AI Article Synopsis
- The study addresses the lack of research on muscle dysmorphia in Brazilian women, a group experiencing high body dissatisfaction and a desire for muscularity.
- The researchers conducted a psychometric evaluation of the Muscle Dysmorphic Disorder Inventory (MDDI) adapted into Brazilian Portuguese with a sample of 515 women.
- Their findings confirmed the original three-factor structure of the MDDI, demonstrating good reliability and validity, which supports its use in understanding muscle dysmorphia in this demographic.
Article Abstract
Despite high levels of body dissatisfaction and an increasing drive for muscularity among Brazilian women, most of the existing literature on muscle dysmorphia focuses on men and has mainly been conducted in Western and English-speaking regions. As a result, one of the most widely used assessment tools for symptoms of the disorder, the Muscle Dysmorphic Disorder Inventory (MDDI), has not yet been evaluated in Brazilian women-an at-risk population. In the present study, we perform a psychometric evaluation of the Brazilian Portuguese translation of the MDDI in a sample of 515 women. We evaluated the factor structure using a two-step, split-sample exploratory and confirmatory factor analytic approach, which supported the original three-factor structure of the measure. Additionally, we found good internal consistency, convergent validity, and test-retest reliability of the measure. Collectively, these results support the use of the measure in Brazilian women and provide a foundation to expand the literature in this population.

Aim: Cemiplimab has demonstrated significantly longer survival than physician's choice of chemotherapy in patients with recurrent cervical cancer after first-line platinum-containing chemotherapy. We report the final survival analysis from the phase III randomized study (EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9).
Methods: Cemiplimab (n = 304) or chemotherapy (n = 304) were administered every 3 weeks.

In this essay, we will present arguments for a negative answer to the debate question: "Is publishing ethnobiology data respectful of Indigenous and Local Knowledge holders' rights?" We recognize that ethnobiological research has advanced in recognizing the rights of Indigenous Peoples and Local Communities (IPLC), but we believe that we still have a long way to go in deconstructing colonialism in ethnobiology. In order to be truly respectful, ethnobiologists need to collaborate with IPLC to achieve an ethical science with equity between knowledge systems, fostering the co-production of knowledge from an intercultural science perspective. This essay was written by a group of Brazilian scientists, both IPLC and non-IPLC, and reflects a perspective of the academic universe seen from the place we are, in this multicultural and imbalanced world.

Colorectal cancer (CRC) is commonly treated with intestinal resections that lead to colostomy, which can influence changes in eating habits. This study aimed to analyze energy and nutrient intake, diet quality, and food consumption based on the processing level in CRC patients after colostomy. A prospective study was carried out at three time points (T0-recent colostomy, T1-3 months after colostomy, and T2-6 months after colostomy).
