In tuberculosis (TB), chest radiography (CXR) patterns are highly variable, mimicking pneumonia and many other diseases. This study aims to evaluate the efficacy of Google teachable machine, a deep neural network-based image classification tool, to develop algorithm for predicting TB probability of CXRs. The training dataset included 348 TB CXRs and 3806 normal CXRs for training TB detection.

Here, we compared the effectiveness of transplantation of human mesenchymal stem cells from umbilical cord Wharton's jelly (HUMSCs) versus those from adipose tissue (ADMSCs) in reversing pulmonary fibrosis in rats.

Objective: To assess the link between () infection and the incidence of SLE.
Method: We conducted a retrospective cohort study, which identified 116,043 hospitalized patients with between 2000 and 2012 from the Taiwan National Health Insurance Research Database and compared them with 447,839 matched inpatients who had never been diagnosed with infection (at a 1:4 ratio, matched by age, gender, and index year).
Chronic obstructive pulmonary disease (COPD) has significant contributions to morbidity and mortality world-wide. Early symptoms of COPD are not readily distinguishable, resulting in a low rate of diagnosis and intervention. Different guidelines and recommendatations for the diagnosis and treatment of COPD exist globally.

Methods: We conducted a 13-year nationwide, population-based, retrospective cohort study to examine the association between the history of gout and risk of glaucoma by using the Longitudinal Health Insurance Database (LHID) of Taiwan. The gout cohort included 52 943 patients with newly diagnosed gout who were recruited between 2000 and 2012.
Background: The present study compared the effects of antifibrotic medications, pirfenidone, and nintedanib, with transplantation of human umbilical mesenchymal stem cells (HUMSCs) in restoring rat pulmonary fibrosis (PF).
Methods: A stable animal model was established via an intratracheal injection of 5 mg bleomycin (BLM). One single transplantation of 2.
Patients in critical care medicine are ageing. There is limited literature evaluating long-term outcomes and prognostic factors for the growing number of elderly patients with acute respiratory failure (ARF) receiving invasive mechanical ventilation (IMV). Data on elderly patients (≧ 65 years old) with ARF receiving intubation and IMV during 2003-2012 were retrospectively collected from the national health database in Taiwan.

It is unclear whether long-acting β2-agonist (LABA)/LAMA fixed-dose combinations (FDCs) are more effective than LAMAs alone in preventing exacerbations. The aim of this study was to systematically review the literature to investigate whether LABA/LAMA FDCs are more effective than LAMA monotherapy in preventing exacerbations.

The study identified 22,440 patients who received a diagnosis of IDA between 2000 and 2012 from a random sample of 1 million people from Taiwans National Health Insurance Research Database. The patients with IDA were randomly matched with 89,528 patients with no IDA by age, gender, and index year.

However, the clinical features and outcomes of IPF in Taiwan have not been well studied. In addition, the survival difference between patients with IPF alone and combined pulmonary fibrosis and emphysema (CPFE) remains controversial.

Successful recovery from PF requires inhibiting inflammation, promoting collagen degradation and stimulating alveolar regeneration. Human umbilical mesenchymal stem cells (HUMSCs) not only regulate immune responses but also synthesize and release hyaluronan to improve lung regeneration.
View Article and Find Full Text PDFBackground: Iron deficiency is associated with decreased cellular immunity, which may predispose patients with iron deficiency anemia (IDA) to increased risk of developing tuberculosis (TB). This study investigated the relationship between newly diagnosed IDA and TB infection in Taiwan.
Methods: The study included data on 21,946 patients with incident IDA and 87,555 non-IDA controls from a national database covering the period 2000-2012.
This study aimed to investigate the relationship between Mycoplasma pneumonia (MP) infection and new development of ankylosing spondylitis (AS).Using data from the Taiwan National Health Insurance Research Database, we included a total of 116,084 patients with newly diagnosed MP between 2000 and 2012. The control cohort consisted of patients who did not have MP, matched 1:4 by age, sex, and index year.

In this study, we investigated the relationship between scrub typhus and systemic autoimmune diseases. We enrolled 6,928 hospitalized patients with scrub typhus between 2000 and 2012 from the Taiwan National Health Insurance Research Database, and we compared them with 27,712 selected inpatients who had never been diagnosed with scrub typhus (1:4 ratio, matched by age, sex, and index year) in relation to the risk of developing autoimmune diseases.

However, clinical evidence for this association is lacking. Therefore, this study aimed to provide epidemiologic evidence to clarify the relationship between MP and development of RA.

We present a case of a 64-year-old man with advanced small cell lung cancer (SCLC) treated with chemo-radiotherapy who attained partial remission initially but had disease progression to bulky cardiac metastasis and significant pericardial effusion. Severe heart failure with hepatic failure was found.

Two months after OVX, the rats gained weight and had a decreased serum estradiol level . Both micro-computed tomography (micro-CT) and histochemical analyses revealed a marked decrease in the bone volume (BV) and collagen content within the head, neck, and distal condyle of the femur, indicating that the osteoporosis animal model was successfully established 2 mo after bilateral OVX.

The pulmonary manifestation of this disease is highly variable and may mimic lung cancer, pneumonia, interstitial lung disease (ILD), sarcoidosis, and so forth. Small airway disease is rarely reported in IgG4-related lung disease (IgG4-RLD).

However, the initial choice of therapy is still uncertain. The aim of this study was to examine the clinical efficacy and safety of long-acting muscarinic antagonist (LAMA) and long-acting beta2-agonist (LABA) in patients with stable COPD.

Methods And Results: Echocardiography was performed in 141 patients with acute decompensated congestive HF and LV ejection fraction <35%, including 42 with permanent AF. The LA expansion index was calculated as (Volmax - Volmin) × 100%/Volmin, where Volmax was defined as maximal and Volmin as minimal LA volume.
Extramedullary hematopoiesis (EMH) is a compensatory response to many chronic anemic disorders. Intrathoracic EMH, usually presenting as paravertebral masses over the posterior mediastinum, is a rare entity and is usually asymptomatic. Hemothorax is a rare but possibly fatal complication.

The aim of this study was to compare the difference in the sedation of mechanically ventilated patients undergoing flexible bronchoscopy (FB) monitored by auditory-evoked potentials (AEPs) or the Ramsay sedation scale (RSS).
Methods: In a prospective, randomized, controlled study, all patients who underwent FB with propofol sedation were monitored and their sedation adjusted.
