Sarcopenia prevalence and its clinical impact are reportedly variable in chronic obstructive pulmonary disease (COPD) due partly to definition criteria. This review aimed to identify the criteria used to diagnose sarcopenia and the prevalence and impact of sarcopenia on health outcomes in people with COPD. This review was registered in PROSPERO (CRD42018092576). Five electronic databases were searched to August 2018 to identify studies related to sarcopenia and COPD. Study quality was assessed using validated instruments matched to study designs. Sarcopenia prevalence was determined using authors' definitions. Comparisons were made between people who did and did not have sarcopenia for pulmonary function, exercise capacity, quality of life, muscle strength, gait speed, physical activity levels, inflammation/oxidative stress, and mortality. Twenty-three studies (70% cross-sectional) from Europe (10), Asia (9), and North and South America (4) involving 9637 participants aged ≥40 years were included (69.5% men).ive stress biomarkers. Incident mortality was unreported in the literature. Sarcopenia is prevalent in a significant proportion of people with COPD and negatively impacts upon important clinical outcomes. Opportunities exist to optimize its early detection and management and to evaluate its impact on mortality in this patient group.
The aim of this study was to evaluate whether machine learning (ML) can be used to distinguish patients with methamphetamine dependence from healthy controls by using their surface electroencephalography (EEG) and galvanic skin response (GSR) in a drug-simulated virtual reality (VR) environment.

A total of 333 participants with methamphetamine (METH) dependence and 332 healthy control subjects were recruited between January 2018 and January 2019. EEG (five electrodes) and GSR signals were collected under four VR environments one neutral scenario and three METH-simulated scenarios. Three ML classification techniques were evaluated random forest (RF), support vector machine (SVM), and logistic regression (LR).

The MANOVA showed no interaction effects among the two subject groups and the 4 VR scenarios. Taking patient groups as the main effect, the METH user group had significantly lower GSR, lower EEG power in delta (p<.001), and alpha bands (p<.001) than healthy subjects. The EEG power of beta band (p<.001) and gamma band (p<.001) was significantly higher in METH group than the control group. Taking selleck kinase inhibitor (Neutral versus METH-VR) as the main effects, the GSR, EEG power in delta, theta, and alpha bands in neutral scenario were significantly higher than in the METH-VR scenario (p<.001). The LR algorithm showed the highest specificity and sensitivity in distinguishing methamphetamine-dependent patients from healthy controls.

The study shows the potential of using machine learning to distinguish methamphetamine-dependent patients from healthy subjects by using EEG and GSR data. #link# The LR algorithm shows the best performance comparing with SVM and RF algorithm.

In our study, we evaluated the prevalence of CYP2C19, ABCB1 and PON1 single nucleotide polymorphisms (SNP) in patients with coronary atherosclerotic heart disease (CHD) of Chinese Han, Hui, Uygur and Kazak ethnic groups. Five SNPs were detected [CYP2C19 ∗2 (rs4244285), CYP2C19 ∗3 (rs4986893), CYP2C19 ∗17 (rs12248560), ABCB1 (rs1045642) and PON1 (rs662)]. The analysis was performed in 1,337 patients with CHD, including 831 Han, 85 Hui, 352 Uygur and 69 Kazak. The results revealed the differential distribution of the five SNPs. Frequencies of CYP2C19 no function variants in Uygur and Kazak were lower than those in Han and Hui groups (P less then .05). CYP2C19 variants with increased function were more common in Uygur (13.6%) and Kazak (10.9%) groups (P less then .05). Compared with Han and Hui groups, distribution of ABCB1 allele T was more prevalent in Uygur and Kazak groups (53.8% and 50.7%, respectively, P less then .05). PON1 allele A frequencies of 55.7% and 58.7% in Uygur and Kazak showed higher prevalence than in the Han (38.4%) and Hui (43.5%) groups (P less then .05). In conclusion, CYP2C19 *2 and *3 alleles are prevalent in Chinese Han and Hui groups, whereas CYP2C19 *17, ABCB1 T and PON1 A variants are relatively frequent in Chinese Uygur and Kazak ethnic groups. Our findings may provide a theoretical basis for the explanation of ethnic differences in determining clinical therapy strategies and predicting adverse effects.
Pediatric nasopharyngeal carcinoma (NPC) is a rare epithelial origin tumor associated with undifferentiated histology, Epstein-Barr virus (EBV) infection, and genetic risk factors. Childhood NPC is usually clinically silent, often presenting with advanced locoregional compromise, including skull base invasion and cervical lymphadenopathy, and has a better prognosis than adult NPC. This article describes computed tomography (CT) and magnetic resonance imaging (MRI) features in a cohort of 28 pediatric NPC patients.

A retrospective review was performed among children with histopathology proven NPC diagnoses between 1996 and 2019 for this study. The electronic medical records were reviewed to determine demographics, EBV serology, and World Health Organization (WHO) type. Nasopharyngeal CT and/or MRI at presentation for tumor spread as well as density and/or intensity, lymphadenopathy, postcontrast enhancement and diffusion characteristics before treatment were evaluated.

Twenty-eight patients (21 males, 7 females) were included. The mean patient age at diagnosis was 13.3 (range 7 to 17) years. EBV was positive in 71.4% of patients. The majority of patients (78.6%) had a WHO type III tumor, unilateral fossa of Rosenmuller involvement (71.4%). Neuroimaging features were CT isodensity, T1-isointensity, T2-hyperintensity, and heterogeneous postcontrast enhancement for all patients (100%) and restricted diffusion (90%).

Although uncommon in pediatric patients, NPC should be in the differential diagnosis of adolescents presenting with a nasopharyngeal mass. Recognizing key imaging characteristics is helpful in the diagnosis of NPC.
