Randomized Phase III Study of Docetaxel Plus Cisplatin Versus Pemetrexed Plus Cisplatin as First-line Treatment of Nonsquamous Non-Small-cell Lung Cancer: A TRAIL Trial.

Introduction: To date, no prospective phase III trials have directly compared the efficacy of pemetrexed plus cisplatin (Pem-Cis) with docetaxel plus cisplatin (Doc-Cis) in patients with nonsquamous non-small-cell lung cancer.

Materials And Methods: A total of 148 chemotherapy-naive patients lacking driver mutations were randomized into 21-day regimens of cisplatin 70 mg/m with either docetaxel 60 mg/m (n = 71) or pemetrexed 500 mg/m (n = 77) for ≤ 4 cycles. The primary objective was to assess the noninferiority of progression-free survival (PFS) for patients receiving the Doc-Cis regimen.

Polymeric LabChip real-time PCR as a point-of-care-potential diagnostic tool for rapid detection of influenza A/H1N1 virus in human clinical specimens.

It is clinically important to be able to detect influenza A/H1N1 virus using a fast, portable, and accurate system that has high specificity and sensitivity. To achieve this goal, it is necessary to develop a highly specific primer set that recognizes only influenza A viral genes and a rapid real-time PCR system that can detect even a single copy of the viral gene. In this study, we developed and validated a novel fluidic chip-type real-time PCR (LabChip real-time PCR) system that is sensitive and specific for the detection of influenza A/H1N1, including the pandemic influenza strain A/H1N1 of 2009.

Increase in serum haptoglobin and apolipoprotein M in patients with obstructive sleep apnoea.

Obstructive sleep apnoea (OSA) is a common syndrome, which is associated with a number of medical problems that impact morbidity and mortality. Although the precise mechanisms that underlie these associations are not fully understood, previous studies have suggested that patients with OSA show elevations of several biomarkers that are associated with cardiovascular risk. This study was undertaken to identify serum proteins associated with OSA by using a proteomics technique and to examine changes in identified protein levels after continuous positive airway pressure treatment.

Lung cancer patients who are asymptomatic at diagnosis show favorable prognosis: a korean Lung Cancer Registry Study.

Purpose And Methods: The outcomes of lung cancer patients who were asymptomatic at diagnosis have never been reported as part of a large-scale study. A national survey of lung cancer in South Korea registered a total of 8788 patients diagnosed in 2005. We report the results herein, with an emphasis on the prognosis of the asymptomatic lung cancer patients.

Association of snoring with chronic bronchitis.

Background: Snoring is more prevalent in patients with chronic bronchitis than in persons without it. Few studies have examined the effect of snoring on chronic bronchitis. We prospectively investigated the association between snoring and the incidence of chronic bronchitis.

Aspiration pneumonia due to polyethylene glycol-electrolyte solution (Golytely) treated by bronchoalveolar lavage.

Polyethylene glycol (PEG)-electrolyte solution (Golytely), is most commonly used for bowel preparation before colonoscopy, as well as for barium enema and colon surgery. In this case, a 70-year-old man developed ARDS following the administration of Golytely by mouth before a scheduled colonoscopy. Aspiration of PEG-electrolyte solution was suspected, and the patient was successfully treated by BAL.

Clinical characteristics of acute pulmonary thromboembolism in Korea.

Background: Acute pulmonary thromboembolism (APTE) remains an important cause of morbidity and mortality in Western countries. In Korea, both the incidence and the mortality rate of APTE were thought to be low compared to Western countries. We performed the present study to investigate the current status of APTE in Korea.

Association of habitual snoring with glucose and insulin metabolism in nonobese Korean adult men.

Habitual snoring is associated with cardiovascular morbidity and mortality, and metabolic abnormalities such as impaired glucose homeostasis. Many studies were performed in obese Western populations. The purpose of this study was to examine the association of habitual snoring with glucose and insulin metabolism in nonobese Korean men who were free of diabetes and hypertension.

Relation of epidermal growth factor receptor expression to mucus hypersecretion in diffuse panbronchiolitis.

Study Object: Diffuse panbronchiolitis (DPB) is a hypersecretory airway disease, and the mechanism of mucus hypersecretion in DPB is poorly understood. Moreover, mucin synthesis in the airways has been reported to be regulated by neutrophilic inflammation-induced epidermal growth factor receptor (EGFR) expression, and the degranulation of goblet cells is known to be mediated by neutrophilic elastase. In this study, we examined the relationship between EGFR expression in the bronchiolar epithelium with neutrophilic inflammation and mucus hypersecretion in the tissues of DPB patients.

Prevalence of sleep-disordered breathing in middle-aged Korean men and women.

With many epidemiologic studies made to establish the prevalence of sleep-disordered breathing (SDB) and obstructive sleep apnea syndrome (OSAS) in Western countries, no such data have been reported in Korea. The purpose of this study was to examine the prevalence of SDB and OSAS, and their related factors in Korean adults aged 40-69 years. Among the total of 5,020 participants at the baseline examination of the Korean Health and Genome Study, a random sample of 457 men and women was studied with employment of overnight full polysomnography to determine the prevalence of SDB and OSAS.

Chromosomal aberrations in Korean nonsmall cell lung carcinomas: degenerate oligonucleotide primed polymerase chain reaction comparative genomic hybridization studies.

Chromosomal aberrations were investigated in 48 Korean nonsmall cell carcinomas of the lung (NSCLC), by degenerate oligonucleotide primed polymerase chain reaction comparative genomic hybridization. These included 16 adenocarcinomas, 27 squamous cell carcinomas (SCCs), and 5 large-cell carcinomas. The common sites of copy number increases were 3q26 approximately qter (23 cases, 48%); 8q23 approximately qter (46%); 20q13.
