After the treatment, complete remission from lymphadenopathy was achieved, whereas the gastric lesion accumulated more radiotracers compared with baseline levels. Despite our incorrect initial assumption of B-cell transformation, molecular imaging was able to profile the characteristics of these 2 diseases.

68Ga-pentixafor PET/CT was reported to have a high sensitivity in detecting tumor involvement of Waldenström macroglobulinemia/lymphoplasmacytic lymphoma (WM/LPL) in our previous study. We aimed to further investigate its value in response assessment in WM/LPL.

Fifteen patients with WM/LPL were recruited in a prospective cohort study and underwent both 68Ga-pentixafor and 18F-FDG PET/CT at baseline and posttreatment. PET/CT-based responses were analyzed with visual assessments and compared with clinical response.

At baseline, all of the 15 patients had a positive 68Ga-pentixafor PET/CT scan, whereas 18F-FDG PET/CT was positive in 11/15 patients. After chemotherapy, the overall response rate was 86.7% (13/15), and 68Ga-pentixafor PET/CT showed different degree of tumor response from baseline in these patients. In the 2 patients with progressive disease, 68Ga-pentixafor PET/CT detected new lesions or remarkable increase of 68Ga-pentixafor uptake in tumor involvements. However, 18F-FDG PET/CT failed to detect the improvement of disease in 6/13 patients and missed disease progression in 1 of the 2 patients.

68Ga-pentixafor PET/CT outperformed 18F-FDG PET/CT in response assessment of WM/LPL.

Guidelines are essential to support appropriate medical management. The objective of our paper is to highlight the need for such recommendations, to reinforce strategies in place and to promote the creation of multidisciplinary networks to provide the most appropriate care to patients and to improve it.

Gynecological rare cancers are not that rare since they represent around 50% of all gynecological cancers. Surgery remains the cornerstone of management for all subtypes. Apart from malignant ovarian germ-cell tumors for which conventional chemotherapy was proven to be efficient, response to standard systemic treatment for other gynecological cancers are disappointing. selleck Better understanding of these pathologies is needed and requires more adapted management.

Rare cancers are substantially heterogeneous but raise the need of integrating new cases in dedicated networks to enhance and homogenize medical practices. Centralized diagnosis, improved medical practice based on regularly updated international guidelines, and inclusion in innovative clinical trials linked to preclinical studies are essential to contribute to the promotion of improvement in patient care.

Uterine sarcomas are rare and are often challenging to differentiate on imaging from benign mimics, such as leiomyoma. As functional MRI techniques have improved and new adjuncts, such as machine learning and texture analysis, are now being investigated, it is helpful to be aware of the current literature on imaging features that may sometimes allow for preoperative distinction.

MRI, with both conventional and functional imaging, is the modality of choice for evaluating uterine mesenchymal tumors, especially in differentiating uterine leiomyosarcoma from leiomyoma through validated diagnostic algorithms. MRI is sometimes helpful in differentiating high-grade stromal sarcoma from low-grade stromal sarcoma or differentiating endometrial stromal sarcoma from endometrial carcinoma. However, imaging remains nonspecific for evaluating rarer neoplasms, such as uterine tumor resembling ovarian sex cord tumor or perivascular epithelioid cell tumor, primarily because of the small number and power of relevant studies.

Through advances in MRI techniques and novel investigational imaging adjuncts, such as machine learning and texture analysis, imaging differentiation of malignant from benign uterine mesenchymal tumors has improved and could help reduce morbidity relating to misdiagnosis or diagnostic delays.

Gestational trophoblastic disease (GTD) is a group of heterogeneous disorders characterized by abnormal proliferation of trophoblastic tissue. GTD is a rare disease that is curable in the vast majority of patients when managed appropriately. The aim of the review is to discuss the important steps necessary to establish a center of excellence for GTD.

Care of patients with a rare disease is complicated by lack of strong evidence, scattering of patients across the country and limited expertise of medical professionals. The establishment of a center of excellence requires awareness of its benefit, funding, a solid business case and most of all dedicated clinicians. A multidisciplinary team and formulation of national guidelines are important steps before clinical pathways can be developed and treatment can be evaluated for improvement of care and research purposes. International embedding can facilitate the process and lead to the development of a (inter) national acknowledged sustainable center of excellence.

Centers of excellence could optimize the care of patients with GTD and promote research.

This study evaluated the effects of a novel nutrition and movement science after-school program integrating laboratory experiences for minority children. Laboratory experiences demonstrated how the body moves, functions, and performs in response to exercise and healthy nutrition.

A total of 76 children from 4 after-school programs that were primarily Latino and black were randomly assigned to either an experimental translational health in nutrition and kinesiology (THINK; n = 46) or standard curriculum that served as the control group (CON; n = 30). An analysis of covariance controlling for baseline values was used to compare differences between THINK and CON after the 4-month intervention.

Following the program, THINK participants evidenced lower triceps and subscapular skinfold thickness (P < .01 and <.05, respectively). THINK students showed greater improvements in aerobic fitness, grip strength, and agility than CON (P < .01, <.01, and <.05, respectively). Participants in THINK also demonstrated higher scores on their nutrition habits/behaviors questionnaire (P < .01), nutrition science (P < .05), and exercise fitness tests (P < .001) than CON.

An innovative curriculum featuring nutrition and kinesiology education interfaced with hands-on laboratory experiences and physical activities can improve physical outcomes and health-related behaviors in after-school programs serving minority children.

Using self-determination theory as a framework, the aim of this study was 2-fold (1) identify different profiles of motivational strategies used by exercise professionals and (2) examine associations of these motivational profiles with work-related variables measures, perceived job pressures, need satisfaction/frustration, and perceived exercisers' motivation.

Participants were 366 exercise professionals (193 males; experience = 7.7 [5.8]y) currently working in health and fitness settings.

Latent profile analysis identified a 3-profile model (1) most need-supportive and least controlling (NS+; n = 225), (2) less need-supportive and slightly controlling (NS-; n = 42), and (3) most controlling and slightly need-supportive (mixed; n = 99). Professionals working less than 20hours per week, more experienced, and female were more likely to integrate NS+, which was also associated with higher levels of work-related need satisfaction and clients' perceived self-determination, and lower levels of job pressures and need-frustration. Conversely, NS- displayed the most maladaptive pattern of associations.

The present findings highlight the importance of analyzing the correlates of different professional profiles, namely to help health and fitness organizations to provide high-quality motivational practices within an appropriate environment both for professionals and clients.

Little is known whether physical activity (PA)-promoting environments are equally accessible to children with divergent socioeconomic status (SES) in low-/middle-income countries. The authors, therefore, examined whether South African children from poorer versus wealthier families living in marginalized communities differed in moderate to vigorous PA and cardiorespiratory fitness. We also tested associations between family car ownership and PA/cardiorespiratory fitness.

Parents/guardians of 908 children (49% girls, mean age = 8.3 [1.4] y) completed a survey on household SES. PA was assessed via 7-day accelerometry, parental and child self-reports, and cardiorespiratory fitness with the 20-m shuttle run test.

Based on accelerometry, most children met current moderate to vigorous PA recommendations (≥60min/d). About 73% of the children did not engage in structured physical education lessons. Whereas children of the lowest SES quintile accumulated higher levels of device-based moderate to vigorous PA, peers from the highest SES quintile engaged in more sedentary behaviors, but self-reported higher engagement in sports, dance, and moving games after school. Families' car ownership was associated with higher parent/self-reported leisure-time PA.

A deeper understanding is needed about why wealthier children are more sedentary, but simultaneously engage in more leisure-time PA. The fact that access to structural physical education is denied to most children is critical and needs to be addressed.

However, the study of CD1c-restricted T cells is hampered by the presence of an abundantly expressed, non-T cell receptor (TCR) ligand for CD1c on blood cells, confounding analysis of TCR-mediated CD1c tetramer staining. Here, we identified the CD36 family (CD36, SR-B1, and LIMP-2) as ligands for CD1c, CD1b, and CD1d proteins and showed that CD36 is the receptor responsible for non-TCR-mediated CD1c tetramer staining of blood cells. Moreover, CD36 blockade clarified tetramer-based identification of CD1c-restricted T cells and improved identification of CD1b- and CD1d-restricted T cells. We used this technique to characterize CD1c-restricted T cells ex vivo and showed diverse phenotypic features, TCR repertoire, and antigen-specific subsets. Accordingly, this work will enable further studies into the biology of CD1 and human CD1-restricted T cells.
