Do Primary Care Doctors Behave the Same in Antibiotic Prescribing for Upper Respiratory Tract Infections?

Purpose: To compare the extent of using an evidence-based approach in managing upper respiratory tract infections (URTIs) among primary care doctors from two different government clinic settings in Malaysia. Method: This is a cross sectional, prospective study carried out in a teaching university primary care centre in Kuala Lumpur (KL) where doctors are constantly exposed to continuing medical education (CME) and seven health clinics in Seremban, Malaysia where doctors have less exposure to CME in the year 2000. Twelve primary care practitioners in KL and 13 in Seremban participated in the study. Each practitioner was asked to record clinical data and prescriptions given to twenty consecutive patients with URTIs using a structured questionnaire for each patient. The extent of usage of an evidence-based approach in managing URTIs among practitioners was assessed

Reliability training

Discussed here is failure physics, the study of how products, hardware, software, and systems fail and what can be done about it. The intent is to impart useful information, to extend the limits of production capability, and to assist in achieving low cost reliable products. A review of reliability for the years 1940 to 2000 is given. Next, a review of mathematics is given as well as a description of what elements contribute to product failures. Basic reliability theory and the disciplines that allow us to control and eliminate failures are elucidated

Beginning Teachers’ Perceptions of their Pedagogical Knowledge and Skills in Teaching: A Three Year Study

The purpose of this paper is to investigate the beginning teachers’ perceptions of pedagogical knowledge and skills in teaching in Singapore. Data was collected from the beginning teachers at three time points: the exit point of the teacher education programme, the end of their first year and third year of teaching. In this three year study, the focus is to examine the beginning teachers’ perceptions of their development in the following teaching related factors: lesson planning, classroom management and instructional strategies. The results showed that beginning teachers’ pedagogical knowledge and skills increased significantly, but at different rates, in all three factors at the end of their third year of teaching. It suggested that learning to teach is an on-going process that begins from the pre-service teacher education programme and continues into the initial three years of teaching

Profiling of Substrate Specificities of 3C-Like Proteases from Group 1, 2a, 2b, and 3 Coronaviruses

BACKGROUND: Coronaviruses (CoVs) can be classified into alphacoronavirus (group 1), betacoronavirus (group 2), and gammacoronavirus (group 3) based on diversity of the protein sequences. Their 3C-like protease (3CL(pro)), which catalyzes the proteolytic processing of the polyproteins for viral replication, is a potential target for anti-coronaviral infection. METHODOLOGY/PRINCIPAL FINDINGS: Here, we profiled the substrate specificities of 3CL(pro) from human CoV NL63 (group 1), human CoV OC43 (group 2a), severe acute respiratory syndrome coronavirus (SARS-CoV) (group 2b) and infectious bronchitis virus (IBV) (group 3), by measuring their activity against a substrate library of 19 × 8 of variants with single substitutions at P5 to P3' positions. The results were correlated with structural properties like side chain volume, hydrophobicity, and secondary structure propensities of substituting residues. All 3CL(pro) prefer Gln at P1 position, Leu at P2 position, basic residues at P3 position, small hydrophobic residues at P4 position, and small residues at P1' and P2' positions. Despite 3CL(pro) from different groups of CoVs share many similarities in substrate specificities, differences in substrate specificities were observed at P4 positions, with IBV 3CL(pro) prefers P4-Pro and SARS-CoV 3CL(pro) prefers P4-Val. By combining the most favorable residues at P3 to P5 positions, we identified super-active substrate sequences 'VARLQ↓SGF' that can be cleaved efficiently by all 3CL(pro) with relative activity of 1.7 to 3.2, and 'VPRLQ↓SGF' that can be cleaved specifically by IBV 3CL(pro) with relative activity of 4.3. CONCLUSIONS/SIGNIFICANCE: The comprehensive substrate specificities of 3CL(pro) from each of the group 1, 2a, 2b, and 3 CoVs have been profiled in this study, which may provide insights into a rational design of broad-spectrum peptidomimetic inhibitors targeting the proteases

Benefits and challenges of electronic prescribing for general practitioners and pharmacists in regional Australia

Objective: To explore the benefits and challenges of electronic prescribing (e-prescribing) for general practitioners (GPs) and pharmacists in regional New South Wales (NSW). Methods: This qualitative study utilised semistructured interviews conducted virtually or in-person between July and September 2021. Setting and Participants: General practitioners and pharmacists practising in Bathurst NSW. Main Outcomes: Self-reported perceived and experienced benefits and challenges of e-prescribing. Results: Two GPs and four pharmacists participated in the study. Reported benefits of e-prescribing included improvement in the prescribing and dispensing process, patient adherence, and prescription safety and security. The increased convenience for the patients was appreciated particularly during the COVID-19 pandemic. Challenges discussed were how the system was perceived to be unsafe and insecure, costs of messaging and updating general practice software, utilisation of new systems and patient awareness. Pharmacists reported the need for education to patients and staff to minimise the impact of inexperience with the novel technology on workflow efficacy. Conclusion: This study provided first insight and information on the perspectives of GPs and pharmacists 12 months after the implementation of e-prescribing. Further nationwide studies are required to consolidate these findings; provide comparisons with the system's progress since conception; determine whether metropolitan and rural health care professionals share similar perspectives; and shed light on where additional government support may be required
