Summary: This study systematically reviewed the evidence on the acute and chronic effects of grape interventions on cognition and mood. Chronic studies found improvements in some cognitive domains, while acute studies showed no consistent effect on memory but improvements in reaction time. However, differences in study design, dosages, and outcome tests hindered between-study comparison. Overall, the results suggest that grapes can enhance certain aspects of cognition after both acute and chronic interventions.

Summary: Cognitive and mood changes are commonly experienced before, during and after menopausal transition, which are associated with the effects of estrogen on the brain. Although hormone treatment may alleviate these psychological issues, the evidence for long-term benefits is inconclusive. Personalized hormone therapy should be considered for women with severe menopausal complaints.

Summary: The study found a strong association between body fat mass and glucose homeostasis, while dietary macronutrients showed no significant impact. The area under the glucose curve (AUC) was significantly correlated with fasting insulin levels, suggesting a role of endocrine hormones in glucose metabolism. Genes identified through transcriptomic analysis may play crucial roles in glucose homeostasis, highlighting previously unexpected mechanisms.

Summary: This study investigated the effects of low and moderate doses of coffeeberry extract on cognition and mood. The results showed that 100 mg of coffeeberry extract resulted in increased mental fatigue and decreased accuracy on a task of sustained attention. However, no significant effects were found with 300 mg of coffeeberry extract. Therefore, low to moderate doses of coffeeberry extract do not have a beneficial effect on mood, mental and physical energy levels, or cognition.

Summary: Previous studies have shown that the retrieval of positive involuntary autobiographical memories can improve negative mood, but these studies did not control the cues associated with memory retrieval and were not experimentally proven. This study selected appropriate cue words and experimentally demonstrated the mood repair effect of positive involuntary autobiographical memory retrieval among Japanese adults.

Summary: This systematic review and meta-analysis examined the impact of walnut intake on cognitive decline and risk factors. While there were significant associations between walnut intake and cognition-related outcomes, no effects were seen on glucose homeostasis or inflammation. Further high-quality studies are needed to clarify the role of walnuts in cognitive health.

Summary: Genetically predicted high fat mass and fat percentage significantly increased risks of most cardiometabolic diseases, while high fat-free mass had protective effects on most cardiometabolic diseases after accounting for fat mass. Fat mass, fat-free mass, and fat percentage were all positively associated with higher risks of atrial fibrillation and flutter, varicose veins, and deep vein thrombosis and pulmonary embolism.

Summary: This systematic review investigated the relationship between dietary patterns in healthy middle-aged adults and neurocognition both in middle age and later in life. The findings were mixed, with some studies reporting a significant positive relationship between adherence to various healthy dietary patterns and neurocognition, but others reporting no such relationship. However, the review suggests that adherence to the Mediterranean diet and other healthy dietary patterns in middle age can protect neurocognition later in life.

Summary: Food insecurity is associated with higher BMI, likely due to distress and using food as coping mechanism. A study on adults in the UK during the first COVID-19 lockdown found that pandemic-related food insecurity indirectly influenced changes in weight promoting eating behaviors. Food insecurity was associated with distress, which in turn was associated with eating as a way of coping and increases in weight promoting eating behaviors. Food insecurity also indirectly influenced diet quality through distress. These findings strengthen the evidence that distress and eating to cope are generic mediators of food insecurity and eating behavior.

Summary: This study investigated the effects of alcohol hangover on attentional resources, delayed memory recognition, and the interaction between attentional load and hangover. The results showed that alcohol hangover reduced recognition accuracy, increased tracking costs, and led to higher ratings of mental demand, effort, and frustration. The study also found that attentional load had a significant effect on recognition accuracy and response time.

Summary: This study compares alcohol consumption during the heaviest drinking occasion before and during the first COVID-19 lockdown in the Netherlands. It finds a significant reduction in alcohol intake, drinking duration, subjective intoxication, and hangover severity during the lockdown. The frequency of alcohol hangovers also decreased. Gender and age differences were observed, with men consuming more alcohol and experiencing more hangovers, and young adults reducing their alcohol intake and reporting lower hangover severity during the lockdown.

Summary: This study examined the effects of a multinutrient formula on memory, attention, mood, and nutrient status in middle-aged adults. The results showed that the formula was associated with increased B vitamin status, but did not significantly improve memory and attention in the whole cohort. Interestingly, there was a beneficial effect of supplementation on attentional performance in individuals with an 'optimal' diet prior to supplementation.

Summary: The use of ?-3 PUFA supplements to support cognitive health is common among middle-aged and older adults. However, few studies have explored the cognitive effects of ?-3 PUFA in middle-aged adults, particularly the acute effects. This study found no significant difference in cognitive performance but observed a reduction in aortic systolic blood pressure following ?-3 PUFA consumption. Future replication should include females and patients with hypertension.

Summary: There is no effective treatment for reducing the severity and duration of a common cold episode. However, SJP-002 (naproxen and fexofenadine) can reduce symptom severity by two-thirds and the duration of the episode by approximately half. The common cold is a frequently experienced immune-related complaint, and current available treatments have limited efficacy.

Summary: The alcohol hangover refers to the combination of negative mental and physical symptoms experienced after alcohol consumption. This study compared the next-day effects of alcohol consumption between hangover-resistant and hangover-sensitive drinkers, finding that hangover-sensitive drinkers experienced symptoms such as sleepiness, fatigue, concentration problems, and headache that gradually decreased throughout the day. Hangover-resistant drinkers, however, reported the absence of a hangover, except for increased fatigue and reduced vigor. The study highlights the differences in next-day effects between individuals who are more or less susceptible to alcohol hangovers.
