Background
We have previously demonstrated that implementing an enhanced recovery protocol (ERP) improved outcomes after esophagectomy. We sought to examine if, after a decade of an established ERP, ...further improvements in postoperative outcomes could be made after continually optimizing and revising the pathway.
Methods
Patients undergoing esophagectomy for cancer from January 2019 to January 2020 were compared with our early-experience group within the initial ERP (June 2010–May 2011) and pre-ERP traditional care (June 2009–May 2010). The original ERP was initiated on June 2010 and underwent several revisions from 2014 to 2018, incorporating the following, amongst other elements: shorten the planned length of stay from 7 to 6 days, elimination of nasogastric tubes, use of soft closed-suction chest drains, and increased application of minimally invasive esophagectomy (MIE). Thirty-day outcomes (complications, length of stay, readmission) were compared for patients undergoing esophagectomy during the initial and most recent ERPs.
Results
Overall, 175 patients were identified; 47 underwent esophagectomy before ERP implementation (traditional care), 59 patients underwent esophagectomy after implementation of the original ERP, and 69 patients underwent esophagectomy after the most recent ERP (ERP 2.0). The groups were similar with respect to age, sex, and diagnosis. There were three times more MIEs in the ERP 2.0 group with a shorter median length of stay (7 6–9 vs. 8 7–17 vs. 10 9–17;
p
< 0.001) without impacting postoperative morbidity or readmission rate.
Conclusion
Continued evaluation of institutional outcomes after esophagectomy should be performed to identify target areas for optimization and revision of established enhanced recovery protocols. ERPs are dynamic processes that can be further refined to yield greater improvements in outcomes.
This study investigated the role of the neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak (AL) after esophagectomy for esophageal adenocarcinoma.
This is a retrospective analysis of ...a prospectively collected database from the McGill University Health Center. Included were all patients with esophageal adenocarcinoma who underwent esophagectomy between 2005 and 2016. Patients with chronic infections, concurrent active malignancies, and autoimmune conditions were excluded. NLR values were obtained on postoperative days (POD) 0, 1, 2, and 3. Receiver operating characteristic curve study and multivariable logistic analysis were conducted to evaluate the diagnostic value of NLR.
The study included 330 patients, and AL developed in 16%. Mean NLR values on POD1, 2, and 3 were higher in patients with leaks (20 vs 14 on POD1, P < .001; 20 vs 12 on POD2, P < .001; and 19 vs 10 on POD3, P < .001). The NLR value on POD3 was associated with an area under the curve of 70% and a negative predictive value of 92.4%. Multivariable analyses identified higher American Society of Anesthesiologists Physical Status Classification, increasing NLR trend (between POD1 and POD3), POD1 NLR, POD2 NLR, and POD3 NLR as independent factors associated with AL.
Patients who developed AL demonstrate higher mean NLR values in the early postoperative period with rising trends. Conversely a low NLR is associated with a high negative predictive value for AL. This simple metric allows risk stratification that may guide treatment decisions in esophagectomy patients.
The search for other indicators to assess the weight status of individuals is important as it may provide more accurate information and assist in personalized medicine.This work is aimed to develop a ...machine learning predictions of weigh status derived from bioimpedance measurements and other physical parameters of healthy infant juvenile cohort from the Southern Cuba Region, Santiago de Cuba.
The volunteers were selected between 2002 and 2008, ranging in age between 2 and 18 years old. In total, 393 female and male infant and juvenile individuals are studied. The bioimpedance parameters are obtained by measuring standard tetrapolar whole-body configuration. A classification model are performed, followed by a prediction of other bioparameters influencing the weight status.
The results obtained from the classification model indicate that fat-free mass, reactance, and corrected resistance primarily influence the weight status of the studied population. Specifically, the regression model demonstrates that other bioparameters derived from impedance measurements can be highly accurate in estimating weight status.
The classification and regression predictive models developed in this work are of the great importance for accessing to the weigh status with high accuracy of younger individuals at the Oncological Hospital in Santiago de Cuba, Cuba.
The search for other indicators to assess the weight and nutritional status of individuals is important as it may provide more accurate information and assist in personalized medicine. This work is ...aimed to develop a machine learning predictions of weigh status derived from bioimpedance measurements and other physical parameters of healthy younger volunteers from Southern Cuba Region.
A pilot random study at the Pediatrics Hospital was conducted. The volunteers were selected between 2002 and 2008, ranging in age between 2 and 18 years old. In total, 776 female and male volunteers are studied. Along the age and sex in the cohort, volunteers with class I obesity, overweight, underweight and with normal weight are considered. The bioimpedance parameters are obtained by measuring standard tetrapolar whole-body configuration. The bioimpedance analyser is used, collecting fundamental bioelectrical and other parameters of interest. A classification model are performed, followed by a prediction of the body mass index.
The results derived from the classification leaner reveal that the size, body density, phase angle, body mass index, fat-free mass, total body water volume according to Kotler, body surface area, extracellular water according to Kotler and sex largely govern the weight status of this population. In particular, the regression model shows that other bioparameters derived from impedance measurements can be associated with weight status estimation with high accuracy.
The classification and regression predictive models developed in this work are of the great importance to assist the diagnosis of weigh status with high accuracy. These models can be used for prompt weight status evaluation of younger individuals at the Pediatrics Hospital in Santiago de Cuba, Cuba.
Surgery, as part of a multimodal approach, offers the greatest chance of cure for esophageal cancer. However, esophagectomy is often perceived as having a lasting impact on quality of life (QOL), ...biasing some physicians and patients toward nonoperative management. A comprehensive understanding of the dynamic changes in patient-centered outcomes is therefore important for decision making. Our objective was to determine the long-term QOL after esophagectomy.
Data were obtained from a prospectively collected (2006-2015) esophagectomy database at a high-volume center, and patients surviving 3 or more years were identified. Health-related QOL was evaluated using the Functional Assessment of Cancer Therapy-Esophageal Module (FACT-E) at diagnosis and every 3 to 6 months, and was stratified according to operative approach, stage, and complications. In addition, QOL scores were compared with normative population values.
Of 480 patients, 47% (n = 226) survived 3 or more years and 70% (158 of 226) completed the health-related QOL assessments. Time of follow-up was 5.1 ± 2.8 years. After a reduction at 1 to 3 months, FACT-E increased from a baseline of 126 (95% CI, 121-131) to 133 (95% CI, 127-139) at 12 months, and to 147 (95% CI, 142-153) by 5 years. There was no difference in long-term FACT-E with respect to the surgical approach, clinical and pathologic stage, or postoperative complications. At long-term follow-up (more than 3 years), QOL did not differ significantly from the normative population reference values.
The long-term QOL of esophagectomy patients surviving at least 3 years is improved when compared with the time of diagnosis and does not differ from the general population.
•Humoral serological response with some vaccines is still unknown in liver transplant recipients.•A higher humoral response was seen with BNT162b2 and mRNA-1273.•Humoral response was 76.9% ...(CoronaVac), 55.6% (Ad5-nCov) and 68.2% (Gam-COVID-Vac) in OLT.
The safety and efficacy data of the different types of available vaccines is still needed. The goal of the present analysis was to evaluate the humoral response to the COVID-19 vaccines in orthotopic liver transplant (OLT) recipients.
Participants were included from February to September 2021. No prioritized vaccination roll call applied for OLT patients. Controls were otherwise healthy people. Blood samples were drawn after 15 days of the complete vaccine doses. The samples were analyzed according to the manufacturer's instructions using the Liaison XL platform from DiaSorin (DiaSorin S.p.A., Italy), and SARS-COV-2 IgG II Quant (Abbott Diagnostics, IL, USA).
A total of 187 participants (133 OLT, 54 controls, median age: 60 years, 58.8% women) were included for the analysis; 74.3% had at least one comorbidity. The serologic response in OLT patients was lower than in controls (median 549 AU/mL vs. 3450 AU/mL, respectively; p = 0.001). A positive humoral response was found in 133 OLT individuals: 89.2% with BNT162b2 (Pfizer-BioNTech), 60% ChAdOx1 nCOV-19 (Oxford-AstraZeneca), 76.9% with CoronaVac (Sinovac, Life Sciences, China), 55.6% Ad5-nCov (Cansino, Biologics), 68.2% Gam-COVID-Vac (Sputnik V) and 100% with mRNA-1273. In controls the serological response was 100%, except for Cansino (75%). In a multivariable model, personal history of COVID-19 and BNT162b2 inoculation were associated with the serologic response, while the use of prednisone (vs. other immunosuppressants) reduced this response.
The serologic response to COVID-19 vaccines in OLT patients is lower than in healthy controls. The BNT162b2 vaccine was associated with a higher serologic response.
Background: Reduced muscle strength (dynapenia) and mass (atrophy) are prognostic factors in oncology. Measuring maximal handgrip strength with dynamometers is feasible but limited by the cost of the ...reference device (JAMAR). Methods: A cross-sectional study was conducted on colorectal cancer outpatients treated with chemotherapy or under active surveillance in our center from September 2022 to July 2023. Accuracy, reliability, and concordance were compared for two handheld dynamometers: the JAMAR Plus (the gold-standard device) and the Camry EH101 (a low-cost index device). A simultaneous nutritional diagnosis with GLIM criteria and bioelectrical impedance analysis (BIA) was carried out. Results: A total of 134 participants were included. The median of maximal strength for the JAMAR Plus had a non-significant difference of 1.4 kg from the Camry EH101. The accuracy and reliability of the devices were high. Bland–Altman analysis showed a 0.8 kg bias and −4.1 to 5.6 kg limits of agreement (LoA); a 0.1 kg bias and −5.3 to 5.4 kg LoA in men; a 1.5 kg bias and −2.2 to 5.3 kg LoA in women. In total, 29.85% of the participants were malnourished. Prevalence of dynapenia increased from 3.67% with the JAMAR Plus to 5.14% with the Camry EH101. Both devices had a moderate and significant correlation with BIA-estimated muscle mass. Conclusions: The Camry EH101 was a cost-effective alternative to JAMAR Plus in our sample.
•Tideglusib is a GSK-3β inhibitor and enhances expression of active β−catenin.•Localized tideglusib promoted new bone formation via increased osteoblastic differentiation.•Early treatment did not ...interfere with precursor cells recruitment and commitment.•The wnt signaling pathway may have a fundamental different role during intramembranous repair.
The Wnt/β-catenin signaling pathway is critical for bone differentiation and regeneration. Tideglusib, a selective FDA approved glycogen synthase kinase-3β (GSK-3β) inhibitor, has been shown to promote dentine formation, but its effect on bone has not been examined. Our objective was to study the effect of localized Tideglusib administration on bone repair. Bone healing between Tideglusib treated and control mice was analysed at 7, 14 and 28 days postoperative (PO) with microCT, dynamic histomorphometry and immunohistology. There was a local downregulation of GSK-3β in Tideglusib animals, resulting in a significant increase in the amount of new bone formation with both enhanced cortical bone bridging and medullary bone deposition. The bone formation in the Tideglusib group was characterized by early osteoblast differentiation with down-regulation of GSK-3β at day 7 and 14, and higher accumulation of active β-catenin at day 14. Here, for the first time, we show a positive effect of Tideglusib on bone formation through the inactivation of GSK-3β. Furthermore, the findings suggest that Tideglusib does not interfere with precursor cell recruitment and commitment, contrary to other GSK-3β antagonists such as lithium chloride. Taken together, the results indicate that Tideglusib could be used directly at a fracture site during the initial intraoperative internal fixation without the need for further surgery, injection or drug delivery system. This FDA-approved drug may be useful in the future for the prevention of non-union in patients presenting with a high risk for fracture-healing.
Recent research has opened new alternatives to traditional chemotherapy treatments using nanomaterials as cytotoxic agents. Anti-cancer nanomedicines do not require specific target sites on key ...proteins or genes to kill cancer cells and have radically different mechanisms to interact with the living matter. Among 1D nanomaterials, multiwalled carbon nanotubes (MWCNTs) have the intrinsic ability to bind tubulin and interfere with microtubule dynamics, mimicking the effect of traditional cytotoxic microtubule-binding agents such as paclitaxel (taxol®). Here, we review the cytotoxic properties of MWCNTs and show a direct pro-apoptotic effect of these nanomaterials in vitro in different cancer cell lines and tumor cells obtained from surgical specimens. Understanding the bio-synthetic relationship between MWCNTs and microtubules could serve to improve these nanomaterials to be used as broad spectrum antineoplastic agents in combination to traditional microtubule-binding treatments, thus avoiding drug resistance mechanisms in cancer cells.
To examine the association between household food insecurity and overweight, obesity and abdominal obesity in Mexican adults.
Cross-sectional study.
We analysed data from the Mexican Halfway National ...Health and Nutrition Survey 2016, a nationally representative survey that accounted for rural and urban areas in four regions of Mexico: North, Centre, Mexico City and South.
Adults from 20 to 59 years old (n 5456, which represents 45 804 210 individuals at the national level).
70·8 % of the Mexican adults had some degree of household food insecurity. This situation showed larger proportions (P < 0·05) among indigenous people, those living in a rural area, in the Southern region or the lowest socio-economic quintiles. The prevalence of obesity and abdominal obesity was higher in female adults (P < 0·001), with the highest proportions occurring among those experiencing severe household food insecurity. Among women, mean BMI and waist circumference were higher as household food insecurity levels increased (P < 0·001). According to multivariate logistic regression models, severe household food insecurity showed to be positively associated with obesity (OR: 2·36; P = 0·001) in Mexican adult females.
Our findings confirm the association between household food insecurity and obesity among Mexican women. Given the socio-demographic characteristics of the food-insecure population, it is alarming that prevailing socio-economic inequalities in the country might also be contributing to the likelihood of obesity. Therefore, it is crucial to maintain and bolster surveillance systems to track both problems and implement adequate policies and interventions.
