Understanding the sources of variation in the use of high-cost technologies is important for developing effective strategies to control costs of care. Palliative radiation therapy (RT) is a discretionary treatment and its use may vary based on patient and clinician factors.
Using data from the SEER-Medicare linked database, we identified patients diagnosed with metastatic lung, prostate, breast, and colorectal cancers in 2010 through 2015 who received RT, and the radiation oncologists who treated them. The costs of radiation services for each patient over a 90-day episode were calculated, and radiation oncologists were assigned to cost quintiles. The use of advanced technologies (eg, intensity-modulated radiation, stereotactic RT) and the number of RT treatments (eg, any site, bone only) were identified. Multivariable random-effects models were constructed to estimate the proportion of variation in the use of advanced technologies and extended fractionation (>10 fractions) that could be explained by paechnologies and high-cost radiation services.
Metastatic renal cell carcinoma (mRCC) management guidelines recommend brain imaging if clinically indicated and the rate of occult central nervous system (CNS) metastasis is not well-defined. Early detection could have major therapeutic implications, because timely interventions may limit morbidity and mortality.
A retrospective review was performed to characterize patients with mRCC incidentally diagnosed with asymptomatic brain metastases during screening for clinical trial participation at Gustave Roussy and Memorial Sloan Kettering Cancer Center. Descriptive statistics and time-to-event methods were used to evaluate the cohort.
Across 68 clinical trials conducted between 2001 and 2019 with a median 14.1-month follow-up, 72 of 1,689 patients (4.3%) with mRCC harbored occult brain metastases. The International Metastatic RCC Database Consortium (IMDC) risk status was favorable (26%), intermediate (61%), and poor (13%), and 86% of patients had ≥2 extracranial sites of disease, including lung metastaseS involvement extends to those with favorable risk features per IMDC risk assessment. These data provide rationale for brain screening in patients with advanced RCC.
In the era of personalized medicine, cancer care is subject to major changes and innovations. click here It is unclear, however, to what extent implementation of such innovations and their impact on patient outcomes differ by health insurance type. This study compared provision of treatment and survival outcomes among patients with colorectal cancer (CRC) who had statutory health insurance (SHI) versus private health insurance (PHI) in Germany.
We analyzed patterns of CRC treatment (surgery, chemotherapy/radiotherapy, and targeted therapy) and survival in a large cohort of patients who were diagnosed with CRC in 2003 through 2014 and were observed for an average of 6 years. Associations of type of health insurance with treatment administration and with overall, CRC-specific, and recurrence-free survival were investigated using multivariable logistic and Cox proportional hazards models, respectively.
Of 3,977 patients with CRC, 427 (11%) had PHI. Although type of health insurance was not associated with treatment aor differences in uptake of targeted therapy between patients with PHI and those with SHI but no differences in patient survival after adjusting for relevant sociodemographic, clinical, and tumor characteristics. Further studies are needed on factors associated with the uptake of therapeutic innovations and their impact on patient survival by health insurance type.
Bodyweight-supporting treadmills are popular rehabilitation tools for athletes recovering from impact-related injuries because they reduce ground reaction forces during running. However, the overall metabolic demand of a given running speed is also reduced, meaning athletes who return to competition after using such a device in rehabilitation may not be as fit as they had been prior to their injury.
To explore the metabolic effects of adding incline during bodyweight-supported treadmill running.
Cross-sectional.
Research laboratory.
Fourteen apparently healthy, recreational runners (6 females and 8 males; 21 [3]y, 1.71 [0.08]m, 63.11 [6.86]kg).
The participants performed steady-state running trials on a bodyweight-supporting treadmill at 8.5mph. The control condition was no incline and no bodyweight support. All experimental conditions were at 30% bodyweight support. The participants began the sequence of experimental conditions at 0% incline; this increased to 1%, and from there on, 2% incline inining intensity while running on a bodyweight-supporting treadmill by introducing incline. Rehabilitation programs should rely on quantitative rather than qualitative data to drive exercise prescription in this modality.
The sensation of fatigue experienced at a certain point of the race is an important factor in the regulation of pacing. The rating of perceived exertion (RPE) is considered one of the main mediators utilized by athletes to modify pacing. The aim was to analyze the relationship between pacing and RPE of elite open water swimmers during national indoor pool championships.
A total of 17 elite open water swimmers (males, n = 9; females, n = 8) agreed to provide RPE every 500m during the finals of the national championships 5-km indoor pool race. Time splits, stroke rate, and RPE were collected every 500m. The Hazard score was calculated by multiplying the momentary RPE by the remaining fraction of the race. Athletes were placed in one of two categories medalists or nonmedalists. For all variables, separate mixed analysis of variances (P ≤ .05) with repeated measures were used considering the splits (ie,every 500m) as within-subjects factor and the groups (ie,medalists and nonmedalists) as between-subjects factor.
Average swimming speed showed a significant main effect for split for both males and females (P < .001). A significant interaction was observed between average swimming speed and groups for females (P = .032). RPE increased in both groups (P < .001) with no difference observed between groups. However, the female nonmedalists showed a disproportionate nonlinear increase in RPE (5.20 [2.31]) halfway through the event that corresponded to the point where they started significantly decreasing speed.
The results of the present study show different pacing strategies adopted by medalists and nonmedalists despite a similar RPE.
