Application of Orofacial Muscle Strength Measurement to Screen for Penetration/Aspiration Risk in Older Adults With Sarcopenia: A Diagnostic Accuracy Study.

Background: Early identification of penetration/aspiration (P/A) risk in older adults with sarcopenia is crucial to prevent complications and maintain quality of life.

Purpose: To evaluate the diagnostic utility of orofacial muscle strength measurements for predicting the risk of P/A in older adults with sarcopenia.

Methods: In this observational and prospective study, we collated consecutive data from community-dwelling older adults diagnosed with sarcopenia at a musculoskeletal disorder clinic.

Junctional Role of Anionic Domain of Mussel Foot Protein Type 4 in Underwater Mussel Adhesion.

Mussel byssi form a robust underwater adhesive system, anchoring to various surfaces in harsh marine environments. Central to byssus is foot protein type 4 (fp-4), a junction protein connecting collagenous threads to proteinaceous plaque. This study investigated an anionic plaque-binding domain of fp-4 (fp-4a) and its interactions with cationic foot proteins (fp-1, fp-5, and fp-151 as model substitutes for fp-2) and metal ions (Ca, Fe, and V).

Canine Stem Cell-derived Exosomes for Lung Inflammation: Efficacy of Intratracheal Intravenous Administration in an Acute Lung Injury Mouse Model.

Background/aim: Acute lung injury (ALI) is an important pathological process in acute respiratory distress syndrome; however, feasible and effective treatment strategies for ALI are limited. Recent studies have suggested that stem cell-derived exosomes can ameliorate ALI; however, there remains no consensus on the protocols used, including the route of administration. This study aimed to identify the appropriate route of administration of canine stem cell-derived exosomes (cSC-Exos) in ALI.

Non-operative treatment in advanced atraumatic osteonecrosis of the humeral head in patients under 50 years old: an observational study.

The humeral head is the second most common anatomical site of osteonecrosis after the femoral head. Studies have reported satisfactory clinical outcomes after shoulder arthroplasty to treat osteonecrosis of the humeral head (ONHH). However, there are concerns regarding implant longevity in relatively young patients.

Medium-Sized Rotator Cuff Tears Repaired With Transosseous-Equivalent Technique Plus Bone Marrow Stimulation Yielded Similar Short-Term Outcomes Regardless of Whether Complete or Incomplete Footprint Coverage Was Achieved.

Purpose: To compare clinical outcomes and retear rates of medium-sized rotator cuff tears repaired with incomplete footprint coverage using the transosseous-equivalent technique versus those with complete footprint coverage plus bone marrow stimulation.

Methods: The retrospective study, conducted from March 2019 to December 2021, included consecutive patients with medium-sized (1-3 cm) posterosuperior rotator cuff tears repaired using the transosseous-equivalent technique and bone marrow stimulation, with a minimum follow-up of 2 years. Patients were divided into 2 groups based on the degree of footprint coverage achieved: group C (complete coverage) and group I (incomplete coverage).
