Sonographic muscle mass assessment in patients after cardiac surgery

Cardiac surgery procedures are among the main treatments for people with cardiovascular disease, with physiotherapy playing a vital part. Respiratory complications are common and associated with prolonged Intensive Care Unit (ICU) and hospital stay, as well as increased mortality. Inspiratory muscle training has been found to be beneficial in improving respiratory muscle function in critically ill patients and patients with heart failure. The purpose of this review is to present the results of implementing inspiratory muscle training (IMT) programs in patients before and/or after cardiac surgery. The PubMed, Embase and Science Direct databases were searched from January 2012 to August 2023. In the present review, randomized controlled clinical trials (RCTs), clinical trials and quasi-experimental studies conducted in adult patients pre and/or post cardiac surgery were included. Fifteen studies were considered eligible for inclusion in the review. The results revealed that the IMT programs varied in intensity, repetitions, and duration in all included studies. Most studies implemented the IMT after the surgery. Statistical significance between groups was noted in Maximal Inspiratory Pressure and the 6-Minute Walk Distance Test. Preoperative and postoperative programs could improve inspiratory muscle strength, pulmonary function, and functional capacity as well as decrease the length of hospital stay in patients undergoing cardiac surgery. No clear evidence emerged favoring low or higher IMT intensities. The combination of IMT with other forms of exercise might be beneficial in patients undergoing cardiac surgery. However, further RCTs are required to provide confirming evidence.

Background: Aneurysm formation is a possible, but rare, complication of granulomatosis with polyangiitis, known as Wegener’s granulomatosis. Urgent diagnosis and therapy is very important because a ruptured aneurysm could be life threatening. Case presentation: We, therefore, present the case of a 63-year-old Greek man who was diagnosed with granulomatosis with polyangiitis and retroperitoneal hematoma due to ruptured aneurysm in renal artery and upper pancreaticoduodenal artery. His clinical course was complicated by acute renal failure and acute respiratory failure due to alveolar hemorrhage. Emergency coil embolization was performed. Postembolization recovery was uneventful; no bleeding occurred. The patient underwent mechanical ventilation and continuous veno-venous hemofiltration and received combined immunosuppression and supportive therapy, but eventually died 30 days after admission to hospital from severe septic shock and multiple organ failure. Conclusion: Endovascular treatment is the therapy of choice, especially for patients with ruptured aneurysms that are hemodynamically stable. Early diagnosis is very important, as urgent embolization and early initiation of immunosuppression therapy are the treatment of choice.

The data about the optimal duration of antibiotics and the usefulness of corticosteroids in the management of parapneumonic effusion and pleural infection are scarce. Two randomised controlled trials evaluating short antibiotic courses (ODAPE and SLIM) and another trial assessing the benefit from corticosteroid use (STOPPE) in this setting were recently published. The aim of this journal club is to present these trials and discuss their significance and limitations. ODAPE compared the efficacy and safety of a short (2 weeks)versusan extended (3 weeks) course of amoxicillin–clavulanate in community-acquired complicated parapneumonic effusions, while SLIM compared the efficacy and safety of short (14–21 days)versuslonger (28–42 days) antibiotic courses in patients with community- or hospital-acquired pleural infection. STOPPE assessed the benefit from dexamethasone use in patients with community-acquired pneumonia and concomitant pleural effusion. Both ODAPE and SLIM found that shorter antibiotic courses produce less adverse events while being equally efficacious to the longer courses in a subgroup of patients, such as those with pleural infection that is stabilised with only medical treatment and does not require surgery. In contrast, STOPPE found no benefit from the use of dexamethasone in unselected patients with pneumonia and pleural effusion. Due to the significant limitations of these trials, further studies are required to confirm these findings.Commentary on: Hassan M,et al.

Bronchoscopic drainage of a pyogenic lung abscess is an established therapeutic approach in selected patients in whom conventional antibiotic therapy fails. This intervention has also been undertaken in patients with abscess owing to underlying lung cancer and prior combined radiochemotherapy. However, this procedure has rarely been performed in cavitary lesions of advanced tumor origin before initiating any chemotherapy/radiotherapy scheme. Herein, we describe a case of a 68-year-old woman with lung adenocarcinoma stage IIIB, who underwent bronchoscopic drainage of necrotizing tumor lesion, thus improving her initial poor clinical condition and rendering other treatment modalities, such as radiotherapy, more effective and beneficial. Bronchoscopic drainage of a symptomatic cancerous lung abscess should be considered as an alternative and palliative treatment approach in patients with advanced inoperable non-small cell lung cancer.
