Major depressive disorder is highly prevalent worldwide and has been affecting an increasing number of people each year. Current first line antidepressants show merely 37% remission, and physicians are forced to use a trial-and-error approach when choosing a single antidepressant out of dozens of available medications. We sought to identify a method of testing that would provide patient-specific information on whether a patient will respond to a medication using in vitro modeling. Patient-derived lymphoblastoid cell lines from the Sequenced Treatment Alternatives to Relieve Depression study were used to rapidly generate cortical neurons and screen them for bupropion effects, for which the donor patients showed remission or non-remission. We provide evidence for biomarkers specific for bupropion response, including synaptic connectivity and morphology changes as well as specific gene expression alterations. These biomarkers support the concept of personalized antidepressant treatment based on in vitro platforms and could be utilized as predictors to patient response in the clinic.BACKGROUND Psoriasis is a chronic inflammatory skin disease associated with multiple comorbidities including psoriatic arthritis (PsA), atherosclerotic disease, metabolic syndrome, diabetes, hypertension, obesity, and depression. Interestingly, nonischemic cardiomyopathy, especially dilated cardiomyopathy (DCM), has been associated with psoriasis and reported in only in a few cases in the literature. CASE REPORT We report the rare case of a 58-year-old man with a medical history of untreated severe psoriasis and PsA who presented with a sudden onset of shortness of breath. Laboratory and radiographic studies showed an elevated level of B-type natriuretic peptide and acute bilateral pulmonary edema. The patient had normal coronary arteries on cardiac catheterization and echocardiography showed newly diagnosed DCM with systolic and diastolic dysfunction. Cardiac magnetic resonance imaging was consistent with nonischemic DCM (NIDCM) with no evidence of hypertrophy, infiltrative process, or edema. The patient was diagnosed with acute congestive heart failure secondary to NIDCM in the setting of long-standing untreated psoriasis. He responded well to diuretics, was placed on guideline-directed medical therapy, and was discharged with a LifeVest personal cardiac defibrillator. As an outpatient, the patient was started on secukinumab, a monoclonal antibody against interleukin-17A. At his last follow-up appointment, the patient reported improvement in his cardiac symptoms and resolution of his psoriatic skin lesions; repeat echocardiography showed improvement in his ejection fraction. CONCLUSIONS Although studies have shown a higher prevalence of cardiovascular disease in patients with psoriasis, an association with NIDCM has not been studied sufficiently. We recommend further studies of the prevalence, pathogenesis, screening, and management of NIDCM in patients with psoriasis.BACKGROUND Cornus officinalis (CO), also known as ‘Shanzhuyu’, is one of the most common traditional Chinese herbs used against osteoporosis. Although previous studies have found that CO has beneficial effects in alleviating osteoporosis, its mechanisms remain unclear. MATERIAL AND METHODS In this study, we applied system bioinformatic approaches to investigate the possible therapeutic mechanisms of CO against osteoporosis. We collected the active ingredients of CO and their targets from the TCMSP, BATMAN-TCM, and ETCM databases. Next, we obtained the osteoporosis targets from differentially expressed mRNAs from the Gene Expression Omnibus (GEO) gene series (GSE35958). Next, the shared genes of the CO pharmacological targets and osteoporosis-related targets were selected to construct the protein-protein interaction network, based on the results from the STRING database. Subsequently, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were carried out by using the clusterProfiler package in R software. RESULTS In all, there were 58 unique CO compounds and 518 therapeutic targets. Based on the GO and KEGG enrichment results of 98 common genes, we selected the top 25 terms, based on the terms’ P values. We found that the anti-osteoporotic effect of CO may mostly involve the regulation of calcium metabolism and reactive oxygen species, and the estrogen signaling pathway and osteoclast differentiation pathway. CONCLUSIONS We found the possible mechanisms of CO in treating osteoporosis may be based on multiple targets and pathways. We also provided a theoretical basis and promising direction for investigating the exact anti-osteoporotic mechanisms of CO.This meta-analysis aimed to evaluate the impact of prepackaged low-residue diet (PLRD) on bowel preparation for colonoscopy. We searched PubMed, Web of Science, EMBASE, and Cochrane Library databases from inception to August 2020. Randomized controlled trials (RCTs) comparing PLRD with clear liquid diet (CLD) or self-prepared LRD were considered for inclusion. The analysis calculated the odds ratio (OR) for the rate of adequate bowel preparation, patient tolerance, willingness to repeat bowel preparation, tolerability of bowel preparation, and overall adverse effects. Five RCTs published between 2006 and 2019 (N = 561) were included in our meta-analysis. Compared with the traditional CLD or self-prepared LRD, PLRD showed significantly higher rates of adequate bowel preparation (OR, 2.16; 95% confidence interval [CI], 1.18-3.98; p = .01), patient tolerance (OR, 1.99; 95% CI, 1.30-3.07; p = .002), and willingness to repeat the bowel preparation (OR, 1.68; 95% CI, 1.05-2.70; p = .03), with no differences in adverse events (OR, 0.93; 95% CI, 0.59-1.46; p = .75). Prepackaged low-residue diet improved bowel preparation quality, patient tolerance, and willingness to repeat bowel preparations. Importantly, PLRD does not increase the incidence of adverse events. This suggests that it is effective and safe to use PLRD for bowel preparation before colonoscopy.Esophagogastroduodenoscopy can be uncomfortable and distressing with many patients opting for conscious sedation over topical local anesthetic spray. Transnasal endoscopy is an alternative and we sought to assess how easily it could be introduced to a district general hospital and how acceptable patients found it. click here Selected patients requiring diagnostic endoscopy were offered transnasal endoscopy with topical nasal anesthetic by clinicians new to transnasal endoscopy but competent at esophagogastroduodenoscopy. Postal feedback questionnaires were used to assess comfort, distress, recollection of periprocedural consultation, and overall experience (visual analog scale 1-10). A total of 213 transnasal endoscopy procedures were undertaken with 207 completed successfully (97.2%). Two patients (0.9%) had self-limiting epistaxis and no patient required admission. One hundred (47%) questionnaires were returned including 98 from those with completed transnasal endoscopy. Thirty-three (33%) had previous esophagogastroduodenoscopy and 28 (85%) reported a preference for transnasal endoscopy.
