Effects of starvation on energy density of juvenile chum salmon (Oncorhynchus keta) captured in marine waters of Southeastern Alaska

We conducted laboratory starvation experiments on juvenile chum salmon (Oncorhynchus keta) captured in the neritic marine waters of northern Southeast Alaska in June and July 2003. Temporal changes in fish energy density (whole body energy content [WBEC], cal/g dry weight), percent moisture content, wet weight (g), length (mm), and size-related condition residuals were measured in the laboratory and were then compared to long-term field data. Laboratory water temperatures and salinities averaged 9°C and 32 psu in both months. Trends in response variables were similar for both experimental groups, although sampling intervals were limited in July because fewer fish were available (n= 54) than in June (n=101). Overall, for June (45-d experimental period, 9 intervals), WBEC, wet weight, and condition residuals decreased and percent moisture content increased, whereas fork length did not change. For July (20-d experimental period, 5 intervals), WBEC and condition residuals decreased, percent moisture content and fork length increased, and wet weight did not change. WBEC, percent moisture content, and condition residuals fell outside the norm of longterm data ranges within 10–15 days of starvation, and may be more useful than fork length and wet weight for detecting fish condition responses to suboptimal environments

Clowning as Human Rights Activism in Recent Devised Irish Theatre

This article focuses on clown techniques in devised theatre pieces by Charlie O’Neill and Brian Fleming, claiming those strategies as an emergent category of human rights activism in Irish theatre. Fleming’s Trilogy (2011, 2012, 2014) and O’Neill’s Hurl (2003) and Dodgems (2008a) are influenced by clown as practiced by Barabbas, but they return to a more text-driven, issue-based theatre to advocate for human rights. In close-reading these theatre pieces, I examine the following clown techniques: physical theatre, audience participation, parody and reversals of power, and self-examination. I argue that clowning is a growing undercurrent in Irish theatre, advancing human rights speech that challenges neoliberal and conservative views on immigration, racism, poverty, and homosexual rights

Parental Monitoring and Adolescent Sexual Health Outcomes

Adolescents engage in risky health behaviors more than young children and adults. This risk taking is thought to be a result of biological and environmental factors influencing adolescent behavior. Teenagers' engagement in risky sexual behavior puts them at a higher risk for morbidity and social stress resulting from unintended pregnancy and sexually-transmitted infections. This increased risk of morbidity emphasizes the public health significance of adolescent risk behavior. Parental monitoring has been identified as an important protective factor for adolescents' negative sexual health outcomes. However, the distinction between rule-setting and coercive discipline is critical in understanding the influence that parents have over their adolescent's risk taking behavior. Without recognition of the importance of a supportive and trusting parent/adolescent relationship, parental monitoring studies and interventions will be less effective in bringing about behavior change in adolescents and their parents. Perceptions of parental monitoring can vary greatly between adolescents and parents, and thus there is a need for a scale to measure actual parental knowledge of adolescent risk behavior. It is also important to consider the quality of parent and adolescent relationships when attempting to understand the effects of parental monitoring. As a result, the examination of barriers to parental monitoring and the nature of the parent/adolescent relationship are crucial for making a lasting positive impact on adolescent sexual health outcomes

Effective Occupational Therapy Interventions to Decrease Picky Eating in Children: A Systematic Review

PURPOSE: Picky eating is related to the lack of consumption in food variety by children when shown different foods (Wolstenholme et al., 2020). A 2015 study reported that almost half of children experience a period of picky eating at some point during early childhood, including almost 15% of children for whom picky eating does not resolve by age 6 (Cardona et al., 2015). The purpose of this systematic review is to identify interventions within the scope of occupational therapy that increase food acceptance in children under the age of seven years who demonstrate picky eating characteristics and who have no underlying health conditions. DESIGN: This systematic review included articles relevant to children under the age of 7 with no underlying health conditions, addressed unfamiliar food introductions or picky eating interventions, and assessed food consumption and variety. Level I evidence published in 2012 to 2023 in peer-reviewed journals was included. METHOD: We reviewed the title and abstract of 738 articles from four different literature databases; each title and abstract was reviewed by two researchers to build consensus about which articles would be considered for full-text review. Then we reviewed the full text of 102 articles that appeared to meet or might meet the study’s inclusion criteria, all of which were reviewed by at least two researchers. Twelve articles met the inclusion criteria of this study. We used the U.S. Preventive Services Task Force levels of certainty and grade definition to describe the strength of evidence across these 12 studies. RESULTS: We categorized articles into three different themes: taste exposure, nutrition education, and flavor change. Nine articles provided strong support for occupation-based interventions involving taste exposure for improving food acceptance and variety. These interventions consisted of screen-based modeling, offering unfamiliar food at snack times, making the foods into small pieces to eat, and using rewards or praise. There was moderate evidence supporting nutrition education and flavor change; these interventions included picture books, school based nutritional education, flavor change of vegetables, and changing the form of vegetables, respectively. CONCLUSION: Overall, this systematic review identifies several strategies within the scope of occupational therapy practice that may improve food consumption and variety in picky eaters aged seven and under. Eating is a chief activity of daily living and essential to life, and occupational therapy services can address picky eating by using interventions tailored to the individual. Occupational therapy practitioners can use taste exposure to effectively increase food consumption. Since there is moderate evidence to support interventions involving nutrition education and flavor change, practitioners should consider recommending these interventions on a routine basis. Future research could refine protocols’ intervention activities, frequency, and duration. Cardona Cano, S., Tiemeier, H., Van Hoeken, D., Tharner, A., Jaddoe, V. W., Hofman, A., Verhulst, F.

Distinguishing Increased Adiposity and/or Aerobic Deconditioning as Moderators of Low VO2peak in Obese Men

Peak oxygen uptake (V̇O2peak) in a cardiopulmonary exercise test (CPET) is a strong predictor of morbidity, mortality, and quality of life. V̇O2peak in obese individuals is typically below the lower limit of normal (2 transport and utilization, i.e. aerobic deconditioning; or both. We hypothesized a modified CPET, to measure the fraction of maximum isokinetic power that can be supported by aerobic metabolism, will distinguish between adiposity and deconditioning effects on V̇O2peak. PURPOSE: To compare V̇O2peak and isokinetic neuromuscular performance in obese vs non-obese men. METHODS: A modified CPET with maximal (3 s) isokinetic cycling power at baseline and the limit of ramp-incremental (RI) exercise was used to calculate: A) baseline maximum isokinetic power (Piso); B) tolerance index (TI), % of Piso at V̇O2peak; C) fatigue index (FI), % reduction in Piso per RI-watt at V̇O2peak; D) power reserve (PR), isokinetic power available at V̇O2peak expressed as % RI-wattpeak. The FRIEND nomogram was used to predict V̇O2peak. Data are mean(SD) and were assessed by t-test. RESULTS: Compared to controls (n=24), obese men (n=20) were older (32(5) vs 26(7) yr), had greater BMI (38(6) vs 23(2) kg/m2), but were not different in stature (177(5) vs 180(7) cm) or predicted V̇O2peak (3.49(0.49) vs 3.58(0.36) L/min). Obese men had lower V̇O2peak (2.84(0.42) vs 3.71(0.45) L/min, p2peak (82(15) vs 104(12) %, pIndependent of body mass, obese men had preserved leg strength (normal Piso), but the fraction of maximum isokinetic power supported by aerobic metabolism at RI intolerance was reduced (low TI) with greater fatigability (high FI); each consistent with aerobic deconditioning. A modified CPET with maximal isokinetic power measurements can distinguish the effects of increased adiposity from aerobic deconditioning on V̇O2peak in obese men
