To evaluate the diagnostic value of computer-aided diagnosis (CAD) software on ultrasound in distinguishing benign and malignant breast masses and avoiding unnecessary biopsy.

This prospective, multicenter study included patients who were scheduled for pathological diagnosis of breast masses between April 2019 and November 2020. Ultrasound images, videos, CAD analysis, and BI-RADS were obtained. The AUC, accuracy, sensitivity, specificity, PPV, and NPV were calculated and compared with radiologists.

Overall, 901 breast masses in 901 patients were enrolled in this study. The accuracy, sensitivity, specificity, PPV and NPV of CAD software were 89.6%, 94.2%, 87.0%, 80.4%, and 96.3, respectively, in the long-axis section; 89.0%, 91.4%, 87.7%, 80.8%, and 94.7%, respectively, in the short-axis section. With BI-RADS 4a as the cut-off value, CAD software has a higher AUC (0.906 vs 0.734 vs 0.696, all p < 0.001) than both experienced and less experienced radiologists. With BI-RADS 4b as the cut-off value, CADials.gov (NCT03887598) KEY POINTS • Prospective multicenter study showed that computer-aided diagnosis software provides greater diagnostic confidence for differentiating benign and malignant breast masses. • Computer-aided diagnosis software can help radiologists reduce unnecessary biopsy. • The management of patients with breast masses becomes more appropriate.

To investigative the performance of intratumoral and peritumoral radiomics based on contrast-enhanced spectral mammography (CESM) to preoperatively predict the effect of the neoadjuvant chemotherapy (NAC) of breast cancers.

A total of 118 patients with breast cancer who underwent preoperative CESM and NAC from July 2017 to June 2020 were retrospectively analyzed, and the patients were grouped into training (n= 81) and test sets (n= 37) according to the CESM examination time. NAC effect for each patient was assessed by pathology. Intratumoral and peritumoral radiomics features were extracted from CESM images, and feature selection was performed through the Mann-Whitney U test and least absolute shrinkage and selection operator regression (LASSO). Five radiomics signatures based on intratumoral regions, 5-mm peritumoral regions, 10-mm peritumoral regions, intratumoral regions + 5-mm peritumoral regions, and intratumoral regions + 10-mm peritumoral regions were calculated through a linear combination of sele breast cancer.

To distinguish benign from malignant cystic renal lesions (CRL) using a contrast-enhanced CT-based radiomics model and a clinical decision algorithm.

This dual-center retrospective study included patients over 18years old with CRL between 2005 and 2018. The reference standard was histopathology or 4-year imaging follow-up. Training and testing datasets were acquired from two institutions. Quantitative 3Dradiomics analyses were performed on nephrographic phase CT images. Ten-fold cross-validated LASSO regression was applied to the training dataset to identify the most discriminative features. A logistic regression model was trained to classify malignancy and tested on the independent dataset. Reported metrics included areas under the receiver operating characteristic curves (AUC) and balanced accuracy. Decision curve analysis for stratifying patients for surgery was performed in the testing dataset. A decision algorithm was built by combining consensusradiological readings ofBosniak categories and radiomicrformed the management guidelines based on the Bosniak classification for stratifying patients to surgical ablation or active surveillance.

• The radiomics model achieved excellent diagnostic performance in identifying malignant cystic renal lesions in an independent testing dataset (AUC = 0.96). • The machine learning-enhanced decision algorithm outperformed the management guidelines based on the Bosniak classification for stratifying patients to surgical ablation or active surveillance.

Radiosynoviorthesis (RSO) is anuclear medical local treatment modality for inflammatory joint diseases. It is indicated in patients with rheumatoid arthritis (RA) in joints with persistent synovitis despite adequate pharmacotherapy. Arthritis of the elbow joint occurs in up to2/3 of patients with RA. Intra-articular radiotherapy using the beta emitter [

Re] rhenium sulfide leads to sclerosis of the inflamed synovial membrane with subsequent pain alleviation. The clinical efficacy in cubital arthritis, however, has so far only been described in small monocentric studies.

The degree of pain alleviation by RSO was analyzed in patients with rheumatoid cubital arthritis, treated in several nuclear medical practices specialized in RSO.

The subjective pain intensity before and after RSO was documented in atotal of 107patients with rheumatic cubital arthritis using a10-step numeric rating scale (NRS). Adifference of ≥ -2 is rated as asignificant improvement. Follow-up examinations were done after amean interval of 14months after RSO (at least 3months, maximum 50months).

The mean NRS value was 7.3 ± 2.1 before RSO and 2.8 ± 2.2 after RSO. Asignificant pain alleviation was seen in 78.5% of all patients treated. The subgroup analysis also showed asignificant improvement in the pain symptoms in all groups depending on the time interval between the RSO and the control examination. Asignificant pain progression was not observed. The degree of pain relief was independent of the time of follow-up.

Using RSO for local treatment of rheumatoid cubital arthritis leads to asignificant and long-lasting pain relief in more than ¾ of the treated patients.

Umbilical midline incisions for single incision- or reduced port laparoscopic surgery are still discussed controversially because of a higher rate of incisional hernia compared to conventional laparoscopic techniques. The aim of this study was to evaluate incidence and risk factors for incisional hernia after reduced port colorectal surgery.

A total 241 patients underwent elective reduced port colorectal surgery between 2014 and 2020. Follow-up was achieved through telephone interview or clinical examination. The study collective was examined using univariate and multivariate analysis.

A total of 150 patients with complete follow-up were included into this study. Mean follow-up time was 36 (IQR 24-50) months. The study collective consists of 77 (51.3%) female and 73 (48.7%) male patients with an average BMI of 26kg/m

(IQR 23-28) and an average age of 61 (± 14). Leptomycin B mw Indication for surgery was diverticulitis in 55 (36.6%) cases, colorectal cancer in 65 (43.3%) patients, and other benign reasons in 30 (20.0%) cases. An incisional hernia was observed 9 times (6.0%). Obesity (OR 5.8, 95% CI 1.5-23.1, p = 0.02) and pre-existent umbilical hernia (OR 161.0, 95% CI 23.1-1124.5, p < 0.01) were significant risk factors for incisional hernia in the univariate analysis. Furthermore, pre-existent hernia is shown to be a risk factor also in multivariate analysis.

We could demonstrate that reduced port colorectal surgery using an umbilical single port access is feasible and safe with a low rate of incisional hernia. Obesity and pre-existing umbilical hernia are significant risk factors for incisional hernia.

Injury remains an important cause of death and disability globally, with 95% of all childhood injury deaths occurring in low- and lower-middle-income countries (LMICs). Pediatric trauma training, tailored to the resources in LMICs, represents an opportunity to improve such outcomes. We explored the nature of course offerings in pediatric trauma in resource-limited settings.

Seven databases were interrogated up to June 12, 2020, to retrieve articles examining pediatric trauma training in LMICs, as defined by the World Bank, without language restrictions. Independent authors reviewed and selected abstracts based on set criteria. Data from included studies was extracted and analyzed. An adapted Critical Appraisal Skills Programme checklist designed for cohort studies was used to assess the risk of bias.

After screening 3960 articles for eligibility, 16 were included for final analysis. Course delivery methods included didactic modules, simulations, clinical mentorship, small group discussion, audits, assesiatric trauma are not a widespread reality in low-and-middle-income countries. The development of accessible and efficient pediatric trauma education programs is critical for improving pediatric trauma quality of care.Paclitaxel is often excluded during pregnancy for women with breast cancer due to limited neonatal follow-up. We confirmed in utero fetal Paclitaxel exposure for 8 newborns. Birth details and follow-up to 36 months of age is reported. Meconium samples from newborns exposed to chemotherapy were screened by liquid chromatography-high resolution mass spectrometry while blinded to maternal treatment during pregnancy. Newborn information at birth and annually was obtained. Mean gestational age (GA) at cancer diagnosis and start of chemotherapy was 8.7 + 6.2 weeks and 17.1 ± 3.5 weeks. Paclitaxel was started at a mean GA of 27.0 ± 5.8 weeks. Paclitaxel followed Doxorubicin/Cyclophosphamide in 6 cases, 5-Fluouracil/Doxorubicin/Cyclophosphamide in 1, and was used alone in 1. Mean number of days between Paclitaxel and birth was 23 ± 15. Identification of Paclitaxel and/or metabolites was made in all meconium from paclitaxel-exposed fetuses. Birthweight was 

Up to 3years of age, follow-up of neonates exposed to Paclitaxel in utero is reassuring. Continued observation of neonatal development is essential.

• Chemotherapy during the second and third trimester of pregnancy does not result in an increase in congenital malformations or developmental delay. • In non-human primate studies by Van Calsteren et al., variable plasma and/or tissue concentrations of taxanes, carboplatin, and trastuzumab were encountered in the fetal compartment. • Pilot data reported by the current investigators proved that paclitaxel crosses the human placenta.

• This current article provides medical and developmental follow up on the newborns from this exposure for 3 years after birth.

Retrospective study including 84 neonates ≥ 36 weeks of gestational age with HIE and TH with SEPs performed in the first 14 days of life. SEPs from the median nerve were performed after completion of TH. Either unilateral or bilateral absence of N20, or unilateral or bilateral latency ≥ 36 ms, was considered pathological. All newborns underwent a cerebral resonance imaging (MRI) at between days 7 and 14 of life and a neurodevelopmental evaluation using the Brunet-Lezine test at two years of age; a global Brunet-Lezine test score 

The present study demonstrates the good predictive capacity of SEPs performed in the first two weeks of life in newborns with HIE and TH to detect an increased risk of neuroimaging lesions and neurodevelopmental impairment at two years of age.

• Bilateral absence of the N20 cortical component of somatosensory evoked potentials has been associated with poor neurological outcome in neonates with hypoxic-ischemic encephalopathy.
