ABSTRACT

INTRODUCTION: The skin aging process is mainly associated with the appearance of fine wrinkles and flaccid, dry, and dull skin. A hyaluronic acid matrix (HAm) ingredient containing HA, sulfated glycosaminoglycans (GAGs), and collagen is proposed to enhance skin health by improving hydration and structural integrity. The objective of this study was to evaluate the impact of oral supplementation with HAm on skin properties.

METHODS: A 12-week, randomized, double-blind, placebo-controlled trial was designed, including 60 healthy women aged 35-65 with signs of natural skin aging (NCT05813054). Participants were assigned to receive either HAm (Dermial^®; 60 mg daily) or a placebo and were dermatologically assessed after 6 and 12 weeks. Skin properties were determined by the evaluation of stratum corneum hydration (SCH), brightness/glow, wrinkles, dryness, roughness, smoothness, pH, temperature, elasticity, friction, antioxidant capacity, deformability, melanin index, and erythema index. In addition, global satisfaction and adverse reactions were assessed.

RESULTS: Assessments were performed on data from 50 participants as a per-protocol analysis. Skin wrinkles and smoothness (6 weeks), and roughness (12 weeks) significantly improved in the HAm group compared with the placebo group. Participants receiving HAm had significantly increased skin SCH and brightness, and decreased scaliness and temperature at 6 and 12 weeks versus the baseline value. A statistically significant reduction in the erythema index and a balanced pH were also observed in the HAm group. Global satisfaction was significantly higher in HAm as compared to placebo. No serious adverse events associated with the tested products were registered during the study.

CONCLUSIONS: Daily supplementation with HAm effectively improves multiple aspects of skin health and appearance, suggesting its potential as a safe and beneficial antiaging ingredient. These results support the role of HAm in promoting skin brightness/glow and hydration, and reducing the visible effects of aging.

ABSTRACT

PURPOSE: The genus Myobia (Acari: Myobiidae) includes obligate ectoparasites of rodents, with M. murismusculi being the most frequently reported species in laboratory mouse colonies worldwide. However, morphological overlap and nomenclatural confusion have long hindered accurate species identification. This study aims to describe a new fur mite species from Mus musculus and to distinguish it from M. murismusculi and related taxa using detailed morphological and morphometric analyses.

METHODS: Fur mites were collected from laboratory mice in two facilities and examined using light and scanning electron microscopy. Morphological characters were described, measured, and illustrated. Sstandardized morphometric characters were analyzed across multiple Myobia species using principal component analysis (PCA) and permutational multivariate analysis of variance (PERMANOVA) to assess interspecific variation and species boundaries.

RESULTS: The new species, Myobia murina sp. nov., differs from M. murismusculi by longer dorsal setae ve and si. PCA and t-SNE analyses revealed a distinct cluster for M. murina, and PERMANOVA confirmed significant morphological divergence from all examined congeners (R² = 0.873, p < 0.001). An updated identification key for female mites of the subgenus Myobia is also provided.

CONCLUSION: This study demonstrates the utility of morphometric approaches in mite taxonomy and confirms M. murina sp. nov. as a morphologically and statistically distinct species. Accurate species identification is essential for laboratory animal health management and fur mite diagnostics.

ABSTRACT

There is abundant but discrepant scientific literature reporting an effect of opioids on the course of cancer. The International Agency for Research on Cancer monographs recently classified opium consumption as carcinogenic to humans in certain organs, raising concerns this may be due at least in part to the alkaloids opium contains (such as morphine and codeine). This systematic review investigated whether opioid exposure among cancer-free individuals is independently associated with the risk of future cancer incidence or cancer mortality. An electronic database search was conducted in PubMed, EMBASE, Web of Science, PsycINFO, International Pharmaceutical Abstracts, CINAHL and Scopus. Studies were included if they provided a statistical estimate of cancer mortality, cancer incidence, or cancer risk following opioid exposure. Study quality was assessed using the Newcastle-Ottawa Scale. Study characteristics and outcomes were extracted and analysed in a descriptive narrative synthesis. There were 27 studies that met the inclusion criteria, representing a total of 4,542,745 participants. Twelve of the 27 were rated as high quality according to the Newcastle-Ottawa Scale. The observed data is consistent with a small increase in the risk of cancer incidence or cancer mortality following opioid exposure, particularly in a subset of organs. There is, however, considerable uncertainty in the evidence given the substantial risk of bias in estimating the overall effect of opioid exposure on cancer outcomes in these studies. This review synthesises studies reporting cancer risk following opioid exposure and identifies the key methodological factors influencing ongoing uncertainty estimating the true effect. Rigorous epidemiological studies employing specific methods to minimize bias are warranted.

ABSTRACT

This study assessed the efficacy of a plant-based premix of feed additives (PFA) composed of essential oils and vitamins on a farm with 1560 laying hens (ISA Brown line), naturally infested with poultry red mite (PRM), Dermanyssus gallinae. The trial lasted 44 days. The AVIVET traps were used to determine PRM mass, number of eggs, larvae, blood-engorged and unfed nymphs, and adults on day – 12, – 5, and 0 before, and on days 2, 5, 8, 11, 15, 23, and 30, after, hens started to consume PFA. Friedman’s ANOVA was utilised to identify differences between means, and the post hoc Wilcoxon matched Pairs Test was then employed to ascertain the impact of the tested PFA on the D. gallinae population. From the eighth day until the end of the trial period, a statistically lower mass of mites (P < 0.05), the number of nymphs (P < 0.05) and the number of blood-engorged mites (P < 0.05) were observed compared to day 0. In comparison to day 0, a statistically significantly lower number of eggs (P < 0.01) was observed on day 5 (P < 0.05), day 11 (P < 0.01), larvae on day 23 (P < 0.05) and day 30 (P < 0.01), as well as unfed mites on days 15, 23, and 30 (P < 0.01, P < 0.01 and P < 0.001, respectively). Egg production (%, hen-day) in 52-54 weeks of age (control period) was 88.7, while in 55-58 weeks of age (trial period) was 89.5. The results indicate that the tested PFA can control PRM without adversely affecting egg production.

ABSTRACT

PURPOSE: Accurate trauma triage ensures timely and specialized care for potentially critically injured patients. Undertriage remains a concern, particularly for patients without obvious vital sign derangements. This study evaluates the potential of biomarkers such as lactate, base deficit (BD), and blood glucose to improve triage score accuracy in identifying patients with severe injuries (Injury Severity Score [ISS] > 15) and predicting intensive care unit (ICU) admission without a high risk of severe injury (HRSI).

METHODS: This retrospective, single-center cohort study (2017-2021) included trauma patients with trauma team activation (TTA) due to mechanism of injury(MOI) and therefore only patients with moderate risk of severe injury criteria(MRSI). Exclusion criteria were any HRSI-criterion such as advanced airway management, Glasgow Coma Scale < 12, systolic blood pressure < 90 mmHg, and specific injury patterns. Biomarkers were collected upon emergency department (ED) admission. Logistic regression and receiver operating characteristic (ROC) curve analyses evaluated biomarker predictive value alone and in combination with existing triage scores.

RESULTS: The study population included 3371 TTAs of which we were able to include 302 in our study-group. 15% had ISS > 15. These patients had significantly higher lactate (2.38 ± 1.2 vs. 1.57 ± 0.75 mmol/L, p < 0.05), BD (-0.2 ± 5.0 vs. 1.7 ± 2.7 mmol/L, p < 0.05), and blood glucose (144.8 ± 46.0 vs. 118 ± 37.9 mg/dL, p < 0.05). Augmenting triage scores with lactate improved predictive accuracy, with the highest AUC (0.774) observed for the age-lactate model. ICU admission prediction was less robust (AUC = 0.674).

CONCLUSION: Our findings suggest that biomarkers such as lactate could strengthen trauma triage scores, but prospective, multicenter validation is essential to confirm these preliminary results.

ABSTRACT

BACKGROUND: Violent and abusive behavior in relationships causes immense individual and community harm. Mapping the emergence of different types of abuse over time and recognising behavioral patterns, could enable more targeted intimate partner violence (IPV) prevention, screening, and early intervention. While there has been some qualitative research into early warning signs of abuse and escalating homicide risks in relationships, no known studies have asked a large sample of survivors to document the sequence of abusive behaviors in a recent relationship.

OBJECTIVES: To explore timelines of psychologically, physically, and sexually abusive behaviors and life events in a recent relationship (during the last 5 years) to create a macro timeline of abuse.

DESIGN: Cross sectional survey of a nationally representative sample (gender, age, state, locality).

DATA SOURCES AND METHODS: Eight hundred and fifteen Australian IPV women survivors.

RESULTS: Results indicated that psychological abuse was a feature of most violent relationships, and almost always underpinned physical and sexual abuse. Psychological abuse often began before couples moved in together, while physical and sexual abuse came later. The earliest indicators for survivors that something was wrong was being isolated from others and feeling controlled by their partner. For many survivors, growing concern about the impact of abuse on their children occurred around the same time as leaving their relationship and trying to get help.

CONCLUSION: Findings indicate a pattern of escalating behaviors over the course of a relationship that are consistent with the concept of coercive control. The macro timeline contains important learnings for intervening early with future survivors.

ABSTRACT

BACKGROUND: Treatment options for intracranial atherosclerotic stenosis (ICAS) are limited, but endovascular intervention has gained increasing attention in recent years.

AIM: To evaluate the safety and efficacy of the Neuroform EZ stent for treating ICAS in the posterior circulation.

MATERIAL & METHODS: Patients’ (n = 50) eligibility depended on ICAS with severe stenosis (≥ 70%) in the intracranial segment of the vertebral artery or basilar artery shown by cerebral angiography. General information of the participants were recorded, Adverse events during the perioperative period were observed, including in-stent thrombosis, postoperative hyperperfusion, stroke, and mortality. Before the procedure, neurological deficits (NIHSS score) and neurological recovery (mRS score) were recorded at 12 months postoperatively. The degree of vascular stenosis was evaluated prior to and following the procedure, and in-stent restenosis (ISR) was recorded at 12 months post-operation.

RESULTS: Fifty-two stents were successfully placed in 50 patients, followed by standardized medication. Angiographic follow-up was completed 12-months postoperatively, and there was only one case of ISR (4.35%) was observed. Postoperative stenosis of responsible vessel was significantly relieved (77.98 ± 7.69 vs. 33.85 ± 9.11), with statistically significant differences (P < 0.01). The extent of neurological deficits and effects on daily living activities at 12 months postoperatively exhibited significant improvements, as evidenced by NIHSS scores (2.40 ± 1.37 vs. 0.82 ± 0.77) and mRS scores ≤ 2 (82.0% vs. 98.0%) (P < 0.01). Cerebral perfusion improved, with no significant perioperative complications.

CONCLUSIONS: The Neuroform EZ stent is a safe and effective treatment approach for ICAS in the posterior circulation.

ABSTRACT

AIMS: Prediabetes is a public health problem, and its prevalence is increasing worldwide. Both genetic factors and lifestyle contribute to the development and progression of prediabetes. The Omentin-1 Val109Asp polymorphism is reported to be associated with insulin resistance and obesity. Moreover, research suggests that vitamin D may help decrease the risk of developing and progressing to type 2 diabetes mellitus. Therefore, this trial aimed to investigate the interaction between vitamin D supplementation and the Omentin-1 gene polymorphism on metabolic factors, omentin-1 levels and obesity values in women with prediabetes.

MATERIALS AND METHODS: This double-blind randomized controlled trial was conducted on 204 women aged 18-65 with prediabetes. After obtaining informed consent, the blood samples of all participants were analysed to determine the Omentin-1 polymorphism (Val109Asp) genotypes. The women were then randomized into intervention (n = 24) and placebo (n = 24) groups (1:1) according to each genotype of the Omentin-1 polymorphism. In total, 96 women were allocated to receive vitamin D (50 000 IU) or a placebo every two weeks for 12 weeks. Anthropometric measures, dietary intake data and physical activity level information were collected at the beginning and after the intervention. Data analyses were performed using IBM SPSS Statistics software.

RESULTS: Vitamin D administration significantly increased serum levels of 25-hydroxyvitamin D (25(OH)D), insulin, HOMA-IR, HOMA-β and QUICKI in both AT and TT genotypes (all, p < 0.001). Moreover, the serum concentration of HDL-C decreased significantly after vitamin D intervention in the AT genotype, but not in the TT genotype (p < 0.001). A significant interaction was also observed between vitamin D intervention and Omentin-1 Val109Asp polymorphism on HDL-C (p = 0.003), waist circumference (WC) (p = 0.026) and waist-to-height ratio (WHthR) (p = 0.035). However, there was no significant interplay between vitamin D and Omentin-1 polymorphism on glycaemic factors, omentin-1 levels and other lipid profiles and anthropometric measures (p ≥ 0.05).

CONCLUSIONS: The findings suggest that the Omentin-1 gene Val109Asp polymorphism may modify the effects of vitamin D intervention on serum HDL-C levels and abdominal obesity in women with prediabetes. Future clinical trials are necessary to clarify the influence of the Omentin-1 gene polymorphism genotype on the effects of vitamin D intervention.

ABSTRACT

The brain learns an internal model of the environment through sensory experiences, which is essential for high-level cognitive processes. Recent studies show that spontaneous activity reflects such a learned internal model. Although computational studies have proposed that Hebbian plasticity can learn the switching dynamics of replayed activities, it is still challenging to learn dynamic spontaneous activity that obeys the statistical properties of sensory experience. Here, we propose a pair of biologically plausible plasticity rules for excitatory and inhibitory synapses in a recurrent spiking neural network model to embed stochastic dynamics in spontaneous activity. The proposed synaptic plasticity rule for excitatory synapses seeks to minimize the discrepancy between stimulus-evoked and internally predicted activity, while inhibitory plasticity maintains the excitatory-inhibitory balance. We show that the spontaneous reactivation of cell assemblies follows the transition statistics of the model’s evoked dynamics. We also demonstrate that simulations of our model can replicate recent experimental results of spontaneous activity in songbirds, suggesting that the proposed plasticity rule might underlie the mechanism by which animals learn internal models of the environment.

ABSTRACT

BACKGROUND: The optimal methods and settings for induction of labour (IOL) in terms of effectiveness, safety, and women’s experience are still not elucidated.

OBJECTIVE: To compare the effectiveness and safety of outpatient versus inpatient cervical ripening settings for IOL.

SEARCH STRATEGY: MEDLINE, Embase, Emcare, CINAHL Plus, Scopus, Cochrane Library, WHO ICTRP and clinicaltrials.gov from inception to July 2024.

SELECTION CRITERIA: Randomised controlled trials, viable singleton gestation, no language restrictions, all the published and unpublished data.

DATA COLLECTION AND ANALYSIS: An individual participant data meta-analysis.

MAIN RESULTS: Eleven out of 18 (61.1%) eligible RCTs shared IPD, totalling 2593 pregnant individuals undergoing IOL (62.2% of all participants in the published RCTs). Among the shared RCTs, four used balloon catheters alone in both groups. Three RCTs compared outpatient balloon catheter with inpatient balloon catheter plus oxytocin. Another three RCTs compared outpatient balloon catheter to inpatient vaginal dinoprostone. One RCT used Dilapan-S in both groups. No trials evaluating outpatient use of vaginal prostaglandins were identified. Vaginal birth (11 RCTs, 2584 women, 67.8% vs. 70.2%, aOR 0.95, 95% CI 0.70; 1.30), composite perinatal outcome (9 RCTs, 2525 women, 11.1% vs. 11.7%, aOR 0.93, 95% CI 0.75; 1.16) and composite maternal (10 RCTs, 2480 women, 14.3% vs. 15.4%, aOR 0.89, 95% CI 0.65; 1.20) outcome did not differ between outpatient and inpatient groups. The outpatient group had a lower risk of acidosis, more epidural analgesia, and more oxytocin. There were no perinatal deaths in either group.

CONCLUSIONS: Overall effectiveness, perinatal and maternal safety are comparable between outpatient setting cervical ripening with a mechanical method and inpatient with any method.
