Age differences in everyday stressor-related negative affect: A coordinated analysis.

Psychol Aging 2018 Dec 13. Epub 2018 Dec 13.

Department of Biobehavioral Health and Medicine.

Advancing age is often characterized by preserved or even enhanced emotion regulation, which is thought to manifest in terms of age-related reductions in the within-person association between stressors and negative affect. Existing research from ecological momentary assessment and end-of-day daily diary studies examining such age-related benefits have yielded mixed results, potentially due to differences in samples, design, and measurement of everyday stressors and negative affect. We conducted a coordinated analysis of 5 ecological momentary assessments and 2 end-of-day daily diary studies to examine adult age differences in the within-person association between everyday stressors and negative affect.

p27 - p(RhoB)lematic in lung cancer.

J Pathol 2018 Dec 14. Epub 2018 Dec 14.

Division of Medical Biochemistry, Biocenter, Innsbruck Medical University, Innsbruck, Austria.

Lung cancer is the leading cause of cancer mortality worldwide, with adenocarcinomas of the non-small cell lung carcinoma (NSCLC) subtype accounting for the majority of cases. Therefore, an urgent need exists for a more detailed dissection of the molecular events driving NSCLC development and the identification of clinically relevant biomarkers. Even though originally identified as a tumour suppressor, recent studies associate the cytoplasmically (mis)localised CDK inhibitor p27 (p27) with unfavourable responses to chemotherapy and poor outcomes in NSCLC, supporting the hypothesis that the protein can execute oncogenic activities.

Insights into the Pulmonary Vascular complications of heart failure with Preserved Ejection Fraction.

J Physiol 2018 Dec 13. Epub 2018 Dec 13.

Pittsburgh Heart, Lung, Blood and Vascular Medicine Institute, University of Pittsburgh, Pittsburgh, PA, USA.

Pulmonary hypertension in the setting of heart failure with preserved ejection fraction (PH-HFpEF) is a growing public health problem that is increasing in prevalence. While PH-HFpEF is defined by a high mean pulmonary artery pressure, high left ventricular end-diastolic pressure and a normal ejection fraction, some HFpEF patients develop PH in the presence of pulmonary vascular remodeling with a high transpulmonary pressure gradient or pulmonary vascular resistance. Aging, increased left atrial pressure and stiffness, mitral regurgitation, as well as features of metabolic syndrome, which include obesity, diabetes, and hypertension, are recognized as risk factors for PH-HFpEF.

Recipient working status is independently associated with outcomes in heart and lung transplantation.

Clin Transplant 2018 Dec 13:e13462. Epub 2018 Dec 13.

Division of Cardiac Surgery, University of California, Los Angeles, Los Angeles, CA, USA, 90095.

Employment status may capture elements of patients' physical strength, mental resilience, and socioeconomic status to better prognosticate transplant outcomes. This study characterized the effect of working status on thoracic transplant outcomes by evaluating the United Network for Organ Sharing registry for adult lung or heart transplants from 2005 to 2016. Kaplan-Meier estimates illustrated 5-year and 10-year survival by working status at transplant, while multivariable Cox proportional hazards regressions controlled for baseline differences, including functional and socioeconomic status.

Long noncoding RNA CCAT2 functions as a competitive endogenous RNA to regulate FOXC1 expression by sponging miR-23b-5p in lung adenocarcinoma.

J Cell Biochem 2018 Dec 12. Epub 2018 Dec 12.

Department of Thoracic Surgery, Huai'an Second People's Hospital and The Affiliated Huai'an Hospital of Xuzhou Medical University, Huai'an, China.

Long noncoding RNA (lncRNA) may regulate the process of tumor formation. Although lncRNA CCAT2 has been identified as a key point in many diseases, its pathophysiological mechanism in lung adenocarcinoma remains unknown. We measured the expression level of CCAT2 in lung adenocarcinoma cells and normal lung epithelial cell line BEAS-2B by quantitative real-time polymerase chain reaction (qRT-PCR). Read More

Polydatin suppresses the development of lung inflammation and fibrosis by inhibiting activation of the NACHT domain-, leucine-rich repeat-, and pyd-containing protein 3 inflammasome and the nuclear factor-κB pathway after Mycoplasma pneumoniae infection.

J Cell Biochem 2018 Dec 12. Epub 2018 Dec 12.

Centre for Reproductive Medicine and Department of Laboratory Medicine, First Affiliated Hospital, Second Military Medical University, Shanghai, China.

Mycoplasma pneumoniae (MP) can infect both the upper and lower respiratory tracts. Polydatin (PD), a traditional Chinese medicine, is known to have anti-inflammation and antifibrosis properties. However, the protective effects of PD against MP pneumonia (MPP) remain unclear. Read More

Data-driven adult asthma phenotypes based on clinical characteristics are associated with asthma outcomes twenty years later.

Allergy 2018 Dec 13. Epub 2018 Dec 13.

Inserm, Univ. Grenoble Alpes, CNRS, IAB, Team of environmental epidemiology applied to reproduction and respiratory health, 38000, Grenoble, France.

Background: Research based on cluster analyses led to the identification of particular phenotypes confirming phenotypic heterogeneity of asthma. The long-term clinical course of asthma phenotypes defined by clustering analysis remains unknown, although it is a key aspect to underpin their clinical relevance. We aimed to estimate risk of poor asthma events between asthma clusters identified 20 years earlier. Read More

Prolongation of allograft survival by passenger donor regulatory T cells.

Am J Transplant 2018 Dec 12. Epub 2018 Dec 12.

Department of Surgery, University of Cambridge, School of Clinical Medicine, Cambridge, United Kingdom.

Tissue resident lymphocytes are present within many organs, and are presumably transferred at transplantation, but their impact upon host immunity is unclear. Here we examine whether transferred donor natural regulatory CD4 T cells (nT-regs) inhibit host alloimmunity and prolong allograft survival. Transfer of donor-strain lymphocytes was first assessed by identifying circulating donor-derived CD4 T cells in 21 consecutive human lung transplant recipients, with three patterns of chimerism apparent: transient; intermediate; and persistent (detectable for up to 6 weeks, 6 months, and beyond one year, respectively).

A case of pan-resistant burkholderia cepacia complex bacteraemic pneumonia, after lung transplantation treated with a targeted combination therapy.

Transpl Infect Dis 2018 Dec 12:e13034. Epub 2018 Dec 12.

Unidad de Cuidados Intensivos. Hospital Universitario Virgen Macarena, Sevilla.

We describe a case of one patient with cystic fibrosis who developed a pan-resistant Burkholderia Cepacia Complex rapidly progressive bacteraemic pneunonia, following bilateral lung transplantation. Patient was treated with a targeted combination antibiotic therapy (meropenem plus ceftazidime/avibactam plus high doses of nebulized colistimethate sodium). The disease evolution was complicated by multiple organ system dysfunction. Read More
