Arab American Mothers' HPV Vaccination Knowledge and Beliefs.

Little is known of Arab Americans' human papilloma virus vaccination (HPVV) behaviors. We explored associations between US Arab immigrant mothers' beliefs regarding HPVV for their children with socioeconomic, medical, and religious/cultural factors. A cross-sectional survey was conducted in New York City (August 2019-April 2021) with 162 Arab American immigrant women who had at least one child aged 9 through 26 years. Among those reporting that their child/children had not received the HPVV (63.5%), reasons included not having heard of it (67.3%) and lack of provider recommendation (59.4%). HPVV awareness and uptake, respectively, were more likely among those with education ≥ 10 years (p < .001 and p < .001, respectively), with more years in the US (p < .001 and p < .001), and with higher household income (p < .001 and p = .002). Participants with limited English proficiency were less likely to have HPVV awareness and uptake (p < .001 and p < .001). Christian religious affiliation was positively associated with HPVV awareness and uptake (p = .014 and p = .048). A greater number of years in the US was significantly associated with willingness to vaccinate if recommended by the doctor (p = .031). In open-ended responses, mothers indicated that they did not receive strong provider HPVV recommendations, potentially because of their providers' perceptions of their cultural backgrounds. Mothers indicated a desire for HPVV educational materials in Arabic to help them with decision making. Potential opportunities to augment HPVV uptake among Arab immigrants' children include increasing population knowledge, increasing provider recommendation, and providing culturally/religiously responsive HPVV education in English and Arabic.

Mesna Alleviates Cerulein-Induced Acute Pancreatitis by Inhibiting the Inflammatory Response and Oxidative Stress in Experimental Rats.

BACKGROUND: Acute pancreatitis (AP) is a sudden inflammation of the pancreas that may be life-threatening disease with high mortality rates, particularly in the presence of systemic inflammatory response and multiple organ failure. Oxidative stress has been shown to be involved in the pathophysiology of acute pancreatitis. AIM: This study is designed to investigate the possible effect of mesna on an experimental model of cerulein-induced acute pancreatitis. METHODS: Animals were divided into five groups: Group 1 served as a control group given the saline; group II (mesna group) received mesna at a dose of (100 mg/kg per dose, i.p.) four times; group III (acute pancreatitis group) received cerulein at a dose of (20 µg/kg/dose, s.c.) four times with 1-h intervals; group VI, cerulein + mesna, was treated with mesna at a dose of (100 mg/kg, i.p.) 15 min before each cerulein injection. RESULTS: Animals with acute pancreatitis showed elevated serum amylase and lipase levels. Biochemical parameters showed increased pancreatic tumor necrosis factors-α (TNF-α) and interleukin-1ß (IL-1ß) levels. A disturbance in oxidative stress markers was evident by elevated pancreatic lipid peroxides (TBARS) and decline in pancreatic antioxidants' concentrations including reduced glutathione (GSH); superoxide dismutase (SOD); and glutathione peroxidase (GSH-Px). Histological examination confirmed pancreatic injury. Pre-treatment with mesna was able to abolish the changes in pancreatic enzymes, oxidative stress markers (TBARS, SOD, GSH and GSH-Px), pancreatic inflammatory markers (TNF-α, IL-1ß) as well as histological changes. CONCLUSIONS: Mesna mitigates AP by alleviating pancreatic oxidative stress damage and inhibiting inflammation.

An experienced racial-ethnic diversity dataset in the United States using human mobility data.

Despite the importance of measuring racial-ethnic segregation and diversity in the United States, current measurements are largely based on the Census and, thus, only reflect segregation and diversity as understood through residential location. This leaves out the social contexts experienced throughout the course of the day during work, leisure, errands, and other activities. The National Experienced Racial-ethnic Diversity (NERD) dataset provides estimates of diversity for the entire United States at the census tract level based on the range of place and times when people have the opportunity to come into contact with one another. Using anonymized and opted-in mobile phone location data to determine co-locations of people and their demographic backgrounds, these measurements of diversity in potential social interactions are estimated at 38.2 m × 19.1 m scale and 15-minute timeframe for a representative year and aggregated to the Census tract level for purposes of data privacy. As well, we detail some of the characteristics and limitations of the data for potential use in national, comparative studies.

Paroxysmal atrial fibrillation and hemochromatosis: a narrative review.

Paroxysmal atrial fibrillation (PAF) and hemochromatosis have a complex relationship. This review explores its mechanisms, prevalence, correlations, and clinical manifestations. Hereditary hemochromatosis (HH) involves iron overload due to HFE protein mutations, while atrial fibrillation (AF) is characterized by irregular heart rhythms. Iron overload in hemochromatosis can promote cardiac arrhythmias. AF is prevalent in developed countries and may be linked to cryptogenic strokes. Genetic variations and demographic factors influence the occurrence of both conditions. HH affects multiple organ systems, including the heart, while AF causes palpitations and reduced exercise tolerance. Diagnosis involves iron markers, genotypic testing, and electrocardiogram (ECG) findings. Treatment strategies focus on reducing iron levels in hemochromatosis and managing AF through antithrombotic therapy and rhythm control. Untreated hemochromatosis carries a higher risk of complications, and PAF is associated with increased cardiovascular-related mortality. For better understanding of the mechanisms and to improve management, additional studies are required. Tailored approaches and combined treatments may enhance patient outcomes.

Association Between Type 1 Diabetes Mellitus and Eating Disorders: A Systematic Review and Meta-Analysis.

BACKGROUND: Previous meta-analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. METHODS: A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms "T1DM," "Eating Disorders" and "Bulimia." Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. RESULTS: T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84-3.32, p-value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18-6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18-1.98, p-value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91-4.12, p-value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27-3.23, p-value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. CONCLUSION: Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist.

Anti-EGFR VHH-armed death receptor ligand-engineered allogeneic stem cells have therapeutic efficacy in diverse brain metastatic breast cancers.

Basal-like breast cancer (BLBC) shows brain metastatic (BM) capability and overexpresses EGFR and death-receptors 4/5 (DR4/5); however, the anatomical location of BM prohibits efficient drug-delivery to these targetable markers. In this study, we developed BLBC-BM mouse models featuring different patterns of BMs and explored the versatility of estem cell (SC)-mediated bi-functional EGFR and DR4/5-targeted treatment in these models. Most BLBC lines demonstrated a high sensitivity to EGFR and DR4/5 bi-targeting therapeutic protein, EVDRL [anti-EGFR VHH (EV) fused to DR ligand (DRL)]. Functional analyses using inhibitors and CRISPR-Cas9 knockouts revealed that the EV domain facilitated in augmenting DR4/5-DRL binding and enhancing DRL-induced apoptosis. EVDRL secreting stem cells alleviated tumor-burden and significantly increased survival in mouse models of residual-tumor after macrometastasis resection, perivascular niche micrometastasis, and leptomeningeal metastasis. This study reports mechanism based simultaneous targeting of EGFR and DR4/5 in BLBC and defines a new treatment paradigm for treatment of BM.

Inhibition of NF-κB and the oxidative stress -dependent caspase-3 apoptotic pathway by betaine supplementation attenuates hepatic injury mediated by cisplatin in rats.

BACKGROUND: Cisplatin is a major anti-cancer drug commonly used in the treatment of various cancers; nevertheless, the associated hepatotoxicity has limited its clinical application. The aim of this investigation is to test the impact of betaine supplementation on cisplatin-induced hepatotoxicity. METHODS: Animals were allocated into four groups; normal control group (control betaine group (250 mg/kg/day, po for twenty six days), cisplatin group (single injection of 7 mg/kg, ip) and betaine + cisplatin group (received betaine for twenty one days before cisplatin injection and daily after cisplatin for five days). RESULTS: Cisplatin-induced liver injury was confirmed by increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Cisplatin elevated lipid peroxides, and reduced the concentrations of reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase and superoxide dismutase (SOD) in hepatic tissues. Cisplatin increased the inflammatory mediators; nitrite and tumor necrosis factor-α (TNF- α) in hepatic tissues. Increased gene expressions of the apoptotic marker, caspase-3 and nuclear factor-kappa B (NF-κB) were observed in hepatic tissues of cisplatin-treated rats. All these changes were further confirmed by histopathological findings in cisplatin group. Pre-treatment with betaine reduced serum aminotransferases (ALT and AST), and lowered hepatic concentrations of lipid peroxides, nitrite and TNF-α while increased SOD, GSH, catalase, and GSH-Px concentrations. Moreover, the histological and immunohistochemical changes were improved. CONCLUSION: The suppression of NF-κß-mediated inflammation, oxidative stress, and caspase-3 induced apoptosis are possible mechanisms to the observed hepatoprotective effect of betaine.
