Diagnosis Of Hypertension

Tooth loss is closely associated with suboptimal oral care. Suboptimal oral care can facilitate local infections. These can lead to systemic inflammation and endothelial dysfunction, which are important pathological mechanisms of hypertension. The aim of this study was to investigate the link between tooth loss and the risk of hypertension. From the national health insurance system-health screening cohort in Korea, 19,680 participants who underwent three or more health examinations, including blood pressure measurements, between January 2003 and December 2008, without any history or diagnosis of hypertension were included in this study. Hypertension was defined as the diagnosis of hypertension (International Classification of Diseases-10 code “I10–11”) accompanied by the prescription of an antihypertensive agent or at least one health examination result of blood pressure of ≥140/90 mmHg. Kaplan-Meier survival curves with the log-rank test were used to evaluate the relationship between oral hygiene indicators and the incidence of hypertension. Cox proportional hazard models were applied to determine the association between oral hygiene indicators and the development of hypertension. During a median follow-up of 7.4 years, 1,853 patients developed hypertension. The estimated incidence of hypertension within seven years was 8.8%. Multivariable analysis confirmed a significant relationship between the number of lost teeth and hypertension (hazard ratio: 2.26; 95% confidence interval [1.24–4.10], p = 0.007, p for trend = 0.005). There was a positive association between the number of lost teeth and the risk of hypertension in a longitudinal research. In conclusion, the number of lost teeth may be associated with the risk of development of hypertension.

Introduction. Tooth loss is associated with poor oral hygiene. During insufficient oral sanitation, focal infection and inflammation can occur and these reactions may induce systemic inflammation. Systemic inflammatory reaction may be related to the degeneration of dopamine neurons in the substantia nigra. We hypothesized that tooth loss is related to increased risk of new-onset Parkinson’s disease. Methods. Between 2003 and 2006, we included 153,165 participants from the national health insurance system-health screening cohort in Korea. The incidence of new-onset Parkinson’s disease was defined as International Classification of Diseases-10 code “G20,” accompanying the prescription records for any anti-Parkinson’s disease medication. Results. Approximately 19.9% of the included participants had periodontal disease. After a median duration of 10.4 years, 1,227 (0.8%) cases of new-onset Parkinson’s disease were noted. The number of tooth loss was positively related to an increased risk of new-onset Parkinson’s disease. Contrastingly, the frequency of tooth brushings and dental clinic visits for any causes as well as competent dental care were negatively related to the development of new-onset Parkinson’s disease. In multivariable analysis, the number of tooth loss (≥15) was positively related to new-onset Parkinson’s disease development (hazard ratio: 1.38, 95% confidence interval (1.03–1.85), p=0.029, p for trend = 0.043) after adjusting variables. Conclusion. Our study demonstrated that the number of tooth loss was positively correlated with a higher risk of new-onset Parkinson’s disease development in a longitudinal study setting. Increased number of tooth loss may be an important risk indicator of new-onset Parkinson’s disease.

Abstract Purpose The association between height and the risk of developing primary brain malignancy remains unclear. We evaluated the association between height and risk of primary brain malignancy based on a nationwide population-based database of Koreans. Methods Using data from the Korean National Health Insurance System cohort, 6,833,744 people over 20 years of age that underwent regular national health examination were followed from January 2009 until the end of 2017. We documented 4,771 cases of primary brain malignancy based on an ICD-10 code of C71 during the median follow-up period of 7.30 years and 49,877,983 person-years. Results When dividing the population into quartiles of height for each age group and sex, people within the highest height quartile had a significantly higher risk of brain malignancy, compared to those within the lowest height quartile (HR 1.21 CI 1.18–1.32) after adjusting for potential confounders. We also found that the risk of primary brain malignancy increased in proportion with the quartile increase in height. After analyzing subgroups based on older age (≥ 65) and sex, we found positive relationships between height and primary brain malignancy in all subgroups. Conclusions This study is the first to suggest that height is associated with increased risk of primary brain malignancy in the East-Asian population. Further prospective and larger studies with precise designs are needed to validate our findings.

Background: Elevated blood pressure (BP) in the first 24 hours of admission of acute intracerebral hemorrhage (ICH) has been the focus of intensive therapeutic investigation, although early intensive BP lowering addresses a concern about development of acute kidney injury (AKI). However, it is unclear as to the effect of BP measure including the absolute BP reduction and increased BP variability on AKI in patients with acute ICH. Methods: We retrieved data of consecutive patients with acute ICH from our prospective stroke registry between July 2015 and August 2017. We excluded patients with preexisting end-stage renal disease or in-hospital death within 24 hours. The primary outcome was AKI within 7days after admission defined using the AKI Network criteria. We recorded BP on emergency department arrival and for every 1 hour from 1 to 24 hours after admission (25 measurements). We measured mean systolic BP (SBP) and maximum minus minimum SBP within both 12 hours and 24 hours, and also quantified SBP variabilities (SBPV) including standard deviation, coefficient of variation, successive variation, and average real variability. Results: Among 361 patients with ICH (age 72.7±12.8, male 55%, non-lobar 76%), 31 (9%) developed AKI. For all SBP measure, the 12-hour SBP reduction was associated with the increased risk of AKI in multivariable analysis (odds ratio [per10 mmHg increase] 1.30; 95% CI 1.10-1.35). There was no significant association between the SBP variability and risk of AKI. The area under the receiver operating characteristic curve of the 12-hour SBP reduction for predicting AKI was 0.75. The association between the 12-hour SBP reduction and AKI was not modified by preexisting chronic kidney disease (interaction P=0.40). Conclusion: Early BP reduction in the first 12 hours of admission contributed to the risk of AKI in acute ICH. This may have clinical implication to avoid excess absolute BP reduction in patients with acute ICH.

Purpose Patients with cancer are at increased risk of venous thromboembolism (VTE). Laboratory tests measuring the overall thrombophilic tendency might be useful to assess VTE risk. The aim of this study was to investigate thrombin generation, a key process in hemostasis, as predictor of cancer-associated VTE. Patients and Methods The Vienna Cancer and Thrombosis Study (CATS) is a prospective observational cohort study of patients with newly diagnosed cancer or progression of disease after remission. The study end point is occurrence of objectively confirmed symptomatic or fatal VTE within a follow-up period of 2 years. Thrombin generation was measured with a commercially available assay. Results One thousand thirty-three patients with malignancies of the breast (n = 151), lung (n = 148), upper (n = 44) and lower gastrointestinal tract (n = 125), pancreas (n = 67), kidney (n = 34), prostate (n = 122), and brain (n = 134) or lymphoma (n = 126), multiple myeloma (n = 26), and other tumor types (n = 56) were observed for a median observation period of 517 days. VTE occurred in 77 patients (7.5%). Patients with elevated peak thrombin (defined as values ≥ 611 nM thrombin, representing the 75th percentile of the total study population) had an increased risk of VTE with a hazard ratio of 2.1 (95% CI, 1.3 to 3.3, P = .002) in multivariable analysis including age, sex, surgery, chemotherapy, and radiotherapy. The cumulative probability of developing VTE after 6 months was significantly higher in patients with elevated peak thrombin than in those with lower peak thrombin (11% v 4%; log-rank test: P = .002). Conclusion Measurement of thrombin generation may help identify patients with cancer at high risk of VTE.

Despite excellent loco-regional control by multimodal treatment of locally advanced rectal cancer, a substantial portion of patients succumb to this disease. As many treatment effects are mediated via reactive oxygen species (ROS), we evaluated the effect of single nucleotide polymorphisms (SNPs) in ROS-related genes on clinical outcome. Based on the literature, eight SNPs in seven ROS-related genes were assayed. Eligible patients (n = 287) diagnosed with UICC stage II/III rectal cancer were treated multimodally starting with neoadjuvant radiochemotherapy (N-RCT) according to the clinical trial protocols of CAO/ARO/AIO-94, CAO/ARO/AIO-04, TransValid-A, and TransValid-B. The median follow-up was 64.4 months. The Ser326Cys polymorphism in the human OGG1 gene affected clinical outcome, in particular cancer-specific survival (CSS). This effect was comparable in extent to the ypN status, an already established strong prognosticator for patient outcome. Homozygous and heterozygous carriers of the Cys326 variant (n = 105) encountered a significantly worse CSS (p = 0.0004 according to the log-rank test, p = 0.01 upon multiple testing adjustment). Cox regression elicited a hazard ratio for CSS of 3.64 (95% confidence interval 1.70–7.78) for patients harboring the Cys326 allele. In a multivariable analysis, the effect of Cys326 on CSS was preserved. We propose the genetic polymorphism Ser326Cys as a promising biomarker for outcome in rectal cancer.

Abstract Background/Introduction Lowering blood pressure is very beneficial in reducing the risk of cardiovascular morbidity and mortality. But, the extent of optimal target blood pressure in hypertensive patients is still controversial. Purpose The objectives of this study were to assess the level of proper systolic and diastolic blood pressure to prevent cardiovascular events in older and younger patients. Methods We used the National Sample Cohort from the National Health Insurance Service of 2007 to 2013 in Korea and analyzed data from 44,462 hypertensive patients aged from 20 to 84, treated with one or more antihypertensive agents and participated at least one general health examination. Achieved systolic and diastolic blood pressure (SBP/DBP) were categorized by exclusive average achieved SBP (<120, <130, <140, <150, and ≥150 mmHg) and DBP (<70, <80, <90, <100, and ≥100 mmHg) categories using the blood pressure measurements of one or more available health examinations. The primary outcome was defined as composite, which was the first occurred event among admissions of myocardial infarction, stroke, and heart failure or cardiovascular death. Secondary outcomes were individual components of composite outcome and all-cause death. Results Of 44,462 patients, 5,478 (12.3%), 13,410 (30.2%), 15,021 (33.8%), 7,051 (15.9%), and 3,502 (7.9%) patients achieved SBP <120 mm Hg, 120–129 mm Hg, 130–139 mm Hg, 140–149 mm Hg, and ≥150 mm Hg, respectively. During the median follow-up of 6.8 years, 2,151 (4.8%) died by all-cause of death, and 2,463 (5.5%) met the criteria of composite outcome. In elderly patients, compared with achieved SBP 120–129 (reference), there was no significant increase in risk at SBP 130–139 mm Hg and 140–149 mm Hg, but SBP 150 mm Hg or more was positively associated with significant risk of composite outcome and all-cause death, with HR of 1.29 (95% CI, 1.11–1.51) and 1.66 (95% CI, 1.43–1.92), respectively (Figure). On the other hand, in younger patients, the risk for incidence of composite outcome was significantly increased both at SBP 140–149 mm Hg (HR, 1.39; 95% CI, 1.11–1.73) and 150 mm Hg or more (HR, 2.00; 95% CI, 1.53–2.62) In addition, an achieved SBP 130 mm Hg and more was also significantly associated with all-cause death with HR of 1.27 (95% CI, 1.00–1.62). Compared with 120–129 mm Hg, elderly patients who had achieved SBP less than 120 mm Hg were more likely to have increased risk for composite outcome (HR, 1.29; 95% CI, 1.10–1.52), but not in younger patients (HR, 1.01; 95% CI, 0.78–1.30). Conclusion In conclusion, an intensive lowering of blood pressure is more likely to increase the risk rather than to prevent major cardiovascular events and all-cause death, particularly in older than younger. Therefore, an intensive blood pressure lowering of SBP/DBP below 120/70 mm Hg in the elderly should be avoided.

Data regarding health behavior-related factors and systolic or diastolic blood pressure to evaluate the association between blood pressure and kidney cancer are lacking. Using nationally representative data from the Korean National Health Insurance System, 9 746 445 participants without kidney cancer between January 1, 2006 and December 31, 2009 were followed up until December 31, 2017 to obtain data regarding cancer incidence. Participants were categorized, according to blood pressure, as normal (<120/80 mm Hg), elevated (120–129/<80 mm Hg), and hypertensive (≥130/80 mm Hg) with or without antihypertensive medication, according to the 2017 American College of Cardiology and American Heart Association blood pressure guidelines. Kidney cancer was noted in 11 083 participants during the 8-year follow-up. Participants with hypertension were at higher risk for kidney cancer than those without hypertension. Participants with hypertension using medication had a higher cancer risk than those not using medication and those with elevated blood pressure. The risk of kidney cancer significantly increased with higher systolic or diastolic blood pressure, in a dose-dependent manner, even after adjusting for antihypertensive medication use. Therefore, hypertension and high systolic or diastolic blood pressure, compared with normal blood pressure, were associated with an increased risk of kidney cancer.

A non-dipper pattern of high blood pressure is associated with increased risk of organ damage and cardiovascular disease in patients with hypertension. The aim of the study was to evaluate the left ventricular (LV) remodeling and function and arterial stiffness in a dipper/non-dipper pattern of high blood pressure in patients with hypertension. A total of 183 hypertensive patients with no history of adverse cardiovascular events were divided into two groups based on 24 hours ambulatory blood pressure monitoring (ABPM): 66 patients with a dipper pattern and 117 patients with non-dipper pattern. Detailed transthoracic echocardiogram was performed and analyzed with advance speckle tracking 3-orthogonal direction strain analysis to assess LV systolic function and tissue Doppler-derived E/E′ for LV diastolic function assessment. Cardio ankle vascular index (CAVI) was used to evaluate arterial stiffness. Compared with patients with dipper hypertension, those with non-dipper hypertension had increased LV mass index, higher prevalence of eccentric and concentric LV hypertrophy, more impaired LV diastolic and systolic function and peripheral arterial stiffness. Multivariable analysis revealed that a non-dipper pattern was independently associated with LV systolic dysfunction evaluated by speckle tracking-derived strain analysis. In conclusion, a non-dipper pattern of hypertension is an independent risk factor for LV systolic dysfunction. Treatment that could reverse this non-dipper pattern may reduce cardiac damage in these patients.

Cystic fibrosis (CF) is the most common severe autosomal recessive disease in the Caucasian population. Although it remains incurable, it is currently possible to extend the life expectancy of patients with modern therapeutic possibilities. Given the medical issues that a child with CF faces, oral health may be perceived as being of lesser importance. Thus, the establishment of good dietary and oral hygiene practices may not take place, leading to an increased risk of caries and gingivitis due to poor oral hygiene. A change in patient management may be necessary to ensure optimal care.

Abstract Background Grade group (GG) 4 prostate cancer (PC) is considered a single entity; however, there are questions regarding prognostic heterogeneity. This study assessed the prognostic differences among various Gleason scores (GSs) classified as GG 4 PC on biopsy before radical prostatectomy (RP). Methods We conducted a multicenter retrospective study, and a total of 1791 patients (GS 3 + 5: 190; GS 4 + 4: 1557; and GS 5 + 3: 44) with biopsy GG 4 were included for analysis. Biochemical recurrence (BCR)-free survival, cancer-specific survival, and overall survival were analyzed using the Kaplan–Meier method and the log-rank test. Logistic regression analysis was performed to identify factors associated with high-risk surgical pathologic features. Cox regression models were used to analyze time-dependent oncologic endpoints. Results Over a median follow-up of 75 months, 750 patients (41.9%) experienced BCR, 146 (8.2%) died of any causes, and 57 (3.2%) died of PC. Biopsy GS 5 + 3 was associated with significantly higher rates of GS upgrading in RP specimens than GS 3 + 5 and GS 4 + 4. On multivariable analysis adjusted for clinicopathologic features, different GSs within GG 4 were significantly associated with BCR (p = 0.03) but not PC-specific or all-cause mortality. Study limitations include the lack of central pathological specimen evaluation. Conclusions Patients with GG 4 at biopsy exhibited some limited biological and clinical heterogeneity. Specifically, GS 5 + 3 had an increased risk of GS upgrading. This can help individualize patients’ counseling and encourage further study to refine biopsy specimen-based GG classification.
