RESUMO
Background: The liver is crucial for maintaining normal metabolism in the body. Various substances, such as toxic chemicals, drugs, and alcohol, can damage hepatocyte cells, leading to metabolic imbalances. Aim: The experiment aimed to determine the efficacy of Lagenaria siceraria seed oil (LSS) as a hepatoprotective agent against acute hepatotoxicity triggered by carbon tetrachloride (CCl4). Methods: A total of 20 rats were randomly separated into four groups. The control group: rats received 2 ml of distilled water orally, followed by 1.25 ml of olive oil intraperitoneally (i.p.) after 30 minutes. CCL4 group: rats were given a single intraperitoneal dose of 1.25 ml/kg b.w. of CCl4 in a 1:1 mixture with olive oil. Silymarin group: received 100 mg of silymarin per kg of b.w. diluted in 2 ml of distilled water orally, followed by CCl4 treatment after 30 minutes. LSS oil group: received LSS oil at 3g/kg b.w. orally, followed by CCl4 treatment after 30 minutes. Blood samples were collected to assess liver enzymes (AST, ALT, and ALP), proteins and bilirubin fractions, and redox status (catalase, reduced glutathione (GSH), and malondialdehyde (MDA)) were assessed in hepatic tissues. Changes in liver histopathological examination were also evaluated. Results: In CCl4-treated rats, there was a significant increase in serum liver marker enzyme activity (ALP, AST, and ALT) along with a significant elevation (p < 0.05) in total bilirubin, indirect bilirubin, and direct bilirubin compared to the control rats. However, all these parameters decreased in the CCl4+ Silymarin and CCl4+LSS groups compared to CCl4-treated rats. There was a significant decline in total protein level and serum albumin in all experimental groups compared to the control, while globulin levels significantly increased in all experimental groups. There was a significant (p < 0.05) reduction in the level of GSH and catalase, with an increase in MDA level in CCl4 rats compared to other rats. Histopathological investigation of the LSS-treated group showed a hepatoprotective effect against CCl4. Conclusion: The study revealed that LSS oil has antioxidant activity against CCl4-induced toxicity.

The hazard of diseases created by S. Enteritidis and S. Typhimurium is relatively high in turkey meat products. Combinations of preservation methods are utilized in many strategies, such as mild heat with decreased water activity, a changed atmosphere, refrigerated storage, and decreased heat treatment with some acidification. Within the domain of ready-to-eat food technology, a range of preservation methods are typically utilized to enhance shelf life, such as applying mild heat in tandem with reduced water activity, employing modified atmosphere packaging, utilizing refrigerated storage, and utilizing reduced heat treatment combined with acidification. This investigation aimed to determine how S. Enteritidis and S. Typhimurium grew when sliced ready-to-eat smoked turkey (RTE-SM) was stored at 0, 5, 10, and 15°C for various periods. The study also examined the effects of modified atmosphere packaging (MAP) (40% CO2 and 60% N2) and VP on these growth patterns. Total viable count (TVC), lactic acid bacteria (LAB), pH, and redox potential levels were determined. The control experiment on RTE-SM showed no Salmonella growth within 30 d of storage at any temperature. This indicated that the RTE-SM in use did not initially contain S. Typhimurium and S. Enteritidis. Results indicated that the storage of RTE-SM using a combination of VP, MAP, and MAPEO with storage at 0 and 5°C did not allow for the pathogen to grow throughout storage. In comparison, at 10 and 15°C after one day, which allowed for minor growth (0.17-0.5 log CFU/g)? In contrast, at 0 and 5°C, Salmonella survives until the end of storage (173 d). However, the combination of MAPEO with the same storage temperatures achieved the elimination of the pathogen in the meat after 80 d. The combination of both packaging systems with high temperatures (10 or 15°C) allowed for the multiplication and growth of the bacterium through the product's shelf life of more than 1 log CFU/g. Thus, a combination of MAP or MAPEO with low storage temperatures (0 or 5°C) inhibited the growth of the pathogen.

Weight loss is a significant health problem among patients with head and neck cancer (HNC) that is attributable primarily to the tumor or tumor therapy. Critical weight loss (CWL) is defined as the unintentional loss of ≥5% of weight. Therefore, this study's goal was to investigate and determine the possible factors influencing CWL among patients with HNC who have received radiotherapy or concurrent chemoradiotherapy (CCRT). We conducted a retrospective analysis of 175 patients who received radiotherapy or CCRT as either their primary, adjuvant, or combined treatment at the Oncology Center in King Abdullah Medical City. All patients were ≥18 years of age and diagnosed with HNC with no metastasis. The study results showed that 107 patients (61%) had CWL, while 68 (39%) did not. The following factors were significantly predictive of CWL with a multivariate regression analysis: pretreatment BMI (AOR = 1.1, 95% CI = 1.02-1.17), oral cavity cancer (AOR = 10.36, 95% CI = 1.13-94.55), and male sex (AOR = 3.15, 95% CI = 1.39-7.11). In conclusion, weight loss is highly prevalent among HNC patients during treatment. Accordingly, pretreatment BMI, cancer in the oral cavity, and being male can be considered predictive factors for CWL.
RESUMO
This study aimed to determine the influence of dietary mannan-oligosaccharides (MOS) on the immune system, hematological traits, blood biochemical parameters, and histological state of laying hens. At 34 wk of age, The Mandarah chicken strain's 120 laying hens and 12 cocks were divided into 4 groups, each with 30 hens and 3 cocks. The first group performed as a control group, which nourished on a basal diet. The second, third, and fourth experimental groups received 0.1, 0.2, and 0.5 g/kg of MOS and a base diet, respectively. Birds obtained MOS at numerous doses significantly (P Ë 0.05) raised serum levels of immunoglobulin Y (IgY), immunoglobulin M (IgM), and avian influenza (AI) antibodies compared to control birds. Furthermore, adding MOS at a level of 0.1 g/kg diet significantly improved the immune response of the control group. Additionally, compared to the control group, treated birds with MOS at various dosages did not significantly enhance hematological parameters such as red blood cells (RBCs), white blood cells (WBCs), hemoglobin, and hematocrit. Compared to control birds, birds fed MOS at all levels exhibited considerably lower serum cholesterol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values. Also, compared to other treated birds, MOS-treated birds displayed improved histological examination of the small intestine, isthmus, and testis compared to the control group, particularly in birds fed MOS at 0.1 and 0.2 g/kg diet. It could be concluded that using MOS at 0.1 or 2 g/kg diet can successfully improve the physiological performance and overall health of laying hens.
RESUMO
Background and Objectives: People frequently utilize dietary supplements (DS), notably during the COVID-19 epidemic, despite the lack of data supporting their usefulness and safety in enhancing general health. This study aimed to measure the consumption of DS in Saudi Arabia during COVID-19. Previous studies focused on using dietary supplements for preventing or reducing mental health. Materials and Methods: A cross-sectional study was conducted with 1572 participants aged 18-65, from all-over Saudi Arabia who were invited to complete a self-administered questionnaire to measure the consumption of supplements during the pandemic lockdown period. Also, it investigates the factor that effect supplements consumption. Results: Around 63% of the participants did not change their consumption patterns during the pandemic, while 16% consumed more and 21.4% consumed fewer supplements during the pandemic. The most commonly used supplements were iron; calcium, especially among pregnant women; omega-3, especially in people older than 65 years; and vitamin D. Females (81%; P < 0.002); age (94.7%; P < 0.002); married people (84%; P < 0.001); those with a higher educational level (83.9%; P = 0.02); those with a higher monthly income (86.1%; P = 0.006); and pregnant women (100%; P < 0.007) reported the highest rates of consumption. Conclusion: Dietary supplements have recently become popular in Saudi Arabia, but large differences remain between Saudis in their consumption of supplements. Additional research should be conducted to examine the level of knowledge of dietary supplements among Saudi population.
RESUMO
Bariatric surgery (BS) is associated with vitamin and mineral deficiencies, which might be augmented by low adherence to dietary guidelines and inappropriate dietary behaviours. The aim of this study was to determine the influence of BS on eating behaviour, prevalence of nutrient deficiency, level of commitment to diet, and lifestyle recommendations one-year post-BS. A cross-sectional study was conducted among adult patients who underwent BS in 2019 and had follow-up for a year. Age, gender, and clinical data were collected from the hospital system and other information was obtained from questionnaires during phone interviews. A total of 160 patients participated in the study. At 12 months, a significant increase from the baseline values in plasma levels of vitamin B12, folate, vitamin D, iron, corrected calcium, albumin, CRP, and MCV, as well as a significant decrease in BMI was observed. Adherence to dietary and lifestyle recommendations was moderate to high. Emotional, and restrained eating behaviours were moderate with 64.4%, and 77.5%, respectively. External eating was low at 58.1%. The study concluded that pre-and post-bariatric surgery nutrients should be closely monitored.
RESUMO
BACKGROUND: In recent years, there has been great interest in the dietary practices of vegetarians in addition to an increasing awareness of the potential benefits of vegetarian diets. However, there are insufficient data on the spread of vegetarianism in Arab countries. The aim of this study was to investigate knowledge and attitudes about vegetarianism and associated factors in the Saudi population and to understand the reasons for its growing prevalence. METHOD: This is a cross-sectional study began in May 2020 and ended in September 2020. Researchers distributed the questionnaire electronically through social media. Data were collected electronically and exported to Excel by the researchers .The electronic questionnaire comprised three sections: sociodemographic questions, reasons for following a vegetarian diet, and beliefs and knowledge about vegetarianism. RESULTS: There were 3,035 responses, of which 80.2% of respondents were female and 19.8% were male. Participant were aged 18-65. Vegetarians represented 37.5% (15.7% semivegetarians, 8.1% pescovegetarians, 64.3% lacto-ovo-vegetarians, and 11.3% vegans), and the rest were nonvegetarians. The majority of the vegetarian participants (92.9%) had a low vegetarianism knowledge level. Health issues, followed by ethical and environmental concerns, were the most common motivators for adopting a vegetarian diet; these reasons were cited by 72.5%, 59.3%, and 47.9% of participants, respectively. Factors associated with increased vegetarianism were engaging in exercise for half an hour to two hours, while factors associated with decreased vegetarianism were male, aged 51-64 years, being married, having a higher education, working in the health sector, being a housewife, and having an income between 5,000 and 10,000 SR/month. CONCLUSION: Vegetarianism appears to be a growing phenomenon among the Saudi population. Increased awareness of health issues and the desire to live a healthy lifestyle might be the strongest motives. This study offers an opportunity to better understand vegetarianism in Saudi Arabia along with the possibility of expanding vegetarian food choices for the general public.

BACKGROUND: Refeeding syndrome (RFS) is a lethal condition of metabolic disturbances that arise from the sudden switch of metabolism from a state of starvation to one of nourishment. Quick recognition would reduce health complications. Physicians who are unaware of the syndrome will not identify and treat it. As nutritional risk is associated with the risk of RFS, physicians should be aware of it. AIM: To determine whether the physicians of King Abdullah Medical City (KAMC) in Makkah know of RFS and, if so, have skills in diagnosis and managing the syndrome. METHODS: One hundred and fifty-nine physicians of KAMC were recruited in a cross-sectional study. They were asked to complete a questionnaire by face-to-face interview. The questionnaire was designed to capture physicians' knowledge and ability to manage RFS based on the awarding of certain scoring points. RESULTS: The level of knowledge among physicians had a significant association between knowledge and age (p = 0.021) and medical specialty (p = 0.010). Additionally, the most knowledgeable physicians were those who work in critical care (21.4%). Around 18% of physicians were not able to manage RFS. CONCLUSIONS: Lacking knowledge of RFS and how to manage it leads to critical life-threatening complications. Physicians need nutritional education to help them diagnose RFS and consult dietitians to avoid its complications.
