Abstract: Background To be clinically useful, an instrument assessing health-related quality of life (HRQOL) should be easy to understand and quick to answer. Few instruments have been designed to be short, simple, and easily understandable by patients from all educational levels. The aim of the present study was to evaluate the psychometric properties of a brief general instrument developed to assess HRQOL. Methods Results from a preliminary study regarding the initial development of the Barretos Short Instrument for Assessment of Quality of Life (BSIqol) with 80 cancer patients are presented. Out of all the patients, 59 completed the BSIqol on two occasions in order to evaluate the reproducibility test-retest. Validity analyses were done comparing scores from BSIqol with EORTC QLQ-C30 and Edmonton Symptom Assessment System (ESAS). In addition, BSIqol scores were analyzed in function of ECOG-PS, work activity, and financial income. Results BSIqol demonstrated good internal consistency (Cronbach's α = 0.79) and adequate test-retest reliability, with intraclass coefficient correlation (ICC) varying from 0.736 to 0.946. There were adequate correlations between scores of BSIqol, EORTC QLQ-C30 and ESAS. The BSIqol was capable of discriminating between clinical subgroups, with different ECOG-PS and work activity. Patients completed the BSIqol in a median time <2 min. Only one patient reported some difficulty to answer the instrument. Conclusions BSIqol seems to be a straightforward and useful instrument for rapidly assessing HRQOL from cancer patients. Further studies are necessary to evaluate BSIqol in different populations and also to assess its responsiveness and define its minimal clinically important differences.
High Emotional Arousal Enables Subliminal Detection of Concealed Information  [PDF]
Akemi Osugi, Hideki Ohira
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.810098
Abstract: The Concealed Information Test (CIT) is an information-detecting technique for criminal investigations. Although it has been shown that emotional arousal plays a specific role in the CIT, the mechanisms by which emotional arousal affects the CIT are unclear. The main purpose of this study was to elucidate the processing pathway for stimuli encoded with emotional arousal in a mock crime before the CIT. In this study, participants viewed emotionally arousing pictures before the mock crime. Participants were assigned randomly to either a high or low emotional arousal group, viewing pictures expected to arouse emotion at a high or low level, respectively. Subsequently, all participants enacted the same mock crime, in which they were instructed to stab a pillow with a sharp-edged tool (e.g., kitchen knife or ice pick) as if to harass a woman lying on a bed. After the antecedent emotional experience, a P300-based CIT was conducted using subliminal and supraliminal presentation methods. The results revealed a significantly greater CIT effect on the P300 event-related potential (ERP) component in the High Arousal group compared with the Low Arousal group, under both subliminal and supraliminal conditions. The detection of concealed information was successful only in the High Arousal group under subliminal conditions, whereas detection was successful regardless of the emotional arousal group under supraliminal conditions. These results provide strong evidence that emotional arousal can increase P300 amplitude during responses to concealed information in the CIT. This suggests that concealed information may be automatically processed via the bottom-up route in the CIT, but only when it is encoded with high emotional arousal.

Abstract: Introduction: The cross infection control in dental office has received great attention from professionals and one of the critical points is the bacteriological control of water used in dental unit. Objective: To perform a microbiological evaluation of the water used in dental units, the identification of Gram-negative non-fermentative rods (GNNR) and their ability to adhere to polystyrene, and the antimicrobial activity of disinfectants on the identified strains. Material and methods: The heterotrophic bacteria count and GNNR identification were performed on water samples collected from 25 dental units (air/water syringe and reservoir). The GNNR were assessed on their capability to adhere to polystyrene and on their antimicrobial activity to the following disinfectants: sodium hypochlorite (0.06%, 0.12%, 0.25%, and 0.5%) and chlorhexidine (0.03%, 0.06%, and 0.12%). Results: 88% of the air/water syringe collected samples and 68% of the reservoir collected samples were out of the potability standards. The quantity of isolated bacteria from the reservoir was lower than from the air/water syringe in 88% of the dental units. Methylobacterium spp. was found in highest percentage (19.7%) during GNNR genus isolation. There was a weak adherence to polystyrene in 85.04% of the samples. Sodium hypochlorite at 0.25%, inactivated 100% of the GNNRs in 10 minutes, while the highest tested concentration of chlorhexidine (0.12%), inactivated 98.5% of the GNNRs. Conclusion: These results provide information on the contamination problem of dental unit waterlines (DUWL) and indicate a need for treatment of the water used in dental units. The disinfection of DUWL can be performed with sodium hypochlorite at 0.25% (half the concentration recommended in the literature). However, further studies are necessary regarding DUWL frequency disinfection.
Transmedullary Decompression for Humeral Diaphysis Solitary Bone Cysts  [PDF]

Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.32015

Solitary bone cysts are benign, fluid-filled cavities that most often occur in childhood. Several minimally invasive decompression methods have been proposed; however, performing a surgical procedure through the thinned overlying cortex raises the risk of pathological fracture and neurovascular damage, especially in lesions located in the bone diaphysis. We describe a new technique that circumvents these problems: tunneling through the normal cortex and medullary space with a flexible reamer, placing a retrograde medullary nail for cyst decompression.
