RESUMO

BACKGROUND: UK cardiovascular disease (CVD) incidence and mortality have declined in recent decades but socioeconomic inequalities persist. AIM: To present a new CVD model, and project health outcomes and the impact of guideline-recommended statin treatment across quintiles of socioeconomic deprivation in the UK. DESIGN AND SETTING: A lifetime microsimulation model was developed using 117 896 participants in 16 statin trials, 501 854 UK Biobank (UKB) participants, and quality-of-life data from national health surveys. METHOD: A CVD microsimulation model was developed using risk equations for myocardial infarction, stroke, coronary revascularisation, cancer, and vascular and non-vascular death, estimated using trial data. The authors calibrated and further developed this model in the UKB cohort, including further characteristics and a diabetes risk equation, and validated the model in UKB and Whitehall II cohorts. The model was used to predict CVD incidence, life expectancy, quality-adjusted life years (QALYs), and the impact of UK guideline-recommended statin treatment across socioeconomic deprivation quintiles. RESULTS: Age, sex, socioeconomic deprivation, smoking, hypertension, diabetes, and cardiovascular events were key CVD risk determinants. Model-predicted event rates corresponded well to observed rates across participant categories. The model projected strong gradients in remaining life expectancy, with 4-5-year (5-8 QALYs) gaps between the least and most socioeconomically deprived quintiles. Guideline-recommended statin treatment was projected to increase QALYs, with larger gains in quintiles of higher deprivation. CONCLUSION: The study demonstrated the potential of guideline-recommended statin treatment to reduce socioeconomic inequalities. This CVD model is a novel resource for individualised long-term projections of health outcomes of CVD treatments.

RESUMO

INTRODUCTION: Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and ciclosporin is standard of care for patients with severe aplastic anaemia (sAA) not eligible or suitable for allogeneic stem cell transplant. While patients respond to IST, few achieve complete responses and a significant proportion are refractory or relapse. The addition of eltrombopag, a thrombopoietin-receptor agonist (TPO-A), to IST has been shown to improve haematological responses in sAA. Avatrombopag is a second-generation TPO-A with potential advantages over eltrombopag. However, to date avatrombopag has not been studied in sAA. METHODS AND ANALYSIS: Investigator-initiated, single-arm registry-based Bayesian Optimal Phase II trial of avatrombopag conducted in two cohorts, patients with untreated sAA (FIRST cohort) and in patients with sAA that has relapsed or is refractory to IST (NEXT cohort). In the FIRST cohort, participants receive IST (equine ATG and ciclosporin) plus avatrombopag from day 1 until day 180 at 60 mg oral daily, with dose adjusted according to platelet count. Participants in the NEXT cohort receive avatrombopag at 60 mg oral daily from day 1 until day 180, with or without additional IST at the discretion of the treating clinician.For each cohort, two primary endpoints (haematological response and acquired clonal evolution) are jointly monitored and the trial reviewed at each interim analysis where a 'go/no-go' decision is made by evaluating the posterior probability of the events of interests. ETHICS AND DISSEMINATION: The trial has received ethics approval (Monash Health RES-18-0000707A). The trial conduct will comply with ICH-GCP and all applicable regulatory requirements. The results of the trial will be submitted to a peer-review journal for publication. TRIAL REGISTRATION NUMBER: ACTRN12619001042134, ACTRN12619001043123.

RESUMO

INTRODUCTION: Efforts to improve health outcomes among adolescents and young adults living with HIV (ALHs) are hampered by limited adolescent engagement in HIV-related research. We sought to understand the views of adolescents, caregivers and healthcare workers (HCWs) about who should make decisions regarding ALHs' research participation. METHODS: We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) with ALHs (aged 14-24 years), caregivers of ALHs and HCWs from six HIV care clinics in Western Kenya. We used semi-structured guides to explore ALHs' involvement in research decisions. Transcripts were analysed using thematic analysis; perspectives were triangulated between groups. RESULTS: We conducted 24 FGDs and 44 IDIs: 12 FGDs with ALHs, 12 with caregivers, and 44 IDIs with HCWs, involving 216 participants. HCWs often suggested that HIV research decision-making should involve caregivers and ALHs deciding together. In contrast, ALHs and parents generally thought decisions should be made individually, whether by HCWs/research teams (although this is likely ethically problematic), adolescents or caregivers. Caregiver and ALH preferences depended on ALHs' age, with younger ALHs requiring more support. A few caregivers felt that ALHs should consult with the research team/HCWs due to their greater knowledge of clinical care. ALHs emphasised that they should independently decide because they thought they had the right to do so and the capacity to consent. Poor communication and parental non-disclosure of HIV status influenced ALHs' views to exclude caregivers from decision-making. Regarding influences on research decision-making, ALHs were more willing to participate based on perceived contribution to science and less interested in participating in studies with potential risks, including loss of confidentiality. DISCUSSION: While research teams and HCWs felt that adolescents and caregivers should jointly make research decisions, ALHs and caregivers generally felt individuals should make decisions. As ALHs sometimes find caregiver support lacking, improving family dynamics might enhance research engagement.

RESUMO

Parent questionnaires pertaining to executive and emotional/behavioral functioning are routinely included in neuropsychological evaluations to complement face-to-face cognitive tests. We evaluated in a clinical sample of 198 6-16 year-old children the degree of overlap and divergence between two common parent rating scales: the Behavior Assessment System for Children-Third Edition (BASC-3) and the Behavior Rating Inventory of Executive Function-Second Edition (BRIEF-2). This sample was 66% male, 70% white, and included both neurological diagnoses (e.g., 33% traumatic brain injury, 12% cerebral palsy) and neurodevelopmental ones (e.g., 10% attention-deficit/hyperactivity disorder). Inter-correlations between composite indices from the respective instruments were moderate (.41-.77). They disagreed about the presence or absence of impairment in 26% of the cases. Cluster analysis revealed four subtypes: Cluster 1 had mild externalizing and executive concerns, Cluster 2 had global emotional/behavioral and executive concerns, Cluster 3 had normal functioning, and Cluster 4 had mild internalizing and executive concerns. Clusters 2 and 3 differed in age and parental education, whereas Clusters 1 and 4 differed in Full Scale IQ. We conclude that BASC-3 and BRIEF-2 provide complementary information about a child's functioning that can inform treatment of neurobehavioral dysfunction. Elevations as well as patterns of the respective profiles on these instruments may help direct such treatment (e.g., cognitive rehabilitation, behavioral management and/or psychotherapy).

RESUMO

INTRODUCTION: Loss to follow-up (LTFU) among adolescents and young adults living with HIV (AYALWH) is a barrier to optimal health and HIV services. We developed and validated a clinical prediction tool to identify AYALWH at risk of LTFU. METHODS: We used electronic medical records (EMR) of AYALWH ages 10 to 24 in HIV care at 6 facilities in Kenya and surveys from a subset of participants. Early LTFU was defined as >30 days late for a scheduled visit in the last 6 months, which accounts for clients with multi-month refills. We developed a tool combining surveys with EMR ('survey-plus-EMR tool'), and an 'EMR-alone' tool to predict high, medium, and low risk of LTFU. The survey-plus-EMR tool included candidate sociodemographics, partnership status, mental health, peer support, any unmet clinic needs, WHO stage, and time in care variables for tool development, while the EMR-alone included clinical and time in care variables only. Tools were developed in a 50% random sample of the data and internally validated using 10-fold cross-validation of the full sample. Tool performance was evaluated using Hazard Ratios (HR), 95% Confidence Intervals (CI), and area under the curve (AUC) ≥ 0.7 for good performance and ≥0.60 for modest performance. RESULTS: Data from 865 AYALWH were included in the survey-plus-EMR tool and early LTFU was (19.2%, 166/865). The survey-plus-EMR tool ranged from 0 to 4, including PHQ-9 ≥5, lack of peer support group attendance, and any unmet clinical need. High (3 or 4) and medium (2) prediction scores were associated with greater risk of LTFU (high, 29.0%, HR 2.16, 95%CI: 1.25-3.73; medium, 21.4%, HR 1.52, 95%CI: 0.93-2.49, global p-value = 0.02) in the validation dataset. The 10-fold cross validation AUC was 0.66 (95%CI: 0.63-0.72). Data from 2,696 AYALWH were included in the EMR-alone tool and early LTFU was 28.6% (770/2,696). In the validation dataset, high (score = 2, LTFU = 38.5%, HR 2.40, 95%CI: 1.17-4.96) and medium scores (1, 29.6%, HR 1.65, 95%CI: 1.00-2.72) predicted significantly higher LTFU than low-risk scores (0, 22.0%, global p-value = 0.03). Ten-fold cross-validation AUC was 0.61 (95%CI: 0.59-0.64). CONCLUSIONS: Clinical prediction of LTFU was modest using the surveys-plus-EMR tool and the EMR-alone tool, suggesting limited use in routine care. However, findings may inform future prediction tools and intervention targets to reduce LTFU among AYALWH.

RESUMO

Jansen-de Vries syndrome (JdVS) is a neurodevelopmental condition attributed to pathogenic variants in Exons 5 and 6 of PPM1D. As the full phenotypic spectrum and natural history remain to be defined, we describe a large cohort of children and adults with JdVS. This is a retrospective cohort study of 37 individuals from 34 families with disease-causing variants in PPM1D leading to JdVS. Clinical data were provided by treating physicians and/or families. Of the 37 individuals, 27 were male and 10 female, with median age 8.75 years (range 8 months to 62 years). Four families document autosomal dominant transmission, and 32/34 probands were diagnosed via exome sequencing. The facial gestalt, including a broad forehead and broad mouth with a thin and tented upper lip, was most recognizable between 18 and 48 months of age. Common manifestations included global developmental delay (35/36, 97%), hypotonia (25/34, 74%), short stature (14/33, 42%), constipation (22/31, 71%), and cyclic vomiting (6/35, 17%). Distinctive personality traits include a hypersocial affect (21/31, 68%) and moderate-to-severe anxiety (18/28, 64%). In conclusion, JdVS is a clinically recognizable neurodevelopmental syndrome with a characteristic personality and distinctive facial features. The association of pathogenic variants in PPM1D with cyclic vomiting bears not only medical attention but also further pathogenic and mechanistic evaluation.

RESUMO

Oesophageal adenocarcinoma is a poor prognosis cancer and the molecular features underpinning response to treatment remain unclear. We investigate whole genome, transcriptomic and methylation data from 115 oesophageal adenocarcinoma patients mostly from the DOCTOR phase II clinical trial (Australian New Zealand Clinical Trials Registry-ACTRN12609000665235), with exploratory analysis pre-specified in the study protocol of the trial. We report genomic features associated with poorer overall survival, such as the APOBEC mutational and RS3-like rearrangement signatures. We also show that positron emission tomography non-responders have more sub-clonal genomic copy number alterations. Transcriptomic analysis categorises patients into four immune clusters correlated with survival. The immune suppressed cluster is associated with worse survival, enriched with myeloid-derived cells, and an epithelial-mesenchymal transition signature. The immune hot cluster is associated with better survival, enriched with lymphocytes, myeloid-derived cells, and an immune signature including CCL5, CD8A, and NKG7. The immune clusters highlight patients who may respond to immunotherapy and thus may guide future clinical trials.

RESUMO

Traditionally, the field of genetics has used patient-reported genetic ancestry to assist in risk assessment, calculate detection rates, and understand residual risks for recessive or X-linked genetic diseases. Patient-reported genetic ancestry is useful for variant curation, based on practice guidelines from medical societies. Words used to describe a person's race, ethnicity, and genetic ancestry have changed over the last few centuries, especially in the last few decades. The origin and use of Caucasian to describe people of European ancestry have come into question. With recommendations from the Department of Health and Human Services (HHS) and the American College of Medical Genetics and Genomics (ACMG), among other organizations, the medical and genetics communities are moving away from using this term altogether. The purpose of this article is to review the history of the word Caucasian and to provide evidence that it should be avoided when documenting genetic ancestry in medical records, laboratory forms, and medical research.

RESUMO

Orofacial cleft (OC) is a common congenital anomaly in humans, which has lifelong implications for affected individuals. This disorder can be classified as syndromic or non-syndromic depending on the presence or absence of additional physical or neurodevelopmental abnormalities, respectively. Non-syndromic cleft is often non-familial in nature and has a complex aetiology, whereas syndromic forms tend to be monogenic. Although individual OC-related syndromes have been frequently described in the medical literature, there has not been a comprehensive review across syndromes, thereby leaving a gap in our knowledge, which this paper aims to address. Six hundred and three patients with cleft-related human phenotype ontology terms were identified within the Deciphering Developmental Disorders study. Genes carrying pathogenic/likely pathogenic variants were identified and reviewed enabling a diagnostic yield of 36.5%. In total, 124 candidate genes for syndromic OC were identified, including 34 new genes that should be considered for inclusion in clinical clefting panels. Functional enrichment and gene expression analyses identified three key processes that were significantly overrepresented in syndromic OC gene lists: embryonic morphogenesis, protein stability and chromatin organization. Comparison with non-syndromic OC gene networks led us to propose that chromatin remodelling specifically contributes to the aetiology of syndromic OC. Disease-driven gene discovery is a valid approach to gene identification and curation of gene panels. Through this approach, we have started to unravel common molecular pathways contributing to syndromic orofacial clefting.

RESUMO

Youth living with HIV (YLHIV) report that negative interactions with health care workers (HCWs) affects willingness to return to care. This stepped wedge randomized trial evaluated effectiveness of a standardized patient actor (SP) HCW training intervention on adolescent engagement in care in Kenya. HCWs caring for YLHIV at 24 clinics received training on adolescent care, values clarification, communication, and motivational interviewing, with 7 SP encounters followed by facilitated feedback of videotaped interactions. Facilities were randomized to timing of the intervention. The primary outcome was defined as return within 3 months after first visit (engagement) among YLHIV who were either newly enrolled or who returned to care after >3 months out of care. Visit data was abstracted from electronic medical records. Generalized linear mixed models adjusted for time, being newly enrolled, and clustering by facility. YLHIV were surveyed regarding satisfaction with care. Overall, 139 HCWs were trained, and medical records were abstracted for 4,595 YLHIV. Median YLHIV age was 21 (IQR 19-23); 82% were female, 77% were newly enrolled in care, and 75% returned within 3 months. Half (54%) of trained HCWs remained at their clinics 9 months post-training. YLHIV engagement improved over time (global Wald test, p = 0.10). In adjusted models, the intervention showed no significant effect on engagement [adjusted Prevalence Ratio (aPR) = 0.95, 95% Confidence Interval (CI): 0.88-1.02]. Newly enrolled YLHIV had significantly higher engagement than those with prior lapses in care (aPR = 1.18, 95%CI: 1.05-1.33). Continuous satisfaction with care scores were significantly higher by wave 3 compared to baseline (coefficient = 0.38, 95%CI: 0.19-0.58). Despite provider skill improvement, there was no effect of SP training on YLHIV engagement in care. This may be due to temporal improvements or turnover of trained HCWs. Strategies to retain SP-training benefits need to address HCW turnover. YLHIV with prior gaps in care may need more intensive support.

RESUMO

A de novo novel variant of uncertain significance p. (Arg532del) in the KLHL15 gene was identified by trio exome analysis in a child with global developmental delay, coarse facial features, repetitive behaviour, increased fatigability, poor feeding and gastro-oesophageal reflux. Comparative modelling and structural analysis were performed to gain insight into the effects of the variant on KLHL15 protein structure and function, with a view to aiding variant classification. The p. (Arg532del) variant affects a highly conserved residue within one of the Kelch repeats of the KLHL15 protein. This residue contributes to the stability of loop regions at the substrate binding surface of the protein; comparative modelling of the variant protein predicts altered topology at this surface, including at residue Tyr552, which is known to be important for substrate binding. We propose that it is highly probable that the p. (Arg532del) variant has a deleterious impact on KLHL15 structure, leading to a reduced level of protein function in vivo.

RESUMO

INTRODUCTION: Engaging adolescents in HIV care and research promotes the development of interventions tailored to their unique needs. Guidelines generally require parental permission for adolescents to receive HIV care/testing or participate in research, with exceptions. Nevertheless, parental permission requirements can restrict adolescent involvement in care and research. To better appreciate prospects for policy reform, we sought to understand the perspectives of stakeholders involved in the development, review and implementation of policies related to adolescents living with HIV. METHODS: Semi-structured individual interviews (IDIs) were conducted from October 2019 to March 2020 with 18 stakeholders with expertise in the (1) development of policy through membership in the Law Society of Kenya or work as a health policy official; (2) review of policy through ethics review committee service; or (3) implementation of policy through involvement in adolescent education. IDIs were conducted in English by Kenyan social scientists, audio-recorded and transcribed verbatim. We used thematic analysis to identify themes around how policies can be reformed to improve adolescent engagement in HIV care and research. RESULTS: Our analysis identified three major themes. First, policies should be flexible rather than setting an age of consent. Stakeholders noted that adolescents' capacity for engagement in HIV care and research depended on context, perceived risks and benefits, and "maturity"-and that age was a poor proxy for the ability to understand. Second, policies should evolve with changing societal views about adolescent autonomy. Participants recognized a generational shift in how adolescents learn and mature, suggesting the need for a more frequent review of HIV care and research guidelines. Third, adults should empower adolescent decision-making. Stakeholders felt that caregivers can gradually involve adolescents in decision-making to equip them to gain ownership over their health and lives, improving their confidence and capacity. CONCLUSIONS: Revising relevant laws to consider context, alternative measures of maturity, and evolving societal views about adolescence, along with supporting caregivers to assist in developing adolescent autonomy may promote more equitable and representative participation of adolescents in HIV care and research. Additional research should explore how to support caregivers and other adults to empower adolescents and improve stakeholder engagement in a more routine process of policy reform.

RESUMO

HIV self-testing (HIVST) can improve testing completion among adolescents and young adults (AYA), although its influence on sexual behaviors is unclear. We evaluated whether HIVST was associated with changes in talking with sexual partners about HIVST, condom use, and HIV risk perception among AYA ages 15-24 years in a study of HIVST distribution through homes, pharmacies, and nightclubs in Nairobi, Kenya. All participants had negative HIVST results. Regression models were used to evaluate changes between pre-HIVST and 4 months post-HIVST. Overall, there was a significant increase in talking with sexual partners about HIVST. There was a significant reduction in number of condomless sex acts among AYA recruited through pharmacies and homes. Unexpectedly, among females, there was a significant decrease in consistent condom use with casual partners. HIVST services for AYA may benefit from including strategies to support condom use and partner communication about self-testing adapted to specific populations and partnerships.

RESUMO

OBJECTIVE: The aim of this study was to compare patient-reported urinary, bowel, and sexual functioning of ALaCaRT Trial participants randomized to open or laparoscopic surgery for rectal cancer. SUMMARY BACKGROUND DATA: The primary endpoint, noninferiority of laparoscopic surgical resection adequacy, was not established. METHODS: Participants completed QLQ-CR29 at baseline, 3, and 12 months post-surgery. Additionally, women completed Rosen's Female Sexual Functioning Index (FSFI). Men completed the International Index of Erectile Function (IIEF) and QLQ-PR25. We compared the proportions of participants in each group who experienced moderate/severe symptoms/dysfunction at each time-point and compared mean difference scores from baseline to 12 months between groups. All analyses were intention-to-treat. Sexual functioning analyses included only the participants who expressed sexual interest at baseline. RESULTS: Baseline PRO compliance of 475 randomized participants was 88%. At 12 months, a lower proportion of open surgery participants experienced moderate-severe fecal incontinence and sore skin, compared to Laparoscopic participants, and a lower proportion of men randomized to open surgery experienced moderate-severe urinary symptoms. There were no differences at 3 months for bowel or urinary symptoms. Sexual functioning among sexually interested participants was similar between groups at 3 and 12 months; however, a lower proportion of women reported moderate to severe sexual dissatisfaction at 3 months in the open as compared to the laparoscopic group, (Rebecca.mercieca@sydney.edu.au., 95% CI 0.03-0.39). DISCUSSION: Despite the slightly lower proportions of open surgery participants self-reporting moderate-severe symptoms for 3 of 16 urinary/bowel domains, and lack of differences in sexual domains, it remains difficult to recommend one surgical approach over another for rectal resection.

RESUMO

Community-based delivery of oral HIV self-testing (HIVST) may expand access to testing among adolescents and young adults (AYA). Eliciting youth perspectives can help to optimize these services. We conducted nine focus group discussions (FGDs) with HIV negative AYA aged 15-24 who had completed oral HIVST following community-based distribution through homes, pharmacies, and bars. FGDs were stratified by distribution point and age (15-17, 18-24). Participants valued HIVST because it promoted greater autonomy and convenience compared to traditional clinic-based testing. AYA noted how HIVST could encourage positive behavior change, including using condoms to remain HIV negative. Participants recommended that future testing strategies include individualized, ongoing support during and after testing. Support examples included access to trained peer educators, multiple community-based distribution points, and post-test support via phones and websites. Multiple distribution points and trained peer educators' involvement in all steps of distribution, testing, and follow-up can enhance future community-based HIVST programs.

RESUMO

Newborn congenital cytomegalovirus (cCMV) screening programs have been found to increase the rates of early diagnosis and treatment. In North America, newborn cCMV screening programs have not been widely implemented, leaving healthcare providers to rely on clinical suspicion alone to prompt testing. This study sought to examine healthcare providers' cCMV testing practices at a quaternary children's hospital. A retrospective review of the electronic health record was completed for eligible infants over a six-year period. Bivariate calculations and analyses were performed. Between 2014 and 2019, a total of 40,091 infants were cared for at the study institution, of which 178 were tested for cCMV and 10 infants were diagnosed with cCMV. Isolated small-for-gestational age was the most common indication (53/178) to prompt testing. Overall, the cCMV testing rate was 4.5 tests per 1000 infants, with a resulting diagnostic prevalence of 0.2 cases per 1000 infants, which is 15-fold lower than the expected prevalence. Providers relying on clinical suspicion alone are infrequently testing infants for cCMV, resulting in missed diagnoses and missed opportunities for treatment. Systematic cCMV screening practices may improve diagnosis, treatment, and childhood outcomes.

RESUMO

School-related factors may influence retention in care and adherence to antiretroviral therapy (ART) among adolescents with human immunodeficiency virus (HIV). We analyzed data from in-depth interviews with 40 adolescents with HIV (aged 14 -19 years), 40 caregivers of adolescents with HIV, and 4 focus group discussions with healthcare workers to evaluate contextual factors affecting adherence to ART and clinic attendance among adolescents, with a focus on the school environment. Informed by Anderson's Model of Health Services Utilization, transcripts were systematically coded and synthesized to identify school-related themes. All groups identified the school environment as a critical barrier to engagement in HIV care and medication adherence for adolescents with HIV. Adolescent participants reported inflexible school schedules and disclosure to school staff as the biggest challenges adhering to clinic appointments and ART. Adolescents described experiencing stigma and discrimination by peers and school staff and would adjust when, where and how often they took ART to avoid inadvertent disclosure. Boarding school students faced challenges because they had limited private space or time. Caregivers were often instrumental in navigating school permissions, including identifying a treatment supporter among school staff. Additional research engaging school staff may guide interventions for schools to reduce stigma and improve adherence and retention.

RESUMO

BACKGROUND: Angiotensin receptor blockers (ARBs) and ß blockers are widely used in the treatment of Marfan syndrome to try to reduce the rate of progressive aortic root enlargement characteristic of this condition, but their separate and joint effects are uncertain. We aimed to determine these effects in a collaborative individual patient data meta-analysis of randomised trials of these treatments. METHODS: In this meta-analysis, we identified relevant trials of patients with Marfan syndrome by systematically searching MEDLINE, Embase, and CENTRAL from database inception to Nov 2, 2021. Trials were eligible if they involved a randomised comparison of an ARB versus control or an ARB versus ß blocker. We used individual patient data from patients with no prior aortic surgery to estimate the effects of: ARB versus control (placebo or open control); ARB versus ß blocker; and indirectly, ß blocker versus control. The primary endpoint was the annual rate of change of body surface area-adjusted aortic root dimension Z score, measured at the sinuses of Valsalva. FINDINGS: We identified ten potentially eligible trials including 1836 patients from our search, from which seven trials and 1442 patients were eligible for inclusion in our main analyses. Four trials involving 676 eligible participants compared ARB with control. During a median follow-up of 3 years, allocation to ARB approximately halved the annual rate of change in the aortic root Z score (mean annual increase 0·07 [SE 0·02] ARB vs 0·13 [SE 0·02] control; absolute difference -0·07 [95% CI -0·12 to -0·01]; p=0·012). Prespecified secondary subgroup analyses showed that the effects of ARB were particularly large in those with pathogenic variants in fibrillin-1, compared with those without such variants (heterogeneity p=0·0050), and there was no evidence to suggest that the effect of ARB varied with ß-blocker use (heterogeneity p=0·54). Three trials involving 766 eligible participants compared ARBs with ß blockers. During a median follow-up of 3 years, the annual change in the aortic root Z score was similar in the two groups (annual increase -0·08 [SE 0·03] in ARB groups vs -0·11 [SE 0·02] in ß-blocker groups; absolute difference 0·03 [95% CI -0·05 to 0·10]; p=0·48). Thus, indirectly, the difference in the annual change in the aortic root Z score between ß blockers and control was -0·09 (95% CI -0·18 to 0·00; p=0·042). INTERPRETATION: In people with Marfan syndrome and no previous aortic surgery, ARBs reduced the rate of increase of the aortic root Z score by about one half, including among those taking a ß blocker. The effects of ß blockers were similar to those of ARBs. Assuming additivity, combination therapy with both ARBs and ß blockers from the time of diagnosis would provide even greater reductions in the rate of aortic enlargement than either treatment alone, which, if maintained over a number of years, would be expected to lead to a delay in the need for aortic surgery.

RESUMO

ABSTRACT: Pre-exposure prophylaxis (PrEP) uptake and adherence among adolescent girls and young women (AGYW) may be negatively influenced by poor interactions with health care providers. We assessed PrEP counseling using unannounced standardized patient actors (USPs) at routine care clinics in Kenya. Trained actors posed as AGYW seeking PrEP services following case scripts and completed a checklist of provider adherence to national guidelines and communication skills. Scores were converted into a percentage and compared using linear regression. The overall mean quality score was 52.1 and varied across case scripts: a married new initiator yielded higher scores than portrayals of adherence/stigma challenges, transactional sex, and a minor adolescent. Mean guideline scores (31.4) were lower than communication scores (72.8), although in 36.5% of encounters, USPs stated they would not seek help from that provider again. Unannounced standardized patients reported provider reluctance to offer PrEP to AGYW. Interventions to strengthen provider counseling skills are needed.

RESUMO

ABSTRACT: Adolescent participation in research is critical to inform interventions that improve outcomes for this group. Adolescents and young adults living with HIV often present to care without caregivers, yet caregiver permission is typically required for those younger than 18 years. We evaluated whether understanding of key consent information differed between adolescents ( n = 1,393) and caregiver adults ( n = 169). Compared with caregivers, adolescents aged 10-14 years showed significantly lower understanding, whereas understanding for older adults living with HIV did not differ significantly from caregivers. Risks were the least understood consent information for all age groups. Our findings suggest that for low-risk research, waiving caregiver permission requirements will not compromise the ethical need to ensure understanding of research before enrollment and may allow adolescents greater access to potential research benefits.
