The One Hour Human Proteome.

We describe deep analysis of the human proteome in less than 1 h. We achieve this expedited proteome characterization by leveraging state-of-the-art sample preparation, chromatographic separations, and data analysis tools, and by using the new Orbitrap Astral mass spectrometer equipped with a quadrupole mass filter, a high-field Orbitrap mass analyzer, and an asymmetric track lossless (Astral) mass analyzer. The system offers high tandem mass spectrometry acquisition speed of 200 Hz and detects hundreds of peptide sequences per second within data-independent acquisition or data-dependent acquisition modes of operation. The fast-switching capabilities of the new quadrupole complement the sensitivity and fast ion scanning of the Astral analyzer to enable narrow-bin data-independent analysis methods. Over a 30-min active chromatographic method consuming a total analysis time of 56 min, the Q-Orbitrap-Astral hybrid MS collects an average of 4319 MS1 scans and 438,062 tandem mass spectrometry scans per run, producing 235,916 peptide sequences (1% false discovery rate). On average, each 30-min analysis achieved detection of 10,411 protein groups (1% false discovery rate). We conclude, with these results and alongside other recent reports, that the 1-h human proteome is within reach.

A global systematic scoping review of literature on the sexual exploitation of boys.

BACKGROUND: Sexual exploitation of children (SEC) is a widespread crime which impacts the child victim across developmental, health and well-being domains. As victims, boys have received much less clinical and research attention. While context-specific factors likely shape the SEC risk, under-recognized gender norms can deny boys' vulnerability. Professional failures to recognize and respond adequately to boys' sexual exploitation may prevent access to support. OBJECTIVE: This systematic scoping review updates and broadens a previous review of literature addressing prevalence, victim/offender/facilitator characteristics, control mechanisms, as well as the health correlates and outcomes regarding sexual exploitation of boys. This review included international peer-reviewed and gray literature from 38 countries in 14 languages. PARTICIPANTS AND SETTING: Studies from the years 2000 to 2022 that included samples of boys under age 18, or sex-disaggregated data for children under 18, were included. Case studies, systematic reviews, and those reporting on retrospective experiences by adults over 18 were excluded. A total of 254,744 boys were represented across 81 studies. METHODS: A systematic scoping review considered qualitative and quantitative peer-reviewed publications from eight, English-language databases. English and non-English non-peer reviewed publications ('gray literature') was identified by both ECPAT International's global network of member organizations and citation chaining. RESULTS: Overall, 81 peer-reviewed (n = 51) and gray literature (n = 30) documents from 38 countries were included. In total, 254,744 youth participated in peer-reviewed studies (N = 217,726) and gray literature (N = 37,018). General prevalence of sexual exploitation of boys was reported at up to 5 %, with higher rates noted in specifically vulnerable sub-populations (e.g., 10 %, trans youth; 26 %, street-connected youth). The literature indicates that sexual exploitation of boys is reported as occurring primarily between 12 and 18 years old. Multi-level factors are linked to SEC, including individual (e.g., disability status), relationship (e.g., child maltreatment, dating violence), community (e.g., community violence), and societal domains (e.g., discriminatory beliefs). SEC victimization is linked with youth mental and physical health concerns, particularly sexual health. Post-traumatic stress symptomatology or disorder was rarely evaluated. Evidence-based treatments were not available, which may be related to a lack of gender-based theoretical models for understanding SEC specifically. CONCLUSION: The sexual exploitation of boys is a prevalent public health, child rights, and clinical issue. All young people experiencing sexual exploitation face sex- and gender-specific challenges, and this remains the case for boys with indications including family rejection, implicit community tolerance for abuse to service accessibility barriers. Actioning our duty to care for all children requires gender- and trauma-informed lenses. Ongoing surveillance of all forms of violence against children, with gender disaggregation, is essential for practice and policy advancement.

Distinct Metabolic States Are Observed in Hypoglycemia Induced in Mice by Ricin Toxin or by Fasting.

Hypoglycemia may be induced by a variety of physiologic and pathologic stimuli and can result in life-threatening consequences if untreated. However, hypoglycemia may also play a role in the purported health benefits of intermittent fasting and caloric restriction. Previously, we demonstrated that systemic administration of ricin toxin induced fatal hypoglycemia in mice. Here, we examine the metabolic landscape of the hypoglycemic state induced in the liver of mice by two different stimuli: systemic ricin administration and fasting. Each stimulus produced the same decrease in blood glucose and weight loss. The polar metabolome was studied using 1H NMR, quantifying 59 specific metabolites, and untargeted LC-MS on approximately 5000 features. Results were analyzed by multivariate analyses, using both principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA), to identify global metabolic patterns, and by univariate analyses (ANOVA) to assess individual metabolites. The results demonstrated that while there were some similarities in the responses to the two stimuli including decreased glucose, ADP, and glutathione, they elicited distinct metabolic states. The metabolite showing the greatest difference was O-phosphocholine, elevated in ricin-treated animals and known to be affected by the pro-inflammatory cytokine TNF-α. Another difference was the alternative fuel source utilized, with fasting-induced hypoglycemia primarily ketotic, while the response to ricin-induced hypoglycemia involves protein and amino acid catabolism.

Child Maltreatment and the Child Welfare System as Environmental Factors in the International Classification of Functioning.

The WHO defines child maltreatment as any form of neglect, exploitation, and physical, emotional, or sexual abuse, committed against children under the age of 18. Youth involved in the child welfare system report more maltreatment experiences and environmental turbulence (e.g., number of moves, caseworkers), placing them at greater risk for poorer physical and mental health. The International Classification of Functioning, Disability, and Health (ICF) provides a framework to describe health conditions and severity of disabilities for an individual and/or group in the context of environmental factors. The Maltreatment and Adolescent Pathways (MAP) study is a longitudinal study, assessing self-reports on variables (e.g., child maltreatment history, trauma symptoms, dating violence, and substance use) of youth in an urban child protection service system. This study focuses on 11 of the 24 MAP publications that pertain to health and functioning, which can be considered applicable to the ICF framework, following established linking rules. The purpose of this study is to analyze these MAP sub-studies, with maltreatment and involvement in the child welfare system as environmental factors that impact the functioning of child welfare-involved youth. Findings indicate significant relationships across environmental factors (i.e., child maltreatment histories, child welfare system involvement), health conditions (i.e., trauma symptomatology, psychological distress, intellectual disabilities), and functioning problems (i.e., substance use, adolescent dating violence, sexual risk-taking, coping motives, sleep problems). The interrelated nature of these factors in the MAP sub-studies suggests the value of the ICF model to a holistic health view of use to practitioners supporting system-involved youth, clarifying unattended environmental factors in guiding service provision for foster care and/or maltreated youth.

Effect of alcohol skin cleansing on vaccination-associated infections and local skin reactions: a randomized controlled trial.

OBJECTIVES: Recommendations regarding the need to use alcohol prior to vaccine injections are inconsistent and based on low-level evidence. The objective was to assess the effectiveness of alcohol in reducing local skin reactions and infection post-vaccination. METHODS: Randomized controlled trial in a pediatric clinic. A research assistant cleansed the skin with alcohol at (swab group) or adjacent to (control group) the pre-defined injection site(s). Clinicians, parents and children were blinded to group allocation. Parents reported local skin reactions using paper diaries for 15 days post-vaccination (Day 0-14). Telephone interviews were conducted Day 1, 5, and 14. The Brighton Collaboration criteria were used to diagnose cellulitis and infectious abscess Day 5 and afterward. RESULTS: 170 children participated (May-November 2017). Baseline characteristics did not differ (p > 0.05) between groups. Children received 1-4 separate injections. There were no differences between swab and control groups in the incidence of any local skin reactions (58% vs. 54%), and specifically, pain (45% vs. 40%), redness (26% vs. 21%), swelling (20% vs. 13%), warmth (19% vs. 27%), and spontaneous drainage of pus (0% in both groups) over the post-vaccination follow-up period. Day 5 data was available for 99% of participants from diaries and telephone surveys; there were no cases of cellulitis or infectious abscess. CONCLUSION: These findings are the first direct evidence for vaccine injections demonstrating that cleansing the skin with alcohol may not be needed. Our study is underpowered; however, to detect a difference in incidence of skin infection, future research is recommended.
