Background: Fractures of the lateral aspect of the clavicle with complete displacement have a high nonunion rate and are associated with poor functional outcomes following nonoperative treatment. Various techniques are available to treat these fractures, but preliminary studies of open reduction and tunneled suspensory device (ORTSD) fixation have shown good early functional outcomes with a low rate of complications; our goal was to assess the functional outcomes and complications in the medium term in a larger series of patients treated using this technique.
Methods: Sixty-seven patients with displaced lateral-end clavicular fractures were treated with ORTSD fixation. Outcome was assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Oxford shoulder score at 6 weeks and 3, 6, and 12 months postoperatively. Fifty-five of 64 surviving patients were subsequently contacted at a mean of 69 months (range, 27 to 120 months) postoperatively to complete DASH and Oxford shoulder scores, to evaluate their overall level of satisfaction, and to document any further complications.
Results: At 1 year postoperatively, the mean Oxford shoulder score was 46.4 points and the mean DASH score was 2.4 points in 59 of the 67 patients assessed at this time interval. At the later follow-up (mean, 69 months), the mean Oxford shoulder score was 46.5 points and the mean DASH score was 2.2 points in the 55 surviving patients who were able to be contacted. There were no significant differences between the 1-year functional scores and those at the latest follow-up. Two patients developed a symptomatic nonunion requiring reoperation, and 2 patients developed an asymptomatic fibrous union not requiring a surgical procedure. The 5-year survival when considering only obligatory revision for implant-related complications was 97.0%.
Conclusions: ORTSD fixation for isolated displaced lateral-end clavicular fractures in medically fit patients is associated with good functional outcomes and a low rate of complications in the medium term. Routine implant removal was not necessary.

Objective: To determine the impact of prolonged storage of donor lungs at 10°C of up to 24h on outcome after lung transplantation.
Background: An increasing body of evidence suggests 10°C as the optimal storage temperature for donor lungs. A recent study showed that cold ischemic times can be safely expanded to >12h when lungs are stored at 10°C.

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression.

Declines in lysosomal acidification and function with aging are observed in organisms ranging from yeast to humans. V-ATPases play a central role in organelle acidification, and V-ATPase activity is regulated by reversible disassembly in many different settings. Using the yeast Saccharomyces cerevisiae as a replicative aging model, we demonstrate that V-ATPases disassemble into their V and V subcomplexes in aging cells, with release of V subunit C (Vma5) from the lysosome-like vacuole into the cytosol.

Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Purpose: Shoulder arthroscopic repair of rotator cuff tears with simultaneous treatment of lesions of the long head of the biceps tendon has become increasingly accepted. However, the clinical outcomes between tenotomy and tenodesis remain unclear. This study aimed to compare the efficacy of tenotomy and tenodesis combined with rotator cuff repair in elderly patients with medium-to-massive rotator cuff tears.
