Data augmentation approach for language identification in imbalanced bilingual code-mixed social media datasets

Addressing the problem of language identification in code-mixed datasets poses notable challenges due to data scarcity and high confusability in bilingual contexts. These challenges are further amplified by the associated imbalance and noise characteristic of social media data, complicating efforts to optimize performance. This paper introduces an augmentation approach designed to enhance language identification in bilingual code-mixed social media data. By incorporating reverse translation, semantic similarity, and sampling techniques alongside customized reprocessing strategies, our approach offers a comprehensive solution to these complex issues. To evaluate the effectiveness of the proposed approach, experiments were conducted on language identification at both the sentence and word levels. The results demonstrated the potential of the approach in optimizing language identification performance, offering a compelling combination of generation techniques for addressing the challenges of language identification in code-mixed data

Social Media Sentiment Analysis and Opinion Mining in Public Security : Taxonomy, Trend Analysis, Issues and Future Directions

The interest in social media sentiment analysis and opinion mining for public security events has increased over the years. The availability of social media platforms for communication provides a valuable source of information for sentiment analysis and opinion mining research. The content shared across the media gives potential input to the physical environment and social phenomena related to public security threats. The input has been used to: monitor public security threats or emergency events, analyzing sentiment and opinionated data for threat management and the detection of public security threat events using geographic location-based sentiment analysis. However, a systematic survey that describes the trends and latest developments in this domain is unavailable. This paper presents a survey of social media sentiment analysis and opinion mining for public security. This paper aims to: understand the progress of the current state-of-the-art, identify the research gaps, and propose potential future directions. In total, 200 articles published from 2016 to 2023 were considered in this survey. The taxonomy shows the key attributes and limitations of the work presented in the surveyed articles. Subsequently, the potential future direction of work on sentiment analysis in the public security domain is suggested for interested researchers

Strategic Plan: 2018 and Forward - Jefferson Center for Interprofessional Practice & Education

Founded in 2007, the Jefferson Center for Interprofessional Practice and Education (JCIPE) is one of the premier interprofessional education centers in the U.S. Our center is dedicated to improving interprofessional care (IPC) through implementing and evaluating patient-centered education throughout the Thomas Jefferson University curriculum. We offer robust trainings and educational opportunities, provide innovative teaching models and evidence-based practices to help support emerging priorities in healthcare. To coincide with our 10-year anniversary and the transition to new leadership, we engaged the Jefferson Doctor of Management program in Strategic Leadership (DSL) to help us to reimagine and rethink our interests and needs in the increasingly complex and changing environment. With their facilitation we drew on the experience of more than 120 JCIPE stakeholders including co-directors, staff advisors, faculty, deans, student learners, community leaders, health mentors, and patients. We adopted a system-thinking framework and applied interactive design planning methodology to create the design for an ideal center for interprofessional care. From this prototype, we created our new strategic plan, business model, and roadmap. We believe our design experience and deep understanding of IPC will lead us to an even more prominent role as a model of excellence for interprofessional and professional practice and education

Identification of a novel splice variant form of the influenza a virus m2 ion channel with an antigenically distinct ectodomain

Segment 7 of influenza A virus produces up to four mRNAs. Unspliced transcripts encode M1, spliced mRNA2 encodes the M2 ion channel, while protein products from spliced mRNAs 3 and 4 have not previously been identified. The M2 protein plays important roles in virus entry and assembly, and is a target for antiviral drugs and vaccination. Surprisingly, M2 is not essential for virus replication in a laboratory setting, although its loss attenuates the virus. To better understand how IAV might replicate without M2, we studied the reversion mechanism of an M2-null virus. Serial passage of a virus lacking the mRNA2 splice donor site identified a single nucleotide pseudoreverting mutation, which restored growth in cell culture and virulence in mice by upregulating mRNA4 synthesis rather than by reinstating mRNA2 production. We show that mRNA4 encodes a novel M2-related protein (designated M42) with an antigenically distinct ectodomain that can functionally replace M2 despite showing clear differences in intracellular localisation, being largely retained in the Golgi compartment. We also show that the expression of two distinct ion channel proteins is not unique to laboratory-adapted viruses but, most notably, was also a feature of the 1983 North American outbreak of H5N2 highly pathogenic avian influenza virus. In identifying a 14th influenza A polypeptide, our data reinforce the unexpectedly high coding capacity of the viral genome and have implications for virus evolution, as well as for understanding the role of M2 in the virus life cycle

Canagliflozin and Renal Outcomes in Type 2 Diabetes and Nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to 300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m 2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

The incidence of fluoroquinolone resistant infections after prostate biopsy--are fluoroquinolones still effective prophylaxis?

PURPOSE: Fluoroquinolones have been shown to decrease infective complications after prostate biopsy. However, fluoroquinolone resistance is emerging. We quantified contemporary rates of infective complications and the incidence of fluoroquinolone resistant infections after prostate biopsy under fluoroquinolone prophylaxis. MATERIALS AND METHODS: We retrospectively evaluated the records of 1,273 patients who underwent prostate biopsy at New York Harbor Veterans Affairs Hospital from January 2004 to December 2006. Patients received levofloxacin or gatifloxacin. Using the Veterans Affairs computerized patient record system we reviewed all patient visits within 1 month after prostate biopsy. Visits were queried for infective symptoms. Positive cultures were evaluated for resistance patterns. The annual and overall incidence of infective complications and fluoroquinolone resistant infections was calculated. RESULTS: Of 1,273 patients 31 (2.4%) presented with infective symptoms after biopsy. The overall incidence of fluoroquinolone resistant infections was 1.2% (15 cases). When stratified by year, there were statistically significant increases in the incidence of infective complications and fluoroquinolone resistance from 2004 to 2006. Of the positive cultures those from 89% of patients yielded Escherichia coli and 90% were fluoroquinolone resistant. Fluoroquinolone resistant E. coli were also resistant to gentamicin in 22% of cases, trimethoprim/sulfamethoxazole in 44%, piperacillin in 72% and ampicillin in 94%. However, 100% sensitivity was demonstrated for amikacin, ceftazidime and ceftriaxone. CONCLUSIONS: Fluoroquinolones are still effective as antibiotic prophylaxis for prostate biopsies but there is an increase in infective complications and fluoroquinolone resistance. When patients present with post-prostate biopsy infective symptoms, almost 50% are associated with fluoroquinolone resistant pathogens. Empirical treatment with ceftriaxone, ceftazidime or amikacin should be initiated until culture specific therapy can be implemented
