Usefulness of Transbronchial Lung Cryobiopsy When Starting Antifibrotic Treatment and Predicting Progressive Fibrosing Interstitial Lung Disease: Descriptive Research.

Background: Although transbronchial lung cryobiopsy (TBLC) is widely used in diagnostic algorithms for various interstitial lung diseases (ILDs), its real-world utility in the therapeutic decision-making strategy for ILD patients remains unclear, in particular, when judging the time to start antifibrotic agents.

Methods: We analyzed medical records of 40 consecutive patients with idiopathic or fibrotic hypersensitivity pneumonitis who underwent TBLC. A TBLC-based usual interstitial pneumonia (UIP) score was used to assess three morphologic descriptors: patchy fibrosis, fibroblastic foci, and honeycombing.

Body weight loss is a simple and useful indicator of prognosis and predictive tolerability in the first year of nintedanib therapy in patients with interstitial lung disease.

Background: Nintedanib is generally safe and well tolerated and can improve prognosis in patients with various interstitial lung diseases (ILDs). Appropriate management of adverse events of nintedanib is important to ensure its long-term persistent use. Weight loss is a routinely assessed adverse event in clinical practice.

Second-line immunosuppressant administration for steroid-refractory immune-related adverse events in patients with lung cancer.

Background: Evidence for use of second-line immunosuppressants for immune-related adverse events (irAEs) is inadequate. Therefore, a multicenter analysis should assess the efficacy of second-line immunosuppressants for severe irAEs associated with different malignant diseases.

Methods: This descriptive study aims to investigate the effects of second-line immunosuppressants on corticosteroid-refractory irAEs in patients with lung cancer.

Clinical significance of para-carinal air cysts in patients with pleuroparenchymal fibroelastosis: The relationship with pneumomediastinum and pneumothorax.

Background: Para-tracheal or para-carinal air cysts (PACs) are often asymptomatic and usually detected incidentally by methods such as computed tomography. Their clinical significance is unclear in patients with pleuroparenchymal fibroelastosis (PPFE).

Methods: We evaluated the clinical significance of PACs in PPFE and their relationship with pneumomediastinum or pneumothorax.

Can transbronchial lung cryobiopsy benefit adaptive treatment strategies in connective tissue disease-associated interstitial lung disease?

Background: Some patients with connective tissue disease (CTD)-associated interstitial lung disease (ILD) progress to pulmonary fibrosis over their disease course despite initial improvement, potentially indicating a poor prognosis. Transbronchial lung cryobiopsy (TBLC) is a new bioptic approach used in diffuse parenchymal lung diseases. This study of CTD-ILD assessed the utility of TBLC in determining therapeutic decision-making strategies.

Multicentre real-world data of ramucirumab plus docetaxel after combined platinum-based chemotherapy with programmed death-1 blockade in advanced non-small cell lung cancer: NEJ051 (REACTIVE study).

Background: Ramucirumab plus docetaxel (RD) is a promising treatment for previously treated advanced non-small cell lung cancer (NSCLC). However, its clinical significance after platinum-based chemotherapy plus programmed death-1 (PD-1) blockade remains unclear.

Research Question: What is the clinical significance of RD as a second-line treatment after the failure of chemo-immunotherapy in NSCLC?

Study Design And Methods: In this multicentre retrospective study, 288 patients with advanced NSCLC who received RDas second-line therapy after platinum-based chemotherapy plus PD-1 blockade, at 62 Japanese institutions from January 2017 to August 2020, were included.

Successful surgical treatment of epithelioid hemangioendothelioma involving multiple liver lesions and bilateral lung nodules.

Epithelioid hemangioendothelioma (EHE) affects many organs, particularly lung and liver, and typically presents as multiple lesions. Treatment for EHE is not yet standardized, but surgery is appropriate when lesions are resectable. In our patient, radiography revealed multiple bilateral pulmonary nodules, and CT showed several liver tumors.

Patient background and prognosis of chronic pulmonary aspergillosis in fibrosing interstitial lung disease.

Several previous reports have shown interstitial lung disease (ILD) to be a predictor of poor prognosis in patients with chronic pulmonary aspergillosis (CPA). However, there is a lack of clarity regarding patient background and the prognostic factors in CPA associated with ILD (CPA-ILD). Therefore, we assessed these points to obtain valuable information for clinical practice.

Impact of progressive fibrosing interstitial lung disease (ILD) in ILD patients complicated with secondary spontaneous pneumothorax.

Background: Secondary spontaneous pneumothorax (SSP) in interstitial lung disease (ILD) may influence prognosis of any ILD, and SSP onset predicts poor outcome in idiopathic pulmonary fibrosis (IPF). Recently, progressive fibrosing ILD (PF-ILD) has rapidly acquired importance.

Objective: We hypothesized that PF-ILD would strongly influence the prognosis of patients with any ILD complicated with SSP.

The role of first-trimester ultrasound screening for women with positive noninvasive prenatal testing results.

Aim: This study aimed to assess the utility of ultrasound screening for pregnancies with positive noninvasive prenatal testing results for trisomy 21, trisomy 18, and trisomy 13.

Methods: We performed a retrospective analysis of positive noninvasive prenatal testing results and first-trimester ultrasound screening at our department between 2013 and 2019. Invasive genetic testing was performed if the patient had positive noninvasive prenatal testing results.

Delayed onset of severe immune thrombocytopenia associated with COVID-19 pneumonia.

A 72-year-old Japanese man was admitted to our hospital for treatment of severe COVID-19 pneumonia and was started on favipiravir, heparin calcium, and methylprednisolone pulse therapy. He recovered from respiratory failure about one month later. However, he soon developed purpura in his lower limbs and thrombocytopenia, and immune thrombocytopenia was subsequently diagnosed.

Prognostic value of radiological findings indeterminate for UIP pattern and anterior upper lobe honeycomb-like lesion in chronic fibrosing interstitial lung disease associated with MPO-ANCA.

Background: Myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) is often positive in patients with interstitial lung disease (ILD), which is also often present in patients with microscopic polyangiitis (MPA). A possible association between MPO-ANCA, MPA, and idiopathic ILD remains unclear. The objective of this study was to determine whether high-resolution computed tomography (HRCT) classification based on recent idiopathic pulmonary fibrosis guideline and specific CT findings can obtain new knowledge of prognostic factors in all MPO-ANCA-positive patients with ILD including both idiopathic ILD and MPA-ILD.

A patient with hepatocellular carcinoma who developed invasive pulmonary aspergillosis after corticosteroid treatment.

Lung or head and neck cancer have been indicated as solid cancers associated with invasive pulmonary aspergillosis (IPA), but the relationship with hepatocellular carcinoma (HCC) is unknown. We report a case of HCC in which the presence of cirrhosis and corticosteroid administration may have caused the development of IPA.

Ultrasonographic study of umbilical cord twist direction during second trimester.

Objective: To explore/study/evaluate the relationships among umbilical twist direction, the degree of umbilical twist and differences of umbilical arterial diameters (UAD).

Methods: All obstetric patients presenting for prenatal care of singleton fetuses between 18 and 25 weeks gestation to a single provider (MN) from 2015 to 2018 had detailed umbilical cord Doppler measurements. Data including the cord twist direction, degree of twist and number of twists per cord segment length, and the diameters of each UA (UAD) and the umbilical vein (UVD) were extracted from the records.

The routine use of prophylactic Bakri balloon tamponade contributes to blood loss control in major placenta previa.

Objective: To verify the blood loss control effect of routine prophylactic Bakri balloon tamponade on major and minor placenta previa (PP).

Methods: We conducted a retrospective cohort study of all singleton pregnancies that involved cesarean section (CS) for PP at our hospital. All participants were divided into Bakri balloon (underwent routine prophylactic use just after placenta removal) and non-balloon groups, and into major and minor PP groups.

The Usefulness of a Transbronchial Lung Cryobiopsy for Diffuse Bronchiolitis.

We herein report four cases of diffuse bronchiolitis proven by a transbronchial lung cryobiopsy (TBLC). Based on various aspects, including the pathological findings, we definitively diagnosed two patients with diffuse panbronchiolitis (DPB) and the other two with primary ciliary dyskinesia (PCD). One of the DPB patients had more severe peribronchiolar fibrosis than the other, and the disease course was refractory to macrolide therapy.

Levetiracetam-induced interstitial lung disease in a patient with advanced lung cancer.

An 85-year-old woman with antibiotics-resistant pneumonia after surgery for metastatic brain tumor from lung cancer was consulted to our department. Chest CT showed diffuse GGO bilaterally. BALF showed elevated ratios of lymphocytes and CD4/CD8.

The potential utility of anterior upper lobe honeycomb-like lesion in interstitial lung disease associated with connective tissue disease.

Background: Interstitial lung disease (ILD) is associated with high morbidity and mortality in patients with connective tissue disease (CTD). Because some patients with CTD overlap present with ILD first, with CTD diagnosed later, specific radiologic signs are needed to help differentiate each CTD or CTD-ILD from idiopathic ILD.

Objectives: To determine whether specific CT findings can help differentiate CTD as rheumatoid arthritis (RA), systemic sclerosis (SSc), or polymyositis/dermatomyositis (PM/DM).

Perinatal outcomes of cases with umbilical hypocoiled cord: a study at a single perinatal center.

Objectives: To evaluate the perinatal outcomes of hypocoiled cord.

Methods: This retrospective study was carried out in the Department of Obstetrics and Gynecology at Showa University Hospital between 2011 and 2017. Umbilical cord index (UCI) was calculated by dividing the total number of coils by the total length of umbilical cord.
