Post-acute COVID-19 syndrome (PCS) and health-related quality of life (HRQoL)-A systematic review and meta-analysis.

There is an established literature on the symptoms and complications of COVID-19 but the after-effects of COVID-19 are not well understood with few studies reporting persistent symptoms and quality of life. We aim to evaluate the pooled prevalence of poor quality of life in post-acute COVID-19 syndrome (PCS) and conducted meta-regression to evaluate the effects of persistent symptoms and intensive care unit (ICU) admission on the poor quality of life. We extracted data from observational studies describing persistent symptoms and quality of life in post-COVID-19 patients from March 10, 2020, to March 10, 2021, following PRISMA guidelines with a consensus of two independent reviewers. We calculated the pooled prevalence with 95% confidence interval (CI) and created forest plots using random-effects models. A total of 12 studies with 4828 PCS patients were included. We found that amongst PCS patients, the pooled prevalence of poor quality of life (EQ-VAS) was (59%; 95% CI: 42%-75%). Based on individual factors in the EQ-5D-5L questionnaire, the prevalence of mobility was (36, 10-67), personal care (8, 1-21), usual quality (28, 2-65), pain/discomfort (42, 28-55), and anxiety/depression (38, 19-58). The prevalence of persistent symptoms was fatigue (64, 54-73), dyspnea (39.5, 20-60), anosmia (20, 15-24), arthralgia (24.3, 14-36), headache (21, 3-47), sleep disturbances (47, 7-89), and mental health (14.5, 4-29). Meta-regression analysis showed the poor quality of life was significantly higher among post-COVID-19 patients with ICU admission (p = 0.004) and fatigue (p = 0.0015). Our study concludes that PCS is associated with poor quality of life, persistent symptoms including fatigue, dyspnea, anosmia, sleep disturbances, and worse mental health. This suggests that we need more research on PCS patients to understand the risk factors causing it and eventually leading to poor quality of life.

Stroke and HIV-associated neurological complications: A retrospective nationwide study.

There is an increased risk of stroke and other neurological complications in human immunodeficiency virus (HIV) infected patients with no large population-based studies in the literature. We aim to evaluate the prevalence of stroke, HIV-associated neurological complications, and identify risk factors associated with poor outcomes of stroke among HIV admissions in the United States. In the nationwide inpatient sample with adult HIV hospitalizations, patients with primary cerebrovascular disease (CeVDs) and HIV-associated neurological complications were identified by ICD-9-CM codes. We performed a retrospective study with weighted analysis to evaluate the prevalence of stroke and neurological complications and outcomes of stroke among HIV patients. We included 1,559,351 HIV admissions from 2003 to 2014, of which 22470 (1.4%) patients had CeVDs (transient ischemic attack [TIA]: 3240 [0.2%], acute ischemic stroke [AIS]: 14895 [0.93%], and hemorrhagic stroke [HS]: 4334 [0.27%]), 7781 (0.49%) had neurosyphilis, 29,925 (1.87%) meningitis, 39,190 (2.45%) cytomegalovirus encephalitis, 4699 (0.29%) toxoplasmosis, 9964 (0.62%) progressive multifocal leukoencephalopathy, and 142,910 (8.94%) epilepsy. There is increased overall prevalence trend for CeVDs (TIA: 0.17%-0.24%; AIS: 0.62%-1.29%; HS: 0.26%-0.31%; pTrend < .0001) from 2003 to 2014. Among HIV admissions, variables associated with AIS were neurosyphilis (odds ratio: 4.38; 95% confidence interval: 3.21-5.97), meningitis (4.87 [4.10-5.79]), and central nervous system tuberculosis (6.72 [3.85-11.71]). Toxoplasmosis [4.27 [2.34-7.76]), meningitis (2.91 [2.09-4.06)], and cytomegalovirus encephalitis (1.62 [1.11-2.37]) were associated with higher odds of HS compared to patients without HS. There was an increasing trend of CeVDs over time among HIV hospitalizations. HIV-associated neurological complications were associated with the risk of stroke, together with increased mortality, morbidity, disability, and discharge to long-term care facilities. Further research would clarify stroke risk factors in HIV patients to mitigate adverse outcomes.

Obesity a predictor of outcomes of COVID-19 hospitalized patients-A systematic review and meta-analysis.

Coronavirus disease 2019 (COVID-19) pandemic is a global health crisis. Very few studies have reported association between obesity and severity of COVID-19. In this meta-analysis, we assessed the association of obesity and outcomes in COVID-19 hospitalized patients. Data from observational studies describing the obesity or body mass index and outcomes of COVID-19 hospitalized patients from December 1, 2019, to August 15, 2020, was extracted following PRISMA guidelines with a consensus of two independent reviewers. Adverse outcomes defined as intensive care units, oxygen saturation less than 90%, invasive mechanical ventilation, severe disease, and in-hospital mortality. The odds ratio (OR) and 95% confidence interval (95% CI) were obtained and forest plots were created using random-effects models. A total of 10 studies with 10,233 confirmed COVID-19 patients were included. The overall prevalence of obesity in our study was 33.9% (3473/10,233). In meta-analysis, COVID-19 patient with obesity had higher odds of poor outcomes compared with better outcomes with a pooled OR of 1.88 (95% CI: 1.25-2.80; p = 0.002), with 86% heterogeneity between studies (p < 0.00001). Our study suggests a significant association between obesity and COVID-19 severity and poor outcomes. Our results findings may have important suggestions for the clinical management and future research of obesity and COVID-19.

Natural History of Chronic Hepatitis B Infection Among Chinese Children and Young Adults: A Single-Center Experience.

OBJECTIVES: There are limited data on the natural history of chronic hepatitis B virus (HBV) infection in Asian American children. The aim of the present study was to describe a single-center experience of chronic HBV infection in Chinese American patients in New York City. METHODS: A retrospective chart review was conducted for patients with chronic HBV infection who had pediatric visits from 2006 to 2017. Clinical and laboratory data were collected to characterize the status of HBV infection and its disease course both cross-sectionally and longitudinally. Available maternal charts were reviewed. RESULTS: Of the total 353 patients, 72 patients (20%) were US-born. Positive hepatitis B envelope antigen (HBeAg) was documented in 208 patients (58%). Three phases of chronic HBV infection were categorized for 329 patients: immune-tolerant 112 (34%), HBeAg-positive immune-active 47 (14%), and inactive carrier 82 (25%). The remaining 88 patients (27%) did not fit into a particular category with 26 of 88 patients meeting the criteria for inactive carrier except for mildly elevated alanine aminotransferase. Age and liver enzyme levels were significantly different between HBeAg-positive and HBeAg-negative groups (P < 0.05). Among 179 patients followed for ≥5 years, the spontaneous seroconversion rate was 38%. In eight patients with linked maternal data, all children completed the HBV vaccine series and seven of eight received hepatitis B immunoglobulin. All mothers were HBeAg-positive with high HBV DNA and had no anti-viral therapy during pregnancy. CONCLUSIONS: Both immune-tolerant and inactive carrier phases were common for chronic HBV infection with a spontaneous seroconversion rate of 38%. All US-born patients were born in the era of implemented universal immune-prophylaxis.

Liver disease and outcomes among COVID-19 hospitalized patients - A systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has been a challenge globally. In severe acute respiratory syndrome (SARS) epidemic 60% of patients had hepatic injury, due to phylogenetic similarities of the viruses it is assumed that COVID-19 is associated with acute liver injury. In this meta-analysis, we aim to study the occurrence and association of liver injury, comorbid liver disease and elevated liver enzymes in COVID-19 confirmed hospitalizations with outcomes. MATERIALS AND METHODS: Data from observational studies describing comorbid chronic liver disease, acute liver injury, elevated aspartate aminotransferase (AST), alanine aminotransferase (ALT) levels and outcomes of COVID-19 hospitalized patients from December 1, 2019, to June 30, 2020 was extracted following PRISMA guidelines. Adverse outcomes were defined as admission to intensive care unit (ICU), oxygen saturation <90%, invasive mechanical ventilation (IMV), severe disease and in-hospital mortality. Odds ratio (OR) and 95% confidence interval (95% CI) were obtained. RESULTS: 24 studies with 12,882 confirmed COVID-19 patients were included. Overall prevalence of CM-CLD was 2.6%, COVID-19-ALI was 26.5%, elevated AST was 41.1% and elevated ALT was 29.1%. CM-CLD had no significant association with poor outcomes (pooled OR: 0.96; 95% CI: 0.71-1.29; p=0.78). COVID-19-ALI (1.68;1.04-2.70; p=0.03), elevated AST (2.98; 2.35-3.77; p<0.00001) and elevated ALT (1.85;1.49-2.29; p<0.00001) were significantly associated with higher odds of poor outcomes. CONCLUSION: Our meta-analysis suggests that acute liver injury and elevated liver enzymes were significantly associated with COVID-19 severity. Future studies should evaluate changing levels of biomarkers amongst liver disease patients to predict poor outcomes of COVID-19 and causes of liver injury during COVID-19 infection.

Outcomes of COVID-19 Complications and their Possibilities as Potential Triggers of Stroke.

INTRODUCTION: There is limited literature on coronavirus disease 2019 (COVID -19) complications such as thromboembolism, cardiac complications etc. as possible trigger for stroke. Hence, we aim to evaluate the prevalence and outcomes of COVID-19 related cardiovascular complications and secondary infection and their possibility as potential triggers for the stroke. METHODS: Data from observational studies describing the complications [acute cardiac injury (ACI), cardiac arrhythmias (CA), disseminated intravascular coagulation (DIC), septic shock, secondary infection] and outcomes of COVID-19 hospitalized patients from December 1, 2019 to June 30, 2020, were extracted following PRISMA guidelines. Adverse outcomes defined as intensive care units, oxygen saturation less than 90%, invasive mechanical ventilation, severe disease, and in-hospital mortality. The odds ratio and 95% confidence interval were obtained, and forest plots were created using random-effects models. A short review of these complications as triggers of stroke was conducted. RESULTS: 16 studies with 3480 confirmed COVID-19 patients, prevalence of ACI [38%vs5.9%], CA [26%vs5.3%], DIC [4%vs0.74%], septic shock [18%vs0.36%], and infection [30%vs12.5%] was higher among patients with poor outcomes. In meta-analysis, ACI [aOR:9.93(95%CI:3.95-25.00], CA [7.52(3.29-17.18)], DIC [7.36(1.24-43.73)], septic shock [30.12(7.56-120.10)], and infection [10.41(4.47-24.27)] had higher odds of adverse outcomes. Patients hospitalized with acute ischemic stroke and intracerebral hemorrhage, had complications like pulmonary embolism, venous thromboembolism, DIC, etc. and had poor outcomes CONCLUSION: The complications like acute cardiac injury, cardiac arrhythmias, DIC, septic shock, and secondary infection had poor outcomes. Patients with stroke were having history of these complications. Long term monitoring is required in such patients to prevent stroke and mitigate adverse outcomes.

Stroke-like migraine attacks after radiation therapy (SMART) syndrome-a case series and review.

INTRODUCTION: Cranial irradiation is used both prophylactically and for the treatment of brain tumors. There are various complications associated with it. The rare complication of stroke-like migraine attacks after radiation therapy (SMART) syndrome usually occurs several years after radiation therapy but is a reversible phenomenon. It usually presents with headaches, seizures, or other focal neurological deficits concerning stroke or recurrence of the underlying disease. OBJECTIVES: We aim to present two cases of SMART syndrome highlighting the typical presentation, imaging findings, and differential diagnosis. We also conducted the literature review since the early recognition of this rare delayed onset complication is crucial, given its self-limited course and to avoid misinterpretations of the cases. CONCLUSION: Our extensive review favors MRI, CT, and prolonged EEG monitoring to rule out other differentials and showed that initiation of corticosteroid therapy and antiepileptic treatment were helpful in the resolution of symptoms and prevent recurrences. Therefore, future studies should be focused on early identification and management guidelines for SMART syndrome.

A single centre experience of treatment outcomes for Helicobacter pylori infection among inner-city children and adolescents.

AIM: This study assessed treatment outcomes of Helicobacter pylori (H pylori) infection among inner-city children. METHODS: This was a retrospective study of patients aged 1-21 years who underwent initial treatment for H pylori infection from 2011 to 2015. We included patients who completed 2 weeks of treatment with documented adequate compliance after H pylori infection was diagnosed. Treatment outcomes were measured based on stool H pylori antigen and/or histology. RESULTS: Of the total 261 patients diagnosed with H pylori, 239 completed the first-line treatment. The regimens used included amoxicillin/clarithromycin/proton pump inhibitor (PPI) in 207/239 patients (86.6%), amoxicillin/metronidazole/PPI in 14/239 patients (5.8%) and other regimens in 18/239 patients (7.5%). H pylori eradication status was tested in 111/207 (53.6%) patients treated with amoxicillin/clarithromycin/PPI, and the eradication was achieved in 84/111(75.7%) patients. The treatment success rates for amoxicillin/metronidazole/PPI and other regimens were 71.4% (5/7) and 63.6% (7/11), respectively. There was no statistical significance of post-treatment stool H pylori antigen results between PPI (n = 31) and no PPI (n = 43) users. CONCLUSION: The study showed an eradication rate of 75.7% with the regimen amoxicillin/clarithromycin/PPI suggesting significant antibiotic resistance in our population. The use of PPI did not influence post-treatment stool H pylori antigen results.

Comparison of chloral hydrate and pentobarbital sedation for pediatric echocardiography.

BACKGROUND: In 2013, outpatient use of chloral hydrate (CH) was limited and other alternatives such as oral pentobarbital (PB) were explored to achieve conscious sedation in young children for transthoracic echocardiography (TTE). We aimed to assess efficacy and safety of the two medications. METHODS: Clinical information, from a computerized database, about children who received sedation with either CH or PB for TTE at our center (2008-2015) was reviewed, and the two groups were compared for sedation effectiveness and complications. RESULTS: Three thousand eight hundred fifty one pediatric patients (median age 8 months) underwent conscious sedation during TTE (mean doses CH 50 mg/kg, PB 4 mg/kg). Demographic characteristics of the two groups were similar. Sedation failure rate (CH 2.4%, PB 2.9%, P = NS), need for supplemental doses (CH 17.9%, PB 16.2%, P = NS), and overall adverse event rate (PB 1.4%, CH 1.9%; P = NS) were similar in the two groups. There were fewer episodes of respiratory depression with PB (0.3% vs 1.6%, P < 0.05). The rate of paradoxical reactions was higher with PB (1% vs 0.03%, P < 0.05). Increasing age predicted the need for supplemental doses and for sedation failure in both groups. Neonates (7.5% vs 0%) and infants (2% vs 0.6%) given CH were more likely to develop adverse reactions. CONCLUSION: Chloral hydrate and PB are equally effective. However, CH is associated with an increased incidence of transient desaturation, while PB is associated with an increased incidence of a paradoxical reaction. Increasing age is predictive of the need for supplemental doses and for failure of sedation in both groups.

Hypocalcemia and Vitamin D Deficiency amongst Migraine Patients: A Nationwide Retrospective Study.

Background and Objectives: Inadequate vitamin D and calcium intake have been linked to many health issues including chronic headaches. Some studies suggested an association between low vitamin D levels and increase the risk of frequent headaches in middle-aged and older men; however, no single study reported the role of these deficiencies in migraine patients. We aimed to investigate the association of hypocalcemia and vitamin D deficiency with migraine hospitalizations. Materials and Methods: A population-based retrospective cross-sectional analysis of the Nationwide Inpatient Sample (NIS) (years 2003-2014) in migraine hospitalizations was performed. The prevalence, demographic characteristics and All Patient Refined Diagnosis Related Groups severity/disability association were compared in patients with hypocalcemia and vitamin D deficiency to those without deficiencies, using ICD-9-CM codes. Weighted analyses using Chi-Square, paired Student's t-test, and Cochran-Armitage trend test were performed. Survey logistic regression was performed to find an association between deficiencies and migraine hospitalizations and deficiency induced disability amongst migraineurs. Results: Between years 2003 and 2014, of the total 446,446 migraine hospitalizations, 1226 (0.27%) and 2582 (0.58%) presented with hypocalcemia and vitamin D deficiency, respectively. In multivariable analysis, hypocalcemia [Odds Ratio (OR): 6.19; Confidence Interval (CI): 4.40-8.70; p < 0.0001] and vitamin D deficiency (OR: 3.12; CI: 2.38-4.08; p < 0.0001) were associated with markedly elevated odds of major/extreme loss of function. There was higher prevalence (3.0% vs. 1.5% vs. 1.6%; p < 0.0001) and higher odds of migraine among vitamin D deficiency (OR: 1.97; CI: 1.89-2.05; p < 0.0001) patients in comparison to patients with hypocalcemia (OR: 1.11; CI: 1.03-1.20; p = 0.0061) and no-deficiency, respectively. Conclusions: In this study, we demonstrated a significant association between hypocalcemia and vitamin D deficiency with migraine attacks and deficiency induced loss of function among migraineurs. Early preventive measures may reduce the disability in migraineurs.

The Lipid Paradox Among Acute Ischemic Stroke Patients-A Retrospective Study of Outcomes and Complications.

BACKGROUND AND OBJECTIVES: The Studies have suggested hypercholesterolemia is a risk factor for cerebrovascular disease. However, few of the studies with a small number of patients had tested the effect of hypercholesterolemia on the outcomes and complications among acute ischemic stroke (AIS) patients. We hypothesized that lipid disorders (LDs), though risk factors for AIS, were associated with better outcomes and fewer post-stroke complications. MATERIALS AND METHOD: We performed a retrospective analysis of the Nationwide Inpatient Sample (years 2003-2014) in adult hospitalizations for AIS to determine the outcomes and complications associated with LDs, using ICD-9-CM codes. In 2014, we also aimed to estimate adjusted odds of AIS in patients with LDs compared to patients without LDs. The multivariable survey logistic regression models, weighted to account for sampling strategy, were fitted to evaluate relationship of LDs with AIS among 2014 hospitalizations, and outcomes and complications amongst AIS patients from2003-2014. RESULTS AND CONCLUSIONS: In 2014, there were 28,212,820 (2.02% AIS and 5.50% LDs) hospitalizations. LDs patients had higher prevalence and odds of having AIS compared with non-LDs. Between 2003-2014, of the total 4,224,924 AIS hospitalizations, 451,645 (10.69%) had LDs. Patients with LDs had lower percentages and odds of mortality, risk of death, major/extreme disability, discharge to nursing facility, and complications including epilepsy, stroke-associated pneumonia, GI-bleeding and hemorrhagic-transformation compared to non-LDs. Although LDs are risk factors for AIS, concurrent LDs in AIS is not only associated with lower mortality and disability but also lower post-stroke complications and higher chance of discharge to home.

Diagnostic value of intraoperative fine-needle aspiration cytologic diagnosis versus frozen section-based histopathologic diagnosis in thoracic malignancies: A single institution's experience.

BACKGROUND: Primary lung cancer is the leading cause of cancer death in the United States. Most lung cancers are diagnosed in an outpatient setting, but a subset requires intraoperative diagnosis. Two intraoperative diagnostic methods are available, frozen section (FS) and fine needle aspiration (FNA) cytology. This study compares intraoperative FNA cytology and FS based diagnosis in thoracic malignancies within the same clinical practice. METHODS: Pathology reports from thoracic intraoperative FNA cytology or FS (January 2017-December 2019) were reviewed. Resection diagnosis was the gold standard. If unavailable, concurrent biopsy and final FNA cytology diagnosis were the gold standard. RESULTS: Of 300 FNA specimens (155 patients), 142 (47%) cases were benign, and 158 (53%) were malignant. Adenocarcinoma was the most common malignant diagnosis (40%), followed by squamous cell carcinoma (26%), neuroendocrine tumors (18%), and other (16%). Intraoperative FNA yielded 88% sensitivity, 99% specificity, and 92% accuracy (p < .001). Of 298 FS specimens (252 patients), 215 (72%) cases were malignant and 83 (28%) were benign. Adenocarcinomas was the most common malignant diagnosis (48%), followed by squamous cell carcinoma (25%), metastatic carcinomas (13%), and other (14%). FS yielded 97% sensitivity, 99% specificity, and 97% accuracy (p < .001). CONCLUSION: Our findings confirm FS is the gold standard for intraoperative diagnosis. FNA cytology may be useful as a non-invasive, inexpensive initial diagnostic tool intraoperatively, given the similar specificity (99% FNA, 99% FS) and accuracy (92% FNA, 97% FS). Negative FNA could be followed by the costlier and invasive FS. We encourage surgeons to utilize intraoperative FNA first.

Effectiveness of Repetitive Transcranial Magnetic Stimulation in Depression, Schizophrenia, and Obsessive-Compulsive Disorder: An Umbrella Meta-Analysis.

Objective: To analyze the safety and efficacy of repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder, schizophrenia, and obsessive-compulsive disorder (OCD) via umbrella meta-analysis.Data Sources: Meta-analysis studies were searched in PubMed from inception to May 2021 using the keywords anxiety, depression, ADHD, schizophrenia, mood disorder, OCD, psychiatric disorders, GAD, bipolar disorders, ASD, PTSD, transcranial magnetic stimulation, transcranial, magnetic, stimulation. PRISMA guidelines were followed.Study Selection: Abstracts and full-length articles were reviewed for meta-analysis studies with data on the safety and efficacy of rTMS and sham and were collected for quantitative analysis. The full texts of all identified studies were independently screened and assessed to determine eligibility. Any disagreement was resolved through consensus.Data Extraction: The descriptive variables extracted included the author names, study year, sample size, studies included in the meta-analysis, study period, and type of intervention.Results: 28 meta-analyses were included; 13 were on treatment-resistant depression, 9 on schizophrenia, and 6 on OCD. In treatment-resistant depression, the rTMS group had higher odds of response compared to sham (odds ratio [OR] = 3.27; 95% CI, 2.76-3.87; P < .00001) and higher odds of remission (secondary outcome) (OR = 2.83; 95% CI, 2.33-3.45; P < .00001). rTMS was superior to sham in the reduction of negative symptoms of schizophrenia (mean difference [MD]: 0.47; 95% CI, 0.23-0.7; P < .0001). However, no significant difference was found between the effects of rTMS and sham on auditory hallucinations (MD: 0.24; 95% CI, 0.26-0.74; P = .35), which resulted in 94% heterogeneity. TMS was better than sham in reducing the severity of OCD symptoms (MD: 0.81; 95% CI, 0.53-1.10; P < .00001).Conclusions: The effectiveness of rTMS for symptom reduction in various psychiatric disorders is associated with differences in neuropathology, disease-specific target site, and frequency of rTMS.Prim Care Companion CNS Disord 2023;25(5):22r03423.

Automated detection of immune effector cell-associated neurotoxicity syndrome via quantitative EEG.

OBJECTIVE: To develop an automated, physiologic metric of immune effector cell-associated neurotoxicity syndrome among patients undergoing chimeric antigen receptor-T cell therapy. METHODS: We conducted a retrospective observational cohort study from 2016 to 2020 at two tertiary care centers among patients receiving chimeric antigen receptor-T cell therapy with a CD19 or B-cell maturation antigen ligand. We determined the daily neurotoxicity grade for each patient during EEG monitoring via chart review and extracted clinical variables and outcomes from the electronic health records. Using quantitative EEG features, we developed a machine learning model to detect the presence and severity of neurotoxicity, known as the EEG immune effector cell-associated neurotoxicity syndrome score. RESULTS: The EEG immune effector cell-associated neurotoxicity syndrome score significantly correlated with the grade of neurotoxicity with a median Spearman's R2 of 0.69 (95% CI of 0.59-0.77). The mean area under receiving operator curve was greater than 0.85 for each binary discrimination level. The score also showed significant correlations with maximum ferritin (R2 0.24, p = 0.008), minimum platelets (R2 -0.29, p = 0.001), and dexamethasone usage (R2 0.42, p < 0.0001). The score significantly correlated with duration of neurotoxicity (R2 0.31, p < 0.0001). INTERPRETATION: The EEG immune effector cell-associated neurotoxicity syndrome score possesses high criterion, construct, and predictive validity, which substantiates its use as a physiologic method to detect the presence and severity of neurotoxicity among patients undergoing chimeric antigen receptor T-cell therapy.

Mental health disparities amongst sexual-minority adolescents of the US - A national survey study of YRBSS-CDC.

OBJECTIVE: We aimed to evaluate the prevalence and trend of identifying as a sexual minority among the American adolescent population. Additionally, we aimed to evaluate the prevalence and odds of substance abuse, hopelessness, and suicidality among the sexual minority adolescents compared to their heterosexual peers. METHODS: We performed a retrospective cross-sectional study using Youth Risk Behavior Surveillance System (YRBSS) data from 2015 to 2019. YRBSS divides "Sexual identity" into three groups: heterosexuals, sexual minorities (gay or lesbian or bisexual), and unsure. We identified "hopelessness and suicidality" using the survey questions exploring if participants felt sad or hopeless for >2 weeks, considered suicide, made a suicide plan, and attempted suicide requiring medical care. Univariate and multivariable survey logistic regression analyses were performed to establish an association between hopelessness, suicidality, substance abuse, and identifying as a sexual minority. RESULTS: Out of 41,377 adolescents, 4055 (9.8%) identified as a sexual minority. An increasing percentage of adolescents identified themselves as a sexual minority between 2015 to 2019 (8% to 11.2%) (pTrend<0.0001). The sexual minority had a higher prevalence of feeling sad and hopeless (63.4 vs. 28.6%), considering suicide (46 vs. 14.2%), planning suicide (38.9 vs. 11.5%), attempting suicide, and having injurious suicide attempts compared to heterosexuals. (p<0.0001) Amongst sexual minorities, the prevalence of substance abuse was higher compared to their heterosexual peers, which includes cigarettes (15 vs 7.8%), e-cigarette (27.2 vs 23.2%), inhalants (14.1 vs 5.3%), cocaine (8.4 vs 3.9%), marijuana (31.2 vs 20.2%), alcohol (36.9 vs 30.3%), steroids (6.4 vs 2.2%), heroin (4.4 vs 1.2%), and injectable drugs (4.0 vs 1.1%) (p<0.0001). In regression analysis, the sexual minority had higher odds of substance abuse, feeling sad and hopeless (aOR:4.6; 95%CI:4.0-5.2; p<0.0001), considering suicide (3.2; 2.8-3.7; p<0.0001), planning suicide (2.0; 1.7-2.3; p<0.0001) compared to heterosexual. CONCLUSION: Sexual minorities not only have higher prevalence and odds of hopelessness and suicidality but also have higher prevalence and odds of substance abuse like cigarettes, marijuana, cocaine, heroin, inhalants, and steroids. Hence, early identification, risk stratification, and interventions to reduce mental health disparities are needed.

Association of Smoking and E-Cigarette in Chronic Liver Disease: An NHANES Study.

Background: There is an increased trend of e-cigarette but the toxic effects of e-cigarette metabolites are not widely studied especially in liver disease. Hence, we aimed to evaluate the prevalence and patterns of recent e-cigarette use in a nationally representative sample of US adults and adolescents and its association amongst respondents with liver disease. Methods: We conducted a retrospective cross-sectional study using National Health and Nutrition Examination Survey (NHANES) database from 2015 to 2018. The self-reported NHANES questionnaire was used to assess liver disease (MCQ160L, MCQ170L and MCQ 510 (a-e)), e-cigarette use (SMQ900) and traditional smoking status (SMQ020 or SMQ040). We conducted univariate analysis and multivariable logistic regression models to predict the association of e-cigarette use, traditional smoking and dual smoking amongst the population with liver disease. Results: Out of total 178,300 respondents, 7,756 (4.35%) were e-cigarette users, 48,625 (27.27%) traditional smoking, 23,444 (13.15%) dual smoking and 98,475 (55.23%) non-smokers. Females had a higher frequency of e-cigarette use (49.3%) compared to dual (43%) and traditional smoking (40.8%) (P < 0.0001). Respondents with a past history of any liver disease have lower frequency of e-cigarette use compared to dual and traditional smoking, respectively (2.4% vs. 6.4% vs. 7.2%; P < 0.0001). In multivariate logistic regression models, we found that e-cigarette users (odds ratio (OR): 1.06; 95% confidence interval (CI): 1.05 - 1.06; P < 0.0001) and dual smoking (OR: 1.50; 95% CI: 1.50 - 1.51; P < 0.0001) were associated with higher odds of having history of liver disease compared to non-smokers. Conclusion: Our study found that despite the low frequency of e-cigarette use in respondents with liver disease, there was higher odds of e-cigarette use amongst patients with liver disease. This warrants the need for more future prospective studies to evaluate the long-term effects and precise mechanisms of e-cigarette toxicants on the liver.

Kidney disease and COVID-19 disease severity-systematic review and meta-analysis.

We aimed to identify prevalence and association of comorbid chronic kidney disease (CKD), acute kidney injury (AKI) and utilization prevalence of continuous renal replacement therapy (CRRT) in COVID-19-hospitalized patients as a function of severity status. With the ongoing struggle across the globe to combat COVID-19 disease, published literature has described the role of kidney disease in COVID-19 patients based on single/multicenter experiences across the globe. We extracted data from observational studies describing comorbid CKD, AKI and CRRT and outcomes and severity of COVID-19-hospitalized patients from December 1, 2019-August 20, 2020 following PRISMA guidelines. Severity of COVID-19 includes intensive care unit admission, oxygen saturation < 90%, invasive mechanical ventilation utilization, in-hospital admission and mortality. Meta-analysis was performed using a random-effects model to calculate pooled estimates, and forest plots were created. In total, 29 studies with 15,017 confirmed COVID-19 patients were included. The overall prevalence of AKI was 11.6% [(430/3693)], comorbid CKD 9.7% [(1342/13,728)] and CRRT 2.58% [(102/3946)] in our meta-analysis. We also found higher odds of comorbid CKD (pooled OR: 1.70; 95%CI: 1.21-2.40; p = 0.002), AKI (8.28; 4.42-15.52; p < 0.00001) and utilization of CRRT (16.90; 9.00-31.74; p < 0.00001) in patients with severe COVID-19 disease. Conclusion Our meta-analysis suggests that comorbid CKD, AKI and utilization of CRRT were significantly associated with COVID-19 disease severity. Clinicians should focus on early triaging of COVID-19 patients with comorbid CKD and at risk for AKI to prevent complication and mortality.

Diagnostic Accuracy of Elastography and Liver Disease: A Meta-Analysis.

Background: Ultrasound-based transient elastography (TE) is a non-invasive alternative to liver biopsy for the staging of hepatic fibrosis due to various chronic liver diseases. This meta-analysis aims to assess the diagnostic accuracy of TE for detecting liver cirrhosis (F4) and severe fibrosis (F3) in patients with chronic liver diseases, in comparison to the gold standard liver biopsy. Methods: A systematic search was performed using PubMed search engine following Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines from inception to May 2021. The meta-analysis studies evaluating the diagnostic accuracy of TE for severe fibrosis and cirrhosis were identified. We conducted a meta-meta-analysis to generate pooled estimates of the sensitivity, specificity, and diagnostic odds ratios (ORs) for F3 and F4 fibrosis stage. Results: We included five studies with a total of 124 sub-studies and 20,341 patients in our analysis. Three studies have reported the diagnostic accuracy of TE in detecting F3/severe fibrosis stage and found 81.9% pooled sensitivity (95% confidence interval (CI): 79.9-83.7%; P < 0.001) (I2 = 0%), 84.7% pooled specificity (95% CI: 81.3-87.6%) (I2 = 81%; P = 0.02). All five studies reported the diagnostic accuracy of TE in detecting F4/liver cirrhosis stage. We found 84.8% pooled sensitivity (95% CI: 81.4-87.7%) (I2 = 86.4%; P < 0.001), 87.5% pooled specificity (95% CI: 85.4-89.3%) (I2 = 90%; P < 0.001) and pooled diagnostic OR (41.8; 95% CI: 3.9 - 56.5) (I2 = 87%; P < 0.001). Conclusions: Ultrasound-based TE has excellent diagnostic accuracy for identifying cirrhosis and liver fibrosis stages 3. Future studies should focus on estimating the diagnostic accuracy of other fibrosis stages in chronic liver disease patients. This will eventually decrease the risk associated with invasive liver biopsy.

Forecasting immune effector cell-associated neurotoxicity syndrome after chimeric antigen receptor t-cell therapy.

BACKGROUND: Immune effector cell-associated neurotoxicity syndrome (ICANS) is a clinical and neuropsychiatric syndrome that can occur days to weeks following administration chimeric antigen receptor (CAR) T-cell therapy. Manifestations of ICANS range from encephalopathy and aphasia to cerebral edema and death. Because the onset and time course of ICANS is currently unpredictable, prolonged hospitalization for close monitoring following CAR T-cell infusion is a frequent standard of care. METHODS: This study was conducted at Brigham and Women's Hospital from April 2015 to February 2020. A cohort of 199 hospitalized patients treated with CAR T-cell therapy was used to develop a combined hidden Markov model and lasso-penalized logistic regression model to forecast the course of ICANS. Model development was done using leave-one-patient-out cross validation. RESULTS: Among the 199 patients included in the analysis 133 were male (66.8%), and the mean (SD) age was 59.5 (11.8) years. 97 patients (48.7%) developed ICANS, of which 59 (29.6%) experienced severe grades 3-4 ICANS. Median time of ICANS onset was day 9. Selected clinical predictors included maximum daily temperature, C reactive protein, IL-6, and procalcitonin. The model correctly predicted which patients developed ICANS and severe ICANS, respectively, with area under the curve of 96.7% and 93.2% when predicting 5 days ahead, and area under the curve of 93.2% and 80.6% when predicting the entire future risk trajectory looking forward from day 5. Forecasting performance was also evaluated over time horizons ranging from 1 to 7 days, using metrics of forecast bias, mean absolute deviation, and weighted average percentage error. CONCLUSION: The forecasting model accurately predicts risk of ICANS following CAR T-cell infusion and the time course ICANS follows once it has begun.Cite Now.

EEG-based grading of immune effector cell-associated neurotoxicity syndrome.

CAR-T cell therapy is an effective cancer therapy for multiple refractory/relapsed hematologic malignancies but is associated with substantial toxicity, including Immune Effector Cell Associated Neurotoxicity Syndrome (ICANS). Improved detection and assessment of ICANS could improve management and allow greater utilization of CAR-T cell therapy, however, an objective, specific biomarker has not been identified. We hypothesized that the severity of ICANS can be quantified based on patterns of abnormal brain activity seen in electroencephalography (EEG) signals. We conducted a retrospective observational study of 120 CAR-T cell therapy patients who had received EEG monitoring. We determined a daily ICANS grade for each patient through chart review. We used visually assessed EEG features and machine learning techniques to develop the Visual EEG-Immune Effector Cell Associated Neurotoxicity Syndrome (VE-ICANS) score and assessed the association between VE-ICANS and ICANS. We also used it to determine the significance and relative importance of the EEG features. We developed the Visual EEG-ICANS (VE-ICANS) grading scale, a grading scale with a physiological basis that has a strong correlation to ICANS severity (R = 0.58 [0.47-0.66]) and excellent discrimination measured via area under the receiver operator curve (AUC = 0.91 for ICANS ≥ 2). This scale shows promise as a biomarker for ICANS which could help to improve clinical care through greater accuracy in assessing ICANS severity.
