Abstract
Tool use can be inherited, or acquired as an individual innovation or by social transmission. Having previously reported individual innovative tool use and manufacture by a Goffin cockatoo, we used the innovator (Figaro, a male) as a demonstrator to investigate social transmission. Twelve Goffins saw either demonstrations by Figaro, or 'ghost' controls where tools and/or food were manipulated using magnets. Subjects observing demonstrations showed greater tool-related performance than ghost controls, with all three males in this group (but not the three females) acquiring tool-using competence. Two of these three males further acquired tool-manufacturing competence. As the actions of successful observers differed from those of the demonstrator, result emulation rather than high-fidelity imitation is the most plausible transmission mechanism.

Abstract
We present a simple and versatile polarimeter for x rays in the energy range of 10-30 keV. It uses Compton scattering in low-Z materials such as beryllium or boron carbide. The azimuthal distribution of the scattered x rays is sampled by an array of 12 silicon PIN diodes operated at room temperature. We evaluated the polarimetry performance using Monte-Carlo simulations and show experimental results.

Abstract
We experimentally study the effects of the anisotropic Rydberg interaction on D-state Rydberg polaritons slowly propagating through a cold atomic sample. We observe the interaction-induced dephasing of Rydberg polaritons at very low photon input rates into the medium. We develop a model combining the propagation of the two-photon wave function through our system with nonperturbative calculations of the anisotropic Rydberg interaction to show that the observed effect can be attributed to pairwise interaction of individual Rydberg polaritons at distances larger than the Rydberg blockade.

Abstract
PURPOSE To review data on health-related quality of life (HRQoL) in individuals with childhood trauma, including psychological maltreatment, physical maltreatment, sexual abuse, and neglect. METHODS The literature search was conducted with pre-defined keywords using the following electronic bibliographic databases: EMBASE, PubMed, MEDLINE, CINAHL, PsyINFO, PSYNDEX, and Cochrane Database of Systematic Reviews. Further databases were searched for relevant dissertations. Study selection and data extraction were completed by two independent reviewers. RESULTS The literature search yielded 1568 entries. Nineteen articles met all inclusion criteria and were retained for further analysis. Findings quite consistently showed significant negative associations between child maltreatment and both self- and proxy-rated HRQoL. Effect sizes range from small to large. Number of types of maltreatment and HRQoL were found to be negatively related. CONCLUSION Data on HRQoL for maltreated children are still rare. Studies often investigate adult survivors of child maltreatment. Considering HRQoL in children and adolescents who suffered maltreatment would allow the planning of effective interventions and the evaluation of treatments to improve HRQoL of these children.

Abstract
Background: The clinical value of inflammatory biomarkers is still questionable. Aim of the Work: The aim of this study is to compare the clinical informative value of procalcitonin (PCT) and C-reactive protein (CRP) plasma concentration in the early detection of sepsis, as well as relating these biomarkers to other scoring systems. Patients and Methods: A total of 138 patients were enrolled in our study. All were subjected to PCT, CRP, and sequential organ failure assessment (SOFA) scores daily for 7 days (starting from admission day). Blood samples were collected before starting antibiotics, with 28 days follow-up and patients were assigned to three groups: Group I: SOFA 2-7, Group II: SOFA 8-10, and Group III: SOFA ≥11. Results: Underlying clinical diagnosis revealed pneumonia in 72 patients, urinary tract infections in eight, bloodstream infection in four, and other infections in 23, while infection could not be traced in 25 patients. The mean PCT was 3 ng/ml (95% confidence interval [CI]: 1-4), 12 ng/ml (95% CI: 9.1-14), and 19 ng/ml (95% CI: 16.3-22.3) in Groups I, II, and III, respectively, with a statistically significant difference in the mean PCT level among the three groups (P < 0.0001). On the other hand, CRP mean level did not significantly differentiate between the groups (147.1 mg/L in Group II, which was even higher than the level of Group III, 138.4 mg/L). Conclusion: PCT seems to do better than CRP in predicting the SOFA groups, giving its patronage display over a wide spectrum of insults.

Abstract
Two commercial kretek cigarettes typical for the Indonesian market and a reference kretek cigarette were compared to the American-blended reference cigarette 2R4F by smoke chemistry characterization and in vitro cytotoxicity and mutagenicity assessments. Despite the widely diverse designs and deliveries of the selected kretek cigarettes, their smoke composition and in vitro toxicity data present a consistent pattern when data were normalized to total particulate matter (TPM) deliveries. This confirms the applicability of the studies' conclusions to a wide range of kretek cigarette products. After normalization to TPM delivery, nicotine smoke yields of kretek cigarettes were 29-46% lower than that of the 2R4F. The yields of other nitrogenous compounds were also much lower, less than would be expected from the mere substitution of one third of the tobacco filler by clove material. Yields of light molecular weight pyrolytic compounds, notably aldehydes and hydrocarbons, were reduced, while yields of polycyclic aromatic hydrocarbons were unchanged and phenol yield was increased. The normalized in vitro toxicity was lowered accordingly, reflecting the yield reductions in gas-phase cytotoxic compounds and some particulate-phase mutagenic compounds. These results do not support a higher toxicity of the smoke of kretek cigarettes compared to American-blended cigarettes.

Abstract
High brain and acute leukemia, cytoplasmic (BAALC) expression defines an important risk factor in cytogenetically normal acute myeloid leukemia (CN-AML). The prognostic value of BAALC expression in relation to other molecular prognosticators was analyzed in 326 CN-AML patients (<65 years). At diagnosis, high BAALC expression was associated with prognostically adverse mutations: FLT3 internal tandem duplication (FLT3-ITD) with an FLT3-ITD/FLT3 wild-type (wt) ratio of ⩾0.5 (P=0.001), partial tandem duplications within the MLL gene (MLL-PTD) (P=0.002), RUNX1 mutations (mut) (P<0.001) and WT1mut (P=0.001), while it was negatively associated with NPM1mut (P<0.001). However, high BAALC expression was also associated with prognostically favorable biallelic CEBPA (P=0.001). Survival analysis revealed an independent adverse prognostic impact of high BAALC expression on overall survival (OS) and event-free survival (EFS), and also on OS when eliminating the effect of allogeneic stem cell transplantation (SCT) (OSTXcens). Furthermore, we analyzed BAALC expression in 416 diagnostic and follow-up samples of 66 patients. During follow-up, BAALC expression correlated with mutational load or expression levels, respectively, of other minimal residual disease markers: FLT3-ITD (r=0.650, P<0.001), MLL-PTD (r=0.728, P<0.001), NPM1mut (r=0.599, P<0.001) and RUNX1mut (r=0.889, P<0.001). Moreover, a reduction in BAALC expression after the second cycle of induction chemotherapy was associated with improved EFS. Thus, our data underline the utility of BAALC expression as a marker for prognostic risk stratification and detection of residual disease in CN-AML.

Abstract
OBJECTIVE To determine the efficacy and safety of linagliptin in initial combination with metformin in patients with type 2 diabetes. METHODS This 1-year randomised, double-blind study was an extension of a 6-month randomised controlled trial, in which adults with type 2 diabetes received one of six treatment regimens (linagliptin 2.5 mg plus metformin 500 mg bid, linagliptin 2.5 mg plus metformin mg 1000 bid, metformin 1000 mg bid, metformin 500 mg bid, linagliptin 5 mg qd or placebo). In the extension, patients in the first three treatment groups continued their regimen (non-switched group, n = 333) while the metformin 500 mg bid, linagliptin 5 mg qd and placebo groups were re-randomised to one of the three continuing regimens (switched group, n = 233). RESULTS All three non-switched groups maintained reductions in glycosylated haemoglobin (HbA1c; mean ± standard deviation reductions across the 1.5-year period: linagliptin 2.5 plus metformin 1000 bid, -1.63 ± 1.05%; linagliptin 2.5 plus metformin 500 bid, -1.32 ± 1.06%; metformin 1000 bid, -1.25 ± 0.91%) while the switched groups showed additional HbA1c reductions. During the extension, there were no clinically meaningful changes in body weight in any group. Adverse event rates were similar between groups, with most events being mild or moderate, and the incidence of investigator-defined hypoglycaemia was low, with no severe events. DISCUSSION Initial combination of linagliptin and metformin was well tolerated over the 1-year extension period, with low risk of hypoglycaemia, and improved glycaemic control vs. metformin alone. CONCLUSION The initial combination of linagliptin and metformin appears to provide a useful treatment option in patients whose blood glucose levels are increased to an extent that metformin monotherapy may not achieve treatment targets.
