RESUMO

Microplastics (MPs) (0.1 µm-5 mm particles) have been documented in oceans and seas. Bivalve molluscs (BMs) can accumulate MPs and transfer to humans through the food chain. BMs (especially mussels) are used to assess MPs' contamination, but the genus Donax has not been thoroughly investigated. The aim of this study was to detect and characterize MPs in D. trunculus specimens collected along the Tuscan coast (Italy), and to assess the potential risk for consumers. The samples (~10 g of tissue and intervalval liquid from 35 specimens) were digested using a solution of 10% KOH, subjected to NaCl density separation, and filtered through 5 µm pore-size filters. All items were morphologically classified and measured, and their mean abundance (MA) was calculated. Furthermore, 20% of them were analyzed by Raman spectroscopy and, based on the obtained results, the MA was recalculated (corrected MA) and the annual human exposure was estimated. In the 39 samples analyzed, 85 items fibers (n = 45; 52.94%) and fragments (n = 40; 47.06%) were found. The MA was 0.23 ± 0.17 items/grww. Additionally, 83.33% of the items were confirmed as MPs (polyethylene and polyethylene terephthalate). Based on the correct MA (0.18 MPs/grww), D. trunculus consumers could be exposed to 19.2 MPs/per capita/year. The health risk level of MPs was classified as level III (moderate).

RESUMO

Food authentication using molecular techniques is of great importance to fight food fraud. Metabarcoding, based on the next-generation sequencing (NGS) technologies, allowing large-scale taxonomic identification of complex samples via massive parallel sequencing of fragments (called DNA barcodes) simultaneously, has become increasingly popular in many scientific fields. A systematic review to answer the question "Is the metabarcoding ripe enough to be applied to the authentication of foodstuff of animal origin?" is presented. The inclusion criteria were focused on the selection of scientific papers (SPs) only applying metabarcoding to foodstuff of animal origin collected on the market. The 23 included SPs were first analyzed with respect to the metabarcoding phases: library preparation (target genes, primer pairs, and fragment length), sequencing (NGS platforms), and final data analysis (bioinformatic pipelines). Given the importance of primer selection, the taxonomic coverage of the used primers was also evaluated. In addition, the SPs were scored based on the use of quality control measures (procedural blanks, positive controls, replicates, curated databases, and thresholds to filter the data). A lack of standardized protocols, especially with respect to the target barcode/s and the universal primer/s, and the infrequent application of the quality control measures, leads to answer that metabarcoding is not ripe enough for authenticating foodstuff of animal origin. However, the observed trend of the SP quality improvement over the years is encouraging. Concluding, a proper protocol standardization would allow a wider use of metabarcoding by both official and private laboratories, enabling this method to become the primary for the authentication of foodstuffs of animal origin.

RESUMO

Pufferfish (Tetraodontidae) inhabiting the Mediterranean Sea may represent an emerging public health risk due to the possible accumulation of marine neurotoxins such as tetrodotoxin (TTXs) and saxitoxin (STXs) in their tissues. In this study, the presence of pufferfish species in the Strait of Sicily (Lampedusa Island, Italy) was investigated using a citizen science (CS) approach, involving local fishermen. Samples (liver, intestine, gonads, muscle, skin) from 20 specimens were sent to the National Reference Laboratory on Marine Biotoxins for TTXs detection using a validated HILIC-MS/MS method on fish tissue. The presence of STXs was also screened in part of the specimens. Overall, 56 specimens identified as Sphoeroides pachygaster (Müller &Troschel, 1848) were collected. Data on their total length, body weight, fishing method and catch area (with relative depth temperature and salinity) were analyzed and compared with the S. pachygaster records reported in literature which were updated to 2022. All the analysed tissues were found to be negative for both TTXs and STXs. CS played an essential role in monitoring potentially toxic marine species in this investigation. Outcomes from this study, which is the first investigating S. pachygaster toxicity in Italian waters, may provide useful data for the proper assessment of this emerging risk.

RESUMO

Background: Balance, i.e., the ability not to fall, is often poor in neurological patients and this impairment increases their risk of falling. The Mini-Balance Evaluation System Test (Mini-BESTest), a rating scale, the Timed Up and Go (TUG) test, and gait measures are commonly used to quantify balance. This study assesses the criterion validity of these measures as balance measures. Methods: The probability of being a faller within nine months was used as the balance criterion. The Mini-BESTest, TUG (instrumented with inertial sensors), and walking test were administered before and after inpatient rehabilitation. Multiple and LASSO logistic regressions were used for the analysis. The diagnostic accuracy of the model was assessed with the area under the curve (AUC) of the receiver operating characteristic curve. Mobility measure validity was compared with the Akaike Information Criterion (AIC). Results: Two hundred and fourteen neurological patients (stroke, peripheral neuropathy, or parkinsonism) were recruited. In total, 82 patients fell at least once in the nine-month follow-up. The Mini-BESTest (AUC = 0.69; 95%CI: 0.62-0.76), the duration of the TUG turning phase (AUC = 0.69; 0.62-0.76), and other TUG measures were significant faller predictors in regression models. However, only the turning duration (AIC = 274.0) and Mini-BESTest (AIC = 276.1) substantially improved the prediction of a baseline model, which only included fall risk factors from the medical history (AIC = 281.7). The LASSO procedure selected gender, disease chronicity, urinary incontinence, the Mini-BESTest, and turning duration as optimal faller predictors. Conclusion: The TUG turning duration and the Mini-BESTest predict the chance of being a faller. Their criterion validity as balance measures in neurological patients is substantial.

RESUMO

The discovery of a pufferfish specimen (Tetraodontidae) inside a frozen cuttlefish, purchased by a fishmonger, and caught in the Eastern Central Atlantic (FAO 34) is reported. The consumer, who reported this case to FishLab (Department of Veterinary Sciences, University of Pisa) for investigation, was a student of Veterinary Medicine at the University of Pisa. He recognized the Tetraodontidae because he attended practical lessons on fish morphological identification during the course of food inspection and was aware of the risks to human health linked to the Tetrodotoxin (TTX). In this study, the pufferfish was identified morphologically, using the FAO morphological keys, and molecularly, analyzing two markers, the cytochrome oxidase I (COI) and the cytochrome b genes, by DNA barcoding. The pufferfish was identified morphologically as Sphoeroides spp., and molecularly as Sphoeroides marmoratus using the COI gene (99-100% identity values). Literature reports that S. marmoratus from the Eastern Atlantic contains high concentrations of TTX in the gonads and the digestive tract. However, the possible passage of TTX from fish to other organisms linked to contact or ingestion has never been reported. This represents the first case of a potentially toxic pufferfish entering the market inside another organism. The fact that a student observed this occurrence highlights the key role of citizen science in the management of emerging risks.

RESUMO

Neck proprioception is commonly assessed with head repositioning tests. In such a test, an operator rotates the head of a blindfolded individual to a target position. After returning to the rest position, the participant actively repositions the head to the target. Joint Position Error (JPE) is the angular difference between the target angle (however oriented in a 3D space) and the actively reached positions (the smaller the difference, the better the proprioception). This study aimed to validate a head-to-target (HTT) repositioning test using an optoelectronic system for also measuring the components of the JPE in the horizontal, frontal, and sagittal planes. The head movements requested by the operator consisted of 30° left-right rotations and 25° flexion-extension. The operators or subjects could not obtain these movements without modest rotations in other planes. Two operators were involved. Twenty-six healthy participants (13 women) were recruited (mean (SD): 33.4 (6.3) years). The subjects' JPE in the requested (intended) plane of motion (JPEint-component) was a few degrees only and smaller for flexion-extensions than for left-right rotations (right rotation: 5.39° (5.29°); left rotation: 5.03° (4.51°), extension: 1.79° (3.94°); flexion: 0.54° (4.35°)). Participants' average error in unintended planes was around 1° or less. Inter-operator consistency and agreement were high. The smallest detectable change, at p < 0.05, for JPEint-component ranged between 4.5° and 6.98°. This method of optoelectronic measurement in HTT repositioning tests provides results with good metric properties, fostering application to clinical studies.

RESUMO

PURPOSE: The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). MATERIALS AND METHODS: All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. RESULTS: During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. CONCLUSION: RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization.

RESUMO

BACKGROUND: In asymptomatic carotid stenosis (ACS), different plaque types, i.e. lipidic (LP), fibrous (FP), and calcific (CP), could have different hemodynamic and structural behaviors. METHODS: Different carotid plaques, reconstructed from medical imaging of ACS >70%, were analyzed by computing fluid structure interaction (FSI), modeling the spatial distribution of wall shear stresses (WSS), plaque displacements (D), von Mises stresses (VMS), and absorbed elastic energy (AEE) together with their maximum-in-space values at the systole (WSSsyst, Dsyst, VMSsyst and AEEsyst). RESULTS: WSS resulted significantly higher in CP, whereas D and VMS showed the highest values for LP. Regarding AEEsyst stored by the plaques, LP absorbed in average 2320 J/m3, FP 408 J/m3 (470%) and CP 99 J/m3 (2240%), (P<0.01, P<0.01, and P<0.01, respectively). CONCLUSIONS: Depending upon their nature, plaques store different deformations and inner distributions of forces, thus potentially influencing their vulnerability.

RESUMO

Quality of life (QoL) in patients with chronic venous disorders has a central role to decide the correct treatment approach. In particular, in case of mini-invasive therapy, such as endovenous radiofrequency ablation (RFA), the postoperative QoL improvement remains one of the most important outcome to be reached. Despite this, very few data are published on the long-term QoL modifications after RFA. The aim of this brief report is to describe and analyze the role of QoL scales in a population of patients treated with RFA of the great saphenous vein and phlebectomies, highlighting results in short- and long-term follow-up period, and differences between recanalized and non-recanalized patients.

RESUMO

OBJECTIVE: The aim of this study is to compare and to test the performance of all available risk scoring systems (RSSs) designed to predict long-term survival rate in asymptomatic candidate patients for carotid endarterectomy (CEA) for significant carotid artery stenosis. METHODS: Data on asymptomatic patients who underwent CEA in three high-volume centers were prospectively recorded. Through literature research using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, six RSSs were identified for the intent of the study. Primary endpoints were 3- and 5-year survival rates after CEA. All items used as variables to compose multiple RSSs were applied to every patient in the study population. The 3- and 5-year mortality prediction rates for each score were assessed by sensitivity, specificity, and predictive negative and positive value calculation, as well as univariable Cox proportional hazard models with the Harrell C index. RESULTS: During the study period, 825 CEAs in 825 asymptomatic patients were analyzed. All items used in RSSs were available in the dataset, with some concerns regarding their definition and application among RSSs. The 3- and 5-year survival rates of the study cohort were 94.5% and 90.3%, respectively. Among the six RSSs analyzed, no RSS demonstrated optimal results in terms of mortality rate prediction accuracy, although some scores had good diagnostic and risk of death precision. CONCLUSIONS: RSSs, when used alone, fail to optimally detect postoperative life expectancy in asymptomatic CEA patient candidates. Further prospective controlled studies are needed to compose and validate RSSs with better calibration to predict outcomes.

RESUMO

Although rare, central post-stroke pain remains one of the most refractory forms of neuropathic pain. Repetitive transcranial magnetic stimulation (rTMS) has been reported to be effective in chronic cases. However, there are no data on the effects in the acute and subacute phases after stroke. In this study, we present a case of a patient with thalamic stroke with acute onset of pain and paresthesia who was responsive to rTMS. After a right thalamic stroke, a 32-year-old woman presented with drug-resistant pain and paresthesia on the left side of the body. There were no motor or sensory deficits, except for blunted thermal sensation and allodynia on light touch. Ten daily sessions were performed, where 10 Hz rTMS was applied to the hand area of the right primary motor cortex, 40 days after stroke. Before rTMS treatment (T0), immediately after treatment conclusion (T1), and 1 month after treatment (T2), three pain questionnaires were administered, and cortical responses to single and paired-pulse TMS were assessed. Eight healthy participants served as controls. At T0, when the patient was experiencing the worst pain, the excitability of the ipsilesional motor cortex was reduced. At T1 and T2, the pain scores and paresthesia' spread decreased. The clinical improvement was paralleled by the recovery in motor cortex excitability of the affected hemisphere, in terms of both intra- and inter-hemispheric connections. In this subacute central post-stroke pain case, rTMS treatment was associated with decreased pain and motor cortex excitability changes.

RESUMO

The relative displacements of body segments during walking can be reduced to a small number of multi-joint kinematic patterns, pmk, through Principal Component Analysis (PCA). These patterns were extracted from two groups of children (n = 8, aged 6-9 years, 4 males, and n = 8, aged 10-13 years, 4 males) and 7 adults (21-29 years, 1 male), walking on a treadmill at various velocities, normalized to body stature (adimensional Froude number, Fr). The three-dimensional coordinates of body markers were captured by an optoelectronic system. Five components (pm1 to pm5) explained 99.1% of the original dataset variance. The relationship between the variance explained ("size") of each pmk and the Fr velocity varied across movement components and age groups. Only pm1 and pm2, which described kinematic patterns in the sagittal plane, showed significant differences (at p < 0.05) across pairs of age groups. The time course of the size of all the five components matched various mechanical events of the step cycle at the level of both body system and lower limb joints. Such movement components appeared clinically interpretable and lend themselves as potential markers of neural development of walking.

RESUMO

The acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the COVID-19 disease, a global pandemic. A strong association has been documented between COVID-19 and cardiovascular events, although the exact pathophysiological mechanism is still unclear. Carotid atherothrombosis and ischemic stroke represents one of the possible severe manifestations of COVID-19, as a leading cause of long-term disability and death. Different complex intertwined mechanisms seem to underlie the endothelitis which is the cause of multiple cardiovascular manifestations. To date, few case series describing COVID-19 and acute ischemic stroke caused by cervical carotid thrombosis have been published. All the patients shared common similar radiographic features, comorbidities, and biomarker profiles. The aim of this brief review was to analyze the impact of COVID-19 pandemic in the management of a Vascular Surgery Department, changing the daily vascular practice, as well as to provide practical suggestions for symptomatic carotid stenosis, while reviewing published literature.

RESUMO

During walking, falling is most likely to occur towards the side of the supporting lower limb during the single stance. Timely lateral redirection of the centre of mass (CoM) preceding the no-return position is necessary for balance. We analysed the curvature peaks (the inverse of the radius of curvature) of the three-dimensional path of the CoM during the entire stride. Twelve healthy adults walked on a force-sensorized treadmill at constant velocities from 0.4 to 1.2 m s-1, in 0.2 m s-1 increments. The three-dimensional displacements of the CoM, the muscular power sustaining the CoM motion with respect to the ground, and the efficiency of the pendulum-like transfer of the CoM were computed via the double integration of the ground reaction forces. The curvatures of the CoM trajectory were measured (Frenet-Serret formula). During the single stance, the curvature showed a bell-shaped increment, lasting a few tenths of a millisecond, and peaking at 365-683 m-1 (radius of 2.7-1.4 mm, respectively), the higher the walking velocity. The CoM was redirected towards the swinging lower limb. The curvature increment was sustained by muscle-driven braking of the CoM. Smoother increments of curvature (peaking at approximately 37-150 m-1), further orienting the CoM towards the leading lower limb, were observed during the double stance. The peaks of the curvatures were symmetric between the two sides. The high curvature peaks during the single stance may represent an index of dynamic balance during walking. This index might be useful for both rehabilitation and sports training purposes.

RESUMO

ABSTRACT: Walking on split-belt treadmills (each belt rotating at a different velocity) has inspired a growing number of researchers to study gait adaptation and rehabilitation. An overlooked peculiarity of this artificial form of gait is that the mean velocity adopted by the participant, considered as a whole system represented by the body Center of Mass, can be different from the mean velocity of the two belts. Twelve healthy adults (21-34 yrs) were requested to walk for 15 mins on a treadmill with belts rotating at 0.4 and 1.2 m sec-1, respectively (mean = 0.8 m sec-1). Each belt was supported by four 3-dimensional force sensors. For each participant, six strides were analyzed during the 1st and the 15th minute of the trial. The mean Center of Mass velocity was computed as the sum of the velocities of each belt weighted by the percentage of time during which the resulting forces, underlying the accelerations of the Center of Mass, originated from each belt. Across early and late observations, the median Center of Mass velocities were 0.72 and 0.67 m sec-1, respectively (P < 0.05). Therefore, the real velocity of the Center of Mass and its time course should be individually assessed when studying walking on split-belt treadmills.

RESUMO

Atherosclerosis is a systemic disease that leads to accumulation of deposits, known as atherosclerotic plaques, within the walls of the carotids. In particular, three types of plaque can be distinguished: soft, fibrous, and calcific. Most of the computational studies who investigated the interplay between the plaque and the blood flow on patient-specific geometries used nonstandard medical images to directly delineate and segment the plaque and its components. However, these techniques are not so widely available in the clinical practice. In this context, the aim of our work was twofold: (i) to propose a new geometric tool that allowed to reconstruct a plausible plaque in the carotids from standard images and (ii) to perform three-dimensional (3D) fluid-structure interaction (FSI) simulations where we compared some fluid-dynamic and structural quantities among 15 patients characterized by different typologies of plaque. Our results highlighted that both the morphology and the mechanical properties of different plaque components play a crucial role in determining the vulnerability of the plaque.

RESUMO

BACKGROUND: In the current literature, correlations between a contralateral carotid artery occlusion (CCO) with mortality and major adverse cardiac or cerebrovascular events (MACCE) rates after carotid artery stenting (CAS) are often described with controversial conclusions. Moreover, long-term results of mortality, MACCE and restenosis rate are scarcely reported. This study examined the association between a CCO and the short- and long-term outcomes after CAS. METHODS: One hundred and forty-six patients with CCO and without (No-CCO) who underwent between 2010 and 2017 to a CAS procedure in a single institution were retrospectively evaluated. The primary aim of the study was to evaluate mortality and MACCE rates in the short-term (defined as the occurrence during hospitalization and within 30-day) and after 3-year follow-up. The secondary aim of the study was to examine the restenosis rates in the short- and long-term period. RESULTS: The overall success of CAS was 99.3% and the 30-day all-cause mortality rate was 0.7% (one death). About MACCE, there were no major strokes in the CCO groups and 1 (1.4%) in the No-CCO group (P=1.00). The rate of 30-day minor strokes was 1.4% (1 patient) in the CCO group and 2.7% (2 patients) in the No-CCO group (P=1.00). In the 3-year follow-up, death occurred in 11 CCO vs. 6 No-CCO patients, respectively (15.1% vs. 8.2%, P=0.30). Regarding MACCE, major stroke occurred in 6 CCO vs. 2 No-CCO patients (8.2% vs. 2.7%, P=0.27), minor stroke in 6 CCO vs. 6 No-CCO (8.2% vs. 8.2%, P=1.0) and myocardial infarction in 6 CCO (8.2%) vs. 3 No-CCO patients (8.2 vs. 4.1%, P=0.49), respectively. Regarding the 30-day restenosis rate, it was observed in one patient (1.4%) in the CCO group while no cases were recorded in the No-CCO group, respectively (P=1.00). In the 3-year follow-up, greater than >50% restenosis was observed in 7 patients (9.6%) in the CCO group and in one patient (1.4%) in the No-CCO group (P=0.06), respectively. Kaplan-Meier survival analysis revealed that CCO patients had a lower 3-year freedom from restenosis rate with respect to the No-CCO group (87.6% vs. 98.6%, P=0.024). A Cox regression model on 3-year restenosis highlighted female gender and hypertension to be statistically significant predictors of restenosis. CONCLUSIONS: Patients with a preexisting CCO did not show a significative increased risk of procedural adverse events after CAS both in the immediate and long-term follow-up, but on the long term they are more likely to experience restenosis. CCO condition should be considered always as a clinical manifestation of a more aggressive carotid atherosclerosis.

RESUMO

BACKGROUND: The aim of this study was to investigate the influence of the aortic arch type on technical and clinical success of carotid artery stenting (CAS) procedure. METHODS: Clinical and anatomical data of consecutive patients who underwent CAS from 2010 to 2018 were prospectively collected and retrospectively analyzed. Primary outcome was technical success, define as successful stent delivery and deployment and <30% residual carotid stenosis. Secondary outcomes were death, stroke, myocardial infarction (MI) and transient ischemic attack (TIA) rates at 30 days after CAS. Subgroups analysis with asymptomatic and symptomatic patients were also performed. RESULTS: During the study period, 523 patients were enrolled and analyzed. Among these, 176 (33.6%) had Type I, 227 (43.4%) had Type II and 120 (23.0%) had Type III or bovine aortic arch (BAA) type. Technical success rate was achieved in 96.0% of cases. At 30 days, if compared with Type I or II, patient with Type III or BAA experienced a higher death rate (0 vs. 0 vs. 1.8%, respectively; P=0.056) and combined postoperative stroke/TIA rate (3% vs. 2.8% vs. 9.9%, respectively; P=0.012). No differences for same outcomes between asymptomatic and symptomatic patients were described, although the latter group experienced more postoperative MI. A multivariate analysis revealed Type III or BAA as an independent risk factor for postoperative stroke/TIA (HR 3.23, IC95% 1.40-7.45; P=0.006). CONCLUSIONS: In this cohort of patients, death and postoperative neurological complications rates were associated with Type III or BAA, irrespective of symptomatic patients' status. Extremely attention is required during perioperative period in patients who were candidate to CAS and with challenging aortic arch anatomy.

RESUMO

BACKGROUND: Patients with symptomatic carotid stenosis recently treated with percutaneous transluminal coronary angioplasty (PTCA) for acute coronary syndrome (ACS) are always classified as at high risk for surgery, given that they are required uninterrupted dual antiplatelet therapy. In this regard, carotid artery stenting (CAS) may represent a valid alternative. OBJECTIVE: The purpose of this study is to overview CAS outcomes in symptomatic patients with and without ACS. METHODS: One hundred fifty-one consecutive symptomatic patients who underwent CAS between 2010 and 2017 in a single institution were included in this study, of which 66 (43.7%) were identified as having ACS. All patients were followed-up with carotid duplex ultrasound scan and a neurological assessment of symptoms status at 30-day postprocedure and at 3, 6, and 12 months, with annual follow-up after that for 3 years. RESULTS: Among symptomatic ACS patients, common risks factors were active smoking, metabolic syndrome, diabetes, and hypertension. In the short-term follow-up, no significant differences were observed among rates of death, stroke, myocardial infarction (MI), and restenosis, between patients with and without ACS. Mean clinical follow-up was 28.2 (12.3) months. In the long-term follow-up, higher rates of death and MI were recorded in patients with ACS (death: 11.4% vs. 5.4%, p = .04; MI: 11.4% vs. 3.6%, p = .02), owing to the complexity of these patients. CONCLUSIONS: This single-center study suggested that CAS is a safe and effective treatment for patients with symptomatic carotid artery stenosis, who recently underwent PTCA for ACS, requiring uninterrupted dual antiplatelet therapy.
