Is epistaxis associated with high blood pressure and hypertension? Propensity score matching study

Introduction: Arterial calcification is associated with vascular stiffness, which manifests with visit-to-visit blood pressure variability (VVBPV). Although media arterial calcification (MAC) is significantly associated with poor cardiovascular outcomes in kidney patients, the association in kidney transplant (KT) patients is unknown. Hypothesis: We hypothesize that MAC is associated with VVBPV in long-tern post-KT. Methods: Since MAC, which is detected from mammogram (MG) and determined by linear calcified breast arteries, is exclusively medial, female KT patients with ≥1 MG during pre-KT period were included in this study. VVBPV was examined by average successive variability (ASV), which is the average absolute difference between successive BP measured at 4, 12, 24, 36, and 48 weeks post-KT. After balancing patients with and without MAC by using propensity score matching based on age, diabetes, and obesity status, the association between MAC and systolic and diastolic VVBPV (VVSBPV and VVDBPV) at 48 weeks post-KT was tested by multiple linear regression (Figure1A&1B). Results: Of 51 patients, mean age±SD is 54±12 years, 21 had diabetes, and 21 were obese. Mean duration of follow-up was 47±9 years. Among 20 patients with MAC, mean VVSBPV was 20±14 mmHg; whereas, VVSBPV in non-MG group was 14±8 mmHg (mean difference -6± 3.0, p 0.06, 95%CI -12.03, 0.15). Mean VVDBPV in MG and non-MG groups were 12±5 and 11±5.6 mmHg, respectively (mean difference -1±1.6, p 0.41, 95%CI -4.44, 1.86). Laboratory-related bone and mineral metabolism were not different between both groups. On average, MG group had 8 mmHg higher VVSBPV compared to non-MG group (Coef. 3.62, p 0.02, 95%CI 1.16, 15.34). The MG group remained having higher VVDBPV but the magnitude of the association decreased and no statistical significance (Coef. 0.58, p 0.83, 95%CI -4.58, 5.73). Conclusions: Similar to non-transplant patients, KT recipients with pre-KT MAC had significant higher VVSBPV at the late post-KT.

Normal Sleep

Few studies have considered psychosocial characteristics when investigating the associations between sleep duration and blood pressure (BP). In this study, we took propensity score matching (PSM) to adjust for psychosocial characteristics when comparing BP between individuals with short sleep duration and those with normal sleep duration. A total of 429 participants were included. 72 participants with sleep duration ≤6 h and 65 participants with sleep duration >6 h were matched after PSM. We compared office BP, 24-hour BP, and prevalence of hypertension in the populations before and after PSM, respectively. In the unmatched population, participants with sleep duration ≤6 h were observed with higher office diastolic BP (DBP) and 24-h systolic BP (SBP)/DBP (all P < 0.05 ). In the matched populations, the differences between the two groups (sleep duration ≤6 h vs. sleep duration >6 h) in office DBP (88.4 ± 10.9 vs. 82.5 ± 11.1 mm Hg; P = 0.002 ), 24-h SBP (134.7 ± 12.0 vs. 129.3 ± 11.6 mm Hg; P = 0.009 ), and 24-h DBP (83.4 ± 9.9 vs. 78.1 ± 10.1 mm Hg; P = 0.002 ) become more significant. Participants with sleep duration ≤6 h only show higher prevalence of hypertension based on 24-h BP data, while analysis after PSM further revealed that these with sleep duration ≤6 h presented about 20% higher prevalence of elevated BP up to office diagnosed hypertension threshold. Therefore, psychosocial characteristics accompanied with short sleep duration should be fully valued in individuals at risks for elevated BP. This trial is registered with NCT03866226.

Patients With Diabetes

Background: Aldosterone excess in primary aldosteronism (PA) has been linked to insulin resistance, and diabetes mellitus has been associated with increased arterial stiffness and worse cardiovascular outcomes. However, the impact of diabetes on baseline and post-treatment arterial stiffness in patients with PA is unknown. Methods: This study prospectively enrolled 1071 PA patients, of whom 177 had diabetes and 894 did not. Clinical, biochemical, and brachial-ankle pulse wave velocity (baPWV) data were analyzed at baseline and 1 year after PA-specific treatment. After propensity score matching of age, sex, body mass index, systolic and diastolic blood pressure, hypertension duration, and number of antihypertensive medications, 144 patients with diabetes and 320 without diabetes were included for further analysis. Results: After propensity score matching, the baseline characteristics were balanced between the diabetes and nondiabetes groups except for fasting glucose, HbA1c, and lipid profiles. The patients with diabetes had significantly worse baseline baPWV compared with those without diabetes. After multivariable linear regression, the presence of diabetes mellitus remained a significant predictor of worse baseline mean baPWV (β: 46.3, 95% confidence interval: 2.9–89.7, p = 0.037). After 1 year of PA-specific treatment, only the nondiabetes group had significant recovery of mean baPWV (1661.8 ± 332.3 to 1565.0 ± 329.2 cm/s, p < 0.001; Δ = −96.8 ± 254.6 cm/s). In contrast, the diabetes group had less improvement (1771.2 ± 353.8 cm/s to 1742.0 ± 377.2 cm/s, p = 0.259; Δ = −29.2 ± 263.2 cm/s) even though the systolic and diastolic blood pressure significantly improved in both groups. Conclusion: The presence of diabetes mellitus in PA patients was associated with worse baseline and less post-treatment recovery of arterial stiffness.

Propensity Score Matching

Der vorliegende Beitrag geht der Frage nach, ob Schülerinnen und Schüler, die nach der vierten Klasse in Berlin in ein grundständiges Gymnasium wechseln, in Abhängigkeit vom Profil des besuchten Gymnasiums im Vergleich zu Grundschülern mit vergleichbaren Lernvoraussetzungen unterschiedliche Lernzuwächse im Leseverständnis, in Mathematik und Englisch erreichen. Auf der Datengrundlage der ELEMENT-Studie wurde die Leistungsentwicklung von Schülerinnen und Schülern an grundständigen Gymnasien (N = 1758) und Grundschulen (N = 3169) während der 5. und 6. Jahrgangsstufe mithilfe von Propensity Score Matching-Analysen (PSM) modelliert. Nach Kontrolle von leistungsrelevanten Unterschieden zwischen den Schülergruppen am Ende der 4. Jahrgangsstufe zeigten sich für das Leseverständnis am Ende der 6. Klasse keine statistisch signifikanten Unterschiede. Für die Mathematikleistung ließen sich Unterschiede lediglich zugunsten eines grundständigen Gymnasiums, das zum Untersuchungszeitpunkt noch kein spezifisches Profil entwickelt hatte, nachweisen. In der Domäne Englisch, in der die curricularen Unterschiede zwischen den Schulzweigen stärker akzentuiert sind, wurden positive Ergebnisse im Vergleich zu den Grundschulen für die so genannten Schnellläuferzüge, die englisch-bilingualen Klassen und das grundständige Gymnasium ohne spezifisches Profil ermittelt. Die Lernstände am Ende der 6. Klasse in den altsprachlichen Gymnasien fielen dagegen im Vergleich zu den Grundschulen geringer aus. Die Befunde widersprechen der Annahme, dass mit dem frühen Übergang auf ein grundständiges Gymnasium automatisch eine besondere Förderung der Lesefähigkeit und des mathematischen Verständnisses besonders leistungsfähiger Schülerinnen und Schüler erreicht werde. Die Ergebnisse zu den Englischleistungen weisen hingegen darauf hin, dass Unterschiede in der Leistungsentwicklung auftreten können, sofern die Aufteilung auf Schulen mit unterschiedlichen Bildungsprogrammen mit curricularen Unterschieden im Unterricht einhergeht. Methodische und inhaltliche Implikationen der Befunde und Grenzen ihrer Generalisierbarkeit werden diskutiert.

Validation studies of standard scales in the particular sample that one is studying are essential for accurate conclusions. We investigated the differences in answering patterns of the Brief-Symptom-Inventory (BSI), Transpersonal Trust Scale (TPV), Sense of Coherence Questionnaire (SOC), and a Social Support Scale (F-SoZu) for a matched sample of spiritually practicing (SP) and nonpracticing (NSP) individuals at two measurement points (t1, t2). Applying a sample matching procedure based on propensity scores, we selected two sociodemographically balanced subsamples of N = 120 out of a total sample of N = 431. Employing repeated measures ANOVAs, we found an intersample difference in means only for TPV and an intrasample difference for F-SoZu. Additionally, a group × time interaction effect was found for TPV. While Cronbach’s α was acceptable and comparable for both samples, a significantly lower test-rest-reliability for the BSI was found in the SP sample (rSP = .62; rNSP = .78). Thus, when researching the effects of spiritual practice, one should not only look at differences in means but also consider time stability. We recommend propensity score matching as an alternative for randomization in variables that defy experimental manipulation such as spirituality.
