After consensus of relevant genes and optimization of quality parameters the overall concordance rose to 85.57% in the second cross-validation round. We show that a diagnostic network with harmonized next-generation sequencing analysis and reporting in seven experienced laboratories is feasible in the context of a scientific group. This cooperative nationwide strategy provides advanced molecular diagnostic for acute myeloid leukemia patients of the PETHEMA group.
In the surgical scenario, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion worldwide entails on one end the need to continue to perform surgery at least in case of emergency or oncologic surgery, in patients with or without COrona Virus Disease 2019 (COVID-19), and on the other hand, to avoid the pandemic diffusion both between patients and medical and nursing team. Aim is to report our surgical management protocol during the COVID-19 pandemic in an Italian non-referral center.
Data retrieved during the outbreak for the COVID-19 pandemic, from March 8 to May 4, 2020 (study period) were analyzed and compared to data obtained during the same period in 2019 (control period).
During the study period 41 surgical procedures (24 electives, 17 emergency surgical procedures) underwent surgery in comparison to 99 procedures in the control period. selleck chemicals llc Stratified procedures in elective and emergency surgery, and based on the indication for surgery, the only statistically significant difference was observed in the elective surgery regarding the abdominal wall surgery (0 vs. 13 procedures, p=0.0339). Statistically significant differences were not observed regarding the colorectal and the breast oncologic surgery. All stuff members were COVID-19 free.
The present protocol proved to be safe and useful to prevent SARS-CoV-2 infection before and after surgery for both patients and stuff. The pandemic was responsible for the reduction in number of procedures performed, anyway for the oncologic surgery a statistically significant volume reduction in comparison to 2019 was not observed.

The COVID-19 epidemic became a challenge for Emergency Departments (ED) and a remarkable reduction in surgical emergencies has been widely noticed. Aim of the present study was to evaluate the impact of the pandemic period in the need of surgical emergencies.
Between January 1st and May 31st 2020 all the consecutive general surgery emergencies performed by the Careggi University hospital emergency surgery unit were prospectively recorded and compared to the same period of 2019. Demographic and clinical data were recorded and analyzed.
The number of surgical procedures decreased only in the month of March 2020 (compared to 2019), while in April the total numer of emergency surgical procedures was similar. Only appendectomy, complicated hernia repair and colonic resection were significantly reduced (40%, 48% and 33% respectively). The number of small intestine excision, cholecystectomy and lysis of peritoneal adhesions remained stable throughout the entire period. No statistically significant differences were found considering age, sex, Emergency Surgery Score, mortality, ICU postoperative admission and time between admission and surgery, even when analyzed with multivariate analysis for every single surgical procedure, suggesting a comparable disease severity and comorbility patterns. Mortality in COVID patients was 25%, compared to 7% of no-covid patients.
The COVID pandemic has caused major changes in daily clinical practice, especially in areas such as Emergency. This has led to a temporary reduction and changes in the flow of patients to the emergency room, with implications also for emergency surgical activities.

A total of 48 Sprague-Dawley rats were randomly divided into sham-operated group (n=12), model group (n=12), low-dose group (n=12) and high-dose group (n=12). Next, rat models of sepsis-induced liver injury were established through cecal ligation and puncture (CLP). At 12 h after surgery, blood was collected by heart puncture to detect liver function of the rats. It was found that the activity of alanine aminotransferase (ALT) and aspartame aminotransferase (AST) and the content of total bilirubin were reduced in low-dose group and high-dose group. Hematoxylin-eosin (HE) staining results revealed that after treatment with IL-22, the liver injury was relieved compared with model group. Moreover, the results of TUNEL staining assay revealed that the apoptosis level of liver cells declined after treatment with IL-22. Enzyme-linked immunosorbent assay (ELISA) results demonstrated that the levels of IL-6 and TNF-α were reduced, while the level of IL-10 was increased after treatment with IL-22. Moreover, it was discovered that the SOD content was overtly elevated in low-dose and high-dose groups compared with that in the model group. Finally, using Western blotting, it was confirmed that in comparison with the model group, the levels of Bcl-2/Bax and JAK/STAT3 signaling pathway-related proteins were markedly raised, while the level of Caspase-3 was decreased in the low-dose and high-dose groups. In conclusion, IL-22 can improve liver function, reduce the apoptosis level of liver cells, the expression of apoptosis-related proteins and the release of inflammatory factors, and alleviate liver injury by activating the JAK/STAT3 signaling pathway.
The aim of this research study is to develop a queue assessment model to evaluate the inflow of walk-in outpatients in a busy public hospital of an emerging economy, in the absence of appointment systems, and construct a dynamic framework dedicated towards the practical implementation of the proposed model, for continuous monitoring of the queue system.
The current study utilizes data envelopment analysis (DEA) to develop a combined queuing-DEA model as applied to evaluate the wait times of patients, within different stages of the outpatients' department at the Combined Military Hospital (CMH) in Lahore, Pakistan, over a period of seven weeks (23rd April to 28th May 2014). The number of doctors/personnel and consultation time were considered as outputs, where consultation time was the non-discretionary output. The two inputs were wait time and length of queue. Additionally, VBA programming in Excel has been utilized to develop the dynamic framework for continuous queue monitoring.
The inadequate availab vital information in the form of "required" number of personnel which allows the administrators to control the queue pre-emptively minimizing wait times, with optimal yet dynamic staff allocation. Additionally, the dynamic framework specifically targets practical implementation in resource-poor public hospitals of emerging economies for continuous queue monitoring.
Spatial frequency domain imaging (SFDI) is an imaging modality that projects spatially modulated light patterns to determine optical property maps for absorption and reduced scattering of biological tissue via a pixel-by-pixel data acquisition and analysis procedure. Compressive sensing (CS) is a signal processing methodology which aims to reproduce the original signal with a reduced number of measurements, addressing the pixel-wise nature of SFDI. These methodologies have been combined for complex heterogenous data in both the image detection and data analysis stage in a compressive sensing SFDI (cs-SFDI) approach, showing reduction in both the data acquisition and overall computational time.
Application of CS in SFDI data acquisition and image reconstruction significantly improves data collection and image recovery time without loss of quantitative accuracy.
cs-SFDI has been applied to an increased heterogenic sample from the AppSFDI data set (back of the hand), highlighting the increased number of CS measurements required as compared to simple phantoms to accurately obtain optical property maps. A novel application of CS to the parameter recovery stage of image analysis has also been developed and validated.
Dimensionality reduction has been demonstrated using the increased heterogenic sample at both the acquisition and analysis stages. A data reduction of 30% for the cs-SFDI and up to 80% for the parameter recover was achieved as compared to traditional SFDI, while maintaining an error of <10 % for the recovered optical property maps.
The application of data reduction through CS demonstrates additional capabilities for multi- and hyperspectral SFDI, providing advanced optical and physiological property maps.

Optical coherence tomography (OCT) is widely used as a potential diagnostic tool for a variety of diseases including various types of cancer. link2 However, sensitivity and specificity analyses of OCT in different cancers yield results varying from 11% to 100%. Hence, there is a need for more detailed statistical analysis of blinded reader studies.
Extensive statistical analysis is performed on results from a blinded study involving OCT of breast tumor margins to assess the impact of reader variability on sensitivity and specificity.
Five readers with varying levels of experience reading OCT images assessed 50 OCT images of breast tumor margins collected using an intraoperative OCT system. Statistical modeling and analysis was performed using the R language to analyze reader experience and variability.
Statistical analysis showed that the readers' prior experience with OCT images was directly related to the probability of the readers' assessment agreeing with histology. Additionally, results from readers with prior experience specific to OCT in breast cancer had a higher probability of agreement with histology compared to readers with experience with OCT in other (noncancer) diseases.
The results from this study demonstrate the potential impact of reader training and experience in the assessment of sensitivity and specificity. link3 They also demonstrate even greater potential improvement in diagnostic performance by combining results from multiple readers. These preliminary findings suggest valuable directions for further study.
