Concentrations of Lead and Arsenic in Mother's Milk and Children's Blood in Peruvian Breastfeeding Dyads.

BACKGROUND: Toxic trace elements could enter human milk through mothers' food consumption, drinking water, air, or incidental soil ingestion, and are of concern to the nursing infant. RESEARCH AIM: To determine the concentration of toxic trace elements (lead and arsenic) in Peruvian mothers' milk and their association with blood concentrations in their own infants 3-20 months old. METHOD: This exploratory, cross-sectional study, carried out in Peru, included breastfeeding mother/child dyads (N = 40). Following standardized protocols, biospecimens of human milk and child's blood were collected. RESULTS: Lead and arsenic concentrations in milk were above the method detection limits in 73% and 100% of samples with median concentrations of 0.26 µg/L (IQR = 0.10, 0.33 µg/L) and 0.73 µg/L (IQR = 0.63, 0.91 µg/L), respectively. Concentrations of lead and arsenic in blood were 2.05 µg/dL (SD = 1.35), and 1.43 µg/dl (geometric mean: SD = 1.39), respectively. Blood lead concentrations in 12.5% (n = 5) of the samples were above the U.S. Center for Disease Control and Prevention reference value (< 3.5 µg/dl), and over half of arsenic concentrations were above the acceptable levels of < 1.3 µg/dl (Mayo Clinic Interpretative Handbook). Our results showed that for every one-month increase in age, lead blood concentrations increased by 0.1 µg/dl (p = 0.023). Additionally, every 1 µg/L increase in the mother's milk arsenic was associated with a 1.40 µg/dl increase in the child's blood arsenic concentration. CONCLUSIONS: Implementing effective interventions to decrease the toxic exposure of reproductive-aged women is needed in Peru and worldwide.

A critical analysis of national plans for climate adaptation for health in South America.

Climate adaptation measures are critical for protecting human health. National Adaptation Plans (NAPs), Nationally Determined Contributions (NDCs), and National Communications (NCs) play a crucial role in helping countries identify, analyze, and address their vulnerabilities to climate change impacts, while also assessing available resources and capacities. This study aimed to assess the comprehensiveness of South American countries' NAPs, NDCs, and NCs in addressing the effects of climate change on health. A total of 38 NAPs, NDCs, and NCs of 12 South American countries were analysed. Ad hoc scores were developed to assess baseline information, adaptation proposals, identification of involved institutions, funding needs and allocation, measurable progress indicators, and coherence. Overall, all South American countries have NDCs and NCs, and seven have NAPs. In most countries, the intersectoral health analysis revealed a lack of linkage to health issues related to that sector. Additionally, most planning documents lack detailed information to guide policymakers in taking practical actions; areas with low scores include allocation of funds, involvement of health-related institutions, and measurable indicators. While South American countries acknowledge the health impacts of climate change in their plans, enhancing public health protection requires maximizing climate policy benefits and including health-related issues across all relevant sectors. Funding: This study was not funded. However, three co-authors received funding for some of their time: AV and KC were supported by the Wellcome Trust (209734/Z/17/Z); RCN was funded by K01AI139284 (NIH-NIAID).

Effectiveness of individualized counseling on the duration of exclusive breastfeeding: study protocol for a multicenter, randomized, parallel, and open clinical trial.

BACKGROUND: Despite the benefits of breastfeeding, early weaning is a reality, so less than 50% of children worldwide and in Brazil are on exclusive breastfeeding in the sixth month of life. A strategy to counteract this scenario is breastfeeding counseling. This study aims to verify the effectiveness of individualized counseling by nurses trained in breastfeeding counseling, on the duration of exclusive breastfeeding, compared to standard care. METHODS: Multicenter, randomized, parallel, and open clinical trial, with primiparous women aged over 18 years, hospitalized in rooming-in wards at participating centers and hemodynamically stable, aware, and oriented, who had a single-fetus pregnancy and gave birth, regardless of the type of delivery, with live child, gestational age of 37 to 42 weeks and birth weight greater than 2500 g. The women will be initially approached in rooming-in wards and, upon consent to participate in the study, will be allocated through randomization by blocks composed of eight participants in two groups: intervention and control. The randomization lists will be organized by a central without involvement with the study, which will manage the allocation groups and be prepared in the Randon® program. Women allocated to the intervention group will receive breastfeeding counseling by trained nurses, and those in the control group will receive standard care at the center participating in the study. DISCUSSION: The results can contribute to breastfeeding by evidencing possible exclusivity and duration of the counseling trained nurses provide.

Hospital Adhering to the Ten Steps to Successful Breastfeeding Predicts Exclusive Breastfeeding in Latinx Mothers.

Introduction: Assessing how well a hospital adheres to the Ten Steps to Successful Breastfeeding is the key to outlining necessary modifications in mother breastfeeding support. This study aimed to assess Latinx mothers' perception of how well a hospital adheres to the Ten Steps to Successful Breastfeeding and its influence on exclusive breastfeeding (EBF) rates at hospital discharge. Methods: Secondary analysis of two longitudinal studies. The combined sample (N = 74) of Latinx pregnant women residing in the US. We modified, translated, and evaluated reliability of the Questionnaire for the Breastfeeding Mother (QBFM), which was applied to evaluate mothers' perception of how well a hospital adheres to the Ten Steps to Successful Breastfeeding. Results: The QBFM obtained a standardized KR-20 of 0.77. Mothers who EBF had higher scores of the QBFM than mothers who used formula during hospitalization. For each point that the QBFM score increased, the likelihood that the mother was EBF at discharge increased by 1.30 times. Conclusion: Mothers' perceptions of how well a hospital adheres to the Ten Steps to Successful Breastfeeding were the only significant variable associated with EBF at discharge. The QBFM Spanish version is a valuable instrument that can be used to obtain measurable outcomes and outlines necessary changes after implementing the Ten Steps to Successful Breastfeeding.

Prática dos profissionais da saúde em aleitamento materno e fatores associados: estudo transversal / Health professionals' breastfeeding practices and associated factors: a cross-sectional study

OBJETIVO: Analisar a prática dos profissionais da saúde da atenção básica quanto ao aleitamento materno e fatores associados. MÉTODO: Estudo transversal, analítico, realizado com todos os profissionais da saúde atuantes em aleitamento materno de cinco unidades da atenção básica através de questionário autoaplicável. Para análise da associação das variáveis categóricas com a prática profissional, utilizou-se teste Qui-quadrado com nível de significância de 5%. RESULTADOS: Participaram 38 profissionais. Houve associação estatística significativa (p=0.04597) entre a variável atualização em aleitamento materno nos últimos cinco anos e a prática de implementação em grupos de apoio. O manejo clínico, a orientação quanto aos direitos maternos e o apoio para a resolução de dificuldades na amamentação foram menos informados. CONCLUSÃO: A prática dos profissionais da saúde apresentou fragilidades evidenciando a necessidade de valorização do tema por profissionais e gestores através de estratégias que incluam capacitação contínua e monitoramento do aleitamento materno na rede de atenção básica.

OBJECTIVE: To analyze primary care health professionals' breastfeeding practices and associated factors. METHOD: A cross-sectional and analytical study was carried out with all health professionals working in breastfeeding support in five primary healthcare units, through a self-administered questionnaire. The chi-square test was used with a significance level of 5% to analyze the association of categorical variables with professional practice. RESULTS: Thirty-eight professionals participated. There was a statistically significant association (p=0.04597) between the variable update on breastfeeding in the last five years and the practice of implementing breastfeeding through support groups. Clinical management, guidance on maternal rights, and support for resolving difficulties in breastfeeding were less reported. CONCLUSION: The practice of health professionals showed weaknesses, highlighting the need for professionals and managers to value the breastfeeding issue through strategies that include continuous training and monitoring of breastfeeding in the primary healthcare network.

School connectedness mediates the association of social function with depressive symptoms in teenagers with attention deficit hyperactivity disorder.

BACKGROUND: Depressive symptoms commonly co-occur in teenagers with attention deficit hyperactivity disorder (ADHD), and poor social function is a known predictor of depressive symptoms. This study's purpose was to determine whether school connectedness mediates the association between social function and depressive symptoms in teenagers with ADHD. METHOD: In this secondary analysis, we selected 313 (74%) of 425 teenagers with ADHD (male 72%, mean age = 15 years) who had completed data on depressive symptoms, social function, and school connectedness in the Fragile Families and Child Well-Being Study. The mediation effect of school connectedness was tested by multiple regression using SPSS PROCESS macro with 5000 bootstrap samples controlling covariates (teenagers' age, gender, and race, their relationship with primary caregivers, type of school teenager attends, time of living with primary caregivers, and primary caregivers' education). RESULTS: Social function predicted depressive symptoms (direct effect = -0.132, 95% CI = -0.218, -0.045). School connectedness mediated the relationship between social function and depressive symptoms (indirect effect = -0.084; 95% CI = -0.130, -0.045). CONCLUSION: This study points to the importance of considering school factors in understanding depression symptoms in children with ADHD. Also, clinicians should consider asking teenagers about school-related factors such as school connectedness which is likely important in understanding the experience of depressive symptoms in this population. Identifying ways to help enhance school connectedness for young people with ADHD should be prioritized.

CyTOF analysis identifies unusual immune cells in urine of BCG-treated bladder cancer patients.

High grade non-muscle-invasive bladder tumours are treated with transurethral resection followed by recurrent intravesical instillations of Bacillus Calmette Guérin (BCG). Although most bladder cancer patients respond well to BCG, there is no clinical parameter predictive of treatment response, and when treatment fails, the prognosis is very poor. Further, a high percentage of NMIBC patients treated with BCG suffer unwanted effects that force them to stop treatment. Thus, early identification of patients in which BCG treatment will fail is really important. Here, to identify early stage non-invasive biomarkers of non-responder patients and patients at risk of abandoning the treatment, we longitudinally analysed the phenotype of cells released into the urine of bladder cancer patients 3-7 days after BCG instillations. Mass cytometry (CyTOF) analyses revealed a large proportion of granulocytes and monocytes, mostly expressing activation markers. A novel population of CD15+CD66b+CD14+CD16+ cells was highly abundant in several samples; expression of these markers was confirmed using flow cytometry and qPCR. A stronger inflammatory response was associated with increased cell numbers in the urine; this was not due to hematuria because the cell proportions were distinct from those in the blood. This pilot study represents the first CyTOF analysis of cells recruited to urine during BCG treatment, allowing identification of informative markers associated with treatment response for sub-selection of markers to confirm using conventional techniques. Further studies should jointly evaluate cells and soluble factors in urine in larger cohorts of patients to characterise the arms of the immune response activated in responders and to identify patients at risk of complications from BCG treatment.

Social Health Care Determinants of Breastfeeding Black Women: A Multigenerational Study.

Background: Black women encounter many challenges to breastfeeding, including inequitable access to support and resources and medical racism. However, limited research investigates how Black women across generations interface with health care systems to initiate or continue breastfeeding and what factors facilitate or hinder their breastfeeding experiences. Objective: Using the social determinants of health (SDoH) theoretical framework, this study qualitatively explored how a multigenerational sample of Black mothers' interactions with health care systems facilitated or hindered their breastfeeding initiation and continuation. There were three areas of interest: (1) access and quality, (2) professional and personal support, and (3) literacy and resources. Materials and Methods: Four age cohorts and three breastfeeding length cohorts of Black mothers in Kentucky completed semi-structured interviews on their breastfeeding experiences. Responses to research questions (e.g., "What was your experience during the birthing process and how did it impact your decision to breastfeed?") informed by the SDoH were analyzed using thematic analysis. Results: Four themes emerged on how experiences within health care systems influence Black women's breastfeeding initiation and continuation: (1) health care access, (2) health care quality/bias, (3) health care-related support, and (4) health care resource use. Conclusions: Interpersonal and systemic barriers in health care related to access, quality, support, and resources hindered Black mother's breastfeeding across generations. Mothers across each age and breastfeeding cohorts emphasized a need for culturally tailored pro-breastfeeding health care systems to meet their breastfeeding needs.

Experiences of ethnic discrimination and COMT rs4680 polymorphism are associated with depressive symptoms in Latinx adults at risk for cardiovascular disease.

BACKGROUND: Ethnic discrimination is frequently experienced among U.S. Latinx communities, and is linked to CVD risk factors, such as depression. Genetic variants may influence this relationship. OBJECTIVES: The objectives of this study were to examine associations between experiences of discrimination, rs4680 genotype, and depressive symptoms in Latinx adults. METHODS: We analyzed data from 124 Latinx adults with two or more CVD risk factors, and conducted hierarchical linear regression, adjusting for sex, age, income, education, and acculturation. RESULTS: Participants were predominately female (74.2%) and aged 40.2 ± 9.3 years. More experiences of discrimination were associated with higher depressive symptoms (p = 0.041). Those with Met-Met-and Val-Met-genotypes had increased depressive symptoms than those with Val-Val-genotype (p = 0.049). Rs4680 was not a moderator. CONCLUSION: Findings suggest discrimination and rs4680 genotype are associated with depressive symptoms in Latinx adults, which may increase CVD risk. Further research is needed to better understand biological mechanisms of these relationships.

Unpacking the behavioural components and delivery features of early childhood obesity prevention interventions in the TOPCHILD Collaboration: a systematic review and intervention coding protocol.

INTRODUCTION: Little is known about how early (eg, commencing antenatally or in the first 12 months after birth) obesity prevention interventions seek to change behaviour and which components are or are not effective. This study aims to (1) characterise early obesity prevention interventions in terms of target behaviours, delivery features and behaviour change techniques (BCTs), (2) explore similarities and differences in BCTs used to target behaviours and (3) explore effectiveness of intervention components in preventing childhood obesity. METHODS AND ANALYSIS: Annual comprehensive systematic searches will be performed in Epub Ahead of Print/MEDLINE, Embase, Cochrane (CENTRAL), CINAHL, PsycINFO, as well as clinical trial registries. Eligible randomised controlled trials of behavioural interventions to prevent childhood obesity commencing antenatally or in the first year after birth will be invited to join the Transforming Obesity in CHILDren Collaboration. Standard ontologies will be used to code target behaviours, delivery features and BCTs in both published and unpublished intervention materials provided by trialists. Narrative syntheses will be performed to summarise intervention components and compare applied BCTs by types of target behaviours. Exploratory analyses will be undertaken to assess effectiveness of intervention components. ETHICS AND DISSEMINATION: The study has been approved by The University of Sydney Human Research Ethics Committee (project no. 2020/273) and Flinders University Social and Behavioural Research Ethics Committee (project no. HREC CIA2133-1). The study's findings will be disseminated through peer-reviewed publications, conference presentations and targeted communication with key stakeholders. PROSPERO REGISTRATION NUMBER: CRD42020177408.

Transforming Obesity Prevention for CHILDren (TOPCHILD) Collaboration: protocol for a systematic review with individual participant data meta-analysis of behavioural interventions for the prevention of early childhood obesity.

INTRODUCTION: Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of individual and trial-level subgroups. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and to explore whether there are differential effects among key subgroups. METHODS AND ANALYSIS: Systematic searches of Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycInfo and trial registries for all ongoing and completed randomised controlled trials evaluating behavioural interventions for the prevention of early childhood obesity have been completed up to March 2021 and will be updated annually to include additional trials. Eligible trialists will be asked to share their IPD; if unavailable, aggregate data will be used where possible. An IPD meta-analysis and a nested prospective meta-analysis will be performed using methodologies recommended by the Cochrane Collaboration. The primary outcome will be body mass index z-score at age 24±6 months using WHO Growth Standards, and effect differences will be explored among prespecified individual and trial-level subgroups. Secondary outcomes include other child weight-related measures, infant feeding, dietary intake, physical activity, sedentary behaviours, sleep, parenting measures and adverse events. ETHICS AND DISSEMINATION: Approved by The University of Sydney Human Research Ethics Committee (2020/273) and Flinders University Social and Behavioural Research Ethics Committee (HREC CIA2133-1). Results will be relevant to clinicians, child health services, researchers, policy-makers and families, and will be disseminated via publications, presentations and media releases.

Blood's Concentration of Lead and Arsenic Associated with Anemia in Peruvian Children.

This exploratory, descriptive cohort study (N = 60) determined lead (Pb) and arsenic (As) blood concentrations in Peruvian children and their association with hematological parameters of iron-deficient anemia (IDA) and anthropometric measurement. The mean age of children was 10.8 months (SD = 4.7) and ranged from 3 to 24 months old. Anemia (Hb levels below 10.5 g/dL) was found in 20% of this cohort. Additionally, microcytosis (MCV < 70 fL) was present in 54%, and hypochromia (MCH < 23 pg) in 42% of the group of children. Chi-square analysis showed that 88% of the children with anemia also had microcytosis and hypochromia (p < 0.001). Pb and As were detected in 100% of the infants' blood samples, and the concentrations were significantly higher in older infants than in younger ones. Pb and As were not associated with the sex, anthropomorphic parameters, or infant hemogram changes. Infants who received iron supplementation were 87% less likely to have low Hb compared with those who did not (OR = 0.13, 95% CI = 0.02-0.88, p=0.04). Herbal tea intake was significantly associated with microcytosis and hypochromia. Our finding uncovered that hematological parameters for anemia are modified in Peruvian children with high levels of microcytosis and hypochromia. Concentrations of Pb and As were above method detection limits in all Peruvian children, but these were not associated with IDA or anthropometric measurements. A large study, including other variables, would benefit from allowing a more complex model predicting anemia in Peruvian children.

Women's Perceptions of Hospital-Based Breastfeeding Care and the Association With Exclusive Breastfeeding.

OBJECTIVE: To examine the differences in women's perceptions of hospital-based breastfeeding care and the association of these perceptions with exclusive breastfeeding. DESIGN: Observational, mixed-methods study. SETTING/LOCAL PROBLEM: A 932-bed, Baby-Friendly Hospital Initiative-designated, university hospital with approximately 2,000 births per year, where 50% of women who wanted to breastfeed were supplementing with formula before hospital discharge. PARTICIPANTS: Thirty-four women who gave birth to a term, singleton newborn and had a desire to breastfeed exclusively. MEASUREMENTS: Women's perceptions were assessed using a modified version of the Questionnaire for the Breastfeeding Mother. RESULTS: Women's perceptions of breastfeeding care were positively associated with exclusive breastfeeding (p = .049). In addition, the influence of how a woman's own mother fed her as an infant was shown, because women who themselves were breastfed as infants were more likely to exclusively breastfeed their own newborns. Content analysis showed that women appreciated the care received in the hospital from lactation consultants and access to a hospital-administered breastfeeding clinic after discharge. CONCLUSION: Creating a hospital environment supportive of breastfeeding could yield positive breastfeeding outcomes for women and newborns.

Evaluación del disbalance autonómico en el paciente con serología positiva para enfermedad de Chagas: Score de diagnóstico y tratamiento

La enfermedad de Chagas es una enfermedad parasitaria (Trypanosoma cruzi), endémica en 21 países de América y que las migraciones la han dispersado en distintos continentes. Una de las manifestaciones más precoces de esta enfermedad son las alteraciones disautonómicas o disfunción autonómica. La severidad de este inadecuado funcionamiento del sistema nervioso autónomo resulta mensurable, de modo que la evolución y/o progresión de la enfermedad puede constatarse mediante la alteración de estudios clínicos y detección de anticuerpos antimuscarínicos. Estos anticuerpos están presentes en un 30% de los infectados y aparecen muy precozmente una vez instalada la parasitosis; además otros estudios, como la dispersión del QT (>65 mseg) y la variabilidad de la frecuencia cardíaca (<100 mseg) presentan valores anormales. La utilización de nuevos paradigmas de atención, diagnóstico y tratamientos adecuados son imprescindibles para prevenir el desarrollo de esta cardiopatía.

Chagas disease is a parasitic disease (Trypanosoma cruzi), endemic in 21 countries of America and that migrations have dispersed it in different continents. One of the earliest manifestations of this disease is dysautonomic alterations or autonomic dysfunction. The severity of this inadequate functioning of the autonomic nervous system is measurable, so that the evolution and/or progression of the disease can be verified by altering clinical studies and detecting antimuscarinic antibodies. These antibodies are present in 30% of those infected and appear very early once the parasitosis is installed; In addition, other studies, such as QT dispersion (> 65 ms) and heart rate variability (<100 ms) show abnormal values. The use of new paradigms of care, diagnosis and appropriate treatments are essential to prevent the development of this heart disease.

SETTING AND PARTICIPANTS: A total of 630 patients aged 70 and older with Coronavirus Disease 2019 COVID-19 living in 55 NHs. METHODS: A logistic regression was performed to analyze the factors associated with mortality. In addition, Kaplan-Meier curves were applied according to mortality and its associated factors using the log-rank Mantel-Cox test. RESULTS: The diagnosis of COVID-19 was mainly made by clinical compatibility (N = 430). Median age was 87 years, 64.6% were women and 45.9% were transferred to be cared for at the hospital. A total of 282 patients died (44.7%) within the 30 days of first attention by the team. A severe form of COVID-19 occurred in 473 patients, and the most frequent symptoms were dyspnea (n = 332) and altered level of consciousness (n = 301). According to multiple logistic regression, male sex (P = .019), the Clinical Frailty Score (CFS) ≥6 (P = .004), dementia (P = .012), dyspnea (P < .001), and having a severe form of COVID-19 (P = .001), were associated with mortality, whereas age and care setting were not. CONCLUSIONS AND IMPLICATIONS: Mortality of the residents living in NHs with COVID-19 was almost 45%. The altered level of consciousness as an atypical presentation of COVID-19 should be considered in this population. A severe form of the disease, present in more than three-quarters of patients, was associated with mortality, apart from the male sex, CFS ≥6, dementia, and dyspnea, whereas age and care setting were not. These findings may also help to recognize patients in which the Advance Care Planning process is especially urgent to assist in the decisions about their care.

Degree of Agreement Between Infant Serum and Salivary Concentration of Leptin and Adiponectin and Its Association With Infants' Feeding.

BACKGROUND: Leptin and adiponectin, two adipokines involved in glucose and lipid metabolism, have been linked to regulation of growth in early infancy, energy balance, and metabolic disorders in childhood. The aim of this study was to determine if concentrations of leptin and adiponectin could be measured reliably in infants' saliva, to evaluate the degree of agreement with infant serum levels, and to explore their association with infant feeding status. METHODS: A total of 34 infants were recruited after birth and followed for 20 weeks. After log-transformation of the values, a Bland-Altman graphical approach was used to summarize the direction of the difference between the serum and saliva values. Repeated measures mixed modeling was used to evaluate differences over time in these outcomes by feeding status. RESULTS: Mean concentration of salivary leptin and adiponectin in infants was 3.7 (SD = .8) ng/mL and 2.9 (SD = 0.7) ng/mL, respectively. The degree of agreement between serum and saliva for log-transformed leptin and adiponectin values were relatively robust, albeit with a non-zero bias between the two methods, given that serum values were greater than corresponding saliva values for both adipokines in all infants. Each of the four repeated measures mixed models (one for each adipokine measure) had a significant main effect; however, the interaction between time and feeding status was not significant in any of the models. CONCLUSION: This study demonstrated that leptin and adiponectin can be measured in infant saliva, but in some cases leptin concentrations may be more difficult to detect.
