Becoming and Being a Woman: Meanings and Values of Labial Elongation for Zambians in Cape Town

Zambian women might doubt whether to stop or preserve labial elongation, which is a female genital modification instructed to the girl child as the first rite of passage into womanhood. We conducted a grounded theory research among Zambian men and women who had immigrated to Cape Town. Twenty women and seventeen men participated. Beliefs and perceptions around womanhood, gender roles and pleasure place elongation as a practice that is highly valued by Zambians in South Africa. Interventions to promote and improve women’s sexual health -such as capacity building of healthcare professionals and design of information, education and communication materials- can be informed by framing and documenting the implications for the Zambian migrant women’s sexual and social wellbeing of this practice

Tuberculous Pericarditis is Multibacillary and Bacterial Burden Drives High Mortality

AbstractBackgroundTuberculous pericarditis is considered to be a paucibacillary process; the large pericardial fluid accumulation is attributed to an inflammatory response to tuberculoproteins. Mortality rates are high. We investigated the role of clinical and microbial factors predictive of tuberculous pericarditis mortality using the artificial intelligence algorithm termed classification and regression tree (CART) analysis.MethodsPatients were prospectively enrolled and followed in the Investigation of the Management of Pericarditis (IMPI) registry. Clinical and laboratory data of 70 patients with confirmed tuberculous pericarditis, including time-to-positive (TTP) cultures from pericardial fluid, were extracted and analyzed for mortality outcomes using CART. TTP was translated to log10 colony forming units (CFUs) per mL, and compared to that obtained from sputum in some of our patients.FindingsSeventy patients with proven tuberculous pericarditis were enrolled. The median patient age was 35 (range: 20–71) years. The median, follow up was for 11.97 (range: 0·03–74.73) months. The median TTP for pericardial fluid cultures was 22 (range: 4–58) days or 3.91(range: 0·5–8·96) log10CFU/mL, which overlapped with the range of 3.24–7.42 log10CFU/mL encountered in sputum, a multi-bacillary disease. The overall mortality rate was 1.43 per 100 person-months. CART identified follow-up duration of 5·23months on directly observed therapy, a CD4+ count of ≤199.5/mL, and TTP≤14days (bacillary load≥5.53 log10 CFU/mL) as predictive of mortality. TTP interacted with follow-up duration in a non-linear fashion.InterpretationPatients with culture confirmed tuberculous pericarditis have a high bacillary burden, and this bacterial burden drives mortality. Thus proven tuberculosis pericarditis is not a paucibacillary disease. Moreover, the severe immunosuppression suggests limited inflammation. There is a need for the design of a highly bactericidal regimen for this condition

Paediatric asthma and non-allergic comorbidities : a review of current risk and proposed mechanisms

It is increasingly recognized that children with asthma are at a higher risk of other non-allergic concurrent diseases than the non-asthma population. A plethora of recent research has reported on these comorbidities and progress has been made in understanding the mechanisms for comorbidity. The goal of this review was to assess the most recent evidence (2016-2021) on the extent of common comorbidities (obesity, depression and anxiety, neurodevelopmental disorders, sleep disorders and autoimmune diseases) and the latest mechanistic research, highlighting knowledge gaps requiring further investigation. We found that the majority of recent studies from around the world demonstrate that children with asthma are at an increased risk of having at least one of the studied comorbidities. A range of potential mechanisms were identified including common early life risk factors, common genetic factors, causal relationships, asthma medication and embryologic origins. Studies varied in their selection of population, asthma definition and outcome definitions. Next, steps in future studies should include using objective measures of asthma, such as lung function and immunological data, as well as investigating asthma phenotypes and endotypes. Larger complex genetic analyses are needed, including genome-wide association studies, gene expression-functional as well as pathway analyses or Mendelian randomization techniques; and identification of gene-environment interactions, such as epi-genetic studies or twin analyses, including omics and early life exposure data. Importantly, research should have relevance to clinical and public health translation including clinical practice, asthma management guidelines and intervention studies aimed at reducing comorbidities.Swedish Research Council (grant no 2018-02640)Swedish Heart-Lung Foundation (grant no 20210416)Publishe

Perceptions of youth-friendly sexual and reproductive health services in selected Higher and Tertiary Education Institutions of Zambia: A qualitative study on the perspectives of young people and healthcare providers

The recognition of the need for Adolescent and Youth-Friendly Health Services (AYFHS) is growing. It is important to ensure the provision of high-quality sexual and reproductive health (SRH) services that cater to the unique needs of adolescents and young people (AYP). Adolescents and young people spend a significant amount of time in Higher and Tertiary Education Institutions (HTEIs) where adolescent friendly services are needed. However, there is limited evidence on the availability of sexual and reproductive health services for young people in HTEIs in Zambia. Using the Human Rights Based Approach to healthcare availability, accessibility, acceptability, and quality of care (AAAQ) framework, this study explores young people’s perceptions of youth-friendly sexual and reproductive health services in selected HTEIs in Zambia. Between March and June 2021, a qualitative case study was conducted in 12 selected HTEIs located in Lusaka, Central, and Copperbelt provinces of Zambia. The study employed In-depth Interviews (IDIs) and Focus Group Discussions (FGDs) with AYPs, as well as Key-informant Interviews (KIIs) with healthcare providers. The healthcare providers at health facility, district and provincial levels were interviewed to provide insights about the services provided in the HTEIs. A total of 112 interviews were conducted. Data analysis was performed using thematic analysis in NVivo version 11. In the study, young people reported the availability of primary health services like malaria, HIV, and pregnancy testing, as well as screening for STIs. However, their awareness of SRH services was limited. Contraception, STI testing and treatment, and HIV and pregnancy screening and testing were the most accessed services. Equipment and commodity shortages were common, hindering care provision. Young people found healthcare services in educational institutions inaccessible, with limited comprehensive care and understanding from providers. Services lacked tailoring for key populations and privacy/confidentiality. Health care providers also reported inadequate youth-friendly spaces, equipment, medication and trained workers which compromised the quality of care. Peer educators and provider training were seen as essential for improving accessibility and acceptability of services. The findings indicate significant barriers to the accessibility, availability, and acceptability of SRH services for AYP in HTEIs in Zambia. There is a pressing need to enhance AYSRH programming by increasing awareness of services and ensuring their availability and accessibility for young people. Sufficient funding for AYFHS can address challenges related to service quality, including inconsistent availability of medical equipment and supplies. Building the capacity of service providers can potentially enhance the uptake of services by AYP. It is crucial to target services to address the specific vulnerabilities of students with disabilities and key populations, aligning with the goal of achieving universal health coverage and leaving no one behind

Dog Ownership and Cardiovascular Disease

The relationship between pet ownership and human health has been studied extensively; however, the effect of dog ownership on human health has had conflicting results. The overall aim of this research project was to investigate the impact of dog ownership, and the death of the dog, on human cardiovascular health and all-cause mortality. Study I was a population-based study investigating the association between dog ownership with the risk of cardiovascular disease (CVD) and death. Of 3,432,153 individuals included, dog ownership (13.1%) was associated with a lower risk of CVD- and all-cause death by 23% and 20%, respectively. In single-person households, there was an inverse association between dog ownership and incident CVD, as well as a stronger inverse association with CVD-death and all-cause death. Study II was a population-based study investigating the association between dog ownership and initiation of treatment for cardiovascular risk factors in 2,026,865 adults. Dog ownership (14.6%) was associated with a slightly elevated risk of initiating treatment (2%) for hypertension and dyslipidaemia, but not for diabetes mellitus. However, some evidence for residual confounding was found. Study III investigated the risk of death after hospitalization for a first-ever acute myocardial infarction (n=181,696) or first-ever ischemic stroke (n=157,617) in two population-based cohorts. Dog ownership was associated with a 20% to 24% lower risk of all-cause mortality and CVD-death, respectively. In Study I-III, ownership of hunting breed dogs was associated with the lowest risk of the outcomes, while owning dogs of mixed pedigree was associated with worse cardiovascular health. Study IV found evidence of an increased risk of CVD after the loss of a life-insured pet (dog or cat; n=147,251) during the first week, 3-6 months after and 6-12 months after pet-loss. This thesis has used the Swedish population and health registers to investigate the relationship between various aspects of dog ownership and cardiovascular risk. By using defined, quantifiable end-points and robust statistical methods, this project has made an important contribution to the body of research underlying the positive relationship between dog ownership and cardiovascular health, paving the way for further research into causal mechanisms

Climate variability and infectious diseases nexus: Evidence from Sweden

Many studies on the link between climate variability and infectious diseases are based on biophysical experiments, do not account for socio-economic factors and with little focus on developed countries. This study examines the effect of climate variability and socio-economic variables on infectious diseases using data from all 21 Swedish counties. Employing static and dynamic modelling frameworks, we observe that temperature has a linear negative effect on the number of patients. The relationship between winter temperature and the number of patients is non-linear and âUâ shaped in the static model. Conversely, a positive effect of precipitation on the number of patients is found, with modest heterogeneity in the effect of climate variables on the number of patients across disease classifications observed. The effect of education and number of health personnel explain the number of patients in a similar direction (negative), while population density and immigration drive up reported cases. Income explains this phenomenon non-linearly. In the dynamic setting, we found significant persistence in the number of infectious and parasitic-diseased patients, with temperature and income observed as the only significant drivers.
