Bicuspid aortic valve is the most common congenital cardiac defect in adults, and symptom typically develops in adulthood. In the majority of cases, bicuspid aortic valve disease progress with ages and surgical aortic valve replacement is performed with excellent operative outcomes. However, with the relatively slow progression of disease, surgical aortic valve replacement is required in elderly patients but the surgical risk often deemed extremely high due to old age and multiple comorbidities. Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for intermediate- and high-risk patients with symptomatic severe aortic valve stenosis (AS)...

Extraskeletal myxoid chondrosarcoma is a rare subtype of sarcoma that affects the soft tissue and bones in middle-aged and elderly adults. Its diagnosis can be challenging, with the differential diagnoses including a wide variety of mesenchymal tumors. The line of differentiation of extraskeletal myxoid chondrosarcoma has been controversial, but recent evidence suggests a neuroendocrine phenotype. INSM1 is a zinc-finger transcription factor that plays a pivotal role in neuroendocrine differentiation, and has been proposed as a promising immunohistochemical marker of neuroendocrine carcinoma...

INTRODUCTION: There is an increasing number of elderly in society and some of them may have an abdominal aortic aneurysm (AAA). The prevalence of AAA in octo-and non-agenarians indicates that this number could be substantial. The question is; is there an age limit for repair? This complex question incorporates ethical, political, economic and medical aspects. To answer part of this question a review of the outcome of elective and emergent AAA repair in those over 80 was done. EVIDENCE ACQUSITION: A litterature research was done in the Pubmed and Embase databases between 2007 and 2017 for either emergent and/or elective repair of AAA in individuals older than 80 years of age...

BACKGROUND: Racial/ethnic, gender, and age disparities in access to renal transplantation among end-stage renal disease (ESRD) patients have been well documented, but few studies have explored health care staff attitudes towards these inequalities. Staff perceptions can influence patient care and outcomes, and identifying staff perceptions on disparities could aid in the development of potential interventions to address these health inequities. The objective of this study was to investigate dialysis staff (n = 509), primarily social workers and nurse managers, perceptions of renal transplant disparities in the Southeastern United States...

OBJECTIVES: Due to the demographic change, the global prevalence of dementia will continually rise. Barriers to diagnosis and care are still high. But timely diagnosis is associated with valuable benefits and can promote timely and optimal management. Receiving an early diagnosis is especially in rural areas a problem due to the limited access to assessments. Therefore, the aim of our scoping review is to investigate different interventions targeted at rural living elderly to screen and diagnose cognitive decline and dementia...

OBJECTIVES/HYPOTHESIS: Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine neoplasm of the skin. Growing evidence supports the benefit of postoperative adjuvant radiation therapy (RT) for locoregional control, but whether it improves overall survival (OS) has been debated. Our objective was to compare the OS of MCC patients who received postoperative RT with those who received surgery alone. STUDY DESIGN: Retrospective case series. METHODS: Cases of MCC between 2001 and 2016 at the University of California, Los Angeles Health System were reviewed...

BACKGROUND: Sweden has a policy of supporting older people to live a normal life at home for as long as possible. Therefore, it is often the oldest, most frail people who move into nursing homes. Nursing home staff are expected to meet the existential needs of the residents, yet conversations about death and dying tend to cause emotional strain. This study explores organizational readiness to implement palliative care based on evidence-based guidelines in nursing homes in Sweden. The aim was to identify barriers and facilitators to implementing evidence-based palliative care in nursing homes...

OBJECTIVES: Low concentrations of serum 25-hydroxyvitamin D [25(OH)D] have been postulated to associate with an increased prevalence of depression. As there are a limited number of publications on this issue, we examined the association between serum 25(OH)D and depression in a general middle-aged or older population. DESIGN: A population-based cross-sectional study. SETTING AND PARTICIPANTS: A total of 1602 men and women from the population-based Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) in Eastern Finland, aged 53-73 y in 1998-2001, were analysed...

INTRODUCTION: Malnutrition is a frequent condition in the elderly especially in hospitals and in nursing homes, and even among the free-living elders the prevalence is not negligible (5-10%). Awareness towards malnutrition is still limited. The lack of time for nutritional assessment by the overcommitted healthcare personnel, including the general practitioners (GPs), may represent one possible explanation for limited recognition of malnutrition. Therefore, a self-administered instrument could be useful in raising alert on the GPs and allow early detection of malnutrition and early care provision...

PURPOSE: Watershed areas (WSAs) of the brain are most susceptible to acute hypoperfusion due to their peripheral location between vascular territories. Additionally, chronic WSA-related vascular processes underlie cognitive decline especially in patients with cerebral hemodynamic compromise. Despite of high relevance for both clinical diagnostics and research, individual in vivo WSA definition is fairly limited to date. Thus, this study proposes a standardized segmentation approach to delineate individual WSAs by use of time-to-peak (TTP) maps and investigates spatial variability of individual WSAs...

Hairy cell leukemia variant (HCLv) is a chronic lymphoproliferative disorder classified as a provisional entity in the 2016 WHO Classification of Lymphoid Tumors. HCLv is characterized by unfavorable prognosis, low complete remission rates and limited disease control following classical hairy cell leukemia-based regimens. In this study, we report 3 cases of elderly patients with treatment-naive, TP53 un-mutated HCLv, who were effectively treated with four cycles of bendamustine plus rituximab. The regimen was completed in all the patients with acceptable toxicity...
