A modified dentin infection model with Fluorescent Lipopolysaccharide and LPS sampling technique to compare XP‐Endo finisher and passive ultrasonic irrigation

alexandrossfakianakis shared this article with you from Inoreader A modified dentin infection model with Fluorescent Lipopolysaccharide and LPS sampling technique to compare XP‐Endo finisher and passive ultrasonic irrigation via International Endodontic Journal Abstract Aim The LPS-dentine-infection models and sampling techniques frequently used to evaluate LPS disinfection have limitations. In this study, a lipopolysaccharides-dentine-infection (LPS-dentine-infection) model was devised using fluorescent conjugate LPS. Secondly, a sampling technique using cryogenic grinding for intraradicular LPS analysis was evaluated. Thirdly, the effectiveness of the XP-endo Finisher (XP-EF) was compared with passive ultrasonic irrigation (PUI) in removing LPS from root canal system. Methodology Sixty-nine mandibular premolars was submitted to dentine pretreatment and inoculated with fluorescent LPS conjugate (Alexa Fluor® 594). Twenty-three teeth were analysed under confocal laser scanning microscopy (CLSM) to validate this modified LPS-dentine-infection model. Forty-six teeth were randomly divided into two experimental groups: XP-EF (n = 23) and PUI (n = 23). All teeth were instrumented with XP-endo shaper (XPS; FKG Dentaire, La Chaux-de-Fonds, Switzerland) and 2.5% NaOCl. The root canals were sampled with paper points before (s1) and after (s2) instrumentation and after supplemental treatment (s3) with XP-EF and PUI. After s3, all roots were cryogenically ground for intraradicular LPS analysis (s4). Limulus amebocyte lysate (LAL) assay was used for LPS quantification. The Friedman test was used for differences in LPS among four timepoints (s1, s2, s3, and s4). Dunn's test was used for pairwise testing of timepoints. The significance level wa s set at 5% (P < .05). Results Fluorescent LPS conjugate was detected in 100% of the samples under CLSM with a penetration depth of approximately 400 μm into dentine. Chemo-mechanical preparation using XPS files significantly reduced LPS levels (p < .05). Both the XPS and PUI improved the LPS disinfection (p < .05), with no difference between them (p > .05). LPS was recovered from all samples after cryogenic grinding. The residual amount of LPS detected using the cryogenically sampling technique at s4 was approximately 3 times greater than with the paper point sampling technique at s3. Conclusion This study established a modified LPS-dentine-infection model using fluorescent conjugate LPS, and validated a LPS sampling technique for using cryopulverization intraradicular LPS analysis. Moreover, both the XP-EF and PUI further improved LPS disinfection from the root canals, and the innovative XP-EF was as effective as PUI. View on Web

Incidence, risk factors, outcomes, and clinical management of BK viremia in the modern era of kidney transplantation

alexandrossfakianakis shared this article with you from Inoreader Incidence, risk factors, outcomes, and clinical management of BK viremia in the modern era of kidney transplantation via Transplant Infectious Disease ABSTRACT Background : BK viremia is endemic among kidney transplant recipients (KTR). Incidence, risk factors, outcomes, and clinical management of detectable versus high BK viremia have not been considered previously in KTR in the modern era. Methods : This observational study examined KTR transplanted between January 1, 2009 and December 31, 2016. Any BK viral load in the serum constituted detectable BK viremia and ≥103 copies/mL constituted high viremia. Results : Among 1,193 KTR, the cumulative probability of developing detectable and high BK viremia within two years post-transplant were 27.8% and 19.6%, respectively. Significant risk factors for detectable BK viremia included recipient age (HR 1.02 [95% CI: 1.01, 1.03]) and donor age (HR 1.01 [95% CI: 1.00, 1.02]). Recipient age also predicted high BK viremia (HR 1.02 [95% CI: 1.01, 1.03]), whereas White race (HR 0.70 [95% CI: 0.52, 0.95]), non-depleting induction therapy (HR 0.61 [95% CI: 0.42, 0.89]), and delayed graft function (HR 0.61 [95% CI: 0.42, 0.88]) were protective. Mean estimated glomerular filtration rates were 4.28 mL/min/1.72 m2 (95% CI: 2.71, 5.84) lower with detectable BK viremia. Although low viral load was usually not acted upon at first presentation, anti-proliferative dose reductions were the most common initial management. Conclusion : BK viremia remains a common early complication in a modern cohort of KTR. These findings highlight the benefit of early BKV monitoring in addition to intensive clinical management. Clinical responses beyond first positive BK viremia tests, and their implications for graft outcomes, merit further investigation. This article is protected by copyright.

Case volume regionalization and volume‐based outcome differences in cutaneous head and neck melanoma

alexandrossfakianakis shared this article with you from Inoreader Case volume regionalization and volume‐based outcome differences in cutaneous head and neck melanoma via Head & Neck Abstract Background Hospital volume has emerged as a prognostic factor in oncology but is not currently known whether volume is associated with improved outcomes for cutaneous head and neck (HN) melanoma. Methods A total of 556 079 cutaneous melanoma cases reported by the 2004–2016 National Cancer Database were separated into two cohorts (HN and non-HN) and facilities within each cohort were classified by case volume. Analysis employed chi-square, analysis of variance, Kaplan–Meier, and Cox proportional hazards models. Results Only 41 facilities (3.1% of 1326) treating HN melanoma and 50 facilities (3.7% of 1344) treating non-HN melanoma were classified as high-volume facilities (HVFs). The estimated 5-year overall survival (OS) was 62.7% (standard error [SE]: 0.4%) for patients with HN at low-volume facilities (LVFs), 69.3% (SE: 0.4%) at IVFs, and 71.8% (SE 0.4%) at HVFs (p < 0.001). Differences in OS remained significant between HVFs versus LVFs after adjusting for confounders. Conclusion Volume is independently associated with OS and improved surgical outcomes for HN melanoma.

Menopausal hormone therapy and subclinical cardiovascular disease in women with and without HIV

alexandrossfakianakis shared this article with you from Inoreader Menopausal hormone therapy and subclinical cardiovascular disease in women with and without HIV via Clinical Infectious Diseases Advance Access Abstract Background Estrogen-based hormone therapy (HT) may have beneficial cardiovascular effects when initiated in early menopause. This has not been examined in women with HIV who have heightened immune activation and cardiovascular risks. Methods Among 609 post-menopausal women (1,234 person-visits) in the Women's Interagency HIV Study, we examined the relationship of ever HT use (oral, patch, or vaginal) with subclinical atherosclerosis – carotid artery intima-media thickness (CIMT), distensibility, and plaque assessed via repeated B-mode ultrasound imaging (2004-2013). We also examined associations of HT with cross-sectional biomarkers of immune activation and D-dimer. Statistical models were adjusted for sociodemographic, behavioral, and cardiometabolic factors. Results Women (mean age = 51, 80% HIV+) who ever used HT at baseline were older, and more likely to be non-Hispanic White and report higher income, than never users. Women who ever used HT had 43% lower prevalence of plaque (prevalence ratio = 0.57; 95% CI = [0.40, 0.80]; p < 0.01), 2.51 µm less progression of CIMT per year (95% CI = [-4.60, -0.41]; p = 0.02), and marginally lower incidence of plaque over ∼7 years (risk ratio = 0.38; 95% CI = [0.14, 1.03]; p = 0.06), compared with never users, adjusting for covariates; ever HT use was not associated with distensibility. These findings were similar for women with and without HIV. Ever HT use was associated with lower serum D-dimer, but not with biomarkers of immune activation after covariate adjustment. Conclusions HT may confer a subclinical cardiovascular benefit in women with HIV. These results begin to fill a knowledge gap in menopausal care for women with HIV, in whom uptake of HT is very low.

Newborn body composition and child cardiovascular risk markers: a prospective multi-ethnic Asian cohort study

alexandrossfakianakis shared this article with you from Inoreader Newborn body composition and child cardiovascular risk markers: a prospective multi-ethnic Asian cohort study via International Journal of Epidemiology - Advance Access Abstract Background Early epidemiological studies have associated low birthweight with increased cardiovascular risk. We aimed to examine whether the fat and fat-free components of birthweight have differing relationships with childhood cardiovascular risk markers. Methods In the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort, air displacement plethysmography was conducted within 24 h after delivery in 290 naturally conceived singletons. We investigated associations of newborn cohort-specific standardized z-score of fat mass, fat-free mass, body fat percentage and birthweight on child (at 6 years of age) carotid intima-media thickness, pulse wave velocity, blood pressure, prehypertension/hypertension (>110/70 mmHg) and standardized systolic and diastolic blood pressure (SBP and DBP) trajectories (at 3–6 years of age), taking account of maternal education, height, tobacco exposure, parity, ethnicity, child� �s sex, gestational age, age at follow-up, and other maternal factors. Results Clear inverse associations were seen for blood pressure with z-score of fat mass [SBP, β (95% CI): −1.31 mmHg (−2.57, −0.06); DBP: −0.79 mmHg (−1.74, 0.15)] and body fat percentage [SBP: −1.46 mmHg (−2.73, −0.19); DBP: −0.80 mmHg (−1.75, 0.16)], but not with fat-free mass [SBP: 0.27 mmHg (−1.29, 1.83)]; DBP: −0.14 mmHg (−1.30, 1.03)]. Being in the lowest tertile of fat mass or body fat percentage was associated with higher blood pressure trajectories and prehypertension/hypertension risk [OR (95% CI), fat mass: 4.23 (1.41, 12.68); body fat percentage: 3.22 (1.09, 9.53)] without concomitantly higher overweight/obesity risk. Conclusions At birth, low adiposity was associated with increased childhood blood pressure. Low newborn adiposity might serve as a marker of poor fetal growth or suboptimal intrauterine conditions associated with hypertension risk later in life. View on Web

Impact of a prognostic model for overall survival on the decision‐making process in a head and neck cancer multidisciplinary consultation meeting

alexandrossfakianakis shared this article with you from Inoreader Impact of a prognostic model for overall survival on the decision‐making process in a head and neck cancer multidisciplinary consultation meeting via Head & Neck Abstract Background Multidisciplinary decision-making in head and neck cancer care is complex and requires a tradeoff between prolonging survival and optimizing quality of life. To support prognostication and decision-making in head and neck cancer care, an individualized prognostic model for overall survival (OncologIQ) is available. Methods By quantitative and qualitative research we have studied user value of OncologIQ and its impact on the decision-making process in a multidisciplinary consultation meeting. Results Healthcare professionals experienced added value upon using prognostic estimates of survival from OncologIQ in half (47.5%) of the measurements. Significant impact on the decision making process was seen when OncologIQ was used for older patients, patients having a WHO performance score ≥ 2, or high tumor stage. Conclusions The prognostic model OncologIQ enables patient-centered decision-making in a multidisciplinary consultation meeting and was mostly valued in complex patients. View on Web

Long-term wellbeing and neurocognitive functioning of diffuse low-grade glioma patients and their caregivers: a longitudinal study spanning two decades

alexandrossfakianakis shared this article with you from Inoreader Long-term wellbeing and neurocognitive functioning of diffuse low-grade glioma patients and their caregivers: a longitudinal study spanning two decades via Neuro-Oncology Advance Access Abstract Background While patients with diffuse low-grade glioma (LGG) often survive for years, there is a risk of tumour progression which may impact on patients' long-term health-related quality of life (HRQOL) and neurocognitive functioning (NCF). We present a follow-up of LGG patients and their informal caregivers (T3) who took part in our previous HRQOL investigations (T1, M=7 and T2 M=13 years after diagnosis). Methods Participants completed HRQOL (SF-36; EORTC-BN20), fatigue (Checklist Individual Strength (CIS)), and depression (Center for Epidemiological Studies-Depression (CES-D)) questionnaires and underwent NCF assessments. T3 scores were compared with matched controls. Change over time (T1-T2-T3) on group and participant level were assessed. Where available, histology of the initial tumour was revised and immunohistochemical staining for IDH1 R 132H mutant protein was performed. Results Thirty patients and nineteen caregivers participated. Of N=11 with tissue available, 3 patients had confirmed diffuse LGG. At T3, patients (M=26 years after diagnosis) had HRQOL and NCF similar to, or better than controls, yet 23.3% and 53.3% scored above the cut-off for depression (≥16 CES-D) and fatigue (≥35 CIS), respectively. Caregivers' HRQOL was similar to controls, but reported high rates of fatigue (63.2%). Over time, patients' mental health improved (p<.05). Minimal detectable change in HRQOL over time was observed in individual patients (30% improvement; 23.3% decline; 20% both improvement and decline) with 23.3% remaining stable. NCF remained stable or improved in 82.8% of patients. Conclusions While HRQOL and NCF do not appear greatly impacted during long-term survivorship in LGG, d epressive symptoms and fatigue are persistent. View on Web

Facial nerve palsy: Narrative review on the importance of the eye and its assessment

alexandrossfakianakis shared this article with you from Inoreader Facial nerve palsy: Narrative review on the importance of the eye and its assessment via Head & Neck Abstract New solutions are emerging that address specific facial regions in facial nerve palsy (FNP). However the most dreaded consequence of FNP is paralytic lagophthalmos threatening the eye. A way to prioritize these regions is thus required. A review of the literature is conduced to capture the current concepts in evaluating FNP. Overall, patients are assessed from three perspectives: from the clinician's perspective using validated clinician-based grading instruments, from patient's perspective based on FNP-specific patient-reported outcome measures, and from the perspective of the layperson. The existing tools however provide limited information regarding the relative importance of different regions of the face. The eye appears to be an area of great concern for the patient where most surgical therapies are directed at. Addressing ocular problems in FNP carry a high priority but this is not clearly reflected by the standard systems. View on Web

STATIN USE MAY BE ASSOCIATED WITH A LOWER RISK OF INVASIVE ASPERGILLOSIS IN LUNG TRANSPLANT RECIPIENTS

alexandrossfakianakis shared this article with you from Inoreader STATIN USE MAY BE ASSOCIATED WITH A LOWER RISK OF INVASIVE ASPERGILLOSIS IN LUNG TRANSPLANT RECIPIENTS via Clinical Infectious Diseases Advance Access Abstract Background Statins are competitive inhibitors of HMG-CoA reductase that catalyses HMG-CoA conversion to mevalonate, a process involved in synthesizing cholesterol in humans and ergosterol in fungi. The effect of statin use on the risk of development of invasive aspergillosis (IA) in lung transplant recipients (LTRs) is not well documented. Methods This retrospective study included LTRs from 2010 to 2017 who were followed for one-year post-transplant. Proven or probable IA was diagnosed as per ISHLT criteria. We performed a multivariable Cox proportional hazards model of the association between IA and statin use (minimum of two weeks duration prior to IA), adjusting for other known IA risk factors. Results We identified 785 LTRs, 44% female, mean age 53 years old, the most common underlying disease being pulmonary fibrosis (23.8%). 451 LTRs (57%) received statins post-transplant, atorvastatin was the most commonly used statin (68%). The mean duration of statins post-transplant was 347 days (IQR: 305 to 346). 55 (7%) LTRs developed IA in the first-year post-transplant. Out of these 55 LTRs, 9 (16.3%) had received statin before developing IA. In multivariable analysis, statin use was independently associated with a lower risk of IA (p = 0.002, SHR 0.30, CI 95% 0.14-0.64). Statin use was also associated with a lower incidence of post-transplant Aspergillus colonization, 114 (34%) in the no statin group vs. 123 (27%) in the statin group (p = 0.038). Conclusions The use of statin for a minimum of two weeks during the first-year post-transplant was associated with a 70% risk reduction of IA in LTRs. View on Web
