Clinical spectrum, biochemical profile and disease progression of Kennedy disease in an Indian cohort.

BACKGROUND: Kennedy disease (KD) is a slowly progressive lower motor neuron degenerative disease. The prevalence of KD is unknown in India. AIM: To describe the phenotypic and laboratory features of an Indian cohort of KD patients. METHODS: A retrospective study was done on seven genetically confirmed KD patients based on demographic, clinical and laboratory details. RESULTS: Mean age at onset and presentation was 37 ± 11.9 and 44.6 ± 13.5 years respectively. Progressive asymmetric proximal and distal limb weakness was the commonest symptom (57.1%). All patients had motor symptoms along with non-specific symptoms such as cramps from the onset. Easy fatigability, decremental response along with ptosis were noted in two patients, which was a novel finding. Gynaecomastia and tongue wasting with fasciculations were universal findings. All five patients with nerve conduction studies showed sensorimotor neuropathy. Magnetic resonance imaging muscle done in two patients showed a prominent moth-eaten appearance in the thigh and posterior leg compartment in one patient. The mean cytosine-adenine-guanine repeats were 44 ± 3.7, and there was no association between age of onset or severity with repeat length. Only one patient required an assistive device for ambulation after 15 years of symptom onset. CONCLUSIONS: This study showed phenotypic heterogeneity in the Indian cohort. The age of onset was earlier with a slowly progressive indolent course as compared with other ethnic cohorts. This highlights the importance of considering the KD diagnosis in patients with the indolent course and suspected ALS diagnosis even with ptosis and fatigability in an appropriate clinical context.

Neuropalliative Care Needs Checklist for Motor Neuron Disease and Parkinson's Disease: A Biopsychosocial Approach.

Objectives: Neurodegenerative disorders necessitate comprehensive palliative care due to their progressive and irreversible nature. Limited studies have explored the comprehensive assessment needs of this population. This present study is designed to develop a checklist for evaluating the palliative care needs of individuals with motor neuron disease (MND) and Parkinson's disease (PD). Materials and Methods: The checklist was created through an extensive literature review and discussions with stakeholders in neuropalliative. Feedback from six field experts led to the finalisation of the checklist, which comprised 53 items addressing the unique biopsychosocial needs of MND and PD. Sixty patient-caregiver dyads receiving treatment in a tertiary referral care centre for neurology in south India completed the checklist. Results: People with MND had more identified needs with speech, swallowing, and communication, while people with PD reported needs in managing tremors, reduced movements, and subjective feelings of stiffness. People denying the severity of the illness was found to be a major psychosocial issue. The checklist addresses the dearth of specific tools for assessing palliative care needs in neurodegenerative disorders, particularly MND and PD. By incorporating disease-specific and generic items, the checklist offers a broad assessment of patients' multidimensional needs. Conclusion: This study contributes to the area of neuropalliative care by developing the neuropalliative care needs checklist (NPCNC) as a valuable tool for assessing the needs of individuals with neurodegenerative diseases. Future research should focus on refining and validating the NPCNC with larger and more diverse groups, applicability in different contexts, and investigating its sensitivity to changes over time.

Identifying disparities in suicidal thoughts and behaviors among US adolescents during the COVID-19 pandemic.

BACKGROUND: Suicidal thoughts and behaviors (STBs) became more common among racial and ethnic minorities and sexual and gender minorities (SGM) during the COVID-19 pandemic relative to White and non-SGM adolescents. This study examines associations between pandemic-related stressors and STBs among a nationally representative sample of adolescents to identify vulnerable subpopulations. METHODS: We analyzed data from 6769 high school students using the 2021 Adolescent Behaviors and Experiences Survey. Pandemic-related stressors were assessed via seven items related to negative experiences (e.g., parent job loss; food insecurity) during the COVID-19 pandemic. Logistic regression analyses estimated the association between pandemic-related stressors and four outcomes: (1) sadness/hopelessness; (2) suicidal ideation; (3) suicide planning; and (4) recent suicide attempt (i.e., past 12 months). Interactions were modeled by sex, race/ethnicity, and sexual identity. RESULTS: A greater number of pandemic-related stressors was associated with higher odds for sadness and hopelessness (aOR: 1.55; 95% CI:1.44-1.67), suicidal ideation (aOR: 1.48; 95% CI:1.39-1.57), suicide planning (aOR:1.47; 95% CI: 1.36-1.59), and recent suicide attempt (aOR: 1.64; 95% CI:1.42-1.88). Pandemic-related stressors were also more strongly associated with some types of STBs in males (relative to females) and SGM females (relative to heterosexual females). CONCLUSION: Study findings indicate that pandemic-related stressors are associated with STBs within the US adolescent population, particularly among male and SGM female adolescents. Researchers are encouraged to use this knowledge to ensure nationwide suicide prevention efforts adequately address inequities in suicide risk.

Clinical, genetic profile and disease progression of sarcoglycanopathies in a large cohort from India: high prevalence of SGCB c.544A > C.

The clinico-genetic architecture of sarcoglycanopathies in Indian patients is reported only as short series. In the present study, we aimed to investigate the clinical picture, genetic basis, and disease progression of patients genetically confirmed to have sarcoglycanopathy. Next-generation sequencing was performed in 68 probands with suspected sarcoglycanopathy. A total of 35 different variants were detected in the sarcoglycan genes in 68 probands (M = 37; age range, 5-50 years). Consanguinity was present in 44 families. Thirty-two variants are predicted to be pathogenic/likely pathogenic, among which 25 (78.13%) are reported, and 7 (21.87%) are novel. The clinical diagnosis was confirmed in a total of 64 (94.12%) probands with biallelic variations [SGCA(n=18); SGCB(n=34); SGCG(n=7); SGCD(n=5)]. The most common mutation was c.544A > C (p.Thr182Pro) in SGCB, and detected in 20 patients (29.42%). The majority of pathogenic mutations are homozygous (n = 30; 93.75%). Variants in 4 cases are of uncertain significance. Thirty-three patients lost ambulation at a mean age of 15.12 ± 9.47 years, after 7.76 ± 5.95 years into the illness. Only 2 patients had cardiac symptoms, and one had respiratory muscle involvement. The results from this study suggest that mutations in SGCB are most common, followed by SGCA, SGCG, and SGCD. The novel variations identified in this study expand the mutational spectrum of sarcoglycanopathies. To the best of our knowledge, this is the first study from India to describe a large cohort of genetically confirmed patients with sarcoglycanopathy and report its disease progression.

Cognition, Behavior, and Caregiver Stress in Dementia during the COVID-19 Pandemic: An Indian Perspective.

OBJECTIVES: Little is known regarding the cognitive and behavioral status of patients with dementia and their caregivers in lower middle-income countries during the COVID-19 pandemic. This study aimed to understand the impact of the pandemic on persons with dementia and their caregivers in India. METHODS: This was an observational study. A cohort of 66 persons with dementia and their caregivers were evaluated during the COVID-19 pandemic in 2 specialist hospitals in South India. Caregivers were interviewed at 2 distinct time points of the pandemic: during the national lockdown and 5 months after during later periods of the "cluster of cases" transmission phase. Participants were assessed via telephone utilizing validated instruments (Neuropsychiatric Inventory [NPI], Clinical Dementia Rating [CDR] Scale, and Depression, Anxiety and Stress Scale [DASS-21]) and a semi-structured questionnaire. The questionnaire documented sociodemographic information, clinical history, infection measures adopted, changes in caregiving routines, involvement in functional rehabilitation activities, and access to medical and long-term care support services. RESULTS: The 2-phase follow-up study found a significant worsening of behavior in dementia patients, demonstrated by a difference in the NPI sub-domain scores for anxiety (mean difference [standard deviation, SD] = -0.552 [1.993], t58 = -2.109, p = 0.039) and eating disturbances (mean difference [SD] = -1.121 [2.493], t59 = -3.424, p = 0.001). A relatively high proportion of patients developed anxiety (cumulative incidence = 24.53%) and eating disturbances (cumulative incidence = 26.92%), without having these symptoms at baseline. There was a trend toward an increase in proportion of persons with severe dementia (19.7% vs. 39.4%) on follow-up. Caregiver distress reported was significantly associated with neuropsychiatric symptoms (r = 0.712, p < 0.001) and dementia severity (ρ = 0.365, p = 0.004). In addition, difficulties in accessing medical care persisted between the 2 assessments, and there were statistically significant differences between functional rehabilitation activities such as indoor activities (p < 0.001), outdoor activities (p = 0.013), and physical exercises (p = 0.003) between baseline and follow-up. CONCLUSION: Findings suggest interruption of functional rehabilitation activities and disruption in medical care services are likely to have had an adverse impact on patients with dementia and contributed toward caregiver distress.

In-Hospital Macro-, Meso-, and Micro-Drivers and Interventions for Antibiotic Use and Resistance: A Rapid Evidence Synthesis of Data from Canada and Other OECD Countries.

Hospitals continue to face challenges in reducing incorrect antibiotic use due to social and cultural factors at the level of the health system, the care facility, the provider, and the patient. The objective of this paper is to highlight the social and cultural drivers of antimicrobial use and resistance and targeted interventions for secondary and tertiary care settings in Canada and other OECD countries. This paper is an extension of the synthesis conducted for the Public Health Agency of Canada's 2019 Spotlight Report: Preserving Antibiotics Now and Into the Future. We conducted a systematic review with a few modifications to meet rapid timelines. We conducted a search in Ovid MEDLINE and McMaster University's evidence databases for systematic reviews and then for individual Canadian studies. To cast a wider net, we searched OECD organization websites and screened reference lists from systematic reviews. We synthesized the evidence narratively and categorized the evidence into macro-, meso-, and microlevel. A total of 70 studies were (a) from OCED countries and summarized evidence of potential sociocultural antimicrobial resistance and use barriers or facilitators and/or interventions addressing these challenges; (b) systematic reviews with 50% of included studies that are situated in secondary and tertiary settings; and (c) published in Canada's two official languages, English and French. We found that hospital structures and policies may influence antibiotic utilization and variations in antimicrobial management. Microlevel factors may sway inappropriate prescribing among clinicians. The amount and type of antibiotics used may affect resistance rates. Interventions were mainly comprised of antibiotic stewardship and training that modify clinician behavior and that educate patients and carers. This evidence synthesis illustrates the various drivers of, and interventions for, antimicrobial use and resistance at the macro-, meso-, and microlevel in secondary and tertiary settings. We demonstrate that upstream drivers may lead to downstream events that influence antimicrobial resistance.

Spatial aspects of pain modulation are not disrupted in adolescents with migraine.

OBJECTIVE: To compare spatial pain modulation capabilities between adolescents with and without migraine. BACKGROUND: Conditioned pain modulation (CPM) responses at the leg are similar in adolescents with versus without migraine. However, the anatomical region of testing may affect spatial pain modulation capabilities as differences in nociceptive processing between patients with migraine and healthy controls are found in local areas that are near the site of clinical pain but not in nonlocal areas. This study aimed to examine spatial pain modulation capabilities tested by the CPM paradigm using test stimulus applied to a local body area. METHODS: Nineteen adolescents with migraine (age 14.9 ± 2.3, mean ± SD; 16 female) and 20 healthy adolescents (age 13.8 ± 2.5, mean ± SD; 16 female) completed this case-control study at Cincinnati Children's Hospital Medical Center. Pressure pain thresholds (PPT) were assessed at the trapezius before and during immersion of the foot in a cold water bath (8°C). RESULTS: In the migraine group (146.0 ± 79.1, mean ± SD), compared to healthy controls (248.0 ± 145.5, mean ± SD), significantly lower PPT (kilopascal) values were found (estimate = 124.28, 95% CI: 58.98, 189.59, p < 0.001; effect size: d = 1.40). No differences between the groups were found for pain intensity and unpleasantness ratings of cold-water immersion nor the CPM response. CONCLUSIONS: This study found altered ascending nociceptive processing of mechanical stimuli at the neck in adolescents with migraine. However, endogenous pain modulatory mechanisms were functional and not altered. In light of other studies, impairments in inhibitory control may not be involved in migraine pathophysiology in pediatric patients regardless of stimulus location.

Clinical characteristics, treatment and long-term prognosis in patients with anti-NMDAR encephalitis.

OBJECTIVES: We aimed to (i) analyse the clinical characteristics, treatment outcome and long-term prognosis of anti-NMDAR encephalitis and (ii) study the differences between paediatric and adult patients. METHODS: This was a chart review of all patients with anti-NMDAR encephalitis. RESULTS: There were 28 patients with 18 patients belonging to the paediatric (<18 years) age group. There was female (94%) preponderance in the paediatric age group, while in adult patients, there was no gender predilection (p=0.006). There was no significant difference in clinical feature, outcome or number of relapses between paediatric and adult population groups. MRI brain was abnormal in 53% of patients. Among the 15 patients with MRI abnormalities at the onset, 53% had poor functional outcome at 1 year, while in 12 patients with normal initial MRI brain, only 8% had poor functional outcome at 1 year (p =0.01). Nearly 53% of patients with abnormal MRI at presentation had at least one clinical relapse within 2 years while in patients with normal MRI at presentation, 15% had a clinical relapse (p=0.037). EEG abnormalities were noticed in 71% of patients; among them, 40 and 15% had poor functional outcome at 1 and 2 years respectively. In comparison, those with normal first EEG at onset, 12% had poor functional outcome at 2 years (p=0.57). CONCLUSIONS: Both paediatric and adult patients presented with similar clinical features but the paediatric population had female preponderance. The functional outcome and number of relapse were comparable in both the paediatric and adult groups. Patients with parenchymal changes on MRI and abnormal EEG showed poorer response compared to those with normal MRI and/or EEG at the onset. Patients have lesser severity of symptoms at relapse than in the first episode. An early diagnosis and treatment are essential for better long-term functional outcome.

Integrated Home-Based Palliative Care in Motor Neuron Disease: A Case Report from Low- Middle Income Country.

In many international care guidelines, multidisciplinary palliative care forms a key to optimum management in Motor Neuron Disease (MND). We describe the home-based palliative care interventions for a client with MND and his family from a Low and Middle-income country context. This report also discusses the advantages and challenges of the same with suggestions for sustaining the quality of care for neuro palliative conditions.

Palliative Care in Duchenne Muscular Dystrophy: A Study on Parents' Understanding.

INTRODUCTION: Duchene muscular dystrophy (DMD) is a neuromuscular disease of childhood, which has clear progression. The international standardized care guidelines for DMD suggest that palliative care is essential for the affected children. OBJECTIVE: To explore the parent's understanding of palliative care services available for children with DMD and the challenges faced by them in utilizing the same. METHODS: A cross-sectional qualitative exploratory study was conducted among six families of boys diagnosed with DMD. A semi-structured interview guide with prompts was used to conduct in-depth interviews which lasted for an average of 1 h. Thematic analysis was done to identify the pattern or themes. RESULTS: The major themes identified were "palliative care, living with DMD, Awareness about palliative care services and challenges." Awareness about palliative care services is the dominant theme identified as influencing rest of the experiences narrated by the parents of children with DMD. DISCUSSION: Integration of palliative care services from an early stage of the illness can help the child to make transition from one stage to another stage of the illness. To ensure the utilization of the available palliative care services, there is a need to create awareness about it among the general public. CONCLUSION: Introducing the concept of palliation of symptoms and ensuring quality of life of the child with DMD by accessing the available services can aid the parents to reach out for help for their child.

Changes in salivary microbial sensing proteins CD14 and TLR2 with aging.

OBJECTIVE: Soluble toll-like receptor-2 (sTLR2) and soluble CD14 (sCD14) in saliva are defense proteins that bind specific microbe-associated molecular patterns. Since the oral flora changes with aging, the objective of this study is to determine and compare the concentration of sTLR2 and sCD14 in the saliva of healthy individuals in age groups from the first to the sixth decade of life. METHODS: Unstimulated whole saliva was collected after obtaining informed consent. The concentration of sCD14 and sTLR-2 was measured by enzyme-linked immunosorbent assay. Statistical differences between the age groups were determined by analysis of variance. The relationship between the two markers in each age group was evaluated by Pearson's correlation coefficient and linear regression analyses. RESULTS: The concentration of salivary sTLR2 was highest in the youngest, and that of the sCD14 was highest in the oldest age group. While the salivary sCD14 and the sTLR2 exhibited a moderate negative correlation in the youngest, the relationship between the two markers was inversed in the oldest age group. CONCLUSIONS AND CLINICAL RELEVANCE: The results of our exploratory study suggest a need to adjust for age-dependent changes in sCD14 and sTLR2 in healthy saliva while assessing the two proteins as biomarkers.

Lived Experience of Spouses of Persons with Motor Neuron Disease: Preliminary Findings through Interpretative Phenomenological Analysis.

INTRODUCTION: Motor neuron disease (MND) is a progressive neuromuscular disorder that can have significant and debilitating impact on the affected patient and families. Spouses are the primary carers for persons with MND in India, and the life of the person with MND and their spouse is never the same after the diagnosis. AIM: The objective was to explore the lived experience of spouses of persons diagnosed with MND. METHODS: A qualitative exploratory study with three-point interviews was conducted with spouse caregivers of two persons diagnosed with MND who were receiving treatment from a national tertiary referral care center for neurological disorders. All the patients were diagnosed as definite MND according to the modified El Escorial criteria. With the spouses, in-depth interviews were conducted at their home, lasting on an average of 1 hour using a semi-structured interview guide (prompts). Interpretative phenomenological analysis was used to derive themes from the interviews. RESULTS: The major themes emerged from the analysis were meaning of MND which contained the subthemes of delay in diagnosis and deterioration, psychological response across illness trajectory, relationship with the subthemes of changing roles in being acarer, marital relationship, to be seen as doing "right," and communication; adaptation with the subthemes of coping strategies and support system and life without the loved one. CONCLUSION: The changes in the lives of spouses and in strategies for caring the partner with deterioration of symptoms in the illness trajectory are explained in this study. The palliative approach in the management of MND has to take into account, the experiences and needs of carers since care happens at home.

Stress and perceived stigma among parents of children with epilepsy.

PURPOSE: The present study aimed at understanding the stress and perceived stigma among parents of children with epilepsy seeking treatment at a tertiary referral center for neurology in South India. MATERIALS AND METHODS: Parents of sixty children suffering from epilepsy in the age group of 4-15 years were interviewed to explore parental stress and perceived stigma. They were recruited consecutively over a period of 6 months in 2015. Tools administered were Childhood-Illness related Parenting Stress Inventory (Manford in J Neurol 264(8):1811-24, 2017) and the Parent Stigma Scale (Baca et al. in Value Health 13(6):778-786, 2010). RESULTS: The mean age of parents was 37.2 years, and the majority of parents who used to bring their child to the hospital were male (71.7%) and educated up to the secondary/intermediate level (36%) and were from lower socio-economic status. The mean age of children with epilepsy was 8.4 years with the majority of them being male (66.7%), affected with chronic seizures (58.3%) with most commonly occurring seizure type being generalized seizures (50%), with a co-morbid diagnosis of cerebral palsy (26.7%). A significant number of parents reported difficulty in communicating with medical team (58.3%) and significant others (51.7%) about their child's seizures and difficulty in making decisions related to their child's medical care (43.3%) which strained their financial resources and created difficulty in adequate role functioning. Findings indicated that most of the parents of children with chronic seizures perceived reactions of others to be negative (53.3%) and would limit family social interaction which resulted into emotional reaction in the form of anger, guilt, fear, anxiety, and depression. CONCLUSION: Parents are important figures in the process by which children with epilepsy came to acknowledge themselves being different from other children. Parents often feared divulging their child's epilepsy to their friends and relatives because they experienced a sense of shame, self-blame, and rejection which also increased their stress.

Family Caregivers' Experiences with Dying and Bereavement of Individuals with Motor Neuron Disease in India.

Motor neuron disease (MND) is a progressive neurodegenerative disease. Ideal management plan in MND includes palliative care initiated from the time of diagnosis. At present, most of the neurodegenerative conditions are cared for at home. Neuropalliative care is an emerging concept in India and social workers are integral team members in this process. The primary aims of the study were to explore (a) the caregivers' experiences of the end-of-life stage, and (b) the sources of support for individuals and their caregivers with MND at the end-of-life stage. In-depth interviews were conducted with seven bereaved caregivers of individuals with MND from a national tertiary referral care center for neuropsychiatry in South India. Interviews were conducted either in person or by telephone. Thematic analysis was done using the constant comparative method. Major themes derived from the interviews were: (1) Transition from person to patient, (2) support, (3) death, and (4) impact on the caregivers. Mapping of themes identified "Support received during advanced stages" as the central theme influencing all other themes. The need for a care manager seems evident and is a role that can be effectively fulfilled by the care teams' social workers.

Natural history of a cohort of Duchenne muscular dystrophy children seen between 1998 and 2014: An observational study from South India.

BACKGROUND: Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy. There are no large studies describing its natural course from India. MATERIALS AND METHODS: Immunohistochemically/genetically confirmed DMD patients diagnosed between 1998 and 2014 were ambispectively included. The main aim was to study the natural course of motor milestones, i.e., age at onset of wheelchair status, bedbound state, and age at death, which were considered as primary outcome measures. We also correlated the DMD genotype with the motor milestones and other phenotypic features. RESULTS: A total of 500 DMD patients were included and 275 participated in the study. The mean age at symptom onset was 3.7 ± 1.9 years, mean age at presentation was 8.1 ± 2.5 years, and mean duration of illness was 4.4 ± 2.6 years. On following them over 15 years, 155 (56.4%) had attained at least one of the primary outcome measures. Wheelchair status was attained in 124 (45.1%) [mean age: 10.4 ± 1.6 years] and bedbound state in 24 (8.7%; mean age: 11.8 ± 2.2 years) patients. Seven patients (2.6%) died during the follow-up period (mean age: 15.2 ± 2.4 years). There was no significant impact of the genotypic or phenotypic features on the primary outcome. CONCLUSION: The pattern of major motor milestones (primary outcome measures) in this large cohort is comparable with that of the Western population despite variability in medical care. The genotypic pattern was also similar to other large studies, which suggests that DMD is a more homogeneous disorder with limited ethnic variability in its geno-phenotypic expression.

Palliative Care Social Work In India: Current Status and Future Directions.

Palliative care (PC) involves total care for persons suffering from life-threatening illnesses and their families. Social work as a profession and an academic discipline is gaining momentum in India for the past few decades. A large number of professional social workers are working with individuals, families, and communities to provide PC in India. Authors have presented the current status of PC social work interventions and discussed the future directions in the practice, research, and training in PC and end-of-life care.

Room Temperature Ionic Liquids as Green Solvent Alternatives in the Metathesis of Oleochemical Feedstocks.

One of the most important areas of green chemistry is the application of environmentally friendly solvents in catalysis and synthesis. Conventional organic solvents pose a threat to the environment due to the volatility, highly flammability, toxicity and carcinogenic properties they exhibit. The recently emerged room temperature ionic liquids (RTILs) are promising green solvent alternatives to the volatile organic solvents due to their ease of reuse, non-volatility, thermal stability and ability to dissolve a variety of organic and organometallic compounds. This review explores the use of RTILs as green solvent media in olefin metathesis for applications in the oleochemical industry.

Past-year counseling and therapy use and severity of depression among university students with depression: The Healthy Minds Study.

Background: This exploratory study examined the associations between sociodemographic factors and past-year counseling or therapy use by depression severity among college students with depression. Participants: This cross-sectional analysis included n = 8090 participants from the Healthy Minds Study Winter 2021 Survey. Methods: Main effects and stratified multivariable logistic regression models assessed the relationship between sociodemographic factors and counseling/therapy independently and by depression severity. Results: Depression severity and counseling or therapy use were not independently associated (χ2 = 1.34, p = 0.77). Fourth + year students showed a graded response for past-year counseling/therapy use across depression severity (aOR range: 0.57-0.78, 95% CI range: 0.49-1.24). Males and students living with relatives, and those with stressful financial situations also showed lower odds of past-year counseling/therapy use. Conclusion: Findings indicate vulnerable subpopulations of college students that need support. Future interventions should identify barriers to treatment and pathways to support these students.

Expression profiling of signal transducer and activator of transcription3 in oral squamous cell carcinoma in south Indian population.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is widely acknowledged as the most prevalent form of oral malignancy. The annual identification of approximately 540,000 new cases of OSCC highlights its significant impact. The survival rate beyond 5 years postsurgery remains low. The role of signal transducer and activator of transcription3 (STAT3), a signaling protein involved in various cellular processes, has garnered attention. Aberrant activation of STAT3 has been implicated in OSCC progression and aggressiveness. Understanding the impact of STAT3 dysregulation on OSCC outcomes could provide valuable insights for developing targeted therapies. The aim of this study was to evaluate and compare the expression levels of STAT3 in OSCC and normal tissues of the same patients. METHODS: The expression levels of STAT3 in 63 OSCC samples were detected by qRT-PCR and compared to patient-matched-non-tumor oral tissues. Data were normalized to internal controls, and fold change in STAT3 expression was calculated using the ∆∆Ct method. Correlations between expression level and clinicopathologic characteristics like staging and grading of OSCC samples were also analyzed. RESULTS: Our findings demonstrated that STAT3 expression was significantly upregulated (P<0.0001) in OSCC patients compared to normal control tissue. Furthermore, we also observed a positive correlation between elevated STAT3 expression and higher OSCC histological grades when compared to the normal tissue. Well differentiated OSCC showed a slightly lower expression compared to the other two grades. CONCLUSIONS: Our results support the involvement of STAT3 in OSCC tumorigenesis. We propose that STAT3 might be used as a potential biomarker for OSCC. Further investigations are warranted to elucidate the mechanistic basis for the observed associations and to explore STAT3's potential as a therapeutic target in OSCC.

Mental Health Status by Race, Ethnicity and Socioeconomic Status among Young Adults in Texas during COVID-19.

BACKGROUND: Differences in symptoms of depression and anxiety by race/ethnicity and socioeconomic status (SES) among a diverse cohort of young adults during the COVID-19 pandemic (Spring 2020-Fall 2021) have not been examined. METHOD: We analyzed four waves of biannual, panel data from n = 2629 emerging adults (16-25 years old) from the Texas Adolescent Tobacco and Marketing Surveillance study (TATAMS). We conducted a series of mixed effects ordinal logistic regression models to compare the independent and joint effects of race/ethnicity and SES on symptoms of (a) depression and (b) anxiety, adjusting for sex, cohort, and time. RESULTS: Symptoms of depression (aOR range: 1.54 - 2.19; 95% CI: 1.02 - 3.08) and anxiety (aOR range: 1.64 - 2.19; 95% CI: 1.22 - 2.79) were elevated among low SES young adults, across all racial/ethnic groups. Across SES groups, symptoms of depression were lower among non-Hispanic Blacks compared to non-Hispanic Whites (aOR range: 0.33 - 0.41; 95% CI: 0.18 - 0.62) and Hispanics /Latinos (aOR range: 0.33 - 0.38; 95% CI: 0.20 - 0.57); similarly, symptoms of anxiety were lower among non-Hispanic Blacks compared to non-Hispanic Whites (aOR range: 0.44; 95% CI: 25 - 0.77) and Hispanics/Latinos (aOR range: 0.47 - 0.56; 95% CI: 0.29 - 0.83). No significant interaction (joint effect) was observed between SES and race/ethnicity during this period. CONCLUSION: Low SES was persistently related to poor mental health. Lower odds of symptoms of anxiety and depression among non-Hispanic Black young adults may reflect the 'mental health paradox'. Overall, mental health policies should prioritize lower SES young adults regardless of race and ethnicity.
