HIV incidence among women engaging in sex work in sub-Saharan Africa: a systematic review and meta-analysis.

BACKGROUND: Women who engage in sex work in sub-Saharan Africa have a high risk of acquiring HIV infection. HIV incidence has declined among all women in sub-Saharan Africa, but trends among women who engage in sex work are poorly characterised. We synthesised data on HIV incidence among women who engage in sex work in sub-Saharan Africa and compared these with the total female population to understand relative incidence and trends over time. METHODS: We searched MEDLINE, Embase, Global Health, and Google Scholar from Jan 1, 1990, to Feb 28, 2024, and grey literature for studies that reported empirical estimates of HIV incidence among women who engage in sex work in any sub-Saharan Africa country. We calculated incidence rate ratios (IRRs) compared with total female population incidence estimates matched for age, district, and year, did a meta-analysis of IRRs, and used a continuous mixed-effects model to estimate changes in IRR over time. FINDINGS: From 32 studies done between 1985 and 2020, 2194 new HIV infections were observed among women who engage in sex work over 51 490 person-years. Median HIV incidence was 4·3 per 100 person years (IQR 2·8-7·0 per 100 person-years). Incidence among women who engage in sex work was eight times higher than matched total population women (IRR 7·8 [95% CI 5·1-11·8]), with larger relative difference in western and central Africa (19·9 [9·6-41·0]) than in eastern and southern Africa (4·9 [3·4-7·1]). There was no evidence that IRRs changed over time (IRR per 5 years: 0·9 [0·7-1·2]). INTERPRETATION: Across sub-Saharan Africa, HIV incidence among women who engage in sex work remains disproportionately high compared with the total female population. However, constant relative incidence over time indicates HIV incidence among women who engage in sex work has declined at a similar rate. Location-specific data for women who engage in sex work incidence are sparse, but improved surveillance and standardisation of incidence measurement approaches could fill these gaps. Sustained and enhanced HIV prevention for women who engage in sex work is crucial to address continuing inequalities and ensure declines in new HIV infections.

Improving support and planning ahead for older people with learning disabilities and family carers: a mixed-methods study.

Background: People with learning disabilities are living longer. Despite government policy to encourage people to lead supported lives in their community, family carers often maintain support due to dissatisfaction with services. This can lead to people moving from the family home in a crisis. Objectives: (1) Find out what is known about health needs and resources for older people with learning disabilities (aged ≥ 40 years); (2) identify exemplars of good services for older people with learning disabilities; (3) explore service exemplars through ethnographic case studies; (4) evaluate support for older people with learning disabilities and their families through co-producing and testing future planning tools and (5) co-produce recommendations and resources. Design and methods: Work package 1 rapid scoping reviews - three reviews focused on the health and social care needs of older people with learning disabilities and 'behaviours that challenge others', and family carers, and the co-ordination of support for this group. Work package 2 scoping and mapping exemplars of good practice - analysis of published service standards to assess excellence criteria, by mapping services, interviews (n = 30), survey (n = 9) and informal discussion with commissioners. Work package 3 ethnography of case studies of exemplar provision; independent supported living (n = 4); residential/nursing home (n = 2); day activities (n = 1), Shared Lives (n = 2). Fieldwork (20 days per model), interviews (n = 77) with older people with learning disabilities, family carers, support staff and commissioners. Work package 4 - co-producing and testing resources for older people with learning disabilities and their families involved interviews and focus groups with 36 people with learning disabilities, parents, and siblings, and experience-based co-design with 11 participants. Eight families evaluated the resources. Work package 5 - three stakeholder workshops co-produced service recommendations. Findings: The reviews confirmed an inadequate evidence base concerning the experiences and support of family carers and older people with learning disabilities and 'behaviours that challenge others'. Criteria of excellence were produced, and a shortlist of 15 services was identified for consideration in work package 3. The ethnographic work found that environmental, organisational and social factors were important, including supporting independence and choice about who people live with, matching staff to people, consistent relationships and adapting to ageing. Practices of institutionalisation were observed. In work package 4, we found that families were worried about the future and unsupported to explore options. 'Planning Ahead' cards and a booklet to record discussions were produced, and the evaluation was positively rated. Finally, formative discussion informed recommendations. Outputs include training packages, a carers' forum, a film, a podcast and academic papers. Conclusions: There is little focus on older people with learning disabilities and family carers. Services vary in their approach to planning for older-age support. Families are unsupported to plan, leaving people without choice. 'Behaviours that challenge others' was found to be unhelpful terminology. Recommendations: A new strategy is recommended for older people with learning disabilities and family carers that encompasses commissioning practices, professional input and peer learning, proactive support in ageing well and excellent service design. Limitations: The COVID-19 pandemic created recruitment challenges. Reliance on providers for recruitment resulted in a lack of diversity in work package 3. Families' plans, and therefore change, may be frustrated by insufficient service resources. Future work: Given the lack of focus in this area, there is a range of future work to consider: experiences of older people with learning disabilities from diverse ethnic backgrounds; supporting people to age and die 'in place'; best practice regarding designing/commissioning services, including housing; the role of social workers; access to nature; accessing mainstream support; and evaluation of the 'Planning Ahead' cards. Trial registration: This trial is registered as ISRCTN74264887.

People with learning disabilities are living longer, but most live with their families, who are also getting older. This is because there are not enough suitable places for people with learning disabilities to live, and family carers worry that the person will not get the right support and have a good life. Our research aimed to improve support for people with learning disabilities and their family carers to plan ahead for a good life. We focused on people who are labelled with 'behaviours that challenge others'. We read what has been written about this area. We looked for and found examples of excellent support for older people with learning disabilities. Researchers and people with learning disabilities and family carers spent time hanging out with people where they live or spend their days to see what support they get. Then we had three meetings with everyone involved and discussed our research findings with people with learning disabilities, family carers, and professionals. We found that people can be supported to live good lives as they grow older. This can be living alone or with people they choose, and it means having staff they like and who like them and being supported to be active. However, we found that ageing of people with learning disabilities is often ignored, and some people were not living good lives. We also found that the label of 'behaviours that challenge others' is unhelpful. We worked with people with learning disabilities and family carers to make a set of cards with pictures and questions to help people plan ahead for a good life. We produced resources and made recommendations to create a new plan for older people with learning disabilities to support people to lead good lives. This is very important because there is a lack of attention to and support for people with learning disabilities as they age.

Developing oral health services for people experiencing severe and multiple disadvantage: a case study from Southwest England.

People experiencing severe and multiple disadvantage (SMD) have disproportionately high levels of dental disease and tooth loss but have limited access to dental care. This paper presents an evidence-based case study of co-designing, implementing, evaluating and refining a community dental clinic for people experiencing SMD in the Southwest of England. It shares challenges, lessons, and solutions. Tailored interventions that coordinate flexible and responsive care are important for facilitating dental access for individuals experiencing SMD. Participatory approaches can deliver a range of impacts both on research and service development. No single fixed model of co-design can be applied in service development, and the choice will vary depending on local context, available resources and joint decision making. Through co-design, vulnerable populations such as those with SMD can shape dental services that are more acceptable, appropriate and responsive to their needs. This approach can also ensure long-term sustainability by bridging treatment pathway development and commissioning.

Improving Exposure Therapy: Rationale and Design of an International Consortium.

The Exposure Therapy Consortium (ETC) was established to advance the science and practice of exposure therapy. To encourage participation from researchers and clinicians, this article describes the organizational structure and activities of the ETC. Initial research working group experiences and a proof-of-principle study underscore the potential of team science and larger-scale collaborative research in this area. Clinical working groups have begun to identify opportunities to enhance access to helpful resources for implementing exposure therapy effectively. This article discusses directions for expanding the consortium's activities and its impact on a global scale.

A pilot feasibility and acceptability trial of an internet indicated prevention program for perfectionism to reduce eating disorder symptoms in adolescents.

PURPOSE: Perfectionism is a transdiagnostic risk factor for eating disorders. Treating perfectionism can reduce symptoms of eating disorders. No research has examined an indicated prevention trial using internet-based Cognitive-Behavioural Therapy for Perfectionism (ICBT-P) in adolescent girls at elevated risk for eating disorders. Our aim was to conduct a preliminary feasibility trial using a co-designed ICBT-P intervention. It was hypothesised that a higher proportion of participants in the ICBT-P condition would achieve reliable and clinically significant change on perfectionism, eating disorders, anxiety and depression, compared to waitlist control. METHODS: Twenty-one adolescent girls with elevated symptoms of eating disorders (M age = 16.14 years) were randomised to a 4-week online feasibility trial of a co-designed ICBT-P prevention program or waitlist control. Qualitative surveys were used to gain participant perspectives. RESULTS: The ICBT-P condition had a higher proportion of participants achieve reliable change and classified as recovered on perfectionism and symptoms of eating disorders and anxiety, compared to waitlist control. Qualitative findings indicated that 100% of participants found the program helpful. CONCLUSION: The results indicate ICBT-P is a feasible and acceptable program for adolescent girls with elevated eating disorder symptoms. Future research is required to examine outcomes in a randomised controlled trial. LEVEL OF EVIDENCE: Level III: Evidence obtained from well-designed cohort or case-control analytic studies. TRIAL REGISTRATION NUMBER: This trial was prospectively registered with Australian and New Zealand Clinical Trials Registry (ACTRN12620000951954P) on 23/09/2020.

Respiratory carriage of hypervirulent Klebsiella pneumoniae by indigenous populations of Malaysia.

Klebsiella pneumoniae is a Gram-negative Enterobacteriaceae that is classified by the World Health Organisation (WHO) as a Priority One ESKAPE pathogen. South and Southeast Asian countries are regions where both healthcare associated infections (HAI) and community acquired infections (CAI) due to extended-spectrum ß-lactamase (ESBL)-producing and carbapenem-resistant K. pneumoniae (CRKp) are of concern. As K. pneumoniae can also exist as a harmless commensal, the spread of resistance genotypes requires epidemiological vigilance. However there has been no significant study of carriage isolates from healthy individuals, particularly in Southeast Asia, and specially Malaysia. Here we describe the genomic analysis of respiratory isolates of K. pneumoniae obtained from Orang Ulu and Orang Asli communities in Malaysian Borneo and Peninsular Malaysia respectively. The majority of isolates were K. pneumoniae species complex (KpSC) 1 K. pneumoniae (n = 53, 89.8%). Four Klebsiella variicola subsp. variicola (KpSC3) and two Klebsiella quasipneumoniae subsp. similipneumoniae (KpSC4) were also found. It was discovered that 30.2% (n = 16) of the KpSC1 isolates were ST23, 11.3% (n = 6) were of ST65, 7.5% (n = 4) were ST13, and 13.2% (n = 7) were ST86. Only eight of the KpSC1 isolates encoded ESBL, but importantly not carbapenemase. Thirteen of the KpSC1 isolates carried yersiniabactin, colibactin and aerobactin, all of which harboured the rmpADC locus and are therefore characterised as hypervirulent. Co-carriage of multiple strains was minimal. In conclusion, most isolates were KpSC1, ST23, one of the most common sequence types and previously found in cases of K. pneumoniae infection. A proportion were hypervirulent (hvKp) however antibiotic resistance was low.

Risk factors and outcomes of bloodstream infection from a urinary source in kidney transplant recipients.

BACKGROUND: Bacteriuria is common among kidney transplant recipients (KTR). Risk factors and outcomes associated with bloodstream infection due to a urinary source (BSIU) in KTR are poorly understood. METHODS: This single center case-control study from 2010 to 2022 compared KTR with BSIU to those with bacteria without bloodstream infection (BU). Multivariable logistic regression identified BSIU risk factors, and Cox models assessed its impact on graft failure. RESULTS: Among 3435 patients, who underwent kidney transplantation at Emory Hospital, 757 (22%) developed bacteriuria, among whom 142 (18.8%) were BSIU. Male sex, presence of Escherichia coli, Klebsiella pneumoniae, or Pseudomonas species in urine culture, urethral stricture, neuromuscular bladder disorder, and history of diabetes-induced renal failure were independently associated with increased odds of BSIU (Male sex: aOR 2.29, 95% CI 1.52, 3.47, E. coli: aOR 5.14, 95% CI 3.02, 9.13; K. pneumoniae aOR 3.19, 95% CI 1.65, 6.27, Pseudomonas spp aOR 3.06, 95% CI 1.25, 7.18; urethral stricture: 4.10, 95% CI 1.63, 10.3, neuromuscular bladder disorder aOR 1.98, 95% CI 1.09, 3.53, diabetes: aOR 1.64, 95% CI 1.08, 2.49). BSIU was associated with increased hazard of graft failure (HR 1.52, 95% CI 1.05, 2.20). CONCLUSION: Close monitoring is warranted for male KTR with bacteriuria, those with urine cultures positive for Pseudomonas spp, K. pneumoniae, or E. coli, as well as KTR with a history of diabetes-induced renal failure, urethral stricture, or neuromuscular bladder disorder due to their risk for developing BSIU. Future research should explore strategies to mitigate BSIU risk in these high-risk KTR and reduce the associated risk of long-term graft failure.

Screening asthmatics for atopic status using the ALergy EXplorer (ALEX2) macroarray.

BACKGROUND: Screening asthma patients for atopy facilitates management. Since 2010, the core biomarker for screening asthma subjects for atopic status has been the qualitative Phadiatop. multi-aeroallergen screen. A more quantitative macroarray, the Allergy Explorer (ALEX2), shows promise as an alternative. OBJECTIVE: The study's goal was to examine the pros and cons of the use of ALEX2 in the screening of asthma patients for atopic status. METHODS: We evaluated the atopic (IgE-sensitization) status in asthmatic Amish and Hutterite farm children using the ImmunoCAP and ALEX2 assays in Phadiatop equivocal and positive subjects. RESULTS: All 42 asthmatic children were analyzed by Phadiatop and total serum IgE. Of these, 22 had a negative Phadiatop (<0.1 kUa/L) and total IgE <100 kU/L which defined them as non-atopic and they were excluded from ALEX2 testing. Of six children with equivocal Phadiatops (0.1-0.2 kUa/L-Group 1) and three children with a negative Phadiatop but total IgE >100 kUa/L (group 3), 44% (n = 4) had detectable IgE antibody by ALEX2 to mite, tree pollen, and other allergens not detected by Phadiatop, but confirmed by allergen-specific ImmunoCAP testing. In 11 Phadiatop positive subjects (>0.2 kUa/L-group 2), all but one were positive by ALEX2. IgE antibody specific for mold and rabbit aeroallergens matched their agricultural and pet exposure history. Three children were positive for IgE antibody to allergens in the profilin, nsLTP, or PR-10 cross-reactive protein families. CONCLUSION: Judicious use of ALEX2's enhanced specificity data not provided by the Phadiatop can aid in the interpretation of sensitization patterns and planning management of atopic asthmatics, but sensitization relevance must be confirmed by the patient's clinical history.

Comparison of Empirically Derived and Model-Based Estimates of Key Population HIV Incidence and the Distribution of New Infections by Population Group in Sub-Saharan Africa.

BACKGROUND: The distribution of new HIV infections among key populations, including female sex workers (FSWs), gay men and other men who have sex with men (MSM), and people who inject drugs (PWID) are essential information to guide an HIV response, but data are limited in sub-Saharan Africa (SSA). We analyzed empirically derived and mathematical model-based estimates of HIV incidence among key populations and compared with the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimates. METHODS: We estimated HIV incidence among FSW and MSM in SSA by combining meta-analyses of empirical key population HIV incidence relative to the total population incidence with key population size estimates (KPSE) and HIV prevalence. Dynamic HIV transmission model estimates of HIV incidence and percentage of new infections among key populations were extracted from 94 country applications of 9 mathematical models. We compared these with UNAIDS-reported distribution of new infections, implied key population HIV incidence and incidence-to-prevalence ratios. RESULTS: Across SSA, empirical FSW HIV incidence was 8.6-fold (95% confidence interval: 5.7 to 12.9) higher than total population female 15-39 year incidence, and MSM HIV incidence was 41.8-fold (95% confidence interval: 21.9 to 79.6) male 15-29 year incidence. Combined with KPSE, these implied 12% of new HIV infections in 2021 were among FSW and MSM (5% and 7% respectively). In sensitivity analysis varying KPSE proportions within 95% uncertainty range, the proportion of new infections among FSW and MSM was between 9% and 19%. Insufficient data were available to estimate PWID incidence rate ratios. Across 94 models, median proportion of new infections among FSW, MSM, and PWID was 6.4% (interquartile range 3.2%-11.7%), both much lower than the 25% reported by UNAIDS. CONCLUSION: Empirically derived and model-based estimates of HIV incidence confirm dramatically higher HIV risk among key populations in SSA. Estimated proportions of new infections among key populations in 2021 were sensitive to population size assumptions and were substantially lower than estimates reported by UNAIDS.

Measuring HIV Acquisitions Among Partners of Key Populations: Estimates From HIV Transmission Dynamic Models.

BACKGROUND: Key populations (KPs), including female sex workers (FSWs), gay men and other men who have sex with men (MSM), people who inject drugs (PWID), and transgender women (TGW) experience disproportionate risks of HIV acquisition. The UNAIDS Global AIDS 2022 Update reported that one-quarter of all new HIV infections occurred among their non-KP sexual partners. However, this fraction relied on heuristics regarding the ratio of new infections that KPs transmitted to their non-KP partners to the new infections acquired among KPs (herein referred to as "infection ratios"). We recalculated these ratios using dynamic transmission models. SETTING: One hundred seventy-eight settings (106 countries). METHODS: Infection ratios for FSW, MSM, PWID, TGW, and clients of FSW were estimated from 12 models for 2020. RESULTS: Median model estimates of infection ratios were 0.7 (interquartile range: 0.5-1.0; n = 172 estimates) and 1.2 (0.8-1.8; n = 127) for acquisitions from FSW clients and transmissions from FSW to all their non-KP partners, respectively, which were comparable with the previous UNAIDS assumptions (0.2-1.5 across regions). Model estimates for female partners of MSM were 0.5 (0.2-0.8; n = 20) and 0.3 (0.2-0.4; n = 10) for partners of PWID across settings in Eastern and Southern Africa, lower than the corresponding UNAIDS assumptions (0.9 and 0.8, respectively). The few available model estimates for TGW were higher [5.1 (1.2-7.0; n = 8)] than the UNAIDS assumptions (0.1-0.3). Model estimates for non-FSW partners of FSW clients in Western and Central Africa were high (1.7; 1.0-2.3; n = 29). CONCLUSIONS: Ratios of new infections among non-KP partners relative to KP were high, confirming the importance of better addressing prevention and treatment needs among KP as central to reducing overall HIV incidence.

Natural reversion promotes LPS elongation in an attenuated Coxiella burnetii strain.

Lipopolysaccharide (LPS) phase variation is a critical aspect of virulence in many Gram-negative bacteria. It is of particular importance to Coxiella burnetii, the biothreat pathogen that causes Q fever, as in vitro propagation of this organism leads to LPS truncation, which is associated with an attenuated and exempted from select agent status (Nine Mile II, NMII). Here, we demonstrate that NMII was recovered from the spleens of infected guinea pigs. Moreover, these strains exhibit a previously unrecognized form of elongated LPS and display increased virulence in comparison with the initial NMII strain. The reversion of a 3-bp mutation in the gene cbu0533 directly leads to LPS elongation. To address potential safety concerns, we introduce a modified NMII strain unable to produce elongated LPS.

HIV prevalence in transgender populations and cisgender men who have sex with men in sub-Saharan Africa 2010-2022: a meta-analysis.

Introduction: The Global AIDS Strategy 2021-2026 calls for equitable and equal access to HIV prevention and treatment programmes for all populations to reduce HIV incidence and end HIV/AIDS as a public health threat by 2030. Transgender populations (TGP), including transmen (TGM) and transwomen (TGW) are populations that have been marginalised and are at high risk of HIV infection in sub-Saharan Africa (SSA). Limited surveillance data on HIV among TGP are available in the region to guide programmatic responses and policymaking. Surveillance data on cisgender men who have sex with men (cis-MSM) are comparatively abundant and may be used to infer TGP HIV prevalence. Methods: Data from key population surveys conducted in SSA between 2010-2022 were identified from existing databases and survey reports. Studies that collected HIV prevalence on both TGP and cis-MSM populations were analysed in a random effect meta-analysis to estimate the ratio of cis-MSM:TGW HIV prevalence. Results: Eighteen studies were identified encompassing 8,052 TGW and 19,492 cis-MSM. TGW HIV prevalence ranged from 0-71.6% and cis-MSM HIV prevalence from 0.14-55.7%. HIV prevalence in TGW was 50% higher than in cis-MSM (prevalence ratio (PR) 1.50 95% CI 1.26-1.79). TGW HIV prevalence was highly correlated with year/province-matched cis-MSM HIV prevalence (R2 = 0.62), but poorly correlated with year/province-matched total population HIV prevalence (R2 = 0.1). Five TGM HIV prevalence estimates were identified ranging from 1-24%. Insufficient TGM data were available to estimate cis-MSM:TGM HIV prevalence ratios. Conclusion: Transgender women experience a significantly greater HIV burden than cis-MSM in SSA. Bio-behavioural surveys designed and powered to measure determinants of HIV infection, treatment coverage, and risk behaviours among transgender populations, distinct from cis-MSM, will improve understanding of HIV risk and vulnerabilities among TGP and support improved programmes.

HIV incidence among women engaging in sex work in sub-Saharan Africa: a systematic review and meta-analysis.

Introduction: HIV incidence among women in sub-Saharan Africa (SSA) has declined steadily, but it is unknown whether new infections among women who engage in sex work (WESW) have declined at a similar rate. We synthesised estimates of HIV incidence among WESW in SSA and compared these to the wider female population to understand levels and trends in incidence over time. Methods: We searched Medline, Embase, Global Health, Popline, Web of Science, and Google Scholar from January 1990 to October 2022, and grey literature for estimates of HIV incidence among WESW in SSA. We included studies reporting empirical estimates in any SSA country. We calculated incidence rate ratios (IRR) compared to age-district-year matched total female population incidence estimates. We conducted a meta-analysis of IRRs and used a continuous mixed-effects model to estimate changes in IRR over time. Results: From 32 studies between 1985 and 2020, 2,194 new HIV infections were observed in WESW over 51,000 person-years (py). Median HIV incidence was 4.3/100py (IQR 2.8-7.0/100py), declining from a median of 5.96/100py between 1985 and 1995 to a median of 3.2/100py between 2010 and 2020. Incidence among WESW was nine times higher than in matched total population women (RR 8.6, 95%CI: 5.7-12.9), and greater in Western and Central Africa (RR 22.4, 95%CI: 11.3-44.3) than in Eastern and Southern Africa (RR 5.3, 95%CI: 3.7-7.6). Annual changes in log IRRs were minimal (-0.1% 95%CI: -6.9 to +6.8%). Conclusions: Across SSA, HIV incidence among WESW remains disproportionately high compared to the total female population but showed similar rates of decline between 1990 and 2020. Improved surveillance and standardisation of approaches to obtain empirical estimates of sex worker incidence would enable a clearer understanding of whether we are on track to meet global targets for this population and better support data-driven HIV prevention programming.

Characterization of Proteus mirabilis and associated plasmids isolated from anaerobic dairy cattle manure digesters.

Proteus mirabilis is an opportunistic pathogen associated with a variety of human infections, including urinary tract infections. The prevalence of P. mirabilis in foods of animal origin and in the manure by-products created in animal production is not well documented. Further, the prevalence and persistence of extended-spectrum cephalosporin (ESC) resistant P. mirabilis is largely unknown. In this study, we characterized ESC-resistant P. mirabilis recovered from various stages of dairy manure anaerobic digestion. Isolates were screened by PCR for blaCTX-M, blaCMY and blaSHV, and antimicrobial susceptibility testing was performed. Fifty-six P. mirabilis carrying CTX-M were sequenced with short and long read sequencing technologies, and the assembled chromosomes and plasmids were compared. ESC-resistant Proteus was found in four of the six manure digesters, an indication that not all digesters were colonized with resistant strains. Both CTX-M-1 and CTX-M-15 plasmids were found in P. mirabilis isolates. Transfer of plasmid DNA by conjugation was also explored, with ESC-resistance plasmids able to transfer to Escherichia coli at high frequency. We concluded that P. mirabilis can harbour and transfer ESC-resistance genes and plasmids, and may be an overlooked reservoir of antimicrobial resistance.

Stakeholder integration predicts better outcomes from groundwater sustainability policy.

Natural resources policies that promote sustainable management are critical for protecting diverse stakeholders against depletion. Although integrating diverse stakeholders into these policies has been theorized to improve protection, empirical evidence is lacking. Here, we evaluate 108 Sustainability Plans under California's Sustainable Groundwater Management Act to quantify how well stakeholders are integrated into plans and protected from groundwater depletion. We find that the majority of Sustainability Plans do not integrate or protect the majority of their stakeholders. Nevertheless, our results show that when stakeholders are more integrated into a Sustainability Plan, they are more likely to be protected, particularly for those that lack formal access to decision-making processes. Our findings provide strong empirical evidence that integrating diverse stakeholders into sustainability planning is beneficial for stakeholders who are vulnerable to the impacts of natural resource depletion.

Consensus recommendations for the assessment and treatment of perinatal obsessive-compulsive disorder (OCD): A Delphi study.

The perinatal period is one of increased vulnerability to parents experiencing the onset of, or an increase of existing, obsessive-compulsive disorder (OCD) symptoms. Existing OCD and perinatal mental health best practice guidelines do not detail specific considerations relevant to OCD in the perinatal period ('Perinatal OCD'). Perinatal OCD risks being undiagnosed or misdiagnosed, and subsequently untreated or mistreated, with potential negative impacts for individuals and families experiencing this problem, highlighting the importance of specific guidance. This study employed a modified Delphi survey methodology to establish recommended best practice for the assessment and treatment of perinatal OCD. A literature review identified 103 initial best practice recommendations, and participants suggested 18 further recommendations. These recommendations were rated for importance over three survey rounds by two expert panels, comprising of 15 professionals with clinical or research expertise in perinatal OCD and 14 consumers with lived experience of perinatal OCD. One-hundred and two statements were endorsed for inclusion in the final set of recommendations for clinical best practice with perinatal OCD. These recommendations inform practice across eight themes; psychoeducation, screening, assessment, differential diagnosis, case care considerations, treatment, partners & families, and culture & diversity. This novel study is the first to collate and outline a set of clinical best practice recommendations, developed using the consensus perspectives of both individuals with lived experience and professionals with relevant expertise, for supporting individuals with perinatal OCD and their families. Differences between panel perspectives, and directions for future research are also discussed.

Single cell profiling at the maternal-fetal interface reveals a deficiency of PD-L1+ non-immune cells in human spontaneous preterm labor.

The mechanisms that underlie the timing of labor in humans are largely unknown. In most pregnancies, labor is initiated at term (≥ 37 weeks gestation), but in a signifiicant number of women spontaneous labor occurs preterm and is associated with increased perinatal mortality and morbidity. The objective of this study was to characterize the cells at the maternal-fetal interface (MFI) in term and preterm pregnancies in both the laboring and non-laboring state in Black women, who have among the highest preterm birth rates in the U.S. Using mass cytometry to obtain high-dimensional single-cell resolution, we identified 31 cell populations at the MFI, including 25 immune cell types and six non-immune cell types. Among the immune cells, maternal PD1+ CD8 T cell subsets were less abundant in term laboring compared to term non-laboring women. Among the non-immune cells, PD-L1+ maternal (stromal) and fetal (extravillous trophoblast) cells were less abundant in preterm laboring compared to term laboring women. Consistent with these observations, the expression of CD274, the gene encoding PD-L1, was significantly depressed and less responsive to fetal signaling molecules in cultured mesenchymal stromal cells from the decidua of preterm compared to term women. Overall, these results suggest that the PD1/PD-L1 pathway at the MFI may perturb the delicate balance between immune tolerance and rejection and contribute to the onset of spontaneous preterm labor.
