RESUMO
Nutrition is an important aspect of a healthy lifestyle for all individuals, including adolescents. The objective of this cross-sectional descriptive survey study was to investigate university students' awareness of immunity enhancing foods, food nutritive values, and eating practices during the COVID-19 pandemic. A total of 839 university students from four different universities in Pakistan participated in the study from October 2021 to January 2022, 397 of which were male and 442 were female. A total of 419 students were studying in medical disciplines while 420 were non-medical students. The students had significant knowledge (p < 0.05) about COVID-19, and nutritional habits were seen in both medical and non-medical students. Results showed that medical students (n-201) were slightly more aware of immunity-enhancing foods and the nutritive values of foods compared to engineering students (n-79). However, eating practices were generally poorly adopted by all of the university students. Male and female students were not significantly different in their mean replies to questions on the nutritive value of food or in their eating habits. Healthy eating practices will aid university students in preventing illnesses connected to nutrition as well as enhancing their immune systems and nutritional well-being both during and post-pandemic. In light of these results, suggestions and implications for nutritional advice and education were explored.

Methicillin-resistant Staphylococcus aureus (MRSA) is accountable for a plethora of infections, ranging from minor cutaneous manifestations to grave metastatic conditions. The dissemination of MRSA among cancer patients poses a substantial public health hazard on a global scale. This study explores the association between MRSA and bacteriophage-encoded immune evasion cluster (IEC) genes. This investigation employed a total of 168 pathogenic MRSA collected from 38 cancer and 130 non-cancer patients. A cefoxitin disc diffusion method followed by PCR analysis was used to identify the mecA gene. In this study, we employed singleplex and multiplexed PCR techniques to detect specific IEC genes. No association (p = 0.98) was observed between the sex and age of patients and MRSA isolates. However, MRSA isolates demonstrated a notable association (p = 0.01) with pus samples in non-cancer patients and skin swabs in cancer patients. The resistance profiles of MRSA strains from cancer and non-cancer patients did not show significant differences (p > 0.05). Notably, the sea gene was found to be more prevalent in MRSA isolates from cancer patients, displaying a significant association (p = 0.03). Additionally, this study identified two novel and distinct combinations of IEC types, namely V1 (sea, chp, scn) and V2 (sea, scn). Cancer patients had higher multidrug resistance and toxin gene abundance than non-cancer patients. The identification of two novel IEC patterns underscores the urgent need to control MRSA dissemination in hospitals and monitor emerging clones.
RESUMO
Background: Diabetes-related vascular complications linked to increase in the expression of VEGF and its receptors. It helps to accelerate tissue damage inflicted by hyperglycemia, which is potential risk for diabetic complications. The study aimed to assess VEGF genetic polymorphism and its correlation with glucose and HbA1C level among Sudanese patients with diabetic retinopathy and nephropathy. Methods: A case-control study was conducted among a total of 252 subjects and divided into four groups of 63 subjects each. Glucose and HBA1c were measured then the VEGF gene was amplified using polymerase chain reaction. The data were analyzed using SPSS. Results: The HBA1c, and blood glucose levels had significantly (P value≤0.00001) highest mean in the DR group, DN group followed by DM. There is a non-significant correlation between VEGF Genotypes and HbA1c, and blood glucose levels (P value≤0.102, 0.173) Patients with GC genotypes will be 74.6%, and 54% higher at risk to develop DR, and DN respectively and 40 % lower at risk to develop DM than those without GC genotype. While patients with CC genotypes will be 22.2% higher at risk of developing DM and 9.5%, 12.2% higher at risk of developing DR and DN respectively. Discussion: The VEGF +405G/C gene polymorphism is linked to diabetic retinopathy, and diabetic nephropathy in type 2 Sudanese diabetics, and the presence of the GC genotypes and G allele is a significant predictor for retinopathy. There is no significant relation between HbA1C serum levels, blood glucose, and the VEGF +405G/C gene polymorphism.
RESUMO
<b>Background and Objective:</b> Viremia due to SARS-CoV-2 lead variety of biochemical change in the human body, which play a crucial role in the activation of the coagulation cascade causing thrombotic complications and coagulopathies. The study aimed<i> </i>to ascertain the D-dimer level as a biological mediator in COVID-19 patients in Khartoum state and compare the results to the control group. <b>Materials and Methods:</b> A cross-sectional study was conducted during the period of August to December, 2021, including 50 healthy patients and 50 COVID-19 patients, blood samples were collected from study groups for measurement of D-dimer level using an I Chroma device. Statistical analysis was conducted using SSPS version 21. <b>Results:</b> This study revealed a statistically increased D-dimer level among COVID-19 patients compared with the control group (2000-10000 vs. up to 500 ng mL<sup></sup><sup>1</sup>), respectively. <b>Conclusion:</b> Viremia induced by COVID-19 infection can cause a high D-dimer level which can lead to thrombosis event or bleeding tendency.

<b>Background and Objective:</b> Immune complexes and pro-inflammatory cytokines deduced from communicable diseases have been manifested to induce pro coagulopathy and tissue factor (TF) assertion in macrophages and the endothelial cells that remain at critical risk in tuberculosis (TB) patients. The current study was carried out among Sudanese patients with Pulmonary tuberculosis aimed to determine the long-term impacts of Tb infection on the coagulation cascade. <b>Materials and Methods:</b> A cross-sectional study was conducted among 30 patients who are already diagnosed with tuberculosis compared with the control group. Pulmonary Tuberculosis diagnosis of cases was emphasized in accordance with clinical examination, chest X-ray and positive Ziehl-Neelsen (ZN) smear. The questionnaire was used for the collection of demographic and baseline data. About 2.5 mL of venous blood was collected in trisodium citrate containers and 2.5 mL of blood was collected in EDTA container. SPSS version 21 statistical software was used for statistical analysis. <b>Results:</b> PLT count showed a significant difference (p = 0.03) with a mean (329.20×10<sup>3</sup> and 287.60×10<sup>3</sup> µL<sup></sup><sup>1</sup>) among patients and control, respectively. APPT shows a significant difference (p = 0.00), Mean of PLT decreased as the disease progressed (336.20±36.02, 345.43±16.02, 511.04±42.02) showed a significant correlation between PLT count of test and duration of disease (p = 0.00). Additionally, a significant correlation between PLT count, MPV and APTT and the status of the patient's drug resistance was revealed (p<u><</u>0.02, 0.01 and 0.02). <b>Conclusion:</b> There is a significant alteration in coagulation parameters (PT, APTT and platelets count) among Sudanese pulmonary tuberculosis patients, which may indicate a feature of a hypercoagulable state.

BACKGROUND AND OBJECTIVE: The pathophysiological mechanisms of irritable bowel syndrome are controversial and the exact mechanism that play role in exaggeration of symptoms is mysterious. As an altered immunological functions in IBS patients may play role to study pro and anti-inflammatory cytokines among the study population. The aim of this study is to examine the serum cytokines of IL 10 and INFγ profile among a group of IBS patients and control. MATERIALS AND METHODS: A cross sectional prospective study was conducted among 40 participants, who were referred to gastroenterology out patients clinics at Khartoum Teaching Hospital, Khartoum State, Sudan. Five milliliters blood were collected in EDTA tubes for measuring levels of cytokines in serum. Cytokines were measured by ELISA-MSD (Meso Scale Discovery). They were measured according to the manufacturer's instructions and expressed as pg mL-1. Optical density was measured at a wavelength of 450 nm and a reference wavelength of 590 nm. RESULTS: Out of 16 (40%) male and 24 (60%) female, their age group range between 20-70 years old. The majority of them 21(52.5%) in age group (31-50) years old. Overall IBS patients showed significantly increased (p = 0.0001) of INF-γ (29.50±17.98 vs. 6.9±1.724 pg mL-1) between patients and control, respectively. The serum levels of IL-10 was significantly higher in patients with IBS compared with control group (p = 0.001). CONCLUSION: There is an abnormal immune regulation, supporting the presence of immune activation in IBS.
