Article Abstract

Background: Anti-cancer agents are known to be toxic, leading to a number of adverse drug reactions (ADRs). ADRs not only increase the financial burden on the patient/healthcare system but also decrease the quality of life. Understanding the burden of ADR will help strengthen the knowledge on patient safety and implement intervention strategies to reduce it.

Objectives: The objectives of the study are as follows: 1. To study the pattern of adverse drug reactions of anticancer agents of patients admitted in the oncology ward. 2. To assess the causality, severity, and preventability of the adverse drug reactions observed.

Methods: This was a cross-sectional, observational study carried out in 200 adult patients in the daycare center for chemotherapy. Details of ADRs noted in the previous and current cycles were noted. Causality assessment was done using Naranjo and WHO scales. For severity and preventability assessment, Hartwig Siegel and Modified Schumock Thorton scale were used, respectively.

Results: Out of the total 732 ADRs encountered, alopecia was the most common ADR. The average number of ADRs observed per patient was 3.66 + 1.59 (mean + SD). The maximum number of ADRs were seen in Paclitaxel-carboplatin 3 weekly regimen. Nausea and alopecia were the most common ADRs reported with most regimens. On causality assessment, 95 (12.97%) were definitely related according to Naranjo's Causality scale, while 15.71% were certainly related according to the WHO scale. Of all the ADRs recorded, 47.81% were of moderate intensity, while 52.18% were of mild intensity. The majority of ADRs, i.e., 87.59%, were not preventable.

Conclusion: Alopecia was the most common ADR reported. Most of the ADRs could be causally related to drugs. These ADRs were mild to moderate in severity and were not preventable. There is a need to identify the underlying factors that predispose patients to these ADRs and target them in future research.

In recent years, there has been a significant increase in minors with gender dysphoria (GD) seeking transition treatments, including puberty blockers and cross-sex hormones. The developing child's brain exhibits structural and functional differences in children with GD compared to cisgender children, particularly in areas where sex differences exist. Brain development during childhood and adolescence is strongly influenced by sex hormones.

Introduction: The alarming rate of drug-resistant tuberculosis (DR-TB) globally is a threat to treatment success among positive tuberculosis (TB) cases. Studies aimed at determining the prevalence, trend of DR-TB and socio-demographic and clinical risk factors contributing to DR-TB in the four regions of Ghana are currently unknown. This study sought to determine the prevalence and trend of DR-TB, identify socio-demographic and clinical risk factors that influence DR-TB, and analyse the relationship between underweight and adverse drug reactions and treatment outcomes among DR-TB patients in four regions of Ghana.

Background: Lower extremity arterial disease is a prevalent vascular condition leading to ischemic symptoms and increased risk of cardiovascular events. Drug-eluting stents have improved outcomes by reducing restenosis, with sirolimus emerging as a promising alternative to paclitaxel due to its safer profile. This study evaluates the efficacy and safety of novel polymer-free Amphilimus formulation (Sirolimus + fatty acid) eluting self-expanding stent in the treatment of femoropopliteal disease in a real-world population.
