The influence of specific weather types on stroke occurrence: an analysis of 23,000 patients from Augsburg, Germany.

For the first time, the relationships between large-scale weather types and local stroke events in the urban area of Augsburg, Germany are analyzed. Over 23,000 stroke cases (2006 - 2020) were standardized to account for long-term trends and seasonality. Using ERA5 reanalysis data, a composite analysis identified stroke-related atmospheric variables, while seasonal weather types were classified via the neural network algorithm of self-organizing maps.

New Insights into Weather and Stroke: Influences of Specific Air Masses and Temperature Changes on Stroke Incidence.

Background/objectives: Meteorological factors seem to influence stroke incidence, however, the complex association between weather and stroke remains unclear. Possible explanations from the literature do not categorize into subdivisions of ischemic strokes, only have small patient numbers, or refer to a selection of isolated weather elements without investigating weather changes and more.

Method: In this exploratory trial, almost 18,000 stroke cases from a single stroke center in Southern Germany were analyzed from 2006 to 2015 and classified into the main subgroups of strokes and subdivisions of ischemic stroke etiologies applying the Trial of Org 10172 in Acute Stroke Treatment classification.

Safety aspects of 36 months of administration of long-acting intramuscular testosterone undecanoate for treatment of female-to-male transgender individuals.

Design: Testosterone treatment is essential for the induction and maintenance of virilization of female-to-male (FTM) transsexuals. Aim To test the safety of a novel testosterone preparation for this purpose.

Methods: Parenteral long-acting testosterone undecanoate (TU) was administered to 17 FTM transsexuals over 36 months.

Long-acting intramuscular testosterone undecanoate for treatment of female-to-male transgender individuals.

Aim: Testosterone treatment is essential for the induction and maintenance of virilization of female-to-male transsexuals. This study tested the suitability of a novel testosterone preparation for this purpose.

Methods: Parenteral long-acting testosterone undecanoate (TU) was administered to 12 female-to-male transsexuals.

The usefulness of a thyrotropin-releasing hormone stimulation test in subfertile female patients.

Background: The thyrotropin-releasing hormone (TRH) stimulation test is widely used as a screening procedure in subfertile patients to identify subclinical hypothyroidism. However, its usefulness in daily clinical practice has not been proven, despite more than 30 years of use.

Material And Methods: We analyzed data from a cohort of 371 consecutive female subfertility patients, who were screened with an intravenous TRH test when they came for the first evaluation.

[Significance of urban climatologic expert assessment for urban planning and development].

Aspects of urban climatology relevant to urban planning are given in respect of quality of the atmosphere and urban climate modification. This paper deals with the spatial evaluation of emission and incidence of air pollution, local conditions of air flow and diffusion, climatic effects of different surface types and conditions of urban ventilation.
