Global, regional and national burden of infections among pregnant women, 1990-2021: a prospective cohort study

Objectives
We aimed to analyse the trends, age distribution and disease burden of maternal sepsis and other maternal infections (MSMI) to improve management strategies.

Design
We extracted data from the global burden of disease (GBD) 2021 database to evaluate MSMI burden with different measures for the whole world, 21 GBD regions and 204 countries from 1990 to 2021.

Setting
Studies from the GBD 2021 database generated by population-representative data sources identified through a literature review and research collaborations were included.

Participants
Patients with an MSMI diagnosis.

Outcomes
Total numbers, age-standardised rates (ASRs) of incidence, prevalence, mortality and disability-adjusted life years (DALYs) on MSMI from the GBD 2021 study and their estimated annual percentage changes (EAPCs) were the primary outcomes.

Results
There were 19 047 404 (95% uncertainty interval (UI) 14 608 563 to 24 086 486) annual incident cases, 2 376 876 (95% UI 1 678 868 to 3 421 377) prevalent cases at a single time point, 17 665 (95% UI 14 628 to 21 191) death cases and 1 144 233 (95% UI 956 988 to 1 352 034) DALYs of total MSMI in 2021. From 1990, the case number and ASRs of incidences and prevalence showed decreasing trends, while the case number and ASRs of mortality and DALYs gradually increased with time, reaching the peak in 2001, and then declined. In 2021, the ASRs of incidence, prevalence, mortality and DALYs sharply increased with age, which reached the peak in the 20–24 age group. The ASRs were decreased with increasing sociodemographic index (SDI). In 2021, it showed a positive correlation between EAPC and ASR of DALYs (r=0.3398, p

“Trying not to be seen”: a qualitative study exploring adolescent girls experiences seeking antenatal care in a Nairobi informal settlement

Background
Adolescent girls living in low-income urban informal settlements face unique challenges that elevate their susceptibility to early childbearing. However, there has been limited research attention, especially qualitative studies, on their use or non-use of antenatal care (ANC) services. Informed by the socioecological theory, we examined the obstacles to and facilitators of ANC services use among pregnant adolescent girls in a low-income urban informal settlement in Kenya.

Methods
The study adopted a qualitative explanatory design. We purposively selected 22 adolescent girls aged 13–19 who were either pregnant or had given birth, 10 parents and three health providers to participate in individual interviews. We employed inductive and deductive thematic analyses informed by socioecological theory to explain the barriers to enablers of antenatal services use among pregnant adolescent girls in low-income informal settlements.

Findings
Most adolescent girls interviewed faced barriers at multiple socioecological levels, resulting in delayed ANC initiation and fragmented engagement with services. At the intrapersonal level, girls grappled with internalised stigma and late pregnancy recognition and acceptance, often dismissing early signs due to fear or denial. Their young age and limited knowledge of maternal health left them terrified in fear, caught between societal judgement and the daunting prospect of confronting their condition. At the interpersonal level, societal stigma and discrimination pushed many into secrecy, hindering their access to antenatal services. However, parents, other family members, and health providers played a key role in enabling access to care by offering various forms of support to pregnant girls, including offering counselling and accompanying girls to clinics. At the organisational level, user fees and condescending health providers’ attitudes hindered ANC use. Yet, good patient-provider communication, privacy and confidentiality played a key role in enabling ANC attendance.

Conclusion
Pregnant adolescent girls face unique challenges that prevent them from accessing ANC early and completing the recommended number of visits. These challenges range from intrapersonal factors to interpersonal and organisational factors. Programmes to improve early initiation of ANC for pregnant adolescents should include interventions that address the social stigma associated with early and unintended pregnancy, promote family support and make health facilities responsive to the needs of pregnant girls.

Cohort profile: characterisation, determinants, mechanisms and consequences of the long-term effects of COVID-19 – providing the evidence base for health care services (CONVALESCENCE) in the UK

Purpose
The pathogenesis of the long-lasting symptoms which can follow an infection with the SARS-CoV-2 virus (‘long covid’) is not fully understood. The ‘COroNaVirus post-Acute Long-term EffectS: Constructing an evidENCE base’ (CONVALESCENCE) study was established as part of the Longitudinal Health and Wellbeing COVID-19 UK National Core Study. We performed a deep phenotyping case-control study nested within two cohorts (the Avon Longitudinal Study of Parents and Children and TwinsUK) as part of CONVALESCENCE.

Participants
From September 2021 to May 2023, 349 participants attended the CONVALESCENCE deep phenotyping clinic at University College London. Four categories of participants were recruited: cases of long covid (long covid(+)/SARS-CoV-2(+)), alongside three control groups: those with neither long covid symptoms nor evidence of prior COVID-19 (long covid(-)/SARS-CoV-2(-); control group 1), those who self-reported COVID-19 and had evidence of SARS-CoV-2 infection, but did not report long covid (long covid(-)/SARS-CoV-2(+); control group 2) and those who self-reported persistent symptoms attributable to COVID-19 but no evidence of SARS-CoV-2 infection (long covid(+)/SARS-CoV-2(-); control group 3). Remote wearable measurements were performed up until February 2024.

Findings to date
This cohort profile describes the baseline characteristics of the CONVALESCENCE cohort. Of the 349 participants, 141 (53±15 years old; 21 (15%) men) were cases, 89 (55±16 years old; 11 (12%) men) were in control group 1, 75 (49±15 years old; 25 (33%) men) were in control group 2 and 44 (55±16 years old; 9 (21%) men) were in control group 3.

Future plans
The study aims to use a multiorgan score calculated as the cumulative total for each of nine domains (ie, lung, vascular, heart, kidney, brain, autonomic function, muscle strength, exercise capacity and physical performance). The availability of data preceding acute COVID-19 infection in cohorts may help identify the consequences of infection independent of pre-existing subclinical disease and also provide evidence of determinants that influence the development of long covid.

Maintenance with niraparib in patients with stage III, stage IV, chemo-naïve recurrent or platinum-sensitive recurrent uterine serous carcinoma: study protocol for a phase II clinical trial

Introduction
Uterine serous carcinoma (USC) accounts for 40% of endometrial cancer-related deaths. The standard of care for stages III and IV USC yields a 20%–30% survival at 2 years and a 10%–20% survival at 3–5 years. Recent advances in the second-line treatment of advanced or recurrent USC are rapidly evolving. Targeted therapeutic approaches with the use of lenvatinib plus pembrolizumab, as well as the use of trastuzumab deruxtecan, offer new hope for successful second-line therapies for patients. However, further investigation into novel targeted therapeutic approaches is warranted, given the high burden of disease associated with this aggressive histological subtype. USC shares clinical and genomic similarities with epithelial ovarian cancer, suggesting a correlation with ‘BRCAness’. Niraparib, a potent PARP1 and PARP2 inhibitor, was shown to have a positive impact on platinum-sensitive recurrent ovarian cancer, regardless of the presence or absence of BRCA status. Our hypothesis is that patients with stage III, stage IV and platinum-sensitive recurrent USC receiving niraparib maintenance in addition to standard therapy for USC may have an improved progression-free survival.

Methods and analysis
Participating sites include the primary site, Northwell Health Zucker Cancer Centre, and secondary site, Rutgers Cancer Institute of NJ. Females over the age of 18 with stage III, stage IV or platinum-sensitive recurrent USC will be recruited and enrolled based on inclusion/exclusion criteria. 24 subjects will be enrolled during phase 1 and 21 subjects will be enrolled during phase 2, over a total of 3 years. Patients will receive an individualised dose of niraparib daily every 28 days per cycle for 1 year or until progression of disease. Follow-up of disease status will continue for 5 years poststudy treatment. This phase II clinical trial will employ a Simon two-stage minimax design to test the null hypothesis that the 1 year response rate is

Stakeholder perspectives on HPV vaccination uptake among Aboriginal and Torres Strait Islander adolescents via the school immunisation programmes in Queensland: a qualitative study

Introduction
Aboriginal and Torres Strait Islander women experience inequitable cervical cancer outcomes including higher incidence and mortality rates than other Australian women. Cervical cancer can be prevented through human papillomavirus (HPV) vaccination, which is primarily delivered through school immunisation programmes and found to be very effective. However, Aboriginal and Torres Strait Islander adolescents have lower rates of HPV vaccination uptake compared with non-Indigenous adolescents.

Objectives
This study explored the perspectives and experiences of HPV vaccination programme providers and school staff involved in the delivery of school-based HPV vaccination programmes for Aboriginal and Torres Strait Islander adolescents in Queensland.

Design
This qualitative project recruited 10 maximally diverse schools to participate. We purposively invited immunisation programme providers and school staff associated with delivering or supporting and used a snowballing approach to recruitment. We used an Indigenist Research approach and an ecological model for health to centre Aboriginal and Torres Strait Islander experiences and priorities.

Participants
We interviewed 18 immunisation programme providers and school staff involved in delivery between 2020 and 2022. Interview topics included programme delivery and processes, engagement with Aboriginal and Torres Strait Islander adolescents and caregivers, factors impacting uptake and completion, and suggestions for improvement.

Results
Stakeholders highlighted multilayered challenges navigating a school-based immunisation programme across health and education sectors, especially within the context of the COVID-19 pandemic. This included logistical barriers around programme coordination and scheduling, roles and responsibilities, and communication issues between schools, programme providers, caregivers and adolescents. Four themes were identified: (1) co-ordination of the clinic between schools and programme providers, (2) supporting Aboriginal and Torres Strait Islander families through the vaccination pathway, (3) HPV vaccination resources and (4) COVID-19 disruptions to HPV vaccination programme.

Conclusions
The findings suggest a need for better communication and coordination of the school-based clinic, including consideration of staff capacity and school resources; enhanced linkages with and support for Aboriginal and Torres Strait Islander student support staff and community organisations who play a critical role in supporting adolescents’ vaccination, and flexible methods of consent supported by culturally appropriate resources. These findings informed recommendations for improved practice and will contribute towards reaching Australia’s cervical cancer elimination targets.

Relational influences on help-seeking for mental health and substance use problems among people experiencing social marginalisation: a scoping review

Objectives
Understand the relational influences on help-seeking for mental health and substance use problems among people experiencing social marginalisation, with a focus on research applying social capital theory and social network analysis methods.

Design
Scoping review.

Data sources
EMBASE, Web of Science, Criminal Justice Abstracts and SocINDEX were searched up to June 2023, and Web of Science email alerts were used to capture any further publications up to June 2024.

Eligibility criteria
English-language, peer-reviewed publications that (1) focused on/discussed help-seeking for mental health or substance use problems; (2) included adults experiencing social marginalisation beyond sociodemographic factors; and (3) applied social capital theory or social network analysis methods.

Data extraction and synthesis
We extracted and charted data pertinent to review objectives and narratively synthesised results.

Results
Twenty-seven papers were included. Most (n=19) focused on the experiences of people who used drugs. Five specifically focused on help-seeking, four of which applied quantitative social network analysis, one was framed by network theories of social capital and one referred to social capital in interpreting findings. The remaining 22 papers discussed help-seeking while focused on different phenomena. Seven of these framed their approach with social capital, but none explicitly applied social capital to help-seeking. Eight papers used social network analysis, with four focused on help-seeking and seven using personal networks. Social/relational influences identified included: fear of losing social capital, the risks of high bonding capital, service providers as social capital, selective help-seeking, trust and network culture. Social capital, interconnected with the tight-knit bonds within marginalised groups, could deter help-seeking. Knowledge and attitudes towards help and help-seeking, shaped by past experiences and network cultures, influenced help-seeking and contributed to a cautious and selective approach.

Conclusion
Theoretical elaboration and empirical research are required to better appreciate the relational influences on help-seeking for mental health and substance use problems among people experiencing social marginalisation. Social capital may provide a useful theoretical approach. While social network analysis methods have been applied, they are under-utilised.

Feasibility randomised controlled trial to assess the delivery of a novel isometric exercise intervention for people diagnosed with uncomplicated stage 1 hypertension in the National Health Service: key quantitative findings

Objectives
The aim of this study was to determine the feasibility of delivering personalised isometric exercise (IE) for people with stage 1 hypertension. Is it feasible to deliver an isometric wall squat intervention in the National Health Service and what sample size is required to conduct an appropriately powered effectiveness randomised controlled trial (RCT)?

Design
Randomised controlled open-label multicentre feasibility study of IE compared with standard care in unmedicated people with stage 1 hypertension.

Setting
Initially, the study aimed to recruit through primary care, but this process coincided with the advent of the COVID-19 pandemic. Therefore, we shifted focus to direct-to-public advertising and delivery in secondary care.

Participants
People with unmedicated stage 1 hypertension aged over 18 able to perform IE were included. Patients were excluded if average home systolic blood pressure (sBP)

Predictors of sickness absence and intention to leave the profession among NHS staff in England during the COVID-19 pandemic: a prospective cohort study

Objectives
This study aims to determine key workforce variables (demographic, health and occupational) that predicted National Health Service (NHS) staff’s absence due to illness and expressed intention to leave their current profession.

Design, setting and participants
Staff from 18 NHS Trusts were surveyed between April 2020 and January 2021, and again approximately 12 months later.

Outcome measures
Logistic and linear regression were used to explore relationships between baseline exposures and four 12-month outcomes: absence due to COVID-19, absence due to non-COVID-19 illness, actively seeking employment outside current profession and regularly thinking about leaving current profession.

Results
22 555 participants (out of a possible 152 286 employees; 15%) completed the baseline questionnaire. 10 831 participants completed the short follow-up questionnaire at 12 months and 5868 also completed the long questionnaire; these participants were included in the analyses of sickness absence and intention to leave, respectively. 20% of participants took 5+ days of work absence for non-COVID-19 sickness in the 12 months between baseline and 12-month questionnaire; 14% took 5+ days of COVID-19-related sickness absence. At 12 months, 20% agreed or strongly agreed they were actively seeking employment outside their current profession; 24% thought about leaving their profession at least several times per week. Sickness absence (COVID-19 and non-COVID-19 related) and intention to leave the profession (actively seeking another role and thinking about leaving) were all more common among NHS staff who were younger, in a COVID-19 risk group, had a probable mental health disorder, and who did not feel supported by colleagues and managers.

Conclusions
Several factors affected both workforce retention and sickness absence. Of particular interest are the impact of colleague and manager support because they are modifiable. The NHS workforce is likely to benefit from training managers to speak with and support staff, especially those experiencing mental health difficulties. Further, staff should be given sufficient opportunities to form and foster social connections. Selection bias may have affected the presented results.

Burden of Cardiovascular Outcomes After SARS-CoV-2 Infection in South Korea and Japan: A Binational Population-Based Cohort Study

Circulation, Ahead of Print. BACKGROUND:Despite the significant global impact of the COVID-19 pandemic, limited studies have investigated the long-term cardiovascular sequelae of SARS-CoV-2 infection, particularly among Asian populations. This large-scale, population-based binational cohort study with long-term follow-up aimed to investigate the association between SARS-CoV-2 infection and the risk of cardiovascular events.METHODS:We used binational, large-scale, and population-based cohorts, including a Korean nationwide cohort (K-COV-N; discovery cohort; n=18 989 129) and a Japanese nationwide cohort (Japan Medical Data Center; validation cohort; n=12 218 680). Individuals aged 20 years or older were included from January 1, 2020, to December 31, 2022. We assessed the long-term risk of incident cardiovascular outcomes after SARS-CoV-2 infection. The primary outcome was the risk of cardiovascular diseases based onInternational Classification of Diseases, Tenth Revisioncode diagnosis. After propensity score–based overlap weighting, Cox proportional hazard models were used to estimate adjusted hazard ratios for cardiovascular outcomes. We assessed the time attenuation effect of cardiovascular outcomes after SARS-CoV-2 infection. Multiple subgroup analyses were conducted by 16 cardiovascular outcomes, COVID-19 severity, vaccination, and SARS-CoV-2 strain.RESULTS:In the overlap-weighted discovery cohort, 7 960 357 individuals were included (mean age, 48.52 years [SD, 9.33]; men, 4 283 878 [53.82%]). SARS-CoV-2 infection was associated with a long-term increased risk of overall cardiovascular outcomes (adjusted hazard ratio, 1.62 [95% CI, 1.60–1.64]), particularly ischemic heart disease (1.81 [95% CI, 1.77–1.84]), heart failure (1.79 [95% CI, 1.73–1.85]), cerebrovascular disorders (1.65 [95% CI, 1.60–1.69]), major adverse cardiovascular events (1.65 [95% CI, 1.60–1.70]), inflammatory heart diseases (1.53 [95% CI, 1.31–1.80]), dysrhythmia (1.44 [95% CI, 1.42–1.46]), and thrombotic disorders (1.42 [95% CI, 1.35–1.48]). The increased risk persisted up to 18 months, with the highest association observed for 1 to 6 months after infection. The risk of cardiovascular diseases was pronounced with COVID-19 severity; however, it decreased with the administration of complete vaccination and subsequent booster doses. A similar risk of cardiovascular outcomes existed across every SARS-CoV-2 era (pre-delta, delta, and omicron). Similar patterns were observed in the validation cohort. The absolute risk of cardiovascular disease events after SARS-CoV-2 infection remained remarkably low (2.12% versus 1.31% in the noninfected population), particularly stroke (0.24% versus 0.13%) and ischemic heart disease (0.73% versus 0.39%).CONCLUSIONS:This binational study observed associations between SARS-CoV-2 infection and cardiovascular events during extended follow-up across viral eras. Complete vaccination was linked to lower cardiovascular events. However, the absolute risk of cardiovascular disease events after SARS-CoV-2 infection remained remarkably low, particularly for stroke and ischemic heart disease. Although these findings suggest ongoing vigilance and preventive measures remain crucial, they should be interpreted within the context of these low absolute risks when considering long-term cardiovascular complications.
