RESUMO

Background/Objectives: The newly emergent COVID-19 pandemic involved primarily the respiratory system and had also major cardiovascular system (CVS) implications, revealed by acute myocardial infarction (AMI), arrhythmias, myocardial injury, and thromboembolism. CVS involvement is done through main mechanisms-direct and indirect heart muscle injury, with high mortality rates, worse short-term outcomes, and severe complications. AMI is the echo of myocardial injury (revealed by increases in CK, CK-MB, and troponin serum markers-which are taken into consideration as possible COVID-19 risk stratification markers). When studying myocardial injury, physicians can make use of imaging studies, such as cardiac MRI, transthoracic (or transesophageal) echocardiography, coronary angiography, cardiac computed tomography, and nuclear imaging (which have been used in cases where angiography was not possible), or even endomyocardial biopsy (which is not always available or feasible). Two-case-series presentations: We present the cases of two COVID-19 positive male patients who were admitted into the Clinical Department of Cardiology in "Sfântul Apostol Andrei" Emergency Clinical Hospital of Galați (Romania), who presented with acute cardiac distress symptoms and have been diagnosed with ST elevation AMI. The patients were 82 and 57 years old, respectively, with moderate and severe forms of COVID-19, and were diagnosed with anteroseptal left ventricular AMI and extensive anterior transmural left ventricular AMI (with ventricular fibrillation at presentation), respectively. The first patient was a non-smoker and non-drinker with no associated comorbidities, and was later discharged, while the second one died due to AMI complications. Conclusions: From this two-case series, we extract the following: old age alone is not a significant risk factor for adverse outcomes in COVID-19-related CVS events, and that the cumulative effects of several patient-associated risk factors (be it either for severe forms of COVID-19 and/or acute cardiac injury) will most probably lead to poor patient prognosis (death). At the same time, serum cardiac enzymes, dynamic ECG changes, along with newly developed echocardiographic modifications are indicators for poor prognosis in acute cardiac injury in COVID-19 patients with acute myocardial injury, regardless of the presence of right ventricular dysfunction (due to pulmonary hypertension).

RESUMO

Background/Objectives: The objective of this study was to analyze the results of clinical trials regarding long-term antiviral therapies in chronic hepatitis with HBV to compare current therapeutic protocols and to analyze the results of preliminary studies with new antiviral therapies for HBV. Methods: Clinical studies and meta-analyses from PubMed, Google Scholar, and Research Gate from 2011 to 2024 were analyzed on patients undergoing chronic antiviral therapy for HBV, and a retrospective observational study performed in our clinic on a group of 76 patients undergoing chronic therapy with entecavir was presented. Also, a summary of the results of preliminary studies with various innovative antiviral molecules for HBV was performed. Results: The results of extensive clinical trials reveal that current therapies for chronic HBV are well tolerated and maintain good viral suppression if the patient is adherent to therapy. Innovative therapies aim to eliminate HBsAg and, thus, significantly shorten the duration of treatment, and the preliminary results of the studies are promising. Conclusions: Being an asymptomatic condition that requires life-long therapy, adherence to therapy is a real problem. Also, the risk of decompensation of liver cirrhosis and adenocarcinoma remains important in these patients. Future research is needed to perfect some antiviral therapy schemes that shorten the treatment period but also decrease the rate of progression towards decompensated cirrhosis and liver adenocarcinoma.

RESUMO

BACKGROUND: Heart failure is a global major healthcare problem with millions of hospitalizations annually and with a very high mortality. There is an increased interest in finding new and reliable biomarkers for the diagnostic, prognostic and therapeutic guidance of patients hospitalized for acute heart failure; Our review aims to summarize in an easy-to-follow flow recent relevant research evaluating the possible use and the clinical value of measuring CA 125 serum levels in acute HF. METHODS: A thorough search in the main international databases identified a relevant pool of 170 articles, providing recently published data for this narrative review that used PRISMA guidelines. RESULTS: There are data to sustain the role of carbohydrate antigen 125 (CA 125), a worldwide used marker of ovarian cancer, in patients with heart failure. Several studies have shown links between CA 125 levels and congestion seen in acute heart failure, high mortality and readmission rates at 6 months follow-up after discharge from acute heart failure and also a role of CA 125 in the guidance of heart failure therapy. There are also clinical trials that showed that several particularities of CA 125 make it even better than N-terminal pro b-type natriuretic peptide (NT-pro BNP)-a classical and more utilized marker of heart failure) in several scenarios of acute heart failure. CONCLUSIONS: Although the mechanism behind the upregulation of serum CA 125 in patients with congestive HF has not been confirmed nor fully understood.

RESUMO

Chromophobe renal cell carcinoma (CRCC) is a distinct subtype of renal cell carcinoma with unique histological, immunohistochemical, cytogenetic, and ultrastructural features, which usually has a favorable clinical course, with only a small percentage of patients developing recurrence, metastasis, or death due to its complications. Sarcomatoid differentiation can occur in any subtype of renal cell carcinoma and currently represents the transformation into a higher degree of malignancy, its presence being associated with a reserved prognosis, with a reported incidence of average survival of less than 1 year after diagnosis. In this study, we present an unusual case of CRCC with massive sarcomatoid differentiation, which infiltrated the left adrenal gland and was surgically resected. The histological features of this tumor as well as a brief review of literature are presented.

RESUMO

INTRODUCTION: The aim of this study is to evaluate the results of online group meetings for breast cancer patients in the active phase of treatment. The group therapy sessions took place weekly, synchronously, online, on Zoom, with a total of 12 meetings lasting about 2.5 h per session, between December 2021 and February 2022. We analyzed the topics of discussion chosen by the participants, the structure of the group, the results obtained at the main scales of evaluation/monitoring of quality of life and the motivation of patients to participate in the therapeutic group. All patients were in the active phase of treatment (chemotherapy, radiotherapy, hormone therapy, etc.). The main goal of the group therapy was to reduce the stress related to the disease. MATERIAL AND METHODS: Systematic observations included ABS psychological tests, EQ-5D-5L, HADS-Hospital Anxiety and Depression Scale, and the Recurrence Fear Questionnaire; the questionnaires were administered at the beginning and at the end of the therapeutic intervention; the participation in the therapy and in the research of the patients began after signing the informed consent document; the intervention was evaluated at the end using a feedback questionnaire. The group was closed, and the participants signed an informed consent document and agreed to have the sessions recorded. RESULTS: Comparing the initial with the final results of the psychological tests administered, there was an improvement in the quality of life of the participants in all areas, with a clinically significant decrease in the areas of pain and depression, along with an increase in perception of well-being, a decrease in FoP scores and an increase in the level of rationality about the disease. CONCLUSIONS: Group therapy for cancer patients was useful in improving the quality of life; the closed group, even online, provided a safe environment in which they could share feelings. A close correlation was noted between the scores obtained on the FoP-Q and HADS scales. It is evident that there is a strong relationship between FoP and depression. Results on these scales correlated well with results on the EQ-5D-5L quality of life questionnaire.

RESUMO

Basal cell carcinoma (BCC) is a malignant tumor with a rising incidence and is the beneficiary of several innovative evaluation techniques. Histopathology remains the gold standard for assessment, having the possibility of addressing multiple high-risk factors such as perineural invasion (PNI). The current study included a number of 244 BCC patients and targeted the identification of positive PNI and its suggestive signs, and whether they correlated or not with other high-risk tumor signs. PNI was found in 20.1% of patients, with 30.7% of patients having perineural chronic inflammation (PCI), which is a suggestive sign of PNI. PNI was also found in larger tumors, with deeper Clark levels, in high-risk BCCs and high-grade tumors. PNI and PCI are both important for pathology reporting, aiding in treatment choice and further patient management, with possibly positive outcomes concerning morbidity and mortality.

RESUMO

Background and Objectives: Preterm birth (PTB) is associated with important neonatal mortality and morbidity. The aim of this study was to retrospectively evaluate the average treatment effects on the treated and the efficacity of various therapeutic interventions for PTB in a cohort of patients with singleton pregnancies and short cervical lengths. Materials and Methods: This observational retrospective study included 1146 singleton pregnancies at risk of PTB that were segregated into the following groups: intravaginal progesterone (group 1), Arabin pessary (group 2), McDonald cerclage (group 3), intravaginal progesterone and Arabin pessary (group 4), and intravaginal progesterone and cerclage (group 5). Their treatment effects were evaluated and compared. Results: All evaluated therapeutic interventions significantly reduced the occurrence of late and early preterm births. The risk of late and early PTB was lowered for those pregnant patients who received progesterone and pessaries or progesterone and cerclage in comparison with those who received only progesterone. The extremely PTB risk of occurrence was significantly lowered only by the administration of progesterone in association with cervical cerclage in comparison with progesterone monotherapy. Conclusions: The combined therapeutic interventions had the highest efficacy in preventing preterm birth. An individualized evaluation is needed to establish the best therapeutic approach in particular cases.

RESUMO

Heart failure is one of the main morbidity and mortality factors in the general population and especially in elderly patients. Thus, at the European level, the prevalence of heart failure is 1% in people under 55 years of age but increases to over 10% in people over 70 years of age. The particularities of the elderly patient, which make the management of heart failure difficult, are the presence of comorbidities, frailty, cognitive impairment and polypharmacy. However, elderly patients are under-represented in clinical trials on the diagnosis and treatment of heart failure. The need for complementary methods (biomarkers) for differential and early diagnosis of heart failure is becoming more and more evident, even in its subclinical stages. These methods need to have increased specificity and sensitivity and be widely available. Natriuretic peptides, in particular B-type natriuretic peptide (BNP) and its fraction NTproBNP, have gained an increasingly important role in the screening, diagnosis and treatment of heart failure in recent years.

RESUMO

Background and Objectives: Fetal ovarian cysts (FOCs) are a very rare pathology that can be associated with maternal-fetal and neonatal complications. The aim of this study was to assess the influence of ultrasound characteristics on FOC evolution and therapeutic management. Materials and Methods: We included cases admitted to our perinatal tertiary center between August 2016 and December 2022 with a prenatal or postnatal ultrasound evaluation indicative of FOC. We retrospectively analyzed the pre- and postnatal medical records, sonographic findings, operation protocols, and pathology reports. Results: This study investigated 20 cases of FOCs, of which 17 (85%) were diagnosed prenatally and 3 (15%) postnatally. The mean size of prenatally diagnosed ovarian cysts was 34.64 ± 12.53 mm for simple ovarian cysts and 55.16 ± 21.01 mm for complex ovarian cysts (p = 0.01). The simple FOCs ≤ 4 cm underwent resorption (n = 7, 70%) or size reduction (n = 3, 30%) without complications. Only 1 simple FOC greater than 4 cm reduced its size during follow-up, while 2 cases (66.6%) were complicated with ovarian torsion. Complex ovarian cysts diagnosed prenatally underwent resorption in only 1 case (25%), reduced in size in 1 case (25%), and were complicated with ovarian torsion in 2 cases (50%). Moreover, 2 simple (66.6%) and 1 complex (33.3%) fetal ovarian cysts were postnatally diagnosed. All of these simple ovarian cysts had a maximum diameter of ≤4 cm, and all of them underwent size reduction. The complex ovarian cyst of 4 cm underwent resorption during follow-up. Conclusions: Symptomatic neonatal ovarian cysts, as well as those that grow in size during sonographic follow-up, are in danger of ovarian torsion and should be operated on. Complex cysts and large cysts (with >4 cm diameter) could be followed up unless they become symptomatic or increase in dimensions during serial ultrasounds.

RESUMO

Psoriatic arthritis is a significant medical condition with a high prevalence, a wide variety of non-specific symptoms, and a high degree of overlap with other spondylarthritis disorders, particularly ankylosing spondylitis. Hence, knowledge of the magnetic resonance imaging (MRI) manifestations and a multidisciplinary strategy are required for the better management of these patients. We searched publications from the last 10 years and focused on the most relevant ones which discussed the classification criteria, the MRI characteristics of axial psoriatic arthritis, the importance of MRI for follow up, and the reliability of skin and synovial biopsy. Axial spondylarthritis can be diagnosed and followed up on using the well-established MRI technique and, additionally, a biopsy. The analysis and concordance between them can provide new directions for future studies.

RESUMO

(1) Background: This study aimed to outline the antioxidant, antitumoral, and cytotoxic proprieties of various types of Perilla frutescens extracts obtained from the leaves of the species. (2) Methods: We determined total polyphenols, flavonoids and anthocyanins contents, as well as the in vitro antioxidant, antitumoral, and cytotoxic actions in three types of ethanolic extracts (E1, E2, E3) and in three types of acetone: ethanol extracts (A1, A2, A3) of Perilla frutescens according to standardized procedures. (3) Results: We found that Perilla frutescens ethanolic extracts had the highest total phenol and anthocyanins concentrations. The flavonoids concentration was not statistically different between the extracts. The iron chelating capacity, hydroxyl radical scavenging capacity, superoxide anion radical scavenging capacity, and lipoxygenase inhibition capacity showed a significant increase with higher concentrations of Perilla frutescens extracts, particularly the ethanolic extracts. Perillyl alcohol had greater cytotoxic capacity in the MG-63 cell line and E1 extract showed similar significant cytotoxic effects in the A431 cell line. (4) Conclusions: Both ethanolic and acetone-ethanol extracts from Perilla frutescens exhibited important antioxidant and antitumoral actions in vitro, which proportionally increased with concentration. The cytotoxic threshold determined in this study for various types of extracts could help determine the best dosage with the maximum antioxidant and antitumoral potential. Our results could serve as a basis for further studies that will investigate the cytotoxic effects of Perilla frutescens variants on various types of cancer cell lines.

RESUMO

Neurofibromatosis type 1 (NF1) or von Recklinghausen disease is one of the most common autosomal dominant genetic diseases. It is characterized by 'café-au-lait' spots and multiple tumors starting from the central and peripheric nervous system. The diagnosis is determined on two out of seven criteria: i) A total of 6 or more light brown spots larger than 5 mm in diameter (pre-puberty) or 15 mm in diameter (post-puberty); ii) a total of 2 or more neurofibromas or one plexiform neurofibroma; iii) axillary or inguinal freckling; iv) optic glioma; v) a total of 2 or more Lisch nodules; vi) bone abnormalities: tibia pseudarthrosis or dysplasia of the sphenoid wing; and vii) a relative of first degree having an NF1 diagnosis. A total of ~50% of patients have significant musculoskeletal manifestation, with scoliosis and congenital pseudarthrosis of tibia most common. Management of the orthopaedic manifestations of NF1 is often difficult. Due to NF1 influencing multiple organ systems, patients are likely to benefit most from a multidisciplinary treatment strategy.

RESUMO

Lung cancer is the main cause of oncological death in the US and worldwide, constituting a significant public health problem. The incidence of lung cancer is on the increase. In the present study, the diagnostic process was carried out and treatment options were considered to determine the therapeutic response of a patient diagnosed with lung cancer. The case of an early stage lung cancer patient who benefited from surgical treatment was presented. The pathology report stated the complete diagnosis to be pleomorphic lung cancer with an adenocarcinoma component, pT2aN0M0, with focal positivity for thyroid transcription factor 1 (TTF1), without epidermal growth factor receptor (EGFR) mutations and ALK recombinations, having an initial clinical stage of IB and programmed death ligand-1 (PD-L1) positivity with a tumor proportion score of over 70%. The patient underwent radiotherapy treatment and was administered osteoclast inhibitors and immunotherapy, with no favorable therapeutic effect and with the presence of secondary cutaneous adverse effects to pembrolizumab. As a main cause of death, lung cancer registers a low general survival rate even in patients with targeted therapies or immunotherapy. By better identifying the patients at risk, one can establish a more efficient personalized treatment; the future objective of scientific studies is the follow-up of adverse effects of new therapies.

RESUMO

Gadolinium (symbol Gd) is the chemical element with atomic number 64 and is aductile rare-earth metal, and +3 is its most frequent oxidation state. Gadolinium has an ionic radius of 0.99 Å and is nearly identical to the one of Ca2+. Gd3+ and Ca2+ can become toxic to biological systems if complete. It slowly reacts with atmospheric oxygen to form a black coating and in nature it is usually found only in an oxidized form. Gadolinium usually has impurities similar to those of other rare-earth metals, when separated, because of their similar chemical properties. Neurofibromatosis type 1 (NF1) or von Recklinghausen's disease is an autosomal dominant disorder of tissues of ectodermal origin, accounting for over 90% of neurofibromatosis cases. Diagnosis is primarily clinical and the central nervous system is commonly involved. The screening of the brain with magnetic resonance (MR) imaging is utilised to evaluate the patients with neurofibromatosis type 1 and as an aid in the diagnosis of asymptomatic patients when clinical criteria are not met.

RESUMO

Interleukin 6 (IL-6), a cytokine produced by various cells of the human body (macrophages, lymphocytes, astrocytes, ischemic myocytes, endothelial cells) has both pro-inflammatory and anti-inflammatory properties, being a key component in regulating various physiologic and pathological processes. The structure of this molecule and the receptor system it possesses are important due to the different activities that IL-6 can exert; through trans-signaling pro-inflammatory activities are mediated, while through classic signaling, IL-6 is responsible for anti-inflammatory and regenerative activities. IL-6 signaling is involved in coronary artery disease and the global COVID-19 pandemic. This proatherogenic cytokine reaches elevated serum levels in the cytokine storm generated by SARS-CoV-2, and is also associated with smoking or obesity-classic cardiovascular risk factors which promote inflammatory states. IL-6 levels are proportionally correlated with dyslipidemia, hypertension and glucose dysregulation, and they are associated with poor outcomes in patients with unstable angina or acute myocardial infarction. IL-6 targeting for treatment development (not only) in cardiovascular disease and COVID-19 is still a matter of ongoing research, although tocilizumab has proven to be effective in reducing the proatherogenic effects of IL-6 and is suggested to improve COVID-19 patient survival.

RESUMO

Psoriatic arthritis is a chronic inflammatory condition that can lead to severe functional impairment and irreversible damage. The diagnosis can be difficult in early cases where the clinical exam is often scarce. The lack of a serological biomarker can lead to a considerable delay in diagnosis. In this review, we discuss the existent imaging methods that have improved the diagnosis of psoriatic arthritis (PsA). The degree and type of musculoskeletal involvement cannot be assessed by only one imaging method. We think that a combination of methods is the best approach to evaluate both structural damage and inflammatory lesions and that ultrasound (US) could be the best tool to screen a patient when considering the diagnosis of PsA. US is an accessible, non-ionizing technique that offers information regarding active inflammation in joints, entheses, and soft tissues.

RESUMO

Twenty-two cases with gastrointestinal stromal tumors (GISTs) have been studied, sized from 2 cm to invasive gigantic tumors and also from low to high degree of malignancy. The altering of the form and the size of the nucleus is a reference point of malignancy, being used in the histological grading of many types of tumors and also as an appreciating parameter of the tumoral prognosis, with a high degree of accuracy in the colorectal, uterine, prostatic or ovarian cancers, as it was pointed in the previous researches. The aim of this study is to evaluate the dimensional characteristic of the nuclei and the mitosis in GIST with a cholic and gastric localization, attempting a quantitative differentiation of the two tumors, by studying the following aspects: nuclear dimensions, mitotic activity index and the mitotic density. The results of the proliferative activity quantification (mitotic activity index and mitotic density) have shown that this can be a decisive criterion for the precocious appreciation of the evolution. The most important morphological criterion with a predictive role is the mitotic activity index, but is recommended to be applied correlated with the size and the localization of the tumor. Although various nuclear morphometry studies in different types of malignant tumors have been performed, the data in gastrointestinal stromal tumors is scarce and only few similar studies have been reported in the specialty literature; from this point of view, the present study is new and original and is also trying to point out that even with GIST, such analysis and prognosis is as valuable as in any other malignant diseases.
