Antibody therapeutics offer safe and effective treatment options for a broad range of diseases. One of the greatest benefits of antibody therapeutics is their extraordinarily long serum half-life, allowing infrequent dosing with long-lasting effects. One characteristic of antibodies that drives long half-life is the ability to interact with the recycling receptor, FcRn, in a pH-dependent manner. The benefit of long half-life, however, carries with it liabilities. While the positive effects of antibody therapeutics are long-lasting, any acute adverse events or chronic negative impacts, such as immunosuppression in the face of an infection, are also long-lasting...

Background: Chemotherapy is the backbone of systemic treatment for triple negative breast cancer (TNBC), which is one of the most relevant breast cancers molecular types due to the ability of tumor cells to develop drug resistance, highlighting the urgent need to design newer and safer drug combinations for treatment. In this context, to overcome tumor cell drug resistance, we employed a novel combinatorial treatment including Doxorubicin, Metformin, and Sodium Oxamate (DoxMetOx). Such pharmacological combination targets indispensable hallmarks of cancer-related to aerobic glycolysis and DNA synthesis...

We examined the prevalence and correlates of safer conception methods (SCM) use in HIV-affected couples with fertility intentions. A prospective cohort of 400 HIV clients in Uganda who had fertility intentions with their partner was surveyed every 6 months for 24 months. Logistic regression analysis was used to determine individual, relationship and provider level predictors of SCM use. Over one-third (35%) reported any use of timed unprotected intercourse (TUI) during the study; use of other SCM was rare...

Since the seminal report by the Institute of Medicine, To Err Is Human, was issued in 1999, significant efforts across the health care industry have been launched to improve the safety and quality of patient care. Recent advances in the safety of health care delivery have included commitment to creating high-reliability organizations (HROs) to enhance existing quality improvement activities. This article will explore key elements of the HRO concept of deference to expertise, describe the structural elements that support nurses and other personnel in speaking up, and provide examples of practical, evidence-based tools to help organizations support and encourage all members of the health care team to speak up...

Within sexual partnerships, men make many decisions about sexual behavior, reproductive goals, and HIV prevention. There are increasing calls to involve men in reproductive health and HIV prevention. This paper describes the process of creating and evaluating the acceptability of a safer conception intervention for men living with HIV who want to have children with partners at risk for acquiring HIV in KwaZulu-Natal, South Africa. Based on formative work conducted with men and women living with HIV, their partners, and providers, we developed an intervention based on principles of cognitive-behavioral therapy to support men in the adoption of HIV risk-reduction behaviors such as HIV-serostatus disclosure and uptake of and adherence to antiretroviral therapy...

Many people living with HIV desire childbearing, but low cost safer conception methods (SCM) such as timed unprotected intercourse (TUI) and manual self-insemination (MSI) are rarely used. We examined awareness and attitudes towards SCM, and the correlates of these constructs among 400 HIV clients with fertility intentions in Uganda. Measures included awareness, self-efficacy, and motivation regarding SCM, as well as demographics, health management, partner and provider characteristics. Just over half knew that MSI (53%) and TUI (51%) reduced transmission risk during conception, and 15% knew of sperm washing and pre-exposure prophylaxis...

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is associated with an increased mortality. Knowledge of possible causes of death could lead to an individualization of the palliative treatment concept and result in a differentiated palliative treatment pathway. Currently, only few systematic data are available on the heterogeneity of causes of death associated with ALS. OBJECTIVE: Analysis of the various causes of death in a prospective population-based German cohort of ALS patients...

Alzheimer's disease (AD) is characterized by the presence of parenchymal amyloid-β (Aβ) plaques, cerebral amyloid angiopathy (CAA) and neurofibrillary tangles. Currently there are no effective treatments for AD. Immunotherapeutic approaches under development are hampered by complications related to ineffectual clearance of CAA. Genome-wide association studies have demonstrated the importance of microglia in AD pathogenesis. Microglia are the primary innate immune cells of the brain. Depending on their activation state and environment, microglia can be beneficial or detrimental...

BACKGROUND: Portable intraoperative computed tomography (iCT) with integrated 3D navigation offers new opportunities for more precise navigation in spinal surgery, eliminates radiation exposure for the surgical team and accelerates surgical workflows. We present the concept of "total navigation" using iCT NAV in spinal surgery. Therefore, we propose a step-by-step guideline demonstrating how total navigation can eliminate fluoroscopy with time efficient workflows integrating iCT NAV into daily practice...

The degree of restraint imposed by a psychiatrist seems to be influenced by the safety of the team. So far, there have been few attempts to map the concept of 'feeling safe'.<br/> AIM: To analyse, define and quantify the concept of 'feeling safe'.<br/> METHOD: Concept mapping involves combining, in a structured way, qualitative (item collection) and quantitative methods (multi-dimensional scaling and hierarchical clusteranalysis) with the knowledge of professionals from psychiatric practice (N=24), first on an individual basis and then as a group (N=8)...

OBJECTIVE: Inefficient navigation in electronic health records has been shown to increase users' cognitive load, which may increase potential for errors, reduce efficiency, and increase fatigue. However, navigation has received insufficient recognition and attention in the electronic health record (EHR) literature as an independent construct and contributor to overall usability. Our aims in this literature review were to (1) assess the prevalence of navigation-related topics within the EHR usability and safety research literature, (2) categorize types of navigation actions within the EHR, (3) capture relationships between these navigation actions and usability principles, and (4) collect terms and concepts related to EHR navigation...

Human induced pluripotent stem (hiPS) cell technology has already revolutionized some aspects of fundamental and applied research such as study of disease mechanisms and pharmacology screening. The first clinical trial using hiPS cell-derived cells began in Japan, only 10 years after the publication of the proof-of concept article. In this exciting context, strategies to generate hiPS cells have evolved quickly, tending towards non-invasive protocols to sample somatic cells combined with "safer" reprogramming strategies...

Since the publication of the Institute of Medicine’s report “To Err is Human: Building a Safer Health System” awareness of the importance of medical errors has increased. These are a major cause of morbidity and mortality and recent studies suggest that they can be the third leading cause of death in the United States. Difficulties have been identified by health personnel to prevent, detect and disclose to patients the occurrence of a medical error, an also to report them to the appropriate authorities. Although human error cannot be eliminated, it is possible to design safety systems to mitigate their frequency and consequences...

The promise of drug repurposing is that existing drugs may be used for new disease indications in order to curb the high costs and time for approval. The goal of computational methods for drug repurposing is to enable solutions for safer, cheaper and faster drug discovery. Towards this end, we developed a novel method that integrates genetic and clinical phenotype data from large-scale GWAS and PheWAS studies with detailed drug information on the concept of transitive Drug-Gene-Disease triads. We created "RE:fine Drugs," a freely available, interactive dashboard that automates gene, disease and drug-based searches to identify drug repurposing candidates...

To our knowledge, no study in the United States has qualitatively examined fertility desires, experiences communicating with health care providers about sexual and reproductive health, and attitudes toward reproductive counseling and services in men living with HIV (MLWH) who have sex with women. We conducted focus groups and interviews with MLWH (N = 17) who have sex with women seeking HIV care in San Francisco. The men conveyed limited awareness of safer conception strategies. While many men expressed the desire to have a child, most reported that their providers had not discussed reproduction with them...

Safer conception strategies can prevent HIV transmission between HIV-discordant partners while allowing them to conceive. However, HIV care providers in sub-Saharan Africa report they are not trained in safer conception, and patients are not routinely offered safer conception services. This mixed-methods pilot study evaluated the impact, acceptability, and feasibility of a novel Safer Conception Counseling Toolkit among providers and patients in Kenya. We enrolled 20 HIV-positive women, 10 HIV-discordant couples, and 10 providers from HIV care and treatment clinics...

Providing safe and error-free patient care should resonate well with all healthcare providers including emergency medical technicians. The environments and circumstances in which emergency medical services (EMS) provide patient care inevitably create risks to both the provider and patient. This article explores the concepts of patient safety, errors, near misses, adverse events, and Just Culture. Literature raises concerns about the lack of data collection on both patient and provider safety and research on these safety topics in EMS...
