The Strongest Correlates of PTSD for Firefighters: Number,Recency, Frequency,or Perceived Threat of Traumatic Events?

Firefighters experience a wide range of traumatic events while on duty and are at risk to develop psychopathology and posttraumatic stress disorder (PTSD). According to cognitive models, the person's interpretation of the traumatic event is responsible for the development of PTSD rather than the traumatic event itself. This cross‐sectional study aimed to explore the contribution of perceived threat to explain PTSD symptoms in Portuguese firefighters, after adjusting for potential confounding factors. A sample of 397 firefighters completed self‐report measures of exposure to traumatic events, psychopathology, and PTSD. Perceived threat explained unique variance in PTSD symptoms, R² = .40, ΔR² = .02, F(10, 367) = 24.55, p < .001, Cohen's f² =.03, after adjusting for psychopathology, number, recency, and frequency of the events, and other potential confounding variables. The association between psychopathology and PTSD was also moderated by perceived threat, R² = .43, ΔR² = .03, F(11, 366) = 25.33, p < .001, Cohen's f² =.05. Firefighters may benefit from interventions that focus on perceived threat to prevent PTSD symptoms.     

Vasculitis associated with anti-neutrophil cytoplasmic autoantibodies in rheumatoid arthritis. Report of a case of microscopic polyangiitis and another case of Wegener's granulomatosis

Vasculitis is an uncommon complication of rheumatoid arthritis that is associated with a clear increase in morbidity and mortality, although systemic manifestations such as glomerulonephritis, cerebral vasculitis or pulmonary vasculitis are very rare. Systemic vasculitis with renal involvement is associated with overt polyarthritis in less than 5% and association with rheumatoid arthritis is exceptional. Determination of anti-neutrophil cytoplasmic autoantibodies (ANCA), used in the appropriate clinical context, has become an important diagnostic tool in small-vessel systemic vasculitides. We present two patients with rheumatoid arthritis who subsequently developed systemic vasculitis. ANCA determination was decisive in the early diagnosis of these patients.     

EFFECTIVENESS OF A MOTOR CONTROL THERAPEUTIC EXERCISE PROGRAM COMBINED WITH MOTOR IMAGERY ON THE SENSORIMOTOR FUNCTION OF THE CERVICAL SPINE: A RANDOMIZED CONTROLLED TRIAL

Background

Motor control therapeutic exercise (MCTE) for the neck is a motor relearning program that emphasizes the coordination and contraction of specific neck flexor, extensor, and shoulder girdle muscles. Because motor imagery (MI) improves sensorimotor function and it improves several motor aspects, such as motor learning, neuromotor control, and acquisition of motor skills, the authors hypothesized that a combination of MCTE and MI would improve the sensorimotor function of the cervical spine more effectively than a MCTE program alone.

Purpose

The purpose of this study was to investigate the influence of MI combined with a MCTE program on sensorimotor function of the craniocervical region in asymptomatic subjects.

Study Design

This study was a single‐blinded randomized controlled trial.

Methods

Forty asymptomatic subjects were assigned to a MCTE group or a MCTE+MI group. Both groups received the same MCTE program for the cervical region (60 minutes), but the MCTE+MI group received an additional intervention based on MI (15 minutes). The primary outcomes assessed were craniocervical neuromotor control (activation pressure value and highest pressure value), cervical kinesthetic sense (joint position error [JPE]), and the subjective perception of fatigue after effort.

Results

Intra‐group significant differences were obtained between pre‐ and post interventions for all evaluated variables (p<0.01) in the MCTE+MI and MCTE groups, except for craniocervical neuromotor control and the subjective perception of fatigue after effort in the MCTE group. In the MCTE+MI group a large effect size was found for craniocervical neuromotor control (d between ‐0.94 and ‐1.41), cervical kinesthetic sense (d between 0.97 and 2.14), neck flexor muscle endurance test (d = ‐1.50), and subjective perception of fatigue after effort (d = 0.79). There were significant inter‐group differences for the highest pressure value, joint position error (JPE) extension, JPE left rotation, and subjective perception of fatigue after effort.

Conclusion

The combined MI and MCTE intervention produced statistically significant changes in sensorimotor function variables of the craniocervical region (highest pressure value, JPE extension and JPE left rotation) and the perception of subjective fatigue compared to MCTE alone. Both groups showed statistically significant changes in all variables measured, except for craniocervical neuromotor control and the subjective perception of fatigue after effort in the MCTE group

Clinical and microbiological characteristics of unusual manifestations of invasive pneumococcal disease

Introduction

Invasive pneumococcal disease (IPD) typically presents as bacterial pneumonia, meningitis or primary bacteraemia. However, Streptococcus pneumoniae can produce infection at any level of the body (endocarditis, arthritis, spontaneous bacterial peritonitis, etc.), which is also known as unusual IPD (uIPD). There are very limited data available about the clinical and microbiological profile of these uncommon manifestations of pneumococcal disease. Our aim was to analyse clinical forms, microbiological profile, epidemiology and prognosis of a cohort of patients with unusual invasive pneumococcal disease (uIPD).
