Long-Term Survival and Regeneration Following Transplantation of 3D-Printed Biodegradable PCL Tracheal Grafts in Large-Scale Porcine Models.

Polycaprolactone (PCL) implants in large animals show great promise for tracheal transplantation. However, the longest survival time achieved to date is only about three weeks. To meet clinical application standards, it is essential to extend the survival time and ensure the complete integration and functionality of the implant.

On the Association Between Demographic Structural Change and the Effectiveness of Nurse Staffing Policy for Inpatient Care: Evidence from Taiwan.

Purpose: This study investigates the influence of demographic changes on the effectiveness of hospital nurse staffing policy, measured by the cumulative response of inpatient care quality to adjustments in hospital nurse staffing levels in Taiwan.

Methods: The research design utilized in this study aligns with the observational time-series methodology, and a total of 99 monthly time-series observations were collected from multiple databases administered by the Taiwan government over the period from January 2015 to March 2023. Specifically, the time-varying parameter vector autoregressive and autoregressive distributed lag models were employed to investigate the association between age distribution and nurse staffing policy effectiveness.

Dachshund Homolog 1: Unveiling Its Potential Role in Megakaryopoiesis and Lethal Toxin-Induced Thrombocytopenia.

Lethal toxin (LT) is the critical virulence factor of , the causative agent of anthrax. One common symptom observed in patients with anthrax is thrombocytopenia, which has also been observed in mice injected with LT. Our previous study demonstrated that LT induces thrombocytopenia by suppressing megakaryopoiesis, but the precise molecular mechanisms behind this phenomenon remain unknown.

False Liver Metastasis by Positron Emission Tomography/Computed Tomography Scan after Chemoradiotherapy for Esophageal Cancer-Potential Overstaged Pitfalls of Treatment.

In patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy (nCRT), subsequent restaging with F-18-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) can reveal the presence of interval metastases, such as liver metastases, in approximately 10% of cases. Nevertheless, it is not uncommon in clinical practice to observe focal FDG uptake in the liver that is not associated with liver metastases but rather with radiation-induced liver injury (RILI), which can result in the overstaging of the disease. Liver radiation damage is also a concern during distal esophageal cancer radiotherapy due to its proximity to the left liver lobe, typically included in the radiation field.

A modified procedure of T-tube maneuver to treat tracheal total obstruction involving ablative bronchoscopy sparing open surgical intervention.

Objectives: The study objectives were to test an innovative T-tube procedure involving ablative bronchoscopy for the treatment of total airway occlusion and to orchestrate a safe and nontraumatic maneuver to treat intricate subglottic stenosis amenable for substituting the conventional surgical intervention.

Methods: This was an uncontrolled single-center cohort study on 1254 patients from January 2001 to June 2021. Patients underwent the modified T-tube procedure treatment for tracheal stenosis.

The association between smoking cessation and lifestyle/genetic variant rs6265 among the adult population in Taiwan.

Recent studies showed significant associations between socio-demographic, lifestyle factors, polymorphic variant rs6265, and smoking cessation behaviours. We examined rs6265 TT, TC and CC genotypes and their association with socio-demographic and other variables, including mental health status, drinking, exercise, and smoking behaviour among Taiwanese adults. Data on rs6265 were retrieved from the Taiwan Biobank, which contained genetic data collected between 2008 to 2019 from 20,584 participants (aged 30-70 years).

The Effect of a Tele-Health Intervention Program on Home-Dwelling Persons with Dementia or MCI and on Their Primary Caregivers during the Stay-at-Home-Order Period in the COVID-19 Pandemic Outbreak: Evidence from Taiwan.

Background: The Taiwanese government implemented a stay-at-home order that restricted all community-based health promotion activities for the elderly by shutting down all community care centers from May 2021 to August 2021 to control the spread of COVID-19. Community-based dementia care centers were barely able to provide dementia care services during that period.

Methods: The data used in this study were collected from a community-based dementia care center that was able to continue their dementia care services through a Tele-Health intervention program.

Trimethoprim-Sulfamethoxazole Versus Levofloxacin for Infections: A Retrospective Comparative Effectiveness Study of Electronic Health Records from 154 US Hospitals.

Background: Trimethoprim-sulfamethoxazole (TMP-SMX) is considered first-line therapy for infections based on observational data from small studies. Levofloxacin has emerged as a popular alternative due to tolerability concerns related to TMP-SMX. Data comparing levofloxacin to TMP-SMX as targeted therapy are lacking.

Feasibility of chondrogenesis for the entire umbilical cord in preliminary preparation for tracheal graft.

Background: There remains a scarcity of both autografts and allografts for tracheal transplantation after long-segmental resection. Subsequently, tissue engineering has become a promising alternative for tracheal transplantation, which requires successful chondrogenesis.

Methods: To optimize the protocol for chondrogenesis using the pig-derived whole Umbilical Cord (UC) as the starting material, it must be performed without using the UC-multipotent stromal cell (MSCs) isolation procedure.

Robotic or transanal total mesorectal excision (TaTME) approach for rectal cancer, how about both? Feasibility and outcomes from a single institution.

Laparoscopic surgery for rectal cancer is technically challenging. Robotic and transanal TME (TaTME) are both novel approaches developed to provide better visualization and dissection. We aim to combine both approaches in a hybrid procedure and evaluate the feasibility as well as patient and oncological outcomes in this study.

Extrapulmonary Nontuberculous Mycobacteria Infections in Hospitalized Patients, United States, 2009-2014.

Nontuberculous mycobacteria (NTM) cause pulmonary and extrapulmonary infections in susceptible persons. To characterize the epidemiology of skin and soft tissue (SST) and disseminated extrapulmonary infections caused by NTM in the United States, we used a large electronic health record database to examine clinical, demographic, and laboratory data for hospitalized patients with NTM isolated from extrapulmonary sources during 2009-2014. Using all unique inpatients as the denominator, we estimated prevalence and summarized cases by key characteristics.

Effectiveness of adjunctive clindamycin in β-lactam antibiotic-treated patients with invasive β-haemolytic streptococcal infections in US hospitals: a retrospective multicentre cohort study.

Background: Clindamycin is strongly recommended as an adjunctive treatment to β-lactam antibiotics in patients with severe invasive group A β-haemolytic streptococcal (iGAS) infections. However, there is little evidence of a benefit in the use of clindamycin in humans, and its role, if any, in treating patients with invasive non-group A/B β-haemolytic streptococcal (iNABS) infections is unclear.

Methods: For this retrospective multicentre cohort study, we used a dataset from patients in the Cerner Health Facts database, which contains electronic health-based data from 233 US hospitals.

Empyema thoracis complicated by anaemia as caused by occult bonelet aspiration.

A 62-year-old man was referred to our medical centre with productive cough and high fever over the span of one week, as well as the affiliated symptoms of chronic cough and dizziness for more than six months. Computed tomography (CT) of the thorax was performed and analysed revealing lobulated empyema with thick pleura and two foreign body (FB) retentions in the right lower lobe bronchus. The patient proceeded to thoracoscopic decortications and finalized through retrieval of two dark black stained bonelets with ignored aspiration.

Inappropriate empirical antibiotic therapy for bloodstream infections based on discordant in-vitro susceptibilities: a retrospective cohort analysis of prevalence, predictors, and mortality risk in US hospitals.

Background: The prevalence and effects of inappropriate empirical antibiotic therapy for bloodstream infections are unclear. We aimed to establish the population-level burden, predictors, and mortality risk of in-vitro susceptibility-discordant empirical antibiotic therapy among patients with bloodstream infections.

Methods: Our retrospective cohort analysis of electronic health record data from 131 hospitals in the USA included patients with suspected-and subsequently confirmed-bloodstream infections who were treated empirically with systemic antibiotics between Jan 1, 2005, and Dec 31, 2014.

Mycobacterial Testing Trends, United States, 2009-2015.

We studied 31 US healthcare facilities to characterize trends in mycobacterial testing. During 2009-2015, testing for acid-fast bacilli increased 3.2% annually, and prevalence of pathogenic nontuberculous mycobacteria increased 4.

Invasive Candidiasis Species Distribution and Trends, United States, 2009-2017.

Background: Invasive candidiasis (IC) is a growing concern among US healthcare facilities. A large-scale study evaluating incidence and trends of IC in the United States by species and body site is needed to understand the distribution of infection.

Methods: An electronic medical record database was used to calculate incidence and trends of IC in the United States by species and infection site from 2009 through 2017.
