The implementation of measures for the prevention and treatment of PUs is insufficient in nursing homes in eastern China. Further, this study raised the issue of the lack of measures to prevent the development of PUs at home.The aim of the present work was to evaluate MTX treatment (0.1, 1 and 10 μg mL-1) in vitro in order to characterize its effects on cell proliferation alterations in cell cycle of HaCaT keratinocytes and wound healing in a Skh1 mice treated with MTX (low doses 30 mg kg-1, high doses 200 mg kg-1 and repeated doses at 1.5 mg kg-1). We analyzed the cytotoxic effect of methotrexate by a resazurin assay. The effects in the proliferation, cell cycle and apoptosis of HaCaT cells were analyzed by flow cytometry. The effects of MTX on wound healing in vivo were also analyzed. A trend toward reduction in the resazurin assay was found (p > 0.05). Reduced proliferation was also identified in a clonogenic assay and a CFSE assay (p less then 0.05) due to the MTX treatment. A reduction in the G2/M and S phases was observed accompanied by apoptosis induction with increased sub G0 phase and annexin V FITC staining. Effect of MTX was evidenced in vivo on the wound closure process after day 10 (p less then 0.05) with alterations in tissue architecture and remodeling. There is a marked effect of MTX on wound healing in vivo in Skh1 mice with implications for long-term therapy and surgical interventions.

Our study compared sensitivity, specificity, and accuracy of whole-body diffusion-weighted imaging (WB-DWI) using a b-value of 2000 s/mm

with that of the commonly used b-value of 800 s/mm

for depiction of active tumor sites in patients with plasma cell diseases. We introduced an ultrahigh b-value to reduce interfering signals from benign and post-therapeutic inactive lesions by suppressing T2-shine-through effects.

The prospective single-center study included patients when they went through a whole-body MRI (WB-MRI) staging or response evaluation procedure. The apparent diffusion coefficient (ADC) and morphologic appearance served as reference for classifying focal lesions on WB-DWI as vital or post-therapeutic. Additionally, we compared our classification with patients' serological markers of disease activity.

One hundred participants (65 ± 10 years, 58 men) underwent WB-DWI between June and October 2019. The detection rate of vital focal lesions was similar for both b-values with a sensitivity of 0.99 using b = 800 s/mm

and 0.98 using b = 2000 s/mm

. By contrast, specificity and accuracy were 0.09 and 0.71 when using a b-value of 800 s/mm

, and 0.96 and 0.98 when using a b-value of 2000 s/mm

, respectively. The difference in specificity and accuracy was statistically significant (p < 0.001).

Using a b-value of 2000 s/mm

significantly improved the specificity of lesion detection with WB-DWI as compared to the commonly used b-value of 800 s/mm

. read more The high b-value significantly reduced signal intensities of post-therapeutic or benign lesions and provided a significantly more accurate representation of active tumor load.

Using a b-value of 2000 s/mm2 significantly improved the specificity of lesion detection with WB-DWI as compared to the commonly used b-value of 800 s/mm2. The high b-value significantly reduced signal intensities of post-therapeutic or benign lesions and provided a significantly more accurate representation of active tumor load.

Use of nicotine vaping products (NVPs) to replace smoking is often influenced by perceived harmfulness of these products relative to smoking. This study aimed to identify factors that conjointly influenced NVP relative harm perception among smokers and ex-smokers.

Data (n = 11,838) from adult smokers and ex-smokers (quit < 2 years) who participated in the 2016 ITC 4 Country Smoking and Vaping Surveys in Australia, Canada, England and the US were analyzed. Decision tree models were used to classify respondents into those who perceived vaping as less harmful than smoking ("correct" perception) versus otherwise ("incorrect" perception) based on their socio-demographic, smoking and vaping related variables.

Decision tree analysis identified nicotine replacement therapy (NRT) harmfulness perceptions relative to smoking, perceived vaping portrayal in the media and other sources as positive, negative or balanced, recency of seeking online vaping information, and age as the key variables that interacted conjoint factors can serve as useful markers for identifying subgroups more vulnerable to misperception about NVP relative harmfulness to benefit from corrective intervention.

Research has established a strong and positive correlation between substance use and intimate partner violence due to a complex interplay of individual, situational, and contextual factors. This study seeks to further explore this relationship in the context of the recent opioid crisis in which millions of Americans have been diagnosed with an opioid use disorder. Specifically, we analyze how opioid prescriptions relate to intimate partner violence within and between counties over time throughout the rise of the opioid crisis.

This study employs an integrated dataset that merges crime data from the Federal Bureau of Investigation, demographic data from the American Community Survey, and prescription opioid pill counts from the Drug Enforcement Administration to study the relationship between opioid pills prescribed per person and levels of intimate partner violence arrests from 2006-2012. Fixed-effects and mixed-effects techniques are both used.

Increases in opioid pill distribution volume within-counties over time are related to increases in intimate partner violence arrest volume (p ≤ .001). Additionally, counties which have higher amounts of opioid pills in circulation tend to experience higher levels of arrests for intimate partner violence than counties with fewer pills (p ≤ .001).

Policymakers who are dealing with the effects of the opioid crisis should consider the relationship between opioids and intimate partner violence when attempting to address either of these issues. Based on the results of this study, addressing opioid dependence and mitigating the extent of the crisis may also reduce intimate partner violence.
