Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Understanding Therapeutic Equivalence in Epilepsy

CNS Spectrums, 2010
ABSTRACTThe issues surrounding generic drug substitution in patients with epilepsy are complex.The substitution of one formulation of an antiepileptic drug (AED) for another is controversial. Well-reasoned and defensible cases can be made both for and against such substitution.

The therapeutic equivalence of complex drugs

Regulatory Toxicology and Pharmacology, 2011
When the patent of a small molecule drug expires generics may be introduced. They are considered therapeutically equivalent once pharmaceutical equivalence (i.e. identical active substances) and bioequivalence (i.e. comparable pharmacokinetics) have been established in a cross-over volunteer study.

Therapeutic equivalency of two lidocaine preparations

American Journal of Health-System Pharmacy, 1976
Twenty-five volunteers were studied as to the onset and duration of action of two commercial brands of lidocaine. One and two percent concentrations of the preparations were tested intradermally using a double-blind, cross-over protocol. Both needle-drop and electrical stimulation techniques were employed as the source of pain stimulus. Five additional

GENERIC DRUGS AND THERAPEUTIC EQUIVALENCE

JAMA: The Journal of the American Medical Association, 1968
In recent years, there has developed the belief that nonproprietary or generic drugs are much cheaper than, and as effective as, trade-named items. This belief has led to a widespread demand that prescribing and use of generic drugs be encouraged. Studies conducted by impartial groups such as the Medical Letter on Drugs and Therapeutics have applied ...

Therapeutic equivalence: fallacies and falsification

Statistics in Medicine, 2003
AbstractThe number of studies designed specifically to demonstrate therapeutic equivalence or alternatively non‐inferiority of pharmaceutical treatments has increased dramatically in recent years, during which time awareness of the methodological issues has increased. Regulatory authorities have been quick to recognize the need for specific support and

Therapeutic equivalence investigations: statistical considerations

Statistics in Medicine, 1998
Therapeutic equivalence studies still present problems to regulatory reviewers from many perspectives. This paper is intended to discuss some of these concerns from the statistical viewpoint. There are, however, also some newer approaches which may be particularly useful for the investigation of therapeutic equivalence.
