PURPOSE: The purpose of this study is to suggest a treatment strategy for stage IV gastric cancer by investigating the behavioral difference between initially and recurrent metastatic disease. METHODS: We reviewed the medical records of the patients who underwent chemotherapy alone for metastatic gastric cancer between January 2006 and September 2013. Patients were divided into those who underwent chemotherapy for metastatic disease since initial diagnosis (IM group) and for metastatic recurrence after curative surgery (RM group). Survival and causes of death were compared between the 2 groups, and significant prognostic factors were also investigated. RESULTS: A total of 170 patients were enrolled in this study. Of these patients, 104 were included in the IM group and 66 in the RM group. Overall survival of the IM group did not differ from that of RM (P = 0.569). In the comparison of the causes of death, the IM group had a greater tendency to die from bleeding (P = 0.054) and pneumonia (P = 0.055). In multivariate analysis, bone metastasis (P < 0.001; HR = 2.847), carcinoma peritonei (P = 0.047; HR = 1.766), and the frequency of chemotherapy (P < 0.001; HR = 0.777) were significantly associated with overall survival of IM group. CONCLUSION: Disease-burden mainly contributes to the prognosis of metastatic gastric cancer, although noncurative gastrectomy may be helpful in reducing the mortality of initially metastatic disease. Therefore, disease-burden should be also prioritized in determining the treatment strategies for stage IV gastric cancer.

OBJECTIVES:
To develop a new Chinese medicine (CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome (ARDS) in COVID-19 patients.
METHODS:
A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized, controlled two-arm trial. The two arms of the trial consist of a control therapy (alpha interferon inhalation, 50 µg twice daily; and lopinavir/ritonavir, 400 and 100 mg twice daily, respectively) and a testing therapy (control therapy plus Keguan-1 19.4 g twice daily) by random number table at 1:1 ratio with 24 cases each group. After 2-week treatment, adverse events, time to fever resolution, ARDS development, and lung injury on newly diagnosed COVID-19 patients were assessed.
RESULTS:
An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events. Based on this result, the study was expanded to include a total of 48 participants (24 cases each arm). The results show that compared with the control arm, the testing arm exhibited a significant improvement in time to fever resolution (P=0.035), and a significant reduction in the development of ARDS (P=0.048).
CONCLUSIONS
Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients. (Trial registration No. NCT04251871 at www.clinicaltrials.gov ).

BACKGROUND/AIMS: Whether the causative organism influences the clinical course of pneumonia in the intensive care unit (ICU) is controversial. We assessed the clinical manifestations and prognosis of pneumonia according to the causative pathogens in patients in a medical ICU. METHODS: A retrospective observational study was performed in a medical ICU. Among 242 patients who were admitted to the ICU, 103 who were treated for pneumonia were analyzed. RESULTS: The causative pathogen was identified in 50 patients (49.0%); 22 patients (21.6%) had multidrug-resistant (MDR) pathogens. The distribution of causative micro-organisms was Staphylococcus aureus (20%), Pseudomonas species (16%), Klebsiella pneumoniae (14%), and Acinetobacter baumannii (12%). No significant difference in ICU mortality rate, duration of ICU stay, duration of mechanical ventilation, or frequencies of re-intubation and tracheostomy were detected based on the identification of any pathogen. In sub-analyses according to the pneumonia classification, the number of pathogens identified did not differ between pneumonia types, and a higher incidence of identified MDR pathogens was detected in the hospital-acquired pneumonia group than in the community-acquired or healthcare- acquired pneumonia groups. However, the clinical outcomes of pneumonia according to identification status and type of pathogen did not differ significantly between the groups. CONCLUSIONS: Neither the causative micro-organism nor the existence of MDR pathogens in critically ill patients with pneumonia was associated with the clinical outcome of pneumonia, including ICU mortality. This result was consistent regardless of the pneumonia classification.

The purpose of this study was to investigate the clinical aspects of patients satisfying the Infectious Disease Society of America/American Thoracic Society (IDSA/ATS) minor severity criteria, focusing on their treatment response to empirical antibiotics. In total, 381 community-acquired pneumonia (CAP) patients who did not require mechanical ventilation or vasopressors at admission were enrolled, and 50 (13.1%) satisfied the minor severity criteria (i.e. , minor severe CAP [minor-SCAP]). The rates of new complication events and clinical treatment failure were significantly higher in the minor-SCAP group than in the control group (30.0% vs 2.1%, P < 0.001, and 42.0% vs 10.6%, P < 0.001, respectively), and the time to reach clinical stability was longer in the minor-SCAP group (8 days vs 3 days, P < 0.001). In a multivariate model, minor severity criteria (> or = 3) were significantly associated with treatment failure (odds ratio, 2.838; 95% confidence interval, 1.216 to 6.626), and for predicting treatment failure the value of the area under the receiver operating characteristic curve for minor criteria was 0.731, similar to other established scoring methods. The IDSA/ATS minor severity criteria can predict delayed treatment response and clinical treatment failure.

BACKGROUND/AIMS: Recently, the incidence of nursing home-acquired pneumonia (NHAP) has been increasing and is now the leading cause of death among nursing home residents. This study was performed to identify risk factors associated with NHAP mortality, focusing on facility characteristics. METHODS: Data on all patients > or = 70 years of age admitted with newly diagnosed pneumonia were reviewed. To compare the quality of care in nursing facilities, the following three groups were defined: patients who acquired pneumonia in the community, care homes, and care hospitals. In these patients, 90-day mortality was compared. RESULTS: Survival analyses were performed in 282 patients with pneumonia. In the analyses, 90-day mortality was higher in patients in care homes (12.2%, 40.3%, and 19.6% in community, care homes, and care hospitals, respectively). Among the 118 NHAP patients, residence in a care home, structural lung diseases, treatment with inappropriate antimicrobial agents for accompanying infections, and a high pneumonia severity index score were risk factors associated with higher 90-day mortality. However, infection by potentially drug-resistant pathogens was not important. CONCLUSIONS: Unfavorable institutional factors in care homes are important prognostic factors for NHAP.

6.Clinical characteristics of nursing home-acquired pneumonia in elderly patients admitted to a Korean teaching hospital.
The Korean Journal of Internal Medicine 2015;30(5):638-647
BACKGROUND/AIMS: Nursing home-acquired pneumonia (NHAP) is included under healthcare-associated pneumonia. However, the optimal treatment strategy for NHAP has been controversial in several studies. We evaluated the clinical features of NHAP compared to community-acquired pneumonia (CAP) in elderly patients admitted with pneumonia. METHODS: This was a retrospective study in elderly patients aged > or = 65 years with NHAP or CAP who were hospitalized at Jeju National University Hospital between January 2012 and April 2013. RESULTS: A total of 209 patients were enrolled, and 58 (27.7%) had NHAP. The patients with NHAP were older, had more frequent central nervous system disorders, and showed worse clinical parameters. Potential drug-resistant pathogens were more frequently detected in the NHAP group (22.4% vs. 9.9%, p = 0.018), and the incidences of Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were 8.6% and 10.3%, respectively. In-hospital mortality occurred in 13 patients (22.4%) with NHAP and 17 patients (11.2%) with CAP (p = 0.039). In multivariate analyses, only higher pneumonia severity index (PSI) score was associated with increased mortality (p < 0.001), and the PSI score was higher in the NHAP group than that in the CAP group. CONCLUSIONS: Elderly patients admitted with NHAP showed more severe pneumonia at onset, higher rates of potentially drug-resistant pathogens, and worse clinical outcomes than those with CAP. However, higher in-hospital mortality in those with NHAP seemed to be related to the PSI score reflecting host factors and severity of pneumonia rather than the type of pneumonia or the presence of drug-resistant pathogens.

To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis.
Results: The clinical manifestations of pulmonary histoplasmosis were mild, such as dry cough. However, the main clinical symptoms of progressive disseminated histoplasmosis were severe, including recurrence of high fever, superficial lymph node enlargement over the whole body, hepatosplenomegaly, accompanied by cough, abdominal pain, joint pain, skin changes, etc.Laboratory examination showed pancytopenia, abnormal liver function and abnormal coagulation function. One pulmonary case received the operation of left lower lung lobectomy, 3 cases of pulmonary histoplasmosis and 6 cases of progressive disseminated histoplasmosis patients were given deoxycholate amphotericin B, itraconazole, voriconazole or fluconazole for antifungal therapy. One disseminated case discharged from the hospital without treatment after diagnosis of histoplasmosis, and 1 disseminated case combined with severe pneumonia and active tuberculosis died ultimately.
Conclusion: As a rare fungal infection, histoplasmosis is easily to be misdiagnosed. The diagnostic criteria depends on etiology through bone marrow smear and tissues biopsy. Liposomeal amphotericin B, deoxycholate amphotericin B and itraconazole are recommended to treat infection for histoplasma capsulatum.
