Factors associated with employment of powered wheelchair users.

Purpose: To identify correlations between demographic, health-related, environmental factors and the employment status of power wheelchair (PWC) users.

Method: We retrospectively analysed semi-structured interviews with 128 participants, their assistants or family members, and the participant's provided medical records. Participants were adult PWC users who applied for grants in purchasing a new PWC for gaining or keeping employment between 2019-2021 in Mazovian Province, Poland.

Sphenomaxillary Plate: Landmine or Landmark?

Objectives: Sphenomaxillary plate (SMP) is an inconstant bony septum separating the maxillary and sphenoid sinuses. Neglecting the SMP during endoscopic sinus surgery may lead to mistaking the sphenoid sinus for the posterior ethmoid cell with potentially dangerous consequences. However, its proper identification may allow planned sphenoidotomy through the posterior wall of the maxillary sinus or to enlarge transnasal or transethmoidal sphenoidotomy.

What do physiotherapists and physiotherapy students know about autonomic dysreflexia?

Context/objective: Autonomic dysreflexia (AD) is an emergency condition typical for individuals with spinal cord injury (SCI). Adequate health professionals' knowledge of AD is important for the effective and safe rehabilitation of persons with SCI. The purpose of the study is to assess the knowledge of AD in undergraduate and postgraduate physiotherapists.

Three-dimensional computed tomography analysis of frontoethmoidal cells: A critical evaluation of the International Frontal Sinus Anatomy Classification (IFAC).

Objectives: Two major classifications of frontoethmoidal cells, Lee and Kuhn and the IFAC (International Frontal Sinus Anatomy Classification), distinguish anterior, posterior and medial cells. The European anatomical position paper includes also lateral cells. According to the IFAC, anterior cells push the frontal sinus drainage pathway (FSDP) medially, posteriorly or posteromedially.

The Effect of Anti-aging Peptides on Mechanical and Biological Properties of HaCaT Keratinocytes.

Atomic force microscopy (AFM) and fluorescence microscopy was applied to determine the influence of the anti-aging peptides on the morphology and the mechanical properties of keratinocytes. Immortalized human keratinocytes (HaCaT) were treated with two anti-aging bioactive peptides: Acetyl Tetrapeptide-2 and Acetyl Hexapeptide-50 (Lipotec). The AFM measurement of the keratinocyte stiffness were carried after 48 h exposure at an indentation depth of 200 nm.
