Antibiotic use amongst pregnant women in a public hospital in KwaZulu-Natal
Background: Antibiotics are amongst the more frequently prescribed medicines in pregnant women and the use of antibiotics is increasing. However, with limited studies available in this population, the safe use of antibiotics in pregnancy remains a concern.
Aim: To evaluate the use of antibiotics amongst pregnant women attending a public health care facility. The main objective of this study was to quantify the types of antibiotics used in pregnant women.
Setting: A public hospital classified as a referral hospital located in Durban, KwaZulu-Natal.
Methods: Demographic and treatment information of women were collected retrospectively from January 2019 to July 2019. A total of 184 pregnant patients, who received antibiotic therapy, were included in this study. Descriptive and analytical measures were used to analyse both patient demographics and treatment variables.
Results: A total of 416 antibiotic prescriptions, issued to 184 patients, were reviewed. Penicillins (39.7%), macrolides (13.0%) and combination penicillin- and beta-lactam inhibitors (12.3%) were reported as the most commonly prescribed antibiotics. Rifamycin (2.9%), hydrazides (2.2%) and aminoglycosides (1.9%) were less frequently prescribed. Most antibiotics were prescribed for diseases of the circulatory system (36.1%).
Conclusion: Several classes of antibiotics were used in pregnancy despite the lack of available safety data and clinical evidence. Informing women of the potential side effects and keeping abreast with new information played an important role in the safe, rational and effective use of medicines that contributed to improving maternal health
Complementary medicines: When regulation results in revolution
Medicines have evolved over time and so has the realisation of the importance of quality control and regulatory processes. The regulatory practices include all the steps from the development and manufacture of the active ingredients until the medicines reach the consumer. The Medicines Control Council (MCC) is mandated to regulate medicines in South Africa. Complementary medicines were previously perceived to be unregulated, although the Medicines Act does not distinguish between allopathic and complementary medicine. As the era of unregulated complementary medicine ended, the requirements in terms of dossier content left many role-players at odds. However, the MCC has a mandate to ensure that the registration of a medicine is in the interest of the public and that complementary medicine is manufactured in a facility adhering to good manufacturing practice, according to which efficacy and safety are supported by reliable data with a known shelf-life
Assessing Knowledge of Community Pharmacists on Cancer: A Pilot Study in Ghana
Background: GLOBOCAN estimates that 16,600 cases of cancer occur annually in Ghana. Community pharmacists are the first point of contact to the public due to their accessibility, wide spread and credibility. They are often looked upon to provide first aid and treatment of common illness. They provide health information and support on diseases, e.g., cancer. Their role also extends to the patients' relatives. Thus, the level of knowledge and awareness of community pharmacists are of paramount importance in order to assure best healthcare advice is provided to the public. Goals of this pilot study were; (1) to collect a preliminary data on knowledge of risk factors, signs, and symptoms of cancer, (2) to ascertain the adequacy of the research survey in determining their level of knowledge, (3) to assess the viability of a full-scale study on community pharmacists.Methods: A cross-sectional survey was conducted using a self-administered questionnaire to assess the knowledge of signs and symptoms and risk factors of cancer among 150 community pharmacists.Key Findings: Score for knowledge on cancer among community pharmacists indicated that 76.7% had poor knowledge. Responses of community pharmacists toward a list of warning signs and symptom of cancer indicated poor level of knowledge (82%). Community pharmacists recorded poor level of knowledge (65.3%) on causes and risk factors for cancer. Correlation analysis shows that age has a relation with level of knowledge on signs and symptoms of cancer.Conclusion: This pilot study provided a valuable data which indicated that community pharmacists in Ghana have poor level of knowledge on cancer. The findings obtained from the study agree with findings of other studies conducted in this area which suggest that survey instrument was adequate to assess the knowledge level of community pharmacist in Ghana. Though the response was low, data obtained indicate a viability and need of conducting a full-scale research in this workforce to get a better assessment of the level of knowledge of community pharmacists on cancer in Ghana
The market dynamics of selective serotonin re-uptake inhibitors: a private sector study in South Africa
Objective: The objective of this study was to analyse the market share of generic vs originator selective serotonin re-uptake inhibitors (SSRIs), and also compare market share of different SSRIs in the private health care sector in South Africa, over a period of 4 years.Methodology: This was a retrospective, descriptive study that measured generic market volume as a percentage of the total private SSRI market volume. Retail private sector sales data for six SSRIs available in the private sector in South Africa was evaluated. Sales data were obtained from various stages in the pharmaceutical supply chain, June 2009 – May 2013.Results: Generics constituted 86% and originators 14% of the private sector market volume of SSRIs. The share of the market volume of generic medicines increased by 29.93% over this 4-year period, while an overall increase of 27.86% in the ratio of generics to originators was observed.Conclusion: In line with policies, generic SSRIs hold a larger volume of the market in the private sector in South Africa. Keywords: Selective serotonin, private sector, South Africa
Challenges and innovations brought about by the Covid-19 pandemic regarding medical and pharmacy education especially in Africa and implications for the future
Background: Multiple measures introduced early to restrict COVID-19 have dramatically impacted the teaching of medical and pharmacy students, exacerbated by the lack of infrastructure and experience with e-learning at the start of the pandemic. In addition, the costs and reliability of the Internet across Africa pose challenges alongside undertaking clinical teaching and practical programmes. Consequently, there is a need to understand the many challenges and how these were addressed, given increasingly complex patients, to provide future direction. Method: An exploratory study was conducted among senior-level medical and pharmacy educators across Africa, addressing four key questions, including the challenges resulting from the pandemic and how these were dealt with. Results: Staff and student members faced multiple challenges initially, including adapting to online learning. In addition, concerns with the lack of equipment (especially among disadvantaged students), the costs of Internet bundles, and how to conduct practicals and clinical teaching. Multiple activities were undertaken to address these challenges. These included training sessions, developing innovative approaches to teaching, and seeking ways to reduce Internet costs. Robust approaches to practicals, clinical teaching, and assessments have been developed. Conclusions: Appreciable difficulties to teaching arising from the pandemic are being addressed across Africa. Research is ongoing to improve education and assessments
The involvement of nitric oxide in a rodent model of post-traumatic stress disorder
Thesis (Ph.D. (Pharmacology))--North-West University, Potchefstroom Campus, 2004.Post-traumatic stress disorder (PTSD), an anxiety disorder, may develop after
experiencing or witnessing a severe traumatic event. Characteristic symptoms
include hyper arousal and amnesic symptoms, while volume reductions in the
hippocampus of these patients appear correlated with illness severity and the
degree of cognitive deficit. Stress-induced increases in plasma cortisol have been
implicated in this apparent atrophy of the hippocampus, although, clinical studies
have described a marked suppression of plasma cortisol in PTSD. Given this
hypocortisolemia, the basis for hippocampal neuro degeneration and cognitive
decline remains unclear.
While stress-related hippocampal structural changes have been linked to the
neurotoxic effects of glucocorticoids and glutamate. NMDA-NO pathways have
been found to play a causal role in anxiety-related behaviours.
Prior exposure to trauma is an important risk factor for PTSD. In most instances the
disorder becomes progressively worse over time, possibly with a delayed onset,
suggesting a role for sensitization. In this study a time-dependent sensitization
(TDS) model was used to induce PTSD-like sequelae in male Spraque-Dawley rats.
The TDS-model is based on exposure to acute stressors, with a reminder of the
trauma, in the form of re-exposure to one of the acute stressor, seven days later.
NOS-activity, NMDA receptor parameters (Bmax and Kd) and GABA levels in the
hippocampus of rats, as well as plasma corticosterone levels were determined 21
days after exposure to the TDS-model.
Increased levels of corticosterone were measured after exposure to acute stress,
but these levels were found to decrease below basal levels 21 days after the re-exposure,
thus mimicking glucocorticoid levels in patients with PTSD. These
findings may also imply that the increase in glucocorticoid levels after stress
exposure is only the initial step in a cascade of events leading to neuronal
damage in the hippocampus.
This study also found that stress-restress evoked a long-lasting increase in
hippocampal NOS activity that was accompanied by a reactive down-regulation
of hippocampal NMDA receptors and dysregulation of inhibitory GABA pathways.
Subsequently, animals were chronically treated with certain pharmacological
agents prior to exposure to the TDS-model to determine possible approaches for
inhibiting the induction of PTSD. Pre-treatment with fluoxetine, currently indicated
in the treatment of PTSD. and the nNOS inhibitor, 7-nitroindazole, had no effect on
the increased NOS activity measured 21 days afler exposure to the TDS-model.
Pre-treatment with the iNOS inhibitor, aminoguanidine, however, resulted in
inhibition of the observed increase in hippocampal NOS-activity, implicating a
possible role for the iNOS isoform in the etiology of PTSD.
Treatment with ketoconazole, an inhibitor of glucoccfticoid synthesis, resulted in
inhibition of the increase in NOS-activity observed after exposure to TDS-stress, thus
indicating a possible link between stress glucocorticoid-release and NO synthesis.
These perturbations may have importance in explaining the increasing evidence
for stress-related hippocampal degenerative pathology and cognitive deficits
seen in patients with PTSD. Uncovering and understanding the role of NO in PTSD
will hopefully lead to the development of selective therapeutic agents in disorders
like PTSD. as well as providing a better understanding of basic processes
underlying normal and pathological neuronal functions in PTSD.Doctora
Knowledge and Perceptions of Adverse Events Following Immunization among Healthcare Professionals in Africa: A Case Study from Ghana
The spontaneous reporting of suspected adverse events following immunization (AEFI) by healthcare professionals (HCPs) is vital in monitoring post-licensure vaccine safety. The main objective of this study was to assess the knowledge and perceptions of AEFIs among healthcare professionals (HCPs) in Africa, using the situation in Ghana as a case study. The study was of a cross-sectional quantitative design, and was carried out from 1 July 2017 to 31 December 2017 with doctors, pharmacists, and nurses as the study participants. A 28-item paper-based questionnaire, delivered by hand to study participants, was the data collection tool in the study. The study was conducted in 4 hospitals after ethical approval was granted. The desired sample size was 686; however, 453 consented to partake in the study. Data were analyzed using SPSS (software version 22, IBM, Armonk, NY, USA), and chi-square and binary logistic regression tests were used for tests of association between HCPs’ characteristics and their knowledge and perceptions. Detailed knowledge of AEFIs was ascertained with a set of 9 questions, with 8 or 9 correctly answered questions signifying high knowledge, 5 to 7 correctly answered questions signifying moderate knowledge, and below 5 correctly answered questions signifying low knowledge. A set of 10 questions also ascertained HCPs’ positive and negative perceptions of AEFI. Results revealed that knowledge of AEFIs was high in 49 (10.8%) participants, moderate in 213 (47.0%) participants, and low in 191 (42.2%) participants. There was no statistically significant correlation between AEFI knowledge and professions. The highest negative perception was the lack of desire to learn more about how to diagnose, report, investigate, and manage AEFI, whereas the lowest was the lack of belief that surveillance improves public trust in immunization programs. There was a general awareness of AEFIs among HCPs in this study. However, negative perceptions and the lack of highly knowledgeable HCPs regarding AEFIs were possible setbacks to AEFI diagnosis, management, prevention, and reporting. More training and sensitization of HCPs on AEFIs and vaccine safety will be beneficial in improving the situation. Future research should focus on assessing the training materials and methodology used in informing HCPs about AEFIs and vaccine safety

Cancer awareness among community pharmacist: a systematic review
Abstract Background The WHO recognises that community pharmacists are the most accessible healthcare professionals to the general public. Most patients regularly visit community pharmacies for health information and also seek advice from pharmacists with respect to signs and symptoms of cancer. As readily accessible health care professionals, community pharmacists are also in the best position to include cancer-screening initiatives into their practice. Pharmacists are therefore in a good position to raise awareness when they counsel people who buy over-the-counter medication for the control of possible cancer-related symptoms. The aim of this review was to critically appraise evidence gathered from studies that; (1) explore or assess knowledge of community pharmacist on signs and symptoms of cancer, (2) explore or assess knowledge of community pharmacist on cancer screening. Methods EMBASE (ovid), CINAHL (EBSCOhost) and MEDLINE (EBSCOhost) were systematically searched for studies conducted between 2005 to July 2017. Studies that focused on knowledge of community pharmacist in cancer screening, signs and symptoms were included. Results A total of 1538 articles were identified from the search, of which 4 out of the 28 potentially relevant abstracts were included in the review. Findings of the selected studies revealed lack of sufficient knowledge on breast cancer screening, signs and symptoms. Both studies attributed knowledge limitation as the cause of reason for the key findings of their studies. Conclusion The selected studies focused largely on breast cancer, which hinder the generalizability and transferability of the findings. Hence there is a need for more studies to be conducted in this area to draw a better conclusion
