| 3 | Detection of pancreatic cancer by indocyanine green-assisted fluorescence imaging in the first and second near-infrared windows显示文摘Dear Editor,In the United States,pancreatic cancer is considered the fourth most common reason for cancer-related deaths;over 53%of patients are diagnosed at end-stage with a 5-year survival rate of less than 3%[1].Incomplete removal of all cancerous cells generally leads to local recurrence of pancreatic cancer[2].Thus,the detection of tumor margin status plays an essential role in the complete resection of pancreatic cancer.Most of the existing imaging modalities,like computed tomography and magnetic resonance imaging,are primarily used for preoperative planning;these modalities also have issues of bulky equipment,radiation concerns,and slow imaging speed[2].Thus,these modalities can neither provide an intraoperative diagnosis of cancer with high sensitivity and specificity nor be used to define tumor margins[3]. | Zhongqiang Li Zheng Li Alexandra Ramos J.Philip Boudreaux Ramcharan Thiagarajan Yvette Bren Mattison Michael E.Dunham Andrew J McWhorter Qing Chen Jian Zhang Ji-Ming Feng Yanping Li Shaomian Yao Jian Xu | 2021 | Cancer Communications2021，41，12： | 1 |
| 4 | COVID-19 among African Americans and Hispanics:Does gastrointestinal symptoms impact the outcome?显示文摘BACKGROUND The coronavirus disease 2019(COVID-19)disproportionately affected African Americans(AA)and Hispanics(HSP).AIM To analyze the significant effectors of outcome in African American patient population and make special emphasis on gastrointestinal(GI)symptoms,laboratory values and comorbidities METHODS We retrospectively evaluated the medical records of 386 COVID-19 positive patients admitted at Howard University Hospital between March and May 2020.We assessed the symptoms,including the GI manifestations,comorbidities,and mortality,using logistic regression analysis.RESULTS Of these 386 COVID-19 positive patients,257(63.7%)were AAs,102(25.3%)HSP,and 26(6.45%)Whites.There were 257(63.7%)AA,102(25.3%)HSP,26(6.45%)Whites.The mean age was 55.6 years(SD=18.5).However,the mean age of HSP was the lowest(43.7 years vs 61.2 for Whites vs 60 for AAs).The mortality rate was highest among the AAs(20.6%)and lowest among HSP(6.9%).Patients with shortness of breath(SOB)(OR2=3.64,CI=1.73-7.65)and elevated AST(OR2=8.01,CI=3.79-16.9)elevated Procalcitonin(OR2=8.27,CI=3.95-17.3),AST(OR2=8.01,CI=3.79-16.9),ferritin(OR2=2.69,CI=1.24-5.82),and Lymphopenia(OR2=2.77,CI=1.41-5.45)had a high mortality rate.Cough and fever were common but unrelated to the outcome.Hypertension and diabetes mellitus were the most common comorbidities.Glucocorticoid treatment was associated with higher mortality(OR2=5.40,CI=2.72-10.7).Diarrhea was prevalent(18.8%),and GI symptoms did not affect the outcome.CONCLUSION African Americans in our study had the highest mortality as they consisted of an older population and comorbidities.Age is the most important factor along with SOB in determining the mortality rate.Overall,elevated liver enzymes,ferritin,procalcitonin and C-reactive protein were associated with poor prognosis.GI symptoms did not affect the outcome.Glucocorticoids should be used judiciously,considering the poor outcomes associated with it.Attention should also be paid to monitor liver function during COVID-19,especially in AA and HSP patients with higher disease severity. | Hassan Ashktorab Adeleye Folake Antonio Pizuorno Gholamreza Oskrochi Philip Oppong-Twene NuriTamanna Maryam Mehdipour Dalivand Lisa N Umeh Esther S Moon Abdoul Madjid Kone Abigail Banson Cassandra Federman Edward Ramos Eyitope Ola Awoyemi Boubini Jones Wonni Eric Otto Guttu Maskalo Alexandra Ogando Velez Sheldon Rankine Camelita Thrift Chiamaka Ekwunazu Derek Scholes LakshmiGayathri Chirumamilla Mohd Elmugtaba Ibrahim Brianna Mitchell Jillian Ross Julencia Curtis Rachel Kim Chandler Gilliard Joseph Mathew Adeyinka Laiyemo Angesum Kibreab Edward Lee Zaki Sherif Babak Shokrani Farshad Aduli Hassan Brim | 2021 | World Journal of Clinical Cases2021，9，28： | 0 |
