RESUMO
INTRODUCTION: Since its inception in 2003, the Project Extension for Community Healthcare Outcomes (ECHO) tele-education model has reached and improved outcomes for patients, providers, and health centers through interventions in >180 countries. Utilization of this model has recently increased due to the COVID-19 pandemic and a higher demand for remote education. However, limited research has examined the methodologies used to evaluate Project ECHO interventions. METHODS: We conducted a scoping review to determine the extent and types of research methods used to evaluate outcomes and implementation success of Project ECHO interventions and to identify gaps and opportunities for future investigation. Using Arksey and O'Malley's scoping review framework and the PRISMA-ScR checklist, we reviewed study designs, temporality, analysis methods, data sources, and levels and types of data in 121 articles evaluating Project ECHO interventions. RESULTS: Most interventions addressed substance use disorders (24.8%, n = 30), infectious diseases (24%, n = 29), psychiatric and behavioral health conditions (21.5%, n = 26), and chronic diseases (19%, n = 23). The most frequently reported evaluation methods included cohort studies (86.8%, n = 105), longitudinal designs (74.4%, n = 90), mixed methods analysis (52.1%, n = 63), surveys (61.2%, n = 74), process evaluation measures (98.3%, n = 119), and provider-level outcome measures (84.3%, n = 102). Few evaluations used experimental designs (1.7%, n = 2), randomization (5.8%, n = 7), or comparison groups (14%, n = 17), indicating limited rigor. DISCUSSION: This scoping review demonstrates the need for more rigorous evaluation methods to test the effectiveness of the Project ECHO model at improving outcomes and standardized reporting guidelines to enhance the dissemination of evaluation data from future Project ECHO interventions.
RESUMO
OBJECTIVES: To compare 12-month spinal fusion surgery rates in the setting of low back pain among digital musculoskeletal (MSK) program participants versus a comparison cohort who only received usual care. STUDY DESIGN: Retrospective cohort study with propensity score matched comparison cohort using commercial medical claims data representing over 100 million commercially insured lives. METHODS: All study subjects experienced low back pain between January 2020 and December 2021. Digital MSK participants enrolled in the digital MSK low back program between January 2020 and December 2021. Non-participants had low back pain related physical therapy (PT) between January 2020 and December 2021. Digital MSK participants were matched to non-participants with similar demographics, comorbidities and baseline MSK-related medical care use. Spinal fusion surgery rates at 12 months post participation were compared. RESULTS: Compared to non-participants, digital MSK participants had lower rates of spinal fusion surgery in the post-period (0.7% versus 1.6%; p < 0.001). Additionally, in the augmented inverse probability weighting (AIPW) model, digital MSK participants were found to have decreased odds of undergoing spinal fusion surgery (adjusted odds ratio: 0.64, 95% CI: 0.51-0.81). CONCLUSIONS: This study provides evidence that participation in a digital MSK program is associated with a lower rate of spinal fusion surgery.

We synthesized stereoselectively four stereoisomers of oxylipins (1a-d) by a convergent approach based on chiral catalysis. The synthetic approach involved sequential assembly of two key fragments - ene-diol and allyl alcohol - for an intended convergent cross-metathesis reaction to join these fragments. The key steps include Sharpless kinetic resolution, asymmetric dihydroxylation and Grubbs cross-metathesis. The characterization of the synthesized oxylipins revealed spectroscopic data that were consistent with previously reported values.
RESUMO
Bacterial degradation of natural rubber (NR) in an oxic environment is initiated by oxidative cleavage of double bonds in the NR-carbon backbone and is catalyzed by extracellular haem-containing rubber oxygenases. NR-cleavage products of sufficiently low molecular mass are taken up by the cells and metabolized for energy and biomass formation. Gram-negative and Gram-positive NR-degrading bacteria (usually) employ different types of rubber oxygenases such as RoxA and/or RoxB (most Gram-negative NR-degraders) or latex clearing protein Lcp (most Gram-positive NR-degraders). In order to find novel orthologues of Rox proteins, we have revisited databases and provide an update of Rox-like proteins. We describe the putative evolution of rubber oxygenases and confirm the presence of a third subgroup of Rox-related proteins (RoxCs), the biological function of which remains, however, unclear. We summarize the knowledge on the taxonomic position of Steroidobacter cummioxidans 35Y and related species. Comparison of genomic and biochemical features of strain 35Y with other species of the genus Steroidobacter suggests that strain 35Y represents a species of a novel genus for which the designation Aurantibaculum gen. nov. is proposed. A short summary on the capabilities of NR-degrading consortia, that could be superior in biotechnological applications compared to pure cultures, is also provided. KEY POINTS: ⢠Three types of rubber oxygenases exist predominantly in Gram-negative microbes ⢠S. cummioxidans 35Y contains RoxA and RoxB which are superior in activity ⢠S. cummioxidans 35Y represents a species of a novel genus.

BACKGROUND: Genetic testing can help determine the risk of many cancers and guide cancer prevention and treatment plans. Despite increasing concern about disparities in precision cancer medicine, public knowledge and cancer genetic testing by race and ethnicity have not been well investigated. METHODS: We analyzed data from the 2020 Health Information National Trends Survey in 2022. Self-reported cancer genetic testing (e.g., Lynch syndrome, BRCA1/2) knowledge and utilization were compared by race and ethnicity. Perceived importance of genetic information for cancer care (prevention, detection, and treatment) was also examined in relation to the uptake of cancer genetic testing. Multivariable logistic regression models were employed to examine factors associated with knowledge and genetic testing to calculate predicted probability of undergoing genetic testing by race and ethnicity. RESULTS: Of 3551 study participants, 37.8% reported having heard of genetic testing for cancer risk and 3.9% stated that they underwent cancer genetic testing. Being non-Hispanic Black (OR=0.47, 95% CI=0.30-0.75) or Hispanic (OR=0.56, CI=0.35-0.90) was associated with lower odds of genetic testing knowledge. Although Hispanic or non-Hispanic Black respondents were more likely to perceive higher importance of genetic information versus non-Hispanic Whites, they had a lower predicted probability of cancer genetic testing. CONCLUSION: Non-Hispanic Black and Hispanic adults had lower knowledge and were less likely to undergo cancer genetic testing than non-Hispanic Whites. Further research is needed on sources of genetic testing information for racial and ethnic minorities and the barriers to accessing genetic testing to inform the development of effective cancer risk genetic testing promotion.

Background: Research focused on disparities related to mental health comorbidities, especially among emerging adults with diabetes, is limited. Identifying associated factors of disparities could inform policy decisions to make diabetes-related interdisciplinary care more accessible for vulnerable groups. Method: Using data from the National Survey on Drug Use and Health (2015-2019), we examined disparities in presence of major depressive episode (MDE) and suicidal ideation among emerging adults with diabetes. Survey design-adjusted bivariate and multivariable logistic regression models were used for statistical analyses. Results: The study included 1,125 emerging adults (18-25 years old), with a history of type 1 diabetes (T1D) or type 2 diabetes (T2D). After controlling for sociodemographic and health-related characteristics, we found lower odds of having past-year major MDE for non-Hispanic Black (AOR, 0.42, p=0.032) compared to their non-Hispanic White counterparts. Females were 3.02 times more likely to have past-year MDE than males (AOR, 3.02, p=0.004). The odds of having past-year MDE were 1.96 times higher among individuals who identified as LGB (lesbian, gay, bisexual) (AOR, 1.96, P=0.038). There were no statistically significant disparities in suicidal ideation related to race/ethnicity, sex, education, and family income. However, individuals who identified as LGB had significantly higher likelihood of suicidal ideation than their heterosexual counterparts (AOR, 2.47, P=0.004). Conclusion: Significant disparities related to MDE and suicidal ideation exist based on race/ethnicity, gender, and sexual orientation. Integration of a mental health professional into the multidisciplinary diabetes care team is critical for effective management of comorbid mental health conditions in younger patients with diabetes.

OBJECTIVES: Palliative care can improve the quality of life of adolescents and young adults (AYA) with cancer. However, little is known about the utilization of palliative care among AYA cancer patients. Identifying factors associated with the utilization of palliative care could inform efforts to improve palliative care access among AYA patients living with cancer. METHODS: Using data from the National Inpatient Sample 2016-2019, a representative sample of US hospitalizations, we examined palliative care encounters and associated characteristics among hospitalizations of AYA with cancer and high inpatient mortality risk. Survey design-adjusted bivariate and multivariable logistic regression models were used to examine associations of patient- and hospital-level characteristics with palliative care. RESULTS: Of 10,979 hospitalizations by AYA cancer patients with high mortality risk, 19.9% received palliative care services between 2016 and 2019. After adjusting for all characteristics, independent predictors of palliative care use were as follows: older age (25-39 years old vs. 25-39 years; odds ratio [OR] 1.31, 95% confidence interval [CI] 1.15-1.49), Hispanic/Latinx (vs. non-Hispanic White; OR 1.16, 95% CI 1.01-1.34), female (vs. male; OR 1.27, 95% CI 1.14-1.41), public insurance (vs. private insurance; OR 1.23, 95% CI 1.10-1.38), hospital location in the US South (vs. Northeast; OR 0.78, 95% CI 0.66-0.94), and a large hospital (vs. small; OR 0.83, 95% CI 0.72-0.96). SIGNIFICANCE OF RESULTS: Less than 20% of AYAs with cancer and high risk of mortality received inpatient palliative care services. Further research is needed to explore the reasons for lower palliative care utilization in the younger age groups.
RESUMO
Glioblastoma is one of the most difficult tumor types to manage, having high morbidity and mortality with available therapies (surgery, radiotherapy and chemotherapy). Immunotherapeutic agents like Oncolytic Viruses (OVs), Immune Checkpoint Inhibitors (ICIs), Chimeric Antigen Receptor (CAR) T cells and Natural Killer (NK) cell therapies are now being extensively used as experimental therapies in the management of glioblastoma. Oncolytic virotherapy is an emerging form of anti-cancer therapy, employing nature's own agents to target and destroy glioma cells. Several oncolytic viruses have demonstrated the ability to infect and lyse glioma cells by inducing apoptosis or triggering an anti-tumor immune response. In this mini-review, we discuss the role of OV therapy (OVT) in malignant gliomas with a special focus on ongoing and completed clinical trials and the ensuing challenges and perspectives thereof in subsequent sections.

Nanotechnology-based drug delivery platforms have shown great potential in overcoming the limitations of conventional therapy for glioblastoma (GBM). However, permeation across the blood-brain barrier (BBB), physiological complexity of the brain, and glioma targeting strategies cannot entirely meet the challenging requirements of distinctive therapeutic delivery stages. The objective of this research is to fabricate lipid nanoparticles (LNPs) for the co-delivery of paclitaxel (PTX) and miltefosine (HePc) a proapoptotic agent decorated with transferrin (Tf-PTX-LNPs) and investigate its anti-glioma activity both in vitro and in vivo orthotopic NOD/SCID GBM mouse model. The present study demonstrates the anti-glioma effect of the dual drug combination of PTX and proapoptotic HePc lipid-based transferrin receptor (TfR) targeted alternative delivery (direct nose to brain transportation) of the nanoparticulate system (Tf-PTX-LNPs, 364 ± 5 nm, -43 ± 9 mV) to overcome the O6-methylguanine-DNA methyltransferase induce drug-resistant for improving the effectiveness of GBM therapy. The resulting nasally targeted LNPs present good biocompatibility, stability, high BBB transcytosis through selective TfR-mediated uptake by tumor cells, and effective tumor penetration in the brain of GBM induced mice. We observed markedly enhanced anti-proliferative efficacy of the targeted LNPs in U87MG cells compared to free drug. Nasal targeted LNPs had shown significantly improved brain concentration (Cmax fivefold and AUC0-24 4.9 fold) with early tmax (0.5 h) than the free drug. In vivo intracranial GBM-bearing targeted LNPs treated mice exhibited significantly prolonged survival with improved anti-tumor efficacy accompanied by reduced toxicity compared to systemic Taxol® and nasal free drug. These findings indicate that the nasal delivery of targeted synergistic nanocarrier holds great promise as a non-invasive adjuvant chemotherapy therapy of GBM.

OBJECTIVE: People with disability (PWD) often experience chronic pain, and opioid is widely used prescription medication. However, population-based evidence of opioid use behaviors among PWD is lacking. This study examined the prevalence of opioid use behaviors by sociodemographic and health-related characteristics among PWD compared with people without disability (PWoD). METHODS: This cross-sectional study used data from 2015-2019 National Survey on Drug Use and Health. Three types of opioid use behaviors (any use, misuse, and use disorder) were defined and compared by disability status. Five self-reported disability types were measured, including hearing, vision, cognitive, mobility, and complex activity limitations. Complex survey design-adjusted descriptive and logistic regression models were used for statistical analysis. RESULTS: Of 201,376 respondents aged 18 years or older, 34.6% reported any opioid use, 4.2% opioid misuse, and 0.8% opioid use disorder. Compared with PWoD, PWD had higher prevalence of any opioid use (49.7% vs 30.7%), misuse (6.2% vs 3.7%), and use disorder (1.7% vs 0.8%). In adjusted analysis, PWD with mobility limitation (odds ratio [OR], 1.95; 95% confidence interval, 1.81-2.11) or multiple limitations (OR, 1.92; 95% CI, 1.83-2.02) were almost 2 times more likely to report any opioid use than PWoD. The likelihood of reporting any opioid use (ORs, 1.42-2.50), misuse (ORs, 1.24-2.41), and disorder (ORs, 1.38-2.54) increased as the number of limitations increased. CONCLUSIONS: People with vision, cognitive, or multiple limitations had higher rates of opioid misuse and disorder than PWoD. Development of more inclusive opioid abuse prevention strategies for PWD is warranted.

Background: Head and neck cancer (HNC) is a profoundly distressing condition that can have significant psychological implications. It has the potential to impact various fundamental aspects of an individual's life, resulting in functional impairments and structural deformities depending on the location, size, and route of spread, therefore causing significant disability. Yet, this has not been adequately studied. People residing around areas around the atomic radiation power plant are exposed to radiation, and also, contamination of water sources, including the Chambal River, which is a major source of water needs of this area, may have a role in the pathogenesis and prognosis of cancer patients. Aim: This study aimed to study disability in patients with head and neck cancer before and after radiotherapy. Materials and Methods: This prospective observational study was conducted in association with the Department of Radiotherapy of a tertiary care hospital in Rajasthan. Fifty consecutive HNC patients aged 18 to 65 years fulfilling inclusion criteria, specifically laid down for the study, constituted the sample of the study. The World Health Organization Disability Assessment Schedule version 2.0 (WHODAS-2.0) was used. Results: The mean age of patients was 49.62 years. A statistically significant improvement after radiotherapy was found in disability scores in domains of cognition (2.39 vs. 1.88), self-care (2.39 vs. 1.78), and getting along with people domain (2.38 vs. 1.83). Conclusion: Disability improved significantly in patients after radiotherapy in the domains of self-care, getting along with people, and cognition.
RESUMO
Background: About 1.5 lakh students study in over 100 coaching centers in Kota. There is a highly competitive environment, and students often land up in stress and even suicide. So, the estimation of the magnitude of this problem and timely intervention can be of great value to students. Aim: This study aimed to assess and compare stress and coping strategies used by coaching and non-coaching students studying in Kota. Material and Methods: This cross-sectional study included 90 coaching and 90 non-coaching students fulfilling inclusion criteria that were specifically laid down for the study. A semi-structured specially designed pro forma, Scale of Academic Stress (SAS), and Coping Strategies Scale (CSS)-Hindi version were used. Appropriate statistical methods were then used to classify, tabulate, and analyze the collected data. Results: In this study, it was found that of all coaching students, 44.45% were suffering from high levels of academic stress, 34.44% suffered from average and 21.11% reported suffering from low levels of academic stress. Likewise, among non-coaching students, 70% were suffering from low academic stress, 26.67% from average, and 3.33% from high levels of academic stress. It was also evident that the majority of both coaching and non-coaching students used a low level of active coping strategy (cognitive approach, behavioral approach, and cognitive behavioral approach) and a high level of avoidance coping strategy (cognitive avoidance and behavioral avoidance). Conclusion: There is a significantly high prevalence of stress among coaching students as compared to non-coaching students. Stress levels of greater severity were found to be more prevalent in female students, 12th-class students, those belonging to urban and middle-class backgrounds, and those whose stream was chosen by their parents. Both coaching and non-coaching students used the same type of coping strategies to cope with stress.
RESUMO
BACKGROUND: Lack of clinical trial awareness has been identified as a barrier to clinical trial recruitment. Identifying factors associated with clinical trial knowledge could inform ongoing efforts to improve diversity in clinical trials. METHODS: Using data from the Health Information National Trends Survey, 2020, we examined the knowledge of clinical trials, associated characteristics, sources of clinical trial information and motives to participate in clinical trials among the general population in the USA. RESULTS: Of 3,772 US adults, 41.3% reported not knowing about clinical trials. Prevalence of having no knowledge of clinical trials was higher among Hispanic adults (51.8%) and non-Hispanic Black adults (41.8%) compared with non-Hispanic White adults (37.4%; p=0.013). Other significant predictors of knowledge about clinical trials included higher education, online health information-seeking behaviour and patient portal access. Most respondents (73.2%) reported that healthcare providers were the most trusted source of information. Helping other people (71.6%) was the primary motivation for clinical trial participation, followed by financial compensation (12.5%) and receiving better treatment (5.1%). CONCLUSION: There is a gap in knowledge about clinical trials among the US population. Development of multimodal approaches, including online and offline information broadcasting, is needed to improve knowledge and clinical trial recruitment in diverse populations.

The unprecedented clinical success of Chimeric Antigen Receptor (CAR) T cell therapy in hematological malignancies has led researchers to study its role in solid tumors. Although, its utility in solid tumors especially in neuroblastoma has begun to emerge, preclinical studies of its efficacy in other solid tumors like osteosarcomas or gliomas has caught the attention of oncologist to be tried in clinical trials. Malignant high-grade brain tumors like glioblastomas or midline gliomas in children represent some of the most difficult malignancies to be managed with conventionally available therapeutics, while relapsed gliomas continue to have the most dismal prognosis due to limited therapeutic options. Innovative therapies such as CAR T cells could give an additional leverage to the treating oncologists by potentially improving outcomes and ameliorating the toxicity of the currently available therapies. Moreover, CAR T cell therapy has the potential to be integrated into the therapeutic paradigm for aggressive gliomas in the near future. In this review we discuss the challenges in using CAR T cell therapy in brain tumors, enumerate the completed and ongoing clinical trials of different types of CAR T cell therapy for different brain tumors with special emphasis on glioblastoma and also discuss the future role of CAR T cells in Brain tumors.

The aggressive and recurrent nature of glioblastoma is multifactorial and has been attributed to its biological heterogeneity, dysfunctional metabolic signaling pathways, rigid blood-brain barrier, inherent resistance to standard therapy due to the stemness property of the gliomas cells, immunosuppressive tumor microenvironment, hypoxia and neoangiogenesis which are very well orchestrated and create the tumor's own highly pro-tumorigenic milieu. Once the relay of events starts amongst these components, eventually it becomes difficult to control the cascade using only the balanced contemporary care of treatment consisting of maximal resection, radiotherapy and chemotherapy with temozolamide. Over the past few decades, implementation of contemporary treatment modalities has shown benefit to some extent, but no significant overall survival benefit is achieved. Therefore, there is an unmet need for advanced multifaceted combinatorial strategies. Recent advances in molecular biology, development of innovative therapeutics and novel delivery platforms over the years has resulted in a paradigm shift in gliomas therapeutics. Decades of research has led to emergence of several treatment molecules, including immunotherapies such as immune checkpoint blockade, oncolytic virotherapy, adoptive cell therapy, nanoparticles, CED and BNCT, each with the unique proficiency to overcome the mentioned challenges, present research. Recent years are seeing innovative combinatorial strategies to overcome the multifactorial resistance put forth by the GBM cell and its TME. This review discusses the contemporary and the investigational combinatorial strategies being employed to treat GBM and summarizes the evidence accumulated till date.
Glioblastoma is a form of brain tumor which typically leads to death in almost all patients. Over the last two decades, traditional treatment strategies such as surgery, radiotherapy and chemotherapy have been combined as standard therapy. Together, these aggressive treatment strategies have provided modest survival benefit with acceptable toxicity. However, relapse is the invariable norm resulting in death in the overwhelming majority of patients. Relapse occurs due to multiple factors such as inability of drugs to cross bloodbrain barrier, immunosuppressive tumor microenvironment, stemness nature of glioma cells, tumor heterogeneity and enhanced hypoxia and angiogenic factors. Therefore, there is an urgent need to develop an innovative treatment approach to treat glioblastoma. Recently, several treatment strategies known as immunotherapies including CAR T cell therapy, dendritic cell vaccines, immune checkpoints blockade and oncolytic virus, nano particles and gene editing/silencing technology have demonstrated promising results in preclinical and few clinical trials. Furthermore, to increase the efficacy of these novel strategies, combinatorial approaches are being implemented for the treatment. This includes CAR T cell therapy in combination with small molecules, immune checkpoint inhibitors and oncolytic virus and nanoparticles plus gene editing, silencing or immune checkpoints inhibitors. These treatments have shown exciting results in preclinical settings and few of these trials are in progress. The review summarizes these combinatorial novel approaches and discusses them in detail.

Importance: Bariatric surgery effectively treats severe obesity and metabolic diseases. However, individual outcomes vary depending on sustainable lifestyle change. Little is known about lifestyle patterns after bariatric surgery among the US population. Objective: To compare the level of physical activity and eating behavior among postbariatric surgery patients, individuals eligible for surgery, and those with normal weight. Design, Setting, and Participants: A cross-sectional study using nationally representative survey data from National Health and Nutrition Examination Survey 2015-2018. Respondents included for analysis were age 18 years or older, and categorized by individuals with normal weight, individuals who received bariatric surgery, and individuals clinically eligible for bariatric surgery. Analyses were performed from February to October 2021. Main Outcomes and Measures: Self-reported measures were used to assess physical activity (moderate-to-vigorous physical activity [MVPA], sedentary activity, and whether PA guidelines were met) and eating behaviors (total energy intake and Healthy Eating Index [HEI]-2015 diet quality scores). Results: Of 4659 study participants (mean [SD] age, 46.1 [18.6] years; 2638 [weighted percentage, 58.8%] women; 1114 [weighted percentage, 12.7%] Black, 1570 [weighted percentage, 68.6%] White), 132 (3.7%) reported that they had undergone any bariatric surgery. Median (IQR) time since surgery was 7 (3-10) years. After propensity-score weighting, individuals who underwent bariatric surgery reported more time spent in MVPA than those eligible for surgery (147.9 min/wk vs 97.4 min/wk). Among respondents with normal weight, 45.6% (95% CI, 40.8% to 52.4%) reported meeting PA guidelines, almost 2 times higher than those in the bariatric surgery (23.1%; 95% CI, 13.8% to 32.4%) or in the surgery-eligible group (20.3%; 95% CI, 15.6% to 25.1%). Propensity-score weighted overall HEI was higher for individuals with normal weight (54.4; 95% CI, 53.0 to 55.9) than those who underwent bariatric surgery (50.0; 95% CI, 47.2 to 52.9) or were eligible for the surgery (48.0; 95% CI, 46.0 to 50.0). Across all HEI components, mean scores were similar between the bariatric surgery and surgery-eligible groups. Total energy intake was the lowest among those who underwent bariatric surgery (1746 kcal/d; 95% CI, 1554 to 1937 kcal/d), followed by those with normal weight (1943 kcal/d; 95% CI, 1873 to 2013 kcal/d) and those eligible for bariatric surgery (2040 kcal/d; 1953 to 2128 kcal/d). Conclusions and Relevance: In this cross-sectional study, individuals who underwent bariatric surgery had beneficial lifestyle patterns compared with those eligible for surgery; however, these improvements seemed suboptimal based on the current guidelines. Efforts are needed to incorporate benefits of physical activity and a healthy, balanced diet in postbariatric care.

This paper discloses the efficient palladium-catalyzed anti-Markovnikov oxidative acetalization of activated terminal olefins with iron(III) sulfate as the reoxidant. This methodology requires mild reaction conditions and shows high regioselectivity toward anti-Markovnikov products and compatibility with a wide range of functional groups. Iron(III) sulphate was the sole reoxidant used in this method. Various olefins like vinylarenes, aryl-allylethers, aryl or benzyl acrylates and homoallylic alcohols all reacted well providing anti-Markovnikov acetals, some of which represent orthogonally functionalized 1,3- and 1,4-dioxygenated compounds.
RESUMO
BACKGROUND: Smoking remains a major contributor to mortality and morbidity. Dental care professionals are positioned to help patients quit smoking. Results of clinical trials have shown the efficacy of dental care professionals' smoking-cessation advice; however, the evidence of its effectiveness in the general population in the United States is limited. The authors examined the association between smoking-cessation advice from dental care professionals and quitting behaviors of adult smokers in the general population. METHODS: The authors used an observational study design with data from the National Health and Nutrition Examination Survey for the years 2015 through 2018. The authors included 1,024 respondents 18 years and older who were current or former smokers who quit smoking within the past 12 months and reported a dental visit within the past 12 months. RESULTS: Among the study sample, 44.6% received smoking-cessation advice from a dental care professional. The authors found no significant association between smoking-cessation advice and any attempt to quit smoking (as a binary outcome; adjusted odds ratio, 1.11; 95% CI, 0.68 to 1.80; P = .677). Although respondents who received smoking-cessation advice reported 18% more quit attempts (on a continuous scale; adjusted rate ratio, 1.18; 95% CI, 1.00 to 1.39, P = .05), smoking-cessation advice was not associated with smoking abstinence beyond 6 months. CONCLUSIONS: Receiving smoking-cessation advice from a dental care professional was associated with more attempts to quit smoking but not with abstinence of 6 months or longer. PRACTICAL IMPLICATIONS: Additional efforts seem to be needed for smoking cessation in dental practices. Implementing enhanced incentive programs or promoting tobacco-use cessation certification in dental education may be an effective strategy to enhance dental professionals' knowledge and skills in providing additional support to their patients.

Aberrant alternative splicing is recognized to promote cancer pathogenesis, but the underlying mechanism is yet to be clear. Here, in this study, we report the frequent upregulation of SRSF10 (serine and arginine-rich splicing factor 10), a member of an expanded family of SR splicing factors, in the head and neck cancer (HNC) patients sample in comparison to paired normal tissues. We observed that SRSF10 plays a crucial role in HNC tumorigenesis by affecting the pro-death, pro-survical splice variants of BCL2L1 (BCL2 Like 1: BCLx: Apoptosis Regulator) and the two splice variants of PKM (Pyruvate kinase M), PKM1 normal isoform to PKM2 cancer-specific isoform. SRSF10 is a unique splicing factor with a similar domain organization to that of SR proteins but functions differently as it acts as a sequence-specific splicing activator in its phosphorylated form. Although a body of research studied the role of SRSF10 in the splicing process, the regulatory mechanisms underlying SRSF10 upregulation in the tumor are not very clear. In this study, we aim to dissect the pathway that regulates the SRSF10 upregulation in HNC. Our results uncover the role of transcription factor EGR1 (Early Growth Response1) in elevating the SRSF10 expression; EGR1 binds to the promoter of SRSF10 and promotes TET1 binding leading to the CpG demethylation (hydroxymethylation) in the adjacent position of the EGR1 binding motif, which thereby instigate SRSF10 expression in HNC. Interestingly we also observed that the EGR1 level is in the sink with the ERK1/2 pathway, and therefore, inhibition of the ERK1/2 pathway leads to the decreased EGR1 and SRSF10 expression level. Together, this is the first report to the best of our knowledge where we characterize the ERK 1/2-EGR1-SRSF10 axis regulating the cancer-specific splicing, which plays a critical role in HNC and could be a therapeutic target for better management of HNC patients.
RESUMO
SIGNIFICANCE: Neuroretinitis classically presents with sudden vision loss, disc edema, and macular star formation. However, the classical triad may not always be seen, especially in the case of a pre-existing macular disorder. A thorough clinical examination may still clinch the appropriate diagnosis and prevent unwarranted treatment. PURPOSE: This study aimed to report a case of neuroretinitis in an adult woman with pre-existing type 2 macular telangiectasia where the classical pattern of exudation could not be seen. CASE REPORT: A 48-year-old woman, type 2 diabetic and hypertensive, presented with sudden painless blurring of vision in the right eye for the past 1 week. Macula in both eyes had loss of transparency and intraretinal crystalline deposits and pigments. The right eye had hyperemic edematous disc with peripapillary retinal hemorrhages and hard exudates. Color vision was grossly abnormal, and a centrocecal scotoma was noted on visual field analysis in the right eye. After a normal systemic evaluation, a diagnosis of right eye neuroretinitis and coexistent bilateral type 2 macular telangiectasia (nonproliferative type) was made. Unilateral painless visual loss, severe dyschromatopsia, and peripapillary hard exudates pointed to the correct diagnosis of neuroretinitis. Observation was advised, and visual acuity improved spontaneously. The disc edema resolved with consequent optic atrophy. CONCLUSIONS: Absence of the classical "macular star" appearance does not refute the diagnosis of neuroretinitis when pre-existing maculopathy is present.
