Psoas attenuation is associated with early postoperative complications in geriatric patients undergoing multilevel lumbar fusion surgery for degenerative lumbar spinal stenosis.

BACKGROUND: Morphometric analysis of the psoas major muscle has shown utility in predicting postoperative morbidity in various surgical fields, but its usefulness in predicting complications in elderly patients undergoing multilevel lumbar fusion surgery has not been studied. The study aimed to investigate if psoas major parameters are independent risk factors of early postoperative complication among elderly patients. METHODS: Patients who underwent multilevel lumbar fusion for degenerative lumbar spinal stenosis (DLSS) were included. The psoas major was measured at the lumbar 3/4 intervertebral disc level in three ways on computed tomography image: psoas muscle mass index, mean muscle attenuation, and morphologic change of the psoas major. Early complications were graded using the Clavien-Dindo classification system and the Comprehensive complication index (CCI). A CCI ≥ 26.2 indicated severe complications. Logistic regression was performed to identify independent risk factors. RESULTS: This retrospective study reviewed 108 patients (mean age 70.9 years, female to male ratio 1.8:1). Complications were observed in 72.2% of patients, with allogeneic blood transfusion being the most frequent (66.7%), followed by wound infection, acute heart failure (2.8% each). Severe complications occurred in 13.9% of patients. After multivariable regression analysis, those in the lowest psoas muscle attenuation tertile had higher odds of experiencing early postoperative complications (OR: 3.327, 95% CI 1.134-9.763, p = 0.029) and severe complications (OR: 6.964, 95% CI 1.928-25.160, p = 0.003). CONCLUSION: The psoas muscle attenuation can be used as a predictor of early postoperative complications in elderly patients undergoing multilevel lumbar fusion surgery for DLSS.

[Clinical treatment and prognosis of adrenocortical carcinoma with venous tumor thrombus].

OBJECTIVE: To analyze the clinicopathological features, prognostic value and surgical treatment experience in patients with adrenocortical carcinoma with venous tumor thrombus. METHODS: We collected relevant data of the patients with adrenocortical carcinoma who had undergone surgery in Peking University Third Hospital from 2018 to 2023. The patients were divided into venous tumor thrombus group and non-tumor thrombus group. The Wilcoxon rank sum test was used to compare the quantitative variables. The chi-squared test and Fisher's exact test were used to compare the categorical variables. The Kaplan-Meier method was used to estimate the survival rate. RESULTS: A total of 27 patients with adrenocortical carcinoma were included, of whom 11 cases (40.7%) had venous tumor thrombus. In the patients with venous tumor thrombus, 8 patients were female and 3 were male. The median age was 49 (36, 58) years. The median body mass index was 26.0 (24.1, 30.4) kg/m2. Seven patients presented with symptoms at their initial visit. Six patients had a history of hypertension. Elevated levels of cortisol were observed in 2 cases. Three tumors were found on the left side, while 8 were found on the right side. Median tumor diameter was 9.4 (6.5, 12.5) cm. On the left, there was a case of tumor thrombus limited to the central vein of the left adrenal gland without invasion into the left renal vein, and two cases of tumor thrombus growth extending into the inferior vena cava below the liver. One case of tumor thrombus on the right adrenal central vein did not invade the inferior vena cava. Four cases of tumor thrombus invaded the inferior vena cava below the liver and three cases extended to the posterior of the liver. Ten patients were in European Network for the Study of Adrenal Tumors (ENSAT) stage Ⅲ and one was in ENSAT stage Ⅳ. Open surgery was performed in 6 cases, laparoscopic surgery alone in 4 cases and robot-assisted laparoscopic surgery in 1 case. Two patients underwent ipsilateral kidney resection. Median operative time was 332 (261, 440) min. Median intraoperative bleeding was 900 (700, 2 200) mL. Median hospital stay was 9 (5, 10) days. Median survival time for the patients with tumor thrombus was 24.0 months and median time to recurrence was 7.0 months. The median survival and recurrence time of 16 patients without tumor thrombus were not reached. The patients with tumor thrombus had worse 3-year overall survival (OS) rate (40.9% vs. 71.4%; Log-rank, P=0.038) and 2-year recurrence-free survival (RFS) (9.1% vs.53.7%; Log-rank, P=0.015) rates compared with the patients with non-tumor thrombus. CONCLUSION: Patients with adrenocortical carcinoma with venous tumor thrombus have poor prognosis. Different adrenal tumor resections and venous tumor thrombus removal procedures based on different tumor thrombus locations are safe and effective in treating this disease.

Effects of frequent assessments on the severity of suicidal thoughts: an ecological momentary assessment study.

Objective: In recent years, there has been a significant increase in research using ecological momentary assessment (EMA) to explore suicidal thoughts and behaviors (STBs). Meanwhile, concerns have been raised regarding the potential impacts of frequent and intense STBs assessments on the study participants. Methods: From November 2021 to June 2023, a total of 83 adolescent and young adult outpatients (Mage = 21.0, SDage = 6.3, 71.1% female), who were diagnosed with mood disorders, were recruited from three psychiatric clinics in China. Smartphone-based EMA was used to measure suicidal thoughts three times per day at randomly selected times. We examined the change of suicidal thoughts in each measurement and within 1 day to evaluate potential adverse effects using Bayesian multilevel models. Results: The 3,105 effective surveys were nested in 83 participants (median follow-up days: 14 days). The results of two-level models indicated that suicidal thoughts decreased during the monitoring period. However, this effect varied among different individuals in the two-level model. Conclusion: Our findings did not support the notion that repeated assessment of suicidal thoughts is iatrogenic, but future research should continue to investigate the impact of frequent assessment on suicidal thoughts, taking into account individual differences and utilizing larger sample sizes.

Hidden Charge Order and Multiple Electronic Instabilities in EuTe4.

The rare-earth telluride compound EuTe4 exhibits a charge density wave (CDW) and an unconventional thermal hysteresis transition. Herein, we report a comprehensive study of the CDW states in EuTe4 by using low-temperature scanning tunneling microscopy. Two types of charge orders are observed at 4 K, including a newly discovered spindle-shaped pattern and a typical stripe-like pattern. As an exotic charge order, the spindle-shaped CDW is off-axis and barely visible at 77 K, indicating that it is a hidden order developed at low temperature. Based on our first-principles calculations, we reveal the origins of the observed electronic instabilities. The spindle-shaped charge order stems from a subsequent transition based on the stripe-like CDW phase. Our work demonstrates that the competition and cooperation between multiple charge orders can generate exotic quantum phases.

Prevalence and correlates of mental health problems among different occupations of medical workers during COVID-19 outbreak in China.

Background: Health workers involved in the fight to prevent the COVID-19 outbreak were exposed to hazards. Detailed information on mental health problems in different medical occupations is crucial. To examined the prevalence of mental health issues in three medical occupations as well as the relationships between mental health problems and correlates in each occupation. Methods: This study utilizing the Questionnaire Star program was conducted among medical workers working at medical institutions in China from February 17 to 24, 2020. The Self-Reporting Questionnaire (SRQ-20), the Zung Self-rating Anxiety Scale (SAS), and the Zung Self-rating Depression Scale (SDS) were used to assess mental health problems. Results: The prevalence of any mental health problems in the three occupations was 43.6, 34.6, and 32.9% for nurses, paramedical workers (PMWs), and doctors, respectively. Three occupations shared some correlates, such as being overworked, not having enough time to rest, support from colleagues, and previous mental health status. There were specific factors for each occupation. For doctors, age, educational level, living status, support from family, and previous physical status were related factors in mental health problems. Working in a designated hospital for treating COVID-19, having COVID-19 event exposures, and receiving support from family were associated with the mental health problems of the nurses. PMWs' mental health problems was linked to educational level and care from supervisors or heads of department. Conclusion: Different medical occupations have distinct impacts on mental health issues. Policy makers and mental health professionals working to prepare for potential disease outbreaks should be aware of multiple factors in different occupations.

Predictors of achieving minimal clinically important difference in functional status for elderly patients with degenerative lumbar spinal stenosis undergoing lumbar decompression and fusion surgery.

OBJECTIVE: To identify the predictors for the achievement of minimal clinically important difference (MCID) in functional status among elderly patients with degenerative lumbar spinal stenosis (DLSS) undergoing lumbar decompression and fusion surgery. METHODS: Patients who underwent lumbar surgery for DLSS and had a minimum of 1-year follow-up were included. The MCID achievement threshold for the Oswestry Disability Index (ODI) was set at 12.8. General patient information and the morphology of lumbar paraspinal muscles were evaluated using comparative analysis to identify influencing factors. Multiple regression models were employed to identify predictors associated with MCID achievement. A receiver operating characteristic (ROC) curve analysis was conducted to determine the optimal cut-off values for predicting functional recovery. RESULTS: A total of 126 patients (46 males, 80 females; mean age 73.0 ± 5.9 years) were included. The overall rate of MCID achievement was 74.6%. Patients who achieved MCID had significantly higher psoas major muscle attenuation (43.55 vs. 39.23, p < 0.001) and preoperative ODI (51.5 vs. 41.6, p < 0.001). Logistic regression showed that elevated psoas major muscle attenuation (p = 0.001) and high preoperative ODI scores (p = 0.001) were independent MCID predictors. The optimal cut-off values for predicting MCID achievement were found to be 40.46 Hounsfield Units for psoas major muscle attenuation and 48.14% for preoperative ODI. CONCLUSION: Preoperative psoas major muscle attenuation and preoperative ODI were reliable predictors of achieving MCID in geriatric patients undergoing lumbar decompression and fusion surgery. These findings offer valuable insights for predicting surgical outcomes and guiding clinical decision-making in elderly patients.

Psoas muscle index and psoas muscle density are associated with functional status in patients with degenerative lumbar spinal stenosis.

BACKGROUND: The factors affecting lumbar spinal function in patients with degenerative lumbar spinal stenosis (DLSS) are still unclear. OBJECTIVE: This study explored psoas major muscle morphology in patients with DLSS and its association with their functional status. METHODS: A retrospective study was conducted on 288 patients with DLSS and 260 control subjects. Psoas major muscle evaluation included three morphometric parameters at the L3/4 disc level: psoas major index (PMI), muscle attenuation, and psoas major morphological changes (MPM). The association between psoas major morphology and functional status was assessed using the Oswestry disability index (ODI). RESULTS: Both female and male patients with DLSS had a higher PMI and lower muscle attenuation. PMI and muscle attenuation were inversely correlated with age in the DLSS group. After multivariable analyses, the PMI and psoas major muscle attenuation were positively correlated with patients' functional status. CONCLUSION: The PMI and muscle attenuation were positively correlated with functional status in patients with DLSS. These findings have important implications for physiotherapy programs of postoperative rehabilitation and conservative management of DLSS.

Associations of adverse childhood experiences with common psychiatric disorder in later life: results from the China mental health survey.

BACKGROUND: Associations between adverse childhood experiences (ACEs) and common psychiatric disorders among older Chinese individuals have not been well reported. The objectives of this study are to examine the prevalence of ACEs and the associations of ACEs with common psychiatric disorders among older adults in China. METHODS: The study used data from the China Mental Health Survey (CMHS), a nationally representative epidemiological survey, which used computer-assisted personal interviewing (CAPI), logistic regression models were used to examine community-based adult psychiatric disorders and associated risk factors. Finally, 2,317 individuals aged 60 years or over were included in the CMHS. The national prevalence of ACEs in older adults were estimated and logistic regression were used to analyse the association between ACEs and past-year psychiatric disorders. RESULTS: Prevalence of ACEs among older adults in China was 18.1%. The three most common types of ACEs were neglect (11.6%), domestic violence (9.2%), and parental loss (9.1%). This study proved the association between ACEs and common past-year psychiatric disorders in older adults. ACEs increased the risk of past-year psychiatric disorders in older adults. After adjustment for age, sex, marital status, employment status, education, rural or urban residence, region, and physical diseases, the association between ACEs and past-year psychiatric disorders were still significant. CONCLUSIONS: ACEs are linked to an increased risk for past-year psychiatric disorders in older adults. ACEs may have long-term effects on older adults' mental well-being. Preventing ACEs may help reduce possible adverse health outcomes in later life.

Knockdown of KIF15 suppresses proliferation of prostate cancer cells and induces apoptosis through PI3K/Akt signaling pathway.

Prostate cancer is one of the most common malignancies in men, which has been considered a public health threat. KIF15 is a kind of driver protein, and its abnormal expression is closely related to the occurrence and development of malignant tumors. The purpose of the study was to explore the significance and role of KIF15 in prostate cancer and to show some potential value for prostate cancer. Immunohistochemistry analysis showed that KIF15 was highly expressed in prostate cancer tissues, which was also positively correlated with T Infiltrate. The loss-of-function and gain-of-function assays based on prostate cancer cells indicated that the change in KIF15 expression could significantly affect cell proliferation, tumorigenesis, migration, and cell apoptosis. The inhibition of prostate cancer development by KIF15 knockdown was also assured in vivo. The Human Apoptosis Antibody Array showed that CD40L, cytoC, DR6, and p21 were up-regulated upon KIF15 knockdown, while IGF-I and Survivin were down-regulated. Moreover, the involvement of the PI3K/Akt pathway in the KIF15-mediated regulation of prostate cancer was preliminarily proved. In summary, KIF15 was identified to play an important role in the development or biological progress of prostate cancer and is considered to possess the potential to be used as a therapeutic target.

Management strategy for urologic morbidity in surgery of placenta accreta spectrum: stents or catheters?

OBJECTIVE: Surgery for placenta accreta spectrum disorders is known to be associated with urologic morbidity. Although previous studies have shown preoperative ureteral stent placement might be useful for preventing the urologic morbidity, the patient's discomfort caused by it should not be ignored. Whether there is an alternative management strategy remains unknown. This study was to evaluate the effectiveness of ureteral stents and catheters in preventing urologic injury in patients with placenta accreta spectrum undergoing surgery. METHODS: We conducted a retrospective cohort study. All cases with diagnosed placenta accreta spectrum who underwent surgery at Peking University Third Hospital between January 2018 and December 2020 were collected and reviewed. They were divided into two groups according to the different management strategies for preoperative placement of ureteral catheters or stents. The primary outcome was urologic injury, which was defined as the presence of ureteral or bladder injury during and after surgery. Secondary outcomes included urologic complications within the first three months after surgery. The median (interquartile range) or proportions were reported for variables. The Man Whitney U test, chi-square test and multivariate logistic regression were used for analysis. RESULTS: Ultimately, 99 patients were included in this study. Ureteral catheters were placed in 52 patients and ureteral stents were placed in 47 patients. Placenta accreta, placenta increta, and placenta percreta were diagnosed in three, 19, and 77 women, respectively. The hysterectomy rate was 52.53%. Overall, urologic injuries occurred in three patients (3.03%), including one case of combined bladder and ureteral injury (1.01%) and two cases of bladder injuries (2.02%). Only one ureteral injury occurred in a patient with a ureteral stent, which was recognized postoperatively (p = .475). All bladder injuries were vesical rupture which were recognized and repaired intraoperatively; one patient in the catheter group and two patients in the stent group (p = .929). After adjusting for confounding variables, multinomial regression analysis revealed no significant differences between the two groups in the incidence of bladder injuries(aOR: 0.695, 95% CI: 0.035-13.794, p = .811). A lower risk of urinary irritation (aOR: 0.186, 95% CI: 0.057-0.605, p = .005), hematuria (aOR: 0.011, 95% CI: 0.001-0.136, p < .001), and lower back pain (aOR: 0.075, 95% CI: 0.022-0.261, p < .001) was found in patients with ureteral catheters than in those with ureteral stents. CONCLUSION: The ureteral stents didn't confer a protective benefit in the surgical management for placenta accreta spectrum compare with catheters; however, they did result in a higher incidence of postoperative urologic complications. Ureteral temporal catheters may be an alternative strategy for placenta accreta spectrum cases suspected with urinary tract involved prenatally. Moreover, clearly and explicitly reporting "double J stent" or "temporal catheter" is necessary for future researches.

Fe-Intercalation Dominated Ferromagnetism of van der Waals Fe3 GeTe2.

Fe3 GeTe2 have proven to be of greatly intrigue. However, the underlying mechanism behind the varying Curie temperature (Tc ) values remains a puzzle. This study explores the atomic structure of Fe3 GeTe2 crystals exhibiting Tc values of 160, 210, and 230 K. The elemental mapping reveals a Fe-intercalation on the interstitial sites within the van der Waals gap of the high-Tc (210 and 230 K) samples, which are observed to have an exchange bias effect by electrical transport measurements, while Fe intercalation or the bias effect is absent in the low-Tc (160 K) samples. First-principles calculations further suggest that the Fe-intercalation layer may be responsible for the local antiferromagnetic coupling that gives rise to the exchange bias effect, and that the interlayer exchange paths greatly contribute to the enhancement of Tc . This discovery of the Fe-intercalation layer elucidates the mechanism behind the hidden antiferromagnetic ordering that underlies the enhancement of Tc in Fe3 GeTe2 .

Gleason Score-related MT1L as biomarker for prognosis in prostate adenocarcinoma and contribute to tumor progression in vitro.

BACKGROUND: The Gleason Score is well correlated with biological behavior and prognosis in prostate adenocarcinoma (PRAD). This study was derived to determine the clinical significance and function of Gleason-Score-related genes in PRAD. METHODS: RNA-sequencing profiles and clinical data were extracted from the The Cancer Genome Atlas PRAD database. The Gleason-Score-related genes were screened out by the Jonckheere-Terpstra rank-based test. The "limma" R package was performed for differentially expressed genes. Next, a Kaplan-Meier survival analysis was performed. Correlation MT1L expression levels with tumor stage, non-tumor tissue stage, radiation therapy, and residual tumor were analyzed. Further, MT1L expression was detected in PRAD cell lines by reverse transcription-quantitative polymerase chain reaction assay. Overexpression of MT1L was constructed and used for cell count kit-8, flow cytometric assay, transwell assay, and wound-healing assay. RESULTS: Survival analysis showed 15 Gleason-Score-related genes as prognostic biomarkers in PRAD. The high-frequency deletion of MT1L was verified in PRAD. Furthermore, MT1L expression was decreased in PRAD cell lines than RWPE-1 cells, and overexpression of MT1L repressed cell proliferation and migration, and induced apoptosis in PC-3 cells. CONCLUSION: Gleason-Score-related MT1L may serve as a biomarker of poor prognostic biomarker in PRAD. In addition, MT1L plays a tumor suppressor in PRAD progression, which is beneficial for PRAD diagnosis and treatment research.

Chinese version of Dominic Interactive - A self-report video game for assessing mental health in young children.

Objectives: Assess the validity of the Chinese version of the Dominic Interactive (DI), a 91-item, video-based diagnostic screening instrument for children that assesses four internalized disorders (phobias, separation anxiety disorder, generalized anxiety disorder, and major depressive disorder) and three externalized disorders (attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder). Methods: (1) Compare DI-generated "probable" or "possible" diagnoses to diagnoses based on the Development and Well-Being Assessment (DAWBA) instrument in 113 psychiatric outpatients and 20 community controls. (2) Administer DI to 1,479 children from elementary schools in Tianjin. Results: In the validation sample, DI with DAWBA concordance was much greater for internalized disorders (mean Kappa = 0.56) than for externalized disorders (mean kappa = 0.11). The positive predictive value of DI diagnoses ranged from 0.96 (generalized anxiety disorder) to 25% (oppositional defiant disorder) and negative from 0.81 to 0.96. Using "probable" cuts provides better results. In the survey, prevalence of probable DI disorders ranged from 1.0% (conduct disorder) to 13.1% (phobias). Internal consistency of all DI items was excellent (Cronbach alpha = 0.93) and that of the seven subscales ranged from 0.64 (phobias) to 0.87 (major depressive disorder). In multilevel SEM analyses, SRMR (Standardized root mean square residual) or each of the seven diagnoses was below 0.08 and each coefficient of determination was below 0.60. Conclusion: The Chinese DI is a convenient method of screening common mental disorders in Chinese children mainly for internalized disorders, which are the most prevalent diagnoses in that population. However its high negative predictive values for externalized could be used for screening.

ATAD2 promotes glycolysis and tumor progression in clear cell renal cell carcinoma by regulating the transcriptional activity of c-Myc.

Clear cell renal cell carcinoma (ccRCC) is a common malignant tumor of the urogenital tract. Given that ccRCC is often resistant to radiotherapy and traditional chemotherapy, the clinical treatment of patients with ccRCC remains a challenge. The present study found that ATAD2 was significantly upregulated in ccRCC tissues. In vitro and in vivo experiments showed that the inhibition of ATAD2 expression mitigated the aggressive phenotype of ccRCC. ATAD2 was also associated with glycolysis in ccRCC. Interestingly, we found that ATAD2 could physically interact with c-Myc and promote the expression of its downstream target gene, thereby enhancing the Warburg effect of ccRCC. Overall, our study emphasizes the role of ATAD2 in ccRCC. The targeted expression or functional regulation of ATAD2 could be a promising method to reduce the proliferation and progression of ccRCC.

Suicidal ideation and its relationship with mental health reported by different informants among children aged 6-12.

BACKGROUND: Suicidal ideation in children has received less attention than in adolescents. This study aimed to explore the self-reported prevalence of suicidal ideation among children aged 6-12 and to identify the relationship between self-reported suicidal ideation and children's mental health reported by different informants in Chinese setting. METHOD: The study sample was 1479 children aged 6-12 from three elementary schools in Tianjin. Children completed the Dominic Interactive to report their mental health and suicidal ideation. Parents and teachers completed the Socio-Demographic Questionnaire and the Strengths and Difficulties Questionnaire (SDQ). RESULTS: The prevalence of suicidal thoughts and death thoughts was 18.05 % and 16.90 %, respectively. Parent reported emotional symptoms, ADHD, and externalized problems were associated with death thoughts, and ADHD was associated with suicidal thoughts. For teacher's reports, emotional symptoms, and impact were associated with death thoughts, and ADHD, peer problems, internalized problems, and internalized and externalized comorbidity were associated with suicidal thoughts. All of the children's self-reported mental health problems were associated with suicidal thoughts and death thoughts. LIMITATIONS: Causality cannot be inferred in a cross-sectional study. CONCLUSION: Suicidal ideation is not uncommon in Chinese children. The relationships between mental health problems and suicidal ideation varied in different informants. Suicide prevention in young children should be enhanced, and screening for suicidal ideation is recommended at the onset of different informants who reported specific mental health problems.

Retroperitoneal bronchogenic cyst resembling an adrenal tumor in adult: Three case reports and literature review.

Bronchogenic cyst is a rare congenital malformation of the tracheobronchial bud originating from the primitive foregut, especially in the retroperitoneal region. Retroperitoneal bronchogenic cysts in adults are difficult to make an accurate diagnosis preoperatively. Case presentation: We present three cases of retroperitoneal bronchogenic cysts resembling adrenal tumors in adults. Three cases were asymptomatic, and all were located on the left side. There was no significant enhancement of the cyst walls on contrast-enhanced computed tomography. Two cases presented with typical multilocular sacs and scattered calcification on radiology, whereas the other one showed unilocular sacs, without calcification, and elevation of serum carbohydrate antigen (CA) 19-9 and CA 24-2. Three cases underwent retroperitoneal laparoscopic surgeries. Histopathologic examination confirmed the diagnosis of retroperitoneal bronchogenic cysts. There was no recurrence of the three cases during follow-up. Clinical Discussion: A retroperitoneal bronchogenic cyst is mostly asymptomatic. It can be found in adults with variable findings in computed tomography. It can be likely ignored and misdiagnosed as an adrenal tumor. Conclusion: The tests of CA 19-9 and CA 24-2 could help diagnose retroperitoneal bronchogenic cysts. Retroperitoneal laparoscopic surgery is recommended for the treatment of retroperitoneal bronchogenic cysts with a favorable prognosis.

Correlation of psoas major muscle morphology with function and clinical symptoms in patients with symptomatic multilevel lumbar spinal stenosis.

OBJECTIVE: This study was performed to quantify the morphological characteristics of the psoas major muscle in patients with symptomatic multilevel degenerative lumbar spinal stenosis (SMLSS) and assess the correlations of these morphological characteristics with function and clinical symptoms. METHODS: One hundred fourteen patients diagnosed with SMLSS (≥ 3 segments) were included. The patients' presenting symptoms were assessed with the Oswestry Disability Index (ODI), and visual analogue scale (VAS) scores were recorded. The morphology of the psoas major was evaluated at the L3/4 intervertebral disc level in three ways: by measuring (i) the psoas muscle mass index (PMI); (ii) the mean muscle attenuation (Hounsfield units, HU); and (iii) the morphologic change of the psoas major (mean ratios of the short axis to the long axis of the bilateral psoas major). RESULTS: Men had a higher PMI than women (p = 0.001). Patients with severe disability had a significantly lower PMI (p = 0.002) and muscle attenuation (p = 0.001). The PMI and muscle attenuation were significantly higher in the patients with no or mild back pain (both p < 0.001). In the univariable and multivariable analyses, a greater HU value was associated with a higher functional status as assessed by the ODI (p = 0.002), and a higher PMI was associated with less severe back pain as measured by the VAS score (p < 0.001). CONCLUSION: This study showed that muscle attenuation of psoas major positively correlated with the functional status and PMI negatively correlated with low back pain severity in patients diagnosed with SMLSS. Future prospective studies are needed to evaluate whether improvement in such muscle parameters through physiotherapy programs can alleviate the clinical symptoms and improve the functional status of patients with SMLSS.

Hsa_circ_0001326 inhibited the proliferation, migration, and invasion of trophoblast cells via miR-145-5p/TGFB2 axis.

PROBLEM: Preeclampsia (PE) is an obstetric disease involving multiple systems, which account for maternal and fetal complications and increased mortality. Circular RNAs (circRNAs) were recently deemed to associate with the pathogenesis of PE. This study aims to clarify the correlation between circRNA hsa_circ_0001326 and PE and explore its biological function in PE. METHOD OF STUDY: The expression of hsa_circ_0001326 in PE placentas was detected by real-time quantitative PCR (qRT-PCR). After overexpressing or inhibiting hsa_circ_0001326 in trophoblast cells, the cell growth, migration, and invasion were evaluated by Cell Counting Kit-8 (CCK-8) and transwell assays. Western blot assay was applied to detect the epithelial-mesenchymal transition (EMT) proteins, E-cadherin and Vimentin. Furthermore, a dual-luciferase reporter assay was applied to verify the binding sites of hsa_circ_0001326, miR-145-5p, and transforming growth factor beta 2 (TGFB2). RESULTS: Hsa_circ_0001326 was found to be higher expressed in PE placentas than in normal placentas. Furthermore, hsa_circ_0001326 played a negative regulating role in trophoblast cell viability, migration, and invasion. Overexpression of hsa_circ_0001326 inhibited the viability, migration, and invasion of trophoblast cells, while inhibition of hsa_circ_0001326 showed opposite effects. Mechanistically, hsa_circ_0001326 sponged miR-145-5p to elevate TGFB2 expression in trophoblast cells. CONCLUSION: This study provided evidence that the up-regulated hsa_circ_0001326 in PE restrained trophoblast cells proliferation, migration, and invasion by sponging miR-145-5p to elevate TGFB2 expression. Our results might provide a novel insight into the role of hsa_circ_0001326 in the pathogenesis of PE.

Adrenocortical carcinoma with venous tumor invasion: is there a role for mini-invasive surgery?

OBJECTIVE: This study aims to investigate early oncologic outcomes in patients with adrenocortical carcinoma (ACC) with venous invasion (VI) treated using both open and mini-invasive approaches. PATIENTS AND MATERIALS: We conducted a retrospective analysis of 4 international referral center databases, including all the patients undergoing adrenalectomy for ACC with VI from January 2007 to March 2020. According to CT scan or MRI, the tumor thrombus was classified into four levels: (1) adrenal vein invasion; (2) renal vein invasion; (3) infra-hepatic Inferior vena cava (IVC); and (4) retro-hepatic IVC. In addition, we divided our patients into patients who had undergone open surgery and mini-invasive surgery. RESULTS: We identified 20 patients with a median follow-up of 12 months. The median tumor size was 110mm. ENSAT stage was II in 4 patients, III in 13 patients, and IV in 3 patients. Tumor thrombus extended in the adrenal vein (n=5), renal vein (n=1), infra-hepatic IVC (n=9), or into the retro-hepatic IVC (n=5). Ten patients were treated with a mini-invasive approach. The patient treated with an open approach reported a more aggressive disease. The two groups did not differ in surgical margins, surgical time, blood losses, complications, and length of stay. The prognosis resulted worse in the patient undergoing open. Kaplan-Meier analysis indicated a difference in OS for the patients stratified by ENSAT stage (Log-rank p=0.011); we also reported a difference in DFS for patients stratified for thrombus extension (p=0.004) and ENSAT stage (p<0.001). CONCLUSION: The DFS of patients with VI from ACC is influenced by the staging and the extension of the venous invasion; the staging influences the OS. The mini-invasive approach seems feasible in selected patients; however, further studies investigating the oncological outcomes are needed. A mini-invasive approach for adrenal tumors with venous invasion is an explorable option in very selected patients.

Characteristics associated with registration and management of the 686 Program among schizophrenia patients in China: A cross-sectional study.

The 686 Program has covered mainland China but lacks empirical research. We aimed to examine potential influencing factors associated with the registration and management of the Program. 3993 patients with schizophrenia discharged in 2019 were included. We found that approximately two-thirds of patients were registered. 88.9 % registered patients accepted the follow-up management. Males, unemployment, lower education, longer duration of illness, more hospitalization positively affected the registration and management. Individuals with violent behavior and local Hukou were more likely to be registered. Future evaluation of the Program should take these factors into account.
