RESUMEN

This study aims to systematically review the clinical features and outcome indicators in randomized controlled trial(RCT) of traditional Chinese medicine(TCM) intervention in septic kidney injury and provide a reference for optimizing clinical study design and building the core outcome set(COS) of TCM treatment of septic kidney injury. Computer searches were conducted on PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, VIP, and SinoMed to find published RCT of TCM intervention in septic kidney injury in the past five years, extract the basic characteristics, intervention measures, outcome indicators, and other data of included studies, and conduct descriptive analysis. 53 RCTs were included, and the sample size was mostly concentrated in 60-80 cases, with abdominal infection being the most common(15 articles, 83.3%) and the TCM syndrome of blood stasis being the most frequent(9 articles, 50.0%). The frequency of intervention methods from high to low were TCM decoction(28 articles, 52.8%), Chinese patent medicine(22 articles, 41.5%), and combined TCM therapy(3 articles, 7.5%); the intervention time of the trial was more than 7 d(34 articles, 69.4%). The risk of bias in included studies was unclear. A total of 84 outcome indicators were involved, which were divided into 9 fields, including 63 physical and chemical tests(305 times, 72.2%), 4 kinds of disease degree(48 times, 11.6%), 4 kinds of clinical effective rate(15 times, 3.6%), 1 kind of quality of life(1 time, 0.2%), 2 kinds of economic evaluation(14 times, 3.3%), 1 kind of TCM disease(9 times, 2.1%), 2 kinds of long-term prognosis(16 times, 3.8%), 2 kinds of safety events(6 times, 1.4%), and 5 other indicators(8 times, 0.7%). The cumulative frequency was 422 times, among which the outcome indicators with higher frequency were inflammatory factors(42 articles, 79.2%) and markers of renal function and kidney injury(40 articles, 75.5%). Only 1(1.9%) of the included articles mentioned primary and secondary outcome indicators, and 6 articles(11.3%) mentioned safety events, 13 articles(24.5%) mentioned economic assessment. The RCT quality of TCM intervention in septic renal injury was generally low, and the reference standards for sepsis, kidney injury, and TCM syndrome diagnosis were not uniform. There are some problems in outcome indicators, such as unclear distinction between primary and secondary indicators, neglect of endpoint indicators, lack of application of TCM characteristic indicators, and insufficient attention to safety events and economic assessment. It is suggested that the quality of clinical research methodology should be improved in the future, and the COS should be constructed to provide high-level evidence-based evidence for TCM intervention in septic kidney injury.

RESUMEN

INTRODUCTION: SBRT is an increasingly popular treatment for localized prostate cancer, though considerable variation in technical approach is common and optimal dose constraints are uncertain. In this study, we sought to identify dosimetric and patient-related predictors of acute rectal toxicity. METHODS: Patients included in this study were treated with prostate SBRT on a prospective institutional protocol. Physician-graded toxicity and patient-reported outcomes were captured at one week, one month, and three months following SBRT. DVH data were extracted and converted into relative volume differential DVHs for NTCP modeling. Patient- and disease-related covariates along with NTCP model predictions were independently tested for significant association with physician-graded toxicity or a decline in bowel-related QoL. A multivariate model was constructed using forward selection, and significant parameter cutoff values were obtained with Fischer's exact test to group patients by risk of developing physician-graded toxicity or detriments in patient-reported QoL. RESULTS: One hundred and three patients treated for localized prostate cancer with SBRT were included in our analysis. 52% of patients experienced a clinically significant decline in bowel-related QOL within 1 week of completion of treatment, while only 27.5% of patients developed grade 2+ physician-graded rectal toxicity. Sequential feature selection multivariate logistic regression identified rectal V22.5 Gy (p = 0.001) and D19% (p = 0.001) as independent predictors of clinically significant toxicity, while rectal V20Gy (p = 0.004) and D25.3% (p = 0.007) were independently correlated with physician-graded toxicity. Global multivariate step-wise logistic regression identified only D19% (p = 0.001) and V20Gy (p = 0.004) as independent predictors of acute bowel bother or physician-graded rectal toxicity respectively. CONCLUSIONS: Moderate doses to large rectal volumes, D19% and V20Gy, were associated with an increased incidence of a clinically significant decrease in patient-reported bowel QOL and physician-scored grade 2+ rectal toxicity, respectively. These dosimetric parameters may help practitioners mitigate acute toxicity in patients treated with prostate SBRT.

RESUMEN

OBJECTIVE: To evaluate the efficacy and safety of pulmonary rehabilitation for exercise tolerance and quality of life improvement in idiopathic pulmonary fibrosis. METHODS: We searched PubMed, Cochrane Library, Embase, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang Database, and Chongqing VIP for randomized controlled trials that compared pulmonary rehabilitation with usual care for idiopathic pulmonary fibrosis. The risk of bias and certainty of evidence were assessed using Cochrane Collaboration's Risk of Bias tool and the Grading of Recommendations, Assessment, Development and Evaluation criteria. RESULTS: Eleven trials in total with 549 participants. Compared with usual care, pulmonary rehabilitation significantly increased 6-minute walking distance (mean difference: 35.2m, 95% confidence intervals: 25.4m-44.9m; ten trials; 447 participants; moderate), decreased the St George's Respiratory Questionnaire total scores (mean difference: -9.11, 95% confidence intervals: -10.78 to -7.43; six trials; 303 participants; moderate), and reduced the modified Medical Research Council scores were lower (mean difference: -0.76, 95% confidence intervals: -1.25 to -0.27; three trials; 196 participants; low). Improvements were noted in forced vital capacity percent-predicted (mean difference: 4.88, 95% confidence intervals: 2.67 to 7.10; four trials; 214 participants; moderate) and diffusing capacity for carbon monoxide (mean difference: 4.71, 95% confidence intervals: 0.96 to 8.46; six trials; 358 participants; low). CONCLUSIONS: Pulmonary rehabilitation may significantly improve exercise tolerance and quality of life in idiopathic pulmonary fibrosis patients, but the quality of evidence was low to moderate. Large sample, multicenter, randomized controlled trials are needed to verify the efficacy and safety of pulmonary rehabilitation.

RESUMEN

The performance of selective catalyst reduction systems highly depends on the degree of mixing between NH3 and NOx and the flow uniformity of velocity and concentration, which are sensitive to several parameters such as the installment of gate leafs, a hybrid grid, a straightener, and the ammonia injection method. In this work, computational fluid dynamics was applied to investigate these parameters in heat recovery steam generators. Performance of gate leafs and a new type of hybrid grid was considered. Analyses showed that gate leafs significantly improved the uniformity of velocity distribution and that the new type of hybrid grid improved the uniformity of concentration distribution. The velocity relative standard deviation decreased from 19.6% to 5.4%, and the concentration relative standard deviation decreased from 70% to 12.7%. Experiments also qualitatively confirmed the reliability of simulation results. Moreover, the hybrid grid was optimized with different structures. Results indicated that a 30° crossed angle could obtain a better mixing between NH3 and NOx with a slight decrease in pressure. In addition, an optimal injection method of the ammonia injection grid was designed, and it was helpful in conducting the field operation. The relationship between the thickness of the straightener and the incident angle at the entrance of catalyst layer was discussed.

RESUMEN

BACKGROUND: Late urinary symptom flare has been shown to occur in a small subset of men treated with ultra- hypofractionated stereotactic body radiotherapy (SBRT) for prostate cancer. The purpose of this study was to use normal tissue complication probability modeling in an effort to derive SBRT specific dosimetric predictor's of late urinary flare. MATERIAL AND METHODS: Two hundred and sixteen men were treated for localized prostate cancer using ultra- hypofractionated SBRT. A dose of 35-36.25 Gy in 5 fractions was delivered to the prostate and proximal seminal vesicles. Functional surveys were conducted before and after treatment to assess late toxicity. Phenomenologic NTCP models were fit to bladder DVHs and late urinary flare outcomes using maximum likelihood estimation. RESULTS: Twenty-nine patients experienced late urinary flare within two years of completion of treatment. Fitting of bladder DVH data to a Lyman NTCP model resulted in parameter estimates of m, TD50, and n of 0.19 (0-0.47), 38.7 Gy (31.1-46.4), and 0.13 (-0.14-0.41), respectively. Subsequent fit to a hottest volume probit model revealed a significant association of late urinary flare with dose to the hottest 12.7% of bladder volume. Multivariate analysis resulted in a final model that included patient age and hottest volume probit model predictions. Kaplan-Meier analysis demonstrated a two-year urinary flare free survival of 95.7% in patients 65 years or older with a bladder D12.7% of 33.5 Gy or less, compared to 74.5% in patients meeting none of these criteria. CONCLUSION: NTCP modeling of late urinary flare after ultra-hypofractionated prostate SBRT demonstrates a relatively small volume effect for dose to the bladder, suggesting that reduction of volume receiving elevated dose will result in decreased incidence of late urinary toxicity. Future studies will be needed to examine the impact of dose to other potential sources of late genitourinary toxicity.

RESUMEN

BACKGROUND: Stereotactic body radiotherapy (SBRT) has emerged as an effective treatment for localized prostate cancer. However, prostate specific antigen (PSA) kinetics after prostate SBRT have not been well characterized. The purpose of this study was to analyze the trend in PSA decline following robotic SBRT from a prospective cohort of patients. MATERIAL AND METHODS: In total 175 patients were treated definitively for localized prostate cancer to a dose of 35-36.25 Gy in 5 fractions using robotic SBRT in the absence of androgen deprivation therapy (ADT). PSA and testosterone were collected at regular intervals following treatment and patients were assessed for biochemical failure and benign PSA bounce. A PSA nadir threshold of 0.5 ng/ml was used as a predictor of long-term disease-free survival. Multivariate logistic regression was used to assess the effect of disease specific covariates on the likelihood of achieving a PSA nadir less than threshold. PSA kinetics were analyzed a multi-component exponential model accounting for benign and malignant sources of PSA. RESULTS AND CONCLUSION: At a median follow-up of 3 years, 70% of patients achieved a PSA nadir below 0.5 ng/ml with a median PSA nadir of 0.3 ng/ml at a median time to nadir of 30 months. In our cohort, 36.2% experienced a benign PSA bounce. Absence of PSA bounce, initial PSA, and testosterone at the time of nadir proved to be significant predictors of achieving a PSA nadir below threshold. PSA kinetics after prostate SBRT were well described with a functional volume model with fitted half-lives of 4.4 and 14.8 months for malignant and benign sources of PSA, respectively. Patients treated with prostate SBRT experience an initial period of rapid PSA decline followed by a slow decline which will likely result in lower PSA nadirs after longer follow-up. The long-term disease specific impacts of these results remain to be determined.

RESUMEN

PURPOSE: Stereotactic body radiation therapy (SBRT) has been established as a safe and effective treatment for prostate cancer. SBRT requires high accuracy to reduce treatment margins. Metal hip prostheses create artifacts that distort pelvic imaging and potentially decrease the accuracy of target/organ at risk (OAR) identification and radiation dose calculations. Data on the safety and efficacy of SBRT after hip replacement is limited. This single-institution study sought to evaluate the safety and local control following SBRT for prostate cancer in men with hip replacements. METHODS: 23 patients treated with localized prostate cancer and a history of pre-treatment hip replacement, treated with SBRT from 2007 to 2017 at MedStar Georgetown University Hospital were included in this retrospective analysis. Treatment was administered with the CyberKnife® (Accuray Incorporated, Sunnyvale, CA) at doses of 35 Gy or 36.25 Gy in 5 fractions. The targets and OARs were identified and contoured by a single experienced Radiation Oncologist (SPC). The adequacy of the CT and T2W MRI images for treatment planning was assessed with a three-point scale (good, adequate, or suboptimal). During treatment planning, care was taken to avoid treatment beams that directly traversed the hip prosthesis. Toxicities were recorded and scored using the Common Terminology Criteria for Adverse Events version 4.0 (CTCAE v.4.0). Local recurrence was confirmed by magnetic resonance imaging and/or prostate biopsy. RESULTS: The median follow-up was seven years. The patients were elderly (median age = 71 years) with a high rate of comorbidities (Charlson Comorbidity Index > 2 in 25%). Four patients had bilateral hip replacements. The majority of patients were low to intermediate risk per the D'Amico classification. Around 13% received upfront ADT. In total, 13 patients were treated with 35 Gy, and 10 were treated with 36.25 Gy. The rates of late > Grade 3 GU toxicity and > Grade 2 GI toxicity were 8.6% and 4.3%, respectively. There were no Grade 4 or 5 toxicities. Six patients (26%) developed a local recurrence at a median time of 7.5 years. Of these six patients, four had unilateral hip replacements and two had bilateral. Three underwent salvage cryotherapy and three received salvage ADT. CONCLUSIONS:  In the general population, high-grade toxicities and local recurrences are uncommon following prostate SBRT. However, in this cohort of patients with prior hip replacements, prostate SBRT had higher than expected rates of late toxicity and local recurrence. In the opinion of the authors, such patients should be counseled regarding an elevated risk of late toxicity and local recurrence with prostate SBRT. With its ultrasound guidance, brachytherapy would have the advantage of circumventing the need for MRI/CT-based imaging and thus may represent a preferable radiation alternative in this patient population. If these patients are treated with SBRT, they should be monitored closely for local recurrence so early salvage can be performed. We hope that recent advances in metal artifact reduction techniques and dose-calculation algorithms will improve future outcomes.

RESUMEN

Introduction/background: Phosphatase and tensin homolog (PTEN) genomic deletions and transmembrane protease, serine 2/v-ets avian erthyroblastosis virus E26 oncogene homolog (ERG) rearrangements are two of the most common genetic abnormalities associated with prostate cancer. Prior studies have demonstrated these alterations portend worse clinical outcomes. Our objective is to evaluate the impact of biopsy-determined PTEN losses and TMPRSS2-ERG fusion on biochemical progression-free survival (bPFS) and overall survival (OS) in patients who receive SBRT for localized prostate cancer. Methods/materials: Patients received SBRT for localized prostate cancer on a prospective quality-of-life (QoL) and cancer outcomes study. For each patient, the single biopsy core with the highest grade/volume of cancer was evaluated for PTEN and ERG abnormalities. Differences in baseline patient and disease characteristics between groups were analyzed using ANOVA for age and χ2 for categorical groupings. bPFS and OS were calculated using the Kaplan Meier (KM) method with Log-Rank test comparison between groups. Predictors of bPFS and OS were identified using the Cox proportional hazards method. For all analyses, p <0.05 was considered statistically significant. Results: Ninety-nine consecutive patients were included in the analysis with a median follow-up of 72 months. A statistically significant improvement in bPFS (p = 0.018) was observed for wild type ERG patients with an estimated 5-year bPFS of 94.1% vs. 72.4%. Regarding PTEN mutational status, significant improvements in were observed in both bPFS (p = 0.006) and OS (p < 0.001), with estimated 5-year bPFS rates of 91.0% vs. 67.9% and 5-year OS rates of 96.4% vs. 79.4%. When including both ERG and PTEN mutational status in the analysis, there were statistically significant differences in both bPFS (p = 0.011) and OS (p < 0.001). The estimated 5-year bPFS rates were 100%, 76.6%, 72.9%, and 63.8% for patients with ERG+/PTEN+, ERG-/PTEN+, ERG+/PTEN-, and ERG-/PTEN- phenotypes respectively. The estimated 5-year OS rates were 93.9%, 100%, 80.0%, and 78.7% for patients with ERG+/PTEN+, ERG-/PTEN+, ERG+/PTEN-, and ERG-/PTEN- phenotypes respectively. Conclusion: ERG rearrangements and PTEN deletions detected on biopsy samples are associated with poorer oncologic outcomes in prostate cancer patients treated with SBRT and merit further study in a dedicated prospective trial.

RESUMEN

Employees' Workplace Deviant Behavior (WDB) is an organizational threat to its sustainability. This study examines the impact of the supervisors' role in improving organizational behavior because of the gap in the body of knowledge indicating the inconsistency, paucity, and uncertainties of relationships between variables when relating to their underpinning theories. The conceptualized model consists of the impact of family supportive supervisor behavior (FSSB) on workers' workplace deviant behavior (WDB) while considering Affective Commitment and Work-Family Supportive Behavior Attribution between the key variables. In terms of methodology, this quantitative study analyzed 321 valid surveys through descriptive and inferential statistics to ascertain if FSSB negatively impacts employees' WDB. As findings and novelty of this study, FSSB is found to negatively affect employees' WDB, while affective commitment mediates between FSSB and employees' WDB. Work-family supportive behavior attribution and personal life attribution of employees moderated the negative relationship between affective commitment and WDB, while work productivity attribution of employees had no significant effect as a moderator. With three (out of four) hypotheses supported by empirical evidence, this research has broadened previous studies of workers' WDB and offers organizations theoretical and practical recommendations for managing employees' WDB. More studies could be conducted in the future to address limitations in this research, examine other related theories in a new context, location, and/or culture, or select other suitable research methods.

RESUMEN

OBJECTIVE: To systematically evaluate the distribution characteristics of traditional Chinese medicine (TCM) syndromes in adult influenza patients and to provide a basis for the TCM syndrome differentiation of influenza. METHODS: The CNKI, CBM, Wanfang, VIP, PubMed, Embase, Cochrane Library databases were searched to collect cross-sectional studies on the distribution pattern of TCM syndromes in adult patients with influenza. The risk of bias assessment tool for cross-sectional studies developed by the Joanna Briggs Institute (JBI) evidence-based health care center was used to evaluate the literature quality, and the Stata 15.1 software was used to conduct a Meta-analysis of the pooled effect sizes of the included studies. RESULTS: A total of 11 studies with 4 367 influenza patients were included. Quality assessment results of JBI showed that the risk bias was higher in the sample size calculation, and the description of sampling modalities and response rate was unclear. There were 17 influenza syndromes after specification, and a single group rate Meta-analysis was performed of the syndromes with ≥ 50 incident cases showed that there were 9 syndromes with an incidence ≥ 10% and statistical significance, the top 5 syndromes were syndrome of wind and heat invading the defense [n = 1 583, RATE = 34.3%, 95% confidence interval (95%CI) was 22.2%-46.3%], syndrome of exterior cold and interior heat (n = 1 122, RATE = 36.1%, 95%CI was 21.2%-51.1%), syndrome of wind-cold fettering the exterior (n = 860, RATE = 19.4%, 95%CI was 10.7%-28.0%), syndrome of heat and toxin in the lung (n = 217, RATE = 17.1%, 95%CI was 9.1%-25.0%), and syndrome of disease involving both defense phase and qi phase (n = 184, RATE = 38.8%, 95%CI was 14.2%-63.5%). The results of the subgroup analysis in different geographical regions showed that the frequency of distribution of syndrome of wind and heat invading the defense and heat and toxin in the lung was higher in the South (RATE: 36.5%, 18.6%) than in the North (RATE: 30.9%, 15.4%), and the frequency of distribution of syndrome of wind-cold fettering the exterior and exterior cold and interior heat in the North (RATE: 23.8%, 40.1%) was higher than that in the South (RATE: 15.7%, 32.3%). CONCLUSIONS: There are 9 common TCM syndromes of influenza, including wind and heat invading the defense syndrome, exterior cold and interior heat syndrome, wind-cold fettering the exterior syndrome, heat and toxin in the lung syndrome, disease involving both defense phase and qi phase syndrome, wind and heat complicated by dampnessinvading the surface syndrome, wind and cold complicated by dampnessinvading the surface syndrome, defense phase syndrome and dampness and heatinvading the surface syndrome, which can provide a reference for the TCM syndrome differentiation and treatment of influenza.

RESUMEN

OBJECTIVE: The prognosis for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is not optimistic, and severe AECOPD leads to an increased risk of mortality. Prediction models help distinguish between high- and low-risk groups. At present, many prediction models have been established and validated, which need to be systematically reviewed to screen out more suitable models that can be used in the clinic and provide evidence for future research. METHODS: We searched PubMed, EMBASE, Cochrane Library and Web of Science databases for studies on risk models for AECOPD mortality from their inception to 10 April 2022. The risk of bias was assessed using the prediction model risk of bias assessment tool (PROBAST). Stata software (version 16) was used to synthesize the C-statistics for each model. RESULTS: A total of 37 studies were included. The development of risk prediction models for mortality in patients with AECOPD was described in 26 articles, in which the most common predictors were age (n = 17), dyspnea grade (n = 11), altered mental status (n = 8), pneumonia (n = 6) and blood urea nitrogen (BUN, n = 6). The remaining 11 articles only externally validated existing models. All 37 studies were evaluated at a high risk of bias using PROBAST. We performed a meta-analysis of five models included in 15 studies. DECAF (dyspnoea, eosinopenia, consolidation, acidemia and atrial fibrillation) performed well in predicting in-hospital death [C-statistic = 0.91, 95% confidence interval (CI): 0.83, 0.98] and 90-day death [C-statistic = 0.76, 95% CI: 0.69, 0.82] and CURB-65 (confusion, urea, respiratory rate, blood pressure and age) performed well in predicting 30-day death [C-statistic = 0.74, 95% CI: 0.70, 0.77]. CONCLUSIONS: This study provides information on the characteristics, performance and risk of bias of a risk model for AECOPD mortality. This pooled analysis of the present study suggests that the DECAF performs well in predicting in-hospital and 90-day deaths. Yet, external validation in different populations is still needed to prove this performance.

RESUMEN

In the present study, novel copper-doped zirconium-based MOF (UIO-66) and copper-doped iron-based UIO-66 catalysts were prepared by hydrothermal synthesis method to improve the removal performance of gaseous benzene. The characteristics of the catalysts were analyzed by means of XRD, SEM, XPS, BET, and EPR. The copper loading catalyst had high crystallinity and irregular globular. The three kinds of catalysts with different Cu/Fe ratios had regular cubic shape. Compared with the catalyst supported with single copper, the bimetal Cu/Fe modification had a certain adjustment effect on the morphology, which specifically reflected in the uniform size and shape of catalyst particles with better dispersibility. The factors of different metal loading, dose of H2O2, and reaction temperature on benzene removal have been studied. It has been observed that in heterogeneous advanced oxidation removal of benzene, 3-Cu@UIO-66 and Cu1.5/Fe1.5@UIO-66 achieved the highest benzene removal efficiency of 81.2% and 94.6%, respectively. EPR results showed that the increase of Cu loading and different Cu/Fe ratios promoted the yield of hydroxyl radicals, thus promoted the benzene removal efficiency. The efficiency of heterogeneous oxidation removal of benzene first increased and then decreased with the increase of temperature due to H2O2 instability. DFT calculations exhibited that the Feoct-Cu-O site was a more effective activation site than the single Feoct-O site. Dissociative adsorption occurred with the O-O bond of H2O2 cracked, and the formed hydroxyls parallel adsorbed on the benzene surface. The combination of benzene and hydroxyls was strong chemisorption with the torsion angle of benzene ring obviously turned. The work was of great importance for identifying the roles of the novel catalyst for the removal of benzene pollutant from waste gases.

RESUMEN

A series of adsorption/oxidation bifunctional material with different Fe(II) loading amounts was prepared by using ultrahigh crosslinking adsorption resin (LXQ-10) as a carrier and FeCl2 as an impregnating solution. The bifunctional material was characterized by BET, SEM, XRD, XPS, and EPR. The effects of Fe loading, reaction temperature, and space velocity on benzene adsorption efficiency were investigated using self-made experimental equipment to explore the optimal reaction condition. The adsorption results were fitted and analyzed by using four typical models: the quasi-first-order kinetic model, the quasi-second-order kinetic model, Elovich's kinetic model, and the Weber and Morris kinetic model. The quasi-first-order kinetic model had the highest R2 value (0.998) and the best applicability. The fitting effect of the Freundlich equation (R2 = 0.997) was better than that of the Langmuir equation (R2 = 0.919). Furthermore, the effects of Fe loading, H2O2 concentration, benzene inlet concentration, and temperature on the catalytic oxidation efficiency of benzene were studied. The catalytic oxidation efficiency of 3-Fe(II)/LXQ-10 was maintained at about 95% at a temperature of 303 K and an H2O2 concentration of 150 mmol/L. Compared with the adsorption efficiency, the catalytic oxidation efficiency of bifunctional resin materials in a heterogeneous Fenton system was remarkably improved and had excellent stability. A possible migration and transformation path during benzene removal was proposed according to the results of the analysis of GC-MS intermediates. This study provided a novel process for the adsorption and oxidative degradation of VOCs.

RESUMEN

Cerebral ischemic stroke is a high-risk disease and imposes heavy burdens on patients in china. Acupuncture has been used for thousands of years to treat motor dysfunction, cognitive disorder and language barrier caused by cerebral ischemic stroke. Acupoint lines, vertex middle line and anterior oblique line of vertex temple, are always employed to treat cerebral ischemic stroke. However, the mechanism of the two acupoint lines in relieving cerebral ischemic stroke needs further exploration. In the present study, scalp acupuncture treatment alleviated the motor dysfunction, brain damage, and cell death induced by middle cerebral artery occlusion (MCAO) in rats. Proteomics analysis and ultrastructure observation indicated that endoplasmic reticulum and lysosomes might involve in the mechanism of the scalp acupuncture treatment in suppressing MCAO-triggered neural deficits. Effect of the scalp acupuncture treatment on ER stress was then investigated and found that the activation of ER stress mediators, including PERK, IRE1, and ATF6, was downregulated after the scalp acupuncture treatment. Co-localisation analysis of KDEL and CD63 showed that the engulfment of ER fragments by lysosomes was accelerated by the scalp acupuncture treatment. Moreover, expression of pro-apoptotic protein CHOP, phosphorylated-JNK, cleaved capases-3 and -9 also decreased after the scalp acupuncture. In conclusion, the present study showed that scalp acupuncture of vertex middle line and anterior oblique line of vertex temple may alleviate cerebral ischemic stroke by inhibiting ER stress-accelerated apoptosis.

RESUMEN

Purpose: Intensity-modulated radiation therapy (IMRT) with brachytherapy boost for unfavorable prostate cancer has been shown to improve biochemical relapse-free survival compared to IMRT alone. Stereotactic body radiation therapy (SBRT) is a less-invasive alternative to brachytherapy. Early outcomes utilizing SBRT boost suggest low rates of high-grade toxicity with a maintained patient-reported quality of life. Here, we report the 5-year progression-free survival (PFS) and prostate cancer-specific survival (PCSS) of patients treated with IMRT plus SBRT boost. Materials and methods: Between 2008 and 2020, 255 patients with unfavorable prostate cancer were treated with robotic SBRT (19.5 Gy in three fractions) followed by fiducial-guided IMRT (45-50.4 Gy) according to an institutional protocol. For the first year, the patient's PSA level was monitored every 3 months, biannually for 2 years, and annually thereafter. Failure was defined as nadir + 2 ng/mL or a rising PSA with imaging suggestive of recurrence. Detection of recurrence also included digital rectal examination and imaging studies, such as MRI, CT, PET/CT, and/or bone scans. PFS and PCSS were calculated using the Kaplan-Meier method. Results: The median follow-up period was 71 months. According to the NCCN risk classification, 5% (13/255) of the patients had favorable intermediate-risk disease, 23% (57/255) had unfavorable intermediate-risk disease, 40% (102/255) had high-risk disease, and 32% (83/255) had very high-risk disease. Androgen deprivation therapy was administered to 80% (204/255) of the patients. Elective pelvic lymph node IMRT was performed in 28 (10%) patients. The PFS for all patients at 5 years was 81% (favorable intermediate risk, 91%; unfavorable intermediate risk, 89%; high-risk, 78%; and very-high risk, 72%). The PCSS for all patients at 5 years was 97% (favorable intermediate risk, 100%; unfavorable intermediate risk, 100%; high risk, 100%; and very high risk, 89%). Conclusion: The incidence of failure following IMRT plus SBRT for unfavorable prostate cancer remains low at 5 years.

RESUMEN

Background: Sepsis is a major public health problem that cannot be ignored in China and even in the world. However, the prevalence of sepsis in Chinese adults varies among different studies. Objective: To evaluate the prevalence of hospital-wide sepsis and intensive care unit (ICU) sepsis in Chinese adults. Methods: PubMed, EMBASE, Cochrane Library, Web of science, China National Knowledge Infrastructure, Chinese biomedical literature service system, Wanfang Database, and VIP databases were systematically searched for studies on sepsis in China published before March 2, 2022. Random effects model was used to calculate pooled prevalence estimates with 95% confidence interval. Subgroup and sensitivity analyses were performed to address heterogeneity. Funnel plots and Egger's test were used to assess the publication bias. Results: Overall, nine observational studies involving 324,020 Chinese patients (9,587 patients with sepsis) were analyzed. Four hospital-wide studies involving 301,272 patients showed pooled prevalence and mortality of 3.8% (95% CI: 2.9-4.7%, I 2 = 99.9%) and 26% (95% CI: 16-36%, I 2 = 98.0%), respectively. Five studies of ICU sepsis involving 22,748 patients presented pooled prevalence and mortality of 25.5% (95% CI: 13.9-37.0%, I 2 = 99.8%) and 40% (95%CI: 34-47%, I 2 = 95.9%), respectively. Subgroup analysis of sepsis in ICUs revealed that the pooled prevalence was higher among males [17% (95% CI 9-24%, I 2 = 99.6%)], in lung infections [66% (95%CI: 54-77%, I 2 = 98.7%)], and Gram-negative bacteria infections [37% (95%CI: 26-47%, I 2 = 98.3%)]. The pooled prevalence of sepsis, severe sepsis and septic shock was 25.5% (95%CI: 13.9-37.0%, I 2 = 99.8%), 19% (95%CI: 9-28%, I 2 = 99.6%), and 13% (95%CI: 7-19%, I 2 = 99.2%), respectively. Conclusions: Sepsis is prevalent in 25.5% of ICU patients in China, and sex, sepsis severity, infection site, causative microorganism, and infection type are significant influencing factors. Larger trials are needed to evaluate the prevalence of sepsis in China, which may help the development of global strategies for sepsis management.

RESUMEN

Background: There is growing evidence that sepsis survivors are at increased risk of developing new-onset atrial fibrillation, acute kidney injury, and neurological diseases. However, whether sepsis survivals increase the risk of dementia or cognitive impairment remains to be further explored. Objective: The objective of this study was to determine whether sepsis survivals increase the risk of dementia or cognitive impairment. Methods: We searched PubMed, Cochrane Library, Web of Science, and EMBASE databases for cohort studies or case-control studies from their inception to November 5, 2021. The quality of this study was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). The Stata software (version 15.1) was used to calculate the odds ratio (OR) of dementia or cognitive impairment in sepsis survivals. Subgroup and sensitivity analyses were performed to assess the source of heterogeneity. Funnel plots and Egger's test were used to detect the publication bias. Results: Eight studies (i.e., seven cohort studies and one case-control study) involving 891,562 individuals were included. The quality assessment results showed that the average score of NOS was over 7, and the overall quality of the included studies was high. Pooled analyses indicated that sepsis survivals were associated with an increased risk of all-cause dementia (OR = 1.62, 95% CI = 1.23-2.15, I 2 = 96.4%, p = 0.001). However, there was no obvious association between sepsis survivals and the risk of cognitive impairment (OR = 1.77, 95% CI = 0.59-5.32, I 2 = 87.4%, p = 0.306). Subgroup analyses showed that severe sepsis was associated with an increased risk of dementia or cognitive impairment (OR = 1.99, 95% CI = 1.19-3.31, I 2 = 75.3%, p = 0.008); such risk was higher than that of other unspecified types of sepsis (OR = 1.47, 95% CI = 1.04-2.09, I 2 = 97.6%, p = 0.029). Conclusion: Sepsis survivals are associated with an increased risk of all-cause dementia but not with cognitive impairment. Appropriate management and prevention are essential to preserve the cognitive function of sepsis survivors and reduce the risk of dementia.
