Extrahepatic cholestasis associated with paracoccidioidomycosis: Challenges in the differential diagnosis of biliopancreatic neoplasia.

BACKGROUND: Paracoccidioidomycosis (PCM) may involve the hepatic pedicle and peripancreatic lymph nodes, cause damage to the bile duct and manifest, exceptionally, in combination with extrahepatic cholestasis (EHC), making investigation and treatment challenging. AIM: To investigate the management of patients with visceral PCM admitted with EHC. METHODS: All patients diagnosed with PCM treated in a public, tertiary teaching hospital between 1982 and 2020 were retrospectively evaluated. Those also identified with EHC were allocated to two groups according to the treatment approach for the purpose of comparing clinical, laboratory, and imaging findings, resources used for etiological diagnosis, treatment results, and prognosis. Statistical analyses were performed using the linear mixed-effects model (random and fixed effects), which was adjusted using the PROC MIXED procedure of the SAS® 9.0 software, and Fisher's exact test. RESULTS: Of 1645 patients diagnosed with PCM, 40 (2.4%) had EHC. Of these, 20 (50.0%) lived in the rural area and 29 (72.5%) were men, with a mean age of 27.1 years (3-65 years). Jaundice as first symptom and weight loss of at least 10 kg were observed in 16 patients (40.0%), and a mass in the head of the pancreas was observed in 8 (20.0%). The etiological diagnosis was made by tissue collection during surgery in 4 cases (10.0%) and by endoscopic methods in 3 cases (7.5%). Twenty-seven patients (67.5%) received drug treatment alone (Group 1), whereas 13 (32.5%) underwent endoscopic and/or surgical procedures in combination with drug treatment (Group 2). EHC was significantly reduced in both groups (40.7% in Group 1, with a mean time of 3 months; and 38.4% in Group 2, with a mean time of 7.5 months), with no statistically significant difference between them. EHC recurrence rates, associated mainly with treatment nonadherence, were similar in both groups: 37% in Group 1 and 15.4% in Group 2. The mortality rate was 18.5% in Group 1 and 23% in Group 2, with survival estimates of 71.3% and 72.5%, respectively, with no statistically significant difference. CONCLUSION: Although PCM-related EHC is rare, it needs to be included in the differential diagnosis of malignancies, as timely treatment can prevent hepatic and extrahepatic sequelae.

Phase Angle but Not Psoas Muscle Predicts Nutritional Risk and Prognosis in Males with Hepatocellular Carcinoma.

Despite those with hepatocellular carcinoma (HCC) being at increased risk of malnutrition, there is a notable absence of practical approaches for nutritional assessment in clinical practice. We investigated the usefulness of phase angle (PhA) and Total Psoas Area Index (TPAI) for indicating nutritional risk and HCC prognosis. Weight, height, body mass index (BMI), adductor pollicis muscle thickness (APMT), and handgrip strength (HGS) were assessed. The Nutritional Risk Index (NRI) was calculated. Body composition was assessed using bioimpedance spectroscopy and magnetic resonance imaging. The Child-Turcotte-Pugh (CTP) score and Barcelona-Clinic Liver Cancer (BCLC) classification determined the prognosis. Fifty-one males with HCC were enrolled (CTP C = 11.8%). PhA showed a moderate positive correlation with APMT (r = 0.450; p < 0.001) and HGS (r = 0.418; p = 0.002) and a weak positive correlation with TPAI (r = 0.332; p = 0.021). PhA had a strong positive correlation with NRI (r = 0.614; p < 0.001). Mean PhA values were significantly different according to disease severity (CTP C p = 0.001, and BCLC D p = 0.053). TPAI had no significant correlation with HGS, CTP, or BCLC. PhA was a superior approach for predicting nutritional risk and prognosis in HCC than TPAI. Lower PhA is associated with disease progression, lower muscle mass and function, greater severity of nutritional risk, and increased mortality in HCC.

The Frequency of Anatomical Variants of the Bile Ducts: A Review Based on a Single Classification as Support for Cholangiographic Examinations.

Complications arising from hepatobiliary surgery can have adverse effects on both the quality of life and the survival of patients. Magnetic resonance cholangiography (MRC) techniques are highly effective at revealing anatomical variants of the bile ducts and thus play a vital role in minimizing the occurrence of complications. The aims of this review are threefold: to ascertain the classifications utilized for categorizing anatomical variants of the bile ducts, to present the reported results on the prevalence of these anatomical variants, and to explore the diagnostic modalities employed to visualize these anatomical variants and associated complications during surgical procedures. A review of the literature was carried out using the Cochrane Library database and the PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), and Google Scholar platforms. We conducted a comprehensive review of relevant studies to categorize the different anatomical variants according to the Huang classification. According to the Huang classification, our study showed type A1, 60.44%; type A2, 11.76%; type A3, 11.73%; type A4, 5.47%; type A5, 0.26%; and type B, which was identified in insignificant numbers (0.16%) or does not appear; additionally, variants that do not fit into the Huang classification have also been identified (10.18%). The Huang classification serves as an invaluable presurgical guide, aiding in the strategic planning of biliary interventions and effectively reducing the risk of iatrogenic complications, morbidity, mortality, and postoperative length of stay. MRC is still considered the noninvasive gold standard method for evaluating the bile ducts and their anatomical variations.

The Safety and Cost Analysis of Outpatient Laparoendoscopy in the Treatment of Cholecystocholedocholithiasis: A Retrospective Study.

INTRODUCTION: The advantages of single-stage treatment of cholecystocholedocholithiasis are well established, but the conditions for carrying out treatment on an outpatient basis require a review of concepts and practices of medical corporations. OBJECTIVE: To evaluate the practice of treating cholecystocholedocholithiasis by laparoendoscopy on an outpatient basis with cost analysis. METHOD: A retrospective study was conducted on patients with cholecystocholedocholithiasis treated by combined laparoscopic cholecystectomy and endoscopic choledocholithotomy from January 2015 to January 2019. After collecting data from physical and digital medical records, the patients were divided into two groups-AR (n = 42)-ambulatory regimen and HR (n = 28)-hospitalization regimen-which were compared in terms of demographic, clinical and treatment variables and their results, as well as in terms of costs. RESULTS: The mean age of the AR group was lower than that of the HR group and the physical status of the AR patients was better when assessed according to the American Society of Anesthesiologists (ASA) (p = 0.01). There was no difference between groups regarding the risk of choledocholithiasis (p = 0.99). For the AR group, the length of stay was shorter: 11.29 h × 65.21 h (p = 0.02), as was the incidence of postoperative complications assessed by applying the Clavien-Dindo classification: 3 (7.1%) × 11 (39.2%) (p < 0.01). The total mean costs were higher for the HR group (USD 2489.93) than the AR group (USD 1650.98) (p = 0.02). CONCLUSION: Outpatient treatment of cholecystocholedocholithiasis by laparoendoscopy is safe and viable for most cases, has a lower cost and can support the reorientation of training and practice of hepatobiliary surgeons.

Global DNA methylation patterns in Alcohol Use Disorder.

Alcohol Use Disorder (AUD) is a highly prevalent condition worldwide that produces a wide range of pathophysiological consequences, with a critical impact on health and social issues. Alcohol influences gene expression through epigenetic changes mainly through DNA methylation. In this sense, levels of 5-methylcytosine (5-mC), namely Global DNA methylation (GMe), which can be influenced by environmental and hormonal effects, represent a putative biological mechanism underlying alcohol effects. Our aim was to investigate the influence of AUD diagnosis and alcohol patterns (i.e., years of addiction, use in the last 30 days, and alcohol severity) on GMe levels. The sample consisted of 256 men diagnosed with AUD and 361 men without AUD. DNA samples from peripheral blood were used to assess GMe levels, measured through the levels of 5-mC using high-performance liquid chromatography. Results from multiple linear regression analysis indicated that the presence of AUD was associated with lower GMe levels (beta=-0.155, p=0.011). Other alcohol-related outcomes were not associated with DNA methylation. Our findings are consistent with the hypothesis that the impact of chronic and heavy alcohol use in GMe could be a potential mechanism mediating the multiple organ damages related to AUD.

Photoanthropometric craniofacial parameters in individuals with osteogenesis imperfecta / Parámetros craneofaciales fotoantropométricos en personas con osteogénesis imperfecta

Background: This study aimed to evaluate facial photoanthropometric parameters in patients with OI.Material and Methods: We selected 20 Brazilian patients diagnosed with OI treated at the Extension Service forMinors in Need of Specialized Treatment of the Dentistry Course at the Federal University of Ceará (Fortaleza,Brazil), of both sexes, without age restriction, and able to understand and sign the informed consent form (ICF).As a control group, 38 non-syndromic Brazilian individuals, categorized as ASA I, able to understand and sign theICF, matched by sex, age, and Legan and Burstone facial profile were selected. The exclusion criteria were: previ-ous orthodontic treatment, craniofacial trauma and/or surgery, and the presence of any other systemic diseases.Photoanthropometric analysis of the 18 facial parameters proposed by Stengel-Rutkowski et al. (1984), previouslyestablished in the literature for craniofacial syndromes, were conducted. A single examiner digitally performedall effective and angular measurements with the CorelDRAWX7® software.Results: Horizontally shortened ears (p<0.001) but larger in height in relation to the face (p=0.012) were shownto be alterations belonging to individuals with OI.Conclusions: OI patients present distinct photoanthropometric parameters inherent in this condition.(AU)

Factors associated with the lifestyle of state basic education teachers of state during the pandemic.

OBJECTIVE: To analyze the prevalence and factors associated with the lifestyle profile of public basic education teachers in Minas Gerais during the COVID-19 pandemic. METHOD: Epidemiological websurvey carried out with public basic education teachers in Minas Gerais. Data collection took place from August to September2020 via digital form. Anthropometric, sociodemographic, work, and lifestyle characteristics were evaluated. Poisson Regression was used. RESULTS: 15,641 teachers participated and 31.1% had inadequate health habits. There was a higher prevalence among men (PR=1.38; 95%CI:1.31;1.45), older age (PR=1.20; 95%CI: 1.07;1.34), greater weekly workload (RP=1.10; 95%CI:1.03;1.17) and those dissatisfied with work (RP=1.21; 95%CI:1.15;1.27). As a protective factor, professors with longer teaching experience (RP=0.92; 95%CI:0.87;0.98) and those hired or appointed (PR=0.89; 95%CI:0.85) ;0.94). CONCLUSION: Lifestyle inadequacy was found among older male teachers, with longer working hours and job dissatisfaction.

In vitro evaluation of human intravenous immunoglobulin in combination with antimicrobials and human serum against multidrug-resistant isolates of Acinetobacter baumannii.

The high incidence of multidrug-resistant (MDR) Acinetobacter baumannii has been a challenge for health worldwide, due to the reduction of therapeutic options, making the use of antimicrobial combinations necessary for the treatment, such as meropenem, amikacin, and colistin. Antibodies against bacterial species, mainly immunoglobulins G (IgG), are produced for acting as effector mechanisms (neutralization, opsonization, phagocytosis, and complement system activation). Some studies have demonstrated promising results of IgG in combination with antimicrobial preparations against bacterial infections, in which the direct action of IgG has restored the immune system balance. Serious problem caused by the increase of MDR A. baumannii isolates results in a constant search for therapeutic alternatives to defeat these infections. However, this study aims to verify in vitro the phagocytosis rate of the A. baumannii-infected human monocytes, as well as to analyze possible morphological changes induced by intravenous immunoglobulin G (IVIG) with human serum in association with antimicrobials. The phagocytosis rate and bacterial cell binding capacity of IVIG were determined for two A. baumannii isolates submitted to 4 mg/mL of human IVIG alone and in combination with different sub-minimum inhibitory concentrations (sub-MICs) of meropenem, amikacin, and colistin and processed for indirect immunofluorescence. Subsequently, these isolates were resubmitted and coupled with human serum and processed for scanning electron microscopy. There was no statistical difference for phagocytosis rates in the isolates tested. Bacterial isolates showed alterations in cell morphology when exposed to IVIG/human serum alone and in combination with antimicrobials such as alteration in shape, wrinkling, membrane depression, and especially cell rupture with extravasation of cytoplasmic material. The isolates visually differed in the IVIG binding to the bacterial cell, with higher fluorescence intensity, which corresponds to the highest IVIG binding, in the isolate more sensitive to meropenem, amikacin, and colistin. No differences between treatments were observed in the IVIG binding to the bacterial cell. The combined action of IVIG with meropenem, amikacin, and colistin against A. baumannii MDR isolates induced several bacterial cell damages. And when associated with human serum, a massive destruction of cells can be observed. These results may suggest the analysis of the use of IgG preparations for the treatment of A. baumannii MDR infections.

Reconstrução da ponta nasal: relatos de casos e revisão histórica / Nasal tip reconstruction: case reports and historical review

As amputações traumáticas da ponta nasal são lesões desfigurantes, que determinam importante rejeição social, impondo ao paciente um sofrimento adicional, além daqueles já causados pela ferida e suas limitações funcionais decorrentes do traumatismo. Tais defeitos representam um desafio para os cirurgiões plásticos, e existem diversas técnicas que poderão ser adotadas para tratar este mesmo tipo de defeito. Neste trabalho são mostrados inicialmente três casos de amputação traumática exclusivamente da ponta nasal com seus respectivos tratamentos, para em seguida apresentar uma revisão histórica e discussão das diversas técnicas utilizadas para reconstrução da ponta nasal, avaliando comparativamente e enfatizando a evolução técnica no armamentário da cirurgia plástica.

Traumatic amputations of the nasal tip are disfiguring injuries, which determine important social rejection, imposing additional suffering on the patient and those already caused by the wound and its functional limitations resulting from the trauma. Such defects represent a challenge for plastic surgeons, and several techniques can be adopted to treat this type of defect. This work shows three cases of traumatic amputation exclusively of the nasal tip with their respective treatments. They present a historical review and discussion of the different techniques used for nasal tip reconstruction, comparatively evaluating and emphasizing the technical evolution in plastic surgery armament.

In vitro inhibition and eradication of multidrug-resistant Acinetobacter baumannii biofilms by riparin III and colistin combination.

Acinetobacter baumannii, a prominent emerging pathogen, is responsible for persistent and recurrent healthcare-associated infections (HAIs). Its bacterial resistance and virulence factors, such as biofilm formation, contribute to its survival in hospital environments. Combination therapy has proven to be an effective approach for controlling these infections; however, antimicrobial resistance and compound toxicity can hinder antimicrobial efficacy. Numerous in vitro studies have demonstrated the synergistic effect of antimicrobials and natural products against multidrug-resistant (MDR) A. baumannii biofilm. Riparin III, a natural alkamide derived from Aniba riparia (Nees) Mez., possesses various biological activities, including significant antimicrobial potential. Nonetheless, no reports are available on the use of this compound in conjunction with conventional antimicrobials. Hence, this study aimed to investigate the inhibition and eradication of A. baumannii MDR biofilm by combining riparin III and colistin, along with potential ultrastructural changes observed in vitro. Clinical isolates of A. baumannii, known for their robust biofilm production, were inhibited, or eradicated in the presence of the riparin III/colistin combination. Furthermore, the combination resulted in several ultrastructural alterations within the biofilm, such as elongated cells and coccus morphology, partial or complete disruption of the biofilm's extracellular matrix, and cells exhibiting cytoplasmic material extravasation. At the synergistic concentrations, the riparin III/colistin combination exhibited a low hemolytic percentage, ranging from 5.74% to 6.19%, exerting inhibitory and eradicating effects on the A. baumannii biofilm, accompanied by notable ultrastructural changes. These findings suggest its potential as a promising alternative for therapeutic purposes.

Biofortification of cow milk through dietary supplementation with sunflower oil: fatty acid profile, atherogenicity, and thrombogenic index.

The present study aimed to assess the effects of replacing the starchy ingredients of concentrate by increasing the levels of sunflower oil on the production, composition, fatty acid profile, and evaluate the atherogenicity and thrombogenic index of Jersey cow's milk. Eight Jersey cows were arranged in a double Latin square and distributed in treatments consisting of supplementation with increasing levels of sunflower oil replacing the corn grain and wheat bran of concentrate, including the following: T0 (control diet), without sunflower oil and with 38 g ether extract (EE)/kg dry matter (DM); T1 = 65 g EE/kg DM; T2 = 86 g EE/kg DM; and T3 = 110 g EE/kg DM. The daily milk production was measured, and the corrected milk production was calculated. Milk samples were analyzed by infrared spectroscopy to determine fat, protein, lactose, and total solids, whereas the lipid profile was assessed by gas chromatography. Milk production, energy-corrected milk production, fat content, daily fat production, lactose, and total solids were not affected by the treatments. Protein, lactose, and total solids concentrations decreased. Short-, medium-, and odd-chain fatty acids decreased with an increase in sunflower oil levels. Conversely, linear increases in long-chain, monounsaturated, and polyunsaturated fatty acid concentrations were observed. There were significant increases in stearic and elaidic acids and conjugated linoleic acid isomers, especially in vaccenic and rumenic acids. There was a positive effect on the milk atherogenicity, thrombogenicity, and nutraceutical indices. Dietary supplementation with sunflower oil changes the milk FA profile, decreases the atherogenicity and the thrombogenicity indices, and improve the nutraceutical index up to the addition of 86 g EE/kg DM de sunflower oil in the diets of Jersey cows.

Determining the Impacts of COVID-19 on Urban Deliveries in the Metropolitan Region of Belo Horizonte Using Spatial Analysis.

The COVID-19 pandemic has changed lifestyles, with consequent impacts on urban freight movements. This paper analyzes the impacts of COVID-19 on urban deliveries in the Belo Horizonte Metropolitan Region, Brazil. The Lee index and the Local Indicator of Spatial Association were calculated using data on urban deliveries (retail and home deliveries) and COVID-19 cases. The results confirmed the negative impacts on retail deliveries and the positive impacts on home deliveries. The spatial analysis demonstrated that the most interconnected cities presented more similar patterns. At the beginning of the pandemic, consumers were considerably concerned about the virus spread, and the changes in consumption behavior were slow. The findings suggest the importance of alternative strategies to traditional retail. In addition, the local infrastructure should adapt to the increased demand for home deliveries during pandemics.

Histogram analysis in the differentiation between adrenal adenomas and pheochromocytomas: the value of a single measurement.

Objective: To assess the diagnostic accuracy of histogram analysis on unenhanced computed tomography (CT) for differentiating between adrenal adenomas and pheochromocytomas (PCCs). Materials and Methods: We retrospectively identified patients with proven PCCs who had undergone CT examinations between January 2009 and July 2019 at one of two institutions. For each PCC, we selected one or two adenomas diagnosed within two weeks of the date of diagnosis of the PCC. For each lesion, two readers scored the size, determined the mean attenuation, and generated a voxel histogram. The 10th percentile (P10) was obtained from the conventional histogram analysis, as well as being calculated with the following formula: P10 = mean attenuation - (1.282 × standard deviation). The mean attenuation threshold, histogram analysis (observed) P10, and calculated P10 (calcP10) were compared in terms of their diagnostic accuracy. Results: We included 52 adenomas and 29 PCCs. The sensitivity, specificity, and accuracy of the mean attenuation threshold were 75.0%, 100.0%, and 82.5%, respectively, for reader 1, whereas they were 71.5%, 100.0%, and 81.5%, respectively, for reader 2. The sensitivity, specificity, and accuracy of the observed P10 and calcP10 were equal for both readers: 90.4%, 96.5%, and 92.6%, respectively, for reader 1; and 92.3%, 93.1%, and 92.6%, respectively, for reader 2. The increase in sensitivity was significant for both readers (p = 0.009 and p = 0.005, respectively). Conclusion: For differentiating between adenomas and PCCs, the histogram analysis (observed P10 and calcP10) appears to outperform the mean attenuation threshold as a diagnostic criterion.

Objetivo: Avaliar a acurácia diagnóstica da análise por histograma na tomografia computadorizada (TC) sem contraste para a diferenciação entre adenomas adrenais e feocromocitomas (FCCs). Materiais e Métodos: Identificamos, retrospectivamente, pacientes com diagnóstico de FCC confirmado que foram submetidos a exames de TC entre janeiro de 2009 e julho de 2019 em duas instituições distintas. Para cada FCC, selecionamos um ou dois adenomas diagnosticados em até duas semanas da data do diagnóstico do FCC. Para cada lesão, dois leitores pontuaram o tamanho, determinaram a atenuação média e geraram um histograma com os voxels das imagens. O percentil 10 (P10) foi obtido a partir da análise convencional do histograma, além de ser calculado com a seguinte fórmula: P10 = atenuação média - (1,282 × desvio-padrão). O limiar de atenuação média, o P10 da análise por histograma (P10 observado) e o P10 calculado (P10calc) foram comparados em termos de acurácia diagnóstica. Resultados: Foram incluídos 52 adenomas e 29 FCCs. A sensibilidade, especificidade e acurácia do limiar de atenuação média foram de 75,0%, 100,0% e 82,5% para o leitor 1, respectivamente, e de 71,5%, 100,0% e 81,5% para o leitor 2, respectivamente. A sensibilidade, especificidade e acurácia do P10 observado e do P10calc foram idênticas para os dois leitores: 90,4%, 96,5% e 92,6%, respectivamente, para o leitor 1; e 92,3%, 93,1% e 92,6%, respectivamente, para o leitor 2. O aumento da sensibilidade foi significativo para ambos os leitores (p = 0,009 e p = 0,005, respectivamente). Conclusão: Para a diferenciação entre adenomas e FCCs, a análise por histograma (P10 observado ou P10calc) parece superar o limiar de atenuação média como critério diagnóstico.

Presenteeism and noise perception at work: a cross-sectional study using association analysis

ABSTRACT BACKGROUND: Presenteeism refers to the presence of a worker at work with reduced performance due to illness, and it is a common public health problem. Exposure to noise during production processes brings risk to workers' health. OBJECTIVE: To analyze the health profile of workers in the automotive industry and identify the association between noise perception and presenteeism among workers in the Brazilian automotive industry. DESIGN AND SETTING: This was a cross-sectional study utilizing a case study design analyzing the automotive industry in the interior of São Paulo state, Brazil. METHODS: This study included 306 workers using the Presenteeism Work Limitations Questionnaire protocol. Multiple logistic regression was used for data analysis. RESULTS: Male workers with reports of headache, tension, and limited well-being at work, having perceived that noise exposure interferes with productivity, showed a positive association with the occurrence of presenteeism. Physical demand had the highest score in terms of interfering with the presenteeism index. CONCLUSION: Workers' perceptions of noise were associated with presenteeism.

Effects of stretch-shortening cycle fatigue protocol on lower limb asymmetry and muscle soreness in judo athletes.

This study aimed to analyse unilateral countermovement jumps (CMJ) performance and muscle soreness in lower limbs, as well as to compare lower limb asymmetry over 48h after a stretch-shortening cycle (SSC) fatigue protocol. Fourteen judo athletes performed unilateral CMJ on each leg before, and after the 5th and 10th sets over 24h and 48h of an SSC-fatigue protocol. The SSC protocol reduced CMJ performance after the 5th set and 10th sets, especially in the weaker limb (p < 0.05), but returned to the baseline values after 24h. Asymmetry increased for peak force, peak power, and mean power after the 5th set compared to the baseline (p < 0.05) and remained higher for peak force after the 10th set (p = 0.019), returning to the baseline values after 24h (p < 0.05). Soreness increased for the lower body at post, 24h, and 48h compared to the baseline (p < 0.05). In conclusion, a fatiguing SSC protocol can result in increased bilateral asymmetries in judo athletes, but after 24h and 48h of the protocol the bilateral asymmetry returned to the baseline values, with only muscle soreness still elevated.

Hubo mayor prevalencia en hombres (RP=1,38; IC 95%: 1,31; 1,45), mayor edad (RP=1,20; IC 95%: 1,07; 1,34), mayor carga de trabajo semanal (RP=1,10; IC 95%: 1,03). ;1,17) y los insatisfechos con el trabajo (RP=1,21; IC95%:1,15;1,27). Como factor protector, profesores con mayor experiencia docente (RP=0,92; IC95%:0,87;0,98) y contratados o nombrados (RP=0,89; IC95%:0,85;0,94). Conclusión: Se encontró inadecuación en el estilo de vida entre los maestros hombres y mayores, con jornadas laborales más largas e insatisfacción laboral.

RESUMO Objetivo: Analisar a prevalência e fatores associados ao perfil do estilo de vida dos professores da educação básica pública de Minas Gerais na pandemia da COVID-19. Método: Inquérito epidemiológico websurvey realizado com professores da educação básica pública de Minas Gerais. A coleta de dados ocorreu de agosto a setembro/2020 via formulário digital. Foram avaliadas as características antropométricas, sociodemográficas, laborais e estilo de vida. Utilizou-se a Regressão de Poisson. Resultados: Participaram 15.641 professores e 31,1% apresentaram hábitos inadequados de saúde. Houve maior prevalência entre homens (RP=1,38; IC95%:1,31;1,45), maior idade (RP=1,20; IC95%: 1,07;1,34), maior carga semanal de trabalho (RP=1,10; IC95%:1,03;1,17) e os insatisfeitos com o trabalho (RP=1,21; IC95%:1,15;1,27). Como fator de proteção encontraram-se os professores com mais tempo de trabalho docente (RP=0,92; IC95%:0,87;0,98) e contratados ou designados (RP=0,89; IC95%:0,85;0,94). Conclusão: Verificou-se inadequação do estilo de vida entre os professores homens mais velhos, com maior jornada laboral e insatisfação com o trabalho.

Biomarcadores vasculares em pacientes hipertensos / Vascular biomarkers in hypertensive patients

Fundamento: Avaliação da dinâmica vascular tem sido associada a uma melhor quantificação do risco cardiovascular de pacientes hipertensos. Objetivo: Avaliar a rigidez arterial em pacientes hipertensos acompanhados no ambulatório escola da Universidade Iguaçu, avaliar a dinâmica vascular e rigidez arterial desta população e propor estratégias para uma maior proteção cardiovascular destes pacientes. Métodos: Estudo prospectivo, aberto, avaliando a taxa de pacientes com pressão arterial sistólica central ≥120mmHg e ≤120mmHg; e a velocidade de onda pulso ≥10m/s e ≤10m/s através da avaliação de pacientes consecutivos atendidos no ambulatório escola, com >18 anos, no período de agosto/2019 a março/2020. Análise de dados demográficos, condições clínicas associadas e presença de outros fatores de risco. Todos os pacientes foram submetidos à avaliação dos parâmetros centrais e de rigidez arterial pela técnica oscilométrica. Análise estatística: análise descritiva dos dados em média com desvio padrão para as variáveis contínuas, epercentual do número total para as demais variáveis. As análises foram feitas com software Excel, versão 2101 (build 13628.20448 Microsoft Store). Resultados: 56 pacientes (44 femininos); média idade 56,08±12,24anos. Média de PA 135,08±15,73/85,39±10,30mmHg. Pacientes com pressão sistólica central ≥ 120mmHg: 32,14%; pacientes com a velocidade de onda de pulso ≥ 10m/s: 26,78%. Quantidade de medicamentos anti--hipertensivos por paciente com PASc ≥ 120mmHg: 1 droga (38,88%), 2 drogas (61,11%), 3 drogas (0%), > 3 drogas (0%). Quantidade de medicamentos anti-hipertensivos utilizados pelos pacientes com VOP ≥ 10m/s: 1 droga (26,66%), 2 drogas (66,67%), 3 drogas (6,67%), > 3 drogas (0%). Conclusão: Mais de um quarto da população apresentava elevação da PASc e da VOP. Cerca de 30% dos participantes que apresentavam VOP ≥10m/s estavam em sua maioria (74,34%) usando dois ou mais fármacos anti-hipertensivos em combinação livre. Estas informações implicam na n necessidade de reavaliação da estratégia terapêutica objetivando não apenas o alcance das metas de PA, mas a efetiva proteção CV (AU).

Background: Assessment of vascular dynamics has been associated with better quantification of cardiovascular risk in hypertensive patients. Objective: To evaluate arterial stiffness in hypertensive patients followed up at the Iguaçu University outpatient clinic, to evaluate the vascular dynamics and arterial stiffness of this population and to propose strategies for greater cardiovascular protection in these patients. Methods: Prospective, open study, evaluating the rate of patients with central systolic blood pressure ≥120mmHg and ≤120mmHg; and pulse wave velocity ≥10m/s and ≤10m/s through the evaluation of consecutive patients treated at the school outpatient clinic, aged >18 years, from August/2019 to March/2020. Analysis of demographic data, associated clinical conditions and presence of other risk factors. All patients underwent assessment of central parameters and arterial stiffness using the oscillometric technique. Statistical analysis:descriptive analysis of data in mean with standard deviation for continuous variables, and percentage of the total number for other variables. Analyzes were performed using Excel software, version 2101 (build 13628.20448 Microsoft Store) Results: 56 patients (44 female); mean age 56.08±12.24 years. Mean BP 135.08±15.73/85.39±10.30mmHg. Patients with central systolic pressure ≥ 120mmHg: 32.14%; patients with pulse wave velocity ≥ 10m/s: 26.78%. Number of antihypertensive drugs per patient with SBP ≥ 120mmHg: 1 drug (38.88%), 2 drugs (61.11%), 3 drugs (0%), > 3 drugs (0%). Number of antihypertensive drugs used by patients with PWV ≥ 10m/s: 1 drug (26.66%), 2 drugs (66.67%), 3 drugs (6.67%), > 3 drugs (0%) (AU).,
