The primary objective of this analysis is to assess if greater exposure to any major antihypertensive drug class was associated with reduced primary composite outcome events in SPRINT (Systolic Blood Pressure Intervention Trial).

This is a secondary analysis of the SPRINT trial evaluating whether longitudinal, time varying exposure to any major antihypertensive drug class had any impact on primary outcome events, after adjusting for effects of randomization arm, time varying achieved systolic blood pressure, other drug class exposure, and baseline characteristics.

Nine thousand two hundred fifty-two participants were included. After adjustments, exposure of one year or greater to thiazide-type diuretics or renin-angiotensin system blockers was associated with significantly fewer primary events than exposure of less than one year (hazard ratio, 0.78 [95% CI, 0.64-0.94]). There was no significant difference with longer versus shorter exposure to calcium channel blockers. Greater exposure to beta-blockers s was associated with increased cardiovascular events.In this interview, Professor Susan Gasser speaks with Storm Johnson, commissioning editor for Epigenomics, on her research on genome stability, epigenetic regulation and chromatin organization, as well as her work supporting women in research. Susan Gasser completed her BA at the University of Chicago, with an honors thesis in biophysics, and her PhD in biochemistry at the University of Basel in 1982, with Gottfried Schatz. She was a postdoc with Ulrich Laemmli at the University of Geneva, which initiated her career-long interest in chromosomes and chromatin structure. She established her own laboratory at the Swiss Institute for Experimental Cancer Research (ISREC) in 1986, focusing on chromatin organization in budding yeast, combining genetics, microscopy and biochemical approaches to understanding silent chromatin and telomeres. In 2001, she was named professor of molecular biology at the University of Geneva and expanded her laboratory's pioneering use of high-resolution time-lapse fluorescence microscopyed the careers of women scientists in Europe and Japan.Aim To characterize the actionable biomarker for leukemic transformation (LT) of myeloproliferative neoplasms (MPNs) at the DNA damage repair promoter methylation level. Materials & methods Bioinformatic analysis and experimental validation were performed to identify the MPNs-LT specific biomarker out of the promoter methylation of 236 DNA damage repair genes with GSE42042 dataset and an in-house cohort of 80 MPNs. Results Hypermethylation of BRCA2 promoter was characterized as the JAK2 mutation-independent epigenetic marker for MPNs-LT and repressed mRNA and protein expression, leading to olaparib hypersensitivity in the leukemic cells from MPNs-LT. Conclusion Expressional silence of BRCA2 by promoter methylation compels the homologous recombination deficiency and vulnerability to PARP inhibition and serves as an actionable marker for targeted therapy for MPNs-LT.Aim This study aimed to explore the effects of low-dose chemotherapy in the tumor microenvironment (TME) on a gastric cancer xenograft and its antitumor activity combined with the anti-PD-1 antibody. Materials & methods Mice with gastric cancer were divided into four groups. The body weight and tumor volume of the mice were recorded. The TME was analyzed using flow cytometry. Results Low-dose paclitaxel increased the PD-L1 expression level and the number of CD8+ T cells, but not the CD4+ T and myeloid-derived suppressor cells or PD-1+ CD8+ T cells in the TME. Low-dose 5-fluorouracil reduced the number of myeloid-derived suppressor cells and PD-1+ CD8+ T cells, but the PD-L1 expression level and the number of CD4+ T and CD8+ T cells did not change in the TME. The anti-PD-1 antibody inhibited tumor growth, but the combination therapy did not show superior antitumor activity. Conclusion Low-dose chemotherapy altered the TME but failed to improve the responses to the anti-PD-1 antibody.Aim To compare the efficacy and safety of first-line chemotherapy (Chemo) plus immune checkpoint inhibitors (ICIs) or bevacizumab (Bev) in advanced non-squamous non-small-cell lung cancer without EGFR mutations or ALK fusions. Methods A network meta-analysis was conducted to synthesize relative treatment outcomes. Results Chemo + ICIs is superior to Chemo + Bev in both overall survival (hazard ratio 0.92; 95% CI 0.88-0.96) and progression-free survival (hazard ratio 0.93; 95% CI 0.90-0.97), with comparable severe adverse events. However, for patients with liver metastasis, Chemo + Bev has a 59.8% probability of providing better overall survival benefit. For specific regimens, pembrolizumab + Chemo showed an absolute advantage over other regimens. Conclusion First-line Chemo + ICIs is superior to Chemo + Bev in advanced non-squamous non-small-cell lung cancer except for patients with liver metastasis.The major obstacles observed in current chemotherapy are severe adverse effects, narrow therapeutic indexes and multidrug resistance. Anticancer phytochemicals are extracted and purified from natural plants, providing alternative therapeutic approaches with recognized biomedical benefits. However, poor bioavailability, high dose requirements and non-specific targeting have made those molecules less effective. To tackle those issues, liposomal nanovesicles for phytochemical delivery are taken into consideration for improving the therapeutic effectiveness by increasing transportation across cell barriers and conferring attractive cancer-specific targeting capabilities. In the present review, the liposomal approaches of anticancer phytochemicals are discussed, and recent advances in these formulations applied to cancer phytotherapy are further reviewed by an informed approach.In this interview, Dr Jaclyn Goodrich speaks with Storm Johnson, Commissioning Editor for Epigenomics, on her work to date on environmental epigenetics and the impact of toxic exposures on susceptible populations.

ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) compared an initial invasive treatment strategy (INV) with an initial conservative strategy in 5179 participants with chronic coronary disease and moderate or severe ischemia. The ISCHEMIA research program included a comprehensive quality-of-life (QOL) substudy.

In 1819 participants (907 INV, 912 conservative strategy), we collected a battery of disease-specific and generic QOL instruments by structured interviews at baseline; at 3, 12, 24, and 36 months postrandomization; and at study closeout. Assessments included angina-related QOL (19-item Seattle Angina Questionnaire), generic health status (EQ-5D), depressive symptoms (Patient Health Questionnaire-8), and, for North American patients, cardiac functional status (Duke Activity Status Index).

Median age was 67 years, 19.2% were female, and 15.9% were non-White. The estimated mean difference for the 19-item Seattle Angina Questionnaire Summary scorerandomization (11.5%-12.8%) and was unaffected by treatment assignment.

In the ISCHEMIA comprehensive QOL substudy, patients with more frequent baseline angina reported greater improvements in the symptom, physical functioning, and psychological well-being dimensions of QOL when treated with an invasive strategy, whereas patients who had rare/absent angina at baseline reported no consistent treatment-related QOL differences.

The apparent simplicity of breathing belies a complex neural control system, the breathing central pattern generator (bCPG), that exhibits diverse operational modes to regulate gas exchange and coordinate breathing with an array of behaviors. In this review, we focus on selected advances in our understanding of the bCPG. At the core of the bCPG is the preBötzinger complex (preBötC), which drives inspiratory rhythm via an unexpectedly sophisticated emergent mechanism. Synchronization dynamics underlying preBötC rhythmogenesis imbue the system with robustness and lability. These dynamics are modulated by inputs from throughout the brain and generate rhythmic, patterned activity that is widely distributed. The connectivity and an emerging literature support a link between breathing, emotion, and cognition that is becoming experimentally tractable. These advances bring great potential for elucidating function and dysfunction in breathing and other mammalian neural circuits.Nervous system activity regulates development, homeostasis, and plasticity of the brain as well as other organs in the body. These mechanisms are subverted in cancer to propel malignant growth. In turn, cancers modulate neural structure and function to augment growth-promoting neural signaling in the tumor microenvironment. Approaching cancer biology from a neuroscience perspective will elucidate new therapeutic strategies for presently lethal forms of cancer. In this review, we highlight the neural signaling mechanisms recapitulated in primary brain tumors, brain metastases, and solid tumors throughout the body that regulate cancer progression.Surface charge density and distribution play an important role in almost all interfacial processes, influencing, for example, adsorption, colloidal stability, functional material activity, electrochemical processes, corrosion, nanoparticle toxicity, and cellular processes such as signaling, absorption, and adhesion. Understanding the heterogeneity in, and distribution of, surface and interfacial charge is key to elucidating the mechanisms underlying reactivity, the stability of materials, and biophysical processes. Atomic force microscopy (AFM) and scanning ion conductance microscopy (SICM) are highly suitable for probing the material/electrolyte interface at the nanoscale through recent advances in probe design, significant instrumental (hardware and software) developments, and the evolution of multifunctional imaging protocols. Here, we assess the capability of AFM and SICM for surface charge mapping, covering the basic underpinning principles alongside experimental considerations. We illustrate and compare the use of AFM and SICM for visualizing surface and interfacial charge with examples from materials science, geochemistry, and the life sciences.
