RESUMO

OBJECTIVE: To examine the efficacy of the parent-led intervention Supportive Parenting for Anxious Childhood Emotions (SPACE) relative to a low-dose version of the protocol among children and adolescents with clinically significant anxiety and/or obsessive-compulsive disorder (OCD). METHOD: 68 youth (7-17) with anxiety/OCD and their parents were randomized to receive 12 weekly telehealth SPACE sessions (SPACE-Standard) or bibliotherapy plus 4 telehealth sessions over 12 weeks (SPACE-light). After screening, assessments were conducted via videoconferencing at baseline, post-treatment, and one-month follow-up. Independent evaluators were blind to treatment condition. RESULTS: Treatment condition did not predict whether a participant responded to the intervention (SPACE-Standard = 70%; SPACE-Light = 68%), nor was treatment condition a predictor of anxiety severity, parent-reported anxiety, or parent-/child-reported functional impairment at post-treatment or one-month follow-up. Youth in SPACE-Light self-reported higher post-treatment anxiety than youth in SPACE-standard, though this was no longer significant at one-month follow-up. Parent-reported family accommodation total change scores were associated with anxiety severity at post-treatment across both arms. CONCLUSION: This is the second randomized controlled trial (RCT) evaluating SPACE and provides further support for the efficacy of this intervention both in standard and low-dose formats. This study provides support for parent-led anxiety treatment targeting family accommodation as a primary mechanism of change and extends evidence of efficacy to a more clinically diverse sample.

RESUMO

Nonalcoholic steatohepatitis (NASH) is a pathological manifestation with a progressive incidence in response to the epidemic of hepatic steatosis caused primarily by excessive energy intake. The present study unravels affected biological processes and functions by the presence of NASH in rats using a label-free quantitative proteomic strategy. NASH was induced by a Western high-sugar and high-fat diet for 20 weeks. The liver tissue was collected for histology and for a mass spectrometry-based proteomic protocol. The NASH group showed severe lipidosis, hepatocyte ballooning, and the presence of collagen deposition. Among upregulated proteins in NASH perilipin-2 (Plin-2; F6QBA3; difference [diff]: 2.29), ferritin heavy (Fth1; Q66HI5; diff: 2.19) and light (Ftl1; P02793; diff: 1.75) chains, macrophage migration inhibitory factor 1 (Mif; P30904; diff: 1.69), and fibronectin (Fn1; F1LST1; diff: 0.35) were observed, whereas among downregulated proteins, plectin (Q6S399; diff: -3.34), some Cyp2 family proteins of the cytochrome P450 complex, glutathione S-transferases, flavin-containing monooxygenase 1 (Fmo1; P36365; diff: -2.08), acetyl-CoA acetyltransferase 2 (Acat2; Q5XI22; diff: -2.25), acyl-CoA oxidase 2 (Acox2; F1LNW3; diff: -1.59), and acyl-CoA oxidase 3 (Acox3; F1M9A7; diff: -2.41) were observed. Also, biological processes and functions such as LPS/IL-1 inhibition of RXR, fatty acid metabolism, Nrf2-mediated oxidative stress response, xenobiotic metabolism, and PXR/RXR and CAR/RXR activations were predicted to be affected. In conclusion, the liver of rats with NASH induced by Western diet shows a decreased capacity of metabolizing lipids, fatty acids, and xenobiotic compounds that predispose fibrosis development.

RESUMO

Solanum paniculatum L. or popularly known as "jurubeba" is an herbal medicinal plant. A few studies have investigated its biological effects; however, research aimed at elucidating the redox balance effects from its fruits has not been reported so far. ROS interplays in various fields of medicine such as chemotherapy. Here, we evaluated antioxidant and inflammatory activities of the hydroethanolic extract of Solanum Paniculatum L. (HESPL) fruits in breast cancer cells, as well as its phytochemical profile. The antioxidant profile (carotenoids and phenolic compounds) was obtained by HPLC-DAD-UV and HPLC-APCI-MS. Cancer cell lines and human vein endothelial cells (HUVECs) were cultivated and treated with 1.87-30 µg/mL of HESPL for 24 hrs. Cytotoxicity, oxidative, and inflammation biomarkers were evaluated. The dose of 30 µg/mL of the HESPL extract presented cytotoxicity in the MCF-7 cell line. However, for MDA-MB-231, the cytotoxicity was observed in the dose of 1.87 g/mL. The 1.87 µg/mL and 3.75 µg/mL doses decreased the concentration of IL-6 in MCF-7 cells. In the MDA-MB-231 cells, the HESPL did not decrease the IL-6 concentration; however, in the doses of 15 and 30 µg/mL, an increase in this parameter was observed. The HESPL increased IL-1ß concentration in HUVECs. The ROS level in MCF-7 was elevated only at the 30 µg/ml dose. Regarding MDA-MB-231, HESPL promoted increased ROS levels at all doses tested. HUVEC showed no increase in ROS under any dose. HESPL treatment may modulate cytotoxicity, ROS, and cytokine levels due to its phytochemical profile, and it has shown an antioxidant or anti-inflammatory effect.

RESUMO

Health disparities in American Indian/Alaska Native (AI/AN) youth are well documented in the literature, as AI/AN youth appear to be more likely to experience trauma and engage in high-risk behavior, such as substance misuse and risky sexual behavior. These youth also appear disproportionally affected by the criminal justice system. Scholars contend that much of these disparities can be traced back to the history of colonization of Indigenous peoples and the transgenerational effects of forced suppression of cultural ideology. This paper reviews the relevant literature on AI/AN youth mental and behavioral health, and this author highlights studies which examine the plausible relation between historical trauma and contemporary AI/AN youth mental health and delinquency. This author proposes that future research should target the high number of AI/AN youths in juvenile justice settings given that these youths appear neglected in current research.

RESUMO

BACKGROUND: Previous research has examined the relation between mental illness (MI) and perceptions of dangerousness, but less research has focused on its relation to perceived risk of criminality. Individuals with MI are perceived to be more dangerous than those without, and individuals with schizophrenia or substance abuse diagnoses are viewed as being more dangerous. Research also supports that race of individuals with MI plays an important role in the conceptualization and experience of stigma. AIMS: The current study investigated the relation between MI, perceived criminality and race of diagnosed individuals. METHOD: Two hundred ninety participants were randomly assigned to read one of the four vignettes and answer a series of questions. The first three vignettes depicted someone with MI (schizophrenia, depression or alcohol dependency), while the fourth vignette served as a control. Participants were asked to indicate likelihood of committing a future crime, severity of the future crime and the person's potential for rehabilitation. Levels of sympathy and trust, as well as perceived race of the person, were also measured. RESULTS: Presence of MI was a significant predictor where MI elicited higher levels of perceived risk of criminality. The remaining predictor variables (type of MI, familiarity with MI and criminality and perceived race) were not significant predictors. Exploratory analyses revealed the schizophrenia and alcohol dependency conditions elicited higher levels of perceived severity of future crimes. Perceived MI severity and likelihood of rehabilitation were all significantly correlated with perceived risk of criminality. CONCLUSION: Presence of MI appears to be the most important in influencing participant attitudes about perceived risk of criminality, though type of MI may influence beliefs about severity of future crimes. The impact of race could not be examined but should be examined in future studies.

RESUMO

INTRODUCTION: Small cell prostate cancer (SCPC) is a rare histologic subtype of prostate cancer, for which the optimal staging strategy remains unclear. METHOD: The Surveillance, Epidemiology, and End Results database was used to analyze the incidence and outcomes of SCPC between the years 2004 through 2016. Limited-stage SCPC (LS-SCPC) was defined as SCPC without any metastasis regardless of local invasion. Extensive stage SCPC (ES-SCPC) was defined as any metastasis to lymph nodes and/or to distant organs. RESULT: A total of 403 SCPC patients were included in the study cohort, accounting for 0.056% of all prostate cancer cases (n=719,655). Of the 358 patients with known metastasis status, 275 (76.8%) patients had ES-SCPC, whereas 83 (23.2%) patients had LS-SCPC. LS-SCPC was associated with better overall survival (17 vs. 9 mo, P<0.001) and disease-specific survival (25 vs. 10 mo, P<0.001) compared with ES-SCPC. All LS-SCPC patients had a similar overall survival regardless of T stage. Similarly, all ES-SCPC patients had similar outcomes regardless of metastasis sites. High prostate-specific antigen (PSA) is paradoxically associated with superior outcome in both localized stage patients (PSA≥4 vs. PSA<4, 19 vs. 10 mo, P=0.002) and extensive stage patients (PSA≥20 vs. PSA<20, 13 vs. 9 mo, P=0.02). Multivariate analysis of treatment showed that chemotherapy was associated with improved survival in ES-SCPC with hazard ratio of 0.52. CONCLUSION: Similar to small cell lung cancer, SCPC can be staged into LS-SCPC or ES-SCPC. The binary staging system correlates well with prognosis.

RESUMO

Metabolic Syndrome (MetS) is multivariate disease, clustered with socioeconomic and behavioral risk factors. Investigations about epidemiology estimative could be a prevention strategy. AIM: to investigate the prevalence of metabolic syndrome and its associated factors in adult population in Fernando de Noronha Archipelago (PE-Brazil). METHODS: A cross-sectional study was performed on a representative sample (N = 375) of adult residents of the region, aged 24-59 years, were harmonized according to the International Diabetes Federation (IDF) criteria. RESULTS: The prevalence of metabolic syndrome was 45 (12%) and, the age was associated with MetS, which increases the chances to MetS development around 3% respectively (OR: 1.03; CI 95%: 1.002-1.070 P 0.0384). Waist circumference was elevated in female population 266 (70.74%), however, levels of fasting blood glucose (304 [80.85%]), blood pressure (375 [100%]), TG (302 [80.32]), and low HDLc (297 [78.99]) presented normal biochemical values. There is no significative difference for male and female gender and, the social and behavior factors did not present significative association. CONCLUSION: The Fernando de Noronha presents lower prevalence of MetS thus, shows associations for elderly people. The waist circumference was elevated on female population. The results of this study provide further evidence and underscore the need for public health strategies that include education about MetS, promotion of cardiometabolic health, and prevention of undesirable outcomes such as diabetes and cardiovascular disease.
