Reduction in the need for surgery and mortality after early administration of fibrinolytics following empyema drainage.

Objectives: Although intrapleural administration of fibrinolytics is an important treatment option for the management of empyema, the addition of fibrinolytics failed to reduce the need for surgery and mortality in previous randomized controlled trials. This study aimed to investigate the effects of administrating fibrinolytics in the early phase (within 3 days of chest tube insertion) of empyema compared with late administration or no administration.

Methods: We used the Japanese Diagnosis Procedure Combination Inpatient Database to identify patients aged ≥16 years who were hospitalized and underwent chest tube drainage for empyema.

Anti-Inflammatory Effects of Japanese Herbal Medicine Hochuekkito in a Mouse Model of Acute Exacerbation of Chronic Obstructive Pulmonary Disease.

Introduction: The traditional Japanese herbal medicine hochuekkito (TJ-41) has been reported to ameliorate systemic inflammation and malnutrition in patients with chronic obstructive pulmonary disease (COPD). TJ-41 has also been known to have preventive effects against influenza virus infection. However, its role in the acute exacerbation of COPD (AECOPD) remains to be elucidated.

The Link between Periodontal Disease and Asthma: How Do These Two Diseases Affect Each Other?

A growing body of evidence suggests that the effects of poor oral hygiene extend beyond the oral cavity and are associated with a variety of systemic diseases, including asthma. Asthma, which results in symptoms of cough, wheezing, and dyspnoea, and is characterized by airflow limitation with variability and (partial or complete) reversibility, is amongst the most prevalent respiratory diseases with approximately 262 million patients worldwide, and its prevalence and disease burden is on the increase. While asthma can occur at a young age, it can also develop later in life and affects a variety of age groups.

Effectiveness and safety of the co-administration of Yokukan-San (Japanese herbal medicine) with antipsychotics in hospitalized older patients with pneumonia.

Aim: Behavioral and psychological symptoms and delirium frequently occur in hospitalized older patients with pneumonia and are associated with longer hospital stays. Yokukan-San (YKS, traditional Japanese [Kampo] medicine) and antipsychotics are often used to treat delirium and behavioral and psychological symptoms in Japan. Hence, this study aimed to assess the effectiveness and safety of the co-administration of YKS with atypical antipsychotics in older patients with pneumonia.

Putative Bidirectionality of Chronic Obstructive Pulmonary Disease and Periodontal Disease: A Review of the Literature.

The prevalence of chronic obstructive pulmonary disease (COPD) is increasing worldwide and is currently the third leading cause of death globally. The long-term inhalation of toxic substances, mainly cigarette smoke, deteriorates pulmonary function over time, resulting in the development of COPD in adulthood. Periodontal disease is an inflammatory condition that affects most adults and is caused by the bacteria within dental plaque.

Alectinib-induced Hemolytic Anemia with Positive Direct Antiglobulin Test in a Patient with Lung Adenocarcinoma: A Possible Drug-drug Interaction Effect.

Recent studies have reported that direct antiglobulin test (DAT) results were negative in cases of alectinib-induced hemolytic anemia with abnormal red blood cell (RBC) morphology. We herein report the case of a 72-year-old female patient who was diagnosed with alectinib-induced hemolytic anemia who - in contrast to previous reports - showed a positive DAT result. After discontinuing famotidine and alectinib, the DAT results turned negative; however, when alectinib was resumed, hemolysis recurred.

Association between Inhalation Instruction Method in Community Pharmacies and Inhaler Device Handling Error in Patients with Obstructive Lung Disease: An Evaluation of the Impact of Practical Demonstration by Pharmacists.

Inhaler devices play an important role in the management of obstructive lung diseases including asthma, chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap. Some of these patients show suboptimal inhaler techniques; however, time for inhaler instruction by pharmacists is limited in daily clinical practice. Therefore, sufficient education regarding inhaler device handling should be provided within a limited time frame.

Association between comprehensive geriatric assessment and polypharmacy at discharge in patients with ischaemic stroke: A nationwide, retrospective, cohort study.

Background: Polypharmacy and its adverse drug events are a major healthcare challenge related to falls, hospitalisations and mortality. Comprehensive geriatric assessment (CGA) may contribute to polypharmacy improvement, however, there is no clear evidence so far.

Methods: Using a national inpatient database in Japan from April 1, 2014 to March 31, 2018, we investigated the association between CGA and polypharmacy.

Association between protein intake and mortality in older patients receiving parenteral nutrition: a retrospective observational study.

Background: Malnutrition of inpatients is often overlooked and remains a serious concern. However, there are few studies on the relations between infused energy and amino acid intakes and clinical outcomes in older patients on parenteral nutrition.

Objectives: We aimed to determine the short-term outcomes of infused energy and amino acid intakes in older patients receiving parenteral nutrition.

Pulmonary disease as a risk factor for transfusion-related acute lung injury.

Transfusion-related acute lung injury (TRALI) is a severe condition characterised by noncardiogenic pulmonary oedema that develops within 6 h of blood transfusion. Patient factors and blood products have both been implicated in the development of TRALI; however, the role of pulmonary disease has not been investigated. We aimed to determine whether pulmonary disease is a risk factor for TRALI.

Multiple cerebral infarctions in -rearranged lung adenocarcinoma.

Rearrangements of specific tyrosine kinases are associated with an elevated risk of venous thrombosis in lung adenocarcinoma, although their effects on arterial thrombosis have not been fully elucidated. Here, we report two cases of ROS proto-oncogene 1 ()-rearranged lung adenocarcinoma with cerebral infarction during the peri-diagnostic period. Two cases took contrasting clinical courses: one patient could not receive targeted therapy because of a significant decline in performance status, whereas in the other patient, the performance status was maintained and targeted therapy drastically reduced the tumour size.

Factors affecting in-hospital mortality of non-tuberculous mycobacterial pulmonary disease.

Background: The incidence and prevalence of non-tuberculous mycobacterial pulmonary disease (NTM-PD) are reportedly increasing in many parts of the world. However, there are few published data on NTM-PD-related death. Using data from a national inpatient database in Japan, we aimed in this study to identify the characteristics of patients with NTM-PD and clinical deterioration and to identify risk factors for in-hospital mortality.

Alpha-Fetoprotein-Producing Lung Hepatoid Adenocarcinoma with Brain Metastasis Treated with S-1.

Lung hepatoid adenocarcinoma (HAC) is a rare primary lung carcinoma pathologically characterized by hepatocellular carcinoma-like tumor cells, the majority of which produce alpha-fetoprotein (AFP). The clinical prognosis of lung HAC is generally poor, and effective therapeutic regimens for inoperable or recurrent cases have not been established. Here, we report a case of AFP-producing lung HAC with brain metastasis with long-term disease control, treated with the 5-fluorouracil-derived regimen S-1.

The Japanese Herbal (Kampo) Medicine Hochuekkito Attenuates Lung Inflammation in Lung Emphysema.

Chronic obstructive pulmonary disease (COPD) is a systemic inflammatory disorder. It often causes weight loss, which is considered a poor prognostic factor. A Japanese herbal Kampo medicine, Hochuekkito (TJ-41), has been reported to prevent systemic inflammation and weight loss in COPD patients, but the underlying biological mechanisms remain unknown.

Interleukin-5-producing malignant pleural mesothelioma with eosinophilic pleural effusion.

Malignant tumors are often associated with eosinophilic pleural effusion. Here, we encountered a case of interleukin-5 (IL-5)-producing malignant pleural mesothelioma with eosinophilic pleural effusion. The patient was a 50-year-old male.

Association between comprehensive geriatric assessment and short-term outcomes among older adult patients with stroke: A nationwide retrospective cohort study using propensity score and instrumental variable methods.

Background: Comprehensive geriatric assessment (CGA) is a multidimensional and multidisciplinary method to identify geriatric conditions among older patients. The aim of the present study was to examine the associations between CGA and short-term outcomes among older adult inpatients with stroke.

Methods: The study was a nationwide, retrospective cohort study.

Naftopidil reduced the proliferation of lung fibroblasts and bleomycin-induced lung fibrosis in mice.

Naftopidil, an α-1 adrenoceptor antagonist with few adverse effects, is prescribed for prostate hyperplasia. Naftopidil inhibits prostate fibroblast proliferation; however, its effects on lung fibroblasts and fibrosis remain largely unknown. Two normal and one idiopathic pulmonary fibrosis human lung fibroblast lines were cultured with various naftopidil concentrations with or without phenoxybenzamine, an irreversible α-1 adrenoceptor inhibitor.

Goodpasture's disease in a patient with advanced lung cancer treated with nivolumab: An autopsy case report.

Nivolumab, an anti-programmed death-1 immune checkpoint inhibitor (ICI), is now widely used to treat numerous cancers. Although most adverse effects related to ICIs are controllable, fulminant immune-related adverse events can occur. A 74-year-old patient with non-small-cell lung cancer was treated with nivolumab as a second-line treatment.

Acute Arterial Thrombosis during Postoperative Adjuvant Cisplatin-based Chemotherapy for Completely Resected Lung Adenocarcinoma.

A malignant tumor can cause hypercoagulation and it also often coexists with thrombosis. Cisplatin-based chemotherapy can also induce adverse vascular effects, including arterial thrombosis. We herein report a case of acute arterial thrombosis in a patient undergoing postoperative adjuvant cisplatin-based chemotherapy for completely resected lung cancer.

Cytological findings of ROS1-rearranged lung adenocarcinoma.

ROS1-rearranged lung adenocarcinoma has been recently identified. We report a case of ROS1-rearranged lung adenocarcinoma with special emphasis on cytological findings. Here, we report a case of young woman with ROS1-rearranged lung adenocarcinoma diagnosed by cytology and discuss the clinical, cytological, and molecular findings.
