[Recommendations Not to do in rehabilitation and physical medicine: a compilation from different fields of intervention].

Introduction And Objective: Certain medical practices, both diagnostic and therapeutic, that have not been proven to be effective and do not add value to healthcare, are not uncommon. The aim of this document is to provide a list of «Not to do» recommendations in the medical specialty of Physical Medicine and Rehabilitation.

Material And Method: For the development of this project, which is coordinated by the Vocalía de Sociedades Filiales, Sociedades Autonómicas y Grupos de Trabajo de la Sociedad Española de Rehabilitación (SERMEF), specific recommendations are requested from Grupos de Trabajo and Sociedades Filiales of each specific field of Physical Medicine and Rehabilitation, as experts in the corresponding intervention areas.

A Review of Backward Higher-Order Conditioning: Implications for a Pavlovian Conditioning Analysis of Stimulus Equivalence.

Stimulus equivalence (SE) is demonstrated when participants exposed to conditional discrimination training pass tests for reflexivity, symmetry, transitivity, and equivalence (symmetry combined with transitivity). Most theorists attribute the origin of SE to operant processes, but some argue that it results from Pavlovian conditioning. Symmetry is problematic for the latter hypothesis because it seems to require excitatory backward conditioning.

The Problem of Class Breakdown in Sidman's (1994, 2000) Theory about the Origin of Stimulus Equivalence.

Sidman (1994, 2000) hypothesized that equivalence relations are a direct outcome of reinforcement contingencies. This theory is problematic because contingencies do not always result in equivalence. Sidman proposed that equivalence relations may conflict with analytic units, the other outcome of contingencies (e.

Rate matching, probability matching, and optimization in concurrent ratio schedules.

Much research has documented rate matching in concurrent variable-interval schedules, but comparatively little research has examined performance in concurrent variable-ratio schedules, except in discrete-trials procedures that sometimes produce probability matching. One should expect that the two types of schedule would result in different performances, because ratio schedules cannot improve with time the way interval schedules do; ratio schedules lack the temporal dynamics of interval schedules. The present experiment exposed rats to concurrent variable-ratio schedules.

Equivalence class analysis of responding consistent with the relational frame of opposition.

We replicated and extended studies showing that contextual cues for matching stimuli from 2 separate equivalence classes control the same derived relations as contextual cues for opposition frames in RFT studies. We conducted 2 experiments with 6 college students. In Phase 1, they received training in a conditional discrimination AB.

Analysis of apparent demonstrations of responding in accordance with relational frames of sameness and opposition.

We evaluated whether contextual control over equivalence and nonequivalence and responding by exclusion can explain the outcomes of relational frame theory (RFT) studies on sameness and opposition relations. We trained nine college students to maintain and reverse conditional discriminations with X1 and X2 as contextual stimuli. In Experiment 1, X1 and X2 controlled derived stimulus relations (DSR) analogous to those controlled by Same and Opposite in RFT studies.

Spontaneously hypertensive (SHR) rats choose more impulsively than Wistar-Kyoto (WKY) rats on a delay discounting task.

Indications of Attention Deficit Hyperactivity Disorder (ADHD) in the spontaneously hypertensive rat (SHR) are not consistent across different tests of impulsivity, questioning the SHR's validity as a rodent model of ADHD. This study used a concurrent-chains procedure to examine possible differences in impulsive choice between SHRs and control-normotensive Wistar Kyoto (WKY) rats. The aim was to extend the generality of findings showing regularities between the hyperbolic-decay model and the generalized matching law fitting delay discounting data from nonhuman animals.

Contextual control over equivalence and nonequivalence explains apparent arbitrary applicable relational responding in accordance with sameness and opposition.

We evaluated whether contextual control over equivalence and nonequivalence (i.e., selecting comparisons equivalent to the samples in the presence of a contextual cue, and excluding the selection of comparisons equivalent to the samples in the presence of another contextual cue) can account for apparent arbitrarily applicable relational responding (AARR) in accordance with the frames of sameness and opposition, as defined in relational frame theory (RFT).

Plasma levels of trastuzumab in gastric cancer: Case report.

Introduction The use of trastuzumab with a fluoropyrimidine and platinum compound is currently the standard first-line treatment of patients with metastatic HER2-positive gastric cancer, but it appears that serum levels of trastuzumab determine the clinical effectiveness of this treatment, affecting progression-free survival and overall survival. Case report We report the case of a patient with metastatic HER2-positivegastric cancer, receiving XELOX (fluoropyrimidine and oxaliplatin) plus trastuzumab at standard doses, who presented sub-therapeutic serum levels during the first two treatment cycles and rapid disease progression (progression-free survival = 5.6 months).

A long-term study of the impulsive choices of Lewis and Fischer 344 rats.

Contemporary analyses of choice were implemented to analyze the acquisition and maintenance of response allocation in Lewis (LEW) and Fischer 344 (F344) rats. A concurrent-chains procedure varied the delay to the larger reinforcer (0.1, 5, 10, 20, 40, and 80 s).

Derived control by compound and single stimuli in a matching-to-sample task in children.

A matching-to-sample procedure was used to investigate whether 9-year-old children would demonstrate the emergence of a derived compound-sample conditional discrimination following training in four interrelated single-sample conditional discriminations and vice versa, as adults did in previous studies. In Experiment 1, three out of three children demonstrated the emergence of a compound-sample conditional discrimination following training in four single-sample conditional discriminations. In Experiment 2, two out of three children acquired a compound-sample conditional discrimination and they demonstrated the emergence of four single-sample conditional discriminations; one of them did so only after being exposed to a remediation training and testing procedure.

Common control by compound samples in conditional discriminations.

We tested whether teaching control by single stimulus samples in conditional discriminations would result in common control of two-stimuli compound samples, and vice versa. In Experiment 1, 5 participants were first taught four single-sample conditional discriminations. The first conditional discrimination was as follows: given sample stimulus P1, select comparison stimulus A1 and not A2; given sample P2 select comparison A2 and not A1.

[Neonatal sepsis caused by Streptococcus agalactiae. What should be done?].

Objective: Within the common pathogenic flora responsible for neonatal sepsis, streptococci group B (SGB) is the most frequently found etiological agent. The fact that it is a frequent colonizer of the female perigenital area has resulted in a whole host of detection and eradication strategies via preventative measures applied to the pregnant woman to eliminate vertical transmission to the newborn.

Patients And Methods: We present a revision of SGB sepsis and our protocol based on the intrapartum treatment of those pregnant women with risk factors and the study in the newborn at risk of infection with early detection of particles of Latex in urine for SGB (Slidex Strepto B bioMerieux), as well as the customary analytical and bacteriological tests.
