Both homocysteine (Hcy) and asymmetric dimethylarginine (ADMA) induce endothelial dysfunction. However, the impact of both elevations on all-cause death is not known. We investigated the association between elevations of Hcy or ADMA and all-cause death in a general population.
A total of 517 subjects (224 men, 293 women; mean age, 62.8 years) were recruited from a population-based survey in 1999 in Tanushimaru, and we measured fasting plasma Hcy and ADMA levels. We followed them up for over 20 years and examined the effect on mortality using Cox proportional hazard regression model.
The mean follow-up years were 17.7 (1.8-20.8). In this period, 182 subjects have died (35.2%). The correlation between Hcy and ADMA was high (r=0.194; p<0.001). With Cox regression analysis after adjustments for age and sex, elevated log transformed Hcy levels were significantly associated with all-cause death (p=0.028). When Hcy and ADMA levels were divided into quintiles, the hierarchical model showed the synergistic effect of Hcy and ADMA on all-cause death.
This is the first report that we have measured Hcy and ADMA levels simultaneously in this community-dwelling Japanese, and we demonstrated that combined elevations of Hcy and ADMA had big impact on all-cause death in this epidemiological study.

Multiple stakeholders are interested in improving patient experience after primary total hip arthroplasty due to shifts toward patient-centered care. Patient free-text narratives are a potentially valuable but largely unexplored source of data.
The records of 383 patients who underwent primary total hip arthroplasty between August 2016 and August 2019 were combined with vendor-supplied patient satisfaction data, which included patient free-text comments and the Press Ganey satisfaction survey. A total of 1295 patient comments were analyzed for sentiment, and negative comments were categorized into nine themes. Postoperative outcomes, patient-reported outcome measures, and traditional measures of satisfaction were compared between patients who provided a negative comment vs those who did not. Multivariable regression was used to determine perioperative variables associated with providing a negative comment.
Of the 1295 patient comments 54% were positive, 24% were negative, 10% were mixed, and 12% were neutral. Top two themes of negative comments were room condition (25%) and inefficient communication (23%). There were no differences in studied outcomes (eg. peak pain intensity, length of stay, or improvements in hip injury and osteoarthritis outcome scores Jr. and pain visual analog scale scores at 6-week follow-up) between those who provided negative comments vs those who did not (P > .05). However, patients who made negative comments were less likely to recommend their hospital care to peers (P < .001). Finally, patients who had >2 allergies (P= .024) were more likely to provide negative comments.
The present study demonstrates that patient satisfaction appears not to be a reliable sole proxy for traditional objective outcome measures of pain relief and functional improvement.

Flapless implant placement with immediate functional loadinghas been reported in anterior locations. However, data on posterior locations are lacking.
The purpose of this randomized controlled trial was to determine and compare clinical outcomes of flap versus flapless surgically placed single posterior mandibular dental implants subjected to immediate functional loading.
Participants with missing mandibular first molar teeth were recruited and randomized into 2 groups (n=51) flapped and flapless. Dental implants were surgically placed and loaded immediately with interim restorations following implant protective occlusion. Outcome measures were implant failure, crestal bone loss, and periodontal parameters modified plaque index, modified sulcus bleeding index, and pocket depths. Outcome data were recorded at baseline, 6-month, and 12-month follow-up visits. Cone beam computed tomographyscans were used to calculate crestal bone loss, and periodontal outcomes were recorded by using a resin covered periodotional loading could be considered as an appropriate treatment option for providing functional restorations on the day of implant placement with minimal surgical intervention, reducing crestal bone loss, and periodontal complications.
Flapless implant insertion with immediate functional loading could be considered as an appropriate treatment option for providing functional restorations on the day of implant placement with minimal surgical intervention, reducing crestal bone loss, and periodontal complications.Making an intraoral digital scan of the emergence profile is a clinical challenge. The peri-implant soft tissue collapses after removal of an interim prosthesis, which compromises the correct design of a definitive implant-supported prosthesis. Although techniques are available for digitally reducing such a distortion, achieving a correct alignment of scans to replicate the internal and external characteristics of the peri-implant tissue is still challenging. This article describes an alternative technique for achieving a precise alignment of the peri-implant soft tissue emergence profile generated with an interim prosthesis.
A consensus on the accuracy of additively manufactured casts in comparison with those fabricated by using conventional techniques for fixed dental prostheses is lacking.
The purpose of this systematic review was to determine the accuracy of additively manufactured casts for tooth- or implant-supported fixed dental prostheses in comparison with that of gypsum casts.
This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database (CDR42020161006). Eight databases were searched in December 2019 and updated in September 2020. Studies evaluating the dimensional accuracy of additively manufactured casts for fixed dental prostheses in comparison with that of gypsum casts were included. An adapted checklist for reporting invitro studies (Checklist for Reporting Invitro Studies guidelines) was used to assess the risk of bias.
Eight studies evaluating tooth-suy, printing settings, and postprocessing procedures plays an essential role in the accuracy of additively manufactured casts. Clinical studies are required to confirm these findings.
Titanium-zirconium (Ti-Zr) alloy (Roxolid) narrow-diameter implants (NDIs) have been widely used for implant-supported prostheses in anterior and posterior regions in the jaws. However, the relationship between implant location and clinical outcome remains unclear.
The purpose of this clinical study was to evaluate and compare the clinical and radiographic outcomes of NDIs placed in different regions of the jaws in both smokers and nonsmokers.
Eighty-four participants scheduled to receive NDIs for tooth rehabilitation were included, and the inserted NDIs were divided into 3 groups depending on their locations implants used to restore anterior teeth, implants used to restore premolars, and implants used to restore molars. Crestal bone loss (CBL), implant survival and success rates, bleeding on probing (BOP), and pocket probing depth (PPD) were evaluated 6 and 12 months after implant loading (α=.017 for implant survival and success rates after Bonferroni correction, α=.05 for other parameters).
Statistione loss. Caution should be taken when restoring molars for smokers with NDIs.
High-performance thermoplastics have been adopted as an alternative restorative material to metal or ceramics. Sabutoclax manufacturer However, a straightforward surface modification process to provide a durable bond strength between the polymer and the veneering material is lacking.
The purpose of this invitro study was to evaluate the shear bond strength (SBS) of different veneering resin materials to polyetherketoneketone (PEKK) after different surface treatments.
Rectangular (7×7×2 mm) PEKK specimens (N=120) were randomly allocated to the following 6 groups (n=20) untreated (Cnt); nonthermal plasma (NTP) treated; tribochemical silica airborne-particle abrasion with 30-μm silica-modified Al
O
(Tbc); abraded with a coarse-grit diamond rotary instrument (Ab); tribochemical silica airborne-particle abrasion+ plasma treated (Tbc_NTP); abraded+ plasma treated (Ab_NTP). After a bonding agent (PEKK Bond) was applied to the specimens, each group was divided into 2 subgroups according to the applied veneering resin materials polyg resin material is recommended over PMMA.
The bonding capacity of PEKK to the PMMA and NHC veneering resin materials can be significantly improved by using tribochemical silica airborne-particle abrasion alone or with nonthermal plasma surface treatment techniques. Furthermore, using NHC veneering resin material is recommended over PMMA.
The effect of repeated firing on the marginal and internal adaptation of copings fabricated with different techniques, thicknesses, and alloy types is unclear.
The purpose of this invitro study was to compare the effects of repeated firing cycles on the marginal and internal adaptation of metal copings with different thicknesses fabricated by using casting, selective laser sintering (SLS), presintered soft metal milling (PSMM), postsintered hard metal milling (PHMM), and titanium millingmethods.
Single-unit implant-supported copings (N=120) were fabricated with 0.5-mm and 1.5-mm thicknesses, and porcelain was applied in accordance with the manufacturer's instructions (n=12). The marginal and internal adaptation of the metal copings were examined before the firing cycles and after the fourth and seventh firing cycles by using a silicone replica technique with a stereomicroscope at×80 magnification. The results were analyzed by using 3-way analysis of variance for repeated measurements on a single factor, 2-way analysis of variance, and an independent samples t test (α=.05).
As a result of the repeated firing cycles, the changes in the marginal discrepancy and internal discrepancyvalues in the PSMM, PHMM, and titanium milling groups and the change in the internal discrepancy value in the casting group were statistically significantly different (P<.05). The effect of the interaction of the firing, method, and thickness difference on the marginal discrepancy and internal discrepancy values was not statistically significantly different (P>.05).
After the firing cycles, the PSMM, SLS, and titanium milling groups were found to have better marginal and internal adaptation for both thicknesses than the casting and PHMM groups.
