Awareness and prevalence of self-reported benign prostatic hyperplasia: a cross-sectional study in Saudi Arabia

BackgroundBenign prostatic hyperplasia (BPH) is a prevalent condition in older men, causing significant morbidity. Despite recent progress, essential concerns of the disease remain under-researched. This study aims to assess knowledge and estimate self-reported prevalence of BPH in Saudi Arabian men. Understanding BPH prevalence in Saudi Arabia is essential for healthcare planning, resource allocation, public awareness, early detection, intervention, research, and addressing regional variations.MethodA cross-sectional study was conducted from February to May 2022 using a validated questionnaire. Univariate and multivariate statistical methods assessed knowledge of BPH among 559 adult Saudi men (mean age: 47.2 years) and its association with demographic variables.ResultsThe self-reported prevalence rate of BPH for Saudi Arabian men was 12.0%. Most adults (74.2%) were aware that BPH is a risk factor for prostate cancer and 75% were aware of the increased risk of BPH in older people. Furthermore, 44.5% of participants associated nocturia with BPH, while 76.6% related urinary tract infection (UTI) with BPH. The study demonstrated a significant association between BPH awareness and marital status (p = 0.02), level of education (p = 0.02), and employment status (p = 0.04).ConclusionWhile men in Saudi Arabia generally had sufficient knowledge about BPH, there was a knowledge gap regarding certain risk factors like obesity and cardiac diseases. To address this, an educational program should be developed for both the general population and those at high risk of BPH

A comprehensive review on potential applications of metallic nanoparticles as antifungal therapies to combat human fungal diseases

Human pathogenic fungi are responsible for causing a range of infection types including mucosal, skin, and invasive infections. Life-threatening and invasive fungal infections (FIs) are responsible for mortality and morbidity, especially for individuals with compromised immune function. The number of currently available therapeutic agents against invasive FIs is limited compared to that against bacterial infections. In addition, the increased mortality and morbidity caused by FIs are linked to the limited number of available antifungal agents, antifungal resistance, and the increased toxicity of these agents. Currently available antifungal agents have several drawbacks in efficiency, efficacy, toxicity, activity spectrum, and selectivity. It has already been demonstrated with numerous metallic nanoparticles (MNPs) that these nanoparticles can serve as an effective and alternative solution as fungicidal agents. MNPs have great potential owing to their intrinsic antifungal properties and potential to deliver antifungal drugs. For instance, gold nanoparticles (AuNPs) have the capacity to disturb mitochondrial calcium homeostasis induced AuNP-mediated cell death in Candida albicans. In addition, both copper nanoparticles and copper oxide nanoparticles exerted significant suppressive properties against pathogenic fungi. Silver nanoparticles showed strong antifungal properties against numerous pathogenic fungi, such as Stachybotrys chartarum, Mortierella alpina, Chaetomium globosum, A. fumigatus, Cladosporium cladosporioides, Penicillium brevicompactum, Trichophyton rubrum, C. tropicalis, and C. albicans. Iron oxide nanoparticles showed potent antifungal activities against A. niger and P. chrysogenum. It has also been reported that zinc oxide nanoparticles can significantly inhibit fungal growth. These NPs have already exerted potent antifungal properties against a number of pathogenic fungal species including Candida, Aspergillus, Fusarium, and many others. Several strategies are currently used for the research and development of antifungal NPs including chemical modification of NPs and combination with the available drugs. This review has comprehensively presented the current and innovative antifungal approach using MNPs. Moreover, different types of MNPs, their physicochemical characteristics, and production techniques have been summarized in this review

Perspectives and Prospective on Solid Lipid Nanoparticles as Drug Delivery Systems

Combating multiple drug resistance necessitates the delivery of drug molecules at the cellular level. Novel drug delivery formulations have made it possible to improve the therapeutic effects of drugs and have opened up new possibilities for research. Solid lipid nanoparticles (SLNs), a class of colloidal drug carriers made of lipids, have emerged as potentially effective drug delivery systems. The use of SLNs is associated with numerous advantages such as low toxicity, high bioavailability of drugs, versatility in the incorporation of hydrophilic and lipophilic drugs, and the potential for production of large quantities of the carrier systems. The SLNs and nanostructured lipid carriers (NLCs) are the two most frequently used types of nanoparticles. These types of nanoparticles can be adjusted to deliver medications in specific dosages to specific tissues, while minimizing leakage and binding to non-target tissues

Community Pharmacists’ Perceptions of Their Role in Provision of Anemia Management in Jazan Region, Saudi Arabia, and the Associated Barriers

Background: As a result of the lack of research exploring community pharmacists’ perspectives on anemia care, this study examined the perceived practices and barriers to anemia management services in Saudi Arabia. Methods: A questionnaire was administered to community pharmacists to validate pharmacist perceptions of their role in anemia care. Using an 11-item role test, pharmacists were asked about their perceptions of anemia management. Pharmacy anemia management barriers were explored using 20 items, and their perceptions of inter-professional contact were examined by two items. Data analyses were performed using SPSS version 22. Results: This research involved 324 community pharmacists, 62.3% of whom were males. There were significant differences between the location of pharmacy education and the perceived practice of anemia management. The most common barriers to anemia counseling were patients’ lack of knowledge about anemia, health beliefs, patients’ perceptions that their doctor takes care of them, and time constraints. The majority of respondents said they would like to have more contact with other healthcare professionals regarding the care of anemia patients. Conclusions: A positive perception of pharmacists’ role in anemia management is prevalent among Saudi pharmacists in the Jazan region. Anemia management is challenging due to time limitations and patient-related problems

COVID-19 Vaccines and Restrictions: Concerns and Opinions among Individuals in Saudi Arabia

(1) Background: Recent studies in Saudi Arabia have indicated that a small proportion of the population is hesitant to receive COVID-19 vaccines due to uncertainty about their safety. The objective of this study was therefore to examine concerns about COVID-19 vaccines in Saudi Arabia; (2) Methods: This cross-sectional study surveyed Saudi residents aged 14 years and older. The online questionnaire consisted of the following sections: (1) demographics; (2) knowledge about COVID-19 vaccines and sources of information; (3) COVID-19 vaccines worry scale; and (4) opinions about restrictions placed on unvaccinated individuals in Saudi Arabia. An adjusted regression model was computed to examine the relationships between demographic factors and worry about COVID-19 vaccines. All analyses were stratified by age, with those aged 19 years and above considered adults and those aged younger than 19 years considered as adolescents; (3) Results: A total of 1002 respondents completed the survey. Of the study sample, 870 were aged ≥19 years and 132 were aged <19 years. Of the adults in the study sample, 52% either agreed or strongly agreed with the statement, “I am worried about the potential side effects of COVID-19 vaccinations in children”. Among adults, females demonstrated higher levels of worry about COVID-19 vaccines than males (β = 1.142; p = 0.004) in the adjusted analyses. A high percentage of the participants either disagreed or strongly disagreed with allowing unvaccinated individuals to enter malls, schools, universities or to live freely without restrictions; (4) Conclusions: A high proportion of individuals in Saudi Arabia are concerned about possible side effects of COVID-19 vaccines, and many believe that unvaccinated individuals should not be restricted from participating in public life. It is therefore crucial to provide easily accessible information on the safety of COVID-19 vaccines in order to accelerate vaccination and minimize hesitancy regarding any future vaccinations that may be necessary

Exploring patient’s perspective of barriers to diabetic medication adherence in Jazan, Saudi Arabia, using the social determinants of health model

Background: Type 2 diabetes mellitus is usually associated with long-term macrovascular and microvascular complications that negatively impact the patient’s quality of life and add economic burden to the healthcare system. Understanding patients’ perspectives on medication nonadherence is essential for planning the appropriate methods and strategies to improve medication adherence among patients with uncontrolled diabetes. Aim: Therefore, this study aims to explore patients’ perceptions of the barriers to medication adherence through the Social Health determinants framework. Method: After obtaining ethical approval, qualitative face-to-face interviews with a sample of patients with type 2 diabetes mellitus (uncontrolled diabetes) were conducted. Interviews were audio-recorded, and then the data were analyzed using thematic analysis to identify essential themes related to the patient’s views. Results: Fifteen patients with type 2 diabetes mellitus were interviewed. Potential barriers to antidiabetic medications were identified and categorized based on the Social Determinants of Health domains. The patient’s health perceptions and behaviors were found to positively or negatively impact medication adherence. Beliefs toward antidiabetic medications, polypharmacy, medication-related problems, and the relationship between patients and their healthcare providers that related to healthcare access and quality domains were also reported as potential barriers to medications. Financial constraints, social stigma, and family support were other social health determinants factors that were found to have either positive or negative impacts on adherence. Nevertheless, using mobile health applications was suggested to facilitate medication adherence. Conclusion: Social Determinants of Health, such as education about type 2 diabetes mellitus, quality and access to healthcare, and social stigma and support, might significantly affect medication adherence among type 2 diabetes mellitus patients. This study’s findings can aid the development of suitable patient-specific tools and strategies to enhance medication adherence

Design and characterization of Lactotransferrin peptide-loaded dextran-docosahexaenoic acid nanoparticles: an immune modulator for hepatic damage

Abstract The primary objective of this research was to create injectable delivery formulations using Lactotransferrin (LTF) peptide-loaded dextran nanoparticles coated with docosahexaenoic acid. These nanoparticles, designated as LLDDNP, underwent a lyophilization process. The study encompassed a comprehensive investigation, including physicochemical characterization, in vivo assessment of biomarkers, and an examination of immune response through cytokine modulation. The zeta potential of LLDDNP was − 24.5 ± 12 mV, while their average particle size was 334.9 z.d.nm. The particles exhibited a conductivity of 2.10 mS/cm, while their mobility in the injectable dosage form was measured at − 3.65 µm cm/Vs. The scanning electron microscopy investigation, the lyophilization processes resulted in discrete particles forming particle aggregations. However, transmission electron microscopy analysis revealed that LLDDNP is spherical and smooth. The thermogram showed that about 95% of LLDDNP's weight was lost at 270 °C, indicating that the particles are extremely thermal stable. The XRD analysis of LLDDNP exhibited clear and distinctive peaks at 2θ angles, specifically at 9.6°, 20.3°, 21.1°, 22°, 24.6°, 25.2°, 36°, and 44.08°, providing compelling evidence of the crystalline nature of the particles. According to proton NMR studies, the proton dimension fingerprint region of LLDDNP ranges from 1.00 to 1.03 ppm. The in vitro release of LTF from LLDDNP was found to follow zero-order kinetics, with a commendable R2 value of 0.942, indicating a consistent and predictable release pattern over time. The in vivo investigation revealed a significant impact of hepatotoxicity on the elevation of various cytokines, including IL-1β, IL-6, IL-8R, TNF-α, IL-2, IL-4, IL-10, and IFN-γ. Additionally, the presence of hepatotoxicity led to an increase in apoptosis markers, namely caspase 3 and caspase 9, as well as elevated levels of liver biomarkers such as CRP, ALP, ALT, and AST. In contrast, the treatment with LLDDNP modulated the levels of all biomarkers, including cytokines level in the treatment group extremely high significant at p < 0.001
