in subacromial impingement are best predicted by the width of the subdeltoid bursa measured in the coronal MRI plane as an indicator of bursitis as well as the presence of a "halo-sign" around the biceps tendon indicating glenohumeral joint effusion. Presence of a subacromial spur could lead to subacromial and subdeltoid bursitis, which impairs shoulder function. Shoulder function seems not to be compromised by the presence of a subacromial spur in absence of bursitis. This study was registered at the German Clinical Trials Register on 08 February 2013 (ID DRKS00011548).
Short femoral hip stems with a metaphyseal anchoring concept have been designed to treat younger patients with good bone quality. The aim of this study was to reconstruct the centre of rotation and soft tissue balancing and preserve bone in the long-term perspective.

Eighteen human femurs were randomised into three groups (1) metaphyseal anchoring short stem, (2) shortened straight stem, (3) straight stem). Prior to the implantation of the hip stems, a computed tomography (CT) of the bones was performed and the femoral ante-torsion and ante-tilt was measured and compared to the results of the post-implantation CT. This could be calculated based on the 3D coordinates taken from the pre- and post-op CT scans, which were transformed into the same coordinate systems.

The mean preoperative caput-collum-diaphyseal (CCD) angle for the three groups was 126.87° ± 3.50° (Group 3 129.64° ± 3.53°, Group 1 123.76° ± 5.56°, Group 2 127.53° ± 1.42°) and was consistent with published reports. The postoperative CCD angles with 126.85° ± 3.43° were within a very good reconstruction range for all three groups. The anterior offset comparison among these three groups showed significant difference in reconstruction. The smallest difference between the anatomical (preoperative) and postoperative condition was seen in Group 1 (1.47° ± 0.60°), followed by Group 2 (3.60° ± 0.23°) and Group 3 (8.00° ± 0.70°) groups. The horizontal offset showed no significant difference among the groups and was within the window of ± 5mm.

In this cadaver study, we found that the metaphyseal anchoring, partially neck-preserving short hip stem best reconstructs the ante-torsion and the ante-tilt of the femoral neck. Therefore, it can be a useful stem in younger or active middle-aged patients.

Ease of generation of 14 C5H5+ isomers by ionic dissociation of halide precursors does not correlate well with carbocation stability. The reaction profiles of concerted isomerization of various C5H5+ cations to six select cations are established along with the respective transition states. The rate coefficients of these processes are estimated by using transition state theory and activation energies computed. The transition states for these six reactions are characterized with regard to position along the isomerization pathway as per Hammond's postulate. ABT-199 Bcl-2 inhibitor The 6 isomerization reactions are combined to yield multi-step conversions of various C5H5+ species to the lowest energy vinylcyclopropenyl cation 1. Finally, three different routes for obtaining the select cations from C5H5Br precursors are profiled and the most favored pathways predicted.Artificial intelligence can be a game changer to address the global challenge of humanity-threatening climate change by fostering sustainable development. Since chemical research and development lay the foundation for innovative products and solutions, this study presents a novel chemical research and development process backed with artificial intelligence and guiding ethical principles to account for both process- and outcome-related sustainability. Particularly in ethically salient contexts, ethical principles have to accompany research and development powered by artificial intelligence to promote social and environmental good and sustainability (beneficence) while preventing any harm (non-maleficence) for all stakeholders (i.e., companies, individuals, society at large) affected.
Tyrosine kinase inhibitors (TKIs) substantially improve survival for patients with chronic myeloid leukemia (CML), but fatigue associated with TKIs can negatively impact patients' quality of life and adherence. This study sought to identify correlates of fatigue (e.g., sociodemographic characteristics, clinical characteristics, health behaviors) among patients with CML taking TKIs who reported moderate to severe fatigue.

Adults with CML experiencing at least moderate fatigue were recruited for a pilot trial of a cognitive behavioral intervention to improve fatigue. Data collected pre-intervention were used to explore concurrent correlates of fatigue in univariate and multivariable models.

Participants (N = 44, 48% female) were M = 55.6years old (SD = 12.6) and had been diagnosed with CML M = 5.2years prior (SD = 5.3). Participants had been taking their current TKI for M = 2.5years (SD = 2.7). Most participants (64%) had previously been treated with ≥ 1 other TKI. More than three-quarters of participants (77%) reported severe fatigue. In univariate models, worse fatigue was associated with higher BMI (r = -0.36, p = 0.018), prior treatment with other TKI(s) (r =  - 0.34, p = 0.024), worse sleep disturbance (r =  - 0.51, p < 0.001), and less physical activity (r = 0.31, p = 0.043). In a multivariable model, significant univariate correlates accounted for 39% of the variance in fatigue. Worse fatigue remained significantly correlated with higher BMI (β =  - 0.33, p = 0.009) and more disturbed sleep (β =  - 0.45, p < 0.001).

Results may inform future research aiming to identify fatigued patients with CML at risk for experiencing more severe fatigue during TKI therapy. Identifying predictors of fatigue severity could aid clinicians in identifying which patients will benefit from referrals to supportive therapy.
