Community pharmacist intervention in doxycycline self-medication for acne among pregnant women in Saudi Arabia.

Introduction: Self-medication during pregnancy remains a prevalent global phenomenon, with pregnant women often relying on their own judgment to manage symptoms. Objective: This study aimed to assess community pharmacist practice regarding self-medication requests for acne treatment in pregnant women within Saudi Arabia. Methods: A descriptive, observational cross-sectional study was conducted in Riyadh, Saudi Arabia. Community pharmacists completed a questionnaire after interacting with a simulated customer (SC) seeking doxycycline for a pregnant woman. Data were analyzed using SPSS software. Results: One hundred community pharmacists participated in the study. The majority were between 25 and 35 years old (56 %) and worked in chain pharmacies (81 %). Notably, 71 % requested a prescription before dispensing any medication. While 66 % advised the SC to consult a physician or dermatologist, only 15 % inquired about the pregnancy and related information of the SC's sister. Conclusion: This study suggests a positive trend in community pharmacy practice regarding self-medication requests during pregnancy. However, further improvement is needed, particularly in terms of in-depth inquiry about pregnancy status and potential risks associated with specific medications. Collaborative efforts between the Ministry of Health (MOH), Saudi Food and Drug Administration (SFDA), and pharmacy education programs are crucial to minimize inappropriate dispensing practices and ensure optimal patient safety.

Novel saccharin analogs as promising antibacterial and anticancer agents: synthesis, DFT, POM analysis, molecular docking, molecular dynamic simulations, and cell-based assay.

Saccharine is a pharmacologically significant active scaffold for various biological activities, including antibacterial and anticancer activities. Herein, saccharinyl hydrazide (1) was synthesized and converted into 2-[(2Z)-2-(1,1-dioxo-1,2-dihydro-3H-1λ6,2- benzothiazole-3-ylidene) hydrazinyl] acetohydrazide (5), which was employed as a key precursor for synthesizing a novel series of small molecules bearing different moieties of monosaccharides, aldehydes, and anhydrides. Potent biological activities were found against Staphylococcus and Escherichia coli , and the results indicated that compounds 6c and 10a were the most active analogs with an inhibition zone diameter of 30-35 mm . In cell-based anticancer assay over Ovcar-3 and M-14 cell lines, compound 10a was the most potent analog with IC50 values of 7.64 ± 0.01 and 8.66 ± 0.01 µM, respectively. The Petra Orisis Molinspiration (POM) theoretical method was used to calculate the drug score of tested compounds and compare them with their experimental screening data. Theoretical DFT calculations were carried out in a gas phase in a set of B3LYP 6-311G (d,p). Molecular docking studies utilizing the MOE indicated the best binding mode with the highest energy interaction within the binding sites. The molecular docking for Ovcar-3 was carried out on the ovarian cancer protein (3W2S), while the molecular docking for M-14 melanoma was carried out on the melanoma cancer protein (2OPZ). The MD performed about 2ns simulations to validate selected compounds' theoretical studies.

Job Motivation and Satisfaction Among Female Pharmacists Working in Private Pharmacy Professional Sectors in Saudi Arabia.

Background: Pharmacists' job satisfaction has been of interest for many years and is of great importance in several respects, such as productivity and ultimately organizational performance. Objective: This study aimed to investigate the perceived motivational factors and levels of job satisfaction of female pharmacists working in private pharmaceutical sectors. Methods: This was a cross-sectional study using a web-based survey of randomly selected female pharmacists working in different private settings including community pharmacies, pharmaceutical companies, private hospitals, and other private sectors using a pre-validated satisfaction scale (Warr-Cook-Wall scale). Results: A total of 232 female pharmacists participated in the study with a mean age of 26.1±2.4 years. Of the total respondents, more than half (58%) worked for pharmaceutical companies, 25% worked in community pharmacies, and 16.8% were from hospital pharmacies. The most attractive motivating factors that encourage female pharmacists toward better performance were having the opportunity to learn new skills, being in contact with people both locally and internationally, gaining a sense of achievement, and being recognized, appreciated, and rewarded. The participants of this study were shown to have a moderate job satisfaction level. Conclusion: This study revealed that the non-Saudi, part-time pharmacists who never expected a promotion were less satisfied than the Saudi, full-time employees who expected a promotion within a year.

Assessing Outpatients' Knowledge, Attitude, and Practice Toward Managing Diabetes in Saudi Arabia.

INTRODUCTION: When it comes to non-communicable diseases like diabetes, inadequate knowledge, attitude, and practice are often linked to poor health outcomes. This study aims to assess the patients' knowledge, attitude, and practice (KAP) of diabetes in the outpatient department of a university teaching hospital in Saudi Arabia. METHODOLOGY: In this cross-sectional study, diabetes type 2 patients attending outpatient departments at a university teaching hospital, Riyadh, were assessed regarding their knowledge, attitude, and practice toward diabetes using a validated KAP scale. Descriptive and inferential analysis was done to determine the factors associated with KAP score using SPSS version 26.0 software (SPSS Inc., Chicago, IL, U.S.). RESULTS: Males made up 69.7% of the sample (n = 165), while 56.9% were between the ages of 41 and 75. The level of knowledge and practice had "good" in 37.6%, and 47.9%, respectively, but level of attitude had "positive" in 30.9% of patients. The association between knowledge tier and gender (p0.014) and insurance status (p0.008), respectively, was shown to be significant. However, the attitude tier was only significantly associated with gender (P = .003). The practice tier also showed a significant age association (P = .049). As regards, the mean scores for diabetes-related knowledge were higher only among insured participants (P = .03) than for other participants' sociodemographic factors. Meanwhile, the mean attitude scores were also higher among males (P = .006) than for other sociodemographic characteristics. A comparison of the participants' sociodemographic characteristics found no statistically significant variations in practice scores. CONCLUSION: Unfortunately, this study found that outpatient diabetes patients had insufficient knowledge, practice, and a negative attitude toward diabetes type 2. This imposes a great burden on healthcare workers and hence the healthcare system to improve patient scores via diabetes education programs or pharmacist-led patient counseling initiatives.

Community Pharmacists' Knowledge, Willingness, and Readiness to Prescribe Oral Contraceptives in Saudi Arabia.

Background: The role of community pharmacists (CPs) in various healthcare settings is well documented in the literature including providing safe and easy access to medications. Oral contraceptives (OCPs) are the most frequently used method of terminating unwanted pregnancies worldwide. Objective: This study aims to evaluate the Community pharmacist's knowledge, willingness, and readiness to prescribe OCPs in Saudi communities in Saudi Arabia. Methods: This is across sectional, self-administered questionnaire-based study conducted between May and November 2021 in the central region of Saudi Arabia. The results were presented as frequencies and percentages. Chi-square tests were used to sort significant association between groups. Results: Out of 368 CPs who got the questionnaire, 347 completed (94.3%). Most of CPs were be-tween the ages of 25 and 35, with 76.9% working in chain pharmacies. Of the surveyed CPs, 45.5% had >24 months of experience in community pharmacies. 41.8% of them prescribed more than six prescriptions for OCPs/week. The patients' safety (77.2%), physician's resistance (54.5%), and CPs objection based on religious purposes (36.9%) and lack of time (29.7%) were the most commonly cited barriers among CPs. CPs who worked in chain pharmacies were significantly too busy (p = 0.038) to prescribe OCPs. Also, community pharmacists with experience of more than two years significantly agreed not to prescribe OCPs due to religious convictions (p = 0.009). Conclusion: The current study revealed that most of the CPs were knowledgeable about OCPs. Additionally, most of them were likely to prescribe oral contraceptives. We further suggest overcoming the barriers associated with contraceptives among CPs and providing sufficient training to improve the oral contraceptive prescriptions in CPs is needed.

Cost Effectiveness of ACEIs/ARBs versus Amlodipine Monotherapies: A Single-Center Retrospective Chart Review.

The aim of this retrospective chart review study was to examine the cost effectiveness of angiotensin-converting enzyme inhibitors (ACEIs); angiotensin receptor blockers (ARBs); and dihydropyridine calcium channel blockers (CCBs) such as amlodipine, monotherapies in the management of essential hypertension among adult patients (≥18 years) without cancer, cardiovascular disease, and chronic kidney disease in the primary care clinics of a university-affiliated tertiary care hospital. Patients were followed up for at least 12 months from the initiation of therapy. Propensity score bin bootstrapping with 10,000 replications was conducted to generate the 95% confidence intervals (CI) for both treatment outcome (e.g., reduction of the systolic (SBP) and diastolic blood pressures (DBP) in mmHG) and the cost (e.g., costs of drugs, clinic visits, and labs in Saudi riyals (SAR)). Among the 153 included patients who met the inclusion criteria, 111 patients were on ACEIs/ARBs, while 44 patients were on amlodipine. On the basis of the bootstrap distribution, we found that the use of ACEIs/ARBs was associated with an incremental reduction of SBP of up to 4.46 mmHg but with an incremental cost of up to SAR 116.39 (USD 31.04), which results in an incremental cost effectiveness ratio (ICER) of SAR 26.09 (USD 6.95) per 1 mmHg reduction with 55.26% level of confidence. With regard to DBP, ACEIs/ARBs were associated with an incremental reduction of DBP of up to 5.35 mmHg and an incremental cost of up to SAR 144.96 (USD 38.66), which results in an ICER of SAR 27.09 (USD 7.23) per 1 mmHg reduction with 68.10% level of confidence. However, ACEIs/ARBs were less effective and costlier than amlodipine in reducing SBP and DBP with 44.74% and 31.89% levels of confidence, respectively. The findings of this study indicate that the use of ACEI or ARB as a monotherapy seems to be more effective than amlodipine monotherapy in the management of essential hypertension in primary care settings with minimal incremental cost.

The relationship between trust in primary healthcare providers among patients with diabetes and levels of depression and anxiety.

BACKGROUND: Trust in healthcare providers has been shown to improve several clinical and patient-reported outcomes. However, its relationship with depression and anxiety has not been investigated among patients with chronic health conditions, such as diabetes. Therefore, the aim of this study was to examine whether trust in primary care physicians among patients with diabetes is associated with their levels of depression and/or anxiety. METHOD: Adult patients (≥18 years) with a diagnosis of diabetes, confirmed through their electronic health records, were recruited and interviewed from the primary care clinics of three public hospitals. Patient trust in primary care physicians was assessed using the Health Care Relationship (HCR) Trust scale. Depression and anxiety were assessed using the Patient Health Questionnaire 9-item (PHQ-9) and Generalized Anxiety Disorder 7-item (GAD-7), respectively. Two multiple linear regression analyses were conducted to examine the association of HCR-Trust scores with PHQ-9 and GAD-7 scores controlling for age, sex, Charlson comorbidity index score, education, health literacy, annual income, nationality, duration of illness, and research site. RESULTS: The number of patients who agreed to be interviewed was 367. Most of the participants were female (61.54%) and Saudi (92.86%). High HCR-Trust scores were negatively associated with PHQ-9 scores (ß = -0.18; 95% CI: -0.23 --0.13; P = < .0001), and GAD-7 scores (ß = -0.17; 95% CI: -0.22- -0.12; P = < .0001). CONCLUSIONS: Trust in primary care physicians among patients with diabetes was associated with lower levels of depression and anxiety. Therefore, healthcare providers should adopt a patient-centered care approach that fosters trust in the relationship between their patients and themselves. Further research should explore whether interventions that foster shared decision-making and trust in healthcare providers might also improve the health outcomes of patients with diabetes.

Antimicrobial resistance, mechanisms and its clinical significance.

Antimicrobial agents play a key role in controlling and curing infectious disease. Soon after the discovery of the first antibiotic, the challenge of antibiotic resistance commenced. Antimicrobial agents use different mechanisms against bacteria to prevent their pathogenesis and they can be classified as bactericidal or bacteriostatic. Antibiotics are one of the antimicrobial agents which has several classes, each with different targets. Consequently, bacteria are endlessly using methods to overcome the effectivity of the antibiotics by using distinct types of mechanisms. Comprehending the mechanisms of resistance is vital for better understanding and to continue use of current antibiotics. Which also helps to formulate synthetic antimicrobials to overcome the current mechanism of resistance. Also, encourage in prudent use and misuse of antimicrobial agents. Thus, decline in treatment costs and in the rate of morbidity and mortality. This review will be concentrating on the mechanism of actions of several antibiotics and how bacteria develop resistance to them, as well as the method of acquiring the resistance in several bacteria and how can a strain be resistant to several types of antibiotics. This review also analyzes the prevalence, major clinical implications, clinical causes of antibiotic resistance. Further, it evaluates the global burden of antimicrobial resistance, identifies various challenges and strategies in addressing the issue. Finally, put forward certain recommendations to prevent the spread and reduce the rate of resistance growth.

Optimizing Gentamicin Dosing in Pediatrics Using Monte Carlo Simulations.

Gentamicin is known to have concentration-dependent bactericidal activity, and its nephrotoxic effect is well described. We developed a population pharmacokinetic/pharmacodynamic model to optimize gentamicin dosing in pediatrics. Data were retrospectively collected for pediatric patients 1 month to 12 years of age, admitted to general pediatric wards or intensive care units and received gentamicin for suspected or proven Gram-negative infections at King Saud University Medical City, Riyadh, Saudi Arabia. A total of 306 gentamicin peak and trough concentrations sets from 107 patients were analyzed with mean (±standard deviation) patient age and weight of 4.5 ± 3.5 years and 16.7 ± 10.8 kg, respectively. Gentamicin pharmacokinetics were adequately described with a one compartment system (R = 0.82, bias = 1.75% and precision = 88% for population predictions and R = 0.94, bias = 5% and precision = 29% for individual predictions). The gentamicin pharmacokinetic parameters were as follows: volume of distribution = 8.9 L, total body clearance = 2.8 L/h for a 20-kg patient. Monte Carlo simulations showed that doses of 5-6 mg/kg/dose once daily are adequate only to treat infections with Gram-negative organisms having minimal inhibitory concentration less than 1 µg/mL. While, at minimal inhibitory concentration of 1 µg/mL, higher doses (7-8 mg/kg/dose once daily) are needed to maximize the efficacy of gentamicin. However, at minimal inhibitory concentration of 2 µg/mL, even a 10 mg/kg dose showed poor target attainment (52%). The finding of this study highlights the need to reevaluate the current breakpoints of gentamicin and also to assess the safety of higher doses of gentamicin in pediatrics.

Vitamin D status and vitamin D receptor gene polymorphism in Saudi children with acute lower respiratory tract infection.

There is a significant association exists between vitamin D deficiencies, low respiratory tract infections, and certain types of VDR gene polymorphism. Various studies are being conducted to prove any such link between the different clinical conditions due to disturbed vitamin D regulation and VDR gene polymorphisms. The present study analyzed the presence of vitamin D receptor (VDR) gene polymorphisms (ApaI and TaqI) in Saudi pediatric patient suffering from acute lower respiratory tract infection (ALRTI) cases. Fifty children (50) with ALRTI admitted at King Saud University Medical City, Riyadh/Saudi Arabia were included in addition to seventy-three (73) apparently healthy children who were considered as the control group. Genomic DNA from whole blood was extracted and subjected to polymerase chain reaction (PCR) targeting TaqI and ApaI VDR polymorphisms. RFLP-PCR genotyping was performed to determine the allelic frequency within the VDR gene. In the whole sample, the allelic frequency of ApaI polymorphism in the VDR gene was 58.5%, 17.9%, and 23.6% for AA, Aa, and aa respectively (p = 0.11), while it was 48%, 19%, and 33% for TT, Tt, and tt respectively (p = 0.33) with regards to the frequency of TaqI polymorphism in the VDR gene. VDR ApaI Aa and aa genotypes and VDR TaqI Tt and tt genotypes were not associated with increased risk of ALRTI in children (OR 0.87, 95% CI 0.33-2.28, p = 0.77; OR 0.56, 95% CI 0.23-1.4, p = 0.21; OR 1.15, 95% CI 0.44-2.99, p = 0.77; OR 0.73, 95% CI 0.32-1.68, p = 0.46 respectively). To conclude, neither vitamin D status nor VDR gene polymorphisms such as ApaI and TaqI is associated with increased susceptibility to ALRTI. Linkage disequilibrium was not detected between ApaI and TaqI VDR gene polymorphisms as in the case of serum vitamin D status in ALRTI patients versus apparent healthy children.

Use of dietary and performance-enhancing supplements among male fitness center members in Riyadh: A cross-sectional study.

This study aimed to explore the health beliefs and patterns of dietary supplement usage among fitness center members. This cross-sectional study was conducted in four large indoor fitness centers in Riyadh, Saudi Arabia. This study involved male fitness center members aged ≥18 years with no speech or hearing disabilities. In-person interviews were conducted with fitness center members who agreed to participate using a newly developed questionnaire. Information on participants' sociodemographics (e.g., age and education), smoking status, health status, exercise frequency, average time spent exercising, different supplements used, used supplements sources, and health beliefs regarding dietary supplements were obtained. A total of 445 fitness center members agreed to participate, and 198 of them reported taking dietary supplements. Most participants were between the age of 18 and 25 years (66%), had a college degree (74%), non-smokers (77%), healthy (84%), and perform exercise at least thrice weekly (52%) for at least 1 hour (63%). The percentage of participants who had favorable health views on dietary supplements was significantly higher among the supplement users than among the non-users (P<0.0001). Proteins, multivitamins, amino acids, and omega 3 fatty acids were the most commonly reported supplements used. Almost 30% of the supplement users reported buying them overseas, 28% online, 25% from a pharmacy or supplement store, 19% from a medical clinic, and 17% from peddlers. Public health campaigns are needed to educate the public on the potential harmful effects of supplements if purchased from an unofficial seller or taken without seeking medical advice before using them.

Optimizing Amikacin Dosage in Pediatrics Based on Population Pharmacokinetic/Pharmacodynamic Modeling.

OBJECTIVE: Our objective was to determine the population pharmacokinetic parameters of amikacin in pediatric patients to contribute to the future development of a revised optimum dose and population-specific dosing regimens. METHODS: We performed a retrospective chart review in non-critical pediatric patients (aged 1-12 years) who received amikacin for suspected or proven Gram-negative infection at a university hospital. The population pharmacokinetic models were developed using Monolix 4.4. Pharmacokinetic/pharmacodynamic (PK/PD) simulations were performed to explore the ability of different dosage regimens to achieve the pharmacodynamic targets. RESULTS: The analysis included 134 amikacin plasma concentrations from 67 patients with a mean ± standard deviation age of 4.1 ± 3.9 years and bodyweight of 15 ± 8.4 kg. The patients received an amikacin total daily dose (TDD) of 23 ± 7.3 mg/kg, which resulted in peak and trough concentrations of 20.65 ± 7.6 and 2.4 ± 1.7 mg/l, respectively. The estimated pharmacokinetic parameters for amikacin were 1.2 l/h and 6.5 l for total body clearance (CL) and the volume of distribution (V), respectively. Dosing simulations showed that the standard dosing regimen (15 mg/kg/day) of amikacin achieved the PK/PD target of peak serum concentration (Cpeak)/minimum inhibitory concentration (MIC) ≥ 8 for an MIC of 2 mg/l; higher doses were required to achieve higher MIC values. CONCLUSION: The simulation results indicated that amikacin 20 mg/kg once daily provided a higher probability of target attainment with lower toxicity than dosing three times daily. In addition, combination therapy is recommended for pathogens with an MIC of ≥ 8 mg/l.

Antimicrobial susceptibility of microorganisms causing Urinary Tract Infections in Saudi Arabia.

INTRODUCTION: Urinary Tract Infections (UTIs) is one of the most common infections worldwide. UTIs remain a challenge to the healthcare system because of the emergence of antimicrobial resistance. The aim of this study is to report the most common UTI-causative organisms associated with the emergence of antimicrobial resistance in Saudi Arabia. METHODOLOGY: a retrospective cross sectional study of 1918 positive urine culture samples of both gender collected over 9 months (May 2015 to February 2016) from a major tertiary hospital in Riyadh, Saudi Arabia. RESULTS: the median age of individuals involved in the study was 43 years, with males constituting 27.7% only of the population. Among cases deemed complicated (81.1%), common causes were diabetes, pregnancy, and immunocompromization, comprising 24.7%, 11.9%, and 10.8%, respectively. Escherichia coli (52%) was the most common uropathogen, followed by Klebsiella pneumoniae (15%), Pseudomonas aeruginosa (8%) Streptococcus agalactiae (Group B streptococcus) (7%), and Enterococcus faecalis (5%). Overall sensitivity studies showed the most highly resistant uropathogen was Escherichia coli (60%) followed by Klebsiella pneumoniae (16%), Pseudomonas aeruginosa (4%) Enterococcus faecalis (3%), and Enterobacter cloacae (2%). Concerning the first defense antibiotics prescribed for UTI, E. coli was most frequently resistant to Sulfamethoxazole/Trimethoprim (47%) followed by ciprofloxacin (34%). K. pneumoniae was most frequently resistant to Sulfamethoxazole/trimethoprim (35%) followed by cefuroxime (30%), while P. aeruginosa to ciprofloxacin (13%). CONCLUSION: Because of a high level of antimicrobial resistance amongst uropathogens in Saudi Arabia, the development of regional and national UTI guidelines is recommended.

Relationship between health literacy and body mass index among Arab women with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) puts patients at higher risk for obesity and diabetes. Poor health literacy is also associated with these conditions. Notably, weight loss is associated with improved ovulation and pregnancy rates for women with PCOS. In this study the association between health literacy and body mass index (BMI) among women with PCOS was examined. METHODS: The health literacy of women with PCOS was measured using the Arabic version of the single item literacy screener (SILS) at a university medical center. Sociodemographic and medical information was collected by interviewing the participants and reviewing their medical records, respectively. The relationship between health literacy and BMI was assessed by multiple logistic regression analysis. RESULTS: Health literacy was assessed in 127 women with PCOS from September 2015 to February 2016. Only 16.54% of participants had limited health literacy. The mean BMI for all participants was 30.57 (kg/m2), and the mean age was 27.40 years. Further, most of the participants (74%) had a high school diploma or a higher degree. Almost 56% of the participants were taking metformin, and 11.81% had hypothyroidism. After controlling for age, education, hypothyroidism diagnosis, and the use of metformin, participants with high BMI were 10% less likely to have a good health literacy level (OR = 0.904; 95% CI = 0.829-0.987; P = 0.0238). CONCLUSION: Improving the health literacy of patients with PCOS may have a positive impact on their BMI and eventually lead to favorable health outcomes.

The effect of metformin use on pregnancy rates among polycystic ovary syndrome patients undergoing in vitro fertilization: A retrospective-cohort study.

BACKGROUND: Metformin is widely used with gonadotropins by women with polycystic ovary syndrome (PCOS) during in vitro fertilization (IVF) to increase their chances of pregnancy. The aim of this study was to evaluate the efficacy of metformin in improving the rates of clinical pregnancy among women with PCOS undergoing IVF. METHODS: This was a retrospective cohort study of women with PCOS, aged 18-40 years, undergoing IVF during 2006-2012 at a University Hospital in Riyadh, Saudi Arabia. Baseline patient data including menstrual frequency, biochemical parameters such as fasting serum insulin (FSI) concentration, comorbidities, and the rates of ovulation and pregnancy were collected. Pregnancy rates were compared between the metformin and non-metformin groups. RESULTS: A total of 210 women with PCOS met the inclusion criteria and were included in the study. Of the 210 women with PCOS, 109 of them received metformin in addition to gonadotropins. Patients who received metformin were 16% less likely to be pregnant in comparison with those who did not receive metformin (OR = 0.840; 95% CI = 0.710-0.993; P = 0.0415), when controlled for baseline prolactin level, testosterone level, lipid panel, FSI concentration, fasting plasma glucose (FPG) concentration, comorbidities, duration of infertility, daily metformin dosage, and the previous use of clomiphene and/or leuprolide. CONCLUSIONS: Metformin co-treatment during IVF may negatively affect pregnancy rates. Further well-designed, randomized, double-blind placebo-control clinical trials are needed to confirm the findings of this study.

Shortage of psychotropic medications in community pharmacies in Saudi Arabia: Causes and solutions.

Background: Patients with mental disorders, such as depression and anxiety, who seek medical care in private psychiatric clinics in Riyadh, Saudi Arabia, have recently expressed concerns to doctors about difficulty in filling psychotropic medications, such as Amitriptyline and Aripiprazole, at retail community pharmacies. Objectives: The aim of this study was to investigate whether there is a shortage of some commonly prescribed psychotropic medications in retail community pharmacies in Saudi Arabia, and if so, to explore the possible reasons behind the shortage of these medications. Methods: The availability of 28 commonly prescribed psychotropic medications was checked in multiple retail community pharmacies in 4 different regions of Saudi Arabia. Further, potential reasons behind the shortage of some psychotropic medications in retail community pharmacies were also explored. Results: Amitriptyline, Amoxapine, Aripiprazole, Bupropion, Buspirone, Duloxetine, Haloperidol, Hydroxyzine, Lithium, Prochlorperazine, Procyclidine, Promethazine, Thioridazine, Trazodone, and Trifluoperazine were unavailable in over half of the 248 community pharmacies surveyed. Four possible reasons behind the shortage of these medications were reported by 31 pharmacists working in different retail community pharmacies' purchasing departments, with a majority (58.06%) reporting the primary reason for a shortage of these medications that they are slow-moving items with low profit margins. Conclusions: The findings of this study should expedite the reform process in both the Ministry of Health and the Saudi Food and Drug Authority (SFDA) to publish and enforce an essential list of medications for retail community pharmacies, which should include the most commonly prescribed psychotropic medications.

Ovulation induction by metformin among obese versus non-obese women with polycystic ovary syndrome.

OBJECTIVES: There is some evidence that the efficacy of metformin as an ovulation stimulation agent depends on the body mass index (BMI) of the treated anovulatory women with polycystic ovary syndrome (PCOS). The aim of this study was to examine the likelihood of successful ovulation among obese (BMI ⩾30 kg/m2) versus non-obese (BMI <30 kg/m2) women with PCOS. METHODS: A total of 243 medical charts of women with PCOS who visited King Khaled University Hospital (KKUH) in Riyadh, Saudi Arabia, between 2006 and 2012 were reviewed. Patients' sociodemographic, laboratory, and medical data were collected. Descriptive statistics and multiple logistic regression analyses were performed to compare the patients' baseline data and successful ovulation among the obese and non-obese anovulatory women with PCOS, respectively. RESULTS: One hundred and nine women with PCOS who were prescribed metformin for ⩾3 months were included in the study. Almost 60% of the women who were included in the study were obese. The likelihood of ovulation among obese women with PCOS was 77.9% (odds ratio = 0.221, 95% CI 0.052-0.947, P = 0.042) less than that in their non-obese counterparts. CONCLUSION: The findings of this study suggest that metformin is more effective as an ovulation stimulation agent when administered to non-obese women with PCOS. Lifestyle modifications such as diet and exercise should be emphasized upon as an integral part of any treatment plan for PCOS.

Metallothionein 2A expression and its relation to different clinical stages and grades of breast cancer in Egyptian patients.

OBJECTIVE: To assess the relation of blood MT-2A expression, serum zinc, copper, Cu/Zn ratio, total antioxidant status (TAS), total oxidant status (TOS) and oxidant status index (OSI) with benign and malignant breast tumors, also, their relation to different clinical stages and grades of breast cancer. MATERIAL AND METHODS: Unrelated 199 female patients with breast tumor and 120 healthy controls were enrolled in this study. Metallothionein-2A (MT-2A) expression was assessed by quantitative real-time polymerase chain reaction (RT-PCR). Serum MT-2A levels were measured by ELISA. Serum copper (Cu) and Zinc (Zn) concentrations were determined by atomic absorption spectrophotometry. Serum TOS and TAS levels were measured colorimetrically. RESULTS: Our study demonstrated that blood metallothionein-2A mRNA level, serum MT-2A, copper, Cu/Zn ratio, total oxidant status and oxidant status index were significantly increased, while, serum zinc level and total antioxidant status were significantly decreased in patients with breast cancer and benign breast disease as compared to controls and in breast cancer group as compared to the benign one. CONCLUSIONS: Blood metallothionein-2A expression and serum MT-2A levels could be important prognostic indices of less differentiated, more aggressive breast cancer phenotype. Disturbance of copper, zinc and oxidative stress status might contribute to the pathogenesis of breast tumor and could be useful biomarkers for diagnosing and monitoring such disease.
