BACKGROUND: Total hip replacements (THRs) are the sixth most common surgical procedure performed in the USA. Readmission rates are estimated at between 4.0 and 10.9%, and mean costs are between $10,000 and $19,000. Readmissions are influenced by the quality of care received. We sought to examine differences in readmissions by insurance payer, race and ethnicity, and income status. METHODS: We analyzed all THRs from 2007 to 2011 in California, Florida, and New York from the State Inpatient Databases, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality...

BACKGROUND: Scleral buckling is an established modality of treating retinal detachment. Being an external implant the buckle may be prone to infections. We report such a case with a delayed presentation and a rare etiology. CASE PRESENTATION: A 45 year old male presented with redness, foreign body sensation and discharge for one month in his right eye. The patient had undergone a retinal detachment surgery elsewhere 14 years back without any visual gain. Right eye demonstrated no perception of light and the best corrected visual acuity in the left eye was 6/6, N6...

OBJECTIVES: Baseline retinal examination has long been recommended at hydroxychloroquine (HCQ) initiation, but it is unknown how well this guideline is followed. We investigated baseline eye examinations among U.S. Medicaid SLE patients initiating HCQ. METHODS: Using billing codes, we identified SLE patients aged 18-65 enrolled in Medicaid, residing in the 29 most populated U.S. states from 2000-2010. New HCQ users were identified by filling a prescription, with none in the preceding 12 months...

INTRODUCTION: Crotonaldehyde is an α,β-unsaturated carbonyl compound that is a potent eye, respiratory, and skin irritant. Crotonaldehyde is a major constituent of tobacco smoke and its exposure can be quantified using its urinary metabolite N-acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (HPMM). A large-scale biomonitoring study is needed to determine HPMM levels, as a measure of crotonaldehyde exposure, in the general U.S. POPULATION: HASH(0x4c73848) MATERIALS AND METHODS: Urine samples were obtained as part of the National Health and Nutrition Examination Survey 2005-2006 and 2011-2012 from participants who were at least six-years-old (N = 4692)...

Two experiments are presented that explore online counterfactual processing in autism spectrum disorder (ASD) using eye-tracking. Participants' eye movements were tracked while they read factual and counterfactual sentences in an anomaly detection task. In Experiment 1, the sentences depicted everyday counterfactual situations (e.g., If Joanne had remembered her umbrella, her hair would have been dry/wet when she arrived home). Sentences in Experiment 2 depicted counterfactual versions of real world events (e...

Background: To evaluate macular pigment optical density (MPOD) and to identify its determinants in a sample of Brazilian individuals. Methods: This was a cross-sectional study. One hundred three healthy individuals had both eyes photographed using a Visucam 500 digital fundus camera (Carl Zeiss Meditec, Jena, Germany) in combination with the MPOD module. Four variables were obtained: maximum MPOD, mean MPOD, MPOD volume, and MPOD area. Demographic data and information on lifestyle habits were also collected...

OBJECTIVE: To describe the ocular anatomy of the black pacu (Colossoma macropomum), a freshwater teleost fish of the Amazon River basin, including an unusual choroid laden with adipose tissue. PROCEDURES: Three adult black pacu were anesthetized and examined clinically and with ocular ultrasonography, then euthanized. Three fish were euthanized and their heads imaged immediately postmortem using computed tomography. One fish was euthanized and its exenterated eyes imaged by high-resolution magnetic resonance imaging...

Retinal inflammation plays a key role in the progression of age-related macular degeneration (AMD), a condition that leads to loss of central vision. The deposition of the acute phase pentraxin C-reactive protein (CRP) in the macula activates the complement system, thereby contributing to dysregulated inflammation. The complement protein factor H (FH) can bind CRP and down-regulate an inflammatory response. However, it is not known whether a truncated form of FH, called factor H-like protein 1 (FHL-1), which plays a significant regulatory role in the eye, also interacts with CRP...

OBJECTIVE: To assess the relationship between sociodemographic variables (including race, age, and insurance coverage) and preoperative best-corrected visual acuity (BCVA) at the time of first-eye cataract surgery. METHODS: Single-center retrospective chart review study at Shiley Eye Institute, University of California, San Diego (UCSD). Medical record data from 600 patients were collected from the appointment immediately preceding cataract surgery, including BCVA in the operated eye converted to the logarithmic minimal angle of resolution (logMAR), insurance coverage, race, sex, age, body mass index, smoking status (including pack years), systemic and ocular comorbidities, and ocular surgical history...

Petroleuciscus ninae sp. nov. is described from the Büyük Menderes River drainage. The new species is distinguished by having a black lateral stripe from head to base of caudal fin, stripe distinct anteriorly and posteriorly, wider than eye diameter; numerous black pigments on anal-fin rays; body depth at dorsal-fin origin 27-30% standard length (LS ); head width at posterior margin of eye 16-19% LS ; and eye diameter smaller than snout length. Petroleuciscus ninae is also distinguished from other species in adjacent waters by having six fixed diagnostic nucleotide substitutions in the mitochondrial DNA coI barcode region...

PURPOSE: Optical treatment alone can improve visual acuity (VA) in children with amblyopia, thus clinical trials investigating additional amblyopia therapies (such as patching or videogames) for children require a preceding optical treatment phase. Emerging therapies for adult patients are entering clinical trials. It is unknown whether optical treatment is effective for adults with amblyopia and whether an optical correction phase is required for trials involving adults. METHODS: We examined participants who underwent optical treatment in the Binocular Treatment for Amblyopia using Videogames (BRAVO) clinical trial (ANZCTR ID: ACTRN12613001004752)...

Silver nitrate has been adopted for medical use as a disinfectant for eye disease and burned wounds. In dentistry, it is an active ingredient of Howe's solution used to prevent and arrest dental caries. While medical use of silver nitrate as a disinfectant became subsidiary with the discovery of antibiotics, its use in caries treatment also diminished with the use of fluoride in caries prevention. Since then, fluoride agents, particularly sodium fluoride, have gained popularity in caries prevention. However, caries is an infection caused by cariogenic bacteria, which demineralise enamel and dentine...

At high temperature (greater than 40°C) endotherms experience reduced passive heat dissipation (radiation, conduction and convection) and increased reliance on evaporative heat loss. High temperatures challenge flying birds due to heat produced by wing muscles. Hummingbirds depend on flight for foraging, yet inhabit hot regions. We used infrared thermography to explore how lower passive heat dissipation during flight impacts body-heat management in broad-billed (Cynanthus latirostris, 3.0 g), black-chinned (Archilochus alexandri, 3...
