Exploring Factors Influencing Cervical Cancer Prevention Behaviors: Unveiling Perspectives of Conservative Muslim American Women in Virginia.

Understanding the complexities surrounding cervical cancer prevention methods and hesitancy among conservative Muslim American women is crucial in addressing health disparities. This qualitative study aimed to delve into the religious, behavioral, and socio-cultural factors influencing Muslim women's decisions regarding cervical cancer screening (CC-S) and HPV vaccination (HPV-V) in Virginia, USA. Through interviews with 10 Muslim women residing in Virginia, qualitative data were collected as part of a mixed-method cross-sectional study conducted between August and September 2021. Findings revealed that participants had limited knowledge about cervical cancer, CC-S, and HPV-V, with notable themes emerging, such as cultural influences, misconceptions, language barriers, and challenges posed by the intricate US healthcare system. Future research should focus on exploring these barriers to mitigate the impact of cervical cancer within the Muslim population.

Rapid induction onto extended-release injectable buprenorphine following opioid overdose: A case series.

Background: Buprenorphine treatment has been associated with reduced non-prescribed opioid use and opioid related overdose (OD). We evaluated initial outcomes of rapid induction onto extended-release injectable buprenorphine (BUP-XR) within 7 days of emergency department presentation for unintentional OD. Methods: Between February 2019-February 2021, N = 19 patients with opioid use disorder received buprenorphine/naloxone (4/1 mg), followed by BUP-XR (300 mg) at induction and continued BUP-XR outpatient for 6 months. Primary outcomes included adverse events, repeat OD, and death. Results: For patients who received at least one dose of BUP-XR, there were no treatment related serious adverse events or symptoms of precipitated withdrawal. In addition, there were no repeat visits for ODs or deaths within 6 months of the initial OD. Discussion: These preliminary findings support the need for larger controlled clinical trials to examine the safety and efficacy of rapid induction of BUP-XR in patients with opioid use disorder at high risk of opioid OD. Rapid induction onto long-lasting injectable buprenorphine may be a promising and protective treatment approach in the future.

QT Prolongation and In-Hospital Ventricular Arrhythmic Complications in Patients With Apical Ballooning Takotsubo Syndrome.

BACKGROUND: Takotsubo syndrome is associated with life threatening arrhythmias, and the apical ballooning pattern is characterized by a peculiar QT prolongation and particularly high-risk of arrhythmias. OBJECTIVES: The aim of the study was to determine the association of QT interval on electrocardiogram for ventricular arrhythmic complications in patients with apical ballooning Takotsubo syndrome in a diverse population at a large urban hospital in the U.S. METHODS: We reviewed 105 cases of apical ballooning Takotsubo syndrome in patients admitted between 2011 and 2017. Two cardiologists reviewed the electrocardiograms to measure QT interval, adjusted for rate using the Fridericia formula (QTCF), and ventricular arrhythmic complications during the hospitalization. Data are reported as median and interquartile range or number and percentage. RESULTS: Of the 105 patients, 86 (82%) were female, and 34 (32%) were self-reported Black or African American. The mean age was 65 years (range: 58-72 years). Left ventricular ejection fraction was 25% (range: 25%-35%). Heart rate was 101 beats/min (range: 83-121 beats/min). Ten (11%) patients experienced a ventricular arrhythmic complication and had significantly longer QTCF (470 [range: 422-543] milliseconds) than did those without complications (417 [range: 383-456] milliseconds, P = 0.031). The area under the curve for QTCF was 0.708 (95% CI: 0.536-0.880; P = 0.031). Twenty-eight (27%) patients had a QTCF ≥460 milliseconds and significantly more arrhythmic complications (21% vs 5%, odds ratio 4.997 [95% CI: 1.288-19.237], P = 0.021). QTCF was an independent predictor of ventricular arrhythmias: odds ratio 1.090 for each 10-millisecond increase in QTCF (95% CI: 1.004-1.183; P = 0.040, corrected for sex). CONCLUSIONS: In a diverse population of patients with apical ballooning Takotsubo syndrome admitted to a large urban hospital in the United States, QTCF at admission ≥460 milliseconds identifies patients at high risk for in-hospital arrhythmic complications. Further studies are needed to determine strategies aimed at shortening QT interval to potentially prevent life-threatening arrhythmic events.

Nonalcoholic fatty liver disease is specifically related to the risk of hepatocellular cancer but not extrahepatic malignancies.

Objective: We performed a matched cohort study among individuals with and without nonalcoholic fatty liver disease (NAFLD) to determine: 1) the incidence of cancers (extrahepatic and liver) and their spectrum and 2) if NAFLD increases the risk of extrahepatic cancers. Methods: The NAFLD and non-NAFLD (control) cohorts were identified from electronic medical records via International Classification of Diseases (ICD) codes from a single center and followed from 2010 to 2019. Cohorts were matched 1:2 for age, sex, race, body mass index (BMI), and type 2 diabetes. Results: A total of 1,412 subjects were included in the analyses. There were 477 individuals with NAFLD and 935 controls (median age, 52 years; women, 54%; white vs. black: 59% vs. 38%; median BMI, 30.4 kg/m2; type 2 diabetes, 34%). The cancer incidence (per 100,000 person-years) was 535 vs. 1,513 (NAFLD vs. control). Liver cancer incidence (per 100,000 person-years) was 89 in the NAFLD group vs. 0 in the control group, whereas the incidence of malignancy was higher across other types of cancer in the control group vs. in the NAFLD group. Conclusions: The overall extrahepatic cancer risk in NAFLD is not increased above and beyond the risk from background risk factors such as age, race, sex, BMI, and type 2 diabetes.

Results of ultra-fresh osteochondral allograft transplantation for large cartilage defects in the knee joint.

OBJECTIVES: This study aims to investigate whether ultra-fresh osteochondral allograft (OCA) transplantation was a good therapeutic alternative for the treatment of otherwise challenging, massive osteochondral defects in the knee joint. PATIENTS AND METHODS: Between April 2011 and July 2022, a total of 16 ultra-fresh knee transplantations (9 males, 7 females; median age: 30.2 years; range, 14 to 62 years) having large osteochondral defects on femoral condyles were included. The operations were performed by two surgeons. The condition of the patients were evaluated based on regular follow-up physical examinations, imaging studies and by recording and evaluating clinical scores (modified Cincinnati scores, and 2000 International Knee Documentation Committee [IKDC] scores). RESULTS: The median follow-up was 65±48 (range, 6 months to 12 years). At two years after transplantation, there was a significant improvement in the modified Cincinnati scores (preoperative score of 35.75 increased to 83.75; p<0.001) and also to the IKDC scores (preoperative score of 28.7 increased to 76.3; p<0.001). One patient developed an early septic complication, and another three patients underwent reoperation after the OCA transplantations for non-septic reasons. CONCLUSION: Ultra-fresh OCA transplantation is a good therapeutic alternative for the treatment of otherwise challenging, massive osteochondral defects in the knee joint. Such a shortening of the transplantation time and its positive effect on the better long-term survival of transplanted chondrocytes has not yet been proven; however, the minimizing of transplantation time may create the conditions necessary for successful OCA transplantations many years after the implantation.

Development and Validation of a Two-Step Predictive Risk Stratification Model for Coronavirus Disease 2019 In-hospital Mortality: A Multicenter Retrospective Cohort Study.

Objectives: An accurate prognostic score to predict mortality for adults with COVID-19 infection is needed to understand who would benefit most from hospitalizations and more intensive support and care. We aimed to develop and validate a two-step score system for patient triage, and to identify patients at a relatively low level of mortality risk using easy-to-collect individual information. Design: Multicenter retrospective observational cohort study. Setting: Four health centers from Virginia Commonwealth University, Georgetown University, the University of Florida, and the University of California, Los Angeles. Patients: Coronavirus Disease 2019-confirmed and hospitalized adult patients. Measurements and Main Results: We included 1,673 participants from Virginia Commonwealth University (VCU) as the derivation cohort. Risk factors for in-hospital death were identified using a multivariable logistic model with variable selection procedures after repeated missing data imputation. A two-step risk score was developed to identify patients at lower, moderate, and higher mortality risk. The first step selected increasing age, more than one pre-existing comorbidities, heart rate >100 beats/min, respiratory rate ≥30 breaths/min, and SpO2 <93% into the predictive model. Besides age and SpO2, the second step used blood urea nitrogen, absolute neutrophil count, C-reactive protein, platelet count, and neutrophil-to-lymphocyte ratio as predictors. C-statistics reflected very good discrimination with internal validation at VCU (0.83, 95% CI 0.79-0.88) and external validation at the other three health systems (range, 0.79-0.85). A one-step model was also derived for comparison. Overall, the two-step risk score had better performance than the one-step score. Conclusions: The two-step scoring system used widely available, point-of-care data for triage of COVID-19 patients and is a potentially time- and cost-saving tool in practice.

Arrhythmic Recurrence and Outcomes in Patients Hospitalized With First Episode of Electrical Storm.

Electrical storm (ES) is a life-threatening condition that may lead to recurrent arrhythmias, need for ventricular mechanical support, and death. The study aimed to assess the burden of arrhythmia recurrence and in-hospital outcomes of patients admitted for ES in a large urban hospital. We performed a retrospective analysis of patients admitted with ventricular arrhythmias from January 2018 to June 2021 and identified 61 patients with ES, defined as 3 or more episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) within 24 hours. We reviewed the in-hospital outcomes and compared outcomes between patients who had no recurrence of VT/VF after the first 24 hours (34 [56%]), those with recurrence of 1 or 2 episodes of VT/VF within a 24-hour period (15 [24%]), and patients with 3 or more recurrent VT/VF events consistent with recurrent ES after the first 24 hours (12 [20%]). Patients with recurrent ES had significantly higher in-hospital mortality as compared with those with recurrent VT/VF not meeting criteria for ES or no recurrences of VT/VF (3 [25%] vs 0 [0%] vs 0 [0%]; p = 0.002). Moreover, patients with recurrent ES also had higher rates of the combined end points of ventricular mechanical support and death (7 [58%] vs 1 [6%] vs 1 [3%], p <0.001), invasive mechanical ventilation and death (10 [83%] vs 2 [13%] vs 2 [6%], p <0.001), catheter ablation or death (12 [100%] vs 7 [47%] vs 12 [35%], p <0.001) and heart transplantation and death (3 [25%] vs 2 [13%] vs 0 [0%], p = 0.018). In conclusion, patients admitted with ES have a high risk of in-hospital recurrence, associated with extremely poor outcomes.

Eligibility Criteria Perpetuate Disparities in Enrollment and Participation of Black Patients in Pancreatic Cancer Clinical Trials.

PURPOSE: Clinical trials determine safety and efficacy of cancer therapeutics and establish standards of care. Minority patient participation in cancer clinical trials is dismal. We aimed to determine the impact of eligibility criteria on disparities in pancreatic ductal adenocarcinoma (PDAC) clinical trial candidacy. METHODS: Traditional PDAC trial eligibility criteria were obtained from ClinicalTrials.gov. Patients with PDAC who sought care at Virginia Commonwealth University Health from 2010 to 2019 were included. Clinical data were obtained from billing codes and discrete values in the electronic medical record. Eligibility criteria differences between racial groups were determined using chi-squared tests and unconditional maximum likelihood-based odds ratios. RESULTS: Among 676 patients, most identified as Black or White race (42.5% and 51.6%, respectively). Using traditional criteria, Black patients were more likely to be ineligible for participation compared with White patients (42.4% v 33.2%, P = .023) secondary to hypoalbuminemia (14.1% v 7.9%, P = .023), HIV (3.1% v 0.3%, P = .010), hepatitis B (1.7% v 0%, P = .043), and hepatitis C (9.1% v 3.4%, P = .005). Black patients were also numerically more likely to be ineligible because of renal dysfunction, recent coronary stenting, and uncontrolled diabetes mellitus. Prior cancer treatment excluded fewer Black than White patients (9.1% v 14.0%, P = .072), most attributable to lower rates of neoadjuvant chemotherapy received. Strategic eligibility criteria revisions could equalize ineligibility rates between Black and White patients (26.8% v 24.8%, P = .581). CONCLUSION: Traditional eligibility criteria differentially exclude Black patients from participating in PDAC clinical trials. These criteria perpetuate disparities, limit generalizability, and are often not medically justifiable. Revised criteria may improve participant diversity, without compromising safety or study results.

Pericarditis Recurrence After Initial Uncomplicated Clinical Course.

Acute pericarditis is an inflammatory disease associated with a non-negligible risk of acute complications and future recurrence. However, the exact incidence of pericarditis recurrence in patients with a first uncomplicated clinical course is unknown. We sought to evaluate the incidence and clinical predictors of recurrence after a first episode of acute uncomplicated pericarditis in a large urban hospital in the United States. We conducted a retrospective review, through electronic health records, to complete a database that includes patients admitted with a first episode of acute pericarditis and selected only those with an uncomplicated course (without in-hospital death, large pericardial effusion [>20 mm] or tamponade, constriction, or incessant pericarditis) at the VCU Medical Center (Richmond, Virginia) from 2009 to 2018. A total of 240 patients met acute pericarditis criteria: of the 240 patients, 164 patients (68%) had an uncomplicated course (median age [interquartile range] in years: 50 [32 to 62], 43% females). The median follow-up time was 186 (19 to 467) days. Pericarditis was idiopathic in 84 patients (51%). Fifteen patients (9%) had at least 1 episode of recurrent pericarditis. Compared with those without recurrence, patients with recurrent pericarditis were younger (37 [25 to 59] vs 51 [34 to 62] years, p = 0.034), had a higher prevalence of subacute/delayed presentation (2 [13%] vs 1 [1%], p = 0.023), and less frequently received colchicine (6 [40%] vs 100 [67%], p = 0.036). At multivariate logistic regression analysis, subacute presentation and younger age remained predictors of recurrence at follow-up. In conclusion, 9% of patients with acute pericarditis experienced a recurrence over a 6-month median follow-up despite an initial uncomplicated course. Younger age and subacute presentation were associated with a significantly increased risk of recurrence.

Health disparities and equity in the era of COVID-19.

Over the last year, COVID-19 has emerged as a highly transmissible and lethal infection. As we address this global pandemic, its disproportionate impact on Black, Indigenous, and Latinx communities has served to further magnify the health inequities in access and treatment that persist in our communities. These sobering realities should serve as the impetus for reexamination of the root causes of inequities in our health system. An increased commitment to strategic partnerships between academic and nonacademic health systems, industry, local communities, and policy-makers may serve as the foundation. Here, we examine the impact of the recent COVID-19 pandemic on health care inequities and propose a strategic roadmap for integration of clinical and translational research into our understanding of health inequities.

A comparison of SanatMetal Sanat Swing and Zimmer NexGen® total knee implants: 10-year postoperative follow-up results.

OBJECTIVES: In this study, we present our 10-year postoperative follow-up results of Sanat Swing® and NexGen® total knee implants. PATIENTS AND METHODS: A total of 189 patients (93 males, 96 females; mean age: 68 years; range, 48 to 86 years) who underwent total knee replacement between January 2008 and September 2010 were retrospectively analyzed. A total of 105 patients (Group A) were implanted a cemented Sanat Swing knee prosthesis and 84 patients (Group B) were implanted a cemented NexGen knee prosthesis. Operation time, range of motion (ROM), pain level, Knee Society Score (KSS), distance of painless walking, and the ability to climb stairs were evaluated between the groups. RESULTS: The mean follow-up was 10.8 (range, 9.8 to 12.3) years. No significant difference was observed in the survival of the prostheses, ROM, pain level, KSS, walking distance, and in the ability to climb stairs between the two groups at 10 years. With an experienced team, the operation time was about 4 to 5 min shorter in the Sanat Swing implantation group. In selected cases, Sanat Swing was superior to the NexGen system; however, there was no statistically significant difference. Complication rates were also low and comparable between both groups. CONCLUSION: Based on the 10 years of follow-up evaluation, Sanat Swing total knee replacement system seems to yield comparable clinical results with the NexGen. Experiences with the operative technique and comparative evaluation, the Sanat Swing system is a safe and reliable alternative for total knee replacement, providing a user-friendly operative technique and shorter operation time.

Clinical features and outcomes between African American and Caucasian patients with Takotsubo Syndrome.

BACKGROUND: Takotsubo syndrome (TS) is an acute, reversible form of heart failure, often mimicking an acute coronary syndrome (ACS). Data regarding racial differences in TS are inconsistent. The aim is to assess clinical features associated with unfavorable in-hospital outcomes between African American (AA) and Caucasian (CAU) patients. METHODS: A retrospective electronic health record query identified 44 AA patients and 110 CAU patients with a diagnosis of TS. Our primary outcome was a composite of death, stroke, and cardiogenic shock during hospitalization. Variables associated with an increased risk of the primary composite outcomes were included in a logistic regression model. RESULTS: Compared to CAU patients, AA patients were a more comorbid population, and presented a higher prevalence of history of illicit drug use (27.3% vs. 13.6% P=0.044). There were no significant differences regarding in-hospital complication rates between AA and CAU patients. In the logistic regression model, infection was associated with greater risk of developing the primary outcome in AA patients (OR=7.26 [95% CI 1.22-43.17], P=0.029), whereas angina was a protective factor (OR=0.11 [95% CI 0.02-0.65], P=0.015). In CAU patients, severely depressed ejection fraction and worse peak creatinine during hospitalization increased risk of developing the primary outcome (OR=5.88 95% CI [2.01-17.17], P<0.001 and OR=1.64 [95% CI 1.15-2.58], P=0.031, respectively). Meanwhile, emotional stressors were protective (OR=0.16 [95% CI 0.03-0.88], P=0.004). CONCLUSIONS: Despite experiencing the same rate of in-hospital complications, the clinical profiles of AA patients are distinct from CAU patients admitted for TS, and clinical variables correlated with worse in-hospital outcomes also differ by race.

Muslim Women and Disparities in Cancer Diagnosis: A Retrospective Study.

Muslim women often find their religious customs at odds with their healthcare needs, such as regular gynecological check-ups and cervical cancer screenings, especially before marriage. Religious beliefs may also affect beliefs about gender roles, illness, and death, affecting seeking healthcare services. This retrospective study explored the differences in care-seeking related to cancer between Muslim women and the general female population at the Virginia Commonwealth University in the United States between 2010 and 2019. There were major differences in insurance status between the two cohorts. Muslim women were less likely to have government-sponsored health insurance and were much more likely to be uninsured than non-Muslim women. We also found that preventable female cancers were more prevalent among Muslim women than among non-Muslim women and was also diagnosed at more advanced stages.

Radiosynoviorthesis in the treatment of posttraumatic joint bleedings of hemophilic patients (concerning hip, knee and ankle joints)-Hungarian experience.

INTRODUCTION: The surgical, arthroscopic synovectomy and radiosynovectomy (radiosynoviorthesis, RSO) all have great practical importance, since they can eliminate the posttraumatic joint bleedings and prevent the further joint destructions in hemophilic patients. The aim of this study was to examine the role of RSO in the prevention of joint bleedings in hemophilic patients. METHODS: 54 out of 684 RSO patients were hemophiliacs. Mean age of the patients was 32 years (range 14-51), therefore this is a relatively young patients' cohort. Radiosynovectomy was performed in 37 patients with hemophilia A and in 17 patients suffering from hemophilia B. Since hemophilia is a sex-linked (x-linked) recessive disorder, all of the patients were male. There was no acquired hemophiliac among the treated patients. RESULTS: The RSO resulted in a 95% decline in bleedings per year and eliminated the incidence of further bleedings in 55% of the treated joints. CONCLUSION: Our findings support the view that radiosynoviorthesis can be considered as the first choice treatment for posttraumatic joint bleedings of hemophilic patients.

Crystal structure of zwitterionic 3,3'-[1,1'-(butane-1,4-di-yl)bis-(1H-imidazol-3-ium-3,1-di-yl)]bis-(propane-1-sulfonate) dihydrate.

The crystal structure of the title compound, C16H26N4O6S2·2H2O, a water-soluble di-N-heterocyclic carbene ligand precursor was determined using a single crystal grown by the slow cooling of a hot N,N-di-methyl-formamide solution of the compound. The dihydrate crystallizes in the monoclinic space group P21/c, with half of the zwitterionic mol-ecule and one water mol-ecule of crystallization in the asymmetric unit. The remaining part of the mol-ecule is completed by inversion symmetry. In the mol-ecule, the imidazole ring planes are parallel with a plane-to-plane distance of 2.741 (2) Å. The supra-molecular network is consolidated by hydrogen bonds of medium strength between the zwitterionic mol-ecules and the water mol-ecules of crystallization, as well as by π-π stacking inter-actions between the imidazole rings of neighbouring mol-ecules and C-H⋯O hydrogen-bonding inter-actions.

The Fibrosis-4 Index Is Associated With Need for Mechanical Ventilation and 30-Day Mortality in Patients Admitted With Coronavirus Disease 2019.

The Fibrosis-4 Index (FIB-4), developed to predict fibrosis in liver disease, was used to identify patients with coronavirus disease 2019 who will require ventilator support as well as those associated with 30-day mortality. Multivariate analysis found obesity (odds ratio [OR], 4.5), diabetes mellitus (OR, 2.55), and FIB-4 ≥2.67 (OR, 3.09) independently associated with need for mechanical ventilation. When controlling for ventilator use, sex, and comorbid conditions, FIB-4 ≥2.67 was also associated with increased 30-day mortality (OR, 8.4 [95% confidence interval, 2.23-31.7]). Although it may not be measuring hepatic fibrosis, its components suggest that increases in FIB-4 may be reflecting systemic inflammation associated with poor outcomes.

Clinical Presentation and Outcomes of Acute Pericarditis in a Large Urban Hospital in the United States of America.

BACKGROUND: Acute pericarditis is the most common presentation of pericardial diseases. Although generally benign, complications such as constrictive pericarditis, cardiac tamponade, and recurrence can occur. RESEARCH QUESTION: What are the clinical factors associated with adverse outcomes in acute pericarditis? STUDY DESIGN AND METHODS: We used an informatics-based search engine to search for International Classification of Diseases codes related to pericardial disease between January 1, 2009 and November 14, 2018 and then extracted clinical information, including only patients meeting the European Society of Cardiology criteria for acute pericarditis. We then evaluated the predictive value of clinical characteristics for adverse outcomes (cardiac tamponade, constrictive pericarditis, failure of therapy, recurrences, or death). RESULTS: We identified 240 patients with a first episode of pericarditis (51 [34-62] years, 56% males and 50% white). Pericarditis was determined to be idiopathic in 126 (53%) cases and related to cardiac injury in 79 (33%). During a median follow-up time of 179 (20-450) days, 82 (34%) patients experienced at least one adverse outcome. Subacute presentation was an independent predictor of adverse outcomes. Patients with postcardiac injury pericarditis had a lower incidence in the composite of failure of treatment and recurrence (13% vs 26%; P = .022) compared with patients with idiopathic pericarditis. Troponin I measurements were obtained in 167 patients (70%). Elevated troponin I levels were associated with lower incidence of recurrences (4% vs 17%; P = .024) and of the composite outcome (13% vs 36%; P = .004). INTERPRETATION: Acute pericarditis is associated with at least one adverse outcome in 34% of patients. Subacute presentation and idiopathic etiology are associated with higher incidence of adverse outcomes, whereas elevated troponin I levels identify a group with reduced risk of recurrences.
