Comparison of mesa and device diameter variation in double wafer-fused multi quantum-well, long-wavelength, vertical cavity surface emitting lasers
No full textLong-wavelength vertical-cavity surface-emitting lasers (LW-VCSELs) have profound advantages compared to traditional edge-emitting lasers offering improved properties with respect to mode selectivity, fibre coupling, threshold currents and integration into 2D arrays or with other electronic devices. Its commercialization is gaining momentum as the local and access network in optical communication system expand. Numerical modeling of LW-VCSEL utilizing wafer-fused InP-based multi-quantum wells (MQW) and GaAs-based distributed Bragg reflectors (DBRs) is presented in this paper. Emphasis is on the device and mesa/pillar diameter design parameter comparison and its effect on the device characteristics

P.S.: Further Thoughts from a Lifetime of Listening
No full textThe pieces in P.S. reflect Studs’s wide-ranging interests and travels, as well as his abiding connection to his hometown, Chicago. Here we have a fascinating conversation with James Baldwin, possibly Studs’s finest interview with an author; pieces on the colorful history and culture of Chicago; vivid portraits of Studs’s heroes and cohorts (including an insightful and still timely interview with songwriter Yip Harburg, known for his “Brother, Can You Spare a Dime”); and the transcript of Studs’s famous broadcast on the Depression, the very moving essence of what was to become Hard Times.https://corescholar.libraries.wright.edu/dlpp_all/1204/thumbnail.jp

Long-term evolution of calcific tendinitis of the rotator cuff : clinical and radiological evaluation 10 years after diagnosis
No full textBackground: Calcific tendinitis of the shoulder has a tendon involvement that could evolve to rotator cuff tear and shoulder osteoarthritis. This study aimed to evaluate the prevalence of glenohumeral osteoarthritis and rotator cuff tears in patients affected by calcific tendinitis at a minimum follow-up of 10 years after diagnosis.
Methods: Patients diagnosed with calcific tendinitis of the shoulder with a minimum follow-up of 10 years were contacted and invited for a clinical and radiological evaluation. Information on the demographics, affected and dominant side, bilateral shoulder pain, type of treatment, habits, systemic or musculoskeletal diseases, reoperation of the index shoulder, and subjective satisfaction was collected. The clinical evaluation was performed using Constant–Murley score (CMS), American Shoulder and Elbow Surgeons Score (ASES), and numerical rating scale (NRS); isometric strength in forwarding flexion and abduction was also measured. Each patient also underwent an ultrasound examination to evaluate rotator cuff tendon integrity and a shoulder radiograph to evaluate osteoarthritis.
Results: Seventy-nine patients were available for a phone interview, and 35 agreed to be examined. The mean age was 58.89 (± 7.9) years at follow-up. The prevalence of glenohumeral osteoarthritis was 17.14% in the study population, with significant progression in 14.29% of the cases, without rotator cuff full-thickness tears. x-Ray examination showed residual calcifications in 31 patients, with a mean diameter of 5.54 mm. In 30 cases, there was a reduction of the diameter; in 4 cases, the calcification increased in size; and in 1 case, the size did not change. The mean ASES score was 74.1 (± 22.7) in the group with calcifications larger than 2 mm and 89.4 (± 8.2) in patients with smaller calcifications (p = 0.08) without correlation with the type of treatment performed.
Conclusions: Calcific tendinitis is a self-resolving disease without rotator cuff tears at long-term follow-up or degenerative glenohumeral progression

Platelet-rich plasma does not improve clinical results in patients with rotator cuff disorders but reduces the retear rate. A systematic review and meta-analysis
No full textPurpose: To assess whether the use of Platelet-rich plasma (PRP) produces a clinical benefit in patients with rotator cuff disorders, treated either conservatively or surgically. Methods: A systematic review was performed according to PRISMA guidelines on three databases (PubMed, Cochrane Library, Web of Science) to identify randomised controlled trials (RCTs) on the use of PRP in patients with rotator cuff disorders, treated either conservatively or surgically. A meta-analysis was performed on articles reporting results for Constant, UCLA, VAS, SST scores and retear rate. The RoB 2.0 and the modified Coleman Methodology Score were used to assess methodological quality. Results: A total of 36 RCTs (20 surgical, 16 conservative) were included, for a total of 2,443 patients. Conservative treatment showed high heterogeneity and no clear consensus in favour of PRP. The meta-analysis of the studies with surgical treatment showed no benefit in using PRP in any of the clinical outcomes, either at the short or medium/long-term follow-up. However, the retear rate was lower with PRP augmentation (p < 0.001). The overall quality of the studies was moderate to high, with the surgical studies presenting a lower risk of bias than the conservative studies. Conclusion: The use of PRP as augmentation in rotator cuff surgical repair significantly reduces the retear rate. However, no benefits were documented in terms of clinical outcomes. PRP application through injection in patients treated conservatively also failed to present any clear advantage. While there are many studies in the literature with several RCTs of moderate to high quality, the high heterogeneity of products and studies remains a significant limitation to fully understanding PRP potential in this field.

The presence of gastroesophageal reflux disease increases the risk of developing post-operative shoulder stiffness after arthroscopic rotator cuff repair
No full textPurpose: Postoperative shoulder stiffness (SS) after arthroscopic rotator cuff (RC) repair has been reported with variable incidence and numerous preoperative risk factors have been described. This prospective study aims to document the incidence of postoperative SS and to evaluate the role of preoperative risk factors in the development of this complication, with special focus on the role of gastroesophageal reflux disease (GERD).
Methods: Preoperative risk factors for SS were prospectively evaluated in 237 consecutive patients undergoing single-row arthroscopic RC repair. The presence of GERD was evaluated with the GerdQ diagnostic tool. Postoperative SS was diagnosed according to the criteria described by Brislin and colleagues in 2007.
Results: The incidence of postoperative SS was 8.02%. The presence of GERD was significantly associated with development of postoperative SS (OR: 5.265; 95% CI, 1.657-1.731; p=0.005). Older age (OR: 0.896; 95% CI, 0.847-0.949; p<0.001), male gender (OR: 0.126; 95% CI, 0.0252-0.632; p=0.012) and number of pregnancies (OR: 0.47; 95% CI, 0.228-0.967; p=0.040) emerged as protective factors.
Conclusions: The presence of GERD significantly influences the development of postoperative SS after single-row arthroscopic RC repair. An underlying a specific pro-inflammatory condition, characterized by increased expression of TNF-α and TGF-β, and disorders in retinoid metabolism are hypothesis which could explain this previously unknown association. The documented incidence of postoperative SS falls among previously reported ranges, with females significantly more affected than men
