ABSTRACT Numerous works and clinical research conducted in various institutions have cast fresh light on the notion of trauma and have contributed to the emergence of the concept of early relational trauma. Early relational trauma is a form of trauma rendered complex by the multiplicity of its sources and its modes of expression. Its main features are often attachment and acting-out disturbances. In families where such trauma occurs, links could sometimes be perverted and form a narcissistic configuration. This mode of functioning, organized around negativity, impacts the plurality of psychic processes and interferes with the treatment approaches of multidisciplinary teams. In order to promote a multifocal approach to care tailored to differences in situations, educational and socio-judicial practitioners. expression actingout acting out disturbances occurs configuration functioning negativity teams situations sociojudicial socio judicial practitioners

Abstract The golden mussel (Limnoperna fortunei) is an aggressive invasive species in South America, where it endangers native species and freshwater ecosystems, in addition to causing extensive economic losses, mainly to the hydroelectric sector. Currently, there’s no efficient control method available and the invasion has progressed across the continent. Its high reproduction rate is one of the key factors of the golden mussel’s high invasive potential and, recently, efforts have been done in order to understand the reproduction and the sexual features of this species. However, its cytogenetics characterization is incipient and the possible occurrence of sex-specific cytogenetic features was never investigated. In this study, we aimed to characterize the chromosomal morphometry, the distribution profile of heterochromatin, and to detect possible sex-related epigenetic marks in the golden mussel. Results revealed that the karyotypic structure is similar in both sexes and no chromosome heteromorphism was observed between males and females specimens. The data increment the cytogenetic characterization of Limnoperna fortunei and contribute for future studies that aim to further investigate its reproduction and underlying sex determination processes.

The Kruger National Park's (KNP) long-running experimental burn plots (EBPs) have a history of research projects, which improve the understanding of fire in savanna ecosystems. Using data from KNP's aerial censuses (2005-2016) and in situ dung count data (2008-2017), this study assessed (1) herbivore densities on the Satara, N'Wanetsi and Marheya EBPs, on annual, triennial and no-burn treatments and across pre-, during and post-drought climate conditions; (2) herbivore densities of these EBPs relative to their non-manipulated surroundings and (3) the extent to which distance to water and rainfall influence ungulate densities. The results revealed that herbivore mean density differed significantly between the three EBPs of Satara and across their fire treatments. N'Wanetsi showed the highest density (0.30 animals/ha), whilst the lowest was found at Marheya (0.12 animals/ha). Overall, pre-drought density was higher on the annual plots (0.56 animals/ha), whilst higher post-drought density was evidenced on the triennial plots (0.80 animals/ha). On average, there were significantly higher herbivore densities on the EBPs (2.54 animals/ha) compared to the surrounding matrix at the larger scales of the Satara management section (0.15 animals/ha) and the central KNP (0.18 animals/ha). A positive correlation between herbivore mean density estimate and distance to water was shown. However, grazer mean density across fire treatments was strongly correlated to rainfall. CONSERVATION IMPLICATIONS: Given the variation in fire regimes and their application, and the non-uniform and elevated herbivore densities of the EBPs, inferences from the EBPs cannot be made to the larger KNP. The trials should rather be viewed as an isolated, fire herbivory experiment. It is also recommended to align the experiment with South African National Parks' mandate by including biodiversity parameters like small mammals and insects in the monitoring of the plots.

BACKGROUND: The Vegetation Map of South Africa, Lesotho and Swaziland (National Vegetation Map [NVM]) is a fundamental data set that is updated periodically. The National Biodiversity Assessment (NBA) 2018 process provided an opportunity for a more comprehensive revision of the NVM and better alignment between the terrestrial, marine and estuarine ecosystem maps OBJECTIVES: The aim of this study was to update the NVM 2018 and quantify spatial and classification changes since NVM 2012, and describe the rationale and data sources utilised. We also quantified spatial errors corrected in this version, highlighted progress since NVM 2006, and identified errors and gaps to make recommendations for future revisions METHOD: Edits made to the NVM in ArcMap 10.4 were categorised into the following five groups for analysis: (1) New types, (2) Boundary edits, (3) Realm re-assignment, (4) Removed and replaced vegetation types and (5) Deleted map area. Changes were quantified by category and biome. We used various software platforms to correct and quantify spatial errors since 2006 RESULTS: Vegetation types were added (n = 47), removed (n = 35) and had boundary edits (n = 107) in NVM 2018, which affected over 5% of the total map area, compared to 2.6% (2012) and 0.5% (2009) for previous versions. Several sources of error were identified and fixed, and prompted the development of standard mapping protocols CONCLUSION: National Vegetation Map 2018 is the most substantial revision of this data set that now fully aligns with maps of all other realms that form part of the NBA. However, parts of the map remain unrefined and provide opportunities for future work

RESUMO O eritrograma é um dos componentes do hemograma que inclui a quantificação e a avaliação eritrocitária. Uma correta interpretação e validação dos resultados obtidos em um eritrograma requer experiência e sentido crítico dos profissionais de saúde. Torna-se imperativo avaliar a interferência de variáveis fisiológicas e de colheita, a manipulação das amostras e as variáveis endógenas (como a presença de crioaglutininas), uma vez que estas podem falsear os resultados obtidos. As crioaglutininas são autoanticorpos predominantemente do tipo imunoglobulina da classe M (IgM), as quais provocam aglutinação dos eritrócitos a temperaturas inferiores a 37°C, podendo aparecer em casos de anemia hemolítica autoimune e pneumonias atípicas, entre outras patologias. A presença de aglutinação eritrocitária interfere na contagem de eritrócitos, reticulócitos, determinação do volume globular e dos índices hematimétricos. Laboratorialmente, existe um conjunto de procedimentos que podem ser executados de modo a eliminar a interferência dessas aglutininas nos resultados do eritrograma. Caso esses procedimentos não corrijam os valores obtidos, o único resultado do eritrograma que poderá ser validado é o da hemoglobina, visto que os resultados restantes estão falseados devido à presença de crioaglutininas.

ABSTRACT The erythrogram is one of the components of the blood count that includes red blood cell (RBC) quantification and evaluation. A correct interpretation and validation of the results obtained in an erythrogram require experience and critical awareness of health professionals. It is imperative to evaluate the interference of physiological variables, collection procedures, manipulation of samples and endogenous variables (such as the presence of cold agglutinin autoantibodies), since these may falsify the results obtained. Cold agglutinin autoantibodies are predominantly immunoglobulin type M (IgM), which cause agglutination of RBC at temperatures below 37°C, and may appear in cases of autoimmune hemolytic anemia and atypical pneumonia, among other pathologies. The presence of erythrocyte agglutination interferes with RBC and reticulocyte counts, determination of the globular volume and the blood count indices. A set of laboratorial procedures may be performed in order to eliminate the interference of these agglutinins in the results of the erythrogram. If these procedures do not correct the values obtained, the only result of the erythrogram that can be validated is hemoglobin, since the remaining results are falsified due to the presence of cold agglutinin autoantibodies.

BACKGROUND: Predicting which alien species may become invasive is important in prioritising scarce resources for management. OBJECTIVES: Sixteen naturalised ornamentals in Cape Town were assessed for invasion potential in relation to a mechanistic framework. The recently spreading species, Centranthus ruber (L.) DC., was studied in detail following management actions and vegetation fires. METHOD: The mechanistic framework was developed using nine features most likely to promote invasiveness. Species were assessed from their known characteristics, local usage and distribution records, including citizen science surveys. Surveys were conducted for C. ruber to assess its ability to survive and spread post-fire. Control efficacy for Centranthus ruber was assessed in plots at two sites. RESULTS: Nine species with more than 25 naturalisation records had a median of seven features that promote invasion compared to five features in the less recorded group of seven species. Centranthus ruber was widespread in modified urban habitats and persisted in natural habitats following vegetation fires and is a high priority for control. Post-fire mechanical and chemical control of C. ruber significantly reduced its density and cover, but did not eliminate it. CONCLUSION: Naturalised ornamentals can move rapidly from latent to invasive phases; therefore, monitoring should start during the latent phase to detect sudden change. In fire-driven ecosystems it is essential to have good pre-fire baseline data. More residents should be encouraged to become spotters through citizen science programmes and to report new naturalised ornamentals. It is important to act early in the invasion process and to allocate sufficient resources, if a newly invasive species is to be contained.

RESUMO: O objetivo deste estudo foi determinar as características físico-químicas do pólen coletado pelas abelhas amazônicas sem ferrão, Melipona seminigra e Melipona interrupta , para verificar se suas características atendem aos requisitos físico-químicos estabelecidos no Regulamento Técnico Brasileiro de Identidade e Qualidade de Pólen Apícola. As análises físico-químicas foram realizadas através de métodos analíticos oficiais. Os resultados das análises do pólen coletado por M. seminigra e M. interrupta foram, respectivamente: umidade: 53,39 e 37,12%; proteínas: 37,63 e 24,00%; lipídeos: 10,81 e 6,47%; cinzas: 4,03 e 2,74%; fibra bruta: 9,30 e 13,65%; carboidratos: 25,66 e 44,27%; energia: 350,47 e 331,33kcal%; pH: 3,70 e 3,34; sólidos totais: 46,60 e 62,87%; e atividade de água: 0,91 e 0,85. O percentual de umidade e o pH do pólen coletado por ambas as abelhas estudadas está em desacordo com o Regulamento Técnico para pólen apícola. Recomendamos que sejam realizados mais estudos para melhor caracterizar este produto e atualizar o Regulamento vigente, se necessário, pois algumas características que não atendem ao Regulamento são inerentes ao pólen de Melipona.

ABSTRACT: The purpose of this study was to determine the physicochemical characteristics of pollen collected by the Amazonian stingless bees Melipona seminigra and Melipona interrupta , in order to verify whether their characteristics meet the physicochemical requirements established by the Brazilian Technical Regulation for Identity and Quality of Bee Pollen. Physicochemical analyses were performed through official analytical methods. Results of pollen analyses collected by M. seminigra and M. interrupta were respectively as follows: moisture: 53.39 and 37.12%; protein: 37.63 and 24.00%; lipids: 10.81 and 6.47%; ash: 4.03 and 2.74%; crude fiber: 9.30 and 13.65%; carbohydrates: 25.66 and 44.27%; energy: 350.47 and 331.33kcal%; pH: 3.70 and 3.34; total solids: 46.60 and 62.87%, and water activity: 0.91 and 0.85. The percentages of moisture and pH in pollen collected by both studied bees are not in agreement with the Technical Regulation for bee pollen. Since some characteristics, which are inherent to the Melipona pollen, were not in conform to the current Regulation, we recommend that further studies should be conducted to better characterize it, and correct the Regulation, if necessary.

The main objective of the present work was to validate a chromatographic method to determine herbicides commonly applied in the irrigated rice farming. For this, matrix-matched calibration was employed along with the extraction and clean-up of the samples by quick, easy, cheap, effective, rugged and safe (QuEChERS) method and determination of the analytes by high performance liquid chromatography tandem mass spectrometry (LC-MS/MS) with electrospray ionization in the positive mode. By this method, it was possible to achieve the ionization and detection of a total of 18 herbicides, with quantification of 12 of them. The method presented adequate precision and accuracy according to the European Commission and the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) guidelines for analytes in low concentrations. The limits of quantification ranged from 0.015 μg g-1 for oxadiazon to 0.165 μg g-1 for imazapyr. The method showed good linearity with R2> 0.99 and recovery values from 92 to 103%. The proposed protocol is adequate for monitoring bispyribac-sodium, cyclosulfamuron, cycloxydim, clomazone, ethoxysulfuron, fenoxaprop-p-ethyl, imazapic, imazapyr, imazethapyr, metsulfuron-methyl, oxadiazon and thiobencarb in rice grains in concentrations up to 109 times lower than the maximum residue limits established by the Brazilian Health Surveillance Agency (ANVISA) for these compounds in rice samples.

Abstract This work describes the antimicrobial, antioxidant and anticholinesterase activities in vitro of organic extracts from fourteen seaweeds, eleven sponges, two ascidians, one bryozoan, and one sea anemone species collected along the Brazilian and Spanish coast, as well as the isolation of the diterpene (4R, 9S, 14S)-4α-acetoxy-9β,14α-dihydroxydolast-1(15),7-diene (1) and halogenated sesquiterpene elatol (2). The most promising antimicrobial results for cell wall bacteria were obtained by extracts from seaweeds Laurencia dendroidea and Sargassum vulgare var. nanun (MIC 250 μg/ml), and by the bryozoan Bugula neritina (MIC 62.5 μg/ml), both against Staphylococcus aureus. As for antimollicutes, extracts from seaweeds showed results better than the extracts from invertebrates. Almost all seaweeds assayed (92%) exhibited some antimicrobial activity against mollicutes strains (Mycoplasma hominis,Mycoplasma genitalium,Mycoplasma capricolum and Mycoplasma pneumoniae strain FH). From these seaweeds, A1 (Canistrocarpus cervicornis), A11 (Gracilaria sp.) and A4 (Lobophora variegata) showed the best results for M. pneumoniae strain FH (MIC 250 μg/ml). Furthermore, compounds 1 and 2 were also assayed against mollicutes strains M. hominis,M. genitalium,M. capricolum,M. pneumoniae strain 129 and M. pneumoniae strain FH, which showed MIC > 100 μg/ml. Antioxidant activities of extracts from these marine organisms were inactive, except for E7 (from sponge Ircinia sp.), which exhibited moderated antioxidant activities for two methods assayed (IC50 83.0 ± 0.1 μg/ml, and 52.0 ± 0.8 mg AA/g, respectively). Finally, for the anticholinesterase activity, all the 29 samples evaluated (100%) exhibited some level of activity, with IC50 < 1000 μg/ml. From these, seaweeds extracts were considered more promising than marine invertebrate extracts [A10 (IC50 14.4 ± 0.1 μg/ml), A16 (IC50 16.4 ± 0.4 μg/ml) and A8 (IC50 14.9 ± 0.5 μg/ml)]. The findings of this work are useful for further research aiming at isolation and characterization of active compounds.

Objetivo verificar as mudanças quantitativas na dinâmica da deglutição em pacientes portadores da doença de Parkinson, submetidos à administração de riboflavina e restrição de carnes vermelhas e de aves, no período de um ano. Métodos participaram do estudo 16 pacientes com doença de Parkinson, com media de idade de 67,25 anos, media do nível de severidade da doença de II para III e com media de 3,5 anos de tempo de diagnóstico da doença. As avaliações videofluoroscópicas da deglutição foram realizadas antes e após um ano de administração de riboflavina e restrição de carne vermelha e de aves. Foram analisadas presença de queixas relacionadas à deglutição e análise quantitativa por meio de medidas computadorizadas do deslocamento do osso hióide e da cartilagem cricóidea, abertura da transição faringoesofágica (TFE) e da constrição da faringe. Resultados verificou-se redução no percentual de queixas relacionadas à deglutição no momento pós-administração de riboflavina. Com relação às medidas quantitativas, observou-se no momento pós um discreto aumento na abertura da TFE para todas as consistências oferecidas, aumento da constrição da faringe para a consistência líquido engrossado, discreta redução dos valores de deslocamento do osso hióide, e tanto discreta redução como discreto aumento dos valores de deslocamento da cartilagem cricóidea dependendo da consistência alimentar, sendo redução significante para o líquido. Conclusões as medidas quantitativas realizadas na movimentação dos órgãos relacionados à deglutição não demonstraram diferenças significantes entre os momentos pré e pós-riboflavina e a restrição de carne vermelha e de aves.

Purpose to verify the quantitative changes in the swallowing dynamics in patients with Parkinson´s disease submitted to treatment with riboflavin, red meat and poultry removed during one year period. Methods sixteen patients with Parkinson´s disease participated in the study; the mean age was 67.25 years, the mean degree of disease severity was II to III, and the mean time since the diagnosis of the disease was 3.5 years. Videofluoroscopic evaluations were performed before and one year after treatment with riboflavin and diet with restriction of read meat and poultry. Analyzed were presence of complaints related to swallowing and quantitative analyses of swallowing includind computerized measurements of hyoid bone and cricoid cartilage displacement, opening of the superior esophageal sphincter and pharyngeal constriction. Results decrease of complaints was observed after administration of riboflavin. About the quantitative measures after riboflavin, there were a increase in the opening of the superior esophageal sphincter for all consistencies offered, an increase in the pharyngeal constriction for the thickened liquid, a reduction in the hyoide bone displacement, and an increase or a reduction in the cricoid cartilage displacement for each consistency, with significant reduction for the liquid. Conclusion quantitative measurements made in the movement of organs associated with swallowing showed no significant differences between pre-and post-riboflavin, and red meat and poultry removed.

Em ecossistemas agrícolas, a avaliação da biodiversidade é extremamente importante dada a sua relação com a sustentabilidade, sendo contudo uma tarefa difícil e dispendiosa. O uso da relação entre o número de espécies e o número de táxones de alto nível, tem sido proposto como uma alternativa eficaz e económica para a avaliação da biodiversidade, contudo a sua utilização tem estado praticamente restringida aos ecossistemas naturais, mais estáveis. Neste estudo, testou-se o uso da relação entre o número de espécies e o número de táxones de alto nível em aranhas, em pomares de pêra sob diferentes modos de produção, na região Oeste de Portugal. As aranhas foram seleccionadas para este estudo de caso por serem importantes predadores, actuando como agentes de luta biológica contra pragas. Concluiu-se que o género pode ser usado na avaliação da riqueza de espécies, com um elevado grau de precisão.

In agroecosystems, the evaluation of biodiversity is extremely important given its relation with their sustainability, however it is a difficult and expensive task. The use of the higher taxa surrogacy has been proposed as an effective and less expensive way to assess biodiversity, but is still being used mainly in natural, more stable, ecosystems. In this study, we tested the use of the higher taxa surrogacy approach for spiders in pear orchards, under different production systems, in the “Oeste” region of Portugal. Spiders were chosen for this case study, since they are important predators, acting as biological control agents in agroecosystems. We concluded that genus can be used as a higher taxa surrogate of species richness with a good accuracy.

Apesar de a maioria dos doentes tratados com amiodarona permanecer em eutiroidia, alguns desenvolvem hipertiroidismo (HPEIA) ou hipotiroidismo (HPOIA) induzidos pela amiodarona. Os autores apresentam uma análise retrospectiva dos processos de dez doentes com disfunção tiróidea induzida pela amiodarona. Verificou-se que seis doentes eram mulheres e que o tempo médio de toma da amiodarona foi de 17,7 meses. O HPOIA foi o mais frequente (seis doentes). Dos doentes com HPEIA, dois tinham HPEIA tipo 2, um tipo 1 e um tipo 3. Sintomas sugestivos de disfunção tiróidea ocorreram em cinco doentes, a maioria com HPOIA. No HPEIA, a clínica mais comum foi exacerbação da arritmia de base (três doentes). A interrupção da amiodarona e administração de levotiroxina foi a terapêutica escolhida em 83,3% dos casos de HPOIA, enquanto a tionamida associada a corticoide com suspensão da amiodarona foi opção em 75% dos casos de HPEIA. Registraram-se três óbitos, todos com HPEIA. O HPEIA constituiu uma complicação potencialmente fatal. A clínica pode ser vaga, pelo que a monitorização da função tiróidea é obrigatória.

Although most patients remain clinically euthyroid, some develop amiodarone-induced hyperthyroidism (HPEAI) or hypothyroidism (HPOAI). The authors present a retrospective analysis of ten patients with amiodarone-induced thyroid dysfunction. Six patients were female and mean amiodarone intake was 17.7 months. HPOIA was more common (six patients). From all the patients with HPEAI, two had type 2, one had type 1, and one had type 3 hyperthyroidism. Symptoms suggestive of thyroid dysfunction occurred in five patients, most of them with HPOAI. In HPEAI, the most frequent symptom was exacerbation of arrhythmia (three patients). Discontinuation of amiodarone and treatment with levothyroxine was chosen in 83.3% of the HPOAI cases, while thyonamide treatment with corticosteroids and without amiodarone was the option in 75% of the HPEAI cases. There were three deaths, all in patients with HPEAI. HPEAI is potentially fatal. The clinical picture may be vague, so the thyroid monitoring is mandatory.

Nos últimos anos, os óleos essenciais vêm sendo intensamente estudados como fonte natural de novos agentes antimicrobianos. Neste trabalho, os óleos essenciais das folhas e galhos de Drimys angustifolia do sul do Brasil foram obtidos por hidrodestilação e analisados por cromatografias gasosas com detector de ionização de chama (GC-FID) e com espectrômetro de massa (GC-MS). Os constituintes drimenol e biciclogermacreno foram isolados por cromatografia em coluna do óleo essencial dos galhos e folhas, respectivamente. Os óleos, os constituintes isolados e combinações destes foram testados contra bactérias Gram-(+) e Gram-(-). Os óleos essenciais foram mais ativos contra Bacillus cereus, com MIC (concentração inibitória mínima) de 125 e 250 µg mL-1 para os galhos e folhas, respectivamente, inibindo fortemente o crescimento bacteriano. Biciclogermacreno foi mais ativo que drimenol, fornecendo um valor de MIC de 167 µg mL-1 contra B. cereus. Não foi observado qualquer efeito sinérgico nas combinações testadas.

Essential oils have been extensively studied in recent years as a natural source of new antimicrobial agents. In this work, essential oils of leaf and branch from Drimys angustifolia growing in Southern Brazil were obtained by hydrodistillation and analyzed by gas chromatographies with flame ionization detector (GC-FID) and with mass spectrometer (GC-MS). Drimenol and bicyclogermacrene were isolated by column chromatography from branch and leaf essential oils, respectively. Oils, isolated compounds and combinations of them were assayed against Gram-(+) and Gram-(-) bacteria. The oils showed to be more active against Bacillus cereus, with minimum inhibitory concentration (MIC) 125 and 250 µg mL-1 for branch and leaf oils, respectively, strongly inhibiting bacterial growth. Bicyclogermacrene was more active then drimenol, providing a MIC value of 167 µg mL-1 against B. cereus. Synergism was not observed in any of the combinations tested.

OBJETIVO: investigar fatores associados à retenção de peso pós-parto. MÉTODOS: estudo de coorte com 104 gestantes recrutadas em uma Unidade Básica de Saúde no município do Rio de Janeiro, da 8ª a 13ª semana de gestação e acompanhadas até aproximadamente 55 dias pós-parto. As variáveis incluíram informações sócio-demográficas, econômicas, bioquímicas, antropométricas e reprodutivas. A retenção de peso pós-parto (diferença entre o peso pós-parto e o peso pré-gestacional) foi utilizada como variável dependente. RESULTADOS: a média de peso retido foi 3,2 kg ± 3,7 kg. As mulheres com ganho de peso gestacional (GPG) excessivo retiveram 5,0 kg ± 3,9 em comparação a 3,6 kg ± 3,0 em mulheres com GPG adequado e 1,4 kg ± 3,1 para as com GPG insuficiente. O GPG e o Índice de Massa corporal (IMC) pré-gestacional mantiveram associação significativa com a retenção de peso no modelo final. Observou-se que a cada quilo de peso ganho na gestação, quase 50% ficaram retidos no pós-parto (β = 0,494; p<0,001) e a cada 1,0 kg/m² a menos no IMC pré-gestacional correspondeu a uma retenção de aproximadamente 150g (β = -0,149;p<0,05). CONCLUSÃO: o GPG está positivamente e o IMC pré-gestacional inversamente associado à retenção de peso pós-parto. Orientações nutricionais sobre o controle do ganho ponderal podem ajudar a minimizar a incidência de obesidade entre mulheres no pós-parto.

OBJECTIVE: to investigate factors associated with post-partum weight retention. METHODS: a cohort study with 104 recruited pregnant women in the 8th to 13th week of gestation was carried out at Basic Health Unit in the municipality of Rio de Janeiro and the women were accompanied until around 55 days post-partum. The variables included socio-demographic, economic, biochemical, anthropometric and reproductive data. Post-partum weight retention (the difference between postpartum andpre-gestational weight) was used as the dependent variable. RESULTS: the mean weight retention was 3.2 kg ± 3.7 kg. Women with excessive gestational weight gain retained 5.0 kg ± 3.9 in comparison to 3.6 kg ± 3.0 in women with adequate gestational weight gain and 1.4 kg ± 3.1 compared to those with inadequate gestational weight gain. The gestational weight gain and pre-gestational body mass index continued to show a significant association with weight retention in the final model. It was found that for every kilogram of weight gain during gestation, almost 50% was retained post-partum (β = 0.494; p<0.001) and every 1.0 kg/m² less in pre-gestational BMI corresponded to a retention of approximately 150g (β = -0.149; p<0.05). CONCLUSION: gestational weight gain is positively associated with post-partum weight retention, while pre-gestational BMI is inversely associated with the dependent variable. Nutritional advice on weight control may help minimize the incidence of obesity in women during post-partum.
