Prostaglandin E1 administration post liver transplantation and renal outcomes:A retrospective single center experience

BACKGROUND Prostaglandin E1(PGE1),or alprostadil,is a potent vasodilator that improves hepatic blood flow and reduces ischemia-reperfusion injury post-liver transplantation(LT).However,the benefits of PGE1 on renal function after LT have not yet been well described.AIM To assess the impact of PGE1 administration on renal function in patients who underwent liver or liver-kidney transplant.METHODS This retrospective study included all patients who underwent liver or liverkidney transplant at our institution from January,2011 to December,2021.Patients were classified based on whether they received PGE1.PGE1 was administered post-LT to those with transaminases>1000 U/L in the immediate postoperative period.Demographics,post-LT treatments and/or complications,renal function,and survival were analyzed.Multivariable logistic regression analysis was performed,and a two-tailed P value<0.05 was considered statistically significant.RESULTS A total of 145 patients underwent LT,with 44(30%)receiving PGE1.Baseline patient characteristics were comparable,except the PGE1 group had significantly higher aspartate aminotransferase(AST)(1961.9 U/L±1862.3 U/L vs 878 U/L±741.4 U/L,P=0.000),alanine aminotransferase(1070.6 U/L±895 U/L vs 547.7 U/L±410 U/L,P=0.000),international normalized ratio on post-LT day 1(2±0.74 vs 1.8±0.4,P=0.03),a longer intensive care unit stay(8.1 days±11.8 days vs 3.8 days±4.6 days,P=0.003),more vasopressor use(55.53 hours±111 hours vs 16.33 hours±26.3 hours,P=0.002),and higher immediate postoperative complications(18.6%vs 4.9%,P=0.04).The PGE1 group also had a significantly higher 90-day readmission rate(29.6%vs 13.1%,P=0.02)and lower 1-year liver graft survival(87.5%vs 98.9%,P=0.005).However,30-day readmission(31.6%vs 27.4%,P=0.64),LT complications(hepatic artery thrombosis,biliary complications,rejection of liver graft,cardiomyopathy),1-year patient survival(96.9%vs 97.8%,P=0.77),overall liver graft survival,and overall patient survival were similar between the two groups(95.4%vs 93.9%,P=0.74 and 88.4%vs 86.9%,P=0.81 respectively).Although the PGE1 group had a significantly lower glomerular filtration rate(eGFR)on post-LT day 7(46.3 mL/minute±26.7 mL/minute vs 62.5 mL/minute±34 mL/minute,P=0.009),the eventual need for renal replacement therapy(13.6%vs 5.9%,P=0.09),the number of dialysis sessions(0.91 vs 0.27,P=0.13),and eGFR at 1-month(37.2 mL/minute±35.9 mL/minute vs 42 mL/minute±36.9 mL/minute,P=0.49),6-months(54.8 mL/minute±21.6 mL/minute vs 62 mL/minute±21.4 mL/minute,P=0.09),and 12-months(63.7 mL/minute±20.7 mL/minute vs 62.8 mL/minute±20.3 mL/minute,P=0.85)post-LT were similar to those in the non-PGE1 group.CONCLUSION In patients who received PGE1 for ischemia-reperfusion injury,despite immediate acute renal injury post-LT,the renal function at 1-month,6-months,and 12-months post-LT was similar compared to those without ischemiareperfusion injury.Prospective clinical trials are needed to further elucidate the benefits of PGE1 use in renal function.

The definition,characteristics and roles of experiencing rural tourism were discussed in this study,which confirmed the relationship between the development of experiencing rural tourism and the new socialist countryside construction,and some development strategies were put forward.

An Uploaded Experience Too many tourists are experiencing life through a lens

REMEMBER the days when people used to have a phone, a computer and a camera？ I do - simply because it wasn＇t that long ago. However, as technology hurtles along at the speed of light, it might have escaped some people＇s attention that all these three devices now come together in the form of a smartphone, There＇s no need to carry all three devices when visiting a tourist site or monument - your handy smartphone can take a picture, log on to the Internet to post your picture on social media, and then use the calling function to tell your friends about the pictures you＇ve just posted.

CO_2 insufflation for potentially diffi cult colonoscopies: Effi cacy when used by less experienced colonoscopists

AIM： To clarify the effectiveness of CO2 insufflation in potentially difficult colonoscopy cases, particularly in relation to the experience level of colonoscopists. METHODS： One hundred twenty potentially difficult cases were included in this study, which involved females with a low body mass index and patients with earlier abdominal and/or pelvic open surgery or previously diagnosed left-side colon diverticulosis. Patients receiving colonoscopy examinations without sedation using a pediatric variable-stiffness colonoscope were divided into two groups based on either CO2 or standard air insuffiation. Both insufflation procedures were also evaluated according to the experience level of the respective colonoscopists who were divided into an experienced colonoscopist （EC） group and a less experienced colonoscopist （LEC） group. Study measurements included a 100-mm visual analogue scale （VAS） for patient pain during and after colonoscopy examinations, in addition to insertion to the cecum and withdrawal times. RESULTS： Examination times did not differ, however, VAS scores in the CO2 group were significantly better than in the air group （P〈 0.001, two-way ANOVA） from immediately after the procedure and up to 2 h later. There were no significant differences between either insufflation method in the EC group （P = 0.29）, however, VAS scores for CO2 insufflation were significantly better than air insufflation in the LEC group （P = 0.023） immediately after colonoscopies and up to 4 h afterwards. CONCLUSION： CO2 insufflation reduced patient pain after colonoscopy in potentially difficult cases when performed by LECs.

Hepatitis E virus is a leading cause of acute-on-chronic liver disease:experience from a tertiary centre in Bangladesh

BACKGROUND:Acute-on-chronic liver failure(ACLF) is common in Bangladesh.Acute viral E hepatitis is sporadically encountered in this country each year,with a rising incidence in the rainy season.This study aimed to identify the etiology of ACLF in Bangladesh. METHODS:In this retrospective study,69 ACLF patients were included.They presented to our department at the Bangabandhu Sheikh Mujib Medical University in Dhaka.History of diseases was recorded and appropriate investigations were conducted in all patients. RESULTS:Acute hepatitis E virus(HEV)infection was positive in 21.7%(15/69)of the patients,while 14.5% (10/69)had septicemia.Upper gastrointestinal tract hemorrhage was seen in 4.3%of the patients(3/69),while another 4.3%(3/69)had a positive history for alcohol or drugs.None of the patients tested positive for hepatitis A virus infection and no evidence of hepatitis B virus flare was found in any patient.No specific cause for ACLF could be identified. CONCLUSIONS:Acute HEV infection is a leading cause of ACLF in Bangladesh.Many patients were thought to have decompensation of cirrhosis,but subsequently were recognized as having ACLF by a retrospective review according to the definition of the Asian Pacific Association for the Study of the Liver Working Party Meeting on ACLF in New Delhi in early 2008.

Mental Health Problems Experienced by HIV Positive Adolescents;A Case of Choma District, Zambia

Several scholars have reported high mental health problems among adolescents with Human Immunodeficiency Virus (HIV) globally. However, little is known about the mental health of this peculiar group of young people in Choma district. This study aimed to determine the mental health problems experienced by HIV positive adolescents in Choma District. Using the Strengths and Difficulties Questionnaire (SDQ), data were obtained from 103 HIV positive adolescents receiving treatment at Choma General Hospital plus a corresponding number of parents/care givers. Information about mental health services was obtained qualitatively from 10 nurses working in the mental health unit and the Antiretroviral (ART) clinic. The results showed that more than three quarters of the adolescents had mental health problems. Of this number, 57.3 percent had multiple mental health problems: predominantly emotional and peer problems. The study also found a statistically significant relationship between level of stigma and presence of mental health problems (X2 = 1.123, P = 0.003). In conclusion, the study demonstrated that multiple mental health problems particularly emotional and peer problems are prevalent among adolescents with HIV/AIDS yet are most often undiagnosed. In addition, adolescents with high levels of internalized stigma are more likely to have multiple mental health problems. The findings suggest the need to integrate psychiatric services into routine care of HIV infected adolescents, routine screening for mental health problems and provision of continued professional development among nurses managing these patients.
