Objetivo: compreender a percepção, das pessoas com diabetes mellitus tipo 1, quanto à qualidade do atendimento por programa de navegação de pacientes. Método: estudo descritivo com abordagem qualitativa, realizado em hospital universitário na região Sul do Brasil. Participaram 35 pessoas com diabetes mellitus tipo 1. Para coleta de dados, utilizaram-se entrevistas semiestruturadas por teleconsulta. Os dados foram submetidos à análise de conteúdo temática. Resultados: dos 35 (100%) participantes, 18 (51,4%) eram homens, com média de idade de 45 (±13) anos. Duas categorias temáticas e três principais temas sobre a qualidade do atendimento emergiram da análise dos dados: gerenciamento do diabetes (qualidade do atendimento em saúde prestado; conhecimento adquirido durante as consultas; melhoria nas práticas de autocuidado como resultado dos cuidados de saúde recebidos) e serviços de saúde remotos e presenciais (disponibilidade dos serviços de saúde durante a pandemia; desejo de acesso continuado aos serviços disponibilizados pelas enfermeiras; importância dos atendimentos recebidos). Conclusão: após análise das percepções dos participantes, foi possível compreender que a qualidade do atendimento oferecido pelo programa de navegação de pacientes é, em geral, positiva. Tanto que os usuários solicitaram continuidade deste modelo de assistência, vislumbrando uma oportunidade para além das dificuldades e das limitações impostas pela terapêutica.

Objective: to understand the perception of individuals with type 1 diabetes mellitus regarding the quality of care provided by a patient navigation program. Method: descriptive study with a qualitative approach, conducted at a university hospital in southern Brazil. A total of 35 individuals with type 1 diabetes mellitus participated. Data were collected through semi-structured interviews conducted via teleconsultation. The data were submitted to thematic content analysis. Results: of the 35 (100%) participants, 18 (51.4%) were men, with an average age of 45 (±13) years. Two thematic categories and three main topics related to care quality emerged from data analysis: diabetes management (quality of health care provided; knowledge gained during consultations; improvement in self-care practices as a result of received care) and remote and in-person health services (availability of health services during the pandemic; desire for continued access to services provided by nurses; importance of received care). Conclusion: after analyzing participants’ perceptions, it was understood that the quality of care offered by the patient navigation program is generally positive. Users requested the continuation of this care model, seeing it as an opportunity beyond the challenges and limitations imposed by treatment.

Objetivo: mapear as produções científicas nacionais e internacionais em saúde sobre a qualidade da assistência ambulatorial em enfermagem. Método: revisão de escopo orientada pela Colaboração Joanna Briggs Institute, realizada em 12 bases de dados e repositórios. Foram incluídos apenas artigos originais sobre a avaliação da qualidade da assistência ambulatorial em enfermagem. Não houve delimitação de tempo, metodologia ou idioma. Os dados foram mapeados e organizados por meio da descrição temática e estatística dos artigos. Esta revisão foi registrada na plataforma Open Science Framework. Resultados: foram encontrados 45 estudos publicados entre 1984 e 2021, originando 17 indicadores de qualidade da assistência ambulatorial de enfermagem, agrupados segundo a tríade de Donabedian: quatro de estrutura, sete de processo e seis de resultado. A área de cuidado predominante foi a oncologia. Dos estudos analisados, 55,3% tiveram foco nos pacientes. Os indicadores mais citados entre os estudos foram: educação permanente em saúde, organização do serviço, comunicação, coordenação do cuidado e processo de enfermagem. Conclusão: o pequeno número de estudos nesse campo, em comparação com outras áreas da enfermagem, demonstra a pouca exploração do tema nas realidades nacional e internacional. Além disso, a diversidade de indicadores encontrada aponta para a falta de uniformização desses dados.

Objective: to map national and international scientific literature on the quality of outpatient nursing care. Method: a scoping review guided by the Joanna Briggs Institute Collaboration, conducted across 12 databases and repositories. Only original articles evaluating the quality of outpatient nursing care were included. No restrictions were applied regarding time, methodology, or language. Data were mapped and organized through thematic and statistical descriptions of the articles. This review was registered on the Open Science Framework platform. Results: a total of 45 studies published between 1984 and 2021 were identified, resulting in 17 quality indicators for outpatient nursing care, grouped according to Donabedian’s triad: four for structure, seven for process, and six for outcomes. The predominant area of care was oncology. Among the analyzed studies, 55.3% focused on patients. The most frequently cited indicators were continuing health education, service organization, communication, care coordination, and the nursing process. Conclusion: the limited number of studies in this field, compared to other areas of nursing, highlights the underexploitation of the topic both nationally and internationally. Additionally, the diversity of identified indicators underscores the lack of standardization in these data.

ABSTRACT Objective: To evaluate the association between knowledge about the disease, adherence to self-care, and glycemic control in people diagnosed with type 1 diabetes mellitus. Subjects and methods: A cross-sectional study of patients aged over 18 years diagnosed with type 1 diabetes mellitus, treated at an outpatient clinic of a Brazilian university hospital. Participants with other types of diabetes, cognitive impairment, pregnancy, and outpatient discharge were excluded. Data were collected from January to March 2021 (by telephone call), with questions about the participants’ profile, diabetes knowledge questionnaire (DKN-A), and self-care inventory revised (SCI-R) translated into and adapted for Brazilian Portuguese. Data analysis involved chi-square associations, Mann-Whitney U tests, and Poisson regression. Results: Among 198 adult participants, the mean age was 42 ± 12 years, 53.5% were women, the mean glycated hemoglobin was 8.6 ± 1.6%, 140 (70.8%) had satisfactory knowledge about diabetes, 65 (32.8%) had adherence to self-care, and 46 (23.2%) had adequate glycemic control. We found an association between knowledge and adherence to self-care (p < 0.001). Knowledge was not associated with glycemic control (p = 0.705). Conclusion: Knowledge about diabetes was associated with greater adherence to self-care in people with type 1 diabetes mellitus, but it did not reflect in better glycemic control.

Objetivo: verificar a qualidade de vida e o comportamento alimentar de pacientes com obesidade durante a pandemia por COVID-19. Método: estudo transversal com 68 pacientes atendidos em ambulatório de cirurgia bariátrica em hospital universitário do sul do Brasil. A coleta de dados foi realizada por telefone, com perguntas sobre o perfil dos participantes e o distanciamento social; também foram utilizados questionários de qualidade de vida e de comportamento alimentar. Para a análise de dados, foram utilizados o modelo de regressão logística, a correlação de Spearman e os testes U de Mann-Whitney e t de Student, para amostras independentes. Resultados: a qualidade de vida geral foi de 57,03 pontos e o comportamento alimentar que apresentou maior pontuação foi a restrição cognitiva (61,11 pontos). Grande parte dos pacientes (72,1%) estava fazendo distanciamento social e 27,9% não haviam mudado a rotina. A chance de fazer isolamento foi 3,16 vezes maior para os pacientes que estavam casados. Existe uma correlação positiva entre os domínios do questionário de qualidade de vida e a restrição cognitiva das perguntas sobre o comportamento associado ao hábito alimentar. Conclusão: verificou-se que os participantes apresentaram tendência em ter uma melhor qualidade de vida conforme a restrição cognitiva aumentava.

Objective: to verify the quality of life and eating habits of patients with obesity during the COVID-19 pandemic. Method: cross-sectional study with 68 outpatients, candidates for bariatric surgery, at university hospital in the Southern Brazil. Data collection was carried out by telephone, with questions about the profile of the participants and social distancing; questionnaires on quality of life and eating habits were also used. The data analysis, the logistic regression model, Spearman correlation, Mann-Whitney U and Student t-tests were used for independent samples. Results: the general quality of life was 57.03 points and the eating habit with the highest score was cognitive restraint (61.11 points). Most patients (72.1%) were socially distancing themselves and 27.9% had not changed their routine. The chance of isolation was 3.16 times greater for patients who were married. There is a positive correlation between the domains of the Quality of Life questionnaire and cognitive restraint from the questionnaire about eating habits. Conclusion: we found that the participants tended to have a better quality of life as cognitive restraint increased.

RESUMO: O objetivo deste estudo foi avaliar dois aditivos alimentares, um a base de butirato de sódio encapsulado (Adimix® Precision) (AD) e outro a base de um fitogênico (Apex® 5) (AX), associados ou não a um antibiótico promotor de crescimento (tilosina), durante as fases de crescimento e terminação, sobre o desempenho, características da carcaça e status de saúde. Foram utilizados 300 suínos machos castrados e fêmeas distribuídos em seis tratamentos em um delineamento em blocos casualizados com dez repetições. Os tratamentos consistiram em um controle negativo (CN), controle positivo (CP) (tilosina), AD (butirato de sódio encapsulado), AX (fitogênico), CP+AD (tilosina+butirato de sódio encapsulado) e CP+AX (tilosina+fitogênico). Os dados de desempenho (peso vivo, consumo diário de ração, ganho de peso médio diário e conversão alimentar) e de carcaça (peso de carcaça, espessura de toucinho, profundidade do lombo e carne magra na carcaça) foram submetidos à ANOVA seguido por teste de Tukey, e os dados de condição de saúde (ocorrência de doenças, animais eutanasiados e mortos espontaneamente) foram analisados pelo teste de χ2. Os animais do grupo AD apresentaram maior ganho de peso diário (GPD) durante o período de avaliação e maior peso vivo aos 120, 140 e 164 dias de idade, além de maior peso de carcaça em comparação aos grupos CN e CP. O tratamento AX aumentou o GPD na fase crescimento II e o peso vivo aos 120 e 140 dias de idade em relação ao CN. O grupo CP+AX apresentou maior peso final em relação aos grupos CN e CP e maior peso de carcaça em relação ao CN. Não houve diferença entre os tratamentos para espessura de toucinho, porcentagem de carne magra na carcaça e ocorrência de doenças e óbitos. A inclusão de butirato de sódio encapsulado (tratamento AD) foi efetiva no aumento de GPD, peso final e peso de carcaça em comparação à suplementação com tilosina (tratamento CP), assim como a inclusão fitogênico (tratamento AX) melhorou a conversão alimentar em comparação ao grupo CP.

ABSTRACT: The aim of this study was to evaluate two feed additives, one based on encapsulated sodium butyrate (Adimix® Precision) (AD) and the other, a phytogenic (Apex® 5) (AX), associated or not with an antimicrobial growth promoter (tylosin) during the growth and finishing phases on performance, carcass characteristics and health conditions. A total of 300 barrows and females were distributed in six treatments in a randomized block design with ten replicates. The treatments consisted of a negative control (NC), positive control (PC) (tylosin), AD (encapsulated sodium butyrate), AX (phytogenic), PC+AD (tylosin+encapsulated sodium butyrate), and PC+AX (tylosin+phytogenic). The performance (live weight, daily feed intake, average daily gain and feed conversion) and carcass data (carcass weight, backfat thickness, loin depth, lean meat on the carcass) were submitted to ANOVA plus Tukey’s test, and the health conditions (occurrence of diseases, culling, and spontaneous deaths) were analyzed by χ2. Animals of the AD group had the highest average daily gain (ADG) over the evaluation period and the highest live weight at 120, 140, and 164 days of age, in addition to the highest carcass weight compared to NC and PC groups. The AX treatment increased the ADG in growth phase II and the live weight at 120 and 140 days of age in relation to the NC. The PC+AX group had a higher final live weight compared to the NC and PC groups and higher carcass weight in relation to the NC group. There was no difference among treatments for backfat thickness, percentage of lean meat in the carcass, or occurrence of diseases and deaths. The inclusion of encapsulated sodium butyrate (AD treatment) was effective in increasing ADG, final live weight, and carcass weight compared to supplementation with tylosin (PC treatment), as was the inclusion of a phytogenic (AX treatment) on FC compared to the PC.

ABSTRACT This study investigated the knowledge and perception of Brazilian pig producers in terms of environmental enrichment (EE) for pigs, the materials used, and the forms of presentation, identifying the single conditions that can improve their application on pig farms. A questionnaire was applied to 1340 farms – representing 7.4% of the farms and 12% of the sows in the country. The questions included descriptions of farms and respondents, their knowledge, judgments and level of interest in the use of EE, and frequency of use of the materials. Enrichment was used in 89.1% of farms, but half of the respondents admitted to using it without knowing what was involved. The producers presented an optimistic view (92.3%) about the application of this tool and were interested in receiving more knowledge and guidance on the subject (97.8%). The materials were used mainly to avoid fights (46.3%) and to prevent tail biting (23.3%); on the other hand, the increase in production costs (39.6%) and lack of knowledge about the subject (31.3%) were the main reasons for not using enrichment; concerns about increased management on farms were sporadic (7.1%). Metal chains were the main artifacts used, followed by plastic containers and pieces of wood; the same breeding farm used up to five types of materials. The fact that the respondents stated that they knew what EE was and that they had a good perspective on its use were significant conditions for the use of some kind of enrichment on the farms. Younger farm owners were more likely to use enrichment materials than more experienced ones. The results suggested that Brazilian pig producers use EE even with limited knowledge about the subject and that there is an argument to improve the use of this animal welfare strategy.

ABSTRACT This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an experimental unit and was followed from labor to weaning. The animals were assessed for their reproductive performance (labor duration, number of live births, mummified piglets, and stillbirths, and postpartum diseases). After weaning, the weaning-estrus interval and rate of return to estrus were assessed. A thermographic camera was used to identify hyperthermia of the mammary system and its relation with the onset of urinary tract infections. The prevalence of urinary tract infection in prepartum sows was 41.1%. Urinary tract infection does not impact labor duration, number of live births, mummified piglets, and stillbirths, number of sows culled, weaning-estrus interval, or return to estrus after insemination. However, it was considered a predisposing factor for the occurrence of postpartum vaginal discharge. There is no correlation between the occurrence of urinary tract infection and mammary system temperature in sows.

ABSTRACT The objective of this work was to study the behavior of swine females in the grower phase using different observation intervals (continuous, 5, and 10 min). A total of 42 swine were used, 14 of them for each treatment, which were identified with a marker stick. These animals were observed using the focal sampling method for 5 h. The treatments were the observation intervals: continuous, every 5 min, and every 10 min. Among the behaviors analyzed during the experiment, the different observation intervals did not affect the estimated time spent in the activities. Time observation intervals of 10 min or less adequately describe the duration of the main behavioral parameters of female pigs in this setting.

ABSTRACT The objective of this study was to evaluate the behavior of immunocastrated male pigs compared with females and castrated males during the period before and after full immunization. A total of 30 animals were divided into three treatments, with ten animals in each (females, barrows, and immunocastrated males). The experiment was divided into three periods: 70 to 80 days of age (period 1), 81 to 110 days of age (period 2), and 111 to 140 days of age (period 3). The behavior of animals during these stages was evaluated. Immunocastrated males showed a higher rate of aggressive and sexual behavior during period 2, which decreased after the second vaccine dose. Both barrows and immunocastrated males presented high locomotion in period 1, reducing the frequency of this activity in period 3. All analyzed animals had a higher level of activities such as drinking, playing, and sexual behavior in period 1 than in the other periods, decreasing during the experiment. The remaining behavioral responses did not differ between the studied categories. Immunocastrated males had higher proportions of undesirable behaviors (aggressive and sexual) related to the surgically castrated males and females, and these were reduced after the second vaccine dose. Immunocastration is effective in the reduction of behaviors such as agonistic and sexual at the same levels observed in females and surgically castrated males. However, immunocastrated pigs are more subject to these undesirable behaviors before full immunization.

El objetivo del estudio fue evaluar el efecto del número de partos y el suplemento de aceite de coco en lechones recien nacidos. Materiales y métodos. Se utilizaron 51 cerdas de diferentes partos y sus 642 lechones. Cada lechón se pesó y se identificó al nacer en orden secuencial. Fueron distribuidos aleatoriamente en dos grupos (CG = control y TG=tratamiento). Lechones TG tenían el primer acceso a una dosis de 3.0 ml de aceite de coco 12 horas después del nacimiento, y el segunda a las 36 h después de la primera. Los lechones fueron pesados a los 21 días. Con el fin de analizar el efecto de los suplementos de aceite de coco con relación al peso al nacer. Los lechones fueron agrupados de acuerdo con su peso (0.600 a 0.900 kg; 1.000 a 1.499 kg; 1.500 a 1.999 kg y 2.000 a 2.499 kg). Resultados. El número de partos afectó el peso y el número de lechones nacidos. Cerdas en cuarto, quinto y séptimo parto, tuvieron una camada mayor que las de segundo parto. Las cerdas de segundo y tercer parto tuvieron menor número de lechones y con peso mayor. No se encontró efecto del suplemento de aceite de coco en el desarrollo de los lechones recién nacidos. Conclusiones. Lo aceite de coco no es favorable para los lechones recién nacidos, tampoco para aquellos con el bajo peso al nacer, que normalmente presentan la energía corporal baja.

Objective. The study aimed to evaluate the effect of sows' of different parities and the supplement of coconut oil for piglets, on the development of litter. Materials and methods. A total of 51 sows of different parities and their 642 piglets were used in the trial. Each piglet was weighed and identified at birth in a sequential order. They were randomly distributed in two treatments (CG=control group and TG=test group). TG piglets had the first access to a dosage of 3.0 ml of coconut oil 12 hours after birth, and the second at 36 h after the first. Piglets were weighed at 21 days. In order to analyze the effect of the coconut oil supplement as a function of the weight at birth, piglets were grouped according to their weight (0.600 to 0.900 kg; 1.000 to 1.499kg; 1.500 to 1.999 kg; and 2.000 to 2.499 kg). Results. Sows parity affected the number and weight of born piglets. Sows in 4th, 5th and 7th parity had a larger litter than those from the 2nd parity. Sows from 2nd and 3rd parity had a lower number of piglets but heavier litter. No effect of the coconut oil supplement on neonatal piglets' performance was found. Conclusions. The coconut meal was neither beneficial to neonatal piglets nor to those with low weight at birth, which usually present low body energy.

Objetivo. Se realizó un estudio para evaluar el rendimiento y la concentración de urea en plasma (PUN) de los cerdos machos de medio potencial genético de carne magra en la canal sometidos a la inmunocastración. Materiales y métodos. Se utilizaron 45 cerdos de 70 días de edad Landrace x Large White. Los animales se distribuyeron en un diseño completamente al azar con tres tratamientos: machos castrados, hembras y machos inmunocastrados. Cada tratamiento consistió en tres repeticiones, con cinco animales por réplica. El período experimental fue de 70 días, divididos en las etapas de crecimiento (70 a 110 días de edad) y terminación (111 a 140 días de edad). Los cerdos fueron pesados cuatro veces: al inicio del experimento, en la primera dosis de vacuna de inmunocastración (80 días de edad), en la segunda dosis de la vacuna de inmunocastración (110 días de edad) y antes de el sacrificio (140 días de edad). Las muestras de sangre se recogieron en el mismo día en que se pesaron los animales. Resultados. Entre 80 y 110 días de edad, hubo un aumento en la cantidad de PUN, sólo para machos castrados y hembras. No hubo diferencias en la ganancia de peso entre los grupos en ninguno de los períodos estudiados. Machos inmunocastrados tuvieron menor consumo de alimento que las hembras y éstas mostraron un menor consumo que los machos castrados. En 110 días de edad, los animales inmunocastrados mostraron la conversión de alimento similar a las hembras y mejor que los machos castrados. Sin embargo, después de la segunda dosis de la vacuna, la conversión alimenticia fue similar entre los grupos. Conclusiones. Los beneficios de inmunocastración son prominentes en animales con bajo a médio potencial genético.

Objective. A study was carried out to evaluate the performance and the plasma urea nitrogen (PUN) of male pigs of medium genetic potential for lean meat deposition in carcass, which underwent immunocastration. Materials and methods. Forty-five seventy-days old Large White x Landrace crossbred were used. The pigs were distributed in a randomized design in three treatments: castrated males, females and immunocastrated males. Each treatment group was replicated three times with five pigs per replicate. The trial period was of 70 days, divided into phases of growing (70 to 110 days old) and finishing (111 to 140 days old). The pigs were weighed four times: at the beginning of the trial, at the first immunocastration vaccine dose (80 days old), at the second immunocastration vaccine dose (110 days old) and just before slaughter (140 days old). Blood samples were taken on the same day that the animals were weighed. Results. Between 80 and 110 days old, there was an increase in PUN value, only for castrated males and females. No differences were found in weight gain between the studied groups within the periods. Immunocastrated males had lower feed intake than females and these had a lower feed intake than castrated males. To 110 days old, immunocastrated animals showed feed conversion ratio similar to females and better than castrated males. However, after the second dose of the vaccine, feed conversion was similar between groups. Conclusions. The benefits of immunocastration are prominent in animals with low to medium genetic potential.

O estudo foi conduzido com o objetivo de avaliar o desenvolvimento microbiológico em carne suína PSE em comparação à carne normal e o efeito da época do ano sobre a velocidade de proliferação dos mesmos. Amostras do músculo Longissimus dorsi de carcaças classificadas ao abate como PSE (pH45<5,8) e normais (pH45>5,8), foram coletadas após 24 horas de refrigeração, no momento da desossa, em um abatedouro comercial, com serviço de inspeção federal, situado na região da Grande Dourados (MS). As amostras (12 normais e 12 PSE) foram coletadas em duas épocas distintas do ano (outono e inverno) para as análises de coliformes totais, coliformes a 45ºC, mesófilos, psicotróficos, pseudômonas, bolores e leveduras aos 0, 5, 10 e 15 dias de armazenamento por refrigeração. O crescimento microbiano comportou-se de maneira semelhante entre os dois tipos de carne ao longo do período de armazenamento, exceto para a contagem de microorganismos aeróbios mesófilos totais, cujo desenvolvimento foi superior em carnes PSE até o 5º dia de armazenamento, igualando-se entre os dois tipos de carne posteriormente. Houve efeito da época do ano sobre a contagem de coliformes totais e a 45ºC, sendo sua velocidade de proliferação superior em carnes provenientes dos animais abatidos na época mais quente (outono).

The study was conducted to evaluate the microbiological development in PSE pork compared with normal meat and the effect of season of the year on the rate of proliferation of the same. Longissimus dorsi muscle samples from carcasses classified as PSE slaughter (pH45 <5.8) and normal (pH45 > 5.8) were collected after 24 hours of refrigeration, at the time of deboning, in a commercial slaughterhouse, with service federal inspection, located in the Grande Dourados region (MS). The samples (12 normal and 12 PSE) were collected at two different times of the year (fall and winter) for analysis of total and 45ºC coliforms, mesophylls, psychotropic, pseudomonas, yeasts and molds at 0, 5, 10 and 15 days of storage under refrigeration. Microbial growth behaved similarly between the two types of meat throughout the storage period, except for the count of mesophilic aerobic microorganisms, whose development was superior in PSE meat until the 5th day storage, matching between both types of meat later. Was no effect of season on the count of total coliforms and 45ºC, and their proliferation rate higher in meat from the slaughtered animals the warmer season (autumn).
