PREVALENCE AND CORRELATION OF CONTRACEPTIVE USE AMONG FEMALES IN JEDDAH, SAUDI ARABIA

Objective: The purpose of this study was to examine the prevalence of contraceptive use and the correlates of contraceptive use among females in Jeddah, Saudi Arabia. Moreover, it aimed to evaluate the knowledge about contraceptives and their use. Methods: The study was a community-based, cross-sectional descriptive survey conducted in Saudi Arabia from 28 September 2015 to 10 December 2015. Results: The current study showed that the most commonly used contraceptives were intrauterine devices (IUD’s) (29.1%), followed by male condoms (27.7%). Most of the participants, 47.6%, started using a contraceptive after giving birth to their first child. Nearby, 60% of participants used contraceptives without a prescription or medical advice. Only 13.7 % of participants sought the advice of a pharmacist about which contraceptive they should use, while 30.6% and 24.2% of participants choose their contraceptive based on general knowledge and relatives’ experiences, respectively. Around 80% of participants stated that they did not have any problem while buying contraceptives from pharmacies without a prescription. Conclusion: Pharmacists and medical health providers need to fill this gap to improve the use of contraceptives

Factors influencing future career interests of pharmacy interns in Saudi Arabia: a survey from 25 colleges of pharmacy

Abstract Background Hundreds of pharmacists graduate from pharmacy colleges in Saudi Arabia, and various factors influence their choice of career pathway. Very few single-institution studies assessed career choices of pharmacy students with or without evaluating the influencing factors. Therefore, this study aimed to evaluate career choices and the associating factors of pharmacy interns from multiple colleges in Saudi Arabia. Methods This was a cross-sectional study that surveyed pharmacy interns from 25 pharmacy colleges in Saudi Arabia using an online questionnaire. The survey was sent during the last rotation month in the internship year (May–June 2022). Results Of 454 participants, 411 (90.5%) were enrolled in Doctor of Pharmacy programs. While most participants were interested in becoming clinical pharmacists (n = 183; 40.3%), a considerable number were also interested in working in different sectors of pharmaceutical companies and industry (n = 127; 28%). Internship training significantly correlated with selecting clinical pharmacy specialist career (r = 0.19; P = 0.0001), whereas salary/financial incentives significantly influenced the choice of working as sales and marketing representatives and pharmacy product specialists in pharmaceutical companies (r = 0.29 and 0.24; P < 0.0001 for both). College courses correlated with choosing academia in pharmaceutical sciences (r = 0.20; P < 0.0001), whereas summer training correlated with the community pharmacy career (r = 0.11; P = 0.02). Conclusion Pharmacy colleges should utilize results from this study to enhance the exposure of pharmacy students during their academic years to different pharmacy career pathways by allowing the opportunity to shadow pharmacists from different sectors as part of college courses, inviting previous graduates, and activating the role of academic advisors in career orientation

Metabolic Profiling and Investigation of the Modulatory Effect of <i>Fagonia cretica</i> L. Aerial Parts on Hepatic CYP3A4 and UGT2B7 Enzymes in Streptozotocin—Induced Diabetic Model

Drug-metabolizing enzymes are either boosted or suppressed by diabetes mellitus. This research was designed to explore Fagonia cretica L. aerial parts’ impact on CYP3A4 and UGT2B7 activity and their mRNA expression in diabetic rats. Fagonia cretica (F. cretica) dried powder was sequentially extracted with n-hexane, chloroform, ethyl acetate, methanol, and water. The methanol extract and aqueous fraction presented the most significant potential to decrease the concentration of alpha-hydroxyl midazolam, with 176.0 ± 0.85 mg/Kg and 182.9 ± 0.99 mg/Kg, respectively, compared to the streptozotocin (STZ)-induced diabetic group, reflecting the inhibition in CYP3A4 activity. The fold change in mRNA expression of CYP3A4 was decreased significantly by the methanol extract, and the aqueous fraction of F. cretica estimated by 0.15 ± 0.002 and 0.16 ± 0.001, respectively, compared with the diabetic group. Morphine metabolism was significantly increased in rats treated with F. cretica methanol extract and its aqueous fraction, displaying 93.4 ± 0.96 mg/Kg and 96.4 ± 1.27 mg/Kg, respectively, compared with the metabolism of morphine in the diabetic group, which highlights the induction of UGT2B7 activity. The fold change in mRNA expression of UGT2B7 was significantly increased by the methanol extract and the aqueous fraction, estimated at 8.14 ± 0.26 and 7.17 ± 0.23 respectively, compared to the diabetic group. Phytochemical analysis was performed using high-performance liquid chromatography (HPLC), where the methanol extract showed more flavonoids and phenolic compounds compared to the aqueous fraction of F. cretica. The obtained results were further consolidated by molecular docking studies, where quercetin showed the best fitting within the active pocket of CYP3A4, followed by gallic acid, displaying free binding energies (∆G) of −30.83 and −23.12 kcal/mol, respectively. Thus, F. cretica could serve as a complementary medicine with standard anti-diabetic therapy that can modulate the activity of the drug-metabolizing enzymes

Curative effects of fucoidan on acetic acid induced ulcerative colitis in rats via modulating aryl hydrocarbon receptor and phosphodiesterase-4

Abstract Background Ulcerative colitis (UC) is an inflammatory bowel disease. Fucoidan, sulfated polysaccharide of brown seaweed, demonstrates various pharmacological actions as anti-inflammatory, anti-tumor and anti-bacterial effects. Therefore, we opt to investigate the potential curative effects of fucoidan in experimentally induced UC in rats through modulating aryl hydrocarbon receptor (AhR), phosphodiesterase-4 (PDE4), nuclear factor erythroid 2-related factor 2 (Nrf2) and Heme Oxygenase-1 (HO-1). Methods UC was induced in rats using intracolonic 2 ml of 4% acetic acid. Some rats were treated with 150 mg/kg fucoidan. Samples of colon were used to investigate gene and protein expression of AhR, PDE4, Nrf2, HO-1 and cyclic adenosine monophosphate (cAMP). Sections of colon were stained with hematoxylin/eosin, Alcian blue or immune-stained with anti-PDE4 antibodies. Results Investigation of hematoxylin/eosin stained micro-images of UC rats revealed damaged intestinal glands, severe hemorrhage and inflammatory cell infiltration, while sections stained with Alcian Blue revealed damaged and almost absent intestinal glands. UC results in elevated gene and protein expression of PDE4 associated with reduced gene and protein expression of AhR, IL-22, cAMP, Nrf2 and HO-1. Finally, UC increased the oxidative stress and reduced antioxidant activity in colon tissues. All morphological changes as well as gene and protein expressions were ameliorated by fucoidan. Conclusion Fucoidan could treat UC induced in rats. It restored the normal weight and length of colon associated with morphological improvement as found by examining sections stained with hematoxylin/eosin and Alcian Blue. The curative effects could be explained by enhancing antioxidant activity, reducing the expression of PDE4 and increasing the expression of AhR, IL-22 and cAMP

Valorization of Pimenta racemosa Essential Oils and Extracts: GC-MS and LC-MS Phytochemical Profiling and Evaluation of Helicobacter pylori Inhibitory Activity

Pimenta racemosa is a commonly known spice used in traditional medicine to treat several ailments. In this study, comprehensive phytochemical profiling of the essential oils and methanol extracts of P. racemosa leaves and stems was performed, alongside assessing their potential Helicobacter pylori inhibitory activity in vitro and in silico. The essential oils were chemically profiled via GC-MS. Moreover, the methanol extracts were profiled using HPLC-PDA-ESI-MS/MS. The antibacterial activity of the essential oils and methanol extracts against H. pylori was determined by adopting the micro-well dilution method. GC-MS analysis unveiled the presence of 21 constituents, where eugenol represented the major component (57.84%) and (59.76%) in both leaves and stems of essential oils, respectively. A total of 61 compounds were annotated in both leaves and stems of P. racemosa methanolic extracts displaying richness in phenolic compounds identified as (epi)catechin and (epi)gallocatechin monomers and proanthocyanidins, hydrolyzable tannin derivatives (gallotannins), flavonoids, and phenolic acids. The stem essential oil showed the most promising inhibitory effects on H. pylori, exhibiting an MIC value of 3.9 &micro;g/mL, comparable to clarithromycin with an MIC value of 1.95 &micro;g/mL. Additionally, in silico molecular modeling studies revealed that decanal, eugenol, terpineol, delta-cadinene, and amyl vinyl showed potential inhibitory activity on H. pylori urease as demonstrated by high-fitting scores indicating good binding to the active sites. These findings indicate that P. racemosa comprises valuable phytochemical constituents with promising therapeutic effects, particularly the stem, an economic agro-industrial waste

Genistein ameliorated experimentally induced gastric ulcer in rats via inhibiting gastric tissues fibrosis by modulating Wnt/β-catenin/TGF-β/PKB pathway

ABSTRACTObjectives Gastric ulcer (GU) is a prevalent chronic digestive disease affecting about 10% of the world's population leading to gastrointestinal perforation and bleeding. Genistein is a legume flavonoid with antioxidants, anti-inflammatory and antibacterial activities. Therefore, we aimed to investigate the ability of genistein to reduce experimentally induced GU in rats by affecting gastric tissue fibrosis Wnt/β-catenin/TGF-β/SMAD4 pathway.Methods Thirty rats were used. Ten rats served as control, and GU was induced in twenty rats using a single dose of indomethacin (80 mg/kg) orally. Following induction of GU, ten were treated with genistein 25 mg/kg orally. The gastric tissues were isolated to investigate markers of gastric fibrosis, Wnt, β-catenin, transforming growth factor (TGF)-β, SMAD4, and Protein kinase B (PKB). In addition, gastric sections were stained with PAS and anti-TGF-β antibodies.Results Investigation GU micro-images revealed degeneration in both surface cells and glandular epithelial cells, which was improved by genistein. In addition, treatment with genistein significantly reduced the expression of Wnt, β-catenin, TGF-β, SMAD4, and PKB.Conclusion Besides antioxidant activity, genistein improves experimentally induced GU in rats, at least in part, via reduction of gastric tissue fibrosis as indicated by reduction in expression of Wnt, β-catenin, TGF-β, SMAD4, and PKB
