Geographic distribution of COPD prevalence in the world displayed by Geographic Information System maps

Blanco, I.; Diego, I.; Bueno, P. et al. (2019) CC2

Existing data on chronic obstructive pulmonary disease (COPD) prevalence are irregularly distributed around the world, and in many geographic regions data are scarce or even nonexistent. This fact hinders the implementation of adequate preventive and therapeutic interventions to reduce the high burd... more

Task-shifting to improve asthma education for Malawian children: a qualitative analysis

Nkhalamba, L.; Rylance, S.; Muula, S. A. et al. Human Resources for Health (2021) CC

Background Asthma education, a key component of long-term asthma management, is challenging in resource-limited settings with shortages of clinical staff. Task-shifting educational roles to lay (non-clinical) staff is a potential solution. We conducted a randomised controlled trial of an enhanced a... more

Symptom-based screening tool for asthma syndrome among young children in Uganda

Nantanda, R.; Siersma, V.; Ndeezi, G. et al. npj Primary Care Respiratory Medicine (2020) CC

Under-diagnosis of asthma in ‘under-fives’ may be alleviated by improved inquiry into disease history. We assessed a questionnaire-based screening tool for asthma among 614 ‘under-fives’ with severe respiratory illness in Uganda. The questionnaire responses were compared to post hoc consensu... more

Parental understanding of wheeze and its impact on asthma prevalence estimates

Michel, G.; Silverman, M.; Strippoli, M-P. F. et al. European Respiratory Journal (2006) CC

The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”. In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definition of wheeze was assessed. Predictors of a correct ... more

Asthma Control Test: Reliability, validity, and responsiveness in patients not previously followed by asthma specialists

Schatz, M.; Sorkness, C. A.; Li, J.T; et al. (2006) CC2

The development of the Asthma Control Test (ACT), a short, simple, patient-based tool for identifying patients with poorly controlled asthma, was recently described in patients under the routine care of an asthma specialist. We sought to evaluate the reliability and validity of the ACT in a longi... more

Prevalence, Etiology, and Outcome of Sepsis among Critically Ill Patients in Malawi

Prin, M.; Onofrey, L.; Purcell, L; et al. (2020) CC2

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to ... more

Worldwide rates of diagnosis and effective treatment for cystic fibrosis

Guo, J.; Garratt, A.; Hill, A. Journal of Cystic Fibrosis (2022) CC

Time has seen management for Cystic Fibrosis (CF) advance drastically, most recently in the development of the disease-modifying triple combination therapy ivacaftor/tezacaftor/elexacaftor. There is currently limited evidence regarding both the global epidemiology of CF and access to this transforma... more

The failure of community-based health insurance schemes in Tanzania: opening the black box of the implementation process

Kigume, R.; Maluka, S. (2021) CC2

Globally, there is increased advocacy for community-based health insurance (CBHI) schemes. Like other low and middle-income countries (LMICs), Tanzania officially established the Community Health Fund (CHF) in 2001 for rural areas; and Tiba Kwa Kadi (TIKA) for urban population since 2009. This ... investigated the implementation of TIKA scheme in urban districts of Tanzania. more

Infrastructure, policy and regulatory interventions to increase physical activity to prevent cardiovascular diseases and diabetes: a systematic review

Durão, S.; Burns, J.; Schmidt, B. et al. BMC Public Health (2023) CC

Background Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity. Methods We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction. Results We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence). Conclusions Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings. more
