COVID‐19 case of ventilator‐induced lung injury on extracorporeal membrane oxygenation: Physicians' clinical struggle and ethical conflict in a novel pandemic

Resource scarcity was concerned in the initial surge of the COVID‐19 pandemic. To open slots for Extracorporeal Membrane Oxygenation (ECMO), we tried ECMO weaning allowing invasive ventilation in a 66‐year‐old male with severe COVID‐19, backfiring as ventilator‐induced lung injury. We will discuss ethical conflict in pandemics in this report.     

Successful predilation of a resistant,heavily calcified lesion with cutting balloon for coronary stenting: A case report

A 65-year-old man with a restenotic lesion of the mid LAD was scheduled for Wiktor stent placement. The IVUS revealed circumferential severe calcification. Two conventional, non-compliant angioplasty balloons inflated to high pressures failed to achieved sufficient dilatation and both ruptured. At this point, we selected high pressure inflation of the Cutting Balloon. The Cutting Balloon achieved adequate dilation for stenting and proved to be useful in predilating a circumferential, heavily calcified lesion. Cathet. Cardiovasc.

Hepatitis B Surface Antigen Decline during Sofosbuvir and Ribavirin Therapy in Hepatitis B Inactive Carriers Who Were Co-infected with Hepatitis C

Direct-acting antiviral (DAA) therapy carries a potential risk of inducing hepatitis B virus (HBV) reactivation. However, the HBV kinetics during and after DAA therapy in patients co-infected with hepatitis C virus (HCV) and HBV remain unknown. We retrospectively evaluated the HBV kinetics during and after sofosbuvir/ribavirin therapy in four HBV inactive carriers co-infected with HCV. HCV was eradicated in all patients. Changes in HBV-DNA levels during treatment differed among patients. The hepatitis B surface antigen (HBsAg) levels uniformly decreased (mean -0.530 logIU/mL) by the end of treatment and returned to near the baseline in all patients. Sofosbuvir/ribavirin therapy thus demonstrated a suppressive effect on HBsAg.     

Prognosis of patients with adult T‐cell leukemia/lymphoma in Japan: A nationwide hospital‐based study

Adult T‐cell leukemia/lymphoma (ATL) is a mature T‐cell neoplasm and is classified into four subtypes (acute, lymphoma, chronic, and smoldering) according to the Shimoyama classification, established in 1991 through several nationwide surveys based on the clinical diversity of patients diagnosed in 1983‐1987 in Japan. Thereafter, no such studies have been conducted. Recently, we conducted a nationwide hospital survey using the method of the 1980s studies, collected baseline data on 996 ATL patients diagnosed in 2010‐2011 from 126 hospitals, and reported their unique epidemiological characteristics. Here, we report the follow‐up results of registered ATL patients with the goal of evaluating current prognoses and treatment modalities as of 2016‐2017. Of 770 evaluable patients, 391 (50.8%) had acute‐type, 192 (24.9%) had lymphoma‐type, 106 (13.8%) had chronic‐type, and 81 (10.5%) had smoldering‐type ATL. The initial therapy regimens used for acute/lymphoma‐type ATL were vincristine, cyclophosphamide, doxorubicin and prednisone, followed by doxorubicin, ranimustine, and prednisone and then by vindesine, etoposide, carboplatin, and prednisone (VCAP‐AMP‐VECP)‐like in 38.5/41.7% and cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)‐like in 14.6/13.7% of patients. Allogeneic hematopoietic stem cell transplantation was used to treat 15.9/10.4% of acute/lymphoma‐type ATL patients. The 4‐year survival rates (the median survival time, days) for acute‐, lymphoma‐, unfavorable chronic‐, favorable chronic‐, and smoldering‐type ATL were 16.8% (252), 19.6% (305), 26.6% (572), 62.1% (1937), and 59.8% (1851), respectively. The 4‐year survival rates for acute‐ and lymphoma‐type ATL improved compared with those reported in 1991, but those for chronic‐ and smoldering‐type ATL were not. Further efforts are warranted to develop more efficient therapeutic strategies to improve the prognosis of ATL in Japan.     

Effects of bezafibrate on HDL2/HDL3 ratio in postmenopausal hypertriglyceridemic women

The short-term effects of bezafibrate on high-density lipoprotein cholesterol quality and triglyceride-rich lipoprotein metabolism in 186 postmenopausal hypertriglyceridemic women were investigated. Patients were randomized to an untreated group and to bezafibrate (400 mg/d) for 6 months. Fasting lipid concentrations, high-density lipoprotein 2, and high-density lipoprotein 3 levels were measured at baseline and after 3 and 6 months. At 3 months, bezafibrate had significantly decreased mean serum triglycerides and remnant-like particle cholesterol levels (105.7 +/- 43.4 mg/dL and 5.33 +/- 2.1 mg/dL, P < .001, respectively) from baseline values (232.5 +/- 63.9 mg/dL and 9.69 +/- 3.8 mg/dL, respectively). It also maintained lower total cholesterol, low-density lipoprotein cholesterol, triglycerides, and remnant-like particle cholesterol concentrations to 6 months. After 3 months, it significantly increased mean serum high-density lipoprotein cholesterol (55.1 +/- 14.7 vs 64.8 +/- 12.1 mg/dL; P < .0001) and maintained higher high-density lipoprotein cholesterol at 6 months. The high-density lipoprotein 2-high-density lipoprotein 3 ratio was decreased after 3 months of therapy with bezafibrate (2.13 +/- 0.68) from the baseline (2.42 +/- 0.71) (P < .01).
