Paracoccidioides lutzii Infects Galleria mellonella Employing Formamidase as a Virulence Factor.

The formamidase (FMD) enzyme plays an important role in fungal thriving by releasing a secondary nitrogen source as a product of its activity. In Paracoccidioides species, previous studies have demonstrated the upregulation of this enzyme in a wide range of starvation and infective-like conditions. However, Paracoccidioides lutzii formamidase has not yet been defined as a virulence factor. Here, by employing in vivo infections using an fmd-silenced strain in Galleria mellonella larvae model, we demonstrate the influence of formamidase in P. lutzii's immune stimulation and pathogenicity. The formamidase silencing resulted in improper arrangement of the nodules, poor melanogenesis and decreased fungal burden. Thus, we suggest that formamidase may be a piece composing the process of molecular recognition by Galleria immune cells. Furthermore, formamidase silencing doubled the observed survival rate of the larvae, demonstrating its importance in fungal virulence in vivo. Therefore, our findings indicate that formamidase contributes to Galleria's immune incitement and establishes the role of this enzyme as a P. lutzii virulence factor.

Profile and satisfaction of patients with special health care needs assisted in dental specialty centers.

This study aimed to analyze the profile and level of satisfaction of users served in the dental specialty for patients with special healthcare needs (SHCN), based on the Brazilian Program for Improving Access and Quality ("PMAQ") of the Centers for Dental Specialties ("CEO"). This observational, quantitative study used a national secondary database in the public domain. Data were analyzed using the chi-squared test with Bonferroni correction, Student's t-test, and log-linear Poisson regression. Most users of the specialty "SHCN" interviewed were female (74.1% in 2014 and 68.8% in 2018), with a mean age of 41.7 (2014) and 44.9 (2018) years. For every 100 respondents who considered it regular or bad, 171 considered it good, and 199 considered it very good. Regarding satisfaction with the host of the "CEO," there were differences between the regions of Brazil (Midwest, Northeast, Southeast, and South). There has been an increase in the number of "CEO" that serve users with autism spectrum disorder. Generally, the "CEO" network provides humanized and welcoming services, presenting better performance in the second evaluation cycle, according to user perception.

The use of digital platforms and physical activity practice in a population from southern Brazil: Findings from the PAMPA Cohort.

Objective: We aimed to identify the factors associated with using digital platforms for physical activity during the COVID-19 pandemic among adults living in Southern Brazil. We also compared the trajectory of physical activity between users and non-users and by type of digital platform used. Methods: We analyzed data from the PAMPA (Prospective Study About Mental and Physical Health in Adults) cohort. The study started in June 2020, and tracked participants through three waves (December 2020, June 2021, and June 2022). The exposure variable was usingf digital platforms for physical activity. The outcome measure was minutes per week of physical activity. We employed a generalized linear model with robust variance to explore the interaction between time and the use of digital platforms, adjusting for sociodemographic covariates and the presence of chronic diseases. Results: The proportion of participants using digital platforms for physical activity declined from 36.8% in 2020 to 25.6% in 2021 and further to 13.5% in 2022. Using digital platforms for physical activity was associated with a higher mean daily physical activity during the COVID-19 pandemic. Participants who used digital platforms were more likely to be physically active when compared to their inactive contemparts throughout the entire study period. Notably, social media emerged with greater influence in the physical activity practice among digital platforms. Conclusion: Using these platforms had a positive impact on increasing the level of physical activity among the participants.

Influences in food selection during complementary feeding in breastfeeding infants: A systematic review and metasynthesis of qualitative studies.

In the transition period from breastfeeding to the introduction of complementary feeding, the choice of food is extremely important for the child's development as many factors may be related. This study aims to investigate, through a systematic review and qualitative meta-synthesis, influence in the selection of foods in the introduction of complementary foods for children, including qualitative studies without language or publication period restrictions. Searches were performed in PubMed, LILACS, SciELO, Cinahl, Embase, Web of Science, and Scopus. Initially, 12,489 articles were selected for tittle reading, 13 were included in the review. Four analytical themes related to factors influencing complementary feeding were identified: family socioeconomic conditions, cultural and family aspects, guidance and advice from health professionals, and factors inherent to the infant. Economic factors, such as the opportunity to offer foods not consumed during the parents' childhood, were emphasized. The influence of grandmothers' opinions and community beliefs and traditions were considered. Trust in pediatricians and community health agents' advice, although considered, conflicted with cultural and family traditions. Mothers/caregivers often preferred to offer foods the child shows preference for, rather than introducing new flavors. The findings underscore the need for a better understanding of qualitative aspects.

Análise de perfil de saúde dos trabalhadores de um hospital do sul do Brasil / Health profile analysis of hospital workers in southern Brazil / Análisis del perfil de salud de los trabajadores de un hospital del sur de Brasil

A análise do perfil de saúde dos profissionais de saúde é necessária em ambientes hospitalares devido ao nível de insalubridade apresentado nesses locais. Assim, o objetivo deste estudo foi investigar o perfil de saúde, nível de atividade física e exposição a telas de trabalhadores de um hospital no Sul do Brasil. Este estudo tem caráter transversal e descritivo, e a amostra utilizada foi composta por trabalhadores adultos de um hospital universitário do Sul do Brasil. Os resultados indicaram que a maioria eram mulheres, brancas, de 35-44 anos, com especialização, renda de três a seis salários mínimos, percepção de bem-estar "boa" a "regular", índice de massa corporal "eutrófico" a "sobrepeso", sem doenças crônicas, não fumantes, com sono irregular, ansiedade em níveis normais, saúde percebida como "boa", sedentários, com mais de seis horas de tempo sentado em dias de trabalho. Foram encontradas associações entre ansiedade e várias variáveis. Embora com aspectos positivos, destaca-se que os trabalhadores apresentaram fatores de riscos à saúde, como sedentarismo, tempo prolongado sentado e dor corporal leve e sono irregular. Intervenções em saúde como diminuição de sedentarismo promovendo a prática de atividade física, redução de tempo sentado e orientações para manejo do sono e alívio de dores são necessárias nesse ambiente.

Analyzing the health profile of healthcare professionals is necessary in hospital environments due to their level of unhealthy conditions. Thus, this study investigated the health profile, level of physical activity, and screen exposure of workers at a hospital in southern Brazil. A cross-sectional descriptive was conducted with adult workers from a university hospital in southern Brazil. Results indicated that most participants were white women aged 35 to 44 years with specialization, an income of three to six minimum wages, well-being perceived as "good" to "regular", "eutrophic" to "overweight" body mass index, without chronic diseases, non-smokers, with irregular sleep, anxiety at normal levels, health perceived as "good," sedentary, sitting for more than six hours on work days. Associations were found between anxiety and several variables. Despite positive aspects, workers presented health risk factors such as a sedentary lifestyle, prolonged sitting, mild body pain, and irregular sleep. Health interventions to reduce sedentary lifestyles by promoting physical activity, to reduce sitting time, and to guide sleep management and pain relief are necessary in this setting.

Association between food insecurity and long COVID in adults from southern Brazil: findings of the PAMPA cohort.

BACKGROUND: Social and economic factors, such as food insecurity, contribute to long coronavirus disease (COVID). During the pandemic, a significant rise in food insecurity was observed, both in Brazil and worldwide. We aimed to investigate the association between food insecurity and long COVID in Brazilian adults. METHODS: Cross-sectional study nested within the Prospective study About Mental and Physical Health in Adults (PAMPA) Cohort. Participants completed an online questionnaire in June 2022. We assessed food insecurity using the Brazilian Scale of Food Insecurity. Long COVID was defined as any post-coronavirus disease 2019 symptoms that persisted for at least 3 months after infection. RESULTS: A total of 956 participants were included (74.0% female, median age 36 (Interquartile Range [IQR] (29-45.7). The prevalence of food insecurity was 29.4%, and 77.8% had long COVID. Food insecurity was associated with an increased probability of long COVID (prevalence ratio [PR]: 1.15, 95% confidence interval [CI]: 1.08-1.22). Participants in food insecurity situations had a higher likelihood of experiencing neurological (PR: 1.19, 95% CI: 1.10-1.28), pulmonary (PR: 1.33, 95% CI: 1.17-1.52) and gastrointestinal (PR: 1.57, 95% CI: 1.31-1.88) symptoms after infection. CONCLUSIONS: Food insecurity was associated with long COVID. Governments must plan public policies to mitigate the effects of long COVID and food insecurity.

Longitudinal impact of leisure-time physical activity on pain intensity and daily activity limitation in people with low back pain. Findings from the PAMPA cohort.

OBJECTIVE: We aimed to prospectively evaluate the association between leisure-time physical activity and outcomes related to low back pain (LBP), such as pain intensity and daily activity limitation. METHODS: We analyzed data from the PAMPA (Prospective Study about Mental and Physical Health) cohort, a longitudinal study with adults residing in Southern Brazil. Participants answered an online-based, self-administered questionnaire. Physical activity was assessed as minutes per week, and those who reported engaging in 150 min/week or more were considered active. We also assessed the types of activities participants engaged. Pain intensity was assessed with a numeric pain rating scale (from 0 to 10), and participants reported whether their pain restricted their daily activities. Generalized linear models were used to investigate the association between physical activity and LBP outcomes. RESULTS: Data from 991 individuals (82.7% women) aged 38.9 ± 13.9 were analyzed. Pain intensity was higher in those inactive in waves one (ß: 0.54; 95 % CI 0.23, 0.86), three (ß: 0.38; 95% CI 0.02, 0.75), and four (ß: 0.48; 95% CI 0.06, 0.90). Also, being physically inactive at wave one was associated with a higher probability of daily activity limitation at waves two (IRR 1.77; 95% CI 1.27; 2.46), three (IRR 1.63; 95% CI 1.17, 2.29), and four (IRR 1.73; 95% CI 1.20, 2.50). CONCLUSION: Not practicing at least 150 min/week of physical activity resulted in higher levels of pain and an increased risk of daily activity limitation in individuals with LBP. Moreover, various forms of activities have shown to be advantageous in alleviating pain among this group.

Cutting-edge issues in sympathetic ophthalmia approach and six case reports: a T cell-mediated autoimmune response.

Sympathetic ophthalmia is a rare and potentially devastating bilateral diffuse granulomatous panuveitis. It is caused by surgical or non-surgical eye injuries and is an uncommon and serious complication of trauma. It is diagnosed clinically and supported by imaging examinations such as ocular ultrasonography and optical coherence tomography. Its treatment consists of immunosuppressive therapy with steroids and sometimes steroid-sparing drugs, such as cyclosporine, azathioprine, cyclophosphamide, and mycophenolate mofetil. Fast and effective management with systemic immunosuppressive agents allows for disease control and achievement of good visual acuity in the sympathizing eye. By contrast, enucleation should be considered only in situations where the injured eye has no light perception or in the presence of severe trauma. In addition to a bibliographic review of this topic, we report six cases involving different immunosuppressive and surgical treatment modalities.

Exercise as medicine! Physical activity mitigated the impact of the COVID-19 pandemic on depressive symptoms in adults with depression.

We investigated the longitudinal association between physical activity (PA) and symptoms of depression and anxiety in people with depression during the COVID-19 pandemic. We used data from baseline (June 2020) to wave 3 (June 2021) of the PAMPA Cohort, an ambispective cohort with adults in south Brazil. The Hospital Anxiety and Depression Scale assessed depressive and anxiety symptoms in all waves. Participants reported frequency (minutes), type (aerobic, strength, combined), and place (out of home, at home) of physical activity at baseline. Generalized linear models were used to investigate the interaction between time and PA, adjusting for possible confounding variables. Subjective memory decline was assessed using multivariate Cox proportional hazard regression models to obtain adjusted hazard ratio (HR) and respective 95% confidence interval (CI). Participants (n = 424) with self-reported clinically diagnosed depression were included. We observed a non-linear increase trajectory of depression during the first year of the COVID-19 pandemic. PA was associated with a slower trajectory of depressive (slope: -1.89; 95%CI: -3.34, -0.43 points) but not anxiety (slope: -1.33; 95%CI: -2.93, 0.25 points) symptoms during the COVID-19 pandemic. Participants who continued physically active from pre-pandemic in wave 1 showed a lower risk of subjective memory decline during follow-up than those who persisted inactive in the same period (HR: 0.52; 95%CI: 0.30, 0.89). PA attenuated the impact of the COVID-19 pandemic on depressive symptoms in adults living with depression in south Brazil. Regularity of physical activity was associated with fewer depression and anxiety symptoms and a lower risk of subjective memory decline.

Anticonvulsant activity of Tetrahydrolinalool: behavioral, electrophysiological, and molecular docking approaches.

Tetrahydrolinalool (THL) is an acyclic monoterpene alcohol, produced during linalol metabolism and also a constituent of essential oils. As described in the literature, many monoterpenes present anticonvulsant properties, and thus we became interested in evaluating the anticonvulsant activity of Tetrahydrolinalool using in mice model as well as in silico approaches. Our results demonstrated that THL increased latency to seizure onset and also reduced the mortality, in picrotoxin induced seizure tests. The results may be related to GABAergic regulation, which was also suggested in seizure testing induced by 3-mercapto-propionic acid. In the strychnine-induced seizure testing, none of the groups pretreated with THL modulated the parameters indicative of anticonvulsant effect. The electrophysiological results revealed that THL treatment reduces seizures induced by pentylenetetrazole. The in silico molecular docking studies showed that the interaction between THL and a GABAA receptor model formed a stable complex, in comparison to the crystaligraphic structure of diazepam, a structurally related ligand. In conclusion, all the evidences showed that THL presents effective anticonvulsant activity related to the GABAergic pathway, being a candidate for treatment of epileptic syndromes.
