This study aims to evaluate the adaptability and validity of the Oral Health Values Scale in the Hindi language (H-OHVS). METHODOLOGY: A total of 240 adults participated in the study that was carried out from July to November 2022. An offline one-to-one survey was carried out to collect data by an investigator blinded to the study protocol...

Patients diagnosed with oral cancer frequently exhibit an increased likelihood of experiencing common dental conditions, lower dental health literacy, and a decline in their overall quality of life. However, there is limited understanding on the impact of oral health values on these patients. This study aims to explore the oral health status and their oral health determinants and reported outcomes in patients with oral squamous cell carcinoma (OSCC) at the Instituto Português de Oncologia de Lisboa Francisco Gentil ...

BACKGROUND: Hemorrhagic fever with renal syndrome (HFRS) caused by Orthohantavirus (OHV) and scrub typhus (ST) caused by Orientia tsutsugamushi (OT) are two infectious diseases prevalent in southwest China. Rodents are the natural host and the main source of the two diseases. OT infection to humans is usually resulted from bite of an infective chigger mite on rodents, and OHV is transmitted through contact or inhalation of aerosols and secretions from infected rodent. The use of antibiotics and hormones is crucial for infectious diseases, although the clinical manifestations are not obvious and a definitive diagnosis becomes more difficult in the presence of these drugs...

The Temblor Mountain Special Recreation Area (SRMA) on the western flank of the San Joaquin Valley, CA, is located in the endemic area of Coccidioides, a fungal pathogen responsible for the increasing incidence of coccidioidomycosis (Valley fever). Recreationists in the SRMA, such as off-highway vehicle (OHV) drivers and mountain bikers who disturb the soils, are at risk of being exposed to airborne arthroconidia (asexual spores) of the pathogen. To reduce the risk of pathogen exposure for visitors, the Bureau of Land Management (BLM) plans to limit recreational activities to areas with a reduced pathogen presence...

A topic that has been less researched on, especially in Romania, is the identification of gender differences in oral health. The present scientific research used an online survey to assess the attitudes (dental beliefs survey-R/R-DBS), the values (oral health values scale/OHVS), the behaviours (dental neglect scale/DNS), and the literacy (oral health literacy scale/OHLS) related to oral health and to dental professional services in the case of a sample of 600 Romanian adults (Meanage = 30.84). The relation between the level of knowledge as a predictor of attitudes and values related to oral health was analysed by the means of a structural equation based on the partial least square method (PLS-SEM)...

OBJECTIVES: The purpose was to evaluate the characteristics of off-highway vehicle (OHV) crashes correlated with neurological injury and accident severity in the pediatric population in El Paso, Texas. METHODS: A retrospective review of 213 patients who were victims of an OHV crash attended at a regional Level I trauma center from 2012 to 2020 was performed. OHVs were defined as vehicles designated for use outside public roads. Neurological outcomes included any traumatic brain injury (TBI) or a brain hemorrhage/hematoma...

The Dental Neglect Scale (DNS) is a well-known measure for assessing behaviours and attitudes related to oral health. However, the factor inconsistency revealed by the literature involves further investigations. The study focuses on the validation of the DNS in the case of a sample of the adult population from Romania. In this regard, data were collected online from 872 adults (616 females and 256 males). DNS reliability was examined from the perspective of internal consistency. Convergent validity was performed by associating DNS with different scales from the oral health field...

BACKGROUND: To adapt and validate cross-culturally the Oral Health Values (OHVS) questionnaire to Portuguese language. METHODS: The OHVS questionnaire was culturally translated and adapted according to international guidelines. We enrolled 280 patients in a population-based epidemiological survey conducted at the Egas Moniz Dental Clinic (Almada, Portugal). The participants answered the Portuguese version of the OHVS (OHVS-PT), which is a 12-item scale with four-factor structure (Professional Dental Care, Appearance and Health, Flossing and Retaining Natural Teeth factor)...

Designing heterogeneous solid surface frustrated Lewis pair (ssFLP) catalyst for hydrogenation is a new challenge in catalysis and no research has been reported on the construction of ssFLP on boehmite (AlOOH) surfaces up to now as far as we know. Herein, AlOOH with a layer structure is prepared and it is found that the Lewis basic OHv site (one H removed from OH) and an adjacent Lewis acidic unsaturated Al site (Al3+ unsatur .) proximal to a surface OHv (OH vacancy) on AlOOH layers could form the ssFLP. The layered structure of AlOOH and its abundant OH defects over the surface result in a high concentration of OHv /Al3+ unsatur ...

Background and Objectives : Oral health values are an indicator of how people decide their priorities for oral health-an integral part of general health. The purpose of the study was the validation of the Oral Health Values Scale (OHVS), which measures the extent to which individuals invest in their oral health and which includes four factors: Professional dental care, Appearance, Flossing, and Retention of teeth. Materials and Methods : A cross-sectional study was conducted on a sample of adults ( n = 869; Mean age = 32...

Oxidative stress is the mainstream toxicological mechanism for the adverse health outcomes of ambient aerosols. However, our understanding of the crucial redox-active species affecting the oxidative potential of water-soluble aerosols (OPWS ) remains limited. In this study, the OPWS of PM2.5 in Beijing was measured using dithiothreitol (DTT) assay, including DTT consumption rate and ·OH formation rate. OPWS was more closely related to water-soluble organic compounds (WSOC) rather than transition metals. Laboratory simulations were conducted to investigate the effects of individual target species in the context of complex metal-organic interactions...

OBJECTIVES: The purpose of this study was to evaluate the protective effect of oral hydration volume to weight ratio (OHV/W) on contrast-induced acute kidney injury (CI-AKI) among patients with ST-elevation myocardial infarction (STEMI) following percutaneous coronary intervention (PCI). METHODS: A total of 754 patients with STEMI undergoing PCI were selected. Each patient was encouraged to drink as much water as possible 24 h after PCI. Total volume intake was recorded for all patients...

Purpose Chronic obstructive pulmonary disease (COPD) limits respiration, which may negatively impact airway safety during swallowing. It is unknown how differences in lung volume in COPD may alter swallowing physiology. This exploratory study aimed to determine how changes in lung volume impact swallow duration and coordination in persons with stable state COPD compared with older healthy volunteers (OHVs). Method Volunteers ≥ 45 years with COPD (VwCOPDs; n = 9) and OHVs ( n = 10) were prospectively recruited...

Intro: There is a wealth of research evidencing the high incidence of visual impairment (VI) and poor uptake of eye care services by adults with learning disabilities (LD). Despite this, very few authorities within England currently provide the additional support required by those with severe/profound LD (S/PLD). Method: By means of an initial funded pilot study, an unmet need was evidenced locally and a small service established to improve access to eye care for adults with S/PLD...

Polyols of palm olein/polyethylene terephthalate (PET) were synthesized by means of incorporating recycled PET from waste drinking bottles in different proportions into palm olein alkyd in the presence of ethylene glycol. The polyols were characterized by FTIR, and theirs hydroxyl value (OHV), acid value (AV) and viscosity were determined. The formulation of the polyurethane coating was carried out by dissolving the polyol in mixed solvent of cyclohexanone/tetrahydrofuran (THF) (4 : 1) followed by reacting 1 hydroxyl equivalent of the polyol with 1...

OBJECTIVES: Oral health values, the degree to which one places importance on or demonstrates investment in improving or maintaining one's dental status, are believed to vary across individuals. Research on this construct is in its infancy, so a new Oral Health Values Scale (OHVS) was developed and validated. The aim was to create a multidimensional measure of oral health values that could be used in future epidemiological or behavioural investigations involving determinants of dental treatment-seeking behaviour and/or oral health...

The development of bio-polyol from vegetable oil and its derivatives is gaining much interest from polyurethane industries and academia. In view of this, the availability of methyl oleate derived from palm oil, which is aimed at biodiesel production, provides an excellent feedstock to produce bio-polyol for polyurethane applications. In this recent study, response surface methodology (RSM) with a combination of central composite rotatable design (CCRD) was used to optimise the reaction parameters in order to obtain a maximised hydroxyl value (OHV)...

In this paper, we present the design and fabrication of a compact, modular optical high-voltage sensor (OHVS) based on fiber Bragg gratings (FBG) for a.c. distribution and transmission lines. The proposed OHVS is composed by a stack of piezoelectric transducers that transfer mechanical strain to a sensing FBG. A prototype was tested in the laboratory and showed a maximum linearity error of less than 3% of full-scale range (FSR) for input voltages up to ${14\,\,{\rm kV}_{\rm rms}}$14kVrms with a signal-to-noise ratio of 55 dB, allowing measurements with a resolution of less than 0...

Background: Oral hydration with water may be inexpensive and effective in the prevention of contrast-induced acute kidney injury (CI-AKI), but its efficacy among ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) remains unknown. Methods: This was a prospective, single-center, observational study. We consecutively enrolled 308 STEMI patients undergoing primary PCI. All patients drank unrestricted amounts of fluids freely, whose volume was recorded until 24 hours following primary PCI...
