A Virtual Repository of Neurosurgical Instrumentation for Neuro-engineering Research and Collaboration.

The advancements in microscopy and more recently in neuro-endoscopy, have revolutionized the field of neurosurgery. Hand-held neurosurgical instruments are integral components of these procedures. However, these instruments have many limitations such as deprived ergonomics, constrained maneuverability and limited degrees of freedom. Hence, a need for developing better instruments is commonly felt by neurosurgeons. Also, the focus of modern neurosurgical training is now shifting towards simulation models. Th...

Is the Human Brain Capable of Controlling Seven Degrees of Freedom?

Conventional rigid laparoscopic instruments offer five degrees of freedom (DOF). Robotic instruments add two independent DOFs allowing unconstrained directional steering. Several nonrobotic instruments have been developed with the additional DOFs, but with these devices, surgeon's wrist movements are not intuitively transmitted into tip movements. In this study, a new articulated instrument has been evaluated. The aim of the study was to compare learning curves and performances of conventional laparoscopic ...

Objective The aim of this study was to evaluate the influence of torsional preloading on the cyclic flexural fatigue resistance of thermally treated NiTi instruments. Material and Methods Ten new instruments New Hyflex CM (HF 30.06; Coltene/Whaladent Inc.), Typhoon CM (TYP 30.06; Clinician's Choice Dental Products) and Vortex Blue (VB 30.06; Dentsply Tulsa Dental) were chosen, based on geometry and specific characteristics of the manufacturing process. The new instruments of each system were tested in a ben...

Systematic review and critical appraisal of child abuse measurement instruments.

Child abuse is a major public health concern and a strong predictor of adult psychopathology. However, a consensus on how best to measure child abuse is not evident. This review aimed to critically appraise the methodological quality and measurement properties of published child abuse measures, examined the strength of evidence of these instruments for research use using the COnsensus-based Standards for the selection of health Measurement InstrumeNts (COSMIN) checklist and determined which measures were ca...

What Are the MCIDs for PROMIS, NDI, and ODI Instruments Among Patients With Spinal Conditions?

As new Patient-Reported Outcomes Measurement Information System (PROMIS) instruments are incorporated into clinical practice, determining how large a change on these instruments represents a clinically relevant difference is important; the metric that describes this is the minimum clinically important difference (MCID). Prior research on MCIDs of the Neck Disability Index (NDI) and Oswestry Disability Index (ODI) has produced values ranging from 5 to 10 points, but these measures have not been presented in ...

Effect of Using Ergobrass Ergonomic Supports on Postural Muscles in Trumpet, Trombone, and French Horn Players.

Though ergonomic supports are widely used for many groups of instruments, they are rare for brass instruments, despite the instruments' considerable weight. Musculoskeletal injury and postural problems are common among this group, and so, both adult and young players are likely to benefit from supports that reduce the load placed on the body. This study assessed the effects on postural muscle activity of a recently developed range of supports (Ergobrass) that use a rod to transfer the weight of the instrume...

Classification and cyclic fatigue evaluation of new kinematics for endodontic instruments.

This study evaluated the effect of new motions of the motor TriAuto ZX2 on the cyclic fatigue of endodontic instruments. Vortex Blue 35.06 instruments were divided into four groups (n = 10) and tested for fatigue in a curved artificial canal (90° and 2 mm radius) using the following motions: continuous rotation (CR), Optimum Torque Reverse (OTR) set at 180° and the Optimum Glide Path (OGP), which was tested at 90° and 240°. The time to fracture (TTF) and the lengths of the fractured fragments were re...

Methodology for evaluating and comparing flow cytometers: A multisite study of 23 instruments.

We demonstrate improved methods for making valid and accurate comparisons of fluorescence measurement capabilities among instruments tested at different sites and times. We designed a suite of measurements and automated data processing methods to obtain consistent objective results and applied them to a selection of 23 instruments at nine sites to provide a range of instruments as well as multiple instances of similar instruments. As far as we know, this study represents the most accurate methods and result...

Data on U.S. state-level electric vehicle policies, 2010-2015.

This data set documents the duration and value of U.S. state and local electric vehicle (EV) policies in effect from 2010 to 2015. Though the focus is on policies at the state-level, local government and electric utility policies are documented when they collectively cover a majority of the state׳s population or electricity customers. Data were collected first from the Alternative Fuel Database Center (AFDC), then supplemented with information taken from more than 300 government (state, city, and county) a...

Comparative responsiveness of generic versus disorder-specific instruments for depression: An assessment in three longitudinal datasets.

Routine outcome monitoring (ROM) may enhance individual treatment and is also advocated as a means to compare the outcome of different treatment programs or providers. There is debate on the optimal instruments to be used for these separate tasks.

Spanish validation of the Sexual Addiction Screening Test.

Sexual addiction is a pathological behavior characterized by a combination of excessive sexual desire and impaired ability to control it. Its incidence ranges between 1.2% and 32.2%, although this number may vary depending on the screening tool used. This wide variability is largely due to the use of non-validated instruments (e.g., structural validity relying on exploratory analyses, instruments translated without an additional validation process, or instruments validated in another format). To deal with ...

Nickel-titanium instruments in endodontics: a concise review of the state of the art.

The introduction of automated instrumentation in endodontics represented a major advance in progress for this specialty, with improvements in the quality and predictability of root canal preparation and a significant reduction in procedural errors. In recent years, endodontic instruments have undergone a series of changes brought about by modifications in design, surface treatments, and thermal treatments. In addition, new movements have also been incorporated to offer greater safety and efficiency, optimiz...

Do pain measurement instruments detect the effect of pain-reducing interventions in neonates? A systematic review on responsiveness.

The effectiveness of pain-reducing interventions in newborns can only be determined if pain measurement instruments are responsive; i.e. able to detect a decrease in pain intensity after the pain-reducing intervention. This review assesses the methodological quality of studies on this measurement property - the responsiveness. We searched the literature published until January 2018 for validation studies of pain measurement instruments focusing on responsiveness to pain-reducing treatment in neonates. Metho...

Screening wavelengths with consistent and stable signals to realize calibration model transfer of near infrared spectra.

Measurement environmental changes and spectral signal differences among multi-spectrometers may lead to big error in the process of transferring the model of near infrared (NIR) spectra to secondary instruments. Basing on the common sense, NIR calibration models could be shared directily among multi-instruments, if they were built on the wavelengths at which the spectral signals of secondary instruments are stable and well consistent with the primary's. Present work advanced a method named as screening wave...

Disease activity assessment of rheumatic diseases during pregnancy: a comprehensive review of indices used in clinical studies.

Pregnancy requires a special management in women with inflammatory rheumatic diseases (RDs), with the aim of controlling maternal disease activity and avoiding fetal complications. Despite the heterogeneous course of RDs during pregnancy, their impact on pregnancy largely relates to the extent of active inflammation at the time of conception. Therefore, accurate evaluation of disease activity is crucial for the best management of pregnant patients. Nevertheless, there are limitations in using conventional m...
