Background: This research aimed to analyze the effect of experience and professional role on psychophysiological stress response in underwater evacuation training. Methods: We analyzed 36 participants (39.06±9.01 years), divided into two different groups; 17 crew members (38.6±7.2 years) and 19 medical members (39.5±10.5 years). modifications in the rating of perceived exertion, subjective stress perception, heart rate, blood oxygen saturation, cortical arousal, heart rate variability, spirometry, isometric hand strength, and short-term memory before and after underwater evacuation training were analyzed. Results: The maneuver produced a significant increase in SSP, RPE, IHS, FVC, and SatO2 at different moments of the intervention, being higher in crew members. Conclusions: We found that the underwater evacuation training produced an anticipatory anxiety response, and an increase in autonomous sympathetic nervous system modulation not affecting strength capacities, cortical arousal, and memory independently of the aircraft role (medical or crew).
Systemic lupus erythematosus is a multi-organ autoimmune disease of unknown etiology characterized by widespread inflammation and significant morbidity and mortality. Organ affection includes joint and cutaneous involvement, pulmonary, neurological, and cardiac problems, renal and hematological involvement as well as ocular comorbidities, both posterior but mostly anterior ocular involvement. Therefore, we aimed to evaluate dry eye involvement in lupus patients. A cross-sectional study was performed with the aid of a web-based, anonymous questionnaire that was distributed to both patients diagnosed with lupus erythematosus and to a control group. A total number of 123 patients diagnosed with lupus and 200 responders in the control group completed the questionnaire. Dry eye disease has already been diagnosed in 25 lupus patients (28.9%) compared to 44 (21.9%) individuals in the control group. Dry eye-related symptomatology was reported in 43 (34.60%) patients compared to 57 (28.35%) healthy responders. Upon statistical analysis, more symptoms were reported in the lupus group (p=0.01), in responders diagnosed with dry eye syndrome (p<0.01), and in responders using lubrication (p<0.01) but no association was obtained between the incidence of dry eye symptoms and the presence of the disease. The number of episodes of lupus reactivation since diagnosis was correlated with dry eye syndrome (p=0.15) and the use of lubricating tear drops (p<0.01). Dry eye symptoms and disease are more frequent in lupus patients and further research should be performed to understand the connection between these two disease entities.
Couvelaire syndrome is a rare complication of pregnancy involving the placenta and the uterine wall. It is caused by placental abruption, preeclampsia, or other disorders that compromise the blood supply to the placenta. Diagnosis is typically made through history, clinical evaluation, and ultrasound. This study aims to report a grave case of Couvelaire syndrome complemented by presenting a review of the relevant literature, to aid the meaning of a clinical path, as well as early and adequate diagnosis and treatment of Couvelaire syndrome, to prevent feto-maternal consequences. The treatment of Couvelaire syndrome depends on the severity of the condition and the well-being of both the mother and the fetus. If the condition is severe and poses a risk to the mother or fetus, immediate delivery may be recommended, mainly with urgent Cesarean section in general endotracheal anesthesia. If there is significant blood loss leading to a decrease in hemoglobin levels, blood transfusions may be necessary to restore normal blood volume and oxygen-carrying capacity. Part of the general treatment plan should also be the management of the underlying cause of placental abruption, for example, in cases of preeclampsia, medications are prescribed to control blood pressure and prevent seizures.
This paper focuses on the role of diffusion-weighted MRI of ovarian tumors as a potential biomarker to detect and characterize malignancy, and to improve the accuracy of preoperative diagnosis and postoperative follow-up to optimize therapeutic management. This is an original retrospective study of 76 patients with ovarian masses who underwent surgery between May 2014 and March 2016 at the "Dr Carol Davila" Central Military University Gynaecology Department. Patients underwent preoperative, 6-month, and 12-month postoperative evaluation of ovarian tumors using diffusion-weighted MRI. Due to the accuracy of this method using specific sequences in tissue characterization, magnetic resonance imaging can be used in the diagnostic work-up of complex adnexal masses.
