Abstract
In this paper, we investigate the common narrative in literary history that the inner lives of characters became a central preoccupation of literary modernism - a phenomenon commonly referenced as the "inward turn". We operationalize this notion via a proxy, tracing the use of verbs relating to inner life across 10 language corpora from the ELTeC collection, which comprises novels from the period between 1840-1920. We expected to find an increase in the use of inner-life verbs corresponding to the traditional periodisation of modernism in each of the languages. However, different experiments conducted with the data do not confirm this hypothesis. We therefore look at the results in a number of more granular ways, but we cannot identify any common trends even when we split the verbs into individual categories, or take canonicity or gender into account. We discuss the obtained results in detail, proposing potential reasons for them and including potential avenues of further research as well as lessons learned.

Abstract
INTRODUCTION Diabetes mellitus (DM) impairs wound healing. The aim was to determine whether DM influences mitochondrial respiration in wounded skin (WS) and non-wounded skin (NWS), in a pre-clinical wound healing model of streptozotocin (STZ)-induced diabetes. METHODS Six weeks after diabetes induction, two wounds were created in the back of C57BL/J6 mice. Using high-resolution respirometry (HRR), oxygen flux was measured, in WS and NWS, using two substrate-uncoupler-inhibitor titration protocols, at baseline (day 0), day 3 and 10 post-wounding, in STZ-DM and non-diabetic (NDM) mice. Flux control ratios for the oxidative phosphorylation (OXPHOS) capacity were calculated. RESULTS A significant increase in mitochondrial respiration was observed in STZ-DM skin compared to control skin at baseline. The OXPHOS capacity was decreased in WS under diabetes at day 3 post-wounding (inflammation phase). However, at day 10 post-wounding (remodeling phase), the OXPHOS capacity was higher in WS from STZ-DM compared to NDM mice, and compared to NWS from STZ-DM mice. A significant relative contribution of pyruvate, malate and glutamate (PMG) oxidation to the OXPHOS capacity was observed in WS compared to NWS from STZ-DM mice, at day 10, while the relative contribution of fatty acid oxidation to the OXPHOS capacity was higher in NWS. The OXPHOS capacity is altered in WS from STZ-DM compared to NDM mice across the healing process, and so is the substrate contribution in WS and NWS from STZ-DM mice, at each time point. CONCLUSION HRR may be a sensitive tool to evaluate the underlying mechanisms of tissue repair during wound healing.

Abstract
INTRODUCTION Neurocysticercosis (NCC), a possible cause of epilepsy with limited epidemiological data in the Dominican Republic, is endemic in four provinces in the country's south-western region. This study aimed to determine the association between NCC and epilepsy among people living in these endemic regions, and to obtain preliminary data on the prevalence of NCC in these provinces. PATIENTS AND METHODS A case-control design was used, consisting of 111 patients with epilepsy with unknown causes, and 60 controls without epilepsy or NCC. The diagnosis of NCC was based on computed tomography and magnetic resonance imaging of the skull, as well as Western immunoblotting for serum antibodies using Taenia solium, following the criteria of Del Brutto et al. RESULTS. NCC was found in 27% of the epileptic patients (n = 30/111) and in 5% of the controls (n = 3/60); the probability of the epileptic patients having NCC was seven times higher than the controls (odds ratio = 7.04, 95% confidence interval: 2.04-24.18; p < 0.001). The participants' sociodemographic characteristics, including their age, sex, level of education, occupation, and province of residence presented no statistical significance in terms of their association with NCC. CONCLUSIONS This study suggests that NCC is strongly associated with epilepsy in the south-western region of the Dominican Republic, and highlights the need for public health measures to improve the prevention, diagnosis and treatment of both diseases.

Abstract
FANCJ, a DNA helicase linked to Fanconi anemia and frequently mutated in cancers, counteracts replication stress by dismantling unconventional DNA secondary structures (such as G-quadruplexes) that occur at the DNA replication fork in certain sequence contexts. However, how FANCJ is recruited to the replisome is unknown. Here, we report that FANCJ directly binds to AND-1 (the vertebrate ortholog of budding yeast Ctf4), a homo-trimeric protein adaptor that connects the CDC45/MCM2-7/GINS replicative DNA helicase with DNA polymerase α and several other factors at DNA replication forks. The interaction between FANCJ and AND-1 requires the integrity of an evolutionarily conserved Ctf4-interacting protein (CIP) box located between the FANCJ helicase motifs IV and V. Disruption of the CIP box significantly reduces FANCJ association with the replisome, causing enhanced DNA damage, decreased replication fork recovery and fork asymmetry in cells unchallenged or treated with Pyridostatin, a G-quadruplex-binder, or Mitomycin C, a DNA inter-strand cross-linking agent. Cancer-relevant FANCJ CIP box variants display reduced AND-1-binding and enhanced DNA damage, a finding that suggests their potential role in cancer predisposition.

Abstract
BACKGROUND The Distress Tolerance Scale (DTS) was adapted for American and Chinese youth, but never for European youth. Moreover, the factor structures found in these previous studies were not consistent. METHODS The DTS was adapted for Portuguese children and then validated among 153 children aged 6-13 years with emotional disorders. A confirmatory factor analysis (CFA) was conducted; the DTS reliability and validity were analyzed, and sex and age differences were explored. A sub-sample of children who received a transdiagnostic CBT (Unified Protocol for Children) was used to analyze the DTS's sensitivity to therapeutic change. RESULTS The five tested models (based on previous studies) exhibited adequate fit in the CFA. However, the model previously reported for use in American children with emotional disorders was selected as the most appropriate. The DTS demonstrated adequate psychometric properties, and its validity was established through significant negative associations with measures of anxiety, depression and negative affect, as well as positive associations with positive affect. Age and sex differences were discussed. The DTS scores significantly increased from pre- to post-treatment, demonstrating sensitivity to therapeutic change. CONCLUSIONS The DTS is a suitable and useful measure for assessing children's distress tolerance and to assess the efficacy of CBT.

Abstract
The Brazilian Midwest is responsible for 54.3% of the country's soybean production. Adequate storage technologies are essential to maintain physical, physiological, and sanitary seed qualities while also minimizing deterioration processes and consequent germination and vigor declines. In this context, the aim of the present study was to evaluate the physiological potential and physical qualities of soybean seeds stored under different environmental conditions and storage bag depths. Assays were carried out in September 2021 employing Foco 74i77 RSF IPRO cultivar seeds stored from April to August 2021 under three conditions, as follows: chilled at an average temperature of ≤20 °C, at an average temperature of ≤25 °C using a with blanket, and in without blanket warehouse structure at an average temperature of ≥25 °C with no with blanket. A completely randomized 3x3 factorial experimental design was applied, comprising three storage environments and three bag positions (top, middle, and bottom), with three replication each. Physical, physiological, and biochemical tests were performed on the stored seeds. The findings indicate better seed preservation in the chilled environment or when using a with blanket, with significant differences noted for seeds stored the middle of the storage bag. Therefore, soybean seed storage in a chilled environment or using a with blanket aids in slowing down the seed deterioration processes, preserving physiological quality and vigor compared to a conventional storage environment. Additionally, the quality of soybean seeds stored under these conditions in the middle of storage bags is maintained.

Abstract
OBJECTIVE The objective of this review is to explore the lived experiences of critically ill adults, their families, or health care professionals with remote communication in intensive care units (ICUs) during the COVID-19 pandemic. INTRODUCTION Family visiting restrictions in ICUs during the COVID-19 pandemic imposed significant challenges to communication between critically ill adults, their families, and the health care team. Evidence shows that several communication strategies were developed and implemented in ICUs during the COVID-19 pandemic to promote family engagement; however, the experiences of critically ill adults, their families, and health care professionals with these strategies are scattered across primary qualitative studies. INCLUSION CRITERIA This review will consider qualitative studies that include critically ill adults, their families, or health care professionals, focusing on their experiences with remote communication strategies in ICUs during the COVID-19 pandemic. METHODS This review will be conducted in accordance with JBI methodology. The search strategy will aim to locate both published and unpublished qualitative studies in English, Spanish, and Portuguese. Studies published after January 2020 will be included. Study selection, critical appraisal, and data extraction will be performed independently by 2 reviewers. Data will be presented in narrative format and synthesized using the JBI meta-aggregation process. A ConQual Summary of Findings will be presented. REVIEW REGISTRATION PROSPERO CRD42022383603.

Abstract
OBJECTIVE This systematic review will assess the effectiveness of school-based sleep promotion programs on sleep knowledge, hygiene, quality, behavior, and efficiency in adolescents. INTRODUCTION Adolescents need to sleep between 8 and 10 hours per night; however, most sleep fewer hours due to peer and school pressure, stress, and excessive use of electronic devices at night. Sleep deprivation can lead to cardiovascular problems, issues with stress management, and suicidal ideation. Schools are an ideal space to implement intervention programs, providing the opportunity to reach a large number of adolescents. Considering the negative impacts of poor sleep, it is essential to assess the effectiveness of school-based sleep promotion programs on sleep knowledge, hygiene, quality, behavior, and efficiency. INCLUSION CRITERIA Studies with adolescents (10-19 years old) exposed to school-based sleep promotion programs will be included. Studies in English, Spanish, and Portuguese will be considered, with no time limits. METHODS Nine databases, CINAHL, Cochrane Central Register of Controlled Trials, ERIC (all via EBSCOhost), MEDLINE (PubMed), LILACS, SciELO, Psychology and Behavioral Sciences Collection, Web of Science Core Collection, and Scopus, will be searched from inception to identify relevant studies. Two independent reviewers will perform the study selection, critical appraisal using JBI tools, and data extraction. Studies will, where possible, be pooled in meta-analysis. Heterogeneity will be assessed using the standard χ 2 and I2 tests. Statistical analyses will be performed using the random effects model. If fewer than 5 studies are included, the fixed effects model will be used. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach will be used to grade the certainty of evidence and a Summary of Findings will be created.

Abstract
Fatty acids are energy sources, and their profiles are used as biomarkers of metabolic status and physiological changes in fish. Within this context, the main aim of this study was to identify the fatty acids that best discriminate the reproductive status of male and female farmed brown trout. The fatty acid composition in liver and plasma samples from the adults of both sexes was monitored along four distinct reproductive stages, namely the spawning capable (December), regressing (March), regenerating (July), and developing (November) stages. Irrespective of the sex and stage, the most representative fatty acids were palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1 n-9), arachidonic acid (20:4 n-6), eicosapentaenoic acid (EPA, 20:5 n-3), and docosahexaenoic acid (DHA, 22:6 n-3). There were no significant sex differences in fatty acid classes in the liver and plasma. Despite this, there were several changes in individual fatty acid levels between the sexes. In the liver, both males and females showed high monounsaturated fatty acid and low polyunsaturated fatty acid (PUFA) levels during the regressing and regenerating stages. At spawning capable and developing stages, a reverse profile was noted. The plasma profiles were mainly influenced by changes in saturated fatty acids and PUFAs in males and by PUFA in females. Based on the most representative fatty acids, four patterns were established for female plasma samples, one for each reproductive stage. This scenario suggests that female plasma samples are promising for the discrimination of gonadal reproductive status, and this potential can be further explored in aquaculture and environmental monitoring studies.

Abstract
Objective: Diabetic foot ulcers (DFUs) are devastating complications of diabetes, responsible for a high number of amputations worldwide. Due to its impact on chronic inflammation, psychological distress may negatively impact the healing process. Thus, this study evaluated the influence of psychological distress on physiological indicators of healing prognosis and the potential of stress-reducing therapies for DFU healing. Approach: Patients with chronic DFU were recruited and assessed at enrollment and 2 months later. According to psychological scores at enrollment, participants were allocated into groups without (group 1) or with (group 3) psychological distress. Participants who reported clinical distress were then randomly allocated into a control (no stress-reducing intervention-group 4) or experimental (with stress-reducing interventions-group 5) group. Subsequently, indicators of healing prognosis were measured. Results: Groups 1 and 3 presented no differences in the Perfusion, Extent, Depth, Infection and Sensation score, glycated hemoglobin, or inflammatory and angiogenic markers. However, the immune cell ratio was increased by more than twofold in group 3, compared with group 1. Importantly, the expression of circulating microRNAs was significantly increased in group 3 (miR-21-5p, miR-155-5p, miR-146a-5p, and miR-221-3p [p < 0.05]), compared with group 1. Two months later, group 5 displayed a significant improvement in the Perceived Stress Scale and Hospital Anxiety and Depression Scale scores (p < 0.01), and the immune cell ratio was decreased by more than 2.5-fold. Innovation: This study helped to identify which variables and psychological interventions are more successful in promoting DFU healing. Conclusion: Psychological distress influenced clinical and physiological parameters, leading to compromised DFU healing and consequently underlining the potential of adjuvant stress-reducing approaches.

Abstract
Diabetic foot ulcers (DFU) are one of the most frequent and debilitating complications of diabetes. DFU wound healing is a highly complex process, resulting in significant medical, economic and social challenges. Therefore, early identification of patients with a high-risk profile would be important to adequate treatment and more successful health outcomes. This study explores risk assessment profiles for DFU healing and healing prognosis, using machine learning predictive approaches and decision tree algorithms. Patients were evaluated at baseline (T0; N = 158) and 2 months later (T1; N = 108) on sociodemographic, clinical, biochemical and psychological variables. The performance evaluation of the models comprised F1-score, accuracy, precision and recall. Only profiles with F1-score >0.7 were selected for analysis. According to the two profiles generated for DFU healing, the most important predictive factors were illness representations on T1 IPQ-B (IPQ-B ≤ 9.5 and < 10.5) and the DFU duration (≤ 13 weeks). The two predictive models for DFU healing prognosis suggest that biochemical factors are the best predictors of a favorable healing prognosis, namely IL-6, microRNA-146a-5p and PECAM-1 at T0 and angiopoietin-2 at T1. Illness perception at T0 (IPQ-B ≤ 39.5) also emerged as a relevant predictor for healing prognosis. The results emphasize the importance of DFU duration, illness perception and biochemical markers as predictors of healing in chronic DFUs. Future research is needed to confirm and test the obtained predictive models.

Abstract
PURPOSE To assess reading performance and report normative values for normal sighted Portuguese schoolchildren using the Portuguese version of the MNREAD reading acuity chart. METHODS Children in the 2nd, 4th, 6th, 8th, and 10th grade in Portugal were recruited for this study. One hundred and sixty-seven children from 7 to 16 years of age participated. The Portuguese version of the printed MNREAD reading acuity chart was used to measure reading performance in these children. The non-linear mixed effects model with negative exponential decay function was used to compute maximum reading speed (MRS) and critical print size (CPS) automatically. Reading acuity (RA) and reading accessibility index (ACC) were computed manually. RESULTS The mean MRS in words-per-minute (wpm) for the 2nd grade was 55 wpm (SD = 11.2 wpm), 104 wpm (SD = 27.9) for the 4th grade, 149 wpm (SD = 22.5) for 6th grade, 172 wpm (SD = 24.6) for 8th grade and 180 wpm for the 10th grade (SD = 16.8). There was a significant difference in MRS between school grades (p < 0.001). Participants' reading speed increased by 14.5 wpm (95% CL: 13.1-15.9) with each year of increase in age. We found a significant difference between RA and school grades, but not for CPS. CONCLUSIONS This study provides normative reading performance values for the Portuguese version of the MNREAD chart. The MRS increased with increasing age and school grade, while RA shows initial improvement from early school years and gradually stabilizes in the more mature children. Normative values for the MNREAD test can now be used to determine reading difficulties or slow reading speed in, for example, children with impaired vision.

Abstract
Wildfires have emerged as a global ecological concern due to their wide-ranging off-site effects. One particular consequence is the adverse impact on aquatic environments, as wildfires are acknowledged as a significant source of aquatic contamination through ash runoffs containing toxic compounds. Yet, amphibian response to this source of contamination remains largely undocumented. This study assessed how ash runoffs from Eucalyptus sp. and Pinus sp. affect early aquatic life-stages of Xenopus laevis. Embryos and tadpoles were exposed, respectively, for 96 h and 14 days to serial concentrations (26.9% - 100%) of aqueous extracts of ashes (AEAs; 10 gL-1) composed of eucalypt (ELS) and pine (PLS) ashes. Mortality and development were monitored, and biometric data (snout-to-vent, tail and total length, and weight) measured. Sub-individual endpoints regarding oxidative stress (catalase-CAT; total glutathione-TG; lipid peroxidation-TBARS), neurotoxicity (acetylcholinesterase-AChE), transformation metabolism (glutathione-S-transferase-GST) and energetic metabolism (carbohydrate, lipid and protein content and O2 consumption), were also measured. The two AEAs induced no significant lethal effects on embryos or tadpoles. However, in general, AEAs caused a developmental delay in both life stages. Effects of AEAs on biometric endpoint were only reported for tadpoles, which showed a decreased body length (snout-to-vent, tail and total) and weight (embryos were not weighed), with PLS exerting higher effect than ELS. As for the sub-individual endpoints, embryos showed mostly no alterations on the activity of the monitored parameters, except for PLS, which reduced embryos' carbohydrate content (at ≥59.2%) and increased O2 consumption (at ≥35.0%). Regarding tadpoles, AEA exposure decreased the activity of CAT and GST (at ≥26.0%) and decreased carbohydrate (at ≥26.0%) and lipid (at ≥45.5%), whereas oxygen consumption increased (at ≥26.0%) only on PLS. Overall, the tested AEAs differentially affected amphibians across life-stages, indicating that plant coverage might affect ash toxicity.

Abstract
INTRODUCTION AND OBJECTIVES Sexually transmitted infections are a public health problem affecting 45% of adolescents and young adults worldwide. The evidence suggests that primary care settings are uniquely positioned to provide an opportunity for these preventive interventions. The aim of this project is to improve nurses' interventions for preventing risky sexual behaviors in adolescents attending nursing consultations in a primary healthcare unit. METHODS An audit and feedback were conducted by the JBI Model and Implementation Framework. Five audit criteria representing best practice recommendations for preventing risky sexual behaviors in adolescents were used. Barriers to compliance with the best practices were identified, and strategies were adopted to overcome them. A follow-up audit was conducted using the same approach as the baseline audit. RESULTS Compliance rates improved in four criteria from baseline audit to follow-up audit. CONCLUSION Through auditing and feedback, evidence-based interventions were implemented to prevent sexual risk behavior in adolescents in primary care settings. Further best practice implementation projects should be conducted to improve adolescent health outcomes.

Abstract
BACKGROUND Vaginal birth is a risk factor for weakening of the pelvic floor muscles (PFM) and development of pelvic floor dysfunction (PFD). Perineal tears may decrease PFM function. PFM tone can be assessed with surface EMG (sEMG), but reliability studies of sEMG in women with perineal tears are lacking. The aims of this study were to evaluate test-retest and intrarater reliability of sEMG and compare PFM activation between nulliparous and primiparous. METHODS A sEMG test-retest was performed in 21 women (12 nulliparous and 9 primiparous with grade II tears) to assess intra-rater reliability during rest and maximal voluntary contraction (MVC) of the PFM. Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) were tested. A comparison between nulliparous' and primiparous' PFM activation during rest and MVC was performed. RESULTS sEMG demonstrated fair reliability in nulliparous (ICC: 0.239; SEM: 5.2; MDC: 14.5) and moderate reliability in primiparous (ICC: 0.409; SEM: 1.5; MDC: 4.2) during rest. For peak MVC very good intrarater reliability was found in nulliparous (ICC: 0.92; SEM: 8.0; MDC: 22.2) and in primiparous (ICC: 0.823; SEM: 8.0; MDC: 22.2). Statistically significant lower PFM activation was found in primiparous women with perineal tear grade II than in nulliparous at rest (mean difference 9.1 µV, 95% confidence interval [CI] 3.0-19.0, p = 0.001), and during MVCpeak (mean difference 50.0 µV, 95% CI 10.0-120.0 p = 0.021). CONCLUSIONS sEMG is reliable when measuring PFM activation in primiparous women with perineal tears grade II. Women with perineal tears grade II have lower PFM activation both during rest and MVC.

Abstract
Dysfunction in key cellular organelles has been linked to diabetic complications. This study intended to investigate the alterations in the unfolded protein response (UPR), autophagy, and mitochondrial function, which are part of the endoplasmic reticulum (ER) stress response, in wound healing (WH) under diabetes conditions. WH mouse models were used to evaluate the UPR, autophagy, mitochondrial fusion, fission, and biogenesis as well as mitophagy in the skin of control and diabetic mice at baseline and 10 days after wounding. The autophagic flux in response to high-glucose conditions was also evaluated in keratinocyte and fibroblast cell cultures. WH was impaired in the diabetic mouse model, and we found that the UPR and autophagy pathways were activated in skin wounds of control mice and in the non-wounded skin of diabetic mice. Moreover, high-glucose conditions induced autophagy in the keratinocyte and fibroblast cell cultures. However, mitophagy did not change in the skin of diabetic mice or the wounded skin. In addition, mitochondrial fusion was activated in control but not in the skin wounds of diabetic mice, while mitochondrial biogenesis is downregulated in the skin of diabetic mice. In conclusion, the activation of the UPR, autophagy, and mitochondrial remodeling are crucial for a proper WH. These results suggest that the increase in ER stress and autophagy in the skin of diabetic mice at baseline significantly escalated to pathological levels after wounding, contributing to impaired WH in diabetes.

Abstract
This work aimed to study NiO/F-TiO2 composites in the photocatalytic degradation of 4-chlorophenol. F-TiO2 support was prepared by in-situ fluorination of TiO2 using the sol-gel method. The heterostructured materials were prepared by wet impregnation method, varying NiO content (0.5, 1.0, and 2.0% wt). The solids were characterized by X-ray fluorescence, X-ray diffraction, nitrogen physisorption, diffuse reflectance UV-Vis spectrophotometry, infrared spectroscopy, and X-ray photoelectron spectroscopy. The characterization studies showed that the coupling of TiO2 with fluoride ions promoted the generation of ≡Ti-F surface species that could be responsible for the decrease in the recombination frequency of charge carriers and the increased photoactivity. In addition, it was found that the coupling of NiO/F-TiO2 semiconductors improved the photocatalytic properties of the fluorinated support, obtaining higher percentages of degradation and mineralization of the phenolic contaminant. These results are possibly a consequence of factors such as the formation of larger crystallites, lower band gap energies, and the generation of p-n type interfacial heterojunctions that potentiate the proper separation of electron-hole pairs. An effect of NiO content on photoactivity was observed, being a percentage of 1.0% wt the optimum in this photocatalytic treatment.

Abstract
Oral hygiene has been shown to reduce adverse events and promote the quality of life of patients with stroke. However, a stroke can result in the impairment of physical, sensory, and cognitive abilities, and comprise self-care. Although nurses recognize its benefits, there are areas for improvement in the implementation of the best evidence-based recommendations. The aim is to promote compliance with the best evidence-based recommendations on oral hygiene in patients with stroke. This project will follow the JBI Evidence Implementation approach. The JBI Practical Application of Clinical Evidence System (JBI PACES) and the Getting Research into Practice (GRiP) audit and feedback tool will be used. The implementation process will be divided into three phases: (i) establishing a project team and undertaking the baseline audit; (ii) providing feedback to the healthcare team, identifying barriers to the implementation of best practices, and co-designing and implementing strategies using GRIP, and (iii) undertaking a follow-up audit to assess the outcomes and plan for sustainability. So, the successful adoption of the best evidence-based recommendations on oral hygiene in patients with stroke will reduce the adverse events related to poor oral care and may improve patients' quality of care. This implementation project has great transferability potential to other contexts.

Abstract
Footwear with or without custom foot orthotics have the potential to improve comfort, but the link with running performance needs further investigation. We systematically reviewed the association of footwear comfort on running economy in recreational runners. Nine electronic databases were searched from inception to March 2020. Eligible studies investigated both direct outcome measures of running performance (e.g. running speed) and/or physiological measures (e.g. running economy (RE)) alongside comfort for each footwear condition tested. Methodological quality was assessed using the "Effective Public Health Practice Project" (EPHPP). RE during submaximal running was the most common physiological outcome reported in 4 of the 6 eligible studies. The absolute difference in RE between the most and least comfortable footwear condition was computed, and meta-analysis was conducted using a random effect model. The most comfortable footwear is associated with a reduction in oxygen consumption (MD: -2.06 mL.kg-1.min-1, 95%CI: -3.71, -0.42, P = 0.01) while running at a set submaximal speed. There was no significant heterogeneity (I2 = 0%, P = 0.82). EPHPP quality assessment demonstrated weak quality of the studies, due to reporting bias and failing to disclose the psychometric properties of the outcome measures. It can be concluded with moderate certainty that improved RE in recreational athletes is associated with wearing more comfortable footwear compared to less comfortable footwear.HighlightsThis systematic review reports on the association of footwear comfort with running economy in recreational runners.Running economy during constant submaximal running is likely improved in recreational runners wearing more comfortable compared to less comfortable footwear.This finding is based on a meta-analysis, including four studies, showing a small but statistically significant decreased oxygen consumption at steady state speeds while wearing the most comfortable footwear.

Abstract
BACKGROUND Introducing a de-novo home haemodialysis (HHD) program often raises safety concerns as errors could potentially lead to serious adverse events. Despite the complexity of performing haemodialysis at home without the supervision of healthcare staff, HHD has a good safety record. We aim to pre-emptively identify and reduce the risks to our new HHD program by risk assessment and using failure mode and effects analysis (FMEA) to identify potential defects in the design and planning of HHD. METHODS We performed a general risk assessment of failure during transitioning from in-centre to HHD with a failure mode and effects analysis focused on the highest areas of failure. We collaborated with key team members from a well-established HHD program and one HHD patient. Risk assessment was conducted separately and then through video conference meetings for joint deliberation. We listed all key processes, sub-processes, step and then identified failure mode by scoring based on risk priority numbers. Solutions were then designed to eliminate and mitigate risk. RESULTS Transitioning to HHD was found to have the highest risk of failure with 3 main processes and 34 steps. We identified a total of 59 areas with potential failures. The median and mean risk priority number (RPN) scores from failure mode effect analysis were 5 and 38, with the highest RPN related to vascular access at 256. As many failure modes with high RPN scores were related to vascular access, we focussed on FMEA by identifying the risk mitigation strategies and possible solutions in all 9 areas in access-related medical emergencies in a bundled- approach. We discussed, the risk reduction areas of setting up HHD and how to address incidents that occurred and those not preventable. CONCLUSIONS We developed a safety framework for a de-novo HHD program by performing FMEA in high-risk areas. The involvement of two teams with different clinical experience for HHD allowed us to successfully pre-emptively identify risks and develop solutions.

Abstract
Abstract
Background
Aortic stenosis (AS) is one of the main valvular heart diseases in developed countries. Degenerative fibrocalcific aortic stenosis is a progressive disease of the valve and ultimately of the myocardium, which can be fatal when symptomatic. There is no medical treatment that can halt or delay its progression. AS does not evolve linearly over time, and not every patient has the same progression rate.
Aims
The aim of this study is to 1) compare different mathematical models of aortic stenosis progression, 2) cluster patients into rapid and slow progressors and explore possible predictors, 4) evaluate the impact of different progression rates on cardiac structure and function, and 5) evaluate survival and optimal timing for follow-up and treatment.
Methods
We retrospectively studied consecutive patients with aortic peak velocities from 2012 to 2020. Follow-up echocardiograms, seriated biomarker assessment, and clinical records were consulted, providing a multiparametric data frame for longitudinal and dynamic modeling of aortic stenosis progression and its consequences.
Results
This study included 9583 studies from 752 patients with a median total follow-up of 4.26 years (interquartile range: 1.28 to 7.24 years). A logistic model was selected with the best accuracy to predict the rate of AS progression. Patients were categorized into slow and rapid progressors in a ratio of 5:1. Multiparametric analysis showed no association between these profiles and clinical variables. However, anti-hypertensive drugs before and after adjustment for blood pressure control (Calcium Channel Blockers, p=0.013, OR 0.50) were associated with slower progression. Meanwhile, elevated inflammatory markers (erythrocyte sedimentation rate, p=0.01) were associated with faster AS progression. Despite no survival difference between these groups, higher rates of valvular intervention were registered in rapid progressors (p<0.001). Moreover, faster progressors were associated with earlier cardiac damage (as demonstrated by early onset of moderate mitral and tricuspid valve regurgitation, left auricle dilation, and left ventricle hypertrophy, p<0.05).
Conclusions
These results can potentially modify follow-up times and deliver more personalized and individualized health care to different AS patients, thereby optimizing resources.

Abstract
Introduction Thoracic perivascular adipose tissue (tPVAT) has a phenotype resembling brown AT. Dysfunctional tPVAT appears to be linked to vascular dysfunction. Methods We evaluated uncoupling protein 1 (UCP1) expression by Western blot, oxidative stress by measuring lipid peroxidation, the antioxidant capacity by HPLC and spectrophotometry, and mitochondrial respiration by high-resolution respirometry (HRR) in tPVAT, compared to inguinal white AT (iWAT), obtained from non-diabetic (NDM) and streptozocin-induced diabetic (STZ-DM) mice. Mitochondrial respiration was assessed by HRR using protocol 1: complex I and II oxidative phosphorylation (OXPHOS) and protocol 2: fatty acid oxidation (FAO) OXPHOS. OXPHOS capacity in tPVAT was also evaluated after UCP1 inhibition by guanosine 5'-diphosphate (GDP). Results UCP1 expression was higher in tPVAT when compared with iWAT in both NDM and STZ-DM mice. The malondialdehyde concentration was elevated in tPVAT from STZ-DM compared to NDM mice. Glutathione peroxidase and reductase activities, as well as reduced glutathione levels, were not different between tPVAT from NDM and STZ-DM mice but were lower compared to iWAT of STZ-DM mice. OXPHOS capacity of tPVAT was significantly decreased after UCP1 inhibition by GDP in protocol 1. While there were no differences in the OXPHOS capacity between NDM and STZ-DM mice in protocol 1, it was increased in STZ-DM compared to NDM mice in protocol 2. Moreover, complex II- and FAO-linked respiration were elevated in STZ-DM mice under UCP1 inhibition. Conclusions Pharmacological therapies could be targeted to modulate UCP1 activity with a significant impact in the uncoupling of mitochondrial bioenergetics in tPVAT.

Abstract
OBJECTIVE The aim of the study was to investigate sleep characteristics, use of supplements, and training volume of recreational triathletes, and to verify possible associations with perceived performance drops and occurrence of injuries. MATERIALS AND METHODS Recreational triathletes (n=942) answered a questionnaire inquiring about their demographic characteristics, performance, injuries and training volume. RESULTS When comparing athletes who slept more (9-10 hours) with those who slept less, less sleep was associated with a higher prevalence of perceived performance drops. Regarding difficulties in initiating sleep, the absence of initiating difficulties (p<0.001) was a protective factor against perceived performance drops. Regarding weekly training volume, compared to those who trained more than 20 hours, training less than 3 hours (p<0.001), 3-5 hours (p<0.001), or 12-14 hours (p<0.001) were protective factors against perceived performance drops. Concerning training volume and injuries, we found that compared to those who trained more than 20 hours, training 18-20 hours (p<0.001), 15-17 hours (p<0.001), 12-14 hours (p<0.001), 6-8 hours (p<0.001), or 3-5 hours (p<0.001) were protective factors against injuries. CONCLUSIONS Triathletes with a lower sleep quantity and those who have difficulties initiating sleep frequently experience drops in performance. Training volumes can influence both performance and the likelihood of injuries.

Abstract
BackgroundJuvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and adolescents [1]. The manifestation of JIA may include joint swelling, tenderness, and painful limitation with joint movement. Only few studies have explored the effect of foot orthoses (FOs) alone in children with JIA [2,3]. These studies showed FOs can reduce pain in children with JIA, however, further research with larger sample sizes and longer follow-ups are needed [4]. Prescribing FOs on the same day of the initial assessment may promote early clinical and targeted intervention, which is the gold standard approach in paediatric rheumatology.ObjectivesThis single blinded multicentre randomised clinical trial (RCT) aims to investigate the effect of customised prefabricated FOs in reducing pain amongst children and adolescents with JIA.MethodsOverall, 66 children and adolescents with JIA presenting with foot symptoms were recruited from the Sydney Children’s Hospitals Network (Westmead and Randwick) and John Hunter Children’s Hospital (Newcastle). The primary outcome measure was pain with a minimal clinical significance of 8mm on the visual analogue scale (VAS). Participants were randomly allocated to receive either customised prefabricated or sham FOs. The trial intervention was a low-density Slimflex Simple device that was customised at chair-side. The control (sham) device was made of 2mm flat leather board with no corrective modifications. Standardised tests such as the Foot Posture Index, navicular drift and drop were used to identify biomechanical abnormalities. The FOs were worn for a total of 12 months, with data collected at baseline, 4 weeks, 3, 6 months and 12 months.ResultsReduction in self-reported pain was statistically and clinically significant at 4-weeks (p=0.018, -14.92 [-27.30, -2.55]) and 3 months (p=<0.001, -28.93 [-40.90, -16.96]) post intervention in favour of the trial group. The 6- and 12-month follow-ups were not statistically or clinically significant. Parent reported pain was statistically and clinically significant at the 3-month (p=<0.001, -21.92 [-33.16, -10.67]) in the reduction of pain in favour of the trial group. However, parent reported pain was not statistically significant at the 4-week, 6- and 12- month follow-ups. These results are similar to child reported pain with a p-value of less than 0.001 and average coefficients twice that of the clinical significance cut-off for VAS pain in paediatric rheumatology. The trial intervention was safe and tolerated well by participants with high compliance and adherence rates.ConclusionResults of this clinical trial indicate customised preformed FOs can be effective in reducing pain and in children with JIA experiencing foot and ankle symptoms. Significant clinical effects appear to be within the first 3-months of intervention prescription and reduce beyond 6 months. Overall, this podiatric intervention was safe, inexpensive, well tolerated and it can be easily implemented as part of the multidisciplinary paediatric rheumatology care.References[1]Ravelli A, Martini A.

Abstract
Adipose tissue expansion and subsequent metabolic dysfunction has been considered one of the major risk factors for development of cardiometabolic disease. Epicardial adipose tissue (EAT) in particular is a unique subtype of visceral adipose tissue located on the surface of the heart, around the coronary arteries. Due to its proximity, EAT can modulate the local metabolic and immune function of cardiomyocytes and coronary arteries. Several microRNAs have been described as key players in both cardiac and vascular function that when dysregulated will contribute to dysfunction. Here we review the influence of obesity in the crosstalk between specific adipose tissue types, in particular the EAT-secreted microRNAs, as key modulators of cardiac disease progression, not only as early biomarkers but also as therapeutic targets for cardiometabolic disease.

Abstract
Copper (Cu) is an essential element for organism's metabolism, being controversially listed as a priority pollutant. Importantly, the toxicity of Cu has been linked to several cell death pathways. Thus, this study aimed to assess if macroautophagic pathways are triggered by Cu in zebrafish gill, the main target of waterborne pollutants. The electron microscopy findings indicated that Cu induced profound impacts on zebrafish gill structure and functions, being this tissue a biomarker sensitive enough to indicate early toxic effects. The findings also support a clear impairment of autophagy, througth the absence of phagossomes and the significant down-regulation mRNA transcript levels of microtubule-associated protein light chain 3 (LC3). The reduction of LC3 levels was often associated to an increase of apoptotic activation, indicating that the inhibition of macroautophagy triggers apoptosis in zebrafish gills. This study highlighted that the autophagic down-regulation might be affected through the activation of other cell death signaling pathway.

Abstract
Literature suggests that acceptance and commitment therapy (ACT) is effective in improving well-being and in reducing psychopathological symptoms commonly experienced by people with chronic illness (CI). Compassion-focused therapy (CFT) reduces psychological distress, especially in individuals with high levels of shame and self-criticism, but few studies have explored CFT in CI. Additionally, studies almost exclusively compared ACT and CFT with inactive controls (wait-list; treatment as usual). Also, there is an interest in developing cost-effective mental health solutions, such as low-intensity online psychological interventions. This randomized controlled trial (RCT) aimed to assess the acceptability and compare the efficacy of four-session online ACT (n = 25) and CFT (n = 24) interventions in a sample of people with CI. Results showed both interventions were acceptable, with attrition rates at post-intervention comparable to those found in similar studies (around 50%). Intention-to-treat analyses showed that participants presented significantly less illness-related shame, less uncompassionate self-responding and more valued living after the intervention, although no difference was found between conditions. Results were sustained at 3- and 6-month follow-up. Results did not find statistical differences between conditions through reliable change index (RCI). Correlation between demographics and RCI showed that, at post-intervention, younger participants presented more behavioural awareness, men presented more valued action, and participants with CI for shorter periods presented less uncompassionate self-responding and less anxiety. Results suggest that low-intensity (four sessions) online ACT and CFT are cost-effective approaches to promote mental health of individuals with CI. Results and limitations are thoroughly discussed.

Abstract
OBJECTIVES V30M in transthyretin (TTR) gene is causative for hereditary ATTRv amyloidosis (familial amyloid polyneuropathy). ATTRv amyloidosis shows a wide variation in age-at-onset (AO) between clusters, families, and among generations. We aim at identifying genetic modifiers of disease onset that may contribute to this variability in Portuguese patients by identifying other variants in TTR locus, beyond the ATTRv amyloidosis causing variant that could play a regulatory role in its expression level. METHODS We analysed DNA samples of 330 ATTRV30M carriers (299 patients, 31 aged-asymptomatic carriers aged >40 years) from 120 families currently under follow-up. A generalised estimating equation analysis (GEE) was used to take into account non-independency of AO between relatives. An intensive in silico analysis was performed in order to understand a possible regulation of gene expression. RESULTS We found 11 rare variants in the promoter, coding and intron/exon boundaries of the TTR gene associated with the onset of symptoms before and after age 40 years, namely 2 novel ones and a tandem CA-dinucleotide repeat. Furthermore, of the 4 common variants found, one was significantly associated with AO and may influence the constitutive splicing of TTR pre-mRNA. The seven ATTRV30M/V30M homozygous do not carry any of the variants identified in this study, including the common ones. In silico analysis disclosed significant alterations in the mechanism of splicing, transcription factors and miRNAs binding. CONCLUSIONS Variants within the promoter region may modify disease expressivity and variants in the 3'UTR can impact the efficacy of novel therapeutic interventions. Importantly, the putative mechanisms of regulation of gene expression within the TTR gene deserve to be better explored, in order to be used in the future as potential therapeutical targets.

Abstract
Congenital ataxias are a heterogeneous group of disorders characterized by congenital or early-onset ataxia. Here, we describe two siblings with congenital ataxia, who acquired independent gait by age 4 years. After 16 years of follow-up they presented near normal cognition, cerebellar ataxia, mild pyramidal signs, and dystonia. On exome sequencing, a novel homozygous variant (c.1580-18C > G - intron 17) in ATP8A2 was identified. A new acceptor splice site was predicted by bioinformatics tools, and functionally characterized through a minigene assay. Minigene constructs were generated by PCR-amplification of genomic sequences surrounding the variant of interest and cloning into the pCMVdi vector. Altered splicing was evaluated by expressing these constructs in HEK293T cells. The construct with the c.1580-18C > G homozygous variant produced an aberrant transcript, leading to retention of 17 bp of intron 17, by the use of an alternative acceptor splice site, resulting in a premature stop codon by insertion of four amino acids. These results allowed us to establish this as a disease-causing variant and expand ATP8A2-related disorders to include less severe forms of congenital ataxia.

Abstract
Several lines of evidence suggest the existence in the eukaryotic cells of a tight, yet largely unexplored, connection between DNA replication and sister chromatid cohesion. Tethering of newly duplicated chromatids is mediated by cohesin, an evolutionarily conserved hetero-tetrameric protein complex that has a ring-like structure and is believed to encircle DNA. Cohesin is loaded onto chromatin in telophase/G1 and converted into a cohesive state during the subsequent S phase, a process known as cohesion establishment. Many studies have revealed that down-regulation of a number of DNA replication factors gives rise to chromosomal cohesion defects, suggesting that they play critical roles in cohesion establishment. Conversely, loss of cohesin subunits (and/or regulators) has been found to alter DNA replication fork dynamics. A critical step of the cohesion establishment process consists in cohesin acetylation, a modification accomplished by dedicated acetyltransferases that operate at the replication forks. Defects in cohesion establishment give rise to chromosome mis-segregation and aneuploidy, phenotypes frequently observed in pre-cancerous and cancerous cells. Herein, we will review our present knowledge of the molecular mechanisms underlying the functional link between DNA replication and cohesion establishment, a phenomenon that is unique to the eukaryotic organisms.

Abstract
Warsaw breakage syndrome (WABS) is a genetic disorder characterized by sister chromatid cohesion defects, growth retardation, microcephaly, hearing loss and other variable clinical manifestations. WABS is due to biallelic mutations of the gene coding for the super-family 2 DNA helicase DDX11/ChlR1, orthologous to the yeast chromosome loss protein 1 (Chl1). WABS is classified in the group of "cohesinopathies", rare hereditary diseases that are caused by mutations in genes coding for subunits of the cohesin complex or protein factors having regulatory roles in the sister chromatid cohesion process. In fact, among the cohesion regulators, an important player is DDX11, which is believed to be important for the functional coupling of DNA synthesis and cohesion establishment at the replication forks. Here, we will review what is known about the molecular and cellular functions of human DDX11 and its role in WABS etiopathogenesis, even in light of recent findings on the role of cohesin and its regulator network in promoting chromatin loop formation and regulating chromatin spatial organization.

Abstract
Abstract
Background
The Homeless People is marked by serious social vulnerability, related to the absence of human dignity. Requirements of personal and residential documents, reception and inadequate approaches are barriers to access these people. The creation of Street Medical Consultation (CnaR), based on the logic of harm reduction in association with the other services, is a strategy that seeks to expand access to the services of the Public Healthcare System (SUS) in Brazil. The research aimed to analyze the characteristics and vulnerabilities of this population, the performance of CnaR and its articulation with services from the health care and the social assistance care network.
Methods
Study of a qualitative approach using 8 semi-structured interviews and the Thematic Content Analysis method. The study scenario was the CnaR multiprofissional team in a city in the interior of São Paulo.
Results
Three categories were found: (1) Population in Street Situation - complexity of those who live on the street: prejudices, violence and barriers in society and health institutions constitute a process of invisibility. (2) CnaR's work in the perspective of harm reduction: it is organized to meet the clinical and alcohol and other drugs demands through fixed fields, mobile fields and team meeting. (3) Beyond CnaR - network relationships: bringing dynamics to relationships, being strengthened or weakened. Ignorance of the service and their performance also generates CnaR invisibility process. The strategies developed include coping, dialogue, building partnerships and the process of visibility and fighting for the rights of the Homeless Persons.
Conclusions
CnaR finds itself as an insufficient service to meet all the demands of this vulnerable population in isolation, needing the network to expand access to health and other goods. It is necessary to combat prejudice against this population among health professionals and develop more efficient intersectoral articulation.
Key messages
The Homeless People have serious vulnerability and need humanization, guaranteeing equity in assistance in all sectors of society, especially the health care and the social assistance. The Street Medical Consultation faces performance difficulties to guarantee access to the Homeless People within the intersectoral network, often being the sole responsible for this population.

Abstract
Abstract
Introduction
Carnival is a popular festival that was introduced in Brazil from the European heritage. However, it was the enslaved African people who saw forms and processes of resistance for the construction of identity during this festive period. The reframing and resistance that blacks establish with carnival is the result of a cultural need to stay alive both as a subject and as a collective. This is how samba schools emerge in the urban peripheries of Rio de Janeiro as a form of artistic, cultural and leisure production. Associations acquire for themselves the role of the State in providing access to rights that many are denied, neglected or scrapped. In these schools, it is possible to observe a relationship of belonging and donation (”principle of gift”) on the part of their so-called community, they are passions and meanings that produce relationships of self-care reaffirmation of intersubjectivity.
Objective
This work aims to identify the carnival as a space for the production of projects, resistances and protagonisms and to analyze the meanings of the subjective processes of health, disease, care and carnival, through the narratives of a samba school community.
Methodology
This is an exploratory analysis of a qualitative approach in public health. A samba school was chosen from the special group of the capixaba carnival, which is located in a peripheral region. We will use it to define snowball technical sampling. The data will be collected through semi-structured interviews and on-site observations by the researcher. The data analysis methodology used will be discourse analysis.
Expected Results
It is expected to understand the different practices and processes of health, disease, care and carnival, among a peripheral community that is part of a samba school.
Key messages
This work aims to analyze health care about a cultural aspect of marginalized populations and how health policies are related to carnival. Impact on the production of knowledge about popular culture and health.

Abstract
Objective
To know the dynamic processes that involve the production of care for women in situations of violence.
Methods
Study of qualitative approach and cartographic inspiration based on the theoretical reference of Institutionalism that had as scenario a reference center for women in domestic violence located in Espírito Santo, Brazil. Six professionals who worked directly in the care of women participated in the research. Interventions were carried out, through seven workshops, using storytelling. The material production tools were narratives, the researcher's field diary and the collective field diary, which was built from the record and observation of all the participants in the study. The workshops were held at the center according to the availability of participants and lasted an average of 60 minutes. The meetings were recorded and later transcribed together with the notes of the field diaries, seeking, through a cartography, to give meaning to the experiences lived by the participants. Through the analysis of implication, it was possible to give visibility to the various relationships that constitute a certain reality, in which the researcher is involved.
Results
The study pointed out that violence crosses all women influencing the production of care offered by professionals at the reference center. The narratives multiplied senses contributing to the problematization of the care offered, providing the qualification of other ways of thinking/acting in health.
Conclusions
From an ethical-aesthetic-political paradigm it is possible to produce reflections that broaden the view of care for women in violent situations beyond biological issues, contributing with desirable productive processes in the prevention of violence and the promotion of health.
Key messages
It gives visibility to micropolitical processes and contributes to the construction of policies for women's health capable of welcoming differences and singularities. It shows innovation for the field of qualitative health research, broadening the view on the care of women in situations of violence beyond biological issues.

Abstract
Abstract
Background
A qualitative and exploratory study that analyzed the perspective of access to Integrative and Complementary Practices in Health (PICS) by listening users from a selected service of primary care of a municipality.
Objective
Analyze the access to PICS in a health public service of a municipality in a state of Brazil, from the perspective of users, as well as aimed at understand the needs and desires of health care these users in the search process and use of PICS, identifying facilitators and barriers in this trajectory.
Methods
The theoretical reference from Frenk on access was used, which systematizes the flow of events at the moment when the health need is perceived until the effectiveness of the care, besides the demand and entrance in the health services and the continuity of the treatment. The data collection was done by participant observation and semi-structured interview with 29 users of the service. The narratives were worked through the analysis of thematic content.
Results
The results indicated two groups of PICS: complex medical systems and therapeutic resources. There were differences in the organization of the offer with consequent influence on the different forms of access. It was registered the interest for the use of health care in a non-biomedical logic and a re-signification of the health-disease process in PICS users, contributing to the continuity of health production.
Conclusions
It was concluded that the current models of access analysis do not contemplate the diversities of access to the PICS, and the various possibilities of encounters with these practices allow the identification of the marginality of this care in all cases analyzed.
Key messages
Integrative and Complementary Health Practices gain national relevance as they contribute to the development of health promoting activities, focus on the individual, prevention and comprehensive care. However, considered a controversial topic in a hegemonically biomedical scenario, the incorporation of these new knowledge and practices in the health field occurs in a marginal way.

Abstract
Abstract
Introduction The excessive consumption of sodium is one of the main problems in public health and responsible for the loss of years of a healthy life. The salt added to the meals represents a large part of the salt ingested, and the collaborators/cooks responsible for its addition need careful analysis, and intervention adjusted to the analysed reality, its salt consumption and its perception of saltiness may influence the amount of salt added.
Objectives This study had as main objective to perceive the relationship between the perception of salt of the employees of the Food and Nutrition Unit and the amount of salt added in the meals that were confectioned.
Methodology An observational, analytical, cross-sectional study was conducted, in which 6 selected cooks from the IPSS’s of Águeda participated. In order to estimate the amount of salt added to the meals, 20 samples of meals prepared by the cooks were taken, and a quantitative assessment of average salt per meal was made using Flame Photometry. The cooks were also subjected to two taste sensitivity tests. The data treatment was performed using the statistical software SPSS, and a statistical significance level of 5% was considered.
Results A better perception of the salty taste was observed in the cooks of Institution B. Although there were no differences with statistical significance in the quantity of salt of the meals between the two institutions, the mean and maximum addition of salt in the cooked meals was higher in institution B, regardless of the cook evaluated.
Conclusion The perception of the salty taste of the cooks does not seem to determine the amount of salt added to the meals.

Abstract
Catharanthus roseus (Apocynaceae family) extract is rich in organic phytochemicals such as alkaloids, polyphenolic compounds, and flavonoids. It contains several functional entities such as fused heterocycles, and hydroxyl and carbonyl groups, which could be useful for corrosion inhibition of mild steel in NaCl environments. In the present work, ultrasonic energy was used to obtain the ethanolic extracts of root and stem which were then tested as corrosion inhibitors for mild steel in the presence of 3.5% NaCl. The corrosion inhibition process was studied by UV-visible spectroscopy, Fourier transform infrared spectroscopy, atomic force microscopy, weight loss, and electrochemical methods. After immersing in the corrosive medium, the microstructures of mild steel were investigated by scanning electron microscopy, X-ray diffraction, and ellipsometry. The extract of C. roseus showed excellent adsorption on mild steel surface as confirmed by DFT calculations. The results indicate that the extract of C. roseus acts as a mixed type corrosion inhibitor, where the stem extract is the most efficient inhibitor in 3.5% NaCl solution possibly due to the higher active area of stem phytochemicals. C. roseus phytochemicals are physisorbed on the 111 Fe surface, and the oxygen non-bonding electron chemisorbed on the polarized state 111 Fe surface.![]()

Abstract
Objectives Transthyretin (TTR) familial amyloid polyneuropathy (FAP) (OMIM 176300) shows a variable age‐at‐onset (AO), including within families. We hypothesized that variants in C1QA and C1QC genes, might also act as genetic modifiers of AO in TTR‐FAP Val30Met Portuguese patients. Methods We analyzed DNA samples of 267 patients (117 families). To search for variants, all exons and flanking regions were genotyped by automated sequencing. We used generalized estimating equations (GEEs) to take into account the non‐independency of AO among relatives. Intensive in silico analyses were performed, using various software to assess miRNAs target sites, splicing sites, transcription factor binding sites alterations, and gene–gene interactions. Results Two variants for C1QA gene, GA genotype of rs201693493 (P < 0.001) and CT genotype of rs149050968 (P < 0.001), were significantly associated with later AO. In silico analysis demonstrated, that rs201693493 may alter splicing activity. Regarding C1QC, we found three statistically significant results: GA genotype of rs2935537 (P = 0.003), GA genotype of rs201241346 (P < 0.001) and GA genotype of rs200952686 (P < 0.001). The first two were associated with earlier AO, whereas the third was associated with later‐onset. Interpretation C1QA was associated with later onset, whereas C1QC may have a double role: variants may confer earlier or later AO. As found in a study in Cyprus, we confirmed the role of complement C1Q genes (and thus of inflammation) as modulator of AO in Portuguese patients with TTR‐FAP Val30Met.

The purpose of this work was to assess if patients with AD present a specific cerebrospinal fluid (CSF) cytokine profile and if it correlates to disease progression. We determined the levels of 27 cytokines in CSF of patients with AD and compared them with patients with frontotemporal dementia and nondemented controls. In addition, we correlated the cytokine levels with cognitive status and disease progression after 12 months. Patients with AD had higher levels of proinflammatory and anti-inflammatory cytokines (eotaxin, interleukin [IL]-1ra, IL-4, IL-7, IL-8, IL-9, IL-10, IL-15, granulocyte colony-stimulating factor, monocyte chemotactic protein 1, platelet-derived growth factor, tumor necrosis factor alfa) compared to nondemented controls. There was a negative correlation between the disease progression and the levels of several cytokines (IL-1β, IL-4, IL-6, IL-9, IL-17A, basic fibroblast growth factor, granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, interferon gamma, macrophage inflammatory proteins-1β). To the best of our knowledge, this is the first study reporting a "protective" role of the upregulation of specific intrathecal cytokine levels in AD. This finding supports that a fine "rebalancing" of the immune system represents a new target in AD therapeutic approach.

Abstract
Protein post-translational modifications (PTMs) that potentiate protein aggregation have been implicated in several neurological disorders, including Alzheimer's (AD) and Parkinson's disease (PD). In fact, Tau and alpha-synuclein (ASYN) undergo several PTMs potentiating their aggregation and neurotoxicity. Recent data posits a role for acetylation in Tau and ASYN aggregation. Herein we aimed to clarify the role of Sirtuin-2 (SIRT2) and HDAC6 tubulin deacetylases as well as p300 acetyltransferase in AD and PD neurodegeneration. We used transmitochondrial cybrids that recapitulate pathogenic alterations observed in sporadic PD and AD patient brains and ASYN and Tau cellular models. We confirmed that Tau protein and ASYN are microtubules (MTs)-associated proteins (MAPs). Moreover, our results suggest that α-tubulin acetylation induced by SIRT2 inhibition is functionally associated with the improvement of MT dynamic determined by decreased Tau phosphorylation and by increased Tau/tubulin and ASYN/tubulin binding. Our data provide a strong evidence for a functional role of tubulin and MAPs acetylation on autophagic vesicular traffic and cargo clearance. Additionally, we showed that an accumulation of ASYN oligomers imbalance mitochondrial dynamics, which further compromise autophagy. We also demonstrated that an increase in Tau acetylation is associated with Tau phosphorylation. We found that p300, HDAC6 and SIRT2 influences Tau phosphorylation and autophagic flux in AD. In addition, we demonstrated that p300 and HDAC6 modulate Tau and Tubulin acetylation. Overall, our data disclose the role of Tau and ASYN modifications through acetylation in AD and PD pathology, respectively. Moreover, this study indicates that MTs can be a promising therapeutic target in the field of neurodegenerative disorders in which intracellular transport is altered.
