Background/Objectives: The rational use of medicines, in accordance with the World Health Organization (WHO) guidelines, is crucial for optimizing healthcare outcomes. This cross-sectional study aimed to evaluate drug prescribing patterns and assess prescription completeness based on the WHO core drug use criteria. A comprehensive analysis was conducted at the University Clinic in the Northern region, Kingdom of Saudi Arabia (KSA). Methods: The study assessed drug prescribing patterns and examined prescription completeness by analyzing various parameters recommended by the WHO core drug use criteria. Results: Upon analyzing the 615 prescriptions, it was observed that each prescription had a mean of 2.56 prescribed drugs. Multiple medicines per prescription were prevalent in 71.4%, whereas polypharmacy was evident in 2.9%. Analgesics were the most frequently prescribed medication, accounting for 50.4% of the prescriptions, followed by supplements (31.7%), decongestants (16.1%), cough syrup (12%), and antihypertensive and diabetes treatments at 17%. Furthermore, antimicrobials were prescribed in 21.5% of the prescriptions. During the evaluation, it was found that 19.8% of the prescriptions were incomplete, lacking important information on dosing, duration, and drugs not suited to the diagnosis. Conclusions: Most of the parameters evaluated in this study were determined to fall outside the range of recommended guidelines criticized by the WHO. As a result, the implementation of efficient intervention programs, such as education initiatives, is recommended to enhance the practice of rational drug use. Contribution: This study highlights the importance of improving prescription indicators at the national level, focusing on both medication prescribing characteristics and prescription quality as a practice.

Background: Mental stress plagued type II diabetes (T2DM) patients. The psychological and emotional issues related to diabetes and its effects include depression, anxiety, poor diet, and hypoglycemia fear. Aim: Compare the impact of diabetes on depression and anxiety in Egyptian and Saudi diabetics. Methods: The diabetes, gastroenterology, and hepatology sections of University of Ha’il Clinic, KSA, and the Theodor Bilharz Research Institute, Egypt, conducted this retrospective study. Everyone gave informed consent before participating. Interviews with male and female outpatients and inpatients were conducted from June 2021 to December 2022. The self-administered validated Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) scale measured sociodemographic characteristics and symptoms of depression and anxiety. Results: In patients with diabetes, the prevalence of depression was higher in KSA [34.8%] than in Egypt [18%], while anxiety was higher in Egypt [40%] than in KSA [29.1%]. Most depressed patients were 31–55 years old (61.2%) from KSA and 97.8% (41–55 years old) from Egypt. Female anxiety was 70.7% in KSA and 51.0% in Egypt, with no significant difference. The duration of diabetes in depressed patients was 5–10 years ([46.9%, Saudis] vs. [57.8%, Egyptians]), while anxious patients (5–10 years [39.0%, Saudis] vs. >20 years [65.0%, Egyptians]) were mainly type-2. Most depressive patients had an HbA1c (59.2%) from 7–10% (Saudis) and 77.8% [>10% Egyptians] compared to anxiety patients (46.3%) and 48.0% [>10% Egyptians]. Depressed and anxious patients from both nations had higher glucose, triglycerides, and cholesterol levels. Saudis and Egyptians with obesity had higher rates of sadness (75.5% vs. 68.9%) and anxiety (82.9% vs. 69.0%). Treatment adherence and serum glucose monitoring were not significantly different from depression in diabetes individuals in both ethnicities. Conclusions: Anxiety was more common among Egyptian patients because of overcrowding, working whole days to fulfill life requirements, and the unavailability of health insurance to all citizens. Meanwhile, in KSA, obesity, unhealthy food, and less exercise reflect the high percentage of depression among patients with diabetes. The detection of depression and anxiety in the context of DM should be critical for the physical health and quality of life of Saudi and Egyptian diabetics. Further investigation is warranted to encompass anxiety and depression within the scope of future research.

Background: The risk of dying from chronic liver diseases (CLDs) is two to three times higher for patients with diabetes (DM). Nonalcoholic fatty liver disease (NAFLD) is the primary cause of this increased risk, which has an etiology unrelated to alcohol or viruses. Previous research reported that diabetes and CLD are related, since they influence each other. Aim: Estimation of the impact of diabetes (DM) on liver diseases (LD), and of the impact of liver diseases on DM among Egyptian and Saudi patients. It is a descriptive and prospective analytical study design. The investigation was carried out in Saudi Arabia and Egypt at gastroenterology outpatient clinics. Methods: Prospective data were collected through face-to-face patient interviews during clinic visits between June 2021 and June 2023. The interviews covered the patients’ basic characteristics and information on DM and LD. Certain laboratory tests were conducted on these patients, such as liver function, glucose level, lipid profile, INR, and prothrombin time. Results: The total of 2748 participants in this study included 1242 diabetic patients of both genders from Saudi Arabia and 1506 from Egypt. Most Saudis had between 10 and 20 years’ duration of DM (35.5%), with HbA1c (7–10%) values of 47.8%, while the Egyptian patients had >20 years’ duration of DM (39.8%), with HbA1c (7–10%) values of 49.8%. Regarding the impact of DM on the development of liver diseases, about 35.5% (Saudis) vs. 23.5% (Egyptians) had liver diseases due to DM, a significant difference (p-value = 0.011). Liver enzymes were increased in many of the Egyptian and Saudi patients (41.4% vs. 33%), while the presence of fatty liver (28.2% vs. 35.7%) and hepatocellular carcinoma (13.7% vs. 6.1%) were also significantly different (p-value = 0.047). While the impact of liver diseases on DM was observed more among Egyptian (59%) than among Saudi (46.4%) patients because of liver cirrhosis (HCV or HBV), known to be a reason for diabetes in Egyptians (27.9%) vs. Saudis (8.0%), a higher incidence of fatty liver leading to DM was observed in Saudis than in Egyptians (15.9% vs. 11.6%) (p-value = 0.000. Obesity was more prevalent among Saudi patients (63.8%) than among Egyptian patients (48.6%) (p-value = 0.019). Fewer Egyptians (about 65%) suffered from dyslipidemia than Saudis (about 80%). Higher INR and longer prothrombin times were observed in Egyptians (29.9% and 29.1%, respectively) than in Saudis (20.3% and 18.8%, respectively), with a significant difference between the two nations (p-value < 0.050). Conclusions: We may conclude that diabetes in most patients has a negative impact on the development of liver diseases (particularly fatty liver in Saudi patients). In addition, most liver diseases (liver cirrhosis) have a negative influence on the development of DM (more so in Egyptian patients). There is a link between DM and liver disease. In particular, liver cirrhosis and diabetes were found to influence each other. Therefore, correct medication, adherence to treatment, lifestyle modifications, successful cirrhosis control (in patients with liver diseases), and diabetic control (in diabetic patients) could lead to effective management of both diseases. The negative fallouts in the two cases were prompted by obesity, morbid eating, and poor quality of life.

Methicillin-resistant Staphylococcus aureus (MRSA) is a significant pathogen in both healthcare-associated (HA-MRSA) and community-associated (CA-MRSA) infections, posing major challenges due to its evolving antimicrobial resistance (AMR) and genetic diversity. This study investigates the prevalence, antimicrobial resistance patterns, and molecular characteristics of HA-MRSA and CA-MRSA isolates in Saudi Arabia. A retrospective analysis was conducted on 178 MRSA isolates obtained from clinical samples. MRSA identification was performed using cefoxitin disk diffusion, and antimicrobial susceptibility testing for vancomycin, linezolid, and ciprofloxacin was conducted using the BD Phoenix M50 system. Molecular characterization included SCCmec typing, spa typing, and PCR-based detection of virulence genes (pvl, tst, eta, etb, lukS, lukF). Statistical analysis was carried out using SPSS, with a significance threshold of p < 0.05. Among 1496 S. aureus isolates, 178 (11.9%) were confirmed as MRSA, with HA-MRSA (61.8%) being more prevalent than CA-MRSA (38.2%). Notably, 7.8% of HA-MRSA isolates exhibited heteroresistant vancomycin-intermediate S. aureus (hVISA). Ciprofloxacin resistance was significantly higher in HA-MRSA (85.0%) compared to CA-MRSA (38.9%). SCCmec type V was the predominant genotype (87.1%), suggesting increased infiltration of CA-MRSA strains into hospital settings. Spa typing revealed high genetic diversity, with t037 being the most common (27%). Virulence genes were detected in 6% of isolates, indicating limited dissemination of these factors. The findings highlight the increasing prevalence of MRSA, the emergence of hVISA, and shifts in clonal distribution, underscoring the need for ongoing molecular surveillance and stringent antimicrobial stewardship programs to control MRSA spread in both healthcare and community environments.

Methicillin-resistant Staphylococcus aureus (MRSA) is a devastating global health concern. Hypervirulent strains are on the rise, causing morbidities and mortalities worldwide. In tertiary care hospitals, critically ill patients, those undergoing invasive procedures, and pediatric and geriatric patients are at risk. It is not fully clear how strains adapt and specialize in humans and emerge despite the well-established commonality of the S. aureus genome from humans and animals. This study investigates the influence of age-, gender-, and source-specific profiles (clinical, intensive care unit (ICU vs. non-ICU)) on the evolution of hospital-associated (HA)-MRSA versus community-associated (CA)-MRSA lineages. A total of 253 non-duplicate S. aureus isolates were obtained from May 2023 to March 2025. The patients were stratified by age and gender in ICUs and non-ICUs. Standard microbiology methods and Clinical and Laboratory Standards Institute (CLSI) guidelines were used for identification and susceptibility testing, with cefoxitin and oxacillin disk diffusions and molecular diagnosis confirming MRSA. Mann–Whitney U and Chi-square tests assessed the demographic distributions, clinical specimen sources, and MRSA/methicillin-sensitive S. aureus (MSSA) prevalence. Of 253, 41.9% originated from ICUs (71% male; 29% female) and 58.1% from non-ICU wards (64% male; 36% female). In both settings, MRSA colonized the two extremes of age (10–29 and 70+) for males and females, with different mid-life peaks or declines by gender. However, the overall demographic distribution did not differ significantly between the ICU and non-ICU groups (p = 0.287). Respiratory specimens constituted 37% and had the highest MRSA rate (42%), followed by blood (24.5%) and wounds (10.3%). In contrast, MSSA dominated wounds (20.3%). Overall, 73.9% were resistant to cefoxitin and cefotaxime, whereas vancomycin, linezolid, daptomycin, and tigecycline remained highly effective. Younger non-ICU patients (10–29) had higher MSSA, whereas older ICU ones showed pronounced HA-MRSA profiles. By the virtue of methicillin resistance, all MRSA were classified as multidrug resistance. Thus, MRSA colonization of the two extremes of life mostly in ICU seniors and the dominance of invasive MSSA and CA-MRSA patterns in non-ICU youth imply early age- and gender-specific adaptations of the three lineages. MRSA colonizes both ICU and non-ICU populations at extremes of age and gender specifically. High β-lactam resistance underscores the importance of robust stewardship and age- and gender-specific targeting in screening. These findings also indicate host- and organ-specificity in the sequalae of MSSA, CA-MRSA, and HA-MRSA evolutionary dynamics, emphasizing the need for continued surveillance to mitigate MRSA transmission and optimize patient outcomes in tertiary care settings.
