RÉSUMÉ

BACKGROUND: Patients with cancer may be at high risk of adverse outcomes from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed a cohort of patients with cancer and coronavirus 2019 (COVID-19) reported to the COVID-19 and Cancer Consortium (CCC19) to identify prognostic clinical factors, including laboratory measurements and anticancer therapies. PATIENTS AND METHODS: Patients with active or historical cancer and a laboratory-confirmed SARS-CoV-2 diagnosis recorded between 17 March and 18 November 2020 were included. The primary outcome was COVID-19 severity measured on an ordinal scale (uncomplicated, hospitalized, admitted to intensive care unit, mechanically ventilated, died within 30 days). Multivariable regression models included demographics, cancer status, anticancer therapy and timing, COVID-19-directed therapies, and laboratory measurements (among hospitalized patients). RESULTS: A total of 4966 patients were included (median age 66 years, 51% female, 50% non-Hispanic white); 2872 (58%) were hospitalized and 695 (14%) died; 61% had cancer that was present, diagnosed, or treated within the year prior to COVID-19 diagnosis. Older age, male sex, obesity, cardiovascular and pulmonary comorbidities, renal disease, diabetes mellitus, non-Hispanic black race, Hispanic ethnicity, worse Eastern Cooperative Oncology Group performance status, recent cytotoxic chemotherapy, and hematologic malignancy were associated with higher COVID-19 severity. Among hospitalized patients, low or high absolute lymphocyte count; high absolute neutrophil count; low platelet count; abnormal creatinine; troponin; lactate dehydrogenase; and C-reactive protein were associated with higher COVID-19 severity. Patients diagnosed early in the COVID-19 pandemic (January-April 2020) had worse outcomes than those diagnosed later. Specific anticancer therapies (e.g. R-CHOP, platinum combined with etoposide, and DNA methyltransferase inhibitors) were associated with high 30-day all-cause mortality. CONCLUSIONS: Clinical factors (e.g. older age, hematological malignancy, recent chemotherapy) and laboratory measurements were associated with poor outcomes among patients with cancer and COVID-19. Although further studies are needed, caution may be required in utilizing particular anticancer therapies. CLINICAL TRIAL IDENTIFIER: NCT04354701.

RÉSUMÉ

BACKGROUND: Competitive sports training causes structural and conductive system changes manifesting by various electrocardiographic alterations. We undertook this study to assess the prevalence of abnormal ECG in trained Indian athletes and correlate it with the nature of sports training, that is endurance or strength training. METHODS: We evaluated a standard resting, lying 12 lead Electrocardiogram (ECG) in 66 actively training Indian athletes. Standard diagnostic criteria were used to define various morphological ECG abnormalities. RESULTS: 33/66 (50%) of the athletes were undertaking endurance training while the other 33 (50%) were involved in a strength-training regimen. Overall 54/66 (81%) sportsmen had significant ECG changes. 68% of these changes were considered as normal training related features, while the remaining 32% were considered abnormal. There were seven common training related ECG changes-Sinus Bradycardia (21%), Sinus Arrhythmia (16%), 1st degree Atrioventricular Heart Block (6%), Type 1 2nd-degree Atrioventicular Heart Block (3%), Incomplete Right bundle branch block (RBBB) (24%), Early Repolarization (42%), Left Ventricular Hypertrophy (LVH) (14%); while three abnormal ECG changes--T-wave inversion (13%), RBBB(4%), Right ventricular hypertrophy (RVH) with strain (29%) were noted. Early repolarization (commonest change), sinus bradycardia, and incomplete RBBB were the commoner features noticed, with a significantly higher presence in the endurance trained athletes. CONCLUSION: A high proportion of athletes undergoing competitive level sports training are likely to have abnormal ECG recordings. Majority of these are benign, and related to the physiological adaptation to the extreme levels of exertion. These changes are commoner during endurance training (running) than strength training (weightlifting).

RÉSUMÉ

About 30 to 46% of patients with major depressive disorder (MDD) fail to fully respond to initial antidepressants. Treatment-resistant depression (TRD) is a severely disabling disorder with no proven treatment options; novel treatment methods like rTMS can be used as augmentation to ongoing pharmacotherapy or as a solitary method of treatment. To evaluate the utility of repetitive transcranial magnetic stimulation as an augmenting method in TRD. In an open-label study, 21 patients with DSM-IV MDD without psychotic features who had failed to respond to an adequate trial of at least 2 antidepressants were given rTMS therapy for 4 weeks, keeping the dose of pre-existing antidepressants unchanged. High-frequency (10 Hz) stimulations were delivered over left dorsolateral prefrontal cortex at intensity of 110% of patient's motor threshold. Treatment response was defined as a reduction in score on the Hamilton Rating Scale for Depression (HAM-D) from baseline to end of treatment. Secondary efficacy measures included scores on the Clinical Global Impressions-Change and -Severity scales. At the end of 4 weeks, 19 patients completed the 4-week study and were assessed. In ITT analysis, the mean HAM-D17 scores were reduced from 30.80±5.00 to 19.00±6.37 (t=8.27, P<0.001). Only four patients reported headache, but there was no discontinuation due to adverse effects. The study indicates the potential utility of rTMS as an augmenting agent in TRD. Adequately powered, randomized controlled trials are necessary to evaluate the role of rTMS in TRD.

RÉSUMÉ

OBJECTIVE: This study was undertaken to determine the cost of initial hospital care for newborn infants according to gestational age at birth and survival status. STUDY DESIGN: This was a retrospective review of prospectively collected data on hospital and physician costs for all infants born in the study institutions at < or = 32 weeks' gestation for 1989 through 1992. A cohort of term and near-term infants was selected at random. Variables were examined by multiple logistic regression for their independent effects on cost. RESULTS: Length of stay and gestational age were related to cost among survivors born at < or = 32 weeks' gestation but not among nonsurvivors. Total cost of initial care for the US population of neonates is estimated at $10.2 billion annually, with 11.9% spent on infants born between 24 and 26 weeks' gestation and 42.7% spent on those born at > or = 37 weeks' gestation. CONCLUSIONS: Although costs for an individual surviving extremely premature baby may be high, the costs for extremely low gestational age infants is a small component of total neonatal care costs because so few infants are born at these gestational ages. The mathematic model developed from these data allows cost savings to be predicted for management strategies designed to alter gestational age at birth or survival.
