Although the needs of conflict-affected children are well-documented, research on the post-conflict period is limited, particularly in Syria, where the fall of the Assad regime has created a rapidly evolving environment for internally displaced children. This study explores how key informants perceive the mental health needs, daily stressors and coping strategies of internally displaced children during the post-regime period. Online semi-structured interviews were conducted with 10 staff members from a non-governmental organization working in psychosocial support in the Syria camps. Data were analyzed using thematic analysis. Five major themes emerged: (1) stressors in the current camp environment, (2) challenges related to return, (3) observed emotional and behavioral difficulties, (4) children’s psychological resources and (5) needs and gaps in support services. Findings highlight the inseparability of children’s mental health from basic needs, the role of place-based attachments in return processes and the importance of a holistic approach that considers context-specific stressors and resources in this unique period.
The family Camallanidae includes nematodes traditionally classified based on the morphology of their buccal capsules. However, several questions have been raised about the validity of these characteristics for their classification. Despite having a remarkable diversity, our knowledge of camallanids in Brazil remains limited, leaving gaps in our understanding of the true species diversity in the country, their geographical distribution and host species associations. Therefore, this study presents a checklist of species in the family Camallanidae recorded in Brazil, including a review for the classificationa and new dichotomous key for identifying the genera. Camallanidae comprises 2 subfamilies with 13 valid genera, classified based on the morphology of the buccal capsule and trident, and on the presence, shape and distribution of internal ridges on the capsule. Thirty-seven species, distributed across 7 genera, have been recorded in Brazil so far, parasitizing 276 host taxa, including fish, chelonians and snakes, with no records of these nematodes parasitizing amphibians in the country. We reallocated five species of Spirocamallanus and 2 species of Procamallanus to Denticamallanus, and 1 species of Camallanus was reallocated to Serpinema. Spirocamallanus is the most diverse genus, with 16 species, and Spirocamallanus inopinatus exhibited the highest host taxa association diversity (144) and the widest geographical distribution. Until further molecular studies are conducted, the new dichotomous key presented in this checklist contributes to a better understanding of the classification of the family Camallanidae, based on the morphology of the buccal capsule and accessory structures.
Human strongyloidiasis, caused by Strongyloides stercoralis, is a neglected disease of high worldwide prevalence, with considerable potential for severe, fatal outcomes in complicated cases. Studies using the rodent parasite Strongyloides venezuelensis as a model have provided valuable insights into strongyloidiasis, yet efficient, standardised methods for isolating large quantities of viable parasite eggs for biomedical research remain scarce. This study revisits and modernises the classical flotation principle, presenting a saturated-solution centrifugation protocol for egg recovery from infected clawed jirds (Meriones unguiculatus). Saturated NaCl outperformed sucrose, primarily due to enhanced egg visualisation and reduced microbial contamination, achieving mean recovery of 84.8 ± 6.7% (peaks to 94%). Key variables – including faecal suspension volume, solution concentration, reprocessing, and the NaCl gradient – were systematically optimised to maximise recovery and viability. The resulting protocol is cost-effective, rapid, and practical, enabling scalable collection of viable S. venezuelensis eggs (and likely other nematodes) for different applications, including hatching studies, larval development, microenvironmental assays, and drug screening. By integrating classical diagnostics with parametric optimisation, this study exemplifies how methodological advances preserve and renew foundational knowledge, underscoring its epistemological value in experimental parasitology.
The families of cancer patients experience many forms of distress, as a result of their loved one’s cancer diagnosis. However, there have been no reports of suicide attempts of caregivers directly linked to the diagnosis of advanced cancer in a family member.
Methods
We reported a caregiver who attempt suicide two months after his wife was diagnosed with advanced cancer.
Results
The subject was a 69-year-old male who had been caring for his wife, diagnosed with advanced stomach cancer, for two months. The patient’s husband, acting as her caregiver, was referred by his wife (a cancer patient) to meet with a nurse. He reported insomnia and a desire for hastened death. Despite repeated recommendations for specialized care at a caregiver clinic, he declined. Following an argument with his wife at home, he felt unable to cope and attempted suicide. The husband had no psychiatric history but had a history of colon cancer. After the attempt suicide, he began visiting the “Caregivers’ Clinic,” where he received ongoing psychological support that continued until the death of his wife.
Significance of results
In cancer care, it is essential to continuously assess not only the patient’s suicide risk, but also that of closely related family members.
Over the past century, psychiatrists have neglected the importance of diet in the management of mental illness. This is especially the case in relation to mood disorders. There is now overwhelming evidence to support the view that a Mediterranean diet can play a role in the management of mood disorders. This is not in any way denying the importance of pharmacological and psychosocial strategies in the management of these disorders. Components of the Mediterranean diet not only impact brain function but also gut microbes, which are increasingly recognised as playing a role in the pathophysiology of mood disorders. Nutrition should be a component in the curriculum of psychiatrists in training.
To examine how race, income and food insecurity (FI) interact during pregnancy and whether FI contributes to disparities in maternal and infant health outcomes.
Design:
Observational cohort study employed sequential explanatory a mixed-methods design, with a survey phase (including Household Food Security Survey Module [HFSSM] six-item) and medical record abstraction followed by semi-structured interviews.
Setting:
Online survey, virtual interviews.
Participants:
The participants were individuals who gave birth in Louisiana, USA, between June 2020 and June 2021. The quantitative phase comprised 1691 individuals who completed the survey. A nested cohort of forty individuals (evenly split by race (Black v. White) and income (low v. high)) subsequently completed semi-structured interviews.
Results:
Race and income were independently associated with both FI and maternal and infant health outcomes. When considering both income and FI, low-income individuals with FI were 1·73 times more likely to deliver low birthweight (LBW) infants (adjusted Odds Ratio [aOR] 95 % CI: 1·07, 2·82) and 1·43 times more likely to experience adverse infant outcomes (aOR 95 % CI: 1·02, 2·00) than high-income individuals without FI. Black individuals with FI were 2·49 times more likely to deliver LBW infants (aOR 95 % CI: 1·45, 4·29) than White individuals without FI. Interview findings revealed low-income individuals faced disproportionate barriers to accessing healthy food and making dietary choices, which were further complicated by pregnancy-related conditions.
Conclusions:
The interplay between race, income and FI significantly increases the risk of adverse infant health outcomes, demonstrating a synergistic effect. Targeted efforts to address FI, particularly among low-income pregnant individuals, are essential to improving maternal and infant health outcomes.
In this prospective cohort study, trimethoprim-sulfamethoxazole direct oral challenge (DOC) for hospitalized adults reporting a low-risk sulfa antibiotic allergy was safe with 75/76 (99%) inpatients delabeled. Within 90-days of DOC, immunocompromised patients were more likely to receive trimethoprim-sulfamethoxazole, compared with non-immunocompromised patients (adjusted OR 5.6 95% CI 1.3, 23.0).
To estimate the prevalence of nutrition security and examine its association with community food environment factors, including food access and affordability.
Design:
This cross-sectional study used data from the 2012–2013 National Household Food Acquisition and Purchase Survey, including its restricted-use Geography Component (FoodAPS-GC). Household nutrition security measure was derived by combining self-assessed food security and self-rated diet quality indicators into four categories: food secure with high diet quality (FSHD), food secure with low diet quality (FSLD), food insecure with high diet quality (FIHD) and food insecure with low diet quality (FILD). Only FSHD households were considered nutrition secure. Multinomial logit analysis identified factors associated with nutrition security.
Participants:
4685 households with primary respondents aged 20 years or older
Setting:
Nationally representative sample of US households
Results:
Approximately 31·0 % of households were classified as nutrition insecure, including 15·0 % as FSLD, 9·3 % as FIHD and 6·7 % as FILD. The remaining 69·0 % were nutrition secure (FSHD). Nutrition insecurity was significantly associated with younger age, lower educational attainment, lower income, obesity, smoking and poorer self-rated health. Food environment factors, including low geographic access to food and higher local food prices, were not significantly associated with nutrition security. Relying on someone else’s car to reach a primary food store was linked to higher odds of nutrition insecurity.
Conclusions:
The proposed nutrition security measure can be used to monitor nutrition security in national surveys. Comprehensive measures of the food environment are needed to understand its relationship with nutrition security and to guide targeted policy interventions.
Educational attainment (EA), which comprises cognitive (CogEA) and noncognitive (NonCogEA) components, is positively genetically correlated with alcohol and cannabis use but negatively correlated with alcohol and cannabis use disorders (AUD and CUD). These paradoxical associations suggest that shared genetic influences with EA may differ by level of substance involvement.
Methods
To test this, we examined the shared genetic architecture of EA, CogEA, and NonCogEA with alcohol consumption (AC), AUD, lifetime cannabis use (CanUse), and CUD. We used bivariate causal mixture models, local genetic correlation analyses, and conditional/conjunctional false discovery rate analyses to identify global, regional, and variant-level overlap for EA and substance-related trait pairs.
Results
EA shared 57.57% of causal variants with AC and 62.42% with AUD, while sharing 48.07% of causal variants with CanUse and 84.18% with CUD. Among shared variants for AC, 48.12% had concordant effects with CogEA and 52.86% with NonCogEA. For AUD, 38.40% and 41.02% of causal variants had concordant effects with CogEA and NonCogEA, respectively. CanUse had higher concordance with CogEA (71.42%) and NonCogEA (65.56%) than CUD (37.97% and 42.23%, respectively). Functional enrichment in brain tissues varied across substance use and EA pairs.
Conclusions
EA is associated with greater alcohol and cannabis use and lower risk for AUD and CUD, a pattern that reflects both concordant and discordant variant effects. CogEA and NonCogEA show partially distinct patterns, particularly for cannabis-related traits, highlighting the importance of disaggregating EA to clarify the genetic architecture underlying its paradoxical associations with substance-related traits.
Powassan virus (POWV), a tick-borne flavivirus, is an emerging public health threat in the United States. In New York State (NYS), incidence of human POWV infection has increased in recent years. We describe the epidemiology of confirmed and probable POWV infection cases reported in NYS from 2013 to 2023. A total of 44 human cases were reported over the study period, with the highest incidence rates in Columbia and Putnam counties. Most cases occurred in White, non-Hispanic males over age 50. Hospitalization was reported in 91% of cases, and 11% were fatal. Human case data and tick surveillance results were analysed to assess spatiotemporal patterns of disease emergence. Spatial analysis revealed clustering of human cases in the Capital and Metropolitan regions of NYS. The prevalence of POWV in adult tick populations increased significantly statewide, and entomological risk was positively but modestly correlated to disease incidence at the ZIP code level. These findings suggest that POWV infection is emerging in geographically concentrated areas of NYS, highlighting the need for enhanced surveillance and targeted prevention efforts in high-risk regions.
Professional guidelines recommend an early switch from intravenous (IV)-to-oral antibiotics for community-acquired pneumonia (CAP) to facilitate early discharge and prevent hospital-related complications. However, it is unknown how often these IV-to-oral switches occur in clinical practice.
Design:
We performed a retrospective cohort study across 124 acute-care Veterans Administration hospitals to measure the frequency of early switches.
Patients:
Patient-admissions during 2018–2023 who had CAP and were started on IV antibiotics upon admission.
Methods:
We measured the percentage of hospitalized patients with CAP who had an early switch from IV-to-oral antibiotics, i.e., within 72 hours of admission. In addition, we calculated an observed-to-expected ratio for early switches at each hospital and compared a composite outcome (mortality and/or hospital readmission within 30 days of discharge) at hospitals with switch rates that were higher and lower than expected.
Results:
Of 31,183 patient-admissions for CAP, 17,282 (55.4%) were switched to oral antibiotics by day three of therapy. Overall, 5,629 (18.1%) died and/or were re-admitted within 30 days. The O:E ratio for early antibiotic switches ranged from 0.78 among hospitals in the lowest quartile to 1.23 in the highest quartile. There was no difference in the composite outcome across quartiles.
Conclusion:
Early switches from IV-to-oral antibiotics for CAP occurred in half of eligible cases. The frequency of these switches varied widely across facilities. Outcomes among patients at hospitals with high switch rates were comparable to outcomes at hospitals with low rates, thereby supporting the safety of early switches. More concerted efforts to promote these switches are needed.
The increasing diversity of the UK’s population, along with significant inequalities in health outcomes among diverse cultural and ethnic groups, highlights the critical need for healthcare providers, including physiotherapists, to deliver culturally competent care. Research demonstrates that cultural competency (CC) in healthcare can enhance patient outcomes, improve treatment adherence, and address health inequalities. This quality improvement project aimed to evaluate the impact of a brief training intervention on perceived CC among physiotherapists engaging in cross-cultural, clinical encounters.
Methods:
The design of this project was informed by principles of the Plan-Do-Study-Act (PDSA) cycle. Musculoskeletal physiotherapists voluntarily participated in this educational intervention by completing a CC e-learning course developed by Health Education England. A retrospective evaluation method was used, where participants rated their awareness, knowledge, and skills in providing care to diverse patient groups after completing the training as compared to before.
Results:
The pre-and post-training responses assessed three constructs of CC: awareness, knowledge, and skills. Significant increases were observed in the mean scores for each construct, as well as in the overall aggregate CC score, indicating measurable improvements following the training.
Conclusions:
Improvement in CC is viable and achievable through targeted training. CC is a lifelong, dynamic process that requires ongoing education. Therefore, further PDSA cycles are recommended with more advanced educational sessions. Additionally, future projects should assess the impact of enhanced CC on patient outcomes and experiences. Cultural competency must encompass cultural issues beyond racial and ethnic differences.
International studies show that school food programmes (SFP) can improve children’s diets but evidence from Canada is nascent. We examined whether SFP are linked to better dietary intake and diet quality among Canadian elementary schoolchildren. This cross-sectional study surveyed 2366 grade 4–8 students (age 9–14 years; 48·9 % girls) from 32 schools in socioeconomically disadvantaged communities in Alberta and Ontario, Canada. Students completed a 24-hour diet recall, recording foods and beverages consumed during school hours (breakfast, morning snack, lunch, afternoon snack), and their source (school, other). Multivariable linear models examined the association of accessing SFP (≥1 meal/snack provided by school) with student daily intakes of vegetables and fruit, grains and grain products, milk and alternatives, meat and alternatives, free sugars, sodium and diet quality, adjusting for relevant confounders. Only 293 (12·4 %) students accessed SFP. Overall, accessing SFP was associated with higher intake of vegetables and fruit (β = 0·4, 95 % CI = 0·1; 0·7) and better diet quality score (β = 1·8, 95 % CI = 0·7; 3·0). Specifically, morning snacks provided by schools were associated with lower intake of free sugars (β = –8·9, 95 % CI = –16·5; −1·4), while school-provided lunches were associated with higher intake of milk and alternatives (β = 0·5, 95 % CI = 0·2; 0·8). Further, school-provided afternoon snacks were associated with higher intake of vegetables and fruit (β = 1·1, 95 % CI = 0·6; 1·6), lower sodium intake (β = –258·4, 95 % CI = –506·7; −10·0) and better diet quality (β = 3·1, 95 % CI = 1·1; 5·1). One in eight elementary schoolchildren accessed SFP. Students who accessed SFP had better diets, highlighting the potential of SFP (particularly snacks) in improving children’s diets.
Understand current Candidozyma auris prevention practices in the United States and identify opportunities to improve containment.
Design:
Electronic survey.
Setting:
Acute care hospitals.
Participants:
Society for Healthcare Epidemiology (SHEA) Research Network (SRN) facilities located in the United States.
Methods:
REDCap survey distributed via email exploring knowledge and perceptions related to C. auris screening methods, prevention practices, barriers to prevention, and tools needed to improve containment.
Results:
Responses were received from 51/96 (53%) U.S.-based SRN facilities, with 80% identifying as teaching hospitals. Two-thirds of facilities (34/51) reported first-hand experience with C. auris, with 15/34 also experiencing at least one C. auris outbreak. Routine C. auris screening occurred in 47% (24/51) of facilities. C. auris prevention practices commonly included patient isolation, signage to notify staff of isolation status, and placement in a single patient room. When asked to identify barriers to control of C. auris at their facility, participants ranked lack of communication between healthcare facilities, lack of infection control at outside healthcare facilities, and lack of training as the top three barriers. C. auris prevention resources or tools perceived to be most helpful in their facility included effective decolonization regimens, standardized protocols for C. auris screening, and improved communication between healthcare facilities.
Conclusion:
SRN facilities commonly used isolation practices to prevent the spread of C. auris. Development of additional tools to improve prevention practices should target effective decolonization strategies and standardized screening protocols to support C. auris containment.
Persistent affective disturbance is a core, disabling feature of major depressive disorder (MDD), thought to stem from a dysfunctional interaction between emotional bias and cognitive control. However, the underlying neural dynamics are debated, with studies reporting both hyper- and hypoactivation. This study utilized high-temporal-resolution electroencephalogram (EEG) to resolve this discrepancy by examining distinct stages of emotional information processing.
Methods
We recruited 175 medication-free patients with MDD (Hamilton Depression Rating Scale-17 ≥ 14) and 101 healthy controls (HCs) who completed an emotional Stroop task while an EEG was recorded. We analyzed event-related potentials reflecting conflict monitoring (N250), inhibition (N450), and resolution (LSP) using a 2 (group) × 2 (valence) × 2 (congruency) analysis of variance.
Results
Results revealed a stage-specific neural cascade. Compared to HCs, the MDD group showed: (1) hypoactivation during initial conflict monitoring (attenuated N250 amplitude); (2) compensatory hyperactivation during conflict inhibition (a significant N450 interaction revealed generalized conflict activity in MDD, unlike the context-specific response in HCs); and (3) subsequent hypoactivation during conflict resolution (reduced LSP amplitude for negative stimuli). Crucially, altered N450 correlated with depression severity, and the entire neural cascade predicted behavioral performance.
Conclusions
The apparent contradiction in the literature reflects a multistage process. MDD is characterized by an inefficient neural cascade: an initial deficit in conflict monitoring is followed by compensatory overactivation during inhibition, which ultimately proves insufficient, leading to impaired late-stage resolution. This temporally specific model advances our understanding of the pathophysiology of depression and identifies potential stage-specific targets for intervention.
A self-binding directive (SBD) can be included in mental health advance decision documents to request future involuntary treatment. SBDs are supported by service users but controversial and empirical evidence on their application is scarce. Here we present a first case report which describes the experience of a service user with bipolar disorder (hereafter ‘bipolar’) who has chosen to use an SBD. We compare the findings of the case report with results from a systematic review of reasons for and against SBDs. We discuss that the experience of the service user supports SBDs as a tool to maximise autonomy and challenge criticisms around negative liberty, implementation, capacity assessment, and harms. We conclude that this case report adds to mounting evidence that SBDs are a feasible, ethically justifiable intervention, supported by service users. Policy makers should consider supporting SBD implementation strategies within crisis care.
Vitamin B6 is implicated in multiple mental disorders, and accumulating evidence suggests an inverse relationship with depression; however, important aspects of the underlying dose–response patterns and the roles of individual circulating vitamin B6 metabolites remain incompletely understood. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2005–2010. Depression was defined as a Patient Health Questionnaire-9 (PHQ-9) score ≥10. Vitamin B6 status was assessed using serum pyridoxal 5′-phosphate (PLP), the biologically active coenzyme form, and 4-pyridoxic acid (PA), the principal catabolic and urinary excretion product of vitamin B6. Among 12,620 participants, 1,070 (8.5%) met criteria for depression. After adjusting for relevant covariates, multiple logistic regression revealed that individuals in higher quartiles of serum PLP and PA (Q2-Q4) had significantly lower odds of depression compared to those in the lowest quartile (Q1). Restricted cubic spline analyses identified nonlinear relationships: L-shaped for PLP (P-nonlinearity=0.001) and U-shaped for PA (P-nonlinearity=0.017). Below the inflection points (90.7 nmol/L for PLP; 73.9 nmol/L for PA), both metabolites showed significant inverse associations with depression (PLP: OR=0.992, 95%CI: 0.988–0.996, P<0.001; PA: OR=0.994, 95%CI: 0.993–0.996, P<0.001). Above these thresholds, the association became non-significant for PLP (P=0.353), while PA demonstrated a positive association with depression (OR=1.008, 95%CI: 1.002–1.013, P<0.01). Subgroup analyses confirmed the robustness of these inverse associations across demographic categories. Serum vitamin B6 metabolites, PLP and its excretion product PA, exhibit non-linear associations with depression, with distinct threshold effects and metabolite-specific patterns that likely reflect both vitamin B6 availability and turnover.
Health Technology Assessment (HTA) guides healthcare decision-making, while Implementation Research (IR) addresses challenges in operationalizing these decisions. The SAVING (Sustainable Access and Delivery of New Vaccines in Ghana) Consortium aims to enhance health intervention delivery in Ghana, focusing on HTA evidence. This study identifies barriers to the application of HTA-related evidence (cost analysis) in coronavirus disease 2019 (COVID-19) vaccine deployment in Ghana.
Methods
This qualitative exploratory study purposively selected 12 key stakeholders with high interest and power relating to COVID-19 vaccine deployment in Ghana. Through in-depth interviews, seven stakeholders from diverse sectors contributed insights into barriers to the application of HTA-related evidence. Thematic analysis was conducted with narrative reporting supported by direct quotes for substantiation.
Results
Six main barriers were identified: (1) timing and access to HTA reports, (2) technical complexities, (3) relevance of content, (4) political considerations and power dynamics, (5) health system fragmentation, and (6) poor responsiveness of decision-makers to research. Proposed solutions include engaging political decision-makers continuously, simplifying technical reports, aligning report content with policymakers’ needs, reducing political considerations, enhancing capacity building, fostering health system cohesion, and improving responsiveness to research.
Conclusions
HTA is vital for informed healthcare decisions. However, technical complexity, relevance of content, inappropriate timing, and lack of access to HTA reports, among other barriers, prevent the uptake of HTA findings. Continuous and improved engagement between HTA producers and policymakers, along with rapid production of HTA, has the potential to improve the uptake of HTA findings, even during public health emergencies.
