Australian uranium deal could make Indian nuclear power safer

[Extract] Australia's prime minister Tony Abbott is set to sign a deal with India that will allow the export of uranium to the country. There are concerns that some of the uranium will be used to produce nuclear weapons in India. It's not likely, though the possibility remains. Critics have also pointed to poor regulation and the lack of transparency in India's nuclear industry. But Australia can play a bigger role in improving India's nuclear industry than just exporting uranium. It can also provide expertise in risk governance and communication

Effects of remote limb ischemic conditioning on muscle strength in healthy young adults: A randomized controlled trial

Remote limb ischemic conditioning (RLIC) is a clinically feasible method in which brief, sub-lethal bouts of ischemia protects remote organs or tissues from subsequent ischemic injury. A single session of RLIC can improve exercise performance and increase muscle activation. The purpose of this study, therefore, was to assess the effects of a brief, two-week protocol of repeated RLIC combined with strength training on strength gain and neural adaptation in healthy young adults. Participants age 18-40 years were randomized to receive either RLIC plus strength training (n = 15) or sham conditioning plus strength training (n = 15). Participants received RLIC or sham conditioning over 8 visits using a blood pressure cuff on the dominant arm with 5 cycles of 5 minutes each alternating inflation and deflation. Visits 3-8 paired conditioning with wrist extensors strength training on the non-dominant (non-conditioned) arm using standard guidelines. Changes in one repetition maximum (1 RM) and electromyography (EMG) amplitude were compared between groups. Both groups were trained at a similar workload. While both groups gained strength over time (P = 0.001), the RLIC group had greater strength gains (9.38 ± 1.01 lbs) than the sham group (6.3 ± 1.08 lbs, P = 0.035). There was not a significant group x time interaction in EMG amplitude (P = 0.231). The RLIC group had larger percent changes in 1 RM (43.8% vs. 26.1%, P = 0.003) and EMG amplitudes (31.0% vs. 8.6%, P = 0.023) compared to sham conditioning. RLIC holds promise for enhancing muscle strength in healthy young and older adults, as well as clinical populations that could benefit from strength training

Patient experiences of adjusting to life in the first two years after bariatric surgery: a qualitative study

Background: There is a limited amount of research into the experiences of those who have undergone bariatric surgery, and how this impacts on their everyday lives and social interactions. Methods Semi-structured interviews were carried out with 18 participants (11 female, 7 male) who had undergone permanent bariatric surgical procedures 5-24 months prior to interview at a large NHS hospital in North East England. Constructivist grounded theory was used, with a constant comparative analytic framework. Results Participants conceptualised social encounters after bariatric surgery as being underpinned by risk. Their attitudes towards social situations guided their actions in the context of social interaction. Three profiles of attitudes towards risk were constructed: Risk Accepters, Risk Contenders and Risk Challengers. These profiles were based on participant-reported narratives of their experiences in the first two years post-surgically Conclusions The social complexities occurring as a consequence of bariatric surgery require adjustments to patients’ lives. Participants reported that the social aspects of bariatric surgery do not appear to be widely understood by those who have had bariatric surgery. The three risk attitude profiles that emerged from our data offer an understanding of ways in which patients adjust to life and can be used reflexively by healthcare professionals in the support of patients both pre- and post-operatively

Genetic variants in ARID5B and CEBPE are childhood ALL susceptibility loci in Hispanics.

Recent genome-wide studies conducted in European Whites have identified novel susceptibility genes for childhood acute lymphoblastic leukemia (ALL). We sought to examine whether these loci are susceptibility genes among Hispanics, whose reported incidence of childhood ALL is the highest of all ethnic groups in California, and whether their effects differ between Hispanics and non-Hispanic Whites (NHWs). We genotyped 13 variants in these genes among 706 Hispanic (300 cases, 406 controls) and 594 NHW (225 cases, 369 controls) participants in a matched population-based case-control study in California. We found significant associations for the five studied ARID5B variants in both Hispanics (p values of 1.0 × 10(-9) to 0.004) and NHWs (p values of 2.2 × 10(-6) to 0.018). Risk estimates were in the same direction in both groups (ORs of 1.53-1.99 and 1.37-1.84, respectively) and strengthened when restricted to B-cell precursor high-hyperdiploid ALL (>50 chromosomes; ORs of 2.21-3.22 and 1.67-2.71, respectively). Similar results were observed for the single CEBPE variant. Hispanics and NHWs exhibited different susceptibility loci at CDKN2A. Although IKZF1 loci showed significant susceptibility effects among NHWs (p < 1 × 10(-5)), their effects among Hispanics were in the same direction but nonsignificant, despite similar minor allele frequencies. Future studies should examine whether the observed effects vary by environmental, immunological, or lifestyle factors

Assessing the safety and efficacy of switching to brinzolamide/timolol fixed combination as a replacement therapy in patients with uncontrolled intraocular pressure in Taiwan

AbstractPurposeThe objective of this study is to assess the safety and efficacy of switching to brinzolamide 1% and timolol 0.5% fixed combination (BTFC) from prior pharmacotherapy in patients with open-angle glaucoma (OAG) or ocular hypertension (OH) in Taiwan.MethodsThis was a multicenter, open-labeled, interventional prospective study. The 8-week study involved patients with OAG or OH with uncontrolled intraocular pressure (IOP) and consisted of three study visits to the clinical site. Patients were instructed to discontinue their prior medications at the first visit, prior to starting the study medication. Enrolled patients were dosed with BTFC twice daily in both eyes for 8 weeks. IOP measurements and safety evaluations were conducted at both Week 4 and Week 8.ResultsA total of 74 patients were enrolled. The overall mean IOP reductions from baseline after Week 8 of BTFC was 3.45 mmHg (15.42%); when subgrouped by prior medication class (β-blockers vs. non-β-blockers), the reduction in mean IOP after transitioning to BTFC at Week 8 was as follows: subgroup β-blockers were 3.23 mmHg (14.9 %) and non-β-blockers were 3.58 mmHg (15.25%). All mean IOP changes from baseline were statistically significant (p < 0.001). Of the 69 patients (per protocol population) who were switched to BTFC regardless of prior therapy, 37 (53.6%) patients at Week 4 and 38 (55.1%) patients at Week 8 had IOP ≤ 18 mmHg. No treatment-related serious adverse events were reported in this study.ConclusionThe results of this study demonstrated the potential benefit of using BTFC as a replacement therapy in order to ensure adequate IOP control. BTFC administered twice daily was safe and effective in patients with uncontrolled IOP in Taiwan

Gait and Function in Class III Obesity

Walking, more specifically gait, is an essential component of daily living. Walking is a very different activity for individuals with a Body Mass Index (BMI) of 40 or more (Class III obesity) compared with those who are overweight or obese with a BMI between 26–35. Yet all obesity weight classes receive the same physical activity guidelines and recommendations. This observational study examined the components of function and disability in a group with Class III obesity and a group that is overweight or has Class I obesity. Significant differences were found between the groups in the areas of gait, body size, health condition, and activity capacity and participation. The Timed Up and Go test, gait velocity, hip circumference, and stance width appear to be most predictive of activity capacity as observed during gait assessment. The findings indicate that Class III-related gait is pathologic and not a normal adaptation
