Resumo Objetivo: Identificar quais tipos de reações de pele e ingredientes do brinquedo slime estão frequentemente envolvidos em relatos de intoxicação. Fontes de dados: Entre janeiro e julho de 2021, ocorreu a seleção dos artigos, utilizando-se as bases de dados: United States National Library of Medicine (PubMed), Scientific Electronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Foram utilizados os seguintes descritores: (dermatitis OR rash OR eczema OR inflammation) AND slime. Incluíram-se artigos disponíveis na íntegra, em português, inglês ou espanhol, publicados entre janeiro de 2000 e 31 julho de 2021, que relatassem casos de crianças e adolescentes que apresentaram reação cutânea após a manipulação do brinquedo slime. Foram excluídos artigos sem aderência ao tema e textos duplicados nas bases de dados. Síntese dos dados: Identificaram-se 65 publicações, sendo 16 utilizadas para a elaboração desta revisão. Isso resultou no total de 22 crianças (duas do sexo masculino, 20 do feminino), com idades entre quatro e 13 anos, que teriam sido intoxicadas por slime, a maioria dos casos ligado a preparações caseiras. Estudos relataram a ocorrência de dermatite de contato ou alérgica nas mãos, dedos, unhas, antebraços e bochechas. Os ingredientes mais alergênicos e/ou irritantes foram detergentes líquidos e sabão. Ademais, o patch test identificou reações positivas para metilisotiazolinona e metilcloroisotiazolinona, que são conservantes utilizados em produtos como cola, sabão, detergente, etc. Conclusões: Ainda que o brinquedo slime seja importante para o desenvolvimento motor e das relações parentais, receitas caseiras incluem vários ingredientes alergênicos e irritantes, que podem ser expostos a crianças vulneráveis e causar intoxicações. Sendo assim, as preparações do slime devem ser feitas com cautela e sob supervisão de adultos.

Abstract Objective: The aim of this study was to identify which types of skin reactions are associated with slime toys and which of their ingredients are most frequently involved in cases of poisoning. Data source: Between January and July 2021, articles were selected using PubMed, SciELO, and LILACS databases. The following descriptors were used: (dermatitis OR rash OR eczema OR inflammation) AND slime. Inclusion criteria were articles available in full, in either Portuguese, English, or Spanish, published between January 2000 and July 31, 2021, and articles reporting cases of contact dermatitis or eczema potentially or directly attributed to slime toys. Articles not meeting these criteria and duplicate texts in the databases were excluded. Data synthesis: In total, 65 publications were identified, of which 16 were included in this review. This resulted in a total of 22 children (2 males, 20 females), aged between 4 and 13 years, who were reportedly intoxicated by slime toys, most of these being linked to homemade preparations. Studies reported the occurrence of contact or allergic dermatitis on hands, fingers, nails, forearms, and cheeks. The most allergenic and/or irritant ingredients included liquid detergent and soap. Additionally, patch tests identified positive reactions to methylisothiazolinone and methylchloroisothiazolinone, the preservatives used by chemical industries on preparation of glue, soap, detergents, etc. Conclusions: Although slime toys might be important for improving motor development and parental relationships, homemade slime toy recipes include several allergenic and irritant ingredients which might be exposed to vulnerable children and cause intoxications. Therefore, homemade slime toys preparations should be used cautiously and under the supervision of adults.

ABSTRACT Salt stress stands out as one of the main limiting factors in agricultural production in arid and semi-arid regions, due to its osmotic and ionic effects on plants. In this context, the objective was to evaluate the physiological responses of sugar-apple seedlings irrigated with saline wastewater under different doses of NPK. The experiment was carried out in a greenhouse, in a randomized block design, in a 3 x 5 factorial scheme, with four replicates. Three irrigation waters were tested: local-supply water (control), reject brine and fish farming effluent, and five doses of NPK, referring to the proportions of 25, 50, 75, 100, and 125% of the N:P:K fertilizer recommendation of 100:300:150 mg dm-3. Seedlings were cultivated in 2-dm3 containers filled with sandy soil for 90 days after sowing. At the end of this period, gas exchange, chlorophyll fluorescence, and biomass accumulation were evaluated. The use of reject brine and fish farming effluent to irrigate sugar-apple seedlings reduced photosynthetic activity and biomass accumulation. The best physiological responses and biomass accumulation occur at NPK doses of 75% (75:225:112.5 mg dm-3 of N:P:K) for seedlings irrigated with local-supply water, 60% (60:180: 90 mg dm-3 of N:P:K) for seedlings irrigated with reject brine, and 40% (40:120:60 mg dm-3 of N:P:K) for seedlings irrigated with fish farming effluent.

RESUMO O estresse salino destaca-se como um dos principais fatores limitantes na produção agrícola nas regiões áridas e semiáridas, devido os efeitos osmótico e iônico sobre as plantas. Neste contexto, objetivou-se avaliar as respostas fisiológicas de mudas de pinheira irrigadas com águas residuárias salinas sob diferentes doses de NPK. Para isso, o experimento foi conduzido em casa de vegetação, em delineamento de blocos casualizado, em esquema fatorial 3 x 5, com quatro repetições. Foram testadas três águas de irrigação, sendo elas água de abastecimento local (controle), rejeito de dessalinizadores e efluente da piscicultura. E cinco doses de NPK, referentes as proporções de 25, 50, 75, 100 e 125% da recomendação de adubação de 100:300:150 mg dm-3 de N:P:K. As mudas foram conduzidas em recipientes com capacidade de 2 dm3 preenchido com solo de textura arenosa por 90 dias após a semeadura. No final desse período foram avaliadas as trocas gasosas, fluorescência da clorofila e o acúmulo de biomassa. O uso do rejeito salino e efluente da piscicultura na irrigação de mudas de pinha reduziu a atividade fotossintética e o acúmulo de biomassa. As melhores respostas fisiológicas e acúmulo de biomassa ocorrem nas doses de NPK de 75% (75:225:112,5 mg dm-3 de N:P:K) para mudas irrigadas com água de abastecimento, 60% (60:180:90 mg dm-3 de N:P:K) para irrigadas com rejeito salino e 40% (40:120:60 mg dm-3 de NPK), para irrigadas com efluente da piscicultura.

Abstract The aim of the present study was to evaluate semen cryopreservation with ACP-Lact® diluent, which consists of coconut water powder (ACP) added to goat milk powder. After thawing, the samples were evaluated for sperm kinetics, membrane evaluation and in vivo insemination. For cryopreservation, a pool was made with the ejaculate of six goats, diluted in four equal aliquots for the respective treatments: T1 (ACP-Lact®); T2 (ACP-Lact® 50%); T3 (ACP + 2.5% egg yolk) and T4 (Tris + 2.5% egg yolk). After dilution of the treatments, the samples were placed in 0.5 ml straws and chilled at a rate of -1.07°C/min. After reaching 4°C and stabilizing for one hour, the straws were placed in nitrogen vapour at -60°C for 15 minutes and then immersed in liquid nitrogen (-196ºC). The straws were thawed in a 37°C water bath and kinetic assessments were performed immediately using a computerized semen analysis program (CSA), viability (EN), membrane functionality (HOST), mitochondrial activity (DAB) and DNA integrity assessment of spermatozoa. For the in vivo experiment, ten goats were inseminated, divided into two groups of five goats each, G1 inseminated with ACP-Lact® and G2 with ACP, by fixed-time artificial insemination (FTAI). Regarding the kinetic parameters, the ACP-Lact® treatment showed higher progressive motility (PM) and sperm velocity than the other treatments (36.77%). In the VSL parameter the ACP-Lact diluent was superior to ACP and Tris. In viability the treatment with ACP-Lact® was superior to the treatment with Tris, 95% and 83% respectively. In FTAI two goats were born out of the 5 goats inseminated with ACP-Lact®. It was concluded that the use of ACP-Lact® for cryopreservation of caprine semen is efficient in maintaining seminal parameters during thawing in vitro and in vivo and proved to be a good alternative extender for the caprine species.

RESUMO O jambu é uma erva condimentar usada no preparo de pratos típicos e fitoterápicos na região Amazônica. São utilizados as inflorescências, as folhas e os caules da planta. Além disso, o jambu possui inúmeras aplicações nas indústrias de cosméticos e alimentícia devido à presença do composto bioativo espilantol. Objetivou-se com este estudo avaliar o desempenho produtivo e fisiológico de genótipos de jambu, das espécies Acmella oleracea e Acmella ciliata, cultivados em hidroponia. O delineamento utilizado foi inteiramente casualizado com oito tratamentos e quatro repetições. Os tratamentos foram constituídos por genótipos de jambu (UFR-1, UFR-2, UFR-3, UFR-4, UFR-5, UFR-6, UFR-7 e UFR-8) coletados em diferentes localidades do estado do Pará. Foram avaliados o início do pendoamento, comprimento da rama principal, diâmetro da rama principal, área foliar, massa fresca da parte aérea, massa fresca das inflorescências, massa fresca das raízes, massa fresca total, taxa de fotossíntese líquida, condutância estomática, concentração interna de CO2 e eficiência instantânea de carboxilação. Os genótipos apresentaram comportamentos distintos em relação às características de crescimento, produtivas e fisiológicas. Os genótipos UFR-1, UFR-2, UFR-3, UFR-4 e UFR-7 exibiram maior precocidade de floração. Em geral, genótipos da espécie A. oleracea apresentaram menor taxa de fotossíntese líquida se comparados aos da espécie A. ciliata. Os genótipos da A. oleracea apresentaram capacidade de acúmulo de massa fresca total, além de elevado potencial para produção de inflorescências. Destacaram-se os genótipos UFR-2 e UFR-4, pois apresentaram maiores produções de massa fresca da parte aérea e inflorescências, respectivamente. Portanto devem ser considerados em programas de melhoramento da cultura.

ABSTRACT Jambu is a condiment herb used in the preparation of typical and herbal dishes in the Amazon Region. The inflorescences, leaves, and stems of the plant are used. In addition, jambu has numerous applications in the cosmetics and food industries due to the presence of the bioactive compound spilanthol. The objective of this study was to evaluate the productive and physiological performance of jambu genotypes of Acmella oleracea, and Acmella ciliata species grown in hydroponics. The experiment used was a completely randomized design with eight treatments and four replicates. The treatments consisted of jambu genotypes (UFR-1, UFR-2, UFR-3, UFR-4, UFR-5, UFR-6, UFR-7 and UFR-8) collected in different locations in the state of Pará. We evaluated the beginning of flowering, length of the main branch, diameter of the main branch, leaf area, shoot fresh mass, inflorescence fresh mass, root fresh mass, total fresh mass, net photosynthetic rate, stomatal conductance, internal CO2 concentration, and instant carboxylation efficiency. The genotypes presented different behaviors about the productive and physiological growth characteristics. The genotypes UFR-1, UFR-2, UFR-3, UFR-4 and UFR-7 exhibited greater precocity of flowering. In general, genotypes of the species A. oleracea presented lower rate of net photosynthesis when compared to those of the species A. ciliata. The genotypes of A. oleracea showed total fresh mass accumulation capacity, in addition to a high potential for inflorescence production. The genotypes UFR-2 and UFR-4 stood out because they presented higher yields of shoots fresh mass and inflorescences, respectively. Therefore, these genotypes should be considered in crop improvement programs.

Abstract Effects were assessed of the dilutants TRIS and ACP - 101c® with the addition of different guinea fowl (Numida meleagris) egg yolk concentrations. Fifteen ejaculates were collected from five goats of the Anglo Nubian breed. The ejaculates were pooled and then divided into 12 groups, two control groups (GC1 TRIS, with 2.5% Gallus gallus domesticus hen egg yolk GOGD), (GC2 Control Group ACP - 101c®, with the addition of 2.5% Gallus gallus domesticus hen egg yolk GOGD) and ten experimental groups (EG), containing TRIS and ACP added with different concentrations of egg yolk from guinea hen (Numida meleagris) (TRIS 2,5% GONM; TRIS 5% GONM; TRIS 10% GONM; TRIS 15% GONM; TRIS 20% GONM; ACP® 2,5% GONM; ACP® 5% GONM; ACP® 10% GONM; ACP® 15% GONM; ACP® 20% GONM). Then cryopreservation was carried out and the samples stored in liquid nitrogen (-196 °C). After seven days, the samples were thawed and assessed for spermatic kinetics, immunofluorescence and sperm morphology. Analysis of GOMN by the CASA system showed that the various parameters were similar to those of GOGD (P>0.05). The membrane integrity, mitochondrial potential and the acrosome were not influenced by the treatment (P>0.05) nor by the dilutant used for cryopreservation (P>0.05). The spermatic morphology was also preserved by the different GOGD and GONM concentrations in the ACP® and TRIS dilutants, with no statistically significant differences (P<0.05). It was concluded that Numida meleagris egg yolk, as external membrane cryoproctant added to the dilutants ACP-101c® and TRIS, improved goat semen quality.

Abstract AISI D6 tool steel and AISI 304 stainless steel are among the most widely used material in the industry. However, this application field can still be expanded through the coatings deposition. In this regard, the objective of this work was to evaluate the impact of coatings application by cathodic cage technique using Hastelloy’s cathodic cage, on corrosion resistance of these steels. Two treatment temperatures were compared. The samples were characterized by Optical Microscopy, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-Ray Diffraction with the application of the Rietveld routine and corrosion test. The results showed the formation of multiphase layers that contributed to corrosion potentials reduction for treatments at 400 °C, being more effective when applied on AISI D6. It was observed that the corrosion resistance is influenced by the temperature, which was attributed to the precipitation of chromium nitride and iron oxide at 450 ºC.

Abstract: En | Text: En | PDF: En

Super duplex stainless steel (SDSS) combines corrosion resistance and mechanical properties, interesting to applications in the oil extraction industry. In this process, wear between the tools friction and rocky materials occurs with SDSS pipes. Due to the low tribological properties, plasma nitriding process is applied to provide a surface layer with excellent wear resistance and without significant losses in corrosion resistance. Here, conventional plasma nitriding (CPN) and cathodic cage plasma nitriding (CCPN) techniques were compared to modify SDSS surface. Before and after passing by these two nitriding processes, welded joints (WJ) were subjected to a microstructural and corrosion resistance evaluation. Aiming to characterize the final product obtained, it was used characterization techniques, such as scanning electron microscopy (SEM) and X-ray diffraction (XRD). Results show that using the CPN technique, at 400°C, was responsible for providing greater resistance to corrosion, when analyzing the result of potentiodynamic polarization — jpassivation = 2.60x10-5 A.cm-2 and Epite = 0.83 V than the CCPN technique when applied to the SSDS, and this was attributed to the formed diffusion layer, which is composed of the expanded austenite and ferrite phases.

ABSTRACT Toxoplasmosis is a zoonosis of reproductive nature that is transmitted to humans mainly by ingestion of undercooked meat or drinking oocyte-contaminated water. The slaughter of small ruminants in clandestine slaughterhouses and the presence of companion animals in these locations may be epidemiologically important for the dissemination of the disease. The objective of the present study was to determine toxoplasmosis prevalence by researching anti- Toxoplasma gondii antibodies in meat sheep herds from farms in Teresina microregion, Piauí, Brazil. A total of 450 blood samples were collected from sheep of both sexes, belonging to 28 herds from the 14 municipalities that comprise the microregion. The samples were analyzed by the enzyme-linked immunosorbent assay (ELISA), and the presence of anti-T. gondii antibodies was observed in 62% (279/450) of the animals in all the municipalities and on at least one farm in each municipality. The high occurrence of positive animals is an indication of reproductive problems in these herds, characterizing a problem for both sheep rearing and public health.

Resumo A leishmaniose visceral canina (LVC) é uma doença zoonótica de alta letalidade causada por Leishmania infantum nas Américas. No cão infectado, as formas amastigotas são escassas no sangue, principalmente na fase tardia da doença. Este estudo teve como objetivo relatar um caso raro de amastigotas de L. infantum encontradas em neutrófilos do sangue periférico de um cão naturalmente infectado e terminal da LVC, descrevendo também seu estado clínico antes e após o tratamento com miltefosina a 2%. O cão, que se apresentou como polissintomático e com sinais e sintomas clássicos da LVC foi submetido aos seguintes testes: teste rápido Dual Path Platform (DPP), ELISA e exame parasitológico de sangue periférico. Os parâmetros hematológicos e bioquímicos foram obtidos antes e após o tratamento. Todos os testes diagnósticos foram positivos para LVC. A identificação de formas amastigotas de L. infantum, dentro de neutrófilos do sangue periférico foi confirmada por microscopia, e a espécie foi confirmada por análise molecular. Ao final do tratamento, não foi detectada parasitemia periférica, observando-se melhora dos parâmetros clínicos e laboratoriais. Por fim, esse achado atípico pode ser usado como exemplo para levantar discussões sobre o real papel imunológico dos neutrófilos nas fases tardias da LVC e suas implicações clínicas/terapêuticas.

Abstract Canine visceral leishmaniasis (CVL) is a zoonotic disease of high lethality caused by Leishmania infantum in the Americas. In the infected dog, the amastigotes are scarce in blood, especially in the late phase of the disease. This study aimed to report a rare case of L. infantum amastigotes found in neutrophils from peripheral blood of a naturally infected dog in terminal phase of CVL, also describing its clinical status before and after treatment with miltefosine 2%. The dog, which presented as polysymptomatic and with classical signs and symptoms of CVL was submitted to the following tests: Dual Path Platform (DPP) rapid test, ELISA and parasitological examination of peripheral blood. Hematological and biochemical parameters were obtained before and after treatment. All diagnostic tests were positive for CVL. The identification of L. infantum amastigotes inside neutrophils from peripheral blood was confirmed through microscopy, and the species was confirmed by molecular analysis. At the end of the treatment, peripheral parasitemia was not detected, and improvements were observed in clinical and laboratorial parameters. Finally, this atypical finding can be used as example to raise discussions about the real immunological role of neutrophils in late phases of CVL and its clinical/therapeutic implications.

Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. Conclusão Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. Results The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. Conclusion The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

Abstract INTRODUCTION: Brazil has a high number of cases of American cutaneous leishmaniasis (ACL) in the north and northeast regions. Therefore, continuous surveillance of environmental and socioeconomic factors in endemic areas is needed to develop strategic control measures. This study aimed to describe the clinical and epidemiological profiles of patients with ACL. METHODS: All patients were from the states of Amazonas and Pernambuco, and examinations were carried out between 2015 and 2018. All patients had a clinical and epidemiological history compatible with ACL after positive diagnostic tests. Information obtained from medical records included gender, employment activity, level of education, age, and number and sites of lesions. RESULTS: A total of 213 patients were included, of whom 30.98% were female and 69.02% were male. The main employment activity was agriculture (27.56%). The most common level of education was elementary (62.42%). The average age was approximately 39 years. The majority of the patients presented only with one lesion (54.87%), and legs/feet were the most commonly affected area (48.25%), followed by the arms/hands (44.75%). CONCLUSIONS: These data demonstrated that irrespective of the patients’ places of origin, interventions need to be focused on men of economically productive age, in view of the high risk of exposure to the vector in this group. Education activities need to be directed to farmers about the importance of protection against ACL vectors during work. Such information must also be directed to employers as a way of implementing and maintaining appropriate working conditions and stepping up vector control.

Abstract Purpose To develop a 3D anatomical model for teaching canine epidural anesthesia (3DMEA) and to assess its efficacy for teaching and learning prior to the use of live animals. Methods The creation of 3DMEA was based on 3D optical scanning and 3D printing of canine bone pieces of the fifth to the seventh lumbar vertebrae, sacrum and pelvis. A total of 20 male dogs were scheduled for castration. 20 veterinary students watched a video showing epidural anesthesia in dogs before the clinical attempt and were assigned to control or 3DMEA groups. Students in the 3DMEA group trained in the model after the video. For the clinical trial, the epidural procedure was performed by students under the veterinary supervision. When observed the absence of response to nociceptive stimuli, the epidural was considered successful. Then, all students answered a questionnaire evaluating the main difficulty founded in the technique and its degree of difficulty. Results The 3DMEA group reported a lower degree of difficulty to perform the epidural anesthesia technique when compared with the control group (p=0.0037). The 3DMEA reproduced the anatomical structures, allowing the perception of the distance of needle in relation to the iliac prominences during epidural anesthesia. Its mobility allowed simulation of the animal in standing position and sternal recumbency. Conclusion The use of 3DMEA demonstrated greater efficacy in the execution of the technique, being effective in the teaching and learning process before the epidural anesthesia in live animals.

Resumo A Zona de Expansão de Aracaju apresenta problemas relacionados à falta de água em condições adequadas de quantidade e qualidade. O poder aquisitivo da comunidade nativa do local levou a população a construir poços rasos em suas residências para garantir o abastecimento de água, única alternativa para consumo doméstico, sem tratamento prévio. O objetivo deste trabalho foi avaliar a qualidade da água de poços e os cenários de risco à saúde, por meio das análises microbiológicas. As coletas foram realizadas no período de dezembro de 2015 a agosto de 2017, de acordo com a metodologia estabelecida pelo Standand Methods for the Examination of Water & Wastewater, 21ª ed. Concluiu-se que o período chuvoso apresentou contaminação, por coliformes, bactérias heterotróficas, Staphylococcus aureos e bactérias sulfitos redutoras, enquanto que no período de seca a maioria das amostras não apresentou contagem bacteriológica. O consumo dessas águas representa risco à saúde da população.

Abstract The Aracaju Expansion Zone presents problems related to lack of water in adequate conditions of quantity and quality. The low purchasing power of the local community has led residents to excavate shallow wells in their homes to ensure water supply, the only alternative for domestic consumption, but untreated. The objective of this work was to evaluate the quality of well water and the scenarios of health risk, through microbiological analyses. The collections were carried out in the period from December 2015 to August 2017, according to the methodology established by Standard Methods for the Examination of Water and Wastewater, 21st ed. It was concluded that in the rainy season, the well water presents contamination by coliforms, heterotrophic bacteria, Staphylococcus aureos and sulfite reducing bacteria, while in the dry season most of the samples did not present bacteriological counts

ABSTRACT BACKGROUND: Sports participation plays an important role in bone gain during childhood and adolescence. The aim here was to identify sex-related determinants of bone mineral density (BMD) differences between male and female adolescents, with emphasis on the role of sports participation. DESIGN AND SETTING: Longitudinal study conducted in a public university in Presidente Prudente, Brazil. METHODS: The sample comprised 48 adolescents aged 11-17 years, of both sexes, who were matched according to sex, age and sports participation. BMD was the main outcome, while muscle mass, sports participation, calendar age and biological maturation were treated as covariates. Participants were followed up after nine months. RESULTS: At baseline, BMD values were similar between the sexes. However, adjustment for covariates showed that BMD was higher among girls at all sites, with a contribution from lean soft tissue (LST) in the model (partial eta-squared, ES-r = 0.619 in upper limbs; 0.643 in lower limbs; 0.699 in spine; and 0.599 in whole body). Sports participation only explained the upper-limb variance (ES-r = 0.99). At the follow-up, the results resembled the baseline except in the lower limbs (P = 0.109), in which BMD was similar between the groups. BMD gain over time was similar between girls and boys in all segments, and baseline LST affected upper-limb and whole-body BMD accrual (ES-r = 0.396 and 0.107, respectively). CONCLUSION: Whole-body and specific-site BMD differed between baseline and follow-up. However,BMD accrual was similar between the sexes, given that muscle mass constituted the most relevant determinant of the difference between them.
