The study aim was to evaluate the associations among the presence of wisdom teeth (third molars, M3), periodontal disease, and serum C-reactive protein (CRP) in the US adult population, thus to generate population-based evidence to inform heart disease prevention and dental care.

We performed secondary data analysis of the 2009-2010 National Health and Nutrition Examination Survey (NHANES), and included 3752 people aged 30 years and older who participated in the periodontal examination.

Descriptive analyses were performed to determine the prevalence of M3 presence, periodontal disease, and elevated CRP. Multivariate logistic regression modeling was used to determine the association between M3 presence, periodontal disease, and elevated CRP.

The prevalence of M3 presence, periodontal disease (probing periodontal pockets depth (PPD)≥ 4mm), and elevated serum C-reactive protein level (≥5mg/L) was 39%, 41%, and 19% respectively. M3 presence was highest among men, younger adults, Blacks and Hispanics compapresence alone is not associated with elevated CRP. Further research into cardiovascular health hazards related to the retention of wisdom teeth is needed, including examining possible relationships with other inflammatory factors.

In high-income countries, there is a positive relationship between neighborhood-level crime and cardiovascular risk factors (CRFs) in adolescence. A few studies that examined this association in low- and middle-income countries yielded inconsistent results. The aim of our study was to analyze the associations between homicide rates and prevalence rates of CRFs in adolescents living in Brazilian municipalities.

Cross-sectional ecologic study.

An ecologic study was conducted to evaluate associations between homicide rates and CRFs in 122 municipalities included in the Study of Cardiovascular Risk Factors in Adolescents (Portuguese acronym, ERICA). The following CRFs were evaluated adiposity (overweight/obese), sedentary behavior (screen time ≥3h per day), high waist circumference (between 10 and 16 years, percentile ≥90; 16-17 years, ≥90cm for men and ≥80cm for women), low high-density lipoproteins (HDL) levels (<45mg/dl), alcohol use (≥1 drink in the last 30 days) and hypertension (≥percentile 95th). ICA municipalities, although high prevalence rates of homicides and CRFs are important public health concerns, no significant associations were found between these variables.

In ERICA municipalities, although high prevalence rates of homicides and CRFs are important public health concerns, no significant associations were found between these variables.Driving under the influence (DUI) is illegal in the United States because a driver’s mental and motor skills can be seriously impaired by alcohol or drugs. Consequently, DUI violators’ involvement in severe crashes is high. Motivated by the spatial and temporal nature of traffic crashes, this study introduces an integrated spatio-temporal approach to analyzing highway safety data. Specifically, this study estimates Geographically and Temporally Weighted Regression (GTWR) models to understand the consequences of DUI in crashes. GTWR can theoretically outperform traditional regression methods by accounting for unobserved heterogeneity that may be related to the location and time of a crash. Using Southeast Michigan crash data, this study finds that DUI is associated with a 25% higher likelihood of injury in a crash. The association between injury severity and DUI varies significantly across space and time. From the spatial aspect, DUI crashes in rural or small-town areas are more likely to cause injuries than urban crashes. From the temporal aspect, different times are associated with varying relationships between injury severity and DUI. If focusing on DUI crashes in late nights and early mornings, on Fridays, the entire northeast part from Clinton Charter Township to Port Huron is associated with severer injuries than other regions including Detroit’s urban area and its south. On Mondays, the DUI crashes in the northwest are also more likely to cause severe injuries. The methodology introduced in this study takes advantage of modern computational tools and localized crash/inventory data. This method offers researchers and practitioners an opportunity to understand highway safety outcomes in great spatial and temporal details and customize safety countermeasures for specific locations and times such as saturation patrols.The aim of this work was to evaluate the influence of high-intensity ultrasound (HIUS) treatment on whey protein isolate (WPI) molecular structure as a previous step for complex coacervation (CC) with kappa-carrageenan (KC) and its influence on CC functional properties. Protein suspension of WPI (1% w/w) was treated with an ultrasound probe (24 kHz, 2 and 4 min, at 50 and 100% amplitude), non HIUS pretreated WPI was used as a control. Coacervation was achieved by mixing WPI and KC dispersions (10 min). Time and amplitude of the sonication treatment had a direct effect on the molecular structure of the protein, FTIR-ATR analysis detected changes on pretreated WPI secondary structure (1600-1700 cm-1) after sonication. CC electrostatic interactions were detected between WPI positive regions, KC sulfate group (1200-1260 cm-1), and the anhydrous oxygen of the 3,6 anhydro-D-galactose (940-1066 cm-1) with a partial negative charge. After ultrasound treatment, a progressive decrease in WPI particle size (nm) was detected. Rheology results showed pseudoplastic behavior for both, KC and CC, with a significant change on the viscosity level. BMS-794833 cost Further, volume increment, stability, and expansion percentages of CC foams were improved using WPI sonicated. Besides, HIUS treatment had a positive effect on the emulsifying properties of the CC, increasing the time emulsion stability percentage. HIUS proved to be an efficient tool to improve functional properties in WPI-KC CC.The sonocatalytic degradation of EDTA (C0 = 5 10-3 M) in aqueous solutions was studied under 345 kHz (Pac = 0.25 W mL-1) ultrasound at 22-51 °C, Ar/20%O2, Ar or air, and in the presence of metallic titanium (Ti0) or core-shell Ti@TiO2 nanoparticles (NPs). Ti@TiO2 NPs have been obtained using simultaneous action of hydrothermal conditions (100-214 °C, autogenic pressure P = 1.0-19.0 bar) and 20 kHz ultrasound, called sonohydrothermal (SHT) treatment, on Ti0 NPs in pure water. Ti0 is composed of quasi-spherical particles (30-150 nm) of metallic titanium coated with a metastable titanium suboxide Ti3O. SHT treatment at 150-214 °C leads to the oxidation of Ti3O and partial oxidation of Ti0 and formation of nanocrystalline shell (10-20 nm) composed of TiO2 anatase. It was found that Ti0 NPs do not exhibit catalytic activity in the absence of ultrasound. Moreover, Ti0 NPs remain inactive under ultrasound in the absence of oxygen. However, significant acceleration of EDTA degradation was achieved during sonication in the presence of Ti0 NPs and Ar/20%O2 gas mixture.
