Lean Construction has proven to be highly beneficial to the construction industry; however, adoption at the trade contractor level is lagging. This study seeks to identify the barriers that hamper the successful implementation of lean principles and methods to understand the reasons for the lagging adoption by stakeholders that should benefit the most. A comprehensive review of previous literature identified several categorizations for barriers; however, none emphasized trade contractors. 29 barriers were identified and defined through a detailed literature review. These barriers were then clustered into seven main factors affecting the implementation of lean initiatives under the proposed framework. This framework facilitates the investigation of construction companies' potential barriers when deciding to start implementing lean. The analysis revealed that the three most frequent barriers were lack of teamwork, multi-layer subcontracting, and lack of long-term philosophy. Additionally, seven barriers are recognized as the potential barriers specifically relevant to the trade contractors: lack of teamwork and technical capabilities, poor communication between parties, minimum involvement of workers, lack of integration of the production chain, quality of materials, high turnover of the workforce, and employee tolerance of untidy workspaces. The findings provide insight into the possible obstacles that exist to hinder the implementation of lean practices among trade contractors. Firms that do not recognize these barriers will suffer from organizational inefficiency regarding needed improvement efforts and where these endeavors should be focused. Understanding the root causes of the low rate of lean adaptation can assist in developing solutions to address barriers and facilitate lean implementation.

Worldwide breast cancer (BC) represents one of the most common type of cancer. Mortality from this disease is declining due to new therapies, but many patients face the side effects of cancer and treatment. The most common side effect is the lymphedema of the upper extremity. Although the incidence of lymphedema secondary to breast cancer is 63.4%, there are few studies on the immune mechanisms responsible for lymphedema and healing. Extensive research of the development, structure and function of the lymphatic system must be performed to identify the role of lymphatic vessels in breast cancer. All this can lead to discovery of new potential biomarkers in lymph in order to improve early detection and treatment of lymphedema and the current strategies for controlling tumor metastasis.

Arterial stiffness provides an indirect picture of vascular calcifications in terms of the effect they have on the systemic circulation and consequently on the heart. The present study sought to demonstrate the usefulness of outpatient investigation of vascular calcifications in dialysis patients using pulse wave velocity (PWV) determination. The aim of the study was to determine arterial resistance in patients with chronic dialysis kidney disease. The average study period was 48.5 ± 19.0 (SD) months. The study included 203 patients on dialysis with BCRT. The determination of arterial stiffness was measured at an interval of one hour after the dialysis session. The study highlighted the presence of an increased cardiovascular risk related to the presence of vascular calcifications without being able to establish a direct linear and causal link between their presence, location and the risk of cardiovascular events. The importance of highlighting calcifications and the consequences they generate means the possibility of influencing the main elements that can generate acute cardiovascular events. The results obtained and the correlations performed give an overview of the pathology studied, providing premises for therapeutic influence and risk assessment.

Introduction. The idea for our clinical research came from the association between type 2 diabetes and autoimmune thyroiditis that we often see in our daily practice. We wanted to study this to see if it is only a coincidence or if indeed this association really exists. Method. We created an observational retrospective research using 5,064 patients with type 2 diabetes, patients from Sanamed Hospital, which came at site between January 2016 and December 2018. Out of the large group of patients, we created 3 secondary groups: one containing 50 patients with type 2 diabetes, one with 50 patients with autoimmune thyroiditis and one with 50 patients which had both diseases. We initially evalueted the large group and after that we studied the 3 smaller groups. Results. We were able to prove the main hypothesis of our study by showing that the incidence of thyroiditis was significantly higher in the population with type 2 diabetes from our main group, the 5,064 patients, in contrast with the incidence that thyroiditis has in the healthy population from Europe. In our study we also demonstrated that the association between this 2 diseases has a protective role in regards with the incidence of obesity, arterial hypertension, dyslipidemia and macrovascular complications of the type 2 diabetes. Also, we found out that in the case of this association there are significant differences for a serial of biochemical parameters as well, such as blood glucose, uric acid, elements of the lipid profile. Discussions. The results from our study were consistent with the results form other international studies regarding this topic. This finding led us to the conclusion that our initial observation, that this two conditions might be associated, was not only a coincidence, but it is a definite association proved by us in this study. Conclusions. We proved our initial hypothesis to be true by the significant difference in incidence of thyroiditis in the population of our study in comparison with the incidence of thyroiditis in the healthy European population. We also managed to prove the secondary hypothesis to be correct.

The diagnosis of vascular tumors and malformations is usually achieved with clinical history and physical examination. The imaging of these patients has been sufficiently refined to answer pertinent questions when trying to make an accurate differential diagnosis in order to establish an informed treatment plan. The imaging modalities at hand include ultrasound, doppler sonography, magnetic resonance imaging and contrast material enhanced magnetic resonance angiography. We present two cases of different vascular anomalies that were managed according to the clinical aspect, natural history and imaging performed. Moreover, with better understanding of the imaging features, the radiologist has become a key player in the diagnosis and management plan of the vascular anomalies. This is crucial in avoiding misdiagnosis and improper treatment.

Colorectal cancer spreads via multiple pathways, the most commonly encountered ways being represented by the peritoneal and hematogenous ones as well as by direct contiguity. At this time significant benefits in terms of survival have been reported in cases presenting locally advanced lesions and for those presenting extended peritoneal lesions of peritoneal carcinomatosis especially if radical resection is achievable. In this respect, certain authors went further and investigated whether the association of the two surgical strategies – extended pelvic resections and cytoreductive surgery of the peritoneal metastases could improve survival in cases in which both patterns of spread are present. Meanwhile, the possibility of association of hyperthermic intraperitoneal chemotherapy (HIPEC) was also investigated. The aim of the current study is to review and analyze the most relevant studies conducted on this issue.
