Abstract
DNA vaccines can be a potential solution to protect global health, triggering both humoral and cellular immune responses. DNA vaccines are valuable in preventing intracellular pathogen infections, and therefore can be explored against coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2). This work explored different systems based on polyethylenimine (PEI), functionalized for the first time with both cholesterol (CHOL) and mannose (MAN) to deliver parental plasmid (PP) and minicircle DNA (mcDNA) vectors encoding the receptor-binding domain (RBD) of SARS-CoV-2 to antigen-presenting cells (APCs). For comparative purposes, three different systems were evaluated: PEI, PEI-CHOL and PEI-CHOL-MAN. The systems were prepared at various nitrogen-to-phosphate group (N/P) ratios and characterized in terms of encapsulation efficiency, surface charge, size, polydispersity index (PDI), morphology, and stability over time. Moreover, in vitro transfection studies of dendritic cells (JAWS II) and human fibroblast cells were performed. Viability studies assured the biocompatibility of all nanocarriers. Confocal microscopy studies confirmed intracellular localization of systems, resulting in enhanced cellular uptake using PEI-CHOL and PEI-CHOL-MAN systems when compared with the PEI system. Regarding the RBD expression, PEI-CHOL-MAN was the system that led to the highest levels of transcripts and protein expression in JAWS II cells. Furthermore, the nanosystems significantly stimulated pro-inflammatory cytokines production and dendritic cell maturation in vitro. Overall, mannosylated systems can be considered a valuable tool in the delivery of plasmid DNA or mcDNA vaccines to APCs.

Abstract
AIM Acromegaly is a rare chronic disease, caused by the over-secretion of growth hormone (GH), that creates a pro-inflammatory state, but the exact mechanisms by which GH or insulin-like growth factor 1 (IGF-1) act on inflammatory cells are not fully understood. Aim of the study was to evaluate Interleukin-33 (IL33) and the skin perfusion of hands in patients with acromegaly (AP) and healthy controls (HC). METHODS IL33 have been assessed in 40 AP and 40 HC. IL 33 was determined and skin perfusion of hands was assessed by laser speckle contrast analysis (LASCA) in both populations. RESULTS IL33 was significantly higher in AP compared to HC [45.72 pg/ml (IQR 28.74-60.86) vs 14 pg/ml (IQR 6.5535); p < 0.05]. At LASCA, peripheral blood perfusion (PBP) was significantly lower in AP compared to HC [53.39 pU (IQR 40.94-65.44) vs 87 pU (IQR 80-98) p < 0.001]. The median values of ROI1, ROI2 and ROI3 were significantly lower in AP compared to HC [97.32 pU (IQR 50.89-121.69) vs 131 pU (IQR 108-135); p < 0.001], [58.68 pU (IQR 37.72-84.92) vs 83 pU (IQR 70-89), p < 0.05] and HC [52.16 (34.47-73.78) vs 85 (78-98), p < 0.001], respectively. The proximal-distal gradient (PDG) was observed in 18 of 40 (45%) AP. CONCLUSION Serum IL33 is higher in AP compared to HC; conversely a reduction of PBP of hands was present in AP compared to HC, probably due to endothelial dysfunction, strictly dependent on acromegaly and are not influenced by the choice of treatment.

Abstract
Contact Lens Discomfort (CLD) is the main cause in contact lens (CLs) discontinuation, referred in literature as drop-out phenomenon. Despite such evidence was reported in several clinical studies, a relationship between physico-chemical properties of CLs and CLD is not still totally understood. In this regard, the friction of CLs surfaces seems to be related to discomfort feeling events, probably due to an alteration of the lubricate function of the tear film after the CL placement inside the ocular environment. In the last years, many studies have been finalized to the friction measurements of CLs surface, finding conflicting data due to a lack in standardized protocol. The aim of this review is primarily to show evident relationships between CLs surface properties (i.e. wettability, tear evaporation, tear film quality, etc.) and the coefficient of friction (CoF), resulting therefore the most relevant physical quantity in the CLs characterization. In addition, we reported the most recent studies in CLs tribology, which highlight that the introduction of a standard protocol in CoF measurements is necessary to obtain reproducible results, considering the aim to evaluate in a more precise way the relationship between this material surface property and comfort in CLs users.

Abstract
PURPOSE Sexual dysfunctions are often experienced by male patients with acromegaly, due to a combination of hypogonadism and other comorbidities, but are a scarcely investigated complication. Erectile dysfunction is also closely related to cardiovascular diseases through endothelial dysfunction. Therefore, this project aimed to assess the prevalence of erectile dysfunction in a population of acromegalic men and evaluate its association with cardio-metabolic disorders, also exploring associations with androgen and estrogen receptor gene polymorphisms. METHODS Sexually active men aged 18-65 with previous diagnosis of acromegaly were recruited. Clinical and laboratory data were retrospectively collected. Each patient also provided a blood sample for AR and ERβ gene polymorphisms analyses and filled out the IIEF-15 questionnaire. RESULTS Twenty men with previous diagnosis of acromegaly (mean age 48.4 ± 10.0 years) were recruited. 13/20 subjects (65%) had erectile dysfunction, but only four had a concurrent biochemical hypogonadism, with no significant correlation with IIEF-15 scores. Total testosterone negatively correlated with sexual intercourse satisfaction domain (ρ = - 0.595; p = 0.019) and general satisfaction domain (ρ = - 0.651; p = 0.009). IGF-1 levels negatively correlated with biochemical hypogonadism (ρ = - 0.585; p = 0.028). The number of CAG and CA repeats in AR and ERβ receptors genes was not significantly associated with IIEF-15 scores or with GH/IGF-1 levels, but a negative correlation between CA repeats and the presence of cardiomyopathy (ρ = - 0.846; p = 0.002) was present. CONCLUSIONS Men with acromegaly have a high prevalence of erectile dysfunction, but it does not appear to be correlated with treatments, testosterone levels and AR/ER-beta signaling. Nonetheless, a shorter CA polymorphic trait (ERbeta) is associated with the presence of cardiomyopathy. If confirmed, these data may suggest an association between an incorrect hormonal balance and increased cardiovascular risk in acromegaly subjects.

Abstract
INTRODUCTION The French day hospital program specialized in eating disorders (ED) opened in January 2018. Our study presents preliminary data on clinical profiles of patients with anorexia nervosa (AN). We describe more specifically clinical characteristics of patients with early onset AN and according to their therapeutics orientations. Then, we compare the weight gain of patients managed only in day-patient (DP) treatment with those managed initially inpatient (IP) treatment and relays in DP. METHODS Ninety-two patients with AN, aged between 8 and 18 years, were evaluated with several questionnaires (EDI-2, EDE-Q, BSQ, EDS-R, CDI, STAI-Y, VSP-A, EPN-13). RESULTS Patients with early onset AN, n = 23 (25.3%), presented more restrictive behaviors, less marked dietary symptomatology, a lower degree of clinical perfectionism and a less marked feeling of ineffectiveness than adolescent patients with AN. Regarding the choice of hospitalization modality (DP alone or IP-DP), the only difference highlighted was the severity of patient undernutrition. Among the patients who were treated (IP-DP n = 27 vs DP alone n = 25), the weight evolution after one month and at discharge was favorable for both groups. CONCLUSION These preliminary data suggest the effectiveness of DP in the care of AN in children and adolescents.

Abstract
For brain protection, the blood-brain barrier and blood-cerebrospinal fluid barrier limit the traffic of molecules between blood and brain tissue and between blood and cerebrospinal fluid, respectively. Besides their protective function, brain barriers also limit the passage of therapeutic drugs to the brain, which constitutes a great challenge for the development of therapeutic strategies for brain disorders. This problem has led to the emergence of novel strategies to treat neurological disorders, like the development of nanoformulations to deliver therapeutic agents to the brain. Recently, functional molecular clocks have been identified in the blood-brain barrier and in the blood-cerebrospinal fluid barrier. In fact, circadian rhythms in physiological functions related to drug disposition were also described in brain barriers. This opens the possibility for chronobiological approaches that aim to use time to improve drug efficacy and safety. The conjugation of nanoformulations with chronobiology for neurological disorders is still unexplored. Facing this, here, we reviewed the circadian rhythms in brain barriers, the nanoformulations studied to deliver drugs to the brain, and the nanoformulations with the potential to be conjugated with a chronobiological approach to therapeutic strategies for the brain.

Abstract
The circadian clock controls behavior and physiology. Presently, there is clear evidence of a connection between this timing system and cancer development/progression. Moreover, circadian rhythm consideration in the therapeutic action of anticancer drugs can enhance the effectiveness of cancer therapy. Nanosized drug delivery systems (DDS) have been demonstrated to be suitable engineered platforms for drug targeted/sustained release. The investigation of the chronobiology-nanotechnology relationship, i.e., timing DDS performance according to a patient's circadian rhythm, may greatly improve cancer clinical outcomes. In the present work, we synthesized nanosystems based on an octa-arginine (R8)-modified poly(amidoamine) dendrimer conjugated with the anticancer drug paclitaxel (PTX), G4-PTX-R8, and its physicochemical properties were revealed to be appropriate for in vitro delivery. The influence of the circadian rhythm on its cellular internalization efficiency and potential therapeutic effect on human cervical cancer cells (HeLa) was studied. Cell-internalized PTX and caspase activity, as a measure of induced apoptosis, were monitored for six time points. Higher levels of PTX and caspase-3/9 were detected at T8, suggesting that the internalization of G4-PTX-R8 into HeLa cells and apoptosis are time-specific/-regulated phenomena. For a deeper understanding, the clock protein Bmal1-the main regulator of rhythmic activity, was silenced by Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology. Bmal1 silencing was revealed to have an impact on both PTX release and caspase activity, evidencing a potential role for circadian rhythm on drug delivery/therapeutic effect mediated by G4-PTX-R8.

Abstract
Molecular clocks are responsible for defining 24-h cycles of behaviour and physiology that are called circadian rhythms. Several structures and tissues are responsible for generating these circadian rhythms and are named circadian clocks. The suprachiasmatic nucleus of the hypothalamus is believed to be the master circadian clock receiving light input via the optic nerve and aligning internal rhythms with environmental cues. Studies using both in vivo and in vitro methodologies have reported the relationship between the molecular clock and sex hormones. The circadian system is directly responsible for controlling the synthesis of sex hormones and this synthesis varies according to the time of day and phase of the estrous cycle. Sex hormones also directly interact with the circadian system to regulate circadian gene expression, adjust biological processes, and even adjust their own synthesis. Several diseases have been linked with alterations in either the sex hormone background or the molecular clock. So, in this chapter we aim to summarize the current understanding of the relationship between the circadian system and sex hormones and their combined role in the onset of several related diseases.

Abstract
The clinical involvement and antifungal susceptibility of Aspergillus section Circumdati are poorly known. We analyzed 52 isolates, including 48 clinical isolates, belonging to 9 species inside the section Circumdati. The whole section exhibited, by the EUCAST reference method, a poor susceptibility to amphotericin B, but species/series-specific patterns were observed for azole drugs. This underlines the interest in getting an accurate identification inside the section Circumdati to guide the choice of antifungal treatment in clinical practice.

Abstract
Quercetin is a natural flavonoid with high anticancer activity, especially for related-HPV cancers such as cervical cancer. However, quercetin exhibits a reduced aqueous solubility and stability, resulting in a low bioavailability that limits its therapeutic use. In this study, chitosan/sulfonyl-ether-β-cyclodextrin (SBE-β-CD)-conjugated delivery systems have been explored in order to increase quercetin loading capacity, carriage, solubility and consequently bioavailability in cervical cancer cells. SBE-β-CD/quercetin inclusion complexes were tested as well as chitosan/SBE-β-CD/quercetin-conjugated delivery systems, using two types of chitosan differing in molecular weight. Regarding characterization studies, HMW chitosan/SBE-β-CD/quercetin formulations have demonstrated the best results, which are obtaining nanoparticle sizes of 272.07 ± 2.87 nm, a polydispersity index (PdI) of 0.287 ± 0.011, a zeta potential of +38.0 ± 1.34 mV and an encapsulation efficiency of approximately 99.9%. In vitro release studies were also performed for 5 kDa chitosan formulations, indicating a quercetin release of 9.6% and 57.53% at pH 7.4 and 5.8, respectively. IC50 values on HeLa cells indicated an increased cytotoxic effect with HMW chitosan/SBE-β-CD/quercetin delivery systems (43.55 μM), suggesting a remarkable improvement of quercetin bioavailability.

Abstract
Abstract
Background
Many studies on contextual health effects suffer from compositional bias and selective migration into neighbourhoods. Longitudinal natural experiments have the potential to overcome these limitations, and there are several opportunities for this research design in the migration context. We aimed to synthesize evidence from natural experiments among migrants studying the effect of contextual factors on health and healthcare.
Methods
Peer-reviewed literature in English or German was systematically searched in four major databases in December 2021. Following systematic abstract- and fulltext-screening, 32 studies were included for analysis. Evidence on contextual impacts on physical and mental health, mortality, and healthcare was narratively synthesized and quality appraisal conducted.
Results
We found four types of contextual health effects: factors of the place of residence in receiving countries (n = 6), migration-context interactions (n = 10), policy environments (n = 15) and cultural factors (n = 1). Results show the negative impacts of post-migratory contexts on physical health and mortality and the favourable impacts on child health. Impacts on mental health are mixed. Analyses of policy contexts indicate the negative impacts of restrictive migration and social policies on healthcare utilization, mental health and mortality as well as the positive effects when restrictions are lifted.
Conclusions
Natural experiments can serve as powerful tools in disentangling the effect of context on health and reducing bias through self-selection. Results demonstrate the negative impacts for health which lie at the nexus of migration and neighbourhood disadvantage. At the same time, studies uncover the potential of health, welfare and visa programs to counteract such disadvantages and create healthy post-migratory contexts. With careful consideration of causal pathways, results from migration contexts can serve as a magnifying glass for effects of context in other population groups.
Key messages
• Natural experiments can serve as powerful tools in disentangling the effect of context on health and reduce bias through self-selection.
• Results show the negative impacts for health that lie at the nexus of migration and neighborhood disadvantage, as well as the potential of inclusionary policies to counteract them.

Abstract
Abstract
Issue/Problem
COVID-19 pandemic has amplified the amount of health information available; however, hard-to-reach populations remain and much of the information available is not accurate. Therefore, the use of new proximity approaches in the promotion of health literacy is essential because people face challenges and barriers when trying to find information relevant to them.
Description of the problem
From the beginning of the COVID-19 pandemic in 2020, the Division of Literacy, Health and Wellbeing of the Directorate-General of Health in Portugal developed Social Mobilization and Community Engagement training sessions-which included a presentation and a toolkit of flyers/posters/videos. These sessions had the goal of disseminating public health measures through good practices in health literacy and communication methods/skills to promote efficient communication among people who play an active role (as microinfluencers) in prevention and mitigation of risks associated with COVID-19, as is the case of pharmacists.
Results
A total of 200 Portuguese pharmacists enrolled on the Social mobilization training session in November 2021. More than 150 initiatives were implemented thereafter by those microinfluencers (pharmacists) in the local communities-31% directed to children or young people, 31% to older adults, and 13.8% to migrants or tourists. 70% of the participants considered the materials of the toolkit as adequate and sufficient, and 62.1% answered that people in the community showed interest for those materials available in the pharmacies.
Lessons
This Social mobilization project was important because it assembled and preserved trust- basing the information of the training on reliable sources about COVID-19 virus. It also trained the microinfluencers (pharmacists) in communication strategies. All these approaches were important to prevent and mitigate the impact of COVID-19 via adoption of non-pharmacological measures and promotion of vaccination.
Key messages
• Portugal was pioneer in promoting Social mobilization and community engagement training sessions, maintaining a proximity communication, tailoring the information, and maximizing its impact.
• Within the group of health professionals, pharmacists are a privileged group to promote these communication strategies and social mobilization due to their proximity with the local community.

Abstract
Abstract
Introduction
Socioeconomic conditions affect the dynamics of the COVID-19 pandemic. We analysed the association between area-level socioeconomic deprivation, proportion of non-nationals, and Covid-19 incidence in Germany.
Methods
Using nationally representative data at the level of 401 German districts from three waves of infection (January-2020 to May-2021), we fitted Bayesian spatiotemporal models to assess the association between socioeconomic deprivation, proportion of non-nationals, and Covid-19 incidence, controlling for age, sex, vaccination coverage, settlement structure, spatial and temporal effects. We estimated risk ratios (RR) and corresponding 95% credible intervals (95%-CrI) for deprivation quintiles. We further examined the deprivation domains (education, income, occupation), interactions between deprivation, sex and the proportion of non-nationals, and explored potential pathways from deprivation to Covid-19 incidence.
Results
Covid-19 incidence risk was 15% higher (RR = 1.15, 95%-CrI=1.06-1.24) in areas with the highest deprivation quintile (Q5) compared to the least deprived areas (Q1). Medium-low (Q2), medium (Q3), and medium-high (Q4) deprived districts showed 5% (1.05, 0.98-1.13), 8% (1.08, 1.01-1.15), and 6% (1.00, 1.00-1.12) higher risk, respectively, compared to the least deprived. Districts with higher proportion of non-nationals showed higher risk compared to districts with lowest proportion, but the association weakened across the three waves. During the first wave, an inverse association was observed with highest risk in least deprived areas (Q1). Deprivation interacted with sex, but not credibly with the proportion of non-nationals.
Conclusions
Socioeconomic deprivation and proportion of non-nationals are independently associated with Covid-19 incidence. Regional planning of non-pharmaceutical interventions and vaccination strategies would benefit from consideration of area-level deprivation and non-national residency.

Abstract
Abstract
Background
Despite improvements in cancer management, cancer treatment related cardiac dysfunction (CTRCD) is a growing medical problem that impact cancer patients' prognosis, especially when it leads to early interruptions of effective anticancer therapies. Heart failure (HF) therapies are recommended in patients who develop symptomatic CTRCD or asymptomatic decrease in left ventricular ejection fraction (LVEF). However, the beneficial effect of sodium-glucose co-transporter 2 (SGLT2) inhibitors was not prospectively tested in patients with cancer and CTRCD
Purpose
EMPACARD-treatment is a prospective registry aiming at evaluating the usefulness of empagliflozin on left ventricular remodelling in patients with metastatic breast cancer and refractory CTRCD.
Methods
Metastatic breast cancer patients, who develop refractory CTRCD during or after anthracycline chemotherapy and/or HER2 targeted therapies were prospectively included in our study and treated with empagliflozin 10mg/day on top of their current HF therapies. Refractory CTRCD was defined as symptomatic HF in patients treated with optimal doses of neurohormonal HF therapies, including sacubitril/valsartan. Clinical and echocardiographic variables were analysed to determine the potential benefits of empagliflozin on left ventricular remodelling (LVEF and left ventricular diastolic diameter (LVDD)), NT-proBNP levels, NHYA class and 6 minutes walking test (6MWT). The median follow-up was 6 months.
Continuous variables were summarized as medians with interquartile ranges (IQR) and compared with Wilcoxon's test for paired samples. Categorical values were expressed as percentages and compared with the chi-squared test. Statistical significance was considered with a p-value of less than 0.05. All analyses were performed with R version 4.1.1.
Results
19 metastatic breast cancer patients were included. Baseline characteristics and HF treatments are described in table 1. One patient received a heart transplant, and there were no deaths. At 6 months follow up LVEF significantly improved from 30% (IQR 27.5–32) to 38% (IQR (33.5–39), (p<0.001), NT-proBNP decreased from 1342 pg/ml (IQR (977–1756) to 784 pg/ml (IQR 641–1099.5) (p<0.0001), and similar improvements were observed in LVDD and 6MWT (Table 2). NYHA functional class improved in 95% of patients from class III to I or II at 6 months follow-up (p<0.003).
Conclusions
Guideline-based HF therapy, including empagliflozin improves LV remodelling in patients with cancer and refractory CTRCD. Empagliflozin might be a promising treatment option in patients with refractory CTRCD

Abstract
The circadian system is responsible for internal functions and regulation of the organism according to environmental cues (zeitgebers). Circadian rhythm dysregulation or chronodisruption has been associated with several diseases, from mental to autoimmune diseases, and with life quality change. Following this, some therapies have been developed to correct circadian misalignments, such as light therapy and chronobiotics. In this manuscript, we describe the circadian-related diseases so far investigated, and studies reporting relevant data on this topic, evidencing this relationship, are included. Despite the actual limitations in published work, there is clear evidence of the correlation between circadian rhythm dysregulation and disease origin/development, and, in this way, clock-related therapies emerge as great progress in the clinical field. Future improvements in such interventions can lead to the development of successful chronotherapy strategies, deeply contributing to enhanced therapeutic outcomes.

Abstract
Mastocytosis is characterized by clonal expansion of mast cells, with abnormal accumulation in different organs. Perioperatively, numerous stimuli may lead to the release of vasoactive substances by mast cells. Parturients with systemic mastocytosis pose a challenge to the anesthesiologist: on one hand, the pain and stress of labor may lead to greater mast cell activation and, on the other, the administration of drugs that may possibly trigger the release of mast cell mediators. The authors describe a case of a 34-year-old pregnant woman with systemic mastocytosis who requests labor analgesia. An epidural analgesia was performed after induction of labor, after considering anesthetic particularities. The epidural procedure, labor and delivery were uneventful. A review of systemic mastocytosis is provided and its anesthetic considerations are discussed.

Abstract
Error-related electroencephalographic (EEG) signals have been widely studied concerning the human cognitive capability of differentiating between erroneous and correct actions. Midfrontal error-related negativity (ERN) and theta band oscillations are believed to underlie post-action error monitoring. However, it remains elusive how early monitoring activity is trackable and what are the pre-response brain mechanisms related to performance monitoring. Moreover, it is still unclear how task-specific parameters, such as cognitive demand or motor control, influence these processes. Here, we aimed to test pre- and post-error EEG patterns for different types of motor responses and investigate the neuronal mechanisms leading to erroneous actions. We implemented a go/no-go paradigm based on keypresses and saccades. Participants received an initial instruction about the direction of response to be given based on a facial cue and a subsequent one about the type of action to be performed based on an object cue. The paradigm was tested in 20 healthy volunteers combining EEG and eye tracking. We found significant differences in reaction time, number, and type of errors between the two actions. Saccadic responses reflected a higher number of premature responses and errors compared to the keypress ones. Nevertheless, both led to similar EEG patterns, supporting previous evidence for increased ERN amplitude and midfrontal theta power during error commission. Moreover, we found pre-error decreased theta activity independent of the type of action. Source analysis suggested different origin for such pre- and post-error neuronal patterns, matching the anterior insular cortex and the anterior cingulate cortex, respectively. This opposite pattern supports previous evidence of midfrontal theta not only as a neuronal marker of error commission but also as a predictor of action performance. Midfrontal theta, mostly associated with alert mechanisms triggering behavioral adjustments, also seems to reflect pre-response attentional mechanisms independently of the action to be performed. Our findings also add to the discussion regarding how salience network nodes interact during performance monitoring by suggesting that pre- and post-error patterns have different neuronal sources within this network.

Abstract
Cancer is the second leading cause of death worldwide. Cervical cancer, for instance, is considered a major scourge in low-income countries. Its development is mostly associated with the human papillomavirus persistent infection and despite the availability of preventive vaccines, they are only widely administered in more developed countries, thus leaving a large percentage of unvaccinated women highly susceptible to this type of cancer. Current treatments are based on invasive techniques, being far from effective. Therefore, the search for novel, advanced and personalized therapeutic approaches is imperative. Flavonoids belong to a group of natural polyphenolic compounds, well recognized for their great anticancer capacity, thus promising to be incorporated in cancer therapy protocols. However, their use is limited due to their low solubility, stability and bioavailability. To surpass these limitations, the encapsulation of flavonoids into delivery systems emerged as a valuable strategy to improve their stability and bioavailability. In this context, the aim of this review is to present the most reliable flavonoids-based delivery systems developed for anticancer therapies and the progress accomplished, with a special focus on cervical cancer therapy. The gathered information revealed the high therapeutic potential of flavonoids and highlights the relevance of delivery systems application, allowing a better understanding for future studies on effective cancer therapy.

Abstract
Nucleic acid vaccines have been proven to be a revolutionary technology to induce an efficient, safe and rapid response against pandemics, like the coronavirus disease (COVID-19). Minicircle DNA (mcDNA) is an innovative vector more stable than messenger RNA and more efficient in cell transfection and transgene expression than conventional plasmid DNA. This work describes the construction of a parental plasmid (PP) vector encoding the receptor-binding domain (RBD) of the S protein from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the use of the Design of Experiments (DoE) to optimize PP recombination into mcDNA vector in an orbital shaker. First, the results revealed that host cells should be grown at 42 °C and the Terrific Broth (TB) medium should be replaced by Luria Broth (LB) medium containing 0.01% L-arabinose for the induction step. The antibiotic concentration, the induction time, and the induction temperature were used as DoE inputs to maximize the % of recombined mcDNA. The quadratic model was statistically significant (p-value < 0.05) and presented a non-significant lack of fit (p-value > 0.05) with a suitable coefficient of determination. The optimal point was validated using 1 h of induction, at 30 °C, without the presence of antibiotics, obtaining 93.87% of recombined mcDNA. Based on these conditions, the production of mcDNA was then maximized in a mini-bioreactor platform. The most favorable condition obtained in the bioreactor was obtained by applying 60% pO2 in the fermentation step during 5 h and 30% pO2 in the induction step, with 0.01% L-arabinose throughout 5 h. The yield of mcDNA-RBD was increased to a concentration of 1.15 g/L, when compared to the orbital shaker studies (16.48 mg/L). These data revealed that the bioreactor application strongly incremented the host biomass yield and simultaneously improved the recombination levels of PP into mcDNA. Altogether, these results contributed to improving mcDNA-RBD biosynthesis to make the scale-up of mcDNA manufacture simpler, cost-effective, and attractive for the biotechnology industry.

Abstract
Error monitoring is the metacognitive process by which we are able to detect and signal our errors once a response has been made. Monitoring when the outcome of our actions deviates from the intended goal is crucial for behavior, learning, and the development of higher-order social skills. Here, we explored the neuronal substrates of error monitoring during the integration of facial expression cues using electroencephalography (EEG). Our goal was to investigate the signatures of error monitoring before and after a response execution dependent on the integration of facial cues. We followed the hypothesis of midfrontal theta as a robust neuronal marker of error monitoring since it has been consistently described as a mechanism to signal the need for cognitive control. Also, we hypothesized that EEG frequency-domain components might bring advantage to study error monitoring in complex scenarios as it carries information from locked and non-phase-locked signals. A challenging go/no-go saccadic paradigm was applied to elicit errors: integration of facial emotional signals and gaze direction was required to solve it. EEG data were acquired from twenty healthy participants and analyzed at the level of theta band activity during response preparation and execution. Although theta modulation has been consistently demonstrated during error monitoring, it is still unclear how early it starts to occur. We found theta power differences at midfrontal channels between correct and error trials. Theta was higher immediately after erroneous responses. Moreover, before response initiation we observed the opposite: lower theta preceding errors. These results suggest theta band activity not only as an index of error monitoring, which is needed to enhance cognitive control, but also as a requisite for success. This study adds to previous evidence for the role of theta band in error monitoring processes by revealing error-related patterns even before response execution in complex tasks, and using a paradigm requiring the integration of facial expression cues.

Abstract
The conception of novel anticancer delivery systems and the combination of chronobiology with nanotechnology may provide a powerful tool to optimize cancer therapy. In this work, polyethylenimine (PEI) has been used to complex p53 encoded plasmid DNA (pDNA), and the anticancer drug methotrexate (MTX) has also been loaded into the vectors. To investigate the influence of circadian clock on drug/gene delivery efficiency, HeLa, C33A and fibroblast cells have been transfected with developed PEI/pDNA/MTX delivery vectors at six different time points. Phenomena as the cellular uptake/internalization, drug/gene delivery and p53 protein production have been evaluated. The cell-associated MTX fluorescence have been monitored, and p53 protein levels quantified. In HeLa and C33A cancer cells, significant levels of MTX were found for T8 and T12. For these time points, a high amount of p53 protein was quantified. Confocal microscopy images showed successful HeLa cell’s uptake of PEI/pDNA/MTX particles, at T8. In comparison, poor levels of MTX and p53 protein were found in fibroblasts; nevertheless, results indicated rhythmicity. Data demonstrate the influence of circadian rhythm on both cancer-cells targeting ability and transfection performance of PEI/pDNA/MTX carriers and seemed to provide the optimum time for drug/gene delivery. This report adds a great contribution to the field of cancer chronobiology, highlighting the relationship between circadian rhythm and nanodelivery systems, and charting the path for further research on a, yet, poorly explored but promising topic.

Abstract
IMPORTANCE Pharmacists are among the healthcare professionals involved in the response to the COVID-19 pandemic, maintaining essential services. In the context of restrictions and reorganization of human resources, as a result of policies recently applied to the health sector, following international guidelines, and given the scarcity of data on burnout in pharmaceutical activity, it was considered highly relevant to promote a nationwide survey aiming to collect more complete evidence on the burnout syndrome and to understand how pharmacists have viewed their work and the people they worked closely with. OBJECTIVES The study aimed to assess the occurrence of pharmacist burnout and determine outcomes for each of its dimensions; identify potentially associated characteristics; and determine profiles and critical limits. DESIGN A cross-sectional observational study conducted by a multidisciplinary panel from the Portuguese Pharmaceutical Society (PPS). Professionals from community and hospital pharmacies who were at the forefront of the COVID-19 response were involved in (i) confirming the need and pertinence for conducting this research, (ii) identifying the main factors leading to pharmaceutical emotional distress ("burnout"), and (iii) disseminating the survey. The questionnaire was designed for digital voluntary, confidential, and anonymous participation and divided into four segments of data collection: (i) demographics, (ii) employment and workplace characterization, (iii) pandemic impact on labor activity, and (iv) burnout assessment (as described ahead). SETTING An electronic survey was addressed to all PPS members, and an account was created solely to manage the questionnaire data for the research team. The web-based and user-friendly platform Google Forms supported the data capture and provided an intuitive interface for validated data entry. PARTICIPANTS In a population of 15,565 pharmacists (members of the PPS), the minimum recommended sample size (Epi Info software), with a 5% margin of error and a 99.9% confidence interval, should be 1,012 individuals. A total of 1,362 pharmacists participated in the study. Of these, 91.4% (n = 1,246) were involved in direct patient care activity and 7.7% (n = 106) in non-direct patient care activity.

Abstract
Glioblastoma multiforme (GBM) is a very aggressive and heterogeneous glioma. Currently, GBM is treated with a combination of surgery, radiotherapy, chemotherapy (e.g. temozolamide) and Tumour Treating Fields. Unfortunately, the mean survival is still around 15 months. This poor prognosis is associated with therapy resistance, tumor recurrence, and limited delivery of drugs due to the blood-brain barrier nature. Nanomedicine, the application of nanotechnology to medicine, has revolutionized many health fields, specifically cancer diagnosis and treatment. This review explores the particularities of different nanosystems (i.e., superparamagnetic, polymeric and gold nanoparticles, and liposomes) as well as how they can be applied to the treatment and diagnosis of GBM. As described, the most of the cited examples are on the preclinical phase; however, positive results were obtained and thus, the distance to achieve an effective treatment is shorter every day.

Abstract
INTRODUCTION The Centro de Estudos do Bebé e da Criança in Hospital Dona Estefânia has organized a multidisciplinary model for children under three with suspected autism spectrum disorder, thus implementing the recent guidelines established by the Directorate General for Health. The aim of this study is to describe this model and case series. MATERIAL AND METHODS A retrospective descriptive study of observed children with suspected ASD. They were observed according to the model of the Centro de Estudos do Bebé e da Criança and DC:0-5TM classification, between January 2018 and September 2019. RESULTS The study included 178 children. The average age at the initial assessment was 27 months. From the total sample, 116 children concluded the diagnostic sessions (axis I): Autism Spectrum Disorder/Early Atypical (36%), Developmental Language Disorder (18%), Other (19%). Factors of axes II, III, IV and V of DC:0-5TM were determinant for clinical diagnosis in 26%. DISCUSSION Of 116 children, 36% were diagnosed with Autism Spectrum Disorder. This highlights the diagnostic challenge posed by neurodevelopmental disorders in early infancy. The sample shows that the characteristics of the relationship with the caregiver (axis II), presence of physical conditions (axis III), psycho-social stressors (axis IV) and developmental trajectory (axis V) have a significant clinical impact. In the future, the initial assessment should take place well before the age of 27 months because of the impact on prognosis. CONCLUSION This model is a pioneering approach in Portugal. It promotes a common approach of Child and Adolescent Psychiatry and Neuropediatrics/Developmental Pediatrics in early infancy. Moreover, it increases the diagnostic acuity of Autism Spectrum Disorders and early therapeutic intervention.

Abstract
In current times, DNA vaccines are seen as a promising approach to treat and prevent diseases, such as virus infections and cancer. Aiming at the production of a functional and effective plasmid DNA (pDNA) delivery system, four chitosan polymers, differing in the molecular weight, were studied using the design of experiments (DoE) tool. These gene delivery systems were formulated by ionotropic gelation and exploring the chitosan and TPP concentrations as DoE inputs to maximize the nanoparticle positive charge and minimize their size and polydispersity index (PDI) as DoE outputs. The obtained linear and quadratic models were statistically significant (p-value < 0.05) and non-significant lack of fit, with suitable coefficient of determination and the respective optimal points successfully validated. Furthermore, morphology, stability and cytotoxicity assays were performed to evaluate the endurance of these systems over time and their further potential for future in vitro studies. The subsequent optimization process was successful achieved for the delivery systems based on the four chitosan polymers, in which the smallest particle size was obtained for the carrier containing the 5 kDa chitosan (~82 nm), while the nanosystem prepared with the high molecular weight (HMW) chitosan displayed the highest zeta potential (~+26.8 mV). Delivery systems were stable in the formulation buffer after a month and did not exhibit toxicity for the cells. In this sense, DoE revealed to be a powerful tool to explore and tailor the characteristics of chitosan/pDNA nanosystems significantly contributing to unraveling an optimum carrier for advancing the DNA vaccines delivery field.

Abstract
DNA vaccines have emerged as innovative approaches that have great potential to overcome the limitations of current conventional vaccines. Plasmid DNA vaccines are often safer than other vaccines because they carry only antigen genetic information, are more stable and easier to produce, and can stimulate both humoral and cellular immune responses. Although the results of ongoing clinical trials are very promising, some limitations compromise the immunogenicity of these vaccines. Thus, this review describes different strategies that can be explored to improve the immunogenicity of plasmid DNA vaccines, including the optimization of the plasmid vector backbone, the use of different methods for vaccine delivery, the use of alternative administration routes and the inclusion of adjuvants. In combination, these improvements could lead to the successful clinical use of plasmid DNA vaccines.

Abstract
Mastocytosis is characterized by clonal expansion of mast cells, with abnormal accumulation in different organs. Perioperatively, numerous stimuli may lead to the release of vasoactive substances by mast cells. Parturients with systemic mastocytosis pose a challenge to the anesthesiologist: on one hand, the pain and stress of labor may lead to greater mast cell activation and, on the other, the administration of drugs that may possibly trigger the release of mast cell mediators. The authors describe a case of a 34-year-old pregnant woman with systemic mastocytosis who requests labor analgesia. An epidural analgesia was performed after induction of labor, after considering anesthetic particularities. The epidural procedure, labor and delivery were uneventful. A review of systemic mastocytosis is provided and its anesthetic considerations are discussed.

Abstract
BACKGROUND/AIM Canine Cutaneous Histiocytoma (CCH) is a Langerhans' cells benign tumour that undergoes spontaneous regression. The aim of the present study was to investigate the role of angiogenesis, a key step for tumour development, in CCH regression. MATERIALS AND METHODS 50 CCH samples were classified into 4 histological groups according to a regression scale, and evaluated for expression of vascular endothelial factor-A (VEGF-A) and its receptor VEGFR-2 as well as microvessel density (MVD). RESULTS Tumours during early stages of the regressive process had a lower MVD compared to later stages, while CCH tumoural cells showed a limited production of VEGF, but higher levels of VEGFR-2. On the contrary, tumours in advanced phases of regression showed a higher number of neovessels, probably associated with the inflammatory state and the healing process. CONCLUSION Our results suggest that angiogenesis may be compromised at early stages of histiocytoma development and this may be a determinant of regression in this tumour.

Abstract
A mitochondrion is a cellular organelle able to produce cellular energy in the form of adenosine triphosphate (ATP). As in the nucleus, mitochondria contain their own genome: the mitochondrial DNA (mtDNA). This genome is particularly susceptible to mutations that are at the basis of a multitude of disorders, especially those affecting the heart, the central nervous system and muscles. Conventional clinical practice applied to mitochondrial diseases is very limited and ineffective; a clear need for innovative therapies is demonstrated. Gene therapy seems to be a promising approach. The use of mitochondrial DNA as a therapeutic, optimized by peptide-based complexes with mitochondrial targeting, can be seen as a powerful tool in the reestablishment of normal mitochondrial function. In line with this requirement, in this work and for the first time, a mitochondrial-targeting sequence (MTS) has been incorporated into previously researched peptides, to confer on them a targeting ability. These peptides were then considered to complex a plasmid DNA (pDNA) which contains the mitochondrial gene ND1 (mitochondrially encoded NADH dehydrogenase 1 protein), aiming at the formation of peptide-based nanoparticles. Currently, the ND1 plasmid is one of the most advanced bioengineered vectors for conducting research on mitochondrial gene expression. The formed complexes were characterized in terms of pDNA complexation capacity, morphology, size, surface charge and cytotoxic profile. These data revealed that the developed carriers possess suitable properties for pDNA delivery. Furthermore, in vitro studies illustrated the mitochondrial targeting ability of the novel peptide/pDNA complexes. A comparison between the different complexes revealed the most promising ones that complex pDNA and target mitochondria. This may contribute to the optimization of peptide-based non-viral systems to target mitochondria, instigating progress in mitochondrial gene therapy.

Abstract
DNA vaccines still represent an emergent area of research, giving rise to continuous progress towards several biomedicine demands. The formulation of delivery systems to specifically target mannose receptors, which are overexpressed on antigen presenting cells (APCs), is considered a suitable strategy to improve the DNA vaccine immunogenicity. The present study developed binary and ternary carriers, based on polyethylenimine (PEI), octa-arginine peptide (R8), and mannose ligands, to specifically deliver a minicircle DNA (mcDNA) vaccine to APCs. Systems were prepared at various nitrogen to phosphate group (N/P) ratios and characterized in terms of their morphology, size, surface charge, and complexation capacity. In vitro studies were conducted to assess the biocompatibility, cell internalization ability, and gene expression of formulated carriers. The high charge density and condensing capacity of both PEI and R8 enhance the interaction with the mcDNA, leading to the formation of smaller particles. The addition of PEI polymer to the R8-mannose/mcDNA binary system reduces the size and increases the zeta potential and system stability. Confocal microscopy studies confirmed intracellular localization of targeting systems, resulting in sustained mcDNA uptake. Furthermore, the efficiency of in vitro transfection can be influenced by the presence of R8-mannose, with great implications for gene expression. R8-mannose/PEI/mcDNA ternary systems can be considered valuable tools to instigate further research, aiming for advances in the DNA vaccine field.

Abstract
New biotechnological strategies are being explored, aimed at rapid and economic manufacture of large quantities of DNA vaccines with the required purity for therapeutic applications, as well as their correct delivery as biopharmaceuticals to target cells. This report describes the purification of supercoiled (sc) HPV-16 E6/E7 plasmid DNA (pDNA) vaccine from a bacterial lysate, using an arginine-based monolith, presenting a spacer arm in its configuration. To enhance the performance of the purification process, monolith modification with the spacer arm can improve accessibility of the arginine ligand. By using a low NaCl concentration at pH 7.0, a condition to eliminate the RNA impurity directly in the flow through was established. The pH increase to 7.5 allowed the elimination of non-functional pDNA isoforms, the sc pDNA being recovered by increasing the ionic strength. As well as a binding capacity of 2.53 mg/mL obtained with a pre-purified sc pDNA sample, the column also purified sc pDNA from high lysate loading, with capacities above 1 mg/mL. Due to the sample displacement phenomena, non-functional pDNA isoforms were eliminated throughout column loading, favoring the degree of purity of final sc pDNA of 93.3%-98.5%. Thereafter, purified sc pDNA was successfully encapsulated into CaCO3-gelatin nano-complexes. Delivery of the pDNA-carriers to THP-1 cells was assessed through pDNA cellular uptake evaluation and correct E6 expression was verified by mRNA and protein detection. A biotechnological platform was established for sc pDNA purification and delivery to dendritic cells, stimulating further in vivo studies.

Abstract
Abstract
Introduction
Sick euthyroid syndrome (SES) constitutes an acute response to stress, and patients who develop it usually show more severe illness than those who do not. It could be related to disease severity in acute coronary syndrome (ACS), as assessed with Killip-Kimball class (KK), since cardiomyocytes are specifically sensitive to T3 levels.
Objective
To determine the prevalence of SES and low T3 in patients with ACS, and to assess its association with disease severity.
Methods
Prospective, observational and single center study in consecutive patients admitted to the CCU with a diagnosis of ACS. Clinical variables were collected from medical records; blood samples were obtained at admission to measure TSH, T3 and free T4 levels. SES was defined as low T3 with normal TSH and free T4. Maximum KK was determined by treating physicians. Categorical variables were compared with the chi-squared test, and categorical variables with Kruskal-Wallis and Wilcoxon tests. Statistical significance was set at p<0.05.
Results
There were 149 patients with complete data available for analysis. Their age was 67.8±12.4 years, and 64% were male. A total of 16.3% had SES. There were 7.5% patients with SES and KK-A, 34.8% KK-B, 14.3% KK-C and 70% KK-D (p<0.001). Thus, SES was more frequent in patients with some grade of heart failure, particularly cardiogenic shock. Figure 1 shows the difference in T3 values according to Killip-Kimball class.
Conclusion
Cardiomyocytes lack deiodinase and only possess T3 receptors, which makes them dependent on circulating T3 levels. T3 directly stimulates calcium channel and contractile protein synthesis in cardiomyocytes, and its deficit could affect cardiac contractility. Future studies should determine if thyroid hormone administration in cardiogenic shock can improve contractility and contribute to hemodynamic stability.

Abstract
Low dispersal marine intertidal species facing strong divergent selective pressures associated with steep environmental gradients have a great potential to inform us about local adaptation and reproductive isolation. Among these, gastropods of the genus Littorina offer a unique system to study parallel phenotypic divergence resulting from adaptation to different habitats related with wave exposure. In this study, we focused on two Littorina fabalis ecotypes from Northern European shores and compared patterns of habitat-related phenotypic and genetic divergence across three different geographic levels (local, regional and global). Geometric morphometric analyses revealed that individuals from habitats moderately exposed to waves usually present a larger shell size with a wider aperture than those from sheltered habitats. The phenotypic clustering of L. fabalis by habitat across most locations (mainly in terms of shell size) support an important role of ecology in morphological divergence. A genome scan based on amplified fragment length polymorphisms (AFLPs) revealed a heterogeneous pattern of differentiation across the genome between populations from the two different habitats, suggesting ecotype divergence in the presence of gene flow. The contrasting patterns of genetic structure between nonoutlier and outlier loci, and the decreased sharing of outlier loci with geographic distance among locations are compatible with parallel evolution of phenotypic divergence, with an important contribution of gene flow and/or ancestral variation. In the future, model-based inference studies based on sequence data across the entire genome will help unravelling these evolutionary hypotheses, improving our knowledge about adaptation and its influence on diversification within the marine realm.

Abstract
Background A defecation disorder (DD) is a difficulty in evacuation documented by physiological exams. However, this physiological evaluation can be cumbersome, inaccessible and costly. Three “low-cost” tools to evaluate DD—a clinical DD score, the balloon expulsion test (BET) and a digital rectal examination (DRE) score were evaluated as separate or combined tests for DD screening. Methods This prospective study occurred between January 2015 and March 2019 in the Gastroenterology Department of a tertiary hospital. Besides the gold standard physiological tests, constipated patients answered the clinical DD score and were evaluated by DRE and BET [standard and variable volume (VV)]. Results From 98 constipated patients, 35 (38.9%) were diagnosed with DD according to Rome IV criteria, mainly female (n = 30, 86%) with a median age of 60 years old. The clinical DD score revealed an AUC of 0.417 (SE = 0.07, p = 0.191). The DRE score displayed an AUC of 0.56 (SE = 0.063, p = 0.301). The standard BET displayed a sensitivity of 86%, specificity of 58%, positive predictive value (PPV) of 57% and negative predictive value (NPV) of 86%. The sequential VVBET followed by standard BET improved the BET performance regarding the evaluation of DD, with a sensitivity of 86%, specificity of 67%, PPV of 63% and NPV of 87%. The sequential BET had an OR 8.942, p > 0.001, CI 3.18–25.14, revealing to be the most significant predictor for DD screening. Conclusion The sequential BET is a low cost, well-performing DD screening tool, appropriate to the Primary Care Setting.

Abstract
Abstract
Background
The mental health condition and healthcare needs of asylum seeking and refugee (ASR) children are essential aspects of health services organization. We describe the relation between psychosocial functioning, health status and healthcare use of ASR children in Germany using a cross-sectional population-based survey.
Methods
560 ASR adults in 58 collective accommodations in Germany's 3rd largest federal state were randomly sampled and assessed in 2018 (response rate: 42%). 126 participants answered the Strengths and Difficulties Questionnaire (SDQ) to assess children' psychosocial functioning with higher scores suggesting poorer functioning. SDQ dimensions (Emotional; Conduct; Peer; Hyperactivity; ProSocial; Total) were compared by demographics, health (long-lasting illness, physical limitation, pain) and healthcare use (unmet need for a pediatrician/specialist, hospital/emergency department visits). Age and sex-adjusted odds ratios (AOR, 95%CI, Confidence Intervals) for presenting borderline/abnormal scores for each SDQ dimension were computed using logistic regression models depending on children' health and healthcare use.
Results
Valid data of 90 ASR children was analyzed: 57% girls; 40% 10-17 years; 58% from East/West Asia; 56% in Germany for more than a year. A borderline/abnormal SDQ Total score was associated with pain (compared to no pain, AOR, 95%CI=3.14, 1.21-8.10) and with an unmet need for a specialist (4.57, 1.09-19.16). High scores (borderline/abnormal) in the SDQ Emotional dimension were positively associated with a long-lasting illness (5.25, 1.57-17.55), physical limitation (4.28, 2.48-12.27) and pain (3.00, 1.10-8.22), and negatively associated with visiting a pediatrician (0.23, 0.07-0.78), a specialist (0.16, 0.04-0.69) and the emergency department (0.27, 0.08-0.96).
Conclusions
Somatic clinical encounters with ASR children should include the assessment of mental health symptomatology, especially in those with worst physical health conditions.
Key messages
Among asylum seeking and refugee children, a poor physical condition and unmet medical needs are linked with poorer mental health. Provision of care to this vulnerable group must include mental health.

Abstract
Abstract
Background
Changes in the subjective social status (SSS) of migrants, specifically between the pre- and post-migratory movement, can be a relevant determinant of their mental health condition. This study analyzed the effect of downward subjective social mobility to the mental health of asylum seekers and refugees (ASR) in Germany.
Methods
Through a random sampling procedure, 560 adult ASR (18+ years) were recruited across 58 collective accommodation centers in Germanys' 3rd largest state (2018). SSS was assessed with the MacArthur social ladder (10-rungs), in reference to the participants' position in the country of origin and in Germany. Quality of Life (QoL, measured with EUROHIS-QOL), anxiety (General Anxiety Disorder-2) and depressive symptoms (Patient Health Questionnaire-2), were considered as mental health outcomes. Generalized linear regression models were fitted to measure associations between changes in SSS and each outcome.
Results
A loss of 3 or more steps in SSS from origin to Germany (compared to no-change) was significantly associated with poorer scores in QoL (B, standardized coefficient= -2.679, standard error, se = 1.351, p = 0.047), with more symptoms of depression (B = 1.156, se = 0.389, p = 0.003) and anxiety (B = 0.971, se = 0.432, p = 0.025), in models adjusted for SSS in the country of origin. The strength and direction of associations was unaltered after further adjusting for sex, age, educational level and time since arrival, although the coefficient for QoL was non-significant for those declaring a 3-step downward mobility (B= -2.494, se = 1.351, p = 0.066 for QoL; B = 1.048, se = 0.393, p = 0.008 for depression; and B = 1.006, se = 0.438, p = 0.022 for anxiety).
Discussion
The results suggest that interventions should focus on those experiencing social downward mobility and not only prioritize individuals with low social status. Early integration efforts and intersectoral measures to counter social downward mobility could prevent poor mental health among ASR.
Key messages
We analysed the impact to the quality of life and mental health of asylum seekers and refugees, of a change in subjective social status from country of origin to Germany. Asylum seekers and refugees residing in Germany, who perceived a downward social status mobility following their migration process, are at risk for poorer mental health.
