External validation of the CHEDDAR score for suspected pulmonary embolism in patients with SARS-CoV-2 infection in an independent cohort.

The accuracy of the classic scores that help stratify the pretest clinical probability of pulmonary embolism (PE) in SARS-CoV-2 infection (COVID-19) is low. Therefore, to estimate the risk of PE in these patients, a new set of guidelines must be established. The recently published CHEDDAR score proposes a new diagnostic strategy to reduce the use of computed tomography pulmonary angiography (CTPA) in non-critically ill SARS-COV-2 patients with suspected PE. According to the nomogram, patients are segregated into low-risk (< 182 points) or high-risk (≥ 182 points) based on the best cut-off value to discard PE in the original cohort. We aimed to externally validate this diagnostic strategy in an independent cohort. We analyzed data from two retrospective cohorts of hospitalized non-critically ill COVID-19 patients who underwent a CTPA due to suspicion for PE. CHEDDAR score was applied. As per the CHEDDAR nomogram, patients were classified as having a low or high clinical pre-test probability. Of the 270 patients included, 69 (25.5%) had PE. Applying the CHEDDAR score, 182 (67.4%) patients could have had PE excluded without imaging. Among 58 patients classified as having high clinical pre-test probability, 39 (67.2%) had PE. Sensitivity, specificity, positive and negative predictive values, and AUC were 56%, 90%, 67%, 85%, and 0.783 (95% CI 0.71-0.85), respectively. We provide external validation of the CHEDDAR score in an independent cohort. Even though the CHEDDAR score showed good discrimination capacity, caution is required in patients classified as having low clinical pre-test probability with a D-dimer value > 3000 ng/mL, and a RALE score ≥ 4.

Needed independent and dependent variables in multi-element behavior support plans addressing severe behavior problems.

Ethically , behavior analysts are required to use the least aversive and restrictive procedures capable of managing behaviors of concern. This article introduces and discusses a multi-element paradigm for devising support plans that include ecological, positive programming, and focused-support proactive strategies for reducing the frequency of problem behavior occurrence. It also includes reactive strategies, i.e., separate independent variables. In this paradigm, reactive strategies are aimed solely at getting rapid, safe control over the incident, thereby reducing measured and quantified episodic severity. Behavior analysts who publish in mainstream behavioral journals do not always make it explicit how they, in fact, successfully employed non-aversive reactive procedures to achieve rapid/safe control over the severity of a behavioral incident. Three examples of published studies in the behavioral literature which successfully, though only implicitly, used non-aversive reactive strategies (NARS) to reduce the severity of the behaviors of concern are described. The multi-element paradigm discussed in the present article is illustrated by the support plans that address the challenging behavior of three children in a pre-school setting, using both proactive and reactive strategies. Reactive strategies were used for the purpose of reducing episodic severity (ES) and proactive strategies were aimed at reducing the frequency of occurrence. Following a comprehensive functional analysis and assessment (CFA) and the implementation of a multi-element behavior support (MEBS) plan, results show successful outcomes without the need for any aversive or restrictive procedures. When addressing severe behaviors of concern, in addition to reducing behavioral occurrence, safety should also be improved by reducing ES as a measured outcome and as a function of the reactive strategies employed, including in many cases, the use of strategic capitulation, i.e., providing the identified reinforcer for the target behavior.

Sexual dysfunctions in people with first-episode psychosis assessed according to a gender perspective.

AIM: Patients with chronic mental disorders often can suffer from sexual dysfunction. Nevertheless, the sexual functioning of new patients with first-episode psychosis has been little explored. The aim of this study was to investigate gender differences in sexual functioning in people with first-episode psychosis. METHODS: A group of 40 males and 37 females with first-episode psychosis took part in the research. We administered a psychiatric protocol composed of the PANSS, UKU and SCID-DSM-IV diagnosis. RESULTS: We found that the 42.5% of the male group had sexual dysfunctions while the percentage of the female group was 37.8%. The correlation between sexual dysfunctions and psychopathology did not reveal any association in males. However, in females, general psychopathology and positive symptoms are linked to the alteration of vaginal lubrication: (r=0.547; p=0.003) and (r=0.485; p=0.011), although orgasm alteration was also associated with general psychopathology (r=0.500; p=0.013). Moreover, we found a relation between the alteration of vaginal lubrication with depression(r=0.627; p<0.0001) and disorder of volition (r=0.600; p<0.001). DISCUSSION AND CONCLUSIONS: These data suggest that the association between sexual dysfunctions and psychopathology regarded only women. Therefore, during the taking charge of patients it is fundamental to consider the gender-specific relationship between psychopathology and sexual problems.

Gender differences in incipient psychosis

Background and Objectives: To describe gender differences in a group of patients with first-episode psychotic in different aspects: socio-demographic features, characteristics of the phases prior to disease onset (premorbid and prodromic periods), clinical manifestation of psychotic symptoms and possible corresponding cognitive alterations after disease onset, using the age at onset of first psychotic episode as a control variable. Methods: Longitudinal study of 53 consecutive cases with a first psychotic episode. Inclusion criteria: two or more psychotic symptoms; age between 7 to 65 years old; first consultation to the medical center of study; less than 6 months since the first contact to the medical service; and less than a year of symptoms’ evolution. The methodologic assessment includes: a socio-demographic questionnaire and an extensive battery of tests to asses premorbid/prodromic, clinical and cognitive characteristics. We perform mean differences tests to analyze continuous variables (non-parametric U-Mann-Whitney and t-Student test) and chi-square test for categorical variables (SPSS 16.0).Results: In the group of patients under 18 years, men showed higher scores in adjustment premorbid (U = 54.0, p = 0.050), more neurological soft signs (U = 31.0 p = 0.003), more negative psychotic symptoms (U = 48.5, p = 0.051) and worse insight (U = 30.0, p = 0.003)than women (after 8 weeks of psychotic episode onset).Conclusions: We found gender differences in most of the variables analyzed when age at onset was controlled. These differences should be taken into account to learn more about the different types of onset of the disease, its prevention and possible improvements in therapeutic approach. Our findings suggest that younger men with an earlier onset of psychotic episode have more alterations in the stages prior to the onset of the disease supporting the neurodevelopmental hypothesis for gender differences (AU)
