ABSTRACT
The Sc2.0 project is building a eukaryotic synthetic genome from scratch. A major milestone has been achieved with all individual Sc2.0 chromosomes assembled. Here, we describe the consolidation of multiple synthetic chromosomes using advanced endoreduplication intercrossing with tRNA expression cassettes to generate a strain with 6.5 synthetic chromosomes. The 3D chromosome organization and transcript isoform profiles were evaluated using Hi-C and long-read direct RNA sequencing. We developed CRISPR Directed Biallelic URA3-assisted Genome Scan, or "CRISPR D-BUGS," to map phenotypic variants caused by specific designer modifications, known as "bugs." We first fine-mapped a bug in synthetic chromosome II (synII) and then discovered a combinatorial interaction associated with synIII and synX, revealing an unexpected genetic interaction that links transcriptional regulation, inositol metabolism, and tRNASerCGA abundance. Finally, to expedite consolidation, we employed chromosome substitution to incorporate the largest chromosome (synIV), thereby consolidating >50% of the Sc2.0 genome in one strain.

BACKGROUND: Exposures associated with mpox infection remain imperfectly understood. METHODS: We conducted a case-control study enrolling participants who received molecular tests for mpox/orthopoxvirus in California from November 2022 through June 2023. We collected data on behaviors during a 21-day risk period before symptom onset or testing among mpox case patients and test-negative controls. RESULTS: Thirteen of 54 case patients (24.1%) and 5 of 117 controls (4.3%) reported sexual exposure to individuals they identified as potential mpox case patients ("index contacts"; odds ratio [OR], 7.7 [95% confidence interval (CI), 2.5-19.3] relative to individuals who did not report exposure to potential mpox case patients). Among these participants, 10 of 13 case patients (76.9%) and 2 of 5 controls (40.0%) reported that their index contacts were not experiencing symptoms visible to participants during sex (OR, 14.9 [95% CI, 3.6-101.8]). Only 3 of 54 case patients (5.6%) reported exposure to symptomatic index contacts. Case patients reported more anal/vaginal sex partners than did controls (adjusted OR, 2.2 [95% CI, 1.0-4.8] for 2-3 partners and 3.8 [1.7-8.8] for ≥4 partners). Male case patients with penile lesions more commonly reported insertive anal/vaginal sex than those without penile lesions (adjusted OR, 9.3 [95% CI, 1.6-54.8]). Case patients with anorectal lesions more commonly reported receptive anal sex than those without anorectal lesions (adjusted OR, 14.4 [95% CI, 1.0-207.3]). CONCLUSIONS: Sexual exposure to contacts known or suspected to have experienced mpox was associated with increased risk of infection, often when index contacts lacked apparent symptoms. Exposure to more sex partners, including those whom participants did not identify as index contacts, was associated with increased risk of infection in a site-specific manner. While participants' assessment of symptoms in partners may be imperfect, these findings suggest that individuals without visibly prominent mpox symptoms transmit infection.

OBJECTIVE: The present study aimed to understand the role of critical action, sociopolitical participation, an essential form of consciousness in the relationship between interpersonal discrimination and the use of tobacco products. METHOD: The present study was part of a more extensive longitudinal study on students' genetic and environmental experiences. To examine these associations, 164 racially minoritized college students (Mage = 19.86, SD = 0.28) were surveyed for this study. RESULTS: Findings indicated that the relation between interpersonal ethnic-racial discrimination (IERD) and tobacco products was moderated by critical action. Specifically, IERD was associated with greater use of tobacco products when students had low critical consciousness-critical action. The relation between IERD and the use of tobacco products became nonsignificant when students had high critical action. CONCLUSIONS: Critical action was protective in mitigating increased tobacco use in the context of discrimination experiences. Research, clinical, and policy implications are discussed in efforts to reduce tobacco-related disparities among racially minoritized college students.

ABSTRACT
BACKGROUND: California has experienced an increase in reported cases of disseminated gonococcal infection (DGI). Given significant morbidity associated with DGI and the ability of Neisseria gonorrhoeae to rapidly develop antibiotic resistance, characterization of these cases can inform diagnosis, management, and prevention of DGI. METHODS: As part of the public health response to increased reports of DGI, we used gonorrhea surveillance data reported to the California Department of Public Health to identify all DGI cases in a geographically-bound region. Standardized case report forms were used to collect epidemiologic risk factors and clinical information obtained from provider/laboratory reports, medical records, and patient interviews. RESULTS: From 1 July 2020 to 31 July 2021, we identified 149 DGI patients among 63 338 total gonorrhea infections, representing 0.24% of gonorrhea cases. Estimated incidence was 0.47 DGI cases per 100 000 person-years. Mean age of DGI patients was 40 years, and 75 (50%) were cisgender men, of whom only 13 were known to have male partners. Where reported, more than one-third (36%) used methamphetamine and nearly one-quarter (23%) experienced homelessness. Clinically, 61% lacked urogenital, pharyngeal, or rectal symptoms; 2 patients died in the hospital. Among 47 isolates from patients with antimicrobial susceptibility testing (AST) results available, all were susceptible to ceftriaxone and cefixime. CONCLUSIONS: Most DGI patients lacked urogenital symptoms and were not among populations for which routine gonorrhea screening is currently recommended. Expanding gonorrhea screening might prevent DGI. Cefixime is likely the best option if transitioning from parenteral to oral therapy when AST results are unavailable.

Pathogenic variants in TRAF7 are often de novo and features of individuals harboring these variants are characterized by neurodevelopmental delay, ptosis, cardiac defects, limb anomalies, and dysmorphic features. We present a familial case in two African American patients with a novel, likely pathogenic c.1936G>A variant in TRAF7. Patient 1 is a 31-year-old female with a patent ductus arteriosus (PDA), intellectual disability, ptosis, and other dysmorphic features. She was identified to harbor this likely pathogenic variant in a mosaic (33.89%) state in leukocytes. Her son, Patient 2, is a 10-month-old male with a PDA, atrial septal defect, ptosis, developmental delay, history of feeding difficulties, congenital maxillary frenulum, and malrotation of the intestine. He has the same variant in a non-mosaic state. These cases demonstrate the variable expressivity observed with variants in TRAF7 within the same family and expand upon current understanding of mosaic TRAF7 variants. They also provide phenotypic data on genetic variation in individuals with African American ancestry, a population who has been underrepresented in the literature and may be less frequently referred to genetic specialists.

The objective of this study was to identify interpretation challenges specific to exome sequencing and errors of potential clinical significance in the context of genetic counseling for adults at risk for a hereditary cancer syndrome. Thirty transcripts of interpreter-mediated telephone results disclosure genetic counseling appointments were coded for errors by bilingual researchers, and the coders applied an overall rating to denote the degree to which the errors interfered with communication overall. Genetic counselors reviewed a subset of errors flagged for potential clinical significance to identify those likely to have clinical impact. Qualitative interviews with 19 interpreters were analyzed to elucidate the challenges they face in interpreting for genetic counseling appointments. Our analysis identified common interpretation errors such as raising the register, omissions, and additions. Further, we found errors specific to genetic counseling concepts and content that appeared to impact the ability of the genetic counselor to accurately assess risk. These errors also may have impacted the patient's ability to understand their results, access appropriate follow-up care, and communicate with family members. Among interpreters' strengths was the use of requests for clarification; in fact, even more use of clarification would have been beneficial in these encounters. Qualitative interviews surfaced challenges stemming from the structure of interpreter work, such as switching from medical and nonmedical interpretations without substantial breaks. Importantly, while errors were frequent, most did not impede communication overall, and most were not likely to impact clinical care. Nevertheless, potentially clinically impactful errors in communication of genetics concepts may contribute to inequitable care for limited English proficient patients and suggest that additional training in genetics and specialization in healthcare may be warranted. In addition, training for genetic counselors and guidance for patients in working effectively with interpreters could enhance interpreters' transmission of complex genetic concepts.

Anti-Black racism (ABR) contributes to racial trauma and to the disproportionate negative mental, physical, and social outcomes faced by Black populations (Hargons et al., 2017; Wun, 2016a). The previous literature demonstrates that storytelling and other narrative interventions are often used to promote collective healing among Black people (Banks-Wallace, 2002; Moors, 2019). Storying survival (i.e., the utilization of stories to promote liberation from racial trauma) is one such narrative intervention (Mosley et al., 2021); however, little is known about the processes by which Black people utilize storying survival to promote radical healing. Using an intersectional framework and thematic analysis from a phenomenological perspective (Braun & Clarke, 2006), the present study analyzed interviews from 12 racial justice activists in order to understand how these activists engage in storying survival to foster Black survival and healing. Results show that storying survival includes five interconnected components: storying influences, mechanisms of storying survival, content of storying survival, context of storying survival, and impact of storying survival. Each of these categories and subcategories are detailed herein and are supported with quotations. The findings and related discussion explore the concept of storying survival and its contributions to critical consciousness, radical hope, strength and resistance, cultural self-knowledge, and collectivism among participants and their communities. This study therefore provides important and practical information about how Black people and the counseling psychologists who aim to serve them can utilize storying survival to resist and heal from ABR.

OBJECTIVES: Due to the exponential growth in the Latinx older adult population, culturally responsive services are needed, especially since most healthcare providers are non-Latinx with limited Spanish or bilingual skills. One place to start is by drawing a formative assessment of the healthcare providers' knowledge and awareness of the healthcare needs of Latinx older adults. METHODS: Focus groups were conducted to explore the healthcare providers' knowledge and awareness of cultural and structural barriers and facilitators to accessing health care services for Latinx older adults. RESULTS: Results note that healthcare providers perceived the healthcare needs for Latinx older adults to be underutilized for healthcare services, preventive interventions for healthy diet/lifestyle, and healthcare knowledge. Providers reported Latinx family over-involvement, religiosity, immigration, and language/lack of interpreters as barriers to seeking timely healthcare. Finally, healthcare providers said that family support, the location of healthcare services, and community-based partnerships were all facilitators for seeking healthcare. CONCLUSIONS: Findings suggest providers' conflicting perspectives toward the Latinx communities. CLINICAL IMPLICATIONS: Healthcare services can consider implementing trainings for non-Latinx providers to recognize conflicting perspectives and reduce implicit bias toward the Latinx communities.

The mechanisms that regulate the physical properties of the cell interior remain poorly understood, especially at the mesoscale (10nm-100nm). Changes in these properties have been suggested to be crucial for both normal physiology and disease. Many crucial macromolecules and molecular assemblies such as ribosomes, RNA polymerase, and biomolecular condensates span the mesoscale size range. Therefore, we need better tools to study the cellular environment at this scale. A recent approach has been to use genetically encoded multimeric nanoparticles (GEMs), which consist of self-assembling scaffold proteins fused to fluorescent tags. After translation of the fusion protein, the monomers self-assemble into bright and stable nanoparticles of defined geometry that can be visualized by fluorescence microscopy. Physical properties of the cell can then be inferred through analysis of the motion of these particles, an approach called nanorheology. Previously, 40nm-GEMs elucidated TORC1 kinase as a regulator of cytoplasmic crowding. However, extremely sensitive microscopes were required. Here, we describe the development and characterization of a 50 nm diameter GEM that is brighter and probes a larger length scale. 50nm-GEMs will make high-throughput nanorheology accessible to a broader range of researchers and reveal new insights into the biophysical properties of cells.
ABSTRACT
INTRODUCTION: This study investigated the efficacy and safety of neoadjuvant chemotherapy for locally advance penile squamous cell carcinoma for which current evidence is lacking. METHODS: Included patients had locally advanced penile squamous cell carcinoma with clinical lymph node metastasis treated with at least 1 dose of neoadjuvant chemotherapy prior to planned consolidative lymphadenectomy. Objective response rates were assessed using Response Evaluation Criteria in Solid Tumors v1.1. The primary and secondary outcomes were overall survival and progression-free survival, estimated by the Kaplan-Meier method. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events v5.0. RESULTS: A total of 209 patients received neoadjuvant chemotherapy for locally advanced and clinically node-positive penile squamous cell carcinoma. The study population consisted of 7% of patients with stage II disease, 48% with stage III, and 45% with stage IV. Grade 2 treatment-related adverse events occurred in 35 (17%) patients, and no treatment-related mortality was observed. Of the patients, 201 (97%) completed planned consolidative lymphadenectomy. During follow-up, 106 (52.7%) patients expired, with a median overall survival of 37.0 months (95% confidence interval [CI] = 23.8 to 50.1 months) and median progression-free survival of 26.0 months (95% CI = 11.7 to 40.2 months). Objective response rate was 57.2%, with 87 (43.2%) having partial response and 28 (13.9%) having a complete response. Patients with objective response to neoadjuvant chemotherapy had a longer median overall survival (73.0 vs 17.0 months, P < .01) compared with those who did not. The lymph node pathologic complete response rate was 24.8% in the cohort. CONCLUSION: Neoadjuvant chemotherapy with lymphadenectomy for locally advanced penile squamous cell carcinoma is well tolerated and active to reduce the disease burden and improve long-term survival outcomes.

This study investigates how mediating (e.g. history of health conditions) and moderating (e.g. self-rated health) factors are associated with nativity status on depression and anxiety in Mexican immigrants. Using data from the 2019 National Health Interview Survey (NHIS), results found a significant direct association between nativity status and anxiety and depression. Additionally, the association between nativity status and mental health was mediated by the history of health conditions, and self-rated health was a significant moderator in both mediation models. Study findings are discussed within the context of barriers to care, current literature, and strengths-based interventions. Future research can expand upon these findings by examining the specific types of physical and mental health conditions that may support the Hispanic Paradox, as well as how self-efficacy and internal locus of control are associated with the paradox within this population.
ABSTRACT
Background: Group Motivational Interviewing for Teens (GMIT) has been effective in reducing youth substance use in diverse communities, yet more research is needed to determine its efficacy in reducing tobacco and alternative tobacco products (ATP) use among Latine adolescents. This study modified GMIT to include a focus on ATPs (GMIT-ATP). GMIT was also linguistically translated so it could be offered in English and Spanish, culturally enhanced, and parent sessions were added (GMIT-ATP + P). Methods: The study's aims were to 1) Develop a model of how cultural context, family relationships, and adolescent tobacco-related skills/beliefs are associated with smoking and ATP use; 2) Examine the impact of the GMIT-ATP intervention on adolescent tobacco use; 3) Examine whether the GMIT-ATP + P intervention improves family/parenting factors associated with reduced adolescent tobacco use; 4) Examine whether GMIT-ATP + P is more effective than GMIT-ATP in improving adolescent tobacco use; 5) Explore whether essential components of our behavior change model mediate the impact on tobacco use, and 6) Explore whether cultural factors influence the impacts of our intervention. Latine adolescents (ages 10-16) and their parents/guardians were recruited throughout Virginia. Parents and adolescents completed three surveys: before and immediately after the program ends and at 3-months post-intervention. Families attended 3 GMIT-ATP or GMIT-ATP + P sessions. Conclusion: Findings from this study will be disseminated in Latine communities and with providers working with Latine youth and can serve as a community-based model to reduce substance and tobacco use (e.g., ATP) in these Latine communities.
ABSTRACT
Background: Older adults are at a greater risk for contracting and experiencing severe illness from COVID-19 and may be further affected by pandemic-related precautions (e.g., social distancing and isolation in quarantine). However, the longitudinal impact of the COVID-19 pandemic on older adults is unclear. The current study examines changes in health behaviors, psychosocial factors, and cognitive functioning in a large sample of older adults using a pre-pandemic baseline and longitudinal follow-up throughout 9 months of the COVID-19 pandemic. Methods: One hundred and eighty-nine older adults (ages 65-89) were recruited from a multisite clinical trial to complete additional virtual assessments during the COVID-19 pandemic. Mixed effects models evaluated changes in health behaviors, psychosocial factors, and cognitive functioning during the pandemic compared to a pre-pandemic baseline and over the course of the pandemic (i.e., comparing the first and last COVID-19 timepoints). Results: Compared to their pre-pandemic baseline, during the pandemic, older adults reported worsened sleep quality, perceived physical health and functioning, mental health, slight increases in depression and apathy symptoms, reduced social engagement/perceived social support, but demonstrated better performance on objective cognitive tasks of attention and working memory. Throughout the course of the pandemic, these older adults reported continued worsening of perceived physical health and function, fewer depression symptoms, and they demonstrated improved cognitive performance. It is important to note that changes on self-report mood measures and cognitive performance were relatively small regarding clinical significance. Education largely served as a protective factor, such that greater years of education was generally associated with better outcomes across domains. Conclusions: The present study provides insights into the longitudinal impact of the COVID-19 pandemic on health behaviors, psychosocial factors, and cognitive functioning in a population disproportionately affected by the virus. Replicating this study design in a demographically representative older adult sample is warranted to further inform intervention strategies targeting older adults negatively impacted by the COVID-19 pandemic.
ABSTRACT
Objectives: Most acute stroke research is conducted at academic and larger hospitals, which may differ from many non-academic (ie, community) and smaller hospitals with respect to resources and consultant availability. We describe current emergency department (ED) and hospital-level stroke-related capabilities among a sample of community EDs participating in the Emergency Quality Network (E-QUAL) stroke collaborative. Methods: Among E-QUAL-participating EDs, we conducted a survey to collect data on ED and hospital stroke-related structural and process capabilities associated with quality of stroke care delivery and patient outcomes. EDs submitted data using a web-based submission portal. We present descriptive statistics of self-reported capabilities. Results: Of 154 participating EDs in 30 states, 97 (63%) completed the survey. Many were rural (33%); most (82%) were not certified stroke centers. Although most reported having stroke protocols (67%), many did not include hemorrhagic stroke or transient ischemic attack (45% and 57%, respectively). Capability to perform emergent head computed tomography and to administer thrombolysis were not universal (absent in 4% and 5%, respectively). Access to neurologic consultants varied; 18% reported no 24/7 availability onsite or remotely. Of those with access, 48% reported access through telemedicine only. Admission capabilities also varied with patient transfer commonly performed (79%). Conclusion: Stroke-related capabilities vary substantially between community EDs and are different from capabilities typically found in larger stroke centers. These data may be valuable for identifying areas for future investment. Additionally, the design of stroke quality improvement interventions and metrics to evaluate emergency stroke care delivery should account for these key structural differences.
ABSTRACT
BACKGROUND: Working memory decline has been associated with normal aging. The frontal brain structure responsible for this decline is primarily located in the prefrontal cortex (PFC). Our previous neuroimaging study demonstrated a significant change in functional connectivity between the left dorsolateral PFC (DLPFC) and left ventrolateral PFC (VLPFC) when applying 2 mA tDCS in MRI scanner during an N-Back task. These regions were part of the working memory network. The present study is the first study that utilizes individualized finite element models derived from older adults' MRI to predict significant changes of functional connectivity observed from an acute tDCS application. METHODS: Individualized head models from 15 healthy older adults (mean age = 71.3 years) were constructed to create current density maps. Each head model was segmented into 11 tissue types: white matter, gray matter, CSF, muscle, blood vessels, fat, eyes, air, skin, cancellous, and cortical bone. Electrodes were segmented from T1-weighted images and added to the models. Computed median and maximum current density values in the left DLPFC and left VLPFC regions of interest (ROIs) were correlated with beta values as functional connectivity metrics measured in different timepoint (baseline, during stimulation) and stimulation condition (active and sham). MAIN RESULTS: Positive significant correlations (R2 = 0.523 for max J, R2 = 0.367 for median J, p < 0.05) were found between the beta values and computed current densities in the left DLPFC ROIs for active stimulation, but no significant correlation was found during sham stimulation. We found no significant correlation between connectivity and current densities computed in the left VLPFC for both active and sham stimulation. CONCLUSIONS: The amount of current within the left DLPFC ROIs was found positively correlated with changes in functional connectivity between left DLPFC and left VLPFC during active 2 mA stimulation. Future work may include expansion of number of participants to further test the accuracy of tDCS models used to predict tDCS-induced functional connectivity changes within the working memory network.

Desde el 2008 Colombia aprueba la Política Nacional de Seguridad Alimentaria y Nutricional, esta recomienda la lactancia materna (LM) por los beneficios en el bienestar de la familia y el niño, al prevenir infecciones respiratorias, digestivas, neurológicas y por sus características nutricionales que contribuyen a un adecuado desarrollo neurológico, ganancia de talla y peso, este estudio evaluó esta práctica en población rural. Métodos Mediante grupos focales, 25 personas convocadas por escuelas campesinas de agroecología intercambiaron prácticas y saberes sobre LM, las entrevistadas corresponden a la generación actual y la anterior que tuvieron experiencias de LM. Resultados La generación más joven con paridad entre 1 y 5, lactó en promedio 14.9 meses y las abuelas con paridad entre 1 y 12, lactó en promedio 22 meses. La leche entera de vaca se aprecia tanto como la leche humana, esta es valorada por sus efectos en el desarrollo y bienestar de los hijos, siendo más alegres y activos, más no reconocen sus beneficios económicos. Consideran que genera alteraciones físicas en las madres y en la sexualidad de los varoncitos. Conclusiones Disminuyó en 7 meses el promedio de duración de la LM entre las dos generaciones de madres. El desarrollo motor precoz y las expresiones de sexualidad observadas en los hijos, durante el acto de amamantamiento, motivaron a algunas madres a suspenderla antes de los 2 años de edad, igualmente los cambios anatómicos que afectan sicológica y estéticamente a las madres. Los participantes no valoran económica ni socialmente la LM.
Since 2008, Colombia has approved the National Food and Nutrition Security Policy, which recommends breastfeeding for welfare benefits of the family and child, and preventing respiratory, digestive, neurological infections and their contributing nutritional characteristics-Methods Through focus groups, 25 people convened by schools of agroecology exchanged practices and knowledge about breastfeeding, the interviewees correspond to the current and previous generations who practiced breastfeeding. Results The youngest generation with parity between 1 and 5, had breastfeeding mean 14.9 months and grandmothers had parity between 1 and 12, lactated on average 22 months. All them were thinking Whole cow’s milk is good as human milk. Breastfeeding was valued for its effects on the development and well-being of children, their children being more cheerful and active, but they do not recognize their economic benefits in breastfeeding vs cow’s milk. The mothers consider that breastfeeding generates physical alterations in the mothers and in the sexuality of the children Conclusions Breastfeeding decreased in seven months between the two generations. The early motor development and the expressions of sexuality observed in the children, during breastfeeding, motivated some mothers to suspend before the 2 years of age, also the anatomical changes perceiving for mothers was defined cause for interrupt breastfeeding .
