A prospective cohort study was conducted to determine the incidence and risk factors of symptomatic venous thromboembolism (sVTE) during the perioperative period in patients with malignant bone and soft tissue tumors.
Patients with newly diagnosed primary malignant bone and soft tissue tumors for whom definitive surgery was planned were consecutively registered among 27 tertiary hospitals specializing in musculoskeletal oncology. Clinicopathological information on each patient was collected prospectively, and careful follow-up was conducted for 6months after surgery. The study endpoint was the occurrence of sVTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE).
Eleven of 929 patients developed sVTE, including 8 patients with DVT, 2 with PE, and 1 with both, making the incidence of sVTE 1.18%. The median time until the development of sVTE after tumor resection was 11days, ranging from - 7 to 95days. Multiple logistic regression analyses revealed that ischemic heart disease as a comorbidity, maximum tumor diameter exceeding 8cm, and elevated preoperative platelet count were independent risk factors for sVTE.
The incidence of sVTE in this series of patients with bone and soft tissue sarcomas was 1.18%, which was relatively lower than in previous retrospective studies. We identified the risk factors for sVTE specific to patients with malignant bone and soft tissue tumors, and these included ischemic heart disease, tumor size, and elevation of the preoperative platelet count.

Morbidity and in-hospital mortality rates of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in Germany are not known.
From 2009 to 2018 all patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in Germany were retrospectively analyzed regarding morbidity and in-hospital mortality rates according to nationwide hospital billing data based on diagnosis-related groups (DRG). The "failure to rescue" (FTR) index, characterizing patients who died after severe but potentially manageable complications, was calculated.
In total, 8463 patients were included and analyzed. Female sex predominated (1.51). Colonic origin of peritoneal metastasis was highest throughout all years, reaching its highest level in 2017 (55%; n = 563) and its lowest level in 2012 (40%; n = 349). Median length of hospital stay reached its maximum in 2017 at 23.9days and its minimum in 2010 at 22.0days. Analysis of the total FTR index showed a noticeable improvement over the years, reaching its lowest values in 2017 (9.8%) and 2018 (8.8%). The FTR index for sepsis, peritonitis, and pulmonary complications significantly improved over time. Of the 8463 included patients, 290 died during hospital stay, reflecting an in-hospital mortality rate of 3.4%.
In-hospital mortality after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is reasonably low compared with other surgical procedures. The improvement in the FTR index reflects efforts to centralize treatment at specialized high-volume centers.

To calculate the diagnostic accuracy of nipple aspirate fluid (NAF) cytology.
Evaluation of NAF cytology in asymptomatic patients conceptually offers a non-invasive method for either screening for breast cancer or else predicting or stratifying future cancer risk.
Studies were identified by performing electronic searches up to August 2019. A meta-analysis was conducted to attain an overall pooled sensitivity and specificity of NAF for breast cancer detection.
A search through 938 studies yielded a total of 19 studies. Overall, 9308 patients were examined, with cytology results from 10,147 breasts [age (years), mean ± SD = 49.73 ± 4.09years]. Diagnostic accuracy meta-analysis of NAF revealed a pooled specificity of 0.97 (95% CI 0.97-0.98), and sensitivity of 0.64 (95% CI 0.62-0.66).
The diagnostic accuracy of nipple smear cytology is limited by poor sensitivity. If nipple fluid assessment is to be used for diagnosis, then emerging technologies for fluid biomarker analysis must supersede the current diagnostic accuracy of NAF cytology.

Chemoradiation (CT/RT) followed by radical surgery (RS) may play a role in locally advanced cervical cancer (LACC) patients with suboptimal response to CT/RT or in low-income countries with limited access to radiotherapy. Our aim is to evaluate oncological and surgical outcomes of minimally invasive radical surgery (MI-RS) compared with open radical surgery (O-RS).
Data for stage IB2-IVA cervical cancer patients managed by CT/RT and RS were retrospectively analyzed.
Beginning with 686 patients, propensity score matching resulted in 462 cases (231 per group), balanced for FIGO stage, lymph node status, histotype, tumor grade, and clinical response to CT/RT. The 5-year disease-free survival (DFS) was 73.7% in the O-RS patients and 73.0% in the MI-RS patients (HR 1.034, 95% CI 0.708-1.512, p = 0.861). The 5-year locoregional recurrence rate was 12.5% (O-RS) versus 15.2% (MI-RS) (HR 1.174, 95% CI 0.656-2.104, p = 0.588). The 5-year disease-specific survival (DSS) was 80.4% in O-RS patients and 85.3% in the MI-RS group (HR 0.731, 95% CI 0.438-1.220, p = 0.228). Estimated blood loss was lower in the MI-RS group (p < 0.001), as was length of hospital stay (p < 0.001). Early postoperative complications occurred in 77 patients (33.3%) in the O-RS group versus 88 patients (38.1%) in the MI-RS group (p = 0.331). Fifty-six (24.2%) patients experienced late postoperative complications in the O-RS group, versus 61 patients (26.4%) in the MI-RS group (p = 0.668).
MI-RS and O-RS are associated with similar rates of recurrence and death in LACC patients managed by surgery after CT/RT. No difference in early or late complications was reported.

Gastrointestinal cancer surgery patients often develop perioperative anemia commonly treated with red blood cell (RBC) transfusions. Given the potential associated risks, evidence published over the past 10years supports restrictive transfusion practices and blood conservation programs. Whether transfusion practices have changed remains unclear. see more We describe temporal RBC transfusion trends in a large North American population who underwent gastrointestinal cancer surgery.
We conducted a population-based retrospective cohort study of patients who underwent gastrointestinal cancer resection between 2007 and 2018 using health administrative datasets. The outcome was RBC transfusion during hospitalization. Temporal transfusion trends were analyzed with Cochran-Armitage tests. Multivariable regression assessed the association between year of diagnosis and likelihood of RBC transfusion while controlling for confounding.
Of 79,764 patients undergoing gastrointestinal cancer resection, the median age was 69yearsgoing gastrointestinal cancer resection. This information provides a foundation to further examine transfusion appropriateness or explore if additional transfusion minimization in surgical patients can be achieved.From a holistic point of view, aging results from the cumulative erosion of the various systems. Among these, the immune system is interconnected to the rest as immune cells are present in all organs and recirculate through bloodstream. Immunosenescence is the term used to define the remodelling of immune changes during aging. Because immune cells-and particularly lymphocytes-can further differentiate after their maturation in response to pathogen recognition, it is therefore unclear when senescence is induced in these cells. Additionally, it is also unclear which signals triggers senescence in immune cells (i) aging per se, (ii) specific response to pathogens, (iii) underlying conditions, or (iv) inflammaging. In this review, we will cover the current knowledge and concepts linked to immunosenescence and we focus this review on lymphocytes and T cells, which represent the typical model for replicative senescence. With the evidence presented, we propose to disentangle the senescence of immune cells from chronological aging.Testing gluten content in food, before it reaches the consumer, becomes a major challenge where cross-contamination during processing and transportation is a very common occurrence. In this study, a microfluidic electrochemical aptasensing system for the detection of gliadin has been proposed. The fabrication of the sensor involves its modification by using a combination of 2D nanomaterial molybdenum disulfide (MoS2)/graphene with the addition of gold (Au) nanoparticles. Aptamers, a short string of nucleotide bases that are very specific to gliadin, were used in this sensor as the biomarker. The electrochemical standard reduction potential of the ferro-ferricyanide indicator was found to be ~ 530 mV. This setup was integrated with a unique polydimethylsiloxane (PDMS)-based flexible microfluidic device for sample enrichment and portability. The results of this sensor show that the limit of detection was 7 pM. The total sample assay time was 20 min and a good linear range was observed from 4 to 250 nM with an R2 value of 0.982. Different flour samples sourced from the local market were tested and interfering molecules were added to ensure selectivity. The study shows promise in its applicability in real-time gliadin detection.Graphical abstract.BRAF and MEK inhibitor combination therapy is the standard treatment for patients with BRAF V600E mutant metastatic melanoma. Neutrophilic panniculitis is a known rare complication of BRAF inhibitor therapy and can act as a potential mimic of melanoma metastases on 18F-FDG PET/CT. In this case series, we present three cases of BRAF inhibitor-induced panniculitis in patients being treated for BRAF-mutant metastatic melanoma and emphasize the use of ultrasound to differentiate between panniculitis lesions, which are typically ill-defined echogenic masses and subcutaneous soft tissue melanoma metastases, which present as hypoechoic vascular masses.The spine is the main stabilizer and load bearer of the axial skeleton. It is also important for the protection of neural structures, such as the spinal cord, nerve roots, and cauda equina. In the healthy skeleton, most injuries are a consequence of high-energy trauma and can lead to severe dysfunction, such as tetraplegia or paraplegia. In order to avoid such disabilities, it is important to recognize details that will guide treatment, and that will determine the necessity or not to have surgery. Familiarity with radiography, CT, and MRI in evaluating spine trauma is necessary, as, in some cases, all three methods will be useful in determining management and surgical planning. The most important factor in determining management in the thoracolumbar spine is the posterior ligamentous complex (PLC). Therefore, familiarity with its anatomy, primary and secondary signs of its injuries, is essential for radiologists in the emergency setting. Spine fractures are a very heterogeneous group of disorders. Management can be both conservative and surgical.
