Background: No reliable statistics exist for injury rates among occasional woodcutters as opposed to professional loggers. Study objectives were to assess woodcutting injuries seen in emergency rooms and identify risk factors.
Methods: Individuals with woodcutting related injuries were identified in 14 emergency and urgent care departments in central and northern Wisconsin. A telephone survey was conducted within 3 weeks of presentation to determine number and types of injuries, causes, and characteristics of the injured.
Results: Three times as many woodcutting-related injuries occurred in non-logger survey participants (54 vs. 17). There was no significant difference in age or type of injury. Loggers were more likely to wear personal protective equipment. Younger individuals attributed their accidents to human errors, whereas older individuals felt their injuries were unavoidable.
Conclusions: Occasional woodcutting activities result in comparable, but more frequent injuries than professional logging activities. Further data are needed to assess impact on public safety.

We introduce an approach for analyzing the responses of dynamical systems to external perturbations that combines score-based generative modeling with the generalized fluctuation-dissipation theorem. The methodology enables accurate estimation of system responses, including those with non-Gaussian statistics. We numerically validate our approach using time-series data from three different stochastic partial differential equations of increasing complexity: an Ornstein-Uhlenbeck process with spatially correlated noise, a modified stochastic Allen-Cahn equation, and the 2D Navier-Stokes equations.

This paper presents an in-depth theoretical analysis of the orientation selectivity properties of simple cells and complex cells, that can be well modelled by the generalized Gaussian derivative model for visual receptive fields, with the purely spatial component of the receptive fields determined by oriented affine Gaussian derivatives for different orders of spatial differentiation. A detailed mathematical analysis is presented for the three different cases of either: (i) purely spatial receptive fields, (ii) space-time separable spatio-temporal receptive fields and (iii) velocity-adapted spatio-temporal receptive fields. Closed-form theoretical expressions for the orientation selectivity curves for idealized models of simple and complex cells are derived for all these main cases, and it is shown that the orientation selectivity of the receptive fields becomes more narrow, as a scale parameter ratio , defined as the ratio between the scale parameters in the directions perpendicular to vs.

Background: Since the COVID-19 pandemic, health care workers (HCWs) faced an enormous physical and mental burden, sometimes altering their quality of life due mainly to persistent challenges stemming from their frontline position.
Aims: Todetermine the prevalence of post-COVID-19 syndrome, and its impact on the Health-Related Quality of Life (HRQoL) among HCWs.
Methods: This is an exhaustive cross-sectional study with analytical scope, conducted among all HCWs of the University Hospital Sahloul of Sousse, Tunisia, who have contracted COVID-19 between September 2020 and 30 March 2021 (N=529 cases).

Introduction: Elbow ailments are common, but conventional treatment modalities have shortcomings, offering only interim pain relief rather than targeting the underlying pathophysiology. The last two decades have seen a marked increase in the use of autologous peripheral blood-derived orthobiologics (APBOs), such as platelet-rich plasma (PRP), to manage elbow disorders. Platelet-rich plasma (PRP) is the most widely used APBO, but its efficacy remains debatable.

The third most prevalent type of cancer in the world, colorectal cancer, poses a significant treatment challenge due to the nonspecific distribution, low efficacy, and high systemic toxicity associated with chemotherapy. To overcome these limitations, a targeted drug delivery system with a high cytotoxicity against cancer cells while maintaining a minimal systemic side effects represents a promising therapeutic approach. Therefore, the aim of this study was to develop an efficient gold nanocarrier for the targeted delivery of the anticancer agent everolimus to Caco-2 cells.
