RESUMO

Prostate cancer (PC) represents the second most frequent cancer diagnosis in men and, at the same time, is one of the top six causes of death worldwide. The aim of the present study was to evaluate the diagnostic value of glutathione-S-transferase gene P1 (GST-P1) in patients that fall within the 'grey area' of the prostate-specific antigen (PSA) values. A retrospective observational study on 80 patients with prostate abnormal volumes and PSA values in the range 4-10 ng/ml was performed. The prostate gland was extracted following transrectal ultrasonography, and GST-P1 gene expression was analysed. A histopathological examination was considered the gold standard for PC diagnosis. Among the 53 patients diagnosed with PC, 69.8% (n=37) were GST-P1-positive, whereas, among the 27 patients diagnosed with benign prostatic hyperplasia, 18.5% (n=5) were GST-P1-positive. The sensitivity for diagnosing PC in patients with PSA values between 4 and 10 ng/ml was 69.81%, and the specificity was 81.48%. The positive predictive value was 88.1% [95% confidence interval (CI), 74.37-96.02%] and the negative predictive value was 57.89% (95% CI, 40.82-73.69%). Collectively, these results show the potential of using GST-P1 gene expression in patients who are suspected of having PC, but where the PSA values are inconclusive.

RESUMO

Balneotherapy, a branch of physical and rehabilitation medicine using the natural factors of balneal resorts for therapeutical purposes to modulate the symptoms of numerous diseases, represents a non-pharmaceutical therapeutic alternative, easily accepted by patients and used both preventively and curatively. Crenotherapy, a branch of balneotherapy, is the method in which mineral waters are used as a therapeutic internal cure by ingestion. This procedure is performed in spa resorts (where these natural resources exist), and the ingestion of mineral water takes place at the source (spring), in the quantities recommended by the medical rehabilitation physician, according to specific regimens for the condition to be treated. Depending on their physical and chemical composition, the therapeutic mineral waters fall into several categories, having clear indications for certain pathologies. Hypotonic, isotonic, or slightly hypertonic mineral waters are recommended in diseases of the digestive tract and hepatobiliary conditions. Over time, studies have been conducted to determine the effect of these types of treatments, highlighting the complex influence of crenotherapy on the gastrointestinal tract, with favorable results, therefore the use of mineral water intake in various pathologies being recommended. The current review focuses on the existing literature data and refers to the main progress made in understanding the benefit, indications, and crenotherapy procedures in the management of gastrointestinal disorders.

RESUMO

The aim of the present study conducted on the lumbar spine was to confirm that the pronounced decrease in resistance in the system is a phenomenon that can be eminently affected by the adaptive changes that occur at the level of the intervertebral disc at axial mechanical stresses. The biomechanical trial was carried out on 11 lumbar segments L1-L5, gathered from adult human cadavers. The dissection considered the complete keeping of all bone, disc, articulated and ligamentous components in their anatomical position. All 11 samples were frozen 24 h prior to the performance of the biomechanical measurement. The specimens were placed in the testing device, their placement being conditioned by the estimated dimensional values. Thus, to calculate the load and axial resistance, the models were placed vertically, central between the test machine ferries. The testing was carried out by applying variable forces and displacement supervision. The displacement interval was represented by a segment of 0-10 mm with surveillance every 2 mm. Mobility in the sagittal plane (flexion earlier in our case) was much higher than that in the frontal plane, obviously limiting mobility via the intervertebral disc and articular complex through the presence of arches. Statistical analysis demonstrated the lack of any correlation values between the two types of movements (R2=0.005507), underlining the absence of any prediction elements. A noteworthy aspect is that the correlations appeared low, statistically insignificant, even within the same movement in the sagittal plane between the two levels, L1-L3 and L3-L5 (R2=0.610427), which may lead to the possibility of the emergence of significant differences in mobility between respective levels. The behavior type of the monitored specimens and the results obtained allowed the mapping of objective parallelism between the values obtained and the behavior in vivo of the lumbar vertebral segment.

RESUMO

Spontaneous bacterial peritonitis (SBP) is a severe complication of liver cirrhosis whose diagnosis is based on a polymorphonuclear leukocyte (PMN) value >250 mm3, yet this PMN value cannot identify all existing types. The aim of our study was to determine the clinical and biological factors that were associated with SBP and predict its occurrence, focusing on the neutrophil-to-lymphocyte ratio (NLR) as one of them. Our retrospective study included 216 patients with liver cirrhosis who were hospitalized between December 2019 and January 2010 at the Emergency County Clinical Hospital of 'St. Apostle Andrew' in Constanta, Romania. Demographic, clinical, and laboratory data were collected from patient observation sheets. The patients were divided into two groups: One group of patients with SBP and the other without SBP. The diagnosis of SBP was made when patients presented with PMN >250 mm3 and other causes of secondary bacterial peritonitis were excluded. The mean age of the patients was 61.25±10.67 years, and the alcoholic etiology of liver cirrhosis was most common (44%). Univariate logistic regression analysis showed that there was an association between biological parameters, such as serum white blood cells, total platelet count, total bilirubin, serum albumin, international normalized ratio, creatinine, erythrocyte sedimentation rate (ESR), serum sodium, alkaline reserve, and NLR, and clinical parameters, such us upper gastrointestinal bleeding and cardiac comorbidities in the occurrence of SBP. Multivariate analysis identified ESR and NLR as predictive factors in the occurrence of SBP. The area under the curve (AUC) was 0.916 [P<0.001, 95% confidence interval (CI) 0.870-0.949] for ESR and AUC was 0.963 (P<0.001, 95% CI 0.928-0.984) for NLR, respectively. In conclusion, the combination of these 2 biological parameters is useful in identifying or excluding SBP.

RESUMO

Spontaneous bacterial peritonitis (SBP) is a complication of liver cirrhosis with an increased in-hospital mortality rate. For this reason, the aim of the present study was to examine the main predictors of mortality in order to be able to identify high-risk patients in time and to guide the optimal treatment for prognosis improvement. We retrospectively collected demographic, clinical, laboratory and treatment data as well as data regarding length of stay and cost of hospitalization from 72 patients diagnosed with SBP between January 2010 and December 2019 in the Emergency Clinical Hospital St. Apostle Andrew, Constanta, Romania. Patients were divided into two groups: Those who survived and those who died. Logistic regression was used to identify a possible association between these factors and the increased risk of mortality. Univariate analysis revealed that clinical factors (fever, chills, and hepatic encephalopathy), biological factors such as serum and ascites leukocyte value, polymorphonuclear percentage (PMN), erythrocyte sedimentation rate (ESR) value, previous SBP episodes, and the presence of complications such as acute kidney injury (AKI), sepsis, and systemic inflammatory response syndrome (SIRS) were significantly associated with in-hospital mortality in patients with SBP. Multivariate analysis revealed that SIRS (P=0.0010) and fever (P=0.0258) were significantly associated with in-hospital mortality in patients with SBP. Findings of the present study suggest that, SIRS and fever were independent predictive factors of mortality in cirrhotic patients with SBP.

RESUMO

Epidemiological data regarding hepatocellular carcinoma (HCC) report unsatisfactory morbimortality rates despite the global efforts to decrease the incidence and prolong patient survival. Current guidelines lack diagnostic biomarkers to better characterize patients with HCC. We aimed to validate the overexpression of Survivin-1, tumor-associated glyocoprotein 72 (Tag-72), and HECT and RLD domain containing E3 ubiquitin protein ligase 5 (HERC5) as tissue biomarkers for HCC characterization in patients from our geographical area and to standardize a local biomarker panel to be introduced in the current management guideline. Thirty samples of histologically confirmed HCC were compared to an equal number of samples of benign tumors in terms of Survivin-1, TAG-72, and HERC5 overexpression. Student's t-test, Mann-Whitney U test and Chi-square test were used to find differences between the two studied groups and to compare the categorical variables. The discriminative power of Survivin-1, Tag-72, and HERC5 overexpression was assessed using ROC curves. The multivariate linear regression analysis revealed that Survivin, Tag-72, and HERC5 were significantly overexpressed in older male patients, with α-fetoprotein (AFP) >200 ng/dl, low serum albumin, as well as in patients with imaging features of portal thrombosis and ascites. The diagnostic performance of Survivin-1, Tag-72 and HERC5 tissue biomarkers for HCC characterization was superior to that of the gold-standard AFP. Our study results validate the overexpression of Survivin-1, Tag-72, and HERC5 as tissue biomarkers for HCC characterization in patients from our geographical region and could be standardized in the current HCC management guideline.

RESUMO

The coronavirus disease (COVID)-19 pandemic is a major challenge for the health systems worldwide. Acute respiratory distress syndrome (ARDS), is one of the most common complications of the COVID-19 infection. The activation of the coagulation system plays an important role in the pathogenesis of ARDS. The development of lung coagulopathy involves thrombin generation and fibrinolysis inhibition. Unfractionated heparin and its recently introduced counterpart low molecular weight heparin (LMWH), are widely used anticoagulants with a variety of clinical indications allowing for limited and manageable physio-toxicologic side effects while the use of protamine sulfate, heparin's effective antidote, has made their use even safer. Tissue-type plasminogen activator (tPA) is approved as intravenous thrombolytic treatment. The present narrative review discusses the use of heparin and tPA in the treatment of COVID-19-induced ARDS and their related potential physio-toxicologic side effects. The article is a quick review of articles on anticoagulation in COVID infection and the potential toxicologic reactions associated with these drugs.

RESUMO

Metabolomics, the research area studying chemical processes involving metabolites, finds its utility in inflammasome biomarker discovery, thus representing a novel approach for cardiometabolic syndrome pathogeny acknowledgements. Metabolite biomarkers discovery is expected to improve the disease evolution and outcome. The activation of abundantly expressed NLRP3 inflammasome represents the background process of the diabetes mellitus disturbances like hyperglycemia and insulin resistance, as well as for myocardial cell death and fibrosis, all of them being features characteristic for cardiometabolic syndrome. Many molecules like troponins, brain natriuretic protein (BNP), ST2/IL-33, C-reactive protein (CRP), TNF, IL-1ß, and IL-18 cytokines have been already examined as molecular markers for diagnosing or predicting different cardiac disturbances like myocardial infarction, heart failure, or myocarditis. In addition, metabolomics research comes with new findings arguing that NLRP3 inflammasome becomes a promising molecular tool to use for clinical and therapeutical management providing new targets for therapies in cardiometabolic syndrome. Inflammasome markers analyses, along with other molecular or genetic biomarkers, will result in a better understanding of cardiometabolic syndrome pathogenesis and therapeutic targets. Screening, diagnostic, and prognostic biomarkers resulted from inflammasome biomarker research will become standard of care in cardiometabolic syndrome management, their utility becoming the first magnitude.

RESUMO

Direct oral anticoagulants (DOACs) such as apixaban or dabigatran are excellent options in preventing embolic cardiovascular events. Observational studies have shown that gastrointestinal bleeding risks produced by DOACs could be lowered when correcting some host co-factors i.e. Helicobacter pylori (HP) infection. The upper digestive bleeding (UDB) rates in patients with DOAC indication and the usefulness of anti-HP therapy addition were compared. An observational retrospective study was conducted of medical records of 260 patients treated with DOACs, 130 of whom were concomitantly treated for HP infection in accordance with Maastricht V/Florence consensus. The severity of bleeding, the complexity of endoscopic treatment required to stop the bleeding, the re-bleeding rates, the surgical treatment indication and the overall mortality rates were compared between the groups. The risk of UDB was higher in HP-untreated patients in both types of DOACs used (respectively 2.08, 2.02). HP-untreated Forrest Ia/Ib/IIa and IIb DOACs patients had more severe bleedings compared with same class of HP-treated patients (P=0.007/0.005; 0.009/0.006; 0.048/0.005, 0.044/0.049, respectively). Endoscopic treatments such as adrenaline injections combined with metallic clip attachments were more frequently mandatory in HP-untreated DOACs patients for classes Ia/b and IIa (respectively, P=0.000/0.001, P=0.003/0.003). The re-bleeding rates were higher in HP-untreated patients with concomitant DOACs (OR 82.5; 95% CI 30.1-121.7; P=0.005). A history of peptic ulcer or UDB was associated with a 2.9-fold higher risk of UDB in HP-untreated compared with HP-treated patients, slightly increased for dabigatran compared with apixaban (RR 3.06, 2.72, P<0.5, respectively). Surgical intervention and the UDB-related mortality rates were higher in HP-untreated patients (P=0.041/0.044, P=0.007, respectively). HP-eradication treatment and bacterial clearance improve the safety profile of DOACs treatment, especially in fragile patients, in whom the UDB rates can be lowered, and the overall outcome can be enhanced by this combined approach.

RESUMO

Cutis laxa (CL) or elastolysis is a rare inherited or acquired connective tissue disorder in which the skin becomes inelastic and hangs loosely in folds (Mitra et al., 2013). The clinical presentation and the type of inheritance show considerable heterogeneity (Shehzad et al., 2010). We aimed to present the atypical case of a young male patient diagnosed at 36-year-old with CL with systemic involvement. The complex medical history, with a suspected but unconfirmed progeria at nine months, repeated lung and urinary infections, complicated inguinoscrotal hernia, prostatic hypertrophy, bilateral entropion, colorectal diverticula and heart failure, suggested a systemic genetic disease, but the absence of family history made the diagnosis of CL difficult. The skin biopsy and the characteristic features discovered during anatomopathological exam made possible the positive and differential diagnosis, creating the link between the various organ involvement and CL diagnosis. Because of the age of our patient, of normal growth and mental development, and negative family history, we suspected an autosomal dominant form of CL with early onset and severe manifestation. Of course, we cannot exclude a recessive form, due to the heterogeneity of this disease.
