SUMARY The aim of this study was to evaluate conservation characteristics of sweet sorghum bagasse silages. The experiment was carried out at Fazenda Rio Manso, an experimental unit of the Federal University of the Jequitinhonha and Mucuri Valleys. Twenty-five sorghum cultivars with three replicates were used in a completely randomized design. The juice was extracted from the plant through an electric mill, generating bagasse, which was ground in a stationary silage machine, added of its panicles, and then introduced into experimental silos. Silages of the varieties BR505; CMSXS629; CMSXS635; CMSXS639; CMSXS643; CMSXS646; V82391 and V82392 presented lower rate of total dry matter recovery and, consequently, higher gas losses. The means of dry matter contents of bagasse and silage were 32.80 and 28.55%, respectively. The cultivars BR501; XBSW80147; BR505; CMSXS629; CMSXS633; CMSXS634; CMSXS635; CMSXS639; CMSXS643; CMSXS644; CMSXS648; BRS601; Sugargraze; V82391; V82392 and V82393 showed higher crude protein levels. The cultivar CMSXS642 presented lower neutral and acid detergent fiber content: 39.23 and 19.23%, respectively. The cultivar XBSW80147 showed lower acid detergent fiber content. Means of 3.49 for pH and 0.96 for water activity were recorded. The cultivars BR501 and BRS601 showed higher values of electrical conductivity: 0.93 and 0.95 S/cm, respectively. Higher levels of ammoniacal nitrogen were only observed in cultivars BR501; CMSXS629; CMSXS636; CMSXS648 and V82392. Sorghum bagasse silages presented adequate conservation inside the silos, according to the evaluated variables.

SUMMARY This study analyzed the effect of including copaiba oil as an additive for cattle supplemented on pasture, during the dry season. Four crossbred steers, castrated, with 245 ± 25 kg, aged about 18 months, fitted with permanent rumen cannula; were randomly assigned to a 4×4 Latin square. All animals were housed in individual paddocks (0.3 ha), uniformly covered with Brachiaria brizantha cv Marandu, with through and drinking fountain; and were given a concentrate at 500g/100 kg BW containing 380 g/kg crude protein (%DM). The copaiba oil was added to the supplement as a spray, in the proportions of 0, 0.5; 1.0 and 1.5 g/kg DM intake. Spraying supplementation was performed daily at the time of supply of the supplement. Data of intake and digestibility of nutrients, ruminal pH; ruminal ammonia nitrogen, and microbial protein synthesis were tested by analysis of variance and polynomial regression, adopting a significance level of 5%. The inclusion of copaiba oil quadratically affected total dry matter intake (P=0.030) and CP digestibility (P=0.043), without altering ruminal metabolism (P>0.05) and microbial protein synthesis (P>0.05) of the animals kept on pasture.
Limites para afiliação à vida acadêmica de estudantes de camadas populares no contexto de expansão universitária
Authors: Figueiredo Alice Cristina
Published: July 2018

Resumo Este trabalho objetiva compreender a trajetória acadêmica de estudantes de camadas populares, no curso de engenharia elétrica, criado no contexto de expansão universitária. Em termos teóricos, a pesquisa se apoia nos conceitos de habitus e disposições, nas perspectivas apresentadas por Bourdieu e Lahire; nas noções de integração e afiliação universitária, formuladas, respectivamente, por Tinto e Coulon e nos estudos sobre trajetórias escolares improváveis. Em um total de 99 estudantes, foram identificados nove como pertencentes às camadas populares, dos quais oito participaram da construção dos retratos sociológicos que buscou compreender quais disposições e tipos de comportamentos foram condicionantes para o ingresso e para o processo de integração e afiliação ao ensino superior. A expansão de vagas bem como a reformulação dos processos seletivos para ingresso na instituição são questões estruturais que favoreceram a chegada desses estudantes em um curso considerado de alto prestígio social. Entretanto, a ausência de uma restruturação acadêmica capaz de acolher estudantes de diferentes origens sociais se mostra como fator contrário à democratização real do ensino superior. Além disso, a conclusão da educação básica, embora tenha permitido o acesso ao curso, parece não ter dotado os estudantes de competências, habilidades e conhecimentos necessários à afiliação ao ensino superior. Portanto, questões escolares estruturais, originárias ainda na educação básica, se colocam como um obstáculo para o sucesso universitário. Nesse sentido, a pedagogia racional bem como a pedagogia da afiliação parecem apontar para uma reestruturação universitária, em uma perspectiva inclusiva.
Efeitos longitudinais da socialização política nos comportamentos de participação de jovens
Authors: Rodrigues Mariana , Menezes Isabel , Ferreira Pedro D.
Published: July 2018

Resumo Este artigo parte da premissa de que a socialização política juvenil na contemporaneidade se baseia em processos dinâmicos que emergem da ação e interação simultâneas de diferentes contextos e agentes sociais, constituindo oportunidades de aprendizagem cívica e vivência democrática que influenciam as experiências juvenis de participação cívica e política. Assim, este estudo explora os efeitos longitudinais da interação entre a família, pares, mídia e associação escoteira no ativismo político, participação cívica e participação cívica online de jovens. Recorrendo a um estudo longitudinal de painel, o mesmo coorte de 473 jovens escoteiros(as) portugueses(as), com idades entre os 14 e os 22 anos, foram observados em três momentos separados por seis meses, entre janeiro de 2014 e março de 2015. Uma série de análises de modelos de crescimento latente permitiram analisar os efeitos da combinação dos agentes de socialização política quer nos níveis iniciais quer nas trajetórias de mudança das formas de participação. Os resultados obtidos demonstram não só a interdependência entre os vários agentes de socialização com que os(as) jovens se relacionam no cotidiano, mas também as influências que estes exercem variam consoante o tipo de participação. O ativismo político é influenciado significativamente pelos pares e pela associação escoteira. O desenvolvimento da participação cívica é potenciado pela associação escoteira e pela mídia (televisão e rádio). A participação online é essencialmente fomentada pela mídia (internet, televisão e rádio) e pelas discussões interpessoais sobre assuntos políticos.

Published: July 2018

Resumo Em conforto visual, as pesquisas com crianças têm sido direcionadas ao estudo dos impactos da luz no desempenho acadêmico, e não propriamente na avaliação das preferências, o que evidencia a carência teórica e metodológica nessa linha de estudo. No caso de crianças mais novas, entre 4 e 7 anos de idade, como as habilidades básicas para o intercâmbio verbal estão em desenvolvimento, restringe-se a aplicação de testes escritos. Este artigo, resultado de um trabalho conjunto entre arquitetura e psicologia, apresenta uma abordagem experimental e multimétodos para levantar as preferências do ambiente luminoso, da paisagem e das características de uso de salas de aula de educação infantil. O estudo foi realizado em duas salas de aula do Colégio Logosófico González Pecotche, da cidade de Florianópolis, durante o mês de agosto de 2015. Neste estudo participaram aproximadamente 30 crianças entre 4 e 6 anos de idade. Os resultados obtidos permitem identificar a preferência das crianças por elementos da paisagem natural e por ambientes luminosos mais claros. Foi identificada a relação que as crianças fazem entre as condições de iluminação e as atividades realizadas. Finalmente, a abordagem metodológica se mostra efetiva na aproximação das crianças e na avaliação das preferências com relação ao ambiente luminoso das salas.

Abstract This pilot study aims to analyze the solar radiation transmission, daylight performance and glare reduction probability of complex shape solar control devices, developed with parametric modeling and digital fabrication. As methodology, initially the Rhinoceros3D+Grasshopper digital tools suite was used for the parametric modeling of solar control devices. Performance evaluations were performed by computational simulation and measurements in prototypes. For the simulations, the Diva-for-Rhino and Ladybug plug-ins were used. For the measurements, through digital fabrication, a prototype used for glare evaluations through HDR photographs was made. As main results, the solar control devices contributed to the control of solar radiation admission, better daylight distribution and glare reduction in the indoor analysis environment, confirming the reliability of the methodological procedures employed. It is important to highlight the effects of depth and inclination of the devices analyzed, respectively on the daylight distribution and selectivity in the admission of solar radiation between winter and summer. Finally, the shading masks show that despite all the development of modeling and simulation tools, the simple understanding of the solar geometry is still essential for the adequate performance of the solar control devices.

Authors: Lima Pollyanna Rodrigues , Vergara Erasmo Felipe
Published: July 2018

Resumo Para que o músico desfrute de uma experiência satisfatória no ambiente de sua prática musical, um projeto acústico específico é essencial. Em um contexto em que cada vez mais um mesmo ambiente é utilizado para usos que requerem projetos acústicos distintos, as mesmas salas utilizadas para a palavra falada têm abrigado também a prática musical. O objetivo principal do trabalho foi demonstrar a contribuição da simulação computacional acústica na possibilidade de adaptação de uma sala de aula multiúso existente para o ensino e prática musical. Os principais parâmetros acústicos da sala foram obtidos experimentalmente, e, posteriormente, diferentes alternativas foram testadas fazendo uso da simulação computacional por meio do software Odeon, de forma que se obtivesse um modelo que adequasse a sala à prática musical. Esse modelo passou por diversas adaptações até que resultou em uma sala com valores de parâmetros acústicos dentro dos limites desejáveis, sendo, nas bandas de frequência de oitava de 500 Hz a 1.000 Hz, TR 1,25 s; EDT 1,25 s; C80 1,98 dB; D50 56,1%; e STI 0,56. O modelo computacional resultante permitiu adaptar a sala multiúso, modelada para diferentes realidades, para a prática musical, considerando nesse modelo a inserção ou a remoção de materiais e dispositivos acústicos.

Resumo O objetivo deste trabalho foi aplicar uma metodologia para geração automática de mapas de danos em ortoimagens de fachadas de edifícios, utilizando-se veículo aéreo não tripulado (Vant) para a captura das fotografias. A geração de mapas de danos visa auxiliar na inspeção visual, método empregado nas atividades de recuperação, manutenção ou intervenção em edifícios. Utilizando a técnica de dense stereo matching (DSM), modelos geométricos de edifícios foram gerados por nuvem de pontos no programa PhotoScan para a obtenção de ortoimagens. Após essa etapa, as ortoimagens foram submetidas à etapa de geração de mapas de danos de manchas escuras no Programa Tyche (2015), que mapeou e quantificou percentualmente essas manifestações patológicas. Os resultados dos mapas de danos foram classificados também qualitativamente. A aplicação de Vant demonstrou ser uma ferramenta eficiente para a atividade de inspeção de fachadas e para a captura de imagens a serem utilizadas por meio da técnica DSM. A geração de mapas de danos pelo Tyche (2015) demonstrou ser também eficaz, no entanto a interação do usuário mostrou-se importante para alcançar os resultados esperados.

Published: July 2018

Resumo Durabilidade é a capacidade de a estrutura se manter em condições plenas de utilização, não devendo apresentar danos que comprometam em parte ou totalmente o uso para o qual foi projetada. A construção do Pavilhão de Serviços Gerais 10 (SG-10) foi baseada em paredes de elementos pré-moldados em forma de "U" e cobertura de vigas pré-moldadas e protendidas. Desde o período de sua construção não se tem registro de intervenções que tenham sido realizadas de forma a prolongar sua vida útil. Partindo desse contexto, e sabendo que o conjunto de pavilhões de Serviços Gerais compreende edifícios representativos da Universidade de Brasília, este artigo tem o objetivo de avaliar a condição da estrutura de concreto do SG-10, mapear os níveis de deterioração dos elementos e apresentar propostas de intervenção. Como método de avaliação utilizou-se o Roteiro de Inspeções, que inclui a metodologia GDE/UnB (FONSECA, 2007) como base de quantificação de dano. Após a aplicação da metodologia verificou-se que o edifício do SG-10 precisa passar por um processo imediato de intervenção, sendo necessária a realização de serviços de recuperação da estrutura.

ABSTRACT Objective: To investigate whether the presence of obstructive sleep apnea syndrome (OSAS) alters the perception of respiratory symptoms and quality of life in COPD patients, by using specific questionnaires, as well as to determine whether scales for assessing daytime sleepiness and for screening for OSAS can be used in the triad of OSAS, COPD, and obesity. Methods: We included 66 patients diagnosed with mild-to-moderate or severe COPD and presenting with a body mass index > 27 kg/m2. After polysomnography, patients completed the Epworth sleepiness scale (ESS), the Berlin questionnaire (BQ), the modified Medical Research Council (mMRC) scale, the Baseline Dyspnea Index (BDI), and the Saint George’s Respiratory Questionnaire (SGRQ). Results: Patients were first divided into two groups: COPD + OSAS (n = 46); and COPD-only (n = 20). The COPD + OSAS group was subdivided into a COPD + mild-to-moderate OSAS group (n = 32) and a COPD + severe OSAS group (n = 14), all of which were compared with the COPD-only group. There was a significant difference in mean FEV1 (L) between the COPD + OSAS groups and the COPD-only group (p = 0.073). The presence of the triad did not lead to significantly higher ESS scores, and scores > 10 had a specificity of 0.58. The BQ did not identify high risk for OSAS in the presence of the triad (specificity of 0.31). There were no significant differences in domain or total scores of the SGRQ between the COPD + OSAS groups and the COPD-only group. Conclusions: The confounding factors present in the triad of OSAS, COPD, and obesity prevented the perception of increased daytime sleepiness and high risk for OSAS. We observed no worsening of dyspnea perception or quality of life.

ABSTRACT Objective: To evaluate the relationship between obesity and asthma. Methods: This was a preliminary cross-sectional analysis involving 925 subjects with mild-to-moderate or severe asthma evaluated between 2013 and 2015. Obesity was defined on the basis of body mass index (BMI) and abdominal circumference. We collected clinical, laboratory, and anthropometric parameters, as well as pulmonary function test results and data regarding comorbidities. The subjects also completed asthma control and quality of life questionnaires. Results: Obese individuals had a significantly higher number of neutrophils in peripheral blood than did nonobese individuals (p = 0.01). Among the obese individuals, 163 (61%) had positive skin-prick test results, as did 69% and 71% of the individuals classified as being overweight or normal weight, respectively. Obese individuals showed lower spirometric values than did nonobese individuals, and 32% of the obese individuals had uncontrolled asthma, a significantly higher proportion than that found in the other groups (p = 0.02). Conclusions: Obese individuals with asthma seem to present with poorer asthma control and lower pulmonary function values than do nonobese individuals. The proportion of subjects with nonatopic asthma was higher in the obese group. Our results suggest that obese individuals with asthma show a distinct inflammatory pattern and are more likely to present with difficult-to-control asthma than are nonobese individuals.

Published: July 2018

ABSTRACT International recommendations in spine surgery require reproducible, safe and effective procedures. The placement of pedicle screws is technically demanding and relies on different methods of support, which result a high rate of complications related to suboptimal screw placement, with reports ranging from 15.7% to 40% according to Hansen-Algenstaedt N and Koktekir E in separate studies. This study carried out a systematic review of existing literature to identify the level of evidence of the placement of pedicle screws outside the pedicle in thoracic and lumbar spine. For the systematic review, a search of the existing literature, based on the use of MeSH terms in PubMed-Medline, Ovid, The Cochrane Library, MedicLatina, Elsevier, and EBSCO databases. According to the literature found, most authors agree that the placement of screws outside the pedicle itself does not represent a serious complication or that requires repositioning in a second surgery even when they are found to have a violation up to 50% of the medial wall of the pedicle. However, they agree that repositioning should be immediate if it is shown with imaging studies such as MRI and CT that endangers vascular and/or neurological structures, or are associated with biomechanical alterations of the spine.

ABSTRACT Objective: The objective of this longitudinal retrospective study is to assess the efficacy and safety of total lumbar disc replacement in patients with degenerative discopathy (L3-L4, L4-L5, L5-S1). Methods: One hundred and forty-three patients with low back pain, with or without radiculopathy, who met the radiographic criteria underwent anterior arthroplasty between 2000 and 2016. The Oswestry disability index (ODI), the visual analog scale (VAS), patient satisfaction, success criteria, disc height, and range of motion of the operated segment were evaluated preoperatively and at 3, 6, 12, and 24 months following surgery. Results: There were 50 men and 93 women, with an average age of 39.5 years, 13 patients (9%) with previous discectomy. The arthroplasty was performed at level L5-S1 in 97 patients (67.8%), at level L4-L5 in 45 patients (31.5%), and at level L3-L4 in 1 patient. Between the preoperative period and 24 months following surgery, the ODI decreased by 53.86%, the VAS for low back pain decreased by 63.83%, and low back pain with radiculopathy decreased by 60.20%, all statistically significant (p ≤ 0.5). Eighty-two percent of the patients were completely satisfied and 18% were satisfied. There was an average increase in disc height of 12 mm (p <0.001). The range of motion of the affected segment increased by 4° to 7° after surgery (p <0.004). Conclusions: Lumbar arthroplasty of a segment is recommended as an effective treatment for patients with degenerative disc disease with low back pain with or without a root component who meet the inclusion criteria.

Abstract: It is challenging to reconcile large scale data with the dynamic characteristics present in land use. Such dynamism requires data with a high repetition of sampling. An alternative is the integration of data of high spatial resolution and low temporal resolution, with that of high temporal resolution and low spatial resolution. The aim addressed in this article is related to the integration of aerial photographs and temporal series for land use and land cover mapping in high detail scale. We conducted a case study in Santa Rosa de Lima-SC. The main data used was the aerial survey that overlaid the state of Santa Catarina, executed in 2010/2011. The interpretation key included typical elements of photointerpretation (color, texture, size, shape), aiming to classify the land use and land cover classes. The mapping evaluation resulted in 75.6% global accuracy, ranging from 54% (Grassland and Wetlands) to 96% (Water Bodies and Rocks). Such results are considered satisfactory. The integration of high-resolution images with high temporal resolution data has enabled the discrimination between classes that present great difficulties of separability. Such discrimination is essential in the territorial management processes of Encosta da Serra and the municipality of Santa Rosa de Lima.

Water electrolysis process for hydrogen generation is widely used in various branches of industry. But it has disadvantages like important energy consumption and utilization of separate membranes, which limit the generated gases pressure.
This article describes the hydrogen and oxygen generation technology excluding the separating ion-exchange membranes and providing high gases pressure due to applying the variable valence metal chemically active electrodes as well as due to separating in time and space the electrolytic processes of water decomposition for gases liberation.
The electrolyzer based on this technology surpasses all of the known analogues by the level of technical decisions, simplicity of mounting and servicing, reliability and safety.

Changes in MgH2 decomposition kinetics were investigated in dependence on complex doping of MgH2 by Al, Ti, Ni, and Fe. Reactive mechanochemical alloying method (RMA) was applied in the temperature descending regime. It was found that addition of Al+Ni+Ti, Al+Ti, Fe+Ti (see below) and Al+Fe elements combinations led to a lower thermal stability and, consequently, to a lowering of the temperature of hydrogen desorption onset. Whereas desorption began at temperature of 320 °C from the pure MgH2, the aditions of Al, Ni, Ti and Fe lowered the start of the desorption down to 250°C (at hydrogen pressure 0.1 MPa in the reactor). Very fast desorption kineticsprecize at 300 0C and PH 2= 0.1 MPa were observed for Mg+Me mixture in comparison with the pure Mg. Sorption capacity of investigated mechanically-alloyed composites varied from 5 to 6.5 wt. % H2. The tested materials showed a high potential as hydrogen storage alloys especially for stationary application.

Acetoacetylation of (1,3-dimethylbenzimidazol-2-ylidene)-, (3-methylbenzothiazol-2-ylidene)-, and (3,4-dimethylthiazol-2-ylidene)acetonitriles with 2,2,6-trimethyl-4H-1,3-dioxin-4-one was found to yield appropriate C-acylation products. Treatment of the obtained products with perchloric acid afforded 2-(2-amino-6-methyl-4H-pyran-4-one-3-yl)substituted quaternary azolium salts. Their reduction with sodium borohydride yielded the corresponding dihydro (in the case of benzoazoles) or tetrahydro (in the case of thiazole) derivatives, which were shown to be synthetic equivalents of the title aldehyde.
Archives of Native Presence: Land Tenure Research on the Grand Ronde Reservation
Authors: Kretzler Ian
Published: July 2018

Under the banner of indigenous and collaborative archaeologies, heritage professionals and indigenous peoples have developed new forms of scholarly practice. This work has begun to rectify the discipline's historical marginalization of indigenous groups but remains skewed toward academic projects. Less attention has been paid to the hundreds of Tribal Historic Preservation Offices within tribal nations. This article argues that tribal historic preservation provides needed insight to heritage managers of all stripes. Using the Grand Ronde Land Tenure Project as a case study, I discuss how tribally-driven archival research fosters new accounts of Native history and enhances tribes' capacity to care for cultural resources.

Published: July 2018

The empowerment of women is one of the central issues in the process of development of countries all over the world. The Government of India has made Empowerment of Women as one of the principal objectives of the Ninth Five Year Plan (1997-2002) and also declared 2001 as the year of ‘Women’s Empowerment’. Women's empowerment is a process in which women gain greater share of control over resources - material, human and intellectual like knowledge, information, ideas and financial resources like money - and access to money and control over decision-making in the home, community, society and nation, and to gain `power'. Microfinance is the provision of small amounts of financial services to low income poor and very poor self employed people. The participation of women in Self Help Groups (SHGs) made a significant impact on their empowerment both in social and economical aspects. This study addresses empowerment of Muslim women through microfinance and self help groups in Chennai city of Tamilnadu. The information required for the study has been collected from both the primary and secondary sources. Further statistical analysis has been undertaken using various statistical tools like logistic regression, student t test, F test, Chi square test, ANOVA, Duncan Multiple Range Test (DMRT), the Wald Test, etc.
Notes on Additional Material Associated with the Type Specimens of Diphuicrinus ohioensis (Echinodermata: Crinoidea) from the Middle Pennsylvanian of Southeastern Ohio
Authors: Thomka James R. , Eddy Donald B.
Published: July 2018

The cladid crinoid Diphuicrinus ohioensis Burke, 1976, was originally described from shallow marine facies of the Middle Pennsylvanian Putnam Hill Limestone of southeastern Ohio. One of the type localities for this taxon is an abandoned quarry in Vinton County, where a small number of articulated cups used in erection of this species was collected.  Prior to formal description of this species, multiple isolated calyx ossicles were collected from this locality, but were not analyzed in detail or included in the description of D. ohioensis. The previously unidentified material, described herein, contributes to a more complete record of this taxon.  Further, heavily sculptured (nodose) basal and radial plates are nearly ubiquitously encrusted by calcareous tubes, a paleoecological detail not otherwise noted in the description of D. ohioensis or the lithofacies from which material was collected. Encrusters, which consist of at least 2 varieties, are present primarily in depressed areas in between raised nodes.  This may reflect post-mortem removal via abrading currents but may alternatively represent preferential encrustation of portions of hard bioclasts characterized by larger, smoother, protected surfaces. This study reinforces the value of isolated crinoid ossicles in paleoecology, paleobiology, and paleoenvironmental analysis.
Role of uterine artery Doppler at 12 to 16 weeks of gestation in prediction of pre-eclampsia an observational study
Authors: Neravi Asha , Udayashree Voorkara
Published: July 2018

Background: Pre-eclampsia affects 2-5% of pregnancies and is a major cause of perinatal and maternal morbidity and mortality. Doppler is a non-invasive method for evaluation of feto-placental circulation without affecting pregnancy. A high resistance index in uterine artery Doppler waveform has been shown to be the best non-invasive screening test. Thus, we have conducted this study to find out the predictive value of transvaginal uterine artery doppler in early pregnancy for the prediction of pre-eclampsia. The aim of the study was early prediction of pre-eclampsia by trans-vaginal uterine artery Doppler study at 12-16 weeks.Methods: According to the study criteria 100 antenatal women between 12 to 16 weeks of singleton pregnancy attending out patient in the Department of OBG of S. D. M. Medical College Dharwad were included. After an informed consent, the women underwent ultrasound for dating and subsequently trans-vaginal ultrasound along with color doppler was performed to obtain uterine artery indices. These women were again rescanned at 24-26 weeks of gestation trans-abdominally and further followed up clinically for development of preeclampsia.Results: Out of 100 women, 22 patients developed preeclampsia. At 12-16 weeks 35% of women had bilateral uterine artery notching, mean RI was 0.57 and PI was 0.89. When uterine artery notch at 12-16 weeks alone was considered, 34.28% of women developed preeclampsia. Detection rate increased to 85.71% when RI>0.65 was also included along with notching. Uterine artery notching at 12-16 weeks gestation had 34.29% sensitivity, 84.62% specificity, 70.51% NPV. When notch and RI>0.65 considered together sensitivity and NPV increases to 85.71% to 98.25%.Conclusions: The uterine artery Doppler waveform indices at 12-16 weeks are the best non-invasive screening test available for early prediction of preeclampsia.

Authors: Bhagat Megha , Moitra Bratati
Published: July 2018

Background: Emergency peripartum hysterectomy (EPH) is a rare but a lifesaving procedure done as a last resort to save life of mother. We conducted this study to know the incidence, leading causes, and complications of obstetric hysterectomy.Methods: Authors conducted a retrospective analysis of all the patients who underwent emergency peripartum hysterectomy from January 2015 to December 2017 at RIMS, Ranchi.Results: There were 126 emergency peripartum hysterectomies, with deliveries during the same period being 21732 and the rate of EPH was 5.7 per 1000 deliveries. Most common indication for EPH was uterine rupture (54.6%), followed by uterine atony (18.2%) and morbidly adherent placenta (23.01%). Most of the patients (66.67%) had previous cesarean deliveries. EPH was done following cesarean in 66.67%. Subtotal hysterectomy was done in 88.09%. Intra-operative urinary bladder injury was seen in 11.11% of the patients.Conclusions: Uterine rupture and Morbidly adherent placenta continues to be the most common causes for EPH in our population. Multiparity is an important risk factor among patients with rupture uterus. Cesarean delivery and repeat cesarean deliveries are the likely risk factors for EPH.

Published: July 2018

Background: Cancer cervix is a leading cause of death among women worldwide. Detection of cervical cancer in precancerous stage is 100% curable. Screening with Pap smear has reduced mortality by cervical cancer in developed countries many folds. The objective of the study is to determine prevalence of Cervical Intraepithelial Neoplasia (CIN) in HIV infected women and observe for associated lower genital infections and their correlation with CD4 counts.Methods: The present study is a cross-sectional observational study conducted at PGIMS, Rohtak, Haryana for a period of 18 months. 150 HIV patients and 150 age related control cases were taken. Pap smears were taken and analyzed for cervical abnormalities and genital infections.Results: Of the 300 Pap smear 22 (7.3%) has squamous intraepithelial abnormalities and 278 (92.7%) negative for intra epithelial abnormalities. Prevalence of cervical intraepithelial abnormities among HIV positive 12% while among HIV negative it is 2.7%. Cervical intraepithelial abnormalities were found in 40% and 3.5% of patients with CD4 count <200 and >200 respectively.Conclusions: HIV increases the risk of cervical abnormalities. Frequent screening of these patients for cervical cancer is needed.

Published: July 2018

Background: Puerperal sepsis in developing countries is a major health problem. Antenatal and labour related risk factors play a huge role in causing puerperal sepsis, many of which are modifiable. The aim of the present study is to study the risk factors, clinical features and outcomes of puerperal sepsis in the mother and determine the causative microorganisms involved.Methods: A prospective observational study was conducted at the department of Obstetrics and Gynaecology, Assam Medical college and Hospital from 1st July 2016 to 30th June 2017.Peurperal sepsis cases were identified based on the WHO clinical definition. A total of 88 patients were identified. Information regarding occupation, antenatal care, delivery related events and outcome were recorded on a predesigned proforma. Mothers were followed up till discharge from the hospital.Results: Out of 88 clinically diagnosed patients with puerperal sepsis, common risk factors associated with mortality were young age(p<0.001),primiparity(p 0.005),tea garden workers(p 0.014),few antenatal check-ups and unbooked status (p 0.001) inadequate iron prophylaxis .Among labor related events intrauterine fetal demise (p 0.001), absent membranes on admission (0.001),late presentation (p 0.001) delivery by untrained birth attendant (p <0.001) were significant.24 patients expired due to the disease. Most common isolated in high vaginal swab and blood culture were Klebsiella pneumoniae and CONS respectively.Conclusions: Proper antenatal care and institutional deliveries are the prime and only preventive measure to reduce the burden of puerperal sepsis in our setup.
Study on knowledge and practice regarding no scalpel vasectomy (NSV) among male members of eligible couples in a rural community of West Bengal, India
Authors: Kishore Anand , Pan Tania , Naskar Narendra Nath
Published: July 2018

Background: No Scalpel Vasectomy (NSV) was introduced in India with the aim to increase male participation in family planning methods. But in spite of the best of efforts, it has failed to achieve its goal. The current acceptance of NSV in India has declined from 1 percent (NFHS 3) to 0.3 percent (NFHS 4). This study was done to get an insight regarding knowledge and practice of NSV and elicit the perceived reasons for underutilization of vasectomy in the community.Methods: A community-based cross-sectional study was conducted among 340 male members of eligible couples in six randomly selected villages in Singur from September 2017 to February 2018. Each respondent was interviewed using a structured schedule. All ethical issues were addressed. Data entry and analysis was done using SPSS version 16.0.Results: Out of 340 participants, 57.9% have heard of NSV. Around 61% of the participants have heard of the male contraceptives from media. Although 57.8% knew it to be method of permanent male contraception, only 15.7% were aware that NSV does not need hospitalization. The most frequently reported reasons for underutilization of NSV in the community was fear of surgery (51.3%) and loss of earning due to prolonged bed rest (44.2%). Overall, the proportion of male members of the eligible couples who underwent NSV was 0.6%.Conclusions: Promotional activities should focus on bridging the prevailing information gap regarding NSV among the potential clients. The IEC activities including interpersonal communication and group counselling sessions must deal with their apprehensions thereby changing the behaviour of the society.
