RESUMO

Magnetic Resonance Imaging (MRI) employs a radiofrequency electromagnetic field to create pictures on a computer. The prospective biological consequences of exposure to radiofrequency electromagnetic fields (RF EMFs) have not yet been demonstrated, and there is not enough evidence on biological hazards to offer a definite response concerning possible RF health dangers. Therefore, it is crucial to research the health concerns in reaction to RF EMFs, considering the entire exposure in terms of patients receiving MRI. Monitoring increases in temperaturein-vivothroughout MRI scan is extremely invasive and has resulted in a rise in the utilization of computational methods to estimate distributions of temperatures. The purpose of this study is to estimate the absorbed power of the brain exposed to RF in patients undergoing brain MRI scan. A three-dimensional Penne's bio-heat equation was modified to computationally analyze the temperature distributions and potential thermal effects within the brain during MRI scans in the 0.3 T to 1.5 T range (12.77 MHz to 63.87 MHz). The instantaneous temperature distributions of thein-vivotissue in the brain temperatures measured at a time, t = 20.62 s is 0.2 °C and t = 30.92 s is 0.4 °C, while the highest temperatures recorded at 1.03 min and 2.06 min were 0.4 °C and 0.6 °C accordingly. From the temperature distributions of thein-vivotissue in the brain temperatures measured, there is heat build-up in patients who are exposed to electromagnetic frequency ranges, and, consequently, temperature increases within patients are difficult to prevent. The study has, however, indicated that lengthier imaging duration appears to be related to increasing body temperature.

RESUMO

This study examined the impact of advance care planning (ACP) on the quality of life for patients with chronic kidney disease (CKD) at Komfo Anokye Teaching Hospital in Ghana. It specifically investigated patients' perspectives on their readiness for ACP. Utilizing a qualitative descriptive design, one-on-one interviews were conducted with CKD patients at the renal clinic, employing a semi-structured interview guide for thematic analysis of audio data. The findings revealed a gap in understanding among CKD patients, with participants acknowledging their vulnerability to renal failure, often linked to a medical history of diabetes and hypertension. Despite recognizing potential outcomes such as dialysis dependency or death, some patients retained hope for a cure, relying on faith. The initial kidney failure diagnosis induced shock and distress, leading many patients to prefer the comfort and familiarity of home-based care, including dialysis. Meanwhile, a minority favored hospital care to protect their children from psychological trauma. Most patients deemed legal preparations unnecessary, citing limited assets or a lack of concern for posthumous estate execution. These insights emphasize the necessity for targeted education and support in ACP to enhance patient outcomes in chronic kidney disease care and end-of-life planning.

RESUMO

In this study, we attempted to move beyond the skewed discussions on stigma to unravel other social consequences that are experienced by persons who have recovered from COVID-19. We conducted a documentary review of published news reports from 14 highly ranked news portals in Ghana and Malaysia (published between 1st January 2020 and 30th August 2020) that contained personal accounts from the recovered patients about their lived experiences with the virus and social consequences encountered after recovery. Narratives from the recovered patients were extracted and analyzed following the narrative thematic analysis procedure. Common themes identified from the narratives included: 1) Stigma impacting mental health, 2) Assault and abuse 3) Experiences of treatment. The findings show the need for interprofessional collaboration between social and health care professionals such as social workers, community health workers, medical practitioners and psychologists to prevent and address issues of abuse and other social consequences experienced by COVID-19 survivors.

RESUMO

The paper examines the hygiene practices and health risk perception of vegetable sellers in urban Ghana. Based on a qualitative in-depth study of vegetable sellers drawn from five purposively sampled markets in Kumasi Metropolis, the study found that the vegetable sellers have generally low risk perception. Consequently, the vegetable handling practices by these market women remain largely unsafe presenting potential health risks to consumers. Regular monitoring by relevant agencies and sustained public education are therefore key for reducing market contamination which is critical for maintaining a healthy population.
