Acute effect on ambulatory blood pressure from aerobic exercise: a randomised cross-over study among female cleaners

Purpose: High occupational physical activity (OPA) is shown to increase the risk for elevated blood pressure, cardiovascular diseases and mortality. Conversely, aerobic exercise acutely lowers the blood pressure up to 25 h post exercise. However, it is unknown if this beneficial effect also apply for workers exposed to high levels of OPA. Cleaners constitute a relevant occupational group for this investigation because of a high prevalence of OPA and cardiovascular disease. Accordingly, the objective was to investigate the acute effects on ambulatory blood pressure from a single aerobic exercise session among female cleaners. Methods: Twenty-two female cleaners were randomised to a cross-over study with a reference and an aerobic exercise session. Differences in 24-h, work hours, leisure time, and sleep ambulatory blood pressure (ABP) were evaluated using repeated measure 2 × 2 mixed-models. Results: After the aerobic exercise session, the 24-h systolic ambulatory blood pressure was significantly lowered by 2.4 mmHg (p &lt; 0.01) compared to the reference session. The 24-h diastolic ABP was unaltered. During work hours, a lowered systolic ABP of 2.2 mmHg (p = 0.02) and a higher diastolic ABP of 1.5 mmHg (p = 0.03) were found after the aerobic exercise session. During leisure time, the systolic ABP was lowered by 1.7 mmHg (p = 0.04) and the diastolic ABP was unaltered. During sleep, the systolic and diastolic ABP was unaltered. Conclusion: A single aerobic exercise session lowered 24-h systolic ABP of 2.4 mmHg. Thus, an aerobic exercise session seems to be beneficial for lowering the risk of hypertension among cleaners.</p

Manifestações bucais em pacientes submetidos à quimioterapia

Em decorrência da quimioterapia, alterações na cavidade oral podem ser observadas e levar a complicações sistêmicas importantes, podendo aumentar o tempo de internação hospitalar, os custos do tratamento e afetar diretamente a qualidade de vida dos pacientes. Este trabalho teve como objetivo realizar uma pesquisa em um hospital de oncologia da cidade de Juiz de Fora (MG), sendo realizado através de coleta de dados nos prontuários de pacientes que estiveram em tratamento oncológico, onde foram avaliadas as prevalências das manifestações orais em relação ao sexo, idade e tipo de tumor. Verificou-se que a mucosite foi a manifestação mais incidente em ambos os sexos em todas as faixas etárias (15,5%). A xerostomia e as demais lesões, como candidíase e lesões aftosas, também estiveram presentes. É possível melhorar a qualidade de vida antes, durante e após as terapias antineoplásicas através de um protocolo de atendimento odontológico que inclua medidas de condicionamento do meio bucal prévia à quimioterapia, como profilaxia, remoção de cáries, tratamento periodontal e de focos periapicais, orientação para higiene oral e dieta, e ainda laserterapia. É importante a inserção do dentista na equipe oncológica para o diagnóstico precoce das manifestações bucais e acompanhamento no período de tratamento.Several changes in the oral cavity due to chemotherapy can be observed and can lead to important systemic complications, increasing the time of the patient in hospital and the costs of the treatment as well as affect the quality of life of the patients. The aim of this study was to assess the oral manifestation in patients treated with chemoterapy according to sex, age and tumor type. Data was collected in an oncology hospital in Juiz de Fora, Minas Gerais State, from patients' records that were submitted to oncologic treatment. It was possible to verify that mucositis, associated or not to other type of lesions, was the most common lesion in both sex of all ages (15.5%). Xerostomia and other lesions, such as Candida infection and aphthous lesions, were also present. It is possible to improve the quality of life of the patient during and after anti-neoplastic therapies through a protocol of odontological assistance that includes changes of the oral environment previous to chemotherapy such as profilaxis, caries removal, treatment of periodontal and periapical lesions, oral hygiene instructions, diet orientation and laser therapy. It is very important the insertion of the dentist in the oncologic medical team for the early diagnosis of the oral manifestation and follow-up during treatment time
