Iltamiocel Autologous Cell Therapy for the Treatment of Female Stress Urinary Incontinence: A Double-Blind, Randomized, Stratified, Placebo-Controlled Trial.

This study aimed to determine the efficacy and safety of iltamiocel investigational autologous muscle cell therapy in females with stress urinary incontinence (SUI). Adult females were randomized 2:1 to iltamiocel (150 × 106 cells) or placebo and stratified by severity and prior SUI surgery. The primary objective was efficacy based on the frequency of stress incontinence episodes (SIE) recorded in a 3-day diary at 12 months posttreatment. After 12 months, placebo participants could elect to receive open-label iltamiocel. Efficacy and safety analyses were performed using all patients as treated populations. The study enrolled 311 patients, 297 were randomized to either iltamiocel (n = 199) or placebo (n = 98). Of the 295 participants that completed 12 months blinded follow-up, the proportion achieving the primary endpoint of ≥ 50% SIE reduction was not statistically different between treatment groups (52% vs. 53.6%; p = 0.798). A significantly greater proportion of iltamiocel participants in the prior SUI surgery stratum group achieved ≥ 75% SIE reduction compared with placebo, (40% vs. 16%; p = 0.037). Treatment response was maintained at 24 months in 78.4% and 64.9% of iltamiocel participants who achieved ≥ 50% and ≥ 75% SIE reduction, respectively, at Month 12. Adverse events related to the treatment were reported in 19 (9.5%) iltamiocel participants and 6 (6.1%) placebo participants. The study did not meet its primary endpoint however, iltamiocel cell therapy is safe and may be ideally suited to female patients who have undergone prior surgery for SUI. Additional study in this group of patients with high unmet medical needs is warranted. ClinicalTrials.gov identifier: NCT01893138; EudraCT number: 2014-002919-41.

Efficacy of internet-based cognitive behavioral and interpersonal treatment for depression in Arabic speaking countries: A randomized controlled trial

BackgroundPolitically and economically unstable contexts have been associated with increased prevalence rates of depression. Despite high demand, the availability of mental health experts and care systems is limited in Arabic-speaking countries. Internet-based interventions might provide an opportunity to treat patients independently of location. Therefore, we investigated the efficacy of internet-based cognitive behavioral treatment (iCBT) and interpersonal treatment (iIPT) for depression in Arabic-speaking countries. MethodsIn total, 743 Arabic-speaking adults with depression were randomly allocated to iCBT (n = 243), iIPT (n = 247), or waitlist (n = 253). Depressive, anxiety, and somatoform symptoms, perceived social support and quality of life (QoL) were assessed at pre-, and post-treatment and at three months follow-up. Multiple imputation was performed for missing data. Changes associated with treatment were analyzed using regression in the completer and intention-to-treat sample. ResultsParticipants in both treatment groups showed lower depressive and anxiety symptom severity, higher QoL, and perceived social support compared to the waitlist group (p < .001). Somatoform symptom severity was significantly lower in participants receiving iIPT compared to waitlist (p < .001). Differences between the two treatments in all outcomes were non-significant (p > .05). Three-month follow-up treatment effects regarding depressive symptoms were indicated. LimitationsThe sample mainly consists of educated, single, female adults. Three-month follow-up results rely on a small subsample and must be interpreted with caution. ConclusionsThis is the first randomized controlled trial to demonstrate the efficacy of iCBT and iIPT for depression in Arabic-speaking countries. It provides first indications that internet-based interventions might help specific individuals in this region.

Trunk-to-leg volume and appendicular lean mass from a commercial 3-dimensional optical body scanner for disease risk identification

Body shape expressed as the trunk-to-leg volume ratio is associated with diabetes and mortality due to the associations between higher adiposity and lower lean mass with Metabolic Syndrome (MetS) risk. Reduced appendicular muscle mass is associated with malnutrition risk and age-related frailty, and is a risk factor for poor treatment outcomes related to MetS and other clinical conditions (e.g.; cancer). These measures are traditionally assessed by dual-energy X-ray absorptiometry (DXA), which can be difficult to access in clinical settings. The Shape Up! Adults trial (SUA) demonstrated the accuracy and precision of 3-dimensional optical imaging (3DO) for body composition as compared to DXA and other criterion measures. Here we assessed whether trunk-to-leg volume estimates derived from 3DO are associated with MetS risk in a similar way as when measured by DXA. We further explored if estimations of appendicular lean mass (ALM) could be made using 3DO to further improve the accessibility of measuring this important frailty and disease risk factor. SUA recruited participants across sex, age (18-40, 40-60, >60 years), BMI (under, normal, overweight, obese), and race/ethnicity (non-Hispanic [NH] Black, NH White, Hispanic, Asian, Native Hawaiian/Pacific Islander) categories. Each participant had whole-body DXA and 3DO scans, and measures of cardiovascular health. The 3DO measures of trunk and leg volumes were calibrated to DXA to express equivalent trunk-to-leg volume ratios. We expressed each blood measure and overall MetS risk in quartile gradations of trunk-to-leg volume previously defined by National Health and Nutrition Examination Survey (NHANES). Finally, we utilized 3DO measures to estimate DXA ALM using ten-fold cross-validation of the entire dataset. Participants were 502 (273 female) adults, mean age=46.0±16.5y, BMI=27.6±7.1kg/m2 and a mean DXA trunk-to-leg volume ratio of 1.47±0.22 (females: 1.43±0.23; males: 1.52±0.20). After adjustments for age and sex, each standard deviation increase in trunk-to-leg volume by 3DO was associated with a 3.3 (95% odds ratio [OR]=2.4-4.2) times greater risk of MetS, with individuals in the highest quartile of trunk-to-leg at 27.4 (95% CI: 9.0-53.1) times greater risk of MetS compared to the lowest quartile. Risks of elevated blood biomarkers as related to high 3DO trunk-to-leg volume ratios were similar to previously published comparisons using DXA trunk-to-leg volume ratios. Estimated ALM by 3DO was correlated to DXA (r2=0.96, root mean square error=1.5kg) using ten-fold cross-validation. Using thresholds of trunk-to-leg associated with MetS developed on a sample of US-representative adults, trunk-to-leg ratio by 3DO after adjustments for offsets showed significant associations to blood parameters and MetS risk. 3DO scans provide a precise and accurate estimation of ALM across the range of body sizes included in the study sample. The development of these additional measures improves the clinical utility of 3DO for the assessment of MetS risk as well as the identification of low muscle mass associated with poor cardiometabolic and functional health.

Alexithymia As a Mediator in The Relationship of Posttraumatic Stress with Anxiety During the Covid-19 Pandemic

There has been an increase in the levels of many psychological problems including anxiety and post-traumatic stress disorder (PTSD) during the COVID-19 pandemic. Alexithymia can be considered an important psychological problem. However, it may be difficult to differentiate between post-traumatic stress symptoms (PTSS), anxiety symptoms, and alexithymia because they share symptoms like avoidance. To develop psychological interventions, it will be useful to determine the extent to which alexithymia influences PTSS and anxiety. This study examined alexithymia as a mediator in the relationship of PTSS with anxiety during the COVID-19 pandemic in Türkiye. The sample consisted of 417 male and female adults aged between 18 to 68. Pearson Moment Correlation Coefficients and Structural Equation Modeling were computed to examine the relationships. Data were gathered through Demographic Information Form, Post-Traumatic Stress Disorder Checklist, Beck Anxiety Inventory, and Toronto Alexithymia Inventory. Findings showed that PTSS were related to alexithymia and anxiety, and alexithymia was associated with anxiety. Moreover, alexithymia had a partial mediator effect in the relationship of PTSS with anxiety. The findings highlight the importance of mental health professionals to consider alexithymia when evaluating and planning treatment for individuals with PTSS and anxiety.

Bilateral Hydrocele of the Canal of Nuck in an Adult Female: A Case Report

Bilateral hydrocele of the canal of Nuck (HCN) is very rare, in adult females. Primary care physicians can misdiagnose this pathology without diagnostic imaging. A 37-year-old female complained of right lower quadrant (RLQ) pain, for a few months, reported to the emergency room. A non-reducible bulging protrusion was visualized in the RLQ. After performing the necessary blood work, the emergency physician ordered an emergent sonogram and computed tomography (CT). A transvaginal sonogram was performed to exclude gross adnexal masses, in the RLQ. An HCN canal was suspected in the right inguinal region. A non-contrast CT demonstrated a bilateral HCN, with the left significantly smaller than the right. In this case, a bilateral surgical excision of the hydrocele was recommended. Owing to the recurrence of the HCN, a cyst aspiration was not suggested. Physicians should consider the diagnosis of HCN in any female presenting with inguinolabial swelling. Sonography, CT, and magnetic resonance imaging (MRI) are the three diagnostic imaging techniques commonly used to diagnose this pathology. A multimodality approach is sometimes necessary when the sonography diagnosis is no definitve.

Integrative gene regulatory network analysis discloses key driver genes of fibromuscular dysplasia.

Fibromuscular dysplasia (FMD) is a poorly understood disease affecting 3-5% of adult females. The pathobiology of FMD involves arterial lesions of stenosis, dissection, tortuosity, dilation and aneurysm, which can lead to hypertension, stroke, myocardial infarction and even death. Currently, there are no animal models for FMD and few insights as to its pathobiology. In this study, by integrating DNA genotype and RNA sequence data from primary fibroblasts of 83 patients with FMD and 71 matched healthy controls, we inferred 18 gene regulatory co-expression networks, four of which were found to act together as an FMD-associated supernetwork in the arterial wall. After in vivo perturbation of this co-expression supernetwork by selective knockout of a top network key driver, mice developed arterial dilation, a hallmark of FMD. Molecular studies indicated that this supernetwork governs multiple aspects of vascular cell physiology and functionality, including collagen/matrix production. These studies illuminate the complex causal mechanisms of FMD and suggest a potential therapeutic avenue for this challenging disease.

Molecular characterization and CRISPR/Cas9 validation of the precursor of egg yolk protein gene, vitellogenin of Leucinodes orbonalis Guenée (Lepidoptera: Crambidae)

Vitellogenin (Vg), a yolk protein precursor, plays an important role in the oocyte development of insects and is an important target of genetic pest management. Vg is synthesized in the fat body, transported through haemolymph and accumulates in developing oocytes. In this regard, the eggplant shoot and fruit borer, Leucinodes orbonalis (Lepidoptera: Crambidae) is the major pest in South and South East Asia and a serious concern for farmers. Therefore, in the present study, we have cloned and characterized Vg from L. orbonalis (LoVg) for further applications. The cloned Vg consisted of 5,370 base pairs encoding 1,790 amino acid residues long protein. Further, sequence alignment revealed that LoVg has three conserved domains: a Vitellogenin N domain (LPD-N), a domain of unknown function protein families (DUF1943), and a von Willebrand factor type D domain (VWD). Using phylogenetic analysis, it was found that LoVg evolved alongside homologous proteins from different insects. The real-time expression levels of LoVg were significantly greater in female adults followed by the pupal stage. This suggests that Vg production and absorption in L. orbonalis occurs in the later pupal stage. Our studies showed that editing LoVg using CRISPR/Cas9 did not affect the total number of eggs laid but affected egg hatchability. These studies help us to design newer approaches in insect pest management through genetic suppression for sustainable pest management.

Brain encoding of naturalistic, continuous, and unpredictable tactile events.

Studies employing EEG to measure somatosensory responses have been typically optimized to compute event-related potentials in response to discrete events (ERPs). However, tactile interactions involve continuous processing of non-stationary inputs that change in location, duration, and intensity. To fill this gap, this study aims to demonstrate the possibility of measuring the neural tracking of continuous and unpredictable tactile information. Twenty-seven young adults (females = 15) were continuously and passively stimulated with a random series of gentle brushes on single fingers of each hand, which were covered from view. Thus, tactile stimulations were unique for each participant, and stimulated fingers. An encoding model measured the degree of synchronization between brain activity and continuous tactile input, generating a temporal response function (TRF). Brain topographies associated with the encoding of each finger stimulation showed a contralateral response at central sensors starting at 50 ms and peaking at about 140 ms of lag, followed by a bilateral response at about 240 ms. A series of analyses highlighted that reliable tactile TRF emerged after just 3 minutes of stimulation. Strikingly, topographical patterns of the TRF allowed discriminating digit lateralization across hands and digit representation within each hand. Our results demonstrated for the first time the possibility of using EEG to measure the neural tracking of a naturalistic, continuous, and unpredictable stimulation in the somatosensory domain. Crucially, this approach allows the study of brain activity following individualized, idiosyncratic tactile events to the fingers.Significant Statement This study expands the current research conducted on neural tracking, opening the exploration of idiosyncratic tactile events and overcoming constraints of laboratory tasks that typically rely on discrete events. We validated a protocol for the ecological investigations of continuous, slow, tactile processing of the hands. The employed approach enriches the possible use of the EEG to characterize somatosensory neural representations of tactile events. Findings unravel coherent neural responses to continuous and naturalistic touch, with sensitivity for digit lateralization and representation.

High early lactational synchrony within baboon groups predicts increased infant mortality.

Social group composition can have fitness implications for group members by determining opportunities for affiliative and competitive interactions. Female-female competition may be particularly acute when many groupmates have young infants at the same time, with potential consequences for infant survival. Here, we used decades of data on wild baboons (Papio sp.) in Amboseli, Kenya, to examine the effects of 'early lactational synchrony' (here, the proportion of females in a group with an infant <90 days old) on female-female agonistic interactions and infant survival. Because early lactation is an energetically demanding time for mothers and a risky time for infants, we expected early lactational synchrony to produce intensified competition for food and/or male protectors, resulting in more frequent female-female agonistic interactions and high infant mortality. In support of these predictions, we found that the frequency of female-female agonistic interactions increased with increasing early lactational synchrony. Reproductive state affected this relationship: while females in all states (cycling, pregnant, and postpartum amenorrhea) initiated more agonistic interactions when early lactational synchrony was high, only females in postpartum amenorrhea (including, but not limited to, females in early lactation) received more agonistic interactions. Furthermore, while high early lactational synchrony was rare, it strongly predicted infant mortality. This association may result from both aggression among adult females and infanticidal behavior by peripubertal females. These findings provide novel evidence that social dynamics may shape reproductive phenology in a nonseasonal breeder. Specifically, both competition among reproductive females and harassment from nonreproductive females may select against synchronous reproduction.

The Efficacy and Safety of CollaSel Pro® Hydrolyzed Collagen Peptide Supplementation without Addons in Improving Skin Health in Adult Females: A Double Blind, Randomized, Placebo-Controlled Clinical Study Using Biophysical and Skin Imaging Techniques.

Background: This study aimed to evaluate the efficacy and safety of oral hydrolyzed collagen peptide (HCP) in healthy females by assessing the skin parameters via biophysical and skin imaging techniques. Methods: 112 females were randomly assigned to receive either HCP (n = 57; 10 g CollaSel Pro®) or placebo (n = 55; 10 g maltodextrin) daily for eight weeks. The contribution of HCP to skin elasticity, hydration, and roughness was investigated against a placebo, while the facial soft tissue sagging (RMS) and safety data were also recorded. Results: HCP was associated with significant improvements in skin elasticity (p = 0.009), skin hydration (p ranged from 0.003 to <0.001), and skin roughness (p ranged from 0.002 to <0.001). In the HCP vs. the placebo group, week eight values for skin elasticity (43.0 (7.4) vs. 40.3 (3.3) mPa, p = 0.017), skin hydration (65.8 (18.9) vs. 53.1 (14.9) g/m3, p < 0.001) and skin roughness (40.2 (20.4) vs. 24.9 (20.9) g/m3, p < 0.001) were significantly higher. In the HCP group, week 8 RMS values were significantly lower than baseline values (1.02 (0.21) vs. 1.10 (0.21) mm, p = 0.012). Conclusions: CollaSel Pro® HCP can be considered a well-tolerated, safe product that effectively improves dermal health and the appearance of sagging and ameliorates the signs of the aging process.

Revision of the Genus &amp;lt;i&amp;gt;Aethalodes&amp;lt;/i&amp;gt; with a New Subspecies from Anhui, China (Cerambycidae: Lamiinae)

&amp;lt;i&amp;gt;Aethalodes &amp;lt;/i&amp;gt;is a tiny genus in the subfamily Lamiinae Latreille, 1825 of the family Cerambycidae Latreille, 1802. It was established in 1888 with &amp;lt;i&amp;gt;Aethalodes verrucosus &amp;lt;/i&amp;gt;Gahan, 1988 as the type species. In order to have a better and more complete understanding of this genus and the two known subspecies, the scientific literature on the genus and 2 known subspecies was traced with the original descriptions carefully studied, and all the type specimens available are found to be female adults, which have been examined and compared with each other and also with the identified male specimens from other reliable sources. A revision of the genus &amp;lt;i&amp;gt;Aethalodes &amp;lt;/i&amp;gt;and the two known subspecies has been made, as the original descriptions of the genus and nominate type subspecies by Gahan were incomplete and somewhat defective in lack of the male type specimen. The subspecies &amp;lt;i&amp;gt;Aethalodes verrucosus formosanus &amp;lt;/i&amp;gt;Kriesche, 1924 is raised back to species level as &amp;lt;i&amp;gt;A. verrucosus formosanus&amp;lt;/i&amp;gt; Kriesche, 1924 based on the newly-found significant differences in the length of the antennae as the decisive feature distinguishing it from &amp;lt;i&amp;gt;A. verrucosus &amp;lt;/i&amp;gt;as an independent species. Fieldwork has been carried out to try to find and collect &amp;lt;i&amp;gt;Aethalodes &amp;lt;/i&amp;gt;specimens with light and net trappings, and a new subspecies, &amp;lt;i&amp;gt;Aethalodes&amp;lt;/i&amp;gt; &amp;lt;i&amp;gt;verrucosus anhuiensis&amp;lt;/i&amp;gt; subsp. nov. is described from China’s Anhui Province with images, whose unique partial white squamosity on the black body is distinguished from the dark brown squamosity of the nominate subspecies. Both &amp;lt;i&amp;gt;Aethalodes verrucosus verrucosus &amp;lt;/i&amp;gt;Gahan, 1988 and the newly-found subspecies may be rare in China. More field surveys are required to find and observe &amp;lt;i&amp;gt;Aethalodes&amp;lt;/i&amp;gt; adults, their host plants and habitat in China, and efforts should be made to collect more specimens for further study.

Understanding the role of Bacillus subtilis GEB1 in enhancing guava plant immunity against Meloidogyne enterolobii: A multifaceted approach

Guava root-knot nematode, Meloidogyne enterolobii has emerged as a significant threat to guava cultivation, impacting production worldwide. By integrating the molecular, histopathological and in silico approaches the current study explores the efficacy of Bacillus subtilis GEB1 in enhancing the resistance of guava against M. enterolobii. The gene expression studies reveal that guava plants treated with B. subtilis and challenged with nematodes at 72 h showed 2 fold increase in phytoene synthase, 2.1 fold increase in mitogen-activated protein kinase, 1.54 fold increase in phenylalanine ammonia-lyase and 1.82 fold increase in peroxidase genes when compared to untreated control. The Scanning electron microscope analysis of guava roots treated with B. subtilis revealed the presence of spores in the rhizoplane region which led to deter the invading nematodes. The comparative histological studies with guava roots treated with B. subtilis revealed lesser damage in the cortex, vascular regions with limited hypertrophy and hyperplasia, lesser adult females, and feeding traces with minimum root, stele and cortex diameter and thickness than those of untreated infested roots. Attempts were made to dock the plant functional proteins with B. subtilis peptides to understand their interaction. The results revealed that bacillobactin showed a greater binding affinity of −9.0 kcal/mol with phytoene synthase, plipstatin (−16.0 kcal/mol), and fengycin (−15.9 kcal/mol) with MAPK proteins of guava. Overall, the current study offers insight into the intricate mechanisms of plant-nematode-bacteria interactions and underscores the importance of B. subtilis GEB-1 as a biocontrol agent to combat Meloidogyne enterolobii infection in guava.

A review of the Margarodidae sensu stricto (Hemiptera: Coccomorpha) in China, with descriptions of three new species

The research history of the family Margarodidae Cockerell sensu stricto (Hemiptera: Coccomorpha) from China is reviewed. Four species of Porphyrophora Brandt and three species of Neomargarodes Green from China are described and illustrated, including three new species: Neomargarodes chenopodium Zheng &amp; Wu, sp. nov. based on the morphology of the adult female, first-instar nymph and second-instar female and male nymphs (cysts); Porphyrophora ejinensis Zheng &amp; Wu, sp. nov. based on the adult female, second-instar female nymph (cyst) and third-instar female nymph (cyst); and Porphyrophora neimonggolensis Zheng &amp; Wu, sp. nov. based on the adult female. Porphyrophora ningxiana Yang, 1979, stat. rest. is resurrected from synonymy under Porphyrophora sophorae (Archangelskaya, 1935), and lectotypes of Neomargarodes gossypii Yang, 1979 and P. ningxiana Yang are designated. A record of Porphyrophora ussuriensis Borchsenius, 1949 from China was found to be based on a misidentification. An identification key to genera and species of Margarodidae s.s. found in China is provided, based on adult female morphology.

Volcanic ash in the water column: Cellular, physiological and anatomical implications for the gastropod suspension-feeder Crepipatella peruviana (Lamarck, 1822)

The influx of volcanic ash into seawater alters particle composition with implications for the cellular, physiological and anatomical response of suspension-feeding organisms. Adult females of Crepipatella peruviana were exposed to three diets consisting of a fixed concentration of 50,000 cells ml−1 of the microalga Isochrysis galbana plus different concentrations of ash particles (30, 90 and 150 mg L−1). The objective was to determine the cellular, physiological and anatomical responses. Mortality increased with ash concentrations, while feeding and respiration rates, tissue weight, and condition index decreased. The gills showed severe degradation of cilia and the presence of large mucous aggregates of cilia and ash. An increase in ash resulted in decreased lipid peroxidation and protein carbonyls, but increased total antioxidant capacity and phenols. Thus, volcanic ash particles may exert a high impact at both cellular and physiological levels for C. peruviana, where inhibition of gill function reduces the ability to acquire food.

Association between dietary choline intake and asthma and pulmonary inflammation and lung function: NHANES analysis 2009–2018

BackgroundAsthma is a chronic inflammatory condition, and choline may alleviate airway inflammation and oxidative stress but studies on the association between dietary choline and asthma remain limited. The purpose of this study is to investigate the associations between dietary choline intake and asthma, as well as pulmonary inflammation and lung function in children and adults.MethodsIn our research, we employed the data of the National Health and Nutrition Examination Survey (NHANES) from 2009 to 2018, including 7,104 children and 16,580 adults. We used fractional exhaled nitric oxide (FENO) to assess pulmonary inflammation and forced expiratory volume in one second (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio, peak expiratory flow rate (PEF), predicted FEV1% and predicted FVC% to assess lung function. Binary logistic regression, linear regression, and the restricted cubic splines were used to analyze the associations between dietary choline intake and asthma and pulmonary inflammation and lung function.ResultsIn children, we observed the positive associations between the natural logarithmic transformation of choline (ln-choline) and ln-FEV1 [ β:0.011; 95%CI: (0.004,0.018)] and ln-FVC [ β:0.009; 95%CI: (0.002,0.016)]. In adult males, the ln-choline was positively associated with ln-FEV1[ β:0.018; 95%CI: (0.011,0.024)], ln-FVC [ β:0.020; 95%CI: (0.014,0.026)], ln-PEF [ β:0.014; 95%CI: (0.007,0.022)], ln-predicted FEV1% [ β: 0.007; 95%CI: (0.001, 0.013)] and ln-predicted FVC%[ β: 0.010; 95%CI: (0.005, 0.015)] and negatively associated with FENO [ β: -0.029; 95%CI: (-0.049, -0.009)]. In unadjusted and partially adjusted models, adult females with ln-choline in the highest quartile had 25.2% (95%CI:9.4-38.3%) and 23.8% (95%CI:7.6-37.1%) decreased odds of asthma compared to those with the lowest quartile group. In the dose-response relationships of dietary choline and pulmonary inflammation and lung function indicators in adults, there existed threshold and saturation effects.ConclusionThe associations between dietary choline and lung function indicators such as FEV1 and FVC are positive in children and adults. The association between dietary choline and pulmonary inflammation is negative only in adults.

Broad geographic variation in age- and sex-dependent origin of harvested eurasian wigeon (Mareca penelope) revealed by stable-hydrogen (δ2H) isotope analyses of feathers

Migratory waterfowl are a harvested resource shared among multiple European countries, exposing them to potential overexploitation. Management of take is challenging since the life cycle of migratory waterfowl consists of several stages distributed among several locations, with possible spatio-temporal overlap among populations with differing population trends. Successful harvest management in such situations requires knowledge about the connections between breeding and non-breeding locations, and where birds are harvested. Breeding populations of Eurasian wigeon (Mareca penelope) are declining in Finland, underlining the need for more effective harvest management. Relative proportions and temporal distribution of local breeding birds and migrants from a larger Russian breeding population within the Finnish hunting bag has been unknown to date. We studied spatio-temporal origins of Finnish harvested wigeon by measuring stable-hydrogen (δ2H) isotope values from legally harvested birds. We modelled the changes in δ2H values of the feather samples within the hunting season using Gaussian processes and found that the origin of harvested wigeon in Finland changed during the hunting season and differed by age and sex. In juveniles and adult females but not in adult males, origin of harvested birds shifted from local and possibly western Russian birds to more long-distance migratory birds during the harvest season. These patterns likely reflected sex- and age-specific differences in migratory behaviour of Eurasian wigeon in the East Atlantic flyway, which can be used to guide future management and conservation of this species through the implementation of spatio-temporal harvest regulation.

Protective Factors as Mediators Between Trauma and Internalizing Difficulties Among Male and Female Young Adults

The goal of this study was to examine the indirect effect of protective factors (i.e., resilience, coping, and self-esteem) on the association between exposure to traumatic events in childhood and internalizing difficulties for men and women. We surveyed 583 young adults aged 18 to 25 years about past exposure to traumatic events and current internalizing difficulties. The results suggest that there is a significant indirect effect of protective factors on the association between lifetime traumatic event exposure and internalizing distress. Furthermore, there was a gender difference between groups for the indirect effect of protective factors; protective factors had a mediating effect for women but not for men. This study highlights the importance of protective factors in understanding why some individuals experience internalizing difficulties after exposure to traumatic events. When working with victims of traumatic events, it is essential to consider their sex and the presence of protective factors such as coping, resilience, and self-esteem.

Performance of the MiniMed 780G system on mitigating menstrual cycle-dependent glycaemic variability.

To map the glycaemic variabilities and insulin requirements across different phases of the menstrual cycle and assess the efficacy and performance of the MiniMed 780G system on mitigating glycaemic variabilities during phases of the menstrual cycle. A pilot study recruiting 15 adolescent and young adult females with type 1 diabetes was conducted. Only females with regular spontaneous menstruation were enrolled in the current study. Phases of each menstrual cycle were determined as either follicular phase or luteal phase. The study analysed continuous glucose monitoring metrics during two study periods: the open loop period (OLP) and the advanced hybrid closed-loop (AHCL) period; each period lasted 3 consecutive months. During the OLP, the mean time in range (TIR) significantly decreased during the luteal phase compared with the follicular phase (65.13% ± 3.07% vs. 70.73% ± 2.05%) (P < .01). The mean time above range significantly increased from 21.07% ± 2.58% during the follicular phase to 24.87% ± 2.97% during the luteal phase (P < .01). After initiating the AHCL period, TIR was comparable during both phases of the menstrual cycle (P = .72), without increasing the time spent below 70 mg/dL (P > .05). Regarding insulin delivery during the AHCL period, the percentage of Auto basal and Auto correction delivered by the algorithm increased by 13.55% and 30.6%, respectively (P < .01), during the luteal phase. The fully automated adaptive algorithm of the MiniMed 780G system mitigated menstrual cycle-dependent glycaemic variability, successfully attaining the recommended glycaemic outcomes with a TIR greater than 70% throughout the entire menstrual cycle.

Comparative analysis of the nutritional composition and volatile compounds in male and female adults, nymphs, and molts of Eupolyphaga sinensis Walker.

Female adult Eupolyphaga sinensis Walker (FAESW) has traditionally been a food source in Southeast Asian countries such as China and India, due to its rich nutritional content. However, the nutritional value of male adults (MAESW) and its molts (MESW) has hardly been reported. Therefore, this study aims to explore the potential application of MAESW and MESW in food by investigating and comparing their nutritional composition (i.e., protein, amino acids, fatty acids, and essential elements) with traditional sources of nutrition. The protein content of MAESW and MESW was 66.10±0.49% and 59.86±6.07%, respectively, and the highest energy content (462.26±1.28kcal/100g) was observed for MAESW. Eight essential amino acids were determined, of which the males and MESW were found to have higher contents than those of FAESW (p<0.05). Oleic and linoleic acid contents were higher in the adults than nymphs. Moreover, MESW was predominant in calcium (6770.84mg/kg), whereas MAESW was rich in iron (556.12mg/kg). Likened to chicken, the protein, amino acid, fatty acid, and mineral contents of ESW were higher. The volatiles of ESW were related to hexaldehyde, benzaldehyde, acetic acid, and butyric acid. This study provides a better understanding of the chemical composition of ESWs during their growth cycle and helps optimize information on edible insects, promoting their use as a potential food source for humans. As a kind of edible insect, the utilization of adult male Eupolyphaga sinensis Walker (ESW) and its molt is very low at present. Therefore, this study examined the nutrients and volatile substances of ESW (at different growth stages) and molt, which provided a theoretical basis for the subsequent development and utilization of ESW.

Effects of muscle quantity, muscle quality, and phase angle on whole-body reaction time in 5164 adults aged 20-91years.

Muscle quantity, defined as appendicular lean mass (ALM); muscle quality, defined as the ratio of muscle strength to ALM; and bioelectrical impedance analysis (BIA)-derived phase angle (PhA) are determinants of physical performance. We examined whether muscle quality indices were significant predictors of the whole-body reaction time (WBRT) in healthy female and male adults aged 20-91years. Data from 5164 adults (2869 women and 2295 men; mean age ± standard deviation, 60.9 ± 15.6years) were analyzed. Height and weight were measured, and body mass index was calculated. ALM was estimated using a previously validated 8-electrode multi-frequency BIA. PhA was measured at 50kHz using a BIA device. Knee extension strength (KES), leg extension power (LEP), and flexibility were examined. The ALM to weight (ALM/weight), KES to ALM (KES/ALM), and LEP to KES (LEP/KES) ratios were calculated. In the WBRT test, participants were asked to stand on a force plate and jump upright as quickly as possible in response to a light stimulus. The WBRT was divided into the response initiation and motion execution phases. ALM/weight, KES/ALM, LEP/KES, PhA, and flexibility were significant independent predictors of WBRT and the time of the motion execution phase (p < 0.001). However, PhA was not a significant predictor of the time of response initiation phase. Muscle quantity (ALM/weight), muscle quality (KES/ALM and LEP/KES), PhA, and flexibility are determinants of WBRT test performance, particularly in the motion execution phase.
