Authors: Tari Haahtela, Juha Jantunen, Kimmo Saarinen, Erja Tommila, Erkka Valovirta, Tuula Vasankari, Mika J. Mäkelä
Journal: Allergy (2022)

In Finland, a systematic public health programme was implemented from 2008 to 2018 to mitigate the burden of allergic disorders by revisiting the prevention strategy. Allergy health and contacts with natural environment were emphasized to promote immunological and psychological resilience instead of poorly justified avoidance. Allergy management practices were improved and low-valued recommendations for care, for example for food allergy, were revised. Patients and families were empowered to use guided self-management to proactively stop symptom exacerbations. A professional non-governmental organization implemented the nationwide education for healthcare and patient NGOs for patients, families and lay public. In healthcare, the work supporting allergic patients and families was organized towards common goals and integrated into everyday work without extra costs. Reaching the predefined goals was followed by employing the national healthcare registers and questionnaire surveys. Governmental bodies contributed with kick-off funding, which was supplemented by private funding. International collaboration, for example with the European patient organization (EFA), increased awareness of the Finnish action and predisposed it for peer review. The 10-year results are favourable, patients are less disabled, practices and attitudes in healthcare have changed, and major cost savings have been obtained. Views of the lay public and patients are slow to move, however. Local multidisciplinary allergy teams were set up to continue the activities also after the Programme. Changes in environment and lifestyle in the last 50 years are the main reasons for the allergy rise. The Finnish experience may help to manage allergic diseases, improve nature relatedness in the fast-urbanizing world, combat nature loss and reduce the disease burden.

Journal: Journal for ImmunoTherapy of Cancer (2022)

Background Several studies have reported the incidence of immune-related adverse events (irAEs) as a predictor of the efficacy of anti-programmed cell death protein 1 antibodies in patients with cancer. However, immortal time bias has not always been fully addressed in these studies. In this retrospective multicenter study, we assessed the association between the incidence of irAEs and the efficacy of pembrolizumab in urothelial carcinoma (UC) using time-dependent analysis, an established statistical method to minimize immortal time bias. Methods The study included 176 patients with advanced UC who underwent pembrolizumab treatment at seven affiliated institutions between January 2018 and July 2020. Patients with irAEs were compared with those without irAEs in terms of overall survival (OS) and cancer-specific survival (CSS). Immortal time bias was eliminated by using time-dependent analysis. Results Of the 176 patients, irAEs occurred in 77 patients (43.8%), with a median of 60 days. The irAEs (+) cohort showed significantly favorable OS and CSS compared with the irAEs (−) cohort (p=0.018 and p=0.005, respectively), especially in the cohort with grade 1–2 irAEs (OS and CSS; p=0.003 and p=0.002, respectively). Multivariate analyses identified any irAEs and grade 1–2 irAEs as independent favorable prognostic factors for OS and CSS. Conclusion Even after minimizing immortal time bias by time-dependent analysis, the incidence of irAEs, especially grade 1–2 irAEs, could be a significant predictor of favorable prognoses in patients with UC who have undergone pembrolizumab treatment.

Correlation of total serum HDL particles with a predictor of mortality risk in idiopathic pulmonary fibrosis
Authors: Taro Yasuma, Corina N. D'Alessandro-Gabazza, Hajime Fujimoto, Tetsu Kobayashi, Esteban C. Gabazza
Journal: European Respiratory Journal (2022)

We read with great interest the article published in your journal by Barochia et al . [1]. The authors reported that the serum level of small high-density lipoprotein particles measured by nuclear magnetic resonance spectroscopy (S-HDLPNMR) is negatively associated with death or lung transplantation in idiopathic pulmonary fibrosis (IPF) [1]. The finding is consistent with the protective activity of high-density lipoprotein (HDL) in tissue injury and fibrosis reported in previous studies [2–5]. Measurement of serum total HDL particles may be potentially useful as a biomarker in idiopathic pulmonary fibrosis <https://bit.ly/3K7D3q6>
Cellular Memories — More Than Skin Deep
Authors: Thomas H. Leung, George Cotsarelis
Journal: New England Journal of Medicine (2022)

When wounds of intermediate depth occur, hair-follicle stem cells migrate to the wound and adopt the function, form, and gene-expression pattern of epidermal stem cells. However, a mouse model showed that these hair-follicle stem cells maintain an epigenetic memory that may be key to their improved capacity for faster healing of secondary wounds.

Reproducibility, validity, and reliability of the incremental step test for subjects with moderate to severe asthma
Authors: R.C.C. Barbosa, R.A. Silva, A.C. Lunardi, S.T.C. Silva, S.D. Corso, A.J. Fonseca, R. Stelmach, C.R.F. Carvalho
Journal: Pulmonology (2022)

We investigated the measurement properties of the incremental step test in subjects with moderate to severe asthma. Subjects with moderate to severe persistent asthma were recruited from a tertiary university hospital specializing in treating severe asthma. All subjects performed one cardiopulmonary exercise test (CPET) and two incremental step tests (IST) in random sequences. Pulmonary gas exchange was measured during all exercise tests. The measurement properties investigated were reliability by intraclass correlation coefficient (ICC), measurement error by the standard error of measurement and minimum detectable difference, construct validity by Pearson's correlation, and interpretability by the ceiling and floor effects. Fifty subjects (38 females, mean [SD], age 43.7 [11.6] yr, % FEV1 70 [14.3], BMI 28.5 [5.3] kg/m2) completed the study. The peak oxygen uptake (peak VO2) for the CPET was 27.6 [±6.8] ml/kg/min, for the first IST was 22.3 [±5.3] ml/kg/min and for the second IST was 23.3 [±5.3] ml/kg/min. The IST presented excellent reliability (ICC=0.93, CI95% 0.88-0.96), very good measurement error (2.5%), and construct validity for peak VO2 measurement compared to the CPET (r = 0.85; p < 0.001) to assess exercise capacity in subjects with moderate to severe asthma, with appropriate ceiling (10%) and floor (0%) effects. The IST presented excellent reliability and very good measurement error and validity to assess exercise capacity in subjects with moderate to severe asthma, without ceiling or floor effects.
Epigenetic modifications in spinal ligament aging
Authors: Qian Xiang, Yongzhao Zhao, Jialiang Lin, Shuai Jiang, Weishi Li
Journal: Ageing Research Reviews (2022)

Spinal stenosis is a common degenerative spine disorder in the aged population and the spinal ligament aging is a main contributor to this chronic disease. However, the underlying mechanisms of spinal ligament aging remain unclear. Epigenetics is the study of heritable and reversible changes in the function of a gene or genome that occur without any alteration in the primary DNA sequence. Epigenetic alterations have been demonstrated to play crucial roles in age-related diseases and conditions, and they are recently studied as biomarkers and therapeutic targets in the field of cancer research. The main epigenetic modifications, including DNA methylation alteration, histone modifications as well as dysregulated noncoding RNA modulation, have all been implicated in spinal ligament aging diseases. DNA methylation modulates the expression of critical genes including WNT5A, GDNF, ACSM5, miR-497 and miR-195 during spinal ligament degeneration. Histone modifications widely affect gene expression and obvious histone modification abnormalities have been found in spinal ligament aging. MicroRNAs (miRNAs), long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) exert crucial regulating effects on spinal ligament aging conditions via targeting various osteogenic or fibrogenic differentiation related genes. To our knowledge, there is no systematic review yet to summarize the involvement of epigenetic mechanisms of spinal ligament aging in degenerative spinal diseases. In this study, we systematically discussed the different epigenetic modifications and their potential functions in spinal ligament aging process.

Authors: Jill Kolesar, Spencer Peh, Levin Thomas, Gayathri Baburaj, Nayonika Mukherjee, Raveena Kantamneni, Shirley Lewis, Ananth Pai, Karthik S. Udupa, Naveena Kumar AN, Vivek M. Rangnekar, Mahadev Rao
Journal: Molecular Cancer (2022)

The advent of molecular profiling has revolutionized the treatment of lung cancer by comprehensively delineating the genomic landscape of the epidermal growth factor receptor (EGFR) gene. Drug resistance caused by EGFR mutations and genetic polymorphisms of drug metabolizing enzymes and transporters impedes effective treatment of EGFR mutant and resistant lung cancer. This review appraises current literature, opportunities, and challenges associated with liquid biopsy and pharmacogenomic (PGx) testing as precision therapy tools in the management of EGFR mutant and resistant lung cancers. Liquid biopsy could play a potential role in selection of precise tyrosine kinase inhibitor (TKI) therapies during different phases of lung cancer treatment. This selection will be based on the driver EGFR mutational status, as well as monitoring the development of potential EGFR mutations arising during or after TKIs treatment, since some of these new mutations may be druggable targets for alternative TKIs. Several studies have identified the utility of liquid biopsy in the identification of EGFR driver and acquired resistance with good sensitivities for various blood-based biomarkers. With a plethora of sequencing technologies and platforms available currently, further evaluations using randomized controlled trials (RCTs) in multicentric, multiethnic and larger patient cohorts could enable optimization of liquid-based assays for the detection of EGFR mutations, and support testing of CYP450 enzymes and drug transporter polymorphisms to guide precise dosing of EGFR TKIs.

Journal: Circulation Research (2022)

Background: The transcription factor BACH1 (BTB and CNC homology 1) suppressed endothelial cells (ECs) proliferation and migration and impaired angiogenesis in the ischemic hindlimbs of adult mice. However, the role and underlying mechanisms of BACH1 in atherosclerosis remain unclear. Methods: Mouse models of atherosclerosis in endothelial cell (EC)-specific-Bach1 knockout mice were used to study the role of BACH1 in the regulation of atherogenesis and the underlying mechanisms. Results: Genetic analyses revealed that coronary artery disease-associated risk variant rs2832227 was associated with BACH1 gene expression in carotid plaques from patients. BACH1 was upregulated in ECs of human and mouse atherosclerotic plaques. Endothelial Bach1 deficiency decreased turbulent blood flow- or western diet-induced atherosclerotic lesions, macrophage content in plaques, expression of endothelial adhesion molecules (ICAM1 [intercellular cell adhesion molecule-1] and VCAM1 [vascular cell adhesion molecule-1]), and reduced plasma TNF-α (tumor necrosis factor-α) and IL-1β levels in atherosclerotic mice. BACH1 deletion or knockdown inhibited monocyte–endothelial adhesion and reduced oscillatory shear stress or TNF-α-mediated induction of endothelial adhesion molecules and/or proinflammatory cytokines in mouse ECs, human umbilical vein ECs, and human aortic ECs. Mechanistic studies showed that upon oscillatory shear stress or TNF-α stimulation, BACH1 and YAP (yes-associated protein) were induced and translocated into the nucleus in ECs. BACH1 upregulated YAP expression by binding to the YAP promoter. BACH1 formed a complex with YAP inducing the transcription of adhesion molecules. YAP overexpression in ECs counteracted the antiatherosclerotic effect mediated by Bach1-deletion in mice. Rosuvastatin inhibited BACH1 expression by upregulating microRNA let-7a in ECs, and decreased Bach1 expression in the vascular endothelium of hyperlipidemic mice. BACH1 was colocalized with YAP, and the expression of BACH1 was positively correlated with YAP and proinflammatory genes, as well as adhesion molecules in human atherosclerotic plaques. Conclusions: These data identify BACH1 as a mechanosensor of hemodynamic stress and reveal that the BACH1-YAP transcriptional network is essential to vascular inflammation and atherogenesis. BACH1 shows potential as a novel therapeutic target in atherosclerosis.
CADASIL mutations sensitize the brain to ischemia via spreading depolarizations and abnormal extracellular potassium homeostasis

Cerebral autosomal dominant arteriopathy, subcortical infarcts, and leukoencephalopathy (CADASIL) is the most common monogenic form of small vessel disease characterized by migraine with aura, leukoaraiosis, strokes, and dementia. CADASIL mutations cause cerebrovascular dysfunction in both animal models and humans. Here, we showed that 2 different human CADASIL mutations (Notch3 R90C or R169C) worsen ischemic stroke outcomes in transgenic mice; this was explained by the higher blood flow threshold to maintain tissue viability compared with that in wild type (WT) mice. Both mutants developed larger infarcts and worse neurological deficits compared with WT mice, regardless of age or sex after filament middle cerebral artery occlusion. However, full-field laser speckle flowmetry during distal middle cerebral artery occlusion showed comparable perfusion deficits in mutants and their respective WT controls. Circle of Willis anatomy and pial collateralization also did not differ among the genotypes. In contrast, mutants had a higher cerebral blood flow threshold, below which infarction ensued, suggesting increased sensitivity of brain tissue to ischemia. Electrophysiological recordings revealed a 1.5- to 2-fold higher frequency of peri-infarct spreading depolarizations in CADASIL mutants. Higher extracellular K+ elevations during spreading depolarizations in the mutants implicated a defect in extracellular K+ clearance. Altogether, these data reveal a mechanism of enhanced vulnerability to ischemic injury linked to abnormal extracellular ion homeostasis and susceptibility to ischemic depolarizations in CADASIL.
Differentiating COPD and asthma using quantitative CT imaging and machine learning
Authors: Amir Moslemi, Konstantina Kontogianni, Judith Brock, Susan Wood, Felix Herth, Miranda Kirby
Journal: European Respiratory Journal (2022)

There are similarities and differences between chronic obstructive pulmonary disease (COPD) and asthma patients in terms of computed tomography (CT) disease-related features. Our objective was to determine the optimal subset of CT imaging features for differentiating COPD and asthma using machine learning.COPD and asthma patients were recruited from Heidelberg University Hospital (Heidelberg, Germany). CT was acquired and 93 features were extracted: percentage of low-attenuating area below -950 HU (LAA950), low-attenuation cluster (LAC) total hole count, estimated airway wall thickness for an idealised airway with an internal perimeter of 10 mm (Pi10), total airway count (TAC), as well as airway inner/outer perimeters/areas and wall thickness for each of five segmental airways, and the average of those five airways. Hybrid feature selection was used to select the optimum number of features, and support vector machine learning was used to classify COPD and asthma.95 participants were included (n=48 COPD and n=47 asthma); there were no differences between COPD and asthma for age (p=0.25) or forced expiratory volume in 1 s (p=0.31). In a model including all CT features, the accuracy and F1 score were 80% and 81%, respectively. The top features were: LAA950, outer airway perimeter, inner airway perimeter, TAC, outer airway area RB1, inner airway area RB1 and LAC total hole count. In the model with only CT airway features, the accuracy and F1 score were 66% and 68%, respectively. The top features were: inner airway area RB1, outer airway area LB1, outer airway perimeter, inner airway perimeter, Pi10, TAC, airway wall thickness RB1 and TAC LB10.COPD and asthma can be differentiated using machine learning with moderate-to-high accuracy by a subset of only seven CT features.

Ageing with HIV
Authors: None The Lancet Healthy Longevity
Journal: The Lancet Healthy Longevity (2022)

The efficacy of antiretroviral therapy (ART) and the success of global treatment programmes has meant that, provided individuals have access to care, HIV infection is no longer a life-limiting infection. However, with this success comes unexpected consequences: a growing population of older people with HIV (normally defined as those aged 50 years or older). This population is increasing because young people with HIV are surviving and ageing, and an increasing number of older people are acquiring HIV.
