Thermoregulatory response of black or red lactating Holstein cows in the hot and cold season in southern Brazil.

Dairy cows in pasture-based systems are more susceptible to heat stress. Holstein cows have the black or red phenotypes, the latter having lower absorbance of solar radiation. Therefore, the study's objective was to evaluate whether cows with red (R) coats are more resistant than black (B) cows to hot weather in a subtropical climate. R and B lactating Holstein cows were evaluated during the cold and hot seasons for internal and surface temperature and sweating rate. In the cold season, body temperature (n = 9/group) did not differ between groups, but the average superficial temperature (n = 13/group) was lower in R cows (B: 30.9 ± 0.3 °C; RW: 29.6 ± 0.3 °C; p = 0.02). In the hot season, under mild to moderate heat stress, mean body temperature (n = 9/group) of R cows was lower (B: 38.75 ± 0.01 °C; R: 38.62 ± 0.1 °C; p=<0.0001), whereas no difference was observed in superficial temperature (n = 17/group). The maximum internal temperature and sweating rate (n = 11/group), measured in the hot season, and the number of evaluations in hyperthermia in both seasons did not differ. Therefore, there were differences in thermoregulation between phenotypes under mild to moderate heat stress conditions. However, considering that only discrete differences were observed, the red and white coat is unlikely to benefit the Holstein cow's welfare under mild to moderate thermal stress.

Transitional care for older persons with need of geriatric rehabilitation nursing interventions.

BACKGROUND: The literature review notes that people in need of care from Rehabilitation Programs do not always see their continuity ensured. OBJECTIVE: This study aim to analyze the perspective of Specialists Nurse in Rehabilitation Nursing in relation to the organization and specialized intervention of transitional care for older people in need of rehabilitation programs. METHODS: This is a qualitative study within the interpretivist paradigm. A focus group with 8 nurses and 13 interviews with Portuguese nurses were carried out between April 2022 and February 2023. Content analysis was carried out. RESULTS: The triangulation of the data made it possible to identify 3 categories: Coordination of a transitional care program; Empowering the person to self-manage the transitional care process and Empowering the Informal Caregiver. CONCLUSIONS: It is imperative to promote the coordination of transitional care, increase the functional capacity of the person and empower the informal caregiver.

Opportunistic Use of Computed Tomography to Determine Muscle-Adipose Ratio Reliably Predicts Wound Complications After Kocher-Langenbeck Surgical Exposure of the Acetabulum.

OBJECTIVES: To determine whether muscle-to-adipose ratio (MAR) along the course of a Kocher-Langenbeck incision is more accurate at predicting postoperative wound complications after acetabular fixation than waist-to-hip ratio or body mass index (BMI). DESIGN: Retrospective case series. SETTING: Level 1 Trauma Center. PATIENT SELECTION CRITERIA: Patients who sustained an acetabular fracture and had fixation through a Kocher-Langenbeck approach from January 1 st , 2008 to December 31 st , 2018. For inclusion, patients had to have a pre-operative and a post-operative CT of the pelvis and a minimum follow up of 12 months. Patients were excluded if an antibiotic other than cefazolin was administered for prophylaxis, if they had a femur fracture treated with an antegrade intramedullary nail, if there was any associated pelvic ring injury requiring surgical treatment of any type, if there were any abdominal or pelvic procedures completed by another surgical service, if the patient underwent pelvic embolization of a vessel, if there was presence of a genitourinary injury or Morel-Lavallée lesion, or if there was a subsequent surgical procedure unrelated to the primary endpoint (e.g., revision fixation). OUTCOME MEASURES AND COMPARISONS: Presence of a surgical site infection or a wound healing complication. BMI, WHR and MAR were evaluated and compared for their ability to predict a surgical site infection or a wound healing complication. RESULTS: One-hundred ninety-three patients were included in this study, and the mean follow-up was 17.4 months. Thirty patients (15.5%) developed a wound complication. Seventeen patients (8.8%) developed a superficial infection and 13 (6.7%) developed a deep infection. The mean BMI for those who developed a wound complication was 35.9. The mean MAR was 0.67 for patients who developed a wound complication versus 0.75 for those who did not. Receiver operator characteristic analysis showed an area under curve for BMI to be 0.717 (95% confidence interval [CI] 0.577-0.857, P = 0.006) and for MAR to be 0.680 (inverted, 95% CI, 0.507-0.854, P = 0.022). The area under curve for waist-to-hip ratio was not statistically significant. CONCLUSIONS: MAR is a significant predictor of postoperative wound complication in patients undergoing treatment of posterior wall acetabular fractures. The higher rate of wound complications in patients with a low MAR should be considered in the treatment of these patients and may be used to guide discussion regarding the risks of surgery and the potential use of adjuncts to reduce wound healing complications. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Impact of family-centered care in families with children with intellectual disability: A systematic review.

Background: Family-Centered Care (FCC) is an approach to healthcare planning, delivery and evaluation, based on beneficial partnerships between health professionals, patients and families. FCC may be particularly relevant for families with children with intellectual disability (ID), given their needs of continuum care. Objective: To identify which components of the FCC are practiced and which health outcomes are considered effective in families with children with ID. Method: A systematic review guided by the PRISMA STATEMENT 2020 approach and the STROBE reporting guidelines was performed on specific databases through the EBSCOhost Web platform: MEDLINE with Full Text, CINAHL PLUS with Full Text, Academic Search Complete and Psychology and Behavioral Sciences Collection. Peer-reviewed articles published in English or Portuguese languages from 2018 to September 2023 were retrieved. Methodological quality was established using the Quality Assessment Tool for Observational, Cohort and Cross-Sectional Studies - NHLBI, NIH. Results: Ten studies met the eligibility criteria and were synthetized. The results revealed nine components, reflecting the way FCC was developed: shared decision-making; family education; respect for culture; family engagement; recognition of the family's needs, characteristics and interests; specialized care support; social and emotional support; family functionality; and family seen as a unit. The health outcomes demonstrate effective gains in improving children's health through family satisfaction with health services. Also achieved psychological and social benefits, with improved family well-being and quality of life, favoring family empowerment. Conclusions: The evidence suggests that FCC components involves an effective partnership between the family and health professionals as the main key in developing care plans, as well as the experience that the family unit brings to the delivery of care. FCC approach include all family members as decision-makers, providing emotional, physical and instrumental levels of support. Health outcomes emerged in three strands; for children with ID, families and health services.

Programmes Addressed to Informal Caregivers' Needs: A Systematic Literature Review.

BACKGROUND: Addressing informal caregivers' needs is essential for ensuring quality healthcare and promoting citizen-centred care. This systematic review assessed current knowledge about programmes aimed at meeting the needs of informal caregivers of adults who are dependent on others for daily life activities. METHODS: Following the PRISMA guidelines, the electronic databases EBSCOhost Research Platform, MEDLINE, CINAHL, Scopus, Web of Science and The Virtual Health Library were searched for randomized experimental studies published between 2012 and 2022 that implemented programmes addressing informal caregivers' needs to improve their experiences, health, and well-being. Quality was assessed using the standardized critical evaluation tools from the Joanna Briggs Institute. Two independent investigators performed the eligibility assessment and data extraction. Quantitative data on the effectiveness of interventions were collected, and the content of each intervention was synthesized and aggregated into categories, through narrative synthesis. RESULTS: The majority of the included studies (n = 16) were conducted in European countries and implemented a structured intervention programme compared to the provision of usual care. The studies were of fair to high methodological quality, with a higher risk of bias related to blinding. The results supported the achievement of favourable health outcomes among informal caregivers, namely improvements in mental health (n = 3) and quality of life (n = 3) and a decrease in psychological symptomatology (n = 5) and burden (n = 3). None of the interventions reported adverse outcomes; however, five studies did not describe significant differences in the outcomes assessed after the implementation of the programmes. Interventions focusing on training and educating caregivers (n = 14) and cognitive-behavioural strategies (n = 7) were the most common, while programmes focusing on emotional and psychological support as a resource to improve caregivers' psychological outcomes were scarce. CONCLUSIONS: This systematic review adds to the growing body of evidence and insight showing that programmes that address informal caregivers' needs seem to contribute to better physical and psychological health outcomes through the promotion of caregivers' educational support and the implementation of cognitive-behavioural strategies. Future research should implement methodologically robust cross-country programmes tailored to informal caregivers' physical, emotional, psychosocial, societal, and educational needs throughout the care trajectory.

Does GnRH treatment at TAI regardless of estrus occurrence increase pregnancy rate in crossbred Bos taurus suckled cows?

The impact of GnRH treatment on the day of TAI in beef cows has received limited investigation, especially concerning its association with estrus expression. Consequently, two experiments were conducted to assess the potential of GnRH treatment on the day of TAI to enhance fertility according to the expression or not of estrus in beef cows. Experiment 1 aimed to determine ovulation rate and luteal function, while Experiment 2 aimed to determine the effect of the two GnRH treatment approaches on pregnancy rate. In Experiment 1, multiparous Brangus suckling cows (n = 17) were submitted to an 8-day TAI protocol. Estrus occurrence was evaluated based on chalk removal on D10 (TAI) and cows were assigned to receive GnRH (25µg lecirelin; im) according to the group: GnRH (n = 7), regardless of estrus expression; or selectGnRH (n = 10), only cows not detected in estrus. Ovulation rate occurring until 77h after IVD removal did not differ (p = 0.17) between GnRH (85.7%; 6/7) and selectGnRH (100%; 10/10). Also, corpus luteum size and serum progesterone concentration were not affected (p>0.05) by treatments. In Experiment 2, crossbred taurine suckled cows (n = 384) were submitted to the same protocol as described in Experiment 1 and were randomly allocated to GnRH or selectGnRH groups. There was no difference in P/AI between groups (selectGnRH = 55.6%; GnRH = 54.3%; p = 0.7) 30 days after TAI. As expected, there was a pronounced effect (p<0.0001) of estrus expression on P/AI (Estrus = 61.5%; No estrus = 33.0%), regardless of group. In summary, ovulation timing and rate and luteal function did not differ between groups. Also, GnRH administration only in cows that do not show estrus is recommended, considering hormone savings and similar conception rate.

Is it possible to replace eCG by GnRH in the hormonal protocol for timed artificial insemination in ewes during the breeding season?

Hormonal protocols based on progestogens and equine chorionic gonadotrophin (eCG) are efficient for estrus and ovulation synchronization in ewes. Although eCG is indispensable during seasonal anestrus, it may not be necessary during the breeding season. Thus, we tested the hypothesis that GnRH is effective in replacing eCG during the breeding season allowing satisfactory ovulation rate, luteal function and conception rates after timed artificial insemination (TAI). Ewes (n = 134) with a minimum body condition score of 2.5 (0-5 scale) were treated with intravaginal devices (IVD) containing 60 mg of medroxyprogesterone acetate (MPA) for seven days and received 0.26 mg of sodium cloprostenol at the time of IVD removal. In Exp. 1, at IVD removal, ewes (n = 29) were allocated to three groups: eCG (200 IU at IVD removal; n = 10); eCG+GnRH (200 IU eCG at IVD removal and 4 µg of buserelin 36 h later; n = 10); or GnRH (buserelin 36 h after IVD removal; n = 9). Blood samples were collected 2, 6 and 12 days after TAI moment (54 h after IVD removal), for progesterone (P4) analysis. In Exp 2, the ewes were allocated to eCG (n = 10) or GnRH (n = 10) groups, as above described, and ovulation moment was evaluated 54, 66 and 78 h after IVD removal. In Exp 3, TAI was performed in ewes from eCG (n = 45) and GnRH (n = 40) groups using 100 × 106 motile spermatozoa from a pool of semen collected from four rams. In Exp. 1, based on P4 levels, we confirmed that all the ewes ovulated (29/29) and there was no significant effect of group (P = 0.89) or group x day (P = 0.18) on P4 concentration, being observed a significant effect of day (P = 0.0001). In Exp. 2, the maximum DF diameter (P = 0.26) and ovulation moment (P = 0.69) did not differ between groups. In Exp. 3, pregnancy rate was significantly lower (P = 0.02) in GnRH (22.5 %; 9/40) compared to eCG (46.7 %; 21/45). The results indicate that, although ovulation and luteal function were not altered after eCG, eCG+GnRH or GnRH treatment, GnRH alone before TAI cannot be used to replace eCG treatment during the breeding season.

The Perspective of Rehabilitation Nurses on Physical Exercise in the Rehabilitation of Older People in the Community: A Qualitative Study.

In the face of an increasingly aging population, nurses have to design and implement programs aimed at the elderly in order to keep them healthy and maintain their quality of life. Structured physical exercise and overall physical activity play a major role in maintaining an active lifestyle, improving health, preventing disease, and helping to maintain older people's quality of life. To investigate the importance of implementing physical exercise programs for the older person in the community, taking into account the perspective of the rehabilitation nurse specialist, this is a qualitative, exploratory, and descriptive study with nine rehabilitation nurses from various regions of Portugal who have experience of implementing physical exercise programs with the elderly. This study used semi-structured interviews, one of the most common data collection procedures in social and health research. Content analysis was used to analyze the data. The study received a positive opinion from the Ethics Committee. The participants' perspectives focused on the following subjects: "Physical exercise program for the elderly in the community", "Importance of physical exercise in the rehabilitation of the elderly in the community", "People's adherence to the programs", "Gains in health resulting from the implementation of these strategies" and "Gains from group activities". A set of indicators emerged from the analysis. Nurses recognize the importance of using structured physical exercise programs adjusted to the rehabilitation of the older person, with gains in promoting active and healthy aging.

"Pra nós que somos negras, tudo é mais difícil". Cartografia de uma mulher negra em sofrimento psíquico / "For us who are black, everything is more difficult". Cartography of a black woman in psychological distress

Resumo O estudo tem como objetivos: cartografar a trajetória de racismo estrutural e de sofrimento psíquico de uma mulher negra acompanhada por uma enfermaria psiquiátrica em um Hospital Geral; e refletir sobre a relação entre o racismo estrutural e sofrimento psíquico. O racismo é a operacionalização tecnológica, destinada ao exercício do biopoder, que coloca negros em posições inferiores, determinando desvantagens a partir da raça. A violência racista impõe o debate para o campo da saúde mental por sua influência no sofrimento psíquico. Pesquisa qualitativa, descritiva e exploratória, com abordagem cartográfica, por meio da trajetória de uma usuária-cidadã-guia, utilizando-se da entrevista semiestruturada e do diário de campo cartográfico. A analise fez emergir as cenas: ser negra e como a sociedade nos vê; auto ódio; solidão da mulher negra, que demonstram como o sofrimento psíquico é influenciado pelo racismo estrutural que condicionam a existência do negro ao menor valor, à estigmatização e à desumanização. A subjetividade produzida internaliza sentimentos de inferioridade, de solidão, de auto-ódio e de não lugar. Torna-se urgente a problematização da questão racial na produção do cuidado em saúde mental, bem como uma reforma societária que proporcione a existência plena de direitos e de dignidade das pessoas negras.

Abstract The study aims to map the trajectory of structural racism and psychic suffering of a black woman accompanied by a psychiatric nursery in a General Hospital; and to reflect on the relationship between structural racism and psychic suffering. Racism is the technological operationalization, destined to the exercise of biopower, which places black people in inferior positions, determining disadvantages based on race. Racist violence imposes the debate on the field of mental health due to its influence on psychic suffering. Qualitative, descriptive and exploratory research, with a cartographic approach, through the trajectory of a user-citizen-guide, using a semi-structured interview and a cartographic field diary. The analysis made the scenes emerge: being black and how society sees us; self-hate; and loneliness of black women that demonstrate how psychic suffering is influenced by structural racism that condition the existence of black people to the lowest value, stigmatization and dehumanization. The subjectivity produced internalizes feelings of inferiority, loneliness, self-hatred and non-placement. It is urgent to problematize the racial issue in the production of mental health care, as well as a societal reform that provides the full existence of rights and dignity of black people.

Prostaglandin F2α treatment concurrent with artificial insemination does not affect bovine embryo production / Administração de prostaglandina F2 alfa no momento da inseminação artificial não afeta a produção de embriões bovinos

Treatment with prostaglandin F2α (PGF) induces ovulation and increases conception rates in cows, while improving embryo production in buffalos. However, its effect on superovulated cows is unknown. This study verified whether single PGF administration concurrent with artificial insemination (AI) improves fertilization and embryo production rates in superovulated cows. In each replicate, embryo donor cows were equally allocated to two groups: the untreated control and PGF groups. The latter of which received 482 µg of cloprostenol concurrent with the first AI. Each cow (n = 35) was subjected to two superovulations (SOV) in a crossover design (total = 70 embryo collections). In the control and PGF groups, respectively, the observed responses were [median (95% CI)]: 12 (10-18) and 15 (12-18) total structures, 9 (7-11) and 7 (6-10) viable embryos, 1 (0-1) and 1 (1-3) degenerated embryos, and 1 (0-3) and 2 (0-5) oocytes (P > 0.05). In conclusion, single PGF treatment concurrent with the first AI did not affect embryo production in superovulated cows.

A prostaglandina F2α (PGF) pode induzir a ovulação e melhorar tanto a concepção em vacas, como a produção de embriões em búfalas, mas o efeito em vacas superovuladas é desconhecido. Esse estudo teve como objetivo verificar se a administração de uma dose de PGF na inseminação artificial (IA) após a superovulação (SOV) melhora as taxas de fecundação e produção embrionária em vacas. Em cada replicação, vacas doadoras de embriões foram equilibradamente alocadas em dois grupos: controle, não tratado, ou PGF, que recebeu 482 µg de cloprostenol no momento da primeira IA. Cada doadora (n = 35) foi submetida a duas SOV em um delineamento crossover (total = 70 coletas de embriões). Nos grupos controle e PGF, respectivamente, foram observados [medianas (IC 95%)]: 12 (10-18) e 15 (12-18) estruturas totais; 9 (7-11) e 7 (6-10) embriões viáveis; 1 (0-1) e 1 (1-3) embriões degenerados; e 1 (0-3) e 2 (0-5) ovócitos (P > 0,05). Conclui-se que uma única administração de PGF no momento da primeira IA não afeta a produção embrionária de vacas superovuladas.

Desafios e perspectivas na produção comercial de embriões in vivo e in vitro de raças taurinas e sintéticas / Current challenges and perspectives of in vivo and in vitro commercial embryo production of taurine and synthetic breeds

As biotécnicas de produção in vivo e in vitro de embriões bovinos permitem aumentar significativamente o número de descendentes de fêmeas genética e/ou zootecnicamente importantes. Porém, antes de se optar por um dos métodos, deve-se avaliar suas peculiaridades. A produção in vivo pode ser empregada de forma satisfatória tanto em zebuínos quanto em raças sintéticas e taurinas, permitindo a obtenção de, em média, seis a sete embriões viáveis por coleta, com boa tolerância à criopreservação. Já a produção in vitro é mais eficiente em raças zebuínas e sintéticas, visto que possuem maior número de folículos antrais aspiráveis. Além disso, esta técnica permite a produção de embriões sem estímulos hormonais exógenos, porém com menor criotolerância. Desse modo, a presente revisão discute os desafios atuais e perspectivas futuras na produção de embriões in vivo e in vitro com base nos dados da rotina de uma central de doadoras e laboratório de produção de embriões que desenvolve simultaneamente ambas as técnicas de produção de embriões na região Sul do Brasil.(AU)

Biotechniques for in vivo and in vitro production of bovine embryos allow to significantly increase the number of descendants from cows genetically and/or zootechnically superior. However, before opting for one of the methods, one should evaluate its peculiarities. In vivo production can be used satisfactorily both in zebu cattle and in synthetic and taurine breeds, allowing to obtain, on average, six to seven viable embryos per procedure, with good tolerance to cryopreservation. In vitro production is more efficient in Zebu and synthetic breeds, since they have a greater number of aspirable antral follicles. In addition, this technique allows the production of embryos without exogenous hormonal stimuli, but with lower cryotolerance. This review discusses current challenges and future perspectives in in vivo and in vitro embryo production based on routine data from an embryo production center and a laboratory that develop, simultaneously, the two embryo production techniques in southern Brazil.(AU)

Clinical-epidemiological profile of traumatic brain injury associated with traffic accidents in southeastern Pará, in the Brazilian Amazon / Perfil clínico-epidemiológico de traumatismos cranioencefálicos associados a acidentes de trânsito no Sudeste do Pará, na Amazônia brasileira

Introduction: In Brazil, traumatic brain injury (TBI) represents about two thirds of all causes of death and are often associated with traffic accidents, causing overload of medium and high complexity services. Objectives:To describe the occurrence and clinical-epidemiological profile of TBIs associated with traffic accidents in a regional hospital in the southeast of the state of Pará. Materials and Methods: This is a cross-sectional analytical study. It was based on data from the medical and statistical archives service of a regional hospital, through the analysis of electronic medical records of patients treated with TBI resulting from traffic accidents in the period from 2016 to 2020. Results: Of the 20,077 overall hospitalizations recorded, 4.0% were associated with the occurrence of TBI, of which, 75.3% were directly caused by traffic accidents involving motorcycles. The cases were concentrated in individuals of mixed race, male, aged between 18 and 29 years, with percentages of 92.5%, 86% and 39%, respectively. Conclusions: The occurrence of TBIs associated with automobile accidents is a problem that requires attention in the region. Moreover, there were several gaps in the completion of the medical records, which made it difficult to determine the association of the outcome, alcohol consumption and the use of PPE. However, considering all the information presented, assertive local public policies aimed at prevention can be implemented. And this can be the starting point for promoting changes aimed at mitigating traffic accidents and bed occupations due to preventable causes, impacting the quality of health care and economic factors (AU).

Introdução: No Brasil, os traumatismos cranioencefálicos (TCEs) representam cerca dois terços de todas as causas de óbitos e são frequentemente associados a acidentes de trânsito, causando sobrecarga dos serviços de média e alta complexidade. Objetivos: Descrever a ocorrência e o perfil clínico-epidemiológico de TCEs associados a acidentes de trânsito em um hospital regional no Sudeste do Estado do Pará. Materiais e Métodos: Trata-se de um estudo analítico de corte transversal. Baseou-se em dados provenientes do serviço de arquivos médicos e estatísticos de um hospital regional, através da análise de prontuários eletrônicos de pacientes diagnosticados com TCE decorrentes de acidentes de trânsito no período de 2016 a 2020. Resultados: Das 20.077 internações gerais re-gistradas, 4,0% foram associadas à ocorrência de TCE, das quais 75,3% foram diretamente causados por acidentes de trânsito envolvendo motocicletas. Os casos se concentraram em indivíduos pardos, do sexo masculino, com faixa etária entre 18 e 29 anos, com percentuais de 92,5%, 86% e 39%, respectivamente. Conclusões: A ocorrência de TCEs associados a acidentes automobilísticos é um problema que requer atenção na região. Além disso, verificou-se várias lacunas no preenchimento dos prontuários, o que dificultou a determinação da associação do desfecho, o consumo de álcool e a utilização dos EPIs. No entanto, considerando todas as informações apresentadas, políticas públicas assertivas locais que visem a prevenção podem ser implementadas. E esse pode ser o ponto de partida para promover mudanças que visem mitigação dos acidentes de trânsito e ocupações de leitos por causas evitáveis, impactando na qualidade da assistência em saúde e fatores econômicos (AU).

Local regulation of antral follicle development and ovulation in monovulatory species

The identification of mutations in the genes encoding bone morphogenetic protein 15 (BMP15) and growth and differentiation factor 9 (GDF9) associated with phenotypes of sterility or increased ovulation rate in sheep aroused interest in the study of the role of local factors in preantral and antral folliculogenesis in different species. An additive mutation in the BMP15 receptor, BMPR1b, which determines an increase in the ovulatory rate, has been introduced in several sheep breeds to increase the number of lambs born. Although these mutations indicate extremely relevant functions of these factors, the literature data on the regulation of the expression and function of these proteins and their receptors are very controversial, possibly due to differences in experimental models. The present review discusses the published data and preliminary results obtained by our group on the participation of local factors in the selection of the dominant follicle, ovulation, and follicular atresia in cattle, focusing on transforming growth factors beta and their receptors. The study of the expression pattern and the functionality of proteins produced by follicular cells and their receptors will allow increasing the knowledge about this local system, known to be involved in ovarian physiopathology and with the potential to promote contraception or increase the ovulation rate in mammals.(AU)

Does combining estradiol cypionate and GnRH for ovulation induction in recipient cows increase pregnancy rate after timed embryo transfer?

Estradiol cypionate (EC) or GnRH have been widely used for ovulation induction in timed embryo transfer (TET). EC administration increases the proportion of cows that show estrus, whereas GnRH promotes more synchronized ovulations. The aim of the present study was to evaluate the potential beneficial effects of combining EC and GnRH in TET. In experiment 1, no difference was observed on serum progesterone concentrations on Day 6 and 13 after GnRH treatment between GnRH and EC+GnRH groups. In experiment 2, pregnancy per embryo transfer (P/ET) did not differ (p = 0.69) between GnRH (62.8%) and EC+GnRH (58.7%) groups. In conclusion, combining EC and GnRH for ovulation induction does not increase progesterone secretion and pregnancy rate after TET in cattle.(AU)

Transfusão maciça no paciente traumatizado com contusão pulmonar: relato de caso

Introdução: A contusão pulmonar é uma condição frequentemente associada ao paciente politraumatizado, caracterizando-se como uma causa importante de lesão pulmonar aguda. Nos casos mais graves, pode desencadear síndrome do desconforto Respiratório Agudo (SDRA), associada a uma grande morbimortalidade. Ademais, é comum que nos casos de politrauma se necessite do disparo do protocolo de transfusão maciça. A transfusão de hemoderivados também está associada à geração de lesão pulmonar aguda, seja por mecanismos inflamatórios imunitários, como a lesão pulmonar aguda associada à transfusão e mecanismos atrelados à resposta inata, seja por reposição volêmica excessiva ou sepse. Pacientes que apresentam contusão pulmonar e necessitam de transfusão maciça apresentamuma combinação importante de elementos que podem induzir a lesão inflamatória dos pulmões, o que pode representar uma maior morbimortalidade para o paciente. Objetivo: Com o relato de caso em questão, fazer uma breve discussão sobre a necessidade de ativação de protocolo de transfusão maciça em pacientes com contusão pulmonar, além de relatar suas possíveis consequências e cuidados que a serem tomados. Relato do Caso: Descreve-se o caso de paciente com contusão pulmonar, evoluído com síndrome de angústia respiratória aguda, atendida em serviço de emergência do Hospital de Base de São José do Rio Preto, Brasil. Conclusão: Ao ponderar benefícios e malefícios a respeito da realização da transfusão sanguínea e transfusão maciça, há uma tendência a favor de seu uso rotineiro nos serviços de emergências sustentado por protocolos bem estabelecidos. Faz-se necessária, entretanto, a realização de novos estudos a fim de reduzir as complicações associadas à transfusão.

Implicações da COVID-19 para indivíduos com transtornos relacionado ao uso de substâncias psicoativas: revisão overview / Implications of COVID-19 for individuals with psychoactive substance use disorders: an overview / Implicaciones de COVID-19 para individuos con trastornos del consumo de sustancias psicoactivas: revisión general

Objetivo: explorar as implicações biopsicossociais da COVID-19 para indivíduos com transtornos relacionado ao uso de substâncias psicoativas, bem como as estratégias de atenção a essa população durante o surto de SARS-CoV-2. Método: estudo descritivo que incluiu diferentes desenhos de estudos em bases de dados virtuais para mostrar o crescimento do número de publicações na área da saúde mental com ênfase em álcool e outras drogas durante a pandemia de COVID-19. Para isso, foram selecionadas duas bases de dados (Biblioteca Cochrane, via Cochrane Database of Systematic Reviews e Medline, via PubMed). Resultados: pessoas com transtornos relacionados ao uso das substâncias psicoativas geralmente apresentam condições de saúde pré-existentes que podem indicar maior risco a infecção por COVID-19. Por outro lado, indivíduos que já faziam o uso de substâncias, podem se beneficiar do uso para alívio temporário da ansiedade causada por essa situação, aumentando os riscos de uso nocivo. Conclusão: questões biológicas, individuais (cognitivo comportamentais) e sociais afetam sobremaneira indivíduos com transtornos relacionados ao uso de substâncias psicoativas colocando-os em alto risco para o contágio e desenvolvimento da COVID-19.

Objective: to explore the biopsychosocial implications of COVID-19 for individuals with disorders related to the use of psychoactive substances, as well as the strategies to care for this population during the SARS-CoV-2 outbreak. Method: a descriptive study that included different study designs in virtual databases to show the growth in the number of publications in the area of mental health with an emphasis on alcohol and other drugs during the COVID19 pandemic. For this, two databases were selected (Cochrane Library, via Cochrane Database of Systematic Reviews and Medline, via PubMed). Results: people with disorders related to the psychoactive substances use generally have pre-existing health conditions that may indicate a higher risk of COVID-19 infection. On the other hand, individuals who already used substances can benefit from the use for temporary relief of anxiety caused by this situation, increasing the risks of harmful use. Conclusion: biological, individual (cognitive behavioral) and social issues greatly affect individuals with disorders related to the use of psychoactive substances, placing them at high risk for the contagion and development of COVID-19

The role of prostaglandin F2α on ovulation and LH release in cows / A função da prostaglandina F2α na ovulação e na liberação de LH em vacas

This study aimed to evaluate the role of prostaglandin F2α (PGF) on ovulation. In Experiment 1, cows were randomly allocated to two treatments to receive 150 µg of d-Cloprostenol (PGF Group, n = 12) or 2 mL of NaCl 0.9% (Control Group, n = 11) and CIDRs, were removed 4 days later. No cow ovulated in Control and PGF groups. In Experiment 2, cows were randomly separated into two experimental groups to receive 4 injections of 150 µg of d-Cloprostenol (n = 9) or 2 mL of NaCL 0.9% (n = 9). In this experiment, ovulation was not observed in any cows. In Experiment 3, ovariectomized cows receive three injections of 300µg of PGF analog (PGF Group, n = 5), 100µg of Lecirelin (GnRH Group, n = 5) or 2 mL of PBS (Control Group, n = 4). The LH concentration was higher (P <0.0001) in cows from the GnRH group than in the PGF and Control groups. In experiment 4, cows with preovulatory follicles (>11.5 mm) were treated with Saline (Control Group, n = 6); Lecirelin (GnRH Group, n = 7) or Cloprostenol Sodium (PGF Group, n = 6). There was a significant increase in the vascular area of follicles from 0 to 24 h in GnRH and PGF treatments. In conclusion, PGF was not able to induce ovulation in cows with high or low plasma progesterone concentration. Additionally, PGF alone was not able to induce LH release and follicle luteinization, but increased follicular vascularization.(AU)

O objetivo deste estudo foi avaliar o papel da prostaglandina F2α (PGF) na ovulação. No Experimento 1, as vacas foram alocadas aleatoriamente em dois tratamentos para receber 150 µg de d-Cloprostenol (Grupo PGF, n = 12) ou 2 mL de NaCl 0,9% (Grupo Controle, n = 11) e os CIDR, foram removidos 4 dias depois. Nenhuma vaca ovulou nos grupos Controle e PGF. No Experimento 2, as vacas foram separadas aleatoriamente em dois grupos experimentais para receber 4 injeções de 150 µg de d-Cloprostenol (n = 9) ou 2 mL de NaCL 0,9% (n = 9). Não foi observada ovulação em nenhum dos animais deste experimento. No Experimento 3, vacas ovariectomizadas receberam três injeções de 300µg de análogo de PGF (Grupo PGF, n = 5), 100µg de Lecirelina (Grupo GnRH, n = 5) ou 2 mL de PBS (Grupo Controle, n = 4). A concentração de LH foi maior (P <0,0001) nas vacas do grupo GnRH do que nos grupos PGF e Controle. No Experimento 4, vacas com folículos pré-ovulatórios (> 11,5 mm) foram tratadas com solução salina (Grupo Controle, n = 6), Lecirelina (Grupo GnRH, n = 7) ou Cloprostenol Sódico (Grupo PGF, n = 6). Houve um aumento significativo na área vascular dos folículos de 0 a 24h nos tratamentos com GnRH e PGF. Em conclusão, a PGF não foi capaz de induzir ovulação em vacas com alta ou baixa concentração plasmática de progesterona. Além disso, a PGF sozinha não foi capaz de induzir a liberação de LH e a luteinização do folículo, mas aumentou a vascularização folicular.(AU)
