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.

Assessment of community pharmacists' knowledge, attitudes and their willingness to provide vaccination services in Saudi Arabia.

BACKGROUND: Community pharmacists play an important role in increasing vaccination rates especially in countries where they offer vaccination services and administration. However, little is known about community pharmacist's willingness to provide vaccination services in Saudi Arabia. The objective of this study was to assess knowledge, attitudes, willingness and beliefs of community pharmacists in Saudi Arabia towards providing vaccines at pharmacies. METHODS: A cross-sectional, online questionnaire-based study using convenience sampling (Snowball technique) was used to obtain responses from community pharmacists across Saudi Arabia. The survey collected information on participants' demographics, knowledge about vaccine, attitude towards vaccine and their attitude to be immunization providers. Bivariate analysis and multiple linear regression models were employed to assess the relationships between demographic variables and outcomes. RESULTS: The study sample consisted of 384 community pharmacists. More than half of participants had poor knowledge about vaccines (54%). Only 8.4% of participants had good knowledge about vaccines. The results indicated that community pharmacists in the study sample have positive attitude toward vaccines and are willing to provide vaccination services. There was a significant relationship between knowledge about vaccine and attitude toward vaccines. Pharmacists with poor knowledge about vaccines had negative attitude toward vaccines as compared to those with high knowledge (ß = -1.743; P-value = 0.024). Additionally, there was a significant relationship between knowledge about vaccine and attitude to be immunization providers. Pharmacists with poor knowledge about vaccines had negative attitude to be immunization providers as compared to those with high knowledge (ß = -2.631; P-value = 0.002). Furthermore, a significant number of the community pharmacists reported facing critical barriers to provide vaccines including legal liability, lack of personal resources and lack of appropriate training. CONCLUSION: Comprehensive training and certification programs for pharmacists are crucial to improve their competencies in handling and administering vaccines to increase the rate of vaccinations in Saudi Arabia.

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

Background: Benign 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. Method: A 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. Results: The 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). Conclusion: While 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.

Hexaconazole exposure may lead to Parkinson via disrupting glucocerebrosidase and parkin: molecular interaction, dynamics, MMPBSA and DFT based in-silico predictive toxicology.

Hexaconazole is a known fungicide for agricultural purposes. It has bioaccumulation ability which makes it important for its toxicological characterization. There are various neurological impacts of pollutants on human health. Therefore, in this study, we have done predictive analyses of the interaction mechanism of hexaconazole by molecular interaction analysis, molecular dynamics simulation, and Poisson-Boltzmann surface area (MM-PBSA) to assess hexaconazole's potency to disrupt the homeostasis of glucocerebrosidase (-7.9 kcal/mol) and parkin (-5.67 kcal/mol) proteins which have significant roles in the manifestation of Parkinson disease. The findings reveal that hexaconazole has the potency to form stable interactions with glucocerebrosidase and parkin. This research provides a molecular and atomic-level understanding of how hexaconazole exposure may disrupt the homeostasis of glucocerebrosidase and parkin. The root mean square deviation (RMSD), root mean square fluctuation (RMSF), radius of gyration, and hydrogen bonding exhibited the potent molecular interactions of hexaconazole, which may lead to neurological manifestations such as Parkinson disease.

Exploring the knowledge, perception, and practice of community pharmacists in Saudi Arabia toward pharmacovigilance and adverse drug reaction reporting. A nationwide survey.

One of the significant worldwide health problems associated with pharmacovigilance is the under-reporting of adverse drug reactions (ADRs). Reporting suspected ADRs is essential to ensure patient safety, medicine safety, and healthcare quality. The new policy in Saudi Arabia emphasizes pharmacists taking a new clinical role, which may facilitate and improve the documentation of ADRs. Therefore, this study aimed to assess the knowledge and perception of community pharmacists towards the ADRs and their reporting practice in Saudi Arabia. A cross-sectional study using a structured self-administered questionnaire was administered to community pharmacists working in Saudi Arabia. Data were analyzed using descriptive and inferential statistics to identify the association between perceptions and ADR reporting practices. A P value < of 0.05 was considered statistically significant. A response rate of 43% (n = 163) was achieved, of whom 55.2% demonstrated knowledge of PV. Only 16% of community pharmacists were aware of the responsible center for monitoring and collecting ADRs in Saudi Arabia. The key facilitator was offering incentives to pharmacists, and the lack of time was found to be a key barrier among reporter community pharmacists. Positive attitudes toward pharmacovigilance and ADR reporting were expressed by community pharmacists. The findings of this study emphasize the further need for education and training programs and simplifying the ADR reporting process used in Saudi Arabia to enhance the reporting practice.

Zerumbone reduces TLR2 stimulation-induced M1 macrophage polarization pattern via upregulation of Nrf-2 expression in murine macrophages.

Hyperuricemia contributes significantly to gout arthritis pathogenesis, which promotes urate crystal deposition in the joints and activates joint-resident macrophages and circulating monocytes to initiate a state of inflammatory arthritis. In the joint, macrophages have an immune defense role where the presence of urate crystals results in the inflammatory mediators secretion, inflammatory cells recruitment to the joint, and shift macrophage population toward M1 pro-inflammatory phenotypes. Current treatment modalities of gout arthritis have side effects that limit their use in the elderly. A novel treatment that targets macrophage polarization to re-establish homeostasis may initiate a drug discovery program of novel disease-modifying agents for gout. Zerumbone (Zer) is a sesquiterpenoid bioactive compound found in the rhizome of Zingiberaceae family and possesses anti-inflammatory, antioxidant, and anti-proliferative activity. Our study hypothesized that soluble uric acid (sUA) and Pam3CSK4 (TLR2 agonist) reduce the anti-inflammatory function of murine M2 bone marrow-derived macrophages and change the expression of M2 genetic markers toward M1 phenotypes. We observed that priming of M2 macrophages with sUA and Pam3CSK4 significantly decreased M2 specific markers expression, e.g., Arg-1, Ym-1, and Fizz-1, enhanced mRNA expression of IL-1ß, TNF-α, CXCL2, and iNOS and increased oxidative stress in M2 macrophages, as exhibited by a reduction in Nrf2 expression. We also aimed to study the impact of Zer on reducing the pro-inflammatory effect of sUA in TLR2-stimulated M2 macrophages. We noticed that Zer treatment significantly reduced L-1ß and TNF-α production following Pam3CSK4 + sUA treatment on M2 macrophages. Furthermore, Zer reduced the caspase-1 activity without altering cytosolic NLRP3 content in challenged M2 BMDMs. We also observed that Zer significantly enhanced M2-associated marker's expression, e.g., Arg-1, Ym-1, and Fizz-1, and augmented Nrf-2 and other antioxidant proteins, including HMOX1 and srxn1expression following Pam3CSK4 + sUA treatment. We draw the conclusion that Zer is a potentially effective anti-inflammatory treatment for gout arthritis linked to hyperuricemia.

Assessing medication adherence and their associated factors amongst type-2 diabetes mellitus patients of Jazan Province, Saudi Arabia: A single-center, cross-sectional study.

Background: The prevalence of type 2 diabetes mellitus (T2DM) globally is reaching epidemic proportions. By 2035, it is projected to increase to 417 million, which is of significant concern as T2DM represents the most oversized budget item in many healthcare systems, primarily due to the high rates of morbidity and mortality associated with the disease. The worldwide cost burden of T2DM has been inexorably growing. A key contributor to the remarkably high morbidity and mortality rates is poor glycemic control potentially associated with medication non-adherence. Aim: The present research's main objective included assessing medication adherence among patients with T2DM in a single center in Jazan Province. Methods: Three hundred nine patients with T2DM participated in a cross-sectional survey over three months (September to November 2022). The study participants comprised 50.8 % (females) and 49.2 % (males), with a mean age of 44.12 years (SD ± 12.70). A 31-item self-report questionnaire was used for data collection. Results: Sixty-six percent of the sample were found to be adherent to their T2DM therapy. A positive association was noticed between the GMAS score and the participant's age (r = 0.24; p < 0.01). The participants' medication adherence was significantly associated with having age above 50 years (χ2 = 13.62; p = 0.001), residing in urban localities (χ2 = 21.37; p < 0.001), being married (χ2 = 12.80; p = 0.002), having glycated hemoglobin level more than 8 % (χ2 = 6.99; p = 0.03) and taking between one to three medications per day (χ2 = 17.63; p < 0.001). Conclusion: The majority of T2DM patients in the present study were found adherent to their anti-diabetic medications, particularly older patients. Future studies should focus on exploring the reasons for the reported high adherence among older patients and non-adherence among younger patients, as this could facilitate the development of a strategy to enhance adherence.

Thymoquinone Ameliorates Carfilzomib-Induced Renal Impairment by Modulating Oxidative Stress Markers, Inflammatory/Apoptotic Mediators, and Augmenting Nrf2 in Rats.

Chemotherapy-induced kidney damage is an emerging problem that restricts cancer treatment effectiveness. The proteasome inhibitor carfilzomib (CFZ) is primarily used to treat multiple myeloma and has been associated with severe renal injury in humans. CFZ-induced nephrotoxicity remains an unmet medical need, and there is an urgent need to find and develop a nephroprotective and antioxidant therapy for this condition. Thymoquinone (TQ) is a bioactive compound that has been isolated from Nigella sativa seeds. It has a wide range of pharmacological properties. Therefore, this experimental design aimed to study the effectiveness of TQ against CFZ-induced renal toxicity in rats. The first group of rats was a normal control (CNT); the second group received CFZ (4 mg/kg b.w.); the third and fourth groups received TQ (10 and 20 mg/kg b.w.) 2 h before receiving CFZ; the fifth group received only TQ (20 mg/kg b.w.). This experiment was conducted for 16 days, and at the end of the experiment, blood samples and kidney tissue were collected for biochemical assays. The results indicated that administration of CFZ significantly enhanced serum marker levels such as BUN, creatinine, and uric acid in the CFZ group. Similarly, it was also noticed that CFZ administration induced oxidative stress by reducing antioxidants (GSH) and antioxidant enzymes (CAT and SOD) and increasing lipid peroxidation. CFZ treatment also enhanced the expression of IL-1ß, IL-6, and TNF-α production. Moreover, CFZ increased caspase-3 concentrations and reduced Nrf2 expression in the CFZ-administered group. However, treatment with 10 and 20 mg/kg TQ significantly decreased serum markers and increased antioxidant enzymes. TQ treatment considerably reduced IL-1ß, IL-6, TNF-α, and caspase-3 concentrations. Overall, this biochemical estimation was also supported by histopathological outcomes. This study revealed that TQ administration significantly mitigated the negative effects of CFZ treatment on Nrf2 expression. Thus, it indicates that TQ may have utility as a potential drug to prevent CFZ-induced nephrotoxicity in the future.

Healthcare professionals' awareness, attitudes and practices towards pharmacovigilance and spontaneous adverse drug reaction reporting in Jazan Province, Saudi Arabia: A survey study.

Background: Globally, adverse drug reactions (ADRs) are the foremost cause of morbidity as well as mortality. This necessitates a system of surveillance that can effectively and efficiently monitor the effect of drugs on the general population. The role of pharmacovigilance (PV) is paramount in ensuring drug safety through spontaneous ADR reporting. Methods: Data collection in the current research was carried out by an anonymous, online 36-item self-report questionnaire amongst a sample of 351 working healthcare professionals (HCPs) across different regions of Jazan Province, Kingdom of Saudi Arabia (KSA). The current sample comprised 54.4% males and 45.6% females, having an age range of 26-57 years, and was conducted between August 21 and October 21, 2022. Participants were recruited using the convenience snowball sampling technique. Results: The participants' awareness of PV as well as spontaneous ADR reporting, had a significant association with having <40 years of age (χ2 = 27.40; p < 0.001), being pharmacists (χ2 = 212.20; p < 0.001), with more than five years of experience (χ2 = 40.80; p < 0.001), having Masters (or) Doctorate/Fellowship (χ2 = 171.94; p < 0.001), and having their practice located in an urban area (χ2 = 50.30; p < 0.001). It was also observed that most participants with excellent awareness of PV and spontaneous ADR reporting also demonstrated excellent attitudes (χ2 = 147.70; p < 0.001). Similarly, it was also seen that almost all (97%) of the study sample with excellent attitudes towards PV and spontaneous ADR reporting also demonstrated excellent practices (χ2 = 250.73; p < 0.001). Conclusion: Our results demonstrate a need for designing and conducting educational programs, providing training and conducting workshops for all the HCPs to improve their awareness towards PV and spontaneous ADR reporting while also highlighting the need and importance of having positive attitudes towards spontaneous ADR reporting. Cooperation between different HCPs should be encouraged to improve their practices towards spontaneous ADR reporting.

Self-reported and the actual involvement of community pharmacy professionals in the management of acute childhood diarrhea in Jazan Province, Saudi Arabia: Simulated patient visits and survey study.

Background: Acute childhood diarrhea is one of the most common causes of dehydration, and if severe, can potentially lead to death as well. The present study was aimed at evaluating the knowledge and attitudes of community pharmacy professionals towards the management of acute childhood diarrhea and comparing them with their actual practices in Jazan Province, Kingdom of Saudi Arabia (K.S.A). Methods: Simulated patient visits and a cross-sectional survey making use of a 27-item self-report questionnaire were conducted amongst a sample of 303 community pharmacy professionals (51.2 % male and 48.8 % female) with an age range of 25-56 years, between August 1 and December 1, 2021, in Jazan Province, Saudi Arabia. Convenience sampling technique was used for the recruitment of the participants. Results: Significant positive correlations were seen between knowledge score (self-report survey) and practice score (simulated patient visit) regarding patients' history taking (r = 0.65; p < 0.01), drug recommendations (r = 0.71; p < 0.01) and providing information regarding food and fluid intake (r = 0.44; p < 0.01). The alpha coefficients for all the items of the survey instrument were noted to be greater than (or) equal to the 0.70 threshold for almost all sections, hence indicating good reliability and internal consistency of the developed scale. Conclusion: In the present study, even though we observed improved participants' performance during the self report survey, their performance level greatly dropped in actual practice. This warrants for a need for educational programs to improve their actual dispensing practices. The present study has also shown simulated patient visits to be a reliable, simple and a robust method of assessing the actual dispensing practices of community pharmacy professionals.

Knowledge and Attitude of First-Aid Treatments for Snakebites, and the Perception of Snakes among the Students of Health Sciences at Jazan University, Saudi Arabia.

First aid is the most basic and life-saving service provided before emergency care is received. This study aimed to assess students' knowledge and attitudes about performing first aid for snakebite emergencies and their perception of snakes. A cross-sectional study was conducted between January and March 2019 among upper-level students (3rd year and above) of health-related courses at Jazan University, Saudi Arabia. Three hundred and nine students from four programs responded to the self-administered questionnaire. The collected data were analyzed using SPSS 23.0. The highest percentage of the study sample comprised pharmacy students (44%), followed by nursing (25.2%), medical (16.8%), and emergency medicine students (13.9%). Overall, the emergency medicine students exhibited greater knowledge of snakebite first aid. However, over three-fourths of the students were unaware of dry bites. Around two-thirds were sure that they should not massage the bite site, while nearly one-fourth were not sure about the use of a tourniquet. The fifth- and sixth-year students had extremely diverse perspectives on snakes. The majority of the participants (92.8%) did not feel good about snakes. However, most of the students (95.2%) wanted to learn about snakebite first aid and overcome their fear of snakes. Overall, the students had a positive attitude towards first aid but lacked knowledge of snakebite emergencies. Public health awareness is required to dispel first-aid myths about snakebites and misconceptions regarding snakes.
