The likely increase in the frequency and severity of droughts with climate warming will pose an enormous challenge for the conservation of forest biodiversity. Documenting the response of species to recent droughts can inform future conservation actions. Mammals that breed and mature slowly may be especially vulnerable to drought-induced disruption to breeding. The yellow-bellied glider (Petaurus australis, Shaw) is a threatened low-density, arboreal marsupial of eastern Australia. Following a severe drought in 2019, one population had declined by 48% by 2021. The present study investigated whether this population had recovered 3–4 years (2022 and 2023) after that drought. Audio surveys of this highly vocal species were conducted at 42 sites, sampling > 1000 h per year, and producing recordings of 2038–2856 call sequences. The probability of occupancy varied little across the two survey years (0.92–0.97). Local abundance in 2023 had returned to pre-drought levels (45% of occupied sites had ≥3 individuals compared to 6% in 2021). These findings show a recovery from a drought-induced decline required at least 3 years, in keeping with the slow life history traits of this species. This study highlights the importance of considering a species’ life history strategy when evaluating its sensitivity to drought. Full article

Background and Objectives: Thailand’s demographic shift toward an aging population increases vulnerability among older adults to the long-term mental health effects of childhood trauma. While childhood adversity is linked to heightened risks of late-life depression and PTSD, the moderating role of resilience remains underexplored in Thai older adults. This study investigated whether resilience moderates the association between childhood trauma and depressive or PTSD symptoms in this population. Materials and Methods: A cross-sectional survey was conducted with 201 older patients (mean age 68.6 years) from the Family Medicine and Geriatric Psychiatry Clinics at Maharaj Nakorn Chiang Mai Hospital. Participants completed validated measures on trauma history, resilience, depression, and PTSD symptoms. A moderation analysis was performed, adjusting for covariates including education, family support, and psychiatric history. Results: The findings revealed that resilience significantly buffered the impact of childhood trauma on depression but did not mitigate PTSD symptoms. Conclusions: These results underscore the protective role of resilience against depression following childhood trauma in older adults, yet also point to its limitations in alleviating trauma-specific responses such as PTSD. This study highlights the need for trauma-informed geriatric mental health strategies and calls for further research on resilience, focusing on cultural context and adaptive mechanisms, including emotion regulation and social connectedness, in older populations.

Emerging infectious diseases such as chytridiomycosis and ranavirosis, caused by Batrachochytrium dendrobatidis (Bd) and ranavirus (RV), respectively, are major contributors to global amphibian declines. Despite their significance, comprehensive data on the spatial epidemiology of these pathogens in South Korea remain limited. This study aimed to assess the nationwide co-occurrence and prevalence of Bd and RV across four anuran species in five administrative regions. Infection rates were analyzed in relation to host species, sex, and life history stage. Results indicated distinct prevalence patterns driven by ecological traits. Bd was predominantly detected in mountainous and coastal habitats, whereas RV was more common in flat inland areas. Both pathogens exhibited peak occurrence in central regions, likely reflecting seasonal transmission dynamics rather than stable endemic hotspots. The observed spatial heterogeneity appears to be influenced by pathogen-specific thermal tolerance and host ecology. These findings underscore the importance of understanding host–pathogen–environment interactions for effective disease surveillance and management. Continuous monitoring and integrative ecological approaches are essential to mitigate pathogen-induced biodiversity loss and to inform amphibian conservation strategies in East Asia. Full article

Over the past three turbulent decades, research has profoundly reshaped our understanding of chronic Toxoplasma gondii infection—traditionally regarded as harmless in immunocompetent individuals—unveiling its surprising impact on human health, performance, and behavior. This review emphasizes the effects of chronic Toxoplasma infection on physical and mental health, cognitive performance, and behavioral changes, highlighting key findings from studies investigating these domains, with a particular focus on both ultimate and proximate mechanisms underlying the observed effects. To this end, the primary focus will be on human studies; however, animal model studies will also be thoroughly considered when necessary and appropriate, to provide context and additional important information. Research demonstrates that chronic Toxoplasma infection may contribute to a broad spectrum of physical health issues. Ecological studies have revealed correlations between toxoplasmosis prevalence and increased morbidity and mortality from various conditions, including cardiovascular diseases, neurological disorders, and certain cancers. Large-scale cross-sectional studies have further shown that infected individuals report a higher incidence of numerous health complaints and diagnosed diseases, suggesting a significant impact on overall physical well-being. In addition to physical health, lifelong Toxoplasma infection (subclinical toxoplasmosis) has been implicated in cognitive impairments and behavioral changes. Studies have reported associations between infection and poorer performance in areas such as reaction time, processing speed, working memory, and executive function. Many of these behavioral changes likely relate to worsened health and a shift towards a “fast life history strategy.” These cognitive deficits can have significant implications for daily functioning and performance. Furthermore, the role of Toxoplasma infection in the development or exacerbation of mental health disorders has been extensively investigated. Meta-analyses, ecological studies, and large-scale observational studies have demonstrated associations between Toxoplasma infection and an increased risk of disorders such as schizophrenia and obsessive–compulsive disorder. While the precise mechanisms underlying these associations remain under investigation, research suggests that neuroinflammation and alterations in neurotransmitter systems are likely to play a role. Far from being harmless, subclinical toxoplasmosis is increasingly recognized as a hidden factor influencing human health, behavior, and cognitive performance—with implications that extend well beyond the individual to public health at large. Further research is warranted to elucidate the complex interplay between Toxoplasma infection, host physiology, and the development of various physical, cognitive, behavioral, and mental health conditions.

Background and Objectives: Chronic pain (CP), defined as pain persisting for over 3 months, is a significant cause of global disability and affects more than 20% of individuals in Western countries, including Italy. Substantial evidence indicates a higher prevalence of CP among women, who also experience greater sensitivity, increased frequency, and a longer duration of pain. The impact of CP on quality of life, daily functioning, and employment is profound, particularly for women. However, chronic pain research has insufficiently addressed sex and gender differences, contributing to suboptimal and inequitable care. This neglect limits the development of personalized treatment strategies and, when combined with an aging population and women’s longer life expectancy, highlights an increasing societal and economic burden. Materials and Methods: The authors conducted a narrative review of studies examining biological, psychological, or social determinants of sex-related differences in CP perception or treatment. Each thematic area was reviewed by at least two authors, who critically appraised the literature. Their analyses were refined through iterative group discussions to develop concise, evidence-informed recommendations for personalized and equitable pain management. Results: Sex differences in CP arise from a range of factors, including biological mechanisms such as hormonal and genetic influences, psycho-social factors such as depression and anxiety, and socio-economic determinants, such as income and education levels. These factors also affect sex-specific outcomes of analgesic treatments currently available. Identifying these risk factors and tailoring treatment strategies to sex differences can significantly improve CP management. Such a personalized approach is essential for advancing precision medicine in CP management. Even in the absence of molecular or genomic biomarkers, adopting a biopsychosocial model that considers sex and gender differences, symptoms, physiological indicators, medical history, lifestyle, and psychological aspects may substantially enhance patient outcomes. Conclusions: This review provides a comprehensive analysis of sex differences in CP perception, stressing the importance of individualized, interdisciplinary approaches in pain management. Addressing both the biological and psycho-social contributors to pain in men and women is critical for guiding healthcare professionals in implementing precision pain medicine strategies, ultimately fostering more equitable and effective care.

The age-based life history of two commercially important parrotfishes (Labridae: tribe Scarinae) and one goatfish (Mullidae) were characterized based on the commercial nearshore fishery in Saipan, Commonwealth of the Northern Mariana Islands. Age, growth, reproduction, and mortality were derived from fishery-dependent samples using sagittal otoliths and gonads for the stareye parrotfish Calotomus carolinus, pacific bullethead parrotfish Chlorurus spilurus, and yellowfin goatfish Mulloidichthys vanicolensis. All three species had short lifespans of 10 years or less, with a maximum age of 4 years for C. carolinus, 10 years for C. spilurus, and 7 years for M. vanicolensis. All three species had a fast initial growth to terminal body sizes, early maturation, and spawned throughout the year. The age-based demographic information presented here can be used to inform future stock assessments, fisheries management, and population models. Full article

Rectal cancer management necessitates a rigorous multidisciplinary strategy, emphasizing precise staging and detailed risk stratification to inform optimal therapeutic decision-making. Obtaining an accurate histological diagnosis before initiating treatment is essential. Comprehensive staging integrates clinical evaluation, thorough medical history analysis, assessment of carcinoembryonic antigen (CEA) levels, and computed tomography (CT) imaging of the abdomen and thorax. High-resolution pelvic magnetic resonance imaging (MRI), utilizing dedicated rectal protocols, is critical for identifying recurrence risks and delineating precise anatomical relationships. Endoscopic ultrasound further refines staging accuracy by determining the tumor infiltration depth in early-stage cancers, while preoperative colonoscopy effectively identifies synchronous colorectal lesions. In early-stage rectal cancers (T1–T2, N0, and M0), radical surgical resection remains the standard of care, although transanal local excision can be selectively indicated for certain T1N0 tumors. In contrast, locally advanced rectal cancers (T3, T4, and N+) characterized by microsatellite stability or proficient mismatch repair are optimally managed with total neoadjuvant therapy (TNT), which combines chemoradiotherapy with oxaliplatin-based systemic chemotherapy. Additionally, tumors exhibiting high microsatellite instability or mismatch repair deficiency respond favorably to immune checkpoint inhibitors (ICIs). The evaluation of tumor response following neoadjuvant therapy, utilizing MRI and endoscopic assessments, facilitates individualized treatment planning, including non-operative approaches for patients with confirmed complete clinical responses who comply with rigorous follow-up. Recent advancements in molecular characterization, targeted therapies, and immunotherapy highlight a significant evolution towards personalized medicine. The effective integration of these innovations requires enhanced interdisciplinary collaboration to improve patient prognosis and quality of life. Full article

Background: The Mediterranean diet is considered one of the healthiest and safest diets for preventing chronic diseases. The primary objective of this study was to assess the association between adherence to the Mediterranean diet and the occurrence of prediabetes in a representative population of Bialystok, Poland. Prediabetes is a condition characterized by elevated blood glucose levels that are higher than normal but not yet in the diabetic range, indicating an increased risk of developing type 2 diabetes. Methods: The study participants were selected into healthy control (HC) and prediabetic (PreD) groups based on age and gender. Biochemical measurements included total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), fasting glucose (FG), glycated hemoglobin (HbA1c), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6). Additionally, blood pressure, handgrip strength, anthropometric parameters, and body composition were measured. Information on patients’ social data, medical history, and lifestyle history was collected using questionnaires developed for this study. A standardized questionnaire, the Satisfaction with Life Scale (SWLS), was used to assess life satisfaction. Dietary total antioxidant capacity (DTAC) and dietary total polyphenol intake (DTPI) were determined using a 3-day nutritional interview and appropriate databases containing information on polyphenols and the antioxidant potential of food products. To assess adherence to the Mediterranean diet recommendations, a 9-item Mediterranean Diet Index (MDI) was used. Results: It was found that the mean MDI for the entire group was low (3.98 ± 1.74), and the HC was characterized by a significantly higher MDI compared to the PreD. A statistically significant positive correlation was found between MDI and HDL-C, whereas a negative correlation was found between MDI and FG, homeostatic model assessment for insulin resistance (HOMA-IR), diastolic blood pressure (DBP), IL-6, body mass index (BMI), waist-hip ratio (WHR), waist circumference, visceral fat mass, android/gynoid fat ratio. Conclusions: Abdominal obesity was shown to significantly reduce life satisfaction. In model 3, after adjusting for age, sex, dietary energy intake, alcohol consumption, and smoking, each additional MDI point indicated a 10% lower risk of prediabetes. Full article

Muehlenbeckia tuggeranong is an endangered subshrub with an estimated seven individuals remaining in its native habitat, and twelve held in an ex situ living collection in the Australian National Botanic Gardens, Canberra. We conducted a genetic analysis on all known individuals of the species both in situ and ex situ to inform the conservation management of one of the rarest plants in Australia, certainly the rarest in the Australian Capital Territory. We found recent seedlings did not result from hybridisation with M. axillaris but resulted from sexual reproduction within the ex situ collection, leading to greater genetic diversity ex situ than in situ. However, low genetic diversity across the species indicates a high risk of extinction. Through simulations we identified the optimal breeding pairs to minimise further genetic diversity loss and increase the number of available genotypes for future reintroduction. Our work highlights the need to incorporate genetically informed breeding programs into living collections management of endangered plant species, particular those with unique life history traits.

Diversion programs are increasingly used as alternatives to criminal penalties for women involved in commercial sex, yet limited research has examined how such programs support behavior change across diverse subgroups, particularly between sex-trafficked and non-trafficked participants. This study evaluates changes in readiness for change among 131 women who participated in a court-ordered diversion program led by survivors of sex trafficking. Participants were classified as sex-trafficked or non-trafficked based on self-reported age of entry and experiences of third-party control. The program offered a range of trauma-informed services aimed at fostering holistic well-being and facilitating a pathway out of sex trafficking and prostitution. Participants engaged in group classes focused on job interview skills, emotion regulation, substance use awareness, and psychoeducation related to trauma. Life skills workshops addressed financial literacy, relationship dynamics, and conflict resolution. In addition, participants received referrals to GED programs, career training, mental health services, and emergency housing as needed. Program duration typically ranged from 12 to 16 weeks, adjusted for individual needs. Results from a repeated-measures Analysis of Variance (ANOVA) revealed a significant increase in readiness for change (p < 0.05) from program entry to completion. However, women with trafficking histories demonstrated smaller gains than their non-trafficked peers, suggesting that trauma-related and systemic barriers may limit the impact of short-term interventions. These findings underscore the importance of tailoring diversion programs to address the complex needs of sex-trafficked individuals and support the development of differentiated trauma-responsive strategies within diversion frameworks.

Introduction: The clinical syndrome of heart failure (HF) is progressive and disabling for patients who rely on their caregivers for help and support. The caregiving role is inducing major changes in the personal, social, and family life of caregivers and entails a heavy emotional and physical burden, which in turn negatively affects their quality of life (QoL). Purpose: The purpose of this study was to explore the QoL of caregivers of patients with HF as well as the associated caregivers’ and patients’ characteristics. Material and Methods: The sample of the study included 340 caregivers along with their hospitalized patients. Data collection was performed by the method of the interview using the questionnaire “SF-36 Health Survey (SF-36)” to assess caregivers’ QoL. Results: Τhe physical QoL component of caregivers was found to be statistically significantly associated with the type of relationship with their patient (p = 0.001), age (p = 0.001), level of education (p = 0.001), occupation (p = 0.001), information about HF patients (p = 0.001), worry about finances (p = 0.001), and insecurity about the future (p = 0.001). The mental QoL component of caregivers was found to be statistically significantly associated with the type of relationship with their patient (p = 0.001), gender (p = 0.009), age (p = 0.001), level of education (p = 0.001), occupation (p = 0.001), frequency of visits to hospitalized patient (p = 0.001), information about HF (p = 0.029), anxiety about patients’ self-care (p = 0.001), worry about finances (p = 0.001), and insecurity about the future (p = 0.001). In terms of HF patient’s characteristics, the physical QoL component of caregivers was found to be statistically significantly associated with the patients’ age (p = 0.001), patients’ education level (p = 0.001), patients’ occupation (p = 0.006), patients’ family history of cardiac disease (p = 0.006), and patients’ self-reported symptom management before hospital admission (p = 0.022). The mental QoL component of caregivers was found to be statistically significantly associated with the patients’ education level (p = 0.020), the patients’ NYHA stage (p = 0.001), prior hospitalization (p = 0.001), the patients’ family history of cardiac disease (p = 0.012), and the patients’ self-reported symptom management before admission (p = 0.001). Conclusions: In-depth understanding factors affecting QoL in caregivers with HF may enhance plans and actions to attain healthcare goals among societies globally. Full article

Background/Objectives: The consumption of highly processed foods (HPFs) is increasing on a global scale, and these foods have been associated with non-communicable diseases (NCDs). In particular, the consumption of HPFs has been associated with the intensification of inflammatory responses, with these foods being implicated in the exacerbation of chronic inflammatory conditions. Conversely, ultra-processed foods (UPFs) have been indicated as a possible factor in the pathogenesis of inflammatory bowel disease (IBD), particularly Crohn’s disease (CD). Methods: From October 2023 to October 2024, 275 patients with IBD were screened at a tertiary referral center. This study’s control cohort comprises 101 individuals from the local population. All study participants answered a questionnaire asking about the participants’ sex, body type and weight, height, age, marital status, employment, and other sociodemographic information. All subjects had to complete a food frequency questionnaire (FFQ) and the German version of the Screening Questionnaire of Highly Processed Food Consumption (sQ-HPF). IBD patients answered questions about their disease course and history as well as objective parameters of inflammation have been collected. Results: The sQ-HPF (%) showed significant differences (p < 0.001; g = −0.5) between the IBD cohort and the control group, suggesting higher HPF consumption within the IBD cohort. A subsequent analysis of the IBD cohort found no significant difference by disease type (Crohn’s disease: p = 0.441; g = −0.1; ulcerative colitis: p = 0.170; g = −0.3) or sex (women: p = 0.219; g = 0.2; men: p = 0.522; g = 0.1), but men with colitis did show higher HPF% compared to women with the same diagnosis. Spearman’s rho revealed no significant correlation between fecal calprotectin and HPF% in men with CD (p = 0.155, r = 0.191) or women with CD (p = 0.836, r = 0.026), and no correlation in men with UC (p = 0.707, r = 0.057) or women with UC (p = 0.560, r = −0.099). IBD health-related quality of life showed a significant positive correlation with HPF consumption in CD men (p = 0.026, r = 0.278), but not in CD women (p = 0.539, r = 0.075). No significant correlations between HPF consumption and health-related quality of life have been found in UC (men: p = 0.663, r = −0.064; women: p = 0.445, r = 0.121). Conclusions: The German version of the sQ-HPF is a reliable tool for rapid screening of habitual HPF% consumption in IBD patients. The findings of this analysis indicate a clear deviation from the recommended nutritional regimens for IBD, emphasizing the imperative for further investigation and the potential development of interventions to address these dietary discrepancies, with the ultimate goal of optimizing health outcomes for these patients.

Background/Objectives: Women of color remain at risk of new HIV diagnoses. This study applied an intersectional framework to explore the lived experiences of women of color aged 50 and older who are living and aging with HIV. Methods: The researcher conducted a secondary analysis of data from a study involving respondents aged 50 years or older living with HIV. The mean age of the female participants (N = 12) was 57.42 (SD = 5.18, range = 47–65). Ecological Systems Theory was used to operationalize intersectionality, considering participants’ multiple identities and social locations. Results: Participants described histories of role enactment and struggles as they faced structural, community, and interpersonal violence, anticipatory loss, and shame. Their narratives highlighted how layered oppressions shaped their experiences across the life course. Conclusions: Findings underscore the importance of using intersectional theoretical frameworks to examine the intersecting systems of oppression affecting older women of color living with HIV. The study recommends trauma-informed assessments and interventions, as well as culturally informed clinician training rooted in evidence-based practices. Full article

Tokyo Bay is one of the busiest ocean areas for human activity worldwide, characterized by a high density of maritime traffic and industrial development. This area is also recognized as the habitat of the narrow-ridged finless porpoise, an endangered toothed whale. Although the existence of this species has been recognized, its scientific data, such as population size and geographic distribution, are limited in the region. Therefore, using social media, we initiated a research project to collect sighting information on this species in Tokyo Bay. As a result, 27 valid pieces of information on the finless porpoises were collected from July 2024 to the end of February 2025. The sightings were reported mainly in the waters north of Futtsu Cape, indicating that this species is localized in the northern part of Tokyo Bay. Also, most of the reported sightings were of groups of wo or more animals. Notably, a school of at least 30 animals was recorded, marking the most prominent school ever observed in the region and the third largest in Japan. This study highlights the importance of the northern region of Tokyo Bay as a habitat for this species. The effective integration of citizen science with scientific and quantitative research will enhance our understanding of the life history of this endangered species, thereby supporting conservation efforts.

Chlorantraniliprole, serving as a substitute for traditional insecticide, has been widely utilized in controlling lepidopteran pests. Loxostege sticticalis (Lepidoptera: Crambidae) is a polyphagous insect and poses a significant threat as a migratory insect. This study investigated the life history traits of a field-collected population in response to chlorantraniliprole exposure based on an age-stage, two-sex life table. After treating the third-instar larvae of L. sticticalis with three different doses of chlorantraniliprole, namely LC₁₀, LC₂₅, and LC₅₀, the survival, development, and fecundity of L. sticticalis were affected significantly in a dose-dependent manner. Chlorantraniliprole at doses of LC₁₀, LC₂₅, and LC₅₀ prolonged the average generation time (T) compared to the control group. The net reproductive rate (R₀) and intrinsic growth rate (r) were significantly higher in the LC₁₀ group but significantly lower in the LC₂₅ and LC₅₀ groups. Chlorantraniliprole used at a dose of LC₁₀ was shown to increase the finite growth rate (λ), while it decreased λ at doses of LC₂₅ and LC₅₀. These results suggested that chlorantraniliprole induces hormetic effects by enhancing fecundity and reproductive potential at lower sublethal concentration (LC₁₀), while reducing the reproductive output at higher doses (LC₂₅ and LC₅₀). Our results provide useful information for developing management strategies for L. sticticalis involving the use of chlorantraniliprole. Full article
