Abstract
OBJECTIVE To describe the characteristics of people indicated for directly observed treatment (DOT) in Spain, and the factors associated with unsuccessful treatment.METHODS This was a multicentre observational study based on a prospective follow-up of patients over 18 years old diagnosed with TB between 2006 and 2019 from the registry of the Programa Integrado de Investigación en Tuberculosis (PII-TB). Sociodemographic and clinical variables were collected. Adjusted odds ratios (aORs) were calculated for the indication of DOT and for having an unsuccessful treatment.RESULTS A total of 7,883 patients were included. The indication of DOT was associated with being homeless (aOR 5.93, 95% CI 3.03-11.59), inactivity status (aOR 2.55, 95% CI 2.02-3.23), alcohol consumption (aOR 1.94, 95% CI 1.51-2.48), parenteral drug use (aOR 1.77, 95% CI 1.06-2.95) and HIV diagnosis (aOR 1.96, 95% CI 1.16-3.29). Unsuccessful treatment was associated with having an HIV diagnosis (aPR 2.31, 95% CI 1.31-4.08), having a worse clinical and radiological evolution (clinical progression: APR 15.59, 95% CI 8.21-29.60; radiological progression: aPR 12.84, 95% CI 6.46-25.52), need for hospitalisation (aPR 1.73, 95% CI 1.10-2.73), unsatisfactory tolerability (aPR 2.82, 95% CI 1.49-5.29), the existence of difficulties in understanding the prescribed treatment (aPR 1.92, 95% CI 1.21-3.06), as well as worse treatment satisfaction (aPR 7.27, 95% CI 4.32-12.24).CONCLUSION The prioritisation of vulnerable populations is a key aspect to carry out the new Global Plan to End TB 2023-2030. In these groups DOT indication should be increased to ensure adherence and patient follow-up and outcomes..

Abstract
INTRODUCTION AND AIMS The outcomes of endoscopic submucosal dissection (ESD) in the esophagus have not been assessed in our country. Our primary aim was to analyze the effectiveness and safety of the technique. MATERIAL AND METHODS Analysis of the prospectively maintained national registry of ESD. We included all superficial esophageal lesions removed by ESD in 17 hospitals (20 endoscopists) between January 2016 and December 2021. Subepithelial lesions were excluded. The primary outcome was curative resection. We conducted a survival analysis and used logistic regression analysis to assess predictors of non-curative resection. RESULTS A total of 102 ESD were performed on 96 patients. The technical success rate was 100% and the percentage of en-bloc resection was 98%. The percentage of R0 and curative resection was 77.5% (n=79; 95%CI: 68%-84%) and 63.7% (n=65; 95%CI: 54%-72%), respectively. The most frequent histology was Barrett-related neoplasia (n=55 [53.9%]). The main reason for non-curative resection was deep submucosal invasion (n=25). The centers with a lower volume of ESD obtained worse results in terms of curative resection. The rate of perforation, delayed bleeding and post-procedural stenosis were 5%, 5% and 15.7%, respectively. No patient died or required surgery due to an adverse effect. After a median follow-up of 14months, 20patients (20.8%) underwent surgery and/or chemoradiotherapy, and 9 patients died (mortality 9.4%). CONCLUSIONS In Spain, esophageal ESD is curative in approximately two out of three patients, with an acceptable risk of adverse events.

Abstract
Introduction The humoral response after SARS-CoV-2 vaccination and boosters in kidney transplant recipients (KTRs) is heterogeneous and depends on immunosuppression status. There is no validated immune measurement associated with serological response in clinical practice. Multicolor flow cytometric immunophenotyping could be useful for measuring immune response. This study aimed to study B- and T-cell compartments through Standardized EuroFlow PID Orientation after SARS-CoV-2 vaccination and their association with IgG SARS-CoV-2 seropositivity status after two doses or boosters. Methods We conducted a multicenter prospective study to evaluate humoral response after SARS-CoV-2 vaccination in KTRs. Heterologous regimen: two doses of inactivated SARS-CoV-2 and two boosters of BNT162b2 mRNA (n=75). Homologous vaccination: two doses of BNT162b2 mRNA and one BNT162b2 mRNA booster (n=13). Booster doses were administrated to KTRs without taking into account their IgG SARS-CoV-2 seropositivity status. Peripheral blood samples were collected 30 days after the second dose and after the last heterologous or homologous booster. A standardized EuroFlow PID Orientation Tube (PIDOT) and a supervised automated analysis were used for immune monitoring cellular subsets after boosters. Results A total of 88 KTRs were included and divided into three groups according to the time of the first detected IgG SARS-CoV-2 seropositivity: non-responders (NRs, n=23), booster responders (BRs, n=41), and two-dose responders (2DRs, n=24). The NR group was more frequent on mycophenolate than the responder groups (NRs, 96%; BRs, 80%; 2DRs, 42%; p=0.000). Switched memory B cells in the 2DR group were higher than those in the BR and NR groups (medians of 30, 17, and 10 cells/ul, respectively; p=0.017). Additionally, the absolute count of central memory/terminal memory CD8 T cells was higher in the 2DR group than in the BR and NR groups. (166, 98, and 93 cells/ul, respectively; p=0.041). The rest of the T-cell populations studied did not show a statistical difference. Conclusion switched memory B cells and memory CD8 T-cell populations in peripheral blood were associated with the magnitude of the humoral response after SARS-CoV-2 vaccination. Boosters increased IgG anti-SARS-CoV-2 levels, CM/TM CD8 T cells, and switched MBCs in patients with seropositivity after two doses. Interestingly, no seropositivity after boosters was associated with the use of mycophenolate and a lower number of switched MBCs and CM/TM CD8 T cells in peripheral blood.

Abstract
Abstract
Study question
Are there ageing-related alterations in human sperm protein and small RNA content that can be responsible for the age-associated decline in male fertility?
Summary answer
Our results revealed a set of proteins and small RNAs, particularly miRNAs, that are altered in older men.
What is known already
Male infertility is a common health problem strongly influenced by lifestyle and environment. Advanced paternal age, in particular, has been largely associated with alterations in testicular structure and function, impaired semen parameters and DNA integrity, lower pregnancy rates and decline in offspring fitness. The decline in sperm quality with age was also associated with an increase in oxidative stress. However, only a few studies reported the deregulation of specific sperm proteins or RNAs associated with this risk factor for male infertility.
Study design, size, duration
A hundred and twenty Portuguese men from the Aveiro region were recruited between January 2019 and December 2020 at Hospital Infante D. Pedro E.P.E. (Aveiro, Portugal). All donors provided semen samples for in vitro studies with human spermatozoa. Samples were divided into four groups according to men’s age: (G1) less than 30 years; (G2) between 30 and 35 years; (G3) between 35 and 40 years and (G4) more than 40 years.
Participants/materials, setting, methods
One hundred twenty human sperm samples from volunteer donors were included in this study. Basic semen analyses were performed according to WHO’s guidelines. To avoid the possible contamination by somatic cells, density gradient sperm selection was performed. Nineteen normozoospermic human sperm samples were divided into four groups according to their age and their proteome was evaluated by quantitative proteomic analysis. The small RNA content of sixteen human sperm samples was investigated using small RNA sequencing.
Main results and the role of chance
In this study 120 men aged between 19- and 56-years old (mean age 35.2 ± 6.32 years) were recruited. Our data showed no correlation between paternal age and any seminal parameter investigated, contrary to what was previously described in other study populations. Proteomic analyses revealed 46 differentially expressed proteins (DEPs) between the four study groups (p-value< 0.05;|log2FC|=1.5). In particular, lysosomal protein LAMP1 was significantly upregulated in sperm from men younger than 30 years old compared with men with more than 35 years old. In men younger than 35 years old, cytochrome c oxidase subunit 3 (MT-CO3) and DnaJ homolog subfamily A member 1 (DNAJA1) were consistently downregulated in relation to sperm from men aged between 35 and 40 years old. Gene ontology analysis of all the deregulated sperm proteins shown that response to unfolded protein, positive regulation of mitochondrion organization, negative regulation of phosphoprotein phosphatase activity, positive regulation of apoptotic process, and spermatogenesis are common biological processes affected. Transcriptomic analysis identified 5 differentially expressed miRNAs (DEMs) between the four groups studied (p-value< 0.05), among which has-miR-374c-3p and miR-103a-3p were significantly upregulated in men younger than 35 years old compared to sperm from men aged between 35 and 40 years old.
Limitations, reasons for caution
The major limitations of this study are the relatively small sample size and the limited number of participants younger than 20 years and older than 45 years. Additionally, we cannot exclude the influence of unmeasured confounders, including lifestyle factors such as alcohol consumption, diet, exercise, and stress, in our findings.
Wider implications of the findings
Despite reproductive history and basic semen analysis being the primary steps in the assessment of male infertility, this routine examination is insufficient to explain almost 30% of the cases. The DEPs and DEMs identified could help to elucidate and/or became potential diagnostic markers for age-associated decline in human sperm quality.

Abstract
Background Antibody response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after mRNA or adenoviral vector-based vaccines is weak in kidney transplant (KT) patients. However, few studies have focused on humoral response after inactivated virus-based vaccines in KT. Here, we compare antibody response following vaccination with inactivated virus (CoronaVac®) and BNT162b2 mRNA. Methods A national multicentre cross-sectional study was conducted. The study group was composed of patients from all KT centres in Uruguay, vaccinated between 1 and 31 May 2021 (CoronaVac®, n = 245 and BNT162b2, n = 39). The control group was constituted of 82 healthy individuals. Participants had no prior confirmed coronavirus disease 2019 (COVID-19) test. Blood samples were collected between 30 and 40 days after the second dose. Serum-specific immunoglobulin G (IgG) antibodies against the receptor-binding domain (RBD) of SARS-CoV-2 Spike protein were determined using the COVID-19 IgG QUANT ELISA Kit. Results Only 29% of KT recipients showed seroconversion (36.5% BNT162b2, 27.8% inactivated virus, P = 0.248) in comparison with 100% in healthy control with either vaccine. Antibody levels against RBD were higher with BNT162b mRNA than with inactivated virus [median (interquartile range) 173 (73–554) and 29 (11–70) binding antibody units (BAU)/mL, P < 0.034] in KT and 10 times lower than healthy control [inactivated virus: 308 (209–335) and BNT162b2: 2638 (2608–3808) BAU/mL, P < 0.034]. In multivariate analysis, variables associated with negative humoral response were age, triple immunosuppression, estimated glomerular filtration rate and time post-KT. Conclusion Seroconversion was low in KT patients after vaccination with both platforms. Antibody levels against SARS-CoV-2 were lower with inactivated virus than BNT162b mRNA. These findings support the need for strategies to improve immunogenicity in KT recipients after two doses of either vaccine.

Abstract
The unfolded protein response (UPR) is a conserved and essential cellular pathway involved in protein quality control that is activated in response to several cellular stressors such as diseases states, ageing, infection and toxins. The cytosol, endoplasmic reticulum (ER) and mitochondria are continuously exposed to new proteins and in situations of aberrant protein folding; one of three lines of defence may be activated: (i) heat-shock response, (ii) mitochondrial UPR and (iii) ER UPR. These pathways lead to different signal transduction mechanisms that activate or upregulate transcription factors that, in turn, regulate genes that increase the cell's ability to correct the conformation of poorly folded proteins or, ultimately, lead to apoptosis. Despite the recent progress in understanding such biological processes, few studies have focused on the implications of the UPR in male infertility, highlighting the need for a first approach concerning the presence of these components in the male reproductive system. In testis, there is a high rate of protein synthesis, and the UPR mechanisms are well described. However, the presence of these mechanisms in spermatozoa, apparently transcriptionally inactive cells, is contentious, and it is unclear how sperm cells deal with stress. Here, we review current concepts and mechanisms of the UPR and highlight the relevance of these stress response pathways in male fertility, especially the presence and functional activation of those components in male germinal cells and spermatozoa.

Abstract
Abstract
Background
Aortic remodeling in athletes is variable among sports disciplines with more ascending aorta (Asc Ao) dilatation in endurance (EAs) as compared to power athletes (PAs). Nevertheless, the impact of this differential remodeling on the Asc Ao functional properties is not well established. The aim of this study was to assess the distensibility and stiffness of the ascending aorta in endurance and power elite athletes in order to evaluate if this aortic remodeling implies functional changes.
Methods
119 elite athletes (61 EA and 58 PA, 49% female sex, mean age: 18.7±7.1 years) underwent standardized pre-participation screening with 12 lead ECG, transthoracic echocardiography and maximum stress test. Asc Ao diameter was measured from parasternal long axis views in 2D echocardiography. The aortic distensibility index (ADi) was calculated as 2 × (systolic Asc Ao diameter − diastolic Asc Ao diameter) / (diastolic Asc Ao diameter) × (pulse pressure) (cm–2 dyn–1 10–6). Aortic stiffness (AS) index was defined as Ln (systolic blood pressure/diastolic blood pressure) / (systolic Asc Ao diameter − diastolic Asc Ao diameter)/diastolic proximal Asc Ao diameter.
Results
Globally, EA presented larger AscAO, both in absolute and indexed values, than PA (28±3.0 vs 26±3.0cm, p<0.001 and 16.4±1.5 vs 15.7±1.9cm, p<0.05, while were no differences in AS or ADi) (Figure 1A). Nevertheless, ADi in male EAs was higher than in male PAs (ADi: 4.3±1.7 vs 3.2±1.3 cm2/dyn/10–6, p<0.05) and AS was lower (AS: 4.7±1.7 vs 6.3±3.8, P<0.005) (Figure 1B and 1C). Female athletes presented higher ADi (ADi: 4.7±1.9 vs 4.0±1.6 cm, p<0.05) and a trend towards lower AS (4.8±2.9 vs 5.1±2.6, p: 0.4) than male athletes. There were no differences in AS or ADi between female EAs and PAs.
Conclusion
Male EAs showed an increased aortic distensibility with lower stiffness as compared to that observed in male PAs. This difference was not observed in female EAs and PAs, potentially due to better baseline distensibility with less room for improvement with endurance training.

Abstract
BackgroundOptimal immunosuppressive treatment for membranous nephropathy is still a matter of controversy. Current recommendations include oral cyclophosphamide combined with steroids (modified Ponticelli regimen) as first-line treatment in patients who are high risk. However, concerns about the cumulative toxicity of oral cyclophosphamide persist. In the last 30 years, a protocol based on low-dose intravenous cyclophosphamide plus steroids has been used to treat membranous nephropathy in Uruguay. We aimed to assess the efficacy of this regimen to induce clinical remission in patients with membranous nephropathy.MethodsIn this retrospective, observational cohort study, we analyzed the outcome of 55 patients with membranous nephropathy treated between 1990 and 2017 with a 6-month course of alternating steroids (months 1, 3, and 5) plus intravenous cyclophosphamide (single dose of 15 mg/kg on the first day of months 2, 4, and 6).ResultsAt 24 months, 39 (71%) patients achieved clinical response with complete remission observed in 23 patients (42%) and partial remission in 16 (29%). Median time to achieve partial and complete remission was 5.9 and 11.5 months, respectively. Absence of response was observed in 16 patients (29%), five of whom started chronic RRT after a median follow-up of 3.5 years. Clinical relapse occurred in nine of 33 (27%) patients at a median of 34 months after treatment discontinuation.ConclusionsReplacement of oral cyclophosphamide with a single intravenous pulse on months 2, 4, and 6 of the modified Ponticelli regimen can be an effective and safe alternative for treatment of membranous nephropathy.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/K360/2020_09_24_KID0002802020.mp3

Abstract
BACKGROUND AND AIMS The Endoscopic Resection Group of the Spanish Society of Endoscopy (GSEED-RE) model and the Australian Colonic Endoscopic Resection (ACER) model were proposed to predict delayed bleeding (DB) after EMR of large superficial colorectal lesions, but neither has been validated. We validated and updated these models. METHODS A multicenter cohort study was performed in patients with nonpedunculated lesions ≥20 mm removed by EMR. We assessed the discrimination and calibration of the GSEED-RE and ACER models. Difficulty performing EMR was subjectively categorized as low, medium, or high. We created a new model, including factors associated with DB in 3 cohort studies. RESULTS DB occurred in 45 of 1034 EMRs (4.5%); it was associated with proximal location (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.31-6.16), antiplatelet agents (OR, 2.51; 95% CI, .99-6.34) or anticoagulants (OR, 4.54; 95% CI, 2.14-9.63), difficulty of EMR (OR, 3.23; 95% CI, 1.41-7.40), and comorbidity (OR, 2.11; 95% CI, .99-4.47). The GSEED-RE and ACER models did not accurately predict DB. Re-estimation and recalibration yielded acceptable results (GSEED-RE area under the curve [AUC], .64 [95% CI, .54-.74]; ACER AUC, .65 [95% CI, .57-.73]). We used lesion size, proximal location, comorbidity, and antiplatelet or anticoagulant therapy to generate a new model, the GSEED-RE2, which achieved higher AUC values (.69-.73; 95% CI, .59-.80) and exhibited lower susceptibility to changes among datasets. CONCLUSIONS The updated GSEED-RE and ACER models achieved acceptable prediction levels of DB. The GSEED-RE2 model may achieve better prediction results and could be used to guide the management of patients after validation by other external groups.

Abstract
BACKGROUND Only 40-60% of patients with generalized anxiety disorder experience long-lasting improvement with gold standard psychosocial interventions. Identifying neurobehavioral factors that predict treatment success might provide specific targets for more individualized interventions, fostering more optimal outcomes and bringing us closer to the goal of "personalized medicine." Research suggests that reward and threat processing (approach/avoidance behavior) and cognitive control may be important for understanding anxiety and comorbid depressive disorders and may have relevance to treatment outcomes. This study was designed to determine whether approach-avoidance behaviors and associated neural responses moderate treatment response to exposure-based versus behavioral activation therapy for generalized anxiety disorder. METHODS/DESIGN We are conducting a randomized controlled trial involving two 10-week group-based interventions: exposure-based therapy or behavioral activation therapy. These interventions focus on specific and unique aspects of threat and reward processing, respectively. Prior to and after treatment, participants are interviewed and undergo behavioral, biomarker, and neuroimaging assessments, with a focus on approach and avoidance processing and decision-making. Primary analyses will use mixed models to examine whether hypothesized approach, avoidance, and conflict arbitration behaviors and associated neural responses at baseline moderate symptom change with treatment, as assessed using the Generalized Anxiety Disorder-7 item scale. Exploratory analyses will examine additional potential treatment moderators and use data reduction and machine learning methods. DISCUSSION This protocol provides a framework for how studies may be designed to move the field toward neuroscience-informed and personalized psychosocial treatments. The results of this trial will have implications for approach-avoidance processing in generalized anxiety disorder, relationships between levels of analysis (i.e., behavioral, neural), and predictors of behavioral therapy outcome. TRIAL REGISTRATION The study was retrospectively registered within 21 days of first participant enrollment in accordance with FDAAA 801 with ClinicalTrials.gov, NCT02807480. Registered on June 21, 2016, before results.

Abstract
ABSTRACT The objective of the study was to determine whether or not there is a correlation between thermoresistance tests (TT) after semen thawing and pregnancy rate (PR) after fixed-time artificial insemination (FTAI). Four different TT were performed on ten samples used for AI; a rapid test (RTT) (30min / 46°C) and three slow tests (STT): STT1 (60min/38°C), STT2 (180min/38°C), and STT3 (300min/38°C). Two hundred and fifteen multiparous crossbred cows were submitted to FTAI under the following protocol: on day zero (d0) the animals received a P4 device +EB; on d7 PGF2α; on d8 P4 was removed and eCG+EC were administered; IATF was performed on d10. Three gestational diagnoses (G D) were performed on d40, d70 and d120. The mean sperm motility (%) in RTT and STTs were 19.84±6.13, 28.55±10.48, 17.62±5.87 and 8.63±3.46, respectively, and TP in the three DG 61.86%, 57.67%, and 55.81%, respectively. Through Person test a significant negative correlation (P< 0.05) was found between STT2 and PR at 60 days (r= -0.644) and between STT3 and all TPs (r= -0.774, -0.752, 0.748). It was concluded that TT parameters are not able to determine correlation between semen quality and TP.

Abstract
BACKGROUND & AIMS It is not clear whether closure of mucosal defects with clips after colonic endoscopic mucosal resection (EMR) prevents delayed bleeding, although it seems to have no protective effects when risk is low. We performed a randomized trial to evaluate the efficacy of complete clip closure of large (≥2 cm) nonpedunculated colorectal lesions after EMR in patients with an estimated average or high risk of delayed bleeding. METHODS We performed a single-blind trial at 11 hospitals in Spain from May 2016 through June 2018, including 235 consecutive patients who underwent EMR for large nonpedunculated colorectal lesions with an average or high risk of delayed bleeding (based on Spanish Endoscopy Society Endoscopic Resection Group score). Participants were randomly assigned to groups that received closure of the scar with 11-mm through-the-scope clips (treated, n = 119) or no clip (control, n = 116). The primary outcome was proportion of patients in each group with delayed bleeding, defined as evident hematochezia that required medical intervention within 15 days after colonoscopy. RESULTS In the clip group, complete closure was achieved in 68 (57%) cases, with partial closure in 33 (28%) cases and failure to close in 18 (15%) cases. Delayed bleeding occurred in 14 (12.1%) patients in the control group and in 6 (5%) patients in the clip group (absolute risk difference, reduction of 7% in the clip group; 95% confidence interval, -14.7% to 0.3%). After completion of the clip closure, there was only 1 (1.5%) case of delayed bleeding (absolute risk difference, reduction of 10.6%; 95% confidence interval, -4.3% to 17.9%). CONCLUSIONS In a randomized trial of patients with large nonpedunculated colorectal lesions undergoing EMR, we found that clip closure of mucosal defects in patients with a risk of bleeding can be a challenge, but also reduces delayed bleeding. Prevention of delayed bleeding required complete clip closure. ClinicalTrials.gov ID: NCT02765022.

Abstract
Few studies have examined the relationship between non-immunological factors and glomerular filtration rate (GFR) decline in kidney transplant. Correcting these factors in native kidneys slows the progression of chronic kidney disease. The aim of this study was to analyze the association between the control of non-immunological factors and the annual decline of GFR. METHODS A single-center, retrospective study was performed. We included 128 patients who received kidney transplants between 2000 and 2015, with at least 1-year post-transplant follow-up. Clinical records were reviewed. GFR was estimated by CKD-EPI. Three groups were defined according to the annual change in eGFR (ΔGFR 2016-1015): non-progressors (> -1 mL/min/1.73 m2), slow progressors (> -1 and < -5 mL/min/1.73 m2), and fast progressors (< -5 mL/min/1.73 m2). Percentage of achievement of KDIGO target was also analyzed. RESULTS The mean GFR was 62.5 mL/min/1.73 m2. Glomerulonephritis was the most common cause of kidney failure (36%). When the fast progressor group was compared with the non-progressor group, they differed significantly in age-patients were younger (40 ± 12.3 vs 45 ± 13.1 years)-post-transplant body mass index (27.4 ± 5.6 vs 25.2 x ± 5.9 kg/m2), and serum uric acid, which was significantly higher (6.4 ± 1.7 vs 5.5 ± 1.58 mg/dL). There were no differences between the groups with regard to blood pressure, dyslipidemia, proteinuria, or venous bicarbonate. Target systolic blood pressure was achieved by 45% of patients. Biopsy-proven acute rejection was higher in the fast progression group, although this was not statistically significant (13 [24.5%] vs 8 [13.1%]). CONCLUSIONS High body mass index was associated with a faster decline in glomerular filtration rate in this study. Target blood pressure <140/90 mm Hg was achieved in less than 50% of cases.

Abstract
Although sleep-dependent consolidation and its neurochemical underpinnings have been strongly researched, less is known about how consolidation during sleep affects subsequent learning. Since sleep enhances memory, it can be expected to pro-actively interfere with learning after sleep, in particular of similar materials. This pro-active interference should be enhanced by substances that benefit consolidation during sleep, such as D-cycloserine. We tested this hypothesis in two groups (Sleep, Wake) of young healthy participants receiving on one occasion D-cycloserine (175 mg) and on another occasion placebo, according to a double-blind balanced crossover design. Treatment was administered after participants had learned a set of word pairs (A-B list) and before nocturnal retention periods of sleep vs. wakefulness. After D-cycloserine blood plasma levels had dropped to negligible amounts, i.e., the next day in the evening, participants learned, in three sequential runs, new sets of word pairs. One list-to enhance interference-consisted of the same cue words as the original set paired with a new target word (A-C list) and the other of completely new cue words (D-E set). Unexpectedly, during post-retention learning the A-C interference list was generally better learned than the completely new D-E list, which suggests that consolidation of previously encoded similar material enhances memory integration rather than pro-active interference. Consistent with this view, new learning of word pairs was better after sleep than wakefulness. Similarly, D-cycloserine generally enhanced learning of new word pairs, compared to placebo. This effect being independent of sleep or wakefulness, leads us to speculate that D-cycloserine, in addition to enhancing sleep-dependent consolidation, might mediate a time-dependent process of active forgetting.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
One of the main mechanisms blocking translation after stress situations is mediated by phosphorylation of the α-subunit of the eukaryotic initiation factor 2 (eIF2), performed in Arabidopsis by the protein kinase GCN2 which interacts and is activated by ILITHYIA(ILA). ILA is involved in plant immunity and its mutant lines present phenotypes not shared by the gcn2 mutants. The functional link between these two genes remains elusive in plants. In this study, we show that, although both ILA and GCN2 genes are necessary to mediate eIF2α phosphorylation upon treatments with the aromatic amino acid biosynthesis inhibitor glyphosate, their mutants develop distinct root and chloroplast phenotypes. Electron microscopy experiments reveal that ila mutants, but not gcn2, are affected in chloroplast biogenesis, explaining the macroscopic phenotype previously observed for these mutants. ila3 mutants present a complex transcriptional reprogramming affecting defense responses, photosynthesis and protein folding, among others. Double mutant analyses suggest that ILA has a distinct function which is independent of GCN2 and eIF2α phosphorylation. These results suggest that these two genes may have common but also distinct functions in Arabidopsis.

Abstract
We demonstrate polarization-controlled switching of the orbital angular momentum (OAM) transfer in nonlinear wave mixing. By adjusting the input beam geometry, we are able to produce a three-channel orbital OAM, with arbitrary topological charges simultaneously generated and spatially resolved in the second-harmonic wavelength. The use of path and polarization degrees of freedom allows nearly perfect optical switching between different OAM operations. These results are supported by a theoretical model showing very good agreement with the experiments.

Abstract
The serrated pathway has been shown to be an alternative colorectal carcinogenetic route potentially accounting for up to one third of all CRCs. Serrated lesions, particularly SSPs, have been a focus of research during the past few years. They have well-established histological and molecular characteristics that account for their potential carcinogenetic risk through the accumulation BRAF, KRAS and methylator profile (CpG) mutations. Their endoscopic identification and resection represent a challenge because of their specific characteristics, and the need for an adequate specimen for histological diagnosis. Knowledge of these lesions is key, as is the adoption of established criteria for their endoscopic description and histological diagnosis. SPS is the maximum expression of involvement by serrated lesions, is associated with increased risk for CRC, and requires attentive endoscopic follow-up, as well as family screening. While the exact etiopathogenic mechanism remains unknown, current research will likely provide us with appropriate answers in the not too distant future.

Abstract
BACKGROUND & AIMS After endoscopic mucosal resection (EMR) of colorectal lesions, delayed bleeding is the most common serious complication, but there are no guidelines for its prevention. We aimed to identify risk factors associated with delayed bleeding that required medical attention after discharge until day 15 and develop a scoring system to identify patients at risk. METHODS We performed a prospective study of 1214 consecutive patients with nonpedunculated colorectal lesions 20 mm or larger treated by EMR (n = 1255) at 23 hospitals in Spain, from February 2013 through February 2015. Patients were examined 15 days after the procedure, and medical data were collected. We used the data to create a delayed bleeding scoring system, and assigned a weight to each risk factor based on the β parameter from multivariate logistic regression analysis. Patients were classified as being at low, average, or high risk for delayed bleeding. RESULTS Delayed bleeding occurred in 46 cases (3.7%, 95% confidence interval, 2.7%-4.9%). In multivariate analysis, factors associated with delayed bleeding included age ≥75 years (odds ratio [OR], 2.36; P < .01), American Society of Anesthesiologist classification scores of III or IV (OR, 1.90; P ≤ .05), aspirin use during EMR (OR, 3.16; P < .05), right-sided lesions (OR, 4.86; P < .01), lesion size ≥40 mm (OR, 1.91; P ≤ .05), and a mucosal gap not closed by hemoclips (OR, 3.63; P ≤ .01). We developed a risk scoring system based on these 6 variables that assigned patients to the low-risk (score, 0-3), average-risk (score, 4-7), or high-risk (score, 8-10) categories with a receiver operating characteristic curve of 0.77 (95% confidence interval, 0.70-0.83). In these groups, the probabilities of delayed bleeding were 0.6%, 5.5%, and 40%, respectively. CONCLUSIONS The risk of delayed bleeding after EMR of large colorectal lesions is 3.7%. We developed a risk scoring system based on 6 factors that determined the risk for delayed bleeding (receiver operating characteristic curve, 0.77). The factors most strongly associated with delayed bleeding were right-sided lesions, aspirin use, and mucosal defects not closed by hemoclips. Patients considered to be high risk (score, 8-10) had a 40% probability of delayed bleeding.

Abstract
Bee products (BP) have been used for centuries as a diet complement with claimed curative properties. The aim of this study was to determine whether oral administration of BP prevented behavioral, histological, and biochemical alterations, caused by pentylenetetrazole (PTZ)-induced kindling in rats. Male Wistar rats were employed to evaluate seizure latency, number and duration, performance in the open field test, histological alterations and mortality following BP administration. Oral administration of BP at two doses, 30 and 60 mg/kg/day, significantly lengthened latency of both clonic and tonic PTZ-induced seizures, decreased the duration and frequency of seizures and reduced mortality. In the Open Field test, BP treated groups showed increases in the number of crossed squares and rearing counts, and on optimal dose, decreases in fecal boli. Histological analysis showed in PTZ (50 and 80 mg/kg) kindling rats, lungs with inflammatory peribronchiolar, and perialveolar infiltrates. In the liver, mild losses of trabeculae, multi-vesiculated hepatocytes (steatosis) and inflammatory infiltrates in hepatic parenchyma were observed. Interestingly, in the heart, fibers were markedly separated. In testis, stratified epithelium of seminal tubules lost its normal structure, tubules had epithelium loss, spermatids were absent, and spermatogonia and Leydig cells diminished. In PTZ kindling rats treated with BP, the lungs had no inflammatory infiltrates, although the heart showed some inflammatory infiltrates. Remaining structures had normal characteristics. These results, suggest that BP can protect rats from effects of PTZ-induced kindling.

Abstract
UNLABELLED Hyperargininaemia is a rare inborn error of metabolism due to a defect in the final step of the urea cycle. Infantile onset is the most common presentation with recurrent vomiting and psychomotor delay associated with spastic paraparesis; chronic hyperammonaemia is often overlooked. Neonatal and early-onset presentations are very uncommon and their clinical course not well-described. We report on a 3-week-old hyperargininaemic girl who presented with neurological deterioration associated with liver failure and 47-day ammonia intoxication before diagnosis could be made and treatment started. Despite appropriate but delayed treatment, our patient exhibited severe psychomotor delay at age 1 year. CONCLUSION Early identification and management of this rare but potentially treatable affection is crucial as delayed management may result in poor neurological outcome.

Abstract
e20645 Background: The Comprehensive Geriatric Assessment (CGA) is a key component of the treatment approach for older cancer patients, but it is time consuming. In this study, we have evaluated the validity of a brief frailty screening tool, the Barber test (BT), for identifying disability in older patients with early breast cancer (BC) in the University General Hospital in Elche. Methods: Between January 2007 and December 2007, a total of 41 patients older than 65 years who were actively receiving chemotherapy for early BC, were enrolled in our study. Eligible patients were screened with the Barber test and completed a standardized CGA (Activities of Daily Living measured by Barthel Scale, Instrumental Activities of Daily Living measured by Lawton-Brody Scale, cognitive evaluation measured by Pfeiffer Test, comorbidity (Charlson´s index), risk of malnutrition (Nutritive Initiative Screening), and ECOG). The validity of the BT in this population was assessed by comparing the BT results with results from a simultaneous CGA. A receiver operating characteristic (ROC) analysis was employed. The ROC evaluated the BT as a screening measure for impairment compared with the CGA (using the definition of impairment on the CGA as deficits on ≥2 individual tests within the battery, and on the BT as a score >0). The area under the ROC curve (AUC) was calculated to reflect the predictive value of the BT for identifying impairment. Results: Forty-one women were recruited. Median age was 72.88 years (range 65.03 to 85.46). 30 patients (73.2%) were older than 70 years. 36.6% were dependent in Barthel Scale, and 46,3% were dependent in Lawton-Brody Scale. 19,5% had cognitive impairment. The Barber test was moderate predictive for identifying impairment compared with the CGA, with an AUC of 0.730 (standard error, 0.081; 95% confidence interval for detecting asymptomatic normals, 0.571–0.889); p=0.012). Conclusions: Functional impairments are prevalent among older patients with early BC who receive adjuvant chemotherapy treatment. The current results indicate that the brief Barber test performed nearly as well as a conventional CGA in detecting geriatric impairment in this population. No significant financial relationships to disclose.

Abstract
Premature cardiovascular disease (CVD) begins in youth--a crucial period when modification of the disease may have the greatest impact. Failure to diagnose preclinical CVD at this stage misses a major opportunity to prevent the long-term consequences of this disease. An array of surrogate vascular markers (SVMs) are now available that can determine the extent of preclinical vascular injury in the pediatric population. These SVMs include flow-mediated vasodilatation, carotid intima media thickness, arterial stiffness, and biomarkers including high sensitivity C-reactive protein, cell adhesion molecules and methylarginines. We believe that the use of these SVMs will help to develop a better understanding of early pathological vascular changes in youth, facilitate earlier diagnosis of preclinical atherosclerosis and provide an objective measure of the vascular effects of any therapeutic intervention aimed at risk factor modification. Ultimately, our future health will depend on carefully balancing the benefits of early diagnosis and treatment in high-risk youth with the long-term risk of CVD. The application of SVMs in the pediatric population will help us achieve this balance.

Abstract
Wiedemann-Beckwith syndrome (WBS) is a syndrome of excessive growing with a high predisposition to developing embryologic tumours within the first years of life. This risk is evaluated between 7.5 and 10%; it varies with the mechanisms of mutations involved. These take place in two distinct domains of 11p15, which are under parental printing. Emerging techniques of cytogenetic and molecular biology now have shown correlations between genotypes and phenotypes, and can identify the 30% of WBS who are especially at risk of developing tumours. A specific follow-up, integrating the specificity of developing tumours of each 11p15 mutations involved, is now proposed to patients with WBS.

Abstract
Macrophages play a crucial role in respiratory viral infections. However, the mechanisms by which these cells are recruited locally are not fully understood. The current authors studied the role of the chemokines monocyte chemotactic protein (MCP)-1, -2, -3 and -4 on monocyte/macrophage recruitment during respiratory viral infections. Levels of these chemokines were investigated in nasal aspirates from 6-12-yr-old children suffering from respiratory viral infections, caused by rhinoviruses, influenza viruses, parainfluenza viruses, adenoviruses and respiratory syncytial virus. MCP-3 and -4 were significantly higher in samples derived from virus-infected children compared with samples from the same children when they had been asymptomatic. Concentrations of both chemokines were found to significantly correlate with the number of recruited nasal macrophages. Chemotaxis assays showed that purified MCP-3 and -4 from nasal aspirates showed biological activity in vitro. There were no significant differences in MCP-1 and -2 levels between both groups. The present data indicates that monocyte chemotactic protein-3 and -4 may have an important role in macrophage recruitment in children with proven upper respiratory viral infections. These chemokines could be potential targets for therapeutic intervention in respiratory viral infections.

Abstract
Hepatitis B virus (HBV) is responsible for a worldwide mortality of 1 million people each year. It constitutes a major public health problem, especially in highly endemic zones, where it concerns the youngest children, primarily by a mother to child transmission, with a strong risk of chronic hepatitis infection and hepatocellular carcinoma. Immunisation of children versus HBV is known to be efficient and safe. In Mayotte, a French overseas territory in Indian Ocean, immunisation versus HBV has been introduced since 1993 in the vaccine schedule, starting at day 1 of life. We report hereby the local experience and practice on HBV infection, state of vaccine coverage, and difficulties met with this major public health issue.

Abstract
Sensory nerve grafts are the "gold standard" for inducing neurological recovery in peripheral nerves with a gap. However, the effectiveness of sensory nerve grafts is variable, generally not leading to complete sensory and motor recovery, with good recovery limited to gaps shorter than 2 cm, and the extent of recovery decreasing with increasing graft length. An alternative technique using a conduit filled with pure fibrin to bridge a nerve gap leads to only limited neurological recovery. We tested the effectiveness of a novel nerve repair technique in which a 5-cm long radial nerve gap was repaired using two sural nerve graft surrounded by a collage tube filled with pure fibrin. By 1 1/2 years post surgery, the patient recovered complete sensory and motor function. In conclusion, this study suggests that the combination of pure fibrin surrounding sural nerve grafts is responsible for inducing the extensive neurological recovery induced by either pure fibrin or sural grafts alone. This technique is presently being tested in a clinical trial.

Abstract
Nontuberculous mycobacterial infections are rare in immunocompetent children, and usually present as adenitis. We report a case of a 6-year-old girl with a multifocal chronic osteomyelitis and pulmonary localisation due to Mycobacterium intracellulare associated with an autosomal dominant mutation of interferon gamma receptor 1 gene (INFGR1) leading to a syndrome of mendelian predisposition to mycobacteria infections by partial deficiency of intracellular signalisation of gamma interferon. This child has been cured with anti-mycobacteria drugs and gamma interferon. This report focus on the importance of looking for a susceptibility of the host to infectious diseases, which can lead to a specific treatment. As far as we know, this is the first case described in a tropical area.

Abstract
PURPOSE Since oxidative injury is implicated in radiation-induced tissue damage to the lung, we studied systemically administered polyethylene glycol (PEGylated) antioxidant enzymes (AOEs) as pulmonary radioprotectors in mice. METHODS AND MATERIALS C57/bl6 Mice received 13.5 Gy single-dose irradiation to the thorax. One cohort also received 100 microg of a 1:1 mixture of PEG-AOEs {PEG-catalase and PEG-superoxide dismutase (SOD)} intravenously, pre-irradiation and subgroups were evaluated at variable time-points for inflammation and fibrosis. Potential for AOE tumor protection was studied by thoracic irradiation of mice with Lewis lung carcinoma. RESULTS At 48 h post-irradiation, control irradiated mice had marked elevations of tissue p21, Bax and TGF-beta1 in lungs, not seen in irradiated, PEG-AOE-treated mice. TUNEL staining of lung sections was performed at just one time-point (24 h post-irradiation) and revealed a decrease in apoptotic cells with AOE treatment. At four months post-irradiation, these mice had significantly increased pulmonary fibrosis as measured by hydroxyproline content. Mice treated with PEG-AOE prior to irradiation had 4-month hydroxyproline levels that were similar to that of unirradiated controls (p = 0.28). This corresponded to less pulmonary fibrosis as visualized histologically when compared with mice irradiated without AOEs. PEG-AOEs did not prevent post-irradiation pulmonary inflammation or lung cancer response to irradiation. CONCLUSIONS A mixture of PEG-SOD and PEG-CAT successfully diminished radiation pulmonary fibrosis in mice. There was also a corresponding effect on several early biomarkers of lung injury and decreased apoptosis. There were no significant effects on acute pneumonitis or tumor protection.
