Total Artificial Heart Implantation as a Bridge to Transplantation in Slovakia.

Although left ventricular assist device implantation represents the majority of durable mechanical circulatory support implants for patients with advanced heart failure, as many as 20 to 30% will subsequently have right heart failure requiring extended inotropic support or short-term mechanical circulatory support, and the total artificial heart is an established tool in the bridge to transplant armamentarium. The aim of this short report is to present our center's experience with the use of SynCardia total artificial heart. Between November 2017 and April 2021, 10 SynCardia total artificial heart devices were implanted.

Pre-Operative Mechanical Bowel Preparation Does Not Affect the Impact of Anastomosis Leakage in Left-Side Colorectal Surgery-A Single Center Observational Study.

Despite rapid advances in colorectal surgery, morbidity and mortality rates in elective gastrointestinal surgery play a significant role. For decades, there have been tempestuous discussions on preventative measures to minimize the risk of anastomotic dehiscence. When mechanical bowel preparation before an elective procedure, one of the key hypotheses, was introduced into practice, it was assumed that it would decrease the number of infectious complications and anastomotic dehiscence.

The importance of sentinel lymph node intraoperative frozen analysis for indication of lateral neck dissection in patients with medullary thyroid cancer.

Our research seeks to evaluate the utility of intraoperative frozen analysis of sentinel lymph nodes (SLNs) in the lateral cervical compartment (LCC) as a tool to inform decision-making regarding therapeutic neck dissection in patients with medullary thyroid carcinoma (MTC). This is particularly relevant due to the variability observed in guidelines regarding the indication for lateral neck dissection in this patient population. The study comprised 64 patients (25 males, 39 females) aged between 29 and 81 years, with a median age of 59, who underwent surgery for MTC at stage T1-3N0-1M0 between January 1, 2012, and December 31, 2020.

Thromboembolic complications following implantation of durable left-ventricular assist devices.

Introduction: As the utilization of left-ventricular assist devices (LVADs) continues to rise and patients experience extended survival duration with these devices, the overall incidence of adverse events and complications has shown a notable increase. Among the major adverse events, thromboembolic complications are particularly significant. The aim of this study is to present our experience and assess the risk of thromboembolic complications after implantation of durable continuous-flow left-ventricular assist devices (CF-LVAD) in patients with end-stage heart failure.

Temporal Analysis in Outcomes of Long-Term Mechanical Circulatory Support: Retrospective Study.

Background:  Mechanical assist device indications have changed in recent years. Reduced incidence of complications, better survival, and the third generation of mechanical support devices contributed to this change. In this single-center study, we focused on two time periods that are characterized by the use of different types of mechanical support devices, different patient characteristics, and change in the indications.

The importance of sentinel lymph node diagnostic biopsy from the lateral neck compartment in the surgical treatment of papillary thyroid cance.

Objectives: The aim of our study is to determine whether mapping the lymphatic drainage and diagnostic excision of lymph nodes from lateral neck compartment is able to detect ultrasound unknown metastases in this compartment early and thus favorably affect the prognosis of patients with papillary thyroid cancer (PTC).

Background: Lymph node involvement in the lateral neck compartment is seen in 30-60 % of patients with PTC at the time of diagnosis and affects the prognosis of patients in terms of disease recurrence.

Methods: From June 2012 to December 2016, 154 patients with no evidence of lateral nodal involvement on imaging studies were treated with total thyroidectomy and central comparment neck dissection.

The role of intraoperative frozen section of central neck lymph nodes in the management of patients preoperatively diagnosed with low- risk differentiated cancer.

Introduction: Histological examination during surgery (FS) has a place in the surgical management of differentiated thyroid carcinoma (DTC). Extending the indication for limited surgery to 4 cm tumor size (ATA guidelines 2015) cytologically verified DTCs, increases the emphasis on accurate patient selection. In our work, we reflected on the effectiveness of FS and its relationship to optimal patient management.

Radical gastrectomy with D2 lymph node dissection after neoadjuvant therapy.

Objectives: This study focuses on the evaluation of the effectiveness of radical gastrectomy with D2 node dissection after neoadjuvant therapy in the patients with gastric cancer. Gastric cancer is a widespread type of cancer, and it is the third leading cause of death in the cancer patients. Metastases most often occur in the lymph nodes and therefore, in addition to gastrectomy, lymph node dissection is often performed in the patients.

Coincidence of splenic vein aneurysm and haemorrhagic cyst of the pancreas.

Pseudoaneurysm of the splenic vein is a rare entity which is associated with pancreatitis in 52 % cases. Pseudocysts of the pancreas create approximately 70 % of all cystic lesions of the pancreas. One of the most dangerous complications of pancreatic pseudocysts is bleeding into the cystic lumen.

Preoperative nutritional support for patients undergoing elective colorectal cancer surgery - does it really work?

Aims: This study aimed to evaluate the effect of preoperative administration of oral nutritional supplements (ONS) on the self-sufficiency, physical status, and nutritional status of patients undergoing elective colorectal resections.

Methods: This prospective randomized clinical trial was conducted in a single institution. Patients scheduled to undergo colorectal cancer surgery were randomized to either ONS twice per day for 7 days before surgery or no ONS.

Predictive model using hemoglobin, albumin, fibrinogen, and neutrophil-to-lymphocyte ratio to distinguish patients with colorectal cancer from those with benign adenoma.

Colorectal cancer (CRC) is associated with inflammation, activation of coagulation, and mild anemia. Hematological parameters reflecting ongoing cancer may have the potency to be effective for early diagnostics of CRC. The aim of this study was to examine the validity and relationship between some biochemical and hematological parameters for the early diagnosis of CRC.

The role of subtotal and total gastrectomy in the treatment of gastric cancer.

The optimal procedure for the lower third gastric adenocarcinoma is still an open question. We performed an analysis of the long-term survival of patients after subtotal (SG) or total gastrectomy (TG) on 164 enrolled patients. Bivariate and multivariable analyses were performed in order to identify characteristics associated with long-term survival.

Diagnostic ipsilateral central neck dissection may reduce undertreatment of initially low-risk papillary thyroid cancer.

Although small papillary thyroid cancer (PTC) patients are considered as low-risk population, approximately 5-20% of these patients relapse after surgery. The objective of this single-center retrospective study was to identify risk factors, which could help to distinguish patients who would need additional treatment after surgery. A total of 268 patients (39 men, 229 women, median age 49 years) underwent surgery between 2007-2015, and fulfilled inclusion criteria: tumor size ≤20 mm, absence of metastatic lymph nodes (LN) in the lateral neck compartment (LC), and absence of local invasion.

Collision of a neuroendocrine tumor and ductal adenocarcinoma of the pancreas: a rare case report.

Despite the increased incidence of pancreatic cancer, reported data of collision pancreatic tumors are very rare, limited just to sporadic cases. There are only two described cases of the collision pancreatic tumor consisting of neuroendocrine and pancreatic ductal adenocarcinoma in the literature. Currently, we are presenting a case of a young female patient with pancreatic ductal adenocarcinoma surrounding a smaller focal lesion of the well-differentiated neuroendocrine pancreatic tumor.

Acute appendicitis: Clinical anatomy of the new palpation sign.

Introduction: Currently, diagnosis of acute appendicitis (AA) is challenging. Here, we aim to propose using the new palpation sign to diagnose AA and establish the effectiveness of clinical examination using a proprietary diagnostic palpation procedure.

Materials And Methods: We retrospectively analyzed 2,883 patients of all ages who were examined for suspected AA, of whom 532 patients required surgical intervention, using the new palpation sign.

Postoperative pancreatic fistula after pancreatic resection.

Background: The failure of pancreatic anastomosis after the proximal pancreaticoduodenectomy (PD) and the failure of pancreatic stump after the distal pancreatectomy with a resulting postoperative pancreatic fistula remain the most feared complications after pancreatic resection. Surgeons have been trying to find a reliable reconstructive technique of pancreatic anastomosis for decades.

Methods: A literature search was performed to January 2020.

Ampullary cancer in a patient with familial adenomatous polyposis - a rare case report and current status of management.

Familial adenomatous polyposis (FAP) is an inherited autosomal dominant disorder. Extracolonic manifestations are seen quite often. As prophylactic colectomy has become a standard care in FAP patients, the concerns over the development of associated extracolonic malignancies have become more prevalent.

Recurrence after sentinel lymph node biopsy in cutaneous melanoma: a single-center experience in Slovak patients.

The standard approach in the management of cutaneous malignant melanoma is considered to be a complete excision of the primary lesion with an appropriate margin of the normal tissue according to Breslow thickness. Usually sentinel lymph node biopsy (SLNB) can help to determine the nodal status, and thus improve the accuracy of staging of the disease. However, the role of SLNB in melanoma treatment remains controversial.

Applications of magnetoliposomes with encapsulated doxorubicin for integrated chemotherapy and hyperthermia of rat C6 glioma.

There is substantial evidence regarding enhanced antitumor cytotoxicity of selected chemotherapeutic agents by appropriate heat exposure (40-44°C). Based upon these results, the integration of hyperthermia as an additional treatment modality given simultaneously with systemic chemotherapy is currently of considerable interest. Hyperthermia can be induced by alternating magnetic field and magnetic nanoparticles.

Application of cationized magnetoferritin for magnetic field-assisted delivery of short interfering RNA in vitro.

Cationized magnetoferritin is used for development of a simple, efficient, and fast delivery of short interference RNA into cells using combination of magnetophoresis for pre-concentration of siRNA-magnetoferritin complex on the surface of plated cells with subsequent application of nanosecond laser pulses producing stress waves in transfection chamber, which permeabilize cell membrane for the facilitated delivery of siRNA into the cell interior. As has been quantified using siRNA inducing cell death assay, by combination of these two physical factors we have obtained high efficiency for tested three different human carcinoma cells. Proposed method of gene silencing based on cationized magnetoferritin is a versatile and easily accessible platform with many possible applications in gene therapy.
