Analysis of 4725 Cases of Gluteal Augmentation with Intramuscular Fillers: A Clinical Cohort Study.

Background: In recent years, the aesthetic market has become more prominent for being not only a tool to correct unwanted features but also a social means for improving quality of life. The use of 30% polymethylmethacrylate (PMMA) as a gluteal filler has grown in popularity all over the world, being sought after by men and women for body remodeling because it provides a natural look as well as significant long-lasting results. Methods: A retrospective, multicenter study analyzed the medical records of 2801 patients who underwent a total of 4725 gluteal filler procedures between January 2009 and December 2021 at the different locations of Clínica Leger. The study protocol was approved by the Brazilian National Research Ethics Commission. Results: The medical records of 2801 patients (2666 women and 135 men) who underwent 4725 gluteal filler injections were retrospectively analyzed. A total of 922,776 mL of PMMA was used (average = 329 mL/patient). The occurrence of 101 adverse events (2.1%) was observed, and no statistically significant relationship between the mean injected volume and the incidence of complications could be found. Conclusions: According to the data presented in this study, the use of PMMA injections with the appropriate volumes for aesthetic treatments and corrections is safe and effective.

Fetal ductal constriction caused by maternal ingestion of green tea in late pregnancy: an experimental study.

OBJECTIVES: The aim of this study was to test the hypothesis that experimental maternal intake of green tea in late pregnancy causes fetal ductus arteriosus constriction, probably because of prostaglandin inhibition. METHODS AND RESULTS: Twelve fetal lambs (pregnancy > 120 days) were assessed before and after maternal administration of green tea (n = 8) or water (n = 4; controls) as the only source of liquid. After 1 week, echocardiography showed signs of constriction of the ductus arteriosus in all fetuses from mothers ingesting green tea, with increase in mean systolic velocity(from 0.70 ± 0.19 m/s to 0.92 ± 0.15 m/s, 31.4%, p = 0.001) and mean diastolic velocity (0.19 ± 0.05 m/s to 0.31 ± 0.01 m/s, 63.1%, p < 0.001), decrease of pulsatility index (2.2 ± 0.4 to 1.8 ± 0.3, 22.2%, p = 0.003) and increase of mean right ventricular/left ventricular diameter ratio (0.89 ± 0.14 to 1.43 ± 0.23, 60.6%, p < 0.001). In the four control fetuses, there were no significant changes. All lambs exposed to green tea also showed at autopsy dilated and hypertrophic right ventricles, which was not present in control fetuses. Histological analysis showed a significantly larger mean thickness of the medial avascular zone of the ductus arteriosus in fetuses exposed to green tea than in controls (747.6 ± 214.6 µm vs 255.3 ± 97.9 µm, p < 0.001). CONCLUSIONS: This study in fetal lambs shows a cause and effect relationship between experimental maternal exposure of green tea and fetal ductus arteriosus constriction in late pregnancy.

Pressão arterial de 24 horas em mulheres idosas normotensas e com hipertensão do avental branco / 24-hour blood pressure in normotensive elderly women and elderly women with white-coat hypertension

FUNDAMENTO: Mudanças no comportamento do ritmo circadiano podem ser deletérias, levando à lesão de órgãos-alvo, o que sugere ser de importante significado prognóstico e, eventualmente, podem também demandar intervenção terapêutica. OBJETIVO: Descrever e comparar os ritmos circadianos de pressão arterial (PA) entre mulheres idosas normotensas e portadoras de hipertensão do avental branco (HAB). MÉTODOS: Estudo transversal em uma amostra de 36 pacientes, com idades entre 60-83 anos, submetidas à monitorização ambulatorial de pressão arterial (MAPA) durante 24 horas. Dezenove idosas normotensas e 17 com HAB foram comparadas quanto à queda noturna e variabilidade de PA, ascensão matinal da PAS, pressão de pulso, hipotensão pós-prandial e correlação de médias de PA de 24 horas. Na análise estatística, utilizou-se o teste t de Student, teste do qui-quadrado, teste exato de Fisher e teste de correlação linear de Pearson. RESULTADOS: As idosas com HAB apresentaram níveis mais elevados de PAS do que as normotensas, entre 8-12 horas (133 ± 8,0 mmHg vs 123 ± 9,0 mmHg, respectivamente, p < 0,001). A variabilidade da PA foi mais elevada no grupo de HAB apenas no período de vigília (entre 7-23 horas, p = 0,02). Constatou-se correlação positiva entre o IMC e as médias de PAS, à noite, apenas nas idosas com HAB (r = 0,578; p = 0,015 e r = 0,488; p = 0,055, respectivamente). CONCLUSÃO: As idosas portadoras de HAB apresentaram médias de PAS e PAD mais elevadas na vigília. Nas primeiras horas da manhã, as idosas com HAB apresentaram médias significativamente mais altas de PAS.

BACKGROUND: Changes in the behavior of the circadian rhythm can be deleterious, leading to target-organ damage, which suggests that they can have a prognostic significance and, eventually, can also demand therapeutic intervention. OBJECTIVE: To describe and compare the circadian rhythms of blood pressure (BP) in normotensive elderly women and in those with white-coat hypertension (WCH). METHODS: A cross-sectional study was carried out in sample of 36 patients, aged 60-83 years, submitted to ambulatory blood pressure monitoring (ABPM) for a period of 24 hours. Nineteen normotensive elderly women and 17 with WHC were compared regarding the nocturnal dipping and the BP variability, morning increase in systolic blood pressure (SBP), pulse pressure, post-prandial hypotension and correlation of 24-hour BP means. The statistical analysis used the Student's t test, Chi-square test, Fisher's exact test and Pearson's linear correlation. RESULTS: The elderly women with WCH presented higher levels of SBP than the normotensive ones, between 8 am-12 pm (133 ± 8.0 mmHg vs 123 ± 9.0 mmHg, respectively, p < 0.001). The BP variability was higher in the WCH group only during the wakefulness period (between 7 am-11 pm, p = 0.02). A positive correlation was observed between the BMI and the SBP means at night, only in the elderly women with WCH (r = 0.578; p = 0.015 and r = 0.488; p = 0.055, respectively). CONCLUSION: The elderly women with WCH presented higher SBP and diastolic blood pressure (DBP) means during the wakefulness period. In the early hours of the morning, the elderly women with WCH presented significantly higher SBP means.

Prevalência das lesões intra-epiteliais escamosas em exame ci´tológico numa determinada população de Santo Angelo, RS / Prevalence of squamous intraepithelial lesions in cutologic smear in a specific population of Santo Angelo, RS

No Brasil, o câncer cervical está entre as quatro primeiras taxas de incidência e mortalidade, representando um sério problema de saúde pública que pode ser evitado se lesões pré cancerosas forem detectadas precocemente. Observações epidemiológicas sugerem que o HPV seja o principal fator de risco do câncer cervical. O Objetivo deste estudo foi determinar a prevalência das lesões por HPV em uma determinada população de Santo Angelo, pela citologia. Foram analisados 472 exames citológicos no período de agosto de 2001 a janeiro de 2002. Desses exames, 449 (95,13 por cento) foram negativos para malignidade, 6 (1,27 por cento.
