Article Synopsis
  • The study explores how caregivers of children with cancer in Guatemala City understand illness through Explanatory Models (EMs) during clinical interactions at Unidad Nacional de Oncología Pediátrica (UNOP).
  • It involved analyzing audio recordings and interviews from caregivers to identify how the EM components—cause, occurrence, pathophysiology, course of sickness, and treatment—were discussed in the diagnostic process.
  • The findings revealed that while clinicians often initiated EM discussions, caregivers engaged with most components, particularly focusing on personal illness experiences rather than technical aspects like pathophysiology, highlighting the importance of culturally-competent communication in pediatric oncology care.

Background: Effective communication is founded on bidirectional participation from families and healthcare providers. In adult medicine, bidirectional communication promotes treatment adherence and builds the family-provider relationship. However, the relationship between communication styles in pediatrics remains poorly understood, particularly in culturally diverse settings.

In our daily lives, we are often faced with the need to explain various phenomena, but we do not always select the most accurate explanation. For example, let us consider a "toxic" relationship with physical and psychological abuse, where one of the partners is reluctant to end it. Explanations for this situation can range from emotional or economic dependency to irrational hypotheses such as witchcraft.

In this paper, we propose an application of critical thinking (CT) to real-world problems, taking into account personal well-being (PB) and lifelong formation (FO). First, we raise a substantial problem with CT, which is that causal explanation is of little importance in solving everyday problems. If we care about everyday problems, we must treat the identification of causal relationships as a fundamental mechanism and action as a form of solution once the origin of the problem is unequivocally known.

Critical thinking is a complex reasoning skill, and even though it is hard to reach a consensus on its definition, there is agreement on it being an eminently cognitive skill. It is strongly related with reflective and metacognitive skills, as well as attitudinal or motivational aspects, although no model has yet been able to integrate these three elements. We present herein the preliminary results of a study seeking to establish these relations, in a sample of Chilean university students.

The development of critical thinking in higher education is fundamental, preparing students to think well, find explanations, make decisions and solve problems. Given the importance of its promotion, its assessment is crucial, since the two are inseparable. Moreover, the number of instruments that are validated to assess critical thinking in the Portuguese language and culture are scarce.

Background: In high-income countries, hope facilitates parental coping and builds the clinical relationship between families of children with cancer and their clinicians. However, the manifestation of hope in low- and middle-income countries (LMICs) remains poorly understood. Our study explores Guatemalan parents' experiences with hope during the pediatric oncology diagnostic process and aims to identify discrete actions clinicians take to support hope.

More and more often, we hear that higher education should foment critical thinking. The new skills focus for university teaching grants a central role to critical thinking in new study plans; however, using these skills well requires a certain degree of conscientiousness and its regulation. Metacognition therefore plays a crucial role in developing critical thinking and consists of a person being aware of their own thinking processes in order to improve them for better knowledge acquisition.

Palliative care offers children who have life-limiting and life-threatening oncologic illnesses and their families improved quality of life. In some instances, impeccable symptom control can lead to improved survival. Cultural and financial barriers to palliative care in oncology patients occur in all countries, and those located in Central America are no exception.

Birds have historically suffered adverse effects by toxic elements, such as As, Pb, Hg, and Cd. However, reports on exposure to a wide range of elements, including rare earth elements and other minor elements of emerging concern, and the potential consequences for wildlife are still scarce. This study evaluates blood concentrations of 50 elements and their related effects on lutein and vitamin levels in the Eurasian blackbird () and wild rock pigeon (), inhabiting different scenarios of contaminant exposure.

Current trends in climate change indicate that the impact on the most vulnerable systems will increase. Urban areas, which concentrate population, economic activity and infrastructures, are sometimes at high-risk locations. Yet they are to be considered as vulnerable systems in need of harmonized structures supporting their efforts towards mitigating climate effects and/or adapting their territories to them.

Background: Even within fully integrated health care systems, primary care providers (PCPs) often lack support for medication management. Because challenges with conducting medication reconciliation, improving adherence, and achieving optimal patient outcomes continue to be prevalent nationally, it is critical that PCPs are provided the resources and support they need to provide high-quality, patient-centered care in an accountable care environment.

Program Description: Sharp Rees-Stealy Medical Group uses a fully electronic medication refill system that allows for a centralized team to manage all incoming requests.

Background: Children with cancer in high-income and low-income countries often use traditional complementary/alternative medicine (TCAM). With efforts by the World Health Organization and international twinning programs improving access to conventional care for patients with childhood cancer, understanding the global use of TCAM is important because reliance on TCAM may affect time to presentation, adherence, and abandonment of care. In the current study, the authors describe the process and validation of an international survey documenting the use of TCAM among children with cancer.

Health education is essential not only for preventing illnesses but also for knowing how to act when disease comes. In countries where the education system is inefficient for most of the population and where health issues are often ignored or mistreated because of ignorance or well-intended but ineffective belief in nature's energy and magic, it is important that people have access to truthful information about health issues. Such access allows them to act adequate knowledge and also to learn ways to avoid illness by changing their daily habits into a "healthy way of living.
