Impact of Work-Related Problems on the Outcomes of Rotator Cuff Repairs: A Retrospective Comparative Study of Patients With and Without Work-Related Claims.

Background: Rotator cuff syndrome is a common cause of medical appointments and surgeries. The aim of this study is to compare the clinical outcomes of patients with work-related problems who underwent arthroscopic repair of full-thickness rotator cuff tears (RCTs) versus those without work-related or social security claims.

Methods: A retrospective cohort study comparing the outcomes of American Shoulder and Elbow Surgeons (ASES) and University of California at Los Angeles Shoulder Rating (UCLA) scores 24 months after arthroscopic repair of full-thickness RCTs of patients with and without work-related problems was performed.

Latarjet procedure: open with screws or arthroscopic with cortical buttons? A retrospective cohort comparison of outcomes and complications.

Background: The original Latarjet-Patte procedure is a reliable technique to treat traumatic anterior shoulder instability. However, attempts to reduce possible complications have led to the emergence of modified techniques. More prominent among them are the arthroscopic approach and the use of cortical buttons for coracoid fixation.

Predictive Factors for the Healing of Rotator Cuff Repairs.

Introduction: Rotator cuff tears (RCTs) are a significant cause of shoulder pain. Rotator cuff repair is common, but healing failure is frequent and the reasons for the retear are still unclear.

Objective: This study aimed to determine if specific preoperative factors related to patients and tears affect the structural outcome after rotator cuff repair.

REASSESSMENT OF FATTY INFILTRATION BY MAGNETIC RESONANCE TEN YEARS AFTER ROTATOR CUFF INJURY REPAIR.

Unlabelled: Quantitative assessments of rotator cuff muscle changes after successful tendon repair are scarce. On the other hand, semiquantitative and subjective assessments are more abundant, but their findings are controversial. One hypothesis about this divergence is that there is an immediate decrease in the proportion of fatty infiltration after surgical repair.

Charge-Sign Dependent Cosmic-Ray Modulation Observed with the Calorimetric Electron Telescope on the International Space Station.

We present the observation of a charge-sign dependent solar modulation of galactic cosmic rays (GCRs) with the Calorimetric Electron Telescope onboard the International Space Station over 6 yr, corresponding to the positive polarity of the solar magnetic field. The observed variation of proton count rate is consistent with the neutron monitor count rate, validating our methods for determining the proton count rate. It is observed by the Calorimetric Electron Telescope that both GCR electron and proton count rates at the same average rigidity vary in anticorrelation with the tilt angle of the heliospheric current sheet, while the amplitude of the variation is significantly larger in the electron count rate than in the proton count rate.

Direct Measurement of the Cosmic-Ray Helium Spectrum from 40 GeV to 250 TeV with the Calorimetric Electron Telescope on the International Space Station.

We present the results of a direct measurement of the cosmic-ray helium spectrum with the CALET instrument in operation on the International Space Station since 2015. The observation period covered by this analysis spans from October 13, 2015, to April 30, 2022 (2392 days). The very wide dynamic range of CALET allowed for the collection of helium data over a large energy interval, from ∼40  GeV to ∼250  TeV, for the first time with a single instrument in low Earth orbit.

Allograft-enhanced latissimus dorsi transfer is better than the conventional technique for irreparable posterosuperior rotator cuff tears. A retrospective matched cohort.

Purpose: Latissimus dorsi tendon (LDT) transfer (LDTT) to the greater tuberosity to treat irreparable posterosuperior rotator cuff tears (RCTs) in young active patients has been shown to have up to 36% of clinical failures, most of them happening because of either deltoid origin disruption or post-operative transfer rupture from the greater tuberosity. In an attempt to simultaneously prevent both complications, a modified technique includes the following adaptations to the original technique: reinforcement and augmentation of the LDT with a tendinous allograft, enabling the use of a single deltopectoral approach. The aim of this study is to compare mid-term outcomes of the traditional LDTT technique with this modified transfer.

Observation of Spectral Structures in the Flux of Cosmic-Ray Protons from 50 GeV to 60 TeV with the Calorimetric Electron Telescope on the International Space Station.

A precise measurement of the cosmic-ray proton spectrum with the Calorimetric Electron Telescope (CALET) is presented in the energy interval from 50 GeV to 60 TeV, and the observation of a softening of the spectrum above 10 TeV is reported. The analysis is based on the data collected during ∼6.2  years of smooth operations aboard the International Space Station and covers a broader energy range with respect to the previous proton flux measurement by CALET, with an increase of the available statistics by a factor of ∼2.

Comparative Clinical Evaluation of Two Techniques of Arthroscopic Treatment of Partial Articular Rotator Cuff Tears.

 To evaluate the clinical results of patients submitted to arthroscopic treatment of partial lesion of the articular part of the rotator cuff by transtendon suture techniques and after completing the lesion and to compare the postoperative recovery time of the two techniques.  Retrospective study based on the identification of all cases with partial lesion of the articular part of the rotator cuff submitted to arthroscopic treatment from October 1999 to December 2016 at the Shoulder and Elbow Group of our institution. Thirty-nine patients were included and divided into two groups: those who underwent the transtendon technique and those in whom the lesion was completed.

Current Options in Tendon Transfers for Irreparable Posterosuperior Rotator Cuff Tears.

Massive irreparable posterosuperior rotator-cuff tears are debilitating lesions that usually require surgical treatment. Even though there is no consensus regarding the best surgical technique, tendinous transfers around the shoulder are the most commonly performed procedures. The latissimus dorsi tendon remains the most commonly used, but different modifications to the original technique have been shown to minimize complications and to improve functional results and satisfaction.

Search for Electron Antineutrino Appearance in a Long-Baseline Muon Antineutrino Beam.

Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events.

Latissimus Dorsi Tendon Transfer using Tendinous Allograft for Irreparable Rotator Cuff Lesions: Surgical Technique.

Latissimus dorsi transfer around the shoulder is the most frequently used surgical technique to treat young patients with irreparable posterosuperior rotator cuff lesions. This technique, as initially described and popularized by Gerber et al., has two main drawbacks that may predispose to complications and unsatisfactory functional results: 1) postoperative rupture of the origin of the deltoid, as its detachment from the acromion is necessary during the superior approach to the shoulder; and 2) postoperative rupture of the transferred tendon.

Direct Measurement of the Cosmic-Ray Proton Spectrum from 50 GeV to 10 TeV with the Calorimetric Electron Telescope on the International Space Station.

In this paper, we present the analysis and results of a direct measurement of the cosmic-ray proton spectrum with the CALET instrument onboard the International Space Station, including the detailed assessment of systematic uncertainties. The observation period used in this analysis is from October 13, 2015 to August 31, 2018 (1054 days). We have achieved the very wide energy range necessary to carry out measurements of the spectrum from 50 GeV to 10 TeV covering, for the first time in space, with a single instrument the whole energy interval previously investigated in most cases in separate subranges by magnetic spectrometers (BESS-TeV, PAMELA, and AMS-02) and calorimetric instruments (ATIC, CREAM, and NUCLEON).
