tential novel therapeutic approaches employing the administration of hormonal or anti-hormonal therapy in combination with antiviral drugs in COVID-19 patients.Primary central nervous system lymphoma is a rare aggressive disease that largely affects elderly patients and is associated with poor prognosis. The optimal treatment approach is not yet defined and it consists of induction and consolidation phases. The combination of high-dose (HD) methotrexate-based chemotherapy followed by whole-brain radiotherapy (WBRT) prolongs the median progression-free survival (PFS) and overall survival 2- to 3-fold as compared to WBRT alone but is associated with significant delayed neurotoxicity. Alternative strategies are being investigated in order to improve disease outcomes and spare patients the neurocognitive side effects. These include reduced-dose WBRT, non-myeloablative HD chemotherapy, or HD chemotherapy with autologous stem cell transplantation (HDC/ASCT). There are no randomized studies that compare all these consolidation regimens head to head but recently HDC/ASCT has been evaluated versus WBRT in prospective randomized studies. These studies proved that WBRT and HDC/ASCT yield similar 2-year PFS with preserved or improved cognitive function after HDC/ASCT. Yet, the proportion of patients treated with such intensive consolidation is low, both in real life and in specialized centers, leaving many unsettled issues. This review is appraising current dilemmas related to the choice of consolidating therapeutic modalities, their associated acute and delayed toxicity, and future prospects for alternative approaches in the elderly.

To assess whether biopsy of multiparametric magnetic resonance imaging (MRI)-negative lobes can be avoided without compromising significant cancer (SC) detection among men with unilateral MRI-positive lobes.

From April 2013 to April 2019, 322 men with elevated prostate-specific antigen (PSA <20 ng/mL) and unilateral MRI-positive lobes underwent targeted 4-core and systematic 14-core biopsy. MRI findings were prospectively collected and evaluated according to the Prostate Imaging-Reporting and Data System (PI-RADS) version 2, and scores ≥3 were considered positive. SC was defined as Gleason score ≥3 + 4 or maximal cancer length ≥5 mm. We developed predictive models of overall cancer and SC in MRI-negative lobes and evaluated the performance of these models.

Detection rates of overall cancer/SC were 69%/61% for the overall cohort, 58%/48% for MRI-positive lobes, and 36%/20% for MRI-negative lobes. Age ≥75 years, PSA density ≥0.3, and PI-RADS ≥4 were independently predictive of both overall cancer and SC in MRI-negative lobes; 1 point was assigned for each risk factor, and the predictive score was defined as the sum of points (0-3) for both overall cancer and SC. Areas under the curve of the model for overall cancer/SC were 0.67/0.71. In the decision curve analysis, the model was of value above the threshold probability of 13%/6% for detecting overall cancer/SC in MRI-negative lobes. Of 40 men with score 0, overall cancer/SC was detected in the MRI-negative lobe in 4 (10%)/1 (2.5%).

Biopsies of MRI-negative lobes may be avoided without compromising SC detection using our predictive model.

As CRH-binding protein (CRHBP) SNP rs1500 was associated with reduced cocaine abuse after 1 year in methadone maintenance treatment (MMT) for heroin addiction, we evaluated the association of additional 28 selected SNPs, in 17 stress-related genes, with MMT outcome.

The distribution of genotypes of each SNP by cocaine abuse after 1 year in MMT was assessed under the dominant and recessive models using χ2. Cumulative retention (up to 26.5 years) was studied using Kaplan-Meier analyses. Logistic regression and Cox model were used for multivariate analyses.

Of a nonselective sample of 404 patients, 25 patients with <50% Europeans/Middle Eastern ancestry were excluded. Of the remaining 379 patients, 330 (87.1%) stayed at least 1 year in treatment. Four SNPs were associated with cocaine abuse after 1 year in MMT. Tefinostat A lower proportion of cocaine abusers was found in the groups of subjects with the following genotypes arginine vasopressin (AVP) SNP rs2282018 CC, CRHBP rs7728378 TT, galanin rs3136541 TT/TC, an following genotypes arginine vasopressin (AVP) SNP rs2282018 CC, CRHBP rs7728378 TT, galanin rs3136541 TT/TC, and neuropeptide Y receptor Y1 (NPY1R) rs4518200 AA. The following independent variables were associated with lack of cocaine in urine after 1 year (multivariate analyses) CRHBP rs7728378 TT, NPY1R rs4518200 AA, no cocaine in urine on admission, as well as opiate and benzodiazepine use after 1 year in MMT. Cumulative retention (n = 379) was longer in carriers of AVP rs2282018 CC (13.7 years, 95% CI 11.1-16.2) versus TT/TC genotypes (10.5, 95% CI 9.4-11.5) (p = 0.0230) Conclusions The study suggests that a reduction in cocaine abuse and longer retention among MMT patients is mediated in part by variants in stress-related genes and is a step toward precision medicine.The flight of monarch butterflies is characterized by a relatively large wing, flapping at a relatively low frequency coupled with abdomen undulation. This paper presents the dynamics of a flapping wing flyer that can be applied to the coupled motion of the wing, body, and abdomen at the monarch butterfly scale, which is formulated directly on the configuration manifold. The resulting thorax and abdomen motion as well as the resultant forces are consistent with the flight of a live monarch butterfly. Based on these, beneficial effects of the abdomen undulation in the flight of monarch butterflies are illustrated. For both hover and forward-climbing trajectories, the abdomen undulation results in a reduction of the energy and power consumption. Furthermore, the Floquet stability analysis shows that the periodic orbits associated with both flight modes are stable. In particular, the abdomen undulation improves the stability. Compared to the dynamics of hawkmoth, bumblebee, and fruitfly models, the monarch possesses superior stability properties.
