The Approach of Pharmacy Students Towards Communication of Medication Errors in Karachi, Pakistan

Purpose: To assess pharmacy students’ knowledge of communicating medication errors in Karachi, Pakistan.Methods: The study design was cross-sectional and conducted from February to May 2014. A previously validated questionnaire was adopted, modified and distributed to final year pharmacy students in four universities of Karachi. Descriptive statistics were used to present students’ demographic information and their response to the questionnaire items. Pearson chi square test and Logistic regression model were executed to evaluate the association of gender and institution of students with their response.Results: Out of 600 survey questionnaires distributed, only 464 were returned in useable form, giving a response rate of 77.33 %. A majority of the students showed moderately positive attitude towards general communication and training in communicating medication errors. More than 40 % of the respondents were not satisfied with the training they received in communicating and reporting incidence of medication errors. Incorrect drug (14.65 %), incorrect dose (8.40 %) and improper storage of medicines (7.97 %) were the most common errors observed by the students during clerkship.Conclusion: The findings indicate the need for a more standardized approach to improving knowledge of medication errors as well as training in the communication of occurrence of medication errors.Keywords: Communication, Medication error, Pharmacy students, Standardized trainin

Factors associated with perceived stress in Middle Eastern university students.

OBJECTIVE University students face high levels of stress-related factors, such as an unfamiliar environment, challenging workload, and uncertainty about their ability to succeed. Participants: A total of 370 students in Qatar who consented to participate between February 2017 and February 2018. Methods: This cross-sectional study assessed perceived stress [using a validated 4-point perceived stress scale (PSS-4)], as well as diet, exercise, body mass index, sleep, and life satisfaction. Results: Among students aged 18-39 (mean = 20.1 ± 3.0 years), PSS-4 scores varied between 0 and 16 (mean = 7.4 ± 3.4). Elevated stress was significantly associated with female sex, country of origin, residing off-campus, eating when bored, lack of self-discipline, disturbed sleep, and low levels of life satisfaction. Furthermore, students with PSS-4 scores above the median level were 2.3 times likelier to report difficulty concentrating on academic work. Conclusion: Elevated stress levels are present in university students in Qatar. Strengthening coping skills may improve health and academic performance

Effect of lipid and cellulose based matrix former on the release of highly soluble drug from extruded/spheronized, sintered and compacted pellets

Abstract Background The study was to develop an extended release (ER) encapsulated and compacted pellets of Atenolol using hydrophobic (wax based and polymeric based) and high viscosity grade hydrophilic matrix formers to control the release of this highly water soluble drug by extrusion/spheronization (ES). Atenolol is used for cardiovascular diseases and available as an immediate release (IR) tablet dosage form. The lipids, Carnauba wax (CW), Glyceryl monostearate (GMS) and cellulose based i.e. Hydroxypropyl methylcellulose (HPMC) and Ethyl cellulose (EC) were used in preparing Atenolol ER pellets. Thermal sintering and compaction techniques were also applied to control the burst release of Atenolol. Method For this purpose, thirty-six trial formulations (F1-F36) were designed by Response Surface Methodology (RSM), using Design-Expert 10 software, keeping (HPMC K4M, K15 M & K100 M), (EC 7FP, 10FP & 100FP), waxes (GMS, & CW), their combinations, sintering temperature and duration, as input variables. Dissolution studies were performed in pH, 1.2, 4.5 and 6.8 dissolution media. Drug release kinetics using different models such as zero order, first order, Korsmeyer-Peppas, Hixon Crowell, Baker-Lonsdale and Higuchi kinetics were studied with the help of DDsolver, an excel based add-in program. Results The formulations F35 and F36 showed compliance with Korsmeyer-Peppas Super case II transport model (R2 = 0.975–0.971) in dissolution medium pH 4.5. No drug excipient interaction observed by FTIR. Stereomicroscopy showed that sintered combination pellets, (F35), were highly spherical (AR = 1.061, and sphericity = 0.943). The cross-sectional SEM magnification (at 7000X) of F34 and F35 showed dense cross-linking. The results revealed that the optimized formulations were F35 (sintered pellets) and F36 (compacted pellets) effectively controlling the drug release for 12 h. Conclusion Extended-release encapsulated, and compacted pellets were successfully prepared after the combination of lipids CW (10%) and GMS (20%) with EC (10FP 20% & 100FP 20%). Sintering and compaction, in addition, stabilized the system and controlled the initial burst release of the drug. Extended release (ER) Atenolol is an effective alternative of IR tablets in controlling hypertension and treating other cardiovascular diseases

Dietary Patterns and Associated Lifestyle Factors Among University Students in Qatar

We aimed to investigate the association between university students\u27 dietary patterns, their demographics and lifestyle in a cross-sectional study in Qatar. 370 students in eight universities in Qatar enrolled between February 2017 and February 2018. Based on a structured questionnaire, dietary patterns were identified using principal component analysis, and their associations with student characteristics were assessed using logistic regression. Four dietary patterns were identified. The \u27fast food\u27 pattern was associated with being younger and male (-values ≤ 0.1). The \u27traditional diet\u27 pattern was associated with not skipping meals or eating when bored (-values = 0.1). The \u27healthy diet\u27 pattern was associated with regular exercise and having time to eat healthy foods (-values ≤ 0.01). The \u27protein shake\u27 pattern was associated with being male and engaging in more vigorous physical activity (-values ≤ 0.01). Our findings provide a roadmap for the prioritization of population-specific interventions in university students within Qatar and the region
