Introduction: The EQ-5D-Y-3L is a generic measure of health-related quality of life in children and adolescents. Although the Brazilian-Portuguese EQ-5D-Y-3L version is available, there is no value set for it, hampering its use in economic evaluations. This study aimed to elicit a Brazilian EQ-5D-Y-3L value set based on preferences of the general adult population. Methods: Two independent samples of adults participated in an online discrete choice experiment (DCE) survey and a composite time trade-off (cTTO) face-to-face interview. The framing was "considering your views for a 10-year-old child". DCE data were analyzed using a mixed-logit model. The 243 DCE predicted values were mapped into the observed 28 cTTO values using linear and non-linear mapping approaches with and without intercept. Mapping approaches' performance was assessed to estimate the most valid method to rescale DCE predicted values using the model fit (R2), Akaike Information Criteria (AIC), root mean squared error (RMSE), and mean absolute error (MAE). Results: A representative sample of 1376 Brazilian adults participated (DCE, 1152; cTTO, 211). The linear mapping without intercept (R2 = 96%; AIC, − 44; RMSE, 0.0803; MAE, − 0.0479) outperformed the non-linear without intercept (R2 = 98%; AIC, − 63; RMSE, 0.1385; MAE, − 0.1320). Utilities ranged from 1 (full health) to − 0.0059 (the worst health state). Highest weights were assigned to having pain or discomfort (pain/discomfort), followed by walking about (mobility), looking after myself (self-care), doing usual activities (usual activities), and feeling worried, sad, or unhappy (anxiety/depression). Conclusion: This study elicited the Brazilian EQ-5D-Y-3L value set using a mixed-logit DCE model with a power parameter based on a linear mapping without intercept, which can be used to estimate the quality-adjusted life-years for economic evaluations of health technologies targeting the Brazilian youth population.

The diversity of natural images in terms of visual features is useful in saliency detection. The complementary visual features jointly improve the performance of salient object detection. In this paper, we introduce a novel region-based feature combination approach that utilizes the diversity of visual features over image regions for robust salient object detection. The proposed approach works in four steps: (i) region formation, (ii) feature extraction, (iii) region-wise weight learning and (iv) region-based feature combination. Region formation is carried out using simple linear iterative clustering (SLIC) algorithm. Then, the features are extracted using Boundary Connectivity (BC), Contrast Cluster (CC), and Minimum Directional Contrast (MDC) methods. These features are then used for learning weights vectors for each region. Our major contribution is in step four where a novel dynamic weighted feature combination method is proposed. In this step region-wise integration weights are obtained by using a nature inspirited optimization algorithm called Constrained Particle swarm optimization (CPSO). Then salient features are region-wise combined with their dynamic relevance for final saliency map. The proposed method is compared with eight state-of-the-art saliency detection methods on five public available saliency benchmark datasets namely MSRA10K, DUT-OMRON, ECSSD, PASCAL, and SED2. The experimental results demonstrate that the proposed method performs better than state-of-the-art methods in terms of Precision, Recall, F-measure and Mean Absolute Error while comparable in terms of AUC and ROC curve.

Robertsonian translocation 1;29 (rob(1;29)), a widespread chromosomal anomaly affecting cattle fertility, appears to have originated from a common ancestor. This study utilizes routine SNP data to investigate the chromosomal region associated with rob(1;29) and confirm the presence of a shared haplotype among carriers in diverse Italian breeds. Three datasets were employed: Dataset 1 included 151 subjects from 5 beef cattle breeds genotyped with the GGP Bovine 33 k SNP chip; Dataset 2 encompassed 800 subjects from 32 Italian breeds genotyped with the Illumina 50 k SNP chip, sourced from the BOVITA dataset; Dataset 3 combined Dataset 2 with 21 karyologically tested subjects from breeds with a high carrier frequency, genotyped using the Affymetrix 65 K SNP chip. FST analysis pinpointed a distinctive genomic region on the first six Mb of BTA29, the centromeric region involved in the translocation. Haplotype comparisons within this non-recombining region revealed a common haplotype shared among all carriers, supporting the theory of a common ancestor. Principal component and haplotype analysis allowed clear differentiation of rob(1;29) homozygous and heterozygous carriers. Expanding to Dataset 2 revealed rob(1;29) carriers in unexpected breeds, all sharing the same ancestral haplotype. Notably, previously untested breeds, including Cinisara, exhibited a high carrier prevalence (nearly 50%), confirmed by karyological analysis. This study validates the presence of a shared haplotype among all identified rob(1;29) carriers, reinforcing the common ancestor theory as the origin of this translocation's spread throughout the cattle population. Furthermore, it underscores the potential of SNP data analysis as a rapid, accurate, and cost-effective tool for broad rob(1;29) screening, given the translocation's consistent nature across all analyzed breeds.

This study aimed at evaluating the efficacy of different radiotherapy (RT) fractionation regimens in managing uncomplicated painful bone metastases (BM) and identifying predictive factors for pain control. Patients with 1 to 4 symptomatic BM from any primary solid tumors and a life expectancy exceeding 3 months were included in the study and received palliative RT, with SBRT restricted in the context of oligometastatic disease or in patients with good prognosis. Pain analysis using the Brief Pain Inventory (BPI) tool was conducted at baseline, 1 and 3 months after RT. Analgesic intake was recorded as morphine-equivalent doses (OME). Pain response was assessed using the International Consensus on Palliative Radiotherapy Endpoint (ICPRE). Multivariate logistic regression analyzed patient-related, tumor-related, and treatment-related factors predicting BM pain control at 3 months post-RT. From Feb 2022 to Feb 2023, 44 patients with 65 symptomatic BM were investigated. Breast (32%) and lung (24%) tumors were the most common primary tumors. Treatment plans included 3DCRT (60%) and VMAT (40%), with a median biological effective dose for tumors (BED) of 29 Gy [14–108]. All patients completed the 3-month follow-up. Pain response rates were 62% at 1 month and 60% at 3 months. Responders had better PS ECOG scores (67%; P = 0.008) and received active systemic therapies (67%: P = 0.036). Non-responders had lower pretreatment BPI (mean: 13.7 vs. 58.2; P = 0.032), with significantly higher values after 1 month (mean: 9.1 vs. 5.3, P = 0.033). Baseline BPI (OR: 1.17; 95% CI: 1.032–1.327; P = 0.014) and BPI at 1 month (OR: 0.83; 95% CI: 0.698–0.976; P = 0.025) were independent predictors of pain response at 3 months. Our findings show that palliative RT ensured short-term pain control in patients with BM, regardless of tumor type and dose-fractionation regimen. A larger sample size and a longer follow-up could potentially identify which patients are likely to benefit most from RT, and which fractionation might be indicated for achieving a durable pain relief. A multidisciplinary approach is paramount to provide a better care to BM patients. [ABSTRACT FROM AUTHOR]

Sign language recognition is one of the fundamental ways to assist deaf people to communicate with others. An accurate vision-based sign language recognition system using deep learning is a fundamental goal for many researchers. Deep convolutional neural networks have been extensively considered in the last few years, and a slew of architectures have been proposed. Recently, Vision Transformer and other Transformers have shown apparent advantages in object recognition compared to traditional computer vision models such as Faster R-CNN, YOLO, SSD, and other deep learning models. In this paper, we propose a Vision Transformer-based sign language recognition method called DETR (Detection Transformer), aiming to improve the current state-of-the-art sign language recognition accuracy. The DETR method proposed in this paper is able to recognize sign language from digital videos with a high accuracy using a new deep learning model ResNet152 + FPN (i.e., Feature Pyramid Network), which is based on Detection Transformer. Our experiments show that the method has excellent potential for improving sign language recognition accuracy. For instance, our newly proposed net ResNet152 + FPN is able to enhance the detection accuracy up to 1.70% on the test dataset of sign language compared to the standard Detection Transformer models. Besides, an overall accuracy 96.45% was attained by using the proposed method. [ABSTRACT FROM AUTHOR]

Purpose: To investigate prevalence and predictors of renal function variation in a multicenter cohort treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Methods: Patients from 17 tertiary centers were included. Renal function variation was evaluated at postoperative day (POD)—1, 6 and 12 months. Timepoints differences were Δ1 = POD-1 eGFR − baseline eGFR; Δ2 = 6 months eGFR − POD-1 eGFR; Δ3 = 12 months eGFR − 6 months eGFR. We defined POD-1 acute kidney injury (AKI) as an increase in serum creatinine by ≥ 0.3 mg/dl or a 1.5 1.9-fold from baseline. Additionally, a cutoff of 60 ml/min in eGFR was considered to define renal function decline at 6 and 12 months. Logistic regression (LR) and linear mixed (LM) models were used to evaluate the association between clinical factors and eGFR decline and their interaction with follow-up. Results: A total of 576 were included, of these 409(71.0%) and 403(70.0%) had an eGFR < 60 ml/min at 6 and 12 months, respectively, and 239(41.5%) developed POD-1 AKI. In multivariable LR analysis, age (Odds Ratio, OR 1.05, p < 0.001), male gender (OR 0.44, p = 0.003), POD-1 AKI (OR 2.88, p < 0.001) and preoperative eGFR < 60 ml/min (OR 7.58, p < 0.001) were predictors of renal function decline at 6 months. Age (OR 1.06, p < 0.001), coronary artery disease (OR 2.68, p = 0.007), POD-1 AKI (OR 1.83, p = 0.02), and preoperative eGFR < 60 ml/min (OR 7.80, p < 0.001) were predictors of renal function decline at 12 months. In LM models, age (p = 0.019), hydronephrosis (p < 0.001), POD-1 AKI (p < 0.001) and pT-stage (p = 0.001) influenced renal function variation (ß 9.2 ± 0.7, p < 0.001) during follow-up. Conclusion: Age, preoperative eGFR and POD-1 AKI are independent predictors of 6 and 12 months renal function decline after RNU for UTUC. [ABSTRACT FROM AUTHOR]

Purpose: Loss of smell decreases the quality of life and contributes to the failure in recognizing hazardous substances. Given the relevance of olfaction in daily life, it is important to recognize an undiagnosed olfactory dysfunction to prevent these possible complications. Up to now, the prevalence of smell disorders in Italy is unknown due to a lack of epidemiological studies. Hence, the primary aim of this study was to evaluate the prevalence of olfactory dysfunction in a sample of Italian adults. Methods: Six hundred and thirty-three participants (347 woman and 286 men; mean age 44.9 years, SD 17.3, age range 18–86) were recruited from 10 distinct Italian regions. Participants were recruited using a convenience sapling and were divided into six different age groups: 18–29 years (N = 157), 30–39 years (N = 129), 40–49 years (N = 99), 50–59 years (N = 106), > 60 years (N = 142). Olfactory function, cognitive abilities, cognitive reserve, and depression were assessed, respectively, with: Sniffin' Sticks 16-item Odor Identification Test, Montreal Cognitive Assessment, Cognitive Reserve Index, and the Beck Depression Inventory. Additionally, socio-demographic data, medical history, and health-related lifestyle information were collected. Results: About 27% of participants showed an odor identification score < 12 indicating hyposmia. Multiple regression analysis revealed that OI was significantly correlated with age, sex, and cognitive reserve index, and young women with high cognitive reserve index showing the highest olfactory scores. Conclusion: This study provides data on the prevalence of olfactory dysfunction in different Italian regions. [ABSTRACT FROM AUTHOR]

Purpose: Behavioral interventions have been used with breast cancer survivors (BCS) in cancer pain management and post-treatment quality of life (QOL) studies. We studied the effects of an anti-inflammatory dietary intervention on QOL in BCS.Methods: One hundred fifty-three overweight and obese (body mass index [BMI] ≥ 25 kg/m2), early stage (0-III), English-speaking BCS who had completed all cancer treatment 2 or more months prior to enrollment were recruited into a two-arm randomized controlled trial with a 2 (group) by 3 (time) repeated measures design. Intervention components included six monthly food-preparation workshops and twelve motivational interviewing telephone calls. Endpoints included the Perceived Stress Scale (PSS), the Functional Assessment of Cancer Therapy-General (FACT-G) and Breast Cancer (FACT-B), and the Center for Epidemiologic Studies Depression Scale (CES-D). Repeated measures analysis using PROC MIXED in SAS version 9.4 was used.Results: On repeated measures analysis (intent to treat), there were no differences between groups on any of the QOL outcomes except the PSS total scores. These were significantly different in the intervention group (IG; n = 76) compared to control group (CG; n = 77), showing a main effect of assignment but no effect of time and no interaction effects.Conclusion: There was an impact on QOL as measured by the PSS between groups. The intervention reduced perceived stress at 6-month follow-up, but the effects dissipated by 12 months. Sources and stress and stress reduction should be a focus of future studies. Future research should also identify appropriate QOL measures that are sensitive to changes brought about by behavioral interventions. [ABSTRACT FROM AUTHOR]

Introduction: Withholding uninitiated actions and cancelling ongoing ones are two main components of response inhibition, a key element of the executive control. Inhibitory performance is sensitive to emotional contexts elicited by subliminal and supraliminal visual material. However, whether stimuli from other sensory modalities, such as odours, would equally modulate response inhibition remains unclear. Here, we aimed to assess the effect of task-irrelevant odours as a function of their valence and threshold on both action withholding and action cancellation of reach-to-press movements. Method: Thirty-two healthy participants performed a Go/No-Go task that included the presentation of pleasant (orange) and unpleasant (trimethyloxazole) odour primes at supra- and sub-threshold levels; clean air was included as a control condition. The reach-to-press responses were composed of an initial release phase and a subsequent reaching phase. Results: Only the supra-threshold pleasant (vs. control) odour impaired action withholding. Moreover, the pleasant (vs. control) odour—presented at both sub- and supra-threshold levels—elicited more accurate Go responses, whereas the sub- and supra-threshold pleasant and unpleasant (vs. control) odours triggered faster responses in the release phase. Additionally, only the supra-threshold pleasant (vs. unpleasant) odour impaired action cancellation in the reaching phase. Furthermore, reaching responses were slower following the supra-threshold unpleasant (vs. control) odour. Conclusions: Our findings extend the sparse literature on the impact of odour stimuli on goal-directed behaviour, highlighting the role of both odour valence and threshold in the modulation of response inhibition. Implications: Determining the mechanisms by which odour stimuli modulate response inhibition lays the foundations for research on odour-triggered disinhibition. [ABSTRACT FROM AUTHOR]

Both anxiety and autism spectrum disorder (ASD) are associated with atypical physiological activity. Few studies have systematically assessed the resting physiological activity in ASD with co-occurring anxiety disorders. We tested 75 participants divided in four groups: youth with ASD, with (ASD + Anxiety = 22, 6F, 12.29 ± 2.83 years old) and without co-occurring anxiety (ASD Alone = 15, 6F, 11.59 ± 2.85 years old) and compared their physiological profile with that of matched typically developing controls (TDC) with (Anxiety Alone = 16, 6F, 11.24 ± 3.36 years old) and without co-occurring anxiety disorders (TDC = 22, 8F, 11.88 ± 2.88 years old). Results indicated reduced sympathetic and parasympathetic activity at rest in ASD as compared to TDC youth. ASD + Anxiety and Anxiety Alone groups showed different sympathetic, but similar parasympathetic activity. These findings suggest that autonomic profile-based approaches may advance research, diagnosis, and treatment of ASD and anxiety. [ABSTRACT FROM AUTHOR]

Economic instability, social changes, and new social policies place economic insecurity high on the scholarly and political agenda. We contribute to these debates by proposing a new multidimensional, intertemporal measure of economic insecurity that accounts for both its multiplicity and its dynamism. First, we develop three theory-driven, multidimensional measures of economic insecurity. Principal Components Analysis validates the measure. Second, we develop a dynamic approach to insecurity, using longitudinal data and a newly revised headcount method. Third, we then use our new measures to analyze the distribution of insecurity in Europe. Our analysis shows that insecurity is widespread across Europe, even in low-inequality, encompassing welfare states. Moreover, it extends across income groups and occupational classes, reaching into the middle classes. [ABSTRACT FROM AUTHOR]

Chemosensory impairments have been established as a specific indicator of COVID-19. They affect most patients and may persist long past the resolution of respiratory symptoms, representing an unprecedented medical challenge. Since the SARS-CoV-2 pandemic started, we now know much more about smell, taste, and chemesthesis loss associated with COVID-19. However, the temporal dynamics and characteristics of recovery are still unknown. Here, capitalizing on data from the Global Consortium for Chemosensory Research (GCCR) crowdsourced survey, we assessed chemosensory abilities after the resolution of respiratory symptoms in participants diagnosed with COVID-19 during the first wave of the pandemic in Italy. This analysis led to the identification of two patterns of chemosensory recovery, partial and substantial, which were found to be associated with differential age, degrees of chemosensory loss, and regional patterns. Uncovering the self-reported phenomenology of recovery from smell, taste, and chemesthetic disorders is the first, yet essential step, to provide healthcare professionals with the tools to take purposeful and targeted action to address chemosensory disorders and their severe discomfort.

This article aims to study the mechanical strength and fire resistance of polyurethane/cement (PuCem) composites containing glass sludge and sludge from aluminum anodizing. Scanning electron microscopy (SEM) results showed that the replacement of 24.5% of the cement with sand (San), aluminum anodizing (Aas), or glass-polishing sludge (Gla) maintained the alveolar structure in the composites. Also, energy-dispersive X-ray spectroscopy and FTIR analyses showed that the cement hydration reaction forms hydrated aluminates and silicates. ANOVA–Tukey tests showed that the PuCemAas composites' areas are significantly different from those of PuCemGla and PuCemSan, which are similar to each other. The compressive strength decreases upon replacing cement with the aggregates. The TGA thermograms were similar for the four composites and the polyurethane matrix. The specimens were declassified in the vertical and horizontal position (UL-94). Thus, the composites were an alternative for reducing the use of raw materials from non-renewable sources.

Left ventricle, LV wringing wall motion relies on physiological muscle fiber orientation, fibrotic status, and electromechanics (EM). The loss of proper EM activation can lead to rigid-body-type (RBT) LV rotation, which is associated with advanced heart failure (HF) and challenges in resynchronization. To describe the EM coupling and scar tissue burden with respect to rotational patterns observed on the LV in patients with ischemic heart failure with reduced ejection fraction (HFrEF) left bundle branch block (LBBB). Thirty patients with HFrEF/LBBB underwent EM analysis of the left ventricle using an invasive electro-mechanical catheter mapping system (NOGA XP, Biosense Webster). The following parameters were evaluated: rotation angle; rotation velocity; unipolar/bipolar voltage; local activation time, LAT; local electro-mechanical delay, LEMD; total electro-mechanical delay, TEMD. Patients underwent late-gadolinium enhancement cMRI when possible. The different LV rotation pattern served as sole parameter for patients' grouping into two categories: wringing rotation (Group A, n = 6) and RBT rotation (Group B, n = 24). All parameters were aggregated into a nine segment, three sector and whole LV models, and compared at multiple scales. Segmental statistical analysis in Group B revealed significant inhomogeneities, across the LV, regarding voltage level, scar burdening, and LEMD changes: correlation analysis showed correspondently a loss of synchronization between electrical (LAT) and mechanical activation (TEMD). On contrary, Group A (relatively low number of patients) did not present significant differences in LEMD across LV segments, therefore electrical (LAT) and mechanical (TEMD) activation were well synchronized. Fibrosis burden was in general associated with areas of low voltage. The rotational behavior of LV in HF/LBBB patients is determined by the local alteration of EM coupling. These findings serve as a strong basic groundwork for a hypothesis that EM analysis may predict CRT response. Clinical trial registration: SUM No. KNW/0022/KB1/17/15. [ABSTRACT FROM AUTHOR]

The human sense of smell is still much underappreciated, despite its importance for vital functions such as warning and protection from environmental hazards, eating behavior and nutrition, and social communication. We here approach olfaction as a sense of well-being and review the available literature on how the sense of smell contributes to building and maintaining well-being through supporting nutrition and social relationships. Humans seem to be able to extract nutritional information from olfactory food cues, which can trigger specific appetite and direct food choice, but may not always impact actual intake behavior. Beyond food enjoyment, as part of quality of life, smell has the ability to transfer and regulate emotional conditions, and thus impacts social relationships, at various stages across life (e.g., prenatal and postnatal, during puberty, for partner selection and in sickness). A better understanding of how olfactory information is processed and employed for these functions so vital for well-being may be used to reduce potential negative consequences.

Introduction: High tibial osteotomy (HTO) was a treatment option for relatively young active patients with isolated medial compartment arthritis of the knee. This report showed clinical and radiological results of a new HTO technique, that uses a particular open-wedge high tibial osteotomy by incorporating the tibial tubercle into osteotomy line (TT-OWHTO) to preserve patella height. Materials and methods: Preoperative and postoperative function was recorded on the IKDC score, Kujala PF score, EQ-VAS and Tegner activity scale. Radiological patella height was measured with Insall–Salvati index. All this clinical and radiological recorded data on 45 active patients, with an average age of 40.2 years who underwent this procedure, allowed to do a retrospective analysis. Results: All the patients reported improvement in symptoms with an average preoperative IKDC score from preoperative value 49.7–92.3 at last follow-up. Kujala PF score improves from 67.2 preoperative value to 91.4. EQ-VAS self-assessment of quality of life reported a preoperative value of 41.2–92.2 at last follow-up. There was 2.5 point average improvement in Tegner activity scale. Patella height was not altered with median preoperative value of 0.84 ± 0.1 and final follow-up value of 0.81 ± 0.2 on Insall–Salvati index. Conclusions: TT-OWHTO showed to be able to achieve good clinical and radiological results maintaining patella height unchanged and ensuring safety and reproducibility as much as the traditional technique.

Background: Epithelial-to-mesenchymal transition (EMT) enhances motility, stemness, chemoresistance and metastasis. Little is known about how various pathways coordinate to elicit EMT's different functional aspects in non-small cell lung cancer (NSCLC). Thymidylate synthase (TS) has been previously correlated with EMT transcription factor ZEB1 in NSCLC and imparts resistance against anti-folate chemotherapy. In this study, we establish a functional correlation between TS, EMT, chemotherapy and metastasis and propose a network for TS mediated EMT.Methods: Published datasets were analysed to evaluate the significance of TS in NSCLC fitness and prognosis. Promoter reporter assay was used to sort NSCLC cell lines in TSHIGH and TSLOW. Metastasis was assayed in a syngeneic mouse model.Results: TS levels were prognostic and predicted chemotherapy response. Cell lines with higher TS promoter activity were more mesenchymal-like. RNA-seq identified EMT as one of the most differentially regulated pathways in connection to TS expression. EMT transcription factors HOXC6 and HMGA2 were identified as upstream regulator of TS, and AXL, SPARC and FOSL1 as downstream effectors. TS knock-down reduced the metastatic colonisation in vivo.Conclusion: These results establish TS as a theranostic NSCLC marker integrating survival, chemo-resistance and EMT, and identifies a regulatory network that could be targeted in EMT-driven NSCLC.

A 71-day study was conducted to explore the effect of increasing dietary levels (0, 250, 500, 1000 mg kg feed−1; D0, D250, D500 and D1000, respectively) of a blend of microencapsulated organic acids (OA, specifically citric and sorbic acid) and nature identical compounds (NIC, specifically thymol and vanillin), on growth, intestinal immune parameters and gut microbiota (GM) of European sea bass juveniles reared under normal and subsequently suboptimal environmental conditions (high temperature, 30.0 ± 0.4 °C and low oxygen, 4.6 ± 0.6 mg L−1). OA and NIC did not promote growth, feed utilisation and feed intake at the inclusion tested but induced a significantly upregulation of IL-8, IL-10 and TGFβ. GM analyzed by next-generation sequencing showed that OA and NIC were able to exert prebiotic properties stimulating the development of beneficial bacteria taxa such as Lactobacillus, Leuconostoc, and Bacillus sp. Picrust analyses displayed a significant potential functional reconfiguration of GM promoting a decrease in inflammation-promoting and homeostatic functions at increasing OA and NIC administration. For the first time on this species the exposure to suboptimal rearing conditions was able to modify GM structure reducing LAB and increasing Proteobacteria, findings which were consistent with the inflammatory process observed at mRNA level.

Introduction: Lower urinary tract symptoms (LUTS) in subjects with Mayer-Rokitansky-Küster-Hauser syndrome treated by Davydov's laparoscopic neo-vaginoplasty were measured. Methods: Davydov's laparoscopic neo-vaginoplasty was undertaken at the Department of Obstetrics/gynecology, San Raffaele Hospital, Milan, Italy, from November 2015 to July 2017, by two highly qualified surgeons. All women completed the ICIQ-UI Short Form questionnaire before and after treatment. LUTS were scored at recruitment, hospitalization, and 1, 3, 6 and 12 months after surgery. Results: Twenty-one women (mean age 21 years ± 5.9) were operated on with no major complications. Mean surgery duration was 79 min (± 55 min). Before the operation, one patient (1/21; 4.8%) reported occasional urinary loss that persisted after surgery and throughout 12 months of follow-up. After the operation, one patient (1/21; 4.8%) had urinary retention, requiring self-catheterization for 2 weeks. One month after surgery, stress incontinence was recorded in one case (1/19; 5.2%) and urge incontinence in two cases (2/19; 10.5%). At 3-month follow-up, these three patients were free of symptoms. Conclusion: The rate of LUTS is lower than that reported by others using alternative surgical procedures. To the best of our knowledge, this is the first report validating LUTS after Davydov's neo-vaginoplasty. [ABSTRACT FROM AUTHOR]

Global food demand is rising, and serious questions remain about whether supply can increase sustainably1. Land-based expansion is possible but may exacerbate climate change and biodiversity loss, and compromise the delivery of other ecosystem services2–6. As food from the sea represents only 17% of the current production of edible meat, we ask how much food we can expect the ocean to sustainably produce by 2050. Here we examine the main food-producing sectors in the ocean—wild fisheries, finfish mariculture and bivalve mariculture—to estimate 'sustainable supply curves' that account for ecological, economic, regulatory and technological constraints. We overlay these supply curves with demand scenarios to estimate future seafood production. We find that under our estimated demand shifts and supply scenarios (which account for policy reform and technology improvements), edible food from the sea could increase by 21–44 million tonnes by 2050, a 36–74% increase compared to current yields. This represents 12–25% of the estimated increase in all meat needed to feed 9.8 billion people by 2050. Increases in all three sectors are likely, but are most pronounced for mariculture. Whether these production potentials are realized sustainably will depend on factors such as policy reforms, technological innovation and the extent of future shifts in demand. Modelled supply curves show that, with policy reform and technological innovation, the production of food from the sea may increase sustainably, perhaps supplying 25% of the increase in demand for meat products by 2050.

In response to the COVID-19 pandemic, many governments have taken drastic measures to avoid an overflow of intensive care units. Accurate metrics of disease spread are critical for the reopening strategies. Here, we show that self-reports of smell/taste changes are more closely associated with hospital overload and are earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators. We also report a decrease in self-reports of new onset smell/taste changes as early as 5 days after lockdown enforcement. Cross-country comparisons demonstrate that countries that adopted the most stringent lockdown measures had faster declines in new reports of smell/taste changes following lockdown than a country that adopted less stringent lockdown measures. We propose that an increase in the incidence of sudden smell and taste change in the general population may be used as an indicator of COVID-19 spread in the population. Syndromic surveillance for COVID-19 could help to identify areas with increasing transmission. Here, the authors show that increased reports of changes in smell and taste measured at the population level are correlated with the increased COVID-19-related hospital admissions.

Participatory approaches to fisheries management are gaining increasing support from researchers, non-governmental organizations, and governments in Latin America, and different forms of participatory monitoring have been implemented over the last few decades. Among several advantages, these initiatives allow incorporation of fishers' knowledge on ecology, fishing practices, social aspects, markets, regulations, into different stages of management. In this paper, we analyze key features of participatory monitoring programs in small-scale coastal fisheries in South America (Argentina, Brazil, Chile and Uruguay) through a literature review complemented by expert opinion. Our review considered the fisheries and variables monitored; objectives, duration, institutional context of the monitoring programs; and factors that affect the extent of fishers' participation and the incorporation of fishers' knowledge. We found 14 case studies described in the literature, most of which correspond to benthic fisheries. Most cases focused on ecological and/or catch and effort variables; few initiatives included social variables. Initiatives were mainly driven by researchers in partnership with fishers and other stakeholders under formal or informal institutional arrangements. Institutional arrangements were largely responsible for the effectiveness of participation. In most cases, fishers' participation in monitoring was fostered as a component of a broader participatory co-management approach. Despite the challenges, participatory monitoring approaches are gaining traction in South America, receiving significant support from researchers in most cases, and from nongovernmental organizations in some cases. Increased governmental support for implementing and sustaining long-lasting participatory monitoring programs would strengthen monitoring initiatives that emerge locally. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to evaluate the outcomes of transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BiAV) stenosis using a mechanically expanded Lotus™ device. The prior experience with first-generation devices showed disappointing results mainly due to increased prevalence of aortic regurgitation (AR) that exceeded those observed in tricuspid stenosis. Methods and results: We collected baseline, in-hospital, 30-day and 2-year follow-up data from a prospective, multicentre registry of patients with BiAV undergoing TAVI using Lotus™ valve. Safety and efficacy endpoints were assessed according to VARC-2 criteria. The study group comprised 24 patients. The mean age was 73.5 years and the mean EuroSCORE 2 was 4.35 ± 2.56%. MDCT analysis revealed Type 1 BiAV in 75% of patients. The mean gradient decreased from 60.1 ± 18.3 to 15 ± 6.4 mm Hg, the AVA increased from 0.6 ± 0.19 to 1.7 ± 0.21 cm2. One in-hospital death was observed secondary to aortic perforation. There was no severe AR and the rate of moderate AR equalled 9% at 30 days (n = 2). Device success was achieved in 83% and the 30-day safety endpoint was 17%. In the 2-year follow-up, the overall mortality was 12.5% and the 2-year composite clinical efficacy endpoint was met in 25% of the patients (n = 6) Conclusions: The TAVI in selected BiAV patients using the Lotus™ is feasible and characterized by encouraging valve performance and mid-term clinical outcomes.

Despite its popularity, the construct of biological motion (BM) and its putative anomalies in autism spectrum disorder (ASD) are not completely clarified. In this article, we present a meta-analysis investigating the putative anomalies of BM perception in ASD. Through a systematic literature search, we found 30 studies that investigated BM perception in both ASD and typical developing peers by using point-light display stimuli. A general meta-analysis including all these studies showed a moderate deficit of individuals with ASD in BM processing, but also a high heterogeneity. This heterogeneity was explored in different additional meta-analyses where studies were grouped according to levels of complexity of the BM task employed (first-order, direct and instrumental), and according to the manipulation of low-level perceptual features (spatial vs. temporal) of the control stimuli. Results suggest that the most severe deficit in ASD is evident when perception of BM is serving a secondary purpose (e.g., inferring intentionality/action/emotion) and, interestingly, that temporal dynamics of stimuli are an important factor in determining BM processing anomalies in ASD. Our results question the traditional understanding of BM anomalies in ASD as a monolithic deficit and suggest a paradigm shift that deconstructs BM into distinct levels of processing and specific spatio-temporal subcomponents.

Behçet's syndrome (BS) is an autoimmune, rare, and severe multisystemic inflammatory disease characterized by recurrent oral aphthous ulcers, genital ulcers, skin lesions, and both anterior and posterior uveitis; articular, vascular, gastroenteric and neurological involvement may also occur. The multi-organ involvement and the wide range of clinical spectrum make the diagnosis of BS challenging. As other systemic chronic diseases, BS can affect all aspects of patients' life, including sexual dysfunction (SD). So far, SD has been deeply studied among patients affected by many rheumatic diseases; however, little is known about the prevalence and the characteristics of SD among BS patients. The present work was aimed at providing a systematic literature review of the literature published on SD and BS. We carried out a systematic search in PubMed and Scopus based on controlled terms (MeSH) and keywords to identify literature data on SD in BS. The systematic search was independently performed by two clinicians based on the controlled medical subject heading terms for Behcet syndrome and SD. Systematic database search identified 32 records. Screening by title and abstract was then conducted and a total of 10 articles were eligible for full text assessment, five studies explored SD in male patients with BS, 3 studies in females and 2 works reported data on both genders. Globally, the systematic literature review results have underlined that SD seems frequent in BS patients. Both female and male patients experienced a significant correlation between SD and depression. The studies investigating sexuality in BS seem to demonstrate that in these patients SD may be mainly related to depression rather than to active organic manifestations. [ABSTRACT FROM AUTHOR]

Whether emotional stimuli influence both response readiness and inhibition is highly controversial. Visual emotional stimuli appear to interfere with both under certain conditions (e.g., task relevance). Whether the effect is generalisable to salient yet task-irrelevant stimuli, such as odours, remains elusive. We tested the effect of orthonasally-presented pleasant (orange) and unpleasant odours (trimethyloxazole and hexenol) and clean air as a control on response inhibition. In emotional Go/No-Go paradigms, we manipulated the intertrial interval and ratios of Go/No-Go trials to account for motor (Experiment 1, N = 31) and cognitive (Experiment 2, N = 29) response inhibition processes. In Experiment 1, participants had greater difficulty in withholding and produced more accurate and faster Go responses under the pleasant vs. the control condition. Faster Go responses were also evident in the unpleasant vs. the control condition. In Experiment 2, neither pleasant nor unpleasant odours modulated action withholding, but both elicited more accurate and faster Go responses as compared to the control condition. Pleasant odours significantly impair action withholding (as compared to the control condition), indicating that more inhibitory resources are required to elicit successful inhibition in the presence of positive emotional information. This modulation was revealed for the motor aspect of response inhibition (fast-paced design with lower Go/No-Go trial ratio) rather than for attentional interference processes. Response readiness is critically impacted by the emotional nature of the odour (but not by its valence). Our findings highlight that the valence of task-irrelevant odour stimuli is a factor significantly influencing response inhibition. [ABSTRACT FROM AUTHOR]

Since its shutdown in 1979, L-54M nuclear research reactor of Politecnico di Milano has been kept in safe storage configuration. In view of forthcoming decommissioning activities, many characterization activities have been performed on its matrices. Regarding the L-54M graphite stack, a neutron activation model was developed and validated by a graphite sampling and preliminary radiological characterization campaign focused on the most significant gamma-emitting radionuclides. Even if slightly underestimating the measured values, between − 5% and − 49% for 152Eu, between − 41% and − 67% for 154Eu, the simulated activity concentrations promisingly reproduce the experimental radial profile.

An antibiotic-producing actinobacterium, designated isolate B375T, was isolated from marine sponge Glodia corticostylifera collected from Praia Guaecá, São Paulo, Brazil (23°49S; 45°25W), and its taxonomic position established using data from a polyphasic study. The organism showed a combination of morphological, physiological, biochemical and chemotaxonomic characteristics consistent with its classification in the genus Williamsia. Comparative 16S rRNA gene sequence analysis indicated that the strain B375T was most closely related to Williamsia serinedens DSM 45037T and Williamsia spongiae DSM 46676T and having 99.43% and 98.65% similarities, respectively, but was distinguished from these strains by a low level of DNA–DNA relatedness (53.2–63.2%) and discriminatory phenotypic properties. Chemotaxonomic investigations revealed the presence of cell-wall chemotype IV and N-glycolated muramic acid residues present in the wall cells. The cells contained C16:0 (23.3%), C18:0 10-methyl (23.2%) and C18:1 ω9c (21.6%) as the major cellular fatty acids. The strain B375T inhibited growing of Staphylococcus aureus and Colletotrichum gloeosporioides strains and was considered a producer of antimicrobial compounds. Based on the data obtained, the isolate B375T (= CBMAI 1090T = DSM 46677T) should, therefore, be classified as the type strain of a novel species of the genus Williamsia, for which the name Williamsia aurantiacus sp. nov. is proposed.

To investigate the safety and efficacy of an early platelet function testing (PFT)-guided de-escalation of dual antiplatelet treatment (DAPT) in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) with bioresorbable vascular scaffolds (BVS). Early DAPT de-escalation is a new non-inferior alternative to 12-months DAPT in patients with biomarker positive ACS treated with stent implantation. In this post-hoc analysis of the TROPICAL-ACS trial, which randomized 2610 ACS patients to a PFT-guided DAPT de-escalation (switch from prasugrel to clopidogrel) or to control group (uniform prasugrel), we compared clinical outcomes of patients (n = 151) who received a BVS during the index PCI. The frequency of the primary endpoint (cardiovascular death, myocardial infarction, stroke or BARC ≥ 2 bleeding) was 8.8% (n = 6) in the de-escalation group vs. 12.0% (n = 10) in the control group (HR 0.72, 95% CI 0.26–1.98, p = 0.52) at 12 months. One early definite stent thrombosis (ST) occurred in the control group (day 19) and 1 possible ST (sudden cardiovascular death) in the de-escalation group (day 86), both despite prasugrel treatment and in a background of high on-treatment platelet reactivity assessed at day 14 after randomization (ADP-induced platelet aggregation values of 108 U and 59 U, respectively). A PFT-guided DAPT de-escalation strategy could potentially be a safe and effective strategy in ACS patients with BVS implantation but the level of platelet inhibition may be of particular importance. This hypothesis-generating post-hoc analysis requires verification in larger studies with upcoming BVS platforms. [ABSTRACT FROM AUTHOR]

Purpose: The goal of this education and culinary-based dietary intervention was to increase adherence to a Mediterranean-style, anti-inflammatory dietary pattern in breast cancer survivors (BCS) by promoting the consumption of anti-inflammatory foods, herbs, and spices.Methods: Overweight and obese, early-stage, BCS were randomized to the Intervention (n = 76) or Control (n = 77). The 6-month intervention included monthly nutrition and cooking workshops, Motivational Interviewing telephone calls, and individualized newsletters. Control participants received monthly informational brochures and no navigational services. Dietary intakes were collected via questionnaire and 3-day food records at baseline and 6 months.Results: One hundred twenty-five BCS (n = 60 I; n = 65 C) completed post-testing (81.7%) and were included in analyses. Adherence to Mediterranean diet guidelines significantly increased in the intervention group, but not in the control group (+ 22.5% vs. + 2.7%, P < 0.001). Upon further analysis of adherence to individual dietary guidelines, the intervention group significantly improved adherence to only three guidelines: consuming ≥ 3 servings of fish or shellfish/week, reducing red meat intake to < 1 serving/day, and limiting consumption of commercial sweets and baked goods to < 3 times/week. The intervention arm increased the use of spices and herbs compared to control (+ 146.2% vs. +33.3%, P < 0.001), including significantly more frequent consumption of cinnamon, turmeric, garlic, ginger, black pepper, and rosemary.Conclusion: An education and culinary-based intervention in BCS successfully increased adherence to a more Mediterranean-style, anti-inflammatory dietary pattern by increasing the consumption of anti-inflammatory foods, spices, and herbs and decreasing the consumption of pro-inflammatory foods.

Rapid developments in the field of processors and radio technology have provided the context of small sensor nodes which are able to communicate in wireless sensor networks. But data security is restricted by these factors. An intelligent trust management plan needs to be applied for detection of the reliability of sensor nodes to distinguish between malicious nodes from other nodes. In this paper a trust-based energy-aware routing algorithm has been proposed. Considering direct and indirect trust of nodes and energy saving issue, the routing function metrics are optimized by Gravitational Search Approach. This routing method is called Energy-aware Trust-based Gravitational Search Approach (ETGSA). Simulation has been done by NS-2 and it is shown that the main characteristics such as reduction of computational overhead and increasing reliability against of attacks in the network are improved compared with other efficient algorithms in this field.

Since shut-down, Politecnico di Milano managed L-54 M nuclear research reactor according to deferred dismantling strategy. Recently, decommissioning activities have been started with preliminary radiological characterization, even though a more extended campaign would be required. In this work, a Monte Carlo N-Particle 3D model of the reactor has been proficiently developed to estimate graphite stack activation. To verify the model accuracy, several simulated criticality data have been satisfactorily compared with experimental ones, validating this computational approach as valid support to forthcoming radiological characterization campaign.

Members of the genus Bradyrhizobium are well-known as nitrogen-fixing microsymbionts of a wide variety of leguminous species, but they have also been found in different environments, notably as endophytes in non-legumes such as sugarcane. This study presents a detailed polyphasic characterization of four Bradyrhizobium strains (type strain BR 10280), previously isolated from roots of sugarcane in Brazil. 16S rRNA sequence analysis, multilocus sequence analysis (MLSA) and analysis of the 16S-23S rRNA internal transcribed spacer showed that these strains form a novel clade close to, but different from B. huanghuaihaiense strain CCBAU 23303. Average nucleotide identity (ANI) analyses confirmed that BR 10280 represents a novel species. Phylogenetic analysis based on nodC gene sequences also placed the strains close to CCBAU 23303, but different from this latter strain, the sugarcane strains did not nodulate soybean, although they effectively nodulated Vigna unguiculata, Cajanus cajan and Macroptilium atropurpureum. Physiological traits are in agreement with the placement of the strains in the genus Bradyrhizobium as a novel species for which the name Bradyrhizobium sacchari sp. nov. is proposed.
