Background Pharmacological therapies are key component of effective smoking-cessation management; however, the extent to which community pharmacists are prepared to deliver these interventions remains unclear. Objective This study explored the knowledge, attitudes, and practical engagement of community pharmacists toward pharmacological interventions of smoking cessation, and to examine the influence of demographic factors on these outcomes. Methods A cross-sectional survey was conducted between January and August 2024 among licensed community pharmacists in Saudi Arabia. A structured questionnaire, distributed contained four sections: demographics, knowledge, attitudes, and practices. Results A total of 213 pharmacists participated (92% male, 80.8% non-Saudi), mostly aged 25–34 years and holding a bachelor’s degree (94.8%). Mean scores indicated moderate levels of knowledge (6.31 ± 2.7/10), attitude (13.07 ± 6.5/25), and practice (6.85 ± 2.1/12) toward smoking cessation. Although nearly one-third of pharmacists (30.5%) consistently referred patients to Ministry of Health cessation programs, routine assessment of smoking status was less common, with only 17.8% regularly asking patients whether they smoked. Reliability was good-to-excellent (α = 0.800–0.951). Knowledge correlated positively with practice ( r  = 0.203, p  = 0.003) but negatively with attitude ( r = − 0.244, p  < 0.001). Higher knowledge was associated with younger age ( p  = 0.035). Practice scores were higher among pharmacists from the Northern ( p  = 0.001) and Eastern regions ( p  = 0.006), and among those with prior smoking-cessation training ( p  = 0.012). Conclusion Community pharmacists in Saudi Arabia demonstrated moderate levels of knowledge, attitudes, and practices related to pharmacological smoking-cessation interventions. Knowledge was positively associated with practice but negatively with attitudes. Practice levels varied significantly by region and were higher among pharmacists who had received prior training, highlighting the importance of targeted professional development and better integration of smoking cessation services into community pharmacy practice.

Alcohol use disorder (AUD) represents a significant global health burden, characterized by high relapse rates and limited treatment options. Valproic acid, primarily used as an anticonvulsant and mood stabilizer, has been suggested as a potential therapeutic agent for AUD, particularly in patients with coexisting psychiatric conditions. This study systematically analyses clinical trials from ClinicalTrials.gov to evaluate the efficacy of valproic acid in treating AUD. A systematic search of ClinicalTrials.gov was conducted to identify clinical trials involving valproic acid in the management of substance use disorder (SUD). A total of 3,822 studies related to SUD were initially identified. Screening for anticonvulsant use narrowed this to 96 trials, and four completed studies specifically involving valproic acid and AUD were included in the final analysis. Key outcomes related to relapse rates, substance use reduction, mood stabilization, and withdrawal symptoms were examined. The included studies focused on various conditions, including alcohol dependence, bipolar disorder with substance abuse, traumatic brain injury with alcohol use, and medication-overuse headache. Valproic acid demonstrated potential benefits in reducing alcohol consumption, stabilizing mood, and managing withdrawal symptoms in specific subpopulations. However, relapse rates remained high in some trials, indicating limited long-term efficacy. Secondary outcomes showed improvements in psychiatric symptoms, though adverse effects such as sedation and gastrointestinal disturbances were noted. Valproic acid shows potential as a therapeutic option for managing AUD, particularly in individuals with coexisting psychiatric conditions or complex clinical profiles. While the drug showed some efficacy in reducing substance use and stabilizing mood, the overall impact on long-term abstinence remains uncertain. Further research is needed to better define the role of valproic acid in AUD treatment and to identify patient populations that may benefit most from its use.

Many people still struggle with quitting smoking despite available treatment options, making it one of the most significant public health challenges that our society faces. The use of electronic cigarettes (E-cigarettes) has become increasingly popular among people who are seeking to quit smoking. The objective of this review paper is to present a comprehensive analysis of the mechanisms, several types, and impact of E-cigarettes, along with supporting evidence indicating their efficacy in aiding smokers to quit tobacco usage. Additionally, the review discusses recent developments in the treatment of smoking cessation, which include conventional smoking cessation methods. Also, the review discusses the challenges, potential risks, ethical considerations, and controversies surrounding the use of E-cigarettes. The present review presents a comprehensive examination of the existing methods and approaches employed in smoking cessation, including the emerging utilization of E-cigarettes as an effective option in smoking cessation. It explores their efficacy as a valuable instrument in promoting smoking cessation.

Research on the use of biodegradable polymers for drug delivery has been ongoing since they were first used as bioresorbable surgical devices in the 1980s. For tissue engineering and drug delivery, biodegradable polymer poly-lactic-co-glycolic acid (PLGA) has shown enormous promise among all biomaterials. PLGA are a family of FDA-approved biodegradable polymers that are physically strong and highly biocompatible and have been extensively studied as delivery vehicles of drugs, proteins, and macromolecules such as DNA and RNA. PLGA has a wide range of erosion times and mechanical properties that can be modified. Many innovative platforms have been widely studied and created for the development of methods for the controlled delivery of PLGA. In this paper, the various manufacturing processes and characteristics that impact their breakdown and drug release are explored in depth. Besides different PLGA-based nanoparticles, preclinical and clinical applications for different diseases and the PLGA platform types and their scale-up issues will be discussed.

Background and Objectives: Numerous studies have indicated that antibiotics may adversely affect testicular and sperm function. As an alternative to penicillin, vancomycin is a glycopeptide antibiotic developed to treat resistant strains of Staphylococcus aureus. A few studies have suggested that vancomycin could cause testicular toxicity and apoptosis. Vancomycin, however, has not been investigated in terms of its mechanism of causing testicular toxicity. Materials and Methods: An experiment was conducted to investigate the effects of resveratrol (20 mg/kg, oral gavage) against vancomycin (200 mg/kg, i.p.) on the testicular function of Wistar rats for one week (7 days). There were three subgroups of animals. First, saline (i.p.) was administered to the control group. Then, in the second group, vancomycin was administered. Finally, vancomycin and resveratrol were administered in combination in the third group. Results: After seven days of vancomycin treatment, testosterone levels, sperm counts, and sperm motility were significantly reduced, but resveratrol attenuated the effects of vancomycin and restored the testosterone levels, sperm counts, and sperm motility to normal. In the presence of resveratrol, the vancomycin effects were attenuated, and the luteinizing hormone and follicular hormone levels were normalized after seven days of treatment with vancomycin. Histologically, vancomycin administration for seven days caused damage to testicular tissues and reduced the thickness of the basal lamina. However, the resveratrol administration with vancomycin prevented vancomycin’s toxic effects on testicular tissue. Conclusion: Resveratrol showed potential protective effects against vancomycin-induced testicular toxicity in Wistar rats.

Objective. This study provides a comprehensive analysis of the characteristics of clinical trials related to alcohol dependence that are registered on ClinicalTrials.gov. Methods. All ClinicalTrials.gov trials registered up to 1 January 2023 were examined, focusing on trials that involved alcohol dependence. All 1295 trials were summarized by presenting their characteristics and results and reviewed most intervention drugs used in the treatment of alcohol dependence. Results. The study analysis identified a total of 1295 clinical trials registered on ClinicalTrials.gov that were focused on alcohol dependence. Of these, 766 trials had been completed, representing 59.15% of the total, while 230 trials were currently recruiting participants, accounting for 17.76% of the total. None of the trials had yet been approved for marketing. The majority of the studies included in this analysis were interventional studies (1145 trials, or 88.41%), which accounted for most of the patients enrolled in the trials. In contrast, observational studies represented only a small portion of the trials (150 studies, or 11.58%) and involved a smaller number of patients. In terms of geographic distribution, the majority of registered studies were located in North America (876 studies, or 67.64%), while only a small number of studies were registered in South America (7 studies, or 0.54%). Conclusions. The purpose of this review is to provide a basis for the treatment of alcohol dependence and prevention of its onset through an overview of clinical trials registered at ClinicalTrials.gov. It also offers essential information for future research to guide future studies.

Cannabinoids have gained increasing attention for their therapeutic potential in treating several neurological conditions, including neurodegenerative diseases, chronic pain, and epilepsy. This review aims to assess the current clinical trials investigating cannabinoids, primarily Tetrahydrocannabinol and Cannabidiol, for neurological disorders. This review will aim to highlight the efficacy, safety, and outcome measures used in these trials. Clinical trials were identified using ClinicalTrials.gov, focusing on studies that examined the effects of cannabinoids in treating neurological conditions. All trials that fulfilled the following criteria were included: Phase 1-4, focused on cannabinoids as primary intervention, and measured relevant outcomes such as pain relief, cognitive function, or spasticity reduction. Data on conditions, interventions, primary and secondary outcomes, and trial phases were extracted and analysed. A total of 47 clinical trials were identified, including different neurological conditions. The most frequently studied conditions were Multiple Sclerosis, Fibromyalgia, and Parkinson's Disease. Most trials were in Phase 2, with the primary outcome measures focused on pain management, spasticity, and cognitive function. Secondary outcomes included safety and tolerability measures. The review highlights the broad therapeutic potential of cannabinoids in neurology, with promising results in symptom management for conditions like Multiple Sclerosis and Fibromyalgia. However, the lack of standardized study protocols, dosing, and outcome measures presents challenges for broader clinical implementation. clinicatrials.gov.

Factor XIII (FXIII) is a transglutaminase enzyme that catalyses the formation of ε-(γ-glutamyl)lysyl isopeptide bonds into protein substrates. The plasma form, FXIIIA2B2, has an established function in haemostasis, with fibrin being its principal substrate. A deficiency in FXIII manifests as a severe bleeding diathesis emphasising its crucial role in this pathway. The FXIII-A gene (F13A1) is expressed in cells of bone marrow and mesenchymal lineage. The cellular form, a homodimer of the A subunits denoted FXIII-A, was perceived to remain intracellular, due to the lack of a classical signal peptide for its release. It is now apparent that FXIII-A can be externalised from cells, by an as yet unknown mechanism. Thus, three pools of FXIII-A exist within the circulation: plasma where it circulates in complex with the inhibitory FXIII-B subunits, and the cellular form encased within platelets and monocytes/macrophages. The abundance of this transglutaminase in different forms and locations in the vasculature reflect the complex and crucial roles of this enzyme in physiological processes. Herein, we examine the significance of these pools of FXIII-A in different settings and the evidence to date to support their function in haemostasis and wound healing.

During the Hajj and Umrah seasons in Saudi Arabia, pilgrims tend to experience a higher frequency of various health conditions. Respiratory infections, gastrointestinal infections, and food poisoning are among the most prevalent ailments. To address these health concerns, community pharmacists (CPs) have developed standardized treatment protocols. Pharmacists' skills in medication dispensing, health consultations, and preventive care enhance pilgrims' well-being in challenging pilgrimage settings. The objective of this study was to investigate the knowledge and attitude of CPs towards health conditions related to Hajj and Umrah in the Western Region of Saudi Arabia where the Hajj and Umrah are taking place. Between March and April 2023, an online cross-sectional study using Google form was carried out among CPs who work in the western region of Saudi Arabia. The study made use of a self-administered questionnaire consisting of four sections that aimed to obtain information about the CPs' knowledge and attitudes towards health conditions related to Hajj and Umrah. Data analysis was conducted using the Statistical Package for the Social Sciences version 26 (SPSS). A total of 496 CPs completed and returned the questionnaire, by giving a response rate of 99.2% (n = 500). Among them, 55.1% were aware of the necessary vaccines for Hajj and Umrah. Approximately 46.6% of CPs provided health-related advice to pilgrims. The most common health conditions experienced by pilgrims were diarrhea (59.5%), followed by flu and cough (58%), gastrointestinal diseases (39.4%), food poisoning (33.6%), viral fever, and heat stroke (24.4%). Regarding attitudes towards vaccination, 55.3% of CPs agreed that vaccination is safe for pilgrims aged 65 years and above, and 65.7% agreed that vaccination can help reduce medical costs during Hajj and Umrah seasons. Additionally, 61.1% of CPs recommended updating immunization against vaccine-preventable diseases for all travelers to ensure a safe Hajj and Umrah. The overall mean knowledge of CPs regarding vaccination during Hajj and Umrah was 4.739(2.49) (median = 5; Range = 0-9). However, 56.7% of CPs demonstrated good knowledge, while 43.3% reported poor knowledge regarding vaccination during Hajj and Umrah. The community pharmacists (CPs) in the Mecca region were found to have good knowledge, with more than half of them having positive attitudes about vaccination for Hajj and Umrah-related health conditions. It is crucial to enhance the knowledge and attitudes of CPs to provide better care and participate in reliable and supportive healthcare and counseling sessions for managing various health infections.

Background: Vancomycin is a glycopeptide antibiotic with a high risk of acute liver injury. Resveratrol is believed to protect the liver against toxicity. Aim: To investigate the ability of resveratrol to attenuate vancomycin-induced liver toxicity in rats injected with vancomycin. Method: Twenty-four adult male Wistar rats were distributed into three groups. The control group received only a vehicle, while the treated group received either vancomycin 200 (mg/kg, i. p.) only or vancomycin (200 mg/kg, i. p.) with resveratrol (20 mg/kg, oral gavage). All groups received their dose once daily for 7 days. Hepatic damage was assessed by measuring biochemical parameter levels in serum, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH). Also, antioxidants and inflammation biomarkers such as Interleukin-6 (IL-6), malondialdehyde (MDA), nitric oxide (NO), and glutathione (GSH) were measured. Furthermore, the vancomycin-induced pathological changes in the liver were evaluated by histopathological studies. Results: In the vancomycin-treated group, hepatic serum biomarkers such as AST, ALT, ALP, IL-6, and MDA were elevated, while NO and GSH were depleted. However, resveratrol co-treatment with vancomycin prevented the elevation of AST, ALT, ALP, IL-6, and MDA and it protected the liver from NO and GSH depletion. Also, regarding vancomycin-induced degeneration of hepatocytes, resveratrol co-treatment with vancomycin prevented such degeneration and improved mononuclear cells in the liver. Conclusion: The results showed that oral administration of resveratrol has a significant hepatoprotective effect against vancomycin-induced hepatotoxicity.
