Caffeine induces alveolar bone loss in rats submitted to orthodontic movement via activation of receptor activator of nuclear factor Ò¡B, receptor activator of nuclear factor Ò¡B ligand, and osteoprotegerin pathway.

INTRODUCTION: Caffeine is a widely consumed substance with several effects on bone metabolism. This study aimed to investigate the effect of caffeine on the bone tissue of rats submitted to orthodontic movement. METHODS: Twenty-five male Wistar rats underwent orthodontic movement (21 days) of the first permanent maxillary molars on the left side. The experimental group (caffeine; n = 13) and control group (n = 12) received caffeine and water, respectively, by gavage. Microcomputed tomography was performed to analyze orthodontic movement. Histologic analysis of the inflammatory infiltrate and osteoclast count by tartrate-resistant acid phosphatase were conducted. Maxilla tissue was evaluated for receptor activator of nuclear factor Ò¡B (RANK), RANK ligand (RANKL), and osteoprotegerin by immunohistochemistry. RESULTS: Caffeine exhibited a lower bone volume/tissue volume ratio (78.09% ± 5.83%) than the control (86.84% ± 4.89%; P <0.05). Inflammatory infiltrate was increased in the caffeine group compared with the control group (P <0.05). A higher number of tartrate-resistant acid phosphatase-positive cells was observed in the caffeine (9.67 ± 1.73) than in the control group (2.66 ± 0.76; P <0.01). Immunoexpression of RANK and RANKL in the caffeine group was greater than the control (P <0.05). CONCLUSIONS: The use of caffeine thermogenic induces alveolar bone loss in rats submitted to orthodontic movement via activation of RANK, RANKL, and osteoprotegerin signaling pathways.

Sex- and estrous-related response patterns for alcohol depend critically on the level of compulsion-like challenge.

Alcohol use disorder is a substantial social and economic burden. During the last years, the number of women with drinking problems has been increasing, and one main concern is that they are particularly more vulnerable to negative consequences of alcohol. However, little is known about female-specific response patterns for alcohol, and potential underlying differences in brain mechanisms, including for compulsion-like alcohol drinking (when intake persists despite adverse consequences). We used lickometry to assess behavioral microstructure in adult Wistar male and female rats (n = 28-30) during alcohol-only drinking or moderate- or higher-challenge alcohol compulsion (10 or 60 mg/l quinine in alcohol, respectively). Estrous stages were determined and related to drinking levels and patterns of responding to alcohol, as was ovariectomy. Our findings showed that females (where we didn't determine estrus stage) had similar total licks in a session as males, but significantly longer licking bouts under alcohol-only and moderate-challenge, suggesting greater persistence. Further, greater intake under alcohol-only and moderate-challenge was related to faster licking in males, while female consumption was not related to licking speed. Thus, females could have increased persistence without greater vigor, unlike males. However, under higher-challenge, faster licking did predict higher intake in females, similar to males. To better understand female higher-challenge responding, we examined drinking in relation to phases of the estrous cycle. Higher-challenge had longer bouts only in late diestrus. In addition, ovariectomy led to longer bouts only under higher-challenge, suggesting that conditions with reduced hormone levels could increase female persistence for alcohol under higher-challenge. However, ovariectomy also reduced alcohol-only and moderate-challenge drinking but did not reduce bout length. Thus, intake level and response strategy could be regulated somewhat differently by ovarian hormones. Finally, moderate-challenge licking speed was less variable during early diestrus, and we previously showed more stereotyped responding specifically under moderate-challenge in males. By combining behavioral microstructure and sex- and estrus-related changes in drinking patterns, our results suggest that females have greater persistence for alcohol under lower-challenge drinking, while late diestrus and ovariectomy unmasked greater persistence under higher-challenge. Together, our novel insights could help develop more effective and personalized treatments for problematic alcohol use.

Salicylic Acid and Water Stress: Effects on Morphophysiology and Essential Oil Profile of Eryngium foetidum.

The exogenous application of bioregulators, such as salicylic acid (SA), has exhibited promising outcomes in alleviating drought stress. Nevertheless, its impact on culantro (Eryngium foetidum L.) remains unexplored. Thus, the aim of this study was to assess how SA impacts the growth, morphophysiology, and essential oil composition of culantro when subjected to drought. To achieve this, culantro plants were grown under three different watering regimes: well-watered, drought-stressed, and re-watered. Additionally, they were either treated with SA (100 µM) or left untreated, with water serving as the control. SA application did not mitigate the effects of drought in biomass production but increased biomass, leaf number, leaf area, and photosynthetic pigments under well-irrigated and re-watered conditions. After a drought period followed by re-watering, plants recovered membrane integrity independently of SA application. Water stress and the exogenous application of SA also modulated the profile of essential oils. This is the first report about SA and drought affecting growth and essential oil composition in culantro.

Correlates of cannabis use in a sample of mental health treatment-seeking Canadian armed forces members and veterans.

OBJECTIVE: Canadian Armed Forces (CAF) members and Veterans are more likely to experience mental health (MH) conditions, such as posttraumatic stress disorder (PTSD), than the general Canadian population. Previous research suggests that an increasing number of individuals are employing cannabis for MH symptom relief, despite a lack of robust evidence for its effectiveness in treating PTSD. This research aimed to: (1) describe the prevalence of current cannabis use among MH treatment-seeking CAF members and Veterans; and (2) estimate the association between current cannabis use and a number of sociodemographic, military, and MH-related characteristics. METHOD: Using cross-sectional intake data from 415 CAF members and Veterans attending a specialized outpatient MH clinic in Ontario, Canada, between January 2018 and December 2020, we estimated the proportion of CAF members and Veterans who reported current cannabis use for either medical or recreational purposes. We used multivariable logistic regression to estimate adjusted odds ratios for a number of sociodemographic, military, and MH-related variables and current cannabis use. RESULTS: Almost half of the study participants (n = 187; 45.1%) reported current cannabis use. Respondents who reported current cannabis use for medical purposes had a higher median daily dose than those who reported current cannabis use for recreational purposes. The multivariable logistic regression identified younger age, lower income, potentially hazardous alcohol use, and increased bodily pain as statistically significant correlates of current cannabis use among our MH treatment-seeking sample. PTSD severity, depressive severity, sleep quality, and suicide ideation were not statistically associated with current cannabis use. CONCLUSIONS: Almost half of our treatment-seeking sample reported current cannabis use for medical or recreational purposes, emphasizing the importance of screening MH treatment-seeking military members and Veterans for cannabis use prior to commencing treatment. Future research building upon this study could explore the potential impact of cannabis use on MH outcomes.

Drought stress mitigation by foliar application of L-carnitine and its effect on radish morphophysiology.

Drought is the major abiotic stress limiting crop production worldwide, with drought events being expected to be harsher and more frequent due to the global warming. In this context, the development of strategies to mitigate the deleterious effects of drought, such as the use of biostimulants, is imperative. Radish is a globally cultivated root vegetable, with high nutritional and phytochemical value. Thus, this study aimed to evaluate the potential of exogenous carnitine application in the mitigation of drought stress on radish morphophysiology. For this, radish plants were grown for 30 days, being irrigated with 80% (well-watered) or 15% (drought stress) of water holding capacity and sprayed with carnitine (5, 50, and 500 µM) or water (0 µM-no carnitine). The experimental design was completely randomized, in a 4 × 2 factorial scheme (carnitine concentrations × water conditions) with six replicates, and each experimental unit consisted of one plant. The gas exchanges, chlorophyll a fluorescence, photosynthetic pigments, electrolyte leakage, relative water content, and biomass production and allocation were evaluated. Drought reduced the photosynthetic capacity of plants by impairing water balance and membrane integrity, decreasing biomass accumulation, mainly in globular roots. The application of low carnitine (5 µM) mitigated these negative effects caused by drought, increasing membrane integrity and water balance of plants, while higher carnitine concentration (50 and 500 µM) aggravated drought stress. This study highlights the potential of carnitine in the mitigation of drought stress on radish plants, supporting its role as a biostimulant.

A resiliência psicológica e as práticas de autocuidado relacionadas à promoção da saúde e prevenção de doenças crônicas não transmissíveis em mulheres em atendimento ambulatorial / Psychological resilience and self-care practices related to health promotion and prevention of chronic non-communicable diseases in women in outpatient care

As doenças crônicas não transmissíveis mais prevalentes no mundo são as doenças cardiovasculares, diabetes mellitus, alguns tipos de câncer e doenças respiratórias crônicas. Juntas essas condições foram responsáveis por mais da metade das mortes ocorridas no mundo e no Brasil e constituem o principal problema de saúde. As práticas de autocuidado com a saúde têm sido apontadas como a parte que cabe ao paciente nas estratégias de promoção da saúde. Alguns estudos vêm abordando a resiliência como um importante indicador para a realização de práticas saudáveis de autocuidado, estando associada à autonomia e às habilidades para a autogestão da saúde. O objetivo deste estudo é analisar a associação entre a resiliência psicológica e o autocuidado com a saúde em mulheres adultas. O estudo foi realizado com 159 pacientes dos ambulatórios de ginecologia do Instituto Nacional de Saúde da Mulher, da Criança e do Adolescente Fernandes Figueira, da Fundação Oswaldo Cruz. Foi utilizada a versão brasileira da Escala de Resiliência de Wagnild & Young e um questionário adaptado do Inquérito Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico. O principal resultado foi importância do contexto familiar para os níveis de resiliência, principalmente para mulheres que têm filhos. Não foram encontradas associações significativas entre resiliência e as variáveis de autocuidado. Novas pesquisas deverão ser desenvolvidas para esclarecer as possíveis relação entre resiliência e autocuidado e a importância da informação em saúde para promover mudanças de estilo de vida.

The most prevalent chronic non-communicable diseases in the world are cardiovascular diseases, diabetes mellitus, some types of cancer and chronic respiratory diseases. Together, these conditions were responsible for more than half of the deaths in the world and in Brazil, they constitute the main health problem. Health self-care practices have been identified as the patient's part in health promotion strategies. Some studies have approached resilience as an important indicator for healthy self-care practices, being associated with autonomy and skills for self-management of health. The aim of this study is to analyze the association between psychological resilience and self-care with health in adult women. The study was carried out with 159 patients from the gynecology outpatient clinics of the Fernandes Figueira National Institute of Women's, Children and Adolescents' Health of the Oswaldo Cruz Foundation. The Brazilian version of the Wagnild & Young Resilience Scale and a questionnaire adapted from the Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey were used. The main result was the importance of the family context for resilience levels, especially for women who have children. No significant associations were found between resilience and self-care variables. New research should be developed to clarify the possible relationship between resilience and self-care and the importance of health information to promote lifestyle changes.

Depression, anxiety, suicidal ideation and female climacteric: a narrative review

Climacteric is the period in a woman's life cycle that involves perimenopause, menopause and postmenopause. It represents the end of the reproductive period and the beginning of female aging in the biological sense. Over the past 10 years, an emphasis has been placed on the study of mental health in the female climacteric. Studies about the prevalence of depression, anxiety, suicidal ideation and association with different factors have shown important results on the relevance of these disorders during female climacteric. Considering the importance of these findings in the field of public health and epidemiology, we conducted a narrative review aiming to discuss the current knowledge about the prevalence of depression, anxiety and suicidal ideation in the female climacteric, analyzing methods and results in different studies, selected from a literature review between 2009 and 2019, in the PubMed, Lilacs, Embase, Web of Science and Google Scholar databases. Our results showed that the methodology, cultural and sociodemographic differences, as well as a variety of biopsychosocial factors studied, generate some uncertainties about the exact relationship between depression, anxiety, suicidal ideation and female climacteric. We conclude that more research, greater methodological rigor, more accurate results and a biopsychosocial view are needed and urgent for effective interventions, cost reduction in mental health care, as well as prevention and control of depression, anxiety and suicide in climacteric.

Water immersion and one-year storage influence germination of the pyrenes of Copernicia alba Morong, a palm tree from a neotropical wetland / A imersão em água e o armazenamento de um ano influenciam a germinação dos pirênios de Copernicia alba Morong, uma palmeira de um bioma alagado neotropical

Palm seeds are known for displaying dormancy and a thick endocarp that delays germination and embryo growth; but water treatments may accelerate their germination process. Additionally, ex-situ conservation can cause seed viability loss over time. Data on seed dormancy and storage have been neglected for many native palm species in Brazil. We investigated the effect of water treatments and one-year storage on the germination of Copernicia alba Morong, a palm tree from the Brazilian Pantanal wetland. To address our aim, fresh and stored pyrenes were immersed in water (at room temperature for 24, 48, and 72h) and in hot water (~75°C for 5- and 10-min). Fresh pyrenes germinated up to 84% in control, reaching 100% after water immersion for 48 and 72h. In contrast, one-year storage reduced germination by almost 50%, but water immersion slightly increased the germination of stored pyrenes. On the contrary, hot water decreased germination for both fresh and stored pyrenes. Seeds of C. alba may be classified as orthodox seed storage behavior. Taken all together, water treatments at room temperature improved the germination of the pyrenes. In contrast, long-term seed storage and hot-water treatments may jeopardize germination.

As sementes de palmeiras geralmente apresentam dormência e um endocarpo espesso que retarda a germinação e o crescimento do embrião, contudo, tratamentos com água podem acelerar o processo de germinação das suas sementes. Além disso, a conservação de sementes ex-situ pode causar perda de viabilidade das sementes ao longo do tempo. Dados sobre dormência e armazenamento de sementes têm sido negligenciados para muitas espécies de palmeiras nativas no Brasil. Nós investigamos o efeito da imersão em água e armazenamento de um ano sobre a germinação de sementes de Copernicia alba Morong, uma palmeira do Pantanal brasileiro. Para testar nosso objetivo, pirênios recém-colhidos e armazenados foram imersos em água a temperatura ambiente por 24, 48 e 72h e água quente (~75°C por 5 e 10 min). Pirênios recém coletados germinaram 84% no controle, atingindo 100% após imersão em água por 48 e 72h. Em contraste, o armazenamento de um ano reduziu germinação em ~50%; contudo, a imersão em água promoveu a germinação dos pirênios armazenadas. Por outro lado, a água quente diminuiu a germinação dos pirênios frescos e os armazenados. Sementes de C. alba podem ser classificados em ortodoxas. Em geral,  a imersão em água à temperatura ambiente aumentou a germinação dos pirênios. Entretanto, armazenamento for longa duração e tratamentos com água quente podem prejudicar a germinação.

Potential phytoremediation of Pampa biome native and invasive grass species cohabiting vineyards contaminated with Cu in Southern Brazil.

The objectives were (a) to evaluate whether grasses native to the Pampa biome, Axonopus affinis Chase, Paspalum notatum Flüggé and Paspalum plicatulum Michx, and the invasive grass Cynodon dactylon (L.). Pers have the potential to phytoremediate soil contaminated with Cu (0, 35 and 70 mg Cu kg-1); (b) assess whether the growth of these species is compromised by the excess of Cu available in the soil; and (c) determine the impact of excess Cu on the physiological responses of the studied species. C. dactylon presented the best performance in soil contaminated with 35 mg of Cu kg-1. In C. dactylon, the concentrations of chlorophyll b and carotenoids increased, as did the photosynthetic rate and plant growth. Phytotoxic effects of Cu in soil contaminated with 70 mg of Cu kg-1 were more severe on A. affinis and led to plant death. The other species presented reduced photosynthetic and growth rates, as well as increased activity of antioxidant enzymes such as superoxide dismutase and guaiacol peroxidase. This very same Cu level has decreased photosynthetic pigment concentrations in P. notatum and P. plicatulum. On the other hand, it did not change chlorophyll a and b concentrations in C. dactylon and increased carotenoid concentrations in it. High values recorded for Cu bioaccumulation-in-grass-root factor, mainly in P. plicatulum, have indicated that the investigated plants are potential phytostabilizers. High C. dactylon biomass production-in comparison to other species-compensates for the relatively low metal concentration in its tissues by increasing metal extraction from the soil. This makes C. dactylon more efficient in the phytoremediation process than other species.

Salicylic acid mitigates the effects of mild drought stress on radish (Raphanus sativus) growth.

Water deficit is the most critical factor limiting plant growth and production and salicylic acid (SA) has potential for stress mitigation in plants; therefore, we evaluated the effect of SA on radish (Raphanus sativus L.) growth and ecophysiology under water deficit. Plants were sprayed with SA (100µM) or water (control), and irrigated at 80% (W80), 60% (W60), 40% (W40), and 20% (W20) of field capacity. The SA treatments and drought stress started 7days after sowing and lasted until the end of the cycle (30days after sowing). The morphophysiological analyses showed that radish plants had impaired growth at the lower water supply levels, but the treatment with SA reversed these growth restraints under moderate stress, leading to increases in shoot mass at W40 and storage root mass at W60 and W40. SA treatment also reversed the reduction of storage root volume at W60. The tendency of water deficit to increase F O and reduce F V /F M suggests possible damage to the photosystem II of drought-stressed plants. The parameters of gas exchange and photosynthetic pigments showed maintained photosynthetic efficiency, but total photosynthesis decreased due the lower shoot dry mass. Overall, exogenously applied SA reversed the growth restraints at W60 and W40, which revealed that SA was effective in mitigating the effects of moderate water deficit on biomass accumulation and partitioning in radish plants.

Detection of adenovirus, rotavirus, and hepatitis E virus in meat cuts marketed in Uruguaiana, Rio Grande do Sul, Brazil.

The aim of this study was to investigate the presence of adenovirus (AdV), rotavirus (RV), and hepatitis E virus (HEV) in beef, pork, and chicken meat cuts in retail trade in the city of Uruguaiana, RS, Brazil. A total of 131 meat products were collected (beef, n = 55; chicken, n = 47; pork, n = 29) from 18 commercial establishments (supermarkets, n = 7; butchers, n = 7; markets/grocery stores, n = 4). All samples were evaluated for AdV, RV, and HEV. The genomes of RV and AdV were identified in 29% (n = 38) and 5.34% (n = 7) of the samples, respectively. HEV was not identified in any of the samples. Chicken cuts had a higher frequency of AdV and RV isolates compared to beef and pork (P < 0.05). Among the categories of commercial establishments evaluated, all revealed at least one positive sample for AdV and RV; however, supermarkets showed a higher frequency of RV than others (P < 0.05). The genetic material of AdV and RV was identified simultaneously in 2.29% (n = 3) of samples from supermarkets (n = 2) and grocery stores (n = 1). This is the first report on detection of enteric viruses in meat cuts in the western region of the state of Rio Grande do Sul, Brazil, and the presence of AdV and RV in these products may indicate flaws during the process of handling these foods, especially in places where commercialization provides important public health issues.

Residues of Veterinary Drugs in Animal Products Commercialized in the Border Region of Brazil, Argentina, and Uruguay.

ABSTRACT: The traffic in international animal products can become a public health hazard when legal import sanitary procedures are not followed. In Brazil, due to its extensive border area, the importation of animal products is a common practice in many areas, especially in Rio Grande do Sul, a state that borders Argentina and Uruguay. The objective of this study was to evaluate the presence of veterinary drug residues (antibiotics and antiparasitics) in animal products consumed in Rio Grande do Sul. The presence of residues of veterinary antibiotics and antiparasitics was assessed in 189 meat (beef, pork, and chicken), processed dairy, and meat product samples bought in Argentina (n = 90) and Uruguay (n = 99). Residues of these veterinary drugs were detected in 50 (26.45%) of the samples; 28 samples (14.81%) had antibiotic residues, and 22 samples (11.64%) had antiparasitic residues. Of the 50 positive samples, 40% (15 from Argentina and 5 from Uruguay) had residues above the maximum residue limits (MRLs). Of these 20 samples, 12 had antiparasitic residues above the MRLs (11 beef samples had ivermectin and 1 pork sample had ivermectin and doramectin) and 8 had antibiotic residues above the MRLs (2 pork and 2 sausage samples had doxycycline, 2 cheese samples had doxycycline and chlortetracycline, 1 poultry meat sample had chloramphenicol, and 1 cheese sample had monensin). Because of the potential toxic effects on humans and the potential for pathogens to develop antibiotic resistance, the presence of these residues above the MRLs is a potential risk to public health. The negative impact of consumption of imported animal products can be reduced by implementation of an effective surveillance system and educational campaigns for the general population.

Bilateral sequential theta burst stimulation in depressed veterans with service related posttraumatic stress disorder: a feasibility study.

BACKGROUND: Depression comorbid with posttraumatic stress disorder (PTSD) can be disabling and treatment resistant. Preliminary evidence suggests that repetitive transcranial magnetic stimulation (rTMS), may have a role in helping these patients. There are only few published studies using different rTMS paradigms including bilateral intermittent theta burst (iTBS) and low frequency rTMS. METHODS: In this small cohort observation study, we examined the efficacy of bilateral sequential theta-burst stimulation (bsTBS) in 8 treatment resistant depression (TRD) military veterans with PTSD comorbidity stemming from military service experience. RESULTS: bsTBS was generally well tolerated and resulted in 25% and 38% remission and response rates on Depression scores respectively; 25% remission and response rate on PTSD scores. DISCUSSION: This study demonstrates preliminary feasibility and safety of bsTBS in TRD with comorbid military service related PTSD. We concluded that this paradigm might hold promise as a therapeutic tool to help patients with TRD co-morbid with military service related PTSD. Further adequately powered studies to compare rTMS treatment paradigms in this patient group are warranted.

Food handling in the domestic environment: an online questionnaire study with respondents from 24 of 26 Brazilian states / Manipulação de alimentos no ambiente doméstico: um estudo realizado com emprego de questionário online respondido por habitantes de 24 dos 26 estados brasileiros

Using an online questionnaire, this study evaluated the profile of a Brazilian population's food handling practices in the home environment. The questionnaire, containing questions about domestic behavior in terms of hygiene and food handling, was built and available through social media sites. Information about the participants' profiles, their food pre-preparation, food preparation, and food post-preparation practices, and the occurrence of foodborne diseases (FBDs) was included in the questionnaire. A total of 701 responses were obtained. The interviewees included 78.31% female participants and 21.68% male participants, with an average age of 31.2 years. Nearly all (94.3%) had a complete or incomplete higher education. In the pre-preparation stage, the participants evaluated the shelf life (97.28%) and storage temperature (44.79%) of the products while purchasing them. Regarding food handling practices, only a few participants washed the food packages before storing them (31.95%) or removed hand jewelry or other adornments when washing food (61.48%). Most participants washed their hands (91.58%) and washed vegetables (99.28%). But a group of interviewees reported washing raw meat (27.81%) before preparing it. Cutting surfaces such as plastic (50.36%) and glass (49.36%) tops were the most prevalent in the study. Most respondents did not know how long they had been using their cutting boards (67.62%) and mentioned using the same surface to handle both raw and ready-to-eat products (84.17%). As for the preparation, most interviewees declared they did not check the food temperature during preparation (86.31%), ignoring the ideal cooking temperature (88.26%). Regarding the occurrence of FBDs, 79.17% of the interviewees reported having suspicious clinical signs associated with contaminated foods and 65.59% did not seek medical help. Thus, the participants demonstrated ignorance about adequate practices for food safety in the home environment, highlighting the need to conduct health education programs within the Brazilian population.(AU)

Este estudo teve como objetivo avaliar o perfil das práticas de manipulação de alimentos no ambiente domiciliar no Brasil utilizando um questionário online. Um questionário contendo perguntas sobre comportamento doméstico em nível de higiene e manipulação de alimentos foi construído e disponibilizado por redes sociais. O questionário continha informações sobre o perfil dos participantes, suas práticas de pré-preparo, preparo e pós-preparo de alimentos e a ocorrência de doenças transmitidas por alimentos (DTA). Obteve-se 701 respostas, os entrevistados foram 78,31% do sexo feminino e 21,68% do sexo masculino, com média de idade de 31,2 anos. A maioria (94,3%) possuia ensino superior completo ou incompleto. Na etapa de pré-preparo, os participantes avaliam o prazo de validade (97,28%) e a temperatura de armazenamento (44,79%) dos produtos no momento da compra. Em relação às práticas de manipulação dos alimentos, apenas alguns participantes lavavam as embalagens dos alimentos antes de armazená-los (31,95%) ou retiravam adornos ao lavar os alimentos (61,48%). A maioria dos participantes lavam as mãos (91,58%) e os vegetais (99,28%); entretanto, um grupo de entrevistados relatou lavar carne crua (27,81%) antes de prepará-la. Superfícies de corte como tábuas de plástico (50,36%) e de vidro (49,36%) foram os mais prevalentes no estudo. A maioria dos entrevistados não sabe há quanto tempo usa as tábuas de corte (67,62%) e utilizam a mesma superfície para manusear produtos crus e prontos para o consumo (84,17%). Quanto ao preparo, a maioria dos entrevistados declarou não verificar a temperatura dos alimentos durante o preparo (86,31%), ignorando a temperatura ideal de cozimento (88,26%). Em relação à ocorrência de DVA, 79,17% dos entrevistados relataram que já apresentaram sinais clínicos suspeitos associados a alimentos contaminados e 65,59% não procuraram atendimento médico. Nesse sentido, os participantes demonstraram desconhecimento sobre as práticas adequadas para a segurança dos alimentos no ambiente domiciliar, evidenciando a necessidade de realização de programas de educação em saúde com a população brasileira.(AU)

Well-being of Canadian Veterans during the COVID-19 pandemic: cross-sectional results from the COVID-19 Veteran well-being study.

Background: The impacts of the COVID-19 pandemic have disproportionally affected different population groups. Veterans are more likely to have pre-existing mental health conditions compared to the general Canadian population, experience compounded stressors resulting from disruptions to familial, social, and occupational domains, and were faced with changes in health-care delivery (e.g. telehealth). The objectives of this study are to assess (a) the mental health impact of COVID-19 and related life changes on the well-being of Veterans and (b) perceptions of and satisfaction with changes in health-care treatments and delivery during the pandemic. Methods: A total of 1136 Canadian Veterans participated in an online survey. Participants completed questions pertaining to their mental health and well-being, lifestyle changes, and concerns relating to the COVID-19 pandemic, as well as experiences and satisfaction with health-care treatments during the pandemic. Results: Results showed that 55.9% of respondents reported worse mental health functioning compared to before the pandemic. The frequency of probable posttraumatic stress disorder, major depressive disorder, generalized anxiety disorder, alcohol use disorder, and suicidal ideation were 34.2%, 35.3%, 26.8%, 13.0%, and 22.0%, respectively. Between 38.6% and 53.1% of respondents attributed their symptoms as either directly related to or exacerbated by the pandemic. Approximately 18% of respondents reported using telehealth for mental health services during the pandemic, and among those, 72.8% indicated a choice to use telehealth even after the pandemic. Conclusions: This study found that Veterans experienced worsening mental health as a result of the COVID-19 pandemic. The use of telehealth services was widely endorsed by mental health treatment-seeking Veterans who transitioned to virtual care during the pandemic. Our findings have important clinical and programmeadministrator implications, emphasizing the need to reach out to support veterans, especially those with pre-existing mental health conditions and to enhance and maintain virtual care even post-pandemic.

Antecedentes: Los impactos de la pandemia del COVID-19 han afectado de manera desproporcionada a diferentes grupos de la población. Los veteranos tienen más probabilidades de tener afecciones de salud mental preexistentes en comparación con la población canadiense en general, experimentar factores estresantes agravados como resultado de las interrupciones en los dominios familiares, sociales, y ocupacionales, y se enfrentan a cambios en la prestación de la atención médica (por ejemplo, telesalud). Los objetivos de este estudio son evaluar (a) el impacto en la salud mental del COVID-19 y los cambios de vida relacionados en el bienestar de los Veteranos y (b) las percepciones y la satisfacción con los cambios en los tratamientos y la entrega de la atención médica durante la pandemia.Métodos: Un total de 1136 veteranos canadienses participaron en una encuesta en línea. Los participantes completaron preguntas relacionadas con su salud mental y bienestar, cambios en el estilo de vida, e inquietudes relacionadas con la pandemia del COVID-19, así como experiencias y satisfacción con los tratamientos de atención médica durante la pandemia.Resultados: Los resultados mostraron que el 55,9% de los encuestados informaron un peor funcionamiento de la salud mental en comparación con antes de la pandemia. La frecuencia de probable trastorno de estrés postraumático, trastorno depresivo mayor, trastorno de ansiedad generalizada, trastorno por consumo de alcohol, e ideación suicida fue del 34,2%, 35,3%, 26,8%, 13,0% y 22,0%, respectivamente. Entre el 38,6% y el 53,1% de los encuestados atribuyeron sus síntomas como directamente relacionados con la pandemia o agravados por ella. Aproximadamente el 18% de los encuestados informó haber utilizado la telesalud para los servicios de salud mental durante la pandemia, y entre ellos, el 72,8% indicó que había optado por utilizar la telesalud incluso después de la pandemia.Conclusiones: Este estudio encontró que los Veteranos experimentaron un empeoramiento de la salud mental como resultado de la pandemia del COVID-19. El uso de los servicios de telesalud fue ampliamente respaldado por los Veteranos en busca de tratamiento de salud mental que hicieron la transición a la atención virtual durante la pandemia. Nuestros hallazgos tienen importantes implicaciones clínicas y para los administradores de programas, enfatizando la necesidad de ayudar a los veteranos, especialmente a aquellos con condiciones de salud mental preexistentes, y de mejorar y mantener la atención virtual incluso después de una pandemia.

Well-being of Canadian Armed Forces Veterans and Spouses of Veterans During the COVID-19 Pandemic: Protocol for a Prospective Longitudinal Survey.

BACKGROUND: The COVID-19 pandemic has resulted in significant changes to everyday life, including social distancing mandates, changes to health care, and a heightened risk of infection. Previous research has shown that Canadian Armed Forces (CAF) veterans are at higher risk of developing mental and physical health conditions. Veterans and their families may face unique social challenges that can compound with pandemic-related disruptions to negatively impact well-being. OBJECTIVE: This study aims to longitudinally characterize the mental health of CAF veterans and spouses of CAF veterans throughout the pandemic and to understand the dynamic influences of pandemic-related stressors on psychological health over time. METHODS: We employed a prospective longitudinal panel design using an online data collection platform. Study participation was open to all CAF veterans and spouses of CAF veterans residing in Canada. Participants were asked to complete a comprehensive battery of assessments representing psychological well-being, chronic pain, health care access patterns, physical environment, employment, social integration, and adjustment to pandemic-related lifestyle changes. Follow-up assessments were conducted every 3 months over an 18-month period. This study was approved by the Western University Health Sciences and Lawson Health Research Institute Research Ethics Boards. RESULTS: Baseline data were collected between July 2020 and February 2021. There were 3 population segments that participated in the study: 1047 veterans, 366 spouses of veterans, and 125 veterans who are also spouses of veterans completed baseline data collection. As of November 2021, data collection is ongoing, with participants completing the 9- or 12-month follow-up surveys depending on their date of self-enrollment. Data collection across all time points will be complete in September 2022. CONCLUSIONS: This longitudinal survey is unique in its comprehensive assessment of domains relevant to veterans and spouses of veterans during the COVID-19 pandemic, ranging from occupational, demographic, social, mental, and physical domains, to perceptions and experiences with health care treatments and access. The results of this study will be used to inform policy for veteran and veteran family support, and to best prepare for similar emergencies should they occur in the future.

Contribuições teóricas para uma demografia dos desastres no Brasil / Theoretical contributions for a demography of disasters in Brazil / Contribuciones teóricas para una Demografía de los desastres en Brasil

Resumo As mudanças demográficas associadas à complexidade dos problemas ambientais contemporâneos, como as mudanças ambientais globais e os desastres tecnológicos, tornarão cada vez mais perene a (re)produção social dos riscos e desastres a eles associados. O artigo propõe reflexões que posicionem a demografia, particularmente no contexto brasileiro, de forma a incorporar esses desafios aos seus conceitos, teorias e metodologias de análise, consolidando o campo de estudos em demografia dos desastres. O percurso escolhido foi, inicialmente, o de revisitar conceitos presentes em estudos de população e ambiente, como riscos, danos, desastres, vulnerabilidade, adaptação e resiliência. Revisitamos a literatura produzida em demografia dos desastres, enfatizando a relação endógena entre desastres e a composição, distribuição e dinâmica demográfica. Em seguida, propusemos um marco teórico sobre demografia dos desastres, bem como sua operacionalização a partir de sete princípios. Por fim, discutimos como, tanto do ponto vista conceitual, teórico quanto metodológico, a demografia possui um papel fundamental para consolidar uma perspectiva científica que antagonize discursos de "naturalização" dos desastres e, consequentemente, contribua para criar ou aperfeiçoar políticas públicas e mecanismos de gestão e planejamento antes, durante e após os desastres.

Abstract Demographic changes, associated with the complexity of contemporary environmental problems such as global environmental changes and technological disasters, will make the social (re)production of risks and associated disasters increasingly permanent. The article proposes reflections that position Demography, particularly in the Brazilian context, in order to incorporate these challenges into its concepts, theories, analyses and methodologies, consolidating the field of knowledge in Demography of Disasters. The strategy initially chosen was to revisit concepts in population and environment studies, such as risks, damages, disasters, vulnerability, adaptation and resilience. We reviewed the literature produced on Demography of Disasters, emphasizing the endogenous relationship between disasters and demographic composition, distribution and dynamics. Then, we proposed a theoretical framework on Demography of Disasters, and its operationalization in seven principles. Finally, we discuss how, both from a conceptual and theoretical point of view, as well as from a methodological standpoint, demography plays a fundamental role in consolidating a scientific perspective that antagonizes discourses of "naturalization" of disasters and, consequently, contributes to creating or improving public policies and management and planning before, during and after disasters.

Impacts of morally distressing experiences on the mental health of Canadian health care workers during the COVID-19 pandemic.

Background: Research is urgently needed to understand health care workers' (HCWs') experiences of moral-ethical dilemmas encountered throughout the COVID-19 pandemic, and their associations with organizational perceptions and personal well-being. This research is important to prevent long-term moral and psychological distress and to ensure that workers can optimally provide health services. Objective: Evaluate associations between workplace experiences during COVID-19, moral distress, and the psychological well-being of Canadian HCWs. Method: A total of 1362 French- and English-speaking Canadian HCWs employed during the COVID-19 pandemic were recruited to participate in an online survey. Participants completed measures reflecting moral distress, perceptions of organizational response to the pandemic, burnout, and symptoms of psychological disorders, including depression, anxiety, and posttraumatic stress disorder (PTSD). Results: Structural equation modelling showed that when organizational predictors were considered together, resource adequacy, positive work life impact, and ethical work environment negatively predicted severity of moral distress, whereas COVID-19 risk perception positively predicted severity of moral distress. Moral distress also significantly and positively predicted symptoms of depression, anxiety, PTSD, and burnout. Conclusions: Our findings highlight an urgent need for HCW organizations to implement strategies designed to prevent long-term moral and psychological distress within the workplace. Ensuring availability of adequate resources, reducing HCW risk of contracting COVID-19, providing organizational support regarding individual priorities, and upholding ethical considerations are crucial to reducing severity of moral distress in HCWs.

Antecedentes: Se necesita con urgencia investigaciones para comprender las experiencias de los dilemas éticos y morales que los trabajadores de la salud encontraron durante la pandemia de la COVID-19 y su asociación con las percepciones de la organización y el bienestar personal. Esta investigación es importante para prevenir la angustia moral y psicológica a largo plazo y para asegurar que los trabajadores de la salud puedan proveer de manera óptima los servicios de salud.Objetivo: Evaluar la asociación entre las experiencias en el lugar de trabajo durante la COVID-19, la angustia moral y el bienestar psicológico de los trabajadores de salud canadienses.Métodos: Se reclutó a un total de 1362 trabajadores de salud canadienses, que hablaban francés e inglés y que fueron contratados durante la pandemia de la COVID-19, para participar en un cuestionario en línea. Los participantes completaron mediciones que reflejaban la angustia moral, la percepción de la respuesta de la organización a la pandemia, el burnout y los síntomas de trastornos psicológicos, que incluían a la depresión, a la ansiedad y al trastorno de estrés postraumático (TEPT).Resultados: El modelo de ecuaciones estructurales mostró que cuando los predictores de la organización se consideraban en conjunto ­ los recursos adecuados, el impacto positivo en la vida laboral y un ambiente de trabajo ético ­, predijeron negativamente la gravedad de la angustia moral, mientras que la percepción del riesgo de contraer la COVID-19 predijo positivamente la gravedad de la angustia moral. La angustia moral también predijo de manera significativa y positiva los síntomas de la depresión, la ansiedad, el TEPT y el burnout.Conclusiones: Nuestros hallazgos resaltan la urgente necesidad de que las organizaciones de trabajadores de salud implementen estrategias diseñadas para prevenir la angustia moral y psicológica a largo plazo en el lugar de trabajo. El asegurar la disponibilidad de los recursos adecuados, el reducir el riesgo de que los trabajadores de salud contraigan la COVID-19, el proveer un soporte organizacional adecuado según las prioridades individuales y el respetar las consideraciones éticas son fundamentales para reducir la gravedad de la angustia moral en los trabajadores de salud.

Exploring the Well-being of Health Care Workers During the COVID-19 Pandemic: Protocol for a Prospective Longitudinal Study.

BACKGROUND: Health care workers (HCWs) have experienced several stressors associated with the COVID-19 pandemic. Structural stressors, including extended work hours, redeployment, and changes in organizational mandates, often intersect with interpersonal and personal stressors, such as caring for those with COVID-19 infections; worrying about infection of self, family, and loved ones; working despite shortages of personal protective equipment; and encountering various difficult moral-ethical dilemmas. OBJECTIVE: The paper describes the protocol for a longitudinal study seeking to capture the unique experiences, challenges, and changes faced by HCWs during the COVID-19 pandemic. The study seeks to explore the impact of COVID-19 on the mental well-being of HCWs with a particular focus on moral distress, perceptions of and satisfaction with delivery of care, and how changes in work structure are tolerated among HCWs providing clinical services. METHODS: A prospective longitudinal design is employed to assess HCWs' experiences across domains of mental health (depression, anxiety, posttraumatic stress, and well-being), moral distress and moral reasoning, work-related changes and telehealth, organizational responses to COVID-19 concerns, and experiences with COVID-19 infections to self and to others. We recruited HCWs from across Canada through convenience snowball sampling to participate in either a short-form or long-form web-based survey at baseline. Respondents to the baseline survey are invited to complete a follow-up survey every 3 months, for a total of 18 months. RESULTS: A total of 1926 participants completed baseline surveys between June 26 and December 31, 2020, and 1859 participants provided their emails to contact them to participate in follow-up surveys. As of July 2021, data collection is ongoing, with participants nearing the 6- or 9-month follow-up periods depending on their initial time of self-enrollment. CONCLUSIONS: This protocol describes a study that will provide unique insights into the immediate and longitudinal impact of the COVID-19 pandemic on the dimensions of mental health, moral distress, health care delivery, and workplace environment of HCWs. The feasibility and acceptability of implementing a short-form and long-form survey on participant engagement and data retention will also be discussed.

First Report of Colletotrichum chrysophilum Causing Anthracnose on Blueberry in Brazil.

Highbush (Vaccinium corymbosum L.) and rabbiteye (V. ashei R.) blueberry are the most important export small fruit crops in southern Brazil. Anthracnose has been considered one of the most destructive disease and exclusively associated with C. karstii in Brazil (Rios et al. 2014). In November 2019, severe anthracnose symptoms including leaf spots but particularly twig blights and fruit rots were observed on all blueberry plants (V. ashei) in one organic orchard in Santa Catarina state, Brazil (27º43'48.96"S, 49º0'57.79"W). Four isolates were obtained from necrotic lesions and monosporic cultures were grown on potato dextrose agar at 25°C and with a 12 h photoperiod under near ultra violet light. After 15 days, colonies showed upper surface color varying from grayish-white to pale-orange and the reverse side pale-orange. Conidia were hyaline, cylindrical with rounded ends, and their length and width ranged from 9.5 to 15.5 µm (x ̅=11.8) and 6.5 to 3.5 µm (x ̅=4.9), respectively. The isolates were identified by multilocus phylogenetic analyses using nucleotide sequences of actin (ACT), ß-tubulin (TUB2), calmodulin (CAL), glyceraldehyde-3-phosphate-dehydrogenase (GAPDH), glutamine synthetase (GS), internal transcribed spacer (ITS) and the intergenic spacer between DNA lyase and the mating-type locus MAT1-2-1 (ApMAT). Nucleotide sequences exhibited from 95 to 100% sequence identity to Colletotrichum chrysophilum ex-type (CMM4268) and were deposited in GenBank database (MW868219 to MW868222, MW868211 to MW868214, MW868215 to MW868218, MW868223 to MW868226, MW868202 to MW868205, MW793353 to MW793356, and MW868207 to MW868210). C. chrysophilum belongs to the C. gloeosporioides species complex and was previously described as C. ignotum in banana and other tropical fruits in Brazil (Vieira et al. 2017; Veloso et al. 2018). In addition, this species was recently reported on apple fruit in New York, USA (Khodadadi et al. 2020). To confirm pathogenicity, one-year-old blueberry plants were inoculated by spraying a suspension of 1×106 conidia/ml, incubated in a moist chamber in the dark for 48 h and then kept in the greenhouse. Plants sprayed with sterile distilled water served as control. Additionally, fruits were immersed for 2 min in a conidial suspension (1×106 conidia/ml) and incubated at 25°C and 12 h photoperiod for 20 days. Inoculated plants exhibited first symptoms in twigs at 10 days after inoculation (dai). Infected twigs showed initially dark brown spots that coalesced and became necrotic. On leaves, reddish-brown lesions with less than 2 mm appeared at low intensity at 15 dai. On fruits, sunken areas associated with an abundant orange mucilaginous mass of acervuli and conidia were seen at 7 dai. Symptoms on plants were identical to those observed under field conditions, and the pathogen was re-isolated from lesions fulfilling Koch's postulates. To the best knowledge, this is the first report of C. chrysophilum causing anthracnose on blueberries in Brazil. The identification of this species causing blueberry anthracnose is crucial to improve the disease control strategies and resistance breeding.
