Background: Health care waste management constitutes one of major public health concerns of modern health care. Since the healthcare workers are at the forefront of the waste generation, their knowledge on its management and hazard prevention is a major determinant of safe handling practices and effective infection control. Methodology: Present study has been conducted as a cross-sectional study among a convenient sample of health care workers, in King Salman Hospital Riyadh (N=131), during July-August 2024. A self-administered questionnaire was used to collect the quantitative data, in both English and Arabic language. The questions were asked under three main domains of the waste management; segregation, transportation and hazard prevention. Result: Out of total 133 study participants, majority of our study participants were nursing staff (77%, 103/133), in the age group of 31-40 years (54%, 72/133) and been working at our hospital for 2-5 years (46%, 61/133). For the survey items, the positive responses ranged from 72%-98%, 81-96% and 81-100% among the segregation, transportation and hazard prevention domains respectively. Conclusion: We have observed a high level of knowledge and awareness regarding hazardous waste management among healthcare workers, reflecting the efforts taken for continuous capacity building.

Learning Needs Assessment (LNA) is a fundamental component of professional nursing development, especially in tertiary care settings where nurses require specialized clinical and non-clinical competencies. King Fahad Specialist Hospital–Dammam (KFSHD), a major tertiary center in Saudi Arabia, provides advanced services across oncology, transplant, neurosciences, medical, surgical, critical care, and emergency departments. Due to the complexity of these specialties, assessing nurses’ learning needs is essential for guiding targeted continuing education activities. Aim: This study aimed to identify nurses’ learning needs across four components of continuing education, determine preferred locations and durations for learning activities, identify preferred learning methods, examine perceived barriers, evaluate satisfaction with current programs, and compare results across different years of experience. Methods: A cross-sectional survey was conducted in a tertiary hospital across all different levels of nursing. Sample was collected using quota sampling across inpatient and outpatient nursing departments at KFSHD. An online questionnaire consists of six domains was distributed to all nurses, supported by automated reminders to enhance participation. Data were analyzed using SPSS 2024 through descriptive statistics, chi-square testing, and content analysis. Results: A total of 903 nurses participated. The highest reported learning needs were related to emergency response (40.5%), crash cart and defibrillator use (34.6%), and medication courses (29.3%). Most participants (74.3%) preferred continuing education activities lasting no longer than one day, and nearly half indicated a preference for session durations of 15–30 minutes. Lecture-based presentations were the most preferred learning method (47.2%), while work schedule conflicts were the primary barrier to attendance (42.3%). Experience-based differences were evident, with less experienced nurses up to 5 years expressing higher learning needs for medication-related courses, while nurses with more than 15 years of experience showed greater needs for documentation training. Additionally, nurses with mid-level experience of 6-10 years demonstrated increased interest in nursing informatics. Conclusion: Nurses at KFSHD value continuing education and benefit most from short, experience-tailored training sessions. Educators should adopt micro learning and create level-specific pathways focused on high-priority clinical skills. Administrators must address workload barriers by providing flexible learning time and ensuring programs align with learning needs and operational realities.

Necrotizing fasciitis or "flesh-eating disease," is a rare and serious infection that can kill a person in less than a day. Early diagnosis and appropriate treatment can avoid serious complications that can lead to death. Herein, we report three cases of necrotizing fasciitis of the hand admitted to the emergency department and detail their management, from the diagnosis to the outcome. Before causing death, necrotizing fasciitis causes massive destruction of the soft tissue and bones, even in early diagnosed patients. The diagnosis is challenging, even for orthopedic surgeons. Once it is suspected, "acting fast" is mandatory, and so the orthopedic surgeon should be alerted.

Background: Proper treatment of wounds is crucial, as untreated wounds can potentially become fatal. Ethnomedicinal herbs possess the ability to heal wounds without causing any adverse consequences, unlike chemical medications which are increasingly associated with negative effects. Hydrogels are highly promising and extensively employed in the realm of biomedicine. Hydrogel dressings have made tremendous advancements in their ability to reduce inflammation, effectively addressing many clinical problems encountered in efforts to enhance wound healing. Lupeol, a triterpene phytoconstituent, is present in numerous fruit plants and medicinal plants that have been extensively researched for its potential in treating various ailments, including skin wounds. Objective: The aim of present investigation is to assessed the wound healing efficacy of lupeol loaded hydrogel. Method: A hydrogel was synthesized by combining Carbopol 934 with HPMC polymers in a 1:1 ratio. The wound healing potential was assessed using both the excision and incision models, as well as by measuring the hydroxyproline content. Result: The excision wound study demonstrated that the H1 formulation including lupeol exhibited a substantial outcome that was comparable to the usual treatment. The duration of epithelization was determined to be 18 days. The incision wound model demonstrated that the tensile strength of H1 was much greater than the standard. The current study determined that the hydroxylproline content of formulation H1, which contains lupeol, was measured to be 43.52 +0.42, which is comparable to the standard. Conclusion: The exploration has demonstrated that the formulation has the ability to enhance the activity of wound healing. The discovery indicated that lupeol promotes the formation of new blood vessels, the expansion of fibroblast cells, and the production of cytokines and growth factors that are essential for the process of wound healing.

The current paper is a full statistical study of solar power generation and capacity utilisation using a huge sample (161,864 half-hourly observations) of the photovoltaic grid supply infrastructure in the United Kingdom. The primary goal is to analyse the dynamics in the production of solar energy and compare the effectiveness of using capacity under seasonal and diurnal variations. The information, acquired with the help of the Kaggle open-data platform, represents the data about the actual generation in megawatts (MW), the actual capacity, lower and upper confidence limits of the generation forecast, and the inferred data, such as the percentage of the capacity utilisation, and the range of the prediction interval. The statistical tests on descriptive statistics, Pearson correlation analysis, one-way analysis of variance (ANOVA) with a post hoc Tukey HSD, and multiple linear regression were done using IBM SPSS Statistics. The results show that the mean solar output varies significantly across the seasons, with the highest mean (M = 1959.49 MW, SD = 2362.23) and lowest (M = 492.23 MW, SD = 1057.79) in summer and winter, respectively. Diurnal analysis indicated the afternoon hours showed the highest generation (M = 2866.20 MW), and low generation in the night (M = 11.17 MW). The overall capacity utilisation was just 10.04, and this implies that the installed photovoltaic infrastructure was not well used. The outcomes present some practical information that may be utilised by grid operators, renewable energy planners and energy policymakers to utilise solar energy optimally in the national power systems.

Background: The Kingdom of Saudi Arabia has substantially expanded digital health services in recent years through eHealth platforms such as Sehaty and Wasfaty, aligning with the digital transformation pillar of Vision 2030. Despite this rapid expansion, the uptake of healthcare applications among older adults has remained uneven, with barriers reported in digital literacy, usability, and perceived benefit. Objective: This study aimed to examine the factors influencing older adults' awareness and utilization of healthcare applications and the perceived effect of these applications on quality of life in Jeddah City, Saudi Arabia. Methods: A cross-sectional quantitative design was adopted. Data were collected in Jeddah City through an electronic questionnaire distributed in June 2025. The target population consisted of Saudi adults aged 30 years and above. A stratified random sampling technique was used based on age, gender, and education level. Out of 316 distributed questionnaires, 227 were returned (71.8% response rate) and 161 valid responses were retained for analysis. A structured Arabic-language questionnaire comprising four sections was developed and pilot-tested. Data were analyzed using SPSS Version 26, including descriptive statistics, chi-square tests, t-tests, one-way ANOVA, Pearson and Spearman correlations, and multiple linear regression, with statistical significance set at p < 0.05. Cronbach's alpha coefficients ranged from 0.875 to 0.944 across the subscales, with an overall alpha of 0.889 for the 39-item instrument. Results: The final sample (n = 161) was predominantly female (74.5%), aged between 30 and 40 years (60.9%), held a bachelor's degree (62.7%), and was married (81.4%). Awareness of healthcare applications differed significantly by gender, age, education, job title, occupation, and marital status (all p < 0.001). The strongest positive correlates of awareness and utilization were perceived benefit (r = 0.831), perceived ease of use (r = 0.681), and health and ageing issues (r = 0.658). The multiple regression model was significant, R² = 0.727, F(6, 156) = 69.26, p < 0.001. Perceived benefit (β = 0.606, p < 0.001) was the strongest predictor, followed by perceived ease of use (β = 0.193, p = 0.002) and health and ageing issues (β = 0.146, p = 0.013). Conclusion: Perceived benefit and perceived ease of use emerged as the key drivers of older adults' awareness and utilization of healthcare applications in Jeddah City. User-friendly design and clear communication of tangible value are therefore essential to maximize adoption and enhance the quality of life of this growing population.

The objective of this study was to assess the evolution of viral load on Tenofovir (TDF)+Lamivudine (3TC) +Dolutegravir (DTG) (TLD) in PLVAs newly initiated on ART. The study took place at the Psycho Medico-Social Support Center (APMS) in N’Djamena over a period of 12 months. Sociodemographic data and viral load (VL) data were collected using a pre-established form. The VC examination was performed using the BIOCENTRIC molecular biology platform. A total of 120 patients were included in this study. Analyses showed a highly significant decrease in CVs during TLD follow-up (p < 0.0001). The proportion of patients with a suppressed viral load (CV <1000 copies/m) was 20,8% at M0, 98.3% at M3, 93.3% at M6 and 95% at M12. These results show that the Dolutegravir-based therapeutic line is remains an essential pillar in HIV ART.
