Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome defined by clinical and laboratory criteria. Current criteria were created to identify patients with familial hemophagocytic lmyphohistiocytosis in immediate need of immunosuppressive therapy. However, these criteria also identify patients with infection-associated hemophagocytic inflammatory states lacking genetic defects typic...
By using averaging functions, several new oscillation criteria are established for the half-linear damped differential equation-2-2-2-2 r(t) (x) +p(t) |x| x,r(t) (x) +q(t)|x| x=0, dx dx dx dx dt dt dt dt α α α α ψ ϕ ψ ⎛ ⎞ ⎛ ⎞ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎝ ⎠ ⎝ ⎠ and the more general equation-2-2 r(t) (x) +p(t) g(x),r(t) (x) +q(t)g(x)=0, d dx dx dx dx dt dt dt dt dt α α ψ ϕ ψ ⎛ ⎞ ⎛ ⎞ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎜ ⎟ ⎝ ⎠ ⎝ ⎠ ...
and Applied Analysis 3 In 2008, Rogovchenko and Tuncay 13 established new oscillation criteria for secondorder nonlinear differential equations with damping term ( r t x′ t )′ p t x′ t q t f x t 0, 1.6 without an assumption that has been required in related results reported in the literature over the last two decades. Motivated by the ideas in 12, 13 , by introducing a Parameter β ≥ 1, we will ...
AIMS The Brugada criteria proposed to distinguish between regular, monomorphic wide QRS complex tachycardias (WCT) caused by supraventricular (SVT) and ventricular tachycardia (VT) have been reported to have a better sensitivity and specificity than the traditional criteria. By incorporating two new criteria, a new, simplified algorithm was devised and compared with the Brugada criteria. METH...

Electrocardiogram (ECG)is widely used for detection of left ventricular hypertrophy (LVH). For the detection of LVH several different criteria have been used. These criteria have different sensitivity and selectivity, which widely varies from 22% to 54% sensitivity and 100%to 85%specificity respectively. Different LVH criteria has different results of LVH. The aim of the present study was to de...
P a t i e n t s 592 patients (mean age 75 y, 53% men) who met clinical criteria for probable vascular dementia or possible AD with radiologic evidence of cerebrovascular disease. Additional inclusion criteria included a score of 10 to 25 on the Mini-Mental State Examination and ≥ 12 on the Alzheimer Disease Assessment Scale Cognitive subscale (ADAS-COG). Exclusion criteria included evidence of ...
In this paper, existence criteria of three positive solutions to the followimg p-Laplacian functional dynamic equation on time scales { [ Φp(u (t)) 5 + a(t)f(u(t), u(μ(t))) = 0, t ∈ (0, T ) , u0(t) = φ(t), t ∈ [−r, 0] , u(0)−B0(u (η)) = 0, u(T ) = 0, are established by using the well-known Five Functionals Fixed Point Theorem.
We obtain some oscillation criteria for the Hamiltonian difference system (AY{t) = B{t)Y{t+\) + C{t)Z{t), I AZ{t) = -A{t)Y{t + 1) B*{t)Z{t), where A, B, C, Y, Z are dxd matrix functions. As a corollary, we establish the validity of an earlier conjecture for a second-order matrix difference system.
The oscillation criteria for forced nonlinear fractional difference equation of the form ∆x(t) + f1(t, x(t+ α)) =v(t) + f2(t, x(t+ α)), t ∈ N0, 0 < α ≤ 1, ∆x(t)|t=0 =x0, where ∆α denotes the Riemann-Liouville like discrete fractional difference operator of order α is presented.
