Remote Activity Monitoring and Electronic Patient-Reported Outcomes Collection During Radiotherapy for Head and Neck Cancer: A Pilot Study.

PURPOSE: Modern wearable devices provide objective and continuous activity data that could be leveraged to enhance cancer care. We prospectively studied the feasibility of monitoring physical activity using a commercial wearable device and collecting electronic patient-reported outcomes (ePROs) during radiotherapy (RT) for head and neck cancer (HNC). METHODS: Patients planned for a course of external beam RT with curative intent for HNC were instructed to use a commercial fitness tracker throughout the RT course. During weekly clinic visits, physician-scored adverse events were recorded during using Common Terminology Criteria for Adverse Events version 4.0, and patients completed ePRO surveys using a clinic tablet or computer. Feasibility of activity monitoring was defined as collection of step data for at least 80% of the RT course for at least 80% of patients. Exploratory analyses described associations between step counts, ePROs, and clinical events. RESULTS: Twenty-nine patients with HNC were enrolled and had analyzable data. Overall, step data were recorded on 70% of the days during patients' RT courses, and there were only 11 patients (38%) for whom step data were collected on at least 80% of days during RT. Mixed effects linear regression models demonstrated declines in daily step counts and worsening of most PROs during RT. Cox proportional hazards models revealed a potential association between high daily step counts and both reduced risk of feeding tube placement (hazard ratio [HR], 0.87 per 1,000 steps, P < .001) and reduced risk of hospitalization (HR, 0.60 per 1,000 steps, P < .001). CONCLUSION: We did not achieve our feasibility end point, suggesting that rigorous workflows are required to achieve continuous activity monitoring during RT. Although limited by a modest sample size, our findings are consistent with previous reports indicating that wearable device data can help identify patients who are at risk for unplanned hospitalization.

The Impact of Door to Diuretic Time in Acute Heart Failure on Hospital Length of Stay and In-Patient Mortality.

Background Acute heart failure (AHF) can be life-threatening if not treated promptly and can significantly increase the number of annual emergency department (ED) encounters in the United States. Achieving adequate and prompt euvolemic state in AHF patients using intravenous (IV) diuretics is the cornerstone of treatment, which not only reduces in-hospital stay and mortality but also decreases healthcare expenditures. Surprisingly, the door to diuretic (D2D) time in AHF patients has always been a debatable issue among physicians worldwide, and so far, there are no set guidelines. This study examines a large cohort of AHF patients to determine the association between diuretics use within 90 minutes of ED admission and hospital length of stay (LOS) and patient mortality.  Methods Retrospective institutional data of AHF patients receiving IV diuretics following ED admission were extracted from 2016 to 2017. A total of 7,751 patients treated for AHF exacerbation were included, which were further divided into two groups based on the timing of diuretics administration (<90 minutes vs. ≥90 minutes). The primary outcomes were LOS between the two groups and hospital mortality. The standard statistical methodology was used for data analysis. Results  A total of 7,751 AHF cases receiving IV diuretics were identified. Almost 1,432 patients (18.5%) received IV diuretics within 90 minutes of ER admission (group 1) while 6,319 patients (81.5%) patients received IV diuretics after 90 minutes (group 2). Furthermore, among group 1 patients, average LOS was noted to be associated with shorter hospitalization (average of 1.423 days less as compared to group 2 patients (confidence interval (CI) =1.02-1.82; p<0.05). Finally, after controlling for other mortality risk factors, patients in group 2 were 1.435 times more likely to have died compared to patients in group 1 (CI=1.03-1.98; p<0.05). Conclusions  D2D time in AHF patients has always been a crucial judgmental decision. The current study successfully demonstrated the relation between IV diuretics administration within 90 minutes of ED admission, favorable clinical outcomes, and decreased mortality rates. More adequately powered studies are needed to validate the results of our current study further.

The Conversion of Wolff-Parkinson-White (WPW) Pattern into WPW Syndrome in the Presence of Ischemia: A Case Report.

Wolff-Parkinson-White (WPW) syndrome is defined by the presence of a short PR interval, delta waves on the electrocardiogram (EKG), and symptomatic tachycardia. The condition is rare but can be life-threatening if not recognized in a timely manner. The WPW pattern on EKG can mask ischemic changes and may also increase the risk of arrhythmia and subsequent mortality. Our case describes the conversion of an underlying WPW pattern into WPW syndrome in the scenario of an acute myocardial infarction (AMI).
