Associations of Homelessness With Primary Care and Acute Care Utilization Among Medicaid-Enrolled Youth.

BACKGROUND: Youth comprise one-third of the US homeless population. However, little is known about how homelessness affects health care utilization. OBJECTIVE: Examine associations of homelessness with hospitalization, primary care, and ED visits, varying by race/ethnicity, among Medicaid-enrolled youth. RESEARCH DESIGN: A cross-sectional analysis was conducted using California Medicaid claims data on youth beneficiaries with complex needs. We examined the number of hospitalizations, preventable and nonpreventable ED, and primary care visits using a multivariate regression. We further explored the differential associations by race/ethnicity. RESULTS: Approximately 17% of our sampled youth experienced homelessness in 2018 (N=90,202). Compared with their housed counterparts, youth experiencing homelessness had a 1.9 percentage point (pp) higher likelihood of frequent ED visits (95% CI: 1.7-2.2) but a 2.9 pp lower probability of any primary care visits (95% CI: -3.9 to -1.9). Homelessness was associated with 221 more ED visits (95% CI: 182-260), 100 more preventable ED visits (95% CI: 84-116), 19.9 more hospitalizations (95% CI: 12-27), but 56 fewer primary care visits (95% CI: -104 to -7), per 1000 youth. The associations of homelessness with total ED visits, preventable ED visits, and needed and nonpreventable ED visits were all higher among Whites and, particularly, Blacks than for Hispanics and Asians. CONCLUSIONS: Medicaid-enrolled youth who experienced homelessness had more overall ED, preventable ED, and hospital visits, but fewer primary care visits than their housed peers. Our results suggest promoting primary care use should be considered among strategies to improve health and reduce costs.

Real-world evidence of lupus anticoagulant testing: simultaneous positivity of diluted Russell's viper venom time and silica clotting time increases thrombotic risk prediction.

Lupus anticoagulant (LA) is composed of heterogeneous autoantibodies, which have a close association with thrombotic events. Due to its heterogeneity, two methods for increasing sensitivity are recommended for LA. An investigation of the thrombotic risk and anticardiolipin (aCL) and anti-ß2-glycoprotein I (aB2GPI) antibody profiles was conducted based on the results of using two parallel methods (dilute Russell viper venom time (dRVVT), silica clotting time (SCT)) in a real world clinical laboratory. Of 5120 patients, 684 patients (13%) were LA positive, and 422 patients (8%) experienced thrombotic events including pregnancy complication. Development of thrombotic events was more likely to occur in patients who were positive for both dRVVT and SCT compared with those who were positive for dRVVT or SCT only. In addition, significantly higher positive rates of aCL and aB2GPI and the persistently positive rate of LA at intervals of 12 weeks or longer were observed in patients who were positive for both dRVVT and SCT compared with those who were positive for dRVVT or SCT only. Considering three laboratory tests (LA, aCL, and aB2GPI), high thrombotic risk was observed for patients with both dRVVT and SCT positive LA results. A report on LA results that divides LA positive into two types (LA-single positive and LA-both positive) may be beneficial to clinicians in detection of high-risk thrombotic patients.

The development of digital ownership in children.

The current study examined whether, for children and adults, behaviors that are considered violations of property rights in the case of physical property are likewise viewed as violations in the case of digital property. In this preregistered study (N = 156), 5- to 10-year-old children and adults heard a story about a person who downloaded a digital file (e.g., an e-book that she did not own) onto her personal computer (digital) versus a person who put a physical item (e.g., a book that she did not own) into her bag (physical). Participants were asked to evaluate how okay each behavior is. We found that from 5 years of age children evaluated taking a physical object more negatively than downloading a digital file, which was also the pattern observed in adults. Furthermore, by 9 years of age children were equivalent to adults in their evaluation of downloading digital files. The current study has implications for the development of ownership in children.

Children's judgments of interventions against norm violations: COVID-19 as a naturalistic case study.

The coronavirus pandemic has had a significant influence on social interactions, introducing novel social norms such as mask-wearing and social distancing to protect people's health. Because these norms and associated practices are completely novel, it is unknown how children assess what kinds of interventions are appropriate under what circumstances and what principles they draw on in their decisions. We investigated children's reasoning about interventions against individuals who failed to adhere to COVID-19 norms. In this pre-registered study (N = 128), 4- to 7-year-olds heard stories about a norm violator, that is, a person who refuses to wear a mask in class (COVID condition) or wear indoor shoes in class when his or her shoes are muddy (Muddy Shoes condition). Children evaluated four different interventions-giving a mask/indoor shoes (Giving), preventing the person from entering (Exclusion), throwing a paper ball at the person (Throwing), and not intervening (Doing Nothing)-in terms of their rightness, niceness, and effectiveness. We found that across measures children evaluated Giving most positively, whereas they viewed Throwing most negatively. Doing Nothing and Exclusion received mixed evaluations across measures, revealing nuanced judgments of these interventions in children. In most measures, there was no difference between the COVID and Muddy Shoes conditions, suggesting that children's evaluations are not specific to the novel COVID-19 context. Together, our results show that children dynamically evaluate each intervention, taking multiple factors into account. The current study has implications for the development of interventions against norm violations.

Clinicopathological characteristics of light chain proximal tubulopathy in Korean patients and the diagnostic usefulness of immunohistochemical staining for immunoglobulin light chain.

BACKGROUND: Light chain proximal tubulopathy (LCPT) is a rare paraproteinemic renal disease that has been mostly reported in Western patients. LCPT is characterized by the accumulation of immunoglobulin (Ig)-light chain (LC) in the proximal tubule. Immunohistochemical staining for Ig-LC has not been investigated in the context of LCPT. We reported the clinicopathological characteristics and Ig-LC immunoexpression of patients with LCPT for the first time in Korea. METHODS: We reviewed the clinicopathological findings of 5 Korean patients diagnosed with LCPT between 2016 and 2018. In addition, immunohistochemical staining for κ-LC and λ-LC was conducted on paraffin-embedded tissues. RESULTS: The median age was 63 years, and the male-to-female ratio was 3:2. The primary renal manifestations were either azotemia or tubular proteinuria. All patients were diagnosed with multiple myeloma with monoclonal κ-LC (#1-2) or λ-LC (#3-5) in the serum and urine. Kidney biopsies revealed diverse and subtle alterations of the proximal tubule, including crystallization, vacuolization, and/or swelling. Electron microscopy revealed crystals in patients #1-2 and non-crystalline particles within numerous/large/dysmorphic lysosomes in patients #3-5. Ig-LC restriction was demonstrated in the proximal tubule as κ-type in patients #1-2 and as λ-type in patients #3-5 by immunohistochemistry and immunofluorescence. Immunohistochemical staining showed diffuse positivity to κ- and λ-LC, although immunofluorescent staining for κ-LC was focal and weak. LCPT has diverse clinicopathological characteristics and subtle morphological alterations, which necessitate ancillary tests for diagnosis. CONCLUSIONS: We introduced immunohistochemical staining for Ig-LC as a useful tool for the diagnosis of LCPT, especially in the case of κ-type crystals.

Exploring self-concept, wellbeing and distress in therapeutic songwriting participants following acquired brain injury: A case series analysis.

Acquired brain injury (ABI) presents a significant threat to sense of self and necessitates a complex process of psychosocial adjustment. Self-concept changes remain understudied in the early stages of inpatient rehabilitation. The aim of the current study was to examine changes in self-concept, distress, wellbeing and functional skills for five inpatients undertaking a music therapy intervention within a subacute rehabilitation centre in Victoria, Australia. Participants completed a six-week, 12-session therapeutic songwriting programme to produce past-, current- and future-self-focused songs. A range of self-concept, subjective wellbeing and distress measures were completed pre-, mid- and post-intervention. A descriptive case series approach was applied to determine trends in pre-post scores for five individual cases. Participants showing the greatest gains across self-concept and subjective wellbeing indices also showed the greatest functional gains on the Functional Independence Measure (FIM) from admission to discharge. The current study highlights the importance of examining early changes in self-concept, wellbeing and distress in subacute rehabilitation, and suggests that individualised songwriting programmes warrant further research attention in neurological populations.

A therapeutic songwriting intervention to promote reconstruction of self-concept and enhance well-being following brain or spinal cord injury: pilot randomized controlled trial.

OBJECTIVE: To determine the size of the effects and feasibility (recruitment and retention rates) of a therapeutic songwriting protocol for in-patients and community-dwelling people with acquired brain injury or spinal cord injury. DESIGN: Randomized controlled trial with songwriting intervention and care-as-usual control groups, in a mixed measures design assessed at three time points. PARTICIPANTS: A total of 47 participants (3 in-patients with acquired brain injury, 20 community participants with acquired brain injury, 12 in-patients with spinal cord injury, and 12 community participants with spinal cord injury: 23 1208 days post injury). INTERVENTIONS: The intervention group received a 12-session identity-targeted songwriting programme, where participants created three songs reflecting on perceptions of past, present, and future self. Control participants received care as usual. MEASURES: Baseline, postintervention, and follow-up measures comprised the Head Injury Semantic Differential Scale (primary outcome measure), Patient Health Questionnaire-9, Emotion Regulation Questionnaire, and Satisfaction with Life Scale. RESULTS: No significant between group pre-post intervention differences were found on the primary self-concept measure, the Head Injury Semantic Differential Scale ( p = 0.38, d = 0.44). Significant and large effect sizes from baseline to post between groups in favour of the songwriting group for Satisfaction with Life ( p = 0.04, n2 p = 0.14). There were no significant between group pre-post interaction effects for the Emotion Regulation Suppression subscale ( p = 0.12, n2 p = -0.08) although scores decreased in the songwriting group over time while increasing for the standard care group. There were no significant differences in baseline to follow-up between groups in any other outcome measures. Recruitment was challenging due to the small number of people eligible to participate combined with poor uptake by eligible participants, particularly the in-patient group. Retention rates were higher for the community-dwelling cohorts. CONCLUSION: This study demonstrates the challenges in recruitment and retention of participants invited to participate in a music therapy study. Findings suggest this identity-focused therapeutic songwriting protocols may be more beneficial for people who have transitioned from in-patient to community-contexts given the greater proportion of participants who consent and complete the intervention. Preliminary effects in favour of the intervention group were detected in a range of well-being measures suggesting that a larger study is warranted.

Bidirectional examination of the interaction between time and numerosity corroborates that numerosity influences time estimation but not vice versa.

There has been great interest in the idea that time, number, and space share a common magnitude system. However, only a handful of studies examined bidirectional interaction between time and number and the results varied depending on the specifics of the methods and stimulus properties of each study. The present study investigated bidirectional interaction between time and number using estimation tasks. We used duration (Experiment 1) and numerosity (Experiment 2) estimation tasks to investigate the effect of numerosity-on-duration and duration-on-numerosity estimation. The results from the two experiments demonstrated that numerosity influences duration processing but not vice versa; that is, there was unidirectional interaction between numerosity and time. The duration of stimulus presentation was overestimated for stimuli larger in (task-irrelevant) numerosity. Possible mechanisms underlying the unidirectional interaction between time and number are discussed.

Lead exposure may affect gingival health in children.

BACKGROUND: Several studies have reported the harmful effects of lead poisoning. However, the relationship between lead exposure and oral health of children has not been well defined. The aim of this study was to investigate the relationship between blood lead level (BLL) and oral health status of children. METHODS: A total of 351 children (aged 7-15 years) were recruited from the pilot data of the Korean Environmental Health Survey in Children and Adolescents, which was designed to examine environmental exposure and children's health status in South Korea. Blood samples were taken to determine BLLs and oral examinations were performed to assess oral health parameters, including community periodontal index (CPI), gingival index (GI), and plaque index (PI). Information regarding socioeconomic status, oral hygiene behavior, and dietary habits was collected from parents and guardians. RESULTS: The participants were divided equally into four quartiles, with quartile I comprised of children with the lowest BLLs. There were significant differences for PI (p < 0.05) among the quartile groups. Using logistic regression models, we found a significant relationship between BLL and oral health parameters. The crude odds ratios for CPI, GI, and PI in the third quartile were 5.24 (95% CI: 1.48-18.56), 4.35 (95% CI: 1.36-13.9), and 4.17 (95% CI: 1.50-11.54), respectively, while the age and gender-adjusted odds ratios were 7.66 (95% CI: 1.84-31.91), 6.80 (95% CI: 1.80-25.68), and 3.41 (95% CI: 1.12-10.40), respectively. After adjustments for age, gender, parent education level, and frequency of tooth brushing, the adjusted odds ratios were 7.21 (95% CI: 1.72-30.19), 6.13 (95% CI: 1.62-23.19), and 3.37 (95% CI: 1.10-10.34), respectively. CONCLUSIONS: A high BLL might be associated with oral health problems in children, including plaque deposition and gingival diseases.

RASD1 Knockdown Results in Failure of Oocyte Maturation.

BACKGROUND: Ras dexamethasone-induced protein (RASD1) is a member of Ras superfamily of small GTPases. RASD1 regulates various signaling pathways involved in iron homeostasis, growth hormone secretion, and circadian rhythm. However, RASD1 function in oocyte remains unknown. METHODS: Using immunohistochemistry, immunofluorescence, and quantitative real-time RT-PCR, RASD1 expression in mouse ovary and RASD1 role in oocyte maturation-related gene expression, spindle formation, and chromosome alignment were analyzed. RNAi microinjection and time-lapse video microscopy were used to examine the effect of Rasd1 knockdown on oocyte maturation. RESULTS: RASD1 was highly detected in oocytes transitioning from primordial to secondary follicles. Rasd1 was highly expressed in germinal vesicle (GV), during GV breakdown, and in metaphase I (MI) stage as oocytes mature, and its expression was significantly downregulated in MII stage. With knockdown of Rasd1, maturation in GV oocytes was arrested at MI stage, showing disrupted meiotic spindling and chromosomal misalignment. In addition, Obox4 and Arp2/3, engaged in MI-MII transition and cytokinesis, respectively, were misregulated in GV oocytes by Rasd1 knockdown. CONCLUSION: These findings suggest that RASD1 is a novel factor in MI-MII oocyte transition and may be involved in regulating the progression of cytokinesis and spindle formation, controlling related signaling pathways during oocyte maturation.

Melatonin prevents cisplatin-induced primordial follicle loss via suppression of PTEN/AKT/FOXO3a pathway activation in the mouse ovary.

Premature ovarian failure (POF) is a major side effect of chemotherapy in young cancer patients. To develop pharmaceutical agents for preserving fertility, it is necessary to understand the mechanisms responsible for chemotherapy-induced follicle loss. Here, we show that treatment with cisplatin, a widely used anticancer drug, depleted the dormant follicle pool in mouse ovaries by excessive activation of the primordial follicles, without inducing follicular apoptosis. Moreover, we show that co-treatment with the antioxidant melatonin prevented cisplatin-induced disruption of the follicle reserve. We quantified the various stages of growing follicles, including primordial, primary, secondary, and antral, to demonstrate that cisplatin treatment alone significantly decreased, whereas melatonin co-treatment preserved, the number of primordial follicles in the ovary. Importantly, analysis of the PTEN/AKT/FOXO3a pathway demonstrated that melatonin significantly decreased the cisplatin-mediated inhibitory phosphorylation of PTEN, a key negative regulator of dormant follicle activation. Moreover, melatonin prevented the cisplatin-induced activating phosphorylation of AKT, GSK3ß, and FOXO3a, all of which trigger follicle activation. Additionally, we show that melatonin inhibited the cisplatin-induced inhibitory phosphorylation and nuclear export of FOXO3a, which is required in the nucleus to maintain dormancy of the primordial follicles. These findings demonstrate that melatonin attenuates cisplatin-induced follicle loss by preventing the phosphorylation of PTEN/AKT/FOXO3a pathway members; thus, melatonin is a potential therapeutic agent for ovarian protection and fertility preservation during chemotherapy in female cancer patients.

Overexpression of malic enzyme in the larval stage extends Drosophila lifespan.

Metabolic modifications during the developmental period can extend longevity. We found that malic enzyme (Men) overexpression during the larval period lengthened the lifespan of Drosophila. Men overexpression by S106-GeneSwitch-Gal4 driver increased pyruvate content and NADPH/NADP(+) ratio but reduced triglyceride, glycogen, and ATP levels in the larvae. ROS levels increased unexpectedly in Men-overexpressing larvae. Interestingly, adults exposed to larval Men-overexpression maintained ROS tolerance with enhanced expression levels of glutathione-S-transferase D2 and thioredoxin-2. Our results suggest that metabolic changes mediated by Men during development might be related to the control of ROS tolerance and the longevity of Drosophila.

Outcomes of endovascular abdominal aortic aneurysm repair in high-risk patients.

OBJECTIVE: Although the endovascular aneurysm repair trial 2 (EVAR-2) demonstrated no benefit of EVAR in high-risk (HR) patients, EVAR is still performed widely in this patient cohort. This study compares the midterm outcomes after EVAR in HR patients with those in normal-risk (NR) patients. In turn, these data are compared with the EVAR-2 data. METHODS: A retrospective review from January 2006 to December 2013 identified 247 patients (75 HR [30.4%], 172 NR [69.6%]) who underwent elective EVAR for infrarenal aortic aneurysm in an academic tertiary institution and its affiliated Veterans Administration hospital. The same HR criteria used in the EVAR-2 trial were employed. Overall survival, graft-related complications, and reintervention rates were estimated by the Kaplan-Meier method. HR group outcomes were compared with the EVAR-2 data. RESULTS: HR patients had a larger abdominal aortic aneurysm size and had a higher prevalence of cardiac disease (P < .01), chronic obstructive pulmonary disease (P = .02), renal insufficiency (P < .01), and cancer (P < .01). Use of aspirin (63% HR vs 66% NR; P = .6), statin (83% HR vs 72% NR; P = .2), and beta-blockers (71% HR vs 60% NR; P = .2) was similar; in the EVAR-2 trial, the corresponding use of these medications was 58%, 42%, and not available, respectively. Perioperative mortality (0% HR vs 1.2% NR; P = 1.0) and early complication rates (4% HR vs 6% NR; P = .8) were similar. In contrast, perioperative mortality in the EVAR-2 trial was 9%. At a mean follow-up of 3 years, the incidence rates of delayed secondary interventions for aneurysm- or graft-related complications were 7% for HR patients and 10% for NR patients (P = .5). The 1-, 2-, and 4-year survival rates in HR patients (85%, 77%, 65%) were lower than those in NR patients (97%, 97%, 93%; P < .001), but this was more favorable compared with a 36% 4-year survival in the EVAR-2 trial. No difference was seen in long-term reintervention-free survival in HR and NR patients (P = .8). Backward stepwise logistic regression analysis identified five prognostic indicators for post-EVAR death: age, chronic kidney disease stages 4 and 5, congestive heart failure, home oxygen use, and current cancer therapy. CONCLUSIONS: EVAR can be performed in patients unfit for open surgical repair with excellent early survival and long-term durability. These outcomes in the HR group compare more favorably to the EVAR-2 trial data. However, not all HR patients for open surgical repair derive the benefit from EVAR. The decision to proceed with EVAR in HR patients should be individualized, depending on the number and severity of risk factors.

Effects of exercise on glycemic control in type 2 diabetes mellitus in Koreans: the fifth Korea National Health and Nutrition Examination Survey (KNHANES V).

[Purpose] The aim of this study was to investigate the effect of exercise on glycemic control using data from fifth Korea National Health and Nutrition Examination Survey and to provide appropriate exercise guidelines for patients with type 2 diabetes mellitus in Korea. [Subjects and Methods] We selected 1,328 patients from the fifth Korea National Health and Nutrition Examination Survey database who had type 2 diabetes and ranged in age from 30 to 90 years. Statistical analyses included χ(2) tests, multiple linear regression, and logistic regression. [Results] Factors found to be significantly related to glycemic control included income level, physical activity based on intensity of aerobic exercise, use of diabetes medicine, presence of hypertension, duration of diabetes, and waist circumference. In addition, engaging in combined low- and moderate-intensity aerobic exercise when adjusted for resistance exercise was found to lower the risk of glycemic control failure. [Conclusion] Patients with type 2 diabetes mellitus in Korea should engage in combined low- and moderate-intensity aerobic exercise such as walking for 30 minutes or more five times a week. Physical activity is likely to improve glycemic control and thus prevent the acute and chronic complications of diabetes mellitus.

Characterization of p-hydroxycinnamate catabolism in a soil Actinobacterium.

p-Hydroxycinnamates, such as ferulate and p-coumarate, are components of plant cell walls and have a number of commercial applications. Rhodococcus jostii RHA1 (RHA1) catabolizes ferulate via vanillate and the ß-ketoadipate pathway. Here, we used transcriptomics to identify genes in RHA1 that are upregulated during growth on ferulate versus benzoate. The upregulated genes included three transcriptional units predicted to encode the uptake and ß-oxidative deacetylation of p-hydroxycinnamates: couHTL, couNOM, and couR. Neither ΔcouL mutants nor ΔcouO mutants grew on p-hydroxycinnamates, but they did grow on vanillate. Among several p-hydroxycinnamates, CouL catalyzed the thioesterification of p-coumarate and caffeate most efficiently (k(cat)/K(m) = ∼ 400 mM(-1) s(-1)). p-Coumarate was also RHA1's preferred growth substrate, suggesting that CouL is a determinant of the pathway's specificity. CouL did not catalyze the activation of sinapate, in similarity to two p-coumaric acid:coenzyme A (CoA) ligases from plants, and contains the same bulged loop that helps determine substrate specificity in the plant homologues. The couO mutant accumulated 4-hydroxy-3-methoxyphenyl-ß-ketopropionate in the culture supernatant when incubated with ferulate, supporting ß-oxidative deacetylation. This phenotype was not complemented with a D257N variant of CouO, consistent with the predicted role of Asp257 as a metal ligand in this amidohydrolase superfamily member. These data suggest that CouO functionally replaces the ß-ketothiolase and acyl-CoA thioesterase that occur in canonical ß-oxidative pathways. Finally, the transcriptomics data suggest the involvement of two distinct formaldehyde detoxification pathways in vanillate catabolism and identify a eugenol catabolic pathway. The results of this study augment our understanding of the bacterial catabolism of aromatics from renewable feedstocks.

Environmental exposure to lead (Pb) and variations in its susceptibility.

Based on exposure frequency and intrinsic toxicity, lead (Pb) ranks one of the highest priority toxic materials. Continuous regulation of environmental Pb exposure has contributed to dramatically diminished exposure levels of Pb, for example, blood level of Pb. However, the safety level of Pb is not established, as low-level exposure to Pb still shows severe toxicity in high susceptible population and late onset of some diseases from early exposure. In the present study, we focused on food-borne Pb exposure and found broad variations in Pb exposure levels via food among countries. In addition, there are genetic or ethnical variations in Pb-targeted and protective genes. Moreover, various epigenetic alterations were induced by Pb poisoning. Therefore, we suggest a systemic approach including governmental (public) and individual prevention from Pb exposure with continuous biological monitoring and genetic or epigenetic consideration.

Childcare sharing and family happiness: analyzing parental and child well-being in the actor-partner interdependence model.

Introduction: The exploration of the relationship between parental and child happiness, particularly in the context of shared childcare responsibilities, has not been examined in Korean families. Methods: Using a two-wave longitudinal design and data from 1,403 families from the Panel Study on Korean Children, this study employed the actor-partner interdependence model to examine the dynamics of childcare sharing between mothers and fathers in South Korea. Results: Mothers' childcare sharing was found to have no significant impact on their own and their partner's happiness, reflecting traditional gender norms that undervalue mothers' contributions. In contrast, fathers' childcare sharing had a positive impact on their own and their spouse's happiness, suggesting a growing recognition of fathers' involvement. Furthermore, fathers' active participation in childcare was found to promote their children's happiness through their own happiness. Discussion: This study reflects the complexity of evolving family roles and the covert persistence of traditional gender roles in modern Korean parenting. It suggests the importance of work and family policies that support changes in family dynamics by providing a more nuanced understanding of how changing family roles and responsibilities can enhance overall family well-being.

Children's third-party punishment does not change depending on the prospect of future interaction.

Children pay a cost to punish third parties for unfairness. However, theoretical debates highlight that such behaviors could reflect a strategic attempt to manipulate others in future interactions. The personal deterrence hypothesis claims that punishment is motivated to deter future unfairness toward punishers. Here we tested this hypothesis with a total of n = 248 five- to 10-year-olds. In two experiments, participants witnessed that a divider shared resources either fairly or selfishly with a third party. Participants learned that the same divider (same divider condition) or a new divider (different divider condition) would subsequently decide how to share resources with the participant. If children's punishment is motivated by personal deterrence, they should punish unfairness more often in the same divider condition (vs. different divider). Conversely, if children fear retaliation from dividers, they should punish dividers less often in the same divider condition (vs. different divider). Children intervened by taking resources away from the divider (Experiment 1) or by sending a disapproving or an approving verbal message (Experiment 2). Children were more likely to punish unfair than fair allocations through material punishment and disapproving messages, while being more likely to reward fair than unfair allocations by sending approving messages. However, children did so at the same level regardless of their future divider's identity. We discuss how these results speak to a children's emerging concern with fairness and how it challenges the notion that children punish for self-oriented reasons as suggested by the personal deterrence hypothesis.

Treatment compliance, treatment patterns, and healthcare utilization in epilepsy patients with first add-on antiepileptic drugs: A nationwide cohort study.

Objective: This study aimed to assess the treatment compliance, patterns, healthcare resource utilization (HCRU), and costs of anti-epilepsy drugs (AEDs) as the first add-on therapy in patients with epilepsy. Methods: We conducted a retrospective population-based cohort study using Korean National Health Insurance claims data from 2016 to 2020. Patients with epilepsy who newly received AED add-on therapy were identified and followed for up to 12 months to evaluate persistence, adherence, treatment patterns, HCRU, and costs. Results: Among 6,746 patients who initiated AED add-on therapy, 65.5% were persistent on their index AED add-on from the index date until the end of the follow-up period, and the mean persistent time on the index add-on was 307.3 ± 92.3 days. A total of 76.8% patients were adherent, with a medication possession ratio (MPR) ≥80%, and the mean MPR was 88.9 ± 25.4%. Persistence and adherence to the index AED add-on were relatively higher among patients prescribed lamotrigine, levetiracetam, oxcarbazepine, and perampanel than those prescribed carbamazepine, topiramate, or valproate. A total of 41.0% of the patients changed their index AED add-on during the follow-up period. The carbamazepine, topiramate, and valproate groups had higher rates of change than the other AED groups. HCRU and costs tended to be lower in the lamotrigine, levetiracetam, oxcarbazepine, and perampanel groups. Furthermore, perampanel showed the lowest HCRU and costs for all-cause cases as well as the lowest length of stay and outpatient visits for epilepsy-related cases. Conclusion: In this population-based study, the use of lamotrigine, levetiracetam, oxcarbazepine, or perampanel as the first add-on therapy in patients with epilepsy contributed to better treatment compliance and lower HCRU and costs than that of carbamazepine, topiramate, or valproate.

One-Step Detection of Vancomycin in Whole Blood Using the Lateral Flow Immunoassay.

Vancomycin (VAN) is an effective antibiotic against Gram-positive bacteria and the first-line therapy to prevent and treat methicillin-resistant Staphylococcus aureus (MRSA) and severe infections. However, low concentrations of VAN can result in resistant strains. High doses of VAN can cause nephrotoxicity and ototoxicity; thus, VAN is a representative drug for which drug monitoring is recommended. Several methods have been proposed to detect VAN. Among them, lateral flow immunoassays (LFIAs) have advantages, such as simple and user-friendly operation, low sample volume requirement, and cost effectiveness. In this study, we developed an LFIA capable of rapid on-site detection such that the VAN concentration in plasma could be monitored within 20 min by a one-step detection process using whole blood without plasma separation. VAN can be detected in whole blood over a wide range of concentrations (20-10,000 ng/mL), and the LFIA reported here has a detection limit of 18 ng/mL. The applicability of the developed LFIA compared to the results of measuring VAN with a commercial enzyme-linked immunosorbent assay kit showed a satisfactory correlation (Spearman's rho, ρ = 0.891). Therefore, the developed LFIA enables rapid and wide-range VAN detection in whole blood and can aid in drug monitoring to evaluate patients' responses to treatment.
