Occupational risks of COVID-19: a case-cohort study using health insurance claims data in Germany.

Background: Studies on occupation and COVID-19 infection that cover a range of occupational groups and adjust for important confounders are lacking. This study aimed to estimate occupational risks of hospitalization with COVID-19 by taking into account sociodemographic factors and previous comorbidities.

Methods: We applied a case-cohort design using workers insured with one of Germany's largest statutory health insurers as a data source for occupational and demographical information as well as for information on comorbidities.

Radiation-Detoxified Form of Endotoxin Effectively Activates Th Responses and Attenuates Ragweed-Induced Th-Type Airway Inflammation in Mice.

Urbanization with reduced microbial exposure is associated with an increased burden of asthma and atopic symptoms. Conversely, environmental exposure to endotoxins in childhood can protect against the development of allergies. Our study aimed to investigate whether the renaturation of the indoor environment with aerosolized radiation-detoxified lipopolysaccharide (RD-LPS) has a preventative effect against the development of ragweed-induced Th-type airway inflammation.

Emotions and worries during 1.5 years of the COVID-19 pandemic - how adults with and without mental health conditions coped with the crisis.

Background: During the COVID 19 pandemic, there were social restrictions with severe mental stress for a long time. Most studies on mental health consequences of the pandemic focused primarily on the beginning of the pandemic. The present study on families of patients or study participants of a child and adolescent psychiatry aimed to examine long-term profiles of emotions and worries in adults with and without mental health condition (mhc) during the first 1.

The Burden of Disease in Germany at the National and Regional Level.

Background: .Summary measures such as disability-adjusted life years (DALY) are becoming increasingly important for the standardized assessment of the burden of disease due to death and disability. The BURDEN 2020 pilot project was designed as an independent burden-of-disease study for Germany, which was based on nationwide data, but which also yielded regional estimates.

[Utilizing Routine Health Insurance Data for Calculation of Disease Frequencies in the Project BURDEN 2020].

Objective: The concept of disease burden enables a comprehensive analysis of the health status of a population. Key indicators are years of life lost due to mortality (YLL) and morbidity (years lived with disability, YLD), summarised in the DALY indicator (disability adjusted life years). These indicators are suitable for planning prevention, health care or provision of health services.

N-Nitrosodimethylamine-Contaminated Valsartan and the Risk of Cancer—A Longitudinal Cohort Study Based on German Health Insurance Data.

Background: N-Nitrosodimethylamine (NDMA), classified as a probable human carcinogen, has been found as a contaminant in the antihypertensive drug valsartan. Potentially carcinogenic effects associated with the consumption of NDMAcontaminated valsartan have not yet been analyzed in large-scale cohort studies. We therefore carried out the study reported here to explore the association between NDMA-contaminated valsartan and the risk of cancer.

Fructose, glucose and fat interrelationships with metabolic pathway regulation and effects on the gut microbiota.

The purpose of this 30-day feeding study was to elucidate the changes, correlations, and mechanisms caused by the replacement of the starch content of the AIN-93G diet (St) with glucose (G), fructose (F) or lard (L) in body and organ weights, metabolic changes and caecal microbiota composition in rats (Wistar, SPF). The body weight gain of rats on the F diet was 12% less (P = 0.12) than in the St group.

Wireless Readout of Multiple SAW Temperature Sensors.

It has since long been known that surface acoustic wave (SAW) devices, resonators as well as delay lines, can be used as passive wireless sensors for physical quantities, like temperature and pressure, as well as gas sensors or identification-tags (ID-tags). The sensors are robust, work passively without a battery, can be applied at high temperatures, and provide a high resolution. Nevertheless, if the devices are used wirelessly in an industrial environment, several constraints have to be taken into account, especially when more than one quantity or device needs to be measured at the same time.

A LN/Si-Based SAW Pressure Sensor.

Surface Acoustic Wave (SAW) sensors are small, passive and wireless devices. We present here the latest results obtained in a project aimed at developing a SAW-based implantable pressure sensor, equipped with a well-defined, 30 μm-thick, 4.7 mm-in-diameter, Lithium Niobate (LN) membrane.

BURDEN 2020-Burden of disease in Germany at the national and regional level.

Background: Evidence-based policy measures need non-interest-guided information about the health status of a population and the diseases that affect the population the most. In such cases, a national burden of disease study can provide reliable insights at the regional level.

Aim: This article presents the potential of the BURDEN 2020 project and its expected outcome for Germany at the national and regional level.

Real-World Massage Therapy Produces Meaningful Effectiveness Signal for Primary Care Patients with Chronic Low Back Pain: Results of a Repeated Measures Cohort Study.

Objective: While efficacy of massage and other nonpharmacological treatments for chronic low back pain is established, stakeholders have called for pragmatic studies of effectiveness in "real-world" primary health care. The Kentucky Pain Research and Outcomes Study evaluated massage impact on pain, disability, and health-related quality of life for primary care patients with chronic low back pain. We report effectiveness and feasibility results, and make comparisons with established minimal clinically important differences.

Ion exchanger in the brain: Quantitative analysis of perineuronally fixed anionic binding sites suggests diffusion barriers with ion sorting properties.

Perineuronal nets (PNs) are a specialized form of brain extracellular matrix, consisting of negatively charged glycosaminoglycans, glycoproteins and proteoglycans in the direct microenvironment of neurons. Still, locally immobilized charges in the tissue have not been accessible so far to direct observations and quantifications. Here, we present a new approach to visualize and quantify fixed charge-densities on brain slices using a focused proton-beam microprobe in combination with ionic metallic probes.

A brief overview of the history of veterinary field services in South Africa.

The historical evolution of veterinary services in South Africa is closely linked to the colonial history of the past and the eventual political formation of the Union of South Africa in 1910, as well as the establishment of a fully democratic South Africa in 1994. The majority of the early pioneering veterinarians had close links to military activities and were originally mostly of British origin. The appointment of the first colonial chief veterinary officers occurred in the late 1800s.

Comparison of endotoxin levels in cow's milk samples derived from farms and shops.

The observations on the protective effect of bacterial endotoxin in farm-derived cow's milk on childhood asthma and allergy are contradictory. The aim of this study was to determine the endotoxin levels in 'farm-derived whole raw' and 'processed shop' sources of cow's milk, and to test how the temperature and storing conditions might alter their endotoxin concentrations. Milk was collected from farms and shops.

The immunomodulatory role of bile acids.

Enzymatic oxidation of cholesterol generates numerous distinct bile acids which function both as detergents that facilitate the digestion and absorption of dietary lipids and as hormones that activate five distinct receptors. Activation of these receptors alters gene expression in multiple tissues, leading to changes not only in bile acid metabolism but also in glucose homeostasis, lipid and lipoprotein metabolism, energy expenditure, intestinal motility, bacterial growth, inflammation, and in the liver-gut axis. This review focuses on the present knowledge regarding the physiologic and pathologic role of bile acids and their immunomodulatory role, with particular attention to bacterial lipopolysaccharides (endotoxins) and bile acid and immunological disorders.

Tenascin-R promotes assembly of the extracellular matrix of perineuronal nets via clustering of aggrecan.

Perineuronal nets (PNs) in the brains of tenascin-R-deficient (tn-r(-/-)) mice develop in temporal concordance with those of wild-type (tn-r(+/+)) mice. However, the histological appearance of PNs is abnormal in adult tn-r(-/-) mice. Here, we investigated whether similar defects are also seen in dissociated and organotypic cultures from hippocampus and forebrain of tn-r(-/-) mice and whether the structure of PNs could be normalized.

Experimental and theoretical investigations of some useful langasite cuts for high-temperature SAW applications.

Passive high-temperature sensors are a most promising area of use for SAW devices. Langasite (La3Ga5SiO14; LGS) has been identified as promising piezoelectric material to meet high-temperature SAW challenges. Because it is necessary to know the material behavior for an accurate device design, the frequency¿temperature behavior of Rayleigh SAW (R-SAW) and shear-horizontal SAW (SH-SAW) LGS cuts is investigated on delay line and resonator test structures up to 700°C by RF characterization.

Perineuronal and perisynaptic extracellular matrix in the human spinal cord.

Extracellular matrix (ECM) forms an active interface around neurons of the central nervous system (CNS). Whilst the components, chemical heterogeneity and cellular recruitment of this intercellular assembly in various parts of the brain have been discussed in detail, the spinal cord received limited attention in this context. This is in sharp contrast to its clinical relevance since the overall role of ECM especially that of its chondroitin sulphate-based proteoglycan components (CSPGs) was repeatedly addressed in neuropathology, regeneration, CNS repair and therapy models.

Veterinary service missions and good governance.

The rationale for the existence of official Veterinary Services (VS) has seldom been under such intensive public scrutiny as over the past two decades when the world has been confronted with outbreaks of major animal diseases that have posed a potential threat not only to human health but also to animal health and national food security. The mere existence of VS is not enough. The mission statement of the VS can no longer be cast in stone but needs to adapt and be amended continually to cope with new demands.

Nutrition intervention to decrease symptoms in patients with advanced heart failure.

For a majority of patients with advanced heart failure, there is a need for complementary, non-pharmacologic interventions that could be easily implemented by health care providers to provide palliative care. Three major pathologic pathways underlying heart failure symptoms have been identified: fluid overload, inflammation, and oxidative stress. Prior research has demonstrated that three nutrients-sodium, omega-3 fatty acids, and lycopene-can alter these pathologic pathways.

Unique features of extracellular matrix in the mouse medial nucleus of trapezoid body--implications for physiological functions.

The medial nucleus of the trapezoid body (MNTB) is a vital structure of sound localization circuits in the auditory brainstem. Each principal cell of MNTB is contacted by a very large presynaptic glutamatergic terminal, the calyx of Held. The MNTB principal cells themselves are surrounded by extracellular matrix components forming prominent perineuronal nets (PNs).

Aggrecan: Beyond cartilage and into the brain.

Aggrecan is well-studied in cartilage but its expression and function in the central nervous system has only recently begun to be appreciated. Aggrecan plays an important role in the organization of the neural extracellular space by binding and organizing hyaluronan to the cell surface through interactions with link protein and tenascins forming a large aggregated quaternary complex. While all members of the lectican family to which aggrecan belongs are thought to mediate similar roles in organizing the neural matrix, aggrecan is unique in that it is the only family member found almost exclusively in an enigmatic matrix substructure called the perineuronal net.
