Does Aerobic Exercise Increase 24-Hour Ambulatory Blood Pressure Among Workers With High Occupational Physical Activity?-A RCT.

ObjectiveHigh occupational physical activity (OPA) increases cardiovascular risk and aerobic exercise has been recommended for reducing this risk. This paper investigates the effects of an aerobic exercise intervention on 24-hour ambulatory blood pressure (ABP) among cleaners with high OPA.MethodsHundred and sixteen cleaners between 18 and 65 years were randomized. During the 4-month intervention period, the aerobic exercise group (AE) (n = 57) performed worksite aerobic exercise (2 × 30 minutes/week), while the reference group (REF) (n = 59) attended lectures. Between-group differences in 4-month ABP changes were evaluated by intention-to-treat analysis using a repeated-measure 2 × 2 multiadjusted mixed-models design.ResultsRelative to REF, 24-hour ABP significantly increased in AE: systolic 3.6 mm Hg (95% confidence interval (CI) 1.6-5.7) and diastolic 2.3 mm Hg (95% CI 0.9-3.8). Cleaners with high aerobic workload exhibited particularly high 24-hour ABP increases: systolic 6.0 mm Hg (95% CI 2.4-9.6), and diastolic 3.8 mm Hg (95% CI 1.3-6.4).ConclusionAerobic exercise increased 24-hour ABP among cleaners. This adverse effect raises questions about the safety and intended benefits of aerobic exercise, especially among workers with high OPA and a demanding aerobic workload. http://www.controlled-trials.com/ISRCTN86682076.

An account of second language teaching and learning in a multi-standard farm school classroom, utilising an ethnographic approach

Multi-standard classrooms are a distinctive feature of many South African farm schools. This study adopts an ethnographic approach in order to explore how classroom life in one particular Eastern Cape multistandard farm school classroom is shaped by a set of circumstances which influence the nature of teaching and learning in that classroom. The research focuses on the extent to which the difficulties associated with teaching a multi-standard class dictate the teacher's approach to lesson planning and style of teaching and how the resultant pattern of interaction influences language learning within a second language context. Data from a variety of sources, obtained primarily through classroom observations, interviews and questionnaires, is presented. Findings tend to indicate that the demands made on the teachers and pupils in terms of large, multi-standard classes, second language medium of instruction and lack of teaching aids, encourages the use of rote learning techniques which are not conducive to language learning. The pattern of interaction that predominates is a teacher-led series of questions and prompts followed by a chorus response from the pupils. This pattern tends to undermine the communicative aspects of language learning by reducing natural interaction and results in pupil passivity as language learners

A Escola Luterana e o rito da confirmação: descontinuidade da escolarização na Serra do Tapes/RS (1938-1971)

O trabalho tem como objetivo discutir aspectos da escolarização luterana e o rito da confirmação em comunidades étnicas pomeranas da Serra dos Tapes/RS. Pretende-se evidenciar os impactos desse rito na descontinuidade dos estudos de crianças e jovens escolarizados entre o período de 1938 a 1971. Tal interrupção dos estudos esteve ligada ao seguimento do trabalho agrícola nas propriedades rurais dessas famílias pomeranas. Esse grupo teve, ao longo dos anos, dedicação predominante à agricultura, por isso usavam a confirmação como uma justificativa da igreja para que os filhos saíssem da escola. Concluiu-se que a liberdade de escolhas adquirida com a confirmação, a não presença de escolas de ensino secundário nessas zonas rurais, e a legitimação da profissão agrícola dentro do contexto cultural, foram fatores que associados geraram uma descontinuidade nos estudos desse grupo étnico, favorecendo uma baixa escolaridade e uma perpetuação histórica da agricultura e permanência dos pomeranos no meio rural

Escolas particulares luteranas da Serra dos Tapes – RS (1938 – 1971): aspectos de uma cultura material

O presente artigo traz como temática a cultura material escolar de quatro instituições educacionais luteranas da região geográfica da Serra dos Tapes, no sul do estado do Rio Grande do Sul, entre os anos de 1938 a 1971. O objetivo central deste escrito é discutir as características da cultura escolar destas escolas que possuíam características singulares, pois oriundas de um processo histórico de colonização alemã e pomerana, tiveram a intervenção patriótica da nacionalização do ensino, e carregavam as marcas da etnicidade do grupo étnico que as frequentava. A metodologia de pesquisa conta com o uso da história oral e análise documental. Ao longo do estudo percebeu-se que a cultura escolar dessas instituições é específica, com classes multisseriadas que valorizavam o ensino da religião, da matemática, da leitura, da escrita e orientações cívicas, visando uma formação básica para que o aluno atuasse como agricultor camponês com sua família

Mosque-based emotional support among young Muslim Americans

Despite a growing literature on social support networks in religious settings (i.e., church-based social support), little is known about mosque-based support among Muslims. This study investigates the demographic and religious behavior correlates of mosque-based social support among a multi-racial and ethnic sample of 231 young Muslims from southeast Michigan. Several dimensions of mosque-based support are examined including receiving emotional support, giving emotional support, anticipated emotional support and negative interactions with members of one’s mosque. Results indicated that women both received and antic- ipated receiving greater support than did men. Higher educational attainment was associated with receiving and giving less support compared to those with the lowest level of educational attainment. Moreover, highly educated members reported fewer negative interactions than less educated members. Mosque attendance and level of congregational involvement positively predicted receiving, giving, and anticipated emotional support from congregants, but was unrelated to negative interactions. Overall, the study results converge with previously established correlates of church- based emotional support.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107410/1/art%3A10.1007%2Fs13644-013-0119-0(1).pd

Extensive myiasis infestation over a squamous cell carcinoma in the face : case report

Human myiasis is a parasitosis found in tropical and underdeveloped countries. It usually affects the elderly, unhealthy and mentally disabled individuals. It is caused by dipterous that lay their eggs in necrotic or infected tissues, although areas of the body that are apparently healthy can also be affected. Frequently the fly deposits several eggs on the peripheral parts of scratches and wounds. The treatment of myiasis involves mechanical removal of the larvae with hemostatic pincers. Larvae rupture must be avoided. Application of topical ether or similar volatile substance is useful. Preventive approach measures, including basic health care, hygiene, access to primary health service, and safe water and drainage, are fundamental to prevent human myiasis. The authors present a case report of myiasis infestation over an extensive head and neck squamous cell carcinoma from a 72-year-old patient living in a rural area. Approximately 200 larvae were removed and the patient was taken to the hospital?s head and neck surgery service
