Objective:To examine the effect of the COVID-19 virus,especially the Omicron variant,on hematological parameters of hospitalized pediatric patients during the COVID-19 ***:Medical records of pediatric COVID-19 patients hospitalized at Kartal Dr.Lütfi K?rdar City Hospital in Istanbul,Turkey,between March 2020 and May 2022 were retrospectively reviewed to analyze data regarding demographics,SARS-Co V-2 infection polymerase chain reaction(PCR)test results,reversetranscriptase(RT)-PCR for other respiratory agents,duration of hospital stay,and hematological and biochemical laboratory ***:Out of 467 children with a confirmed diagnosis of SARSCo V-2 infection,94(20.1%)had Omicron infection and 373(79.9%)were infected with other variants;the Omicron group had younger patients than the remaining samples(P<0.001).The most frequent clinical symptoms in all children were cough(53.5%)and fever(32.3%),followed by vomiting(20.8%).Lung involvement in the Omicron group(10.6%)was significantly lower than in the remaining samples(29.8%)(P<0.001).Hemoglobin and lymphocyte levels were lower in the Omicron-infected group(both P<0.001),while prothrombin time,activated partial thromboplastin time,international normalized ratio,and D-dimer levels were significantly higher in this group(P<0.001,P<0.001,P<0.001,and P=0.023,respectively).In terms of lung involvement,those with lung involvement were significantly older(P<0.001).Conclusions:Although lung involvement was less common with Omicron infection,this group had greater hematological system involvement,such as anemia,lymphopenia,D-dimer elevation,and coagulation disorders.

General quantum gravity arguments predict that Lorentz symmetry might not hold exactly in nature. This has motivated much interest in Lorentz breaking gravity theories recently. Among such models are vector-tensor theories with preferred direction established at every point of spacetime by a fixed-norm vector field. The dynamical vector field defined in this way is referred to as the "aether". In this paper, we put forward the idea of a null aether field and introduce, for the first time, the Null Aether Theory(NAT) — a vector-tensor theory. We first study the Newtonian limit of this theory and then construct exact spherically symmetric black hole solutions in the theory in four dimensions, which contain Vaidya-type non-static solutions and static Schwarzschild-(A)dS type solutions, Reissner-Nordstr?m-(A)dS type solutions and solutions of conformal gravity as special cases. Afterwards, we study the cosmological solutions in NAT:We find some exact solutions with perfect fluid distribution for spatially flat FLRW metric and null aether propagating along the x direction. We observe that there are solutions in which the universe has big-bang singularity and null field diminishes asymptotically. We also study exact gravitational wave solutions — AdS-plane waves and pp-waves — in this theory in any dimension D ≥ 3. Assuming the Kerr-Schild-Kundt class of metrics for such solutions, we show that the full field equations of the theory are reduced to two, in general coupled, differential equations when the background metric assumes the maximally symmetric form. The main conclusion of these computations is that the spin-0 aether field acquires a "mass" determined by the cosmological constant of the background spacetime and the Lagrange multiplier given in the theory.
