PURPOSETo review the characteristics and evolution of the fungal spectrum, and the risk factors causing fungal infection, and to make progress in diagnosing fungal infection after organ transplantation.

DATA SOURCESAn English-language literature search (MEDLINE 1990 - 2000) and bibliographic review of textbooks and review articles.

STUDY SELECTIONTwenty-three articles were selected from the literature that specifically addressed the stated purpose.

RESULTSFungal infections in organ transplant patients were generally divided into two types: (1) disseminated primary or reactivation infection with one of the geographically restricted systemic mycoses; (2) opportunistic infection by fungal species that rarely cause invasive infection in normal hosts. The risk factors of fungal infection after a transplant can be evaluated and predicted according to the organ recipient's conditions before, during and after the transplant. Progress in early diagnostic methods during the past 10 years has mainly revolved around two aspects, culture and non-culture.

CONCLUSIONSIt is important to undertake a systemic evaluation on the condition of the organ recipient before, during and after a transplant; should any risk factor for fungal infection be suspected, diagnosis should be made as early as possible by employing mycological techniques including culture and non-culture methods.

OBJECTIVETo investigate cachexia in hospitalized patients with digestive system cancer and evaluate its impact on clinical outcomes.

METHODSBy analyzing the clinical data of 5118 hospitalized patients with digestive system cancer in Zhongshan Hospital of Fudan University from January 2012 to December 2013, cachexia was investigated and clinical outcomes between cachexia patients and non-cachexia patients was compared.

RESULTSThe total cachexia rate of hospitalized patients with digestive system cancer was 15.7%(803/5118). The highest rate of cachexia was 34.0%(89/262) in patients with pancreatic cancer followed by gastric cancer 22.4%(261/1164), colon cancer 21.7%(146/672), and rectal cancer 20.1%(117/581). In cachexia group and non-cachexia group, the overall completion rate of radical resection was 67.1%(539/803) and 74.5%(3214/4315) respectively(P<0.05). Compared to the non-cachexia group, the cachexia group was associated with longer postoperative hospital stay [(11.5±6.2) d vs. (9.4±4.9) d, P<0.05], slower postoperative recovery of bowel function [(3.4±0.9) d vs. (3.2±0.8) d, P<0.05], longer postoperative time to intake of semifluid [(4.4±1.5) d vs. (3.9±1.1) d, P<0.05], and more postoperative complications within 28 days after radical surgery [8.9%(48/539) vs. 5.8%(186/3214), P<0.05]. After radical surgery, the ICU admission rate of the cachexia group [24.3%(131/539)] was higher than that of the non-cachexia group [20.1%(646/3214)] with significant difference(P<0.05). Compared to non-cachexia group, the reoperation rate [3.2%(17/539) vs. 1.5%(48/3214), P<0.05], ventilator support rate [8.0%(43/539)vs. 5.7%(184/3214), P<0.05] and mortality [2.4%(13/539) vs. 1.1%(35/3214), P<0.05] in the cachexia group were all significantly higher(all P<0.05).

CONCLUSIONSCachexia is commen in patients with digestive system cancer. Cachexia has significant adverse effects on clinical outcomes in hospitalized patients with digestive system cancer.

Previous studies have shown that postoperative cognitive dysfunction (POCD) is related to multiple factors including age, postoperative trauma, inflammation, postoperative pain, and anesthesia, among which postoperative pain is thought to play an important role in the development of POCD. This review summarizes the recent findings in the study of the role of postoperative pain in the pathogenesis of POCD in light of nerve injuries, neural remodeling and stress, and the progress in the prevention and treatment of POCD in elderly patients. It is of vital important to assess the postoperative pain and formulate adequate analgesic regimens for effective prevention and management of POCD to protect the brain functions of elderly patients.

Percutaneous vertebroplasty(PVP), among various other options,has become a mainstay in the management of osteoporotic compression vertebral fractures. The purpose of this article is to review complications arising from the procedure and describes methods to minimize them. Complications can be classified as mild,which may include a temporary increase in pain; transient hypotension and cement leakage in the intervertebral disc space or into paravertebral soft tissues, moderate, including infection; extravasation of cement into the foraminal or epidural space and severe such as cement leakage in the paravertebral veins, leading to pulmonary embolism, cardiac perforation, cerebral embolism or even death.

With the advancement of disease treatments, the number of patients undergoing surgery worldwide is increasing. However, many patients still experience severe perioperative complications. Perioperative hypotension is one of the common side effects during surgery. Physiologically, perioperative hypotension can lead to insufficient perfusion of important organs and result in acute and chronic irreversible organ injury, which cause serious consequences for the patient's postoperative hospitalization and even the long-term outcome. Therefore, in order to optimize perioperative circulation management and improve the quality of life for patients after surgery, it is of great importance to investigate the relationship between perioperative hypotension and postoperative myocardial injury, ischemic stroke, postoperative delirium, acute kidney injury, and postoperative mortality. Individualized circulation management and reasonable application of vasoactive drugs may be the key point to early prevention and correct treatment of perioperative hypotension, which is of great significance for reducing perioperative related morbidity and mortality and improving the prognosis for the surgical patients.

OBJECTIVE: To explore the influence of intraoperative urine volume on postoperative acute kidney injury (AKI) and the independent risk factors of AKI. METHODS: This was a retrospective cohort study recruiting patients who received selective pulmonary resection under general anesthesia in Peking University First Hospital from July, 2017 to June, 2019. The patients were divided into the AKI group and the control group according to whether they developed postoperative AKI or not. Firstly, univariate analysis was used to analyze the relationship between perioperative variables and postoperative AKI. Secondly, receiver operating characteristic (ROC) curve was used to explore the predictive value of intraoperative urine output for postoperative AKI. The nearest four cutoff values [with the interval of 0.1 mL/(kg·h)] at maximum Youden index were used as cutoff values of oliguria. Then univariate analysis was used to explore the relationship between oliguria defined by these four cutoff values and the risk of AKI. And the cutoff value with maximum OR was chosen as the threshold of oliguria in this study. Lastly, the variables with P < 0.10 in the univariate analysis were selected for inclusion in a multivariate Logistic model to analyze the independent predictors of postoperative AKI. RESULTS: A total of 1 393 patients were enrolled in the study. The incidence of postoperative AKI was 2.2%. ROC curve analysis showed that the area under curve (AUC) of intraoperative urine volume used for predicting postoperative AKI was 0.636 (P=0.009), and the cutoff value of oliguria was 0.785 mL/(kg·h) when Youden index was maximum (Youden index =0.234, sensitivity =48.4%, specificity =75.0%). Furthermore, 0.7, 0.8, 0.9, 1.0 mL/(kg·h) and the traditional cutoff value of 0.5 mL/(kg·h) were used to analyze the influence of oliguria on postoperative AKI. Univariate analysis showed that, when 0.8 mL/(kg·h) was selected as the threshold of oliguria, the patients with oliguria had the most significantly increased risk of AKI (AKI group 48.4% vs. control group 25.3%, OR=2.774, 95%CI 1.357－5.671, P=0.004). Multivariate regression analysis showed that intraoperative urine output < 0.8 mL/(kg·h) was one of the independent risk factors of postoperative AKI (OR=2.698, 95%CI 1.260－5.778, P=0.011). The other two were preoperative hemoglobin ≤120.0 g/L (OR=3.605, 95%CI 1.545－8.412, P=0.003) and preoperative estimated glomerular filtration rate < 30 mL/(min·1.73 m²) (OR=11.009, 95%CI 1.813－66.843, P=0.009). CONCLUSION Oliguria is an independent risk fact or of postoperative AKI after pulmonary resection, and urine volume < 0.8 mL/(kg·h) is a possible screening criterium.

OBJECTIVES: To analyze the risk factors for postoperative deep vein thrombosis (DVT) in neurosurgical patients to provide the basis for the prevention of postoperative DVT. METHODS: A total of 141 patients underwent neurosurgery were enrolled. Thrombelastography (TEG) test was performed before and at the end of surgery. According to whether there was DVT formation after operation, the patients were divided into a thrombosis group and a non-thrombosis group. -test and rank sum test were used to compare the general clinical characteristics of the 2 groups, such as age, gender, intraoperative blood loss, -dimer, intraoperative crystal input, colloid input, blood product transfusion, operation duration, length of postoperative hospitalization. The application of chi-square test and rank-sum test were used to compared TEG main test indicators such as R and K values between the 2 groups. Logistic regression was used to analyze the possible risk factors for postoperative DVT in neurosurgical patients. RESULTS: There were significant differences in postoperative TEG index R, clotting factor function, intraoperative blood loss, hypertension or not, length of postoperative hospital stay, and postoperative absolute bed time (all <0.05). Logistic regression analysis showed hypercoagulability, more intraoperative blood loss and longer postoperative absolute bed time were risk factors for DVT formation after craniotomy. CONCLUSIONS Hypercoagulability in postoperative TEG test of patients is an important risk factor for the formation of postoperative DVT after neurosurgery, which can predict the occurrence of postoperative DVT to some extent.
