RESUMEN
BACKGROUND: Obesity is often considered a risk factor for cardiovascular disease, but recent studies have shown conflicting results regarding the effect of BMI on the prognosis of coronary artery disease (CAD). This study aimed to evaluate the relationship between BMI and clinical outcomes of CAD according to sex in a Korean population. METHODS: A total of 3476 patients with a significant CAD who underwent percutaneous coronary intervention (PCI) were enrolled. Patients were classified as follows according to BMI using the Asia-Pacific cutoff points: underweight (<18.5â kg/m 2 ), normal weight (18.5-22.9â kg/m 2 ), overweight (23.0-24.9â kg/m 2 ) and obese (≥25â kg/m 2 ) patients. Underweight and normal weight patients were further categorized into the lower BMI group, whereas overweight and obese patients were categorized into the higher BMI group. The primary endpoint was all-cause mortality. RESULTS: Among women, the higher BMI group showed poor clinical features in the prevalence of hypertension and chest pain presentation, and among men, the higher BMI group had a significantly lower rate of chronic renal failure. At the end of the follow-up period (median 53.5 months), the all-cause mortality rate was lower in the higher BMI group in men, and cardiovascular death and stroke rates were significantly lower in the higher BMI group in women. CONCLUSION: In Korean CAD patients treated with PCI, inverse correlations were observed between the clinical outcomes and BMI, but there were differences between men and women.

The authors evaluated the efficacy, safety, and characteristics of patients who respond well to standard dose triple combination therapy including chlorthalidone 25 mg with telmisartan 80 mg plus amlodipine 5 mg in hypertensive patients. This is a multicenter, double-blind, active-controlled, phase 3, randomized trial. Patients are randomized to triple combination (telmisartan 40 mg/amlodipine 5 mg/chlorthalidone 12.5 mg, TEL/AML/CHTD group) or dual combination (telmisartan 40 mg/amlodipine 5 mg, TEL/AML group) treatment and then dose up titration to TEL 80/AML5/CHTD25mg and TEL80/AML5, respectively. The primary endpoint is the change of mean sitting systolic blood pressure (MSSBP) at week 8. A Target BP achievement rate, a response rate, and the safety endpoints are also evaluated. Total 374 patients (mean age = 60.9 ± 10.7 years, male = 78.3%) were randomized to the study. The baseline MSSBPs/diastolic BPs were 149.9 ± 12.2/88.5 ± 10.4 mm Hg. After 8 weeks treatment, the change of MSSBPs at week 8 are -19.1 ± 14.9 mm Hg (TEL/AML/CHTD) and -11.4 ± 14.7 mm Hg (TEL/AML) (p < .0001). The achievement rates of target BP (53.8% vs. 37.8%, p = .0017) and responder rate (54.8% vs. 35.6%, p = .0001) at week 8 were significantly higher in TEL/AML/CHTD. There are no serious adverse event and no one discontinued medication due to adverse event. Among the TEL 80/AML5/CHTD25mg treatment group, patients of female or age ≥ 65 years old showed higher rate of target BP achievement than relatively young male. (61.4 vs. 46.8%, p = .042) Our study showed standard dose triple combination of telmisartan 80 mg/amlodipine 5 mg/chlorthalidone 25 mg is efficacious and safe in treatment of primary hypertension. Target BP achievement with triple therapy would be facilitated in female or old age.

BACKGROUND/AIMS: The Genoss DES™ is a novel, biodegradable, polymer-coated, sirolimus-eluting stent with a cobalt- chromium stent platform and thin strut. Although the safety and effectiveness of this stent have been previously investigated, real-world clinical outcomes data are lacking. Therefore, the aim of this prospective, multicenter trial was to evaluate the clinical safety and effectiveness of the Genoss DES™ in all-comer patients undergoing percutaneous coronary intervention. METHODS: The Genoss DES registry is a prospective, single-arm, observational trial for evaluation of clinical outcomes after Genoss DES™ implantation in all-comer patients undergoing percutaneous coronary intervention from 17 sites in South Korea. The primary endpoint was a device-oriented composite outcome of cardiac death, target vessel-related myocardial infarction (MI), and clinically driven target lesion revascularization (TLR) at 12 months. RESULTS: A total of 1,999 patients (66.4 ± 11.1 years of age; 72.8% male) were analyzed. At baseline, 62.8% and 36.7% of patients had hypertension and diabetes, respectively. The implanted stent number, diameter, and length per patient were 1.5 ± 0.8, 3.1 ± 0.5 mm, and 37.0 ± 25.0 mm, respectively. The primary endpoint occurred in 1.8% patients, with a cardiac death rate of 1.1%, target vessel-related MI rate of 0.2%, and clinically driven TLR rate of 0.8%. CONCLUSION: In this real-world registry, the Genoss DES™ demonstrated excellent safety and effectiveness at 12 months among all-comer patients undergoing percutaneous coronary intervention. These findings suggest that the Genoss DES™ may be a viable treatment option for patients with coronary artery disease.

Background: Moderate-intensity statin role with ezetimibe combination therapy following percutaneous coronary intervention (PCI) has not been thoroughly investigated, particularly compared to high-intensity statin monotherapy. We aimed to investigate the effect of ezetimibe combination with moderate-intensity statin in patients with atherosclerotic cardiovascular disease following PCI. Methods: This was a post-hoc analysis of a subset of patients who underwent PCI in the RACING trial. At 26 centres in South Korea, patients with atherosclerotic cardiovascular disease (ASCVD) were randomly assigned to receive either moderate-intensity statin with ezetimibe combination therapy (rosuvastatin 10 mg with ezetimibe 10 mg) or high-intensity statin monotherapy (rosuvastatin 20 mg). The prespecified endpoints of the RACING trial were used. The primary endpoint was the 3-year composite of cardiovascular death, major cardiovascular events, and nonfatal stroke. Event rates between the two groups were compared using log-rank tests, and hazard ratios (HR) with 95% confidence intervals (CI) were estimated using Cox regression analysis. Consistent with the RACING trial, the primary and secondary efficacy endpoints were evaluated using an intention-to-treatment approach, and the safety endpoints were assessed in the safety population. The RACING trial was registered at ClinicalTrials.gov (NCT03044665). Findings: Between Feb 14, 2017, and Dec 18, 2018, 3780 participants were enrolled in the RACING trial. Prior history of PCI was found in 2497 patients (67%, median 64 years, 79% male), and was associated with higher rates of the primary endpoint (hazard ratio [HR], 1.34; 95% confidence interval [CI], 1.06-1.69; p = 0.014). Among patients with prior PCI, moderate-intensity statin therapy with ezetimibe combination versus high-intensity statin therapy did not increase the risk of the primary endpoint (HR, 0.95; 95% CI, 0.74-1.24; p = 0.781). The proportion of patients with low-density lipoprotein cholesterol (LDL-C) <70 mg/dL at 1, 2, and 3 years was 74%, 76%, and 73%, respectively, in the combination therapy group, and was significantly higher than that in the high-intensity statin monotherapy group (57%, 62%, and 59%, respectively, all p < 0.001). Discontinuation of lipid-lowering drugs occurred less frequently in the combination group (4.2% vs. 7.6%, p = 0.001). Interpretation: The effects of ezetimibe combination therapy observed in the RACING trial were consistently preserved among patients with ASCVD following PCI. Ezetimibe combination could be considered as a suitable therapeutic strategy to achieve strict control of LDL-C and reduce drug intolerance in patients who underwent PCI.

RESUMEN
We compared the efficacy and safety of third-standard-dose triple and third-standard-dose dual antihypertensive combination therapies in patients with mild to moderate hypertension. This was a phase II multicenter, randomized, double-blind, parallel-group trial. After a 4-week placebo run-in period, 245 participants were randomized to the third-dose triple combination (ALC group; amlodipine 1.67 mg + losartan potassium 16.67 mg + chlorthalidone 4.17 mg) or third-dose dual combination (AL group; amlodipine 1.67 mg + losartan potassium 16.67 mg, LC group; losartan potassium 16.67 mg + chlorthalidone 4.17 mg, AC group; amlodipine 1.67 mg + chlorthalidone 4.17 mg) therapy groups and followed up for 8 weeks. The mean systolic blood pressure (BP) reduction was -18.3 ± 13.2, -13.0 ± 13.3, -16.3 ± 12.4, and -13.8 ± 13.2 mmHg in the ALC, AL, LC, and AC groups, respectively. The ALC group showed significant systolic BP reduction compared to the AL and AC groups at weeks 4 (P = .010 and P = .018, respectively) and 8 (P = .017 and P = .036, respectively). At week 4, the proportion of systolic BP responders was significantly higher in the ALC group (42.6%) than in the AL (22.0%), LC (23.3%), and AC (27.1%) groups (P = .013, P = .021, and P = .045, respectively). At week 8, the proportion of systolic and diastolic BP responders was significantly higher in the ALC group (59.7%) than in the AL (39.3%) and AC (42.4%) groups (P = .022 and P = .049, respectively) at week 8. Third-standard-dose triple antihypertensive combination therapy demonstrated early effective BP control compared to third-standard-dose dual combination therapies, without increasing adverse drug reactions in patients with mild-to-moderate hypertension.

The incidence and impact of malnutrition on acute coronary syndrome (ACS) remain unclear. This study aimed to evaluate the prevalence, clinical relevance, and prognostic outcomes of malnutrition in patients with ACS treated with percutaneous coronary intervention. This retrospective study included 1930 consecutive patients with ACS undergoing percutaneous coronary intervention and assessed their nutritional status using 3 scoring systems: Controlling Nutritional Status score, nutritional risk index (NRI), and prognostic nutritional index (PNI). The primary endpoint was all-cause mortality. The Controlling Nutritional Status, NRI, and PNI scores showed that 5.2%, 17.5%, and 3.9% of patients were moderately or severely malnourished, respectively. During a median follow-up of 67.2 months (interquartile range: 46.8-88.5 months), 74 (3.8%) patients died. Malnutrition was associated with a significantly increased risk for all-cause mortality compared with good nutrition (adjusted hazard ratios for moderate and severe malnutrition, respectively: 5.65 [95% confidence interval: 3.27-9.78] and 15.26 [7.50-31.05] for the NRI score, 5.53 [2.10-14.49] and 11.08 [5.69-21.59] for the PNI; P < .001). The current findings demonstrated that malnutrition is prevalent among patients with ACS and is closely associated with increased mortality. Further study is needed to evaluate the effects of nutritional interventions on the outcomes of patients with ACS.

BACKGROUND: Bone marrow (BM) suppression is one of the most common side effects of radiotherapy and the primary cause of death following exposure to irradiation. Despite concerted efforts, there is no definitive treatment method available. Recent studies have reported using mesenchymal stromal cells (MSCs), but their therapeutic effects are contested. AIM: We administered and examined the effects of various amounts of adipose-derived MSCs (ADSCs) in mice with radiation-induced BM suppression. METHODS: Mice were divided into three groups: Normal control group, irradiated (RT) group, and stem cell-treated group following whole-body irradiation (WBI). Mouse ADSCs (mADSCs) were transplanted into the peritoneal cavity either once or three times at 5 × 105 cells/200 µL. The white blood cell count and the levels of, plasma cytokines, BM mRNA, and BM surface markers were compared between the three groups. Human BM-derived CD34+ hematopoietic progenitor cells were co-cultured with human ADSCs (hADSCs) or incubated in the presence of hADSCs conditioned media to investigate the effect on human cells in vitro. RESULTS: The survival rate of mice that received one transplant of mADSCs was higher than that of mice that received three transplants. Multiple transplantations of ADSCs delayed the repopulation of BM hematopoietic stem cells. Anti-inflammatory effects and M2 polarization by intraperitoneal ADSCs might suppress erythropoiesis and induce myelopoiesis in sub-lethally RT mice. CONCLUSION: The results suggested that an optimal amount of MSCs could improve survival rates post-WBI.
RESUMEN
We sought to investigate the psychosocial characteristics of patients with uncontrolled hypertension and examine factors that influence blood pressure (BP) control. A total of 1011 patients with uncontrolled hypertension were enrolled in 13 tertiary hospitals. Uncontrolled hypertension was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg despite on antihypertensive therapy. Socio-demographics, anthropometrics, behavioral risk factors, medication pattern, adherence, and measures of health-related quality of life (HRQoL; EuroQol 5D visual analog scale [EQ-5D VAS]) were assessed at baseline and during follow-up visits (3 and 6 months). Patients were divided into 2 groups based on BP control status at 6 months (controlled group [n = 532] vs uncontrolled group [n = 367]). There were no differences in clinical characteristics except the proportion of smokers and baseline BP between patients with controlled BP and uncontrolled BP. At 6 months, the adherence of antihypertensive medication did not differ between the groups but the proportion of combination therapy with ≥3 antihypertensives was significantly higher in patients with uncontrolled BP. EQ-5D VAS at follow-up was significantly lower in patients with uncontrolled BP despite similar baseline values. Multivariate logistic regression analysis revealed that EQ-5D VAS at follow-up significantly correlated with BP control. Patients with worse HRQoL had higher Charlson Comorbidity Index and higher proportion of taking ≥3 antihypertensives, but medication adherence was similar to those with better HRQoL. These findings suggest that along with pharmacologic intervention of hypertension, management of comorbid conditions or psychological support might be helpful for optimizing BP control in patients with uncontrolled hypertension.

The American College of Cardiology and American Heart Association (ACC/AHA) guidelines identified four statin benefit groups on the basis of atherosclerotic cardiovascular disease risk reduction and proposed statin therapy by evidence-based intensity. Although these guidelines used randomized controlled trials with hard outcomes as exclusive evidence for its recommendations, a limited number of studies conducted in Asian countries makes its application of treatment strategy, intensity, and statin doses uncertain in these population. This prospective, multicenter study aimed to evaluate the efficacy of rosuvastatin 10 mg in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines in the Korean population. The primary endpoint was percentage reduction in low-density lipoprotein (LDL) cholesterol. Secondary endpoints were percentage reduction in other lipids and achievement of ≥50% reduction in LDL cholesterol. Rosuvastatin 10 mg lowered LDL cholesterol by 61.4 mg/dL, a 44.9% decrease from baseline after eight weeks. Reduction of LDL cholesterol ≥50% was achieved in 46.3% of patients. Rosuvastatin 10 mg was generally well tolerated. In the Korean population, rosuvastatin 10 mg was favorable and tolerant in lowering LDL cholesterol in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines.
RESUMEN
PURPOSE: We evaluated the dose-responsiveness, efficacy, and safety of low-dose triple antihypertensive combination therapies in patients with mild-to-moderate hypertension. PATIENTS AND METHODS: After a 1 to 2-week placebo run-in period, 248 patients were randomized to the half-dose triple combination (amlodipine 2.5 mg + losartan 25 mg + chlorthalidone 6.25 mg), third-dose triple combination (amlodipine 1.67 mg + losartan 16.67 mg + chlorthalidone 4.17 mg), quarter-dose triple combination (amlodipine 1.25 mg + losartan 12.5 mg + chlorthalidone 3.13mg), amlodipine 10mg, amlodipine 5mg, losartan 100mg, and placebo groups for 8 weeks. The primary outcome was the mean change in systolic blood pressure (SBP) from baseline to week 8. RESULTS: The placebo-corrected SBP reductions of the half-dose, third-dose, quarter-dose combination, amlodipine 10 mg, amlodipine 5 mg and losartan 100 mg treatments were -17.2, -19.5, -14.9, -18.5, -11.3 and -9.9 mmHg, respectively. The BP control and response rates were significantly higher in the half-dose, third-dose, and quarter-dose combination groups than in the placebo group (all p < 0.01). Despite no intergroup differences in study drug-related adverse events, ankle circumference increased significantly in the amlodipine group compared to those in the combination treatment groups. The quarter-dose combination, amlodipine 5 mg, and losartan 100 mg groups showed similar SBP reduction and BP response rates. The SBP reduction and BP response rate in the third-dose and half-dose combination groups were not significantly different from those in the amlodipine 10 mg group but superior to those in the losartan 100 mg group. CONCLUSION: Low-dose triple combination therapies could be effective as antihypertensive therapies. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03897868.

There are some similarities in clinical features between Takotsubo cardiomyopathy during the peripartum period (PTCM) and peripartum cardiomyopathy (PPCM). Both conditions present as acute heart failure and decreased left ventricular (LV) ejection fraction in the peripartum period in previously heart-healthy women. The present study aimed to evaluate the differences in clinical features and outcomes between PTCM and PPCM. Between January 2004 and December 2016, 37 consecutive patients who demonstrated LV dysfunction during the peripartum period without previous heart disease were recruited retrospectively. The clinical, laboratory, and echocardiographic data of these patients were comprehensively reviewed. Twenty-one (57%) and 16 (43%) patients were classified into PPCM and PTCM groups, respectively, based on echocardiographic findings. The initial LV ejection fraction did not differ significantly between the 2 groups. However, all patients with PTCM showed complete recovery of LV ejection fraction at the 1-month follow-up. However, among 20 patients with PPCM who underwent 1-month echocardiography, only 6 (30%) showed complete recovery of LV ejection fraction at the 1-month follow-up. At the 12-month follow-up, only 10 patients showed complete recovery of LV ejection fraction. The incidence of PTCM was much higher than expected. Although LV dysfunction was similar at the initial diagnosis, the prognosis of LV recovery was more favorable in PTCM than in PPCM. Therefore, physicians should differentiate these two diseases entities, although they have several similarities in acute LV dysfunction.

BACKGROUND: To determine whether the effectiveness and safety of fixed-dose combinations (FDCs) of amlodipine orotate/valsartan (AML/VAL) 5/160âmg are noninferior to those of valsartan/hydrochlorothiazide (VAL/HCTZ) 160/12.5âmg in hypertensive patients with inadequate response to valsartan 160âmg monotherapy. METHODS: This 8-week, active-controlled, parallel-group, fixed-dose, multicenter, double-blind randomized controlled, and noninferiority trial was conducted at 17 cardiovascular centers in the Republic of Korea. Eligible patients had mean sitting diastolic blood pressure (msDBP) ≥90âmmâHg despite monotherapy with valsartan 160âmg for 4 weeks. Patients were randomly assigned to treatment with AML/VAL 5/160âmg FDC (AML/VAL) group or VAL/HCTZ 160/12.5âmg FDC (VAL/HCTZ) group once daily for 8 weeks. A total of 238 patients were enrolled (AML/VAL group, nâ=â121; VAL/HCTZ group, nâ=â117), of whom 228 completed the study. RESULTS: At 8 weeks after randomization, msDBP was significantly decreased in both groups (-9.44â±â0.69âmmâHg in the AML/VAL group and -7.47â±â0.71âmmâHg in the VAL/HCTZ group, both Pâ<â.001 vs baseline). Between group difference was -1.96â±â1.00âmmâHg, indicating that AML/VAL 5/160âmg FDC was not inferior to VAL/HCTZ 160/12.5âmg FDC at primary efficacy endpoint. Control rate of BP defined as the percentage of patients achieving mean sitting SBP (msSBP) <140âmmâHg or msDBP <90âmmâHg (target BP) from baseline to week 8 was significantly higher in the AML/VAL group than that in the VAL/HCTZ group (84.3% [nâ=â102] in the AML/VAL group vs 71.3% [nâ=â82] in the VAL/HCTZ group, Pâ=â.016). At 8 weeks after randomization, mean uric acid level was significantly increased in the VAL/HCTZ group compared to that at baseline (0.64â±â0.08âmg/dL; Pâ<â.001). However, it was slightly decreased from baseline in the AML/VAL group (-0.12â±â0.08âmg/dL; Pâ=â.085). The intergroup difference was significant (Pâ<â.001). CONCLUSION: The effectiveness and safety AML/VAL 5/160âmg FDC are noninferior to those of VAL/HCTZ 160/12.5âmg FDC in patients with hypertension inadequately controlled by valsartan 160âmg monotherapy.

The purpose of this study was to investigate the effects of mixed fruit and vegetable juice on alcohol hangover in healthy adults in a randomized crossover trial. Angelica keiskei/green grape/pear juice (AGP juice) was a mixture of A. keiskei juice, green grape juice, and pear juice at 1:1:1 ratio. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activities of AGP juice were measured in vitro. Fifteen healthy adults consumed alcohol (1.25 g/kg weight), and either water (control group) or AGP juice (AGP juice group). Blood was collected and expiratory-air alcohol levels were measured at 0~360 min after drinking the alcohol. Compared with control, AGP juice had higher ADH and ALDH activity in vitro. The peak alcohol levels in expiratory-air and plasma after drinking AGP juice were significantly lower than those after drinking water. The area under the curves for expiratory-air and plasma alcohol of the AGP juice group were lower than those of the control group. Thirst and headache scores after intake of alcohol were significantly reduced by AGP juice consumption compared with the control group. These data demonstrated that AGP juice could contribute to eliminate alcohol toxicity and hangover symptoms by enhancing alcohol metabolizing enzyme activities.
RESUMEN
OBJECTIVES: Cerebral white matter lesions (WMLs) are regarded to be subclinical ischemic changes of the cerebral parenchyma. Many previous studies have shown that baseline blood pressure (BP) is one of the most important factors for WMLs, but the relation between exercise BP and WMLs has not been fully evaluated. So, we sought to investigate the relationships between cerebral WMLs and peak exercise BP. METHODS: Brain magnetic resonance imaging scan and treadmill testing were performed simultaneously in 130 consecutive subjects without history of stroke or transient ischemic stroke. RESULTS: Among 130 subjects, 42 individuals (32%) presented WMLs. Individuals with WMLs were older than those without WMLs, and baseline systolic BP and pulse pressure were higher in subjects with WMLs. During treadmill test, peak exercise systolic BP was more significantly elevated in subjects with WMLs. In multivariable logistic regression analysis, elevated baseline systolic BP, not peak exercise systolic BP, was associated with the presence of WMLs, independently of age. However, in multivariable logistic regression analysis of 88 normotensive subjects, elevated peak systolic BP during exercise was the only determinant for the presence of WMLs. CONCLUSIONS: Elevated peak systolic BP during exercise is significantly related with WMLs, subclinical small vessel disease of brain, especially in normotensive subjects.

PURPOSE: The purpose of this study was to examine the efficacy and safety of adding ω-3 fatty acids to rosuvastatin in patients with residual hypertriglyceridemia despite statin treatment. METHODS: This study was a multicenter, randomized, double-blind, placebo-controlled study. After a 4-week run-in period of rosuvastatin treatment, the patients who had residual hypertriglyceridemia were randomized to receive rosuvastatin 20 mg/d plus ω-3 fatty acids 4 g/d (ROSUMEGA group) or rosuvastatin 20 mg/d (rosuvastatin group) with a 1:1 ratio and were prescribed each medication for 8 weeks. FINDINGS: A total of 201 patients were analyzed (mean [SD] age, 58.1 [10.7] years; 62.7% male). After 8 weeks of treatment, the percentage change from baseline in triglycerides (TGs) and non-HDL-C was significantly greater in the ROSUMEGA group than in the rosuvastatin group (TGs: -26.3% vs -11.4%, P < 0.001; non-HDL-C: -10.7% vs -2.2%, P = 0.001). In the linear regression analysis, the lipid-lowering effect of ω-3 fatty acids was greater when baseline TG or non-HDL-C levels were high and body mass index was low. The incidence of adverse events was not significantly different between the 2 groups. IMPLICATIONS: In patients with residual hypertriglyceridemia despite statin treatment, a combination of ω-3 fatty acids and rosuvastatin produced a greater reduction of TGs and non-HDL-C than rosuvastatin alone. Further study is needed to determine whether the advantages of this lipid profile of ω-3 fatty acids actually leads to the prevention of cardiovascular event.

PURPOSE: To see the gross tumor volume (GTV) dependency according to the phase selection and reconstruction methods, we measured and analyzed the changes of tumor volume and motion at each phase in 20 cases with lung cancer patients who underwent image-guided radiotherapy. MATERIALS AND METHODS: We retrospectively analyzed four-dimensional computed tomography (4D-CT) images in 20 cases of 19 patients who underwent image-guided radiotherapy. The 4D-CT images were reconstructed by the maximum intensity projection (MIP) and the minimum intensity projection (Min-IP) method after sorting phase as 40%-60%, 30%-70%, and 0%-90%. We analyzed the relationship between the range of motion and the change of GTV according to the reconstruction method. RESULTS: The motion ranges of GTVs are statistically significant only for the tumor motion in craniocaudal direction. The discrepancies of GTV volume and motion between MIP and Min-IP increased rapidly as the wider ranges of duty cycles are selected. CONCLUSION: As narrow as possible duty cycle such as 40%-60% and MIP reconstruction was suitable for lung cancer if the respiration was stable. Selecting the reconstruction methods and duty cycle is important for small size and for large motion range tumors.

BACKGROUND: There are no previous data on serial changes in neutrophil gelatinase-associated lipocalin (NGAL) levels in ST-segment elevation myocardial infarction (STEMI) patients before and after a primary percutaneous coronary intervention (pPCI). The aim of the present study was to evaluate the prognostic value of serial NGAL measurements in patients with STEMI treated by pPCI. MATERIALS AND METHODS: We identified 169 STEMI patients who underwent pPCI within 12 h of symptom onset and had plasma NGAL measurements before (pre-NGAL) and 6 h after (post-NGAL) pPCI. The primary endpoint was 30-day all-cause mortality, including cardiac death, whereas the secondary endpoint was the change in NGAL levels from before to after pPCI. RESULTS: The mean pre-NGAL and post-NGAL levels were 109.2±76.1 and 93.3±83.8 ng/ml, respectively. Thirty-day mortality occurred in 12 (7.1%) patients. In terms of changes in serial NGAL levels, post-NGAL levels were decreased in 132 (79%) patients. Patients with elevated post-NGAL levels showed increased mortality compared with patients with decreased post-NGAL levels (P=0.005). Multivariate analyses indicated that old age and high post-NGAL levels were independent risk factors for 30-day mortality. CONCLUSION: In a large percentage of STEMI patients, plasma post-pPCI NGAL levels were decreased compared with pre-pPCI NGAL levels, even with the administration of potentially nephrotoxic contrast medium. Post-NGAL levels seemed to be superior to pre-NGAL levels for the prediction of 30-day mortality outcome.

Nanofluids comprising nanoparticle suspensions in liquids have significant industrial applications. Prior work performed in our laboratory on the spreading of a nanofluid on a solid substrate has revealed that the structural disjoining pressure gradient caused by the layering of the nanoparticles normal to the confining plane of the film with the wedge profile is a new mechanism for oily soil detachment from the solid substrate. In the present work, we explore the application of this new mechanism for the solid particle detachment using latex particles on glass and a copper-coated wafer substrate using nanofluids. In the experiment, we employed the nanofluids to observe the detachment of the latex particles adhered to the glass substrate. We found that the structural disjoining pressure exerted by the nanoparticles can detach the solid particles on the glass substrate. A video depicting this mechanism is provided. Our results showed that the detachment of the particulate solid particles on the solid substrate was clearly enhanced by the nanofluids, compared to using only pure liquids (such as water). The detachment efficiency was increased with the increase in the nanoparticle volume fraction. Our nanofluids also showed a greater detachment efficiency for the particulate soil removal from the copper-coated wafer substrates compared to that of pure liquids. We found that the detachment efficiency is well correlated with the calculated structural disjoining energy. Our findings in this paper provide new insights for the novel application of the structural disjoining energy mechanism for cleaning hard surfaces.
RESUMEN
RATIONALE: An intracardiac cystic mass is a rare type of mass found in the left atrium. The differential diagnosis of an intracardiac cystic mass includes hydatid cysts, bronchogenic cysts, intracardiac varices, and hemorrhages in some tumor types, including myxoma. PATIENT CONCERNS: We present the case of a 68-year-old woman who presented with episodic dyspnea. DIAGNOSES-INTERVENTIONS-OUTCOMES: Transthoracic echocardiography (TTE) revealed the presence of a left atrial mass mimicking myxoma. However, in postoperative findings, it was determined that the mass was actually a hemorrhagic cyst. Eighteen months later, the patient presented with recurrent exertional dyspnea and TTE revealed the recurrence of a left atrial mass. Computed tomography showed that the mass extended into the right atrium, inferior vena cava, and coronary sinus. After re-operation, the final histological diagnosis was determined to be an undifferentiated pleomorphic sarcoma in the left atrium. LESSONS: An intracardiac hemorrhagic cyst was suspected during the operation of a benign-looking LA mass. As such, we recommend that other rare etiologies be considered and more biopsies be performed when possible.

Small noncoding microRNAs (miRNAs) are not only important for heart and vascular development but are also important in cardiovascular pathophysiology and diseases, such as ischemia and atherosclerosisrelated diseases. However, the effect of miR146a, miR149, miR196a2 and miR499 polymorphisms on coronary artery disease (CAD) susceptibility remain unknown. The aim of the present study was to examine the genotype frequencies of miR146a, miR149, miR196a2 and miR499 polymorphisms in patients with CAD, and assess their clinical applications for diagnosing and monitoring CAD. Using polymerase chain reactionamplified DNA, microRNA polymorphisms were analyzed in 522 patients with CAD and 535 control subjects. The miR149 rs2292832 C>T and miR196a2 rs11614913 T>C polymorphisms were shown to be significantly associated with CAD prevalence. In subgroup analyses according to disease severity, the miR146a rs2910164GG genotype was significantly associated with CAD risk in the stent ≥2 group. In addition, miR146aG/149T/196a2C/499 G allele combination was significantly associated with CAD prevalence (GTCG and GCCG of miR146a/149/196a2/499). The combination genotypes of miR146aGG/149TC+CC and miR149CC/196a2TC were significantly associated with CAD incidence. In subgroup analyses, miR146a rs2910164 C>G increased the risk of developing CAD in nonsmoking, hypertensive and nondiabetic subgroups. Furthermore, miR149 rs2292832 C>T and miR196a2 rs11614913 T>C was shown to increase CAD risk in females and patients aged >63 years old. The miR149T allele, miR196a2C allele and miR146aG/149T/196a2C/499 G allele combination were associated with CAD pathogenesis. The combined effects of environmental factor and genotype combination of miRNA polymorphisms may contribute to CAD prevalence.
