A Double-Blind, Randomized, Placebo-Controlled, Phase II Clinical Study To Evaluate the Efficacy and Safety of Camostat Mesylate (DWJ1248) in Adult Patients with Mild to Moderate COVID-19.

Although several antiviral agents have become available for coronavirus disease 2019 (COVID-19) treatment, oral drugs are still limited. Camostat mesylate, an orally bioavailable serine protease inhibitor, has been used to treat chronic pancreatitis in South Korea, and it has an in vitro inhibitory potential against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study was a double-blind, randomized, placebo-controlled, multicenter, phase 2 clinical trial in mild to moderate COVID-19 patients. We randomly assigned patients to receive either camostat mesylate (DWJ1248) or placebo orally for 14 days. The primary endpoint was time to clinical improvement of subject symptoms within 14 days, measured using a subjective 4-point Likert scale. Three hundred forty-two patients were randomized. The primary endpoint was nonsignificant, where the median times to clinical improvement were 7 and 8 days in the camostat mesylate group and the placebo group, respectively (hazard ratio [HR] = 1.09; 95% confidence interval [CI], 0.84 to 1.43; P = 0.50). A post hoc analysis showed that the difference was greatest at day 7, without reaching significance. In the high-risk group, the proportions of patients with clinical improvement up to 7 days were 45.8% (50/109) in the camostat group and 38.4% (40/104) in the placebo group (odds ratio [OR] = 1.33; 95% CI, 0.77 to 2.31; P = 0.31); the ordinal scale score at day 7 improved in 20.0% (18/90) of the camostat group and 13.3% (12/90) of the placebo group (OR = 1.68; 95% CI, 0.75 to 3.78; P = 0.21). Adverse events were similar in the two groups. Camostat mesylate was safe in the treatment of COVID-19. Although this study did not show clinical benefit in patients with mild to moderate COVID-19, further clinical studies for high-risk patients are needed. (This trial was registered with ClinicalTrials.gov under registration no. NCT04521296).

Identification of a potentially avoidable cardiopulmonary resuscitation in hematology and oncology wards.

BACKGROUND: In-hospital cardiopulmonary resuscitation (CPR) is one of undesirable situations. We tried to identify and characterize a potentially avoidable CPR in cancer patients who were hospitalized in hematology and oncology wards. METHODS: A potentially avoidable CPR was determined based on chemotherapy setting, disease status and clinical situation at the time when a cardiopulmonary arrest occurred, by using a consensus-driven medical records review of two physicians. RESULTS: One hundred thirty-seven patients among 12,437 patients hospitalized at hematology and oncology wards between March 2003 and June 2015 (1.1%) underwent a CPR. Eighty-eight patients (64.2%) were men. The majority of patients with a CPR had lung cancer (41, 29.9%), hematologic malignancy (24, 17.5%), stomach cancer (23, 16.8%) or lymphoma (20, 14.6%). A potentially avoidable CPR was identified in 51 patients (37.2%). In a multivariate analysis, advanced diseases and certain tumor types (e.g., lung cancer, lymphoma) were significant risk factors for a potentially avoidable CPR. Of patients who received a potentially avoidable CPR, 29 patients (56.9%) did not have a do-not-resuscitate documentation. A first return of spontaneous circulation rate (ROSC) and in-hospital survival rate (IHSR) were much lower in patients with a potentially avoidable CPR than those with a CPR that was not avoidable (ROSC: 39.2% vs 53.5%, P = 0.106; IHSR: 2.0% vs 12.8%, P = 0.032, respectively). CONCLUSIONS: A potentially avoidable CPR was common at hematology and oncology wards. A potentially avoidable CPR frequently occurred in advanced diseases and certain tumor types. Furthermore, cancer patients who received a potentially avoidable CPR showed the worse prognosis.

Correction to: Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

While recently extending that research, however, we discovered that 236 members of the general population were mistakenly duplicated by the investigating agency (Word Research) and 1241 were reported rather than 1005. Here, we present corrections and discuss the relevant data.

Comparison of attitudes towards five end-of-life care interventions (active pain control, withdrawal of futile life-sustaining treatment, passive euthanasia, active euthanasia and physician-assisted suicide): a multicentred cross-sectional survey of Korean patients with cancer, their family caregivers, physicians and the general Korean population.

OBJECTIVES: This study determined attitudes of four groups-Korean patients with cancer, their family caregivers, physicians and the general Korean population-towards five critical end-of-life (EOL) interventions-active pain control, withdrawal of futile life-sustaining treatment (LST), passive euthanasia, active euthanasia and physician-assisted suicide. DESIGN AND SETTING: We enrolled 1001 patients with cancer and 1006 caregivers from 12 large hospitals in Korea, 1241 members of the general population and 928 physicians from each of the 12 hospitals and the Korean Medical Association. We analysed the associations of demographic factors, attitudes towards death and the important components of a 'good death' with critical interventions at EoL care. RESULTS: All participant groups strongly favoured active pain control and withdrawal of futile LST but differed in attitudes towards the other four EoL interventions. Physicians (98.9%) favoured passive euthanasia more than the other three groups. Lower proportions of the four groups favoured active euthanasia or PAS. Multiple logistic regression showed that education (adjusted OR (aOR) 1.77, 95% CI 1.33 to 2.36), caregiver role (aOR 1.67, 95% CI 1.34 to 2.08) and considering death as the ending of life (aOR 1.66, 95% CI 1.05 to 1.61) were associated with preference for active pain control. Attitudes towards death, including belief in being remembered (aOR 2.03, 95% CI 1.48 to 2.79) and feeling 'life was meaningful' (aOR 2.56, 95% CI 1.58 to 4.15) were both strong correlates of withdrawal of LST with the level of monthly income (aOR 2.56, 95% CI 1.58 to 4.15). Believing 'freedom from pain' negatively predicted preference for passive euthanasia (aOR 0.69, 95% CI 0.55 to 0.85). In addition, 'not being a burden to the family' was positively related to preferences for active euthanasia (aOR 1.62, 95% CI 1.39 to 1.90) and PAS (aOR 1.61, 95% CI 1.37 to 1.89). CONCLUSION: Groups differed in their attitudes towards the five EoL interventions, and those attitudes were significantly associated with various attitudes towards death.

Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

PURPOSE: Understanding the concept of a "good death" is crucial to end-of-life care, but our current understanding of what constitutes a good death is insufficient. Here, we investigated the components of a good death that are important to the general population, cancer patients, their families, and physicians. METHODS: We conducted a stratified nationwide cross-sectional survey of cancer patients and their families from 12 hospitals, physicians from 12 hospitals and the Korean Medical Association, and the general population, investigating their attitudes toward 10 good-death components. FINDINGS: Three components-"not be a burden to the family," "presence of family," and "resolve unfinished business"-were considered the most important components by more than 2/3 of each of the three groups, and an additional three components-"freedom from pain," "feel that life was meaningful," and "at peace with God"-were considered important by all but the physicians group. Physicians considered "feel life was meaningful," "presence of family," and "not be a burden to family" as the core components of a good death, with "freedom from pain" as an additional component. "Treatment choices' followed, "finances in order," "mentally aware," and "die at home" were found to be the least important components among all four groups. CONCLUSION: While families strongly agreed that "presence of family" and "not be a burden to family" were important to a good death, the importance of other factors differed between the groups. Health care providers should attempt to discern each patient's view of a good death.

Prevalence and prognostic implications of psychological distress in patients with gastric cancer.

BACKGROUND: The aim of this study was to investigate the prevalence and prognostic significance of psychological distress in gastric cancer patients. METHODS: The study population included 229 gastric cancer patients visiting Yonsei Cancer Center between November 2009 and March 2011. The distress was measured by available tools including the Modified Distress Thermometer (MDT), Hospital Anxiety and Depression Scale (HADS), and Center for Epidemiologic Studies-Depression Scale (CES-D). Patients with psychological distress were defined as those who scored above the cut-off values in both the MDT and either one of the HADS or CES-D. RESULTS: The median age of patients was 56 (range, 20 to 86) and 97 (42.4%) patients were with stage IV disease status at enrollment. The overall prevalence of psychological distress was 33.6% (95% CI: 27.5-39.8%) in 229 gastric cancer patients. In multiple logistic regression analysis, lower education level (odds ratio [OR] 2.39; 95% confidence interval [CI] 1.11-5.17, P = 0.026) and higher disease stage (OR 2.72; 95% CI 1.47-5.03, P = 0.001) were associated with psychological distress. In stage I-III disease, patients with psychological distress had worse disease-free survival (DFS) (5-year DFS rate: 60% vs 76%, P = 0.49) compared with those without psychological distress. In stage IV disease (n = 97), patients with psychological distress showed poorer overall survival than those without psychological distress (median OS (Overall Survival): 12.2 vs. 13.8 months, P = 0.019). CONCLUSION: Psychological distress is common in patients with all stages of gastric cancer and is associated with worse outcomes.

A case of occupational hypersensitivity pneumonitis associated with trichloroethylene.

Trichloroethylene (TCE) is a toxic chemical commonly used as a degreasing agent, and it is usually found in a colorless or blue liquid form. TCE has a sweet, chloroform-like odor, and this volatile chlorinated organic chemical can cause toxic hepatitis, neurophysiological disorders, skin disorders, and hypersensitivity syndromes. However, the hypersensitivity pneumonitis (HP) attributed to TCE has rarely been reported. We hereby describe a case of HP associated with TCE in a 29-year-old man who was employed as a lead welder at a computer repair center. He was installing the capacitors on computer chip boards and had been wiped down with TCE. He was admitted to our hospital with complaints of dry coughs, night sweats, and weight losses for the past two months. HP due to TCE exposure was being suspected due to his occupational history, and the results of a video-associated thoracoscopic biopsy confirmed the suspicions. Symptoms have resolved after the steroid pulse therapy and his occupational change. TCE should be taken into consideration as a potential trigger of HP. Early recognition and avoidance of the TCE exposure in the future is important for the treatment of TCE induced HP.

Ifosfamide-induced Fanconi syndrome with diabetes insipidus.

Ifosfamide-induced Fanconi syndrome is a rare complication that typically occurs in young patients due to a cumulative dose of ifosfamide > 40-60 g/m(2), a reduction in kidney mass, or concurrent cisplatin treatment. It is usually characterized by severe and fatal progression accompanied by type II proximal renal tubular dysfunction, as evidenced by glycosuria, proteinuria, electrolyte loss, and metabolic acidosis. Diabetes insipidus is also a rare complication of ifosfamide-induced renal disease. We herein describe a case involving a 61-year-old man who developed ifosfamide-induced Fanconi syndrome accompanied by diabetes insipidus only a few days after the first round of chemotherapy. He had no known risk factors. In addition, we briefly review the mechanisms and possible therapeutic options for this condition based on other cases in the literature. Patients who receive ifosfamide must be closely monitored for renal impairment to avoid this rare but fatal complication.

[A case of IgG4 associated sclerosing cholangitis without clinical manifestations of autoimmune pancreatitis].

IgG4-related systemic diseases are characterized by a diffuse or mass forming inflammatory reaction rich in lymphocytes and IgG4-positive plasma cells (lymphoplasmacytic infiltration), fibrosclerosis of variable organs and obliterative phlebitis. They usually involve various organs including the pancreas, bile duct, gallbladder, salivary gland, retroperitoneum, kidney, lung, and prostate. However, most of them are accompanied by autoimmune pancreatitis, and good response to steroid treatment is one of the hallmarks of this disease. We report a case of an 67-year-old man with IgG4 associated sclerosing cholangitis, who was diagnosed by endoscopic retrograde cholangiopancreatography and successfully treated with steroid therapy.

[A case of successful treatment of portal venous gas caused by acute pancreatitis].

Hepatic portal venous gas (HPVG) has been considered a rare entity associated with a poor prognosis. Portal vein gas is most commonly caused by mesenteric ischemia but may have a variety other causes. HPVG can be associated with ischemic bowel disease, inflammatory bowel disease, intra-abdominal abscess, small bowel obstruction, acute pancreatitis, and gastric ulcer. Because of high mortality rate, most HPVG requires emergent surgical interventions and intensive medical management. We experienced a case of hepatic portal venous gas caused by acute pancreatitis and successfully treated with medical management.
