Northern range expansion of the Asian tiger mosquito (Aedes albopictus): Analysis of mosquito data from Connecticut, USA

Background The Asian tiger mosquito (Aedes albopictus) is an invasive species and important arbovirus vector that was introduced into the U.S. in the 1980's where it continues to expand its range. Winter temperature is an important constraint to its northward expansion, with potential range limits located between the 0° and -5°C mean cold month isotherm. Connecticut is located within this climatic zone and therefore, Ae. albopictus was monitored statewide to assess its northern range expansion and to delineate where populations can stably persist. Methodology/Principal findings Ae. albopictus females were monitored at fixed trapping sites throughout Connecticut from June-October over a 20-year period, 1997–2016. In addition, Ae. albopictus larvae and pupae were collected from tire habitats and tires were retrieved from the field in the spring and flooded to evaluate overwintering success of hatching larvae. Ae. albopictus was first detected during statewide surveillance when a single adult female was collected in 2006. This species was not collected again until 2010 and was subsequently detected each successive year with increasing abundance and distribution except following the unusually cold winters of 2014 and 2015. Ae. albopictus mosquitoes were most abundant in urban and suburban locations along the southwestern shoreline of Connecticut; however, single specimens were occasionally detected in central parts of the state. Field-collected females were also screened for arbovirus infection yielding two isolations of Cache Valley virus and one isolation of West Nile virus, highlighting the threat posed by this mosquito. Ae. albopictus overwintered in Connecticut under mild winter conditions as shown by recovery of hatched larvae from field collected tires in spring and by early season detection of larvae and pupae. Conclusions/Significance This study documents the establishment and expansion of Ae. albopictus at the northern boundary of its range in the northeastern U.S. and provides a baseline for monitoring the future spread of this species anticipated under climate change.
Is participation contagious? Evidence from a household vector control campaign in urban Peru

Objectives High rates of household participation are critical to the success of door-to-door vector control campaigns. We used the Health Belief Model to assess determinants of participation, including neighbour participation as a cue to action, in a Chagas disease vector control campaign in Peru. Methods We evaluated clustering of participation among neighbours; estimated participation as a function of household infestation status, neighbourhood type and number of participating neighbours; and described the reported reasons for refusal to participate in a district of 2911 households. Results We observed significant clustering of participation along city blocks (p<0.0001). Participation was significantly higher for households in new versus established neighbourhoods, for infested households, and for households with more participating neighbours. The effect of neighbour participation was greater in new neighbourhoods. Conclusions Results support a ‘contagion’ model of participation, highlighting the possibility that one or two participating households can tip a block towards full participation. Future campaigns can leverage these findings by making participation more visible, by addressing stigma associated with spraying, and by employing group incentives to spray.
Fast semi-dense 3D semantic mapping with monocular visual SLAM

Fast 3D reconstruction with semantic information on road scenarios involves issues of geometry and appearance in the field of computer vision. An important idea is that fusion of geometry and appearance would boost the performance of each other. Stereo cameras and RGB-D sensors are widely used to realise 3D reconstruction and trajectory tracking, but they need heavy computation cost and storage in a dense way. Moreover, they lack flexibility of seamless switch between various scaled environments, i.e., indoor and outdoor scenes. Besides, autonomous vehicle would benefit from semantic information on the road, but it is hard to be sufficiently accurate and consistent in the 3D mapping. We address this challenge by fusion of direct Simultaneous Localisation and Mapping (SLAM) from a monocular camera in a semi-dense way and the state-of-the-art approaches of deep neural network. In our approach, 2D semantic information is transferred to 3D mapping via correspondence between consecutive Keyframes with spatial consistency. Since there are lots of semantic redundancies in consecutive frames, it is not necessary to process semantic segmentation for each frame in the entire sequence. Consequently, the segmentation could run in a reasonable speed (about 20Hz). We thoroughly evaluate our methods on road scene datasets. The experiments show a promising 3D semantic mapping in various road scenes.
A three-phase step-up DC-DC converter with a three-phase high frequency transformer

This paper presents a new 3-phase step-up DC-DC converter with a 3-phase high frequency isolation transformer. This converter was developed for industrial applications where the DC input voltage is lower than the output voltage, for instance in, installations fed by battery units, photovoltaic arrays or fuel cell systems. The converter's main characteristics are: reduced input ripple current, step-up voltage, high frequency isolating transformer, reduced output voltage ripple due to three pulsed output current and the presence of only three actives switches connected at the same reference, this being a main advantage of this converter. By means of a specific switch modulation, the converter allows two operational regions. Theoretical expressions and experimental results are presented for a 6.8 kW prototype, operating in region R2 and for a 3.4 kW prototype operating in region R3, both in continuous conduction mode.
A Prospective Randomized Controlled Trial to Study the Impact of a Nutrition-Sensitive Intervention on Adult Women With Cancer Cachexia Undergoing Palliative Care in India

Purpose. Advanced cancer patients with disease progression develop cachexia. Nevertheless, cancer patients at nutritional risk have shown improved body weight and quality of life with oral nutritional supplements. Method. This was a randomized controlled trial in adult female cancer patients (n = 63) attending palliative clinics, with symptoms of cachexia. Eligible patients were randomly distributed into control (n = 33) and intervention (n = 30) groups. Both groups were provided with nutritional and physical activity counseling, but the intervention group received an additional 100 g of Improved Atta (IAtta) for 6 months daily consumption. This study was designed to assess the efficacy of IAtta (with counseling) in enhancing the health status of cachexic patients. Anthropometric measurements, dietary intake, physical activity level and quality of life parameters were assessed at baseline, after 3 months, and at the end of 6 months. Results. Patients in the control group (n = 15) had significantly decreased body weight (P = .003), mid–upper-arm circumference (P = .002), and body fat (P = .002) by the end of intervention. A trend of body weight gain in the intervention group (n = 17; P = .08) and significant increase of body fat (P = .002) was observed; moreover, patients reported a significant improvement in fatigue (P = .002) and appetite scores (P = .006) under quality-of-life domains at the end of intervention. Conclusions. Embedding a nutrition-sensitive intervention ( IAtta ) within Indian palliative care therapy may improve quality of life and stabilize body weight in cancer cachexia patients.
Prenatal Risk and Infant Regulation: Indirect Pathways via Fetal Growth and Maternal Prenatal Stress and Anger.

Pathways from maternal tobacco, marijuana, stress, and anger in pregnancy to infant reactivity and regulation (RR) at 9 months of infant age were examined in a low-income, diverse sample beginning in the first trimester of pregnancy, with fetal growth and postnatal stress/anger as potential mediators, and infant sex as a moderator. Participants were 247 dyads (173 substance-exposed infants). There were no direct effects of prenatal risk on RR and no moderation by sex. However, there were significant indirect effects on RR via poor fetal growth and higher postnatal anger. The study adds to the sparse literature on joint effects of tobacco and marijuana, and highlights the role of fetal growth and maternal anger as important pathways from prenatal risk to infant RR.
Comparison of Visually Guided Flight in Insects and Birds

Over the last half century, work with flies, bees, and moths have revealed a number of visual guidance strategies for controlling different aspects of flight. Some algorithms, such as the use of pattern velocity in forward flight, are employed by all insects studied so far, and are used to control multiple flight tasks such as regulation of speed, measurement of distance, and positioning through narrow passages. Although much attention has been devoted to long-range navigation and homing in birds, until recently, very little was known about how birds control flight in a moment-to-moment fashion. A bird that flies rapidly through dense foliage to land on a branch—as birds often do—engages in a veritable three-dimensional slalom, in which it has to continually dodge branches and leaves, and find, and possibly even plan a collision-free path to the goal in real time. Each mode of flight from take-off to goal could potentially involve a different visual guidance algorithm. Here, we briefly review strategies for visual guidance of flight in insects, synthesize recent work from short-range visual guidance in birds, and offer a general comparison between the two groups of organisms.
The Functions of Grainy Head-Like Proteins in Animals and Fungi and the Evolution of Apical Extracellular Barriers

The Grainy head (GRH) family of transcription factors are crucial for the development and repair of epidermal barriers in all animals in which they have been studied. This is a high-level functional conservation, as the known structural and enzymatic genes regulated by GRH proteins differ between species depending on the type of epidermal barrier being formed. Interestingly, members of the CP2 superfamily of transcription factors, which encompasses the GRH and LSF families in animals, are also found in fungi – organisms that lack epidermal tissues. To shed light on CP2 protein function in fungi, we characterized a Neurospora crassa mutant lacking the CP2 member we refer to as grainy head-like (grhl). We show that Neurospora GRHL has a DNA-binding specificity similar to that of animal GRH proteins and dissimilar to that of animal LSF proteins. Neurospora grhl mutants are defective in conidial-spore dispersal due to an inability to remodel the cell wall, and we show that grhl mutants and the long-known conidial separation-2 (csp-2) mutants are allelic. We then characterized the transcriptomes of both Neurospora grhl mutants and Drosophila grh mutant embryos to look for similarities in the affected genes. Neurospora grhl appears to play a role in the development and remodeling of the cell wall, as well as in the activation of genes involved in defense and virulence. Drosophila GRH is required to activate the expression of many genes involved in cuticular/epidermal-barrier formation. We also present evidence that GRH plays a role in adult antimicrobial defense. These results, along with previous studies of animal GRH proteins, suggest the fascinating possibility that the apical extracellular barriers of some animals and fungi might share an evolutionary connection, and that the formation of physical barriers in the last common ancestor was under the control of a transcriptional code that included GRH-like proteins.
Structural outcomes in the Cleft Care UK study. Part 2: dento-facial outcomes

Structured Abstract Objectives To compare facial appearance and dento-alveolar relationship outcomes from the CSAG (1998) and CCUK (2013) studies. Setting and sample population Five-year-olds born with non-syndromic unilateral cleft lip and palate. Those in the original CSAG were treated in a dispersed model of care with low-volume operators. Those in CCUK were treated in a more centralized, high-volume operator model. Materials and methods We compared facial appearance using frontal view photographs (252 CCUK, 239 CSAG) and dental relationships using study models (198 CCUK, 223 CSAG). Facial appearance was scored by a panel of six assessors using a standardized and validated outcome tool. Dento-alveolar relationships were scored by two assessors using the 5-Year-Olds’ Index. Ordinal regression was used to compare results between surveys. Results Excellent or good facial appearance was seen in 36.2% of CCUK compared with 31.9% in CSAG. In CCUK, 21.6% were rated as having poor or very poor facial appearance compared with 27.6% in CSAG. The percentage rated as having excellent or good dento-alveolar relationships was 53.0% in CCUK compared with 29.6% in CSAG. In CCUK, 19.2% were rated as having poor or very poor dento-alveolar relationships compared to 36.3% in CSAG. The odds ratios for improved outcome in CCUK compared to CSAG were 1.43 (95% CI 1.03, 1.97) for facial appearance and 2.29 (95% CI 1.47, 3.55) for dento-alveolar relationships. Conclusions Facial and dento-alveolar outcomes were better in CCUK children compared to those in CSAG.
POm Thalamocortical Input Drives Layer-Specific Microcircuits in Somatosensory Cortex

Higher-order thalamic nuclei, such as the posterior medial nucleus (POm) in the somatosensory system or the pulvinar in the visual system, densely innervate the cortex and can influence perception and plasticity. To systematically evaluate how higher-order thalamic nuclei can drive cortical circuits, we investigated cell-type selective responses to POm stimulation in mouse primary somatosensory (barrel) cortex, using genetically targeted whole-cell recordings in acute brain slices. We find that ChR2-evoked thalamic input selectively targets specific cell types in the neocortex, revealing layer-specific modules for the summation and processing of POm input. Evoked activity in pyramidal neurons from deep layers is fast and synchronized by rapid feedforward inhibition from GABAergic parvalbumin-expressing neurons, and activity in superficial layers is weaker and prolonged, facilitated by slow inhibition from GABAergic neurons expressing the 5HT3a receptor. Somatostatin-expressing GABAergic neurons do not receive direct input in either layer and their spontaneous activity is suppressed during POm stimulation. This novel pattern of weak, delayed, thalamus-evoked inhibition in layer 2 suggests a longer integration window for incoming sensory information and may facilitate stimulus detection and plasticity in superficial pyramidal neurons.
Comparison of three data mining models for prediction of advanced schistosomiasis prognosis in the Hubei province

Background In order to better assist medical professionals, this study aimed to develop and compare the performance of three models—a multivariate logistic regression (LR) model, an artificial neural network (ANN) model, and a decision tree (DT) model—to predict the prognosis of patients with advanced schistosomiasis residing in the Hubei province. Methodology/Principal findings Schistosomiasis surveillance data were collected from a previous study based on a Hubei population sample including 4136 advanced schistosomiasis cases. The predictive models use LR, ANN, and DT methods. From each of the three groups, 70% of the cases (2896 cases) were used as training data for the predictive models. The remaining 30% of the cases (1240 cases) were used as validation groups for performance comparisons between the three models. Prediction performance was evaluated using area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy. Univariate analysis indicated that 16 risk factors were significantly associated with a patient’s outcome of prognosis. In the training group, the mean AUC was 0.8276 for LR, 0.9267 for ANN, and 0.8229 for DT. In the validation group, the mean AUC was 0.8349 for LR, 0.8318 for ANN, and 0.8148 for DT. The three models yielded similar results in terms of accuracy, sensitivity, and specificity. Conclusions/Significance Predictive models for advanced schistosomiasis prognosis, respectively using LR, ANN and DT models were proved to be effective approaches based on our dataset. The ANN model outperformed the LR and DT models in terms of AUC.
Decrease in Histidine-Rich Glycoprotein as a Novel Biomarker to Predict Sepsis Among Systemic Inflammatory Response Syndrome

Objectives: Many biomarkers for sepsis are used in clinical practice; however, few have become the standard. We measured plasma histidine-rich glycoprotein levels in patients with systemic inflammatory response syndrome. We compared histidine-rich glycoprotein, procalcitonin, and presepsin levels to assess their significance as biomarkers. Design: Single-center, prospective, observational cohort study. Setting: ICU at an university-affiliated hospital. Patients: Seventy-nine ICU patients (70 with systemic inflammatory response syndrome and 9 without systemic inflammatory response syndrome) and 16 healthy volunteers. Interventions: None. Measurements and Main Results: We collected blood samples from patients within 24 hours of ICU admission. Histidine-rich glycoprotein levels were determined using enzyme-linked immunosorbent assay. The median histidine-rich glycoprotein level in healthy volunteers (n = 16) was 63.00 µg/mL (interquartile range, 51.53–66.21 µg/mL). Histidine-rich glycoprotein levels in systemic inflammatory response syndrome patients (n = 70; 28.72 µg/mL [15.74–41.46 µg/mL]) were lower than those in nonsystemic inflammatory response syndrome patients (n = 9; 38.64 µg/mL [30.26–51.81 µg/mL]; p = 0.049). Of 70 patients with systemic inflammatory response syndrome, 20 had sepsis. Histidine-rich glycoprotein levels were lower in septic patients than in noninfective systemic inflammatory response syndrome patients (8.71 µg/mL [6.72–15.74 µg/mL] vs 33.27 µg/mL [26.57–44.99 µg/mL]; p < 0.001) and were lower in nonsurvivors (n = 8) than in survivors (n = 62) of systemic inflammatory response syndrome (9.06 µg/mL [4.49–15.70 µg/mL] vs 31.78 µg/mL [18.57–42.11 µg/mL]; p < 0.001). Histidine-rich glycoprotein showed a high sensitivity and specificity for diagnosing sepsis. Receiver operating characteristic curve analysis for detecting sepsis within systemic inflammatory response syndrome patients showed that the area under the curve for histidine-rich glycoprotein, procalcitonin, and presepsin was 0.97, 0.82, and 0.77, respectively. In addition, survival analysis in systemic inflammatory response syndrome patients revealed that the Harrell C-index for histidine-rich glycoprotein, procalcitonin, and presepsin was 0.85, 0.65, and 0.87, respectively. Conclusions: Histidine-rich glycoprotein levels were low in patients with sepsis and were significantly related to mortality in systemic inflammatory response syndrome population. Furthermore, as a biomarker, histidine-rich glycoprotein may be superior to procalcitonin and presepsin.
Discrepancy between social and nonsocial decision-making under uncertainty following prefrontal lobe damage: the impact of an interactionist approach

ABSTRACT Deficits in decision-making are thought to contribute significantly to socio-behavioral impairments of patients with frontal lobe damage. The purpose of this study was to test the hypothesis of whether the inappropriate social behavior of patients with frontal lesions can be viewed as the product of a general failure of decision-making ability or as the result of socio-cognitive impairment. We studied a group of patients with prefrontal lesions (FL patients, n = 15) and a group of matched healthy controls (n = 30) on the Iowa Gambling task (IGT) of nonsocial decision-making, environmental dependency phenomena (EDP) during social interaction, and the “reading the mind in the eyes” and “character intention task” of theory of mind (TOM) tasks. The FL patients were impaired in both TOM and EDP protocols but, surprisingly, they behaved appropriately in the IGT. In addition, FL patients with EDP did not differ in executive functioning, IGT and TOM measures from those who did not demonstrate these behavioral disorders. The right orbitofrontal cortex was associated with social decision-making deficits. By adopting an interactionist approach, this study raises the possibility of identifying components of social and nonsocial decision-making, which could be helpful in understanding the behavioral disorders of FL patients.
Outpatient visits for infectious diseases in the United States, 1980 through 1996.

BACKGROUND Recent studies have documented increases in infectious disease mortality and in the proportion of hospitalizations attributable to infectious diseases. To further evaluate trends in the burden of infectious diseases in the United States, we analyzed data from the National Ambulatory Medical Care Survey from 1980 through 1996. OBJECTIVE To examine the epidemiology of and recent trends in outpatient visits for infectious diseases. METHODS Data were from a national probability sample of patient visits to office-based physicians. Diagnoses reported by the surveyed physicians were coded to indicate whether they were infectious or noninfectious. Infectious diseases were placed into 11 mutually exclusive categories. RESULTS During the course of the survey, infectious diseases accounted for 19.0% of visits to physicians, or an average of 129 million visits per year. The infectious disease visit rate was higher in females than in males (587 vs 461 per 1000 persons per year) and higher in non-Hispanic whites than in non-Hispanic blacks or Hispanics (538 vs 407 vs 485 per 1000 persons per year). The visit rate for infectious diseases was greatest in 0- to 4-year-olds. Upper respiratory tract infections accounted for the largest proportion of visits (38.0% of infectious disease visits), followed by otitis (15.1%) and lower respiratory tract infections (14.1%). The age-adjusted visit rate for infectious diseases increased from 462 visits per 1000 persons (17.5% of all visits) in 1980 to 575 (20.2%) in 1990. From 1990 to 1996, this rate declined to 483 per 1000 (18.1%). CONCLUSIONS Infectious diseases are responsible for a substantial proportion of outpatient visits to physicians in the United States. Upper respiratory tract infections account for the largest proportion of these visits.
Biological identification of springtails (Hexapoda: Collembola) from the Canadian Arctic, using mitochondrial DNA barcodes

We evaluated sequence diversity in the mitochondrial cytochrome-c oxidase I (COI; EC 1.9.3.1) gene as a tool for resolving differences among species of Arctic springtails. The Collembola examined in this analysis were collected from Igloolik, Cornwallis, and Somerset islands and included representatives from all major families found in the Arctic. Members of 13 genera and 19 species were examined, including 4 species of the genus Folsomia and 3 species of the genus Hypogastrura. In all cases, species were successfully discriminated. Sequence divergences within species were generally less than 1%, whereas divergences between species were greater than 8% in all cases. Divergences among individuals of one species of Folsomia were much higher (up to 13%), but this likely represents the presence of an undescribed sibling species. We conclude that DNA barcoding is a powerful tool for identifying species of Collembola and should regularly be useful as a complement to traditional, morphological taxonomy.
