Atrial fibrillation (AF) and ventricular arrhythmia at the time of ACS diagnosis are known indicators of a poor acute prognosis. However, there is a lack of data regarding the long-term arrhythmic impact of ventricular tachyarrhythmia (VA) on mortality in ACS patients. This study sought to elucidate the impact of tachyarrhythmia on mortality during long-term follow-up in patients with a history of ACS. This retrospective study was conducted in a single university hospital, and it evaluated the clinical outcomes, especially regarding cardiovascular mortality and readmission. The enrolled patients underwent percutaneous coronary intervention (PCI) for ACS between February 2004 and March 2018. Clinical information was attained by a thorough chart review. We retrospectively analyzed 560 ACS patients. We reviewed all electrocardiograms (ECGs) before and immediately after PCI, during hospitalization, and within 3 months of the index PCI. Three months after the index PCI procedure, any Holter monitoring or ECG was also reviewed for arrhythmia diagnosis. During follow-up, 91 patients were diagnosed with AF and 36 patients were diagnosed with VA. Overall mortality was related to the presence of anemia, low body mass index, low left ventricular ejection fraction after PCI, late-diagnosed AF, and any VA during follow-up. Readmission was higher in patients with chronic kidney disease and newly diagnosed AF during the follow-up. Diagnosis of late tachyarrhythmia during follow-up was associated with increased mortality in post-ACS patients.The aim of the present study was to investigate the effect of teriparatide on device-related vertebral osteopenia after single lumbar spinal interbody fusion and compare osteopenia in fused and nonfused spinal segments using Hounsfield unit (HU) values. The present study was a retrospective cohort study. We reviewed 68 consecutive patients (28 men and 40 women) who underwent single-segment (L4-5) transforaminal lumbar interbody fusion with cage and pedicle screw fixation. The patients were divided into 2 groups according to whether they were treated with teriparatide (teriparatide and nonmedication groups). The primary outcome measure was HU values measured on computed tomography images from each L1 to S1 vertebral body12-month postoperatively. Secondary outcome measures were femoral neck bone mineral density (BMD), T-score, osseous union, and clinical outcomes using the Japanese Orthopedic Association scoring system 12-month postoperatively. There were significant decreases in HU values of lumbar vertebral bodies at all levels and BMD and T-score values obtained using dual-energy X-ray absorptiometry of the femur between preoperative and postoperative 12-month computed tomography in the nonmedication group (P less then .05). On the other hand, there were no significant differences between properative and postoperative 12-month HU values of each lumbar vertebral body and BMD values of the femur in the teriparatide group. Osseous fusion scores in the teriparatide group were significantly better than those in the nonmedication group. There were no significant differences in postoperative Japanese Orthopedic Association scores between the 2 groups. Administration of teriparatide during the perioperative period may prevent bone loss associated with spinal fusion surgery.
This study aimed to investigate the relationship between cervical region subcutaneous fat tissue thickness and the presence and level of cervical intervertebral disc degeneration (IVDD).
Magnetic resonance imaging examinations of patients referred to our clinic for the investigation of neck pain were evaluated retrospectively. A total of 300 women aged 30-40 years were included in the study. The presence and level of IVDD were evaluated for each patient. YK-4-279 purchase The cervical subcutaneous fat tissue thickness was also measured.
IVDD was determined as Grade 1 for 88 patients (29.3%), Grade 2 for 56 patients (18.6%), Grade 3 for 82 patients (27.3%), Grade 4 for 60 patients (20%), and Grade 5 for 14 patients (4.6%). Subcutaneous fat tissue thickness was higher in patients with cervical disc degeneration (mean 6.28 ± 0.19 mm) than in those without cervical disc degeneration (mean 5.33 ± 0.18 mm) (P = .001). There was a positive correlation between the degree of cervical disc degeneration and subcutaneous fat tissue thickness ( = 0.001, r = 0.245).
An increase in the cervical fat tissue thickness is a predisposing factor for the development of degeneration of the intervertebral disc. There is a close relationship between subcutaneous fat tissue thickness and the degree of degeneration.

Clinical data of 3867 AMI patients hospitalized from November 2010 to October 2019 in the Border Yanbian Minority Autonomous Prefecture, China were collected, and 3158 patients with definite AMI onset times were analyzed. The clinical data analyzed included the time of onset, nationality, age, laboratory data. We divided the patients into 4 groups based on the timepoint of their AMI onsets 0000-0559, 0600-1159, 1200-1759, and 1800-2359. We also divided the patients based on nationality Chinese Korean and Han groups. We observed that there is a circadian rhythm in the incidence of AMI, and the peak of AMI is in the morning (700-900). Unexpectedly, the incidence of AMI was significantly lower in the cold winter than that of other 3 warm seasons (P less then 0.01) and the peak of AMI presented at the months of the large contrast between day and night temperature difference (over 20°C) like May of Spring and October of Fall. Finally, there was no difference in circadian rhythm between Chinese Korean and Han, although these groups differed in age, body mass index, and the inflammatory cell level. These findings have shown a different seasonal and circadian variation in onset of AMI. Further studies are required to determine the pathophysiological mechanism(s) underlying these differences and to guide prevention of AMI for reducing its mortality and disability.
Chemotherapeutic agents have been associated with cardiotoxicity; thus, they require close monitoring. Several echocardiographic variables have been investigated as early predictors of symptomatic cardiotoxicity in patients undergoing chemotherapy.
To identify if global longitudinal strain (GLS) is a better predictor of symptomatic cardiotoxicity compared to left ventricular ejection fraction (LVEF) in patients receiving chemotherapy.
MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials were searched from inception through December 2020. Adults who developed symptomatic cardiotoxicity (New York Heart Association [NYHA] Class III-IV heart failure, cardiac arrest, or cardiac death) after undergoing chemotherapy with pre- and postchemotherapy echocardiographic measures of cardiac function were included. The primary focus was on the prediction of symptomatic cardiotoxicity. Estimates were reported as random effects hazard ratios (HR) with 95% confidence intervals (CI).
Four studies met incldomized trial included in this meta-analysis. The data for baseline GLS as a predictor of symptomatic cardiotoxicity is encouraging, but definite evidence that GLS may be superior to LVEF is lacking. Prospective randomized, blinded trials are required to identify if 1 echocardiographic parameter may be superior to the other.
GLS may predict symptomatic cardiotoxicity and be used to monitor patients on chemotherapy for symptomatic cardiac dysfunction. While the pooled results for baseline LVEF identified that it is not a predictor of symptomatic cardiotoxicity, this differs from the findings of the only randomized trial included in this meta-analysis. The data for baseline GLS as a predictor of symptomatic cardiotoxicity is encouraging, but definite evidence that GLS may be superior to LVEF is lacking. Prospective randomized, blinded trials are required to identify if 1 echocardiographic parameter may be superior to the other.The Sequential Organ Failure Assessment (SOFA) could function as an effective risk stratification tool in the admission of critically ill patients with COVID-19 and would allow stratification based on a risk assessment. We aimed to examine whether the SOFA score is useful to define 2 severity profiles in COVID-19 patients admitted to ICU mild with SOFA less then 5, and severe with SOFA ≥ 5. A retrospective cohort, multicenter study was conducted from February 11 to May 11, 2020. We analyzed patients admitted to all ICUs of the 14 public hospitals of the Castilla-La Mancha Health Service at the beginning of the pandemic and with SARS-CoV-2 infection. Patients were divided in 2 groups according to the level of severity by SOFA at admission to the ICU. Cox regression was used to evaluate factors associated with survival and Kaplan-Meier test to examine survival probability. In total, 405 patients with a complete SOFA panel were recruited in the 14 participating ICUs. SOFA less then 5 group showed that age above 60 years and D-dimer above 1000 ng/mL were risk factors associated with lower survival. In SOFA ≥ 5 it was found that high blood pressure was a risk factor associated with shorter survival. Kaplan-Meier showed lower survival in SOFA ≥ 5 in combination with high blood pressure, time since viral symptom onset to admission in ICU less then 7 days, D-dimer ≥1000 ng/mL and respiratory pathology. However, SOFA less then 5 showed only higher age (≥60 years) associated with lower survival. Age over 60 years and D-dimer over 1000 ng/mL were risk factors reflecting lower survival in patients with SOFA less then 5. Moreover, SOFA ≥ 5 patients within a week after COVID-19 onset and comorbidities such as high blood pressure and previous respiratory pathology showed lower survival.
Adjuvant chemotherapy is still the standard treatment for stage III-N2 nonsmall cell lung cancer after R0 resection, and it is still controversial whether conventional adjuvant radiotherapy is needed. We used meta-analysis to try to answer whether adjuvant postoperative chemoradiotherapy (POCRT) can bring survival benefits to patients with stage III-N2 nonsmall cell lung cancer after R0 resection.
Up to June 25, 2021, the databases of PubMed, Embase, Cochrane Library, CNKI, and Wanfang were searched, and clinical studies on POCRT for stage III-N2 nonsmall cell lung cancer were included. RevMan5.4 software was used for meta-analysis.
A total of 8959 patients were included in 5 randomized controlled trials and 17 retrospective studies. The results of the meta-analysis showed that POCRT could improve 3 and 5 years overall survival (OS) rate (OR = 1.52, 95%CI 1.05-2.20; OR = 1.30, 95%CI 1.16-1.46), 3 and 5 years disease-free survival (DFS) rate (OR = 1.34, 95%CI 1.01-1.76; OR = 1.74, 95%CI 1.43-2.12), and 5-year locoregional recurrence-free survival (LRFS) rate (OR = 2.
