A review on the diversity and distribution of athecate dinoflagellates in South Atlantic and in the Atlantic sector of the Southern Ocean: Research insights and gaps.

This review summarizes the state of knowledge on athecate dinoflagellates occurring within the South Atlantic Ocean and Atlantic sector of the Southern Ocean. We compiled data from 105 articles and selected 33 addressing any aspect of athecate dinoflagellate studies. Our aim is to discuss the patterns in athecate dinoflagellate distribution by building a thorough species list and an occurrence map based on species recorded in coastal and oceanic waters. We found 69 species totaling 141 occurrences in the entire South Atlantic Ocean basin. Contradicting global trends, most species distributed throughout this region are subtropical. We linked this trend to a higher local effort in dinoflagellate research instead of higher biodiversity, especially when compared to usual hotspots in biodiversity attributed to tropical oceans. The Subantarctic and Antarctic regions had a low number of occurrences, with 12 and 5, respectively. Except for the occurrence of Gyrodinium lachryma in the Antarctic Zone, all records are unique, poorly described and never recorded again for species such as Gymnodinium baccatum and Gymnodinium antarcticum. This demonstrates that the state of knowledge regarding athecate dinoflagellates in the South Atlantic and especially in the Antarctic region is still limited due to a lack of directed investigation.

Real-world approaches to outpatient treatment of status migrainosus: A survey study.

OBJECTIVES: Identify how the American Headache Society (AHS) membership manages status migrainosus (SM) among outpatients. BACKGROUND: SM is defined as a debilitating migraine attack lasting more than 72 h. There is no standard of care for SM, including whether a 72-h duration is required before the attack can be treated as SM. METHODS: The Refractory Headache Special Interest Group from AHS developed a four-question survey distributed to AHS members enquiring (1) whether they treat severe refractory migraine attacks the same as SM regardless of duration, (2) what their first step in SM management is, (3) what the top three medications they use for SM are, and (4) whether they are United Council for Neurologic Subspecialties (UCNS) certified. The survey was conducted in January 2022. Descriptive statistical analyses were performed. RESULTS: Responses were received from 196 of 1859 (10.5%) AHS members; 64.3% were UCNS certified in headache management. Respondents treated 69.4% (136/196) of patients with a severe refractory migraine attack as SM before the 72-h period had elapsed. Most (76.0%, 149/196) chose "treat remotely using outpatient medications at home" as the first step, 11.2% (22/196) preferred procedures, 6.1% (12/196) favored an infusion center, 6.1% (12/196) sent patients to the emergency department (ED) or urgent care, and 0.5% (1/196) preferred direct hospital admission. The top five preferred medications were as follows: (1) corticosteroids (71.4%, 140/196), (2) nonsteroidal anti-inflammatory drugs (NSAIDs) (50.1%, 99/196), (3) neuroleptics (46.9%, 92/196), (4) triptans (30.6%, 60/196), and (5) dihydroergotamine (DHE) (21.4%, 42/196). CONCLUSIONS: Healthcare professionals with expertise in headache medicine typically treated severe migraine attacks early and did not wait 72 h to fulfill the diagnostic criteria for SM. Outpatient management with one or more medications for home use was preferred by most respondents; few opted for ED referrals. Finally, corticosteroids, NSAIDs, neuroleptics, triptans, and DHE were the top five preferred treatments for home SM management.

Computational model of the cancer necrotic core formation in a tumor-on-a-chip device.

The mechanisms underlying the formation of necrotic regions within avascular tumors are complex and poorly understood. In this paper, we investigate the formation of a necrotic core in a 3D tumor cell culture within a microfluidic device, considering oxygen, nutrients, and the microenvironment acidification by means of a computational-mathematical model. Our objective is to simulate cell processes, including proliferation and death inside a microfluidic device, according to the microenvironmental conditions. We employed approximation utilizing finite element models taking into account glucose, oxygen, and hydrogen ions diffusion, consumption and production, as well as cell proliferation, migration and death, addressing how tumor cells evolve under different conditions. The resulting mathematical model was examined under different scenarios, being capable of reproducing cell death and proliferation under different cell concentrations, and the formation of a necrotic core, in good agreement with experimental data reported in the literature. This approach not only advances our fundamental understanding of necrotic core formation but also provides a robust computational platform to study personalized therapeutic strategies, offering an important tool in cancer research and treatment design.

Sleep Quality in CrossFit: A Cross-Sectional Study.

Objective Based on the relationship between sleep and sports performance, the present study aimed to evaluate sleep quality and excessive daytime sleepiness among adult CrossFit (CrossFit, LLC, Santa Cruz, CA, USA) practitioners and to verify possible associations with intestinal health. Methods This cross-sectional study involved males and females aged ≥ 18 years who had been regularly practicing CrossFit for at least 3 months. This survey used an online questionnaire addressing demographic and socioeconomic data, disease history, dietary characteristics, and questions regarding CrossFit. To assess intestinal health, the ROME IV Consensus Criteria and Bristol Scale were used. The Pittsburgh International Sleep Quality Index (PSQI-BR) and Epworth Sleepiness Scale were used to assess sleep quality. Results A total of 1,090 people (73.3% females) with a mean age of 31.2 ± 7.5 years were included. Considering the diagnosis of constipation, 36.9% of the patients were classified as constipated, especially females when compared with males ( p < 0.001). On the sleepiness scale, 22.4% of the volunteers showed excessive daytime sleepiness, which was also observed more frequently among females ( p = 0.013). In the PSQI-BR, 47.4% of participants were classified as having poor sleep quality (poor sleepers). The overall PSQI-BR score was 5.81 ± 2.85, with no difference between males and females ( p = 0.360). There was a positive correlation between the PSQI-BR global score and a diagnosis of constipation and excessive daytime sleepiness. There was a negative correlation between the stool type on the Bristol scale and the PSQI-BR global score. Conclusion The present study demonstrated that sleep quality was poor among CrossFit users, especially females, which can compromise their training performance.

Health equity, care access and quality in headache - part 1.

Current definitions of migraine that are based mainly on clinical characteristics do not account for other patient's features such as those related to an impaired quality of life, due to loss of social life and productivity, and the differences related to the geographical distribution of the disease and cultural misconceptions which tend to underestimate migraine as a psychosocial rather than neurobiological disorder.Global differences definition, care access, and health equity for headache disorders, especially migraine are reported in this paper from a collaborative group of the editorial board members of the Journal of Headache and Pain. Other components that affect patients with migraine, in addition to the impact promoted by the migraine symptoms such as stigma and social determinants, are also reported.

Expression of SmATPDases 1 and 2 in Schistosoma mansoni eggs favours IL-10 production in infected individuals.

A role of IL-10 is down-regulating T-cell responses to schistosome antigens. Since SmATPDases can be correlated to modulation of the immune response, we evaluated the expression of enzymes in S. mansoni eggs. Faecal samples were collected from 40 infected individuals to detect coding regions of the SmATPDases. The cytokines were measured in supernatants of PBMC. The analysis was performed by the global median determination and set up high producers (HP) of cytokines. Six individuals expressed SmATPDase1, six expressed SmATPDase2 and six expressed both enzymes. The group who expressed only SmATPDase1 showed a high frequency of IFN-γ, TNF IL-4 HP; individuals who expressed only SmATPDase2 showed a high frequency of IFN-γ, IL-6 and IL-4 HP; and individuals who expressed both enzymes showed a high frequency of IL-10 HP. The comparison of the IFN-γ/IL-10 ratio presented higher indices in the group who had SmATPDase 2 expression than those who had the expression of both enzymes. The positive correlation between infection intensity and IL-10 levels remained only in the positive SmATPDase group. The IL-10 is the only cytokine induced by the expression of both enzymes. Our data suggest that the expression of both enzymes seems to be a factor that modulates the host immune response by inducing high IL-10 production.

Modification of resting metabolism, body composition, and muscle strength after resolution of coronavirus disease 2019.

BACKGROUND & AIMS: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes changes that can influence human metabolism and modify the distribution of body compartments. We aimed to describe the clinical findings of changes in resting metabolism, muscle strength, and body composition in nonhospitalized patients after being diagnosed with coronavirus disease 2019 (COVID-19). METHODS: Physically active patients were evaluated at a nutrition clinic, and indirect calorimetry (IC) and body composition analysis using portable ultrasound were performed. After a routine appointment, all patients were instructed to inform the staff if they tested positive for SARS-CoV-2 infection. Our sample included individuals diagnosed with COVID-19, confirmed by real-time reverse transcription polymerase chain reaction (RT-PCR), within 7 days of the routine appointment. After an average incubation period of 14-21 days, in which there was no proven transmission of disease by RT-PCR, all of the patients were re-evaluated. RESULTS: A total of 38 volunteers (63.2% female) completed the study and were included in the analysis. The mean age of the participants was 37.3 ± 8.8 years. The comparison between pre- and post-COVID-19 stratified by sex demonstrated significant reduction in the RMR and RMR adjusted for weight (p < 0.0001) for both groups. Regarding body composition, there was a significant increase observed in fat mass in men (p < 0.002) and women (p < 0.01), and a significant reduction observed in fat-free mass (men: p < 0.002; women: p < 0.001) and skeletal muscle mass (men: p = 0.003; women: p < 0.0001). There was a significant difference between the change in the RMR measured by IC (p < 0.0001) and that calculated by the predictive equation of Cunningham (1980) (p < 0.0001), whereas the Harris and Benedict (1918) and Mifflin (1990) equations exhibited no difference. However, the mean difference in RMR between the post- and pre-COVID-19 calculated by the Cunningham equation was -40.4 kcal/day (95% confidence interval [CI]: -56.38 to -24.45), whereas the mean difference measured by IC was -362.3 kcal/day (95% CI: -452.7 to -271.9). CONCLUSION: This study describes the trends in the RMR, and body composition in individuals with COVID-19 who were not hospitalized from the pre-COVID-19 period to the post-COVID-19 period. A significant reduction in resting energy expenditure, and loss of fat-free mass and muscle mass in the post-COVID-19 period were observed in both men and women.

Hipogamaglobulinemia e rituximabe: relato de casos / Hypogammaglobulinemia and rituximab: case reports

Secondary immunodeficiency can result from neoplasms, infections, or immunosuppressive therapy. Rituximab (RTX) is an anti-CD20 antibody that depletes B lymphocytes and can induce symptomatic hypogammaglobulinemia. We report 3 cases of symptomatic hypogammaglobulinemia associated with the use of RTX. In patient 1 with rheumatoid arthritis, RTX induced low levels of immunoglobulins and recurrent airway infections. RTX discontinuation led to a normalization of the humoral immune response. Patients 2 and 3, treated with RTX for non-Hodgkin lymphoma and systemic lupus erythematosus, respectively, developed persistent secondary hypogammaglobulinemia requiring immunoglobulin replacement therapy for years. After RTX discontinuation, patients may experience rapid recovery of humoral function or remain with low serum immunoglobulin levels for extended periods. With the increasing use of therapies targeting components of the immune system, a high degree of clinical suspicion for the development of secondary immunodeficiency may minimize the morbidity and mortality associated with these therapies.

As imunodeficiências secundárias podem ser uma consequência de neoplasias, infecções ou tratamentos imunossupressores. O rituximabe (RTX) é um anticorpo anti-CD20 que depleta os linfócitos B e pode induzir uma hipogamaglobulinemia sintomática. Aqui, relatamos três casos de hipogamaglobulinemia sintomática associada ao uso de RTX. Na primeira paciente com artrite reumatoide, o RTX induziu a baixos níveis de imunoglobulinas associadas a infecções de vias aéreas de repetição. Após a suspensão do RTX, houve normalização da resposta imune humoral. Os outros dois casos, com o uso de RTX para tratamento de linfoma não-Hodgkin e lúpus eritematoso sistêmico, respectivamente, as pacientes evoluíram com hipogamaglobulinemia secundária persistente, com necessidade de reposição de imunoglobulina por vários anos. Pacientes tratados com RTX podem apresentar, após a sua suspensão, uma recuperação rápida da função humoral ou permanecerem com baixos níveis séricos de imunoglobulinas por longos períodos. Com o crescente uso dos tratamentos direcionados para componentes do sistema imunológico, um alto grau de suspeição clínica para o aparecimento de imunodeficiências secundárias pode minimizar a morbimortalidade associada a estes tratamentos.

Objective: to compare the occurrence of morbidity and mortality from pneumonia in the State of Bahia, in the period before and during the COVID-19 pandemic. Methodology: this is an ecological, quantitative study, with public data, available in the Health Information System of the DataSUS/TABNet platform, referring to the State of Bahia, from Jan./2018 to Dec./2021. Selected data: hospitalizations, average hospitalization, deaths and mortality rate. Data were analysed using descriptive statistics, relative frequency, and analytical statistics with the Mann-Whitney U relative frequency test. Results: the State of Bahia recorded a total of 48,000 hospitalizations for pneumonia, with an average hospitalization stay rate of 6.4 days and a total of 8,000 deaths, with an average mortality rate of 16.91% per year. It is observed that there was a reduction in hospitalizations and deaths, and an increase in the mortality rate due to pneumonia, in the studied period (P<0.001). Conclusion: however, it was found that in the State of Bahia during the period of the COVID-19 pandemic, there was a reduction in the number of hospitalizations and deaths, and an increase in the mortality rate due to pneumonia, compared to the same pre-pandemic period.

Physical-biological drivers modulating phytoplankton seasonal succession along the Northern Antarctic Peninsula.

The Northern Antarctic Peninsula (NAP) shows shifts in phytoplankton distribution and composition along its warming marine ecosystems. However, despite recent efforts to mechanistically understand these changes, little focus has been given to the phytoplankton seasonal succession, remaining uncertainties regarding to distribution patterns of emerging taxa along the NAP. To fill this gap, we collected phytoplankton (pigment and microscopy analysis) and physico-chemical datasets during spring and summer (November, February and March) of 2013/2014 and 2014/2015 off the NAP. Satellite measurements (sea surface temperature, sea ice concentration and chlorophyll-a) were used to extend the temporal coverage of analysis associated with the in situ sampling. We improved the quantification and distribution pattern of emerging taxa, such as dinoflagellates and cryptophytes, and described a contrasting seasonal behavior and distinct fundamental niche between centric and pennate diatoms. Cryptophytes and pennate diatoms preferentially occupied relatively shallower mixing layers compared with centric diatoms and dinoflagellates, suggesting differences between these groups in distribution and environment occupation over the phytoplankton seasonal succession. Under colder conditions, negative sea surface temperature anomalies were associated with positive anomalies of sea ice concentration and duration. Therefore, based on sea ice-phytoplankton growth relationship, large phytoplankton biomass accumulation was expected during the spring/summer of 2013/2014 and 2014/2015 along the NAP. However, there was a decoupling between sea ice concentration/duration and phytoplankton biomass, characterizing two seasonal periods of low biomass accumulation (negative chlorophyll-a anomalies), associated with the top-down control in the region. These results provide an improved mechanistic understanding on physical-biological drivers modulating phytoplankton seasonal succession along the Antarctic coastal waters.

Interplay among differential exposure to Mycobacterium leprae and TLR4 polymorphism impacts the immune response in household contacts of leprosy patients.

Introduction: The aim of the present study was to investigate the association between the single nucleotide polymorphism (SNP) rs1927914 A/G in TLR4 gene and the immunological profile of household contacts (HHC) of leprosy patients. Leprosy classification is usually complex and requires the assessment of several clinical and laboratorial features. Methods: Herein, we have applied distinct models of descriptive analysis to explore qualitative/quantitative changes in chemokine and cytokine production in HHC further categorized according to operational classification [HHC(PB) and HHC(MB)] and according to TLR4SNP. Results and discussion: Our results showed that M. leprae stimuli induced an outstanding production of chemokines (CXCL8;CCL2; CXCL9; CXCL10) by HHC(PB), while increase levels of pro-inflammatory cytokines (IL-6; TNF; IFN-γ; IL-17) were observed for HHC(MB). Moreover, the analysis of chemokine and cytokine signatures demonstrated that A allele was associated with a prominent soluble mediator secretion (CXCL8; CXCL9; IL-6; TNF; IFN-γ). Data analysis according to TLR4 SNP genotypes further demonstrated that AA and AG were associated with a more prominent secretion of soluble mediators as compared to GG, supporting the clustering of AA and AG genotypes into dominant genetic model. CXCL8, IL-6, TNF and IL-17 displayed distinct profiles in HHC(PB) vs HHC(MB) or AA+AG vs GG genotype. In general, chemokine/cytokine networks analysis showed an overall profile of AA+GA-selective (CXCL9-CXCL10) and GG-selective (CXCL10-IL-6) axis regardless of the operational classification. However, mirrored inverted CCL2-IL-10 axis and a (IFN-γ-IL-2)-selective axis were identified in HHC(MB). CXCL8 presented outstanding performance to classify AA+AG from GG genotypes and HHC(PB) from HHC(MB). TNF and IL-17 presented elevated accuracy to classify AA+AG from GG genotypes and HHC(PB) (low levels) from HHC(MB) (high levels), respectively. Our results highlighted that both factors: i) differential exposure to M. leprae and ii) TLR4 rs1927914 genetic background impact the immune response of HHC. Our main results reinforce the relevance of integrated studies of immunological and genetic biomarkers that may have implications to improve the classification and monitoring of HHC in future studies.

Do Antimicrobial Photodynamic Therapy and Low-Level Laser Therapy Influence Oral Health-Related Quality of Life After Molar Extraction?

PURPOSE: Most individuals experience significant deterioration in their oral health-related quality of life (OHRQoL) in the first few days after tooth extraction. This study aimed to evaluate the impact of antimicrobial photodynamic therapy (aPDT) and low-level laser therapy (LLLT) protocols on OHRQoL after extraction of lower molars. METHODS: The investigators designed a double-blind, randomized controlled clinical trial study. Patients with indications for lower molar extraction were included in the study and randomized into four groups: control group, antimicrobial photodynamic therapy group, LLLT group (LLLT.G), and aPDT and LLLT group (aPDT + LLLT.G).The Oral Health Impact Profile (OHIP-14) questionnaire was used through an interview with the participants before the extraction (T0 - baseline) and on the 7th (T1) and 30th (T2) days after extraction. Other variables were age, sex, ethnicity, decayed-missing-filled teeth (DMFT) and tooth types. Appropriate univariate and bivariate statistics were computed, and statistical significance was set at a value P < .05. RESULTS: The sample was composed of 40 patients with a mean age of 41.25 ± 13.97 and 25 (62.5%) were women. The mean OHIP-14 scores were significantly different in the intervals at T0 versus T1 and T0 versus T2 for all domains (P < .001), demonstrating a positive impact on the OHRQoL. The total scores indicated a significant improvement in the OHRQoL in the aPDT (7.10, standard deviation 4.18, P = .043), LLLT (6.40, SD 5.87, P = .025), and aPDT + LLLT (5.30, SD 3.59, P = .012) groups compared to that in the control group (12.90, SD 6.64) at T1. Patients undergoing extraction of lower mandibular molars with aPDT + LLLT had the lowest mean OHIP-14 total score at T1 (5.30) and T2 (0.70). CONCLUSION: The aPDT and LLLT protocols had a positive impact on the participants' OHRQoL. These procedures can be applied in everyday surgical practice.

Relação do ato de comer com o controle da doença e a qualidade de vida no diabetes mellitus tipo 1 / Relationship between eating behavior and disease control on the quality of life in type 1 diabetes mellitus

O objetivo deste estudo foi analisar a relação do ato de comer com o controle da doença e a qualidade de vida em adultos com diabetes tipo 1 (DM1). Trata-se de estudo transversal, realizado através de um questionário on-line com a versão brasileira do Diabetes Quality of Life Measure (DQOL-Brasil) e de perguntas sobre controle alimentar. Foram incluídos 103 voluntários (85,4% mulheres). Nas relações com a comida, 68,9% disseram sentir vontade de comer quando estão ansiosos, preocupados ou tensos. O escore global foi de 2,36 ± 0,75 no DQOL-Brasil, e os domínios "satisfação" e "preocupações relacionadas ao diabetes" apresentaram valores mais altos. A variável idade teve correlação negativa com o escore global do DQOL-Brasil e com os domínios "impacto", "preocupações sociais/vocacionais" e "preocupações com diabetes". Esta pesquisa demonstrou associação entre o ato de comer com o controle do DM1, o que pode prejudicar a qualidade de vida desses indivíduos.

This study aimed to analyze the relationship between eating behavior, disease control, and quality of life in adults with type 1 diabetes mellitus (DM1). This cross-sectional study was conducted using an online questionnaire based on the Brazilian version of the Diabetes Quality of Life Measure (DQOL-Brazil), comprising questions on dietary control. A total of 103 volunteers (85.4% women) were included in this study. In relation to food, 68.9% said that they felt like eating when they were anxious, worried, or tensed. The overall score was 2.36 ± 0.75 on the DQOL-Brazil, with higher scores for the domains "satisfaction" and "diabetes-related concerns." The age variable had a negative correlation with the global DQOL-Brazil score and with the domains "impact," "social/vocational concerns," and "diabetes-related concerns." This study demonstrated an association between the act of eating and DM1 control, affecting the quality of life in these individuals.

Place of next generation acute migraine specific treatments among triptans, non-responders and contraindications to triptans and possible combination therapies.

Background: For many years triptans have been the cornerstone of acute migraine treatment. Nevertheless, treatment with triptans may not always be initiated due to contraindications (seen in approximately one fifth of patients) or inadequate response (seen in approximately one third of patients). New acute therapies, including 5-hydroxytryptamine (5-HT)1F receptor agonists, also known as ditans (lasmiditan) and small molecule antagonists of the calcitonin gene-related peptide receptor, also known as gepants (rimegepant and ubrogepant), may be an effective alternative. Methods: We searched Pubmed for keywords, summarized the literature and provided a comprehensive review on the place of next generation acute migraine specific treatments among triptans. Results and conclusion: Post-hoc analyses reported no differences in efficacy of gepants/ditans between responders and non-responders to triptans, but research is hampered by lack of consensus on the definition of non-responder. Due to (partially) overlapping mechanisms of action, it remains unknown whether combination therapy with lasmiditan, gepants and triptans will have added value over monotherapy. Preclinical studies and post-hoc analyses cautiously indicate that these new drugs are safe for patients with cardiovascular risk factors. However, long-term studies are needed to prove cardiovascular safety. The risk of developing medication overuse headache may differ between triptans, ditans and gepants, but further studies are needed to confirm this difference. Head-to-head randomized controlled trials of acute therapies and combinations of therapies are needed to determine their place in migraine treatment among established therapies.

Factors Associated with the Lifestyle of Pediatric Healthcare Professionals during the COVID-19 Pandemic.

The objective of this study was to analyze the association between sociodemographic and occupational variables with the lifestyle of health professionals in pediatric units during the COVID-19 pandemic. A cross-sectional study was conducted with 407 health professionals working in four pediatric health units in the State of Bahia, northeast Brazil. The Fantastic Lifestyle Questionnaire and a questionnaire with sociodemographic and employment variables self-applied via Google Forms were used. The final binary logistic regression models revealed significant associations between those who received 3 to 5 minimum wages, without a marital relationship and with more than one employment relationship. Data suggest that these sociodemographic and occupational profiles are more exposed to risky lifestyle behaviors. The findings of this study demonstrated the need for greater attention to the health of health professionals in the pediatric field, as well as the promotion of initiatives that seek to value the work of these professionals and reduce the damage caused to their lifestyle, especially in a pandemic scenario.

BDNF rs6265 differentially influences neurometabolites in the anterior cingulate of healthy and bipolar disorder subjects.

Brain-derived neurotrophic factor (BDNF) is the most abundant brain neurotrophin and plays a critical role in neuronal growth, survival and plasticity, implicated in the pathophysiology of Bipolar Disorders (BD). The single-nucleotide polymorphism in the BDNF gene (BDNF rs6265) has been associated with decreased hippocampal BDNF secretion and volume in met carriers in different populations, although the val allele has been reported to be more frequent in BD patients. The anterior cingulate cortex (ACC) is a key center integrating cognitive and affective neuronal connections, where consistent alterations in brain metabolites such as Glx (Glutamate + Glutamine) and N-acetylaspartate (NAA) have been consistently reported in BD. However, little is known about the influence of BDNF rs6265 on neurochemical profile in the ACC of Healthy Controls (HC) and BD subjects. The aim of this study was to assess the influence of BDNF rs6265 on ACC neurometabolites (Glx, NAA and total creatine- Cr) in 124 euthymic BD type I patients and 76 HC, who were genotyped for BDNF rs6265 and underwent a 3-Tesla proton magnetic resonance imaging and spectroscopy scan (1 H-MRS) using a PRESS ACC single-voxel (8cm3) sequence. BDNF rs6265 polymorphism showed a significant two-way interaction (diagnosis × genotype) in relation to NAA/Cr and total Cr. While met carriers presented increased NAA/Cr in HC, BD-I subjects with the val allele revealed higher total Cr, denoting an enhanced ACC metabolism likely associated with increased glutamatergic metabolites observed in BD-I val carriers. However, these results were replicated only in men. Therefore, our results support evidences that the BDNF rs6265 polymorphism exerts a complex pleiotropic effect on ACC metabolites influenced by the diagnosis and sex.

O papel da atenção primária na rede de atenção à saúde frente ao manejo da hanseníase: um estudo transversal / he role of primary carein the health care network in front of leprosy management: a cross-sectional study

Objetivou-se analisar o perfil demográfico e clínico dos casos de hanseníase e associar os fatores relacionadas às incapacidades físicas com a Atenção Primária à Saúde(APS)na perspectiva de Redes de Atenção à Saúde em Sinop, Mato Grosso. Trata-se de um estudo transversal, que percorreu três etapas analíticas: conhecimento do perfil epidemiológico; classificação da capacidade da Atenção Primária em coordenar as Redes de Atenção à Saúde; correlação dessa classificação com o número de casos novos, desfecho e o Grau de Incapacidade Física e correlação do número de casos novos e a média de cobertura da Atenção Primária por meio do coeficiente de correlação de Pearson. Foram considerados os casos novos de hanseníase notificados no período de 2014 a 2018. Dos 1.649 casos novos, 63% foram mulheres, entre 15 e 59 anos (83%),com até nove anos de estudo (47%),e negros (61%). Cura respondeu por 86% dos registros. Predomínio de Grau de incapacidade física0no diagnóstico (58%) e ausência de avaliação no desfecho (17,1%). Todas as Atenção Primária à Saúde foram classificadas como 'condição boa' na coordenação das Redes de Atenção. O abandono apresentou 'correlação moderada' com a capacidade da Atenção Primária em coordenar as Redes de Atenção e a média de cobertura da Atenção Primária com o número de casos indicou correlação 'muito alta'. A Atenção Primária, na perspectiva da Rede de Atenção, se mostrou efetiva no controle e na condução da hanseníase no território municipal.

The objective was to analyze the clinical epidemiological profile of leprosy cases and associate this profile with primary health care from the perspective of health care networks. This is a cross-sectional study that covered three analytical stages: knowledge of the epidemiological profile; classification of the capacity of the APS to coordinate the RAS; correlation of this classification withthe numberof new cases, outcome and the Degree of Physical Disability (GIF),and correlation of the number of new cases and the average coverage of PHC, using the Pearson correlation coefficient. New cases of leprosy reported in the period from 2014 to 2018 were considered. Of the 1,649 new cases, 63% were women, between 15 and 59years (83%), with up to nine years of education (47%) and black (61% ). Healing accounted for 86% of the records. The predominance of GIF 0 in the diagnosis (58%) and absence ofevaluation in the outcome (16%). All UBS were classified as 'good condition' in the RAS coordination. Dropout showed a 'moderate correlation' with the PHC's ability to coordinate the RAS and the mean PHC coverage with the number of cases indicated a 'veryhigh' correlation. APS, from the perspective of RAS, proved to be effective in controlling and managing leprosy in the municipal territory.

Macronutrients, iron and humic substances summer cycling over the extended continental shelf of the South Brazil Bight.

We surveyed macronutrients and dissolved iron (DFe) concentrations and speciation in a transect over the shelf of the South Brazil Bight (SBB) at Santa Marta Grande Cape (SE Brazil) during a coastal downwelling episode. Driven by dominant NE winds, coastal downwelling is a common feature during the austral summer and force after water convergence, with contribution of internal wave breaking at the shelf edge, upwelling of macronutrients into the nutrient-depleted waters of the southbound Brazil Current at ~100 km from the coastline. As a result, we found a plume of high turbidity that reached the euphotic layer, a deepening of the silicate, nitrate, and phosphate isolines over the shelf and a bulging of the nitrate and phosphate isolines over the shelf edge and the slope. Our first measurements of DFe concentration and speciation in the area revealed that against prior findings in other coastal areas, macronutrients, DFe, and iron ligand cycles were disentangled. Higher DFe concentrations were often found at the surface indicating aerial deposition. Secondary DFe maxima over the sediment-water interface and in the upwelled plume indicated DFe fluxes from the sediment and from resuspended instable colloids. Iron ligand concentrations were higher than DFe concentrations in most stations with a clear land-to-ocean gradient. Subtraction of HS iron ligands revealed that except in upwelled water, the bulk of surface ligands was the result of local biological processes. The analysis of the concentrations of Fe-HS complexes showed that the contribution of HS to DFe was dominant in upwelled waters, significant in waters close to the coast, but nearly negligible in the rest of the studied area. We hypothesize that the injection of iron-humic complexes into the euphotic layer during summer upwelling episodes is the key to understanding the persistent high chlorophyll meanders found over the shelf edge of the SBB coast.

Rural work and COVID-19: challenges and proposals for the prevention of damages.

The COVID-19 pandemic has highlighted the inequalities in health care access in Brazil, exarcerbating vulnerabilities and social determinants of health. Inequality is part of the context of rural populations, especially rural workers and family and subsistence farmers due to both the direct consequences of work activity and the unfavorable socioeconomic context, especially regarding service provision, the guaranteeing of rights, and the coordination of care networks. This article reviews challenges to the health of these workers and outlines proposals for disease prevention in the context of the COVID-19 pandemic.

Apandemia de covid-19 no mundo trouxe à tona as desigualdades vivenciadas no acesso à saúde no Brasil, escancarando as vulnerabilidades e os determinantes sociais de saúde. É nesse ínterim de iniquidades que as populações rurais se inserem, em especial trabalhadores e trabalhadoras rurais e membros da agricultura familiar e de subsistência, tanto pelas consequências diretas da atividade laboral quanto pelo contexto socioeconômico desfavorável, especialmente no que diz respeito a oferta de serviços, garantia de direitos e articulação das redes de assistência. Frente a isso, o presente trabalho discute os desafios relacionados à saúde desses trabalhadores e traça propostas para a prevenção de agravos da referida população no contexto da pandemia de covid-19.
