Genetic variation lays the foundation for diversity and enables humans to adapt to changing environments. The order of the nucleotides adenine, guanine, cytosine, and thymine on the deoxyribonucleic acid (DNA) molecules of the nuclear chromosomes and mitochondrial DNA (mtDNA) plays an important role in normal cell division, tissue development, and reproduction but is susceptible to alteration from a large number of random, inherited, or environmental events. Variations can range from a change in a single nucleotide to duplication of entire chromosomes...

BACKGROUND: Glucose variations are common throughout sleep and wakefulness in people with type 1 diabetes mellitus (T1DM). The objective of this investigation was to characterize the time-varying coupling between glucose and unstructured physical activity over a 60-hr period in young adults with T1DM. The hypothesis was that coupling would differ during sleep versus wakefulness and would exhibit circadian variations. METHOD: Young adults with T1DM treated with an insulin pump participated in the study...

Preterm birth (PTB, <37 completed weeks' gestation) is one of the leading obstetrical problems in the United States, affecting approximately one of every nine births. Even more concerning are the persistent racial disparities in PTB, with particularly high rates among African Americans. There are several recognized pathophysiologic pathways to PTB, including infection and/or exaggerated systemic or local inflammation. Intrauterine infection is a causal factor linked to PTB thought to result most commonly from inflammatory processes triggered by microbial invasion of bacteria ascending from the vaginal microbiome...

The purpose of this study was to evaluate the effects of a home-based (HB) exercise program on anxiety levels and metabolic functions in patients with anxiety disorders in Taiwan. Purposive sampling was used to recruit 86 participants for this randomized, experimental study. Participants were asked to complete a pretest before the 3-month exercise program, a posttest at 1 week, and a follow-up test at 3 months after the exercise program. Study measures included four Self-Report Scales and biophysical assessments to collect and assess personal data, lifestyle behaviors, anxiety levels, and metabolic control functions...

BACKGROUND: The causes of many cases of preterm birth (PTB) remain enigmatic. Increased understanding of how epigenetic factors are associated with health outcomes has resulted in studies examining DNA methylation (DNAm) as a contributing factor to PTB. However, few studies on PTB and DNAm have included African American women, the group with the highest rate of PTB. METHODS: The objective of this review was to systematically analyze the existing studies on DNAm and PTB among African American women...

BACKGROUND: Fast-track (FT) postoperative protocol in oncological patients after major abdominal surgery reduces complications and length of postoperative stay compared to the conventional (CON) protocol. However, stress and pain responses have not been compared between the two protocols. OBJECTIVES: To compare stress, pain, and related neuropeptidic responses (adrenocorticotropic hormone [ACTH], cortisol, and neuropeptide Y [NPY]) between FT and CON protocols. METHOD: A clinical trial with repeated measurements was conducted (May 2012 to May 2014) with a sample of 63 hepatectomized or pancreatectomized patients randomized into two groups: FT ( n = 29) or CON ( n = 34)...

Patients in intensive care units (ICUs) often experience stress and anxiety. Although stress and anxiety can be pharmacologically attenuated, some drugs cause adverse side effects such as bradycardia, immobility, and delirium. There is thus a need for an alternative treatment with no substantial adverse effects. Music intervention is a potential alternative. In the present study, we used cortisol levels, subjective questionnaires, and physiological parameters to explore the anxiety-reducing effects of music intervention in a sample of ICU patients on mechanical ventilation...

BACKGROUND: Health-care-associated infections (HAIs), infections that patients contract during the course of their hospitalization, are receiving a growing amount of attention. Heavy skin bacterial colonization aids in the transmission and development of HAIs. Nurses frequently use bathing with chlorhexidine gluconate (CHG) to reduce patients' cutaneous microbial burden. This intervention has been shown to have promising but mixed results in the prevention of HAIs. PURPOSE: This article reviews the literature for evidence on the impact of CHG bathing on HAIs...

Since the completion of the Human Genome Project, much has been uncovered about inheritance of various illnesses and disorders. There are two main types of inheritance: Mendelian and non-Mendelian. Mendelian inheritance includes autosomal dominant, autosomal recessive, X-linked, and Y-linked inheritance. Non-Mendelian inheritance includes mitochondrial and multifactorial inheritance. Nurses must understand the types of inheritance in order to identify red flags that may indicate the possibility of a hereditary disorder in a patient or family...

Despite significant advances in cancer treatment and symptom management interventions over the last decade, patients continue to struggle with cancer-related symptoms. Adequate baseline and longitudinal data are crucial for designing interventions to improve patient quality of life and reduce symptom burden; however, recruitment of patients with advanced cancer in longitudinal research is difficult. Our purpose is to describe challenges and solutions to recruitment of patients with advanced cancer in two biobehavioral research studies examining cancer-related symptoms...

INTRODUCTION: Epidural analgesia (EA) is the most widespread pharmacologic method of labor pain relief. There remains disagreement, however, regarding its adverse effects. The objective of this study was to determine the effect of EA administration on the risk of cesarean delivery and its causes (e.g., stalled labor, risk of loss of fetal well-being, among others) and the degree to which this effect may be modulated by mother-, newborn-, and labor-related variables. METHOD: A retrospective cohort observational study was conducted including all deliveries in a Spanish public hospital between March 2010 and March 2013 ( N = 2,450; EA = 562, non-EA = 1,888)...

Although self-efficacy has been used extensively in the field of nursing (e.g., as an outcome measure of nursing interventions), its underlying nature is poorly understood. Investigation of the relationship between self-efficacy and brain activation will help explain the fundamental nature of self-efficacy. In this study, we compared prefrontal activation measured with near-infrared spectroscopy (NIRS) across 89 undergraduate students categorized into three groups based on their General Self-Efficacy Scale scores: low self-efficacy ( n = 59), moderate self-efficacy ( n = 17), and high self-efficacy ( n = 13)...

BACKGROUND: Stress from multiple sources is inherent in law enforcement. However, it is possible to modify responses to stress with resilience training that includes teaching techniques to modify emotional and physical responses to stress, interface with mental health professionals, and practice sessions to improve self-regulation of responses to stress including coherence, a measure of heart rate variability. A gap exists in the research, however, regarding evaluation of the duration of effects after the initial resilience training...
