Abstract: Objective To evaluate the results of surgical treatment of tetralogy of Fallot in adults． Methods From July 2002 to August 2009，75 adult patients with tetralogy of Fallot received surgical treatment in Xijing Hospital, ForthMilitary Medical University．There were 35 males and 40 females, with age at l7 to 37 years (23.30±3.50 years), and eoperativehemoglobin at 143 to 231 g/L(172.00±31.00 g/L)．All these patients were diagnosed by.echocardiograph before operation. All the patients were received tetralogy of Fallot of corrective operation in the hypothermia cardiopulmonary bypass. A total of 46 patients had a transannular right ventricular outflow tract patch，and 29 patients had a non ansannular patch． Results Operation time was 157 to 276 min(221.32±41.34 min), cardiopulmonary bypass time was 68 to 163 min(91.71±28.35 min) and aorta intercepted time was 37 to 96 min（55.47±23.61 min）. There were 6 operative deaths with an operative mortality at 8.00％. The causes of death were low output syndrome(n=3)，acute renal failure(n=2)， and multiple organ failure(n=1)．Nine patients needed reoperation for postoperative bleeding(12.00％)．We followed up 69 patients from 3 to 56 months (26.31±7.40 months). There were 2 patients with trivial residual shunt. The cardiac function status were New York Heart Association(NYHA) Ⅰ to Ⅱ in the 69 patients．No late death occured． Conclusion The effectiveness of surgical treatment for adults with tetralogy of Fallot is satisfactory．
ObjectiveTo summarize the research progress of femoral neck system (FNS) in the treatment of femoral neck fracture in young and middle-aged patients. Methods The literature on FNS at home and abroad in recent years was extensively reviewed, and the results of mechanical and clinical studies on FNS were summarized based on clinical experience. Results FNS has good mechanical stability, which can reduce complications such as femoral neck shortening, internal fixation failure, and varus caused by mechanical instability. At present, FNS is mainly selected for comparison with cannulated compression screws and dynamic hip screws in clinical research. The results show that FNS has the advantages of minimally invasive, short operation time, less intraoperative fluoroscopy, earlier postoperative weight-bearing and fracture healing, and better hip function recovery. Conclusion As a new internal fixator, FNS has achieved satisfactory results in the current research. FNS has good mechanical advantages, which is beneficial to fracture healing and the recovery of hip joint function after operation. However, whether FNS can reduce the incidence of nonunion and osteonecrosis of the femoral head remains to be further clarified.
Objective To investigate the effects of femoral offset and mechanical axis of the lower extremity on hip after osteotomy for adult developmental dysplasia of the hip (DDH). Methods A clinical data of 62 adult patients with DDH (62 hips), who underwent periacetabular osteotomy combined with femoral osteotomy between January 2016 and May 2019 and met selective criteria, was retrospectively analyzed. There were 6 males and 56 females. The age ranged from 18 to 38 years, with an average of 24.4 years. Body mass index ranged from 15.8 to 31.8 kg/m2, with an average of 21.8 kg/m2. There were 44 cases of Hartofilakidis typeⅠ and 18 cases of typeⅡ. According to the modified Tönnis osteoarthritis staging, 46 cases were stage 0 and 16 cases were stageⅠ. There were 13 cases with pelvic anteversion, 40 cases with normal pelvis, and 9 cases with pelvic retroversion. Intraoperative blood loss, length of hospital stay, and complications were recorded. Postoperative hip function was evaluated by Harris score and International Hip Outcome Tool (iHOT) score. The femoral offset, collo-diaphyseal angle, hip-knee-ankle angle (HKA), knee valus angle, CE (Wiberg central-edge angle), anterior CE angle, and acetabular index angle were measured and the osteotomy healing was observed on X-ray films. Patients were grouped according to postoperative femoral offset (≥48 mm or <48 mm) and HKA [varus group (HKA<177°), normal group (HKA 177°-183°), and valgus group (HKA>183°)]. Harris score and iHOT score were compared between groups. Results Intraoperative blood loss ranged from 200 to 1 550 mL, with an average of 476 mL. The length of hospital stay ranged from 8 to 21 days, with an average of 13.3 days. All incisions healed by first intention. All patients were followed up 2.0-4.5 years, with an average of 2.8 years. At 1 year after operation, the Harris score and iHOT score of the hip joint significantly increased when compared with those before operation (P<0.05); there were significant differences in the femoral offset, collo-diaphyseal angle, HKA, knee valus angle, CE angle, anterior CE angle, and acetabular index angle between pre- and post-operation (P>0.05). According to the modified Tönnis osteoarthritis staging, 38 cases were stage 0 and 24 cases were stageⅠ; and there was no significant difference between pre- and post-operation (χ2=2.362, P=0.124). There were 11 cases with pelvic anteversion, 38 cases with normal pelvis, and 13 cases with pelvic retroversion, showing no significant difference when compared with that before operation (χ2=0.954, P=0.623). The pubic branch osteotomy did not heal in 9 cases, proximal femur osteotomy did not heal in 2 cases, and inferior pubic ramus stress fracture occurred in 5 cases. There were significant differences (P<0.05) in the Harris score and iHOT score between femoral offset≥48 mm group (n=10) and femoral offset<48 mm group (n=52). There was no significant difference (P>0.05) in Harris score and iHOT score between varus group (n=13), normal group (n=40), and valgus group (n=9). Conclusion Periacetabular osteotomy combined with femoral osteotomy can improve the femoral offset and mechanical axis of the lower extremity of patients with DDH, and improve the functional score of the hip. However, excessive increase of femoral offset during femoral osteotomy is not desirable, resulting in low postoperative functional score.
Objective To explore the effect of low-load resistance training on physical fitness in aged adults. Methods Select the aged adults who will go to the outpatient Department of Rehabilitation Medicine of Peking Union Medical College Hospital between June 1, 2020 and May 31, 2021. The aged adults were randomly divided into three groups by using the method of random number table: medium intensity aerobic training group (aerobic training group), standard-load resistance training group (standard-load group) and low-load resistance training group (low-load group). The basic information, exercise endurance (peak power, peak oxygen uptake), exercise cardiopulmonary function [peak heart rate, predicted peak heart rate, peak minute ventilation (VE), ventilatory equivalent for carbon dioxide at anaerobic threshold (EqCO2 during AT)], muscle strength, and muscle oxygen related indexes were collected blindly before the first exercise and after 12 weeks of training, respectively. To compare the differences of the indexes before and after training. Results A total of 90 patients were enrolled, 30 in each group. There was no significant difference in age, sex, height, weight and body mass index among the three groups (P>0.05). There was no significant difference in cardiopulmonary endurance, cardiopulmonary function, muscle strength, muscle oxygen related indexes between the groups before and after training (P>0.05). Except for the indexes related to cardiac function (peak heart rate, predicted peak heart rate) and resting muscle oxygen level (P>0.05), other indexes related to pulmonary function, cardiopulmonary endurance, muscle strength, and time of muscle oxygen falling to the valley in the three groups were statistically significant compared with those before training (P<0.05). Except for peak power, peak oxygen uptake and time of muscle oxygen falling to the valley (P>0.05), the difference of muscle strength before and after training in the three groups was statistically significant (P<0.05), including grip strength, chest push, sitting rowing, leg extension, hip abduction, body bending and horizontal push and push, and the low-load group was better than the aerobic training group (P<0.05), but the improvement of body bending and horizontal push and push in the standard-load group was better than the low-load group (P<0.05). Conclusions Low-load resistance training, standard-load resistance training and aerobic training have almost the same effect on improving the physical fitness of the elderly. Low-load resistance training is superior to medium intensity aerobic training in improving muscle strength, which is an effective method to improve the physical fitness of the aged adults.
ObjectiveTo explore the clinical and pathological characteristics of lung carcinoma in young adults, and improve the early diagnosis and treatment. MethodsWe retrospectively analyzed 129 patients with lung carcinoma aged from 18 to 35 years old who came to West China Hospital of Siduan University from January 1st 2008 to December 31st 2014.Also we collected 32 young adults with lung benign mass to make the comparison of the clinical and pathological characteristics with the patients. ResultsIn the 129 patients with lung carcinoma, there were 72 females and 57 males.Adenocarcinoma (88/129) was the most common type of pathology, while others included small cell carcinoma (18/129), squamous cell carcinoma (13/129), and other types of carcinoma (10/129).Among patients with lung carcinoma, 41(31.8%) complained of refractory dry cough and another 40(31.0%) presented coughing and expectoration.Twenty-nine patients (22.5%) were misdiagnosed in their first visits.In young adults with lung carcinoma, 55.8% were at the Ⅳ stage with metastasis at the first-time diagnosis.Comparing with patients with benign lung mass, patients with lung carcinoma presented significantly more dry cough (P=0.011), chest distress (P=0.007) and weight loss (P=0.007);while fever was found more patients with lung benign mass (P=0.040).The differences in cough, expectoration, and emptysis between the two groups were not significant (P > 0.05). ConclusionsLung carcinoma in young adults often has atypical clinical presentations.Therefore, it is more commonly misdiagnosed.
ObjectiveTo provide reference for the formulation of public health policies through exploring the disease burden of aortic aneurysm (AA) in Chinese young adults. MethodsWe analyzed sex-specific mortality rates and years of life lost (YLLs) among Chinese young adults with AA in Global Burden of Disease (GBD) from 1990 to 2019, and compared with global and young adult AA data stratified by sociodemographic index (SDI). Joinpoint was used to analyze the time trend of AA burden among young males and females in China. The attributable risk factors for AA burden in young adults and its characteristics were analyzed. ResultsAmong young adults (15-39 years old) in China, the total of AA deaths in 2019 was 657 (95%UI 549-791), with an increase of 16.90% compared with 1990. The mortality rate in 2019 was 0.13 per 100 000 (95%UI 0.11-0.16), with an increase of 30.00% compared with 1990. In 2019, a total of 36921 YLLs (95%UI 30 865-44 445) were produced by young adults in China, with an increase of 13.21% compared with 1990. The YLLs rate in 2019 was 7.42 per 100 000 (95%UI 6.20-8.93), with an increase of 24.92% compared with 1990. The male YLLs rate was 11.49 per 100 000 (95%UI 9.22-14.28), with an increase of 35.18%. The female YLLs rate was 3.11 per 100 000 (95%UI 2.36-3.98), with a decrease of 3.12%. Both the AA mortality rate and YLLs rate in male young adults were higher than those in female young adults, and the growth rate from 1990 to 2019 was significantly higher than that in females. ConclusionThe disease burden of AA among young adults in China increases significantly from 1990 to 2019, mainly among males. The time trend of male and female AA YLLs in Chinese young adults is obviously inconsistent. The AA YLLs of Chinese male young adults are positively correlated with economic development and the progress of medical technology, and are in the process of gradual increase. The AA YLLs of Chinese female young adults are much lower than the average level, which is closely related to the low smoking rate.
ObjectiveTo systematically evaluate the correlation between interpersonal stress and suicidal ideation. MethodsThe PubMed, EMbase, Cochrane Library, CBM, WanFang Data and CNKI databases were searched to collect studies on the correlation between interpersonal pressure and suicidal ideation from database inception to April 27, 2022. Two researchers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 14.0 software. ResultsA total of 42 studies including 3 cohort studies, and 39 cross-sectional studies, with a total sample size of 193 810 participants were included. Meta-analysis showed that the risk of suicidal ideation was higher in people who had experienced interpersonal pressure than in people who had not (OR=2.11, 95%CI 1.99 to 2.23, P<0.01). Subgroup analysis showed that people in the Americas who had experienced interpersonal pressure were more strongly associated with suicidal ideation than people in other regions of the studied area. Young adults in the study who had experienced interpersonal pressure were more strongly associated with suicidal ideation than other studied age groups; People who had experienced partner pressure were more strongly associated with suicidal ideation than those who had experienced other types of interpersonal pressure. ConclusionThis study shows that people who have experienced interpersonal pressure are at greater risk of suicidal ideation, and there are certain differences among study areas, subjects and types of interpersonal pressure. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo analyze and compare the disease burden, trends, and influencing factors of lung cancer in adolescents and young adults (AYAs) in China and globally from 1990 to 2021, providing a reference for the prevention and treatment of lung cancer in China. MethodsIndicators of lung cancer disease burden in different genders and age groups in 204 countries or regions from 1990 to 2021 were retrieved and standardized from GBD 2021 database. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of the standardized rates of lung cancer in AYAs in China and globally from 1990 to 2021; changes in incidence, mortality, and disability-adjusted life years (DALYs) rates due to population growth, aging, and epidemiological changes were analyzed; differences in lung cancer disease burden in AYAs in different socio-demographic index (SDI) regions were analyzed; and the influencing factors of lung cancer in AYAs in China and globally were explored. ResultsFrom 1990 to 2021, the age-standardized incidence rate (ASIR) (AAPC=−0.18%, P<0.001), age-standardized mortality rate (ASMR) (AAPC=−0.62%, P<0.001), and age-standardized DALYs rate (AAPC=−0.62%, P<0.001) of lung cancer in AYAs in China showed a downward trend, consistent with the global trend, but the decline in China was relatively small. During this period, the age-standardized rates of various indicators of lung cancer in males in China and globally were higher than those in females, and the burden of lung cancer in Chinese males was heavier. However, due to the significant downward trend in males, the gap in lung cancer burden between males and females was narrowing. At the same time, from 2013 to 2021, the ASIR [annual percent change (APC)=2.01%, P<0.001], ASMR (APC=1.46%, P<0.001), and standardized DALYs rate (APC=1.46%, P<0.001) in China showed an upward trend. From 1990 to 2021, among the main influencing factors for the incidence, mortality, and DALYs rates of lung cancer in Chinese AYAs, the contribution of aging was upward-pushing, while the increase in global indicators was mainly attributed to population growth. The global burden of lung cancer in AYAs was overly concentrated in high SDI regions. Although the gap in lung cancer burden between high SDI and low SDI regions was narrowing, it remained widespread. Globally, smoking, environmental PM2.5, insufficient fruit intake, second-hand smoke, and indoor air pollution were prominent risk factors. ConclusionFrom 1990 to 2021, the global and Chinese AYAs lung cancer incidence and mortality rates generally show a downward trend, but the female lung cancer burden relatively increases, especially in young women without a history of smoking. Continued efforts are needed to reduce the burden of lung cancer in AYAs, especially the specific risk for young women.
ObjectiveTo investigate the effectiveness of three-dimensional (3D) navigation template in the adult cubitus varus osteotomy.MethodsBetween April 2013 and September 2015, 17 patients with cubitus varus were admitted. There were 6 males and 11 females, aged from 19 to 38 years, with an average age of 26.9 years. There were 10 cases of left elbow joints and 7 cases of right elbow joints. The disease duration was 9-30 years (mean, 18 years). Based on the preoperative X-ray film, the humerus-elbow-wrist (HEW) angle was (−13.2 ±3.3)°, the anteversion angle was (−10.5±2.3)°. The preoperative range of motion (ROM) of flexion was (127.3±7.3)° and ROM of extension was (−10.0±2.5)°. Based on the CT 3D reconstruction, the osteotomy navigation template was designed and printed by 3D printing technique. The cubitus varus osteotomy was assisted by 3D navigation template. The postoperative HEW angle, anteversion angle, and ROMs of the elbow joints of both sides were measured. The elbow function was evaluated based on the Oppenheim elbow function score at 1 year after operation.ResultsAll cubitus varus osteotomies succeeded with the assist of 3D navigation template. All incisions healed by first intention. All patients were followed up 12-15 months (mean, 13 months). X-ray films showed that all osteotomies healed after 9-12 weeks (mean, 11 weeks). At 1 year after operation, the HEW angle was (9.7±1.9)°, the anteversion angle was (20.7±4.3)°, the ROM was (2.6±3.5)° in extension and (139.2±4.8)° in flexion of affected side. The HEW angle, anteversion angle, and ROMs significantly increased compared with preoperative values (P<0.05). And there was no significant difference between affected and normal elbow joints (P>0.05). The elbow functions were excellent in 13 cases and good in 4 cases based on the Oppenheim elbow function score at 1 year after operation. There was no complication such as the nerve injury or osteomyositis of elbow joint during follow-up. ConclusionThe 3D navigation template can provide a personalized and precise osteotomy treatment for adult cubitus varus deformity and obtain a satisfactory effectiveness.
ObjectiveTo investigate the current status of work readiness and its influencing factors among postoperative lung cancer patients returning to work. MethodsA retrospective study was conducted on young and middle-aged postoperative lung cancer patients who were treated at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to September 2023 and returned to their jobs. Data were collected through a general information questionnaire, readiness for return-to-work scale (RRTW), general self-efficacy scale (GSES), and simplified coping style questionnaire (SCSQ). Univariate and multivariate logistic regression analyses were used to explore the factors affecting the work adaptation of returning patients. ResultsA total of 219 patients were included, with 59 males and 160 females aged 18-60 years. Among the postoperative lung cancer patients returning to work, 73.1% were in the active maintenance stage of return-to-work readiness with a RRTW score of (17.59±1.48) points, and 26.9% were in the uncertain maintenance stage with a RRTW score of (16.22±1.50) points. Bivariate logistic regression analysis showed that patients aged≤30 years (OR=52.381), employees of enterprises and institutions (OR=7.682), agricultural, pastoral, fishery, forestry laborers (OR=15.665), and those with higher self-efficacy (OR=1.157) had higher return-to-work readiness, while patients with≥2 children (OR=0.055), positive coping (OR=0.022), and out-of-pocket expenses (OR=0.044) had lower return-to-work readiness. ConclusionThe return-to-work readiness of young and middle-aged postoperative lung cancer patients needs to be improved, and occupation, job nature, main coping styles, and general self-efficacy are associated with return-to-work readiness.
