Cationic liposome-nucleic acid (CL-NA) complexes, which form spontaneously, are a highly modular gene delivery system. These complexes can be sterically stabilized via PEGylation [PEG: poly (ethylene glycol)] into nanoparticles (NPs) and targeted to specific tissues and cell types via the conjugation of an affinity ligand. However, there are currently no guidelines on how to effectively navigate the large space of compositional parameters that modulate the specific and nonspecific binding interactions of peptide-targeted NPs with cells...

A variety of terms and measures have been used in the literature to denote being socially integrated, and many studies of older adults focus on only social networks or social support and often only include those living in the community. The purpose of this study was to assess multiple constructs of social integration (i.e., social networks, social capital, social support, and social engagement) for older adults in nursing homes. Data were collected from 140 older adults at 30 nursing homes in Kansas. We interviewed older adults' in-person using a survey questionnaire, and used multilevel confirmatory factor analysis to analyze the data...

This study draws on the emotional cycle of deployment model (Pincus, House, Christenson, & Adler, 2001) to consider how the valence of communication between military personnel and at-home partners during deployment predicts their generalized anxiety upon reunion. Online survey data were collected from 555 military couples (N = 1,110 individuals) once per month for 8 consecutive months beginning at homecoming. Dyadic growth curve modeling results indicated that people's anxiety declined across the transition...

BACKGROUND: Annually, 600 000 deaths are attributed to exposure of non-smokers to secondhand smoke (SHS). These include 165 000 among children, about 60% of which occur in Africa and Southeast Asia. As of 2017, only seven countries in the African region had comprehensive smoke-free legislation covering all public places. Given the increasing prevalence of smoking in many low-income countries, preventing exposure to SHS is an urgent public health priority, particularly in Sub-Saharan Africa...

About 1.4 British million people are at risk of strokes due to non-valvular atrial fibrillation (AF) necessitating long-term anticoagulation. The vitamin K antagonist, warfarin, has a long half-life and narrow therapeutic range necessitating regular monitoring and is a common cause of iatrogenic hospital admission. Direct-acting oral anticoagulants (DOACs), dabigatran, rivaroxaban, apixaban and edoxaban are not required to have monitoring but are sensitive to changes in renal function and are associated with poorer adherence...

Introduction: Ventilation parameter data from patients receiving home mechanical ventilation can be collected via secure data cards and modem technology. This can then be reviewed by clinicians and ventilator prescriptions adjusted. Typically available measures include tidal volume (VT ), leak, respiratory rate, minute ventilation, patient triggered breaths, achieved pressures and patient compliance. This study aimed to assess the potential impact of ventilator data downloads on management of patients requiring home non-invasive ventilation (NIV)...

Research on environmental and genetic pathways to complex traits such as educational attainment (EA) is confounded by uncertainty over whether correlations reflect effects of transmitted parental genes, causal family environments, or some, possibly interactive, mixture of both. Thus, an aggregate of thousands of alleles associated with EA (a polygenic risk score; PRS) may tap parental behaviors and home environments promoting EA in the offspring. New methods for unpicking and determining these causal pathways are required...

The glucocorticoid receptor gene NR3C1 is an important down-regulator of inflammation and is typically under-expressed in individuals with low socioeconomic status (SES). Negative emotionality has been suggested as a potential mediator of SES disparities in health outcomes. In this study, we expand this literature by naturalistically assessing negative emotionality in a key emotional environment: the family. In a sample of 104 youth with asthma (10-17 years) and their primary caregiver, we assessed SES via caregiver report, emotional expression by youth and parents in the home over four days using the electronically activated recorder (EAR), and NR3C1 expression via blood collected from youth...

Falls are the leading cause of fatal and non-fatal injuries among older adults. The American and British Geriatric Societies recommend a fall risk assessment to identify risk factors and guide interventions to prevent these falls. This study describes the self-reported discussion of fall prevention approaches used by primary care providers (PCPs)-family practitioners, internists and nurse practitioners-who treat older adults. Results are described overall and by PCP type. We analyzed a sample of 1210 U.S. PCPs who participated in the 2014 DocStyles survey...

BACKGROUND: Infections cause about one fifth of the estimated 2.7 million annual neonatal deaths worldwide. Population-based data on burden and risk factors of neonatal infections are lacking in developing countries, which are required for the appropriate design of effective preventive and therapeutic interventions in resource-poor settings. METHODS: We used data from a community-based cluster-randomized trial conducted to evaluate the impact of two umbilical cord cleansing regimens with chlorhexidine solution on neonatal mortality and morbidity in a rural area of Sylhet District in Bangladesh...

BACKGROUND: Prolonged immobility in the sitting position in the elderly is known to produce venous stasis with leg edema and possible skin changes. Compression stockings are often applied for this clinical problem. There are few experienced nursing staff available to supervise the difficult task of stocking application. METHODS: The authors have researched other effective and simple devices that may be suitable alternatives. This article reports the results of three different devices to reduce leg edema, as measured by reduction in leg volume : an electro- stimulation device, an adjustable compression Velcro® wrap and a short stretch bandage, each tested over a two-hour period...

BACKGROUND: As information and communication technology is becoming more widely implemented across health care organizations, patient-provider email or asynchronous electronic secure messaging has the potential to support patient-centered communication. Within the medical home model of the Veterans Health Administration (VA), secure messaging is envisioned as a means to enhance access and strengthen the relationships between veterans and their health care team members. However, despite previous studies that have examined the content of electronic messages exchanged between patients and health care providers, less research has focused on the socioemotional aspects of the communication enacted through those messages...

BACKGROUND: Egg allergy is phenotypically heterogeneous. A subset of egg allergic individuals can tolerate egg in an extensively heated form. Inclusion of baked-egg (BE) into their diet accelerates resolution of egg allergy. Conversely, BE reactivity is associated with persistent disease. The immune basis of this clinical heterogeneity is unknown. OBJECTIVES: To study egg-specific antibody, basophil, and T cell responses in children with reactivity or tolerance to BE...

Little research exists on how immigrant children develop their beliefs about school learning (BASLs) in their home and host cultures. We examined the BASLs and achievement children of Chinese immigrants' (CCI) and European American (EA) children. We followed longitudinally 120 middle-class children from age 4 to 5, balanced for gender. Children heard two story beginnings depicting a child eager to attend school and another not. Children completed the stories and were tested for math and literacy achievement...
