Identifying missed opportunities for hepatitis C virus antenatal testing and diagnosis in England.

New case-finding opportunities are needed to achieve hepatitis C virus (HCV) elimination in England by the year 2030. HCV antenatal testing is not offered universally in England but is recommended for women with risk factors for HCV (e.g. injecting drug use, being born in a high-prevalence country). The aim of this analysis was to investigate the missed opportunities for HCV antenatal testing among women who had given birth and were subsequently diagnosed with HCV at some time after childbirth. By linking data on live births (2010-2020) to laboratory reports of HCV diagnoses (1995-2021), we identified all women who were diagnosed with HCV after the date of their first childbirth. This group was considered to potentially have experienced a missed opportunity for HCV antenatal testing; HCV-RNA testing and treatment outcomes were also obtained for these women. Of the 32,295 women who gave birth between 2010 and 2020 with a linked diagnosis of HCV (median age: 34 years, 72.1% UK-born), over half (n = 17,123) were diagnosed after childbirth. In multivariable analyses, the odds of being diagnosed with HCV after childbirth were higher in those of Asian Bangladeshi, Black African or Chinese ethnicity and among those born in Africa. Over four-fifths (3510/4260) of those eligible for treatment were linked to treatment, 30.7% (747/2435) of whom had a liver scarring level of at least moderate and 9.4% (228/2435) had cirrhosis. Given the potential opportunity to identify cases of HCV with targeted case-finding through antenatal services, universal opt-out testing should be considered in these settings.

Improving 1-Year Mortality Following Intensive Care Unit Admission in Adults with HIV: A 20-Year Observational Study.

BACKGROUND: Despite widespread use of combination antiretroviral therapy, people with HIV (PWH) continue to have an increased risk of admission to and mortality in the intensive care unit (ICU). Mortality risk after hospital discharge is not well described. Using retrospective data on adult PWH (≥18 years) admitted to ICU from 2000-2019 in an HIV-referral centre, we describe trends in 1-year mortality after ICU admission. METHODS: One-year mortality was calculated from index ICU admission to date of death; with follow-up right-censored at day 365 for people remaining alive at 1 year, or day 7 after ICU discharge if lost-to-follow-up after hospital discharge. Cox regression was used to describe the association with calendar year before and after adjustment for patient characteristics (age, sex, Acute Physiology and Chronic Health Evaluation II [APACHE II] score, CD4+ T-cell count, and recent HIV diagnosis) at ICU admission. Analyses were additionally restricted to those discharged alive from ICU using a left-truncated design, with further adjustment for respiratory failure at ICU admission in these analyses. RESULTS: Two hundred and twenty-one PWH were admitted to ICU (72% male, median [interquartile range] age 45 [38-53] years) of whom 108 died within 1-year (cumulative 1-year survival: 50%). Overall, the hazard of 1-year mortality was decreased by 10% per year (crude hazard ratio (HR): 0.90 (95% confidence interval: 0.87-0.93)); the association was reduced to 7% per year (adjusted HR: 0.93 (0.89-0.98)) after adjustment. Conclusions were similar among the subset of 136 patients discharged alive (unadjusted: 0.91 (0.84-0.98); adjusted 0.92 (0.84, 1.02)). CONCLUSIONS: Between 2000 and 2019, 1-year mortality after ICU admission declined at this ICU. Our findings highlight the need for multi-centre studies and the importance of continued engagement in care after hospital discharge among PWH.

Exploring the concept of unmet need within sexual and reproductive health in England: A qualitative Delphi exercise.

BACKGROUND: Unmet need within sexual and reproductive health (SRH) is a concept that is difficult to define and measure. This qualitative Delphi exercise was used to ascertain the opinions of SRH professionals on the conceptualisation and measurement of unmet need within SRH. METHODS: This exercise was carried out in two rounds. In the first round, respondents responded narratively to three prompts, which were then used to create a series of statements. In the second round, participants responded narratively to the statements created in the first round. Responses from both rounds were then coded and analysed thematically. RESULTS: Participants felt that an understanding of unmet need is an important part of SRH service design and provision, and believed that certain populations are often underrepresented within the datasets that are used to assess unmet need. Many respondents felt that a full understanding of unmet need within SRH would only come from involvement of relevant stakeholders in the process of investigating unmet need, and that qualitative methods may also have a role to play in gaining a more holistic understanding of unmet need within SRH. CONCLUSIONS: Respondents within this study felt that unmet need is complex concept that has a significant impact on service delivery and the outcomes and experiences of the most vulnerable populations. We need to improve our understanding of unmet need and prioritise stakeholder voices if we want to create interventions that address unmet need within SRH.

Inequalities in sexual and reproductive outcomes among women aged 16-24 in England (2012-2019).

BACKGROUND: Women aged 16-24 in England have a high burden of sexual and reproductive morbidity, with particularly poor outcomes among people living in more deprived areas (including racially minoritised populations). This analysis used national data to examine the disparities within sexual and reproductive outcomes among this population and to assess whether the patterns of inequality were consistent across all outcomes. METHODS: Within this ecological study, univariable and multivariable Poisson regression analyses of neighbourhood-level data from national data sets were carried out to investigate the relationships of deprivation and ethnicity with each of six dependent variables: gonorrhoea and chlamydia testing rates, gonorrhoea and chlamydia test positivity rates, and abortion and repeat abortion rates. RESULTS: When comparing Index of Multiple Deprivation (IMD) decile 1 (most deprived) and IMD decile 10 (least deprived), chlamydia (RR 0.65) and gonorrhoea (0.79) testing rates, chlamydia (0.70) and gonorrhoea (0.34) positivity rates, abortion rates (0.45) and repeat abortion rates (0.72) were consistently lower in IMD decile 10 (least deprived). Similarly, chlamydia (RR 1.24) and gonorrhoea positivity rates (1.92) and repeat abortion rates (1.31) were higher among black women than white women. Results were similar when both ethnicity and deprivation were incorporated into multivariable analyses. CONCLUSION: We found similar patterns of outcome inequality across a range of sexual and reproductive outcomes, despite multiple differences in the drivers of each outcome. Our analysis suggests that there are broad structural causes of inequality across sexual and reproductive health that particularly impact the health of deprived and black populations.

The Impact of Time between Booster Doses on Humoral Immune Response in Solid Organ Transplant Recipients Vaccinated with BNT162b2 Vaccines.

As solid organ transplant (SOT) recipients remain at risk of severe outcomes after SARS-CoV-2 infections, vaccination continues to be an important preventive measure. In SOT recipients previously vaccinated with at least three doses of BNT162b2, we investigated humoral responses to BNT162b2 booster doses. Anti-SARS-CoV-2 receptor binding domain (RBD) immunoglobulin G (IgG) was measured using an in-house ELISA. Linear mixed models were fitted to investigate the change in the geometric mean concentration (GMC) of anti-SARS-CoV-2 RBD IgG after vaccination in participants with intervals of more or less than six months between the last two doses of vaccine. We included 107 SOT recipients vaccinated with a BNT162b2 vaccine. In participants with an interval of more than six months between the last two vaccine doses, we found a 1.34-fold change in GMC per month (95% CI 1.25-1.44), while we found a 1.09-fold change in GMC per month (95% CI 0.89-1.34) in participants with an interval of less than six months between the last two vaccine doses, resulting in a rate ratio of 0.82 (95% CI 0.66 to 1.01, p = 0.063). In conclusion, the administration of identical COVID-19 mRNA vaccine boosters within six months to SOT recipients may result in limited humoral immunogenicity of the last dose.
