Minimally invasive repair of Morgagni hernia - A multicenter case series

Children may benefit from minimally invasive surgery (MIS) in the correction of Morgagni hernia (MH). The present study aims to evaluate the outcome of MIS through a multicenter study. National institutions that use MIS in the treatment of MH were included. Demographic, clinical and operative data were analyzed. Thirteen patients with MH (6 males) were operated using similar MIS technique (percutaneous stitches) at a mean age of 22.2±18.3 months. Six patients had chromosomopathies (46%), five with Down syndrome (39%). Respiratory complaints were the most common presentation (54%). Surgery lasted 95±23min. In none of the patients was the hernia sac removed; prosthesis was never used. In the immediate post-operative period, 4 patients (36%) were admitted to intensive care unit (all with Down syndrome); all patients started enteral feeds within the first 24h. With a mean follow-up of 56±16.6 months, there were two recurrences (18%) at the same institution, one of which was repaired with an absorbable suture; both with Down syndrome. The application of MIS in the MH repair is effective even in the presence of comorbidities such as Down syndrome; the latter influences the immediate postoperative recovery and possibly the recurrence rate. Removal of hernia sac does not seem necessary. Non-absorbable sutures may be more appropriate.

An Intriguing Case of Anaemia and Splenomegaly

Objectives: Thrombocytopenia and splenomegaly are common features in several haematological disorders. Gaucher disease (GD) is a rare lysosomal storage disorder frequently characterized by thrombocytopenia and splenomegaly, which represents a clinical challenge for haematologists and internists. Case: We describe the case of a 37-year-old patient with a diagnosis of spherocytosis since childhood, who developed hepatic failure and presented striking features of GD including hepatosplenomegaly, bone fractures and post-partum bleeding. We reconsidered the diagnosis of spherocytosis and investigated Gaucher disease. Conclusion: GD should be considered in the differential diagnosis of thrombocytopenia and splenomegaly.

Toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the developing male Wistar(Han) rat I: no decrease in epididymal sperm count after a single acute dose

It has been reported that fetal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes defects in the male reproductive system of the rat. We set out to replicate and extend these effects using a robust experimental design. Groups of 75 (control vehicle) or 55 (50, 200 or 1000 ng of TCDD kg-1 bodyweight) female Wistar(Han) rats were exposed to TCDD on Gestational Day (GD) 15, then allowed to litter. The high dose group dams showed no sustained weight loss compared to control, but four animals had total litter loss. Pups in the high dose group showed reduced body weight up till day 21, and pups in the medium dose group showed reduced body weight in the first week post partum. Balano-preputial separation (BPS) was significantly delayed in the high dose group male offspring. There were no significant effects of treatment when the offspring were subjected to a functional observational battery, or mated with females to assess reproductive capability. 25 males per group were killed on post natal day (PND) 70, and ~60 animals per group (~30 for the high dose group) on PND120 to assess seminology and other endpoints. At PND120, the two highest dose groups showed a statistically significant elevation of sperm counts, compared to control; however, this effect was small (~30%), within the normal range of sperm counts for this strain of rat, was not reflected in testicular spermatid counts nor PND70 data, and is therefore postulated to have no biological significance. Although there was an increase in the proportion of abnormal sperm at PND70, seminology parameters were otherwise unremarkable. Testis weights in the high dose group were slightly decreased at PND 70 and 120, and at PND120, brain weights were decreased in the high dose group, liver to body weight ratios were increased for all three dose groups, with an increase in inflammatory cell foci in the epididymis in the high dose group. These data show that TCDD is a potent developmental toxin after exposure of the developing fetus, but that acute developmental exposure to TCDD on GD15 caused no decrease in sperm counts.

Retratos da Guerra Civil Espanhola na obra de Juan Marsé

O conflito civil espanhol (1936-1939) teve consequências desastrosas para o país. No entanto, o período do pós-guerra foi igualmente difícil pela falta de valores, fragmentação de famílias, fome e miséria generalizada. Juan Marsé, escritor catalão, aborda invariavelmente o mesmo tema nas suas obras – a Barcelona do pós-guerra –, recuperando a memória desta fratura na História de Espanha. Deste modo, este artigo pretende analisar obras como Últimas tardes con Teresa, Si te dicen que caí ou Rabos de Lagartija e identificar paisagens físicas e humanas dessa época.

A prática baseada na evidência : a amamentação como fator preventivo da depressão pós-parto

Enquadramento: É expectável que o pós-parto seja um período de alegria. Todavia, nem sempre é assim, já que pode ser um período marcado por momentos de tristeza, cansaço e desânimo. Reconhecendo as vantagens da amamentação para a saúde e bem-estar do recémnascido e da mãe, acreditamos que esta possa ser preventiva da depressão pós-parto. Objetivos: Obter a melhor evidência científica para compreender se a amamentação tem efeito preventivo na depressão pós-parto. Método: Foi efetuada uma revisão integrativa da literatura sobre a relação entre a amamentação e a depressão pós-parto através das bases de dados: EBSCO host, LILACS, PubMed, SciELO, Repositórios institucionais e Google Académico. Selecionaram-se quinze artigos que obedeceram aos critérios de inclusão deste estudo. Resultados: A maioria dos estudos identifica a amamentação como sendo preventiva da depressão pós-parto, destacando a importância da amamentação para a saúde mental da puérpera e consequentemente para a diminuição das hipóteses de desenvolver depressão pósparto. Cinco artigos identificam-na também como sendo um fator de risco e um estudo não encontrou uma associação clara entre a amamentação e a depressão pós-parto. Conclusões: São descritos vários benefícios da amamentação, os quais terão um efeito preventivo contra a depressão pós-parto. Uma mulher informada e apoiada acerca da amamentação será capaz de se sentir confiante no seu novo papel. É essencial um investimento constante por parte da equipa de saúde, iniciado durante o processo do planeamento do casal para a gravidez, e mantendo-se ao longo da gravidez, parto e pós-parto. Palavras-chave: “Amamentação”, “depressão pós-parto”, “prevenção”.

Avaliação de megadoses de retinol palmitato no pós-parto imediato sobre o retinol do leite de puérperas atendidas no Hospital José Pedro Bezerra, Natal-RN

Vitamin A deficiency (VAD) is a serious public health problem in developing countries, and as a therapeutic and prophylactic measure retinil palmitate is being supplemented. Nevertheless its efficacy has been questioned. The objective of the study was to evaluate the supplementation of two retinil palmitate megadosis on the serum retinol levels of post partum healthy mothers from Dr. José Pedro Bezerra (Hospital Santa Catarina) hospital, Natal - RN. The enrolled women (n=199) were randomly distributed into three studied groups and supplemented with retinil palmitate immediately after delivery with a single 200,000 IU dose (group S1), two 200,000 IU dose (group S2) with 24h difference between the doses, or no supplementation (group C). Among women selected, 143 remained until the end of the study. The influence of vitamin A dietary intake was evaluated during pregnancy and after 30 days of delivery. The average intake of the population was reasonable, but a high prevalence of inadequate intake was found. Retinol in colostrums and mature milk was determined by high performance liquid chromatography (HPLC). The retinol average in colostrums and mature milk in the supplemented and control groups were adequate according to the reference values. In colostrums, women from groups C, S1 and S2 presented retinol averages by milk volume of 94.8 ± 40.2 µg/dL, 92.2 ± 50.0 µg/dL and 91.8 ± 53.7 µg/dL, respectively. No difference was found between these averages (p=0.965), this was also seen when the values where expressed as µg/g of fat (p=0.905). After 30 days of delivery, retinol per milk volume differed between the control group (36.6 ± 17.5 µg/dL) and groups supplemented with 200,000 IU (51.0 ± 28.8 µg/dL) or 400,000 IU (55.2 ± 31.6 µg/dL) of retinil palmitate (p<0,05). Nevertheless, when S1 and S2 groups where compared, no significant difference was found (p=0.97). Considering retinol/g of fat, the means were 12.7 ± 6.7 µg/g, 15.6 ± 8.3 µg/g and 17.2 ± 8.9 µg/g for groups C, S1 and S2, respectively, with significant difference between groups S2 and C (p=0,01). Subclinical VAD prevalence showed a serious public health problem in the study population (32% in colostrums and 31.5% in mature milk). When analyzing the groups separately, the group which received two doses (200,000 IU + 200,000 IU) presented the lowest VAD prevalence (20.7%). Retinil palmitate supplementations of 200,000 IU and 400,000 IU (divided in two doses) in the immediate post partum showed no significant difference. Nevertheless, the 400,000 IU (divided in two doses) supplementation showed a reduction in VAD

Avaliação da suplementação materna com megadose de vitamina A sobre os níveis de retinol e alfa-tocoferol no colostro

The vitamins A and E are recognizably important in the initial stages of life and the newborn depends on nutritional adequacy of breast milk to meet their needs. These vitamins share routes of transport to the tissues and antagonistic effects have been observed in animals after supplementation with vitamin A. This study aimed to verify the effect of maternal supplementation with vitamin A megadose (200,000 UI) in the immediate post-partum on the concentration of alpha-tocopherol in colostrum. Healthy parturient women attended at a public maternity natalensis were recruited for the study and divided into two groups: control (n = 37) and supplemented (n = 36). Blood samples of colostrum and milk were collected until 12 hours after delivery. The women of the supplemented group was administered a retynil palmitate capsule and 24 hours after the first collection was obtained the 2nd sample of colostrum in two groups for analysis of retinol and alpha-tocopherol in milk. The mean retinol concentration of 50,7 ± 14,4 μg/dL (Mean ± standard deviation) and alpha-tocopherol of 1217.4 ± 959 mg/dL in the serum indicate the nutritional status biochemical appropriate. Supplementation with retynil palmitate resulted in increase not only retinol levels in the colostrum of the supplemented group (p = 0.002), but also the concentration of alpha-tocopherol (p = 0.04), changing from 1456.6 ± 1095.8 mg/dL to 1804.3 ± 1432.0 mg/dL (milk 0 and 24 respectively) compared to values in the control group, 984.6 ± 750.0 mg/dL and 1175.0 ± 730.8 mg/dL. The women had different responses to supplementation, influenced by baseline levels of retinol in colostrum. Those with previous by low levels of retinol in colostrum (<60 mg/dL) had increased the concentration of alpha-tocopherol in milk, whereas those with adequate levels (> 60 mg/dL), showed a reduction after supplementation. Supplementation with retinol palmitate is an important intervention in situations of high risk for vitamin A deficiency, when considering the need to maternal supplementation, since the excess vitamin can offer unfavorable interactions between nutrients essential for the mother-child group

Le rôle des acides gras oméga-3 sur la balance énergétique, la régulation de l’appétit, l’état émotionnel et l’implication du récepteur GPR120

L’obésité est un facteur de risque lié à des problèmes physiques, émotionnels et comportementaux. Aujourd’hui, l’alimentation est composée d’un régime typiquement occidental «Western diet» qui est riche en acides gras saturés (AGS) et pauvre en acides gras polyinsaturés (AGPI) tel que les oméga-3 (N-3) et occasionnant un déséquilibre du ratio alimentaire N-6/N-3. Ce déséquilibre est une des causes de la prévalence des maladies mentales y compris celles des troubles de l'humeur et de l’anxiété. L’acide docosahexaénoïque (ADH, 22: 6 n-3) est l’acide gras (AG) le plus abondant dans le cerveau et son accumulation est particulièrement élevée pendant la période périnatale. Il joue un rôle important dans le développement neuronal et d'autres fonctions du cerveau tel l'apprentissage et la mémoire. Des perturbations de l’environnement périnatal peuvent influencer à très long terme l’avenir de la descendance en la rendant plus susceptible de développer des problèmes d’obésité dans un contexte nutritionnel riche. On ignore cependant si le déficit alimentaire chez la mère et particulièrement en ADH aura un impact sur la motivation alimentaire de la progéniture. L’objectif principal de cette thèse est d’étudier le rôle potentiel des N-3 sur la balance énergétique, la motivation alimentaire, la dépression et le niveau d’anxiété des descendants de souris mâles adultes assujetties à une alimentation riche en gras. Nos données ont démontré qu‘un régime maternel déficitaire en ADH durant la période périnatale incitait la descendance à fournir plus d’effort afin d’obtenir un aliment palatable. Ceci entraînerait un dérèglement de l’homéostasie énergétique en augmentant le gain de poids et en diminuant l’activité locomotrice tout en exacerbant le comportement de type anxieux dès que les souris sont exposées à un milieu obésogène. Les acides gras libres (AGL) sont des nutriments essentiels fonctionnant comme des molécules de signalisation dans le cerveau en ayant des récepteurs qui jouent un rôle important dans le contrôle du métabolisme énergétique. Parmi eux, on distingue un récepteur couplé à la protéine G (GPCR), le GPR120. Ce récepteur activé par les AGPI ω-3 intervient dans les mécanismes anti-inflammatoires et insulino-résistants via les N-3. Une mutation dans le gène GPR120 occasionnée par une réduction de l’activité de signalisation du gène est liée à l’obésité humaine. L'objectif premier de cette deuxième étude était d’évaluer l'impact de la stimulation pharmacologique de GPR120 dans le système nerveux central (SNC) sur l'alimentation, les dépenses d'énergie, le comportement de type anxieux et la récompense alimentaire. Nos résultats démontrent qu’une injection centrale aiguë d'agoniste GPR120 III réduit la prise alimentaire ad libitum et la motivation alimentaire pour un aliment riche en gras et en sucre; ainsi que les comportements de type anxieux. L’injection centrale chronique (21 jours) de ce même agoniste GPR120 III transmis par une pompe osmotique a démontré que les souris placées sous diète hypercalorique (HFD n’ont présenté aucune modification lors de la prise alimentaire ni de gain de poids mais qu’il y avait comparativement au groupe de véhicule, une réduction du comportement de type anxieux, que ce soit dans le labyrinthe en croix surélevé (LCS) ou dans le test à champ ouvert (OFT). L’ADH est reconnu pour ses propriétés anorexigènes au niveau central. De plus, la stimulation des récepteurs de GPR120 au niveau du cerveau avec un agoniste synthétique peut produire un effet intense intervenir sur le comportement lié à l'alimentation des rongeurs. Trouver une approche visant à contrôler à la fois la neuroinflammation, la récompense alimentaire et les troubles émotionnels aiderait assurément au traitement de l'obésité et du diabète de type 2.

Influência da suplementação de retinol palmitato sobre os níveis de vitamina A no leite de puérperas saudáveis

The tendency towards reduction of serum retinol levels, an existing placental barrier and the increase of retinol demand, are factors that place puerperal and lactating women at risk for Vitamin A deficiency. This micronutrient is an essential component of vital processes such as differentiation, cellular proliferation, and apoptosis. The objective of this study is to evaluate the effect of palmitate retinol supplementation (100.000UI) upon the milk retinollevels in puerperal women at the Januário Cicco University Maternity Hospital. This intervention has been adopted by the Ministry of Health since 2002. The longitudinal experiment was conducted with 106 puerperal women (68 comprised the supplemented group and 38 the control group). The High Performance Liquid Chromatography (HPLC) method was used to dose the retinol of the milk and serum samples, and the creamtocrit method to determine the milk fat levels. The retinol means for the colostrums were 99.0 ± 64.4 ug/dL and 160.1 ± 94,4 ug/dl 6 hours afier supplementation; 68.9 ± 33.5 ug/dL for the transitional milk, and 30.6 ± 15.2 ug/dL for the mature milk of the supplemented group. Ali the difterences between means were statistically significant. The difterence between retinol means in the control group were also significant, with these being greater in the colostrum, 88.6 ± 62.1 ug/dL with 61.9 ± 30.1 ug/dl in the transition milk and 32.9 ±32.9 ± 17.6 ug/dL in the mature milk. No significant difference was observed in the retinol means of the three types ot milk in the supplemented group when compared to their respective means in the control group. The prevalence in serum (35.1 % and 81.1 % for the cutting point 20 ug/dL, respectively) and in milk (51.4%) revealed vitamin A deficiency as a public health problem. COlostrum, transition, and mature milk tats varied similarly in the supplemented group (1,92 ± 0,96; 3,25 ± 1,27 and 3,31 ± 1,36 grams) and in the control group (1,87 ± 1,14; 3,25 ± 1,31 and 3,36 ± 1,67 grams), with an observed difference between the colostrum/transition milk and the colostrum/mature milk fats. No difference was observed between the groups. The study showed that the 200.000UI supplementation was not sufficient to increase the milk retinol to the desired levels nor to meet the demands of the mothers with deprived hepatic reserves. It is suggested that another similar dose be offered within 30 days or less, and within 2 months post-partum, while continual/y monitoring for possible pregnancy

The influence of ApoE genotype on the lipid profile and lipoproteins during normal pregnancy in a Southern African population.

Background: Pregnancy is associated with increases in fasting triglycerides and total cholesterol.1 ApoE isoforms are known to influence the concentration of cholesterol, with apoE2 homozygosity lowering and apoE4 homozygosity raising the cholesterol concentration compared with E3 homozygosity.2 The lipid profiles ApoE status and prevalence of small dense LDL species were evaluated for subjects attending an antenatal clinic. Results: Samples from 690 women aged between 16 and 42 years of age were analyzed during and after pregnancy. The fasting plasma triglyceride concentration (in mmol/L) was significantly higher in pregnancy (median = 1.5, IQR 1.0-2.0 vs median = 0.6, IQR 0.5-0.8 respectively, p < 0.0001). Similarly, the total cholesterol (in mmol/L) was increased during pregnancy (median=4.1, IQR 3.6-4.7 vs median 3.5, IQR 3.1-3.5, respectively p=0.0167). The median LDL cholesterol and HDL cholesterol did not change. Higher proportions of small density LDL species were seen during pregnancy compared to after pregnancy. The distribution of the LDL species during pregnancy and 6 weeks post-partum were significantly different p<0.0001 with the smaller species being much higher during pregnancy. Conclusion: ApoE4 genotype was associated with increased total cholesterol and LDL cholesterol concentrations during pregnancy. Pregnancy results in a reversible remodeling of LDL to smaller species, the significance of which is unknown but may indicate a predisposition to atherosclerosis

State and economy. William Beveridge and Walter Eucken's criticisms and proposals. (A historical comparative perspective)

The central problem that this paper addresses is the development of political economic thought, both in Germany and in Great Britain, related to the construction of societies in which the State had a role in ensuring levels of stability and economic security to its inhabitants, particularly during the late 1940s -- This article proposes a comparative historical perspective of political economic thought of the British economist William Beveridge and his German counterpart Walter Eucken -- The comparison is based on their critiques to the economic system and proposals on the role that the State should play in the economy -- The study of the ideas of both thinkers, their criticisms and proposals on economic and political issues, allows us to understand the set of ideas that influenced the development of the Welfare State of the post war period, both in Britain and Germany

Global trends in relative and absolute income inequality

Este documento muestra una visión general de las tendencias históricas de la desigualdad mundial de ingreso en términos absolutos y relativos -- Dependiendo del concepto usado, las tendencias de desigualdad difieren considerablemente -- La desigualdad entre países aumentó fuertemente durante el periodo 1820-2000 y ha comenzado a disminuir a principios del siglo veintiuno, independiente si es medido en términos relativos o absolutos -- La desigualdad dentro de los países, por el contrario, ha crecido especialmente fuerte en las últimas décadas: su tasa de crecimiento aceleró a partir de 1950 en términos absolutos y a partir de 1975 en términos relativos -- En términos absolutos la desigualdad global también se incrementó sustancialmente en el periodo post-1950, mientras en términos relativos la desigualdad global ha disminuido ligeramente en el mismo periodo

Ideologia da casa própria... sem casa própria: o Programa de Arrendamento Residencial na cidade de João Pessoa-PB

Brazilian Housing policy has always promoted homeownership. In 1999, a new form of housing promotion was set up in the country with the PAR (Programa de Arrendamento Residencial, or residential rental programme). This is a sort of leasing, in which a right to buy is granted at the end of contract. Again, with this, the final objective is homeownership. This dissertation aims at further understanding the role of PAR in the wake of the country s housing policies of the post-BNH period, analysing the case of João Pessoa, capital city of Paraíba state. By focusing in the city, it has been possible to analyse also the impact of the programme in the dynamics of the city s urban development. Accordingly, the analysis of PAR seeks to understand the programme s operational aspects as well as its location, urban and architectural aspects. The operational aspects refer to how the programme is operated, considering the differences to the other housing programmes in the country. The urban and architectural aspects refer to location, typology and construction characteristics of housing estates produced under the scheme. This study gives a general view of the country s recent housing policy and programmes and the specific characteristics of PAR, observing also its impacts in the city development

A edificação e consolidação do Estado Novo no concelho de Torres Vedras : do golpe militar do 28 de Maio de 1926 às Eleições Presidenciais de 13 de Fevereiro de 1949

A presente dissertação de mestrado procura abordar a edificação e consolidação do regime do Estado Novo no concelho de Torres Vedras, alicerçando a sua estrutura de análise, numa abordagem aos aspectos políticos, sociais e económicos, mais relevantes, do arco cronológico balizado entre Maio de 1926 e Fevereiro de 1949. É nosso propósito analisar, inicialmente, as mutações locais ocorridas após o golpe militar do 28 de Maio de 1926, que inaugura a Ditadura Militar (1926-1932). A compreensão desta problemática é estruturada, numa análise ao impacto daquela intentona junto da imprensa local, à designação das novas elites políticas locais e à significativa actividade da oposição local, desenvolvida até ao final de 1932. Esta abordagem inicial, mas fulcral na concretização dos objectivos, antecederá a análise à implantação das estruturas do Estado Novo (1933-1938) no concelho de Torres Vedras. A resposta a esta questão será dada, desde logo, através de quatro cenários de análise distintos. Em primeiro lugar, procura-se acompanhar a actividade das elites políticas locais e o que representavam no âmbito político-ideológico. Num segundo momento centra-se a nossa análise, na edificação do modelo corporativo e na implantação das organizações salazaristas (Legião e Mocidade Portuguesa). Num terceiro foco de análise, procuramos sintetizar a actividade da oposição local. Por fim, introduzimos a abordagem aos principais actos eleitorais da década de 30. Após a compreensão, da evolução política e institucional, ocorrida desde Maio de 1926, o início da 2.ª Guerra Mundial (1939-1945), força-nos a inflectir a análise do panorama político e institucional, para as questões económicas, sociais e ideológicas deste período. A abordagem, ao contexto internacional de guerra, é fulcral, para se compreender, de que forma o espaço territorial em estudo sentiu os efeitos do conflito. Pretende-se por um lado, esclarecer as dificuldades vivenciadas pela população local, por outro, compreender o alinhamento ideológico assumido em favor das potências em confronto. Paralelamente dar-se-á continuidade, à análise sobre a evolução corporativa local, assim como às movimentações da oposição clandestina. O último foco de abordagem recai na organização da oposição local no período do pós-guerra (1945-1949). É nosso objectivo, indagar, os contornos associados ao alinhamento das forças democráticas após o termo do conflito. Num primeiro momento, foca-se a análise, na caracterização da composição da comissão concelhia do Movimento de Unidade Democrática, surgido em Outubro de 1945, num contexto pré-eleitoral despoletado por uma aparente abertura do regime. Numa segunda conjuntura, que coincide com as Eleições Presidenciais de 13 de Fevereiro de 1949, aborda-se a constituição da comissão concelhia de apoio ao general Norton de Matos e analisa-se, as principais movimentações locais, em redor da aludida eleição.

Contribuição para o estudo sobre os efeitos da administração preventiva de cetamina em baixa dose em cirurgia ortopédica no cão

Dissertação de Mestrado Integrado em Medicina Veterinária
