Early screening of post-stroke fall risk: A simultaneous multimodal fNIRs-EMG study.

Stroke is the third-leading cause of death and disability, and poststroke falls (PSF) are common at all stages after stroke and could even lead to injuries or death. Brain information from functional near-infrared spectroscopy (fNIRs) may precede conventional imaging and clinical symptoms but has not been systematically considered in PSF risk prediction. This study investigated the difference in brain activation between stroke patients and healthy subjects, and this study was aimed to explore fNIRs biomarkers for early screening of PSF risk by comparing the brain activation in patients at and not at PSF risk. In this study, we explored the differences in brain activation and connectivity between stroke and healthy subjects by synchronizing the detection of fNIRs and EMG tests during simple (usual sit-to-stand) and difficult tasks (sit-to-stand based on EMG feedback). Thereby further screened for neuroimaging biomarkers for early prediction of PSF risk by comparing brain activation variability in poststroke patients at and not at fall risk during simple and difficult tasks. The area under the ROC curve (AUROC), sensitivity, and specificity were used to compare the diagnostic effect. A total of 40 patients (22 not at and 18 at PSF risk) and 38 healthy subjects were enrolled. As the difficulty of standing task increased, stroke patients compared with healthy subjects further increased the activation of the unaffected side of supplementary motor area (H-SMA) and dorsolateral prefrontal cortex-Brodmann area 46 (H-DLFC-BA46) but were unable to increase functional connectivity (Group*Task: p < 0.05). More importantly, the novel finding showed that hyperactivation of the H-SMA during a simple standing task was a valid fNIRs predictor of PSF risk [AUROC 0.74, p = 0.010, sensitivity 77.8%, specificity 63.6%]. This study provided novel evidence that fNIR-derived biomarkers could early predict PSF risk that can facilitate the widespread use of real-time assessment tools in early screening and rehabilitation. Meanwhile, this study demonstrated that the higher brain activation and inability to increase the brain functional connectivity in stroke patients during difficult task indicated the inefficient use of brain resources.

Responding to suicidal behaviour in children and young people with a child maltreatment history: A scoping review

Child maltreatment affects millions of children internationally every year. Development is negatively impacted by maltreatment increasing the likelihood of maladaptive behaviours. Associations between child maltreatment and suicidal behaviour and suicide in young people has been established. However, there is a research gap in understanding effective ways to respond to and intervene with suicidal behaviour in young people who have experienced child maltreatment. A scoping review was conducted in accordance with the Joanna Briggs Institute methodology to investigate interventions that may be effective in preventing and reducing suicidal behaviours in young people who have experienced child maltreatment. Inclusion criteria were studies: (a) of children and young people who engage in suicidal behaviour and have experienced child maltreatment; (b) published in English during the time period 2000–2020; and (c) focused on responses and interventions to prevent or address suicidal behaviour. Across 37 studies, several intervention targets were identified through reflexive thematic analysis including cultivation of self-compassion, gratitude and future orientation, alleviation of depression, anxiety and post-traumatic stress disorder (PTSD) symptoms and psychological distress and addressing cognitive errors and negative views of the self. Screening and clear assessment of suicidal risk by health professionals and child welfare professionals was endorsed across studies. Several evidence-based treatments were proposed to support intervening with this client group, although only Emotional Intelligence Therapy (EIT) was empirically tested with this population. Utilisation of safe systems that the child or young person is in may be beneficial in addressing and reducing suicidal behaviour, such as inclusion of families, peers and the implementation of school-based interventions strategies. Future research is needed to empirically test and assess the effectiveness of interventions.

Foot Tumor: Comprehensive Collation and Evaluation

Background: Considerable evidence showed that foot tumors can cause severe harm to people across various age groups, though they have relatively low incidence rate. Currently, substantial research articles provide thorough discoveries among diagnosis, treatment, reconstruction, and other related areas. However, a comprehensive literature evaluation of current study findings is required. Methods: A search approach implementing the PICOS principle was utilized to acquire the literature from mainly three databases—PubMed, NCBI and SpringerLink. All the included studies underwent independent screening and evaluations of quality and risk of bias. The outcomes covered evaluation and comparison of various tumor kinds, diagnostic techniques, treatment modalities, and reconstructive procedures. Results: The location of the foot is characterized by the presence of three primary bone tumor types — osteosarcoma (OS), chondrosarcoma (CDS) and Ewing sarcoma (ES)— and four forms of soft tissue tumor—Synovial sarcoma (SS), epithelioid sarcoma (EPS), clear cell (CC) sarcoma and melanoma. Diagnosis involves the utilization of four approaches—CT, MRI, X-ray and biopsy, either singly or in combination. Out of all the options, biopsy is the most effective and accurate. Surgery and immunotherapy are widely used to treat foot tumor. The advancement of immunotherapy can significantly improve the efficiency and effectiveness of foot tumor treatment due to its specific targets and better established adjustment mechanism. Combining various types of immunotherapy with additional medicines such as chemotherapy and radiotherapy can help improve the progression of foot tumor treatment. For the reconstruction methods, Structural allograft Plastic surgery is widely used for bone tumor and soft tissue sarcoma respectively. Conclusion: The clinical significance of foot tumors is attributed to their infrequency, resulting high possibility of delayed detection and difficulties in proper treatment. The text that provides a comprehensive discussion and analysis of the diagnostic, therapeutic tactics, and repair approaches for the foot tumor can be highly beneficial to the development of foot tumor in the medical area. The methodical collation on characteristics, data of foot tumor categories is therefore equally significant. By obtaining and analyzing such information, researchers and physicians can better identify certain pattern in foot tumor. For the treatment, Immunotherapy stands out among the existing methods since it has the highest potential to selectively target certain types of foot tumors depending on their distinct needs. The evaluation of immunotherapy and reconstruction methods still contain some limitations due to the lack of the latest and adequate research.

Cancer in people who identify as lesbian, gay, bisexual, transgender, queer, or gender-nonconforming.

Individuals who identify as lesbian, gay, bisexual, transgender, queer, intersex, or gender-nonconforming (LGBTQ+) experience discrimination and minority stress that may lead to elevated cancer risk. In the absence of population-based cancer occurrence information for this population, this article comprehensively examines contemporary, age-adjusted cancer risk factor and screening prevalence using data from the National Health Interview Survey, Behavioral Risk Factor Surveillance System, and National Youth Tobacco Survey, and provides a literature review of cancer incidence and barriers to care. Lesbian, gay, and bisexual adults are more likely to smoke cigarettes than heterosexual adults (16% compared to 12% in 2021-2022), with the largest disparity among bisexual women. For example, 34% of bisexual women aged 40-49 years and 24% of those 50 and older smoke compared to 12% and 11%, respectively, of heterosexual women. Smoking is also elevated among youth who identify as lesbian, gay, or bisexual (4%) or transgender (5%) compared to heterosexual or cisgender (1%). Excess body weight is elevated among lesbian and bisexual women (68% vs. 61% among heterosexual women), largely due to higher obesity prevalence among bisexual women (43% vs. 38% among lesbian women and 33% among heterosexual women). Bisexual women also have a higher prevalence of no leisure-time physical activity (35% vs. 28% among heterosexual women), as do transgender individuals (30%-31% vs. 21%-25% among cisgender individuals). Heavier alcohol intake among lesbian, gay, and bisexual individuals is confined to bisexual women, with 14% consuming more than 7 drinks/week versus 6% of heterosexual women. Incontrast, prevalence of cancer screening and risk reducing vaccinations in LGBTQ+ individuals is similar to or higher than their heterosexual/cisgender counterparts except for lower cervical and colorectal cancer screening among transgender men. People within the LGBTQ+ population have a higher prevalence of smoking, obesity, and alcohol consumption compared to heterosexual and cisgender people, suggesting a higher cancer burden. Health systems have an opportunity to help inform these disparities through the routine collection of information on sexual orientation and gender identity to facilitate cancer surveillance and to mitigate them through education to increase awareness of LGBTQ+ health needs.

The Spectrum of Neurological Complications after Bariatric Surgery – Review of the Literature

Bariatric surgery represents one of the most efficient treatments addressing obesity and its associated complications with an increasing trend. Even if the medical benefits for patients are huge, due to weight loss and despite technical improvements in bariatric procedures, it is still associated with diverse types of complications. Most of the complications appear due to nutrient deficiency, as absorption is compromised after surgical anatomy modification. Neurological complications after bariatric surgery are very diverse with an occurrence within days to years after surgery, most frequently in patients with gastrointestinal or surgical complications. Any segment of the nervous system can be affected with distinct types of manifestations ranging from peripheral axonal neuropathy, nerve palsy secondary to compartment syndrome, encephalopathy, and myelopathy, to psychiatric and demyelinating central nervous system diseases. Identifying patients at risk and systematic screening for nutrient deficiency with proper supplementation is essential for preventing neurological complications and lifelong sequelae. In this paper, we present the spectrum of neurological complications reported after bariatric surgery.

Limitations of Separating Athletes into High or Low-Risk Groups based on a Cut-Off. A Clinical Commentary.

Athlete injury risk assessment and management is an important, yet challenging task for sport and exercise medicine professionals. A common approach to injury risk screening is to stratify athletes into risk groups based on their performance on a test relative to a cut-off threshold. However, one potential reason for ineffective injury prevention efforts is the over-reliance on identifying these 'at-risk' groups using arbitrary cut-offs for these tests and measures. The purpose of this commentary is to discuss the conceptual and technical issues related to the use of a cut-off in both research and clinical practice. How can we better assess and interpret clinical tests or measures to enable a more effective injury risk assessment in athletes? Cut-offs typically lack strong biologic plausibility to support them; and are typically derived in a data-driven manner and thus not generalizable to other samples. When a cut-off is used in analyses, information is lost, leading to potentially misleading results and less accurate injury risk prediction. Dichotomizing a continuous variable using a cut-off should be avoided. Using continuous variables on its original scale is advantageous because information is not discarded, outcome prediction accuracy is not lost, and personalized medicine can be facilitated. Researchers and clinicians are encouraged to analyze and interpret the results of tests and measures using continuous variables and avoid relying on singular cut-offs to guide decisions. Injury risk can be predicted more accurately when using continuous variables in their natural form. A more accurate risk prediction will facilitate personalized approaches to injury risk mitigation and may lead to a decline in injury rates. 5.

Short-term impact of cardiovascular screening by traditional risk assessment or coronary artery calcium score on health-related quality of life: the ROBINSCA trial.

Evidence on the impact of screening for cardiovascular diseases (CVDs) on health-related quality of life (HRQoL) is important for policy decisions about screening implementation and to uncover teachable moments to motivate healthy lifestyle choices. It is unknown whether screening by cardiac computed tomography (CT) scan has a stronger impact on HRQoL than screening by traditional risk prediction models. The study aims to investigate differences in HRQoL across the screening process between participants who were randomized to CVD risk estimation by coronary artery calcium score or Systematic COronary Risk Evaluation. A subset of 2687 ROBINSCA participants filled in questionnaires at (T0) randomization, (T1) invitation, (T2) 1-3 days before screening, (T3) 1-3 days after, and (T4) screening result. Generic HRQoL (SF-12; EQ-5D) and anxiety (STAI-6) were measured. We investigated the differences in changes in HRQoL across the screening process with linear mixed models. We found comparable levels of HRQoL at all screening moments for the two intervention groups. Mental health scores were worse at invitation and randomization than at the later time points, irrespective of screening group (all P < 0.001). A result indicating a heightened CVD risk was associated with increased anxiety in the CT screening group. Computed tomography screening for CVD risk has no detrimental impact on HRQoL and anxiety levels compared to screening by traditional risk assessment. Receiving an invitation to screenning or a result implying increased CVD risk could function as teachable moments for high-risk individuals. ROBINSCA trial registration number: NTR6471 in Dutch Trial Register (NTR).

Assessing ovarian cancer awareness and screening practices at Panjab University, Chandigarh

Objectives: Ovarian cancer (OC) poses a significant global health threat for women due to its high mortality rate and lack of reliable screening methods. It is often diagnosed at advanced stages, leading to poor outcomes. Empowering women with knowledge about risk factors and symptoms is essential for early detection and improved prognosis. Materials and Methods: A cross-sectional descriptive study was conducted among the female population of Panjab University, Chandigarh, including students, teaching, and non-teaching staff. Information on OC awareness was collected through a self-administered, structured, pretested, and validated questionnaire. Statistical analysis utilized proportions and the Chi-square test. Results: The survey revealed limited understanding of OC risk factors and symptoms among respondents. Overall awareness was low in both areas. In addition, a significant correlation was found between awareness of screening patterns and respondents’ occupations. Conclusion: There was a very poor knowledge about OC, its risk factors, symptoms, and screening patterns among females in university.

Scalability of CASCADE2001: Gis-Based Flood Risk Screening Tool to Support Watershed Master Planning

Flood risk analysis is the instrument by which floodplain and stormwater utility managers create a sound strategy and adaptation plans to reduce flood potential in their communities. As a result, there is a need to develop a flood risk screening tool to analyze watersheds and find vulnerable areas by leveraging the scientific and technological developments of the last decade to prioritize improvements. Because local municipalities are continuously challenged by the impacts of changes in precipitation and other climatic events, the screening tool needs to be scalable, while providing similar results of spatial inundation extent regardless of the scale. Likewise, the ability to perform this analysis without overwhelming limited modeling budgets is a goal for local governments who may spend large amounts of money on capital in the future to retrofit their stormwater management systems. The present study investigates the scalability of a GIS-based hydrologic-hydraulic model, CASCADE2001, to support development of watershed-based flood protection plans. The comparative analysis of the predicted flood response at three nested levels of scale were applied in south Florida to a 8-digit hydrologic unit code (HUC) level (the Caloosahatchee Watershed), a 12-digit HUC level (the Ninemile Canal Subwatershed within the Caloosahatchee Watershed), and a local municipal level (City of Clewiston, Florida within the Ninemile Canal subwatershed). The findings were that the model was scalable and the infrastructure that mattered with respect to results was driven by the scale.

IntroductionDevelopment of asthma and allergies in childhood/adolescence commonly follows a sequential progression termed the ‘atopic march’. Recent reports indicate, however, that these diseases are composed of multiple distinct phenotypes, with...

Prediction Models for HIV Infection in Infants: Analysis of Scoring Systems on Maternal, Infants, and Mode of Delivery Risk Factors.

Diagnosis for HIV in infants is hard to determine, particularly in limited- resource areas. A delay in the diagnosis of HIV-infected infants will lead to high morbidity and mortality. The purpose of this project is to construct a model of an HIV-positive infant and develop a useful and practical scoring system to estimate the likelihood of mother-to-child transmission that can be applied in the field. A cross-sectional study on 100 subjects through medical records of infants born to HIV-infected mothers was conducted at four hospitals and one community health center. Several models of risk prediction scores of HIV-infected infants were then made. Furthermore, the performed validation was performed on 20 subjects of infants born to mothers with HIV in three hospitals by comparing the scoring system and the result of the PCR RNA examination performed at the age of 6 weeks old. The risk of HIV-infected infants was higher in mothers who did not receive ARV through PMTCT programs (OR 33.6; 95% CI 4.0 to 282.2), pulmonary TB infection (OR 5.1; IK95% 1.6 to 16.0) and vaginal delivery (OR 9.2; IK95 2.2 to 38.0%). Two models can predict the occurrence of infected HIV infants effectively. Model 1 consists of maternal age, maternal ARVs, lung TB infection, gestational age, mode of delivery, and sex of the infants with sensitivity and specificity of 78.9% and 70.8% (AUC=0.817 [95% CI 0.709 to 0.926]) and likelihood ratio score of 4. Model 2 consists of ARVs to the mother, pulmonary TB infection, and mode of delivery with sensitivity and specificity of 73.7% and 86.1%; AUC value of 0.812 (95% CI 0.687 to 0.938) and likelihood ratio of 5. External Validation gave similar results to the Model 2 scoring system with PCR RNA. The prediction score of HIV-infected infants in Model 2 can be used in newborns of HIV-positive mothers as an effective and practical risk screening tool for HIV-infected infants before the gold standard examination by PCR.

Comparison of prognosis of elderly patients with gastric and colorectal tumors receiving different nutritional support treatments

Objective: To compare the prognosis of elderly patients with gastric and colorectal cancer treated with different nutritional support methods. Methods: Elderly patients with gastrointestinal tumors who received surgical treatment in Beijing Hospital from January 2019 to June 2020 were retrospectively included and divided into malnourished group and non-malnourished group according to the Global Leadership Initiative on Malnutrition (GLIM). The patients were divided into parenteral nutrition (PN) group, enteral nutrition (EN) group and enteral+parenteral nutrition (EN+PN) group according to the nutritional support. The prognosis of patients with different nutritional support treatment was compared. Results: A total of 426 elderly patients with gastric and colorectal tumors underwent surgical treatment were included, including 287 males and 139 females, aged 65-91 (72±6) years. There were 186 cases in malnourished group and 240 cases in non-malnourished group. A total of 257 patients received nutritional support therapy, including 108 cases in PN group, 48 cases in EN group and 101 cases in EN+PN group. The body mass index (BMI) of malnutrition group was lower than that of non-malnutrition group [(20.5±3.4) vs (23.7±2.8) kg/m2, P<0.001], and the score of nutritional risk screening 2002 (NRS 2002) [M (Q1, Q3)] was higher than that of non-malnutrition group [4 (4, 5) vs 2 (2, 3) points, P<0.001]. The total hospitalization time of patients in EN group was shorter than that in PN group and EN+PN group [(11.9±4.0) vs (16.5±6.5) and (19.2±7.1) d, all P<0.001]. The total hospitalization time in PN group was shorter than that in EN+PN group [(16.5±6.5) vs (19.2±7.1) d, P=0.005]. The total incidence of complications in EN group was lower than that in PN group [0 vs 9.3% (10/108), P=0.030] and EN+PN group [0 vs 19.8% (20/101), P<0.001]. The incidence of total complications in PN group was lower than that in EN+PN group [9.3% (10/108) vs 19.8% (20/101), P=0.030]. Conclusion: Among the three nutritional supportive treatment modalities: EN, PN, and EN+PN, patients receiving EN support treatment have a shorter total hospitalization time and a lower complication rate.

GLIM-defined malnutrition in patients with acute abdomen associated with poor prognosis and increased economic burden: A cross-sectional study.

The Global Leadership Initiative on Malnutrition (GLIM) criteria have rapidly developed into a principal methodological framework for nutrition diagnosis. However, the applicability of the GLIM criteria in patients with acute abdomen has not been validated. This is a cross-sectional study conducted on patients diagnosed with acute abdomen and admitted to a tertiary hospital in southwest China. Nutrition risk screening was conducted using the Nutrition Risk Screening 2002, and patients identified with nutrition risk were assessed for malnutrition based on the GLIM criteria. We enrolled a total of 440 patients with acute abdomen. The top three diagnoses of acute abdomen were intestinal obstruction (47.2%), acute appendicitis (23.1%), and digestive system perforation (8.8%). The prevalence of nutrition risk was 46.5%, with a malnutrition rate of 32.5% based on the GLIM. Patients with malnutrition according to the GLIM showed significantly higher rates of intensive care unit (ICU) admission (13.28% vs 7.07%; P = 0.003), increased hospitalization costs (median: 3315USD [interquartile range (IQR): 978-7852] vs 1641 [IQR: 816-3523] USD; P < 0.001), and longer length of hospital stay (LOS) (median: 8 [IQR: 5-13] vs 6 [IQR: 4-8] days; P < 0.001) compared with patients without malnutrition. Multivariate analysis indicated that GLIM-defined malnutrition was an independent predictor of hospitalization costs, and severe malnutrition was an independent predictor of ICU admission. GLIM criteria are applicable for diagnosing malnutrition in patients with acute abdomen. The prevalence of malnutrition was high in patients with acute abdomen. Malnutrition was associated with increased ICU admission and LOS, along with higher economic burden.

MGDA-assisted plant washing agent for improving the removal of Cd and Cu from farmland soils

Utilizing plant extracts for soil washing is a promising and cost-efficient strategy to permanently remove toxic metals from farmland soils. However, the efficiency of current plant extracts in heavy metals removal is constrained by the need of excessively high liquid-solid ratios (>10:1), which limits their practical application in the farmland soils. To address this challenge, we developed a novel binary washing agent consisting of Fructus mume residue extract (RPM) and methylglycinediacetate acid (MGDA). Through optimization experiments, we determined an optimal composition of 50 g L−1 RPM and 0.34 g L−1 MGDA (RPMG3), which exhibited a remarkable synergistic effect on the removal of Cd and Cu from two polluted farmland soils. Compared to the single use of RPM or MGDA, RPMG3 increased metal removal efficiency by 44.6%–303.8% in the alkaline dryland soil and 55.8%–141.9% in the slightly acidic paddy soil, at an optimum liquid-solid ratio of 2:1. The contents of soil Cd and Cu can be reduced to below the risk screening values via acid activation, metal ion exchange, and complexation of functional groups. Moreover, the potential ecological risks associated with Cd in the soils were significantly mitigated due to the decrease in exchangeable and reducible Cd fractions following RPMG3 washing. Additionally, RPM and RPMG3 washing led to enhancements in soil organic carbon and nutrient concentrations, as well as increased activities of soil enzymes including catalase, urease, and β-glucosidase. Notably, RPMG3 washing exhibited the most pronounced promotion effect on wheat seed germination and growth. Taken together, the binary complex of RPMG3 demonstrates potential as an environmentally friendly green washing agent capable of in reducing heavy metals from farmland soil with great efficiency, even at low liquid-solid ratios.

Strategies used by nurse leaders to support the delivery of falls prevention practices in hospitals.

Despite prevention efforts, falls in hospital are a common and ongoing safety concern, with older people more likely to fall and experience harm as a result of falls. Clinical guidelines recommend multifactorial falls risk assessment and multidomain, personalised interventions to reduce falls risks in hospitals. This article reflects on findings from a multi-site study on the implementation of multifactorial falls prevention practices that informed the development of actionable guidance. The discussion focuses on strategies used by nurse leaders, at different levels of seniority, that shaped practice on orthopaedic and older person wards. While falls risk assessment documentation was monitored routinely by senior leaders, in practice falls prevention often relied on risk screening and enhanced patient supervision. Findings suggest that nurses need to be empowered to lead practices that modify and mitigate individual falls risks where possible, with greater multidisciplinary and patient and carer involvement.

Path to Suicidality in Korean Adolescents: Mediating Role of Self-Esteem, Somatic Symptoms, and Self-Harm Amid Depressive Symptoms

This study explored the relationship between depressive symptoms and suicidality among community-dwelling adolescents aged 10–18 years, examining whether self-esteem, somatic symptoms, and self-harm mediate this relationship. Utilizing a pre-existing dataset from a nationwide adolescent mental health survey conducted in Korea in 2021, data were collected using several standardized self-administered instruments: the Korean version of Rosenberg’s self-esteem scale, Korean Children’s Somatization Inventory, Korean version of the Self-Harm Inventory, Mental Health Screening for Depressive Disorders, and Mental Health Screening for Suicide Risk. A path model was constructed and validated, followed by path analysis to assess the effects. Data from 6689 adolescents, including 5937 students and 752 out-of-school adolescents, revealed that 18.7% were in the suicidality group, 11.8% experienced depressive symptoms, 57.9% exhibited somatic symptoms, and 27.4% engaged in self-harm. Depressive symptoms had a positive direct effect on suicidality (β = 0.166, p &lt; 0.001, 95% confidence interval = 0.159–0.172). Bootstrapping tests showed a statistically significant indirect effect of self-esteem, somatic symptoms, and self-harm on the relationship between depressive symptoms and suicidality (β = 0.021, 95% confidence interval = 0.013–0.029). Our findings suggest that self-esteem, somatic symptoms, and self-harm mediate the relationship between depressive symptoms and suicidality, and comprehensive mental health management strategies addressing these factors are recommended.

Comparing suicide risk screening strategies in Spanish-speaking pediatric patients

BackgroundSuicide and suicidal behaviors pose significant global public health challenges, especially among young individuals. Effective screening strategies are crucial for addressing this crisis, with depression screening and suicide-specific tools being common approaches. This study compares their effectiveness by evaluating the Ask Suicide-Screening Questions (ASQ) against item 9 of the Patient Health Questionnaire-A (PHQ-A). MethodsThis study is a secondary analysis of the Argentinean-Spanish version of the ASQ validation study, an observational, cross-sectional, and multicenter study conducted in medical settings in Buenos Aires, Argentina. A convenience sample of pediatric outpatients/inpatients aged 10 to 18 years completed the ASQ, PHQ-A, and Suicide Ideation Questionnaire (SIQ) along with clinical and sociodemographic questions. ResultsA sample of 267 children and adolescents were included in this secondary analysis. Results show that the ASQ exhibited higher sensitivity (95.1%; 95% CI: 83% - 99%) compared to PHQ-A item 9 (73.1%; 95% CI: 57% - 85%), and superior performance in identifying suicide risk in youth. LimitationsThe study included a convenience sampling and was geographically restricted to Buenos Aires, Argentina. The study also lacked longitudinal follow-up to assess the predictive validity of these screening tools for suicide risk. ConclusionThe study highlights the ASQ's effectiveness in identifying suicide risk among youth, emphasizing the importance of specialized screening tools over depression screening tools alone for accurate risk assessment in this population.

Invasive alien plants in the Qinghai-Tibetan Plateau (China): Current state and future predictions

Invasive alien plants have received increasing attention due to their worldwide environmental impacts, ecological concerns, and significant economic consequences. The Qinghai-Tibetan Plateau is an important global biodiversity hotspot hosting rich biodiversity and serving as a crucial component of the southwest ecological security barrier, with global conservation value. However, in recent years, invasive plants have been detrimental to the conservation of biodiversity and native ecosystems on the Qinghai-Tibetan Plateau. Here, 197 invasive plant species were recognized from the Qinghai-Tibetan Plateau, encompassing 133 genera across 47 families. We used the maximum entropy model (MaxEnt) method to predict the potential distribution of invasive alien plants on the Qinghai-Tibetan Plateau. Furthermore, potential geographic distribution regions suitable for 43 invasive alien plant species were found to be primarily concentrated in central and eastern Qinghai, southern and eastern Tibet, southwest Xinjiang, and the Qinghai-Tibetan Plateau part of Sichuan, Yunnan, and Gansu in China. Notably, the current potential distribution area for all 43 invasive alien plant species accounts for 29.92 % of the total area, with an increase of 32.72–59.39 % projected by 2050. Moreover, risk screening results confirm the high risk of invasion of most alien plants on the Qinghai-Tibetan Plateau. This study provides a foundation for assessing the risks associated with introducing and managing invasive alien plants in the region. It also offers scientific support for conserving the Qinghai-Tibetan Plateau’s unique biodiversity, ecological originality, and sustainable development during economic growth.

Testing of the Czech questionnaire for identifying children at risk of obstructive sleep apnea

This study aimed to create a Czech questionnaire for pediatric obstructive sleep apnea (POSA) risk screening, a first of its kind in the Czech Republic, where options for child polysomnography are limited. Compiling items from established English questionnaires and supplementing them with additional items, we designed the first version of the Czech questionnaire and tested it in a pilot study with parents of 30 children. After pilot feedback, a revised version with dichotomous and 5-item Likert scale questions was tested on 71 children’s parents. All children (7–12 years old) underwent a home sleep apnea test to record their apnea–hypopnea index (AHI). The second (40-item) version showed high reliability (93%), with 17 items identified as the most significant. Findings from the final 17-item SEN CZ questionnaire correlated positively with AHI (p < 0.001), demonstrating 84% sensitivity, 86% specificity, and 93% reliability. Three factors, namely breathing problems, inattention, and hyperactivity (characterized by multiple items), were identified to form a higher-order factor of POSA risk, which was further supported by the correlations of their total scores with AHI (p < 0.001). The resulting SEN CZ questionnaire can serve as a tool for POSA risk screening in the Czech Republic without the need to involve medical professionals.
