Thirty-five patients with complete LAM avulsion were included in the study. At 6 months after delivery, 51 LAM avulsions were observed in 35 patients (including bilateral LAM avulsion in 16 cases), of which 54.9% were right avulsions and 45.1% left avulsions. Furthermore, 11 (five right and six left) were type I LAM avulsions at the 6-month assessment, and all of these had disappeared 1 year after delivery. However, none of the type II LAM avulsions (23 right and 17 left) observed at 6 months had disappeared at the second ultrasound examination. There were no differences between the LAM areas detected at the first and second ultrasound examinations (10.2 ± 3.3 vs 9.3 ± 1.8; P = .404).

The type of LAM avulsion observed at 6 months after childbirth predicts LAM persistence at 1 year postpartum.

While the heat during the summer season may dehydrate the elderly, little is known about the seasonal variation in dehydration. This study aimed to investigate the seasonal variation in hydration status among the community-dwelling elderly in Japan.

We retrospectively analyzed the data collected after an overnight fast of adults aged ≥65 years who had no advanced kidney disease and underwent an annual health checkup at Nihon University Hospital between January and December 2019. Participants were classified according to their checkup date, whether summer (n = 265) or not summer (n = 638). The not summer group was subdivided into spring (n = 235), autumn (n = 213) and winter (n = 190).

Among the four seasons, the spring group showed the highest levels of plasma osmolality (306.1 ± 3.9 mOsm/L), urine specific gravity (1.0172 ± 0.0058) and prevalence rates of urine specific gravity ≥1.020 (34.0%). However, seasonal differences were clinically mild, and >90% of participants showed plasma osmolality ≥300 mOsm/L, indicating dehydration, in all four seasons. The summer group showed lower urine specific gravity levels (1.0150 ± 0.0062 vs. 1.0165 ± 0.0064, P < 0.001) and prevalence rates of urine specific gravity ≥1.020 (22.6% vs. 30.4%, P = 0.023) than did the not summer group. The summer season was associated with low urine specific gravity levels even after adjusting for the multiple linear regression model.

Japanese elderly after overnight fast are more dehydrated during the spring rather than the summer. Geriatr Gerontol Int 2020; 20 904-910.

In prosthodontics, the virtual articulator should be considered as an additional diagnostic and treatment planning tool to the mechanical articulator, especially in complex cases involving alterations to the vertical dimension of occlusion. Numerous authors have reported on the available digital methodologies used for the assembly of virtual arch models in a virtual articulator, focusing their attention on topics such as the virtual facebow and digital occlusal registration. To correctly simulate jaw movement, the jaw models have to be digitalized and properly mounted on the virtual articulator. The aim of this review was to discuss the current knowledge surrounding the various techniques and methodologies related to virtual mounting in dentistry, and whether virtual articulators will become commonplace in clinical practice in the future. This review also traces the history of the virtual articulator up to its current state and discusses recently developed approaches and workflows for virtual mounting based on current knowledge and technological devices.
To determine whether priming with 1 or 25Hz repetitive transcranial magnetic stimulation (rTMS) will enhance the benefits from treadmill training up to 3 months postintervention in people with Parkinson disease (PD), and to evaluate the underlying changes in cortical excitability.

This randomized double-blind, placebo-controlled trial was conducted between October 2016 and December 2018. Fifty-one participants with PD were randomized to receive 12 sessions of rTMS (25Hz, 1Hz, or sham) followed by treadmill training. All participants were assessed at baseline and 1 day, 1 month, and 3 months postintervention. Primary outcome was fastest walking speed, and secondary outcomes were timed up-and-go test (TUG), dual-task TUG (DT-TUG), motor section of the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS-III), and electrophysiological evaluation of cortical excitability by TMS.

The 1 and 25Hz rTMS groups produced a greater improvement in fastest walking speed at 1 day and 3 months h in turn suggests an alteration of the homeostatic plasticity range. Rebalancing cortical excitability by rTMS appears critical for plasticity induction. ANN NEUROL 2020;88933-945.
This study aims to evaluate the effect of erosive, abrasive, and erosive/abrasive challenges on the glaze layer of ceramic materials.

Ninety-five samples of monolithic zirconia (MZ) (LuxaCam Zircon HT-Plus) and lithium disilicate (LD) (IPS e.max CAD) were divided according to the response variables Surface roughness and surface loss (n = 10), evaluated with optical profilometry; surface topography, with scanning electron microscopy SEM (n = 3); and biofilm deposition, with microbiological assay (n = 5). The evaluations were performed in three different time evaluations (a) Sintered, (b) Glaze, and (c) Challenge (Erosion, Abrasion, and Erosion/Abrasion). Erosion consisted in immersing specimens in HCl solution, abrasion was performed with brushing machine, and erosion/abrasion consisted of a combination of the two previous protocols. Data were analyzed with parametric tests (P < 0.05).

MZ glaze layer presented significantly higher surface roughness (P = 0.00), surface loss (P = 0.03), and biofilm deposition (P = 0.
