UNLABELLED: Patients with H3K27M-mutant diffuse midline glioma (DMG) have no proven effective therapies. ONC201 has recently demonstrated efficacy in these patients, but the mechanism behind this finding remains unknown. We assessed clinical outcomes, tumor sequencing, and tissue/cerebrospinal fluid (CSF) correlate samples from patients treated in two completed multisite clinical studies. Patients treated with ONC201 following initial radiation but prior to recurrence demonstrated a median overall survival of 21.7 months, whereas those treated after recurrence had a median overall survival of 9.3 months. Radiographic response was associated with increased expression of key tricarboxylic acid cycle-related genes in baseline tumor sequencing. ONC201 treatment increased 2-hydroxyglutarate levels in cultured H3K27M-DMG cells and patient CSF samples. This corresponded with increases in repressive H3K27me3 in vitro and in human tumors accompanied by epigenetic downregulation of cell cycle regulation and neuroglial differentiation genes. Overall, ONC201 demonstrates efficacy in H3K27M-DMG by disrupting integrated metabolic and epigenetic pathways and reversing pathognomonic H3K27me3 reduction. SIGNIFICANCE: The clinical, radiographic, and molecular analyses included in this study demonstrate the efficacy of ONC201 in H3K27M-mutant DMG and support ONC201 as the first monotherapy to improve outcomes in H3K27M-mutant DMG beyond radiation. Mechanistically, ONC201 disrupts integrated metabolic and epigenetic pathways and reverses pathognomonic H3K27me3 reduction. This article is featured in Selected Articles from This Issue, p. 2293.

Imaging response assessment is a cornerstone of patient care and drug development in oncology. Clinicians/clinical researchers rely on tumor imaging to estimate the impact of new treatments and guide decision making for patients and candidate therapies. This is important in brain cancer, where associations between tumor size/growth and emerging neurological deficits are strong. Accurately measuring the impact of a new therapy on tumor growth early in clinical development, where patient numbers are small, would be valuable for decision making regarding late-stage development activation. Current attempts to measure the impact of a new therapy have limited influence on clinical development, as determination of progression, stability or response does not currently account for individual tumor growth kinetics prior to the initiation of experimental therapies. Therefore, we posit that imaging-based response assessment, often used as a tool for estimating clinical effect, is incomplete as it does not adequately account for growth trajectories or biological characteristics of tumors prior to the introduction of an investigational agent. Here, we propose modifications to the existing framework for evaluating imaging assessment in primary brain tumors that will provide a more reliable understanding of treatment effects. Measuring tumor growth trajectories prior to a given intervention may allow us to more confidently conclude whether there is an anti-tumor effect. This updated approach to imaging-based tumor response assessment is intended to improve our ability to select candidate therapies for later-stage development, including those that may not meet currently sought thresholds for "response" and ultimately lead to identification of effective treatments.

Alternative lengthening of telomeres (ALT) is a homologous recombination-based telomere maintenance mechanism. It is active in approximately 10-15% of cancers. We present a DNA-fiber protocol, combining YOYO-1 staining of genomic DNA, telomere fluorescence in situ hybridization (FISH), and EdU labeling of nascent DNA, to measure telomere extension events in ALT cancer cells. The protocol can be used to delineate ALT-mediated telomere extension. For complete details on the use and execution of this protocol, please refer to Barroso-Gonzalez et al. (2021).

BackgroundGlioblastoma (GBM) is the deadliest of all brain cancers in adults. The current standard-of-care is surgery followed by radiotherapy and temozolomide, leading to a median survival time of only 15 months. GBM are organized hierarchically with a small number of glioma-initiating cells (GICs), responsible for therapy resistance and tumor recurrence, suggesting that targeting GICs could improve treatment response. ONC201 is a first-in-class anti-tumor agent with clinical efficacy in some forms of high-grade gliomas. Here we test its efficacy against GBM in combination with radiation.MethodsUsing patient-derived GBM lines and mouse models of GBM we test the effects of radiation and ONC201 on GBM self-renewalin vitro and survivalin vivo.A possible resistance mechanism is investigated using RNA-Sequencing.ResultsTreatment of GBM cells with ONC201 reduced self-renewal, clonogenicity and cell viabilityin vitro. ONC201 exhibited anti-tumor effects on radioresistant GBM cells indicated by reduced self-renewal in secondary and tertiary glioma spheres. Combined treatment of ONC201 and radiation prolonged survival in syngeneic and patient-derived orthotopic xenograft mouse models of GBM. Subsequent transcriptome analyses after combined treatment revealed shifts in gene expression signatures related to quiescent GBM populations, GBM plasticity, and GBM stem cells.ConclusionsOur findings suggest that combined treatment with the DRD2/3 antagonist ONC201 and radiation improves the efficacy of radiation against GBMin vitroandin vivothrough suppression of GICs without increasing toxicity in mouse models of GBM. A clinical assessment of this novel combination therapy against GBM is further warranted.

AbstractAcademic procrastination is one of the main problems students encounter during studying. It affects their mental health, academic performance, and even everyday activities. A lack of time management was once thought to be the cause of procrastination. Procrastination, however, has been linked to mood control, according to recent studies. Decision-making is also a factor that is influenced by emotion or a person’s affect. The present study aims to find whether decision-making and affective styles influence academic procrastination among Indian students. The participants (N = 211) who are currently studying any discipline in a regular mode and who are between the ages of 17 to 30 years (mean = 21.10 & SD = 2.168) were selected using purposive sampling, and data was collected online using Academic Procrastination Scale, General Decision-Making Style Instrument and Affective Style Questionnaire. Data were analyzed using Pearson correlation, along with multiple regression analysis. Results found a significant inverse correlation between rational decision-making and academic procrastination and a weak inverse correlation between adjusting affective style and academic procrastination. A significant positive correlation between avoidant decision-making and academic procrastination was also found. Through regression analysis avoidance, decision-making has been found as a positive predictor of academic procrastination along with rational decision-making, and spontaneous decision-making as negative predictors. No significant correlations were found for academic procrastination with intuitive, dependent, spontaneous, concealing, and tolerating styles. The current results contribute to the existing literature on academic procrastination and the development of effective strategies to reduce academic procrastination by managing unhealthy decision-making styles.

AbstractBoth hedonia and eudaimonia contribute to well-being, but existing literature on alcohol-dependence concentrates on hedonic needs alone, leaving a research gap on the role of eudaimonia in alcohol-dependence. Theoretically, mindfulness promotes eudaimonia that presumably benefits individuals with alcohol-dependence, but the empirical literature on the same is scarce. Hence, the current pilot study intended to examine the association of eudaimonia and mindfulness with alcohol-dependence, and assess the feasibility of the main study. Study-I compared mindfulness and eudaimonia of individuals with (N = 154) and without (N = 160) alcohol-dependence. Its results called forth a study-II that explored the role of eudaimonia and mindfulness in predicting alcohol-dependence among the individuals undergoing treatment for alcohol-dependence (N = 110). The data were analyzed using the independent-sample t-test, Pearson correlation, and multiple linear regression. Study-I revealed the significant deficiency of mindfulness and eudaimonia among individuals with alcohol-dependence compared to those without alcohol-dependence. Study-II found that mindfulness and eudaimonia predicted alcohol-dependence and alcohol craving. Study result indicates the potential role of mindfulness and eudaimonia in the effective treatment of alcohol-dependence, through significant correlation among the variables. The study also highlights the feasibility and utility of the main study.

Abstract Background India, the seventh-largest country in the world and the second-most populated faces enormous challenges when it comes to healthcare. The country’s healthcare system was close to collapse due to the detrimental effects of the COVID-19 pandemic. Telehealth, which enables treating patients remotely, played a critical role during these challenging times. This systematic review investigates in detail the role of telehealth during COVID-19 and its application beyond the pandemic. Methods Database searches on PubMed, Scopus, Science Direct and Web of Science were carried out for studies published on telehealth, and articles were included if they focused on any audio or video telehealth consultation during the pandemic in India. Findings were synthesised into three main themes: applications, benefits and challenges of telehealth services. Methodological quality was assessed using JBI critical appraisal tools. Results The initial search on databases yielded 1143 articles. Of those, 19 met the eligibility criteria. Findings highlight the effective utilisation of telehealth across multiple medical specialities. Although insufficient technological infrastructure and other barriers due to the virtual consultation challenge the successful implementation of telehealth in India, it has the potential to bridge the rural-urban healthcare divide with cost-effective and easily accessible services. Conclusion High patient/provider satisfaction underscores the need to integrate telehealth into routine healthcare practices in the country. However, the review urges the government and healthcare practitioners to address the telehealth challenges with prime importance to ensure quality healthcare throughout the nation even after the pandemic.

In tertiary education, generic professional skills should be developed along with discipline-specific knowledge and skills. Team-Based Learning (TBL), an active learning strategy, creates deep learning and enhanced student engagement; however, its effects on the development of generic learning outcomes are unknown. The aim of this study was to evaluate postgraduate specialty nursing students' perspectives of how TBL impacts the acquisition of skills defined by the university's eight Graduate Learning Outcomes (GLOs). A descriptive exploratory design was used in this study. Postgraduate nursing students in 2016-2017 at one university were invited to participate. Data were collected via demographic survey, a ranking tool, and written reflections. Data were analysed using descriptive statistics and content analysis. The response rate was 97.2 per cent (172/177). Participants were mostly females (n=152, 88.4%) aged 25-34 years (n=115, 66.9%). Student (n=156) rankings showed TBL contributed to the acquisition of critical thinking (n=90, 57.7%) and problem solving skills (n=56, 35.9%) the most. Students (n=144) made 2719 comments regarding how TBL led to the acquisition of GLOs in written reflections. Almost 98 per cent (n=2657) of all reflective comments were positive. All students mentioned at least one GLO positively due to TBL. Most positive reflections related to self-management (n=520, 19.6%) and communication (n=434, 16.3%). Postgraduate specialty nursing students perceived TBL classes contributed to the acquisition of their university's GLOs, particularly critical thinking, problem solving, and self-management skills. The active learning strategy of TBL facilitates learning and engagement, and the attainment of essential professional attributes which are highly valued by employers.

BACKGROUND: H3 K27M-mutant diffuse midline glioma is a fatal malignancy with no proven medical therapies. The entity predominantly occurs in children and young adults. ONC201 is a small molecule selective antagonist of dopamine receptor D2/3 (DRD2/3) with an exceptional safety profile. Following up on a durable response in the first H3 K27M-mutant diffuse midline glioma patient who received ONC201 (NCT02525692), an expanded access program was initiated. METHODS: Patients with H3 K27M-mutant gliomas who received at least prior radiation were eligible. Patients with leptomeningeal spread were excluded. All patients received open-label ONC201 orally once every week. Safety, radiographic assessments, and overall survival were regularly assessed at least every 8 weeks by investigators. As of August 2018, a total of 18 patients with H3 K27M-mutant diffuse midline glioma or DIPG were enrolled to single patient expanded access ONC201 protocols. Among the 18 patients: seven adult (> 20 years old) and seven pediatric (< 20 years old) patients initiated ONC201 with recurrent disease and four pediatric patients initiated ONC201 following radiation, but prior to disease recurrence. FINDINGS: Among the 14 patients with recurrent disease prior to initiation of ONC201, median progression-free survival is 14 weeks and median overall survival is 17 weeks. Three adults among the 14 recurrent patients remain on treatment progression-free with a median follow up of 49.6 (range 41-76.1) weeks. Among the 4 pediatric patients who initiated adjuvant ONC201 following radiation, two DIPG patients remain progression-free for at least 53 and 81 weeks. Radiographic regressions, including a complete response, were reported by investigators in a subset of patients with thalamic and pontine gliomas, along with improvements in disease-associated neurological symptoms. INTERPRETATION: The clinical outcomes and radiographic responses in these patients provide the preliminary, and initial clinical proof-of-concept for targeting H3 K27M-mutant diffuse midline glioma with ONC201, regardless of age or location, providing rationale for robust clinical testing of the agent.

Objective Chronic low back pain (CLBP) is a prominent medical condition that can affect an individual at some point in their life time which could lead to poor quality of life (QOL). Low back pain has affected approximately 577 million individuals globally by 2017. The aim of the current systematic review is to synthesise the existing evidence on the factors influencing the QOL in individuals with CLBP and to identify strategies to improve their QOL. Method PubMed, ScienceDirect, PsychNet and Google Scholar were used to extract studies reporting quantitative relationships between QOL and its possible determinants in individuals having CLBP and the intervention strategies to improve QOL. Results 10,851 studies were initially identified and twenty-six studies which met the inclusion criteria were selected for the review. 21 studies reported relationship between QOL and potential determinants and five studies assessed the influence of interventions on QOL. Determinants were classified as kinesiophobia, fear avoidance belief, or pain belief; occupation-related factors; pain and disability; activity; personal factors including age, gender, employment status; and other psychological factors including anxiety, quality of sleep, and health locus of control. Intervention strategies including MBSR, Pilates method and Back School Programme improved QOL in individuals with CLBP. Conclusion Psychosocial factors as well as the physical status of the individual contributed to the QOL in individuals having CLBP.

Introduction: Non-communicable diseases such as ischemic heart disease, cancer, diabetes, and chronic respiratory diseases are the leading causes of death worldwide, and are associated with tobacco use. The ultimate goal of health professionals and researchers working to combat smoking's extremely harmful health effects is to prevent smoking initiation. Nearly 5500 new smokers are added each day, for a total of almost 2 million new smokers each year. The COM-B model's primary goal is to determine what needs to be done for a behaviour change to occur. Behaviour modification requires an understanding of the factors that drive behaviour. Aim: The current qualitative study intends to explore the factors affecting tobacco use initiation (TUI) using the COM-B model, given the relevance of investigating the factors affecting TUI and the model. Methods: The present qualitative study has used a directed content analysis approach. Seventeen participants who reported having started any kind of tobacco in the last six months were recruited in the study using a purposive sampling method to understand the factors affecting TUI. The data was collected through interviews, and all of the participants were from the Hyderabad-Karnataka region of Karnataka, India (a state which has been reported as having the highest prevalence of cigarette smoking in India). Results: Directed content analysis revealed six categories: psychological capabilities affecting TUI (lack of knowledge about adverse health effects of tobacco, behavioural control, and poor academic performance), physical capabilities affecting TUI (lack of better physical resilience), physical opportunities favouring TUI (tobacco advertisements, easy access of tobacco products, and favourite star smoke on screen), social opportunities favouring TUI (peer influence, tobacco use by parents, tradition of hospitality, tobacco use as a normal behaviour, and toxic masculinity), automatic motivation causal factors of TUI (affect regulation, risk taking behaviours and tobacco use for pleasure) and reflective motivation causal factors of TUI (perceived benefits of tobacco, risk perception, perceived stress, and compensatory health beliefs). Conclusion: Identifying the factors that influence TUI may help to limit or prevent people from smoking their first cigarette. Given the importance of preventing TUI, the findings of this study indicated the factors that influence TUI, which can be valuable in improving behaviour change processes.

The collapse of stalled replication forks is a major driver of genomic instability. Several committed mechanisms exist to resolve replication stress. These pathways are particularly pertinent at telomeres. Cancer cells that use Alternative Lengthening of Telomeres (ALT) display heightened levels of telomere-specific replication stress, and co-opt stalled replication forks as substrates for break-induced telomere synthesis. FANCM is a DNA translocase that can form independent functional interactions with the BLM-TOP3A-RMI (BTR) complex and the Fanconi anemia (FA) core complex. Here, we demonstrate that FANCM depletion provokes ALT activity, evident by increased break-induced telomere synthesis, and the induction of ALT biomarkers. FANCM-mediated attenuation of ALT requires its inherent DNA translocase activity and interaction with the BTR complex, but does not require the FA core complex, indicative of FANCM functioning to restrain excessive ALT activity by ameliorating replication stress at telomeres. Synthetic inhibition of FANCM-BTR complex formation is selectively toxic to ALT cancer cells.

Purpose: To report a case of bilateral exudative retinal detachments and panuveitis in a patient with multiple myeloma (MM). Case Report: A 54-year-old patient with non-proliferative diabetic retinopathy was referred with blurred vision and scotomas in both eyes (OU). Three months prior to the onset of ocular symptoms, he was diagnosed with systemic MM and was receiving chemotherapy. Clinical examination revealed best-corrected visual acuities of 20/80 OU, rare anterior chamber cell, 2+ vitreous cell, diffuse intraretinal hemorrhages, and exudative retinal detachments (RD). Optical coherence tomography of the macula showed central subretinal fluid with cystic intraretinal fluid OU. The findings were consistent with panuveitis and exudative RD in the setting of MM. He reported symptomatic improvement after plasmapheresis and oral prednisone initiation. Conclusion: Extensive, bilateral exudative RD and panuveitis are rare but potentially sight-threatening findings in patients with MM. [ABSTRACT FROM AUTHOR]

Aim(s): To explore the published research related to nurses' documentation and use of vital signs in recognising and responding to deteriorating patients. Design: Scoping review of international, peer‐reviewed research studies. Data Sources: Cumulative Index to Nursing and Allied Health Literature Complete, Medline Complete, American Psychological Association PsycInfo and Excerpta Medica were searched on 25 July 2023. Reporting Method: Preferred Reporting Items for Systematic Reviews and Meta‐Analyses extension for scoping reviews. Results: Of 3880 potentially eligible publications, 32 were included. There were 26 studies of nurses' vital sign documentation: 21 adults and five paediatric. The most and least frequently documented vital signs were blood pressure and respiratory rate respectively. Seven studies focused on vital signs and rapid response activation or afferent limb failure. Five studies of vital signs used to trigger the rapid response system showed heart rate was the most frequent and respiratory rate and conscious state were the least frequent. Heart rate was least likely and oxygen saturation was most likely to be associated with afferent limb failure (n = 4 studies). Conclusion: Despite high reliance on using vital signs to recognise clinical deterioration and activate a response to deteriorating patients in hospital settings, nurses' documentation of vital signs and use of vital signs to activate rapid response systems is poorly understood. There were 21studies of nurses' vital sign documentation in adult patients and five studies related to children. Implications for the profession and/or patient care: A deeper understanding of nurses' decisions to assess (or not assess) specific vital signs, analysis of the value or importance nurses place (or not) on specific vital sign parameters is warranted. The influence of patient characteristics (such as age) or the clinical practice setting, and the impact of nurses' workflows of vital sign assessment warrants further investigation. Patient or Public Contribution: No Patient or Public Contribution. [ABSTRACT FROM AUTHOR]

Abstract As per the reports of WHO, the COVID-19, first reported in December 2019, put the whole world in an unprecedented crisis and lingering uncertainty with innumerable deaths, generalised economic depression, unemployment, quarantine, unavoidable lockdown, and travel-ban that was imposed globally as a necessity to tackle the pandemic. Among the populace, the migrants were found to be one of the most vulnerable groups in this lockdown, as their very livelihood came to a complete standstill. This review-paper aims to investigate in detail the multiple facets of adversities the migrants went through in India during the lockdown and the socio-psychological impact of circular migration. Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, studies on migrant workers during COVID-19 and on circular migration were searched. Database searches on Scopus, PubMed, and PsychNet and manual searches on Google Scholar were carried out. From the initially identified 15,697 articles, 15 articles that met the inclusion criteria were chosen for review. The findings highlight the different plight of the migrants, who had the pressing need to head back home to safety despite the acute financial crisis and the travel problems. The poor quality of the relief camps with meagre rations and lack of facilities especially put the women and children in distress and generated a lot of psychosocial issues. The present study urges the mental health-care professionals to groom themselves for facing the challenges of a surge in mental illnesses by taking necessary measures. It also emphasises the need to establish a strong ethical alliance between the local population, health systems, local government mechanisms, and human rights associations in order to take a relook at the national migration policies.

The intensity and frequency of rapes and attempted sexual assaults on women, along with several unreported cases, are rising alarmingly in countries including India. National Crime Records Bureau in 2018 reported one rape every 15 min in India. Additionally, according to the NCRB data, up to 91 rapes were reported in the country on a single day. This scenario, therefore, calls for the immediate attention of the researchers to explore the factors that contribute to such crimes. The current qualitative study, hence, was intended to explore the socio-cultural and psychological factors associated with rape from the perspectives of men. The current study was conducted among 37 males between the ages of 18 and 25 years. The data were collected using semi-structured interviews. The thematic analysis threw light on the development of several main themes and sub-themes for socio-cultural and psychological factors associated with rape. The important main themes that emerged include attitude towards rape, sexual restriction, masculine dominance, westernization, lack of social support, exploitation, perception and attitude toward law, psychological impact, and childhood trauma. The study had identified several socio-cultural factors that possibly contribute to sexual aggression against women; the psychological consequences of rape on the victims; and the role of societal norms that indirectly result in increased incidents of sexual assaults. The results would facilitate recognition, development, and implementation of social interventions to control the prevalence of rape in the country.
