Abstract Visceral leishmaniasis (VL) is an infectious disease predominant in countries located in the tropics. The prediction of occurrence of infectious diseases through epidemiologic modeling has revealed to be an important tool in the understanding of its occurrence dynamic. The objective of this study was to develop a forecasting model for the incidence of VL in Maranhão using the Seasonal Autoregressive Integrated Moving Average model (SARIMA). We collected monthly data regarding VL cases from the National Disease Notification System (SINAN) corresponding to the period between 2001 and 2018. The Box-Jenkins method was applied in order to adjust a SARIMA prediction model for VL general incidence and by sex (male or female) for the period between January 2019 and December 2013. For 216 months of this time series, 10,431 cases of VL were notified in Maranhão, with an average of 579 cases per year. With regard to age range, there was a higher incidence among the pediatric public (0 to 14 years of age). There was a predominance in male cases, 6437 (61.71%). The Box-Pierce test figures for overall, male and female genders supported by the results of the Ljung-Box test suggest that the autocorrelations of residual values act as white noise. Regarding monthly occurrences in general and by gender, the SARIMA models (2,0,0) (2,0,0), (0,1,1) (0,1,1) and (0,1,1) (2, 0, 0) were the ones that mostly adjusted to the data respectively. The model SARIMA has proven to be an adequate tool for predicting and analyzing the trends in VL incidence in Maranhão. The time variation determination and its prediction are decisive in providing guidance in health measure intervention.

Resumo A leishmaniose visceral (LV) é uma doença de natureza infecciosa, predominante em países de zonas tropicais. A predição de ocorrência de doenças infecciosas através da modelagem epidemiológica tem se revelado uma importante ferramenta no entendimento de sua dinâmica de ocorrência. O objetivo deste estudo foi desenvolver um modelo de previsão da incidência da LV no Maranhão usando o modelo de Média Móvel Integrada Autocorrelacionada Sazonal (SARIMA). Foram coletados os dados mensais de casos de LV através do Sistema de Informação de Agravos de Notificação (SINAN) correspondentes ao período de 2001 a 2018. O método de Box-Jenkins foi aplicado para ajustar um modelo de predição SARIMA para incidência geral e por sexo (masculino e feminino) de LV para o período de janeiro de 2019 a dezembro de 2023. Durante o período de 216 meses dessa série temporal, foram registrados 10.431 casos de LV no Maranhão, com uma média de 579 casos por ano. Em relação à faixa etária, houve maior registro no público pediátrico (0 a 14 anos). Houve predominância do sexo masculino, com 6437 casos (61,71%). Os valores do teste de Box-Pierce para incidência geral, sexo masculino e feminino reforçados pelos resultados do teste Ljung-Box sugerem que as autocorrelações de resíduos apresentam um comportamento de ruído branco. Para incidência mensal geral e por sexo masculino e feminino, os modelos SARIMA (2,0,0) (2,0,0), (0,1,1) (0,1,1) e (0,1,1) (2, 0, 0) foram os que mais se ajustaram aos dados, respectivamente. O modelo SARIMA se mostrou uma ferramenta adequada de previsão e análise da tendência de incidência da LV no Maranhão. A determinação da variação temporal e sua predição são determinantes no norteamento de medidas de intervenção em saúde.

Herein, a modified indirect method was established for the determination of 3-monochloropropane-1,2-diol esters (3-MCPDEs) and glycidyl esters (GEs), employing magnetic solid phase extraction by boronic acid-functionalized magnetic nanoparticles to replace the traditional clean-up procedure. Compared with routine methods, it has been proved to be more sensitive with limits of detection in the range of 0.02-1.5 µg/kg and less susceptible to contamination of phenylboronic acid derivatives and fatty acid methyl esters. The proposed method was applied to analyze 42 samples covering the entire infant formula (IF) production chain. Results revealed that homogenization process contributed 79-91 % of the total growth of the contaminants due to the vegetable oil addition, while the following evaporation and spray-drying processes contributed 9-21 % of the total growth owing to involved heat treatment. The GE levels in final IF products exceeded the maximum level set by EU regulation 2020/1322, indicating quality safety concerns in the production chain.

BACKGROUND: The management of congenital nephrotic syndrome of the Finnish type (CNF) is challenging. It is difficult to withdraw intravenous albumin infusions, resulting in long-term hospitalization. In addition, fatal hypotension after bilateral nephrectomy has been reported. In our center, we have performed unilateral nephrectomy during early infancy. METHODS: Infants diagnosed with CNF between 2011 and 2020 in our institution were enrolled. We examined the clinical course before and after unilateral nephrectomy and evaluated the effectiveness of this strategy. RESULTS: Seven patients (all showing NPHS1 mutations) were enrolled. All required daily intravenous albumin infusion via central venous catheter (CVC). Unilateral nephrectomy was performed at a median of 76 days of age (59-208 days). Surgical complications did not occur in any of patients. The mean albumin dose was decreased after unilateral nephrectomy (2.0 vs 0.4 g/kg/day; p = 0.02). Intravenous albumin infusion could be withdrawn at a median of 17 days, the CVC removed at a median of 21 days, and they discharged at a median of 82 days after unilateral nephrectomy. Although bacterial infections were noted seven times before unilateral nephrectomy, only one episode occurred after surgery. Four patients initiated peritoneal dialysis at two to three years of age and all of them underwent kidney transplantation thereafter. CONCLUSIONS: Unilateral nephrectomy during early infancy may be an effective treatment allowing for withdrawal from albumin infusion, prevention of complications, withdrawal from CVCs and shortening hospital stay for patients with CNF.

BACKGROUND: It is quite difficult to distinguish retractile testis from gliding testis, which requires different treatment planning in the clinic setting. We evaluated practice patterns of urologists in Korea regarding the diagnosis and management of retractile and gliding testes. METHODS: We mailed or e-mailed self-completion questionnaires consisting of 20 items to 106 urologists practicing in Korean hospitals concerning the diagnosis and treatment of cryptorchidism. We collected and analyzed the responses statistically. RESULTS: Responses were received from 62 urologists. The response rate was 58.5%. Thirty-seven urologists (59.7%) actually felt they had difficulty in distinguishing retractile testis from gliding testis in the clinic setting. This rate was higher for non-pediatric urologists (78.1%) than for pediatric urologists (40.0%) (P = 0.006). In cases of infant retractile testis, only five urologists (8.1%) said that they would perform orchiopexy immediately, with 54 (87.1%) urologists saying they would do follow-up. In cases of preschool-age children with retractile testis, 17 urologists (27.4%) said that they would perform orchiopexy immediately with 41 (66.1%) urologists saying they would do follow-up. In cases of infant gliding testis, 37 urologists (59.7%) said that they would perform orchiopexy immediately with 24 (38.7%) urologists saying they would do a follow-up. CONCLUSION: More than half (59.7%) of Korean urologists revealed it challenging to distinguish retractile testis and gliding testis in the clinical setting. The more it was difficult to diagnose retractile testis with certainty, the more frequent surgical correction was chosen for treatment. Therefore, it is essential to prevent unnecessary surgical treatment by establishing a practical guideline.

PURPOSE: Maternal schizophrenia is linked to complications in offspring near the time of birth. Whether there is also a higher future risk of the child having a complex chronic condition (CCC) - a pediatric condition affecting any bodily system expected to last at least 12 months that is severe enough to require specialty care and/or a period of hospitalization - is not known. METHODS: In this population-based health administrative data cohort study (Ontario, Canada, 1995-2018), the risk for CCC was compared in 5066 children of women with schizophrenia (the exposed) vs. 2,939,320 unexposed children. Adjusted hazard ratios (aHR) were generated for occurrence of any CCC, by CCC category, and stratified by child sex, and child prematurity. RESULTS: CCC was more frequent in the exposed (7.7 per 1000 person-years [268 children]) than unexposed (4.2 per 100 person-years [124,452 children]) - an aHR of 1.25 (95% CI 1.10-1.41). aHRs were notably higher in 5 of 9 CCC categories: neuromuscular (1.73, 1.28-2.33), cardiovascular (1.94, 1.64-2.29), respiratory (1.83, 1.32-2.54), hematology/immunodeficiency (2.24, 1.24-4.05) and other congenital or genetic defect (1.59, 1.16-2.17). The aHR for CCC was more pronounced among boys (1.32, 1.13-1.55) than girls (1.16, 0.96-1.40), and of similar magnitude in term (1.22, 1.05-1.42) and preterm infants (1.18, 0.95-1.46). CONCLUSIONS: The risk for a CCC appears to be higher in children born to women with schizophrenia. This finding introduces opportunities for targeted preconception counselling, optimization of maternal risk factors, and intervention to support a vulnerable parent population who will experience unique challenges caring for a child with CCCs.

OBJECTIVES: This study aimed to determine the prevalence rate of gynecomastia, determine mean glandular breast tissue sizes, and evaluate whether there is any difference in the prevalence rate of gynecomastia according to age using three different reference values of glandular breast tissue size (≥5, ≥10, ≥20 mm) in the pediatric age group. METHODS: Glandular breast tissue sizes were measured retrospectively from thoracic computed tomography (CT) images taken for other reasons in 961 boys aged 1-18 years. RESULTS: When each breast was evaluated separately (1,922 breasts), gynecomastia was observed in 1,001 (52.1%), 719 (37.4%), and 216 (11.2%) breasts with ≥5, ≥10, and ≥20 mm considered as reference values, respectively. A significant difference was found in terms of gynecomastia (p<0.001) and mean glandular breast tissue size (p<0.001) with respect to age. CONCLUSIONS: New studies are currently needed to determine the glandular breast tissue size and the prevalence rate of gynecomastia in boys, and thoracic CT images can be used for this purpose.

Resistance to thyroid hormone syndrome (RTHS) is defined as increased thyroxine and triiodothyronine associated with normal or increased thyrotropin. This is usually due to a pathogenic variant of the gene coding for thyroid hormone receptor B (THRB). THRB is a rare genetic disorder characterized by an altered response of target tissue to the thyroid hormone action. Retrospective cross-sectional observational study with diagnosis of RTHS evaluated in secondary and tertiary hospitals for 6 years, from 2014 to 2020, in order to describe variables including age, sex, anthropometric data, clinical and biochemical characteristics of patients, who were divided according to age, in a pediatric group from 0 to 14 years (index cases), and an adult group composed of adult relatives of index cases. A molecular analysis of the THRB gene was performed. The total retrospective cohort included 7 pediatric patients and 15 adults. We found 22 cases with a clear male predominance (14/22). Mean age is 24.8 years old (22 days-70 years). Patients were referred because of symptoms 18.2% (4/22), analysis results 22.7% (5/22), or familial study 59.1% (13/22). About 31.8% (7/22) cases show goiter, 31.8% (7/22) sympathetic symptoms and 13.6% (3/22) abnormalities in behavior. In most cases, 77.3%, (17/22) show familial background of thyroid abnormalities. It is important to remark that 18.2% (4/22) relatives received previous incorrect treatments such as thyroidectomy, because of wrong diagnosis. In conclusion, a better understanding of RTHS, its prompt molecular diagnosis and genetic counseling, could avoid unnecessary tests and inappropriate treatments.

BACKGROUND: Outcomes for infants who survive mild-moderate hypoxic ischemic encephalopathy (HIE) into adolescence is relatively uncharted. AIMS: We examined neuropsychological and behavioral outcomes in adolescents with mild and moderate HIE, using both parent and self - informants, and including healthy peers and nearest age siblings as controls. PARTICIPANTS: 23 adolescents with a history of mild-moderate HIE (M age = 14.45 years, SD = 1.03; 14 boys and 9 girls) were recruited from an original cohort of 53. A group of their nearest - age siblings (n = 13), and healthy peers (n = 14) were recruited as controls. OUTCOME MEASURES: A number of neuropsychological sub-tests, taken from the WISC-V.UK, Children's Memory Scale, NEPSY, WIAT-III.UK, Rey Complex Figure Copy Test and British Picture Vocabulary Scale were administered. Behavioral adjustment was assessed using the Strengths and Difficulties Questionnaire and the competence subscales of the Child Behavior Checklist. RESULTS: No differences in neuropsychological and behavioral outcomes were observed between mild and moderate HIE cohorts. Together they had significantly lower scores on tests of attention/executive functioning, verbal reasoning and sensory-motor ability compared to healthy peers, with moderate to large effect sizes. Remedial provision at school was greater in the HIE group. Parents reported elevated levels of peer problems in the HIE group compared to both siblings and healthy peers. Reduced competencies were also observed. CONCLUSIONS: We found evidence that both mild and moderate survivors of HIE experience neuropsychological, school and peer relationship problems in adolescence.

En marzo de 2020 se confirma el primer caso de enfermedad por coronavirus en Uruguay, recomendándose un confinamiento social. La atención sanitaria se redujo a servicios de urgencia y emergencia (SE). Objetivo: analizar las características de las consultas pediátricas en los SE del subsector público y privado en Uruguay, durante los primeros 4 meses de la pandemia por SARS-CoV-2. Metodología: estudio descriptivo, retrospectivo, multicéntrico. Resultados: participaron 23 SE de todas las regiones del país. Período 1 prepandemia: 14/03/19-29.07.19, período 2: 14/03/20-29/07/20 Consultas: período 1 n=121.116, período 2 n=33.099 (desciende 73%). Hospitalizaciones desde el SE: período 1 n= .6649 (tasa 5,5%). Período 2: n=2.948 (tasa 9,5%). Diagnósticos período 1: infección respiratoria aguda (IRA) alta 39.892 (33%), IRA baja 86.56 (7%), trauma menor 8.651 (7%), gastroenteritis 8.044 (6,6%), crisis asmática/CBO 7.974 (6,5%), lesiones 4.389 (3,6%), dolor abdominal 3.528 (3%), problemas de salud mental 859 (0,7%), convulsiones 758 (0,7%), patología social 678 (0,5%). Diagnósticos 2020: IRA alta 5.168 (16%), trauma menor 2.759 (8%), lesiones 2.652 (8%), dolor abdominal 1.494 (4,5%), gastroenteritis 1.296 (4%), asma/CBO 1.095 (3,3%), IRA baja 700 (2,1%), patología social 522 (1,6%), problemas de salud mental 471 (1,4%), convulsiones 408 (1,2%). Conclusiones: en los primeros meses de la pandemia hubo una reducción sostenida y significativo de consultas pediátricas en los SE. No hubo aumento en frecuencia absoluta de ninguno de los diagnósticos. Se registró un descenso histórico de las IRA bajas y las hospitalizaciones por esta causa en todo el país. Mantener una vigilancia de las consultas en los SE permitiría identificar e intervenir oportunamente si se produjeran cambios o situaciones de riesgo hasta el momento no detectadas.

In March 2020 the first case of coronavirus disease was confirmed in Uruguay, and lockdown was recommended. Health care services were reduced to Urgency and Emergency Services (ES). Objectives: to analyze the epidemiological characteristics of pediatric visits to the ES of the public and private subsector in Uruguay, during the first 4 months of the SARS-CoV-2 pandemic. Methods: descriptive, retrospective. Results: 23 institutions participated. 2 periods were considered: 1) pre-pandemic, 03/14/19 to 07/29/19, 2) 03/14/20 to 07/29/20. Visits: period 1: n=121,116 (< 15 years), period 2: n=33.099 (73% decrease). Hospital admissions: period 1: n=6,649 (rate 5.5). Period 2: n=2.948 (rate 9,5). Diagnoses period 1: High acute respiratory infection 39,892 (33%), low acute respiratory infection 8,656 (7%), minor trauma 8,651 (7%), gastroenteritis 8,044 (6,6%), asthmatic crisis/CBO 7.974 (6,5%), injuries 4,389 (3,6%), abdominal pain (3,528) 3%, mental health problems 859 (0.7%), seizures 758 (0.7%), social pathology 678 (0.5% ). 2020 diagnoses: high acute respiratory infection 5.168 (16%), minor trauma 2,759 (8%), injuries 2,652 (8%), abdominal pain 1,494 (4.5%), gastroenteritis 1,296 (4%), asthma/CBO 1,095 (3,3%), low acute respiratory infection 700 (2,1%), social pathology 522 (1,6%), mental health problems 471 (1,4%), seizures 408 (1,2%). Conclusions: in the first months of the pandemic there was a sustained and significant reduction in pediatric consultations in ES. There was no increase in absolute frequency of any of the diagnoses. There was a historical decrease in low respiratory infections and hospitalizations due to this cause in the whole country. Maintaining a surveillance of the visits in the ES would enable practitioners to identify and take action in case of changes or previously undetected risk situations.

La malformación congénita de la vía aérea pulmonar (MVAP), antes llamada malformación adenomatoidea quística pulmonar, es una rara anormalidad del desarrollo de las vías respiratorias terminales. Las lesiones son de distribución y tamaños variables, usualmente unilaterales. El diagnóstico puede realizarse desde el período prenatal mediante ecografía gestacional, encontrándose, en ocasiones, graves repercusiones fetales. En los recién nacidos la enfermedad puede manifestarse con dificultad respiratoria aguda. En niños y adultos puede diagnosticarse ante infecciones pulmonares recurrentes u otras complicaciones. En pacientes sintomáticos está indicado el tratamiento quirúrgico para prevenir infecciones y la transformación neoplásica; sin embargo, sigue siendo controversial el tratamiento profiláctico frente al tratamiento expectante en pacientes asintomáticos. Se presenta el caso clínico de una lactante de 2 meses, que en el curso de una bronquiolitis se realizó una radiografía de tórax que evidenció una imagen radiolúcida del lóbulo medio. La tomografía computada visualizó gran imagen quística en pulmón derecho, que podría corresponder a una MVAP. Se decidió tratamiento quirúrgico coordinado. Se realizó una segmentectomía, confirmándose con anatomía patológica una MVAP tipo IV. Evolucionó favorablemente.

Congenital pulmonary airway malformation (CPAM), formerly called pulmonary cystic adenomatoid malformation, is a rare developmental abnormality of the terminal airways. Lesions are of variable size and distribution, usually unilateral. The diagnosis can be made from the prenatal period by means of gestational ultrasound, occasionally causing serious fetal repercussions. In newborns, the disease may manifest itself through acute respiratory distress. In children and adults it can be diagnosed through recurrent lung infections or other complications. In symptomatic patients, surgical treatment is indicated to prevent infections and neoplastic transformation. However, prophylactic versus expectant management in asymptomatic patients remains controversial. We present the clinical case of a 2-month-old infant who, during the course of bronchiolitis underwent a chest X-ray that revealed a radiolucent image of the middle lobe. The computed tomography scan showed a large cystic image in the right lung, which could be linked to an CPAM. The surgical treatment was carried out and the segmentectomy confirmed a pathological type IV CPAM. The patient evolved favorably.

Aim: To verify the validity of maternal reports on the number of deciduous teeth erupted in their children. Methods: This cross-sectional study was performed with children enrolled in a Birth Cohort at the age of 12 months in the first stage and 24 months in the second stage. At both stages, children were clinically examined, and mothers reported the number of teeth of their children. Comparison between groups was performed using the Mann-Whitney non-paired Wilcoxon test. Level of agreement between two methods were estimated by the Observed Agreement, Weighted Kappa and Intraclass Correlation coefficients. Results: A total of 125 children were examined in the first stage, with mean number of reported teeth of 6.2. In the second stage, 149 children were examined, with mean number of reported teeth of 15.9. High level of agreement, kappa values and intraclass correlation coefficients were observed for both arches in both periods (p<0.001). Conclusions: Maternal report on the number of teeth erupted in children was reliable and valid. Thus, it seems to be a useful instrument for collecting data in population-based epidemiological studies targeting young children

Objective: Prenatal phthalate exposure has been associated with placental inflammatory factors and infant allergic rhinitis (AR). However, the results are inconclusive. We designed a population-based cohort study to examine the effects of placental inflammatory biomarkers on the sex-dependent associations between maternal phthalate exposure and infant AR. Methods: A total of 2,348 pregnant women from Ma'anshan, Anhui Province, China, who were screened before antenatal visits and met the inclusion criteria, were included in the present study. We assessed AR in their offspring aged 36 months with a questionnaire. Quantitative PCR was performed to measure placental inflammatory factor mRNAs. The independent samples t-test and multivariable logistic regression were used to determine the associations between infant AR and maternal phthalates. Results: Childhood AR may be related to education and family monthly income ( P = 0.01). The phthalate metabolites, mono (2-ethylhexyl) phthalate (MEHP), mono (2-ethyl-5-hydroxyl) phthalate (MEHHP), in pregnant women were associated with a significantly increased risk for infant AR in males [ P < 0.05; odds ratio ( OR): 1.285; 95% confidence interval ( CI): 1.037-1.591, and OR: 1.232, 95% CI: 1.008-1.507, respectively], but not females. Additionally, irritably-increased expression levels of HO-1 and IL-4 were associated with AR in male infants ( OR: 1.175; 95% CI: 1.038-1.329 and OR: 1.181; 95% CI: 1.056-1.322, respectively). The association between maternal urinary MEHHP and placental HO-1 was marginally significant according to mediation analysis. Conclusion: The associations of maternal MEHHP and MEOHP levels with fetal AR in males were significant. Placental HO-1 was a fractional mediator in the associations between MEHHP and AR. Thus, the placenta should be further investigated as a potential mediator of maternal exposure-induced disease risk in children.

OBJECTIVE: To identify developmental symptoms reported at firsts doctor visits by parents of children later diagnosed with Autism Spectrum Disorder (ASD). DESIGN: Cohort study. SETTING: The study was conducted in the Department of Psychiatry Research of "Prof. Dr. Alexandru Obregia" Clinical Psychiatry Hospital from Bucharest between September 2019 and May 2021. PATIENTS: 105 cases: 82 boys and 23 girls, 100 children with autism, and 5 patients with Asperger's syndrome. INTERVENTION: ASD was diagnosed according to the DSM-5 criteria, ADOS-1 (Autism Diagnostic Observation Schedule, 1st Edition) and/or ADI-R (Autism Diagnostic Interview-Revised) tests scores; features reported by the parents for which they presented to the doctor for a diagnosis were taken into consideration. MAIN OUTCOME MEASURES: The age at first presentation to the doctor; the most common early signs reported by the parents of children with ASD. RESULTS: The age at first presentation to the doctor in our group was between 9 months and 14 years. The most common early signs reported by parents were: delayed language development, deficits in understanding verbal instructions/indications, and hyperactivity and aggressivity. In the case of patients with Asperger's syndrome, the reported features were hyperactivity and aggressivity, learning difficulties, and social interaction problems. Regression and delay in language development occurred more often in boys than in girls. CONCLUSIONS: Parents, as well as family doctors or paediatricians, should pay great attention to the children's behaviour, alongside their cognitive and language development. Early detection is essential for early intervention and our results can be used to develop training programs for parents and paediatricians for early recognition of ASD.

The objective was to know the behavior of fractures in Mexican children and adolescents. According to our study, fractures in Mexican male children and adolescents seem to be decreasing; however, we still need more national studies to know the possible causes of these fractures. PURPOSE: To describe the trends of fractures in Mexican children and adolescents across a 12-year period (2007 to 2019), and to analyze if these trends have changed over time between sexes and age groups. METHODS: We identified all fracture cases registered in children and adolescents (0 to 19 years) at the emergency rooms and surgical departments of the Mexican Institute of Social Security between January 2007 and December 2019. We used ICD-10 to classify the fractures. The population was divided into two age groups: children (0 to 9 years) and adolescents (10 to 19 years). Additional information regarding sex and age was gathered up as well. We calculated annual incidence; incidence rates are presented per 10,000 population at risk. Changes in fracture trends were calculated using the average annual percentage change (AAPC). RESULTS: Over 12 years, 1,400,443 fractures were registered. The most frequent site of fracture was forearm in 37.1% followed by shoulder (18.1%). The overall rates of fractures have remained similar over 12 years (86.5, IQR 81.0-94.2); however, a significant decrease in fractures was observed the last 3 years (2017-2019). According to the AAPC, only in men, in both age groups, a significant decrease in fractures was observed. CONCLUSION: This is the first study in Mexico to follow the behavior of fractures in the pediatric population over 12 years. Fractures seem to be decreasing in children and adolescents. An epidemiological follow-up of childhood fractures is necessary to understand the causes of fractures to generate better prevention and treatment strategies.

Importance: Language development builds on speech perception, with early disruptions increasing the risk for later language difficulties. Although a major postpartum depressive episode is associated with language development, this association has not been investigated among infants of mothers experiencing a depressed mood at subclinical levels after birth, even though such a mood is frequently present in the first weeks after birth. Understanding whether subclinical depressed maternal mood after birth is associated with early language development is important given opportunities of coping strategies for subclinical depressed mood. Objective: To examine whether depressed maternal mood at subclinical levels 2 months after birth is associated with infant speech perception trajectories from ages 2 to 6.5 months. Design, Setting, and Participants: In this longitudinal cohort study conducted between January 1, 2018, and October 31, 2019, 46 healthy, monolingual German mother-infant dyads were tested. The sample was recruited from the infants database of the Max Planck Institute for Human Cognitive and Brain Sciences. Initial statistical analysis was performed between January 1 and March 31, 2021; the moderation analysis (results reported herein) was conducted between July 1 and July 31, 2022. Exposures: Mothers reported postpartum mood via the German version of the Edinburgh Postnatal Depression Scale (higher scores indicated higher levels of depressed mood, with a cutoff of 13 points indicating a high probability of clinical depression) when their infants were 2 months old. Main Outcomes and Measures: Electrophysiological correlates of infant speech perception (mismatch response to speech stimuli) were tested when the infants were aged 2 months (initial assessment) and 6.5 months (follow-up). Results: A total of 46 mothers (mean [SD] age, 32.1 [3.8] years) and their 2-month-old children (mean [SD] age, 9.6 [1.2] weeks; 23 girls and 23 boys) participated at the initial assessment, and 36 mothers (mean [SD] age, 32.2 [4.1] years) and their then 6.5-month-old children (mean [SD] age, 28.4 [1.5 weeks; 18 girls and 18 boys) participated at follow-up. Moderation analyses revealed that more depressed maternal subclinical postpartum mood (mean [SD] Edinburgh Postnatal Depression Scale score, 4.8 [3.6]) was associated with weaker longitudinal changes of infants' electrophysiological brain responses to syllable pitch speech information from ages 2 to 6.5 months (coefficient: 0.68; 95% CI, 0.03-1.33; P = .04). Conclusions and Relevance: The results of this cohort study suggest that infant speech perception trajectories are correlated with subclinical depressed mood in postpartum mothers. This finding lays the groundwork for future research on early support for caregivers experiencing depressed mood to have a positive association with children's language development.

OBJECTIVE: to describe and compare the frequency of neurobehavioral signs in preterm infants in traditional and humanized body weight check. METHODS: a quantitative, quasi-experimental, cross-over study, carried out in a Neonatal Unit at a university hospital with a sample of 30 preterm newborns, randomly assigned and allocated in control group (traditional) and intervention group (humanized), with collection of general data, vital signs before and after procedures and footage. RESULTS: there was a higher frequency of approach signs in humanized weight check compared to traditional check. Moreover, withdrawal signs were more frequent in traditional weight check compared to humanized check. CONCLUSION: in this regard, humanized body weight check provided greater benefits to preterm infants, making it necessary to foster discussions about humanization of care, so that this practice can be performed routinely in health units.
