Background
Pregnancy triggers physiological adjustments through hormonal changes, supporting foetal growth and preparation for labour. Becoming more pronounced with excessive weight, these changes may trigger pathophysiological changes and unmask pre-existing disease conditions. In developing countries, many pregnant women experience either inadequ...
Introduction
The prevalence of type 2 diabetes is on a rapid rise in Tanzania, driven by lifestyle modifications, nutritional changes, and increased obesity rates. This article reviews the epidemiology, and disease trends of type 2 diabetes in Tanzania and explores the economic implications and challenges in care, including policy, education, and h...
Introduction
Despite the prevalence of respiratory disorders in the gravid state, and the crucial role of spirometry in respiratory medicine, its utility for assessing lung function during pregnancy remains infrequent. Putative reasons for this include reservations regarding spirometry performance and its potential influence on test outcomes, altho...
Introduction
Manufacturing factory workers in developing countries are at an increased risk of developing hearing loss from continuous exposure to high noise levels without hearing protection. However, use of hearing protection such as earmuffs has been an intervention of choice in many workplaces due to impracticability of engineering and administ...
Introduction
The use of hearing protection devices (HPDs) has been an intervention of choice in many workplaces such as in the construction industry for quite some time due to impractical effects of engineering and administrative interventions. Questionnaires for assessment for HPDs use among construction workers have been developed and validated i...
Background:
Spirometry is a commonly used lung function test. It assesses respiratory functions by measuring the air volume and the rate at which a person can exhale from lungs filled to their total capacity. The most helpful spirometry parameters are: forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory...
Temporal lobe epilepsy (TLE) is difficult to treat as it is often refractory to treatment. Apart from traditional medical treatment, surgical resection is also a choice of treatment, but it may be associated with significant cognitive deficits. As a result, treatment strategies using targeted and adjustable stimulation of malfunctioning brain circ...
Background: Lung function tests are done to assess the working and possible mechanical deterioration of lungs, respiratory muscles, and chest wall. Spirometry is a commonly used test. Pregnancy derives an altered physiological state due to accompanied hormonal and anatomical changes that affect the respiratory system. Despite that, spirometry is ra...
Background:
Workers in iron and steel factories in Tanzania are exposed to noise levels above recommended limit values, without using hearing protection devices. Exposure to noise levels above 85 dB(A) is associated with temporary threshold shifts (TTS) of human hearing. Nevertheless, there are few studies of noise and hearing from African countri...
Workers represent half of the world’s population and are the major contributors to socio-economic development. Continued, sustainable socio-economic development is only possible if workers have a decent working environment. The headline for Sustainable Development Goal 8 is to ‘Promote sustained, inclusive and sustainable economic growth, full and...
We assessed Knowledge Attitude and Practice (KAP) regarding occupational noise exposure, Noise-induced hearing loss, audiometry and use of hearing protection devices among iron and steel factory workers exposed to high noise level. A modified, validated, structured questionnaire was used to collect information from 253 male workers randomly selecte...
Iron and steel factory workers in Tanzania are likely to develop noise-induced hearing loss (NIHL) due to exposure to high sound levels. Studies on hearing status in this population are lacking. The aims of this study were to determine prevalence of NIHL among iron and steel workers and compare hearing thresholds at different frequencies with a con...
Background:
Machines, processes, and tasks in the iron and steel factories may produce noise levels that are harmful to hearing if not properly controlled. Studies documenting noise exposure levels and related determinants in sub-Saharan Africa, including Tanzania are lacking. The aim of this study was to document noise exposure and to identify de...
Introduction
Noise induced hearing loss (NIHL) is apreventable disease. However, the global burden of NIHL is increasing; especially in developing countries. The prevalence of NIHL among metal industry workers in Sub Saharan countries including Tanzania is not well documented.
Methods
This study was conducted among male metal industry workers (Exp...
Introduction
Machines and processes in the metal industry produce noise levels that are harmful to the human ear if not properly controlled. Empirical studies are lacking to document noise exposure which is one of the stepping stones towards development and enforcement of policies, and standards on noise control in developing countries, including T...
Objective: Assessment of changes in fractional exhaled nitric oxide (FENO) across the shift was performed among cement production workers and controls. FENO was used as a possible marker of eosinophilic inflammation in the airways. In addition, the relations between personal total dust exposure and FENO changes across the work shift were examined....
Background:
Several studies have reported associations between cement dust exposure and adverse respiratory health effects, but there are few follow-up studies and no studies of respiratory health effects following dust control measures.
Aims:
To assess changes in respiratory health among cement workers and unexposed controls after 1 year in a f...
To compare total dust exposure, prevalence of chronic respiratory symptoms, lung function, and chronic obstructive pulmonary disease (COPD) among Tanzanian cement workers before (2002) and after (2010-2011) establishment of dust-control measures.
Personal total dust-exposure measurements, questionnaire assessment for chronic respiratory symptoms, a...
Background
It has been suggested that dust exposure causes airway inflammation among cement factory workers. However, there is limited information on the mechanisms of this effect. We explored any associations between total dust exposure and fractional exhaled nitric oxide (FENO) as a marker of airway eosinophilic inflammation among cement producti...
