The role of species and geography in the elemental profiles of farm-raised shrimp from Indonesia.

Elemental profiling is being explored as a traceability tool in many seafood products. However, the extent that elemental profiling can be used at finer geographical scales in cultured shrimp is unknown. Additionally, few studies have included multiple species in the same discriminant models, which would be useful in applications where one species is common, and the other is not.

Sources of variation in elemental profiles of whiteleg shrimp (Litopenaeus vannamei) and their potential effects on the accuracy of discriminant analysis.

Background: Elemental profiling is a tool that has been proposed to improve the traceability of seafood products. Small sources of variation can affect the outcome of elemental profiling and therefore pose to lower the overall accuracy of analyses. Here, we investigate two potential sources of variation through three experiments: laboratory variation (intra-, interlaboratory variation, and tissue matrix) and tissue variation.

Trace element concentrations in white leg shrimp from retail stores in the EU, UK, and USA and the ability to discern country of origin with classification models.

Shrimp are a globally traded aquaculture commodity that accounts for a large proportion of the monetary value of aquaculture. There are concerns among consumers about seafood labeling fraud and environmental sustainability. Therefore, the geographic origin of shrimp from retail stores was investigated with trace element profiling.

Usefulness of low-dose combined spinal epidural anesthesia for a woman with systemic lupus erythematosus, mechanical prosthesis in the mitral valve position, and worsening heart failure presenting for cesarean delivery.

A 31-year-old woman, gravida one, para zero, at 32 weeks, 4 days gestation, with a history of antiphospholipid antibody syndrome, mitral valve replacement requiring anticoagulation, chronic diastolic heart failure, and systemic lupus erythematous was admitted to the hospital for worsening cardiac decompensation with superimposed pneumonia. She was on warfarin for anticoagulation at the time of hospital admission and eventually started on an intravenous heparin infusion. Cesarean delivery was planned due to comorbidities and anticoagulation status.

Comparison of clinical and patient-reported outcomes with bilateral AcrySof toric or spherical control intraocular lenses.

Purpose: To compare clinical and patient-reported outcomes with bilateral implantation of AcrySof toric or spherical control (Alcon Laboratories Inc) intraocular lenses (IOLs).

Methods: Patients with cataract and corneal astigmatism who previously received either an AcrySof toric IOL or an AcrySof spherical control IOL were offered implantation of the same IOL in the fellow eye. Six-month assessments included visual acuity, refractive cylinder, spectacle use, and patient satisfaction.

Quality-of-life improvements in cataract patients with bilateral blue light-filtering intraocular lenses: clinical trial.

Purpose: To compare change in patient-reported vision-related and health-related functioning and quality of life (HRQOL) following bilateral implantation with a new blue light-filtering intraocular lens (IOL) with the results of a similar IOL that does not filter blue light.

Setting: Six clinical sites in the United States.

Methods: Patients were from 6 clinical sites in the United States that performed a high volume of cataract surgeries.
