Archaeobotanical evidence supports indigenous cucurbit long-term use in the Mesoamerican Neotropics.

The squash family (Cucurbitaceae) contains some of the most important crops cultivated worldwide and has played an important ecological, economic, and cultural role for millennia. In the American tropics, squashes were among the first cultivated crop species, but little is known about how their domestication unfolded. Here, we employ direct radiocarbon dating and morphological analyses of desiccated cucurbit seeds, rinds, and stems from El Gigante Rockshelter in Honduras to reconstruct human practices of selection and cultivation of Lagenaria siceraria, Cucurbita pepo, and Cucurbita moschata. Direct radiocarbon dating indicates that humans started using Lagenaria and wild Cucurbita starting ~ 10,950 calendar years before present (cal B.P.), primarily as watertight vessels and possibly as cooking and drinking containers. A rind directly dated to 11,150-10,765 cal B.P. represents the oldest known bottle gourd in the Americas. Domesticated C. moschata subsequently appeared ~ 4035 cal B.P., followed by domesticated C. pepo ~ 2190 cal B.P. associated with increasing evidence for their use as food crops. Multivariate statistical analysis of seed size and shape show that the archaeological C. pepo assemblage exhibits significant variability, representing at least three varieties: one similar to present-day zucchini, another like present-day vegetable marrow, and a native cultivar without modern analogs. Our archaeobotanical data supports the hypothesis that Indigenous cucurbit use started in the Early Holocene, and that agricultural complexity during the Late Holocene involved selective breeding that encouraged crop diversification.

Distinct roles of the left and right prelimbic cortices in the modulation of ethanol consumption in male mice under acute and chronic social defeat stress.

RATIONALE: Chronic stress exposure disrupts the medial prefrontal cortex's (mPFC) ability to regulate impulses, leading to the loss of control over alcohol drinking in rodents, emphasizing the critical role of this forebrain area in regulating alcohol consumption. Moreover, chronic stress exposure causes lateralization of mPFC functions with volumetric and functional changes, resulting in hyperactivity in the right hemisphere and functional decrease in the left. OBJECTIVES: This study investigated the inhibitory role of the left prelimbic cortex (LPrL) on ethanol consumption induced by chronic social defeat stress (SDS) in male mice and to examine if inactivation of the LPrL causes disinhibition of the right mPFC, leading to an increase in ethanol consumption. We also investigated the role of lateralization and neurochemical alterations in the mPFC related to ethanol consumption induced by chronic SDS. To this end, we examined the activation patterns of ΔFosB, VGLUT2, and GAD67 in the left and right mPFC. RESULTS: Temporarily blocking the LPrL or right PrL (RPrL) cortices during acute SDS did not affect male mice's voluntary ethanol consumption in male mice. When each cortex was blocked in mice previously exposed to chronic SDS, ethanol consumption also remained unaffected. However, male mice with LPrL lesions during chronic SDS showed an increase in voluntary ethanol consumption, which was associated with enhanced ΔFosB/VGLUT2-positive neurons within the RPrL cortex. CONCLUSIONS: The results suggest that the LPrL may play a role in inhibiting ethanol consumption induced by chronic SDS, while the RPrL may be involved in the disinhibition of ethanol consumption.

Phenotypic resistance not associated with knockdown mutations (kdr) in Anopheles albimanus exposed to deltamethrin in southern coastal Ecuador.

BACKGROUND: Decrease in malaria rates (e.g. incidence and cases) in Latin America maintains this region on track to achieve the goal of elimination. During the last 5 years, three countries have been certified as malaria free. However, the region fails to achieve the goal of 40% reduction on malaria rates and an increase of cases has been reported in some countries, including Ecuador. This scenario has been associated with multiple causes, such as decrease of funding to continue anti-malarial programmes and the development of insecticide resistance of the main malaria vectors. In Ecuador, official reports indicated phenotypic resistance in Aedes aegypti and Anopheles albimanus to deltamethrin and malathion, particularly in the coastal areas of Ecuador, however, information about the mechanisms of resistance have not been yet elucidated. This study aims to evaluate phenotypic response to deltamethrin and its relationship with kdr mutations in An. albimanus from two localities with different agricultural activities in southern coastal Ecuador. METHODS: The CDC bottle assay was carried out to evaluate the phenotypic status of the mosquito's population. Sequencing the voltage gated sodium channel gene (VGSC) sought knockdown mutations (kdr) in codons 1010, 1013 and 1014 associated with resistance. RESULTS: Phenotypic resistance was found in Santa Rosa (63.3%) and suspected resistance in Huaquillas (82.1%); with females presenting a higher median of knockdown rate (83.7%) than males (45.6%). No statistical differences were found between the distributions of knockdown rate for the two localities (p = 0.6048) which indicates no influence of agricultural activity. Although phenotypic resistance was confirmed, genetic analysis demonstrate that this resistance was not related with the kdr mechanism of the VGSC gene because no mutations were found in codons 1010 and 1013, while in codon 1014, 90.6% showed the susceptible sequence (TTG) and 7.3% ambiguous nucleotides (TKK and TYG). CONCLUSIONS: These results highlighted the importance of continuous monitoring of resistance in malaria vectors in Ecuador, particularly in areas that have reported outbreaks during the last years. It is also important to elucidate the mechanism involved in the development of the resistance to PYs to propose alternative insecticides or strategies for vector control in areas where resistance is present.

Forensic significance of Roundup Full® II effect on the development of Dermestes maculatus (Coleoptera: Dermestidae) and Lucilia sericata (Diptera: Calliphoridae).

The most widely used herbicides in the world are glyphosate formulations. These have been used in self-poisoning and accidental poisoning. Dermestes maculatus (Coleoptera: Dermestidae) and Lucilia sericata (Diptera: Calliphoridae) are associated with decomposing human and animal remains. The aim of the study was to evaluate Roundup Full® II effects on saprophagous insects´ development. For this, green bottle flies and hide beetles were exposed to different doses of the herbicide. The duration of life cycles was recorded by observations made every 8 and 24 h. To register possible variations in size, external morphology, and female proportion, specimens of all developmental stages were collected. The duration of developmental stages in L. sericata did not change due to the herbicide, but this reduced all size parameters of puparium with pupae inside, the weight of L1, and of adults. The larval stage and total duration in D. maculatus were decreased by the highest dose, while size parameters of hide beetles remained unchanged at all development stages. In both flies and beetles, there was no evidence of abnormal external morphology and the female proportion did not change in response to the herbicide. Finally, this study exhibited an impact on L. sericata and D. maculatus, so the possibility that the herbicide may affect other forensically important species should be considered, but more work is needed. Taxonomic determination could be done as usual; however, caution should be exercised when estimating the postmortem interval. This study represents the first to analyze a glyphosate-based herbicide associated with Forensic Entomology.

Juvenile variable stress modulates, in female but not in male Wistar rats, ethanol intake in adulthood.

Early stress can increase vulnerability to psychopathological disorders, including substance use disorders. The effects of stress in the juvenile period of the rat, that extends between weaning and the onset of adolescence (equivalent to late human childhood), have received little attention. This study assessed short and long-term behavioral effects of juvenile stress, with a focus on effects on ethanol intake. Male and female Wistar rats were exposed to variable stress (restraint, elevated platform, forced swimming, and social instability) or to restraint stress only, between postnatal days 26 to 29 (PDs 26-29). During adolescence, patterns of anxiety (PD 31) and depression (PD 33), ethanol intake (PDs 36-45) and behavioral sensitivity to the effects of acute stress (PD 47) were evaluated. In adulthood, alcohol ingestion was assessed through two-bottle ethanol intake tests (PDs 75-85). An additional experiment measured blood ethanol levels after a limited access intake session in adolescence. Exposure to juvenile variable stress exerted very mild effects in adolescence, but reduced ethanol ingestion in adulthood, in females only. Ethanol intake during the limited access session was significantly correlated to blood alcohol levels. The results indicate that a schedule of juvenile variable stress that did not significantly alter anxiety-related behaviors induced, nonetheless, sexually dimorphic effects on ethanol intake in adulthood. Early stress exposure that reduced alcohol intake in Wistar rats has been associated with changes on brain opioid and dopamine receptors. These results highlight the impact of early stress exposure on adult female ethanol consumption and its possible underlying neurobiological changes, involving opioid and dopamine receptors.

Relationship Between Feeding to Sleep During Infancy and Subsequent Childhood Disease Burden.

OBJECTIVE: To investigate the association of feeding to sleep during infancy and subsequent childhood health burdens. STUDY DESIGN: Information was collected from the parents of children who participated in the national health screening survey when the child was 9-12 months old. The exposure group included participants who were fed to sleep. The primary outcome was all-cause hospital admission (inpatient care, intensive care unit [ICU] admission, or general anesthesia) after age 24 months. Secondary outcomes were subsequent childhood diseases (ie, adenoidectomy and/or tonsillectomy, nasal polyps, allergic rhinitis, acute otitis media, asthma, pneumonia, and aspiration pneumonia), and growth status, as measured by weight-to-age and height-to-age z-scores. RESULTS: The study cohort consisted of 224 075 children who participated in the health screening program, 29 392 of whom (13.1%; 51% males) were fed to sleep. Exposure was associated with an increased risk of all-cause hospitalization after age 24 months (hazard ratio [HR], 1.05; 95% CI, 1.03-1.07), but not with admission to an ICU or receipt of general anesthesia. This also was related to adenoidectomy and/or tonsillectomy (HR, 1.08; 95% CI, 1.01-1.15), dental caries (HR, 1.32; 95% CI, 1.23-1.40), asthma (HR, 1.14; 95% CI, 1.14-1.24), pneumonia (HR, 1.10; 95% CI, 1.07-1.13), overweight (HR, 1.06; 95% CI, 1.03-1.09), and obesity (HR, 1.11; 95% CI, 1.06-1.16). CONCLUSIONS: Several adverse health outcomes are related to feeding to sleep during early childhood.

Feeding development of children with microcephaly: a descriptive study / Desenvolvimento alimentar de crianças com microcefalia: estudo descritivo

ABSTRACT Purpose: to describe feeding characteristics of children with microcephaly, encompassing the feeding route, food consistencies, and utensils used to feed them. Methods: a descriptive study approved by the Research Ethics Committee, including 34 caregivers of children diagnosed with microcephaly. They answered a structured interview on the children's feeding route, breastfeeding, utensils used to feed them, and the food consistencies, besides sociodemographic and overall development data. Descriptive statistical analyses were performed, presenting absolute and percentage frequencies and measures of central tendency and dispersion. Results: the 34 caregivers in the sample were responsible for 34 children born between 2015 and 2018, diagnosed with microcephaly, due to various causes. Of these, 33 (97.02%) were on oral feeding in their first year of life - 26 (76.44%) on breastfeeding, nine of which (26.46%) exclusively so until 6 months old. The children were served food in baby bottles, cups, spoons, and syringes. Pureed food was the consistency most accepted by the children. Conclusions: there was a low prevalence of exclusive breastfeeding until they were 6 months old, delayed progress of consistencies, use of utensils inadequate to their age, and necessary adaptations to feed children, orally.

Dessas, 33 (97,02%) alimentaram-se por via oral durante o primeiro ano de vida, sendo que 26 (76,44%) foram amamentadas, nove delas (26,46%) de forma exclusiva até o sexto mês. Para oferta do alimento foram utilizados mamadeira, copo, colher e seringa. A consistência alimentar mais aceita pelas crianças foi a pastosa. Conclusões: observa-se baixa prevalência de aleitamento materno exclusivo até o sexto mês, atraso na progressão de consistências, uso de utensílios inadequados para a idade e necessidade de adaptações para as crianças que se mantiveram em alimentação por via oral.

Association between Pacifier Use, Bottle-Feeding, and Pre-Postnatal Variables: A Cohort Study

ABSTRACT Objective: To determine the prevalence and analyze the variables associated with the use of pacifiers and/or bottles by infants up to 6 months of age. Material and Methods: Data on sociodemographic characteristics, intention to offer pacifier and bottle-feeding, pregnancy and breastfeeding (BF) variables were collected at baseline by interviews and a self-administered questionnaire among pregnant women in the 3rd trimester. After delivery, mother-baby binomials were followed by phone calls at the 1st, 3rd, and 6th months of the baby's life (n=467) to gather information on the type of delivery, baby's gender, BF in the first hour of the newborn's life, baby's weight, mother's return to work, and oral habits. Association analyses were performed using logistic regression models with a 5% significance level with the pacifier/bottle-feeding use as the outcome. Results: Most mothers (52.5%) reported their babies used bottle-feeding, 48.2% used pacifiers and 33.4% used both of them throughout the 6 months. Intention to offer pacifier and bottle-feeding was reported by 45.0% and 54.8% of the mothers at the 3rd trimester of the pregnancy, respectively. Not living in one's own residence (OR=1.53; 95%CI: 1.05-2.24) and having the prenatal intention of offering a pacifier (OR=2.50; 95%CI: 1.63-3.83) to the baby were significantly associated with pacifier use. Variables significantly associated with bottle-feeding were mother's return to work (OR=2.48; 95%CI: 1.54-3.97), baby's lower birth weight (OR=1.58; IC95%: 1.07-2.33), and prenatal intention to offer bottle-feeding (OR=2.51; 95%CI 1.56-4.04). Conclusion: About half of the babies used pacifiers or were bottle-fed, which were associated with the mother's prenatal intention to offer them to their babies and socioeconomic factors.

Factors associated with infant feeding styles in the Federal District, Brazil.

Responsive feeding is currently the recommended feeding style, in which the key principle is reciprocity between the child and the caregiver. The lack of reciprocity characterizes non-responsive feeding styles, which are associated with unhealthy eating behaviors, losses in the regulation of hunger and satiety, and childhood obesity. To assess factors associated with feeding styles between infants aged 6-12 months old, a cross-sectional study with 474 pairs of mothers and infants from 6 to 12 months old was conducted in Public Health Units in the Federal District, Brazil. The questionnaire applied to mothers evaluated four feeding styles from nine subconstructs (Infant Feeding Style Questionnaire), breastfeeding, bottle use, maternal depression and anxiety, household food insecurity (HFI), and prematurity. Multiple linear regression analysis was performed using the automated backward method. Bottle use was positively associated with feeding styles Laissez-faire (Attention) (ß:0.56), Pressuring (Cereal) (ß:0.58) and Restrictive (Quantity) (ß:0.26). Breastfeeding was negatively associated with Laissez-faire (Attention) (ß:-0.29) and Pressuring (Cereal) (ß:-0.50). Higher maternal education was negatively associated with Pressuring (Cereal) (ß:-0.34) and Pressuring (Soothing) (ß:-0.36). HFI is positively associated with Restrictive (Quantity) (ß:0.25), and Prematurity is negatively associated with Laissez-faire (Attention) (ß:-0.33). An important positive association was found between non-responsive styles and both bottle use and HFI, while breastfeeding and higher maternal education exhibited a negative association. Therefore, feeding styles and their associated factors should be considered in the design of interventions that promote a healthy diet for infants.

Development of eight wireless automated cages system with two lick-o-meters each for rodents.

Drinking behavior has been used in basic research to study metabolism, motivation, decision-making and different aspects of health problems, such as anhedonia and alcohol use disorders. In the majority of studies, liquid intake is measured by weighing the bottles before and after the experiment. This method does not tell much about the drinking microstructure, e.g., licking bouts and periods of preference for each liquid, which could be valuable to understand drinking behavior. To improve the data acquisition of drinking microstructure, companies have developed lick-o-meters devices that acquire timestamps when animals approach or drink from a specific sipper. Nevertheless, commercially available devices have elevated costs. Here, we present a low-cost alternative for a lick-o-meter system that allows wireless data acquisition of licking from eight cages with two sippers each. We run a three-phase validation protocol to ensure 1) proper choice of the sensor to detect licks; 2) adaptation of the device to a wireless transmission and realistic in silico tests; and 3) in vivo tests to correlate the amount of licks measured by the prototype and the bottle weight. The capacitive sensor presented appropriate recall and precision for our device. After adaptation to wireless transmission, the in silico validation demonstrated low reading and transmission errors for the device even when tested in extreme simultaneous licking conditions. Finally, a positive correlation between volume consumption and lick's count in the in vivo test was observed, showing that the prototype can be used for in vivo studies interested in rodent drinking microstructure.Significant StatementThis study presents an innovative and low-cost solution for drinking behavioral studies: a lick-o-meter system based on an open-source hardware platform with a user-friendly interface software, capable of simultaneously receiving data from eight automated cages with two drinking bottles each. The lick-o-meter brings an accessible device to acquire high-quality and detailed data. This device also has the possibility to be adaptable to new types of sensors or other neuroscience tools capable of measuring brain activity simultaneously to the behavior.

Variation in Root-Related Traits Is Associated With Water Uptake in Lagenaria siceraria Genotypes Under Water-Deficit Conditions.

In many agricultural areas, crop production has decreased due to a lack of water availability, which is having a negative impact on sustainability and putting food security at risk. In plants, the plasticity of the root system architecture (RSA) is considered to be a key trait driving the modification of the growth and structure of roots in response to water deficits. The purpose of this study was to examine the plasticity of the RSA traits (mean root diameter, MRD; root volume, RV; root length, RL; and root surface area, SA) associated with drought tolerance in eight Lagenaria siceraria (Mol. Standl) genotypes, representing three different geographical origins: South Africa (BG-58, BG-78, and GC), Asia (Philippines and South Korea), and Chile (Illapel, Chepica, and Osorno). The RSA changes were evaluated at four substrate depths (from 0 to 40 cm). Bottle gourd genotypes were grown in 20 L capacity pots under two contrasting levels of irrigation (well-watered and water-deficit conditions). The results showed that the water productivity (WP) had a significant effect on plasticity values, with the Chilean accessions having the highest values. Furthermore, Illapel and Chepica genotypes presented the highest WP, MRD, and RV values under water-deficit conditions, in which MRD and RV were significant in the deeper layers (20-30 and 30-40 cm). Biplot analysis showed that the Illapel and Chepica genotypes presented a high WP, MRD, and RV, which confirmed that these may be promising drought-tolerant genotypes. Consequently, increased root diameter and volume in bottle gourd may constitute a response to a water deficit. The RSA traits studied here can be used as selection criteria in bottle gourd breeding programs under water-deficit conditions.

A sustainable and green chlorophyll/TiO2:W composite supported on recycled plastic bottle caps for the complete removal of Rhodamine B contaminant from drinking water.

This investigation reports the photocatalytic performance of the tungsten doped titania (TiO2:W or TW) with and without coating of chlorophyll (Chl) for the removal of the RhB dye from the drinking water. These particles were also supported on recycled plastic bottle caps (Bcap) to form other photocatalytic composites (TW/Bcap and TW + Chl/Bcap). The SEM images demonstrated that the TW particles without Chl had irregular shapes and sizes of 0.8-12 µm. The TW particles coated by the Chl presented shapes of quasi-rounded grains and smaller particle sizes of 0.8-1.8 µm. The photocatalytyic experiments showed that the photocatalyst powders containing Chl removed completely the RhB dye from the water after 2h under UV-VIS light, while the photocatalyst without Chl removed a maximum of 95% of the RhB. Interestingly, the TW/Bcap and TW + Chl/Bcap composites removed 94-100% of the RhB after 2h. Those ones removed such dye by photocatalysis and by physical adsorption at the same time (as confirmed by the absorbance and FTIR measurements), therefore, the removal of RhB was still very high. Scavenger experiments were also achieved and found that the •OH radicals are the main oxidizing species generated by the photocatalysts with and without Chl. The •O2- radicals and holes (h+) were the secondary oxidizing species. The presence of the chlorophyll on the photocatalyst increased in general the light absorption and the photocurrent. Overall, our work demonstrated that making composites with recycled plastic bottle caps is a feasible alternative to remove dyes from contaminated drinking water with high efficiency and low cost.

Ecodesign approach for pharmaceutical packaging based on Life Cycle Assessment.

Packaging ecodesign can contribute to improve the environmental performance of pharmaceutical products. The main goal of this article is to present an ecodesign approach based on Life Cycle Assessment (LCA) for pharmaceutical packaging, assessing opportunities to improve the packaging environmental performance, and providing ecodesign recommendations to the pharmaceutical sector. The proposed ecodesign approach consists of five phases. I) The most representative packaging of medicines in the market (blister, bottle, and sachet), with different sizes, materials and weights, were investigated. II) Three ecodesign strategies were selected to analyze with LCA: i) weight and/or volume reduction, ii) alternative types of packaging, and iii) transportation with less environmental impact. III-IV) A cradle-to-gate life cycle model has been implemented, including transport to pharmacies. Alternative transportation modes (truck, train, airplane, and ship) and different packaging production locations have been considered. Thirteen environmental categories have been analyzed. V) Ecodesign recommendations for improving the environmental performance of pharmaceutical packaging are presented in two stages: i) specific recommendations based on LCA, illustrated in sheets with examples of ecodesign, quantifying the environmental impact reduction of an ecodesign solution compared to the original; and ii) generic recommendations for different packaging life cycle phases. Ecodesign recommendations highlight the use of smaller-size packaging, avoiding superfluous elements and empty spaces, which reduces material and production costs, and transportation impacts; the selection of modes of transportation with less environmental impact, considering the packaging production location; and the use of electric vehicles for pharmacy distribution. This ecodesign approach based on LCA allows quantifying environmental impacts robustly to support the incorporation of environmental information from the design, material selection, and packaging production to distribution till the final consumer. This article emphasizes the importance of developing specific packaging ecodesign based on LCA to improve environmental performance and provide more informed recommendations to stakeholders.

Does ankyloglossia interfere with breastfeeding in newborns? A cross-sectional study.

BACKGROUND AND AIM: Ankyloglossia is a congenital anomaly that can affect breastfeeding. The aim was to evaluate the prevalence of ankyloglossia in newborns and breastfeeding difficulties reported by mothers; assess possible factors that may interfere with breastfeeding. METHODS: A cross-sectional study was conducted with 391 pairs of mothers/newborns at a university hospital. A pediatric dentist examined the oral cavity of the newborns for the occurrence of ankyloglossia. We analyzed medical records and the mothers answered a self-administered questionnaire to assess birth variables, breastfeeding difficulties, and sociodemographic factors. We calculated prevalence ratios (PRs) of breastfeeding difficulties according to the independent variables. RESULTS: The mean age of the newborns was 2.5±2.9 days and 52% were male. The prevalence of ankyloglossia was 15% and 91.4% of mothers reported not having breastfeeding difficulties. Ankyloglossia was not associated with breastfeeding difficulties (PR: 0.5; 95% CI: 0.2-1.4). Mothers with a low income (PR: 0.5; 95% CI: 0.3-0.8), those who received instructions on breastfeeding (PR: 0.4; 95% CI: 0.2-0.9), and those who breastfed exclusively (PR: 0.3; 95% CI: 0.1-0.8) had fewer breastfeeding difficulties. CONCLUSION: Successful breastfeeding was more dependent on being born at full term, the family income, receiving guidance with regard to breastfeeding, and exclusive breastfeeding. Although ankyloglossia was not associated with breastfeeding, future prospective studies should evaluate the long-term factors that may interfere with breastfeeding. RELEVANCE FOR PATIENTS: This study brings a new perspective on the importance of assessing ankyloglossia and breastfeeding difficulties, reinforces the benefits of exclusive breastfeeding and the need for breastfeeding instructions, as well as the need to evaluate breastfeeding before making a decision regarding frenectomy.

Violência entre parceiros íntimos, oferta de leite materno, substitutos e uso de mamadeiras no primeiro ano de vida / Intimate partner violence, breastfeeding, breastmilk substitutes and baby bottle use in the first year of life

Resumo O objetivo deste artigo é investigar a relação da violência física entre parceiros íntimos (VFPI) e a oferta de leite materno (LM), os substitutos do leite materno (SLM) e o uso de mamadeiras entre crianças entre 12 e 15 meses. Estudo transversal com mães em unidades de saúde do município do Rio de Janeiro, realizado entre junho de 2005 e dezembro de 2009. A VFPI foi identificada pela versão brasileira da Conflict Tactics Scales 1- Form R e as práticas de alimentação foram identificadas por recordatório de 24 horas. As associações foram verificadas por regressão logística mediante estimativas de razão de chances (RC) e intervalos de confiança de 95%. O leite materno foi ofertado a 58,5% das crianças e os substitutos do leite materno a 88,5%, e 70,5% das crianças usavam mamadeira. A violência física foi observada em 26,7% dos casais. Em lares onde os casais se agridem fisicamente há uma maior chance de não ofertar leite materno, maior chance de ofertar substitutos do leite materno e de usar mamadeira comparado aos lares onde não existe violência física. Os resultados chamam atenção para a necessidade de se investigar as relações intrafamiliares em casos que são identificadas práticas inadequadas de aleitamento, e de capacitar os profissionais de saúde para apoiar as famílias em situações de conflito.

Abstract This article aims to investigate the relationship between intimate partner physical violence (IPPV) and breastfeeding (BF), use of breastmilk substitutes (BMS) and bottle-feeding among children aged 12 to 15 months. This is a cross-sectional study with mothers in primary care facilities of the city of Rio de Janeiro. IPPV was identified by the Brazilian version of the Conflict Tactics Scales 1-Form R and feeding practices were identified by a 24-hour Dietary Recall. Associations were verified by logistic regression with odds ratio (OR) estimates and 95% confidence intervals. BF was offered to 58.5% of the children and BMS to 88.5%. Also, 70.5% of the children used a baby bottle. Physical violence was observed in 26.7% of couples. Households where couples physically abuse each other are more likely to not breastfeed (OR=2.14, p-value=0.030), to use breastmilk substitutes (OR=5.15, p-value=0.03) and bottle-feed (OR=2.71; p-value=0.01), when compared to households without physical violence. The results highlight the need to investigate intrafamily relationships in cases where inadequate breastfeeding practices are identified, and to enable health professionals to support families in conflict situations.

Expectation of parental control and the maintenance of bottle-feeding in childhood

Abstract Objective: To investigate association between parental locus of control (belief of individuals about what or who has control of the events of their lives) and bottle feeding habits among children from 3 to 5 years of age. Methodology: Parental locus of control validated in Brazil, and semi-structured questionnaire to obtain sociodemographic, health, and oral habit behaviors was applied to mothers of 992 preschool children. Outcome variable "use of feeding bottle" was studied according to the time of its use (≤36 months and >36 months). Simple logistic regression models were adjusted and raw odds ratios were estimated for variables of distal blocks, which contemplated parental locus of control, socioeconomic characteristics of family, and maternal habits. In the intermediate block, the variables for conditions of the child's birth and place of health care attendance during the prenatal period and early childhood were included. In the proximal block, the time of breastfeeding and pacifier use were reported. Variables were analyzed from the distal to the proximal block, and the individual analyses that presented p ≤ 0.20 remained in each model; included in the subsequent block were the variables with p ≤ 0.10, because this was a study of prevention. Results: Longer time of feeding bottle use was associated with the internal parental locus of control, mothers older than 31 years of age, white race, premature children, who used pacifiers and are treated in the private health system. Conclusions: Children who maintained the habit of feeding bottle use for a longer time were those whose mother presented an internal locus of control.

Do breastfed children have a lower chance of developing mouth breathing? A systematic review and meta-analysis.

OBJECTIVE: Determine the association between breastfeeding and the development of mouth breathing in children. MATERIALS AND METHODS: Seven databases were searched for studies investigating the association between the type of feeding and the development of the breathing pattern in children. Descriptive analysis and meta-analysis were performed, with the calculation of the prevalence and likelihood (odds ratios (95% CI)) of mouth breathing according to the duration of breastfeeding. RESULTS: The overall prevalence of mouth breathing was 44% (95% CI: 38-49) (N total = 1182). Breastfeeding was a protection factor against the development of mouth breathing (OR = 0.62; 95% CI: 0.41-0.93). The likelihood of developing mouth breathing was 41% and 34% lower among children that were breastfed for more than 12 and more than 24 months, respectively. No association was found between exclusive breastfeeding for up to 6 months and the occurrence of mouth breathing (OR = 0.60; 95% CI: 0.31-1.18). CONCLUSIONS: Due to the scarcity of cohort studies that met the inclusion criteria and the low certainty of the evidence, no strong evidence-based conclusion can be drawn. However, breastfeeding should be encouraged due to its possible protective effect, evidenced by the substantial reduction in the prevalence of mouth breathing pattern when performed for up to 2 years. Exclusive breastfeeding was not associated with the development of the breathing pattern. CLINICAL RELEVANCE: The results reveal that breastfeeding can protect children from the development of mouth breathing. Thus, healthcare providers should offer support so that mothers feel prepared and encouraged to perform breastfeeding. TRIAL REGISTRATION: PROSPERO registry: CRD42017062172.

Fatores que impedem o aleitamento materno estendido em Unidades Básicas de Saúde de Guarulhos / Factors that prevent prolonged breastfeeding in Basic Health Units in Guarulhos

A amamentação prolongada promove diversos benefícios à saúde da criança, bem como para mãe, família e sociedade. Diante disso e da escassez de estudos sobre os aspectos envolvidos na prática do aleitamento materno após o sexto de mês de vida, o presente estudo teve como objetivo conhecer os fatores que dificultam a manutenção do aleitamento materno estendido (a partir do sexto mês até dois anos ou mais). Tratou-se de um estudo transversal, realizado em quatro unidades básicas de saúde, sorteadas, localizadas no município de Guarulhos. A amostra foi composta por mães usuárias e funcionárias das unidades básicas de saúde em questão com filhos de seis a vinte e quatro meses de idade. Para a coleta de dados foram utilizados dois questionários informativos com as variáveis do estudo. As análises de regressão simples e múltipla foram usadas para investigar a associações entre as variáveis. A utilização de mamadeira e de chupeta foram fatores importantes para a interrupção do aleitamento materno estendido. No entanto, na análise ajustada, tem-se que a idade materna predispõe a interrupção da amamentação estendida. De acordo com o modelo múltiplo de regressão logística, a utilização de chupeta aumenta em quase 20 vezes a chance de não manutenção do aleitamento materno estendido e crianças que utilizam mamadeira têm esta chance aumentada em seis vezes. Conclui-se que o avançar da idade da criança, a mamadeira e a chupeta foram determinantes para a não manutenção do aleitamento materno estendido. O retorno ao trabalho e o armazenamento do leite materno foram apontados como as principais dificuldades para manutenção da amamentação.

Prolonged breastfeeding promotes several health benefits for the child, as well as for the mother, family, and society. Given this and the scarcity of studies on the aspects involved in the practice of breastfeeding after the sixth month of life, the present study aimed to discover the factors that make it difficult to maintain breastfeeding (from six monthx to two years or more). This was a cross-sectional study, carried out in four randomly selected basic health units located in the city of Guarulhos. The sample consisted of mothers and employees of the basic health units in question, with children aged between six and twenty-four months old. For data collection, two informative questionnaires with the study variables were used. Simple and multiple regression analyses were used to investigate associations between variables. The use of a bottle and a pacifier were important factors for the interruption of prolonged breastfeeding. However, in the adjusted analysis, maternal age predisposes them to interrupt of prolonged breastfeeding. According to the multiple logistic regression model, the use of a pacifier increases the chance of not maintaining prolonged breastfeeding by almost 20-fold, and children who use a bottle have this chance increased by six-fold. It is concluded that the child aging, bottle use, and pacifier use were decisive factors for not maintaining prolonged breastfeeding. Returning to work and storing breast milk were identified as the main difficulties in maintaining breastfeeding.

Desperdício de vacinas: uma revisão da literatura / Vaccine waste: a review of the literature / Residuos de vacunas: una revisión de la literatura

O presente artigo tem como objetivo sistematizar o que tem sido publicado sobre desperdício de vacinas multidoses e monodoses. Trata-se de uma revisão da literatura construída a partir da questão norteadora: O que a literatura tem publicado sobre o desperdício de vacinas? Os unitermos definidos foram: "vaccine", "waste", "vial wastage" e "multidose". Para a seleção dos artigos foram consultadas as bases de dados "PubMed", "Scielo", "Revista Vaccine", "Periódicos Capes", "Teses e Dissertações Capes". Optou-se em continuar a busca por mais estudos utilizando a técnica "schneeball". A amostra final foi constituída de 26 artigos e duas dissertações, sendo o texto mais antigo de 2002 e os mais recentes de 2017. A maioria teve sua publicação no idioma inglês e em periódicos internacionais. Concluímos que independentemente das causas de desperdício de vacinas, evidencia-se a importância do monitoramento desses desperdícios e de serem criadas estratégias para sua redução.
