To improve the current situation of multiple preoperative visits and evaluations for elderly patients and other patients with complex conditions, in December 2022, Peking Union Medical College Hospital established preoperative multidisciplinary evaluation clinic (shorted as joint clinic). The joint clinic established a multidisciplinary team, clarified service targets, and developed standardized clinic workflows to provide patients with a " one-stop" preoperative assessment(physical fitness assessment, nutritional assessment, and frailty assessment, etc.), nutritional optimization intervention, and prerehabilitation education and guidance services. This practice strengthened preoperative risk management, improved preoperative assessment efficiency, and ensured the safety of patients during the perioperative period. As of September 2023, the joint clinic had received a total of 128 patients, of which 86 underwent surgery after preoperative evaluation and prehabilitation optimization. The obesity rate, smoking rate, and number of frailty cases of these patients had decreased from 13.96%, 11.63%, and 18 at the time of visit to 9.30%, 4.65%, and 14 on the day before surgery, respectively. They had recovered well after surgery. This practice had improved the preoperative status of patients and created conditions for high-risk patients to undergo surgery smoothly, so as to provide references for other hospitals to carry out multidisciplinary collaborative preoperative evaluation works.

Objective:To investigate the surgical techniques and advantages of Ti-Robot-assisted surgery for pelvic fragility fractures in the elderly.Methods:A retrospective review was performed on geriatric patients presenting with pelvic fractures at the Orthopedics Department of Trauma, China-Japan Union Hospital of Jilin University from September 2019 to December 2022. Minimally invasive procedures were executed with the assistance of the Ti-Robot, and the therapeutic outcomes were appraised. The cohort comprised 24 patients aged ≥60 years, consisting of 6 men and 18 women, with a mean age of 66.1±4.9 years (range, 60-77 years). Fourteen patients sustained high-energy trauma, while 10 encountered low-energy trauma. Fracture classification utilized the FFP system proposed by Rommens and Hofmann. The cohort included 20 patients with FFP II fractures (5 males, 15 females; 4 of type IIa, 12 of type IIb, and 4 of type IIc) and 4 patients with FFP III fractures (1 male, 3 females; all type IIIa). The Matta standard assessment scale gauged fracture reduction, while the Gras classification, with Ti-Robot assistance, assessed screw positioning. Postoperative functionality was holistically assessed based on the Majeed quantitative evaluation system, focusing on pain intensity, sitting, standing, walking, and daily activities. The visual analogue scale (VAS) gauged pain levels in patients with type II fractures, pre and 72 hours post-surgery.Results:According to the Matta standard assessment scale, postoperative fracture reduction quality in 24 elderly patients showed 18 as excellent, 4 as good, and 2 as fair, yielding a 92% (22/24) combined excellent and good rate. Based on the Gras classification, 52 screws were rated as excellent and 7 as good, achieving a 100% positive rate. Utilizing Majeed's modified pelvic fracture evaluation system, postoperative functional recuperation revealed 19 patients as excellent and 5 as good. There were no reports of severe internal disease exacerbations, neurological manifestations, infections, or intraoperative extensive hemorrhaging, with all patients remaining stable. Fractures exhibited robust healing during follow-ups, averaging a recovery time of 3.5±0.7 months (range, 3-5 months). The VAS for 20 patients with FFP type II fractures decreased from 6.3±2.0 pre-surgery to 4.1±1.4 post-surgery ( t=6.14, P=0.003), signifying substantial pain mitigation. Conclusion:In the elderly with pelvic fragility fractures, particularly type II, securing with channel screws is viable. The Ti-Robot-assisted minimally invasive approach is advocated due to its potential to diminish surgical risks and expedite postoperative recuperation.

Objective    To share the experience of treating special cardiac malformations by applying minimally invasive techniques. Methods    Eight children with special cardiac malformations admitted to our hospital from July 2014 to September 2020 were recruited, including 3 males and 5 females, aged 0.8-1.2 (1.1±0.4) years, and weighted 7.8-11.5 (9.6±2.9) kg. There were 2 patients of huge muscular ventricular septal defect (VSD), 3 perimembranous cribriform VSD, 1 right coronary-right atrial fistula, 1 right coronary-right ventricular fistula, and 1 young, low-weight child with large aortopulmonary. All were treated with minimally invasive techniques using transesophageal echocardiography (TEE) as a guiding tool. All children received intraoperative TEE immediately to evaluate the curative effect of the surgery, and all went to outpatient clinic for reexamination of echocardiography, electrocardiogram and chest X-ray after discharge. Results    Eight children underwent minimally invasive surgery successfully without any incision infection, intracardiac infection, arrhythmia or pericardial effusion. None of the 8 children were lost to follow-up, and the results of all reexaminations were satisfactory. Conclusion    The application of minimally invasive techniques is a bold and innovative attempt for the treatment of a few special types of cardiac malformations. It has significant advantages in reducing trauma and medical costs in some suitable patients, and has certain clinical reference values.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective:To investigate the correlation between urinary 8-oxo-7, 8-dihydroguanosine(8-oxo-Gsn)and physical function in community-dwelling elderly people.Methods:A total of 210 community-dwelling elderly people aged 75 years and over were enrolled in this cross-sectional analysis.According to the scores of short physical performance battery(SPPB), subjects were divided into three groups: the high performance group(summary score 10-12), the intermediate performance group(summary score 7-9)and the low performance group(summary score 0-6). All participants received a comprehensive geriatric assessment.Urinary 8-oxo-dGsn, serum high-sensitivity C-reactive protein(hs-CRP)and white blood cell count were measured.The correlation between urinary 8-oxo-Gsn and physical function was analyzed by using Pearson correlation analysis and the ordered Logistic regression model.Results:The scores of activities of daily living(ADL), instrumental activities of daily living(IADL), grip strength and gait speed were lower in the low performance group than in the other two groups( H=47.002, 110.902, F=11.962, 235.952, all P<0.001). Levels of urinary 8-oxo-Gsn and serum hs-CRP were higher in the low performance group than in the other two groups( F=23.780 and 13.259, both P<0.001). There was no significant difference in levels of urinary 8-oxo-dGsn or white blood cell count between the three groups(both P>0.05). Urinary 8-oxo-Gsn was negatively correlated with gait speed, grip strength and SPPB score( r=-0.559, -0.302 and-0.450, all P<0.001)and was positively correlated with the time of five-times-sit-to-stand test( r=0.290, P<0.001). Adjusting for age, gender and Charlson comorbidity index, the ordered Logistic regression analysis showed that elevated levels of urinary 8-oxo-Gsn( OR=1.38, 95% CI: 1.06-1.77, P<0.05)and hs-CRP( OR=1.23, 95% CI: 1.04-1.48, P<0.05)decreased physical function. Conclusions:Urinary 8-oxo-Gsn is independently associated with the decline of physical function in community-dwelling elderly adults, suggesting that the oxidative stress level is increased in the elderly with poor physical function.

Objective To explore the association between frailty and muscle performances of hospitalized elder adults with coronary artery disease.Methods A total of 122 hospitalized patients aged 65-85 years old with coronary artery disease from Department of Geriatrics and Cardiology,Peking Union Medical College Hospital between December 2017 and March 2018 were enrolled in the study.A comprehensive geriatric assessment was performed to evaluate existing comorbidity and geriatric syndromes of the patients.Frailty was assessed using the Clinical Fraity Scale.The patients were classified as frail and non-frail,according to the scale.Muscle performances were assessed using grip strength,gait speed,etc.Whole body and appendicular skeletal muscle mass was detected with bioelectrical impedance analysis in patients with reduced grip strength or slowed gait speed.Appendicular skeletal muscle index (ASMI) was calculated.Results Among all subjects,28 were with frailty (23.0％) and 94 were without (77.0％).The frail patients were older [(76.7±5.4) years vs.(72.2±5.6)years],had higher Charlson comorbidity index [2.0(1.0,2.75)vs.1.0(0,2.0)],and higher proportion of malnutrition (14.29％ vs.1.06％),urinary incontinence (39.29％ vs.15.96％),using walking-aid (28.57％ vs.6.38％),and more kinds of taken drugs (8.1±3.0 vs.6.6±2.7),than the non-frail patients.Prealbumin levels [(207.8±60.0)mg/L vs.(234.3±45.4)mg/L] were lower,and highly sensitive C-reactive protein levels [(5.89±9.57)mg/L vs.(1.89±2.49)mg/L] were higher in the frail patients than in the non-frail patients (all P＜0.05).Compared with non-frail patients,the frail patients had poorer grip strength [(19.67±7)kg vs.(29.23±8.29)kg] and slower gait speed [(0.54±0.2)m/s vs.(0.91±0.22)m/s](all P＜0.001).Spearman rank correlation analyses showed that grip strength was positively correlated with the appendicular skeletal muscle mass(r =0.811),whole body skeletal muscle mass(r =0.74) and the ASMI (r =0.783),respectively.Conclusions The incidence of frailty among hospitalized older adults with coronary artery disease is high.Poor muscle performances were common in these patients.Assessment of frailty and muscle performances can help to evaluate the overall function of older adults with cardiovascular disease in a comprehensive way.
