Optimizing fuel treatments for community wildfire mitigation planning.

Fuel management is undertaken to mitigate the adverse consequences of wildfire. Finite mitigation budgets demand selective prioritization of forest stands for targeted fuel reduction treatments. A range of modeling methods have been used to identifiy optimal fuel treatment plans at various spatial and temporal scales of investigation; however, strategic analysis of fuel management alternatives can involve a range of limitations and challenges, including the prevalence of one-time solutions, static models lacking dynamic adaptability, and challenges in accounting for the stochastic nature of fire behaviour.

Changes in Body Weight and Risk Factors for Overweight and Obesity in 5-6-Year-Old Children Attending School in Geneva.

The prevalence of obesity and overweight in children is increasing in industrialized countries. Monitoring the evolution of these phenomena is essential for understanding prevention and health promotion programs. This study aims to present the analysis of anthropometric data collected by school nurses from the School Health Service of Geneva (Service de santé de l'enfance et de la jeunesse) for children aged 5 to 6 years during the 2021-2022 school year, as well as describe the trends in overweight and obesity from 2003-2004 to 2021-2022.

Strengthening Early Childhood Education and Care in a "Childcare Desert".

High-quality Early Childhood Education and Care (ECEC) is an important component of thriving communities. It is central to the socio-emotional and intellectual growth of young children, to the ability of parents to go to work, and to the ability of employers to find and retain workers. Despite this centrality, there is a profound shortage of ECEC in many communities, which has only been made worse by COVID-19.

Evaluating dose constraints for radiation induced liver damage following magnetic resonance image guided Stereotactic Body radiotherapy.

This study reports dose corresponding to visible radiation induced liver damage following Stereotactic Body Radiation Therapy (SBRT) for liver metastasis, and the optimal time for follow up scans using post radiation imaging. Diagnostic magnetic resonance scans of nine patients treated with liver SBRT using a 0.35 T MRI-guided radiotherapy system were analyzed.

Reduction of cardiac dose using respiratory-gated MR-linac plans for gastro-esophageal junction cancer.

Treatment of locally advanced adenocarcinoma of the gastroesophageal junction (GEJ) with chemoradiation may be associated with high rates of symptomatic cardiac toxicity. Large margins are typically required to ensure coverage of GEJ tumors with free-breathing volumetric modulated arc therapy (VMAT) radiotherapy. The purpose of this study is to determine whether treatment with tighter margins enabled by maximum-inhalation breath hold (MIBH)-gated intensity modulated radiation therapy (IMRT) on an integrated MRI-linear accelerator system (MR-linac) can decrease radiation doses to the heart and cardiac substructures.

Modified Tunnel Technique Combined with Enamel Matrix Derivative: A Minimally Invasive Treatment for Single or Multiple Class I Recession Defects.

Purpose: Gingival recession is a significant problem in the esthetic zone. Connective tissue grafts have been considered the gold standard, but they need a donor site that increases morbidity and discomfort for the patient.The purpose of the present study was to evaluate the clinical results of a modified tunnel technique that consists of replacing the connective tissue graft by enamel matrix derivative, in the treatment of Miller Class I recession defects.

Sociodemographic and Economic Determinants of Overweight and Obesity for Public-school Children in Geneva State, Switzerland: A Cross-sectional Study.

Background: Obesity among children and adolescents is a growing public health problem. The purpose of this study is to assess the prevalence, socioeconomic and demographic determinants of overweight and obesity in schoolchildren from Geneva.

Methods: A cross-sectional study was undertaken at the Public School of Geneva canton in Switzerland.

A comparison of the spatial dependence of body mass index among adults and children in a Swiss general population.

Background: Body mass index (BMI) may cluster in space among adults and be spatially dependent. Whether BMI clusters among children and how age-specific BMI clusters are related remains unknown. We aimed to identify and compare the spatial dependence of BMI in adults and children in a Swiss general population, taking into account the area's income level.

Teaching an Old Log New Tricks with Machine Learning.

To most people, the log file would not be considered an exciting area in technology today. However, these relatively benign, slowly growing data sources can drive large business transformations when combined with modern-day analytics. Accenture Technology Labs has built a new framework that helps to expand existing vendor solutions to create new methods of gaining insights from these benevolent information springs.

EBV infection is common in gingival epithelial cells of the periodontium and worsens during chronic periodontitis.

An amplifying role for oral epithelial cells (ECs) in Epstein-Barr Virus (EBV) infection has been postulated to explain oral viral shedding. However, while lytic or latent EBV infections of oro/nasopharyngeal ECs are commonly detected under pathological conditions, detection of EBV-infected ECs in healthy conditions is very rare. In this study, a simple non-surgical tissue sampling procedure was used to investigate EBV infection in the periodontal epithelium that surrounds and attaches teeth to the gingiva.

[Prescribing physical activity to reluctant adolescents: why, how and for what benefits?].

Family doctors often face requests to exempt adolescents from physical education classes. Knowledge of the goals of physical education in compulsory and post-compulsory education can help the practitioner discuss this important subject and its physical and mental health implications. In Geneva, an innovative programme called "EPI" (individualised physical activity at the secondary school level) has been developed and doctors can refer adolescents who otherwise would not be able to participate in conventional gym classes.

Reirradiation of large-volume recurrent glioma with pulsed reduced-dose-rate radiotherapy.

Purpose: Pulsed reduced-dose-rate radiotherapy (PRDR) is a reirradiation technique that reduces the effective dose rate and increases the treatment time, allowing sublethal damage repair during irradiation.

Patients And Methods: A total of 103 patients with recurrent glioma underwent reirradiation using PRDR (86 considered to have Grade 4 at PRDR). PRDR was delivered using a series of 0.

Evolution of overweight and obesity among elementary school children in Geneva.

Questions Under Study: In view of the alarming trend in childhood obesity (O) and overweight (OW) observed in certain countries, the aim of the study is to measure the prevalence of O and OW in successive cohorts of elementary school children in Geneva.

Methods: All 5-6-year-old children attending public schools in the Canton of Geneva were measured and weighed during a systematic health check at school from 2003 to 2008. BMI was calculated and plotted on standardised BMI for age tables, using Cole's and Kromeyer's references.

[Preprosthetic surgery of the edentulous maxilla: vestibular deepening with the aid of the CO2 laser].

Vestibular deepening for maxillary edentulous patients is mainly indicated once instability cannot be reached due to important bone resorption. Vestibular deepening with CO2 super-pulsed laser enhance, in a bloodless environment, sustentation as well retention of those full dentures in good operative conditions as compared with conventional techniques.

Intraoral metal laser welding: a case report.

The possibility of laser welding of dental prostheses offers great advantages: first, the operator has the possibility of welding on the master model, which decreases the number of passages and thus the possibility of errors and damage, and secondly, the patient attends only a few sessions, and, due to the possibility of fixing the damaged prostheses, there is no need to resort to the technician's laboratory. In a previous study we described the experimental phases of intraoral welding, from the in vitro model on animal jaws with evaluations of the temperature variations during welding through thermal chamber and type K thermocouples. In this study we describe the intraoral welding in vivo on human subjects by using, as in the previous study, a fibre-delivered neodymium:yttrium-aluminum-garnet (Nd:YAG) laser.

Intra-oral laser welding: an in vitro evaluation of thermal increase.

The neodymium:yttrium-aluminium-garnet (Nd:YAG) laser is currently used in dental laboratories to weld metals on dental prostheses. Recently, the use of Nd:YAG has been suggested so that dentists themselves can repair broken fixed, removable and orthodontic prostheses by welding metals directly in the mouth. This work aimed to evaluate, through a four k-type thermocouple system on calf jaws, the thermal increase in the biological structures close to the metal parts during laser welding.

Pulsed reduced dose-rate radiotherapy: a novel locoregional retreatment strategy for breast cancer recurrence in the previously irradiated chest wall, axilla, or supraclavicular region.

Purpose: Reirradiation of breast cancer locoregional recurrence (LRR) in the setting of prior post-mastectomy radiation poses a significant clinical challenge due to the high risk for severe toxicity. In an attempt to reduce these toxicities, we have developed pulsed reduced dose-rate radiotherapy (PRDR), a reirradiation technique in which a series of 0.2 Gy pulses separated by 3-min time intervals is delivered, creating an apparent dose rate of 0.
