    Abstract Introduction: Depression and anxiety are common mental health disorders among adolescents and negatively impact their physical and mental health. Depression and anxiety also exert a tremendous economic burden to society. But in China, there is no systematic review to state the exact prevalence of adolescent depression and anxiety; there is also a lack of systematic reviews of factors that influence depression and anxiety. Hence, in this systematic review, we aim to summarise the current evidence of the prevalence of and factors influencing depression and anxiety among Chinese adolescents.
    Methods and analysis: This protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. We will comprehensively search four English databases (PubMed, Web of Science, CINAHL in EBSCO interface, PsycINFO in ProQuest interface) and three Chinese databases (China National Knowledge Infrastructure, WanFang and SinoMed) for studies from inception to 31 August 2022. Screening for eligible studies and data extraction will be conducted by two reviewers independently, and all discrepancies will be resolved through group discussion.
    Ethics and dissemination: Because this is a review of published studies, no ethical approval is required. The results will be reported in a peer-reviewed journal or disseminated at relevant conferences.

    Abstract Intimate partner violence (IPV) is a major public health problem resulting in a significant impediment to equal participation, quality of life, and personal, social, and economic development. At present, a variety of screening instruments for IPV have emerged in developed countries, and some of them have been adapted to the language and culture of different countries, such as Hurt, Insult, Threaten, Scream (HITS) and the Abuse Assessment Screen (AAS). The selection of the most appropriate IPV screening instrument for the target population and context from among those instruments has become difficult for researchers when intending to start screening. Therefore, a systemic review of IPV screening instruments is needed. This protocol describes a COSMIN-based systematic review of the measurement properties of these instruments. The aims of the systematic review are to (1) evaluate the methodological quality of studies on the measurement properties including the validity, reliability, and internal consistency of these IPV screening instruments, and (2) provide suggestions for relevant researchers in their local context for using the IPV screening instruments.

    Abstract Background: Heated tobacco products (HTPs), including I Quit Ordinary Smoking (IQOS), are new tobacco products that use an electronic device to heat compressed tobacco leaves to generate an aerosol for consumers to inhale. Marketing of HTPs is prevalent on Instagram, a popular social media platform.
    Objective: This study aims to characterize posts related to HTPs on Instagram and their associations with user engagement.
    Methods: Through the Instagram application programming interface, 979 Instagram posts were collected using keywords related to HTPs, such as "IQOS" and "heat-not-burn." Among them, 596 posts were related to IQOS and other HTP marketing. The codebook was developed from a randomly selected 200 posts on the post content by hand coding, which was applied to the remaining 396 Instagram posts. Summary statistics were calculated, and statistical hypothesis testing was conducted to understand the popularity of Instagram posts on HTPs. Negative binomial regression models were applied to identify Instagram post characteristics associated with user engagement (eg, count).
    Results: Among Instagram posts related to HTP marketing (N=596), "product display" was dominant (n=550, 92.28%), followed by "brand promotion" (n=41, 6.88%), and "others" (n=5, 0.84%). Among posts within "product display," "device only" was the most popular (n=338, 61.45%), followed by "heatstick only" (n=80, 14.55%), "accessory" (n=66, 12%), "device and heatstick" (n=56, 10.18%), and "capsule" (n=10, 1.82%). A univariate negative binomial regression model with pairwise comparisons across "product display" types showed that the number of likes for posts with HTP heatsticks was significantly lower compared to posts with HTP devices, accessories, and device-heatstick sets. Multivariate negative binomial regression models showed that HTP-related Instagram posts with a model or lifestyle elements (;=.60, 95% CI 0.36-0.84) or without obvious product advertising information (=.69, 95% CI 0.49-0.89) received more likes.
    Conclusions: It is shown that posts with product displays were dominant among HTP-related posts on Instagram. Posts with model or lifestyle elements are associated with high user engagement, which might be one of the web-based marketing strategies of HTPs.

    Abstract Surgical site infection (SSI) is one of the common postoperative complications after craniotomy for glioblastoma patients. Previous studies have investigated the risk factors for SSI in patients with glioblastoma. Whereas big differences in research results exist, and the correlation coefficients of different research results are quite different. A meta-analysis was conducted to examine the risk factors related to surgical site infection in patients with glioblastoma. We searched English databases to collect case-control studies or cohort studies published before 15 October 2023 including PubMed, Web of Science, Embase. The risk of bias of the included studies was assessed via Newcastle-Ottawa Scale. The analysis was performed using RevMan 5.4.1 tool. A total of 4 articles (n = 2222) were selected in this meta-analysis. The following risk factors were presented to be correlated with SSI in glioblastoma: irradiation (OR = 1.88, 95% CI [0.46, 7.60]), more than 3 surgeries (OR = 2.99, 95% CI [1.47, 6.08]). Occurrence of SSI is influenced by a variety of factors. Thus, we should pay close attention to high-risk subjects and take crucial targeted interventions to lower the SSI risk following craniotomy. Owing to the limited quality and quantity of the included studies, more rigorous studies with adequate sample sizes are needed to verify the conclusion.

    Abstract This study aimed to investigate the risk factors for cervical radiculopathy (CR) along with identifying the relationships between age, cervical flexors, and CR. This was a retrospective cohort study, including 60 patients with CR enrolled between December 2018 and June 2020. In this study, we measured C2 to C7 Cobb angle, disc degeneration, endplate degeneration, and morphology of paraspinal muscles and evaluated the value of predictive methods using receiver operating characteristic curves. Next, we established a diagnostic model for CR using Fisher discriminant model and compared different models by calculating the kappa value. Age and cervical flexor factors were used to construct clinical predictive models, which were further evaluated by C-index, receiver operating characteristic curve, calibration curve, and decision curve analysis. Multivariate analysis showed that age and cervical flexors were potential risk factors for CR, while the diagnostic model indicated that both exerted the best diagnostic effect. The obtained diagnostic equation was as follows: y1 = 0.33 × 1 + 10.302 × 2-24.139; y2 = 0.259 × 1 + 13.605 × 2-32.579. Both the C-index and AUC in the training set reached 0.939. Moreover, the C-index and AUC values in the external validation set reached 0.961. We developed 2 models for predicting CR and also confirmed their validity. Age and cervical flexors were considered potential risk factors for CR. Our noninvasive inspection method could provide clinicians with a more potential diagnostic value to detect CR accurately.

    Abstract Introduction and objective: Constipation is a common complication following spinal surgery that can result in distension, abdominal pain, infection, and even intestinal perforation. This study reports on an evidence-based implementation project to reduce the incidence of constipation in spinal surgery wards.
    Methods: The project was conducted in the spinal surgery ward of a general tertiary hospital in Changsha City, China, from March to August 2022. We used the JBI Implementation Framework and the JBI Model of Evidence-Based Healthcare for audits and feedback. Data were collected and analyzed using JBI's Practical Application of Clinical Evidence System (PACES) software. Seven audit criteria were developed based on the best practice recommendations summarized by JBI. A baseline audit was conducted with 20 nurses and 50 patients in the spinal surgery ward, and a follow-up audit was conducted using the same sample size and setting.
    Results: The baseline audit revealed compliance below 46% for 5 of the 7 criteria. Strategies developed to address poor compliance included educating nurses and patients, developing a postoperative constipation risk assessment sheet, organizing stakeholder focus group meetings, establishing a constipation management routine, and effective empowerment of nurses. The follow-up audit showed positive compliance results, with the highest rate for criterion 7 (100%) and the greatest increase for criterion 2 (from 0% to 78%). Furthermore, the incidence of postoperative constipation decreased from 48% to 16%.
    Conclusion: The project improved compliance with audit criteria, reduced the incidence of constipation, and enhanced the efficiency of quality management in the spinal surgery ward.

    Abstract Iatrogenic laryngotracheal stenosis (iLTS) is a pathological condition characterized by the narrowing of the laryngeal and tracheal structures due to the formation of abnormal scar tissue. The core of iLTS lies in the fibrosis of the laryngotracheal tissue, and recent research has unveiled novel discoveries regarding the underlying mechanisms of fibrosis. This review provides an overview of the recent advancements in understanding the mechanisms of fibrosis in iLTS. It encompasses various aspects, such as immune system dysregulation, changes in the extracellular matrix (ECM), metabolic alterations, and the role of microbial flora. The review also explores the interplay and relationships between these new mechanisms, establishing a theoretical foundation for the development of multi-target therapies and combination therapies for iLTS.

    Abstract Background: With the increasing popularity of snus, it is essential to understand the public perception of this oral tobacco product. Twitter-a popular social media platform that is being used to share personal experiences and opinions-provides an ideal data source for studying the public perception of snus.
    Objective: This study aims to examine public perceptions and discussions of snus on Twitter.
    Methods: Twitter posts (tweets) about snus were collected through the Twitter streaming application programming interface from March 11, 2021, to February 26, 2022. A temporal analysis was conducted to examine the change in number of snus-related tweets over time. A sentiment analysis was conducted to examine the sentiments of snus-related tweets. Topic modeling was applied to tweets to determine popular topics. Finally, a keyword search and hand-coding were used to understand the health symptoms mentioned in snus-related tweets.
    Results: The sentiment analysis showed that the proportion of snus-related tweets with a positive sentiment was significantly higher than the proportion of negative sentiment tweets (4341/11,631, 37.32% vs 3094/11,631, 26.60%; P<.001). The topic modeling analysis revealed that positive tweets focused on snus's harm reduction and snus use being an alternative to smoking, while negative tweets focused on health concerns related to snus. Mouth and respiratory symptoms were the most mentioned health symptoms in snus-related tweets.
    Conclusions: This study examined the public perception of snus and popular snus-related topics discussed on Twitter, thus providing a guide for policy makers with regard to the future formulation and adjustment of tobacco regulation policies.

    Abstract With the rapid development of the offshore oil industry, electric submersible pumps have become more and more important. They are the main pumping equipment in oil well production and have huge advantages in terms of displacement and production costs. Due to the complex structure of the electric submersible pump, the bad working environment will cause failures. The failure of tubing string leakage is a common failure in oilfields; tubing string leakage of the electric submersible pump will reduce oil production. In order to reduce the economic loss of oil well production. This paper uses PCA and Mahalanobis distance to make the tubing Fault diagnosis of leakage. The feasibility of the algorithm is verified through experiments. The result shows that it can diagnose the failure time of pipe string leakage in advance and hence help us to reduce the maintenance cost of offshore oilfields.
