Abstract
OBJECTIVE Calculate the efficiency of the EmERGE Pathway of Care for medically stable people living with HIV at the Hospital Clínic-IDIBAPS, Barcelona, Spain. METHODS 546 study participants were followed between 1st July 2016 and 30th October 2019 across three HIV outpatient clinics, but the virtual clinic was closed during the second year. Unit costs were calculated, linked to mean use outpatient services per patient year, one-year before and after the implementation of EmERGE. Costs were combined with primary and secondary outcomes. RESULTS Annual costs across HIV-outpatient services increased by 8%: €1073 (95%CI €999-€1157) to €1158 (95%CI €1084-€1238). Annual cost of ARVs was €7,557; total annual costs increased by 1% from €8430 (95%CI €8356-8514) to €8515 (95%CI €8441-8595). Annual cost for 433 participants managed in face-to-face (F2F) clinics decreased by 5% from €958 (95%CI 905-1018) to €904 (95%CI 863-945); participants transferred from virtual to F2F outpatient clinics (V2F) increased their annual cost by a factor of 2.2, from €115 (95%CI 94-139) to €251 (95%CI 219-290). No substantive changes were observed in primary and secondary outcomes. CONCLUSION EmERGE Pathway is an efficient and acceptable intervention. Increases in costs were caused by internal structural changes. The cost reduction observed in F2F clinics were off-set by the transfer of participants from the virtual to the F2F clinics due to the closure of the virtual clinic during the second year of the Study. Greater efficiencies are likely to be achieved by extending the use of the Pathway to other PLHIV.

Abstract
Background The purpose of this article is to summarize the opinions of the surgical oncology leaders from the Global Forum of Cancer Surgeons (GFCS) about the global impact of COVID-19 pandemic on cancer surgery. Methods A panel session (virtual) was held at the annual Society of Surgical Oncology 2021 International Conference on Surgical Cancer Care to address the impact of COVID-19 on cancer surgery globally. Following the virtual meeting, a questionnaire was sent to all the leaders to gather additional opinions. The input obtained from all the leaders was collated and analyzed to understand how cancer surgeons from across the world adapted in real-time to the impact of COVID-19 pandemic. Results The surgical oncology leaders noted that the COVID-19 pandemic led to severe disruptions in surgical cancer care across all domains of clinical care, education, and research. Several new changes/protocols associated with increased costs were implemented to deliver safe care. Leaders also noted that preexisting disparities in care were exacerbated, and the pandemic had a detrimental effect on well-being and financial status. Conclusions The COVID-19 pandemic has led to severe disruptions in surgical cancer care globally. Leaders of the GFCS opined that new strategies need to be implemented to prepare for any future catastrophic events based on the lessons learned from the current events. The GFCS will embark on developing such a roadmap to ensure that surgical cancer care is preserved in the future regardless of any catastrophic global events.

Abstract
BACKGROUND Controlled donation after circulatory death (cDCD) has expanded the donor pool for liver transplantation (LT). However, transfusion requirements and perioperative outcomes should be elucidated. The aim of this multicenter study was to assess red blood cell (RBC) transfusions, one-year graft and patient survival after LT after cDCD with normothermic regional perfusion (NRP) compared with donors after brain death (DBD). METHODS 591 LT carried out in ten centers during 2019 were reviewed. Thromboelastometry was used to manage coagulation and blood product transfusion in all centers. Normothermic regional perfusion was the standard technique for organ recovery. RESULTS 447 patients received DBD and 144 cDCD with NRP. Baseline MCF Extem was lower in the cDCD group There were no differences in the percentage of patients (63% vs. 61% p = 0.69), nor in the number of RBC units transfused (4.7 (0.2) vs 5.5 (0.4) in DBD vs cDCD, p = 0.11. Twenty-six patients (6%) died during admission for LT in the DBD group compared with 3 patients (2%) in the cDCD group (p = 0.15). To overcome the bias due to a worse coagulation profile in cDCD recipients, matched samples were compared. No differences in baseline laboratory data, or in intraoperative use of RBC or one-year outcome data were observed between DBD and cDCD recipients. CONCLUSIONS cDCD with NRP is not associated with increased RBC transfusion. No differences in graft and patient survival between cDCD and DBD were found. Donors after controlled circulatory death with NRP can increasingly be utilized with safety, improving the imbalance between organ donors and the ever-growing demand.

Abstract
Various analytical methods can be applied to concentrate, separate, and examine trace volatile organic metabolites in the breath, with the potential for noninvasive, rapid, real-time identification of various disease processes, including an array of microbial infections. Although biomarker discovery and validation in microbial infections can be technically challenging, it is an approach that has shown great promise, especially for infections that are particularly difficult to identify with standard culture and molecular amplification-based approaches. This article discusses the current state of breath analysis for the diagnosis of infectious diseases.

Abstract
BACKGROUND AND OBJECTIVE Inherited retinal dystrophies (IRDs) are a major cause of childhood blindness. Timely diagnosis requires a high level of clinical suspicion from both neurologists and ophthalmologists and is increasingly important given recent advancements in gene therapy. We focused our study on genotype-phenotype associations in very early-onset forms of retinal dystrophy, the least well characterized and most challenging diagnostic subgroup. METHODS From January 12, 2015 to March 31, 2017, we prospectively performed whole exome sequencing targeted on the phenotype of non-syndromic IRDs and phenotype characterization in a cohort of 68 children affected by very early-onset inherited retinal dystrophies, defined by the onset before five years of age. Phenotype parameters included age at onset, clinical presentation, ophthalmic evaluation, electrophysiological patterns and clinical course. RESULTS A genetically confirmed diagnosis was achieved in 50 out of 60 (83%) families. The median age at onset was 4 months (<6 m in 70%, < 2 y in 82% of the cases). Clinical presentation was associated with visual loss and nystagmus in the majority of patients. Three (CNGB3, CNGA3 and CACNA1F) out of 22 genes considered pathogenic in the cohort, accounted for 51% of all IRD's, all within the class of stationary IRDs. CONCLUSIONS This study reports on the largest cohort of very early-onset retinal dystrophies, including a description of electroretinography patterns. The electro-clinical phenotype coupled with genetic diagnosis provided additional clues for child neurologists dealing with low vision and nystagmus in infancy. A high level of clinical suspicion improves the diagnosis with important implications for the future of the affected child.

Abstract
During SARS-CoV-2 pandemic, our region (Alsace, East of France) became a Covid-19 cluster quite early in Europe. Loss of smell and taste was quickly flagged by the Ears-Nose and Throat scientific community as a potential warning signs of SARS-CoV-2 infection (1). Many patients and medical/paramedical workers with mild to moderate form of SARS-CoV-2 infection complained about their loss of sense of smell and taste to our ENT department. The aim of our study was to compare the characteristics of loss of smell and taste between patients with a clinical diagnosis of SARS-CoV-2 infection to patients with a RT-PCR diagnosis.

Abstract
The mechanisms by which protein complexes convert from functional to pathogenic are the subject of intensive research. Here, we report how functionally unfavorable protein interactions can be induced by structural fuzziness, i.e., by persisting conformational disorder in protein complexes. We show that extreme disorder in the bound state transforms the intrinsically disordered protein SERF1a from an RNA-organizing factor into a pathogenic enhancer of alpha-synuclein (aSyn) amyloid toxicity. We demonstrate that SERF1a promotes the incorporation of RNA into nucleoli and liquid-like artificial RNA-organelles by retaining an unusually high degree of conformational disorder in the RNA-bound state. However, this type of structural fuzziness also determines an undifferentiated interaction with aSyn. RNA and aSyn both bind to one identical, positively charged site of SERF1a by an analogous electrostatic binding mode, with similar binding affinities, and without any observable disorder-to-order transition. The absence of primary or secondary structure discriminants results in SERF1a being unable to select between nucleic acid and amyloidogenic protein, leading the pro-amyloid aSyn:SERF1a interaction to prevail in the cytosol under conditions of cellular stress. We suggest that fuzzy disorder in SERF1a complexes accounts for an adverse gain-of-interaction which favors toxic binding to aSyn at the expense of nontoxic RNA binding, thereby leading to a functionally distorted and pathogenic process. Thus, structural fuzziness constitutes a direct link between extreme conformational flexibility, amyloid aggregation, and the malfunctioning of RNA-associated cellular processes, three signatures of neurodegenerative proteinopathies.

Abstract
In order to establish guidelines for prescribing drugs in patients treated with plasma exchange (PE), we studied the pharmacokinetics of paracetamol (5 patients), diclofenac (4 patients) and vidarabine (3 patients) during one or several PE. Results were compared with those obtained without PE. Diclofenac and paracetamol were choosen because they presented different volume distribution and protein binding characteristics. Vidarabine was studied because we use it for the treatment of patients with polyarteritis nodosa related to hepatitis B virus. Diclofenac (100 mg) and paracetamol (1000 mg) were given 1 hour before PE. Samples were obtained 60 and 30 min before PE, every 15 min during PE and hourly for 2 hours after the end of PE. Vidarabine was given in continuous infusion, 15 mg/kg/d during the first week of treatment and 7.5 mg/kg/d during subsequent weeks. Samples were obtained before PE, 3 times during PE and every 30 min for 4 hours after the end of PE. Paracetamol, diclofenac, vidarabine and hypoxanthine arabinoside were assayed by high performance liquid chromatography. During each PE 60 ml/kg were removed and replaced by albumin. We found that 17% of diclofenac, 4.3% of paracetamol and 4.9% of vidarabine were removed during each session. Plasmapheresis clearance was 51% of plasma clearance for diclofenac, 15% for paracetamol and 10% for vidarabine. Drugs which are mainly removed during PE are those which are bound to proteins with a small distribution volume. Those drugs, such as diclofenac, must be administered after the end of each PE session. Drugs which present a large distribution volume and low protein binding can be given before the session. Vidarabine can be administered during PE without loss of effectiveness due to drug removal.

Abstract
Seven patients, 4 women and 3 men afflicted with severe progressive systemic sclerosis (PSS) were treated with Plasma Exchange after failure of different other treatment. All patients presented Raynaud phenomenon and arthritis, 6 patients presented extensive skin lesions, 5 of them digestive manifestations, 3 pulmonary fibrosis. In one case PSS was associated with polymyositis, one patient presented bilateral recurrent cornea ulcerations, (Sjögren Syndrom) and one patient numerous skin ulcerations. In 5 patients adjuvant corticosteroid therapy was given during the course of PE. In 3 patients PE must be stopped after one or two sessions because of insufficient venous access. Among the 4 other patients 8 to 20 PE were performed: the patient with cornea ulcerations became blind during the treatment, skin ulcerations and severe Raynaud phenomenon did not improved in two other patients. Benefit of PE was noted in only one patient with regressive myositis, and improvement of articular and cutaneous symptoms. Therefore, PE are not useful in most patients afflicted with PSS, they are difficult to realize in numerous patients and did not improve clinical symptoms in most cases.

Abstract
The ultrasensitive PSA assay has been recently acknowledged as a useful tool for the monitoring of patients prostatectomized for prostatic cancer. We have evaluated a commercially available ultrasensitive PSA assay (Immulite Third Generation PSA - DPC - Los Angeles CA) in comparison with the routinely used PSA (Immulite PSA - DPC - Los Angeles CA). When evaluated with different approaches, the analytical sensitivity of ultrasensitive PSA ranged between 0.0029 and 0.0038 ng/ml. The biological detection limit was 0.0098 ng/ml. Dilution of samples with low PSA levels showed a good recovery (from 88 to 113%) up to 1:128 dilution factor (final PSA levels ranging from 0.004 to 0.016 ng/ml in different samples). The assay precision was excellent in the low dose range, the highest interassay interadjustment CV among replicates being 5.84% when assaying serum samples with PSA lower than 1.0 ng/ml. Besides its role in the follow-up of prostatectomized patients, the evaluated ultrasensitive PSA could be reliably used for the detection of clinically meaningful PSA variations in the low dose range, and it could therefore be a candidate for the assessment of PSA velocity.

Abstract
BACKGROUND Syphilis is the third most commonly reported notifiable sexually transmitted infection (STI) in Canada, following chlamydia and gonorrhea, respectively. Rates of this STI have been rising rapidly in Canada since 2001. OBJECTIVE To summarize trends observed in syphilis rates for 2010 to 2015 in Canada. METHODS Laboratory-confirmed cases of infectious syphilis and early congenital syphilis were reported to the Public Health Agency of Canada by all of the Canadian provinces and territories. National infectious syphilis rates were computed, as were rates per sex, age group and province/territory. Rates of congenital syphilis were also calculated. RESULTS From 2010 to 2015, the rate of infectious syphilis in Canada increased by 85.6%, from 5.0 to 9.3 cases per 100,000 population. In 2015, a total of 3,321 cases of infectious syphilis were reported, mainly in males (93.7%), among whom the rate was 17.5 cases per 100,000 males versus 1.2 per 100,000 females. The rate also rose faster among males in 2010-2015, a 90.2% increase versus 27.8% among females. Individuals aged 20-39 years had the highest rates. Across the provinces and territories, the highest rates of infectious syphilis were in Nunavut, British Columbia and Manitoba.: The rate of congenital syphilis decreased from 2010 to 2014 (1.6 to 0.3 cases per 100,000 live births) before increasing to 1.5 cases per 100,000 live births in 2015, which corresponds to six reported cases. CONCLUSION Rates of syphilis continue to rise in Canada, especially among young men, and this is consistent with trends in the United States of America and European Union. Based on data from Canada and from these regions, the sexual behaviour of men who have sex with men (MSM) is thought to be a major risk factor for syphilis.

Abstract
Several methods for analyzing CgA using either monoclonal or polyclonal antibodies have been developed, which differ in their diagnostic performance. The present paper describes the results of a prospective multicenter study aimed at comparing the clinical value of the two most widely used commercially available CgA assay kits in patients affected by neuroendocrine tumors (NETs). Two hundred sixty-one patients from 40 different centers and 99 healthy subjects were evaluated. CgA levels were measured with two different methods, a two-step immunoradiometric assay (IRMA) and an enzyme-linked immunosorbent assay (ELISA). CgA was measured centrally by two reference laboratories, one of which used IRMA and the other ELISA, and it was measured by the participating institutions with the method routinely used by each of them. The major findings of the present study were: (i) the two assays for the determination of CgA present good diagnostic performance; (ii) both assays are robust and guarantee comparable results when applied in different settings (central vs local laboratory); (iii) the negative/positive cutoff points (87 ng/mL for IRMA and 21.3 U/L for ELISA) were established according to standardized criteria; (iv) the results obtained with the two assays in basal clinical samples of patients affected by NETs show an apparently satisfactory correlation (rs=0.843, p<0.0001). However, a possibly clinically meaningful 36% discordance rate was found. These findings support the hypothesis that the two CgA kits might provide partially different information.

Abstract
PROBLEM Most medical students use Wikipedia as an information source, yet medical schools do not train students to improve Wikipedia or use it critically. APPROACH Between November 2013 and November 2015, the authors offered fourth-year medical students a credit-bearing course to edit Wikipedia. The course was designed, delivered, and evaluated by faculty, medical librarians, and personnel from WikiProject Medicine, Wikipedia Education Foundation, and Translators Without Borders. The authors assessed the effect of the students' edits on Wikipedia's content, the effect of the course on student participants, and readership of students' chosen articles. OUTCOMES Forty-three enrolled students made 1,528 edits (average 36/student), contributing 493,994 content bytes (average 11,488/student). They added higher-quality and removed lower-quality sources for a net addition of 274 references (average 6/student). As of July 2016, none of the contributions of the first 28 students (2013, 2014) have been reversed or vandalized. Students discovered a tension between comprehensiveness and readability/translatability, yet readability of most articles increased. Students felt they improved their articles, enjoyed giving back "specifically to Wikipedia," and broadened their sense of physician responsibilities in the socially networked information era. During only the "active editing months," Wikipedia traffic statistics indicate that the 43 articles were collectively viewed 1,116,065 times. Subsequent to students' efforts, these articles have been viewed nearly 22 million times. NEXT STEPS If other schools replicate and improve on this initiative, future multi-institution studies could more accurately measure the effect of medical students on Wikipedia, and vice versa.

Abstract
In France, natural radiation accounts for most of the population exposure to ionizing radiation. The Institute for Radiological Protection and Nuclear Safety (IRSN) carries out studies to evaluate the variability of natural radioactivity over the French territory. In this framework, the present study consisted in the evaluation of uranium concentrations in bedrocks. The objective was to provide estimate of uranium content of each geological unit defined in the geological map of France (1:1,000,000). The methodology was based on the interpretation of existing geochemical data (results of whole rock sample analysis) and the knowledge of petrology and lithology of the geological units, which allowed obtaining a first estimate of the uranium content of rocks. Then, this first estimate was improved thanks to some additional information. For example, some particular or regional sedimentary rocks which could present uranium contents higher than those generally observed for these lithologies, were identified. Moreover, databases on mining provided information on the location of uranium and coal/lignite mines and thus indicated the location of particular uranium-rich rocks. The geological units, defined from their boundaries extracted from the geological map of France (1:1,000,000), were finally classified into 5 categories based on their mean uranium content. The map obtained provided useful data for establishing the geogenic radon map of France, but also for mapping countrywide exposure to terrestrial radiation and for the evaluation of background levels of natural radioactivity used for impact assessment of anthropogenic activities.

Abstract
Neurotrophins, such as brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), have been implicated in the generation and modulation of pain. To investigate whether alterations in neurotrophin levels can be detected in subjects suffering from nociceptive disorders, such as primary headaches, we determined the peripheral (platelet and plasma) levels of BDNF and NGF in patients suffering from migraine, with or without aura, or cluster headache (CH), in the interictal phase, and in healthy volunteers. All primary headaches patients studied showed significantly decreased platelet levels of BDNF (migraine vs. controls P < 0.001; CH vs. controls P < 0.01), while a selective reduction of platelet NGF was observed in migraine sufferers and not in CH patients compared with control subjects (migraine vs. controls P < 0.001). These changes were not accompanied by significant modifications of neurotrophin plasma levels. Our findings show for the first time that changes in peripheral levels of neurotrophines (BDNF and NGF) occur in patients suffering from different types of primary headaches, suggesting a potential involvement of BDNF and NGF in the pathophysiology of these disorders, and raising the possibility that differences in peripheral neurotrophins may help to distinguish migraine biologically from CH.

Abstract
The causes of hemodynamic instability in acute pancreatitis are numerous. Although pericardial effusion during pancreatitis is common, a cardiac tamponade is rarely reported. The diagnosis of compressive cardiac disorders (CDD) by echocardiography is easily reported when the patient is breathing spontaneously; it becomes difficult when the patient is assisted with positive pressure ventilation.

Abstract
Recent studies on the neurobiology of cognition have focused on the ability of the prefrontal cortex (PFC) to support processes of working memory, i.e, mnemonic processes by which information relevant for a correct response is temporarily maintained to be reevaluated or updated on a trial-by-trial basis. Of most recent interest is the role played by dopamine (DA) in spatial working memory processes of the principal sulcal region of the PFC. Although D1 DA receptors appear to modulate these mnemonic processes in monkeys, several lines of research suggest that D2 DA receptors could also be relevant to cognitive functions. Therefore, we assessed the effects of a specific D2 receptor agonist (bromocriptine) and placebo on visuospatial delayed response performance in human subjects. During delay periods of 0 or 8 sec, subjects were required to remember the spatial location of rapidly presented visual cues displayed in peripheral vision within a 360° circumference. The extent to which D2 receptor activation by bromocriptine facilitated working memory in the 8-sec delay condition relative to placebo performance was assessed. As a means of providing validation of bromocriptine's D2 receptor effect, maximum inhibition of prolactin (PRL) secretion, which is inhibited specifically by activation of D2 receptor sites, was determined. Additionally, tasks having no working memory component were administered to rule out nonspecific effects of bromocriptine on sensory, arousal, attentional, and motor factors. Results demonstrated a significant facilitatory effect of bromocriptine on spatial delayed response performance (i.e., 8-sec delay performance). Results could not be explained by nonspecific effects of bromocriptine. Thus, findings of this study suggest that spatial working memory is facilitated by D2 receptor activation. The role that DA may play in human cognitive processes is discussed within the larger theoretical framework of DA's general role in the facilitation of goal-directed behavior. In the case of cognition, DA may facilitate processes that serve to guide motivated behavior through complex environments.
