REVIEW
Cristiana Paul, David M Brady
CONTEXT: Three natural forms of vitamin B12 are commercially available: methylcobalamin (MeCbl), adenosylcobalamin (AdCbl), and hydroxycobalamin (OHCbl), all of which have been shown in clinical studies to improve vitamin B12 status. They are bioidentical to the B12 forms occurring in human physiology and animal foods. In contrast, cyanocobalamin (CNCbl), a synthetic B12 compound used for food fortification and in some supplements, occurs only in trace amounts in human tissues as a result of cyanide intake from smoking or other sources...

Sander Greenland
I present an overview of two methods controversies that are central to analysis and inference: That surrounding causal modeling as reflected in the "causal inference" movement, and that surrounding null bias in statistical methods as applied to causal questions. Human factors have expanded what might otherwise have been narrow technical discussions into broad philosophical debates. There seem to be misconceptions about the requirements and capabilities of formal methods, especially in notions that certain assumptions or models (such as potential-outcome models) are necessary or sufficient for valid inference...

Pediatric occupational therapy practitioners frequently provide interventions for children with differences in sensory processing and integration. Confusion exists regarding how best to intervene with these children and about how to describe and document methods. Some practitioners hold the misconception that Ayres Sensory Integration intervention is the only approach that can and should be used with this population. The issue is that occupational therapy practitioners must treat the whole client in varied environments; to do so effectively, multiple approaches to intervention often are required...

BACKGROUND: The United Kingdom's National Institute for Health and Care Excellence (NICE) recently published recommendations that support planned home birth for low-risk women. The American College of Obstetricians and Gynecologists (ACOG) remains wary of planned home birth, asserting that hospitals and birthing centers are the safest birth settings. Our objective was to examine opinions of obstetricians in Salt Lake City, Utah about home birth in the context of rising home birth rates and conflicting guidelines...

BACKGROUND: Advances in genetic and genomic research have introduced challenges in obtaining informed consent for research in low and middle-income settings. However, there are only few studies that have explored challenges in obtaining informed consent in genetic and genomic research in Africa and none in South Africa. To start filling this gap, we conducted an empirical study to investigate the efficacy of informed consent procedures for an H3Africa genomic study on Rheumatic Heart Disease (RHDGen) at the University of Cape Town in South Africa...

For many women experiencing motherhood for the first time, the message they receive is clear: mothers who do not breastfeed ought to have good reasons not to; bottle feeding by choice is a failure of maternal duty. We argue that this pressure to breastfeed arises in part from two misconceptions about maternal duty: confusion about the scope of the duty to benefit and conflation between moral reasons and duties. While mothers have a general duty to benefit, we argue that this does not imply a duty to carry out any particular beneficent act...

BACKGROUND: Advocacy for male involvement in family planning has been championed over the years after the 1994 International Conference on Population and Development (ICPD). There are a few contraceptive methods for men, and vasectomy uptake has been identified as one of the indicators of male involvement in family planning. Vasectomy also known as male sterilization is a permanent form of contraception. It is a generally safe, quick, easy, effective surgical operation with rare complications to prevent release of sperm...

BACKGROUND: Safe management of faeces (SMoF) and environmental contamination by faecal pathogens have been extensively researched although the SMoF in under-five children has been perennially neglected perhaps due to the misconception that it is harmless. This research, therefore, studied the situation, to determine the magnitude and dimensions of the problem aimed at making policy level stakeholders aware of child faeces management systems and so, inform evidence-based implementation of child and health-related programmes in Nigeria...

Luminescence quenching at high dopant concentrations generally limits the dopant concentration to less than 1-5 mol% in lanthanide-doped materials, and this remains a major obstacle in designing materials with enhanced efficiency/brightness. In this work, we provide direct evidence that the major quenching process at high dopant concentrations is the energy migration to the surface (i.e. surface quenching) as opposed to the common misconception of cross-relaxation between dopant ions. We show that after an inert epitaxial shell growth, erbium (Er3+) concentrations as high as 100 mol% in NaY(Er)F4/NaLuF4 core/shell nanocrystals enhance the emission intensity of both upconversion and downshifted luminescence across different excitation wavelengths (980, 800, and 658 nm), with negligible concentration quenching effects...

REVIEW

Adjuvant treatment options for Stage I seminoma include active surveillance, chemotherapy, and radiotherapy. Active surveillance may not be ideal for the average Indian patient. Of the two accepted adjuvant therapy options, namely single-dose carboplatin chemotherapy and radiotherapy to the retroperitoneal nodes, though it intuitively appears more appealing, a deeper review reveals the potential drawbacks of chemotherapy. This article highlights the misconceptions regarding carboplatin and provides reasons for an argument why radiotherapy is better when a patient with Stage I seminoma chooses to undergo adjuvant treatment...

Contaminated hands can play pivotal role in the development and spread of healthcare-associated infections. Consequently hand hygiene practice performed with adequate technique and with adequate timing is an essential implement for patient safety. Inhibition of the practice of high level hand hygiene by the misconceptions or deficient knowledge of healthcare workers may lead to negative influence on the quality of patient care. Erroneous beliefs or "rumourous knowledge" acquired from colleagues can not only influence the attitude of healthcare workers, but can also give rise to insufficient hand hygiene compliance...

Antibiotics over-consumption is a pandemic that has a tremendous cost on the overwhelmed healthcare system. The accessibility of antibiotics coupled with the misconception of public toward those drugs both of which implicated in the use and misuse of antibiotics. The aim of this study was to investigate the perception of the community toward antibiotics, its purpose and harmfulness, in addition to the accessibility of those drugs as over the counter and without prescriptions. We also investigated the behavior toward antibiotic prescriptions when perceived unnecessary...

Palliative care provides invaluable clinical management and support for patients and their families. For most people, palliative care is not provided by hospice and palliative medicine specialists, but rather by their primary care providers. The recognition of hospice and palliative medicine as its own medical subspecialty in 2006 highlighted the importance of palliative care to the practice of medicine, yet many health care professionals harbor misconceptions about palliative care, which may be a barrier to ensuring that the palliative care needs of their patients are identified and met in a timely fashion...

Gerassimos J Mantzaris
Although we have been living in the era of biologic therapy for several decades, the use of immunomodulators (primarily thiopurines [azathioprine and mercaptopurine] and less so methotrexate) still remains an important component of the inflammatory bowel disease (IBD) pharmaceutical arsenal. Thiopurines as monotherapy exert corticosteroid-sparing effects and can maintain long-term remission in a considerable proportion of patients who have frequent relapses and are or have become mesalazine and/or corticosteroid intolerant or refractory...
