Summary: Pigs reared in tropical climate areas are affected by high ambient temperatures, leading to changes in feeding behavior and reduced performance. The study investigated the effects of cyclic heat stress (CHS) and light events on pig feeding behavior. Results showed that CHS disrupted the feeding circadian rhythm, and pigs prioritized feed intake during the coolest hours of the day. However, nocturnal cooling did not fully compensate for the reduced meal size caused by CHS. The lighting program also influenced feeding patterns, increasing or decreasing meal size when the lights were turned on or off.

Summary: Several brain areas participate in thirst and fluid intake control, but the interaction and specific roles of these circuits are not fully understood. This study investigates the effect of central GLP-1 receptor activation on water intake. It suggests that the PVH is a site of action for GLP-1 receptor activation in the inhibition of water intake, but a counterbalancing pathway may exist.

Summary: During endurance exercise, both dehydration and overhydration can negatively impact performance and health. While minor dehydration or overhydration may not have significant effects, moderate to severe levels can greatly reduce performance and increase the risk of illness. Therefore, athletes should carefully consider the recommendations provided in the review article to choose the rehydration method that best balances hydration levels and optimizes physical performance.

Summary: This case report describes the clinical findings, MRI, and necropsy results of a Belted Galloway heifer with severe dehydration and hypernatremia, but concurrent adipsia and isosthenuria. The postmortem examination revealed a complex forebrain malformation that may be involved in the development of hypernatremia and adipsia in bovines.

Summary: Accumulative evidence suggests that meal timing is associated with cardiometabolic risks by affecting circadian rhythms. However, the evidence is not clear. This cross-sectional study aimed to investigate the relationship between nightly fasting duration, meal timing, and frequency, and metabolic syndrome (MetS) in Iranian adults. The results showed that longer nightly fasting duration was associated with a lower risk of MetS and elevated TAG, while the energy intake of the first and last meal did not have a significant connection with MetS. These findings suggest that time-related eating patterns may play a role in cardiometabolic risks in Iranian adults.

Summary: Eating at night can lead to an increase in triglyceride levels, which may contribute to the dyslipidemia and elevated cardiovascular disease risk observed in shift workers. This time-of-day dependency on postprandial lipid metabolism highlights the importance of meal timing in maintaining a healthy lipid profile.

Summary: This study suggests that the human circadian system can anticipate large meals. It also demonstrates that the timing of a three-meal daily feeding pattern can synchronize with circadian rhythms. Furthermore, the research shows that glucose concentrations decrease before the first meal and hunger increases before the predicted meal times in the large meal group.

Summary: Eating and drinking are controlled by similar mechanisms, making it hard to study the control of fluid intake specifically. Glucagon-like peptide-1 (GLP-1) is involved in the control of both behaviors, but its role in fluid intake is not well understood. This study proposes using Brattleboro rats, a model of excessive water intake, to study the central controls of food and fluid intakes. The results suggest that Brattleboro rats have a selective disruption in GLP-1's control of water intake.

Summary: Nutritional rehabilitation with naso-gastric feeding (NGF) is crucial for weight restoration in hospitalized anorexia nervosa (AN) patients. Patients treated with NGF have a lower BMI on admission and discharge, longer hospital stay, and a longer time to relapse compared to patients without NGF. Early NGF intervention is associated with a shorter length of hospitalization and facilitates faster recovery.

Summary: The terms "drinking to thirst" and "ad libitum drinking" can be used interchangeably, but they have different effects on drinking patterns during exercise. Drinking according to thirst leads to higher perception of thirst and volume consumed per sip, and lower total number of sips compared to ad libitum drinking. There were also minor differences in perceived exertion, rectal temperature, and heart rate between the two methods. However, both methods equally maintain fluid balance during prolonged exercise.

Summary: The study investigated the roles of the circadian clock and feeding rhythms in regulating rhythmic gene expression in the liver, highlighting their importance and differential contributions. Both feeding patterns and the circadian clock influence gene expression rhythms, with distinct amplitudes. By analyzing multiple core clock regulators, the research revealed their varying impacts on liver gene expression regulation.

Summary: This study reveals the neural mechanism of secretin in managing thirst in the central nervous system. The results demonstrate that the local ablation of SCT receptor (SCTR) in the subfornical organ (SFO) reduces water intake in dehydrated mice, while salt intake remains unaffected. Furthermore, it is found that SCT elicits inward currents in the neuronal nitric oxide synthase (SFOnNOS) neurons via SCTR in the presence of glutamate receptor antagonists.

Summary: The ability of amylin to inhibit food intake is reduced under hypoglycemic conditions, possibly due to the co-sensitivity of AP neurons to amylin and glucose. Amylin can also buffer meal-induced glucose appearance at EU and HYPO levels.

Summary: There is evidence to suggest that chronic stress impacts neurochemical homeostasis and contributes to mental disorders. This study investigates the therapeutic potential of p-coumaric acid (p-CA), a natural compound found in vegetables and fruits, against stress-associated mental disorders. The findings suggest that p-CA could alleviate cognitive deficits and depression-like behavior in mice exposed to chronic restraint stress (CRS) by regulating the PKA-CREB-BDNF signaling pathway.

The results suggest that a combination of acute and chronic J147 treatment may be optimal for treatment.

Summary: This study examined sleep, sleep/wake regularity, and cognition in college students diagnosed with depression and using serotonergic antidepressants, comparing them to those without a depression diagnosis. The results showed that students using antidepressants had slightly longer wake after sleep onset and lower sleep efficiency, but these differences were likely not noticed by the participants. There were no differences in sleep regularity or cognition between the two groups.

Summary: Social stress plays a significant role in the development of neuropsychiatric disorders and can lead to behavioral deficits such as social withdrawal. This study investigates the impact of social stress on social reward in Syrian hamsters. The results show that subordinate and socially defeated males have reduced motivation for social interactions compared to dominant males. Additionally, winning males exhibit greater activation in the mesolimbic dopamine system compared to losers. In females, there were no differences in social entries between winners and losers, but winning females display more activation in the NAc shell.

The findings showed a positive correlation between BMI and stress, anxiety, and depression. These results suggest that reducing body fat accumulation may contribute to improving mental health in individuals with SUD during recovery.

Summary: This PROSPERO pre-registered systematic review and meta-analysis evaluated the olfactory and gustatory changes in pregnant individuals. The meta-analysis revealed that pregnant individuals performed poorer in odour identification, rated olfactory stimuli to be more intense during the second and third trimester, and had increased pleasantness for sweet taste in the first trimester. No major difference was observed in terms of gustatory functions between pregnant and non-pregnant subjects.
