Genetic parameters for meat and fat quality and carcass composition traits in Iberian pigs

Carcass composition and quality traits were measured in heavy Iberian pigs after extensive handling. The weights of trimmed hams, forelegs and loins were recorded on 2170-2553 pigs, intramuscular fat content in M. longissimus (IMF) on 1489 and percentages of palmitic, stearic, oleic and linoleic acids in the subcutaneous fat on 1495 pigs, slaughtered at about 160 kg live weight. For carcass traits the heritability estimates ranged from 0.28 to 0.41. Heritability estimate for IMF was 0.25 and estimates of heritability for the measured fatty acids ranged from 0.29 to 0.41. The estimated genetic correlations (rg) suggest antagonism between IMF and weights of hams (rg=-0.30) and loins (rg=-0.33) and an unfavourable positive association of premium cuts with linoleic acid content (rg: 0.31-0.57). The incorporation of meat and fat quality traits to the selection aims of the breeding scheme for Iberian pigs seems advisable.

Pain Measurement in Older Adults With Head and Neck Cancer and Communication Impairments

The ability to communicate the presence of pain by means of verbal and nonverbal communication is crucial to facilitate the assessment of pain. Patients with communication impairment (CI) are limited in their ability to verbally report their pain and, consequently, mechanisms to elicit information about the pain experience must incorporate simple and valid methods to accomplish this goal. Pain measurement and the impact of the pain experience in older adults with CI are areas that have been studied on a limited basis in nursing. This study compared the effectiveness of 3 pain assessment tools in measuring pain intensity in the older adults with head and neck cancer and with CI. Multivariate repeated-measures analysis of variance revealed that there were no significant differences in the mean pain intensity scores when subjects used the Numeric Rating Scale, the Faces Pain Scale, and the Visual Analogue Scale at 3 different time intervals. The highest correlation coefficients between pain measurement tools were identified during the third time when the pain measurement tools were used to rate pain intensity. Subjects identified the Numeric Rating Scale as the preferred method to rate pain intensity. Canonical correlation analysis demonstrated that among the demographic variables evaluated in the study, education explained the largest variance in composite of the pain measurement scales.

The impact of music interventions on anxiety for adult cancer patients: a meta-analysis and systematic review.

Introduction. Listening to music can positively benefit neurophysiological and emotional responses as well as promote relaxation, which may be especially beneficial for cancer patients undergoing painful and anxiety inducing treatments. The purpose of the present study was to conduct an evidenced-based systematic review and meta-analysis of randomized controlled trials of music interventions to reduce anxiety for adult cancer patients undergoing medical treatment. Methods. A systematic literature search was conducted and data were abstracted from all eligible studies. Studies were included if they tested a music therapy randomized controlled trial in adult cancer patients (in active treatment), assessed anxiety postintervention using a validated measure, were published in English (or were translatable), and accessible in full text. Studies were qualitatively reviewed by the first author and 2 raters independently assessed each study using the PEDro scale. Standardized mean differences between experimental and control groups were calculated for studies meeting a specified methodological rigor score with accessible means and standard deviations postintervention. Heterogeneity and publication bias were explored. Results. Thirteen randomized controlled trials were included with 4 eligible for meta-analysis. Studies varied in intervention methodology and utilization of anxiety measures. Almost all studies reported either a significant difference in anxiety between groups postintervention or a significant decrease in anxiety over time in the music intervention group. Meta-analytic results of 4 studies (4/13) demonstrated that differences in anxiety between experimental and control groups were not significant in the main analysis or subgroup analysis. Studies demonstrated heterogeneity in anxiety results. Publication bias was not evident. Conclusion. The meta-analytic results failed to demonstrate a positive effect on anxiety among adult cancer patients in treatment but may in part be attributed to the small sample size. These findings are in contrast to a prior meta-analysis that analyzed all studies regardless of methodological rigor. More research is needed to ascertain the most optimal intervention methodology and which cancer populations or treatment modalities are appropriate for such an intervention.

Prevalence of Sudden Speechlessness in Critical Care Units

Sudden speechlessness (SS) is commonly experienced by patients admitted to critical care units. Although literature findings document challenges associated with periods of SS, the prevalence is unknown. The purpose of this study is to determine the prevalence and characteristics of adult SS patients in four critical care units at a university-affiliated tertiary care hospital. Data are collected on 9 randomly selected days over a 4-month period. The daily prevalence of SS ranges from 16% to 24% in each unit. Characteristic data collected includes patient age, gender, medical diagnosis related to SS episode, type of speechlessness, days since SS began, and communication strategies in use. Respiratory intubation related to various clinical diagnoses is the main cause for SS. Use of multiple specific strategies to convey needs during SS periods are identified. Follow-up studies to further define the prevalence of SS in settings beyond the critical care environment are recommended.

Development of a communication intervention to assist hospitalized suddenly speechless patients

Healthcare staff face significant challenges while caring for hospitalized patients experiencing sudden inability to verbalize their needs (sudden speechlessness). Familiar methods of communication such as non-verbal strategies are limited and often fail to assist suddenly speechless patients (SS) communicate their needs. Consequently, strategies tailored to the needs of hospitalized speechless patients are necessary, and must consider factors intrinsic to the patients and the complexities of the acute care environment. The feasibility and usability of a multi-functional prototype communication system (speech-generating device) tailored to the needs of hospitalized SS patients was evaluated in this pilot study. Adult SS patients admitted to the intensive care setting (n=11) demonstrated independent use of a multi-functional communication system that integrated messages and strategies tailored to the needs of the hospitalized SS patient. Participants reported high satisfaction levels and considered the use of the technology of high importance during an SS event. Additional research should focus on evaluating the impact of technology specific communication interventions on enhancing the communication process between SS patients and healthcare staff.

Nurses’ Experiences of Communicating With Hospitalized, Suddenly Speechless Patients

We used a qualitative focus group design to explore the experiences and challenges of nurses who work with hospitalized patients experiencing the sudden inability to verbalize their needs, also known as sudden speechlessness. In response to open-ended questions in facilitated focus groups, 18 nurses discussed issues around the care and communication needs of suddenly speechless (SS) patients. Nurses identified multiple, commonly occurring communication challenges when caring for SS patients. They believed these challenges led to poorer recognition of patient needs, with the potential for compromised patient care. Nurses described how the lack of reliable strategies to facilitate communication sometimes resulted in negative patient outcomes, including unmet psychosocial needs and the potential that informed consent and educational issues were being inadequately addressed for the SS patients. Even experienced nurses indicated ongoing problems in communicating with SS patients, despite using a multitude of strategies, leaving many to deal with issues of frustration and role conflict.

Feasibility of the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program for symptom improvement among breast cancer survivors

The purpose of this pilot study was to test the feasibility of delivering the mobile mindfulness‐based stress reduction for breast cancer (mMBSR(BC)) program using an iPad and to evaluate its impact on symptom improvement.
