Birth in Brazil II: a postpartum maternal, paternal and child health research protocol. / Nascer no Brasil II: protocolo de investigação da saúde materna, paterna e da criança no pós-parto.

Pregnancy, parturition and birth bring major changes to the lives of mothers and fathers. This article presents a research protocol for estimating the prevalence of postpartum mental health outcomes in mothers and fathers, abuse and satisfaction in delivery/abortion care, and the correlations between them and socioeconomic, obstetric, and child health factors. As a 2-component research, it consists of a prospective cohort study with all postpartum women interviewed in the 465 maternity hospitals included at the Birth in Brazil II baseline survey conducted from 2021 to 2023, and a cross-sectional study with the newborns' fathers/partners. Interviews will be conducted via telephone or self-completion link sent by WhatsApp with the mother at 2 and 4 months after delivery/abortion. Partners will be approached three months after birth (excluding abortions, stillbirths and newborn death) using the telephone number informed by the mother at the maternity ward. Postpartum women will be inquired about symptoms of depression, anxiety and post-traumatic stress disorder, abuse during maternity care and quality of the mother-newborn bond. Maternal and neonatal morbidity, use of postnatal services, and satisfaction with maternity care are also investigated. Fathers will be asked to report on symptoms of depression and anxiety, and the quality of the relationship with the partner and the newborn. The information collected in this research stage may help to plan and improve care aimed at the postpartum health of the mother-father-child triad.

Sudden infant death syndrome - a community intervention project.

OBJECTIVE: To capacitate pregnant women to comply with measures designed to prevent sudden infant death syndrome. METHODS: A quasi-experimental study was conducted before and after the intervention that included pregnant women attending the Course of Preparation for Childbirth and Parenthood of Health Centers Cluster. Six training sessions were given in the context of preventing this syndrome. Three questionnaires were applied, one to evaluate the knowledge of pregnant women before classes, other was submitted after the sessions, and another, one month after the birth of the babies, to identify what skills were acquired and which were practiced. RESULTS: Among 77 studied pregnant women, 70 answered pre-session questionnaire and the proportion of correct answers varied from from 60.0% to 84.3%. After the intervention, 64 women answered the questionnaire and the proportion of correct answers varied between 79.7% and 100% . Prior to the intervention, the most wrong answers were related to the role of smoking as a risk factor for sudden infant death syndrome and to the use of pacifiers as a protective measure. After the sessions, all women answered correctly to the questions concerning where the baby should sleep and the safest way to lay the baby in the cradle. CONCLUSIONS: Health education with the aim of establishing measures may have a significant impact in terms of care delivery and mortality rate caused by sudden infant death syndrome.

Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia in Children: A Retrospective Cohort Study at a Pediatric Oncology Center.

Background and objective Philadelphia chromosome-positive acute lymphoblastic leukemia (ALL Ph+) is quite rare among pediatric patients. Its management has undergone significant changes in the past few years, leading to some variability in how it is approached. At the Portuguese Oncology Institute of Porto (IPOP), a tertiary oncological center, the standard of care has been aligned with the guidelines proposed by the European intergroup study of post-induction treatment of ALL Ph+ (EsPhALL). In this study, we aimed to examine the experience and outcomes related to the treatment of pediatric patients with ALL Ph+ at IPOP. Methods This retrospective cohort study involved pediatric patients diagnosed with ALL Ph+ at IPOP between January 2008 and December 2022 and analyzed their outcomes. Results A total of 14 patients were included. IKFZ1 was altered in five patients (out of nine in whom it was searched). Five patients were treated according to EsPhALL 2004, which involved starting imatinib later in a discontinuous manner [resulting in both five-year overall survival (OS) and progression-free survival (PFS) of 60%]. The EsPhALL 2010 (preconizing a continuous imatinib regimen instead) was employed in three patients, with a five-year OS and PFS of 66.7%. All children mentioned above received cranial irradiation therapy (CRT). Finally, six were treated according to the EsPhALL 2015, which stopped including CRT in its backbone. The five-year OS was 100%, whereas every patient progressed with an increase in BCR::ABL1 levels greater than 1-log. Moreover, until 2015, all patients had been recommended to undergo allogeneic hematopoietic stem cell transplantation (alloHSCT). However, since 2015, alloHSCT has been exclusively reserved for relapsed/refractory (R/R) disease or poor responders with positive measurable residual disease (MRD). In total, alloHSCT was performed in nine patients. Conclusions Although initially associated with a poor prognosis, the ALL Ph+ paradigm is drastically shifting. Further studies will hopefully clarify the outcomes in this population and help understand the role of central nervous system (CNS) prophylaxis, alloHSCT, and MRD quantification.

Increased consumption of ultra-processed foods during pregnancy is associated with sociodemographic, behavioral, and obstetric factors: A cohort study.

A diet based on ultra-processed food (UPF) does not meet nutritional needs, especially during pregnancy. The aim of this study is to assess the change in UPF consumption from preconception to pregnancy and associated factors. Our hypothesis is that women tend to adopt a healthier eating pattern during pregnancy, decreasing the intake of UPF and increasing the intake of unprocessed/minimally processed foods. A prospective cohort study with 326 participants was carried out from 2016 to 2019 in 2 health units in Rio de Janeiro, Brazil. Pregestational food consumption assessed using the food frequency questionnaire in the prenatal interview in women up to 20 gestational weeks and gestational consumption in the interview 2 months after delivery. Food items classified according to the NOVA system. For the mean variation from preconception to gestational UPF consumption, we used the generalized estimating equations model with linear distribution. Control of confounding variables was based on the literature on factors associated with UPF consumption, using a 3-level hierarchical model. The proportion of UPF energy consumption was 28.9% in preconception and 33% during pregnancy. Older and more educated women had a lower mean variation in the consumption of UPF during the pregnancy. A higher average consumption of UPF observed among women physically inactive before pregnancy, who smoked during pregnancy, were multiparous, and with had a low pregestational weight. These results reflect similar behavior to that of the general population, aggravated by a significant increase during pregnancy. However, older and more educated women and those with healthy behaviors showed lower UPF intake in pregnancy.

RESUMO Objetivo: Capacitar as grávidas para o cumprimento de medidas de prevenção da síndrome de morte súbita do lactente. Métodos: Realizou-se um estudo quase-experimental pré- e pós-intervenção que integrou as grávidas que frequentavam o Curso de Preparação para o Parto e Parentalidade do Agrupamento de Centros de Saúde. Foram ministradas seis sessões formativas no âmbito da prevenção desta síndrome. Três questionários foram aplicados, um para avaliar os conhecimentos das gestantes antes das aulas, outro foi submetido após as sessões, e outro, um mês após o nascimento dos bebês para identificar que conhecimentos foram adquiridos e quais foram praticados. Resultados: Da amostra de 77 grávidas, relativamente ao questionário pré-sessão (n=70), obteve-se uma proporção de respostas corretas entre 60,0-84,3%. Posteriormente à intervenção (n=64), verificou-se um incremento dos conhecimentos com 79,7-100% de acertos. Previamente à intervenção, as respostas mais erradas às questões eram inerentes ao papel do tabagismo como fator de risco para síndrome de morte súbita do lactente e ao uso da chupeta como medida protetora. Após as sessões, todas as mulheres responderam corretamente às questões relativas ao local onde o bebê deve dormir e à forma mais segura de colocar o bebê no berço. Conclusões: Este projeto demonstrou que a educação para a saúde com o intuito de instituir medidas pode ter um impacto significativo em termos de prestação de cuidados e taxa de mortalidade por síndrome de morte súbita do lactente.

SARS-CoV-2 decreases malaria severity in co-infected rodent models.

Coronavirus disease 2019 (COVID-19) and malaria, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Plasmodium parasites, respectively, share geographical distribution in regions where the latter disease is endemic, leading to the emergence of co-infections between the two pathogens. Thus far, epidemiologic studies and case reports have yielded insufficient data on the reciprocal impact of the two pathogens on either infection and related diseases. We established novel co-infection models to address this issue experimentally, employing either human angiotensin-converting enzyme 2 (hACE2)-expressing or wild-type mice, in combination with human- or mouse-infective variants of SARS-CoV-2, and the P. berghei rodent malaria parasite. We now show that a primary infection by a viral variant that causes a severe disease phenotype partially impairs a subsequent liver infection by the malaria parasite. Additionally, exposure to an attenuated viral variant modulates subsequent immune responses and provides protection from severe malaria-associated outcomes when a blood stage P. berghei infection was established. Our findings unveil a hitherto unknown host-mediated virus-parasite interaction that could have relevant implications for disease management and control in malaria-endemic regions. This work may contribute to the development of other models of concomitant infection between Plasmodium and respiratory viruses, expediting further research on co-infections that lead to complex disease presentations.

Transcriptomic and physiological shade avoidance responses in potato (Solanum tuberosum) plants.

Plants detect competitors in shaded environments by perceiving a reduction in photosynthetically active radiation (PAR) and the reduction between the red and far-red light (R:FR) ratio and blue photons. These light signals are detected by phytochromes and cryptochromes, which trigger shade avoidance responses such as shoot and petiole elongation and lead to increased susceptibility to pathogen attack. We studied morphological, anatomical, and photosynthesis differences in potato plants (Solanum tuberosum var. Spunta) exposed to sunlight or simulated shade in a greenhouse. We found that simulated shade strongly induced stem and internode elongation with a higher production of free auxin in stems and a lower production of tubers. The mesophyll thickness of the upper leaves of plants grown in simulated shade was lower, but the epidermis was wider compared with the leaves of plants cultivated in sunlight. In addition, the photosynthesis rate was lower in the upper leaves exposed to nonsaturated irradiances and higher in the basal leaves at saturated irradiances compared with control plants. RNA-seq analysis showed that 146 and 155 genes were up- and downregulated by shade, respectively. By quantitative reverse transcription polymerase chain reaction, we confirmed that FLOWERING LOCUS T (FT), WRKY-like, and PAR1b were induced, while FLAVONOL 4-SULFOTRANSFERASE was repressed under shade. In shaded plants, leaves and tubers were more susceptible to the necrotrophic fungus Botrytis cinerea attack. Overall, our work demonstrates configurational changes between growth and defense decisions in potato plants cultivated in simulated shade.

Factors associated with ultra-processed foods consumption in a cohort of Brazilian pregnant women.

Nutrition during pregnancy is essential for the health of the pregnant woman, the development of the fetus, and the prevention of complications related to pregnancy and the postpartum period. This study described the factors associated with high consumption of ultra-processed foods among pregnant women. This prospective cohort study was performed from February 2016 to November 2019 in two health units in the city of Rio de Janeiro, Brazil, with data from 344 pregnant women. The first interview was conducted in the prenatal visit at less than 20 gestational weeks, the second at 34 gestational weeks, and the third at two months postpartum. Diet was assessed in the last interview using a food frequency questionnaire, and food items were classified according to NOVA. The percentage of ultra-processed foods consumption was estimated by tertile distribution, and the third tertile represented the highest consumption. Based on the hierarchical analysis model, the associations between ultra-processed foods consumption and sociodemographic, reproductive health, pregestational, behavioral, and pregnancy variables were assessed using a multinomial logistic regression model. Older women had lower ultra-processed foods consumption (OR = 0.33; 95%CI: 0.15-0.71). Few years of schooling (up to 7 years; OR = 5.58; 95%CI: 1.62-19.23), history of a previous childbirth (OR = 2.48; 95%CI: 1.22-5.04), history of two or more previous childbirths (OR = 7.53; 95%CI: 3.02-18.76), and no history of regular physical activity before pregnancy (OR = 2.40; 95%CI: 1.31-4.38) were risk factors. The identification of risk and protection factors allows for the establishment of control measures and encouragement of healthy practices during prenatal care.

Cognitive impairment in Neuromyelitis Optica Spectrum Disorder: A retrospective study using the Brief International cognitive Assessment for Multiple Sclerosis (BICAMS).

BACKGROUND: Neuromyelitis Optica Spectrum Disorder (NMOSD) is an inflammatory disease of the central nervous system. The study aimed to characterize the neuropsychological profile of NMOSD by comparing them with multiple sclerosis (MS) patients and healthy controls. METHOD: Sixty-four participants were included:19 NMOSD, 27 MS, and 18 healthy controls. The neuropsychological protocol included the Portuguese version of Montreal Cognitive Assessment, the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS), Verbal Fluency (phonemic and semantic), the Hospital Anxiety and Depression Scale, and the Expanded Disability Status Scale for clinical groups. RESULTS: NMOSD patients had significant lower cognitive performance when compared to HC mainly in information processing speed, concentration, language processing, and in executive functions (cognitive flexibility, sustained, and divided attention). No significant differences were observed between NMOSD and MS patients. Three predictors for cognitive impairment, according to BICAMS criteria, were found: depression, disease duration, and the level of disability. CONCLUSION: The neuropsychological profile found in the present study for NMOSD is consistent with the previous findings. Information regarding the predictors of cognitive impairment in both diseases and their different associations are important for future research and for guiding interventions more suitable for the neuropsychological needs of affected patients.

AtBBX29 integrates photomorphogenesis and defense responses in Arabidopsis.

Light is an environmental signal that modulates plant defenses against attackers. Recent research has focused on the effects of light on defense hormone signaling; however, the connections between light signaling pathways and the biosynthesis of specialized metabolites involved in plant defense have been relatively unexplored. Here, we show that Arabidopsis BBX29, a protein that belongs to the B-Box transcription factor (TF) family, integrates photomorphogenic signaling with defense responses by promoting flavonoid, sinapate and glucosinolate accumulation in Arabidopsis leaves. AtBBX29 transcript levels were up regulated by light, through photoreceptor signaling pathways. Genetic evidence indicated that AtBBX29 up-regulates MYB12 gene expression, a TF known to induce genes related to flavonoid biosynthesis in a light-dependent manner, and MYB34 and MYB51, which encode TFs involved in the regulation of glucosinolate biosynthesis. Thus, bbx29 knockout mutants displayed low expression levels of key genes of the flavonoid biosynthetic pathway, and the opposite was true in BBX29 overexpression lines. In agreement with the transcriptomic data, bbx29 mutant plants accumulated lower levels of kaempferol glucosides, sinapoyl malate, indol-3-ylmethyl glucosinolate (I3M), 4-methylsulfinylbutyl glucosinolate (4MSOB) and 3-methylthiopropyl glucosinolate (3MSP) in rosette leaves compared to the wild-type, and showed increased susceptibility to the necrotrophic fungus Botrytis cinerea and to the herbivore Spodoptera frugiperda. In contrast, BBX29 overexpressing plants displayed increased resistance to both attackers. In addition, we found that AtBBX29 plays an important role in mediating the effects of ultraviolet-B (UV-B) radiation on plant defense against B. cinerea. Taken together, these results suggest that AtBBX29 orchestrates the accumulation of specific light-induced metabolites and regulates Arabidopsis resistance against pathogens and herbivores.

Onychomatricoma on the fourth toenail: A rare tumor in a rare localization.

Onychomatricoma is a rare benign tumor of the nail matrix, characterized by finger-like projections that invade the nail plate. The fingernails of Caucasian women are most commonly affected. Because this tumor can easily mimic other more prevalent ungual diseases, it is crucial to be acquainted with its characteristic clinical and histopathologic features. The authors present a case of a 40-year-old man with an onychomatrichoma in the fourth left toenail, which was initially misdiagnosed and treated as onychomycosis.

A nutrição durante a gravidez é essencial para a saúde da gestante, o desenvolvimento do bebê e a prevenção de complicações relacionadas à gravidez e ao pós-parto. Este estudo descreveu os fatores associados ao alto consumo de alimentos ultraprocessados entre gestantes. Trata-se de uma coorte prospectiva realizada de fevereiro de 2016 a novembro de 2019, em duas unidades de saúde do Município do Rio de Janeiro, Brasil, que analisou dados de 344 gestantes. A primeira entrevista foi realizada na consulta pré-natal com menos de 20 semanas de gestação, a segunda com 34 semanas de gestação e a terceira dois meses após o parto. A dieta foi avaliada na última entrevista por meio de um questionário de frequência alimentar e os itens alimentares foram classificados de acordo com a classificação NOVA. O percentual de consumo de alimentos ultraprocessados foi calculado em tercis de distribuição, dos quais o terceiro tercil representou o maior consumo. Com base no modelo de análise hierárquica, as associações entre o consumo de alimentos ultraprocessados e variáveis sociodemográficas, de saúde reprodutiva, pré-gestacionais, comportamentais e gestacionais foram investigadas usando um modelo de regressão logística multinomial. Mulheres mais velhas apresentaram menor consumo de alimentos ultraprocessados (OR = 0,33; IC95%: 0,15-0,71). Os fatores de risco foram baixa escolaridade (até sete anos; OR = 5,58; IC95%: 1,62-19,23), histórico de parto anterior (OR = 2,48; IC95%: 1,22-5,04), histórico de dois ou mais partos anteriores (OR = 7,53; IC95%: 3,02-18,76) e ausência de histórico de atividade física regular antes da gestação (OR = 2,40; IC95%: 1,31-4,38). A identificação de fatores de risco e proteção permite o estabelecimento de medidas de controle e o incentivo a práticas saudáveis durante o pré-natal.

La nutrición durante el embarazo es esencial para la salud de la futura madre, el desarrollo del bebé y la prevención de complicaciones relacionadas con el embarazo y el posparto. Este estudio describió los factores asociados con el alto consumo de alimentos ultraprocesados entre las mujeres embarazadas. Se trata de una cohorte prospectiva realizada entre febrero de 2016 y noviembre de 2019, en dos unidades de salud de la ciudad de Río de Janeiro, Brasil, que analizó datos de 344 gestantes. La primera entrevista se realizó en la visita prenatal a las 20 semanas de gestación, la segunda a las 34 semanas de gestación y la tercera dos meses después del parto. La dieta se evaluó en la última entrevista mediante un cuestionario de frecuencia de alimentos y los alimentos se clasificaron de acuerdo con la clasificación NOVA. El porcentaje de consumo de alimentos ultraprocesados se calculó en terciles de distribución, de los cuales el tercer tercil representó el mayor consumo. Con base en el modelo de análisis jerárquico, se investigaron las asociaciones entre el consumo de alimentos ultraprocesados y las variables sociodemográficas, de salud reproductiva, previas al embarazo, conductuales y gestacionales mediante un modelo de regresión logística multinomial. Las mujeres mayores presentaron menor consumo de alimentos ultraprocesados (OR = 0,33; IC95%: 0,15-0,71). Los factores de riesgo fueron bajo nivel educativo (hasta siete años; OR = 5,58; IC95%: 1,62-19,23), antecedentes de parto previo (OR = 2,48; IC95%: 1,22-5,04), antecedentes de dos o más partos previos (OR = 7,53; IC95%: 3,02-18,76) y sin antecedentes de actividad física regular antes del embarazo (OR = 2,40; IC95%: 1,31-4,38). La identificación de factores de riesgo y protección permite el establecimiento de medidas de control y el fomento de prácticas saludables durante la atención prenatal.

Myopericytoma presenting as a painful dark subungual discoloration.

Myopericytoma is an uncommon benign neoplasm that arises from the perivascular myoid cells. It typically presents as a painless well-circumscribed cutaneous or soft-tissue nodule, most commonly on the extremities of adults. Histologically, it is characterized by spindle-shaped myoid-appearing cells with a concentric arrangement in vessel walls, that are immunoreactive to alpha-smooth muscle actin and often for h-caldesmon, but negative for other smooth muscle markers. Herein, we present an unusual case of a painful subungual myopericytoma presenting as a dark subungual discoloration.

Nail Surgery: General Principles, Fundamental Techniques, and Practical Applications.

Despite being an integral part of dermatologic surgery, nail surgery is infrequently performed in daily practice. Indeed, it is frequently considered difficult, time-consuming, and the results take a long time to be observed. Nonetheless, nail pathology is a frequent cause of dermatology consultation, so dermatologists should be familiar with its diagnosis and therapeutic approach, which often involves surgical procedures. This article provides a review of nail surgery, focusing on the anatomy of this region, anesthesia of the ungual apparatus, common surgical techniques, reconstruction of defects in these locations, and a general approach to the most frequently encountered conditions in clinical practice.
