In Kenya, HIV-1 key populations including men having sex with men (MSM), people who inject drugs (PWID) and female sex workers (FSW) are thought to significantly contribute to HIV-1 transmission in the wider, mostly heterosexual (HET) HIV-1 transmission network. However, clear data on HIV-1 transmission dynamics within and between these groups are limited. We aimed to empirically quantify rates of
Active generative cooling based on supercritical hydrocarbon fuel is regarded as one of the most promising methods for scramjet thermal management. A large eddy simulation method is used to explore the transient change law of the initial flow, and heat transfer behaviors of supercritical hydrocarbon fuel is in rectangular channels. An oscillation effect can be proved in the convective heat transfe
Metal halide perovskites exhibit a rich crystal structure, with multiple phases as well as ferroelastic domains, which is crucial for the optical and electrical properties. The average crystal phase-transition temperatures can be shifted by size, strain, or defects, but it is not clear whether such differences can also appear locally within a single crystal. The experimental study of domain dynami
BACKGROUND: There has been a growing body of evidence associating consumption of ultra-processed foods (UPF) with adverse health outcomes including depression, cardiovascular disease, all-cause mortality. However, whether UPF are associated with dementia is unknown. The authors investigated the associations between UPF and dementia incidence in UK biobank.METHODS: We included 72,083 participants (
In recent decades, laser systems emitting pulses of light containing only a few electric field oscillations under their envelope have become common in many ultrafast optics laboratories. Owing to unique temporal characteristics and achieving extreme field strengths, these so-called few-cycle pulses have been instrumental in unlocking new regimes of light-matter interaction.The work presented in
The coronavirus 2019 (Covid-19) pandemic has affected both the private and public lives of people worldwide. Countries have chosen different strategies to reduce the spread of infection, including school closures and distance learning. This study aimed to describe school nurses’ perceptions about the wellbeing of students during the Covid-19 pandemic in Sweden. Interviews in five focus groups and
Infant massage is performed in various international contexts. There is a need for an updated literature review on this topic. The purpose of the current review was to investigate the effects of infant massage. A systematic literature review was conducted to investigate the effects of infant massage on the following outcomes: pain relief, jaundice, and weight gain. The inclusion criteria were infa
The purpose was to investigate stress among adolescents (16–19 years old) during the coronavirus disease 2019 (COVID-19) pandemic. Focus group (n = 9) interviews with students at upper secondary schools (16–19 years old, n = 41) were conducted in southern Sweden during the COVID-19 pandemic in 2021. The interviews were analyzed by qualitative content analysis. The analysis revealed five categories
Background: SARS-CoV-2, the causal agent of COVID-19, enters human cells using the ACE2 (angiotensin-converting enzyme 2) protein as a receptor. ACE2 is thus key to the infection and treatment of the coronavirus. ACE2 is highly expressed in the heart and respiratory and gastrointestinal tracts, playing important regulatory roles in the cardiovascular and other biological systems. However, the gene
Summary: This narrative review describes efforts to improve the care and prevention of fragility fractures in New Zealand from 2012 to 2022. This includes development of clinical standards and registries to benchmark provision of care, and public awareness campaigns to promote a life-course approach to bone health. Purpose: This review describes the development and implementation of a systematic a
Aim: To investigate school nurses’ experiences of health-promoting work to prevent stress in Swedish adolescents. Materials and methods: Swedish school nurses (n = 225) responded to a web survey with open-ended questions. The results were subjected to a qualitative content analysis. Results: Six categories were identified from the analysis: (1) Knowledge of body and soul, (2) Identifying stress an
Background and purpose — Information on outcomes after some modern total ankle replacement (TAR) designs is scarce. We therefore examined outcomes after trabecular metal (TM) TAR in Sweden by use of data from the national registry. Patients and methods — On December 31, 2020, 239 primary TM TARs had been reported to the Swedish Ankle Registry. We analyzed prosthesis survival probability, using exc
OBJECTIVES: We aimed to investigate whether sleep duration is associated with self-reported overall health, screen time, and nighttime texting among Swedish adolescents.METHODS: This was a cross-sectional survey of students (n = 1518) aged 13 to 15 years (50.7% girls) in southern Sweden.RESULTS: Fewer than 8 hours sleep duration before a school day was reported by 31% of students. The median time
BackgroundThe Minimal Insomnia Symptom Scale (MISS) is a three-item screening instrument that has been found to be psychometrically sound and capable of screening for insomnia among adults and older people. This study aimed to test the measurement properties of the MISS together with an additional item focusing on daytime functioning among adolescents using the Rasch measurement model.MethodsA cro
School nurses are one of the first health-care professionals to meet unaccompanied refugee children and adolescents and therefore have an important impact on health outcomes. The aim of this study was to describe school nurses' experiences working with unaccompanied refugee children and adolescents. Semistructured interviews were conducted with school nurses (n = 14) who worked with unaccompanied
This study aimed to investigate subjective health and its associations with perceived body image (body appearance and body functioning), physical activity, perceived wellbeing in school, perceived family financial situation, and body mass index among 13- to 15-year-old boys and girls. The study was a cross-sectional study performed in four municipalities in Southern Sweden. Data were obtained from
Osteoporotic fractures are one of the major problems facing healthcare systems worldwide. Undoubtedly, fragility fractures of the hip represent a far greater burden in terms of morbidity, mortality, and healthcare costs than other fracture sites. However, despite the significant impact on the health and quality of life of older adults, there is a general lack of awareness of osteoporosis, which re
This study focuses on communication and conceptions of obstetric care to address the postulates that immigrant women experience sensitive care through the use of an ethnically congruent interpreter and that such women prefer to meet health providers of the same ethnic and gender profile when in a multiethnic obstetrics care setting. During 2005-2006, we conducted in-depth interviews in Greater Lon
Background/Purpose: Rheumatoid arthritis (RA) is associated with an increased risk of cardiovascular disease (CVD). Systemic inflammation, driven by cytokines such as TNF, IL-6 and IL-17A, has been implicated as a contributing factor to CVD development in RA. The objective of this study was to investigate the impact of 92 inflammatory proteins on the risk of CVD events in patients with early RA.Me
