Abutment contours, position, tissue thickness, and volume are all key parameters for the successful restoration of implants in the aesthetic zone. This is particularly true for patients with high smile lines and high aesthetic expectations. This narrative review will provide a synopsis of the known science of implant abutments and peri-implant tissues in this area and cover specialised techniques, materials, and protocols to improve outcomes with increased predictability.

Multimodal critical discourse analysis is a dynamic approach to qualitative data analysis that expands critical discourse analysis to include multiple communicative modes-such as images, graphics, video, and sound/music-into the semiotic analysis of ideology and power relations within contemporary forms of communication. We reflect on the potential of multimodal critical discourse analysis to be combined with arts-based health research as an analytic method to deconstruct discourses that shape the health and well-being of marginalized communities. Specifically, we frame this potential within our research about men's body image based a project using cellphilming and the deconstruction of cis-heteronormative and related ideologies.

Introduction: Early caregiving interactions and experiences profoundly shape a child's brain development. The American Academy of Pediatrics (AAP) recently advocated for a public-health approach to promoting safe, stable, nurturing relationships that is "founded on universal primary preventions", including consistent messaging on fostering family resilience, nurturing connections, and positive childhood experiences. Hospitals have unique access to families with children ages 0-5 and therefore play a key role in supporting these early experiences.

There is a long history of linking the perceptions of temperature and color (the "Hue-heat hypothesis"): red (R) and yellow (Y) are often considered warm, whereas blue (B) and green (G) are cool. Past studies, however, have largely used relatively broad-band light at a fixed intensity to test these relations. We tested whether increasing the intensity of highly saturated primary colors would lead to a concomitant change in the perceived temperature of those colors.

Leukotriene B4 (LTB4) is an inflammatory lipid produced in response to pathogens that is critical for initiating the inflammatory cascade needed to control infection. However, during plague, Yersinia pestis inhibits the timely synthesis of LTB4 and subsequent inflammation. Using bacterial mutants, we previously determined that Y.

Multiple sclerosis (MS) is a devastating autoimmune disease that leads to profound disability. This disability arises from the stochastic, regional loss of myelin-the insulating sheath surrounding neurons-in the central nervous system (CNS). The demyelinated regions are dominated by the brain's resident macrophages: microglia.

Leukotriene B4 (LTB) is critical for initiating the inflammatory cascade in response to infection. However, colonizes the host by inhibiting the timely synthesis of LTB and inflammation. Here, we show that the bacterial type 3 secretion system (T3SS) is the primary pathogen associated molecular pattern (PAMP) responsible for LTB production by leukocytes in response to and , but synthesis is inhibited by the Yop effectors during interactions.

Motivation: Data is increasingly used for improvement and research in public health, especially administrative data such as that collected in electronic health records. Patients enter and exit these typically open-cohort datasets non-uniformly; this can render simple questions about incidence and prevalence time-consuming and with unnecessary variation between analyses. We therefore developed methods to automate analysis of incidence and prevalence in open cohort datasets, to improve transparency, productivity and reproducibility of analyses.

Background: Cerebrospinal fluid leak after endoscopic skull base surgery remains a significant complication. Several investigators have suggested Hydroset cranioplasty to reduce leak rates. We investigated our early experience with Hydroset and compared the rate of nasal complications and CSF leak rates with case-controlled historic controls.

Blue light-filtering (BLF) intraocular lenses (IOLs) are designed to mimic the healthy natural adult crystalline lens. Studies that evaluated the relative merit of ultraviolet-only IOL design (ie, blocking wavelengths <400 nm) versus BLF IOL design (ie, filtering wavelengths ~400-475 nm in addition to blocking wavelengths <400 nm) on protection and function of the visual system suggest that neither design had a deleterious impact on visual acuity or contrast sensitivity. A BLF design may reduce some aspects of glare, such as veiling and photostress.

Puppy play is a kink activity, in which people dress as, take on the role of, and mimic the physical and emotional behaviours of young canines or pups. We explore how the pup identity, depicted in cellphilms by queer men who are part of the pup community, influences men's body image perceptions using multimodal critical discourse analysis. Participants expressed feelings of dissonance, shame, and self-rejection when viewing themselves as humans, but conveyed excitement, pleasure, and self-celebration when viewing themselves as pups.

The health impacts of intimate partner violence against women and childhood sexual abuse are not fully understood. Here we conducted a systematic review by comprehensively searching seven electronic databases for literature on intimate partner violence-associated and childhood sexual abuse-associated health effects. Following the burden of proof methodology, we evaluated the evidence strength linking intimate partner violence and/or childhood sexual abuse to health outcomes supported by at least three studies.

Adolescent development is characterized by an improvement in cognitive abilities, such as working memory. Neurophysiological recordings in a nonhuman primate model of adolescence have revealed changes in neural activity that mirror improvement in behavior, including higher firing rate during the delay intervals of working memory tasks. The laminar distribution of these changes is unknown.

In this study we assessed the neural correlates of functional vision while varying patterns of light filtration. Four filter conditions used relatively flat filtering across the visible spectrum while one filter was a step filter that selectively absorbed violet light (wavelengths below about 415 nm). Neural effects were quantified by measuring the BOLD response ((T2*-based fMRI) while subjects performed a challenging visual task (judging gap direction in Landolt Cs that randomly varied in size).
