OBJECTIVES: The aim of the present long-term study was to assess the incidence and mode of valve hemodynamic deterioration (VHD) of bioprosthetic aortic valves, as well as associated factors. BACKGROUND: Modern definitions of bioprosthetic valve deterioration recommend the use of echocardiography for the assessment of transprosthetic gradients and valvular regurgitation. METHODS: A total of 466 consecutive patients (mean age 73.5 ± 7.5 years, 56...

BACKGROUND: Protein-energy wasting (PEW) is a relatively prevalent problem among adult haemodialysis patients (HDP). PEW is an important determinant of morbidity and mortality in HDP, therefore it is essential for dietitians to accurately assess malnutrition (MN) in these patients. HDP appear to be more susceptible to developing MN; however, this is not well documented. Therefore this study aimed to assess the nutritional status among HDP and to establish the factors associated with MN in these patients...

In this study, we attempted to determine the epidemiology and clinical characteristics of hip fracture in the elderly. We find that elderly people with hip fracture have multiple comorbidities and suffer numerous complications. INTRODUCTION: We attempted to explore the epidemiology and clinical characteristics of hip fracture in the elderly. METHODS: One thousand five hundred thirty-nine patients aged over 65 years were included in the retrospective study. From the medical records, information was gathered about pre-fracture conditions, as well as fracture type, surgical details, laboratory indicators, postoperative complications, length of stay, outcomes, and costs of hospitalization...

Body composition changes resulting from ageing may impact older adults survival. However, its influence on mortality risk is uncertain. Currently, the best method for body composition analysis in clinical practice is dual energy X-ray absorptiometry (DXA). Nonetheless, the few studies on body composition by DXA and mortality risk in elderlies have some limitations. We investigated the association between body composition by DXA and mortality in a cohort of elderly subjects. Eight hundred and thirty nine (839) community-dwelling subjects (516 women, 323 men), ≥65 years, were assessed by questionnaire on clinical data, laboratory exams and body composition by DXA at baseline...

Hugo R Ramos, Luis E López, Walter Quiroga Castro, César Mj Serra
Cardiac troponins are pivotal in the evaluation of patients who suffer from acute chest pain, and the introduction of the High-Sensitivity Cardiac Troponins (hs-cTn) has shown that there are differences between male and female patients. Recent recommendations from experts point out that an appropriate evaluation must take into account the patients' sex, but there is no clear evidence of the implementation of this recommendation in the clinical practice, and the matter has sparked controversy. If the same cut-off value is used for both sexes, myocardial infarction in men might be overdiagnosed, especially in the elderly, who have relatively higher values, and might be underdiagnosed in most women...

In Parkinson's disease (PD) there is a selective degeneration of neuromelanin-containing neurons, especially substantia nigra dopaminergic neurons. In humans, neuromelanin accumulates with age, the latter being the main risk factor for PD. The contribution of neuromelanin to PD pathogenesis remains unknown because, unlike humans, common laboratory animals lack neuromelanin. Synthesis of peripheral melanins is mediated by tyrosinase, an enzyme also present at low levels in the brain. Here we report that overexpression of human tyrosinase in rat substantia nigra results in age-dependent production of human-like neuromelanin within nigral dopaminergic neurons, up to levels reached in elderly humans...

INTRODUCTION: Gabapentin (GBP) is an analog of γ-aminobutyric acid and was originally designed as an anticonvulsant. Because its mechanism of action is unclear, assumed to have no abuse potential, and apparent lack of toxicity, GBP is used widely off-label to treat an array of disorders, including essential tremor. CASE REPORT: We present a case of an elderly woman diagnosed with essential tremor, in which GBP was initiated. In the following day, she complained of urinary incontinence with the absence of dysuria and urgency...

Mobility impairment is common in older adults and influences negatively the quality of life. Mobility may changes rapidly following hospital discharge. The Timed Up and Go test (TUG) is often used to assess functional mobility; however, because TUG may require supervision from a trained clinician, assessments may be infrequent. &#13; Objective. In this paper, we aim at providing a method to evaluate TUG remotely from activities in free-living, enabling continuous remote mobility monitoring without expert supervision...

Osteomyelitis pubis is a rare orthopedic infection, accounting for less than 1-2 percent of all hematogenous osteomyelitis. Osteomyelitis pubis generally affects children, elderly patients who have undergone genitourinary procedures, and parenteral drug users. Interestingly, cases of acute osteomyelitis pubis have also been documented in previously young, healthy athletes. The diagnosis is often difficult to differentiate from osteitis pubis, which is a self-limiting, painful inflammatory condition affecting the symphysis pubis...

There is heterogeneity in the observed O2peak response to similar exercise training, and different exercise approaches produce variable degrees of exercise response (trainability). The aim of this study was to combine data from different laboratories to compare O2peak trainability between various volumes of interval training and Moderate Intensity Continuous Training (MICT). For interval training, volumes were classified by the duration of total interval time. High-volume High Intensity Interval Training (HIIT) included studies that had participants complete more than 15 min of high intensity efforts per session...

Adult-onset type II citrullinemia (CTLN2) is a urea cycle disease characterized by neurological and psychiatric abnormalities associated with hyperammonemia. One of the pathological features of CTLN2 is the presence of hepatocyte steatosis. The condition progresses in almost all CTLN2 patients to nonalcoholic fatty liver disease (NAFLD). We herein report a 74-year-old woman who developed CTLN2 without hepatocyte steatosis. The diagnosis was based on clinical and laboratory findings and confirmed by two liver biopsies conducted within 7 years, as well as by a DNA analysis, which demonstrated mutations in the SLC25A13 gene...

BACKGROUND: Hyponatremia is defined as a serum sodium level of less than 135 mEq/L in a patient. Although hyponatremia is not an uncommon laboratory finding, especially in the elderly, hunting for the etiology is a challenging issue for any clinician. The three first-line investigations that are required for further analysis are urine osmolality, serum osmolality, and urinary sodium levels in addition to clinical assessment of volume status. CASE PRESENTATION: A 69-year-old previously well Sinhalese man presented with lethargy, loss of appetite, vomiting, and altered behavior of 1 week's duration...
