Multispecies probiotic administration reduces emotional salience and improves mood in subjects with moderate depression: a randomised, double-blind, placebo-controlled study.

BACKGROUND: The potential antidepressant properties of probiotics have been suggested, but their influence on the emotional processes that may underlie this effect is unclear. METHODS: Depressed volunteers (n = 71) were recruited into a randomised double-blind, placebo-controlled study to explore the effects of a daily, 4-week intake of a multispecies probiotic or placebo on emotional processing and cognition. Mood, anxiety, positive and negative affect, sleep, salivary cortisol and serum C-reactive peptide (CRP) were assessed before and after supplementation. RESULTS: Compared with placebo, probiotic intake increased accuracy at identifying faces expressing all emotions (+12%, p < 0.05, total n = 51) and vigilance to neutral faces (mean difference between groups = 12.28 ms ± 6.1, p < 0.05, total n = 51). Probiotic supplementation also reduced reward learning (-9%, p < 0.05, total n = 51), and interference word recall on the auditory verbal learning task (-18%, p < 0.05, total n = 50), but did not affect other aspects of cognitive performance. Although actigraphy revealed a significant group × night-time activity interaction, follow up analysis was not significant (p = 0.094). Supplementation did not alter salivary cortisol or circulating CRP concentrations. Probiotic intake significantly reduced (-50% from baseline, p < 0.05, n = 35) depression scores on the Patient Health Questionnaire-9, but these did not correlate with the changes in emotional processing. CONCLUSIONS: The impartiality to positive and negative emotional stimuli or reward after probiotic supplementation have not been observed with conventional antidepressant therapies. Further studies are required to elucidate the significance of these changes with regard to the mood-improving action of the current probiotic.

Beliefs about sensitive parenting among mothers of children with disabilities.

The relevance of the quality of parent-child interactions for child development has long been established. Nevertheless, research on beliefs about maternal sensitivity is still scarce, to an even greater extent in the context of child disability. This inquiry aimed to describe beliefs about sensitive parenting among mothers of children with developmental disabilities and to examine how those beliefs relate to sociodemographic factors and perceived stress. Participants included 40 mothers with a child up to 7 years of age with a developmental disability. Mothers reported on sociodemographic factors and daily hassles and sorted an adapted version of the Maternal Behavior Q-Sort. Results revealed a strong convergence between maternal beliefs about the ideal mother and the attachment theory's concept of sensitivity. Daily hassles predicted beliefs about the ideal mother. These results underline the importance of implementing interventions in the context of child disability aimed at reducing parental stress.

Fears of happiness and compassion in relationship with depression, alexithymia, and attachment security in a depressed sample.

OBJECTIVES: In a non-clinical population, fears of compassion and fear of happiness have both been found to be highly correlated with alexithymia and depression. This study sought to explore these processes and their links with adult attachment and social safeness and pleasure in a depressed group. METHOD: A total of 52 participants suffering from moderate to severe depression completed measures of fears of happiness, compassion from others and for self, in addition to measures of alexithymia, attachment, social safeness, and depression, anxiety, and stress. RESULTS: Fears of compassion and happiness were highly correlated with alexithymia, adult attachment, and depression, anxiety, and stress. Fear of happiness was found to be the best predictor of depression, anxiety, and stress, whereas fear of compassion from others was the best predictor of adult attachment. A path analysis showed that fears of positive emotion fully mediate the link between alexithymia and depression. This clinical sample had higher mean scores in fears of positive emotions, alexithymia, and depression, anxiety, and stress than a previously studied student sample. CONCLUSIONS: This study adds to the evidence that fears of positive emotions are important features of mental health difficulties. Unaddressed, these fears can block positive emotions and may lead to emotional avoidance of positive affect thus contributing as blocks to successful therapy. Therapies for depression may therefore profitably assess and desensitize the fear of positive emotions.

Risk of SARS-CoV-2 Infection and COVID-19 Severity Associated With Exposure to Nonsteroidal Anti-Inflammatory Drugs: Systematic Review and Meta-Analysis.

Nonsteroidal anti-inflammatory drugs (NSAIDs) were thought to increase the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus entrance into cells. Hence, it was suggested in the media that NSAIDs could lead to a higher risk of infection and/or disease severity. To determine the existence or absence of this association, we aimed to systematically evaluate the risk of SARS-CoV-2 infection and mortality and the risk of severe coronavirus disease 2019 (COVID-19) associated with previous exposure to NSAIDs. MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE were searched in February 2021 for controlled studies. The results were calculated through random-effect meta-analyses and reported in terms of odds ratios (ORs) with 95% confidence intervals (CIs). Heterogeneity was assessed with I2 test. Eleven studies were included, comprising a total of 683 715 patients. NSAID exposure did not increase the risk of having a positive test for SARS-CoV-2 infection (OR, 0.97; 95%CI, 0.85-1.11, I2 = 24%; 5 studies). The exposure to NSAIDs did not increase the risk of severe/critical COVID-19 disease (OR, 0.92; 95%CI, 0.80-1.05; I2 = 0%; 5 studies) nor all-cause mortality among patients with COVID-19 (OR, 0.86; 95%CI, 0.75-0.99; I2 = 14%, 4 studies). Our data did not suggest that exposure to NSAIDs increases the risk of having SARS-CoV-2 infection or increases the severity of COVID-19 disease. Also, the fragility of the studies included precludes definite conclusions and highlights the need for further robust data.

Does 5-HTTLPR moderate the effect of the quality of environmental context on maternal sensitivity? Testing the differential susceptibility hypothesis.

Evidence documenting associations between 5-HTTLPR and parenting behavior led to testing the hypothesis that this polymorphism moderates the effect of the quality of environmental context on maternal sensitivity. Participants were 210 Portuguese mothers and their preschool children, recruited from the community. An index reflecting the quality of the environmental context was derived based on nine markers (e.g. single parenthood; parental education, economic difficulties, family conflict, maternal psychopathology). Maternal sensitivity was measured observationally. Maternal saliva was collected with OraGene kits for genetic analysis. Results revealed a gene-X-environment interaction, such that short-allele homozygotes proved more sensitive to the family context than long-allele carriers (i.e. sL/LL), displaying the highest and lowest levels of maternal sensitivity, depending on, respectively, low and high quality levels of the environmental context. Because even mothers carrying the long allele evinced similar responsiveness to the environmental context, but to a lesser extent, findings proved consistent with the weak differential susceptibility model of person-X-context interaction. Results are discussed in light of prior and related gene-X-environment findings.

Prebiotic supplementation does not affect reading and cognitive performance in children: A randomised placebo-controlled study.

Based on the emerging interest in the effects of gut microbiota on cognition, this proof-of-concept study assessed how children aged 7 to 9 with low reading scores responded to the ingestion of a 3-month prebiotic supplement versus a placebo. As a secondary aim, the effects of the prebiotic on cognition, sleep, behaviour, mood, anxiety, and cortisol were assessed. In this sample, the prebiotic did not affect any of the outcome measures.

Child's oxytocin response to mother-child interaction: The contribution of child genetics and maternal behavior.

The oxytocinergic system is a primary biological system involved in regulating a child's needs for bonding and for protection from threats. It is responsive to social experiences in close relationships, though evidence across studies is not entirely consistent. Guided by previous literature, we investigated individual and environmental factors predicting and presumably affecting children's oxytocin (OT) response during mother-child interaction. by focusing on children's OXTR genotype, and maternal behavior, respectively. This was achieved by assessing salivary OT levels of 88 Portuguese preschoolers prior to and following a mother-child interaction task, and by genotyping children's OXTR SNP rs53576. Maternal interactive behavior was assessed using Ainsworth scales. Results indicated that child genotype and mother's sensitive responsiveness interacted in predicting change in child OT concentrations from before to after the interaction. Specifically, Genotypic differences emerged under conditions of low maternal sensitive responsiveness: OT levels increased over time for children with the GG genotype when maternal sensitive responsiveness was low, but no such genotypic differences were evident when mothers were highly sensitive responsive. Findings provide preliminary support for the notion that increased understanding of children's OT and close relationships requires consideration of both individual and environmental factors.

Forms of Self-Criticising/Attacking & Self-Reassuring Scale: Psychometric properties and normative study.

BACKGROUND: The Forms of Self-Criticising/Attacking & Self-Reassuring Scale (FSCRS, Gilbert, Clarke, Hempel, Miles, & Irons, 2004, Br. J. Clin. Psychology, 43, 31) is a self-report instrument that measures self-criticism and self-reassurance. It has shown good reliability and has been used in several different studies and in a range of different populations. The aim of this study was to explore its psychometric proprieties in a large clinical and non-clinical sample, to establish its reliability. In addition, to our knowledge, this is the first study to provide normative data to FSCRS. Differences in population scores will also be addressed. METHOD: Data were collated from 12 different studies, resulting in 887 non-clinical participants and 167 mixed diagnosis patients who completed the FSCRS. RESULTS: A confirmatory factor analysis shows that both in non-clinical and clinical samples, the three-factor model of FSCRS is a well-adjusted measure for assessing the two forms of self-criticism and a form of self-reassurance. Normative data for the scale are presented. Comparing the two populations, the non-clinical was more self-reassuring and less self-critical than the clinical one. Comparing genders, in the non-clinical population men were more self-reassuring and less self-critical than women. No significant gender differences were found in the clinical population. CONCLUSIONS: Taken together, results corroborate previous findings about the link between self-criticism and clinical population, which stresses the need to both assess and address it in therapy. Results also confirm that FSCRS is a robust and reliable instrument, which now can aid clinicians and researchers to have a better understanding of the results, taking into account the norms presented. PRACTITIONER POINTS: Practical implications The normative study of the FSCRS facilitates a better understanding of clinical and research results; The paper accounts for large clinical and non-clinical populations, which contribute to robust findings; Cautions Cultural and age differences should be carefully addressed; Generalizations to different psychopathologies deserve attention, as the clinical population considered here derived mainly from depressed participants.
