Can we identify the poorest quality of life? Assessing the importance of quality of life using the WHOQOL-100

In this study, WHOQOL survey data obtained from 4802 sick and well participants in 15 countries were used to investigate the relationship between judgements about different dimensions of quality of life (QOL) (core scores) and the importance attributed to them. As a theoretical framework, we applied the WHOQOL Group's (1995) definition of QOL which indicates that those who report the very poorest QOL will be least likely to have met their own '...goals, expectations, standards and concerns'. Those with the poorest QOL would therefore be expected to show the biggest difference between core and importance scores, and therefore be distinguishable from respondents whose QOL was poor, better or best. The main effects from overall analyses confirmed that those reporting the largest negative differences tended to report the poorest QOL and also attached a high degree of importance to these dimensions. Evidence for a decreasing differential across the four groups (poorest to best) was confirmed for the majority (18) of facets. However facet level analyses comparing groups with different levels of QOL showed that only five facets distinguished those with the poorest QOL from those whose QOL was poor, so the theory is not well supported. Furthermore the contribution of core-importance facet differences reduced the overall prediction of QOL, when compared with a regression of core scores alone. Importance information about specific facets may have limited potential to be used alongside the main instrument to identify areas of the poorest QOL for clinical or social action.     

Safety and efficacy of weight training in recent breast cancer survivors to alter body composition, insulin, and insulin-like growth factor axis proteins.

BACKGROUND: This randomized controlled trial assessed the safety and effects of twice-weekly weight training among recent breast cancer survivors. Outcomes included body size and biomarkers hypothesized to link exercise and breast cancer risk. METHODS: A convenience sample of 85 recent survivors was randomized into immediate and delayed treatment groups. The immediate group trained from months 0 to 12; the delayed treatment group served as a no exercise parallel comparison group from months 0 to 6 and trained from months 7 to 12. Measures at baseline, 6 and 12 months included body weight, height, body fat, lean mass, body fat %, and waist circumference, as well as fasting glucose, insulin, insulin resistance, insulin-like growth factor-I (IGF-I), IGF-II, and IGF-binding protein-1, IGFBP-2, and IGFBP-3. Injury reporting was standardized. RESULTS: The intervention resulted in significant increases in lean mass (0.88 versus 0.02 kg, P < 0.01), as well as significant decreases in body fat % (-1.15% versus 0.23%, P = 0.03) and IGF-II (-6.23 versus 28.28 ng/mL, P = 0.02) comparing immediate with delayed treatment from baseline to 6 months. Within-person changes experienced by delayed treatment group participants during training versus no training were similar. Only one participant experienced a study related injury that prevented continued participation. CONCLUSION: Twice-weekly weight training is a safe exercise program for recent breast cancer survivors that may result in increased muscle mass, as well as decreased body fat % and IGF-II. The implications of these results on cancer recurrence or survival may become more evident with longer exercise intervention trials among breast cancer survivors.     

Remote Echography between a Ground Control Center and the International Space Station Using a Tele-operated Echograph with Motorized Probe

Echography is the most appropriate imaging modality for investigating astronauts. Unfortunately, it requires a great deal of training to perform ultrasound examinations, which can be difficult and time consuming, especially if the astronaut does not have a medical background. We designed a new echography system with motorized probes that allows for the majority of exam functions to be controlled by a ground-based sonographer. Using tele-operation, the sonographer controls the orientation of the transducer (tilt, rotation) and echograph settings (gain, depth, freeze) and triggers ultrasound functions (pulsed wave color Doppler, 3-D capture, radiofrequency data collection, elastography). With this system, astronauts are required to hold the motorized probe only at the locations indicated, with the remainder of the exam being conducted by the ground-based sonographer. During spaceflight, ultrasound imaging of the carotid artery, jugular vein, thyroid, liver, gallbladder, biliary tract and portal vein (2-D, 3-D, color, pulsed wave, radiofrequency) were successfully performed.     

Quality of Life and Long-Term Therapy in Patients with Chronic Myeloid Leukemia

Since the development of imatinib and other tyrosine kinase inhibitors (TKIs), the prognosis for patients with chronic myeloid leukemia (CML) has markedly improved, such that most patients diagnosed with CML can now expect to live with their disease rather than die from it. However, most patients will require long-term treatment, which has deleterious effects on health-related quality of life. We review recent literature on drug-related adverse effects, long-term medication adherence, limitations to fertility and pregnancy, effects on cognitive function, ability to work, financial toxicity, pediatric populations, and treatment discontinuation. While patients with CML are fortunate to have excellent therapies available to control their disease, many are unable to lead normal lives, which challenges the notion that research is no longer needed in CML. Curing CML, i.e., no detectable disease and no need for daily medications, should remain the ultimate goal.     

Risk factors for the development of PTSD and depression among child and adolescent victims following a 7.4 magnitude earthquake

Objective. PTSD and major depression occur frequently following traumatic exposure, both as separate disorders and concurrently. Although much of Turkey is under threat of severe earthquakes, risk factors for developing psychiatric disorders among Turkish children have not yet been studied. The aim of the study was to examine risk factors for PTSD and depression develpoment in children. Method. A total of 160 survivors (102 girls and 58 boys) severely impacted by Turkey's 7.4-magnitude quake participated in a psychiatric interview 6–20 weeks after the disaster. The mean age was 14.43. Logistic regression was used to test effects of pre-disaster, disaster-related and post-disaster factors on diagnoses, yielding odds ratios (OR). Results. CAPS indicated that 96 (60%) had PTSD, and psychiatric interview found 49 (31%) with depression. Children diagnosed with PTSD were more likely to have witnessed death (OR=2.47) and experienced an extreme parental reaction (OR=3.45). Children with depression were more likely to be male (OR=4.48), have a higher trait anxiety score (OR=1.12 for every additional point), sustain injury (OR=4.29), and have lost a family member in the quake (OR=10.96). Focusing on the 96 children with PTSD, those with comorbid depression were more likely male, have a higher trait anxiety score, and have lost of family member. Conclusions. Mental health professionals should offer support to children witnessing death or losing a family member in a disaster. The ability of the family to remain calm and reassuring also may be a key factor in preventing PTSD.
