Food intake behavior is regulated by a network of appetite-inducing and appetite-suppressing neuronal populations throughout the brain. The parasubthalamic nucleus (PSTN), a relatively unexplored population of neurons in the posterior hypothalamus, has been hypothesized to regulate appetite due to its connectivity with other anorexigenic neuronal populations and because these neurons express Fos, a marker of neuronal activation, following a meal. However, the individual cell types that make up the PSTN are not well characterized, nor are their functional roles in food intake behavior. Here, we identify and distinguish between two discrete PSTN subpopulations, those that express tachykinin-1 (PSTNTac1 neurons) and those that express corticotropin-releasing hormone (PSTNCRH neurons), and use a panel of genetically encoded tools in mice to show that PSTNTac1 neurons play an important role in appetite suppression. Both subpopulations increase activity following a meal and in response to administration of the anorexigenic hormones amylin, cholecystokinin (CCK), and peptide YY (PYY). Interestingly, chemogenetic inhibition of PSTNTac1, but not PSTNCRH neurons, reduces the appetite-suppressing effects of these hormones. Consistently, optogenetic and chemogenetic stimulation of PSTNTac1 neurons, but not PSTNCRH neurons, reduces food intake in hungry mice. PSTNTac1 and PSTNCRH neurons project to distinct downstream brain regions, and stimulation of PSTNTac1 projections to individual anorexigenic populations reduces food consumption. Taken together, these results reveal the functional properties and projection patterns of distinct PSTN cell types and demonstrate an anorexigenic role for PSTNTac1 neurons in the hormonal and central regulation of appetite.
Mood disorders are burdensome illnesses that often go undetected and untreated. Sensor technologies within smartphones may provide an opportunity for identifying the early changes in circadian rhythm and social support/connectedness that signify the onset of a depressive or manic episode.

Using smartphone sensor data, this study investigated the relationship between circadian rhythm, which was determined by GPS data, and symptoms of mental health among a clinical sample of adults diagnosed with major depressive disorder or bipolar disorder.

A total of 121 participants were recruited from a clinical setting to take part in a 10-week observational study. Self-report questionnaires for mental health outcomes, social support, social connectedness, and quality of life were assessed at 6 time points throughout the study period. Participants consented to passively sharing their smartphone GPS data for the duration of the study. Circadian rhythm (ie, regularity of location changes in a 24-hour rhythm) was extrain anxiety in a clinical sample of adults with mood disorders. Larger studies are required for further validations. However, smartphone sensing may have the potential to monitor early symptoms of mood disorders.
The purpose of this study was to compare the efficacy of a single dose of dexamethasone to 2 doses of dexamethasone in treating mild to moderate asthma exacerbations in pediatric patients. We anticipated that there would not be a difference in the rate of return visits to the emergency department (ED), urgent care, or primary care physician for continued asthma symptoms.

This was a prospective, randomized, single-center, unblinded, parallel-group randomized clinical trial of patients 2 to 20 years old presenting to a pediatric ED with mild to moderate asthma exacerbations. The patients were randomized to receive 1 or 2 doses of dexamethasone (0.6 mg/kg per dose, maximum of 16 mg). OTUB2-IN-1 Telephone follow-up interviews were performed on the sixth day after ED visit. The primary outcome measures were return visits to either primary care physician or ED for continued asthma symptoms. Secondary outcomes were days of symptoms, missed school days, and adverse effects.

Of the 318 children initially enrolled, 308 patiof return visits for continued or worsened symptoms between patients randomized to 1 or 2 doses of dexamethasone.This paper overviews the final remarks lecture delivered (by K. D. K.) at the end of this bioinorganic chemistry Faraday Discussion, held online for a worldwide audience from January 31 - February 3, 2022. This paper provides discussion in six sections (1) the Introductory lecture, from Ed Solomon, emphasized past and present uses of advanced spectroscopic methods and theoretical approaches to elucidate metalloenzyme active site structure, physical properties and function. (2) The discussion topics are divided into groups having similar research themes, as seen from this author's perspective. Emphasis is given to the non-heme iron group of articles with dioxygen activation research. (3) Small molecule activation (e.g., N2, CO2 and O2 reduction; CH4 or H2O oxidation) is widely covered in this discussion; this authors' view of the important reactions in bioinorganic chemistry is discussed. (4) We discuss current practice and vision for employing materials chemistry to widely apply to electrocatalytic methods to effect small molecule activation (as above) to fulfill societal energy demands. (5) A discussion is given on the topic of synthetic models and the approach utilized therein. (6) New research on the authors' synthetic modeling is presented; preliminary results are given in the area of copper mediated peroxide activation.
Understanding the factors causing nonurgent visits to the pediatric emergency departments (PED) is essential for developing effective interventions. Sociodemographic factors might have a direct effect, or they might be associated with other potential causal factors such as access, perceived severity, and convenience. Therefore, we aimed to evaluate the factors that might have an effect on nonurgent PED visits and parental overestimation of emergency severity.

Data of a total of 974 patients who have been administered to the PED of a district state hospital were collected with a cross-sectional, self-administered survey. Level 5 was accepted as nonurgent cases according to the Pediatric Canadian Triage and Acuity Scale. Parents' assessment of their child's emergency status was assessed along with the age and sex of the child, the number of children, presence of a chronic illness, presence of fever, admission time, parental age, education status and occupation, transportation method, and living distance to gent visits constitute most of the PED admissions. Several factors were found to be associated with nonurgent visits either by causing a direct effect or by indirectly impacting the perceived severity. Health literacy-based interventions targeting common symptoms like fever and especially younger parent groups might be beneficial in lowering the patient burden of PEDs.
This study aimed to identify motivating factors in why parents administer imported medications to their children.

In this qualitative study, we enrolled caregivers of patients younger than 18 years who presented for care at a pediatric emergency department. The study team conducted face-to-face interviews with caregivers in the emergency department and used a semistructured question guide to probe for themes regarding the use of imported medications in children. Interviews were recorded, transcribed, translated if necessary, and coded. We applied grounded theory methodology to assess for themes and adapted the Andersen model of health care utilization to provide a framework for the identified themes.

We completed 30 interviews, 9 of which were conducted in Spanish. Themes surrounding imported medication usage were categorized into predisposing, enabling, and need factors. Predisposing factors included perception that an ill child needs medication to get better, perception of medication quality, and pastics.Chronic pruritus is a prominent symptom of allergic contact dermatitis (ACD) and represent a huge unmet health problem. However, its underlying cellular and molecular mechanisms remain largely unexplored. TRPC3 is highly expressed in primary sensory neurons and has been implicated in peripheral sensitization induced by proinflammatory mediators. Yet, the role of TRPC3 in acute and chronic itch is still not well defined. Here, we show that, among mouse trigeminal ganglion (TG) neurons, Trpc3 mRNA is predominantly expressed in nonpeptidergic small diameter TG neurons of mice. Moreover, Trpc3 mRNA signal was present in the majority of presumptively itch sensing neurons. TRPC3 agonism induced TG neuronal activation and acute nonhistaminergic itch- and pain-like behaviors in naïve mice. In addition, genetic deletion of Trpc3 attenuated acute itch evoked by certain common nonhistaminergic pruritogens, including endothelin-1 and SLIGRL-NH2. In a murine model of contact hypersensitivity (CHS), Trpc3 mRNA expression level and function were upregulated in the TG following CHS. Pharmacological inhibition and global knockout of Trpc3 significantly alleviated spontaneous scratching behaviors without affecting concurrent cutaneous inflammation in the CHS model. Furthermore, conditional deletion of Trpc3 in primary sensory neurons but not in keratinocytes produced similar antipruritic effects in this model. These findings suggest that TRPC3 expressed in primary sensory neurons may contribute to acute and chronic itch via a histamine independent mechanism and that targeting neuronal TRPC3 might benefit the treatment of chronic itch associated with ACD and other inflammatory skin disorders.Total knee arthroplasty (TKA) is effective for pain reduction in most patients, but 15% or more report unsatisfactory long-term pain outcomes. We tested whether oxidative stress (OS) related to extended tourniquet application during TKA and subsequent ischemic reperfusion contributed to adverse post-TKA pain outcomes. Blood samples were obtained in 91 osteoarthritis patients (63% female) undergoing TKA prior to tourniquet placement (T1), 45 minutes after tourniquet inflation (T2), and 15 minutes following tourniquet removal (T3). Plasma levels of F2-isoprostanes and isofurans, the most specific measures of in vivo OS, were quantified. Pain intensity and function were assessed at baseline and again at 6 weeks and 6 months following TKA. Results indicated that higher Combined OS (F2-isoprostanes+Isofurans/2) at T1 baseline as well as larger increases in Combined OS from T1 to T2 were associated with higher baseline-corrected past 24-hour worst and average pain intensity (numeric rating scale) and higher past week McGill Pain Questionnaire-2 total scores at 6-month follow-up (p's less then .05). Increases in Combined OS from T1 to T3, which should most directly capture OS and ischemic reperfusion injury related to tourniquet use, were not associated with short-term or long-term post-TKA pain outcomes. Longer ischemia duration was unexpectedly associated with lower baseline-corrected pain intensity at 6-month follow-up. Combined OS was not linked to functional outcomes at either follow-up. Elevated perioperative OS appears to exert small but significant adverse effects on long-term post-TKA pain outcomes, although this OS appears unrelated to ischemic reperfusion injury associated with extended tourniquet use.
