Molecular Markers in Melanoma Progression: A Study on the Expression of miRNA Gene Subtypes in Tumoral vs. Benign Nevi.

This study investigates the differential expression of miRNA gene subtypes in tumoral versus benign nevi in individuals with melanoma, aiming to identify clinically significant correlations that could serve as reliable markers for assessing tumor stage and progression. Conducted between 2019 and 2022, this descriptive, quantitative observational research analyzed 90 formalin-fixed paraffin-embedded (FFPE) samples from the Pius Brinzeu County Emergency Clinical Hospital, Timisoara, including 45 samples of advanced-stage melanoma and 45 samples of pigmented nevi. miRNA purification and analysis were performed using the miRNeasy Kit and the Human Cancer PathwayFinder miScript miRNA PCR Array, with statistical analysis (including logistic regression) to determine associations with cancer staging, such as high Breslow index risk, number of mitoses, and vascular invasion. After the analysis and comparison of 180 miRNA gene subtypes, we selected 10 of the most upregulated and 10 most downregulated genes. The results revealed that hsa-miR-133b, hsa-miR-335-5p, hsa-miR-200a-3p, and hsa-miR-885-5p were significantly upregulated in melanoma samples, with fold changes ranging from 1.09 to 1.12. Conversely, hsa-miR-451a and hsa-miR-29b-3p showed notable downregulation in melanoma, with fold changes of 0.90 and 0.92, respectively. Additionally, logistic regression analysis identified hsa-miR-29b-3p (OR = 2.51) and hsa-miR-200a-3p (OR = 2.10) as significantly associated with an increased risk of a high Breslow index, while hsa-miR-127-3p and hsa-miR-451a were associated with a reduced risk. Conclusively, this study underscores the significant alterations in miRNA expression in melanoma compared to benign nevi and highlights the potential of specific miRNAs as biomarkers for melanoma progression. The identification of miRNAs with significant associations to melanoma characteristics suggests their utility in developing non-invasive, cost-effective diagnostic tools and in guiding therapeutic decisions, potentially improving patient outcomes in melanoma management.

Bacterial Species Involved in Venous Leg Ulcer Infections and Their Sensitivity to Antibiotherapy-An Alarm Signal Regarding the Seriousness of Chronic Venous Insufficiency C6 Stage and Its Need for Prompt Treatment.

BACKGROUND: Venous leg ulcers (VLUs) are a common chronic wound condition susceptible to infection by various bacterial species. Understanding bacterial presence and antibiotic sensitivity is crucial for effective treatment. Methodsː Medical records of 60 patients diagnosed with the C6 chronic venous insufficiency stage were analyzed retrospectively. The patients were divided into an active recurrent VLU group (33 cases) and a first-onset active VLU group (27 cases). Bacterial identification, antibiotic sensitivity, and laboratory markers were assessed. Resultsː Pseudomonas aeruginosa was the most prevalent bacterial species in both the study (72.72%) and control (37.03%) groups, along with other common bacteria such as Proteus mirabilis, Enterococcus sp., Staphylococcus aureus, Acinetobacter baumannii, Klebsiella spp., and Escherichia coli. Furthermore, uncommon bacteria, including Providencia rettgeri, Group B Streptococcus, and Salmonella Paratyphi B, and a fungal infection with Candida albicans, were identified only in the study group, while Morganella morganii was found exclusively in the control group. Pseudomonas aeruginosa showed significant sensitivity to several antibiotics, particularly Amikacin and Meropenem. Nonspecific laboratory markers, such as CRP, fibrinogen, ESR, WBC, CK, neutrophils, and lymphocytes, revealed statistically significant differences between groups, indicating their potential as biomarkers for monitoring recurrent VLUs. Conclusionsː These results highlight the need for comprehensive diagnostic approaches to effectively manage VLU infections and improve patient outcomes. Further research is warranted to explore factors influencing the presence of uncommon bacteria and to develop targeted interventions for VLU management.

UVA/UVB Irradiation Exerts a Distinct Phototoxic Effect on Human Keratinocytes Compared to Human Malignant Melanoma Cells.

Solar ultraviolet radiation (UVR) is responsible for the development of many skin diseases, including malignant melanoma (MM). This study assessed the phototoxic effects of UVA, and UVB radiations on healthy and pathologic skin cells by evaluating the behavior of human keratinocytes (HaCaT) and MM cells (A375) at 24 h post-irradiation. The main results showed that UVA 10 J/cm2 exerted no cytotoxicity on HaCaT and A375 cells, while UVB 0.5 J/cm2 significantly reduced cell viability and confluence, induced cell shrinkage and rounding, generated nuclear and F-actin condensation, and induced apoptosis by modulating the expressions of Bax and Bcl-2. The association of UVA 10 J/cm2 with UVB 0.5 J/cm2 (UVA/UVB) induced the highest cytotoxicity in both cell lines (viability < 40%). However, the morphological changes were different-HaCaT cells showed signs of necrosis, while in A375 nuclear polarization and expulsion from the cells were observed, features that indicate enucleation. By unraveling the impact of different UVR treatments on the behavior of normal and cancer skin cells and describing enucleation as a novel process involved in the cytotoxicity of UVA/UVB irradiation, these findings bridge the gap between the current and the future status of research in the field.

The Impact of SARS-CoV-2 Pandemic on Patients with Malignant Melanoma at a Romanian Academic Center: A Four-Year Retrospective Analysis.

Considering cancer patients may be at an increased risk of severe COVID-19 disease, their oncologic treatment cannot be delayed without risking their oncologic outcomes. Considering this, a comprehensive evaluation is required for the management of malignant diseases such as melanoma. The current study aimed to assess the impact of the COVID-19 pandemic on the delivery of cancer care services for patients diagnosed with malignant melanoma in Romania; to document the difference in patients' addressability and melanoma staging between the pandemic and pre-pandemic periods; as well as to determine the risk factors responsible for disease progression during the pandemic. We developed a retrospective analysis using a monocentric hospital database to compare the final 24 months of the pre-pandemic era to the first 24 months of the COVID-19 pandemic. All outpatients and inpatients with a diagnosis of malignant melanoma were screened during the study period and included in the analysis if matching the inclusion criteria. A total of 301 patients were included in the study, with 163 cases identified in the 24 months before the COVID-19 pandemic and 138 patients during the first 24 months of the pandemic. It was observed during the first two lockdown periods from March to May 2020, and, respectively, from October to December 2020, that significantly fewer patients with malignant melanoma presented for specialized medical care, while there was a statistically significantly lower proportion of outpatients due to COVID-19 restrictions (18.1% vs. 42.9%). The average Breslow depth was 1.1 mm before the pandemic, compared with 1.8 mm during the pandemic (p-value < 0.001). Third-stage patients were the most prevalent during both study periods, although with a statistically significant difference during the pandemic, with an increase from 90 (55.2%) patients to 94 (68.1%) (p-value < 0.001). The significant risk factors for disease progression were advanced AJCC stage (HR = 3.48), high Breslow index (HR = 3.19), postponed treatment (HR = 2.46), missed appointments (HR = 2.31), anemia at presentation (HR = 1.60), and patient's age (HR = 1.57). After the pandemic limitations are brought to an end, a broad skin-cancer-screening campaign is warranted to detect the missed cases during COVID-19.

The Epidemiology of Malignant Melanoma during the First Two Years of the COVID-19 Pandemic: A Systematic Review.

It is hypothesized that the COVID-19 pandemic had a major impact on the epidemiology of malignant melanoma owing to diminished screening, diagnostic, and treatment capacities, resulting in a more advanced stage at initial presentation. The goal of this study is to undertake a systematic analysis of all epidemiological and clinical data on the trends and patient outcomes with malignant melanoma during the ongoing pandemic. Records were identified from PubMed, Cochrane, and Web of Science, selecting a total of 39 articles, narrative reviews, and editorial letters, following the PRISMA guidelines. The vast majority of the studies were published in Europe (28/39), and North America (7/39). A total of 99,860 patients were analyzed during 2020 and 2021 of the COVID-19 pandemic, and it was observed that malignant melanoma TNM staging increased significantly compared to the pre-pandemic period. Before the pandemic, 25.88% of patients had TNM stage II or above, compared to 36.25% during 2020-2021. During the COVID-19 pandemic, the malignant melanoma Breslow depth index grew from 1.59 mm before 2020 to 1.86 mm in 2020 and 2021. Patients decreased by 19.58% in 2020 and 2021 compared to pre-pandemic numbers. The patient-loss ratio indicated lower screening activity and patient addressability to dermatology and plastic surgery departments with skin cancer concerns during the COVID-19 pandemic. This systematic study shows that the identification and management of malignant melanoma during the COVID-19 pandemic faced major challenges which should alert medical systems to the high number of patients with advanced disease stages who may need emergency treatment and become incurable.

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.

Oleogel Formulations for the Topical Delivery of Betulin and Lupeol in Skin Injuries-Preparation, Physicochemical Characterization, and Pharmaco-Toxicological Evaluation.

The skin integrity is essential due to its pivotal role as a biological barrier against external noxious factors. Pentacyclic triterpenes stand as valuable plant-derived natural compounds in the treatment of skin injuries due to their anti-inflammatory, antioxidant, antimicrobial, and healing properties. Consequently, the primary aim of the current investigation was the development as well as the physicochemical and pharmaco-toxicological characterization of betulin- and lupeol-based oleogels (Bet OG and Lup OG) for topical application in skin injuries. The results revealed suitable pH as well as organoleptic, rheological, and textural properties. The penetration and permeation of Bet and Lup oleogels through porcine ear skin as well as the retention of both oleogels in the skin were demonstrated through ex vivo studies. In vitro, Bet OG and Lup OG showed good biocompatibility on HaCaT human immortalized cells. Moreover, Bet OG exerted a potent wound-healing property by stimulating the migration of the HaCaT cells. The in ovo results demonstrated the non-irritative potential of the developed formulations. Additionally, the undertaken in vivo investigation indicated a positive effect of oleogels treatment on skin parameters by increasing skin hydration and decreasing erythema. In conclusion, oleogel formulations are ideal for the local delivery of betulin and lupeol in skin disorders.

Melissa officinalis L. Aqueous Extract Exerts Antioxidant and Antiangiogenic Effects and Improves Physiological Skin Parameters.

Melissa officinalis (MO) is a medicinal plant well-known for its multiple pharmacological effects, including anti-inflammatory, anticancer and beneficial effects on skin recovery. In this context, the present study was aimed to investigate the in vitro and in vivo safety profile of an MO aqueous extract by assessing cell viability on normal (HaCaT-human keratinocytes) and tumor (A375-human melanoma) cells and its impact on physiological skin parameters by a non-invasive method. In addition, the antioxidant activity and the antiangiogenic potential of the extract were verified. A selective cytotoxic effect was noted in A375 cells, while no toxicity was noticed in healthy cells. The MO aqueous extract safety profile after topical application was investigated on SKH-1 mice, and an enhanced skin hydration and decreased erythema and transepidermal water loss levels were observed. The in ovo CAM assay, performed to investigate the potential modulating effect on the angiogenesis process and the blood vessels impact, indicated that at concentrations of 100 and 500 µg/mL, MO aqueous extract induced a reduction of thin capillaries. No signs of vascular toxicity were recorded at concentrations as high as 1000 µg/mL. The aqueous extract of MO leaves can be considered a promising candidate for skin disorders with impaired physiological skin parameters.

Surgical management of dissecting cellulitis of the scalp using free latissimus dorsi flap and meshed split-thickness skin graft: A case report.

INTRODUCTION: Dissecting cellulitis of the scalp, or Hoffman disease, is described as an extremely rare condition. Clinically, it is represented by recurrent painful nodules, purulent drainage, interconnected sinus tracts and keloid formation, leading to scaring and cicatricial alopecia. Without a precise diagnosis and an adequate treatment, the repercussions consist of severe infectious complications along with psychological negative effects and serious aesthetic alterations. There is no standard treatment. In refractory cases, surgical management is reported. PATIENT CONCERNS: We report a case of a 65-year-old Caucasian male patient, with a 5-year history of Hoffman disease, who presented with multiple abscesses and sinus tracts of the scalp and patches of alopecia. The lesions were non-responsive to medical treatment. DIAGNOSIS: The diagnosis of DCS has been established on the basis of the clinical appearance and has been confirmed histopathologically. INTERVENTIONS: The patient underwent wide excision of the scalp, followed by reconstruction using free latissimus dorsi flap and covered by meshed split-thickness skin graft. OUTCOMES: Eighteen-month follow-up revealed complete remission of symptoms and lesions along with satisfactory cosmetic result. CONCLUSION: The scope of this case report is to raise awareness of the following aspects: Hoffman disease has an extremely low occurrence rate, a difficult differential diagnosis and no standard therapeutical strategy. It also highlights the effectiveness of scalpectomy and free latissimus dorsi flap covered by meshed split-thickness skin graft in treating a very advanced stage of the disease together with providing a natural contouring of the scalp. Ultimately, it discusses the other treatment alternatives.

The Moderating Role of Personal Resources Between Demands and Ill-Being of Romanian Healthcare Professionals in the COVID-19 Pandemic.

Background and Objectives: The illness caused by the new coronavirus (COVID-19) triggered considerable mental consequences for the medical staff. Our aim was to research whether frontline healthcare workers' positive psychological state-PsyCap-impacts the relationship between anxiety/depression and burnout/mental health complaints. Material and Methods: One hundred twenty-six medical professionals working on the frontline at the Intensive Care Unit and Emergency Department in Romania took validated surveys between March and April 2020. All information was collected online after accessing a link that was received in an email message. The inclusion criteria concerned the categories of healthcare professionals who came into direct contact with patients during the COVID-19 global epidemic through the performed medical act, as well as time spent in the medical field of ICU an EM, namely at least 1 year in the department. We excluded from the research other categories of employees and auxiliary staff, as well as healthcare workers with <1-year experience in the medical field. The moderating role of personal resources (PsyCap) between demands (such as anxiety and depression) and ill-being (burnout and mental health complaints) of healthcare professionals were tested via hierarchical multiple regressions. Results: We tested the moderating role of PsyCap on the relation between anxiety and ill-being. The results indicated that high anxiety predicts lower emotional exhaustion and a low level of mental health complaints about Romanian healthcare professionals when PsyCap is high. The moderating role of PsyCap on the relation between depression and ill-being was tested in the second hypothesis. The results indicated that high depression predicts lower inefficacy and a low level of mental health complaints about Romanian healthcare professionals when PsyCap is increased. Conclusions: PsyCap is a crucial variable that may decrease the impact of anxiety and depression on psychological outcomes such as emotional exhaustion, inefficacy, and psychological problems among Romanian medical professionals working on the frontline during the COVID-19 global epidemic. Thus, psychological interventions that help medical staff gain personal resources are appropriate in the context of the COVID-19 pandemic.

Infodemia: Another Enemy for Romanian Frontline Healthcare Workers to Fight during the COVID-19 Outbreak.

Background and Objectives: The population has been overwhelmed with false information related to the Coronavirus disease (COVID-19) crisis, spreading rapidly through social media and other channels. We aimed to investigate if frontline healthcare workers affected by infodemia show different psychological consequences than frontline clinicians who do not declare to be affected by false news related to the COVID-19 pandemic. Materials and Methods: One hundred twenty-six frontline healthcare workers from the Intensive Care Unit (ICU) and Emergency Departments in Romania completed a survey to assess stress, depression, anxiety, and sleep disorders, between March and April 2020. We split the sample of frontline healthcare workers into two groups based on the self-evaluated criteria: if they were or were not affected by infodemia in their activity. Results: Considering limitations such as the cross-sectional design, the lack of causality relationship, and the sample size, the results show that, the frontline medical workers who declared to be affected by false news were significantly more stressed, felt more anxiety, and suffered more from insomnia than healthcare workers who are not affected by false information related to pandemic time. Conclusions: The infodemia has significant psychological consequences such as stress, anxiety, and insomnia on already overwhelmed doctors and nurses in the outbreak of the COVID-19 crisis. These findings suggest that medical misinformation's psychological implications must be considered when different interventions regarding frontline healthcare workers during the COVID-19 pandemic are implemented.

The Mediating Role of Insomnia and Exhaustion in the Relationship between Secondary Traumatic Stress and Mental Health Complaints among Frontline Medical Staff during the COVID-19 Pandemic.

The outbreak of coronavirus disease (COVID-19) brought significant psychological implications for healthcare professionals. We aimed to investigate the serial mediation effect of insomnia and exhaustion in the relationship between secondary traumatic stress (STS) and mental health complaints among the frontline healthcare professionals during the COVID-19 pandemic. In this cross-sectional study, 126 frontline healthcare workers from Romania completed validated surveys between March and April 2020. PROCESS macros were used to test the proposed hypotheses of the three-path mediation model. We computed the models for insomnia as the first mediator (M1) and exhaustion (M2) as our second mediator. STS was significantly related to insomnia. Insomnia was significantly related to exhaustion, and STS was positively related to exhaustion. In the third model, exhaustion was strongly and positively related to mental health complaints. The total indirect effect was positive, and the sequential indirect impact of STS on mental health complaints via both mediators in series (insomnia and exhaustion) was significant. Secondary traumatic stress had a positive direct effect on mental health complaints. In our limited sample, the results show that frontline medical staff during the COVID-19 outbreak have high STS, which are related to mental health complaints through insomnia and exhaustion.

Comparison of early pregnancy serum concentration of neopterin, neopterin/creatinine ratio, C-reactive protein, and chitotriosidase, in pregnant women with birth at term and spontaneous preterm birth.

Inflammatory mechanisms are involved in achieving a normal pregnancy and in the development of certain pregnancy complications. These changes are more intense in pregnant women that suffer of pregnancy complications, such as spontaneous preterm birth (SPB). This study compared the course of inflammatory markers (IM) [neopterin (Neo), neopterin/creatinine ratio (Neo/Cre), C-reactive protein (CRP), and chitotriosidase (Chito)] serum concentration in the early pregnancy of women with birth at term (BT) and preterm birth (PB). IM concentration was measured in 90 sera sampled from 45 pregnancies with BT and 30 sera from 15 pregnancies with PB. Two sera were sampled from each pregnant woman: one in the first trimester and another one in the second trimester. Early pregnancy IM concentration showed a direct correlation with gestational age: Neo (rho=0.262, P=0.004), Neo/Cre (rho=0.372, P<0.001), CRP (rho=0.187, P=0.041), and Chito (rho=0.039, P=0.66). The correlation was present in both categories of patients with BT and PB. Patients with PB before 34 week of pregnancy (wp) and 32 wp showed higher Neo and Neo/Cre concentration than BT patients. A significant association was found between the risk of PB before 34 wp, PB before 32 wp, and Neo concentration (PB <34 wp: odds ratio (OR) =5.13, P=0.035) (PB <32 wp: OR=8.2, P=0.020) and, respectively, Neo/Cre concentration (PB <34 wp: OR=5.29, P=0.015) (PB <32 wp: OR=9.25, P=0.006). No association between CRP or Chito and PB age was found. IM concentration correlates with the gestational age at the time of blood sampling. Increased Neo and Neo/Cre concentration are associated with PB. Further studies are needed to evaluate the usefulness of these markers in clinical practice.

The influence of cognitive schemas on the mixed anxiety-depressive symptoms of breast cancer patients.

BACKGROUND: The surgical treatment of breast cancer involves various psychological consequences, which differ according to individual characteristics. Our study aimed to identify the role that cognitive schemas had in triggering anxiety and depressive symptoms in patients diagnosed with breast cancer that underwent oncological and plastic surgery treatment. METHODS: 64 female patients, diagnosed with breast cancer from an Oncology and Plastic Surgery Hospital, were selected to participate in this study between March-June 2018. They were divided into two groups: I. 28 patients who underwent mastectomy surgery; II. 36 patients, who required mastectomy and, subsequently, also chose to undergo breast reconstruction surgery. For the purposes of evaluating a possible change in mental health status, we employed two assessment scales: the Young Cognitive Schema Questionnaire - Short Form 3 (YSQ-S3) and the Romanian version of the Depression Anxiety Stress Scale - 21 (DASS-21R). RESULTS: Participants who underwent mastectomy and subsequent breast reconstruction surgery employed cognitive schemas that did not generate symptoms of depression or anxiety. In contrast, the cognitive schemas found in women who refused reconstructive breast surgery were significantly correlated with the presence of anxiety-depressive symptoms. The cognitive schema domain of 'disconnection and rejection' correlated uncertainly with the presence of anxiety-depressive symptoms for the group with breast reconstruction (Spearman's ρ = 0.091, p = 0.644), while for the other group the correlation was moderate-strong (Spearman's ρ = 0.647, p <  0.01). Negative emotional schemas were significantly correlated with the presence of anxiety-depressive symptoms (Spearman's ρ = 0.598, p <  0.01) in the group of participants without reconstructive surgery. CONCLUSION: A correct identification of dysfunctional cognitive schemas and coping mechanisms at the commencement of the combined treatment in breast cancer patients could serve as an indicator for the evolution of their mental health, therefore assisting professionals in establishing the most suitable psychological, psychotherapeutic and psychiatric intervention plan.

Assessment of Metabolic and Nutritional Imbalance in Mechanically Ventilated Multiple Trauma Patients: From Molecular to Clinical Outcomes.

The critically ill polytrauma patient is characterized by a series of metabolic changes induced by inflammation, oxidative stress, sepsis, and primary trauma, as well as associated secondary injuries associated. Metabolic and nutritional dysfunction in the critically ill patient is a complex series of imbalances of biochemical and genetic pathways, as well as the interconnection between them. Therefore, the equation changes in comparison to other critical patients or to healthy individuals, in which cases, mathematical equations can be successfully used to predict the energy requirements. Recent studies have shown that indirect calorimetry is one of the most accurate methods for determining the energy requirements in intubated and mechanically ventilated patients. Current research is oriented towards an individualized therapy depending on the energy consumption (kcal/day) of each patient that also takes into account the clinical dynamics. By using indirect calorimetry, one can measure, in real time, both oxygen consumption and carbon dioxide production. Energy requirements (kcal/day) and the respiratory quotient (RQ) can be determined in real time by integrating these dynamic parameters into electronic algorithms. In this manner, nutritional therapy becomes personalized and caters to the patients' individual needs, helping patients receive the energy substrates they need at each clinically specific time of treatment.

Thrombospondin-1 Serum Levels In Hypertensive Patients With Endothelial Dysfunction After One Year Of Treatment With Perindopril.

BACKGROUND: Thrombospondin-1 (TSP-1) is a matricellular functional protein of the extracellular matrix. As it is not constitutively present extracellularly, its secretion is enhanced in several situations, namely injury, chronic pathology, tissue remodeling, angiogenesis, and aging. Over the last decade, TSP-1 has been reported to be involved in complex and opposing biological effects on vasculature in the context of NO signaling. Several studies have reported high patient TSP-1 plasma levels, indicating that the protein can potentially serve as a prognostic marker for pulmonary arterial hypertension. MATERIALS AND METHODS: Here, we aimed to quantify TSP-1 serum levels in hypertensive patients with endothelial dysfunction before and after one year of treatment with Perindopril (an antihypertensive drug with vasoprotective properties). RESULTS: After one year of treatment, TSP-1 levels increased in hypertensive patients compared to baseline (T0: 8061.9 ± 3684.80 vs T1: 15380±5887 ng/mL, p<0.001) and compared to non-hypertensive controls (9221.03 ± 6510.21 ng/mL). In contrast, pentraxin-3 plasma levels were decreased after one year of Perindopril treatment in both hypertensive (T0: 0.91 ± 0.51 vs T1: 0.50 ± 0.24 ng/mL, p<0.001) and control group (1.36 ±1.5 ng/mL) patients, although flow-mediated vasodilation and intima-media thickness assessment parameters were not significantly changed. Systolic and diastolic blood pressure values as well as levels of fibrinogen, high-sensitivity C-reactive protein, triglycerides, and alanine aminotransferase were found to be significantly lower after one year of treatment with Perindopril. High levels of TSP-1 strongly correlated with platelet count (positive), lymphocytes (positive), red cell distribution width-CV (positive), systolic blood pressure (negative), and mean corpuscular hemoglobin (negative) after one year of treatment. Blood urea nitrogen was found to be a protective factor for TSP-1, while glucose and heart rate were found to be risk factors prior to and after treatment.

Romanian Wormwood (Artemisia absinthium L.): Physicochemical and Nutraceutical Screening.

Artemisia species are used worldwide for their antioxidant, antimicrobial and anti-inflammatory properties. This research was designed to investigate the phytochemical profile of two ethanolic extracts obtained from leaves and stems of A. absinthium L. as well as the biological potential (antioxidant activity, cytotoxic, anti-migratory and anti-inflammatory properties). Both plant materials showed quite similar thermogravimetric, FT-IR phenolic profile (high chlorogenic acid) with mild antioxidant capacity [ascorbic acid (0.02-0.1) > leaves (0.1-2.0) > stem (0.1-2.0)]. Alcoholic extracts from these plant materials showed a cytotoxic effect against A375 (melanoma) and MCF7 (breast adenocarcinoma) and affected less the non-malignant HaCaT cells (human keratinocytes) at 72 h post-stimulation and this same trend was observed in the anti-migratory (A375, MCF7 > HaCat) assay. Lastly, extracts ameliorated the pro-inflammatory effect of TPA (12-o-tetradecanoylphorbol-13-acetate) in mice ears, characterized by a diffuse neutrophil distribution with no exocytosis or micro-abscesses.

Adipose Tissue Graft Improves Early but not Late Stages of Nerve Regeneration.

AIM: The aim of the study was to assess the effect of autologous fat graft on nerve regeneration by means of immunohistochemistry. MATERIALS AND METHODS: The rat sciatic nerve was used; complete transection followed by primary neurorrhaphy was performed on both hind legs, on the left side a processed fat graft was applied, surrounding the nerve. Nerve biopsies were collected and immunohistochemical procedures were performed for glial fibrillary acidic protein (GFAP) and for neurofilament-associated protein(NFAP). RESULTS: At 4 weeks, GFAP-positive cells were observed in the connective tissue formed between the two nerve endings on the left side only. At 10 weeks, GFAP-positive structures were present and exhibited a tendency to become linear on both sides, with an increased density on the left. NFAP-positive expression was present in the left treated limb with a disorganized pattern. CONCLUSION: Adipose tissue led to the stimulation of GFAP-positive Schwann cells, which could have a positive impact on nerve regeneration in the clinical setting.

The Use of Exosomes as Biomarkers for Evaluating and Monitoring Critically Ill Polytrauma Patients with Sepsis.

Regarding genetic biomarkers for early assessment and monitoring the clinical course in polytrauma patients with sepsis, in recent years a remarkable evolution has been highlighted. One of the main representatives is the exosome miRNAs. In this paper, we would like to present in more details the various methods of using exosome miRNAs as a biomarker for monitoring polytrauma patients with sepsis, as well as establishing a belated outcome by aggregating the entire clinical aspects. The use of exosome miRNAs for late evaluating and monitoring the clinical evolution of polytrauma patients can bring significant improvements in current clinical practice through the optimization and modulation of intensive care according to the needs of each patient individually.

The Use of Redox Expression and Associated Molecular Damage to Evaluate the Inflammatory Response in Critically Ill Patient with Severe Burn.

The patient with severe burns always represents a challenge for the trauma team due to the severe biochemical and physiopathological disorders. Although there are many resuscitation protocols of severe burn patient, systemic inflammatory response, oxidative stress, decreased immune response, infections, and multiple organ dysfunction syndromes are still secondary complications of trauma, present at maximum intensity in this type of patients. Currently there are numerous studies regarding the evaluation, monitoring, and minimizing the side effects induced by free radicals through antioxidant therapy. In this study, we want to introduce biochemical and physiological aspects of oxidative stress in patients with severe burns and to summarize the biomarkers used presently in the intensive care units. Systemic inflammations and infections are according to the literature the most important causes of death in these type of patients, being directly involved in multiple organ dysfunction syndrome and death.
