The combined data were simultaneously fit using the chelation model linked with a plutonium systemic model, which was linked to an ad hoc wound model. The proposed chelation model was used for dose assessment of the wound cases used in this study.The three principal pathways for intakes of plutonium are ingestion, inhalation, and contaminated wounds. In August 2018, a glovebox worker at Los Alamos National Laboratory (LANL) sustained a puncture from a thread of a braided steel cable contaminated with Pu. NBQX mouse The puncture produced no pain, no blood, and little or no visible mark. As a result, the potential for a contaminated wound was not immediately recognized, and a wound count was not conducted until elevated urine bioassay results were received 12 d after the incident. This paper discusses the circumstances of the incident, along with the medical response and dose assessment, and a discussion of the risks and benefits of the medical interventions.The urinary excretion and wound retention data collected after a Pu-contaminated wound were analyzed using Markov Chain Monte Carlo (MCMC) to obtain the posterior distribution of the intakes and doses. An empirical approach was used to model the effects of medical treatments (chelation and excision) on the reduction of doses. It was calculated that DTPA enhanced the urinary excretion, on average, by a factor of 17. The empirical analysis also allowed calculation of the efficacies of the medical treatments-excision and chelation averted approximately 76% and 5.5%, respectively, of the doses that would have been if there were no medical treatment. All bioassay data are provided in the appendix for independent analysis and to facilitate the compartmental modeling approaches being developed by the health physics community.
To characterize changes in opioid, gabapentin, and pregabalin utilization patterns and cost trends between 2008 and 2018 in a Louisiana workers’ compensation claims population and explore the role of gabapentinoids as alternative analgesics during the opioid epidemic.
Filled prescriptions for gabapentinoids and opioids were studied for 11 years in a cohort of 18,737 claimants.
The proportion of claimants prescribed gabapentin increased 2-fold (8.9% to 18.9%) and average drug cost per claimant decreased 22% ($612 to $480). The proportion of claimants prescribed pregabalin decreased approximately 80% (11.7% to 2.5%) and average drug cost per claim increased 224% ($911 to $2952). Proportion of claimants prescribed opioids decreased 20% (80% to 64.2%) and average drug cost per claim decreased 46% ($691 to $371).
Utilization increased substantially for gabapentin and decreased for pregabalin and opioids.

Evidence suggests that shiftwork results in adverse occupational health outcomes. This paper contributes to the literature by estimating the separate health effects of night and irregular shiftwork on a longitudinal panel of US workers.
Data from a 20-year panel of worker surveys from the 1979 National Longitudinal Survey of Youth were used to predict self-reported health limitations related to night and irregular shiftwork using a series of random effects logit models.
Separate and combined specifications of shiftwork as night and irregular effort significantly increase the odds of health limitations compared with working a regular daytime schedule, with more pronounced effects for irregular work (odds ratio [OR] = 1.09 to 1.52) over night shift (OR = 1.03 to 1.14).
The results suggest that both night and irregular shiftwork may have important negative implications on occupational health, with the deleterious effects particularly pronounced for irregularly scheduled work effort.

Tolvaptan (TVP) is an effective treatment for patients with cirrhotic ascites; however, studies have indicated that a sufficient effect is difficult to obtain in patients with hepatocellular carcinoma (HCC). This study evaluates the efficacy of TVP in patients with HCC with refractory ascites.
We retrospectively enrolled 32 patients with liver cirrhosis and refractory ascites [mean age 74 years (range, 47-86 years), men 78.1% (25/32)]. All patients had HCC and were treated with TVP at our hospital. A TVP responder was defined as a patient who experienced decrease in body weight by ≥1.5 kg within 1 week of treatment. Univariate and multivariate analyses were performed to evaluate clinical and laboratory predictive factors of TVP response.
The TVP response rate was 46.9% (15/32 patients) after 1 week of treatment. HCC treatment (transcatheter arterial chemoembolization and/or radiofrequency ablation) was administered to 11/15 (73.3%) responders. In the multivariate analysis, the reduction of urine osmolality was higher in responders than nonresponders (202 mOsm/l vs. 65 mOsm/l, P = 0.040), and the tumor stage (P = 0.043) was worse in nonresponders. Multivariate Cox proportional hazards regression analysis indicated a significantly better prognosis among responders than among nonresponders (P < 0.01).
The HCC tumor stage and the reduction in urine osmolality can predict the efficacy of TVP in patients with refractory ascites complicated with HCC. TVP may allow therapeutic intervention for HCC and improve prognosis, even in patients with Child-Pugh class C.

Deep venous thrombosis (DVT) has been increasingly recognized complication in these patients and is associated with increased morbidity and mortality. However, the factors associated with development of DVT in patients with COVID-19 have not been elucidated due to the novelty of the virus. We performed a meta-analysis of published studies comparing laboratory results in COVID-19 patients with and without DVT with the aim of identifying risk factors. We searched major databases for studies evaluating DVT in COVID-positive patients and performed a meta-analysis of baseline laboratory markers associated with development of DVT. A total of six studies with 678 patients were included in the pooled analyses. Of the 678 patients, 205 of patients had a DVT. Patients diagnosed with DVT were more likely to be older [mean difference 4.59 years, 95% confidence interval (CI) 1.25-7.92], and needing admission to ICU (relative risk 1.96, 95% CI 1.
