Tuberculosis (TB), one of the deadliest contagious diseases, is a major concern worldwide. Long-term treatment, a high pill burden, limited compliance, and strict administration schedules are all variables that contribute to the development of MDR and XDR tuberculosis patients. The rise of multidrug-resistant strains and a scarcity of anti-TB medications pose a threat to TB control in the future. As a result, a strong and effective system is required to overcome technological limitations and improve the efficacy of therapeutic medications, which is still a huge problem for pharmacological technology. Nanotechnology offers an interesting opportunity for accurate identification of mycobacterial strains and improved medication treatment possibilities for tuberculosis. Nano medicine in tuberculosis is an emerging research field that provides the possibility of efficient medication delivery using nanoparticles and a decrease in drug dosages and adverse effects to boost patient compliance with therapy and recovery. Due to their fascinating characteristics, this strategy is useful in overcoming the abnormalities associated with traditional therapy and leads to some optimization of the therapeutic impact. It also decreases the dosing frequency and eliminates the problem of low compliance. To develop modern diagnosis techniques, upgraded treatment, and possible prevention of tuberculosis, the nanoparticle-based tests have demonstrated considerable advances. The literature search was conducted using Scopus, PubMed, Google Scholar, and Elsevier databases only. This article examines the possibility of employing nanotechnology for TB diagnosis, nanotechnology-based medicine delivery systems, and prevention for the successful elimination of TB illnesses.

Background: Sexually transmitted diseases (STDs) remain one of the most important health challenges in not only developing countries but also developed countries. Discussing STDs in the Saudi society is considered taboo, as social factors and ethics give rise to many obstacles. This study evaluates the knowledge of STDs among young adult students enrolled in Albaha University. Methods: This research is a cross-sectional study involving 1902 young adult students registered at Albaha University. STDs knowledge scores (STDs-KSs) were calculated using a predesigned and validated STDs knowledge questionnaire with 27 items adapted from previously developed questionnaires. Results: The estimated overall mean of STDs-KS was 7.95 ± 4.29. Female participants showed a significantly higher mean of STDs-KS, compared to males (8.51 ± 4.14 vs. 7.32 ± 4.38, p < 0.0001). Participants registered in health sciences programs showed higher STDs-KS, compared to participants from arts and sciences programs (p < 0.0001). Conclusions: Evidence from this study suggests a lack of STDs knowledge among young adults. To promote STDs awareness among this population, more health educational programs should be included in school curricula at the late stages of secondary education.

The human malaria parasite Plasmodium falciparum is responsible for the majority of mortality and morbidity caused by malaria infection and differs from other human malaria species in the degree of accumulation of parasite-infected red blood cells in the microvasculature, known as cytoadherence or sequestration. In P. falciparum, cytoadherence is mediated by a protein called PfEMP1 which, due to its exposure to the host immune system, undergoes antigenic variation resulting in the expression of different PfEMP1 variants on the infected erythrocyte membrane. These PfEMP1s contain various combinations of adhesive domains, which allow for the differential engagement of a repertoire of endothelial receptors on the host microvasculature, with specific receptor usage associated with severe disease. We used a co-culture model of cytoadherence incubating human brain microvascular endothelial cells with erythrocytes infected with two parasite lines expressing different PfEMP1s that demonstrate different binding profiles to vascular endothelium. We determined the transcriptional profile of human brain microvascular endothelial cells (HBMEC) following different incubation periods with infected erythrocytes, identifying different transcriptional profiles of pathways previously found to be involved in the pathology of severe malaria, such as inflammation, apoptosis and barrier integrity, induced by the two PfEMP1 variants.

Background: Procoagulant microvesicles (MVs) are submicron membrane fragments released from activated cells and cells undergoing apoptosis. The procoagulant activity of MVs is enhanced in the presence of tissue factor (TF). MVs and TF are active mediators that induce pro-inflammatory response and prothrombotic tendency and have been linked to the severity of several disorders, including malaria infection. The current study aimed to measure the levels of circulating procoagulant MVs and TF-bearing MVs in malaria patients and correlate these levels with other hematological parameters and parasitemia. Materials and Methods: Levels of MVs and TF-bearing MVs in the plasma of children and adult patients infected with Plasmodium falciparum were measured alongside matched healthy controls. Results: Patients with Plasmodium falciparum infection had ~3.8 times MVs (p < 0.0001) and ~13.0 times TF-bearing MVs compared to the matched healthy controls. MVs showed inverse significant correlation with platelet count (p = 0.0055), hemoglobin (p = 0.0004) and parasitemia. Conclusion: Elevated levels of MVs and TF-bearing MVs could be useful biomarkers to evaluate the procoagulant activity, inflammatory response and parasitemia levels in malaria infection, aiding in better management of the disease.

Introduction: Breast cancer (BC) awareness and preventive practices are critical for the early detection and effective management of the disease. This study aimed to assess the level of BC awareness among women residing in Al Baha, Saudi Arabia. Methods: A cross-sectional study was conducted using the Breast Cancer Awareness Measure (BCAM) survey tool to evaluate BC awareness among female residents of Al Baha between June and July 2023. The sample was obtained through the snowball sampling technique. Results: A total of 1007 women participated in the study, with a mean age of 29 ± 10.9 years. Overall awareness of BC warning signs and risk factors was low, with 45% of participants demonstrating poor awareness. Significant positive associations were found between BC awareness and factors such as level of education (p = 0.020), employment status (p = 0.023), field of study for students (p < 0.0001), and average monthly family income (p = 0.001). Furthermore, 75% of participants rarely or never practiced breast self-examination, and only 37% of those invited to the Ministry of Health’s screening program had attended. Conclusions: The results highlight a significant lack of awareness and knowledge about BC among women in Al Baha. These findings underscore the urgent need for targeted educational initiatives and awareness campaigns to address this knowledge gap and promote preventive practices.

Background: Unmet need for contraception remains a persistent global reproductive health challenge. In Saudi Arabia, national estimates indicate moderate contraceptive uptake; however, region-specific data on awareness, accessibility, and utilization of family planning (FP) services remain limited, particularly in semi-rural settings such as Al-Baha. Objective: To evaluate awareness, access, and utilization of family planning and reproductive health services and to identify perceived barriers and sociodemographic determinants among adult women in Al-Baha, Saudi Arabia. Methods: A population-based cross-sectional study was conducted using a 23-item online questionnaire administered to female residents aged ≥18 years between December 2024 and February 2025 through convenience sampling. Descriptive statistics summarized participant characteristics and FP-related variables. Associations between categorical variables were assessed using chi-square ( χ ²) tests. Univariable and multivariable logistic regression analyses were performed to estimate crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Statistical significance was set at a two-sided p < 0.05. Ethical approval was obtained from the Deanship of Scientific Research, Al-Baha University (Approval No. 46110701–20241117), and electronic informed consent was secured prior to participation. Results: A total of 892 women participated (mean age 38 ± 10.5 years). Awareness of FP initiatives was reported by 24%, and 18% had previously received FP consultation/services. Although 94% reported geographic access to a healthcare facility within 30 min, routine reproductive health service utilization remained limited, with 53% reporting infrequent visits. Current contraceptive use was reported by 42%, predominantly oral contraceptive pills (15%) and intrauterine methods (9%). Overall, 32% reported at least one barrier to contraception access, with “other barriers” (14%) and limited availability (11%) cited most frequently. Several outcomes demonstrated significant sociodemographic variation ( p < 0.05). In multivariable analysis, age >30 years independently predicted current contraceptive use (aOR 3.97; 95% CI 2.64–5.98; p < 0.001). Conclusion: Despite reported geographic accessibility, awareness and counselling uptake remain suboptimal in Al-Baha. Targeted, culturally responsive primary care-based interventions and strengthened service availability are warranted to improve informed reproductive health decision-making.
