Purpose: The aim of this study was to evaluate the success and survival rates of extraoral implants for the fixation of facial prostheses in three anatomical regions.
Materials And Methods: Subjects were consecutive patients with facial defects who underwent implant placement by the same surgeon in the orbital, nasal, and auricular regions between 2003 and 2012. After a minimum of 4 months of osseointegration, prostheses were anchored to the implants, and the patients were monitored for 11 to 111 months. Success rate, implant survival time, and occurrence of previous radiotherapy were evaluated. Rate of implant survival was estimated as a function of the anatomical region of the three groups (orbital, nasal, or auricular), and confidence intervals were calculated using Kaplan-Meier analysis with α = .05.
Results: In the 68 patients' 138 fixed implants, 48 showed defects in the orbital, 9 in the nasal, and 11 in the auricular region. The success rates and survival times were 95.9% and 8.6 years for the orbital, 92.9% and 2.8 years for the nasal, and 92% and 9.0 years for the auricular region, respectively. The success rate of implants in previously irradiated regions was 90.3% for the orbital and 100% for the auricular region. None of the patients was irradiated in the nasal region.
Conclusion: No significant differences in implant success or survival were observed with regard to anatomical region or previous irradiation.

Early vs. Delayed Switching from Controlled to Assisted Ventilation: A Target Trial Emulation.

Radbound Univeristy Medical Center, Nijmegen, Netherlands;
Rationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone towards ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied.
Objectives: Our objective was to determine whether a strategy of early as compared to delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality.
Nowcasting to Monitor Real-Time Mpox Trends During the 2022 Outbreak in New York City: Evaluation Using Reportable Disease Data Stratified by Race or Ethnicity.

Background: Applying nowcasting methods to partially accrued reportable disease data can help policymakers interpret recent epidemic trends despite data lags and quickly identify and remediate health inequities. During the 2022 mpox outbreak in New York City, we applied Nowcasting by Bayesian Smoothing (NobBS) to estimate recent cases, citywide and stratified by race or ethnicity (Black or African American, Hispanic or Latino, and White). However, in real time, it was unclear if the estimates were accurate.

Phenotypic plasticity in body growth enables organisms to cope with unpredictable paucities in resource availability. Growth traits influence survival and reproductive success, and thereby, population persistence, and early-life resource availability may govern lifetime patterns in growth, reproductive success, and survival. The influence of early-life environment is decidedly consequential for indeterminately growing ectotherms, which rely on available resources and ambient temperatures to maximize fitness throughout life.

Acute pulmonary embolism (PE) is a significant cause of cardiac arrests, with subsequent high mortality worldwide. Early recognition of acute PE allows earlier diagnosis, stabilization, and risk stratification, which are crucial in deciding the most adequate treatment option. However, diagnosis is sometimes difficult due to nonspecific clinical presentation.

The green sea turtle () is the only sea turtle species that breeds in China, and the largest remaining nesting grounds for green sea turtles in Chinese waters is found on the Qilianyu atoll of the Xisha Islands. Nesting site selection is particularly important for egg survival, and understanding the microhabitat characteristics of green sea turtle nesting sites is crucial for delineating priority conservation areas for nesting grounds. In this study, we aimed to examine the role of several microhabitat ecological factors in the selection of nesting sites and the success of nesting.
