Objectives: Perceived Social Status (PSS) is a measure of cumulative socioeconomic circumstances that takes perceived self-control into account. It is hypothesized to better capture social class compared to socioeconomic status (SES) measures (i.e., education, occupation, and income). This study examined the association between PSS and dental utilization, comparing the strength of associations between dental utilization and PSS and SES measures among a low-income adult Medicaid population.
Methods: A cross-sectional survey was administered to a random sample of low-income adults in Iowa, United States with Medicaid dental insurance (N = 18,000) in the spring of 2018. Respondents were asked about PSS, dental utilization, and demographics. A set of multivariable logistic regression models examined the relative effects of PSS and SES measures on dental utilization, controlling for age, sex, health literacy, whether the respondent was aware they had dental insurance, transportation, and perceived need of dental care.
Results: The adjusted response rate was 25%, with a final sample size of 2252. Mean PSS (range 1-10) was 5.3 (SD 1.9). PSS was significantly associated with dental utilization (OR = 1.11; CI = 1.05, 1.18) when adjusting for control variables, whereas other SES measures-education, employment, and income-were not.
Conclusions: PSS demonstrated a small positive association with dental utilization. Results support the relative importance of PSS, in addition to SES measures, as PSS may capture aspects of social class that SES measures do not. Results suggest the need for future research to consider the effects of PSS on oral health outcomes and behaviors.

Background: Dental care before pregnancy is critical for preventing poor oral health, which is associated with adverse pregnancy outcomes. People with low incomes, however, may face insurance-related barriers to obtaining dental care. Medicaid expansion under the Affordable Care Act increased access to dental care utilization among adults with low incomes.

While most dentate non-mammalian vertebrates possess simple conical teeth, some demonstrate complex tooth shapes. Lake Malawi cichlid fishes are an extreme example of this, exhibiting a myriad of tooth shapes driven by an ecologically derived rapid evolution of closely related but distinct species. Tooth shape in mammals is generally considered to be established by signaling centers called primary and secondary enamel knots, which are not believed to be present in non-mammalian vertebrates.

Background: Chest computed tomography (CT) is a valuable tool for diagnosing and predicting the severity of coronavirus disease 2019 (COVID-19) and assessing extrapulmonary organs. Reduced muscle mass and visceral fat accumulation are important features of a body composition phenotype in which obesity and muscle loss coexist, but their relationship with COVID-19 outcomes remains unclear. In this study, we aimed to investigate the association between the erector spinae muscle (ESM) to epicardial adipose tissue (EAT) ratio (ESM/EAT) on chest CT and disease severity in patients with COVID-19.

Background: Nivolumab paved a new way in the treatment of patients with recurrent or metastatic (RM) head and neck squamous cell carcinoma (RM-HNSCC). However, the limited rates of long-term survivors (< 20%) demand a robust prognostic biomarker. This nationwide multi-centric prospective study aimed to identify a plasma exosome (PEX) mRNA signature, which serves as a companion diagnostic of nivolumab and provides a biological clue to develop effective therapies for a majority of non-survivors.

Background: People experiencing tooth loss need dental prostheses to preserve the integrity of their oral structures and replace the missing teeth. Patient-related outcome measures (PROMs) for perceived barriers to prosthodontics treatment are scarce in the literature.
Aims: The aim of this study was to develop a comprehensive scale to identify and measure barriers to prosthodontic treatment as perceived by partially edentulous patients.
