PurposeShort bowel syndrome (SBS) is a serious rare disorder that is usually managed with parenteral nutrition. Central venous catheter (CVC)-related complications are known to occur, but their incidence rates (IRs) in Japan are unknown. The aim of this study was to estimate the incidence of complications in Japanese patients with CVCs, including patients with SBS using CVCs.Patients and methodsA retrospective cohort study in 64,817 patients with CVCs, including 81 patients with SBS, between April 2008 and October 2016 using a claims database in Japan was conducted. IRs of complications were calculated as total events divided by total catheter-days among all patients with CVCs and among patients with SBS.ResultsThe majority (>90%) of patients in the CVC and SBS cohorts were ≥18 years old. Overall, IRs of any type of complication were numerically higher in patients with SBS compared with all patients with CVCs (2.68 vs 1.95 cases per 1,000 catheter-days, respectively). Among patients with SBS, septicemia, infection, and inflammatory reaction were the only complications observed. The complications with the highest incidence were catheter-related bloodstream infections (CRBSIs) in both the overall CVC cohort and the SBS cohort with IRs of 1.35 and 2.68 cases per 1,000 catheter-days, respectively. The IR of any CVC-related complication was numerically higher in patients with SBS with cancer vs without cancer (3.44 vs 1.86 cases per 1,000 catheter-days, respectively).ConclusionOur study quantifies the incidence of complications in patients with CVCs, including those with SBS, in Japan.
Objectives: Cervical cancer-related morbimortality and survival is marked by inequalities across different geographical areas. We investigated the association between macroregion of residence and survival in women diagnosed with cervical cancer who underwent cancer treatment in the public health system (SUS) between 2002 and 2015 in Minas Gerais, Brazil. Methods: Non-concurrent prospective study with data from the National Database in Oncology (Base Onco), developed through deterministic-probabilistic pairing of SUS information systems. We identified women aged over 18 years, diagnosed with cervical cancer between 2002 and 2010, who underwent radiotherapy and/or chemotherapy and who were living in Minas Gerais. We estimated five-year overall and cancer-specific survival probabilities by the Kaplan-Meier method. Extended Cox models were employed to assess the association between macroregion of residence and overall and cancer-specific death risk. Results: A total of 5,613 patients were included. Five-year overall and cancer-
6589 Background: While patients with cancer are known to be at increased risk of infection in part due to the immunocompromising nature of cancer treatments, recent data indicate a particularly high risk for COVID-19 infection and poor outcomes (Wang et al., 2020). A recent study (Meltzer et al., 2020) demonstrated Vitamin D deficiency may increase risk of COVID-19 infection, and a small randomized controlled trial in Spain reported significant improvement in mortality among hospitalized patients treated with calcifediol. Vitamin D deficiency has been reported in two leading causes of cancer deaths: breast and prostate. In this study, we performed a retrospective cohort analysis on nationally representative electronic medical records (EMR) to assess whether Vitamin D deficiency affects risk of COVID-19 among these patients. Methods: Patients with breast (female) or prostate (male) cancer were identified between 3/1/2018 and 3/1/2020 from EMR data provided pro-bono by the COVID-19 Research Database ( covid19researchdatabase.org ). Patients with an ICD-10 code for Vitamin D deficiency or < 20ng/mL 20(OH)D laboratory result within 12 months prior to 3/1/2020 were classified as Vitamin D deficient. COVID-19 diagnosis was defined using ICD-10 codes and laboratory results for COVID-19 at any time after 3/1/2020. Logistic regressions, adjusting for baseline demographic and clinical characteristics, were conducted to estimate the effect of Vitamin D deficiency on COVID-19 incidence in each cancer cohort. Results: A total of 16,287 breast cancer and 14,919 prostate cancer patients were included in the study. The average age was 68.9 years in the breast cancer cohort and 73.6 years in the prostate cancer cohort. The breast cancer cohort consisted of 85% Whites, 13% Black or African Americans, and less than 5% of other races. A similar race distribution was observed in the prostate cancer cohort. Unadjusted analysis showed the risk of COVID-19 was higher among Vitamin D deficient patients compared to non-deficient patients in both cohorts (breast: OR = 1.60 [95% C.I.: 1.15, 2.20]; prostate: OR = 1.59 [95% C.I.: 1.08, 2.33]). Similar findings were observed when assessed in subgroups of patients with newly diagnosed cancer in the dataset, as well as after adjusting for baseline characteristics. Conclusions: Our study suggests breast and prostate cancer patients may have an elevated risk of COVID-19 infection if Vitamin D deficient. These results support findings by Meltzer et al., 2020 demonstrating a relationship between Vitamin D deficiency and COVID-19 infection. While a randomized clinical trial is warranted to confirm the role for Vitamin D supplementation in preventing COVID-19, our study underscores the importance of monitoring Vitamin D levels across and within cancer populations, particularly in the midst of the global COVID-19 pandemic.
