Studi fenomenologi: perilaku self disclosure pada mahasiswa pengguna media sosial twitter di tengah pandemi Covid 19

Kondisi Pandemi Covid 19 menyebabkan adanya pembatasan sosial yang diterapkan oleh pemerintah. Pembatasan tersebut berpengaruh pada ruang sosial yang semakin mengecil sehingga meningkatkan perilaku self disclosure pada media sosial, khususnya twitter. Peningkatan perilaku self disclosure pada media sosial twitter dapat ditelusuri pada survey yang dilakukan oleh we are social bahwa twitter menjadi media sosial ke lima yang paling sering digunakan di Indonesia. Penelitian ini bertujuan untuk mengetahui bagaimana bentuk self disclosure yang terjadi, apa alasan dibalik perilaku self disclosure, hal apa saja yang menjadi pedoman dalam melakukan self disclosure, apakah enggagement antara pengguna dan followers memiliki peranan pada perilaku self disclosure . Penelitian ini menggunakan jenis penelitian kualitatif dengan pendekatan fenomenologi yang dilakukan pada mahasiswa pengguna twitter yang berdomisili di pemalang. Narasumber penelitian ini berjumlah 5 orang yang dipilih berdasarkan kriteria. Teknik pengumpulan data yang peneliti gunakan adalah wawancara semi terstruktur dan juga observasi yang dianalisis serta disajikan dalam bentuk deskriptif. Hasil dari penelitian ini ditemukan bahwa narasumber cenderung terbuka dan senang melakukan perilaku self disclosure. Hal tersebut disebabkan oleh perasaan lega yang muncul setelah menyalurkan emosi tanpa takut diketahui oleh orang yang mengenal narasumber di dunia nyata. Bentuk keterbukaan seringkali berupa tweet mengenai perasaan pribadi dan aktivitas keseharian narasumber. Meskipun begitu narasumber cenderung enggan mengungkapkan masalah terkait keluarga dan juga sex

Transcriptomic landscape of lncRNAs in inflammatory bowel disease

BACKGROUND: Inflammatory bowel disease (IBD) is a complex multi-factorial inflammatory disease with Crohn’s disease (CD) and ulcerative colitis (UC) being the two most common forms. A number of transcriptional profiling studies have provided compelling evidence that describe the role of protein-coding genes and microRNAs in modulating the immune responses in IBD. METHODS: In the present study, we performed a genome-wide transcriptome profiling of lncRNAs and protein-coding genes in 96 colon pinch biopsies (inflamed and non-inflamed) extracted from multiple colonic locations from 45 patients (CD = 13, UC = 20, controls = 12) using an expression microarray platform. RESULTS: In our study, we identified widespread dysregulation of lncRNAs and protein-coding genes in both inflamed and non-inflamed CD and UC compared to the healthy controls. In cases of inflamed CD and UC, we identified 438 and 745 differentially expressed lncRNAs, respectively, while in cases of the non-inflamed CD and UC, we identified 12 and 19 differentially expressed lncRNAs, respectively. We also observed significant enrichment (P-value <0.001, Pearson’s Chi-squared test) for 96 differentially expressed lncRNAs and 154 protein-coding genes within the IBD susceptibility loci. Furthermore, we found strong positive expression correlations for the intersecting and cis-neighboring differentially expressed IBD loci-associated lncRNA-protein-coding gene pairs. The functional annotation analysis of differentially expressed genes revealed their involvement in the immune response, pro-inflammatory cytokine activity and MHC protein complex. CONCLUSIONS: The lncRNA expression profiling in both inflamed and non-inflamed CD and UC successfully stratified IBD patients from the healthy controls. Taken together, the identified lncRNA transcriptional signature along with clinically relevant parameters suggest their potential as biomarkers in IBD.

Thiopurine withdrawal during sustained clinical remission in inflammatory bowel disease: relapse and recapture rates, with predictive factors in 237 patients

Background: Thiopurines (azathioprine and mercaptopurine) remain integral to most medical strategies for maintaining remission in Crohn's disease (CD) and ulcerative colitis (UC). Indefinite use of these drugs is tempered by long-term risks. While clinical relapse is noted frequently following drug withdrawal, there are few published data on predictive factors. Aim: To investigate the success of planned thiopurine withdrawal in patients in sustained clinical remission to identify rates and predictors of relapse. Methods: This was a multicentre retrospective cohort study from 11 centres across the UK. Patients included had a definitive diagnosis of IBD, continuous thiopurine use ≥3 years and withdrawal when in sustained clinical remission. All patients had a minimum of 12 months follow-up post drug withdrawal. Primary and secondary end points were relapse at 12 and 24 months respectively. Results: 237 patients were included in the study (129 CD; 108 UC). Median duration of thiopurine use prior to withdrawal was 6.0 years (interquartile range 4.4–8.4). At follow-up, moderate/severe relapse was observed in 23% CD and 12% UC patients at 12 months, 39% CD and 26% UC at 24 months. Relapse rate at 12 months was significantly higher in CD than UC (P = 0.035). Elevated CRP at withdrawal was associated with higher relapse rates at 12 months for CD (P = 0.005), while an elevated white cell count was predictive at 12 months for UC (P = 0.007). Conclusion: Thiopurine withdrawal in the context of sustained remission is associated with a 1-year moderate-to-severe relapse rate of 23% in Crohn's disease and 12% in ulcerative colitis

Cross-species high-resolution transcriptome profiling suggests biomarkers and therapeutic targets for ulcerative colitis

Background: Ulcerative colitis (UC) is a disorder with unknown etiology, and animal models play an essential role in studying its molecular pathophysiology. Here, we aim to identify common conserved pathological UC-related gene expression signatures between humans and mice that can be used as treatment targets and/or biomarker candidates.Methods: To identify differentially regulated protein-coding genes and non-coding RNAs, we sequenced total RNA from the colon and blood of the most widely used dextran sodium sulfate Ulcerative colitis mouse. By combining this with public human Ulcerative colitis data, we investigated conserved gene expression signatures and pathways/biological processes through which these genes may contribute to disease development/progression.Results: Cross-species integration of human and mouse Ulcerative colitis data resulted in the identification of 1442 genes that were significantly differentially regulated in the same direction in the colon and 157 in blood. Of these, 51 genes showed consistent differential regulation in the colon and blood. Less known genes with importance in disease pathogenesis, including SPI1, FPR2, TYROBP, CKAP4, MCEMP1, ADGRG3, SLC11A1, and SELPLG, were identified through network centrality ranking and validated in independent human and mouse cohorts.Conclusion: The identified Ulcerative colitis conserved transcriptional signatures aid in the disease phenotyping and future treatment decisions, drug discovery, and clinical trial design

On-demand treatment in patients with oesophagitis and reflux symptoms: comparison of lansoprazole and omeprazole.

BACKGROUND: There are few data on how patients on maintenance treatment of reflux oesophagitis take their medication. This study was designed to investigate the dosing patterns of patients on on-demand treatment and to compare lansoprazole with omeprazole in this regard. METHODS: Patients with reflux oesophagitis, initially treated until absence of symptoms, took capsules of either lansoprazole (30 mg) or omeprazole (20 mg) for 6 months; they were instructed to take the medication only when reflux symptoms occurred. In order to document dosing patterns, the medication was dispensed in bottles supplied with a Medication Event Monitoring System recording date and time the bottles were opened. There were regular follow-up visits with assessment of symptoms. RESULTS: Three-hundred patients were eligible for analysis according to 'all patients treated'. A dosing pattern was found of an increased intake mornings and evenings and constant intervals between intakes. Although there was no correlation between oesophagitis grade or initial symptoms and the amount of medication consumed, the patients had significantly fewer reflux symptoms the more medication they consumed. There was no difference in the number of capsules consumed between the lansoprazole (0.73 capsules/day) and omeprazole groups (0.71 capsules/day). Nor was there any difference between the groups in reflux symptoms during the course of the study. CONCLUSION: Despite rigorous instructions to take medication on demand, the results suggest that it is patient habits more so than symptoms that determine the frequency and interval of medication intake. Symptoms are not therefore decisive for the amount of medication consumed
