Mesenteric Thrombosis Complicating Influenza B Infection

To the Editor: A 44-year-old healthy, active man presented to an outside hospital complaining of a 1-day history of fever up to 39�C, muscle aches, sinus pressure, nausea, vomiting, and diarrhea in April 2015. Review of systems was negative for abdominal pain, hematochezia, or melena. A chest radiograph was negative for infiltration, consolidation, edema, or other pathology. Lipase level was 37 U/L (within normal limits). A nasopharyngeal swab antigen test was positive for influenza B, and the patient was discharged on oseltamivir. Three days later, intermittent fevers persisted with chills, nausea, vomiting, and severe abdominal pain. Anorexia developed, and the patient described “something twisting and pulling at [his] insides.” An abdominal computed tomography scan showed extensive superior mesenteric vein thrombosis, which extended into the main portal vein and proximal splenic vein. He was transferred to our facility for transhepatic thrombolysis, which was complicated by intrahepatic hematoma requiring subselective hepatic artery embolization. He recovered completely and was discharged with rivaroxaban. Hematology evaluation was negative for predisposing hypercoagulable conditions including factor II mutation, factor V Leiden, and lupus anticoagulant. Of note, his past medical, surgical, and family history were unrevealing for malignancy, coagulopathy, cirrhosis, pancreatitis, or other prothrombotic states

Phenomenological MSSM interpretation of CMS searches in pp collisions at √s=7 and 8 TeV

Searches for new physics by the CMS collaboration are interpreted in the framework of the phenomenological minimal supersymmetric standard model (pMSSM). The data samples used in this study were collected at root s = 7 and 8 TeV and have integrated luminosities of 5.0 fb(-1) and 19.5 fb(-1), respectively. A global Bayesian analysis is performed, incorporating results from a broad range of CMS supersymmetry searches, as well as constraints from other experiments. Because the pMSSM incorporates several well-motivated assumptions that reduce the 120 parameters of the MSSM to just 19 parameters defined at the electroweak scale, it is possible to assess the results of the study in a relatively straightforward way. Approximately half of the model points in a potentially accessible subspace of the pMSSM are excluded, including all pMSSM model points with a gluino mass below 500 GeV, as well as models with a squark mass less than 300 GeV. Models with chargino and neutralino masses below 200 GeV are disfavored, but no mass range of model points can be ruled out based on the analyses considered. The nonexcluded regions in the pMSSM parameter space are characterized in terms of physical processes and key observables, and implications for future searches are discussed

Search for neutral resonances decaying into a Z boson and a pair of b jets or τ leptons

A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a bb‾ pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb −1 . No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models

Search for a low-mass pseudoscalar Higgs boson produced in association with a bb⁻ pair in pp collisions at √s=8 TeV

A search is reported for a light pseudoscalar Higgs boson decaying to a pair of tau leptons, produced in association with a b (b) over bar pair, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of 8 TeV collected by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 fb(-1). Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a pseudoscalar boson is found and upper limits are set on the product of cross section and branching fraction to tau pairs between 7 and 39 pb at the 95% confidence level. This excludes pseudoscalar A bosons with masses between 25 and 80 GeV, with SM-like Higgs boson negative couplings to down-type fermions, produced in association with bb pairs, in Type II, two-Higgs-doublet models.
