Influence of Monochromatic Light during Incubation on the Production and Metabolism of Low-Temperature Broiler Chicks.

The use of artificial lighting during the incubation phase is a tool that has been studied with the aim of increasing the production rates and hatchability. Using this, this study aims to investigate the effects of the luminous incidence of white and red monochromatic light on the production and metabolism of broiler chicks subjected to low temperatures. A total of 315 eggs of Ross 708 heavy breeders were used. The eggs were distributed randomly, with 35 eggs per tray, totaling 105 eggs per incubator. The treatments were the following: incubation without the use of light; the use of white monochromatic light; and the use of red monochromatic light. The lamps used were of the LED type. The samples were distributed in the factorial completely randomized experimental design with position effect on the tray. Candling, egg weighing, calculating the probability of survival and egg weight loss were performed. Temperatures were recorded using a thermographic camera. At birth, three chicks per tray were euthanized for evaluation: weight with and without yolk residue, gastrointestinal tract biometry, and blood and liver biochemistry. Analyses were performed using the R computational program. It was observed that there was a significant effect of the treatments on the levels of calcium, phosphorus, cholesterol, amylase, glucose, urea and glutamate pyruvate transaminase on the biochemical profile of the blood and on the thermographic temperatures of the eggs; the experiment was kept at low temperatures resulting in thermal stress, with an average temperature of 34.5 °C. Therefore, the use of red and white monochromatic light in the artificial incubation process for brown-colored eggs is not recommended, because in the post-hatching phase, it promoted the metabolism dysregulation on the blood biochemical profile to control the differentiation in the wavelength of traditional incubation.

Effects of athletic tape on orofacial pain and jaw movements after 24 hours of use: a randomized clinical trial. / Efeitos da bandagem elástica na dor orofacial e nos movimentos mandibulares após 24 horas de uso: ensaio clínico randomizado.

PURPOSE: To analyze the sensation of pain and the range of mandibular movements of adult individuals with temporomandibular disorder, before and after the application of the athletic tape. METHOD: This is a double-blind randomized clinical trial, in which 22 adults with temporomandibular disorder participated, randomly allocated into two groups, with group A comprising 10 women and one man (mean age 28.2±8.3 years) and group B comprising nine women and two men (mean age 26.2±3.9 years). Group A was submitted to the application of the athletic tape on the masseter with 40% stretch and the group B to the application of the athletic tape on the masseter without stretching. All participants underwent the application of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Pain threshold assessment was performed using an algometer to apply pressure to measurement points. The measurement of mandibular movements was performed using a caliper. The athletic tape was glued using the I technique, with a fixed point over the insertion and a movable point over the origin of the masseter muscle. Participants remained with the athletic tape for 24 hours and were re-evaluated. RESULTS: There was pain relief in the group A in the temporomandibular joint on the right and at the origin of the masseter on the left. The group B showed a reduction in pain in the left anterior temporal region. No differences were found in mandibular movements after intervention, as well as no difference was found in the comparison by groups. CONCLUSION: The use of the athletic tape over the masseter muscle, with stretching, for 24 hours produced relief from the sensation of pain, on the origin of the right masseter and in the right temporomandibular joint, and, without stretching, in the left anterior temporal muscle. There was no difference in the range of mandibular movements.

Chemical Composition of Extracts and Fractions from Miconia Ibaguensis (Melastomataceae) Leaves and Evaluation of Biological Activities.

The study aimed to assess the chemical composition of Miconia ibaguensis leaves extracts and fractions obtained from the ethanolic extract (EE), along with evaluating their antifungal, antibacterial, antidiabetic, and antioxidant activities. The ethyl acetate fraction (EAF) exhibited potent antifungal activity against Candida spp (1.95-3.90 µg mL-1) and potent antioxidant activity in the DPPH (1.74±0.07 µg mL-1), FRAP (654.01±42.09 µmol ETrolox/gsample), and ORAC (3698.88±37.28 µmol ETrolox/gsample) methods. The EE displayed inhibition against the α-amylase enzyme (8.42±0.05 µg mL-1). Flavonoids, hydrolysable tannins, triterpenoids, and phenolic acids, identified in the EE and fractions via (-)-HPLC-ESI-MS/MS analysis, were found to contribute to the species' biological activity potentially. These findings suggest promising avenues for further research and potential applications in pharmacology and natural products, offering new possibilities in the fight against global health issues.

Antimicrobial Use in Pig Farms in the Midwestern Region of Minas Gerais, Brazil.

The use of antimicrobials in swine production is an issue that concerns the whole world due to their impact on animal and public health. This study aimed to verify the antimicrobial use in 29 commercial full-cycle farms in the midwestern region of the state of Minas Gerais, since this region is a hub of intensive pig farming in Brazil, as well as the possible correlations between the use of antimicrobials, biosecurity, and productivity. A total of 28 different drugs used for preventive purposes were described. On average, the herds used seven drugs, exposing the piglets for 116 days and totaling 434.17 mg of antimicrobials per kilogram of pig produced. Just eight active ingredients made up 77.5% of the total number of drugs used on the studied herds. Significant differences were found between the variables, biosecurity score and number of sows, antimicrobial amount and number of drugs, number of drugs and number of sows, and between productivity and biosecurity scores. The use of antimicrobials was considered excessive in the swine farms in the state of Minas Gerais compared to what was reported in Brazil and in other countries. Educational measures and better control should be proposed to reduce the preventive use of antimicrobials.

Predicting ruminal degradability and chemical composition of corn silage using near-infrared spectroscopy and multivariate regression.

The aim of this study was to develop and validate regression models to predict the chemical composition and ruminal degradation parameters of corn silage by near-infrared spectroscopy (NIR). Ninety-four samples were used to develop and validate the models to predict corn silage composition. A subset of 23 samples was used to develop and validate models to predict ruminal degradation parameters of corn silage. Wet chemistry methods were used to determine the composition values and ruminal degradation parameters of the corn silage samples. The dried and ground samples had their NIR spectra scanned using a poliSPECNIR 900-1700 model NIR sprectrophotometer (ITPhotonics S.r.l, Breganze, IT.). The models were developed using regression by partial least squares (PLS), and the ordered predictor selection (OPS) method was used. In general, the regression models obtained to predict the corn silage composition (P>0.05), except the model for organic matter (OM), adequately estimated the studied properties. It was not possible to develop prediction models for the potentially degradable fraction in the rumen of OM and crude protein and the degradation rate of OM. The regression models that could be obtained to predict the ruminal degradation parameters showed correlation coefficient of calibration between 0.530 and 0.985. The regression models developed to predict CS composition accurately estimated the CS composition, except the model for OM. The NIR has potential to be used by nutritionists as a rapid prediction tool for ruminal degradation parameters in the field.

Early-life trauma, impulsivity and suicide attempt: a systematic review and meta-analysis.

INTRODUCTION: Suicide is a worldwide health concern and up to date there is no good predictor of it except a previous suicide attempt. Therefore, there are increasing efforts in the understanding of which factors, genetic or environmental, are associated with suicide behaviour. OBJECTIVE: To review evidence of the effect of childhood trauma and impulsivity on suicidal behavior through a systematic review and meta-analysis. METHODS: Searches were conducted on the 12th of June 2021 in the PubMed, Scopus, and Web of Science databases. Two reviewers evaluated each record for eligibility and discussed upon disagreement, when no consensus was reached, a third reviewer was involved to make a decision. RESULTS: A total of 11,530 records were identified through the searches. After duplicates were removed, 6,595 records remained to be screened. The full text was sought for 1,561 records. Our qualitative synthesis included 22 studies, from which 9 were included in the meta-analyses. We found a significant effect of sexual abuse, physical abuse, emotional abuse and physical neglect on suicide attempts in the prisoners, and Substance Use Diorder (SUD) subgroups. Moreover, there was a significant effect of Childhood Trauma Questionnaire (CTQ) total score and emotional neglect dimension for all the subgroups. CONCLUSION: The present study has provided an overview of the state-of-the-art research on childhood trauma and impulsivity and their association with suicidal behavior and quantified their effects on suicide attempts. Hopefully this evidence will be considered in future research and harnessed for clinical gain in detection and treatment of suicide behaviour.

Fluoxetine alters rat's milk properties causing impact on offspring's development.

Fluoxetine is an antidepressant used to treat several conditions including postpartum depression. This disease causes cognitive, emotional, behavioral and physical changes, negatively affecting the mother, child and family life. However, fluoxetine is excreted in breast milk, causing short and long-term effects on children who were exposed to the drug during lactation, so studies that seek to uncover the consequences of these effects are needed. Thus, the aim of this study was to evaluate the effects of fluoxetine on the nutritional characteristics of milk and on growth and neurobehavioral development of the offspring on a rat model. Lactating rats were divided into 4 groups: control group and three experimental groups, which were treated with different doses of fluoxetine (1, 10 and 20 mg/kg) during the lactation. Dams body weight and milk properties were measured, as well as offspring's growth and physical and neurobehavioral development. Results showed that the use of fluoxetine during lactation decreased dam's body weight and alters milk's properties, leading to a decrease in offspring's growth until adulthood. Therefore, the use of fluoxetine during lactation needs to be cautiously evaluated, with the benefits to the mothers and the associated risk to the offspring carefully balance.

The Impact of Long Noncoding RNAs in Tissue Regeneration and Senescence.

Overcoming senescence with tissue engineering has a promising impact on multiple diseases. Here, we provide an overview of recent studies in which cellular senescence was inhibited through the up/downregulation of specific lncRNAs. This approach prevented senescence in the bones, joints, nervous system, heart, and blood vessels, with a potential impact on regeneration and the prevention of osteoarthritis and osteoporosis, as well as neurodegenerative and cardiovascular diseases. Senescence of the skin and liver could also be prevented through the regulation of cellular levels of specific lncRNAs, resulting in the rejuvenation of cells from these organs and their potential protection from disease. From these exciting achievements, which support tissue regeneration and are not restricted to stem cells, we propose lncRNA regulation through RNA or gene therapies as a prospective preventive and therapeutic approach against aging and multiple aging-related diseases.

Infection after intramedullary nailing of femoral and tibial diaphyseal fractures.

PURPOSE: Management of fracture-related infection (FRI) after intramedullary fixation (IF) is a challenge. The aim of the present study is to describe a series of 26 patients with FRI after IF and to evaluate factors possibly related to the outcome. METHODS: Baseline variables were obtained at the time of IF: age, sex, body mass index, affected bone, open fracture, substance abuse, use of an external fixator, type of nail, reaming, soft-tissue reconstruction and surveillance culture result. After diagnosis of the infection, information was obtained about the time interval between IF and diagnosis and classification according to both the Willeneger and Roth and Makridis systems. Treatment modalities were grouped and analysed according to: use of antimicrobials, surgical debridement, nail removal or retention and spacer use. Cultures of bone or deep soft tissues were performed. Patients were followed up for 12 months, and outcomes (remission, relapse, death and loss of follow-up) were evaluated, as well as fracture consolidation. RESULTS: Remission was observed in 42.3% of patients. There was no significant association between any baseline variable and outcome. There was a significant association between Makridis stage 2 classification and recurrence or death. Treatment strategy was not significantly associated with outcome, and 65.4% of cases had positive culture results, with Enterobacter cloacae as the predominant agent. Consolidation was observed in 81.8% of patients and was not significantly related to the outcome. CONCLUSION: There was a significant association between Makridis classification and the outcome. Consolidation rate was not associated with the outcome regarding the treatment of the infection.

Evaluating the Antischistosomal Activity of Dehydrodieugenol B and Its Methyl Ether Isolated from Nectandra leucantha-A Preclinical Study against Schistosoma mansoni Infection.

Schistosomiasis, a parasitic disease affecting nearly 250 million individuals globally, poses a significant health challenge. With praziquantel being the sole available treatment and its limited efficacy in early stage infections, the identification of novel bioactive compounds becomes imperative. This study examines the potential of dehydrodieugenol B (1) and its methyl ether (2), derived from the leaves of the Brazilian Nectandra leucantha plant (Lauraceae), in combatting Schistosoma mansoni infections through a preclinical approach. Initially, compound 1 displayed noteworthy in vitro antiparasitic activity with an EC50 of 31.9 µM, showcasing low toxicity in mammalian cells and an in vivo animal model (Caenorhabditis elegans). Conversely, compound 2 exhibited no activity. In silico predictions pointed to favorable oral bioavailability and the absence of PAINS similarities. Subsequently, a single oral dose of 400 mg/kg of compound 1 or praziquantel was administered to mice infected with adult (patent infection) or immature parasites (prepatent infection). Remarkably, in prepatent infections, 1 resulted in a significant reduction (approximately 50%) in both worm and egg burden, while praziquantel reduced worm and egg numbers by 30%. The superior efficacy of dehydrodieugenol B (1) compared to praziquantel in premature infections holds the potential to advance the development of new molecular prototypes for schistosomiasis treatment.

Exploring hepatitis E virus seroprevalence and associated risk factors among the human population in Tandil, Buenos Aires, Argentina.

Background: Hepatitis E virus (HEV) infection is a common cause of acute clinical hepatitis worldwide and is emerging as a disease in Argentina. It is primarily transmitted through contaminated water and food, following the fecal-oral route. Furthermore, is a zoonotic disease with swine as the primary reservoir. Prevalence of HEV infection in humans in several regions of Argentina remains unknown. Objectives: (i) Determine the seroprevalence of HEV among the human population in Tandil, Buenos Aires, Argentina; (ii) Evaluate its association with demographic, socioeconomic and other risk exposures variables, and (iii) Describe and analyze spatial patterns related to HEV infection. Methods: From August 2020 to July 2021, serum samples were collected from 969 individuals aged 1-80 years. Seroprevalence and 95% Confidence Interval was determined. To assess the factors associated with the presence of anti-HEV antibodies, associations between the variables and seropositivity were evaluated through bivariate and multivariate analysis. Spatial scanning for clusters of positivity was carried out. Factors associated with these clusters were also assessed. Results: Anti-HEV antibodies were detected in 4.64% (IC 95% 3.27-6.02) of samples. Dark urine was associated with seropositivity (p = 0.02). Seropositivity was linked with the presence of natural water courses near their households (p = 0.02); the age (p = 0.04); and previous travel to Europe (p = 0.04). A spatial cluster of low rates of HEV seropositivity was detected, with greater distance of the households to water courses associated to the cluster, and male sex inversely associated to it. Discussion and conclusion: This study is the first study to investigate the prevalence of HEV in the population from Tandil, Buenos Aires, Argentina. Considering HEV infection in the differential diagnosis in individuals presenting acute hepatitis is highlighted. The incorporation of HEV testing into blood screening policies should be mandatory. Factors related to the infection and spatial patterns of high and low risk were determined, and should be considered when implementing specific preventive measures.

Inhibition of the norA gene expression and the NorA efflux pump by the tannic acid.

The NorA efflux pump of Staphylococcus aureus is known to play a major role in the development of resistance against quinolone drugs by reducing their concentration inside target pathogens. The objective of this study was to evaluate the ability of tannic acid to inhibit the gene expression of the NorA efflux pump in Staphylococcus aureus and to evaluate the in silico effect on the pump. Efflux pump inhibition was evaluated by fluorimetry. The checkerboard method evaluates the effect of the test substance in combination with an antimicrobial at different concentrations. To gene expression evaluation NorA the assay was performed using: a sub-inhibitory concentration preparation (MIC/4) of the antibiotic; a sub-inhibitory concentration preparation (MIC/4) of the antibiotic associated with tannic acid at a sub-inhibitory concentration (MIC/4). In this study, docking simulations were performed by the SWISSDOCK webserver. The ability of tannic acid to inhibit the NorA efflux pump can be related to both the ability to inhibit the gene expression of this protein, acting on signaling pathways involving the ArlRS membrane sensor. As well as acting directly through direct interaction with the NorA protein, as seen in the approach and in silico and in vitro per checkerboard method and fluorimetry of bromide accumulated in the cell.

Foi discutida a heterogeneidade de definições, critérios de identificação e instrumentos de avaliação encontrados. Destacam-se o pequeno número de relatos em comparação com a literatura internacional e a necessidade de tarefas padronizadas, validadas e sensíveis aos SDD no português brasileiro.(AU)

The present review aimed to explore the subtypes of developmental dyslexia (SDD), identified in the Brazilian literature, considering the heterogeneity in developmental dyslexia. This review included empirical studies in English or Portuguese, involving Brazilian students, and describing at least one SDD, along with diagnostic criteria. Searches were conducted in the Scielo, Pubmed and Google Scholar databases. The review identified 11 studies, which covered six different SDD. Phonological and surface dyslexia were the most commonly reported subtypes. The review discussed the variations in definitions, identification criteria, and evaluation instruments used in these studies. It also highlighted the limited number of reports in the Brazilian literature compared to international sources and emphasized the need for standardized, validated tasks in Brazilian Portuguese that are SDD-sensitive.(AU)

Esta revisión buscó responder cuáles los SDD se han identificado en el portugués brasileño. Se incluyeron estudios empíricos con participantes brasileños en inglés o portugués que describieran al menos un SDD y sus criterios de diagnósticos. Las búsquedas se realizaron en las bases de datos Scielo, Pubmed y Google Scholar. Como resultado, se encontraron 11 estudios relacionados con seis SDD, siendo las dislexias fonológicas y de superficie las más comunes, y se describieron las definiciones, criterios de identificación e instrumentos de evaluación utilizados en cada estudio. Se discutió la heterogeneidad de definiciones, criterios de identificación y herramientas de evaluación encontradas. Se destaca el escaso número de informes en comparación con la literatura internacional y la necesidad de tareas estandarizadas, validadas y sensibles a SDD en el portugués brasileño.(AU)

A proposed model to evaluate how changes in body condition score and the fatty acid profile of a supplement affect physiology and metabolic responses of nonlactating females.

Two experiments were designed to evaluate the effects of altering body condition score (BCS) and the profile of a fatty acid (FA) supplement on the metabolism of Bos indicus Nellore females. In experiment 1, 16 and 24 B. indicus heifers and nonlactating cows, respectively, were assigned to (1) maintenance diet (MNT-MNT; n = 10), (2) maintenance diet and BCS loss (MNT-LSS; n = 10), (3) maintenance diet supplemented with calcium salts of soybean oil for 30 d and BCS loss for 40 d (MNT+CFA-LSS; n = 10), and (4) maintenance diet for 30 d and BCS loss for 40 d with a diet containing calcium salts of soybean oil (MNT-LSS+CFA; n = 10). Following the BCS loss period, MNT-LSS, MNT+CFA-LSS, and MNT-LSS+CFA were fed a diet to promote the gain of BCS. In experiment 2, 40 Bos indicus nulliparous heifers were assigned to (1) maintenance diet (MNT-MNT; n = 10), (2) BCS loss followed by a BCS gain (LSS-REM; n = 10), (3) BCS loss followed by a BCS gain diet with CFA of palm oil (LSS-REM+PLM; n = 10), and (4) BCS loss followed by a BCS gain diet with CFA of soybean oil (LSS-REM+SOY; n = 10). Blood samples were obtained for serum haptoglobin and fecal samples for pH (experiment 2 only). In experiment 1, a treatment × day interaction was observed for BCS during the 60-d BCS loss and gain period. Animals assigned to MNT-MNT had a greater BCS than the other treatment groups on d 40 and 60 of the experiment, but no other differences were observed. Moreover, a treatment × day interaction was observed for serum haptoglobin, as on d 60, MNT-LSS had a greater mean serum haptoglobin concentration. In experiment 2, a treatment × day interaction was also observed for BCS. From d -4 to 0, LSS-REM and LSS-REM+SOY had a reduced BCS versus MNT-MNT, but also lower for LSS-REM versus MNT-MNT on d 1, and LSS-REM+PLM versus MNT-MNT on d -1 and 0. For serum haptoglobin, no treatment or treatment × day interaction was observed. A treatment × day interaction was observed for fecal pH. From d -10 to 0, MNT often had a lower fecal pH, but during realimentation, LSS-REM heifers had a reduced fecal pH on d 1, 4, and 10. In summary, we failed to demonstrate an increase in serum haptoglobin due to a BCS loss. Still, supplementation with calcium salts of FA alleviated the increase in haptoglobin and maintained fecal pH at more stable values during realimentation, regardless of the FA profile of the supplement.

Efeito imediato da mobilização com movimento (MWM) em pacientes com dor lombar: um estudo randomizado controlado / Immediate effect of mobilization with movement (MWM) in patients with low back pain: a randomized controlled trial

Objective: To analyze the effect of the Mobilization With Movement (MWM) of the Mulligan's concept in the perception of nociceptive and neuropathic pain, range of motion (ROM) and joint mobility of individuals with low back pain. Method: This is a randomized and controlled clinical trial, with 30 volunteers with nonspecific low back pain, divided into: Intervention Group (INTG), that received sustained natural apophyseal glides (SNAG) type MWM of the Mulligan's concept; Control Group (CONTG), which received a similar intervention to INTG. Volunteers were assessed using the Numeric Rating Scale for Pain (NRS Pain); the Modified Schober Test (MST) and ROM by goniometry for lumbar spine mobility and Douleur Neuropatique 4 (DN4) questionnaire for assessment of neuropathic and nociceptive pain. Results: INTG showed an increase in lumbar flexion (pre-intervention= 81.21±15.23°; post-intervention= 90.00±19.62°, p< 0.05), mobility of the lumbar spine in MST (pre= 15.33±1.05 post= 16.08±1.02, p< 0.05) and reduction of pain perception by NRS Pain (pre= 5.33±2.26; post= 1.47±2.61 p< 0.05) and in CONTG (pre= 4.07±2.34; post= 2.20±1.93, p< 0.05). Conclusion: The intervention with MWM - SNAGs promoted improved ROM and mobility in flexion of the lumbar spine, associated with reduction from the nociceptive pain in INTG and CONTG.

Objetivo: Analisar o efeito da Mobilization Whith Movement (MWM) do conceito Mulligan na percepção de dor nociceptiva e neuropática, na amplitude e na mobilidade articular de indivíduos com dor lombar. Métodos: Trata-se de um ensaio clínico randomizado e controlado, de 30 voluntários com dor lombar inespecífica, divididos em: Grupo Intervenção (GINT) que recebeu a mobilização articular com deslizamentos apofisários naturais mantidos (MWM - SNAGs); Grupo Controle (GCONT), que recebeu uma mobilização articular placebo. Os voluntários foram avaliados pela escala numérica de dor (EVN); pelo teste modificado de Schober (TMS) para a mobilidade da coluna lombar e pelo DN4 para avaliação da dor neuropática e nociceptiva. Resultados: GINT apresentou aumento da flexão lombar (pré intervenção= 81,21±15,23°; pós-intervenção= 90,00±19,62°, p= <0,05), da mobilidade da coluna lombar no TMS (pré= 15,33±1,05 pós= 16,08±1,02, p= <0,05) e redução da percepção de dor pela EVN (pré= 5,33±2,26; pós= 1,47±2,61= p< 0,05) e no GCONT (pré= 4,07±2,34; pós= 2,20±1,93, p < 0,05). Conclusão: A intervenção com MWM - SNAGs promoveu melhora da ADM e da mobilidade na flexão da coluna lombar, associada com redução da dor nociceptiva no GINT e no GCONT.
