However, the abnormal increase in craniocaudal Young's modulus did not compensate for the degradation of whole bone mechanical properties due to the bone loss. In conclusion, it was clarified that changes in the material quality, which are hidden in bone mass evaluation, occur with estrogen deficiency-induced osteoporosis and IBN treatment. Here, IBN was shown to be a beneficial drug that suppresses abnormal changes in bone mechanical integrity caused by estrogen deficiency at both the whole bone and material levels.Decisions with considerable medical and ethical implications are made in emergency departments every day. Despite time pressure and high workloads, they have to be arrived at in an expert manner in all dimensions. For immediate ethical decisions, structuring the decision-making process in the form of standard procedures can be helpful, provided that they are trained and practiced in an interdisciplinary and interprofessional manner. The support for ad hoc ethical decisions presented here recommends an "ethical team time out" for the evaluation of treatment choices, in a framework where the patient's will and medical indication are examined and completed in a structured manner. Further experts (ideally, an ad hoc clinical ethics consultation) should be consulted if the treatment measure is of questionable medical benefit and/or of questionable patient consent.
Increasing requirements for documentation, cross-sectoral communication and quality management are leading to increased organizational effort in emergency medical services (EMS). On the one hand, the use of digital information systems in prehospital settings can help to support emergency physicians and paramedics in these tasks and on the other hand, it opens new treatment options such as telemedical care for patients. This work attempts to provide acomprehensive picture of the current use of digital systems for ambulance services in Germany. To do so, the study investigated how widespread various information and communication systems currently are at local EMS stations and ambulances, how they are used by emergency personnel, how they are assessed by users and what challenges currently exist for further expansion and greater acceptance of the users.
The cross-sectional study was conducted as anationwide, exploratory online survey among emergency physicians and paramedic professionals in July and August 2development process could contribute to increasing functionality and user acceptance.
Although information technology systems in German EMS are no longer in their infancy, there is still a long way to go before prehospital emergency care can be considered as extensively and adequately digitalized. A more holistic perspective and networked implementation of all systems and processes involved in emergency response operations can help improve and further spread digital solutions for prehospital emergency care. Incorporating field experience into the development process could contribute to increasing functionality and user acceptance.
The cytology of lymph nodes is acost-effective method with ashort turnaround time and low risk to patients that delivers valuable information on the cause of the lymphadenopathies.
To discuss the value of lymph node cytology in the diagnosis of lymph node swellings.
Analysis of the causes of the controversially discussed aspects of lymph node cytology. Presentation of the diagnostic groups of lymph node cytology according to the Sydney system.
The technical aspects of lymph node sampling during fine needle biopsy, as well as the subsequent preparation of the correctly fixed direct smears and the triage of the sample for the auxiliary studies, may pose asignificant challenge for some puncturers. The whole spectrum of modern pathologic auxiliary studies can be applied to correctly triaged cytologic samples. The diagnoses of fine needle biopsies of the lymph nodes can be divided into five groups according to the recently proposed Sydney reporting system insufficient/non-diagnostic, benign, atypical, suspicious, and malignant. Further details concerning the diagnosis as well as recommendations on how to proceed are additionally included in cytologic reports.
The improvement of lymph node sampling as well as the technical aspects of the sample handling, including the application of auxiliary studies, considerably increase the diagnostic value of fine needle biopsy of the lymph nodes. Wide implementation of the usage of the diagnostic groups for reporting fine needle biopsies of the lymph nodes can standardize reporting and improve communication with other clinical specialists.

Incomplete reperfusion after mechanical thrombectomy (MT) is associated with a poor outcome. Rescue therapy would potentially benefit some patients with an expanded treatment in cerebral ischemia score (eTICI)2b50/2b67 reperfusion but also harbors increased risks. The relative benefits of eTICI2c/3 over eTICI2b50/67 in clinically important subpopulations were analyzed.
Retrospective analysis of our institutional database for all patients with occlusion of the intracranial internal carotid artery (ICA) or the M1/M2 segment undergoing MT and final reperfusion of ≥eTICI2b50 (903patients). The heterogeneity in subgroups of different time metrics, age, National Institutes of Health Stroke Scale (NIHSS), number of retrieval attempts, Alberta Stroke Programme Early CT Score (ASPECTS) and site of occlusion using interaction terms (p
) was analyzed.
The presence of eTICI2c/3 was associated with better outcomes in most subgroups. Time metrics showed no interaction of eTICI2c/3 over eTICI2b50/2b67 and clinical outcomes (onset to reperfusion p
= 0.77, puncture to reperfusion p
= 0.65, onset to puncture p
= 0.63). An eTICI2c/3 had less consistent association with mRS ≤2 in older patients (>82years, p
= 0.038) and patients with either lower NIHSS (≤9) or very high NIHSS (>19, p
= 0.01). Regarding occlusion sites, the beneficial effect of eTICI2c/3 was absent for occlusions in the M2 segments (aOR 0.73, 95% confidence interval [CI] 0.33-1.59, p
= 0.018).
Beneficial effect of eTICI2c/3 over eTICI2b50/2b67 only decreased in older patients, M2-occlusions and patients with either low or very high NIHSS. Improving eTICI2b50/2b67 to eTICI2c/3 in those subgroups may be more often futile.

Intravenous thrombolysis and mechanical thrombectomy (MT) are standard of care in patients with acute ischemic stroke due to large vessel occlusion. Data on MT in patients with intracranial hemorrhage prior to intervention is limited to anecdotal reports, as these patients were excluded from thrombectomy trials.
We analyzed patients from an observational multicenter cohort with acute ischemic stroke and endovascular treatment, the German Stroke Registry-Endovascular Treatment trial, with intracranial hemorrhage before MT. Baseline characteristics, procedural parameters and functional outcome at 90days were analyzed and compared to apropensity score matched cohort.
Out of 6635patients, we identified 32patients (0.5%) with acute ischemic stroke due to large vessel occlusion and preinterventional intracranial hemorrhage who underwent MT. Risk factors of intracranial hemorrhage were head trauma, oral anticoagulation and intravenous thrombolysis. Overall mortality was high (50%) but among patients with apremorbid modified Rankin scale (mRS) of 0-2 (n = 15), good clinical outcome (mRS 0-2) at 90days was achieved in 40% of patients. Periprocedural and outcome results did not differ between patients with and without preinterventional intracranial hemorrhage.
Preinterventional intracranial hemorrhage in acute ischemic stroke patients with large vessel occlusion is rare. The use of MT is technically feasible and asubstantial number of patients achieve good clinical outcome, indicating that MT should not be withheld in patients with preinterventional intracranial hemorrhage.

However, for a visual fixation suppression task, it remains unknown if the pattern of coordinated head and eye movement is influenced differently by passive or active head movements. We used a suppression head impulse paradigm (SHIMP), where the subject's goal was to maintain gaze stabilized on a visual target that moved with the head during rapid impulsive head movements, to evaluate gaze fixation performance in three conditions (1) passive-unpredictable where the examiner applied impulsive head yaw rotations with random timing and direction, (2) passive-predictable where the direction of head rotation was announced and then the examiner repeatedly applied impulses in the same direction, and (3) active where the test subject self-generated their head movements. Thirteen young healthy adults performed all three conditions to assess the percentage of early saccades that initiated the gaze shift toward the final visual target position and the latency of first saccades. Early saccades were defined as those occurring within the duration of the head impulse. Results showed that active head impulses generated the greatest percentage of early saccades, followed by predictable and unpredictable. Among the two passive conditions, predictability shortened the first saccade onset latencies. Active condition onset latencies were shorter than in either of the passive conditions, showing a consistent head-leads-eye pattern defining a specific behavioral pattern that could vary across patient groups leading to insights into central neural mechanisms that control eye-head coordination.
