ABSTRACT
In this article, a visual security image encryption algorithm based on compressed sensing is proposed. The algorithm consists of two stages: the compression and encryption stage and the embedding stage. The key streams in the compression and encryption stage are generated by a newly constructed four-dimensional discrete chaotic map, while the Gaussian measurement matrix is generated by a Chebyshev map, and both of their generations are related to the feature code of the carrier image, which enhances the security of the ciphertext. In the compression and encryption stage, a scrambling-cyclic shift-diffusion encryption structure is adopted for the compressed image in which the shift number in the cyclic shift stage and the diffusion key streams are dynamically changed according to each pixel value, so the algorithm can resist chosen plaintext attack. In the embedding stage, the carrier image is first subjected to integer wavelet transform to obtain the high-frequency and low-frequency components of the image, and then the intermediate ciphertext information is embedded into its high-frequency components. Finally, the carrier image is subjected to inverse integer wavelet transform to obtain a visually secure ciphertext image. The experimental results and security analysis indicate that the encryption scheme has a large key space, high decryption key sensitivity, similar histogram distribution between the carrier image and the visual security ciphertext image, and good robustness to noise attacks.
ABSTRACT
BACKGROUND: Cancer has emerged as a considerable global health concern, contributing substantially to both morbidity and mortality. Recognizing the urgent need to enhance the overall well-being and quality of life (QOL) of cancer patients, a growing number of researchers have started using online mindfulness-based interventions (MBIs) in oncology. However, the effectiveness and optimal implementation methods of these interventions remain unknown. OBJECTIVE: This study evaluates the effectiveness of online MBIs, encompassing both app- and website-based MBIs, for patients with cancer and provides insights into the potential implementation and sustainability of these interventions in real-world settings. METHODS: Searches were conducted across 8 electronic databases, including the Cochrane Library, Web of Science, PubMed, Embase, SinoMed, CINAHL Complete, Scopus, and PsycINFO, until December 30, 2022. Randomized controlled trials involving cancer patients aged ≥18 years and using app- and website-based MBIs compared to standard care were included. Nonrandomized studies, interventions targeting health professionals or caregivers, and studies lacking sufficient data were excluded. Two independent authors screened articles, extracted data using standardized forms, and assessed the risk of bias in the studies using the Cochrane Bias Risk Assessment Tool. Meta-analyses were performed using Review Manager (version 5.4; The Cochrane Collaboration) and the meta package in R (R Foundation for Statistical Computing). Standardized mean differences (SMDs) were used to determine the effects of interventions. The Reach, Effectiveness, Adoption, Implementation, and Maintenance framework was used to assess the potential implementation and sustainability of these interventions in real-world settings. RESULTS: Among 4349 articles screened, 15 (0.34%) were included. The total population comprised 1613 participants, of which 870 (53.9%) were in the experimental conditions and 743 (46.1%) were in the control conditions. The results of the meta-analysis showed that compared with the control group, the QOL (SMD 0.37, 95% CI 0.18-0.57; P<.001), sleep (SMD -0.36, 95% CI -0.71 to -0.01; P=.04), anxiety (SMD -0.48, 95% CI -0.75 to -0.20; P<.001), depression (SMD -0.36, 95% CI -0.61 to -0.11; P=.005), distress (SMD -0.50, 95% CI -0.75 to -0.26; P<.001), and perceived stress (SMD -0.89, 95% CI -1.33 to -0.45; P=.003) of the app- and website-based MBIs group in patients with cancer was significantly alleviated after the intervention. However, no significant differences were found in the fear of cancer recurrence (SMD -0.30, 95% CI -1.04 to 0.44; P=.39) and posttraumatic growth (SMD 0.08, 95% CI -0.26 to 0.42; P=.66). Most interventions were multicomponent, website-based health self-management programs, widely used by international and multilingual patients with cancer. CONCLUSIONS: App- and website-based MBIs show promise for improving mental health and QOL outcomes in patients with cancer, and further research is needed to optimize and customize these interventions for individual physical and mental symptoms.

BACKGROUND: This study aimed to explore the prognostic role of pan-immune-inflammation value (PIV) and develop a new risk model to guide individualized adjuvant systemic treatment following radiofrequency ablation (RFA) for early-stage hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Patients with early-stage HCC treated by RFA were randomly divided into training cohort A (n = 65) and testing cohort B (n = 68). Another 265 counterparts were enrolled into external validating cohort C. Various immune-inflammatory biomarkers (IIBs) were screened in cohort A. Prognostic role of PIV was evaluated and validated in cohort B and C, respectively. A nomogram risk model was built in cohort C and validated in pooled cohort D. Clinical benefits of adjuvant anti-angiogenesis therapy plus immune checkpoint inhibitor (AA-ICI) following RFA was assessed in low- and high-risk groups. RESULTS: The cutoff point of PIV was 120. High PIV was an independent predictor of unfavorable recurrence-free survival (RFS) and overall survival (OS). RFS and OS rates of patients with high PIV were significantly lower than those with low PIV both in cohort B (PRFS=0.016, POS=0.011) and C (PRFS<0.001, POS<0.001). The nomogram model based on PIV, tumor number and BCLC staging performed well in risk stratification in external validating cohort C. Adjuvant AA-ICI treatment showed an added benefit in OS (p = 0.011) for high-risk patients. CONCLUSIONS: PIV is a feasible independent prognostic factor for RFS and OS in early-stage HCC patients who received curative RFA. The proposed PIV-based nomogram risk model could help clinicians identify high-risk patients and tailor adjuvant systemic treatment and disease follow-up scheme.
Key findingsHigh pan-immune-inflammation value (PIV) is an independent indicator of unfavorable recurrence-free survival (RFS) and overall survival (OS) for early-stage hepatocellular carcinoma (HCC) patients who received curative radiofrequency ablation (RFA).Adjuvant anti-angiogenesis target therapy plus immune checkpoint inhibitor (AA-ICI) treatment showed added benefit in OS for the high-risk patients defined by a nomogram risk model based on PIV, tumor number and BCLC staging.What is known and what is new?Inflammation and impaired host immunity are associated with carcinogenesis and progression of HCC. Increasing evidences showed that immune-inflammatory biomarkers (IIBs) had prognostic roles in early-stage HCC patients who received RFA. However, prognostic potential of PIV has not been determined in this setting.Herein, high PIV was first reported to be an independent risk factor of poor RFS and OS in early-stage HCC patients treated by curative RFA and helped to discriminate patients between low- and high-risk groups. Adjuvant AA-ICI treatment following RFA was beneficial to OS of patients in the high-risk group.What is the implication, and what should change now?For early-stage HCC with high-risk factors (high PIV, multiple tumor foci and more advanced BCLC stage), intensive follow-up and adjuvant systemic therapy following curative RFA were warranted.

Purpose: The purpose of the present study is to examine the factors contributing to the development of eating behavior in overweight and obese children from the perspective of the family system. Methods: A cross-sectional survey was conducted by using convenience sampling method to select 388 participants in two primary schools in Jiangsu, China. Individual, family and social-related factors were collected. Individual factors included age, gender, ethnicity, single child, social anxiety, depression, physical activity, sleep duration, screen time. Family factors included family environment, family structure, family function, family income, parenting style, parental feeding behavior, home food environment and marital satisfaction. Social-related factors included place of residence, number of surrounding restaurants and social support. Univariate analysis, correlation analysis and multivariate analysis were used to identify factors of eating behavior among Chinese children with overweight and obese. Results: In this study, 388 participants took part with a 94.865% response rate. In the univariate analysis, the significant differences regarding Dutch Eating Behavior Questionnaire (DEBQ) scores were found between children aged 6-9 years and those aged >9 years. Correlation analysis indicated that parent's nutrition literacy (r = 0.118, P < 0.05), pressure to eat (r = 0.212, P < 0.01), perception of child weight (r = -0.112, P < 0.05) and family function (r = -0.563, P < 0.01) were associated with children's eating behavior. With regard to psychosocial factors, children's social anxiety (r = 0.299, P < 0.01) and depressive symptoms (r = 0.081, P < 0.05) were in positive correlation with eating behavior. The independent variables included in the initial model were age, father's employment status, social anxiety, maternal punishment and harshness, parents' nutrition literacy, pressure to eat, family function and perception of child weight. These variables in the final model accounted for 20.7% of the variance. Conclusion: We found that age, father's employment status, social anxiety, maternal punishment and harshness, parents' nutrition literacy, pressure to eat, family function and perception of child weight have great effect on children's eating behavior who are overweight or obese. As early childhood is a critical timeline for child development, children's social anxiety, parenting style, parent's nutrition literacy, parent's feeding behavior and family function should be intervened to promote eating behavior. Intervention programs aimed at promoting healthy eating behaviors among children, thereby mitigating the risk of pediatric obesity, should primarily target parents.
ABSTRACT
BACKGROUND: Frailty is very common among older people with gastric cancer and seriously affects their prognosis. The development of frailty is continuous and dynamic, increasing the difficulty and burden of care. OBJECTIVES: The aims of this study were to delineate the developmental trajectory of frailty in older people with gastric cancer 1â¯year after surgery, identify heterogeneous frailty trajectories, and further explore their predictors to construct a nomogram for prediction. DESIGN: We conducted a prospective longitudinal observation study. Clinical evaluation and data collection were performed at discharge, and at 1, 3, 6, and 12â¯months. SETTING AND PARTICIPANTS: This study was conducted in a tertiary hospital and 381 gastric cancer patients over 60â¯years who underwent radical gastrectomy completed the 1-year follow-up. METHODS: A growth mixture model (GMM) was used to delineate the frailty trajectories, and identify heterogeneous trajectories. A regression model was performed to determine their predictors and further construct a nomogram based on the predictors. Bootstrap with 1000 resamples was used for internal validation of nomogram, a receiver operating characteristic (ROC) curve to evaluate discrimination, calibration curves to evaluate calibration and decision curve analysis (DCA) to evaluate the clinical value. RESULTS: GMM identified three classes of frailty trajectories: "frailty improving", "frailty persisting" and "frailty deteriorating". The latter two were referred to as heterogeneous frailty trajectories. Regression analysis showed 8 independent predictors of heterogeneous frailty trajectories and a nomogram was constructed based on these predictors. The area under ROC curve (AUC) of the nomogram was 0.731 (95â¯% CIâ¯=â¯0.679-0.781), the calibration curves demonstrated that probabilities predicted by the nomogram agreed well with the actual observation with a mean absolute error of 0.025, and the DCA of nomogram indicated that the net benefits were higher than that of the other eight single factors. CONCLUSIONS: Older gastric cancer patients have heterogeneous frailty trajectories of poor prognosis during one-year postoperative survival. Therefore, early assessment to predict the occurrence of heterogeneous frailty trajectories is essential to improve the outcomes of elderly gastric cancer patients. Scientific and effective frailty interventions should be further explored in the future to improve the prognosis of older gastric cancer patients. CONTRIBUTION OF THE PAPER STATEMENTS: This study constructed a static and dynamic online nomogram with good discrimination and calibration, which can help to screen high-risk patients, implement preoperative risk stratification easily and promote the rational allocation of medical resources greatly. REGISTRATION: ClinicalTrials.gov (Number: NCT05982899). TWEETABLE ABSTRACT: Our findings identified three frailty trajectories and constructed a nomogram to implement preoperative risk stratification and improve patient outcomes.

BACKGROUND: Frailty is commom among gastric cancer survivors and increases the burden of care. AIMS: Our aims were to identify the frailty trajectories and investigate their associations with health outcomes in older gastric cancer survivors. METHODS: We finally recruited 381 patients aged â§60 who underwent radical gastrectomy and recorded frailty at discharge from the hospital, 1, 3, 6, and 12 months after surgery. Growth mixture modeling was used to investigate the frailty trajectories and linear regression models were used to examine their associations with health outcomes. RESULTS: Three classes of frailty trajectories were identified: the "improving frailty", "maintaining frailty" and "deteriorating frailty". Compared with class 1, patients who followed class 2 and class 3 frailty trajectories were more likely to have more severe disability (ß = -14.22, 95 % CI: -17.92, -10.61, P < 0.001; ß = -48.34, 95 % CI: -52.25, -44.42, P < 0.001), worse quality of life (ß = 10.89, 95 % CI: 7.71,14.08, P < 0.001; ß = 34.82, 95 % CI: 31.46, 38.19, P < 0.001), and more frequency readmission within 1 year (ß = 1.02, 95 % CI: 0.98, 1.06, P < 0.001; ß = 2.10, 95 % CI: 2.01, 2.14, P < 0.001) after controlling potential confounders. However, class 2 and class 3 have no significant difference from class 1 in the total hospitalization costs (ß = 1672.12, 95 % CI: -7145.95, 10496.19, P = 0.709; ß = 7651.60, 95 % CI: -1670.28, 16793.47, P = 0.107). CONCLUSIONS: Our study suggested the significant prognostic heterogeneity in frailty trajectories, and what we need to do is to identify patients with heterogeneous trajectory and intervene in them to reduce adverse outcomes, promote rational use of resources, and reduce the burden of care.

BACKGROUND: Hospice and Palliative Care (HPC) is in high demand in China; however, the country is facing the shortage of qualified HPC nurses. A well-suited competence framework is needed to promote HPC human resource development. Nevertheless, existing unstandardized single-structured frameworks may not be sufficient to meet this need. This study aimed at constructing a comprehensive multi-structured HPC competence framework for nurses. METHODS: This study employed a mixed-method approach, including a systematic review and qualitative interview for HPC competence profile extraction, a two-round Delphi survey to determine the competences for the framework, and a cross-sectional study for framework structure exploration. The competence profiles were extracted from publications from academic databases and interviews recruiting nurses working in the HPC field. The research team synthesized profiles and transferred them to competences utilizing existing competence dictionaries. These synthesized competences were then subjected to Delphi expert panels to determine the framework elements. The study analyzed theoretical structure of the framework through exploratory factor analysis (EFA) based on a cross-sectional study receiving 491 valid questionnaires. RESULTS: The systematic review involved 30 publications from 10 countries between 1995 and 2021, while 13 nurses from three hospitals were interviewed. In total, 87 and 48 competence profiles were respectively extracted from systematic review and interview and later synthesized into 32 competences. After the Delphi survey, 25 competences were incorporated into the HPC competence framework for nurses. The EFA found a two-factor structure, with factor 1 comprising 18 competences namely Basic Competences; factor 2 concluding 7 competences namely Developmental Competences. CONCLUSIONS: The two-factor HPC competence framework provided valuable insights into the need and directions of Chinese HPC nurses' development.

Background: Rates of overweight and obesity continue to grow in adolescents. Overweight and obesity in adolescence are associated with numerous immediate and long-term adverse health conditions. Throughout adolescence, parents and the family have an important and central influence on adolescents' health and lifestyle. The home environment may be a major factor in shaping children's weight. However, our current understanding of the interplay between family-related variables in adolescents with overweight or obesity is limited and fragmented. This study aimed to assess the relationship between family-related variables in adolescents who are overweight or obese using network analysis and inform future health promotion for family-based intervention. Methods: Participants (n = 488) were recruited from middle schools in Nanjing from October 2022 to March 2023. Participants, together with their parents, completed a questionnaire at school about the family food environment, family size, family APGAR index, family physical activity facilities, parental mental health, rearing behavior, parental weight status, drinking history, marital satisfaction, and sociodemographic characteristics. Results: The network split into three distinct communities of items. Network analysis showed that parental mental health and paternal rearing styles-rejection were the most central nodes in the network. In contrast, maternal weight status was the most peripheral and least connected nodes. Conclusion: Family-related variables constituted a connected network in adolescents with overweight or obesity. The pattern of network node connections supports that interventions could prioritize targeting changing parental mental health and paternal rearing styles in adolescents with overweight or obesity.
ABSTRACT
OBJECTIVES: To explore the reflections and experiences of nurses who were deployed to the frontline to combat COVID-19 in Wuhan, China. In order to gain insights that can be useful in developing cultivating positive professional values and attitudes towards future public health emergencies. DESIGN: Qualitative study using semistructured interviews. Data were transcribed and analysed using the Colaizzi's 7-step method. The study is reported in accordance with the consolidated Standards for Reporting Qualitative Research. SETTING: Telephonic interviews with nine participants who were deployed from Nanjing to Hubei Province for the fight against COVID-19. PARTICIPANTS: Of 11 volunteer nurses deployed to Hubei Province for the fight against COVID-19, two nurses did not finish the interview because of their working hours. The remaining nine were recruited through purposive sampling using the following criteria: nurses who were deployed at the first stage and those who verbally agreed and signed an informed consent form to participate in the study. RESULTS: Three thematic categories and subthemes that were identified from the analysis were as follows: (1) 'Assertive attitude to fight against the pandemic', included three subthemes: 'Inner calling towards professional accountability for saving lives', 'Extrinsic support that facilitates the commitment to the nursing profession' and 'Holistic value ascribed to the nursing profession'. (2) 'Challenges associated with the anti-pandemic mission', included 'overcoming challenges around the strict requirements for personal protection' and 'Fear and uncertainty over the rapid progression of the disease'. (3) 'Unbearable heaviness and lightness of being a nurse', with two subthemes: 'the heavy crown of the anti-pandemic hero' and 'eternal reverence without regrets'. CONCLUSIONS: As reflected by the nurses on frontline combating COVID-19, it was necessary to inculcate professional nursing values in them, as only their dedication and selflessness could improve humanity's chances against the disease.

INTRODUCTION: This study aimed to explore the associations of low hand grip strength (HGS), HGS asymmetry, their combinations, and frailty on hospital readmissions, total complications, and prolonged length of stay (PLOS) among older adults with gastric cancer. MATERIALS AND METHODS: This study included 342 patients with gastric cancer aged ≥60 years who were scheduled to undergo radical surgery. The Tilburg Frailty Indicator (TFI) was used to collect information on frailty. HGS was measured twice for each hand using an electronic handgrip dynamometer. The highest HGS readings on each hand were used for calculating the HGS asymmetry ratio: non-dominant HGS (kg)/dominant HGS (kg). The Fine and Gray proportional subdistribution hazard model and the logistic regression model were used for the analyses, with covariates adjusted. RESULTS: Low HGS (subdistribution hazard ratios [SHR] = 2.10, 95% confidence interval [CI] = 1.05-3.93, P = 0.036) and low HGS with HGS asymmetry (SHR = 3.95, 95% CI = 1.50-10.36, P = 0.005) were significantly associated with hospital readmissions. Frailty was associated with total complications (odds ratio [OR] = 2.87, 95% CI = 1.61-5.13, P < 0.001) and PLOS (OR = 1.98, 95% CI = 1.19-3.29, P < 0.001). Low HGS, HGS asymmetry, and their combinations were not significantly associated with total complications and PLOS. DISCUSSION: Preoperative low HGS and low HGS with HGS asymmetry were associated with hospital readmissions, while frailty was associated with total complications and PLOS among older adults with gastric cancer. In the future, more rigorously designed studies are needed to verify our results further to improve preoperative clinical assessment and frailty evaluation among older adults with gastric cancer.

PURPOSE: Frailty is defined as a state of decreased physiologic reserves arising from cumulative deficits in multiple homeostatic systems, which is important in the field of clinical oncology. We aimed to explore the relationship between preoperative frailty and adverse outcomes, and systematically analyze the factors influencing frailty based on the health ecology model among elderly gastric cancer patients. METHODS: A observational study was conducted to select 406 elderly patients who would undergo gastric cancer surgery at a tertiary hospital. The logistic regression model was used to examine the relationship between preoperative frailty and adverse outcomes, including total complications, prolonged length of stay (PLOS), and 90-day hospital readmission. Based on the health ecology model, the factors which may influence frailty were collected from four levels. Univariate and multivariate analysis were utilized to determine the factors influencing preoperative frailty. RESULTS: Preoperative frailty was associated with total complications (odds ratio [OR] 2.776, 95% confidence interval [CI] 1.588-4.852), PLOS (OR 2.338, 95%CI 1.342-4.073), and 90-day hospital readmission (OR 2.640, 95% CI 1.275-5.469). Besides, nutritional risk (OR 4.759, 95% CI 2.409-9.403), anemia (OR 3.160, 95% CI 1.751-5.701), number of comorbidity ≥ 2 (OR 2.318, 95% CI 1.253-4.291), low physical activity level (OR 3.069, 95% CI 1.164-8.092), apathetic attachment (OR 2.656, 95% CI 1.457-4.839), personal monthly income ≤ 1000 yuan (OR 2.033, 95% CI 1.137-3.635) and anxiety (OR 2.574, 95% CI 1.311-5.053) were independent risk factors for frailty. High physical activity level (OR 0.413, 95% CI 0.208-0.820) and improved objective support (OR 0.818, 95% CI 0.683-0.978) were independent protective factors for frailty. CONCLUSIONS: Preoperative frailty was associated with multiple adverse outcomes and could be affected by factors of different dimensions from the health ecology perspective, including nutrition, anemia, comorbidity, physical activity, attachment style, objective support, anxiety, and income, which can guide the formation of a comprehensive prehabilitation for frailty among elderly gastric cancer patients.

An image encryption algorithm for the double scrambling of the pixel position and bit was cryptanalyzed. In the original image encryption algorithm, the positions of pixels were shuffled totally with the chaotic sequence. Then, the 0 and 1-bit positions of image pixels were scrambled through the use of another chaotic sequence generated by the input key. The authors claimed that the algorithm was able to resist the chosen-plaintext attack. However, through the analysis of the encryption algorithm, it was found that the equivalent key of the whole encryption algorithm was the scrambling sequence T in the global scrambling stage, the pixel bit level scrambling sequence WT and the diffusion sequence S. The generation of scrambling sequence T is related to the sum of all pixel values of the plaintext image, while the generation of WT and S is not associated with the image to be encrypted. By using a chosen-plaintext attack, these equivalent key streams can be cracked so as to realize the decoding of the original chaotic encryption algorithm. Both theoretical analysis and experimental results verify the feasibility of the chosen-plaintext attack strategy. Finally, an improved algorithm was proposed to overcome the defect, which can resist the chosen-plaintext attack and has the encryption effect of a "one time pad".
ABSTRACT
AIM: Nutritional status and frailty are significant indicators reflecting physiological reserve. We sought to establish and validate a web-based calculator containing the Geriatric Nutritional Risk Index (GNRI) and the Tilburg Frailty Indicator (TFI) together with general clinical information to predict total complications among elderly patients with gastric cancer. METHODS: This was a prospective cohort study of 582 elderly patients with gastric cancer in a tertiary hospital in China. Nutritional status and frailty were assessed by the GNRI and the TFI, respectively. The nomogram was built and further converted into a web-based calculator. The receiver operating characteristic analysis was performed to evaluate the discrimination of the nomogram. Calibration was assessed using the calibration curve and Hosmer-Lemeshow test via the bootstrap resampling procedure. The decision curve analyses (DCAs) were employed to quantify the net benefits of a certain threshold probability for assessing the clinical values. RESULTS: The GNRI (odds ratio [OR], 0.921; 95% confidence interval [CI], 0.895-0.949; P < 0.001), the TFI (OR, 1.243; 95% CI, 1.113-1.386; P < 0.001), surgical approach (OR, 1.913; 95% CI, 1.073-3.408; P = 0.028) and comorbidity (OR = 1.599, 95%CI = 1.028-2.486, P = 0.037) were independently associated with total complications. The nomogram demonstrated good discrimination (area under the receiver operating characteristic curve: training cohort, 0.735; validation cohort, 0.777) and calibration (P = 0.135). The DCA curves of the nomogram also showed good positive net benefits. CONCLUSIONS: The web-based calculator incorporating the GNRI, the TFI, surgical approach, and comorbidity could successfully predict total complications among elderly patients with gastric cancer with good accuracy in a convenient manner.

Oro-maxillo-facial metastasis from hepatocellular carcinoma (HCC) is very rare, and reports on treating maxillary metastasis from HCC are unavailable. Anti-angiogenesis therapy combined with immunotherapy represented by programmed cell death 1 (PD-1) or its ligand (PD-L1) inhibitor has become the standard treatment of advanced HCC. However, integrating chemoradiotherapy into immunotherapy-bevacizumab combination therapy has not been reported. Here, we presented a Chinese woman with maxillary metastasis from HCC who achieved a nearly complete response (CR) to a quadruple treatment scheme consisting of a PD-1 monoclonal antibody (sintilimab), bevacizumab biosimilar IBI305, hypo-fractionated intensity-modulated radiotherapy (hfIMRT), and concurrent oxaliplatin. This comprehensive treatment is an innovative and effective therapy for advanced HCC.
ABSTRACT
PURPOSE: This systematic review and meta-analys is aimed to explore the effects of prehabilitation on postoperative outcomes in frail cancer patients. METHODS: A comprehensive literature search was conducted using PubMed, Cochrane Library, Embase, Web of Science, CINAHL Complete, and other databases from database inception to 15 March 2022. Studies were included if they consisted of a prehabilitation intervention in frail cancer patients undergoing elective surgery. RESULTS: A total of 9 studies encompassing 1313 patients were included in the review. Through meta-analysis, prehabilitation has a positive impact on total complications (RR = 0.83, 95% CI = 0.73 to 0.94, P = 0.004), severe complications (RR = 0.62, 95% CI = 0.43 to 0.90, P = 0.01), and the average length of hospital stay (MD = - 1.36, 95% CI = - 2.38 to - 0.35, P = 0.008). But it had no differences in 30-day and 3-month mortality and 30-day and 3-month readmission rates. Through qualitative synthesis, two studies found that prehabilitation had a favorable tendency to promote functional recovery compared with the control group. CONCLUSION: Prehabilitation had a positive effect on postoperative complications and the average length of hospital stay in frail cancer patients. A personalized and supervised multimodal prehabilitation program with exercise at its core may be more beneficial for them. More studies with extensive follow-up are needed to confirm and update the findings of these results.

BACKGROUND: Frailty represents a progressive deterioration in multi-system of the body and could increase vulnerability to stressors. Recently, several studies found that metabolic syndrome was significantly associated with frailty and emphasized its role in assessing and preventing frailty. However, these conclusions are controversial. We conducted this systematic review and meta-analysis to evaluate the association between metabolic syndrome and frailty. METHODS: Databases including Pubmed, Embase, Web of Science, CINAHL Complete, China National Knowledge Infrastructure (CNKI) and Wanfang Data Knowledge Service Platform were searched for studies on the association between metabolic syndrome and frailty, from inception to 17th June 2022. Two researchers independently screened the literature, extracted the data and evaluated the quality. Stata/SE 15.0 software was used to perform the statistical analysis. RESULTS: Eleven studies were included in this review and eight studies were included in the meta-analysis, involving one prospective cohort studies and ten cross-sectional studies with 12,640 participants. The pooled results indicated that metabolic syndrome was significantly associated with frailty (OR = 1.82, 95% CI = 1.46-2.27) with a low heterogeneity (I2 = 32.1%), and there were significant associations between MetS and weakness (OR = 1.35, 95% CI = 1.15-1.58, I2 = 0.0%), slow gait speed (OR = 1.80, 95% CI = 1.51-2.14, I2 = 93.4%), weight loss (OR = 1.77, 95% CI = 1.36-2.29, I2 = 0.0%) and decreased physical activity (OR = 1.87, 95% CI = 1.49-2.35, I2 = 39.7%). CONCLUSIONS: The findings of this systematic review and meta-analysis suggested that metabolic syndrome could be significantly associated with the presence of frailly. Future studies need to further consider the effects of measurement tools, age and specific disease status in this association. Furthermore, the casual relationship between them is to be determined.

PURPOSE: To explore main determinants of dietary adherence among Chinese patients after bariatric surgery based on the Attitude-Social influence-Efficacy (ASE) model. METHODS: A cross-sectional survey was conducted by using convenience sampling method to select 288 participants in a tertiary hospital in Jiangsu, China. General information and disease-related information were collected as well as applying the Dietary Adherence Scale after Bariatric Surgery (DASBS) and Attitude-Social influence-Efficacy Questionnaire after Bariatric Surgery (ASEQBS). Univariate analysis, correlation analysis, and multivariate analysis were used to identify determinants of dietary adherence among patients after bariatric surgery. RESULTS: A total of 288 questionnaires were effectively collected. The mean DASBS score was 54.90 ± 10.08 among post-bariatric patients. Univariate analysis results showed that education level, time since surgery, smoking, exercise, participation in peer support groups, and participation in nutrition counseling had significant effects on postoperative diet adherence level of patients (P < 0.05). The correlation analysis results showed that the total score of dietary adherence was positively correlated with the total score of intention, attitude, social influence, and self-efficacy, and the correlation coefficients were 0.511, 0.550, 0.460, and 0.484, respectively (P < 0.05). The results of multiple linear regression analysis showed that time since surgery, attitude, intention, social influence, exercise, and self-efficacy entered the regression equation (P < 0.05). The standardized regression coefficients of attitude and intention are 0.237 and 0.196, respectively. The regression model could explain 44.0% of the total variation. CONCLUSION: The dietary adherence of Chinese post-bariatric patients is at an upper-middle level, which needs to be further improved. Time since surgery, exercise, intention, attitude, social influence, and self-efficacy had significant effects on patients' dietary adherence. Attitude had the greatest effect on dietary adherence, followed by intention. The results shed light on that these factors should be emphasized to take personalized intervention strategy in designing dietary intervention program, in order to improve the patient's dietary adherence and surgical outcomes.

Background: Gastrointestinal cancers are the most common malignant tumors worldwide. As the improvement of survival by surgical resection alone for cancers is close to the bottleneck, recent neoadjuvant therapy has been emphasized and applied in the treatment. Despite the advantage on improving the prognosis, some studies have reported neoadjuvant therapy could reduce skeletal muscle and therefore affect postoperative outcomes. However, the conclusions are still controversial. Methods: PubMed, CINAHL, Embase, and Cochrane Library were searched from inception to September 2, 2021. The inclusion criteria were observational studies, published in English, of individuals aged ≥18 years who underwent neoadjuvant therapy with gastrointestinal cancers and were assessed skeletal muscle mass before and after neoadjuvant therapy, with sufficient data on skeletal muscle change or the association with clinical outcomes. Meta-analysis was conducted by using the STATA 12.0 package when more than two studies reported the same outcome. Results: A total of 268 articles were identified, and 19 studies (1,954 patients) were included in the review. The fixed effects model showed that the risk of sarcopenia increased 22% after receiving neoadjuvant therapy (HR=1.22, 95% CI 1.14, 1.31, Z=4.286, P<0.001). In the random effects model, neoadjuvant therapy was associated with skeletal muscle loss, with a standardized mean difference of -0.20 (95% CI -0.31, -0.09, Z=3.49, P<0.001) and a significant heterogeneity (I2 = 62.2%, P<0.001). Multiple meta regression indicated that population, neoadjuvant therapy type, and measuring tool were the potential sources of heterogeneity. The funnel plot revealed that there was no high publication bias in these studies (Begg's test, P=0.544) and the sensitivity analysis showed stable results when separately excluding studies. For the postoperative outcomes, the results revealed that muscle loss during neoadjuvant therapy was significantly related to overall survival (HR=2,08, 95% CI =1.47, 2.95, Z=4.12, P<0.001, I2 = 0.0%), but not related to disease-free survival and other short-term outcomes. Conclusions: This systematic review and meta-analysis revealed that skeletal muscle decreased significantly during neoadjuvant therapy in patients with gastrointestinal cancers and skeletal muscle loss was strongly associated with worse overall survival. More high-quality studies are needed to update and valid these conclusions in a more specific or stratified way.

ABSTRACT
Diabetic nephropathy (DN) is a microvascular disease caused by diabetes. Tanshinone IIA has been indicated to ameliorate streptozotocin-induced DN. This study explores the effect of tanshinone IIA on high glucose-induced renal tubular epithelial cell pyroptosis and inflammation. High glucose-stimulated HK-2 cells were used as the in-vitro model of DN and were treated with tanshinone IIA at concentrations of 1, 5, 10 µM for 24 h with the same doses of tolbutamide as the control. After tanshinone IIA treatment, HK-2 cells were transfected with pcDNA-transforming growth factor beta 1 (TGFB1) or sh-TGFB1 for 48 h. RT-qPCR was used to detect the mRNA levels of TNF-α, IL-6, IL-1ß, and IL-18. Cell apoptosis and pyroptosis were detected by flow cytometry and cell immunofluorescence. Bioinformatics screening predicted that tanshinone IIA might be an effective component of Salvia miltiorrhiza Bunge (Labiatae) for the treatment of DN. Tanshinone IIA exerted a protective effect in the in-vitro model of DN by suppressing inflammation and pyroptosis via the TGFB1-dependent pathway. Tanshinone IIA inhibited high glucose-induced renal tubular epithelial cell inflammation and cell death through pyroptosis by regulating TGFB1, indicating the therapeutic potential of tanshinone IIA for DN treatment.

PURPOSE: This systematic review and meta-analysis aimed to explore the predictive value of preoperative handgrip strength on postoperative outcomes in patients with gastrointestinal tumors. METHODS: Databases including Cochrane Library, Pubmed, Embase, Web of Science, and CINAHL Complete were searched for articles published from the establishment of database until August 7, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the quality. RESULTS: Eight studies were included, involving five prospective and three retrospective cohort studies with 2291 participants. The prevalence of preoperative low handgrip strength ranged from 11.8 to 62.7%. Preoperative low handgrip strength was associated with an increased risk of total complications (OR = 2.23, 95%CI = 1.43-3.50), pneumonia (OR = 5.16, 95%CI = 3.17-8.38), ileus (OR = 2.48, 95%CI = 1.09-5.65), and short-term mortality (OR = 7.28, 95%CI = 1.90-27.92). CONCLUSION: This systematic review and meta-analysis indicated that preoperative HGS had important value to predict certain adverse postoperative outcomes among patients with GI tumors. Low handgrip strength criteria, definition of total complications, and country are the potential sources of heterogeneity, and more research are required to test and update these results.
