Background: Previous research shows that socioeconomic status (SES) positively impacts children's development, yet the benefits are not equally distributed across racial groups. According to the Minorities' Diminished Returns (MDRs) framework, Black children tend to experience smaller gains from parental education compared to White children.
Objective: Building on the MDRs framework, this study examines whether high financial strain contributes to the diminished returns of parental education for Black children, using data from the Adolescent Brain Cognitive Development (ABCD) Study.

Objective: This study aims to identify the risk factors for systemic inflammatory response syndrome (SIRS) after minimally invasive percutaneous nephrolithotomy (PCNL) with a controlled irrigation pressure and to find which patients undergoing PCNL are likely to develop SIRS under the pressure-controlled condition.
Methods: A total of 303 consecutive patients who underwent first-stage PCNL in our institute between July 2016 and June 2018 were retrospectively reviewed. All the procedures were performed with an 18 F tract using an irrigation pump setting the irrigation fluid pressure at 110 mmHg and the flow rate of irrigation at 0.

Background: Illicit cigarette consumption (ICC) results in cheaper cigarettes and lost tax revenue. Although several methods estimate the ICC proportion, the one based on cigarette butt (CB), the most littered item worldwide, is less common. This study aimed at estimating the ICC proportion of Guarujá, a major Brazilian city, based on littered CBs.

Introduction: Maternal undernutrition and inflammation in utero may significantly impact the neurodevelopmental potential of offspring. However, few studies have investigated the effects of pregnancy interventions on long-term child growth and development. This study will examine the effects of prenatal nutrition and infection management interventions on long-term growth and neurodevelopmental outcomes of offspring.

Introduction: Serum cystatin C (CysC) is used to estimate glomerular filtration rate (eGFR), including in the Chronic Kidney Disease in Children (CKiD) Under 25 years (U25eGFR) equations. Several CysC measurement procedures available from diagnostic vendors include reference material for calibration, but the extent of heterogeneity across manufacturers is unclear. Since heterogeneity may have clinical and research implications for eGFR, we evaluated three CysC procedures in samples from the CKiD study representing a wide spectrum of kidney function.

Background And Objectives: Blood-based biomarkers of amyloid and tau have been shown to predict Alzheimer disease (AD) dementia. Much less is known about their ability to predict risk of mild cognitive impairment (MCI), an earlier disease stage. This study examined whether levels of blood biomarkers of amyloid (Aβ/Aβ ratio), tau (p-tau), neurodegeneration (NfL), and glial activation and neuroinflammation (glial fibrillary acidic protein [GFAP], YKL40, soluble triggering receptor expressed on myeloid cells 2 [sTREM2]) collected when participants were cognitively normal are associated with the time to onset of MCI.

Background: This study examined the relationship between neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) and cognition in people living with HIV (PLWH) at baseline and over time.
Methods: Plasma and clinical data were available from PLWH aged ≥45 years with HIV RNA <200 copies/mL enrolled in the AIDS Clinical Trials Group HAILO cohort study. We measured plasma NfL and GFAP using a single molecule array platform.

Many trials are designed to collect outcomes at or around pre-specified times after randomization. If there is variability in the times when participants are actually assessed, this can pose a challenge to learning the effect of treatment, since not all participants have outcome assessments at the times of interest. Furthermore, observed outcome values may not be representative of all participants' outcomes at a given time.

Aim: To comprehensively evaluate the benefits and risks of glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl peptidase 4 inhibitors (DPP4i), and sodium-glucose cotransporter 2 inhibitors (SGLT2i).
Materials And Methods: A systematic search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 2023 to identify randomized cardiovascular and kidney outcome trials that enrolled adults with type 2 diabetes, heart failure, or chronic kidney disease and compared DPP4i, GLP-1RAs, or SGLT2i to placebo. Twenty-one outcomes (e.
Background: Tobacco taxes are a powerful tool for reducing tobacco consumption and a reliable source of revenue for government.
Aim: To investigate the potential efficacy of tobacco taxation strategies in Jordan in relation to their fiscal and health-related outcomes.
Methods: Using Tobacconomics, we conducted a comparative analysis of several taxation scenarios: maintaining the status quo; increasing both specific excise and tiered taxes; increasing tiered tax rates alone; and raising specific excise taxes only.

Objective: To evaluate the impact of tort reform laws passed in 2011 capping noneconomic damages in North Carolina and Tennessee on rates and adjusted per user costs of tests, imaging, and procedures in the Medicare fee-for-service population.
Study Setting And Design: State-level synthetic difference-in-differences, adjusting for the percent of FFS Medicare beneficiaries in the state who were female, had ever been on Medicare Advantage, were eligible for Medicaid for at least 1 month of the year, and total state risk-adjusted, standardized per-capita costs. Analyses of North Carolina and Tennessee were performed separately.

Background: Women's economic empowerment (WEE) is believed to reduce the risk of intimate partner violence (IPV), yet the relationship between WEE and IPV has proven to be highly variable. Little attention has been given to how the normative WEE environment may influence this relationship across different settings. This study tests whether IPV is associated with Vanguard WEE, defined as individual economic participation that deviates from community norms.

Objective: Intimate partner violence (IPV) affects an estimated 47% of women living in the USA in their lifetime and is associated with increased risk of physical and mental health concerns. Current prevention efforts focus on individual and family-level interventions rather than macrosystem-level policies. Thus, we sought to test the effects of Medicaid expansion on the rates of IPV and violence more broadly.

The infant brain undergoes rapid developmental changes in the first three years of life. Understanding these changes through the prediction of chronological age using neuroimaging can provide insights into typical and atypical brain development. We utilized 938 resting-state EEG recordings from 457 typically developing infants, 2 to 38 months old, to develop age prediction models.

Objectives: To estimate levels of person-centered contraceptive counseling among current and recent contraceptive users, assess for whom counseling differs, and examine the relationship between counseling and contraceptive practices, specifically use of provider-dependent methods and use of one's preferred method, among women in Ethiopia.
Study Design: This cross-sectional study uses nationally representative data collected by the Performance Monitoring for Action Ethiopia project among current and recent contraceptive users ( = 2731) aged 15-49 between October and November 2021. Descriptive analyses estimated person-centered counseling levels via the recently validated quality of contraceptive counseling short scale (QCC-10).

Background: The impact of pre-infection vaccination on the risk of long COVID remains unclear in the pediatric population. We aim to assess the effectiveness of BNT162b2 on long COVID risks with various strains of the SARS-CoV-2 virus in children and adolescents, using comparative effectiveness methods. We further explore if such pre-infection vaccination can mitigate the risk of long COVID beyond its established protective benefits against SARS-CoV-2 infection using causal mediation analysis.
