Portion control tableware differentially impacts eating behaviour in women with and without overweight.

Portion control tableware has been described as a potentially effective approach for weight management, however the mechanisms by which these tools work remain unknown. We explored the processes by which a portion control (calibrated) plate with visual stimuli for starch, protein and vegetable amounts modulates food intake, satiety and meal eating behaviour. Sixty-five women (34 with overweight/obesity) participated in a counterbalanced cross-over trial in the laboratory, where they self-served and ate a hot meal including rice, meatballs and vegetables, once with a calibrated plate and once with a conventional (control) plate. A sub-sample of 31 women provided blood samples to measure the cephalic phase response to the meal. Effects of plate type were tested through linear mixed-effect models. Meal portion sizes (mean ± SD) were smaller for the calibrated compared with the control plate (served: 296 ± 69 vs 317 ± 78 g; consumed: 287 ± 71 vs 309 ± 79 g respectively), especially consumed rice (69 ± 24 vs 88 ± 30 g) (p < 0.05 for all comparisons). The calibrated plate significantly reduced bite size (3.4 ± 1.0 vs 3.7 ± 1.0 g; p < 0.01) in all women and eating rate (32.9 ± 9.5 vs 33.7 ± 9.2 g/min; p < 0.05), in lean women. Despite this, some women compensated for the reduced intake over the 8 h following the meal. Pancreatic polypeptide and ghrelin levels increased post-prandially with the calibrated plate but changes were not robust. Plate type had no influence on insulin, glucose levels, or memory for portion size. Meal size was reduced by a portion control plate with visual stimuli for appropriate amounts of starch, protein and vegetables, potentially because of the reduced self-served portion size and the resulting reduced bite size. Sustained effects may require the continued use of the plate for long-term impact.

Stem Cell Transplant Experiences Among Hispanic/Latinx Patients: A Qualitative Analysis.

BACKGROUND: Hispanic/Latinx (H/L) patients with cancer treated with stem cell transplant are vulnerable to adverse outcomes, including higher mortality. This study explored their unmet transplant needs, barriers, and facilitators. METHODS: Eighteen English- or Spanish-speaking H/L patients (M age = 59.2) who had a transplant in the past year were interviewed about their transplant experience and rated their interest in receiving information about transplant topics (0 = not at all to 10 = extremely). RESULTS: Content analysis revealed five main themes: (1) pre-transplant barriers and concerns; (2) complex relationships with medical teams; (3) informational mismatch; (4) impacts on daily life after transplant; and (5) methods of coping. Participants were most interested in information about ways of coping with transplant (M = 9.11, SD = 1.45) and words of hope and encouragement (M = 9.05, SD = 1.80). At just above the scale's midpoint, they were least interested in information about side effects and unintended consequences of transplant (M = 5.61, SD = 3.85). CONCLUSIONS: Cultural factors, social determinants, and structural inequalities give rise to unique needs in this growing patient population. Healthcare team members and researchers can better meet the needs of H/L transplant recipients through attention to described considerations, such as financial barriers, communication difficulties, family dynamics, and coping styles.

Ten Approaches That Improve Immunostaining: A Review of the Latest Advances for the Optimization of Immunofluorescence.

Immunostaining has emerged as one of the most common and valuable techniques that allow the localization of proteins at a quantitative level within cells and tissues using antibodies coupled to enzymes, fluorochromes, or colloidal nanogold particles. The application of fluorochromes during immunolabeling is referred to as immunofluorescence, a method coupled to widefield or confocal microscopy and extensively applied in basic research and clinical diagnosis. Notwithstanding, there are still disadvantages associated with the application of this technique due to technical challenges in the process, such as sample fixation, permeabilization, antibody incubation times, and fluid exchange, etc. These disadvantages call for continuous updates and improvements to the protocols extensively described in the literature. This review contributes to protocol optimization, outlining 10 current methods for improving sample processing in different stages of immunofluorescence, including a section with further recommendations. Additionally, we have extended our own antibody signal enhancer method, which was reported to significantly increase antibody signals and is useful for cervical cancer detection, to improve the signals of fluorochrome-conjugated staining reagents in fibrous tissues. In summary, this review is a valuable tool for experienced researchers and beginners when planning or troubleshooting the immunofluorescence assay.

Sistemas de significados en torno a la experiencia erótica y los abusos sexuales en la infancia / Systems of Meanings concerning the Erotic Experience and Child Sexual Abuse

Resumen El abuso sexual infantil puede dejar efectos en la experiencia erótica de las personas. Sin embargo, cuando dicha vivencia es narrada por los participantes ellos podrían significar de diversas maneras sus posibles consecuencias. Por lo tanto, llevamos a cabo una investigación cualitativa, bajo el marco teórico del construccionismo social, en la que participaron cuatro mujeres y dos hombres, quienes experimentaron abusos sexuales en la infancia. Realizamos entrevistas semi-estructuradas y temáticas. En el análisis de las narrativas, observamos la importancia de los constructos de género tradicionales en las primeras experiencias eróticas. Adicionalmente, las vivencias de abusos sexuales permitieron dar sentido a las dificultades observadas en la edad adulta. Finalmente, destacamos que el valor otorgado al amor fue un elemento que permitió la resignificación positiva de la experiencia.

Abstract Child sexual abuse may have effects on the erotic experience of people. However, when such an episode is narrated by the participants, they might give meaning to its possible consequences in different ways. Therefore, we carried out a qualitative research within the theoretical framework of social constructionism involving four women and two men who experienced sexual abuse in childhood. We conducted semi-structured and thematic interviews. In the analysis of the narratives, we noted the importance of the traditional gender constructs in the first erotic experience. Additionally, the experiences of sexual abuse helped to make sense of the difficulties observed in adulthood. Finally, we highlight that the value attributed to love was an element that allowed the positive re-signification of the experience.

Cancer-Relevant Self-Efficacy Is Related to Better Health-Related Quality of Life and Lower Cancer-Specific Distress and Symptom Burden Among Latina Breast Cancer Survivors.

BACKGROUND: Latina breast cancer survivors (BCS) often report poorer health-related quality of life (HRQOL), higher symptom burden, and greater psychosocial needs compared to non-Latina BCS. However, Latinas are underrepresented in cancer survivorship research and more work is needed to examine the factors contributing to these psychosocial disparities. This study aimed to evaluate potentially modifiable patient characteristics associated with HRQOL, breast cancer concerns, and cancer-specific distress among Latina BCS. METHODS: Baseline data was evaluated in 95 Latina BCS who participated in a smartphone-based psychosocial intervention designed to improve HRQOL. Hierarchical linear regression analyses were conducted to evaluate the associations between modifiable factors that have been shown to favorably impact outcomes in cancer populations (i.e., cancer-relevant self-efficacy, breast cancer knowledge) with overall and domain-specific HRQOL, breast cancer symptom burden, and cancer-specific distress, after controlling for sociodemographic and cancer-related characteristics. RESULTS: Greater cancer-relevant self-efficacy was related to better overall HRQOL as well as better social, emotional, and functional well-being domains. Greater cancer-relevant self-efficacy was also related to less breast cancer symptom burden and less cancer-specific distress. Breast cancer knowledge was not associated with any of the study outcomes. CONCLUSIONS: Results demonstrate that cancer-relevant self-efficacy is a significant correlate of general and domain-specific HRQOL, breast cancer symptom burden, and cancer-specific distress among Latina BCS. Future interventions in this population should target cancer-relevant self-efficacy as a possible mechanism to improve HRQOL outcomes and survivorship experiences for Latina BCS.
