RESUMEN

The paper reports on the prevalence and performance of the Jersey cattle breed in Africa, highlighting its geographic distribution and describing the reported performance and other related characteristics from the early 1900s to the present day. The review examines the contribution of Jersey cattle in increasing the volume and efficiency of milk production across the continent. Data relating to the Jersey cattle breed has been reported in more than 30 African countries based on available material published between 1964 and 2020. A key encompassing parameter of any reference was a well-described consideration of the Jersey cattle breed (as pure or crossbred with other exotic and/or indigenous breeds) with reported performance within a variety of production systems and agro-ecologies in Africa. The main focus was on breed and performance parameters, breed types, percentage of different breed types in specific environments, reproduction method and fertility; survival and longevity; disease incidence; and production efficiency metrics such as: feed efficiency (milk unit per dry matter intake, DMI) and milk yield (MY) per unit of body weight (BW). The main performance descriptors identified were based on observations on resilience under both abiotic (heat, nutrition) and biotic (incidences of pests and diseases) stressors, milk production, BW, nutrition and utilisation of feed resources. From the literature consulted, we grouped key dairy cattle performance characteristics reported in each country under the following areas to aid comparisons; a. Milk production (Milk nutrient value, daily MY, lifetime MY and annual MY); b. Fertility traits and AFC; c. Survival and longevity, d. Production efficiency (Feed efficiency, milk per unit BW and milk per unit DMI and e. Disease incidences. Results of the review showed that the smaller stature and lower maintenance nutrient requirements of the Jersey breed means that it is better suited to tolerate the tropical production conditions in the African small-scale dairy farming sector. Detailed analyses on MY and survival showed that Jersey crosses with exotic and African indigenous breeds performed better than purebred cattle with strong evidence to support the suitability of the Jersey breed in crossbreeding with indigenous breeds for use in smallholder production systems.

RESUMEN

BACKGROUND: Stigma against lesbian, gay, bisexual or queer (LGBQ) people may increase their risk of mental illness and reduce their access to and/or benefit from evidence-based psychological treatments. Little is known about the feasibility, acceptability and effectiveness of adapted psychological interventions for sexual minority individuals in the UK. AIMS: To describe and evaluate a novel LGBQ Wellbeing group therapy for sexual minority adults experiencing common mental health problems, provided in a UK Improving Access to Psychological Therapies (IAPT) service. METHOD: An eight-session LGBQ Wellbeing group intervention was developed drawing on CBT and LGBQ affirmative principles. We compare the socio-demographic and clinical characteristics of patients who completed and dropped out of the groups, and explore changes in self-reported symptoms of depression, anxiety and functional impairment. RESULTS: Over eight courses provided, 78 service-users attended at least one session, of whom 78.2% completed the intervention (drop-out rate 21.8%). Older participants were more likely to drop out. There was a lower proportion of female and bisexual or ethnic/racial minority individuals than would be expected. There were significant reductions in severity of depression, anxiety and functional impairment following the group, and more than half of those who completed the intervention needed no further treatment. CONCLUSIONS: There was preliminary evidence of the feasibility of, and potential clinical benefit in, a group therapy intervention for sexual minority adults experiencing common mental health problems. Future research should investigate access and outcomes for participants with additional social disadvantage, e.g. those who are female, older, bisexual or ethnic/racial minority.

RESUMEN

For two centuries, Jersey cattle were exported globally, adapting to varying climates and production systems, yet the founding population remained genetically isolated on the Island of Jersey. The Island of Jersey formally allowed the importation of pure Jersey cattle in 2008. This study characterized the genetic variation of 49 popular bulls from the Island of Jersey born from 1964 to 2004 and compared them to 47 non-Island Jersey bulls and cows, primarily from the United States In addition, 21 Guernsey cattle derived from the Island of Guernsey and 71 Holstein cattle served as reference populations for genetic comparison. Cattle were genotyped on the Illumina BovineHD Beadchip producing 777,962 SNPs spanning the genome. Principal component analysis revealed population stratification within breed reflective of individual animal's continental origin. When compared to Holstein and Guernsey, all Jersey clustered together by breed. The Jersey breed demonstrated increased inbreeding in comparison to Holstein or Guernsey with slightly higher estimates of inbreeding coefficients and identity-by-descent. The Island and United States Jersey have relatively similar, yet statistically different inbreeding estimates despite vastly different population sizes and gene flow. Signatures of selection within Island Jersey were identified using genome-wide homozygosity association and marker-based FST that provided population informative single-nucleotide polymorphism (SNPs). Biological significance of the homozygosity association results identified multiple genes on chromosomes 5, 24, and 27, involved in immune function and cellular processes. Overall, genomic variation was identified between the Island and non-Island Jersey cattle producing population informative SNPs and differing runs of homozygosity (ROH) over immune regulation and metabolic genes. Results on inbreeding measures and ROH may reflect varying effective population size or differential selection with grazing systems promoting natural selection for traits such as parasite resistance, whereas confinement systems demonstrate a more intensive artificial selection. More broadly, differences in breed formation, particularly between the two Channel Island breeds, likely contributed to the variation in ROH and inbreeding. This research provides a reference for the Jersey breed based on the genetic foundation of the Island cattle as compared to the intensively selected United States cattle, and identifies regions of the genome for future investigation of immune regulation and metabolic processes.

RESUMEN

People with anorexia nervosa (AN) report socioemotional difficulties; however, measurement has been criticised for lacking ecological validity and the state or trait nature of difficulties remains unclear. Participants (n = 122) were recruited across 3 groups: people who are currently ill with AN (n = 40); people who recovered (RecAN, n = 18); healthy-control participants (n = 64). Participants completed clinical questionnaires and the Social Attribution Task. The Social Attribution Task involves describing an animation of moving shapes, scored for number of propositions offered, accuracy, and social relevance. Groups were compared cross-sectionally. Those with current AN were assessed prepsychological and postpsychological treatments. People with AN provided fewer propositions than other groups and fewer salient social attributions than healthy-control participants. Those who recovered scored intermediately and not significantly different from either group. Following treatment, people with AN demonstrated (nonsignificant) improvements, and no significance between group differences were observed. Findings suggest difficulties for people with AN in providing spontaneous social narrative and in identifying social salience.

RESUMEN

BACKGROUND: Lesbian, gay and bisexual individuals experience more anxiety and depression than heterosexual people. Little is known about their comparative treatment response to psychological interventions. AIMS: To compare sociodemographic/clinical characteristics and treatment outcomes across sexual orientation groups, for adults receiving primary care psychological interventions from Improving Access to Psychological Therapies (IAPT) services in London, adjusting for possible confounders. METHOD: Data from 188 lesbian women, 222 bisexual women, 6637 heterosexual women, 645 gay men, 75 bisexual men and 3024 heterosexual men were analysed from pre-treatment and last treatment sessions. Males and females were analysed separately. RESULTS: Before treatment, lesbian and bisexual women were more likely to report clinical levels of impairment (Work and Social Adjustment Scale) than heterosexual women; there were no significant differences in depression (PHQ-9) or anxiety (GAD-7). Bisexual men were more likely to meet depression caseness than gay men but less likely to meet anxiety caseness than gay or heterosexual men. Compared with heterosexual women, lesbian and bisexual individuals showed smaller reductions in depression and impairment, controlling for age, ethnicity, employment, baseline symptoms, number of sessions and intervention type. Bisexual women experienced significantly smaller reductions in anxiety than heterosexual women and were less likely to show recovery or reliable recovery. There were no significant differences in treatment outcomes between gay, bisexual and heterosexual men. CONCLUSIONS: Reasons for poorer outcomes in lesbian and bisexual women require investigation, for example lifetime trauma or stigma/discrimination regarding gender or sexual orientation in everyday life or within therapy services.

RESUMEN

BACKGROUND: Paruresis, or "shy bladder syndrome", is a relatively common anxiety disorder, yet little is known about the causes of, and effective treatments for this disabling condition. AIM: This report describes a case study in which a man (Peter) presenting with paruresis was treated using formulation-driven CBT, which aimed to address the idiosyncratic processes that were maintaining his anxiety and avoidance of urinating in public. METHOD: Peter attended 12 sessions of CBT including one follow-up session a month after treatment had ended. Treatment involved collaboratively developing an idiosyncratic case conceptualization (identifying longitudinal and cross-sectional factors involved in the development and maintenance of his difficulties), followed by a number of standard cognitive and behavioural interventions commonly used in evidence-based CBT protocols for other anxiety disorders. Peter completed sessional outcome measures of paruresis symptomatology, anxiety, depression, social anxiety and functional impairment. RESULTS: Peter subjectively found the intervention helpful and his scores on all of the outcome measures reduced over the course of his therapy, and were maintained at one month follow-up. CONCLUSIONS: This report adds to the scarce literature regarding effective treatments for individuals suffering with paruresis. Limitations of the design are acknowledged and ideas for further research in this area are discussed.

RESUMEN

Experimental research, supported by systematic reviews, establishes that people with eating disorders have emotional difficulties in terms of recognising, regulating and expressing their emotions. These emotional difficulties contribute to poor social functioning and problems with relationships. The existing literature includes a broad range of studies, many of which have utilised self-report measures, but experimental studies of emotions in eating disorders are still limited. The primary aim of this paper is to highlight gaps in the clinical research on emotions in eating disorders, focusing on experimental investigations from our lab and highlighting potentially useful future directions for further basic research and its translation into new developments in treatment and prevention. Recent findings using experimental paradigms to study the expression of emotions along with neuroimaging research exploring differences in facial emotion processing are discussed, and clinical implications are presented.

RESUMEN

OBJECTIVE AND METHODS: The Work and Social Adjustment Scale (WSAS) assesses patients' perceptions of impairment in everyday functioning and has been reported as a simple and reliable self-report measure in different psychiatric disorders. This study compared WSAS data from an anorexia nervosa (AN) patient group with that from healthy controls (HCs) and published data from other patient groups. A total of 160 female participants (AN, 77; HC, 83) completed the WSAS as well as measures of eating disorder symptom severity and brief assessments of anxiety and depression. RESULTS: Work and Social Adjustment Scale scores for the AN group were found to be in the severely impaired range, whereas the scores for those within the HC group indicated very little, or no impairment. Total WSAS scores in the AN group were significantly correlated with severity of clinical symptoms, and eating disorder-specific symptoms were the best predictor of social and occupational functional impairment. The greatest impairment in the AN group was reported in the realm of social leisure. CONCLUSIONS: Consistent with reports in other clinical populations, it is suggested that the WSAS could be an extremely useful and meaningful measure to assess social and occupational functioning in people with eating disorders, in addition to eating disorder-specific assessments.

RESUMEN

Problematic emotional processing has been implicated in the genesis and maintenance of anorexia nervosa (AN). This study built on existing research and explored performance-based emotional intelligence (EI) in people with AN. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) was administered to 32 women diagnosed with AN and 32 female healthy controls (HC). Compared to HC women, the AN group demonstrated significantly lower total EI scores and poorer ability to understand how emotions can progress and change over time. Despite scores within the broadly average range compared to published EI norms, there was a general pattern of poorer performance in the AN sample. Self-reported anxiety symptoms were the strongest predictor of EI, over and above a diagnosis of AN. This study adds to the literature documenting the socioemotional phenotype of AN, suggesting this group of individuals may find it relatively difficult to carry out accurate reasoning about emotions, and to use emotions and emotional knowledge to enhance thought. Anxiety was highlighted as a putative variable partially explaining why people with AN demonstrated lower EI compared to controls. Implications for further research are discussed, including the need to explore the specificity of EI difficulties in AN using larger samples and additional control groups.

RESUMEN

OBJECTIVE: Evidence suggests that poor emotional processing perpetuates anorexia nervosa (AN); however, emotional processing following recovery and interactions between aspects of processing remain unknown. This study examined beliefs about emotions, emotional tolerance and avoidance and emotion suppression to preserve relationships in recovered AN patients. It also explored whether beliefs about emotion are related to emotional avoidance. DESIGN: A cross-sectional between-groups design was employed. METHOD: Currently ill (n = 40), recovered AN patients (n = 24) and a sample of healthy controls (n = 48) completed measures of clinical and demographic background in addition to the Beliefs About Emotions, Distress Tolerance and Silencing the Self emotional processing questionnaires. RESULTS: Recovered and healthy control groups were comparable (except for higher externalised self-perception in recovered participants) and both had better emotional processing than current AN patients. Beliefs about emotions correlated with level of emotional avoidance. CONCLUSIONS: This study demonstrates functional levels of emotional processing following recovery from AN. It substantiates models proposing that maladaptive beliefs about emotions link to emotional avoidance and supports inclusion of these factors as treatment foci.

RESUMEN

OBJECTIVES. Difficulties in processing emotional states are implicated in the aetiology and maintenance of diverse health conditions, including anorexia nervosa (AN) and chronic fatigue syndrome (CFS). This study sought to explore distress tolerance, self-silencing, and beliefs regarding the experience and expression of emotions in individuals diagnosed with AN and CFS. These conditions were chosen for this study because their clinical presentation is characterized by physical symptoms, yet cognitive behavioural models suggest that emotional processing difficulties contribute to the aetiology and maintenance of both. DESIGN. A between-subjects cross-sectional design was employed. METHODS. Forty people with AN, 45 with CFS, and 48 healthy controls (HCs) completed the Distress Tolerance Scale (DTS), Silencing the Self Scale (STSS), Beliefs about Emotions Scale (BES), and measures of clinical symptomatology. RESULTS. Initial group comparisons found that both AN and CFS participants scored higher than HCs on a subscale measuring difficulties in distress tolerance. AN and CFS participants were also more likely to judge themselves by external standards, endorse statements reflecting a tendency to put the needs of others before themselves, and present an outwardly socially compliant image of themselves whilst feeling hostile within. Relative to HCs, AN participants reported more maladaptive beliefs regarding the experience of having negative thoughts and feelings and revealing these emotions to others, with CFS participants showing a non-significant trend in the same direction. After controlling for differences in age, anxiety, and depression the only significant difference to remain was that observed for the STSS care as self-sacrifice subscale. More maladaptive beliefs about the experience and expression of emotions were associated with greater degree of eating disorder symptomatology in the AN group. CONCLUSIONS. Differences in emotional processing are present in AN and CFS compared to HCs, with some disorder-specific variation, and may be associated with greater clinical symptomatology. These findings support current explanatory models of both AN and CFS, and suggest that emotional processing should be addressed in the assessment and treatment of individuals with these illnesses.

RESUMEN

OBJECTIVES: Similarities have been noted between cognitive profiles of anorexia nervosa (AN) and autism spectrum disorders (ASD). However, there are no direct comparison studies. This study aimed to compare the cognitive profile of AN against published ASD data on tasks measuring empathy, executive function and central coherence. METHODS: Currently ill AN outpatients (n = 40) were statistically compared against published ASD scores on Reading the Mind in the Eyes, Voice and Films tasks (assessing empathy), Wisconsin Card Sorting Task (WCST) (assessing executive function) and Embedded Figures Task (EFT) (assessing detail focus aspect of central coherence). RESULTS: Cognitive profiles of the groups were statistically similar, except for differences in the relative patterns of empathy scores. CONCLUSIONS: The cognitive profile in current AN resembles that of ASD with important clinical implications. Replication studies with planned comparisons, examination of the state-or trait-nature of AN profile and clarification of factors underpinning similarities are required in order to broaden understanding of both disorders.

RESUMEN

OBJECTIVES: To examine whether an impaired ability to infer emotion in people with autism spectrum disorder (ASD) and difficulty with emotional theory of mind (eToM) are limited to the ill state or if this condition is a stable deficit that persists with recovery in adults with anorexia nervosa (AN). This is in keeping with observations of similarities between the disorders. METHODS: Twenty-four participants fully recovered from AN were compared against a sample of currently ill AN patients (n = 40) and healthy controls (HCs) (n = 47) on forced-choice tasks assessing emotion recognition, basic or advanced eToM in other people, using sensory stimuli and on a written task measuring eToM ability for the self as well as for others. RESULTS: Recovered participants performed well on eToM tasks and were significantly better than currently ill patients at inferring emotions in the self and in others. However, participants recovered from AN had some slight impairment in emotion recognition relative to HCs, particularly when recognizing positive emotions. CONCLUSIONS: These findings indicate almost complete normalization of emotion recognition ability as well as the restoration of eToM in recovered patients, despite the observation of difficulties in both domains in currently ill patients. Findings suggest that similarities between AN and ASD in poor eToM are restricted to the currently ill AN state and such difficulties in AN may be a factor of starvation.

RESUMEN

OBJECTIVES: This pilot study examined whether patients with anorexia nervosa (AN) would display an empathizing-systemizing psychometric profile similar to that found in autism spectrum disorders (ASD), and whether people with AN would score highly on a measure of autistic traits. METHOD: Self-report measures of empathy, systemizing, and autistic traits were administered to 22 female AN patients and 45 female healthy controls (HC). RESULTS: AN patients and HCs did not differ significantly in their self-reported empathy and systemizing. AN patients scored significantly higher than HCs on the autism-spectrum quotient. CONCLUSIONS: Replication of these findings is required with larger samples and more sensitive measures.
