RESUMEN
Background/Aims@#Anastomotic stricture at the esophagus and the conduit anastomosis site after the surgical resection of esophageal cancer is relatively common. This study examined whether a hypertrophic scar or keloid formation at a surgical wound is related to an anastomotic stricture. @*Methods@#From March 2007 to July 2017, 59 patients underwent curative surgery for esophageal cancer. In 38 patients, end-to-end anastomosis (EEA) of the esophagus and the conduit was performed using EEA 25 mm. A hypertrophic wound scar was defined when the width of the midline laparotomy wound scar exceeded 2 mm. The relationship between the hypertrophic scar and stricture and the other risk factors for anastomotic stricture in these 38 patients was analyzed. @*Results@#Of the 38 patients, eight patients (21.1%) had an anastomotic stricture, and a hypertrophic skin scar was observed in 14 patients (36.8%). Univariate analysis revealed lower BMI and hypertrophic scars as risk factors (p=0.032, p=0.001 respectively).Multivariate analysis revealed a hypertrophic scar as an independent risk factor for an anastomotic stricture (p=0.010, OR=27.06, 95% CI 2.19-334.40). @*Conclusions@#Hypertrophic wound scars can be a risk factor for anastomotic stricture after surgery for esophageal cancer. An earlier prediction of anastomotic stricture by detecting hypertrophic wound healing in patients undergoing esophagectomy may improve the patients’ quality of life and surgical outcomes by earlier treatments.
RESUMEN
Background@#Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection is not differentiated clinically from other respiratory infections, and intensive care units (ICUs) are vulnerable to in-hospital transmission due to interventions inducing respiratory aerosols.This study evaluated the effectiveness of universal SARS-CoV-2 screening in ICUs in terms of screened-out cases and reduction in anxiety of healthcare personnel (HCP).Materials and @*Methods@#This prospective single-armed observational study was conducted in 2 ICUs of a single hospital. The number of patients diagnosed with SARS-CoV-2 infection by the screening program and healthcare workers in ICUs that visited the SARS-CoV-2 screening clinic or infection clinic were investigated. @*Results@#During the 7-week study period, no positive screening case was reported among a total of 142 patients. Among 86 HCP in the ICUs, only 2 HCP sought medical consultation for SARS-CoV-2 infection during the initial 2 weeks. @*Conclusion@#A universal screening program for SARS-CoV-2 infection in ICUs with the coordination of other countermeasures in the hospital was reasonably effective in preventing in-hospital transmission in a pandemic situation and making clinical practices and HCP stable.
RESUMEN
BACKGROUND/AIMS: Socioecomomic factor is an important determinant of access to healthcare and is one of the potential causes of disparities in esophageal cancer care outcomes. The aim of the study was to clarify the association between National health Insurance status (health insurance vs. medicare) as a socioeconomic factor and survival of patients with esophageal cancer who underwent surgical resection. METHODS: Among the 66 patients who underwent surgical resection for esophageal cancer between January 2006 and December 2017, 17 patients (25.8%) were in the medicare group. The data were analyzed to identify clinical manifestations and to compare surgical and oncologic outcomes between the groups. RESULTS: There was no significant difference in the distribution of sex (p=0.13), age (p=0.24), and pathologic stage (p=0.61) between the groups. The length of median hospital stay was significantly shorter in the healthy insurance group (18 days vs. 25 days, p=0.04). In the medicare group, postoperative mortality rates and incidence of postoperative complication were non-significantly higher (11.8% vs. 6.1%, p=0.45, 64.7% vs. 46.7%, p=0.21, respectively). However, pulmonary complication rates, including pneumonia, acute respiratory distress syndorme, and prolonged air leakage was significantly higher in the medicare group (47.1% vs. 18.4%, p=0.02). Five-year disease free survival rate was not different between the two groups (61.0% vs. 54.5%, p=0.68); the 5-year overall survival rate was significantly lower in the medicare group (27.7% vs. 53.7%, p=0.03). CONCLUSIONS: The medicare status of National health insurance could have a negative influence on the overall survival in patients with esophageal cancer who underwent surgery.

OBJECTIVE: We aimed to identify depressive symptom profiles that indicated the presence of depressive disorder and present optimal cut-off sub-scores for depressive symptom profiles for detecting depressive disorder in elderly subjects with chronic physical diseases including diabetes, chronic obstructive pulmonary disease/asthma, and coronary artery disease, using the Patient Health Questionnaire-9 (PHQ-9). METHODS: Two hundred and thirty-one elderly patients with chronic physical diseases were recruited consecutively from a university-affiliated general hospital in South Korea. RESULTS: Greater severities of all 9 depressive symptoms in the PHQ-9 were presented in those with depressive disorder rather than those without depressive disorder. A binary logistic regression modeling presented that little interest [adjusted odds ratio (aOR)=4.648, p<0.001], reduced/increased sleep (aOR=3.269, p<0.001), psychomotor retardation/agitation (aOR=2.243, p=0.004), and concentration problem (aOR=16.116, p<0.001) were independently associated with increased likelihood of having depressive disorder. Receiver operating characteristics (ROC) curve analysis presented that the optimal cut-off value of score on the items for little interest, reduced/increased sleep, psychomotor retardation/agitation and concentration problem (PHQ-9) for detecting depressive disorder was 4 with 61.9% of sensitivity and 91.5% of specificity [area under curve (AUC)=0.937, p<0.001]. CONCLUSION: Our findings suggested that the diagnostic weighting of little interest, reduced/increased sleep, psychomotor retardation/agitation, and concentration problem is needed to detect depressive disorder among the elderly patients with chronic physical diseases.

BACKGROUND: The aim of this study was to report our early experiences with the endovascular repair of ruptured descending thoracic aortic aneurysms (rDTAAs), which are a rare and life-threatening condition. METHODS: Among 42 patients who underwent thoracic endovascular aortic repair (TEVAR) between October 2010 and September 2015, five patients (11.9%) suffered an rDTAA. RESULTS: The mean age was 72.4±5.1 years, and all patients were male. Hemoptysis and hemothorax were present in three (60%) and two (40%) patients, respectively. Hypovolemic shock was noted in three patients who underwent emergency operations. A hybrid operation was performed in three patients. The mean operative time was 269.8±72.3 minutes. The mean total length of aortic coverage was 186.0±49.2 mm. No 30-day mortality occurred. Stroke, delirium, and atrial fibrillation were observed in one patient each. Paraplegia did not occur. Endoleak was found in two patients (40%), one of whom underwent an early and successful reintervention. During the mean follow-up period of 16.8±14.8 months, two patients died; one cause of death was a persistent type 1 endoleak and the other cause was unknown. CONCLUSION: TEVAR for rDTAA was associated with favorable early mortality and morbidity outcomes. However, early reintervention should be considered if persistent endoleak occurs.

OBJECTIVES: Depression is commonly comorbid in elderly patients with physical illness. This study examined the prevalence of depression in the elderly with Diabetes Mellitus (DM). METHODS: Eighty-nine patients, over 60 years old, with DM were enrolled. The medical and psychiatric history, Hamilton Rating Scale for Depression (HDRS), Patient Health Questionnaire-9 (PHQ-9), Geriatric Depression Scale-Short form Korean (GDS-SF-K), and Mini-Mental Status Examination Korean version were examined. RESULTS: The prevalence of depression was estimated as 21.3% (male 4.5% ; female 16.9%) in HDRS, 32.6% (male 9.0% ; female 23.6%) in PHQ-9, and 24.7% (male 5.6% ; female 19.1%) in GDS-SF-K. CONCLUSION: The self-reporting scale, such as GDS-SF-K, PHQ-9 is an effective screening test for depression. The prevalence of elderly depression with DM ranged from 20% to 30%, the prevalence of depression is almost three times more common in women.

BACKGROUND/AIMS: Acute exacerbations in chronic obstructive pulmonary disease may be related to air pollution, of which ozone is an important constituent. In this study, we investigated the protein profiles associated with ozone-induced exacerbations in a smoking-induced emphysema model. METHODS: Mice were divided into the following groups: group I, no smoking and no ozone (NS + NO); group II, no smoking and ozone (NS + O); group III, smoking and no ozone (S + NO); and group IV, smoking and ozone (S + O). Bronchoalveolar lavage, the mean linear intercept (MLI) on hematoxylin and eosin staining, nano-liquid chromatography-tandem mass spectrometry (LC-MS/MS), and Western blotting analyses were performed. RESULTS: The MLIs of groups III (S + NO) and IV (S + O) (45 +/- 2 and 44 +/- 3 microm, respectively) were significantly higher than those of groups I (NS + NO) and II (NS + O) (26 +/- 2 and 23 +/- 2 microm, respectively; p < 0.05). Fourteen spots that showed significantly different intensities on image analyses of two-dimensional (2D) protein electrophoresis in group I (NS + NO) were identified by LC-MS/MS. The levels of six proteins were higher in group IV (S + O). The levels of vimentin, lactate dehydrogenase A, and triose phosphate isomerase were decreased by both smoking and ozone treatment in Western blotting and proteomic analyses. In contrast, TBC1 domain family 5 (TBC1D5) and lamin A were increased by both smoking and ozone treatment. CONCLUSIONS: TBC1D5 could be a biomarker of ozone-induced lung injury in emphysema.

Our study aimed to examine the knowledge and attitude of nursing personnel toward depression in general hospitals of Korea. A total of 851 nursing personnel enrolled at four university-affiliated general hospitals completed self-report questionnaires. Chi-square tests were used to compare the knowledge and attitude of registered or assistant nurses toward depression. In addition, binary logistic regression analysis was used to adjust for the following confounders: age-group and workplace. Registered and assistant nurses differed in their knowledge and attitude toward depression. The proportion of rational and/or correct responses were higher in registered nurses than assistant nurses for the following: constellation of depressive symptoms defined by DSM-IV (adjusted odds ratio [aOR], 3.876; P<0.001); suicide risk in depression recovery (aOR, 3.223; P=0.001) and psychological stress as a cause of depression (aOR, 4.370; P<0.001); the relationship between chronic physical disease and depression (aOR, 8.984; P<0.001); and other items. Our results suggest that in terms of the biological model of depression, the understanding of registered nurses is greater than that of assistant nurses. Moreover, specific psychiatric education programs for nursing personnel need to be developed in Korea. Our findings can contribute to the development of a general hospital-based model for early detection of depression in patients with chronic medical diseases.

Recurrent ventricular arrhythmia can be fatal and cause serious complications, particularly when it is caused immediately after an operation. Incorrect placement of a Swan-Ganz catheter can trigger life-threatening ventricular arrhythmia, but even intensive care specialists tend to miss this fact. Here, we report a case of recurrent ventricular arrhythmia causing a severe hemodynamic compromise; the arrhythmia was induced by a severely angulated Swan-Ganz catheter. The recurrent ventricular arrhythmia was not controlled by any measures including repositioning of the catheter, until the complete removal of the Swan-Ganz catheter. It is necessary to keep in mind that the position of the pulmonary artery catheter should be promptly checked if there is intractable recurrent ventricular arrhythmia.

A 61-year-old man was diagnosed with aortic stenoinsufficiency with periannular abscess, which involved the aortic root of noncoronary sinus (NCS) that invaded down to the central fibrous body, whole membranous septum, mitral valve (MV), and tricuspid valve (TV). The open complete debridement was executed from the aortic annulus at NCS down to the central fibrous body and annulus of the MV and the TV, followed by the left ventricular outflow tract reconstruction with implantation of a mechanical aortic valve by using a leaflet of the half-folded elliptical bovine pericardial patch. Another leaflet of this patch was used for the repair of the right atrial wall with a defect and the TV.

BACKGROUND: There are few comparative studies about the optimal method of pneumatic compression to prevent deep vein thrombosis (DVT). The aim of this prospective randomized study was to compare venous hemodynamic changes and their clinical influences between two graded sequential compression groups (an alternate sequential compression device [ASCD] vs. a simultaneous sequential compression device [SSCD]). METHODS: In total, 34 patients (68 limbs) undergoing knee and spine operations were prospectively randomized into two device groups (ASCD vs. SSCD groups). Duplex ultrasonography examinations were performed on the 4th and 7th postoperative days for the detection of DVT and the evaluation of venous hemodynamics. Continuous data for the two groups were analyzed using a two-tailed, unpaired t-test. Relative frequencies of unpaired samples were compared using Fisher exact test. Mixed effects models that might be viewed as ANCOVA models were also considered. RESULTS: DVT developed in 7 patients (20.6%), all of whom were asymptomatic for isolated calf DVTs. Two of these patients were from the ASCD group (11.8%) and the other five were from the SSCD group (29.4%), but there was no significant difference (p = 0.331). Baseline peak velocity, mean velocity, peak volume flow, and total volume flow were enhanced significantly in both device groups (p < 0.001). However, the degrees of flow and velocity enhancement did not differ significantly between the groups. The accumulated expelled volumes for an hour were in favor of the ASCD group. CONCLUSIONS: Both graded sequential compression devices showed similar results both in clinical and physiological efficacies. Further studies are required to investigate the optimal intermittent pneumatic compression method for enhanced hemodynamic efficacy and better thromboprophylaxis.

For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.

Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor. Herein, we report the case of a 52-year-old male patient who had postprandial abdominal distension and right upper quadrant abdominal pain. The abdominal computed tomography (CT) angiogram showed an IVC mass extending from the infrahepatic to the suprarenal inferior vena cava. The radiologic findings were suggestive of an IVC leiomyosarcoma. Surgical resection and reconstruction with a cryopreserved homograft were performed. The follow-up abdominal CT angiogram revealed the patient to be disease-free 6 months after surgery with patency of the IVC and renal vein.

BACKGROUND: Hemoptysis due to pulmonary tuberculosis (TB) frequently develops in Korea where the prevalence of TB is intermediate. The effect of bronchial artery embolization (BAE) on the control of massive hemoptysis has been well known. This study is designed to identify the risk factors contributing to rebleeding after BAE in patients with TB. METHODS: We retrospectively evaluated risk factors and the time for rebleeding after BAE in 72 patients presenting with hemoptysis. RESULTS: The overall immediate success rate of BAE was 93.1% (67 of 72 patients). Of the 29 patients (40.3%) who showed rebleeding after BAE, 13 patients experienced rebleeding within 1 month, and 14 patients between 1 month to 1 year. The existence of a shunt in angiographic finding, aspergilloma, and diabetes mellitus were risk factors of rebleeding after BAE in multivariate analysis. CONCLUSION: BAE was very effective for obtaining immediate bleeding control in hemoptysis associated with active TB or post-TB sequelae. It is important to observe whether or not rebleeding occurs up to 1 year of BAE especially in TB patients with aspergilloma, DM, or a shunt. Even rebleeding can be managed well by second BAE.

BACKGROUND/AIMS: Cyclophosphamide (CP) is a promising treatment for severe cases of paraquat (PQ) poisoning. We investigated the effective dose of CP for mitigating PQ-induced lung injury. METHODS: Adult male Sprague-Dawley rats were allocated into five groups: control, PQ (35 mg/kg, intraperitoneal injection), and PQ + CP (1.5, 15, or 30 mg/kg). The dimensions of lung lesions were determined using X-ray microtomography (micro-CT), and histological changes and cytokine levels were recorded. RESULTS: The micro-CT results showed that 15 mg/kg CP was more effective than 1.5 mg/kg CP for treating PQ-induced lung injury. At a dose of 1.5 mg/kg, CP alleviated the histological evidence of inflammation and altered superoxide dismutase activity. Using 15 mg/kg CP reduced the elevated catalase activity and serum transforming growth factor (TGF)-beta1 level. CONCLUSIONS: A CP dose of > 15 mg/kg is effective for reducing the severity of PQ-induced lung injury as determined by histological and micro-CT tissue examination, possibly by modulating antioxidant enzyme and TGF-beta1 levels.

The geriatric patients with chronic physical diseases are frequently associated with the continuous clusters of depression including nonpathological sadness, subsyndromal depression, minor depressive disorder, and major depressive disorder. Because of the complex and reciprocal relationships among depression, elderly, and chronic physical diseases, screening approaches with specific nosological methods should be needed in the realm of early detection of depression. Cognitive decline is frequently manifested in geriatric depression with medical or neurological diseases. Also, somatic symptoms of depression or emotional symptoms of physical diseases can play a role as a hampering factor in the early detection of depression. Furthermore, after-care has been regarded as an essential factor of depression screening in the geriatric patients with chronic physical diseases. We reviewed the most popular examples of integrated medicine for depression in primary care. Thus, we propose a general hospital-based model for early detection of depression which includes favorable response loop between screening and therapeutic intervention. Our model can be a basis for evidence-based detection and after-care for depression in the geriatric patients with chronic medical diseases.

In patients with advanced non-small cell lung cancer harboring epidermal growth factor receptor (EGFR) mutations, the epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are used as first treatment option. Because adenosquamous carcinoma (ASC) is a rare histologic subtype, evidences about EGFR-TKIs as first treatment option for advanced ASC are lacking. We report a case of an advanced ASC patient with the EGFR mutation, who showed good responses during 4-month treatment with gefitinib. And we will review about a necessity of EGFR mutation test and efficacy of EGFR-TKIs in ASC patients from the recent studies.

To quantify the reduction in workload during intra-aortic balloon pump (IABP) therapy, indirect parameters are used, such as the mean arterial pressure during diastole, product of heart rate and peak systolic pressure, and pressure-volume area. Therefore, we investigated the cardiac energy consumption during IABP therapy using a cardiac electromechanics model. We incorporated an IABP function into a previously developed electromechanical model of the ventricle with a lumped model of the circulatory system and investigated the cardiac energy consumption at different IABP inflation volumes. When the IABP was used at inflation level 5, the cardiac output and stroke volume increased 11%, the ejection fraction increased 21%, the stroke work decreased 1%, the mean arterial pressure increased 10%, and the ATP consumption decreased 12%. These results show that although the ATP consumption is decreased significantly, stroke work is decreased only slightly, which indicates that the IABP helps the failed ventricle to pump blood efficiently.
