Objectives To examine whether physical activity (PA) was associated with fatigue, and quantify the extent of potential mediation through depressive symptoms or physical function (PF) on the relationship between PA and fatigue in symptomatic knee osteoarthritis (KOA).Method This longitudinal study used data from the Multicenter Osteoarthritis Study (n = 484), comprising subjects aged ≥ 50 years. Baseline PA was quantified via an ankle-worn accelerometer. The outcome was fatigue, measured using a 0-10 rating scale at 2 year follow-up. Mediators included gait speed as a measure of PF and depressive symptoms at 2 year follow-up. Mediation analysis was carried out after adjustment for baseline confounders. Stratified analysis by baseline fatigue status [no/low ( less then 4) and high (≥ 4) fatigue] was performed.Results A significant direct association was found between PA and fatigue at 2 years [unstandardized coefficient (B) = -0.054; 95% confidence interval (CI) -0.107, -0.002, p = 0.041]. The PA-fatigue relationship was not mediated by gait speed (B = -0.006; 95% CI -0.018, 0.001) or depressive symptoms (B = 0.009; 95% CI 0.009, 0.028). In the subgroup with high baseline fatigue, direct associations were found between PA and fatigue (gait speed model, B = -0.107; 95% CI -0.212, -0.002, p = 0.046; depressive symptoms model B = -0.110; 95% CI -0.120, -0.020, p = 0.017); but in the no/low baseline fatigue group, no significant association was found between PA and fatigue.Conclusion In the symptomatic KOA population, higher baseline PA was directly associated with reduced fatigue 2 years later, especially in those with high baseline fatigue. However, this relationship was not mediated by depressive symptoms or PF.
The transition to adulthood may be especially difficult for those who use drugs and alcohol regularly. While research clearly links adverse childhood experiences (ACEs) with later substance use, many studies have explored only a limited range of ACEs, and have focused on the number instead of specific types of ACE.
The current study examined the role of ACEs on the likelihood of frequent marijuana and alcohol use among a community sample of emerging adults (
 = 185). This research builds on and extends previous work by focusing on a low-income sample, examining specific types of ACEs, and expanding categories to include some less studied ACEs. Logistic regression models examined the relationships between ACEs and frequent alcohol or marijuana use.
The emerging adults in the current sample experienced many ACEs in childhood, and roughly a third reported frequent (defined as using once a week or more for the past 90 days) alcohol or marijuana use. ACEs associated with both frequent marijuana and alcohobeing in foster care may be overlooked as a trauma beyond the experiences that contributed to entering care.Leukocyte cell proportion changes affect the detection of cancer-associated aberrant DNA methylation alterations in peripheral blood samples. We aimed to detect cellular DNA methylation changes in ovarian cancer (OVC) blood samples avoiding the above-mentioned cell-composition effects. Based on the within-sample relative methylation orderings (RMOs) of CpG loci in leukocyte subtypes, we developed the Ref-RMO method to detect aberrant methylation alterations from OVC blood samples. Stable CpG pairs with consistent RMOs in different leukocyte subtypes were determined, more than 99% of which retained their RMO patterns in peripheral whole blood (PWB) in independent datasets. Based on the stable CpG pairs, significantly reversed CpG pairs were detected from OVC PWB samples, which were relative to clinical information such as age, subtype, grade, stage, or CA125 level. Results showed 439 CpG loci were determined to be significant differential DNA methylations between OVC and healthy blood samples. They were mainly enriched in KEGG pathways, such as cytokine-cytokine receptor interaction, apoptosis, proteoglycans in cancer, and immune-associated Gene Ontology terms. STRING analysis showed that they tended to have functional interactions with cancer-associated genes recorded in the COSMIC database. Leukocyte cellular differential DNA methylations could be identified by the proposed RMO-based method from OVC PWB samples, which were cancer-associated aberrant signals against cell-composition effects.Basal macroautophagy/autophagy has recently been found in anucleate platelets. Platelet autophagy is involved in platelet activation and thrombus formation. However, the mechanism underlying autophagy in anucleate platelets require further clarification. Our data revealed that LC3-II formation and SQSTM1/p62 degradation were noted in H2O2-activated human platelets, which could be blocked by 3-methyladenine and bafilomycin A1, indicating that platelet activation may cause platelet autophagy. AMPK phosphorylation and MTOR dephosphorylation were also detected, and block of AMPK activity by the AMPK inhibitor dorsomorphin reversed SQSTM1 degradation and LC3-II formation. Moreover, autophagosome formation was observed through transmission electron microscopy and deconvolution microscopy. These findings suggest that platelet autophagy was induced partly through the AMPK-MTOR pathway. In addition, increased LC3-II expression occurred only in H2O2-treated Atg5f/f platelets, but not in H2O2-treated atg5-/- platelets, dized low-density lipoprotein; pAb polyclonal antibody; PC phosphatidylcholine; PCR polymerase chain reaction; PI3K phosphoinositide 3-kinase; PLS-DA partial least-squares discriminant analysis; PRP platelet-rich plasma; Q-TOF quadrupole-time of flight; RBC red blood cell; ROS reactive oxygen species; RPS6KB/p70S6K ribosomal protein S6 kinase B; SDS sodium dodecyl sulfate; S.E.M. standard error of the mean; SEM scanning electron microscopy; SGMS sphingomyelin synthase; SM sphingomyelin; SMPD/SMase sphingomyelin phosphodiesterase; SQSTM1/p62 sequestosome 1; TEM transmission electron microscopy; UGT8/CGT UDP glycosyltransferase 8; UGCG/GCS UDP-glucose ceramide glucosyltransferase; ULK1 unc-51 like autophagy activating kinase 1; UPLC ultra-performance liquid chromatography; PIK3C3/VPS34 phosphatidylinositol 3-kinase catalytic subunit type 3; PtdIns3P phosphatidylinositol-3-phosphate; WBC white blood cell; WT wild type.
To shorten the time for diagnosis of suspected colorectal cancer (CRC), a standardized colorectal cancer referral pathway (CCRP) was introduced in Sweden in September 2016. However, the effects of the CCRP are still uncertain, and CRC is also found in patients undergoing a routine colonoscopy.

To identify all CRC-cases in the Region Örebro County and to investigate
which diagnostic pathway they were diagnosed. Furthermore, to investigate the reasons for and possible effect of not being included in the CCRP for cases found
colonoscopy.

Review of medical records of patients with CRC referred to the department of surgery in the Region Örebro County in 2016-2018 (
 = 459).

In CRC-cases found through colonoscopy (
 = 347), 37.5% were diagnosed
a routine waiting list and 62.5% within the CCRP. No difference in tumor stage or tumor grade was found between the two groups. The non-CCRP showed a longer time to diagnosis than the CCRP group (21.5 days, IQR 7-43 vs. 13 days, IQR 8-17 (
< .001), respectively). Non-rectal cancer was more common in the non-CCRP group (81.5% vs. 57.6%,
< .001). The non-CCRP group had lower median Hb-value (106, IQR 87-129 vs. 117, IQR 101-136,
= .001). 85% of the non-CCRP group was found to meet one or more CCRP referral criteria, with bleeding anemia being the dominant criterion to meet.

The CCRP did not appear to improve prognostic outcomes for CRC-patients.

ClinicalTrials.gov Identifier NCT04585516.Crotonaldehyde is a highly toxic pollutant, widely present in tobacco smoke and automobile exhaust. Exposure to crotonaldehyde can cause hepatotoxicity and induce liver tumors in rats; however, the underlying mechanism is unclear. Liver cells contain many mitochondria, which serve to maintain energy levels in the body. We hypothesized that the energy metabolism disorder caused by mitochondrial dysfunction is an important cause of liver injury in rats exposed to crotonaldehyde. To test this, we randomly divided 40 male Wistar rats into four groups, and provided crotonaldehyde at 0, 2.5, 4.5, and 8.5 mg/kg for 90 days by intragastric administration. read more The results showed that crotonaldehyde exposure caused damage to liver mitochondrial structure, reduced electron-transport chain activity and ATP levels, and interfered with mitochondrial DNA transcription. In response to increased crotonaldehyde exposure, rats exhibited increased reactive oxygen species levels, decreased superoxide dismutase and glutathione activity, and activation of the caspase-mediated apoptosis pathway, as well as elevated levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, and histopathological damage. Our findings, together with those of previous reports, should help elucidate the underlying mechanism of crotonaldehyde-induced mitochondrial dysfunction and energy metabolism disorder, and provide an important direction for the prevention and clinical intervention of liver diseases caused by crotonaldehyde and aldehydes with similar structures.This study was organized to determine the efficacy and safety of deferasirox (DFX) in reducing the SF of patients with transfusion-dependent thalassemia (TDT). This is a retrospective, descriptive study of 101 transfusion- dependent patients with thalassemia major who were followed for 48 months. Twenty-nine patients who used an alternative chelator either alone or combined, who were not compliant to the treatment, changed the drug due to adverse reactions, and had multiple transfusions and did not complete 4 years of DFX use were excluded. A total 72 out of 101 patients completed the study. SF decreases were noted for the 6-12 and >18-year age groups, from a median of 1532 ng/mL to 1190 ng/mL, and from 1386 ng/mL to 1165 ng/mL, respectively (p > 0.05). The proportion of patients with SF concentrations >2000 ng/mL is decreased (29% at baseline decreased to 15% at the end of the study) during the 48 months. The median SF of those who used 30 mg/kg/day (n = 34) group's SF concentrations decreased from a median of 1575 ng/mL to 1209 ng/mL (p = 0.029). The decrease of median SF values for Syrian patients was statistically significant (p = 0.043). Most common adverse events were gastric irritation symptoms (19.4%). The total DFX discontinuation ratio was calculated as 9.7%. Although dosages between 25-30 mg/kg/day are adequate to stabilize SF concentrations higher dosages are needed to achieve a statistically significant decrease.
Some ecological studies found lower rates of opioid overdose in states with liberalized cannabis legislation, but results are mixed, and the association has not been analyzed in individuals. We quantified the association between cannabis use and nonfatal opioid overdose among individuals enrolled in methadone maintenance treatment (MMT) for opioid use disorder (OUD).

We recruited a convenience sample of individuals enrolled in four MMT clinics in Washington State and southern New England who completed a one-time survey.Descriptive statistics and multivariate logistic regression compared the prevalence and risk of nonfatal opioid overdose in the past 12 months between participants reporting frequent (at least weekly) or infrequent (once or none) cannabis use in the past month.

Of 446 participants, 35% (
 = 156) reported frequent cannabis use and 7% (
 = 32) reported nonfatal opioid overdose in the past year. The prevalence of nonfatal opioid overdose was 3% among reporters of frequent cannabis use, and 9% among reporters of infrequent/no use (
