RESUMO

BACKGROUND: Good health in the early years lays the foundation for lifelong health. Children with experience of extraparental care (eg, foster, kinship, residential) have poorer outcomes than children without such experience. Common health conditions in high-income countries differ from those in low-income and middle-income countries. Health conditions also vary substantially with age. The literature examining physical health conditions affecting young care-experienced children in high-income countries has not been previously reviewed. This review addresses this gap to better understand the health needs of these children. METHODS: In this scoping review, we used a broad range of search terms in MEDLINE, CINAHL, and Web of Science Core Collection databases to identify studies of (1) care-experienced children, (2) physical health outcomes, and (3) children aged 6 years or younger. Intersecting search results were retained for screening. Results were restricted to peer-reviewed journal articles indexed before Sept 1, 2022, with titles in English. Grey literature was excluded. No restriction was placed on study design. Results were narratively synthesised and categorised by health condition. FINDINGS: Searches yielded 15 639 results, and 33 articles were ultimately included, covering 11 countries. Studies were concentrated in the USA (n=18, 55%) and Europe (including UK; n=10, 30%). Most studies investigated a specific health outcome or set of outcomes (n=23, 70%) with many of the remaining studies carrying out broader health reviews (n=8, 24%). Height and weight were the most frequently reported outcomes (n=10, 30%) followed by vision (n=7, 21%) and dental health (n=7, 21%). Nine studies (27%) compared outcomes in care-experienced children with outcomes in non-care-experienced controls. Synthesis of results identified poor physical development, poor dental health, low rates of immunisation, dermatological conditions, and anaemia to be substantial health problems among young children with care experience. INTERPRETATION: Poor physical development and anaemia suggest efforts are required to improve care-experienced children's diet. Dermatological conditions and poor dental health can be managed by additional health-care support to care-experienced children and caregivers. A strength of this work is the standardised methodology. This work is limited by the exclusion of grey literature and restriction to high-income countries.

RESUMO

OBJECTIVES: We investigated the acoustic startle reflex in recently concussed adolescent athletes compared to healthy controls and those with concussion history (>1 year prior) but no current symptoms. We hypothesized that individuals with recent concussion would have a suppressed startle response compared to healthy controls. METHODS: We conducted a cross-sectional study on 49 adolescent athletes with a recent concussion (n = 20; age: 14.6 ± 1.6 years; 60% female), a concussion history > 1 year prior (n = 16; age: 14.8 ± 2.0 years; 44% female), and healthy controls (n = 13; age: 13.3 ± 2.8 years; 54% female). We measured the eyeblink of the general startle reflex via electromyography activity of the orbicularis oculi muscle using electrodes placed under the right eye. Measurement sessions included twelve 103 decibel acoustic startle probes ~50 milliseconds in duration delivered ~15-25 seconds apart. The primary dependent variable was mean startle magnitude (µV), and group was the primary independent variable. We used a one-way analysis of variance followed by a Tukey post hoc test to compare mean startle magnitude between groups. RESULTS: Mean startle magnitude significantly differed (F = 5.49, P = .007) among the groups. Mean startle magnitude was significantly suppressed for the concussion (P = .01) and concussion history groups (P = .02) compared to healthy controls. There was no significant difference between the recent concussion and concussion history groups (P = 1.00). CONCLUSION: Our results provide novel evidence for startle suppression in adolescent athletes following concussion. The concussion history group had an attenuated startle response beyond resolution of their recovery, suggesting there may be lingering physiological dysfunction.

RESUMO

Background: Existing work proposes that people with higher social anxiety symptoms and sociability alcohol expectancies believe alcohol can lower their anxiety. However, studies have primarily analyzed retrospective reports, not anticipatory motives. Since predictions of future emotion (i.e., affective forecasts) strongly influence behavior, it is critical to understand how people predict alcohol will influence their anxiety. Additionally, intolerance of uncertainty (IU) is related to the use of alcohol as a coping tool, but there is a dearth of work testing whether IU influences alcohol-related forecasts. Objectives: Utilizing a novel affective forecasting task, we tested the prediction that social anxiety symptoms, sociability alcohol expectancies, and IU would relate to predictions about alcohol use. In an initial study and preregistered replication, participants imagined themselves in stressful social scenarios and forecasted how anxious they would feel when drinking and when sober. In the replication, participants also forecasted whether they would drink in the imagined scenarios. Results: Contrary to hypotheses, social anxiety symptoms and IU did not significantly predict higher forecasted anxiety across studies, nor did they predict forecasted drinking. Exploratory analyses showed that participants with higher sociability alcohol expectancies forecasted being more likely to drink, and forecasted feeling less anxious when drinking (versus being sober). Even after statistically controlling for social anxiety, the effect of sociability expectancies remained significant in predicting forecasted anxiety and forecasted drinking. Conclusions: Clinicians could consider specifically targeting sociability expectancies for alcohol use difficulties, and future research should continue utilizing affective forecasting paradigms to test links between social anxiety, alcohol expectancies, and alcohol-use problems.

RESUMO

BACKGROUND: Fidaxomicin, a narrow-spectrum antibiotic approved for Clostridioides (Clostridium) difficile infection (CDI) in adults, is associated with lower rates of recurrence than vancomycin; however, pediatric data are limited. This multicenter, investigator-blind, phase 3, parallel-group trial assessed the safety and efficacy of fidaxomicin in children. METHODS: Patients aged <18 years with confirmed CDI were randomized 2:1 to 10 days of treatment with fidaxomicin (suspension or tablets, twice daily) or vancomycin (suspension or tablets, 4 times daily). Safety assessments included treatment-emergent adverse events. The primary efficacy end point was confirmed clinical response (CCR), 2 days after the end of treatment (EOT). Secondary end points included global cure (GC; CCR without CDI recurrence) 30 days after EOT (end of study; EOS). Plasma and stool concentrations of fidaxomicin and its active metabolite OP-1118 were measured. RESULTS: Of 148 patients randomized, 142 were treated (30 <2 years old). The proportion of participants with treatment-emergent adverse events was similar with fidaxomicin (73.5%) and vancomycin (75.0%). Of 3 deaths in the fidaxomicin arm during the study, none were CDI or treatment related. The rate of CCR at 2 days after EOT was 77.6% (76 of 98 patients) with fidaxomicin and 70.5% (31 of 44) with vancomycin, whereas the rate of GC at EOS was significantly higher in participants receiving fidaxomicin (68.4% vs 50.0%; adjusted treatment difference, 18.8%; 95% confidence interval, 1.5%-35.3%). Systemic absorption of fidaxomicin and OP-1118 was minimal, and stool concentrations were high. CONCLUSIONS: Compared with vancomycin, fidaxomicin was well tolerated and demonstrated significantly higher rates of GC in children and adolescents with CDI. CLINICAL TRIALS REGISTRATION: NCT02218372.

RESUMO

BACKGROUND: The selection of later-line treatment for older patients with AJCC (version 7) stage IV non-small cell lung cancer (NSCLC) remains controversial. Nanoparticle albumin-bound (nab)-paclitaxel is approved with carboplatin for the first-line treatment of patients with NSCLC and subgroup analysis of phase 3 data has suggested superior survival in older patients. METHODS: The authors conducted a phase 2 study of nab-paclitaxel in 42 patients aged ≥70 years who had been treated previously with a platinum doublet regimen; patients also could have received a PD-1 inhibitor. The primary endpoint of the current study was grade 3 to 5 toxicity (according to the National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]). In addition to response rate, progression-free survival (PFS), and overall survival (OS), geriatric assessments also were performed before and during treatment, associations between baseline sarcopenia and outcomes were explored, and changes in T lymphocyte p16 before and during treatment were measured. The authors also performed a retrospective subgroup analysis of 19 older patients who were treated with nab-paclitaxel as part of a larger, randomized, phase 2 study; data were not combined. RESULTS: The rate of grade 3 to 5 toxicities was 33.7%. The most common grade 3 to 5 toxicities were decreased white blood cell count (11.9%), neutropenia (9.5%), and fatigue (11.9%). The response rate was 34.2% (2.6% complete response rate and 31.6% partial response rate). The median PFS was 5.2 months and the median OS was 9.3 months. Adverse prognostic factors were common: 42% of patients were frail and 39% of patients were prefrail, whereas 21% had an Eastern Cooperative Oncology Group performance status of 2 and 27% were sarcopenic. Only frailty was found to be predictive of inferior survival. A subgroup analysis of 19 older patients treated with nab-paclitaxel alone in a prior trial demonstrated a response rate of 15.8%, a PFS of 4.2 months, and an OS of 13.6 months. CONCLUSIONS: Fit and prefrail older patients with stage IV NSCLC should be considered for treatment with nab-paclitaxel after disease progression with doublet chemotherapy.

RESUMO

Nationally representative data on mental health disorder prevalence are critical to set informed mental health priorities and policies. Data indicating mental health diagnoses within our nation's veteran population treated at the Veterans Health Administration (VHA) are available, but have yet to be examined for changing trends to inform both VHA and community care. We use VHA national program evaluation data from a time of increasing military enrollment (2007) to troop draw down (2013) to examine changes over time in the number of diagnoses in veterans receiving VHA services. The number of veterans in all diagnostic categories increased during our study period with the smallest increase in psychotic disorders (8%) and the largest in posttraumatic stress disorder (71%). Trends in behavioral health diagnoses among veterans have important implications for policy and clinician competencies within VHA and community providers as veteran mental health care needs change.

RESUMO

OBJECTIVE: To evaluate the analgesic efficacy and safety of ASP8477 in patients with peripheral neuropathic pain (PNP). DESIGN: Enriched enrollment randomized withdrawal. SETTING: Centers in Poland (four), Czech Republic (six), and the United Kingdom (two). SUBJECTS: Patients aged 18 years or older with PNP resulting from painful diabetic peripheral neuropathy or postherpetic neuralgia. METHODS: A four-week screening period followed by a single-blind period (six-day dose titration and three-week maintenance period with ASP8477 [20/30 mg BID]). Treatment responders (defined as a ≥30% decrease in the mean average daily pain intensity during the last three days of the single-blind period) were stratified by disease and randomized to receive placebo or continue ASP8477 during a three-week, double-blind, randomized withdrawal period. The primary end point was change in mean 24-hour average numeric pain rating scale (NPRS) from baseline to end of double-blind period. RESULTS: Among 132 patients who enrolled, 116 entered the single-blind period and 63 (ASP8477, N = 31; placebo, N = 32) completed the double-blind period. There was no difference in mean 24-hour average NPRS score (P = 0.644) or in time-to-treatment failure (P = 0.485) between ASP8477 and placebo. During the single-blind period, 57.8% of patients were treatment responders. ASP8477 was well tolerated. During the single-blind period, 22% of patients experienced at least one treatment-related adverse event (TEAE); during the double-blind period, 8% in the ASP8477 arm and 18% in the placebo arm experienced at least one TEAE. CONCLUSIONS: ASP8477 was well tolerated in patients with PNP; however, ASP8477 did not demonstrate a significant treatment difference compared with placebo.

RESUMO

We sought to explore clinical factors associated with successful transition from Assertive Community Treatment to less intensive clinical services. Mixed-method observational follow up study of veterans discharged from three VA-affiliated ACT teams to less intensive clinical services. Of the 240 veterans in ACT, 9% (n = 21) were discharged during the study period. Among the 11 of 21 discharged veterans who enrolled in the follow up study, reason for discharge, designated by the veteran's primary clinician at the time of discharge, predicted outcomes (p = 0.02) at 9 months, with "disengagement" as a reason for discharge predicting poorer outcomes. Six of 11 veterans experienced poor outcomes at 9 months, including incarceration and substance use relapse. ACT clinicians rarely discharge clients. Many clients may experience negative clinical events following ACT discharge, and clients may be difficult to follow post-discharge. Client disengagement from ACT may indicate higher likelihood of poor outcomes following discharge to less intensive clinical services.

RESUMO

Unconditioned responding (UCR) to a naturally aversive stimulus is associated with defensive responding to a conditioned threat cue (CS+) and a conditioned safety cue (CS-) in trauma-exposed individuals during fear acquisition. However, the relationships of UCR with defensive responses during extinction training, posttraumatic stress disorder (PTSD) symptom severity, and fearful traits in trauma-exposed individuals are not known. In a sample of 100 trauma-exposed adults with a continuum of PTSD severity, we recorded startle responses and skin conductance responses (SCR) during fear acquisition and extinction training using a 140 psi, 250-ms air blast to the larynx as the unconditioned stimulus. We explored dimensional associations of two different measures of UCR (unconditioned startle and unconditioned SCR) with conditioned defensive responding to CS+ and CS-, conditioned fear (CS+ minus CS-), PTSD symptom severity, and a measure of fearful traits (composite of fear survey schedule, anxiety sensitivity index, and Connor-Davidson resilience scale). Unconditioned startle was positively associated with startle potentiation to the threat cue and the safety cue across both learning phases (CS+ Acquisition, CS- Acquisition, CS+ Extinction Training, CS- Extinction Training) and with fearful traits. Unconditioned SCR was positively associated with SCR to the CS+ and CS- and SCR difference score during Acquisition. Neither type of UCR was associated with PTSD symptom severity. Our findings suggest that UCR, particularly unconditioned startle to a naturally aversive stimulus, may inform research on biomarkers and treatment targets for symptoms of pervasive and persistent fear in trauma-exposed individuals.

RESUMO

Individuals living with psychosis are often underserved in the United States, partly due to the dearth of providers trained in evidence-based practices for this population. One such practice is Cognitive Behavioral Therapy for psychosis, which the Substance Abuse and Mental Health Services Administration has identified as a standard of care for this population. The explosion of telehealth, in large part due to the COVID-19 pandemic, has led to increased opportunities for virtual psychotherapy. Telehealth offers a number of benefits, such as the ability to address service inequities, including lack of access to a local provider well-trained in the modality of therapy needed. The current article describes the National Psychosis Telehealth Program within the National Expert Consultation and Specialized Services (formerly VA National Telemental Health Center) program, U.S. Department of Veterans Affairs. The goal of this telehealth program is to utilize an expert consultation model and offer a remote individual, time-limited Cognitive Behavioral Therapy for psychosis protocol to Veterans across the nation in order to decrease access disparities to this relatively scarce service. We share our initiation activities and lessons learned as we developed this program in hopes of encouraging others to consider similar efforts at their sites. We also include a typical, complex case that serves to illustrate the challenges and benefits of this approach. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Within the Veterans Affairs (VA), management of self-harm is a major clinical priority. However, there is limited information on risks for self-harm among VA patients with emerging psychotic disorders relative to VA patients with other emerging mental health conditions. Using information from fiscal years 2010 through 2018, a national cohort of VA patients 30 or younger was classified based on mental health diagnoses into three groups: 1) early episode psychosis (EEP), 2) non-early episode psychosis mental health (non-EEP MH), or 3) no mental health (no MH). Analyses focused on cohort members' risk for all-cause mortality, suicide mortality, and non-fatal suicide attempts (NFSA) during the year following initial diagnosis of mental health conditions (or first year of VA care, for the no MH group). In unadjusted analyses, the EEP group had elevated rates of all-cause mortality, suicide mortality, and NFSA relative to the non-EEP MH and no MH groups and the non-EEP MH had elevated rates of all-cause mortality, suicide mortality, and NFSA relative to the no MH group. After adjusting for demographics and care receipt, EEP status was unrelated to all-cause mortality but associated with increased suicide mortality risk and NFSA. Non-EEP MH status was associated with reduced risk of all-cause mortality but increased risk for NFSA. In the year following first diagnosis, VA patients with EEP are at increased risk for suicide mortality and self-harm even after accounting for other risk factors. Clinical services targeting this crucial time can help promote safety for this vulnerable group.

RESUMO

Research using psychophysiological methods holds great promise for refining clinical assessment, identifying risk factors, and informing treatment. Unfortunately, unique methodological features of existing approaches limit inclusive research participation and, consequently, generalizability. This brief overview and commentary provides a snapshot of the current state of representation in clinical psychophysiology, with a focus on the forms and consequences of ongoing exclusion of Black participants. We illustrate issues of inequity and exclusion that are unique to clinical psychophysiology, considering intersections among social constructions of Blackness and biased design of current technology used to measure electroencephalography, skin conductance, and other signals. We then highlight work by groups dedicated to quantifying and addressing these limitations. We discuss the need for reflection and input from a wider variety of stakeholders to develop and refine new technologies, given the risk of further widening disparities. Finally, we provide broad recommendations for clinical psychophysiology research.

RESUMO

Stress response dampening is an important motive for alcohol use. However, stress reduction via alcohol (alcohol SRD) is observed inconsistently in the laboratory, and this has raised questions about the precise mechanisms and boundary conditions for these effects. Emerging evidence indicates that alcohol SRD may be observed selectively during uncertain but not certain threats. In a final sample of 89 participants, we measured stress response via potentiation of defensive startle reflex in response to threat of shock in blocks with certain (low and high) and uncertain shock intensity. Our alcohol-administration procedure produced blood alcohol concentrations (BACs) across a broad range (0.00%-0.12%) across participants. Increasing BACs were associated with linearly decreasing startle potentiation and self-reported anxiety. This SRD effect was greater during uncertain than certain threat. More broadly, these results suggest that distinct mechanisms are involved in response to threats of uncertain intensity and threats of certain intensity.

RESUMO

Consumers' satisfaction with inpatient mental health care is recognized as a key quality indicator that prospectively predicts functional and clinical outcomes. Coercive treatment experience is a frequently cited source of dissatisfaction with inpatient care, yet more research is needed to understand the factors that influence consumers' perceptions of coercion and its effects on satisfaction, including potential "downstream" effects of past coercive events on current treatment satisfaction. The current study examined associations between objective and subjective indices of coercive treatments and patients' satisfaction with care in a psychiatric inpatient sample (N = 240). Lower satisfaction ratings were independently associated with three coercive treatment variables: current involuntary admission, perceived coercion during current admission, and self-reported history of being refused a requested medication. Albeit preliminary, these results document associations between patients' satisfaction ratings and their subjective experiences of coercion during both current and prior hospitalizations.

RESUMO

Persistent fear is a cardinal feature of posttraumatic stress disorder (PTSD), and deficient fear extinction retention is a proposed illness mechanism and target of exposure-based therapy. However, evidence for deficient fear extinction in PTSD has been mixed using laboratory paradigms, which may relate to underidentified methodological variation across studies. We reviewed the literature to identify parameters that differ across studies of fear extinction retention in PTSD. We then performed Multiverse Analysis in a new sample, to quantify the impact of those methodological parameters on statistical findings. In 25 PTSD patients (15 female) and 36 trauma-exposed non-PTSD controls (TENC) (20 female), we recorded skin conductance response (SCR) during fear acquisition and extinction learning (day 1) and extinction recall (day 2). A first Multiverse Analysis examined the effects of methodological parameters identified by the literature review on comparisons of SCR-based fear extinction retention in PTSD versus TENC. A second Multiverse Analysis examined the effects of those methodological parameters on comparisons of SCR to a danger cue (CS+) versus safety cue (CS-) during fear acquisition. Both the literature review and the Multiverse Analysis yielded inconsistent findings for fear extinction retention in PTSD versus TENC, and most analyses found no statistically significant group difference. By contrast, significantly elevated SCR to CS+ versus CS- was consistently found across all analyses in the literature review and the Multiverse Analysis of new data. We discuss methodological parameters that may most contribute to inconsistent findings of fear extinction retention deficit in PTSD and implications for future clinical research.

RESUMO

Tobacco smoking imposes a staggering burden on public health, underscoring the urgency of developing a deeper understanding of the processes that maintain addiction. Clinical and experience-sampling data highlight the importance of anxious withdrawal symptoms, but the underlying neurobiology has remained elusive. Mechanistic work in animals implicates the central extended amygdala (EAc)-including the central nucleus of the amygdala and the neighboring bed nucleus of the stria terminalis-but the translational relevance of these discoveries remains unexplored. Here we leveraged a randomized trial design, well-established threat-anticipation paradigm, and multidimensional battery of assessments to understand the consequences of 24-hour nicotine abstinence. The threat-anticipation paradigm had the expected consequences, amplifying subjective distress and arousal, and recruiting the canonical threat-anticipation network. Abstinence increased smoking urges and withdrawal symptoms, and potentiated threat-evoked distress, but had negligible consequences for EAc threat reactivity, raising questions about the translational relevance of prominent animal and human models of addiction. These observations provide a framework for conceptualizing nicotine abstinence and withdrawal, with implications for basic, translational, and clinical science.

RESUMO

BACKGROUND: Low-dose CT (LDCT) is underused in Arkansas for lung cancer screening, a rural state with a high incidence of lung cancer. The objective was to determine whether offering free LDCT increased the number of high-risk individuals screened in a rural catchment area. METHODS: There were 5,402 patients enrolled in screening at Highlands Oncology, a community oncology clinic in Northwest Arkansas, from 2013 to 2020. Screenings were separated into time periods: period 1 (10 months for-fee), period 2 (10 months free with targeted advertisements and primary care outreach), and period 3 (62 months free with only primary care outreach). In all, 5,035 high-risk participants were eligible for analysis based on National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology. Enrollment rates, incidence densities (IDs), Cox proportional hazard models, and Kaplan-Meier curves were performed to investigate differences between enrollment periods and high-risk groups. RESULTS: Patient volume increased drastically once screenings were offered free of charge (period 1 = 4.6 versus period 2 = 66.0 and period 3 = 69.8 average patients per month). Incidence density per 1,000 person-years increased through each period (IDPeriod 1 = 17.2; IDPeriod 2 = 20.8; IDPeriod 3 = 25.5 cases). Cox models revealed significant differences in lung cancer risk between high-risk groups (P = .012) but not enrollment periods (P = .19). Kaplan-Meier lung cancer-free probabilities differed significantly between high-risk groups (log-rank P = .00068) but not enrollment periods (log-rank P = .18). CONCLUSIONS: This study suggests that eligible patients are more receptive to free LDCT screening, despite most insurances not having a required copay for eligible patients.

RESUMO

Importance: People with serious mental illness (SMI), defined as a diagnosis of schizophrenia spectrum disorder, bipolar disorder, or disabling major depressive disorder) die approximately 10 to 25 years earlier than the general population. Objective: To develop the first-ever lived experience-led research agenda to address early mortality in people with SMI. Evidence Review: A virtual 2-day roundtable comprising 40 individuals convened on May 24 and May 26, 2022, and used a virtual Delphi method to arrive at expert group consensus. Participants responded to 6 rounds of virtual Delphi discussion via email that prioritized research topics and agreement on recommendations. The roundtable was composed of individuals with lived experience of mental health and/or substance misuse, peer support specialists, recovery coaches, parents and caregivers of people with SMI, researchers and clinician-scientists with and without lived experience, policy makers, and patient-led organizations. Twenty-two of 28 (78.6%) of the authors who provided data represented people with lived experiences. Roundtable members were selected by reviewing the peer-reviewed and gray literature on early mortality and SMI, direct email, and snowball sampling. Findings: The following recommendations are presented in order of priority as identified by the roundtable participants: (1) improve the empirical understanding of the direct and indirect social and biological contributions of trauma on morbidity and early mortality; (2) advance the role of family, extended families, and informal supporters; (3) recognize the importance of co-occurring disorders and early mortality; (4) redefine clinical education to reduce stigma and support clinicians through technological advancements to improve diagnostic accuracy; (5) examine outcomes meaningful to people with an SMI diagnosis, such as loneliness and sense of belonging, and stigma and their complex relationship with early mortality; (6) advance the science of pharmaceuticals, drug discovery, and choice in medication use; (7) use precision medicine to inform treatment; and (8) redefine the terms system literacy and health literacy. Conclusions and Relevance: The recommendations of this roundtable are a starting point for changing practice and highlighting lived experience-led research priorities as an option to move the field forward.

RESUMO

Collaborative assessment utilizes psychological testing to help people make positive changes in their lives. Limited research has evaluated the utility of collaborative assessment for persons with serious mental illness. This case example uses the Personality Assessment Inventory to illustrate the usefulness of collaborative assessment with a person with serious mental illness. This approach informed not only diagnostic considerations but also revealed the client's current level of distress, contributed to enhanced therapeutic alliance, and directly pointed to psychiatric rehabilitation strategies.
