RESUMO
The early detection of lung cancer (LC) improves patient outcomes, but current methods have limitations. Autoantibodies against tumor-associated antigens have potential as early biomarkers. This study evaluated the 9G testTM Cancer/Lung, measuring circulating complexes of two antigen-autoantibody immune complexes (AIC) against their respective free antigens (CYFRA 21-1 and p53) for LC diagnosis. We analyzed 100 LC patients and 119 healthy controls using the 9G testTM Cancer/Lung, quantifying the levels of AICs (CYFRA 21-1-Anti-CYFRA 21-1 autoantibody immune complex (CIC) and p53-Anti-p53 autoantibody immune complex (PIC)), free antigens (CYFRA 21-1 and p53), and ratios of AICs/antigens (LC index). The levels of the CICs and PICs were significantly elevated in LC compared to the controls (p < 0.0062 and p < 0.0026), while free antigens showed no significant difference. The CIC/CYFRA 21-1 and PIC/p53 ratios were also significantly higher in LC (all, p < 0.0001). The LC index, when combining both ratios, exhibited the best diagnostic performance with an area under the curve (AUC) of 0.945, exceeding individual CICs, PICs, and free antigens (AUCs ≤ 0.887). At a cut-off of 3.60, the LC index achieved 81% sensitivity and 95% specificity for LC diagnosis. It detected early-stage (Stage I-II) LC with 87.5% sensitivity, exceeding its performance in advanced stages (72.7%). The LC index showed no significant differences based on age, gender, smoking status (former, current, or never smoker), or pack years smoked. The LC index demonstrates promising potential for early LC diagnosis, exceeding conventional free antigen markers.
RESUMO
We examined associations between prenatal tobacco exposure (with and without cannabis exposure) and children's performance on laboratory measures of sustained attention, attentional set shifting, and working memory in middle childhood (9-12 years of child age). Participants were recruited in the first trimester of pregnancy and oversampled for prenatal tobacco exposure; with a smaller sample (n = 133; n = 34 non-substance exposed, n = 37 exposed to tobacco only, n = 62 co-exposed) invited (oversampled for co-exposure) to participate in the middle-childhood assessment (M age = 10.6, SD = 0.77; 68% Black, 20% Hispanic). Results for sustained attention indicated lower attention (percent hits) at the first epoch for tobacco only exposed compared to non-exposed and co-exposed; a trend (p = .07) towards increases in impulsive responding across time (a total of 8 epochs) for tobacco exposed (with and without cannabis) compared to non-exposed children; and a significant association between higher number of cigarettes in the first trimester and greater increases in impulsive responding across epochs. However, children prenatally exposed to tobacco (with and without cannabis) demonstrated greater short-term memory compared to children not prenatally exposed, and this difference was driven by higher scores for children prenatally co-exposed to tobacco and cannabis compared to those who were non-exposed. Overall, results suggest that prenatal tobacco exposure, especially in the first trimester, may increase risk for impulsive responding on tasks requiring sustained attention, and that co-use of cannabis did not exacerbate these associations. The higher short-term memory scores among children who were co-exposed compared to non-exposed are perplexing and need replication, particularly in studies with larger sample sizes and samples exposed only to cannabis to examine this more closely.

BACKGROUND: Suicide rates in older adults are much higher than those in younger age groups. Given the rapid increase in the proportion of older adults in Korea and the high suicide rate of this age group, it is worth investigating the mechanism of suicidal ideation for older adults. Generally, adverse childhood experiences are positively associated with suicidal ideation; however, it is not fully understood what mediating relationships are linked to the association between these experiences and current suicidal ideation. METHODS: The data from 685 older Korean adults were analyzed utilizing logistic regression, path analyses, and structural equation modeling. Based on our theoretical background and the empirical findings of previous research, we examined three separate models with mental health, physical health, and social relationship mediators. After that, we tested a combined model including all mediators. We also tested another combined model with mediation via mental health moderated by physical health and social relationships. RESULTS: The univariate logistic regression results indicated that childhood adversity was positively associated with suicidal ideation in older adults. However, multivariate logistic regression results demonstrated that the direct effect of childhood adversity became nonsignificant after accounting all variables. Three path models presented significant mediation by depression and social support in the association between childhood adversity and suicidal ideation. However, combined structural equation models demonstrated that only mediation by a latent variable of mental health problems was statistically significant. Social relationships moderated the path from mental health problems to suicidal ideation. CONCLUSIONS: Despite several limitations, this study has clinical implications for the development of effective strategies to mitigate suicidal ideation. In particular, effectively screening the exposure to adverse childhood experiences, early identification and treatment of depressive symptoms can play a crucial role in weakening the association between childhood adversity and suicidal ideation in older adults.

Rising cancer survival rates have led to an increased risk of multiple primary cancers (MPCs). Data on MPCs in South Korea are limited. This study aimed to address incidence and clinical characteristics of MPCs in a single cancer center in Korea during a 20-year period. We retrospectively analyzed 96,174 cancer patients at the Korea Cancer Center Hospital between 2003 and 2022, identifying 2167 patients with metachronous MPCs based on Surveillance, Epidemiology, and End Results SEER criteria. We categorized patients by cancer type (15 major solid cancer groups and 3 major hematologic cancer groups), including pathological diagnosis, assessed latency periods, and relative risks (RRs) for developing MPCs. The overall MPC incidence was 2.3%. Breast cancer (15.7%) was the most common primary cancer, and lung cancer (15.2%) was the most frequent second primary cancer. The median latency period for second primary cancers was 4.1 years. Decreasing latency periods for third and fourth primary cancers were observed (2.1 years and 1.6 years, respectively). Most cancers maintained their dominant pathological type despite notable changes in the prevalence of specific pathologies for certain types of second primaries. Lymphoma showed the highest RR (2.1) for developing MPCs. Significant associations were found between specific primary and subsequent cancers, including breast-ovary, thyroid-breast, stomach-pancreas, colorectal-head and neck, lung-prostate, and lymphoma-myeloid neoplasms. These findings contribute to a better understanding of MPC occurrence. They can inform future research on their etiology and development of improved management strategies.
RESUMO
INTRODUCTION: Despite the high prevalence of major depressive disorder (MDD) among the elderly population, the rate of treatment is low due to stigmas and barriers to medical access. Wearable devices such as smartphones and smartwatches can help to screen MDD symptoms earlier in a natural setting while forgoing these concerns. However, previous research using wearable devices has mostly targeted the younger population. By collecting longitudinal data using wearable devices from the elderly population, this research aims to produce prediction algorithms for late-life depression and to develop strategies that strengthen medical access in community care systems. METHODS AND ANALYSIS: The current cohort study recruited a subsample of 685 elderly people from the Korean Genome and Epidemiology Study-Cardiovascular Disease Association Study, a national large cohort established in 2004. The current study has been conducted over a 3-year period to explore the development patterns of late-life depression. Participants have completed three annual face-to-face interviews (baseline, the first follow-up and the second follow-up) and 2 years of app-based surveys and passive sensing data collection. All the data collection will end at the second follow-up interview. The collected self-report, observational and passive sensing data will be primarily analysed by machine learning. ETHICS AND DISSEMINATION: This study protocol has been reviewed and approved by the Yonsei University Mirae Campus Institutional Review Board (1041849-2 02 111 SB-180-06) in South Korea. All participants provided written informed consent. The findings of this research will be disseminated by academic publications and conference presentations.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can be diagnosed using rapid real-time polymerase chain reaction (PCR), real-time reverse transcription PCR (rRT-PCR), or rapid antigen testing. Among these, rRT-PCR is considered the gold standard assay. The Xpert Xpress SARS-CoV-2 assay is a rapid, real-time PCR test; approved by the Korean Disease Control and Prevention Agency in 2020. Current performance of the Xpert assay (Xpert) with the STANDARD M nCoV Real-Time Detection kit (SD) were determined. METHODS: All samples used by the SD test team were immediately transferred to the Xpert test team within 24 hours. Both tests were conducted between April 2023 and July 2023. Exclusion criteria were studies which show either inconclusive, invalid, or erroneous results. Positive rate, sensitivity, specificity, overall concordance rate, positive concordance rate, discordance rate, false-positive rate, and false-negative rates of the Xpert assay with the STANDARD M nCoV Real-Time Detection kit were determined. RESULTS: Samples from 347 patients (174 men and 173 women) with a median age of 60 years (range; 6 - 90 years) were included. Positive rate, sensitivity, specificity, overall concordance rate, positive concordance rate, discordance rate, false-positive rate, and false-negative rates of the Xpert assay were 11.2%, 82.1%, 95.0%, 93.9%, 6.6%, 6.1%, 41.0%, and 1.6%, respectively. CONCLUSIONS: COVID-19 results from Xpert should be confirmed through rRT-PCR because of low sensitivity (82.1%) and high false-positive rate (41.0%).

Budget analysis entities often cannot capture the full downstream impacts of investments in prevention services, programs, and interventions. This study describes and applies an approach to synthesizing existing literature to more fully account for these effects. This study reviewed meta-analyses in PubMed published between Jan 1, 2010 and Dec 31, 2019. The initial search included meta-analyses on the association between health risk factors, including maternal behavioral health, intimate partner violence, child maltreatment, depression, and obesity, with a later health condition. Through a snowball sampling-type approach, the endpoints of the meta-analyses identified became search terms for a subsequent search, until each health risk was connected to one of the ten costliest health conditions. These results were synthesized to create a path model connecting the health risks to the high-cost health conditions in a cascade. Thirty-seven meta-analyses were included. They connected early-life health risk factors with six high-cost health conditions: hypertension, diabetes, asthma and chronic obstructive pulmonary disorder, mental disorders, heart conditions, and trauma-related disorders. If confounders could be controlled for and causality inferred, the cascading associations could be used to more fully account for downstream impacts of preventive interventions. This would support budget analysis entities to better include potential savings from investments in chronic disease prevention and promote greater implementation at scale.

BACKGROUND: COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can be diagnosed using rapid real-time PCR, real-time reverse transcription PCR (rRT-PCR), or rapid antigen testing. Among these, rRT-PCR is considered the gold standard assay. The Xpert Xpress SARS-CoV-2 assay is a rapid real-time PCR test, approved by the Korean Disease Control and Prevention Agency in 2020. The overall concordance and positive concordance rates of the Xpert assay with the STANDARD M nCoV Real-Time Detection kit were determined. METHODS: All samples with positive or inconclusive Xpert test results from July 2021 to February 2023 that underwent confirmatory testing using the reference rRT-PCR assay were included in the analysis. RESULTS: Samples from 224 patients (93 men and 131 women) with a median age of 59 years (range 15 - 90 years) were included. Of 212 samples that tested positive using Xpert, 112 (52.8%) were true positves and 100 (47.2%) were false positives on rRT-PCR testing. The overall concordance and positive concordance rates were 52.8% (112/212) and 54.5% (112/224), respectively. In the Xpert positive group, the samples had a lower Ct value for the E gene than the N2 gene. The Ct values for the E and N2 genes were significantly lower in the positive group than in the inconclusive group. CONCLUSIONS: Positive or inconclusive Xpert results should be confirmed by the gold standard rRT-PCR for early control of this disease. Furthermore, Korea's policy should be reconsidered given the high false-positive rate of the rapid real-time PCR Xpert Xpress SARS-CoV-2 assay.

Autoantibodies against specific lung cancer-associated antigens have been suggested for the performance of lung cancer diagnosis. This study aimed to evaluate the diagnostic performance of the antigen-autoantibody immune complex (AIC) against its free antigens for CYFRA21-1, ProGRP, neutrophil gelatinase-associated lipocalin (NGAL), and neuron-specific enolase (NSE) in non-small cell lung cancer (NSCLC). In total, 85 patients with NSCLC and 120 healthy controls (HCs) were examined using a 9-guanine DNA chip method. The ratios of AICs to their antigens and the combinations of ratios consisting of two to four markers were calculated. The levels of AICs for CYFRA21-1, ProGRP, NGAL, and NSE were higher than those for their free antigens in all participants. The levels of each free antigens distinguished patients with NSCLC from the HCs. The ratios of the AIC to its antigen and seven combinations of two to four ratios were significantly higher in patients with NSCLC than in the HCs. Excellent diagnostic performance was observed for all combination ratios (C4-1), with 85.9% sensitivity and 86.7% specificity at a 3.51 cut-off. Higher sensitivity was observed in the early stages (0-I) and adenocarcinoma than in stages II-IV and other pathological types. Combining all ratios of AICs and their antigens for all four markers was useful when diagnosing NSCLC.
RESUMO
Background: As life expectancy increases, understanding the mechanism for late-life depression and finding a crucial moderator becomes more important for mental health in older adults. Childhood adversity increases the risk of clinical depression even in old age. Based on the stress sensitivity theory and stress-buffering effects, stress would be a significant mediator, while social support can be a key moderator in the mediation pathways. However, few studies have tested this moderated mediation model with a sample of older adults. This study aims to reveal the association between childhood adversity and late-life depression in older adults, taking into consideration the effects of stress and social support. Methods: This study used several path models to analyze the data from 622 elderly participants who were never diagnosed with clinical depression. Results: We found that childhood adversity increases the odds ratio of depression by approximately 20% in older adults. Path model with mediation demonstrates that stress fully mediates the pathway from childhood adversity to late-life depression. Path model with moderated mediation also illustrates that social support significantly weakens the association between childhood adversity and perceived stress. Conclusion: This study provides empirical evidence to reveal a more detailed mechanism for late-life depression. Specifically, this study identifies one crucial risk factor and one protective factor, stress and social support, respectively. This brings insight into prevention of late-life depression among those who have experienced childhood adversity.
RESUMO
Background: In non-small cell lung cancer (NSCLC), epidermal growth factor receptor (EGFR) mutation testing of tumor tissue should be conducted at diagnosis. Alternatively, circulating tumor DNA can be used to detect EGFR mutation. We compared the cost and clinical effect of three strategies according to the application of the EGFR test. Methods: Decision models were developed to compare the cost-effectiveness of tissue-only, tissue-first, and plasma-first diagnostic strategies as first- and second-line treatments for NSCLC from the perspective of the Korean national healthcare payer. Progression-free survival (PFS), overall survival (OS), and direct medical costs were assessed. A one-way sensitivity analysis was performed. Results: The plasma-first strategy correctly identified numerous patients in the first- and second-line treatments. This strategy also decreased the cost of biopsy procedures and complications. Compared with that when using the other two strategies, the plasma-first strategy increased PFS by 0.5 months. The plasma-first strategy increased OS by 0.9 and 1 month compared with that when using the tissue-only and tissue-first strategies, respectively. The plasma-first strategy was the least expensive first-line treatment but the most expensive second-line treatment. First-generation tyrosine kinase inhibitor and the detection rate of the T790M mutation in tissues were the most cost-influential factors. Conclusions: The plasma-first strategy improved PFS and OS, allowing for a more accurate identification of candidates for targeted therapy for NSCLC and decreased biopsy- and complication-related costs.

BACKGROUND: Although the association between prenatal tobacco exposure and child obesity risk is well-established, less is known about co-exposure to tobacco and cannabis. OBJECTIVE: Determine the relation between prenatal substance co-exposure and obesity risk. METHODS: In a diverse sample of pregnant women, we examined the association between prenatal substance exposure (tobacco-only and co-exposure) and child BMI (kg/m2 ) trajectories from birth to mid-childhood (n = 262), overweight/obese status based on BMI percentiles from toddlerhood (24 months) to mid-childhood (9-12 years), and adiposity outcomes at mid-childhood (fat mass [kg], fat mass [%] and fat free mass [kg]; n = 128). Given that the major goal of this study was to examine the associations between prenatal substance exposure and child outcomes, we oversampled pregnant women for substance use (with tobacco as the primary focus). RESULTS: Multilevel models demonstrated that children in both exposure groups had a steeper increase in BMI trajectory from birth to mid-childhood and among co-exposed children, girls had a steeper increase than boys. Odds ratio of having obesity by mid-childhood was 12 times higher among those co-exposed than non-exposed. Co-exposure led to significantly greater fat mass and fat mass % compared with no exposure, but exposure to only tobacco was no different than no exposure. CONCLUSIONS: Results highlight potentiating effects of cannabis exposure in the context of maternal tobacco use in pregnancy on obesity risk and the importance of multi-method assessments of obesity.

Fathers' positive engagement (FPE) benefits children's development but some children receive greater FPE than others. Understanding why some fathers demonstrate greater FPE than others is critical to efforts to support FPE. However, studies of FPE often fail to account for the father's residential context and changes in interparental relationships and FPE that occur as the child develops. This study examined the effects of paternal identity (i.e., status-level/role-level centrality) and maternal gate opening on FPE in diverse residential contexts from early to middle childhood. Using longitudinal multilevel modeling, this study analyzed data from 2,339 families in the Fragile Families and Child Wellbeing Study. Results demonstrated that maternal gate opening strengthened the association between paternal status-level centrality and FPE, especially, for fathers who were nonresident at childbirth. This protective effect did not change by child age. Furthermore, fathers who were resident at childbirth but nonresident in middle childhood increased in FPE over time. However, among fathers whose residential status shifted from nonresident to resident, those with low role-level centrality decreased in FPE over time. For fathers who were resident from birth to middle childhood, high maternal gate opening was associated with greater FPE, although this effect faded over time. Overall, these findings suggest the importance of both establishment of a strong paternal identity and maintenance of maternal support to promote long-term FPE.

OBJECTIVE: The postpartum period is a key life stage, contributing to increased maternal obesity risk. Current lifestyle interventions do not consider the role of a woman's partner in reducing stress and supporting lifestyle change. The objective of this study was to assess the effect of an intervention that seeks to enhance coparenting relationship quality on maternal BMI from before conception to 12 months post partum and whether the intervention moderated the association of changes in cortisol and BMI. METHODS: A randomized controlled trial was used to assess an intervention (eight classes: four during and four following pregnancy) focusing on enhancing couple coparenting relationships during pregnancy and post partum (n = 57) compared with standard care (n = 53). RESULTS: The main outcome measures were changes in maternal BMI and cortisol. There was a smaller increase in BMI for mothers in intervention compared with control groups (mean [SE], -1.03 [0.42] kg/m2 , p = 0.015). There was an interaction between intervention status and cortisol change predicting BMI change (p = 0.026), such that cortisol change significantly predicted BMI change among mothers in the control (p = 0.049) but not the intervention groups (p = 0.204). CONCLUSIONS: A coparenting intervention improved maternal postpartum BMI, with this effect potentially related to ameliorating the negative effect of stress, as measured by cortisol, on BMI. The role of enhanced coparenting in improving maternal anthropometry warrants urgent attention.

With the rapid spread of the coronavirus disease (COVID-19), the need for rapid testing and diagnosis and consequently, the demand for mobile laboratories have increased. Despite this need, there are no clear guidelines for the operation, maintenance, or quality control of mobile laboratories. We provide guidelines for the operation, management, and quality control of mobile laboratories, and specifically for the implementation and execution of COVID-19 molecular diagnostic testing. These practical guidelines are primarily based on expert opinions and a laboratory accreditation inspection checklist. The scope of these guidelines includes the facility, preoperative evaluation, PCR testing, internal and external quality control, sample handling, reporting, laboratory personnel, biosafety level, and laboratory safety management. These guidelines are useful for the maintenance and operation of mobile laboratories not only in normal circumstances but also during public health crises and emergencies.

As the COVID-19 pandemic has been highly stressful for parents and children, it is clear that strategies that promote long-term family resilience are needed to protect families in future crises. One such strategy, the Family Foundations program, is focused on promoting supportive coparenting at the transition to parenthood. In a randomized trial, we tested the long-term intervention effects of Family Foundations on parent, child, and family well-being one to two months after the imposition of a national shelter-in-place public health intervention in 2020. We used regression models to test intervention impact on outcomes reported on by parents in a standard questionnaire format and a series of 8 days of daily reports. We also tested moderation of intervention impact by parent depression and coparenting relationship quality. Relative to control families, intervention families demonstrated significantly lower levels of individual and family problems (general parent hostility, harsh and aggressive parenting, coparenting conflict, sibling relationship conflict, and children's negative mood and behavior problems), and higher levels of positive family relationship quality (positive parenting, couple relationship quality, sibling relations, and family cohesion). For some outcomes, including coparenting conflict, harsh parenting, and child behavior problems, intervention effects were larger for more vulnerable families-that is, families with higher pre-pandemic levels of parent depression or lower levels of coparenting relationship quality. We conclude that targeted family prevention programming is able to promote healthy parent and child functioning during unforeseen future periods of acute stress. The long-term benefits of a universal approach to family support at the transition to parenthood indicate the need for greater investment in the dissemination of effective approaches.
Dado que la pandemia de COVID-19 ha sido muy estresante para padres e hijos, está claro que se necesitan estrategias que promuevan la resiliencia familiar a largo plazo para proteger a las familias en crisis futuras. Una de esas estrategias, el programa Family Foundations, se centra en promover la crianza compartida de apoyo en la transición a la paternidad. En un ensayo aleatorizado, probamos los efectos de la intervención a largo plazo de Family Foundations en el bienestar de los padres, el niño y la familia uno o dos meses después de la imposición de una intervención nacional de salud pública de refugio en el lugar en 2020. Usamos modelos de regresión para evaluar el impacto de la intervención en los resultados informados por los padres en un formato de cuestionario estándar y una serie de 8 días de informes diarios. También probamos la moderación del impacto de la intervención por la depresión de los padres y la calidad de la relación de coparentalidad. En relación con las familias de control, las familias de intervención demostraron niveles significativamente más bajos de problemas individuales y familiares (hostilidad general de los padres, crianza dura y agresiva, conflicto de crianza conjunta, conflicto de relaciones entre hermanos y problemas de comportamiento y estado de ánimo negativos de los niños) y niveles más altos de calidad de relación familiar positiva (crianza positiva, calidad de la relación de pareja, relaciones entre hermanos y cohesión familiar). Para algunos resultados, incluido el conflicto de crianza compartida, la crianza severa y los problemas de comportamiento infantil, los efectos de la intervención fueron mayores para las familias más vulnerables, es decir, familias con niveles más altos de depresión de los padres prepandémicos o niveles más bajos de calidad de la relación de crianza compartida. Concluimos que los programas de prevención familiar específicos pueden promover el funcionamiento saludable de padres e hijos durante períodos futuros imprevistos de estrés agudo. Los beneficios a largo plazo de un enfoque universal del apoyo familiar en la transición a la paternidad indican la necesidad de una mayor inversión en la difusión de enfoques eficaces.

Early childhood is critical to the development of children's social-emotional competence, which predicts peer relations and school adjustment in later periods of childhood. The effects of experiencing or witnessing aggression on children's social-emotional development are well known, yet the role of conflict resolution within the family has not been sufficiently studied. Social information processing models suggests that children who experience positive forms of conflict resolution within the family are likely to generalize these experiences and related skills outside the family, and thus develop greater social-emotional competence. In this longitudinal study, 128 parents (representing 79 families) participated in four quarterly telephone interviews in which they described aggressive conflicts that occurred in their family for which their children were present, including the degree to which each conflict was resolved. They also reported on the frequency of intimate partner aggression (IPA) and parent-to-child aggression (PCA) that occurred while the child was in toddlerhood and preschool as well as children's social-emotional competence at the end of the study. Multi-level models reveal that parents' reports of positive conflict resolution mitigated the concurrent and longitudinal negative effects of children's exposure to both IPA and PCA on their social-emotional competence. These findings reinforce prevention scientists' emphasis on conflict resolution skills as an essential component of parent education programs.
La primera infancia es fundamental para el desarrollo de la competencia socioemocional de los niños, la cual predice las relaciones entre pares y la adaptación escolar en periodos posteriores de la niñez. Se conocen muy bien los efectos que producen el sufrir o ser testigos de agresión en el desarrollo socioemocional de los niños, sin embargo, aún no se ha estudiado de manera suficiente el papel que desempeña la resolución de conflictos dentro de la familia. Los modelos de procesamiento de la información social sugieren que los niños que viven formas positivas de resolución de conflictos dentro de la familia son propensos a generalizar estas experiencias y las habilidades afines fuera de la familia y, por lo tanto, a desarrollar una mayor competencia socioemocional. En este estudio longitudinal, 128 padres (que representaban 79 familias) participaron en cuatro entrevistas telefónicas cada tres meses en las cuales describieron conflictos agresivos que hubo en su familia en los cuales sus hijos estuvieron presentes, incluido el grado en el cual se resolvió cada conflicto. También informaron la frecuencia de agresión en la pareja y de agresión de padres a hijos que tuvo lugar durante sus primeros años de vida y en la etapa del preescolar, así como la competencia socioemocional de los niños al final del estudio. Los modelos multinivel indican que los informes de los padres sobre la resolución positiva de los conflictos mitigaron los efectos negativos longitudinales y simultáneos de la exposición de los niños a la agresión en la pareja y a la agresión de padres a hijos en su competencia socioemocional. Estos resultados refuerzan el énfasis en las habilidades de resolución de conflictos de los científicos de la prevención como componente esencial de los programas de educación para padres.

To quantify the impact of the COVID-19 pandemic and public health interventions on parent and child mental health and family relationships, we examined change in individual and family functioning in a sample of parents enrolled in a prevention trial; we examined change before the pandemic (2017-2019) when children were an average of 7 years old to the first months after the imposition of widespread public health interventions in the United States (2020) with paired t tests and HLM models. We examined moderation by parent gender, education, family income, and coparenting conflict. We found large deteriorations from before the pandemic to the first months of the pandemic in child internalizing and externalizing problems and parent depression, and a moderate decline in coparenting quality. Smaller changes were found for parent anxiety and parenting quality. Mothers and families with lower levels of income were at particular risk for deterioration in well-being. Results indicate a need for widespread family support and intervention to prevent potential family "scarring," that is, prolonged, intertwined individual mental health and family relationship problems.
Para cuantificar el efecto de la pandemia de la COVID-19 y de las intervenciones de salud pública en la salud mental de los padres y los niños y en las relaciones familiares, analizamos los cambios en el funcionamiento individual y familiar en una muestra de padres inscriptos en un ensayo de prevención; estudiamos el cambio antes de la pandemia (2017-2019) cuando los niños tenían un promedio de 7 años hasta los primeros meses después de la imposición de las intervenciones generalizadas de salud pública en los Estados Unidos (2020) con pruebas t apareadas y modelos lineales jerárquicos. Analizamos la moderación por género, educación, ingresos familiares y conflicto de cocrianza de los padres. Hallamos grandes deterioros desde antes de la pandemia hasta los primeros meses de la pandemia en problemas de interiorización y exteriorización de los niños y depresión de los padres, y una disminución moderada de la calidad de la cocrianza. También encontramos cambios más pequeños en la ansiedad de los padres y la calidad de la crianza. Las madres y las familias con niveles más bajos de ingresos estuvieron en riesgo particular de deterioro del bienestar. Los resultados indican la necesidad de apoyo familiar generalizado y de intervenciones para prevenir posibles «secuelas¼ familiares, p. ej.: salud mental individual interconectada y prolongada y problemas en las relaciones familiares.

BACKGROUND: Analytical performance should be evaluated before a new coagulation analyzer is adopted in a clinical laboratory. The objective of this study was to evaluate analytical performances of three new coagulation analyzers (STA-R Max3, CN-6000, and Cobas t511) and compare them based on the following four coagulation parameters: prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, and D-dimer. METHODS: A total of 427 plasma samples, including fresh and frozen/thawed plasma spanning wide ranges. Each of the manufacturers' quality control samples were used for the evaluation. Analytical performances were evaluated. Parameters considered were precision, carryover, verification of analytical measurement range, auto-dilution, and reference range according to the CLSI guidelines (H57-A). The results of each parameter were compared between STA-R compact (currently in use) and three new analyzers using fresh plasma. The results were compared among three new analyzers using fresh and frozen/thawed plasma, and samples with interferences of hemolysis/icterus/ lipemia (H/I/L). RESULTS: Analytical performances were excellent for all analyzers within each manufacturer's target based on results of precision, carryover, linearity, and verifications of auto-dilution, and reference range. Results for four parameters (PT/aPTT/fibrinogen/D-dimer) with the three new analyzers using fresh samples were well-correlated with those of STA-R Compact except for D-dimer tests (Pearson's r: 0.84 to 1.00). Good correlations were observed between the new analyzers with the total samples (fresh and frozen/thawed samples) (Pearson's r, 0.86 to 0.97). However, weaker correlation and/or higher mean bias% were observed for aPTT and D-dimer with total samples and for four parameters with normal samples rather than abnormal samples across the three analyzers. Differences were more prominent with H/I/L samples, especially between STA-R Max3 and CN-6000 or Cobas t511 for PT, aPTT, and D-dimers. CONCLUSIONS: With excellent analytical performances, the three new coagulation analyzers demonstrated good correlations, although high variabilities were seen for aPTT and D-dimers. High variability in comparison analysis might be mainly attributed to differences in reference and reportable ranges of each parameter across the three different analyzers.

This study examined predictors of new fathers' parenting satisfaction and stress using data from 182 fathers in dual-earner couples who were followed across their transition to parenthood. Expectant fathers completed surveys about their personal characteristics (anxiety, belief in maternal essentialism, parenting self-efficacy expectations) and family relationships (confidence in the couple relationship) during the third trimester of pregnancy. At three months postpartum, fathers completed surveys about their family relationships (maternal gatekeeping) and child characteristics (infant negative emotionality, infant gender), as well as their parenting satisfaction and stress. Results of regression analyses indicated that expectant fathers with greater parenting self-efficacy expectations reported less parenting stress and greater satisfaction at three months postpartum. More anxious expectant fathers were at risk of experiencing elevated levels of parenting stress postpartum, as were fathers with lower endorsement of maternal essentialism and infants highly negative in mood. Fathers were more satisfied in their roles as parents when mothers engaged in greater gate-opening behavior, particularly when those fathers expressed less confidence in their couple relationships prior to their child's birth. Results indicate the importance of screening expectant and new fathers for anxiety, strengthening expectant fathers' parenting self-efficacy, and encouraging greater maternal support for engaged fathering.
