RESUMO

Aim: to evaluate the occurrence of maxillofacial infection cases, which were treated at local hospital, identifying the main risk factors that determine the need for hospitalization of patients and the factors associated with staying length. Methods: A retrospective review of 191 records of patients with maxillofacial infection of odontogenic origin was performed, statistically evaluated by frequency and percentage of involvement, p values (based on the chi-square test) and odds ratio with a 95% confidence interval. A p-value <0.05 was considered statistically significant. Results: Among all the 191 patients, 31 had some harmful habits, such as smokers (13%) and alcoholics (1%). In addition, 39 patients reported some general health problem, such as systemic arterial hypertension (8.3%), depression (6.8%), diabetes (3.6%) and some immunosuppression (1.57%). Involvement of infection in deep facial spaces was present, with 119 patients presenting a deeper infection (62.3%) and 72 patients a superficial infection (37.7%). The most prevalent clinical signs and symptoms in the initial evaluation were pain (91.1%) and edema (90.1%), followed by erythema/hyperemia (44.5%), trismus (37.7%), abscess (30.9%), cellulitis (27.7%), f istula (16.8%), fever (16.8%), dysphagia (11%), dehydration (9.9%), odynophagia (7.9% ) and dyspnea (3.7%). Pulp necrosis was considered a risk factor for treatment in a hospital environment (0.032) and root canal treatment decreases the risk of hospitalization (p=0.002). Considering the evaluated patients, 146 (76.4%) were admitted and 45 (37.7%) were not admitted for hospitalization after initial clinical evaluation. Conclusion: there is a high occurrence of maxillofacial infection cases of dental origin, considering that involvement of infection in deeper facial spaces, as well as presence of pain, edema, erythema/hyperemia, trismus, abscess, cellulitis and pulp necrosis, represent the main risk factors for hospitalization and staying length

RESUMO

Resumo Hemocromatose hereditária (HH) é a doença genética mais comum em descendentes de europeus e sua epidemiologia em nosso país é incerta. Considerando o cenário das políticas públicas em HH no mundo contemporâneo, este artigo propõe uma reflexão sobre o tema, com objetivo de fazer uma revisão bibliográfica narrativa sobre a abordagem adotada para essa doença em países desenvolvidos e a nível nacional. Além disso, discute sobre o custo-benefício da incorporação do índice de saturação da transferrina (ST) e ferritina sérica (FS) no nosso sistema de saúde, com a finalidade de identificar a HH antes que surjam suas complicações, bem como seu rastreio em campanhas nacionais de prevenção. O valor gasto para o screening da HH com dosagem de ST e FS pelo Sistema Único de Saúde (SUS) é muito menor do que os custos gerados quando o dano por excesso de ferro já está estabelecido. Nos casos suspeitos de HH, deveria ser viabilizada pelo SUS a pesquisa da mutação genética para o gene HFE, que atualmente só está disponível de forma privada. Com essas medidas, modifica-se a história natural da doença, reduzindo a morbimortalidade dos portadores e custos ao sistema público de saúde.

Abstract Hereditary hemochromatosis (HH) is the most common genetic disease among European descendants and its epidemiology in Brazil is unclear. Considering the contemporary public policy scenario aimed at HH, this narrative bibliographic review reflects on the approach adopted for this disease at the national level in developed countries. It also discusses the cost-effectiveness of incorporating transferrin saturation (TS) and serum ferritin (SF) indexes in the Brazilian healthcare system for early HH identification, as well as its screening in national prevention campaigns. The amount spent on ST- and FS-based HH screening by the Brazilian National Health System (SUS) is much lower than the costs generated by the already established iron overload. In suspected cases, genetic mutation research of the HFE gene, which is currently only performed privately, should be made available by the SUS. These measures can modify the natural history, reducing HH morbidity and mortality and its costs to the public health system.

RESUMO

The present study described the chemical composition and somatic cell score (SCS) of samples of refrigerated raw milk collected from commercial farms in the state of Rio Grande do Sul in order to better understand the behavior of constituents present in non-fatty solids (NFS) in milk according to the season of the year. Means were used to describe statistical data. To estimate the probability of NFS levels meeting IN 76 (BRAZIL, 2018), binary logistic regression was used. It was reported that 18.2% (233.817) of analytical results showed NFS below 8.4%, representing the minimum required by IN 76. The highest average NFS level observed in the five-year period was registered in the micro-region of Passo Fundo (8.70%) in winter. The microregion with the lowest results was Porto Alegre (8.53%); however, it still demonstrated levels within the limits established by IN 76. The study indicates that milk constituents show differences between seasons. In autumn and winter, the constituents remained equal to or higher than those required by current legislation, while spring and summer were the periods with the lowest NFS values. The SCS was also influenced by the seasons, with the highest rates in spring, summer, and autumn.

O presente estudo teve como objetivo descrever os resultados de composição química e escore de células somáticas (ECS) de amostras de leite cru refrigerado coletado em fazendas comerciais no estado do Rio Grande do Sul, para melhor entendimento do comportamento dos constituintes presentes nos sólidos não gordurosos (SNG) no leite de acordo com as estações do ano. As médias foram estudadas para descrever as estatísticas dos dados. Para estimar a probabilidade de os teores de SNG atenderem à IN 76 de 2018, foi utilizada a regressão logística binária. Foi constatado que 18,2% (233.817) dos resultados analíticos apresentaram SNG abaixo de 8,4%, que representa o mínimo exigido pela IN 76 (BRASIL, 2018). A maior média de SNG observada no período de cinco anos foi registrada na microrregião de Passo Fundo (8,70%), no inverno. A microrregião com menores resultados foi a de Porto Alegre (8,53%), no entanto com teores dentro do estabelecido pela IN 76/2018. O estudo demonstrou que os constituintes do leite apresentaram diferenças entre as estações do ano. O outono e inverno foram os períodos em que os constituintes se mantiveram iguais ou superiores aos exigidos pela legislação vigente, enquanto que a primavera e o verão foram os períodos com os menores valores de SNG. O ECS também foi influenciado pelas estações do ano. Na primavera, verão e outono ocorreram os maiores índices.

RESUMO

The objective of this study was to evaluate and compare two chemical preservatives in terms of their sample preservation capabilities, considering the individual bacterial count (IBC) and time and temperature variables. Samples were collected in expansion tanks in three commercial dairy farms located in the northwest of Rio Grande do Sul, characterized as G1: low IBC values, G2: average IBC values, and G3: high IBC values. The tanks were stored at three different temperatures (4, 10, and 25 °C) for 14 d. Samples supplemented with the preservative Azilat in G1 (lower IBC group) exhibited the best results at a temperature of 4 °C, whereas for G2 and G3, the results showed no statistically significant difference between temperatures 4 and 10 °C. The temperature 25 °C exhibited the worst results. For samples preserved with Azidiol, regardless of the studied group (G1, G2, and G3), the temperatures of 4 and 10 °C did not present a significant difference regarding the preservation of the samples, with the temperature of 25 °C exhibiting the worst results. Azilat was effective in keeping the samples conserved when they presented low IBC, being able to fluctuate with the increase in IBC and temperature variation. Azidiol was effective regardless of the initial IBC level.

RESUMO

O absenteísmo e o bem-estar no trabalho (isto é, a síndrome de burnout e o work engagement) são duas realidades distintas que têm caracterizado a categoria dos profissionais da enfermagem e as organizações de saúde em nível mundial. Este artigo tem como objetivo analisar a relação entre o bem-estar no trabalho e o absenteísmo nos profissionais de enfermagem que atuam em ambiente hospitalar. O estudo de corte transversal foi realizado com profissionais da categoria de enfermagem, que trabalham em três hospitais no município de Passo Fundo (RS), Brasil. Trata-se de uma pesquisa de abordagem quantitativa que contou com a participação de 201 profissionais da enfermagem, absenteístas e não absenteístas. O bem-estar foi mensurado por meio de questionário derivado do Maslach Burnout Inventory que mediu duas dimensões core do burnout (cinismo e exaustão) e o work engagement foi medido por meio da Utrecht Work Engagement Scale. Os resultados, nesta amostra, apontaram um alto nível de engagement e um baixo nível de burnout, não sendo registradas diferenças significativas entre os dois grupos de profissionais de enfermagem, absenteístas e não absenteístas.

RESUMO

Introduction: Streptococcus gallolyticus belongs to theStreptococcus bovis complex, and it is a common bacterium colonizing the gastrointestinal tract. Its presence in the blood may suggest an underlying pathology such as a colonic neoplasm. We report herein a case of S. bovis bacteremia in an apheresis platelet donor, review similar cases in the literature, and suggest a flowchart for the management of similar cases in other blood donation centers. Case Presentation: A 61-year-old subject presented to a Hemotherapy Service to make an apheresis platelet donation. On quality control testing, S. gallolyticus was identified in hemoculture, and the donor was called back for follow-up. At first, a new hemoculture was requested, and the patient was referred to the outpatient department of infectious diseases to further investigate pathologies associated with S. gallolyticus. A subsequent colonoscopy investigation evidenced a polypoid structure in the ascending colon. Pathology reported the resected specimen as a low-grade tubular adenoma. Conclusion: Isolation of S. bovis in blood products requires further investigation and should be managed with precision by Hemotherapy Services. A standard protocol for the management of asymptomatic patients with S. bovis positive hemoculture, with the requests of a new blood culture, a colonoscopy, and an echocardiogram is crucial, as it may ensure early diagnosis and reduce morbidity and mortality.

RESUMO

BACKGROUND: Older people often do not meet the recommended levels of exercise required to reduce functional decline. Social interaction is mentioned by this cohort as a reason for joining group-based exercises, which does not occur when exercising alone. This perspective shows that exergames can be used as motivational resources. However, most available exergames are generic, obtained from commercial sources, and usually not specifically designed or adapted for older people. OBJECTIVE: In this study, we aim to co-design and develop a new exergame alongside older participants to (1) tailor the game mechanics and optimize participants' adherence to and enjoyment of exercise; (2) test the participants' functional capacity, motivation, and adherence to the exergaming program; and (3) compare these scores between those who played alone and those who played with peers. METHODS: We conducted a co-design process to develop a new exergame adapted to older people. For user testing, 23 participants were divided into 2 groups to play individually (alone group) or to compete in pairs (with peers group). They played the game twice a week, resulting in 21 exergaming sessions. We assessed the participants' General Physical Fitness Index (GPFI) before and after the user testing. We also administered questionnaires about the gaming experience and exercise adherence with its motivators and barriers. RESULTS: We introduced a new bowling exergame for Xbox with a Kinect motion sensor that can be played in single or multiplayer mode. For the GPFI measurements, the sample was homogeneous in the pretest (with peers group: mean 40.5 [SD 9.6], alone group: mean 33.9 [SD 7.8]; P=.11). After the exergame testing sessions, both groups had significant gains (with peers group: mean 57.5 [SD 8.7], P=.005; alone group: mean 44.7 [SD 10.6]; P=.02). Comparing the posttest between groups, it was found that the group in which participants played with peers had better outcomes than the group in which participants played alone (P=.02). Regarding the gaming experience and exercise adherence, both groups recognized the benefits and expressed enthusiasm toward the exergame. CONCLUSIONS: The findings suggest that the developed exergame helps in improving the functional capacity and adherence to physical exercise among older people, with even better results for those who played with peers. In addition to leading to more appropriate products, a co-design approach may positively influence the motivation and adherence of participants.

RESUMO

Introdução: O carcinoma epidermoide é uma patologia que corresponde a 90% dos tumores malignos da cavidade oral. Objetivo: Avaliar o perfil epidemiológico, o tratamento e a sobrevida dos pacientes diagnosticados com carcinoma epidermoide oral em um hospital referência na Região Norte do Estado do Rio Grande do Sul, Brasil. Método: Estudo observacional retrospectivo, com análise dos prontuários dos pacientes com diagnóstico dessa patologia, no período de 1993 a 2008, no banco de dados desse hospital. Os dados foram analisados pelo programa estatístico SPSS versão 18 utilizando testes paramétricos e não paramétricos. Resultados: Foram coletados e analisados dados de 303 prontuários que revelaram que 88,4% eram homens, leucodermas, com maior incidência na faixa etária entre 51 e 60 anos. A associação de álcool e tabaco foi observada em 84,7% dos pacientes. O local mais afetado foi a língua (45,5%) e a maioria dos casos apresentou estádios tardios III e IV com uma sobrevida de 17,83 meses. Embora o tratamento cirúrgico tenha sido o mais realizado (55,9%) e apresentado a maior sobrevida, não foi observada significância estatística deste com relação aos demais tratamentos (p=0,185). Conclusão: O perfil epidemiológico dos pacientes é muito semelhante aos registros de vários países. Neste caso, o diagnóstico tardio diminuiu significativamente a expectativa de vida dos pacientes (2,5x), e o tratamento executado bem como o local inicial da lesão não tiveram influência significativa na sobrevida

Introduction: The squamous cell carcinoma is a pathology accounting for 90% of all the malignant tumors found in the oral cavity. Objective: This study aimed to assess the epidemiological profile, treatment, and survival of patients diagnosed with oral squamous cell carcinoma at a reference hospital of the northern region of the state of Rio Grande do Sul, Brazil. Method: Retrospective observational study with analysis of the patients' charts diagnosed with this condition from 1993 to 2008 at this hospital database. The data collected were analyzed using the statistical program SPSS version 18 using parametric and non-parametric tests. Results: From the 303 charts analyzed, 88.4% were men, Caucasian, leukoderma, with higher incidence in the age range between 51 to 60 years old. The association of alcohol with tobacco was detected in 84.7% of the patients. The most affected site was the tongue (45.5%), and most of the cases were diagnosed in late stage III and IV, with survival of 17.83 months. Although surgical treatment has been performed more frequently (55.9%) and presented higher survival rates, its statistical significance in comparison with other treatments was not demonstrated (p=0.185). Conclusion: The epidemiological profile of patients is very similar to the charts of several countries. In the present case, the late diagnosis significantly decreased life expectancy of patients (2.5-fold), and that the treatment, and the initial site of the lesion had no significant influence on survival
