Interspecific competition leads to more long‐winged morphs in two sympatric cricket species

Abstract Coexistence mechanisms for species competing for the same resource include resource partitioning, neutrality, microhabitat preference and trade‐off between competitive and dispersal abilities. We explored the coexistence mechanism of two species of trigonidiid crickets (Dianemobius nigrofasciatus (Orthoptera: Trigonidiidae) and Polionemobius taprobanensis (Orthoptera: Trigonidiidae)) that share the same habitat. Dianemobius nigrofasciatus is more common in areas where the ground surface is somewhat open, while P. taprobanensis is more common in more densely vegetated environments. The effects of micro‐environmental differences, similarities in competitive ability and investment in dispersal ability under interspecific competitive conditions on the coexistence of these species were examined using laboratory experiments. Both P. taprobanensis and D. nigrofasciatus performed better in vegetated environments. Although the adult emergence of D. nigrofasciatus were delayed by the presence of P. taprobanensis, the emergence rate of P. taprobanensis was not significantly affected by D. nigrofasciatus. The presence of P. taprobanensis caused a higher frequency of a long‐winged morph (macropterous) of D. nigrofasciatus. The results suggest that D. nigrofasciatus is inferior to P. taprobanensis in interspecific competition, and it, therefore, disperses (as macropterous adults) at greater rates in the presence of P. taprobanensis. Furthermore, it may be that D. nigrofasciatus has been forced to change its preferred microhabitat from vegetative habitats, which are inherently more suitable, to more open environments due to competition. These above mechanisms are thought to allow the two species to coexist in the same habitat.

A novel genetic mouse model of osteoporosis with double heterozygosity of Irx3 and Irx5 characterizes sex-dependent phenotypes in bone homeostasis

Iroquois homeobox gene 3 (Irx3) and Irx5 encode transcription factors that play crucial roles in limb development and bone formation. Previous studies using knockout mice have revealed a role of Irx3 and Irx5 in osteogenesis in young adult mice. However, whether these genes are also essential for bone homeostasis in adulthood and contribute to bone diseases remain poorly understood. Osteoporosis is a disease characterized by lower bone mineral density and disrupted bone microarchitecture, typically occurs in postmenopausal women. Here, we demonstrate that Irx3/5dHet mice with a half-reduction of Irx3 and Irx5 dosage serve as a novel model of osteoporosis. By micro-computed tomography, we found that Irx3/5dHet mice exhibited sex-dependent bone loss patterns. While male Irx3/5dHet mice progressively lost trabecular microstructures with aging, female mutants exhibited lower bone mineral density (BMD) and bone volume fraction (BV/TV) at early adulthood (9–15 weeks old) but without further loss later at 1 year of age. Bone marrow adipocytes are known to be elevated at the expenses of lower osteogenesis in osteoporotic bone marrow. Surprisingly, we found sex-dependent changes in adipogenesis at the age of skeletal maturity that bone marrow adipocytes were reduced in female Irx3/5dHet mice along with deteriorated osteogenesis, while male mice exhibited elevated adipogenesis. In summary, we reported a novel genetic model for osteoporosis-like phenotypes, highlighting sex-dependent bone mineral density and bone marrow adipocyte characteristics.

A Study of the Neurobiological Mechanisms of Non-suicidal Self-injurious Behaviour

Non-suicidal self-injury (NSSI) often occurs in adolescence and early adulthood, accompanied by an increase in the incidence and development of related diseases, making it a significant risk factor for suicide. NSSI behavior among adolescents has become a serious public health issue, threatening their physical and mental development. This article explores the identification methods, biological causes, and emotional causes of NSSI behavior and provides current applicable treatment interventions. By elaborating on the harm of NSSI behavior to adolescents, identification methods, and intervention strategies are proposed to provide a theoretical basis for monitoring and protecting adolescent health in order to improve NSSI behavior among adolescents.

Development and implementation of autoverification standardization in the adult and pediatric emergency department.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. This project utilized the guidance of the American Society of Health-System Pharmacists (ASHP) autoverification toolkit to refine our health system's approach to autoverification and contribute to the literature regarding appropriate use of autoverification technology in a pediatric and adult emergency department (ED). This single-center quality improvement study was conducted in an academic medical center ED that has 33 pediatric beds and 77 adult beds. A team consisting of clinical pharmacy specialists in emergency medicine, medication safety and informatics personnel, operational managers, and pharmacy leadership was identified to develop and implement autoverification best practices in the ED utilizing practices outlined within the ASHP autoverification toolkit. Before implementation of best practices, defined as the "preoptimization" state, autoverification took place for most medications available in the automated dispensing cabinets (ADCs). By anchoring the autoverification rule on ADC inventory, it was challenging to optimize both inventory practices and autoverification best practices. This project focused on redesigning the autoverification rules in the electronic health record, defined as the "postoptimization" state. In the postoptimization state, autoverification in the ED was updated to better align with regulatory standards. Autoverification metrics and the percentage of orders that autoverified vs required pharmacist verification were analyzed in the preoptimization and postoptimization states. This project utilized the guidance from ASHP's autoverification toolkit to refine our health system's approach to autoverification. High-alert medications (eg, insulin, extended-release opioids, digoxin) were taken off autoverification following implementation. Optimization of autoverification rules allows more orders for high-alert medications to be reviewed by a pharmacist.

Subjective well-being in early adulthood—long-term consequences of inclusive vs. segregated education for students with special educational needs in Germany?

ABSTRACT We analysed the long-term consequences of inclusive versus segregated educational settings for students with special educational needs in the area of learning (SEN-L, formerly ‘learning disability”) in Germany. We focused on the consequences of educational settings on subjective well-being (SWB) measured as general life satisfaction five to six years after leaving a mainstream or a special school. We accounted for the selection of students into the different educational settings based on a variety of individual and socio-demographic characteristics. To this end, we conducted entropy balancing and controlled for the current status of not being in education, employment or training (NEET). Young adults who formerly attended segregated special schools reported on average slightly lower levels of life satisfaction. They were also at a much higher risk of being excluded from post-secondary education and the labour market at the age of 20 to 21. However, the differences in life satisfaction were not significant when accounting for systematic differences in individual and socio-demographic characteristics between the two groups. This finding highlights the importance of considering the selection mechanisms underlying educational settings in analyses of outcomes of students with SEN. Their current NEET status did not explain differences in life satisfaction by educational setting.

The association of resilience with HbA1c and key psychosocial factors in emerging adults with type 1 diabetes.

Emerging adults (EAs) with type 1 diabetes (T1D) have difficulty meeting glycemic targets and have a high prevalence of mental health comorbidities. Resilience, the ability to harness resources needed to sustain one's emotional and physical well-being, may be a key factor impacting poor mental health and glycemic outcomes. We aimed to (a) evaluate the association between resilience, HbA1c, and key psychosocial factors and (b) explore whether resilience moderates the relationship between psychosocial factors (depression, diabetes-related distress, anxiety) and HbA1c in EAs with T1D. EAs with T1D (N = 233) (mean age = 19.9 years (SD = 1.6), range 16.8-24.7) seen at an EA-specific diabetes clinic completed resilience, diabetes-related distress, depression, and anxiety measures and had their HbA1c level evaluated. We used linear regression models and conducted moderation analyses for the resilience factor. Resilience was strongly associated with HbA1c, depression, diabetes-related distress, and anxiety in EAs with T1D. We did not find evidence that resilience moderates the relationship between depression, anxiety, or diabetes-related distress and HbA1c. This study found that resilience is a highly relevant psychological factor associated with HbA1c and a key mental health factor for EAs with T1D. Novel interventions are needed to ameliorate high diabetes-related distress and HbA1c, and bolstering resilience may be one avenue to explore. Future research on resilience should longitudinally characterize and evaluate whether resilience may be a mechanism underlying the relationship between poor psychosocial outcomes and not meeting glycemic targets in EAs with T1D.

Early mortality in STXBP1-related disorders.

Pathogenic variants in STXBP1 cause a spectrum of disorders mainly consisting of developmental and epileptic encephalopathy (DEE), often featuring drug-resistant epilepsy. An increased mortality risk occurs in individuals with drug-resistant epilepsy and DEE, with sudden unexpected death in epilepsy (SUDEP) often the major cause of death. This study aimed to identify the rate and causes of mortality in STXBP1-related disorders. Through an international call, we analyzed data on individuals with STXBP1 pathogenic variants, who passed away from causes related to their disease. We estimated a mortality rate of 3.2% (31/966), based on the STXBP1 Foundation and the STXBP1 Global Connect registry. In total, we analyzed data on 40 individuals (23 males) harboring pathogenic STXBP1 variants, collected from different centers worldwide. They died at a median age of 13years (range: 11months-46years). The most common cause of death was SUDEP (36%), followed by pulmonary infections and respiratory complications (33%). The incidence of SUDEP peaked in mid-childhood, while non-SUDEP causes were more frequent in early childhood or adulthood (p = 0.006). In the most severe phenotypes, death was related to non-SUDEP causes (p = 0.018). We found a mortality rate in STXBP1-related disorders similar to other DEEs, with an early age at death and SUDEP as well as pulmonary infections as the main cause of death. These findings assist in prognostic evaluation and genetic counseling for the families. They help to define the mortality risk of STXBP1-related disorders and implement preventative strategies.

A Randomized Controlled Trial of a Digital Intervention to Improve the Sexual Health of Adolescent and Young Adult Male Emergency Department Patients

PurposeTo assess implementation outcomes and potential efficacy of a user-informed, theory-based digital health intervention developed to improve adolescent and young adult (AYA) male sexual health. MethodsWe conducted a pilot randomized controlled trial of sexually active male emergency department (ED) patients aged 14–21 years. Participants were randomized to the intervention (Dr. Eric, Emergency Room Interventions to improve Care) or usual care. Dr. Eric consists of an ED-based sexual health app followed by 3 months of interactive text messages. We assessed the feasibility, adoption, and fidelity among users. Condom use, defined as the number of sexual encounters with condoms divided by the total number of sexual encounters over the past 4 weeks, was the primary efficacy outcome. ResultsWe enrolled 119 patients; mean age was 17.9 years, 87% were Hispanic, and half used condoms at last intercourse. Dr. Eric demonstrated feasibility, with high rates of consent (86.2%) and follow-up (81.5%). Intervention participants found Dr. Eric acceptable, liking (86.2%) and recommending (87.9%) the program. 98% of intervention participants interacted with all five app modules; one-quarter opted out of text messaging. At 6-week follow-up, the intervention group more often used a condom compared to the control group [OR 3.57, 95% confidence interval (1.93, 6.60)], p < .001]; however, this significant difference did not sustain at 13 weeks. DiscussionDr. Eric was feasible to deliver and acceptable to male AYA patients. To our knowledge, Dr. Eric is the first intervention to demonstrate evidence of short-term efficacy for improving condom use among male AYA in the ED.

Predictability of adult patient medical emergency condition from triage vital signs and comorbidities: a single-center, observational study

BackgroundVital signs and comorbid diseases are the first information evaluated in patients admitted to the emergency department (ED). In most EDs, triage of patients takes place with vital signs and admission complaints only. Comorbidities are generally underestimated when determining the patient’s status at the triage area. This study aims to assess the relationship between initial vital signs, comorbid diseases, and medical emergency conditions (MEC) in patients admitted to the ED.MethodsThis prospective study was designed as a single-center observational study, including patients admitted to a tertiary ED between 16.06.2022 and 09.09.2022. Patients younger than 18, readmitted to the ED within 24 h, or absence of vital signs due to cardiac arrest were excluded from the study. Vital signs and comorbid diseases of all patients were recorded. The mortality within 24 h, the need for intensive care unit admission, emergency surgery, and life-saving procedures were considered “medical emergency conditions”. The role of vital signs and comorbid diseases in predicting emergencies was analyzed by binary logistic regression.ResultsA total of 10,022 patients were included in the study; 5056 (50.4%) were female, and 4966 (49.6%) were male. Six hundred four patients presented with an MEC. All vital signs -except diastolic hypertension and tachycardia- and comorbidities were found statistically significant. Hypoxia (Odd’s Ratio [OR]: 1.73), diastolic hypotension (OR: 3.71), tachypnea (OR: 8.09), and tachycardia (OR: 1.61) were associated with MECs. Hemiplegia (OR: 5.7), leukemia (OR: 4.23), and moderate-severe liver disease (OR: 2.99) were the most associated comorbidities with MECs. In our study, an MEC was detected in 3.6% (186 patients) of the patients with no abnormal vital signs and without any comorbidities.ConclusionAmong the vital signs, hypoxia, diastolic hypotension, tachypnea, and tachycardia should be considered indicators of an MEC. Hemiplegia, leukemia, and moderate-severe liver disease are the most relevant comorbidities that may accompany the MECs.

Intermittent theta burst stimulation in adolescents and young adults with depressive disorders: protocol of a randomized, sham-controlled study with a sequential Bayesian design for adaptive trials.

Intermittent theta burst stimulation (iTBS), a variant of repetitive transcranial magnetic stimulation (rTMS), is an established treatment for adults with major depressive disorder (MDD). Due to its favorable safety profile, iTBS is also a promising early intervention in the transition phase from adolescence to early adulthood, but thishas not been systematically investigated to date. Thus, the EARLY-BURST trial investigates the efficacy and safety of iTBS over the left dorsolateral prefrontal cortex (lDLPFC) in treatment-seeking young patients (age 16-26years) with depressive disorders (i.e. major depressive disorder, persistent depressive disorder, bipolar depression), allowing for relevant co-morbidities. Participants have not received antidepressant or antipsychotic medication during the last 12months except for short-term (< 2weeks) on-demand medication. The trial will employ a novel sequential Bayesian, randomized, double-blind, parallel-group, sham-controlled design. Up to 90 patients at two clinical sites (Munich, Augsburg) will be randomized 1:1 to the treatment groups, with sequential analyses starting after 26 patients in each group completed the treatment. The primary outcome will be the difference in depression severity at week 6 (post-treatment visit) between active iTBS and sham iTBS, assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS). The trial is planned to be expanded towards a three-arm leapfrog design, contingent on securing additional funding. Thus, in addition to potentially providing evidence of iTBS's efficacy in adolescents and young adults with depressive disorders, the EARLY-BURST trial aims at setting the stage for subsequent platform trials in this dynamic research field, where novel adaptive study designs are required to meet the need for rapidly testing promising new vs established rTMS protocols.Trial registration: DRKS00033313.

A participatory research to assess how a student citizens’ assembly can facilitate the co-creation of nutrition interventions in higher education settings

BackgroundThe transition period from adolescence to early adulthood is critical for developing new nutritional behaviors, making higher education students an important target group for public health nutrition interventions. Given the complexity of nutrition-related behaviors and their various determinants, involving the student population (the future beneficiaries of interventions) and the partners engaged in their implementation when designing campus nutrition interventions is essential. Citizens’ assemblies are deliberative processes which are more and more frequently organized to co-create solutions to complex problems. This study aims 1) to design and implement a student citizens’ assembly using participatory research methods, 2) to describe its process and evaluate its transferability, 3) to evaluate changes in dietary habits, knowledge and citizen practices among students participating in this assembly.MethodsThis study will take place at a French university (University Sorbonne Paris Nord, USPN) located in socio-economically disadvantaged suburbs of Paris. The student citizens’ assembly will gather a mini-public of 30 students enrolled at the time of the study and a co-creation team of academic and non-academic partners involved in student life, nutrition, physical activity, or public policies. The aim of the assembly is to co-create a set of concrete proposals that would enhance USPN students’ access to sustainable diets and physical activity. The protocol is based on a continuous process evaluation and a pre-post design among the mini-public. A mixed-method framework combining quantitative and qualitative approaches will be developed. This study will make use of (i) field observations of the intervention process and transferability, (ii) data collected by questionnaires on pre- and post- dietary habits, knowledge and citizen practices of the mini-public, and (iii) pre-post interviews with a subsample of the same mini-public.DiscussionRelying on participatory research methods, this study will provide new insights into involving higher education students and diverse partners in co-creating campus nutrition interventions. Through the collaborative work of researchers, higher education students, university representatives, public institutions, and local and community actors, this study will provide evidence-based guidance for designing innovative and contextually-relevant nutrition interventions in the higher education setting.Trial registrationThis research was registered at the ClinicalTrial.gov (NCT06580795; registration date: 2024–08-30; https://www.clinicaltrials.gov/study/NCT06580795).

Developmental regulation processes and age-related motivation of distance education students

AbstractThe rise of technological advancements and the pandemic have made distance education increasingly prevalent, demanding high levels of self-regulation. This research addresses the integration of three core developmental regulation models of lifespan development and the motivators proposed by self-determination theory. Although regulation models are widely used in organizational contexts, their application in education is limited. Action regulation strategies and motivation are essential for student success across the lifespan. Age diversity can also influence students’ responses to these demands. Thus, this study aimed to gain insights into regulatory processes (meta-regulation, goal engagement, and disengagement) and motivation (internal and external) in undergraduate distance-learning students of psychology. Three hundred thirty-eight students (74.9% females) from different developmental stages of emerging adulthood, early adulthood, and middle adulthood participated in an online survey (aged 18–58 years; M = 30.80, SD = 10.18). Results revealed that middle-aged students scored higher on internal motivation compared to those in emerging and early adulthood. Conversely, the emerging adult group reported higher external motivation. Canonical correlation analysis (CCA) indicated higher levels of relentlessly pursuing goals in conjunction with meta-regulation might enhance the internal motivation of distance education students across various developmental stages. This study extends developmental regulation models to (distance) education, highlighting the significant relationship between internal and external motivation. It underscores the importance of developmental regulation and motivation for students from various backgrounds. Given the growing prevalence of distance education, the study discusses implications for supporting positive outcomes for distance learners.

Death, flies and environments: Towards a qualitative assessment of insect (Diptera) colonization of human cadavers retrieved from sites of death in Brazil

Empirical data on decomposition ecology have long established blowflies (Calliphoridae) and flesh flies (Sarcophagidae) (Diptera) as the most frequent colonizers of carrion, especially at early stages of decomposition. However, the scarcity of studies based on human cadavers has hindered inferences about colonization of homicide victims in real case scenarios. We describe here a survey of insects associated with cadavers retrieved from the site of death in Northeastern Brazil, with emphasis on the association between species diversity and the surrounding environment. We examined 81 cadavers, most of which were of men and resulting from violent death. Twelve cadavers (14.8 %) contained insect larvae, which were reared in the laboratory until adult emergence and identification. Ten species of Diptera effectively colonized the cadavers; seven of Family Calliphoridae – Chrysomya albiceps (Wiedemann, 1819), Chrysomya megacephala (Fabricius, 1794), Chrysomya putoria (Wiedemann, 1830), Cochliomyia macellaria (Fabricius, 1775), Hemilucilia segmentaria (Fabricius, 1805), Lucilia cuprina (Wiedemann, 1830), Lucilia eximia (Wiedemann, 1819) and three of Family Sarcophagidae, Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907), Microcerella halli (Engel, 1931) and Peckia (Sarcodexia) lambens (Wiedemann, 1830). The species C. albiceps and C. macellaria were the most frequent colonizers, while Sarcophagidae was reported in only four cases. Insects were present on cadavers found in urban (n = 8) and rural (n = 4) sites, outdoors (n = 6) and inside (n = 6) residences. Presence of larvae was more frequent in the natural orifices in the head (n = 11). Clothing did not prevent from ovi/larviposition for most species. We present the first register of B. stallengi colonizing human corpses and expand the knowledge on the geographical distribution of necrophagous insects. Our protocol may contribute to forensic entomology in areas exposed to fast decomposition, such as the Neotropical Region.

Adaptation and carry over effects of extreme sporadic heat stress in Culex mosquitoes

Mosquitoes, as temperature-sensitive ectothermic vectors, exhibit temperature-dependence. This study investigates Culex pipiens pallens (Cx. pallens) responses to abrupt temperature increases and their implications on mosquito physiology.First instar larvae (24hr post hatching) and newly enclosed adults (24hr post emergence) were separately exposed to heat shock regimes of 33 °C, 37 °C, and 42 °C for 3 days alongside a control temperature of 27 °C. Results showed that mortality was triggered at 42 °C within a day. Adult male mosquitoes were less tolerant to all temperatures than larvae and adult females (p < 0.05). Exposing larvae to constant temperatures for 3 days significantly decreased larvae's development time, growth rate and adult emergence (p < 0.05). Reproductive fitness was significantly reduced (p < 0.05) in males emerging from larvae exposed to 37 °C. Life table parameters showed significant increased mortality rate, kill power and decreased life expectancy at the embryonic stage (p < 0.05). Furthermore, heatwaves deactivated the Transient receptor protein ankyrin 1 at 37 °C (p < 0.05) in larvae but not adults. Calmodium, Heat shock protein 90, and small heat shock protein expression were significantly decreased in larvae at 37 °C (p < 0.05) as compared to larvae raised at 33 °C and 27 °C.In conclusion, we classified the heat waves into three categories: adaptable (33 °C), critical (37 °C), and fatal (42 °C). Prolonged exposure of Culex pallens larvae to extreme heat affects the male reproductive output. These findings may serve as an important reference for forecasting vector and pest dynamics and used to tailor mosquito prevention and control measures.

The impact of lethal and sub-lethal exposure of emamectin benzoate on populations of Spodoptera litura (Lepidoptera: Noctuidae) under laboratory conditions

Emamectin benzoate is an avermectin bio-insecticide commonly used for managing several insect pests including Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), a major polyphagous pest of many cultivated crops. The current study was conducted to evaluate the effects of emamectin benzoate on the fitness of S. litura populations exhibiting differential susceptibility to insecticide. The selection process and all the bioassays were carried out using 6-day-old 2nd instar larvae of S. litura. A field-collected population of S. litura was divided into two groups: one selected with emamectin benzoate for eight generations (EB-Sel) and the other kept unexposed (Unsel-Lab) to insecticide in the laboratory. An increase in resistance ratio from 1.71-fold in the F1 generation to 22.54-fold in the F8 generation of the EB-Sel population was observed compared to the Unsel-Lab (F8) population. The EB-Sel and Unsel-Lab populations were treated with their respective lethal and sub-lethal concentrations which resulted in an extended development period, decreased larval survival, and adult emergence along with increased morphological abnormalities in adults. Significant reductions were observed in both male and female longevity, fecundity, egg hatching, net reproductive rate (R0), intrinsic rate of increase (rm), and finite rate of increase (λ) in EB-Sel and Unsel-Lab populations. Higher concentrations of the insecticide also reduced the relative fitness (Rf) of S. litura larvae, with maximum effect at LC50 of the EB-Sel population where the Rf value was 0.32 compared to the Unsel-Lab population. Both populations have been affected by emamectin benzoate exposure, however, the impact was more pronounced in the EB-Sel population indicating fitness costs. Our results suggested the fitness cost linked to emamectin benzoate resistance in S. litura which might favor managing insecticide resistance by reducing the frequency of resistant alleles by removing selection pressure. Consequently, our research provides significant insights to devise better pest management strategies for S. litura.

Marking Helicoverpa zea (Lepidoptera: Noctuidae) with fluorophores for use in mark-release-recapture research

Abstract Knowledge of insect dispersal and long-distance migratory flight capacity and patterns represent key factors needed for risk assessment of invasive pest species, insecticide resistance management, and more effective pest control. Having operative tools to both mark and track insect pest movement is therefore critical to achieving such goals. Here, we describe a new procedure for marking Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), one of the most economically important crop pests in the United States. Adult H. zea moths were effectively marked using the liquid fluorophore cartax green, a persistent UV-fluorescent pigment, both directly by topical application and indirectly by briefly submerging pupae in the marking solution prior to adult emergence. Regardless of the application method, the cartax mark was retained on the moths throughout their entire adult lifespan. No mortality differences were observed between cartax green-marked and water-marked (control) moths. Additionally, using rotary flight mills, we found no significant differences in several flight parameters, including total number of flights, flight speeds, flight distances, or flight durations between unmarked and cartax-marked moths. Under laboratory conditions, we did observe the lateral transfer of different colored fluorophores between moths, indicating that undesirable marking could potentially occur. Moreover, we found that not all fluorophores were equally retained on H. zea moths, with cartax green remaining intact on moths longer than did a corresponding magenta fluorophore. The results show that cartax green fluorophore could be a practical marker for H. zea and other holometabolous species targeted for large-scale mark-release-recapture research.

Adolescent risk behaviours are associated with educational attainment in early adulthood: results from the Raine Study cohort

BackgroundHigher educational attainment is important for economic wellbeing and associated with better health and longevity. Previous research focused on intelligence, socioeconomic status and mental health or individual risk behaviours as predictors of educational attainment, but the role of multiple domains of adolescent risk behaviours is less clear. This study examined the association between multiple domains of risk behaviour in adolescence and educational attainment by 22 years-of-age.MethodsYoung people (Generation 2, Gen2) and their parents (Generation 1, Gen1) participating in the Raine Study completed questionnaires at years 1, 5, 8, 10 (Gen1 only), 14, 17 (both) and 22 (Gen2 only). The Raine Study is an ongoing longitudinal study initiated in Perth, Western Australia, between 1989 and 1991. The 1,102 Gen2 participants who responded to questions about highest educational attainment were included in this study. The association between Gen2 self-reported risk behaviours (including age at commencement of drinking alcohol, smoking, sexual intercourse and drug use) and educational attainment (defined as self-reported years of completed high school: ≤10, 11, 12 or tertiary education (> 12)) at year 22, after adjusting for mother’s age and combined parental education level, participant sex, and family income, educational performance and adolescent mental health, was explored using ordinal regression models and presented as odds ratios (OR) with 95% confidence intervals (CI).ResultsOrdinal models suggested that never smoking or starting older than 18 compared with smoking before age 15 (OR 2.02, 95%CI: 1.28–2.14); first drinking alcohol between 15 and 17 years compared with younger than 15 (OR 1.52, 95%CI: 1.08–2.14); and, first sexual intercourse aged ≥ 18 years compared with under 15 (OR 1.67, 95%CI: 1.08–2.57) were associated with higher levels of educational attainment at 22-year follow-up. Additionally, lower (“better”) behavioural scores increased the odds of higher levels of attainment.ConclusionsAbsence of health risk behaviours at a younger age or later commencement was associated with higher educational attainment. Evidence-based interventions that address the societal influences underpinning risk behaviours in adolescents may support longer school retention.

Adult dietary experience influences mortality of the pest melon fly, Zeugodacus cucurbitae (Diptera: Tephritidae), to an ingested toxin

AbstractIngested toxins formulated as baits can be effective in the management of insect pests, but their efficacy may be influenced by insect foraging alongside active ingredients. There are several components that might influence insect consumption of toxic baits, one of which being prior nutritional exposure. In our study, we investigated how protein deprivation following adult emergence influences lethal and sublethal effects of boric acid on the pest tephritid melon fly, Zeugodacus cucurbitae. We performed a series of experiments to address the impact of prior diet on mortality, diet consumption, enzymes involved in detoxification and antioxidation and fly activity. Newly emerged melon fly adults were provided either diet containing 3:1 sucrose/yeast hyrdrolysate or just sucrose for three days prior to bioassays. Overall, protein deprivation had a strong effect on fly interactions with boric acid. In two separate experiments (continuous exposure and short duration feeding), insects only pre‐fed sucrose had significantly higher mortality compared with those pre‐fed protein. Insects that were pre‐fed only sucrose removed more liquid diet over the same duration of the experiments, suggesting compensatory foraging behaviours. Adults pre‐fed sucrose had higher catalase (1.5×) and superoxide dismutase (1.7×) activities compared with adults pre‐fed sucrose‐yeast, but we found no effect of boric acid on their activity or that of glutathione‐S‐transferase or acetylcholinesterase activity. Boric acid consumption also significantly reduced the activity of melon flies. Overall, our results demonstrate that prior diet in fly adulthood can impact subsequent exposure to and efficacy of ingested toxicants.

Perceptual sensitivity to labeling stereotyped emotion expressions: Associations with age and subclinical psychopathology symptoms from childhood through early adulthood.

This study investigates (a) age-related differences in how the intensity of stereotyped facial expressions influence the emotion label children, adolescents, and adults assign to that face and (b) how this perceptual sensitivity relates to subclinical symptoms of psychopathology. In 2015-2016, 184 participants aged 4-25 years viewed posed stereotypes of angry, fearful, sad, and happy expressions morphed with neutral expressions at 10%-90% intensity. Thin plate regression smoothing splines were used to chart nonlinear associations between age and the perceptual threshold participants needed to assign the emotion label expected based on cultural consensus. Results suggest that sensitivity to labeling stereotypical happy faces as "happy" peaked by age 4. Sensitivity to perceiving stereotypical angry faces as "angry" increased from ages 4 to 7 and then plateaued. In contrast, sensitivity to perceiving stereotypical fearful and sad faces demonstrated protracted development, not reaching a plateau until ages 15 and 16, respectively. Reduction in selecting the "I don't know" response was the primary driver of these age-related changes. Stereotyped fear expressions required the highest intensity to be labeled as such and showed the most marked change in perceptual threshold across development. Interestingly, lower intensity morphs of stereotypical fear faces were frequently labeled "sad." Furthermore, perceiving lower intensity fear morphs was associated with fewer internalizing and externalizing symptoms in participants aged 7-19. This study describes the development of perceptual sensitivity to labeling stereotypical expressions of emotion according to cultural consensus and shows that how people perceive and categorize ambiguous facial expressions is associated with vulnerability to psychopathology.
