ABSTRACT

OBJECTIVES: The purpose of this in vitro study was to investigate the effects of various surface treatment methods on the shear bond strength of self-adhesive resin cement to polymer-infiltrated materials.

MATERIALS AND METHODS: One hundred twenty-eight polymer-infiltrated specimens (n = 32) for four different computer aided design-computer-aided manufacturing (CAD-CAM) materials, polyether ether ketone (PEEK) (PE), polyether ketone ketone (PEKK) (PK), composite resin nanoceramic (Cerasmart) (CS), and polymer-infiltrated ceramic network (PICN) (VITA ENAMIC) (VE) were milled from CAD-CAM blocks. They were divided into two groups (n = 16) in terms of surface treatments: airborne-particle abraded (AA) or silica-coated (SC) and two subgroups (n = 8) according to adhesive application or no adhesive. The surface roughness, contact angle, and shear bond strength (SBS) values of specimens were measured. Data were analyzed with Shapiro-Wilk test, the generalized linear models’ method, and Bonferroni corrected t test (α ˂ 0.05).

RESULTS: No statistically significant differences were found between the groups in terms of surface roughness and SBS values (P > 0.05). A statistically significant effect of the main adhesive interaction on the bond strength was found independent of the material and surface treatments (P < 0.001). While the average bond strength of the non-adhesive was 4.9 MPa, the average of the adhesive applied was 9.1 MPa. On the other hand, there is a statistically significant difference between the means of the contact angle values (P ˂ 0.001). While the highest mean contact angle value was 117.1 ± 14.8° obtained from the non-adhesive PK in the AA group, the lowest mean contact angle value 22.6 ± 4.3° was obtained from the VE without adhesive in the SC group.

CONCLUSIONS: Roughness and SBS values were similar between groups after surface treatments. Adhesive application increased the SBS values. Surface treatments were found to have an effect on the contact angle.

CLINICAL RELEVANCE: Since the AA and SC surface treatments used in the study show similar bond strength values, the Cojet system, which is more practical and easier to use, can be preferred as an alternative to AA after restoration production with CAD-CAM as a chairside.

ABSTRACT

BACKGROUND: This study compared survival between patients who had medullary thyroid cancer (MTC) treated with surgery alone and patients who underwent surgery and radiation (SRT).

METHODS: Patients from the National Cancer Database (NCDB) with a diagnosis of stage 3 or 4 MTC, lymph node disease, and no distant metastases between 2008 and 2016 were studied. Kaplan-Meier analyses and log-rank statistics were used to estimate and compare overall survival between patients treated with surgery alone and those treated with SRT. Mutlivariable Cox proportional hazards models and propensity-matching were used to adjust for confounding and selection bias.

RESULTS: Among 1370 patients, 1112 (81%) received surgery alone, and 258 (19%) received SRT. The hazard ratio for mortality in the SRT group was 1.784 (95% confidence interval [CI] 1.313-2.43) after multivariable adjustment for confounding variables. Furthermore, SRT remained associated with a higher mortality rate (p < 0.008) after propensity-matching in an effort to adjust for selection bias.

CONCLUSIONS: This analysis of NCDB patients showed that SRT is associated with a significantly higher mortality rate among patients treated for stage 3 or 4 IV MTC with positive lymph node disease. Although this observation can be attributed to unmeasured confounders or selection bias, the cause for the profound survival differences deserves prospective evaluation, especially as adjuvant therapies for this disease continue to evolve.

ABSTRACT

The human grading system is currently applied to canine meningioma, although it has not been validated in dogs. The present study focused on standardizing the human grading system applied to canine meningioma. Four veterinary neuropathologists graded 186 canine meningiomas as follows: grade I tumor, with <4 mitoses/2.37 mm² ; grade II tumor, with ≥4 mitoses/2.37 mm² , brain invasion or at least 3 of the following criteria: sheeting architecture, hypercellularity, small cells, macronucleoli, necrosis; grade III tumor, with ≥20 mitoses/2.37 mm² or anaplasia. Slides with grading disagreement were reviewed to define a consensus diagnosis and to assess reproducible criteria. Concordance between histologic grade and the consensus diagnosis, as well as intra- and inter-observer agreements for each criterion, were statistically analyzed. Concordance between histologic grade and consensus diagnosis ranged from 59% to 100%, with lower concordance for grade I and II tumors. The lowest inter-observer agreement was recorded for macronucleoli, small cells, hypercellularity and sheeting architecture. Tumor invasion and necrosis displayed fair agreement, while moderate agreement was reached for mitotic grade and anaplasia. The following recommendations were issued to improve reproducibility of canine meningioma grading: 1. Assess mitotic grade in consecutive HPFs within the most mitotically active area; 2. Define invasion as neoplastic protrusions within central nervous tissue without pial lining; 3. Report spontaneous necrosis; 4. Report prominent nucleoli when visible at 100x; 5. Report pattern loss when visible at 100x in > 50% of the tumor; 6. Report necrosis, small cells, hypercellularity and macronucleoli, even when focal; 7. Report anaplasia if multifocal.

ABSTRACT

BACKGROUND: Epidermal growth factor (EGF) may promote wound healing and decrease laser-induced postinflammatory hyperpigmentation (PIH).

OBJECTIVES: To evaluate the effectiveness of an EGF-containing cream on PIH, post-laser erythema, and transepidermal water loss (TEWL) after 1,064-nm Q-Switched Nd: YAG laser treatment of Hori’s nevus.

METHODS: This is a split-face, double-blinded, randomized, controlled study conducted in 30 subjects with bilateral Hori’s nevus. After laser treatment, participants were randomized to apply EGF cream on one facial side and placebo on the other side for 8 weeks. The incidence and intensity of PIH were assessed by photographs and melanin indexes (MIs) ratio at baseline, Week 2, Week 4, and Week 8. Post-laser erythema and TEWL were measured at baseline, Day 1, Day 3, and Day 7. Side effects and patient satisfaction score were evaluated.

RESULTS: The incidence of PIH was 26.7% in EGF group compared to 20% in placebo. The intensity of PIH was 0.057 (0.033-0.086) and 0.045 (0.027-0.076) in EGF and placebo group, respectively. There was no significant difference in both incidence (p = 0.5) and intensity of PIH (p = 0.145). Post-laser erythema was not statistically different between groups. EGF could alleviate TEWL better than placebo but without statistical significance. Patient satisfaction score was significantly higher in EGF group compared to placebo (p < 0.001).

CONCLUSIONS: The EGF-containing cream could not prevent PIH. It may reduce laser-induced skin barrier damage. Future studies in more subjects are needed.

ABSTRACT

OBJECTIVES: Vascular access site complications increase morbidity and mortality in transcatheter aortic valve replacement (TAVR).

BACKGROUND: Medtronic’s EnVeo PRO® low-profile sheath concept and Edwards’ expandable eSheath® aim to lower vascular trauma and access site complications. This study aims to compare Valve Academic Research Consortium (VARC)-3 defined access-related vascular complications using the two different transcatheter heart valve (THV) delivery concepts.

METHODS: We performed a retrospective, propensity-matched study to compare access site vascular complications in 756 consecutive patients who underwent a transfemoral TAVR using a Medtronic Evolut-R®/Evolut-PRO® or an Edwards Sapien3®/Sapien3ultra® THV.

RESULTS: Propensity score matching resulted in 275 patient pairs. The primary endpoint of major VARC-3 vascular complication was 7.6% in the Medtronic group and 12.7% in the Edwards group (p = 0.066). Minor VARC-3 vascular complications were 9.1% and 8%, respectively (p = 0.76). VARC-3 bleeding complications (8.4% vs. 12.7%, p = 0.129) length of hospital stay (7.6 + 5.4 vs. 7.5 + 3.7 days, p = 0.783) and in-hospital mortality (1.1% vs. 0.4%, p = 0.624) were comparable between both groups.

CONCLUSIONS: In a propensity-matched TAVR population, patients treated with the integrated sheath showed a trend towards fewer major vascular complications than patients treated with an expandable sheath, however, the difference was not statistically significant.

ABSTRACT

OBJECTIVE: The aim of the research was to determine the effect of education given to the women with hearing impairments on the behaviours of Pap smear test.

METHODS: This study was a controlled trial study with longitudinal design. The sample consisted of 156 women (intervention = 78, control = 78) who registered in hearing-impaired associations in Izmir, Turkey. The education about cervical cancer and Pap smear test was given to intervention group with face-to-face interviews by using Turkish sign language. Three months later, the women were contacted and asked whether they have had a Pap smear test, and the total knowledge score of intervention groups was evaluated.

RESULTS: There was not a statistically significant difference between the mean total score of knowledge about cervical cancer and Pap smear test in intervention (0.6 ± 1.6) and control (1.1 ± 1.9) groups. After 3 months, having a Pap smear test was found to be statistically significantly higher between groups (intervention = 29.5%, control = %1.2), and the mean cervical cancer and Pap smear knowledge score of the intervention group (9.2 ± 1.4) was found to be statistically significantly higher than the score before education (0.6 ± 1.6).

CONCLUSION: Education of cervical cancer and Pap smear test increased knowledge level and behaviour of Pap smear test of the women.

ABSTRACT

Magnetic resonance imaging (MRI) is a valuable imaging modality for the assessment of both cardiac and non-cardiac structures. With a growing population of patients with cardiovascular implantable electronic devices (CIEDs), 50%-75% of these patients will need an MRI. MRI-conditional CIEDs have demonstrated safety of MRI scanning with such devices, yet non-conditional devices such as hybrid CIEDs which have generator and lead brand mismatch may pose a safety risk. In this retrospective study, we examined the outcomes of patients with hybrid CIEDs undergoing MRI compared to those patients with non-hybrid CIEDs. A total of 349 patients were included, of which 24 patients (7%) had hybrid CIEDs. The primary endpoint was the safety of MRI for patients with hybrid CIEDs as compared to those with non-hybrid devices, measured by the rate of adverse events, including death, lead or generator failure needing immediate replacement, loss of capture, new onset arrhythmia, or power-on reset. Secondary endpoints consisted of pre- and post-MRI changes of decreased P-wave or R-wave sensing by ≥50%, changes in pacing lead impedance by ≥50 ohms, increase in pacing thresholds by ≥ 0.5 V at 0.4 ms, and decreasing battery voltage of ≥ 0.04 V. The primary endpoint of any adverse reaction was present in 1 (4.2%) patient with a hybrid device, and consistent of atrial tachyarrhythmia, and in 10 (3.1%) patients with a non-hybrid device, and consisted of self-limited atrial and non-sustained ventricular arrhythmias; this was not statistically significant. No significant differences were found in the secondary endpoints. This study demonstrates that MRI in patients with hybrid CIEDs does not result in increased patient risk or significant device changes when compared to those patients who underwent MRI with non-hybrid CIEDs.

ABSTRACT

AIM: To evaluate the prognostic utility of red blood cell distribution width (RDW) and maximum left ventricular wall thickness (MLVWT) in patients with hypertrophic cardiomyopathy (HCM).

PATIENTS AND METHODS: This study is a retrospective cohort analysis. Patients diagnosed with HCM at the First Affiliated Hospital of Sun Yat-sen University from March 2014 to March 2019 were included. HCM patients were stratified into two groups based on the occurrence of major adverse cardiac events (MACE). Receiver operating characteristic (ROC) curves were then constructed and Cox regression models were employed to gauge the prognostic relevance of RDW and MLVWT for HCM patients. Kaplan-Meier analysis evaluated the survival and MACE-free rate in patients with different level of RDW and MLVWT.

RESULTS: A total of 300 patients with HCM were enrolled in this study and followed up for 40.56±18.33 months. Among them, 117 MACE (39.00%), 40 all-cause deaths (13.33%), and 29 cardiovascular deaths (9.67%). The level of RDW, MLVWT, creatinine (Cr), and B-type pro-brain natriuretic peptide (NT-ProBNP) were statistically different between the MACE group and non-MACE group (P < .05). Multivariate analysis showed that after adjusting for confounding factors, RDW and MLVWT were independent predictors of all-cause mortality and MACE in HCM patients. ROC showed that RDW > .13 and MLVWT > 23 mm are the cut-off value to predict all-cause mortality and MACE. The area under the ROC curve AUC of the combination predicting the occurrence of all-cause mortality and MACE are .823 and .820, respectively. Kaplan-Meier analysis showed that the survival rate and MACE-free survival rate of group 1 (RDW≦.13 and MLVWT≦23 mm) were significantly higher than group 2 (RDW > .13 or MLVWT > 23 mm), and group 3 (RDW > .13 and MLVWT > 23 mm) (P = .000).

CONCLUSION: We determined that increased RDW and MLVWT was independently associated with MACE incidence and risk of mortality in HCM patients. Combined evaluation of RDW and MLVWT yielded a more accurate predictive model of HCM patient outcomes relative to the use of either of these metrics in isolation. Our research can provide a theoretical basis in the occurrence of MACE for the high-risk HCM and intervene them properly and timely.

ABSTRACT

We investigated the potential relationship between receipt of electroconvulsive therapy (ECT) and development of amyotrophic lateral sclerosis (ALS). We conducted a cohort study using a sample of more than one million beneficiaries enrolled in the U.S. Medicare health insurance program from 1997 to 2017. Using time-varying proportional hazard modeling, we compared ALS occurrence among patients diagnosed with psychiatric conditions who received ECT to ALS occurrence among patients diagnosed with psychiatric conditions but who did not receive ECT. We observed moderately increased, but imprecise, hazard ratios (HR) for ALS following ECT (HR = 1.39, 95% confidence interval [CI]: 0.69-2.80). A statistically significant increase in the HR of ALS was observed among those who received more than 10 ECT treatments (>10 treatments, HR = 2.24, 95% CI: 1.00-5.01), compared to those receiving no ECT, with an even stronger association observed among subjects older than 65 years (HR = 3.03, 95% CI: 1.13-8.10). No monotonic exposure-response relationship was detected in categorical analyses. Our results provide weak support for the hypothesis that receipt of ECT increases the risk of developing ALS. Additional studies in larger populations, or in populations where ECT is more common, will be needed to refute or confirm an association between receipt of ECT and subsequent development of ALS. © 2022 Bioelectromagnetics Society.

ABSTRACT

BACKGROUND: Acute myocardial infarction (AMI) is the main cause of death and disability in cardiovascular and cerebrovascular diseases. Both the Global Registry of Acute Coronary Events (Grace) score and high-sensitivity C-reactive protein (hs-CRP) were associated with prognosis in patients with AMI. However, whether the addition of the hs-CRP to Grace risk score could improve the predictive power of Grace risk score on the prognosis of patients with AMI is unclear.

HYPOTHESIS: We hypothesized that the inclusion of hs-CRP in the Grace risk score could improve the ability to correctly distinguish the occurrence of in-hospital outcomes.

METHODS: We retrospectively enrolled 1804 patients with AMI in the final analysis. Patients were divided into four groups by hs-CRP quartiles. The relation between hs-CRP and Grace risk score was analyzed by Spearman rank correlation. Logistic regression was used to identify independent risk factors. The predictive value of hs-CRP add to Grace risk score was evaluated by C-statistic, net reclassification improvement (NRI), integrated differentiation improvement (IDI), calibration plot, and decision curve analysis.

RESULTS: The hs-CRP and Grace risk score had a significantly positive correlation (r = .191, p < .001). hs-CRP combined with Grace risk score could improve the ability of Grace risk score alone to correctly redistinguish the occurrence of in-hospital outcome (C-statistic = 0.819, p < .001; NRI = 0.05956, p = .007; IDI = 0.0757, p < .001).

CONCLUSION: Admission hs-CRP level was a significant independent risk factor for in-hospital outcomes in patients with AMI. The inclusion of hs-CRP in the Grace risk score could improve the ability to correctly distinguish the occurrence of in-hospital outcomes.
