Association of Opioid Use Disorder With 2016 Presidential Voting Patterns: Cross-sectional Study in New York State at Census Tract Level

BackgroundOpioid overdose-related deaths have increased dramatically in recent years. Combating the opioid epidemic requires better understanding of the epidemiology of opioid poisoning (OP) and opioid use disorder (OUD).ObjectiveWe aimed to discover geospatial patterns in nonmedical opioid use and its correlations with demographic features related to despair and economic hardship, most notably the US presidential voting patterns in 2016 at census tract level in New York State.MethodsThis cross-sectional analysis used data from New York Statewide Planning and Research Cooperative System claims data and the presidential voting results of 2016 in New York State from the Harvard Election Data Archive. We included 63,958 patients who had at least one OUD diagnosis between 2010 and 2016 and 36,004 patients with at least one OP diagnosis between 2012 and 2016. Geospatial mappings were created to compare areas of New York in OUD rates and presidential voting patterns. A multiple regression model examines the extent that certain factors explain OUD rate variation.ResultsSeveral areas shared similar patterns of OUD rates and Republican vote: census tracts in western New York, central New York, and Suffolk County. The correlation between OUD rates and the Republican vote was .38 (P<.001). The regression model with census tract level of demographic and socioeconomic factors explains 30% of the variance in OUD rates, with disability and Republican vote as the most significant predictors.ConclusionsAt the census tract level, OUD rates were positively correlated with Republican support in the 2016 presidential election, disability, unemployment, and unmarried status. Socioeconomic and demographic despair-related features explain a large portion of the association between the Republican vote and OUD. Together, these findings underscore the importance of socioeconomic interventions in combating the opioid epidemic.     

乳酸及降钙素原对一氧化碳中毒后迟发性脑病的预测价值

目的探讨检测血乳酸、降钙素原和联合检测对急性一氧化碳中毒后迟发性脑病(DEACMP)的预测价值。 方法随机抽取我院在急诊科收住院的ACMP患者70例,随访3个月,以其中发生DEACMP患者10例为DEACMP组,其余60例为非DEACMP组,随机抽取同期笔者医院40例健康体检者为对照组。对患者立即行动脉血Lac和血清PCT检测,并计算Lac和PCT诊断DEACMP的灵敏度、特异度。 结果DEACMP组血Lac和PCT检测值均明显高于非DEACMP和对照组,差异有统计学意义(采用秩和检验,P<0.05);检测异常率亦明显高于非DEACMP组及对照组,差异有统计学意义(采用χ²检验,P<0.05)。Lac和PCT升高预测DEACMP的敏感度均为90.0% ,特异度分别为50.0%和65.0% ,准确性分别为55.7%和68.6%。联合检测时若其中1个指标为阳性时即预测DEACMP发病,则联合检测的敏感度为100.0%,特异度为41.7%,阳性预测值为21.7%,阴性预测值为100.0%,准确性为71.4%。 结论DEACMP患者早期动脉血Lac和PCT均明显升高,PCT诊断价值优于Lac,联合检测较单项指标检测对DEACMP发病预测价值更理想。

Macroscopic hematuria in wasp sting patients: a retrospective study

BackgroundMacroscopic hematuria after wasp sting has been reported in Asia to occur before acute kidney injury (AKI), and is often used by clinicians as a sign indicating the need for intensive care and blood purification therapy. However, there is no study on the clinical characteristics and prognosis of this symptom.MethodsThe clinical data of 363 patients with wasp sting admitted to Suining Central Hospital from January 2016 to December 2018 were retrospectively analyzed. At admission, the poisoning severity score (PSS) was used as the criterion for severity classification. According to the presence of macroscopic hematuria, the patients were divided into macroscopic hematuria and non-macroscopic hematuria group.ResultsOf the 363 wasp sting patients, 219 were male and 144 were female, with a mean age of 55.9 ± 16.3 years. Fifty-one (14%) had macroscopic hematuria, 39 (10.7%) had AKI, 105 (28.9%) had rhabdomyolysis, 61 (16.8%) had hemolysis, 45 (12.4%) went on to received hemodialysis, and 14 (3.9%) died. The incidence of AKI in macroscopic hematuria group was 70.6%, and oliguric renal failure accounted for 72.2%. Patients with macroscopic hematuria had significantly higher PSS (2.2 ± 0.5 vs. 1.1 ± 0.3, p < .001).ConclusionMacroscopic hematuria can be regarded as a surrogate marker of deteriorating clinical outcome following wasp stings. In wasp sting patients with symptoms of macroscopic hematuria or serum LDH higher than 463.5 u/L upon admission, the risk of AKI increases significantly, therefore hemodialysis should be considered. The PSS is helpful in early assessment of the severity of wasp sting patients.
