Recent Updates Regarding the Antiproliferative Activity of Galium verum Extracts on A375 Human Malignant Melanoma Cell Line.

The biological activity of Galium verum herba was exerted on various tumor cell lines with incredible results, but their potential effect on malignant melanoma has not been established yet. Therefore, the current study was structured in two directions: (i) the investigation of the phytochemical profile of diethyl ether (GvDEE) and butanol (GvBuOH) extracts of G. verum L. and (ii) the evaluation of their biological profile on A375 human malignant melanoma cell line. The GvDEE extract showed an FT-IR profile different from the butanol one, with high antioxidant capacity (EC50 of GvDEE = 0.12 ± 0.03 mg/mL > EC50 of GvBuOH = 0.18 ± 0.05 mg/mL). The GvDEE extract also showed antimicrobial potential, especially against Gram-positive bacteria strains, compared to the butanol extract, which has no antimicrobial activity against any bacterial strain tested. The results regarding the antitumor potential showed that both extracts decreased A375 cell viability largely (69% at a dose of 55 µg/mL of the GvDEE extract). Moreover, both extracts induce nuclear fragmentation by forming apoptotic bodies and slight chromatin condensation, which is more intense for GvDEE. Considering the results, one can state that the Galium verum herba possesses antitumor effects on the A375 human malignant melanoma cell line, a promising phytocompound for the antitumor approach to skin cancer.

Cystic Echinococcosis in Hospitalized Adult Patients from Western Romania: 2007-2022.

Cystic echinococcosis (CE) is a neglected parasitic disease caused by the tapeworm Echinococcus granulosus. The aim of this study was to assess the epidemiological features of human cystic echinococcosis in patients from Western Romania. We retrospectively investigated the medical records of patients hospitalized with CE between 1 January 2007 and 1 September 2022. A total of 366 patients (range 18-90 years) were recorded. The number of hospitalized individuals was higher in patients aged 50-59 years (83/366, 22.7%), in females (194/366, 53%), and in residents of rural areas (225/366, 61.5%). The liver was the most common localization of the cysts (302/366, 82.5%). Ninety-eight patients (26.8%) presented complications, including biliary fistula, allergies, and infection of the cyst. Patients with complications had a longer mean hospital stay (15.7 ± 8.3 days) compared to patients without complications (11.5 ± 7.3 days) (p < 0.001). The results of this study revealed that patients diagnosed with CE required hospitalization and extended medical care, indicating that this zoonotic disease remains a significant public health problem in Western Romania. Public health authorities should enhance CE surveillance by implementing control programs and mandatory notification of new cases.

A rare encounter with two cases of Budd­Chiari syndrome in the Emergency Department: A case report.

Budd-Chiari syndrome (BCS) is a rare disorder clinically characterized by abdominal pain, hepatomegaly and ascites. The condition is often related to thrombosis of the hepatic veins or the terminal portion of the inferior vena cava. A myeloproliferative disorder is the most identified underlying prothrombotic risk factor, although almost one-half of affected patients are now recognized as having multiple underlying prothrombotic risk factors. Doppler ultrasound may be enough to confirm the diagnosis of BCS; however, computed tomography or magnetic resonance imaging is often employed. Anticoagulant therapy is the cornerstone of BCS treatment, but most patients also need additional treatment strategies. Most patients with BCS are now treated by endovascular intervention, which has improved survival rate in those afflicted by this disease. The long-term course of the disease can be complicated by progression or recurrence of the underlying myeloproliferative disorder. The present study reports the cases of two patients with BCS with the aim of alerting healthcare workers in Emergency Departments of this less common diagnosis in patients presenting with frequent complaints of abdominal pain.

True Brachial Artery Aneurysm in Patients with Previous Arterio-Venous Fistula Ligation and Immunosuppressant Therapy for Renal Transplantation: Case Report and Literature Review.

BACKGROUND/OBJECTIVE: Brachial artery aneurysm (BAA) is a serious complication in patients with previous arterio-venous fistula (AVF), renal transplantation (RT), and immunosuppressive regimens. Until now, there has been no standard of care for these patients, especially for patients undergoing chronic dialysis and immunosuppressive treatment. The aim of this study was to investigate data from the literature regarding these patients and to suggest recommendations for the best approach to their treatment. METHODS: A review of the literature was performed by searching the PubMed database in the English language. The review was accompanied by two case reports. A total of 24 articles with different variables-demographics, renal transplantation, aneurysm size, and type of surgery-were subjected to the review. In addition, two cases are reported. CONCLUSION: This review suggests that the best treatment for these patients is open surgery, with aneurysmectomy and graft interposition. RESULTS: All patients had RT. The age of patients ranged from 26-77 yo, with a male predominance. The majority had an AVF ligated after RT. The main clinical symptoms were pain, swelling, and pulsatile mass (66%). All patients, except one, were treated through open surgery. The first option for treatment was reversed saphenous vein graft interposition (36%), followed by ePTFE graft (16%).

Eugenol Induces Apoptosis in Tongue Squamous Carcinoma Cells by Mediating the Expression of Bcl-2 Family.

Head and neck squamous cell carcinoma is highly aggressive type of cancer for which the available treatment often causes patients severe side effects. Eugenol (Eug) is the major active constituent of clove essential oil and is known to possess antitumor properties. The present study aimed to assess the in vitro cytotoxicity of eugenol in SCC-4, tongue squamous carcinoma cells, and also in HGF, human gingival fibroblasts. Both cell lines were treated with five concentrations of Eug (0.1-1 mM) for 72 h. Cellular viability was assessed, followed by cellular morphological evaluation and by staining of the nuclei and cytoskeleton. RT-PCR was conducted in order to find the effect eugenol had on the expression on Bad, Bax, and Bcl-2 genes. Eugenol induced a dose-dependent decrease in viability in both cell lines, with the SCC-4 cells being significantly more affected. HGF cells detached from the plate at the highest concentrations used, while SCC-4 cells changed their morphology in a dose-dependent manner, with rounding, floating cells, and confluency loss being observed. Apoptotic-like signs such as chromatin and actin filaments condensation were clearly seen in SCC-4 cells, while RT-PCR revealed a significantly increased expression of pro-apoptotic genes Bax and Bad. Therefore, eugenol exerts its cytotoxic effect in tongue squamous cell carcinoma through inducing apoptosis.

The utility of indirect imagistic signs in the diagnosis of anterior cruciate ligament ruptures.

We conducted a retrospective study, between 2013 and 2018. The study was conducted by analyzing the comparative imaging of two groups of patients. The two groups comprise 42 patients, 14 women and 28 men aged between 17 and 70 years old, to whom objective variables of statistical relevance were tracked. The results of this study show that there is a significant correlation between an angle value of less than 45° and the rupture of the anterior crossed ligament.

The Use of Circulating miRNAs as Biomarkers for Oxidative Stress in Critically Ill Polytrauma Patients.

BACKGROUND: The diversity of primary and secondary traumatic injuries specific for the critically ill polytrauma patient is complicating the therapeutic management in the absence of a strict assessment of the biological changes. Inflammation, redox imbalance, and immunosuppression can be quantified by various biochemical parameters; however, they do not fully respond to the current requirements. Another phenomenon responsible for worsening the clinical status and for the development of complications in such patients is oxidative stress. Its aggressiveness combined with biochemical and physiological imbalances leads to increased morbidity and mortality. To minimize the effects induced by free radicals, various substances are administered with high antioxidant capacity. However, the dosage optimization for each patient is difficult without strict monitoring of oxidative stress. In this paper we will summarize and present the pathophysiology of oxidative stress, as well as the specificity of miRNAs for a series of molecular changes at the cellular level. METHODS: For this study the available literature on specific databases such as PubMed, Embase and Scopus was thoroughly analyzed. Each article has been carefully reviewed, extracting useful information for this study. The keywords used to select the relevant articles were "oxidative stress", "antioxidant therapy", "microRNAs biomarkers", and "critically ill patients". RESULTS: For this study, 121 scientific articles relevant to our topic were analyzed. Currently, quantification of oxidative stress is achieved through indirect correlations with plasma levels of specific biomarkers. For a more specific evaluation of the redox status, numerous studies were conducted on the use of circulating miRNAs as biomarkers in this regard. CONCLUSIONS: Introducing miRNAs can revolutionize both monitoring and therapy modulation in these patients, adapting to the organic damage.
