Conformational risk factors of brachycephalic obstructive airway syndrome (BOAS) in pugs, French bulldogs, and bulldogs.
Extremely brachycephalic, or short-muzzled, dog breeds such as pugs, French bulldogs, and bulldogs are prone to the conformation-related respiratory disorder-brachycephalic obstructive airway syndrome (BOAS). Affected dogs present with a wide range of clinical signs from snoring and exercise intolerance, to life-threatening events such as syncope. In this study, conformational risk factors for BOAS that could potentially aid in breeding away from BOAS were sought. Six hundred and four pugs, French bulldogs, and bulldogs were included in the study. Soft tape measurements of the head and body were used and the inter-observer reproducibility was evaluated. Breed-specific models were developed to assess the associations between the conformational factors and BOAS status based on functional grading. The models were further validated by means of a BOAS index, which is an objective measurement of respiratory function using whole-body barometric plethysmography. The final models have good predictive power for discriminating BOAS (-) and BOAS (+) phenotypes indicated by the area under the curve values of >80% on the receiver operating curves. When other factors were controlled, stenotic nostrils were associated with BOAS in all three breeds; pugs and bulldogs with higher body condition scores (BCS) had a higher risk of developing BOAS. Among the standardized conformational measurements (i.e. craniofacial ratio (CFR), eye width ratio (EWR), skull index (SI), neck girth ratio (NGR), and neck length ratio (NLR)), for pugs EWR and SI, for French bulldogs NGR and NLR, and for bulldogs SI and NGR showed significant associations with BOAS status. However, the NGR in bulldogs was the only significant predictor that also had satisfactory inter-observer reproducibility. A NGR higher than 0.71 in male bulldogs was predictive of BOAS with approximately 70% sensitivity and specificity. In conclusion, stenotic nostrils, BCS, and NGR were found to be valid, easily applicable predictors for BOAS (+)
Conceptualizing and measuring strategy implementation – a multi-dimensional view
Through quantitative methodological approaches for studying the strategic management and planning process, analysis of data from 208 senior managers involved in strategy processes within ten UK industrial sectors provides evidence on the measurement properties of a multi-dimensional instrument that assesses ten dimensions of strategy implementation. Using exploratory factor analysis, results indicate the sub-constructs (the ten dimensions) are uni-dimensional factors with acceptable reliability and validity; whilst using three additional measures, and correlation and hierarchical regression analysis, the nomological validity for the multi-dimensional strategy implementation construct was established. Relative importance of ten strategy implementation dimensions (activities) for practicing managers is highlighted, with the mutually and combinative effects drawing conclusion that senior management involvement leads the way among the ten key identified activities vital for successful strategy implementation
Disordered eating behavior, body image, and energy status of female student dancers
Background: Modern culture has stereotyped the female body as one that is continually getting thinner.
Internalization of the ‘thin’ ideal is partly attributable to the inner ideal to be successful combined with the
external pressure imposed by media and others. Many individuals attempt to achieve these ideals by behavior
modification that imposes health risks. Purpose: To investigate disordered eating (DE) behavior and energy
status in female student dancers. Methods: Volunteer dancers (n = 26) aged 19.0 (18.0; 21.0) years, matched by
controls (n = 26) aged 20.0 (19.0; 21.0) years were recruited. Eating Disorder Inventory-3 (EDI-3) subscales,
Three-factor Eating Questionnaire (TFEQ) Cognitive Dietary Restraint (CDR) subscale, and EDI-3 Referral
Form behavioral questions assessed DE behavior. Energy status was assessed with a food record and Actiheart
monitor. Results: Dancers achieved significantly higher scores than controls in all questionnaires, namely:
EDI-3 Drive for Thinness [12.0 (3.0; 19.0) vs. 4.5 (2.0; 9.0), p = .023], EDI-3 Body Dissatisfaction [16.0 (10.0;
25.0) vs. 6.5 (3.0; 14.0), p = .004], and TFEQ-CDR [9.0 (2.0; 15.0) vs. 3.0 (3.0; 7.0), p = .032]; dancers used
excessive exercise to lose weight (19.2% vs. 0%, c2 = 5.53, p = .019), and had lower energy availability (24%
vs. 8%, p < .05) than controls. The average energy balance (EB) was negative for both groups [dancers: EB
= -3896 (-5236; -1222) vs. controls: EB = -2639 (-4744; -789) kJ/day]. Conclusion: Female dancers are at
risk for DE behavior and many have suboptimal energy status which may be related to their quest to achieve
a more desirable appearance; education on healthy weight management practices is needed
Factors influencing low sodium intake in people with non‐dialysis dependent chronic kidney disease
To evaluate dietary sodium intake in people with chronic kidney disease (CKD) and identify contributing factors to low sodium intake by applying the Theory of Planned Behaviour (TPB) framework.Non-dialysed people with CKD completed a 24-hour urinary sodium excretion test and Scored Salt Questionnaire (SSQ). A survey including socio-demographic information, Brief Illness Perception Questionnaire, Short Sodium Knowledge Survey and Dietary Sodium Restriction Questionnaire based on TPB measured the factors contributing to dietary adherence.Sixty-three people [age: 71 (IQR: 64-77); 27% female] participated with 80% having high urinary sodium excretion [median: 134 mmol/day (111; 183)] but only 40% reported high sodium intake [SSQ score = 53 (39; 75)]. Overall sodium knowledge was high in 57% of participants although only 33% had seen a dietitian. There was a positive correlation between attitude towards a low-sodium diet and subjective norm (social expectations), r = 0.44, p
Perceived Benefits of a Standardized Patient Simulation in Pre-Placement Dietetic Students
The purpose of this study was to evaluate the effect of a simulation-based learning (SBL) experience on perceived confidence in monitoring and evaluation, as part of the delivery of nutrition care of pre-placement dietetic students, and to describe their perceived value of the learning experience post-placement. A mixed method explanatory sequential study design was used. A confidence appraisal scale was developed and completed by students before (n = 37) and after (n = 33) a low fidelity simulation using a volunteer patient in an acute care setting. Two semi-structured focus group discussions with post-placement students (n = 17) were thematically analysed, grounded in phenomenology. Overall perceived confidence in monitoring and evaluating, as part of nutrition care, improved after the simulation [pre-SBL: 74 (62–83) vs. post-SBL: 89 (81–98.5), p = 0.00]. Two factors emerged to modulate confidence, namely (i) structure and (ii) authentic learning. Structure in turn was modulated by two key factors; safety and process. A low fidelity simulation using a standardised patient can improve students’ perceived confidence in monitoring and evaluation, and a well-structured authentic learning experience was valued and positively perceived by most dietetic students
Dietary Inflammatory Index and Associations with Sarcopenia Symptomology in Community-Dwelling Older Adults
Low-grade systemic inflammation is a key driver of muscle degeneration in older adults, and diets with pro-inflammatory properties may further contribute to loss of muscle mass, strength and function. Therefore, this research aimed to explore the associations between the inflammatory potential of the diet and measures of sarcopenia symptomology in community-dwelling older adults. Upper (handgrip strength, HGS) and lower extremity (sit-to-stand) muscle strength, physical performance (timed-up-and-go, TUG) and appendicular skeletal muscle mass (ASM) was assessed according to the European Working Group on Sarcopenia in Older People version 2 (EWGSOP2) criteria. Multiple 24-hr dietary recalls were used to calculate the Dietary Inflammatory Index (DII), which was then used to group participants into anti- and pro-inflammatory dietary groups. Multiple linear regression investigated associations between DII, muscle strength, physical performance, and muscle quantity adjusted for age, gender, comorbidities, waist circumference and physical activity. Adults 65–85 years (n = 110, 72.1 ± 4.7 years, 76.4% female) were recruited. One participant was identified with sarcopenia, 35.2% were pre-frail, or frail. More participants with a pro-inflammatory DII score had low muscle quantity than those with anti-inflammatory DII (3.4% vs. 6.4%, x2 = 4.537, p = 0.043) and DII was negatively associated with HGS (β = −0.157, p = 0.016) and ASM (β = −0.176, p = 0.002) which remained significant after adjusting for covariates. In this population, DII was associated with less favorable muscle strength, physical performance, and muscle quantity
Dietary strategies for chemotherapy-induced nausea and vomiting: A systematic review
Background & aimsChemotherapy-induced nausea and vomiting (CINV) is one of the most distressing cancer treatment side effects, affecting 20–70% of patients despite routine antiemetic prescription. Although dietary modifications are routinely recommended in clinical practice, there is lack of data synthesis to determine which dietary strategies for managing CINV are supported by quality evidence. This systematic review was conducted to examine the effect of dietary strategies on incidence and severity of CINV in adults compared with no intervention, usual care, or alternative strategies.MethodsFive electronic databases were searched from inception to 15th July 2021 for original research studies of interventional or observational design assessing dietary strategies for CINV. The quality of evidence was appraised, data were synthesized narratively, and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment of the certainty of the evidence was applied.ResultsTwenty-one studies were included, 10 (48%) interventional studies and 11 (52%) observational studies. Most interventional and observational studies had a high or neutral risk of bias (70% and 72%, respectively). Of the interventions studied, strongest evidence with highest certainty was found for the very large positive effect of CINV-specific education and support with a personalized meal plan from a dietician, implemented in person or in writing, for reducing the severity of nausea and overall CINV (effect size: very large; GRADE: high). A statistically significant very large positive effect of ginger tea consumption was also found on overall CINV severity; however, certainty in this effect was very low. Although confidence in the findings from observational studies was very low to low, a statistically significant positive association was also found between a moderate intake of alcohol and incidence of nausea, vomiting, or overall CINV as well as nausea severity; the Mediterranean diet and nausea incidence and severity; and adequate intake of energy, protein, fat, or carbohydrate and nausea or vomiting incidence.ConclusionImproved CINV was associated with CINV-specific nutrition education and support from health professionals. Non-restrictive dietary patterns that include adequate energy and macronutrient intakes, particularly protein, and include ginger, and Mediterranean diet concepts may benefit CINV; however, the confidence in the body of evidence to inform these conclusions is mostly very low to moderate. Future rigorous trials with adequate sample sizes, clearly defined dietary strategies, and valid outcome measures are warranted prior to dietary strategies being routinely prescribed alongside antiemetic regimens
