RESUMO

METHODS: Retrospective cohort study with review of medical records of women assisted between 2015 and 2020. The variables were socio-demographic and SV characteristics, gestational age, reactions towards pregnancy and outcome. We compared outcome groups using the chi-square test, Fisher's exact test and the Kruskal-Wallis test. The significance level was 5%. RESULTS: We evaluated the medical records of 235 women, of which 153(65%) had undergone to abortion; 17(7.2%) had a spontaneous abortion; 19(8%) remained pregnant; 25(10.6%) had an abortion denied; and 21(8.9%) had been lost to follow-up. Out of the total number of women, 44(18.7%) were adolescents, 152(65.2%) were white and 201(88.5%) had an education ≥9 years. Women who remained pregnant had a known aggressor, disclosed the pregnancy (p < 0.001) and were more ambivalent (p < 0.001) than the other groups. Gestational age was higher in the denied abortion group than in the performed abortion group (p < 0.001). CONCLUSION: Feelings related to decision-making about abortion affected all groups, with differences. It is important to give women space to be heard, so they can make their own decisions.


Abortion care is possible in places with restrictive laws; however, women with more vulnerable characteristics did not seek the service. Legal restrictions interfere with women's decision-making about abortion and can promote inequality in gaining access to health services.

RESUMO

The discovery and development of effective novel compounds is paramount in oncology for improving cancer therapy. In this study, we developed a new derivative of spiroindolone (7',8'-Dimethoxy-1',3'-dimethyl-1,2,3',4'-tetrahydrospiro[indole-3,5'- pyrazolo[3,4-c]isoquinolin]-2-one) and evaluated its anticancer- and immunomodulatory potential in a vitro model of chronic leukemia. We utilized the chronic leukemia cell line K562, as well as non-cancerous peripheral blood mononuclear cells (PBMC) and Vero cells (kidney epithelium of Cercopithecus aethiops). We assessed the cytotoxicity of the compound using the MTT assay, and performed cell cycle assays to determine its impact on different stages of the cell cycle. To evaluate its antineoplastic activity, we conducted a colony formation test to measure the effect of the compound on the clonal growth of cancer cells. Furthermore, we evaluated the immunomodulatory activity of the compound by measuring the levels of pro and anti-inflammatory cytokines. The study findings demonstrate that the spiroindolone-derived compound exerted noteworthy cytotoxic effects against K562 cells, with an IC50 value of 25.27 µg/mL. Additionally, it was observed that the compound inhibited the clonal proliferation of K562 cells while displaying minimal toxicity to normal cells. The compound exhibited its antiproliferative activity by inducing G2/M cell cycle arrest, preventing the entry of K562 cells into mitosis. Notably, the compound demonstrated an immunomodulatory effect by upregulating the production of cytokines IL-6 and IL-12/23p40. In conclusion, the spiroindolone-derived compound evaluated in this study has demonstrated significant potential as a therapeutic agent for the treatment of chronic myeloid leukemia. Further investigations are warranted to explore its clinical applications.

RESUMO

Caralluma europaea (Guss.) is an important medicinal plant widely used in Morocco for various traditional purposes. Our work aimed to evaluate the phenolic composition, wound healing, antinociceptive, and anticancer activities of C. europaea extracts. Moreover, this study assessed the beneficial effect of C. europaea phytocompounds on the TRADD, cyclooxegenase-2, Wnt/ß-catenin, and tyrosine kinase signaling pathways. The wound healing effect of C. europaea formulations against skin burn was evaluated for 21 days. The cytotoxic effect of the C. europaea extracts was evaluated against human leukemic (K562 and HL60) and liver cancer cell lines (Huh-7) using the MTT test. All the phytoconstituents identified by UHPLC in the polyphenols were docked for their inhibitory power on protein casein kinase-1, glycogen synthase kinase-3-ß, cyclooxegenase-2, tyrosine kinase, and TRADD. Luteolin and kaempferol are the main compounds identified in C. europaea polyphenols. The group treated with polyphenols showed the greatest wound contractions and all tested extracts presented a significant antinociceptive effect. Polyphenols showed a remarkable antitumoral activity against the K562, HL60 and Huh-7 cell lines. Saponins exerted an important cytotoxic effect against the Huh-7 cell line, whereas no cytotoxicity was observed for the hydroethanolic and flavonoids extracts. Hesperetin and trimethoxyflavone presented the highest docking G-score on tyrosine kinase and cyclooxygenase, respectively.

RESUMO

Pregnant women are an important group to be monitored for infection due to the risk of transmitting infections to their babies. Both herpes simples virus (HSV) and Zika virus (ZIKV) are neurotropic viruses that can be transmitted congenitally. In this study, the prevalence and risk factors of HSV among Zika-positive and -negative pregnant women from Rio de Janeiro, Brazil, were evaluated and compared. About 167 serum samples included in our study were from pregnant women with ZIKV infection symptoms, who were attended to in different hospitals in Rio de Janeiro between November 2015 to February 2016. Blood samples collected from 167 pregnant women were used for this study. The presence of HSV antibodies and viremia were evaluated by commercial ELISA and quantitative real-time polymerase chain reaction analyses, respectively. The data obtained from medical records were statistically analyzed. The HSV-1 and HSV-2 prevalence among pregnant women was 80.2% and 12.5% for Zika-positive women and 84.5% and 5.6% for Zika-negative women, respectively. None of the pregnant women exhibited HSV viremia. Age, trimester of gestation, and skin color were associated with HSV-1 and HSV-2 prevalence among the groups studied. HSV-2 was more prevalent in Zika-positive pregnant women than in Zika-negative pregnant women, and this simultaneous infection should be better investigated in future studies.

RESUMO

Colorectal cancer (CRC) is one of the most common cancers in Latin America and the Caribbean, with the highest rates reported for Uruguay, Brazil and Argentina. We provide a global snapshot of the CRC patterns, how screening is performed, and compared/contrasted to the genetic profile of Lynch syndrome (LS) in the region. From the literature, we find that only nine (20%) of the Latin America and the Caribbean countries have developed guidelines for early detection of CRC, and also with a low adherence. We describe a genetic profile of LS, including a total of 2,685 suspected families, where confirmed LS ranged from 8% in Uruguay and Argentina to 60% in Peru. Among confirmed LS, path_MLH1 variants were most commonly identified in Peru (82%), Mexico (80%), Chile (60%), and path_MSH2/EPCAM variants were most frequently identified in Colombia (80%) and Argentina (47%). Path_MSH6 and path_PMS2 variants were less common, but they showed important presence in Brazil (15%) and Chile (10%), respectively. Important differences exist at identifying LS families in Latin American countries, where the spectrum of path_MLH1 and path_MSH2 variants are those most frequently identified. Our findings have an impact on the evaluation of the patients and their relatives at risk for LS, derived from the gene affected. Although the awareness of hereditary cancer and genetic testing has improved in the last decade, it is remains deficient, with 39%-80% of the families not being identified for LS among those who actually met both the clinical criteria for LS and showed MMR deficiency.

RESUMO

BACKGROUND: Zika Virus (ZIKV), member of Flaviviridae family and Flavivirus genus, has recently emerged as international public health emergency after its association with neonatal microcephaly cases. Clinical diagnosis hindrance involves symptom similarities produced by other arbovirus infections, therefore laboratory confirmation is of paramount importance. DISCUSSION: The most reliable test available is based on ZIKV RNA detection from body fluid samples. However, short viremia window periods and asymptomatic infections diminish the success rate for RT-PCR positivity. Beyond molecular detection, all serology tests in areas where other Flavivirus circulates proved to be a difficult task due to the broad range of cross-reactivity, especially with dengue pre-exposed individuals. CONCLUSION: Altogether, lack of serological diagnostic tools brings limitations to any retrospective evaluation. Those studies are central in the context of congenital infection that could occur asymptomatically and mask prevalence and risk rates.

RESUMO

This work reports the dating of a fossil human tooth and shell found at the archaeological site Toca do Enoque located in Serra das Confusões National Park (Piauí, Brazil). Many prehistoric paintings have been found at this site. An archaeological excavation unearthed three sepulchers with human skeletons and some shells. Two Brazilian laboratories, in Ribeirão Preto (USP) and Recife (UFPE), independently performed Electron Spin Resonance (ESR) measurements to date the tooth and the shell and obtain the equivalent dose received by each sample. The laboratories determined similar ages for the tooth and the shell (~4.8 kyBP). The results agreed with C-14 dating of the shell and other samples (charcoal) collected in the same sepulcher. Therefore, this work provides a valid inter-comparison of results by two independent ESR-dating laboratories and between two dating methods; i.e., C-14 and ESR, showing the validity of ESR dating for this range of ages.

RESUMO

BACKGROUND/AIMS: Cone beam computed tomography (CBCT), which represents an alternative to traditional computed tomography and magnetic resonance imaging, may be a useful instrument to study vocal tract physiology related to vocal exercises. This study aims to evaluate the applicability of CBCT to the assessment of variations in the vocal tract of healthy individuals before and after vocal exercises. METHODS: Voice recordings and CBCT images before and after vocal exercises performed by 3 speech-language pathologists without vocal complaints were collected and compared. Each participant performed 1 type of exercise, i.e., Finnish resonance tube technique, prolonged consonant "b" technique, or chewing technique. The analysis consisted of an acoustic analysis and tomographic imaging. RESULTS: Modifications of the vocal tract settings following vocal exercises were properly detected by CBCT, and changes in the acoustic parameters were, for the most part, compatible with the variations detected in image measurements. CONCLUSION: CBCT was shown to be capable of properly assessing the changes in vocal tract settings promoted by vocal exercises.

RESUMO

Stroke is a catastrophic complication of sickle cell anaemia (SCA) and is one of the leading causes of death in both adults and children with SCA. Evidence suggests that some genetic polymorphisms could be related to stroke development, but their association remains controversial. Here, we performed genotyping of five published single nucleotide polymorphisms, the α-thalassemia genotype, the G6PD A (-) variant deficiency, and the ß(S) haplotype in a large series of SCA patients with well-defined stroke phenotypes. Of 261 unrelated SCA patients included in the study, 67 (9.5 %) presented a documented, primary stroke event. Markers of haemolysis (red blood cell (RBC) counts, p = 0.023; reticulocyte counts, p = 0.003; haemoglobin (Hb) levels, p < 0.001; indirect bilirubin levels, p = 0.006; lactate dehydrogenase (LDH) levels, p = 0.001) were associated with stroke susceptibility. Genetically, only the ß(S) haplotype (odds ratio (OR) 2.9, 95 % confidence interval (CI) 1.56 to 4.31; p = 0.003) and the α(3.7kb)-thalassemia genotype (OR 0.31, 95 % CI 0.11 to 0. 83; p = 0.02) were associated with increased and decreased stroke risk, respectively. In multivariate analysis, the ß(S) haplotype was independently associated with stroke development (OR 2.26, 95 % CI 1.16 to 4.4; p = 0.016). Our findings suggest that only the ß(S) haplotypes and the α(3.7kb)-thalassemia genotype modulate the prevalence of stroke in our SCA population. Genetic heterogeneity among different populations may account for the irreproducibility amongst different studies.

RESUMO

OBJECTIVES: To analyze self-esteem, self-satisfaction with voice, and self-assessment with descriptive terms of one's own voice among Brazilian LGBTQIAPN+ people. STUDY DESIGN: Cross-sectional, observational, qualitative-quantitative study. METHODS: The study included any person who identified as Brazilian LGBTQIAPN+ and excluded those under 18 years old. Participants answered a sociodemographic questionnaire, the Rosenberg Self-Esteem Scale, and the Descriptive terms of one's own voice (which were analyzed with text processing techniques). The 10 terms most listed as positive or negative were selected for simple logistic regression associated with the Rosenberg Self-Esteem Scale. The alpha level of significance used in all analyses was 5%. RESULTS: The study considered the responses from 411 participants. It is noteworthy that 92.45% (n = 380) of the studied population identified as cisgender. Among the participants, 28 were classified as having unsatisfactory self-esteem, 208 as having average self-esteem, and 178 as having satisfactory self-esteem. Individuals with unsatisfactory scores described themselves using terms such as "high," "boring," "ugly," "unfriendly," and "masculine," while those with average scores used terms like "insecure," "nasal," "out of tune," and "high." Those with satisfactory scores associated themselves with terms such as "expressive," "sympathetic," "kind," "pleasant," and "stable." The terms "cheerful," "adequate," and "boring" significantly associated with the Rosenberg Self-Esteem Scale.score. CONCLUSION: LGBTQIAPN+ people with unsatisfactory self-esteem referred to their voices with negative descriptive terms, similar to people with average self-esteem, who often did not select any positive term. On the other hand, people with satisfactory self-esteem assessed their voices with positive descriptive terms and few negative adjectives. People with satisfactory scores are more likely to think that their voice is "cheerful" and less likely to consider it "adequate" or "boring" than people with unsatisfactory scores on the Rosenberg Self-Esteem Scale. The majority of participants were cisgender homosexual males, thus caution should be exercised in generalizing the data to the entire community.

RESUMO

Crataegus monogyna (C. monogyna) is a prominent plant used in Moroccan traditional medicine. This study investigated the phenolic composition and the anti-inflammatory, the hepatoprotective, and the anticancer activities of a hydroethanolic extract of C. monogyna leaves and stems. Ultra-high-performance liquid chromatography identified the phenolic profile. The in vitro anticancer activity was evaluated using the MTT assay on HL-60 and K-562 myeloleukemia cells and liver (Huh-7) cell lines. The anti-inflammatory effect was assessed in vivo using carrageenan-induced paw edema in rats. The hepatoprotective effect at 300 and 1000 mg/kg doses against the acetaminophen-induced hepatotoxicity on rats was studied for seven days. Additionally, molecular docking simulations were performed to evaluate the extract's inhibitory potential against key targets: lipoxygenase, cytochrome P450, tyrosine kinase, and TRADD. The extract exhibited significant cytotoxic activity against K-562 and HL-60 cells, but not against lung cancer cells (Huh-7 line). The 1000 mg/kg dose demonstrated the most potent anti-inflammatory effect, inhibiting edema by 99.10% after 6 h. C. monogyna extract displayed promising hepatoprotective properties. Procyanidin (-7.27 kcal/mol), quercetin (-8.102 kcal/mol), and catechin (-9.037 kcal/mol) were identified as the most active molecules against lipoxygenase, cytochrome P450, and tyrosine kinase, respectively. These findings highlight the untapped potential of C. monogyna for further exploration in treating liver damage, inflammation, and leukemia.

RESUMO

Nanocapsules provide selective delivery and increase the bioavailability of bioactive compounds. In this study, we examined the anticancer and immunomodulatory potential of Fridericia chica (crajiru) extract encapsulated in nanocapsules targeting myeloid leukemias. Nanocapsules containing crajiru (nanocapsules-CRJ) were prepared via interfacial polymer deposition and solvent displacement. Size and polydispersity were measured by dynamic light scattering. Biological assays were performed on leukemia cell lines HL60 and K562 and on non-cancerous Vero cells and human PBMC. The anticancer activity was evaluated using cytotoxicity and clonogenic assays, while the immunomodulatory activity was evaluated by measuring the levels of pro- and anti-inflammatory cytokines in PBMC supernatants treated with concentrations of nanocapsules-CRJ. Nanocapsules-CRJ exhibited significant cytotoxic activity against HL60 and K562 cells at concentrations ranging from 0.75 to 50 µg/mL, with the greatest reductions in cell viability observed at 50 µg/mL (p < 0.001 for HL60; p < 0.01 for K562), while not affecting non-cancerous Vero cells and human PBMCs. At concentrations of 25 µg/mL and 50 µg/mL, nanocapsules-CRJ reduced the formation of HL60 and K562 colonies by more than 90% (p < 0.0001). Additionally, at a concentration of 12 µg/mL, nanocapsules-CRJ induced the production of the cytokines IL-6 (p = 0.0002), IL-10 (p = 0.0005), IL-12 (p = 0.001), and TNF-α (p = 0.005), indicating their immunomodulatory potential. These findings suggest that nanocapsules-CRJ hold promise as a potential therapeutic agent with both cytotoxic and immunomodulatory properties.

RESUMO

INTRODUCTION: Combining mechanical vibration stimulation with resistance training to improve neuromuscular performance is a method that has gained popularity in the field of sports sciences. PURPOSE: To evaluate the immediate and mid-term effects of mechanical vibration stimulation (G-Life NL3000) of the larynx associated to vocal exercises. METHOD: Fourteen professional voice users divided into: Experimental Group - Seven participants who performed a 20-minute exercise protocol with humming applying mechanical vibration stimulation (G-Life NL3000) of the larynx once a day for 30 days; Control Group - Seven participants who performed only the 20-minute exercise protocol with humming. For comparison purposes, the evaluation was carried out pre-stimulation, immediately after simulation (post) and 30 days after stimulation (late-post). RESULTS: The Experimental Group showed a statistically significant progress in the post-immediate evaluation and in the post-treatment evaluation for maximum phonation time (*P = < 0.001), Jitter (*P = 0.008), Shimmer (*P = 0.005), noise-to-harmonics ratio (*P = 0.005). In the GRBASI scale, the Experimental Group showed significant results in the post-treatment evaluation for Grade (*P = 0.005), Roughness (*P = 0.008), Breathiness (*P = 0.018) and Instability (*P = 0.018). A self-perception voice questionnaire showed better voice quality (*P= 0.031) and easier phonation (*P = 0.005) in the Experimental Group. CONCLUSION: Mechanical vibration stimulation of the larynx associated to humming produced positive changes in the vocal pattern and significantly improvement in short and mid-term vocal quality for participants in this study.

RESUMO

In recent years dengue has become a rapidly growing public health problem worldwide, however, the availability of accurate and affordable diagnostic immunoassays is limited, partly due to the difficulty of producing large quantities of purified antigen. Non-structural protein 1 (NS1) has shown to be a good candidate for inclusion in diagnostic assays and for serosurveys, particularly in endemic countries as a prerequisite for vaccination. In this work the NS1 antigen derived from dengue virus type-1 (DENV1) was expressed in HEK293-T cells and purified by affinity chromatography. The recombinant protein was recovered properly folded as dimers, highly purified and with good yield (1.5 mg/L). It was applied as a serological probe in an indirect ELISA developed in this work to detect human IgG antibodies. Preliminary comparative performance values of 81.1% sensitivity and 83.0% specificity of the developed and preliminary validated iELISA, relative to a commercial kit were obtained, suggesting that the purified recombinant DENV1 NS1 antigen is suitable to detect IgG antibodies, indicative of past DENV infection.

RESUMO

OBJECTIVE: To assess the loss to follow-up after emergency care and during 6-months of outpatient follow-up, and the associated variables, among adolescent sexual violence survivors. METHODS: This is a retrospective study with review of the medical records of 521 females, aged 10 to 18 years, who received emergency care in a referral service in São Paulo, Brazil. The variables were sociodemographic; personal history; characteristics of abuse, disclosure, and reactions triggered after abuse (physical and mental disorders as well as social changes), psychotropic prescription needs, and moment of abandonment: after emergency care and before completing 6 months of outpatient follow-up. To compare groups of patients lost to follow-up at each time point, we used the Chi-square and Fisher exact tests followed by multiple logistic regression with stepwise criterion for selection of associated variables. We calculated the odds ratio with confidence interval (OR, CI 95%). The level of significance adopted was 5%. RESULTS: A total of 249/521 (47.7%) adolescents discontinued follow-up, 184 (35.3%) after emergency care and 65 (12.4%) before completing outpatient follow-up. The variables of living with a partner (OR = 5.94 [CI 95%; 2.49-14.20]); not having a religion (OR = 2.38 [CI 95%;1.29-4.38)]), having a Catholic religion [OR = 2.11 (CI 95%; 1.17-3.78)]; and not disclosing the abuse [OR = 2.07 (CI 95%; 1.25-3.44)] were associated with loss to follow-up after emergency care. Not needing mental disorder care (OR = 2.72 [CI 95%; 1.36-5.46]) or social support (OR = 2.33 [CI 95%; 1.09-4.99]) were directly associated with loss to outpatient follow-up. CONCLUSION: Measures to improve adherence to follow-up should be aimed at adolescents who live with a partner and those who do not tell anyone about the violence.


OBJETIVOS: Avaliar a perda de seguimento de adolescentes vítimas de violência sexual após o atendimento de emergência, durante o seguimento ambulatorial e as variáveis associadas. MéTODOS: Estudo retrospectivo com a revisão de prontuários de 521 mulheres de 10 a 18 anos, que buscaram atendimento de emergência em um serviço de referência em São Paulo, Brasil. As variáveis foram sociodemográficas; antecedentes pessoais; características do abuso, atitude de revelação e reações desencadeadas após o abuso (distúrbios físicos, mentais e mudanças sociais), necessidades de prescrição de psicotrópicos e momento do abandono: após atendimento de emergência e antes de completar 6 meses de seguimento ambulatorial. Para comparar os grupos de perda de seguimento em cada momento, foram utilizados os testes do qui-quadrado e exato de Fisher, seguidos de regressão logística múltipla com critério stepwise para seleção das variáveis associadas. Calculamos a razão de probabilidade com intervalo de confiança (RP, IC 95%). O nível de significância adotado foi de 5%. RESULTADOS: Um total de 249 (47,7%) das adolescentes descontinuaram o acompanhamento, 184 (35.3%) após o atendimento de emergência e 65 (12.4%) antes de completar o seguimento ambulatorial. As variáveis de viver com companheiro [RP = 5,94 (IC 95%; 2,49­14,20]; não ter religião [RP = 2,38 (IC 95%;1,29­4,38)], ter religião católica [RP = 2,11 (IC 95%; 1,17­3,78)] e não revelar o abuso [RP = 2,07 (IC 95%; 1,25­3,44)] foram associadas à perda de seguimento após o atendimento de emergência. Não necessitar de cuidados de saúde mental (RP = 2,72 [IC 95%; 1,36­5,46]) ou apoio social (RP = 2,33 [IC 95%; 1,09­4,99]) foram as variáveis associadas à perda do seguimento ambulatorial. CONCLUSãO: Medidas para melhorar a adesão ao seguimento devem ser direcionadas às adolescentes que vivem com parceiro e às que não revelam a violência sofrida.

RESUMO

Culex Flavivirus (CxFV) is a classical insect-specific virus, which has aroused interest after the first indication that it can produce in nature superinfection exclusion of viruses of medical interest such as West Nile. Despite the detection of CxFV in different regions, CxFV ecology and the influence of co-circulation of arboviruses remains poorly understood. Therefore, our primary goals are to observe the occurrence of CxFV infection in mosquitoes trapped in an urban area of Rio de Janeiro, Brazil, characterize the virus circulating, and provide isolates. A prospective study was carried out for eight months on the campus of the Federal University of Rio de Janeiro, trapping adult mosquitoes. The CxFV minimum infection rates were determined in this period, and the virus isolation process is fully described. Samples from this study were grouped into genotype 2, along with CxFV sequences from Latin America and Africa.

RESUMO

OBJECTIVE: To compare the sexual violence suffered by women in early and late adolescence, the reactions triggered after the aggression, and the care provided. METHODS: A retrospective study in which we reviewed the medical records of 521 female adolescents treated by a multidisciplinary team at a reference hospital in the city of Campinas, state of São Paulo, Brazil. We analyzed sociodemographic variables, and those pertainin to the characteristics of the episodes of violence, the emergency care, and the physical and psychological reactions observed during the follow-up. For the analysis, the sample was divided into groups of early (10 to 14 years) and late (15 to 18 years) adolescence. We used the Chi-squared/Fisher Exact, Mann-Whitney, and Kruskal-Wallis tests to compare the groups; the level of significance adopted was 5%. RESULTS: The early group (n = 242) contained more adolescents who were enrolled in school (p < 0.001), suffered more daytime aggressions (p = 0.031), in their residences (p < 0.001), by an aggressor with whom they were acquainted (p < 0.001), had greater need of legal protection (p = 0.001), and took longer to seek care (p = 0.048). Feelings of guilt, shame, and the perception of violence were similar between the groups. In the late group (n = 279), there was greater consumption of alcohol during the aggression (p = 0,005); they received significantly more prophylaxis treatments; reported more physical symptoms (p = 0.033), sleep disorders (p = 0.003), symptoms of anxiety (p = 0.045), and feelings of anguish (p = 0.011); and had more prescriptions of psychotropics (p = 0.005). Only 52% completed the 6-month follow-up, with no differences between the groups. CONCLUSION: The age groups showed differences in the characteristics of the episodes of violence; early adolescents took longer to seek help, and the late group presented more intense symptoms and psychological worsening during the follow-up. Measures of prevention and specific care aimed at this population are needed.


OBJETIVO: Comparar a violência sexual sofrida por vítimas no início e no final da adolescência, as reações desencadeadas após a agressão, e o cuidado de saúde dispensado. MéTODOS: Estudo retrospectivo, em que foram revisados os prontuários de 521 mulheres adolescentes atendidas por equipe multiprofissional em hospital de referência em Campinas, São Paulo, Brasil. As variáveis foram sociodemográficas, e aquelas relativas às características da violência, ao atendimento de emergência, e às reações físicas e psicológicas observadas durante o seguimento nos grupos de adolescentes de idade precoce (10a 14 anos) e tardia (15 a 18 anos). Utilizamos os testes do Qui-quadrado/Exato de Fisher, Mann-Whitney e Kruskal-Wallis para comparar os grupos; adotamos o nível de significância de 5%. RESULTADOS: O grupo precoce (n = 242) continha maior número de estudantes (p < 0,001), que sofreram mais agressões diurnas (p = 0,031), em suas residências (p < 0,001), por agressor conhecido (p < 0,001), tiveram maior necessidade de proteção legal (p = 0,001), e demoraram mais a procurar atendimento (p = 0,048). Sentimentos de culpa, vergonha e a percepção da violência foram similares entre os grupos. No grupo tardio (n = 279) houve maior consumo de álcool durante a agressão (p = 0,005); as adolescentes receberam significativamente mais tratamentos de profilaxia; relataram mais sintomas físicos (p = 0,033), distúrbios do sono (p = 0,003), sintomas de ansiedade (p = 0,045), e sentimentos de angústia (p = 0,011); e receberam mais prescrições de psicotrópicos (p = 0,005). Apenas 52% completaram o seguimento de 6 meses, sem diferenças entre os grupos. CONCLUSãO: Os grupos apresentaram diferenças nas características da violência; as adolescentes precoces chegaram mais tardiamente ao serviço, e o grupo tardio apresentou maior sintomatologia e piora psicológica no seguimento. São necessárias medidas de prevenção e cuidados específicos voltados a essa população.

RESUMO

The objective of this study was to investigate nonsuicidal self-injury (NSSI) in graduates and correlate NSSI with sociodemographic profile, suicidal behavior, and prior mental health disorders. The study is part of a larger survey investigating sociodemographic profile, quality of life and mental health in undergraduates from one of Brazil´s largest universities. A bespoke questionnaire was devised about NSSI based on the DSM5 diagnostic criteria. The data were analyzed using the statistical analysis package SPSS. A total of 6.906 university students took part in the study. Regarding NSSI, 17.8% of students reported at least one episode in their lifetime, and 35% reported age at NSSI onset of 14-16 years. Self-injurious behavior was associated with female gender, self-reported black skin color, dissatisfaction with the chosen course, history of bullying and prior mental disorder. There was a ten times greater risk of suicidal behavior among self-injurers and this risk was higher still for recurrent NSSI.

RESUMO

Dysbiosis is recognized as a new cardiovascular disease (CVD) risk factor in hemodialysis (HD) patients because it is linked to increased generation in the gut of uremic toxins such as trimethylamine N-Oxide (TMAO) from dietary precursors (choline, betaine, or L-carnitine). Nutritional strategies have been proposed to modulate the gut microbiota and reduce the production of these toxins. This study aimed to evaluate the effect of amylose-resistant starch (RS) supplementation on TMAO plasma levels in HD patients.We conducted a randomized, double-blind, placebo-controlled trial (NCT02706808) with patients undergoing HD enrolled in a previous pilot study. The participants were allocated to RS or placebo groups to receive 16 g/d of RS or placebo for 4 weeks. Plasma TMAO, choline, and betaine levels were measured with LC-MS/MS. Fecal microbiome composition was evaluated by 16S ribosomal RNA sequencing, followed by a search for TMA-associated taxa. Anthropometric, routine biochemical parameters, and food intake were evaluated.Twenty-five participants finished the study, 13 in the RS group, and 12 in the placebo group. RS supplementation did not reduce TMAO plasma levels. Moreover, no significant alterations were observed in choline, betaine, anthropometric, biochemical parameters, or food intake in both groups. Likewise, RS was not found to exert any influence on the proportion of potential TMA-producing bacterial taxa in fecal matter.RS supplementation did not influence plasma TMAO, choline, betaine, or fecal taxa potentially linked to TMAO. Thus, RS does not seem to modify the TMA-associated bacterial taxa, precursors of TMAO.Supplemental data for this article is available online at https://doi.org/10.1080/07315724.2021.1967814 .
