Abstract
Idiopathic dilated cardiomyopathy (IDC) has been hypothesized as a multifactorial disorder initiated by an environment trigger in individuals with predisposing human leukocyte antigen (HLA) alleles. Published data on the association between HLA-DR3 antigen and IDC risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Studies were identified by searching the PUBMED and Embase database (starting from June 2015). A total of 19 case-control studies including 1378 cases and 10383 controls provided data on the association between HLA-DR3 antigen and genetic susceptibility to IDC. Overall, significantly decreased frequency of HLA-DR3 allele (OR=0.72; 95%CI=0.58-0.90; P=0.004) was found in patients with IDC compared with controls. When stratified by myocardial biopsy or non-biopsy cases, statistically decreased risk was found for IDC in myocardial biopsy cases (OR=0.69; 95%CI=0.57-0.84; P=0.0003). In the subgroup analysis by ethnicity, borderline statistically significantly decreased risk was found among Europeans from 12 case-control studies (OR=0.76; 95%CI=0.58-1.00; P=0.05). In conclusion, our results suggest that individuals with HLA-DR3 antigen may have a protective effect against IDC.

Braz J Med Biol Res 2016; 49:S0100-879X2016000300707. [PMID: 26840711 PMCID: PMC4763825 DOI: 10.1590/1414-431x20155127] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2015] [Accepted: 11/05/2015] [Indexed: 01/20/2023] Open
Abstract
Contact force (CF) sensing technology allows real-time monitoring during catheter
ablation for atrial fibrillation (AF). However, the effect of CF sensing technology
on procedural parameters and clinical outcomes still needs clarification. Because of
the inconsistent results thus far in this area, we performed a meta-analysis to
determine whether CF sensing technology can improve procedural parameters and
clinical outcomes for the treatment of AF. Studies examining the benefits of CF
sensing technology were identified in English-language articles by searching the
MEDLINE, Web of Science, and Cochrane Library databases (inception to May 2015). Ten
randomized, controlled trials involving 1834 patients (1263 males, 571 females) were
included in the meta-analysis (681 in the CF group, 1153 in the control group).
Overall, the ablation time was significantly decreased by 7.34 min (95%CI=-12.21 to
-2.46; P=0.003, Z test) in the CF group compared with the control group. CF sensing
technology was associated with significantly improved freedom from AF after 12 months
(OR=1.55, 95%CI=1.20 to 1.99; P=0.0007) and complications were significantly lower in
the CF group than in the control group (OR=0.50, 95%CI=0.29 to 0.87; P=0.01).
However, fluoroscopy time analysis showed no significantly decreased trend associated
with CF-guided catheter ablation (weighted mean difference: -2.59; 95%CI=-9.06 to
3.88; P=0.43). The present meta-analysis shows improvement in ablation time and
freedom from AF after 12 months in AF patients treated with CF-guided catheter
ablation. However, CF-guided catheter ablation does not decrease fluoroscopy
time.

Abstract
MicroRNAs (miRNAs) are a class of non-coding endogenous negative regulators that regulate gene expression at both the transcriptional and post-transcriptional levels. However, little is known about the expression characteristics of miRNAs during pollen development in Brassica oleracea. In this study, five known and three novel miRNAs were identified and their expression patterns were compared in the flower buds of B. oleracea using stem-loop reverse transcription polymerase chain reaction (RT-PCR) and quantitative real-time PCR. The results revealed that the eight miRNAs were constantly expressed during pollen development but exhibited different expression patterns during the five developmental stages of the flower buds between the cytoplasmic male sterile (CMS) line and its fertile maintainer. The highest miRNA expression levels occurred at the uninucleate microspore stage in the fertile line Bo01-12B and at the bicellular pollen stage in the CMS line Bo01-12A. Potential target genes for the miRNAs were predicted and analyzed, and suggested that miRNAs are involved in the regulation of target genes related to pollen development. The results of this study further our understanding of the regulatory role of miRNAs in pollen development.

Abstract
Coronary angiography can be a high-risk condition for the incidence of contrast-induced nephropathy (CIN) in elderly patients. Reduced glutathione, under a variety of mechanisms, may prevent CIN in this procedure. We prospectively examined whether hydration with reduced glutathione is superior to hydration alone for prevention of CIN in an elderly Han Chinese population. A total of 505 patients (271 males and 234 females) aged 75 years or older who underwent non-emergency coronary angiography or an intervention were randomly divided into two groups. The treatment group received hydration with reduced glutathione (n=262) and the control group received hydration alone (n=243). Serum creatinine and blood urea nitrogen levels were measured prior to coronary angiography and 48 h after this procedure. The primary endpoint was occurrence of CIN, which was defined as 25% or 44.2 µmol/L above baseline serum creatinine levels 48 h after the procedure. The overall incidence of CIN was 6.49% in the treatment group and 7.41% in the control group, with no significant difference between the groups (P=0.68). In subgroup analysis by percutaneous coronary intervention, no significant differences were found between the two groups. In summary, reduced glutathione added to optimal hydration does not further decrease the risk of CIN in elderly patients undergoing coronary angiography or an intervention.

Abstract
BACKGROUND Whether a combination of chemotherapy and erlotinib is beneficial for advanced non-small cell lung cancer (NSCLC) remains controversial. This study aimed to summarize the currently available evidence and compare the efficacy and safety of chemotherapy plus erlotinib versus chemotherapy alone for treating advanced NSCLC. METHODS EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials were searched for relevant studies. Our protocol was registered in PROSPERO (CRD42014015015). RESULTS Nine randomized controlled trials with a total of 3599 patients were included. Compared to chemotherapy alone, chemotherapy plus erlotinib was superior in PFS (HR = 0.76 [95% CI 0.62, 0.92], P = 0.006), and no statistically significant difference was observed in OS (HR = 0.94 [95% CI 0.86, 1.03], P = 0.16). Intercalated erlotinib plus chemotherapy demonstrated improvements in PFS (HR = 0.67 [95% CI 0.50, 0.91], P = 0.009) and OS (HR = 0.82 [95% CI 0.69, 0.98], P = 0.03). Continuous erlotinib plus chemotherapy treatment failed to demonstrate improvements in PFS (HR = 0.91 [95% CI 0.80, 1.04], P = 0.16) and OS (HR = 0.98 [95% CI 0.89, 1.09], P = 0.75). The association of chemotherapy plus erlotinib with improvement in PFS was significant in never smoking patients (HR = 0.46 [95% CI 0.37, 0.56], P<0.00001) but not in smoking patients (HR = 0.70 [95% CI 0.49, 1.00], P = 0.05). Among patients with EGFR mutant tumors, chemotherapy plus erlotinib demonstrated significant improvements in PFS (HR = 0.31 [95% CI 0.17, 0.58], P = 0.0002) and OS (HR = 0.52 [95% CI 0.30, 0.88], P = 0.01). Among patients with EGFR wild-type tumors, no statistically significant difference was observed with respect to PFS (HR = 0.87 [95% CI 0.70, 1.08], P = 0.21) and OS (HR = 0.78 [95% CI 0.59, 1.01], P = 0.06). CONCLUSION Combination of chemotherapy and erlotinib is a viable treatment option for patients with NSCLC, especially for patients who never smoked and patients with EGFR mutation-positive disease. In addition, intercalated administration is an effective combinatorial strategy.

Abstract
OBJECTIVE This study examined the usefulness of nasal Duo positive airway pressure (DuoPAP) in the treatment of very low birth weight preterm infants with neonatal respiratory distress syndrome (NRDS). PATIENTS AND METHODS Eighty-five very low birth weight preterm infants with NRDS were randomly divided into two groups. Forty-five infants were treated with DuoPAP, while 40 infants were treated using nasal continuous positive airway pressure (nCPAP). The study outcomes were pH, PaCO, PaO₂, oxygenation index (PaO₂/FiO₂), and the number of failure cases at 1, 12, and 24 hours after non-invasive respiratory support. RESULTS At all studied time points, after non-invasive respiratory support, PaCO₂, PaO₂ and oxygenation index were significantly (p < 0.05) better in the nasal DuoPAP group compared with nasal CPAP group. In addition, rates of failure of assisted ventilation (respectively, 4.44% vs. 22.50%) and the occurrence of apnea (13.33% vs. 32.50%) were significantly (p < 0.05) better in the nasal DuoPAP group. Other parameters (such as duration of noninvasive ventilation, number of retinopathies of premature children, intraventricular hemorrhages, or periventricular leukomalacias) were comparable between both non-invasive regimen. CONCLUSIONS Nasal DuoPAP better improves oxygenation, reduces CO₂ retention, and diminishes the need for invasive mechanical ventilation and complications in the treatment of NRDS.

Abstract
OBJECTIVE The aim of this study was to identify the hub genes and dysregulated pathways of hepatocellular carcinoma (HCC) and explore the molecular mechanism of the biological process associated with HCC. MATERIALS AND METHODS Microarray data were got from NCBI Gene Expression Omnibus (GEO) database. The most significant top 100 up-regulated gene signatures and top 100 down-regulated gene signatures were identified by integrated analysis of the multiple microarray datasets using a novel model genome-wide relative significance (GWRS) and genome-wide global significance (GWGS). Gene Ontology (GO) enrichment analysis and pathway analysis of those genes were performed based on Gene Ontology website and Kyoto Encyclopedia of Genes and Genomes (KEGG). Protein-protein interaction (PPI) network was constructed using Cytoscape 2.1. In addition, we analysed the significantly dysregulated signaling pathways across the PPI network and KEGG pathway analysis. RESULTS We screened 2920 up-regulated and 2231 down-regulated gene signatures across multiple studies by GWRS and GWGS. The top 100 up-regulated and top 100 down-regulated gene signatures were selected for further research. GO enrichment analysis showed that these genes significantly enriched in terms of mitosis (p = 5.83×10-20), nuclear division (p = 5.83×10-20) and M phase of mitotic cell cycle (p = 9.39×10-20). The most significant terms of KEGG pathway included cell cycle (p = 1.33×10-8), oocyte meiosis (p = 1.41×10-4), drug metabolism (p = 2.15×10-4) and p53 signaling pathway (p = 3.57×10-4). PPI network suggested that BIRC5, CDC20, CCNB1, BUB1B, MAD2L1 and CDK1 were important significant genes which were considered as hub genes. Across the PPI and pathway, cell cycle, oocyte meiosis and p53 signaling pathway were the significantly dysregulated pathways. CONCLUSIONS Our study displayed robust gene signatures in HCC. It showed that the dysregulations of cell cycle, oocyte meiosis, p53 signaling pathway and progesterone-mediated oocyte maturation pathway were closely associated to the development and progression of HCC. Besides, genes BIRC5, CDC20, CCNB1, BUB1B, MAD2L1 and CDK1 as the hub genes might play important roles for diagnosing and therapy of HCC.

Abstract
To investigate FoxO1 expression in term placenta and omental adipose tissue between pregnant women with gestational diabetes mellitus (GDM) and those with normal glucose tolerance (control). The relationship between FoxO1 and tumor necrosis factor-α (TNF-α) in cultured trophoblast cells was also investigated.Maternal serum, term placenta and omental adipose tissue were collected from the GDM group (n=20) and the control group (n=20). Serum TNF-α, IL-6 and IL-1β concentration was measured. Fasting plasma glucose (FPG) and fasting serum insulin (FIN) were investigated to calculate an insulin resistance index (HOMA-IR). Immunohistochemistry (IHC) was performed to examine the localization of FoxO1 protein in the placenta and adipose tissue. Real time RT-PCR and Western blotting were used to compare the levels of FoxO1 and TNF-α gene and protein between the 2 groups. Trophoblast cells (HTR-8/SVneo and BeWo cells) were cultured to detect the regulation of TNF-α on FoxO1 expression. The effect of FoxO1 knockdown on TNF-α stimulated expression of pro-inflammatory cytokines was also investigated.Compared to control group, Serum TNF-α, IL-6 and IL-1β concentration was higher in GDM group. FoxO1 was expressed in both the placenta and omental adipose tissue. The gene and protein expression of FoxO1 and TNF-α was higher in the GDM group than the control group in both tissues. The expression of FoxO1 in the placenta was positively correlated with HOMA-IR and TNF-α. Stimulation of TNF-α gene increased the expression of FoxO1 in cultured trophoblast cells. FoxO1 deletion in these cells attenuated TNF-α-induced expression of the pro-inflammatory cytokines IL-1β and IL-6.FoxO1 has a potential role as a pro-inflammatory factor in GDM, and may be involved in the development of IR through interaction with TNF-α.

Abstract
Peripheral arterial aneurysms are a feature of Kawasaki disease (KD), and very little information has been published on this feature. Failure to recognize this important complication can lead to severe consequences such as peripheral gangrene. We present the case of a 2-year-old girl, diagnosed with KD at 11 months of age, who developed multiple giant aneurysms in the bilateral axillary arteries and right coronary artery. Imaging findings from dual-source computed tomography are described in this report.

Abstract
Loss of the DNA mismatch repair (MMR) protein MSH3 leads to the development of a variety of tumors in mice without significantly affecting survival rates, suggesting a modulating role for the MutSβ (MSH2-MSH3) complex in late-onset tumorigenesis. To better study the role of MSH3 in tumor progression, we crossed Msh3(-/-) mice onto a tumor predisposing p53-deficient background. Survival of Msh3/p53 mice was not reduced compared with p53 single mutant mice; however, the tumor spectrum changed significantly from lymphoma to sarcoma, indicating MSH3 as a potent modulator of p53-driven tumorigenesis. Interestingly, Msh3(-/-) mouse embryonic fibroblasts displayed increased chromatid breaks and persistence of γH2AX foci following ionizing radiation, indicating a defect in DNA double-strand break repair (DSBR). Msh3/p53 tumors showed increased loss of heterozygosity, elevated genome-wide copy-number variation and a moderate microsatellite instability phenotype compared with Msh2/p53 tumors, revealing that MSH2-MSH3 suppresses tumorigenesis by maintaining chromosomal stability. Our results show that the MSH2-MSH3 complex is important for the suppression of late-onset tumors due to its roles in DNA DSBR as well as in DNA MMR. Further, they demonstrate that MSH2-MSH3 suppresses chromosomal instability and modulates the tumor spectrum in p53-deficient tumorigenesis and possibly has a role in other chromosomally unstable tumors as well.

Abstract
Activating and inhibitory receptors control natural killer (NK) cell activity. T-cell immunoglobulin and ITIM (immunoreceptor tyrosine-based inhibition motif) domain (TIGIT) was recently identified as a new inhibitory receptor on T and NK cells that suppressed their effector functions. TIGIT harbors the immunoreceptor tail tyrosine (ITT)-like and ITIM motifs in its cytoplasmic tail. However, how its ITT-like motif functions in TIGIT-mediated negative signaling is still unclear. Here, we show that TIGIT/PVR (poliovirus receptor) engagement disrupts granule polarization leading to loss of killing activity of NK cells. The ITT-like motif of TIGIT has a major role in its negative signaling. After TIGIT/PVR ligation, the ITT-like motif is phosphorylated at Tyr225 and binds to cytosolic adapter Grb2, which can recruit SHIP1 to prematurely terminate phosphatidylinositol 3-kinase (PI3K) and MAPK signaling, leading to downregulation of NK cell function. In support of this, Tyr225 or Asn227 mutation leads to restoration of TIGIT/PVR-mediated cytotoxicity, and SHIP1 silencing can dramatically abolish TIGIT/PVR-mediated killing inhibition.

Abstract
OBJECTIVE To determine the frequency of and risk factors for major adverse drug reactions (MADRs) associated with anti-tuberculosis treatment at a tuberculosis (TB) referral hospital in the Republic of Korea. METHODS Data from an ongoing natural history cohort study were analyzed for permanent regimen changes due to adverse drug reactions and confirmed by chart review. RESULTS Among 655 subjects, there were 132 MADRs in 112 (17%) subjects. The most common MADRs were gastrointestinal (n = 53), musculoskeletal (n = 22), psychiatric (n = 10), visual (n = 9) and peripheral neuropathic (n = 8). MADRs were more frequent in subjects being treated with second-line regimens (16%) compared to first-line regimens (2.5%). Drugs frequently associated with MADRs were amikacin (3/10, 30%), linezolid (8/29, 28%), para-aminosalicylic acid (47/192, 24%), pyrazinamide (31/528, 5.8%), macrolides (2/44, 4.5%) and cycloserine (12/272, 4.4%). Fluoroquinolones accounted for a single MADR (1/377, 0.003%), despite widespread usage. In multivariate analysis, infection with multi- or extensively drug-resistant disease and previous history of anti-tuberculosis treatment were risk factors for MADR, with adjusted hazard ratios of respectively 2.2 (P = 0.02) and 1.6 (P = 0.04). CONCLUSION MADRs are common during anti-tuberculosis chemotherapy in this population, occurring in more than one in six subjects. New and less toxic agents to treat drug-resistant TB are urgently needed.
