RESUMO

BACKGROUND: Globally, 2-14% of women experience intimate partner violence (IPV) during pregnancy. Timely response to IPV is critical to mitigate related adverse health outcomes. Barriers to accessing limited IPV support services are pervasive in low- and middle-income countries (LMICs), such as Ethiopia; key barriers include mistrust, stigmatization, and self-blame, and discourage women from disclosing their experiences. Infection control measures for COVID-19 have the potential to further disrupt access to IPV services. METHODS: In-depth qualitative interviews were undertaken from October-November 2020 with 24 women who experienced IPV during recent pregnancy to understand the needs and unmet needs of IPV survivors in Ethiopia amid the COVID-19 pandemic. Trained qualitative interviewers used a structured note-taking tool to allow probing of experiences, while permitting rapid analysis for timely results. Inductive thematic analysis identified emergent themes, which were organized into matrices for synthesis. RESULTS: Qualitative themes center around knowledge of IPV services; experiences of women in seeking services; challenges in accessing services; the impact of COVID-19 on resource access; and persistent unmet needs of IPV survivors. Notably, few women discussed the violence they experienced as unique to pregnancy, with most referring to IPV over an extended period, both prior to and during COVID-19 restrictions. The majority of IPV survivors in our study heavily relied on their informal network of family and friends for protection and assistance in resolving the violence. Though formal IPV services remained open throughout the pandemic, restrictions resulted in the perception that services were not available, and this perception discouraged survivors from seeking help. Survivors further identified lack of integrated and tailored services as enduring unmet needs. CONCLUSIONS: Results reveal a persistent low awareness and utilization of formal IPV support and urge future policy efforts to address unmet needs through expansion of services by reducing socio-cultural barriers. COVID-19 impacted access to both formal and informal support systems, highlighting needs for adaptable, remote service delivery and upstream violence prevention. Public health interventions must strengthen linkages between formal and informal resources to fill the unmet needs of IPV survivors in receiving medical, psychosocial, and legal support in their home communities.

RESUMO

Ensuring access to sexual and reproductive health (SRH) services for adolescents is a global priority, given the detrimental health and economic impact of unintended pregnancies. To examine whether and how COVID-19 affected access to SRH services, we use mixed-methods data from young men and women in Nairobi, Kenya to identify those at greatest risk of contraceptive disruptions during COVID-19 restrictions. Analyses utilize cross-sectional data collected from August to October 2020 from an existing cohort of youth aged 16-26. Unadjusted and adjusted logistic regression examined sociodemographic, contraceptive, and COVID-19-related correlates of contraceptive disruption among users of contraception. Qualitative data were collected concurrently via focus group discussions (n = 64, 8 groups) and in-depth interviews (n = 20), with matrices synthesizing emergent challenges to obtaining contraception by gender. Among those using contraception, both young men (40.4%) and young women (34.6%) faced difficulties obtaining contraception during COVID-19. Among young men, difficulty was observed particularly for those unable to meet their basic needs (aOR = 1.60; p = 0.05). Among young women, risk centered around those with multiple partners (aOR = 1.91; p = 0.01), or who procured their method from a hospital (aOR = 1.71; p = 0.04) or clinic (aOR = 2.14; p = 0.03). Qualitative data highlight economic barriers to obtaining contraceptives, namely job loss and limited supply of free methods previously available. Universal access to a variety of contraceptive methods during global health emergencies, including long-acting reversible methods, is an essential priority to help youth avert unintended pregnancies and withstand periods of disruptions to services. Non-judgmental, youth-friendly services must remain accessible throughout the pandemic into the post-COVID-19 period.

RESUMO

PROBLEM: Violence in Chicago has been persistently high in low-income communities of color. Recent attention has focused on how structural inequities weaken protective factors that help keep communities healthy and safe. Spikes in community violence seen in Chicago since the COVID-19 pandemic further expose the lack of social service, health care, economic, and political safety nets in low-income communities and the apparent dearth of faith in those systems. APPROACH: The authors contend that a comprehensive, collaborative approach to violence prevention that prioritizes treatment and community partnerships is needed to address social determinants of health and structural characteristics that often provide the context for interpersonal violence. One strategy to address decreasing faith in systems like hospitals is foregrounding frontline paraprofessional prevention workers who possess cultural capital based on their experiences navigating interpersonal and structural violence. Hospital-based violence intervention programs help professionalize these prevention workers by providing a framework for patient-centered crisis intervention and assertive case management. The authors describe how the Violence Recovery Program (VRP), a multidisciplinary hospital-based violence intervention model, leverages the cultural capital of credible messengers to use teachable moments to promote trauma-informed care to violently injured patients, assess their immediate risk for reinjury and retaliation, and connect them to wrap-around services to help aid comprehensive recovery. OUTCOMES: Violence recovery specialists have engaged over 6,000 victims of violence since the program's launch in 2018. Three-quarters of patients expressed social determinants of health needs. Over the past year, specialists have connected over one-third of engaged patients to mental health referrals and community-based social services. NEXT STEPS: High violence rates in Chicago limited case management opportunities in the emergency room. In fall 2022, the VRP began to establish collaborative agreements with community-based street outreach programs and medical-legal partnerships to address structural determinants of health.

RESUMO

Background: Access to menstrual hygiene products enables positive health for adolescent girls and young women (AGYW). Among AGYW in Nairobi, Kenya, this prospective mixed-methods study characterised menstrual health product-access challenges at two time points during the COVID-19 pandemic; assessed trajectories over the pandemic; and examined factors associated with product-access trajectories. Methods: Data were collected from an AGYW cohort in August-October 2020 and March-June 2021 (n=591). The prevalence of menstrual health product-access challenges was calculated per timepoint, with trajectories characterizing product-access challenges over time. Logistic regression models examined associations with any product-access challenge throughout the pandemic; multinomial and logistic regressions further assessed factors associated with trajectories. Qualitative data contextualize results. Findings: In 2020, 52·0% of AGYW experienced a menstrual health product-access challenge; approximately six months later, this proportion dropped to 30·3%. Product-access challenges during the pandemic were heightened for AGYW with secondary or lower education (aOR=2·40; p<0·001), living with parents (aOR=1·86; p=0·05), not the prime earner (aOR=2·27; p=0·05); and unable to meet their basic needs (aOR=2·25; p<0·001). Between timepoints, 38·0% experienced no product-access challenge and 31·7% resolved, however, 10·2% acquired a challenge and 20·1% experienced sustained challenges. Acquired product-access challenges, compared to no challenges, were concentrated among those living with parents (aOR=3·21; p=0·05); multinomial models further elucidated nuances. Qualitative data indicate deprioritization of menstrual health within household budgets as a contributor. Interpretation: Menstrual health product-access challenges are prevalent among AGYW during the pandemic; barriers were primarily financial. Results may reflect endemic product-access gaps amplified by COVID-specific constraints. Ensuring access to menstrual products is essential to ensure AGYW's health needs. Funding: This work was supported, in whole, by the Bill & Melinda Gates Foundation [010481].

RESUMO

OBJECTIVES: This multimethods study aimed to: (1) compare the prevalence of intimate partner violence (IPV) during pregnancy pre-COVID-19 and during the COVID-19 pandemic using quantitative data and (2) contextualise pregnant women's IPV experiences during the COVID-19 pandemic through supplemental interviews. DESIGN: Quantitative analyses use data from Performance Monitoring for Action-Ethiopia, a cohort of 2868 pregnant women that collects data at pregnancy, 6 weeks, 6 months and 1-year postpartum. Following 6-week postpartum survey, in-depth semistructured interviews contextualised experiences of IPV during pregnancy with a subset of participants (n=24). PARTICIPANTS: All pregnant women residing within six regions of Ethiopia, covering 91% of the population, were eligible for the cohort study (n=2868 completed baseline survey). Quantitative analyses were restricted to the 2388 women with complete 6-week survey data (retention=82.7%). A purposive sampling frame was used to select qualitative participants on baseline survey data, with inclusion criteria specifying completion of quantitative 6-week interview after the onset of the COVID-19 pandemic, and indication of IPV experience. INTERVENTIONS: A State of Emergency in Ethiopia was declared in response to the COVID-19 pandemic approximately halfway through 6-week postpartum interview, enabling a natural experiment (n=1405 pre-COVID-19; n=983 during-COVID-19). PRIMARY OUTCOME MEASURES: IPV during pregnancy was assessed via the 10-item Revised Conflict and Tactics Scale. RESULTS: 1-in-10 women experienced any IPV during pregnancy prior to COVID-19 (10.5%), and prevalence of IPV during pregnancy increased to 15.1% during the COVID-19 pandemic (aOR=1.51; p=0.02). Stratified by residence, odds of IPV during the pandemic increased for urban women only (aOR=2.09; p=0.03), however, IPV prevalence was higher in rural regions at both time points. Qualitative data reveal COVID-19-related stressors, namely loss of household income and increased time spent within the household, exacerbated IPV. CONCLUSIONS: These multimethods results highlight the prevalent, severe violence that pregnant Ethiopian women experience, with pandemic-related increases concentrated in urban areas. Integration of IPV response and safety planning across the continuum of care can mitigate impact.

RESUMO

The objective of this evaluation was to assess the use of public health detailing in a pilot program to increase Expedited Partner Therapy (EPT) uptake among community-based providers in two Maryland jurisdictions. Public health detailing is a method designed to raise awareness and increase implementation of evidence-based clinical practices by delivering educational content via one-on-one meetings with providers. EPT is a voluntary clinical practice of treating all sexual partners of patients diagnosed with STIs by prescribing medications without the provider first examining said sexual partners. The aim of EPT is to prevent STI reinfection and reduce further transmission. From April 2017 to March 2019, detailers visited community-based health care practice sites to conduct EPT detailing with providers. The effectiveness of this program was evaluated by comparing provider responses from pre- to post-detailing surveys, administered six months after detailing. Survey responses assessed EPT awareness and practices, barriers to implementation, and satisfaction with detailing. The proportion of providers (170) aware of EPT for treating chlamydia and gonorrhea increased from 61.7% (114) to 99.4% (169) (p-value < 0.001). The proportion who reported prescribing EPT increased from 63.2% (72) to 86.4% (146) (p-value < 0.001). Providers reporting no barriers to prescribing EPT increased from 30.6% (52) to 55.9% (95) (p-value < 0.001). Most providers were satisfied with detailing, 95.5% (164), and 95.3% (162) preferred this method to communicate about public health measures. Detailing appears to be a strategy to improve provider awareness of EPT, increase EPT implementation, and reduce barriers to prescribing EPT.

RESUMO

Enamel-renal syndrome (ERS) is an autosomal recessive disorder characterized by severe enamel hypoplasia, failed tooth eruption, intrapulpal calcifications, enlarged gingiva, and nephrocalcinosis. Recently, mutations in FAM20A were reported to cause amelogenesis imperfecta and gingival fibromatosis syndrome (AIGFS), which closely resembles ERS except for the renal calcifications. We characterized three families with AIGFS and identified, in each case, recessive FAM20A mutations: family 1 (c.992G>A; g.63853G>A; p.Gly331Asp), family 2 (c.720-2A>G; g.62232A>G; p.Gln241_Arg271del), and family 3 (c.406C>T; g.50213C>T; p.Arg136* and c.1432C>T; g.68284C>T; p.Arg478*). Significantly, a kidney ultrasound of the family 2 proband revealed nephrocalcinosis, revising the diagnosis from AIGFS to ERS. By characterizing teeth extracted from the family 3 proband, we demonstrated that FAM20A(-/-) molars lacked true enamel, showed extensive crown and root resorption, hypercementosis, and partial replacement of resorbed mineral with bone or coalesced mineral spheres. Supported by the observation of severe ectopic calcifications in the kidneys of Fam20a null mice, we conclude that FAM20A, which has a kinase homology domain and localizes to the Golgi, is a putative Golgi kinase that plays a significant role in the regulation of biomineralization processes, and that mutations in FAM20A cause both AIGFS and ERS.

RESUMO

Amelogenesis imperfecta (AI) is a group of inherited conditions featuring isolated enamel malformations. About 5% of AI cases show an X-linked pattern of inheritance, which are caused by mutations in AMELX. In humans there are two, non-allelic amelogenin genes: AMELX (Xp22.3) and AMELY (Yp11.2). About 90% of amelogenin expression is from AMELX, which is nested within intron 1 of the gene encoding Rho GTPase activating protein 6 (ARHGAP6). We recruited two AI families and determined that their disease-causing mutations were partial deletions in ARHGAP6 that completely deleted AMELX. Affected males in both families had a distinctive enamel phenotype resembling "snow-capped" teeth. The 96,240 bp deletion in family 1 was confined to intron 1 of ARHGAP6 (g.302534_398773del96240), but removed alternative ARHGAP6 promoters 1c and 1d. Analyses of developing teeth in mice showed that ARHGAP6 is not expressed from these promoters in ameloblasts. The 52,654 bp deletion in family 2 (g.363924_416577del52654insA) removed ARHGAP6 promoter 1d and exon 2, precluding normal expression of ARHGAP6. The male proband of family 2 had slightly thinner enamel with greater surface roughness, but exhibited the same pattern of enamel malformations characteristic of males in family 1, which themselves showed minor variations in their enamel phenotypes. We conclude that the enamel defects in both families were caused by amelogenin insufficiency, that deletion of AMELX results in males with a characteristic snow-capped enamel phenotype, and failed ARHGAP6 expression did not appreciably alter the severity of enamel defects when AMELX was absent.

RESUMO

Dentin sialophosphoprotein (DSPP) mutations cause dentin dysplasia type II (DD-II) and dentinogenesis imperfecta types II and III (DGI-II and DGI-III, respectively). We identified two kindreds with DGI-II who exhibited vertical bands of hypoplastic enamel. Both families had a previously reported DSPP mutation that segregated with the disease phenotype. Oral photographs and dental radiographs of four affected and one unaffected participant in one family and of the proband in the second family were used to document the dental phenotypes. We aligned the 33 unique allelic DSPP sequences showing variable patterns of insertions and deletions (indels), generated a merged dentin phosphoprotein (DPP) sequence that includes sequences from all DSPP length haplotypes, and mapped the known DSPP mutations in this context. Analyses of the DSPP sequence changes and their probable effects on protein expression, as well as published findings of the dental phenotype in Dspp null mice, support the hypothesis that all DSPP mutations cause pathology through dominant-negative effects. Noting that Dspp is transiently expressed by mouse pre-ameloblasts during formation of the dentino-enamel junction, we hypothesize that DSPP dominant-negative effects potentially cause cellular pathology in pre-ameloblasts that, in turn, causes enamel defects. We conclude that enamel defects can be part of the dental phenotype caused by DSPP mutations, although DSPP is not critical for dental enamel formation.

RESUMO

Matrix metalloproteinase 20 (MMP20) and kallikrein-related peptidase 4 (KLK4) are thought to be necessary to clear proteins from the enamel matrix of developing teeth. We characterized Mmp20 and Klk4 null mice to better understand their roles in matrix degradation and removal. Histological examination showed retained organic matrix in Mmp20, Klk4, and Mmp20/Klk4 double-null mouse enamel matrix, but not in the wild-type. X-gal histostaining of Mmp20 null mice heterozygous for the Klk4 knockout/lacZ knockin showed that Klk4 is expressed normally in the Mmp20 null background. This finding was corroborated by zymogram and western blotting, which discovered a 40-kDa protease induced in the maturation stage of Mmp20 null mice. Proteins were extracted from secretory-stage or maturation-stage maxillary first molars from wild-type, Mmp20 null, Klk4 null, and Mmp20/Klk4 double-null mice and were analyzed by SDS-PAGE and western blotting. Only intact amelogenins and ameloblastin were observed in secretory-stage enamel of Mmp20 null mice, whereas the secretory-stage matrix from Klk4 null mice was identical to the matrix from wild-type mice. More residual matrix was observed in the double-null mice compared with either of the single-null mice. These results support the importance of MMP20 during the secretory stage and of KLK4 during the maturation stage and show there is only limited functional redundancy for these enzymes.

RESUMO

Previously, mutational analyses identified six disease-causing mutations in 24 amelogenesis imperfecta (AI) kindreds. We have since expanded the number of AI kindreds to 39, and performed mutation analyses covering the coding exons and adjoining intron sequences for the six proven AI candidate genes [amelogenin (AMELX), enamelin (ENAM), family with sequence similarity 83, member H (FAM83H), WD repeat containing domain 72 (WDR72), enamelysin (MMP20), and kallikrein-related peptidase 4 (KLK4)] and for ameloblastin (AMBN) (a suspected candidate gene). All four of the X-linked AI families (100%) had disease-causing mutations in AMELX, suggesting that AMELX is the only gene involved in the aetiology of X-linked AI. Eighteen families showed an autosomal-dominant pattern of inheritance. Disease-causing mutations were identified in 12 (67%): eight in FAM83H, and four in ENAM. No FAM83H coding-region or splice-junction mutations were identified in three probands with autosomal-dominant hypocalcification AI (ADHCAI), suggesting that a second gene may contribute to the aetiology of ADHCAI. Six families showed an autosomal-recessive pattern of inheritance, and disease-causing mutations were identified in three (50%): two in MMP20, and one in WDR72. No disease-causing mutations were found in 11 families with only one affected member. We conclude that mutation analyses of the current candidate genes for AI have about a 50% chance of identifying the disease-causing mutation in a given kindred.
