Prophylactic cefazolin, given as a single 2 g (IV bolus 3-5 min before skin incision) was more than adequate in providing protective cefazolin levels for the duration of bariatric surgery. Cefazolin 2 g (IV dose bolus given just before skin incision) achieves protective adipose tissue levels (> MIC of MSSA) for the duration (usually < 4 h) of bariatric surgical procedures. In this study, cefazolin 2 g (IV bolus) provided protective adipose tissue levels for 4.8 h. Since cefazolin is a water soluble antibiotic (V = 0.2 L/Kg), penetration into adipose tissue is not V not dose-dependent. Extremely high-dosed cefazolin, i.e., 3 or 4 g is excessive and unnecessary for bariatric surgery prophylaxis. A single cefazolin 2 g preoperative dose also eliminates the need for intraoperative redosing at 4 h.
Objective. To explore the protective effects of hydrogen-rich saline on rats with smoke inhalation injury. Methods. 36 healthy male Sprague-Dawley rats were randomly divided into 3 groups (n = 12 per group): sham group (S), inhalation injury plus normal saline treatment group (I+NS), and inhalation injury plus hydrogen-rich saline treatment group (I+HS). 30 min after injury, normal saline and hydrogen-rich saline were injected intraperitoneally (5 mL/kg) in I+NS group and I+HS group, respectively. All rats were euthanized and blood and organ specimens were collected for determination 24 h after inhalation injury. Results. Tumor necrosis factor-alpha (TNF-α) levels, malondialdehyde (MDA) concentrations, nuclear factor kappa B (NF-κB) p65 expression, and apoptosis index (AI) in I+HS group were significantly decreased (P < 0.05), while superoxide dismutase (SOD) activities were increased compared with those in I+NS group; and a marked improvement in alveolar structure was also found after hydrogen-rich saline treatment. Conclusions. Hydrogen-rich saline treatment exerts protective effects in acute lung injury induced by inhalation injury, at least in part through the activation of anti-inflammatory and antioxidant pathways and inhibition of apoptosis.
Background: This study aimed to compare the safety and efficacy of the liver hanging maneuver (LHM) versus conventional approach for open hepatectomy.Methods: A comprehensive medical literature search was performed. Perioperative outcomes and long-term survival outcomes were reported. Subgroup analyses were conducted according to surgical approaches, modification of LHM, geographical region and indications for liver resection. Results: A total of 16 studies including 1109 patients were enrolled. The LHM was performed on 471 (37%) patients. The pooled outcomes showed hepatectomy with the LHM was associated with less estimated blood loss [standard mean difference (SMD): −0.77, P < 0.001], lower intraoperative transfusion rate [odds ratio (OR): 0.28, P = 0.003], less transection time (SMD: −0.68, P = 0.01), shorter duration of hospitalization (SMD:−0.19, P = 0.004), lower total complication rate (OR: 0.63, P = 0.008) and longer overall survival [hazard ration (HR): 0.70, P = 0.002] compared to conventional open hepatectomy.Subgroup analyses showed similar outcomes to overall analyses.
Conclusions:The present meta-analysis suggested that the LHM was a safe and feasible alternative to conventional open hepatectomy with better perioperative and long-term outcomes. It was unnecessary to combine the LHM with anterior approach (AA) in consideration of perioperative outcomes.
Background and objectiveExtra-articular manifestations (EAMs) are serious outcomes or complications of rheumatoid arthritis (RA) with increasing mortality and morbidity. The purpose was to explore the factors influencing EAMs, tissue-specific/systemic EAMs, and the concurrence of several EAMs.Patients and methodsIn total, 519 inpatients with RA were enrolled. The clinical characteristics, laboratory parameters, and medications of RA patients and the details of EAMs were recorded carefully. Differences between groups were examined by a Chi-square test, independent samples t test, one-way analysis of variance, Mann–Whitney U test, and Kruskal–Wallis H test. Binary and ordinal logistic regression analyses were performed to determine the relationship between influential factors and EAMs, tissue-specific/systemic EAMs, and the concurrence of several EAMs.ResultsThe morbidity of EAMs was 44.70%. Male sex, age, and traditional Chinese medicine (TCM) were independent influential factors of EAMs, and a number of statistically significant influence factors were found in the multivariate analysis of tissue-specific/systemic EAMs. Finally, age, CRP levels, number of RA-affected types of joints, and TCM were the factors that independently influenced the concurrence of several EAMs.ConclusionInfluential factors identified in this study could be recommended in clinical work, which is hopeful to decrease the morbidity and mortality of EAMs in RA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
