Article Synopsis
  • Children have shown strong immune responses to SARS-CoV-2 during various pandemic waves, with a significant increase in seropositivity from 34.2% after the first wave to 99.2% after the fifth wave, despite experiencing minimal severe illness.
  • The study found that IgG antibodies developed through natural exposure were effective in protecting children from future infections, with varying levels of effectiveness against different variants, showing the highest protection against the Beta variant and the least against Omicron.
  • Maternal seropositivity was linked to higher child seropositivity, indicating that the immune status of mothers plays a crucial role in the immune response of their children against COVID-19.

Background: Paediatric tuberculosis leads to more than 200 000 deaths annually. We aimed to investigate the incidence of Mycobacterium tuberculosis infection and tuberculosis disease in the first decade of life in the Drakenstein Child Health Study (DCHS), a South African cohort in a community with high tuberculosis and HIV incidence.

Methods: In this prospective birth cohort study, we enrolled pregnant women aged 18 years or older who were between 20 and 28 weeks' of gestation in a peri-urban setting outside of Cape Town, South Africa.

Article Synopsis
  • Poor fit between work expectations and the work environment leads to high levels of stress among early career occupational therapists, particularly those with less than 5 years of experience.
  • A study involving 261 South African occupational therapists used the Area of Work-Life Survey (AWS) to analyze factors influencing work-life areas like workload, control, and community.
  • Results indicated that while most work-life areas scored normal or high, workload was notably low, especially for those in public health settings and physical rehabilitation, suggesting a need for improved support in these environments.

Article Synopsis
  • International guidelines suggest stopping cervical screenings at age 50 if two consecutive tests are negative, but many women over 50 in LMICs, like Botswana, haven't had the chance to screen.
  • The study analyzed data from two separate cohorts—one for screening with 2,570 women aged 30+ and another with 1,520 cervical cancer patients—to understand the prevalence of cervical dysplasia and cancer stages by age and HIV status.
  • Results showed similar prevalence rates of cervical intraepithelial neoplasia (CIN) between women aged 30-49 and 50+, regardless of HIV status, indicating no significant differences in disease prevalence across these age groups.

Purpose: Peer support has been identified as an important aspect of rehabilitation for visually impaired adults. However, there is a limited exploration in rehabilitation studies literature of the identity-related impact of these interventions, both at an individual and collective level. Through attending to the discourses on blindness, well-being, and social inclusion that circulate in organization cultures, this article considers the role that peer support plays in forming "blind communities" with particular characteristics, and what these communities might model about life with blindness, both to newly blind persons and to society.

Research has suggested that autistic people enjoy spending time with other autistic people and find them easier to talk to. We wanted to find out what autistic people say about spending time with other autistic people and whether this makes their life better. We found 52 papers which described this and reviewed what they found.

Background: Two-thirds of people living with human immunodeficiency virus type 1 (HIV-1) infection reside in Sub-Saharan Africa, where there are the highest prevalence and incidence rates of human papillomavirus (HPV) infection. Both infections are sexually transmitted and enter the body via the epithelium. This review describes the extent of involvement of the epithelium in each infection in the female genital tract.

Background: Cervical cancer screening strategies should ideally be informed by population-specific data. Strategies recommended for secondary prevention, are often inadequately studied in populations with high cervical disease burdens. This report describes the test performance measured against CIN2 + /CIN3 + histology in HIV-positive women (HPW) and HIV-negative women (HNW) with the aim to determine the most effective strategies to identify South African women at risk.

People with visual impairment face significant material challenges to access and inclusion in South Africa. These are in large part rooted in and supported by prejudiced assumptions about the needs, nature and capabilities of this group. The cultural and psychological face of oppression needs to be attended to.

Background: Cervical cancer poses a significant burden, particularly in low-and-middle income countries (LMIC) with limited access to healthcare. High-income countries have made progress in prevention, while LMIC face unacceptably high incidence and mortality rates, often lacking official screening recommendations. We analysed the presence and content of cervical cancer screening guidelines for the secondary prevention of cervical cancer in the Southern African Development Community (SADC) and compared it to the current World Health Organization (WHO) guidelines for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention.

Although research has the potential to improve autistic people's lives, lots of funding goes towards research looking at topics which autistic people say has little impact in their everyday lives. Autistic people's lives can be different depending on where they live, and Scotland is a unique country in many ways. We wanted to find out which topics autistic people in Scotland want to see research on.

Lots of people seek an autism diagnosis as an adult, and they often say that being diagnosed can be positively life-changing, but the experience of getting a diagnosis can be difficult. We often do not hear the views of people currently looking for a diagnosis, or talk to them about how diagnosis relates to their identity. In our study, we looked at experiences of people currently seeking an autism diagnosis in the UK.

The "double empathy problem" refers to breakdowns in communication and understanding that frequently occur between autistic and non-autistic people. Previous studies have shown that autistic people often establish better rapport and connection when interacting with other autistic people compared to when interacting with non-autistic people, but it is unclear whether this is noticeable to non-autistic observers. In this study, 102 non-autistic undergraduate students viewed and rated video recordings of "get to know you" conversations between pairs of autistic and non-autistic adults.
