Injection of an allodermal matrix and leukocyte-rich platelet-rich plasma mixture improved the tendon integrity in cases of full-thickness common extensor tendon tears of the elbow: Two case reports.

Rationale: Lateral epicondylitis, commonly known as tennis elbow, is a chronic condition characterized by tendinosis at the insertion site of the lateral epicondyle. Various treatment methods are available, ranging from conservative to surgical options for refractory lateral epicondylitis. Recently, platelet-rich plasma (PRP) injections have shown effectiveness for treating this condition.

Effect of Endurance Exercise Training on Gut Microbiota and ER Stress.

Regular exercise as part of one's lifestyle is well-recognized for its beneficial effect on several diseases such as cardiovascular disease and obesity; however, many questions remain unanswered regarding the effects of exercise on the gut environment. This study aimed to investigate the impact of long-term endurance exercise on modulating inflammation and endoplasmic reticulum (ER) stress. Fifteen-week-old male Sprague-Dawley (SD) rats were subjected to six months of endurance treadmill training, while age-matched controls remained sedentary.

Comparison of Locking Plate Fixation and Coracoclavicular Ligament Reconstruction for Neer Type 2B Distal Clavicle Fractures.

Background: There remains no consensus regarding which repair technique provides the most optimal results for unstable distal clavicle fractures.

Purpose: To compare radiologic and clinical outcomes between locking plate fixation and anatomic coracoclavicular (CC) ligament reconstruction for patients with unstable distal clavicle fractures.

Study Design: Cohort study; Level of evidence, 3.

Biceps-incorporating rotator cuff repair with footprint medialization in large-to-massive rotator cuff tears.

Purpose: In large-to-massive rotator cuff tears (MRCTs), incorporating the long head of the biceps tendon (LHBT) with arthroscopic partial rotator cuff and margin convergence can improve clinical outcomes and preserve the acromio-humeral interval (AHI) during mid-term follow-up. The purpose of this study was to evaluate mid-term clinical and radiological outcomes of arthroscopic biceps-incorporating rotator cuff repair with partial release of the LHBT and footprint medialization through the Neviaser portal in MRCTs.

Methods: This study enrolled 107 patients (38 males and 69 females, mean age: 64.

Influence of increased pain sensitivity on patient-reported outcomes following total knee arthroplasty.

Purpose: The purpose of this study was to discover whether increased pain sensitivity was associated with postoperative pain and patient-reported outcome measures (PROMs) after total knee arthroplasty (TKA).

Methods: Pain sensitivity was evaluated preoperatively using a pain sensitivity questionnaire (PSQ). Resting, walking, nighttime, and average pain visual analog scale (VAS) were measured before surgery and 6 weeks, 3 months, 6 months, and 1 year after surgery.

Bone Mineral Density and Osteoporotic Vertebral Fractures in Traditional, Unassisted, Free-Diving Women (Haenyeos).

Background: Water pressure and muscle contraction may influence bone mineral density (BMD) in a positive way. However, divers experience weightlessness, which has a negative effect on BMD. The present study investigated BMD difference in normal controls and woman free-divers with vertebral fracture and with no fracture.

Reversal of serologic, immunologic, and histologic dysfunction in mice with systemic lupus erythematosus by long-term serial adipose tissue-derived mesenchymal stem cell transplantation.

Objective: To investigate the efficacy of human adipose tissue-derived mesenchymal stem cell (AD-MSC) transplantation in systemic lupus erythematosus (SLE) and to determine the optimal transplantation window for stem cells either before or after disease onset.

Methods: (NZB×NZW)F1 mice with SLE were administered human AD-MSCs (5×10(5)) intravenously every 2 weeks from age 6 weeks until age 60 weeks, while the control group received saline vehicle on the same schedule. Another experiment was carried out with a different initiation time point for serial transplantation (age 6 weeks or age 32 weeks).

Safety of intravenous infusion of human adipose tissue-derived mesenchymal stem cells in animals and humans.

Adipose tissue-derived mesenchymal stem cells (AdMSCs) represent an attractive and ethical cell source for stem cell therapy. With the recent demonstration of MSC homing properties, intravenous applications of MSCs to cell-damaged diseases have increased. In the present study, the toxicity and tumorigenicity of human AdMSCs (hAdMSCs) were investigated for clinical application.

Transplantation of CTLA4Ig gene-transduced adipose tissue-derived mesenchymal stem cells reduces inflammatory immune response and improves Th1/Th2 balance in experimental autoimmune thyroiditis.

Background: Autoimmune thyroiditis is one of common organ-specific autoimmune disease. The aim of this study was to observe the effect of adipose tissue derived mesenchymal stem cells (ATMSC) and CTLA4Ig gene-transduced ATMSC on autoimmune thyroiditis.

Methods: Experimental autoimmune thyroiditis was induced by immunization with thyroglobulin.
