er follow-up to evaluate the long-term impact on weight loss and comorbidities.
Nausea is a common complaint among children and is particularly prevalent in children with functional abdominal pain (FAP), with nearly half of children with FAP also endorsing nausea. Dysfunction of the autonomic nervous system, which can be indexed by heart rate variability (HRV), leads to abnormalities in gastric electrical activity that are associated with GI symptoms.
To evaluate that relationship between nausea severity and HRV in adolescents and young adults with a history of FAP and to assess for sex differences.
Participants were pediatric patients with a diagnosis of FAP who were recruited from a pediatric GI clinic between 1993 and 2007 for a prospective study of the course of FAP. Study analyses focused on the cross-sectional relationship between HRV, indexed by standard deviation of the R-R interval (SDRRI) and high-frequency (HF) power, and nausea severity collected during a follow-up visit in late adolescence and young adulthood.
Controlling for age and BMI, a significant nausea by sex interaction emerged for both SDRRI and HF power. Tests of conditional effects of nausea by sex showed that the inverse relation between nausea severity and both SDRRI and HF was significant for females but not for males.
This is the first study to evaluate the relationship between nausea severity and HRV. Greater nausea severity was associated with lower HRV in females but not in males. Further validation of these results may provide insight into novel treatment approaches for females with nausea that target vagal tone.

Preliminary studies were conducted to optimize the parameters of light and acoustic prepulse inhibition of ASR and TSR. Once these parameters were set, a new group of rats was administered PRM (0 or 90 mg/kg) or DLM (0 or 25 mg/kg) by gavage in 5 mL/kg corn oil. ASR and TSR were assessed using acoustic or light prepulses 6, 8, and 12 h after PRM and 2, 4, and 6 h after DLM exposure. PRM increased ASR 6 h post-treatment with no interaction with acoustic prepulse levels and with no effect on TSR. When light was used as the prepulse, PRM increased ASR and TSR at 6 h with no interaction with prepulse levels. DLM decreased ASR and TSR on trials without prepulses but not on trials with acoustic prepulses. DLM also decreased ASR when light prepulses were present 4 h post-treatment. A final experiment assessed whether the house light in the test cabinet affected ASR and TSR after PRM or DLM exposure. Rats had increased ASR and TSR when house lights were on compared with when they were off, but lighting did not differentially interact with PRM or DLM. Light and acoustic prepulses of ASR and TSR have different effects depending on the test agent and the test parameters.Despite recent research on joint motion measurement to monitor human body movement, current measurement techniques and tools have significant limitations, including requiring large space for measurement and causing discomfort in test subjects wearing motion sensors. Our study aims, first, to develop carbon nanotube (CNT)-based textile joint motion sensors. Second, ours study aims to identify the most suitable CNT-based sensor structure and attachment method for use on a wearable platform during general exercise speeds. Lastly, we used these sensors on the human body, using sleeves and legs to find the most stable location, and we used the CNT-based sensor condition to monitor joint motions. Selleckchem 4-Aminobutyric We utilized our CNT-based sensor, which has proper elasticity as well as conductivity, and applied it to the elbow and knee joints. Based on the strain gauge principle, we monitored the variance of electric resistance that occurred when the CNT-based sensor was stretched due to limb motion. Our study tested 48 types of sensors. These sensors were applied to the CNT using different base knit textiles as well as different attachment methods, layers, sensor lengths, and sensor widths. The four most successful sensor types, which showed superior efficacy over the others in joint motion measurement, were selected for further study. These four sensors were then used to measure the elbow and knee joint motions of human subjects by placing them on different locations on sleeves and legs. The CNT knit textile sensors best suited to measuring joint motions are those with a double-layered CNT knit and 5 cm long × 0.5 cm or 1 cm wide sensors attached to a polyester¬-based knit using a welding method. The best position for the sensor to more stably monitor joint motions was the "below hinge position" from the elbow or knee hinge joint. Our study suggests an alternative strategy for joint-motion measurement that could contribute to the development of more comfortable and human-friendly methods of human limb motion measurement.
Ubrogepant is an oral, small-molecule calcitonin gene-related peptide receptor antagonist approved for the acute treatment of migraine. The efficacy and safety of ubrogepant were demonstrated in two pivotal phase 3, single-attack, randomized, placebo-controlled trials (ACHIEVE I and ACHIEVE II).
We conducted a post hoc analysis of pooled data from the ACHIEVE trials to evaluate the efficacy, safety, and tolerability of ubrogepant 50mg (the only dose evaluated in both trials) versus placebo across a large population of participants with migraine. The coprimary efficacy outcomes were pain freedom and absence of the most bothersome migraine-associated symptom (including photophobia, phonophobia, and nausea) at 2h post dose. Secondary outcomes included pain relief at 2h post dose, sustained pain relief and pain freedom from 2 to 24h, and absence of specific migraine-associated symptoms at 2h post dose.
A total of 2240 eligible participants were randomized to placebo (n = 1122) or ubrogepant 50mg (n = 1118) in the ACHIEVE trials.
