Article Abstract
Unlabelled: Our objective was to compare outcomes following combined versus isolated resections for metastatic colorectal cancer and/or liver metastases using a large, contemporary national database.
Background: Controversy persists regarding optimal timing of resections in patients with synchronous colorectal liver metastases.
Methods: We analyzed 11,814 patients with disseminated colorectal cancer and/or liver metastases who underwent isolated colon, rectal, or liver resections (CRs, RRs, or LRs) or combined colon/liver or rectal/liver resections (CCLRs or CRLRs) in the National Surgical Quality Improvement Program Participant Use File (2011-2015). We examined associations between resection type and outcomes using univariate/multivariate analyses and used propensity adjustment to account for nonrandom receipt of isolated versus combined resections.
Results: Two thousand four hundred thirty-seven (20.6%); 2108 (17.8%); and 6243 (52.8%) patients underwent isolated CR, RR, or LR; 557 (4.7%) and 469 (4.0%) underwent CCLR or CRLR. Three thousand three hundred ninety-five patients (28.7%) had serious complications (SCs). One hundred forty patients (1.2%) died, of which 113 (80.7%) were failure to rescue (FTR). One thousand three hundred eighty-six (11.7%) patients experienced unplanned readmission. After propensity adjustment and controlling for procedural complexity, wound class, and operation year, CCLR/CRLR was independently associated with increased risk of SC, as well as readmission (compared with LR). CCLR was also independently associated with increased risk of FTR and death (compared with LR).
Conclusions: Combined resection uniformly confers increased risk of SC and increased risk of mortality after CCLR; addition of colorectal to LR increases risk of readmission. Combined resections are less safe, and potentially more costly, than isolated resections. Effective strategies to prevent SC after combined resections are warranted.

Hyaluronic Acid-Based Self-Healing Hydrogels for Diabetic Wound Healing.

Diabetic wounds, particularly diabetic foot ulcers (DFUs), are significant threats to human well-being due to their impaired healing from poor circulation and high blood sugar, increased risk of infection and potential for severe complications like amputation, all compounded by peripheral neuropathy and chronic inflammation. Most therapies and dressings for DFUs focus on one symptom at a time, however, multifunctional smart self-healing hydrogels can withstand multifactorial motional diabetic wounds. Motional wounds are easy-to-split wounds that experience tension, compression, and movement caused by stress now and then.

Aim: The prognosis of masked hypertension is controversial. The aims of this meta-analysis were to determine the global prevalence of masked hypertension and to better understand its association with the risk of cardiorenal comorbidities and all-cause mortality.
Methods: We searched the PubMed, Embase (OVID), The Cochrane Library, WanFang Data, and CNKI databases for relevant studies published from inception until January 15, 2024.
A Pooled Pharmacokinetic Analysis for Piperacillin/Tazobactam Across Different Patient Populations: From Premature Infants to the Elderly.
Clin Pharmacokinet
December 2024
Department of Anesthesiology, University of Groningen, University Medical Center Groningen, P. O. Box 30001, 9700 RB, Groningen, The Netherlands.
Background And Objectives: The pharmacokinetics (PK) of piperacillin/tazobactam (PIP/TAZ) is highly variable across different patient populations and there are controversies regarding non-linear elimination as well as the fraction unbound of PIP (f). This has led to a plethora of subgroup-specific models, increasing the risk of misusing published models when optimising dosing regimens. In this study, we aimed to develop a single model to simultaneously describe the PK of PIP/TAZ in diverse patient populations and evaluate the current dosing recommendations by predicting the PK/pharmacodynamics (PD) target attainment throughout life.
