The tumor microenvironment, including tumor-infiltrating lymphocytes and myeloid-derived cells, is an important factor in the pathogenesis clinical behavior of malignant lymphoma. However, prognostic significance peripheral monocytes lymphoma remains unclear.We evaluated impact absolute lymphocyte count (ALC), monocyte (AMC), lymphocyte/monocyte ratio (LMR) 359 diffuse large B-cell (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, prednisone...

Background The quick sequential organ failure assessment (qSOFA) score has recently been introduced to the emergency department (ED) and wards, it predicted a higher number of deaths among patients with sepsis compared baseline risk. However, studies about application qSOFA are limited in prehospital settings. Thus, this study aimed assess performance predicting risk mortality infection. Methods This single center, retrospective cohort was conducted Japanese tertiary care teaching hospital...

This study evaluated the efficacy of central nervous system (CNS) prophylaxis using intrathecal methotrexate (IT-MTX) in patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively studied 322 who achieved first complete remission (CR) after rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. The CNS consisted four doses IT-MTX (15 mg) hydrocortisone (25 administered CR was achieved. Forty (12%) received (group A) 282 (88%) did not B)....

Background: Combination antihypertensive therapy with an angiotensin receptor blocker (ARB) and a calcium channel (CCB) or diuretics is common. This subanalysis investigated blood pressure (BP) variability in patients receiving ARB-based combination therapy. Methods: In prospective, randomized, open-label trial, hypertensive outpatients (≥65 years) who did not achieve their target BP ARB monotherapy switched to losartan 50 mg/hydrochlorothiazide 12.5 mg (ARB + D) plus amlodipine 5 C) for 12...

Treatment with a free radical scavenger could be new option for ischemic brain attack, however, little is known about the alteration of oxidative stress markers induced by edaravone, novel scavenger, in human attack.We investigated effects edaravone on patients attack. Twenty-one attack and 19 controls were enrolled this study. Blood samples obtained just before soon after first administration (30 mg) or ozagrel (40 mg). Intracellular reactive oxygen species neutrophils measured using...

Objectives Patient outcomes after out-of-hospital cardiac arrest (OHCA) varies at multilevel (geographical regions, emergency medical service agencies and receiving hospitals) in the USA. However, it remains unclear whether there is a variation patient OHCA between relevant units of healthcare system such as hospitals Japan. Therefore, we aimed to quantify Design Secondary analysis prospective multicentre registry. Setting The Japan Association for Acute Medicine Registry, registry,...

Abstract Pirarubicin tetrahydropyranyl adriamycin (THP‐ADR) is an analogue of doxorubicin. This agent exhibits activity against some doxorubicin‐resistant cell lines. We performed a phase II study biweekly THP‐COP [50 mg/m 2 pirarubicin, 750 cyclophosphamide, 1.4 vincristine (2.0 mg maximum) on day 1, and 100 mg/body predonisolone days 1–5] in patients with peripheral T‐cell lymphoma (PTCL). Seventeen newly diagnosed PTCL were enrolled. Histological diagnoses PTCL, not otherwise specified (...

Cytomegalovirus (CMV) reactivation and natural killer (NK) cell reconstitution are well-recognized immunologic events occurring after allogeneic stem transplantation (allo-SCT). We aimed to study the outcome of CMV (CMVR) NK in patients with hematologic malignancies allo-SCT. retrospectively studied 246 adult (152 men, 94 women; median age, 51 years [range, 18 69]) who underwent allo-SCT for at Kanagawa Cancer Center.
