ASSESSING MUSCULAR FATIGUE VIA SURFACE ELEC-TROMYOGRAPHY DURING DYNAMIC KNEE EXTENSIONS 

Exercise to fatigue at different loads has been reported to elicit similar gains in strength and hypertrophy if exercise is taken to momentary muscle failure (MMF). The proposed mechanism is speculated to be due to variation in the activation patterns of the muscles involved. PURPOSE: To examine the effect of exercise at two different loads through surface electromyography (sEMG). METHODS: Thirty participants (Age = 21.7 ± 3.4 yrs; Height = 170.5 ± 8.3 cm; Body Mass = 69.9 ± 14.8 kg) conducted an initial 1-repetition maximum (1-RM) testing session followed by exercise to MMF in two separate sessions set at least 48 hours apart in a random order. Surface electromyography signals were collected during dynamic knee extensions to fatigue at a load of 40% and 70% 1-RM, respectively, from the vastus medialis of both the dominant and non-dominant leg. For both conditions, random intercept and slope models were the best fitting. RESULTS: There were significant linear increases in amplitude with an increase in repetitions for both conditions. The slope for the 70% 1-RM conditions was greater than the 40% 1-RM condition. CONCLUSIONS: These results suggest that the amplitude varies directly with number of repetitions completed and at the 70%1-RM condition the amplitude increases were greater.

TATTOOS AND SELF HARM IN YOUNG ADULTS: ARTISTIC EXPRESSION OR EMOTIONAL REGULATION? 

Study findings have shown both common characteristics and differences between individuals who have a history of self-harm and those who engage in tattooing. Still, these commonalities and differences are not well-understood. The purpose of this study was to examine the relationships between a history of self-harm, acquisition of tattoos, and emotional regulation strategies in young adults between the ages of 18 and 25. The research questions guiding this work included: Is there a relationship be-tween engaging in self-harm and obtaining tattoos? And, what relation-ships might exist between engaging in self-harm, obtaining tattoos, and emotional regulation strategies (interpersonal strategies vs. intrapersonal strategies). Data were collected using Qualtrics, an online survey tool, in which the following measures were used: The Emotional Regulation Questionnaire (ERQ) (Gross & John, 2003), the Deliberate Self-Harm Inventory (DSHI) (Gratz, 2001), the Interpersonal Emotional Regulation Questionnaire (IERQ) (Hoffman, Carpenter & Curtis, 2016), and a tattoo acquisition questionnaire. The survey link to these measures was posted on social media (Facebook and Twitter), was sent through mass email within the university, and was listed on recruitment flyers posted throughout the UNCW campus. This study was approved by the UNCW Institutional Review Board (IRB). The data were analyzed using SAS statistical software. Results revealed that participants who engaged in self-harm activity did in fact obtain more tattoos than those who have not self-harmed. From this study will help health professionals, including nurses, better understand the motives related to self-harm and tattooing behaviors. The knowledge gained can be used to enhance ways that health professionals assess, communicate, and care for this population.

BARRIERS TO PARTICIPATION IN PREGNANCY EXPOSURE REGISTRIES AMONG NURSES AND NURSE PRACTITIONERS 

Objective: To evaluate the level of awareness concerning pregnancy registries and characterize reporting patterns and willingness to participate among nurses and nurse practitioners (NPs). Methods: An IRB-approved cross-sectional survey was distributed to an international volunteer sample of nurses and NPs (males and females, 18 years of age) as an anonymous online survey. Results: Study participants (n=221) included 199 nurses (99.1%) and 22 NPs (9.9%) from a variety of therapeutic specialties and clinical practices located in 7 countries and 17 U.S. states and territories. Only 2 (1%) participants had reportedly enrolled a patient in a pregnancy registry, and 1 (0.5%) reported having been contacted by a pregnancy registry for patient follow-up information. Conclusions: This study suggests most nurses and NPs do not report patient data to pregnancy registries primarily due to lack of knowledge or unfamiliarity with reporting processes. Increased awareness among nurses and NPs about pregnancy registries is needed.
