Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger retailers. In 2014, prices were measured for 15 staple foods during store visits in 140 smaller stores (corner stores, gas-marts, dollar stores, and pharmacies) in Minneapolis/St...

PURPOSE: Evaluation and surgical management for adult spinal deformity (ASD) patients varies between health care providers. The purpose of this study is to identify appropriateness of specific approaches and management strategies for the treatment of ASD. METHODS: From January to July 2015, the AOSpine Knowledge Deformity Forum performed a modified Delphi survey where 53 experienced deformity surgeons from 24 countries, rated the appropriateness of management strategies for multiple ASD clinical scenarios...

PURPOSE: To evaluate the safety and efficacy of a superelastic shape-memory alloy (SNT) rod used in the treatment of adolescent idiopathic scoliosis (AIS). METHODS: AIS Patients with Lenke 1 curves undergoing fusion surgery were randomized (1:1) at the time of surgery to receive either the SNT or a conventional titanium alloy (CTA) rod. Radiographs were obtained preoperatively and postoperatively up to 5 years of follow-up. Parameters assessed included coronal and sagittal Cobb angles, and overall truncal and shoulder balance...

Silicon (Si) is taken up from the soil as monosilicic acid by plant roots, transported to leaves and deposited as phytoliths, amorphous silica (SiO2) bodies, which are a key component of anti-herbivore defense in grasses. Silicon transporters have been identified in many plant species, but the mechanisms underpinning Si transport remain poorly understood. Specifically, the extent to which Si uptake is a passive process, driven primarily by transpiration, or has both passive and active components remains disputed...

BACKGROUND: The correlation between implant density and deformity correction has not yet led to a precise conclusion in adolescent idiopathic scoliosis (AIS). The aim of this study was to evaluate the effects of low density (LD) and high density (HD) pedicle screw instrumentation in terms of the clinical, radiological and Scoliosis Research Society (SRS)-22 outcomes in Lenke 1 AIS. METHODS: We retrospectively reviewed 62 consecutive Lenke 1 AIS patients who underwent posterior spinal arthrodesis using all-pedicle screw instrumentation with a minimum follow-up of 24 months...

STUDY DESIGN: Prospective cohort study OBJECTIVE.: To prospectively compare radiographic, perioperative and functional outcomes between anterior spinal instrumented fusion (ASIF) and posterior spinal instrumented fusion (PSIF) in Lenke 5C curves. SUMMARY OF BACKGROUND DATA: Historically, ASIF has been the treatment of choice for treatment of thoracolumbar adolescent idiopathic scoliosis (AIS). More recently, PSIF has gained popularity for its ease, versatility and amount of correction achieved...

BACKGROUND: Describing the morphologic features of the thoracic pedicle in patients with adolescent idiopathic scoliosis is necessary for placement of pedicle screws. Previous studies showed inadequate reliability owing to small sample size and heterogeneity of the patients surveyed. QUESTIONS/PURPOSES: To use CT scans (1) to describe the morphologic features of 2718 thoracic pedicles from 60 female patients with Lenke Type 1 adolescent idiopathic scoliosis and 60 age-, sex-, and height-matched controls; and (2) to classify the pedicles in three types based on pedicle width and analyze the distribution of each type...

Intervertebral disc diseases (IVDDs) form a group of a vertebral column disorders affecting a large number of people worldwide. It is estimated that approximately 30% of individuals at the age of 35 and approximately 90% of individuals at the age of 60 and above will have some form of disc-affecting pathological changes leading to disc herniation, prolapse and degeneration as well as discogenic pain. Here, we aimed to establish the origins and neurochemical characteristics of porcine intervertebral disc sympathetic innervation involved in pain signalling in IVDD patients...

We summarize up-to-date diagnostic and treatment of infectious keratitis using literature data and some clinical examples. In the clinical practice, most commonly bacterial, herpetic, mycotic and acanthamoeba keratitis occur. Beside slitlamp examination, for diagnostic purpose, we analyse corneal sensitivity, perform in vivo confocal microscopy, polymerase-chain-reaction (PCR), in vitro culture and histological examination of the corneal sample. As conservative treatment we use primarily topical moxifloxacin or cephasolin with fortified tobramycin or gentamycin in bacterial, topical antiviral gel (in some cases in combination with systemic antiviral treatment) in part in combination with topical corticosteroids in herpetic, voriconasole or amphotericin-B in mycotic, and topical-triple-therapy (diamidine, biguanid and antibiotics) in acanthamoeba keratitis...

BACKGROUND CONTEXT: Selection of UIV for Lenke 5 and 6 curves remains debatable, and several authors had described different selection strategies. OBJECTIVE: This study analyzed the flexibility of the unfused thoracic segments above the 'potential upper instrumented vertebrae (UIV)' (T1 to T12) and its compensatory ability in Lenke 5 and 6 curves using supine side bending (SSB) radiographs. STUDY DESIGN: Retrospective study PATIENT SAMPLE: 100 patients OUTCOME MEASURES: The ability of the unfused thoracic segments above the 'potential upper instrumented vertebrae (UIV)' i...

STUDY DESIGN: Retrospective review of a prospective Adolescent Idiopathic Scoliosis (AIS) registry OBJECTIVE.: To study the evolution of the operative approach, outcomes and complication rates in AIS surgery over the past 20 years. METHODS: 1819 AIS patients (1995-2013) with 2-year F/U were studied. Operative approach, perioperative parameters, major complication rates, and SRS outcomes were assessed. Linear regression was used to assess the trend of changes over 5-year quartiles...

Antibody therapy constitutes a major advance in the treatment of B-cell precursor acute lymphoblastic leukemia (BCP-ALL). To evaluate the efficacy and the mechanisms of action of CD19 monoclonal antibody therapy in pediatric BCP-ALL, an Fc engineered CD19 antibody carrying the S239D/I332E mutation for improved effector cell recruitment (CD19-DE) was tested. Patient derived xenografts (PDX) of pediatric MLL-rearranged ALL were established in NOD.Cg-Prkdc(scid) Il2rg(tm1Wjl)/SzJ (NSG) mice. Antibody CD19-DE was efficient in prolonging the survival of NSG mice in a minimal residual disease (MRD) model...

BACKGROUND: For patients with adolescent idiopathic scoliosis, shoulder balance influences their treatment satisfaction and psychological well-being. Several parameters are known to affect postoperative shoulder balance, but few prognostic models are as yet available. PURPOSE: This study aimed to identify independent predictive factors that can be used to assess preoperatively which patients are at risk of postoperative shoulder elevation, and to build a linear prediction model...

A recent epidemiology study revealed that prevalence of keratoconus was much higher than previously assumed. Therefore, it is no longer deemed an "orphan disease", as it has a relevant socioeconomic impact on the healthcare system. One of the most important risk factors for developing keratoconus is chronic eye rubbing which, apart from other known risk factors such as atopy or Down's syndrome, is the only modifiable factor. Informing the patient and offering behavior modifying therapies seems to be essential...

STUDY DESIGN: Retrospective study. OBJECTIVE: To compare 2 methods of selecting the lowest instrumented vertebra (LIV) on the rates of revision surgery for distal junctional kyphosis (DJK) following treatment for Scheuermann's kyphosis (SK). METHODS: A retrospective review of patients who have undergone surgical treatment for SK was performed. Forty-four patients were divided into 2 groups based on intervention: Group 1 (n = 26) included patients who had an LIV distal to or at the sagittal stable vertebrae (SSV), and Group 2 (n = 18) included patients who had an LIV proximal to the SSV...
