Undernutrition and cachexia have been suggested to be risk factors for postoperative complications and survival in cancer patients. The aim of this study was to investigate whether body mass index (BMI) is related to the short-term and long-term outcomes in patients who undergo an esophagectomy for the resection of esophageal squamous cell cancer (ESCC). Three hundred forty patients who underwent an esophagectomy for the resection of ESCC between 2003 and 2008 were retrospectively reviewed. The patients were divided into two groups: an L-BMI group characterized by a BMI < 18.5 kg/m(2) and an N-BMI group characterized by a BMI ≥ 18.5 kg/m(2). Clinical and pathological outcome were compared between groups. The study included 40 patients in the L-BMI group and 300 patients in the N-BMI group. A clinicopathological assessment showed that nodal involvement was seen more frequently in the L-BMI group (P = 0.016). Pulmonary complications seemed to occur more frequently in the L-BMI group (P = 0.006). The 5-year overall survival rate was higher in the N-BMI group (63.6%) than in the L-BMI group (32.3%) (P < 0.001). The 5-year disease-free survival rate was also higher in the N-BMI group (58.0%) than in the L-BMI group (33.6%) (P = 0.001). In multivariate analysis, the BMI (hazard ratio, 2.154; 95% CI, 1.349-3.440, P = 0.001) was found to be an independent prognostic factor for overall survival. Our data suggested that a lower BMI not only increased pulmonary complications but also impaired overall and disease-free survival after an esophagectomy for the resection of ESCC.
Case 1: A 65-year-old man with novel coronavirus infection (COVID-19) complicated with acute respiratory failure. On admission, the patient was started on favipiravir and corticosteroid. However, due to a lack of significant improvement, he was introduced to mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Although iliopsoas hematoma occurred as a complication, the patient recovered. Case 2: A 49-year-old man with COVID-19 had been started on favipiravir and corticosteroid. Due to progressive respiratory failure, the patient underwent mechanical ventilation and ECMO. The patient recovered without complications. We successfully treated these severe cases with a multimodal combination of pharmacological and non-pharmacological supportive therapy.
Objective
We aimed to clarify clinical and laboratory characteristics of coronavirus disease 2019 (COVID-19) patients, and further explore the features to detect COVID-19 pneumonia at the first visit to community-based hospitals.
Methods
Diagnoses of COVID-19 were based on positive results from real-time reverse-transcription polymerase chain reaction testing of nasopharyngeal-swab specimens. We retrospectively reviewed the medical records of patients showing positive results. The clinical characteristics and results of blood tests were compared between the patients with and without pneumonia. The risk factors associated with pneumonia were then evaluated by a multivariable analysis.
Results
The study cohort comprised 154 patients, including 117 patients (76.0%) with pneumonia at first visit. Significant differences were seen in age, the frequency of fever, tachycardia, desaturation (peripheral oxygen saturation ≤95%), any comorbidity, neutrocyte count and fraction, lymphocyte count and fraction, platelet count, lactate dehydrogenase (LDH), C-reactive protein (CRP), and fibrinogen between the patients with and without pneumonia. Using a multivariable analysis, CRP ≥0.3 mg/dL and fibrinogen >400 mg/dL were found to be associated with the presence of pneumonia.
Conclusion
Community-based settings for screening COVID-19 patients should perform chest X-ray and blood tests for white blood cell fractions, fibrinogen, LDH, and CRP. Of these, elevations in the CRP and fibrinogen levels could be critically associated with the presence of COVID-19 pneumonia.
We report two cases that were diagnosed with either acute exacerbation of chronic heart failure or acute decompensated heart failure due to acute myocardial infarction; both cases exhibited computed tomography (CT) findings of the periportal collar sign in the liver and lymphedema in the hepatoduodenal ligament and retroperitoneal space. Both of these signs, particularly lymphedema in the hepatoduodenal ligament and anterior pararenal space, are considered very important CT findings when diagnosing acute decompensated heart failure.
A 49-year-old Japanese male was managed by mechanical ventilation due to coronavirus disease 2019 (COVID-19) pneumonia. Favipiravir as an antiviral therapy, and anti-inflammatory treatment were administered. SARS-CoV-2 RNA was detected in serum by the loop-mediated isothermal amplification (LAMP) method on Day 9; favipiravir treatment was continued. On Day 13, negative serum RNA was confirmed, followed by mechanical ventilation was removed. On Day 23, LAMP negative was confirmed in nasopharynx, after that the patient discharged on Day 27. We could treat successfully for severe COVID-19 pneumonia based on the LAMP method. We consider this method will be useful in COVID-19 treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
