The Unfolded Protein Response Is Associated with Cancer Proliferation and Worse Survival in Hepatocellular Carcinoma.

Hepatocellular carcinoma is a leading cause of cancer death worldwide. The unfolded protein response (UPR) has been revealed to confer tumorigenic capacity in cancer cells. We hypothesized that a quantifiable score representative of the UPR could be used as a biomarker for cancer progression in HCC.

Subgroup analysis of the AFTER I-O study: a retrospective study on the efficacy and safety of subsequent molecular targeted therapy after immune-oncology therapy in Japanese patients with metastatic renal cell carcinoma.

Background: We performed subgroup analyses of the AFTER I-O study to clarify the association of time-to-treatment failure (TTF) and discontinuation reason of prior immune-oncology (I-O) therapy, and molecular targeted therapy (TT) regimen with the outcomes of TT after I-O.

Methods: The data of Japanese metastatic renal cell carcinoma patients treated with TT after nivolumab (NIVO) (CheckMate 025) or NIVO + ipilimumab (IPI) (CheckMate 214) were retrospectively analyzed. The objective response rates (ORRs), progression-free survival (PFS) and overall survival (OS) of TT after I-O were analyzed by subgroups: TTF (<6 or ≥6 months) and discontinuation reason of prior I-O (progression or adverse events), and TT regimen (sunitinib or axitinib).

Effectiveness of EUS-Guided Fine-Needle Biopsy versus EUS-Guided Fine-Needle Aspiration: A Retrospective Analysis.

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic tumors and subepithelial lesions (SEL) of the gastrointestinal tract are effective for histological diagnosis. There are also reports that tissue sampling is possible with a smaller number of punctures by EUS-guided fine-needle biopsy (EUS-FNB). In this study, we retrospectively compared the diagnostic abilities of EUS-FNA and EUS-FNB.

Macular holes following vitrectomy for rhegmatogenous retinal detachment: epiretinal proliferation and spontaneous closure of macular holes.

Purpose: To describe the characteristics and management of full-thickness macular holes (MHs) that develop after pars plana vitrectomy for rhegmatogenous retinal detachment (RD).

Methods: Retrospective, interventional, consecutive case series. Patients who developed secondary full-thickness MHs after prior pars plana vitrectomy for RD over a 6-year period were included.

Aerobic Exercise Ameliorates Cancer Cachexia-Induced Muscle Wasting through Adiponectin Signaling.

Cachexia is a multifactorial syndrome characterized by muscle loss that cannot be reversed by conventional nutritional support. To uncover the molecular basis underlying the onset of cancer cachectic muscle wasting and establish an effective intervention against muscle loss, we used a cancer cachectic mouse model and examined the effects of aerobic exercise. Aerobic exercise successfully suppressed muscle atrophy and activated adiponectin signaling.

Randomized trial of granulocyte colony-stimulating factor for spinal cord injury.

Attenuation of the secondary injury of spinal cord injury (SCI) can suppress the spread of spinal cord tissue damage, possibly resulting in spinal cord sparing that can improve functional prognoses. Granulocyte colony-stimulating factor (G-CSF) is a haematological cytokine commonly used to treat neutropenia. Previous reports have shown that G-CSF promotes functional recovery in rodent models of SCI.

The SUN2-nesprin-2 LINC complex and KIF20A function in the Golgi dispersal.

The morphology of the Golgi complex is influenced by the cellular context, which strictly correlates with nuclear functions; however, the mechanism underlying this association remains elusive. The inner nuclear membrane SUN proteins, SUN1 and SUN2, have diverse functions together with the outer nuclear membrane nesprin proteins, which comprise the LINC complex. We found that depletion of SUN1 leads to Golgi complex dispersion with maintenance of ministacks and retained function for vesicle transport through the Golgi complex.

Investigating the clinical usefulness of definitions of progression with 10-2 visual field.

Background/aim: To investigate the clinical validity of the Guided Progression Analysis definition (GPAD) and cluster-based definition (CBD) with the Humphrey Field Analyzer 10-2 test in diagnosing glaucomatous visual field (VF) progression, and to introduce a novel definition with optimised specificity by combining the 'any-location' and 'cluster-based' approaches (hybrid definition).

Methods: 64 400 stable glaucomatous VFs were simulated from 664 pairs of 10-2 tests (10 sets × 10 VF series × 664 eyes; data set 1). Using these simulated VFs, the specificity to detect progression and the effects of changing the parameters (number of test locations or consecutive VF tests, and percentile cut-off values) were investigated.

Clinical outcome of patients with recurrent or refractory localized Ewing's sarcoma family of tumors: A retrospective report from the Japan Ewing Sarcoma Study Group.

Background: Patients with Ewing's sarcoma family of tumors (ESFT) who experience relapse or progression have a poor prognosis.

Aim: This study aimed to identify the prognostic and therapeutic factors affecting overall survival (OS) of patients with recurrent or refractory localized ESFT.

Methods And Results: Thirty-eight patients with localized ESFT who experienced first relapse or progression between 2000 and 2018 were retrospectively reviewed.

Validating the usefulness of sectorwise regression of visual field in the central 10°.

Aim: To evaluate the usefulness of the application of the clustering method to the trend analysis (sectorwise regression) in comparison with the pointwise linear regression (PLR).

Methods: This study included 153 eyes of 101 patients with open-angle glaucoma. With PLR, the total deviation (TD) values of the 10th visual field (VF) were predicted using the shorter VF sequences (from first 3 to 9) by extrapolating TD values against time in a pointwise manner.

Central pontine myelinolysis during treatment of hyperglycemic hyperosmolar syndrome: a case report.

Background: Central pontine myelinolysis (CPM) is a non-inflammatory demyelinating lesion of the pons. CPM and extrapontine demyelination (EPM) are together termed osmotic demyelination syndrome (ODS), a known and serious complication of acute correction of hyponatremia. Conversely, hyperglycemic hyperosmolarity syndrome (HHS) develops in patients with type 2 diabetes who still have some insulin secretory ability due to infection, non-compliance with treatment, drugs, and coexisting diseases, and is often accompanied by ketosis.

Endoscopic placement of covered versus uncovered self-expandable metal stents for palliation of malignant gastric outlet obstruction.

Objective: Stenting is an established endoscopic therapy for malignant gastric outlet obstruction (mGOO). The choice of stent (covered vs uncovered) has been examined in prior randomised studies without clear results.

Design: In a multicentre randomised prospective study, we compared covered (CSEMS) with uncovered self-expandable metal stents (UCSEMS) in patients with mGOO; main outcomes were stent dysfunction and patient survival, with subgroup analyses of patients with extrinsic and intrinsic tumours.

Disseminated Varicella-zoster Virus Infection Causing Fatal Pneumonia in an Immunocompromised Patient with Chronic Interstitial Pneumonia.

Viral pneumonia caused by varicella-zoster virus (VZV) infection is a rare but important complication, especially regarding varicella infections. Although disseminated cutaneous herpes zoster (DCHZ) is often associated with visceral diseases, there have been few reports of DCHZ-related pneumonia. We herein report a rare case of a lethal disseminated VZV infection that caused severe pneumonia in a Japanese patient who had chronic interstitial pneumonia.

Difficulty in differential diagnosis for renal cancer with microscopic papillary architecture: overlapped pathological features among papillary renal cell carcinoma (RCC), mutinous tubular and spindle cell carcinoma, and unclassified RCC. Lessons from a Japanese multicenter study.

Objectives: In our multicenter study evaluating metastatic papillary renal cell carcinoma (PRCC), 29% of tumors diagnosed as PRCC in collaborative institutes were finally diagnosed as other RCCs under central review. In those tumors, mucinous tubular and spindle cell carcinoma (MTSCC) was the leading histology, followed by unclassified RCC (ucRCC). We focused on those patients with MTSCC or ucRCC.

Comparison of fracture risk between proton pump inhibitors and histamine-2 receptor antagonists in ANCA-associated vasculitis patients: a nested case-control study.

Objective: Whether acid suppressants [proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs)] are associated with bone fractures in patients with ANCA-associated vasculitis (AAV) treated with glucocorticoids remains unclear. This study compared PPIs with H2RAs in terms of the risk of bone fractures in patients with AAV who received in-hospital induction therapy with glucocorticoids.

Methods: We retrospectively identified 149 patients with fractures among 22 821 patients newly diagnosed with AAV in 1730 hospitals using a nationwide inpatient database from July 2010 to March 2018.

Sofosbuvir plus velpatasvir treatment for hepatitis C virus in patients with decompensated cirrhosis: a Japanese real-world multicenter study.

Background: Real-world data on the efficacy and safety of sofosbuvir plus velpatasvir (SOF/VEL) treatment for patients with hepatitis C virus (HCV)-related decompensated cirrhosis are limited in Japan.

Methods: A total of 190 patients with compensated (108) or decompensated (82) cirrhosis who initiated direct-acting antiviral (DAA) treatment between February 2019 and August 2019 were enrolled. Sustained virologic response (SVR) was defined as undetectable serum HCV-RNA at 12 weeks after the end of treatment (EOT).

Tumor-to-tumor metastasis: lung cancer within a thymoma.

Tumor-to-tumor metastasis is a rare phenomenon. We present a rare case of an 83-year-old man with pulmonary squamous cell carcinoma and thymoma. Thymectomy and superior segmentectomy of the left lower lobe were successfully performed on the patient.

Impact of Metabolic Syndrome on the Mortality Rate among Participants in a Specific Health Check and Guidance Program in Japan.

Objective In Japan, the Specific Health Check and Guidance (Tokutei-Kenshin) program was started in 2008 to decrease the social burden related to metabolic syndrome (MetS). However, so far this program has not been found to have any impact on the mortality rate. Methods The subjects consisted of individuals who participated in the Tokutei-Kenshin in seven districts between 2008 and 2015.

[A case of spastic paraplegia 48 with a novel mutation in the AP5Z1 gene].

We describe an additional patient with spastic paraplegia 48 (SPG48). A 52-year-old woman with gradually increasing gait disturbance was admitted to our hospital. When she was 47 years old, acquaintances noted a shuffling gait.

Intra-day change in occurrence of out-of-hospital ventricular fibrillation in Japan: The JCS-ReSS study.

Background: Real-world evidence of out-of-hospital ventricular fibrillation (VF), especially regarding intra-day change, remains unclear. We aimed to investigate that age- and gender-dependent difference of intra-day change of VF occurrence.

Method: We enrolled 71,692 patients (males: 56,419 [78.

Neurofibromatosis type 1 associated with hypophosphatemic osteomalacia due to hypersecretion of fibroblast growth factor 23: a case report.

Background: Neurofibromatosis type 1 is characterized by multiple café au lait spots and cutaneous and plexiform neurofibromas, and is one of the most common autosomal dominant hereditary disorders caused by mutations of the neurofibromatosis type 1 tumor suppressor gene. Osteomalacia in neurofibromatosis type 1 is very rare and is characterized by later onset in adulthood. In humans, fibroblast growth factor 23, which is a causative factor of tumor-induced osteomalacia, is not only a paracrine and autocrine factor, but is also a physiological regulator of phosphate balance in normal serum.
