Is it safe to use ovarian follicular fluid from cows seropositive for brucellosis in the production of in vitro embryos?

Animal reproduction biotechniques are important tools for the technological advancement of livestock, as they allow the selection of the reproductive potential of superior quality females and males; however, infectious diseases that have a predilection for the reproductive system can be a hindrance for the use of these technologies. Therefore, the present study aimed to detect Brucella spp. in the ovarian follicular fluid of brucellosis-positive bovine cows. A total of 47 bovine ovarian follicular fluid aspirates from cows, positive in tests for brucellosis and from Brucella-positive herd, were submitted to PCR. The primers used in the PCR were specific to the genus Brucella (bcsp31 gene). All 47 bovine aspirates were negative for Brucella spp. 0.00% (95% CI: 0.00-4.00%). Our results demonstrated that Brucella spp. was absent in the ovarian follicular fluid from seropositive cows, which indicates that Brucella spp.-infected cows could be used for reproductive biotechnologies carried out with follicular aspirates. Future studies are needed to more precisely evaluate the feasibility and safety of using these oocytes from brucellosis-seropositive cows to transfer embryos to heifers/cows not infected by Brucella, aiming to produce calves free of the infection.

Biomechanical properties of the capsule and extracellular matrix play a major role during the Wolffian/epididymal duct development.

BACKGROUND: The epididymis is important for sperm maturation and without its proper development, male infertility will result. Biomechanical properties of tissues/organs play key roles during their morphogenesis, including the Wolffian duct. It is hypothesized that structural/bulk stiffness of the capsule and mesenchyme/extracellular matrix that surround the duct is a major biomechanical property that regulates Wolffian duct morphogenesis. These data will provide key information as to the mechanisms that regulate the development of this important organ. OBJECTIVES: To measure the structural/bulk stiffness in Pascals (force/area) of the capsule and the capsule and mesenchyme together that surrounds the Wolffian duct during the development. To examine the relative membrane tension of mesenchymal cells during the Wolffian duct development. Since Ptk7 was previously shown to regulate ECM integrity and Wolffian duct elongation and coiling, the hypothesis that Ptk7 regulates structural/bulk stiffness and mesenchymal cell membrane tension was tested. MATERIALS AND METHODS: Atomic force microscopy and a microsquisher compression apparatus were used to measure the structural stiffness. Biomechanical properties within the membranes of cells within the capsule and mesenchyme were examined using a membrane-tension fluorescent probe. RESULTS AND DISCUSSION: The structural stiffness (Pascals) of the capsule and underlying mesenchyme was relatively constant during development, with a significant increase in the capsule at the later stages. However, this increase may reflect the ECM and associated mesenchyme being close to the capsule because the coiling of the duct pushed or compressed them into that space. Keeping the capsule and mesenchyme/ECM at constant stiffness would ensure that the duct will continue to coil under similar biomechanical forces throughout the development. Cells within the capsule and mesenchyme at different Wolffian duct regions during the development had varying degrees of membrane lipid tension. It is hypothesized that the dynamic changes ensure the duct is kept at a constant stiffness regardless of any external forces. Loss of Ptk7 resulted in an increase in stiffness at E18.5, which was presumable due to the loss of integrity of the ECM within the mesenchyme. CONCLUSION: Biomechanical properties of the capsule and the mesenchyme/extracellular matrix that surround the Wolffian duct play an important role toward Wolffian duct morphogenesis, thereby allowing for the proper development of the epididymis and subsequent male fertility.

Can Diet Alter the Intestinal Barrier Permeability in Healthy People? A Systematic Review.

Dietary factors can modify the function of the intestinal barrier, causing permeability changes. This systematic review analyzed evidence on the link between diet or dietary interventions and changes in intestinal barrier permeability (IBP) in healthy individuals. A systematic search for primary studies was conducted using the virtual databases EMBASE, PubMed, Web of Science, CINAHL, and Scopus. This review adhered to PRISMA 2020 guidelines, assessing the methodological quality using the Newcastle-Ottawa scale for observational studies and ROB 2.0 for randomized clinical trials. Out of 3725 studies recovered, 12 were eligible for review. Chicory inulin and probiotics reduced IBP in adults with a moderate GRADE level of evidence. The opposite result was obtained with fructose, which increased IBP in adults, with a very low GRADE level of evidence. Only intervention studies with different dietary components were found, and few studies evaluated the effect of specific diets on the IBP. Thus, there was no strong evidence that diet or dietary interventions increase or decrease IBP in healthy individuals. Studies on this topic are necessary, with a low risk of bias and good quality of evidence generated, as there is still little knowledge on healthy populations.

Psychometric Validation of a Hearing Screening Questionnaire for Preschoolers Based on Language Development Evaluation by Caregivers.

INTRODUCTION: This study aimed to validate three age-adjusted versions of a Hearing Screening Questionnaire for Preschoolers, in Brazilian Portuguese, based on parents' perception of their children's hearing and oral language. METHODS: Psychometric validation was conducted on three questionnaires, each comprising nine items with yes/no responses. Three items focused on hearing screening at birth, and six assessed hearing and oral language. The study included 152 parents and their children, who attended daycare centers in Belo Horizonte, Brazil. The children were categorized into three age bands: 12-18 months, 19-35 months, and 36-48 months. Audiological assessments, including tympanometry, transient-evoked otoacoustic emissions (TEOAE), and pure-tone audiometry (when applicable), were performed on the children. In case of abnormal findings in the previous exams, auditory brainstem response (ABR) testing was conducted. Descriptive data, false alarm, and false-negative analyses were carried out. RESULTS: Considering any type of hearing loss, whether unilateral or bilateral, the questionnaires showed a false-negative rate of 41.17% (7/17 children). However, when considering only bilateral hearing loss, the questionnaire showed a false alarm rate of 31.69% (45/142) and a false-negative rate of 30.0% (3/10). When focusing exclusively on sensorineural hearing loss, the questionnaire identified two children (1.31%), with a false-negative rate of 0% but a false-positive rate of 33.33%. CONCLUSION: Language-development-oriented questionnaires allowed quick screening of potential hearing loss in preschoolers. This study found a robust hit rate with these questionnaires. Their validation signifies a promising and cost-effective tool for conducting hearing screenings in preschool children, especially in nations lacking a comprehensive school screening policy. The validated questionnaire affords an easy-to-apply, low-cost, and effective instrument for preschool hearing screening.

Clinical-epidemiological profile of the canine population in a shelter, Minas Gerais, Brazil, 2019-2020.

The aim of this study was to analyze the demographic, clinical, and hematological aspects of the population in a dog shelter located in the municipality of Lavras, Brazil. All animals were microchipped and evaluated by veterinarians. Whole blood samples were obtained from 329 dogs in the months of July-August 2019 and from 310 dogs in the months of January-February 2020. Most of the dogs were of mixed breed, received anti-rabies and polyvalent vaccines (100%), were dewormed (100%), and were spayed/neutered (98.59%), with a predominance of adult (86.51%), short-hair (67.51%), normal body condition (65.57%), medium-size (62.57%), and female (62.36%). The main clinical alterations detected were enlarged lymph nodes (38.69%), skin lesions (31.50%), overweight (23.32%), obesity (6.07%), elevated temperature (17.05%), and ear secretion (15.72%). Regarding hematological alterations, thrombocytopenia (36.31%), leukopenia (15.92%), anemia with decreased hemoglobin values (10.60%), hematocrit (9.70%), and red blood cells (5.14%) were observed. Most of the shelter dogs were apparently healthy, but specific measures for nutritional, dermatological, otological and disease management should be implemented once the health changes are verified, as they impact the general state of the population and adoptions.

Analysis of specific risk factors of neurodevelopmental disorder in hearing-impaired infants under ten months of age: "EnTNDre" an opening research stemming from a transdisciplinary partnership.

INTRODUCTION: Approximately 20% of children born with severe to profound hearing loss (HL) have an associated disorder that poses a neurodevelopmental risk [1]. The objective of this study is to identify the criteria and profiles of deaf infants at risk of neurodevelopmental disorders (NDD) to provide early intervention. METHODS: Twenty-two infants aged three to ten months with bilateral congenital deafness were included. Each child attended a consultation with a psychiatrist specializing in the development of hearing-impaired infants as part of their ENT follow-up. The quality of their early development was analyzed using the Olliac grid and well-known postural and sensorimotor criteria. The children were then classified into three groups: normal examination (Group 1), evident NDD (Group 2), and intermediate examination (Group 3). Early medical history, the etiology of deafness, cerebral imaging, and vestibular test results were collected and compared in the different groups. RESULTS: The average age of the children at the time of observation was seven months (3-10 months). All had sensorineural HL, with identified causes in 13 out of 22 cases: five cases of connexin 26 gene mutation, three cases of CHARGE syndrome, two CMV infections, one Usher syndrome, one GATA3 mutation, and one LHPL5 mutation. The average score on the Olliac grid was nine (0-15), and abnormal postural and sensorimotor behaviors were found in 15 cases out of 22 (68%). 27% of the children were classified in Group 1, 45% in Group 2, and 27% in Group 3. Children with non-isolated HL, abnormal brain MRI (8/22), malformations outside the auditory system (10/22), vestibular impairments (9/22), and/or CMV infections (2/22) were distributed as follows: 2/6 in Group 1, 9/10 in Group 2, and 3/6 in Group 3. 8/22 children had suffered perinatal complications (0/6 in Group 1, 6/10 in Group 2, and 2/5 in Group 3). Only one child had a first-degree relative with NDD. He belonged to Group 2. DISCUSSION: To our knowledge, this paper is the first to describe the development of infants with congenital deafness. It is based on an observation time that had been included in the procedure of multidisciplinary evaluations prior to cochlear implantation (CI), thanks to the partnership between a psychiatric center for deaf children and an ENT-pediatric implantology service. This consultation was aimed at assessing the quality of neurodevelopment and identifying NDD without a specific referral, with good acceptability for families. Using the Olliac grid and postural and sensorimotor criteria developed to be assessed in the routine care consultation, we identified evident early signs of NDD in 45% of infants. This group (Group 2) requires early, targeted, developmental support. Some children in an intermediate zone (Group 3) require further observation and support. CONCLUSION: The very early identification of NDD seems to be relevant in the care of hearing-impaired infants. The use of the Olliac grid and developmental scales seems relevant to identifying infants at risk for NDD.

Child malnutrition in Brazil: Public health issue that needs awareness.

In developing countries, child malnutrition is a serious public health problem. Brazil is a country that has several projects to combat hunger and malnutrition in early childhood, but 2021 was a year with the highest number of hospitalizations of children up to 60 months of life in the last 13 years. Factors such as social disparities and the Covid-19 pandemic contributed to this scenario.

Comparative toxicological evaluation of carvacrol, acetylcarvacrol anda fipronil-based pesticide in human blood cells.

Plant-derived chemicals are promising substances to control arthropod pests, although synthetic ones are still the most frequently used. Thus, comparative toxicological studies are needed to determine if natural substances are safe alternatives to replace the use of synthetic chemicals. This study aimed to compare the toxicity of carvacrol (natural origin), acetylcarvacrol (semi-synthetic) and a fipronil-based pesticide (synthetic). We assessed the effects of these chemicals on hemolytic activity, erythrocytes morphology and leucocyte viability using whole blood from human subjects. Additionally, DNA damage was evaluated through comet and DNA fragmentation assays. Fipronil and carvacrol caused hemolysis at concentrations ranging from 0.5 to 2.0%, whereas acetylcarvacrol did not cause hemolysis at 0.5 and 0.75%. Fipronil and carvacrol caused severe alterations in erythrocytes' morphology at 2%, such as ghost erythrocytes, elliptocyte-like shape and rouleau-like shape, presenting only 3.3 and 8.3% normal cells, respectively, at this concentration. However, 73.3% erythrocytes incubated with 2% acetylcarvacrol exhibited normal morphology. Fipronil considerably reduced leucocytes viability, decreasing it to 78% at 2%. Carvacrol and acetylcarvacrol showed no differences in leucocyte viability for 0.5 to 1.0%, but a decrease was observed for 2% carvacrol. The comet assay showed similar DNA damage for fipronil and carvacrol, but it was significantly lower for 1 and 2% acetylcarvacrol. Incubation with genomic DNA showed that only fipronil caused fragmentation of this molecule. Thus, we conclude that carvacrol and fipronil can present similar toxicity at higher concentrations. However, acetylation of carvacrol significantly reduced its toxicity to human blood cells compared with the other chemicals.

Impacts of COVID-19 on children and adolescents: A systematic review analyzing its psychiatric effects.

OBJECTIVE: To summarize the most relevant data from a systematic review on the impact of COVID-19 on children and adolescents, particularly analyzing its psychiatric effects. METHODS: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and included experimental studies (randomized-individually or pooled-and non-randomized controlled trials), observational studies with a group for internal comparison (cohort studies-prospective and retrospective-and case-control) and qualitative studies in the period from 2021 to 2022. RESULTS: The search identified 325 articles; we removed 125 duplicates. We selected 200 manuscripts, chosen by title and selected abstracts. We excluded 50 records after screening titles and abstracts, as they did not meet the inclusion criteria. We retrieved 150 records selected for a full reading. We excluded 90 text articles and we selected 25 records for the (n) final. Limitations: Due to the short period of data collection, from 2021 to 2022, there is a possibility of lack of relevant studies related to the mental health care of children and adolescents. In addition, there is the possibility of publication bias, such as only significant findings being published. CONCLUSION: The impact of COVID-19 on the mental health of children and adolescents is of great concern to child and youth psychiatry. Situations such as fear, anxiety, panic, depression, sleep and appetite disorders, as well as impairment in social interactions caused by psychic stress, are punctual markers of pain and psychic suffering, which have increasing impacts on the mental health panorama of children and adolescents globally, particularly in vulnerable and socially at-risk populations.

Autism and Down syndrome: early identification and diagnosis.

BACKGROUND: The diagnosis of autism spectrum disorder (ASD) in Down syndrome (DS) is underestimated because it is necessary to understand which aspects of the behavioral phenotype are related to DS and which are related to ASD. Objective: To conduct a systematic review of the literature on early identification and diagnosis of ASD in patients with DS. Data source: The VHL, MEDLINE, Cochrane, CINAHL, Scopus, Web of Science and Embase databases were searched and data were evaluated using PRISMA. Data synthesis: Out of 1,729 articles evaluated, 15 were selected. Although well studied, identification of ASD in DS can be difficult because of the need to understand which aspects of the behavioral phenotype are related to Down syndrome and which to autism. In this review, the prevalence of ASD was found to range from 12% to 41%. Early identification of autism risk in individuals with Down syndrome is still poorly studied, even though there are screening instruments for infants. Several instruments for diagnosing autism in individuals with Down syndrome were found, but a developmental approach is fundamental for making a clear diagnosis. Conclusions: Screening procedures are important for detecting early signs of autism risk in the first year of life. Careful evaluation methods are needed to establish the diagnosis, which include choosing appropriate tools for evaluation of development and cognition, and analysis of qualitative aspects of social interaction, among others. It has been indicated in the literature that early detection and timely accurate diagnosis, in association with an intervention, may benefit development, quality of life and social inclusion.

Beneficial Effects of Flaxseed and/or Mulberry Extracts Supplementation in Ovariectomized Wistar Rats.

Low endogenous estrogen action causes several injuries. Medicinal plants, such as flaxseed and mulberry, contain substances that have been shown to be effective to the organism. The aim was to verify the effects of flaxseed and/or mulberry extracts on ovariectomized Wistar rats. The animals received supplements of extracts and estrogen or saline by gavage for 60 days and were weighed weekly. Vaginal wash, blood, pituitary, uterus, liver, and kidneys were collected. Phenolic compounds and the antioxidant activity of the extracts, lipid profile, uric acid, liver enzymes, and pituitary weight were measured. Histomorphometric for uterine wall and histopathological analyses for liver and kidney were performed. Flaxseed and mulberry extracts showed great antioxidant activity and large amounts of phenolic compounds. The treatment with extracts had less weight gain, increased pituitary weight, the predominance of vaginal epithelial cells, and reduced TC, LDL-c and lipase activity, similar to estrogen animals. Estrogen or flaxseed + mulberry animals reduced VLDL-c and TAG. HDL-c, uric acid, and liver enzymes did not differ. Estrogen or extracts demonstrated trophic action on the endometrial thickness and have not shown hepatotoxicity or nephrotoxicity. We suggested the beneficial effects of flaxseed and mulberry extract as an alternative to reduce and/or prevent the negative effects caused by low estrogenic action.

The Effects of Prenatal Diagnosis on the Interaction of the Mother-Infant Dyad: A Longitudinal Study of Prenatal Care in the First Year of Life.

Introduction: Mother-child interactions during the first years of life have a significant impact on the emotional and cognitive development of the child. In this work, we study how a prenatal diagnosis of malformation may affect maternal representations and the quality of these early interactions. To this end, we conducted a longitudinal observational study of mother-child interactions from the gestational stage until the baby completed 12 months of age. Participants and Methods: We recruited 250 pregnant women from a local university hospital. Among them, 50 mother-infant dyads participated in all stages of the study. The study group consisted of 25 pregnant women with fetuses with some structural alteration and the control group consisted of 25 pregnant women with fetuses without structural anomalies. We collected obstetric and socio demographic data and pregnancy outcomes. Anxiety and depressive state data were collected using the COVI and Raskin Scales. We video-recorded the mother-infant interactions during several stages, including when the child was a newborn and when the child was 2, 4, 6, 9, and 12 months of age. The quality of the mother infant interactions were measured using the Coding Interactive Behavior (CIB). The interactive moments recorded on video was composed of three different activities, each one lasting appoximately 3 min, which included (1) Free Interaction, where the mother was instructed to interact "as usual" without any toy, (2) Toy Interaction, where the mother and baby played with a puppv, and (3) Song Interaction, where the mother and baby interacted while the mother sang the "Happy Birthday" song. Results: In the gestational phase, there was a significant difference between the groups with respect to anxiety and depression scores, which were significantly higher for the study group. In the postnatal phase, we found significant differences between the groups with respect to CIB scales after the child completed 6 months of age: the study group presented significantly higher values of Maternal Sensitivity at 6 months of age, of Baby Involvement at 9 and 12 months of age, and of Dyadic Reciprocity at 6, 9, and 12 months of age, while the control group presented significantly higher values of Withdrawal of the Baby at 6 months of age, and of Dyadic Negative States at 6 and 9 months of age. Conclusion: The support offered by the study favored the mother-infant bond and had a positive effect on the quality of interaction during the first year of life, despite the presence of prenatal diagnosis.

Vaccination for COVID-19 in children: Denialism or misinformation?

In the current pandemic scenario, vaccines for children have been scientifically approved; however, there is a challenge faced globally: parents' hesitation about vaccinating their children for COVID-19, which can hamper adherence to vaccine campaigns. This issue is due to the lack of information or access to fake news that affects the parents' power of judgment. The experience of the vaccine process with Pfizer's immunizer in several countries successfully reduced the number of hospitalized and prevented hundreds of child deaths from COVID-19. All health professionals must encourage the vaccination of children from the age of 5, sharing reliable scientific data, thus reducing the spread of fake news.

"Between the cross and the sword": Brazilian children face an influenza epidemic while still dealing with the COVID-19 pandemic.

The Influenza activity remained at inter-seasonal levels; however, influenza A(H3N2) detections continue to increase in Brazil, Chile, Paraguay, and Uruguay. Most of the activity and rising trend of A(H3N2) detections are recorded in Brazil. A bulletin issued by the Oswaldo Cruz Foundation (Fiocruz) reported significant presence of the influenza A virus, both in children and in the adult population, among cases of SARS-Cov-2.This situation is worrying, as vaccination campaigns were hampered by the COVID-19 pandemic.

High-Dose Convalescent Plasma for Treatment of Severe COVID-19.

To assess whether high-dose coronavirus disease (COVID-19) convalescent plasma (CCP) transfusion may benefit patients with severe COVID-19, we conducted a multicenter randomized trial in Brazil. Patients with severe COVID-19 who were within 10 days of initial symptom onset were eligible. Patients in the CCP group received 3 daily doses of CCP (600 mL/d) in addition to standard treatment; control patients received standard treatment only. Primary outcomes were death rates at days 30 and 60 of study randomization. Secondary outcomes were ventilator-free days and hospital-free days. We enrolled 107 patients: 36 CCP and 71 control. At day 30, death rates were 22% for CCP and 25% for the control group; at day 60, rates were 31% for CCP and 35% for control. Needs for invasive mechanical ventilation and durations of hospital stay were similar between groups. We conclude that high-dose CCP transfused within 10 days of symptom onset provided no benefit for patients with severe COVID-19.
