RESUMO

OBJECTIVE: This retrospective study aimed to investigate the factors influencing the occurrence of neutropenia in patients with endometrial cancer (EC) following adjuvant chemoradiotherapy (CRT). METHODS: Retrospective analysis of EC patients who underwent adjuvant CRT from January 2012 to June 2023 in the Department of Gynecology and Oncology of the First Affiliated Hospital of Shandong First Medical University. Neutropenia was defined as an Absolute Neutrophil Count (ANC) of peripheral blood neutrophils below 2 × 109/L. Factors affecting neutropenia in EC patients treated with CRT using Generalized Estimating Equation (GEE), and Logistic regression was used to further analyze the effect of adding radiotherapy to different chemotherapy cycles on neutropenia, so that patients receive optimal adjuvant CRT while the risk of neutropenia is appropriately controlled. RESULTS: A total of 144 patients met the inclusion criteria. They underwent 330 cycles of adjuvant chemotherapy, of whom 96 (66.7%) developed neutropenia, which occurred 140 times. The results of one-way GEE analysis showed that before CRT, White Blood Cell (WBC) (OR = 0.827; 95%CI, 0.701-0.976), ANC (OR = 0.749; 95%CI, 0.586-0.957), Absolute Monocyte Count (AMC) (OR = 0.047; 95%CI, 0.008-0.283), Blood Urea Nitrogen (BUN) (OR = 0.857; 95%CI, 0.741-0.991), platinum and docetaxel (platinum/docetaxel) dosing regimen (OR = 2.284; 95%CI, 1.130-4.618) were associated with neutropenia with adjuvant CRT for EC (p < 0.05), results of multifactorial GEE analysis showed that before adjuvant CRT ANC (OR = 0.552; 95%CI, 0.973-2.231), AMC (OR = 0.047; 95%CI, 0.004-0.052), platinum/docetaxel (OR = 2.437; 95%CI, 1.087-5.464) were an independent influence on neutropenia in adjuvant CRT for EC (p < 0.05). Multifactorial Logistic regression shows addition of radiotherapy to the first cycle of chemotherapy (OR = 4.413; 95%CI, 1.238-18.891) was an independent influence of neutropenia (p < 0.05). CONCLUSIONS: Patients with low pre-CRT ANC and AMC, platinum/docetaxel dosing regimens need to be closely monitored during each cycle of CRT. Also, the concurrent addition of radiotherapy should be avoided during the first cycle of chemotherapy.

RESUMO

Introduction: The global distribution and trends in the attributable burden of cataract risk have rarely been systematically explored. To guide the development of targeted and accurate cataract screening and treatment strategies, we analyzed the burden of cataract disease attributable to known risk factors. Method: This study utilized detailed cataract data from the Global Burden of Disease e 2019, and we analyzed disability-adjusted life years (DALYs) e each risk factor from 1990 to 2019. Additionally, we calculated estimated annual percentage changes (EAPCs) during the study period. Results: The results revealed that from 1990-2019, the global age-standardized DALYs of e attributable to particulate matter pollution, smoking, high fasting glucose plasma and high BMI showed steady downward trends (1990-2009: EAPC = -0.21 [-0.57 -0.14]); 2000-2009: EAPC = -0.95 [-1.01 -0.89]; 2010-2019: EAPC = -1.41 [-1.8 -1.02]). The age-standardized DALYs and mortality caused by each risk factor were highest in the low-middle sociodemographic index (SDI) region (EAPC = -1.77[(-2.19--1.34)]). The overall disease burden of cataracts is lower in males than in females. When analyzing the EAPCs of cataract disease burden for each risk factor individually, we found that the age-standardized disability-adjusted life years caused by particulate matter pollution and smoking decreased (PMP1990-2009: EAPC = -0.53 [-0.9--0.16]; 2000-2009: EAPC = -1.39 [-1.45--1.32]; 2010-2019: EAPC = -2.27 [-2.75--1.79]; smoking 2000 to 2009: EAPC = -1.51 [-1.6--1.43], 2009 to 2019: EAPC = -1.34 [-1.68--1])), while high fasting plasma glucose and high body mass index increased annually (HFPG1990 to 1999: EAPC = 1.27 [0.89-1.65], 2000 to 2009: EAPC = 1.02 [0.82-1.22], 2010-2019: EAPC = 0.44 [0.19-0.68]; HBMI 1990 to 1999: EAPC = 1.65 [1.37-1.94], 2000 to 2009: EAPC = 1.56 [1.43-1.68], 2010-2019: EAPC = 1.47 [1.18-1.77]). Disscussion: The burden of cataracts caused by ambient particulate matter and smoking is increasing in low, low-middle SDI areas, and specific and effective measures are urgently needed. The results of this study suggest that reducing particulate matter pollution, quitting smoking, controlling blood glucose, and lowering BMI could play important roles in reducing the occurrence of cataracts, especially in older people.

RESUMO

Objective: Currently, sentinel lymph node biopsy (SLNB) is increasingly used in endometrial cancer, but the rate of missed metastatic lymph nodes compared to systemic lymph node dissection has been a concern. We conducted a systematic review and meta-analysis to evaluate the false negative rate (FNR) of SLNB in patients with endometrial cancer and to explore the risk factors associated with this FNR. Data sources: Three databases (PubMed, Embase, Web of Science) were searched from initial database build to January 2023 by two independent reviewers. Research eligibility criteria: Studies were included if they included 10 or more women diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage I or higher endometrial cancer, the study technique used sentinel lymph node localization biopsy, and the reported outcome metrics included false negative and/or FNR. Study appraisal and synthesis methods: Two authors independently reviewed the abstracts and full articles. The FNR and factors associated with FNR were synthesized through random-effects meta-analyses and meta-regression. The results: We identified 62 eligible studies. The overall FNR for the 62 articles was 4% (95% CL 3-5).There was no significant difference in the FNR in patients with high-risk endometrial cancer compared to patients with low-risk endometrial cancer. There was no difference in the FNR for whether frozen sections were used intraoperatively. The type of dye used intraoperatively (indocyanine green/blue dye) were not significantly associated with the false negative rate. Cervical injection reduced the FNR compared with alternative injection techniques. Indocyanine green reduced the FNR compared with alternative Tc-99m. Postoperative pathologic ultrastaging reduced the FNR. Conclusions: Alternative injection techniques (other than the cervix), Tc-99m dye tracer, and the absence of postoperative pathologic ultrastaging are risk factors for a high FNR in endometrial cancer patients who undergo SLNB; therefore, we should be vigilant for missed diagnosis of metastatic lymph nodes after SLNB in such populations.

RESUMO

OBJECTIVES: Our study aims to investigate the impact of B-mode ultrasound (B-US) imaging, color Doppler flow imaging (CDFI), strain elastography (SE), and patient age on the prediction of molecular subtypes in breast lesions. METHODS: Totally 2272 multimodal ultrasound imaging was collected from 198 patients. The ResNet-18 network was employed to predict four molecular subtypes from B-US imaging, CDFI, and SE of patients with different ages. All the images were split into training and testing datasets by the ratio of 80%:20%. The predictive performance on testing dataset was evaluated through 5 metrics including mean accuracy, precision, recall, F1-scores, and confusion matrix. RESULTS: Based on B-US imaging, the test mean accuracy is 74.50%, the precision is 74.84%, the recall is 72.48%, and the F1-scores is 0.73. By combining B-US imaging with CDFI, the results were increased to 85.41%, 85.03%, 85.05%, and 0.84, respectively. With the integration of B-US imaging and SE, the results were changed to 75.64%, 74.69%, 73.86%, and 0.74, respectively. Using images from patients under 40 years old, the results were 90.48%, 90.88%, 88.47%, and 0.89. When images from patients who are above 40 years old, they were changed to 81.96%, 83.12%, 80.5%, and 0.81, respectively. CONCLUSION: Multimodal ultrasound imaging can be used to accurately predict the molecular subtypes of breast lesions. In addition to B-US imaging, CDFI rather than SE contribute further to improve predictive performance. The predictive performance is notably better for patients under 40 years old compared with those who are 40 years old and above.

RESUMO

BACKGROUND: Robot-assisted radical prostatectomy (RARP) has emerged as a pivotal surgical intervention for the treatment of prostate cancer (PCa). However, the complexity of clinical cases, heterogeneity of PCa, and limitations in physician expertise pose challenges to rational decision-making in RARP. To address these challenges, the authors aimed to organize the knowledge of previously complex cohorts and establish an online platform named the RARP knowledge base (RARPKB) to provide reference evidence for personalized treatment plans. MATERIALS AND METHODS: PubMed searches over the past two decades were conducted to identify publications describing RARP. The authors collected, classified, and structured surgical details, patient information, surgical data, and various statistical results from the literature. A knowledge-guided decision-support tool was established using MySQL, DataTable, ECharts, and JavaScript. ChatGPT-4 and two assessment scales were used to validate and compare the platform. RESULTS: The platform comprised 583 studies, 1589 cohorts, 1 911 968 patients, and 11 986 records, resulting in 54 834 data entries. The knowledge-guided decision support tool provide personalized surgical plan recommendations and potential complications on the basis of patients' baseline and surgical information. Compared with ChatGPT-4, RARPKB outperformed in authenticity (100% vs. 73%), matching (100% vs. 53%), personalized recommendations (100% vs. 20%), matching of patients (100% vs. 0%), and personalized recommendations for complications (100% vs. 20%). Postuse, the average System Usability Scale score was 88.88±15.03, and the Net Promoter Score of RARPKB was 85. The knowledge base is available at: http://rarpkb.bioinf.org.cn . CONCLUSIONS: The authors introduced the pioneering RARPKB, the first knowledge base for robot-assisted surgery, with an emphasis on PCa. RARPKB can assist in personalized and complex surgical planning for PCa to improve its efficacy. RARPKB provides a reference for the future applications of artificial intelligence in clinical practice.

RESUMO

Background: Persistent infection with high-risk human papillomavirus (HR-HPV) can lead to cervical intraepithelial neoplasia and cancer. At present, there is no medication that specifically targets HR-HPV infection. Objective: This study aimed to evaluate the effectiveness of different interventions in promoting HR-HPV regression using a MeSH meta-analysis method. Methods: A search for randomized controlled trials (RCTs) reporting different interventions for the treatment of HR-HPV infection included PubMed, Web of Science, Embase and Cochrane Library from the inception of the databases to March 8, 2023. Two researchers independently screened the articles, extracted data, and evaluated the quality. The literature that met the inclusion criteria was selected, the quality and risk of bias of the included studies were assessed according to the Cochrane 5.1 manual, and NMA was performed using Stata 16.0. The area under the cumulative ranking probability graph (SUCRA) represented the probability that each treatment would be the best intervention. Results: Nine studies involving 961 patients and 7 treatment options were included in the analysis. The results of the network meta-analysis indicated the following rank order in terms of promoting HR-HPV conversion: Anti-HPV biological dressing > vaginal gel > imiquimod > REBACIN® > interferon > probiotics > observation/placebo > Polyphenon E. Conclusion: Anti-HPV biological dressing treatment was found to be significantly effective in promoting HR-HPV conversion. However, further validation of the findings is necessary due to the limited number and quality of studies included in the analysis.

RESUMO

Background: Deep learning methods are increasingly applied in the medical field; however, their lack of interpretability remains a challenge. Captum is a tool that can be used to interpret neural network models by computing feature importance weights. Although Captum is an interpretable model, it is rarely used to study medical problems, and there is a scarcity of data regarding MRI anatomical measurements for patients with prostate cancer after undergoing Robotic-Assisted Radical Prostatectomy (RARP). Consequently, predictive models for continence that use multiple types of anatomical MRI measurements are limited. Methods: We explored the energy efficiency of deep learning models for predicting continence by analyzing MRI measurements. We analyzed and compared various statistical models and provided reference examples for the clinical application of interpretable deep-learning models. Patients who underwent RARP at our institution between July 2019 and December 2020 were included in this study. A series of clinical MRI anatomical measurements from these patients was used to discover continence features, and their impact on continence was primarily evaluated using a series of statistical methods and computational models. Results: Age and six other anatomical measurements were identified as the top seven features of continence by the proposed model UINet7 with an accuracy of 0.97, and the first four of these features were also found by primary statistical analysis. Conclusions: This study fills the gaps in the in-depth investigation of continence features after RARP due to the limitations of clinical data and applicable models. We provide a pioneering example of the application of deep-learning models to clinical problems. The interpretability analysis of deep learning models has the potential for clinical applications.

RESUMO

Flexible strain sensors have significant progress in the fields of human-computer interaction, medical monitoring, and handwriting recognition, but they also face many challenges such as the capture of weak signals, comprehensive acquisition of the information, and accurate recognition. Flexible strain sensors can sense externally applied deformations, accurately measure human motion and physiological signals, and record signal characteristics of handwritten text. Herein, we prepare a sandwich-structured flexible strain sensor based on an MXene/polypyrrole/hydroxyethyl cellulose (MXene/PPy/HEC) conductive material and a PDMS flexible substrate. The sensor features a wide linear strain detection range (0-94%), high sensitivity (gauge factor 357.5), reliable repeatability (>1300 cycles), ultrafast response-recovery time (300 ms), and other excellent sensing properties. The MXene/PPy/HEC sensor can detect human physiological activities, exhibiting excellent performance in measuring external strain changes and real-time motion detection. In addition, the signals of English words, Arabic numerals, and Chinese characters handwritten by volunteers measured by the MXene/PPy/HEC sensor have unique characteristics. Through machine learning technology, different handwritten characters are successfully identified, and the recognition accuracy is higher than 96%. The results show that the MXene/PPy/HEC sensor has a significant impact in the fields of human motion detection, medical and health monitoring, and handwriting recognition.

RESUMO

The rapid development of wearable electronic devices and virtual reality technology has revived interest in flexible sensing and control devices. Here, we report an ionic hydrogel (PTSM) prepared from polypropylene amine (PAM), tannic acid (TA), sodium alginate (SA), and MXene. Based on the multiple weak H-bonds, this hydrogel exhibits excellent stretchability (strain >4600%), adhesion, and self-healing. The introduction of MXene nanosheets endows the hydrogel sensor with a high gauge factor (GF) of 6.6. Meanwhile, it also enables triboelectric nanogenerators (PTSM-TENGs) fabricated from silicone rubber-encapsulated hydrogels to have excellent energy harvesting efficiency, with an instantaneous output power density of 54.24 mW/m2. We build a glove-based human-computer interaction (HMI) system using PTSM-TENGs. The multidimensional signal features of PTSM-TENG are extracted and analyzed by the HMI system, and the functions of gesture visualization and robot hand control are realized. In addition, triboelectric signals can be used for object recognition with the help of machine learning techniques. The glove based on PTSM-TENG achieves the classification and recognition of five objects through contact, with an accuracy rate of 98.7%. Therefore, strain sensors and triboelectric nanogenerators based on hydrogels have broad application prospects in man-machine interface, intelligent recognition systems, auxiliary control systems, and other fields due to their excellent stretchable and high self-healing performance.

RESUMO

Purpose: Prophylactic intravenous nalbuphine was administered to observe its median effective dose (ED50) in reducing pain after undergoing laparoscopic total hysterectomy. To investigate the effect of different doses of nalbuphine on postoperative analgesia and adverse reactions in patients. Patients and Methods: The 120 patients undergoing laparoscopic total hysterectomy were divided into 6 groups: group C (control) and group P (5 different doses of nalbuphine) with 20 patients per group. The doses of nalbuphine in group P were in an equally proportional series (groups P1, P2, P3, P4, and P5 received doses of 0.280, 0.200, 0.140, 0.100, and 0.070 mg/kg, respectively), diluted to 20 mL with saline and administered 5 min before the induction of anesthesia. A similar volume (20 mL) of saline was administered to group C 5 min before the induction of anesthesia. The numeric rating scale (NRS) of patients during awakening and after surgery, the number of postoperative salvage analgesia, and the occurrence of postoperative adverse effects were recorded. Results: The ED50 (95% confidence interval (CI)) of nalbuphine in preventing pain during the awakening period in patients calculated using the point-slope method was 0.125 (0.108, 0.145) mg/kg. NRS scores differed among the 6 groups at 30 min and 1 h after extubation (P < 0.001; P < 0.001). Pairwise comparisons between groups revealed that, at 30 min after extubation, compared with group P1, the NRS scores of groups P4, P5, and C were higher (P = 0.001, P < 0.001, P < 0.001); compared with group P2, groups P5 and C had higher NRS scores (P = 0.011, P = 0.001). At 1 h after extubation, the NRS scores of groups P1 and P2 were lower than that of group P4 (P = 0.046, P = 0.036). Compared with the control, only the group P1 had a lower cough score (P = 0.009) and there were no differences in the other groups. There were no differences in sedation score at 10 min after extubation, the incidence of adverse events at 24 h postoperatively, or the number of remedial analgesics at 24 h postoperatively (P > 0.05). Conclusion: The ED50 (95% CI) of nalbuphine as a prophylactic in reducing pain during recovery was 0.125 (0.108, 0.145) mg/kg. Compared with the control, nalbuphine at doses of 0.140, 0.200, and 0.280 mg/kg prevented pain during the awakening period. Among these doses, 0.280 mg/kg was determined to be the best, the occurrence of cough was less during extubation and the postoperative analgesic effect was good. However, it is necessary to pay attention to the occurrence of adverse reactions.

RESUMO

BACKGROUND: Minimally invasive surgery for carpal tunnel syndrome has been consistently the mainstay of treatment. In this study, we developed a novel bush hook via a mini-transverse incision at proximal wrist crease to surgically treat carpal tunnel syndrome and our aim was to compare the results with those of mid-palmar small longitudinal incision in carpal tunnel release. METHODS: This is a retrospective study on patients who received a mini-transverse incision and a novel bush hook or a mid-palmar small longitudinal incision for treatment of carpal tunnel syndrome. The decision to receive either technique was made mainly based on patients' choice. The clinical results were evaluated at 1 week, 1 month, 3 and 6 months postoperatively and compared. RESULTS: In total, 58 patients in mini-transverse incision group and 74 in mid-palmar longitudinal incision group were include. The follow-up period was 6.8 ± 1.6 months. The mini-transverse incision group had a significantly smaller incision (4.3 ± 0.4 mm vs. 26.2 ± 1.6 mm), shorter surgical time (7.8 ± 2.6 min vs. 19.7 ± 2.8 min), but not for hospital stay (3.2 ± 1.9 vs. 3.6 ± 2.2 days). Both groups showed significant improvement from baseline level at any time points postoperatively (all P < 0.001). At 1 month and 3 months, the mini-transverse incision group showed a significantly better improvement of VAS, SSS and FSS score (P < 0.05). At 6 months, the differences were no longer significant (P > 0.05). In addition, the mini-transverse incision group showed a significantly reduced time to return to the work and activities, tendency to higher rate of excellence and good outcomes and fewer complications. CONCLUSIONS: This novel technique via a mini-transverse incision and bush hook showed better clinical effectiveness and safety, and can be considered as an alternative for wrist tunnel release after the results are validated by higher-level evidence studies. Evidence level: III.

RESUMO

PURPOSE: To estimate the efficacy and safety of ocriplasmin for patients with vitreous macular traction (VMT). METHODS: The PubMed, EMBASE and Ovid were searched up to May 2020 to identify related studies. Statistical analysis was conducted by R software version 3.6.3. Results in proportion with 95% confidence interval (CI) were calculated by means of Freeman-Tukey variant of arcsine square transformation. RESULTS: The pooling results indicated the overall complete release rate was 50% (95% CI [45%-54%]). For VMT patients younger than 65 years old, with smaller adhesion size of VMT (<1500 µm), phakic eyes, with macular hole (MH) and subretinal fluid (SRF), while without epiretinal membrane (ERM), ocriplasmin could achieve much higher complete release rates than those under opposite conditions. The general nonsurgical closure rate of MH was 34% (95% CI [30%-37%]), and it was positively correlated with the MH size. The visual improvement rate was 45% (95% CI [32%-59%]), and it was higher for patients with VMT resolution (59%, 95% CI [41%-75%]). The secondary pars plana vitrectomy (PPV) rate for patients without MH closure or VMT resolution was about 31% (95% CI [23%-39%]). The incidence of MH progression was 10% (95% CI [4%-18%]), and other severe adverse events such as endophthalmitis, retinal detachment and retinal tear were relatively rare. CONCLUSION: Ocriplasmin is an effective, reliable and relatively safe intervention for the treatment of VMT. The most suitable candidates were patients younger than 65 years old, with smaller adhesion size (<1500 µm), phakic eyes, with MH and SRF, while without ERM.

RESUMO

Lignosulfonate (LS) was successfully introduced into the epoxy resin matrix with the aid of ethylene glycol (EG) dissolution. Both the rigid LS and soft EG segments were linked into the cross-linked network structure of epoxy resin via esterification of hydroxyl groups in LS and EG molecules with anhydride. The ultimate properties of cured samples were adjusted effectively by changing the proportion of LS and EG components. Curing reaction and kinetics were analyzed, by which the optimal curing process parameters were determined. Although thermal stability of LS itself was relatively lower than that of neat epoxy, the thermal performance was significantly enhanced for the modified sample of epoxy/LS0.5-EG0.5. At the same time, the flexural strength, flexural modulus and impact strength were found to be increased by 23.1, 35.7 and 15.1% respectively compared with the neat epoxy. In addition, the excellent shape memory behavior and improved mechanical stability with LS addition were exhibited by the cured LS-EG modified specimens. This work reveals that lignin can be used as an efficient functional additive to regulate thermal, mechanical and shape memory properties of epoxy resin.

RESUMO

Paclitaxel (PTX) is successfully loaded by surface modification of distearoyl phosphoethanolamine (DSPE) on halloysite nanotubes (HNTs) with different inner lumen diameters. Drug loading of DSPE-HNTs-PTX attains 18.44% of DSPE content with a nearly complete release (near 100%) achieved. The anticancer efficacy (cell viability less than 52%) of DSPE-HNTs15-PTX increased and is attributed to the lower interfacial energy both inside and outside the tubes that improves tube loading.

RESUMO

PURPOSE: This study aimed to investigate the outcomes of a mini-transverse incision with a bush-hook versus a conventional open incision for carpal tunnel release (CTR). METHODS: This was a prospective study. The decision to receive either technique (mini-transverse incision with a bush-hook or conventional open incision) was primarily based on patients' choice. Patients' symptom severity, functional status, and symptomatic pain were measured at pre-operation, 1 month, and 3 and 6 months postoperatively, and any relevant complications were recorded. Kelly's scale was used to evaluate the overall clinical efficacy. RESULTS: Eighty-nine patients were included in the open CTR group and 85 patients in the mini-transverse incision group. The mini-transverse incision group had a significantly smaller incision (4.4±0.6 vs 44.8±3.7 mm), shorter surgical time (7.8±1.9 vs 21.2±3.4 min), and shorter hospital stay (3.7±1.6 vs 5.9±2.0 days) than did the open CTR group. Both groups showed significant improvements from baseline levels (all P<0.001). At postoperative 1 month and 3 months, the transverse incision group showed a significantly better VAS, SSS, and FSS (all P<0.05), but the difference was non-significant at 6 months except for FSS (P=0.022). Also, mini-transverse incision showed a significantly reduced time to return to work and activities, trend to a higher rate of excellence, and good and fewer complications than did the open CTR. CONCLUSIONS: The mini-transverse incision exhibited better performance in surgery-related measures, symptomatic remission, functional recovery, and postoperative morbidity, thus could be considered a promising technique alternative.

RESUMO

Purpose: The albumin-to-γ-glutamyltransferase ratio (AGR), a novel inflammation-related index, has been reported to have prognostic importance in several malignancies but not yet in gallbladder cancer (GBC). This study intended to assess the prognostic value of AGR in GBC and to develop a nomogram based on AGR for predicting overall survival (OS) in GBC patients after surgery. Methods: Medical records of 140 qualified GBC patients between July 2003 and June 2017 were retrospectively analyzed. The function "surv_cutpoint" in the R package "survminer" was implemented to discover the optimal cut-off value of AGR. A nomogram on the fundamental of Cox model was established in the training cohort and was internally validated using calibration curves, Harrell's concordance index, time-dependent AUC plots and decisive curve analyses. Results: The optimal AGR cut-off value concerning overall survival was 2.050. Univariate and multivariate analyses demonstrated that AGR (HR=0.354, P=0.004), T stage (HR=3.114, P=0.004), R0 resection (HR=0.448, P=0.003), BMI (HR=0.470, P=0.002) and CA19-9 (HR=1.704, P=0.048) were independent predictors for OS. The nomogram combining these prognostic factors showed considerable prognostic performance in term of consistency, discrimination and net benefit. Conclusion: AGR has independent prognostic value for OS in GBC patients receiving surgery. A nomogram incorporating AGR, T stage, R0 resection, CA19-9 and BMI achieved enhanced prognostic ability.

RESUMO

PURPOSE: To estimate the polyp regression rate and treatment prognosis of different interventions for polypoidal choroidal vasculopathy (PCV) and clarify its baseline characteristics. METHODS: The PubMed, EMBASE, and Ovid were searched up to January 2020 to identify related studies. R software version 3.6.3 was used to perform the statistical analyses. Results in proportion with 95% confidence interval (CI) were calculated by means of the Freeman-Tukey variant of arcsine square transformation. Chi-squared test and I2 statistics were used to evaluate the statistical heterogeneity. Sensitivity analysis and subgroup analyses were performed to identify the source of heterogeneity. RESULTS: This meta-analysis included 104 studies with 5816 patients. The pooling results indicated the general rate of complete polyp regression at post-treatment 12 months was 64% (95% CI [57~71%]), 89% (95% CI [81~95%]) for photodynamic therapy (PDT) monotherapy, 78% (95% CI [68~86%]) for PDT plus anti-vascular endothelial growth factor (anti-VEGF), and 42% (95% CI [35~49%]) for anti-VEGF monotherapy; PDT plus anti-VEGF showed the best efficacy in visual improvement and achieved the highest rate of dry macula (91%, 95% CI [78~99%]), while anti-VEGF monotherapy achieved the lowest polyp recurrence rate (14%, 95% CI [8~20%]); PDT monotherapy showed the best efficacy in pigment epithelial detachment regression (66%, 95% CI [58~83%]). Additionally, the baseline characteristics of PCV were also well described. CONCLUSION: PDT plus anti-VEGF is still valuable for the management of PCV; it could achieve not only satisfactory anatomical outcomes like dry macula rate and polyp regression rate but also ideal visual prognosis like BCVA improvement.

RESUMO

PURPOSE: The immune prognostic index (IPI) has been used as a prognostic biomarker in various cancers. However, the prognostic value of the IPI in gallbladder cancer remains to be determined. PATIENTS AND METHODS: This study included 139 patients who were diagnosed with gallbladder cancer after surgical resection from 2003 to 2017. We used a Kaplan-Meier curve analysis to evaluate the overall survival (OS). Cox proportional hazards regression methodology was used to identify significant independent prognostic factors. Prognostic nomograms for predicting OS were established to achieve superior discriminatory abilities. The prognostic nomograms were verified according to the concordance index, calibration curves, and decision curve analyses in the training cohort and validation cohort. RESULTS: Of all 139 patients, 87 (62.6%) patients accepted R0 resection, 32% and 68% were stratified into the good and poor IPI group, respectively. The median OS was 55.9 (range, 5.93-182.7) months in the good IPI group and 15.47 (range, 0.29-190.37) months in the poor IPI group (P < 0.001). In the multivariate Cox model, the IPI was an independent predictor of OS along with the CA19-9, curative resection, and postoperative chemoradiotherapy. A nomogram based on these factors was efficient in predicting 1-, 3-, and 5-year survival probabilities. The nomogram showed higher sensitivity and specificity than the current cancer TNM staging system in the training cohort and validation cohort. CONCLUSION: The IPI is an independent prognostic factor in gallbladder cancer. Our IPI-based nomogram can serve as a useful and convenient prognostic tool for gallbladder cancer.

RESUMO

Currently, controversies regarding the optimal time-point of anti-vascular endothelial growth factor (VEGF) pretreatment before pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR) still exist. To clarify this, we conducted a network meta-analysis, 26 randomized controlled trials including 1806 PDR patients were included. Compared with the sham group, performing anti-VEGF injection at preoperative (Pre-Op) 6 to 14 days could significantly improve post-operative best-corrected visual acuity (BCVA) and decrease the incidence of recurrent vitreous hemorrhage (VH). Meanwhile, it could significantly reduce the duration of surgery. Performing anti-VEGF injection at Pre-Op more than 14 days, 6 to 14 days or 1 to 5 days could significantly reduce the incidence of intra-operative bleeding, while no significant benefit existed at the end of PPV (P > 0.05). No significant difference existed between all those strategies and sham group in reducing the rate of silicone oil tamponade. Based on currently available evidence, performing the anti-VEGF pretreatment at pre-operative 6 to 14 days showed best efficacy in improving post-operative BCVA, reducing the duration of surgery and incidence of recurrent VH, it also achieves satisfactory effect in reducing the incidence of intra-operative bleeding.
