RESUMEN
Non-small cell lung cancers (NSCLCs) demonstrate intrinsic resistance to cell death, even after chemotherapy. Previous work suggested defective nuclear translocation of active caspase-3 in observed resistance to cell death. We have identified mitogen-activated protein kinase-activated protein kinase 2 (MK2; encoded by the gene MAPKAPK2) is required for caspase-3 nuclear translocation in the execution of apoptosis in endothelial cells. The objective was to determine MK2 expression in NSCLCs and the association between MK2 and clinical outcomes in patients with NSCLC. Clinical and MK2 mRNA data were extracted from two demographically distinct NSCLC clinical cohorts, North American (The Cancer Genome Atlas, TCGA) and East Asian (EA). Tumor responses following first round of chemotherapy were dichotomized as clinical response (complete response, partial response, and stable disease) or progression of disease. Multivariable survival analyses were performed using Cox proportional hazard ratios and Kaplan-Meier curves. NSCLC exhibited lower MK2 expression than SCLC cell lines. In patients, lower tumor MK2 transcript levels were observed in those presenting with late-stage NSCLC. Higher MK2 expression was associated with clinical response following initial chemotherapy and independently associated with improved 2-yr survival in two distinct cohorts, 0.52 (0.28-0.98) and 0.1 (0.01-0.81), TCGA and EA, respectively, even after adjusting for common oncogenic driver mutations. Survival benefit of higher MK2 expression was unique to lung adenocarcinoma when comparing across various cancers. This study implicates MK2 in apoptosis resistance in NSCLC and suggests prognostic value of MK2 transcript levels in patients with lung adenocarcinoma.

We have previously identified mitogen-activated protein kinase-activated protein kinase 2 (MK2) is required for caspase-3 nuclear translocation in the execution of apoptosis; however, little is known of the underlying mechanisms. Therefore, we sought to determine the role of kinase and nonkinase functions of MK2 in promoting nuclear translocation of caspase-3. We identified two non-small cell lung cancer cell lines for use in these experiments based on low MK2 expression. Wild-type, enzymatic and cellular localization mutant MK2 constructs were expressed using adenoviral infection. Cell death was evaluated by flow cytometry. In addition, cell lysates were harvested for protein analyses. Phosphorylation of caspase-3 was determined using two-dimensional gel electrophoresis followed by immunoblotting and in vitro kinase assay. Association between MK2 and caspase-3 was evaluated using proximity-based biotin ligation assays and co-immunoprecipitation. Overexpression of MK2 resulted in nuclear translocation of caspase-3 and caspase-3-mediated apoptosis. MK2 directly phosphorylates caspase-3; however, phosphorylation status of caspase-3 or MK2-dependent phosphorylation of caspase-3 did not alter caspase-3 activity. The enzymatic function of MK2 was dispensable in nuclear translocation of caspase-3. MK2 and caspase-3 associated together and a nonenzymatic function of MK2, chaperoned nuclear trafficking, is required for caspase-3-mediated apoptosis. Taken together, our results demonstrate a nonenzymatic role for MK2 in the nuclear translocation of caspase-3. Furthermore, MK2 may function as a molecular switch in regulating the transition between the cytosolic and nuclear functions of caspase-3.

PURPOSE: The aim of this study is to report two cases of paediatric Yolk sac tumours (YST) of the orbit and sinonasal tract, with a major review on the subject. METHODS: Two case reports along with a comprehensive retrospective literature review of all English language publications between 1974 and 2021 is presented. Literature review examined the demographics, clinical presentation and diagnostic and prognostic factors of extragonadal YSTs of the orbit and sinonasal tract. RESULTS: Orbit and sinuses are rare sites for YST, with only 25 paediatric cases reported in the literature. Extragonadal yolk sac tumours carry a significantly worse outcome than those localised to the gonads, with the 5-year survival of 66% and 81-89%, respectively. Our review found the median age of presentation to be 18 months (18 months for males and 24 months for females), and females are more commonly affected. The most common presentations were proptosis, facial swelling and ophthalmoplegia. Treatments and therefore outcomes varied in the cases due to the large time period. Of the cases reported in the last 10 years, all patients with data provided were alive and disease-free at follow-up. CONCLUSION: Sino-orbital yolk sac tumours are rare and have variable presentations, dependent on the extent of local invasion. Early diagnosis and treatment with multimodal therapy are paramount in having improved overall survival.

The COVID-19 pandemic has had widespread impact on healthcare, resulting in modifications to how we perform cancer research, including clinical trials for cancer. The impact of some healthcare workers and study coordinators working remotely and patients minimizing visits to medical facilities impacted clinical trial participation. Clinical trial accrual dropped at the onset of the pandemic, with improvement over time. Adjustments were made to some trial protocols, allowing telephone or video-enabled consent. Certain study activities were permitted to be performed by local healthcare providers or at local laboratories to maximize patients' ability to continue on study during these challenging times. We discuss the impact of COVID-19 on cancer clinical trials and changes at the local, cooperative group, and national level.

PURPOSE: To identify the molecular cause in five unrelated families with a distinct autosomal dominant ocular systemic disorder we called ROSAH syndrome due to clinical features of retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and migraine headache. METHODS: Independent discovery exome and genome sequencing in families 1, 2, and 3, and confirmation in families 4 and 5. Expression of wild-type messenger RNA and protein in human and mouse tissues and cell lines. Ciliary assays in fibroblasts from affected and unaffected family members. RESULTS: We found the heterozygous missense variant in the É-kinase gene, ALPK1, (c.710C>T, [p.Thr237Met]), segregated with disease in all five families. All patients shared the ROSAH phenotype with additional low-grade ocular inflammation, pancytopenia, recurrent infections, and mild renal impairment in some. ALPK1 was notably expressed in retina, retinal pigment epithelium, and optic nerve, with immunofluorescence indicating localization to the basal body of the connecting cilium of the photoreceptors, and presence in the sweat glands. Immunocytofluorescence revealed expression at the centrioles and spindle poles during metaphase, and at the base of the primary cilium. Affected family member fibroblasts demonstrated defective ciliogenesis. CONCLUSION: Heterozygosity for ALPK1, p.Thr237Met leads to ROSAH syndrome, an autosomal dominant ocular systemic disorder.

BACKGROUND: To evaluate the aetiology of paediatric optic atrophy in an Australian population. DESIGN: Retrospective review of medical records was conducted at The Children's Hospital at Westmead, Sydney, Australia. PARTICIPANTS: Two hundred twenty-seven subjects <16 years who were diagnosed with optic atrophy on fundoscopic examination between 1979 and 2015 were included in the study. METHODS: Subjects were obtained from the hospital database, which codes diagnoses for all admissions, as well as the orthoptic department database, which codes diagnoses for ophthalmology department outpatients. MAIN OUTCOME MEASURES: The predominant cause for optic atrophy was assigned to each patient. Clinical presentation was defined as the principal reason for evaluation. Demographic data included gender, affected eye and age at diagnosis. Data on medical comorbidities (cerebral palsy, developmental delay, microcephaly and seizures) and ocular comorbidities (strabismus and nystagmus) were collected. RESULTS: The mean age at initial eye review was 4.7 ± 4.4 years. There was bilateral optic atrophy in 81.5% of cases. Unilateral optic atrophy was largely due to tumours. When analysing over the three time periods, (1979-1990, 1991-2003 and 2004-2015), perinatal events (3.0%, 22.7% and 22.6%) and neurodegenerative disease (3.0%, 14.9% and 15.1%) are slowly replacing tumours (39.4%, 24.8% and 15.1%) as the top causes for paediatric optic atrophy. The incidence of other causes has remained fairly stable over time, albeit an increase in idiopathic causes. CONCLUSIONS: There has been shift in the etiological profile of optic atrophy. Whilst tumours are still an important cause of paediatric optic atrophy for an Australian population, perinatal events and neurodegenerative disease are becoming more significant.

OBJECTIVE: The present study examined (a) the presence of early maladaptive schemas and coping responses in children who have experienced maltreatment, (b) the relationship between early maladaptive schemas and coping responses, and (c) how qualitative findings compare to previous theoretical structures in quantitative studies. METHOD: There were 100 participants (Mage = 10.72 years, SD = 3.35; 64 girls, 30 boys, six transgender/nonbinary), with 70% identifying as White. Data were collected in collaboration with a community child advocacy center through forensic interviews in cases of reported child abuse. Early maladaptive schemas were assessed using an adapted version of the Dusseldorf Illustrated Schema Questionnaire for Children. Coping responses were assessed using the COPE Inventory. Information about individual and abuse factors was gathered from case reports. Child advocacy center staff completed the measures based on information obtained during forensic interviews. RESULTS: All assessed early maladaptive schemas were endorsed in this sample; children reported an ability to adapt through the use of socially supported and self-sufficient coping responses. Hierarchical cluster analysis examining word similarity within coded texts demonstrated that subjugation and self-sacrifice were most strongly related. CONCLUSION: This mixed-method study integrating children's voices contributes a new perspective on early maladaptive schemas and coping responses that can provide education to multidisciplinary teams involved in forensic interviews. However, limits to generalizability must be considered given that the sample was derived from one region in the U.S. Midwest. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
RESUMEN
Francisella tularensis is a Gram-negative facultative intracellular bacterial pathogen that is classified by the Centers for Disease Control and Prevention as a Tier 1 Select Agent. F. tularensis infection causes the disease tularemia, also known as rabbit fever. Treatment of tularemia is limited to few effective antibiotics which are associated with high relapse rates, toxicity, and potential emergence of antibiotic-resistant strains. Consequently, new therapeutic options for tularemia are needed. Through screening a focused chemical library and subsequent structure-activity relationship studies, we have discovered a new and potent inhibitor of intracellular growth of Francisella tularensis, D8-03. Importantly, D8-03 effectively reduces bacterial burden in mice infected with F. tularensis. Preliminary mechanistic investigations suggest that D8-03 works through a potentially novel host-dependent mechanism and serves as a promising lead compound for further development.

Autistic adults participate less and express lower satisfaction in leisure activities than nonautistic adults, although literature is limited. The multifaceted nature of leisure participation makes it challenging to measure, with most measures being retrospective. Ecological momentary assessments (EMA) can reduce recall bias. This pilot study assessed the feasibility and acceptability of EMA among autistic adults. Participants (N = 40) were recruited via email and online. After completing a baseline interview, participants were asked to complete a once-daily survey for 30 days, in which they received survey links through a text messaging smartphone app. Surveys asked participants to report whether they participated in any leisure activities during the day, their level of enjoyment, with whom they interacted, and where they participated. The EMA appeared feasible in this sample, as participants completed the daily survey on average 27.05 (SD = 3.92) days. Regarding acceptability, most agreed that survey timing was convenient, that it was easy to enter responses and answer questions daily, and that they had enough response time. Overall, this study supports the use of EMA methodology among autistic adults. Future research should follow and improve upon these EMA data collection practices to examine daily behavior and well-being among autistic adults.

BACKGROUND AND OBJECTIVES: Multiple reforms aimed at improving the Chinese population's health have been introduced in recent years, including several designed to improve access to innovative drugs. We sought to review current factors affecting access to innovative drugs in China and to anticipate future trends. METHODS: Targeted reviews of published literature and statistics on the Chinese healthcare system, medical insurance and reimbursement processes were conducted, as well as interviews with five Chinese experts involved in the reimbursement of innovative drugs. RESULTS: Drug reimbursement in China is becoming increasingly centralized due to the removal of provincial pathways, the establishment of the National Healthcare Security Administration and the implementation of the National Reimbursement Drug List (NRDL), which is now the main route for drug reimbursement in China. There is also an increasing number of other channels via which patients may access innovative treatments, including various types of commercial insurance and special access. Health technology assessment (HTA) and health economic evidence are becoming pivotal elements of the NRDL decision-making process. Alongside the optimization of HTA decision making, innovative risk-sharing agreements are anticipated to be increasingly leveraged in the future to optimize access to highly specialized technologies and encourage innovation while safeguarding limited healthcare funds. CONCLUSIONS: Drug public reimbursement in China continues to align more closely with approaches widely used in Europe in terms of HTA, health economics and pricing. Centralization of decision-making processes for public reimbursement of innovative drugs allows consistency in assessment and access, which optimizes the improvement of the Chinese population's health.
RESUMEN
OBJECTIVE: Childhood emotional abuse has been linked with mental and physical health concerns yet may be perceived as less severe than other forms of childhood abuse. The present study aims to (a) understand perceptions of childhood abuse forms across psychologists, general college-level students, and the general public and (b) investigate whether personal emotional abuse history affects perceptions of emotional abuse. METHOD: Participants (N = 444) completed the Childhood Trauma Questionnaire-Short Form and provided perceived abuse severity and offender responsibility on eight case vignettes of emotional, physical, sexual, and no abuse. Research Question 1 was tested with a two-way (Vignette Type × Participant Type) multivariate analysis of variance performed on perceived severity and offender responsibility scores. Research Question 2 included abuse history as a third factor to examine potential moderation. RESULTS: All three groups perceived scenarios regarding emotional abuse as less severe and the offender less responsible than scenarios regarding sexual or physical abuse. Unexpectedly, psychologists were just as variable in their perceptions of abuse severity across abuse forms, as compared to the general public and college students. However, psychologists with emotional abuse histories provided more severe ratings on emotional abuse items, more in line with general public perceptions. College students' and the general public's relative ratings were roughly equivalent regardless of emotional abuse history. CONCLUSIONS: The study calls for more attention to emotional abuse in psychologist training programs. Research and training to increase understanding of emotional abuse and its sequelae could move forward related educational outreach and legal proceedings.

RESUMEN
BACKGROUND: The Commission on Cancer implemented Standard 5.8 in 2021, which requires removal of 3 mediastinal nodes and 1 hilar node with lung cancer resection. We conducted a national survey to assess whether surgeons who treat lung cancer in different clinical settings correctly identify mediastinal lymph node stations. METHODS: Cardiac or thoracic surgeons expressing interest in lung cancer surgery on the Cardiothoracic Surgery Network were asked to complete a 7-question survey assessing their knowledge of lymph node anatomy. General surgeons whose practice includes thoracic surgery were invited through American College of Surgeon's Cancer Research Program. Results were analyzed using Pearson's chi-square test. Multivariable linear regression was used to identify predictors of a higher score on the survey. RESULTS: Of the 280 surgeons that responded, 86.8% were male and 13.2% were female; the median age was 50 years. Of these surgeons, 211 (75.4%) were thoracic, 59 (21.1%) were cardiac, and 10 (3.6%) were general surgeons. Surgeons were most likely to correctly identify lymph node stations 8R and 9R and least likely to correctly identify the midline pretracheal node just superior to the carina (4R). Surgeons whose practice involved a greater percentage of thoracic surgery patients and surgeons who performed a greater number of lobectomies scored higher on the lymph node assessment. CONCLUSION: Knowledge of mediastinal node anatomy among surgeons who perform thoracic surgery is generally high, but varies by clinical setting. Efforts are under way to better educate lung cancer surgeons on nodal anatomy, and to increase adoption of Standard 5.8.

Shiraz disease (SD) is an economically important virus-associated disease that can significantly reduce yield in sensitive grapevine varieties and has so far only been reported in South Africa and Australia. In this study, RT-PCR and metagenomic high-throughput sequencing was used to study the virome of symptomatic and asymptomatic grapevines within vineyards affected by SD and located in South Australia. Results showed that grapevine virus A (GVA) phylogroup II variants were strongly associated with SD symptoms in Shiraz grapevines that also had mixed infections of viruses including combinations of grapevine leafroll-associated virus 3 (GLRaV-3) and grapevine leafroll-associated virus 4 strains 5, 6 and 9 (GLRaV-4/5, GLRaV-4/6, GLRaV-4/9). GVA phylogroup III variants, on the other hand, were present in both symptomatic and asymptomatic grapevines, suggesting no or decreased virulence of these strains. Similarly, only GVA phylogroup I variants were found in heritage Shiraz grapevines affected by mild leafroll disease, along with GLRaV-1, suggesting this phylogroup may not be associated with SD.

BACKGROUND: A 2019 public workshop convened by the National Academies of Sciences, Engineering and Medicine (NASEM) Roundtable on Health Literacy identified a need to develop evidence-based guidance for best practices for health literacy and patient activation in clinical trials. PURPOSE: To identify studies of health literacy interventions within medical care or clinical trial settings that were associated with improved measures of health literacy or patient activation, to help inform best practices in the clinical trial process. DATA SOURCES: Literature searches were conducted in PubMed, the Cumulative Index to Nursing and Allied Health Literature, SCOPUS, Cochrane, and Web of Science from January 2009 to June 2021. STUDY SELECTION: Of 3592 records screened, 22 records investigating 27 unique health literacy interventions in randomized controlled studies were included for qualitative synthesis. DATA EXTRACTION: Data screening and abstraction were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. DATA SYNTHESIS: Types of health literacy interventions were multimedia or technology-based (11 studies), simplification of written material (six studies) and in-person sessions (five studies). These interventions were applied at various stages in the healthcare and clinical trial process. All studies used unique outcome measures, including patient comprehension, quality of informed consent, and patient activation and engagement. CONCLUSIONS: The findings of our study suggest that best practice guidelines recommend health literacy interventions during the clinical trial process, presentation of information in multiple forms, involvement of patients in information optimization, and improved standardization in health literacy outcome measures.
