Mozambique is making progress towards elimination of trachoma as a public health problem, but in some districts trachomatous inflammation-follicular (TF) prevalence remains above the 5% elimination threshold despite years of various interventions, including antibiotic mass drug administration. To characterize transmission in four districts, we incorporated testing of ocular infection and serology into routine trachoma impact surveys (TIS) in August 2022. We examined residents aged ≥ 1 year for trachoma and collected information on household water, sanitation, and hygiene. Among children aged 1-9 years, we tested conjunctival swabs for Chlamydia trachomatis nucleic acid and dried blood spots for C. trachomatis antibodies. We modeled age-dependent seroprevalence to estimate seroconversion rate (SCR). We examined 4841 children aged 1-9 years. TF prevalence ranged between 1.1 and 6.0% with three districts below the 5% threshold. PCR-confirmed infection prevalence ranged between 1.1 and 4.8%, and Pgp3 seroprevalence ranged between 8.8 and 24.3%. Pgp3 SCR was 1.9 per 100 children per year in the district with the lowest TF prevalence. Two other districts with TF

Worldwide trends to delay childbearing have increased parental ages at birth. Older parental age may harm offspring health, but mechanisms remain unclear. Alterations in offspring DNA methylation (DNAm) patterns could play a role as aging has been associated with methylation changes in gametes of older individuals. We meta-analyzed epigenome-wide associations of parental age with offspring blood DNAm of over 9500 newborns and 2000 children (5-10 years old) from the Pregnancy and Childhood Epigenetics consortium. In newborns, we identified 33 CpG sites in 13 loci with DNAm associated with maternal age (PFDR

Over the past decade, considerable progress has been made in the control, elimination, and eradication of neglected tropical diseases (NTDs). Despite these advances, most NTD programs have recently experienced important setbacks; for example, NTD interventions were some of the most frequently and severely impacted by service disruptions due to the coronavirus disease 2019 (COVID-19) pandemic. Mathematical modeling can help inform selection of interventions to meet the targets set out in the NTD road map 2021-2030, and such studies should prioritize questions that are relevant for decision-makers, especially those designing, implementing, and evaluating national and subnational programs. In September 2022, the World Health Organization hosted a stakeholder meeting to identify such priority modeling questions across a range of NTDs and to consider how modeling could inform local decision making. Here, we summarize the outputs of the meeting, highlight common themes in the questions being asked, and discuss how quantitative modeling can support programmatic decisions that may accelerate progress towards the 2030 targets.

Heritable pulmonary arterial hypertension (HPAH) is a rare progressive condition that includes patients with an identified genetic cause of pulmonary arterial hypertension (PAH). HPAH and idiopathic PAH (IPAH) have an estimated combined incidence of 0.5-0.9 cases per million children-years. Several pathogenic variants have been associated with HPAH in children and adults, including genes BMPR2, TBX4, and ACVRL1, and more rarely with variants in genes such as SOX17. HPAH is often difficult to manage and has poor prognosis despite advances in medical therapy with many patients progressing to lung transplantation, right heart failure and death. Surgical and transcatheter Potts shunt creation can reduce systolic burden and has shown reduction in morbidity and mortality in children. Early genetic testing can provide both diagnostic and prognostic value in managing and counseling children with severe PAH and it can guide transcatheter or surgical management in refractory cases despite maximal medical therapies. We describe a patient with HPAH (SOX17 mutation) who underwent percutaneous patent ductus arteriosus stent for right ventricle decompression at 2 months of age with clinical management guidance by genetic testing results.

Abstract Introduction Abdominal surgical emergencies have a high mortality rate. Effective management primarily relies on the early identification of patients at high risk of postoperative complications. The objective of our study was to determine the prognostic factors associated with poor outcomes from abdominal surgical emergencies in Senegal and to establish a predictive score for mortality for preoperative risk evaluation (NDAR (New Death Assessment Risk) score). Methodology This was a retrospective national cross-sectional study conducted over one year in 14 regions of Senegal. Adult patients (aged > 15 years) who presented with a traumatic or non-traumatic abdominal surgical emergency were included. The studied variables included clinical and paraclinical data. The variable of interest was death within 30 days of the surgery. Logistic regression was used to identify the factors independently associated with mortality. Risk factors identified after logistic regression analysis were weighted using odds ratio (OR) values rounded to the nearest whole number. The predictive capacity of the score was evaluated by analyzing the ROC (Receiver Operating Characteristic) curve based on the area under the curve (AUC). Results A total of 1114 patient records were included, with a mortality rate of 4.4%. Diagnoses were observed in patients included appendicitis in 39.8% of cases (n = 444), followed by peritonitis in 22.3% (n = 249), intestinal obstruction in 18.5% (n = 205), strangulated hernias in 10.5% (n = 117), and abdominal trauma in 6.1%. Logistic regression, established the following scores: age > 40 years (score 2), ASA status grade 2 or higher (score 1), presence of a positive QSIRS score (score 2), diagnosis of peritonitis (score 2), diagnosis of intestinal obstruction (score 1), and the presence of intestinal necrosis (score 3). The score is positive if the total is strictly greater than 5, indicating a 17.7% risk of mortality. This score had a high predictive capacity with an AUC of 0.7397. Conclusion This study enabled the establishment of a score that allows for the early identification of at-risk patients, even in constrained resource settings, facilitating appropriate perioperative management and timely surgical intervention to reduce the risk of complications. This approach, focused on early recognition of high-risk patients, is crucial for improving clinical outcomes in abdominal surgical emergencies.

Introduction: The management of gastroschisis remains problematic in low- and middle-income countries with high perioperative mortality. The objective of this work was to make an initial assessment of our management of gastroschisis. Materials and Methods: This was a monocentric and cross-sectional study including all newborns with gastroschisis between January 2017 and December 2021 in the Pediatric Surgery and Anesthesia Resuscitation Department of the Aristide Le Dantec University Hospital Center from Dakar. The socio-demographic, diagnostic, therapeutic and evolutionary parameters were studied. Results: Eighteen cases of gastroschisis (11 males and 7 females). The mothers’ mean age were 23.1 ± 5.7 years old. Only one antenatal diagnosis was made. The mean gestation age were 36.5 ± 1.5 weeks. On admission, the mean age was 16.8 ± 6.3 h and the mean weight 2244 ± 260.3 g. Gastroschisis was complex in four patients. Primary bowel reintegration was performed in 8 cases (44.4%) and progressive reintegration using an Applied Alexis retractor in 9 newborns (55.6%). Main complications were respiratory distress (28.3%) and sepsis (22.2%). The mean duration of return of oral feeding was 5.1 ± 1.9 days. Mortality was 94.4% (17/18). Conclusion: Reducing gastroschisis-related mortality in our low-income countries remains a major challenge.

Family practitioners come from many walks of life and may include students, provided they are sufficiently prepared or supported through hands-on learning experiences. In this study, we report the outcomes of community different-sex couples who participated in a free, six-week, student-facilitated Marriage Enrichment Workshop between 2015 and 2018, offered over distance via Interactive Video Conferencing. Data from n = 39 individuals (25 couples) indicated positive change during workshop participation regarding negative interaction, commitment, and sexual and emotional intimacy. At six months post-workshop, only change in negative interaction retained significance. No significant results were reported for overall marital satisfaction, and no effects of booster sessions were detected. This workshop showed slight positive gains for couples, a favorable outcome for an experience with dual goals of providing student practice and strengthening couple relationships in the community.

OBJECTIVE: To describe health equity research priorities for health care delivery systems and delineate a research and action agenda that generates evidence-based solutions to persistent racial and ethnic inequities in health outcomes. DATA SOURCES AND STUDY SETTING: This project was conducted as a component of the Agency for Healthcare Research and Qualitys (AHRQ) stakeholder engaged process to develop an Equity Agenda and Action Plan to guide priority setting to advance health equity. Recommendations were developed and refined based on expert input, evidence review, and stakeholder engagement. Participating stakeholders included experts from academia, health care organizations, industry, and government. STUDY DESIGN: Expert group consensus, informed by stakeholder engagement and targeted evidence review. DATA COLLECTION/EXTRACTION METHODS: Priority themes were derived iteratively through (1) brainstorming and idea reduction, (2) targeted evidence review of candidate themes, (3) determination of preliminary themes; (4) input on preliminary themes from stakeholders attending AHRQs 2022 Health Equity Summit; and (5) and refinement of themes based on that input. The final set of research and action recommendations was determined by authors consensus. PRINCIPAL FINDINGS: Health care delivery systems have contributed to racial and ethnic disparities in health care. High quality research is needed to inform health care delivery systems approaches to undo systemic barriers and inequities. We identified six priority themes for research; (1) institutional leadership, culture, and workforce; (2) data-driven, culturally tailored care; (3) health equity targeted performance incentives; (4) health equity-informed approaches to health system consolidation and access; (5) whole person care; (6) and whole community investment. We also suggest cross-cutting themes regarding research workforce and research timelines. CONCLUSIONS: As the nations primary health services research agency, AHRQ can advance equitable delivery of health care by funding research and disseminating evidence to help transform the organization and delivery of health care.

Abstract Background Acinetobacter baumannii is a gram-negative, opportunistic pathogen, that is responsible for a wide variety of infections and is a significant cause of hospital-acquired infections. A. baumannii is listed by the World Health Organization (WHO) as a critical priority pathogen because of its high level of antibiotic resistance and the urgent need for alternative treatment solutions. To address this challenge, bacteriophages have been used to combat bacterial infections for more than a century, and phage research has regained interest in recent years due to antimicrobial resistance (AMR). However, although the vast majority of deaths from the AMR crisis will occur in developing countries in Africa and Asia, few phages’ studies have been conducted in these regions. In this study, we present a comprehensive characterization of the bacteriophages vAbBal23 and vAbAbd25, actives against extremely drug-resistant (XDR) A. baumannii. Methods Phages were isolated from environmental wastewaters in Dakar, Senegal. The host-range, thermal and pH stabilities, infection kinetics, one step growth assay, antibiofilm activity assay, sequencing, and genomic analysis, were performed to characterize the isolated phages. Results Comparative genomic and phylogenetic analyses revealed that vAbBal23 and vAbAbd25 belong to the Caudoviricetes class, Autographiviridae family and Friunavirus genus. Both phages demonstrated activity against strains with capsular type KL230. They were stable over a wide pH range (pH 3 to 9) and at temperatures ranging from 25 °C to 40 °C. Additionally, the phages exhibited notable activity against both planktonic and biofilm cells of targeted extremely drug resistant A. baumannii. The results presented here indicate the lytic nature of vAbBal23 and vAbAbd25. This is further supported by the absence of genes encoding toxins, resistance genes and bacterial virulence factors, highlighting their potential for future phage applications. Conclusion Phages vAbBal23 and vAbAbd25 are promising biological agents that can infect A. baumannii, making them suitable candidates for use in phage therapies.

Abstract Background All-in, all-out with strict hygienic routines is necessary in modern pig production. Furthermore, a standardised, validated method is needed to quantitatively control the effect of these hygiene protocols. This study aimed to establish a reproducible and reliable sampling method to assess cleaning of the pig pen. Methods Sterilised pig faeces were mixed with indicator bacteria (i.e. Enterococcus hirae, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus) and spread out in a controlled environment. The retrieval rate of three different sampling methods were evaluated; swabbing by (i) a cloth and (ii) a sponge, analysed by standardised bacterial culture and counting of colony-forming units, and (iii) a cotton swab analysed by adenosine triphosphate (ATP) bioluminescence. Two time-points were evaluated during the study; after drying overnight and after manual scraping of the surfaces. To determine sample-to-sample variability, sampling by the cloth and the cotton swab was carried out after manual scraping and further, after high-pressure washing with cold water. Results Sampling by the cloth and the sponge showed few differences in in the number of CFU obtained before and after the manual scraping (retrieval rate), whereas the swabs, measuring ATP bioluminescence, showed a very high retrieval rate. Sample-to-sample variability was low for all three methods. Conclusions In conclusion, to sample pens for the presence of bacteria, the cloth was assessed as the preferable material, being cheap, easy, specific, and approachable, and with a low sample-to-sample variability. The ATP measurement could have potential for use when evaluating the cleaning of stables, however, threshold values for evaluating the cleaning of a pig sty needs to be developed.

Abstract Background On 5 November 2021, a fire incident following a tanker explosion occurred in the Wellington PMB Junction east of Freetown, Sierra Leone, injuring and killing people. WHO facilitated the deployment of international emergency medical teams (EMTs) to support the Ministry of Health (MoH) in providing care to the wounded in four hospitals. Objective In this study, we document Sierra Leone's experience managing the fire incident and the role of EMTs in responding to it. Method This is a cross-sectional After-Action Review (AAR) debrief of the response and deployment, including focus group discussion with WHO and MoH staff (n = 14) in a virtual workshop and document reviews on the response. The results thematically cover the event and the different agencies' responses and a review of EMTs' responses. Results At the onset of the emergency, the National Disaster Management Agency (NDMA) instituted a well-coordinated response mechanism in collaboration with the MoH and managed all response actions, such as medical services, informing partners and the public and coordinating all other agencies. WHO facilitated EMT deployments and mobilised medical supplies and equipment, while the MoH provided accommodation, logistics and coordination. The EMTs dispensed their functions with professionalism, adapted to the environment and available resources, and augmented the care the national health workers provided. They offered additional care: reconstructive surgery, pain management, palliative care, wound care, rehabilitation, physiotherapy and psychosocial counselling, which were initially inadequate at the onset of the disaster. 94 out of 157 patients were discharged home at the end. National clinicians acquired additional skills through the capacity-building activities of EMTs. The community appreciated the teams. Conclusion The government, partners and EMTs were important in the response and worked with speed and political acceptability using the context experience to provide surge support to the country. This experience brought to focus the idea of developing a national EMT in Sierra Leone, which would be useful to help respond even more swiftly. In collaboration with WHO, there is a need to institute further mechanisms to facilitate rapid response and quality-assured deployment of EMTs at regional and sub-regional levels and strengthen to support future responses.

Abstract Background Chronic overlapping pain conditions (COPCs), pain-related conditions that frequently occur together, may occur in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and could impact illness severity. This study aimed to identify comorbid COPCs in patients with ME/CFS and evaluate their impact on illness severity. Methods We used data from 923 participants in the Multi-Site Clinical Assessment of ME/CFS study, conducted in seven U.S. specialty clinics between 2012 and 2020, who completed the baseline assessment (595 ME/CFS and 328 healthy controls (HC)). COPCs included chronic low back pain (cLBP), chronic migraine/headache (cMHA), fibromyalgia (FM), interstitial cystitis/irritable bladder (IC/IB), irritable bowel syndrome (IBS), temporomandibular disorder (TMD). Illness severity was assessed through questionnaires measuring symptoms and functioning. Multivariate analysis of variance and analysis of covariance models were used for analyses. Log-binomial regression analyses were used to compute prevalence of COPCs and prevalence ratios (PR) between groups with 95% confidence intervals. Both unadjusted and adjusted results with age and sex are presented. Results 76% of participants with ME/CFS had at least one COPCs compared to 17.4% of HC. Among ME/CFS participants, cMHA was most prevalent (48.1%), followed by FM (45.0%), cLBP (33.1%), and IBS (31.6%). All individual COPCs, except TMD, were significantly more frequent in females than males. The unadjusted PR (ME/CFS compared to HC) was highest for FM [147.74 (95% confidence interval (CI) = 20.83-1047.75], followed by cLBP [39.45 (12.73-122.27)], and IC/IB [13.78 (1.88-101.24)]. The significance and order did not change after age and sex adjustment. The COPC comorbidities of cLBP and FM each had a significant impact on most health measures, particularly in pain attributes (Cohen’s d effect size 0.8 or larger). While the impact of COPC comorbidities on non-pain attributes and quality of life measures was less pronounced than that on pain, statistically significant differences between ME/CFS participants with and without COPCs were still evident. Conclusions More than 75% of ME/CFS participants had one or more COPCs. Multiple COPCs further exacerbated illness severity, especially among females with ME/CFS. Assessment and management of COPCs may help improve the health and quality of life for patients with ME/CFS.

Abstract Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system (CNS) with the immune system attacking myelin sheaths leading to neuronal death. While several disease-modifying therapies are available to treat MS, these therapies are not universally effective and do not stop disease progression. More personalized long-term treatment options that target specific aspects of the disease, such as reducing relapse frequency, delaying disability accumulation, and addressing symptoms that impact daily functioning, as well as therapies that can promote neuroprotection and repair are needed. Chimeric Antigen Receptor (CAR) Tcell therapies have revolutionized cancer treatment by intravenously (IV) administering a defined dose of T cells with high specificity provided by the CAR. An autologous CAR T cell therapy using suppressive regulatory T cells (Tregs) inducing long-lasting tolerance would be the ideal treatment for patients. Hence, we expanded the application of CAR-T cells by introducing a CAR into Tregs to treat MS patients. We developed a myelin oligodendrocyte glycoprotein (MOG)-specific CAR Treg cell therapy for patients with MS. MOG is expressed on the outer membrane of the myelin sheath, the insulating layer the forms around nerves, making it an ideal target for CAR Treg therapy. Our lead candidate is a 2nd generation CAR, composed of an anti-MOG scFv screened from a large human library. In vitro, we demonstrated CAR-dependent functionality and showed efficacy in vivo using a passive EAE mouse model. Additionally, the MOG-CAR Tregs have very low tonic signaling with a desirable signal-to-noise ratio resulting in a highly potent CAR. In summary our data suggest that MOG-CAR Tregs are a promising MS treatment option with the potential to induce long-lasting tolerance in patients.

Abstract Medication can affect the gut microbiota composition and function. The aim of this study was to investigate connections between use of common non-antibiotic medicines and the gut microbiota composition and function in a large Swedish cohort (N = 2223). Use of 67 medications and polypharmacy (≥ 5 medications), based on self-reported and prescription registry data, were associated with the relative abundance of 881 gut metagenomic species (> 5% prevalence) and 103 gut metabolic modules (GMMs). Altogether, 97 associations of 26 medications with 40 species and of four medications with five GMMs were observed (false discovery rate

Abstract Functional connectivity patterns in the human brain, like the friction ridges of a fingerprint, can uniquely identify individuals. Does this “brain fingerprint” remain distinct even during Alzheimer’s disease (AD)? Using fMRI data from healthy and pathologically ageing subjects, we find that individual functional connectivity profiles remain unique and highly heterogeneous during mild cognitive impairment and AD. However, the patterns that make individuals identifiable change with disease progression, revealing a reconfiguration of the brain fingerprint. Notably, connectivity shifts towards functional system connections in AD and lower-order cognitive functions in early disease stages. These findings emphasize the importance of focusing on individual variability rather than group differences in AD studies. Individual functional connectomes could be instrumental in creating personalized models of AD progression, predicting disease course, and optimizing treatments, paving the way for personalized medicine in AD management.

Abstract Background Out of the 21 neglected tropical diseases (NTDs) listed by the World Health Organization, 15 affect the People’s Republic of China. Despite significant achievements in controlling NTDs, comprehensive assessments of the disease burden based on actual case data and detailed information on spatial and temporal dynamics are still lacking. This study aims to assess the disease burden and spatial–temporal distribution of NTDs in China from 2005 to 2020, to provide a reference for the formulation of national health agendas in line with the global health agenda, and guide resource allocation. Methods The number of cases and deaths of major NTDs in China from 2005 to 2020 were downloaded from the China Public Health Science Data Center ( https://www.phsciencedata.cn/Share/index.jsp ) of the Chinese Center for Disease Control and Prevention and relevant literatures. Simplified formulas for disability-adjusted life years (DALYs) helped estimate the years of life lost (YLLs), years lived with disability (YLDs), and total DALYs. Spatial autocorrelation analysis of the average NTDs burden data for the years 2005 to 2020 was evaluated using Moran's I statistic. Results China's overall NTDs burden decreased significantly, from 245,444.53 DALYs in 2005 to 18,984.34 DALYs in 2020, marking a reduction of 92.27%. In 2005, the DALYs caused by schistosomiasis and rabies represent a substantial proportion of the total disease burden, accounting for 65.37% and 34.43% respectively. In 2015, Hunan and Sichuan provinces had the highest diversity of NTDs, with 9 and 8 number of different NTDs reported respectively. And the highest disease burden was observed in Sichuan (242,683.46 DALYs), Xizang Zizhiqu (178,318.99 DALYs) and Guangdong (154,228.31 DALYs). The “high-high” clustering areas of NTDs were mainly in China's central and southern regions, as identified by spatial autocorrelation analysis. Conclusions China has made unremitting efforts in the prevention and control of NTDs, and the disease burden of major NTDs in China has decreased significantly. Using the One Health concept to guide disease prevention and control in the field to effectively save medical resources and achieve precise intervention. Graphical abstract

Mineral identification and quantification are key to the understanding and, hence, the capacity to predict material properties. The method of choice for mineral quantification is powder X-ray diffraction (XRD), generally using a Rietveld refinement approach. However, a successful Rietveld refinement requires preliminary identification of the phases that make up the sample. This is generally carried out manually, and this task becomes extremely long or virtually impossible in the case of very large datasets such as those from synchrotron X-ray diffraction computed tomography. To circumvent this issue, this article proposes a novel neural network (NN) method for automating phase identification and quantification. An XRD pattern calculation code was used to generate large datasets of synthetic data that are used to train the NN. This approach offers significant advantages, including the ability to construct databases with a substantial number of XRD patterns and the introduction of extensive variability into these patterns. To enhance the performance of the NN, a specifically designed loss function for proportion inference was employed during the training process, offering improved efficiency and stability compared with traditional functions. The NN, trained exclusively with synthetic data, proved its ability to identify and quantify mineral phases on synthetic and real XRD patterns. Trained NN errors were equal to 0.5% for phase quantification on the synthetic test set, and 6% on the experimental data, in a system containing four phases of contrasting crystal structures (calcite, gibbsite, dolomite and hematite). The proposed method is freely available on GitHub and allows for major advances since it can be applied to any dataset, regardless of the mineral phases present.

ABSTRACT: Freestall comfort is reflected in various indicators, including the ability for dairy cattle to display unhindered posture transition movements in the cubicles. To ensure farm animal welfare, it is instrumental for the farm management to be able to continuously monitor occurrences of abnormal motions. Advances in computer vision have enabled accurate kinematic measurements in several fields, such as human, equine, and bovine biomechanics. An important step upstream to measuring displacement during posture transitions is determining that the behavior is accurately detected. In this study, we propose a framework for detecting lying-to-standing posture transitions from 3-dimensional (3D) pose estimation data. A multiview computer vision system recorded posture transitions between December 2021 and April 2022 in a Swedish stall housing 183 individual cows. The output data consisted of the 3D coordinates of specific anatomical landmarks. The sensitivity of posture transition detection was 88.2%, and precision reached 99.5%. In analyzing those transition movements, breakpoints detected the timestamp of onset of the rising motion, which was compared with that annotated by observers. Agreement between observers, measured by intraclass correlation, was 0.85 between 3 human observers and 0.81 when adding the automated detection. The intra-observer mean absolute difference in annotated timestamps ranged from 0.4 s to 0.7 s. The mean absolute difference between each observer and the automated detection ranged from 1.0 s to 1.3 s. We found a significant difference in annotated timestamps between all observer pairs, but not between the observers and the automated detection, leading to the conclusion that the automated detection does not introduce a distinct bias. We conclude that the model is able to accurately detect the phenomenon of interest and that it is equitable to an observer.

Grounding this study in Bronfenbrenner's ecological framework, the authors used a survey that includes psychometrically sound measures, to investigate the social experiences of 54 immigrant families with young children and the factors that shape their perceptions of life satisfaction and social support in a highly urban city. Results show persistent challenges related to discrimination and access to resources. Despite these challenges, participants' overall satisfaction with life was rated high and positively correlated with their comfort with practicing their culture and with their perceived social support. Implications involve the need to design evidence-based policies and programmes that promote immigrant families' wellbeing.

Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n = 340; 39% female) into subgroups based on their word reading and vocabulary knowledge. Growth models were then fit within each profile to evaluate reading comprehension performance over time. Results: Analyses revealed four latent profiles emerged: (a) very low word reading and low vocabulary (10%), (b) low word reading and low vocabulary (71%), (c) average word reading and low vocabulary (16%), and (d) high word reading and low vocabulary (3%). Subgroups varied in their reading comprehension initially and over one year. Students in the subgroup marked by very low word reading and low vocabulary showed the lowest reading comprehension performance initially; however, they also showed the greatest growth over one year. Conclusion: These findings suggest that there is heterogeneity in the reading skill profiles of Spanish-speaking EBs with reading comprehension difficulties. They also underscore the prevalence of word reading difficulties among these students. These may be important factors to consider when developing interventions to prevent and remediate these difficulties.

This study examined the relations between reading anxiety, general anxiety, and test anxiety in a sample of students with reading difficulties (n = 536). It also tested if dimensions of anxiety were differentially related to word reading accuracy and fluency, text reading fluency, or reading comprehension. The results indicated that the three anxiety measures were significantly related (r = 0.51 to 0.56, p < 0.001). Additionally, higher reading anxiety was related to poorer word reading fluency, text reading fluency, and comprehension outcomes. Further analyses indicated that these relations existed in students who fell in the middle and upper quantiles for reading, but not the lowest quantile. This pattern of findings suggests that the relation is complex and varies depending on severity of reading difficulty. Results may help to inform future efforts to support students with reading difficulties, including students with dyslexia.

Background: Adolescent substance use is often associated with concurrent mental health problems (e.g., depression, suicide attempts, parental emotional and physical abuse, not feeling close to people at school, and lower virtual connectedness) at multiple ecological levels. Objective: This study examined whether such risk factors among adolescents were associated with the use of telemental healthcare (TMHC) and whether gender moderated these associations. Methods: Data were drawn from the Adolescent Behaviors and Experiences Survey, collected by the U.S. Centers for Disease Control and Prevention from January to June 2021. A hierarchical multiple logistic regression analysis was conducted using a national sample of 1,460 students in Grades 9-12 in the United States who reported having used more alcohol and/or drugs during the pandemic than before it started. Results: The results showed that only 15.3% of students sought TMHC. Students reporting increased substance use during the pandemic were more likely to use TMHC if they experienced more severe mental health problems (e.g., suicide attempts) compared to other ecological factors, such as issues with their family, school, or community. Analysis of the moderating effect showed that the closer male students felt to people at school, the more likely they were to seek TMHC, whereas the opposite was true for female students. Conclusions: The findings highlighted that feeling close to people at school is an important aspect of understanding the help-seeking behavior of female and male adolescent substance users.

An inferential comprehension intervention addressing reading comprehension difficulties of middle schoolers was tested. Method Students in Grades 6 to 8 (n = 145; 53.8% female; 71% White; 24% Black) who failed their state literacy test, were randomly assigned to tutor-led, computerized, or business-as-usual [BaU] interventions. Results The tutor-led intervention produced significant effects compared to BaU (g = 0.40) and computer-led (g = 0.30) on inference types instructed in the intervention. Students with adequate word reading in tutor-led gained more compared to BaU on WIAT-III Reading Comprehension. Boys gained more from tutor-led and BaU vs. computer-led on several measures. Conclusion Inferential comprehension is malleable in middle school, but adequate word reading may be important. The effects for boys vs. girls suggest the need to understand intervention factors beyond the content and instructional procedures of interventions. Findings are discussed with reference to theories of inference and reading comprehension as well as the literature on technology-aided literacy interventions.
