RESUMO
INTRODUCTION AND AIM: Identifying the best practices to obtain consent for organ donation involves several strategies. This retrospective analysis of the activity in the field of organ donation identifies the most critical impediments, of which the refusal of families to donate is one of the most frequently encountered. Our main aim was to determine the factors that negatively influence the activity of organ and tissue donations from brain dead donors and to summarize the total number of potential and actual deceased donors, their yearly characteristics, and the organ and tissue donation types performed. MATERIALS AND METHODS: A retrospective descriptive study, covering data from 1 January 2014 to 31 December 2023, was conducted in the intensive care unit of the Emergency Clinical County Hospital of Bihor, a recognized facility engaged in organ donation and transplantation from Romania. All potential and actual deceased donors were included in our research. RESULTS: During a period of 10 years, between 2014 and 2023, of the 488 potential and actual deceased donors, 355 (72.7%) were potential donors and 133 (27.3%) actual deceased donors. CONCLUSIONS: From 2014 to 2023, a significant percentage [15.28% (133)] of the total number of actual deceased organ donors registered at the national level (870) were identified by us in the Emergency Clinical County Hospital of Bihor.
RESUMO
Background: The need to maximize the use of donor organs and the issue of ischemia-reperfusion injury led to the use of thermoregulated oxygenated machine perfusion that improves the function of liver graft prior to transplantation. Among these methods, the HOPE (hypothermic oxygenated perfusion) protocol shows significant benefits. The aim of the paper is to analyze the early experience in using such procedure in a high-volume liver transplantation center. Methods: Normal liver grafts with cold ischemia time â?¥6 hours, marginal grafts and discarded (beyond ECD criteria) grafts were perfused using HOPE. Our selection criteria for dual HOPE (hepatic artery and portal perfusion) were steatosis, at least 3 associated ECD criteria, and discarded grafts. The main criteria to establish graft improvement were the progressive increase of arterial and portal flows, with lactate under 3 mmol/L or, even if over this value, with a decreasing trend during perfusion. Results: Whole liver grafts harvested from 28 donors between February 2016 and June 2021 benefitted from HOPE: 9 otherwise discarded grafts were assessed and considered not fit for transplantation, while the other 19 were ECD or standard grafts that were subsequently transplanted. Dual HOPE was used in 8 out of the 19 procedures (42.1%). We obtained a significant increase of arterial and portal flow (p=0.005 and p=0.001, respectively). In recipients, significant improvement of AST, ALT, INR and lactate values were recorded (p 0.001, p 0.001, p 0.001, and p=0.05, respectively). The rate of major postoperative complications (Dindo-Clavien grade 3) after LT was 26.3%, while the rate of early graft dysfunction was 15.8%. No PRS or acute rejection was recorded. The postoperative mortality rate was 15.8%. After a median follow-up of 9.3 months (range 2-44), the late major complication rate was 15.8%, without mortality. Conclusion: Machine perfusion is nowadays part of current clinical practice. This way, marginal liver grafts (DCD, ECD-DBD) may be safely used for transplantation improving the outcome, thus effectively enhance the use of a persistent scarce pool of donors. For best results, we believe that both techniques of HOPE (mono and dual HOPE) should be used based on specific selection criteria.

Osteoarthritis is mainly located in the knee area. It is an important concern related to the population health, determined by the influence on the quality of life of patients. Total knee arthroplasty (TKA) with uncemented fixation is among the most encountered procedures performed in patients of a younger age. The present study investigated the response of patients (quality of life, mobility and pain management) with titanium/hydroxyapatite-coated implants with polyethylene inserts. A total of 57 patients with knee arthroplasty were studied with an average age of 54.1±4.9 years and 57.8% were females. The present study focused on the following aspects: The components of such a prosthesis and the way they contribute to a physiological fixation/recovery; how the implant surgery is performed; the clinical and demographic characteristics of the patients; postoperative pain assessment in different types of movement; the management of the movement capacity 1 year after the surgery; and complications that may occur. One year after the surgery, these patients reported pain release, considerably favorable results in every-day activities, and good mobility (capable of using the car, rising from the bed or standing). Knowledge and accurate observation of the correct steps in performing this surgery and the role of the components of the prosthesis can lead to favorable therapeutic outcomes for patients with knee osteoarthritis.
RESUMO
A well-functioning immune system of the host body plays pivotal role in the maintenance of ordinary physiological and immunological functions as well as internal environment. Balanced immunity enhances defense mechanism against infection, diseases and unwanted pathogens to avoid hypersensitivity reactions and immune related diseases. The ideal immune responses are the results of corrective interaction between the innate immune cells and acquired components of the immune system. Recently, the interest towards the immune system increased as significant target of toxicity due to exposure of chemicals, drugs and environmental pollutants. Numerous factors are involved in altering the immune responses of the host such as sex, age, stress, malnutrition, alcohol, genetic variability, life styles, environmental-pollutants and chemotherapy exposure. Immunomodulation is any modification of immune responses, often involved induction, amplification, attenuation or inhibition of immune responses. Several synthetic or traditional medicines are available in the market which promptly have many serious adverse effects and create pathogenic resistance. Phytochemicals are naturally occurring molecules, which significantly play an imperative role in modulating favorable immune responses. The present review emphasizes on the risk factors associated with alterations in immune responses, and immunomodulatory activity of phytochemicals specifically, glycosides, alkaloids, phenolic acids, flavonoids, saponins, tannins and sterols and sterolins.

Background and objectives: Diabetic foot ulcer (DFU) is one of the serious complications of diabetes, being related to frequent and long-term hospitalisation, reduced quality of life of the patient, amputations, a high rate of morbidity and mortality. The bacterial aetiology is complex, sometimes involving more than one pathogen, playing a major role in the infection prognosis and development of microbial resistance. This study evaluated the current state of the aetiology, clinical and pathological characteristics of DFU in a single diabetes centre in order to provide some specific measures to prevent it. Materials and Methods: This retrospective study was conducted on patients with diabetes mellitus (252 individuals diagnosed with DFU) between January 2018-December 2019. All participants were assessed based on their clinical characteristics, including complications of diabetes and pathological and microbiological evaluations. Results: The present research revealed that diabetic foot ulcer prevalence was higher in males than in females and higher in type 2 diabetic patients than in type 1 diabetic patients. The patients with diabetic foot ulcer were older, had a higher body mass index (BMI), longer diabetic duration and had more diabetic complications, such as retinopathy, diabetic polyneuropathy and diabetic kidney disease, than patients without diabetic foot ulceration. Conclusions: Taking into account all factors involved, including the aetiology and the antibiotic susceptibility pattern of these isolates, planning the suitable treatment options of patients is possible.

Patients with type 2 diabetes exhibit higher cardiovascular risk than normal individuals. Optimal blood glucose levels are rarely achieved in diabetic patients. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as a new antidiabetic drug class with multiple metabolic effects. Some trials have evaluated their safety, but it has been recently demonstrated that this new class has cardiovascular benefits, through other mechanisms than glycemic control. The use of GLP-1RAs was associated with a significant reduction of cardiovascular and all-cause mortality, with a safe profile related to pancreatitis or thyroid cancer, as compared with placebo. This review presents the cardiovascular and metabolic benefits of GLP-1 RAs versus placebo, in patients with type 2 diabetes. Semaglutide and liraglutide demonstrated a reduction in cardiovascular events, with similar rates on cardiovascular mortality. Ongoing trials assess the cardiovascular benefits and side effects of dulaglutide treatment. Exenatide and liraglutide demonstrated the decrease of blood pressure values, weight reduction and improvement of dyslipidemia. Liraglutide induced, both in vivo and in vitro, an improvement of blood circulation, increasing the nitric oxide level and inhibiting the adhesion and procoagulant factors. Also, liraglutide demonstrated beneficial effects on cardiac remodeling after myocardial infarction, but more large trials are required. However, the international guidelines recommend using GLP-1 RAs as first-line therapy in type 2 diabetes patients with high cardiovascular risk or as first-line agents in patients intolerant to metformin.
RESUMO
Metabolic syndrome is associated with increased risk of cardiovascular disease. This study investigated the correlation between adipocyte and inflammation biomarkers, and metabolic syndrome and its components. The study included 80 patients with normal body-mass index and 80 obese patients. The groups were assessed for serum values of adiponectin, leptin and highly sensitive C reactive protein (hsCRP), the homeostatic model assessment of insulin resistance (HOMA-IR), as well as the influence of these biochemical markers on the prevalence of metabolic syndrome and its components. Leptin, HOMA-IR and hsCRP had statistically significant (P<0.01) higher values in the group of obese subjects, while adiponectin had statistically significant (P<0.01) lower values. The prevalence of metabolic syndrome was 35% in the obese group and 5% in the normal weight group. Adiponectin and HOMA-IR were the variables significantly associated with metabolic syndrome (P<0.01), adiponectin/HOMA-IR ratio and leptin/adiponectin ratio were also associated with metabolic syndrome (P<0.01). No relationship was found between metabolic syndrome and hsCRP. Adiponectin and adiponectin/HOMA-IR were associated with all the components of metabolic syndrome and they can be useful to identify patients with high risk of diabetes mellitus and cardiovascular disease.
RESUMO
Obesity and overweight are major contributors to the morbidity and mortality of modern civilization. This study determined the prevalence of certain risk factors for adiposity and assesses their impact on overweight/obesity prevalence. Nine hundred individuals were evaluated, aged between 18-65 years, including clinical examination, evaluation of medical history, BMI determination and completion on questionnaires assessing nutritional intake and presence of depression symptoms. Overweight prevalence was 29.56% and obesity prevalence was 21.33%. Fast-food consumption was the most frequent risk factor for adiposity found in 61.67% of individuals, eating <3 meals/day was found in 58.89%, sedentary lifestyle in 53.33%, sleeping time <6 h/day in 44.22%, hypercaloric nutrition in 43.56%, excessive alcohol consumption in 42.89% and depression symptoms in 31.78%. Unhealthy lifestyle a composite risk factor was identified in 67.33% of individuals. Fast-food consumption increases the risk for adiposity by 1.85-fold while sedentary lifestyle by 1.79-fold. Risk factors for adiposity play an important role in increasing the prevalence of overweight and obesity. Public health measures are necessary in order to educate the general population regarding the importance of healthy nutrition and physical exercise.
RESUMO
Stroke represents a serious illness and is extremely relevant from the public health point of view, implying important social and economic burdens. Introducing new procedures or therapies that reduce the costs both in the acute phase of the disease and in the long term becomes a priority for health systems worldwide. The present study quantifies and compares the direct costs for ischemic stroke in patients with thrombolysis treatment versus conservative treatment over a 24-month period from the initial diagnosis, in one of the 7 national pilot centres for the implementation of thrombolytic treatment. The significant reduction (p < 0.001) of the hospitalization period, especially of the days in the intensive care unit (ICU) for stroke, resulted in a significant reduction (p < 0.001) of the total average costs in the patients with thrombolysis, both at the first hospitalization and for the subsequent hospitalizations, during the period followed in the study. It was also found that the percentage of patients who were re-hospitalized within the first 24-months after stroke was significantly lower (p < 0.001) among thrombolyzed patients. The present study demonstrates that the quick intervention in cases of stroke is an efficient policy regarding costs, of Romanian Public Health System, Romania being the country with the highest rates of new strokes and deaths due to stroke in Europe.

The spectrum and antibiotic sensitivity of isolated strains vary between departments, hospitals, countries; the discrepancies are related to the use and dosage of these antibiotics. The purpose of our research was to compare the type of pathogens and the susceptibility of the isolated strains, as well as the use of antibiotics in the surgical departments of the Emergency Clinical County Hospital, Oradea, Romania; for one year, all the patients admitted to the mentioned sections were monitored. Antibiotic sensitivity of isolated strains was expressed using cumulative antibiogram. The total consumption of antibiotics was 479.18 DDD/1000 patient-days in the surgical sections. The most commonly used drugs were cephalosporins third and first generation, and clindamycin. Infections of wounds, urinary tract and fluids were most commonly diagnosed, and the most isolated was Escherichia coli, followed by Staphylococcus aureus and Enterococcus faecalis. The most commonly prescribed antimicrobial was ceftriaxone, but its sensitivity was low. This study revealed that the intake of antimicrobials in the surgical sections is increased and the comparison of antimicrobial prescriptions, sensitivity rates, and the spectrum of isolated pathogens showed differences between antimicrobials.
RESUMO
When we discuss the genetics of tumors, we cannot fail to remember that in the second decade of the twentieth century, more precisely in 1914, Theodore Boveri defined for the first time the chromosomal bases of cancer. In the last 30 years, progresses in genetics have only confirmed Boveri's remarkable predictions made more than 80 years ago. Before the cloning of the retinoblastoma 1 (RB1) gene, the existence of a genetic component in most, if not all, solid childhood tumors were well known. The existence of familial tumor aggregations has been found much more frequently than researchers expected to find at random. Sometimes, the demonstration of this family predisposition was very difficult, because the survival of children diagnosed as having a certain tumor, up to an age at which reproduction and procreation is possible, was very rare. In recent years, advances in the diagnosis and treatment of these diseases have made it possible for these children to survive until the age when they were able to start their own families, including the ability to procreate. Four distinct groups of so-called cancer genes have been identified: oncogenes, which promote tumor cell proliferation; tumor suppressor genes, which inhibit this growth/proliferation; anti-mutational genes, with a role in deoxyribonucleic acid (DNA) stability; and micro-ribonucleic acid (miRNA) genes, with a role in the posttranscriptional process.

Malignant melanoma is one of the common skin cancers but as a primary cancer localized in urinary bladder is a very rare clinical entity, 0.2% of all melanomas. We report the very rare case of primary malignant melanoma of the bladder in an 80-year-old man. According with our knowledge is the first case of primary malignant melanoma reported in Romania. Only a few percent of malignant melanoma have origin outside the skin. Less than 30 cases of primary bladder melanoma have been reported in the literature. The most common metastasis in urinary bladder comes from breast carcinoma and skin melanoma The tissue examination presents the same futures does not matter if is a primary or secondary malignant melanoma. The ancillary tests like immunohistochemistry help us to do an accurate diagnostic but to discriminate primary vs. metastatic tumor remain an important issue. Usually, the bladder melanoma has an aggressive lethal behavior. Histopathological examination, immunohistochemistry, clinical history, and endoscopic evaluation can provide certain diagnostic features.

Antibiotic sensitivity spectrum of isolated strains differs according to hospital departments, the hospitals themselves, and countries. Discrepancies also exist in terms of antibiotic use and dosage. The aim of the present study is to compare the antibacterial agents, the types of infections, the number and type of pathogens, and the sensitivity to antibiotics used in the Intensive Care Unit (ICU) of the Emergency Clinical County Hospital of Oradea, Romania. Over a one-year period, data were gathered from the pharmacy computer system and medical records of inpatients. WHO Anatomical Therapeutic Chemical (ATC)/defined daily doses (DDD) methodology was used to assess drug administration data, and antibiotic use was expressed as DDD/1000 PD (patient days). The antibiotic susceptibility of isolated strains was expressed through the cumulative antibiogram. The overall consumption of antimicrobial agents was 1247.47 DDD/1000 PD. The most common drugs used were cephalosporins and fluoroquinolones (52.97% of the total). Ceftriaxone was the most commonly used, followed by levofloxacin. Infections of the respiratory and urinary tract were the most frequently diagnosed infections. The most commonly isolated bacteria type was Acinetobacter baumannii (22.12% overall), isolated especially from the respiratory tract and resistant to all the ß-lactam antibiotics including carbapenems. Antimicrobials intake at the ICU is much higher compared to medical and surgical wards. After we tested the existence of a possible connection between antibiotic consumption and antibiotic resistance of bacteria, it was revealed that on our sample exists a poor positive association.

Introduction: In gastric cancer there are multiple local and general risk factors for the occurrence of postoperative fistulas. In the present study, we proposed to analyse the role of the preoperative nutritional state and nutritional therapy along with the disease stage, the age and the sex of patients in the occurrence of fistulas. Material and method: This retrospective study included 158 patients operated for gastric cancer in Surgery Department of Bucharest Oncology institute between January 2010 and December 2016 in which we analysed the incidence of anastomotic fistula according to the nutritional status, disease status, age and sex of the patients. Results: The global incidence of fistulas was of 11%, out of which 8 % were fistulas of the duodenal stump and 3.19% fistulas of the eso-jejunal anastomosis. Out of the 30 patients with weight loss and parenteral nutrition in the preop period, we had 4 fistulas (13%), and out of the 36 patients with weight loss and nutritional measures in the postop we had 5 fistulas (14%), also, out of the 24 patients with weight loss and without nutritional intervention, we had 5 fistulas (21%), finally, out of the 68 patients without weight loss we had fistulas in 4 patients (6%).. The incidence of fistulas was 5% in patients with stage I, II and III and 24% in stage IV patients. The distribution of fistulas according to the age of the patients showed a much higher incidence of fistulae in patients over 70 years old. Conclusions: The number of postoperative fistulas was higher in the advanced stages of the disease (p=0.027) and in patients over 70 years old (p=0.047) and the differences were statistically significant. The difference between the number of fistulae occurred in patients who had weight loss but did not receive nutritional support from those who received this support was not statistically significant (p 0.001).

Liver fibrosis is one of the most serious histopathological (HP) lesions that, together with the inflammatory process and the hepatocyte lesions, determine the change of the liver architecture, having as a clinical result the onset of liver failure phenomena. Hepatitis C virus represents one of the most frequent conditions leading to the onset of liver fibrosis and favors the progression of the disease towards hepatocellular carcinoma. We evaluated the HP and immunohistochemical (IHC) aspects on fragments of liver biopsies taken from 104 patients diagnosed with chronic hepatitis C and altered capacity of work. In our study, we observed a growth of the portal (Kiernan) spaces by the presence of a chronic inflammatory infiltrate, the presence of collagen fibers and conjunctive matrix. The density and dimensions of collagen fibers were correlated with the severity of the liver disease, in the severe forms being highlighted porto-portal and porto-central fibrous bridges. The IHC examinations highlighted the change of the phenotype of perisinusoidal dendritic cells, the growth of the myofibroblast cells in the portal spaces, the growth of the macrophage number in the inflammatory infiltrate and of the Kupffer cells in the liver parenchyma.
