The Temporal Variability of the Freshwater Discharge and Water Levels at the Patos Lagoon,Brazil

引用

International Journal of Geosciences 2012年第4期3卷 758-766页

作者： Wiliam Correa marques Instituto de Matematica Estatistica e FisicaUniversidade Federal do Rio GrandeRio Grande do SulBrazil

The direct influence of freshwater discharge along the coastal regions is observed in several processes following a wide spectrum on spatial and temporal variability. The knowledge of relative importance of this physical forcing is fundamental by the correct management of the coastal sites and the understanding of consequences associated with processes of climatic order is one point deserves some investigation. The major part of the studies in the Patos Lagoon, located in the southernmost part of Brazil, is limited to investigate the effects in synoptic time scales. In this way, the objective of this study is to investigate the long term variability pattern of the Patos Lagoon discharge and water levels indentifying long term trends through wavelet analysis. The results indicated that El Ni?o (La Ni?a) events promote the intensification (decrease) of the freshwater intensity in the principal river tributaries of the Patos Lagoon following scales from 16 to 120 months (from 1.3 to 10 years). The most energetic cycle is centered in periods of 64 months (5.3 years). The longer events reflect the long term response of the non linear dynamics in Equatorial Pacific changing the precipitation pattern, principally during winter and at the end of spring and early autumn. The non-linear long term trend indicates a pattern with values of discharge normally above (below) the mean after (before) 1970’s. An increasing trend starting after 1970 possibly indicates a longer term cycle influencing the interannual variability of the Patos Lagoon discharge. The seasonality is maintained in climatic monthly means obtained after and before 1970’s, but, with mean increase around 364 m3·s?1 in freshwater discharge with reduced amplitude of the seasonal cycle.

Repeat hepatectomy for recurrent colorectal liver metastases:A comparative analysis of short-and long-term results

引用

Hepatobiliary & Pancreatic Diseases International 2022年第2期21卷 162-167页

作者： Paulo Figueiredo Costa Fabricio Ferreira Coelho Vagner Birk Jeismann Jaime Arthur Pirola Kruger Gilton marques Fonseca Ivan Cecconello Paulo Herman Digestive Surgery Brazilian College of Digestive Surgery(Colégio Brasileiro de Cirurgia Digestiva-CBCD) São PauloBrazil Digestive Surgery Division Department of GastroenterologyUniversity of São Paulo School of MedicineSão PauloBrazil Instituto do Câncer do Estado de São Paulo(ICESP) São PauloBrazil

Background: Liver recurrence after resection of colorectal liver metastases(CRLM) is frequent. Repeat hepatectomy has been shown to have satisfactory perioperative results. However, the long-term outcomes and the benefts for patients with early recurrence have not been clarifed. The aim of this study was to compare the short-and long-term outcomes of patients undergoing single hepatectomy and repeat hepatectomy for CRLM. Additionally, the oncological outcomes of patients with early( ≤ 6 months) and late recurrence who underwent repeat hepatectomy were compared. Methods: Consecutive adult patients undergoing hepatectomy for CRLM between June 20 0 0 and February 2020 were included and divided into two groups: single hepatectomy and repeat hepatectomy. Results: A total of 709 patients were included: 649 in the single hepatectomy group and 60 in the repeat hepatectomy group. Patients in the repeat hepatectomy group underwent more cycles of preoperative chemotherapy [4(3-6) vs. 3(2-4), P = 0.003]. Patients in the single hepatectomy group more frequently underwent major hepatectomies(34.5% vs. 16.7%, P = 0.004) and had a greater number of lesions resected(2.9 ± 3.6 vs. 1.9 ± 1.8, P = 0.011). There was no increase in operative time, estimated blood loss, length of hospital stay, complications, or mortality in the repeat hepatectomy group. There were no differences in overall survival( P = 0.626) and disease-free survival( P = 0.579) between the two groups. Similarly, for patients underwent repeat hepatectomy, no difference was observed between the early and late recurrence groups in terms of overall survival( P = 0.771) or disease-free survival( P = 0.350). Conclusions: Repeat hepatectomy is feasible and safe, with similar short-and long-term outcomes when compared to single hepatectomy. Surgical treatment of early liver recurrence offers similar oncological outcomes to those obtained for late recurrence.
