A balanced translocation affecting DISC1 cosegregates with several psychiatric disorders, including schizophrenia, in a Scottish family. DISC1 is a hub protein of a network of protein–protein interactions involved in multiple developmental pathways within the brain. Gene set‐based analysis has been proposed as an alternative to individual analysis of single nucleotide polymorphisms (SNPs) to get information from genome‐wide association studies. In this work, we tested for an overrepresentation of the DISC1 interacting proteins within the top results of our ranked list of genes based on our previous genome‐wide association study of missense SNPs in schizophrenia. Our data set consisted of 5100 common missense SNPs genotyped in 476 schizophrenic patients and 447 control subjects from Galicia, NW Spain. We used a modification of the Gene Set Enrichment Analysis adapted for SNPs, as implemented in the GenGen software. The analysis detected an overrepresentation of the DISC1 interacting proteins (permuted P‐value = 0.0158), indicative of the role of this gene set in schizophrenia risk. We identified seven leading‐edge genes, MACF1, UTRN, DST, DISC1, KIF3A, SYNE1, and AKAP9, responsible for the overrepresentation. These genes are involved in neuronal cytoskeleton organization and intracellular transport through the microtubule cytoskeleton, suggesting that these processes may be impaired in schizophrenia. 相似文献

Although obesity has been associated with imbalances in cardiac autonomic nervous system, it is unclear whether there are differential relationships between adiposity measures and heart rate variability (HRV) measures. We aimed to examine differences in the relationship between adiposity measures and HRV indices in a healthy Korean population.
Materials and Methods
In all, 1409 non-smokers (811 males, 598 females) without known histories of cardiovascular (CV), endocrine, or neurological diseases underwent adiposity measurements [(body mass index (BMI), percentage of body fat mass (PBF), and waist-to-hip ratio (WHR)], the HRV assessment (SDNN, RMSSD, LF, HF, LF/HF, and pNN50), and examination for CV risk factors (fasting glucose, LDL-cholesterol, HDL-cholesterol, triglycerides, hs-CRP, and blood pressure).
Results
Compared with BMI and PBF, WHR was more strongly correlated with each HRV index and more likely to predict decreased HRV (<15 percentile vs. ≥15 percentile of each HRV index) in ROC curves analysis. In linear regression analysis, all adiposity measures were inversely associated with each HRV measure before adjusting for age, gender, and CV risk factors (p<0.05). After adjusting for the covariates, WHR was inversely related to RMSSD, LF, and pNN50; PBF with RMSSD, HF, and pNN50; BMI with RMSSD (p<0.05). The inversed association between HRV indices and the gender-specific WHR tertile was significant for subjects with BMI ≥25 kg/m2, but not for those with BMI <25 kg/m2.
Conclusion
WHR and PBF appear to be better indicators for low HRV than BMI, and the association between abdominal adiposity and HRV may be stronger in overweight subjects. 相似文献
Marek’s disease virus Chinese strain GX0101, isolated in 2001, is the first reported recombinant gallid herpesvirus type 2 (GaHV-2) field strain with one reticuloendotheliosis virus (REV) long terminal repeat (LTR) insert. We constructed an infectious bacterial artificial chromosome (BAC) clone of GX0101, which showed characteristics very similar to those of the parental virus in replication and pathogenicity. Using the GX0101 BAC clone, the complete genome of GX0101 was sequenced and analyzed. The length of the GX0101 genome is 178,101 bp, and it contains only one REV-LTR insert at a site 267 bp upstream of the sorf2 gene. 相似文献
Although glucocorticoids (GCs) are effective in inducing remission in systemic lupus erythematosus (SLE) patients, there is a significant variation in response to therapeutic GCs, and some patients do not achieve full remission. The aim of this study was to explore the impact of environmental factors on the efficacy of GCs in a Chinese population with SLE. This was a prospective cohort study, and a total of 260 SLE patients treated with GCs (prednisone) were followed up for 12 weeks. The efficacy of GCs was measured with the scores on SLE disease activity index. Environmental factors were collected using a questionnaire. Single-variable analysis and multivariate logistic regression analysis were used to discriminate the impact of environmental factors on the efficacy of GCs. Two hundred forty-seven patients (95.00 %) completed the 12-week follow-up. Among these patients, 131 (53.04 %) were classified into sensitive group and 116 (46.96 %) were classified into insensitive group. Results from logistic analysis showed that the following environmental factors were significantly associated with decreased efficacy of GCs: high salt intake (OR?=?3.464, 95%CI?=?1.481–8.102, P?=?0.004), introverted personality (OR?=?3.550, 95%CI?=?1.901–6.628, P?<?0.0001), experience with negative life events (OR?=?5.526, 95%CI?=?1.612–18.946, P?=?0.007), and history of allergy (OR?=?2.966, 95%CI?=?1.312–6.704, P?=?0.009). These results indicate that environmental factors, including salt intake, personality, experience with negative life events, and history of allergy, may play an important role in the efficacy of GCs in the Chinese population with SLE. 相似文献
Suicide is a leading cause of death in patients with schizophrenia. This nationwide cohort study investigated the incidence of each suicide method in patients with schizophrenia compared with the general population.
Methods
In total, records of 174,039 patients with schizophrenia were obtained from the National Health Insurance Research Database in Taiwan from 2001 to 2016. This schizophrenia cohort was linked with the national mortality database, and 26,926 patients died during this follow-up period. Of the deceased, 3033 had died by suicide. Univariate Cox regression was used to estimate the demographic variables associated with suicide. We estimated the difference in the proportion of each suicide method used in patients with schizophrenia compared with the general population. The incidence and standardized mortality ratio (SMR) of each suicide method were calculated and stratified based on sex.
Results
Patients aged 25–34 years exhibited the highest suicide risk. Compared with the general population, patients with schizophrenia were more likely to commit suicide by jumping and drowning and less likely to use charcoal-burning and hanging. Women showed a higher incidence of suicide by drowning and jumping than did men. Comorbidity with substance use disorders (SUDs) was associated with a high suicide SMR (26.9, 95% confidence interval [CI] = 23.4–28.9), particularly for suicide by jumping (61.2, 95% CI = 48.3–76.3).
Conclusions
Patients with schizophrenia had higher suicide rates for all methods than did the general population. Suicide method differed based on sex. Patients with SUDs exhibit a high SMR for each suicide method and warrant intensive clinical attention.
To examine the multidimensional concept of patient-health care provider (HCP) communication, its effects on patient satisfaction with oncology care services, and related racial differences.
Methods
The current analysis draws from a population-based survey sample of 1011 African American and 1034 Caucasian American men with newly diagnosed prostate cancer. The variables of satisfaction with health care services, interpersonal treatment, contextual knowledge of the patient, and prostate cancer communication were analyzed using multiple-group structural equation modeling.
Results
Regardless of race, patient-HCP communication was related positively to interpersonal treatment by the HCP, HCP's contextual knowledge of the patient, and prostate cancer communication. More positive patient-HCP communication was related to more satisfaction with health care services. Racial differences were significant in the relationships between patient-HCP communication and prostate cancer communication.
Conclusion
Content and interpersonal relationships are important aspects of patient-HCP communication and affect patient satisfaction with oncologic care for prostate cancer.
Practice implications
HCPs need to integrate the transfer of information with emotional support and interpersonal connection when they communicate with men with newly diagnosed prostate cancer. 相似文献
A H3N2 canine influenza virus, A/canine/Guangdong/3/2011 (H3N2), was isolated from roaming dogs in rural China. Sequence and phylogenetic analysis of eight gene segments revealed that the A/canine/Guangdong/3/2011 (H3N2) was most similar to a recent H3N2 canine influenza virus isolated in cats from South Korea, which originated from an avian strain. To our knowledge, this is the first report of an avian-origin H3N2 CIV which was isolated from roaming dogs in China. The epidemiologic information provided herein suggests that continued study is required to determine if this virus could be established in the roaming dog population in rural China and pose potential threats to public health. 相似文献
