    t the cortical tracking of background speech rhythms plays a functional role in speech processing.Control of protein intake is essential for numerous biological processes as several amino acids cannot be synthesized de novo, however, its neurobiological substrates are still poorly understood. In the present study, we combined in vivo fiber photometry with nutrient-conditioned flavor in a rat model of protein appetite to record neuronal activity in the VTA, a central brain region for the control of food-related processes. In adult male rats, protein restriction increased preference for casein (protein) over maltodextrin (carbohydrate). Moreover, protein consumption was associated with a greater VTA response, relative to carbohydrate. After initial nutrient preference, a switch from a normal balanced diet to protein restriction induced rapid development of protein preference but required extensive exposure to macronutrient solutions to induce elevated VTA responses to casein. Furthermore, prior protein restriction induced long-lasting food preference and VTA responses. This study reveals that VTA circuits are involved in protein appetite in times of need, a crucial process for animals to acquire an adequate amount of protein in their diet.SIGNIFICANCE STATEMENT Acquiring insufficient protein in one’s diet has severe consequences for health and ultimately will lead to death. In addition, a low level of dietary protein has been proposed as a driver of obesity as it can leverage up intake of fat and carbohydrate. However, much remains unknown about the role of the brain in ensuring adequate intake of protein. Here, we show that in a state of protein restriction a key node in brain reward circuitry, the VTA, is activated more strongly during consumption of protein than carbohydrate. Moreover, although rats’ behavior changed to reflect new protein status, patterns of neural activity were more persistent and only loosely linked to protein status.Cholinergic regulation of hippocampal circuit activity has been an active area of neurophysiological research for decades. The prominent cholinergic innervation of intrinsic hippocampal circuitry, potent effects of cholinomimetic drugs, and behavioral responses to cholinergic modulation of hippocampal circuitry have driven investigators to discover diverse cellular actions of acetylcholine in distinct sites within hippocampal circuitry. Further research has illuminated how these actions organize circuit activity to optimize encoding of new information, promote consolidation, and coordinate this with recall of prior memories. The development of the hippocampal slice preparation was a major advance that accelerated knowledge of how hippocampal circuits functioned and how acetylcholine modulated these circuits. Using this preparation in the early 1980s, we made a serendipitous finding of a novel presynaptic inhibitory effect of acetylcholine on Schaffer collaterals, the projections from CA3 pyramidal neurons to dendrites of CA1 pyramidal cells. CCT245737 order We characterized this effect at cellular and pharmacological levels, published the findings in the first volume of the Journal of Neuroscience, and proceeded to pursue other scientific directions. We were surprised and thrilled to see that, nearly 40 years later, the paper is still being cited and downloaded because the data became an integral piece of the foundation of the science of cholinergic regulation of hippocampal function in learning and memory. This Progressions article is a story of how single laboratory findings evolve through time to be confirmed, challenged, and reinterpreted by other laboratories to eventually become part of the basis of fundamental concepts related to important brain functions.Many Americans fail to get life-saving vaccines each year, and the availability of a vaccine for COVID-19 makes the challenge of encouraging vaccination more urgent than ever. We present a large field experiment (N = 47,306) testing 19 nudges delivered to patients via text message and designed to boost adoption of the influenza vaccine. Our findings suggest that text messages sent prior to a primary care visit can boost vaccination rates by an average of 5%. Overall, interventions performed better when they were 1) framed as reminders to get flu shots that were already reserved for the patient and 2) congruent with the sort of communications patients expected to receive from their healthcare provider (i.e., not surprising, casual, or interactive). The best-performing intervention in our study reminded patients twice to get their flu shot at their upcoming doctor’s appointment and indicated it was reserved for them. This successful script could be used as a template for campaigns to encourage the adoption of life-saving vaccines, including against COVID-19.Homelessness is associated with significant psychosocial and health disparities. The rate of epilepsy among this cohort is eight times greater than that in the settled population, and the associated morbidity is higher due to lack of integrated care, difficulties with treatment adherence, substance abuse and poor social circumstances. There is a high rate of seizure-related death in homeless patients. Seizures are one of the most common neurological cause for emergency department presentation among this population. The aim of this quality improvement project was to use a multistakeholder co-production approach to design a new pathway of care for homeless patients with epilepsy to improve access to specialist epilepsy care and to strengthen the links between hospital and community teams who manage this population. After several years of observation, stakeholder engagement and numerous tests of change, we have created a new care pathway and developed bespoke tools for primary care providers and for physicians working in the emergency department to enable them to assess and manage patients as they present, as well as provide access to remote epilepsy specialist support.

    Risk-adjusted rates of hospital readmission are a common indicator of hospital performance. There are concerns that current risk-adjustment methods do not account for the many factors outside the hospital setting that can affect readmission rates. Not accounting for these external factors could result in hospitals being unfairly penalized when they discharge patients to communities that are less able to support care transitions and disease management. While incorporating adjustments for the myriad of social and economic factors outside of the hospital setting could improve the accuracy of readmission rates as a performance measure, doing so has limited feasibility due to the number of potential variables and the paucity of data to measure them. This paper assesses a practical approach to addressing this problem using mixed-effect regression models to estimate case-mix adjusted risk of readmission by community of patients’ residence (community risk of readmission) as a complementary performance indicator to arge planning, reduce penalties to hospitals, and most importantly, provide higher quality care to the people that they serve.This quality improvement project began when physicians and nurses at our hospital observed patients waiting for excessive periods of time for a porter to escort patients from the emergency department (ED) to medical imaging (MI). However, certain patients may not need staff escort and are able to ambulate from ED to MI by themselves. This would reduce waiting time from when the X-ray is ordered to X-ray being done, which may reduce overall ED length of stay and improve patients’ experience.Our project aim is to decrease the time to X-ray by 50% within 6 months by having appropriate ambulatory patients walk from the ED to the X-ray department without a porter. To achieve our goal, several strategies were employed. First, brainstorm sessions were held to better understand the barriers and ways to implement the new process. Second, a patient survey was conducted to understand their thoughts on the change idea. Third, data were collected to assess the inefficiency problem on the number of times non-porter staff escorted patients due to porters being unavailable. A total of 14 PDSA (Plan-Do-Study-Act) cycles were completed between December 2018 and May 2019. A human factor specialist was consulted to examine the process for safety and optimisation of the patient journey.In our PDSA cycles, self-ambulatory patients were compared with ambulatory patients who required an escort. An improvement was found from time to X-ray of 28 min (11 min vs 39 min). The new self-ambulatory process was implemented in June 2019 on a daily basis.

    Children with medical complexity (CMC) are commonly assisted by medical devices, which family caregivers are responsible for managing and troubleshooting in the home. Optimizing device use by maximizing the benefits and minimizing the complications is a critical goal for CMC but is relatively unexplored. In this study, we sought to identify and describe workarounds families have developed to optimize medical device use for their needs.

    We conducted 30 contextual inquiry interviews with families of CMC in homes. Interviews were recorded, transcribed, and analyzed for barriers and workarounds specific to medical device usage through a directed content analysis. We used observation notes and photographs to confirm and elaborate on interview findings.

    We identified 4 barriers to using medical devices in the home (1) the quantity and type of devices allotted do not meet family needs, (2) the device is not designed to be used in locations families require, (3) device use is physically or organizationally disruptive to the home, and (4) the device is not designed to fit the user. We also identified 11 categories of workarounds to the barriers.

    Families face many barriers in using medical devices to care for CMC. Our findings offer rich narrative and photographic data revealing the ways in which caregivers work around these barriers. Future researchers should explore the downstream effects of these ubiquitous, necessary workarounds on CMC outcomes toward developing interventions that optimize device use for families.

Risk factors for the development of SCC include infection with human papillomavirus (HPV), tobacco use, and alcohol use. HPV-positive SCC of the oral cavity is more commonly seen in young adult patients, whereas HPV-negative disease is more prevalent in older patients with histories of alcohol and tobacco use. We describe the case of a young adult with an extensive history of vaping using nicotine-delivery systems who was diagnosed with HPV-negative SCC that was rapidly progressive and fatal.

    Non-adherence to anti-infective therapy contributes to treatment failure and the emergence of bacterial resistance. This study aimed to assess at-home adherence, by paediatric patients, to oral anti-infective (OAI) therapy prescribed for treatment of acute infections and to explore the factors contributing to non-adherence.

    This prospective descriptive study involved French-speaking patients under 16 years of age who were discharged with one or more OAIs prescribed for home administration for a maximum of 30 days. Telephone surveys were used to assess overall adherence, which consisted of primary adherence (patient’s ability to procure the medication) and secondary adherence (patient’s ability to take the treatment as prescribed).

    Overall, 51.7% (30/58) of patients were adherent to OAI therapy, with 100% primary adherence (n=69/69) and 51.7% secondary adherence (n=30/58). On average, patients took 98% of the total number of doses prescribed, and non-adherence was related mostly to not following medication administration schedules (63.
