The transformative potential of reflective diaries for elite English cricketers
The sport of cricket has a history of its players suffering from mental health issues. The psychological study of cricket and, in particular, the attendant demands of participating at an elite level has not previously received rigorous academic attention. This study explored ten elite male cricketers’ experiences of keeping a daily reflective diary for one month during the competitive season. The aim was to assess how valuable qualitative diaries are in this field. Participants were interviewed regarding their appraisal of the methodology as a self‐help tool that could assist coping with performance pressures and wider life challenges. Three outcomes were revealed: first, that diary keeping was an effective opportunity to reflect upon the past and enhance one’s self (both as an individual and a performer); second, that diary keeping acted as a form of release that allowed participants to progress; and third, that diary keeping allowed participants to discover personal patterns of success that increased the likeliness of optimum performance
Does telephone testing of long-term memory retention and forgetting influence performance in young and older adults? An examination using the Crimes Test
Measuring memory over long delays requires multiple sessions, often administered remotely (e.g. by telephone) to maximise convenience and participant access. However, the efficacy of testing delayed memory via telephone has not previously been examined. We administered the Crimes Test to young and older adults, with a one-week delay test either in person or over the telephone. Testing via telephone had no detrimental effect, indicating this to be an appropriate method of examining delayed episodic memory
Estimating the Sex Composition of the Summer Flounder Catch using Fishery-Independent Data
Models that account for sex-specific behavior and population dynamics are becoming more common in the stock assessment of sexually dimorphic fishes. However, such models can be data intensive and require some knowledge or assumptions about the sex ratio of fishery landings. A recent stock assessment review of Summer Flounder Paralichthys dentatus identified the need to account for sex-specific fishing mortality in the assessment model; however, no data on the sex composition of the catch were available. Fishery-independent, sex-specific information for this species is collected annually by the National Marine Fisheries Service\u27s Northeast Fisheries Science Center during their bottom trawl survey. Sex at age from the survey could be applied to the fishery landings if the probability of landing a given sex at a given age is equivalent for fish collected by the survey and those in the landings. To generate the first regionally comprehensive database on the sex ratio of Summer Flounder landings and to determine the efficacy of using survey sex-at-age keys to estimate the sex of landed fish, we recorded the sex composition of the commercial and recreational catches of Summer Flounder (n = 31,912) in 2010 and 2011. When (1) trawl survey length data were left-truncated to simulate the minimum retention sizes in the fisheries and (2) age-length keys generated from fishery-dependent data were applied to length frequency distributions from the survey to simulate the growth rates of landed fish, the sex-at-age pattern in the survey-derived data closely resembled the patterns in the catch. However, statistically significant differences in sex at age remained between the catch and the survey-derived data. We hypothesize that these differences are attributable to differences in the spatiotemporal distributions of the sexes and of the survey and fishing effort
Effectiveness of a web-based intervention to prevent anxiety in the children of parents with anxiety:Protocol for a Randomized Controlled Trial
Effectiveness of a web-based intervention to prevent anxiety in the children of parents with anxiety:Protocol for a Randomized Controlled Trial
BACKGROUND: Anxiety is the most common childhood mental health condition and is associated with impaired child outcomes, including increased risk of mental health difficulties in adulthood. Anxiety runs in families: when a parent has anxiety, their child has a 50% higher chance of developing it themselves. Environmental factors are predominant in the intergenerational transmission of anxiety and, of these, parenting processes play a major role. Interventions that target parents to support them to limit the impact of any anxiogenic parenting behaviors are associated with reduced anxiety in their children. A brief UK-based group intervention delivered to parents within the UK National Health Service led to a 16% reduction in children meeting the criteria for an anxiety disorder. However, this intervention is not widely accessible. To widen access, a 9-module web-based version of this intervention has been developed. This course comprises psychoeducation and home practice delivered through text, video, animations, and practice tasks. OBJECTIVE: This study seeks to evaluate the feasibility of delivering this web-based intervention and assess its effectiveness in reducing child anxiety symptoms. METHODS: This is the protocol for a randomized controlled trial (RCT) of a community sample of 1754 parents with self-identified high levels of anxiety with a child aged 2-11 years. Parents in the intervention arm will receive access to the web-based course, which they undertake at a self-determined rate. The control arm receives no intervention. Follow-up data collection is at months 6 and months 9-21. Intention-to-treat analysis will be conducted on outcomes including child anxiety, child mental health symptoms, and well-being; parental anxiety and well-being; and parenting behaviors. RESULTS: Funding was received in April 2020, and recruitment started in February 2021 and is projected to end in October 2022. A total of 1350 participants have been recruited as of May 2022. CONCLUSIONS: The results of this RCT will provide evidence on the utility of a web-based course in preventing intergenerational transmission of anxiety and increase the understanding of familial anxiety.

Tortoise or hare? Supporting the chronotype preference of employees with fluctuating chronic illness symptoms
Objective: Our aim is to understand how to facilitate the job retention of employees with chronic illness. We focus on multiple sclerosis (MS) as a criterion chronic illness.
Design: An opportunity sample of 20 individuals of working age (13 female; 7 male) were recruited who had been in paid employment for over 28 months with a concurrent diagnosis of MS. Participants took part in one of three focus groups with a topic guide comprising eight keywords: work, coping, performance, support, future, expectations, and sharing symptoms. Data were analysed using dialogical analysis.
Main outcome measures: As a qualitative study, no outcome measure was used. However, the specific focus of interest was to search for differential patterns of ‘timespace’ – chronotope - that people with chronic illness utilize to manage their condition in the workplace.
Results: Participants oriented to two distinct chronotope types: unsustainable epic (characterized by condensed time) and temporary idyll (characterized by condensed space). Perceived managerial discretion was identified as possibly influencing participants’ chronotope preference.
Conclusion: Identifying chronotope preference has practical implications for health psychologists and related professionals who provide and advise on support to facilitate people with chronic illness to thrive in the workplace
Validation of the italian version of the Cluster Headache Impact Questionnaire (CHIQ)
Background: The Cluster Headache Impact Questionnaire (CHIQ) is a specific and easy-to-use questionnaire to assess the current impact of cluster headache (CH). The aim of this study was to validate the Italian version of the CHIQ. Methods: We included patients diagnosed with episodic CH (eCH) or chronic CH (cCH) according to the ICHD-3 criteria and included in the “Italian Headache Registry” (RICe). The questionnaire was administered to patients through an electronic form in two sessions: at first visit for validation, and after 7 days for test-retest reliability. For internal consistency, Cronbach’s alpha was calculated. Convergent validity of the CHIQ with CH features and the results of questionnaires assessing anxiety, depression, stress, and quality of life was evaluated using Spearman’s correlation coefficient. Results: We included 181 patients subdivided in 96 patients with active eCH, 14 with cCH, and 71 with eCH in remission. The 110 patients with either active eCH or cCH were included in the validation cohort; only 24 patients with CH were characterized by a stable attack frequency after 7 days, and were included in the test-retest cohort. Internal consistency of the CHIQ was good with a Cronbach alpha value of 0.891. The CHIQ score showed a significant positive correlation with anxiety, depression, and stress scores, while showing a significant negative correlation with quality-of-life scale scores. Conclusion: Our data show the validity of the Italian version of the CHIQ, which represents a suitable tool for evaluating the social and psychological impact of CH in clinical practice and research

Untargeted LC-HRMS-based metabolomics to identify novel biomarkers of metastatic colorectal cancer
Colorectal cancer is one of the main causes of cancer death worldwide, and novel biomarkers are
urgently needed for its early diagnosis and treatment. The utilization of metabolomics to identify
and quantify metabolites in body fluids may allow the detection of changes in their concentrations
that could serve as diagnostic markers for colorectal cancer and may also represent new therapeutic
targets. Metabolomics generates a pathophysiological ‘fingerprint’ that is unique to each individual.
The purpose of our study was to identify a differential metabolomic signature for metastatic colorectal
cancer. Serum samples from 60 healthy controls and 65 patients with metastatic colorectal cancer were
studied by liquid chromatography coupled to high-resolution mass spectrometry in an untargeted
metabolomic approach. Multivariate analysis revealed a separation between patients with metastatic
colorectal cancer and healthy controls, who significantly differed in serum concentrations of one
endocannabinoid, two glycerophospholipids, and two sphingolipids. These findings demonstrate that
metabolomics using liquid-chromatography coupled to high-resolution mass spectrometry offers a
potent diagnostic tool for metastatic colorectal cancer.This study was supported by a grant (n° 15CC056/DTS17/00081- ISCIII-FEDER) from the Fundación para la
