In this study, we examined the minimum requirements for personal protective equipment with double surgical masks to potentially reduce unnecessary waste of supplies.

Methods: Two mannequins were each connected to a test lung machine simulating a surgeon and patient with spontaneous breathing.

Recommendations and guidelines for the treatment of infections due to multidrug resistant organisms.

Antimicrobial drug resistance is one of the major threats to global health. It has made common infections increasingly difficult or impossible to treat, and leads to higher medical costs, prolonged hospital stays and increased mortality. Infection rates due to multidrug-resistant organisms (MDRO) are increasing globally.

The impact of antimicrobial stewardship program designed to shorten antibiotics use on the incidence of resistant bacterial infections and mortality.

Reassessing the continuing need for and choice of antibiotics by using an antibiotic "time out'' program may reduce unnecessary treatment. This study aimed to explore the effect of an antibiotic stewardship program (ASP) on the antibiotics consumption, incidence of resistant bacterial infections and overall hospital mortality in a tertiary medical center during the study period 2012-2014. An ASP composed of multidisciplinary strategies including pre-prescription approval and post-approval feedback and audit, and a major "time out'' intervention (shorten the default antibiotic prescription duration) usage was introduced in year 2013.

Early clinical exposure improves medical students' recognition of the need for professionalism and interprofessional collaboration.

Background: Medical students in Taiwan start their clerkship in their fifth year. A lack of early clinical exposure can mean they have a lack of medical professionalism and collaborative practice. This study investigates whether early engagement in hospital-based clinical practice could improve their understanding of these requirements.

The epidemiology and etiologies of respiratory tract infection in Northern Taiwan during the early phase of coronavirus disease 2019 (COVID-19) outbreak.

Background: Coronavirus disease 2019 (COVID-19) manifests symptoms as common etiologies of respiratory tract infections (RTIs). During the pandemic of COVID-19, identifying the etiologies correctly from patients with RTI symptoms was crucial in not only disease control but preventing healthcare system from collapsing. By applying sensitive PCR-based molecular assays, we detected the etiologic agents and delineated the epidemiologic picture of RTIs in the early phase of COVID-19 pandemic.

Trios-OSCE-based simulation course enhances the subcompetency of emergency-stabilization for postgraduate year-1 residents.

Background: For patient safety, this study aims to evaluate the effectiveness of additional objective structured clinical examination (OSCE)-based medical simulation courses to establish the "emergency-stabilization" subcompetency of postgraduate first year (PGY-1) residents.

Methods: In the simulation course, trainees were randomly divided into three groups: intervention, regular, and control group as Trios-OSCE trainees, Single-OSCE trainees, or OSCE observers (feedback-givers) after attending the pre-OSCE common simulation workshop. Three PGY-1 residents rotated through the Trios OSCE long-station together, while single PGY-1 residents rotated through regular OSCE alone and the control group gave feedback after observation of their peers' OSCE performance.

Endotoxemia-enhanced renal vascular reactivity to endothelin-1 in cirrhotic rats.

Hepatorenal syndrome (HRS), a severe complication of advanced cirrhosis, is defined as hypoperfusion of kidneys resulting from intense renal vasoconstriction in response to generalized systemic arterial vasodilatation. Nevertheless, the mechanisms have been barely investigated. Cumulative studies demonstrated renal vasodilatation in portal hypertensive and compensated cirrhotic rats.

Risk factors and characteristics of blood stream infections in patients with newly diagnosed multiple myeloma.

Background: Patients with multiple myeloma are generally immune-compromised either due to pronounced depression in primary antibody responses or because of anti-myeloma therapy. Infection is a major risk factor for early deaths among these patients. The impact of blood stream infections (BSI) on newly diagnosed myeloma patients has been less studied.

Difference in imipenem, meropenem, sulbactam, and colistin nonsusceptibility trends among three phenotypically undifferentiated Acinetobacter baumannii complex in a medical center in Taiwan, 1997-2007.

Background: To determine whether the susceptibilities and the trends of nonsusceptibility of imipenem, meropenem, sulbactam, and colistin differed among Acinetobacter baumannii, Acinetobacter genomic species 3 (AGS 3), and Acinetobacter genomic species 13TU (AGS 13TU) over 11 years.

Methods: A total of 1,039 nonduplicate blood isolates of A baumannii complex from bacteremic patients between 1997 and 2007 were collected at Taipei Veterans General Hospital and were identified to the species level using a multiplex polymerase chain reaction method and sequence analysis of 16S-23S intergenic spacer. The minimal inhibitory concentrations of antibiotics were determined by the agar dilution method.

Does radiographic evidence of prior pulmonary tubercular infection influence the choice of empiric antibiotics for community-acquired pneumonia in a tuberculosis-endemic area?

Background/purpose: Recent medical literature suggests that use of fluoroquinolones (FQs) might be associated with the delayed diagnosis of pulmonary tuberculosis (TB). The purpose of this study was to assess the impact of radiographic evidence of prior pulmonary TB infection on empiric antibiotic choice in cases of community-acquired pneumonia (CAP), as well as the effect of antibiotic regimens on clinical outcome.

Methods: A total of 280 patients with CAP between 1 May and 31 December 2007 were included in the study and their medical records were retrospectively reviewed.

Severe extensive bone marrow necrosis from miliary tuberculosis without granulomas and pulmonary presentations.

Bone marrow necrosis (BMN) is a rare clinicopathologic entity caused by hypoxemia after failure of the microcirculation, which frequently manifests with bone pain, fever, and peripheral cytopenia. In most reported cases of BMN resulting from miliary tuberculosis (TB), the presence of marrow granulomas, pulmonary infiltrates and/or extrapulmonary involvement is common. We report a female patient with extensive BMN from miliary TB, whose initial presentation was only severe peripheral cytopenia with extensive marrow necrosis, with neither evident pulmonary manifestations nor granulomas in the marrow biopsy.
