Objectives: The primary aim is to assess differences in accuracy of orthodontic bracket positioning between fully digital indirect bracket bonding (IDB) and conventional direct bracket bonding (DBB). The secondary aims are to assess differences in bracket bonding failures, bracket repositioning need, clinician experience and patient satisfaction.

Materials And Methods: This prospective study was designed as a split-mouth randomized clinical trial.

The Biting Colon: An Unfortunate Nightmare for a Healthy but Anxious Patient.

A 48-year-old female with no significant past medical history presented to the emergency department with an uncommon scenario after accidentally ingesting a three-unit dental bridge, leading to its impaction within the lower gastrointestinal tract. Despite initial conservative management with laxatives aimed at facilitating spontaneous passage, the foreign body remained lodged in the colon. Subsequently, the patient underwent endoscopic intervention via colonoscopy, during which the dental bridge was successfully extracted.

Interobserver agreement of current and new proposed endoscopic scores for postoperative recurrence in Crohn's disease.

Background And Aims: The modified Rutgeerts score (mRS) is widely used for the assessment of endoscopic postoperative recurrence (ePOR) in Crohn's disease (CD) after ileocolic resection to guide therapeutic decisions. To improve the validity and prognostic value of this endoscopic assessment, 2 new scores have been proposed. This study assessed the interobserver agreement of the current score (mRS) and the new endoscopic score for ePOR in CD.

Novel SK channel positive modulators prevent ferroptosis and excitotoxicity in neuronal cells.

Small conductance calcium-activated potassium (SK) channel activity has been proposed to play a role in the pathology of several neurological diseases. Besides regulating plasma membrane excitability, SK channel activation provides neuroprotection against ferroptotic cell death by reducing mitochondrial Ca uptake and reactive oxygen species (ROS). In this study, we employed a multifaceted approach, integrating structure-based and computational techniques, to strategically design and synthesize an innovative class of potent small-molecule SK2 channel modifiers through highly efficient multicomponent reactions (MCRs).

The effect of surface roughening on the success of orthodontic mini-implants: A systematic review and meta-analysis.

Introduction: Orthodontic mini-implants are a widely accepted treatment modality in orthodontics; however, the failure rate is moderately high. Surface roughening is the golden standard in conventional oral implantology, and this may prove beneficial for orthodontic mini-implants as well. The objective of this systematic review is to assess the effect of surface roughening on the success rate of orthodontic mini-implants in both adolescent and adult patients undergoing orthodontic treatment.

Residual β-Cell Function Is Associated With Longer Time in Range in Individuals With Type 1 Diabetes.

Objective: Little is known about the influence of residual islet function on glycemic control in type 1 diabetes (T1D). We investigated the associations between residual β-cell function and metrics of continuous glucose monitoring (CGM) in individuals with T1D.

Research Design And Methods: In this cross-sectional cohort comprising 489 individuals (64% female, age 41.

Predicting self-perceived general health status using machine learning: an external exposome study.

Background: Self-perceived general health (SPGH) is a general health indicator commonly used in epidemiological research and is associated with a wide range of exposures from different domains. However, most studies on SPGH only investigated a limited set of exposures and did not take the entire external exposome into account. We aimed to develop predictive models for SPGH based on exposome datasets using machine learning techniques and identify the most important predictors of poor SPGH status.

Influence of bisphosphonate treatment on bone substitute performance in osteoporotic conditions.

Objective: Considering the elevated number of osteoporotic patients in need of bone graft procedures, we here evaluated the effect of alendronate (ALN) treatment on the regeneration of bone defects in osteoporotic rats. Bone formation was histologically and histomorphometrically assessed in rat femoral condyle bone defects filled with bone graft (Bio-Oss®) or left empty.

Methods: Male Wistar rats were induced osteoporotic through orchidectomy (ORX) and SHAM-operated.

Effectiveness and safety of tofacitinib for ulcerative colitis: two-year results of the ICC Registry.

Background: Tofacitinib is an oral Janus kinase (JAK) inhibitor and is registered for the treatment of ulcerative colitis (UC). The effectiveness of tofacitinib has been evaluated up to 12 months of treatment.

Aim: The aim of this study was to assess the effectiveness and safety of 24 months of tofacitinib use in UC patients in the Netherlands.

A new quantitative 3D gap area measurement of fracture displacement of intra-articular distal radius fractures: Reliability and clinical applicability.

Introduction: Gap and step-off measurements are generally used in the surgical decision-making process of distal radius fractures. Unfortunately, there is no consensus on treatment choice as these measurements are prone to inter- and intraobserver variability. In this study, we aim to introduce a new 3D fracture quantification method and compare it to conventional fracture analysis.

Using random forest to identify longitudinal predictors of health in a 30-year cohort study.

Due to the wealth of exposome data from longitudinal cohort studies that is currently available, the need for methods to adequately analyze these data is growing. We propose an approach in which machine learning is used to identify longitudinal exposome-related predictors of health, and illustrate its potential through an application. Our application involves studying the relation between exposome and self-perceived health based on the 30-year running Doetinchem Cohort Study.

Increasing Seaweed Consumption in the Netherlands and Portugal and the Consequences for the Intake of Iodine, Sodium, and Exposure to Chemical Contaminants: A Risk-Benefit Study.

Seaweed has a high potential for nourishing the future planet. However, besides being beneficial, it also contains adverse components; this poses the question whether consumption of seaweed foods overall contributes beneficially or detrimentally to human health, and hence if their consumption should be promoted or restricted. This study evaluated the impact of substituting regular foods with seaweed foods in the diet, both in terms of nutritional quality ( iodine and sodium) and food safety ( arsenic, cadmium, lead, and mercury).

Innovative implant design for continuous implant stability: A mechanical and histological experimental study in the iliac crest of goats.

Objectives: this in vivo study reports on mechanical torque data as well as the biological evaluation up to 6 weeks after placement of implants with a unique wide knife thread design in a goat iliac crest model. We hypothesized that implants with this thread design would show substantial primary stability at a continuous level toward secondary stability.

Methods: 64 MegaGen Anyridge® implants were used with diameters 3.

Impact of autism genetic risk on brain connectivity: a mechanism for the female protective effect.

The biological mechanisms underlying the greater prevalence of autism spectrum disorder in males than females remain poorly understood. One hypothesis posits that this female protective effect arises from genetic load for autism spectrum disorder differentially impacting male and female brains. To test this hypothesis, we investigated the impact of cumulative genetic risk for autism spectrum disorder on functional brain connectivity in a balanced sample of boys and girls with autism spectrum disorder and typically developing boys and girls (127 youth, ages 8-17).

Risk-benefit in food safety and nutrition - Outcome of the 2019 Parma Summer School.

Risk-benefit assessment is the comparison of the risk of a situation to its related benefits, i.e. a comparison of scenarios estimating the overall health impact.

Faecal microbiota transplantation halts progression of human new-onset type 1 diabetes in a randomised controlled trial.

Objective: Type 1 diabetes (T1D) is characterised by islet autoimmunity and beta cell destruction. A gut microbiota-immunological interplay is involved in the pathophysiology of T1D. We studied microbiota-mediated effects on disease progression in patients with type 1 diabetes using faecal microbiota transplantation (FMT).

Genomic analysis of European bovine Staphylococcus aureus from clinical versus subclinical mastitis.

Intramammary infections (IMI) with Staphylococcus aureus are a common cause of bovine mastitis and can result in both clinical (CM) or subclinical mastitis (SCM). Although bacterial isolates of S. aureus differ in their virulence potential it is largely unclear which bacterial virulence factors are responsible for increased clinical severity.

A portable primary radar for general aviation.

A detailed situation awareness of the local environment is essential for safe flight in General Aviation. When operating under Visual Flight Rules, eyesight is crucial for maintaining situation awareness and objects may be overlooked. Technical solutions such as Flarm have been sought, but they only work on a basis of co-operation: obstacles without the proper equipment are invisible.

[How effective is Blue®m?].

In PubMed, 1 randomised controlled trial and 1 summary of a trial were found in which a Blue®m product was examined. Case studies were also found on the Blue®m website, none of which met the CARE criteria for describing case studies.

Tofacitinib for ulcerative colitis: results of the prospective Dutch Initiative on Crohn and Colitis (ICC) registry.

Background: Tofacitinib is a Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC).

Aim: To evaluate effectiveness, safety and use of tofacitinib in daily practice.

Methods: UC patients initiating tofacitinib were prospectively enrolled in 15 hospitals in the Netherlands.

Imaging-genetics of sex differences in ASD: distinct effects of OXTR variants on brain connectivity.

Autism spectrum disorder (ASD) is more prevalent in males than in females, but the neurobiological mechanisms that give rise to this sex-bias are poorly understood. The female protective hypothesis suggests that the manifestation of ASD in females requires higher cumulative genetic and environmental risk relative to males. Here, we test this hypothesis by assessing the additive impact of several ASD-associated OXTR variants on reward network resting-state functional connectivity in males and females with and without ASD, and explore how genotype, sex, and diagnosis relate to heterogeneity in neuroendophenotypes.

Activation of a Bovine Mammary Epithelial Cell Line by Ruminant-Associated is Lineage Dependent.

Bovine mastitis is a costly disease to the dairy industry and intramammary infections (IMI) with are a major cause of mastitis. strains responsible for mastitis in cattle predominantly belong to ruminant-associated clonal complexes (CCs). Recognition of pathogens by bovine mammary epithelial cells (bMEC) plays a key role in activation of immune responsiveness during IMI.
