The endocrine system plays a major role in the regulation of several biological activity and in the ageing process. Evolutionary conservation of GH/IGF-I/insulin pathway from worms to mice and similarities in this system between mice and humans raised expectations that downregulated activity of the GH/IGF-I/insulin pathway could be beneficial for the extension of human life span. Centenarians represent the best example of successful ageing having reached the very extremes of the human life span, escaping and delaying the occurrence of several fatal age-related diseases, such as cancer and cardiovascular diseases...

Although a link between probiotic intervention and reduction in atopic disease has been documented, no consistent associations with microbiota has yet been established. Here we have conducted an extensive analysis of the microbiota from more than 250 mother child pairs from a probiotic intervention cohort, where we previously have shown 40 % reduction in atopic dermatitis. Within the probiotic intervention group at the age of 10 days we found that the atopic children had a deviating microbiota (p = 0.028, BH-FDR corrected Kruskal Wallis) with high levels (> 10 %) of a bacterium related to Bifidobacterium dentium (p=0...

BACKGROUND: Regular physical activity has important health benefits for children with type 1 diabetes mellitus (T1DM), yet children and their parents face barriers to participation such as lack of self-efficacy or concerns around hypoglycaemia. Multimedia interventions are useful for educating children about their health and demonstrate potential to improve children's health-related self-efficacy, but few paediatric clinics offer web-based resources as part of routine care. The Steps to Active Kids with Diabetes (STAK-D) programme is an online intervention grounded in psychological theory (social cognitive theory) and informed by extensive preliminary research...

Ruosha Li, Limin Peng
An important goal of censored quantile regression is to provide reliable predictions of survival quantiles, which are often reported in practice to offer robust and comprehensive biomedical summaries. However, formal methods for evaluating and comparing working quantile regression models in terms of their performance in predicting survival quantiles have been lacking, especially when the working models are subject to model mis-specification. In this article, we proposes a sensible and rigorous framework to fill in this gap...

BACKGROUND: Guidelines have provided positive recommendations for pulmonary rehabilitation after exacerbations of chronic obstructive pulmonary disease (COPD), but recent studies indicate that postexacerbation rehabilitation may not always be effective in patients with unstable COPD. OBJECTIVES: To assess effects of pulmonary rehabilitation after COPD exacerbations on hospital admissions (primary outcome) and other patient-important outcomes (mortality, health-related quality of life (HRQL) and exercise capacity)...

Eriel Martínez, Javier Campos-Gómez
The oxygenation of unsaturated fatty acids by dioxygenases occurs in all kingdoms of life and produces physiologically important lipids called oxylipins. The biological roles of oxylipins have been extensively studied in animals, plants, algae and fungi, but remain largely unidentified in prokaryotes. The bacterium Pseudomonas aeruginosa displays a diol synthase activity that transforms several monounsaturated fatty acids into mono- and di-hydroxylated derivatives. Here we show that oxylipins derived from this activity inhibit flagellum-driven motility and upregulate type IV pilus-dependent twitching motility of P...

Leuconostoc mesenteroides is a member of lactic acid bacteria (LAB) with wide applications in the food and medical industries. Species in the genus Leuconostoc are catalase-negative and generally regarded as facultative anaerobic or aerotolerant organisms. Despite their extensive use in industry, certain issues concerning the aerobic life of L. mesenteroides, e.g., the mechanism involved in the tolerance to oxygen, remain to be addressed. In this manuscript, a survival strategy employed by L. mesenteroides BD3749 in response to oxidative stress was elucidated...

BACKGROUND: Total Knee Arthroplasty (TKA) is a common surgical treatment for severe knee Osteoarthritis (OA), which generally improves pain, physical function, quality of life and possibly fall risk. Fall risk increases for older adults with severe knee OA; however it has not been studied extensively whether this parameter is improved after TKA. OBJECTIVE: To investigate: a) the history and frequency of falls, including mechanism or causes of falls, injuries sustained from falls reported, activity during falling and location of falls and, b) the factors affecting falls, a year after TKA in elderly patients with severe knee OA...

INTRODUCTION: Anorexia Nervosa affects up to 1% of the population and can present with binge/purge episodes. A paucity of literature exists regarding small bowel and colonic ischaemia relating to this common condition. We report our own experience and management of a patient with anorexia nervosa binge/purge subtype with small bowel and colon ischaemia and review existing cases in the literature. PRESENTATION OF CASE: A 32year old female self-presented to the emergency department complaining of abdominal pain, abdominal distension and vomiting on a background history of binge/purge subtype eating disorder, following consumption of a large amount of carbohydrates...

OBJECTIVE: To present the diagnostic workup in an extremely low birth weight infant patient with signs of both sepsis and hemophagocytosis. PARTICIPANTS: A preterm infant presented with clinical and laboratory signs of early-onset sepsis including hepatosplenomegaly, thrombocytopenia, direct hyperbilirubinemia, and elevated liver enzymes. METHODS: Despite extensive septic workup, no underlying infection was detected. Additional hyperferritinemia and other elevated inflammatory parameters raised the suspicion of a primary or secondary hemophagocytic lymphohistiocytosis (HLH)...

Migration is an important life-history event in a wide range of taxa, yet many migrations are influenced by anthropogenic change. Although migration dynamics are extensively studied, the potential effects of environmental contaminants on migratory physiology are poorly understood. In this study we show that an anxiolytic drug in water can promote downward migratory behaviour of Atlantic salmon (Salmo salar) in both laboratory setting and in a natural river tributary. Exposing salmon smolt to a dilute concentration of a GABAA receptor agonist (oxazepam) increased migration intensity compared with untreated smolt...

J Kircher
Implantation of reverse shoulder endoprostheses is becoming more popular for elderly patients besides the well-established standard anatomic endoprostheses. The reasons for this are the increased life expectancy, age-dependent degeneration of the rotator cuff leading to cuff tear arthropathy, posttraumatic disability after failed osteosynthesis and primary reverse fracture arthroplasty. Stemless implants are more frequently used for primary osteoarthritis with the bone quality being the limiting factor. Modern implant systems allow the stepwise extension from bone preserving primary implants to modular and convertible revision implants that allow a partial exchange of components...

Candida albicans behaviors are affected by pH, an important environmental variable. Filamentous growth is a pH-responsive behavior, where alkaline conditions favor hyphal growth and acid conditions favor growth as yeast. We employed filamentous growth as a tool to study the impact of pH on the hyphal growth regulator Cyr1, and we report that downregulation of cyclic AMP (cAMP) signaling by acidic pH contributes to the inhibition of hyphal growth in minimal medium with GlcNAc. Ras1 and Cyr1 are generally required for efficient hyphal growth, and the effects of low pH on Ras1 proteolysis and GTP binding are consistent with diminished cAMP output...

The number of elderly people is growing at an unprecedented rate and this increase of the aging population is expected to have a direct impact on the incidence of age-related diseases and healthcare-associated costs. Thus, it is imperative that new tools are developed to fight and slow age-related diseases. Regenerative medicine is a promising strategy for the maintenance of health and function late in life; however, stem cell-based therapies face several challenges including rejection and tumor transformation...

Small intestinal bleeding in Crohn's disease patients with noncirrhotic portal hypertension and partial portal and superior mesenteric vein thrombosis is a life-threatening event. Here, a case is reported in which treatment with azathioprine may have resulted in nodular regenerative hyperplasia, portal hypertension and portal vein thrombosis. The 56-year-old patient with Crohn's disease developed nodular regenerative hyperplasia under treatment with azathioprine. He was admitted with severe bleeding. Gastroscopy showed small esophageal varices without bleeding stigmata...

The kidney allocation system that took effect on December 4, 2014 represents a significant improvement over the prior approach. It seeks to improve outcomes by longevity matching - pairing kidneys expected to function the longest with recipients expected to live the longest. It addresses the biological barriers faced by highly sensitized patients in an evidence based fashion and it begins to introduce the concept of medical need into kidney allocation by crediting time from the starting dialysis to a patient's waiting time...

Ageing is driven by a loss of transcriptional and protein homeostasis and is the key risk factor for multiple chronic diseases. Interventions that attenuate or reverse systemic dysfunction associated with age therefore have the potential to reduce overall disease risk in the elderly. Precursor mRNA (pre-mRNA) splicing is a fundamental link between gene expression and the proteome, and deregulation of the splicing machinery is linked to several age-related chronic illnesses. However, the role of splicing homeostasis in healthy ageing remains unclear...

Antibacterial resistance is a pressing global health challenge that necessitates the development of new therapeutic agents. Phenylthiazole antibacterial agents have been extensively studied, by our group, as a potential novel class of antibiotics to circumvent the scourge of antibacterial resistance. Previously, the phenylthiazole lead compound 1 was shown to possess potent activity against clinical isolates of methicillin- and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA). The promising activity of this novel class of antibiotics is hampered by their short half-life due to rapid hepatic metabolism...
