Article Synopsis
  • Malnutrition in early childhood can lead to long-term health issues, including obesity, with this study focusing on how maternal perceptions and feeding practices influence infant nutrition in northeastern Mexico.
  • The research assessed 192 mother-infant pairs, revealing that 38% of infants were overweight/obese while 7% were underweight, and identified key maternal factors like low self-efficacy and inaccurate weight perceptions affecting infant nutritional status.
  • Findings suggest that many mothers lack knowledge about proper feeding practices, with longer sleep duration linked to underweight infants and critical inaccuracies in maternal perceptions of their child’s weight for both underweight and overweight/obese infants.

Radiation therapy, one of the most effective therapies to treat cancer, is highly toxic to healthy tissue. The delivery of radiation at ultra-high dose rates, FLASH radiation therapy (FLASH), has been shown to maintain therapeutic anti-tumor efficacy while sparing normal tissues compared to conventional dose rate irradiation (CONV). Though promising, these studies have been limited mainly to murine models.

Techniques such as ureteral access sheath placement and balloon dilation are utilized to facilitate ureteroscopy. A retrospective review was performed to evaluate the efficacy and complications from ureteral access sheath (UAS) placement with or without sequential ureteral balloon dilation (SBD) in non-prestented patients who underwent ureteroscopy with UAS with or without SBD for renal or proximal ureteral stones from February 2014 to April 2017. This was a two-surgeon series of 124 patients divided into groups of SBD + UAS or direct UAS placement.

Freshwater organisms are often sensitive to pesticides, but their sensitivity varies across different taxa and with pesticide type and action mode, as shown by multiple acute toxicity tests. Such variability hampers predictions about how freshwater ecosystems may be altered by pesticide toxicity, which is especially critical for understudied areas of the world such as the tropics. Furthermore, there is little information about the sensitivity of some organisms that are key components of stream food webs; this is the case of litter-feeding detritivorous invertebrates, which contribute to the fundamental process of litter decomposition.

The expansion of agriculture is particularly worrying in tropical regions of the world, where native forests are being replaced by crops at alarming rates, with severe consequences for biodiversity and ecosystems. However, there is little information about the potential effects of agriculture on the functioning of tropical streams, which is essential if we are to assess the condition and ecological integrity of these ecosystems. We conducted a litter decomposition experiment in streams within a tropical catchment, which were subjected to different degrees of agricultural influence: low (protected area, PA), medium (buffer area, BA) and high (agricultural area, AA).

Background: The inadequate storage of biopharmaceuticals may result in an ineffective therapeutic response since poor conservation can lead to the emergence of protein aggregates and cause immunogenicity in patients, which can increase the risk of adverse events by inducing the production of anti-drug antibodies. This can also lead to significant economic losses for public health, given the high cost of these medicines. The aim of this study was to verify whether the home storage of biopharmaceuticals dispensed by the Unified Public System was in accordance with the manufacturers' specified standards and whether external variables interfered with the correct home storage.

Behavior analysts are increasingly called to serve culturally and linguistically diverse populations. The culture of a population can provide context in which to identify behaviors likely to be reinforced by the client's social environment, stimuli established as reinforcers for client behavior, and behavioral repertoires shaped by the client's social environment. One of the largest and fastest growing minority groups in the United States is the Latinx population.

Reading depends on the integration of both cognitive and motivational factors, yet reading motivation has received little attention in the research literature. The purpose of the present study was to evaluate the psychometric properties of the Baylor Revision of the Motivation to Read Survey (B-MRS; Watkins & Browning, 2015) with a sample of 731 students in Grades 6-8. The results of exploratory and confirmatory factor analyses supported the oblique two-factor structure of the B-MRS, which was invariant across gender, and regression analyses indicated that gender and grade were not significant predictors of reading motivation.
