RESUMO

To slow the spread of COVID-19 many mental health providers transitioned to telehealth delivery of trauma-focused treatment for maltreated children. However, these providers faced myriad challenges, including equitable access to equipment and technical demands of telehealth software. Training clinics overseeing pre-doctoral clinical psychology interns experienced the added challenge of providing quality supervision and training via telehealth. This study involves a retrospective application of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework to describe the innovative adaptation to a telehealth service delivery model in a training clinic providing evidence-based trauma-focused treatment to children and their families. Mixed methods data from clinic records and intern evaluations indicate that compared to pre-COVID (February 2019 - February 2020), during early COVID (April 2020 - April 2021) more patients accessed clinic services, interns reported fewer hours of individual supervision, and interns reported greater satisfaction with their training experiences. Implications for ongoing provision of telehealth services are discussed.

RESUMO

BACKGROUND: Although children's self-blame appraisals are recognized as important sequelae of child victimization that contribute to subsequent adjustment problems, little is known about the factors that predict their development and longitudinal course. OBJECTIVE: The current study examines the stability and longitudinal predictors of children's self-blame appraisals among a sample of children reported for family violence. PARTICIPANTS AND SETTING: Children (N = 195; 63 % female) aged 7 to 17 years (Mage = 12.17) were recruited as part of a longitudinal assessment of families referred to the United States Navy's Family Advocacy Program due to allegations of child physical abuse, sexual abuse, or intimate partner violence. METHODS: Children completed assessments on self-blame at 3 time points (baseline, 9-12 months, and 18-24 months) and baseline measures of their victimization experience, caregiver-child conflict, and depression. RESULTS: In univariate analyses, victimization that involved injury (r = 0.29, p < .001), the number of perpetrators (r = 0.23, p = .001), the number of victimization types (r = 0.32, p < .001), caregiver-child conflict (r = 0.36, p < .001), and depression (r = 0.39, p < .001) were each positively associated with baseline self-blame. When examined in a single longitudinal multilevel model, results indicated only caregiver-child conflict (b = 0.08, p = .007) and baseline depression (b = 0.06, p = .013) predicted increases in self-blame. CONCLUSION: Findings suggest clinicians and researchers may consider assessment of victimization characteristics, caregiver-child relationships, and depression symptoms to identify children most at risk for developing self-blame appraisals.

RESUMO

Transient blockade of glycine decarboxylase (GLDC) can restrict de novo pyrimidine synthesis, which is a well-described strategy for enhancing the host interferon response to viral infection and a target pathway for some licenced anti-inflammatory therapies. The aminothiol, cysteamine, is produced endogenously during the metabolism of coenzyme A, and is currently being investigated in a clinical trial as an intervention in community acquired pneumonia resulting from viral (influenza and SARS-CoV-2) and bacterial respiratory infection. Cysteamine is known to inhibit both bacterial and the eukaryotic host glycine cleavage systems via competitive inhibition of GLDC at concentrations, lower than those required for direct antimicrobial or antiviral activity. Here, we demonstrate for the first time that therapeutically achievable concentrations of cysteamine can inhibit glycine utilisation by epithelial cells and improve cell-mediated responses to infection with respiratory viruses, including human coronavirus 229E and Influenza A. Cysteamine reduces interleukin-6 (IL-6) and increases the interferon-λ (IFN-λ) response to viral challenge and in response to liposomal polyinosinic:polycytidylic acid (poly I:C) simulant of RNA viral infection.

RESUMO

Vaccine hesitancy is a serious threat to global health; however, significant COVID-19 vaccine hesitancy exists throughout the United States. The 5C model, which postulates five person-level determinants for vaccine hesitancy - confidence, complacency, constraints, risk calculation, and collective responsibility - provides one theoretical way of understanding COVID-19 vaccine hesitancy. The present study examined the effects of these 5C drivers of vaccine behavior on early vaccine adoption and vaccine intentions above and beyond theoretically salient demographic characteristics and compared these associations across a National sample (n = 1634) and a statewide sample from South Carolina (n = 784) - a state with documented low levels of COVID-19 vaccination uptake. This study used quantitative and qualitative data collected in October 2020 to January 2021 from the MFour-Mobile Research Panel, a large, representative non-probability sample of adult smartphone users. Overall, the South Carolina sample reported lower COVID-19 vaccine intentions and higher levels of 5C barriers to vaccine uptake compared to the National sample. Findings further indicated that both demographic characteristics (race) and certain drivers of vaccine behavior (confidence and collective responsibility) are associated with vaccine trust and intentions across samples above and beyond other variables. Qualitative data indicated that COVID-19 vaccine hesitancy was driven by fears about the quick vaccine development, limited research, and potential side effects. Although there are some limitations to the cross-sectional survey data, the present study offers valuable insight into factors associated with early COVID-19 vaccine hesitancy across the United States.

RESUMO

Sustaining the functionality of drinking water supplies in low- and middle-income countries is a longstanding challenge. Growing awareness of this problem has motivated increased attention to validly and reliably measuring water point functionality, including among handpumps, which serve approximately 9 % of the global population. Yet the most widely used indicator of functionality, whether a water point provides water, has limited validity, reliability, and utility. We tested the inter-rater (agreement among measurements taken by different people) and intra-rater (agreement among repeated measurements taken by the same person) reliability of three handpump functionality field tests in Uganda: pump capacity, 10-minute leakage rate, and flowrate. One person equipped with a stopwatch and a 20-liter container can complete the tests for one handpump in 15 min. The same three to four raters each conducted the tests three times on 28 handpumps. Different sets of four to five raters each conducted the tests once on 32 handpumps. Intraclass correlation coefficients were estimated to indicate inter- and intra-rater reliability. Ten-minute leakage rate had the highest inter-rater reliability, followed by pump capacity. Flowrate, which is commonly measured manually as part of handpump functionality assessments, had poor inter-rater reliability. Indicators derived from all three tests had high intra-rater reliability. Drawing on our inter-rater reliability results, we propose a fully quantitative procedure and validate an ordinal scale of physical handpump functionality based on the 10-minute leakage rate and pump capacity tests. This measurement procedure can be usefully incorporated into service delivery monitoring and research to enhance the objectivity, utility, and comparability of global handpump functionality data. Future studies can test the reliability of these indicators in other contexts and their value for predicting handpump breakdown.

RESUMO

Maternal support is theorized as a critical predictor of children's recovery from sexual abuse. However, following disclosure, several factors may cause maternal support to fluctuate over time. This study examined the effects of hypothesized risk factors, mother's relationship to the perpetrator and maternal psychological distress, as well as protective factors, maternal belief of disclosure, lower levels of child blame, and mother-child relationship quality, as predictors of change in maternal support over a 9 month period. Mothers (Mage = 38.42, SD = 8.99) and their children (Mage = 11.57, SD = 2.69; 85% female), recruited from a child advocacy center following sexual abuse disclosure, completed measures of maternal support. Mothers reported on their relationship to the perpetrator, psychological distress, belief of disclosure, child blame, and mother-child relationship quality. On average, mother- and child-reports of maternal support were stable across time. Belief of disclosure and child blame predicted mother- and child-report of maternal support. Psychological distress and mother-child relationship quality predicted change in mother-report, but not child-report of maternal support. Researchers and clinicians should consider potential fluctuations in maternal support in assessment and intervention following child sexual abuse.

RESUMO

BACKGROUND: The Maternal Self-report Support Questionnaire (MSSQ) is among the most rigorously evaluated measures of caregiver support following child sexual abuse, but there is a paucity of data on the factor structure and variance of the MSSQ across diverse groups of caregivers and their children. OBJECTIVE: The present study examined the factor structure and measurement invariance of the MSSQ across 386 non-offending caregivers following a disclosure of child sexual abuse. PARTICIPANTS AND SETTING: Data were collected from non-offending caregivers at two Child Advocacy Centers (n = 277; n = 109) in the United States. METHODS: Caregivers completed the MSSQ and assessments of child age, caregiver-child relationship, and caregiver preferred language. RESULTS: Confirmatory factor analyses replicated the original two-factor structure, with the emotional support and blame/doubt subscales emerging as distinct factors. Multigroup confirmatory factor analyses showed measurement invariance across child age and caregiver-child relationship (mother vs. another caregiver). Evidence of partial invariance was found for caregiver preferred language. Comparisons of scores indicated caregiver support varied by child age and caregiver preferred language. CONCLUSIONS: Overall, findings suggest the MSSQ can be used to measure caregiver support across caregivers with children of different ages and both mothers and non-mothers, but caution should be practiced in interpreting mean-level differences between English- and Spanish-speaking caregivers.

RESUMO

Expanding drinking water chlorination could substantially reduce the burden of disease in low- and middle-income countries, but the taste of chlorinated water often impedes adoption. We developed a Monte Carlo simulation to estimate the effect of people's choice to accept or reject drinking water based on chlorine taste and their subsequent exposure to E. coli and trihalomethanes, a class of disinfection byproduct (DBP). The simulation used empirical data from Dhaka, Bangladesh, a megacity with endemic waterborne disease. We drew on published taste acceptability thresholds from Dhaka residents, measured residual chlorine and thermotolerant E. coli inactivation following the addition of six chlorine doses (0.25-3.0 mg/L as Cl2) to untreated piped water samples from 100 locations, and analyzed trihalomethane formation in 54 samples. A dose of 0.5 mg/L, 75% lower than the 2 mg/L dose typically recommended for household chlorination of low-turbidity waters, minimized overall exposure to E. coli. Doses of 1-2 mg/L maximized overall exposure to trihalomethanes. Accounting for chlorine taste aversion indicates that microbiological exposure increases and DBP exposure decreases above certain doses as a higher proportion of people reject chlorinated water in favor of untreated water. Taken together with findings from other modeling analyses, empirical studies, and field trials, our results suggest that taste acceptability should be a critical consideration in establishing chlorination dosing guidelines. Particularly when chlorination is first implemented in water supplies with low chlorine demand, lower doses than those generally recommended for household water treatment can help avoid taste-related objections while still meaningfully reducing contaminant exposure.

RESUMO

Pseudomonas aeruginosa is a major opportunistic human pathogen which employs a myriad of virulence factors. In people with cystic fibrosis (CF) P. aeruginosa frequently colonises the lungs and becomes a chronic infection that evolves to become less virulent over time, but often adapts to favour persistence in the host with alginate-producing mucoid, slow-growing, and antibiotic resistant phenotypes emerging. Cysteamine is an endogenous aminothiol which has been shown to prevent biofilm formation, reduce phenazine production, and potentiate antibiotic activity against P. aeruginosa, and has been investigated in clinical trials as an adjunct therapy for pulmonary exacerbations of CF. Here we demonstrate (for the first time in a prokaryote) that cysteamine prevents glycine utilisation by P. aeruginosa in common with previously reported activity blocking the glycine cleavage system in human cells. Despite the clear inhibition of glycine metabolism, cysteamine also inhibits hydrogen cyanide (HCN) production by P. aeruginosa, suggesting a direct interference in the regulation of virulence factor synthesis. Cysteamine impaired chemotaxis, lowered pyocyanin, pyoverdine and exopolysaccharide production, and reduced the toxicity of P. aeruginosa secreted factors in a Galleria mellonella infection model. Thus, cysteamine has additional potent anti-virulence properties targeting P. aeruginosa, further supporting its therapeutic potential in CF and other infections.

RESUMO

Delivering safe water in cities of lower- and middle-income countries remains elusive even where there is a piped supply. Passive, in-line chlorination upstream of the point of water collection reduces child diarrhea without the behavior change required for point-of-use water treatment products or manual chlorine dispensers. We conducted a price experiment to measure effective demand (willingness and ability to pay) for an in-line chlorination service using tablet chlorinators among 196 landlords of rental housing properties in Dhaka, Bangladesh. We offered a 12-month subscription using Becker-DeGroot-Marschak auctions with real money payments. The service consistently delivered chlorinated water and satisfied tenants. Landlords' effective demand for in-line chlorination was similar to or greater than that for point-of-use treatment products and manual chlorine dispensers previously documented among Dhaka households. Over the service period, landlords renting to low-income households had lower effective demand than those renting to middle-income households despite similar initial rates of payment across both groups. Making in-line chlorination financially viable for the lowest-income consumers would likely require service cost reductions, subsidies, or both. Our findings suggest that even revealed preference experiments may overestimate the effective demand needed to sustain water supply improvements, especially in low-income populations, if they only measure demand once.

RESUMO

While extensive literature exists on barriers and strategies to increase minority participation in clinical trials, progress is limited. Few strategies were evaluated in randomized trials. We studied the impact of RECRUIT, a trust-based, cluster randomized minority recruitment trial layered on top of four traditional NIH-funded parent trials (BMT CTN, CABANA, PACES, STEADY-PD III; fifty specialty sites). RECRUIT was conducted from July 2013 through April 2017. Intervention sites implemented trust-based approaches customized to individual sites, promoting relationships between physician-investigators and minority-serving physicians and their minority patients. Control sites implemented only parent trials' recruitment procedures. Adjusting for within-site clustering, we detected no overall intervention effect, odds ratio 1.3 (95% confidence limits 0.7,2.4). Heterogeneity among parent trials may have obscured the effect. Of the four parent trials, three enrolled more minorities in intervention versus control sites. CABANA odds ratio = 4.2 (adjusted 95%CL 1.5,11.3). PACES intervention sites enrolled 63% (10/16) minorities; control sites enrolled one participant in total, a minority, yielding an incalculable odds ratio. STEADY-PD III odds ratio = 2.2 (adjusted 95%CL 0.6,8.5). BMT CTN odds ratio < 1, 0.8 (adjusted 95%CL 0.4,1.8). In conclusion, RECRUIT findings suggest the unique trust-based intervention increased minority recruitment to intervention trials in ¾ of studied trials. Physician-investigators' participation was critical to recruitment success. Lack of commitment to minority recruitment remained a barrier for some physician-investigators, especially in control sites. We recommend prospective physician investigators commit to minority recruitment activities prior to selection as site investigators and trial funding include some compensation for minority recruitment efforts.

RESUMO

OBJECTIVES: To assess the reporting quality of randomized controlled trials and experimental animal studies examining urethroplasty in reconstructive urological surgery literature. METHODS: We performed a comprehensive literature search to identify all urethroplasty-related RCTs examining humans as well as animal models. We used the Consolidated Standards of Reporting Trials (CONSORT) and the Animals in Research: Reporting in vivo Experiments (ARRIVE) guidelines to assess reporting quality. Two reviewers performed data abstraction independently and in duplicate. We then generated descriptive statistics including CONSORT (0-25) and ARRIVE (0-20) summary scores using the median and interquartile range. RESULTS: Twenty studies were ultimately included; 14 randomized controlled trials and 6 experimental animal studies. All studies were two-armed, parallel group studies. Median sample sizes (and interquartile range) of the human and animal studies were 48.5 (31.8-53.8) and 18 (15.3-27.5), respectively. The median CONSORT and ARRIVE scores were 10.0 (8.75-12.63) and 7.97 (6.79-8.64), respectively. Human randomized controlled trials did not consistently report the method of allocation concealment (6/14; 42.9%), blinding (2/14; 14.3%), or discuss the generalizability of the results (6/14; 42.9%). Animal studies infrequently reported why a given animal model was used (1/6; 16.7%), how they were allocated to groups (0/6; 0%) or what the experimental primary and secondary outcomes were (0/6; 0%). CONCLUSIONS: Urethroplasty literature is marked by a paucity of both randomized controlled trials and experimental design animal studies. The existing studies are inconsistently reported and are therefore of uncertain methodological quality.

RESUMO

Violence is a public health concern linked with mental health problems among adolescents, and risk behavior increases the likelihood of violence exposure. Family cohesion may attenuate the negative effects of risk behavior. The purpose of this study was to examine family cohesion as a moderator in the relation between risk behavior (substance use and delinquency) and violence exposure, and to explore longitudinal associations among cohesion, violence exposure, and subsequent mental health outcomes (PTSD and depression). Data were drawn from the National Survey of Adolescents-Replication, a nationally representative sample of 3604 adolescents, with data collected via structured phone interviews at three waves spanning a two-year period. Hypotheses were tested using longitudinal structural equation modeling. Findings revealed that high family cohesion attenuated the relation between risk behavior and subsequent violence exposure. Wave 2 violence exposure was associated with more Wave 3 mental health problems, but high family cohesion was related to fewer subsequent symptoms. Follow-up analyses revealed that family cohesion moderated the relation between risk behavior and experiencing, but not witnessing, violence. Several demographic associations were observed. Although risk behavior increases exposure to violence, and in turn, mental health problems, family cohesion may serve as a protective factor, attenuating the link between risk behavior and subsequent negative consequences. This effect emerged even when accounting for demographic and socioeconomic covariates. Interventions with adolescents should target family relationships as a protective factor to reduce risk of violence exposure and mental health problems, particularly for adolescents who are engaging in high-risk behaviors.

RESUMO

INTRODUCTION: High-quality evidence regarding questions of diagnostic accuracy relies on transparent reporting of study results. The quality of reporting for such studies in the urologic literature is unknown. METHODS: In accordance with an a priori protocol, we systematically searched for all articles on diagnostic accuracy studies published in four major urologic journals in 2015. Using the 2015 STAndards for Reporting Diagnostic accuracy studies (STARD) checklist, two of us independently abstracted data. For each article, we calculated STARD summary scores (scale of 0-30, with higher scores reflecting higher-quality reporting). We compared scores by journal, topic, and sample size. RESULTS: We screened 819 references of which 61 met inclusion criteria. Nearly two-thirds of studies (39/61%; 63.9%) addressed prostate cancer diagnosis or staging; less than one in ten (6/61%; 9.8%) was conducted in non-oncological disease settings. The major focus for the investigation of new index tests lay in imaging modalities (33/61%; 54.1%); over half of these imaging studies addressed magnetic resonance imaging (18/61%; 29.5%). The average STARD score was 18.9 ± 2.4 (range 12-24). Six criteria had poor reporting compliance and were met by less than 20% of studies. We found no association between reporting quality and topic, journal or study size. CONCLUSIONS: The reporting quality of studies of diagnostic accuracy appears modest and independent of topic, journal or study size. There is an urgent need for greater awareness for the reporting quality of these studies among readers, editors, and investigators to raise evidentiary standards on issues of diagnosis.

RESUMO

PURPOSE OF REVIEW: To evaluate contemporary rationale and techniques for ectopic reservoir/balloon placement in complex urologic prosthetics patients. RECENT FINDINGS: Recent studies have demonstrated that ectopic reservoir placement is safe and durable when compared to traditional space of Retzius placement. Complex patients exist on a spectrum from those with a previously violated retropubic space, to those with bilaterally obscured external inguinal rings and/or multiple prior prosthetic reservoirs. Ectopic placement has become more commonplace and accepted as a viable alternative strategy over the past 7 years. Concerns relating to reservoir palpability and long-term outcomes have been allayed. The risk of deep pelvic complications appears to be negligible after both placement or removal of ectopic reservoirs when performed by experienced implanters even in the most complex patient. Ectopic placement of prosthetic balloons and reservoirs offers unique advantages and has become commonplace in contemporary prosthetic urology practice.

RESUMO

Social stress, especially dyadic conflict among couples, is an important correlate of addiction. Several authors have suggested that the neuropeptide oxytocin (OT) may be useful in the treatment of couples with substance misuse. However, the literature examining OT among couples is scant and has yielded mixed findings. The current study examined the effects of OT versus placebo on emotional (e.g., warmth and anger) and physiological (e.g., skin conductance and heart rate) reactivity to a conflict resolution task in 30 heterosexual couples (N=60) in which one or both members misused substances. Using a randomized, double-blind, placebo-controlled design, both partners within each dyad were randomized to the same treatment condition. Participants completed a standardized conflict resolution task at baseline and 45 minutes following drug self-administration. Physiological measures were examined continuously during the laboratory tasks and emotional reactivity was self-reported at baseline and at 5 time points over the course of 1 hour following the second conflict resolution task. Results of a multi-level growth curve model accounting for baseline scores, gender and drug condition indicate that positive emotional experiences and skin conductance measures increased over the 5 time points. Neither drug condition nor gender was significantly related to outcomes, and no interaction effects were observed. These findings highlight the complexities involved in translational OT research and suggest that the impact of OT on key outcomes requires further exploration in regards to OT's potential therapeutic benefit.

RESUMO

Staphylococcus aureus is a clinically significant human pathogen that causes infectious diseases ranging from skin and soft tissue infections (SSTI) and health care-associated infections (HAI) to potentially fatal bacteremia and endocarditis. Nasal carriage of S. aureus, especially for persistent carriage, is associated with an increased risk of subsequent infection, particularly nosocomial and surgical site infections (SSI), usually via autoinfection. NP108 is a cationic antimicrobial polymer composed of generally recognized as safe (GRAS) amino acid building blocks. NP108 is broad spectrum and rapidly bactericidal (3-log kill in ≤3 h), killing bacteria by membrane disruption and cell lysis. NP108, contrary to many antibiotics, shows equally effective antimicrobial activity against a variety of S. aureus (MIC100 = 8 to 500 mg/liter) and S. epidermidis (MIC100 = 4 to 8 mg/liter) isolates, whether exponentially growing or in stationary phase. NP108 is antimicrobially active under nutrient-limiting conditions similar to those found in the anterior nares (MIC100 = 8 mg/liter) and kills antibiotic-resilient small colony variants (MIC100 = 32 mg/liter) and S. aureus biofilms (prevention, MIC100 = 1 to 4 mg/liter; eradication, MIC100 ≥ 31.25 mg/liter). NP108 is active against isolates of S. aureus resistant to the current standard-of-care decolonization agent, mupirocin, with no significant increase in the MIC100 NP108 is water soluble and has been formulated into compatible aqueous gel vehicles for human use in which antimicrobial efficacy is retained (2.0% [wt/vol]). NP108 is a potential nonantibiotic antimicrobial alternative to antibiotics for the nasal decolonization of S. aureus, with clear advantages in its mechanism of action over the existing gold standard, mupirocin.

RESUMO

The study examined a new child report measure of maternal support following child sexual abuse. One hundred and forty-six mother-child dyads presenting for a forensic evaluation completed assessments including standardized measures of adjustment. Child participants also responded to 32 items considered for inclusion in a new measure, the Maternal Support Questionnaire-Child Report (MSQ-CR). Exploratory factor analysis of the Maternal Support Questionnaire-Child Report resulted in a three factor, 20-item solution: Emotional Support (9 items), Skeptical Preoccupation (5 items), and Protection/Retaliation (6 items). Each factor demonstrated adequate internal consistency. Construct and concurrent validity of the new measure were supported in comparison to other trauma-specific measures. The Maternal Support Questionnaire-Child Report demonstrated sound psychometric properties. Future research is needed to determine whether the Maternal Support Questionnaire-Child Report provides a more sensitive approximation of maternal support following disclosure of sexual abuse, relative to measures of global parent-child relations and to contextualize discrepancies between mother and child ratings of maternal support.
