Coronavirus-2019 (COVID-19) mortality is higher in patients with cancer than in the general population, yet the cancer-associated risk factors for COVID-19 adverse outcomes are not fully characterized.
 
  We reviewed clinical characteristics and outcomes from patients with cancer and concurrent COVID-19 at Memorial Sloan Kettering Cancer Center until March 31, 2020 (n = 309), and observed clinical end points until April 13, 2020. We hypothesized that cytotoxic chemotherapy administered within 35 days of a COVID-19 diagnosis is associated with an increased hazard ratio (HR) of severe or critical COVID-19. In secondary analyses, we estimated associations between specific clinical and laboratory variables and the incidence of a severe or critical COVID-19 event.
 
  Cytotoxic chemotherapy administration was not significantly associated with a severe or critical COVID-19 event (HR, 1.10; 95% CI, 0.73 to 1.60). Hematologic malignancy was associated with increased COVID-19 severity (HR, 1.90; 95% CI, 1.30 to 2.80). ID-19 outcomes. Patients with active hematologic or lung malignancies, peri-COVID-19 lymphopenia, or baseline neutropenia had worse COVID-19 outcomes. Interactions among antineoplastic therapy, cancer type, and COVID-19 are complex and warrant further investigation.
  The development of highly effective targeted agents for chronic lymphocytic leukemia offers the potential for fixed-duration combinations that achieve deep remissions without cytotoxic chemotherapy.
 
  This phase II study tested a combination regimen of obinutuzumab, ibrutinib, and venetoclax for a total of 14 cycles in both patients with treatment-naïve (n = 25) and relapsed or refractory (n = 25) chronic lymphocytic leukemia to determine the response to therapy and safety.
 
  The primary end point was the rate of complete remission with undetectable minimal residual disease by flow cytometry in both the blood and bone marrow 2 months after completion of treatment, which was 28% in both groups. The overall response rate at that time was 84% in treatment-naïve patients and 88% in relapsed or refractory patients. At that time, 67% of treatment-naïve patients and 50% of relapsed or refractory patients had undetectable minimal residual disease in both the blood and marrow. At a median follow-up of 24.2 months in treatment-naïve patients and 21.5 months in relapsed or refractory patients, the median progression-free and overall survival times were not yet reached, with only 1 patient experiencing progression and 1 death. Neutropenia and thrombocytopenia were the most frequent adverse events, followed by hypertension. Grade 3 or 4 neutropenia was experienced by 66% of patients, with more events in the relapsed or refractory cohort. There was only 1 episode of neutropenic fever. A favorable impact on both perceived and objective cognitive performance during treatment was observed.
 
  The combination regimen of obinutuzumab, ibrutinib, and venetoclax offers time-limited treatment that results in deep remissions and is now being studied in phase III cooperative group trials.

  The majority of lower extremity amputations (LEAs) are the result of diabetes or peripheral vascular disease. There is a paucity of literature on individuals' experiences living with dysvascular LEAs in the community, particularly in Canada. The purpose of this study was to explore the perceptions and experiences of community-dwelling adults living with dysvascular LEA.
 
  Semi-structured qualitative interviews were conducted with individuals with a dysvascular LEA recruited from three rehabilitation hospitals. Participants were included if they were English-speaking adults at least three months post-amputation and no longer receiving inpatient rehabilitation. Sampling was purposive to ensure variation by gender, level of amputation, and geographic location. Data were analyzed using an inductive content-analysis approach.
 
  Thirty-five interviews were completed with individuals with dysvascular LEA. Study participants portrayed LEA as having an impact on many aspects of their lives, resulting in changes in teeds.
 Our findings highlight the impacts of dysvascular LEA in peoples' lives. Future research is warranted to explore how community-based interventions and strategies can address the ongoing needs of individuals with dysvascular LEA. Implications for rehabilitation Our findings highlight the long-term impacts of dysvascular lower extremity amputations, which resulted in changes in mobility, social activities and roles, and psychological wellbeing. Participants identified issues in access to community services and resources, including rehabilitation. Mechanisms to identify people at risk for social isolation need to be developed and implemented in rehabilitation centers. Access to ongoing rehabilitation services in the community are needed to optimize mobility outcomes and address ongoing psychological needs.The SARS-CoV-2 pandemic has led to a global decrease in personal protective equipment (PPE), especially filtering facepiece respirators (FFRs). Ultraviolet-C wavelength is a promising way of decontamination, however adequate dosimetry is needed to ensure balance between over and underexposed areas and provide reliable results. Our study demonstrates that UVGI light irradiance varies significantly on different respirator angles and propose a method to decontaminate several masks at once ensuring appropriate dosage in shaded zones. An UVGI irradiator was built with internal dimensions of 69.5 × 55 × 33 cm with three 15 W UV lamps. Inside, a grating of 58 × 41 × 15 cm was placed to hold the masks. Two different flat fold respirator models were used to assess irradiance, four of model Aura 9322 3 M of dimensions 17 × 9 × 4 cm (tri-fold), and two of model SAFE 231FFP3NR (bi-fold) with dimensions 17 × 6 × 5 cm. An STN-SilverNova spectrometer was employed to verify wavelength spectrum and surface irradiance.  https://www.selleckchem.com/products/dexketoprofen-trometamol.html  A simulation was performed to find the irradiance pattern inside the box and the six masks placed inside.
