[Medication supply and polypharmacy in long-term care : An overview of possible interventions and the question of a functioning concept].

Background: Polypharmacy and the resulting problems lead to considerable consequences for those affected. There are also considerable problems with the medication management.

Objective: Which interventions and programs for optimizing the supply of medication are available for nursing homes and which implementation problems can be expected?

Material And Method: A literature search was carried out for interventional studies in nursing homes in Germany, with a focus on improving medication safety.

Effect of Thalamic versus Pallidal Deep Brain Stimulation on Head Tremor in Dystonic and Essential Tremor Patients-A Retrospective Video-Blinded Study.

Background: Head tremor is common in dystonia syndromes and difficult to treat. Deep brain stimulation (DBS) is a therapeutic option in medically-refractory cases. In most DBS-centers, the globus pallidus internus (GPi) is targeted in patients with predominant dystonia and the ventrointermediate nucleus of the thalamus (Vim) in predominant tremor.

The interplay of sensory feedback, arousal, and action tremor amplitude in essential tremor.

Essential tremor (ET) amplitude is modulated by visual feedback during target driven movements and in a grip force task. It has not been examined yet whether visual feedback exclusively modulates target force tremor amplitude or if other afferent inputs like auditory sensation has a modulatory effect on tremor amplitude as well. Also, it is unknown whether the enhanced sensory feedback causes an increase of arousal in persons with ET (p-ET).

Predictors and Pathophysiology of Axial Postural Abnormalities in Parkinsonism: A Scoping Review.

Background: Postural abnormalities involving the trunk are referred to as axial postural abnormalities and can be observed in over 20% of patients with Parkinson's disease (PD) and in atypical parkinsonism. These symptoms are highly disabling and frequently associated with back pain and a worse quality of life in PD. Despite their frequency, little is known about the pathophysiology of these symptoms and scant data are reported about their clinical predictors, making it difficult to prompt prevention strategies.

Dynamic evaluation of modeled ozone concentrations in Germany with four chemistry transport models.

Simulating the ozone variability at regional scales using chemistry transport models (CTMs) remains a challenge. We designed a multi-model intercomparison to evaluate, for the first time, four regional CTMs on a national scale for Germany. Simulations were conducted with LOTOS-EUROS, REM-CALGRID, COSMO-MUSCAT and WRF-Chem for January 1 to December 31, 2019, using prescribed emission information.

The Role of Levodopa Challenge in Predicting the Outcome of Subthalamic Deep Brain Stimulation.

Background: Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an effective and evidence-based treatment for idiopathic Parkinson's disease (iPD). A minority of patients does not sufficiently benefit from STN-DBS.

Objective: The predictive validity of the levodopa challenge for individual patients is analyzed.

Characterizing Camptocormia in Parkinson's Disease Using Muscle Ultrasonography.

Background: Camptocormia (CC) is the forward-bending of the spine of more than 30 degrees that can be found in Parkinson's disease (PD) as a disabling complication. Detection of changes in paraspinal lumbar musculature in CC is of value for choosing treatment strategies.

Objective: To investigate whether these changes can be detected using muscle ultrasonography (mUSG).

Grey matter correlates of dystonic soft signs in essential tremor.

Background: Questionable signs of dystonia are a common finding in patients with essential tremor (ET). Brain structural alterations in ET patients plus dystonic soft signs (ET + ds) in comparison to ET patients without dystonic soft signs (ET-ds) or patients with tremor associated with manifest dystonia (TAWD) have not been examined yet. Therefore, our study aims to explore alterations of brain grey matter in patients with ET + ds.

Aerosols' variability and their relationship with climatic parameters over West Africa.

Aerosols' influences on Earth's climate have been documented by several authors. This ranges from scattering and reflecting of shortwave radiation (direct effect) which is also regarded as the "Whitehouse Effect," to the ability to act as condensation nuclei (indirect effect) which results in cloud droplet formation. This broad summary of aerosol's effect on earth's climate has in turn affected some other weather variables either positively or negatively depending on people's perspectives.

Three-Dimensional Mesh Recovery from Common 2-Dimensional Pictures for Automated Assessment of Body Posture in Camptocormia.

Background: Three-dimensional (3D) human body estimation from common photographs is an evolving method in the field of computer vision. It has not yet been evaluated on postural disorders. We generated 3D models from 2-dimensional pictures of camptocormia patients to measure the bending angle of the trunk according to recommendations in the literature.

[Estimation of the risk of drug-related problems in nursing home residents : A retrospective analysis of routine data].

Background: Polypharmacy and drug-related problems are major challenges in the care and treatment of nursing home residents. Many interventional studies showed disappointing results, which lead to the question if this could also be due to the selection of the target parameters of these studies.

Material And Methods: A routine data set from six long-term care facilities was retrospectively analyzed.

Acquisition and Automated Segmentation of Inertia Sensor Data for Mobile Camptocormia Assessment.

The camptocormia angle has been established as a strong indicator for evaluating the progress of Parkinson's disease and the efficacy of therapeutical approaches. A wearable setup is proposed to measure the camptocormia angle with the perpendicular method using five inertial sensors. This study identifies suitable inertial measurement unit sensors for mobile long-term measurement.

Malnutrition and Inadequate Eating Behaviour during Hospital Stay in Geriatrics-An Explorative Analyses of NutritionDay Data in Two Hospitals.

(1) Background: Malnutrition in hospitalized patients is prevalent worldwide, but the severity of the issue is often underestimated by practitioners. The purpose of this study is to investigate the prevalence of malnutrition and inadequate eating behaviour in a geriatric sample. (2) Methods: Two hospitals participated with six wards on nutritionDay in 2017, 2018 and 2019.

Technical note: AQMEII4 Activity 1: evaluation of wet and dry deposition schemes as an integral part of regional-scale air quality models.

We present in this technical note the research protocol for phase 4 of the Air Quality Model Evaluation International Initiative (AQMEII4). This research initiative is divided into two activities, collectively having three goals: (i) to define the current state of the science with respect to representations of wet and especially dry deposition in regional models, (ii) to quantify the extent to which different dry deposition parameterizations influence retrospective air pollutant concentration and flux predictions, and (iii) to identify, through the use of a common set of detailed diagnostics, sensitivity simulations, model evaluation, and reduction of input uncertainty, the specific causes for the current range of these predictions. Activity 1 is dedicated to the diagnostic evaluation of wet and dry deposition processes in regional air quality models (described in this paper), and Activity 2 to the evaluation of dry deposition point models against ozone flux measurements at multiple towers with multiyear observations (to be described in future submissions as part of the special issue on AQMEII4).

[Malnutrition in geriatric patients: risk factor residential nursing home?].

Background: Malnutrition remains a challenging problem in hospitals, especially among geriatric patients. The background and causes are actually well known but still underestimated in clinical practice.

Aim And Methods: This study evaluated possible differences in rates of malnutrition risk and malnutrition in geriatric patients living at home and geriatric patients living in residential nursing homes.

[Weight loss and malnutrition risk in geriatric patients].

Background: Malnutrition is a major challenge in routine clinical practice and is associated with increased mortality.

Objectives: In the research project Prevention and treatment of malnutrition in geriatric patients in hospital funded by the Federal Ministry of Education and Research (BMBF), routine data were analyzed. The aim was to uncover the causes of malnutrition risks acquired in hospital.

Insufficiency of trunk extension and impaired control of muscle force in Parkinson's disease with camptocormia.

Objective: To examine the aetiology of parkinsonian camptocormia, a non-fixed pathological forward bending of the trunk, by measuring trunk muscle activation and force regulation in Parkinson patients with (PD + CC) and without (PD) camptocormia matched for disease severity, and in age- and sex-matched healthy controls (HC).

Methods: The isometric forces of trunk extension and flexion were measured in PD + CC, PD and HC. Neuromuscular efficiency (increase of extension force per increase of paravertebral muscle surface electromyography signal) and the ability to maintain a constant submaximal trunk extension force were examined.

Quantitative assessment of posture in healthy controls and patients with Parkinson's disease.

Introduction: A stooped posture is a main clinical feature of Parkinson's disease (PD). The assessment of posture is important to measure treatment effects. The aim of this study was to investigate the reliability of a standardized postural rating tool, to calculate minimal detectable change scores and to assess the role of gender and age.

Measurement of camptocormia trunk flexion using a dual-sensor measurement setup.

Assessing the flexion of the trunk of patients with camptocormia is a key factor in developing therapies for camptocormia and monitoring their success. Currently used methods to measure this camptocormia angle are based on photographs or short videos. Both methods are not able to take the ability of patients into account to compensate their symptoms for short amounts of time.

[Analysis of the effectiveness of urinary incontinence management in a geriatric rehabilitation].

Background: Urinary incontinence is a widespread health-related problem predominately occurring in older adults. The aim of the study was to evaluate the effectiveness of the management of urinary incontinence in routine care in a geriatric rehabilitation clinic.

Methods: A prospective observational study without a control group was conducted between 7 February 2018 and 7 June 2018.

The Effect of Medication and Deep Brain Stimulation on Posture in Parkinson's Disease.

Postural abnormalities are common in Parkinson's disease (PD) and increasing with disease progression. While many studies focus on balance and gait, postural alignment is only infrequently studied. The aim of the present study was to examine the immediate and long-term effects of medication and deep brain stimulation (DBS) in the subthalamic nucleus on postural alignment in PD.

Enhanced Chlorine and Bromine Atom Activation by Hydrolysis of Halogen Nitrates from Marine Aerosols at Polluted Coastal Areas.

Detailed multiphase chemistry box model studies are carried out, investigating halogen radical activation at polluted coastal areas. Simulations are performed for a nonpermanent cloud and a cloud-free scenario and reveal that ClNO photolysis and ICl photolysis are crucial for gas-phase Cl atom activation. In the cloud scenario, the integrated ClNO and ICl photolysis rates are 3.

Consensus for the measurement of the camptocormia angle in the standing patient.

Introduction: Camptocormia is characterized by a pathological forward flexion of the trunk, which is reversible when lying and worsened by standing and walking. So far there is no consensus on how to measure the angle of flexion, and studies therefore give differing results. Harmonization is needed for both research and clinical practice.
