PURPOSE OF REVIEW: There are over 25 million patients living with heart failure globally. Overall, and especially post-discharge, clinical outcomes have remained poor in heart failure despite multiple trials, with both successes and failures over the last two decades. Matching therapies to the right patient population, identifying high-quality sites, and ensuring optimal trial design and execution represent important considerations in the development of novel therapeutics in this space...

PURPOSE OF REVIEW: Mounting evidence supporting the critical contribution of macrophages, in particular osteal macrophages, to bone regeneration is reviewed. We specifically examine the potential role of macrophages in the basic multicellular units coordinating lifelong bone regeneration via remodelling and bone regeneration in response to injury. We review and discuss the distinctions between macrophage and osteoclast contributions to bone homeostasis, particularly the dichotomous role of the colony-stimulating factor 1-colony-stimulating factor 1 receptor axis...

BACKGROUND: Specific mechanisms underlying frailty syndrome are not well known. Frailty can be viewed as a loss of functional reserve resulting in increased vulnerability to stressors. We hypothesize that pathways regulating cellular response to stress are potential players in the development of frailty. The aim of this study was to evaluate the association of the expression of certain genes related to cellular response to stress with the presence of frailty in older patients. METHODS: A sample of 350 individuals aged 65 years or older (22% frail) was selected from the Toledo Study of Healthy Aging...

The epidemic history of Zika virus began in 2007, with its emergence in Yap Island in the western Pacific, followed in 2013-14 by a larger epidemic in French Polynesia, south Pacific, where the first severe complications and non-vector-borne transmission of the virus were reported. Zika virus emerged in Brazil in 2015 and was declared a national public health emergency after local researchers and physicians reported an increase in microcephaly cases. In 2016, WHO declared the recent cluster of microcephaly cases and other neurological disorders reported in Brazil a global public health emergency...

Currently, there is no formal curriculum addressing geriatric oncology within Canadian radiation oncology (RO) residency programs. Knowledge related to geriatric medicine may help radiation oncologists modify RT based on frailty status and geriatric considerations. Understanding specific learning needs allow program coordinators to align the current curriculum with residents' geriatric oncology learning needs. The purpose of this study is to determine the geriatric oncology educational needs of the Canadian RO residents and to inform Canadian RO residency training...

In 2013, the Council for International Organizations of Medical Sciences (CIOMS) created a Working Group on Vaccine Safety (WG) to address unmet needs in the area of vaccine pharmacovigilance. Generating reliable data about specific vaccine safety concerns is becoming a priority due to recent progress in the development and deployment of new vaccines of global importance, as well as novel vaccines targeting diseases specifically endemic to many resource-limited countries (RLCs), e.g. malaria, dengue. The WG created a Guide to Active Vaccine Safety Surveillance (AVSS) to assist national regulatory authorities and national immunization program officers in RLCs in determining the best course of action with regards to non-routine pharmacovigilance activities, when confronted with a launch of a new vaccine or a vaccine that is new to their country...

INTRODUCTION: Despite tremendous growth in the number of health applications (apps), little is known about how well these apps protect their users' health-related data. This gap in knowledge is of particular concern for apps targeting people with dementia, whose cognitive impairment puts them at increased risk of privacy breaches. In this article, we determine how many dementia apps have privacy policies and how well they protect user data. METHODS: Our analysis included all iPhone apps that matched the search terms "medical + dementia" or "health & fitness + dementia" and collected user-generated content...

BACKGROUND: Cervical cancer, nearly all cases of which are caused by one of several high-risk strains of the human papillomavirus (hr-HPV), leads to significant morbidity and mortality in individuals with a cervix. Trans masculine (TM) individuals were born with female reproductive organs and identify as male, man, transgender man, or another diverse gender identity different from their female assigned sex at birth. Routine preventive sexual health screening of TM patients is recommended, including screening for cervical cancer and other sexually transmitted infections (STIs); however, as many as one in three TM patients are not up-to-date per recommended U...

Artemisinin and its derivatives (collectively termed as artemisinins) are among the most important and effective antimalarial drugs, with proven safety and efficacy in clinical use. Beyond their antimalarial effects, artemisinins have also been shown to possess selective anticancer properties, demonstrating cytotoxic effects against a wide range of cancer types both in vitro and in vivo. These effects appear to be mediated by artemisinin-induced changes in multiple signaling pathways, interfering simultaneously with multiple hallmarks of cancer...

Population-based cancer screening for cervical, breast, and colorectal cancers improves patient outcomes, yet screening rates remain low for some cancers. Despite studies investigating physician perceptions and practices for screening, many have focused on individual cancers and lack primary care physicians' (PCPs) realities around screening for multiple cancers. We surveyed 887 PCPs in British Columbia (BC) to examine practices, beliefs, barriers, and learning needs towards cancer screening across breast, cervical, colorectal, prostate, as well as hereditary predisposition to cancer...

Myelodysplastic syndromes/myeloproliferative neoplasms (MDS/MPN) are aggressive myeloid malignancies recognized as a distinct category owing to their unique combination of dysplastic and proliferative features. Although current classification schemes still emphasize morphology and exclusionary criteria, disease-defining somatic mutations and/or germline predisposition alleles are increasingly incorporated into diagnostic algorithms. The developing picture suggests that phenotypes are driven mostly by epigenetic mechanisms that reflect a complex interplay between genotype, physiological processes such as ageing and interactions between malignant haematopoietic cells and the stromal microenvironment of the bone marrow...

Hearing loss is the most common sensorineural disorder worldwide and is associated with more than 1000 mutations in more than 90 genes. While mutations in genes such as GJB2 (gap-junction protein β 2) and GJB6 (gap-junction protein β 6) are highly prevalent in Caucasian, Asian, and Middle Eastern populations, they are rare in both native African populations and those of African descent. The objective of this paper is to review the current knowledge regarding the epidemiology and genetics of hearing loss in African populations with a focus on native sub-Saharan African populations...

Connexin 43 (Cx43) forms gap junction channels that are essential for the propagation of electrical depolarization in cardiomyocytes, but also with important roles in the pathophysiology of reperfusion injury. However, more recent studies have shown that Cx43 has also important functions independent from intercellular communication between adjacent cardiomyocytes. Some of these actions have been related to the presence of Cx43 in the mitochondria of these cells (mitoCx43). The functions of mitoCx43 have not been completely elucidated, but there is strong evidence indicating that mitoCx43 modulates mitochondrial respiration at respiratory complex I, production of radical oxygen species and ATP synthesis...

PURPOSE: Accurate knowledge of the vital status of individuals is critical to the validity of mortality research. National Death Index (NDI) and NDI-Plus are comprehensive epidemiological resources for mortality ascertainment and cause of death data that require additional user validation. Currently, there is a gap in methods to guide validation of NDI search results rendered for active duty service members. The purpose of this research was to adapt and evaluate the CDC National Program of Cancer Registries (NPCR) algorithm for mortality ascertainment in a large military cohort...

Based on psychological autopsy data, the study compared awareness of suicide risk in the deceased among next-of-kin (NOK) and health care professionals (HCPs), and communication between these two groups in the month before death. The NOKs had significantly more knowledge about the decedent's suicide warning signs than the HCPs (90.5% vs. 44.6%). Contact between NOK and HCP was initiated more often by the family than the HCPs (29.4% vs. 5.9%). The study found communication gaps between HCPs and NOK and stresses the need for suicide prevention strategies strengthening communication between these two groups...
