Aims A family history of obesity, physical inactivity, and an unhealthy lifestyle was associated with an increased risk of diabetes in young individuals. Most published studies had focused on single risk factors such as BMI, Physical activity, and dietary lifestyle, while the combined effect and existence of those factors were largely neglected.
Methods This was a cross-sectional study conducted on 666 male students. Based on their family history of diabetes, their anthropometric measurements were also taken, and their BMI was calculated and categorised based on WHO standards.
Findings The results showed a significant correlation between obesity, family history, and diabetes, with a significant correlation between diabetes and obesity and also had a high positive correlation. While remaining correlations were also significant.
Conclusion The study concluded that a high proportion of students are at risk of diabetes and recommended an integrated intervention program to encourage healthy eating habits and physical activity and improve awareness.

Background: This study aimed to assess the relationship between cycle threshold (Ct) values and disease severity, symptoms, and comorbidities in COVID-19-positive individuals.
 Materials & Methods: This cross-sectional study was conducted on COVID-19 patients who were admitted to General Ghadamis hospital and diagnosed with COVID-19 from August 2020 to 2021. The association between Ct values and symptoms, demographic characteristics, and clinical characteristics was analyzed by SPSS analysis.
Findings: A total of 286 patients were included in this study, of whom 53.5% were female, and 46.5% were male, with a median age of 53 years (range: 1–90 years). Among symptomatic individuals, 51.4% had severe COVID-19 symptoms, and 26.6% had mild symptoms. Severe systemic symptoms were significantly associated with older age groups. The majority of elderly patients (66%) exhibited low Ct values (Ct ≤ 24), indicating a high viral load. Additionally, 64.6 and 40.8% of patients with severe and mild symptoms had low Ct values. Symptoms varied significantly across patients with low, medium, and high Ct values. There was a strong correlation between lower Ct values and the presence of comorbidities such as hypertension, diabetes mellitus, ischemic heart disease (IHD), cerebrovascular accident, and cancer.
Conclusion: Compared to asymptomatic individuals, most symptomatic patients with severe and mild symptoms had significantly lower Ct values. These findings highlight the critical role of viral load in SARS-CoV-2 progression and suggest that Ct values could be used to predict the spread of infection in the community.

This research studies pass numbers effect on microstructure and mechanical properties of magnesium alloy of AZ31C in the tubular channel angular pressing (TCAP) at the temperature of 300 °C. Pressing process has been carried out through four pass over AZ31C Magnesium tubes and in each pass the sample is exposed to Tensile and microhardness test and Metallography. The microstructure and mechanical properties of processed tube through one to four passes of TCAP process were investigated. Microhardness of the processed tube was increased to 62Hv after one pass from an initial value of 55 Hv. An increase in the number of passes from 1 to higher number of passes has not more effect on the microhardness. Yield and ultimate strengths were increased 1.97 and 1.49 times compared to as cast condition. Notably increase in the strength was achieved after two pass TCAP while higher number of passes has not more effect. Microstructural investigation shows notably decrease in the grain size to around 6 µm from the primary value of ~200 µm. microscope images show that the grain size is getting smaller by the first pass buy bigger in the next passes.
