Acute kidney injury (AKI) is a common complex condition associated with substantial morbidity, mortality and cost (NHS £1.02 billion per year for AKI related inpatient care). In 2013 NHS England in partnership with the UK Renal Registry, launched a National AKI Prevention Programme with the aim of improving the care of patients with AKI and recommended implementing patient safety alerts. AKI Clinical Nurse Specialists (AKI CNS) may provide a novel opportunity to improve outcomes for patients with AKI but there is limited understanding of the impact of their role. The aim of this audit is to compare the use of AKI electronic-alerts (e-alerts) combined with early response from a AKI CNS with usual care for patients admitted to the ward with AKI Stage 2 or 3 short-term outcomes Data were prospectively collected between 6th February 2017 to 7th March 2019 for all patients who had triggered a stage 2 or 3 AKI e-alert in a tertiary centre. Demographics, management details and laboratory data were extracted from hospital databases. Patients selected for AKI CNS review was based on clinical judgement. Outcomes for patients who received intervention from the AKI CNS were compared with those receiving usual care (clinical team received AKI e-alert prompt to complete the AKI care bundle). 417 patients were studied including 208 in the AKI CNS inpatient review group (AKI-CNS) and 209 in the usual care group (UCG). There were no demographics differences between groups. Significantly more patients in the AKI-CNS had AKI Stage 3 than the UCG (40% v 28%; P=0.01) and were more likely to have pre-existing chronic kidney disease (43 v 24%; P<0.0001). A comparable proportion of patients progressed from stage 2 to stage 3 AKI (20% vs 23%) when reviewed by an AKI CNS but those admitted to ICU had a significant shorter stay in ICU (mean: 3.5 vs 13.0 days; P=0.042) compared with UCG. Overall mortality, recovery from AKI, need for renal replacement therapy, time to recovery and length of stay were comparable in both groups despite those being reviewed by the AKI-CNS having more severe AKI and pre-existing CKD. AKI CNS care for patients who have more severe AKI and with underlying CKD appears to lead to comparable outcomes as patients with less severe AKI and comorbidities receiving usual care. In addition, those that received AKI CNS care had a significantly shorter length of stay in ICU.

Acute kidney injury in pregnancy (Pr-AKI) remains an important worldwide determinant of maternal and fetal morbidity and mortality. Furthermore, AKI in women of child-bearing age has recently been recognised to be associated with risk of pregnancy complications including pre-eclampsia. Thus, accurate identification of Pr-AKI in order to prevent immediate and long-term health complications is warranted in order to reduce both severity, immediate and long-term adverse outcomes and economic burden.

Patients receiving curative chemoradiation treatment (CRT) for head and neck cancer (HNC) undergo some of the most intensive treatments in oncology, resulting in immense physical and psychological symptoms. Integrated palliative care (PC) improves symptoms and coping in patients with advanced cancer, but has not been evaluated in patients with curable solid tumors. Thus, we are conducting the first pilot study of a collaborative palliative and oncology care intervention among patients receiving CRT to assess feasibility and acceptability.

BACKGROUND: Liver transplant recipients continue to have high perioperative resource utilization and prolonged length of stay despite improvements in perioperative care. Enhanced recovery pathways have been shown in other surgical populations to produce reductions in hospital resource utilization. METHODS: A prospective, observational study was performed to examine the effect of an enhanced recovery pathway for postoperative care after liver transplantation. Outcomes from patients undergoing liver transplantation from November 1, 2013, to October 31, 2014, managed by the pathway were compared to transplant recipients from the year before pathway implementation. Multivariable regression analysis was used to assess the association of the clinical pathway on clinical outcomes. RESULTS: The intervention and control groups included 141 and 106 patients, respectively. There were no demographic differences between the control and intervention group including no differences between the length of surgery and cold ischemic time. Median intensive care unit length of stay was reduced from 4.4 to 2.6 days (P < .001). The intervention group had a higher likelihood of earlier discharge (hazard ratio [95% CI], 2.01 [1.55–2.62]; P < .001), and a 69% and 65% lower odds of receiving a plasma (P < .001) or packed red blood cell (P < .001) transfusion. There was no significant effect on hospital mortality (P = .40), intensive care unit readmission rates (P = .75), or postoperative infections (urinary traction infections: P = .09; pneumonia: P = .27). CONCLUSIONS: An enhanced recovery pathway focused on milestone-based elements of intensive care unit management and predetermined management triggers including hemodynamic goals, fluid therapy, perioperative antibiotics, glycemic control, and standardized transfusion triggers led to reductions in intensive care unit length of stay without an increase in perioperative complications.

Osteoradionecrosis (ORN) has been defined in multiple ways; however, this diagnosis is generally made when exposed bone in a previously irradiated field is documented. This review of head and neck cancer patients who have been irradiated has incorporated the use of cone beam computed tomography (CBCT) scans to uncover ORN that is not visible on routine physical exam. Combining these radiographic findings with other characteristics in patients who have been diagnosed with ORN, there appear to be subsets of ORN. The charts of 45 patients with head and neck cancer who had received radiation therapy and been diagnosed with ORN were retrospectively reviewed. Specific characteristics looked at included the location of ORN, patient's sex, dose to area of breakdown of bone, finding on CBCT scan, and timing of diagnosis after radiation. Utilizing these 5 characteristics, it became clear that there were subsets of ORN that correlated with a patient's prognosis with respect to their ORN and the best approach in terms of managing this condition. Three subsets of patients with ORN were identified: (1) spontaneous ORN (SpO), (2) subclinical ORN (SubO), and (3) traumatic ORN (TO). Patients with SpO always developed ORN in the posterior aspect of the mylo-hyoid ridge of the mandible, were male, received between 6500 and 7000 centiGray, and occurred within 12 months after radiation. Patients with SubO did not have exposed bone but, instead, radiographically on CBCT scan, they had clear evidence of breakdown in their mandibular bone, this was not specific to males or females, on occasion they received less than 6500 centiGray, and occurred beyond 12 months out from radiation. Patients with TO developed ORN as a result of iatrogenic medical means (ie, following a biopsy in the previously irradiated field) or by an invasive dental procedure (ie, extraction or peridontal surgery in an area previously irradiated). Depending on the timing and management of one's treatment for ORN, patients with SpO had the best prognosis while those with TO had the worst. Prognosis of those with SubO was in between. This review suggests that rather than treating all patients with ORN the same way, there appears to be a benefit with placing them into 1 of 3 subsets of ORN: SpO, SubO, or TO. Doing so will help the treating radiation oncologist and dentist in caring for these individual's symptoms and counseling them in how best to deal with this potentially devastating complication of therapy both emotionally and psychologically.

BACKGROUND:Local hemostatic agents are important for the control of bleeding during liver resection when standard surgical techniques are insufficient. STUDY DESIGN:This was a multicenter, randomized, open-label study to compare fibrin sealant patch (FSP; TachoSil; Takeda Pharma A/S) with oxidized regenerated cellulose gauze (ORCG; Surgicel Original; Ethicon) for the secondary treatment of local bleeding after hepatic resection in adult and pediatric patients. Primary end point was the proportion of adult patients with intraoperative hemostasis at the target bleeding site within 3 minutes of application of treatment. RESULTS:Of 321 adult patients screened, 224 patients had minor to moderate bleeding from the hepatic resection area after primary hemostatic treatment and were intraoperatively randomized to FSP (n = 114) or ORCG (n = 110). Hemostasis within 3 minutes was achieved in 92 patients in the FSP group (80.7%) and 55 patients in the ORCG group (50.0%) (odds ratio = 4.87; 95% CI, 2.55-9.29; p < 0.001). The proportion of patients with hemostasis at 5 minutes was also higher in the FSP group (94.7% vs 76.4%; odds ratio = 6.24; 95% CI, 2.39-16.30; p < 0.001), and time to hemostasis was shorter (p < 0.001). At 10 minutes, hemostasis was achieved in all patients in the FSP group and 12 patients in the ORCG group (10.9%) had visible bleeding and required hemostatic rescue therapy. In pediatric patients, hemostasis at 3 minutes was achieved in 17 of 20 (85.0%) patients with FSP and 4 of 9 (44.4%) patients with ORCG. Both treatments were well tolerated in adults and children. CONCLUSIONS:The FSP (TachoSil) was safe and superior to ORCG (Surgicel Original) for achieving hemostasis in patients undergoing hepatic resection. ClinicalTrials.gov ID NCT01192022.

Background Corticosteroid use during post-transplant immunosuppression contributes to documented long-term complications in liver transplant recipients. However, the effects of steroids on post-transplant physical and mental health-related quality of life (HRQOL) have not been established. We aimed to test the association between steroid-based immunosuppression and post-transplant HRQOL in liver transplant recipients. Study Design We performed a retrospective analysis of prospective, longitudinal HRQOL measured using the Short Form 36 Health Survey physical and mental component summary scores, Beck Anxiety Inventory, and Center for Epidemiologic Studies Depression Scale. Steroid use (none, low [<10 mg/d], high [≥10 mg/d]) and temporally associated acute rejection (within previous 6 weeks, previous 7 to 12 weeks, and never or >12 weeks before HRQOL measurement) were determined at every post-transplant HRQOL data point. Linear mixed-effects models tested the effects of contemporaneous steroid use and dosing on post-transplant HRQOL. Results The sample included 186 adult liver transplant recipients (mean age 54 ± 8 years, 70% male) with pre- and at least 1 post-transplant HRQOL data point. Individual follow-up post-transplant averaged 21 ± 18 months (range 1 to 74 months). After controlling for pre-transplant HRQOL, time post-transplant, pre-transplant diagnosis group, and temporally associated episodes of rejection, post-transplant high-dose steroid use (≥10 mg/d) was associated with lower physical component summary (p < 0.001) and mental component summary (p = 0.049) scores and increased Beck Anxiety Inventory (p = 0.015) scores. Low-dose steroid use (<10 mg/d) was not associated with post-transplant HRQOL in any model (all p ≥ 0.28). Conclusions High-dose steroid use for post-transplant immunosuppression in liver transplant recipients was associated with reduced physical and mental HRQOL, and increased symptoms of anxiety. There was an association between better HRQOL and steroid reduction to <10 mg/d in liver transplant recipients during a broad follow-up period.

Lack of health insurance is associated with poorer outcomes for patients with cancers amenable to early detection. The effect of insurance status on hepatocellular carcinoma (HCC) presentation stage and treatment outcomes has not been examined. We examined the effect of health insurance status on stage of presentation, treatment strategies, and survival in patients with HCC.

Postoperative hemorrhage after orthotopic liver transplantation (OLT) may require early reoperative intervention. Previous studies have shown intraoperative transfusion requirement as a main determinant of reoperative intervention after OLT. The goal of this study was to develop an intraoperative hemorrhage model predicting need for reoperation after OLT. A single institution, retrospective review of adult primary OLT patients from January 2002 to 2008 was conducted. Multivariate logistical regression analysis was performed to identify predictors of reoperation due to postoperative hemorrhage. Secondary analysis was conducted on patients in the reoperation group managed with temporary open abdomen techniques. Four hundred and ten primary transplantations were performed with 59 patients (14.4%) requiring reoperation. The adjusted odds of reoperation when intraoperative blood loss (IBL) increases from 1.5 L to 10.0 L is 2.48 [95% confidence interval: (1.18, 5.31)]. IBL of 10.0 L predicts a 19.4 per cent probability of reoperation. Patients managed with open abdomen (n = 8) exhibited a significant IBL difference (16.0 L vs 6.0 L, P < 0.001) when compared with the closed abdomen cohort. Our results indicate that intraoperative blood loss is the primary predictor of reoperation after OLT and provide a hemorrhage threshold to guide postoperative management of complicated OLT patients.

Background. Recent studies suggest that obesity does not affect survival after liver transplantation. Overweight and obesity, however, impair health-related quality of life (HRQOL) in patients with chronic illnesses. We tested the effect of pretransplant body weight on HRQOL in liver transplant recipients.Methods. Prospective, longitudinal HRQOL data were collected using the SF-36 health survey. Pretransplant body weight was stratified based on body mass index (BMI), as follows: normal (18.5-24.9), overweight (25.0-29.9), and obese (>= 30.0). Linear mixed-effects models were used to test the effects Pretransplant BMI category on the trajectory of HRQOL after liver transplantation.Results. The sample included 154 adults who underwent liver transplantation. Thirty-one percent had normal BMI, 41% were overweight, and 28% were obese pretransplant. The mean pretransplant physical HRQOL did not differ 1, BMI group (P >= .697). Physical and mental HRQOL improved (P < .001) in all groups after transplantation, but the rate of improvement in physical HRQOL was significantly greater during the first year posttransplant in the normal BMI compared with the overweight and obese patients (P <= .032). There was no effect of BMI on the rate of improvement in menial HRQOL.Conclusion. Excess pretransplant body weight hinders the rate of improvement in physical quality of life during the first year after liver transplantation. (Surgery 2009,146:174-80.)

Despite randomized trials showing no benefit, drain use after open cholecystectomy continues, perhaps as a result of more complicated patient presentation. We examined the reasons for drain use in patients undergoing open cholecystectomy and evaluated the effect of drain placement on surgical outcomes.

Iatrogenic porta hepatis transection is a rare but devastating surgical complication. There are no systematic studies examining the best treatment strategy in patients with this injury. We report two cases of transection of all three portal structures, one during an open right adrenalectomy and another during a laparoscopic cholecystectomy, both of which were transferred to our tertiary care center hours postinjury. Diagnostic imaging and exploration revealed nonsalvageable livers, and both patients underwent total hepatectomies and portocaval shunting. Donor livers were available 12 to 20 hours after United Network for Organ Sharing Status 1 listing and both patients survived their postoperative course with 2- and 6-year follow up to date. Two-stage total hepatectomy with portocaval shunting followed by liver transplantation should be considered for patients presenting with porta hepatis transection.

INTRODUCTIONSeveral methods for hepatic parenchymal division exist. The primary aim was to assess differences in postoperative bile leaks, operative blood loss, and margin status between three transection methods: crush/clamp (CC), stapler (SP), or dissecting sealer (DS).METHODSA single institution, retrospective cohort study was performed on data collected over a three-year period in patients undergoing elective liver resection using the CC, SP, or DS. Patients were excluded if multiple methods of transection were used or for intraoperative death. The association of bile leak with transection type was assessed. A logistic regression model was tested to assess if blood loss was associated with the covariates of transection method, use of portal inflow occlusion, extent of liver resection, and other concurrent major operations.RESULTSAnalyses included 141 patients. The stapler method was quicker than the other methods (p=0.01). The risk of postoperative bile leak was no different between CC, SP, and DS transection methods (p=0.23). There was no difference in mean blood loss or transfusions; however, hepatectomies performed with DS were associated with an increased risk of blood loss > or = 1000 mL compared to CC (p=0.04). There were no differences in mean surgical margin between the three methods.CONCLUSIONThe risk of bile leaks was not different between the three methods. While mean blood loss was similar, hepatectomy performed with the DS was associated with an increased risk of having operative blood loss > or = 1000 mL compared to CC. Margins were equal by all methods. The stapler method was quicker.

INTRODUCTION:Tumor extent (T stage) and lymph node involvement (N stage) have a known combined negative effect on survival in patients with gallbladder adenocarcinoma, but the independent effects of these factors have been less well described. We investigated whether T stage and N stage independently predict survival after surgery for gallbladder adenocarcinoma.METHODS:We queried the Surveillance, Epidemiology and End Results database for patients treated with surgical resection for gallbladder adenocarcinoma between 1988 and 2004. Cases were stratified by disease severity based on tumor extent and nodal involvement. Kaplan-Meier and Cox regression methods were used to test the effect of disease severity and to develop multivariate models of the effects of demographic and clinical covariates on survival. Univariate and multivariate models were tested in the entire cohort and in a subsample with pathologically confirmed lymph node status.RESULTS:Four thousand and forty-eight patients who survived the immediate perioperative period comprised the full cohort. The subsample with pathologically confirmed lymph node status included 1298 patients. Age, gender, radiation treatment, tumor grade, tumor extent and lymph node status had statistically significant independent effects on survival in both models (all p<0.03). After accounting for T by N stage interactions, both tumor extent (1.21 < or = HR < or = 3.81, all p < or = 0.005) and lymph node involvement (1.80 < or = HR < or = 2.84, p<0.001) had independent effects on survival.CONCLUSIONS:Tumor extent and lymph node metastases are independent predictors of survival after surgical resection for gallbladder adenocarcinoma. Tumor penetration of the gallbladder wall and pathologically confirmed lymph node involvement each carry poor prognosis.

BACKGROUND:The purpose of this study was to develop a prognostic system applicable to patients with hepatic metastasis from colorectal cancer in whom extrahepatic disease was excluded by preoperative PET with [(18)F]fluoro-2-deoxy-D-glucose (FDG-PET). Data from two institutions were analyzed separately and together to improve general applicability of results.STUDY DESIGN:Data were analyzed for 285 consecutive patients undergoing liver resection for colorectal metastases from 1995 to 2005 at 2 institutions routinely using preoperative FDG-PET with. Fifteen clinicopathologic variables of the primary and secondary tumors were examined to identify factors predictive of survival.RESULTS:Outcomes were correlated with poorly differentiated tumor grade in both data sets. Because patients with poorly differentiated tumors comprised a small proportion (16%) of the population, patients with well-differentiated or moderately differentiated tumors were analyzed independently. In this subgroup, positive lymph node status in the primary colorectal tumor resection specimen was the only characteristic that predicted survival of patients in both institutions. Consequently, patients were sorted into three prognostic categories: poor tumor differentiation; well-differentiated or moderately differentiated tumors and node positive; and well-differentiated or moderately differentiated tumors and node negative. These groups had significantly different overall survival on Kaplan-Meier analysis (p=0.0014).CONCLUSIONS:In patients with colorectal liver metastases staged with FDG-PET with overall survival can be predicted directly from data in the pathology report of the colorectal primary tumor. This study also indicates the need for new molecular tumor markers of prognosis to complement clinicopathologic markers if the goal of prediction of outcomes in individual patients is to be reached.

Thymoglobulin (R) (Genzyme, Cambridge, MA) is an antithymocyte globulin preparation used for induction immunosuppression therapy in solid organ transplantation. It is being utilized with increasing frequency in orthotopic liver transplantation (OLT) in an effort to minimize or delay the use of calcineurin inhibitors due to their inherent nephrotoxicity. Experience with thymoglobulin in OLT remains limited. We report a case of serum sickness in a patient who received thymoglobulin following OLT. The patient experienced intermittent fevers, polyarthralgia, and acute renal failure 9 days after completion of thymoglobulin administration. The patient's symptoms resolved rapidly and completely with a course of intravenous steroids. We review a set of diagnostic criteria for serum sickness and emphasize the importance of early recognition of the process. Early treatment of serum sickness with steroids or plasmapheresis is highly effective and can reduce unnecessary morbidity from this unusual sequela of induction immunosuppression with antithymocyte globulin.
