stage 1 hypertension by the 2017 american college of cardiology american heart association hypertension guidelines and risk of cardiovascular disease events systematic review meta analysis and estimation of population Etiologic Fraction of prospectiv
Journal of Hypertension, 2020Co-Authors: Minghui Han, Qing Chen, Leilei Liu, Yongcheng Ren, Yang Zhao, Dechen Liu, Dongdong Zhang, Feiyan Liu, Xu Chen, Cheng ChengAbstract:Background Epidemiological studies reported an inconsistent association between stage 1 hypertension (SBP 130-139 mmHg or DBP 80-89 mmHg) defined by the 2017 American College of Cardiology/American Heart Association hypertension guidelines and cardiovascular disease (CVD) events. In addition, the proportion of CVD events that could be prevented with effective control of stage 1 hypertension is unknown. Objectives To assess the association between stage 1 hypertension and CVD events and estimate the population Etiologic Fraction. Methods PubMed, Embase, and Web of Science databases were searched from 1 January 2017 to 22 September 2019. Normal BP was considered SBP less than 120 mmHg and DBP less than 80 mmHg. Hazard ratios and 95% confidence intervals (95% CIs) were pooled by using a random-effects model. Results We included 11 articles (16 studies including 3 212 447 participants and 65 945 events) in the analysis. Risk of CVD events was increased with stage 1 hypertension versus normal BP (hazard ratio 1.38, 95% CI 1.28-1.49). On subgroup analyses, stage 1 hypertension was associated with coronary heart disease (CHD) (hazard ratio 1.30, 95% CI 1.20-1.41), stroke (1.39, 1.27-1.52), CVD morbidity (1.42, 1.32-1.53), and CVD mortality (1.34, 1.05-1.71). The population Etiologic Fraction for the association of CVD events, CHD, stroke, CVD morbidity, and CVD mortality with stage 1 hypertension was 12.90, 10.48, 12.71, 14.03, and 11.69%, respectively. Conclusion Stage 1 hypertension is associated with CVD events, CVD morbidity, CVD mortality, CHD, and stroke. Effective control of stage 1 hypertension could prevent more than 10% of CVD events.

Low Etiologic Fraction for human papillomavirus in larynx squamous cell carcinoma.
Oral oncology, 2016Co-Authors: Miren Taberna, Bo Jiang, Robert K. L. Pickard, Paul Kreinbrink, C. Resteghini, Benjamin Swanson, Wiehong Xiao, M. Mena, E. Chio, Maura L. GillisonAbstract:Abstract Background Human Papillomavirus (HPV) is a cause of oropharyngeal squamous cell carcinoma (OPSCC), but its pathogenic role in larynx squamous cell carcinoma (LSCC) remains unclear. Material and methods A single-institutional, retrospective case-series was performed to estimate the Etiological Fraction (EF) for HPV in LSCC. Eligible cases included 436 consecutive cases of LSCC diagnosed (2005–2014) at The Ohio State University Medical Center. HPV DNA presence was detected by consensus primer PCR (Inno-LiPa) and HPV type-specific qPCR. HPV E6/E7 mRNA expression was detected by type-specific qRT-PCR. Tumor p16 expression was evaluated by immunohistochemistry (IHC). Results HPV DNA was detected by Inno-LiPa in 54 of 404 (13.4%, 95% CI 10.2–17.1) evaluable samples but was confirmed by HPV type-specific qPCR in only 14 (3.5%, 95% CI 1.9–5.7). Only 7 of 404 (1.7%, 95% CI 0.7–3.5) LSCC were positive for HPV E6/E7 mRNA expression, including HPV16 (n = 4) and 1 each for 11, 26 and 33. In the HPV11-positive tumor, Sanger sequencing discovered 6 nucleotide mutations in the upstream regulation region, E6 and E7. Of 404 LSCC, 18 had strong and diffuse p16 expression. In comparison to a gold standard of HPV E6/E7 mRNA expression, p16 expression had a sensitivity of 71.4% (95% CI 29.0–96.3), specificity of 96.7% (95% CI 94.5–98.3), positive-predictive-value (PPV) of 27.8% (95% CI 9.7–53.5) and negative-predictive-value of 99.5% (95% CI 98.1–99.9). Conclusion The EF for HPV in LSCC is low (1.7%) in a geographic region with high EF for OPSCC. Low-risk HPV may rarely cause LSCC. Finally, p16 expression has poor PPV for HPV in LSCC.

Low Etiologic Fraction for high-risk human papillomavirus in oral cavity squamous cell carcinomas
Oral oncology, 2012Co-Authors: Mark W. Lingen, Weihong Xiao, Alessandra C. Schmitt, Bo Jiang, Robert K. L. Pickard, Paul Kreinbrink, Bayardo Perez-ordonez, Richard C.k. Jordan, Maura L. GillisonAbstract:Summary Background Human papillomavirus (HPV) is a cause of oropharyngeal cancer, but a role for HPV in the etiology of oral cavity squamous cell carcinomas (OCSCC) remains uncertain. Methods We sought to estimate the Etiologic Fraction for HPV among consecutive, incident OCSCC diagnosed from 2005 to 2011 at four North American hospitals. DNA and RNA purified from paraffin-embedded tumors were considered evaluable if positive for DNA and mRNA control genes by quantitative PCR. Fifteen high-risk (HR) HPV types were detected in tumors by consensus PCR followed by type-specific HR-HPV E6/7 oncogene expression by quantitative reverse-transcriptase PCR. P16 expression was evaluated by immunohistochemistry (IHC). A study of 400 cases allowed for precision to estimate an Etiologic Fraction of as low as 0% (97.5% confidence interval, 0–0.92%). Results Of 409 evaluable OCSCC, 24 (5.9%, 95%CI 3.6–8.2) were HR-HPV E6/7 expression positive; 3.7% (95%CI 1.8–5.5) for HPV16 and 2.2% (95%CI 0.8–3.6) for other HR-HPV types. HPV-positive tumors arose from throughout the oral cavity (floor of mouth [ n = 9], anterior tongue [6], alveolar process [4], hard palate [3], gingiva [1] and lip [1]) and were significantly associated with male gender, small tumor stage, poor tumor differentiation, and basaloid histopathology. P16 IHC had very good-to-excellent sensitivity (79.2%, 95%CI 57.9–92.9), specificity (93.0%, 95%CI 90.0–95.3), and negative-predictive value (98.6%, 95%CI 96.8–99.6), but poor positive-predictive value (41.3%, 95%CI 27.0–56.8) for HR-HPV E6/7 expression in OCSCC. Conclusion The Etiologic Fraction for HR-HPV in OCSCC was 5.9%. p16 IHC had poor positive predictive value for detection of HPV in these cancers.

systematic review and meta analysis estimating association of cysticercosis and neurocysticercosis with epilepsy
PLOS Neglected Tropical Diseases, 2017Co-Authors: Gabrielle Debacq, Luz M Moyano, Hector H Garcia, Farid Boumediene, Benoit Marin, Edgard Brice Ngoungou, Pierremarie PreuxAbstract:Background We reviewed studies that analyzed cysticercosis (CC), neurocysticercosis (NCC) and epilepsy across Latin America, Asia and Sub-Saharan Africa, to estimate the odds ratio and Etiologic Fraction of epilepsy due to CC in tropical regions. Methodology We conducted a systematic review of the literature on cysticercosis and epilepsy in the tropics, collecting data from case-control and cross-sectional studies. Exposure criteria for CC included one or more of the following: serum ELISA or EITB positivity, presence of subcutaneous cysts (both not verified and unverified by histology), histology consistent with calcified cysts, and brain CT scan consistent with NCC. A common odds-ratio was then estimated using meta-analysis. Principal findings 37 studies from 23 countries were included (n = 24,646 subjects, 14,934 with epilepsy and 9,712 without epilepsy). Of these, 29 were case-control (14 matched). The association between CC and epilepsy was significant in 19 scientific articles. Odds ratios ranged from 0.2 to 25.4 (a posteriori power 4.5–100%) and the common odds ratio was 2.7 (95% CI 2.1–3.6, p <0.001). Three subgroup analyses performed gave odds ratios as: 2.2 (EITB-based studies), 3.2 (CT-based studies), 1.9 (neurologist-confirmed epilepsy; door-to-door survey and at least one matched control per case). Etiologic Fraction was estimated to be 63% in the exposed group among the population. Significance Despite differences in findings, this meta-analysis suggests that cysticercosis is a significant contributor to late-onset epilepsy in tropical regions around the world, and its impact may vary depending on transmission intensity.
