The viscoelasticity of a biofilm's EPS (extracellular-polymeric-substance) matrix conveys protection against mechanical challenges, but adaptive responses of biofilm inhabitants to produce EPS are not well known. Here, we compare the response of a biofilm of an EPS producing (ATCC 12600) and non-EPS producing (5298) Staphylococcus aureus strain to fluid shear and mechanical challenge. Confocal-Laser-Scanning-Microscopy confirmed absence of calcofluorwhite-stainable EPS in biofilms of S. aureus 5298. ATR-FTIR spectroscopy combined with tribometry indicated that the polysaccharide production per bacterium in the initial adhering layer was higher during growth at high shear than at low shear and this increased EPS production extended to entire biofilms, as indicated by tribometrically measured coefficients of friction (CoF)...

Recovery of everyday premorbid function is a primary goal in the treatment of depression. Measurement of function is an important part of achieving this goal. A multitude of scales have been used to measure function in depression, reflecting the complex, multifaceted nature of functioning. Currently, however, there are no evidence-based guidelines to assist the researcher or clinician in deciding which instruments are best suited to measure function in late-life depression (LLD). Thus, the aims of this study are to 1) systematically review and identify the instrumental activities of daily living and social functioning assessment instruments used in the LLD literature; 2) identify and appraise the measurement properties of these instruments; and 3) suggest factors for LLD researchers and clinicians to consider when selecting functional assessment instruments and make pertinent recommendations...

Various forms of intraoperative computer-assisted navigation technologies exist, and have consistently been shown to improve pedicle screw accuracy. However, the overall clinical effects of inaccurate pedicle screw placement have been debated. We examined the clinical effects of improved pedicle screw accuracy with computer navigation technology in reducing complication rates in patients undergoing multi-level spinal fusion. We retrospectively reviewed the ACS-NSQIP registry utilizing Current Procedural Terminology (CPT) codes 22843 + 22844 to identify patients undergoing spinal instrumentation of greater than 7 levels, as well as the CPT code 61783 to denote the use of intraoperative computer-assisted navigation...

REVIEW
Umberto Albert, Alessandra Baffa, Giuseppe Maina
The term accommodation has been used to refer to family responses specifically related to obsessive-compulsive (OC) symptoms: it encompasses behaviors such as directly participating in compulsions, assisting a relative with obsessive-compulsive disorder (OCD) when he/she is performing a ritual, or helping him/her to avoid triggers that may precipitate obsessions and compulsions. At the opposite side, family responses to OCD may also include interfering with the rituals or actively opposing them; stopping accommodating OC symptoms or actively interfering with their performance is usually associated with greater distress and sometimes even with aggressive behaviors from the patients...
