Systematic Reviews in Surgical Decision Making: Unpacking the Data

The practice of surgery has always involved a process of trying to understand the pathophysiology of surgical conditions and introducing interventions to alter their course. With time, numerous interventions have become available and contemporary surgical practice warrants that surgeons possess skills in utilizing the best available high quality evidence for patient care. Such evidence is afforded by systematic reviews. Utilizing such reviews involves a process of reading and interpretation in which the surgeon attempts to determine whether a sensible clinical question was addressed, the search for relevant literature was exhaustive, assessment of identified studies was reproducible, reported results were properly summarized and whether any recognized benefits are worth the potential risks and costs of the intervention. This process aids the surgeon when making recommendations regarding treatment and it must incorporate patient values and preferences.Key words: Systematic Reviews, Evidence Based Surger

Cardiac obstetric care in Botswana

Cardiovascular diseases (CVD) in pregnancy are significant causes of maternal mortality in Botswana. Like other developing countries, acquired CVD such as hypertensive disorders, rheumatic heart disease and cardiomyopathy are common in Botswana. CVD-related maternal deaths are often attributed to failure to provide risk-appropriate care. A multidisciplinary pregnancy heart team is an essential approach in managing CVD in pregnancy and improving maternal and foetal outcomes. Given that more women with CVD are becoming pregnant in Botswana, we review the current practice, gaps, and potential areas of improvement

Genetic Diversity Among Tilapia Species Farmed at Chita in Kilombero, Morogoro Region, Tanzania

The development of aquaculture industry in Tanzania cannot cope with the expected substantial increase in demand for fish and fish products due to several bottlenecks including unavailability of good quality feeds and fingerlings. Fish farmers often complain about slow growth rate of the farmed fish necessitating genetic characterization. This study identified and determined the genetic diversity of tilapia species farmed in Kilombero Districts at Chita earthen ponds. Fish samples were collected from nine earthen ponds belonging to small-scale fish farmers for genetic characterization. Total DNA was extracted by using the phenol-chloroform technique. The genetic diversity was calculated by using the Arlequine version 3.01. The study found that, 90% of the sampled fish at Chita were Oreochromis niloticus, while 5.5% were Bathybates minor. There was low genetic diversity in the farmed tilapia, suggesting the possibility of inbreeding effects and a limited number of founder broodstock in the populations. Therefore, successful aquaculture development in Tanzania requires well-managed and effective fish breeding programs for production of good quality fingerlings through fish genetic resources management.

Poverty and Cardiovascular Diseases in Sub-Saharan Africa

There is a rise in cardiovascular diseases (CVDs) in sub-Saharan Africa (SSA). Even though SSA is home to 14% world’s inhabitants, it is home to more than half of the global poor. The objective of this chapter is to evaluate the interconnection between CVD and poverty in SSA. We found that the relationship between poverty and CVD is bidirectional. The intersection between poverty and CVD cuts through primordial, primary prevention and secondary prevention interventions. In the context of poverty in SSA, CVD prevention is a challenge due to competing demands to address the never conquered infectious diseases exacerbated by the current COVID-19 pandemic. With a weak healthcare system and out of pocket payment for the costs of CVD care, a significant proportion of individuals with CVD and their households are consequently impoverished. Besides, CVD affects a younger and productive population in SSA than in the rest of the world. Thus, CVD-related loss of productivity progressively pushes an additional number of individuals into poverty, requiring urgent attention

Pericardial cyst with right ventricular compression

Pericardial cysts are infrequent and benign mediastinal lesions. While most pericardial cysts are asymptomatic, some patients may present with compression symptoms. We present the case of a 22-year-old man who presented with a right pericardial cyst that caused compression of the right ventricle. Pan African Medical Journal 2012; 12:6

Spatial patterns of zooplankton distribution and abundance in relation to phytoplankton, fish catch and some water quality parameters at Shirati bay, lake victoria-Tanzania

Spatial patterns and abundance of zooplankton in aquatic habitats are important determinants for production of fish species, invertebrates and availability of phytoplankton. Weekly monitoring for zooplankton abundance was conducted in Shirati Bay, Lake Victoria, to explore their spatial patterns in relation to phytoplankton, fish catch and some water quality parameters. The vertical distribution of zooplankton was generally higher close to the bottom as compared to surface waters of the lake. Zooplankton vertical distribution positively correlated with water transparency (r = 0.680, p = 0.011). The horizontal abundance of zooplankton was not significantly different amongst the three stations (p = 0.5143). While Copepoda was the dominant group in terms of composition, Rotifera had the highest diversity indices of all the zooplankton groups obtained. The abundance of nauplius larvae was significantly higher than that of the copepodites (p = 0.022). Nile perch, Lates niloticus dominated the total catches (47%) followed by Nile tilapia, Oreochromis niloticus (29%) and haplochromines (21%). The abundance of haplochromines and juvenile fishes correlated significantly with the abundance of zooplankton (r = 0.856, p = 0.002 and r = 0.58, p = 0.038, respectively). The current study revealed that zooplankton vertical distribution at Shirati Bay is mainly controlled by water transparency and predation by juvenile Nile perch, Nile tilapia and haplochromines.Keywords: chlorophyll-a; calanoid; cyclopoid; nauplius larvae; juvenile fis
