Systematic Review on the Effectiveness and Outcomes of Nivolumab Treatment Schemes in Advanced and Metastatic Cervical Cancer.

Advanced and metastatic cervical cancer remains a formidable challenge in oncology, with immune checkpoint inhibitors such as the PD-1 inhibitor nivolumab emerging as a potential therapeutic option. This systematic review rigorously assesses the effectiveness and outcomes of various nivolumab treatment regimens within this patient cohort, drawing from clinical trials and real-world evidence up to December 2023. Following a comprehensive search across PubMed, Scopus, and Embase, four studies were deemed eligible, involving a collective total of 80 patients. One preliminary trial data were excluded from the final analysis, as well as four other proceedings and abstracts on the efficacy and safety of nivolumab on advanced cervical cancer. The patients' average age across these studies was 48 years, with an average of 38% having an Eastern Cooperative Oncology Group (ECOG) performance status of 1. Notably, 64% of all patients were positive for high-risk HPV, and 71% exhibited PD-L1 positivity, indicating a substantial target population for nivolumab. The analysis revealed a pooled objective response rate (ORR) of 48%, with a disease control rate (DCR) averaging 71%. Moreover, progression-free survival (PFS) at 6 months was observed at an average rate of 50%, reflecting the significant potential of nivolumab in managing advanced stages of the disease. The review highlights the influence of PD-L1 status on response rates and underscores the enhanced outcomes associated with combination therapy approaches. By delineating the variability in treatment efficacy and pinpointing key factors affecting therapeutic response and survival, this systematic review calls for further investigations to refine nivolumab's clinical application, aiming to improve patient outcomes in advanced and metastatic cervical cancer.

Design of a Synthetic Long Peptide Vaccine Targeting HPV-16 and -18 Using Immunoinformatic Methods.

Human papillomavirus types 16 and 18 cause the majority of cervical cancers worldwide. Despite the availability of three prophylactic vaccines based on virus-like particles (VLP) of the major capsid protein (L1), these vaccines are unable to clear an existing infection. Such infected persons experience an increased risk of neoplastic transformation. To overcome this problem, this study proposes an alternative synthetic long peptide (SLP)-based vaccine for persons already infected, including those with precancerous lesions. This new vaccine was designed to stimulate both CD8+ and CD4+ T cells, providing a robust and long-lasting immune response. The SLP construct includes both HLA class I- and class II-restricted epitopes, identified from IEDB or predicted using NetMHCPan and NetMHCIIPan. None of the SLPs were allergenic nor toxic, based on in silico studies. Population coverage studies provided 98.18% coverage for class I epitopes and 99.81% coverage for class II peptides in the IEDB world population's allele set. Three-dimensional structure ab initio prediction using Rosetta provided good quality models, which were assessed using PROCHECK and QMEAN4. Molecular docking with toll-like receptor 2 identified potential intrinsic TLR2 agonist activity, while molecular dynamics studies of SLPs in water suggested good stability, with favorable thermodynamic properties.

The Impact of Parental Education on Schoolchildren's Oral Health-A Multicenter Cross-Sectional Study in Romania.

The present study is part of the first national oral health survey for children in Romania. The aim of this study was to determine caries prevalence in correlation with the level of the parents' education, preventive behavior, and socioeconomic parameters in 11-14-year-old schoolchildren in Romania. A cross-sectional epidemiological survey was designed and conducted in 2019-2020. The sampled children were selected from 49 schools distributed in rural and urban areas of Romania, including its capital. Data were collected using the Oral Health Questionnaire for Children developed by the World Health Organization and described in the WHO Oral Health Surveys-Basic Methods, 5th edition, 2013, after positive informed consent. To express prevalence and severity of carious lesions, International Caries Detection and Assessment System (ICDAS) criteria were recorded in school for 814 schoolchildren (388 boys and 426 girls) aged between 11 and 14 years old (mean age 12.29 ± 0.6). Elements regarding the specificity of the child (gender, age, and parental education) were tabulated against preventive behavior. The parents' education was correlated with three clinical indices in order to assess the existence or lack of certain significant differences among schoolchildren in Romania. In terms of correlation between the mother's education and preventive behavior, results showed a significant positive correlation in case of dental check-ups (rs = 0.08 *, p < 0.05), brushing (rs = 0.02 **, p < 0.01), and use of different types of dental hygiene aids (rs = 0.06 **, p < 0.01) and a negative correlation with tooth pain or discomfort (rs = -0.01 **, p < 0.01). A statistically significant positive relationship was highlighted between the mother's education and the presence of restorations (rs = -0.09 **, p < 0.01). Regarding the father's education, there was a positive relationship with oral hygiene behavior (rs = 0.18 **, p < 0.01) but a negative relationship with the D3T index (rs = -0.18 **, p < 0.01). In conclusion, there was a strong correlation between the parents' education, preventive behavior, and oral health status of Romanian schoolchildren.

Gender Differences in Coping, Depression, and Anxiety in Patients with Non-Metastatic Lung Cancer.

Background: Depression and anxiety are prevalent issues amongst individuals suffering from thoracic cancer. Gender differences in coping with thoracic cancer have a serious impact upon the management of emotional distress. The purpose of our study has been to assess sex variations in handling anxiety and depression, including the use of coping mechanisms and their relationship with respect to anxiety and depression. Methods: This cross-sectional study registered 18 women and 22 men with non-metastatic lung cancer and operated upon. Pre-operatively and at one month post-operatively, the patients were assessed by means of scales (COPE, GAD-7 and PHQ-9). Results: Post-operatively, the intensity of depression and anxiety was substantially greater in males than in females (p = 0.049, p = 0.042). Male individuals tended to use coping mechanisms of humour (p = 0.009) and restraint (p = 0.029) significantly more frequently than women. Moreover, in women, depression correlated significantly with denial and behavioural deactivation (rho = 0.465, p = 0.029, respectively, rho = 0.562, p = 0.006); whilst anxiety, similarly, correlated with positive interpretation, behavioural deactivation, and use of social-emotional support (rho = 0.484, p = 0.022, respectively, rho = 0.590, p = 0.004 and rho = 0.502, p = 0.017). Furthermore, in males, depression correlated significantly with mental deactivation, use of social-instrumental and social-emotional support (rho = 0.702, p = 0.001, respectively, rho = 0.505, p=0.033, and rho = 0.773 with p < 0.001), whilst anxiety correlated significantly with mental deactivation, denial, and use of social-emotional support (rho = 0.597, p = 0.009, respectively, rho = 0.553 with p = 0.017 and rho = 0.755, p < 0.001). Conclusion: There were gender divergences in the use of coping mechanisms and the level of post-surgical anxiety and depression. We found significant positive relationships between some coping mechanisms and depression/anxiety. The patient's gender governs the coping style, which in turn has bearing upon the post-operative evolution.

Prevalence of Gestational Diabetes in preCOVID-19 and COVID-19 Years and Its Impact on Pregnancy: A 5-Year Retrospective Study.

Gestational diabetes mellitus (GDM) affects a total of 3% to 9% of all pregnancies. It has a high impact on both mother and baby, increases the perinatal risks, and predicts the presence of long-term chronic metabolic complications. The aim of our study is to determine the incidence of GDM in tertiary hospitals in the west part of Romania to lay out the risk factors associated with GDM and to observe the evolution of pregnancy among patients with this pathology by emphasizing the state of birth of the fetus, the birth weight, and the way of birth. We also want to compare the prevalence of GDM in preCOVID-19 (Coronavirus disease) versus COVID-19 years. The study took place between January 2017 and December 2021 at the Municipal Emergency Hospital of Timisoara, Romania. The proportion of births with GDM was significantly increased during the COVID-19 period compared to the preCOVID-19 period (chi2 Fisher exact test, p < 0.001). The period 2020−2021 represents a significant risk factor for GDM births (OR = 1.87, with 95% CI = [1.30, 2.67]). COVID years represent a risk period for developing gestational diabetes, which can be explained by reduced physical activity, anxiety, or modified dietary habits, even if the follow-up period was not impacted.

Well-Being, Depression, and Anxiety following Oncoplastic Breast Conserving Surgery versus Modified Radical Mastectomy Followed by Late Breast Reconstruction.

Breast cancer requires complex clinical care. Well-being is an intricate concept, encompassing physical, functional, emotional, and social aspects. BACKGROUND: This study aims to evaluate the relationship between the type of surgery our patients underwent and the timing of the reconstructive surgery with physical, emotional, social, and functional well-being. Furthermore, through our research we tried to identify potential mental health comorbidities in patients with breast cancer, clinical symptoms, and well-being in women with breast cancer, depending on the type of required surgery. METHODS: The study included 69 women diagnosed with breast cancer, in stages I to III, divided in two groups: I-patients with oncoplastic breast-conserving surgery and contralateral correction surgery, for symmetry reasons; II-patients who underwent modified radical mastectomy and late breast reconstruction with contralateral symmetrisation. We evaluated socio-demographic aspects, alongside depression, anxiety, stress (DASS 21), and well-being (FACT-B). Data were statistically processed; statistical significance was set at p < 0.05. RESULTS: Clinical elements of depression, anxiety, and stress were noted in both groups, without statistical significance (p > 0.05). Significant differences were found regarding psycho-emotional (p = 0.035) and functional well-being (p = 0.001), with higher scores for group I. The chi-square test indicated statistically significant differences (at p < 0.01) between the groups, regarding the frequency of scores on items B4 and B9 (FACT-B items, related to feminine aesthetics and desirability), with evidently higher scores in group I than in group II. CONCLUSIONS: The state of well-being, as well as the items related to femininity and sexuality had higher values in the group of women treated by oncoplastic conservative surgery compared to late reconstruction after modified radical mastectomy.

Retraction Note to: Implications of Entropy and Surgical Pleth Index-guided general anaesthesia on clinical outcomes in critically ill polytrauma patients. A prospective observational non-randomized single centre study.

The authors have retracted this article [1]. After publication it was discovered that Table 1 which reports the clinical and demographical characteristics of the patients in the study contains a number of statistical and typographical errors. The data reported in this article are therefore unreliable. All authors agree with this retraction.

Implications of Entropy and Surgical Pleth Index-guided general anaesthesia on clinical outcomes in critically ill polytrauma patients. A prospective observational non-randomized single centre study.

Being highly unstable, the critically ill polytrauma patient represents a challenge for the anaesthesia team. The aim of this study was to compare the Entropy and Surgical Pleth Index (SPI)-guided general anaesthesia with standard haemodynamic monitoring methods used in the critically ill polytrauma patients and to evaluate the incidence of hemodynamic events, as well as the opioid and vasopressor demand. 72 patients were included in this prospective observational study, divided in two groups, the ESPI Group (N = 37, patients that benefited from Entropy and SPI monitoring) and the STDR Group (N = 35 patients that benefited from standard hemodynamic monitoring). In the ESPI Group general anaesthesia was modulated in order to maintain the Entropy levels between 40 and 60. Analgesia control was achieved by maintaining the SPI levels between 20 and 50. In the STDR Group hypnosis and analgesia were maintained using the standard criteria based on hemodynamic changes. ClinicalTrials.gov identifier NCT03095430. The incidence of hypotension episodes was significantly lower in the ESPI Group (N = 3), compared to the STDR Group (N = 71) (p < 0.05). Moreover, the Fentanyl demand was significantly lower in the ESPI Group (p < 0.0001, difference between means 5.000 ± 0.038, 95% confidence interval 4.9250-5.0750), as well as vasopressor medication demand (p < 0.0001, difference between means 0.960 ± 0.063, 95% confidence interval 0.8.334-1.0866). The implementation of multimodal monitoring in the critically ill polytrauma patient brings substantial benefits both to the intraoperative clinical status and to the clinical outcome of these patients by reducing the incidence of anesthesia-related complications.

Circulating microRNAs Expressions as Genetic Biomarkers in Pancreatic Cancer Patients Continuous Non-Invasive Monitoring.

BACKGROUND: Pancreatic cancer is one of the most important causes of death worldwide. The main cause is late detection. Also, an important factor playing a role in altering the clinical status of these patients is the lack of methods for the evaluation of therapeutic response. A marker that can be useful, both in early diagnosis and in evaluating and monitoring non-invasive treatment response, is analyzing the expression of miRNAs. In this paper, we summarize genetic and epigenetic aspects of miRNAs in pancreatic cancer. Moreover, we want to emphasize potential miRNAs expressions that can be used as biomarkers for the management of patients with pancreatic cancer. METHODS: Studies available in scientific databases, such as PubMed and Scopus, were analyzed for conducting the present study. The keywords "miRNAs expression", "pancreatic cancer", and "genetic biomarkers" were used in the search engine. RESULTS: Following the searches, 187 primary scientific articles were analyzed. After rigorous analysis 40 articles were selected for the study. A high percentage of papers highlight the importance of using microRNAs as modern, non-invasive, and accurate biomarkers, designed for the early diagnosis and continuous monitoring of both the clinical outcome and treatment response of the patient. CONCLUSIONS: The expression of miRNAs can be successfully used for the evaluation and non-invasive monitoring of patients with pancreatic cancer.

The influence of metabolic imbalances and oxidative stress on the outcome of critically ill polytrauma patients: a review.

The critically ill polytrauma patient presents with a series of associated pathophysiologies secondary to the traumatic injuries. The most important include systemic inflammatory response syndrome (SIRS), sepsis, oxidative stress (OS), metabolic disorders, and finally multiple organ dysfunction syndrome (MODS) and death. The poor outcome of these patients is related to the association of the aforementioned pathologies. The nutrition of the critically ill polytrauma patient is a distinct challenge because of the rapid changes in terms of energetic needs associated with hypermetabolism, sepsis, SIRS, and OS. Moreover, it has been proven that inadequate nutrition can prolong the time spent on a mechanical ventilator and the length of stay in an intensive care unit (ICU). A series of mathematical equations can predict the energy expenditure (EE), but they have disadvantages, such as the fact that they cannot predict the EE accurately in the case of patients with hypermetabolism. Indirect calorimetry (IC) is another method used for evaluating and monitoring the energy status of critically ill patients. In this update paper, we present a series of pathophysiological aspects associated with the metabolic disaster affecting the critically ill polytrauma patient. Furthermore, we present different non-invasive monitoring methods that could help the intensive care physician in the adequate management of this type of patient.

New perspectives of volemic resuscitation in polytrauma patients: a review.

Nowadays, fluid resuscitation of multiple trauma patients is still a challenging therapy. Existing therapies for volume replacement in severe haemorrhagic shock can lead to adverse reactions that may be fatal for the patient. Patients presenting with multiple trauma often develop hemorrhagic shock, which triggers a series of metabolic, physiological and cellular dysfunction. These disorders combined, lead to complications that significantly decrease survival rate in this subset of patients. Volume and electrolyte resuscitation is challenging due to many factors that overlap. Poor management can lead to post-resuscitation systemic inflammation causing multiple organ failure and ultimately death. In literature, there is no exact formula for this purpose, and opinions are divided. This paper presents a review of modern techniques and current studies regarding the management of fluid resuscitation in trauma patients with hemorrhagic shock. According to the literature and from clinical experience, all aspects regarding post-resuscitation period need to be considered. Also, for every case in particular, emergency therapy management needs to be rigorously respected considering all physiological, biochemical and biological parameters.

Modulation of the Redox Expression and Inflammation Response in the Critically Ill Polytrauma Patient with Thoracic Injury. Statistical Correlations between Antioxidant Therapy.

BACKGROUND: One of the major causes of mortality in the world is represented by multiple traumas. Thoracic trauma is commonly associated with polytraumas. A series of physiopathological complications follow polytraumas, leading to a significant decrease in the survival rate. As a result of injuries, significant quantities of free radicals (FR) are produced, responsible for oxidative stress (OS). To minimize the effects of OS, we recommend the administration of antioxidant substances. In this study we want to highlight statistically significant correlations between antioxidant therapy and a series of clinical variables. METHODS: This retrospective study included 132 polytrauma patients admitted to the ICU-CA between January 2013 and December 2014. The selection criteria were: injury severity score (ISS) ≥ 16, ≥ 18 years, presence of thoracic trauma (abbreviated injury scale, AIS ≥ 3). Eligible patients (n = 82) were divided into two groups: Group 1 (n = 32, antioxidant free, patients from 2013) and Group 2 (n = 50 antioxidant therapy, patients from 2014). Antioxidant therapy consisted in the administration of vitamin C (i.v.), vitamin B1 (i.v.), and N-acetylcysteine (i.v.). Clinical and biological tests were repeated until discharge from ICU-CA or death. RESULTS: Between Group 1 and Group 2 statistically significant differences were highlighted regarding the ISS score (p = 0.0030). 66% of patients from Group 2 were admitted at more than 24 hours after the trauma, in contrast to the patients from Group 1, where 62.5% were directly admitted to the ICU (p = 0.0114). Compared with the patients from Group 1, patients who received antioxidant therapy show improved parameters: leukocytes (p < 0.0001), platelets (p = 0.0489), urea (p = 0.0199), total bilirubin (p = 0.0111), alanine transaminase (p = 0.0010), lactat dehydrogenase (p < 0.0001). Between the two groups there were no statistically significant differences regarding the length of stay in the ICU-CA (p = 0.4697) and mortality (p = 0.1865). CONCLUSIONS: Following the study, we can affirm that due to the administration of antioxidant substances, posttraumatic complications are greatly reduced. Moreover, the administration of high dose of antioxidants remarkably improves the clinical status of the critical patient.

Using the Expression of miRNAs as Biomarkers for the Evaluation Acute Respiratory Distress Syndrome in the Critically Ill Polytrauma Patient.

BACKGROUND: A high percentage of critically ill polytrauma patients develop acute respiratory distress syndrome (ARDS), both because of the primary traumatic injuries and because of the secondary post-traumatic injuries. For adequate management of these patients, new complex evaluation and monitoring methods are needed, methods that could answer as many questions as possible regarding the pathophysiological changes associated with ARDS. Currently, a series of clinical and biochemical markers are being used which unfortunately do not respond to the needs of an intensive care clinician. Therefore, the changes of miRNAs have been intensely researched in the case of patients with ARDS. Moreover, using them as biomarkers for ARDS brings a series of answers regarding the pathophysiological changes associated to ARDS, making them biomarkers of the future in laboratory medicine. METHODS: In order for this research study to be carried out the literature found on Scopus and PubMed on the topic was consulted, up to the year 2015. The key words used for the articles were "acute respiratory distress syndrome ARDS", "biomarkers for ARDS", "critically ill polytrauma patients", "miRNAs expression in ARDS", "miRNAs expression in sepsis", "miRNAs in critically ill patients" and "miRNAs biomarker". Research articles in English, German, and French were included in the search. RESULTS: Following the search using the above mentioned key words, 567 articles were found. After a rigorous analysis of these articles 55 of them were selected for our study. CONCLUSIONS: Using miRNAs for the evaluation and monitoring of ARDS makes them a biomarker of the future, because of the complex answers they bring to questions related both to the main injury caused by ARDS and to the associated pathophysiology.

Redox Changes Induced by General Anesthesia in Critically Ill Patients with Multiple Traumas.

The critically ill polytrauma patient is a constant challenge for the trauma team due to the complexity of the complications presented. Intense inflammatory response and infections, as well as multiple organ dysfunctions, significantly increase the rate of morbidity and mortality in these patients. Moreover, due to the physiological and biochemical imbalances present in this type of patients, the bioproduction of free radicals is significantly accelerated, thus installing the oxidative stress. In the therapeutic management of such patients, multiple surgical interventions are required and therefore they are being subjected to repeated general anesthesia. In this paper, we want to present the pathophysiological implications of oxidative stress in critically ill patients with multiple traumas and the implications of general anesthesia on the redox mechanisms of the cell. We also want to summarize the antioxidant treatments able to reduce the intensity of oxidative stress by modulating the biochemical activity of some cellular mechanisms.

Intracranial Pressure Monitoring as a Part of Multimodal Monitoring Management of Patients with Critical Polytrauma: Correlation between Optimised Intensive Therapy According to Intracranial Pressure Parameters and Clinical Picture.

OBJECTIVE: Trauma patient requires a complex therapeutic management because of multiple severe injuries or secondary complications. The most significant injury found in patients with trauma is head injury, which has the greatest impact on mortality. Intracranial pressure (ICP) monitoring is required in severe traumatic head injury because it optimises treatment based on ICP values and cerebral perfusion pressure (CPP). METHODS: From a total of 64 patients admitted in the intensive care unit (ICU) 'Casa Austria', from the Polytraumatology Clinic of the Emergency County Hospital "Pius Brinzeu" Timisoara, Romania, between January 2014 and December 2014; only patients who underwent ICP monitoring (n=10) were analysed. The study population was divided into several categories depending on the time passed since trauma to the time of installation of ICP monitoring (<18 h, 19-24 h and >24 h). Comparisons were made in terms of the number of days admitted in the ICU and mortality between patients with head injury who benefited and those who did not benefit from ICP monitoring. RESULTS: The results show the positive influence of ICP monitoring on the number of admission days in ICU because of the possibility that the number of admission days to augment therapeutic effects in patients who benefited from ICP monitoring reduces by 1.93 days compared with those who did not undergo ICP monitoring. CONCLUSION: ICP monitoring and optimizing therapy according to the ICP and CPP has significant influence on the rate of survival. ICP monitoring is necessary in all patients with head trauma injury according to recent guidelines. The main therapeutic goal in the management of the trauma patient with head injury is to minimize the destructive effects of the associated side effects.

Influence of antioxidant therapy on the clinical status of multiple trauma patients. A retrospective single center study.

INTRODUCTION: The biochemical processes of bioproduction of free radicals (FR) are significantly increasing in polytrauma patients. Decreased plasma concentrations of antioxidants, correlated with a disturbance of the redox balance are responsible for the installation of the phenomenon called oxidative stress (OS). OS action is associated with a series of secondary complications with direct implications in reducing the rate of survival, as well as in increasing morbidity The objectives of this study were to reveal possible relations between antioxidant therapy and a number of serum biochemical variables (ALT, AST, APPT, LDH, urea, leukocytes, platelets), the length of mechanical ventilation, the time spent in the ICU, and the mortality rate in major trauma patients. MATERIALS AND METHODS: In this retrospective study from a single center, 64 medical files of polytrauma patients admitted to the ICU "Casa Austria" were analysed. The selection criteria were: the Injury Severity Score (ISS) > 16 and a systolic arterial pressure (SAP) < 89 mmHg. The selected patients (n = 34) were divided into two groups: Antiox group, 20 patients who benefited from antioxidant therapy and the Contr group, 14 patients who did not received antioxidant therapy and served as a control group. The antioxidant therapy consisted of the simultaneous administration of vitamin C (i.v.), vitamin B1 (i.v.) and N-acetylcysteine (i.v.). The clinical and the biological evaluation were performed repeatedly until discharge from the ICU or the death of the patient. RESULTS: No significant differences were highlighted concerning the demographic data, the magnitude or the trauma mechanism between the two groups. In comparison with patients from the Contr group, the patients submitted to antioxidant therapy showed lower values after the treatment for leukocytes (p = 0.0066), urea (p = 0.0076), LDH (p = 0.0238), AST (p = 0.0070) and ALT (p < 0.0001). No statistically significant differences were evidenced regarding the incidence of sepsis or the development of multiple organ dysfunction syndrome (MODS). The period of mechanical ventilation was longer in patients from the Contr group (p = 0.0498), with no differences concerning the ICU length of stay (p = 0.7313). The mortality rate was lower in the Contr group (p = 0.0475). CONCLUSION: In multiple trauma patients a prolonged antioxidant therapy improved the posttraumatic laboratory tests.

Familial versus environmental factors in Balkan endemic nephropathy in Mehedinti county, Romania, by means of albuminuria and tubular biomarkers: preliminary study.

INTRODUCTION AND AIMS: Balkan endemic nephropathy (BEN), a regional tubulointerstitial kidney disease encountered in South-Eastern Europe, with still undefined etiology and inexorable evolution towards end stage renal disease, raises the question of the relative contribution of family and environmental factors in its etiology. In order to evaluate the intervention of these factors, markers of tubular injury have been assessed, this lesion being considered an early renal involvement in BEN. METHODS: The paper studies relatives of BEN patients currently included in dialysis programmes (for involvement of the family factor) and their neighbors (for involvement of environmental factors) and analyzes them with regard to tubular injury by means of tubular biomarkers (N-acetyl-beta-d-glucosaminidase-NAG and alpha-1-microglobulin), and albuminuria. At the same time, glomerular filtration rate (GFR) (CKD-EPI) was measured. It is considered that, in order to acquire the disease, one should have lived for 20 years in the BEN area. The relatives have been classified according to this criterion. RESULTS: More evident tubular injury was found in the neighbors of BEN patients living for more than 20 years in the endemic area, which argues in favor of environmental factors. Higher levels of urinary alpha-1-microglobulin and albumin in relatives of BEN patients who had been living for more than 20 years in the area than in relatives with a residence under 20 years, plead for the same hypothesis. GFR was lower in persons who had been living for more than 20 years in the BEN area (neighbors and relatives). CONCLUSIONS: Environmental factors could be more important in BEN than family factors.

Are other factors besides albuminuria important for the progression of HCV chronic hepatitis towards CKD? A survey from a hepatology department in western Romania.

UNLABELLED: HCV is an important cause of renal disease. Taal and Brenner have identified risk factors for CKD and have suggested that these risk factors be incorporated into a renal risk score analogous to the Framingham cardiovascular score. Given the high HCV-renal disease comorbidity, we sought to assess risk factors for CKD in patients with HCV chronic hepatitis. METHODS: One hundred-seventeen patients with HCV chronic hepatitis (mean age: 50.68 +/- 9.14 years; 86 female and 31 male) hospitalized in the Department of Hepatology during 2009 were enrolled into the study. All patients were assessed for the risk factors for CKD proposed by Taal and Brenner: albuminuria, diabetes mellitus, hypertension, obesity, anemia, hypercholesterolemia, hypertriglyceridemia, nephrotoxins, primary renal disease, associated urological disorder, cardiovascular disease and family history of CKD. Renal function (GFR-CKD-Epi) was also evaluated. STATISTICAL ANALYSIS: Pearson's correlation coefficient and Odds Ratio (OR) was performed using SPSS17 and Epi 3.2.2. RESULTS: The prevalence of albuminuria was 21.36%, of hypertension was 20.51%, of obesity was 21.36%, and hypercholesterolemia was present in 41.02% of the cases. Renal function was as follows: 10.25% (12/117) of the patients had a GFR < 60 mL/min/1.73 sqm.; 64.95% (76/117) of the patients had a GFR between 60-89 mL/min/1.73 sqm.; and 24.78% (29/117) had a GFR > or = 90 mL/min/1.73 sqm. CONCLUSIONS: Our study shows that HCV chronic hepatitis is associated with renal function impairment in a high percentage of patients. Prominent risk factors for CKD are present in these patients, such as albuminuria, hypertension, obesity, and hypercholesterolemia, which need to be actively searched and addressed therapeutically.

Prostate cancer molecular detection in plasma samples by glutathione S-transferase P1 (GSTP1) methylation analysis.

BACKGROUND: Prostate cancer (PCa) represents the most commonly diagnosed type of malignancy among men in Western European countries and the second cause of cancer-related deaths among men worldwide. Methylation of the CpG island has an important role in prostate carcinogenesis and progression. The purpose of the study was to analyse the diagnostic value of aberrant promoter hypermethylation of the gene for glutathione S-transferase P1 (GSTP1) in plasma DNA to discriminate between prostate cancer (PCa) and benign prostatic hyperplasia (BPH) patients by minimally invasive methods. METHODS: Aberrant promoter hypermethylation was investigated in DNA isolated from plasma samples of 31 patients with diagnostic of PCa and 44 cancer-free males (control subjects). Extracted genomic DNA was bisulfite treated and analyzed using methylation-specific polymerase chain reaction (MS-PCR) technique. RESULTS: Hypermethylation of the GSTP1 gene was detected in plasma samples from 27 of 31 (92.86%) patients with PCa. Genomic DNA from plasma samples from the 44 controls without genitourinary cancer revealed promoter hypermethylation of GSTP1 gene in 3 (10.6%) of the 44 patients. Receiver operating curve (ROC) included clinico-pathological parameters such as: serum PSA levels, pathological stage, Gleason score, hypermethylation status of GSTP1 gene, and it gave a predictive accuracy of 93% with a sensitivity and specificity of 95% and 87%, respectively. CONCLUSIONS: In this study, we have evaluated the ability of GSTP1 gene to discriminate between PCa and BPH patients in genomic DNA from plasma samples by non-invasive methods.

Is There any Difference Between the Glomerular Filtration Rate of Patients With Chronic Hepatitis B and C and Patients With Cirrhosis?

BACKGROUND: Renal dysfunction is a major determinant of the Model of End-stage Liver Disease (MELD) score. The implementation of the MELD score has shifted allocation of livers to patients with renal dysfunction. OBJECTIVES: The aim of our study was the assessment of estimated Glomerular Filtration Rate (eGFR) by the Modification of Diet in Renal Disease 4 (MDRD4) method in patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis (CH) caused by these viruses to detect any differences in renal function among these diseases. PATIENTS AND METHODS: We performed a cross-sectional analysis of all consecutive patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis caused by these viruses hospitalized during a 4 year period in the Gastroenterology and Hepatology department of the Emergency County Hospital Timisoara, Romania. The eGFR was assessed by the MDRD4 method. Statistical analysis (unpaired t-test, ANOVA, Chi Square test) was performed using OpenEpi 2.3.1. RESULTS: HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the GFR. The eGFR was higher in patients with HBV chronic hepatitis than in patients with HCV chronic hepatitis (P < 0.001). Patients with cirrhosis secondary to HBV infection had a higher eGFR than patients with cirrhosis secondary to HCV (P = 0.01). The eGFR of patients with HCV chronic hepatitis was higher than the eGFR of patients with cirrhosis due to this virus (P < 0.001). CONCLUSIONS: Functional renal impairment in diseases caused by HCV was more important than in diseases caused by HBV. The eGFR was statistically lower in cirrhosis secondary to HCV than in HCV chronic hepatitis.
