Donor-derived carbapenem-resistant gram-negative bacterial infections in solid organ transplant recipients: Active surveillance enhances recipient safety.

Donor-derived infections (DDIs) caused by carbapenem-resistant gram-negative bacteria (CR-GNB) in solid organ transplant recipients are potentially life-threatening. In this prospective study, we evaluated the incidence, factors associated with transmission, and the outcome of recipients with unexpected CR-GNB DDIs after the implementation of our local active surveillance system (LASS). LASS provides for early detection of unexpected donor CR-GNB infections, prophylaxis of recipients at high risk, and early diagnosis and treatment of DDIs. Whole genome sequencing confirmed DDI. Among 791 recipients, 38 (4.8%) were at high risk of unexpected CR-GNB DDI: 25 for carbapenem-resistant Enterobacterales (CRE) and 13 for carbapenem-resistant Acinetobacter baumannii (CRAB). Transmission did not occur in 27 (71%) cases, whereas DDIs occurred in 9 of 25 of CRE and 2 of 13 of CRAB cases. Incidence of CR-GNB DDI was 1.4%. Recipients of organs with CR-GNB-positive preservation fluid and liver recipients from a donor with CRE infection were at the highest risk of DDI. There was no difference in length of hospital stay or survival in patients with and without CR-GNB DDI. Our LASS contains transmission and mitigates the negative impacts of CR-GNB DDI. Under well-defined conditions, organs from donors with CR-GNB may be considered after a thorough evaluation of the risk/benefit profile.

Outcomes of Phacoemulsification With or Without Kahook Dual Blade Goniotomy for Glaucoma Patients with Cataract.

PRECIS: This meta-analysis examines the comparative efficacy of phacoemulsification with and without Kahook Dual Blade Goniotomy in individuals with glaucoma and cataract, aiming to elucidate optimal surgical approaches for coexisting conditions. PURPOSE: The purpose of this current study is to compare the effect of combining Kahook Dual Blade (KDB) goniotomy with phacoemulsification versus phacoemulsification alone on intraocular pressure (IOP) and medication reduction in patients with glaucoma and cataract. METHODS: We conducted a systematic review and meta-analysis utilizing computer databases, including Embase (OVID), MEDLINE (OVID and PubMed), CINHAL (EBSCO), and the Cochrane Library (Wiley). We included studies examining the IOP-lowering effect of KDB goniotomy combined with phacoemulsification and studies that examined the IOP-lowering effect of phacoemulsification alone in patients with open angle glaucoma or ocular hypertension. The mean reduction of IOP and the reduction in topical glaucoma eye drops after surgery were determined. RESULTS: A total of 26 studies were included reporting on 1659 patients, 684 patients underwent phacoemulsification alone and 975 underwent combined phacoemulsification and KDB goniotomy. A 9.62% IOP reduction from baseline occurred following phacoemulsification as a solo procedure compared to 22.74% following combined KDB goniotomy with phacoemulsification. Similarly, the combination of the procedures caused a significant drop in the mean number of glaucoma eye drops used (mean reduction=1.35, 95% CI [1.08, 1.61]) compared to phacoemulsification alone (mean reduction=0.36, 95% CI [0.06, 0.66]). Funnel plots suggested the absence of publication bias. CONCLUSION: Both phacoemulsification alone or combined with KDB goniotomy result in a significant decrease in post-op IOP and topical glaucoma eye drops. The combination of these two procedures outperforms phacoemulsification alone in terms of both parameters.
