Potenciais tardios no eletrocardiograma de alta resolu o na forma indeterminada da Doen a de Chagas =Late potentials in the signal averaged electrocardiogram in the indeterminate form of Chagas’ Disease
Koehler, Nelson Rudi
Scientia Medica , 2009,
Abstract: Objetivos: avaliar a presen a de potenciais tardios ao eletrocardiograma de alta resolu o (ECGAR) em portadores da forma indeterminada da Doen a de Chagas. Métodos: foi realizado ECGAR em 59 portadores da forma indeterminada da Doen a de Chagas e 44 controles, selecionados na rotina de bancos de sangue. Foi considerado positivo o ECGAR com dois ou três critérios presentes para potenciais tardios. Resultados: entre os controles houve 15 (34,1%) pacientes com ECGAR positivo, enquanto entre os portadores da forma indeterminada da Doen a de Chagas apresentaram-se 13 (22%) com positividade para o exame (p=0,23). Conclus es: entre os portadores da forma indeterminada e os controles negativos para Doen a de Chagas n o houve diferen a significativa na prevalência de potenciais tardios ao ECGAR. Aims: To evaluate the presence of late potentials in the signal-averaged electrocardiogram (SAECG) of patients with the indeterminate form of Chagas’ disease. Methods: Forty four consecutive healthy blood donors and 59 refused candidates to blood donation because of positive tests for Chagas’ disease were submitted to SAECG. Results: Among controls, 15 (34. 1%) had late potentials present, whereas 13 (22. 5%) patients with the indeterminate form of Chagas’ disease had abnormal SAECG (p=0. 23). Conclusions: Blood donors with the indeterminate form of Chagas’ disease do not present late potentials in the SAECG in a proportion significantly different when compared to controls.
Does crossing legs affect the measurement of blood pressure? =Cruzar as pernas influi na medida da press o arterial?
Koehler, Nelson Rudi
Scientia Medica , 2011,
Abstract: Objetivos: comparar as oscila es da press o arterial, com e sem cruzar as pernas. Métodos: oito medidas seriadas de press o arterial, com intervalos de um minuto, foram feitas em cada um de 80 pacientes consecutivos. Na primeira metade dos pacientes (Grupo 1, 40 pacientes), as quatro últimas medi es foram tomadas depois que o paciente cruzou as pernas na altura dos joelhos. Na segunda metade da amostra (Grupo 2, 40 pacientes), todas as oito leituras foram feitas sem cruzar as pernas. para 137,3±24 mmHg após o cruzamento e, no Grupo 2, passou de 132,1±16,2 mmHg nas primeiras quatro medidas para 130,5±16,4 mmHg nas últimas quatro. A varia o no Grupo 1 foi de 4,9 e no Grupo 2 foi de -1,59 (intervalo de 6,5), e esta diferen a foi significativa (p=0,001). A Press o Arterial Diastólica no Grupo 1 variou de 80,9±4 mmHg no pré-cruzamento para 82,3±14 mmHg após o cruzamento das pernas, e no Grupo 2, variou de 79±11 mmHg para 80,1±11 mmHg entre as quatro primeiras e as quatro últimas aferi es. A varia o no Grupo 1 foi de 1,48 e no Grupo 2 foi de 0,79 (intervalo de 0,69), diferen a n o significativa (p=0,59). Conclus es: houve um aumento estatisticamente significativo, mas muito modesto, na Press o Arterial Sistólica entre o pré-cruzamento e o pós-cruzamento das pernas. Na Press o Arterial Diastólica pré e pós-cruzamento de pernas n o houve diferen a significativa. Na prática clínica, a varia o na aferi o de press o arterial, com e sem cruzar as pernas, provavelmente n o tem relevancia clínica, devido à sua pequena magnitude, similar à varia o que ocorre ao acaso.

Petterson, Carlos Henrique Purper;Koehler, Nelson Rudi;Passos, Ronaldo;Christmann, Iuri;
Arquivos Brasileiros de Cardiologia , 1999, DOI: 10.1590/S0066-782X1999000900002
Abstract: objective - to determine if the application of a continuous electrode paste band on precordial leads results in alteration of the electrocardiographic tracing as compared with an adequate amount of electrode paste, and if the former condition does not cause uniform morphologies from v1 to v6. methods - the amplitude and morphology of the electrocardiographic waves on the precordial leads in electrocardiographic tracings, which were performed with standard (control group) or excessive (continuous band) application of the electrode paste, were compared. results - none of the 106 patients studied showed uniformity of the qrs morphology from v1 to v6. the eletrocardiographic alterations identified in the tracings performed with a continuous electrode paste band that showed statistical significance in relation to the control group were the following: inversion of the p wave in v1; inversion of the t wave in v1, v2, and v3; appearance of r' waves in v1 and v2; disappearance of s waves in v1; appearance of s waves in v5 and v6; alterations in the amplitude of almost all waves, in all leads. conclusion - application of a continuous electrode paste band in the precordial leads may cause significant alterations in the electrocardiographic tracing obtained.

Underrepresentation of Women at Academic Excellence and Position of Power: Role of Harassment and Glass Ceiling  [PDF]
Rizwana Yousaf, Rudi Schmiede
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.42023
Abstract: The study intends to comprehend the underrepresentation of women on positions of power and academic excellence in academia. The study explained the role of exploitation and harassment, which might hinder, when women were trying to climb to top hierarchical position. The majority of women supervised by male heads, sexual harassment could be used as a glass ceiling to hamper women to reach top hierarchal level. The majority participants were working on lower academic and administrative hierarchy; they were experiencing harassment throughout the hierarchical level. Similarly, they considered that harassment could contribute to the underrepresentation of women at academic excellence and a position of power.
Harassment Act Implementation in Higher Education Institutions  [PDF]
Rizwana Yousaf, Rudi Schmiede
Open Journal of Leadership (OJL) , 2016, DOI: 10.4236/ojl.2016.51002
Abstract: Effective implementation of harassment Act might be inevitable to acquiring gender equality in higher education institutions and diminishing the influence of patriarchal and conservative mind set. This study intended to explore implementation of the harassment Act (2010) in universities. Although Government of Pakistan has enforced harassment Act and Higher Education Commission (HEC) made it mandatory to implement, none of the university in the sample has implemented it. Various incidence of harassment has been reported by study participants and in certain cases, victims are asked to resign the jobs as they refuse or fail to comply with the drives of male colleagues and heads. Lack of state and organizational control leads women to be silent and tolerant of harassment and ultimately, it encourages perpetrator to continue the derogatory behaviour.
Tuberculosis in complex emergencies
Coninx,Rudi;
Bulletin of the World Health Organization , 2007, DOI: 10.1590/S0042-96862007000800017
Abstract: this paper describes the key factors and remaining challenges for tuberculosis (tb) control programmes in complex emergencies. a complex emergency is "a humanitarian crisis in a country, region or society where there is total or considerable breakdown of authority resulting from internal or external conflict and which requires an international response that goes beyond the mandate or capacity of any single agency and/or the ongoing united nations country programme." some 200 million people are believed to live in countries affected by complex emergencies; almost all of these are developing countries that also bear the main burden of tb. the effects of complex emergencies impact on tb control programmes, interfering with the goals of identifying and curing tb patients and possibly leading to the emergence of mdr-tb. there are many detailed descriptions of aid interventions during complex emergencies; yet tb control programmes are absent from most of these reports. if tb is neglected, it may quickly result in increased morbidity and mortality, as was demonstrated in bosnia and herzegovina and in somalia. tb is a major disease in complex emergencies and requires an appropriate public health response. while there is no manual to cover complex emergencies, the interagency manual for tb control in refugee and displaced populations provides valuable guidance. these programmes contribute to the body of evidence needed to compile such a manual, and should ensure that the experiences of tb control in complex emergencies lead to the establishment of evidence-based programmes.

EDI RUDI
Biodiversitas , 2008,
Abstract: This research was conducted at three sites (Lancang, Pari, and Payung Islands) in the coral reef ecosystem of Kepulauan Seribu, from March 2004 to March 2005 in order to study pattern of coral recruitment. Limestone substrata as collectors were laid for 3 months at 5 and 10 m waters depth at each site, and further were taken and replace with new ones. The result shows that significant recruits number were occurred between locations, number of coral recruits became higher in the direction to the outer part of Kepulauan Seribu. Results also show that coral recruitment at Kepulauan Seribu was occurred year around, but recruits number varied significantly among seasons and waters depth. West season (December 2004-March 2005) and 5 meter waters depth were the highest abundance of coral recruits.
De vraag naar profilering: hulpverlening tussen begrenzing en ontgrenzing
Rudi Roose
Journal of Social Intervention : Theory and Practice , 2008,
Abstract: In the current managerial approach of social work, social work services are expected to strive for a unambiguous identity: social work services must clarify what they do and whom they are doing it with/for. In this article it is argued that this search for a unambiguous identity of social work services is problematic. One of the consequences is the loss of discretion of social workers, who aren’t allowed to work with problems that fall out of range of the identity of the service. The idea is that every unique question needs a unique answer by a unique service. This constricts discretion, which is necessary to meet the complexity of the problems that social work encounters. The search for an unambiguous identity also focuses on a methodological identity rather than a sociopolitical one. The focus on the methodological identity of social work often stresses the individualisation of social problems. Problems such as poverty are seen in terms of problems of exclusion from care rather than exclusion from society. In the article it is argued that the discussion on the identity of social work must broaden its view from the search for a methodological identity towards a search for a socio-political identity: this implies that social work services reflect on broadening rather than limiting their discretion and reflect on the question whether the problems that social work encounters are care problems and/or societal problems.
Two-body polyelectrolyte mediated bridging interactions
Rudi Podgornik
Physics , 2003, DOI: 10.1063/1.1570400
Abstract: We investigate theoretically polyelectrolyte bridging interactions on the two-body level. The model system is composed of two macroions with two oppositely charged flexible chains. The electrostatic interactions are treated on the Debye - H\" uckel level. The formal level of the theory is provided by the Feynman-Kleinert variational method generalized to include also self-interactions between polyelectrolyte segments. The variational equations are shown to exhibit two solution branches corresponding to {\sl strong} and {\sl weak} coupling, whereas conformations of the chain can be described as {\sl weakly} or {\sl strongly paired}. We investigate the effective pair interaction between the macroions in the parameter space and comment on the relevance of the calculation for bridging interactions in experimental context.
