RESUMEN

OBJECTIVES: Knowledge gaps exist regarding the effects of experiencing child protective services (CPS) out-of-home care (e.g. foster homes) among women with HIV. We examined whether CPS out-of-home care was associated with HIV clinical outcome trajectories among women with HIV in a longitudinal cohort study in Ontario, British Columbia, and Quebec, Canada. METHODS: At three timepoints across 5 years (2013-2018), we examined self-reported current antiretroviral therapy (ART) use and viral load (VL) detectability (>50 copies/mL). We used latent class growth analysis (LCGA) to identify trajectories of ART use and VL outcomes across study waves. LCGA identifies subgroups (classes) with similar trajectories within the sample. We assessed whether HIV outcome trajectories could be predicted by CPS history. We then conducted a mediation analysis to test whether a mental health latent construct mediated the association between CPS history and detectable VL. RESULTS: Nearly one-fifth (n = 272; 19%) of participants (n = 1422; mean age 42.8 years) reported CPS out-of-home care. Most participants (89%) were in classes that consistently used ART and had an undetectable VL. Individuals with CPS out-of-home care histories were twice as likely to have a consistently detectable VL (ß = 0.72, p = 0.02); there were no differences in ART use trajectories. In mediation analyses, we found an indirect path from CPS history to a consistently detectable VL via baseline mental health status (ß = 0.02, 95% confidence interval 0.005-0.04, p = 0.02), with a significant odds ratio (1.12, z = 2.43, p = 0.02). CONCLUSION: Among women with HIV in Canada, experiencing childhood CPS out-of-home care was associated with a reduced likelihood of achieving viral suppression, via poorer mental health.

RESUMEN

The phylogeny of many groups of Orthoptera remains poorly understood. Previous phylogenetic studies largely restricted to few mitochondrial markers found many species in the grasshopper subfamily Gomphocerinae to be para- or polyphyletic, presumably because of incomplete lineage sorting and ongoing hybridization between putatively young lineages. Resolving the phylogeny of the Chorthippus biguttulus species complex is important because many morphologically cryptic species occupy overlapping ranges across Eurasia and serve important ecological functions. We investigated whether multispecies coalescent analysis of 540 genes generated by transcriptome sequencing could resolve the phylogeny of the C. biguttulus complex and related Gomphocerinae species. Our divergence time estimates confirm that Gomphocerinae is a very young radiation, with an age estimated at 1.38 (2.35-0.77) mya for the C. biguttulus complex. Our estimated topology based on complete mitogenomes recovered some species as para- or polyphyletic. In contrast, the multispecies coalescent based on nuclear genes retrieved all species as monophyletic clusters, corroborating most taxonomic hypotheses. Our results underline the importance of using nuclear multispecies coalescent methods for studying young radiations and highlight the need of further taxonomic revision in Gomphocerinae grasshoppers.

RESUMEN

OBJECTIVE: To describe the modification and validation of an existing instrument, the Environment and Policy Assessment and Observation (EPAO), to better capture provider feeding practices. DESIGN: Modifications to the EPAO were made, validity assessed through expert review, pilot tested and then used to collect follow-up data during a two-day home visit from an ongoing cluster-randomized trial. Exploratory factor analysis investigated the underlying factor structure of the feeding practices. To test predictive validity of the factors, multilevel mixed models examined associations between factors and child's diet quality as captured by the Healthy Eating Index-2010 (HEI-2010) score (measured via the Dietary Observation in Childcare Protocol). SETTING: Family childcare homes (FCCH) in Rhode Island and North Carolina, USA.ParticipantsThe modified EPAO was pilot tested with fifty-three FCCH and then used to collect data in 133 FCCH. RESULTS: The final three-factor solution ('coercive control and indulgent feeding practices', 'autonomy support practices', 'negative role modelling') captured 43 % of total variance. In multilevel mixed models adjusted for covariates, 'autonomy support practices' was positively associated with children's diet quality. A 1-unit increase in the use of 'autonomy support practices' was associated with a 9·4-unit increase in child HEI-2010 score (P=0·001). CONCLUSIONS: Similar to the parenting literature, constructs which describe coercive controlling practices and those which describe autonomy-supportive practices emerged. Given that diets of pre-schoolers in the USA remain suboptimal, teaching childcare providers about supportive feeding practices may help improve children's diet quality.

RESUMEN

Background: Children with medical complexity (CMC) are high utilizers of health care services. Telehealth encounters may provide a means to improve care outcomes for this population. Objective: To evaluate the feasibility, usability, and impact of an in-home telehealth device in the care of CMC. Methods: This single-center feasibility study employed a nonblinded randomized clinical trial design. English-speaking caregivers of children within a pediatric complex care program with home Wi-Fi were eligible for participation. Participants were randomized 1.5:1 with stratification based on tracheostomy status to a control group that received usual care or an intervention group that received a telehealth device for in-home use. Patients were followed up for 4 months. The primary outcome was successful device connectivity and data transmission. Data included clinician encounter device usability; caregiver satisfaction; and encounter type, purpose, and cost. Descriptive statistics, negative binomial regression, and Kaplan-Meier plot were used for analysis. Results: Twenty-four patients were enrolled (9 controls, 15 in the intervention group) in September 2016. The telehealth device was attempted in 73 encounters. Device connectivity was successful 96% of the time. Image and sound quality were acceptable in 98% of visits. Caregivers expressed their overall satisfaction with the device. The hospitalization rate was lower in the intervention group (0.77 vs. 1.14 intensive care unit days/patient-months), resulting in $9,425/USD per patient savings compared with the control group. Conclusion: Despite small sample size and short observation period, this study demonstrated that use of an in-home telehealth device is feasible, well received by caregivers, and can result in decreased hospitalizations when compared with usual care.

RESUMEN

BACKGROUND: Although sexual activity and function decline in older women living with HIV, positive dimensions of sexual health, such as satisfaction, are relatively unexplored. We evaluated the prevalence of sexual satisfaction for midlife women with HIV and assessed its relation to women's physical, mental, and sociostructural experiences. SETTING: We studied women in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) over 3 survey waves (2013-2018). METHODS: We included women living with HIV aged ≥45 years who reported ever having consensual sex. Sexual satisfaction was assessed using an item from the Sexual Satisfaction Scale for Women and was dichotomized into satisfactory ("completely/very/reasonably satisfactory") and not satisfactory ("not very/not at all satisfactory"). Probable depression was based on CES-D ≥10. Multivariable logistic regression and fixed effects models determined correlates of sexual satisfaction. Reasons for sexual inactivity and alternate forms of sexual expression were also explored. RESULTS: Among 508 midlife women, 61% were satisfied with their sexual lives at baseline. Women with probable depression had lower odds of sexual satisfaction than those without (aOR: 0.44; 95% CI: 0.27 to 0.71) and worsening depressive symptoms over time were associated with poorer sexual satisfaction ( P = 0.001). Increased sexual activity was associated with higher sexual satisfaction (aOR: 2.75; 95% CI: 1.54 to 4.91); however, 51% of women reporting sexual satisfaction were sexually inactive. Sexually inactive women engaged in alternate forms of sexual expression such as self-pleasure (37%) and intimate relationships without sex (13%). CONCLUSION: Midlife women with HIV have high rates of sexual satisfaction, even in the absence of sexual activity. Depressive symptoms were closely associated with sexual dissatisfaction, alerting providers to the importance of screening for depression and sexual health together.

RESUMEN

Blind snakes (Typhlopidae) are an enigmatic group of small burrowing snakes whose anatomy, phylogenetics, and biodiversity remain poorly known. Madatyphlops comorensis (Boulenger, 1889), endemic to the Comoros Archipelago in the Western Indian Ocean, is one of many species whose phylogenetic placement and generic assignment is unclear. We used DNA barcoding, external morphological examination, and osteological data from 3D reconstruction with micro-CT to study specimens of Madatyphlops from the Comoros Archipelago. Our results support the placement of M. comorensis in Madatyphlops and the recognition of the specimens from Mayotte Island as a closely related but distinct species, which we describe as Madatyphlops eudelini sp. nov. In this context, we present the first detailed osteological descriptions of any species of Madatyphlops, which we hope will serve as groundwork for further osteological studies in this genus and contribute to our limited but growing understanding of the osteology of typhlopid snakes.

RESUMEN

Although endoscopic biopsy of a rectal submucosal nodule may be nondiagnostic, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can be an important tool to make diagnosis. We report a case of a female patient who had an EUS-FNA of a submucosal nodule after a nondiagnostic rectal biopsy. The original diagnosis was erroneously rendered as concerning for necrotic neoplasm. The correct diagnosis of Solesta-induced foreign body reaction was made on reviewing the slides once the history of remote Solesta injection was made available. This case illustrates the pathognomonic features of Solesta-induced rectal nodule and underscores the importance of detailed history as well as inclusion of iatrogenic diseases in the differential to prevent erroneous diagnosis and management. Potential pitfalls in cytopathological diagnosis are discussed.

RESUMEN

Telemedicine, or the use of electronic communication technology to improve patient health, is becoming more widely adopted as a means of bringing together patients, providers and family members to facilitate evaluation, monitoring, diagnosis and treatment. A particularly vulnerable group consists of children with dependence on technology, such as chronic mechanical ventilation. This chapter will provide an overview of how telehealth technology is currently being used, for supporting this patient population through 1) inpatient support 2) integration with the medical home 3) bridging care transitions 4) remote patient management and 5) multispecialty consultations. We will also discuss the impact on quality and cost, the current research environment and practical points for implementation into clinical practice.

RESUMEN

The thrombotic microangiopathies include both hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). Although debate exists as to whether these are separate entities or a spectrum of disease, both result in the clinical picture of thrombocytopenia, hemolytic anemia, and varying degrees of renal and neurologic involvement. Etiology of HUS includes diarrheal infection due to Shiga toxin-producing bacteria, complement deficiency, pneumococcal infection, and cobalamin deficiency. In disease ascribed to TTP, the main etiologic factor is deficiency of an enzyme known as a disintegrin-like and metalloprotease with thrombospondin type 1 repeats, number 13 (ADAMTS-13). The clinical manifestations may vary, but neurologic involvement can be significant, with reports of hypertensive encephalopathy, seizures, thrombosis and infarct. In nondiarrheal forms of disease, recurrence may occur and clinical diagnosis is essential in order to provide a targeted therapy for the suspected etiology. Therapies include supportive care, cobalamin supplementation, as well as plasma infusion and exchange. End stage renal disease may result and transplantation is curative for some forms of the disease. More recent research focuses on targeted immunotherapy to prevent autoantibody prevention. As of yet, there is no one cure for these potentially devastating diseases, and diagnosis and treatment selection presents a challenge to the clinician.
