    Due to the threat of extinction of Amburana cearensis, a tree of medicinal importance for the Northeastern Brazil, a phytochemical analysis was performed with specimens obtained by seed germination. Ten compounds were isolated and identified by spectroscopic methods and comparison with literature data. p-Hydroxybenzoic acid, ayapin, (E/Z)-melilotosides are being reported for the first time for the genus, besides coumarin, isokaempferide, vanillic acid, protocatechuic acid, amburosides A and B which have already been found in the trunk bark. Based on physical and NMR spectroscopy evidences the structures of several melilotosides already described in the literature have been suggested to be revised

    Este artigo buscou analisar a ocorrência de complicações pós-operatórias em pacientes submetidos à abdominoplastia, evidenciando os tipos mais frequentes, a incidência e as possíveis etiologias. A abdominoplastia possui como objetivo remover a pele em excesso e apertar os músculos abdominais soltos mediante a dissecção limitada do retalho abdominal, plicatura da fáscia do reto abdominal e ressecção tridimensional de um segmento de pele e tecido subdérmico até a fáscia de Scarpa. Mesmo sendo um dos procedimentos cirúrgicos mais realizados no mundo, os riscos de complicações não devem ser ignorados. Esses, comumente, se relacionam às comorbidades do paciente e à escolha técnica cirúrgica associada à experiência do cirurgião. Dentre as possíveis complicações, destacam-se seroma, infecção da ferida operatória, hematoma, deiscência de sutura, necrose de pele, hipertrofia cicatricial, trombose venosa profunda, embolia pulmonar e insatisfação com o resultado. No entanto, ainda são necessários estudos que explorem os impactos que a abdominoplastia, como cirurgia eletiva, pode desencadear na saúde e qualidade de vida do paciente

    Neoadjuvant Chemotherapy plus Interval Cytoreductive Surgery with or without Hyperthermic Intraperitoneal Chemotherapy (NIHIPEC) in the Treatment of Advanced Ovarian Cancer: A Multicentric Propensity Score Study

    Simple Summary Advanced ovarian cancer (Stages III-IV) continues to be one of the gynecological tumors with the highest mortality. Standard treatment consists of debulking surgery and subsequent adjuvant chemotherapy. Recently, some authors have postulated that the administration of hyperthermic chemotherapy during surgery could increase the survival of patients, especially in cases in which chemotherapy had already been administered before surgery to reduce tumor volume. Our study is important because it collects data from 11 tertiary hospitals in Spain, and the data are subjected to a statistical technique that reproduces the data that we would find in a prospective study but using retrospective data (propensity score matching). It also offers a current view of the status of ovarian cancer treatment in our country.Abstract Introduction: Epithelial ovarian cancer (EOC) is primarily confined to the peritoneal cavity. When primary complete surgery is not possible, neoadjuvant chemotherapy (NACT) is provided; however, the peritoneum-plasma barrier hinders the drug effect. The intraperitoneal administration of chemotherapy could eliminate residual microscopic peritoneal tumor cells and increase this effect by hyperthermia. Intraperitoneal hyperthermic chemotherapy (HIPEC) after interval cytoreductive surgery could improve outcomes in terms of disease-free survival (DFS) and overall survival (OS). Materials and Methods: A multicenter, retrospective observational study of advanced EOC patients who underwent interval cytoreductive surgery alone (CRSnoH) or interval cytoreductive surgery plus HIPEC (CRSH) was carried out in Spain between 07/2012 and 12/2021. A total of 515 patients were selected. Progression-free survival (PFS) and OS analyses were performed. The series of patients who underwent CRSH or CRSnoH was balanced regarding the risk factors using a statistical analysis technique called propensity score matching. Results: A total of 170 patients were included in each subgroup. The complete surgery rate was similar in both groups (79.4% vs. 84.7%). The median PFS times were 16 and 13 months in the CRSH and CRSnoH groups, respectively (Hazard ratio (HR) 0.74; 95% CI, 0.58-0.94; p = 0.031). The median OS times were 56 and 50 months in the CRSH and CRSnoH groups, respectively (HR, 0.88; 95% CI, 0.64-1.20; p = 0.44). There was no increase in complications in the CRSH group. Conclusion: The addition of HIPEC after interval cytoreductive surgery is safe and increases DFS in advanced EOC patients

    The Prevalence of Sarcopenia in the Elderly: How the Consumption of Protein Supplement Interacts in Individuals of a Fortaleza Institution

    Introduction: Sarcopenia is a natural disturb that usually affects older people consisting in strength and muscle mass loss. Sedentary lifestyle and nutritional habits are some inducing factors. Supplementation may contribute to improvements on life quality in elders predisposed to sarcopenia. Objectives: verify the relevance of protein supplementation on life quality of elders predisposed to sarcopenia. Assess the individual's evolution along the study. Methods: protein supplementation application during 45 days on 13 elders, comparing them with 13 elders in control group without supplementation. Anthropometric measurements were performed before and after the 45 days period and evaluated for each participant, as well as their nutrition, individually. Results: We observed a improvement in some anthropometric measures, and a reduction in others, that might be explained by previous pathologies already diagnosed. Muscle mass changes were positive, according with specific reference measures. Some elders reported motor strength improvements, disposition and energy. Physical active participants showed more significant results and sedentary ones. Conclusion: positive outcomes were obtained from protein supplementation in older people, and more correlated studies are still necessary, considering the field's relevancy to longevity and overall life quality

    North Atlantic simulations in Coordinated Ocean-ice Reference Experiments phase II (CORE-II). Part I: Mean states

    Simulation characteristics from eighteen global ocean–sea-ice coupled models are presented with a focus on the mean Atlantic meridional overturning circulation (AMOC) and other related fields in the North Atlantic. These experiments use inter-annually varying atmospheric forcing data sets for the 60-year period from 1948 to 2007 and are performed as contributions to the second phase of the Coordinated Ocean-ice Reference Experiments (CORE-II). The protocol for conducting such CORE-II experiments is summarized. Despite using the same atmospheric forcing, the solutions show significant differences. As most models also differ from available observations, biases in the Labrador Sea region in upper-ocean potential temperature and salinity distributions, mixed layer depths, and sea-ice cover are identified as contributors to differences in AMOC. These differences in the solutions do not suggest an obvious grouping of the models based on their ocean model lineage, their vertical coordinate representations, or surface salinity restoring strengths. Thus, the solution differences among the models are attributed primarily to use of different subgrid scale parameterizations and parameter choices as well as to differences in vertical and horizontal grid resolutions in the ocean models. Use of a wide variety of sea-ice models with diverse snow and sea-ice albedo treatments also contributes to these differences. Based on the diagnostics considered, the majority of the models appear suitable for use in studies involving the North Atlantic, but some models require dedicated development effort
