Aquatic ecosystems and sediments are impacted by pollutants that enter water bodies through municipal wastewater, industrial effluents, and agricultural runoff. Bioaccumulation and biomagnification result from the accumulation of heavy metals, herbicides, and industrial pollutants in sediments. Carcinogenic, neurotoxic, and reproductive effects are caused by human exposure by ingesting, inhalation, and skin contact. Eight samples were taken from four significant locations in the Gulf of Tobruk to assess the level of pollution in the area: four surface water samples and four sediment samples. Specific of the heavy metals, including Fe, Mn, Zn, Ni, Pb, and Cd, had their concentrations measured. The results showed that Zinc, iron, and cadmium levels in water were high, and all heavy elements—Fe, Mn, Zn, Ni, Pb, and Cd—were above the WHO allowable limit in both surface water and sediments. This provides an indication that the Gulf of Tobruk is totally contaminated, unsuitable for a variety of activity uses, and hazardous to human health.

Makhlouf, Fatima Mohamed; Abdallah, Intisar H Cupping is an olden method that is at this time used as an alternative treatment for a wide variety of medical conditions. It has traditionally been used in various cultures and popular treatment in Arab and Islamic countries to relieve pain, removing toxins, and improving blood circulation. This study aimed to evaluate the effectiveness of wet cupping and to confirm its role in positively affecting patients with hypertension in some of their blood parameters. 18 samples of patients with hypertension, aged between 21-62 years (10 males and 8 females) who visited the Modern Medical Cupping Center in Sirte were used in this study. Samples were collected from December 23, 2023, to January 25, 2024. Blood samples were collected from the veins of patients before and after cupping (10 days after the cupping). Two blood samples were collected from each patient, and serum samples were tested for blood parameters and biochemical indicators, including hemoglobin (HGB), red blood cells (RBCs), white blood cells (WBCs), platelets (PLT), creatinine (CREA), urea (BU), triglycerides (TG), blood glucose (BG) and cholesterol (CHOL). Additionally, blood pressure measurements were also taken before and after cupping. The results presented a decrease in both blood systolic and diastolic pressure after cupping in both males and females, with statistical significance observed in males. There was a significant decrease in urea, cholesterol, triglyceride, and blood sugar levels in male patients after cupping (P>0.05), but an increase in platelet count after cupping. In female patients, cholesterol and blood sugar levels also decreased compared to pre-cupping values, with a higher MID% observed after cupping. In brief, cupping can be considered an alternative treatment method to medications through its role in regulating blood pressure and glucose levels, thus reducing the risk of heart and arterial diseases..

This study aims to assess the contemporary distribution of uropathogens and their antimicrobial resistance patterns among patients in Tobruk, Libya. A total of 200 urine samples were collected from symptomatic patients in 2021 at Al-Shifa Medical Center. The findings indicate that Staphylococcus aureus (33.6%) was the predominant isolate, followed by Escherichia coli (31.5%) and Klebsiella spp. (26.2%). This deviates from the global norm, where E. coli is typically dominant. Females were significantly more affected (82.1%) than males (17.9%), and high infection rates were observed among children, young adults, and the elderly. These trends underscore the importance of regional surveillance, evidence-based antibiotic policies, and targeted public health strategies to manage UTIs effectively. Keywords: Urinary tract infections, Staphylococcus aureus, Escherichia coli, Klebsiella spp., epidemiology, antimicrobial resistance, Tobruk, Libya. Objectives- To identify the most frequently isolated bacterial species responsible for UTIs in Tobruk, Libya.- To analyze the distribution of UTI cases by gender and age group.- To evaluate the antimicrobial susceptibility profiles of the isolated pathogens.

This study aimed to determine the clinical symptoms, laboratory test results, risk factors, and etiology of symptomatic UTIs in pediatric patients admitted to Tobruk Medical Center, with a focus on age and sex differences. The study was designed as a retrospective analysis and included data from 1 January to 31 December 2023. A total of 84 patients were included in the study. In terms of sex distribution, females were three times more prevalent than males, accounting for 77.4% of cases compared to 22.6% for males. The observed clinical presentations were as follows: dysuria (18%), suprapubic pain (17.2%), vomiting (17.2%), fever (15.2%), urinary frequency (15.2%), urgency (9.3%), and hematuria (7.8%). The age distribution of participants was as follows: 46% were between 3 and 4 years old, 40% were between 5 and 8 years old, 9.5% were between 9 and 12 years old, and 3.6% were over 12 years old.
