Developmental antecedents of autism may affect parent-infant interactions (PII), altering the context in which core social skills develop. While studies have identified differences in PII between infants with and without elevated likelihood (EL) for autism, samples have been small. Here, we examined whether previously reported differences are replicable. From a longitudinal study of 113 EL and 27 typical likelihood infants (TL), 6-min videotaped unstructured PII was blind rated at 8 and 14 months on eight interactional qualities. Autism outcome was assessed at 36 months. Linear mixed-effects models found higher parent sensitive responsiveness, nondirectiveness, and mutuality ratings in TL than EL infants with and without later autism. PII qualities at 8 (infant positive affect, parent directiveness) and 14 months (infant attentiveness to parent, mutuality) predicted 3-year autism. Attentiveness to parent decreased between 8 and 14 months in EL infants with later autism. This larger study supports previous findings of emerging alterations in PII in this group and extends on this by detecting earlier (8-month) predictive effects of PII for autism outcome and a more marked trajectory of decreased social attentiveness. The findings strengthen the evidence base to support the implementation of early preemptive interventions to support PII in infants with early autism signs.

Review
The NAA10 gene encodes N-alpha-acetyltransferase 10 which plays an important role in cell growth, differentiation, DNA damage, metastasis, apoptosis, stress response and autophagy. Defects in the NAA10 gene correlate with the diagnosis of NAA10-related syndrome (Ogden syndrome). The most common symptoms of NAA10-related syndrome are: global developmental delay, non-verbal or limited speech, autism spectrum disorder, feeding difficulties, motor delay, muscle tone disturbances, and long QT syndrome. To-date, there are about 100 patients who have been reported with this condition. The case report presents the clinical study of a girl aged 4 years and 3 months diagnosed with Ogden syndrome. She had many characteristic features of the disorder, as well as precocious puberty. This girl represents the case of a patient with p.Arg83Cys mutation in NAA10 gene as well as precocious puberty.

Review
This article explores the potential therapeutic implications of phytochemicals on the gut-brain axis (GBA), which serves as a communication network between the central nervous system and the enteric nervous system. Phytochemicals, which are compounds derived from plants, have been shown to interact with the gut microbiota, immune system, and neurotransmitter systems, thereby influencing brain function. Phytochemicals such as polyphenols, carotenoids, flavonoids, and terpenoids have been identified as having potential therapeutic implications for various neurological disorders. The GBA plays a critical role in the development and progression of various neurological disorders, including Parkinson's disease, multiple sclerosis, depression, anxiety, and autism spectrum disorders. Dysbiosis, or an imbalance in gut microbiota composition, has been associated with a range of neurological disorders, suggesting that modulating the gut microbiota may have potential therapeutic implications for these conditions. Although these findings are promising, further research is needed to elucidate the optimal use of phytochemicals in neurological disorder treatment, as well as their potential interactions with other medications. The literature review search was conducted using predefined search terms such as phytochemicals, gut-brain axis, neurodegenerative, and Parkinson in PubMed, Embase, and the Cochrane library.

Traumatic childhood events are some of the few identifiable and to some extent preventable causes of psychiatric illness. Children exposed to severely stressful events may react with post-traumatic stress disorder (PTSD) and this may impact their level of function in daily life, their future development and mental health. The traumatic stress model suggests that traumatic stress in the family, community violence, and other traumas are regarded as additive environmental factors that can outweigh protective compensatory factors and thus interact with individual vulnerabilities. This study is based on prospective panel data including the whole population of children born in Denmark from 1984 to 1994, who are followed from age 7 to age 18 (N = 679,000) in the window between 2001 and 2012. Risk factors for first-time diagnose with PTSD are analyzed by the discrete time log-odd model. We found a lifetime prevalence of 2.3% PTSD in school-age children (n = 15,636). In accordance with the model, indicators of traumatic stress in the family, family disintegration, community violence, and individual vulnerabilities predicted later diagnose with PTSD. Individual neurodevelopmental disorder - especially autism (adjusted Odds Ratio (OR 7.1) and ADHD (OR 10.7) - were predicative of PTSD. The results cooperated the traumatic stress model. Some results were inconsistent with the traumatic stress model e.g., parental substance abuse were associated with less than expected PTSD in school-age children when adjusted for other risk factors. This indicates that PTSD may be underestimated in these groups. PTSD diagnoses in administrative records underestimate the prevalence, systematically. Efforts to increase PTSD screening may allow for better management.

Review
There is a reported high prevalence of anxiety in people with autism spectrum disorder. This mini review appraises existing research investigating heart rate variability biofeedback to help manage symptoms of anxiety in people with autism spectrum disorder. A thorough search of electronic databases was conducted to find relevant literature. Consultation with experts and a librarian helped develop search terms following the PICO framework. Five databases were searched, and screening was undertaken using Covidence software, with the process outlined in a PRISMA flowchart. The latest review showed positive short-term effects but there is a need for long-term follow-up. Future investigations should consider device type, training settings, and control interventions. Accurate heart rate variability assessment independent of biofeedback devices is crucial. Additional measures like cortisol assessment and user feedback are recommended for comprehensive evaluation. The findings highlight progress in the evidence base and offer insight to future directions.

INTRODUCTION
The mobile health application "Stress Autism Mate" (SAM) was designed to support adults with autism in identifying and managing daily stress. SAM measures stress four times daily, provides a daily and weekly stress overview, and provides personalised stress reduction advice. This study aimed to assess the effectiveness of SAM over four weeks in reducing perceived stress and internalised stigma, and enhancing coping self-efficacy, quality of life, and resilience among adults with autism.
METHODS
Using an A1-B-A2 single-case experimental design, the effect of using SAM on adults with autism was assessed. The phases consisted of A1; treatment as usual (TAU), B; introducing SAM, and finally A2; follow-up with TAU and without the use of SAM. Each phase lasted four weeks, and data were collected via questionnaires before and after each phase. Linear mixed models were used for data analysis.
RESULTS
Results show significant reductions in perceived stress levels, increased coping self-efficacy, and improved perceived health and psychological well-being after using SAM. Furthermore, increased resilience, and decreased internalised stigma were reported after follow-up.
DISCUSSION
In conclusion, this study highlights SAM as a valuable tool for empowering adults with autism to reduce stress and internalised stigmaand to improve coping self-efficacy, psychological well-being, and resilience.

INTRODUCTION
Although memory challenges in autistic individuals have been characterized recently, the functional connectivity of the hippocampus and ventral temporal lobe, two structures important for episodic and semantic memory functions, are poorly understood in autistic individuals. Moreover, age-related differences in the functional connectivity associated with these two memory networks are unrevealed.
METHODS
The current study investigated age-related differences in intrinsic connectivity of the hippocampal and ventral temporal lobe (vTL) memory networks in well-matched ASD ( = 73; age range: 10.23-55.40 years old) and Non-ASD groups ( = 74; age range: 10.46-56.20 years old) from the open dataset ABIDE-I. Both theory-driven ROI-to-ROI approach and exploratory seed-based whole-brain approach were used.
RESULTS AND DISCUSSION
Our findings revealed reduced connectivity in ASD compared to Non-ASD peers, as well as an age-related reduction in the connectivity of hippocampal and vTL networks with triple networks, namely, the default mode network (DMN), the central executive network (CEN), and the salience network (SN), potentially underpinning their challenges in memory, language, and social functions. However, we did not observe reliable differences in age-related effects between the ASD and Non-ASD groups. Our study underscores the importance of understanding memory network dysfunctions in ASD across the lifespan to inform educational and clinical practices.

Review
Autism spectrum disorder (ASD) is a common neurodevelopmental disorder, that affects both pediatric and adult populations and presents heterogeneously. The understanding of the clinical characteristics of ASD has expanded, in parallel with societal developments, including the integration of the notion of gender in medicine. It appears that individuals affected by this disorder, regardless of their age, are neither detected, diagnosed, nor followed or treated in the same manner depending on their gender. This article proposes to review current knowledge on ASD, its expression based on gender, factors influencing care, and the consequences for patients of exposure to gender bias.
