The Prevalence of Comorbidities in Individuals with Periodontitis in a Private Periodontal Referral Practice.

Periodontitis (PD) patients frequently suffer from comorbidities, necessitating increased attention to disease management and monitoring. The aim of this study is to describe the prevalence and patterns of comorbidities among patients with PD in a private periodontal referral practice. This study involved 3171 adults with PD.

Assessing motivational interviewing integrity in the Toddler Oral Health Intervention study.

Objectives: The Toddler Oral Health Intervention (TOHI) was launched in 2017 to promote oral health prevention at well-baby clinics, with a focus on parents with children aged 6-48 months. This study aims to evaluate the integrity of motivational interviewing (MI) as one of the core intervention pillars in the TOHI study.

Methods: The TOHI study was conducted at nine well-baby clinics in the central and southern regions of the Netherlands, with 11 trained oral health coaches (OHCs) delivering a tailored individual counselling programme.

The pace of life for forest trees.

Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such trade-offs vary across the world's forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (ranging from 1.

Unequal smiles: consequences of untreated dental caries in citizens living in vulnerable circumstances in the Netherlands: an exploratory pilot study.

The often poor oral health status of socioeconomically vulnerable adults is widely recognised. Nevertheless, research on it is scarce. To address this gap, this exploratory pilot study aimed to report on the prevalence of untreated caries and its clinical odontogenic consequences, as well as the associated Oral Health Related Quality of Life (OHRQoL) in a marginalised adult Dutch population.

The biogeography of the Amazonian tree flora.

We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local environmental conditions (especially soil nutrients and hydrology) and geographical regions.

Unraveling Calcium Absorption and Distribution in Peach and Nectarine during Fruit Development through Ca Isotope Labeling.

Calcium foliar applications are known to effectively enhance peach quality; however, the optimal implementation strategy regarding fruit developmental stages and cultivars remains unclear. In this study, three different moments of fruit Ca applications in peach and nectarine are tested: Early season, Mid-season, and Late season. For this aim, the Ca isotope was used as a tracer, enabling the quantification and location of the Ca derived from the foliar fertilizer.

Innovative all-in-one exome sequencing strategy for diagnostic genetic testing in male infertility: Validation and 10-month experience.

Background: Current guidelines indicate that patients with extreme oligozoospermia or azoospermia should be tested for chromosomal imbalances, azoospermia factor (AZF) deletions and/or CFTR variants. For other sperm abnormalities, no genetic diagnostics are recommended.

Objectives: To determine whether exome sequencing (ES) with combined copy number variant (CNV) and single nucleotide variant (SNV) analysis is a reliable first-tier method to replace current methods (validation study), and to evaluate the diagnostic yield after 10 months of implementation (evaluation study).

Inherited defects of piRNA biogenesis cause transposon de-repression, impaired spermatogenesis, and human male infertility.

piRNAs are crucial for transposon silencing, germ cell maturation, and fertility in male mice. Here, we report on the genetic landscape of piRNA dysfunction in humans and present 39 infertile men carrying biallelic variants in 14 different piRNA pathway genes, including PIWIL1, GTSF1, GPAT2, MAEL, TDRD1, and DDX4. In some affected men, the testicular phenotypes differ from those of the respective knockout mice and range from complete germ cell loss to the production of a few morphologically abnormal sperm.

Advances in assessing Ca, K, and Mn translocation in oak tree stems ( spp.).

As a part of the biogeochemical cycle, nutrient translocation plays an important role in enhancing the capacity of perennial plants to grow in nutrient-poor soils. Although leaf translocation has been extensively studied, nutrient translocation between wood rings has received considerably less attention, primarily because of methodological constraints. This study aimed to (i) evaluate the effects of different drying techniques on Ca, K, and Mn concentrations, (ii) calibrate a semi-quantitative method for obtaining ring-to-ring nutrient concentrations along wood cores, and (iii) develop a complete calculation chain for nutrient translocation.

The relationship between self-reported preventive and curative orientations of dentists and oral healthcare services provided to Dutch young patients: An observational study.

The aims of this study were to investigate the relationship between self-reported preventive and curative orientations of general dental practitioners (GDPs) and the oral healthcare services (OHS) they provided to patients under 18-years-old. And in addition, to determine which patient, GDP, and dental practice characteristics predicted the provision of preventive and curative care. GDPs in the Netherlands using dental software program Exquise (>2,000) were invited to participate in this study voluntarily.

The role of psychological distress in the relationship of financial strain with oral health and dental attendance in Dutch adults: A mediation analysis based on cross-sectional data.

Objectives: The study aimed to assess whether psychological distress mediates the association between financial strain and oral health and dental attendance in the Dutch adult population.

Methods: The study followed a cross-sectional design based on 2812 participants from the 2014 wave of the Dutch population-based GLOBE study. Financial strain was considered the exposure, while psychological distress measured with the Mental Health Inventory-5 (MHI-5) was the mediator.

Association of integration with oral health among Indian migrants living in the Netherlands.

Background: Limited data exist about the relationship between acculturation and oral health. Hence, the aim of this study was to assess the association of integration with self-reported oral health, behaviours, and oral healthcare utilization among Indian migrants living in the Netherlands, a cross sectional survey study.

Methods: Between February and April 2021, a random sample from Dutch municipalities was obtained for the Indian migrants living in the Netherlands (n = 147).

Longitudinal patterns of provided oral healthcare services to Dutch young patients: An observational study.

General dental practitioners (GDPs) differ in the preventive and curative care they provide to their young patients. This may be related to variation in the caries risk of patients, but also to differing opinions among GDPs about 'proper care'. Longitudinal data offers the possibility to make care patterns of GDPs comparable and to reveal possible treatment variation between GDPs.

Consistent patterns of common species across tropical tree communities.

Trees structure the Earth's most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge.

Mapping density, diversity and species-richness of the Amazon tree flora.

Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness.

Oral Health Status, Behaviours and Oral Healthcare Utilization among Indian Migrants Compared to the Host Population in the Netherlands: A Descriptive Cross-sectional Study.

The aim of this study was to assess the oral health status, oral health behaviours and oral healthcare utilization among Indian migrants living in the Netherlands and how they compare with the host population. Based on a random sample from Dutch municipalities, cross-sectional data were obtained for the Indian migrants living in the Netherlands (n = 148) and the host population (n = 244). A questionnaire was used to collect information on socio-demographic, self-reported oral health status, oral health behaviours and oral healthcare utilization.

More than 10,000 pre-Columbian earthworks are still hidden throughout Amazonia.

Indigenous societies are known to have occupied the Amazon basin for more than 12,000 years, but the scale of their influence on Amazonian forests remains uncertain. We report the discovery, using LIDAR (light detection and ranging) information from across the basin, of 24 previously undetected pre-Columbian earthworks beneath the forest canopy. Modeled distribution and abundance of large-scale archaeological sites across Amazonia suggest that between 10,272 and 23,648 sites remain to be discovered and that most will be found in the southwest.

Improved phenotypic classification of male infertility to promote discovery of genetic causes.

An increasing number of genes are being described in the context of non-syndromic male infertility. Linking the underlying genetic causes of non-syndromic male infertility with clinical data from patients is important to establish new genotype-phenotype correlations. This process can be facilitated by using universal nomenclature, but no standardized vocabulary is available in the field of non-syndromic male infertility.

Periodontitis is associated with multimorbidity in a large dental school population.

Aim: To investigate whether and which diseases co-occur with periodontitis (PD) to assess the prevalence of comorbidities and multimorbidity and to identify patterns and profiles of comorbidity and multimorbidity and the influence of demographic and lifestyle factors to identify distinct groups of multimorbid patients.

Materials And Methods: A database from the Academic Centre of Dentistry Amsterdam (ACTA) with 37,801 adult individuals containing information about demographic (age, sex, socio-economic position [SEP]) and lifestyle factors (smoking, alcohol use and addictive substance use) and PD and systemic diseases was constructed. PD assessment was based on clinical information by the use of claim codes and systemic diseases data were derived from self-reported medical history.

Douglas-fir plantations impact stream and groundwater chemistry in western Europe: Insights from three case studies in France and Luxembourg.

In rural areas, nitrate concentrations in surface waters most often originate from the leaching of excess N fertilizer in agricultural lands, whereas forested catchments often have good water quality. However, Douglas-fir plantations may induce nitrogen cycle unbalances which may lead to an excess of nitrate production in the soil. We hypothesize that the excess of production of nitrate in the soil and nitrate leaching to streamwater is greater in catchments planted with Douglas fir.

A multicentre double-blinded randomized controlled trial on the efficacy of laser-assisted hatching in patients with repeated implantation failure undergoing IVF or ICSI.

Study Question: Does assisted hatching increase the cumulative live birth rate in subfertile couples with repeated implantation failure?

Summary Answer: This study showed no evidence of effect for assisted hatching as an add-on in subfertile couples with repeated implantation failure.

What Is Known Already: The efficacy of assisted hatching, with regard to the live birth rate has not been convincingly demonstrated in randomized trials nor meta-analyses. It is suggested though that especially poor prognosis women, e.
