Abstract
PURPOSE OF REVIEW Normothermic regional perfusion (NRP) is a novel procurement technique for donation after circulatory death (DCD) in the United States. It was pioneered by cardiothoracic surgery programs and is now being applied to abdominal-only organ donors by abdominal transplant programs. Multiple technical approaches can be used for abdominal-only NRP DCD donors and this review describes these techniques. RECENT FINDINGS NRP has been associated with higher utilization of organs, particularly liver and heart grafts, from DCD donors and with better recipient outcomes. There are lower rates of delayed graft function in kidney transplant recipients and lower rates of ischemic cholangiopathy in liver transplant recipients. These benefits are driving increased interest from abdominal transplant programs in using NRP for DCD procurements. SUMMARY This paper describes the technical aspects of NRP DCD that allow for maximization of its use based on different donor and policy characteristics.

Abstract
INTRODUCTION Normothermic regional perfusion (NRP) represents an innovative technology that improves the outcomes for liver and kidney recipients of donation after circulatory determination of death (DCD) organs but protocols for abdominal-only NRP (A-NRP) DCD are lacking in the US. METHODS We describe the implementation and expansion strategies of a transplant-center-based A-NRP DCD program that has grown in volume, geographical reach, and donor acceptance parameters, presented as four eras. RESULTS In the implementation era, two donors were attempted, and one liver graft was transplanted. In the local expansion era, 33% of attempted donors resulted in transplantation and 42% of liver grafts from donors who died within the functional warm ischemic time (fWIT) limit were transplanted. In the Regional Expansion era, 25% of attempted donors resulted in transplantation and 50% of liver grafts from donors who died within the fWIT limit were transplanted. In the Donor Acceptance Expansion era, 46% of attempted donors resulted in transplantation and 72% of liver grafts from donors who died within the fWIT limit were transplanted. Eight discarded grafts demonstrated a potential opportunity for utilization. CONCLUSION The stepwise approach to building an A-NRP program described here can serve as a model for other transplant centers.

Abstract
Donation after circulatory death (DCD) donors now represent over 30% of the deceased donor pool in the United States. Compared to donation after brain death, DCD is less likely to result in transplantation. For each potential donor whose organs cannot be utilized for transplantation (ie, dry run), fees are associated with the attempted donation, which add to the overall costs of organ acquisition. To better characterize the true costs of DCD liver acquisition, we performed a cost comparison of the fees associated with organ acquisition for DCD versus donation after brain death at a single transplant institute that comprises 2 liver transplant centers. Cost, recipient, and transportation data for all cases, including fees associated with liver acquisition from July 1, 2019, to October 31, 2021, were collected. We found that the total cost of DCD liver acquisition per liver transplant was $15,029 more than that for donation after brain death donation, with 18% of the costs of the DCD transplant attributed to dry runs. Overall, the costs associated with DCD transplantation accounted for 34.5% of the total organ acquisition costs; however, DCD transplantation accounted for 30.3% of the transplantation volume. Because the expansion of DCD is essential to increasing the availability of liver grafts for transplantation, strategies need to be implemented to decrease the costs associated with dry runs, including using local recovery, transferring donors to hospitals close to transplant centers, and performing more prerecovery organ analysis. Moreover, these strategies are needed to ensure that financial disincentives to DCD procurement and utilization do not reverse the gains made by expanding the organ donor pool using machine perfusion technologies.

Abstract
The intracellular bacterial pathogen Coxiella burnetii evades the host response by secreting effector proteins that aid in establishing a replication-friendly niche. Bacterial filamentation induced by cyclic AMP (Fic) enzymes can act as effectors by covalently modifying target proteins with the posttranslational AMPylation by transferring adenosine monophosphate (AMP) from adenosine triphosphate (ATP) to a hydroxyl-containing side chain. Here we identify the gene product of C. burnetii CBU_0822, termed C. burnetii Fic 2 (CbFic2), to AMPylate host cell histone H3 at serine 10 and serine 28. We show that CbFic2 acts as a bifunctional enzyme, both capable of AMPylation as well as deAMPylation, and is regulated by the binding of DNA via a C-terminal helix-turn-helix domain. We propose that CbFic2 performs AMPylation in its monomeric state, switching to a deAMPylating dimer upon DNA binding. This study unveils reversible histone modification by a specific enzyme of a pathogenic bacterium.

Abstract
BACKGROUND Adhesive capsulitis (AC) is a painful and disabling condition with restricted range of motion (ROM) that affects 2% to 3% of the population and up to 20% of patients with diabetes. AC can be idiopathic, iatrogenic, or secondary to shoulder injuries. Some associated conditions include diabetes mellitus, thyroid disorders, dyslipidemia, stroke, prolonged immobilization, and autoimmune conditions. Management ranges from analgesics to physical therapy, local injections, hydrodilatation, and advanced surgical interventions. This study examines percutaneous coracohumeral ligament (PCHL) sectioning with the hypothesis that interruption would improve pain and ROM in patients with AC refractory to conservative management. OBJECTIVES To use sonographically guided percutaneous interruption of the CHL for the treatment of refractory AC. STUDY DESIGN A prospective, randomized, controlled, cross-over trial. SETTING Academic medical center. METHODS Patients were identified based on inclusion and exclusion criteria under the supervision of the Principal Investigator. After primary screening, research staff explained the study, risks, and benefits to the patients, and consent was obtained. Patients' pain score and shoulder ROM were assessed before and after the procedure, at one month, and one year. The Oxford Shoulder Scoring (OSS) questionnaire was also completed before the procedure and in the one-year follow-up visit.Forty patients were enrolled with refractory AC. Forty-six shoulders were treated; 6 patients underwent a bilateral procedure. Block 2:1 randomization was performed for the 2 groups (PCHL release [PCHLR] and local anesthetic CHL [LACHL]). The LACHL group received a lidocaine injection at CHL, and the PCHLR group received the CHL using a Tenex® (Tenex Health, Lake Forest, CA) needle. ROM, Numeric Rating Scale (NRS-11), and OSS were evaluated at baseline, immediate postprocedure, and long term. RESULTS Among 46 shoulders included in the study, 7 were excluded due to lost to follow-up, total shoulder replacement, and shoulder manipulation. Twenty-six were randomized to the PCHLR group and 13 to LACHL group. ROM (external rotation and abduction), pain, NRS-11 score, and OSS score were measured at baseline and long term, confirmed by a nonbiased health care personnel. There was no statistically significant difference in ROM, NRS-11, and OSS between the 2 cohorts at the baseline visit. Nine patients in LACHL group crossed over to the PCHLR arm at one month. Data analysis in the long term revealed durability of the PCHLR group with a statistically significant difference in ROM, NRS-11, and OSS. External rotation improved by double, and abduction improved by almost 30% (P value < .001). NRS-11 decreased from 8 (IQR 8, 9) at baseline to 3 (IQR 2, 7) at long term among those who received PCHLR. The baseline mean OSS in the PCHLR group increased from 7.44 to 31.86 at one-year follow-up and was statistically significant (P value < .001). LIMITATIONS This study represents a small population of patients with a CHL-related ROM deficit. Patients were not excluded for osteoarthritis or other motion-disabling shoulder conditions. We submit that the strength of the study could have been improved if the physician performing the procedure was blinded and if the patient was blinded as well to minimize operator and patient bias. CONCLUSIONS We demonstrate that our technique for PCHLR is a safe, effective, and durable procedure that improved ROM, pain, and shoulder function in our patient population when compared to the control. KEY WORDS Tenex, frozen shoulder, pain, range of motion, function, shoulder, minimally invasive, durable.

Abstract
OBJECTIVES Mental health care has been identified as a major source of mental illness stigmatization. Detailed information about these stigmatization experiences is thus needed to reduce stigma in mental health practices. The study aimed to (a) identify the most relevant stigmatizing situations in mental health care encountered by users with schizophrenia and their families; (b) characterize the relative importance of these situations in terms of frequency, experienced stigmatization, and associated suffering; and (c) identify contextual and individual factors associated with these experiences. METHOD An online survey was conducted in France among users and family members to characterize situations of stigmatization in mental health care and identify associated factors. The survey content was first developed from a participative perspective, through a focus group including users. RESULTS A total of 235 participants were included in the survey: 59 participants with schizophrenia diagnosis, 96 with other psychiatric diagnoses, and 80 family members. The results revealed 15 relevant situations with different levels of frequency, stigmatization, and suffering. Participants with a diagnosis of schizophrenia experienced more situations of stigmatization, with a higher frequency. Moreover, contextual factors were strongly associated with experienced stigmatization, including recovery-oriented practices (negatively associated) and measures without consent (positively associated). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE These situations, as well as associated contextual factors, could be targeted to reduce stigmatization and related suffering in mental health practices. Results strongly underscore the potential of recovery-oriented practice as an instrument to fight stigma in mental health care. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
In the quest of new materials that can withstand severe irradiation and mechanical extremes for advanced applications (e.g. fission & fusion reactors, space applications, etc.), design, prediction and control of advanced materials beyond current material designs become paramount. Here, through a combined experimental and simulation methodology, we design a nanocrystalline refractory high entropy alloy (RHEA) system. Compositions assessed under extreme environments and in situ electron-microscopy reveal both high thermal stability and radiation resistance. We observe grain refinement under heavy ion irradiation and resistance to dual-beam irradiation and helium implantation in the form of low defect generation and evolution, as well as no detectable grain growth. The experimental and modeling results-showing a good agreement-can be applied to design and rapidly assess other alloys subjected to extreme environmental conditions.

Abstract
The volume of abdominal organ offers received by the Baylor Simmons Transplant Institute has increased over time, resulting in a higher workload for our donor call team. To quantify the increase in organ offers, determine the characteristics of these offers, and estimate the impact on our transplant center workload, we collected center-specific organ offer data from May 2019 to July 2021 using the UNOS Center Acceptance and Refusal Evaluation Report and performed a time study that collected the number of communications and time spent on communications for organ offers made during a typical week. The total offers per month increased by 140% (270/month to 648/month), while the number of transplanted organs remained stable. In addition, the percentage of offers for organs that were never transplanted increased from 54% to 75%. In a representative week-long time study, surgeons made 505, center coordinators 590, and answering service coordinators 318 distinct communications, averaging 3, 4, and 2 communications/hour. Between November 2019 and July 2021, offer-related workload increased by an estimated 97%. These results demonstrate a sizeable inefficiency in abdominal organ allocation associated with a nonrecoverable cost to our transplant center.

Abstract
BACKGROUND Stigma is highly prejudicial to persons with schizophrenia, their families, the society and the health care system. Mental health professionals (MHP) are considered to be one of the main sources of schizophrenia stigma. OBJECTIVES The aim of the study was to identify individual and contextual factors associated with stigma in MHP in its three dimensions (stereotypes, prejudices, discrimination, Fiske, 1998). METHODS An online survey was conducted with specific measures of MHP stigma (stereotypes, prejudices and discrimination). Four categories of potential associated factors were also measured: sociodemographic characteristics, contextual characteristics (e.g., Work setting), individual characteristics (e.g., Profession, Recovery-oriented practices) and theoretical beliefs (e.g., Biological beliefs, Perceived similarities, Continuum versus Categorical beliefs). RESULTS Responses of 357 MHP were analysed. Factors that were the most strongly associated with MHP stigma were Perceived similarities, Categorical beliefs, Biological beliefs, Recovery-oriented practice and Work setting (independent practice). Conversely, Gender, Specific trainings in stigma or recovery and Cognitive aetiology beliefs showed no association with any of MHP stigma dimension. Remaining factors show associations with a weak effect size. CONCLUSIONS The survey results suggest that MHP stigma is more influenced by individual factors such as theoretical beliefs and recovery-oriented practices than contextual factors. These original results provide perspectives for reducing stigma in mental health practices.Key pointsMental health professionals (MHP) considering they share similarities with persons with schizophrenia or believing that schizophrenia is not a discrete social category but rather the extreme on a continuum between 'normal' and 'pathologic' reported less stigmatisation.MHP holding higher professional utility beliefs and using recovery-oriented practice reported fewer stereotypes, prejudice and discrimination.Other factors such as age, academic level, contact frequency, familiarity and multidisciplinary practice show associations with a weak effect size.

Abstract
Liver transplantation rates have been negatively affected by the pandemic caused by coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Current practice in the liver transplant community is to avoid utilizing SARS-CoV-2-positive donors for liver transplantation unless there is a compelling reason such as recipient illness severity. In this case, we report the use of a donor who had a positive exposure to and symptom history for COVID-19 and tested positive for SARS-CoV-2 on admission for a liver transplant recipient with primary sclerosing cholangitis and a Model of End-Stage Liver Disease score of 23 with no known COVID-19 exposures. We focus on the decision to accept this particular organ, as well as the discussion with the recipient about the unknowns of disease transmission and risk associated with this donor. The current case argues that transplant programs should begin to consider low-risk donors with positive SARS-CoV-2 testing for recipients who have the potential to benefit from liver transplantation, which may not only be those with the most severe illness.

Abstract
Background To evaluate the antimicrobial activity of the following chelating agents against Enterococcus faecalis using quantitative polymerase chain reaction (qPCR) analysis: 1% peracetic acid (PA), 1% peracetic acid with 0.1% cetrimide (PAC), and 17% ethylenediaminetetraacetic acid (EDTA) activated by passive ultrasonic irrigation (PUI) or with Easy Clean (EC), all followed by 2.5% sodium hypochlorite (NaOCl).
Material and Methods A total of 80 permanent human mandibular premolars were randomly divided into eight experimental groups according to the chemical solution and agitation protocol used: Group PA + PUI; Group PA + EC; Group PAC + PUI; PAC + EC; group EDTA + PUI; EDTA + EC, all followed by 2.5% NaOCl; and two control groups with saline solution(NaCl): NaCl + PUI and NaCl + EC. Microbial samples were collected before (S1) and after the irrigation protocol (S2). Intracanal E. faecalis reduction analysis was performed by qPCR. Intragroup analysis was performed using the Wilcoxon signed-rank test for paired data, and intergroup analysis was performed using the Wilcoxon Mann-Whitney U test for independent samples. The significance level was set at p< 0.05.
Results A significant difference was found between S1 and S2 in all groups except NaCl+ EC (p = 0.1602). Comparison between groups showed that PAC + PUI was significantly different from PA +EC (p = 0.0448).
Conclusions The activated chelating agents were effective against E. faecalis, with significant results compared to the control groups. The peracetic acid with cetrimide activated by PUI showed better results than peracetic acid with EC. Key words:Easy clean, Final irrigation protocols, Passive ultrasonic irrigation, Peracetic acid.

Abstract
Importance Acuity circles (AC) liver allocation policy was implemented to eliminate donor service area geographic boundaries from liver allocation and to decrease variability in median Model of End-stage Liver Disease (MELD) score at transplant and wait list mortality. However, the broader sharing of organs was also associated with more flights for organ procurements and higher costs associated with the increase in flights. Objective To determine whether the costs associated with liver acquisition changed after the implementation of AC allocation. Design, Setting, and Participants This single-center cost comparison study analyzed fees associated with organ acquisition before and after AC allocation implementation. The cost data were collected from a single transplant institute with 2 liver transplant centers, located 30 miles apart, in different donation service areas. Cost, recipient, and transportation data for all cases that included fees associated with liver acquisition from July 1, 2019, to October 31, 2020, were collected. Exposures Primary liver offer acceptance with associated organ procurement organization or charter flight fees. Main Outcomes and Measures Specific fees (organ acquisition, surgeon, import, and charter flight fees) and total fees per donor were collected for all accepted liver donors with at least 1 associated fee during the study period. Results Of 213 included donors, 171 were used for transplant; 90 of 171 (52.6%) were male, and the median (interquartile range) age of donors was 41.0 (30.0-52.8) years in the pre-AC period and 36.9 (24.0-48.8) years in the post-AC period. There was no significant difference in the post-AC compared with pre-AC period in median (range) MELD score (24 [8-40] vs 25 [6-40]; P = .27) or median (range) match run sequence (15 [1-3951] vs 10 [1-1138]; P = .31), nor in mean (SD) distance traveled (155.83 [157.00] vs 140.54 [144.33] nautical miles; P = .32) or percentage of donors requiring flights (58.5% [69 of 118] vs 56.8% [54 of 95]; P = .82). However, costs increased significantly in the post-AC period: total cost increased 16% per accepted donor (mean [SD] of $52 966 [13 278] vs $45 725 [9300]; P < .001) and 55% per declined donor (mean [SD] of $15 865 [3942] vs $10 217 [4853]; P < .001). Contributing factors included more than 2-fold increases in the proportions of donors incurring import fees (31.4% [37 of 118] vs 12.6% [12 of 95]; P = .002) and surgeon fees (19.5% [23 of 118] vs 9.5% [9 of 95]; P = .05), increased acquisition fees (10% increase; mean [SD] of $43 860 [3266] vs $39 980 [2236]; P < .001), and increased flight expenses (43% increase; mean [SD] of $12 904 [6066] vs $9049 [5140]; P = .002). Conclusions and Relevance The unintended consequences of implementing broader sharing without addressing organ acquisition fees to account for increased importation between organ procurement organizations must be remedied to contain costs and ensure viability of transplant programs.

Abstract
Question Were resource constraints due to the COVID-19 pandemic associated with a delay in urgent fracture surgery beyond national time-to-surgery benchmarks? Findings In this cohort pre-post study that included 3589 patients, there was no association between time to surgery and COVID-19 in either open fracture or closed femur/hip fracture cohorts. Meaning Despite concerns that the unprecedented challenges associated with the COVID-19 pandemic would delay acute management of urgent surgery, many hospital systems within the US were able to implement strategies in keeping with time-to-surgery standards for orthopedic trauma. Importance In response to the COVID-19 pandemic, many hospital systems were forced to reduce operating room capacity and reallocate resources. The outcomes of these policies on the care of injured patients and the maintenance of emergency services have not been adequately reported. Objective To evaluate whether the COVID-19 pandemic was associated with delays in urgent fracture surgery beyond national time-to-surgery benchmarks. Design, Setting, and Participants This retrospective cohort study used data collected in the Program of Randomized Trials to Evaluate Preoperative Antiseptic Skin Solutions in Orthopaedic Trauma among at 20 sites throughout the US and Canada and included patients who sustained open fractures or closed femur or hip fractures. Exposure COVID-19–era operating room restrictions were compared with pre–COVID-19 data. Main Outcomes and Measures Surgery within 24 hours after injury. Results A total of 3589 patients (mean [SD] age, 55 [25.4] years; 1913 [53.3%] male) were included in this study, 2175 pre–COVID-19 and 1414 during COVID-19. A total of 54 patients (3.1%) in the open fracture cohort and 407 patients (21.8%) in the closed hip/femur fracture cohort did not meet 24-hour time-to-surgery benchmarks. We were unable to detect any association between time to operating room and COVID-19 era in either open fracture (odds ratio [OR], 1.40; 95% CI, 0.77-2.55; P = .28) or closed femur/hip fracture (OR, 1.01; 95% CI, 0.74-1.37; P = .97) cohorts. In the closed femur/hip fracture cohort, there was no association between time to operating room and regional COVID-19 prevalence (OR, 1.07; 95% CI, 0.70-1.64; P = .76). Conclusions and Relevance In this cohort study, there was no association between meeting time-to-surgery benchmarks in either open fracture or closed femur/hip fracture during the COVID-19 pandemic compared with before the pandemic. This is counter to concerns that the unprecedented challenges associated with managing the COVID-19 pandemic would be associated with clinically significant delays in acute management of urgent surgical cases and suggests that many hospital systems within the US were able to effectively implement policies consistent with time-to-surgery standards for orthopedic trauma in the context of COVID-19–related resource constraints.

Abstract
In this study, radiation-induced precipitation of transmutation products is addressed via the development of a new solute and vacancy concentration dependant Ising model for the W-Re-Os system. This new model includes interactions between both Os and Re atoms with vacancies, thus facilitating more representative simulations of transmutation in fusion reactor components. Local solute concentration dependencies are introduced for the W-Re, W-Os and Re-Os pair interactions. The model correctly accounts for the repulsion between small clusters of vacancies and the attraction between larger clusters/voids, via the introduction of local vacancy concentration dependant interaction coefficients between pairs of atoms and vacancies. To parameterise the pair interactions between atoms and/or vacancies, the enthalpy of mixing, ΔHmix, for various configurations and solute/defect concentrations, was calculated using density functional theory, within 6 binary systems: W-Re, W-Os, Re-Os, W-vacancy, Re-vacancy and Os-vacancy. The new energy model was implemented into the SPPARKS Monte Carlo code, and successfully used to predict the formation of voids decorated with Re and Os solute atoms. Analysis suggests that there is a strong thermodynamic tendency for Os to bind to these voids with a comparatively weaker binding from Re atoms. The binding energies of various solute/vacancy clusters were calculated and showed that Re and Os solute atoms tend to stabilise small clusters of vacancies, increasing the attractive binding energy between the constituents.

Abstract
The Gudair® vaccine has been commercially available in Australia for almost two decades for the control of ovine Johne's disease, but concerns have been raised about potential discontinuation of vaccination by producers after a decline in the incidence of clinical disease. An online questionnaire was distributed to Australian sheep producers to identify the proportion of respondents discontinuing the Gudair vaccine and reasons for discontinuation. Results revealed that 88% of sheep producers surveyed have continued to vaccinate their sheep with Gudair, with continuation greater for predominantly Merino sheep flocks. Reasons for discontinuing vaccination stemmed from management, economic or health concerns. These results suggest that Gudair is still widely used by Australian sheep producers and concerns about large-scale discontinuation are unfounded. These findings have implications for ovine Johne's disease control programs in Australia.

Objective. Risk-benefit assessment for cardiac resynchronization therapy defibrillator (CRT-D) over a CRT pacemaker (CRT-P) is still a matter of debate. We aimed to identify patients with a bad outcome within one year after CRT-D implantation, and to develop a Futile CRT-D score.
Methods. Based on the administrative hospital-discharge database, all consecutive patients treated with CRT-D implantation in France between 2010 and 2019 were included. A prediction model was derived and validated for one-year all-cause death after CRT-D implantation (considered as futility) by using split-sample validation.
Results. 28,503 patients were included in the analysis (mean age 68 ± 10 years); 2,139 (7.5%) deaths were recorded in the first year. In the derivation cohort (n = 14,252), the final logistic regression model included as main predictors of futility older age, diabetes, mitral regurgitation, history of hospital stay with heart failure, history of pulmonary oedema, atrial fibrillation, renal, pulmonary, liver, or thyroid disease, denutrition and anemia. Based on Futile CRT-D score, 17% of these patients were categorized at high risk (Futile CRT-D score ≥13) and predicted futility at 17%.
Conclusion. The futility CRT-D score, established from a large nationwide cohort of patients treated with CRT-D may provide a relevant tool for optimizing healthcare decision.

Abstract
Non-contrast pelvic computed tomography (CT) can detect severe iliac artery calcifications that present technical contraindications to kidney transplantation (TCT). We screened 454 asymptomatic patients with a history of any of the following: hemodialysis >10 years, diabetes mellitus >20 years, coronary artery disease (CAD) with percutaneous or surgical interventions, carotid disease, diabetes with below-/above-knee amputations, and heart-kidney transplantation candidacy. Patients with normal dorsalis pedis and/or tibialis posterior pulses were not screened. A total of 8.4% had severe calcifications with TCT; CT determined laterality for implantation in 13.9%. No patients with the following characteristics were classified as TCT: age <40 years, hemodialysis >10 years, carotid arterial disease, prior lower extremity amputation, or heart-kidney transplantation candidacy. CAD was associated with TCT in univariate though not multivariate analysis. Limiting screening to patients >40 years, with DM >20 years, or with CAD, 9.8% had a TCT and CT determined transplant laterality in 14.2%. Screening for severe iliac artery calcifications is useful for selected kidney transplantation candidates over age 40. It can assist with laterality choice or surgeon determination of TCT. Cost and radiation exposure risks should be weighed against the morbidity risks from unnecessary surgery.

Abstract
Health risks due to NO2 exposure commonly exceed acceptable levels in modern societies. Among the measures to reduce such risks, photocatalytic materials present a promising technology. However, while the pollutant remediation of such materials has been extensively validated in laboratory studies, the performance under real world environmental exposure conditions is still subject to controversy. Indeed, a comparison of available in-situ monitoring studies manifests non-conclusive and highly scattered results regarding the photocatalytic effectiveness observed. The reasons for this behaviour must be carefully explored in order to prevent non-efficient photocatalytic applications from being put into practice on a larger scale. This paper presents a comprehensive large-scale study for assessing the photocatalytic NO2 remediation by active pavements in a street of Madrid (Spain), comprising different in-situ monitoring techniques. The discussion is enriched by relating the obtained results to those of other large-scale studies. The discrepancies between these results may be traced back to different circumstances, among them the distance between the active pavement and the pollutant concentration sampling inlet, as well as to significant site-specific and time-dependent variations of pollutant concentrations and climatic parameters. Under due consideration of these influences, for materials with relatively high initial effectiveness, it was concluded that in most such applications, the average NO2 removal effectiveness, if evaluated at a typical inlet height of Air Quality Stations (3 m), will not exceed a value of 4% (averaged over a sufficiently large number of measurement points in the area of application and a sustained amount of time, i.e. several months). When considering more realistic human exposure conditions (lower heights and daytime), it might be justified to assume somewhat higher average effectiveness.

Abstract
Although post-kidney transplant (KT) wound complications are associated with elevated body mass index (BMI), BMI is not an accurate surrogate of obesity. On the other hand, subcutaneous depth (SQD) measurement is a direct marker of truncal obesity. We examined outcomes of differing intraoperative SQD measurements in 113 KT-only recipients over 20 months. Recipients' median age was 51 years; median BMI, 28 kg/m2; and mean SQD, 2.9 cm. Patients were stratified into groups of SQD ≤2.5 cm, >2.5-5 cm, and >5 cm. An SQD of >2.5 to 5 cm correlated with a BMI of 30 kg/m2 (obesity) and an SQD >5 cm correlated with a BMI >35 kg/m2 (severe obesity). Degree of SQD was not associated with more frequent technical complications such as fascial dehiscence, lymphocele formation, renal artery thrombosis/stenosis, urine leak, or ureteral stenosis. However, an SQD >2.5 cm was a risk factor for requiring a wound vacuum-assisted closure device. There was no difference in graft or patient survival among the three SQD groups. Obesity, as measured directly by SQD, was not associated with increased technical complications or poor outcomes after KT. As expected, there was a higher incidence of wound complications in the higher SQD groups requiring intervention.

Abstract
We aim to determine the prevalence of HIV nonsuppression and factors associated with it. This is a cross-sectional multicenter study carried out in January 2016 with data of the VACH Cohort, a registry participated by 23 hospitals from most regions of Spain. The prevalence of HIV nonsuppression, defined as HIV RNA ≥200 copies/mL, is documented. The possible association of HIV nonsuppression with sociodemographic and clinical variables is assessed with a logistic regression analysis. A total of 30,843 adult patients are included; 7,358 of them (23.86%) have nonsuppressed HIV. An association is found between nonsuppression of HIV and the following variables: lower body mass index, lower age of patients in their last registered visit, lower number of visits carried out during follow-up, lower last available CD4 cell count, higher age of patients at the time of their HIV infection diagnosis, higher lowest available CD4 cell count, higher highest available HIV RNA, enrolment in the Cohort in first years of the HIV epidemic, region of Spain where the patient is attended other than Andalusia, HIV risk factor other than sexual, occurrence of death during follow-up, hepatitis C coinfection, being a smoker, pertaining to groups A1 or A2 of the CDC groups classification, and not taking antiretroviral treatment, p < .001 in all cases. HIV nonsuppression is still common with the effective antiretroviral treatment nowadays available. HIV nonsuppression is associated with HIV risk factor other than sexual, hepatitis C coinfection, and being a smoker, among other factors.

Abstract
The discovery of TREM2 as a myeloid-specific Alzheimer's disease (AD) risk gene has accelerated research into the role of microglia in AD. While TREM2 mouse models have provided critical insight, the normal and disease-associated functions of TREM2 in human microglia remain unclear. To examine this question, we profile microglia differentiated from isogenic, CRISPR-modified TREM2-knockout induced pluripotent stem cell (iPSC) lines. By combining transcriptomic and functional analyses with a chimeric AD mouse model, we find that TREM2 deletion reduces microglial survival, impairs phagocytosis of key substrates including APOE, and inhibits SDF-1α/CXCR4-mediated chemotaxis, culminating in an impaired response to beta-amyloid plaques in vivo. Single-cell sequencing of xenotransplanted human microglia further highlights a loss of disease-associated microglial (DAM) responses in human TREM2 knockout microglia that we validate by flow cytometry and immunohistochemistry. Taken together, these studies reveal both conserved and novel aspects of human TREM2 biology that likely play critical roles in the development and progression of AD.

Abstract
BACKGROUND Few women have been included in darunavir/cobicistat clinical development studies, and hardly any of them were antiretroviral experienced or treated with anything other than triple-based therapies. OBJECTIVES Our aim was to increase our knowledge about women living with HIV undergoing darunavir/cobicistat-based regimens. METHODS A multicentre (21 hospitals), retrospective study including a centrally selected random sample of HIV-1 patients starting a darunavir/cobicistat-based regimen from June 2014 to March 2017 was planned. Baseline characteristics, 24 and 48 week viral load response (<50 copies/mL), CD4+ lymphocyte count increase, time to change darunavir/cobicistat and adverse event occurrence were all compared by sex. The study was approved by each of the 21 ethics committees, and patients signed informed consent. RESULTS Out of 761 participants, 193 were women. Similar characteristics were found for both sexes, except that the women had a longer duration of HIV infection (P = 0.001), and were less frequently pre-treated with darunavir/cobicistat in their previous regimen (P = 0.02). The main reason for using a darunavir/cobicistat-based regimen was simplification, without differences by sex, while monotherapy seems to be more frequently prescribed in women than in men (P = 0.067). The main outcomes, HIV viral load response, CD4+ lymphocyte count increase at 24 or 48 weeks, occurrence of adverse events, main reasons for changing and time to the modify darunavir/cobicistat regimen, did not show differences between the sexes. CONCLUSIONS No sex disparities were found in the main study outcomes. These results support the use of a darunavir/cobicistat-based regimen in long-term pre-treated women.

Abstract
The intracellular bacterial pathogen Coxiella burnetii is the etiological agent of the emerging zoonosis Q fever. Crucial to its pathogenesis is type 4b secretion system-mediated secretion of bacterial effectors into host cells that subvert host cell membrane trafficking, leading to the biogenesis of a parasitophorous vacuole for intracellular replication. The characterization of prokaryotic serine/threonine protein kinases in bacterial pathogens is emerging as an important strategy to better understand host-pathogen interactions. In this study, we investigated CstK (for Coxiella Ser/Thr kinase), a protein kinase identified in C. burnetii by in silico analysis. We demonstrate that this putative protein kinase undergoes autophosphorylation on Thr and Tyr residues and phosphorylates a classical eukaryotic protein kinase substrate in vitro This dual Thr-Tyr kinase activity is also observed for a eukaryotic dual-specificity Tyr phosphorylation-regulated kinase class. We found that CstK is translocated during infections and localizes to Coxiella-containing vacuoles (CCVs). Moreover, a CstK-overexpressing C. burnetii strain displayed a severe CCV development phenotype, suggesting that CstK fine-tunes CCV biogenesis during the infection. Protein-protein interaction experiments identified the Rab7 GTPase-activating protein TBC1D5 as a candidate CstK-specific target, suggesting a role for this host GTPase-activating protein in Coxiella infections. Indeed, CstK co-localized with TBC1D5 in noninfected cells, and TBC1D5 was recruited to CCVs in infected cells. Accordingly, TBC1D5 depletion from infected cells significantly affected CCV development. Our results indicate that CstK functions as a bacterial effector protein that interacts with the host protein TBC1D5 during vacuole biogenesis and intracellular replication.

Abstract
Coxiella burnetii, the etiological agent of the zoonosis Q fever, replicates inside host cells within a large vacuole displaying autolysosomal characteristics. The development of this compartment is mediated by bacterial effectors, which interfere with a number of host membrane trafficking pathways. By screening a Coxiella transposon mutant library, we observed that transposon insertions in cbu0626 led to intracellular replication and vacuole biogenesis defects. Here, we demonstrate that CBU0626 is a novel member of the Coxiella vacuolar protein (Cvp) family of effector proteins, which is translocated by the Dot/Icm secretion system and localizes to vesicles with autolysosomal features as well as Coxiella-containing vacuoles (CCVs). We thus renamed this effector CvpF for Coxiella vacuolar protein F. CvpF specifically interacts with the host small GTPase RAB26, leading to the recruitment of the autophagosomal marker MAP1LC3B/LC3B (microtubule associated protein 1 light chain 3 beta) to CCVs. Importantly, cvpF::Tn mutants were highly attenuated compared to wild-type bacteria in the SCID mouse model of infection, highlighting the importance of CvpF for Coxiella virulence. These results suggest that CvpF manipulates endosomal trafficking and macroautophagy/autophagy induction for optimal C. burnetii vacuole biogenesis.

Abstract
Severe dengue was perceived as one clinical disease entity until the WHO 2009 classification stratified it into severe vascular leakage, severe bleeding, and severe organ dysfunction. The objectives of this study were to investigate the potential use of severe dengue categories as endpoints for intervention research. 271 patients with severe dengue among 1734 confirmed dengue patients were followed prospectively in this hospital-based observational study in Latin America and Asia. We compared the distribution of severe dengue categories according to gender and age (below/above 15y), and determined the relative frequency and the overlap of severe dengue categories in the same patients. In a next step, we extended the analysis to candidate moderate severity categories, based on recently suggested definitions which were adapted for our purposes. Severe vascular leakage occurred in 244 (90%), severe bleeding in 39 (14%), and severe organ dysfunction in 28 (10%) of 271 severe dengue patients. A higher frequency of severe leakage was seen in children or adolescents (<15y) compared to adults. More than 80% of the severe leakage cases, and 30-50% of the cases with severe bleeding or severe organ dysfunction, were defined as severe on the basis of that feature alone. In 136 out of 213 patients with severe leakage alone, neither moderate bleeding manifestation nor hepatic involvement was recorded. On the other hand, moderate leakage manifestations were detected in 4 out of 12 cases that were classified as severe based on bleeding alone. A major proportion of severe dengue patients exhibited clinical manifestations of severe vascular leakage only, which may constitute a useful endpoint for intervention research or pathophysiology studies. Severe bleeding and severe organ manifestation were recorded less frequently and exhibited a higher degree of overlap with severe leakage. Severe bleeding without leakage may be associated with individual predisposition or the presence of comorbidities. More detailed assessments are needed to explore this hypothesis. Candidate moderate disease endpoints were investigated and need to be further validated.
