RESUMO

Background: Currently, the capacity to provide buprenorphine treatment (BT) is not sufficient to treat the growing number of people in the United States with opioid use disorder (OUD). We sought to examine participant retention in care rates of primary care delivered BT programs and to describe factors associated with retention/attrition for participants receiving BT in this setting.Objectives: A PRISMA-guided search of various databases was performed to identify the articles focusing on efficacy of BT treatment and OUD.Method: A systematic literature search identified 15 studies examining retention in care in the primary care setting between 2002 and 2020. Random effects meta-regression were used to identify retention rates across studies.Results: Retention rates decreased across time with a mean 0.52 rate at one year. Several factors were found to be related to retention, including: race, use of other drugs, receipt of counseling, and previous treatment with buprenorphine.Conclusions: While we only investigate BT through primary care, our findings indicate retention rates are equivalent to the rates reported in the specialty care literature. More work is needed to examine factors that may impact primary care delivered BT specifically and differentiate participants that may benefit from care delivered in specialty over primary care as well as the converse.

RESUMO

Objective: Pain, stress, and diabetes mellitus (DM) are common complaints for Guatemalans seeking health care. Because acupuncture therapy (AT) is a low-cost, effective treatment for these concerns, it was offered to Guatemalans during a health care mission as an adjunct to primary care. The purpose of this study was to gather feedback about providing AT in this context and to describe the lessons that were learned. Materials and Methods: A pretest single-arm exploratory study design was used, collecting demographic data and administering a pretest to patients referred for AT. Patients received AT according to presenting symptoms, except patients with DM, who were treated with a previously developed auricular AT protocol. After AT, all patients received adhesive seeds for self-administered auricular acupressure, along with a printed diagram, showing where and how to apply them, and a symptom-tracking form. Results: AT was given to 11 patients (1 had DM; 10 did not). Most were female (9; 82%), older (average 59.27 years; range: 40-81 years), and had little education (average 4 years; range: 0-12 years). Complaints were pain (11; 100%), insomnia (6; 55%), anxiety (4; 36%), depression (7; 64%), and stress (3; 27%). More than 50% had seen health care providers (6; 55%). One person had AT previously and 3 people requested more information about AT before receiving it. Conclusions: Reporting high symptom burdens, most patients were unfamiliar with AT. AT ceased when the licensed acupuncturist contracted COVID. Patients will be followed in 2023 and AT will be given to collect data on feasibility, satisfaction, and possible implementation.

RESUMO

Purpose: We sought to evaluate the relationship between adverse childhood experiences (ACEs) and tobacco use, to assess the intersection of sexual orientation or gender identity (SOGI), and to explore risk and protective aspects of mental, social, and community health. Methods: This was a secondary analysis of the sexual and gender minorities (SGM) subsample (n = 1102) from a 2019 Community Health Needs Assessment. Nested binary logistic regression models were created to evaluate associations between ACEs and type of tobacco use: (1) cigarette use versus no cigarette or electronic nicotine delivery systems (ENDS) use, (2) ENDS use versus no cigarette or ENDS use, and (3) dual use versus use of either cigarettes or ENDS. Results: The sample population that reported four or more ACEs and ENDS use had statistically significant adjusted odds ratios (aORs) when adjusting the models for sociodemographic variables (aOR = 2.55; 95% confidence intervals [CIs]: 1.54-4.22), SOGI (aOR = 2.44; 95% CI: 1.46-4.10), current mental health (aOR = 2.23; 95% CI: 1.32-3.75), and social and community health (aOR = 2.19; 95% CI: 1.30-3.71). The sample population that reported poor mental health had statistically significant aORs when adjusting the models for sociodemographic variables, SOGI, and mental health (aOR = 2.26; 95% CI: 1.32-3.89) and social and community health (aOR = 2.06; 95% CI: 1.17-3.54). There was no statistically significant finding related to the other tobacco use variables (tobacco use and dual use). Conclusion: We found that high-risk ACEs were positively associated with cigarette use and ENDS use. SGM populations have differing experiences when considering community and social support.

RESUMO

In the following clinical case of infantile juvenile polyposis syndrome (JPS), administration of a pharmacologic agent sirolimus was associated with reduced disease burden without need for bowel resection. The positive impact included improvement in protein-losing enteropathy, decreased intestinal blood loss, and improved weight gain. In addition, the number of polyps resected per unit time and frequency of upper and lower endoscopic evaluation needed dropped after initiation of sirolimus. This case report describes a positive clinical outcome and discusses the use of sirolimus with aggressive polypectomy as a potential treatment for the rare disease entity of polygenic infantile JPS. Through this case, we aim to emphasize that while administration of this drug may mitigate many sequelae of infantile JPS, it does not appear to eliminate the need for aggressive polypectomy.

RESUMO

BACKGROUND: The association between physical activity and adiposity in preschool-aged children is unclear. OBJECTIVE: To assess the cross-sectional association between objectively measured physical activity and body fat in preschool-aged children. METHODS: In the preschool review in an Australian birth cohort study (n = 1074), mean duration and time accumulated in ≥1-min bouts of physical activity at light-intensity (LPA), moderate- to vigorous-intensity (MVPA) and light- to vigorous-intensity (LMVPA) were computed from accelerometer (ActiGraph GT3X+) data. Percent body fat was assessed by bioelectrical impedance. Associations between physical activity and percent body fat were examined by multiple regression, adjusted for accelerometer wear time, MVPA (in analyses of LPA), maternal body mass index (BMI) and maternal education. RESULTS: A total of 450 participants (n = 450) had valid data. There was evidence of associations between physical activity and adiposity: each additional hour of LVPA was associated with 0.6% (CI95 -0.2%, 1.3%) higher body fat; ≥1-min bouts of LPA was associated with 1.0% (CI95 0.1%, 1.9%) higher body fat; each additional hour of MVPA was associated with -0.8% (CI95 -1.6%, -0.1%) less body fat; and ≥1-min bouts of MVPA was associated with -1.3% (CI95 -2.5%, -0.1%) body fat. CONCLUSIONS: Among a cohort of preschool-aged children, there was evidence that more intensive physical activity assessed by an accelerometer is associated with reduced body fat.

RESUMO

INTRODUCTION: Adverse childhood experiences contribute to both short- and long-term health issues and negative health behaviors that affect the individual as well as families and communities. Exposure to ≥4 of the 11 adverse childhood experiences (high adverse childhood experiences) compounds the problems in later life. This study assesses the associations among tobacco use, adverse childhood experiences, mental health, and community health. METHODS: This study was a secondary data analysis utilizing a large 2019 data set from a Community Health Needs Assessment in Florida (N=14,056). Investigators utilized inferential statistics to determine adverse childhood experiences as a predictor of tobacco use (vaping and cigarette use). In addition, they examined whether a shorter, 2-question adverse childhood experience scale was equivalent to the full scale when predicting tobacco use. RESULTS: The results indicated that parental divorce was the most common household stressor, followed by mental illness and alcoholism. High adverse childhood experiences were found to be most prominent in marginalized individuals. For those individuals experiencing ≥4 adverse childhood experiences, parental divorce continued to rank high, followed by mental illness. Household stressors included emotional and physical abuse as the most prevalent in the ≥4 adverse childhood experience group. High adverse childhood experiences were associated with current cigarette smoking (AOR=1.56) after controlling for individual mental health and social/community health variables. High adverse childhood experiences were also associated with E-cigarette use (AOR=1.81) but not dual cigarette/E-cigarette use. Social and community health was inversely associated with tobacco use. A 2-item adverse childhood experiences measure was sufficient in identifying tobacco users. CONCLUSIONS: Including adverse childhood experiences in community needs assessments provides important information for tobacco control efforts and prevention of chronic disease.

RESUMO

OBJECTIVES: To describe cycling behaviours and examine individual, social and neighbourhood correlates of cycling among children living in socio-economically disadvantaged neighbourhoods. DESIGN: Cross-sectional. METHODS: Mothers of 289 children (46% boys) aged 8-15 (mean 12±2.2) years living in disadvantaged neighbourhoods in Victoria, Australia were surveyed about their child's cycling frequency and duration in a typical week. Perceptions of cycling, cycling ability, cycling behaviours and road safety were proxy- and self-reported by mothers. Shortest road distance from home to school was determined using a Geographic Information System. Multivariable logistic regression analyses examined associations between individual, social and neighbourhood variables and cycling frequency (>once/week) and duration (>60min/week). RESULTS: Overall, 70% of boys and 49% of girls cycled>once/week; rates of cycling for >60min/week were 60% and 32%, respectively. Children had greater odds of cycling>once/week if they enjoyed cycling for fun (OR=13.3, 95%CI=2.0, 86.9). Children had greater odds of cycling for >60min/week if they enjoyed cycling for fun (OR=17.1, 95%CI=1.7, 167.7) or if they were allowed to cycle on main roads (OR=3.2, 95%CI=1.1, 9.1). Children who had to cross several roads to access play areas had lower odds of cycling for >60min/week (OR=0.3, 95%CI=0.1, 0.7). CONCLUSIONS: Future research should investigate strategies to increase children's enjoyment of cycling, independent mobility and safe access by cycling to key destinations such as play areas.

RESUMO

OBJECTIVES: Higher physical activity (PA) levels in adults are associated with lower cardiovascular disease risk, however it is unclear whether this association is evident in children younger than five years. Given that cardiovascular disease has early life origins, this study systematically reviews evidence of associations between PA and cardiovascular disease risk factors among children aged 3-5.5years. DESIGN: Systematic review. METHOD: A systematic search of multiple data bases was conducted to identify published papers reporting associations between any measure of PA and cardiovascular disease risk factors. INCLUSION CRITERIA: English language; peer-reviewed; original quantitative research; mean age or majority of sample to be between 3.0-5.5years. Studies where the sample was characterised by a health condition (e.g. obese, hypertensive) were not eligible for inclusion. RESULTS: Twelve papers met the inclusion criteria. At least one study for each cardiovascular disease risk factor except inflammation was included. PA was not associated with insulin resistance, and inconsistently associated with the remaining cardiovascular disease risk factors. Studies were mostly cross-sectional and methodologically heterogeneous. Longitudinal and experimental study designs and objective measurement of PA may help provide a clearer indication of the interplay between PA and cardiovascular disease risk in the preschool population.

RESUMO

INTRODUCTION: Total volumes of physical activity and sedentary behaviour have been associated with cardio-metabolic risk profiles; however, little research has examined whether patterns of activity (e.g., prolonged bouts, frequency of breaks in sitting) impact cardio-metabolic risk. The aim of this review was to synthesise the evidence concerning associations between activity patterns and cardio-metabolic risk factors in children and adolescents aged 5-19 years. MATERIALS AND METHODS: A systematic search of seven databases was completed in October 2017. Included studies were required to report associations between objectively-measured activity patterns and cardio-metabolic risk factors in children and/or adolescents, and be published between 1980 and 2017. At least two researchers independently screened each study, extracted data, and undertook risk of bias assessments. RESULTS: From the 15,947 articles identified, 29 were included in this review. Twenty-four studies were observational (cross-sectional and/or longitudinal); five were experimental. Ten studies examined physical activity patterns, whilst 19 studies examined sedentary patterns. Only one study examined both physical activity and sedentary time patterns. Considerable variation in definitions of activity patterns made it impossible to identify which activity patterns were most beneficial to children's and adolescents' cardio-metabolic health. However, potential insights and current research gaps were identified. DISCUSSION AND CONCLUSION: A consensus on how to define activity patterns is needed in order to determine which activity patterns are associated with children's and adolescents' cardio-metabolic risk. This will inform future research on the impact of activity patterns on children's and adolescents' short- and longer-term health.

RESUMO

BACKGROUND: Psychological therapy services are often required to demonstrate their effectiveness and are implementing systematic monitoring of patient progress. A system for measuring patient progress might usefully 'inform supervision' and help patients who are not progressing in therapy. AIMS: To examine if continuous monitoring of patient progress through the supervision process was more effective in improving patient outcomes compared with giving feedback to therapists alone in routine NHS psychological therapy. METHOD: Using a stepped wedge randomized controlled design, continuous feedback on patient progress during therapy was given either to the therapist and supervisor to be discussed in clinical supervison (MeMOS condition) or only given to the therapist (S-Sup condition). If a patient failed to progress in the MeMOS condition, an alert was triggered and sent to both the therapist and supervisor. Outcome measures were completed at beginning of therapy, end of therapy and at 6-month follow-up and session-by-session ratings. RESULTS: No differences in clinical outcomes of patients were found between MeMOS and S-Sup conditions. Patients in the MeMOS condition were rated as improving less, and more ill. They received fewer therapy sessions. CONCLUSIONS: Most patients failed to improve in therapy at some point. Patients' recovery was not affected by feeding back outcomes into the supervision process. Therapists rated patients in the S-Sup condition as improving more and being less ill than patients in MeMOS. Those patients in MeMOS had more complex problems.

RESUMO

PURPOSE: Continuous outcome monitoring studies have been conducted by one group of researchers in the United States, mainly in university counselling clinics. We completed a systematic review of continuous outcome monitoring and feedback during psychological therapy and assessed the quality and methodological rigour of existing studies to examine if the findings might be applicable to psychological therapy settings in the United Kingdom. METHODS: An electronic database literature search was carried out on studies on or after 1990 to June 2013 using strict research criteria. Independent ratings of the quality of existing studies were undertaken. RESULTS: Ten studies with original data met inclusion criteria and two meta-analyses. Feedback improves outcomes for clients who are at risk of treatment failure but effect sizes diminish with more severe psychiatric populations. No study has followed up patients to assess maintenance of gains. Study quality is highly variable. Few studies included diagnostic information and details of randomization. Clinical Support Tools are thought to be helpful but how these were used was not described. CONCLUSIONS: Although research in continuous monitoring and feedback of clinical outcomes shows promising results in counselling settings, study quality, and methodological issues set limitations on the generalizability of the findings. PRACTITIONER POINTS: Feedback improves the outcome of therapy for young people with mild problems for those who are at risk of not improving with therapy. Feedback improves outcomes for those with more severe mental health problems but with reduced effect sizes. We do not know if improved outcomes are sustained. The generalizability of the findings may be limited.

RESUMO

BACKGROUND: Morquio A syndrome (or mucopolysaccharidosis IVa) is an ultra-rare multi-organ disease, resulting in significantly impaired functional capacity, mobility and quality of life (QoL). METHODS: This patient-reported outcomes survey evaluated the global burden of Morquio A among adults (≥18 years, N = 27) and children (7-17 years, N = 36), including the impact on mobility, QoL, pain and fatigue. QoL was assessed using the general Health-Related Quality of Life (HRQoL) questionnaire (the EuroQol [EQ]-5D-5L). Pain and pain interference with daily activities were assessed using the Brief Pain Inventory Short Form (BPI-SF) in adults and the Adolescent Pediatric Pain Tool (APPT) in children. Fatigue was assessed by questioning the patients on the number of evenings in a week they felt extremely tired. RESULTS: The clinical data showed a wide heterogeneity in clinical manifestations between patients, with the majority of patients showing differing levels of endurance, short stature, bone and joint abnormalities, abnormal gait and eye problems. Mobility was considerably impaired: 44.4% of children and 85.2% of adult patients were using a wheelchair. High wheelchair reliance significantly reduced QoL. This was mainly driven by reduced scores in the Mobility, Self-care, and Usual Activity domains. The HRQoL utility values were 0.846, 0.582 and 0.057 respectively in adults not using a wheelchair, using a wheelchair only when needed and always using a wheelchair; values were 0.534, 0.664 and -0.180 respectively in children. Employed adult patients had a better HRQoL than unemployed patients (HRQoL utility value 0.640 vs. 0.275, respectively).64% of children and 74% of adult patients had joint pain; fatigue was reported by 69% of children and 63% of adults. Overall, increased mobility was associated with more severe and widespread pain and more fatigue. CONCLUSIONS: The HRQoL of Morquio A patients is mainly driven by the ability to remain independently mobile without becoming wheelchair dependent. Their QoL reduces dramatically if they always have to use their wheelchair. Even a slightly better mobility (wheelchair use only when needed) greatly improves QoL. Maintenance of functional capacity and mobility paired with better pain management are likely to improve QoL.

RESUMO

Abstract This international survey performed by direct personal interview or mail evaluated the global burden among primary caregivers of patients with Morquio A syndrome. Collected outcomes included self-reported time spent on caregiving, proportion of daily activities (from the Mucopolysaccharidosis Health Assessment Questionnaire) requiring caregiver assistance, and how the patient's age and wheelchair use affect these. In addition, the impact of caregiving on the caregivers' relationship with family and friends, physical and mental health, and employment status and income was evaluated. Caregiver burden increased with disease progression. Adult patients always using a wheelchair required substantially more caregiving time and complete assistance with a larger proportion of daily activities than more mobile patients. In children, this was less apparent. Caregivers suffered physically and emotionally and their family and social life and financial situation were considerably impacted. Improvements in patient mobility may substantially reduce the level of caregiver support and the burden of caregiving.

RESUMO

OBJECTIVE: The aim of this study was to determine the characteristics and referral pattern of children and adolescents with mental health problems, substance misuse and comorbidity presenting to the emergency department (ED) of a large public hospital. METHOD: A file audit of the ED information system was conducted over a 12 month period. Outcome measures included age, gender, diagnostic presentation, assessment, referral and disposal. RESULTS: Forty-four substance misuse, 128 mental health and 82 comorbidity presentations were identified; 80% required treatment within 30 minutes. Few substance misuse cases were seen by mental health services and no substance misuse cases were referred for mental health service assessment. All mental health and comorbidity cases were seen by mental health services; 41% were referred to outpatient and 18% to inpatient services. Those with mental health problems displayed high levels of self-mutilation, and those with comorbidity displayed high levels of self-mutilation and substance misuse. Alcohol use was common in the substance misuse group, and over the counter or prescription medications were abused by the mental health and comorbidity groups. CONCLUSIONS: This age group places a high demand on the ED. All children and adolescents with recognized mental health symptoms were seen by mental health services, but those with substance misuse were not. Given the long-term problems associated with substance misuse, this is a missed opportunity for intervention.

RESUMO

BACKGROUND AND OBJECTIVES: Routine pretreatment breast magnetic resonance imaging in newly diagnosed cancer patients remains controversial. We assess MRI accuracy and influence on mastectomy decisions after institution of standardized pretreatment MRI. METHODS: A prospectively collected database of 74 consecutive new invasive breast cancer patients with pretreatment breast MRI was reviewed for treatment choice, radiologic, and pathologic results. Thirty-eight of 72 patients with available surgical records underwent mastectomy. Mastectomy preoperative and operative electronic records were reviewed for treatment decision analysis. RESULTS: Seventeen of 72 (23.6%) invasive breast cancer patients were likely influenced to undergo mastectomy by new information from MRI. MRI reported that the multifocal/multicentric (MF/MC) rate was 20 of 72 (27.8%) versus 19 of 72 (26.4%) by surgical pathology. MRI sensitivity for MF/MC disease was 89.5% versus 11.8% for mammography. MRI specificity was 84.2%. All three false positives declined recommended preoperative biopsies. MRI MF/MC diagnosis highly correlated with pathology results, P < 0.001. CONCLUSIONS: Increased mastectomy rate from 29 to 52.8% after standardization of pre-treatment breast MRI for invasive cancer is largely due to MRI findings of increased extent of disease. These MRI findings correlate well with pathologic findings and appear to justify the performance of mastectomies in these patients.

RESUMO

BACKGROUND AND RATIONALE: Research interests regarding the psychopharmacology of salvinorin A have been motivated by the recreational use and widespread media focus on the hallucinogenic plant, Salvia divinorum. Additionally, kappa opioid (KOP) receptor ligands may have therapeutic potential in the treatment of some neuropsychiatric conditions, including drug dependence and mood disorders. Salvinorin A is a selective KOP agonist, but only a few studies have explored the discriminative stimulus effects of this compound. OBJECTIVE: This study compared the discriminative stimulus effects of salvinorin A and two synthetic derivatives of salvinorin B to the KOP agonists, U69,593 and U50,488. MATERIALS AND METHODS: Sixteen male Sprague-Dawley rats trained to discriminate U69,593 (0.13 mg/kg, s.c., N = 8) or U50,488 (3.0 mg/kg, i.p., N = 8) under a fixed-ratio 20 schedule of food reinforcement were administered substitution tests with salvinorin A (0.125-3.0 mg/kg, i.p.). The animals trained to discriminate U69,593 were also administered substitution tests with salvinorin B ethoxymethyl ether (0.005-0.10 mg/kg, i.p.) and salvinorin B methoxymethyl ether (0.03-0.10 mg/kg, i.p.). Another eight rats were trained to discriminate 2.0 mg/kg salvinorin A and tested with U69,593 (0.04-0.32 mg/kg) and U50,488 (0.4-3.2 mg/kg). RESULTS: Salvinorin A and both synthetic derivatives of salvinorin B substituted completely for U69,593. Additionally, cross-generalization was observed between salvinorin A and both KOP agonists. CONCLUSION: These findings support previous reports indicating that the discriminative stimulus effects of salvinorin A are mediated by kappa receptors. Future studies may assist in the development and screening of salvinorin A analogs for potential pharmacotherapy.
