Solid organ transplant recipients may be at a high risk for SARS‐CoV‐2 infection and poor associated outcomes. We herein report our initial experience with solid organ transplant recipients with SARS‐CoV‐2 infection at two centers during the first 3 weeks of the outbreak in New York City. Baseline characteristics, clinical presentation, antiviral and immunosuppressive management were compared between patients with mild/moderate and severe disease (defined as ICU admission, intubation or death). Ninety patients were analyzed with a median age of 57 years. Forty‐six were kidney recipients, 17 lung, 13 liver, 9 heart, and 5 dual‐organ transplants. The most common presenting symptoms were fever (70%), cough (59%), and dyspnea (43%). Twenty‐two (24%) had mild, 41 (46%) moderate, and 27 (30%) severe disease. Among the 68 hospitalized patients, 12% required non‐rebreather and 35% required intubation. 91% received hydroxychloroquine, 66% azithromycin, 3% remdesivir, 21% tocilizumab, and 24% bolus steroids. Sixteen patients died (18% overall, 24% of hospitalized, 52% of ICU) and 37 (54%) were discharged. In this initial cohort, transplant recipients with COVID‐19 appear to have more severe outcomes, although testing limitations likely led to undercounting of mild/asymptomatic cases. As this outbreak unfolds, COVID‐19 has the potential to severely impact solid organ transplant recipients. 相似文献

The healing process in diabetic foot ulcer (DFU) is hindered by factors such as chronic inflammation, defects in fibroblast function, poor angiogenesis, and lack of cell migration. Recombinant human epidermal growth factor (rhEGF) has been shown to enhance extracellular matrix formation, cellular proliferation, and angiogenesis. Therefore, intralesional application of rhEGF in DFU could accelerate wound healing. Our objective was to determine the efficacy and safety of rhEGF in patients with DFU. A randomized, double‐blinded, placebo‐controlled study was conducted comparing a thrice‐per‐week intralesional application of rhEGF (75 μg) or placebo in patients with DFU for 8 weeks. The number of completely healed ulcers, size, and wound bed characteristics were evaluated to determine the efficacy of rhEGF. Adverse events were recorded and analyzed to establish its safety. A total of 34 patients were recruited for the study. After three dropouts, we were able to follow and analyze 16 patients in the placebo group and 15 patients in the rhEGF study to the end of the trial. Baseline testing showed that both groups were similar. Compared to the placebo group, more ulcers achieved complete healing in the rhEGF group (rhEGF, n = 4; placebo, n = 0; p = 0.033); ulcers in the rhEGF group decreased in area size (12.5 cm2 [rhEGF] vs. 5.2 cm2 [placebo]; p = 0.049); and more epithelial islands in the wound bed were present (28% vs. 3%; p = 0.025). Mild transitory dizziness was the only side effect that was more frequently noted in the rhEGF group. Our results showed that in patients with DFU who received standard care, intralesional rhEGF application resulted in complete healing in more patients, promoted the epithelialization of the wound bed, and significantly reduced the area of the DFU treated. Therefore, rhEGF resulted in better outcomes for patients suffering from DFU. 相似文献

Pressure ulcers (PU) are the source of multiple complications and even death. To our knowledge, there is no available data about PU prevalence in Mexico. The objective of this study was to determine the point prevalence of PU in three second‐level hospitals in Mexico. Every adult hospitalised patient was included in each hospital. Age, gender, hospitalisation ward, Braden score, and the number, location and stage of the ulcers encountered were recorded, as well as any pressure relief measures. In total, 294 patients were examined (127 were male); of these, 63 were considered to be at risk. The average age was 48·6 years. The overall prevalence of the PU was 17%. The service with the highest prevalence was the ICU. The most frequent stage was II (32%) and they were most commonly found in the sacrum (74%). The average Braden score of the patients with ulcers was 10, and 21·4% of the patients obtained moderate‐ to high‐risk Braden scores. Of them, 60·3% had ulcers and only 46% had any preventive measures. The prevalence of PU in three hospitals in Mexico is 17%. The most common stage is II and the most commonly affected site is the sacrum. Only 46% of patients with PU had at least one pressure release measure. 相似文献

Granulocyte Colony-stimulating Factor Supports Liver Regeneration in a Small-for-size Liver Remnant Mouse Model 总被引:1,自引:0,他引:1

Experimental partial hepatectomy of more than 80% of the liver weight bears an increased mortality in rodents, due to impaired
hepatic regeneration in small-for-size liver remnants. Granulocyte colony-stimulating factor (G-CSF) promotes progenitor cell
expansion and mobilization and also has immunomodulatory properties. The aim of this study was to determine the effect of
systemically administered G-CSF on liver regeneration and animal survival in a small-for-size liver remnant mouse model. Mice
were preconditioned daily for 5 days with subcutaneous injections of 5 μg G-CSF or aqua ad injectabile. Subsequently, 83%
partial hepatectomy was performed by resecting the median, the left, the caudate, and the right inferior hepatic lobes in
all animals. Daily sham or G-CSF injection was continued. Survival was significantly better in G-CSF-treated animals (P < 0.0001). At 36 and 48 h after microsurgical hepatic resection, markers of hepatic proliferation (Ki67, BrdU) were elevated
in G-CSF-treated mice compared to sham injected control animals (P < 0.0001) and dry liver weight was increased (P < 0.05). G-CSF conditioning might prove to be useful in patients with small-for-size liver remnants after extended hepatic
resections due to primary or secondary liver tumors or in the setting of split liver transplantation.
