Factors Associated With Non-Uptake Of Implantable Cardioverter-Defibrillator (Icd) Among Eligible Patients At A Tertiary Hospital In Kenya, Emmanuel Benge Aluoch

Theses & Dissertations

Background: Sudden Cardiac Death (SCD) is a major cause of mortality among patients with cardiovascular disease accounting for about 50% of deaths. Several studies have demonstrated the safety and efficacy of Implantable Cardioverter-Defibrillator (ICD) implantation in both primary and secondary prevention of SCD in at-risk populations. Despite well-publicized guidelines, ICD implantation rates remain low particularly in Africa with a paucity of data regarding factors associated with non-uptake and reasons for implant refusal. The study aimed to characterize these factors and identify reasons for ICD refusal. Understanding these factors and reasons for non-implantation will provide an opportunity to optimize ICD uptake …

Diagnostic Utility Of Red Cell Indices In Relation To Serum Iron Indices For Evaluation Of Iron Deficiency In Heart Failure, Larry Wangai Mburu

Theses & Dissertations

Background: Iron deficiency (ID) in heart failure (HF) causes poorer outcomes, and evaluation using ferritin and transferrin saturation (TSAT) in our setting is hampered by cost and availability. Though the red cell indices (RCIs), routinely used for assessment of ID anaemia, have shown utility in predicting outcomes in HF, they have not been evaluated in this population for prediction of ID relative to the iron indices. A combination of the RCIs, the combined cell index (CCI), may be more accurate. Validating the diagnostic accuracy of the RCIs would improve evaluation of ID in low-resource settings and improve uptake of iron …

Utility Of Glasgow-Blatchford Scoring System In Identification Of Low Risk Patients With Upper Gastrointestinal Bleeding In Emergency Departments In Dar Es Salaam Hospitals, Tanzania, Selestin D. Mpiri

Theses & Dissertations

Background: Acute upper gastrointestinal bleeding (UGIB) remains a common cause of visits to the Emergency Department (ED). To stratify the risk of complications, rebleeding, need for clinical intervention, or death, several clinical scores are in use. Glasgow-Blatchford Score (GBS) is an excellent risk assessment tool and has shown to accurately identify patients with a low risk of death or requiring intervention. In urban Tanzania, there is a lack of standardized protocol and a well-validated risk assessment tool for analyzing patients presenting with UGIB symptoms. Good performance of GBS score and its use will help to reduce unnecessary emergency endoscopies …

Prevalence And Outcome Of Asymptomatic Cryptococcal Antigenemia In Art Naive And Art Experienced Hiv Patients In Dar Es Salaam, Tanzania, Charles Mandela Makakala

Theses & Dissertations

Introduction: Cryptococcal meningitis (CM) is a highly fatal disease and contributes to about 20% of all-cause mortality in HIV/AIDS. Sub-Saharan Africa is facing substantial challenges in the treatment of the disease; the focus has been shifted towards prevention of the condition in ART-naive patients with CD4 counts of less than 100 cells/μL. Most studies and interventions have been conducted on ART-naive HIV patients despite there being cases and deaths due to cryptococcal meningitis among ART-experienced patients. Recent studies have shown that although there is an increase in ART coverage among HIV patients, this has not affected the incidence of cryptococcal …

Comparison Of The Sofa And Qsofa Scores In Predicting In-Hospital Mortality Among Adult Critical Care Patients With Suspected Infection., Mohammed Said

Eligibility And Patient Barriers To Peritoneal Dialysis In Patients With Advanced Chronic Kidney Disease, Saleem Mohamed Abdulkarim

Theses & Dissertations

Introduction: The burden of chronic kidney disease is on the rise in Kenya and is a significant cause of morbidity and mortality. While definitive treatment is renal transplantation, many patients require renal replacement therapy in the form of hemodialysis or peritoneal dialysis. The predominant modality utilized in Kenya is currently hemodialysis despite peritoneal dialysis having similar survival outcomes with the potential benefit of cost-effectiveness. There is need therefore to explore why peritoneal dialysis remains underutilized and whether patient factors may be contributory to barriers that limit the uptake of peritoneal dialysis.

Purpose: The main objective of this study is to …

Factors Associated With Cardiac Dysfunction Following Anthracyline-Based Chemotherapy In Adults In A Tertiary Hospital In Nairobi, Joseph Odunga Abuodha

Early detection of cardiotoxicity provides an opportunity for treatment adjustment. Several parameters predict development of clinically manifest cardiac dysfunction. The study aimed to evaluate clinical and echocardiographic parameters which predict development of cardiac dysfunction in a sub-Saharan African population.

Methods: Patients with a diagnosis of cancer and receiving anthracyclines at AKUH,N were evaluated if they met eligibility criteria (≥18years at first anthracycline administration, archived baseline echocardiogram, no prior history of heart disease or use of anthracyclines). …

Barriers To Definitive Hyper-Acute Management Of Stroke At A Tertiary Facility In Nairobi, Kenya, Caroline Wangui Mithi

Theses & Dissertations

Background: Stroke is a sudden neurological deficit due to a vascular cause, which can be ischaemic, haemorrhagic stroke or another cause. It is a leading cause of disability and long term functional impairment in the world. The definitive management of an acute ischaemic stroke is thrombolysis and/or mechanical thrombectomy, both of which has been shown to improve functional outcome but the utilization remains quite low in most hospitals, especially in Africa. This is due to certain pre-hospital and in-hospital barriers, and these factors have been shown to differ from country to country.

Objective: To determine the pre-hospital barriers that prevent …
