Abstract
Sarcopoterium spinosum (L.) Spach is a Rosaceae shrub employed in the folk medicine in the Eastern Mediterranean basin. The previous few studies have focused on the S. spinosum roots, while the fruits have been poorly investigated. The present study aims to assess the biological properties of S. spinosum fruits collected in Lebanon and subjected to ethanolic, water or boiling water extraction. The extracts were compared for the phenol and flavonoid contents, and for the in vitro radical scavenging ability. The ethanolic extract (SEE) was selected and characterized by high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS) showing a phenolome rich in tannins (ellagitannins), flavonoids (quercetin derivatives), and triterpenes. The biological activity of SEE was tested on a cellular model of moderate steatosis consisting of lipid-loaded hepatic cells treated with increasing concentrations of SEE (1-25 μg/mL), or with corilagin or quercetin as comparison. In steatotic hepatocytes the SEE was able (i) to ameliorate the hepatosteatosis; (ii) to counteract the excess ROS and lipid peroxidation; (iii) to restore the impaired catalase activity. The results indicate that the ethanolic extract from S. spinosum fruits is endowed with relevant antisteatotic and antioxidant activities and might find application as nutraceutical product.

Abstract
Abstract
Background
Despite significant progress in cardiopulmonary resuscitation (CPR), outcomes remain relatively poor. Epinephrine administration remains a cornerstone in the treatment of in-hospital cardiac arrest. Various routes of administration, including intravenous, intramuscular, intraosseous and endotracheal routes have been studied; however, the optimal route is debated.
Purpose
The purpose of this study was to compare patient outcomes following peripheral intravenous (IV), central IV, or arterial intracoronary (IC) epinephrine administration in patients undergoing CPR in the catheterization laboratory.
Methods
This was a prospective two-center pilot cohort study conducted in high-volume percutaneous coronary intervention (PCI) facilities in the republic of Lithuania. The study enrolled patients with acute myocardial infarction (AMI) who suffered a cardiac arrest in the cardiac catheterization laboratory during PCI. Cardiac resuscitation was performed according to the European Resuscitation Council Guidelines. Central IV was the first choice for epinephrine administration if it was available. However, in cases without central access, the route of epinephrine administration (peripheral IV or arterial IC) was at the discretion of the physician. The primary endpoint was the rate of return of spontaneous circulation (ROSC). We tested for overall differences in patient characteristics and outcomes between groups using Chi-Square (or Kruskal-Wallis) tests and used the Holm-Bonferroni adjustment (or Dunn's tests) for subsequent pairwise tests. We also performed logistic regression.
Results
There were 158 participants in this study, with 48 (30.4%), 50 (31.6%), and 60 (38.0%) receiving epinephrine via central IV, IC, and peripheral IV routes, respectively. The median age was 71 [61, 80] years and 56% of participants were men. Patient characteristics were similar across routes, except for age (higher for peripheral IV than IC), serum potassium (although no significant post-hoc differences), hemoglobin (lowest in peripheral route), and heart rhythm before CPR (higher rates of electromechanical dissociation in peripheral route). There were 111 (70%) patients who achieved the primary outcome of ROSC (Table 1). Peripheral IV administration was associated with 7-fold decreased odds of achieving ROSC (odds ratio = 0.14, 95% confidence interval = 0.05–0.36, p<0.0001) compared to central IV (no difference between central IV and IC; p=0.9343). By itself, adrenaline route yielded an area under the receiver operating characteristic curve of 0.73, indicating good predictive ability.
Conclusion
Epinephrine administration route was a significant predictor of ROSC for patients with AMI undergoing CPR in the catheterization laboratory. ROSC rates for patients who received epinephrine via IC or central IV were superior to those who received it via peripheral IV.

Abstract
Nonalcoholic fatty liver disease is a metabolic disorder characterized by lipid overloading in hepatocytes that can progress pathogenically and even end in hepatocellular carcinoma. Nonalcoholic fatty liver disease pharmacological treatment is still limited by unwanted side effects, whereas the use of food components with therapeutic potential is advisable. The culinary use of marine algae is traditional for some populations and reviving worldwide, with promising health outcomes due to the large number of bioactive compounds found in seaweeds. The present review focuses on brown-algae polysaccharides, particularly fucoidan, alginate, and laminarin, and summarizes the experimental evidence of their potential effects against nonalcoholic fatty liver disease onset and progression. In vitro and in vivo studies demonstrate that brown-algae polysaccharides exert beneficial actions on satiety feeling, caloric intake, fat absorption, and modulation of the gut microbiota, which could account for indirect effects on energy and lipid homeostasis, thus diminishing the fat overload in the liver. Specific effects against nonalcoholic fatty liver disease pathogenesis and worsening are also described and sustained by the antioxidant, anti-inflammatory, and antisteatotic properties of brown-algae polysaccharides. Further studies are required to clarify the mechanism of action of brown-algae polysaccharides on liver cells, to determine the composition and bioavailability of brown-algae polysaccharides present in different algal sources and to probe the clinical availability of these compounds in the form of algal foods, food supplements, and regulated therapeutics.

Abstract
Fucoidan is a fucose-rich sulfated polysaccharide typically found in the cell wall of marine algae but also recently isolated from terrestrial sources. Due to a variety of biological activities, including antioxidant properties, fucoidan exhibits an attractive therapeutic potential against a wide array of metabolic diseases associated with oxidative stress. We used FTIR, 1H NMR and 13C NMR spectroscopy to investigate the structural features of a fucoidan fraction extracted from the brown alga Cystoseira compressa (CYS). The antioxidant potential of CYS was measured by DPPH, ABTS and FRAP assays, which revealed a radical scavenging capacity that was confirmed in in vitro cellular models of hepatic and endothelial cells. The same antioxidant effects were observed for another fucoidan fraction previously identified in the terrestrial tree Eucalyptus globulus (EUC). Moreover, in hepatic cells, CYS and EUC exhibited a significant antisteatotic action, being able to reduce intracellular triglyceride content through the regulation of key genes of hepatic lipid metabolism. EUC exerted stronger antioxidant and antisteatotic effects as compared to CYS, suggesting that both marine and terrestrial sources should be considered for fucoidan extraction and therapeutic applications.

Abstract
Fucoidan is a fucose-rich sulfated polysaccharide with attractive therapeutic potential due to a variety of biological activities, including antioxidant action. Fucoidan is typically found in the cell wall of marine brown algae, but extra-algal sources have also been discovered. In the present work, for the first time we extracted a water soluble fucoidan fraction from the roots of the terrestrial shrub Ferula hermonis. This fucoidan fraction was termed FUFe, and contained fucose, glucose, sulfate, smaller amounts of monosaccharides such as galactose and mannose, and a minor quantity of proteins. FUFe structural features were investigated by FTIR, 1H NMR and 13C NMR spectroscopy. The antioxidant property of FUFe was measured by DPPH, ABTS and FRAP assays, which revealed a high radical scavenging capacity that was confirmed in in vitro cellular models. In hepatic and endothelial cells, 50 μg/mL FUFe could reduce ROS production induced by intracellular lipid accumulation. Moreover, in hepatic cells FUFe exhibited a significant antisteatotic action, being able to reduce intracellular triglyceride content and to regulate the expression of key genes of hepatic lipid metabolism. Altogether, our results candidate FUFe as a possible bioactive compound against fatty liver disease and related vascular damage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ephedra foeminea is a member of the Ephedraceae family which is widespread in the eastern Mediterranean area. In Lebanon, Ephedra is a popular remedy in traditional medicine to prevent and/or counteract many stress oxidative-related diseases like inflammation and bacterial infections. AIM OF THE STUDY Oxidative stress leads to endothelial cell dysfunction, and is a major factor contributing to etiology of atherosclerosis and related diseases. This study aims to investigate the antioxidant and cytoprotective potential of extracts from E. foeminea fruits on human endothelial cells exposed to hydrogen peroxide (H2O2) to mimic in vitro vascular endothelium dysfunction. MATERIALS AND METHODS Different extracts of E. foeminea fruits were prepared using pure ethanol (EE), methanol/water (EMW), pure hexane (Ehex) or ethyl acetate/water (Epoly) as extraction solvents. The phenolome profile of each extract was characterized using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS). Total phenolic and flavonoid content, and radical scavenging properties of the extracts were assessed spectrophotometrically. Then, the effects on human endothelial cells HECV were evaluated. RESULTS Epoly extract showed the highest phenol and flavonoid content, and the highest radical scavenging capacity. On H2O2-insulted HECV cells Epoly was able: (i) to counteract the ROS/RNS production and lipid peroxidation; (ii) to rescue the ROS-dependent decrease in the mitochondrial membrane potential; (iii) to counteract the apoptosis induction; (iv) to restore endothelial cell viability and migration. CONCLUSIONS The findings indicated that the polyphenol-enriched extract Epoly from E. foeminea fruits is endowed with in vitro anti-oxidant and anti-apoptotic effects and might be used as nutraceutical for treating ROS-related endothelium dysfunction and inflammation.

Abstract
Thyme-like plants including Thymbra spicata L. are widely used as food and folk medicinal remedies in the Mediterranean area. This study aimed to explore the in vitro antitumor potential of polyphenol-enriched extracts from aerial parts of T. spicata. The ethanolic extract significantly inhibited proliferation of different human tumor cell lines, without significant effects on non-neoplastic cells. A deeper investigation of the molecular mechanism sustaining the in vitro antitumor activity of the extract was carried on the human breast cancer cells MCF-7 in comparison with the normal breast cells MCF-10A. The effects on MCF-7 cells were associated with the following: (i) production of reactive oxygen species (ROS) and release of nitric oxide; (ii) apoptosis induction; and (iii) reduction in STAT3 and NF-kB phosphorylation. The ethanolic extract from T. spicata leaves might represent a novel therapeutic tool in combination with conventional chemotherapy to reduce the adverse side effects and drug resistance.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thymbra spicata, a member of the Lamiaceae family, is native to eastern Mediterranean area. Leaves of this plant are rich in phenolic compounds and are a popular remedy of traditional medicine in Lebanon to prevent and/or counteract hyperlipidemia and hyperglycemia. AIM OF THE STUDY To evaluate the antisteatotic and antioxidant activities of extracts from leaves of Thymbra spicata L. using in vitro models of non-alcoholic fatty liver disease (NAFLD), a leading cause of liver-related morbidity and mortality worldwide, for whom no effective treatments are still available. MATERIALS AND METHODS Two different extracts from Thymbra spicata L. aerial parts were prepared using water (TW) or ethanol (TE) as solvent. Their chemical composition was characterized by gas and liquid chromatography coupled with mass spectrometry. Both extracts were tested on cultured hepatic and endothelial cells treated to mimic in vitro a multisistemic pathology such as NAFLD. We assayed the effects on lipid accumulation, free radical production, lipid peroxidation, cell migration. RESULTS Both the total phenolic and the total flavonoid contents were higher in the ethanolic extract. Rosmarinic acid was the most abundant polyphenol in TW, while TE was richer in carvacrol. Our findings demonstrated that both extracts ameliorated lipid accumulation, oxidative stress and inflammation in the NAFLD cellular models. However, the aqueous extract was more effective to reduce hepatic steatosis, and the ethanolic extract had higheranti-oxidant potential and wound healing activity. CONCLUSIONS T. spicata extracts could be promising bioactive products to develop natural therapeutic agents or dietary supplements to treat NAFLD and obesity-related metabolic disease. Our findings suggest that while the ethanolic extract might be used in preventing endothelium dysfunction, the aqueous extract would act better as lipid-lowering agent.

Abstract
IntroductionSatisfaction of patients with in-patient care is a relatively rare focus of research in mental health.ObjectivesThe IDEA-study (inpatient discharge: experiences and analysis) was initiated to shed the light on the issue internationally.AimThe IDEA project aimed to:– develop a collaborative network of young psychiatrists;– use this network to explore satisfaction of people treated in psychiatric in-patient facilities in a range of high-, middle- and low-income countries.MethodsStudy was conducted in 25 hospitals across 11 countries. We measured satisfaction with in-patient care using the 5-item study-specific questionnaire. Individual and institution level correlates of “low satisfaction” were examined by comparisons of binary and multivariate associations in multilevel regression models.ResultsA final study sample consisted of 673 participants. Total satisfaction scores were highly skewed towards positive responses. After taking clustering into account, the only independent correlates of low satisfaction were schizophrenia diagnosis and low psychiatrist to patient ratio.ConclusionWe could successfully establish a collaborative network of early career psychiatrists from different parts of the world and collect data in regards to the study aims. The positive skew of satisfaction scores need to be carefully considered in the context of literature and study limitations. In particularly, we suggest further studies on patients’ satisfaction to pay more attention to treatment expectations formed by the previous experience of treatment, service-related knowledge, stigma and patients’ disempowerment, power imbalance.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Little is known about the relative extent of crime against people with severe mental illness (SMI). AIMS To assess the prevalence and impact of crime among people with SMI compared with the general population. METHOD A total of 361 psychiatric patients were interviewed using the national crime survey questionnaire, and findings compared with those from 3138 general population controls participating in the contemporaneous national crime survey. RESULTS Past-year crime was experienced by 40% of patients v. 14% of controls (adjusted odds ratio (OR) = 2.8, 95% CI 2.0-3.8); and violent assaults by 19% of patients v. 3% of controls (adjusted OR = 5.3, 95% CI 3.1-8.8). Women with SMI had four-, ten- and four-fold increases in the odds of experiencing domestic, community and sexual violence, respectively. Victims with SMI were more likely to report psychosocial morbidity following violence than victims from the general population. CONCLUSIONS People with SMI are at greatly increased risk of crime and associated morbidity. Violence prevention policies should be particularly focused on people with SMI.

Abstract
BACKGROUND Domestic and sexual violence are significant public health problems but little is known about the extent to which men and women with severe mental illness (SMI) are at risk compared with the general population. We aimed to compare the prevalence and impact of violence against SMI patients and the general population. METHOD Three hundred and three randomly recruited psychiatric patients, in contact with community services for ⩾ 1 year, were interviewed using the British Crime Survey domestic/sexual violence questionnaire. Prevalence and correlates of violence in this sample were compared with those from 22 606 general population controls participating in the contemporaneous 2011/12 national crime survey. RESULTS Past-year domestic violence was reported by 27% v. 9% of SMI and control women, respectively [odds ratio (OR) adjusted for socio-demographics, aOR 2.7, 95% confidence interval (CI) 1.7-4.0], and by 13% v. 5% of SMI and control men, respectively (aOR 1.6, 95% CI 1.0-2.8). Past-year sexual violence was reported by 10% v. 2.0% of SMI and control women respectively (aOR 2.9, 95% CI 1.4-5.8). Family (non-partner) violence comprised a greater proportion of overall domestic violence among SMI than control victims (63% v. 35%, p < 0.01). Adulthood serious sexual assault led to attempted suicide more often among SMI than control female victims (53% v. 3.4%, p < 0.001). CONCLUSIONS Compared to the general population, patients with SMI are at substantially increased risk of domestic and sexual violence, with a relative excess of family violence and adverse health impact following victimization. Psychiatric services, and public health and criminal justice policies, need to address domestic and sexual violence in this at-risk group.

Abstract
Backgrounds. The extent to which psychiatric disorders are associated with an increased risk of violence to partners is unclear. This review aimed to establish risk of violence against partners among men and women with diagnosed psychiatric disorders. Methods. Systematic review and meta-analysis. Searches of eleven electronic databases were supplemented by hand searching, reference screening and citation tracking of included articles, and expert recommendations. Results. Seventeen studies were included, reporting on 72 585 participants, but only three reported on past year violence. Pooled risk estimates could not be calculated for past year violence against a partner and the three studies did not consistently report increased risk for any diagnosis. Pooled estimates showed an increased risk of having ever been physically violent towards a partner among men with depression (odds ratio (OR) 2.8, 95% confidence intervals (CI) 2.5-3.3), generalized anxiety disorder (GAD) (OR 3.2, 95% CI 2.3-4.4) and panic disorder (OR 2.5, 95% CI C% 1.7-3.6). Increased risk was also found among women with depression (OR 2.4, 95% CI 2.1-2.8), GAD (OR 2.4, 95% CI 1.9-3.0) and panic disorder (OR 1.9, 95% CI 1.4-2.5). Conclusions. Psychiatric disorders are associated with high prevalence and increased odds of having ever been physically violent against a partner. As history of violence is a predictor of current violence, mental health professionals should ask about previous partner violence when assessing risk.

Abstract
BACKGROUND Cutaneous leishmaniasis is an infection that has spread to non-endemic regions, stimulating recent interest for the enhanced understanding of this disease. Downregulation of the CD1a receptor on Langerhans cells has been described in various cutaneous infections. OBJECTIVE In this study, the immune response across different Ridley patterns and parasitic indices is outlined in a case series of cutaneous leishmaniasis. METHODS Skin punch biopsies from the interface of normal and lesional cutaneous leishmaniasis were collected from 33 patients with molecularly confirmed Leishmania tropica or L. major infection. Ridley patterns (2-5) were assessed for various clinicopathological features including age, gender, disease duration, parasitic index and constituents of the inflammatory infiltrate. CD1a, CD68, CD3, CD4, CD8, CD20 and CD138 stains were performed on normal skin tissue, cutaneous leishmaniasis biopsies and cytospin/cell block cytology preparations of cultured leishmania promastigotes. CD1a was quantified per mm2 in the epidermis and dermis. The remaining stains were graded according to a 4-tiered grading system [0 (0-4%); 1 (5-24%); 2 (25-49%); 3 (50-74%) and 4 (75-100%). RESULTS Total CD1a expression significantly decreased (14-fold) from parasitic indices (0-2) to (5-6); (ρ < 0.001). CD1a expression in the epidermis was at least 5-fold lower than normal skin (58 vs. 400 cells/mm2), inversely correlating with the parasitic index. There was an increase in dermal CD1a Langerhans cells (33 vs. 0 cells/mm² in the dermis). CD1a and CD68 staining of amastigotes was strong and diffuse, whereas promastigotes were negative. The major inflammatory infiltrate, in all Ridley patterns, consisted of macrophages and double-negative CD3(+) CD4(-) CD8(-) T lymphocytes. The double-negative CD3 T cells formed a ring around the parasitic laden macrophages. Apart from CD1a, there was no significant difference in inflammatory markers between the various Ridley patterns and parasitic indices. Disease duration did not correlate with Ridley pattern. CONCLUSION The significant decrease in CD1a expression is postulated by two mechanisms; either via direct CD1a receptor uptake by leishmania amastigotes and/or negative feedback inhibition of CD1a Langerhans cells by double-negative CD3 T-regulatory cells. Modulation of the immune microenvironment in cutaneous leishmaniasis represents a potential therapeutic and prophylactic target.

Abstract
Aims. To assess the extent to which being a victim of intimate partner violence (IPV) is associated with psychiatric disorders in men and women. Methods. A stratified multistage random sample was used in the third English psychiatric morbidity survey. Psychiatric disorders were measured by the Clinical Interview Schedule (Revised) and screening questionnaires. IPV was measured using British Crime Survey questions. Results. 18.7% (95% CI 17.1-20.4; n = 595 of 3197) of men had experienced some form of IPV compared with 27.8% of women (95% CI 26.2-29.4; n = 1227 of 4206; p < 0.001). IPV was associated with all disorders measured (except eating disorders in men). Physical IPV was significantly linked to psychosis and with substance and alcohol disorders in men and women, but significant associations with common mental disorders (CMDs), post-traumatic stress disorder (PTSD) and eating disorders were restricted to women. Emotional IPV was associated with CMDs in men and women. Conclusions. The high prevalence of experiences of partner violence, and strength of the association with every disorder assessed, suggests enquiry about partner violence is important in identifying a potential risk and maintenance factor for psychiatric disorders, and to ascertain safety, particularly in women as they are at greatest risk of being victims of violence.

Abstract
BACKGROUND The lifetime prevalence of domestic violence in women is 20-25%. There is increasing recognition of the increased vulnerability of psychiatric populations to domestic violence. We therefore aimed to review studies on the prevalence of, and the evidence for the effectiveness of interventions in, psychiatric patients experiencing domestic violence. METHOD Literature search using Medline, PsycINFO and EMBASE applying the following inclusion criteria: English-language papers, data provided on the prevalence of or interventions for domestic violence, adults in contact with mental health services. RESULTS Reported lifetime prevalence of severe domestic violence among psychiatric in-patients ranged from 30% to 60%. Lower rates are reported for men when prevalence is reported by gender. No controlled studies were identified. Low rates of detection of domestic violence occur in routine clinical practice and there is some evidence that, when routine enquiry is introduced into services, detection rates improve, but identification of domestic violence is rarely used in treatment planning. There is a lack of evidence on the effectiveness of routine enquiry in terms of morbidity and mortality, and there have been no studies investigating specific domestic violence interventions for psychiatric patients. CONCLUSIONS There is a high prevalence of domestic violence in psychiatric populations but the extent of the increased risk in psychiatric patients compared with other populations is not clear because of the limitations of the methodology used in the studies identified. There is also very limited evidence on how to address domestic violence with respect to the identification and provision of evidence-based interventions in mental health services.

Abstract
L-asparaginase is a critical component in the treatment of acute lymphoblastic leukemia in children. It is known to cause coagulation abnormalities, thrombosis and hemorrhage in the central nervous system in addition to vasculitis and hypersensitivity reactions. The purpose of this article is to present the first case-series of posterior reversible encephalopathy syndrome (PRES) associated with L-asparaginase treatment. We report 3 cases of children with acute lymphoblastic leukemia who developed seizures and altered sensorium after L-asparaginase therapy. MRI showed increased T(2) signal intensity predominant in the posterior regions of the brain suggestive of PRES. Two of our patients developed septic shock and deteriorated whereas one patient improved and recovered completely.
