In this study, we objectively tracked the duration, frequency, and the preferred practices chosen by novice mindfulness practitioners following a mindfulness meditation (MM) intervention. A sample of 55 mildly stressed participants, aged 50 to 80 years old, underwent an individual 6-week MM intervention and had their guided meditation home practice electronically recorded during the intervention and the 8-week post-intervention period. Participants’ psychological well-being was assessed through self-report measures of mindfulness, quality of life, and symptoms of depression and stress. Results evidenced a high adherence to practice, with an average of ~23 minutes per day during the intervention and ~16 minutes per day in the follow-up period. Body scan, sitting meditation, and breathing space were the most popular meditation practices among participants. Our results showed significant alterations in self-reported measures over time, suggesting improvements in stress and overall quality of life. Changes in the self-report measures did not correlate with MM practice time, which suggests that other psychological phenomena, including quality of meditation practice, influence these outcomes.

SummaryToll-like receptors have been implicated in the recognition of various pathogens, including bacteria, viruses, protozoa and fungi. However, no information is available about Toll-like receptor 4 (TLR4) participation in Sporothrix schenckii recognition and the consequent triggering of the immune response to this fungal pathogen. Following activation of TLRs by ligands of microbial origin, several responses are provoked, including reactions in immune cells that may lead them to produce signalling factors that trigger inflammation. The present study was designed to elucidate the role of TLR4 during the host response to S. schenckii. TLR4-deficient (C3H/HeJ) and control mice (C3H/HePas) were infected with S. schenckii yeast cells and immune response was assessed over 10 weeks by assaying production of pro-inflammatory mediator (nitric oxide and tumour necrosis factor-a) and anti-inflammatory cytokine (interleukin-10) by peritoneal macrophages and their correlation with apoptosis in peritoneal exudate cells. We found that both pro-inflammatory and anti-inflammatory mediators are reduced in TLR4-deficient mice, suggesting the involvement of this receptor in the recognition of this infectious agent. Translocation into the nucleus of nuclear transcription factor, nuclear factor-jB, was also evaluated and showed higher levels in TLR-4 normal mice, consistent with the results found for cytokine production. We are showing here, for the first time, the involvement of TLR4 in S. schenckii recognition. Taken together, our results demonstrate that the activation of peritoneal macrophages in response to S. schenckii lipid extracts has different responses in these two mouse strains which differ in TLR4 expression, suggesting an important role for TLR4 in governing the functions of macrophages in this fungal infection.

For many fungal diseases, macrophages are the major cell population implicated in host protection, primarily by their ability to eliminate the invading fungal pathogen through phagocytosis. In sporotrichosis, this remains true, because of macrophages’ ability to recognize Sporothrix schenckii through specific receptors for some of the fungus’ cellular surface constituents. Further confirmation for macrophages’ pivotal role in fungal diseases came with the identification of toll-like receptors, and the subsequent numerous associations found between TLR-4 deficiency and host susceptibility to diverse fungal pathogens. Involvement of TLR-4 in immune response against sporotrichosis has been conducted to investigate how TLR-4 signaling could affect inflammatory response development through evaluation of H2O2 production and IL-1β, IL-6 and TGF-β release during the course of S. schenckii infection on TLR-4-deficient mice. The results showed that macrophages are largely dependent on TLR-4 for inflammatory activation and that in the absence of TLR-4 signaling, increased TGF-β release may be one of the contributing factors for the abrogated inflammatory activation of peritoneal exudate cells during mice sporotrichosis.

BackgroundPolice officers experience a high degree of chronic stress. Policing ranks among the highest professions in terms of disease and accident rates. Mental health is particularly impacted, evidenced by elevated rates of burnout, anxiety and depression, and poorer quality of life than the general public. Mindfulness training has been shown to reduce stress, anxiety, burnout and promote quality of life in a variety of settings, although its efficacy in this context has yet to be systematically evaluated. Therefore, this trial will investigate the efficacy of a mindfulness-based intervention versus a waitlist control in improving quality of life and reducing negative mental health symptoms in police officers.MethodsThis multicenter randomized controlled trial has three assessment points: baseline, post-intervention, and six-month follow-up. Active police officers (n = 160) will be randomized to Mindfulness-Based Health Promotion (MBHP) or waitlist control group at two Brazilian major cities: Porto Alegre and São Paulo. The primary outcomes are burnout symptoms and quality of life. Consistent with the MBHP conceptual model, assessed secondary outcomes include perceived stress, anxiety and depression symptoms, and the potential mechanisms of resilience, mindfulness, decentering, self-compassion, spirituality, and religiosity.DiscussionFindings from this study will inform and guide future research, practice, and policy regarding police offer health and quality of life in Brazil and globally.Trial registrationClinicalTrials.gov NCT03114605.

BackgroundDelays in gross motor development, sensory processing issues, and organic and behavioral problems are known to interfere in the development of feeding skills (FS); and—therefore—in the success of the process of feeding a child. Children with feeding difficulties (FD) commonly present inadequacy of FS.ObjectivesAssessment of five FS in Brazilian children with FD, and search of associations with types of FD.MethodsCross-sectional study with 70 children below 10 years old. Data were obtained from medical records: age, gender, age at texture transitions, feeding phase (breastfeeding, weaning to solids or full solids) at first complaint; characteristics of the meal (duration, environment, and shared meals with adults), self-feeding practices, use of feeding equipment and bottle, mouthing, feeding position and FD diagnosis. Skills were categorized according to standards for age. Chi-Square, Anova Test (or non-parametric equivalent) and Multinomial logistic regression tests were used, with a significance level of 5%.ResultsThere was no difference in FS (p > 0.05) or in the number of FS inadequateness (p = 0.84) according to FD diagnosis. The majority (94%) of children presented at least one delayed development of FS; 1/3 presented delays in more than half of the FS. The most prevalent inadequacies in FS were inadequate feeding position (73.5%), prolonged bottle feeding (56.9%), and inadequate self-feeding practices (37.9%). Feeding complaints first appeared at 10.9 ± 11.4 months, and picky eating was the most prevalent type of FD (37.1%). Most children were fed in inadequate environments (55.2%), without the company of adults (78%). Transition to solid foods occurred at 16 ± 5.6 months. Multinomial logistic regression showed no difference in likelihood of presenting any type of FD compared to picky eating, according to FS. Age at texture transition both from breastfeeding to complementary feeding (p = 0.95), and from complementary feeding to solid foods (p = 0.43) did not vary according to FD diagnosis.ConclusionFS development or number of FS inadequateness did not vary according to FD diagnosis. Identification of these inadequacies could help the discussion for multi-professional treatment of patients with FD.

RESUMOIntrodução: Dirigir é fundamental na sociedade contemporânea, facilitando a mobilidade e a independência das pessoas. Portanto, aqueles com dificuldades em guiar um veículo podem experimentar sensações de limitação, estresse emocional e fracasso. Objetivo: Este estudo visa abordar descritivamente uma amostra de 93 pessoas habilitadas que buscaram por treinamento para motoristas, mas que não conseguiram dirigir após receber a Carteira Nacional de Habilitação. Métodos: Os dados foram coletados em centro de treinamento especializado em pessoas com medo de dirigir. Os participantes preencheram um formulário dicotômico e realizaram uma entrevista objetiva com um psicólogo. Nas duas fases, consideramos respostas autorreferidas dos participantes. Resultados: A maioria da amostra é do sexo feminino (89,2%), com idade entre 21 e 40 anos (59%). Entender as dificuldades no desenvolvimento dessas pessoas como motoristas é difícil, porém a necessidade foi o principal fator para a busca pelo treinamento. O medo de dirigir parece estar associado à falta de prática, sendo as preocupações acerca de causar acidentes, de errar e de perder o controle da situação suas principais manifestações. Conclusão: Muitos dados encontrados neste estudo são compatíveis com os achados da literatura mundial. Porém, percebemos algumas limitações. Mais estudos serão necessários para avaliar o medo de dirigir. ABSTRACTIntroduction: Driving is a fundamental part of living in contemporary society, making easier people´s mobility and independence. For this reason, those who have difficulties to drive can experience feelings of limitation, emotional stress and failure. Objective: The present study aims to analyze descriptively a sample of 93 licensed people that searched for specialized training, but never drove after taken the driver's license.

Tumor sections from nonneoplastic (n = 15), benign (n = 28), and malignant ovarian tumors (n = 20) were obtained from 63 women. Immunohistochemistry of the tumor sections demonstrated that inducible nitric oxide synthase (iNOS) expression was increased in ovarian cancer samples compared to nonneoplastic or benign tumor samples. Using the Griess method, nitric oxide (NO) metabolite levels were also found to be elevated in malignant tumor samples compared to benign tumor samples (P < .05). For stage I ovarian cancer, intracystic NO levels >80 μM were more frequent than NO levels <80 μM, and iNOS expression in well-differentiated carcinomas was greater than in moderately/poorly differentiated carcinomas (P < .05). These data suggest an important role for NO in ovarian carcinogenesis.
