The cognitive neuropsychiatry of Tourette syndrome

ABSTRACT Introduction: Converging evidence from both clinical and experimental studies has shown that Tourette syndrome (TS) is not a unitary condition, but a cluster of multiple phenotypes, which encompass both tics and specific behavioural and cognitive symptoms (mainly attention-deficit and hyperactivity disorder and obsessive-compulsive disorder). Methods: We conducted a narrative review of the recent literature on the cognitive neuropsychiatry of TS. Results: Although clinical research has shown that TS is not associated with cognitive deficits per se, the findings of recent studies have suggested the presence of subtle alterations in specific cognitive functions. A promising line of research on imitative behaviour could provide a common background for the alterations in executive control and social cognition observed in TS. Two different (but not mutually exclusive) neurocognitive theories have recently suggested that TS could originate from altered perception-action binding and social decision-making dysfunction, respectively. Conclusions: Since the presence of behavioural comorbidities influences individualised treatment approaches, it is likely that a more precise characterisation of TS phenotypes, including cognitive aspects, will result in improved levels of care for patients with tic disorders.
Participation of TRPV1 in the activity of the GnRH system in male rats

GnRH neuron activity is under the influence of multiple stimuli, including those coming from the endocannabinoid and the immune systems. Since it has been previously suggested that some of the main elements controlling the GnRH pulse generator possess the TRPV1 receptor, the aim of the present study was to evaluate the participation of the hypothalamic TRPV1, through its pharmacological blockade, in the activity of the hypothalamic‐pituitary‐testicular axis in male rats under basal or acute inflammatory conditions. Our hypothesis was based on the idea that the hypothalamic TRPV1 participates in the synthesis of the main neuromodulatory signals controlling GnRH, and therefore the reproductive axis. Our results showed that the hypothalamic TRPV1 blockade induced pro‐inflammatory effects by increasing Tnfα and Il‐1β mRNA hypothalamic levels and inhibited the reproductive axis by affecting Gnrh, Kiss1 and Rfrp3 mRNA levels and decreasing plasma levels of luteinizing hormone and testosterone under basal conditions, without significant additive effects in rats exposed to systemic LPS. Altogether, these results suggest that the hypothalamic TRPV1 receptor participates in the regulation of the GnRH system, probably by modulating immune‐dependent mechanisms.
Knowledge and Behaviors Toward COVID-19 Among US Residents During the Early Days of the Pandemic: Cross-Sectional Online Questionnaire

Abstract Objective: To test the hypothesis that knowledge of COVID-19 influences participation in different behaviors including self-reports of purchasing more goods than usual, attending large gatherings, and using medical masks. Methods: Cross-sectional online survey of 1,034 U.S. residents age 18+ conducted on March 17, 2020. Results: For every point increase in knowledge, the odds of participation in purchasing more goods (OR=0.88, 95% CI:0.81-0.95), attending large gatherings (OR=0.87, 95%CI: 0.81-0.93), and using medical masks (OR=0.56, 95% CI:0.50-0.62) decreased by 12%, 13%, and 44%, respectively. Gen X and Millennial participants had 56% to 76% higher odds, respectively, of increased purchasing behavior, compared to Baby Boomers. Results suggest politicization of response recommendations. Democrats had 30% lower odds of attending large gatherings (OR=0.70, 95% CI:0.50-0.97), and 48% lower odds of using medical masks (OR=0.52, 95% CI:0.34-0.78), compared to Republicans. Conclusions: This survey is one of the first attempts to study determinants of knowledge and behaviors in response to the COVID-19 pandemic in the U.S. A national, coordinated effort at pandemic response may ensure better compliance with behavioral recommendations to address this public health emergency.
Ocean Surface Drifting Buoy System Based on UAV-Enabled Wireless Powered Relay Network

We design an ocean surface drifting buoy system based on an unmanned aerial vehicle (UAV)-enabled wireless powered relay network in which the UAV acts as mobile hybrid access point that broadcasts energy to all buoys in the downlink and forwards information from the buoys to a ship signal tower (ST) in the uplink. In order to maximize the resource allocation efficiency of the system, due to the different initial energy reserve of the buoys, a novel communication mode selection strategy is proposed. In the direct transmission mode (DT mode), an energy-sufficient buoy transmits information directly to the ST, and in the relay transmission mode (RT mode), an energy-insufficient buoy relays information to the ST through the UAV. By applying the block coordinate descent and successive convex optimization, a joint UAV trajectory and resource allocation algorithm is proposed to maximize the minimum throughput of the buoys to work in the RT mode. Simulation results show that the proposed algorithm can significantly improve the minimum throughput of the ocean surface drifting buoys.
SEASONAL EFFECT ON THE RELATIONSHIP BETWEEN THE PHOTOSYNTHETIC CAPACITY OF INTERTIDAL MICROPHYTOBENTHOS AND TEMPERATURE 1

The response of the photosynthetic capacity (Pmax) of microphytobenthos to short‐term variations of temperature (in the range 5–35° C) was assessed on a seasonal basis. The relationship is described mathematically, and relevant physiological parameters are identified: PMAX, the maximum value of Pmax achieved at Topl, the optimum temperature. Estimated values of Topt do not change significantly throughout the year and remain close to 25° C. It is thus concluded that Topt is not influenced by seasonal variations in the daily range of mud surface temperature. Identical conclusions hold for Tmax (ca. 38° C), the thermal threshold beyond which no photosynthesis occurs. Conversely, PMA estimates exhibit substantial variability: PMAX (mean ± root mean square error) is highest in April (11.18 ± 0.42 [μg C · [μg Chl a]−1· h−1) during the beginning of the annual increase in temperature, photoperiod, and maximum irradiance and is lowest in December (3.04 ± 0.16 μg C · [μg Chl a]−1· h−l). From an ecological point of view, the short‐term and seasonal variations of PMAX suggest that the microphytobenthic community takes advantage of the abiotic spring environmental conditions, allowing the onset of the bloom. Nevertheless, no “acclimation strategy” (i.e. shifts in Topt and Tmax that prevent temperature inhibition in summer or improve photosynthetic rates in winter) is apparent from our results.
Does Smoking Cessation at Primary Diagnosis Reduce the Recurrence Risk of Nonmuscle-Invasive Bladder Cancer? Results of a Prospective Study

Introduction: Evidence that smoking cessation at first diagnosis of nonmuscle-invasive bladder cancer (NMIBC) reduces the risk of recurrence is lacking. The aim of our prospective study was to analyze the association between patients’ changes in smoking habits after diagnosis and recurrence-free survival (RFS). Patients: After transurethral resection of primary NMIBC, patients were classified as “ex-smokers,” i.e., those definitively stopping, and as “active smokers,” i.e., those continuing or restarting to smoke. Smoking status was reassessed every 3 months during the first year and every 6 months thereafter. Data on patients’ demographics, smoking status, tumor characteristics, treatments, and follow-up were collected. Statistical analysis was performed adopting SPSS 15.0. 1 and R3.4. 2 software. Results: Out of 194 patients, 67 (34.5%) quit smoking after the diagnosis, while 127 (65.5%) did not. The clinical and pathological characteristics were homogeneously distributed. At a median follow-up of 38 months, 106 patients (54.6%) recurred, 33 (49.2%) ex- and 73 (60.3%) active smokers with a 3-year RFS of 42.3 and 50.7%, respectively (p = 0.55). No statistically significant association between recurrence, pathological features of the primary tumor, and patient smoking habits after diagnosis was detected. Results were not statistically influenced by the intensity (cigarette/day) and duration (years) of smoking. In multivariate analysis, cigarette smoking cessation at diagnosis did not significantly reduce tumor recurrence. Conclusion: In our prospective study, more than half of our patients recurred at 3 years. In multivariate analysis, smoking cessation did not significantly reduce tumor recurrence. However, the 8.4% reduction in favor of the ex-smokers suggests the need of larger studies with longer follow-ups. Surprisingly, only 35% of smokers definitively quit after diagnosis. The urologists should play a more active role to persuade the patients to stop smoking at first cancer diagnosis.
Machine learning goes wild: Using data from captive individuals to infer wildlife behaviours

Remotely tracking distinct behaviours of animals using acceleration data and machine learning has been carried out successfully in several species in captive settings. In order to study the ecology of animals in natural habitats, such behaviour classification models need to be transferred to wild individuals. However, at present the development of those models usually requires direct observation of the target animals. The goal of this study was to infer behaviour of wild, free roaming animals from acceleration data by training behaviour classification models on captive individuals, without the necessity to observe their wild conspecifics. We further sought to develop methods to validate the credibility of the resulting behaviour extrapolations. We trained two machine learning algorithms proposed by the literature, Random Forest (RF) and Support Vector Machine (SVM), on data from captive red foxes (Vulpes vulpes) and later applied them to data from wild foxes. We also tested a new advance for behaviour classification, by applying a moving window to an Artificial Neural Network (ANN). Finally, we investigated four strategies to validate our classification output. While all three machine learning algorithms performed well under training conditions, the established methods, RF and SVM, failed in classifying distinct behaviours when transferred from captive to wild foxes. Behaviour classification with the ANN and a moving window, in contrast, inferred distinct behaviours and showed consistent results for most individuals. Our approach is a substantial improvement over the methods previously proposed in the literature as it generated plausible results for wild fox behaviour. We were able to infer the behaviour of wild animals that have never been observed in the wild and to further illustrate the outputs credibility. This framework is not restricted to foxes but can be applied to infer the behaviour of many other species and thus empowers new advances in behavioural ecology.
A Qualitative View of Homecare Support Workers on Unmet Health Needs of People with Dependency

Background: Longevity and population growth generate an increase in the number of people with dependency, who require homecare assistance to meet their health needs. Homecare support workers provide this care in Spain, and they may have unique insights into the unmet health needs of those receiving homecare assistance. The aim of this study was to determine the unmet health needs of people with dependency based on the perspective of homecare support workers. Methods: Qualitative exploratory-descriptive study. Through convenience sampling, homecare support workers from a Spanish province were selected, following inclusion and exclusion criteria. Four focus groups, transcription and thematic analyses were performed using Atlas.ti. Coding triangulation was carried out, applying criteria for scientific rigour. Results: The six themes obtained were classified into the material, psychoemotional, socioeconomical and psychosocial needs of people with dependency from the point of view of homecare support workers, along with the contributions of improvements and the need of these professionals for continuous training. Conclusions: People with dependency need complex technical assistance, materials, psychological attention due to their situation, and more effective assessments of their health and disability status. Homecare support workers perceive themselves to be essential in these assessments. They ask for psychological assistance, due to the emotional burden of their work, and believe this help would contribute to improving the quality of their service. Homecare support workers perceive that they are capable of performing their job, although they believe that some delegated activities are beyond their levels of competency.
Physicians’ perceptions of the uptake of biosimilars: a systematic review

Objectives To examine physicians’ perceptions of the uptake of biosimilars. Design Systematic review. Data sources MedLine Ovid and Scopus databases at the end of 2018. Eligibility criteria Original scientific studies written in English that addressed physicians’ perceptions of the uptake of biosimilars. Data extraction and synthesis The search resulted in altogether 451 studies and 331 after removing duplicates. Two researchers examined these based on the title, abstract and entire text, resulting in 20 studies. The references in these 20 studies were screened and three further studies were included. The data of these 23 studies were extracted. All the publications were quality assessed by two researchers. Results Most of the selected studies were conducted in Europe and commonly used short surveys. Physicians’ familiarity with biosimilars varied: 49%–76% were familiar with biosimilars while 2%–25% did not know what biosimilars were, the percentages varying from study to study. Their measured knowledge was generally more limited compared with their self-assessed knowledge. Physicians’ perceptions of biosimilars also varied: 54%–94% were confident prescribing biosimilars, while 65%–67% had concerns regarding these medicines. Physicians seemed to prefer originator products to biosimilars and prescribed biosimilars mainly for biologic-naive patients. They considered cost savings and the lower price compared with the originator biologic medicine as the main advantages of biosimilars, while their doubts were often related to safety, efficacy and immunogenicity. 64%–95% of physicians had negative perceptions of pharmacist-led substitution of biologic medicines. Conclusions Physicians’ knowledge of and attitudes towards biosimilars vary. Although physicians had positive attitudes towards biosimilars, prescribing was limited, especially for patients already being treated with biologic medicines. Perceptions of pharmacist-led substitution of biologic medicines were often negative. Education and national recommendations for switching and substitution of biologic medicines are needed to support the uptake of biosimilars.
Neural substrates of sexual arousal revisited: Dependent on sex

Challenging previous work (1), a recent metaanalysis suggests “that the neuronal circuitries activated by visual sexual stimuli are independent of biological sex” (ref. 2, p. 15671). Neuroimaging metaanalyses are indispensable for robust conclusions on neuronal correlates of mental functions (3). To attain this goal, best-practice guidelines have been jointly proposed by the developers of all major analytic approaches (3). A careful look at the aforementioned analysis reveals several issues that may have affected the outcome in nontrivial ways. The authors performed contrast analyses “to combinatorically compare ALE [activation likelihood estimation] datasets in a pairwise manner, in particular with respect to … sex” (ref. 2, p. 15675). According to their appendix and laudably shared dataset, experiments comprising mixed samples (i.e., men and women) might have been assigned to both sex-specific metaanalyses that were eventually compared, obscuring potential sex differences. Another 11% of experiments did not report within-sex brain activations but reported group comparisons, sample size information seemed off for about 25%, and … [↵][1]1To whom correspondence may be addressed.

Energy requirements during reproduction of Peromyscus maniculatus

Weight-specific food consumption, gross daily energy consumption, and weights of breeding groups, lactating females, and young litters were monitored between time of mating and 2 weeks after weaning. No observable changes in weight-specific or gross daily energy consumption was evident in the 3 weeks before the week in which birth occurred, although weights of females had by then increased an average of 36%. Gross daily energy consumption increased by 96%, 136%, and 194%, respectively, during the 1st, 2nd, and 3rd weeks after birth. Weights of females dropped significantly in the week before weaning.
Unmasking Intra-Tumoral Heterogeneity and Clonal Evolution in NF1-MPNST

Sarcomas are highly aggressive cancers that have a high propensity for metastasis, fail to respond to conventional therapies, and carry a poor 5-year survival rate. This is particularly true for patients with neurofibromatosis type 1 (NF1), in which 8%–13% of affected individuals will develop a malignant peripheral nerve sheath tumor (MPNST). Despite continued research, no effective therapies have emerged from recent clinical trials based on preclinical work. One explanation for these failures could be the lack of attention to intra-tumoral heterogeneity. Prior studies have relied on a single sample from these tumors, which may not be representative of all subclones present within the tumor. In the current study, samples were taken from three distinct areas within a single tumor from a patient with an NF1-MPNST. Whole exome sequencing, RNA sequencing, and copy number analysis were performed on each sample. A blood sample was obtained as a germline DNA control. Distinct mutational signatures were identified in different areas of the tumor as well as significant differences in gene expression among the spatially distinct areas, leading to an understanding of the clonal evolution within this patient. These data suggest that multi-regional sampling may be important for driver gene identification and biomarker development in the future.
GLYCOSYLTRANSFERASES IN OLIGOSACCHARIDE SYNTHESIS

Recent demonstrations that oligosaccharides play important roles in diverse biological events have resulted in renewed interest in the synthesis of oligosaccharides and their analogs. The availability of such molecules can facilitate studies on carbohydrate-protein recognition and help to elucidate molecular mechanisms of oligosaccharide-mediated biological processes that could eventually lead to rationally designed carbohydrate-based therapeutics. Despite many advances that have been made over the past decades, the chemical synthesis of oligosaccharides remains a challenge. This is attributed to the inherent chemical difficulties presented by this class of molecules. Each monosaccharide carries at least three hydroxyl groups that must be protected and deprotected during synthesis. Also, glycosylation generates a new stereocenter at the anomeric carbon, and there are no general methods for the introduction of all types of glycosidic linkage in a manner that is both stereo-controlled and high yielding. The chemical synthesis of oligosaccharides is therefore very timeconsuming and requires specialized expertise. The synthesis of oligosaccharide analogs containing modified sugars is an even more complex task than the preparation of natural structures. Almost twice as many steps are usually required for analog synthesis and the steps are more difficult, since most chemical protocols in the literature have been optimized for natural sugars. In nature, glycosyltransferase enzymes accomplish the ‘‘daunting’’ task of the construction of diverse and complex oligosaccharide. These enzymes catalyze
Circadian locomotor rhythm masked by the female reproduction cycle in cockroaches

Blattella bisignata (Brunner) and B. germanica (L.) are oviparous cockroaches with cyclic reproductive behaviour, but in B. germanica only males show circadian rhythmicity of locomotion at 28°C and DD (constant darkness). In B. bisignata, males and virgin females cockroaches entrained by light–dark cycles show free‐running rhythmicity in DD, and most activities occur during the subjective night. Daily locomotor activities of virgin females show cyclic changes that coincided with ovarian development. Virgin females also exhibit calling behaviour during the subjective night, and this shows a free‐running rhythm. Male mate‐finding locomotion and female calling behaviour are under circadian control, so the timing for both behaviours is synchronized. However, most mated females do not show a locomotor free‐running rhythm under DD conditions. Our results indicate that only mated females could not express a circadian locomotor rhythm. Pregnancy reduces a female’s locomotory intensity and masks the expression of a circadian locomotor rhythm. We attribute the differences in circadian locomotory rhythms between these two species to their living environments and mate‐finding strategies.
Reply to Manger’s Commentary on “A quantitative test of the thermogenesis hypothesis of cetacean brain evolution, using phylogenetic comparative methods”

In his Commentary (Manger PR. 2009. Subglacial cetaceans and other mathematical mysteries: a Commentary on “A quantitative test of the thermogenesis hypothesis of cetacean brain evolution, using phylogenetic comparative methods” by C. Maximino. Mar Fresh Behav Physiol. 42: 359–362) on my paper (Maximino C. 2009. A quantitative test of the thermogenesis hypothesis of cetacean brain evolution, using phylogenetic comparative methods. Mar Freshwater Behav Physiol. 42:1–17), Dr Paul Manger noted four errors in the quantitative analysis of the relationship between cetacean encephalization quotients (EQs) and water temperatures, which I suggested was a test of his thermogenesis hypothesis (Manger PR. 2006. An examination of cetacean brain structure with a novel hypothesis correlating thermogenesis to the evolution of a big brain. Biol Rev Camb Philos Soc. 81:293–338). These referred to incorrect raw data on water temperatures for two species, odd use of midpoint temperatures as independent variable, lack of inclusion of data on Mysticeti and the use of a differently derived EQ and midpoints instead of the EQs proposed by Manger and temperature ranges; Dr Manger proposed that these errors invalidate the analysis, with special emphasis in an observation that, since my paper did not address the relationship between EQs and temperature range, it did not actually test the thermogenesis hypothesis. In this Reply, I apologize for the mistakes which were made, and show that re-analysis using all the proposed alterations do not qualitatively or quantitatively alter the final result. I also argue that the relationship between phylogenetically correct EQs and midpoint temperatures is a better test of the thermogenesis hypothesis than the relationship between non-phylogenetic EQs and temperature ranges.
