A relational investigation of Israeli gay fathers’ experiences of surrogacy, early parenthood, and mental health in the context of the COVID-19 pandemic

Perinatal distress affects approximately 10% of fathers, but little is known about how gay fathers experience the challenges surrounding childbirth and early parenting of a child. This study explored gay fathers’ experiences of having a baby via transnational surrogacy, raising that baby as a gay parent, and the context of the COVID-19 pandemic. In-depth qualitative interviews were conducted with 15 Israeli men to understand their experiences of surrogacy and early parenthood, focusing on the impact on their mental health and the relational factors involved. Secondary narrative analysis revealed that fathers constructed surrogacy as a perilous quest that required strong intentionality to undertake. The first year of parenthood was conceptualised alternately as a joyful experience and/or one that challenged fathers’ identities and mental health. A relational framework was applied to better conceptualise the fathers’ narratives, revealing that actual connections—and the potentials for links—considerably shaped experiences of surrogacy, perinatal distress and recovery. Implications for research and policy are discussed

Preparatory Test Anxiety: Cognitive, Emotionality, and Behavior Components

Test anxiety interferes with the ability to communicate knowledge during tests. Preparatory test anxiety may lead to excessive learning that reduces concentration and leads to mistakes and ineffective learning. This preliminary study developed the Preparatory Test Anxiety Questionnaire (PTAQ), tested its reliability and construct validity, and assessed whether students with preparatory test anxiety exhibit excessive learning. Additionally, it explored the relations between the subscales and the total scores of the PTAQ and the TAI. Sample included 364 undergraduate college psychology students. Results indicated that the PTAQ is comprised of the ‘cognition-emotion’ and ‘behavior’ subscales and has an adequate internal consistency and construct validity. The subscales and total score of the PTAQ were positively correlated with those of the TAI. Regression analysis showed that the Emotion-Cognition scale of the PTAQ significantly added to the explained variance, while the Behavior scale did not. Results are discussed with regard to preparatory test anxiety

PiSite: a database of protein interaction sites using multiple binding states in the PDB

The vast accumulation of protein structural data has now facilitated the observation of many different complexes in the PDB for the same protein. Therefore, a single protein complex is not sufficient to identify their interaction sites, especially for proteins with multiple binding states or different partners, such as hub proteins. PiSite is a database that provides protein–protein interaction sites at the residue level with consideration of multiple complexes at the same time, by mapping the binding sites of all complexes containing the same protein in the PDB. PiSite provides easy web interfaces with an interactive viewer working with typical web browsers, and the different binding modes can be checked visually. All of the information can also be downloaded for further analyses. In addition, PiSite provides a list of proteins with multiple binding partners and multiple binding states, as well as up-to-date statistics of protein–protein interfaces. PiSite is available at http://pisite.hgc.j

Parents' perceptions of their children's outdoor activities before and during COVID-19 crisis

This study is focused on Israeli parents' perceptions regarding the possible benefits and barriers to their children's outdoor activities as well as on their reports on the actual engagement of their children in these kinds of activities, before and during the COVID-19 crisis. We employed a mixed-method design, including a questionnaire and a semi-structured interview. The participants were 213 Israeli parents. Findings reveal that parents think that outdoor activities benefit children's physical-motor and social development and their health. They consider their long work hours and weather conditions as the main barriers to spending more time outdoors. Parents also reported going out significantly less with their children to playgrounds after the peak of the COVID-19 crisis, compared to their habits before the pandemic. The decrease in the time spent outdoors was attributed by the parents to their long work hours and to an increase in the time spent by their children in front of screens. In light of the findings, we suggest that parents need guidance in order to restore the habit of going out to close playgrounds on an almost daily basis and in order to appreciate the contribution of outdoor activities to children's connectedness and knowledge about nature

Associations of Type 2 Diabetes with Common Variants in PPARD and the Modifying Effect of Vitamin D among Middle-Aged and Elderly Chinese

BACKGROUND: Previous studies have identified that variants in peroxisome proliferator-activated receptor PPAR-δ (PPARD), a target gene of vitamin D, were significantly associated with fasting glucose and insulin sensitivity in European populations. This current study sought to determine (1) whether the genetic associations of PPARD variants with type 2 diabetes and its related traits could be replicated in Chinese Han population, and (2) whether the associations would be modified by the effect of vitamin D status. METHODS AND FINDINGS: We genotyped 9 tag single nucleotide polymorphisms (SNPs) that cover the gene of PPARD (rs2267664, rs6902123, rs3798343, rs2267665, rs2267668, rs2016520, rs2299869, rs1053049, and rs9658056) and tested their associations with type 2 diabetes risk and its related traits, including fasting glucose, insulin and HbA1c in 3,210 Chinese Hans. Among the 9 PPARD tag SNPs, rs6902123 was significantly associated with risk of type 2 diabetes (odds ratio 1.75 [95%CI 1.22-2.53]; P = 0.0025) and combined type 2 diabetes and impaired fasting glucose (IFG) (odds ratio 1.47 [95%CI 1.12-1.92]; P = 0.0054). The minor C allele of rs6902123 was associated with increased levels of fasting glucose (P = 0.0316) and HbA1c (P = 0.0180). In addition, we observed that vitamin D modified the effect of rs6902123 on HbA1c (P for interaction = 0.0347). CONCLUSIONS/SIGNIFICANCE: Our findings demonstrate that common variants in PPARD contribute to the risk of type 2 diabetes in Chinese Hans, and provided suggestive evidence of interaction between 25(OH)D levels and PPARD-rs6902123 on HbA1c

Noise-Driven Phenotypic Heterogeneity with Finite Correlation Time in Clonal Populations

There has been increasing awareness in the wider biological community of the role of clonal phenotypic heterogeneity in playing key roles in phenomena such as cellular bet-hedging and decision making, as in the case of the phage-λ lysis/lysogeny and B. Subtilis competence/vegetative pathways. Here, we report on the effect of stochasticity in growth rate, cellular memory/intermittency, and its relation to phenotypic heterogeneity. We first present a linear stochastic differential model with finite auto-correlation time, where a randomly fluctuating growth rate with a negative average is shown to result in exponential growth for sufficiently large fluctuations in growth rate. We then present a non-linear stochastic self-regulation model where the loss of coherent self-regulation and an increase in noise can induce a shift from bounded to unbounded growth. An important consequence of these models is that while the average change in phenotype may not differ for various parameter sets, the variance of the resulting distributions may considerably change. This demonstrates the necessity of understanding the influence of variance and heterogeneity within seemingly identical clonal populations, while providing a mechanism for varying functional consequences of such heterogeneity. Our results highlight the importance of a paradigm shift from a deterministic to a probabilistic view of clonality in understanding selection as an optimization problem on noise-driven processes, resulting in a wide range of biological implications, from robustness to environmental stress to the development of drug resistance

Dwelling in Strangeness: accounts of the Kingsley Hall Community, London (1965-1970)

This article explores archival accounts of the experimental community, Kingsley Hall (1965-70), established by R. D. Laing, the radical Scottish psychiatrist. The paper contributes to renewed interest in Kingsley Hall, R. D. Laing's radical psychiatry and UK counterculture. Archival sources enable not only the further exploration of already known figures but also let us hear previously unheard voices. Following a discussion of archival materials, the Hall is analyzed thematically and historically as (i) an inner spaceship; (ii) an embattled middle-class countercultural plantation; (iii) a site of spiritual renewal and development; (iv) a single-building arts colony; and (v) a countercultural experiment. Finally, it is argued that with re-evaluation of 1960s and 1970s counterculture now underway on the Left, the Hall’s experiment in Laingian countercultural psychiatry—as we may fittingly call it—may yet inform future radical projects (in mental health and beyond)

Clinical characteristics of a large familial cohort with Medullary thyroid cancer and germline Cys618Arg RET mutation in an Israeli multicenter study

ObjectiveTo determine genealogical, clinical and pathological characteristics of a cohort with Cys618Arg mutation from an Israeli multicenter MTC study.MethodsRetrospective database analysis examining RET mutations and comparing Cys618Arg and Cys634Arg/Thr/Tyr subgroups.ResultsGenetic testing was performed in 131/275 MTC patients (47.6%). RET mutations were found in 50/131 (38.2%), including Cys618Arg (28/50 cases,56%), and Cys634Arg/Thr/Tyr (15/50,30%). Through genealogical study, 31 MTC patients were found descendants of one family of Jewish Moroccan descent, accounting for 27/28 patients with documented Cys618Arg mutation and 4 patients without available genetic testing. Familial Cys618Arg cases (n=31) and Cys634Arg/Thr/Tyr cases (n=15, from 6 families) were compared. Although surgical age was similar (25.7 vs 31.3 years, p=0.19), the Cys618Arg group had smaller tumors (8.9mm vs 18.5mm, p=0.004) and lower calcitonin levels (33.9 vs 84.5 X/ULN, p=0.03). Youngest ages at MTC diagnosis were 8 and 3 years in Cys618Arg and Cys634Arg/Thr/Tyr cohorts, respectively. Long-term outcome was similar between groups. The Cys618Arg cohort had lower rates of pheochromocytoma (6.5% vs 53.3%, p=0.001) and primary hyperparathyroidism (3.2% vs 33.3%, p=0.01).ConclusionThis is the first description of RET mutation distribution in Israel. Of 131 tested MTC patients, Cys618Arg was the predominant mutation. To the best of our knowledge, this is the largest cohort of Cys618Arg mutation described. For Cys618Arg and Cys634Arg/Thr/Tyr cohorts, MTC was diagnosed earlier than expected, likely due to familial genetic screening, and MTC outcomes were similar between groups. International studies are necessary to further characterize the clinical features of Cys618 mutations due to their relative rarity
