Multi-Ingredient Preworkout Supplementation Compared With Caffeine and a Placebo Does Not Improve Repetitions to Failure in Resistance-Trained Women.

There has been an increase in the use of commercially available multi-ingredient preworkout supplements (MIPS); however, there are inconsistencies regarding the efficacy of MIPS in resistance-trained women. PURPOSE: To determine the effect of varying doses of MIPS compared with caffeine only (C) and a placebo (PL) on resistance-training performance in trained women. METHODS: Ten women (21.5 [2.3] y) completed 1-repetition-maximum tests at baseline for leg press and bench press. A within-group, double-blind, and randomized design was used to assign supplement drinks (ie, PL, C, MIPS half scoop [MIPS-H], and MIPS full scoop [MIPS-F]). Repetitions to failure were assessed at 75% and 80% to 85% of 1-repetition maximum for bench and leg press, respectively. Total performance volume was calculated as load × sets × repetitions for each session. Data were analyzed using a 1-way repeated-measures analysis of variance and reported as means and SDs. RESULTS: There were no differences in repetitions to failure for bench press (PL: 14.4 [3.2] repetitions, C: 14.4 [2.9] repetitions, MIPS-H: 14.2 [2.6] repetitions, MIPS-F: 15.1 [3.1] repetitions; P = .54) or leg press (PL: 13.9 [7.8] repetitions, C: 10.8 [5.9] repetitions, MIPS-H: 13.1 [7.1] repetitions, MIPS-F: 12.4 [10.7] repetitions; P = .44). Furthermore, there were no differences in total performance volume across supplements for bench press (PL: 911.2 [212.8] kg, C: 910.7 [205.5] kg, MIPS-H: 913.6 [249.3] kg, MIPS-F: 951.6 [289.6] kg; P = .39) or leg press (PL: 4318.4 [1633.6] kg, C: 3730.0 [1032.5] kg, MIPS-H: 4223.0 [1630.0] kg, MIPS-F: 4085.5 [2098.3] kg; P = .34). CONCLUSIONS: Overall, our findings suggest that caffeine and MIPS do not provide ergogenic benefits for resistance-trained women in delaying muscular failure.

Decision support for the triage of lung transplant recipients on the basis of home-monitoring spirometry and symptom reporting.

Purpose The objective of this study was to develop and evaluate a computerized rule-based decision support algorithm for nursing triage of potential acute bronchopulmonary events in lung transplant recipients on the basis of home monitoring of spirometry and symptoms. Methods The algorithm automatically separates recipients into 2 groups: those who are stable or improving and those who should be "watched" further because of their potential for developing bronchopulmonary events according to their weekly home-monitoring measurements. A total of 155 recipients (82 females and 73 males) contributed 1944 weekly records for the training (420), testing (786), and prospective evaluation (738) data sets. Weekly records contained daily values of forced expiratory volume at 1 second and respiratory symptoms, which were the inputs for the triage rules. Results Sensitivity and specificity were greater than 90% for the prospective evaluation comparing the computer decision support system with the manual nurse review of the same home-monitoring reports. Conclusions Algorithm performance in identifying lung recipients who should be placed on a "watch" list for the potential to develop acute bronchopulmonary events is comparable to the standard human clinical review of the same weekly home-monitoring data.

Home monitoring for lung transplant candidates.

Home monitoring by lung transplant recipients has been effective for early detection of clinical problems. This study used an electronic diary for home monitoring by lung transplant candidates to improve communication between candidates and the transplant team. Candidates were randomized into control (52 subjects following standard telephone reporting procedures) and intervention (67 subjects using an electronic diary to record and transmit a range of health-related measures) groups. Outcome measures were monitoring adherence and level of communication (for monitor acceptability and utilization), hospital length of stay after transplantation and survival at 4 months (for clinical effectiveness). Subjects used the diary without difficulty and with good adherence. Subjects and coordinator contacts were similar between groups; intervention group subjects were positive regarding contact based on diary use. There were no significant differences in clinical outcomes between groups. Changing diary questions might improve the effectiveness of electronic monitoring for lung transplant candidates.

Complementary and alternative therapies: what is their place in the management of chronic pain?

Nurses have used complementary therapies for many years to relieve anxiety, promote comfort, and reduce or alleviate pain. The therapies described in this article are examples of the many therapies available for nurses to consider when planning care for patients with chronic pain. The increasing body of scientific knowledge is providing more guidance about the efficacy of specific therapies. As with all interventions, ongoing evaluation about the effectiveness of a therapy for each patient is an important component of quality nursing care. Complementary therapies provide an avenue for nurses to be autonomous in furthering the relief of chronic pain, as many of these therapies fall within the domain of nursing. Incorporating selected therapies into the plan of care provides multiple opportunities for nurses to demonstrate caring, a premier characteristic of nursing. A number of the complementary therapies, such as journaling, hand massage, and imagery, can be taught to patients and their families, thus promoting self-care. Anecdotal evidence and findings from numerous smaller studies provide some support for the use of many complementary therapies to manage chronic pain or their use as adjuncts in the treatment regimen. Still, the nurse must weigh the risks and benefits before suggesting a therapy to a patient. Evaluating the effectiveness of the complementary therapy to promote comfort in patients with chronic pain is essential. Obtaining this information is not only critical to the care of a particular patient, but these data will assist nurses in learning more about specific therapies. Most importantly, nurses need to pursue research to further the scientific basis for many of the complementary therapies.

Cultural related complementary therapies: their use in critical care units.

Complementary therapies are becoming widely used in health care in the United States. Most nurses, as are many Americans, are familiar with complementary therapies such as imagery, aromatherapy, massage, and healing touch. Many nurses, however, are not familiar with complementary therapies that are widely used in other countries and cultures. This article delineates reasons necessitating nurses to increase their knowledge about other health systems, provides examples of therapies used in selected cultures, and describes ways in which critical care nurses can incorporate these into the plan of care for patients in critical care units.

Defining characteristics of expertise in Japanese clinical nursing using the Delphi technique.

A four-round Delphi technique was conducted on 127 experienced Japanese nurses to develop a consensus of opinion on the defining characteristics underlying expertise, and the prime requirements for the development of expertise in clinical nursing. Sixteen statements identified as the prime defining characteristics underlying expertise indicated that experienced Japanese nurses' picture of expertise is general, comprehensive and focused on task expertise. Four prime requirements for the development of expertise identified indicated that neither experience nor accumulation of theoretical knowledge alone is sufficient to develop expertise; but that motivation and attitude do play an essential role in the development of expertise.

Translation and equivalence: the Profile of Mood States Short Form in English and Chinese.

As international research collaborations increase, health care professionals are becoming more aware of the advantages of using common measures to compare outcomes of assessments across cultures. Measuring mood states across diverse cultures is important for understanding the universal aspects of mood and measuring outcomes of nursing interventions. The purpose of this article is to describe the process used to translate the Profile of Mood States Short Form from English to Chinese and to assess the equivalence of this instrument in the two languages. The translated Chinese version of the instrument was found to be as reliable as the original English version and is appropriate for use with Chinese elders who speak either Mandarin or Taiwanese.

Health locus of control and adherence with home spirometry use in lung transplant recipients.

Home monitoring is an effective tool that can be used to promote the health of lung transplant recipients, but only if the recipients transmit data to the healthcare team. This study examines the relationship of the Multidimensional Health Locus of Control scale to adherence with home spirometry use. Form C of this scale was mailed to 139 eligible lung and heart-lung transplant recipients. Eighty-three respondents returned the questionnaire. The respondents were on average 4 years older and had greater adherence than nonrespondents. Men tended to score higher than women on all the subscales. These scales were not related to type of transplant or underlying disease. Adherence was also unrelated to the Multidimensional Health Locus of Control scale, with little difference in adherence across persons with various levels of the health locus of control subscales.

Healing the heart: integrating complementary therapies and healing practices into the care of cardiovascular patients.

Complementary therapies and healing practices have been found to reduce stress, anxiety, and lifestyle patterns known to contribute to cardiovascular disease. Promising therapies include imagery and hypnosis, meditation, yoga, tai chi, prayer, music, exercise, diet, and use of dietary supplements. Many of these complementary approaches to healing have been within the domain of nursing for centuries and can readily be integrated into the care of patients with cardiovascular disease. While individual complimentary modalities hold considerable merit, it is critical that the philosophy underlying these therapies--caring, holism, and harmony--also be understood and honored.
