Impairment of Social-Related Quality of Life in COVID-19 Pneumonia Survivors: A Prospective Longitudinal Study.

The post-acute sequelae of SARS-CoV-2 (PASC) pose a threat to patients' health-related quality of life (HRQOL). Here, the impact of COVID-19 on HRQOL and the clinical factors associated with impaired HRQOL were examined. Discharged COVID-19 patients were assessed at 3 and 6 months after disease onset.

Clinicoradiological course of abemaciclib-induced pneumonitis with histology findings.

A woman in her late 40s presented with multiple abnormal shadows on high-resolution CT (HRCT), was treated with abemaciclib for recurrent right breast cancer post-surgery and chemoradiation therapy. During the 10-month chemotherapy, HRCT revealed a recurrent pattern of a partly appearing and disappearing organising pneumonia pattern without clinical symptoms. Bronchoalveolar lavage analysis revealed lymphocytosis, while transbronchial lung biopsy revealed alveolitis with epithelial cell injury.

[A CASE OF BIRD-RELATED HYPERSENSITIVITY PNEUMONITIS THAT DEVELOPED IN SUBACUTE COURSE AND PRESENTED WITH ACUTE FINDINGS].

A 52-year-old woman presented to a clinic in late August with exacerbated fatigue and dyspnea on exertion for several months. Then, she was referred and admitted to our hospital in late September. Her chest CT showed bilateral diffuse centrilobular micronodules.

Effect of dental intervention on improvements in metabolic syndrome patients: a randomized controlled clinical trial.

Background: Metabolic syndrome (MetS), caused by the accumulation of visceral fat, is considered a major cause of cardiovascular disease. This randomized controlled trial aimed to clarify the effect of dental intervention, including prosthodontics and/or periodontal treatment, combined with dietary and exercise guidance on MetS.

Methods: In total, 112 patients who met the Japanese waist circumference criteria of MetS were recruited.

[A CASE OF SUMMER-TYPE HYPERSENSITIVITY PNEUMONITIS ACCOMPANIED BY THE SYNDROME OF INAPPROPRIATE SECRETION OF ANTIDIURETIC HORMONE].

A 47-year old man presented to our hospital with a 6-month history of malaise, cough and dyspnea on exertion. Laboratory testing revealed the severe hyponatremia. A chest X-ray showed bilateral diffuse micronodules.

[FAMILIAL SUMMER-TYPE HYPERSENSITIVITY PNEUMONITIS INDUCED IN SUMMER AND WINTER AT THE WORK PLACE].

We report two family members, a 64-year-old woman (patient 1) and her 37-year-old son (patient 2) diagnosed with summer-type hypersensitivity pneumonitis (SHP). Both patients had high serum titers of anti-Trichosporon asahii antibody. The patients lived in the same house and worked in the same barbershop.

Synthetic double-stranded RNA enhances airway inflammation and remodelling in a rat model of asthma.

Respiratory viral infections are frequently associated with exacerbations of asthma. Double-stranded RNA (dsRNA) produced during viral infections may be one of the stimuli for exacerbation. We aimed to assess the potential effect of dsRNA on certain aspects of chronic asthma through the administration of polyinosine-polycytidylic acid (poly I:C), synthetic dsRNA, to a rat model of asthma.

Clinical features of the 2009 swine-origin influenza A (H1N1) outbreak in Japan.

To clarify the clinical symptoms of the influenza A virus during the 2009 pandemic influenza outbreak, we describe the clinical features of outpatients diagnosed with type A influenza by use of the rapid influenza diagnostic test (RIDT) from September to December 2009. Questionnaires were used to collect prospective data on 1,122 cases with influenza-like illness at our medical institutions. The independent predictors of influenza A virus were identified on the basis of demographic features and the clinical symptoms of the patients who tested positive for influenza A virus in the RIDT test.

RANTES expression induced by Toll-like receptor 4 ligand in rat airway smooth muscle cells.

Airway smooth muscle cells (ASMCs) have been reported to express Toll-like receptors (TLRs) and take part in the pathogenesis of asthma exacerbation. Though TLRs were found to activate epidermal growth factor receptor (EGFR) in airway epithelial cells, little is known about the association of TLR ligands with EGFR signaling pathways in ASMCs. Using primary cultured ASMCs from Brown Norway rats, TLR4, eotaxin, and RANTES mRNA were examined by real-time quantitative RT-PCR after stimulation with the TLR4 ligand, lipopolysaccharides (LPS).

Nonspecific interstitial pneumonia (NSIP) associated with anti-KS antibody: differentiation from idiopathic NSIP.

We report two cases of biopsy-proven nonspecific interstitial pneumonia (NSIP) with anti-KS (asparaginyl-tRNA) antibody. Anti-KS antibody is the sixth anti-aminoacyl-tRNA synthetase (ARS) antibody. They showed interstitial pneumonia without clinical symptoms, and high resolution computed tomography (HRCT) of the chest demonstrated consolidation along bronchovascular bundles and volume loss in the bilateral lower lobes, which were suggestive of connective tissue diseases (CTD).

Amiodarone pulmonary toxicity: a patient with three recurrences of pulmonary toxicity and consideration of the probable risk for relapse.

A 44-year-old man was treated with amiodarone for dilated cardiomyopathy. After 53 months, he developed amiodarone-induced interstitial pneumonia. Amiodarone treatment was terminated, and the patient was given corticosteroids.
