Adenomas from individuals with pathogenic biallelic variants in the MUTYH and NTHL1 genes demonstrate base excision repair tumour mutational signature profiles similar to colorectal cancers, expanding potential diagnostic and variant classification applications.

Background: Colorectal cancers (CRCs) from people with biallelic germline likely pathogenic/pathogenic variants in MUTYH or NTHL1 exhibit specific single base substitution (SBS) mutational signatures, namely combined SBS18 and SBS36 (SBS18+SBS36), and SBS30, respectively. The aim was to determine if adenomas from biallelic cases demonstrated these mutational signatures at diagnostic levels. Methods: Whole-exome sequencing of FFPE tissue and matched blood-derived DNA was performed on 9 adenomas and 15 CRCs from 13 biallelic MUTYH cases, on 7 adenomas and 2 CRCs from 5 biallelic NTHL1 cases and on 27 adenomas and 26 CRCs from 46 non-hereditary (sporadic) participants. All samples were assessed for COSMIC v3.2 SBS mutational signatures. Results: In biallelic MUTYH cases, SBS18+SBS36 signature proportions in adenomas (mean±standard deviation, 65.6%±29.6%) were not significantly different to those observed in CRCs (76.2%±20.5%, p-value=0.37), but were significantly higher compared with non-hereditary adenomas (7.6%±7.0%, p-value=3.4×10-4). Similarly, in biallelic NTHL1 cases, SBS30 signature proportions in adenomas (74.5%±9.4%) were similar to those in CRCs (78.8%±2.4%) but significantly higher compared with non-hereditary adenomas (2.8%±3.6%, p-value=5.1×10-7). Additionally, a compound heterozygote with the c.1187G>A p.(Gly396Asp) pathogenic variant and the c.533G>C p.(Gly178Ala) variant of unknown significance (VUS) in MUTYH demonstrated high levels of SBS18+SBS36 in four adenomas and one CRC, providing evidence for reclassification of the VUS to pathogenic. Conclusions: SBS18+SBS36 and SBS30 were enriched in adenomas at comparable proportions observed in CRCs from biallelic MUTYH and biallelic NTHL1 cases, respectively. Therefore, testing adenomas may improve the identification of biallelic cases and facilitate variant classification, ultimately enabling opportunities for CRC prevention.

The protective and destructive critical processes of female labor in small-scale fishing in coast Pernambuco, Brazil. / Processos críticos protetores e destrutivos no trabalho das pescadoras artesanais do litoral Pernambucano, Brasil.

This study aims to analyze the protective and destructive critical processes of 34 water women in the municipalities of Cabo de Santo de Agostinho and Ipojuca, Pernambuco, Brazil, from February/21 to August/22. The work process stages were systematized by the work flowchart, and we employed Breilh's critical processes matrix to organize the data. The destructive processes identified in the general domain were injustice and socio-environmental vulnerability, such as the economic development model, the Suape Industrial Port Complex, the 2019 oil spill crime disaster, the COVID-19 pandemic, and the difficult access to public policies; in the particular domain: overloads and extended working hours, use of rudimentary equipment and tools, and unequal gender, class, and race relationships; in the singular domain: physical and mental illnesses and deaths. The protective processes identified in the general domain were sustainable development objectives, public health, and social assistance policies; in the particular domain, group work and processing, consumption for subsistence; in the singular domain, fishing as a therapeutic, pleasurable, and sharing process. The study highlighted the central issues of the water women and the need to establish public policies targeting their care.

Exploring the Effects of Freeze-Dried Sourdoughs with Lactiplantibacillus pentosus 129 and Limosilactobacillus fermentum 139 on the Quality of Long-Fermentation Bread.

Sourdough production is a complex fermentation process. Natural sourdough fermentation without standardization causes great variability in microbial communities and derived products. Starter cultures have emerged as alternatives to natural fermentation processes, which could improve bakery quality and produce bioactive compounds. This study aimed to evaluate the impacts of freeze-drying on the production and viability of sourdoughs with Lactiplantibacillus pentosus 129 (Lp) and Limosilactobacillus fermentum 139 (Lf), as well as their effects on the quality of long-fermentation bread. These strains were selected based on their better performance considering acidification and exopolysaccharide production capacity. Sourdough with Lp and Lf were propagated until the 10th day, when physicochemical and microbiological parameters were determined. The produced sourdoughs were freeze-dried, and bread samples were produced. The freeze-drying process resulted in high survival rates and few impacts on the metabolic activity of Lp and Lf until 60 days of storage. Incorporating Lp and Lf improved the microbiological and physicochemical properties of sourdough and long-fermentation breads. Tested freeze-dried sourdoughs led to reduced bread aging (higher specific volume and decreased starch retrogradation) and increased digestibility. The results show the potential of the freeze-dried sourdoughs produced with Lp and Lf as innovative strategies for standardizing production protocols for the bakery industry, especially for producing long-term fermentation bread.

Cannabidiol in the dorsal hippocampus attenuates emotional and cognitive impairments related to neuropathic pain: The role of prelimbic neocortex-hippocampal connections.

BACKGROUND AND PURPOSE: Chronic neuropathic pain (NP) is commonly associated with cognitive and emotional impairments. Cannabidiol (CBD) presents a broad spectrum of action with a potential analgesic effect. This work investigates the CBD effect on comorbidity between chronic NP, depression, and memory impairment. EXPERIMENTAL APPROACH: The connection between the neocortex and the hippocampus was investigated with biotinylated dextran amine (BDA) deposits in the prelimbic cortex (PrL). Wistar rats were submitted to chronic constriction injury (CCI) of the sciatic nerve and CA1 treatment with CBD (15, 30, 60 nmol). KEY RESULTS: BDA-labeled perikarya and terminal buttons were found in CA1 and dentate gyrus. CCI-induced mechanical and cold allodynia increased c-Fos protein expression in the PrL and CA1. The number of astrocytes in PrL and CA1 increased, and the number of neuroblasts decreased in CA1. Animals submitted to CCI procedure showed increasing depressive-like behaviors, such as memory impairment. CBD (60 nmol) treatment decreased mechanical and cold allodynia, attenuated depressive-associated behaviors, and improved memory performance. Cobalt chloride (CoCl2: 1 nM), WAY-100635 (0.37 nmol), and AM251 (100 nmol) intra-PrL reversed the effect of CA1 treatment with CBD (60 nmol) on nociceptive, cognitive, and depressive behaviors. CONCLUSION: CBD represents a promising therapeutic perspective in the pharmacological treatment of chronic NP and associated comorbidities such as depression and memory impairments. The CBD effects possibly recruit the CA1-PrL pathway, inducing neuroplasticity. CBD acute treatment into the CA1 produces functional and molecular morphological improvements.

Antimicrobial resistance, enterotoxin and biofilm production genes in Staphylococcus spp. isolated from facilities and fomites in veterinary hospital in the Caatinga biome.

The Caatinga biome occurs only in Brazil and offers epidemiological conditions that should be assessed differently from other regions of Brazil and the world. Thus, the aim of this survey was to identify antimicrobial resistance, enterotoxin and biofilm production genes in Staphylococcus spp. isolated from facilities and fomites in a veterinary hospital in Caatinga biome. Samples were collected from surfaces of small animal clinical care tables (n =8), cages in the dog and cat hospitalisation sector and animals with infectious diseases (n = 21), small animal surgical centre (n =8), sterilisation sector (n =7) and stethoscopes (n = 32) by using sterile swabs. Bacterial isolation and identification, antimicrobial resistance phenotypic test and molecular detection of antimicrobial resistance, biofilm formation and enterotoxin genes were carried out. Ninety-five bacterial isolates were obtained, and 29 (30.5%) were identified as Staphylococcus spp. Overall, 13 isolates (44.8%) of six species of Staphylococcus spp. showed antimicrobial resistance profile, as well as S. haemolyticus expressed phenotypic profile of multidrug resistance. The antimicrobials with the highest resistance rates were penicillin and tetracycline. The most frequent resistance genes were blaZ and tetM, both detected in 10 (76.9%) isolates. The mecA, tetL and tetK genes had frequencies of 38.5% (5/13), 23.1% (3/13) and 15.4% (2/13), respectively. The biofilm production marker, icaD gene, was detected in one S. sciuri strain. SEE gene, which encodes enterotoxins, was detected in 15.4% (2/13) of the strains (S. pseudintermedius and S. intermedius). The occurrence of Staphylococcus spp. carrying resistance genes to diferent classes of antimicrobials, presenting MDR phenotypic pattern and carrying enterotoxins and biofim encoding genes recovered from veterinary hospital facilities and fomites in the Caatinga biome reinforce the need to implement prevention cares in veterinary practices to avoid One Health-concerning conditions.

Osteorradionecrose em paciente com insuficiência mitral em uso de anticoagulante antagonista de vitamina k: relato de caso

INTRODUÇÃO: A osteorradionecrose (ORN) é uma complicação associada ao tratamento radioterápico em região de cabeça e pescoço, caracteriza-se como a formação de osso necrótico e desvitalizado. Possui sinais e sintomas como dor, formação de fístula intra ou extraoral, exposição óssea, trismo, fratura patológica e sequestro ósseo. A proposta terapêutica mais eficaz é o debridamento ósseo e dos tecidos moles afetados associado a antibioticoterapia. A radioterapia reduz a vascularização do tecido, causando hipóxia e reduzindo sua capacidade de regeneração tecidual. Diante de um caso de trauma, a reparação não será efetiva e o tecido pode progredir para um tecido necrótico e desvitalizado. RELATO DE CASO: Paciente gênero feminino, 59 anos com diagnóstico de Insuficiência Mitral grave estágio D de provável etiologia reumática, fibrilação atrial em uso de anticoagulante antagonista de vitamina K, histórico de tratamento radioterápico de neoplasia de língua há oito anos e extração dentária recente. Como queixa principal, dor de difícil controle medicamentoso. Ao exame físico extraoral apresentava edema, hiperemia em região submandibular direita efístula com drenagem de exsudato purulento.No exame físico intraoral desdentada total superior e inferior sem uso de prótese dentáriacom presença de exposição óssea em rebordo alveolar de aproximadamente 5cm na região inferior anterior e posterior do lado direito. A hipótese diagnóstica foi de ORN. Conduta realizada em conjunto com equipe de cirurgia bucomaxilofacial de serviço externofoi debridamento de tecido ósseo necrótico em região de rebordo alveolar até região de parassínfise esquerda para remoção de tecido ósseo desvitalizado, antibioticoterapia e acompanhamento odontológico semanal com sessões de laserterapia de baixa potência e terapia fotodinâmica. Após a realização de cirurgia cardíaca para troca da valva paciente evoluiu com fratura patológica em mandíbula e foiencaminhada para ressecção parcial de mandíbulasob anestesia geral. No pós-operatório apresentoudiscreta assimetria facial, ausência de exposição óssea e regressão total da sintomatologia dolorosa. CONSIDERAÇÕESFINAIS: O manejo da ORN é considerado desafiador em pacientes tratados com radioterapia de cabeça e pescoço. O caso evidencia a importânciado diagnóstico e tratamento correto para evitar complicações tardias que reduzam a qualidade de vida. O cirurgião-dentista deve estar atento à prevenção dessa condição.

Manifestação bucal de intoxicação cumarínica em paciente cardiopata com miocardiopatia chagásica: relato de caso / Oral manifestation of coumarin intoxication in a heart disease patient with chagasic cardiomyopathy: case report

INTRODUÇÃO: Os anticoagulantes orais são administrados principalmente para prevenção de eventos tromboembólicos, o antagonista da Vitamina K (AVK) mais utilizado é a Varfarina, pertencente ao grupo dos cumarínicos. As diversas interações medicamentosas e alimentares podem aumentar sua biodisponibilidade sanguínea de forma a potencializar o seu efeito. O controle da anticoagulação deve ser realizado com a monitorização terapêuticado tempo de protrombina (TP) e aRazão Normalizada Internacional (RNI), cuja dose varia para cada indivíduo. A hemorragia é o efeito adverso mais comum do anticoagulante. Valores de RNI > 5 estão associados a risco de sangramento e a reversão do efeito do AVK pode ser conseguido com várias medidas, desde a simples suspensão da droga, a administração de vitamina K ou a administração de plasma fresco congelado (PFC) ou complexo protrombínico, de acordo com a urgência da situação. O sinal clínico mais frequente é o sangramento muco-cutâneo e, em casos de eventos traumáticos favorece a formação de equimose e hematomas. RELATO DE CASO: Paciente gênero masculino, 77 anos com diagnóstico de Miocardiopatia Chagásica com Insuficiência Cardíaca fração de ejeção reduzida (30%), em uso de anticoagulante antagonista de vitamina K, com histórico de queda da própria altura. Foi solicitada a interconsulta da equipe de odontologia, por sangramento ativo em cavidade oral e queixa de trauma por mordida. Ao exame físico extraoral paciente contactuante verbal, deambulante com auxílio, dieta via oral assistida e abertura mandibular preservada. No exame físico intraoral paciente desdentado superior em uso de prótese total e dentado parcial inferior em uso de prótese parcial removível, com presença de lesões arroxeadas em região de ventre lingual e assoalho bucal do lado direito e em região de dorso de língua com laceração característica de trauma por mordida do lado direito de aproximadamente 1 centímetro de diâmetro com relato de sintomatologia dolorosa. Solicitado o exame laboratorial com resultado de RNI 10.0. O diagnóstico foi hematoma como manifestação bucal de intoxicação cumarínica. Foi realizada laserterapia para analgesia e cicatrização do local traumatizado, e discussão com equipe médica que prescreveu três doses de vitamina K e duas bolsas de plasma para reversão do quadro. CONSIDERAÇÕES FINAIS: O caso apresenta a importância da avaliação odontológica para diagnóstico e tratamento imediato no contexto hospitalar e na atividade multiprofissional, além de reduzir possíveis complicações sistêmicas durante a internação.

Influência da higiene oral no desfecho clínico de pacientes hipertensos com covid-19 em um hospital cardiológico / Influence of oral hygiene on the clinical outcome of hypertensive patients with covid-19 in a cardiology hospital

INTRODUÇÃO: A COVID-19, infecção respiratória causada pelo vírus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), é capaz de provocar complicações graves devido ao mecanismo de resposta inflamatória exacerbada pelo aumento de biomarcadores inflamatórios (tempestade de citocinas). O SARS-CoV-2 tem acesso àscélulas por meio do acoplamento da proteína Spike (proteína-S) ao receptor localizado na enzima conversora de angiotensina-2 (ECA2). Pacientes hipertensos apresentam maior expressão de ECA2 devido à ação de medicamentos anti-hipertensivos, tornando-os mais vulneráveis ao contágio e complicações da COVID-19. Além dos agravos no sistema estomatognático relacionados à saúde debilitada do paciente e às intercorrências da internação, sabe-se que piores condições de saúde oral aumentam a produção de citocinas inflamatórias por ação, por exemplo, de patógenos periodontais, podendo agravar consideravelmente quadros da COVID-19. OBJETIVO: Avaliar a influência da higiene oral no desfecho clínico de pacientes hipertensos com COVID-19 em um hospital terciário de cardiologia, além de descrever as variáveis demográficas. MÉTODO: Estudo quantitativo e descritivo de prontuários odontológicos de pacientes hipertensos adultos com COVID-19 em Enfermaria e Unidade de Terapia Intensiva de um hospital cardiológico no período de março de 2021 a março de 2022. A análise das variáveis foi realizada com auxílio do software R versão 4.1.2 e testes de hipótese baseados no teste-Z para comparações entre proporções. RESULTADOS: Dentre os 79 prontuários eletrônicos avaliados, 78% apresentava diagnóstico de hipertensão arterial sistêmica. Entre os hipertensos, o gênero masculino foi o mais prevalente (75%) e a idade média foi de 64,2 anos. Cerca de 53% dos hipertensos apresentavam higiene oral insatisfatória diagnosticada pelo Índice de Higiene Oral do Paciente Crítico (IHOPC). Ao comparar a proporção de óbitos entre pacientes com higiene oral insatisfatória e a presença ou não de hipertensão arterial sistêmica, identificou-se correlação significativa entre hipertensos com higiene oral insatisfatória e piores desfechos (óbito). Conclusão: Dentro das limitações do estudo, conclui-se que hipertensos infectados por Sars- -Cov-2 e com higiene oral insatisfatória apresentam piores prognósticos. A precariedade na condição oral de doentes crônicos associada aos agravos da COVID-19 e pela própria doença de base ressalta a necessidade do reforço nos cuidados orais a doentes críticos, além de realçar a importância da presença do cirurgião-dentista em ambiente hospitalar

Anticandida and antibiofilm activities of extract from Schinopsis brasiliensis Engl. against Candida spp.

The pathogenic nature of infections caused by Candida spp. underscores the necessity for novel therapeutic agents. Extracts of Schinopsis brasilienses Engl are \ a promising source of agents with antifungal effects. This study aimed to assess the antifungal potential of the leaf extract of S. brasilienses. The antifungal activity was evaluated by determining the minimum inhibitory concentrations and fungicide concentrations (MIC and MFC). The antibiofilm potential was assessed by counting colony-forming units/mL. The study examined the inhibition kinetics of fungal growth and potential synergism between gallic acid or the extract and nystatin using the Checkerboard method. Cytotoxicity was evaluated through the MTT assay. The extract exhibited antifungal effect against all tested strains, with MIC and MFC ranging from 31.25-250 µg/mL. Gallic acid, the main isolated compound, displayed a MIC of 2000 µg/mL. The extract of S. brasilienses at 31.25 µg/mL inhibited the formation of biofilm by C. albicans and significantly reduced the mass of mature biofilm after 24 and 48 h (p < 0. 05). At a concentration of 125 µg/mL, the extract demonstrated significant inhibition of fungal growth after 6 hours. The combination of gallic acid or extract with nystatin did not exhibit synergistic or antagonistic effect. Furthermore, the extract did not induce cytotoxicity to a human cell line. The extract of S. brasiliensis demonstrates antifungal activity against Candida, generally exhibiting fungicidal action and capacity to inhibit biofilm formation as well as reduce mature biofilms. Additionally, the extract showed low cytotoxicity to human cells.

Cerebrospinal Fluid Biomarkers of Symptomatic Neurosyphilis in People With HIV Compared with Uninfected Individuals.

We evaluated the diagnostic clinical performance characteristics (DCPC) of cerebrospinal fluid (CSF) total protein (TP), white blood cell count (WBC), and lactate (LA) with different cutoff points as adjunct biomarkers of confirmed or presumptive symptomatic neurosyphilis (NS) and the impact of HIV infection. From 5,640 participants who underwent lumbar punctures, 236 participants were included, and classified as either people with HIV (PWH) or people without HIV (PWoH) according to the CDC criteria for confirmed NS (n = 42), presumptive NS (n = 74), systemic syphilis (SS) (n = 38), serological diagnosis of syphilis (n = 18), PWH without SS and NS (n = 10), and negative control (n = 72). In PWoH, for presumptive NS, the combination of CSF TP > 45 mg/dL and/or WBC > 5.0 cells/mm3 is valuable for screening, whereas in PWH, it is not recommended for either screening or case-finding NS, however the DCPC were better in the suppressed group. In PWoH, the value of CSF TP > 45 mg/dL is adequate for both screening and confirmation of presumptive NS, subject to prevalence. For WBC count > 20 cell/mm3, the positive predictive value (PPV) of the test is almost perfect, suggesting a confirmatory test. In PWH, CSF TP is an inadequate marker of NS. The WBC count, with cutoffs of > 10 or > 20 cells/mm3, was moderately applicable for screening.As conclusions: CSF WBC count and TP showed distinct DCPC in confirmed or presumptive NS, better in the former. These biomarkers could be included for presumptive NS diagnosis. DCPC of these biomarkers for the diagnosis of NS is greatly affected by HIV co-infection.

Anthropometric, Metabolic, and Endocrine Parameters as Predictors of Estimated Average Glucose and Other Biomarkers of Dysglycemia in Women with Different Phenotypes of Polycystic Ovary Syndrome.

The aim of the study was to evaluate the efficacy of anthropometric, metabolic, and endocrine abnormalities as predictors of estimated average glucose and other biomarkers of dysglycemia in women with different phenotypes of polycystic ovary syndrome (PCOS). This cross-sectional study included 648 women with PCOS and 330 controls. A single protocol of investigation was applied for all subjects. PCOS women were divided by phenotypes according to the Rotterdam criteria. Biomarkers of dysglycemia were considered dependent variables and anthropometric, lipid, and hormone alterations as independent variables using univariate and multivariate logistic regressions. Univariate logistic regression analysis, controlled for age and BMI, showed that many biomarkers of dysglycemia could be predicted by anthropometric, lipid, and endocrine variables. Multivariate logistic models showed that in non-PCOS women estimated average glucose (eAG) was predicted by lower TSH levels (OR=0.39; p=0.045); fasting glucose was predicted by increased T (OR=2.3). For PCOS, phenotype A, eAG was predicted by decreased HDL-C (OR=0.17, p=0.023) and high levels of free estradiol (OR=7.1, p<0.001). Otherwise, in PCOS, phenotype D, eAG was predicted by higher levels of HDL-C. The current study demonstrated that eAG was poorly predicted by anthropometric, lipid, and hormone parameters. Nevertheless, without adding significant benefits, it was comparable with other established markers of dysglycemia in women with different PCOS phenotypes.

Unraveling the genetic background of individuals with a clinical familial hypercholesterolemia phenotype.

Familial hypercholesterolemia (FH) is a common genetic disorder of lipid metabolism caused by pathogenic/likely pathogenic variants in LDLR, APOB, and PCSK9 genes. Variants in FH-phenocopy genes (LDLRAP1, APOE, LIPA, ABCG5, and ABCG8), polygenic hypercholesterolemia, and hyperlipoprotein (a) [Lp(a)] can also mimic a clinical FH phenotype. We aim to present a new diagnostic tool to unravel the genetic background of clinical FH phenotype. Biochemical and genetic study was performed in 1,005 individuals with clinical diagnosis of FH, referred to the Portuguese FH Study. A next-generation sequencing panel, covering eight genes and eight SNPs to determine LDL-C polygenic risk score and LPA genetic score, was validated, and used in this study. FH was genetically confirmed in 417 index cases: 408 heterozygotes and 9 homozygotes. Cascade screening increased the identification to 1,000 FH individuals, including 11 homozygotes. FH-negative individuals (phenotype positive and genotype negative) have Lp(a) >50 mg/dl (30%), high polygenic risk score (16%), other monogenic lipid metabolism disorders (1%), and heterozygous pathogenic variants in FH-phenocopy genes (2%). Heterozygous variants of uncertain significance were identified in primary genes (12%) and phenocopy genes (7%). Overall, 42% of our cohort was genetically confirmed with FH. In the remaining individuals, other causes for high LDL-C were identified in 68%. Hyper-Lp(a) or polygenic hypercholesterolemia may be the cause of the clinical FH phenotype in almost half of FH-negative individuals. A small part has pathogenic variants in ABCG5/ABCG8 in heterozygosity that can cause hypercholesterolemia and should be further investigated. This extended next-generation sequencing panel identifies individuals with FH and FH-phenocopies, allowing to personalize each person's treatment according to the affected pathway.

Processos críticos protetores e destrutivos no trabalho das pescadoras artesanais do litoral Pernambucano, Brasil / The protective and destructive critical processes of female labor in small-scale fishing in coast Pernambuco, Brazil

Resumo Objetivou-se analisar os processos críticos, protetores e destrutivos do trabalho de 34 mulheres das águas nos municípios de Cabo de Santo de Agostinho e Ipojuca (PE), de fevereiro de 2021 a agosto de 2022. As etapas do processo de trabalho foram sistematizadas pelo fluxograma do trabalho e organizadas na matriz de processos críticos de Breilh. Os processos destrutivos, no domínio geral, foram: injustiça e vulnerabilização socioambiental como modelo de desenvolvimento econômico, o Complexo Industrial Portuário de Suape, o desastre-crime de petróleo ocorrido em 2019, a pandemia de COVID-19 e dificuldade de acesso às políticas públicas; no particular: jornadas e sobrecargas de trabalho, uso de equipamentos e ferramentas rudimentares e relações desiguais de gênero, classe e raça; no singular: adoecimentos físicos, mentais e mortes. Os processos protetores, no domínio geral: os objetivos de desenvolvimento sustentável, políticas públicas de saúde e assistência social; no particular: trabalho e beneficiamento em grupo, consumo para subsistência; no singular: a pesca como processo terapêutico, prazeroso e de partilha. O estudo destacou os problemas centrais das mulheres das águas e a necessidade do estabelecimento de políticas públicas voltadas ao seu cuidado.

Abstract This study aims to analyze the protective and destructive critical processes of 34 water women in the municipalities of Cabo de Santo de Agostinho and Ipojuca, Pernambuco, Brazil, from February/21 to August/22. The work process stages were systematized by the work flowchart, and we employed Breilh's critical processes matrix to organize the data. The destructive processes identified in the general domain were injustice and socio-environmental vulnerability, such as the economic development model, the Suape Industrial Port Complex, the 2019 oil spill crime disaster, the COVID-19 pandemic, and the difficult access to public policies; in the particular domain: overloads and extended working hours, use of rudimentary equipment and tools, and unequal gender, class, and race relationships; in the singular domain: physical and mental illnesses and deaths. The protective processes identified in the general domain were sustainable development objectives, public health, and social assistance policies; in the particular domain, group work and processing, consumption for subsistence; in the singular domain, fishing as a therapeutic, pleasurable, and sharing process. The study highlighted the central issues of the water women and the need to establish public policies targeting their care.

Antibacterial and antifungal activity of curcumin and methylene blue associated with laser on bacterial and fungal strains

Objective:To analyze the effect of methylene blue and 10% curcumin in fungi and bacteria through an in vitrostudy using photodynamic therapy (PDT). Methods:Curcumin and methylene blue were photosensitized by a Photon Lase III laser applied for 90 s in a dark environment within a laminar flow chamber. Enterococcus faecalisand Candida albicans strains were cultured and standardized.Then, a minimum inhibitoryconcentration (MIC) assay was conducted for these photosensitizers, with concentration variations and incubation to evaluate their antimicrobial activity. Results:With PDT, Curcumin had significant antibacterial activity against E. faecalis (MIC = 250 µg/mL).In contrast, methylene blue had antibacterial activity against E. faecalis (MIC < 12.5 µg/mL with PDT) and antifungal activity against C. albicans (MIC <12.5 µg/mL with or without PDT).Both agents showed greater efficacy in the presence of the laser.The results suggest that curcumin and methylene blue associated with laser may effectively treat microbial infections. Conclusion:Further research is needed to evaluate the efficacy and safety of using these agents in animal and human models and theireffectiveness against different bacterial and fungal strains.

Food consumption profile of rural riverside populations.

INTRODUCTION: The uniqueness of the way of life of rural riverside populations is of interest because they are the largest traditional Amazonian population. Their eating habits reveal their life conditions and relationship with the urban environment and is a poorly investigated subject. This research aimed to describe and analyze the food consumption of Amazonian riverside populations based on the food types consumed and reported by the families. METHODS: A cross-sectional study was carried out on the rural riverside population occupying part of the riverbank of Rio Negro, in Manaus County, North Brazil. This population can only be accessed by river. Random, systematic, stratified sampling was conducted on 287 households. A questionnaire about consumed food, socioeconomic conditions and food obtainment was applied. The analysis was performed in R software. Descriptive statistical analysis and log-binomial regression were carried out. RESULTS: It was observed that eating habits were mainly based on in natura (unprocessed) or minimally processed foods, according to the food classification system NOVA. Food diversity was low and the most consumed food types were coffee, flour and rice. The influence of small local markets, income and traditional practices on food intake based on food processing level was also observed. Thus, the chances of eating fish in locations with a small grocery shop were lower (p=0.009) and of eating chicken were higher (p≤0.001). The chances of consuming in natura or minimally processed foods among the literate population (p=0.041) with higher income (p≤0.001) were higher. The chances of eating processed foods were lower where fishing (p=0.007) and farming (p=0.009) were practiced. CONCLUSION: Based on these unexpected results, the present research highlights the food consumption of a riverside population and reduces the shortage of information about the largest traditional Amazonian population.
