Germinal matrix hemorrhages (GMHs) are typically seen in preterm neonates during the first 4 days of life. The authors encountered 2 children with late-onset GMH subsequent to ventriculoperitoneal (VP) shunt insertion for congenital hydrocephalus. Both children were delivered at full term with normal body weight, although they were compromised with the preceding hypoxic events prior to shunt insertion. The first case involved a female infant with severe craniofacial deformities. Because of aspiration pneumonia related to the comorbid upper airway stenosis, endotracheal intubation with intermittent mechanical ventilation was necessary. The associated congenital hydrocephalus was treated with VP shunt insertion when she was 35 days of age, and GMH was confirmed 1 week after shunt placement. During a period of conservative observation, the hemorrhage resolved without any neurological deterioration. The second case involved a male infant with a large intraparenchymal cyst on the left parietal portion. He was intubated for pneumonia at 1 month of age. He had associated congenital hydrocephalus that was progressive, and he was treated with VP shunting at 69 days of age, after his pneumonia had resolved. Postoperative GMH was confirmed, although hydrocephalus was well controlled by VP shunt insertion. Observed conservatively, he fared well and the GMH resolved. These 2 cases had unique features in common; both had congenital anomalies in the CNS and respiratory problems before shunting. The hypoxic insults on the residual germinal matrix layer and sudden decrease in CSF pressure may relate to the occurrence of these late-onset GMHs.

Background. The incidence of abortion in Ghana ranges from 27 per 1000 to 61 per 1000 women, causing gynecological complications and maternal mortality. The use of modern contraceptives and its associated factors among women aged 15–49 years have been documented. However, utilization of modern contraceptives specifically among women with induced abortion history is underreported. This study therefore aimed at determining the proportion and identifying predictors of contraceptives use in this underreported population. Methods. This study used secondary data from the 2017 Ghana Maternal Health Survey (GMHS) for the analysis. The analysis is on a weighted sample of 3,039 women aged (15–49 years) with a history of induced abortion. Both descriptive and inferential methods were employed. The chi-square test, univariate and multivariate logistic regression techniques were used to assess statistical associations between the outcome variable and the predictors. Statistical significance was set at 95% confidence interval and p values ≤0.05. Results. Out of the 3,039 participants, 37% (95% CI: 34.6, 38.84) used contraceptives. We identified women’ age, union, place of residence, knowledge of fertile period, total pregnancy outcomes, and region as strong significant (95% CI, p≤0.05) predictors of post induced abortion contraceptives use. Conclusion. Contraceptives use among this vulnerable population is low. Therefore, there is a need to provide widespread access to postabortion contraception services and enhance efforts to efficiently integrate safe abortion practices law into health services in Ghana.

Gelatin, as natural macromolecular material, has been used in biomedical fields widely. In this study, various injectable gelatins A, B, and their compound AB microsphere-based gels (A-GMGs, B-GMGs and AB-GMGs) were prepared through water-in-oil emulsion method for hemostasis, and the effects of blood coagulation in vitro and surgical hemostasis (a deep liver wound model) in vivo were evaluated. Furthermore, the influences of gelatin sorts, the size of microsphere, zeta potential (ZP) and viscoelastic properties on hemostasis were also assessed. Results showed that the gelatin microspheres (GMs) exhibited smooth surface, good sphericity and the particle size of a rough normal distribution. GMs carried negative charges and their electronegativity was stronger than that of gelatin A (GA) and gelatin B (GB) raw materials. Rheological analysis showed that a decreasing particle size of the microspheres led to stronger gel strength, and solid-like gels were exhibited under low stress conditions and liquid-like gels were exhibited under high stress conditions. The blood clotting time of B-GMGs was within 60 s, which exhibited a significantly higher blood clotting effect compared with control groups. The hemostasis assay in vivo showed that the gels had better hemostatic effect on a deep liver wound bleeding model compared with control groups, especially B-GMGs. However, in vivo and vitro hemostatic experiments, particle size of GMs had no obvious influence on the hemostatic effect of the gels. In addition, the CCK-8 assay of bone marrow mesenchymal stem cells of murine (mMSCs) indicated non-cytotoxicity of GMs for cells. These results demonstrated that the gelatin microsphere-based gels (GMGs) had potential to be an effective hemostatic material for intracavitary and deep wound bleeding in surgery.

Three orchard groundcover management systems (GMSs) were established in a newly planted apple (Malus domestica cvs. Liberty, Nova Easygro, and NY84828-12 on Malling 9 rootstock) orchard on a silty-clay loam soil (Aeric Ochraqualf). The GMSs were applied in 2-m-wide strips within tree rows as follows: 1) a 6-cm-thick mulch layer of composed manure, straw, sawdust, and vegetable plant wastes applied in May 1992 and 1994; 2) a “green manure” cover crop of canola (Brassica campestris cv. Humus) seeded in mid-August each year and tilled under the following May; and 3) Post-emergence applications of N-(phosphonomethyl) glycine (glyphosate) herbicide (2.0 kg a.i./ha) in mid-May and July each year. After 3 years of GMS treatments, apple tree growth and trunk cross-sectional area were similar in all three systems. Fruit yield and yield efficiency were greater in glyphosate and compost than in canola GMSs, and `Liberty' was the most productive cultivar. Topsoil N, P, K, Ca, Mg, Zn, and organic matter content were all substantially greater in the compost GMS. Leaf N, K, and P concentrations were consistently greater in trees in compost plots; leaf Ca, Mg, Cu, and Zn concentrations were lower in compost GMS. Weed growth was rank and difficult to control in the compost mulch, but this GMS substantially enhanced orchard soil fertility.

Annotation:

The field of Global Mental Health (GMH) aims to influence mental health policy and practice worldwide, with a focus on human rights and access to care. There have been important achievements, but GMH has also been the focus of scholarly controversies arising from political, cultural, and pragmatic critiques. These debates have become increasingly polarized, giving rise to a need for more dialogue and experience-near research to inform theorizing. Ethnography has much to offer in this respect. This paper frames and introduces five articles in this issue of Transcultural Psychiatry that illustrate the role of ethnographic methods in understanding the effects and implications of the field of global mental health on mental health policy and practice. The papers include ethnographies from South Africa, India, and Tonga that show the potential for ethnographic evidence to inform GMH projects. These studies provide nuanced conceptualizations of GMH's varied manifestations across different settings, the diverse ways that GMH's achievements can be evaluated, and the connections that can be drawn between locally observed experiences and wider historical, political, and social phenomena. Ethnography can provide a basis for constructive dialogue between those engaged in developing and implementing GMH interventions and those critical of some of its approaches.

Natural (hay, wood chips, recycled paper pulp) and synthetic (polypropylene film and polyester fabric) mulches were compared with mechanical tillage and residual herbicides as orchard groundcover management systems (GMSS). In two New York orchards-the Clarke farm and Hudson Valley Lab (HVL—GMSS were applied from 1990 to 1993 in 1.8-m-wide strips under newly planted apple (Malus domestica; `Liberty', `Empire', `Freedom', and advanced numbered selections from the disease-resistant apple breeding program at Geneva, N.Y.) trees. GMS impacts on soil fertility, tree nutrition and growth, yields, crop value, and vole (Microtus spp.) populations were evaluated. After 3 years at the Clarke orchard, extractable NO3, Mn, Fe, B, and Zn concentrations were greater in soil with herbicides than synthetic mulches; soil K and P concentrations were greater with herbicides and wood chips than synthetic mulches. At the HVL orchard, topsoil NO3, K, and Mg concentrations were greater with hay mulch than herbicides or other mulches; Mg, Fe, and B concentrations were lower in soil with wood chips than other GMSs. Soil organic matter content was not affected by GMS. Apple leaf N, K, Cu, and Zn concentrations were greater with herbicides, hay mulch, and polypropylene mulch than cultivation or recycled paper mulch at the HVL orchard during hot, dry Summer 1991. Despite transient differences among GMSS during the initial years, after 4 years of treatments there were no consistent GMS trends in cumulative tree growth or gross yields. The higher establishment and maintenance costs of several mulches were offset by their prolonged efficacy over successive years; crop market values from 1992 to 1994 were considerably greater for trees with polypropylene film, polyester fabric, and hay mulches than herbicides, cultivation, or other mulches. Voles caused more serious damage to trees in synthetic and hay mulches, despite the use of mesh trunk guards and rodenticide bait.

Annotation:

Non-point source water pollution by agrichemicals is a recognized problem that has been studied in agronomic crop systems, and simulated using computer models or artificial soil columns, but rarely measured at field scale in orchards. For three growing seasons, we monitored the movement of nitrate and pesticide analogs and a widely used fungicide (benomyl) in two apple orchards under four different groundcover management systems (GMSs), including turfgrass, wood-chip mulch, residual pre-emergence herbicides, and post-emergence herbicide treatments. In subsoil lysimeter samplers at one orchard, we observed that nitrate and pesticide analogs leached more rapidly and in higher concentrations under herbicide plots compared with turfgrass plots. At another orchard where subsoil leaching and surface runoff of benomyl and nitrate-N were monitored in replicated GMS plots, we observed higher concentrations of benomyl (up to 30 μg·liter–1) and nitrate-N up to 50 μg·liter–1) leaching under herbicide GMS. The highest benomyl concentrations (375 μg·liter–1) and most frequent runoff of this pesticide were observed in the residual pre-emergence herbicide plots. Yearly weather patterns, irrigation, and development of different soil physical conditions under the four GMSs determined the relative magnitude and frequency of agrichemical leaching and runoff in both orchards. The agrichemicals apparently leached by mass flow in preferential flowpaths such as old root channels and soil cracks, while surface chemical runoff occurred mostly adsorbed on eroding soil sediment. These observations indicate that orchard GMSs can have a significant impact on leaching and runoff of pesticides and nutrients.

Purpose This study aims to explore the role General Managers (GMs) play in mitigating the effects of the unprecedented COVID-19 pandemic. Design/methodology/approach Qualitative structured interviews conducted online with 50 hospitality GMs from 45 countries are used to explore the impact of the pandemic on the industry’s operational norms and the role of managers in both managing the crisis and planning contingencies for recovery. Findings The findings enhance the conceptual capital in this emerging field and provide insights on how GMs behave during crises. Four related sub-themes emerged from the data analysis, namely, contingency planning and crisis management, resilience and impact on GM roles, the impact on hotels’ key functional areas and some GMs’ suggestions for the future of luxury hospitality. Research limitations/implications This study generates empirical data that inform contemporary debates about crisis management and resilience in hospitality organizations at a micro-level operational perspective. Practical implications Findings suggest that, in times of uncertainty and crisis, luxury hotel GMs are vital in coping with changes and leading their organizations to recovery. GMs’ resilience and renewed role and abilities enable them to adapt rapidly to external changes on their business environment. Originality/value This study is unique in terms of scale and depth, as it provides useful insights regarding the GM’s role during an unprecedented crisis such as COVID-19.

Groundcover management systems (GMSs) are essential for fruit production, but very few long-term studies have evaluated orchard GMS sustainability. We evaluated four GMSs—pre-emergence soil-active herbicides (PreHerb), post-emergence herbicide (PostHerb), a turfgrass cover crop (Sod), and hardwood bark mulch (Mulch)—in an apple (Malus domestica Borkh.) orchard over 16 years of continuous observation. There were no consistent long-term trends in fruit yields among GMSs, although during the first 5 years, yields were lower in trees on Sod. Tree growth was greater in PostHerb and Mulch than in Sod during the first 5 years, and during the next decade, trees in Mulch plots were consistently larger than in other GMSs. Total soil nitrogen (N) and carbon (C) content, C-to-N ratios, and essential plant nutrients were much greater in the Mulch soil after 16 years of treatments. Long-term responses of trees to groundcover vegetation indicated that apple trees respond adaptively to compensate for weed and grass competition. Year-round elimination of surface vegetation with residual soil active herbicides may be unnecessary or even detrimental for orchard productivity and soil fertility in established orchards. Post-emergence herbicides that reduce weed competition primarily during the summer months may offer an optimal combination of weed suppression and soil conservation.

We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified in the SPT-SZ survey, a millimeter-wave survey of 2500 deg(2) of the southern sky using the South Pole Telescope (SPT). Multi-object spectroscopic observations of 62 SPT-selected galaxy clusters were performed between 2011 January and 2015 December, yielding spectra with radial velocity measurements for 2595 sources. We identify 2243 of these sources as galaxies, and 352 as stars. Of the galaxies, we identify 1579 as members of SPT-SZ galaxy clusters. The primary goal of these observations was to obtain spectra of cluster member galaxies to estimate cluster redshifts and velocity dispersions. We describe the full spectroscopic data set and resulting data products, including galaxy redshifts, cluster redshifts, and velocity dispersions, and measurements of several well-known spectral indices for each galaxy: the equivalent width, W, of [O II] lambda lambda 3727, 3729 and H-delta, and the 4000 angstrom break strength, D4000. We use the spectral indices to classify galaxies by spectral type (i.e., passive, post-starburst, star-forming), and we match the spectra against photometric catalogs to characterize spectroscopically observed cluster members as a function of brightness (relative to m*). Finally, we report several new measurements of redshifts for ten bright, strongly lensed background galaxies in the cores of eight galaxy clusters. Combining the SPT-GMOS data set with previous spectroscopic follow-up of SPT-SZ galaxy clusters results in spectroscopic measurements for >100 clusters, or similar to 20% of the full SPT-SZ sample.

This prospective/retrospective study comprises 98 children with non-Hodgkins lymphoma diagnosed between 1981 and 2006 (26 years) at the Hospital das Clínicas, Federal University of Minas Gerais. Prognostic factors for surviving the disease were analyzed. The immunohistochemistry contribution to increase the accuracy of the diagnosis was also evaluated. The majority of patients were males (male/female ratio 2.3). The median age at diagnosis was 70 months (range 8.4 to 189.5 months). Malnutrition was defined as a Z score -2 (2 standard deviation below the median for the reference WHO population). Taking into consideration the weight-for-age Z score, 20.2% of children were considered malnourished; for the height-for-age Z score the frequency was 8.2%. An abdominal mass was the commonest form of presentation (49%). WHO histologic classification and the staging devised by St. Jude Childrens Research Hospital was used throughout. Burkitts lymphoma was the most frequent histologic type (52%) and the majority of patients presented as advanced stage at diagnosis (70.2%). Follow up varied from 0.1 to 26.3 years (median 6.1y) for those who did not die. Complete clinical remission rate was 83.7%. The estimated probabilities of overall survival and event free survival at 5 years were 73% (SE 4.4%) and 72% (SE 4.7%), respectively. Death during induction (n = 14) were due to infections and severe metabolic disturbances. Relapses occurred in 5 patients, all localized to central nervous system (4 isolated and one combined with marrow relapse). Up to 1987 modified Sloan-Kettering LSA2L2 protocol was adopted for treatment (n = 20). From 1987 onwards BFM-based protocols were employed. In univariate analysis significant prognostic factors for dying were increased levels of serum uric acid and urea at diagnosis (P < 0.001 and P = 0.03, respectively), advanced stage (P = 0.014) and the way histologic specimen for diagnosis was obtained (partial versus total ressection; P = 0.03). Gender, age, nutritional status, histologic type, serum levels of LDH, type of treatment protocol, or response to treatment were not statistically significant prognostic factors. Improving the accuracy of the morphologic diagnosis with immunohistochemistry was not either associated with a higher probability of survival.
A população deste estudo prospectivo/retrospectivo foi constituída de 98 crianças com diagnóstico de linfoma não-Hodgkin, diagnosticadas no Hospital das Clínicas da Universidade Federal de Minas Gerais no período de 1981 a 2006 (26 anos). Fatores prognósticos com possível influência na sobrevida foram analisados. Foi também avaliada a contribuição da imunohistoquímica na precisão do diagnóstico histológico. A maioria dos pacientes pertencia ao gênero masculino (relação masculino/ feminino igual a 2,3). A idade mediana dos pacientes ao diagnóstico foi de 70 meses (variação de 8,4 a 189,5 meses). Para caracterizar a desnutrição, adotou-se o ponto de corte de Z = -2 (dois desvios-padrão abaixo da mediana da população de referência da OMS). Em relação ao peso para a idade, 20,2% eram desnutridos e, em relação à estatura para a idade, 8,2%. A apresentação tumoral abdominal foi a mais frequente (49%). Foi utilizada a classificação histológica da Organização Mundial da Saúde e o sistema de estadiamento do St. Jude Childrens Research Hospital. O tipo histológico mais freqüente foi o linfoma de Burkitt (52%) e a maioria dos pacientes tinha estadio avançado (70,2%). O tempo de seguimento variou de 0,1 ano a 26,3 anos (mediana de 6,1 anos), para aqueles que não evoluíram para o óbito. A taxa de remissão clínica foi de 83,7%. A probabilidade estimada da sobrevida global e da sobrevida livre de eventos aos cinco anos foi de 73% ± 4,4% e de 72% ± 4,7% (n = 95). Os óbitos durante a indução, causados por infecções e distúrbios metabólicos e hemorragia, foram os mais frequentes (n=14). As recidivas ocorreram em cinco crianças, todas localizadas no sistema nervoso central, sendo que uma concomitantemente na medula óssea. Até 1987, o tratamento adotado foi o protocolo LSA2L2 modificado (n=20). A partir de 1987 foram adotados os protocolos de tratamento baseado nos estudos do grupo alemão BFM. Na análise univariada dos fatores desfavoráveis de prognóstico para a sobrevida, foram significativas as variáveis: dosagens elevadas de ácido úrico e de ureia ao diagnóstico (p < 0,001 e 0,03 respectivamente), estadiamento avançado (p = 0,014) e o método para obtenção do espécime histológico (ressecção parcial versus total; p = 0,03). Não foi observada nenhuma influência prognóstica significativa das variáveis gênero, idade, estado nutricional, tipo histológico, dosagem sérica de LDH, tratamento empregado e resposta ao tratamento. O aperfeiçoamento do diagnóstico com a imuno-histoquímica completa não se associou significativamente com uma melhor sobrevida.

Neurologic complications in children with sickle cell anemia (SCA) are frequent. Approximately 11% of children and youths up to 20 years of age are at risk of stroke. Transcranial Doppler ultrasonography (TCD) is an important way of detecting risk of ischemic stroke. The aim of this study is to verify the incidence of stroke and altered TCD in children and determine possible risk factors. Methods: We analyzed a cohort of children selected by the Newborn Screening Program of MG, with SCA, born between March 1998 and December 2005 and followed at the Hemominas Foundation until May 2009. TCD was carried out in a randomized cross-section of 300 children. The examination followed STOP protocol, and used pulsed TCD with a 2 MHz probe. Children with mean blood flow velocity <170 cm/s for the middle cerebral artery, distal internal carotid and anterior cerebral artery were classified as low risk; if velocity was of 170-184 cm/s, lower intermediate risk; if velocity was of 185-199 cm/s, higher intermediate risk; and if of 200 cm/s, high risk. Results: mean age of 6.5 years (2-10y); 150 female.194 children (75.6%) were classified as low risk; 19 (7.4%) as lower intermediate risk; 7 (2.6%) as higher intermediate risk; and 8 (3.1%) as high risk; 11.2% of the examinations were considered inadequate. Those 7 children of high risk, after being submitted to confirmatory examinations, started a regimen of chronic transfusion and one of them of hydroxyurea. Another, considered low risk, had a hemorrhagic stroke (normal brain angiography). 13 children (4.8%) had suffered from ischemic stroke prior to having the TCD. Alterations in TCD or clinical stroke were observed in children with a lower mean age (p=0.002). The accumulated probability of having a stroke before age 10 was of 9.5%; of having stroke+altered TCD (intermediate and high risk) was of 38.4%. There was no difference between children with normal TCD and those with altered TCD+stroke in the anthropometric analysis (comparison between mean Z score at age 3), occurrence of acute splenic sequestration (p=0.13) and acute chest syndrome (p=0.16). Mean hemoglobin concentration was lower in children with altered TCD+stroke (p<0.001); mean white blood cell and reticulocyte counts were higher in children with altered TCD+stroke (p=0.006 and p>0.001, respectively). Upon multivariate analysis, mean reticulocyte count was the only significant variable (p=0.0002). We also observed a progressive increase of velocity in the basilar artery of children with higher velocity in the middle cerebral arteries (R= 0.59); p<0.001): 8 out of 25 children with altered TCD had basilar velocity >130 cm/s; out of the 186 low risk children, only one had basilar velocity >130 cm/s (p<0.001). Conclusions: frequency of clinical stroke was similar to that seen in the literature and that of high risk TCD, lower. The accumulated probabilities of altered TCD are high and require special attention in the following of children with SCD. High reticulocyte count was the most important factor in predicting erebrovascular disease. Basilar artery velocity >130 cm/s is another predictive factor for cerebrovascular disease.
As complicações neurológicas na anemia falciforme (AF) são frequentes. Aproximadamente 11% dos pacientes até 20 anos podem ter acidente vascular cerebral (AVC). A realização de Doppler transcraniano (DTC) é importante meio para detecção de risco para AVC isquêmico. O objetivo deste estudo é verificar a incidência de AVC e de DTC alterado em crianças e determinar possíveis fatores de risco. Materiais e Métodos: Foi analisada uma coorte de crianças triadas pelo Programa de Triagem Neonatal de MG, com perfil FS, nascidas de 03/1998 a 12/2005 e acompanhadas no Hemominas de BH até maio de 2009. Para realização do DTC foi feito um corte transversal randomizado de 300 crianças. Os exames foram realizados segundo o protocolo STOP, utilizando-se o DTC pulsado, com sonda de 2 MHz. As crianças com velocidade média máxima (VMM) do fluxo sanguíneo cerebral <170 cm/s nas artérias cerebral média, carótida interna distal e cerebral anterior foram classificadas como de risco baixo; se VMM entre 170-184 cm/s, risco intermediário baixo; se VMM de 185-199 cm/s, risco intermediário alto e se 200 cm/s, risco alto. Resultados: a média de idade foi 6,5 anos (2-11a); 150 meninas. Foram classificadas como de baixo risco 194 crianças (75,6%); 19 risco intermediário baixo (7,4%); 7 risco intermediário alto (2,7%) e 8 risco alto (3,1%); 11,2% dos exames foram inadequados. Sete crianças com risco elevado, após exames confirmatórios, iniciaram regime de transfusão crônica e uma, hidroxiureia. Uma, com baixo risco, desenvolveu AVC hemorrágico (angiografia cerebral normal). Treze crianças (4,8%) haviam sofrido AVC isquêmico antes da realização do DTC. A ocorrência de DTC alterado ou AVC clínico foi observada em crianças com menor média de idade (p=0,002). A probabilidade acumulada de ter AVC até 10 anos de idade foi de 9,5%; a de AVC+DTC alterado (riscos intermediários + alto) de 38,4%. Não houve diferença entre as crianças com DTC normal e as com DTC alterado+AVC, quando se analisaram a antropometria (comparação de médias de escores Z aos 3 anos de idade), ocorrência de sequestro esplênico agudo (p=0,13) e síndrome torácica aguda (p=0,16). As médias de hemoglobina foram inferiores nas crianças com DTC alterado+AVC (p<0,001); as contagens de leucócitos e de reticulócitos foram superiores nas crianças com DTC alterado+AVC (p=0,006 e p<0,001, respectivamente). Em análise multivariada a média de reticulócitos foi a única variável significativa (p=0,0002). Observou-se aumento progressivo da VMM da artéria basilar nas crianças com VMM aumentada nas ACMs (definir a sigla) (R= 0,59; p<0,001): 8 das 25 crianças com DTC alterado possuíam VMM basilar >130 cm/s; entre as 186 com baixo risco, apenas 1 possuía VMM basilar >130 cm/s (p<0,001). Conclusões: a frequência de AVC clínico foi semelhante à da literatura e a de DTC alto risco, inferior. As probabilidades acumuladas de DTC alterado são altas e requerem atenção especial no seguimento de crianças com AF. A contagem elevada de reticulócitos foi o fator mais importante para predizer doença cerebrovascular (DCV). A VMM na artéria basilar >130 cm/s é mais um fator preditivo de DCV.

Durante a Faculdade de Fisioterapia, tive a oportunidade de acompanhar o caso de uma criança com distrofia muscular de Duchenne, época em que fui monitora dos alunos do 8º período no ambulatório de fisioterapia respiratória. Nessa ocasião, intrigou-me o motivo pelo qual não foram abordados pelos professores os aspectos relevantes da avaliação respiratória e o tratamento de pacientes com doenças neuromusculares (DNM). Posteriormente, durante a especialização em fisioterapia respiratória, integrei a equipe de doenças neuromusculares do Hospital das Clínicas da UFMG e, a partir daí, iniciei o acompanhamento de crianças e adolescentes com diferentes diagnósticos de DNM. Pude familiarizar-me com a medida do pico do fluxo da tosse (PFT), ainda pouco utilizada por profissionais da área da saúde. Logo surgiu a necessidade de estudar de forma mais detalhada a literatura disponível sobre o pico do fluxo da tosse e a abordagem pneumológica nesse grupo de doenças, entretanto, algumas dúvidas ainda não conseguiam ser respondidas pelos estudos, tais como: durante a rotina de acompanhamento a essas crianças e adolescentes, quais são os métodos de avaliação respiratória mais indicados? Qual a periodicidade dessas avaliações? Qual a relevância da medida do pico do fluxo da tosse e sua correlação com os parâmetros de avaliação clínico-funcional nesses pacientes? Essas questões, aliadas ao fato de que a cada dia número mais elevado de crianças e adolescentes é referido aos serviços de pneumologia e neurologia pediátrica do Hospital das Clínicas, estimularam o desenvolvimento desta pesquisa. Para tanto, a equipe investiu em equipamentos que possibilitassem a avaliação respiratória das crianças e adolescentes com DNM e, ainda, permitiu o desenvolvimento desta pesquisa com vistas a não somente contribuir para o conhecimento sobre a avaliação respiratória nas DNMs, mas também possibilitar a implementação de acompanhamento pneumológico a esses pacientes com equipamentos específicos e indispensáveis ao propósito. Portanto, o presente estudo tem como objetivo avaliar a correlação do PFT com os parâmetros clínicos e funcionais de crianças e adolescentes com DNM, uma vez que o equipamento no qual se mede o PFT é um instrumento de medida de baixo custo financeiro, portátil e de fácil manuseio. Essas características, aliadas às perspectivas futuras de tratamento dessas doenças, tornam o PFT de importante valor clínico na monitoração de crianças e adolescentes com DNM de forma acessível a toda a equipe multidisciplinar, ao próprio paciente e seus familiares.

The main part of the newborn hearing screening programs is the early diagnosis of hearing problems and the appropriate educational intervention. So that the screening programs can be successful, it is unquestionable the participation of pediatricians, because they have an important role in the parents decisions related to their newborn child. This study aimed to the investigation of the pediatricians knowledge about the correct procedures, the used techniques and the early diagnosis of the hearing problems in newborns, besides identifying the possible factors related to their knowledge about the newborn hearing screening and its interfaces in Childs Health. It is a cross-section study, performed by inquiry of 93 pediatricians associated to the Minas Gerais Pediatrics Association and through questionnaires answered by 34 pediatricians who participated in a congress of pediatric otolaryngology in Minas Gerais. The variables that provided information about the pediatricians profiles were: years of graduation, which college the doctor graduated from, type of specialization, place and year of the conclusion of the residency, type of pos-graduation and year of its conclusion, environment of work and where their knowledge of hearing and its problems were taken. The variables that investigated the doctors knowledge about the hearing screening programs and its interfaces were: the knowledge about which is the best age to perform the screening, the hearing diagnose and the use of the hearing equipments, the knowledge of the risk factors to deafness and the identifications of which children must pass through the program, the methods of evaluation available and the best moment to perform the screening, which conduct is more appropriated in cases of altered screening and normal triage, educational interventions available, justification to perform the early diagnosis and the role of the pediatrician in those cases. It was analyzed as well if the pediatrician had the knowledge of the difference between the deaf children diagnosed and treated precociously and children with normal hearing, the age to initiate the speech pathologist therapy and their interest to obtain more information about the subject and which are the best ways to get that information. According to the results obtained, only 47 (37%) of de pediatricians were considered knower of the subject. 98% demonstrate that they have knowledge about the possibility of evaluating hearing before 30 days of life, but do not know to identify which exams are available to this evaluation, and only 59% of them send all of the newborns to the hearing screening. Most of the pediatrician do not know until which age the diagnosis must be concluded and just a few (8%) know that a baby with less than 30 days can use hearing aids. There were no statistics differences between pediatricians who know the subject and those who don´t related to the average of time of graduation (p=0,52), nature of the institution of graduation (0,06), period of conclusion of the residency (p=0,17), kind of pediatrics specialization (p=0,76), nature of their work environment (p=0,10), knowledge of which age is possible to evaluate the babies hearing (p=0,18) and knowledge that all of the children must pass through the hearing screening process (p=0,07). The other variables researched demonstrate differences statistically significant between knowers and unknowers. The results of this study suggest a real necessity to establish a more effective way to divulgate to the pediatricians the advantages of the newborn hearing screening, the techniques available to its realization and, mainly, which conducts are more appropriate to the after screening steps. There were no specific characteristics found in the pediatricians profiles that could improve the fact of being a knower or unknower of the subject. Information about the importance of the screening to the development of the childs oral language and the necessity that all of the children must pass through the screening; tend to be common knowledge of the pediatricians. The other variables analyzed suggest to change the knowledge of the pediatricians, emphasizing the importance of specific orientations about the theme, due to the fact that most of them (63%) were classified as unknowers of the procedures and conducts involving the screening.
O principal papel dos programas de triagem auditiva neonatal é o diagnóstico precoce dos problemas auditivos e a intervenção educacional adequada e em tempo hábil. Para que os programas de triagem sejam bem sucedidos é indiscutível a necessidade da participação dos médicos pediatras, pois exercem importante papel na tomada de decisões dos pais em relação aos seus filhos recém-nascidos. Este estudo objetivou investigar o conhecimento de pediatras sobre os procedimentos adequados e as técnicas utilizadas para a detecção e o diagnóstico precoce dos problemas auditivos em neonatos além de identificar os possíveis fatores relacionados com o conhecimento deles sobre a triagem auditiva neonatal e suas interfaces na área da saúde da criança. Trata-se de um estudo de corte transversal realizado através de inquérito por meio eletrônico com 93 pediatras associados da Sociedade Mineira de Pediatria e através de questionários respondidos por 34 pediatras participantes de um congresso mineiro de otorrinopediatria. As variáveis que forneciam informações sobre o perfil dos pediatras foram: tempo de formado, faculdade que se graduou, tipo de especialidade, local e ano de conclusão da residência, tipo de pós-graduação e ano de conclusão, local de trabalho e onde adquiriu seus conhecimentos sobre audição e sua deficiência. As variáveis que investigavam o conhecimento médico sobre a triagem auditiva e suas interfaces foram: o conhecimento sobre a melhor idade para realizar a triagem auditiva, o diagnóstico audiológico e o uso do aparelho auditivo. Também investigavam o conhecimento dos fatores de risco para surdez e identificação de quais crianças devem, obrigatoriamente, passar pela triagem, os métodos de avaliação disponíveis e melhor momento para realizar a triagem, qual a conduta mais adequada em casos de triagem alterada e triagem normal, intervenções educacionais disponíveis, justificativa para realizar o diagnóstico precoce e o papel do pediatra nesta atuação. Ainda foi pesquisado, se o pediatra possuía conhecimento da equiparação do desenvolvimento da criança surda diagnosticada e tratada precocemente com a criança normal e idade para iniciar terapia fonoaudiológica e o interesse deles em obter maiores informações sobre o assunto e qual a melhor forma de obter tais informações. De acordo com os resultados obtidos apenas 47(37%) dos pediatras foram considerados conhecedores do assunto. 98% demonstram ter conhecimento sobre a possibilidade de se avaliar a audição antes dos 30 dias de vida, mas não sabem identificar quais os exames disponíveis para esta avaliação e apenas 59% deles encaminham todos os recém-nascidos para a triagem. A maioria dos pediatras desconhece até qual idade o diagnóstico deve preferencialmente ser concluído e poucos (8%) sabem que um bebê com menos de 30 dias pode usar aparelhos auditivos. Não houve diferenças estatísticas entre pediatras conhecedores e não conhecedores quanto à média de tempo de formado (p=0,52), natureza da instituição de graduação (p=0,06), período da conclusão da residência (p=0,17), tipo de especialidade pediátrica (p=0,76), natureza do local de trabalho (p=0,10), conhecimento de qual idade é possível avaliar a audição de bebês (p=0,18) e conhecimento de que todas as crianças devem passar pelo rastreamento auditivo (p=0,07). As demais variáveis pesquisadas demonstraram diferenças estatisticamente significativas entre conhecedores e não conhecedores. Os achados deste estudo sugerem uma real necessidade de se estabelecer uma forma mais efetiva de divulgar para os pediatras as vantagens da triagem auditiva neonatal, as técnicas disponíveis para sua realização e principalmente quais as condutas mais adequadas para as etapas pós-triagem. Não foram encontradas características específicas no perfil dos pediatras que pudessem favorecer o fato de ser conhecedor ou não do assunto. Informações sobre a importância da triagem auditiva para o desenvolvimento da linguagem oral da criança e a necessidade de que todas as crianças devam passar pela triagem tendem a ser de conhecimento geral dos pediatras. As outras variáveis analisadas sugerem influenciar no conhecimento dos pediatras enfatizando a importância de orientações específicas sobre o tema, uma vez que a maioria (63%) foi classificada como não conhecedora dos procedimentos e condutas envolvendo a triagem auditiva.

Annotation:

At the core of any effort by a nation state to regulate new technologies for public release is an implicit navigation of uncertainty. The case of Bt cotton in India presents a very timely and pragmatic example of how nation states grapple with uncertainty in a regulatory context. While much attention has been given to how government actors form regulation, far less is given to how actors outside of the government spheres act as catalysts for regulatory reform. In practice, it is often these parties that drive regulation as a process. The question is how. This paper outlines the findings of fieldwork conducted in India between March 2007 and July 2009 in addressing this central question: what does regulation really mean in a context where new technologies burdened with uncertain consequences are introduced? How do preferences, decisions, and regulatory norms adapt to this introduction based on the interactions of a multitude of parties acting on multiple framings of understanding what risk means? The conclusion is that regulation – in the context of Bt cotton in India - is far from a set of government policies derived from scientific measures of risk assessment. Civil society, firms, and farmers themselves all have tremendous influence on how a nation state navigates uncertainty in a regulatory context. It is a process forged on risk interfaces, where constructions of risk both complement and oppose one another. The actors involved enter these spaces, invited or otherwise. What the government may have initially imagined as ‘regulation' is subject to multiple technical, economic, and political framings of risk from each actor. As a result, regulation is a coevolutionary, co-constructed process. This process of negotiating these spaces is what regulation really means.

In 2003 the United States filed an official complaint against the European Community at the World Trade Organization in regards to the ban imposed on GM crops within the EU, saying that there was no scientific defense for their point of view, and this had created barriers to trade. After one of the longest dispute settlement in WTO history, the body sided with the US and deemed the ban to be restricting free trade. Conflicting research on the safety of GM crops has further complicated the matter and many members of the EU are still choosing to ban GM crops in defiance of the WTO ruling.

Annotation:

Lipopolysaccharides (LPS) are an integral component of the Gram-negative bacterial outer membrane and play an important role in maintaining cellular integrity. L-glyceroD- mannoheptose (Hep) is a primary component of the LPS core region and appears to be synthesised from sedoheptulose-7-phosphate via a four-step process. In Escherichia coli, the final step of Hep synthesis is performed by ADP-L-glycero-D-mannoheptose-6- epimerase, encoded by the gmhD gene. The initial aim of this study was to characterise Hep biosynthesis in Campylobacter jejuni. An E. coli K12 isolate defective in gmhD provided a model with which to study Hep biosynthesis in C. jejuni, in particular the last step in Hep biosynthesis catalysed by the enzyme GmhD. To test whether a functional equivalent of this enzyme is present within Campylobacter, a C. jejuni plasmid expression library was introduced into the E. coli K12 gmhD strain. Restored LPS was assessed by measuring changes in novobiocin sensitivity and LPS profiles of the transformants. Partial nucleotide sequencing of the cloned C. jejuni DNA insert revealed an incomplete ORF that, when translated into amino acid sequence, displayed strong similarity to the 3' end of the GmhD protein from Helicobacter pylori, Aquifex aeolicus, and Haemophilus injluenzae. Transformation of the E. coli K12 gmhD mutant with a plasmid (PDV08) containing a 350 bp in-frame deletion of a C. jejuni gmhD allele failed to restore novobiocin resistance or wild-type LPS expression. Based on this evidence, the gene present in C. jejuni has been named gmhD. Nucleotide sequence analysis indicated that one other gene involved in Hep biosynthesis was likely to be present within this insert (gmhC). Analysis of the assembled gmhD DNA sequence from the C. jejuni genome project revealed an ORF of 954 nucleotides, encoding a protein of 318 amino acids with a calculated mass of 36.0 kDA. Amino acid sequence analysis of the C. jejuni GmhD protein revealed an ADP-binding site as found in the GmhD protein of E. coli, Salmonella typhimurium, and Neisseria gonorrhoeae. Growth of the transformants in minimal and nutrient-rich media revealed reduced growth; however, this might be insignificant. Insertion of a kanamycin resistance cassette into pDV08 followed by gene replacement onto the C. jejuni chromosome by homologous recombination would have completed the construction of a null mutation in gmhD of C. jejuni. However, due to time constraints this was not completed.

Annotation:

The Gaussian Mixture Model (GMM) is among the most widely used parametric probability distributions for representing data. However, it is complicated to analyze the relationship among GMMs since they lie on a high-dimensional manifold. Previous works either perform clustering of GMMs, which learns a limited discrete latent representation, or kernel-based embedding of GMMs, which is not interpretable due to difficulty in computing the inverse mapping. In this paper, we propose Parametric Manifold Learning of GMMs (PML-GMM), which learns a parametric mapping from a low-dimensional latent space to a high-dimensional GMM manifold. Similar to PCA, the proposed mapping is parameterized by the principal axes for the component weights, means, and covariances, which are optimized to minimize the reconstruction loss measured using Kullback-Leibler divergence (KLD). As the KLD between two GMMs is intractable, we approximate the objective function by a variational upper bound, which is optimized by an EM-style algorithm. Moreover, We derive an efficient solver by alternating optimization of subproblems and exploit Monte Carlo sampling to escape from local minima. We demonstrate the effectiveness of PML-GMM through experiments on synthetic, eye-fixation, flow cytometry, and social check-in data.
