These findings suggest that self-injury serves a function in emotion regulation and the communication of distress. The results also have implications for practice Maladaptive perfectionism should be assessed as a risk factor for NSSI, and teaching mindfulness may be an effective intervention for adolescents who engage in this high-risk behavior.
Age can affect hand muscles non-uniformly. We investigated the influence of age on the compound muscle action potential (CMAP) amplitude of the hand muscles and the derived split-hand index (SHI).

We studied 244 subjects investigated for suspected myasthenia gravis but without neuromuscular disorders. Abductor pollicis brevis (APB), first dorsal interosseous (FDI), and abductor digiti minimi (ADM) CMAPs were obtained by supramaximal stimulation at the wrist, recording with surface electrodes while checking the best recording site. We applied Tukey's HSD and Kruskal-Wallis one-way analysis of variance for comparing age groups defined by median and interquantile ranges (IQRs). Spearman's rank correlation coefficient and linear regression were used for testing age-dependence of measurements.

Median age was 61.5y (first IQR, 44.5; third IQR, 72.0; range 18-89). Age and neurophysiological measurements were similar between genders. APB
, FDI
, ADM
, and SHI were correlated with age (P< .001). Median and cutoff values were significantly different between age groups. APB
, FDI
, and ADM
decreased by 0.8/0.7/0.3mV/y, respectively, and SHI decreased 0.15/y.

The CMAP amplitudes of hand muscles and derived SHI were strongly age-dependent, although this effect was less in ADM. This represents a physiological phenomenon. Future studies using the SHI should consider age effects.

To assess knowledge among neurologists in Sweden and Norway on the restrictions issued by the European Medicines Agency (EMA) regarding use of valproic acid (VPA) to female patients of childbearing potential, their use of the pregnancy prevention programme and their VPA prescription habits.

We conducted an online survey from May through September 2021 inviting neurologists in Sweden and Norway to participate. The questions assessed familiarity with the EMA restrictions, knowledge and use of the information material issued by Market Authorization Holders (MAH) of VPA, and experience of VPA prescriptions to women of childbearing age in the last 2years.

The survey received 202 responses (response rate≈20%). Of the responders, 51% were well acquainted with the EMA restrictions, and 49% were aware of the MAH-issued educational material. Eighty-eight (44%) had prescribed VPA to women of childbearing age in the last 2years, and of these, only a small minority (n=13) regularly used the information brochure for patients, and even fewer (n=8) the VPA risk acknowledgement forms.

We found limited penetrance of the new EMA restrictions on VPA use as well as limited acceptance and use among prescribers of the current company-issued information material and risk acknowledgment forms. More information campaigns and closer collaboration with treating physicians are likely needed.

Hypotheses were tested using actor-partner interdependence models with a sample of 543 cisgender sexual minority male couples. Results showed both partners' enacted stigma experiences were associated with elevated levels of internalized homophobia via actor and partner effects. Internalized homophobia was only associated with elevated depressive symptoms via actor effects. Indirect effects analysis suggested that internalized homophobia mediated the actor and partner influence of enacted stigma on depressive symptoms. Communal coping moderated the direct effects of enacted stigma on internalized homophobia and attenuated the conditional indirect actor and partner effects of enacted stigma on depressive symptoms. Findings underscore the role of intimate relationship processes in understanding the impacts of enacted stigma on depressive symptoms.
This study investigated whether moral injury appraisals moderated the relationships between trauma, postmigration living difficulties, resilience, and mental health outcomes in adolescent refugees.

Eighty-five adolescent refugees from a community sample completed an online survey.

A significant interaction was found between moral injury and discrimination for externalizing and posttraumatic stress disorder (PTSD) symptoms; adolescents whom had experienced high levels of discrimination combined with high levels of moral injury had poorer mental health. A significant interaction was found between moral injury and resilience for internalizing symptoms high levels of resilience appeared to buffer the association between moral injury and internalizing symptoms. Contrary to predictions, stressful life experiences and postmigration living difficulties did not interact significantly with moral injury to predict mental health.

Discrimination may contribute to perpetuating poor mental health in adolescent refugees with high levels of moral injury. Resilience may buffer some of the negative effects of moral injury.

Atopic dermatitis (AD) is characterized by immune dysregulations and an impaired skin barrier, including abnormalities in lipid organization. In the stratum corneum (SC), β-glucocerebrosidase (GBA) mediates transformation of glucosylceramide (GlcCER) into ceramide (CER) and cholesterol into glucosylcholesterol (GlcChol). Alteration in GBA activity might contribute to skin barrier defects in AD.

To investigate GBA activity in the SC of children with AD before and after topical corticosteroid therapy and to compare it with healthy controls; to determine SC levels of GlcCER- and CER-containing hydroxysphingosine base (GlcCER[H] and CER[H], respectively) and GlcChol; and to relate them to disease severity, skin barrier function and the local cytokine milieu.

Lipid markers and cytokines of innate, T helper 1 and T helper 2 immunity were determined in SC collected from healthy children and from clinically unaffected skin of children with AD, before and after 6 weeks of therapy with topical corticosteroids. ADn lipid metabolism in the stratum corneum of infants with AD.Secondary prevention is a set of procedures involved in discovering early recurrence, local or systemic metastasis before the clinical signs or symptoms. We describe a mouse model with orthotopic pancreatic tumor implantation followed by distal pancreatectomy. The bioluminescence imaging and MRI could be used for screening the resected primary tumor recurrence and secondary cancer development. Different types of surgical procedures, chemotherapy, or immunotherapy can be engaged in reducing the metastasis potential of primary cancers. This model has been proved to be safe and easy to establish, which can mimic the clinical scenario and expand perspectives for studying the effects of tumor resection and adjuvant or neoadjuvant therapy on secondary cancer prevention.Lung cancer is the second most common cancers in the world and remains as the cancer with the highest incidence of death (Siegel et al. CA Cancer J Clin 71(1)7-33, 2021). K-RAS mutation is one of the most common mutations in non-small-cell lung cancer (NSCLC), encompassing 15-30% of lung adenocarcinomas (Cancer Genome Atlas Research Network. Nature 511543-550, 2014). In this chapter, we describe various murine models with the goal of studying the role of inflammation in development and promotion of lung cancer. Immunomodulatory strategies are described in detail as well as the protocols that follow the intervention for harvesting various tissue and fluids for immune-profiling.Obesity is a major risk factor for the development of multiple cancers. see more In efforts to develop models that will assist the scientific community in studying the mechanisms of this risk, a diet-induced obesity model of obesity is often utilized. Here we describe the use of diet-induced obesity (DIO) diets to study the effects of high-fat diet weight gain in the context of cancer mouse models.The process of cellular transformation involves acquisition of genetic mutations that disrupt parenchymal organization and promote unrestrained epithelial cell proliferation. In the context of transformation, recent advances using genetic lineage tracing have enabled scientists to study the behavior of neoplastic cells in their native habitat. Employing lineage tracing to understand mechanisms of transformation, including cell type-specific responses to inflammation, is an empirical method to use in the field of cancer prevention. Identifying new approaches to prevent cancer formation can be directly studied by indelibly labeling cells to trace their fate and understand at a molecular level how they respond to novel methods for testing cancer preventing agents.There is an unmet need for noninvasive surrogate markers that can help identify premalignant lesions across different tumor types. Here we describe the methodology and technical details of protocols employed for in vivo 13C pyruvate metabolic imaging experiments. The goal of the method described is to identify and understand metabolic changes, to enable detection of pancreatic premalignant lesions, as a proof of concept of the high sensitivity of this imaging modality.The tumor microenvironment forms a complex pro-tumorigenic milieu constituted by extracellular matrix, surrounding stroma, infiltrating cell populations, and signaling molecules. Proteomic studies have the potential to reveal how individual cell populations within the tumor tissue modulate the microenvironment through protein secretion and consequently alter their protein expression and localization to adapt to this milieu. As a result, proteomic approaches have uncovered how these dynamic components communicate and promote tumor development and progression. The characterization of these mechanisms is relevant for the identification of clinically targetable pathways and for the development of diagnostic tools. Here we describe a method based on the isolation of individual cell compartments and the chromatographic fractionation of intact proteins, followed by enzymatic digestion of individual fractions, and mass-spectrometry analysis, for the profiling of tumor microenvironment cell populations.
