Modulation of the complement system in monocytes contributes to tuberculosis-associated immune reconstitution inflammatory syndrome.

Tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) is a common complication in HIV-TB co-infected patients receiving combined antiretroviral therapy (cART). This study investigated a putative contribution of monocytes to the development of TB-IRIS.

A new parameterization of Johnson's SB distribution with application to fitting forest tree diameter data

The SB distributional model of Johnson's 1949 paper was introduced by a transformation to normality, that is, z ~ N(0, 1), consisting of a linear scaling to the range (0, 1), a logit transformation, and an affine transformation, z = γ + δu. The model, in its original parameterization, has often been used in forest diameter distribution modelling. In this paper, we define the SB distribution in terms of the inverse transformation from normality, including an initial linear scaling transformation, u = γ′ + δ′z (δ′ = 1/δ and γ′ = �γ/δ). The SB model in terms of the new parameterization is derived, and maximum likelihood estimation schema are presented for both model parameterizations. The statistical properties of the two alternative parameterizations are compared empirically on 20 data sets of diameter distributions of Changbai larch (Larix olgensis Henry). The new parameterization is shown to be statistically better than Johnson's original parameterization for the data sets considered here.

Tiflocolitis syndrome acute for "Klebsiella" sp. in a spanish pure breed horse. A case report

Were study a horse (Equus caballus), Purebred Spanish Horse, 6 years old, intact male sex, weight about 550kg, from equestrian center in Fregenal Sierra-Extremadura, Spain. History of acute diarrhea, are apply conventional treatment (hydration, anti-inflammatory and antibiotic). Physical examination showed severe profuse, fetid diarrhea deep red, tachypnea. The physiological parameters were: heart rate 60 bpm, respiratory rate 39 rpm and mucous cyanotic. Temperature: 40°C. Hematological examination showed severe leucopenia, decreased total serum protein, albumin and globulin also diminished. Serum chemistry evidenced severe hyponatremia and hypokalemia, with high levels of chlorine indicating metabolic acidosis. A stool analysis, which was negative and showed no eggs or larvae in the samples studied was performed. The microbial culture allowed the isolation of Klebsiella sp. and susceptibility testing showed sensitivity to ampicillin, Cetafzidine, Ciprofloxacin, Cefepine, gentamicin, imipenem, meropenem, Piperaciclina, piperacillin / tazobactam and trimethoprim sulfa resistance. The horse presented systemic complications associated with endotoxemia and death 36 hours after the onset of diarrhea. At necropsy, severe bleeding was observed enterotiflocolitis. The histological sections showed proliferative enteritis characterized by lymphocyte and mononuclear inflammatory infiltrate plasmocytorious mucosa and submucosa, coagulation necrosis, bacteria and short rod type morphology with no specific grouping. In conclusion a case of acute syndrome enterotiflocolitis reported Klebsiella sp. on a horse Purebred Spanish.
