Risk of transmission of HIV to infants during breast/chest feeding when mothers/birthing parents living with HIV are on antiretroviral therapy: a protocol for a rapid review

Por: Djiadeu · P. · Begum · H. · Archibald · C. · Ekmekjian · T. · Busa · G. · Dansoh · J. · Van Nguyen · P. · Merckx · J. · Fleurant · A.
Introduction

HIV is a major public health issue affecting millions globally. Women and girls account for 46% of new HIV infections in 2022 and approximately 1.3 million females become pregnant every year. Vertical transmission of HIV from persons living with HIV (PLHIV) to infants may occur through different modalities, such as through breast/chest feeding. Notably, 82% of PLHIV who chose to breast/chest feed are on antiretroviral therapy (ART) when feeding their infants. Precise estimates of the risk of postpartum transmission to infants during breast/chest feeding at varying viral load levels remain a significant gap in the literature.

Methods and analysis

A rapid systematic search of electronic databases will be conducted from January 2005 to the present, including Medline, Embase and Global Health. The objective of this rapid review is to explore and assess the available evidence on the effect of varying viral load levels on the risk of HIV transmission to infants during breast/chest feeding when the birthing or gestational parent living with HIV is on ART. Study characteristics will be summarised and reported to support the narrative summary of the findings. The focus will be on the absolute risk of HIV transmission from birthing parent to infant during chest/breast feeding. The findings will also be stratified by month, including the risk of HIV transmission for 6 months and greater than 6 months postpartum. We will ascertain the risk of bias using A Measurement Tool to Assess Systematic Reviews 2, Quality of Prognosis Studies and Downs and Black checklist for the appropriate study type. A summary score will not be calculated, rather the strengths and limitations of the studies will be narratively described.

Ethics and dissemination

No human subjects will be involved in the research. The findings of this rapid review will inform a future systematic review and will be disseminated through peer-reviewed publications, presentations and conferences.

Objectives

The Modern Innovative Solutions to Improve Outcomes in Asthma, Breathlessness and Chronic Obstructive Pulmonary Disease (COPD) (MABC) service aimed to enhance disease management for chronic respiratory conditions through specialist multidisciplinary clinics, predominantly in the community. This study assesses the outcomes of these clinics.

Design

This study used a prospective, longitudinal, participatory action research approach.

Setting

The study was conducted in primary care practices across Hampshire, UK.

Participants

Adults aged 16 years and above with poorly controlled asthma or COPD, as well as those with undifferentiated breathlessness not under specialist care, were included.

Interventions

Participants received care through the multidisciplinary, specialist-led MABC clinics.

Primary and secondary outcome measures

Primary outcomes included disease activity, quality of life and healthcare utilisation. Secondary outcomes encompassed clinic attendance, diagnostic changes, patient activation, participant and healthcare professional experiences and cost-effectiveness.

Results

A total of 441 participants from 11 general practitioner practices were recruited. Ninety-six per cent of participants would recommend MABC clinics. MABC assessments led to diagnosis changes for 64 (17%) participants with asthma and COPD and treatment adjustments for 252 participants (57%). Exacerbations decreased significantly from 236 to 30 after attending the clinics (p

Conclusions

Specialist-supported multidisciplinary teams in MABC clinics improved diagnosis accuracy and adherence to guidelines. High patient satisfaction, disease control improvements and reduced exacerbations resulted in decreased unscheduled healthcare use and cost savings.

Prevalence and risk factors of metabolic syndrome in Ethiopia: describing an emerging outbreak in HIV clinics of the sub-Saharan Africa - a cross-sectional study

Por: Abdela · A. A. · Yifter · H. · Reja · A. · Shewaamare · A. · Ofotokun · I. · Degu · W. A.
Objectives

HIV-induced chronic inflammation, immune activation and combination antiretroviral therapy (cART) are linked with adverse metabolic changes known to cause cardiovascular adversities. This study evaluates the prevalence of lipodystrophy, and metabolic syndrome (MetS), and analyses risk factors in HIV-infected Ethiopians taking cART.

Methods

A multicentre cross-sectional study was conducted at tertiary-level hospitals. Eligible participants attending the HIV clinics were enrolled. Sociodemographic, anthropometric, clinical, HIV treatment variables, lipid profile, fasting blood glucose level, risk factors and components of MetS, also lipodystrophy, were studied. Data were analysed by SPSS statistical package V.25 with descriptive and analytical statistics. For multivariable analysis of risk factors, a logistic regression model was used. Results were presented in frequency and percentages, mean±SD, or median+IQR. Statistical significance was taken as p

Results

Among 518 studied participants, two-thirds were females, and the mean age of the study population was 45 years (SD=11). The mean duration of cART was 10 years (SD=4). Median CD4 count was 460 cells/mm3. The prevalence of MetS according to the Adult Treatment Panel III (2005) criteria was 37.6%. In multivariable analysis, independent risk factors for MetS were age >45 years (aHR 1.8, 95% CI 1.2 to 2.4), female sex (aHR 1.8, 95% CI 1.1 to 2.8), body mass index (BMI)>25 kg/m2 (aHR 2.7, 95% CI 1.8 to 4.1), efavirenz-based cART (aHR 2.8, 95% CI 1.6 to 4.8) and lopinavir/ritonavir-based cART (aHR 3.7, 95% CI 1.0 to 13.3). The prevalence of lipodystrophy was 23.6%. Prior exposure to a stavudine-containing regimen was independently associated with lipodystrophy (aHR 3.1, 95% CI 1.6 to 6.1).

Conclusion

Our study revealed 38% of the participants had MetS indicating considerable cardiovascular disease (CVD) risks. Independent risk factors for MetS were BMI≥25 kg/m2, efavirenz and lopinavir/ritonavir-based cART, female sex and age ≥45 years. In addition to prevention, CVD risk stratification and management will reduce morbidity and mortality in people with HIV infection.

Epidemiological transition: a historical analysis of immigration patterns by country of origin (1861-1986) related to circulatory system diseases and all-cause mortality in twentieth-century Australia

Por: Kelleher · C. C. · Kelly · G. E. · Segurado · R. · Briody · J. · Sellers · A. M. · McCalman · J.
Background and objectives

Circulatory system disease (CSD) patterns vary over time and between countries, related to lifestyle risk factors, associated in turn with socioeconomic circumstances. Current global CSD epidemics in developing economies are similar in scale to those observed previously in the USA and Australasia. Australia exhibits an important macroeconomic phenomenon as a rapidly transitioning economy with high immigration throughout the nineteenth and twentieth centuries. We wished to examine how that historical immigration related to CSD patterns subsequently.

Methods and setting

We provide a novel empirical analysis employing census-derived place of birth by age bracket and sex from 1891 to 1986, in order to map patterns of immigration against CSD mortality rates from 1907 onwards. Age-specific generalised additive models for both CSD mortality in the general population, and all-cause mortality for the foreign-born (FB) only, from 1910 to 1980 were also devised for both males and females.

Results

The percentage of FB fell from 32% in 1891 to 9.8% in 1947. Rates of CSD rose consistently, particularly from the 1940s onwards, peaked in the 1960s, then declined sharply in the 1980s and showed a strong period effect across age groups and genders. The main effects of age and census year and their interaction were highly statistically significant for CSD mortality for males (p

Conclusions

We argue our empirical calculations, supported by historical and socioepidemiological evidence, employing immigration patterns as a proxy for epidemiological transition, affirm the life course hypothesis that both early life circumstances and later life lifestyle drive CSD patterns.

Prevalence, correlates and common methods of non-suicidal self-injury in South Asia: a systematic review

Por: Haregu · T. · Chen · Q. · Arafat · S. M. Y. · Cherian · A. · Armstrong · G.
Introduction

The dynamics of self-harm vary substantially around the world, yet it is severely under-researched outside of a small number of high-income ‘Western’ countries. South Asia is disproportionately impacted by suicide, yet we know less about non-suicidal self-injury (NSSI) in the region.

Objective

To review and summarise evidence on the prevalence, correlates and common methods of NSSI in South Asia.

Methods

We searched Medline, Embase and PsycINFO for the period 1 January 2000 to 31 August 2023, for peer-reviewed observational studies. A total of 11 studies from eight South Asian countries that reported prevalence and/or correlates of NSSI were included in this review. We assessed the quality of the studies using the Study Quality Assessment Tools for Observational Cohort and Cross-Sectional Studies. We used meta-regression to describe the sources of heterogeneity. Abstracted data were summarised using thematic synthesis.

Results

For non-clinical populations, the 12-month prevalence of NSSI ranged from 3.2% to 44.8%, and the lifetime prevalence ranged from 21% to 33%. For clinical populations, the 12-month prevalence of NSSI ranged from 5% to 16.4%, while the lifetime prevalence ranged from 2% to 27%. Male sex, unemployment, financial stress, history of suicidal behaviour and depression were associated with a higher risk of NSSI. Better access to counselling services, higher self-esteem and self-knowledge were associated with a lower risk of NSSI.

Conclusion

The burden of NSSI in South Asia appears to be high in both clinical and non-clinical populations. Further research, especially with general population samples, is needed to build evidence on the epidemiology, context and meaning of NSSI in South Asia to inform the design of context-specific interventions.

Prognostic significance and clinical determinants of residual dyspnoea at discharge in acute heart failure: a single-centre, prospective observational study

Por: Garus · M. · Jura · M. · Guzik · M. · Zymlinski · R. · Iwanek · G. · Ponikowski · P. · Biegus · J.
Objective

This study aimed to assess the prognostic significance of residual (discharge) dyspnoea in acute heart failure (AHF) patients.

Design

Single-centre, prospective observational study.

Setting

Patients hospitalised for decompensated AHF in a single cardiology centre, in Poland.

Participants

All patients (n=202) who survived the hospitalisation with the primary diagnosis of AHF and were discharged from the hospital.

Primary and secondary outcome measures

1-year all-cause mortality; and the composite endpoint of 1-year all-cause mortality and rehospitalisation for the HF (whichever occurred first).

Results

On admission, 159 (78.7%) AHF patients presented dyspnoea at rest, while residual resting dyspnoea at discharge was present in 16 patients (7.9%). There were 48 (24%) patients with moderate/severe exertional dyspnoea at discharge. In the multivariable model, the resting dyspnoea at discharge was related to a higher risk of both 1-year mortality and composite outcome, with HR (95% CI) 8.0 (3.7 to 17.3) and 5.1 (2.6 to 10.2), respectively, both p

Conclusions

Among AHF patients the residual dyspnoea at discharge was unexpectedly common and was associated with an unfavourable outcome during 1-year follow-up.
