Ethnicity, cortisol, and experimental pain responses among persons with symptomatic knee osteoarthritis.
This study aimed to examine the relationship between cortisol and pain responses during a cold-pressor task (CPT) among African American (AA) and non-Hispanic White (NHW) adults with knee osteoarthritis (OA). Consistent with previous findings in young healthy adults, cold-pressor pain responses are related to pre-CPT cortisol concentrations in NHW persons with knee OA but not in their AA counterparts.

Magnesium, hemostasis, and outcomes in patients with intracerebral hemorrhage.
The researchers tested the hypothesis that admission serum magnesium levels are associated with hematoma volume, hematoma growth, and functional outcomes in patients with intracerebral hemorrhage (ICH). Their findings support the hypothesis that magnesium exerts a clinically meaningful influence on hemostasis in patients with ICH.

Information needs of older women with early-stage breast cancer when making radiation therapy decisions.
The researchers identified the information older women with early-stage breast cancer need when making radiation therapy decisions, and who patients identify as the main decision maker. They found that older women consider themselves to be the main decision maker; they desire information and have more agency and input in the decision-making process than prior literature would suggest.

Adaptive anatomical preservation optimal denoising for radiation therapy daily MRI.
An innovative method, adaptive anatomical preservation optimal denoising (AAPOD), was developed for optimal image denoising, i.e., to maximally reduce noise while preserving the tissue boundaries. The experimental results demonstrated that AAPOD was capable of reducing noise adaptively and optimally while avoiding tissue boundary losses.

Comparative effectiveness of chemotherapy vs resection of the primary tumour as the initial treatment in older patients with Stage IV colorectal cancer.
The objectives were to determine trends in the use of chemotherapy as the initial treatment and to evaluate the comparative effectiveness of initial chemotherapy vs resection of the primary tumor on survival (intention-to-treat analysis) in Stage IV colorectal cancer (CRC). Instrumental variable analysis found that, compared with resection, chemotherapy as the initial treatment offers similar or better 2-year survival in patients with Stage IV CRC.

Estimating the risks of breast cancer radiotherapy: evidence from modern radiation doses to the lungs and heart and from previous randomized trials.
The researchers estimated the absolute long-term risks of modern breast cancer radiotherapy. They concluded that, for long-term smokers, the absolute risks of modern radiotherapy may outweigh the benefits, yet for most nonsmokers (and ex-smokers), the benefits of radiotherapy far outweigh the risks. Hence, smoking can determine the net effect of radiotherapy on mortality, but smoking cessation substantially reduces radiotherapy risk.

Should patients be required to undergo standard chemotherapy before being eligible for novel phase I immunotherapy clinical trials?
Many Phase I oncology trials include an eligibility criterion requiring potential participants to fail standard chemotherapy. The rationale for this approach is to ensure that patients do not forgo established clinical approaches. The case described in this report has the additional feature of the consultation being requested by a research participant who wanted to challenge the ethical rationale for such an eligibility criterion.

Effect of tamsulosin on stone passage for ureteral stones: a systematic review and meta-analysis.
The researchers performed a systematic review and meta-analysis to investigate the effect of tamsulosin on stone passage in patients receiving a diagnosis of ureteral stone. They concluded that tamsulosin significantly improves stone passage in patients with larger stones, whereas the effect of tamsulosin is diminished in those with smaller stones, who are likely to pass their stone regardless of treatment.

Effectiveness of fundoplication or gastrojejunal feeding in children with neurologic impairment.
Gastroesophageal reflux (GER), aspiration, and secondary complications lead to morbidity and mortality in children with neurologic impairment (NI), dysphagia, and gastrostomy feeding. Fundoplication and gastrojejunal (GJ) feeding can reduce risk. A comparison of GJ to fundoplication using first-year postprocedure reflux-related hospitalization (RRH) rates found that in children with NI, GER, and dysphagia,:fundoplication and GJ feeding have similar RRH outcomes.

Survival gains from first-line systemic therapy in metastatic non-small cell lung cancer in the U.S., 1990-2015: progress and opportunities.
The objectives of this study were to quantify survival gains from 1990, when best supportive care only was standard, to 2015 and to estimate the impact of expanded use of new systemic therapies in clinically appropriate patients. By using simulation modeling to quantify metastatic non-small cell lung cancer survival gains from 1990-2015, the researchers estimated that the one-year survival proportion and mean per-patient survival increased by 14.1 percent and 4.2 months, respectively.

Inference and sample size calculation for clinical trials with incomplete observations of paired binary outcomes.
The researchers investigated the estimation of intervention effect and sample size determination for experiments where subjects are supposed to contribute paired binary outcomes with some incomplete observations. They theoretically prove that if incomplete data are evenly distributed between the pre-intervention and post-intervention periods, the proposed estimator will always be more efficient than the traditional estimator.

Evaluating metrics of responsiveness using patient-reported outcome measures in chronic rhinosinusitis.
This study compares responsiveness of patient-reported outcome measures (PROMs) used in chronic rhinosinusitis (CRS) to inform the future development of a highly responsive instrument that accurately portrays CRS patients' symptom experiences. For both medical therapy (MT) patients and those undergoing endoscopic sinus surgery after failing MT, CRS-specific PROMs are more responsive to posttreatment clinical changes than general health measures.

A method to reconstruct and apply 3D primary fluence for treatment delivery verification.
In this study, a method is reported to perform IMRT and VMAT treatment delivery verification using 3D volumetric primary beam fluences reconstructed directly from planned beam parameters and treatment delivery records. The goals of this paper are to demonstrate that 1) 3D beam fluences can be reconstructed efficiently, and 2) quality assurance (QA) based on the reconstructed 3D fluences is capable of detecting additional treatment delivery errors, particularly for VMAT plans.

Cost effectiveness and cost containment in the era of interferon-free therapies to treat hepatitis c virus genotype 1.
This study used Monte Carlo simulation to investigate budgetary impact and cost effectiveness of treatment policies for interferon-free regimens to treat hepatitis C virus (HCV) genotype 1 and to identify strategies that balance access with cost control. It found that among noncirrhotic patients, using the least costly interferon-free regimen, even if it is not single tablet or once daily, is the cost-control strategy that results in best outcomes.
