women in the present study experience different postmenopausal symptoms. Health care providers should consider this crucial stage of women's life to help elderly women manage these different postmenopausal manifestations.

Novel coronavirus disease-related knowledge, attitudes, and practices among the residents of Al-Jouf region in Saudi Arabia.

INTRODUCTION: Efforts have been made to contain COVID-19. Human behavior, affected by knowledge and perceptions, may influence the course of disease. METHODOLOGY: A structured questionnaire was used to collect data from 422 participants. It consisted of 28 questions in four sections; seven questions about sociodemographic characteristics of participants, 12 questions to estimate level of knowledge about COVID-19, six questions to evaluate attitudes toward disease, and three questions to assess practices to prevent disease transmission. RESULTS: Their overall understanding of COVID-19 was satisfactory. 69% of the participants had satisfactory levels of knowledge, and the main sources of information were social media platforms (79.70%) and television (70.90%). There was a significant difference in knowledge as a function of gender (p = 0.50), occupation (p = 0.012), and smoking (p = 0.041). The participants held optimistic attitudes and adopted appropriate protective measures. Most participants agreed that COVID-19 can cause death (64.7%), poses greater risks to elderly (93.4%) and those with chronic diseases (96.7%), it is mandatory to quarantine infected individuals (98.1%), preventive health measures are important (97.6%), and health authorities will succeed in controlling the pandemic (67.5%). There was a statistically significant association between satisfactory levels of knowledge and the practice of wearing masks and the adoption of protective measures (avoiding crowded places, frequent hand washing). CONCLUSIONS: Residents of Al-Jouf region in Saudi Arabia have satisfactory levels of knowledge, optimistic attitudes, and good practice during the rapid rise period of the pandemic. Awareness campaigns will improve any misbeliefs and risky behaviors.

Influence of irisin on diet-induced metabolic syndrome in experimental rat model.

OBJECTIVE: To evaluate the influence of irisin on the experimental paradigm of non-alcoholic fatty liver (NAFL) as a part of MetS cluster. METHODS: Forty male albino rats were divided into four groups; normal control, standard diet + irisin, high carbohydrate and fat diet (HCHF), and HCHF + irisin. After the experimental period, levels of fasting blood sugar (FBS), insulin, lipid profile, kidney functions, salusin-alpha (Sal-α), adropin, and retinol-binding protein-4 (RBP-4) were evaluated. Peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1α) expression in skeletal muscle was evaluated by quantitative real-time PCR. Aorta, liver, pancreas, and skeletal muscle tissue samples were prepared for histopathological examination. RESULTS: Rats administrated HCHF showed elevated levels of FBS, lipid profile, kidney functions, RBP-4, and downregulation of PGC-1α expression along with a decline in levels of insulin, Sal-α, and adropin while administration of irisin significantly attenuated these levels. CONCLUSIONS: Irisin as based therapy could emerge as a new line of treatment against MetS and its related diseases.

Perceived Barriers and Awareness of Mammography Screening Among Saudi Women Attending Primary Health Centers.

PURPOSE: Mammography screening (MS) is an underutilized screening tool; although it is provided free of charge to the Saudi community. The present study aimed at assessing knowledge and barriers of mammography screening among women attending primary health centers in Aljouf region, Saudi Arabia. MATERIALS AND METHODS: A cross-sectional study was carried out among 423 women aged 41-75 years attending ten primary health centers in Aljouf region, Saudi Arabia. Structured interviewing questionnaires were used for data collection. SPSS program, version 24 was used for data analysis. RESULTS: The least reported risk factors of BC in this study were early menarche (14.9%), first pregnancy after the age of 30 years (18%), and late menopause (18.7%). Concerning knowledge of MS, 50.8% of the women correctly identified that mammogram is the ideal method for detecting BC. The most encountered personal barriers towards MS were lack of information about mammogram (69.5%), fear of exposure to radiation (67.4%), fear of discovery of BC (62.9%), being busy all the time (62.2%), and fear of cancer treatment (61.9%). Regarding economic barriers, 40% of the participants reported that taking sick leave from work is difficult while 37.8% revealed that mammogram is costly. Concerning health system barriers, the most common barriers were fear of error in diagnosis (62.6%), long time to take medical appointment (57%), and preferring not to have a mammogram except after a doctor recommendation (52.7%). The present study showed that women's education and residence significantly predicted their knowledge. Furthermore, women's education and income significantly predicted their barriers towards MS. CONCLUSION: Many barriers toward mammography screening were encountered in the present study. Addressing these barriers and raising awareness about MS may be of great value to increase its uptake by Saudi women.
