The effects of anastomoses between anterior and posterior circulation on postoperative prognosis of patients with moyamoya disease.

BACKGROUND: Moyamoya disease (MMD) is a chronic ischemic cerebrovascular disease. Collateral circulation in MMD has emerged as a research focus. Our aims were to assess the impact of anastomoses between the anterior and posterior circulations on the prognosis of MMD patients. METHODS: We reviewed the preoperative digital subtraction angiography images of patients with MMD who underwent revascularization surgery at our hospital between March 2014 and May 2020 and divided the patients into two groups: those with anastomoses (PtoA group) and those without anastomoses (non-PtoA group). The differences in follow-up (more than 6 months) collateral vessel establishment (Matsushima grade) and the modified Rankin Scale (mRS) were compared between the two groups as well as between the patients with different degrees of anastomoses. The early complications following revascularization were also compared between the two groups. RESULTS: This study included 104 patients with MMD, of which 38 were non-PtoA and 66 were PtoA. There were no significant differences in Matsushima score (P = 0.252) and mRS score (P = 0.066) between the two groups. In addition, Matsushima score (P = 0.243) and mRS score (P = 0.360) did not differ significantly between patients with different degrees of anastomoses. However, the non-PtoA group had a significantly higher rate of cerebral hyperperfusion syndrome (CHS) than the PtoA group (34.2% vs 16.7%, P = 0.041). CONCLUSION: MMD patients without anastomoses between anterior and posterior circulations preoperatively should be vigilant of the occurrence of CHS in the early stages after revascularization.

A rare complication of leukostasis with AML M4 patient: Microcirculatory dysfunction of upper extremities.

BACKGROUND: In children with acute myeloid leukemia, the incidence of hyperleukocytosis is 5-33%. Patients with AML and hyperleukocytosis have a higher early mortality rate than patients with nonhyperleukocytic AML because of the increased risk of severe pulmonary and neurologic complications. Leukapheresis provides rapid cytoreduction and reduces early mortality rates. CASE PRESENTATION: In this report, we present a case with microcirculatory failure of upper extremities as a rare symptom of hyperleukocytic AML M4 at initial presentation. CONCLUSIONS: Early diagnosis and treatment of patients with AML admitted to emergency services with these symptoms is too important to prevent from loss of extremities. Most of the complications of hyperleukocytosis can be reversible with early treatment.

Low postoperative complication rate with high survival rate and good clinical outcome 9 years after autologous chondrocyte transplantation of the knee joint.

PURPOSE: To investigate postoperative complications and associated risk factors for failure following autologous chondrocyte transplantation ("ACT") as well as its long-term survival and clinical function. It was hypothesized that ACT is a safe technique for cartilage repair with a low incidence of postoperative complications and rare rates of revision surgery combined with a high long-term survival and good to excellent clinical outcome in long-term-follow-up. METHODS: All patients undergoing ACT-Cs of the knee joint between 2006 and 2012 at the author's institution were included in this retrospective study. Concomitant procedures had been performed if necessary. Early postoperative complications, revision surgeries, failure and risk factors for those events were evaluated 6 months after the surgery. Long-term clinical outcome was assessed using the Lysholm Score, the Tegner Score, a 10-grade scale for satisfaction and the Visual Analogue Scale (VAS) at a minimum follow-up of 9 years postoperatively. Long-term survival was calculated using revision surgeries, clinical failures and conversion procedures to create a Kaplan-Meier analysis. A subgroup analysis for different defect locations was performed. 139 patients were included in this study (27% female/ 73%male; age 26.7 [21.7; 35.2] years). The median defect size was 4.0 [3.0; 6.0] cm2 (40% medial femoral condyle (MFC), 17% lateral femoral condyle (LFC), 36% patella, 19% trochlea). 97 (70%) of the patients had undergone previous surgery and 84 (60%) underwent concomitant procedures. RESULTS: Postoperatively, 8% of patients had complications (4% bleeding, 2% arthrofibrosis, 2% infection), 7% of patients needed revision surgery. 12% of patients had a prolonged deficit in ROM, that did not require revision surgery. No significant difference in terms of complications was found between the patellofemoral and femorotibial group. Patients demonstrated good patient reported long-term outcomes 9-15 years after the index surgery (Tegner: 4.7 ± 1.8; VAS: 2.4 ± 2.1; Lysholm: 80 ± 14; satisfaction with operation: 7.3 ± 1.9). Survival rates were 88% at 9 years, 85% at 11 years, and 85% at 13 years after the index procedure. Reasons for failure included debridement of ACT (n = 4; 5%), revision ACT (n = 3, 3%), conversion to total knee arthroplasty (n = 3, 3%) and conversion to High tibial osteotomy (HTO) (n = 1; 1%)). CONCLUSION: The present study indicates ACT as an effective treatment option for femorotibial- as well as patellofemoral cartilage defects with a high long-term survival and low conversion rate as well as good long-term results regarding knee function and satisfaction. Postoperative complications needing revision surgery are rare. Prolongated deficits of range of motion appear frequently up to six months especially in patellofemoral defects, but can often be successfully addressed by intensified physiotherapy without requiring an arthrolysis. LEVEL OF EVIDENCE: Level III.

Risk factors and outcomes of bile leak after laparoscopic surgery for congenital biliary dilatation.

PURPOSE: One of the main causes of stricture at hepaticojejunostomy site after surgery for congenital biliary dilatation is inflammation or infection associated with bile leak. The aim of this study was to determine the risk factors and outcomes of bile leak after laparoscopic surgery. METHODS: We retrospectively reviewed the demographics and outcomes of patients who underwent laparoscopic surgery for congenital biliary dilatation between September 2013 and December 2019. Data from patients with bile leak were compared to data from patients without bile leak. RESULTS: Fourteen of 78 patients had bile leak. Hepatic duct diameter at anastomosis was the only risk factor of bile leak. Patients with the diameter ≤ 10 mm had higher incidence of bile leak than in patients with the diameter > 10 mm (P = 0.0023). Among them, bile leak occurred more frequently in patients operated on by non-qualified surgeons based on the Japan Society for Endoscopic Surgery endoscopic surgical skill qualification system than by qualified surgeons (P = 0.027). However, none of the patients with bile leak developed anastomotic stricture afterwards. CONCLUSION: Although good technical skill is necessary to avoid bile leak in narrow hepatic duct cases (≤ 10 mm), slight bile leak may not result in anastomotic stricture.

The frequency of early stomal, peristomal and skin complications.

BACKGROUND: The incidence of early complications after stoma formation (within 30 days of surgery) is difficult to determine and has been reported to be in a range of 3%-82%. AIM: The aim of this study was to analyse the onset of stomal, peristomal and skin complications one month (30 days) after ostomy creation. METHOD: This review analysed enteral stoma therapy nurse reports on patients who had an ostomy created between January 2016 and December 2020. FINDINGS: Complications were analysed according to ostomy type: colostomy, ileostomy and urostomy. There were 1292 incidences of complications: skin complications were the most common (26%), and abscess the least common (0%). CONCLUSION: A majority (63%) of patients experienced at least one or more complications within 30 days of surgery. Haemorrhage was reported as a complication (2%) but the authors found no data on its incidence in the literature. In addition to early complications, late complications were detected.

Incidence, Risk Factors, and Outcomes of Idiopathic Pneumonia Syndrome after Allogeneic Hematopoietic Cell Transplantation.

Our current knowledge of idiopathic pneumonia syndrome (IPS) predates improved specificity in the diagnosis of IPS and advances in hematopoietic cell transplantation (HCT) and critical care practices. In this study, we describe and update the incidence, risk factors, and outcomes of IPS. We performed a retrospective cohort study of all adults who underwent allogeneic HCT at the Fred Hutchinson Cancer Research Center between 2006 and 2013 (n = 1829). IPS was defined using the National Heart, Lung, and Blood Institute consensus definition: multilobar airspace opacities on chest imaging, absence of lower respiratory tract infection, and hypoxemia. We described IPS incidence and mortality within 120 and 365 days after HCT. We examined conditioning intensity (nonmyeloablative versus myeloablative with high-dose total body irradiation [TBI] versus myeloablative with low-dose TBI) as an IPS risk factor in a time-to-event analysis using Cox models, controlled for age at transplant, HLA matching, stem cell source, and pretransplant Lung function Score (a combined measure of impairment in Forced Expiratory Volume in the first second (FEV1) and Diffusion capacity for carbon monoxide (DLCO)). Among 1829 HCT recipients, 67 fulfilled IPS criteria within 120 days (3.7%). Individuals who developed IPS were more likely to be black/non-Hispanic versus other racial groups and have severe pulmonary impairment but were otherwise similar to participants without IPS. In adjusted models, myeloablative conditioning with high-dose TBI was associated with increased risk of IPS (hazard ratio, 2.5; 95% confidence interval, 1.2 to 5.2). Thirty-one patients (46.3%) with IPS died within the first 120 days of HCT and 47 patients (70.1%) died within 365 days of HCT. In contrast, among the 1762 patients who did not acquire IPS in the first 120 days, 204 (11.6%) died within 120 days of HCT and 510 (29.9%) died within 365 days of HCT. Our findings suggest that although the incidence of IPS may be declining, it remains associated with post-transplant mortality. Future study should focus on early detection and identifying pathologic mediators of IPS to facilitate timely, targeted therapies for those most susceptible to lung injury post-HCT.

Biomarkers of Unfavorable Outcome in Acute Ischemic Stroke Patients with Successful Recanalization by Endovascular Thrombectomy.

BACKGROUND: We aimed to identify plasma markers of unfavorable outcomes for patients with acute ischemic stroke (AIS) after recanalization by endovascular thrombectomy (EVT). METHODS: From November 2017 to May 2019, we prospectively collected 61 AIS patients due to anterior large vessel occlusion who achieved recanalization by EVT. Plasma samples were obtained between 18 and 24 h after recanalization. Unfavorable outcomes included futile recanalization at 90 days and overall early complications within 7 days after EVT. RESULTS: After adjustment for age and initial National Institute of Health Stroke Scale (NIHSS), matrix metalloproteinase-9 (MMP-9), tenascin-C, thioredoxin, ADAMTS13, and gelsolin were independently associated with both futile recanalization and overall early complications significantly (all p < 0.05), while C-reactive protein (CRP) was independently associated with overall early complications (p = 0.031) but at the limit of significance for futile recanalization (p = 0.051). The baseline clinical model (BCM) (including age and initial NIHSS) demonstrated discriminating ability to indicate futile recanalization (area under the curve [AUC] 0.807, 95% confidence interval [CI] 0.693-0.921) and overall early complications (AUC 0.749, 95% CI 0.611-0.887). BCM+MMP-9+thioredoxin enhanced discrimination (AUC 0.908, 95% CI 0.839-0.978, p = 0.043) and reclassification (net reclassification improvement [NRI] 67.2%, p < 0.001) to indicate futile recanalization. With respect to overall early complications, BCM+MMP-9+tenascin-C, BCM+MMP-9+CRP, BCM+MMP-9+ADAMTS13, BCM+tenascin-C+ADAMTS13, and BCM+CRP+ADAMTS13, all improved discrimination (AUC [95% CI]: 0.868 [0.766-0.970], 0.882 [0.773-0.990], 0.886 [0.788-0.984], 0.880 [0.783-0.977], and 0.863 [0.764-0.962], respectively, all p < 0.05 by the DeLong method) and reclassification (NRI 59.1%, 71.8%, 51.1%, 67.4%, and 38.3%, respectively, all p < 0.05). CONCLUSIONS: The increased levels of MMP-9, tenascin-C, CRP, thioredoxin, and decreased levels of ADAMTS13 and gelsolin were independent predictors of futile recanalization in AIS patients after recanalization by EVT.

Impact of Diabetes on 30-Day Complications in Mastectomy and Implant-Based Breast Reconstruction.

BACKGROUND: Diabetic patients are known to be at increased risk of postoperative complications after multiple types of surgery. However, conflicting evidence exists regarding the association between diabetes and wound complications in mastectomy and breast reconstruction. This study evaluates the impact of diabetes on surgical outcomes after mastectomy procedures and implant-based breast reconstruction. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database review from 2010 to 2015 identified patients undergoing total, partial, or subcutaneous mastectomy, as well as immediate or delayed implant reconstruction. Primary outcomes included postoperative wound complications and implant failure. Preoperative variables and outcomes were compared between diabetic and nondiabetic patients. Multivariate regression was used to control for confounders. RESULTS: The following groups were identified: partial (n = 52,583), total (n = 41,540), and subcutaneous mastectomy (n = 3145), as well as immediate (n = 4663) and delayed (n = 4279) implant reconstruction. Diabetes was associated with higher rates of superficial incisional surgical site infection (SSI) in partial mastectomy (odds ratio [OR] = 8.66; P = 0.03). Diabetes was also associated with higher rates of deep incisional SSI (OR = 1.61; P = 0.01) in subcutaneous mastectomy and both superficial (OR = 1.56; P = 0.04) and deep incisional SSI (OR = 2.07; P = 0.04) in total mastectomy. Diabetes was not associated with any wound complications in immediate reconstruction but was associated with higher rates of superficial incisional SSI (OR = 17.46; P < 0.001) in the delayed reconstruction group. There was no association with implant failure in either group. CONCLUSIONS: Evaluation of the largest national cohort of mastectomy and implant reconstructive procedures suggests that diabetic patients are at significantly increased risk of 30-d postoperative infectious wound complications but present no difference in rates of early implant failure.

[Poly Implant Prothèse (PIP®) incidence of complications in breast reconstructive surgery: A retrospective comparative analysis]. / Poly Implant Prothèse (PIP®) et incidence des complications en reconstruction mammaire: une étude rétrospective contrôlée.

INTRODUCTION: On 29 March 2010, the Poly Implant Prothèse (PIP(®)) breast prosthesis was withdrawn from the market by the ANSM. In this study we review our experience with PIP(®) implants in breast reconstruction. We compare our complications with other types of breast implants used during the same period at our institution. PATIENTS AND METHOD: This is a retrospective study conducted at the Hospital René Huguenin of the Institut Curie (Paris, France). It includes 327 prostheses, from 268 patients who underwent surgery for breast reconstruction between February 2008 and February 2012: 69 PIP(®) (Group 1), 82 Mentor(®) (Group 2) and 179 Allergan(®) (Group 3). The objective of the study was to compare the rates of early and late complications for each prosthesis. Our results are compared with the current literature. RESULTS: With regard to the rate of early complications (hematoma, infection, seroma, wound dehiscence), no difference was observed between the three groups (P not significant). However, the study found that 100% of the 13 PIP(®) implants with early complications required surgical revision. There were too few late complications (capsular contracture, prosthetic rupture) in our cohort to allow statistical comparison between the three groups (P not significant). We compare our results with the current literature. CONCLUSION: This study highlights the lack of significant difference in the occurrence of early adverse events between the three groups of implants. This may explain the time taken for surgeons to become aware there was a problem with the PIP(®) implants. The low rate of late complications in our series does not allow statistical analysis between the three groups of implants.

Risk factors for early complications following arthroplasty in elderly patients with a femoral neck fracture.

BACKGROUND: Early complications after arthroplasty for geriatric femoral neck fractures are known to negatively affect postoperative recovery and increase postoperative mortality. Identifying risk factors associated with early complications after arthroplasty may offer an opportunity to address and prevent these complications in many patients. OBJECTIVE: To evaluate preoperative risk factors for early complications after arthroplasty in elderly patients with a femoral neck fracture. METHODS: 119 elderly patients with femoral neck fractures who had been treated with arthroplasty (hemiarthroplasty or total hip arthroplasty) between December 2015 and December 2018 were retrospectively analysed. Early complications were defined as any complications that did not exist preoperatively, and occurred during hospital stay after arthroplasty Preoperative clinical, epidemiological and laboratory data were collected. Binary univariable and multivariable logistic regression analysis were applied to identify predictors of early complications after arthroplasty for geriatric femoral neck fractures. RESULTS: Median age of all patients was 80.0 (IQR 74.0-84.0) years. We identified 28 (23.5%) early complications after arthroplasty. Univariable logistic regression analysis found that preoperative body mass index (BMI p= 0.031), C-reactive protein (CRP p= 0.017) and serum Albumin (p= 0.006) were potential risk factors for early complications. Then preoperative BMI, CRP and serum Albumin were stratified and used for multivariable logistic regression analysis The multivariate logistic regression analysis showed that preoperative higher BMI (⩾ 28 kg/m2; OR 10.440; 95% CI 2.674-41.170; p= 0.001) and lower serum Albumin (⩽ 35 g/L; OR 3.933; 95% CI 1.509-10.800; p= 0.006) were independent risk factors for early complications after arthroplasty in geriatric femoral neck fractures. However, preoperative higher CRP levels (> 10 mg/L; OR 1.139; 95% CI 1034-1428; p= 0.833) was found to be not an independent risk factor for early complications. CONCLUSION: Our results demonstrate that obesity and hypoalbuminemia are independent predictors for early complications during hospital stay after arthroplasty, which should be meticulously noted to minimize these risk factors in geriatric femoral neck fractures.

Hyperleukocytosis in Childhood Acute Leukemia: Early Complications and Survival Outcomes.

Hyperleukocytosis and extreme hyperleukocytosis, defined as initial white blood cell counts greater than 100 × 109/L and 200 × 109/L, respectively, have been associated with unfavorable outcomes. This study aimed to determine the early complications and survival outcomes of childhood leukemia patients with hyperleukocytosis. The medical records of 690 children newly diagnosed with acute leukemia between January 1998 and December 2017 were retrospectively reviewed. The Kaplan-Meier method and log-rank test were used to assess and compare the survival outcomes. Multivariate Cox proportional hazards regression was used to determine associated risk factors for overall survival. We found that 16.6% of 483 childhood acute lymphoblastic leukemia (ALL) patients and 20.3% of 207 childhood acute myeloid leukemia (AML) patients had hyperleukocytosis at diagnosis. ALL patients with hyperleukocytosis had more early complications than those without hyperleukocytosis (p < 0.05). Among the ALL group, the 5-year overall survival rate for those with hyperleukocytosis was significantly lower than for those without hyperleukocytosis (37.2% vs. 67.8%, p < 0.0001), while the difference was not statistically significant in the AML group (19.0% vs. 30.2%, respectively, p = 0.26). Hyperleukocytosis (hazard ratio [HR]: 2.04), extreme hyperleukocytosis (HR: 2.71), age less than 1 year (HR: 3.05), age greater than 10 years (HR: 1.64), and male sex (HR: 1.37) were independently associated with poorer overall survival in childhood ALL patients. Extreme hyperleukocytosis (HR: 2.63) and age less than 1 year (HR: 1.82) were independently associated with poorer overall survival in AML patients. Hyperleukocytosis was associated with adverse survival outcomes in childhood leukemia.

Using blood glucose and lactate levels for early detection of venous congestion following a free flap procedure for lower extremity open fractures.

PURPOSE: Gustilo-Anderson type IIIB and IIIC open fractures of the lower extremities require reconstruction of extensively injured soft tissues using a free flap; however, impaired blood flow through the flap is an early postoperative complication. To detect flap congestion due to venous thrombosis, blood glucose and lactate level measurements within the flap are taken to determine variations in these levels. We aimed to detect early-stage venous congestion and to perform salvage operations. METHODS: We included 22 limbs with lower leg and foot open fractures, with fracture sites covered using a free flap. A pinprick test was used to measure blood glucose and lactate levels. RESULTS: Of 7 and 15 congested and non-congested limbs, respectively, the 7 congested limbs had a mean flap blood glucose level immediately before salvage surgery of 3.8 ± 2.0 (7.4-1.8) mmol/L. The ratio to blood glucose levels in healthy fingertips was 0.6 ± 0.2 (0.8-0.3). Lactate levels increased to 13.3 ± 5.1 (9.4-22.8) mmol/L. The ratio of blood glucose levels in congested flaps and in healthy fingertips was significantly lower than that in non-congested flaps and in healthy fingertips (p = 0.0016). Lactate levels were significantly higher in patients with congestion (p = 0.0013). Salvage surgery was performed, thrombi were removed, and six limb flaps were viable. CONCLUSION: Flap blood glucose and lactate levels provide a quantitative method of evaluating blood flow and detecting flow abnormalities postoperatively, and are useful in detecting early congestion due to venous thrombosis.

Establishment of a prediction model for early and mid-term complications for patients undergoing catheter insertion for peritoneal dialysis.

OBJECTIVE: To investigate the factors involved in early and mid-term complications after catheter insertion for peritoneal dialysis and to establish prediction models. METHODS: A total of 158 patients with peritoneal dialysis in the Department of Nephrology of our hospital were retrospectively analyzed. General information, laboratory indices, early complications (within 1 month after the operation), mid-term complications (1-6 months after the operation), and other relevant data were recorded. Multivariate logistic regression analysis was performed to establish a prediction model of complications and generate a nomogram. Receiver operating characteristic (ROC) curve analysis was used to evaluate the efficacy of the model. RESULTS: Among the patients, 48 (30.8%) had early complications, which were mainly catheter-related complications, and 29 (18.4%) had mid-term complications, which were mainly abdominal infection and catheter migration. We constructed a prediction model for early complications (area under the curve = 0.697, 95% confidence interval: 0.609-0.785) and mid-term complications (area under the curve = 0.730, 95% confidence interval: 0.622-0.839). The sensitivity was 0.750 and 0.607, and the specificity was 0.589 and 0.765, respectively. CONCLUSIONS: Our prediction model has clinical significance for risk assessment of early and mid-term complications and prevention of complications after catheterization for peritoneal dialysis.

Frequency and Early Complications of Late Preterm Infants: A Descriptive Analysis from Two Secondary-care Hospitals of Karachi.

Introduction Globally, prematurity accounts for 12.7% of all live births while late preterm accounts for around three-fourth (73%) of these premature births. In Pakistan, the prevalence of prematurity is approximately 18.89%. Late preterm infants often have weight and size similar to some term infants, but they are still metabolically and physiologically immature. Hence, these infants, as compared to term infants, are at a higher risk of developing medical complications, which results in higher morbidity and mortality during the birth hospitalization. We aim to determine the frequency of early complications in late preterm infants during their stay at Aga Khan Secondary-care Hospitals, Karachi. Methods A prospective descriptive study was conducted via the nonprobability sampling technique from March 22, 2016, to March 22, 2017, at secondary-care hospitals of The Aga Khan University Hospital; The Aga Khan Hospital for Women, Karimabad, and The Aga Khan Hospital for Women and Children, Garden. All late-preterm infants, i.e. those born between the 340/7 through 366/7 weeks gestation were included in this study and observed for 72 hours after birth for early complications, including hypothermia, sepsis, hypoglycemia, respiratory distress, and hyperbilirubinemia. Descriptive analysis was done using SPSS Version 19.0 (IBM Corp., Armonk, NY, US) and frequency and percentages were calculated. Results Throughout the period of study, a total of 1696 infants were born in secondary-care hospitals, of which 86.67% (n=1470) were term and 13.3% (n=226) were preterm. Late preterm infants constituted 95.5% (n=217) of preterm births and 12.7% of all newborns delivered at study sites. Among them, respiratory distress was diagnosed in 23.5%, hyperbilirubinemia in 17.5%, hypoglycemia in 13.8%, sepsis in 9.2%, and hypothermia in 6%. Conclusion Late preterm neonates form the major subgroup of preterm infants delivered at secondary-care hospitals. They have a significant risk of morbidity and birth hospitalizations. We propose that late preterm infants, regardless of their physical dimensions, be given medical attention similar to all preterms.

Predictive value of liver damage for severe early complications and survival after heart transplantation: A retrospective analysis.

BACKGROUND: Hepatic dysfunction is often associated with advanced heart failure. Its impact on complications following heart transplantation is not well known. We studied the influence of preoperative hepatic dysfunction on the results of heart transplantation with a specific priority access for critical patients. METHODS: Consecutive heart transplantation patients were retrospectively analyzed at listing to detect predictive factors for early complications and survival following heart transplantation. RESULTS: Among heart transplant candidates (n=384), median age was 52 years, dilated and ischemic cardiopathies were present in 44% and 32%, respectively. Clinical ascites was present in 15.6% and median MELD score was 13. A temporary circulatory support and a national priority access were necessary in 14.8% and 35% respectively. Whereas 12% of the global cohort died on the waiting list, 321 patients were transplanted, 34.2% suffered from severe early complications, 26.3% needed extracorporeal membrane oxygenation in postoperative period, 27.7% died before 3 months with a 5-year survival rate of 56%. At listing, clinical ascites, and creatinine were independently associated with specific early complications i.e. primary graft dysfunction and septic shock respectively. Bilirubin level was also an independent marker of other early complications. Finally, need for postoperative circulatory support and postoperative 90-day mortality were strongly and exclusively associated with clinical ascites and creatinine at listing. In a subgroup analysis, we predicted more accurately the postoperative survival at 3 months by combining MELD score and ascites. CONCLUSION: At listing, hepatic and renal dysfunctions are independent risk factors that could predict severe early complications and mortality following heart transplantation in the most severe patients.

Direct costs of osteoporosis-related hip fractures: protocol for a cross-sectional analysis of a national database.

INTRODUCTION: It is estimated that Iran accounted for about 1% of hip fracture burden of the world in 2007, but these data are based on incomplete evidence. As the country's population is ageing, it is expected that a dramatic rise in hip fracture incidence will result. There is no single national study that accurately estimates the incidence of all hip fractures in the country or identifies the direct costs for affected patients. To help fill this gap, the current study has been designed to determine the incidence of hip fracture associated with osteoporosis in the Iranian population and to assess the direct costs involved. METHODS AND ANALYSIS: This is a cross-sectional analysis of 2 years of hospital admissions due to hip fracture in Iran from October 2014 to October 2016 using an electronic health record called SEPAS. SEPAS is a nationwide health information system established by Information Technology (IT) and the Statistics Department of the Ministry of Health. SEPAS has recorded more than 8.5 million inpatient hospitalizations since October 2014. Our study will identify reported hip fracture data in SEPAS among admitted adult hospital patients aged ≥50 in Iran. International Classification of Diseases ICD-9 and 10 will be used as diagnostic codes. Study factors are demographic data, types of fracture, types of treatment, duration of admission, early complications, in-hospital mortality and direct cost of fracture treatment. The accuracy of the SEPAS fracture data will be ascertained through a pilot study that compares the SEPAS data with the data directly extracted from medical records of the Shariati Hospital in Tehran during the study period. ETHICS AND DISSEMINATION: The study protocol was approved by the Ethics Committee of the National Institute for Medical Research Development of Iran. Dissemination plans include academic publications, conference presentations and social media.

Metabolic syndrome, obesity, and radical cystectomy complications: a clavien classification system-based analysis.

INTRODUCTION/BACKGROUND: The objective of this study was to evaluate the effect of MetS and its components on the early complications observed in patients treated with RC and urinary diversion. PATIENTS AND METHODS: We retrospectively analyzed 346 patients with bladder cancer undergoing RC with standard lymphadenectomy, according to the procedure suggested by the International Consultation on Bladder Cancer, and urinary diversion. All early complications within 90 days of surgery were recorded and collected according to the 10 Martin criteria and classified according to the established 5 grades of the modified Clavien classification system (CCS). MetS was defined according to the National Cholesterol Educational Program's Third Adult Treatment Panel. A binary logistic regression analysis was used to analyze MetS and, separately, its single components, as possible independent risk factors for high-grade complications. RESULTS: A total of 323 complications occurred in 231 of 346 patients (66.8%). The rates for low-grade (CCS I-II) and high-grade complications (CCS III-V), and mortality within 90 days (CCS V), were 80.8% (261 of 323), 19.2% (62 of 323), and 1.7% (6 of 346), respectively. At univariate analysis, MetS patients showed a higher rate of high-grade complications compared with patients without MetS (P < .001). At binary logistic regression analysis, MetS (OR, 1.3; P = .010), waist circumference (OR, 1.9; P = .022) and, only in single model, urinary diversion (OR, 1.3; P = .024) were independent risk factors for high-grade complications. CONCLUSION: RC is a major surgical procedure with a significant early complications rate, nevertheless, most are low-grade complications. MetS and, separately, waist circumference are associated with high-grade complications.

Complications after subpectoral biceps tenodesis using a dual suture anchor technique.

PURPOSE: A variety of fixation techniques for subpectoral biceps tenodeses have been described including interference screw and suture anchor fixation. Biomechanical data suggests that dual suture anchor fixation has equivalent strength compared to interference screw fixation. The purpose of the study is to determine the early complication rate after subpectoral biceps tenodesis utilizing a dual suture anchor technique. MATERIALS AND METHODS: A total of 103 open subpectoral biceps tenodeses were performed over a 3-year period using a dual suture anchor technique. There were 72 male and 31 female shoulders. The average age at the time of tenodesis was 45.5 years. 41 patients had a minimum of 6 months clinical follow-up (range, 6 to 45 months). The tenodesis was performed for biceps tendonitis, superior labral tears, biceps tendon subluxation, biceps tendon partial tears, and revisions of prior tenodeses. RESULTS: There were a total of 7 complications (7%) in the entire group. There were 4 superficial wound infections (4%). There were 2 temporary nerve palsies (2%) resulting from the interscalene block. One patient had persistent numbness of the ear and a second patient had a temporary phrenic nerve palsy resulting in respiratory dysfunction and hospital admission. One patient developed a pulmonary embolism requiring hospital admission and anticoagulation. There were no hematomas, wound dehiscences, peripheral nerve injuries, or ruptures. In the sub-group of patients with a minimum of 6 months clinical follow-up, the only complication was a single wound infection treated with oral antibiotics. CONCLUSIONS: Subpectoral biceps tenodesis utilizing a dual suture anchor technique has a low early complication rate with no ruptures or deep infections. The complication rate is comparable to those previously reported for interference screw subpectoral tenodesis and should be considered as a reasonable alternative to interference screw fixation. LEVEL OF EVIDENCE: Level IV-Retrospective Case Series.

Effects of Danshen Chuanxiongqin Injection Combined with Hyperbaric Oxygen on the Prevention of Early Complications of Acute Spinal Cord Injury / 中国药房

OBJECTIVE:To investigate the effects of Danshen chuanxiongqin injection combined with hyperbaric oxygen on the prevention of early complications in patients with acute spinal cord injury (ASCI).METHODS:A total of 89 ASCI patients were divided into control group (n=44) and combination group (n =45) according to random number table.Control group received routine symptomatic treatment combined with hyperbaric oxygen therapy.Combination group was additionally given Danshen chuanxiongqin intravenous injection 10 mL added into 250 mL 0.9％ Sodium chloride injection intravenously,bid,on the basis of control group.Both group was treated for 2 weeks.The changes of spinal cord function recovery index (Botsford score,FIM score),coagulation indexes [prothrombin time (PT),activated partial thromboplastin time (APTT)],hemodynamic indexes (high-shear blood viscosity,plasma viscosity,erythrocyte aggregation indexes) and inflammatory indexes [D-dimer (D-D),C reactive protein (CRP)] were compared between 2 groups before and after treatment.After 1 month of follow-up,the incidence of early complications as deep venous thrombosis and pulmonary embolism were compared between 2 groups.RESULTS:Two cases lost in control group and three cases lost in combination group;42 cases were included in each group.Before treatment,there was no statistical significance between these indexes between 2 groups (P＞0.05).After 2 weeks of treatment,Botsford score,FIM score,PT and APTT of 2 groups were enhanced significantly compared to before treatment;high-shear blood viscosity,plasma viscosity,erythrocyte aggregation indexes,D-D,CRP level were decreased significantly compared to before treatment;each index of combination group was significantly better than those of control group,with statistical significance (P＜0.05 or P＜0.01).The incidence of early complications in combination group was 16.7％,which was significantly lower than 35.7％ in control group,with statistical significance (P＜0.05).CONCLUSIONS:The application of Danshen chuanxiongqin injection combined with hyperbaric oxygen in the clinical treatment of ASCI can effectively reduce the risk of deep venous thrombosis,pulmonary embolism and other early complications.It has positive effects on alleviating inflammatory reactions,promoting blood microcirculation and improving prognosis of patients.

Research in length of stay, early complications and treatment cost in radical cystectomy patients with different Charlson Comorbidity Index score / 中国实用护理杂志

Objective To assess the length of stay,early complication and cost of treatment in radical cystectomy (RC) patients with different Charlson Comorbidity Index Score (CCI).Methods A prospective study of a total of 102 patients who underwent RC between March 2012 and August 2014 in Center for Research of Urology in Yunnan Province,China.They were divided into three groups:69 cases in CCI=0 or 1group,19 cases in CCI=2 group,14 cases in CCI≥3 group.Comorbidities were graded according to CCI,and each patient was followed-up for 3 months after RC.Length of stay,early complications and treatment cost were analyzed by statistics.Results A total of 102 patients were analyzed.There were obvious differences with respect to length of stay,early complication and cost of treatment comparing patients in each CCI group,H=20.722,6.025,and 7.047,P＜0.05.The incidence of diversion-related early complications in patients with different CCI showed significant difference,H=7.100,P＜0.05,however,the non diversionrelated early complications did not show significant difference between patients with different CCI,H=2.590,P＞0.05.Conclusions Patients with different CCI showed difference in the length of stay,early complication and cost of treatment in RC patients with different CCI.CCI≥3 might help to identify patients at risk for early complications after RC,especially in the orthotopic urinary diversion operation.Patients' complication should be evaluated standardized before operation and these should be included in patients' consideration.
