Online distance mathematics education in Brazil: research, practice and policy

In this article, we address online distance mathematics education research and practice in Brazil, which are relative newcomers to the educational scene. We present the national context of education in Brazil, highlighting the organization of the educational system, and also a summary of national legislation on distance education and an overview of digital inclusion in the country. We outline the potential and relevance of distance education for the Brazilian educational system and show how it could intervene in the system. With respect to research and practice in online mathematics education, we present support for research, examples of studies and highlight different aspects being addressed, including its essential components. In addition, we discuss the synergy between distance education and teacher education, and mathematics distance education and modeling, as well as other initiatives in the national scenario.

Occlusal trauma can not be compared to orthodontic movement or Occlusal trauma in orthodontic practice and V-shaped recession

The mechanisms of tissue changes induced by occlusal trauma are in no way comparable to orthodontic movement. In both events the primary cause is of a physical nature, but the forces delivered to dental tissues exhibit completely different characteristics in terms of intensity, duration, direction, distribution, frequency and form of uptake by periodontal tissues. Consequently, the tissue effects induced by occlusal trauma are different from orthodontic movement. It can be argued that occlusal trauma generates a pathological tissue injury in an attempt to adapt to new excessive functional demands. Orthodontic movement, in turn,performs physiological periodontal bone remodeling to change the position of the teeth in a well-planned manner, eventually restoring normalcy.

Impact of aerobic exercise capacity and procedure-related factors in lung cancer surgery

Over the past decades, major progress in patient selection, surgical techniques and anaesthetic management have largely contributed to improved outcome in lung cancer surgery. The purpose of this study was to identify predictors of post-operative cardiopulmonary morbidity in patients with a forced expiratory volume in 1 s <80% predicted, who underwent cardiopulmonary exercise testing (CPET). In this observational study, 210 consecutive patients with lung cancer underwent CPET with completed data over a 9-yr period (2001-2009). Cardiopulmonary complications occurred in 46 (22%) patients, including four (1.9%) deaths. On logistic regression analysis, peak oxygen uptake (peak V'(O₂) and anaesthesia duration were independent risk factors of both cardiovascular and pulmonary complications; age and the extent of lung resection were additional predictors of cardiovascular complications, whereas tidal volume during one-lung ventilation was a predictor of pulmonary complications. Compared with patients with peak V'(O₂) >17 mL·kg⁻¹·min⁻¹, those with a peak V'(O₂) <10 mL·kg⁻¹·min⁻¹ had a four-fold higher incidence of cardiac and pulmonary morbidity. Our data support the use of pre-operative CPET and the application of an intra-operative protective ventilation strategy. Further studies should evaluate whether pre-operative physical training can improve post-operative outcome.

Liberal Education, Effective Practice, and Diversity

This session will be based on three presentations that focus on the relationship between liberal education, effective practice and diversity from different perspectives. George Kuh will present data indicating that the educational benefits of "high impact" learning experiences (such as experiential education and undergraduate research), which are significant for all students, are often greater for students from underserved and minority backgrounds than for their majority counterparts. Armando Bengochea will discuss the ways in which an emphasis on effective practice can enhance the educational experiences of students of color within a liberal arts curriculum. Steve Stemler will report on research showing that including practice-oriented criteria in assessments of student achievements and capabilities can assist colleges and universities in identifying and educating minority students with high potential to succeed both in college and beyond college.

Effective Practice and Experiential Education

The central challenge to educators in the liberal arts as in all areas of study is transfer of learning i.e. how can we design learning environments and instruction to that students will be able to use what they learn in appropriate new contexts? Alfred North Whitehead described this as the problem of ‘inert knowledge’ nearly a century ago and Dewey noted that instruction which helps students reproduce what is studied on exams might not produce the depth of understanding that allows for recognizing the relevance of what is known to a particular situation and the ability to apply it. Knowledge that is not conditionalized (i.e. in which the learner does not know when where and why it is to be used) is inert.

[Fixed-combination of losartan/hydrochlorothiazide 100 mg/25 mg. Tolerability and efficacy on blood pressure measured in the practice and for 24 hours]

BACKGROUND: A high proportion of patients with essential hypertension need a combination therapy to reach the therapeutic goal. In the present study, the tolerability and efficacy of a fixed, once daily combination of the AT1 blocker Losartan (100 mg) and the diuretic hydrochlorothiazide (HCTZ) (25 mg) for patients in the real-life situation was investigated. Special consideration was given to the results of ambulatory 24-hourblood pressure (ABP) measurements. METHODS: The open label, prospective non-interventional surveillance study took place from October 2005 to June 2006. A total of 1139 patients over 18 years in age were included whose blood pressures could not be adequately treated with HCTZ alone and for whom an individual dose titration for Losartan and HCTZ had already been performed. RESULTS: The average age (+/- standard deviation) of the patients was 61.2 +/- 11.6 years; 55.8% were men. Comorbidities were common. Specifically, left ventricular hypertrophy was present in 3.1% of the patients, coronary heart disease in 30.1%, chronic heart failure in 11.8% and status post myocardial infarction in 10.5%, respectively. In addition to the Losartan/HCTZ treatment, 61.0% of the patients received a second antihypertensive medicine. After an average treatment duration of 50.4 +/- 17.2 days, the base line systolic blood pressure of 160.8 +/- 16.3 mmHg decreased by 24.0 +/- 17.0 mmHg (-14.4%) and the diastolic blood pressure of 94.4 +/- 9.9 mmHg decreased by 11.8 +/- 10.2 mmHg (-11.8%). For the ABP measurements, the overall average systolic and diastolic blood pressures fell by 16.9 +/- 14.2 mmHg and 8.8 +/-10.3 mmHg, the day average by 17.3 +/- 14.8 mmHg and 9.0 +/- 10.2 mmHg and the night average by 15.1 +/- 17.6 mmHg and 7.8 +/- 11.7 mmHg, respectively. In twelve of the 1139 patients (1.1%), a total of 15 adverse events occurred. A causal connection with the medication was suspected in only in one case (one patient with three). CONCLUSION: The combination of Losartan/HCTZ 100/25 mg, as the exclusive therapy or in addition to other antihypertensive medicines, was for patients, many of whom who had comorbidities, in the real-life situation well tolerated and effective. The efficacy was demonstrated also during the night through ABP.
