Examining factors influencing public knowledge and practice of proper face mask usage during the COVID-19 pandemic: a cross-sectional study.

Background: The COVID-19 pandemic had an enormous impact on people's quality of life worldwide. Appropriate use of facemasks is an important checkpoint in containing the spread of infection, which was believed to provide the desired level of protection and preserve the community. Given the relative novelty of facemask use in the general population, it is imperative to prioritize the promotion of appropriate facemask utilization and identify factors that may contribute to poor adherence. Aim: This study assessed the factors that determined facemask use among the public. Methods: A cross-sectional questionnaire-based study was conducted among the residents of the Kingdom of Saudi Arabia between November 2020 and January 2021. The current study explored the factors such as demographic characteristics influencing the knowledge and practice of proper use of facemasks. The study included a total of 198 participants. The results were derived through binomial logistic regression analysis to determine the relationship between the demographic characteristics and responses. Results: The key findings of the study which are crucial in developing targeted intervention strategies to enhance the responsible use and disposal of facemasks are gender, income and employment. A significant difference was found between male and female participants regarding a positive approach to using facemasks, such as washing their hands (P = 0.042). In addition, homemakers differed significantly from students, regarding the correct usage of facemasks (P = 0.026). The study participants were aware that hand hygiene is essential when putting on and removing facemasks. Despite wearing facemasks properly, adult participants possessed less knowledge about the hazards of reusing facemasks and appropriate disposal (OR = 0.202, 95% CI [0.032-1.298]). Conclusion: The present research identified gender, income, and employment as the primary attributes that play a pivotal role in the formulation of focused intervention tactics aimed at improving the cautious use and appropriate disposal of facemasks. It is essential to implement nationwide awareness activities, such as information campaigns, to enhance knowledge. Health authorities should establish a functional infrastructure for the collection and disposal of used facemasks by the general public, starting with the dissemination of knowledge. Moreover, the results of the present study have significant implications for health preventive programs aimed at preparing for future pandemics, since they highlight the specific demographic groups that should be prioritized in the development of such policies. Furthermore, it is advisable to integrate these interventional initiatives with national health polices to promote preparedness for handling future pandemics.

Comparing knowledge, attitudes, and practices in cardiovascular disease prevention and health promotion between community and hospital pharmacists in Saudi Arabia: A cross-sectional study.

Purpose: Saudi Arabia is one of the leading nations in the world in terms of the high frequency of chronic diseases and their associated risk factors. Knowledge and awareness are crucial for pharmacists to play an active role in the prevention of cardiovascular diseases (CVD). The current study assessed the pharmacists' knowledge, attitude, and practice to determine the potential differences with respect to their respective practice settings toward CVD prevention and related health promotions. Methods: It is a cross-sectional study targeted the registered pharmacists in the Kingdom of Saudi Arabia. An online questionnaire was prepared, and the link was circulated through various social media platforms. Descriptive statistics, multivariate linear regression analysis and chi square test were used to analyze the data accordingly. Results: A total of 324 pharmacists were included in the study. Among these, 157 (48.4 %) were community pharmacists, and the remaining were hospital pharmacists (51.6 %). No significant differences in knowledge scores were observed between community and hospital pharmacists. The mean attitude score among community and hospital pharmacists was found to be 26.40 ± 5.125 and 25.09 ± 5.393 respectively, which was statistically significant (p = 0.026). Similarly, the total practice scores across the settings were statistically significant (p = 0.02). Gender plays a significant role in terms of knowledge scores among both community and hospital pharmacists (p = 0.016 & 0.029). Gender, professional practice experience, and number of prescriptions handled and prescriptions with CVD medications showed significant differences in the distribution of positive attitudes and good practice frequency between community and hospital pharmacists. Conclusion: It is evident that there is a deficiency in knowledge among hospital pharmacists compared to community pharmacists. Which indicates that there is a need for a rigorous continuous pharmacy education covering the fundamental aspects of CVD primary prevention and health promotion among pharmacists, given more focus on hospital pharmacists.

Knowledge, Attitudes, and Practices Related to Cervical Cancer Prevention and Screening among Female Pharmacy Students at a Public University in a Southern Region of Saudi Arabia.

Despite the availability of human papillomavirus (HPV) vaccines and screening facilities at various health centers in Saudi Arabia, the annual death rate due to cervical cancer is high. Therefore, knowledge and awareness are essential for self-care and educating others, particularly among healthcare students. The present descriptive, cross-sectional study explored female pharmacy students' knowledge, attitudes, and practices related to cervical cancer. A total of 140 students participated in the survey. The survey was conducted for the period between April 2022 to September 2023. We observed a good knowledge score and positive attitudes among 8.5% and 93.5% of participants, respectively. A total of 10% of the study participants reported good practice scores. Most participants had never been screened for cervical cancer (94.3%). Among the non-screened subjects, feeling healthy and lacking information were the participants' significant reasons for not screening for cervical cancer. A positive history of cancer related to smoking significantly impacted the knowledge score (p = 0.050). The current study reveals that healthcare awareness programs for cervical cancer and HPV vaccination are necessary at the level of educational institutions to improve public health.

Cardiovascular Disease-Related Health Promotion and Prevention Services by Pharmacists in Saudi Arabia: How Well Are They Prepared?

BACKGROUND: Cardiovascular diseases (CVDs) have been identified as the leading reason for morbidity and mortality in Saudi Arabia. Pharmacists play a major role in CVD prevention and health promotion. We aimed to assess the knowledge, attitudes, and involvement of pharmacists in CVD prevention and evaluate the influence of continuing medical education in CVD-prevention services in Saudi Arabia. METHOD: A cross-sectional study was conducted to evaluate the involvement of pharmacists in CVD-related prevention services along with their knowledge and attitudes. A 34-item questionnaire was developed and distributed among the participants. RESULTS: A total of 324 responses were included in the study. More than 60% of pharmacists had provided counseling regarding the importance of healthy lifestyles and self-monitoring CVD risk factors. About half of the participants (49.1%) had never received any CVD-related continuing medical education. Overall, more than 60% of the participants reported positively towards their role in CVD prevention. Lack of time (66%) and lack of educational materials and tools (41%) were the top perceived barriers for providing CVD-prevention and health-promotion activities, followed by lack of skills in using tools (36%) and lack of privacy/space (33%). CONCLUSIONS: The involvement of pharmacists in the prevention of CVD is limited in this study. Further education and capacity building are required to strengthen pharmacists' involvement in CVD-prevention and health-promotion activities.

Patient Safety Culture in the Southern Region of Saudi Arabia: A Survey among Community Pharmacies.

Measuring patient safety culture in the community pharmacy can help with identifying areas for development. The current study is a descriptive, cross-sectional, electronic survey conducted among pharmacists working in community pharmacies located in the southern region of Saudi Arabia. The community pharmacy version of the "Pharmacy Survey on Patient Safety Culture" (PSOPSC) was used to collect data. The positive response rate (PRR) was calculated as per the guidance provided by the Agency for Healthcare Research and Quality (AHRQ). Based on the PRR, two least-achieved items (<25%) were taken for further analysis to identify the possible predictors. A sum of 195 pharmacists were included in this study and most of them were working in chain pharmacies. The highest PRRs were observed with teamwork (94.99), and patient counseling (94.13), followed by physical space and environment (93.07). The lowest PRRs were observed with staffing, work pressure, and pace (47.70), followed by communication openness (72.60). Specific characteristics, such as experience and the number of working hours, are significantly related to a poor PRR. The current study results indicate that the scope for improving patient safety exists in various areas of community pharmacies. However, it is necessary to prioritize the need based on a positive response rate.

Unraveling the Differentially Articulated Axes of the Century-Old Renin-Angiotensin-Aldosterone System: Potential Therapeutic Implications.

Among numerous choices in cardiovascular therapies used for the management of hypertension and heart failure, drugs affecting the renin-angiotensin-aldosterone system (RAAS) hold substantial therapeutic roles. Therapies aimed at modifying the RAAS and its overactivation are employed for the management of various insidious disorders. In the pharmacologic perspective, RAAS is one of the frequently manipulated systems for the management of hypertension, heart failure, myocardial infarction, and renal disease. The RAAS pharmacologic interventions principally include the ACE inhibitors, the angiotensin II-AT1 receptor blockers, the mineralocorticoid receptor antagonists, and the direct renin inhibitors. In addition, therapeutic implication of ACE2/angiotensin (1-7)/Mas receptor activation using various ligands is being explored owing to their anti-inflammatory, anti-fibrotic, vasodilatory, and cardiovascular defensive roles. Moreover, being considered as the counter-regulatory arm of AT1 receptor, the potential role of AT2 receptor activation using selective AT2 receptor agonist is currently investigated for its efficacy in pulmonary complications. As an important regulator of fluid volume, blood pressure, and cardiovascular-renal function, the RAAS has been documented as a diversified intricate system with several therapeutic possibilities coupled with their fundamental structural and functional modulatory roles in cardiovascular, renal, and other systems. The RAAS possesses a number of regulatory, deregulatory, and counter-regulatory axes of physiopathologic importance in health and disease. The counter-regulatory arms of the RAAS might play an essential role in mitigating cardiovascular, renal, and pulmonary pathologies. In light of this background, we sought to explore the classical and counter-regulatory axes/arms of the RAAS and their imperative roles in physiologic functions and disease pathogenesis.

The physiologic and physiopathologic roles of perivascular adipose tissue and its interactions with blood vessels and the renin-angiotensin system.

The perivascular adipose tissue (PVAT) refers to an ectopic local deposit of connective tissue that anatomically surrounds most of the blood vessels. While it was initially known only as a structural support for vasculature, the landmark findings of Soltis and Cassis (1991), first demonstrating that PVAT reduces the contractions of norepinephrine in the isolated rat aorta, brought the potential vascular role of PVAT into the limelight. This seminal work implied the potential ability of PVAT to influence vascular responsiveness. Several vasoactive/vasocrine substances influencing vascular homeostasis were successively shown to be released from PVAT that include both adipocyte-derived relaxing and contracting factors. The PVAT is currently recognized as a metabolically active endocrine organ and is eventually considered as the 'protagonist' in vascular homeostasis. It plays prominent defending and opposing roles in vascular function, while the actual vascular influences of PVAT vary with an increase in adiposity. Recent studies have presented compelling evidence implicating the pivotal role of PVAT in the local activation of the renin-angiotensin system (RAS), which substantially impacts vascular physiology and physiopathology. Current findings have advanced our understanding of the role of PVAT in favorably or adversely modulating the vascular function through differential RAS activation. Given that adipocytes also produce major RAS components locally to influence vascular function, this review provides a scientific basis to distinctly understand the key role of PVAT in regulating the autocrine and paracrine functions of vascular RAS components and its potential as an emerging therapeutic target for mitigating cardiovascular complications.

Evaluation of Antibiotic Prescribing Practices and Antimicrobial Sensitivity Patterns in Urinary Tract Related Infectious Diseases in Pediatric Patients.

Complications of urinary tract infections (UTIs) like kidney failure and septicaemia develop once infections spread from the upper urinary tract to other parts of the body by haematogenous dissemination and they pose great health and economic burden to the countries. This retrospective study was conducted among 132 patients with bacterial UTIs in the inpatient department of tertiary care hospital in Abha, Saudi Arabia. During the study period, Escherichia coli (E. coli) and Klebsiella pneumonia (K. pneumonia) along with other 15 different bacteria were isolated. A significant difference (P < 0.05) was observed between the male and female children population in different age groups. We observed fever (84.09%) as a major symptom (P < 0.05), and seizure (9%) was reported as a major concomitant condition among UTI cases. Around 31.82% of E. coli was found to be the most common uropathogens in pediatric cases followed by 25% in K. pneumoniae. E. coli was observed to be more susceptible (92.86%) to amikacin, ceftriaxone, levofloxacin, ertapenem, gentamycin, meropenem, piperacillin-tazobactam, tigecycline, and ceftazidime. However, meropenem, tigecycline, and amikacin were observed to be effective in 100% of cases of K. pneumoniae. Meanwhile, cephalosporins were the most commonly prescribed drug category among different classes of drugs. Almost 99% of pediatric cases, based on their age, were admitted to the ward, and drugs were administered intravenously. We concluded that microbiology laboratory evidence on the causative organisms and choice of treatment together allows tailoring appropriate treatment regimens in conjunction with clinical experiences.

Mechanistic insights into hyperuricemia-associated renal abnormalities with special emphasis on epithelial-to-mesenchymal transition: Pathologic implications and putative pharmacologic targets.

Though the pathogenesis of hyperuricemia-induced renal complications is not precisely known, hyperuricemia has been recognized as an independent risk factor for renal disease. While the clinical implication of hyperuricemia in renal disease has been a contemporary topic of debate, growing body of bench and clinical evidences certainly suggest a causative role of high uric acid in renal abnormalities by implicating diverse pathologic and molecular mechanisms. Urate crystals after having deposited in the kidney could cause hyperuricemia nephropathy leading to glomerular hypertrophy and tubulointerstitial fibrosis, while high serum uric acid might predict progressive renal damage and dysfunction. Hyperuricemia could be associated with manifestation of tubular injury and macrophage infiltration as well as an increased expression of inflammatory mediators. This review sheds light on the mechanistic aspects pertaining to hyperuricemia-associated renal abnormalities. Besides, the renal detrimental actions of high uric acid possibly mediated through its potential role on oxidative stress, renal inflammation, endothelial dysfunction, glycocalyx shedding, endothelial-to-mesenchymal transition and more specifically on the renal epithelial-to-mesenchymal transition have been addressed. Moreover, this review discusses a number of potential targets such as endothelin-1, TLR4/NF-kB, PI3K/p-Akt, Wnt5a/Ror2, NLRP3 inflammasome, NADPH oxidase, ERK1/2, enhancer of zeste homolog 2, serum response factor and Smad3/TGF-ß signalling pathways, among others, implicated in hyperuricemia-associated renal abnormalities. This review finally apprises a number of bench and clinical studies which supporting a notion that the pharmacologic reduction of high uric acid might have a therapeutic value in the management of renal abnormalities, with an emphasis on febuxostat and its renal pleiotropic actions.

Prevalence and control of cardiovascular risk factors among type 2 diabetes mellitus patients in southern region of Saudi Arabia.

BACKGROUND/AIM: Dyslipidemia is a significant predictor of cardiovascular events and mortality in diabetes patients. The aim of this study is to estimate the prevalence rates, characteristics of dyslipidemia and their control in outpatient population in a Diabetic Centre. METHODS: A cross sectional prospective study design was used to collect data from 255 patients which included patient characteristics, past medical history of CVD, medications and parameters related to DM and cardiovascular risk factor control. Blood pressure and laboratory measurements for glycosylated hemoglobin and lipoprotein panel were recorded. RESULTS: Body mass index (BMI) of the dyslipidemic diabetic patients was significantly higher for females. In terms of age, duration of diabetes, family history, diabetes treatment offered did not differed significantly among genders. Clinical characteristics of HDL values were significantly higher for female in comparison to men (P = 0.02) whereas glycosylated hemoglobin and blood pressure appeared not to differ significantly. Among the three factors studied BMI, duration of diabetes mellitus and drug therapy on lipoprotein levels of diabetes patients, except for the influence of drug therapy which influenced significantly the total cholesterol level (P = 0.02). Number of females with normolipid were more than males (P = 0.009) and number of males with abnormal cholesterol and triglyceride patients were significantly more than females (0.0002). CONCLUSION: Dyslipidemia among males were higher than females which could be a significant risk factor for causing low glycemic control culminating in cardiovascular events. Control of hyperglycaemia and other CVD risk factor appears to be suboptimal in Saudi Arabia. Addressing health system components such as providing medical staff training, incentive to health professionals and better patient education may improve quality of DM care.
