Background: Celiac plexus block has been commonly utilized for the treatment of chronic pancreatitis-associated abdominal pain. Prospective studies suggest efficacy in 30 to 50% of patients, although no randomized sham-controlled trials have been performed. The objective of this study is to assess the effect of endoscopic ultrasound (EUS)-guided celiac plexus block on abdominal pain in patients with documented chronic pancreatitis. Methods: This is a two-arm randomized sham-controlled trial with blinded evaluators. The study will be conducted at multiple academic sites in the United States who are members of the United States Pancreatic Disease Study Group (USPG). Patients referred for EUS to exclude chronic pancreatitis as a cause of abdominal pain as well as those with established painful chronic pancreatitis undergoing EUS for another indication will be eligible. At the time of EUS with confirmation of chronic pancreatitis by standard EUS diagnostic criteria, patients will be randomized to either celiac plexus block or sham whereby an anesthetic and steroid combination will be injected into the celiac plexus or saline will be injected into the gastric lumen with the same type of needle as used for celiac plexus block, respectively. The main outcome measure will be a 50% reduction in abdominal pain using the Brief Pain Inventory Short Form (BPI-SF) at 1 month post-intervention. A number of secondary outcomes will be measured including visual analog scale (VAS), Comprehensive Pain Assessment Tool Short Form (COMPAT-SF) pain scores, and quality of life using a pancreas-specific validated measure (PANQOLI). Discussion: In this study, the effect of celiac plexus block on abdominal pain in patients with chronic pancreatitis will be compared to a sham intervention. This randomized trial will offer a definitive assessment of the role of celiac plexus block for the treatment of abdominal pain in this setting.

The COVID-19 pandemic drastically affected higher education and higher education students around the world, but few studies of college students' experiences during the COVID-19 pandemic have been conducted in Latin America. This study describes the COVID-19-related experiences and perspectives of Peruvian college students. We surveyed 3,427 full-time college students (average age: 23 years) attending a multi-campus Peruvian university in fall 2020. Participants were recruited through the digital platform of the learning management system at their university, email, and social media. We asked participants how they were managing risks related to COVID-19; the continuity of social, educational, and work activities; and the psychological and economic impacts of the pandemic on their lives. Since March 2020, 73.0% of participants reported COVID-19-related symptoms, but only 33.9% were tested for COVID-19. During the national quarantine imposed by the Peruvian government (March 15–June 30, 2020), 64.3% of participants remained in their house. Furthermore, while 44.0% of participants were working in February 2020 (95% CI: [41.7%, 46.4%]), only 23.6% (95% CI: [21.7%, 25.7%]) were working immediately after the pandemic began (i.e., at the end of April 2020). Participants were more stressed about the health and educational implications of COVID-19 for Peruvian society and their families than about themselves. The public health, economic, and educational implications of COVID-19 on college students are continuing to unfold. This study informed Peruvian higher education institutions' continued response to the COVID-19 pandemic, the progressive return to postpandemic activities, as well as other future pandemics and other crises.

Care homes enable people with advanced physical and cognitive impairment to live well with 24-h support from staff. They are a feature of care systems in most countries. They have proved pivotal to the coronavirus disease 2019 (COVID-19) response. We searched Age and Ageing for care-home articles published since 2015. From these we collated 42 into the Age and Ageing care-home collection. This collection draws together important papers that show how Age and Ageing is helping to shape and grow care-home research. The   collection outlines the technical issues that researchers face by grouping together important feasibility trials conducted in the sector. It looks at the challenges of measuring quality of life and working with routine data in care homes. It brings together observational studies considering loneliness, functional dependency, stroke outcomes, prescribing and acute deterioration. Health services research in care homes is represented by two studies that demonstrate realist evaluation as a way to make sense of service innovations. Papers are included that consider: non-pharmacological strategies for residents with dementia, end-of-life care, sexuality and intimacy and the care-home workforce. Given the importance of the COVID-19 pandemic in care homes, all of the care home COVID-19 papers published in Age and Ageing to date are included. Finally, a group of papers that present innovative approaches to research in care homes, each of which give voice to residents and/or staff, are collated and presented as a way of moving towards a more resident and care home centred research agenda.

Since the initial reports that a group of small RNAs, now known as microRNAs (miRNAs), regulates gene expression without being translated into proteins, there has been an explosion of studies on these important expression modulators.Drosophila melanogasterhas proven to be one of the most amenable animal models for investigations of miRNA biogenesis and gene regulatory activities. Here, we highlight the publicly available genetic tools and strategies forin vivofunctional studies of miRNA activity inD. melanogaster. By coupling genetic approaches using available strain libraries with technologies for miRNA expression analysis and target and pathway prediction, researchers' ability to test functional activities of miRNAsin vivois now greatly enhanced. We also comment on the tools that need to be developed to aid in comprehensive evaluation ofDrosophilamiRNA activities that impact traits of interest. [ABSTRACT FROM PUBLISHER]

Sexual traits convey information about individual quality to potential mates. Environmental and genetic factors affect sexual trait expression and perception via effects on animal condition and health. High fat diet (HFD) is one environmental factor that adversely affects Drosophila melanogaster health, and its effects on animal health are mediated through conserved metabolic signaling pathways. HFD decreases female attractiveness, resulting in reduced male mating behaviors toward HFD females. HFD also affects the ability of males to judge mate attractiveness and likely alters fly condition and sexual traits to impact mating behavior. Here we show that HFD affects both visual (body size) and non-visual (pheromone profiles) sexual traits, which likely contribute to decreased fly attractiveness. We also demonstrate that adult-specific HFD effects on male mate preference can be rescued by changing metabolic signaling. These results demonstrate that HFD alters Drosophila sexual cues to reflect concurrent effects on condition and that less severe behavioral defects can be reversed by genetic manipulations that rescue fly health. This work expands on current knowledge of the role that metabolic signaling pathways play in linking animal health, sexual traits, and mating behavior, and provides a robust assay in a genetically tractable system to continue examining these processes.
