Background: This study was undertaken to investigate the growth rate and clinical outcome of patients with a small renal mass (SRM) after delayed surgery versus immediate surgery.
Methods: We reviewed the clinical records of 328 patients with SRM ≦ 4cm at diagnosis, who underwent delayed or immediate surgical intervention from January 2000 to December 2011. Radiographic evaluation using CT scan and MRI were performed at least every 6 months and the tumor size was determined at least twice in the delayed surgery group.
Results: A total of 292 RCC patients with pT1aN0M0 were identified; among them, 32 patients had been managed with delayed surgery intervention. No statistically significant difference was observed in overall survival rate (OSR) and cancer recurrence-free rate (CRFR). But cancer-specific survival rate (CSSR) was significantly lower in the delayed surgery group (p=0.0002).
Conclusions: The overall survival rate of delayed surgery was not inferior compared with that after immediate surgery. Delayed surgery intervention for SRMs is a treatment option in the current study.

Radiofrequency ablation combined with immunotherapy to treat hepatocellular carcinoma: a comprehensive review.

General Surgery, Cancer Center, Department of Hepatobiliary & Pancreatic Surgery and Minimally Invasive Surgery, Affiliated People's Hospital, Zhejiang Provincial People's Hospital, Hangzhou Medical College, Hangzhou, 310014, Zhejiang, China.
Background And Aim: Hepatocellular carcinoma (HCC) is a highly immunogenic tumor and the third leading cause of cancer-related deaths worldwide with an increasing incidence. Therefore, the combination of immunotherapy with other approaches, such as anti-angiogenic agents and local area therapy, has become a new strategy for HCC treatment.
Methods: We searched PubMed and Web of Science and extracted publications relating to the radiofrequency ablation (RFA) and immunotherapy.
Lobar lung transplantation, followed by partial sternal resection and bronchial stenosis, in a patient with scoliosis.

Scoliotic deformity represents a serious spinal disorder that influences the locomotive and cardiopulmonary systems. Some patients with severe scoliosis and end-stage lung disease are therefore denied lung transplantation. In patients with scoliosis considering lung transplantation, size match, straight back syndrome, delayed chest closure and bronchial stenosis are key issues clinicians should evaluate.

Background: Prone position has been diffusely applied in mechanically ventilated COVID-19 patients. Our aim is ascertaining the association between the physiologic response and the length of the first cycle of prone position and intensive care unit (ICU) mortality.
Methods: International registry including COVID-19 adult patients who underwent prone positioning.
Whole-body networks: a holistic approach for studying aging.

Department of Surgery, Immanuel Clinic Rüdersdorf, University Clinic of Brandenburg Medical School, Berlin, Germany.
Aging is a multi-organ disease, yet the traditional approach has been to study each organ in isolation. Such organ-specific studies have provided invaluable information regarding its pathomechanisms. However, an overall picture of the whole-body network (WBN) during aging is still incomplete.

Introduction: ST-elevation myocardial infarction (STEMI) is one of the most prevalent presentations in young patients. It is essential to emphasise that each minute of delay in providing medical care is negatively correlated to the patient's prognosis. The present study was carried out to evaluate the ischaemia-reperfusion times in patients ≤40 years of age versus individuals >40 years of age and their association with mortality and major adverse cardiac event (MACE) over the long term.
