Carina Goos, Mario Dejung, Christian J Janzen, Falk Butter, Susanne Kramer
Trypanosoma brucei is a protozoan flagellate that is transmitted by tsetse flies into the mammalian bloodstream. The parasite has a huge impact on human health both directly by causing African sleeping sickness and indirectly, by infecting domestic cattle. The biology of trypanosomes involves some highly unusual, nuclear-localised processes. These include polycistronic transcription without classical promoters initiated from regions defined by histone variants, trans-splicing of all transcripts to the exon of a spliced leader RNA, transcription of some very abundant proteins by RNA polymerase I and antigenic variation, a switch in expression of the cell surface protein variants that allows the parasite to resist the immune system of its mammalian host...

Physical activity was identified as a major determinant of longevity. Using wearable accelerometers, we evaluated energy expenditure (EE), including resting- (REE) and total-energy expenditure, (TEE), physical activity level (PAL), percentage of PAL ≥ 3 metabolic equivalent tasks (METs), number of steps, resting index (RI%) and sleeping patterns in 44 free-living nonagenarians (27 men) residing in a Sardinian village famous for its longevous population. The average REE and TEE recorded were: men 1278 ± 161 kcal/day and 957 ± 110, and women: 2286 ± 541kcal/day and 1811 ± 308 in the women, respectively...

OBJECTIVES: Measure the clinical effectiveness and cost effectiveness of using sensor data from an environmentally embedded sensor system for early illness recognition. This sensor system has demonstrated in pilot studies to detect changes in function and in chronic diseases or acute illnesses on average 10 days to 2 weeks before usual assessment methods or self-reports of illness. DESIGN: Prospective intervention study in 13 assisted living (AL) communities of 171 residents randomly assigned to intervention (n=86) or comparison group (n=85) receiving usual care...

Vector-borne trypanosomatid parasite infections in tropical and sub-tropical countries constitute a major threat to humans and livestock. Trypanosoma brucei parasites are transmitted by tsetse fly and lead to African sleeping sickness in humans and Nagana in cattle. In Latin American countries, Trypanosoma cruzi infections spread by triatomine kissing bugs lead to Chagas disease. Various species of Leishmania transmitted to humans by phlebotomine sandflies manifest in a spectrum of diseases termed Leishmaniasis...

We report the synthesis and biological evaluation of a series of 7-aryl-1,2,4-triazolo[4,3-a]pyridines with mGlu2 positive allosteric modulator (PAM) activity and affinity. Besides traditional in vitro parameters of potency and affinity, kinetic parameters kon, koff and residence time (RT) were determined. The PAMs showed various kinetic profiles; kon values ranged over two orders of magnitude, whereas RT values were within a 10-fold range. Association rate constant kon was linearly correlated to affinity. Evaluation of a short, medium and long RT compound in a label-free assay indicated a correlation between RT and functional effect...

BACKGROUND: Fibromyalgia, a potentially debilitating chronic pain syndrome of unknown etiology, may be characterized by inflammation. In this study, we investigated the relation of FMS to serum C-reactive protein (CRP) in a large population of adults (18+) and investigated the influence of other factors on this relationship, including BMI, comorbidities, as well as mood and sleep disturbance. METHODS: Participants were 52,535 Ohio Valley residents (Fibromyalgia n = 1125)...

OBJECTIVE: In times of the ubiquitous debate about doctors' working hour restrictions, it is still questionable if the physician's performance is impaired by high workload and long shifts. In this study we evaluated the impact of sleep interruption on the neurosurgical performance. METHODS: Ten medical students and ten neurosurgical residents were tested on the virtual-reality simulator NeuroTouch by performing the identical microsurgical task, well-rested (baseline test), and after sleep interruption at night (stress test)...

BACKGROUND: Traumatic fractures place a substantial burden on health-care systems worldwide. Although detailed information about incidence, distribution, and risk factors for traumatic fractures is vital for planning and prevention, in China, national data are unavailable. We aimed to do an up-to-date national survey on the population-weighted incidence of traumatic fractures in China. METHODS: The China National Fracture Study (CNFS) was a retrospective epidemiological study that recruited a nationally representative sample from eight provinces, 24 urban cities, and 24 rural counties in China using stratified random sampling and the probability proportional to size method...

Based on the secondary data analysis, this study aimed to identify quality of life and factors that affect quality of life among Korean elderly with mild cognitive impairment. Demographic characteristics, physical factors, and psychosocial factors as well as quality of life of the elderly with mild cognitive impairment were comprehensively measured. The research subjects consisted of 348 home-resident elderly and their quality of life scores were relatively high at 29.86. Their quality of life varied according to education and gender, and instrumental activities of daily living (actual, latent), somatic symptoms, sleep quality, depression, and social support affected their quality of life...

INTRODUCTION: Rapid eye movement sleep behavior disorder (RBD) is strongly associated with synucleinopathies. In 2012, we reported an increased risk of mild cognitive impairment (MCI) and Parkinson disease (PD) in cognitively normal Olmsted County, Minnesota, residents, aged 70 to 89 years with probable RBD. Here, we examine their progression to dementia and other neurodegenerative phenotypes. METHODS: Fifteen participants with RBD who were diagnosed with either MCI or PD were longitudinally followed, and their subsequent clinical courses were reviewed...

Daily rhythms of physiological and behavioral processes such as sleep and arousal are controlled by the circadian clock. The expression of the clock genes oscillate rhythmically in daily manner, and this clock oscillator resides in almost all of the cells in the body. The circadian clock entrains to diurnal environmental changes by using light and food intake as external time cues. Timing of feeding and fasting strongly affects daily rhythms in the expression of circadian clock genes and key regulators of nutrient homeostasis...

PURPOSE: The German Aerospace Center (DLR) investigated in the NORAH sleep study the association between a distinct change in nocturnal aircraft noise exposure due to the introduction of a night curfew (11:00 p.m.-5:00 a.m.) at Frankfurt Airport and short-term annoyance reactions of residents in the surrounding community. Exposure-response curves were calculated by random effects logistic regression to evaluate the aircraft noise-related parameters (1) number of overflights and (2) energy equivalent noise level LASeq for the prediction of short-term annoyance...

Obstructive sleep apnea (OSA) is an important and socially relevant problem of modern medicine, which is referred to as a most common pathological condition. The problem of OSA is especially urgent for inhabitants of high mountainous regions, as a combination of climatic, social, and cultural factors can significantly affect the course of the disease in both indigenous highlanders and people temporarily residing at high altitude. The paper reviews the current literature covering the problem of OSA at high altitude...

STUDY OBJECTIVE: Medical residents working overnight call shifts experience sleep deprivation and circadian clock disruption. This leads to deficits in sensorimotor function and increases in workplace accidents. Using quick tablet-based tasks, we investigate whether measureable executive function differences exist following a single overnight call versus routine shift, and whether factors like stress, rest and caffeine affect these measures. DESIGN: A prospective, observational, longitudinal, comparison study was conducted...

BACKGROUND: Antipsychotics form a class of drugs that should be used with caution among elderly people because of a high risk of adverse events. Despite the risks and modest effects, their use is estimated to be high, especially in nursing homes. OBJECTIVE: The aim was to explore the effects of medication reviews on antipsychotic drug use for elderly primary care patients and describe the extent of, and reasons for, the prescription of antipsychotics. METHODS: In this cross-sectional study in primary care in Skåne, Sweden, patients aged ≥75 years living in nursing homes or in their own homes with home care were included...
