Abstract

Introduction: South Carolina has experienced a surge in fatal overdoses, primarily fueled by opioid-involved overdose deaths. This work aims to quantify the burden of premature mortality due to fatal opioid-involved overdoses in South Carolina while documenting the contribution of synthetic opioids to excess mortality, examining substance specific geographic and demographic patterns of mortality burden, and measuring the effect of fatal opioid and synthetic opioid-involved overdoses on average lifespan. Methods: We obtained death certificates for fatalities involving opioids, cocaine, benzodiazepines, and psychostimulants (N = 3,726) in South Carolina from 2014 to 2018. Years of Potential Life Lost (YPLL) was used to examine gender, racial, and geographic disparities in mortality burden. We assessed the contribution of synthetic opioid poisoning to the overall opioid mortality burden over time and calculated the effect of fatal opioid and synthetic opioid-involved overdoses on average lifespan. Results: From 2014 to 2018, opioid-involved overdose deaths resulted in 124,451 YPLL. The average age of fatal male and female opioid-involved overdoses decreased 2.8 and 3.9 years, respectively. Synthetic opioids increasingly contributed to opioid YPLL, accounting for 22% in 2014 to 64% in 2018. Mortality burden was not shared equally between races, sexes, or rural/urban counties. The largest change occurred in black male synthetic opioid-involved deaths (2234%). Rural counties comprised 44-48% of the population adjusted YPLL despite containing 34% of the population. Conclusion: Opioid-involved overdoses account for a critical cause of mortality in South Carolina, demonstrate significant impact on YPLL and highlight mortality burden disparities in gender, race, and rural/urban settings.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
