Abstract
Here, we studied the interaction between the food colorant tartrazine (TZ) and double stranded DNA (dsDNA), using spectroscopic, electrochemical, and computational methods such as QM/MM combined with TD-DFT. Despite the UV-vis spectroscopy is widely used to study the interaction between molecules, for the case of TZ there are discrepancies in the analyses presented in the literature available, presenting both hyperchromic and hypochromic effects and consequently different rationalizations for their results. Herein we propose the combination of UV-vis experiments with the design of high-level computational models capable of reproducing the experimental behavior to finally define the proper binding mode at the molecular scale together with the rationalization of the experimental optical response due to the complex formation. To complement the UV-vis experiments, we propose the use of electrochemical measurements, to support the results obtained through UV-vis spectroscopy, as it has been successfully used for the determination of interaction modes between small molecules and biomolecules in any condition. Our UV-vis spectroscopy experiments showed only a hypochromic effect of the absorption spectra of TZ after interaction with DNA, indicative of TZ being deeply buried in the DNA structure. The effect of ionic strength in the experimental procedures led to the dissociation of TZ, thus indicating that the interaction mode was groove binding. On the other hand, the electrochemical studies showed an irreversible reduction peak of TZ, which after the interaction with DNA exhibited a positive shift in potential that can be attributed to groove binding. The binding constant for TZ-DNA was calculated as 4.45x104M-1 (UV-vis) and 5.75x104M-1 (electrochemistry), in line with other groove binder azo dyes. Finally, through the QM/MM calculations we found that the minor-groove binding mode interacting in zones rich in adenine and thymine was the model best suited to reproduce the experimental UV-vis response.

Abstract
Abstract
Background
There is scarce evidence on fourth doses of SARS-CoV-2 vaccines in chronic kidney disease (CKD) patients. We have evaluated the humoral response and effectivity of the fourth dose in the CKD spectrum: non-dialysis CKD (ND-CKD), hemodialysis (HD), peritoneal dialysis (PD) and kidney transplant (KT) recipients.
Methods
This is a prespecified analysis of the prospective, observational, multicentric SENCOVAC study. In patients with CKD who had received a complete initial vaccination and one or two boosters and had anti-Spike antibody determinations 6 and 12 months after the initial vaccination, we analyzed factors associated to persistent negative humoral response and to higher anti-Spike antibody titers as well as the efficacy of vaccination on COVID-19 severity.
Results
Of 2186 patients (18% KT, 8% PD, 69% HD and 5% ND-CKD), 30% had received a fourth dose. The fourth dose increased anti-Spike antibody titers in HD (P = 0.001) and ND-CKD (P = 0.014) patients and seroconverted 72% of previously negative patients. Higher anti-Spike antibody titers at 12 months were independently associated to repeated exposure to antigen (fourth dose, previous breakthrough infections), previous anti-Spike antibody titers and not being a KT. Breakthrough COVID-19 was registered in 137 (6%) patients, of whom 5% required admission. Admitted patients had prior titers below 620 UI/ml and median values were lower (P = 0.020) than in non-admitted patients.
Conclusions
A fourth vaccine dose increased anti-Spike antibody titers or seroconverted many CKD patients, but those with the highest need for a vaccine booster (i.e. those with lower pre-booster antibody titers or KT recipients) derived the least benefit in terms of antibody titers. Admission for breakthrough COVID-19 was associated with low anti-Spike antibody titers.

Abstract
Abstract
Aim
This study aims to examine the effects of low-quality employment trajectories on severe common mental disorders (CMD) according to Swedish and foreign background.
Methods
This is a longitudinal study based on Swedish population registries (N = 2,703,687). Low- and high-quality employment trajectories observed across five years (2005-2009) are the exposure with severe CMD as outcome (2010-2017). Adjusted hazard ratios (HR) were calculated using Cox regression stratified according to background (first-generation (i) EU migrants, (ii) non-EU migrants, (iii) second-generation migrants, (iv) Swedish-born with Swedish background) and sex. The reference group were Swedish-born with Swedish background in a Constant high-quality employment trajectory.
Results
Second-generation migrants had an increased risk of CMD compared to Swedish-born with Swedish background when following low-quality employment trajectories (e.g., male in Constant low-quality HR: 1.53, 95% CI: 1.41-1.68). Female migrant workers, especially first-generation from non-Western countries in low-quality employment trajectories (e.g., Constant low-quality HR: 1.65, 95% CI:1.46 - 1.87), had a higher risk of CMD compared to female Swedish-born with Swedish background. The confidence interval for CMD risk showed little differences between migrant groups (1st and 2nd generation) compared to the reference group.
Conclusions
Low-quality employment trajectories appear to be determinants of risk for CMD, having a differential impact according to background of origin and sex. We observe a higher risk for severe CMD across migrant groups, especially second-generation migrants, compared to Swedish-born with Swedish background. Further qualitative research is recommended to understand the mechanism behind the differential mental health impact of low-quality employment trajectories according to foreign background.
Key messages
• First and second-generation migrants in low quality employment have higher risk of severe common mental disorders compared to Swedish born with Swedish background workers in low quality employment.
• Policies targeting working conditions in low-quality employment and promoting workers mental well-being are essential to reduce this higher risk for developing CMD, especially for migrant populations.

Abstract
BackgroundTolvaptan (TV) is the first vasopressin-receptor antagonist approved for the treatment of autosomal dominant polycystic kidney disease (ADPKD). No publications report TV experience in real clinical practice during the first year of treatment.MethodsA prospective study of an initial cohort of 220 rapidly progressing patients treated with TV for 12 months. The tolerability of TV, the evolution of the estimated glomerular filtration rate (eGFR), analytical parameters, and blood pressure were analyzed.ResultsA total of 163 patients (78.2%) received TV for 1 year. The main causes of treatment withdrawal were the aquaretic effects (11%), eGFR deterioration (5%), and hepatic toxicity (2.3%). eGFR decreased significantly after 1 month of treatment without further changes. The decrease in eGFR in the first month was higher in patients with an initially higher eGFR. The eGFR drop during the first year of treatment with TV was lower than that reported by patients in the 2 years prior to TV treatment (–1.7 ± 7.6 vs. –4.4 ± 4.8 mL/min, p = 0.003). Serum sodium and uric acid concentrations increased, and morning urinary osmolality decreased in the first month, with no further changes. Blood pressure decreased significantly without changes in antihypertensive medication.ConclusionTV treatment is well tolerated by most patients. Liver toxicity is very rare and self-limited. TV reduces eGFR in the first month without showing further changes during the first year of treatment. Patients with a higher starting eGFR will suffer a greater initial drop, with a longer recovery. We suggest using the eGFR observed after a month of treatment as the reference for future comparisons and calculating the rate of eGFR decline in patients undergoing TV treatment.

Abstract
Introduction
Patients on hemodialysis are at high-risk for complications derived from coronavirus disease-19 (COVID-19). The present analysis evaluated the impact of a booster vaccine dose and breakthrough severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections on humoral immunity three months after the booster dose.
Methods
This is a multicentric and prospective study assessing IgG anti-Spike antibodies 6 and 9 months after initial SARS-CoV-2 vaccination in patients on hemodialysis that had also received a booster dose before the 6-month assessment (early booster) or between the 6- and 9-month assessments (late booster). The impact of breakthrough infections, type of vaccine, time from the booster and clinical variables were assessed.
Results
A total of 711 patients (67% male, 67 [20-89] years) were included. Of which, 545 (77%) received an early booster and the rest a late booster. At 6 months, 64 (9%) patients had negative anti-Spike antibody titers (3% of early booster and 29% of late booster patients, p = 0.001). At 9 months, 91% of patients with 6-month negative response had seroconverted and there were no differences in residual prevalence of negative humoral response between early and late booster patients (0.9% vs 0.6%, p = 0.693). During follow-up, 35 patients (5%) developed breakthrough SARS-CoV-2 infection. Antibody titers at 9 months were independently associated to mRNA-1273 booster (p = 0.001), lower time from booster (p = 0.043) and past breakthrough SARS-CoV-2 infection (p<0.001).
Conclusions
In hemodialysis patients, higher titers of anti-Spike antibodies at 9 months were associated to mRNA-1273 booster, lower time from booster and past breakthrough SARS-CoV-2 infection.

Abstract
BackgroundIrisin is a myokine synthesized mainly in skeletal muscle with exercise, although its secretion has also been observed in other tissues such as adipose and has been related to obesity and other metabolic alterations. Although obesity and other metabolic factors are risk factors for knee osteoarthritis and patients with this condition often do less exercise and have poor muscular state, irisin has been poorly studied.ObjectivesTo measure irisin levels in synovial fluid and plasma and evaluate their relationship with clinical severity and inflammation parameters in patients with knee osteoarthritis.MethodsPatients with symptomatic and radiographical osteoarthritis were studied. Demographic and anthropometric variables, Kellgren-Lawrence scale radiographic stage, the presence of synovial fluid and hypertrophy on ultrasound (at medial patellar line), clinical severity by Lequesne algofunctional index and physical exercise level were recorded. Levels of irisin, IL-6, TNF and hs-PCR were determined using ELISA.ResultsWe included 168 women (age 69 ±1.5 y, symptoms duration 48 ±3 m) and 31 men (age 66.5 ±4 y, symptoms duration 36 ±12 m). Significantly higher levels of irisin in synovial fluid were observed in women who did not perform any physical exercise compared to those who did exercise sporadically or regularly (p.0.05), while in plasma a non-significant trend was observed. A weakly positive correlation between intraarticular levels (r= 0.17, p .0.05) and plasma levels (r= 0.16, p. 0.05) of irisin and Lequesne index in women was also evidenced. Regarding inflammatory parameters, in female patients the synovial levels of irisin presented a weak positive correlation with the synovial levels of IL-6 (r= 0.18, p< 0.05) but not in plasma; an association was also found in women between synovial levels of irisin and synovial fluid >8 mm and severe synovial hypertrophy (p<0.05) in women, but not with plasma levels. All significant associations disappeared when adjusting by IMC except in the case of synovial hypertrophy. No statistically significant results were obtained in men.ConclusionLevels of irisin are related to gender and obesity in patients with knee osteoarthritis. However, the association with the intraarticular levels of IL-6 and the synovial hypertrophy could point to a possible local inflammatory effect at intraarticular level.Disclosure of InterestsNone declared

Abstract
Abstract
BACKGROUND AND AIMS
Diabetes mellitus (DM) is a complication in kidney transplant (KT). Therapies such as glucagon-like peptide-1 receptor agonist analogs (GLP-1RA) have been incorporated that could have benefits in KT, although experience is limited [1, 2]. The objective of our study is to describe the effectiveness and safety of GLP-1RA in KT patients.
METHOD
Retrospective cohort study of KT with DM who started GLP-1RA between February 2016 and December 2021. Clinical and demographic variables were analyzed. We collected GLP-1RA type and dose. Glomerular filtration rate (eGFR), proteinuria and weight were collected at the start of treatment and after 6 and 12 months. We analyze glycemic control, blood pressure and lipid profile. Acute rejections (AR), de novo donor-specific antibodies (DSA) and adverse effects were documented. A descriptive analysis was performed and the variables described before and after the start of treatment were compared. Parametric and non-parametric tests were performed according to the normality of the sample.
RESULTS
In this period, 50 KT with DM treated with GLP-1RA in our center from 1 March 2016 to 15 December 2021. Sixteen patients (32%) had developed post-transplant diabetes mellitus (PTDM). The mean age was 62.8 years and 52.5% were men. Mean baseline estimated glomerular filtration rate (eGFR) was 46.1 mL/min/1.73 m2 and the time post-KT was 38 months. The GLP-1RA mostly prescribed was semaglutide (47.5%), followed by liraglutide (32.5%) and dulaglutide (20%). Twenty-nine patients (58%) reached the maximum recommended dose of the drug. All patients received steroids, tacrolimus and mycophenolate. Forty KT recipients had a minimum follow-up of 6 months and 26 were followed for 12 months. Values of variables compared during the follow-up are shown in Table 1.
We observed an improvement in eGFR (+3.5 mL/min/1.73 m2 at 12 months, P = 0.030) and a reduction in proteinuria (−59.1 mg/g at 6 months, P = 0.009 and −48.5 mg/g at 12 months, P = 0.021) during all the follow-up. Additionally, we found a significant reduction in systolic blood pressure (−9.2 mmHg at 12 months, P = 0.022) despite the number of patients receiving angiotensin receptor blockers, angiotensin-converting enzyme and other antihypertensive therapies as well as their doses that did not change during the period of the study. In our cohort, body weight significantly reduced (−2.4 Kg at 6 months, P = 0.006 and −3 Kg at 12 months, P = 0.041). Furthermore, HbA1c decreased (−9 mmol/mol at 6 months, P <0.001 and −5 mmol/mol at 12 months, P = 0.018). Notably, insulin dose was also reduced (−4 UI/day at 6 months, P = 0.003 and −4 UI/day at 12 months, P = 0.036) and the rest of antidiabetic treatment did not significantly change. Finally, we observed a reduction in total cholesterol (−14 mg/dL at 6 months, P = 0.015 and −6.3 mg/dL at 12 months, P = 0.344) and LDL-c (−8.8 mg/dL at 6 months, P = 0.49 and −4.9 mg/dL at 12 months, P = 0.384) during the follow-up.
Twelve patients (24%) suffered from side effects, mainly nausea and vomiting, and only two patients (4%) discontinued the treatment. One patient discontinued the treatment due to the diagnosis of pancreatic cancer 8 months after starting the drug.
We did not find differences in the levels or in the dose of tacrolimus. Neither AR episodes nor de novo DSAs’ development was notified.
CONCLUSION
In conclusion, this is one of the largest series reporting the effectiveness and safety of GLP-1RA in a cohort of KT. Our results support that it can be an option for the management of DM in these patients. Its use is safe and it does not seem to alter tacrolimus trough levels, to induce AR episodes or de novo DSAs development.

Abstract
Abstract
BACKGROUND AND AIMS
BK virus infection (BKi) is an important cause of kidney transplant (KT) loss. Besides to reducing immunosuppression, the rest of the therapies have not shown a clear benefit. Our purpose is to analyze the risk factors for BKi and the influence of BK plasma viral load on KT outcomes.
METHOD
Prospective cohort study of KT with BKi, defined by the presence of BK viremia in ≥3 consecutive determinations, from 01 January 2010 to 31 December 2020. BK viremia was determined every 10 days during the first 3 months, at 6th month, 12th month and in case of impaired renal function. In patients with positive viremia, immunosuppressive therapy was changed (reduction/discontinuation of mycophenolate and/or switching to everolimus). Patients with high-level viremia (≥10 000 copies/mL) and low-level viremia (<10 000 copies/mL) were compared. To identify risk factors for BKi, for each KT with BKi, we selected two matched controls and performed a logistic regression analysis. Graft survival was analyzed according to BK viremia (high-level, low-level and negative) using Kaplan–Meier and Cox regression analysis was performed to determine risk factors for graft survival.
RESULTS
849 KT were performed, of which 67 (7.9%) presented BKi. Six KT were excluded due to incomplete data. Finally, 61 KT BKi (n = 27, high-level viremia; n = 34 low-level viremia) and 122 controls were analyzed. The median post-KT time to BKi was 2 months. In the multivariable analysis, male recipient, older age and re-KT were risk factors for BKi.
Proven BK-associated nephropathy was diagnosed in five KT recipients and nine patients had persistent BK viremia, all of them from the high plasma viral loads group. Only one patient lost the graft due to BK-associated nephropathy.
Patients with low-level viremia had worse renal function one month after KT than controls but without differences at the first year. Patients with high-level viremia had worse renal function one year after KT and worse graft survival than recipients with low-level viremia and controls (P = 0.037). In the multivariable analysis, when we analyzed exclusively patients with BKi, high-level viremia was a risk factor for kidney graft survival (HR: 16.31; P = 0.034).
CONCLUSION
BKi is not an uncommon complication after KT. Only high BK viral load was associated with BK-associated nephropathy, persistent viremia, and poorer graft survival. BK viremia <10 000 copies/mL did not affect KT outcomes. Therefore, monitoring BK plasma viral loads and changes in immunosuppression to reduce viremia are effective strategies to minimize the impact of BK virus on graft survival.

Abstract
BACKGROUND AND OBJECTIVE To describe the clinical characteristics, the reasons for initiating therapy and the effects of treatment in the initial phase of evolocumab availability in the Nephrology Units of Spain. MATERIAL AND METHODS Retrospective, observational and multicentric study that included patients initiating treatment with evolocumab (from February 2016 to August 2018), in 15 Nephrology Units in Spain. The demographic and clinical characteristics of the patients, the lipid lowering treatment and the evolution of the lipid profiles between 24 weeks pre-initiation and 12±4 weeks post-initiation of evolocumab were reviewed. RESULTS 60 patients were enrolled: 53.3% women; mean (SD) age, 56.9 (12.8) years, 45.0% with familial hypercholesterolemia (FH) (5.0% homozygous and 40.0% heterozygous) and 65.0% with atherosclerotic cardiovascular disease. The mean (SD) eGFR was 62.6 (30.0) ml/min/1.73m2 (51.7% of patients had eGFR <60ml/min/1.73m2 [CKD stage>2]), 50.0% had proteinuria (>300mg/g) and 10.0% had nephrotic syndrome. Other CV risk factors were hypertension (75.0%), diabetes (25.0%), and smoking (21.7%). A 40.0% of patients were statin intolerant. At evolocumab initiation, 41.7% of patients were on a high intensity statin, 18.3% on moderate intensity statin and 50.0% were receiving ezetimibe. Mean (SD) LDL-c at evolocumab initiation was 179.7 (62.9) mg/dL (53.4% of patients with LDL-c ≥160mg/dL and 29.3% ≥190mg/dL). After 12 weeks, evolocumab resulted in LDL-c reductions of 60.1%. At week 12, 90.0% of patients reached LDL-c levels <100mg/dL, 70.0% <70mg/dL, and 55.0% <55mg/dL, while mean eGFR levels and statin use remained stable. CONCLUSION In Nephrology Units of Spain, evolocumab was predominantly prescribed in patients with FH, chronic renal disease (CRD>2) and secondary prevention, with LDL-c levels above those recommended by the guidelines. Evolocumab used in clinical practice significantly reduced the LDL-c levels in all patients included in the study.

Abstract
BACKGROUND AND OBJECTIVE To describe the clinical characteristics, the reasons for initiating therapy and the effects of treatment in the initial phase of evolocumab availability in the Nephrology Units of Spain. MATERIAL AND METHODS Retrospective, observational and multicentric study that included patients initiating treatment with evolocumab (from February 2016 to August 2018), in 15 Nephrology Units in Spain. The demographic and clinical characteristics of the patients, the lipid lowering treatment and the evolution of the lipid profiles between 24 weeks pre-initiation and 12±4 weeks post-initiation of evolocumab were reviewed. RESULTS Sixty patients were enrolled: 53.3% women; mean (SD) age, 56.9 (12.8) years, 45.0% with familial hypercholesterolemia (FH) (5.0% homozygous and 40.0% heterozygous) and 65.0% with atherosclerotic cardiovascular (CV) disease. The mean (SD) eGFR was 62.6 (30.0)ml/min/1.73m2 (51.7% of patients had eGFR<60ml/min/1.73m2 [CKD stage>2]), 50.0% had proteinuria (>300mg/g) and 10.0% had nephrotic syndrome. Other CV risk factors were hypertension (75.0%), diabetes (25.0%), and smoking (21.7%). A 40.0% of patients were statin intolerant. At evolocumab initiation, 41.7% of patients were on a high-intensity statin, 18.3% on moderate intensity statin and 50.0% were receiving ezetimibe. Mean (SD) LDL-c at evolocumab initiation was 179.7 (62.9)mg/dL (53.4% of patients with LDL-c≥160mg/dL and 29.3%≥190mg/dL). After 12 weeks, evolocumab resulted in LDL-c reductions of 60.1%. At week 12, 90.0% of patients reached LDL-c levels <100mg/dL, 70.0% <70mg/dL, and 55.0% <55mg/dL, while mean eGFR levels and statin use were remained stable. CONCLUSION In Nephrology Units of Spain, evolocumab was predominantly prescribed in patients with FH, chronic renal disease (CRD>2) and secondary prevention, with LDL-c levels above those recommended by the guidelines. Evolocumab used in clinical practice significantly reduced the LDL-c levels in all patients included in the study.

Abstract
Background:Rheumatoid Arthritis (RA) is a systemic autoimmune disease, associated with hiperproduction of autoantibodies (AAb), in which the most specific are the AAb against citrullinated peptides (ACPA). RA is influenced by genetic factors, specifically, there is a strong genetic association with the shared epitope (SE), a five amino acid sequence motif in positions 70–74 of HLA-DRβ1 chains encoded by HLA-DRB1 alleles: QKRAA, QRRAA and RRRAA.The present study aims to analyze whether SE-peptides (SE-p) can be a target of the autoimmune response in RA.Objectives:To analyze the presence of AAb against the unmodified (Un) SE-p, citrullinated (Cit) SE-p and carbamylated (Car) SE-p.Methods:Sera from consecutive 117 RA patients and 21 psoriasic arthritis (PsA) from our outpatient clinic were collected by venopunture. Also 138 sera from blood donors were obtained as healthy controls (HC). All participants signed the informed consent.We perfomed a homemade ELISA test using a sequence of 15 aminoacid peptides from positions 65-79 of HLA-DRB1 containing the 3 different SE sequences, in the Un, Cit and Car SE-p, synthesized in a linear and cycled form. We established a 90% of specificity using a ROC curve obtained from HC and PsA for each ELISA test.HLA-DRB1 polymorphism was performed using a HLA-DRB1 sequence specific oligonucleotide typing kit (Lifecodes) in 95 RA and in 15 PsA.ACPA and RF were determined with commercial assays (Inova Diagnostics and Binding Site, respectively).Results:The overall sensitivity of the different SE-p AAb tests ranged from 5.1-21.4%.RRRAA SE polymorphism was associated with AAb against cycled CitCitCitAA SE-p (p=0.025), QKRAA polymorphism was almost significantly associated with AAb against cycled QKCitAA SE-p (p=0.067), whereas there was no association between QRRAA polymorphism and AAb against cycled QCitCitAA SE-p (p=0.690). On the other hand, there was no association between SE polymorphisms and AAb to any other peptide used in the ELISA test.Significant differences were observed in the presence of AAb against lineal RRRAA, lineal CitCitCitAA and cycled CitCitCitAA SE-p when comparing RA vs. HC patients (p=0.022, 0.044, 0.022, respectively). Moreover, there also were significant differences in the presence of AAb against cycled CitCitCitAA SE-p between RA and PsA patients (sensitivity 21.4%, specificity 100%; p=0.014).It must be highlighted that cycled CitCitCitAA SE-p AAb were detected in 20.0% of RA patient sera that were negative for RF and ACPA.There was no association between RF or ACPA with the presence of any SE-p AAb.Conclusion:RA patients have autoantibodies against the Shared Epitope (SE). The cycled CitCitCitAA SE peptide (SE-p) shows the best performance among all the peptides tested and could identify patients seronegative for ACPA and RF, both analyzed by commercial assays.Additional studies must be performed to verify the diagnostic and utility of these new autoantibodies against SE-p in RA.Acknowledgements:This work was granted by the 2018 call of the “Fundación Española de Reumatologia” and the 2017 call grant “Fundació Parc Taulí”.Disclosure of Interests:None declared

Abstract
Abstract
Background
Childbirth has been suggested to increase sickness absence (SA) and disability pension (DP). This may vary by occupation; however, knowledge in this field remains limited. We explored SA and DP in the years before and after childbirth among women in four occupational groups and among those without any occupation.
Methods
We conducted a register-based study of nulliparous women aged 18-39 years, living in Sweden on December 31, 2004 (n = 492,504). Women were categorized into five skill-level based occupational groups and three childbirth groups; no childbirths within three years (B0), first childbirth in 2005 with no childbirth within three years (B1), and first childbirth in 2005 with at least one more birth within three years (B1+). We compared crude and standardized annual mean SA (in spells>14 days) and DP net days in the three years before and three years after first childbirth date.
Results
Women in the highest skill level occupations and managers had generally lower mean SA/DP days e.g., B0: 11.3, B1: 11.6, B1+: 6.8 during the third year after first childbirth than the lowest skill level occupations group; B0: 28.1, B1: 22.8, B1+: 15.2 days. In B1 and B1+, absolute differences in mean SA/DP, particularly in SA, among occupational groups were highest during the year before childbirth. DP was most common in B0, regardless of group and year.
Conclusions
We found that women's mean SA/DP days before and after first childbirth were higher with decreasing skill-level of the occupational group, with these differences being most pronounced in the year before childbirth. DP was most common among women not giving birth, regardless of occupational group.
Key messages
Women’s mean SA/DP days before and after first childbirth increased with decreasing skill-level of the occupational group and these differences were most pronounced in the year before childbirth.

Abstract
Abstract
Background and Aims
Cardiovascular disease is the primary cause of morbidity and mortality in patients with chronic kidney disease (CKD). Evolocumab is a monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and lowers serum low density lipoprotein cholesterol (LDL-C) levels. Evolocumab is indicated for adult patients with hypercholesterolaemia or mixed dyslipidaemia who are unable to reach LDL-C goals with the maximum tolerated dose of statin or are statin intolerant. This study was conducted to describe clinical characteristics, reasons for therapy initiation and treatment effects in patients treated with evolocumab in Spanish Nephrology units.
Method
Retrospective, observational, chart review of consecutive patients initiating evolocumab (Feb-2016 to Aug-2018) in 15 Spanish Nephrology Units. Patient characteristics, lipid modifying therapies and lipid profiles over time were retrospectively collected at 24 weeks pre- and 12±4 weeks post-evolocumab initiation.
Results
60 patients were enrolled: 53.3% women; mean (SD) age, 56.9 (12.8) years; mean (SD) body mass index, 28.0 (4.7) kg/m2; 45.0% had familial hypercholesterolemia (FH) (5.0% homozygous, 23.3% heterozygous, 16.7% undetermined FH); from the total population, 35% were in primary prevention and 65.0% started evolocumab after previous Atherosclerotic Cardiovascular Disease [ASCVD]. Regarding renal function, mean (SD) eGFR was 62.6 (30.0) ml/min/1.73m2; 51.7% of patients had eGFR <60 ml/min/1.73m2 (CKD stage>2), 50.0% had proteinuria (>300 mg/g) and 10.0% had nephrotic syndrome. Other CV risk factors were hypertension (75.0%), diabetes (25.0%), and smoking (21.7%); 40.0% of patients were statin intolerant. At evolocumab initiation, 41.7% of patients were on a high intensity statin, 18.3% on moderate intensity statin and 50.0% were receiving ezetimibe. Mean (SD) LDL-C at evolocumab initiation was 179.7 (62.9) mg/dL (53.4% of patients with LDL-C≥160; 29.3% ≥190). Mean (SD) baseline HDL-C and total cholesterol were 48.5 (15.0) mg/dL and 273.1 (82.7) mg/dL, respectively. After 12 weeks, evolocumab resulted in LDL-C reductions of 60.1%, to a mean (SD) of 72.7 (80.3) mg/dL, with similar results observed in patients in primary/secondary prevention, with CKD stage >2/≤2 or with/without proteinuria. Conversely, patients with/without FH showed significant differences between their reductions (46.6% vs 76.6%, respectively, p=0.0276). At week 12, 90.0% of patients reached LDL-C levels <100 mg/dL, 70.0% <70 mg/dL, and 55.0% <55mg/dL, while eGFR levels and statin use remained stable.
Conclusion
In Spanish Nephrology Units, evolocumab was predominantly prescribed in patients with FH, ASCVD and/or CKD stage >2. Initial evolocumab use was aligned with ESC/EAS dyslipidaemia guidelines, but with higher baseline LDL-C levels than the recommended thresholds. After 12 weeks of evolocumab treatment, LDL–C levels were more than halved and the majority of patients achieved both the 2016 and 2019 EAS/ESC targets of LDL-C control.

Abstract
Abstract
Background
Childbirth is suggested to be associated with elevated levels of sickness absence (SA) and disability pension (DP). However, knowledge about patterns of SA/DP before and after childbirth as compared to patterns among women who remain nulliparous is limited. We aimed to compare SA/DP across several periods among women with different childbirth status.
Methods
We analysed three population-based cohorts of all women aged 18-39 years who had not previously given birth and who lived in Sweden on 31 December 1994, 1999, or 2004, respectively. We compared crude and standardized annual mean SA and DP net days during three years preceding to three years after the date of first childbirth, among women having (1) their first and only birth during the subsequent three years, (2) their first birth and at least another delivery, and (3) no childbirths before, nor during the study period.
Results
Despite an increase in SA in the year preceding the first childbirth, women who gave birth, and especially women with multiple births, tended to have lower levels of SA/DP days throughout the years than women without childbirths. SA/DP days varied across age groups; young women (aged 18-24 years) without childbirths had fewer SA days, but more DP days than their same-aged counterparts who gave birth, regardless of year. These results did not differ across the three cohorts, suggesting that the results were not affected by period effects.
Conclusions
Women with more than one childbirth had fewer days of SA and DP, as compared to women with one childbirth and to women having no births. Thus, childbirth does not seem to be associated with higher levels of SA and DP. Some of these results can be due to a health selection into giving birth, especially having more births.
Key messages
Except for the year before delivery, i.e., when pregnant, women giving birth had fewer SA and DP days than women with no births. Thus, childbirth does not seem to be associated with higher SA and DP. Women who had more than one childbirth had less SA/DP days than those with one childbirth.

Abstract
OBJECTIVES HistoScanning™ (HS) is a method of ecographic diagnosis of prostate cancer. We analyze the effectiveness of the HS realization prior to the biopsies for the prostate adenocarcinoma diagnosis. MATERIAL AND METHODS From August to October 2012 we have carried out a study with HS prior to the biopsies in 32 patients. In all cases sextants transrectal biopsies have been realized (two cores in each sextant) in the periphery zone. In those sextants in which there were suspicious areas with HS, the biopsies were addressed to those areas. Transperineal biopsies were added to those zones placed in the half-front or apical prostatic zone. The medium age was 63.7 years (range 40-82) with a medium PSA of 8.0 ng/ml (range 3.5-36.2) and a medium prostatic volume of 46.6cc (range 18.2-103.2). In eight cases it was the first biopsy, in 14 cases they were repetition biopsies and 10 patients had a previous diagnosis of prostate adenocarcinoma (8 in a program of active surveillance and 2 T1a in RTU of previous prostate). RESULTS In the 32 patients a medium of 7,5 zones were biopsied (range 6-9) with a total of 239 zones studied. There were identified a medium of 3.2 zones with suspicious areas (ZS) with HS (range 2-5) with a total of 103 ZS. In 72 zones of 25 patients it was found adenocarcinoma or PIN (2 PIN, 11 score Gleason 6, 7 score Gleason 7, 3 score Gleason 8 and 2 score Gleason 9). There were 35 positive false zones in 20 patients (11 normal parenquima and 9 chronic inflammation). Negative falses were produced in 5 zones in 5 patients (2PIN, 2 score Gleason 6 and 1 score Gleason 7) although in all 5 cases adenocarcinoma was encountered (o discovered) in other zones. The HS presented a sensibility of a 93.5% with a specificity of 79.5%. The positive predictive value was of the 67.35% with a negative predictive value of 96.5%. CONCLUSIONS In spite of being a selected serie, with a high rate of patients with adenocarcinoma, the exploration with HS has presented a great sensibility and a high negative predictive value. These data, although they must be confirmed in less selected series, state that the prior exploration with HS can help as in the diagnostic in the biopsies as in the follow-up of programs of active surveillance.

Abstract
The structural elucidation of 2α-cyclodextrin/1-octanethiol, 2α-cyclodextrin/1-octylamine and 2α-cyclodextrin/1-nonanoic acid inclusion complexes by nuclear magnetic resonance (NMR) spectroscopy and molecular modeling has been achieved. The detailed spatial configurations are proposed for the three inclusion complexes based on 2D NMR method. ROESY experiments confirm the inclusion of guest molecules inside the α-cyclodextrin (α-CD) cavity. On the other hand, the host-guest ratio observed was 2:1 for three complexes. The detailed spatial configuration proposed based on 2D NMR methods were further interpreted using molecular modeling studies. The theoretical calculations are in good agreement with the experimental data.

Abstract
Mutations in the spindle checkpoint genes can cause improper chromosome segregations and aneuploidies, which in turn may lead to reproductive problems. Two of the proteins involved in this checkpoint are Aurora kinase B (AURKB), preventing the anaphase whenever microtubule-kinetochore attachments are not the proper ones during metaphase; and synaptonemal complex protein 3 (SYCP3), which is essential for the formation of the complex and for the recombination of the homologous chromosomes. This study has attempted to clarify the possible involvement of both proteins in the reproductive problems of patients with chromosomal instability. In order to do this, we have performed a screening for genetic variants in AURKB and SYCP3 among these patients using Sanger sequencing. Only one apparently non-pathogenic deletion was found in SYCP3. On the other hand, we found six sequence variations in AURKB. The consequences of these changes on the protein were studied in silico using different bioinformatic tools. In addition, the frequency of three of the variations was studied using a high-resolution melting approach. The absence of these three variants in control samples and their position in the AURKB gene suggests their possible involvement in the patients' chromosomal instability. Interestingly, two of the identified changes in AURKB were found in each member of a couple with antecedents of spontaneous pregnancy loss, a fetal anencephaly and a deaf daughter. One of these changes is described here for the first time. Although further studies are necessary, our results are encouraging enough to propose the analysis of AURKB in couples with reproductive problems.

Abstract
SUMMARY In a cross-sectional study including 324 patients older than 65 years admitted to our hospital for osteoporotic hip fracture, we found that those patients with a more severe vitamin D deficiency had more severe osteoporotic hip fractures (Garden grades III-IV and Kyle III-IV). INTRODUCTION To identify possible differences in baseline characteristics of patients with different types of osteoporotic hip fracture. METHODS Cross-sectional study including consecutive individuals over 65 admitted to our hospital for osteoporotic hip fracture over a year. Demographic data, fracture type, comorbidities, history of osteoporosis, functional capacity, nutritional status and vitamin D storage were evaluated. RESULTS We included 324 patients (83 ± 7 years, 80% women). Two hundred sixteen patients (67%) had vitamin D deficiency (25OHD3 <25 ng/ml). In patients with severe femoral neck or intertrochanteric fractures (Garden III-IV and Kyle III-IV), vitamin D deficiency was more frequent (74%) and severe (25OHD3 20 ± 15 ng/ml) than in patients with less severe fractures (57%, 25OHD3 26 ± 21 ng/ml). Forty-three percent of patients had previous fractures. Only 15% of patients had been previously diagnosed with osteoporosis and 10% were receiving treatment. Patients receiving vitamin D supplements have higher 20OHD3 levels and less severe fractures. CONCLUSIONS Although vitamin D levels are not different between patients with intracapsular or extracapsular hip fractures, a more severe vitamin D deficiency seems to be associated to more severe osteoporotic hip fractures. A prior vitamin D supplementation could avoid a higher severity of these fractures.

Abstract
PURPOSE Most neuroblastoma patients over 18 months of age at diagnosis present disseminated disease. The presence of neuroblastoma cells in bone marrow can be used to evaluate the response to treatment. It is possible that alterations in certain tumour cells might confer a selective advantage over tumour dissemination process, and probably be helpful in the clonal selection of tumour-specific cells that could originate metastasis. METHODS We performed real-time quantitative PCR to identify the presence of disseminated tumour cells in bone marrow samples, and we used MSP to analyse the methylation profile of 20 genes putatively implied in dissemination. RESULTS We described epigenetic alterations in the methylated status of certain genes in disseminated tumour cells from bone marrow. Those cases with high rate of hypermethylation showed an increased probability of relapse during or after treatment. We found significantly poor prognosis in event-free survival in cases with hypermethylation of TMS1, MGMT and RARbeta2 genes. CONCLUSION We could not confirm the presence of a specific methylation profile in disseminated neuroblastoma tumour cells, but a high accumulation of epigenetic events in those cells is associated with a high risk of relapse, independently of MYCN amplification.

Abstract
Submicroscopic deletions of 1q44-qter cause severe mental retardation, profound growth retardation, microcephaly and corpus callosum hypo/agenesis in most patients. At least 3 intervals in 1q44 have been described as critical regions containing genes leading to corpus callosum abnormalities. In this report we describe a patient with a de novo small interstitial 1q44 deletion of 1,152 kb detected with 44K oligonucleotide array-CGH (44K Agilent Technologies) and a mild phenotype lacking corpus callosum abnormalities. The first deleted oligonucleotide was located at 242.638 Mb (within the ADSS gene), and the last deleted oligonucleotide at 243.791 Mb (within the KIF26B gene). The clinical and molecular findings of the patient here reported remain consistent with a role for the AKT3 or ZNF238 genes in corpus callosum development.

Abstract
This report describes a case of mosaic Down syndrome due to an unusual karyotype in a patient conceived by assisted reproductive techniques and cryopreservation. The chromosomal complement consists of two different cell lines, one predominantly trisomic with a derivative chromosome due to a Robertsonian translocation (21;21) and another carrying a ring chromosome 21. The present work analyses the different mechanisms that could have led to mosaicism.
