Purpose: Chronic renal failure (CRF) is associated with impairment of hippocampal neurons. This study investigated the effect of PERK-eIF2α-ATF4 pathway in CRF.Methods: Rat CRF model was established and rat hippocampal neurons were separated. Xanthine Oxidase method, fluorescence spectrophotometry and flow cytometry were applied to detect superoxide dismutase (SOD) content, reactive oxygen species (ROS) level and apoptosis in hippocampal neurons, respectively. The levels of phosphorylated (p)-PERK, phosphorylated (p)-eIF2α, CHOP, Bax, C-Caspase-3 and Bcl-2 in rats were measured using Western blot. Then, the neurotoxicity of serum from CRF rats was assessed in rat hippocampal neurons after treatment with rat CRF serum and transfection with or without PERK overexpression or knockdown plasmid.Results: SOD activity was reduced, while ROS level and apoptosis rate were increased in hippocampal tissues of CRF rats. PERK-eIF2α-ATF4 and apoptosis pathways were activated in CRF rats. Cells treated with serum from CRF rats showed increases in apoptosis rate and LDH and ROS levels, and decreases in cell viability and SOD activity. However, overexpressed PERK could reverse the cytotoxic effect of serum from CRF rats. PERK overexpression could enhance the activation of PERK-eIF2α-ATF4 pathway in hippocampal neurons induced by serum from CRF rats. Furthermore, PERK overexpression could alleviate the increases in CHOP, Bax, C-Caspase-3 expressions and the reduction of Bcl-2 expression in hippocampal neurons induced by serum from CRF rats.Conclusion: PERK-eIF2α-ATF4 pathway induced by increased endoplasmic reticulum stress may alleviate CRF-induced hippocampal neuronal damage.

Background Postoperative renal function impairment represents a main limitation for delivering adjuvant chemotherapy after radical nephroureterectomy (RNU). Objective To create a model predicting renal function decline after minimally invasive RNU. Design, setting, and participants A total of 490 patients with nonmetastatic UTUC who underwent minimally invasive RNU were identified from a collaborative database including 17 institutions worldwide (February 2006 to March 2020). Renal function insufficiency for cisplatin-based regimen was defined as estimated glomerular filtration rate (eGFR) 50 ml/min/1.73 m2 (n = 361) were geographically divided into a training set (n = 226) and an independent external validation set (n = 135) for further analysis. Outcome measurements and statistical analysis Using transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) guidelines, a nomogram to predict postoperative eGFR Results and limitations The model that incorporated age, body mass index, preoperative eGFR, and hydroureteronephrosis was developed with an area under the curve of 0.771, which was confirmed to be 0.773 in the external validation set. The calibration curve demonstrated good agreement. Besides, the model was converted into a risk score with a cutoff value of 0.583, and the difference between the low- and high-risk groups both in overall death risk (hazard ratio [HR]: 4.59, p Conclusions A nomogram incorporating immediately available clinical variables can accurately predict renal insufficiency for cisplatin-based adjuvant chemotherapy after minimally invasive RNU and may serve as a tool facilitating patient selection. Patient summary We have developed a model for the prediction of renal function loss after radical nephroureterectomy to facilitate patient selection for perioperative chemotherapy.

Tinea capitis is still common in developing countries, such as China. Its pathogen spectrum varies across regions and changes over time.This study aimed to clarify the current epidemiological characteristics and pathogen spectrum of tinea capitis in China.A multicentre, prospective descriptive study involving 29 tertiary hospitals in China was conducted. From August 2019 to July 2020, 611 patients with tinea capitis were enrolled. Data concerning demography, risk factors and fungal tests were collected. When necessary, the pathogens were further identified by morphology or molecular sequencing in the central laboratory.Among all enrolled patients, 74·1% of the cases were in patients aged 2-8 years. The children with tinea capitis were mainly boys (56·2%) and were more likely than adults to have a history of animal contact (57·4% vs. 35·3%, P = 0·012) and zoophilic dermatophyte infection (73·5% vs. 47%). The adults were mainly female (83%) and were more likely than children to have anthropophilic agent infection (53% vs. 23·9%). The most common pathogen was zoophilic Microsporum canis (354, 65·2%), followed by anthropophilic Trichophyton violaceum (74, 13·6%). In contrast to the eastern, western and northeastern regions, where zoophilic M. canis predominated, anthropophilic T. violaceum predominated in central China (69%, P 0·001), where the patients had the most tinea at other sites (20%) and dermatophytosis contact (26%) but the least animal contact (39%). Microsporum ferrugineum was the most common anthropophilic agent in the western area, especially in Xinjiang province.Boys aged approximately 5 years were the most commonly affected group. Dermatologists are advised to pay more attention to the different transmission routes and pathogen spectra in different age groups from different regions.

Circadian dysregulation involves malignant tumor initiation and progression, but the understanding of circadian rhythm's roles in bladder cancer (BCa) remains insufficient. The circadian rhythm-related genes were collected and clustered based on the Cancer Genome Atlas (TCGA), and the clustering was significantly associated with the prognosis and risk clinicopathological features. Through genomic difference analysis and gene pairing, a circadian rhythm-related signature was successfully established. Kaplan-Meier survival analysis and time-dependent receiver operating curves displayed that the prognosis model was a reliable prognosis biomarker both in the training cohort (n = 396, P = 2.687e-10) and external validation cohort (n = 224, P = 1.45e-02). The patients with high risk have high immune infiltration and high expression of immune checkpoint genes, which partly account for the poor prognosis. TIDE algorithm and the validation in IMvigor210 cohort indicated that the risk signature was a promising marker for the immunotherapeutic response. The risk model could also predict the therapeutic response of cisplatin, which was validated in the Genomics of Drug Sensitivity in Cancer database (P = 0.0049), TCGA (P = 0.038), and T24 BCa cells treated with cisplatin. The functional enrichment showed the risk model was significantly correlated with some malignant phenotypes, such as angiogenesis, epithelial-mesenchymal transition, and KRAS signaling pathway. Totally, we proposed a novel circadian rhythm-related signature for prognosis evaluation, which also helped to predict the immune infiltration and cisplatin sensitivity in BCa.

Neutrophilic asthma (NA) is a severe type of steroid resistant asthma, and so far the immune mechanisms underlying NA are not clear. In this article, we performed a comprehensive assessment of Th-cell subsets and cytokines in severe NA patients. A total of 13 healthy individuals and 31 severe asthma patients were enrolled in this study. Refractory asthma patients were defined as those with eosinophilic asthma (EA, accounted for 32% of asthmatic patients) or NA (68%) according to sputum neutrophil/eosinophil counts or blood eosinophils. Th-cell subsets in peripheral blood mononuclear cells (PBMCs) were analyzed by flow cytometry, and cytokines were detected by cytometric bead array (CBA). The results showed significant differences were observed in Th-cell phenotypes, where the number of Th1 cells were reduced and the numbers of Th2 cells were increased in NA and EA groups, respectively, when compared with healthy controls. Th17 cells were not strongly associated with severe neutrophilic asthma. The frequencies of mucosal-associated invariant T (MAIT) cells were strikingly reduced in severe asthma patients, especially in the NA group. This NA group also showed increased levels of IL-17A, IL-17F, TNF-α, and IL-6 in serum and increased levels of IL-17A, IL-17F, IFN-γ, TNF-α, IL-1β, IL-5, IL-6, and IL-8 in sputum. In addition, sputum IL-6 was positively correlated with TNF-α, IFN-γ, IL-17A, and IL-8. Our results uncovered a controversial role for Th17 cells, which were reduced in severe asthma patients. Severe neutrophilic asthma was associated with a striking deficiency of MAIT cells and high pro-inflammatory cytokine levels.

Background Delineation of clinical target volume (CTV) for radiotherapy is a time‐consuming and labor‐intensive work. This study aims to propose a novel convolutional neural network (CNN)‐based model for fast auto‐segmentation of CTV. To evaluate its performance and clinical utility, a blind randomized validation method was used. Methods Our proposed model was based on the generally accepted U‐Net architecture using computed tomography slices with CTV contours delineated by experienced radiation clinicians from 135 rectal patients receiving neoadjuvant radiotherapy. The Dice similarity coefficient (DSC) and 95th percentile Hausdorff distance (95HD) were used to measure segmentation performance. The validated dataset of additional 20 patients for clinical evaluation by 10 experienced oncology clinicians from 7 centers was randomly and blindly divided into two groups for clinicians' scoring and Turing test, respectively. Second evaluation was performed with different randomization after 2 weeks. Results The mean DSC and 95HD values of the proposed model were 0.90 ± 0.02 and 8.11 ± 1.93 mm for CTV of rectal cancer patients, respectively. The average time for automatic segmentation in the validation groups was 15 s per patient. By clinicians' scoring, the AI model performed better than manually delineating, though the differences were not significant (Week 0: 2.59 vs. 2.52, p = 0.086; Week 2: 2.55 vs. 2.47, p = 0.115). Additionally, the mean positive rates in the Turing test were 40.5% in Week 0 and 45.2% in Week 2, which demonstrated the great intelligence of our model. Conclusions Our proposed model can be used clinically for assisting contouring of CTVs in rectal cancer patients receiving neoadjuvant radiotherapy, which improves the efficiency and consistency of radiation clinicians' work., This study first developed an auto‐segmentation system using U‐Net deep learning architecture in patients receiving neoadjuvant radiotherapy and obtained great measurement performance. Besides, we first reported a blind system for clinical evaluation, including clinicians' scoring and Turing test by multicenter radiologists, which can eliminate inter‐ and intra‐observer discrepancy as much as possible. Our proposed methods may be helpful for the assessment of AI‐assisted models in clinical practice.

Purpose: We assessed whether perioperative circulating tumor DNA (ctDNA) could be a biomarker for early detection of molecular residual disease (MRD) and prediction of postoperative relapse in resected non–small cell lung cancer (NSCLC). Experimental Design: Based on our prospective, multicenter cohort on dynamic monitoring of ctDNA in lung cancer surgery patients (LUNGCA), we enrolled 950 plasma samples obtained at three perioperative time points (before surgery, 3 days and 1 month after surgery) of 330 stage I–III NSCLC patients (LUNGCA-1), as a part of the LUNGCA cohort. Using a customized 769-gene panel, somatic mutations in tumor tissues and plasma samples were identified with next-generation sequencing and utilized for ctDNA-based MRD analysis. Results: Preoperative ctDNA positivity was associated with lower recurrence-free survival (RFS; HR = 4.2; P < 0.001). The presence of MRD (ctDNA positivity at postoperative 3 days and/or 1 month) was a strong predictor for disease relapse (HR = 11.1; P < 0.001). ctDNA-based MRD had a higher relative contribution to RFS prediction than all clinicopathologic variables such as the TNM stage. Furthermore, MRD-positive patients who received adjuvant therapies had improved RFS over those not receiving adjuvant therapy (HR = 0.3; P = 0.008), whereas MRD-negative patients receiving adjuvant therapies had lower RFS than their counterparts without adjuvant therapy (HR = 3.1; P < 0.001). After adjusting for clinicopathologic variables, whether receiving adjuvant therapies remained an independent factor for RFS in the MRD-positive population (P = 0.002) but not in the MRD-negative population (P = 0.283). Conclusions: Perioperative ctDNA analysis is effective in early detection of MRD and relapse risk stratification of NSCLC, and hence could benefit NSCLC patient management.

Objective To identify barriers to seeking health care among returning travellers with malaria with the aim of developing targeted interventions that improve early health care-seeking behaviour, diagnosis and treatment. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review of published medical literature, selecting studies that investigated and reported barriers to seeking health care among returning travellers and migrants with malaria. In total, 633 articles were screened, of which four studies met the inclusion criteria after a full-text review. Results The four studies reported barriers to seeking healthcare among returning travellers in China, the USA, Thailand, and the Dominican Republic. Three studies had an observational design. The identified barriers were summarized based on the appraisal delay, illness delay, and utilization delay stages. During appraisal delays, low awareness of malaria was the most significant factor. Once the patient assessed that he or she was ill, belonging to a specific minority ethnicity, being infected with P. vivax, and receiving a low level of social support were predictors of delayed health care-seeking. Finally, the most significant factor associated with utilization delays was the monetary cost. Conclusion The health care-seeking behaviour of returning travellers with malaria should be further investigated and improved. Addressing the identified barriers and gaps in health care-seeking behaviour among returning travellers with malaria, particularly among groups at high risk of travel-associated infections, is important to prevent severe disease and deaths as well as secondary transmission and epidemics.

Non-obstructive azoospermia (NOA) is among the most severe factors for male infertility, but our understandings of the latent biological mechanisms remain insufficient. The single-cell RNA sequencing (scRNA-seq) data of 432 testicular cells isolated from the patient with NOA was analyzed, and the cell samples were grouped into 5 cell clusters. A sum of 455 cell markers was identified and then included in the protein-protein interaction network. The Top 5 most critical genes in the network, including CCT8, CDC6, PSMD1, RPS4X, RPL36A, were selected for the diagnosis model construction through the random forest (RF). The RF model was a strong classifier for NOA and obstructive azoospermia (OA), which was validated in the training cohort (n = 58, AUC = 1) and external validation cohort (n = 20, AUC = 0.9). We collected the seminal plasma samples and testicular biopsy samples from 20 OA and 20 NOA cases from the local hospital, and the gene expression was detected via Real-Time quantitative Polymerase Chain Reaction (RT-qPCR) and Immunohistochemistry. The RF model also exhibited high accuracy (AUC = 0.725) in the local cohort. In summary, a novel gene signature was developed and externally validated based on scRNA-seq analysis, providing some new biomarkers to uncover the underlying mechanisms and a promising clinical tool for diagnosis in NOA.

We trained and evaluated a U-ResNet model to provide fast and consistent auto-segmentation.Methods: We collected 160 patientsâ CT scans with breast cancer who underwent breast-conserving surgery (BCS) and were treated with radiotherapy. CTV and OARs were delineated manually and were used for model training. The dice similarity coefficient (DSC) and 95th percentile Hausdorff distance (95HD) were used to assess the performance of our model. CTV and OARs were randomly selected as ground truth (GT) masks, and artificial intelligence (AI) masks were generated by the proposed model. Two clinicians randomly compared CTV score differences of the contour. The consistency between two clinicians was tested. Time cost for auto-delineation was evaluated.Results: The mean DSC values of the proposed method were 0.94, 0.95, 0.94, 0.96, 0.96 and 0.93 for breast CTV, contralateral breast, heart, right lung, left lung and spinal cord, respectively. The mean 95HD values were 4.31mm, 3.59mm, 4.86mm, 3.18mm, 2.79mm and 4.37mm for the above structures, respectively. The average CTV scores for AI and GT were 2.89 versus 2.92 when evaluated by oncologist A (P=0.612), and 2.75 versus 2.83 by oncologist B (P=0.213), with no statistically significant differences. The consistency between two clinicians was poor (kappa=0.282). The time for auto-segmentation of CTV and OARs was 10.03 s.Conclusion: Our proposed model (U-ResNet) can improve the efficiency and accuracy of delineation compared with U-Net, performing equally well with the segmentation generated by oncologists.Keywords: clinical target volume, organ at risk, auto-segmentation, breast cancer radiotherapy, clinical evaluation

To explore the clinical significance of the perioperative counts of circulating tumor cells (CTCs), mesenchymal CTCs (MCTCs), and CTC- white blood cells (WBCs) in renal cell carcinoma patients. A total of 131 patients with renal cancer who underwent operation excision from our hospital were enrolled. In addition, 20 patients with benign renal diseases were recruited as a control. Blood samples were collected from the 131 patients, before operation and 3 months after surgery. Samples were also obtained simultaneously from the control group. CanPatrol CTC detection technique was used to enrich and identify CTCs, MCTCs, and CTC-WBCs. All enrolled patients were T1-3N0M0. From these, 52 patients with renal cancer underwent radical resection, while other 79 patients underwent nephron-sparing surgery. The positive rate of CTC, MCTC, and CTC-WBC before surgery were 95.4% (125/131), 61.1% (80/131), and 11.5% (15/131), respectively. Preoperative total CTCs, MCTCs, or CTC-WBCs were poorly correlated with patients’ parameters. Preoperative CTC, MCTC, or CTC-WBC showed no association with progression-free survival (PFS). In contrast, postoperative total CTCs (≥6), positive MCTCs, and positive CTC-WBCs significantly correlated with recurrence and metastasis. These results remained independent indicators for worse PFS. In addition, the increased CTC and MCTC count after surgery also correlated with unfavorable PFS. The detection of six or more total CTCs, MCTC, or CTC-WBCs in peripheral blood after surgery might help to identify a subset of patients that have higher recurrent risk than the overall population of patients with at different stages of renal cancer.

Purpose: To compare the efficacy and safety of plasma kinetic enucleation of the prostate (PKEP) with holmium laser enucleation of the prostate (HoLEP) for treatment of benign prostatic hyperplasia (BPH). Methods: A total of 160 patients with indications for the surgical treatment of BPH were randomly assigned to receive either PKEP or HoLEP prospectively. Baseline characteristics, perioperative data, and postoperative outcomes of the patients were recorded. One hundred twenty-six (78.75%) patients (PKEP 64 vs HoLEP 62) completed the 3-year follow-up assessment. Results: Patients in both groups had similar baseline characteristics. Compared with PKEP, HoLEP was associated with shorter operative time as well as take-out time, lower perioperative hemoglobin decrease, and shorter bladder irrigation time, catheterization time, and hospital stay time. PKEP was superior to HoLEP in terms of the noise of the machine and hospitalization expenses. There were no significant differences in enucleating time, resected weight, and serum sodium levels. Both groups achieved satisfactory results and maintained improvement from baseline in terms of maximum urinary flow rate (Qmax), International Prostatic Symptomatic Score, quality of life, and postvoid residual at 3-year follow-up, with no significant differences between the two procedures. Except for re-catheterization rate, postoperative data such as transrectal ultrasound volume, International Index of Erectile Function-5, and follow-up scores of the flexible cystourethroscopy results, as well as the acute and mid-to long-term complications after surgery, were statistically similar. Conclusion: The 3-year follow-up data of this randomized trial confirmed that both PKEP and HoLEP were effective and safe surgical procedures for the transurethral management of BPH. HoLEP presented certain advantages compared to PKEP, such as reduced operative duration, decreased risk of blood loss, and less bladder irrigation, hospital stay time, and re-catheterization rate, whereas PKEP had lower noise and no additional laser cost.

Although thoracoscopy has characteristics such as a small surgical incision and low stress response, post-surgical pain after a thoracoscopic operation is no less than that after a thoracotomy. Moreover, poor post-surgical pain management is likely to cause an increased incidence of postoperative pulmonary complications (PPCs) and chronic post-surgical pain. The serratus anterior plane block (SAPB) is a regional anesthesia method whereby local anesthetics (LAs) are injected into the serratus anterior space to block the lateral cutaneous branch of the intercostal nerve, long thoracic nerve, and dorsal thoracic nerve. The block range of the SAPB covers the incisions of video-assisted thoracoscopic surgery (VATS) and the site of the chest tube, which are often located in the antero-lateral chest wall. Therefore, the SAPB can achieve effective analgesia in VATS. For example, 0.125% to 0.25% levobupivacaine (20-25 ml) is widely used for thoracic surgery, which can achieve effective analgesia and avoid adverse reactions. Moreover, it has advantages compared with thoracic segmental epidural block (TEA) and thoracic paravertebral block (TPVB), such as simple operation, increased safety, fewer complications, and hemodynamic stability. In addition, adequate analgesia is helpful for pulmonary function recovery and reduces the incidence of PPCs. This article introduces the anatomical mechanism of the SAPB, diverse operation approaches, how to choose drugs and adjuvants, and the resulting impacted area range. It summarizes the advantages and disadvantages of the SAPB compared with other analgesic methods and posits that the SAPB is beneficial to the recovery of postoperative lung function, which provides more options for postoperative analgesia after VATS.

Intra-tumor heterogeneity (ITH) was a potential mechanism of progression and drug resistance in bladder cancer (BCa). However, the understanding of ITH in BCa remains insufficient. Single-cell RNA sequencing (scRNA-seq) profiles of 2075 cells were analyzed, and 2940 cell markers were screened. The ITH of 396 cases was evaluated, and 96 ITH-related genes were identified. Based on the gene-pair strategy, 96 genes were cyclically paired, and an 8-gene-pair model was successfully established to evaluate the overall survival of BCa through Lasso and multivariate Cox regressions. The risk model showed high predictive value in the training dataset (n = 396, p = 0) and external validation datasets (n = 165, p = 2.497e-02; n = 224, p = 3.423e-02). The model was also valuable for the prediction of clinical treatment outcomes. Totally, a prognostic model based on scRNA-seq and ITH was successfully constructed and validated in large cohorts, providing novel clues for ITH study of BCa.

BACKGROUND: Vaginitis is one of the most common gynecological diseases in women and may severely affect the quality of life in patients. However, very few studies have investigated aerobic vaginitis (AV) in pregnant women, and our study was designed to identify the pathogen profile, clinical importance, and risk factors of AV in pregnancy. METHODS: This was a retrospective cohort study enrolling 685 women who attended our hospital between July 2018 and June 2020. Based on the incidence of AV, enrolled women were divided into an AV group and healthy control group, and demographic and clinical characteristics were retrospectively collected by two independent investigators. Some pathogens of AV were tested using quantitative real-time polymerase chain reaction for higher accuracy. Pregnancy outcomes were also retrospectively collected. Univariable and multivariable logistic regression analysis was used to determine the risk factors of AV incidence and adverse pregnant outcomes. RESULTS: Enrolled women were divided into an AV group of 182 women and healthy control group of 503 women. The proportions of women with a history of cesarean delivery and history of vaginal infection differed between the groups (P=0.002 and

Hypertension (HTN) and osteoarthritis (OA) are frequent in middle-aged and elderly people, and the co-occurrence of these two diseases is common. However, the pathogenesis of the multimorbidity of both diseases and the relation with sleep quality, hyperlipemia, and hyperglycemia is unclear. We conducted a cross-sectional study to make sense of the multimorbidity of HTN and OA and the relation with sleep quality, hyperlipemia, and hyperglycemia. The relation between sleep quality and OA and its joint effect with hyperlipemia or hyperglycemia was evaluated with logistic regression models. The additive interaction was assessed with the relative excess risk due to interaction (REEI), the attributable proportion (AP), and the synergy index (S). According to this research in a remote rural area, approximately 34.2% of HTN patients are accompanied with OA and 49.1% are suffering poor sleep. Both hyperlipemia/hyperglycemia and sleep quality were related to OA prevalence with crude ORs of 1.43 (95% CI 1.014–2.029) and 1.89 (95% CI 1.411–2.519, P

The coronavirus disease 2019 (COVID-19) epidemic is a major public health emergency characterized by fast spread, a wide range of infections, and enormous control difficulty. Since the end of December 2019, Wuhan has become the first core infection area of China's COVID-19 outbreak. Since March 2020, the domestic worst-hit areas have moved to the Heilongjiang Province due to the increased number of imported COVID-19 cases. Herein, we reported the major COVID-19 outbreak, which caused a rebound of the epidemic in Harbin, China. After the rebound, different levels of causes for the recurrence of COVID-19, including city-level, hospital-level, and medical staff-level cause, were investigated. Meanwhile, corresponding countermeasures to prevent the recurrence of the epidemic were also carried out on the city level, hospital level, and medical staff level, which eventually showed the effect of infection control function in a pandemic. In this study, we described the complete transmission chain, analyzed the causes of the outbreak, and proposed corresponding countermeasures from our practical clinical experience, which can be used as a valuable reference for COVID-19 control.

The study drew attention to the therapeutic effects of cold snare polypectomy guided by a deep convolutional neural network- (CNN-) based abdominal CT and hot snare polypectomy (HSP) on colonic and rectal polyps. Specifically, 90 patients were enrolled into a blank group, a control (Ctrl) group, and an experimental group. The blank group accepted HSP, the Ctrl accepted cold snare polypectomy, and the experimental group accepted cold snare polypectomy guided by deep CNN-based CT images. It was found that the experimental group had the lowest false-positive rate (9.2%) in polyp detection in contrast with the Ctrl (21.4%) and the blank group (52.3%) P < 0.05 . The complete resection rate of large polyps in the experimental group was the highest P < 0.05 , and its operation time (2.91 ± 0.75 min) was obviously shorter versus the blank group (6.18 ± 1.19 min) P < 0.05 . In conclusion, the cold snare polypectomy under the guidance of deep CNN-based CT has a relatively high complete resection rate and detection accuracy of polyps with a low complication rate, which can be adopted clinically.

We utilized dynamic functional network connectivity (dFNC) analysis to compare participants with obsessive–compulsive disorder (OCD) with their unaffected first‐degree relative (UFDR) and healthy controls (HC). Resting state fMRI was performed on 46 OCD, 24 UFDR, and 49 HCs, along with clinical assessments. dFNC analyses revealed two distinct connectivity states: a less frequent, integrated state characterized by the predominance of between‐network connections (State I), and a more frequent, segregated state with strong within‐network connections (State II). OCD patients spent more time in State II and less time in State I than HC, as measured by fractional windows and mean dwell time. Time in each state for the UFDR were intermediate between OCD patients and HC. Within the OCD group, fractional windows of time spent in State I was positively correlated with OCD symptoms (as measured by the obsessive compulsive inventory‐revised [OCI‐R], r = .343, p, We identified several dFNC differences in OCD and UFDR that may be useful for establishing biomarkers of an OCD endophenotype. First, OCD patients had abnormal temporal properties which correlated with clinical features, which were shared with their UFDR. Second, we found similar connectivity patterns for UFDR and OCD within a dFNC state characterized by between‐network integration. These results provide new insights into the pathophysiology of OCD patients and indicate dynamic functional connectivity measures that could be used as biomarker to identify those at risk.

Introduction Thyroid nodules are scattered lesions caused by abnormal local growth of thyroid cells. In recent years, their prevalence rate has been rising gradually, and the probability of cancerations has also been increasing gradually. Therefore, we must pay more attention to them and carry out early intervention. However, at present, most of the intervention measures for patients with thyroid nodules are mainly clinical observation and follow-up, and no clear and effective drug intervention therapy has been proposed. The curative effect of acupuncture on thyroid nodules has been proved clinically. However, as there is no clear mechanism of action, no specific operation methods or Suggestions, it is necessary to make a systematic evaluation of acupuncture therapy, so as to lay a foundation for further research in the future. Methods and analysis The following databases will be searched from their inception to June 2020: Electronic database includes PubMed, Embase, Cochrane Library, Web of Science, Nature, Science online, Chinese Biomedical Database WanFang, VIP medicine information, and China National Knowledge Infrastructure (CNKI). Primary outcomes: Color ultrasound of thyroid and cervical lymph nodes, FT3, FT4, TSH, TGAB, TPOAB, insulin resistance index (HOMA-IR). Data will be extracted by 2 researchers independently, risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0.

BACKGROUND: This study aimed to determine how concomitant tricuspid annuloplasty (TAP) affects the clinical outcomes of patients undergoing totally endoscopic mitral valve surgery. METHODS: This was a single-centre, retrospective study. Between January 2019 and June 2020, 143 patients who underwent totally endoscopic mitral valve surgery in our institution were enrolled. Ninety-two patients who underwent isolated mitral valve surgery were categorized into the minimally invasive mitral valve surgery (MIMVS) group (n=92), and patients who underwent mitral valve surgery with concomitant TAP were categorized into the MIMVS-TAP (n=51) group. Clinical data were collected from all patients, including demographic and perioperative data. We conducted propensity score matching (PSM) by using one-to-one ratio nearest-neighbour matching for baseline demographic data and tricuspid valve-related parameters. Forty patients in each group were matched in this way. Parametric and nonparametric tests were performed for data analysis. RESULTS: Statistically, postoperative mortality within 30 days was not significantly different between the two groups (P=1). No differences were found in serious adverse events, such as stroke or third-degree conduction block, between the two groups after 1:1 PSM (P=1 and P=0.480, respectively). The mean operation time for the MIMVS+TAP group was longer (232.13±36.05 min) than that for the MIMVS group (204.25±28.49 min; P

Nodal-skip metastasis (NSM) is found in esophageal squamous cell carcinoma (ESCC), but its prognostic role is controversial. This study aimed to investigate the prognostic value of NSM for thoracic ESCC patients. Categorization of NSM was according to the N groupings of Japan Esophagus Society (JES) staging system, which is dependent on tumor location. Using the Kaplan–Meier method and Cox-regression analysis, this study retrospectively analyzed the overall survival (OS) for 2325 ESCC patients after radical esophagectomy at three high-volume esophageal cancer centers. Predictive models also were constructed. The overall NSM rate was 20% (229/1141): 37.4% in the in upper, 12.9% in the middle, and 22.2% in the lower thoracic ESCC. The patients with NSM always had a better prognosis than those without NSM. Furthermore, NSM was an independent prognostic factor for thoracic ESCC patients (hazard ratio [HR], 0.633; 95% confidence interval [CI], 0.499–0.803; P

Globally, postpartum hemorrhage (PPH) is the leading cause of maternal death. Women with immune thrombocytopenia (ITP) are at increased risk of developing PPH. Early identification of PPH helps to prevent adverse outcomes but is underused because clinicians do not have a tool to predict PPH for women with ITP. We therefore conducted a nationwide multicenter retrospective study to develop and validate a prediction model of PPH in patients with ITP. We included 432 pregnant women (677 pregnancies) with primary ITP from 18 academic tertiary centers in China from Jan 2008 to Aug 2018. A total of 157 (23.2%) pregnancies experienced PPH. The derivation cohort included 450 pregnancies. For the validation cohort, we included 117 pregnancies in the temporal validation cohort and 110 pregnancies in the geographical validation cohort. We assessed 25 clinical parameters as candidate predictors and used multivariable logistic regression to develop our prediction model. The final model included seven variables and was named MONITOR (maternal complication, WHO bleeding score, antepartum platelet transfusion, placental abnormalities, platelet count, previous uterine surgery, and primiparity). We established an easy-to-use risk heatmap and risk score of PPH based on the seven risk factors. We externally validated this model using both a temporal validation cohort and a geographical validation cohort. The MONITOR model had an AUC of 0.868 (95% CI 0.828-0.909) in internal validation, 0.869 (95% CI 0.802-0.937) in the temporal validation, and 0.811 (95% CI 0.713-0.908) in the geographical validation. Calibration plots demonstrated good agreement between MONITOR-predicted probability and actual observation in both internal validation and external validation. Therefore, we developed and validated a very accurate prediction model for PPH. We hope that the model will contribute to more precise clinical care, decreased adverse outcomes, and better health care resource allocation. This article is protected by copyright.

This study aimed to explore the combined effects of hypertension and general or central obesity on the risk of ischemic stroke in a middle-aged and elderly population.Methods: The data of 11,731 participants (53.5 ± 10.5 years old) were analyzed from the Northeast China Rural Cardiovascular Health Study, 2012– 2013. General obesity (GO) was defined by body mass index (BMI); central obesity (CO) was measured by waist circumference (WC), waist-to-height ratio (WHtR) and waist-to-hip ratio (WHpR).Results: The overall prevalence of ischemic stroke was 3.1%. After adjusting for age and sex, the odds ratios for having ischemic stroke were 4.31 (3.14– 5.91) among subjects with hypertension, 1.79 (1.40– 2.30) with GO, 1.94 (1.54– 2.43), 1.98 (1.54– 2.53), and 1.65 (1.33– 2.06) with CO measured by WC, WHtR and WHpR, respectively. After full adjustment for potential confounders, the combinations of hypertension and obesity indices (including BMI, WC, WHtR and WHpR) were associated with the highest risk of ischemic stroke, especially in women, which were respectively 7.3-fold, 9.3-fold, 9.9-fold and 7.6-fold higher than that of individuals without both conditions.Conclusion: Our study results suggest that women with both hypertension and obesity, no matter defined by BMI, WC, WHtR or WHpR, were more likely to have ischemic stroke. A better understanding of the combined effects of these risk factors can help promote primary prevention in susceptible subgroups.Keywords: ischemic stroke, hypertension, general obesity, central obesity

In this study, we conducted a meta-analysis of published randomized clinical trials (RCTs) to analyze the analgesic effects of TEA versus TPVB after thoracoscopic surgery.Methods: We systematically searched RCTs published by October 26, 2020, in PubMed, EMBASE, and Cochrane library and conducted a meta-analysis to analyze the analgesic effects of TEA versus TPVB after thoracoscopic surgery. The primary measure was postoperative pain score, and the secondary measures were postoperative 24-hour usage of opioids, hypotension, postoperative nausea, and vomiting.Results: A total of 458 patients from five RCTs were included in this study. After thoracoscopic surgery, the numerical rating scale (NRS) score for resting pain was higher in the TPVB group than in the TEA group at 1– 2 hours and 4– 6 hours after surgery (MD = 0.44, 95% CI = 0.24 to 0.64, P < 0.0001, I2 = 0%; MD = 0.47, 95% CI = 0.23 to 0.70, P < 0.0001, I2 = 0%). The postoperative 24-hour usage of morphine was higher in the TPVB group than in the TEA group (SMD = 0.67; 95% CI = 0.03 to 1.31; P = 0.04; I2 = 84%). The incidence of hypotension was significantly lower in the TPVB group than in the TEA group (OR = 4.52; 95% CI = 2.03 to 10.10; P = 0.0002; I2 = 0%). No significant between-group difference was observed in postoperative nausea and vomiting (PONV).Conclusion: Compared with TPVB, TEA provides statistically significant but clinically unimportant short-term benefits following thoracoscopic surgery.Keywords: thoracic paravertebral block, thoracic epidural anesthesia, thoracoscopic surgery, meta-analysis

Summary Background Since 1997, epidemics of hand, foot, and mouth disease associated with enterovirus A71 (EV-A71) have affected children younger than 5 years in the Asia-Pacific region, including mainland China. EV-A71 vaccines have been licensed for use in children aged 6–71 months in China, but not for infants younger than 6 months. We aimed to assess the dynamics of maternal EV-A71 antibodies to inform choice of potential vaccination strategies to protect infants younger than 6 months, because they have a substantial burden of disease. Methods We did a longitudinal cohort study with mother–neonate pairs in local hospitals in southern China during 2013–18. We collected cord blood from neonates and venous blood from mothers at delivery. We followed up and collected blood samples from the children at ages 2, 4, 6, 12, 24, and 36 months and tested for the presence of neutralising antibodies against EV-A71 with virus neutralisation assays. Seropositivity, or protective titre, was defined as a neutralisation antibody titre of 16 or higher. We estimated the seroprevalence, geometric mean titre (GMT), and transfer ratio of maternal antibodies. We used a binomial distribution to derive the 95% CIs of seroprevalence. Seropositivity between mothers and neonates was compared by use of an agreement (κ), while GMTs were compared by use of paired Student's t tests. Findings Between Sept 20, 2013, and Oct 14, 2015, 1054 mothers with 1066 neonates were enrolled. The EV-A71 GMT was similar among pairs of neonates (22·7, 95% CI 20·8–24·9) and mothers (22·1, 95% CI 20·2–24·1; p=0·20). The mean transfer ratio of maternal antibodies was 1·03 (95% CI 0·98–1·08). Although 705 (66%) of 1066 neonates acquired protective concentrations of EV-A71 antibodies from mothers, these declined rapidly, with a half-life of 42 days (95% CI 40–44). The time to loss of protective immunity was extended to 5 months in neonates with mothers who had titres of 128 or higher. By age 30 months, 28% of children had become seropositive because of natural infection. Interpretation EV-A71 maternal antibodies were efficiently transferred to neonates, but declined quickly to below the protective threshold, particularly among those whose mothers had low antibody titres. Our findings suggest that maternal vaccination could be explored to provide neonatal protection against EV-A71 through maternal antibodies. Catch-up vaccination between ages 6 months to 5 years could provide protection to the approximately 30–90% of children that have not had natural EV-A71 infection by that age.

Proliferation of vascular smooth muscle cells (VSMCs) greatly contributes to vascular remodeling in hypertension. This study is to determine the roles and mechanisms of miR-135a-5p intervention in attenuating VSMC proliferation and vascular remodeling in spontaneously hypertensive rats (SHRs). MiR-135a-5p level was raised, while fibronectin type III domain-containing 5 (FNDC5) mRNA and protein expressions were reduced in VSMCs of SHRs compared with those of Wistar–Kyoto rats (WKYs). Enhanced VSMC proliferation in SHRs was inhibited by miR-135a-5p knockdown or miR-135a-5p inhibitor, but exacerbated by miR-135a-5p mimic. VSMCs of SHRs showed reduced myofilaments, increased or even damaged mitochondria, increased and dilated endoplasmic reticulum, which were attenuated by miR-135a-5p inhibitor. Dual-luciferase reporter assay shows that FNDC5 was a target gene of miR-135a-5p. Knockdown or inhibition of miR-135a-5p prevented the FNDC5 downregulation in VSMCs of SHRs, while miR-135a-5p mimic inhibited FNDC5 expressions in VSMCs of both WKYs and SHRs. FNDC5 knockdown had no significant effects on VSMC proliferation of WKYs, but aggravated VSMC proliferation of SHRs. Exogenous FNDC5 or FNDC5 overexpression attenuated VSMC proliferation of SHRs, and prevented miR-135a-5p mimic-induced enhancement of VSMC proliferation of SHR. MiR-135a-5p knockdown in SHRs attenuated hypertension, normalized FNDC5 expressions and inhibited vascular smooth muscle proliferation, and alleviated vascular remodeling. These results indicate that miR-135a-5p promotes while FNDC5 inhibits VSMC proliferation in SHRs. Silencing of miR-135a-5p attenuates VSMC proliferation and vascular remodeling in SHRs via disinhibition of FNDC5 transcription. Either inhibition of miR-135a-5p or upregulation of FNDC5 may be a therapeutically strategy in attenuating vascular remodeling and hypertension.

AIMS To evaluate the effectiveness of the hospital-family holistic care model based on the theory of 'Timing It Right' in caregivers of patients with permanent enterostomy. DESIGN A prospective randomized controlled trial. METHODS One hundred and twenty-five caregivers of patients with permanent enterostomy were recruited from 1 May 2017-31 August 2019. They were randomized into either intervention group (N = 62) or control group (N = 63). The control group received routine care and follow-up, while the intervention group received routine care, follow-up, and hospital-family holistic care intervention based on 'Timing It Right'. The care ability, psychological distress, and life quality of the caregivers were evaluated between the groups before the intervention, at discharge, and 3 and 6 months after discharge. RESULTS One hundred and eleven caregivers completed the study (88.8%). At 3 and 6 months after discharge, the care ability and life quality in the intervention group were significantly better than those in the control group (t = 8.506/9.783, t = 22.652/26.179, p

To access the diagnostic value of 3D-IOS in COPD.Methods: A total of 107 COPD patients and 61 healthy subjects as controls were chosen to collect and statistically analyze the data of R5, R5–R20, R20, X5 and Fres measured by broadband 3D-IOS and FEV1%pred, FVC%pred and FEV1/FVC by PFTs. The diagnostic value of broadband 3D-IOS parameters in COPD was evaluated by receiver operating characteristic curve (ROC). 3D-colored images used to show dynamic changes of respiratory resistance in COPD.Results: The COPD group showed significant increases in R5, R20, R5–R20 and Fres, and a decrease in X5 (P< 0.05). With the increase of GOLD grade, R5, R5–R20 and Fres increased whereas X5 decreased (P< 0.05). Compared with FEV1%pred, FVC%pred and FEV1/FVC in the COPD group, R5, R5–R20 and Fres were negatively collated (P< 0.05), whereas X5 was positively collated (P< 0.01). R20 was uncorrelated with the traditional lung function parameters (P> 0.05). Fres and FEV1/FVC (r=− 0.467), and X5 and FEV1%pred (r=0.412) showed the strongest correlation. The AUC of R5, R5–R20, X5 and Fres was 0.7808, 0.7659, 0.8947 and 0.9095, respectively. Typical 3D-colored images of COPD displayed a green pattern in the inhalation phase and yellow–red–blue graduation in the expiration phase.Conclusion: R5, R5-R20, X5 and Fres measured by broadband 3D-IOS can reflect the change of respiratory resistance in COPD. And they have good correlation with the traditional lung function parameters (FEV1%pred, FVC%pred, FEV1/FVC). Fres has the highest diagnostic accuracy. Comprehensive analysis of R5, R5–R20, Fres and X5 helps to determine the degree of respiratory obstruction in COPD. X5 and Fres can reflect changes in lung tissue compliance. 3D-colored images can visually show the change of respiratory resistance and reactance in COPD.Keywords: 3-dimensional impulse oscillometry, respiratory resistance, pulmonary function test, chronic obstructive pulmonary disease

Background To retrospectively assess the experience of day-surgery semi tubeless ultra-mini percutaneous nephrolithotomy (UMP) for the treatment of kidney stones by experienced surgeons. Methods Clinical data of 358 patients with kidney stones (254 males and 104 females; mean age: 59.60±11.70) who were performed UMP surgery in Shanghai Jiao Tong University School of Medicine affiliated Renji Hospital from June 2015 to December 2018. Patient demographics, operative data, complications, and readmission rates were recorded. Day-surgery UMP was defined as discharge of patients either the same day or within 24 h after surgery. Semi tubeless UMP was defined as no placement of DJ and nephrostomy tube after surgery. Results The average size of stones was 14.56±6.24 mm (range, 4-30 mm). There are solitary stones in 192 cases, multiple stones in 142 cases and 29 cases with Staghorn stones. F13 outer sheath was used for all operations; 358 patients completed UMP on the day of admission; 326 (91.06%) patients achieved same-day discharge or received overnight observation prior to discharge, and 32 patients (8.94%) required full admission (longer than 24 h). The readmission rate was 0.56% (2 patients). The postoperative complications within 1 week occurred in 36 (10.06%) patients, including 23, 10, 3 of grades I, II, IIIa complications (Clavien-System). The average operation time was 29.64 min and the hemoglobin drop were 13.42±9.55 g/L. The stone clearance rate was 91.62% (328/358). The semi tubeless rate war 95.25% (341/358). Conclusions For day-surgery semi tubeless UMP, experienced surgeons gain excellent patient outcomes in appropriately selected patients. Day-surgery semi tubeless UMP is worth promoting.

Objectives This multicenter retrospective study aimed to compare the effects of HES and gelatin (GEL) on the risk of post-OLT AKI. Method A total of 1,672 patients undergoing OLT were enrolled from major transplant centers in China between 2005 and 2013. These patients were divided into three groups: GEL, hydroxyethyl starch (HES), and GEL + HES group. Results There was no significant difference in the incidence of post-OLT AKI among the GEL, HES, and GEL + HES groups. The GEL + HES group had a lower incidence of stage II post-OLT AKI than the other two groups. Compared with patients receiving GEL, patients receiving HES did not harbor an increased risk of AKI. Our results showed that MELD score (adjusted odds ratio [OR], 1.579; 95% confidence interval [CI], 1.123–2.219; P = 0.009) and preoperative anemia (adjusted OR, 1.533; 95% CI, 1.212–1.939; P < 0.001) were independent risk factors for post-OLT AKI, and normal preoperative Scr level (vs abnormal; adjusted OR, 0.402; 95% CI, 0.222–0.729; P = 0.003) was independent protective factors for post-OLT AKI. Conclusion This large-scale multicenter retrospective study found that the intraoperative use of HES did not increase the overall incidence of post-OLT AKI in patients when compared with GEL, and whether to increase the risk of post-OLT AKI needs to be further explored.

Objective:The aim of this study was to investigate the changes in Chinese residents’ psychological state and its influencing factors after the Wuhan shutdown on January 23, 2020.Methods:Two surveys were conducted on February 1-5 and February 20-24, separately, using an online self-administrated questionnaire among 3145 and 3814 participants, respectively. Subjective indicators of daily-life changes include level of attention, risk of infection, impact of daily life, self-perceived health status, and mental health help-seeking. Individual scores on changes in anxiety, depression, and stress were generated by 6-item, 4-item, and 3-item questions. A multivariate regression model was fitted in each survey, separately and combined.Results:A total of 6959 residents participated in the study, with 32.78% male and 67.22% female, people living in Wuhan and other cities in Hubei Province accounted for 25.22% and 18.85%, respectively. One week after the Wuhan shutdown, their anxiety, depression, and stress had all increased. Compared with the first survey, the changes in the scores of anxiety, depression, and stress in the second survey were decreased (β = −1.220, −0.798, and −0.623, all P < 0.001). The level of attention, risk of infection, and self-perceived health status tended to be positively associated with the changes in the scores of anxiety, depression, and stress.Conclusions:The study showed that the lives and psychological conditions of residents had undergone negative changes after the Wuhan shutdown, but the measures taken during this period were effective. These results may provide guidance for public health policies in other countries and regions.

Gastrointestinal bleeding (GIB) accounts for a significant proportion of life-threatening bleeding cases occurring after allogeneic haematopoietic stem cell transplantation (allo-HSCT). However, data on GIB after haploidentical HSCT (haplo-HSCT) are not available. A total of 3180 patients received haplo-HSCT at Peking University People’s Hospital from January 2015 to November 2019, and GIB occurred in 188 of these patients (incidence of 5.9%). Platelet counts

We performed a nested case-control study to investigate the incidence, treatment, and prognosis of central nervous system (CNS) relapse after allogenic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia (AML) and compared the outcomes of patients with CNS relapse following haploidentical donor (HID) HSCT versus identical sibling donor (ISD) HSCT. A total of 37 patients (HID-HSCT, 24; ISD-HSCT, 13) developed CNS relapse after transplantation between January 2009 and January 2019, with an incidence of 1.81%. The median time from transplantation to CNS relapse was 239 days. Pre-HSCT CNS involvement (HR 6.940, 95% CI 3.146–15.306, p

Background: To detect the serum procalcitonin (PCT) levels of peritoneal dialysis (PD) patients. Methods: We analyzed the relationship between the PCT Level and dialysis adequacy. We studied 120 peritoneal dialysis patients without signs of infection in Affiliated Hangzhou First People's Hospital and 120 controls from Jan 2014 to Apr 2016. PCT and high sensitivity C-reactive protein (hs-CRP) were detected. 120 PD patients were divided into two groups according to the dialysis adequacy. A correlation analysis was processed between the PCT level and the total solute clearance (Kt/V). The value of PCT for identifying the dialysis adequacy in PD patients was assessed by ROC curve analysis. Results: PCT level in serum of PD group (0.29±0.24 ng/ml) was higher than that of the control group (0.02±0.01 ng/ml) (P

Purpose The delineation of the clinical target volume (CTV) is a crucial, laborious and subjective step in cervical cancer radiotherapy. The aim of this study was to propose and evaluate a novel end-to-end convolutional neural network (CNN) for fully automatic and accurate CTV in cervical cancer. Methods A total of 237 computed tomography (CT) scans of patients with locally advanced cervical cancer were collected and evaluated. A novel 2.5D CNN network, called DpnUNet, was developed for CTV delineation and further applied for CTV and organ-at-risk (OAR) delineation simultaneously. Comprehensive comparisons and experiments were performed. The mean Dice similarity coefficient (DSC), 95th percentile Hausdorff distance (95HD) and subjective evaluation were used to assess the performance of this method. Results The mean DSC and 95HD values were 0.86 and 5.34 mm for the delineated CTVs. The clinical experts’ subjective assessments showed that 90% of the predicted contours were acceptable for clinical usage. The mean DSC and 95HD values were 0.91 and 4.05 mm for bladder, 0.85 and 2.16 mm for bone marrow, 0.90 and 1.27 mm for left femoral head, 0.90 and 1.51 mm for right femoral head, 0.82 and 4.29 mm for rectum, 0.85 and 4.35 mm for bowel bag, 0.82 and 4.96 mm for spinal cord respectively. The average delineation time for one patient’s CT images was within 15 seconds. Conclusion The experimental results demonstrate that the CTV and OARs delineated for cervical cancer by DpnUNet was in close agreement with the ground truth. DpnUNet could significantly reduce the radiation oncologists’ contouring time.

The challenge for surgical management of a pancreatic pseudocyst during esophagectomy is not only to preserve the gastric wall, but also to avoid forming a pancreatic fistula. We report a case of a 54-year-old man with an esophageal squamous cell carcinoma who had a synchronous pancreatic pseudocyst. Roux-en-Y cystojejunostomy was performed during a McKeown esophagectomy to enable drainage of the pancreatic pseudocyst through the jejunum. The patient recovered after the operation, and the formation of a pancreatic fistula was avoided successfully.

SUMMARY Congenital heart disease (CHD) is one of the most common combined malformations of microtia. There is currently no specific study that investigates the relationship between microtia and CHD. METHODS This study collected microtia inpatients admitted from May 1, 2015 to July 31, 2016. The diagnosis of CHD was based on patient's symptoms, past history, and echocardiography. Pearson χ2 test was used to analyze the correlation between CHD and microtia. RESULTS A total of 30 cases (3.35%) were documented with CHD, including atrial septal defect (12/40.00%), ventricular septal defect (7/23.30%), patent ductus arteriosus (2/6.70%), complex congenital heart disease (3/10.00%), combined CHD (2/6.70%) and other malformations (4/13.30%). Analysis showed no statistically significant relation between CHD and the side of affected ear or gender. CONCLUSIONS The occurrence of CHD in microtia patients was higher than that in the general population. The relationship between them was explored mainly from the etiological perspective. Microtia and CHD were often combined in syndromes such as Goldenhar syndrome, 22q11 deletion syndrome, and CHARGE syndrome. Absence of genes or abnormal embryo development associated with these syndromes leads to the occurrence of both.

Lung cancer is one of the common types of malignant disorders and the most prevalent cause of cancer-related mortality in the world. Although a wide range of approaches has been examined, strategies in prevention and treatment of lung cancer are still inadequate. Studies show that Vitamin D (VitD) is involved in various biological pathways and has been associated with the etiopathogenesis of several diseases, like cancers. In Vitro and In Vivo experiments have disclosed that VitD plays immunomodulatory and anti-tumor functions. Several lines of evidence have indicated that VitD is involved in the inflammatory settings of the lung. Epidemiological studies have reported that sufficient levels of VitD might be critical in the prevention of lung cancer. Polymorphisms in the genes encoding the different molecules involved in the signaling of VitD might affect the lung cancer risk as well as the quality and quantity of responses to different treatments. In this review article, we intended to clarify the implications of VitD in the normal biology and physiology of the lung and discuss diverse line of evidence about the possible role of VitD in the prevention or treatment of lung cancer.

Background Rosacea is recognized as a chronic inflammatory cutaneous disorder associated with multiple systemic illnesses. However, the association between rosacea and cardiometabolic disease (CMD) remains controversial. Objective To evaluate the association between rosacea and CMD by a systematic review and meta-analysis. Methods A comprehensive search of studies published before October 16, 2019, was performed in databases of PubMed, Embase, Cochrane Library, and Web of Science. The pooled risk ratios or standardized mean differences were calculated. Results Thirteen studies were included, representing 50,442 patients with rosacea. Patients with rosacea had higher prevalence of dyslipidemia, higher prevalence of hypertension, higher total cholesterol, higher low-density lipoprotein, higher triglycerides, higher systolic blood pressure, higher diastolic blood pressure, and higher fasting blood glucose. Rosacea was not associated with ischemic heart disease, stroke, diabetes, and high-density lipoprotein. Limitations No subgroup analysis could be performed according to the subtypes and severity of rosacea. Conclusions Rosacea showed a correlation with hypertension and dyslipidemia but not with ischemic heart disease, stroke, or diabetes. We advocate screening for CMD indicators among patients with rosacea, which may be helpful for diagnosis and appropriate treatment at an early stage of disease.
