Modulation of human corticospinal excitability by paired associative stimulation in patients with amyotrophic lateral sclerosis and effects of Riluzole

BACKGROUND Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that causes an impairment in both the upper and lower motor neurons. The recent description of numerous non-motor signs points to an involvement of the neocortex networks that is more complex than was previously believed. Paired associative stimulation (PAS), a combination of transcranial magnetic stimulation (TMS) and peripheral nerve stimulation, can enhance motor output in the contralateral hand through an NMDA-mediated sensorimotor mechanism. OBJECTIVE To describe the effects of PAS on ALS patients before and after Riluzole intake compared with healthy subjects. METHODS PAS was used to detect differences between 24 newly-diagnosed ALS patients and 25 age-matched healthy controls. MEP amplitude from the abductor pollicis brevis was considered before PAS, immediately after (T0) and after 10 (T10), 20 (T20), 30 (T30) and 60 (T60) minutes. Statistical significance was calculated using RM-ANOVA. RESULTS In healthy controls, PAS significantly increased MEP amplitude at T10, T20 and T30 (p < 0.05). In ALS patients, a significant increase in MEP amplitude was also observed after 60 min (p < 0.05), thus demonstrating NMDA-mediated enhanced facilitatory plasticity. After two weeks of riluzole intake, no MEP amplitude increase was evident after PAS at any time point. In three monomelic-onset ALS patients, sensorimotor facilitation was evident only in the hemisphere corresponding to the affected side and appeared in the opposite hemisphere when the patients manifested contralateral symptoms. CONCLUSIONS PAS may be considered a useful tool when investigating NMDA-mediated neocortical networks in ALS patients and the modulation of such networks after anti-glutamatergic drug intake

Gender Felt Pressure, Affective Domains, and Mental Health Outcomes among Transgender and Gender Diverse (TGD) Children and Adolescents: A Systematic Review with Developmental and Clinical Implications

Although capable of mobilizing significant resilience factors to face stigma and discrimination, transgender and gender diverse (TGD) children and adolescents tend to suffer from more adverse mental health outcomes compared to their cisgender counterparts. The minority stressors that this population faces are mainly due to the gender-based pressure to conform to their assigned gender. This systematic review was aimed at assessing the potential mental health issues that affect the TGD population. The literature search was conducted in three databases; namely, Scopus, PubMed, and Web of Science, based on the PRISMA guidelines. The 33 articles included in the systematic review pointed out how TGD children and adolescents experience high levels of anxiety and depression, as well as other emotional and behavioral problems, such as eating disorders and substance use. Resilience factors have been also pointed out, which aid this population in facing these negative mental health outcomes. The literature review highlighted that, on the one hand, TGD individuals appear to exhibit high levels of resilience; nonetheless, health disparities exist for TGD individuals compared with the general population, which are mainly attributable to the societal gender pressure to conform to their assigned gender. Considerations for research and clinical practice are provided

“Under house arrest”: mental health and minority stress experiences of LGBTQ+ young adults during the COVID-19 pandemic in Europe

Introduction: Increased rates of mental health issues among LGBTQ+ people have been reported during the COVID-19 pandemic, particularly among young people. Method: Semi-structured interviews were conducted 2021 with 61 young adult LGBTQ+ people residing in France, Italy, Portugal, Sweden, and the UK. Each interview was summarized on a template covering the participants’ experiences of pandemic restrictions, mental health, and minority stress during this period. A thematic analysis was conducted on the templates. Results: The pandemic restrictions had a large impact on the participants’ lives, leaving them stuck at home. Not having access to the LGBTQ+ community was an additional stress, as this is a venue for support. Half of the participants had suffered from mental health issues during the pandemic. Those who were living in non-affirmative households had a particularly difficult time and experienced overwhelming stress. Increased feelings of gender dysphoria were seen among trans participants due to lack of access to gender affirming healthcare. Most participants experienced less distal minority stress than usual due to social isolation restrictions. Conclusion: The COVID-19 pandemic and the associated social restrictions had a large impact on the lives of LGBTQ+ young adults. Many experience worse mental health, although a relief from distal minority stress was common. Policy implications: Policy makers must consider the needs of LGBTQ+ young adults as they seek to explore and establish their gender and/or sexual identity. During a pandemic, it is particularly important to help young LGBTQ+ people to engage with the LGBTQ+ community

Psychological Adjustment Profiles of LGBTQ+ young adults residing with their parents during the COVID-19 pandemic: an international study

The COVID-19 pandemic has been associated with poor mental health symptoms, particularly among vulnerable populations such as LGBTQ+ individuals. In the present study, we aimed to (i) identify different psychological adjustment profiles among LGBTQ+ young adults during the COVID-19 pandemic and compare LGBTQ+ young adults in relation to (ii) sociodemographic characteristics and COVID-19-related experiences and (iii) the internal and external protective resources associated with each adjustment profile. An online questionnaire was administered to 1699 LGBTQ+ young adults from six countries (Brazil, Chile, Italy, Portugal, Sweden, and the UK). A cluster analysis was conducted, and four profiles of psychological adjustment were identified: unchallenged, resilient, distressed, and at-risk. The at-risk cluster scored lowest in social support (particularly from family). The profiles of participants who experienced the highest levels of pandemic adversity (at-risk and resilient) comprised mostly South American participants, those under lockdown at the time of survey completion, those who self-identified as transgender and non-binary, and those with a plurisexual sexual orientation. Interventions should consider strategies to help young adults maintain support systems and reinforce the value of positive family relationships. Specific groups within the LGBTQ+ community that seem to be in a particularly vulnerable situation may need additional tailored support

Bone health and body composition in transgender adults before gender-affirming hormonal therapy: data from the COMET study

Purpose: Preliminary data suggested that bone mineral density (BMD) in transgender adults before initiating gender-affirming hormone therapy (GAHT) is lower when compared to cisgender controls. In this study, we analyzed bone metabolism in a sample of transgender adults before GAHT, and its possible correlation with biochemical profile, body composition and lifestyle habits (i.e., tobacco smoke and physical activity). Methods: Medical data, smoking habits, phospho-calcic and hormonal blood tests and densitometric parameters were collected in a sample of 125 transgender adults, 78 Assigned Females At Birth (AFAB) and 47 Assigned Males At Birth (AMAB) before GAHT initiation and 146 cisgender controls (57 females and 89 males) matched by sex assigned at birth and age. 55 transgender and 46 cisgender controls also underwent a complete body composition evaluation and assessment of physical activity using the International Physical Activity Questionnaire (IPAQ). Results: 14.3% of transgender and 6.2% of cisgender sample, respectively, had z-score values < -2 (p = 0.04). We observed only lower vitamin D values in transgender sample regarding biochemical/hormonal profile. AFAB transgender people had more total fat mass, while AMAB transgender individuals had reduced total lean mass as compared to cisgender people (53.94 ± 7.74 vs 58.38 ± 6.91, p < 0.05). AFAB transgender adults were more likely to be active smokers and tend to spend more time indoor. Fat Mass Index (FMI) was correlated with lumbar and femur BMD both in transgender individuals, while no correlations were found between lean mass parameters and BMD in AMAB transgender people. Conclusions: Body composition and lifestyle factors could contribute to low BMD in transgender adults before GAHT

Profiles of Parental Burnout Around the Globe: Similarities and Differences Across 36 Countries

Parental burnout (PB) is a pervasive phenomenon. Parenting is embedded in cultural values, and previous research has shown the role of individualism in PB. In this paper, we reanalyze previously collected data to identify profiles based on the four dimensions of PB, and explore whether these profiles vary across countries' levels of collectivistic-individualistic (COL-IND) values. Our sample comprised 16,885 individuals from 36 countries (73% women; 27% men), and we used a latent profile approach to uncover PB profiles. The findings showed five profiles: Fulfilled, Not in PB, Low risk of PB, High risk of PB and Burned out. The profiles pointed to climbing levels of PB in the total sample and in each of the three country groups (High COL/Low IND, Medium COL-IND, Low COL/High IND). Exploratory analyses revealed that distinct dimensions of PB had the most prominent roles in the climbing pattern, depending on the countries' levels of COL/IND. In particular, we found contrast to be a hallmark dimension and an indicator of severe burnout for individualistic countries. Contrary to our predictions, emotional distance and saturation did not allow a clear differentiation across collectivistic countries. Our findings support several research avenues regarding PB measurement and intervention

Parenting Culture(s): Ideal-Parent Beliefs Across 37 Countries

What is it to be “an ideal parent”? Does the answer differ across countries and social classes? To answer these questions in a way that minimizes bias and ethnocentrism, we used open-ended questions to explore ideal-parent beliefs among 8,357 mothers and 3,517 fathers from 37 countries. Leximancer Semantic Network Analysis was utilized to first determine parenting culture zones (i.e., countries with shared ideal-parent beliefs) and then extract the predominant themes and concepts in each culture zone. The results yielded specific types of ideal-parent beliefs in five parenting culture zones: being “responsible and children/family-focused” for Asian parents, being “responsible and proper demeanor-focused” for African parents, and being “loving and responsible” for Hispanic-Italian parents. Although the most important themes and concepts were the same in the final two zones—being “loving and patient,” there were subtle differences: English-speaking, European Union, and Russian parents emphasized “being caring,” while French-speaking parents valued “listening” or being “present.” Ideal-parent beliefs also differed by education levels within culture zones, but no general pattern was discerned across culture zones. These findings suggest that the country in which parents were born cannot fully explain their differences in ideal-parent beliefs and that differences arising from social class or education level cannot be dismissed. Future research should consider how these differences affect the validity of the measurements in question and how they can be incorporated into parenting intervention research within and across cultures

Parental Burnout Around the Globe: a 42-Country Study

High levels of stress in the parenting domain can lead to parental burnout, a condition that has severe consequences for both parents and children. It is not yet clear, however, whether parental burnout varies by culture, and if so, why it might do so. In this study, we examined the prevalence of parental burnout in 42 countries (17,409 parents; 71% mothers; M_{age} = 39.20) and showed that the prevalence of parental burnout varies dramatically across countries. Analyses of cultural values revealed that individualistic cultures, in particular, displayed a noticeably higher prevalence and mean level of parental burnout. Indeed, individualism plays a larger role in parental burnout than either economic inequalities across countries, or any other individual and family characteristic examined so far, including the number and age of children and the number of hours spent with them. These results suggest that cultural values in Western countries may put parents under heightened levels of stress
