[Skin cancer screening in the aging population in Saxony-Anhalt : Utilization, facilitating, and hindering factors].

Background: Statutory skin cancer screening (gHKS) can counteract severe courses of various types of skin cancer. The example of malignant melanoma shows that screening is important for older adults in view of the average age of onset of this disease: 62 (women) and 68 years (men). For Saxony-Anhalt (ST), as a state particularly affected by demographic change, little gHKS data are available regarding its usage.

[Ultrasound-guided ablation techniques for thyroid lesions].

Ultrasound-guided ablation techniques have been increasingly introduced into routine treatment of thyroid lesions as a complement to existing surgical therapies and radioiodine treatment. In cystic or predominantly cystic lesions instillation therapy (ethanol/polidocanol ablation) has yielded good results. Novel thermal ablation techniques, including radiofrequency ablation (RFA), microwave ablation (MWA), laser ablation (LA) and high intensity focused ultrasound (HIFU), induce irreversible cellular effects by locally applying temperatures ≥ 60 °C to the targeted thyroid region.

The effect of ketamine on affective modulation of the startle reflex and its resting-state brain correlates.

Ketamine is a rapid-acting antidepressant that also influences neural reactivity to affective stimuli. However, the effect of ketamine on behavioral affective reactivity is yet to be elucidated. The affect-modulated startle reflex paradigm (AMSR) allows examining the valence-specific aspects of behavioral affective reactivity.

The Association between Physical Activity and Anxiety in Aging: A Comparative Analysis.

(1) Background: As the worldwide aging population is growing, there is a need to embrace the role of physical activity in the anxiety of older people. Objectives: To analyze anxiety in older people practitioners and non-practitioners of physical activity; (2) Methods: ample composed of 690 older people of both genders, unselected volunteers, residing in Brazil, present (as participants or observers) in selected street races in the state of Rio de Janeiro, Brazil, between 30 October 2019, and 12 March 2020. An instrument composed of the sociodemographic questionnaire and questions from the Beck Anxiety Inventory, BAI, and the Physical Activity Inventory for older people, Baecke-Old.

Amplitude modulation of acoustic waves in accelerating flows quantified using acoustic black and white hole analogues.

We investigate the amplitude modulation of acoustic waves in accelerating flows, a problem that is still not fully understood, but essential to many technical applications, ranging from medical imaging to acoustic remote sensing. The proposed modeling framework is based on a convective form of the Kuznetsov equation, which incorporates the background flow field and is solved numerically by a finite-difference method. Using acoustic black and white hole analogues as model systems, we identify a modulation of the wave amplitude which is shown to be driven by the divergence/convergence of the acoustic wave characteristics in an accelerating/decelerating flow, and which is distinct from the convective amplification accompanying an acoustic emitter moving at a constant velocity.

[Ready for school? An analysis of the developmental screening used as part of the school entrance examination in Germany].

The School Entrance Examination (SEE) provides important information about the educational needs of pre-school children and for health reporting. The SEE should reflect the latest scientific knowledge and generate high-quality data. To do this, it must meet scientific quality criteria and be continuously evaluated and further developed.

European Achondroplasia Forum guiding principles for the detection and management of foramen magnum stenosis.

Foramen magnum stenosis is a serious, and potentially life-threatening complication of achondroplasia. The foramen magnum is smaller in infants with achondroplasia, compared with the general population, and both restricted growth in the first 2 years and premature closure of skull plate synchondroses can contribute to narrowing. Narrowing of the foramen magnum can lead to compression of the brainstem and spinal cord, and result in sleep apnoea and sudden death.

Concept for the Real-Time Monitoring of Molecular Configurations during Manipulation with a Scanning Probe Microscope.

A bold vision in nanofabrication is the assembly of functional molecular structures using a scanning probe microscope (SPM). This approach requires continuous monitoring of the molecular configuration during manipulation. Until now, this has been impossible because the SPM tip cannot simultaneously act as an actuator and an imaging probe.
