Intersectional Bias in Healthcare—The Inequity Borne by the Patients: A Qualitative Study Open
Background Care should be neutral and equal, but normative beliefs may impact the interaction between patients and healthcare professionals in pain management. Objectives To explore how patients with jaw and neck pain perceive pain managem…
Navigating Health Care with Concurrent Jaw and Neck Pain: A Patient-Centered Perspective Open
Introduction: Concurrent pain in the jaw and neck is common; however, little is known about how it develops. Previous studies have focused mainly on biological factors with limited focus on psychosocial factors and patients’ perspectives. …
Jaw and head movement adjustments during jaw function—Comparisons between and within 13‐year‐olds and adults Open
Jaw–head movement coordination develops during adolescence. However, functional adjustments during this period remain poorly understood. This study aimed to characterize jaw and head movement adjustments in early adolescents and compare th…
Gender variability in palpation performance for temporomandibular disorders with three different methods: An experimental study Open
Gender differences in pain reporting and prevalence have been demonstrated. As gender of examiner also affects reporting of pain on palpation, the aim of this study was to evaluate the effects of examiner gender on palpation performance us…
Comparing Comparators in Generalization Bounds Open
We derive generic information-theoretic and PAC-Bayesian generalization bounds involving an arbitrary convex comparator function, which measures the discrepancy between the training and population loss. The bounds hold under the assumption…
Development of integrated jaw–neck motor function in children at 6, 10 and 13 years of age compared to adults: A kinematic longitudinal study Open
Background The functional integration of the jaw and neck motor systems, of great importance to everyday oral activities, is established in early childhood. Detailed characterisation of this developmental progress is largely unknown. Objec…
Clinical signs in the jaw and neck region following whiplash trauma—A 2‐year follow‐up Open
Background Pain in the orofacial region is often reported after whiplash trauma. However, prospective studies evaluating clinical signs related to orofacial pain and disability in whiplash populations are rare. The aim of the present study…
Adaptive Selective Sampling for Online Prediction with Experts Open
We consider online prediction of a binary sequence with expert advice. For this setting, we devise label-efficient forecasting algorithms, which use a selective sampling scheme that enables collecting much fewer labels than standard proced…
Evaluated CMI Bounds for Meta Learning: Tightness and Expressiveness Open
Recent work has established that the conditional mutual information (CMI) framework of Steinke and Zakynthinou (2020) is expressive enough to capture generalization guarantees in terms of algorithmic stability, VC dimension, and related co…
A New Family of Generalization Bounds Using Samplewise Evaluated CMI Open
We present a new family of information-theoretic generalization bounds, in which the training loss and the population loss are compared through a jointly convex function. This function is upper-bounded in terms of the disintegrated, sample…
Jaw–neck motor strategy during jaw‐opening with resistance load Open
Background The jaw and neck motor systems have a close functional integration but the effect of resistance load to the mandible during jaw opening on the jaw–neck integration is not known. Objectives To evaluate the effect of resistance lo…
Fast-Rate Loss Bounds via Conditional Information Measures with Applications to Neural Networks Open
We present a framework to derive bounds on the test loss of randomized learning algorithms for the case of bounded loss functions. Drawing from Steinke & Zakynthinou (2020), this framework leads to bounds that depend on the conditional inf…
Effects of a Ketogenic Diet on Muscle Fatigue in Healthy, Young, Normal-Weight Women: A Randomized Controlled Feeding Trial Open
Ketogenic low-carbohydrate high-fat (LCHF) diets are increasingly popular in broad sections of the population. The main objective of this study was to evaluate the effects of a non-energy-restricted ketogenic LCHF diet on muscle fatigue in…
Multimodal Sensory Stimulation of the Masseter Muscle Reduced Precision but Not Accuracy of Jaw-Opening Movements Open
A functional integration between the trigeminal and craniocervical sensorimotor systems has been demonstrated, with simultaneous jaw and head-neck movements during jaw opening-closing. We previously showed that pain induction in the masset…
Jaw‐neck movement integration in 6‐year‐old children differs from that of adults Open
Background A functional integration between the jaw and neck regions during purposive jaw movements is well described in adults, but there is a lack of knowledge of such integration during jaw function in children. Objectives To determine …
New constraints on inelastic dark matter from IceCube Open
We study the capture and subsequent annihilation of inelastic dark matter (DM) in the Sun, placing constraints on the DM-nucleon scattering cross section from the null result of the IceCube neutrino telescope. We then compare such constrai…
A high prevalence of TMD is related to somatic awareness and pain intensity among healthy dental students Open
The prevalence of any DC/TMD diagnosis was 30%. The most prevalent TMD diagnosis was myalgia. Individuals with a TMD-pain diagnosis (i.e. myalgia or arthralgia) reported significantly higher pain intensity levels according to the Graded Ch…
Does induced masseter muscle pain affect integrated jaw-neck movements similarly in men and women? Open
Normal jaw opening-closing involves simultaneous jaw and head-neck movements. We previously showed that, in men, integrated jaw-neck movements during jaw function are altered by induced masseter muscle pain. The aim of this study was to in…
Association between plasma concentrations of linoleic acid-derived oxylipins and the perceived pain scores in an exploratory study in women with chronic neck pain Open
The data obtained in this exploratory study indicate that although no group differences are seen in plasma lipid concentrations, there is an association between the NRSday scores and the 9- and 13-hydroxy-octadecadienoic acid levels. Wheth…
Myosin light chain and calcium regulating protein differences in chronic musculoskeletal neck and shoulder pain Open
Proteomic screening analysis has detected myosin light chain (MLC) as a protein implied to be involved in chronic musculoskeletal neck and shoulder pain. Several analyses of MLC proteins have stated a difference in phosphorylation being th…
