Sternal nonunion is an uncommon complication after a sternal wound and some cases have been reported as a complication of open heart surgery. A 28-year-old male suffered from persistent sternal pain. Six years ago, open heart surgery was performed through a partial sternotomy with transverse sternotomy. The sternal nonunion was repaired using 3 sternal wires and 1 absorbable sternal pin. Three years later, the patient experienced recurrence of persistent sternal pain with clicking, because all of the sternal wires had ruptured and the sternal healing was incomplete. The patient was treated with adequate debridement and a technique using metal plates and autogenous bone grafts, which provided excellent pain relief. A transverse sternotomy potentially exposes the patient to the risk of sternal nonunion, which should be treated using autogenous bone grafting.

Remote monitoring of patients with COPD disease using a tablet system: a randomised crossover study of quality-of-life measurements.
ERJ Open Res
January 2025
Department of Respiratory Medicine and Allergology, COPD Center, Sahlgrenska University Hospital and Department of Internal Medicine and Clinical Nutrition, Institute of Medicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
Background: Remote patient monitoring (RPM) has been evaluated in COPD, but with varying results. We aimed to evaluate whether a tablet system that monitors disease-related parameters in patients with COPD could influence physical and mental health-related quality of life, compared with usual care (UC).
Methods: 70 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D COPD (61% women, aged 71±8 years, forced expiratory volume in 1 s % predicted 41±13%, COPD Assessment Test (CAT) 19±7 points) were recruited at the COPD centre in Gothenburg, Sweden, and randomised to a tablet-based RPM system or UC for a 26-week period, after which they crossed over to the alternative management for another 26 weeks.
Cost-effectiveness of follow-up algorithms for chronic thromboembolic pulmonary hypertension in pulmonary embolism survivors.
ERJ Open Res
January 2025
Department of Thrombosis and Hemostasis, Leiden University Medical Center, Leiden, The Netherlands.
Introduction: Achieving an early diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) in pulmonary embolism (PE) survivors results in better quality of life and survival. Importantly, dedicated follow-up strategies to achieve an earlier CTEPH diagnosis involve costs that were not explicitly incorporated in the models assessing their cost-effectiveness. We performed an economic evaluation of 11 distinct PE follow-up algorithms to determine which should be preferred.

Center for Pulmonary Vascular Biology and Medicine, Pittsburgh Heart, Lung and Blood Vascular Medicine Institute, Division of Cardiology, Department of Medicine, University of Pittsburgh School of Medicine and UPMC, Pittsburgh, PA, USA.
Background: Pulmonary arterial hypertension (PAH) is a deadly disease without effective non-invasive diagnostic and prognostic testing. It remains unclear whether vasodilators reverse inflammatory activation, a part of PAH pathogenesis. Single-cell profiling of inflammatory cells in blood could clarify these PAH mechanisms.

Division of Pulmonary and Critical Care Medicine, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA.
Background: In a phase 1b/2a clinical trial of efzofitimod in patients with corticosteroid-requiring pulmonary sarcoidosis, treatment resulted in dose-dependent improvement in key end-points. We undertook a analysis pooling dose arms that achieved therapeutic concentrations of efzofitimod (Therapeutic group) those that did not (Subtherapeutic group).
Methods: Peripheral blood mononuclear cells incubated with tuberculin-coated beads were exposed to varying concentrations of efzofitimod in an assay to determine concentrations that inhibited granuloma formation.
The impact of highly effective modulator therapy on sinusitis and dysosmia in young children with cystic fibrosis: a prospective study protocol.
ERJ Open Res
January 2025
Department of Otolaryngology-Head and Neck Surgery, University of California, Los Angeles, Los Angeles, CA, USA.
Background: Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are prevalent disease complications in people with cystic fibrosis. These understudied comorbidities significantly impact quality of life. The impact of highly effective modulator therapy (HEMT) in young children with cystic fibrosis (YCwCF) on these disease complications is unknown.
