IntroductionThe objective of this prospective study was to assess short- and long-term efficacy of exercise training (ET) as add-on to medical therapy in patients with connective tissue disease-associated pulmonary arterial hypertension (CTD-APAH).MethodsPatients with invasively confirmed CTD-APAH received ET in-hospital for 3 weeks and continued at home for 12 weeks. Efficacy parameters have been evaluated at baseline and after 15 weeks by blinded-observers. Survival rate has been evaluated in a follow-up period of 2.9 ± 1.9 years.ResultsTwenty-one consecutive patients were included and assessed at baseline, and after 3 weeks, 14 after 15 weeks. Patients significantly improved the mean distance walked in 6 minutes compared to baseline by 67 ± 52 meters after 3 weeks (p < 0.001) and by 71 ± 35 meters after 15 weeks (p = 0.003), scores of quality of life (p < 0.05), heart rate at rest, peak oxygen consumption, oxygen saturation and maximal workload. Systolic pulmonary artery pressure and diastolic systemic blood pressure improved significantly after 3 weeks of ET. The 1- and 2-year overall-survival rates were 100%, the 3-year survival 73%. In one patient lung transplantation was performed 6 months after ET.ConclusionET as add-on to medical therapy is highly effective in patients with CTD-APAH to improve work capacity, quality of life and further prognostic relevant parameters and possibly improves the 1-, 2- and 3-year survival rate. Further randomized controlled studies are needed to confirm these results.Trial registrationClinicalTrials.gov: NCT00491309.

Visual recovery after successful surgery for the macula-off rhegmatogenous retinal detachment continues to be an important topic for ophthalmologists. Recent studies have shown that despite the intuitive notion regarding outcomes in macula-off detachment, there is no improvement in final visual acuity despite more expedient repair within the first week. Macula-off detachments can therefore be treated with less urgency and can wait for the next scheduled available operating room time. Surgeons involved in retinal detachment surgery should be aware that visual function based on acuity testing may continue to improve in the long term, most notably in those with the following patient characteristics: younger age, no or mild myopia (less than -5.00 D), and shorter duration of macular detachment (30 days or less).
