In this study, the function and regulation of long non-coding RNA (lncRNA) LINC00342 in lung adenocarcinoma were investigated. From The Cancer Genome Atlas (TCGA) datasets and Gene Expression Omnibus (GEO) datasets, LINC00342 was found to be up-regulated in lung adenocarcinoma. The high expression of LINC00342 was also validated in lung cancer cell lines. LINC00342 induced invasion and epithelial-mesenchymal transition (EMT) process of A549 cells. By analyzing GEO datasets, TPBG was confirmed positively correlated to LINC00342 and highly expressed in lung adenocarcinoma. In addition, TPBG induced invasion and EMT process of A549 cells. Through bioinformatics analysis and luciferase assay, miR-15b was validated as a direct target of both LINC00342 and TPBG. Ectopic miR-15 expression repressed LINC00342 and TPBG. Interestingly, LINC00342 overexpression inhibited miR-15b and induced TPBG, whereas ectopic TPBG unchanged LINC00342 and miR-15b levels. In conclusion, LINC00342 promotes metastasis of lung adenocarcinoma through inducing TPBG targeted by miR-15b.
During intraoperative neurophysiological monitoring of motor pathways, two types of transcranial electrical stimulation are available, i.e., constant-current and constant-voltage stimulation. click here Few previous studies, performed only during spinal surgery, analyzed and compared them during intraoperative neurophysiological monitoring. The aim of our study was to compare these two stimulation techniques for eliciting motor-evoked potentials during intraoperative neurophysiological monitoring in a group of patients affected by supratentorial lesions.

Supratentorial lesions from 16 patients were retrospectively collected and analyzed. Motor-evoked potentials were performed only from transcranial electrical stimulation because the inability to place the subdural strip electrodes correctly did not permit to perform direct cortical stimulation. At the beginning of surgery, in each patient, motor-evoked potentials were monitored by using both "fast-charge" constant-voltage and "slow-charge" constant-current stimulation. Several neurophysiological parameters were collected and compared between the two stimulation techniques by means of statistical analysis.

"Fast-charge" constant-voltage stimulation allowed statistically higher efficiency rates for eliciting motor-evoked potentials compared with "slow-charge" constant-current stimulation, both for upper and lower limbs. We also found that threshold and maximal charge as well as charge density were significantly lower during constant-voltage stimulation, thus lowering the potential tissue damage.

"Fast-charge" constant-voltage transcranial electrical stimulation is feasible and safe during intraoperative neurophysiological monitoring for supratentorial surgery and may be preferable to "slow-charge" constant-current stimulation.

This systematic review aims to identify and critically evaluate the available evidence on the impact of switches in pill appearance/packaging on patient's behavior.

Studies from inception to March 2021 were searched across MEDLINE through PubMed, the Cochrane Library, Embase, and Scopus. Included studies carried out an original evaluation in English or Spanish language that evaluated the impact of switches in pill appearance/packaging on patient's behavior. Two authors independently extracted study data and evaluated studies for methodological quality according to the STROBE guidelines.

Ten studies were included, and the mean (SD) number of STROBE criteria satisfied was 17.2 (3.9). Three of 5 studies found a significant association between change in pill appearance and persistence to treatment; the 3 studies that evaluated the impact of a change on adherence to treatment found a significant association; 1 of the 2 studies that evaluated the relationship between a change a clinical outcome found a significant association with the prevalence of uncontrolled blood pressure; and 1 study showed lower rates of switchbacks to the branded product compared with patients who switched to generic drug products, with different appearance.

This systematic review showed an impact of the change in pill/package appearance on patients' behavior in 7 of the 10 studies included. Generic switching may lead to unintended consequences on patients' behavior, mainly regarding adherence to treatment.

We aimed to determine if polygenic risk scores (PRSs) based on external genome-wide association studies (GWASs) of these disorders could improve genetic identification of mood disorders.Methods We combined 6 independent family studies that had genetic data and diagnoses for mood disorders that were made using different editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). We identified mood disorders, either concurrently or in the future, in participants between 6 and 17 years of age using PRSs calculated using summary statistics of GWASs for ADHD, ADHD with DBD, major depressive disorder (MDD), bipolar disorder (BPD), and aggression to compute PRSs.Results In our sample of 485 youths, 356 (73%) developed a subthreshold or full mood disorder and 129 (27%) did not. The cross-validated mean areas under the receiver operating characteristic curve (AUCs) for the 7 models identifying participants with any mood disorder ranged from 0.552 in the base model of age and sex to 0.648 in the base model + all 5 PRSs. When included in the base model individually, the ADHD PRS (OR = 1.65, P  less then  .001), Aggression PRS (OR = 1.27, P = .02), and MDD PRS (OR = 1.23, P = .047) were significantly associated with the development of any mood disorder.Conclusions Using PRSs for ADHD, MDD, BPD, DBDs, and aggression, we could modestly identify the presence of mood disorders. These findings extend evidence for transdiagnostic genetic components of psychiatric illness and demonstrate that PRSs calculated using traditional diagnostic boundaries can be useful within a transdiagnostic framework.Objective The concept of "deaths of despair" (suicide, overdose, and alcohol-related liver disease) highlights the importance of detecting and understanding the course of co-occurring depression in patients with opioid use disorder (OUD).Methods In a 24-week trial of 570 patients with DSM-5-defined OUD randomized to buprenorphine-naloxone (BUP-NX) or extended-release naltrexone (XR-NTX) from January 2014 to January 2017, the prevalence of depression (assessed with Hamilton Depression Rating Scale [HDRS]) was examined at baseline and after 4 weeks of treatment, and the association between depression and relapse to opioid use was explored using logistic regression.Results Among 473 patients who initiated medication, 14.2% (67/473) had moderate/severe depression (HDRS ≥ 17) and 34.9% (165/473) had mild depression (8 ≤ HDRS ≤ 16) at baseline. Patients with moderate/severe depression had more frequent histories of anxiety disorders and suicidal ideation. After 4 weeks of treatment, approximately two-thirds of participants with depression either responded (HDRS reduced ≥ 50% from baseline) or remitted (HDRS ≤ 7), with no significant differences between medication treatment groups. Those with moderate/severe depression were less likely to remit (52.8%; 28/53) compared to those with mild depression (76%; 98/129) at week 4 (OR = 0.43, 95% CI = 0.21-0.89, P = .02). Further, those who remitted at week 4 had lower, but not significantly different, risk of relapse to opioids compared to those who did not remit (OR = 0.55, 95% CI = 0.28-1.08, P = .08).Conclusions Depression is common among patients with OUD and often remits after initiation of BUP-NX or XR-NTX, although when it does not remit it may be associated with worse opioid use outcome. Depression should be screened and followed during initiation of treatment and, when it does not remit, specific depression treatment should be considered.Trial Registration ClinicalTrials.gov identifier NCT02032433.Mounting evidence suggests that extracellular vesicles (EVs) are effective communicators in biological signalling in cardiac physiology and pathology. However, the role of EVs in cardiac injury, particularly in ischemic myocardial scenarios, has not been fully elucidated. Here, we report that acute myocardial infarction (AMI)-induced EVs can impair cardiomyocyte survival and exacerbate cardiac injury. EV-encapsulated miR-503, which is enriched during the early phase of AMI, is a critical molecule that mediates myocardial injury. Functional studies revealed that miR-503 promoted cardiomyocyte death by directly binding to peroxisome proliferator-activated receptor gamma coactivator-1β (PGC-1β) and a mitochondrial deacetylase, sirtuin 3 (SIRT3), thereby triggering mitochondrial metabolic dysfunction and cardiomyocyte death. Mechanistically, we identified endothelial cells as the primary source of miR-503 in EVs after AMI. Hypoxia induced rapid H3K4 methylation of the promoter of the methyltransferase-like 3 gene (METTL3) and resulted in its overexpression. METTL3 overexpression evokes N6-methyladenosine (m6 A)-dependent miR-503 biogenesis in endothelial cells. In summary, this study highlights a novel endogenous mechanism wherein EVs aggravate myocardial injury during the onset of AMI via endothelial cell-secreted miR-503 shuttling.Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are incretins that play an important role in glucose metabolism, by increasing glucose-induced insulin secretion from pancreatic β-cells and help regulate bodyweight. Although they show a similar action on glucose-induced insulin secretion, two incretins are distinct in various aspects. GIP is secreted from enteroendocrine K cell mainly expressed in the upper small intestine, and GLP-1 is secreted from enteroendocrine L cells mainly expressed in the lower small intestine and colon by the stimulation of various nutrients. The mechanism of GIP secretion induced by nutrients, especially carbohydrates, is different from that of GLP-1 secretion. GIP promotes fat deposition in adipose tissue, and contributes to fat-induced obesity. In contrast, GLP-1 participates in reducing bodyweight by suppressing food consumption and/or slowing gastric emptying. There is substantial evidence that GIP and GLP-1 might differently contribute to bodyweight control. Although meal contents influence both glycemic and weight control, we do not fully understand whether incretin actions differ depending on the contents of the meal and what kind of signaling is involved in its context. We focus on the molecular mechanism of GIP secretion induced by nutrients, as well as the roles of GIP in weight changes caused by various diets.
