The sample size is 12,500 subjects. The ENDPAC score will be calculated only in those randomized to the Intervention arm, with 50% (n = 3125) expected to have a high ENDPAC score. Consenting subjects in the high ENDPAC group will undergo CT imaging for PDAC detection and an estimate of potential harm. The effectiveness and efficacy evaluation will compare proportions of late stage PDAC between Intervention and Observation arm per randomization assignment or per protocol, respectively, with a planned interim analysis. The study is designed to improve the detection of sporadic PDAC when surgical intervention is possible.
Hospital readmissions are estimated to cost $17.4 billion per year in the Medicare population alone, with readmission rates as high as 30% for patients undergoing complex abdominal surgery. Improved transitional care and self-monitoring may reduce preventable readmissions for such high-risk populations. In this study, we will conduct a single-institution randomized controlled trial (RCT) to assess the effect of a novel transitional care mobile app, MobiMD, on hospital readmission in complex abdominal surgery patients.

Three hundred patients will be randomized 11 to standard of care (SOC) versus SOC plus MobiMD app in a parallel, single-blinded, two-arm RCT. Eligible patients are those who undergo complex abdominal surgery in the division of Surgical Oncology, Colorectal Surgery or Transplant Surgery. The MobiMD app provides push notification reminders directly to the patient's smart device, prompting them to enter clinical data and patient-reported outcomes. Clinical data collected via the MobiMD app include vital signs, red flag symptoms, daily wound and surgical drain images, ostomy output, drain output, medication compliance, and wound care compliance. These data are reviewed daily by a physician. The primary outcome is the proportion of participants readmitted to the hospital within 30days of surgery. Secondary outcomes are 90-day hospital readmission, emergency department and urgent care visits, complication severity, and total readmission cost.

If effective, mobile health apps such as MobiMD could be routinely integrated into surgical transitional care programs to minimize unnecessary hospital readmissions, emergency department visits and healthcare resource utilization. Clinical trials identifier NCT04540315.

Clinical trials identifier NCT04540315.Digital health technologies (DHTs) enable us to measure human physiology and behavior remotely, objectively and continuously. With the accelerated adoption of DHTs in clinical trials, there is an unmet need to identify statistical approaches to address missing data to ensure that the derived endpoints are valid, accurate, and reliable. It is not obvious how commonly used statistical methods to handle missing data in clinical trials can be directly applied to the complex data collected by DHTs. Meanwhile, current approaches used to address missing data from DHTs are of limited sophistication and focus on the exclusion of data where the quantity of missing data exceeds a given threshold. High-frequency time series data collected by DHTs are often summarized to derive epoch-level data, which are then processed to compute daily summary measures. In this article, we discuss characteristics of missing data collected by DHT, review emerging statistical approaches for addressing missingness in epoch-level data including within-patient imputations across common time periods, functional data analysis, and deep learning methods, as well as imputation approaches and robust modeling appropriate for handling missing data in daily summary measures. We discuss strategies for minimizing missing data by optimizing DHT deployment and by including the patients' perspectives in the study design. We believe that these approaches provide more insight into preventing missing data when deriving digital endpoints. We hope this article can serve as a starting point for further discussion among clinical trial stakeholders.In phase I trials, it is the top priority of clinicians to effectively treat patients and minimize the chance of exposing them to subtherapeutic and overly toxic doses, while exploiting patient information. Motived by this practical consideration, we revive the one parameter linear dose-finder developed in 1970s to accommodate a continuous toxicity response in the phase I cancer clinical trials, which is called the two parameters linear dose-finder (2PLD). The 2PLD is a fully Bayesian model that assumes a linear relationship between toxicity response and dose. We suggest a dose search algorithm based on the 2PLD to exploit the grades of toxicities from multiple adverse events to align with Common Toxicity Criteria for Adverse Events provided by the National Cancer Institute. The proposed search procedure suggests an optimal dose to each patient by using accrued patients' information while controlling the posterior probability of overdose. The heterogeneity of patients in dose reaction is addressed by making a fully Bayesian inference about the standard deviation of toxicity responses. The 2PLD can be an attractive tool for clinical scientists due to its parsimonious description of a toxicity-dose curve and medical interpretation as well as an automatic posterior computation. We illustrate the performance of this design using simulation data to identify the maximum tolerated dose.Tuberculosis (TB) remains a significant cause of morbidity and mortality in the modern world. Abdominal TB is a rare form of extrapulmonary TB that has been found to affect children without comorbidities in particular, although exact numbers are unavailable because of lack of data and its rarity. The diagnosis of abdominal TB remains a challenge because of its unspecific clinical features and unclear recommendations regarding the best diagnostic tools. We report 4 cases of children with abdominal TB diagnosed at The Hospital of Lithuanian University of Health Sciences Kaunas clinics from 2008 to 2018 at the Department of Paediatric Surgery. All these cases are exceptional. The final diagnosis of abdominal TB was confirmed only after diagnostic laparoscopy and biopsy. Moreover, we suggest that QuantiFERON test and ascitic fluid analysis with serum ascites albumin gradient and adenosine deaminase tests should be performed before more invasive interventions. MCC950 Laparoscopy with biopsy should be performed only in unclear cases.
Health care workers (HCW) are among the highest risk groups for acquisition of COVID-19 because of occupational exposures. The WHIP COVID-19 Study aimed to evaluate the safety and efficacy of hydroxychloroquine (HCQ) as chemoprophylaxis for SARS-CoV-2 infection in this population.

HCW, first responders, and other occupationally high-risk participants were enrolled in a randomized, placebo-controlled clinical study of HCQ from April to October 2020. The trial compared daily versus weekly HCQ with placebo and with a prospective cohort on HCQ for autoimmune diseases. Participants were followed for 8 weeks. Serology or a positive polymerase chain reaction test was used to determine laboratory confirmed clinical cases.

A total of 624 participants were randomized to placebo (n = 200), weekly HCQ (n = 201), daily HCQ (n = 197). For the primary safety end point, 279 (44.7%) participants experienced adverse event (AE) level II or lower (total AEs n = 589), similar rates in all randomized groups (P = .188) with no hospitalizations or interventions required. Only 4 laboratory confirmed COVID-19 cases occurred, with 2 in the placebo arm and one in each HCQ randomized arm.

This randomized placebo-controlled trial was able to demonstrate the safety of HCQ outpatient chemoprophylaxis in high-risk groups against COVID-19. Future studies of chemoprophylaxis for SARS-CoV-2 are needed as the epidemic continues worldwide.

The purpose of this meta-analysis (PROSPERO number CRD42021243204) is to perform extensive and penetrating analyses on the risk factors associated with reactivation or reinfection.

We searched PubMed and Embase using search terms. Risk factors (including gender, length of time between first onset and recurrent diagnosis, extrapulmonary tuberculosis, sputum smear, pulmonary cavity, Beijing family strains, diabetes, HIV infection, history of imprisonment, and immigration) were analyzed. The pooled risk ratio (RR) and 95% confidence interval (CI) were calculated with STATA 15.1. Heterogeneity was evaluated by I
and P values.

The meta-analysis included 25 studies with a total of 1,477 recurrent patients. After subgroup analysis, sensitivity analysis, and testing for publication bias, it was concluded that time spanning less than two years (RR=1.56, 95% CI 1.33-1.85) was a risk factor for endogenous reactivation, whereas coinfection with HIV (RR=0.72, 95% CI 0.63-0.83), Beijing family genotype (RR=0.46, 95% CI 0.32-0.67), history of imprisonment (RR=0.36, 95% CI 0.16-0.81), and immigration (RR=0.66, 95% CI 0.53-0.82) were associated with exogenous reinfection.

The recurrence interval is a risk factor for the endogenous reactivation of tuberculosis. link2 Infection with Beijing family strains, coinfection with HIV, imprisonment, and immigration contribute to the risk of exogenous reinfection.

The difficulty in diagnosing CMV anterior uveitis may delay adequate treatment and affect outcomes. We sought to review systemically the overall clinical characteristics and compare treatment outcomes in CMV anterior uveitis and endotheliitis. A literature search was performed, and studies describing clinical characteristics, treatment regimens, and outcomes that included more than 5 treated eyes were included. In these 23 studies, acute CMV anterior uveitis commonly presented with high intraocular pressure (95.31%, 95% CI 90.45-98.60) and mild anterior chamber inflammation (cells >2+ = 3.18%, 95% CI 0.21-0.54). About two-thirds of CMV endotheliitis cases presented with high intraocular pressure and coin-shaped corneal lesions. Acute CMV anterior uveitis showed good clinical response to topical 0.15% ganciclovir (GCV) gel or oral valganciclovir (VGCV) (90%, 95% CI 74-100% and 95%, 95% CI 88-100%, respectively). For chronic CMV anterior uveitis, both topical GCV and oral VGCV yielded comparable results. Topical 0.5-2% GCV or a combination of topical and oral VGCV for CMV endotheliitis both resulted in good clinical response. Recurrence of inflammation was common after cessation of maintenance therapy. Overall, topical GCV resulted in an optimal outcome for CMV anterior uveitis. Escalated concentration and frequency of usage are needed for chronic CMV anterior uveitis and endotheliitis. link3 Adequate induction and maintenance phases of anti-CMV treatment seem necessary to prevent recurrences.
