Interlaboratory Measurement of Adeno-Associated Virus: Comparative Quantification of Full and Empty Capsids.

Recombinant adeno-associated virus (AAV) is one of the main viral vector-based gene therapy platforms. AAV is a virus consisting of a ≈25 nm diameter capsid with a ≈4.7 kb cargo capacity.

Ankle-Brachial Index Is an Effective Screening Tool for Vascular Injury in Schatzker Type-4 to 6 Tibial Plateau Fractures with Symmetric Pulses.

Background: Schatzker type-4 to 6 tibial plateau fractures most commonly occur when the distal femur is driven through the proximal tibial articular surface. This mechanism of injury can be equivalent to a knee dislocation and carries an increased risk of vascular injury. Our institution screens all Schatzker type-4 to 6 tibial plateau fractures with symmetric pulses for a vascular injury by measuring the ankle-brachial index (ABI).

Formal Physical Therapy Improves PROMIS PF for High Anxiety Patients Following Ankle ORIF.

Objective: To compare outcomes after ankle fracture fixation between those receiving formal physical therapy (PT) vs. no formal PT and those with high vs. low PROMIS anxiety score (AS), and to evaluate the effect of PT in the setting of PROMIS AS scores.

Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Search for the Z Boson Decay to ττμμ in Proton-Proton Collisions at sqrt[s]=13 TeV.

The first search for the Z boson decay to ττμμ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138  fb^{-1}. The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.

The relative branching fraction, with respect to the decay, is measured to be , where the first uncertainty is statistical, the second is systematic, and the third is related to the uncertainties in and .

Observation of Enhanced Long-Range Elliptic Anisotropies Inside High-Multiplicity Jets in pp Collisions at sqrt[s]=13 TeV.

A search for collective effects inside jets produced in proton-proton collisions is performed via correlation measurements of charged particles using the CMS detector at the CERN LHC. The analysis uses data collected at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 138  fb^{-1}. Jets are reconstructed with the anti-k_{T} algorithm with a distance parameter of 0.

Radiographic Accuracy of Identifying Anterolateral Tibial Plafond Involvement in Pronation Abduction Ankle Fractures.

Objectives: To evaluate the incidence of anterolateral tibial plafond involvement in pronation-abduction (PAB) ankle fractures and analyze the accuracy of radiographs in detecting anterolateral tibial plafond involvement, impaction, and predicting the need for direct visualization and an articular reduction.

Design: A multi-institutional retrospective chart review.

Setting: Five Level 1 trauma centers in the United States.

Implementation of a Nurse-Initiated Protocol to Improve Enteral Medication Administration Documentation in Stroke Patients.

BACKGROUND: Medication documentation falls under the "7 rights" of medication administration, but strategies to prevent medication administration documentation errors (MADEs) related to route of administration are underreported in the literature. This study aimed to report the outcomes of a nurse-initiated protocol designed to prevent MADEs and align both actual and documented medication administration routes in hospitalized stroke patients with feeding tubes (FTs). METHODS: This was a retrospective descriptive study conducted at a Comprehensive Stroke Center and large academic medical center in the Western United States.

Changing Epidemiology of Distal Femur Fractures: Increase in Geriatric Fractures and Rates of Distal Femur Replacement.

Introduction: Distal femur fractures (DFFs) are associated with high complication and mortality rates in the elderly. Using the National Inpatient Sample and Medicare data, we describe trends in the incidence of DFFs by fixation type and associated healthcare costs.

Methods: Annual population rates and volume of inpatient DFFs were estimated using Poisson regression with the US Census as a denominator.

Substitutional/positional disorder of biguanide and guanylurea in the structure of a decavanadate complex [(Bg)(HVO)][(HGU)(VO)](HMet)(HO)·8HO.

A hydrated salt of decavanadate containing diprotonated metforminium(2+) (HMet), hydronium (HO) and either neutral biguanide (Bg) or monoprotonated guanylurea (HGU) exhibits a previously seen complex charge-stabilized hydrogen-bonded network [Chatkon et al. (2022). Acta Cryst.

Post-Traumatic Arthritis of the Knee and Ankle.

Post-traumatic osteoarthritis (PTOA) occurs following injury to joints. It accounts for approximately 12% of osteoarthritis and has far-reaching effects on individual patients and social/health care systems. Present work focuses on evaluating the role of the post-traumatic inflammatory response in the development and progression of the disease.

Measurement of Energy Correlators inside Jets and Determination of the Strong Coupling α_{S}(m_{Z}).

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of sqrt[s]=13  TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3  fb^{-1}. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom.

Observation of the ϒ(3S) Meson and Suppression of ϒ States in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The production of ϒ(2S) and ϒ(3S) mesons in lead-lead (Pb-Pb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The ϒ(3S) meson is observed for the first time in Pb-Pb collisions, with a significance above 5 standard deviations. The ratios of yields measured in Pb-Pb and pp collisions are reported for both the ϒ(2S) and ϒ(3S) mesons, as functions of transverse momentum and Pb-Pb collision centrality.
