Outcomes of surgical resection for pulmonary metastasis from pancreatic cancer.

Purpose: As the number of long-term survivors of pancreatic cancer is expected to increase thanks to recent advances in multidisciplinary treatment and earlier diagnoses of pancreatic cancer, we are likely to encounter more cases of postoperative pulmonary nodules. We analyzed the clinical course and prognosis of resection of pulmonary metastases from pancreatic cancer to clarify the prognostic implication of pulmonary metastasectomy for pancreatic cancer.

Method: We retrospectively analyzed 35 patients who underwent resection of lung metastases after pancreatic cancer surgery.

[A Case of Pancreatic Pseudocyst Recurrence after Surgery for Remnant Pancreatic Cancer].

The patient was a 72-year-old man with a history of pancreatic cancer and IPMA treated with distal pancreatectomy. He had recurrence-free period after adjuvant chemotherapy with S-1. But 6 years after the surgery, a diameter of 1 cm mass was noted in the remnant pancreas on MRI examination after hepatocellular carcinoma treatment.

Surgical treatment for non-tuberculous mycobacterial pulmonary disease: analysis of prognostic factors.

The surgical treatment for non-tuberculous mycobacterial pulmonary disease (NTM-PD) has an important adjunctive role and reported outcomes have been generally good; however, the prognostic factors remain unclear. Sixty-one patients with NTM-PD who underwent surgical resection for a therapeutic purpose from January 2000 to March 2017 at five affiliated institutions were enrolled. We explored the factors that influence complications and prognosis by retrospectively referring to the medical records.

Analysis of pulmonary nodules caused by nontuberculous mycobacteriosis in 101 resected cases: multi-center retrospective study.

Background: Solitary pulmonary nodules caused by nontuberculous mycobacteriosis are included as a category of pulmonary nontuberculous mycobacterium disease. Clinical characteristics, treatments and prognosis are not fully known because there are a few related reports.

Methods: This was a multi-center retrospective study of 101 cases diagnosed as solitary nodular type of nontuberculous mycobacteriosis from January 2000 to March 2017 that underwent resection at 9 related facilities belonging to the Thoracic Surgery Study Group of Osaka.

Long-Term Outcomes of Pulmonary Metastasectomy for Uterine Malignancies: A Multi-institutional Study in the Current Era.

Background: Information on pulmonary metastasectomy (PM) for uterine malignancies in the current era is limited. In the present study, we analyzed the clinical course and results of PM for uterine malignancies in the era of modern imaging diagnostics to clarify the role of PM in the current era in a multi-institutional setting.

Methods: Fifty-seven patients who underwent PM for uterine malignancies between 2006 and 2015 were retrospectively reviewed.

Cluster circulating tumor cells in surgical cases of lung cancer.

Objectives: A cancer lesion sheds tumor cells into the circulating blood as circulating tumor cells (CTCs). Since cluster CTCs have been considered as precursor lesions of metastasis, their clinical implication was investigated in this study according to the preoperative status of cluster CTC detection in surgical cases of clinically early-stage lung cancer.

Methods: Among 104 surgical patients of early-stage lung cancer, CTCs were extracted from the peripheral blood before surgery using a micro-pore size selection method (ScreenCell) and diagnosed microscopically.

Effect of Cardiac Expansion on Postsurgical Pulmonary Resection Recovery.

Background/aim: In patients undergoing lung resection, even when lung and ventricular function are normal, there may be a prolonged delay in postoperative recovery. The effect of left ventricular extension disorders on recovery after pulmonary resection was investigated.

Materials And Methods: The postoperative recovery of ninety patients with normal left ventricular ejection fraction and exercise tolerance who underwent anatomical pulmonary resection was evaluated according to the grade of left ventricular expansion (E/e').

Development of a Fried Frailty Phenotype Questionnaire for Use in Screening Community-Dwelling Older Adults.

Objectives: The aim of this study was to develop a Fried Frailty Phenotype Questionnaire (FFPQ) and a Japanese FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale (FRAIL-J) and to evaluate the reliability and validity of both questionnaires in Japanese community-dwelling older adults.

Design: Cross-sectional analysis of Itoshima Frail Study (IFS).

Setting: The IFS is an ongoing community-based prospective study in Itoshima (Japan).

Absorption, Distribution, Metabolism, and Excretion of the Novel Helicase-Primase Inhibitor, Amenamevir (ASP2151), in Rodents.

Background And Objectives: The helicase-primase inhibitor amenamevir (ASP2151) is a novel therapeutic agent which has been approved for the treatment of herpes zoster. The present study examined the pharmacokinetic profile of amenamevir in rodents and compared it with data from the literature of past and current established therapies (acyclovir and valaciclovir) to provide additional data to facilitate drug discovery and proper drug use.

Methods: In situ absorption, blood and plasma radioactivity concentrations, tissue distribution, and excretion were determined using liquid scintillation counting.

HER3 expression is enhanced during progression of lung adenocarcinoma without EGFR mutation from stage 0 to IA1.

Background: Activating EGFR mutations, HER2, and HER3 are implicated in lung cancer; however, with the exception of EGFR gene amplification in lung adenocarcinoma harboring EGFR mutations, their involvement in disease progression during the early stages is poorly understood. In this paper, we focused on which receptor is correlated with lung adenocarcinoma progression in the presence or absence of EGFR mutation from stage 0 to IA1.

Methods: HER2 and HER3 expression and activating EGFR mutations in surgically resected lung adenocarcinoma exhibiting ground glass nodules on chest computed tomography and re-classified to stage 0 and IA1 were examined by immunohistochemistry and peptide nucleic acid-locked nucleic acid PCR clamp method, respectively.

Solitary pulmonary nodules due to non-tuberculous mycobacteriosis among 28 resected cases.

Background: In some patients, non-tuberculous mycobacteria (NTM) infections manifest in solitary nodules (solitary nodular [SN] type) generally caused by Mycobacterium avium complex (MAC). In patients treated using surgical resection, the American Thoracic Society guidelines state that postoperative chemotherapy is not necessary in the absence of lesions, although there have been a few reports of such cases.

Methods: Twenty-eight patients diagnosed with NTM who underwent solitary pulmonary nodule resection at Toneyama Hospital, Osaka, Japan, between January 2000 and October 2012 were enrolled.

Colopleural fistula caused by aspergillus: an extremely rare complication after lung resection-case report.

A colopleural fistula is a rare condition reported to be caused by Crohn's disease, a malignant tumor of the gastrointestinal tract, and other clinical conditions. Some studies have noted that a sub-diaphragmatic abscess, usually organized following abdominal surgery, may play some role in the formation of this type of fistula. Therefore, a colopleural fistula is a complication very rarely encountered by thoracic surgeons after lung resection.

Cavernous hemangioma in the thymus: a case report.

Cavernous hemangioma is not a neoplasm, but rather a congenital venous malformation with the potential to develop in all parts of the body, though it is very rarely seen in the thymus. We report a case of cavernous hemangioma in the thymus partially resected. A 71-year-old woman presented with pericardial discomfort, and chest computed tomography (CT) showed a left lateral mediastinal mass which was 2.

Clinical effect of real time pulse rate monitoring with a portable pulsimeter on physical exercise therapy for male patients with type 2 diabetes.

In patients with type 2 diabetes, it is recommended that exercise therapy is performed using heart rate as an index of exercise intensity. This study was designed to clinically evaluate whether continuous exercise therapy with a portable pulsimeter for self-monitoring of the pulse rate influences glycemic control in patients with type 2 diabetes. We randomly assigned 23 male patients to a pulse displayed group (in which the portable pulsimeter displayed a pulse rate) or a pulse non-displayed group (in which the portable pulsimeter only recorded the data and did not display a pulse rate).

A Double-Blind Placebo-Controlled Study of the Effects of Olprinone, a Specific Phosphodiesterase III Inhibitor, for Preventing Postoperative Atrial Fibrillation in Patients Undergoing Pulmonary Resection for Lung Cancer.

Background: We previously reported that patients with elevated preoperative B-type natriuretic peptide (BNP) levels have an increased risk for postoperative atrial fibrillation following lung cancer surgery. The present study evaluated whether the specific phosphodiesterase III inhibitor olprinone can reduce the incidence of postoperative atrial fibrillation in patients with elevated BNP levels undergoing pulmonary resection for lung cancer.

Methods: A prospective randomized study was conducted with 40 patients who had elevated preoperative BNP levels (≥ 30 pg/mL) and underwent scheduled lung cancer surgery.

Absorption, distribution, metabolism and excretion of novel phosphodiesterase type 4 inhibitor ASP3258 in rats.

The potent and selective phosphodiesterase 4 inhibitor ASP3258 is a novel therapeutic agent for asthma and chronic obstructive pulmonary disease (COPD). After a single oral administration to rats, ASP3258 is rapidly absorbed with a bioavailability of 106%. In situ absorption data indicated that ASP3258 is mainly absorbed in the small intestine.

Lymphatic invasion of micropapillary cancer cells is associated with a poor prognosis of pathological stage IA lung adenocarcinomas.

The cancer cells of lung adenocarcinoma with a micropapillary pattern (MPP) have been found to frequently invade lymphatic vessels, and the prognosis of patients with lung adenocarcinoma with an MPP is poor. In the present study, the cancer cells of lung adenocarcinomas containing an MPP were found to express vimentin more extensively than those in lung adenocarcinoma without an MPP. The contribution of cancer cells in the MPP component to adenocarcinoma lymphatic invasion was assessed using vimentin as a marker.

Association of cigarette smoking with the expression of nuclear survivin in pathological Stage IA lung adenocarcinomas.

Survivin is expressed in the cytoplasm and/or nucleus of various types of malignant tumor cells. Cytoplasmic survivin functions as an apoptosis inhibitor, while nuclear survivin is indispensable for complete mitosis completion. To investigate the effect of cigarette smoking on the survivin expression in lung adenocarcinomas at the early developmental stage, we examined the expression of nuclear and cytoplasmic survivin in pathological Stage IA lung adenocarcinomas resected from 38 non-smokers and 44 smokers (current smokers and ex-smokers) using an immunohistochemical method.

Clinical predictor of pre- or minimally invasive pulmonary adenocarcinoma: possibility of sub-classification of clinical T1a.

Objectives: A new pathological classification for pre- and minimally invasive adenocarcinoma has been established, with distinction prior to surgery crucial because of the extremely good prognosis.

Methods: Of 412 patients who underwent surgery for lung cancer from 2008 to 2011, 110 classified as c-stage I had each of the following four parameters assessed for predictive power for pre- or minimally invasive adenocarcinoma and relapse-free survival (RFS): (i) whole tumour size (WS) shown by computed tomography (CT) , (ii) size of the solid (SS) component in CT findings, (iii) maximum standard uptake value in fluorodeoxyglucose positron emission tomography (FDG-PET)/CT scan images (SUVmax) and (iv) serum level of carcinoembryonic antigen.

Results: For prediction of pre- or minimally invasive adenocarcinoma, the area under the receiver-operating curve was >0.

We report a facile design method for constructing multiple-input and visible-output logic gates by combining signal-converting DNA machines and the gold nanoparticle aggregation-based foundational AND gate.

IL-6 amplifier activation in epithelial regions of bronchi after allogeneic lung transplantation.

The IL-6 amplifier, a positive feedback loop for NFκB signaling, which was originally found to be activated by IL-17A and IL-6 stimulation in non-immune cells, is molecularly a simultaneous activator of NFκB and signal transducer and activator of transcription 3 (STAT3), functionally a local chemokine inducer and pathologically a machinery for inflammation development. It has been shown that IL-6 amplifier activation in epithelial cells contributes to rejection responses in a mouse chronic rejection model that develops a bronchiolitis obliterans (BO)-like disease. We investigated whether the IL-6 amplifier is activated in BO regions of a human lung graft after allogeneic transplantation.

Ectopic cervical thymoma accompanied by Good's syndrome.

Ectopic cervical thymoma (ECT) is a rare tumor that is frequently misdiagnosed as a thyroid tumor or other malignancy. A 34-year-old male with a right palpable neck mass had been mistakenly diagnosed with T-cell lymphoblastic lymphoma even after an open biopsy. The atypical clinical course, including hypogammaglobulinemia, led us to the correct diagnosis; ECT accompanied by Good's syndrome (GS).
