Objective:
High-quality intensive care, including targeted temperature management (TTM) for patients with postcardiac arrest syndrome, is a key element for improving outcomes after out-of-hospital cardiac arrest (OHCA). We aimed to assess the status of postcardiac arrest syndrome care, including TTM and 6-month survival with neurologically favorable outcomes, after adult OHCA patients were treated with TTM, using data from the Korean Hypothermia Network prospective registry.
Methods:
We used the Korean Hypothermia Network prospective registry, a web-based multicenter registry that includes data from 22 participating hospitals throughout the Republic of Korea. Adult comatose OHCA survivors treated with TTM between October 2015 and December 2018 were included. The primary outcome was neurological outcome at 6 months.
Results:
Of the 1,354 registered OHCA survivors treated with TTM, 550 (40.6%) survived 6 months, and 413 (30.5%) had good neurological outcomes. We identified 839 (62.0%) patients with preClinsumed cardiac etiology. A total of 937 (69.2%) collapses were witnessed, shockable rhythms were demonstrated in 482 (35.6%) patients, and 421 (31.1%) patients arrived at the emergency department with prehospital return of spontaneous circulation. The most common target temperature was 33°C, and the most common target duration was 24 hours.
Conclusion
The survival and good neurologic outcome rates of this prospective registry show great improvements compared with those of an earlier registry. While the optimal target temperature and duration are still unknown, the most common target temperature was 33°C, and the most common target duration was 24 hours.

Background:
s: The severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has spread worldwide. Cardiac injury after SARS-CoV-2 infection is a major concern. The present study investigated impact of the biomarkers indicating cardiac injury in coronavirus disease 2019 (COVID-19) on patients' outcomes.
Methods:
This study enrolled patients who were confirmed to have COVID-19 and admitted at a tertiary university referral hospital between February 19, 2020 and March 15, 2020. Cardiac injury was defined as an abnormality in one of the following result markers: 1) myocardial damage marker (creatine kinase-MB or troponin-I), 2) heart failure marker (N-terminal-pro B-type natriuretic peptide), and 3) electrical abnormality marker (electrocardiography). The relationship between each cardiac injury marker and mortality was evaluated. Survival analysis of mortality according to the scoring by numbers of cardiac injury markers was also performed.
Results:
A total of 38 patients with COVID-19 were enrolled. Twenty-two patients (57.9%) had at least one of cardiac injury markers. The patients with cardiac injuries were older (69.6 ± 14.9 vs. 58.6 ± 13.9 years old, P = 0.026), and were more male (59.1% vs. 18.8%, P = 0.013).They showed lower initial oxygen saturation (92.8 vs. 97.1%, P = 0.002) and a trend toward higher mortality (27.3 vs. 6.3%, P = 0.099). The increased number of cardiac injury markers was significantly related to a higher incidence of in-hospital mortality which was also evidenced by Kaplan-Meier survival analysis (P = 0.008).
Conclusion
The increased number of cardiac injury markers is related to in-hospital mortality in patients with COVID-19.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

BACKGROUND: Stenotrophomonas maltophilia is a gram-negative bacillus and a nosocomial pathogen in immunocompromised patients. Trimethoprim/sulfamethoxazole (TMP/SMX) is the drug of choice for treating S. maltophilia infection; however, resistance to TMP/SMX is increasing. In this study, we investigated the relationship between the incidence of TMP/SMX resistance and the presence of sul genes and mobile elements. METHODS: A total of 120 S. maltophilia isolates were collected from 3 university hospitals between April 2007 and April 2009. Antimicrobial susceptibilities were determined using the disk diffusion method. PCR and DNA sequencing were conducted for the detection of sul1, sul2, class 1 integron, and ISCR2 element. Repetitive extragenic palindromic sequence-based PCR (REP-PCR) was carried out to evaluate the genetic relatedness. RESULTS: The TMP/SMX-resistant (R) isolates harbored a significantly higher proportion of sul1 gene and class 1 integron than TMP/SMX-susceptible (S) isolates (P<0.001). Seventeen of 28 isolates with sul1 also had a class 1 integron, but none of the isolates without sul1 had a class 1 integron. The identified gene cassettes within class 1 integrons include aacA4, aadA1, aac6'-II, and qac. None of the 120 isolates carried sul2, glmM, or ISCR2 element. REP-PCR did not show any genetic relatedness among the isolates. CONCLUSIONS: In Korea, the resistance of S. maltophilia isolates to TMP/SMX is due to sul1 within a class 1 integron rather than to sul2. The class 1 integron also harbors multiple antibiotic resistance genes in addition to sul1, and therefore it could mediate multidrug resistance in S. maltophilia.

BACKGROUND: Acinetobacter baumannii is an aerobic, gram-negative, glucose-nonfermenting bacterium, which has emerged as a serious opportunistic pathogen. In recent years, the increasing instance of carbapenem-resistant A. baumannii producing metallo-beta-lactamases (MBLs) or OXAtype beta-lactamases is causing a serious clinical problem. In this study, we investigated the prevalence of Ambler class A, B, and D beta-lactamases and their extended-spectrum derivatives in carbapenem-resistant A. baumannii isolates. METHODS: A total of 31 consecutive, non-duplicate, carbapenem-resistant A. baumannii were isolated from three university hospitals in the Chungcheong province of Korea. The modified Hodge and inhibitor-potentiated disk diffusion tests were conducted for the screening of carbapenemase and MBL production, respectively. PCR and DNA sequencing were performed for the detection of beta-lactamase genes. We also employed the enterobacterial repetitive intergenic consensus (ERIC)-PCR method for the epidemiologic study. RESULTS: Twenty-three of 31 isolates harbored bla(OXA-2) (51.6%), bla(OXA-23) (22.6%), bla(IMP-1) (48.4%),and bla(VIM-2) (3.2%). All of the OXA-2-producing strains also evidenced MBLs. The strains that harbored bla(OXA-23) were isolated only in hospital C, and only in a limited fashion. The ERIC-PCR pattern of the five OXA-23 strains indicated that the isolates were closely related in terms of clonality. The six strains producing IMP-1 isolated from hospital A were confirmed to be identical strains. CONCLUSIONS: A. baumannii strains harboring IMP-1 or OXA-type beta-lactamases are currently widely distributed throughout the Chungcheong province of Korea. The most notable finding in this study was that a bla(OXA-2)-producing A. baumannii harboring MBL, which has not been previously reported, can also lead to outbreaks.

PURPOSE: A catheter-associated urinary tract infection, which frequently occurs in patients with an indwelling Foley catheter, can cause serious morbidity or mortality. Recently, antibiotic coated Foley catheters, to prevent catheter-associated urinary tract infections, have become commercially available. This study investigated the long-term effects of the use of antibiotic-coated Foley catheters on biofilm formations. MATERIALS AND METHODS: Silicone Foley or antibiotic-coated Foley catheters were indwelled in 72 patients with a neurogenic bladder. Each catheter was removed 1, 3, 5, 7, 14 and 28 days after insertion. The cell densities of the biofilm bacteria were evaluated by counting the number of colonies on plate cultures. The biofilm formations on the catheters were evaluated by scanning electron microscopy. The inner surface morphology of the catheter was imaged by field emission scanning electron microscopy (Philips-XL20SFEG), at 10kV, following gold sputtering for electrical conductance. Six catheters were studied in each group, and the means calculated for comparisons. RESULTS: Thick bacterial biofilms were observed on both the antibiotic- coated and silicone Foley catheters 7 days after insertion. There were no significant differences in the cell densities of the biofilm bacteria between the two types of catheter during days 7-28 after insertion (p<0.05). Two to three species of bacteria were isolated from the catheters in each patient; the most common species were Pseudomonas, Klebsiella, Serratia, Proteus species and Escherichia coli. CONCLUSIONS: The antibiotic-coated Foley catheters showed no preventive effects on the biofilm formations after 7 days of indwelling compared with the silicone Foley catheters. Our data suggest that the routine use of antibiotic-coated Foley catheters to prevent catheter-associated infection in patients with a neurogenic bladder is not reasonable. The emergence of resistance associated with antibiotic-coated catheters should be evaluated.

PURPOSE: Although subintimal angioplasty (SIA) has been advocated to treat chronic lower extremity arterial occlusions, numerous reports have described differences in its results. We evaluated the effect of SIA in a group of patients with severe lower extremity arterial occlusive disease. METHOD: During a 5-month period, 6 limbs in 4 patients with arterial occlusions (mean length, 17.7 cm; range, 9 to 27 cm) were treated with SIA. Three limbs had gangrene, and all patients had resting pain. There were two external iliac-superficial femoral, two superficial femoral-popliteal and two femoral-popliteal-tibial artery lesions. With fluoroscopic guidance, via an antegrade common femoral artery puncture, a subintimal dissection plane was created across the occlusion with standard hydrophilic guidewire and catheter. The arterial lumen was reentered distal to the occlusion, and the recanalized segment was balloon (3 to 6 mm) dilated. RESULT: SIA was technically successful in all 6 limbs (100%). Pain was completely resolved and all areas of gangrene were healed. The mean increase in ankle-brachial index after SIA was 0.51 (range, 0.25 to 0.71). There was no significant complication related with SIA and all arteries were patent during 3.6-months mean follow-up period. CONCLUSION: SIA for long occlusions of the crural arteries is safe and effective and can be an excellent alternative to reconstructive surgery in elderly and frail patients.

PURPOSE: To estimate the influences of pain and urinary symptoms on quality of life and determine the item that has the most predicting ability for quality of life in young men with chronic prostatitis-like symptoms. MATERIALS AND METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. of 28,841 men aged 20 years dwelling in the community, 16,321 men(a response rate 56.6%) completed self-administered questionnaires. A total of 1,057men who complained symptoms suggestive of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined by the logistic regression analysis. The receiver operating characteristic(ROC) curve was used to provide the predicting ability of each item quality of life. RESULTS: In multivariate analysis, pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, and pain contributed more than urinary symptoms. Among items of pain and urinary symptoms, pain severity had the most predicting ability for impact, overall quality of life and quality of life impact domain. The areas under the ROC curves for impact, overall quality of life and quality of life impact domain were 71.3%, 69.3% and 67.0%, respectively. CONCLUSIONS: Urinary symptoms as well as pain may be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influencing factor for quality of life in this population.

AIMTo help clarifying the possibility of connective-tissue diseases in men with penile or testicular prostheses.
METHODSEight patients underwent inflatable penile prostheses and 15, testicular prostheses consented to the study. Their medical records were reviewed and a follow-up interview and physical and serological examinations were performed.
RESULTSIn patients with penile prostheses, there was no abnormal antinuclear antibody (ANA) or IgM elevation. The serum levels of the rheumatoid factor (RF), C4, IgA and IgG were abnormal in one patient, and the levels of erythrocyte sedimentation rate (ESR) and C3, abnormal in two. Four had elevated IgE. In patients with testicular prostheses, there was no abnormal RF, ANA or IgM. The serum levels of ESR and IgA were abnormal in two, and three had abnormal C4, ten abnormal C3, and eleven decreased IgG. All had increased IgE. Men with penile prostheses had higher serum levels of IgG and IgM than those with testicular prostheses (P=0.001, P=0.016, respectively). The rates of abnormal values of IgE and IgG were higher in men with testicular prostheses than in men with penile prostheses (P=0.008, P=0.009, respectively). Physical examination was normal in all patients and nobody had documented symptoms pertinent to connective-tissue diseases.
CONCLUSIONOur findings suggest that the risk of connective-tissue diseases is not higher in patients wearing prostheses as the ANA is negative and there is no apparent manifestation suggestive of connective-tissue diseases.

Ascites is a rare complication of multiple myeloma. When it develops, it is usually associated with extensive liver infiltration with plasma cells, infectious peritonitis or myelomatous peritoneal infiltration. Ascites caused by peritoneal infiltration is even less frequent than others. The majority of previously reported cases were characterized by an IgA paraprotein and lack of skeletal lesions. This rare extramedullary complication of myeloma has been unresponsive to therapy and rapidly fatal. Therefore, it is important to recognize myeloma as a cause of ascites and the presence of ascites heralds a poor prognosis of myeloma. We recently experienced a case of myeloma with ascites and reviewed the relevant literature of human myeloma presenting with the triad of ascites, relative or absolute sparing of the skeleton, and an IgA paraprotein. A 76-year-old man was presented with ascites early in the course of myeloma. He had no evidence of intra-abdominal plasmacytoma and skeletal lesions. Myelomatous ascites was demonstrated by the monoclonal immunoglobulin of IgA type in ascitic fluid. He was treated by plasmapheresis due to hyperviscosity syndrome and VAD combination chemotherapy. He was discharged with the improved clinical condition.
