Surgery remains the treatment of choice of HCC and is indicated whenever possible. We present the case of a patient 66 years old , at which abdominal CT scan reveals the presence of HCC in segments 4 and 8, broken, and perisplenic and perihepatic fluid accumulation in the context of declining hemoglobin. Associate there is an incomplete picture of the portal convergence of 1.9 cm, with the lack of visualization of the left portal wreath. Even in the absence of the possibility of curative resection due to spontaneous rupture of the liver tumor, it is made a central necessity hepatectomy and subsegmentectomy 2 and 3 for the other three formations located at this level. Patient's postoperative course was favorable and he was discharged 11 days after surgery. Abdominal MRI performed 2 months postoperatively revealed the...

In some cases, it can take a malignant turn and grow as a pelvic mass known as malignant peripheral nerve sheath tumor (MPNST), malignant schwannoma, malignant neurofibroma, malignant mesenchynoma and neurogenic sarcoma. Our case report presents a female patient presenting dysuria and pelvic pain. The clinical examination revealed a palpable mass in the lower abdomen. The computer tomography (CT) scan of the abdomen and pelvic region showed a tumor mass that was in contact with the nearby organs, but not infiltrating them. After the surgery, histopathology confirmed the MPNST proliferation. A month after, the patient returned for a follow-up and presenting pelvic pain. The CT scan of the abdomen and pelvic region showed a tumoral mass compressing the nearby organs, but not infiltrating the...

These interactions can be captured through probabilistic models of conditional independence between heterogeneous variables. Our research included 18 subjects (aged 4 to 28 years) genetically diagnosed with Prader–Willi syndrome and a healthy control group (matched age and sex). A morphometric and cephalometric analysis was performed upon all the subjects in order to obtain the needed specific data. We have, therefore, firstly deployed several integrated Gaussian graphical models (GGMs) to capture the positive and negative partial correlations and the intensity of the connections between numerous credentials configured to determine specific cranio-facial characteristics of patients with PWS compared to others without this genetic disorder (cas...

The research endeavor is configured on a two-fold approach, including a detailed observation of the evolution of 274 hospitalized patients with COVID-19 (145 in the first wave and 129 in the second wave of infection) according to specific treatment methods applied and patients’ individual features, as well as an econometric (quantitative) analysis through structural equation modeling and Gaussian graphical models designed to acknowledge the correlations and causal relationship between all considered coordinates. The main results highlight that the specific treatment methods applied had a positive influence on the evolution of COVID-19 patients, particularly ...

The methodological endeavor was based on two advanced econometric techniques, namely, structural equation modelling and network analysis through Gaussian graphical models, applied for each group of EU countries, analyzed during the period of 1995–2017. The main results revealed significant differentiation among the new and old EU countries as follows: public health support was found to have a positive impact on healthy aging and well-being of older people, on other social determinants, and on people’s perceived good and very good health; overall, significant influences were revealed in terms of the aging dimensions. The ...
