The Acute and Chronic Cognitive Effects of a Sage Extract: A Randomized, Placebo Controlled Study in Healthy Humans.

The sage (Salvia) plant contains a host of terpenes and phenolics which interact with mechanisms pertinent to brain function and improve aspects of cognitive performance. However, previous studies in humans have looked at these phytochemicals in isolation and following acute consumption only. A preclinical in vivo study in rodents, however, has demonstrated improved cognitive outcomes following 2-week consumption of CogniviaTM, a proprietary extract of both Salvia officinalis polyphenols and Salvia lavandulaefolia terpenoids, suggesting that a combination of phytochemicals from sage might be more efficacious over a longer period of time. The current study investigated the impact of this sage combination on cognitive functions in humans with acute and chronic outcomes. Participants (n = 94, 25 M, 69 F, 30-60 years old) took part in this randomised, double-blind, placebo-controlled, parallel groups design where a comprehensive array of cognitions were assessed 120- and 240-min post-dose acutely and following 29-day supplementation with either 600 mg of the sage combination or placebo. A consistent, significant benefit of the sage combination was observed throughout working memory and accuracy task outcome measures (specifically on the Corsi Blocks, Numeric Working Memory, and Name to Face Recall tasks) both acutely (i.e., changes within day 1 and day 29) and chronically (i.e., changes between day 1 to day 29). These results fall slightly outside of those reported previously with single Salvia administration, and therefore, a follow-up study with the single and combined extracts is required to confirm how these effects differ within the same cohort.

Sensitivity to Experiencing Alcohol Hangovers: Reconsideration of the 0.11% Blood Alcohol Concentration (BAC) Threshold for Having a Hangover.

The 2010 Alcohol Hangover Research Group consensus paper defined a cutoff blood alcohol concentration (BAC) of 0.11% as a toxicological threshold indicating that sufficient alcohol had been consumed to develop a hangover. The cutoff was based on previous research and applied mostly in studies comprising student samples. Previously, we showed that sensitivity to hangovers depends on (estimated) BAC during acute intoxication, with a greater percentage of drinkers reporting hangovers at higher BAC levels. However, a substantial number of participants also reported hangovers at comparatively lower BAC levels. This calls the suitability of the 0.11% threshold into question. Recent research has shown that subjective intoxication, i.e., the level of severity of reported drunkenness, and not BAC, is the most important determinant of hangover severity. Non-student samples often have a much lower alcohol intake compared to student samples, and overall BACs often remain below 0.11%. Despite these lower BACs, many non-student participants report having a hangover, especially when their subjective intoxication levels are high. This may be the case when alcohol consumption on the drinking occasion that results in a hangover significantly exceeds their "normal" drinking level, irrespective of whether they meet the 0.11% threshold in any of these conditions. Whereas consumers may have relative tolerance to the adverse effects at their "regular" drinking level, considerably higher alcohol intake-irrespective of the absolute amount-may consequentially result in a next-day hangover. Taken together, these findings suggest that the 0.11% threshold value as a criterion for having a hangover should be abandoned.

Alcohol Hangover Has Detrimental Impact Upon Both Executive Function and Prospective Memory.

The alcohol hangover (AH) is a state of general malaise following an evening of heavy episodic drinking when the blood alcohol concentration of the person reaches/approaches zero. The aim of the current study was to investigate what impact the AH has upon both executive function (EF) and prospective memory (PM). Previous research has shown that the AH has a detrimental effect upon cognitive abilities, including attention, working memory, and PM. The current study focused upon what impact AH might have upon both EF and related PM in the same cohort, both of which underpin everyday remembering. The current study compared an AH group (AHG) with a non-hangover group (NHG) on both EF and PM measures. Forty-one participants aged 18-29 years were tested; 19 comprised the AHG and 22 of whom made up the NHG (individuals who reported no heavy drinking the day before and did not report any significant hangover symptoms). A Verbal Fluency task measured EF and the Prospective Remembering Video Procedure measured PM. The Acute Hangover Rating Scale measured AH symptoms and severity, and a Digital Breath Analyzer Test measured their blood alcohol concentration (BAC). A Recreational Drug Use Questionnaire measured alcohol and other drug use. Anyone reporting having used an illicit substance across their lifetime (e.g., cannabis, ecstasy) or who smoked heavily were omitted from the study. Two univariate analyses of covariance compared the AHG and NHG groups on Verbal Fluency and Prospective Remembering Video Task scores (controlling for age, total alcohol units consumed per week, and the number of years spent drinking). The AHG recalled significantly fewer items on the Verbal Fluency task [F (1, 36) = 7.42, p < 0.01] and on the Prospective Remembering Video Task NHG [F (1, 36) = 14.9, p < 0.001] when compared with the NHG. Overall, it appeared that a state of AH significantly impaired both EF and PM. Given the importance of EF and PM to everyday remembering, these findings may have farther-reaching implications.

Objectively assessed prospective memory failures and diurnal cortisol secretion in caregivers of children with ASD.

Caregivers of children with autism spectrum disorder (ASD) self-report more prospective memory (PM) failures compared with controls. Subjective and objective measures of PM, however, tend to be poorly correlated. This study therefore explored the cognitive impact of caring for a child with ASD using the Cambridge Prospective Memory Test (CAMPROMPT), a more objective, performance-based assessment of PM failures. Whether atypical cortisol secretion patterns might mediate caregivers' compromised cognition was also explored. A sample of n = 23 caregivers of children with ASD and n = 11 parent controls completed time- and event-cued PM tasks with CAMPROMPT. Diurnal cortisol indices, the cortisol-awakening response, diurnal cortisol slope, and mean diurnal output were estimated from saliva samples on multiple days. Results indicated objectively assessed event- but not time-cued PM failures were greater in caregivers compared with controls. Variations in cortisol secretion patterns, however, did not mediate the group effect. In conclusion, caring for a child with ASD was associated with greater deficits in event-cued PM. Future studies might examine the influence of caregivers' event-cued PM failures on quality of provided care. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

A State of Alcohol Hangover Impedes Everyday Prospective Memory.

The aim of the current study was to investigate what impact a state of alcohol hangover (AH) has upon everyday prospective memory (PM; memory for future events/intentions). Previous research has shown that the AH has a detrimental effect upon cognitive abilities, including memory and attentional deficits. No published research articles to date have focused upon what impact AH might have upon everyday memory, of which PM is a good example. The current study compared an AH group (AHG) with a non-hangover group (NHG) on PM. Since other drug use, anxiety and depression can affect PM independent of the AH, these covariates were controlled for in the study. Fifty-eight young adults studying at university participated in this between-subjects design study-25 in the AHG and 33 in the NHG. The Prospective Remembering Video Procedure (PRVP) measured PM. The Acute Hangover Rating Scale confirmed a state of AH and a Digital Breath Analyzer Test measured their BAC. The Hospital Anxiety and Depression Scale gauged levels of anxiety and depression and a Recreational Drug Use Questionnaire (RDUQ) measured alcohol and other drug use. Anyone who reported having used an illicit substance (e.g., cannabis, ecstasy) or who smoked, were excluded from the study. After controlling for age, alcohol units per week, years spent drinking alcohol, anxiety and depression scores, a one-way analysis of covariance (ANCOVA) revealed that the AHG (mean = 5.16) recalled significantly fewer items on the PRVP than the NHG (mean = 7.51)-F (1,52) = 5.69, p < 0.05. Overall, it appeared that a state of AH significantly impaired PM, which was not attributable to age, alcohol use, or anxiety or depression indices. Given the importance of PM to everyday activities, such as remembering to keep appointments or to take an important medication on time, this finding may have farther-reaching implications. These findings should also be used to educate young adults and health professionals dealing with the consequences with regards the dangers of alcohol misuse.

Phase II study of Vigil® DNA engineered immunotherapy as maintenance in advanced stage ovarian cancer.

OBJECTIVES: The majority of women with Stage III/IV ovarian cancer who achieve clinical complete response with frontline standard of care will relapse within 2years. Vigil immunotherapy, a GMCSF/bi-shRNA furin DNA engineered autologous tumor cell (EATC) product, demonstrated safety and induction of circulating activated T-cells against autologous tumor in Phase I trial Senzer et al. (2012, 2013) . Our objectives for this study include evaluation of safety, immune response and recurrence free survival (RFS). METHODS: This is a Phase II crossover trial of Vigil (1.0×107 cells/intradermal injection/month for 4 to 12 doses) in Stage III/IV ovarian cancer patients achieving cCR (normal imaging, CA-125≤35units/ml, physical exam, and no symptoms suggestive of the presence of active disease) following primary surgical debulking and carboplatin/paclitaxel adjuvant or neoadjuvant chemotherapy. Patients received Vigil or standard of care during the maintenance period. RESULTS: Forty-two patients were entered into trial, 31 received Vigil and 11 received standard of care. No≥Grade 3 toxicity related to product was observed. A marked induction of circulating activated T-cell population was observed against individual, pre-processed autologous tumor in the Vigil arm as compared to pre-Vigil baseline using IFNγ ELISPOT response (30/31 negative ELISPOT pre Vigil to 31/31 positive ELISPOT post Vigil, median 134 spots). Moreover, in correlation with ELISPOT response, RFS from time of procurement was improved (mean 826days/median 604days in the Vigil arm from mean 481days/median 377days in the control arm, p=0.033). CONCLUSION: In conjunction with the demonstrated safety, the high rate of induction of T-cell activation and correlation with improvement in RFS justify further Phase II/III assessment of Vigil.

The Synergistic Impact of Excessive Alcohol Drinking and Cigarette Smoking upon Prospective Memory.

The independent use of excessive amounts of alcohol or persistent cigarette smoking have been found to have a deleterious impact upon Prospective Memory (PM: remembering future intentions and activities), although to date, the effect of their concurrent use upon PM is yet to be explored. The present study investigated the impact of the concurrent use of drinking excessive amounts of alcohol and smoking cigarettes (a "Polydrug" group) in comparison to the combined effect of the single use of these substances upon PM. The study adopted a single factorial independent groups design. The Cambridge Prospective Memory Test (CAMPROMPT) is a test of both time-based and event-based PM and was used here to measure PM. The CAMPROMPT was administered to 125 adults; an excessive alcohol user group (n = 40), a group of smokers who drink very little alcohol (n = 20), a combined user group (the "Polydrug" group) who drink excessively and smoke cigarettes (n = 40) and a non-drinker/low alcohol consumption control group (n = 25). The main findings revealed that the Polydrug users recalled significantly fewer time-based PM tasks than both excessive alcohol users p < 0.001 and smokers p = 0.013. Polydrug users (mean = 11.47) also remembered significantly fewer event-based PM tasks than excessive alcohol users p < 0.001 and smokers p = 0.013. With regards to the main aim of the study, the polydrug users exhibited significantly greater impaired time-based PM than the combined effect of single excessive alcohol users and cigarette smokers p = 0.033. However, no difference was observed between polydrug users and the combined effect of single excessive alcohol users and cigarette smokers in event-based PM p = 0.757. These results provide evidence that concurrent (polydrug) use of these two substances has a synergistic effect in terms of deficits upon time-based PM. The observation that combined excessive drinking and cigarette smoking leads to a greater impairment in time-based PM may be of paramount importance, given the key role PM plays in everyday independent living.

Allometric scaling of strength scores in NCAA division I-A football athletes.

This study examined population-specific allometric exponents to control for the effect of body mass (BM) on bench press, clean, and squat strength measures among Division I-A collegiate football athletes. One repetition maximum data were obtained from a university pre-season football strength assessment (bench press, n = 207; clean, n = 88; and squat n = 86) and categorized into 3 groups by positions (line, linebacker, and skill). Regression diagnostics and correlations of scaled strength data to BM were used to assess the efficacy of the allometric scaling model and contrasted with that of ratio scaling and theoretically based allometric exponents of 0.67 and 0.33. The log-linear regression models yielded the following exponents (b): b = 0.559, 0.287, and 0.496 for bench press, clean, and squat, respectively. Correlations between bench press, clean, and squat to BM were r = -0.024, -0.047, and -0.018, respectively, suggesting that the derived allometric exponents were effective in partialling out the effect of BM on these lifts and removing between-group differences. Conversely, unscaled, ratio-scaled, and allometrically scaled (b = 0.67 or 0.33) data resulted in significant differences between groups. It is suggested that the exponents derived in the present study be used for allometrically scaling strength measures in National Collegiate Athletic Association Division I-A football athletes. Use of the normative percentile rank scores provide coaches and trainers with a valid means of judging the effectiveness of their training programs by allowing comparisons between individuals without the confounding influence of BM.

Exposure to second-hand smoke damages everyday prospective memory.

AIMS: Prospective memory (PM: remembering future intentions and activities) is critical to everyday remembering. This study compared a group of never-smokers who reported regular exposure to second-hand smoke (the SHS group) with a group of current smokers (the CS group) and a group of never-smokers who reported never having been exposed to SHS (the non-SHS group) on objective PM. DESIGN: An existing groups design was employed to compare the SHS, CS and non-SHS groups. PARTICIPANTS AND SETTING: Twenty-four SHS, 27 CS and 28 non-SHS were tested on objective PM. All participants were university undergraduates aged between 18-30 years. All participants were tested individually in a laboratory setting. MEASUREMENTS: The Cambridge Prospective Memory Test (CAMPROMPT) was used to assess objective PM. Age, other drug use, mood and IQ were also measured as covariates in the study. FINDINGS: The non-SHS group recalled significantly more time-based PM tasks than the SHS group (means = 16.3 versus 13.7, P < 0.001) and significantly more than the CS group (CS mean = 11.6, P < 0.001); and the SHS group recalled significantly more time-based tasks than the CS group (P < 0.002). The non-SHS group recalled significantly more event-based PM tasks than the CS group (means = 15.2 versus 11.3, P < 0.002) with no significant difference between the non-SHS group and SHS group (SHS mean = 14.3, P = 0.234); and the SHS group recalled significantly more event-based tasks than the CS group (P < 0.001). CONCLUSION: Non-smokers exposed to second-hand smoke may suffer impairment in time-based prospective memory.

Everyday prospective memory and executive function deficits associated with exposure to second-hand smoke.

This study explored whether exposure to second-hand smoke (SHS) has a detrimental impact upon everyday memory in two groups of non-smokers; one which reported regular exposure to SHS and one that reported never having been exposed to SHS. Thirty-four non-smokers who reported having been regularly exposed to SHS (SHS group) and 34 non-smokers who reported never having been exposed to SHS (non-SHS group) were compared on self-reports of prospective memory (PM: remembering future intentions and/or activities) and executive function (EF: those processes involved in attention, multitasking and decision-making). The Prospective and Retrospective Memory Questionnaire (PRMQ) assessed everyday PM lapses; the Executive Function Questionnaire (EFQ) assessed self-reported problems in EF; a drug-use questionnaire and a mood questionnaire were also administered. Two univariate ANCOVAs were applied to the PM and EF data, controlling for between-group differences in age, weekly alcohol use, anxiety and depression scores, and self-reported retrospective memory scores. The SHS group reported significantly more lapses on the PRMQ and more deficits on the EFQ than the non-SHS group. These findings provide new insights into PM and EF deficits associated with prolonged exposure to SHS in a group of non-smokers. Possible explanations and suggestions for future research are also considered.

Time based prospective memory deficits associated with binge drinking: evidence from the Cambridge Prospective Memory Test (CAMPROMPT).

AIMS: To examine whether 'binge drinking' (BD) in young adults adversely affects prospective memory (PM). BD was defined as males drinking 8/more units and females 6/more units on at least one session per-week. BDs and non-binge drinkers (NBDs) were compared on self-reported and objective PM. DESIGN: An existing-groups design compared BDs with NBDs as the independent factor. Scores on the PM and retrospective memory (RM) subscales of the Prospective and Retrospective Memory Questionnaire (PRMQ) and scores on the Cambridge Prospective Memory Task (CAMPROMPT) were the dependent factors. Age, total years spent drinking, time since last drink consumed (hours), mood, strategy-use and pre-morbid IQ were measured as covariates. SETTING: Each participant was tested in a laboratory setting. PARTICIPANTS: An opportunity sample of 28 BDs and 28 NBDs were compared. MEASUREMENTS: Self-reported PM and RM lapses were measured using the PRMQ and the CAMPROMPT measured objective PM. Drug use was assessed using a Recreational Drug Use Questionnaire. The Hospital Anxiety and Depression Scale measured mood. The strategy-scale from the Prospective Memory Questionnaire measured strategy use. The National Adult Reading Test measured pre-morbid IQ. FINDINGS: BDs and NBDs did not differ in terms of gender makeup and a series of ANCOVAs (controlling for the covariates) revealed no significant between-groups differences on self-reported PM/RM lapses; but BDs exhibited reduced function on time-based PM, but not event-based PM, when compared with NBDs. CONCLUSIONS: BDs exhibit selective impairments on time-based PM; this deficit is a new finding in terms of the neuropsychological sequelae associated with BD.

A short self-report measure of problems with executive function suitable for administration via the Internet.

This article describes a short self-report measure of problems with executive function designed for use in Internet-mediated research. In Study 1, participants completed the online measure (Webexec) using a browser but under laboratory conditions. They also completed a paper self-report measure of executive problems (the Dysexecutive Questionnaire; DEX) and three objective tasks involving executive function: reverse digit span, semantic fluency (unconstrained), and semantic fluency (constrained). Webexec scores correlated positively with the DEX and negatively with the three executive tasks. Further evidence of construct validity came from Study 2, in which Webexec scores correlated positively with both use of cannabis and prospective memory problems reported in an online drug questionnaire. Webexec thus appears suitable for online research with normal populations.

Smoking and everyday prospective memory: a comparison of self-report and objective methodologies.

AIMS: To examine whether persistent smoking leads to impairments in self-reported and objective measures of prospective memory (PM: the cognitive ability to remember to carry out activities at some future point in time). METHODS: An opportunity sample of 18 existing smokers and 22 who had never smoked were compared. An existing-groups design was utilised, comparing a smoking group with a never-smoked control group as the independent factor. Scores on the sub-scales of the Prospective and Retrospective Memory Questionnaire (PRMQ) and scores on the Cambridge Prospective Memory Test (CAMPROMPT) constituted the dependent factors. Age, mood, other drug use, strategy scores and IQ were also measured. Each participant was tested in a laboratory setting. Self-reported PM lapses were measured using the PRMQ. The CAMPROMPT was used as an objective measure of PM. Alcohol and other drug use were assessed by a Recreational Drug Use Questionnaire. The Hospital Anxiety and Depression Scale gauged levels of anxiety and depression. A strategy scale measured the number of strategies used to aid memory. The National Adult Reading Test measured IQ. RESULTS: After observing no between-group differences on age, mood, alcohol use, strategy use, and IQ, smokers and the never-smoked did not differ on the self-reported lapses measured on the PRMQ. However, smokers recalled significantly fewer items on the CAMPROMPT than the never-smoked group. CONCLUSION: The results of the present study suggest that persistent smoking leads to impairments in everyday PM.

Subjective ratings of prospective memory deficits in chronic alcohol users.

Previous research showing everyday memory is impaired by heavy alcohol use may have underestimated the cognitive impairment of heavy users because drinkers consuming over the recommended limits for safe drinking have often been treated as a homogeneous group, often with a low threshold for inclusion. The current study investigated whether the reported linear relationship applies to participants consuming alcohol significantly above recommended limits. The everyday memory of 80 participants (43 men; modal age, 31-35 years) was investigated using the Prospective Memory Questionnaire. Participants also detailed their average weekly intake of alcohol and other substances. Current heavy users of alcohol (who consumed on average over 25 units per week) reported more memory problems than low (1-9 units per week) or medium users (10-25 units per week). Participants undergoing counselling for alcohol use reported more deficits than low or medium drinkers, but fewer than current heavy drinkers. Possible reasons for this were discussed. Strengths and limitations of subjective approaches to memory assessment were discussed as well as suggestions for future research.

Cognitive and psychomotor performance during alcohol hangover.

The consequences of alcohol consumption have risen high on health and social agendas in recent years. Although much work has focused on the physical problems associated with alcohol use, one theme that has emerged in alcohol research has been a focus on the effects of hangovers on functioning. This brief literature review specifically examines recent empirical investigations of the relationship between alcohol hangover and psychological performance and is tabled as an update to our earlier review of similar research (Stephens et al., 2008). A literature search generated 75 results on hangover and cognition (and synonyms) since the last published review. However, of these, only 4 met all inclusion criteria, such as establishing that BAL (Blood Alcohol Level) was zero at testing. Taking the findings of these newer studies with those that we reviewed previously, there appears to be real evidence of convergence of findings. There are now four rigorous laboratory studies, two less rigorous laboratory studies lacking placebo control and two rigorous naturalistic studies that indicate specific cognitive decrements in attention and memory during the hangover phase of alcohol consumption. Given this convergence, research agendas for increasing understanding of the cognitive effects of alcohol hangover should now switch from studies that routinely assess many cognitive functions to studies assessing the attention and memory deficits of hangover in greater detail.

The alcohol hangover research group consensus statement on best practice in alcohol hangover research.

Alcohol-induced hangover, defined by a series of symptoms, is the most commonly reported consequence of excessive alcohol consumption. Alcohol hangovers contribute to workplace absenteeism, impaired job performance, reduced productivity, poor academic achievement, and may compromise potentially dangerous daily activities such as driving a car or operating heavy machinery. These socioeconomic consequences and health risks of alcohol hangover are much higher when compared to various common diseases and other health risk factors. Nevertheless, unlike alcohol intoxication the hangover has received very little scientific attention and studies have often yielded inconclusive results. Systematic research is important to increase our knowledge on alcohol hangover and its consequences. This consensus paper of the Alcohol Hangover Research Group discusses methodological issues that should be taken into account when performing future alcohol hangover research. Future research should aim to (1) further determine the pathology of alcohol hangover, (2) examine the role of genetics, (3) determine the economic costs of alcohol hangover, (4) examine sex and age differences, (5) develop common research tools and methodologies to study hangover effects, (6) focus on factor that aggravate hangover severity (e.g., congeners), and (7) develop effective hangover remedies.

Recurrent phyllodes tumor of the vulva: a case report with review of diagnostic criteria and differential diagnosis.

Phyllodes tumor of the vulva is extremely rare with only 6 cases reported in the literature. We report a case of recurrent phyllodes tumor of the vulva in a 39-year-old woman. The tumor showed biphasic morphology with a typical leaf-like pattern and a cellular stroma with rare mitosis. Expression of estrogen receptors, progesterone receptors mammoglobin, and BRST-2 was shown in the epithelial component. Review of literature with emphasis on diagnostic features and differential diagnosis are discussed.

Loop electrosurgical excision procedure and risk of preterm birth.

OBJECTIVE: To examine whether preterm birth is related to the loop electrosurgical excision procedure (LEEP) itself or intrinsic to the women undergoing the procedure. METHODS: Rates of preterm birth, defined as births before 37 weeks of gestation, as well as causes were analyzed in women undergoing LEEP before or after an index pregnancy. These rates were compared with the general obstetric population. RESULTS: A total of 241,701 women were delivered of singletons at Parkland Hospital between January 1992 and May 2008; of these women, 511 previously had undergone LEEP and another 842 underwent LEEP after the index pregnancy. When compared with the general obstetric population, no increased risk of preterm birth was observed for either group. This was true regardless of the reason for preterm birth. Likewise, there was no increased risk of delivery before 34 weeks or between 34 and 36 weeks of gestation. CONCLUSION: No association was observed between LEEP and preterm birth in women undergoing the procedure before or after an index pregnancy.
