Partnering With Churches to Address COVID-19 Vaccine Hesitancy and Uptake in Trustworthy Contexts.

The Black church has long been seen as a crucial partner in addressing public health issues. This paper describes the development, implementation, and evaluation of a community-engaged church intervention addressing COVID-19 vaccine hesitancy in underserved Black communities in Jefferson County, Alabama. We partnered with churches to implement and evaluate the intervention between March and June of 2022 and found that our church partners were capable of significant messaging reach, particularly through electronic means.

Regulation of miRNA-155-5p ameliorates NETosis in pulmonary fibrosis rat model via inhibiting its target cytokines IL-1ß, TNF-α and TGF-ß1.

Idiopathic pulmonary fibrosis (IPF) is an age-related inflammatory disease with no cure up till now.It is accompanied by neutrophils infiltration as the main responders to inflammation and fibrosis. Importantly, neutrophils release neutrophil extracellular traps (NETs) through NETosis process. The function of microRNAs during inflammation became of great biological attention. Owing to microRNAs' central role in immune system, microRNA-155-5p (miR-155-5p) is intensely involved in the inflammatory response. Capsaicin (Cap) is a bioactive compound that exhibits antioxidative and anti-inflammatory functions. Recent studies have shown its role in regulation of certain microRNAs' expressions. Accordingly, the present study aims to investigate the effect of miR-155-5p regulation in suppressing NETs production via ameliorating its target inflammatory cytokines, IL-1ß, TNF-α and TGF-ß1, in bleomycin (BLM)-induced pulmonary fibrosis rat model treated by Cap. The obtained results demonstrated that miR-155-5p downregulation was associated with significant decrease in IL-1ß, TNF-α, TGF-ß1, which consequently, reduced hydroxyproline (HYP), NETs activity markers as NE and PAD-4, and alleviated CTGF levels in lung tissues of animals treated by Cap. Furthermore, NETosis ultrastructure examination by transmission electron microscope (TEM), MPO immunohistochemical staining and histopathological studies confirmed an abolishment in NETs formation and an improvement in lung tissue architecture in Cap-treated rats. This study concluded that Cap quenched the inflammatory response through interrupting IL-1ß, TNF-α and TGF-ß1 pathway via modulating miR-155-5p expression. In addition, Cap was able to alleviate pulmonary NETosis markers by restraining NETs activity markers. These findings provide novel insight into the application of Cap-based treatment in ameliorating pulmonary damage in IPF.

Africa Guidelines for Hepatocellular Carcinoma Buildup Process.

PURPOSE: Hepatocellular carcinoma (HCC), the fourth most common cancer in Africa, has a dismal overall survival of only 3 months like in sub-Saharan Africa. This is affected by the low gross domestic product and human development index, absence of coherent guidelines, and other factors. METHODS: An open forum for HCC-experienced health care workers from Africa and the rest of the world was held in October 2021. Participants completed a survey to help assess the real-life access to screening, diagnoses, and treatment in the North and Southern Africa (NS), East and West Africa (EW), Central Africa (C), and the rest of the world. RESULTS: Of 461 participants from all relevant subspecialties, 372 were from Africa. Most African participants provided hepatitis B vaccination and treatment for hepatitis B and C. More than half of the participants use serum alpha-fetoprotein and ultrasound for surveillance. Only 20% reported using image-guided diagnostic liver biopsy. The Barcelona Clinic Liver Cancer is the most used staging system (52%). Liver transplant is available for only 28% of NS and 3% EW. C reported a significantly lower availability of resection. Availability of local therapy ranged from 94% in NS to 62% in C. Sorafenib is the most commonly used systemic therapy (66%). Only 12.9% reported access to other medications including immune checkpoint inhibitors. Besides 42% access to regorafenib in NS, second-line treatments were not provided. CONCLUSION: Similarities and differences in the care for patients with HCC in Africa are reported. This reconfirms the major gaps in access and availability especially in C and marginally less so in EW. This is a call for concerted multidisciplinary efforts to achieve and sustain a reduction in incidence and mortality from HCC in Africa.

Physical Activity among Colorectal Cancer Patients and Survivors in Egypt.

INTRODUCTION: Understanding physical activity (PA) levels is important when developing tertiary cancer prevention interventions, especially in Egypt where colorectal cancer (CRC) is more often diagnosed at later stages and at a younger age of onset (≤40 years). METHODS: We assessed PA levels among CRC patients and survivors in Alexandria, Egypt. All participants completed two self-reported PA assessments: Global Physical Activity Questionnaire (GPAQ) and Godin Leisure-Time Exercise Questionnaire (GLTEQ). Participants could opt to wear an accelerometer for seven days. Results were compared against WHO recommendations of ≥150 minutes or ≥600 metabolic equivalents of tasks (METs) of moderate-to-vigorous PA weekly. RESULTS: Of 86 participants enrolled, all completed the surveys and 29 agreed to accelerometer use. Prevalence of meeting PA recommendations was 62.8% based on the GPAQ, 14.0% based on GLTEQ, and 41% based on accelerometer. Based on the GPAQ, very few respondents reported vigorous occupational, vigorous recreational, or moderate recreational activity (median = 0 with interquartile range [IQR] of 0 - 0 weekly minutes for all three) while most activity resulted from moderate occupational and transportation (median [IQR] of 60 [0-840] and 60 [0-187.5] weekly minutes, respectively). Participants meeting PA recommendations were less likely to be married (p = 0.043) according to GPAQ and more likely to be female (p=0.047) and early cancer stage (p=0.007) by GLTEQ. CONCLUSION: Non-leisure free-living PA is a major contributor to meeting PA recommendations while leisure-time PA is a potential target for future interventions that increase PA in this population.

Microbiome diversity in African American, European American, and Egyptian colorectal cancer patients.

Purpose: Although there is an established role for microbiome dysbiosis in the pathobiology of colorectal cancer (CRC), CRC patients of various race/ethnicities demonstrate distinct clinical behaviors. Thus, we investigated microbiome dysbiosis in Egyptian, African American (AA), and European American (EA) CRC patients. Patients and methods: CRCs and their corresponding normal tissues from Egyptian (n = 17) patients of the Alexandria University Hospital, Egypt, and tissues from AA (n = 18) and EA (n = 19) patients at the University of Alabama at Birmingham were collected. DNA was isolated from frozen tissues, and the microbiome composition was analyzed by 16S rRNA sequencing. Differential microbial abundance, diversity, and metabolic pathways were identified using linear discriminant analysis (LDA) effect size analyses. Additionally, we compared these profiles with our previously published microbiome data derived from Kenyan CRC patients. Results: Differential microbiome analysis of CRCs across all racial/ethnic groups showed dysbiosis. There were high abundances of Herbaspirillum and Staphylococcus in CRCs of Egyptians, Leptotrichia in CRCs of AAs, Flexspiria and Streptococcus in CRCs of EAs, and Akkermansia muciniphila and Prevotella nigrescens in CRCs of Kenyans (LDA score >4, adj. p-value <0.05). Functional analyses showed distinct microbial metabolic pathways in CRCs compared to normal tissues within the racial/ethnic groups. Egyptian CRCs, compared to normal tissues, showed lower l-methionine biosynthesis and higher galactose degradation pathways. Conclusions: Our findings showed altered mucosa-associated microbiome profiles of CRCs and their metabolic pathways across racial/ethnic groups. These findings provide a basis for future studies to link racial/ethnic microbiome differences with distinct clinical behaviors in CRC.

The Pittman Scholar Program for junior faculty recognition at the University of Alabama at Birmingham Heersink School of Medicine.

The University of Alabama at Birmingham Heersink School of Medicine established the Pittman Scholars Program in 2015 to elevate scientific impact and to support the recruitment and retention of highly competitive junior faculty. The authors examined the impact of this program on research productivity and on faculty retention. The authors evaluated publications and extramural grant awards and available demographic data for the Pittman Scholars compared to all junior faculty in the Heersink School of Medicine. From 2015 to 2021, the program awarded a diverse group of 41 junior faculty members across the institution. For this cohort, ninety-four new extramural grants were awarded and 146 grant applications were submitted since the inception of the scholar award. Pittman Scholars published a total of 411 papers during the term of the award. The faculty retention rate of the scholars was 95%, comparable to that of all Heersink junior faculty, with 2 recipients being recruited to other institutions. The implementation of the Pittman Scholars Program has been an effective strategy to celebrate scientific impact and acknowledge junior faculty members as outstanding scientists at our institution. The Pittman Scholars award allows junior faculty to use funds for their research program, publications, collaborations, and career advancement. The Pittman Scholars are recognized at local, regional, and national levels for the work they are contributing to academic medicine. The program has served as an important pipeline faculty development program and an avenue for individual recognition for research-intensive faculty.

Effect of laser acupuncture on pain and density of bone in osteoporotic postmenopausal women: a randomized controlled trial.

OBJECTIVE: This study aimed to evaluate the value of laser acupuncture (LA) on forearm bone mineral density (BMD) and wrist pain in osteoporotic postmenopausal women. METHODS: Sixty-eight postmenopausal women diagnosed with osteoporosis were randomly allocated equally to one of two sets. The drug-only group received calcium and vitamin D 3 supplement containing fluoride daily for 12 weeks, whereas the drug/LA group received LA therapy for 20 minutes per session, three sessions weekly, in addition to the same supplementation. The primary outcome parameter was assessment of BMD of the nondominant arm. Other outcomes included wrist pain. RESULTS: There was a highly significant improvement in the T-score of forearm BMD in both groups (-2.844 ± 0.476 to -2.597 ± 0.478 and -2.944 ± 0.486 to -1.652 ± 0.728 in the drug-only and drug/LA groups, respectively; P < 0.0001) and visual analog scale score (7.50 ± 0.79 to 4.24 ± 1.07 and 7.24 ± 0.82 to 3.09 ± 0.75 in the drug-only and drug/LA group, respectively; P < 0.0001). The improvement of both BMD and pain score was significantly higher in the drug/LA group (-1.303 and 4.15) compared with the drug-only group (-0.247 and 3.26; P < 0.0001). CONCLUSIONS: LA in combination with calcium and vitamin D supplementation containing fluoride is an effective modality in improving forearm BMD and reducing pain in osteoporotic postmenopausal women.
