RESUMEN
Antimicrobial resistance (AMR) has become more of a concern in recent decades, particularly in infections associated with global public health threats. The development of new antibiotics is crucial to ensuring infection control and eradicating AMR. Although drug discovery and development are essential processes in the transformation of a drug candidate from the laboratory to the bedside, they are often very complicated, expensive, and time-consuming. The pharmaceutical sector is continuously innovating strategies to reduce research costs and accelerate the development of new drug candidates. Computer-aided drug discovery (CADD) has emerged as a powerful and promising technology that renews the hope of researchers for the faster identification, design, and development of cheaper, less resource-intensive, and more efficient drug candidates. In this review, we discuss an overview of AMR, the potential, and limitations of CADD in AMR drug discovery, and case studies of the successful application of this technique in the rapid identification of various drug candidates. This review will aid in achieving a better understanding of available CADD techniques in the discovery of novel drug candidates against resistant pathogens and other infectious agents.

Reducing maternal and child mortality is a health priority in South Africa. Therefore, health professional education should produce graduates that can meet these needs. This study compared the maternal and child health (MCH) knowledge and skills of cohorts of final-year students exposed to a traditional (in 2017 and 2018) and integrated (2019) curriculum using a 34-item questionnaire. Between the 2019 and 2017 cohorts, ANOVA and post hoc analysis showed significant differences in the reproductive and sexual health component which was dispersed in the second and final years of study (p = 0.007, Mean Difference (MD) = 8.3) andneonatal and child care (p = 0.000, MD = 15). while it was only in maternal and antenatal care (p = 0.009, MD = 10.0) for the 2019 and 2018 cohorts. Significant differences were observed in participants' average mean scores (p = 0.000 for 2018 and 2017). The highest mean scores were recorded by the 2019 cohort in the three assessments. A one-sample t-test showed the highest mean differences in the reproductive and sexual health components (p = 0.000; MD 2017 = 12.4, MD 2018 = 14.8, MD 2019 = 20.7). Overall, the integrated MCH curriculum and the longitudinal dispersion of content enhanced students' knowledge and skills.
RESUMEN
The South African Pharmacy Council (SAPC) regulates undergraduate pharmacy education and pharmacy practice. The SAPC Good Pharmacy Practice manual describes the role of pharmacists in maternal and child health (MCH) in line with the recommendation of international health regulatory bodies. However, baseline study findings in 2017 supported literature from around the world that indicated a need for curriculum review and integration to address the knowledge and skills gap in pharmacists' MCH training. This paper describes the development and implementation of an integrated framework for MCH training across the four years of a Bachelor of Pharmacy program. The intervention included didactic lectures, skills practical on infant growth assessment, and an experiential learning component at primary health care clinics and pharmacies. Knowledge and skills assessment on contraception, maternal and antenatal care, and neonatal and child care were carried out pre, eight weeks post, and two years post intervention using the same questionnaire. ANOVA and post hoc analyses showed that participants' knowledge and skills increased post intervention but decreased significantly two years later except in contraception where students experienced longitudinal integration of the MCH component. Generally, participants performed above the university average except in maternal and antenatal care.
RESUMEN
Drug repurposing for COVID-19 has several potential benefits including shorter development time, reduced costs and regulatory support for faster time to market for treatment that can alleviate the current pandemic. The current study used molecular docking, molecular dynamics and protein-protein interaction simulations to predict drugs from the Drug Bank that can bind to the SARS-CoV-2 spike protein interacting surface on the human angiotensin-converting enzyme 2 (hACE2) receptor. The study predicted a number of peptide-based drugs, including Sar9 Met (O2)11-Substance P and BV2, that might bind sufficiently to the hACE2 receptor to modulate the protein-protein interaction required for infection by the SARS-CoV-2 virus. Such drugs could be validated in vitro or in vivo as potential inhibitors of the interaction of SARS-CoV-2 spike protein with the human angiotensin-converting enzyme 2 (hACE2) in the airway. Exploration of the proposed and current pharmacological indications of the peptide drugs predicted as potential inhibitors of the interaction between the spike protein and hACE2 receptor revealed that some of the predicted peptide drugs have been investigated for the treatment of acute respiratory distress syndrome (ARDS), viral infection, inflammation and angioedema, and to stimulate the immune system, and potentiate antiviral agents against influenza virus. Furthermore, these predicted drug hits may be used as a basis to design new peptide or peptidomimetic drugs with better affinity and specificity for the hACE2 receptor that may prevent interaction between SARS-CoV-2 spike protein and hACE2 that is prerequisite to the infection by the SARS-CoV-2 virus.

BACKGROUND: Maternal and child mortality is a global concern and one of South Africa's quadruple burdens of disease. As easily accessible frontline healthcare workers, pharmacists play an important role in the continuum of maternal and child health (MCH) care according to recommendations by international health regulatory bodies. Pharmacy schools are obliged to train pharmacy students to meet the priority health needs of the population so that graduates are 'fit for purpose'. The baseline study aimed to evaluate the knowledge and skills of 2017 final year pharmacy students who were exposed to a fragmented MCH care curriculum at a university in South Africa to inform curriculum review. METHODS: A descriptive, quantitative, non-randomized study was conducted among final year pharmacy students using a self-administered structured questionnaire. The questionnaire was designed in sections to assess participants' knowledge of reproductive and sexual health (RSH), maternal and antenatal care (MAC), neonatal and child care (NCC) and skills related to infant growth assessment procedures. Data was analysed descriptively using frequencies and percentages. A score of 50% in each section of the questionnaire indicated a pass. Participants assessed their exposure to MCH topics in the curriculum. RESULTS: Of the 89 available students, 61% consented to participate in the study. The average scores attained for each section were; 62.4% for RSH, 54.5% for MAC, 50.4% for NCC and 25.3% for infant growth assessment. The pass rate was 78% for RSH, 56% for MAC, 57% for NCC, and 19% for infant growth assessment. About 13% of the participants passed all the knowledge and the skills sections. Age, gender, being a parent or doing locums did not have any influence on participants' performance. Participants reported that they had more on-campus curriculum content exposure to RSH compared to other MCH care topics. CONCLUSION: Final year pharmacy students showed adequate knowledge of RSH with adequate curriculum exposure. Average knowledge of MAC, NCC and poor skills in infant growth assessment which corresponded to curriculum exposure was observed. The results suggest the need for improvement in the current curriculum in the affected areas to adequately equip students to render desirable services.
