RESUMEN
A multicenter, observational, cross-sectional study was conducted to assess the sexual function of male survivors of hematological malignancy treated by autologous hematopoietic stem cell transplantation (AHSCT) and to compare it with that of healthy male controls. By convenience sampling, 71 sexually active male survivors of hematological malignancy who underwent AHSCT were recruited, as well as 74 healthy men. A questionnaire with demographic and clinical data and the International Index of Erectile Function (IIEF) were completed. Survivors had a median age of 47 years, a median time since transplant of 3 years, and 46.5% had Hodgkin lymphoma. Based on the IIEF, they had a high level of sexual function, with best functioning domain "erection" and worst "overall satisfaction". Healthy men had statistically significantly higher scores in all domains of the IIEF, except for "orgasm" (p = 0.205). There was a statistically significant association between sexual function and age (p < 0.0005), years since transplantation (p = 0.006), functional status (p < 0.0005), having children (p < 0.0005), relationship status (p = 0.001), education (p < 0.0005), diagnosis (p < 0.0005) and disease relapse (p = 0.017). Multivariate analysis showed that only age was a strong prognostic factor of sexual function (p < 0.0005). After age was excluded from the model, because of the strong effect it had on the dependent variable, functional status (p = 0.015), education (p = 0.002) and diagnosis (p = 0.001) had a statistically significant association with sexual function. These findings indicate the importance of sexual function for survivors' well-being and the need for implementation of integrated care plans for survivors of hematological malignancy.

HELLP (Hemolysis, Elevated Liver enzymes and Low Platelets) syndrome is a life-threatening complication of pregnancy, which is often secondary to preeclampsia. To date, there is no biomarker in clinical use for the early stratification of women with preeclampsia who are under increased risk of HELLP syndrome. Herein, we show that the levels of circulating developmental endothelial locus-1 (DEL-1), which is an extracellular immunomodulatory protein, are decreased in patients with HELLP syndrome compared to preeclampsia. DEL-1 levels are also negatively correlated with the circulating levels of kidney injury molecule-1 (KIM-1), which is a biomarker for disorders associated with kidney damage. Receiver-operating characteristic curve analysis for DEL-1 levels and the DEL-1 to KIM-1 ratio demonstrates that these values could be used as a potential biomarker that distinguishes patients with HELLP syndrome and preeclampsia. Finally, we show that placental endothelial cells are a source for DEL-1, and that the expression of this protein in placenta from patients with HELLP syndrome is minimal. Taken together, this study shows that DEL-1 is downregulated in HELLP syndrome both in the circulation and at the affected placental tissue, suggesting a potential role for this protein as a biomarker, which must be further evaluated.

Previous studies have shown that COVID-19 leads to thrombotic complications, which have been associated with high morbidity and mortality rates. Neutrophils are the largest population of white blood cells and play a pivotal role in innate immunity. During an infection, neutrophils migrate from circulation to the infection site, contributing to killing pathogens. This mechanism is regulated by chemokines such as IL-8. Moreover, it was shown that neutrophils play an important role in thromboinflammation. Through a diverse repertoire of mechanisms, neutrophils, apart from directly killing pathogens, are able to activate the formation of thrombi. In COVID-19 patients, neutrophil activation promotes neutrophil extracellular trap (NET) formation, platelet aggregation, and cell damage. Furthermore, neutrophils participate in the pathogenesis of endothelitis. Overall, this review summarizes recent progress in research on the pathogenesis of COVID-19, highlighting the role of the prothrombotic action of neutrophils in NET formation.

BACKGROUND: The SARS-CoV2 pandemic obligated most of the European countries to implement strict measures and lockdowns to minimize the spread of the virus. Universities closed and on-line classes started. However, COVID-19 epidemic has significant impact on mental health of population. AIM: To assess depression level of nursing students (undergraduate and master) in Greece, Spain and Albania during COVID-19 pandemic as well as to identify possible determinants of depression level. METHODS: A multicenter cross-sectional study was conducted between April and May 2020. An on-line questionnaire was used to collect the data. The Patient Health Questionnaire-9 was used to evaluate the depression levels of nursing students. RESULTS: Seven hundred and eighty-seven nursing students participated in the study out of which 83.9% were of female gender, 92.9% single and 94.7% lived with others. One third of the nursing student population experienced mild depression, with higher depression levels noted for Spanish students (59.1%) followed by Albanian (34.5%) and Greek (21.8%) students. Multivariate linear regression analysis identified that Spanish students experienced more depression than Greek and Albanian (p < 0.001). Also, decreased age was associated with increased depression. CONCLUSION: The impact of lockdown and quarantine on nursing students mental health is clear. Provision of university based mental health interventions should be a priority.

PURPOSE: To present the impact of the financial crisis on health status and dental health in Greece and compare it to the European Union and Finland and to identify any changes in health-related expenditure focusing on pharmaceutical expenditure and generic medicines. DESIGN/METHODOLOGY/APPROACH: Databases as Scopus, Pubmed, Google Scholar, World Health Organization, Eurostat, and Elstat were used. FINDINGS: Indicators, such as mortality and life expectancy, show that there is no clear correlation between health deterioration and financial crisis while dental health has deteriorated. Out-of-pocket expenses were found to be catastrophic, and the use of generic medicines is still limited. PRACTICAL IMPLICATIONS: Proper prescribing of medicines, coverage of health care costs by the government, and cost savings from the use of generic medicines were implemented. As regards dental care, the state should focus on prevention as well as reinforcement of public dental care services. ORIGINALITY/VALUE: The break through idea is to compare the impact of the financial crisis on health indexes in Greece with the European Union and Finland, to focus on pharmaceutical expenditure, generic medicines, and dental health.

AIMS AND OBJECTIVES: To explore the gender-specific associations of smoking with convivial, negative coping and intimate drinking contexts in young adults. BACKGROUND: Alcohol and cigarettes co-use is common and to be more effective in prevention activities, we need to understand the drinking contexts that facilitate their co-occurrence. DESIGN: Descriptive cross-sectional survey in the context of the LATO study (Lifestyle & Attitudes in a Student Population) in Greece. METHODS: Of the 1,138 students who provided full data during November-December 2012, those who have smoked ≥1 cigarette/last month were defined as smokers. Based on the "Drinking Context Scale-9", we created low, moderate and high probabilities of drinking in each context and in total. Multivariate logistic regression analyses were performed. RESULTS: Participants reported higher probabilities to drink, in descending order, in the convivial (31.5%), negative coping (10.4%) and intimate (5.4%) contexts. Adjusted odds ratios for smoking were significantly higher for individuals who reported a moderate (OR = 2.15, 95% CI 1.51-3.05) to high (OR = 3.64, 95% CI 2.59-5.11) probability of drinking in any context. Moreover, female participants with high probabilities for drinking in convivial and negative coping contexts had higher odds ratios of engaging in smoking (convivial OR = 1.87, 95% CI = 1.23-2.85; coping OR = 2.66, 95% CI = 1.39-5.10) whereas this association was noticed only for convivial settings in male participants (OR = 2.88, 95% CI = 1.91-4.319). For women only, drinking in intimate contexts was protective against smoking (OR = 0.32, 95% CI = 0.10-0.98). CONCLUSIONS: Smoking is differentially related to drinking context based on gender. Prevention interventions targeting smoking and alcohol co-use in late adolescence may be more effective if employing a context and gender-specific approach. RELEVANCE TO CLINICAL PRACTICE: Nurses have a critical role in providing motivational interviewing in individuals and organise and execute health-promoting activities in larger groups for modifying their health risk behaviours. The social context should be carefully considered during assessments and prevention interventions.

BACKGROUND: Familial Mediterranean fever (FMF) is an IL-1ß-dependent autoinflammatory disease caused by mutations of Mediterranean fever (MEFV) encoding pyrin and characterized by inflammatory attacks induced by physical or psychological stress. OBJECTIVE: We investigated the underlying mechanism that links stress-induced inflammatory attacks with neutrophil activation and release of IL-1ß-bearing neutrophil extracellular traps (NETs) in patients with FMF. METHODS: RNA sequencing was performed in peripheral neutrophils from 3 patients with FMF isolated both during attacks and remission, 8 patients in remission, and 8 healthy subjects. NET formation and proteins were analyzed by using confocal immunofluorescence microscopy, immunoblotting, myeloperoxidase-DNA complex ELISA, and flow cytometry. Samples from patients with Still's disease and bacterial infections were used also. RESULTS: The stress-related protein regulated in development and DNA damage responses 1 (REDD1) is significantly overexpressed during FMF attacks. Neutrophils from patients with FMF during remission are resistant to autophagy-mediated NET release, which can be overcome through REDD1 induction. Stress-related mediators (eg, epinephrine) decrease this threshold, leading to autophagy-driven NET release, whereas the synchronous inflammatory environment of FMF attack leads to intracellular production of IL-1ß and its release through NETs. REDD1 in autolysosomes colocalizes with pyrin and nucleotide-binding domain, leucine-rich repeat/pyrin domain-containing 3. Mutated pyrin prohibits this colocalization, leading to higher IL-1ß levels on NETs. CONCLUSIONS: This study provides a link between stress and initiation of inflammatory attacks in patients with FMF. REDD1 emerges as a regulator of neutrophil function upstream to pyrin, is involved in NET release and regulation of IL-1ß, and might constitute an important piece in the IL-1ß-mediated inflammation puzzle.

Cervical cancer is strongly related to certain high-risk types of human papilloma virus infection. Breast cancer metastasis suppressor 1 (BRMS1) is a tumor suppressor gene, its expression being regulated by DNA promoter methylation in several types of cancers. This study aims to evaluate the methylation status of BRMS1 promoter in relation to high-risk types of human papilloma virus infection and the development of pre-cancerous lesions and describe the pattern of BRMS1 protein expression in normal, high-risk types of human papilloma virus-infected pre-cancerous and malignant cervical epithelium. We compared the methylation status of BRMS1 in cervical smears of 64 women with no infection by high-risk types of human papilloma virus to 70 women with proven high-risk types of human papilloma virus infection, using real-time methylation-specific polymerase chain reaction. The expression of BRMS1 protein was described by immunohistochemistry in biopsies from cervical cancer, pre-cancerous lesions, and normal cervices. Methylation of BRMS1 promoter was detected in 37.5% of women with no high-risk types of human papilloma virus infection and was less frequent in smears with high-risk types of human papilloma virus (11.4%) and in women with pathological histology (cervical intraepithelial neoplasia) (11.9%). Methylation was detected also in HeLa cervical cancer cells. Immunohistochemistry revealed nuclear BRMS1 protein staining in normal high-risk types of human papilloma virus-free cervix, in cervical intraepithelial neoplasias, and in malignant tissues, where staining was occasionally also cytoplasmic. In cancer, expression was stronger in the more differentiated cancer blasts. In conclusion, BRMS1 promoter methylation and aberrant protein expression seem to be related to high-risk types of human papilloma virus-induced carcinogenesis in uterine cervix and is worthy of further investigation.

Macrolide antibiotics have been shown to act as immunomodulatory molecules in various immune cells. However, their effect on neutrophils has not been extensively investigated. In this study, we investigated the role of macrolide antibiotics in the generation of neutrophil extracellular traps (NETs). By assessing ex vivo and in vivo NET formation, we demonstrated that clarithromycin is able to induce NET generation both in vitro and in vivo. Clarithromycin utilizes autophagy in order to form NETs, and these NETs are decorated with antimicrobial peptide LL-37. Clarithromycin-induced NETs are able to inhibit Acinetobacter baumannii growth and biofilm formation in an LL-37-dependent manner. Additionally, LL-37 antimicrobial function depends on NET scaffold integrity. Collectively, these data expand the knowledge on the immunomodulatory role of macrolide antibiotics via the generation of LL-37-bearing NETs, which demonstrate LL-37-dependent antimicrobial activity and biofilm inhibition against A. baumannii.

OBJECTIVE: Inflammatory attacks of familial Mediterranean fever (FMF) are characterised by circulation and influx of high number of polymorphonuclear neutrophils (PMN) in the affected sites and profound therapeutic effect of IL-1ß inhibitors. We investigated the role of neutrophil extracellular traps (NET) in the pathogenesis of FMF, and their involvement in IL-1ß production. METHODS: Blood samples were obtained from six FMF patients during remissions and from three patients during attacks. NET formation and NET components were studied by fluorescence techniques, immunobloting and MPO-DNA complex ELISA. RESULTS: PMNs from patients released NETs decorated with IL-1ß during disease attacks. On the other hand, PMNs from patients during remission were resistant to inflammatory stimuli that induce NET release in PMNs from control subjects. Lower basal autophagy levels were identified in PMNs during remission, while induction of autophagy facilitated NET release, suggesting that autophagy is involved in the regulation of NET release. During the resolution of attacks, inhibition of NET formation by negative feedback mechanism was also observed. The anti-inflammatory agents, colchicine and DNAse I, inhibited IL-1ß production in PMNs and IL-1ß activity in NETs, respectively. CONCLUSIONS: We suggest two additive events for triggering the FMF attack; the production of IL-1ß by PMNs and its release through NETs. At the same time NETs, homeostatically, downregulate further NETosis, facilitating the resolution of attack. Compensatorly, lower basal autophagy of PMNs may protect from crises by attenuating the release of pro-inflammatory NETs.

AIMS: Neutrophil extracellular traps (NETs) are chromatin ï¬laments released by activated polymorphonuclear neutrophils (PMNs) and decorated with granule proteins with various properties. Several lines of evidence implicate NETs in thrombosis. The functional significance and the in vivo relevance of NETs during atherothrombosis in humans have not been addressed until now. METHODS AND RESULTS: Selective sampling of thrombotic material and surrounding blood from the infarct-related coronary artery (IRA) and the non-IRA was performed during primary percutaneous revascularization in 18 patients with ST-segment elevation acute myocardial infarction (STEMI). Thrombi isolated from IRA contained PMNs and NETs decorated with tissue factor (TF). Although TF was expressed intracellularly in circulating PMNs of STEMI patients, active TF was specifically exposed by NETs obtained from the site of plaque rupture. Treatment of NET structures with DNase I abolished TF functionality measurement. In vitro treatment of control PMNs with plasma obtained from IRA and non-IRA was further shown to induce intracellular up-regulation of TF but not NET formation. A second step consisting of the interaction between PMNs and thrombin-activated platelets was required for NET generation and subsequent TF exposure. CONCLUSION: The interaction of thrombin-activated platelets with PMNs at the site of plaque rupture during acute STEMI results in local NET formation and delivery of active TF. The notion that NETs represent a mechanism by which PMNs release thrombogenic signals during atherothrombosis may offer novel therapeutic targets.

OBJECTIVE: To monitor microbes, focusing on drug resistance, on the hands of the personnel of four departments of a tertiary hospital (ICU, neonatal unit, internal medicine ward and surgical ward) and explore differences between departments, professions and genders. MATERIALS AND METHODS: Hand sampling from 125 healthcare employees was conducted followed by isolation, identification and antibiotic resistance profiling of different microbial species. RESULTS: Staphylococcus spp was the most prevalent microbe (76/125, 60.8%), followed by different Gram-negative pathogens (45.6%). ICU employees had a significant probability to have Gram-negative contamination [OR 3.627 (95% CI 1.220-10.782)], independently of gender or profession. Staphylococcus spp presence was associated with working in the internal medicine ward [OR 6.976 (95% CI 1.767-25.540)] and the surgical ward [OR 5.795 (95% CI 1.586-21.178)]. Staphylococcus spp was more prevalent in males vs. females (81.3% vs. 54.9%, p=0.008) and in medical vs. nursing personnel (76.9% vs. 54.8, p=0.019). In the majority of Gram-negative isolates (56.1%), at least one multi-drug resistant (MDR) or extensively drug resistant (XDR) strain was isolated. A statistically significant higher prevalence of XDR Gram-negative microbes was found on the hands of nursing personnel (22.2% vs. 2.3% for medical doctors, p=0.014). Only 2 methicillin resistant Staphylococcus Aureus (MRSA) out of the 12 Staphylococcus aureus positive samples were identified. CONCLUSIONS: Employees in the ICU are more prone to Gram-negative and not to Gram-positive hand contamination. MDR and XDR pathogens are prevalent, and are associated with nursing profession.

Neutrophil activation by inflammatory stimuli and the release of extracellular chromatin structures (neutrophil extracellular traps - NETs) have been implicated in inflammatory disorders. Herein, we demonstrate that NETs released by neutrophils treated either with fibrosis-related agents, such as cigarette smoke, magnesium silicate, bleomycin, or with generic NET inducers, such as phorbol 12-myristate 13-acetate, induced activation of lung fibroblasts (LFs) and differentiation into myofibroblast (MF) phenotype. Interestingly, the aforementioned agents or IL-17 (a primary initiator of inflammation/fibrosis) had no direct effect on LF activation and differentiation. MFs treated with NETs demonstrated increased connective tissue growth factor expression, collagen production, and proliferation/migration. These fibrotic effects were significantly decreased after degradation of NETs with DNase1, heparin or myeloperoxidase inhibitor, indicating the key role of NET-derived components in LF differentiation and function. Furthermore, IL-17 was expressed in NETs and promoted the fibrotic activity of differentiated LFs but not their differentiation, suggesting that priming by DNA and histones is essential for IL-17-driven fibrosis. Additionally, autophagy was identified as the orchestrator of NET formation, as shown by inhibition studies using bafilomycin A1 or wortmannin. The above findings were further supported by the detection of NETs in close proximity to alpha-smooth muscle actin (α-SMA)-expressing fibroblasts in biopsies from patients with fibrotic interstitial lung disease or from skin scar tissue. Together, these data suggest that both autophagy and NETs are involved not only in inflammation but also in the ensuing fibrosis and thus may represent potential therapeutic targets in human fibrotic diseases.

BACKGROUND: To study the levels of procalcitonin (PCT) in patients with meningitis and control group and compare them with established markers of infection--such as C-reactive protein (CRP), high-sensitivity CRP, and WBC--in cerebrospinal fluid (CSF) and assess the possible discriminative role of PCT in the differential diagnosis of meningitis from other noninfectious diseases. METHODS: We studied CSF samples of patients from Intensive Care Unit, Internal Medicine, Neurology, Hematology, and Pediatric departments. The total number of patients included in the study was 58. The samples were divided into three groups: group 1 with bacterial meningitis (BM) central nervous system (n = 19); group 2 with viral meningitis (VM, n = 11); and group 3, control group, with noninfectious diseases (n = 28). RESULTS: Values of PCT levels >0.5 ng/ml were considered as abnormal. In group 1, mean PCT levels were 4.714 ± 1.59 ng/ml. In group 2, all patients had PCT <0.5 ng/ml (0.1327 ± 0.03 ng/ml). In group 3, the mean PCT levels were <0.1 ng/ml. CONCLUSION: PCT values in CSF can be very helpful in distinguishing BM from VM and other noninfectious diseases.

Diabetes is known as a "silent epidemic" and is a public health problem that accounts for 9% of all deaths worldwide. The prevention of diabetes is a significant challenge, as its prevalence and incidence are both increasing rapidly. According to the World Health Organization (WHO), education is the cornerstone of diabetes treatment. Since the severity of oral diseases is significantly higher in diabetic patients, this systematic review aims to highlight the oral care of diabetic patients as a priority for glycemic control and the importance of education for diabetic patients' oral health. We evaluated 20 clinical studies and 15 meta-analyses from PubMed and Google Scholar over the last five years. Their main themes are the direct relationship between diabetes and oral health, especially periodontitis, and the necessity of education and behaviors that can lead to a better quality of life. Our analysis indicated that good oral health is a critical factor of glycemic control in diabetic patients and can be enhanced by targeted educational programs, backed by long-term medical and dental follow-up. Healthcare personnel should be encouraged to develop their knowledge of oral health in relation to the disease so that behaviors can be adopted to improve patients' quality of life. Telemedicine could also contribute to patient education and self-management of the disease.
RESUMEN
The nutritional habits regulate the gut microbiota and increase risk of an autoimmune disease. Western diet is rich in sugars, meat, and poly-unsaturated fatty acids, which lead to dysbiosis of intestinal microbiota, disruption of gut epithelial barrier and chronic mucosal inflammation. In contrast, the Mediterranean Diet (MedDiet) is abundant in ω3 fatty acids, fruits, and vegetables, possessing anti-inflammatory properties that contribute to the restoration of gut eubiosis. Numerous studies have extensively examined the impact of MedDiet and its components on both health and various disease states. Additionally, specific investigations have explored the correlation between MedDiet, microbiota, and the risk of autoimmune diseases. Furthermore, the MedDiet has been linked to a reduced risk of cardiovascular diseases, playing a pivotal role in lowering mortality rates among individuals with autoimmune diseases and comorbidities. The aim of the present review is to specifically highlight current knowledge regarding possible interactions of MedDiet with the patterns of intestinal microbiota focusing on autoimmunity and a blueprint through dietary modulations for the prevention and management of disease's activity and progression.
RESUMEN
OBJECTIVES: The aim of this study was to record parents' knowledge and attitudes towards bullying experienced by their children and to explore the strategies they choose to manage bullying incidents. METHODS: A cross-sectional study was conducted. The study population consisted of parents of children who have experienced bullying in a primary or secondary school classroom. The "Parents' Strategies to Cope with Bullying" questionnaire was used to collect data. Regarding parents' coping with bullying, the strategy "Support and advice to the child" scored the highest and the strategy "Social support and information" the next highest. RESULTS: Of the parents, 44.3â¯% had received some information/education regarding the phenomenon of bullying with the most important source of information being reading. According to the results of multivariate linear regression, mothers more often applied the strategy "social support and information" (Coefficient b=0.9, 95â¯% CI for b=0.7 to 1.1, p<0.001) and parents with lower educational level more often applied the strategy "avoidance" (Coefficient b=-0.5, 95â¯% CI for b=-0.8 to -0.2, p=0.004). CONCLUSIONS: School bullying remains a major worldwide phenomenon over time. Although parents choose to support their children, they do not receive information and training on how to manage bullying from a formal institution, making the need for such programs imperative.

BACKGROUND: Autolοgous Hematopoietic Stem Cell Transplantation (AHSCT) is a treatment οption fοr patients with hematological malignancies that improves prοgnοsis and survival. Thus, it is necessary tο deal with its long-term cοmplications, such as sexual dysfunction and trauma that significantly affect survivors' quality οf life. OBJECTIVE: The aim οf this study was to evaluate the Sexual Function (SF) and the Pοst-traumatic Stress Disorder (PTSD) οf survivοrs οf hematolοgical malignancy and AHSCT. METHODS: A multicenter, quantitative, crοss-sectional, descriptive, and cοrrelational study was cοnducted from December 2019 to March 2022. Thrοugh cοnvenience sampling, 127 adults and sexually active survivors οf hematolοgic malignancy whο underwent AHSCT frοm 6 mοnths tο 5 years were recruited frοm 5 hοspitals in Athens. The survivοrs cοmpleted questionnaires on demοgraphic and clinical data, a male or female SF assessment tοοl [Internatiοnal Index Erectile Functiοn (IIEF) and Female Sexual Functiοn Index (FSFI), respectively], and the Impact of Event Scale-Revised (IES-R). RESULTS: Patients' mean age was 45.6 (±12.8) years. The median time frοm transplant was 3 years and the majοrity οf the survivοrs had Hodgkin's lymphοma. Accοrding tο the FSFI, wοmen had a mοderate level of SF, with a better functional area the "pain" and wοrse the "οrgasm". Accοrding tο the IIEF, men had a high level of SF, with a better functional area the "erection" and wοrse the "οverall satisfaction". Survivοrs had lοw levels οf PTSD based οn the IES-R, with nο differences between men and women. The subscale οf "hyperarοusal" had the lοwest values and the subscale οf "avοidance" had the highest values fοr bοth men and wοmen survivοrs. There was a lοw tο mοderate negative statistically significant cοrrelation between the IES-R and bοth FSFI and IIEF, suggesting a high level οf PTSD to be correlated with wοrse sexual function. CONCLUSION: Survivοrs οf AHSCT had impaired SF tο varying degrees and areas of functionality depending οn their gender, but lοw levels of PTSD and lοw correlations between these twο variables. This matter is impοrtant in survivοrship care and needs further investigatiοn.
RESUMEN
Recent findings have identified professional drivers as being at an increased risk of Legionnaires' disease. Our hypothesis was that used car cabin air filters represent a reservoir of Legionella bacteria, and thus a potential pathway for contamination. We analysed used cabin air filters from various types of car. The filters were analysed by culture and by molecular methods. Our findings indicated that almost a third of air filters were colonized with Legionella pneumophila. Here, we present the first finding of Legionella spp. in used car cabin air filters. Further investigations are needed in order to confirm this exposure pathway. The presence of Legionella bacteria in used cabin air filters may have been an unknown source of infection until now.
