Alzheimer's disease (AD) is the most common cause of dementia in elderly people and is among the greatest healthcare challenges of the 21st century. However, the etiology and pathogenesis of AD remain poorly understood, and no curative treatments are available to slow down or stop the degenerative effects of AD. As a high-throughput approach, metabolomics is gaining significant attention in AD research, because it has a powerful potential to discover novel biomarkers, unravel new therapeutic targets for AD, and identify perturbed metabolic pathways involved in AD progression...

Micronutrient deficiencies contribute to many age-related disorders. One group at particular risk of micronutrient deficiencies is the elderly. Many elderly, such as the frail and those living in institutions, rely on ready meals of variable, often poor, nutritional quality for a significant part of their daily nutritional needs. New policies are needed to ensure that micronutrients (vitamins and minerals) and phytochemicals of known nutritional value are retained during the manufacture of ready meals. This together with increased awareness of the importance of micronutrients for health, and simple, clear labelling of the micronutrient content of ready meals would help in the choice of healthier products...

REVIEW
Joachim Denner
The chronic shortage of human transplants to treat tissue and organ failure has led to the development of xenotransplantation, the transplantation of cells, tissues and organs from another species to human recipients. For a number of reasons, pigs are best suited as donor animals. Successful, routine xenotransplantation would have an enormous impact on the health of the human population, including the young, who sometimes require a replacement organ or islet cells, but especially the elderly, who more often suffer the consequences of organ failure...

BACKGROUND: At the time of diagnosis, most patients with acute myeloid leukemia are older than 65 years of age. Treatment of this group of patients is challenging because they become less tolerant to aggressive chemotherapy with increasing age. Less than one-third of elderly patients are considered eligible for intensive treatment; nevertheless, the survival analysis for this population remains poor. Due to numerous comorbidities and an overall deteriorating condition, most elderly patients with acute myeloid leukemia receive only palliative or best supportive care, which are associated with a high mortality rate...

Purpose: Merkel cell carcinoma (MCC) is a highly aggressive neuroendocrine tumor of the skin. Merkel cell polyomavirus (MCPyV) plays an oncogenic role in the majority of MCCs. Detection of MCPyV in MCCs has diagnostic utility and prognostic potential. We investigated whether RNAscope, an RNA in situ hybridization (ISH) assay for detection of RNA transcripts in tissues, is useful for MCPyV detection. <p>Experimental Design: We applied an RNAscope probe targeting MCPyV T antigen transcripts on tissue microarrays (TMAs) and whole tissue sections encompassing 87 MCCs from 75 patients, 14 carcinomas of other types, and benign tissues...

Rheumatoid arthritis (RA) is an autoimmune disorder distinguished by synovial inflammation followed by destruction of joint. The pathogenesis of arthritis involves immune imbalance of the endogenous system. Causative factors include immune imbalance, oxidative stress, genetics, and environment. Continued effort has been made to treat RA via chemical, enzymatic, genetic, and hormonal approaches. RA has been reported more in the aged and in women. Arthritis necessitates lifelong administration of drugs to maintain quality of life...

To produce coordinated manual actions within specific space and time, their relationship must be properly dealt with in a sensorimotor system. This study examined how such a coordination system might be impaired in normal aging and in Parkinson's disease (PD). Using a tablet device, young participants, elderly participants, and patients with PD were tested for concurrent production of distance and duration as well as single production of distance or duration alone. Results were analyzed in relation to deficiency of presynaptic dopamine transporter (DaT) in the striatum...

An elderly man presented to the ED from a nursing care facility after transient loss of consciousness. Three weeks previously, the patient had been diagnosed with a high-grade pancreatic neuroendocrine tumor (NET) with metastases to the liver after being hospitalized for weakness. A chest radiograph at that time had revealed a right upper lobe mass that was presumed to represent a metastatic lesion (Fig 1); CT of the chest demonstrated similar findings (Fig 2). The patient had recovered consciousness on arrival to the ED and was diagnosed clinically as having had a syncopal episode from dehydration due to poor intake...

Myelodysplastic syndromes (MDS) are clonal neoplasms of aging that are associated with BM failure, related cytopenias, fatigue, susceptibility to infections, bruising, bleeding, a shortened lifespan, and a propensity for leukemic transformation. Most frail, elderly patients are not candidates for curative allogeneic BM transplantations and instead receive expectant management, supportive blood transfusions, or empirical, nontargeted therapy. It has been known for some time that MDS arises in an abnormal BM immune environment; however, connections have only recently been established with recurring MDS-associated mutations...

Spatiotemporal analysis is an important tool to monitor changes of tuberculosis (TB) epidemiology, identify high-risk regions and guide resource allocation. However, there are limited data on the contributing factors of TB incidence. This study aimed to investigate the spatiotemporal pattern of TB incidence and its associated factors in mainland China during 2005-2013. Global Moran's I test, Getis-Ord Gi index and heat maps were used to examine the spatial clustering and seasonal patterns. Generalized Linear Mixed Model was applied to identify factors associated with TB incidence...

Multipotent mesenchymal stromal cells are considered as a perspective tool in cell therapy and regenerative medicine. Unfortunately, autologous cell therapy does not always provide positive outcomes in elder donors, perhaps as a result of the alterations of stem cell compartments. The mechanisms of stem and progenitor cell senescence and the factors engaged are investigated intensively. In present paper, we elucidated the effects of tissue-related O2 on morphology, functions, and transcriptomic profile of adipose tissue-derived stromal cells (ASCs) in replicative senescence in vitro model...

Staphylococcal food poisoning is the result of consumption of food contaminated with staphylococcal enterotoxins (SEs) produced by Staphylococcus aureus. To date, 23 SEs and SE-like enterotoxins (SEls) have been described in the literature. They are divided into classical SEs (SEA-SEE) and new SE/SEls (SEG-SElX). Some have proved to be foodborne-inducible, but others remain unidentified. In May 2016, at an elderly group home in Osaka city, Japan, an outbreak from foodborne pathogens occurred among lunch party participants...

Sex differences in the prevalence of affective disorders might be attributable to different sex hormone milieu. The effects of short-term sex hormone deficiency on behavior, especially on anxiety have been studied in numerous animal experiments, mainly on young adult rats and mice. However, sex differences in aged animals and the effects of long-term hypogonadism are understudied. The aim of our study was to analyze sex differences in anxiety-like behavior in aged rats and to prove whether they can be attributed to endogenous sex hormone production in males...

Respiratory syncytial virus (RSV) is a major cause of respiratory infections in infants and the elderly, leading to more deaths than influenza each year, but there is no antiviral or efficacious vaccine currently available. Here we examine the role in infection of the host mitochondrial protein p32 (HABP/gC1qR/C1qbp) for the first time. RSV replication as well as infectious virus production was significantly reduced by p32 siRNA knockdown, consistent with an important role for p32 in RSV infection. p32 showed distinct mitochondrial localization throughout RSV infection, but immunostaining and high resolution confocal imaging for p32 as well as MitoTracker Red and cytochrome c, revealed clear changes in mitochondrial organization in RSV infection, with perinuclear mitochondrial compaction and asymmetric distribution at 8 and 18 h post-infection, respectively...

The aim was to determine whether neuromuscular electrical stimulation (NMES) affects skeletal muscle regeneration through a reduction of oxidative status in satellite cells of healthy elderly subjects. Satellite cells from the Vastus lateralis skeletal muscle of 12 healthy elderly subjects before and after 8 weeks of NMES were allowed to proliferate to provide myogenic populations of adult stem cells (myogenic precursor cells; MPCs). These MPCs were then investigated in terms of their proliferation, their basal cytoplasmic free Ca(2+) concentrations, and their expression of myogenic regulatory factors (PAX3, PAX7, MYF5, MYOD, MYOG) and microRNAs (miR-1, miR-133a/b, miR-206)...
