Globally, the inappropriate dispensing and use of antibiotics in animals has contributed to the development of bacterial antimicrobial resistance (AMR). In Zambia, there is insufficient information among community pharmacy professionals on antibiotic use (ABU) and AMR in food-producing animals. This study assessed community pharmacy professionals’ knowledge, attitudes, and practices regarding poultry antibiotic dispensing, use, and bacterial AMR in the Lusaka district of Zambia. A cross-sectional study was conducted among 178 community pharmacy professionals between February and April 2022 using a semi-structured questionnaire. Data were analyzed using Stata version 17. Of the total participants (n = 178), 51.1% (n = 91) were pharmacists. The most dispensed antibiotic was oxytetracycline, a Watch antibiotic, mainly without prescriptions. Good knowledge of ABU and AMR was associated with work experience for more than one year (p = 0.016), while good practices were associated with male gender (p = 0.039) and work experience of more than one year (p = 0.011). The study found moderate knowledge, positive attitudes, and moderate practices of pharmacy professionals on poultry ABU and AMR. There was high dispensing of poultry antibiotics without prescriptions, which calls for strict implementation of antimicrobial stewardship and surveillance programs in poultry production in Zambia to reduce AMR.

Aim: We investigated HSP90α as screening biomarker for early colorectal cancer (CRC). Methods & results: Seventy-seven CRC patients and 78 healthy controls were enrolled. Plasma HSP90α was significantly higher in CRC patients than in healthy controls (p < 0.05). levels were higher in late (stages III and IV) CRC than in early (stages I and II) CRC (p = 0.022). HSP90α conferred an advantage in the diagnosis of early CRC. Combination of HSP90α and carcinoembryonic antigen improved the diagnostic sensitivity (84.4%) and specificity (89.5%) for CRC (area under the curve: 0.968); for early CRC, the sensitivity was 82.5% and specificity was 89.5% (area under the curve: 0.955). Conclusion: HSP90 is a potential biomarker for the diagnosis of early CRC.

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection that emerged from China in December 2019 and is caused by severe acute respiratory syndrome coronavirus 2. Due to the airborne nature of its transmission, COVID-19 spread to the rest of the world rapidly. Thus, the World Health Organization declared COVID-19 a pandemic. This paper evaluated the factors that lead to self-medication in people suffering from respiratory tract infections such as COVID-19, and the consequences of practicing self-medication using antimicrobial agents. Most of the signs and symptoms of COVID-19 are also seen in infections such as malaria, flu, and the common cold. For this reason, and also due to poor healthcare-seeking behaviour, most people tend to self-medicate using medicines that are known to be effective against malaria, common cold, and COVID-19. Among the commonly used medicines in the practice of self-medication include antibacterials, antimalarials, and antivirals. Some vitamins such as vitamin C boost the immune system enabling it to provide effective defence mechanisms against microbes. However, self-medication may pose consequences such as the emergence of antimicrobial-resistant microorganisms, hypersensitivity reactions as well as dose-dependent toxicities viz dermatoxicity, cardiotoxicity, and hepatoxicity. Infectious diseases caused by antimicrobial-resistant microbes are difficult and, in some instances, impossible to treat thereby leading to increased morbidity and mortality among infected people. Consequently, antimicrobial resistance poses another global public health problem and requires a multisectoral approach to curb. It is our recommendation that all governments ensure that there are adequate medicines and efficient human resources in healthcare facilities as well as sufficient public awareness to prevent people from seeking self-medication.

Background: Malaria continues to be a major public health problem in Malawi and the greatest load of mortality and morbidity occurs in children five years and under. However, there is no information yet regarding trends and predictions of malaria incidence in children five years and under at district hospital level, particularly at Nsanje district hospital. Aim: Therefore, this study aimed at investigating the trends of malaria morbidity and mortality in order to design appropriate interventions on the best approach to contain the disease in the near future. Methodology: Trend analysis of malaria morbidity and mortality together with time series analysis using the SARIMA (Seasonal Autoregressive Integrated Moving Average) model was used to predict malaria incidence in Nsanje district. Results: The SARIMA model used malaria cases from 2015 to 2019 and created the best model to forecast the malaria cases in Nsanje from 2020 to 2022. An SARIMA (0, 1, 2) (0,1,1)₁₂ was suitable for forecasting the incidence of malaria for Nsanje. Conclusion: The mortality and morbidity trend showed that malaria cases were growing at a fluctuating rate at Nsanje district hospital. The relative errors between the actual values and predicted values indicated that the predicted values matched the actual values well. Therefore, the model proved that it was adequate to forecast monthly malaria cases and it had a good fit, hence, was appropriate for this study

Introduction: Antifungal resistance (AFR) is a growing global public health concern. Little is currently known about knowledge, attitudes and practices regarding AFR and antifungal stewardship (AFS) in Zambia, and across the globe. To address this evidence gap, we conducted a study through a questionnaire design starting with pharmacy students as they include the next generation of healthcare professionals. Methods: A cross-sectional study among 412 pharmacy students from June 2023 to July 2023 using a structured questionnaire. Multivariable analysis was used to determine key factors of influence. Results: Of the 412 participants, 55.8% were female, with 81.6% aged between 18 and 25 years. Most students had good knowledge (85.9%) and positive attitudes (86.7%) but sub-optimal practices (65.8%) towards AFR and AFS. Overall, 30.2% of students accessed antifungals without a prescription. Male students were less likely to report a good knowledge of AFR (adjusted OR, AOR = 0.55, 95% CI: 0.31–0.98). Similarly, students residing in urban areas were less likely to report a positive attitude (AOR = 0.35, 95% CI: 0.13–0.91). Fourth-year students were also less likely to report good practices compared with second-year students (AOR = 0.48, 95% CI: 0.27–0.85). Conclusions: Good knowledge and positive attitudes must translate into good practices toward AFR and AFS going forward. Consequently, there is a need to provide educational interventions where students have low scores regarding AFR and AFS. In addition, there is a need to implement strategies to reduce inappropriate dispensing of antifungals, especially without a prescription, to reduce AFR in Zambia.

Introduction: Antimicrobial stewardship (AMS) can improve the rational use of antibiotics in hospitals. This study assessed the impact of a multifaceted AMS intervention on antibiotic use and prescribing patterns at three tertiary hospitals in Zambia. Methods: Point Prevalence Surveys (PPS) were conducted in three tertiary hospitals in August 2022 and in October 2023. It was part of a 3-year AMS demonstration project that aimed to optimize the use of antibiotics in treating urinary tract infections (UTIs) and bloodstream infections (BSIs) in various health sector settings in Zambia. Up to 170 medical records in 2022 and 265 in 2023 were included in the assessment. Results: Overall, the prevalence of antibiotic use in this PPS was 75%. Eighty-one percent (81%) and 71% of patients assessed were on at least one antibiotic in 2022 and 2023, respectively, indicating a decrease of 10%. Similarly, prescribing ceftriaxone, the most prescribed antibiotic, declined from an average of 48% in 2022 to 38% in 2023. Adherence to Standard Treatment Guidelines (STGs) slightly increased from 42% in 2022 to 45% in 2023. Additionally, antibiotic prescribing was reduced from 1.38 to 1.21. Conclusions: Antimicrobial stewardship had an early positive impact on antibiotic use and adherence to Standard Treatment Guidelines.
