Abstract
INTRODUCTION Ankle-Brachial Index (ABI) is a well-established diagnostic tool for evaluating peripheral arterial disease (PAD). Limitations in its application led to the development of alternative diagnostic methods, including Toe-Brachial Index (TBI) and Transcutaneous Pressure of Oxygen (TcPO2), yet these are not as widely available as ABI. Recently, Pedal Acceleration Time (PAT), has gained popularity as a new tool to assess PAD, requiring only an ultrasound. This study seeks to further establish the correlation between ABI and PAT, determining whether PAT can be a reliable alternative for diagnosing and assessing the severity of PAD. METHODS ABI and PAT were measured in patients attending our consult with no history of vascular or endovascular surgery. Limbs with unmeasurable ABI were excluded. Patients were categorized into groups based on their PAD stage according to the Fontaine classification. Patient demographics, comorbidities and respective ABI and PAT were analysed. RESULTS Sixty-nine patients (114 limbs) were included in the study. Mean age 68 ± 11.7 years, 78.3% male and 33.3% diabetic patients. Fifty-three claudicant limbs (46.5%) and 26 limbs (22.8%) with chronic limb threatening ischemia. Pearson correlation coefficient between ABI and PAT, showed a strong negative correlation (r= -0.78; p<0.01). Mean ABI and PAT for limbs in Fontaine stage I were 0.94 ± 0.17 and 82.0 ± 27.4 ms; Fontaine stage IIa 0.69 ± 0.21 and 141.3 ± 57.8 ms; Fontaine stage IIb 0.54 ± 0.14 and 173.4 ± 65.1 ms; Fontaine stage III 0.43 ± 0.15 and 216 ± 33.2 ms; Fontaine stage IV 0.49 ± 0.17 and 206.7 ± 78.1 ms, respectively. CONCLUSION Our study suggests an inverse correlation between ABI and PAT, in accordance with the findings published in the literature, thus supporting the use of PAT as an easily reproducible and efficient alternative to ABI for evaluating the severity of PAD.

Abstract
INTRODUCTION Thoracic aortic aneurysms (TAAs) are an increasingly prevalent pathology with significant associated morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) is the primary line of treatment. The purpose of this study was to analyse a single center's experience in the treatment of TAAs and identify possible risk factors for worse outcomes. METHODS A retrospective review of our institutional database was done to identify all patients treated for TAAs in a 10-year period, from 1 January 2012 to 31 December 2022. Data were extracted from patients' medical records. Primary outcome was all-cause mortality and secondary outcomes were procedure related morbidity (vascular access complications, medullary ischaemia, stroke, endoleaks, migration, aneurysm sac enlargement >5 mm) and need for reintervention at 1-, 6- and 12-month follow-up. A descriptive and inferential analysis of the data was performed. Statistical analyses were conducted using the IBM Statistical Package for Social Sciences (SPSS) software. RESULTS We identified 34 patients treated for TAAs in this period. Mean age was 68 years [47-87] and 79.4% of patients were male. Mean aneurysm diameter was 63 mm [35-100], 55.9% fusiform and 44.1% saccular. The majority (91.2%) were located at the descending thoracic aorta and 3 (8.8%) of them extended to the aortic arch. The most common aetiology was degenerative in 22 patients (64.7%), followed by aortic dissection in 8 patients (23.5%). Elective surgery was performed in 19 (61.3%) patients and 12 (38.7%) had urgent repair. TEVAR was the treatment of choice in 24 (77.4%) patients, and the remaining 7 (22.6%) were treated with hybrid surgery. Mean length of hospital stay was 10 days [2-80] (6 days for elective repair versus 16 days for urgent repair, p = .016). Follow-up period ranged from 1 month to 10 years. At 1 year follow-up, all-cause mortality was 15%, morbidity was 30% (with 6 (22%) patients having a type Ia endoleak) and need for reintervention was 22%. Aneurysm diameter was a significant risk factor for procedure related morbidity (median diameter of 73.5 mm versus 56.0 mm in patients with no morbidity; p = .027). The presence of type Ia endoleak was significantly associated with higher reintervention rates (p = .001), but not with higher mortality rates (p = .515). Age, female sex, aetiology and urgent repair weren't associated with any significant differences in the outcomes. CONCLUSIONS TEVAR proved to be effective in the treatment of TAAs, with good outcomes at short and mid-term follow-up. TAAs should be diagnosed earlier and be promptly treated when meeting criteria to prevent worse outcomes.

Abstract
Introduction Popliteal artery aneurysms (PAAs) pose some challenges in their surgical management and are often treated by exclusion and bypass procedures. However, post-operative complications, such as endoleaks and sac growth, can occur, potentially leading to serious consequences. Endoleaks, characterised by persistent flow within the aneurysm sac after repair, can cause sac expansion, increasing the risk of adverse outcomes, including the formation of cutaneous fistulae, a rare but potentially severe complication. Report A 75 year old male with a history of previous bilateral PAA exclusion with a left femoropopliteal bypass using reversed great saphenous vein (GSV) graft in 2012 and a right femoropopliteal bypass using a PTFE prosthesis in 2017, both through medial approach, presented with pain and ulceration in the left popliteal region. Previous angiography had shown residual arterial flow through collateral vessels, requiring thrombin injection. Bilateral bypass thrombosis had also occurred after discontinuing anticoagulation. Computed tomography angiography confirmed a complicated excluded left popliteal aneurysm with superinfection. The patient underwent elective surgery, involving partial aneurysmectomy, endoaneurysmorrhaphy, and fistulectomy through a posterior approach. Post-operatively, the patient experienced resolution of symptoms and inflammatory signs. Discussion The optimal approach for treating PAAs remains a subject of debate, with some experts advocating the posterior approach to prevent sac growth. However, others support the medial approach, reporting satisfactory results. In this case, the medial approach resulted in incomplete exclusion, leading to sac expansion and a cutaneous fistula. Timely re-intervention through the posterior approach successfully resolved the complication. This report highlights a rare but serious complication of incomplete PAA exclusion. Vigilant post-operative surveillance and intervention are crucial to manage such cases effectively. Further research is warranted to determine the optimal approach for PAA repair and prevent associated complications.

Abstract
BACKGROUND Coral reef aorta (CRA) is defined by the presence of heavily calcified exophytic plaques that protrude into the aortic lumen. However, the exact causes and development of this condition are still not fully understood. When the aortic branches are affected, it can result in various symptoms. Despite ongoing research, there is currently no established consensus on the best treatment for CRA. This review aims to examine the latest findings regarding the clinical presentation and approach to treating patients with CRA. METHODS We conducted a systematic electronic search of the literature using the PubMed and Embase databases. Throughout the search, we adhered to the guidelines outlined in the PRISMA framework. From the identified publications, we extracted information pertaining to patients' characteristics, symptoms, and types of treatment from a total of 124 cases reported over the past 20 years. The primary focus of our analysis was to assess the improvement of signs and symptoms, as well as to evaluate any postoperative complications. To achieve this, we performed both descriptive and inferential analyses on the collected data. Additionally, we conducted subgroup analyses based on treatment types and symptoms observed at presentation, presenting the findings in the form of odds ratios (ORs). RESULTS After removing duplicate articles, we carefully screened the titles of 67 retrieved articles and excluded those that did not align with the purpose of our study. Subsequently, we thoroughly analyzed the remaining 41 articles along with their references, ultimately including 29 studies that were deemed most relevant for our systematic review. We examined a total of 124 cases of patients diagnosed with CRA, comprising 77 (62.1%) females and 48 (38.7%) males, with a mean age of 59 years (range: 37-84). The predominant signs and symptoms observed were intermittent claudication, reported in 57 (46.0%) patients, followed by refractory hypertension in 45 (36.3%) patients, intestinal angina in 28 (22.6%) patients, and renal insufficiency in 15 (12.1%) patients. Among the treated patients, 110 (88.7%) underwent open surgery repair (OSR), 11 (8.9%) received endovascular treatment, and 3 (2.4%) underwent laparoscopy. Postoperatively, a significant number of patients experienced substantial relief or complete resolution of their symptoms, as well as improved control of hypertension and renal function. In the group of patients treated with OSR, the inhospital stay mortality rate was 10.9%, the morbidity rate was 28.2%, and the reintervention rate was 15.5%. The high mortality rate during hospital stays in this group may be associated with such invasive procedures performed on patients who have substantial cardiovascular burden and multiple comorbidities. Conversely, no postoperative complications were reported in the group of patients treated with endovascular procedures or laparoscopic surgery. CONCLUSIONS While coral reef aorta (CRA) is considered a rare condition, it is crucial for the medical community to remain vigilant about its diagnosis, particularly in patients presenting with symptoms such as intermittent claudication, refractory hypertension, renal impairment, or intestinal angina. Based on the findings of this review, both OSR and endovascular treatment have shown promise as viable therapeutic options. Although endovascular therapies may not always be feasible or may have reduced durability in these calcified bulky lesions, they should be considered in patients with multiple comorbidities, due to the high postoperative mortality rates associated with more invasive approaches. Additionally, these endoluminal procedures have demonstrated good patency rates during the 18-month follow-up period. It is essential to emphasize that the treatment strategy should be determined on a case-by-case basis, involving a multidisciplinary team to tailor it to the specific needs of each individual patient.

Abstract
Persistent sciatic artery is a rare anatomic variation due to the lack of regression during fetal development, associated sometimes with abnormalities of the iliofemoral arterial axis and predisposing the patients to aneurysm formation and thromboembolism, which can compromise the limb. In our department, we assisted a 59-year-old male with an acute limb ischemia as result of an incidental finding of a thrombosed persistent sciatic artery aneurysm.

Abstract
BACKGROUND Approximately 1.4 million strokes/year causing about 1.1 million deaths annually occur in Europe and 10%-15% of those strokes are result of thromboembolism from a previously significant asymptomatic carotid stenosis (ACS). Medical treatment has improved considerably in the last 15 years; however, its success depends on patient compliance. The aim of our study was to evaluate, in patients with ACS, the implementation and patient adherence to best medical treatment (BMT). Additionally, we sought to determine the "real-world" incidence of cerebrovascular/coronary events in a cohort of nonoperated ACS patients and weighing this risk against surgical complications in patients with ACS undergoing surgical treatment at our Department. METHODS Patients with ACS ≥ 60% identified by a carotid ultrasound performed at our Department were retrospectively evaluated. Patients selected to BMT were excluded if the follow-up period was inferior to 2 years, as well as patients lost in follow-up, with missing clinical information and submitted to carotid stenting. Patients' data collection was supported by hospital reporting system and data were introduced into a database created for the purpose. Statistical analysis was performed using SPSS-25 software. RESULTS After exclusion criteria were applied, the last 120 consecutive patients (60 with ACS submitted do carotid endarterectomy and 60 with ACS under BMT) were retrospectively evaluated. Twenty one patients had ipsilateral events for more than 6 months. Most patients had hypertension (n = 107; 89%), dyslipidemia (n = 101; 84%), 40% had diabetes, 33% diagnosed coronary disease, 32% were overweight or obese, and 17% were current smokers. Blood pressure control, normal weight, statin with/without ezetimibe association, and antiaggregant therapy were only achieved in 33 patients and only 5 had additionally low-density lipoprotein levels < 70 mg/dL, hemoglobin A1c < 7%, and were nonsmokers. Of the 60 patients assigned to medical treatment, 3 (5%) had a stroke at 2 years of follow-up, which was fatal in 1 patient. Among patients submitted to carotid endarterectomy, perioperative stroke was documented in 3% of the patients, none of them disabling or fatal. CONCLUSIONS Although some recent studies report a risk of ipsilateral stroke of only 0.34% per year in patients with ACS ≥ 50% under BMT therapy in our everyday practice strict compliance to medical treatment fails in most patients. In consequence, we think that a "one-size-fits-all" guideline policy may not be appropriate for all patients and the management of specific ACS patients may need to be individualized.

Abstract
PURPOSE To compare 0.01% atropine with DIMS spectacle lenses in the prevention of myopia progression in European children. METHODS This was a retrospective study including data from pediatric European patients with myopia. From November 2021 to March 2022, only 0.01% atropine was prescribed because DIMS lenses were still not available in Portugal. From March to October 2022, only DIMS spectacle lenses were prescribed due to patients' parents' preference. Myopia progression endpoints were axial length (AL) and spherical equivalent (SE) differences between before and 6 months after treatment. AL and SE evolution were compared using a general linear model with repeated measures. RESULTS The study included 98 eyes from 50 patients: 47 in the atropine group and 51 in the DIMS group. There were no statistically significant differences between groups in terms of initial AL, initial SE, sex or age. The mean AL elongation at 6 months was 0.057 mm in the atropine group (SD = 0.118) and 0.002 mm (SD = 0.077) in the DIMS group. SE progression was - 0.098 (SD = 0.232) D in the atropine group and - 0.039 (SD = 0.105) D in the DIMS group. AL elongation was significantly lower in the DIMS lens group (p = 0.038, partial Eta2 = 0.045). There was no difference in SE progression between groups (p = 0.302, partial Eta2 = 0.011). CONCLUSION Comparison between 0.01% atropine eyedrops and DIMS spectacle lenses for slowing the progression of myopia favored DIMS lenses in terms of AL elongation in a short-term follow-up. There was no difference in terms of SE between groups.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) persistence among men who have sex with men (MSM) in real world clinical settings for HIV prevention is suboptimal. New longer-acting formulations of PrEP are becoming available, including injectables, subdermal implants, and other oral medications. These longer-acting formulations have the potential to improve retention among those who have challenges remaining adherent to daily oral PrEP. METHODS We interviewed 49 MSM who had initiated but discontinued oral PrEP at three diverse clinics across the United States. We examined participants' perspectives about long-acting PrEP formulations and how long-acting options could affect PrEP use using thematic analysis. RESULTS Participants were not very knowledgeable about long-acting formulations of PrEP but were open to learning about them and considering use. Participants were concerned about safety and efficacy of products given that they were still newer and/or in development. Finally, participants had clear preferences for oral pills, injectables, and then subdermal implants and were most interested in options that reduced the number of visits to the clinic. CONCLUSION Long-acting formulations of PrEP are acceptable to MSM with suboptimal PrEP persistence and have the potential to improve PrEP persistence. However, many felt they needed more information on safety, efficacy, and use to consider these options. As these long-acting formulations are implemented, public health campaigns and clinical interventions to encourage may maximize uptake particularly among those who are not currently adherent to daily oral PrEP.

Abstract
INTRODUCTION Silicone tube implantation in lymphoedema reduces symptoms by improving fluid drainage. Although there are descriptions of implant host reaction that can be misdiagnosed as graft infections these are scarce. REPORT A 34 year old female with lymphoedema of the lower limb, underwent silicone tube implantation. Ten months after surgery, the patient presented with fever and dermatolymphangioadenitis of the limb. Ultrasound suggested an abscess surrounding the tubes. Clinical improvement was achieved after a 6-day cycle of meropenem. She was discharged under oral cefuroxime and clindamycin for one week. After 1 month, CT-angiography was performed showing only residual inflammation surrounding the tubes, the patient was asymptomatic and limb diameter was normal. CONCLUSION Sudden onset and improvement of the patient's condition after a short cycle of antibiotics without the need of tube removal supports a host-like reaction rather than an actual infection. Doctors should be aware of such complications avoiding unnecessary procedures.

Abstract
Summary Background. Drug hypersensitivity reactions are presumably immune-mediated reactions that cause reproducible signs and/or symptoms. Overdiagnosis of drug allergy, frequently self-reported, is common and carries significant limitations. We intended to analyze the frequency and impact of drug allergy in hospitalized patients. Methods. A retrospective study was conducted in an Internal Medicine ward at a tertiary hospital in Portugal. All patients with a drug allergy report admitted within a 3-year period were included. Data were collected from their electronic medical records. Results. We found that 15.4% of patients had a report of drug allergy, with antibiotics being the most common (56.4%), followed by non-steroidal anti-inflammatory drugs (21.7%) and radiocontrast media (7.0%). The allergy report affected the clinical approach of 14.5% of patients by motivating the use of second-line agents, or the eviction of necessary procedures. The usage of alternative antibiotics entailed a cost increase of 2.4 times. There were 14.7% of patients to whom the suspected drug was administered: 87.0% tolerated and 13.0% developed a reaction. Only 1.9% were referred to our Allergy and Clinical Immunology department and proceeded in their allergy study. Conclusions. In this study, a considerable number of patients had a drug allergy label on their records. This label contributed to an increase in the cost of treatment, or the avoidance of necessary exams. However, disregarding an allergy record may lead to potentially life-threatening reactions that proper risk assessment could avoid. Further investigation should always be part of the follow-up routine of these patients, and better articulation between departments should be encouraged.

Abstract
OBJECTIVES The emergency department (ED) is a very important healthcare entrance point, known for its challenging organisation and management due to demand unpredictability. An accurate forecast system of ED visits is crucial to the implementation of better management strategies that optimise resources utilization, reduce costs and improve public confidence. The aim of this review is to investigate the different factors that affect the ED visits forecasting outcomes, in particular the predictive variables and type of models applied. METHODS A systematic search was conducted in PubMed, Web of Science and Scopus. The review methodology followed the PRISMA statement guidelines. RESULTS Seven studies were selected, all exploring predictive models to forecast ED daily visits for general care. MAPE and RMAE were used to measure models' accuracy. All models displayed good accuracy, with errors below 10%. CONCLUSIONS Model selection and accuracy was found to be particularly sensitive to the ED dimension. While ARIMA-based and other linear models have good performance for short-time forecast, some machine learning methods proved to be more stable when forecasting multiple horizons. The inclusion of exogenous variables was found to be advantageous only in bigger EDs.

Abstract
Effective antimicrobial treatment has been identified as a serious and unmet medical need. Herein, we present a strategy based on deep eutectic systems (DES) to overcome current limitations, answering the need not only to effectively kill bacterial agents but also to avoid their adhesion and proliferation, which is associated with biofilm formation and have a crucial impact on bacterial virulence. To achieve such a goal, natural deep eutectic systems (NADES) based on menthol (Me) and saturated free fatty acids (FFA) were produced, fully physicochemical characterized, and its bioactive properties were described. The antimicrobial potential of menthol-based NADES with FFA, namely, myristic acid (MA), lauric acid (LA), and stearic acid (SA) were investigated towards a broad panel of microorganisms. The obtained data indicates that NADES possess effective antimicrobial properties towards the Gram-positive bacterial and fungal strains tested. Among the tested formulations, Me:LA at a molar ratio of 4:1 molar was used to carry out a biofilm detachment/removal assay due to is superior microbiological properties. This formulation was able to effectively lead to biofilm removal/dispersion of not only methicillin-resistant Staphylococcus aureus (MRSA) and Candida albicans, but also Escherichia coli, without the need of any additional physical force or antibiotic. Furthermore, since microbial invasion and biofilm formation is highly undesired in wound healing, namely in chronic wound healing, the wound healing properties of these eutectic formulations was also investigated. The results suggest that these NADES can cope with microbial invasion and biofilm detachment while not compromising normal keratinocyte proliferation and migration verified in wound healing and epidermis repair, while also contributing to the reduction of cell stress and inflammation via the control of ROS production. In conclusion, these results provide the indication that NADES based on Me and FFA holds great interest as antimicrobial agents for preventive and therapeutic applications in various clinical settings, including wound healing.

Abstract
Introduction Endoleaks are a common complication following endovascular aneurysm repair, yet type IIIb are rare, especially with newer devices, and associated with high morbidity due to repressurisation of the sac. As endografts are used in patients with longer life expectancy, late type IIIb endoleaks are to be expected. This is a report of a giant common iliac aneurysm resulting from a misdiagnosed type IIIb endoleak. Report An 85 year old man with history of right common iliac artery aneurysm, treated in 2003 with an EXCLUDER AAA Endoprosthesis (WL Gore, Flagstaff, AZ, USA) with iliac limb extension into the external iliac artery, presented at the emergency department with abdominal pain, hypotension, and syncope. He had a known endoleak, unsuccessfully treated by relining the right iliac stent graft overlap zones for a suspected type IIIa endoleak (2009), coil embolisation, and computed tomography (CT) guided thrombin injection of the aneurysmatic sac for a type II (2010), none of which managed to treat the cause with continuous aneurysm growth. The patient refused further treatments, but agreed to maintain surveillance. At admission, CT angiography showed common iliac aneurysm (185 × 134 mm) sac rupture without a visible endoleak. Resuscitative endovascular balloon occlusion of the aorta (REBOA) technique was performed to obtain haemodynamic control, then the aneurysm was approached through a midline incision. A type IIIb endoleak was identified due to a fabric tear on the right iliac limb extension. Suture was attempted without success, then relining of the lesion with an Endurant II Limb (Medtronic, Minneapolis, MN, USA) was performed, which managed to repair the endoleak. Discussion Type IIIb endoleaks are uncommon and underdiagnosed due to fabric defects being too small or leaking intermittently. They can mimic other types of endoleaks and may cause aneurysm growth and rupture. One should consider this type of endoleak if previous treatments for other types were unsuccessful.

Abstract
Abstract
Background
Cardiac channelopathies are a group of inherited cardiovascular diseases with increased risk of sudden cardiac death in structurally normal hearts. The psychological status after their diagnosis has not been thoroughly studied.
Purpose
To establish health-related quality of life (QOL) and emotional response to the diagnosis of channelopathies in a cohort of patients and their families.
Methods
Adult patients with diagnosis of channelopathies and their relatives were eligible. After enrolment they were divided in 3 groups, according to the time of psychological evaluation: At diagnosis (T0), one year (T1), and 2 years after diagnosis (T2). Psychological evaluation was conducted through self-report questionnaires on QOL (SF-12), general anxiety (BAI), depression (BDI-II), perceived stress (PSS-10), post-traumatic stress (IES-R), and protective resilience resources (RSA).
Results
From August 2020 to April 2021, 64 patients (95% Brugada syndrome, 3% long QT syndrome, and 2% catecholaminergic polymorphic ventricular tachycardia) and 41 relatives were enrolled. A control group of 105 healthy subjects, matched to the study group regarding age, gender and level of education, was also enrolled.
Patients at T0 showed increased physical and reduced mental QOL; at T1, reduction of RSA; and at T2, reduction of RSA and increased BAI. A significant percentage of patients referred the occurrence of a traumatic event during their lifetime at T0, T1 and T2 (Figure 1). At T0 relatives presented high PSS-10 and a high proportion of them reported experiencing a traumatic episode during their lifetime. BAI score was high among relatives at T0, T1 and T2, reaching levels of concern 2 years after the diagnosis (Figure 2). Female gender independently predicted MCS-12 in patients at T0.
Conclusions
Diagnosis of channelopathies impact different areas of QOL and the psychological sphere in patients (QOL, resilience, anxiety and occurrence of traumatic events during lifetime) and relatives (anxiety, stress, and occurrence of traumatic events during lifetime), and at different moments after the diagnosis. Female gender was an independent predictor of worse mental QOL in patients at T0. Patients and their families should be involved in psychological counselling and psychoeducational interventions, taking into account their differences and the timing of psychological responses, in order to better support them in adjusting to their new life circumstances.

Abstract
Intellectual developmental disorder with dysmorphic facies and behavioral abnormalities (IDDFBA) is a recently described autosomal dominant entity caused by pathogenic variants, mostly de novo, in the FBXO11 gene. It presents in the first years of life with highly variable clinical manifestations. The main features of IDDFBA include borderline-to-severe intellectual disability, behavioral problems, hypotonia, facial dysmorphisms, minor skeletal abnormalities, and recurrent infections. Although eye problems, such as refractive errors, eye misalignment and minor visual changes, have been described in about 48% of patients, a major ocular defect, namely, bilateral optic nerve hypoplasia, has been reported in the literature only once. We report an 8-year-old boy with a novel de novo pathogenic variant in FBXO11 gene (NM_001190274.1: c.1166dup, p.Cys390Metfs∗3) and a complex ophthalmological phenotype, consisting of right microphthalmia, very shallow anterior chamber, and persistent pupillary membrane, right dense nuclear cataract, bilateral optic nerve hypoplasia, and bilateral horizontal manifest nystagmus.

Abstract
Abstract
Background
Neurofibromatosis type 1 (NF1) is the most common tumor predisposition syndrome, with an incidence of 1/3500. Plexiform neurofibromas (PN) are benign tumors that can occur along the nerve sheath throughout the body, with unpredictable growth and with risk of malignant transformation. Symptoms will depend on their size and location, and include pain, deformity and functional impairment. There is a great variability in the PN severity and impact on quality-of-life (QOL). An unknown percentage of NF1 patients may need treatment, either medical and/or surgical.
Objectives
To assess the frequency of PN in a NF1 population followed in a comprehensive cancer center.
Material and Methods
Retrospective study. All patients with NF1 and PN followed in our center, between 31/12/2000 and 31/12/2021.
Results
Of 438 NF1 patients, 185 had PN (42%). 52 NF1 patients with PN were children (≤ 18). The most common symptoms were pain in 71 people (38,4%), deformity in 70 (37,8%) and functional impairment in 69 (37,3%). Several patients had a combination of these symptoms. Different treatment modalities were used for PN: medical, surgical or both. In this study, 54 patients (29,1%) were treated with MEK inhibitors (selumetinib), 74 patients (40%) were treated surgically and 12,4% (23) needed a combined approach (medical and surgical treatment).
Conclusion
PN are frequent in NF1 patients. A significant percentage is symptomatic and will require treatment, surgical, medical or both. There is no standard of care for PN NF1. The timing and sequence of medical and surgical treatment is yet to be defined.

HFpEF is the most common form of heart disease in the elderly and is associated with high morbidity and mortality. Our understanding of HFpEF pathophysiology is limited and development of efficient therapies that alter the clinical course of the disease has proved greatly challenging. Although aging is a risk factor of HFpEF1, the involvement of aging hallmarks such as cell senescent and immunosenescence is unclear. Recently, a link between endothelial senescence and HFpEF development was demonstrated in mice with accelerated aging [1], endorsing anti-aging pharmacologic as potential new therapeutic alternatives for HFpEF. In fact, the senolytic (drugs that selectively promote apoptosis of senescent cells) ABT-263 has already proven efficacy in the context of cardiovascular diseases. Further studies are needed to clarify the relevance of aging and of anti-aging therapies in the context of HFpEF.
Using ZSF1 obese rats (ZSF1-Ob) as model of HFpEF we showed from 18 weeks signs of immunosenescence compared to ZSF1-Ln, namely an increased frequency of circulating myeloid cells and decreased frequency of T and B cells. Concomitantly, expression of pro-inflammatory factors (IL-6, IL-1, TGF-β, TNF-α) was upregulated in peripheral blood mononuclear cells (PBMCs) of ZSF1-Ob which also displayed characteristic features of cell senescence (p21 expression, lysosomal endogenous Beta-galactosidase (SA-B-Gal) senescence-associated secretory phenotype (SASP) and up-regulation of BCL-XL. Importantly, no signs of cellular senescence (SA-B-gal, pH2AX and senescence associated pathways) were found in the main hematopoietic organs (spleen and bone marrow). Alongside, these systemic alterations, an upsurge of cellular senescence was observed in myocardium of ZSF1-Ob rats, particularly in endothelial and hematopoietic cells. Serum of ZSF1-Ob rat was able to induce activation and cellular senescence of cardiac microvascular endothelial cells, indicating that systemic circulating factors may be the upstream mechanism of cellular senescence and dysfunction in HFpEF. Analysis of HFpEF patients and a control cohort adjusted to main co-morbidities further demonstrated accumulation of senescent monocytes in HFpEF patients. In these patients, the senescence marker SA-B-Gal correlated with plasmatic brain natriuretic peptide (BNP) levels and pulmonary artery systolic pressure. Targeting aging hallmarks through the treatment of ZSF1-Ob rat with ABT-263 resulted in a reduction in circulating senescent cells, decreased systemic and local inflammation, re-established immune proportions, restore the levels of circulating BNP and attenuated myocardial remodeling, particularly endothelial dysfunction and fibrosis.
Collectively these findings support that premature cellular senescence contributes to the establishment of a deleterious pro-inflammatory environment in HFpEF and that senolytic agents hold promise for the treatment of this syndrome.

Abstract
Curcumin (Cur), a polyphenolic compound derived from Curcuma longa L., has garnered the attention of the scientific community due to its remarkable biological properties such as its potential as a photosensitizing agent for photodynamic therapy (PDT). However, due to its low solubility in aqueous media and instability at physiological and alkaline pH, Cur has struggled to find relevant clinical application. To tackle these shortcomings, two distinct Cur-based formulations based on either complexation with methyl-β-cyclodextrin (MβCD), MβCDC-Cur, or dissolution in a choline chloride (ChCl): glycerol (Gly) deep eutectic solvent (DES), DES-Cur, were produced, physio-chemically characterized and compared regarding their potential as phototherapeutic agents for blue-light antimicrobial photodynamic therapy (aPDT) approaches. Both MβCD-Cur and DES-Cur were able to greatly enhance Cur solubility profile when compared to Cur powder. However, MβCD-Cur appears to hinder some of Cur's basal biological properties and possessed greater basal cytotoxicity towards L929 murine fibroblast cell line. Furthermore, MβCD-Cur was less photo-responsive when exposed to light which may hamper its application in blue-light aPDT approaches. In contrast, DES-Cur showed good biological properties and high photoresponsivity, displaying relevant phototoxicity against bacterial pathogens (≥ 99.9% bacterial reduction) while being better tolerated by L929 murine cells. Overall, this study found DES to be the more effective vehicle for Cur in terms of phototherapeutic potential which will serve as basis to develop novel platforms and approaches for blue-light aPDT targeting localized superficial infections.

Abstract
OBJECTIVES Chronic post-thrombotic syndrome (PTS) may develop in up to 50% of patients after deep vein thrombosis (DVT) and may reduce patients' quality of life (QoL). We aimed to evaluate the association of PTS severity with QoL in patients with proximal DVT submitted to medical treatment and also to identify modifiable and non-modifiable risk factors related to PTS. METHODS Patients with iliac or femoropopliteal DVT observed in Vascular Surgery consultation in our institution from 1 year period with unilateral DVT were selected. Patients with total vein recanalization were excluded. Villalta scale was applied to assess PTS degree and VEINES-QoL/Sym questionnaire was used as a disease-specific QoL measure. Correlation between PTS degree and VEINES-QoL/Sym score and predictors of PTS were determined. RESULTS 56 patients accepted to enter the study. From those, 66.1% were female, 64.3% (n=36) had iliac and 35.7% (n=20) femoropopliteal DVT. PTS was present in 52.8% of iliac and 65.0% of femoropopliteal DVT patients observed in consultation (P=0.413). There was a significant correlation with PTS degree and both VEINES-QoL and VEINES-Sym scores (P<0.001). Major depression (OR=5.63, P=0.045) and regular wear of compressing stockings (OR=4.69, P=0.041) were the only independent factors associated with PTS. Patients with depression had lower QoL scores, while patients with PTS who wear compression stockings had similar QoL scores compared to patients without PTS. Ultrasound alterations (OR=3.28, P=0.174), age, gender, iliac DVT, multiple DVT and time after DVT (P>0.2) were not associated with PTS syndrome. CONCLUSIONS VEINES-QoL/Sym had moderate inverse correlation with PTS degree. Depression was associated with both PTS and lower QoL scores. Patients with PTS criteria compliant to wearing compressing stockings had similar QoL scores to patients without PTS.

Abstract
Malignant tumors of the penis are rare, most of them being squamous cell carcinomas (SCCs). We report the case of a 75-year-old man with a large penile mass submitted to partial penectomy. The specimen showed an exophytic mass involving the glans, coronal sulcus, and prepuce. Microscopic examination showed a carcinoma with two distinct areas: a mixed SCC and a sarcomatoid carcinoma. The SCC component had areas of verrucous carcinoma and areas of classical invasive SCC. The tumor cells expressed p63 with the absence of p16 expression. Vimentin and p53 were positive in the sarcomatous component. The morphology and immunohistochemistry were compatible with mixed SCC (verrucous hybrid-sarcomatoid carcinoma). Additionally, the tumor cells also expressed 3 different clones of PDL1 (22C3, SP263, and SP142). Two months later, the patient presented local recurrence with multiple lymph nodes and lung metastases, dying 7 weeks later. Mixed tumors represent diagnostic challenges. The correct identification of adverse prognostic factors can be the first step to implement the treatment with a higher probability of success.

Abstract
In studies of human IVF, as compared to frozen embryo transfer (ET), fresh ET is associated with smaller infants and higher risk of small for gestational age infants. Recent observations suggest that ET using vitrified embryos is associated with higher pregnancy and live birth rates compared to fresh ET, but increased rates of large for gestational age infants. The mechanisms underlying these associations are largely unknown, and available evidence suggests that the influence of IVF, vitrification and the superovulated (SO) uterine environment on placental function and fetal growth is complex. This warrants further investigation given the prevalent practice in human IVF of both fresh ET into a SO uterine environment, and vitrification with ET into a more physiologic uterine environment. Using a mouse model that closely resembles human IVF, we investigated if vitrification of IVF embryos better preserves placental function and results in better pregnancy outcomes as compared to fresh ET because of transfer into a more physiologic endometrium. We found that the SO environment, independent of vitrification status, reduced implantation rates, inhibited placental mechanistic target of rapamycin signaling and induced placental stress signaling, resulting in fetal growth restriction (1.080 ± 0.05 g estrous fresh (n = 17 litters), 1.176 ± 0.05 g estrous vitrified (n = 12), 0.771 ± 0.06 g SO fresh (n = 15), 0.895 ± 0.08 g SO vitrified (n = 10), P < 0.0001). In addition, our study suggests that vitrification impairs the developmental potential of IVF blastocysts that resulted in a significantly smaller litter size (2.6 ± 2.3 fresh estrous vs 2.5 ± 2.4 fresh SO vs 1.6 ± 1.7 estrous vitrified vs 1.7 ± 1.8 SO vitrified, P = 0.019), with no effect on fetal growth or placental function at term. Our findings suggest that vitrification may negatively impact early embryonic viability, while the SO maternal uterine environment impairs both placental development and fetal growth in IVF.

Abstract
INTRODUCTION Coronavirus disease 2019 (COVID-19) impacted emergency services worldwide. AIM We aimed to evaluate COVID-19 effect on the number of stroke code activations and timings during the first two months of the pandemic. MATERIAL AND METHODS We reviewed the stroke code database of a single comprehensive stroke centre in Portugal for the number of activations through 2019-2020. We compared the pathway timings between March and April 2020 (COVID-19 period) and the homologous months of the previous four years (pre-COVID-19 period), whilst using February as a control. RESULTS Monthly stroke code activation rates decreased up to 34.2% during COVID-19 pandemic. Compared to the pre-COVID-19 period, we observed an increase in the time from symptom onset to emergency call, with a significant number of patients waiting more than four hours (March 20.8% vs. 6.8%, p = 0.034; April 23.8% vs. 6%, p = 0.01); as well as an increase in the time from symptom onset to hospital arrival (March: median 136 minutes [IQR 106-410] vs. 100 [IQR 64-175], p = 0.001; April: median 188 [IQR 96-394] vs. 98 [IQR 66-168], p = 0.007). No difference between both periods was found concerning in-hospital times, patient characteristics, stroke/mimic diagnosis, stroke severity, and mortality. CONCLUSION COVID-19 related factors probably reduced healthcare services utilization, and delayed emergency calls and hospital arrival after stroke onset. These highlight the importance of health education to improve the effectiveness of medical assistance. The preservation of in-hospital times validates the feasibility of the protected stroke code protocol.

Abstract
Coastal communities and infrastructure need protection from flooding and wave overtopping events. Assessment of hazard prediction methods, used in sea defence design, defence performance inspections and forecasting services, requires observations at the land-sea interface but these are rarely collected. Here we show how a database of hindcast overtopping events, and the conditions that cause them, can be built using qualitative overtopping information obtained from social media. We develop a database for a case study site at Crosby in the Northwest of England, use it to test the standard methods applied in operational flood forecasting services and new defence design, and suggest improvements to these methods. This novel approach will become increasingly important to deliver long-term, cost-effective coastal management solutions as sea-levels rise and coastal populations grow. At sites with limited, or no, monitoring or forecasting services, this approach, especially if combined with citizen science initiatives, could underpin the development of simplified early warning systems.

Abstract
The age at which women have their first child is increasing. This change represents a major health problem to society because advanced maternal age is related with a decay in fertility and an increase in the incidence of a variety of pregnancy complications and offspring health issues. The ovary stands as the main contributor for female reproductive ageing because of the progressive age-related decrease in follicle number and oocyte quality. Loss of redox homeostasis and establishment of an ovarian oxidative microenvironment are seen as major underlying causes for such downfall and impairment of ovarian function. Thus, the use of antioxidants to preserve fertility became an important field of research. In this review, new insights on mechanisms underlying the establishment of oxidative stress and its repercussions on ovarian ageing are addressed, along with the current state of knowledge on antioxidant supplementation and its contribution for healthy ageing and extension of ovarian lifespan.

Abstract
African swine fever virus (ASFV) causes a virulent, deadly infection in wild and domestic swine and is currently causing a pandemic covering a contiguous geographical area from Central and Eastern Europe to Asia. No commercial vaccines are available to prevent African swine fever (ASF), resulting in devastating economic losses to the swine industry. The most advanced vaccine candidates are live attenuated strains developed using a genetically modified virulent parental virus. Recently, we developed a vaccine candidate, ASFV-G-ΔI177L, by deleting the I177L gene from the genome of the highly virulent ASFV pandemic strain Georgia (ASFV-G). ASFV-G-ΔI177L is safe and highly efficacious in challenge studies using parental ASFV-G. Large-scale production of ASFV-G-ΔI177L has been limited because it can replicate efficiently only in primary swine macrophages. Here, we present the development of an ASFV-G-ΔI177L derivative strain, ASFV-G-ΔI177L/ΔLVR, that replicates efficiently in a stable porcine cell line. In challenge studies, ASFV-G-ΔI177L/ΔLVR maintained the same level of attenuation, immunogenic characteristics, and protective efficacy as ASFV-G-ΔI177L. ASFV-G-ΔI177L/ΔLVR is the first rationally designed ASF vaccine candidate that can be used for large-scale commercial vaccine manufacture. IMPORTANCE African swine fever is currently causing a pandemic resulting in devastating losses to the swine industry. Experimental ASF vaccines rely on the production of vaccine in primary swine macrophages, which are difficult to use for the production of a vaccine on a commercial level. Here, we report a vaccine for ASFV with a deletion in the left variable region (LVR). This deletion allows for growth in stable cell cultures while maintaining the potency and efficacy of the parental vaccine strain. This discovery will allow for the production of an ASF vaccine on a commercial scale.

Abstract
The present work examined the oxidation and crosslinking of the anti-bacterial enzyme lysozyme (Lyso), which is present in multiple biological fluids, and released from the cytoplasmic granules of macrophages and neutrophils at sites of infection and inflammation. It is therefore widely exposed to oxidants including peroxyl radicals (ROO•). We hypothesized that exposure to ROO• would generate specific modifications and inter- and intra-protein crosslinks via radical-radical reactions. Lyso was incubated with AAPH (2,2'-azobis(2-methylpropionamidine) dihydrochloride) as a ROO• source. Enzymatic activity was assessed, while oxidative modifications were detected and quantified using electrophoresis and liquid chromatography (UPLC) with fluorescence or mass detection (MS). Computational models of AAPH-Lyso interactions were developed. Exposure of Lyso to AAPH (10 and 100 mM for 3 h, and 20 mM for 1 h), at 37 °C, decreased enzymatic activity. 20 mM AAPH showed the highest efficiency of Lyso inactivation (1.78 mol of Lyso inactivated per ROO•). Conversion of Met to its sulfoxide, and to a lesser extent, Tyr oxidation to 3,4-dihydroxyphenylalanine and diTyr, were detected by UPLC-MS. Extensive transformation of Trp, involving short chain reactions, to kynurenine, oxindole, hydroxytryptophan, hydroperoxides or di-alcohols, and N-formyl-kynurenine was detected, with Trp62, Trp63 and Trp108 the most affected residues. Interactions of AAPH inside the negatively-charged catalytic pocket of Lyso, with Trp108, Asp52, and Glu35, suggest that Trp108 oxidation mediates, at least partly, Lyso inactivation. Crosslinks between Tyr20-Tyr23 (intra-molecular), and Trp62-Tyr23 (inter-molecular), were detected with both proximity (Tyr20-Tyr23), and chain flexibility (Trp62) appearing to favor the formation of covalent crosslinks.

Abstract
Comprehensive sampling of the carbonate system in estuaries and coastal waters can be difficult and expensive because of the complex and heterogeneous nature of near-shore environments. We show that sample collection by community science programs is a viable strategy for expanding estuarine carbonate system monitoring and prioritizing regions for more targeted assessment. 'Shell Day' was a single-day regional water monitoring event coordinating coastal carbonate chemistry observations by 59 community science programs and seven research institutions in the northeastern United States, in which 410 total alkalinity (TA) samples from 86 stations were collected. Field replicates collected at both low and high tides had a mean standard deviation between replicates of 3.6 ± 0.3 μmol kg-1 (σ mean ± SE, n = 145) or 0.20 ± 0.02%. This level of precision demonstrates that with adequate protocols for sample collection, handling, storage, and analysis, community science programs are able to collect TA samples leading to high-quality analyses and data. Despite correlations between salinity, temperature, and TA observed at multiple spatial scales, empirical predictions of TA had relatively high root mean square error >48 μmol kg-1. Additionally, ten stations displayed tidal variability in TA that was not likely driven by low TA freshwater inputs. As such, TA cannot be predicted accurately from salinity using a single relationship across the northeastern US region, though predictions may be viable at more localized scales where consistent freshwater and seawater endmembers can be defined. There was a high degree of geographic heterogeneity in both mean and tidal variability in TA, and this single-day snapshot sampling identified three patterns driving variation in TA, with certain locations exhibiting increased risk of acidification. The success of Shell Day implies that similar community science based events could be conducted in other regions to not only expand understanding of the coastal carbonate system, but also provide a way to inventory monitoring assets, build partnerships with stakeholders, and expand education and outreach to a broader constituency.

Abstract
INTRODUCTION The identification, diagnosis, follow-up, and treatment of patients with secondary progressive multiple sclerosis (SPMS) show significant differences between health care professionals in Argentina. AIM To provide consensus recommendations on the management of patients with SPMS in Argentina to optimize patient care. DEVELOPMENT A panel of expert neurologists from Argentina dedicated to the diagnosis and care of multiple sclerosis patients gathered during 2019 and 2020 to carry out a consensus recommendation on the diagnosis and treatment of SPMS patients in Argentina. To achieve consensus, the methodology of 'formal consensus-RAND/UCLA method' was used. Recommendations were established based on published evidence and the expert opinion. Recommendations focused on how to define SPMS and how to follow SPMS patients. CONCLUSION The recommendations of this consensus guidelines attempt to optimize the care of SPMS patients in Argentina.

Abstract
The Doege-Potter syndrome is a rare paraneoplastic syndrome presenting with hypoglycaemia due to ectopic secretion of insulin-like growth factor II (IGF-II) from a solitary fibrous tumor. The underlying tumor can be benign or malignant and rarely present in extrapleural sites. We describe the case of a 83-year-old male diagnosed with a Doege-Potter syndrome due to a kidney tumor.

Abstract
Therapeutic deep eutectic systems (THEDES) have dramatically expanded their popularity in the pharmaceutical field due to their ability to increase active pharmaceutical ingredients (APIs) bioavailability. However, their biological performance has not yet been carefully scrutinized. Herein, THEDES based on the binary mixture of perillyl alcohol (POH) and ibuprofen (IBU) were prepared using different molar ratios. Our comprehensive strategy includes the characterization of their thermal and structural behavior to identify the molar ratios that successfully form deep eutectic systems. The in vitro solubility of the different systems prepared has demonstrated that, unlike other reported examples, the presence of the terpene did not affect the solubility of the anti-inflammatory agent in a physiological simulated media. The biological performance of the systems was studied in terms of their antimicrobial activity against a wide panel of microorganisms. The examined THEDES showed relevant antimicrobial activity against all tested microbial strains, with the exception of P. aeruginosa. A synergistic effect from the combination of POH and IBU as a eutectic system was verified. Furthermore, the cytotoxic profile of these eutectic systems towards colorectal cancer (CRC) in vitro cell models was also evaluated. The results provide the indication that the cell viability varies in a dose-dependent manner, with a selective THEDES action towards CRC cells. With tunable bioactivities in a ratio-dependent manner, THEDES enhanced the antimicrobial and anticancer properties, representing a possible alternative to conventional therapies. Therefore, this study provides foreseeable indications about the utility of THEDES based on POH and IBU as strong candidates for novel active pharmaceutical systems.

Abstract
Reproduction of Trachurus picturatus off the western Portuguese coast was studied over 1 yr. During histological analyses, the presence of Kudoa sp. was detected in advanced vitellogenic oocytes. Kudoa infections are known to cause economic loss through the induction of post-mortem liquefaction of fish muscles, but ovarian infection as reported in this study will seriously affect the reproductive potential of the species and thus impact fisheries productivity. Only females showed gonad infection which led to total degradation of advanced vitellogenic oocytes. No macroscopic, somatic or condition indices revealed differences between infected and uninfected females, rendering this infection event a concealed suppression of reproduction.

Abstract
OBJECTIVES To determine the outcome predictors of in-hospital mortality in acute total occlusion of the left main coronary artery (ATOLMA) patients referred to emergent angioplasty and to describe the clinical presentation and the long-term outcome of these patients. BACKGROUND ATOLMA is an uncommon angiographic finding that usually leads to a catastrophic presentation. Limited and inconsistent data have been previously reported regarding true ATOLMA, yet comprehensive knowledge remains scarce. METHODS This is a multicenter retrospective cohort that includes patients presenting with myocardial infarction due to a confirmed ATOLMA who underwent emergency percutaneous coronary intervention (PCI). RESULTS In the period of the study, 7930 emergent PCI were performed in the five participating centers, and 46 of them had a true ATOLMA (0.58%). At admission, cardiogenic shock was present in 89% of patients, and cardiopulmonary resuscitation was required in 67.4%. All the patients had right dominance. Angiographic success was achieved in 80.4% of the procedures, 13 patients (28.2%) died during the catheterization, and the in-hospital mortality rate was 58.6% (27/46). At one-year and at the final follow-up, 18 patients (39%) were alive, including four cases successfully transplanted. Multivariate analysis showed that postprocedural TIMI flow was the only independent predictor of in-hospital mortality (OR 0.23, (95% CI 0.1-0.36), p < 0.001). CONCLUSIONS Our study confirms that the clinical presentation of ATOLMA is catastrophic, presenting a high in-hospital mortality rate; nevertheless, primary angioplasty in this setting is feasible. Postprocedural TIMI flow resulted as the only independent predictor of in-hospital mortality. In-hospital survivors presented an encouraging outcome. ATOLMA and left dominance could be incompatible with life.
