Article Synopsis
  • This study evaluated modified Radiographic Union Scale for Tibia (mRUST) scores over time in patients with distal femur fractures treated with intramedullary nails, to identify factors influencing healing and possible reoperation.
  • Conducted in ten Level I Trauma Centers, the research included 155 fractures from 152 patients, focusing on mRUST scores at 3, 6, and 12 months post-surgery, with the primary goal of finding predictors for union timing.
  • Results showed that a 3-month mRUST score of ≤8 indicated a higher chance of reoperation, and factors such as tobacco use and open fractures correlated with delayed healing times.

Article Synopsis
  • - The study aimed to identify risk factors for unplanned reoperations related to union promotion or deep surgical-site infections (DSSI) in patients with periprosthetic distal femur fractures treated with lateral distal femoral locking plates (LDFLPs).
  • - Conducted across ten level-I trauma centers, the retrospective cohort study focused on patients diagnosed with specific fracture types between January 2012 and December 2019 while excluding those with pathological fractures or less than three months of follow-up.
  • - Results showed an 8.3% reoperation rate for union promotion linked to factors like higher body mass index and more screws in the distal segment, while no significant factors were identified for DSSI-related reoperations.

Article Synopsis
  • - The study aimed to evaluate the clinical and functional outcomes of nail-plate fixation (NPF) for distal femur fractures and to compare these outcomes with those of patients treated with single lateral locking plates.
  • - Conducted at ten trauma centers, the retrospective cohort study found that NPF resulted in significantly lower rates of unplanned reoperations and varus collapse compared to the lateral locking plate treatment group.
  • - The researchers concluded that NPF is a promising option for complex fractures, with larger studies recommended to further identify which patients benefit most from this treatment.

(1) Background: 5p minus Syndrome (S5p-) is a neurodevelopmental disorder caused by a deletion in the short arm of chromosome 5. Among the phenotypic characteristics of S5p-, the most characteristic and representative element is a monochromatic cry with a high-pitched tone reminiscent of a cat's meow. Individuals may also show great phenotypic heterogeneity and great genetic variability.

Chromosome-5p minus syndrome (5p-Sd, OMIM #123450) formerly known as syndrome results from the loss of genetic material at the distal region of the short arm of chromosome 5. It is a neurodevelopmental disorder of genetic cause. So far, about 400 patients have been reported worldwide.

The aim of this paper is to present the methodology and results of a study on the role played by an institution in higher education, the ESIC Business & Marketing School, in teaching different master's degree programmes to examine whether they respond to the demands of potential entrepreneurs who are seeking to acquire the tools and develop the skills necessary to eventually become successful. The main conclusions were that the students with the intention of achieving a higher level of entrepreneurial skills were enroled in the Executive Master of Business Administration (EMBA) programme without omitting other master's degree programmes also chosen by students with entrepreneurial concerns. It was also found that the variable with the highest impact on entrepreneurial motivation was family environment.

Purpose: To compare rotational stability, centration and visual outcomes provided by three trifocal lens models that have the same optical zone design but different material, composition, and/or toricity.

Methods: The study included 78 patients with symmetric bilateral intraocular lens implantation. The lenses under evaluation were trifocal intraocular lenses made of hydrophilic acrylic material: a spherical lens 26% hydrophilic acrylic (POD FineVision), a similar lens but having a toric design (POD Toric FineVision), and a trifocal lens 25% hydrophilic acrylic material (FineVision/MicroF).

Background: The Active Living Logan Square target audience is the community of the southwest corner of Logan Square, an urban Chicago community of 84,466 residents, mostly Latinos. Through the Active Living by Design (ALbD) initiative, the Logan Square Neighborhood Association leveraged its 48 years of existence in the neighborhood to create opportunities and build partnerships.

Intervention: Activities addressed three primary goals: (1) enhance school environments and practices to support physical activity before, during, and after the school day; (2) encourage individuals and families to enjoy outdoor activities in their own communities; and (3) create safe, inviting places for activity that connect to surrounding communities.

Bayesian averaging (BA) over ensembles of decision models allows evaluation of the uncertainty of decisions that is of crucial importance for safety-critical applications such as medical diagnostics. The interpretability of the ensemble can also give useful information for experts responsible for making reliable decisions. For this reason, decision trees (DTs) are attractive decision models for experts.

The interpretation of a Thurstonian model for paired comparisons where the utilities' covariance matrix is unrestricted proved to be difficult due to the comparative nature of the data. We show that under a suitable constraint the utilities' correlation matrix can be estimated, yielding a readily interpretable solution. This set of identification constraints can recover any true utilities' covariance matrix, but it is not unique.

We introduce a multidimensional item response theory (IRT) model for binary data based on a proximity response mechanism. Under the model, a respondent at the mode of the item response function (IRF) endorses the item with probability one. The mode of the IRF is the ideal point, or in the multidimensional case, an ideal hyperplane.
