Overhydration and low serum prealbumin predict peritoneal dialysis-related peritonitis in continuous ambulatory peritoneal dialysis patients

Abstract Background In this study, we focused on the role of overhydration (OH) and low serum prealbumin concentration in predicting 3-year peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patientsMethods We measured serum prealbumin concentration and OH by body composition monitor on 278 CAPD patients (159 males and 119 females) to predict 3-year peritonitis. We created the baseline demographics of all patients with the mean age of 46 years and the median peritoneal dialysis (PD) duration of 21 months.Results After the 3-year follow-up, 44 patients diagnosed PD-related peritonitis (15.8%). Low education, serum albumin, prealbumin, high CRP-hs and OH were independent risk factors for predicting peritonitis during 36 months in CAPD patients. Based on the Kaplan–Meier analysis, we realized that patients with low prealbumin and high OH were the good predictors of 3-year peritonitis in CAPD patients (Prealbumin: AUC = 0.838, cut-off value = 32.5 mg/dL, Se = 90.9%, OH: AUC = 0.851, cut-off value = 1.33 L, Se = 79.5%, Sp = 85.5%), (Log-rank test p < 0.001).Conclusion Overhydration and low serum prealbumin level were the good predictors of PD-related peritonitis in CAPD patients.

Abstract OBJECTIVE There is no standard treatment for recurrent ependymoma. This study aimed to investigated the role of radiotherapy in recurrent ependymoma. METHODS Retrospective analysis was performed on 49 cases of recurrent ependymoma diagnosed in Guangdong Sanjiu Brain Hospital from January 2008 to July 2020. Overall survival (OS) was calculated by Kaplan-Meier method and tested by Log-rank test. P < 0.05 was considered statistically significant. RESULTS The median age was 7 years (range:1-57 yrs). Nineteen patients were with ependymoma WHO grade II while 30 were with grade III, respectively. Recurrence treatment: 14 cases received re-surgery, 23 cases received radiotherapy, among them 16 cases received re-radiotherapy. To May, 2021, the median follow-up time was 35 months (range 3-153). Median PFS time was 17 months after initial diagnosis, median PFS time was 8 months after treatment to recurrence disease, Median OS time is 39 months, and median OS time is 20 months after recurrence. The median survival time for recurrence was 48 months vs. 11 months (P =0.001) in the radiotherapy group vs. non-radiotherapy group,res; Re-radiotherapy combined with chemotherapy vs reradiotherapy alone (0.194); RRT combined with anti-angiogenesis therapy vs. RRT alone (0.688). CONCLUSION Radiotherapy can prolong the survival time of recurrent ependymoma, and concurrent therapy as chemotherapy or anti-angiogenesis therapy with RT does not seem to improve the prognosis. Therefore, radiotherapy can be used as the main treatment for recurrent ependymoma.

Background. To determine risk factors that influence peritonitis event on patients with Continuous Ambulatory Peritoneal Dialysis (CAPD) in Sanglah Hospital, thus, we can prevent the occurrence of peritonitis in CRF patients with CAPD. Methods. This is a retrospective cohort study, which was conducted at the Sanglah Hospital in Denpasar from August to September 2016. All data are processed using SPSS 17.0 for Windows, data analysis by using the Kaplan Meier (K-M) curves, hypothesis using the log-rank test, while for the survival is by using the median or mean survival. The significance is determined by the value of p < 0.05 with 95% CI. Results. A total of 78 people (46 men and 32 women) who meet the inclusion criteria of this study. Thirteen people (16.7%) are experiencing peritonitis. K-M Survival Curves between in CRF patients with CAPD, with Age ≥ 50 years (51.36 months survival rates, 95% CI 44.79 until 57.93) with < 50 years (56.1 months Survival rates, 95% CI 51.41 until 60.78) with RR 2.54 log-rank p 0.084. K-M Survival Curves between in CRF patients with CAPD, with DM (mean 52.63 months survival rates, 95% CI 47.21 until 58.06) with No DM (56.88 months survival rates, 95% CI 52.89 until 60.88) with RR 4.16 and 0.037 log-rank p. Conclusion. There is a correlation between DM and the incidence of peritonitis in CRF patients with CAPD at Sanglah Hospital. However, age and education level are not related.

Ctnnb1 Mutation

10016 Background: Recently, a wait and see (W&S) approach has been proposed for patients affected by desmoid tumor (DT). Specific CTNNB1 mutation has been correlated with higher risk of recurrence after surgical resection. Aim of this study was to evaluate the correlation between CTNNB1 mutation type and time to progression in patients primarily observed (TTP). Methods: We included all consecutive patients:(1) primarily observed at the Fondazione IRCSS Istituto Nazionale Tumori (Milano, Italy) or Institut Gustave Roussy (Paris, France) for primary sporadic DTs (2) with available FFPE preserved tissue for CTNNB1 mutational analysis, (3) with measurable disease and adequate follow-up. TTP from date of diagnosis to date of radiological (PRO-R) or symptomatic (PRO-S) progression were conducted by Kaplan-Meier method and log-rank test to compare strata. Results: A total of 79 patients (August 2002- July 2011) were included (81% female, 19% male); median age was 34 (IQ, 10-77); sites distribution: abdominal/chest wall (75%), extremity (21%), intra-abdominal (4%). CTNNB1 mutations were observed in 76% of DT samples: 41A (48%), 45F (25%), 45P (2%); 24% were WT. Median follow-up was 19 mo (IQ, 11-28). Thirty-six patients experienced progression (86% PRO-R, 14% PRO-S): 41A (47%), 45F (55%), 45P (100%), WT (26%). An inferior TTP at 36 months was observed in mutated patients vs WT, while no difference was detected for specific subtype mutated patients (WT 68%, 45F 24%, 41/45P 35%, p= 0.045). A variety of different treatments including surgery, hormonal therapy, chemotherapy, antiCOX2 or persistent W&S approach were proposed at progression. Forty-two patients did not receive any treatment. Conclusions: A clear trend towards a lower risk of progression was observed in WT patients, but no difference between specific mutated patients (45F vs 41/45P) was observed. Prospective studies to eventually clarify the potential role of CTNNB1 as prognostic tool in tailoring desmoids treatment are presently underway.

Chirurgische Entfernung

Die komplette chirurgische Entfernung von Lebermetastasen bietet Patienten nach kolorektalem Karzinom die einzige kurative Chance. Es gibt jedoch eine, anscheinend unbegrenzte, Anzahl an Parametern, die die Prognose dieser Patienten bestimmen und damit den Sinn dieser Therapie vorhersagen können. Zu den am häufigsten diskutierten und am einfachsten zu bestimmenden Parametern gehört die Anzahl der Metastasen. Ziel dieser Studie war es daher die Wertigkeit dieses Parameters in der Literatur zu reflektieren und unsere eigenen Patientendaten zu evaluieren. Insgesamt konnte von 302 Patienten ein komplettes Follow-up erhoben werden. Die gebildeten Patientengruppen wurden mit Hilfe einer Kaplan Meier Analyse und konsekutivem log rank Test untersucht. Die Literatur wurde bis Dezember 1998 revidiert. Die Anzahl der Metastasen bestätigte sich als ein prognostisches Kriterium. Lagen drei oder mehr Metastasen vor, so war nicht nur die Wahrscheinlichkeit einer R0 Resektion deutlich geringer (17.8% versus 67.2%) sondern auch das Überleben der Patienten nach einer R0 Resektion tendenziell unwahrscheinlicher. Das 5-Jahres Überleben betrug bei > 2 Metastasen 9% bei > 2 Metastasen 36%. Das 10-Jahres Überleben beträgt bislang bei > 2 Metastasen 0% bei > 2 Metastasen 18% (p < 0.07). Die Anzahl der Metastasen spielt in der Prognose der Patienten mit kolorektalen Lebermetastasen eine Rolle. Selbst bei mehr als vier Metastasen ist jedoch gelegentlich eine R0 Resektion möglich. In diesen Fällen kann der Patient auch langfristig von einer Operation profitieren. Das wichtigere Kriterium einer onkologisch sinnvollen Resektabilität ist die Frage ob technisch und funktionell eine R0 Resektion durchführbar ist. Ist das der Fall, so sollte auch einem Patienten mit mehreren Metastasen die einzige kurative Chance einer Resektion nicht vorenthalten bleiben.

Introduction: The aim of this study was to examine whether the use of an internal electrostimulator could improve the results obtained with core decompression alone in the treatment of osteonecrosis of the femoral head. Methods: We performed a retrospective study of 41 patients (55 hips) treated for osteonecrosis of the femoral head between 2005 and 2014. Mean follow-up time was 56 (12-108) months. We recorded 3 parameters: time to recurrence of pain, time to conversion to arthroplasty and time to radiographic failure. Survival was estimated using the Kaplan-Meier method. The equality of the survival distributions was determined by the Log rank test. Results: Implanted electrostimulator was a factor that increased the survival of hips in a pre-op Steinberg stage of II or below, while it remained unchanged if the stage was III or higher. Conclusions: The addition of an internal electrostimulator provides increased survival compared to core decompression alone at stages below III.
