RESUMO
Renal dysfunction is a common comorbidity in patients with advanced heart failure who may benefit from mechanical circulatory support (MCS). Unfortunately, renal function may result after left ventricular assist device (LVAD) implantation. The purpose of this study is to examine the outcomes of advanced heart failure patients with end-stage renal disease (ESRD) requiring mechanical circulatory support as a bridge to transplant (BTT) or destination therapy (DT). We searched Medline, Embase, and Cochrane in September 2021. The following keywords were used: left ventricular assist device or LVAD and end-stage renal disease or ESRD. Our study included case reports, case series, descriptive studies, and randomized control trials. Review articles, guidelines, systematic reviews, and meta-analyses were excluded. We also excluded pediatric cases. We identified 278 articles; 92 were duplicated, 186 articles entered the screening phase, and 133 articles were excluded by title and abstract. After the full-text screening, 40 articles were excluded. This systematic review included 13 articles. Among the contraindications to LVAD implantation, a general contraindication is for patients found to have stage 4 chronic kidney disease (CKD) (estimated glomerular filtration rate (eGFR): <30 mL/minute/1.73 m2), while those on dialysis are an absolute contraindication LVAD implantation. Despite the limited data and publications on LVADs in patients with ESRD, LVAD implantation as a bridge to transplantation or destination therapy may be considered in selected patients without increasing morbidity and mortality. Therefore, shared decision-making around the treatment of advanced heart failure with these patients and the care team is essential.
RESUMO
OBJECTIVE: To analyze the factors behind the underutilization of research articles as an adjuvant source of knowledge by medical students. MATERIALS & METHODS: We conducted a cross-sectional study of students from medical colleges in Islamabad from June 2017 to August 2017. The students were verbally informed about the study, and those who gave their consent were included. The data was collected through a self-constructed questionnaire. Cronbach's alpha was used to assess the internal consistency of the questionnaire, and it was found to be 0.68. The data obtained was analyzed on IBM's statistical package for the social sciences (SPSS) version 21 (IBM, Armonk, NY, US). RESULTS: A total of 382 students participated in the study. The use of research articles for the preparation of problem-based learning (PBL), small group discussions, or assessments was very low. Students did, however, consult journals if emphasized by the faculty. A majority of the students did appreciate the importance of medical journals to explore detailed information about disease states and health issues encountered by self or family members. The use of research articles by students for preparing for exams was very low. CONCLUSION: The students' underutilization of journals may be attributable to an over-familiarity with books, a lack of faculty prompting, and a lack of knowledge on how to access such journals. These factors should be addressed while designing the medical curriculum to enhance journal perusal among medical students.
