To evaluate oncological and reproductive outcomes of women undergoing fertility-sparing surgery (FSS) for stage II-III serous borderline ovarian tumors (BOTs).
A multi-institutional retrospective study was conducted within the MITO Group.
A total of 91 patients were recruited. The median follow-up time from primary cytoreduction was 127 months (IQR range 91-179). Forty-nine patients (53.8%) experienced at least one recurrence (median time to first relapse 22 months, IQR range 9.5-57). At univariable analysis, significant predictors of relapse were size of largest extra-ovarian lesion, peritoneal cancer index, completeness of cytoreduction, type of implants. After multivariable analysis, the size of extra-ovarian lesions and the presence of invasive implants resulted as the only independent predictors of recurrence. Median disease-free survival (DFS) was 96 months (95% CI, 24.6-167.3), while median disease-specific survival (DSS) was not reached. Twenty-nine patients (31.8%) attempted to conceive 20 (68.9%) achieved at least one pregnancy and 18 (62%) gave birth to a healthy child. At the end of the observation period, 88 patients (96.7%) showed no evidence of disease, 2 (2.2%) were alive with disease, and 1 patient (1.1%) died from BOT.
Despite the recurrence high rate, FSS provides good chances of reproductive success with no impact on DSS. The presence of invasive peritoneal implants affects the DFS but not DSS nor reproductive outcome. The risk of recurrence would not seem to be related to the ovarian preservation per se, but to the natural history of the initial peritoneal spread.

Secondary hyperparathyroidism, a condition of excess parathyroid hormone (PTH, Pth) production, is often seen in chronic kidney disease (CKD) patients with elevated fibroblast growth factor 23 (FGF23, Fgf23). Elevated FGF23 levels stimulate secondary hyperparathyroidism-associated parathyroid αKlotho signaling. As overexpression of rationally selected microRNAs can suppress target gene activation, we hypothesized that microRNA-based suppression of parathyroid FGF23/αKlotho axis activity may be a potential strategy to combat secondary hyperparathyroidism.
In vitro luciferase assays and human parathyroid adenoma cell experiments were used to determine miR-129-1-3p's effects on αKlotho expression in vitro. We also studied the effects of parathyroid-specific miR-129-1 overexpression (miR-129Ox) in CKD and non-CKD mice and parathyroid tissue cultures derived therefrom.
miR-129-1-3p directly targets the αKlotho mRNA strand in human parathyroid cells. miR-129Ox CKD mice and control CKD mice displayed comparable serum levels of calcium, phosphate, Fgf23, and 1,25-dihydroxyvitamin D (1,25(OH)
D). However, miR-129Ox CKD mice displayed reduced parathyroid αKlotho expression and lower circulating Pth levels. In vitro culture of miR-129Ox CKD murine parathyroid tissue showed suppressed responses to Fgf23, with decreased Pth secretion and diminished cell proliferation after four days.
miR-129 negatively regulates pro-proliferative, Pth-inducing Fgf23/αKlotho signaling in the parathyroid glands of CKD mice.

However, the very specific nature of acute lymphoblastic leukemias and their treatment in children and adolescents led the Leukemia Committee of the French Society for the fight against Cancers and leukemias in children and adolescents (SFCE) to propose more specific recommendations. Here is the second version of these recommendations updated according to the evolution of knowledge on COVID19.Coal is an important energy source worldwide. Objectively and accurately predicting coal consumption is conducive to healthy coal industry development, because such predictions can provide references and warnings that are useful in formulating energy strategies and implementing environmental policies. Population size and area economic development are the main factors that affect coal consumption. Considering the above influences, this paper first establishes a differential equation and proposes a novel multivariable Verhulst grey model (MVGM(1,N)) based on grey information differences. MVGM(1,N) extends classical model from single-variable to multivariate and diminishes the characteristics of Verhulst's reliance on saturated S-shaped and single-peak data, making classical model more applicable to real situations. To prove the effectiveness of MVGM(1,N) simulation experiments are carried out in areas with high coal consumption. The result of this proposed model is more precise than that of NLARX, ARIMA and five classical grey models Finally, this novel multivariable model predicates coal consumption of Inner Mongolia and Gansu Provinces in China, the results show that MVGM(1,N) is preferable to other models, indicating that this model can effectively predict coal consumption.The work described herein compares the performance of different optimized controllers, viz. proportional-integral, proportional-integral-derivative (PID) with filter, two-degree-of-freedom (2DOF)-PID, 3DOF-PID, fractional-order-PID, cascade PI-PID, tilt-integral-derivative (TID), and cascade-TID (CC-TID) controllers in frequency regulation of a hybrid energy distributed power system (HEDPS). The HEDPS is integrated with a multi-unit hydrothermal power plant for ensuring stable power supply. Crow search algorithm has been adopted with chaotic mapping (CCSA) for fine-tuning of the controller settings mentioned above. Extensive analysis has been presented to confirm the superiority of the CC-TID controller compared to other prevalent controllers of state-of-art in terms of different performance specifications. The tuning competence of the CCSA has been demonstrated over conventional CSA and other available optimization techniques. To enhance the mastery of the controller, disturbance-observer (Dob) is developed to estimate fast-changing disturbance profiles and subsequently refines the control law. The controller's robustness is affirmed under random perturbations, presence of nonlinearities, and variation of parameters. The effect of integration of a geothermal power plant on the system performance has also been outlined. The efficacy of Dob-aided CC-TID controller in frequency regulation is validated thereof.The Practice Guidelines Committee of the American Society of Transplantation and Cellular Therapy partnered with its Transplant Infectious Disease Special Interest Group to update its 2009 compendium-style infectious diseases guidelines for hematopoietic cell transplantation (HCT). A completely fresh approach was taken, with the goal of better serving clinical providers by publishing each stand-alone topic in the infectious diseases series in a concise format of frequently asked questions (FAQs), tables, and figures [1]. Adult and pediatric infectious diseases and HCT content experts developed and then answered FAQs, and then finalized topics with harmonized recommendations that were made by assigning a strength of recommendation ranging from A to E paired with a level of supporting evidence graded I to III. The first topic in the series focuses on potentially life-threatening infections in HCT caused by Enterobacterales, relevant infection risk factors, and practical considerations regarding prevention and treatment of these infections in the setting of emerging multidrug resistance.Data on stem cell transplantation (SCT) for Diamond-Blackfan Anemia (DBA) is limited. We studied patients transplanted for DBA and registered in the EBMT database. Between 1985 and 2016, 106 DBA patients (median age, 6.8 years) underwent hematopoietic stem cell transplantation from matched-sibling donors (57%), unrelated donors (36%), or other related donors (7%), using marrow (68%), peripheral blood stem cells (20%), both marrow and peripheral blood stem cells (1%), or cord blood (11%). The cumulative incidence of engraftment was 86% (80% to 93%), and neutrophil recovery and platelet recovery were achieved on day +18 (range, 16 to 20) and +36 (range, 32 to 43), respectively. Three-year overall survival and event-free survival were 84% (77% to 91%) and 81% (74% to 89%), respectively. Older patients were significantly more likely to die (hazard ratio, 1.4; 95% confidence interval, 1.06 to 1.23; P less then .001). Outcomes were similar between sibling compared to unrelated-donor transplants. XMU-MP-1 nmr The incidence of acute grades II to IV of graft-versus-host disease (GVHD) was 30% (21% to 39%), and the incidence of extensive chronic GVHD was 15% (7% to 22%). This study shows that SCT may represent an alternative therapeutic option for transfusion-dependent younger patients.Immunoglobulin D (IgD) multiple myeloma (MM) is a rare subtype of MM that carries a worse prognosis than non-IgD subtypes. Compared with non-IgD subtypes, IgD MM is associated with a shorter survival time. The application of chimeric antigen receptor (CAR) T-cell therapy for patients with relapsed or refractory multiple myeloma (R/R MM) has increasing evidence as an efficacious treatment. This study was designed to investigate efficacy and safety of chimeric antigen receptor (CAR) T-cell therapy for relapsed/refractory IgD MM (R/R IgD MM). In this single-arm, phase 2 trial, patients diagnosed with R/R IgD MM were infused with either a combination of anti-B-cell maturation antigen and anti-CD19 CAR T-cells or anti-CD19 CAR T-cells alone, with subsequent evaluation of therapeutic response and treatment-related toxicities. At the data cutoff date, 7 patients were enrolled in our study, and all patients achieved response based on the International Myeloma Working Group Uniform Response Criteria. Six patients achieved stringent complete remission (sCR) within 60 days after CAR T-cell infusion (median time 58 days, range 18 to 90 days), and 1 patient with extramedullary disease achieved minimal response (MR) at 30 days after infusion. Bone marrow minimal residual disease (MRD) negativity was achieved in all patients, and the median time to achieve MRD negativity was 22 days (range 14 to 60 days). The most common grade 3 to 4 treatment-related toxicities were hematological toxicities. All patients experienced cytokine release syndrome (CRS), although CAR T-cell-related neurotoxicity was not observed. In our study, CAR T-cell therapy showed encouraging efficacy in the patients with R/R IgD MM, achieving high rates of sCR and MRD negativity. Aside from CRS and prolonged hematologic toxicities, other adverse reactions were mild, suggesting that this is a well-tolerated treatment with a high therapeutic potential.Steroid-refractory (SR) lower gastrointestinal (LGI) acute graft-versus-host disease (aGVHD) has poor prognosis, and novel drugs are needed. We describe outcomes of patients with SR-LGI aGVHD treated with vedolizumab. The primary objective was to determine overall response rate (ORR) at days 14, 28, and 56. Secondary outcomes included overall survival (OS), non-relapse mortality and toxicities. Twenty patients, median age 46 years (range, 23-71), were included. All but 2 patients (90%) had grade 3 to 4 aGVHD (45% stage 4, 40% stage 3 LGI). Median time to vedolizumab was 21 days (range, 5-1031) and 13 days (range, 0-533) after diagnosis of LGI aGVHD and SR-LGI aGVHD, respectively. It was given as ≥3rd line (median 3; range 2-6) in 75% after failure of steroids, and additional treatments including ruxolitinib (n = 12) and others. Median follow-up was 17 months (range, 10-34). The days 14, 28 and 56 ORRs were 45% (9/20; complete response [CR] 25%), 35% (7/20; CR 20%), and 25% (5/20; CR 20%), respectively. Among ruxolitinib failures, it was 50% (6/12; CR 25%), 50% (6/12; CR 25%) and 25% (3/12; CR 16.
