Abstract
Olanzapine is a second-generation antipsychotic that disrupts metabolism and is associated with an increased risk of type 2 diabetes. The hypothalamus is a key region in the control of whole-body metabolic homeostasis. The objective of the current study was to determine how acute peripheral olanzapine administration affects transcription and serine/threonine kinase activity in the hypothalamus. Hypothalamus samples from rats were collected following the pancreatic euglycemic clamp, thereby allowing us to study endpoints under steady state conditions for plasma glucose and insulin. Olanzapine stimulated pathways associated with inflammation, but diminished pathways associated with the capacity to combat endoplasmic reticulum stress and G protein-coupled receptor activity. These pathways represent potential targets to reduce the incidence of type 2 diabetes in patients taking antipsychotics.

Abstract
BACKGROUND Plant-based extracts have been recently used as sustainable tools to improve biotic and abiotic stress tolerance and increase grape (Vitis vinifera L.) quality. However, knowledge about the effect of these extracts on secondary metabolism compounds, that are fundamental for grape and wine quality, is still scarce. In this study, a trial was installed in an experimental vineyard with the variety Touriga Franca located at University of Trás-os-Montes e Alto Douro, Baixo Corgo sub-region of the Douro Demarcated Region, Portugal in two growing seasons: 2019 and 2020. The aim was to evaluate the effect of foliar application of nettle (Urtica spp.) extract (NE) and Japanese knotweed (Reynoutria japonica) extract (JKE) on grapevines leaves and berries bioactive compounds contents and antioxidant activity, at veraison and harvest. RESULTS The application of NE increased the total carotenoids in leaves and the total phenolics content and the antioxidant activity (ferric reducing antioxidant power, FRAP) in berries while JKE increased flavonoids content in leaves and the antioxidant activity (2,2-diphenyl-1-picrylhydrazyl, DPPH) in berries. CONCLUSION These extracts seem to have a stimulatory effect on grapevine, enhancing bioactive compounds contents and antioxidant capacity and, consequently, the physiological performance of the plant and the quality of the berries. © 2024 Society of Chemical Industry.

Abstract
Radiotherapy developed empirically through experience balancing tumour control and normal tissue toxicities. Early simple mathematical models formalized this practical knowledge and enabled effective cancer treatment to date. Remarkable advances in technology, computing, and experimental biology now create opportunities to incorporate this knowledge into enhanced computational models. The ESTRO DREAM (Dose Response, Experiment, Analysis, Modelling) workshop brought together experts across disciplines to pursue the vision of personalized radiotherapy for optimal outcomes through advanced modelling. The ultimate vision is leveraging quantitative models dynamically during therapy to ultimately achieve truly adaptive and biologically guided radiotherapy at the population as well as individual patient-based levels. This requires the generation of models that inform response-based adaptations, individually optimized delivery and enable biological monitoring to provide decision support to clinicians. The goal is expanding to models that can drive the realization of personalized therapy for optimal outcomes. This position paper provides their propositions that describe how innovations in biology, physics, mathematics, and data science including AI could inform models and improve predictions. It consolidates the DREAM team's consensus on scientific priorities and organizational requirements. Scientifically, it stresses the need for rigorous, multifaceted model development, comprehensive validation and clinical applicability and significance. Organizationally, it reinforces the prerequisites of interdisciplinary research and collaboration between physicians, medical physicists, radiobiologists, and computational scientists throughout model development. Solely by a shared understanding of clinical needs, biological mechanisms, and computational methods, more informed models can be created. Future research environment and support must facilitate this integrative method of operation across multiple disciplines.

Abstract
This paper presents a bibliometrics analysis aimed at discerning global trends in research on "biomimetics", "biomimicry", "bionics", and "bio-inspired" concepts within civil engineering, using the Scopus database. This database facilitates the assessment of interrelationships and impacts of these concepts within the civil engineering domain. The findings demonstrate a consistent growth in publications related to these areas, indicative of increasing interest and impact within the civil engineering community. Influential authors and institutions have emerged, making significant contributions to the field. The United States, Germany, and the United Kingdom are recognised as leaders in research on these concepts in civil engineering. Notably, emerging countries such as China and India have also made considerable contributions. The integration of design principles inspired by nature into civil engineering holds the potential to drive sustainable and innovative solutions for various engineering challenges. The conducted bibliometrics analysis grants perspective on the current state of scientific research on biomimetics, biomimicry, bionics, and bio-inspired concepts in the civil engineering domain, offering data to predict the evolution of each concept in the coming years. Based on the findings of this research, "biomimetics" replicates biological substances, "biomimicry" directly imitates designs, and "bionics" mimics biological functions, while "bio-inspired" concepts offer innovative ideas beyond direct imitation. Each term incorporates distinct strategies, applications, and historical contexts, shaping innovation across the field of civil engineering.

Abstract
PURPOSE We explored and compared perspectives of reproductive endocrinology and infertility specialists (REIs) and in vitro fertilization (IVF) patients regarding polygenic embryo screening (PES), a new type of preimplantation screening that estimates the genetic chances of developing polygenic conditions and traits in the future. METHODS Qualitative thematic analysis of semi-structured interviews with US-based REIs and IVF patients. RESULTS Clinicians and patients often held favorable views of screening embryos for physical or psychiatric conditions, though clinicians tended to temper their positive attitudes with specific caveats. Clinicians also expressed negative views about screening embryos for traits more frequently than patients, who generally held more positive views. Most clinicians were either unwilling to discuss or offer PES to patients or were willing to do so only under certain circumstances, while many patients expressed interest in PES. Both stakeholder groups envisioned multiple potential benefits or uses of PES and raised multiple potential, interrelated concerns about PES. CONCLUSION A gap exists between clinician and patient attitudes toward PES; clinicians generally maintained reservations about such screening and patients indicated interest in it. Clinicians and patients sometimes imagined using PES to prepare for the birth of a predisposed or "affected" individual-a rationale that is often associated with prenatal testing. Many clinicians and patients held different attitudes depending on what is specifically screened, despite the sometimes blurry distinction between conditions and traits. Considerations raised by clinicians and patients may help guide professional societies in developing guidelines to navigate the uncertain terrain of PES.

Abstract
Metabolic tests are vital to determine in vivo insulin sensitivity and glucose metabolism in preclinical models, usually rodents. Such tests include glucose tolerance tests, insulin tolerance tests, and glucose clamps. Although these tests are not standardized, there are general guidelines for their completion and analysis that are constantly being refined. In this review, we describe metabolic tests in rodents as well as factors to consider when designing and performing these tests.

Abstract
Dopamine (DA) D2-like receptors in both the central nervous system (CNS) and the periphery are key modulators of metabolism. Moreover, disruption of D2-like receptor signaling is implicated in dysglycemia. Yet, the respective metabolic contributions of CNS versus peripheral D2-like receptors including D2 (D2R) and D3 (D3R) receptors remain poorly understood. To address this, we developed new pharmacological tools, D2-like receptor agonists with diminished and delayed blood-brain barrier capability, to selectively manipulate D2R/D3R signaling in the periphery. We designated bromocriptine methiodide (BrMeI), a quaternary methiodide analogue of D2/3R agonist and diabetes drug bromocriptine, as our lead compound based on preservation of D2R/D3R binding and functional efficacy. We then used BrMeI and unmodified bromocriptine to dissect relative contributions of CNS versus peripheral D2R/D3R signaling in treating dysglycemia. Systemic administration of bromocriptine, with unrestricted access to CNS and peripheral targets, significantly improved both insulin sensitivity and glucose tolerance in obese, dysglycemic mice in vivo. In contrast, metabolic improvements were attenuated when access to bromocriptine was restricted either to the CNS through intracerebroventricular administration or delayed access to the CNS via BrMeI. Our findings demonstrate that the coordinated actions of both CNS and peripheral D2-like receptors are required for correcting dysglycemia. Ultimately, the development of a first-generation of drugs designed to selectively target the periphery provides a blueprint for dissecting mechanisms of central versus peripheral DA signaling and paves the way for novel strategies to treat dysglycemia.

Abstract
This study investigates the internal architecture of Asian hornet nests (AHNs) using advanced imaging techniques, such as CT scanning and X-ray radiography, to understand their construction and function. The primary objective and significance of this study centre on drawing inspiration from the creative way Asian hornets construct their nests, with a particular focus on the architecture, design, functionality, and building materials of these nests. The architectural principles governing the construction of these nests, such as the arrangement of hexagonal cells, pedicels for load bearing, and adhesive materials, serve as a source of inspiration for innovative and sustainable design practices. The pedicels in Asian hornet nests play a crucial role in transferring load and ensuring stability. Additionally, AHNs' adhesion to tree branches is essential for preventing collapse, and the pedicels provide necessary structural support. The knowledge gained from studying AHNs' internal architecture could be applied directly to the architecture and civil engineering fields to improve structure stability and durability. The microstructure analysis of the paper-like material that hornets produce to build their nests indicates a complex and heterogeneous structure, composed of various plant fragments and fibres. This unique composition creates intricate grooves and pores, which are essential for regulating temperature and humidity levels within the outer envelope of the nest. The study of Asian hornet nests' internal structure demonstrated that nature's engineering principles inspire the design of durable and resilient structures in the construction industry. Civil engineers can incorporate similar principles into their designs to enhance the structural integrity and performance of buildings, bridges, and other infrastructure.

Abstract
The Douro Demarcated Region (DDR) has peculiar edaphoclimatic characteristics that provide a suitable terroir for premium wine production. As climate change effects continue to emerge, ensuring productivity and quality becomes increasingly important for viticulturists, as those directly determine their profits. Cultural approaches, such as the use of biostimulants, are actively being developed to mitigate abiotic stress. The main objective of this work was to assess the effect of foliar sprays of a seaweed (Ascophyllum nodosum)-based extract (ANE) and glycine betaine (GB) on grape berry quality, bioactive compounds, and antioxidant activity. A trial was installed in a commercial vineyard (cv. 'Touriga Franca') in the Douro Superior (Upper Douro) sub-region of the Douro Demarcated Region. In 2020 and 2021, three foliar sprayings were performed during the growing season, namely at pea size, bunch closure, and veraison. There was a positive effect of both biostimulants (ANE and GB) on the physiological and biochemical performance of cv. 'Touriga Franca' exposed to summer stress. In general, the GB 0.2% spraying was the most promising treatment for this grape cultivar, as it increased berry quality, the concentration of bioactive compounds (total phenolics, flavonoids, and ortho-diphenols), and the antioxidant activity. These results revealed the efficacy of biostimulant sprayings as a sustainable viticultural practice, improving berry quality under summer stress conditions.

Abstract
PURPOSE/OBJECTIVE(S) We aimed to establish the added value of combining dosimetry with a binary blood assay for radiosensitivity based on quantification of pATM protein (RADIODTECT©) to predict acute radiotherapy (RT) induced mucositis (MUC) and dysphagia (DYS) in head & neck cancer patients (pts). MATERIALS/METHODS We enrolled 101 pts prospectively scored for acute toxicity with CTCAE. We considered four endpoints: grade≥2 (G2+) and grade≥3 (G3+) MUC, G2+, and G3+ DYS. We dichotomized the pATM concentration to define radiosensitive (RS) vs. radioresistant (RR) pts using previously described cutoffs for G2+ (57.8 ng/mL) and G3+ toxicity (46 ng/mL). We did RADIODTECT© and toxicity scoring blindly. We considered two already published NTCP models, including (i) the Equivalent Uniform Dose to the oral cavity (n = 0.05, EUD_OC, Odds Ratio [OR] = 1.02) and the mean dose to the parotid glands (Dmean_PG, OR = 1.06) for MUC and (ii) EUD_OC (OR = 1.04), the glottic larynx EUD (n = 0.35, EUD_GL, OR = 1.02) and the volume of pharyngeal constrictor muscles receiving>50Gy (V50Gy_CM, OR = 1.02) for DYS. To account for the association of toxicity with the dose distribution in multiple organs at risk (OARs), we derived a "Weighted Dose Score" (WDS) as a linear combination of the dose factors, using their β-coefficients (= lnOR) as weights. WDS for MUC (WDS_OM) = 0.06*Dmean_PG + 0.02*EUD_OC WDS for DYS (WDS_DYS) = 0.02*V50Gy_CM + 0.02*EUD_GL + 0.04*EUD_OC We used WDS as a comprehensive dose feature to fit a dose response and allowed WDS50 (i.e., the WDS associated with 50% toxicity probability) to be different for RR (WDS50_RR) and RS pts (WDS50_RS). The dose-modifying factor (DMF) is the ratio of WDS50_RS/WDS50_RR. It measures the horizontal shift of the dose-response curve when comparing RS vs. RR pts. RESULTS We scored G2+ and G3+ MUC in 80 and 41 pts; G2+ and G3+ DYS in 73 and 35 pts. The average concentration of pATM was 57.4ng/mL (sd 22.3ng/mL): 53/101 pts were classified as RS for G2+ toxicity and 35/101 as RS for G3+. On the whole cohort, the RADIODTECT© did not significantly associate with the risk of toxicity. However, we found two different dose-response curves at low WDS. There, the intrinsic biological sensitivity significantly affects the toxicity probability: ORs for RADIODTECT© are 2.6/2.4 for G2+/G3+ DYS, 6.4/2.9 for G2+/G3+ MUC. Furthermore, the difference in the incidence of side effects in RR vs. RS pts decreases as the WDS increases, reaching a region where the doses of OARs play a significant role. When combined with WDS, the RADIODTECT© effectively predicted RS pts, with DMF ranging from 0.77 for G3+ DYS to 0.40 for G2+ MUC. CONCLUSION These findings support the hypothesis that dose and biomarkers act synergistically; biologically based radiosensitivity plays a significant role when OARs are exposed at lower doses, while high doses of OARs determine toxicity irrespective of the underlying single pt biological characterization.

Abstract
Antipsychotics (APs) are the cornerstone of treatment for schizophrenia (SCZ) spectrum disorders. Previous research suggests that there may be a positive association between AP-induced weight gain and/or dyslipidemia and improvement in psychiatric symptoms, often referred to as a "metabolic threshold". To determine whether a similar relationship exists for glucose parameters, we conducted a systematic search in six databases from inception to June 2022 for all longitudinal studies that directly examined the relationship between changes in glucose-related outcomes and changes in psychopathology among patients with SCZ treated with APs. We identified 10 relevant studies and one additional study that considered cognition. In most cases, we found that increased levels of fasting glucose and insulin following treatment were associated with clinical improvement. These findings contribute to existing literature that could suggest a common mechanism between AP action and metabolic side effects and support a need for additional work aimed at exploring the validity of a glucose-psychopathology relation in SCZ.

Abstract
Background Although the use of neuromuscular blocking agents (NMBAs) optimizes surgical conditions and facilitates tracheal intubation, it can lead to residual neuromuscular blockade (RNMB), with postoperative complications. This study aimed to assess RNMB incidence and management in Portugal. Methods Prospective observational study of patients admitted for elective surgery requiring general anesthesia with nondepolarizing NMBAs between July 2018 and July 2019 at 10 Portuguese hospitals. The primary endpoint was the proportion of patients arriving at postanesthesia care unit (PACU) with a TOF ratio <0.9. Results A total of 366 patients were included, with a median age of 59 years, and 89.1% classified as ASA II or III. Rocuronium was the most used NMBA (99.5%). A total of 96.2% of patients received a reversal agent, 96.6% of which sugammadex and 3.4% neostigmine. Twenty patients displayed a TOF ratio <0.9 at PACU arrival, representing an RNMB incidence of 5.5% (95% CI, 3.1%-7.8%). Only two patients displayed a TOF ratio <0.7. RNMB incidence was 16.7% with neostigmine and 5.3% with sugammadex (P = .114). In patients with intraoperative neuromuscular blockade (NMB) monitoring, RNMB incidence was 5% (95% CI, 2%-8%), which varied significantly according to the type of monitoring (P = .018). Incidence of adverse events was 3.3% (2 severe and 10 moderate). Conclusions The reported overall incidence of 5.5% is numerically lower than results from similar observational studies. An appropriate pharmacological neuromuscular reversal strategy, guided by quantitative neuromuscular monitoring, has the potential to achieve even better results, converting RNMB from an unusual to a very rare or even inexistent event.

Abstract
ConspectusN-Acetylgalactosamine (GalNAc)-type O-glycosylation is an essential posttranslational modification (PTM) that plays fundamental roles in biology. Malfunction of this PTM is exemplified by the presence of truncated O-glycans in cancer. For instance, the glycoprotein MUC1 is overexpressed in many tumor tissues and tends to carry simple oligosaccharides that allow for the presentation of different tumor-associated antigens, such as the Tn or sTn antigens (GalNAc-α-1-O-Thr/Ser and Neu5Acα2-6GalNAcα1-O-Ser/Thr, respectively). In other cases, such as tumoral calcinosis associated with O-glycosylation of the fibroblast growth factor 23, O-glycans are absent or less abundant. Significant progress has been made in determining the three-dimensional structures of biomolecules that recognize GalNAc, such as antibodies, lectins, mucinases, GalNAc-transferases, and other glycosyltransferases. Analysis of the complexes between these entities and GalNAc-containing glycopeptides, in most cases derived from crystallographic or NMR analysis, provides an understanding of the key structural elements that control molecular recognition of these glycopeptides. Here, we describe and compare the binding sites of these proteins in detail, focusing on how the GalNAc moieties interact selectively with them. We also summarize the differences and similarities in GalNAc recognition. In general, the recognition of GalNAc-containing glycopeptides is determined by hydrogen bonds between hydroxyl groups and the N-acetyl group of GalNAc with proteins, as well as CH-π contacts in which the hydrophobic α-face of the sugar and the methyl group of NHAc can be involved. The latter interaction usually provides the basis for selectivity. It is worth noting that binding of these glycopeptides depends primarily on recognition of the sugar moiety, with some exceptions such as a few anti-MUC1 antibodies that primarily recognize the peptide backbone and use the sugar to facilitate shape complementarity or to establish a limited number of interactions with the protein. Focusing specifically on the GalNAc moiety, we can observe that there is some degeneracy of interactions within the same protein families, likely due to substrate flexibility. However, when all studied proteins are considered together, despite the commonalities within each protein family, no pattern can be discerned between the different families, apart from the presence of common residues such as Tyr, His, or Asp, which are responsible for hydrogen bonds. The lack of a pattern can be anticipated, given the diverse functions of mucinases, glycosyltransferases, antibodies, and lectins. Finally, it is important to point out that the conformational differences observed in solution in glycopeptides bearing GalNAc-α-1-O-Ser or GalNAc-α-1-O-Thr also can be found in the bound state. This unique characteristic is exploited, for instance, by the enzyme C1GalT1 to broadly glycosylate both acceptor substrates. The findings summarized in this review may contribute to the rational structure-guided development of therapeutic vaccines, novel diagnostic tools for early cancer detection, and new cancer treatments for cancer with tailored anti-Tn or anti-STn antibodies or new drugs to inhibit GalNAc-T isoenzymes.

Abstract
This study aimed to identify the variables associated with fixation failure in intertrochanteric fractures treated with cephalomedullary nailing (CMN). We retrospectively analyzed 251 consecutive patients who underwent surgery between January 2016 and July 2019. In order to identify predictors of failure (cut-out, cut-through, and/or nonunion), we analyzed: gender, age, fracture stability (according to the AO/OTA Classification), femoral neck angle (FNA), FNA as compared to the contralateral hip, lag screw position, and tip-apex distance (TAD). The failure rate was 9.6%: there were 10 cut-outs (4%), 7 non-unions (2.8%), and 7 cut-throughs (2.8%). Univariate logistic regression analysis showed that the risk factors for fixation failure were: female sex (p= 0.018), FNA <125° (p= 0.003), a difference in FNA of 7.5° as compared to the contralateral hip on the lateral radiograph (p= <0.0001), superior (p= 0.0141) and anterior position (p= <0.0001) of the lag screw, and TAD >25mm (p= 0.016). According to the multivariate analysis, female gender (OR 12.92 ; p 0.0019), the difference in FNA on the lateral view (OR 1.36; p < 0.001), and the anterior position of the screw in the femoral head (OR14.01;p <0.001) were confirmed as independent predictors of failure. In order to avoid failures in intertrochanteric hip fractures treated with CMN, this study confirmed the importance of achieving an accurate reduction on the lateral plane and avoiding the anterior position of the screw on the femoral head.

Abstract
Schizophrenia is a debilitating psychiatric disorder that is treated with antipsychotics. However, despite their efficacy, antipsychotics increase the risk of metabolic disorders in a population that suffers from premature cardiovascular death. Published reports to date strongly suggest that antipsychotic-induced alterations in lipid metabolism are part of the causal relationship between antipsychotic treatment and both metabolic and cardiovascular disease. Notably, some of the adverse effects of antipsychotics on lipid metabolism are independent of antipsychotic-induced weight gain. Moreover, some antipsychotics also have beneficial effects on certain aspects of lipid metabolism. In this review, we summarize the current knowledge regarding how antipsychotics modulate lipid turnover at the whole-body, tissue, and cellular levels. We also highlight gaps in the literature, especially with respect to the intracellular mechanisms through which antipsychotics affect lipid metabolism.

Abstract
Orchard net cover improves plant physiology, yield and fruit quality, pest and disease control, and anticipates fruit ripening. Moreover, this crop technology has been used to reduce natural cherry cracking (NCC). This is a serious physiological disorder that cracks the epidermis, the hypodermis, and the storage parenchyma layers of the fruit due to rainfall events near the harvest and it is related to low fruit osmotic potential and/or high fruit water permeability. This work aims to study the effect of orchard net cover on sweet cherry trees, cv. Early Bigi, in two harvesting years (2019 and 2021). The NCC, the induced cracking index (CI), and the cracking type incidence were determined. In addition, epicuticular and intra-cuticular wax content, biometric and physicochemical parameters were also evaluated. Net cover reduced the natural cracking index by 40%. High fruit weight values were observed in covered trees comparing to the control ones, with increases of 45% and 13%, in 2019 and 2021, respectively. A positive correlation was observed between CI and total soluble solids and a negative correlation between CI and wax content. Therefore, with forecasts of worsening heavy precipitation events near harvest, protecting cherry trees with nets will increase resistance to fruit cracking.

Abstract
SUMMARY
Purpose
The purpose of this evaluation was to evaluate the vertical marginal discrepancies of a computer-aided design-computer-aided manufacture (CAD-CAM) system used by different providers at separate time intervals.
Methods and Materials
Lithium disilicate monolithic crowns on mandibular third molars were fabricated by three different providers inexperienced in digital dentistry. Using a precision rotary stage mounted on a digital recording microscope, the crown vertical marginal discrepancy was assessed using 160× magnification at 5-degree intervals around the crown marginal circumference for a total of 72 measurements per specimen. In addition to mean vertical marginal discrepancy, the maximum vertical marginal discrepancy, and its location as well as the percent of closed marginal assessments, were assessed. Mean data was analyzed using Kruskal–Wallis and Dunn post hoc testing at a 95% level of confidence (α=0.05).
Results
The mean marginal vertical discrepancy for all specimens was 21.1 ± 5.5 μm and a significant difference (p=0.0016) existed between groups but with noted wide similarity overlap. No difference (p=0.65) was observed with the mean closed margin percentage, but a significant difference (p=0.0012) existed in the observed maximum marginal discrepancy between groups. The 2-mm axial wall height (AWH), 20-degree total occlusal convergence (TOC) had significantly less (p<0.017) mean vertical marginal discrepancies than the 4-mm AWH, 20-degree TOC, and the 3-mm AWH, 16-degree TOC groups with the remaining groups similar (p>0.147). The plotted location of the specimen’s maximum vertical discrepancy suggests a potential pattern amid the 360-degree margin circumference.
Conclusions
Under the conditions of this study, CAD-CAM-derived monolithic lithium disilicate ceramic crowns fabricated by different clinicians demonstrated mean vertical marginal discrepancy results that were less than the suggested maximum clinically acceptable values. A potential for patterns of marginal discrepancy results was identified and deserves further evaluation. Results should be interpreted with caution as in vitro methodologies vary and do not directly correlate with clinical conditions.

Abstract
Recent advances in developing polygenic scores have made it possible to screen embryos for common, complex conditions and traits. Polygenic embryo screening (PES) is currently offered commercially, and though there has been much recent media and academic coverage, reproductive specialists' points of view have not yet been prominent in these discussions. We convened a roundtable of multidisciplinary experts, including reproductive specialists to discuss PES and its implications. In this Opinion, we describe four clinically relevant issues associated with the use of PES that have not yet been discussed in the literature and warrant consideration.

Abstract
Introduction The concept of cycloid psychosis has a long tradition in European psychiatry since it was introduced by Kleist in 1926. Nevertheless, this concept is not included explicitly in modern classifications, leading to a controversial discussion about its utility in current psychiatry. Objectives Starting from a case study, we intend to review the evolution of cycloid psychosis concept and analyze its role in modern psychiatry. Methods Non-systematic review of the literature and report of a case study. Results Following Kleist’s work, Leonhard described the three overlapping subtypes, and later Perris developed the first operational diagnostic criteria. Since then, this entity has shown a high diagnostic stability, validity and a good predictive diagnostic and prognostic value. We report a case of a 30-year-old woman, previous heathy, without regular medication, living with her parents and 5-year-old son, until she emigrated alone to Switzerland. After 10 days abroad, she was sent back to Portugal, and after organic disease and drug misuse exclusion, she was admitted in our inward with a clinical picture of perplexity, anxiety, thinking and behavioral disturbance with persecutory and poisoning delusions, auditory hallucinations, and total insomnia. Following rapid and full recovery, she was discharged 14 days later while being medicated with Paliperidone 3 mg/day and Lorazepam 4 mg/day, which was abandoned by her 2 months later, without relapse of the symptoms. Conclusions The current lack of a satisfactory system for categorizing acute, and remittent psychoses seems to be reason enough to remain awareness of this unique diagnostic entity, which is worthy of further investigation. Disclosure No significant relationships.

Introduction
The impact of acute infection by SARS-COV2 on the cardiovascular system has been previously reported in the literature, with a higher propensity in patients with more serious pattern of disease and pro-inflammatory status. Nevertheless, the long-term burden and sequels of COVID-19 on the cardiovascular system is still unknown.
Purpose
To evaluate the long-term impact of COVID-19 on left ventricular function in patients with severe clinical presentation requiring intensive care hospitalization.
Methods
This was a single-center observational, prospective study which included patients requiring admission to the Intensive Care Unit (ICU) due to COVID-19 infection from January to November 2020. All discharged patients were contacted to perform a clinical, electrocardiographic and echocardiographic evaluation and those who accepted were included on the protocol. Baseline and clinical characteristics were collected from clinical reports. For the global longitudinal strain (GLS) analysis all patients with significant wall motion abnormalities and valvular cardiopathy were excluded. Statistical analysis was performed with Mann-Whitney and a safety cut-off was established with ROC curve analysis.
Results
A total of 43 patients were included (mean age 64 ± 12, 67.4% males). During SARS-COV2 infection 49% presented with severe ARDS and 51% with moderate, 35% required invasive mechanical ventilation, 14% noninvasive mechanical ventilation and 52% with high nasal flow cannula. On the follow-up analysis, fatigue was the most reported in symptom (52% patients) and the majority did not present other signs or symptoms suggestive of heart failure, with the mean NT-proBNP of 49 ± 389 pg/dL. The standard ECG and echocardiogram did not show significant changes with a mean LVEF of 58 ± 7.8 and mean TAPSE of 21 ± 4. The strain analysis showed low value of GLS (mean GLS of -17.14 ± 2.36) for a reference cut-off of -18%, suggesting subclinical left ventricular dysfunction in this subset of patients with preserved ejection fraction. Maximum CPR values during ICU did not correlate either with the extent of disease evolvement in CT (p= NS) or ARDS severity (p= NS). Nevertheless, maximum CPR correlated significantly with GLS reduction (R = 0.44, p = 0.019). A CPR value higher than iger30mg/dL had 100% specificity for GLS reduction and a cut-off of 14gm/dL reported a sensitivity of 65% and specificity pf 75% for reduction in GLS.
Conclusion
In our study, we reported subclinical impairment in left ventricular function detected with global longitudinal strain after serious infection with SARS-COV2. The detected myocardial dysfunction was related with higher inflammatory as expressed by CPR values. Long-term monitoring of these patients should be undertaken in order to timely detect late complications. Abstract Figure.

Abstract
The NAD-dependent deacetylase SIRT1 improves β cell function. Accordingly, nicotinamide mononucleotide (NMN), the product of the rate-limiting step in NAD synthesis, prevents β cell dysfunction and glucose intolerance in mice fed a high-fat diet. The current study was performed to assess the effects of NMN on β cell dysfunction and glucose intolerance that are caused specifically by increased circulating free fatty acids (FFAs). NMN was intravenously infused, with or without oleate, in C57BL/6J mice over a 48-h-period to elevate intracellular NAD levels and consequently increase SIRT1 activity. Administration of NMN in the context of elevated plasma FFA levels considerably improved glucose tolerance. This was due not only to partial protection from FFA-induced β cell dysfunction but also, unexpectedly, to a significant decrease in insulin clearance. However, in conditions of normal FFA levels, NMN impaired glucose tolerance due to decreased β cell function. The presence of this dual action of NMN suggests caution in its proposed therapeutic use in humans.

Abstract
miRNAs have crucial functions in many biological processes and are candidate biomarkers of disease. Here, we show that miR-216a is a conserved, pancreas-specific miRNA with important roles in pancreatic islet and acinar cells. Deletion of miR-216a in mice leads to a reduction in islet size, β-cell mass, and insulin levels. Single-cell RNA sequencing reveals a subpopulation of β-cells with upregulated acinar cell markers under a high-fat diet. miR-216a is induced by TGF-β signaling, and inhibition of miR-216a increases apoptosis and decreases cell proliferation in pancreatic cells. Deletion of miR-216a in the pancreatic cancer-prone mouse line KrasG12D;Ptf1aCreER reduces the propensity of pancreatic cancer precursor lesions. Notably, circulating miR-216a levels are elevated in both mice and humans with pancreatic cancer. Collectively, our study gives insights into how β-cell mass and acinar cell growth are modulated by a pancreas-specific miRNA and also suggests miR-216a as a potential biomarker for diagnosis of pancreatic diseases.

Abstract
The accumulation of marine biofouling on ship hulls causes material damage, the spread of invasive species, and, indirectly, an increase in full consumption and subsequent pollutant gas emissions. Most efficient antifouling (AF) strategies rely on the conventional release of persistent, bioaccumulative, and toxic biocides incorporated in marine coatings. A simple oxygenated xanthone, 3,4-dihydroxyxanthone (1), was previously reported as a promising AF agent toward the settlement of Mytilus galloprovincialis larvae, with a therapeutic ratio higher than the commercial biocide Econea®. In this work, a structure-AF activity relationship study, an evaluation of environmental fate, and an AF efficiency in marine coatings were performed with compound 1. Hydroxy or methoxy groups at 3 and 4 positions in compound 1 favored AF activity, and groups with higher steric hindrances were detrimental. Compound 1 demonstrated low water-solubility and a short half-life in natural seawater, contrary to Econea®. In silico environmental fate predictions showed that compound 1 does not bioaccumulate in organism tissues, in contrast to other current emerging biocides, has a moderate affinity for sediments and slow migrates to ground water. No toxicity was observed against Vibrio fischeri and Phaeodactylum tricornutum. Polyurethane-based marine coatings containing compound 1 prepared through an innovative non-release-strategy were as efficient as those containing Econea® with low releases to water after 45 days. This proof-of-concept helped to establish compound 1 as a promising eco-friendly AF agent.

Abstract
Abstract
Background/Objective
Up to 30% of patients with cancer may present cognitive impairment (CI) before treatment but data are scarce regarding prostate cancer (PCa). We aim to estimate the prevalence of CI in patients with PCa, before cancer treatment.
Methods
Between February 2018 and April 2021, the NEON-PC cohort included 609 patients with a recent PCa diagnosis to be treated at Instituto Português de Oncologia do Porto. Previous history of chemotherapy, radiotherapy, androgen deprivation therapy, and neurologic or psychyatric conditions impairing cognitive performance were exclusion criteria. The Montreal Cognitive Assessment (MoCA) was used to assess cognitive performance before any treatment for PCa. Participants with a MoCA at least 1.5 SD below age- and education-specific norms were considered to have probable cognitive impairment (PCI) and were proposed for a comprehensive neuropsychological (NP) assessment. Participants scoring <2.0 SD age-corrected norms in at least one cognitive test, or < 1.5 SD age-corrected norms in ≥ 2 cognitive tests were classified as having CI. Data from the population-based cohort EPIPorto (n = 351 men, evaluated in 2013-2015) were used for comparison.
Results/Discussion
Prevalence of PCI was 17.4% in the EPIPorto and 15.1% in the NEON-PC cohort (age- and education-adjusted OR = 1.02,95% confidence interval: 0.70,1.50). NP assessment was performed in 65 patients with PCa: 38.5% had normal cognitive function; 7.7% had a light deficit (<1.0 SD of age-corrected norms in ≥ 1 cognitive tasks); and 53.9% had CI.
Conclusions
PCI was as frequent in patients recently diagnosed with PCa as in the general population. Prevalence of CI was lower than in previous reports, which may be explained by differences in the assessment and definition of CI and of the type of cancer.

Key messages
Patients with prostate cancer and the general population had similar odds of having a score below normative values in the MoCA. Differences in the prevalence of CI between this study and others suggest that the type of cancer may affect patients’ cognitive performance differently, which deserves further confirmation.

Abstract
Background/Objective
Androgen deprivation therapy (ADT) has been associated with cognitive decline, but results have been heterogenous. We describe changes in cognitive performance in patients with prostate cancer (PCa), according to treatment with ADT, during the 1st year after PCa diagnosis.
Methods
Between February 2018 and March 2021, 348 patients with PCa treated at the Instituto Português de Oncologia do Porto were evaluated with the Montreal Cognitive Assessment (MoCA), before treatment and after one year (1y). ADT was used in 183 participants, and 165 were treated without ADT (total prostatectomy, radiotherapy, brachytherapy, active surveillance). Cognitive decline was defined as the decrease in MoCA from baseline to the 1y-evaluation below 1.5SD of the distribution of the MoCA variation in the whole cohort. Participants scoring below age- and education-based normative reference values in MoCA were considered to have probable cognitive impairment (PCI). Multivariate logistic regression was used to estimate age- and education-adjusted OR (aOR) of the association between ADT and cognitive decline/incident PCI.
Results/Discussion
PCI was observed in 12.4% of the patients at baseline. Mean MoCA scores increased from baseline to the 1y-evaluation (22.4 vs. 22.9, p = 0.001), and 51.2% of PCI cases at baseline had normal MoCA scores at 1y. Cognitive decline was most frequent in the ADT group (9.3% vs. 3.6%, p = 0.034), although the aOR was 2.44 (95%CI:0.89-6.71). The 1yr cumulative incidence of PCI was 10.4% (95%CI:6.2%-16.2%) in the ADT-group and 2.8% (95%CI:0.8-%-7.1%) in the non-ADT group [aOR=3.15 (95%CI:0.97-10.25)].
Conclusions
ADT was associated with a decrease in the cognitive performance of PCa patients during the 1st year after diagnosis. The completion of the 1y-evaluation in the whole cohort (n = 600) is needed to confirm these preliminary results.

Key messages
Half of the cases with cognitive impairment at baseline improved at one-year. Patients treated with ADT seem to be affected by cognitive decline more frequently.

Abstract
Abstract
Introduction
The 2016 European Society of Cardiology Heart Failure Guidelines (2016 HF GL) suggest sequential therapy initiation with angiotensinogen converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB), beta-blocker (BB) and mineralocorticoid receptor antagonist (MRA) for patients with heart failure with reduced ejection fraction (HFrEF). Since their publication, major trials established the benefit of sacubitril/valsartan (ARNi) and SGLT2 in HFrEF, and ARNi are suggested to replace ACEi/ARB as first line therapy. So, with HFrEF foundational therapy evolvement, the 2016 HF GL sequential therapy initiation algorithm has been raised into question.
Purpose
To compare in the real-world practice, the effect on all-cause mortality of the simultaneous use of every pharmacological class currently included in the HFrEF foundational therapy with conventional sequential therapy.
Methods
A population of consecutive patients (pts) included in a post-discharge structured follow-up programin in a tertiary center was analyzed. Two groups were defined: 1) patients medicated with all pharmacological classes considered the HFrEF foundational therapy (ARNi, BB, MRA and SGLT2 inhibitor), independently of the dosages – “FT group”; 2) patients medicated with ACEi/ARB, BB and MRA on maximal tolerated doses – “2016 HF GL group”. Pts under other therapeutical combinations were excluded. The study groups were compared with Chi-square and Mann-Whitney tests. Impact on all-cause mortality was established with Kaplan-Meier survival analysis and multivariate Cox regression after adjustment for age, sex and baseline creatinine, NYHA functional class and LVEF.
Results
From 2016 to February 2021, a total of 101 pts with HFrEF were included and followed for 25±16 months. 54 pts were included in the FT group and 47 in the 2016 HF GL. The study population (69.3% males, 64.6±11.4 years) were mainly in NYHA functional class II (48%) and III (48%). The most common HF aethiologies were ischemic heart disease (49.5%) and dilated cardiomyopathy (30.7%), median LVEF was 26% and 22% were under CRT. Baseline characteristics were similar between groups, except for diabetes (more common in FT group, 70 vs 22%, p<0.001). All-cause mortality rate during follow-up was significantly different between two groups: 1.9% in FT group and 17% in the HF GL group (p: 0.047) – Figure 1. The implementation of all foundational therapy classes was an independent protective factor for all-cause mortality (HR 0.41; IQR 0.004–0.468; P: 0.010) in multivariate Cox regression.
Conclusion
This real-world study suggests that conventional sequential therapy suggested by the 2016 HF GL may be less effective on reducing all-cause mortality in HFrEF than simultaneous use of all pharmacological classes that nowadays compose the foundation therapy. These results support the hypothesis of promoting early introduction of all therapy classes followed by a tailored uptitration may be beneficial.

Abstract
The effects of climate change are increasingly noticed worldwide, and crops are likely to be impacted in direct and indirect ways. Thus, it is urgent to adopt pliable strategies to reduce and/or mitigate possible adverse effects to meet the growing demand for sustainable and resilient food production. Monoculture cropping is globally the most common production system. However, adaptation to ongoing climate change, namely, to more extreme environmental conditions, has renewed the interest in other practices such as agroforestry, agroecology, and permaculture. This article provides an overview of ecological and physiological interactions between trees and crops in Mediterranean agroforestry systems and compares them with those from monocultures. The advantages and disadvantages of both systems are explored. The added value of modeling in understanding the complexity of interactions within agroforestry systems, supporting decision-making under current and future weather conditions, is also pinpointed. Several interactions between trees and crops might occur in agroforestry systems, leading to mutual positive and/or negative effects on growth, physiology, and yield. In this sense, selecting the most suitable combination of tree/crop species in mixtures may be best be indicated by complementary traits, which are crucial to maximizing trade-offs, improving productivity, ecosystem services, and environmental sustainability.

Abstract
Although innate immunity is linked to metabolic health, the effect of leptin signaling in cells from the innate immune system on glucose homeostasis has not been thoroughly investigated. We generated two mouse models using Cre-lox methodology to determine the effect of myeloid cell-specific leptin receptor (Lepr) reconstitution and Lepr knockdown on in vivo glucose metabolism. Male mice with myeloid cell-specific Lepr reconstitution (Lyz2Cre+LeprloxTB/loxTB) had better glycemic control as they aged compared to male mice with whole-body transcriptional blockade of Lepr (Lyz2Cre−LeprloxTB/loxTB). In contrast, Lyz2Cre+LeprloxTB/loxTB females only had a trend for diminished hyperglycemia after a prolonged fast. During glucose tolerance tests, Lyz2Cre+LeprloxTB/loxTB males had a mildly improved plasma glucose profile compared to Cre− controls while Lyz2Cre+LeprloxTB/loxTB females had a similar glucose excursion to their Cre− controls. Myeloid cell-specific Lepr knockdown (Lyz2Cre+Leprflox/flox) did not significantly alter body weight, blood glucose, insulin sensitivity, or glucose tolerance in males or females. Expression of the cytokine interleukin 10 (anti-inflammatory) tended to be higher in adipose tissue of male Lyz2Cre+LeprloxTB/loxTB mice (p = 0.0774) while interleukin 6 (pro-inflammatory) was lower in male Lyz2Cre+Leprflox/flox mice (p < 0.05) vs. their respective controls. In conclusion, reconstitution of Lepr in cells of myeloid lineage has beneficial effects on glucose metabolism in male mice.

Abstract
Plasma free fatty acids (FFAs) are elevated in obesity and can induce insulin resistance via endoplasmic reticulum (ER) stress. However, it is unknown whether hepatic insulin resistance caused by the elevation of plasma FFAs is alleviated by chemical chaperones. Rats received one of the following i.v. treatments for 48 h: saline, intralipid plus heparin (IH), IH plus the chemical chaperone 4-phenylbutyric acid (PBA), or PBA alone and a hyperinsulinemic-euglycemic clamp was performed during the last 2 h. PBA co-infusion normalized IH-induced peripheral insulin resistance, similar to our previous findings with an antioxidant and an IκBα kinase β (IKKβ) inhibitor. Different from our previous results with the antioxidant and IKKβ inhibitor, PBA also improved IH-induced hepatic insulin resistance in parallel with activation of Akt. Unexpectedly, IH did not induce markers of ER stress in the liver, but PBA prevented IH-induced elevation of phosphorylated eukaryotic initiation factor-2α protein in adipose tissue. PBA tended to decrease circulating fetuin-A and significantly increased circulating fibroblast growth factor 21 (FGF21) without affecting markers of activation of hepatic protein kinase C-δ or p38 mitogen-activated protein kinase that we have previously involved in hepatic insulin resistance in this model. In conclusion: (i) PBA prevented hepatic insulin resistance caused by prolonged plasma FFA elevation without affecting hepatic ER stress markers; (ii) the PBA effect is likely due to increased FGF21 and/or decreased fetuin-A, which directly signal to upregulate Akt activation.

Introduction
Pulmonary embolism (PE) is a recognized complication of SARS-COV2 infection due to hypercoagulability. Before the COVID era, the need for computed tomography pulmonary angiography (CTPA) to rule out PE was determined by clinical probability, based on Wells and Geneva scores, in association with D-dimer measurements. However, patients with SARS-COV2 infection have a pro-thrombotic and pro-inflammatory state which may compromise the usefulness of these algorithms to select patients for CTPA.
Purpose
To evaluate the accuracy of the Wells and Geneva scores to predict PE in patients with SARS-COV2 infection.
Methods
Retrospective study of consecutive outpatients with SARS-COV2 infection proved by positive PCR who underwent CTPA due to suspected PE. The Wells and Geneva scores were calculated and the area under the curve (AUC) of the receiver operating characteristic curve was measured.
Results
We enrolled 235 patients (61% males, mean age 69.10 ± 16.69 years) and the incidence of pulmonary embolism was 15% (35 patients). In patients with PE, emboli were located mainly in segmental arteries (60%) and bilaterally (46%). Patients with PE were older (mean age 75.06 ± 2.23 vs. 68.06 ± 1.21 years, p = 0.022), and did not differ in sex or risk factors for thromboembolic diseases from the non-PE group. Patients with PE had higher D-dimer levels (median 15.41 mg/dl, IQR 1.17 – 20.00) compared to patients without PE (median 5.99 mg/dl, IQR 0.47 – 2.82, p < 0.001).
There was no statically significant difference between the average Wells score in patients with PE and without PE (1.04 and 0.89 respectively, p = 0.733) and the AUC demonstrated that the Wells score had no discriminatory power (AUC = 0.52). Within patients with PE, 19 patients had a Wells score of zero. Regarding the Geneva score, there was also no difference between the average score in patients with and without PE (4.20 vs 3.93 respectively, p = 0.420). AUC for Geneva score was 0.54.
Clinical probability combined with D-dimer measurement had a 100% sensitivity for both Wells and Geneva scores, but a specificity of 10% and 11%, respectively.
Conclusion
PE diagnosis may be challenging in patients with SARS-COV2 infection since both conditions may have similar signs and symptoms and may be associated with increased D-dimers. According to our results, traditional clinical prediction scores have little discriminatory power in these patients and a higher D-dimer cut-off should be considered to better select patients for CTPA to minimize radiation exposure and contrast-related complications in COVID-19 patients.

Abstract
INTRODUCTION The tibial plateau fractures due to high-energy mechanisms are serious injuries that occur on a load bearing joint. These are difficult to approach because, also affect the bone structure of the leg, they usually have associated soft tissue injuries. OBJECTIVE To evaluate the radiological and functional results of high-energy tibial plateau fractures with a minimum follow-up of one year. MATERIAL AND METHODS Retrospective, observational and multicenter study. Analysis of radiological and functional outcomes in the treatment of high-energy tibial plateau fractures, treated by open reduction and internal fixation (ORIF) between 2014 and 2019. RESULTS 54 fractures treated by ORIF. Follow-up one year. 98.1% consolidation in 13 weeks on average. 83.4% without alterations of the axis in the coronal plane. 74% without postoperative joint widening. Functional scores: Lysholm 82.1 average points and Oxford Knee Score (OKS) 39.5 average points. CONCLUSION The joint range of motion was reduced after a high-energy tibial plateau fracture, but with good functional results. The less off axis and less post-operative radiographic widening, the better results are obtained.

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.

Introduction
Discharge after overnight hospital stay is standard procedure in patients submitted to elective atrial fibrillation (AF) ablation. Taking into consideration the low rate of cryoablation procedure complications could the same day discharge be an option?
Purpose
To access the safety of same day discharge of patients submitted to AF cryoablation.
Methods
Single-center retrospective study of consecutive pts admitted to elective AF cryoablation in a tertiary center between February 2017 and November 2020. Patients were divided into two groups: same day discharge and next day discharge. Only patients submitted to ablation until 4 p.m. were included. Complication rates were obtained up to six months after the procedure. Complications were defined as death, pericardial tamponade, hematoma requiring evaluation and/or intervention, major bleeding requiring transfusion, hospital admission related to the procedure.
Results
One hundred fifty-four pts were included, with a mean age of 61 ± 10.9 years, 66.2% were males, 18.2% with diabetes, 65.6% with dyslipidemia, 77.9% with hypertension, 10.4% with chronic kidney disease KDIGO stage 3 or more. Median follow-up of 436 (IQ 178 – 729) days. Most of the pts had paroxysmal (73.4%) and persistent short duration AF (23.4%). Sixty-two pts (40.3%) were early discharged and there were no differences between the two groups regarding epidemiological and clinical characteristics (p = NS).
A very low rate of complications in both groups was observed, occurring in 6.5% of pts with early discharge and in 8.7% of pts in overnight stay, without statistical significance between the two groups (p = 0.61). The most frequent complications were local hematoma (5 pts, 2 in early discharged group), pericardial effusion (3 pts, all in overnight stay), femoral pseudo-aneurism (2 pts, 1 in each group) and arteriovenous fistula (1 pt in overnight stay group). The type of complications did not differ between the two groups (p = 0.51). Two pts died during the follow up, unrelated with the procedure.
In addition, no difference in success rate and arrhythmic recurrence was observed between the two groups. (p = NS)
Conclusion
Our study suggests that is safe to early discharge pts submitted to AF ablation, reducing the hospital stay length in selected pts. Larger studies are needed to confirm this data before routine implementation of this strategy.

Abstract
There is general agreement that the acute suppression of hepatic glucose production by insulin is mediated by both a direct and an indirect effect on the liver. There is, however, no consensus regarding the relative magnitude of these effects under physiological conditions. Extensive research over the past three decades in humans and animal models has provided discordant results between these two modes of insulin action. Here, we review the field to make the case that physiologically direct hepatic insulin action dominates acute suppression of glucose production, but that there is also a delayed, second order regulation of this process via extrahepatic effects. We further provide our views regarding the timing, dominance, and physiological relevance of these effects and discuss novel concepts regarding insulin regulation of adipose tissue fatty acid metabolism and central nervous system (CNS) signaling to the liver, as regulators of insulin's extrahepatic effects on glucose production.

Abstract
Introduction Primary hyperparathyroidism (PHPT), usually caused by a parathyroid adenoma, is characterized by a pathologically high secretion of parathyroid hormone and consequent hypercalcemia. PHPT has a high prevalence among elderly patients and might be responsible for neuropsychiatric symptoms. Objectives We aim to report the rare manifestation of acute psychosis accompanying a PHPT diagnosis, and to discuss the neurobiological relationship between hyperparathyroidism, hypercalcaemia and neuropsychiatric symptoms. Methods We present a clinical case based on patient’s history and clinical data, along with a literature review on PHPT neuropsychiatric symptons. Results We present the case of a 68-year-old man diagnosed with PHPT in November 2019. He was brought up to psychiatric evaluation for the first time in May 2020 upon behavioral changes (aggressiveness and bizarre rituals). The patient described the sensation of burns scattered throughout the body since January 2020, felling anxious and frightened, sleeping poorly and progressive social isolation. He presented delusional ideas of mystical and paranoid content. No significant cognitive impairments were found. The patient’s psychosis was partially responsive to atypical antipsychotics. He’s waiting for surgery. Hypercalcaemia might manifest as mood disorders, cognitive changes and rarely as acute psychosis. Although there is not yet a clear mechanism to explain it, high calcium levels seem to cause neurotoxicity and neurotransmission dysfunction. Restoration of normal calcium levels tend to resolve neuropsychiatric symptoms, but in PHPT parathyroidectomy is usually recommended. Conclusions Neuropsychiatric symptoms are responsible for great disability, and demand an organic in-depth investigation. A multidisciplinary team approach must always be considered in the management of such conditions.

Abstract
IntroductionAnimal hoarding is characterized by hoarding of a large number of animals without providing minimum conditions of nutrition and sanitation, accompanied by lack of insight for the behavior and by social isolation. Despite studies detecting an increasing incidence, the behavior is still poorly understood.ObjectivesTo review clinical evidence on animal hoarding and to report a clinical case.MethodsWe report a clinical case based on patient’s history and clinical data, along with a review of the literature on animal hoarding. The terms “Noah syndrome” and “animal hoarding disorder” were searched on PubMed® database.ResultsWe present the case of a 51-years-old woman, living alone, with higher education. His first contact with psychiatry was in August 2019 upon aggravated self-neglect and behavioral disorganization. She was living with around 40 cats, her home was extremely deteriorated. In December 2019 she was admitted to a psychiatric unit. A schizophrenia diagnosis was established and pharmacological treatment was initiated. She was discharged to a chronic psychiatric institution. Studies found out that animal hoarders are typically middle age/older women living alone in squalid conditions. Animal hoarding is characterized by a chronic course and intense emotional attachment to animals. It seems to be associated with traumatic situations, as well as mental disorders such as schizophrenia or dementia. Published data on intervention and treatment is still limited.ConclusionsAnimal hoarding phenomenon requires further investigation, regarding developmental risk factors and co-morbid mental disorders. Comprehensive approaches to clinical intervention and management strategies in animal hoarding are necessary.

Abstract
Introduction The psychiatric care paradigm has shifted towards community-centered models. Yet, prolonged hospitalizations are still a reality, with debated impact at healthcare systems and patients. Objectives This work aims to describe prolonged hospitalizations in acute psychiatric wards through patients’ sociodemographic and clinical data. Methods We analyzed a national hospitalization database that contained all hospitalization episodes registered in Portuguese public hospitals from 2008 to 2015. All episodes with a primary diagnosis of mental disorder defined as ICD-9-CM codes 290.x-319.x were included. Prolonged hospitalizations were defined as having a LoS ≥ P97.5; LOS ≥180 days or LOS ≥1 year. Age, sex, lengh of stay, in-hospital mortality were analysed. Results The LoS ≥ P97.5(≥62 days) group comprised 3911 hospitalizations (2.3% of all psychiatric hospitalizations) and 1755 patients. The median LOS was 81 days and the mean age was 51 years. Sex was equally distributed, though a higher frequency of male patients was found on the ≥180 days (n=364) and ≥ 1 year (n=121) groups. Psychotic disorders were the main diagnosis at discharge (n= 1769, 45.2%), followed by mood disorders (n=1057, 27.0%) and dementia (n=451, 11.5%). In-hospital mortality increased in the higher LoS groups (1.1%; 4.4%; 9.1%, respectively). Conclusions Overall, middle aged patients with psychotic disorders represent most of the prolonged hospitalizations occurring in acute psychiatric wards. Community-based programs require further development to meet the existing needs. Disclosure No significant relationships.

Abstract
Glycosyl cations are key intermediates in the glycosylation reactions taking place through a SN1-type mechanism. To obtain a reliable description of the glycosylation reaction mechanism a combination of computational studies and experimental data such as kinetic isotopic effects is needed. Computational studies have elucidated SN2-type glycosylation reaction mechanisms, but elucidation of mechanisms in which ion pairs can be formed presents some difficulties because of the recombination of the ions. Recent topological and dynamic studies open the door to the ultimate confirmation of the presence of glycosyl cations in the form of intimate ion pairs during certain glycosylation reactions. This review covers the state-of-the-art tools and applications of computational chemistry mainly developed during the last ten years to understand glycosylation reactions in which an oxocarbenium ion could be involved.
