Hospital case volume is associated with improved survival for patients with metastatic melanoma.
This study investigated the influence of hospital case volume on malignant melanoma survival and treatment utilization. The researchers discovered that for patients diagnosed with metastatic melanoma, being treated in a high-volume hospital was associated with an improvement in survival and lower utilization of chemotherapy, immunotherapy, surgery, and radiation therapy.

Incidence of hepaticojejunostomy stricture after hepaticojejunostomy.
The authors aimed to determine the timing, incidence, and management of stricture after biliary-enteric anastomosis. They found that younger age was associated with a decreased likelihood of stricture formation and that the presence of an endostent predicted stricture formation. They concluded that biliary-enteric anastomotic strictures occur with significant frequency after a biliary-enteric anastomosis, and that while many patients are managed nonoperatively, stricture diagnosis remains burdensome.

Pulmonary rehabilitation utilization in older adults with chronic obstructive pulmonary disease, 2003 to 2012.
The authors assessed the trends in pulmonary rehabilitation (PR) utilization and factors associated with its use in older adults with chronic obstructive pulmonary disease (COPD). They concluded that utilization of PR during the study period increased only 1.1% in these Medicare beneficiaries with COPD and remained low.

Prior cancer does not adversely affect survival in locally advanced lung cancer: a national SEER-Medicare analysis.
Researchers identified patients > 65 years of age diagnosed 1992-2009 with locally advanced lung cancer in the Surveillance, Epidemiology, and End Results-Medicare linked dataset. They found that, for patients with locally advanced lung cancer, prior cancer does not adversely impact clinical outcomes. Patients with locally advanced lung cancer and a history of prior cancer should not be excluded from clinical trials.

Association of reduced eGFR and albuminuria with serious fall injuries among older adults.
The researchers studied adverse outcomes in patients on dialysis as a result of falls. They found that among participants with CKD, cumulative 1-year mortality rates among patients with a serious fall and age-matched controls were 21.0% and 5.5%, respectively, and noted that elevated ACR but not lower eGFR was associated with serious fall injuries. They concluded that evaluation for fall risk factors and fall prevention strategies should be considered for older adults with elevated ACR.

Huang ES
Management of diabetes mellitus in older people with comorbidities.
Guidelines recommend that physicians individualize the intensity of glucose control and treatments on the basis of the prognosis (for example, three tiers based on comorbidities and functional impairments). Very few studies have attempted to study these concepts in clinical practice. To better meet the treatment needs of older patients with diabetes and comorbidities, more research is needed to determine the risks and benefits of intensifying, maintaining, or de-intensifying treatments in this population.

Androgen therapy and rehospitalization in older men with testosterone deficiency.
This study assessed whether the receipt of androgen therapy is associated with a reduced 30-day rehospitalization rate among older men with testosterone deficiency. It concluded that androgen therapy may reduce the risk of rehospitalization in older men with testosterone deficiency.

Elevated serum osmolality and total water deficit indicate impaired hydration status in residents of long-term care facilities regardless of low or high body mass index.
The researchers assessed hydration status and the adequacy of total water intake, and further determined relationships between hydration status, total water intake, and body mass index (BMI) in long-term care residents. They found that dehydration and inadequate total water intake is prevalent in long-term care residents across all BMI categories. They recommended that the type of liquid beverages, type of ONS, and type of between-meal snacks are factors that could be targeted for nutrition interventions designed to prevent or reverse dehydration.

Trends in follow-up of patients presenting to the emergency department with symptomatic cholelithiasis.
To better understand underuse of cholecystectomy, the researchers examined physician follow-up patterns after emergency department (ED) visits for symptomatic gallstones. They found that fewer than half of patients were evaluated by a surgeon after an initial ED visit for symptomatic gallstones. Patients who did not have physician follow-up were most likely to require emergent cholecystectomy, suggesting inappropriate ED discharge and highlighting the need for timely follow-up.

Assessment of home-time after acute ischemic stroke in Medicare beneficiaries.
The researchers evaluated home-time as a patient-centered outcome in Medicare beneficiaries with ischemic stroke in comparison with modified Rankin Scale (mRS) score at 90 days and at 1 year post event. They concluded that in a population of older patients with ischemic stroke, home-time was readily available from administrative data and associated with mRS at 90 days and 1 year.

Trends in end-of-life cancer care in the Medicare program.
The researchers sought to examine contemporary trends in end-of-life cancer care and geographic variation of end-of-life care aggressiveness among Medicare beneficiaries. They found that the proportion of beneficiaries receiving at least one potentially aggressive end-of-life intervention increased in repeated hospitalization, repeated ED visits, ICU admissions, and late hospice enrollment but declined in in-hospital death. End-of-life chemotherapy use did not change significantly over time. They concluded that despite growing focus on providing appropriate end-of-life care, there has not been an improvement in aggressive end-of-life cancer care in the Medicare program.

Relative contributions of complications and failure to rescue on mortality in older patients undergoing pancreatectomy.
This study evaluated the relative contribution of overall postoperative complications and failure to rescue rates on the observed increased mortality in older patients undergoing pancreatic resection at specialized centers. In experienced hands, the rates of complications after pancreatectomy in patients 80 years or older compared to patients younger than 80 years were similar. However, when complications occurred, older patients were more likely to die.

Effectiveness and safety of aldosterone antagonist therapy use among older patients with reduced ejection fraction after acute myocardial infarction.
The purpose of this paper is to describe how aldosterone antagonist treatment is used among older myocardial infarction (MI) patients in routine practice. They found that aldosterone antagonist use was not associated with lower mortality except in symptomatic HF patients, and risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists, as was risk of acute renal failure compared with patients not prescribed aldosterone antagonists. They concluded that these results underscore the importance of close post-discharge monitoring of this patient population.

Impact of hematopoietic growth factors on blood transfusion needs, incidence of neutropenia, and overall survival among elderly advanced ovarian cancer patients treated with chemotherapy.
The researchers sought to determine the effectiveness of erythropoietin-stimulating agent (ESA) and granulocyte colony-stimulating factor (CSF) in reducing blood transfusion needs and neutropenia incidence in community-dwelling elderly ovarian cancer patients. They found that erythropoietin-stimulating agents were effective in reducing blood transfusion need. Granulocyte colony-stimulating factors were effective in lowering neutropenia incidence and also were associated with improved survival in elderly ovarian cancer patients.

Trends in receipt and timing of multimodality therapy in early-stage pancreatic cancer.
The researchers described treatment patterns and time trends with regard to age and treatment center in the receipt of multimodality therapy for early-stage pancreatic cancer. They concluded that despite increased use of multimodality therapy, it remains underutilized in all patients and especially in older patients. Receipt of multimodality therapy and neoadjuvant therapy is highly dependent on treatment at NCI-designated cancer centers.
