In silico and in vitro tests can reveal promising anti-leishmania activity for natural products and their derivatives. The aim of this study was to investigate in silico the pharmacological activities of potential new chalcones and their leishmanicidal potential in vitro. The in silico study was carried out using the PASS, MolPredictX and Molegro Virtual Docker 6.0 programs. Antiparasitic activity was assessed in axenic promastigote and amastigote forms of Leishmania braziliensis. The cytotoxicity tests used the J77G8 cell line. The chalcones exhibited 50% cytotoxic concentration values (CC50) values > 50 μM. Chalcone 4 (named FERAI) presented the best activity with concentration for 50% of promastigotes and intracellular parasites forms (EC50) of 9.75 ± 1.7 and 10.13 ± 1.7 μM for promastigote and amastigote, respectively. Reactive oxygen species (ROS) testing presented increased ROS levels in the parasite at the FERAI concentrations of 10 μM (56.33%), 20 μM (61.76%) and 30 μM (67.13%). Molecular docking revealed interactions (binding energy) between FERAI and the enzymes UDP-glycosyl pyrophosphorylase (-56.8384), dihydroorotate-dehydrogenase (-132.276) and trypanothione-reductase (-151.281). Our results demonstrated the anti-leishmanial activity of chalcones, especially FERAI, with a noted raising of ROS levels in the parasite. Molecular docking revealed dihydroorotate dehydrogenase and trypanothione reductase as potential pharmacological targets for FERAI. antileishmania anti leishmania derivatives PASS 60 6 0 6. programs braziliensis JG J G J77G line CC50 CC (CC50 5 named EC50 EC (EC50 975 9 75 9.7 17 1 7 1. 1013 13 10.1 respectively (ROS 56.33%, 5633 56.33% , 56 33 (56.33%) 2 61.76% 6176 61 76 (61.76% 3 67.13%. 6713 67.13% . 67 (67.13%) binding energy UDPglycosyl UDP glycosyl 56.8384, 568384 56.8384 8384 (-56.8384) dihydroorotatedehydrogenase 132.276 132276 132 276 (-132.276 trypanothionereductase 151.281. 151281 151.281 151 281 (-151.281) antileishmanial leishmanial CC5 (CC5 EC5 (EC5 97 9. 101 10. 563 56.33 (56.33% 61.76 617 (61.76 671 67.13 (67.13% 56838 56.838 838 (-56.8384 132.27 13227 27 (-132.27 15128 151.28 15 28 (-151.281 (CC (EC 56.3 (56.33 61.7 (61.7 67.1 (67.13 5683 56.83 83 (-56.838 132.2 1322 (-132.2 1512 151.2 (-151.28 56.

This study highlights the synthesis of innovative polyurethane materials derived from Moringa oleifera oils extracted from two distinct sources. The oils were converted into their respective polyols through the in situ generated performic acid method. Diverse material characteristics were observed due to different agroclimatic and cultivation conditions for the sources. Extraction yields were 45.21% (source 1) and 40.32% (source 2), with acid values of 28.70 and 26.00 mg KOH per g of oil, respectively. Oleic acid constituted 79.87 and 67.11% of the oils composition, respectively. Nuclear magnetic resonance and Fourier transform infrared spectroscopy (FTIR) confirmed the hydroxylation of the oils. FTIR also identified the isocyanate structures in the synthesized polyurethane materials. Gel permeation chromatography analysis revealed a higher oligomer content in the polyol synthesized from the oil extracted from source 2. Thermogravimetric analysis demonstrated enhanced thermal stability post-oil conversion, highlighting decomposition stages for rigid and flexible segments. Differential scanning calorimetry indicated higher unsaturation in the oil extracted from source 1, resulting in an elevated crystallization temperature. Tensile testing showed increased elasticity as the [NCO]/[OH] ratio decreased in the material, emphasizing the influence of polyol and crosslinking agent concentrations on mechanical resistance of polyurethane materials. sources method 4521 45 21 45.21 1 4032 40 32 40.32 2, 2 , 2) 2870 28 70 28.7 2600 26 00 26.0 respectively 7987 79 87 79.8 6711 67 11 67.11 composition (FTIR postoil post conversion segments temperature NCO/OH NCOOH NCO / OH [NCO]/[OH 452 4 45.2 403 3 40.3 287 7 28. 260 0 26. 798 8 79. 671 6 67.1 45. 40. 67.

Methods used to determine pesticide residues in teas typically require several laborious steps for sample preparation before analysis. In this study, a simple method based on solid-liquid extraction with low-temperature partitioning (SLE/LTP) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) was optimized and validated for the determination of pesticide residues (pirimiphos-methyl, flutriafol, cyproconazole, and bifenthrin) in dehydrated green tea leaves. After low-temperature partitioning (LTP), the extract in acetonitrile was subjected to a clean-up step using primary secondary amine (PSA) and octadecylsilane (C18) as sorbents for chlorophyll removal. The optimized SLE/LTP-GC-MS method was validated, and it proved to be effective and selective for extracting pesticides from green tea samples, presenting limit of detection (LOD) and limit of quantification (LOQ) of 0.015 and 0.050 mg kg-1, respectively. Recovery ranged between 81-111%, coefficients of variation were less than 16% and coefficients of determination (R2) were greater than 0.990. The optimized and validated method was applied to green tea and 13 other tea varieties sampled in South and Southeast regions of Brazil. The pesticides under study were detected in some of those samples at values higher than the maximum residue limits (MRLs) allowed by the European Union. solidliquid solid liquid lowtemperature low temperature SLE/LTP SLELTP SLE LTP (SLE/LTP GCMS GC MS (GC-MS pirimiphosmethyl, pirimiphosmethyl pirimiphos methyl, methyl (pirimiphos-methyl flutriafol cyproconazole bifenthrin leaves LTP, , (LTP) cleanup clean up PSA (PSA C18 C (C18 removal SLE/LTPGCMS SLELTPGCMS LOD (LOD LOQ (LOQ 0015 0 015 0.01 0050 050 0.05 kg1, kg1 kg 1, 1 kg-1 respectively 81111%, 81111 81 111%, 111 81-111% 16 R2 R (R2 0990 990 0.990 Brazil MRLs (MRLs Union (LTP C1 (C1 LTPGCMS 001 01 0.0 005 05 kg- 81111% 8111 8 111% 11 81-111 (R 099 99 0.99 (C 00 0. 811 81-11 09 9 0.9 81-1 81-

ABSTRACT Beans are a vital component of the human diet, being able to supply a large part of the daily protein requirements of individuals, in addition to containing considerable amounts of iron, calcium, vitamins, carbohydrates, fiber, and lysine. Controlled germination is an accessible and effective technique that aims to improve the nutritional, functional, and sensory qualities of seeds intended for food consumption. This study aimed to characterize fresh and germinated beans of Phaseolus vulgaris (carioca, branco, preto, gordo varieties) and Vigna unguiculata (cowpea). The germination process was conducted in trays containing the sand substrate (350 g) in the environmental conditions of the laboratory. The fresh and germinated beans were evaluated for physicochemical variables in triplicate. The germination process increased moisture content, water activity, ash, pH, soluble alcohol acidity, proteins, ascorbic acid, phenols, tannins, flavonoids, anthocyanins, and carotenoids. On the other hand, there was a reduction in the content of lipids, starch, and total sugars in bean seeds. With the increase in bioactive compounds, it was found that the germination process is an excellent method for increasing the nutritional quality of beans. diet individuals iron calcium vitamins carbohydrates fiber lysine functional consumption carioca, carioca (carioca branco preto varieties cowpea. cowpea .

This study investigated the removal of contaminants in water by adsorption on thermoplastic starch (TPS) and kraft lignin (KL) composites. A study on the desorption of methylene blue (MB) and methyl orange (MO) dyes in water was also carried out, followed by the photodegradation of solutions containing dissolved dyes. Initially, the surface morphology of the TPS and TPS-KL films was analyzed by scanning electron microscopy, revealing advantageous characteristics for efficient adsorption of contaminants. Fourier transform infrared spectroscopy (FTIR) analysis made it possible to characterize the TPS and TPS-KL composites. The results demonstrate the reversibility of the process and confirm the lack of permanent chemical modification in the polymer matrix, indicating that the adsorption/desorption process is physical rather than chemical. This suggests that the adsorbent material can be reused without losing its fundamental structural properties. Furthermore, the study allows for verification of the chemical changes on the surfaces of the materials involved. Ultraviolet-visible spectroscopy (UV-Vis) results show that for MO, both substrates exhibited low adsorption capacity, with efficiency values close to 20%. In contrast, for MB, both composite materials displayed excellent dye adsorption rates, achieving efficiencies of 78% or higher. The photodegradation of adsorbed dyes revealed promising results.

RESUMO O aumento da fertilidade do solo no cultivo de hortaliças apresenta desafios, notadamente usando adubo verde de espécies espontâneas do bioma Caatinga, como a flor-de-seda (Calotropis procera [Ait.] R. Br.). Este estudo teve como objetivo avaliar e otimizar as eficiências física e econômica da rúcula em monocultivo, influenciadas por quantidades variáveis de biomassa de flor-de-seda. Um delineamento em blocos casualizados com sete tratamentos e cinco repetições foi utilizado. Os tratamentos consistiram de diferentes quantidades de biomassa de C. procera (20, 40, 60, 80 e 100 t ha-1 em base seca), juntamente com dois tratamentos adicionais em cada bloco: um controle (sem fertilização) e um com fertilização mineral. A cultivar de rúcula "Cultivada" foi adubada para máxima eficiência produtiva usando 63,31 t ha-1 de biomassa seca de C. procera, rendendo 8,45 t ha-1. A maior eficiência agroeconômica otimizada, refletindo uma renda líquida de R$ 111.007,64 por hectare, foi alcançada com 59,26 t ha-1 de biomassa seca de C. procera. A taxa de retorno foi de R$ 4,65 para cada real investido, com um índice de rentabilidade de 77,38%. Assim, utilizar biomassa de C. procera como adubo verde é uma tecnologia viável para produtores de rúcula em regiões semiáridas. desafios Caatinga flordeseda flor seda Calotropis Ait. Ait [Ait.

ABSTRACT Enhancing soil fertility in vegetable cultivation presents challenges, notably using green manure from spontaneous species in the Caatinga biome, such as roostertree (Calotropis procera [Ait.] R. Br.). This study aimed to evaluate and optimize the physical and economic efficiencies of monocropped arugula, as influenced by varying amounts of roostertree biomass. We employed a randomized block design with seven treatments and five replications. Treatments involved different quantities of C. procera biomass (20, 40, 60, 80, and 100 t ha-1 on a dry basis), along with two additional treatments in each block: a control (no fertilization) and one with mineral fertilization. The "Cultivada" arugula cultivar was fertilized for maximum productive efficiency using 63.31 t ha-1 of C. procera dry biomass, yielding 8.45 t ha-1. The highest optimized agroeconomic efficiency, reflecting a net income of BRL 111,007.64 per hectare, was achieved with 59.26 t ha-1 of C. procera dry biomass. The return rate was BRL 4.65 for every real investment, with a profitability index of 77.38%. Thus, using C. procera biomass as green manure is a viable technology for arugula producers in semi -arid regions. challenges biome Calotropis Ait. Ait [Ait. R Br.. Br Br. .

ABSTRACT BACKGROUND: Universal healthcare is a cornerstone of Brazil’s public health system. However, delayed diagnosis and treatment of chronic kidney disease (CKD) remain substantial issues. The scarcity of outpatient dialysis facilities contributes to extended hospital stays. This study aimed to examine how the time to dialysis initiation (TID) impacts mortality in patients with renal disease. OBJECTIVES: This study aimed to evaluate the correlation between variables affecting TID and mortality in hospitalized patients with renal disease. DESIGN AND SETTING: A cross-sectional study was conducted at Santa Marcelina Hospital in São Paulo. METHODS: This cross-sectional study was conducted in a tertiary hospital, involving adults with kidney disease who were referred to the emergency department between 2014 and 2017. Primary outcomes included TID and mortality rates. RESULTS: Among the 402 patients studied, the average age was 58.6 years, and 59.4% were men. The median hospital stay was 44.5 d. Notably, 28.1% of the patients began dialysis under emergency conditions. Diabetes and hypertension were the most prevalent causes of renal disease. A positive correlation was found between age and TID (P = 0.007). CONCLUSIONS: Primary care in Brazil often fails to effectively detect and manage CKD, leading to a higher incidence of emergency dialysis, particularly among older adults. This delay correlates with increased mortality rates. Older age is associated with delayed TID, prolonged hospital stays, and consequently higher mortality. These findings highlight the need for better primary care to effectively manage CKD and reduce hospitalization and mortality.

Abstract Objectives In the clinical routine of pediatricians, height is the most reliable indicator for assessing growth. However, there are situations where it is not possible to measure this parameter directly, making the estimation of height or length a useful alternative. The main goal of this study is to identify which segmental measure, including upper arm length (UAL), tibial length (TL), and knee-heel length (KHL), provides the stature estimate that most closely approximates directly measured height in the study participants. Methods Analytical cross-sectional study of the anthropometric and segmental measures of 248 participants, aged 0 to 14 years old, using Stevenson's and Kihara's equations to estimate indirectly measured height. Results The segmental measure that provided a measurement that deviated the least from the actual height was the KHL, followed by TL, both calculated using Stevenson's equations. Conclusion The use of segmental measures to infer a child's stature is valuable in clinical practice, particularly in bedridden and incapacitated patients. Based on the present findings, the KHL and TL segments yielded more accurate results than the UAL pediatricians growth However alternative UAL, , (UAL) (TL) kneeheel knee heel (KHL) participants crosssectional cross sectional 24 1 old Stevensons Stevenson s Kiharas Kihara childs child practice patients findings (UAL (TL (KHL 2

Abstract Objective Individuals with Down Syndrome (DS) exhibit a higher susceptibility to infections, suggesting potential immunological alterations within this population. Consequently, this study aims to assess the immune response profile in children with DS to identify potential immune dysfunctions associated with recurrent infections. Methods The authors conducted a retrospective analysis involving 49 DS patients, examining various epidemiological, clinical, cytogenetic, and laboratory variables. The studyʼs sample comprised patients aged 2-20 years, with a predominance of males. These patients were categorized into two groups based on the presence or absence of recurrent infections, as indicated by the Jeffrey Modell Foundation alert signs. Results Immunoglobulin (Ig) A, G, and M levels were deemed normal, although individuals with DS experiencing recurrent infections exhibited significantly lower IgA levels. Additionally, CD3, CD4, CD8, and CD19 lymphocyte counts were found to be within normal ranges, with no significant differences between the two groups. While overall data indicated normal seroconversion levels of pneumococcal polysaccharide antibodies, a notable impairment in seroconversion was observed among DS patients with recurrent infections compared to those without such infections. Conclusion The deficiency of anti-polysaccharide antibodies in individuals with DS may constitute an important immunological comorbidity. Therefore, it warrants further investigation, particularly among individuals with recurrent infections.

Abstract Objective Define and develop a set of entrustable professional activities (EPAs) to link clinical training and assessment of the hospital components of neonatal care in neonatology medical residency programs. Methods An exploratory study was conducted in two phases using a modified Delphi approach. In the first phase, a committee of five neonatology residency program coordinators drafted an initial set of EPAs based on the national matrix of competencies and on EPAs defined by international organizations. In the second phase, a group of neonatal care physicians and medical residents rated the indispensability and clarity of the EPAs and provided comments and suggestions. Results Seven EPAs were drafted by the coordinators´ committee (n = 5) and used in the content validation process with a group (n = 37) of neonatal care physicians and medical residents. In the first Delphi round, all EPAs reached a content validity index (CVI) above 0.8. The coordinators´ committee analyzed comments and suggestions and revised the EPAs. A second Delphi round with the revised EPAs was conducted to validate and all items maintained a CVI above 0.8 for indispensability and clarity. Conclusion Seven entrustable professional activities were developed to assess residents in the hospital components of neonatal care medicine. These EPAs might contribute to implementing competency-based neonatology medical residency programs grounded in core professional activities.

Abstract Objective To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. Method Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. Results There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. Conclusion Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns. neurodevelopment cognitive years 9 3 150 g excluded termequivalent term equivalent 12 2 BayleyIII III (Bayley-III 8 mildmoderate mild moderate 7 Pearsons Pearson s 005 0 05 0.05 0.18 018 -0.1 catchup catch up an 081 81 0.8 score. . score) 15 00 0.0 0.1 01 -0. 08 0. -0 -

Abstract Objectives To investigate the associations between caregivers’ burden, family quality of life (QoL), and siblings’ QoL in Brazilian families of children with cerebral palsy, and to analyze siblings’ QoL using as a parameter the QoL of typically developed Brazilian children. Methods It was a cross-sectional study. The 212 families, 212 caregivers and 131 siblings completed the Family Quality of Life Scale, Burden Interview, and KIDSCREEN-27 Child and Adolescent Version and Parents Version questionnaires at a neurorehabilitation center in southeast Brazil. Univariable and multivariable models were used. Results Family QoL significantly worsened as caregivers’ burden increased (95 % CI -0.66 to -0.38). Caregivers’ burden was significantly lower with increasing family QoL scores (95 % CI -0.52 to -0.30). Self-reported siblings’ QoL was significantly worse than that of their typically developed peers (95 % CI -7.6 to -3.6). Self-reported siblings’ QoL was significantly lower as siblings’ age (95 % CI -2.52 to -0.59) and caregivers’ burden (95 % CI -0.35 to -0.05) increased. Parent-reported siblings’ QoL was significantly lower with increasing caregivers’ burden (95 % CI -0.45 to -0.16) and higher as family QoL increased (95 % CI 0.09 to 0.37). Conclusions The cross-sectional nature of these data precludes any statement of causality. Family QoL worsened with higher caregivers’ burden levels. Lower caregivers’ burden scores were associated with a higher family QoL. Siblings’ QoL was impaired as compared to typically developed peers, worse among older siblings, and as caregivers’ burden increased and better with higher family QoL levels. Future multicenter studies may validate the generalizability of the present findings.

Abstract Objective To evaluate the association between inflammatory markers and abdominal fat assessed by ultrasound in prepubertal children with and without excess weight. Methods A cross-sectional study involving 241 prepubertal children, 156 with obesity, 37 with overweight, and 48 with normal weight, aged five to ten years, who were followed at a research unit on Childhood Obesity from a teaching hospital belonging to a public health system. The concentration of interleukin-6, tumor necrosis factor-α and C-reactive protein were assessed and regression analyses, considering outcome variables such as abdominal wall and intra-abdominal fat thickness measured by ultrasound, were performed. Results The findings highlighted an association between abdominal fat and inflammatory markers, even in children at this young age group. Subcutaneous fat showed a stronger association with inflammatory biomarkers compared to intra-abdominal fat when performing logistic regression, with a positive association between tumor necrosis factor-α and abdominal wall thickness equal to or greater than the 75th percentile in adjusted logistic regression (OR: 18.12; CI 95 %: 1.57: 209.55). Conclusions Abdominal wall fat, in contrast to what is often observed in adults, appears to have a greater impact on chronic inflammation related to excessive weight in very young children. crosssectional cross sectional 24 15 obesity 3 overweight 4 years system interleukin6, interleukin6 interleukin 6, 6 interleukin-6 factorα factor α Creactive C reactive analyses intraabdominal intra performed group th OR (OR 18.12 1812 18 12 9 % 1.57 157 1 57 209.55. 20955 209.55 . 209 55 209.55) adults 2 interleukin- 18.1 181 1.5 5 2095 209.5 20 18. 1. 209.

Resumo Introdução: É importante identificar fatores de risco para progressão da doença renal policística autossômica dominante (DRPAD). Entretanto, são escassos os estudos que avaliam esse assunto utilizando amostra brasileira. Portanto, o objetivo deste estudo foi identificar fatores de risco para desfechos renais e óbito em coorte brasileira de pacientes com DRPAD. Métodos: Os pacientes tiveram o primeiro atendimento médico entre janeiro/2002 e dezembro/2014, sendo acompanhados até dezembro/2019. Associações entre variáveis clínicas e laboratoriais com desfecho primário (redução sustentada de pelo menos 57% na TFGe em relação ao valor basal, necessidade de diálise ou transplante renal) e desfecho secundário (óbito por qualquer causa) foram analisadas pelo modelo de regressão múltipla de Cox. Entre 80 pacientes com DRPAD, foram excluídos aqueles menores de 18 anos, com TFG <30 mL/min/1,73 m2 e/ou aqueles com dados ausentes. Foram acompanhados 70 pacientes. Resultados: Fatores independentemente associados aos desfechos renais foram: comprimento renal total – Razão de Risco (HR) ajustada com intervalo de confiança de 95% (IC 95%): 1,137 (1,057–1,224), taxa de filtração glomerular – HR (IC 95%): 0,970 (0,949–0,992) e nível sérico de ácido úrico - HR (IC 95%): 1,643 (1,118–2,415). Diabetes mellitus – HR (IC 95%): 8,115 (1,985–33,180) e TFG – HR (IC 95%): 0,957 (0,919–0,997) foram associados ao desfecho secundário. Conclusões: Esses achados corroboram a hipótese de que comprimento renal total, TFG e nível sérico de ácido úrico podem ser importantes preditores prognósticos de DRPAD em uma coorte brasileira, o que pode ajudar a selecionar pacientes que necessitam de acompanhamento mais próximo.

Abstract Introduction: Identifying risk factors for autosomal dominant polycystic kidney disease (ADPKD) progression is important. However, studies that have evaluated this subject using a Brazilian sample is sparce. Therefore, the aim of this study was to identify risk factors for renal outcomes and death in a Brazilian cohort of ADPKD patients. Methods: Patients had the first medical appointment between January 2002 and December 2014, and were followed up until December 2019. Associations between clinical and laboratory variables with the primary outcome (sustained decrease of at least 57% in the eGFR from baseline, need for dialysis or renal transplantation) and the secondary outcome (death from any cause) were analyzed using a multiple Cox regression model. Among 80 ADPKD patients, those under 18 years, with glomerular filtration rate <30 mL/min/1.73 m2, and/or those with missing data were excluded. There were 70 patients followed. Results: The factors independently associated with the renal outcomes were total kidney length – adjusted Hazard Ratio (HR) with a 95% confidence interval (95% CI): 1.137 (1.057–1.224), glomerular filtration rate – HR (95% CI): 0.970 (0.949–0.992), and serum uric acid level – HR (95% CI): 1.643 (1.118–2.415). Diabetes mellitus - HR (95% CI): 8.115 (1.985–33.180) and glomerular filtration rate - HR (95% CI): 0.957 (0.919–0.997) were associated with the secondary outcome. Conclusions: These findings corroborate the hypothesis that total kidney length, glomerular filtration rate and serum uric acid level may be important prognostic predictors of ADPKD in a Brazilian cohort, which could help to select patients who require closer follow up.

Abstract Objective: To study the association between placental efficiency with anthropometry and nutritional phenotypes in full-term newborns from a birth cohort. Method: This was a secondary cross-sectional analysis of data obtained in a cohort study (Brazilian RibeirãoPreto and São Luís Birth Cohort Studies - BRISA), whose deliveries were performed between 2010 and 2011. Standardized questionnaires were applied to mothers, and placentas and newborns were evaluated shortly after delivery. Placental efficiency was assessed using the ratio between birth weight and placental weight (BW/PW ratio); values below the lower quartile (25th percentile for gestational age) were considered to have low placental efficiency. Newborn phenotypes were small and large for gestational age, stunted and wasted, evaluated using the INTERGROWTH-21 growth standard. To identify the confounding variables theoretical model was constructed using Directed Acyclic Graphs, and unadjusted and adjusted logistic regression were performed. Placental measurements were obtained blindly from pregnancy and delivery data. Results: 723 mother-placenta-child triads were studied. 3.2 % of newborns were small-for-gestational-age (SGA), 6.5 %large-for-gestational-age (LGA), 5.7 %had stunting, and 0.27 % wasting. A significantly higher risk was found between low placental efficiency and SGA (OR 2.82;95 % CI 1.05-7.57), stunting (OR 2.23; 95 % CI 1.07-4.65), and wasting (OR 8.22; 95 % CI 1.96-34.37). No relationship was found between LGA and placental efficiency. Conclusions: Low placental efficiency was associated with increased risk for small-for-gestational-age, stunting, and wasting. Placental morphometry can provide valuable information on intrauterine conditions and neonatal health, helping to identify newborns at higher risk of future comorbidities.
