    Abstract The Health and Environmental Sciences Institute Developmental and Reproductive Toxicology (HESI-DART) group held a hybrid in-person and virtual workshop in Washington, DC, in 2022. The workshop was entitled, "Interpretation of DART in Regulatory Contexts and Frameworks." There were 154 participants (37 in person and 117 virtual) across 9 countries. The purpose of the workshop was to capture key consensus approaches used to assess DART risks associated with chemical product exposure when a nonclinical finding is identified. The decision-making process for determining whether a DART endpoint is considered adverse is critical because the outcome may have downstream implications (e.g., increased animal usage, modifications to reproductive classification and pregnancy labeling, impact on enrollment in clinical trials and value chains). The workshop included a series of webinar modules to train and engage in discussions with federal and international regulators, clinicians, academic investigators, nongovernmental organizations, contract research organization scientists, and private sector scientists on the best practices and principles of interpreting DART and new approach methodologies in the context of regulatory requirements and processes. Despite the differences in regulatory frameworks between the chemical and pharmaceutical sectors, the same foundational principles for data interpretation should be applied. The discussions led to the categorization of principles, which offer guidance for the systematic interpretation of data. Step 1 entails identifying any hazard by closely analyzing the data at the study endpoint level, while Step 2 involves assessing risk using weight of evidence. These guiding principles were derived from the collective outcomes of the workshop deliberations.

    Abstract The ongoing outbreak of the monkeypox virus (now referred to as "mpox") was deemed a public health emergency by the World Health Organization in 2022. The United States now reports the highest number of mpox cases, with 29 980 cases and 21 deaths as of January 11, 2023. The most common presenting symptom is a pruritic, vesicular rash that commonly involves the hands. While covering hand call, our division has encountered 2 cases of mpox in the emergency department for which the chief complaint was a hand lesion. Because hand surgeons will be called upon to make an initial diagnosis, the purpose of these case reports is to describe the presentation, disease course, treatment, and outcomes of these mpox patients. These patients had both uncontrolled HIV as well as other sexually transmitted disease. Symptoms included painful vesicular hand lesions with ulceration and eventual central necrosis, followed by similar lesions on the face, trunk, and genital area. Diagnosis was made using nucleic acid amplification testing through polymerase chain reaction. The patients were treated with restoration of immunity through control of HIV as well as treatment of all secondary bacterial infections. One patient died in the hospital, and the other survived without any long-term defects.

    Abstract Background: Diversity in leadership drives innovation; however, women are underrepresented in leadership positions across academic medicine. The aim of this study was to assess the current gender representation in hand surgery leadership positions.
    Methods: This was a cross-sectional analysis of leaders in hand surgery. Leaders were defined as President, Board and Committee members of the American Society for Surgery of the Hand and the American Association for Hand Surgery, as well as hand surgery fellowship program directors and physician lead editors of peer-reviewed hand journals. The representation of women in leadership was compared to the percentage of female hand fellows over the same period. Years in practice, academic rank, additional degrees,
    Results: Twenty-nine of 213 leadership positions (13.6%) are held by women which is fewer than would be expected based on hand surgery fellowship composition. Female leaders were earlier in practice than their male counterparts (13.5 ± 5.7 versus 20.8 ± 11.1 years,
    Conclusions: Gender disparities in hand surgery exist and are accentuated at the leadership level. Further work is needed to decrease leadership promotion disparities between men and women.

    Abstract Inflammatory bowel disease (IBD), which includes both Crohn disease and ulcerative colitis, is a relapsing inflammatory disease of the gastrointestinal tract. Long-term chronic inflammatory conditions elevate the patient's risk of colorectal cancer (CRC). Currently, diagnosis requires endoscopy with biopsy. This procedure is invasive and requires a bowel-preparatory regimen, adding to patient burden. Interleukin 12 (IL12) and interleukin 23 (IL23) play key roles in inflammation, especially in the pathogenesis of IBD, and are established therapeutic targets. We propose that imaging of IL12/23 and its p40 subunit in IBD via immuno-PET potentially provides a new noninvasive diagnostic approach.

    Abstract mRNA therapeutics offer a potentially universal strategy for the efficient development and delivery of therapeutic proteins. Current mRNA vaccines include chemically modified nucleotides to reduce cellular immunogenicity. Here, we develop an efficient, high-throughput method to measure human translation initiation on therapeutically modified as well as endogenous RNAs. Using systems-level biochemistry, we quantify ribosome recruitment to tens of thousands of human 5' untranslated regions and identify sequences that mediate 250-fold effects. We observe widespread effects of coding sequences on translation initiation and identify small regulatory elements of 3-6 nucleotides that are sufficient to potently affect translational output. Incorporation of N1-methylpseudouridine (m1Ψ) selectively enhances translation by specific 5' UTRs that we demonstrate surpass those of current mRNA vaccines. Our approach is broadly applicable to dissect mechanisms of human translation initiation and engineer more potent therapeutic mRNAs.
    Highlights: Measurement of >30,000 human 5' UTRs reveals a 250-fold range of translation outputSystematic mutagenesis demonstrates the causality of short (3-6nt) regulatory elementsN1-methylpseudouridine alters translation initiation in a sequence-specific mannerOptimal modified 5' UTRs outperform those in the current class of mRNA vaccines.

    Abstract Distal hereditary motor neuropathy (dHMN) is an inherited neuromuscular disease characterized by symmetric distal weakness and atrophy without sensory changes. There are about thirty known genes associated with dHMN, but together they explain only about a third of cases. Mutations in the sigma non-opioid intracellular receptor 1 gene (SIGMAR1) has been linked to autosomal recessive dHMN with pyramidal signs in several families. This phenotype can mimic amyotrophic lateral sclerosis (ALS). We report a 39-year-old man who was referred to our ALS clinic with distal motor weakness and hyperreflexia. Whole exome sequencing identified two novel variants in the SIGMAR1 gene in the proband. Targeted Sanger sequencing of asymptomatic family members confirmed that each carried one of these two variants. Our findings expand the number of known SIGMAR1 pathogenic variants associated with dHMN, which should be clinically distinguished from ALS.

    Abstract Cigarette gifting is pervasive in China. As the Chinese are increasingly aware of harm from smoking cigarettes, e-cigarettes, often promoted as less harmful alternatives to cigarettes, may be viewed as appropriate gifts. This study is the first using population-based survey data to examine receiving and giving e-cigarettes as gifts in China. We analyzed 9,274 adults from Wave 5 of the International Tobacco Control China Survey, which was completed in July 2015. We found that the prevalence of receiving e-cigarettes as gifts was 1.3% among all respondents and 5.3% among urban smokers; the prevalence of giving e-cigarettes as gifts was 0.5% among all respondents and 1.2% among urban smokers. These prevalence estimates were very low among nonsmokers and rural respondents. Further analysis on urban smokers (N = 3,312) found that those aged 40-54 and 55+, those with high education levels, heavy smokers, and those who perceived e-cigarettes as equally/more harmful than cigarettes were more likely to receive e-cigarette gifts; and those who ever used e-cigarettes were significantly more likely to both receive and give e-cigarette gifts. Urban smokers with positive attitude about cigarette gifting were also more likely to give e-cigarette gifts to others, but those aged 55+ were less likely to gift e-cigarettes. Findings of this study indicate that the Chinese may perceive e-cigarettes as appropriate gifts for smokers, especially heavy smokers. Precautions should be taken to prevent e-cigarettes from becoming a gift choice for nonsmokers. Health campaigns designed to combat the social acceptance of cigarette gifting may also help reduce e-cigarette gifting.

    Abstract We report a case of confirmed Mycoplasma pneumoniae infection in the setting of unilateral anterior uveitis and perineuritis without coexisting systemic manifestations. We hypothesize a causal association between acute M. pneumoniae infection and this patient's ocular presentation. Delay in identification of M. pneumoniae infection in this case prompted treatment with systemic and topical steroids for presumed autoimmune etiology. The rapid resolution of symptoms without concurrent antibiotic treatment suggests a possible postinfectious autoimmune component that may be responsive to steroid treatment.
