Abstract
Abstract
Purpose: Early discontinuation or non-adherence of AI therapy occurs in 25-50 % of patients due to treatment associated toxicities, including musculoskeletal symptoms such as arthralgias and myalgias. The goal of this pilot study is to evaluate the effect of a directed physical therapy regimen including joint mobility and stretching exercises on musculoskeletal symptoms resulting from AI therapy, in comparison to normal physical activity alone.
Patients and methods: Eligibility criteria included post-menopausal women with histological evidence of hormone receptor positive breast cancer who were currently receiving adjuvant AI therapy and experiencing significant joint discomfort/stiffness when attempting activities of daily living which began or significantly increased after initiation of AI therapy. Patients were excluded if they had preexisting rheumatoid arthritis or fibromyalgia, systemic metastasis or ECOG performance status of greater than 2. Patients were randomly assigned to an 8 week directed exercise program under the supervision of a physical therapist (Group A, n=15) or were told to participate in moderate physical activity (walking) (Group B, n=12). Before beginning the study and at the end of the 8 week intervention, patients in both groups underwent a physical therapy evaluation including performance based measures such as functional lower extremity strength and grip strength and a Patient Specific Functional Scale (PSFS) to assess functional ability to complete specific activities. Additionally, all patients answered a series of questionnaires including a pain disability index (PDI), pain scale (PS) and the PHQ4 depression scale. Effects of the directed exercise regimen were evaluated using non-parametric analysis to determine differences between the two groups.
Results: Significant improvement was observed in both left and right grip strength and right pinch in the intervention group (Group A) as compared to the control group (Group B). Additionally, significant improvement in lower body measures including 2-minute step tests and chair raises were observed in patients who underwent the directed exercise program compared to the control group. No significant differences were observed in PS, PDI or PHQ4 between the groups. However, Group A showed a slight improvement on the PS and PDI.
Conclusions: Directed exercise regimens involving joint mobility and stretching exercises may have benefits over moderate physical activity alone for joint pain and arthralgia associated with AI therapy.

Abstract
BACKGROUND Meticillin-resistant Staphylococcus aureus (MRSA) bacteraemia cases have declined since 2003, and have mostly been due to two epidemic (E) strains, E15 (multi-locus sequence type clonal complex CC22) and E16 (CC30). By contrast, the incidence of meticillin-susceptible S. aureus (MSSA) bacteraemia has remained largely unchanged and our understanding of these isolates has remained poor. AIM To investigate the distribution and nucleotide sequence of heterogeneous regions between successful lineages using the 2009 British Society for Antimicrobial Chemotherapy (BSAC) Bacteraemia Resistance Surveillance Programme collection of S. aureus. METHODS S. aureus isolates (N = 202) comprised of 103 MRSA and 99 MSSA isolates were analysed using fluorescent amplified fragment length polymorphism (FAFLP) to detect nucleotide variations due to lineage-specific sequence motifs as well as differences in the distribution of mobile genetic elements between lineages. FINDINGS E15 and E16 MRSA strains comprised 79% and 6% of the collection in 2009 respectively. Six lineages, including CC22 and CC30, were associated with MRSA bacteraemia in the UK and Ireland. MSSA isolates were more diverse with 19 different lineages detected. FAFLP revealed lineage-specific sequence variations in loci encoding factors such as proteases or factors involved in haem biosynthesis, both of which may affect the success of major S. aureus lineages. Proteins encoded on certain mobile genetic elements or involved in cobalamin biosynthesis were found to be exclusive to CC8, CC22, or CC30. CONCLUSION Overall, the genetic diversity among regions of the core genome and mobile genetic elements may alter antimicrobial resistance and the production of virulence or fitness factors that may be linked to strain success.

Abstract
The scalability of a quantum network based on semiconductor quantum dots lies in the possibility of having an electrical control of the quantum dot state as well as controlling its spontaneous emission. The technological challenge is then to define electrical contacts on photonic microstructures optimally coupled to a single quantum emitter. Here we present a novel photonic structure and a technology allowing the deterministic implementation of electrical control for a quantum dot in a microcavity. The device consists of a micropillar connected to a planar cavity through one-dimensional wires; confined optical modes are evidenced with quality factors as high as 33,000. We develop an advanced in-situ lithography technique and demonstrate the deterministic spatial and spectral coupling of a single quantum dot to the connected pillar cavity. Combining this cavity design and technology with a diode structure, we demonstrate a deterministic and electrically tunable single-photon source with an extraction efficiency of around 53±9%. Bright and tunable single-photon sources are essential for future quantum technologies. Here, the authors deterministically couple a quantum dot to a pillar structure that enables application of electric fields to provide a tunable single-photon source with a demonstrated extraction efficiency of 53%.

Abstract
The usual treatment of venous ulcers may be associated with statins intake. Antibiotics have only marginal utility in acute bronchitis. The prescription of paracetamol seems to have no benefit in the treatment of acute lower back pain. The absence of antithrombotic prophylaxis for distal fractures of the lower limbs seems to be safe for patients' health. The treatment of atraumatic lesions of the rotator cuff in patients >55 years should remain conservative. Arthroscopic surgery of non-traumatic tear of the medial meniscus seems to have no benefit. The family environment seems to be a protective factor to the mental health of adolescents. Screening for colorectal cancer in patients >75 years would save lives.

Abstract
OBJECTIVE Adequate nutrition is paramount for premature infants. Longitudinal information is scant on the effects of early nutrition and later growth. The purpose of this study was to determine the influence of early energy and protein provision in premature infants on adolescent body composition and blood pressure. METHODS In 2007-2008 we obtained data from 36 male (12.3±1.7 years) and 25 female (11.5±1.8 years) adolescents born preterm at <34 weeks gestation (range 23-34 weeks) between October 1st 1989 and December 31st 1995 (birth weight <1850 g). The adolescents were divided into groups depending on infant intake mode (enteral vs parenteral), energy provision (<70 kcal/kg/d and ≥70 kcal/kg/d) and protein provision (>2.5 g/kg/d for ≥5 days and >2.5 g/kg/d for <5 days) during the first 14 days of life. RESULTS After controlling for birth weight and biological maturity, adolescents who received ≥70 kcal/kg/d during infancy were significantly taller (163±11 cm vs. 156±11 cm) and heavier (58±16 kg vs. 49±16 kg) than adolescents who received <70 kcal/kg/d. There were no significant differences in systolic and diastolic BP and total percent body fat between the two groups. CONCLUSIONS Our data suggests that higher infant energy provision appears to be related to adolescent size, it does not appear to contribute to adverse risk factors such as higher systolic BP or increased body fat.

Abstract
BACKGROUND As endometriosis is known to be very painful in humans, therapeutic studies should consider pain-related aspects in experimental animals too. In a previous study, we found that common marmosets suffering from endometriosis show remarkable deviations in social behavior and cognitive tasks. METHODS Female marmosets with endometriosis undergoing medical treatment were tested vs. two control groups (healthy and endometriosis monkeys without treatment) concerning behavioral aspects, cognitive skills, and mobility. RESULTS The treated monkeys performed significant more social and self-grooming, comfort behavior and were more active than the untreated endometriosis monkeys. The treated marmosets even returned to equal levels as their healthy conspecifics. Cognitive and mobility tests revealed no significant differences. CONCLUSIONS A beneficial effect of the applied endometriosis medication on behavioral impairments could be obtained. Including such measurements in therapeutic research contributes to aspects of animal welfare and pain-relieving potential of the tested compound.

Abstract
Giant optical nonlinearity is observed under both continuous wave and pulsed excitation in a deterministically coupled quantum dot-micropillar system, in a pronounced strong-coupling regime. Using absolute reflectivity measurements we determine the critical intracavity photon number as well as the input and output coupling efficiencies of the device. Thanks to a near-unity input-coupling efficiency, we demonstrate a record nonlinearity threshold of only 8 incident photons per pulse. The output-coupling efficiency is found to strongly influence this nonlinearity threshold. We show how the fundamental limit of single-photon nonlinearity can be attained in realistic devices, which would provide an effective interaction between two coincident single-photons.

Abstract
Behcet's disease is a disease of unknown etiology resting in between vasculitis, spondyloarthropathy and autoinflammatory diseases. If his predilection for the population originating from the Silk Road is well known, as are its cutaneous, ocular and vascular manifestations, this case illustrates the non-specificity of those manifestations, the diagnostic difficulties and the importance of routinely assessing for eyes and bowel diseases in this type of patient.
