Energy is an important concept in all natural sciences, and a challenging one for school science education. Students' conceptual knowledge of energy is often low, and they entertain misconceptions. Educational research in science and mathematics suggests that learning through depictive representations and learning from errors, based on the theory of negative knowledge, can potentially foster students' knowledge of abstract concepts such as energy. Thus, we propose here an instructional approach that combines these two strategies to foster conceptual knowledge of energy...

We assessed the effect of information sources on Ebola-specific knowledge and behavior during the 2014-2015 Ebola virus disease outbreak in Sierra Leone. We pooled data from 4 population-based knowledge, attitude, and practice surveys (August, October, and December 2014 and July 2015), with a total of 10,604 respondents. We created composite variables for exposures (information sources: electronic, print, new media, government, community) and outcomes (knowledge and misconceptions, protective and risk behavior) and tested associations by using logistic regression within multilevel modeling...

Ductal carcinoma in situ (DCIS), the noninvasive form of breast cancer (BC), comprises just over 20% of breast cancer cases diagnosed each year in the USA. Most patients are treated with local excision of the disease followed by whole breast radiation therapy. Total mastectomy is not an uncommon approach, and total mastectomy with a contralateral risk-reducing mastectomy has been on the rise in the past decade. In estrogen receptor-positive disease, patients are often offered endocrine ablative therapy with a selective estrogen receptor modulator or an aromatase inhibitor as both treatment and prevention...

INTRODUCTION: In India and other developing countries, breast conservation surgery (BCS) rates in breast cancer patients are low due to advanced disease at presentation and misconceptions about BCS outcomes. Many patients presenting with large or locally advanced breast cancers (LABC) can be offered post-neoadjuvant chemotherapy (NACT) BCS, safety of which is not as well established as that of primary BCS. This retrospective study compared pathological and surgical outcome parameters in patients undergoing primary and post-NACT BCS...

Fibrosis and remodeling of the right ventricle (RV) are associated with RV dysfunction and mortality of patients with pulmonary hypertension (PH) but it is unknown how much RV fibrosis contributes to RV dysfunction and mortality. RV fibrosis manifests as fibroblast accumulation and collagen deposition which may be excessive. Although extracellular matrix deposition leads to elevated ventricular stiffness, it is not known to which extent it affects RV function. Various animal models of pulmonary hypertension have been established to investigate the role of fibrosis in RV dysfunction and failure...

REVIEW
Yuan Gao, Fangqing Zhao
Recent studies have demonstrated that circular RNAs (circRNAs) are ubiquitous and have diverse functions and mechanisms of biogenesis. In these studies, computational profiling of circRNAs has been prevalently used as an indispensable method to provide high-throughput approaches to detect and analyze circRNAs. However, without an overall understanding of the underlying strategies, these computational methods may not be appropriately selected or used for a specific research purpose, and some misconceptions may result in biases in the analyses...

BACKGROUND: In Peru, despite decades of concerted control efforts, malaria remains a significant public health burden. Peru has recently exhibited a dramatic rise in malaria incidence, impeding South America's progress towards malaria elimination. The Amazon basin, in particular the Loreto region of Peru, has been identified as a target for the implementation of intensified control strategies, aiming for elimination. No research has addressed why vector control strategies in Loreto have had limited impact in the past, despite vector control elsewhere being highly effective in reducing malaria transmission...

Oral diseases, particularly caries and gingivitis, continue to be widespread. Incorporating a stabilized stannous fluoride dentifrice into patients' daily oral hygiene routine is a convenient, cost effective approach to improve and protect their oral health and the appearance of their smile. Unlike other common fluorides that only provide anti-caries benefits (e.g., sodium fluoride and sodium monofluorophosphate), stabilized stannous fluoride formulations have demonstrated broader and significantly greater protection, also reducing plaque, gingivitis, erosion, sensitivity, and halitosis...

This article develops a grounded theory of help-seeking to investigate the social and cultural determinants of help-seeking among Kyrgyz women who have experienced domestic violence. Results indicate that cultural traditions and social norms-most notably the social construction of marriage, the shame associated with divorce, and the status of daughters-in-law in Kyrgyz society-are used to justify domestic violence and prevent victims from seeking help. The proposed theory and results suggest that scholars, policymakers, and front-line contacts must emphasize dispelling myths, misconceptions, and traditional beliefs about gender and marriage to break the abusive dynamics and provide professional help...

Ongoing advancements in neonatal care since the late 1980's have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia (BPD), is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions...

BACKGROUND: Brucellosis is an endemic zoonotic disease in most of the developing world that causes devastating losses to the livestock industry and small-scale livestock holders. Infected animals exhibit clinical signs that are of economic significance to stakeholders and include reduced fertility, abortion, poor weight gain, lost draught power, and a substantial decline in milk production. In humans, brucellosis typically manifests as a variety of non-specific clinical signs. Chronicity and recurring febrile conditions, as well as devastating complications in pregnant women are common sequelae...

Despite the growing elderly population, there is limited research specific to this demographic concerning breast reconstruction (BR). Lack of evidence-based BR recommendations in older populations may contribute to misconceptions and subsequent underutilization of BR, especially autologous BR. Patients who received either deep inferior epigastric perforator (DIEP) flap BR or tissue expander/implant (TE/I) BR by a single surgeon between July 2011 and July 2015 were surveyed postoperatively by using the psychometrically validated BREAST-Q questionnaire to determine patient satisfaction...

Autoantibodies are important indicators for the diagnosis of primary biliary cholangitis (PBC). The autoantibodies in PBC patients are mainly antimitochondrial antibodies (AMAs) and antinuclear antibodies (ANAs). AMAs are one of the diagnostic indices of PBC. PBC-specific ANAs (nuclear dots or nuclear envelope, anti-sp100, and anti-gp210) have a high specificity in the diagnosis of AMA-negative PBC. This article reviews the clinical significance of these autoantibodies and analyzes some misconceptions about the clinical diagnosis of AMA-negative PBC and PBC-AIH overlap syndrome...

Cancer has become a global health concern with marked differences in the incidence and mortality rates between developing and developed countries. Understanding the factors hat shape uptake of preventative and screening services is key. We use in-depth interviews with 13 Zambian urban-based female cancer survivors to explore the facilitators and barriers to screening, diagnosis and treatment, with a particular focus on cultural influences. We identified a central discourse (i.e. a story told about cancer) in all of the interviews: 'cancer is a death sentence'...

The vast majority of women diagnosed with ovarian cancer present with advanced-stage disease with a five-year survival rate less than 50%. Studies have shown that in the past, gynecologic oncologists were not routinely collaborating with palliative care physicians resulting in goals of care planning often not occurring until the last 30 days before death. In recent years, professional societies have been increasingly more vocal about the importance of incorporating palliative care early in a patient's disease course...

BACKGROUND: In children, HIV can be acquired from the mother during pregnancy, delivery and through breast milk. The WHO recommends exclusive breast feeding or exclusive replacement feeding for the first 6 months after birth for HIV-exposed infants. Barriers such as HIV-related stigma, inadequate resources, lack of access to safe water and negative cultural beliefs have been shown to influence infant feeding among HIV-exposed infants in some settings. In Kenya, there is limited literature on the barriers...
