Environmental enrichment interaction for laboratory beagle dogs used in research.

Experimental animal facilities can have a negative impact on the well-being of animals owing to confinement. To mitigate this, environmental enrichment (EE) is implemented confinement. The purpose of EE is to enhance the complexity of an animal's natural environment. The objective of this study was to identify the types of EE most enjoyed by dogs used in experimental research and housed in individual kennels. A total of six adult Beagle dogs, housed at the Laboratório de Quimioterapia Experimental em Parasitologia Veterinária (LQEPV) at the Universidade Federal Rural do Rio de Janeiro (UFRRJ) were included in the study. The EE tools used included Petball® toys, a grassy outdoor area, interaction with other dogs and with a team member, a "pool" made of plastic bottles, and dog's wet food ice cream. A team member assessed the usage of these tools every 5 min for a 30-min period, six times per day, one day per week, over the course of eight weeks. The study revealed that the grass area was the tool most commonly used for physical enrichment, accounting for 58% of the occurrences (p < 0.05). Social and food enrichment were enjoyed in second and third place, with 23% and 19% of occurrences, respectively. that the study findings suggest that dogs housed in individual kennels enjoy engaging in their natural behaviors.

Os animais de biotério podem viver em situações que afetem o seu bem-estar, como o confinamento. Um dos métodos que buscam para reduzir os impactos negativos é o Enriquecimento Ambiental (EA), o qual objetiva a promoção da complexidade do ambiente dos animais. Foi possível, com esta pesquisa, atingir o objetivo de identificar quais tipos de EA são mais aproveitados por cães utilizados em pesquisas experimentais que viviam em canis individuais. Foram utilizados seis cães adultos, Beagles, oriundos do Laboratório de Quimioterapia Experimental em Parasitologia Veterinária (LQEPV) da Universidade Federal Rural do Rio de Janeiro (UFRRJ). Como ferramentas de EA foram utilizados brinquedos Petball®, área de grama ao ar livre, interação com outros cães e com uma pessoa da equipe, "piscina" de garrafas plásticas e sorvete de ração úmida. Um membro da equipe avaliou o uso a cada 5 minutos, por período de 30 minutos (6 avaliações) por dia, um dia por semana ao longo de 8 semanas. O estudo revelou que a ferramenta mais usufruída pelos cães foi a área de grama através do enriquecimento físico, quantificado em 58% de ocorrência (p<0,05). Os enriquecimentos sociais e alimentar, foram usufruídos em segundo e terceiro lugar, com 23% e 19% de ocorrência, respectivamente. Pode-se concluir que os cães mantidos em canis individuais individualizados mais necessitam exercer seu comportamento natural específico, para que seu grau de bem-estar seja mantido em nível satisfatório e em consequência sua saúde mental.

Pharmacological treatment for obstructive sleep apnea: A systematic review and meta-analysis.

OBJECTIVE: Summarize the evidence on drug therapies for obstructive sleep apnea. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. PubMed, Embase, Scopus, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched on February 17th, 2023. A search strategy retrieved randomized clinical trials comparing the Apnea-Hypopnea Index (AHI) in pharmacotherapies. Studies were selected and data was extracted by two authors independently. The risk of bias was assessed using the Cochrane Risk of Bias tool. RevMan 5.4. was used for data synthesis. RESULTS: 4930 articles were obtained, 68 met inclusion criteria, and 29 studies (involving 11 drugs) were combined in a meta-analysis. Atomoxetine plus oxybutynin vs placebo in AHI mean difference of -7.71 (-10.59, -4.83) [Fixed, 95 % CI, I2 = 50 %, overall effect: Z = 5.25, p < 0.001]. Donepezil vs placebo in AHI mean difference of -8.56 (-15.78, -1.33) [Fixed, 95 % CI, I2 = 21 %, overall effect: Z = 2.32, p = 0.02]. Sodium oxybate vs placebo in AHI mean difference of -5.50 (-9.28, -1.73) [Fixed, 95 % CI, I2 = 32 %, overall effect: Z = 2.86, p = 0.004]. Trazodone vs placebo in AHI mean difference of -12.75 (-21.30, -4.19) [Fixed, 95 % CI, I2 = 0 %, overall effect: Z = 2.92, p = 0.003]. CONCLUSION: The combination of noradrenergic and antimuscarinic drugs shows promising results. Identifying endotypes may be the key to future drug therapies for obstructive sleep apnea. Moreover, studies with longer follow-up assessing the safety and sustained effects of these treatments are needed. PROSPERO REGISTRATION NUMBER: CRD42022362639.

Abstract Objective Associate demographic and work data and the empowering behavior of the nurse-leader from the perspective of nursing technicians and assistants. Methods Cross-sectional and correlational research carried out in a tertiary university hospital in the state of São Paulo. A total of 260 mid-level nursing professionals (nursing technicians and assistants) participated, using self-administered instruments from May to August 2021. To verify the association between the scale classes and the explanatory variables, a chi-square or Fisher's exact test was performed in the SAS program. Relationships were statistically significant if p<0.05. Results The profile of the participants was predominantly female, mean age 41.9 years, daytime workers, workload of 36.7 hours and satisfied with their work. The application of the Leader's Empowering Behavior instrument showed that the domain with the highest average of empowering behavior was "meaningful work" and the one with the lowest average was "autonomy in relation to bureaucracy". Nursing assistants and technicians who worked during the day did not have other work relationships and were satisfied with it, in addition to observing the leader's empowering behavior more. Conclusion Nurses' behavior to empower their team, from the perspective of technicians and nursing assistants in the studied hospital, was good in most domains, except in the domain "autonomy from bureaucracy", where it was reasonable. Working the day shift, not having other jobs and being satisfied with the job were aspects of greater empowerment.

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.

Intravenous Ceftriaxone on an Outpatient Basis in the Treatment of Ocular Syphilis.

PURPOSE: The goal of this study is to describe the clinical and laboratory outcomes of patients with syphilitic uveitis treated with 2 g intravenous Ceftriaxone daily on an outpatient treatment basis for 14 days, in the setting of the COVID pandemic and lack of hospitalization availability. METHODS: This study included a review of the clinical records from patients from January 2020 to December 2021 and who were then followed for 6 months at the Research Laboratory of Infectious Diseases in Ophthalmology of the National Institute of Infectious Diseases Evandro Chagas (INI) FIOCRUZ, Rio de Janeiro, Brazil. CONCLUSION: This study showed that almost all of the 15 patients were well treated for ocular syphilis with Ceftriaxone without any signs of therapeutic failure with documented clinical improvement and satisfactory decreasing VDRL titers.

Persistence of a carbapenem-resistant Acinetobacter baumannii (CRAB) International Clone II (ST2/IC2) sub-lineage involved with outbreaks in two Brazilian clinical settings.

BACKGROUND: Acinetobacter baumannii international clone II (IC2) is a widespread pandemic clone, however, it is rarely described in South America. The present study reported an outbreak caused by XDR IC2 strains in a clinical setting in Rio de Janeiro in 2022. METHODS: Molecular epidemiology analysis was conducted with MLST to determine the clonal relationship and to assign a sequence type. The antimicrobial resistance profile of A. baumannii strains was assessed by the disk-diffusion method and MIC determination, and the presence of antibiotic resistance genes was determined by PCR and Sanger sequencing. The whole genome of one representative strain (AB91) was sequenced to prospect its resistome and virulome. RESULTS: The MLST revealed that all strains belonged to the ST2 (Pasteur scheme) that corresponded to the pandemic IC2 lineage. They presented the XDR phenotype, which was compatible with their resistome composed of several acquired resistance genes and altered housekeeping genes. Additionally, an expressive virulome was revealed in AB91 genome. Genomic comparison with the unique other available IC2 genome from Brazil revealed that outbreaks occurring during (São Paulo - 2020/2021) and after (Rio de Janeiro - 2022) COVID-19 pandemics were caused by the same IC2 lineage. CONCLUSIONS: This study suggests that the presence of a huge arsenal of resistance and virulence genes may have contributed to the persistence and the successful establishment of IC2 in Brazilian clinical settings during and after the COVID-19 pandemics in response to a series of events, such as the antibiotic overused during that period.

Outbreak of high-risk XDR CRAB of international clone 2 (IC2) in Rio Janeiro, Brazil.

OBJECTIVES: Among the high-risk clones of Acinetobacter baumannii, called international clones (ICs), IC2 represents the main lineage causing outbreaks worldwide. Despite the successful global spread of IC2, the occurrence of IC2 is rarely reported in Latin America. Here, we aimed to evaluate the susceptibility and genetic relatedness of isolates from a nosocomial outbreak in Rio de Janeiro/Brazil (2022) and perform genomic epidemiology analyses of the available genomes of A. baumannii. METHODS: Sixteen strains of A. baumannii were subjected to antimicrobial susceptibility tests and genome sequencing. These genomes were compared phylogenetically with other IC2 genomes from the NCBI database, and virulence and antibiotic resistance genes were searched. RESULTS: The 16 strains represented carbapenem-resistant A. baumannii (CRAB) with an extensively drug-resistant profile. In silico analysis established the relationship between the Brazilian CRAB genomes and IC2/ST2 genomes in the world. The Brazilian strains belonged to three sub-lineages, associated with genomes from countries in Europe, North America, and Asia. These sub-lineages presented three distinct capsules, KL7, KL9, and KL56. The Brazilian strains were characterised by the co-presence of blaOXA-23 and blaOXA-66, in addition to the genes APH(6), APH(3"), ANT(3"), AAC(6'), armA, and the efflux pumps adeABC and adeIJK. A large set of virulence genes was also identified: adeFGH/efflux pump; the siderophores barAB, basABCDFGHIJ, and bauBCDEF; lpxABCDLM/capsule; tssABCDEFGIKLM/T6SS; and pgaABCD/biofilm. CONCLUSION: Widespread extensively drug-resistant CRAB IC2/ST2 is currently causing outbreaks in clinical settings in southeastern Brazil. This is due to at least three sub-lineages characterised by an enormous apparatus of virulence and resistance to antibiotics, both intrinsic and mobile.

Comparison of efficiency of different self-assessment instruments for screening dysphonia. / Comparação da eficiência de diferentes instrumentos de autoavaliação para o rastreio da disfonia.

PURPOSE: To compare the efficiency of different vocal self-assessment instruments for dysphonia screening. METHODS: 262 dysphonic and non-dysphonic individuals participated in the research. The mean age was 41.3 (±14.5) years. The diagnosis of dysphonia was based on the auditory-perceptual analysis of the sustained vowel "é" and on laryngological diagnosis. The responses of the instruments were collected: Voice-Related Quality of Life (V-RQOL), Voice Handicap Index (VHI), VHI-10, Voice Symptoms Scale (VoiSS), and the Brazilian Dysphonia Screening Tool, (Br-DST) called in Brazilian Portuguese Instrumento de Rastreio da Disfonia (IRDBR). To analyze assertiveness in relation to the presence of dysphonia, the cutoff points of each instrument and the decision rule recommended by the IRDBR were used. An exploratory analysis was performed to compare mean scores of instruments and verify associations between variables. RESULTS: The instruments evaluated were sensitive to capture the impact of dysphonia in a similar way regardless of professional voice use and type of dysphonia. There was a difference only in VoiSS scores for the variable gender, with a higher score for females. Regarding global assertiveness, the instruments showed high rates of success in classification, with emphasis on the VoiSS, which had the highest rate (86.3%), followed by the IRDBR (84.0%), VQL (80.9%), VHI (78.2%), and VHI-10 (75.2%). CONCLUSION: The VoiSS has the highest assertiveness index in the identification of dysphonia, followed by the IRDBR. The IRDBR is a short, simple, and easy-to-apply tool for screening procedures.

Inclusão tecnológica: efeitos na saúde mental e qualidade de vida de idosos / Technological inclusion: effects on the mental health and quality of life of elders

Avaliar o efeito de um treinamento em tecnologia digital para idosos da comunidade. Trata-se de um estudo intervencional quase experimental. A amostra foi composta por 12 idosos de ambos os sexos, residentes em Maringá (PR). O estudo ocorreu nas instalações de uma instituição de ensino superior e teve duração de oito semanas, totalizando 32 horas. O protocolo de avaliação e reavaliação consistiu em: coleta dos dados sociodemográficos; aplicação da Escala de Depressão Geriátrica ­ Geriatric Depression Scale (GDS); e aplicação de dois questionários de qualidade de vida (WHOQOL-OLD e WHOQOL-BREF). Verificou-se diferença significante entre os momentos pré-intervenção e pós-intervenção no domínio Psicológico (p=0,032) e na faceta Autonomia (p=0,032) da qualidade de vida. O treinamento para a inclusão digital de idosos com o uso de smartphone pode contribuir para melhora da qualidade de vida dos idosos quanto aos aspectos da saúde mental.

To evaluate the effect of training in digital technology for community elders. This is a quasi-experimental interventional study. The sample consisted of 12 elderly people of both sexes, living in Maringá (PR). The study took place at the premises of a higher education institution and lasted eight weeks, totaling 32 hours. The assessment and reassessment protocol consisted of: collecting sociodemographic data; application of the Geriatric Depression Scale (GDS); and application of two quality of life questionnaires: WHOQOL-OLD and WHOQOL-BREF. There was a significant difference between the pre- and post-intervention moments in the psychological domain (p=0.032) and in the autonomy facet (p=0.032) of quality of life. Training for the digital inclusion of the elderly with the use of smartphones can contribute to improving the quality of life of the elderly in terms of mental health aspects.

Clinical-epidemiological profile of confirmed cases of osteoarticular tuberculosis.

Introduction: tuberculosis (TB) remains a major cause of morbidity and mortality worldwide. The incidence of TB has increased since the 1980s. Given the increasing prevalence of TB worldwide, osteoarticular TB (OATB) is a significant health problem. Methods: retrospective study of a case series of hospitalized patients with confirmed OATB by culture or histopathological examination who were seen at a reference orthopedic hospital in São Paulo, Brazil, from 2014 to 2019. Results: thirty patients with confirmed bone and joint TB were seen from 2014 to 2019. The main sites of OATB were the spine (83.3 %) and the appendicular skeleton (26.7 %). Indication of surgical treatment was significantly related to the need for hospitalization ( p = 0.009 ) and the increased length of hospital stay ( p = 0.005 ). Presence of sequelae at the end of treatment was correlated with the presence of motor deficit at the time of OATB diagnosis ( p = 0.035 ) as well as with initial presence of functional limitation ( p = 0.025 ) and with high value of C-reactive protein at the end of treatment ( p = 0.037 ). Conclusions: the delay in the onset of clinical and laboratory signs of cases of osteoarticular infections hinders the early diagnosis and treatment of the disease, resulting in major complications sometimes requiring surgical treatment and consequently leading to a prolonged hospital stay, evidence of high inflammatory activities, and the presence of neurological deficits.

Experience with SARS-CoV-2 in an orthopaedic hospital.

Background: Concerns about nosocomial transmission of SARS-CoV-2 have been described since the COVID-19 pandemic was first reported and cases of hospital-acquired (HA) COVID-19 and COVID-19 outbreaks have been reported even in clinical areas not intended for the specific care of COVID-19 and declared as "non-COVID" areas. Methods: Retrospective analysis of measures to prevent of hospital acquisition of COVID-19 in patients admitted to a tertiary referral specialist orthopaedic hospital in Brazil in which emergency care was maintained during the pandemic. Results: The proportion of HA-COVID-19 (0.07%) was lower than the value reported for general healthcare in Brazil (0.72%, P<0.001). The integration of several clinical teams to maintain a constant surveillance system, as well as the immediate isolation of patients with any compatible symptoms of COVID-19 and the restriction from work and the testing of symptomatic healthcare workers, were an important part of the strategies adopted. Conclusion: We suggest that the described strategies for preventing the nosocomial spread of SARS-CoV-2 contributed to the observed proportion of HA-COVID-19 to be significantly lower than the reported national value. Future studies that investigate these and other preventative measures are important so that hospitals are prepared for further periods of a high incidence of COVID-19, as well as for other epidemics associated with respiratory transmission.

Bivariate GWAS reveals pleiotropic regions among feed efficiency and beef quality-related traits in Nelore cattle.

Feed-efficient cattle selection is among the most leading solutions to reduce cost for beef cattle production. However, technical difficulties in measuring feed efficiency traits had limited the application in livestock. Here, we performed a Bivariate Genome-Wide Association Study (Bi-GWAS) and presented candidate biological mechanisms underlying the association between feed efficiency and meat quality traits in a half-sibling design with 353 Nelore steers derived from 34 unrelated sires. A total of 13 Quantitative Trait Loci (QTL) were found explaining part of the phenotypic variations. An important transcription factor of adipogenesis in cattle, the TAL1 (rs133408775) gene located on BTA3 was associated with intramuscular fat and average daily gain (IMF-ADG), and a region located on BTA20, close to CD180 and MAST4 genes, both related to fat accumulation. We observed a low positive genetic correlation between IMF-ADG (r = 0.30 ± 0.0686), indicating that it may respond to selection in the same direction. Our findings contributed to clarifying the pleiotropic modulation of the complex traits, indicating new QTLs for bovine genetic improvement.

Characterization of Dermatoglyphic Profiles and its Relation to Acoustic Measures in Voice Professionals.

INTRODUCTION: Acoustic analysis is widely used for assessing and monitoring vocal function. Dermatoglyphics is a method that analyzes genetic fingerprint markers, and uses that information for predicting physical skills related to anaerobic (explosive strength and speed) and aerobic (motor coordination and resistance) mechanisms. Therefore, it can be used as an indicator for individualized vocal training. OBJECTIVE: To characterize the dermatoglyphic profiles and their relation to acoustic measures in voice professionals. METHODS: A cross-sectional study involving 79 voice professionals. Acoustic analysis was performed using the PRAAT software. Mean intensity, fundamental frequency (F0), and cepstral peak prominence (CPP) value were extracted from the sustained vowel /a/. Fingerprints were collected using a Watson mini-integrated biometric scanner, and were quantified by design predominance, delta index (D10), total ridge count (TRC), and dermatoglyphic profile. The acoustic measures were analyzed descriptively and compared, considering the subjects' dermatoglyphic profiles. The confidence levels ranged from 90% to 95%. RESULTS: Most subjects exhibited anaerobic dermatoglyphic profiles (P = 0.004) and low TRC (p < 0.001). Higher F0 (P = 0.061), intensity (P = 0.065), and CPP (P = 0.073) were found for anaerobics (P < 0.001). There was a weak and negative correlation between TRC and intensity (P = 0.026), as well as between F0 (P = 0.017) and CPP (P = 0.069). CONCLUSION: Anaerobic profiles were predominant. The values of F0, intensity, and CPP increased for the anaerobics. There was a weak negative correlation between the TRC and intensity, F0, and CPP measures. Dermatoglyphics could have been seen as an interesting tool in the voice assessment and training direction for voice professionals.

Brazilian Dysphonia Screening Tool (Br-DST): An Instrument Based on Voice Self-Assessment Items.

OBJECTIVE: To propose a short instrument for the screening of dysphonia in the Brazilian population through the investigation of traditional voice self-assessment instrument items. METHODS: We analyzed the medical records of 139 individuals with an average age of 37.4 years and a minimum and maximum age of 18 and 77 years, respectively. The participants were classified as dysphonic (D) or non-dysphonic (ND) according to an analysis of the combination of vocal complaints and laryngological reports. Responses to the items of the following self-assessment instruments were collected: the Questionário de Qualidade de Vida em Voz - QVV (Voice-Related Quality of Life - V-RQOL), the Índice de Desvantagem Vocal - IDV (Voice Handicap Index - VHI) and the Escala de Sintomas Vocais - ESV (Voice Symptom Scale - VoiSS). These items were analyzed regarding their predictive capacities for dysphonia through logistic regression models. RESULTS: The model containing items of the QVV was not observed to be valid. The model for the IDV produced a set of three items (10, 13, and 14), and the ESV model showed two items (4 and 20) to be significant. A Global model combining the previous models shows that items I feel as though I have to strain to produce voice from the IDV and "Is your voice hoarse?" from the ESV are the most significant in the classification of the presence of dysphonia. This decision-making model was considered the most efficient to identify the dysphonia, with the highest level of accuracy compared to the other models investigated (83.4%). CONCLUSION: Dysphonia screening can be performed using a simple, rapid protocol with a high-efficiency index that includes two items taken from traditional voice self-assessment instruments.

Influence of COVID-19 pandemic on molar pregnancy and postmolar gestational trophoblastic neoplasia: An observational study.

OBJECTIVE: To assess whether the incidence and aggressiveness of molar pregnancy (MP) and postmolar gestational trophoblastic neoplasia (GTN) changed during the COVID-19 pandemic. DESIGN: Observational study with two separate designs: retrospective multicentre cohort of patients with MP/postmolar GTN and a cross-sectional analysis, with application of a questionnaire. SETTING: Six Brazilian Reference Centres on gestational trophoblastic disease. POPULATION: 2662 patients with MP/postmolar GTN treated from March-December/2015-2020 were retrospectively evaluated and 528 of these patients answered a questionnaire. METHODS: Longitudinal retrospective multicentre study of patients diagnosed with MP/ postmolar GTN at presentation and a cross-sectional analysis, with application of a questionnaire, exclusive to patients treated during the period of study, to assess living and health conditions during the COVID-19 pandemic compared with previous years. MAIN OUTCOME MEASURES: The incidence of MP/postmolar GTN. RESULTS: Compared with the last 5 pre-pandemic years, MP/postmolar GTN incidence remained stable during 2020 (COVID-19 pandemic). Multivariable logistic regression, adjusted for the patient age, showed that during 2020, presentation with MP was more likely to be >10 weeks of gestation (adjusted odds ratio [aOR] 2.50, 95% confidence interval [CI] 1.90-3.29, P < 0.001), have a pre-evacuation hCG level ≥100 000 iu/l (aOR 1.77, 95% CI 1.38-2.28, P < 0.001) and time to the initiation of chemotherapy ≥7 months (aOR 1.86, 95% CI 1.01-3.43, P = 0.047) when compared with 2015-2019. CONCLUSIONS: Although the incidence of MP/postmolar GTN remained stable during the COVID-19 pandemic in Brazil, the pandemic was associated with greater gestational age at MP diagnosis and more protracted delays in initiation of chemotherapy for postmolar GTN.
