In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips.

MMT and MMTP change over time; however, the changing directions show region-wide heterogeneity. We examined the heterogeneity of temporal changes in MMT and MMTP across multiple communities and in multiple countries.

Methods: We collected data for 66 locations from 13 countries in Central and South America to estimate location-specific temperature-mortality associations using time-series regression with distributed lag nonlinear models. We calculated the attributable deaths for cold and heat as the 2.
Article Synopsis
- The study investigates how daily rainfall characteristics—like intensity, duration, and frequency—affect mortality rates from all causes, cardiovascular issues, and respiratory problems across 34 countries from 1980 to 2020.
- It utilizes a time series analysis to evaluate the association between daily mortality and rainfall events that occur at different return periods (one, two, and five years), including the effects of extreme rainfall with a 14-day lag.
- The results indicate that extreme rainfall events (five-year return period) correlate with increased mortality rates, particularly for respiratory cases, while moderate rainfall shows protective effects, and the impact varies based on climate and vegetation.
Background: Heterogeneity in temperature-mortality relationships across locations may partly result from differences in the demographic structure of populations and their cause-specific vulnerabilities. Here we conduct the largest epidemiological study to date on the association between ambient temperature and mortality by age and cause using data from 532 cities in 33 countries.
Methods: We collected daily temperature and mortality data from each country.
