The Efficacy of On-Site Integration Screening and Microelimination Programs for Chronic Hepatitis C in a Detection Center: A Comparison of the Treatment Outcomes and Characteristics of Incarcerated Patients and Outpatients.

We aimed to analyze the different patient characteristics and treatment outcomes (such as sustained viral response, SVR) between incarcerated patients with chronic hepatitis C (CHC) and those with CHC from the outpatient department through an on-site integrated screening and microelimination program in a detection center. In this retrospective study, which ran from May 2021 to April 2022, we included 32 consenting male prisoners aged at least 20 years who were willing to participate in the study. Members of the control group (who received DAAs in an outpatient setting) were selected from the treated CHC patient databank of individuals who received DAA regimens at Chi Mei Hospital between January 2021 and December 2022. The patients in the two groups did not differ significantly in terms of age, FIB-4 score, HCV RNA, HBV coinfection, hemogram findings, coagulation profiles, and renal function tests. However, the patients in the incarcerated group had a significantly different genotype distribution compared to the control group, significantly lower liver enzyme levels, and higher albumin and bilirubin levels compared to those in the control group. The rate of SVR to DAA treatment obtained among incarcerated patients did not differ significantly from that obtained among patients in the control group. Loss to follow-up (for several reasons) is a major reason for treatment discontinuation among these patients.

Clinical effectiveness of nirmatrelvir plus ritonavir in the treatment of COVID-19 in patients with cirrhosis.

OBJECTIVES: This retrospective cohort study assessed the clinical effectiveness of nirmatrelvirplus ritonavir (NMV-r) in treating COVID-19 in patients with liver cirrhosis(LC). METHODS: The data of non-hospitalized adult patients with LC who had COVID-19 were selected from the TriNetX platform for the period between 1 March 20201 March 2020, and 31 December 202231 December 2022. Propensity score matching was used to match patients receiving NMV-r (theNMV-r group) with those not receiving NMV-r (the control group). Hazard ratios(HRs) along with 95% confidence intervals (CIs) for the primary outcome - a composite of all-cause hospitalization or mortality during the 30-day follow-up period - were calculated and compared. RESULTS: Two cohorts of 2,369 patients each with balanced baseline characteristics were identified.During the follow-up period, the NMV-r group had a lower risk of all-cause hospitalization or mortality (HR, 0.642;95% CI, 0.503-0.819) than did the control group.NMV-r was also associated with a reduced risk of individual all-cause hospitalization (HR 0.681, 95% CI 0.530-0.876])and all-cause mortality (HR, 0.270; 95% CI,0.129-0.562). This association was consistently observed in the subgroups of age, sex, vaccination status, and LC severity. CONCLUSIONS: NMV-r can reduce all-cause hospitalization and mortality among patients with LC who have COVID-19.

Iatrogenic Kaposi sarcoma of the small bowel in Crohn's disease following short-term use of immunomodulators: a case report and review of the literature.

BACKGROUND: Kaposi sarcoma is a vascular tumor highly related to human herpesvirus-8 and Kaposi sarcoma-associated herpesvirus. Kaposi sarcoma usually manifests as skin or mucosal lesions; involvement in visceral organs such as the gastrointestinal tract is rare. Kaposi sarcoma can occur in immunocompromised patients receiving immunosuppressive therapy, in which case it is known as iatrogenic Kaposi sarcoma or drug-induced Kaposi sarcoma. Intestinal Kaposi sarcoma in patients with inflammatory bowel disease is extremely rare. CASE PRESENTATION: A 46-year-old East Asian male with recently diagnosed Crohn's disease was administered azathioprine and prednisolone; however, the patient complained of persistent abdominal pain and diarrhea following treatment. Endoscopy revealed small bowel Kaposi sarcoma. The patient was treated with systemic chemotherapy successfully without relapse. CONCLUSIONS: This is the fifth case of Kaposi sarcoma developed over the small intestine in a patient with Crohn's disease following administration of immunomodulators. Additionally, this case indicated that even short-term immunomodulator use can induce Kaposi sarcoma in patients with inflammatory bowel disease. Thus, in patients with inflammatory bowel disease, if symptoms are aggravated or do not abate after immunomodulators prescription, and before intending to upgrade immunomodulators, endoscopy should be considered. Finally, chemotherapy can also be considered if both medication withdrawal and surgical intervention are not feasible.

[A proposal to improve operating room nursing personnel adherence to mandated X-ray protection measures].

BACKGROUND: Cognition of and attitudes toward personal radiation protection amongst operating room nurses have been shown to be inappropriate and insufficient. Research has shown that adherence to full radiation protection measures in the operating room is at only 64 percent. Improvements targeting radiation protection measure compliance were thus developed in order to enhance employee welfare and working environment safety. PURPOSE: Raise the rate at which radiation protection measures are properly executed in order to provide a safe, high quality working environment for nursing staff and to establish a safe working environment. RESOLUTION: The following were identified as able to influence positively the proper implementation of radiation protection measures: (1) hold programs and training courses on radiation protection; (2) ensure adequate rack space in the operating room for lead-lined vests, install warning signals to indicate when a radiation source is active, and mandate that all personnel wear radiation monitoring badges; (3) edit and update radiation protection manuals; and (4) set up standard operation procedures for maintenance and radiation facility cleaning. RESULTS: Correct execution of radiation protection measures rose from 64% to 100%; cognition of radiation hazards and protection increased from 68.4 to 100 (on a scale of 0 to 100); and correct radiation facility maintenance and cleaning rose from 43% to 100%. CONCLUSIONS: Enhancement of radiation protection cognition through in-service-training courses and the provision of appropriate protection facilities can raise radiation protection and self-protection abilities amongst medical staff. We strongly recommend that a course on radiation protection be included in the continuing nursing education curriculum for operating room staff. Enhancing radiation protection cognition further is necessary.

In vitro and in vivo antipseudomonal activity, acute toxicity, and mode of action of a newly synthesized fluoroquinolonyl ampicillin derivative.

Compounds N-(6,7-difluoroquinolonyl)-ampicillin (AU-1) and N-(6-fluoroquinolonyl)-ampicillin (FQ-1), synthesized by coupling of the carboxyl group of 6,7-difluoroquinolone (FP-3) and 6-fluoroquinolone (FP4), respectively, with the alpha-amino-group of ampicillin side chain, exhibit antipseudomonal activity similar to and lower acute toxicity than that of norfloxacin, whereas neither ampicillin nor the fluoroquinolone moieties, compound FP-3 or FP4, alone have such activity. Also, AU-1 and FQ-1 are active against tested clinical isolates of Pseudomonas aeruginosa that are highly resistant to norfloxacin, gentamicin, or both. The therapeutic efficacies of FQ-1 and norfloxacin were assessed and compared in neutropenic mice infected with a 90% lethal dose of P aeruginosa. Mice intraperitoneally administered FQ-1 (10 mg/kg) 4, 8, 24, and 48 hours after infection had survival rates as high as 80%, comparable to those of mice treated with norfloxacin at the same dosage and dosing schedule. The study of protoplast formation revealed that FQ-1 did not inhibit cell-wall biosynthesis but did induce cell filamentation of Bacillus subtilis at a level close to its minimal inhibition concentration. Both AU-1 and FQ-1 were able to intercalate into the double-stranded DNA. However, that FQ-1 lost such activity after it was treated with penicillinase suggests that the lactam-ring structure in ampicillin moiety of FQ-1 was hydrolyzed by penicillinase and that the hydrolyzed structure of FQ-1 does not own DNA-intercalation activity.
