RESUMO

Objective: To explore the effect of a video teach-back method on continuous family nursing care of stroke patients. Methods: Stroke patients hospitalized in our hospital between March 2020 and March 2023 who met the inclusion criteria were randomly divided into an intervention group (n = 45), who received routine health education plus video teach-back training of caregivers, and a control group (n = 45), who received routine health education only. The effects on nursing-related variables were compared between the two groups. Results: Total scores representing the caring ability of caregivers in the intervention group increased significantly over time relative to baseline and were higher than those of the control group. Scores representing the care burden of caregivers in the intervention group decreased significantly over time and were lower than those of the control group. Conclusion: The teach-back method combined with video education improves the nursing ability of family caregivers and can improve the self-care ability of stroke patients.

RESUMO

AIM: To provide a systematic overview of diabetes risk prediction models used for prediabetes screening to promote primary prevention of diabetes. METHODS: The Cochrane, PubMed, Embase, Web of Science and China National Knowledge Infrastructure (CNKI) databases were searched for a comprehensive search period of 30 August 30, 2023, and studies involving diabetes prediction models for screening prediabetes risk were included in the search. The Quality Assessment Checklist for Diagnostic Studies (QUADAS-2) tool was used for risk of bias assessment and Stata and R software were used to pool model effect sizes. RESULTS: A total of 29 375 articles were screened, and finally 20 models from 24 studies were included in the systematic review. The most common predictors were age, body mass index, family history of diabetes, history of hypertension, and physical activity. Regarding the indicators of model prediction performance, discrimination and calibration were only reported in 79.2% and 4.2% of studies, respectively, resulting in significant heterogeneity in model prediction results, which may be related to differences between model predictor combinations and lack of important methodological information. CONCLUSIONS: Numerous models are used to predict diabetes, and as there is an association between prediabetes and diabetes, researchers have also used such models for screening the prediabetic population. Although it is a new clinical practice to explore, differences in glycaemic metabolic profiles, potential complications, and methods of intervention between the two populations cannot be ignored, and such differences have led to poor validity and accuracy of the models. Therefore, there is no recommended optimal model, and it is not recommended to use existing models for risk identification in alternative populations; future studies should focus on improving the clinical relevance and predictive performance of existing models.

RESUMO

Electronic waste that has not been properly treated can lead to environmental contamination including of heavy metals, which can pose risks to human health. Infants, a sensitive group, are highly susceptible to heavy metals exposure. The aim of this study was to investigate the association between prenatal heavy metal exposure and infant birth outcomes in an e-waste recycling area in China. We analyzed cadmium (Cd), chromium (Cr), manganese (Mn), lead (Pb), copper (Cu), and arsenic (As) concentrations in 102 human milk samples collected 4 weeks after delivery. The results showed that 34.3% of participants for Cr, which exceeds the World Health Organization (WHO) guidelines, as well as the mean exposure of Cr exceeded the WHO guidelines. We collected data on the birth weight (BW) and length of infants and analyzed the association between metal concentration in human milk and birth outcomes using multivariable linear regression. We observed a significant negative association between the Cd concentration in maternal milk and BW in female infants (ß = -162.72, 95% CI = -303.16, -22.25). In contrast, heavy metals did not associate with birth outcomes in male infants. In this study, we found that 34.3% of participants in an e-waste recycling area had a Cr concentration that exceeded WHO guidelines, and there was a significant negative association between prenatal exposure to the Cd and infant BW in females. These results suggest that prenatal exposure to heavy metals in e-waste recycling areas may lead to adverse birth outcomes, especially for female infants.

RESUMO

Backgrounds: The prediabetes population is large and easily overlooked because of the lack of obvious symptoms, which can progress to diabetes. Early screening and targeted interventions can substantially reduce the rate of conversion of prediabetes to diabetes. Therefore, this study systematically reviewed prediabetes risk prediction models, performed a summary and quality evaluation, and aimed to recommend the optimal model. Methods: We systematically searched five databases (Cochrane, PubMed, Embase, Web Of Science, and CNKI) for published literature related to prediabetes risk prediction models and excluded preprints, duplicate publications, reviews, editorials, and other studies, with a search time frame of March 01, 2023. Data were categorized and summarized using a standardized data extraction form that extracted data including author; publication date; study design; country; demographic characteristics; assessment tool name; sample size; study type; and model-related indicators. The PROBAST tool was used to assess the risk of bias profile of included studies. Findings: 14 studies with a total of 15 models were eventually included in the systematic review. We found that the most common predictors of models were age, family history of diabetes, gender, history of hypertension, and BMI. Most of the studies (83.3%) had a high risk of bias, mainly related to under-reporting of outcome information and poor methodological design during the development and validation of models. Due to the low quality of included studies, the evidence for predictive validity of the available models is unclear. Interpretation: We should pay attention to the early screening of prediabetes patients and give timely pharmacological and lifestyle interventions. The predictive performance of the existing model is not satisfactory, and the model building process can be standardized and external validation can be added to improve the accuracy of the model in the future.

RESUMO

ABSTRACT: Background: Dexmedetomidine (DEX) attenuates intestinal I/R injury, but its mechanism of action remains to be further elucidated. Protein disulfide isomerase A3 (PDIA3) has been reported as a therapeutic protein for the prevention and treatment of intestinal I/R injury. This study was to investigate whether PDIA3 is involved in intestinal protection of DEX and explore the underlying mechanisms. Methods: The potential involvement of PDIA3 in DEX attenuation of intestinal I/R injury was tested in PDIA3 Flox/Flox mice and PDIA3 conditional knockout (cKO) in intestinal epithelium mice subjected to 45 min of superior mesenteric artery occlusion followed by 4 h of reperfusion. Furthermore, the α2-adrenergic receptor (α2-AR) antagonist, yohimbine, was administered in wild-type C57BL/6N mice intestinal I/R model to investigate the role of α2-AR in the intestinal protection conferred by DEX. Results: In the present study, we identified intestinal I/R-induced obvious inflammation, endoplasmic reticulum (ER) stress-dependent apoptosis, and oxidative stress, and all the aforementioned changes were improved by the administration of DEX. PDIA3 cKO in the intestinal epithelium have reversed the protective effects of DEX. Moreover, yohimbine also reversed the intestinal protection of DEX and downregulated the messenger RNA and protein levels of PDIA3. Conclusion: DEX prevents PDIA3 decrease by activating α2-AR to inhibit intestinal I/R-induced inflammation, ER stress-dependent apoptosis, and oxidative stress in mice.

RESUMO

Introduction: Depression is a common psychiatric disorder characterized by persistent low mood, reduced interest, and slowed thinking. Young adults are the main first-onset group for depression in all categories of the population. Program for education and enrichment of relational skills (PEERS) training, a program for the Education and Enrichment of Relational Skills, has been used in Europe and America for people with various types of social disorders with good results. A Chinese adaptation of the PEERS training program may be a new approach to help youth with depression return to society as soon as possible. This study aimed to construct and optimize a social skills training program for Chinese young adults with depression and to validate the impact of the program. Materials and methods and analysis: The aim of this trial protocol is to evaluate the efficacy of the localized PEERS training program on social competence, depressed mood in a Chinese young adult population with depression. The primary outcome will be a change in self-reported depressive symptoms from baseline to week 3 post-randomization to week 6 post-randomization measured using the Liebowitz social anxiety scale (LSAS). Secondary outcomes include the rate of decline in severe social anxiety, the Social Avoidance and Distress Scale (SAD), the Social Self-Efficacy Scale (PSSE), and the Hamilton Depression Scale (HAMD-17). Data for each assessment will be collected at baseline, week 3 of the trial, and week 6 of the trial. Ethics and dissemination: Ethics approval was obtained from the Hospital Ethics Committee. Findings will be disseminated through scientific journals, conferences, and university courses. Trial registration number: [http://www.chictr.org.cn/], identifier [ChiCTR2100046050].

RESUMO

Background: Remifentanil protects against intestinal ischemia/reperfusion (I/R) injury; however, its exact mechanism remains to be elucidated. The objective of this study was to investigate the underlying molecular mechanism of remifentanil in intestinal I/R injury in mice. Methods: We evaluated the intestine-protective effect of remifentanil in adult male mice with 45 min superior mesenteric artery occlusion followed by 4 h reperfusion by determining the following: intestinal Chiu's scores, diamine oxidase, and intestinal fatty acid binding protein in serum; the apoptotic index, lipid peroxidation product malondialdehyde (MDA), and superoxide dismutase (SOD) activity in the intestinal mucosa; and the intestinal mRNA and protein expressions of Bip, CHOP, caspase-12, and cleaved caspase-3, reflecting endoplasmic reticulum (ER) stress. Furthermore, conditional knockout mice, in which the protein disulfide isomerase A3 (PDIA3) gene was deleted from the intestinal epithelium, and SB203580 (a selective p38MAPK inhibitor) were used to determine the role of PDIA3 and p38MAPK in I/R progression and intestinal protection by remifentanil. Results: Our data showed that intestinal I/R induced obvious oxidative stress and endoplasmic reticulum stress-related cell apoptosis, as evidenced by an increase in the intestinal mucosal malondialdehyde, a decrease in the intestinal mucosal SOD, and an increase in the apoptotic index and the mRNA and protein expression of Bip, CHOP, caspase-12, and cleaved caspase-3. Remifentanil significantly improved these changes. Moreover, the deletion of intestinal epithelium PDIA3 blocked the protective effects of remifentanil. SB203580 also abolished the intestinal protection of remifentanil and downregulated the mRNA and protein expression of PDIA3. Conclusion: Remifentanil appears to act via p38MAPK to protect the small intestine from intestinal I/R injury by its PDIA3-mediated antioxidant and anti-ER stress properties.

RESUMO

Influx of activated neutrophils into the lungs is the histopathologic hallmark of acute lung injury (ALI) after intestinal ischemia/reperfusion (I/R). Neutrophils can release DNA and granular proteins to form cytotoxic neutrophil extracellular traps (NETs), which promotes bystander tissue injury. However, whether NETs are responsible for the remote ALI after intestinal I/R and the mechanisms underlying the dissemination of harmful gut-derived mediators to the lungs are unknown. In the C57BL/6J mouse intestinal I/R model, DNase I-mediated degradation and protein arginine deiminase 4 (PAD4) inhibitor-mediated inhibition of NET treatments reduced NET formation, tissue inflammation, and pathological injury in the lung. High-mobility group protein B1 (HMGB1) blocking prevented NET formation and protected against tissue inflammation, as well as reduced cell apoptosis and improved survival rate. Moreover, recombinant human HMGB1 administration further drives NETs and concurrent tissue toxic injury, which in turn can be reversed by neutrophil deletion via anti-Ly6G Ab i.p. injection. Furthermore, global MyD88 deficiency regulated NET formation and alleviated the development of ALI induced by intestinal I/R. Thus, HMGB1 released from necroptotic enterocytes caused ALI after intestinal I/R by inducing NET formation. Targeting NETosis and the HMGB1 pathway might extend effective therapeutic strategies to minimize intestinal I/R-induced ALI.

RESUMO

OBJECTIVE: To explore the change in the medical serviceability of primary hospitals since the establishment of the Huzhou No. 1 People's Hospital medical care group incorporating the integrated delivery system. METHODS: With reference to the "Grade Evaluation Standard of General Hospitals in Zhejiang Province" and the "Guidelines for Service Capacity Evaluation of Township Hospitals (2019 Edition)," we analyzed the influence of the integrated delivery system on the capacity of primary medical services and selected the targeted core indicators. From the four dimensions of diagnosis and treatment breadth, diagnosis and treatment efficiency, surgical ability, and patient satisfaction, an index evaluation system was established to explore the changes in the medical serviceability in primary hospitals. RESULTS: The measurements were aimed at four specific issues, that is, the low medical technology level of grassroots personnel, the poor information communication among medical institutions, the difficulty in recruiting people, and the imperfect training mechanism in primary hospitals. After establishing a series of measurements related to the problems faced by the primary healthcare sector in China, the score of breadth of diagnosis and treatment, efficiency of diagnosis and treatment ability, surgical ability, and patient satisfaction of the primary hospitals in our medical group have greatly increased. CONCLUSION: The integrated delivery system improved the primary hospitals' medical health ability obviously. Our study also provides various useful and operable suggestions for primary healthcare.

RESUMO

BACKGROUND: With the continuous development of modern society, the management of chronic diseases has become the focus of the medical community in China. In particular, diabetes is a chronic disease that cannot be ignored. China has built an integrated delivery system to deal with imminent health problems. The purpose of this study is to investigate the effects of integrated rural supply system in China. METHODS: We selected 1,061 patients with diabetes from the Zhili Town Health Center's hospital information system. We tracked and studied their outpatient and inpatient expenses, treatment behaviors, incidence of complications, and satisfaction over 5 years. We compared the data collected from 2014 to 2019 to determine the trends of these four factors and the effects of the integrated delivery system for patients with diabetes. RESULTS: We found that the average costs for diabetes patients in outpatient and inpatient departments were increasing slightly every year. The number of patients in tertiary hospitals has decreased significantly, while the number of patients in community hospitals (primary hospitals) has increased, and the number of patients in secondary hospitals has remained relatively unchanged. Meanwhile, the expenses per visit were also lower over this period in hospitals at all levels. Diabetes complications have been increasing marginally, and there is a relatively high degree of satisfaction among patients and doctors in primary hospitals, which is rising. CONCLUSIONS: Considering the various needs of people in different stages of life, the integrated delivery system provides and manages continuous services such as health promotion, disease prevention, diagnosis, treatment, rehabilitation, and management through cooperation between institutions at different levels of the health system.

RESUMO

INTRODUCTION: Efficacy of aliskiren combination therapy with other antihypertensive has been evaluated in the treatment of patients with hypertension in recent systematic reviews. However, most previous reviews only focused on one single health outcome or one setting, none of them made a full summary that assessed the impact of aliskiren combination treatment comprehensively. As such, this umbrella review based on systematic reviews and meta-analyses is aimed to synthesise the evidences on efficacy, safety and tolerability of aliskiren-based therapy for hypertension and related comorbid patients. METHODS AND ANALYSIS: A comprehensive search of PubMed, EMBASE, Cochrane Library, CNKI published from inception to August 2020 will be conducted. The selected articles are systematic reviews which evaluated efficacy, safety and tolerability of aliskiren combination therapy. Two reviewers will screen eligible articles, extract data and evaluate quality independently. Any disputes will be resolved by discussion or the arbitration of a third person. The quality of reporting evidence will be assessed using the Assessment of Multiple Systematic Reviews V.2 tool tool. We will take a mixed-methods approach to synthesising the review literatures, reporting summary of findings tables and iteratively mapping the results. ETHICS AND DISSEMINATION: Ethical approval is not required for the study, as we would only collect data from available published materials. This umbrella review will be also submitted to a peer-reviewed journal for publication after completion. PROSPERO REGISTRATION NUMBER: CRD42020192131.

RESUMO

OBJECTIVES: To review and examine the evidence of the value of pressure injury risk assessment scales in intensive care patients. RESEARCH METHODOLOGY: We searched MEDLINE, Embase, CINAHL, Web of Science, the Cochrane Library, China Biomedical Literature Service System, VIP Database and CNIK from inception to February 2019. Two reviewers independently assessed articles' eligibility and risk of bias using the Quality Assessment of Diagnostic Accuracy Studies-II (QUADAS-2). We used a hierarchical summary receiver operating characteristics (HSROC) model to conduct the meta-analysis of diagnostic accuracy. RESULT: Twenty-four studies were included, involving 16 scales and 15,199 patients in intensive care settings. Results indicated that the top four risk assessment scales were the Cubbin & Jackson Index (SEN = 0.84, SPE = 0.84, AUC = 0.90), the EVRUCI scale (SEN = 0.84, SPE = 0.68, AUC = 0.82), the Braden scale (SEN = 0.78, SPE = 0.61, AUC = 0.78), the Waterlow scale (SEN = 0.63, SPE = 0.46, AUC = 0.56). The Norton scale and the other eleven scales were tested in less than two studies and need to be further researched. CONCLUSION: The Braden scale, most frequently used in hospitals, is not the best risk assessment tool for critically ill patients. The Cubbin & Jackson Index has good diagnostic test accuracy. However, low quality of evidence and important heterogeneity were observed.

RESUMO

BACKGROUND: Since the implementation of the new medical reform in 2009, China has established and improved a series of medical security systems, established medical confederations based on four categories, and promoted the operation of the hierarchical diagnosis and treatment model. The purpose of this study is to analyze the effects of the matrix chronic diseases management platform developed from the integrated delivery system. To evaluate the effects of the matrix chronic diseases management platform developed from the integrated delivery system in China on expenses, medical seeking behaviors, compensation, and degree of satisfaction in hypertensive patients. A longitudinal and retrospective study was performed to investigate medical expenses, actual compensation ratios, medical behaviors, and the degree of satisfaction across different levels of medical institutions in hypertensive patients. METHODS: A total of 7,037 patients with hypertension aged 36-99 from Zhili Town Health Center were selected based on the diagnostic criteria of the Guidelines for Prevention and Treatment of Hypertension in China. Data was collected from the hospital's database and systems, and questionnaires were distributed to patients who attended the Department of Cardiology. Outcomes included inspection and drug expenses in the outpatient and inpatient departments, actual reimbursement ratios, number of visits across different levels of hospitals, expenditure per visit, medical behaviors, complications of patients, and the degree of satisfaction of both patients and doctors in primary hospitals. RESULTS: The average cost for hypertensive patients was shown to be increasing year by year in the outpatient and inpatient departments. The number of patients in tertiary hospitals decreased significantly, while the number of patients in community hospitals (primary hospitals) increased, and the number of patients in secondary hospitals has remained almost unchanged. Furthermore, expenses per visit in hospitals across all levels also decreased during the study period. The primary complications of hypertension were cerebrovascular disease and coronary heart disease, which showed a slightly increasing trend. The degree of satisfaction of patients and doctors in primary hospitals was relatively high, and rose from 2014 to 2019. CONCLUSIONS: The matrix chronic diseases management platform developed from the integrated delivery system built in Huzhou No.1 Hospital had a positive effect on improving the reimbursement and satisfaction of patients with hypertension.

RESUMO

BACKGROUND: Intestinal ischemia-reperfusion (I/R) injury is a common clinical event with high mortality, but its mechanism is elusive. Although long noncoding RNAs (lncRNAs) have recently emerged as critical molecules in I/R damage in other organs, the changes in their expression and potential roles in intestinal I/R remain unclear. METHODS: The expression profiles of both lncRNAs and mRNAs in mouse intestinal mucosa after intestinal I/R were explored by a microarray approach, and their biological functions were elucidated by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. Then, some lncRNAs were further verified by qRT-PCR. Based on the coding-noncoding gene coexpression (CNC) network analyses, the role of lncRNA AK089510 in intestinal I/R-induced intestinal mucosa apoptosis was investigated by knockdown assay in vitro. RESULTS: A total of 3602 aberrantly expressed lncRNAs (1503 upregulated and 2099 downregulated) and 3158 mRNAs (1528 upregulated and 1630 downregulated) were identified. The dysregulated transcripts were enriched in the lipid metabolic process, apoptotic process, reactive oxygen species metabolic process, MAPK, TNF, ErbB, mTOR, and FoxO signaling pathways, and so on. The overexpression of lncRNA AK089510 was validated by qRT-PCR, and the CNC analysis revealed its target mRNAs. AK089510-siRNA reduced Casp6 and Casp7 expression and suppressed intestinal epithelial cell apoptosis after oxygen-glucose deprivation treatment. CONCLUSIONS: Our study revealed the lncRNA and mRNA expression patterns in mouse intestinal mucosa after intestinal I/R and predicted their potential functions and pathways. We identified AK089510 as a novel lncRNA involved in the apoptosis of intestinal mucosa, advancing our understanding of the molecular mechanisms of intestinal I/R injury.

RESUMO

Background: To date, the effect of vasopressin on organ damages after acute mesenteric ischemia (MI) remains poorly understood. Aims: To investigate the effect of terlipressin, a selective vasopressin V1 receptor agonist, versus norepinephrine on the intestinal and renal injuries after acute MI, and to explore the underlying mechanism of terlipressin. Methods: Acute MI model was produced by clamping the superior mesenteric artery for 1 hour. Immediately after unclamping, terlipressin or norepinephrine was intravenously administered for 2 hours. Meanwhile, in vitro, RAW264.7 cells were treated with lipopolysaccharide or lipopolysaccharide+terlipressin. In addition, wortmannin was used to determine the role of phosphoinositide 3-kinase (PI3K)/ protein kinase B (Akt) pathway in the potential impacts of terlipressin. Results: MI led to severe hypotension, caused notable intestinal and renal impairments and resulted in high mortality, which were markedly improved by terlipressin or norepinephrine. Terlipressin increased mean arterial pressure, decreased intestinal epithelial cell apoptosis, inhibited the generation of M1 macrophage in intestinal and renal tissues, and hindered the release of inflammatory cytokines after MI. Moreover, in cultured macrophages, terlipressin reduced the mRNA level of specific M1 markers and the release of inflammatory cytokines caused by lipopolysaccharide challenge. Wortmannin decreased the expression of PI3K and Akt induced by terlipressin in cells and in tissues, and abolished the above protective effects conferred by terlipressin. Conclusions: Terlipressin or norepinephrine could effectively improve organ damages and mortality after acute MI. Terlipressin elevates blood pressure and inhibits intestinal epithelial apoptosis and macrophage M1 polarization via the PI3K/Akt pathway.

RESUMO

Mental disorders are thought to affect various clinical outcomes during the perioperative period. Among them, anxiety and depression are 2 of the most common types. However, the impacts of anxiety or depression on propofol requirements remain unclear. This study aimed to investigate the effects of anxiety or depression symptoms on the propofol requirements for sedation in females. This study recruited female patients aged 18 to 65 years, with American Society of Anesthesiologists physical status classification of 1 to 2, who were scheduled for hysteroscopic surgery under propofol-based intravenous anesthesia. The day before surgery, the Hospital Anxiety and Depression Scale (HADS) was used to assess the symptoms of anxiety and depression within the past 6 months. Target-controlled propofol was gradually titrated to achieve 3 desired levels of sedation: Modified Observer's Assessment of Alertness/Sedation scale (MOAA/S) score 3, MOAA/S score 1, and MOAA/S score 1 and Narcotrend Index <65. The effect-site concentration of propofol correlated with HADS-Anxiety scores for the sedation levels of MOAA/S 3 and 1 (r = .249, P = .008; and r = .190, P = .045, respectively). However, the propofol requirements did not correlate with HADS-Depression scores at any sedation level. In conclusion, female patients with anxiety symptoms, but not depression symptoms, required a higher dose of propofol for sedation in hysteroscopy.

RESUMO

BACKGROUND: Aliskiren is a newly developed drug. Its role in lowering BP has been recognized. However, the role of aliskiren in treating heart and renal diseases are still controversial. OBJECTIVE: To evaluate the existing evidence about clinical efficacy, safety and tolerability of aliskiren monotherapy (AM). METHODS: An umbrella review of systematic reviews of interventional studies. We searched Pubmed, Embase and Cochrane Library up to June 2019. Two reviewers applied inclusion criteria to the select potential articles independently. The extract and analyze of accessible data were did by two reviewers independently too. Discrepancies were resolved with discussion or the arbitration of the third author. RESULTS: Eventually, our review identified 14 eligible studies. Results showed that for essential hypertension patients, aliskiren showed a great superiority over placebo in BP reduction, BP response rate and BP control rate. Aliskiren and placebo, ARBs or ACEIs showed no difference in the number or extent of adverse events. For heart failure patients, AM did not reduce BNP levels (SMD -0.08, - 0.31 to 0.15) or mortality rate (RR 0.76, 0.32 to 1.80), but it decreased NT-proBNP (SMD -0.12, - 0.21 to - 0.03) and PRA levels (SMD 0.52, 0.30 to 0.75), increased PRC levels (SMD -0.66, - 0.8 to - 0.44). For patients who are suffered from hypertension and diabetes and/or nephropathy or albuminuria at the same time, aliskiren produced no significant effects (RR 0.97, 0.81 to 1.16). CONCLUSION: We found solid evidence to support the benefits of aliskiren in the treatment of essential hypertension, aliskiren can produce significant effects in lowering BP and reliable safety. However, the effects of aliskiren in cardiovascular and renal outcomes were insignificant. TRIAL REGISTRATION: Study has been registered in PROSPERO (CRD42019142141).

RESUMO

BACKGROUND: The debate on lung-protective ventilation strategies for surgical patients is ongoing. Evidence suggests that the use of low tidal volume VT improves clinical outcomes. However, the optimal levels of PEEP and recruitment manoeuvre (RM) strategies incorporated into low VT ventilation remain unclear. METHODS: Several electronic databases were searched to identify RCTs that focused on comparison between low VT strategy and conventional mechanical ventilation (CMV), or between two different low VT strategies in surgical patients. The primary outcome was postoperative pulmonary complications (PPCs). The secondary outcomes were atelectasis, pneumonia, acute respiratory distress syndrome, and short-term mortality. Bayesian network meta-analyses were performed using WinBUGS. The odds ratios (ORs) and corresponding 95% credible intervals (CrIs) were estimated. RESULTS: Compared with CMV, low VT ventilation with moderate-to-high PEEP reduced the risk of PPCs (moderate PEEP [5-8 cm H2O]: OR 0.50 [95% CrI: 0.28, 0.89]; moderate PEEP+RMs: 0.39 [0.19, 0.78]; and high PEEP [≥9 cm H2O]+RMs: 0.34 [0.14, 0.79]). Low VT ventilation with moderate-to-high PEEP and RMs also specifically reduced the risk of atelectasis compared with CMV (moderate PEEP+RMs: OR 0.36 [95% CrI: 0.16, 0.87]; and high PEEP+RMs: 0.41 [0.15, 0.97]), whilst low VT ventilation with moderate PEEP was superior to CMV in reducing the risk of pneumonia (OR 0.46 [95% CrI: 0.15, 0.94]). CONCLUSIONS: The combination of low VT ventilation and moderate-to-high PEEP (≥5 cm H2O) seems to confer lung protection in surgical patients undergoing general anaesthesia. CLINICAL TRIAL REGISTRATION: PROSPERO (CRD42019144561).

RESUMO

INTRODUCTION: Aliskiren is a newly developed medicine. As one of the effective renin-angiotensin-aldosterone system inhibitors, its role in lowering blood pressure has been recognised. However, its safety and tolerability still remain controversial. The aim of the paper is to systematically summarise the published studies about the clinical efficacy and side effects of aliskiren monotherapy. METHODS AND ANALYSIS: A comprehensive review of PubMed, Embase and Cochrane Library databases published from inception until June 2019 will be conducted. The selected articles are meta-analyses that integrated the randomised controlled studies, which evaluated efficacy, safety and tolerability of aliskiren monotherapy. Two people will select eligible articles and extract data independently. Any disputes will be resolved by discussion or the arbitration of a third person. The quality of reporting evidence will be assessed using the AMSTAR 2 tool. Study selection process will be presented using a flowchart. We will re-analyse each outcome with the random effect methods if necessary. If possible, we will also calculate 95% prediction intervals for each random effect estimate, by using Egger's test to evaluate if the reporting bias existed. ETHICS AND DISSEMINATION: Ethical approval is not required for the study, as we only collected data from available published materials. This umbrella review will be also submitted to a peer-reviewed journal for publication after completion. PROSPERO REGISTRATION NUMBER: CRD42019142141.

RESUMO

Reperfusion of the ischemic intestine often leads to drive distant organ injury, especially injuries associated with hepatocellular dysfunction. The precise molecular mechanisms and effective multiple organ protection strategies remain to be developed. In the current study, significant remote liver dysfunction was found after 6 hours of reperfusion according to increased histopathological scores, serum lactate dehydrogenase (LDH), alanine aminotransferase (ALT)/aspartate aminotransferase (AST) levels, as well as enhanced bacterial translocation in a rat intestinal ischemia/reperfusion (I/R) injury model. Moreover, receptor-interacting protein kinase 1/3 (RIP1/3) and phosphorylated-MLKL expressions in tissue were greatly elevated, indicating that necroptosis occurred and resulted in acute remote liver function impairment. Inhibiting the necroptotic pathway attenuated HMGB1 cytoplasm translocation and tissue damage. Meanwhile, macrophage-depletion study demonstrated that Kupffer cells (KCs) are responsible for liver damage. Blocking HMGB1 partially restored the liver function via suppressed hepatocyte necroptosis, tissue inflammation, hepatic KCs, and circulating macrophages M1 polarization. What's more, HMGB1 neutralization further protects against intestinal I/R-associated liver damage in microbiota-depleted rats. Therefore, intestinal I/R is likely associated with acute liver damage due to hepatocyte necroptosis, and which could be ameliorated by Nec-1 administration and HMGB1 inhibition with the neutralizing antibody and inhibitor. Necroptosis inhibition and HMGB1 neutralization/inhibition, may emerge as effective pharmacological therapies to minimize intestinal I/R-induced acute remote organ dysfunction.
