Biomechanical Evaluation of the Accuracy in Radiographic Assessment of Femoral Component Migration Measurement after Total Hip Arthroplasty

Introduction: Implant subsidence is one criteria utilized to monitor for prosthesis loosening after total hip arthroplasty (THA) with initial implant subsidence assessment often done utilizing plain radiographs. The specific aim of this study was to identify the most reliable references when using plain radiographs to establish an image magnification with the goals being easy to use, inexpensive, reliable, and accurate. Methods: Two femoral stem implants (stem lengths: 127mm, 207mm) were utilized to simulate hemiarthroplasty of the hip with composite femurs. Different combinations of femoral stem distances from the radiographic film (ODD), source-detector differences (SDD), hip rotation, and hip flexion were elected. Standardized anterior-posterior pelvis for each parameter combination setup were taken. Radiographic measurements (head diameter, stem length, stem seating length) were undertaken five times by three examiners. Radiographic image magnification factors were generated from two references (head diameter and stem length). Radiograph measurement reproducibility and stem seating length errors using these magnification factors were evaluated. Results: High level of repeated measurements reliability was found for head diameter (99 ± 0%) and stem length (90 ± 7%) measurements, whereas seating length measurements were less reliable (76 ± 6%). Stem length error using the femoral head magnification factor yielded 11% accuracy. Stem seating length error using both magnification factors were not reliable (< 7% accuracy). All parameters, except SDD, showed significant effect on calibrated measurement error. Conclusions: Current methods of assessing implant subsidence after THA using plain radiographs are inaccurate or reliable. Clinicians should recognize these limitations and be cautious when diagnosing implant stability using plain radiographs alone

Peer relations and emotion regulation of children with emotional and behavioural difficulties with and without a developmental disorder

Children with emotional and behavioural difficulties (EBD) and those who also have developmental disorders, such as attention deficit hyperactivity disorder (ADHD) or autism spectrum disorder (ASD), can experience the same adverse consequences in their peer interactions and relationships. This present study compared the emotion regulation and peer relationships of children aged 8-12 years (M = 9.86 years, SD = 1.49) with EBD (N = 33) and children with EBD plus a diagnosed developmental disorder (N = 28). Multivariate analysis of variance (MANOVA) with Bonferroni adjusted alpha levels revealed no significant main effect for emotion regulation according to EBD status. There was, however, a multivariate main effect for sex, with females presenting with higher levels of negative emotional intensity (e. g., frustration, anger, aggression) than males. A second MANOVA revealed no significant main effect for peer relationships according to EBD status and sex. Significant correlations revealed that the EBD-only group experienced greater adverse peer interactions than the EBD-plus-developmental disorder group. These findings are important for educators and researchers involved in the development and evaluation of prevention and intervention programms for children with EBD

Sykepleie ved sepsis

Bakgrunn: Sepsis er en alvorlig sykdomstilstand som krever rask behandling. For at dette skal være mulig må sykepleiere bidra til å oppdage sepsis på et tidlig stadium ved bruk av ulike kartleggingsverktøy, samt observasjoner. Hensikt: Undersøke hvilken rolle sykepleiere har i tidlig oppdagelse av sepsis i akuttmottak, samt sammenligne ulike kartleggingsverktøy. Metode: I denne oppgaven analyserte vi fire kvantitative artikler etter Fribergs analysemodell for integrativ litteraturoversikt. Gjennom analysen har vi funnet tre hovedtemaer som er gjennomgående i artiklene. Det ene hovedtemaet deles inn i to underkategorier grunnet temaets store omfang. Vi benyttet oss av kvantitativ tilnærming. Resultat: Resultatet viser en mangel på et tilfredsstillende kartleggingsverktøy for identifisering av sepsis. Likevel kommer NEWS ut som det mest tilfredsstillende kartleggingsverktøyet sammenlagt basert på sensitivitet og spesifisitet. Sykepleiere spiller en stor rolle i identifisering og behandling av sepsis da de er i direkte kontakt med pasientene og kan derfor gjøre viktige observasjoner og målinger. Nøkkelord: Sepsis, kartleggingsverktøy, sykepleier, sykepleieres rolle, kunnskap, ferdighet, lovverk, etikk, tidlig oppdagelse, protokoller og behandling

Stimulant Medication and Reading Performance

The study examined the sustained effects of methylphenidate on reading performance in a sample of 42 boys, ages 8 to 11, with attention deficit-hyperactivity disorder (ADHD). Two subgroups were formed based on the presence or absence of co-occurring conduct disorders. Subjects were selected on the basis of their positive response to methylphenidate as determined in a series of original medication trials (Forness, Cantwell, Swanson, Hanna, & Youpa, 1991). For the purpose of this study, subjects were placed on their optimal dose of medication for a 6-week period and then tested on measures of oral reading and reading comprehension equivalent to those used in the original trials, retested after a week without medication (placebo), then tested again the following week after return to medication. Only the subgroup with conduct disorders responded, and this response was limited to reading comprehension improvement in only those subjects who also demonstrated improvement in oral reading on original trials. No response differences were found between subjects with or without learning disabilities.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68569/2/10.1177_002221949202500205.pd
