Abstract
Personalized nutrition (PN) has gained much attention as a tool for empowerment of consumers to promote changes in dietary behavior, optimizing health status and preventing diet related diseases. Generalized implementation of PN faces different obstacles, one of the most relevant being metabolic characterization of the individual. Although omics technologies allow for assessment the dynamics of metabolism with unprecedented detail, its translatability as affordable and simple PN protocols is still difficult due to the complexity of metabolic regulation and to different technical and economical constrains. In this work, we propose a conceptual framework that considers the dysregulation of a few overarching processes, namely Carbohydrate metabolism, lipid metabolism, inflammation, oxidative stress and microbiota-derived metabolites, as the basis of the onset of several non-communicable diseases. These processes can be assessed and characterized by specific sets of proteomic, metabolomic and genetic markers that minimize operational constrains and maximize the information obtained at the individual level. Current machine learning and data analysis methodologies allow the development of algorithms to integrate omics and genetic markers. Reduction of dimensionality of variables facilitates the implementation of omics and genetic information in digital tools. This framework is exemplified by presenting the EU-Funded project PREVENTOMICS as a use case.

Abstract
Background COVID-19 infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause mild symptoms to severe illness and death. Co-infections of SARS-CoV-2 with other respiratory viruses have been described. However, two SARS-CoV-2 lineage co-infection have been rarely reported. Methodology A genotyping analysis and two different types of whole genome sequencing were performed (Illumina MiniSeq and ONT MinION). When examining the phylogenetic analysis in NextClade and Pangolin webservers, and considering the genotyping findings, conflicting results were obtained. Results The raw data of the sequencing was analyzed, and nucleotide variants were identified between different reads of the virus genome. B.1 and P.1 lineages were identified within the same sample. Conclusions We concluded that this is a co-infection case with two SARS-CoV-2 lineages, the first one reported in Ecuador.

Abstract
BACKGROUND & AIMS Growing evidence suggests that biomarker-guided dietary interventions can optimize response to treatment. In this study, we evaluated the efficacy of the PREVENTOMCIS platform-which uses metabolomic and genetic information to classify individuals into different 'metabolic clusters' and create personalized dietary plans-for improving health outcomes in subjects with overweight or obesity. METHODS A 10-week parallel, double-blinded, randomized intervention was conducted in 100 adults (82 completers) aged 18-65 years, with body mass index ≥27 but <40 kg/m2, who were allocated into either a personalized diet group (n = 49) or a control diet group (n = 51). About 60% of all food was provided free-of-charge. No specific instruction to restrict energy intake was given. The primary outcome was change in fat mass from baseline, evaluated by dual energy X-ray absorptiometry. Other endpoints included body weight, waist circumference, lipid profile, glucose homeostasis markers, inflammatory markers, blood pressure, physical activity, stress and eating behavior. RESULTS There were significant main effects of time (P < 0.01), but no group main effects, or time-by-group interactions, for the change in fat mass (personalized: -2.1 [95% CI -2.9, -1.4] kg; control: -2.0 [95% CI -2.7, -1.3] kg) and body weight (personalized: -3.1 [95% CI -4.1, -2.1] kg; control: -3.3 [95% CI -4.2, -2.4] kg). The difference between groups in fat mass change was -0.1 kg (95% CI -1.2, 0.9 kg, P = 0.77). Both diets resulted in significant improvements in insulin resistance and lipid profile, but there were no significant differences between groups. CONCLUSION Personalized dietary plans did not result in greater benefits over a generic, but generally healthy diet, in this 10-week clinical trial. Further studies are required to establish the soundness of different precision nutrition approaches, and translate this science into clinically relevant dietary advice to reduce the burden of obesity and its comorbidities.

Abstract
INTRODUCTION Personalised nutrition holds immense potential over conventional one-size-fits-all approaches for preventing and treating diet-related diseases, such as obesity. The current study aims to examine whether a personalised nutritional plan produces more favourable health outcomes than a standard approach based on general dietary recommendations in subjects with overweight or obesity and elevated waist circumference. METHODS AND ANALYSIS This project is a 10-week parallel, double-blinded randomised intervention trial. We plan to include 100 adults aged 18-65 years interested in losing weight, with body mass index ≥27 but<40 kg/m2 and elevated waist circumference (males >94 cm; females >80 cm). Participants will be categorised into one of five predefined 'clusters' based on their individual metabolic biomarker profile and genetic background, and will be randomised in a 1:1 ratio to one of two groups: (1) personalised plan group that will receive cluster-specific meals every day for 6 days a week, in conjunction with a personalised behavioural change programme via electronic push notifications; or (2) control group that will receive meals following the general dietary recommendations in conjunction with generic health behaviour prompts. The primary outcome is the difference between groups (personalised vs control) in the change in fat mass from baseline. Secondary outcomes include changes in weight and body composition, fasting blood glucose and insulin, lipid profile, adipokines, inflammatory biomarkers, and blood pressure. Other outcomes involve measures of physical activity and sleep patterns, health-related quality of life, dietary intake, eating behaviour, and biomarkers of food intake. The effect of the intervention on the primary outcome will be analysed by means of linear mixed models. ETHICS AND DISSEMINATION The protocol has been approved by the Ethics Committee of the Capital Region, Copenhagen, Denmark. Study findings will be disseminated through peer-reviewed publications, conference presentations and media outlets. TRIAL REGISTRATION NUMBER NCT04590989.

Abstract
Abstract
Background
Autoimmune myocarditis is a cause of dilated cardiomyopathy and heart failure. Recent studies have indicated that leaky gut may allow environmental factors to enter the body and trigger the initiation/development of autoimmune disease. Moreover, there is a growing literature supporting that, beside myocardial fibrosis, a leaky intestinal barrier and gut dysbiosis are pathogenic factors linked to heart failure. The natural triterpene oleanolic acid (OA) has been shown to beneficially influence the severity of the experimental autoimmune myocarditis (EAM), a preclinical model of human myocarditis, via anti-oxidant and immunomodulatory mechanisms. Herein, we investigate gastrointestinal (GI) disturbances and the gut microbiota composition associated with EAM as potential therapeutic target of OA.
Methods and results
BALB/c mice were α-myosin-inmunized to induce EAM and treated with OA (25 mg/kg/day, i.p). On day 21, heart fibrosis and parameters related to gut damage such as oxidative stress (O2- ions, lipid peroxidation), gut permeability (D-lactate; I-FABP), inflammation and mucins were determined in serum and/or colon. Fecal microbial profiles were identified by 16S rRNA gene sequencing analysis. Firstly, histological analysis of hearts showed presence of fibrosis (Sirius Red stain) in EAM mice, whereas these effects were not detectable in myocardium from healthy or OA-treated EAM mice. In addition, OA preserved the mucin-containing goblet cells along the colon (Alcian Blue/PAS stain). Consistently, serum levels of the epithelial gut damage markers, including D-lactate and iFABP were significantly reduced in OA treated-EAM mice. The beneficial OA effects also included a decrease in the pro-inflammatory mediators sPLA2-IIA and IL-1β and a protection from the oxidative stress response (DHE stain and TBARS) in serum and colonic tissue of EAM-mice. Furthermore, gut microbiota composition showed a lower bacterial diversity and different relative abundance of certain bacterial taxa in EAM-mice compared to control mice. The families of Muribaculaceae, Lachnospiraceae, and Ruminococcaceae were significantly affected in EAM mice, and only Muribaculaceae recovered levels similar to the healthy-control group, after treatment with OA.
Conclusion
Our data show that in addition to the heart, the intestinal barrier and gut microbiota are altered in myocarditis, and that OA treatment could ameliorate this profile. Our data contribute to the idea that gut dysbiosis and GI dysfunction influences myocarditis pathogenesis, and provides new findings regarding the beneficial activity of OA in EAM, suggesting that it may be an interesting candidate to be explored for the treatment of human patients.

Abstract
Reduction of maternal mortality remains a major public health issue worldwide. In France, the latest national confidential enquiry regarding maternal mortality (2010-2012) stated a ratio of 10 /100 000 livebirths whereas the goal was 5/100 000. The risk of death among pregnant women from Subsaharan Africa (SSA) was 3 times higher.
We performed a monocentric observational retrospective study from 01/01/2009 to 01/09/2016 in order to better understand the factors of maternal morbidity among SSA pregnant women. Demographic characteristics as well as pregnancy outcomes were collected. Antenatal clinics attendance was scored (+1 if positive, +1 if done following the recommended schedule). A total 1 489 (7%) out of 20 755 pregnancies were registred among SSA women. Mean age was 29 years (14-48), mean gestity/parity were respectively 3.5 and 1.8. About 38% of pregnancies occured in overweight or obese women. Obstetrical complications were seen in 542 (36%) pregnancies: gestational diabetes (n = 206, 36,4%), hypertensive disorders (n = 122, 8,2%), 19 had both. Pre-eclampsia represented 4%, sepsis 5%, premature rupture of membrane 5% and post partum haemorrhage 3%. Livebirths was high (97%) with a mean gestational age of 37(22-41), a mean birth weight of 3150g (500-5000). The unique maternal death in this cohort was due to amniotic fluid embolism. Complication risk factors were age (30 versus 28 years; p < 0.0001), BMI (26 versus 25 kg/m2; p < 0.0001), past history of chronic hypertension and pregestational diabetes (p < 0,001). Furthermore, the score of antenatal care attendance was low in those who presented pregnancy morbidities (p = 0.0006) (adjusted with age, BMI> 25 and chronic hypertension).
Higher risk of maternal morbidity among SSA women is not only explained by individual risk factors but also by a lack of compliance to the recommended antenatal care even if they live in France. Further investigations including sociological studies are therefore needed.
Key messages
Maternal mortality and morbidity are higher among migrant women from Subsaharan Africa. Our study highlights a non compliance to the recommended antenatal care surveillance among risk factors.

Abstract
Abstract
Purpose
Myocarditis and dilated cardiomyopathy represent the acute and chronic phases of an inflammatory disease of the myocardium, for which no standardized treatment is currently available in clinical practice. Myocardial fibrosis an oxidative stress are pathogenic factors associated with these processes. However, new research has found that gut health can be linked to some cardiac conditions. Thus, in this study we investigated whether intestinal disturbances are present in myocarditis, using a murine experimental autoimmune model (EAM) that mimics human myocarditis, as well as the potential beneficial effect of treatment with the mitochondrial antioxidant, MitoQ.
Methods and results
EAM was induced in BALB/c mice with a myocardiogenic peptide and mice were treated with MitoQ (50 mg/kg/day, i.p). On day 21 (acute phase), we assessed signs of heart injury (e.g. hypertrophy, fibrosis, oxidative stress) and parameters related to gut damage such as accumulation of reactive oxigen species (superoxide anion: O2·−), inflammation (IL-1β, IL-33, TNFα), microbial translocation (sCD14; intestinal fatty acid binding protein, I-FABP) and mucins in serum and/or intestine. MitoQ teatment significantly reduced the high heart weight/body weight ratio (HW/BW) of EAM mice, a characteristic hallmark of cardiac hyperthropy. Histological analysis of hearts showed presence of fibrosis (Sirius Red stain) and high O2·− levels (DHE stain) in EAM mice whereas these effects were not detectable in cardiac tissue from healthy or MitoQ-treated EAM mice. In addition, the enhanced O2·− ions (DHE stain) and mucin loss (Alcian Blu/PAS stain) found in colon, ileum, jejunum and duodenum sections from EAM mice were attenuated by MitoQ treatment. The systemic markers associated to intestinal barrier disruption, sCD14 and I-FABP, were found strongly increased in serum from EAM mice, and MitoQ prevents this rise. The beneficial MitoQ effects were also associated with a decrease in the pro-inflammatory cytokines TNFα, IL-33 and IL-1β, both in serum and colonic tissue of treated-EAM mice, as well as a reduction of the myeloperoxidase activity in colon, compared with untreated EAM mice.
Conclusion
Our data show that in addition to the heart, the intestinal tissue is also damaged in the preclinical model of experimental autoimmune myocarditis, and that MitoQ treatment could reverse this profile. Since there are systemic markers released from the intestine, therapeutic strategies targeting to prevent the intestinal oxidative stress and its associated gut barrier dysfunction, could contribute to the amelioration of the disease.

Abstract
INTRODUCTION Syphilis is a sexually transmitted disease. All organs might be affected, but ocular syphilis only occurs in 0.6 percent of patients. We collected all cases of ocular syphilis requiring hospitalization at the University Hospital Center (UHC) in Marseille in 2017. PATIENTS AND METHODS This was a retrospective monocentric study. The diagnosis of ocular syphilis was based on the combination of ocular inflammation with a positive syphilitic serology. For each patient, sex, age, HIV status, ocular and extraocular symptoms, initial visual acuity, syphilis serology, cerebrospinal fluid (CSF) analysis if done, treatment and clinical response were collected. RESULTS Ten men and two women, aged 28 to 86 years, were hospitalized. Two patients were HIV-positive. Ophtalmological lesions were heterogeneous the posterior structures were most affected. Anterior uveitis was isolated in one patient. Five patients had extraocular signs with cutaneous and/or mucosal involvement. No patient had neurological symptoms. Diagnosis of neurosyphilis through CSF analysis was definite for one patient, probable for 5 patients and ruled out for 2 patients. Six patients received treatment with penicillin G and six with ceftriaxone. Visual acuity improved in all cases. DISCUSSION Ophtalmic cases of syphilis have become more frequent over the past few years in France. The diagnosis should be suspected in cases of eye inflammation even in the absence of favourable clinical presentation or anamnesis. Search for HIV co-infection should be systematic. Our study shows that ceftriaxone remains an effective alternative to penicillin G.

Abstract
PURPOSE Up to 75% of patients with prostate cancer experience metastatic bone disease, which leads to an increased risk for skeletal-related events (SREs) including pathological bone fracture, spinal cord compression, and hypercalcemia of malignancy. Our objective was to systematically review the literature on the impact of SREs on quality of life (QOL), morbidity, and survival with a primary focus on the impact of SREs on pain in prostate cancer patients. METHODS We searched PubMed, limiting to peer-reviewed English-language human studies published in 2000-2010. The search was based on the US Food and Drug Administration and European Medicines Agency definition of an SRE, which includes pathologic fracture, spinal cord compression (SCC), hypercalcemia of malignancy, and radiotherapy or surgery to bone resulting from severe bone pain. RESULTS A total of 209 articles were screened, of which 173 were excluded, and 36 were included in this review. Patients with SREs had more pain and worse survival compared with no SREs. Pathologic bone fractures worsened QOL and were associated with shorter survival. Radiation therapy of SCC alleviated pain and improved morbidity. SCC was associated with decreases in patient survival. Radiation therapy and surgery to bone improved pain. CONCLUSIONS Specific SREs are associated with worse outcomes, including increased pain, poorer QOL, morbidity, and survival. Treatment of SREs is associated with improved pain, although there remains a need for more effective treatment of SREs in prostate cancer patients.

Abstract
Malignant cells in the peripheral blood of patients with solid tumours are of considerable importance for the prognosis and therapeutic correlation. Their detection however is difficult due to lack of sensitivity, specificity and technical problems in standardisation. In this original article we show a new sensitive method overcoming the hitherto known difficulties by combining traditional antibody-techniques with a RT-PCR. Due to this method 2 tumour cells within 5 ml of peripheral blood can be detected in spiking experiments.

Abstract
E-6375 (4-butoxy-2-[4-(2-cyanobenzoyl)-1-piperazinyl] pyrimidine hydrochloride) is a new intravenous general anaesthetic with an anaesthetic potency, in mice, comparable to propofol, or etomidate. Here, we examined the effect of E-6375 upon the GABAA receptor, a putative target of intravenous anaesthetic action. E-6375 reversibly enhanced GABA-evoked currents mediated by recombinant GABAA (alpha1beta2gamma2L) receptors expressed in Xenopus laevis oocytes, with little effect on NMDA- and kainate-evoked currents mediated by NR1a/NR2A and GluR1o/GluR2o glutamate receptors, respectively. E-6375 prolonged the decay of GABA-evoked miniature inhibitory postsynaptic currents recorded from rat Purkinje neurones demonstrating the anaesthetic also enhanced the activity of synaptic GABAA receptors. The GABA enhancing action of E-6375 on recombinant GABAA receptors was unaffected by the subtype of the alpha isoform (i.e. alphaxbeta2gamma2L; x=1-3) within the receptor, but was increased by the omission of the gamma2L subunit. Receptors incorporating beta2, or beta3, subunits were more sensitive to modulation by E-6375 than those containing the beta1 subunit. The selectivity of E-6375 was largely governed by the identity (serine or asparagine) of a single amino acid residue within the second transmembrane domain of the beta-subunit. The various in vivo actions of general anaesthetics may be mediated by GABAA receptor isoforms that have a differential distribution within the CNS. The identification of agents, such as E-6375, that discriminate between GABAA receptor subtypes may augur the development of general anaesthetics with an improved therapeutic profile.

Abstract
Previous estimates of Medicare beneficiaries total and out-of-pocket spending on outpatient prescription drugs have largely been based on data from the 1995 Medicare Current Beneficiary Survey and have focused on how expenditures vary among beneficiaries with different demographic characteristics. This paper reports the results of an analysis of prescription claims from 1998 for more than 375,000 elderly persons whose prescription benefit was managed by Merck-Medco Managed Care. In addition to examining how total and out-of-pocket drug spending in a well-insured population varies by age and sex, we report how total and condition-specific drug spending varies for elderly persons with ten common chronic diseases. Our results illustrate the highly skewed nature of prescription drug spending, even among those with drug coverage, and underscore the particularly high cost burden that pharmaceuticals place on elderly people with chronic diseases.

Abstract
BACKGROUND Most patients with osteoarthritis (OA) are treated by primary care physicians (in this article, primary care physicians are family physicians and general internists). OBJECTIVE To describe and compare the self-reported practice patterns of family physicians and general internists for the evaluation and management of severe OA of the knee, including factors that might influence referral for total knee replacement. DESIGN, SETTING, AND PARTICIPANTS A survey was developed and mailed to randomly selected community family physicians and general internists practicing in Indiana. MAIN OUTCOME MEASURE Self-reported physician practice patterns regarding OA of the knee. RESULTS Physical examination was the most common method of evaluating OA of the knee. Family physicians were more likely to examine for crepitation, joint stability, and quadriceps muscle strength than were general internists (P<.05). Patients with OA of the knee treated by family physicians were more likely to receive nonsteroidal anti-inflammatory drugs or oral corticosteroids and were less likely to receive aspirin, acetaminophen, or narcotics compared with patients treated by general internists. Six patient characteristics were rated as positive factors favoring a referral for possible total knee replacement, 8 characteristics were rated as negative, and 5 were rated as not a factor in the decision about referral. CONCLUSIONS Results from this study suggest that additional research is needed to determine the evaluative techniques for OA of the knee that provide the most useful information for management decisions, the management techniques that maximize patient outcomes, and the criteria that should be used to select patients who would benefit most from referral for possible total knee replacement.

Abstract
OBJECTIVE The long-run cost savings potential of private sector reform efforts, such as selective contracts with providers, depends in part on the relationship between procedure-specific volume and average hospital resources that are consumed in treating patients associated with that specific procedure. Study examines a model that estimates the relationship between hospital procedure-specific volume and average hospital treatment costs, using an elective surgical procedure as an example. DATA SOURCES Medicare Provider Analysis and Review (MedPAR) files for 1989 for hospitalizations in which a Medicare beneficiary received a knee replacement (KR) surgery during 1989. Hospital information was obtained from the American Hospital Association's 1989 Annual Survey. All patient-level data were aggregated to the hospital level to create a data file, with the hospital as the unit of observation. STUDY DESIGN This study used administrative claims data and regression analysis to estimate the effect of hospital procedure-specific volume on average hospital treatment costs of patients receiving KR surgery. We also examined the stability of the volume-cost relationship across hospitals of different sizes. PRINCIPAL FINDING The average treatment costs associated with KR surgery are inversely related to a hospital's KR volume in the regression equation estimated using all hospitals performing KR surgery. The inverse relationship between cost and volume is found to be robust for different-size hospitals. CONCLUSIONS The potential cost savings associated with performing KR surgery at incrementally higher hospital volume level can amount to as much as 10 percent of the hospital's average treatment cost. However, the incremental cost savings associated with increased patient volume depends on the hospital's current volume level and its size.

Abstract
The effects of E-4716, a novel antihistamine compound, on histamine-induced bronchoconstriction, platelet activating factor (PAF)- or antigen-induced airway hyperreactivity, eosinophil infiltration, and airway microvascular leakage were compared with those of reference drugs in guinea pigs in vivo. E-4716 (300 microg/kg, i.v. or i.p.) suppressed histamine-induced bronchoconstriction in nonsensitized anesthetized guinea pigs and effectively inhibited acetylcholine-induced bronchial hyperreactivity in nonsensitized animals 24 h after PAF aerosol exposure. E-4716 also attenuated antigen-induced acute respiratory distress and suppressed histamine-induced airways hyperreactivity in conscious sensitized animals 24 h after antigen exposure, but did not affect the increased number of eosinophils in the bronchoalveolar lavage fluid. E-4716 300 microg/kg, i.v. or 1 mg/ml by inhalation (60 breaths) inhibited both PAF- and antigen-induced airway microvascular leakage. This in vivo profile of activity, comprising antihistamine, antihyperreactivity and antiexudative effects, suggests that E-4716 is of potential therapeutic value as an antiasthma and/or antiallergic drug.

Abstract
By this investigation we want to contribute to our knowledge on the genetic characteristics of the Corsican population. The distribution of seven genetic serum protein markers (PI, TF, GC, ORM, HP, C3, PLG) was analyzed in a sample of 291 individuals coming from the central and northern areas of Corsica, i.e. from Corte and Bastia. The two samples do not show significant differences in the distribution of the genetic markers under study. The comparisons with other Mediterranean populations confirm the results of previous investigations on genetic red cell enzyme markers (Vona et al. 1995), i.e. a relatively high genetic heterogeneity of Corsicans compared with other Mediterranean populations.

Abstract
This article assesses the relative cost of providing a specific procedure, knee replacement (KR) surgery, to rural residents in rural community-based hospitals rather than in urban hospitals. Costs are predicted using regression analysis with readily available data from Health Care Financing Administration's Medicare Provider Analysis and Review. The specification incorporates the effect of referral patterns on volume and the subsequent impact on costs in the different settings. The predicted cost per case was found to be lower in rural rather than urban hospitals across all patient types. Findings indicate scale economies exist for KR surgery in both the urban and rural hospital settings. Results also suggest the total cost of a hospitalization associated with KR surgery in rural hospitals is more sensitive to changes in procedure volume than in urban hospitals, providing preliminary support for increased regionalization of KR surgery in rural hospitals. While long-term outcome measures associated with successful KR surgery (improved function, reduced pain, etc.,) are not available, mortality rates and perisurgical complication rates were not significantly different between rural patients who received KR surgery in rural hospitals and those who received KR surgery in urban hospitals. Among rural hospitals, however, complication rates were significantly correlated with procedure volume (complication rates were significantly lower in rural hospitals that performed more than nine KR surgeries a year). Our results suggest KR surgery can be delivered efficiently in rural community-based settings and support the case for regionalization of this procedure. Key words: rural hospital; hospital cost; economics of scale; regionalization.

Abstract
1. The effects of various Ca antagonists (nicardipine, nifedipine, verapamil, diltiazem, flunarizine, cinnarizine, lidoflazine and papaverine) were studied in one in vitro (inhibition of CaCl2 induced contractions in isolated rat aorta) and two in vivo tests [survival after BaCl2 in the rat and survival after arachidonic acid (AA) in the mouse]. 2. Test substances behave in different ways, thus suggesting varying mechanisms of action. 3. The three tests used are very simple and quick to perform, but taken together give a good preliminary information which allows classification of the products during the screening phase into four subgroups: dihydropyridines, verapamil, diltiazem and diphenylalkylamines.
