High heterogeneity in the blood pressure (BP) response to continuous positive airway pressure (CPAP) exists in patients with resistant hypertension (RH). Only nondipper normotensive and hypertensive patients exhibited BP reductions when treated with CPAP; the baseline BP dipping pattern has been proposed as a predictor of BP response to CPAP but has never been explored in patients with RH. This study aimed to assess the effect of CPAP on BP in subjects with RH with respect to BP dipping pattern or nocturnal hypertension. This is an ancillary study of the SARAH study. RH subjects with an apnea/hypopnea index (AHI) ≥ 15/h and who received CPAP treatment for 1 year were included. Subjects underwent a sleep study and ambulatory BP monitoring (ABPM) at baseline and at the 1-year follow-up. Eighty-nine RH subjects were included. The subjects were mainly male (77.5%) and obese, with a mean age of 66 years (25th-75th percentile; 59.0; 70.0) and an AHI of 32.7/h (25th-75th percentile; 25.0; 54.7). A total of 68.5% of participants were nondippers, and 71.9% had nocturnal hypertension. After 1 year of CPAP, no significant differences in ABPM parameters were observed between dippers and nondippers. According to nighttime BP, subjects with nocturnal normotension did not show significant changes in ABPM parameters, while nocturnal hypertensive subjects achieved a significant reduction in mean nighttime BP of -4.38 mmHg (-7.10 to -1.66). The adjusted difference between groups was 3.04 (-2.25 to 8.34), which was not significant. This study shows that the BP response to CPAP in patients with RH does not differ according to the BP dipping pattern (dipper and nondipper) and suggests a differential response according to the presence of nocturnal hypertension (ClinicalTrials.gov NCT03002558).Hypertension is one of the most prevalent chronic conditions and has been proven to be related to cognitive function. However, there is no evidence regarding the heterogeneity in cognitive trajectories among persons with hypertension. The aims of the current study were to characterize the heterogeneity in longitudinal trajectories of cognitive performance among Chinese middle-aged and older individuals with hypertension and to explore the potential determinants of trajectory memberships. Data from the 2011 to 2018 Chinese Health and Retirement Longitudinal Study (CHARLS) were utilized. Two cognitive measures of executive function and episodic memory were assessed, and conditional growth mixture modeling (GMM) was performed to identify the trajectories of cognitive performance and explore the related factors of cognitive change. The findings revealed three trajectory classes of executive function (stable, sharp decline, smooth decline) and two trajectory classes of episodic memory (stable, decline). Individuals with hypertension who had a higher educational level, moderate nighttime sleep duration, and lower depressive symptoms as well as those who reported consuming alcohol at least once a month were more likely to belong to the optimal stable executive function group. Subjects with a higher educational level, adequate daytime napping duration, and higher BMI were more likely to exhibit stable episodic memory over time. Other factors, including age, sex, community type, marital status, and hypertension treatment, exhibited class-specific effects on growth parameters of cognitive trajectory. Targeting intervention designation is proposed to ameliorate the burdens of cognitive impairment among individuals with hypertension.To prevent further spread of coronavirus disease 2019 (COVID-19), the Japanese government announced a state of emergency, resulting in major stress for the population. The aim of this study was to investigate a possible association between changes in daily stress and blood pressure (BP) in Japanese patients. We retrospectively investigated 748 patients with chronic disease who were treated by the Sagamihara Physicians Association to determine changes in stress during the COVID-19 state of emergency from 7 April to 31 May 2020. During the state of emergency, office BP significantly increased from 136.5 ± 17.5/78.2 ± 12.0 to 138.6 ± 18.6/79.0 ± 12.2 (p  less then  0.001 and p = 0.03, respectively). In contrast, home BP significantly decreased from 128.2 ± 10.3/75.8 ± 8.8 to 126.9 ± 10.2/75.2 ± 9.0 (p  less then  0.001 and p = 0.01, respectively), and the ratio of white coat hypertension was significantly increased (p  less then  0.001). Fifty-eight percent of patients worried about adverse effects of hypertension as a condition contributing to the severity and poor prognosis of COVID-19; decreased amounts of exercise and worsened diet compositions were observed in 39% and 17% of patients, respectively. In conclusion, a significant increase in office BP with the white coat phenomenon was observed during the state of emergency, as well as an increase in related stress. To prevent cardiovascular events, general practitioners should pay more attention to BP management during stressful global events, including the COVID-19 pandemic.This study aimed to identify the metabolomic alterations associated with hypertension (HTN) and the response of blood pressure (BP) to thiazide diuretics. A total of 50 participants previously untreated for HTN were prospectively recruited. After a 2-week lifestyle adjustment, 30 participants with systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg were classified into the HTN group and prescribed hydrochlorothiazide (HCTZ) at 50 mg per day for 2 weeks. The remaining 20 participants, who had relatively normal BP, were assigned to the normotension group. Metabolomic profiles related to the response of BP to thiazide diuretics were analyzed. A total of 73 differential metabolites were found to be associated with HTN, and 27 metabolites were significantly changed upon HCTZ treatment (HCTZ-sensitive metabolites). Among the identified metabolites, 7 (aspartate, histidine, C5-DC, C5-M-DC, C141, phosphatidylcholine ae C341, and phosphatidylcholine ae C343) were positively associated with HTN and decreased in abundance upon HCTZ treatment (HCTZ-reduced/HTN-associated metabolites). Moreover, multivariate analysis of 20 metabolites whose baseline levels were associated with the response of BP revealed that aspartate, glutamate, lysophosphatidylcholine C160, lysophosphatidylcholine C203, and sphingomyelin C241 were independently related to systolic BP reduction, and lysophosphatidylcholine C203 was independently associated with diastolic BP reduction. In conclusion, we identified 5 metabolites independently related to BP changes with HCTZ treatment. An advanced biomarker profile of thiazide-induced metabolomic changes may provide a clue with which to further explore the complex and mixed effects of thiazide treatment in a clinical setting.Spatial profiles of the tumor-immune microenvironment are associated with disease progression and clinicopathological factors in various cancers. WZ4003 Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer, where the presence of capsular invasion or angioinvasion determines the pathological diagnosis; however, little is known about the immune microenvironment profiles associated with the acquisition of invasive potential of FTC. In this study, we focused on FTC with minimal capsular invasion, and the spatially resolved immune microenvironment of FTC was studied in the discovery (n = 13) and validation cohorts (n = 40). CD8+ T cells, helper T cells, regulatory T cells, B cells, natural killer cells, tumor-associated macrophages, CD66+ granulocytes, mature dendritic cells, and mast cells were quantitatively evaluated in single tissue sections, via a 12-marker multiplex immunohistochemistry and image cytometry. Cell densities and compositions of immune cells were spatially stratified by six tissuproviding new insights into the mechanisms underlying its development and initial invasion.Epstein-Barr virus (EBV)-positive extranodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT lymphomas) were initially described in solid organ transplant recipients, and, more recently, in other immunodeficiency settings. The overall prevalence of EBV-positive MALT lymphomas has not been established, and little is known with respect to their genomic characteristics. Eight EBV-positive MALT lymphomas were identified, including 1 case found after screening a series of 88 consecutive MALT lymphomas with EBER in situ hybridization (1%). The genomic landscape was assessed in 7 of the 8 cases with a targeted high throughput sequencing panel and array comparative genomic hybridization. Results were compared to published data for MALT lymphomas. Of the 8 cases, 6 occurred post-transplant, 1 in the setting of primary immunodeficiency, and 1 case was age-related. Single pathogenic/likely pathogenic mutations were identified in 4 of 7 cases, including mutations in IRF8, BRAF, TNFAIP3, and SMARCA4. Other than TNFAIP3, these genes are mutated in less then 3% of EBV-negative MALT lymphomas. Copy number abnormalities were identified in 6 of 7 cases with a median of 6 gains and 2 losses per case, including 4 cases with gains in regions encompassing several IRF family or interacting genes (IRF2BP2, IRF2, and IRF4). There was no evidence of trisomies of chromosomes 3 or 18. In summary, EBV-positive MALT lymphomas are rare and, like other MALT lymphomas, are usually genetically non-complex. Conversely, while EBV-negative MALT lymphomas typically show mutational abnormalities in the NF-κB pathway, other than the 1 TNFAIP3-mutated case, no other NF-κB pathway mutations were identified in the EBV-positive cases. EBV-positive MALT lymphomas often have either mutations or copy number abnormalities in IRF family or interacting genes, suggesting that this pathway may play a role in these lymphomas.Kikuchi-Fujimoto disease (KFD) is a reactive lymphadenitis of unclear etiology. To understand the pathogenesis of KFD, we performed targeted RNA sequencing of a well-characterized cohort of 15 KFD specimens with 9 non-KFD lymphadenitis controls. Two thousand and three autoimmunity-related genes were evaluated from archived formalin-fixed paraffin-embedded lymph node tissue and analyzed by a bioinformatics approach. Differential expression analysis of KFD cases compared to controls revealed 44 significantly upregulated genes in KFD. Sixty-eight percent of these genes were associated with the type I interferon (IFN) response pathway. Key component of the pathway including nucleic acid sensors, IFN regulatory factors, IFN-induced antiviral proteins, IFN transcription factors, IFN-stimulated genes, and IFN-induced cytokines were significantly upregulated. Unbiased gene expression pathway analysis revealed enrichment of IFN signaling and antiviral pathways in KFD. Protein-protein interaction analysis and a molecular complex detection algorithm identified a densely interacting 15-gene module of type I IFN pathway genes. Apoptosis regulator IFI6 was identified as a key seed gene. Transcription factor target analysis identified enrichment of IFN-response elements and IFN-response factors. T-cell-associated genes were upregulated while myeloid and B-cell-associated genes were downregulated in KFD. CD123+ plasmacytoid dendritic cells (PDCs) and activated T cells were noted in KFD. In conclusion, KFD is mediated by an aberrant type I interferon response that is likely driven by PDCs and T cells.
