    To complement a case series review of button battery impactions managed at our single military tertiary care center with a thorough literature review of laboratory research and clinical cases to develop a protocol to optimize patient care. Specifically, to identify predictive factors of long-term complications which can be used by the pediatric otolaryngologist to guide patient management after button battery impactions. A retrospective review of the Department of Defense's electronic medical record systems was conducted to identify patients with button battery ingestions and then characterize their treatment course. A thorough literature review complemented the lessons learned to identify potentially predictive clinical measures for long-term complications. Eight patients were identified as being treated for button battery impaction in the aerodigestive tract with two sustaining long-term complications. The median age of the patients treated was 33 months old and the median estimated time of impaction in the aerodigestive tract prior to removal was 10.5 h. Time of impaction, anatomic direction of the battery's negative pole, and identifying specific battery parameters were identified as factors that may be employed to predict sequelae. Based on case reviews, advancements in battery manufacturing, and laboratory research, there are distinct clinical factors that should be assessed at the time of initial therapy to guide follow-up management to minimize potential catastrophic sequelae of button battery ingestion.

    BACKGROUND: Amiodarone hydrochloride is an antiarrhythmic agent useful in arrhythmias refractory to standard therapy. Although interstitial pneumonitis is known to be its most serious side effect, several aspects of amiodarone lung toxicity are still controversial. METHODS: Pulmonary side effects were examined in a sample of 61 symptomless patients (mean (SD) age 55 (7) years) who had had long term treatment with amiodarone (daily maintenance dose 400 mg), selected from 482 men attending the University of Barcelona myocardial infarction project. To allow for the confounding effects of coronary artery disease and tobacco history on lung function, 46 patients who had taken amiodarone for more than one year were matched with a control group from the same population. Subjects underwent measurement of lung volumes, arterial blood gas analysis and an incremental bicycle exercise test. RESULTS: Most lung function values were close to predicted values, though there was a small increase in resting alveolar-arterial oxygen tension difference (A-aDO2) at rest (4.8 (1.4) kPa in both groups). There were no differences in the results of forced spirometry or static lung volumes between the two groups, or in the fall in A-aDO2 from rest to exercise. There was a small difference between the amiodarone and the control group in transfer factor for carbon monoxide corrected for lung volume (KCO 1.67 (0.3) and 1.83 (0.3) mmol min-1 kPa-1 l-1 respectively) and in exercise capacity (140 (25) and 120 (30)w). Only three patients showed lung function impairment consistent with pneumonitis. No relation between lung function measures and cumulative doses of amiodarone or desethylamiodarone was found. CONCLUSIONS: The prevalence of clinically evident pulmonary side effects was 4.9%, which is lower than that reported in studies in which higher daily maintenance doses of amiodarone were given. The slightly lower KCO values and lower work load achieved by the patients taking amiodarone suggest a

    Abstract The recent large decrease in splenectomy use for chronic immune thrombocytopenia (ITP) is partly due to still-unsolved questions about long-term safety. We performed the first single-center exposed/unexposed cohort study evaluating the long-term incidence of splenectomy complications in patients with primary ITP. Overall, 83 patients who underwent splenectomy more than 10 years ago (exposed) were matched with 83 nonsplenectomized patients (unexposed) on the date of ITP diagnosis ±5 years, age and gender. After a median follow-up of 192 months (range 0.5–528), 43 patients (52%) achieved overall response after splenectomy. Splenectomized patients experienced more venous thromboembolism (VTE) than controls (n = 13 vs n = 2, P = 0.005). On multivariate analysis, splenectomy was an independent risk factor of VTE (hazard ratio = 4.006, P = 0.032 [95% confidence interval: 1.13–14.21]). Splenectomized patients presented more severe infections on long-term follow-up: all required hospitalization, and 5/26 (19%) infections led to severe sepsis or septic shock and to death for 3 cases (none in controls). However, the incidence of malignancy was similar in both groups, as was cardiovascular risk, which appeared to be related more to ITP than splenectomy. Finally, splenectomy did not significantly decrease overall survival. Despite the risk of thrombosis and severe sepsis, splenectomy remains an effective and curative treatment for ITP. PMID:27902585

    Objectives The aim of this article was to assess the success, safety, complication profile and factors associated with long-term patency of tunnelled peritoneal drains (PleurX) in the treatment of refractory malignant ascites. Methods Over a 4-year period, 28 consecutive patients (32 drain insertions) with refractory malignant ascites were treated with a PleurX drain. The study group comprised 7 males and 21 females (mean age, 61 years). A combination of fluoroscopic and ultrasound guidance was used to insert 4 drains; the remaining 28 drains were inserted under ultrasound guidance alone. Patient history, biochemical profiles, pathological and procedural records and clinical follow-up until death were reviewed. Statistical analysis included multivariate logistic regression analysis and Kaplan–Meier curves (p<0.05 was considered significant). Results There was a 100% technical success rate for the insertion of the drain; there were no procedure-related deaths and no major complications. Only minor complications were reported: three (10%) immediate; three (10%) early; and two (7%) late. Factors significantly associated with these complications included current chemotherapy, low haemoglobin levels, low albumin levels, high white cell count and high c-reactive protein levels. The length of time the drains remained in situ, and therefore patent, ranged from 5 to 365 days (mean, 113 days). Out of the original 28 tunnelled drains, 24 (86%) remained in situ and functioning until the patients’ death. Four (14%) drains dislodged and a subsequent PleurX drain was inserted on the opposite side of the abdominal wall. These new drains remained patent until the patient’s death. The annual event rate was 0.45 events per year. A comorbid diagnosis of renal disease or chemotherapy was significantly related to a decreased length of patency. Conclusion The use of tunnelled peritoneal drains is safe and effective and we would advocate their use as a first-line approach in

    Background Due to the complex therapy and the required high level of immunosuppression, lung recipients are at high risk to develop many different long term complications. Methods From 1993–2000, a total of 54 lung transplantation (LuTx) were performed at our center. Complications, graft and patient survival of this cohort was retrospectively analyzed. Results One/five and ten-year patient survival was 71.4%, 41.2% and 25.4%; at last follow up (4/2010), twelve patients were alive. Of the 39 deceased patients, 26 died from infectious complications. Other causes of death were myocardial infarction (n=1), progressive graft failure (n=1), intracerebral bleeding (n=2), basilary vein thrombosis (n=1), pulmonary emboli (n=1), others (n=7). Surgical complication rate was 27.7% during the first year and 25% for the 12 long term survivors. Perioperative rejection rate was 35%, and 91.6% for the 12 patients currently alive. Infection incidence during first hospitalization was 79.6% (1.3 episodes per transplant) and 100% for long term survivors. Commonly isolated pathogens were cytomegalovirus (56.8%), Aspergillus (29.4%), RSV (13.7%). Other common complications were renal failure (56.8%), osteoporosis (54.9%), hypertension (45%), diabetes mellitus (19.6%). Conclusions Infection and rejection remain the most common complications following LuTx with many other events to be considered. PMID:27293842

    We report a case series of patients with serious long-term complications associated with the injection of permanent dermal fillers. Although such complications are relatively rare, the consequences are potentially life-long, and the psychological and medical effects can often have a profound impact on the patient. The continued routine offering of these treatments will require doctors to communicate effectively with patients about the nature of the complications and the probability of risk compared with alternative treatments.

    One of the common emergencies presenting to the emergency department is a child who has inserted a foreign body into their nose. Of the various things that children insert accidently, the most dangerous are button batteries. We followed up 11 cases of children with history of button battery insertion in the nose for 1 year. We found that all of the patients had developed a septal perforation; other sequelae included nasal adhesions and saddle nose. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Button batteries in the nose are dangerous and can lead to early complications with long-term consequences for the patients. Early diagnosis is required so that they can be removed as soon as possible to prevent the development of complications and long-term sequelae. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to explore the relationships between the short- and long-term results of hypospadias repair and identify the factors that could affect the long-term results of hypospadias repair. Between 1982 and 1988, 142 patients were operated for hypospadias and completed their treatment at Tongji Hospital (Wuhan, China). Their records were analyzed retrospectively, and a detailed questionnaire was mailed to them. One hundred two patients returned the questionnaire. Patients in the proximal hypospadias group, those using Denis-Browne technique, and those with early complications were markedly dissatisfied with the overall results of hypospadias repair and penile appearance. Moreover, their dissatisfaction grew with the number of operations they had. Thirty-nine (95.1%) of 41 patients using the Denis-Browne technique had voiding problems. Forty-nine (48%) of 102 patients felt inhibited in seeking girlfriends or sexual contacts. Moreover, there was a positive correlation between the level of sexual inhibition and operation times. A highly positive correlation was found between the age at the time hypospadias surgery was completed and the extent of being sexually inhibited. The patients in proximal hypospadias group had more erection and ejaculation problems. The short-term results of hypospadias repair could affect the long-term results significantly, and good short-term results also predict long-term ones. The types of hypospadias, procedures, and complications have significant influences on predicting the long-term results of hypospadias repairs.

    AIM To evaluate complications and management outcomes of retained long-term plastic biliary stents. METHODS Endoscopic plastic biliary stent placement was performed in 802 patients at Yeungnam University Hospital between January 2000 and December 2014. Follow-up loss with a subsequently forgotten stent for more than 12 mo occurred in 38 patients. We retrospectively examined the cause of biliary stent insertion, status of stents, complications associated with biliary stents and management outcomes of long-term plastic biliary stents. Continuous variables were analyzed using the t test. Observed frequencies in subsets of the study population were compared using Fisher’s exact test and χ2 tests. Statistical significance was defined as P < 0.05 (two-tailed). RESULTS Mean age of patients was 73.7 ± 12 years and male-to-female ratio was 2.2:1. Indications of plastic biliary stent insertion were bile duct stones (63.2%, 24/38) and benign bile duct stricture (52.6%, 20/38). Mean duration of retained plastic stent was 22.6 ± 12.2 mo, and in 10 cases (26.3%), stents were retained for more than 24 mo. Common bile duct (CBD) stones or sludge were found in most cases (92.1%, 35/38). The most common complication was acute cholangitis (94.7%, 36/38). Stent removal by endoscopic approach was successfully performed in 92.1% (35/38) of the cases. In 3 cases, an additional plastic stent was inserted alongside the previous stent due to failure of the stent removal. Endoscopic removal of bile duct stones was successful in 73.7% (28/38) of the cases. When patients were divided into two groups by duration of stent placement (12 to 24 mo vs over 24 mo), there were no differences in the development of cholangitis, presence of biliary stones, and success rate of endoscopic removal of stones and biliary stents. CONCLUSION The most common complication of retained long-term plastic biliary stents was acute cholangitis associated with CBD stones. Endoscopic management was successfully

    AIM—To evaluate the long term outcome after paediatric inferior vena cava (IVC) thrombosis.
METHODS—A combined retrospective and prospective study on infants and children with IVC thrombosis treated at Aachen and Maastricht University Hospitals between 1980 and 1999.
RESULTS—Forty patients were enrolled, including four with preceding cardiac catheterisation, 18 with central venous saphenous lines, and an additional eight with umbilical venous catheters. Six patients died within three months of diagnosis; one patient was lost to follow up. Twelve of the remaining 33 patients had suffered from limited IVC thrombosis; during follow up (for up to nine years) none showed persisting caval obstruction (successful thrombolysis, n = 2; spontaneous recanalisation, n = 10). The remaining 21 patients presented with extensive IVC thrombosis. During follow up (for up to 18 years) complete restitution was found in only four cases (one thrombolysis, two surgery, one spontaneous recanalisation). Persisting iliac and/or caval venous obstruction occurred in 17patients, including six with thrombolysis. Varicose veins were found in 12, and post-thrombotic syndrome in seven of these cases. According to Kaplan-Meier analysis, 30% of patients with persisting venous disease will develop post-thrombotic syndrome within 10years of the thrombotic event.
CONCLUSIONS—Infants and children with extensive IVC thrombosis are at high risk for persisting venous disease and serious long term complications. Prospective trials are urgently needed to establish effective treatment strategies and to improve long term prognosis. Central venous catheters, contributing to IVC thrombosis in the majority of cases reported here, should be inserted only if essential.

    Long-term central vein catheters have found clinical application in different fields of medicine and particularly in oncology. In fact, the continuous infusion of some drugs has become the standard treatment in a wide variety of cancers, but central vein catheters are not without risks. The authors report their experience with central vein catheters. From January 1,1998, to December 31, 1999, 98 central vein catheters were placed in neoplastic patients. Seventy-seven (78.6%) Groshong and 16 (16.3%) Port-a-cath catheters were used. The central vein catheters were placed under local anesthesia. Before placement of the central vein catheters, the patients were checked by chest X-ray and neck ultrasonography. The procedure was performed under fluoroscopic control. The central vein catheters were flushed periodically with normal saline solution and sodium heparin. Sterile transparent adhesive dressings were used to occlude the operative site. The median follow-up of patients was 9 catheter months (range, 1-24 months). There were a few early and late clinically evident complications. The early complications were dislodgement in 5 cases (5.1%). The late complications were: fibrin sleeve in 1 case (1.1%), thrombosis in 2 cases (2.1%) and skin infection in 4 cases (4.1%). The low prevalence of major complications related to implants and management of these supports an increased use in oncology.

    Currently, valve thrombosis, thromboembolic events and bleeding events account for 75% of all complications that occur after mechanical heart valve replacement. The study aim was to determine the main risk factors for valve-related complications in patients undergoing mechanical heart valve replacement. Data were available from the systematic follow up of patients who had received a CarboMedics bileaflet mechanical heart valve replacement at the authors' institution. Follow up examinations were conducted prospectively at two-year intervals, via questionnaires sent to the patients' general practitioners, or by telephone calls. Between January 1988 and December 2005, a total of 505 consecutive patients (300 males, 205 females; mean age 52 years; range: 5 to 77 years) underwent heart valve replacement using a CarboMedics mechanical prosthesis. Aortic valve replacement (AVR) was performed in 308 patients, mitral valve replacement (MVR) in 134 patients, and double-valve replacement (DVR) in 62 patients. The follow up was 95.4% complete; the mean follow up was 7.5 years, and the total follow up 3,718 patient-years. Thromboembolic and bleeding complications represented the leading cause of valve-related events (104/195), of valve-related mortality (15/25), and of the need for repeat surgery (9/16). Valve thrombosis occurred in 12 patients. Implantation in the mitral position was identified as a risk factor (HR = 15.07; CI: 8.41-23.07; p 0.0001). Thromboembolism occurred in 32 patients; the use of antiplatelet agents was found to be a protective factor (HR = 0.23; CI: 0.08-0.70; p = 0.01). Bleeding events occurred in 52 patients; risk factors for bleeding events included a history of thromboembolic or bleeding complications (HR = 2.70; CI: 1.33-5.26; p = 0.006) and an unstable International Normalized Ratio (INR) (HR = 2.86; CI: 1.01-8.08; p = 0.05). After mechanical heart valve replacement, the only risk factors for bleeding complications were an unstable INR and a

    Esophagectomy is one of the most invasive surgical treatments for digestive tract cancer, and the blood levels of inflammatory cytokines such as interleukin-1, interleukin-6, and interleukin-8 are increased for several hours after surgery or in patients experiencing postoperative complications. CXCR2, an interleukin-8 receptor, is reportedly expressed in several carcinomas, and interleukin-8 signaling promotes cancer cell proliferation. The impact of postoperative complications following esophagectomy on long-term survival is controversial. In this study, we demonstrate the significance of CXCR2 expression and validate the effects of CXCR2 expression and postoperative complications on long-term prognosis of esophageal squamous cell carcinoma using resected specimens. Eighty-two specimens were sectioned from archived, paraffin-embedded tumor tissues obtained from patients with esophageal squamous cell carcinoma who underwent esophagectomy and extended lymphadenectomy for complete resection of cancer in our institute between 1997 and 2002. Immunohistochemistry was performed using a polyclonal antibody to CXCR2, and the correlation of stainability with clinicopathological factors and long-term survival was examined. CXCR2 was expressed in 33 of 82 (40.2 %) specimens. In the CXCR2-positive group, the recurrence-free survival and overall survival rates of patients who developed postoperative complications were both significantly lower than those for patients who did not develop any complications. In contrast, in the CXCR2-negative group, there was no significant difference in long-term prognosis between patients with and without complications. CXCR2 positivity combined with postoperative complications was an independent risk factor for subsequent tumor recurrence, showing the highest hazard ratio. Our results suggest that the patients with CXCR2-positive esophageal cancer who develop postoperative complications have a poor prognosis and should be carefully followed

    Fifty patients who underwent open carpal tunnel release (OCTR) surgery at least 12 months earlier for carpal tunnel syndrome were reviewed, focusing on scar tenderness, pillar pain, and symptoms of neuroma. A total of 55 hands were studied. At an average of 20.2 months of follow-up, 5.5% had Tinel's sign, 7.3% had scar tenderness, 12.7% had pillar pain, and 18% had burning discomfort. Pillar pain was elicited in a much higher fraction of patients by using the "table test" (provocation of pillar pain by having the patient lean with his/her weight on the hands placed on the edge of a table), even when traditional tests were negative. Symptoms and signs are present in a substantial number of patients after OCTR, even after almost 2 years of follow-up. Patients should be informed of the incidence of long-term symptoms and signs after OCTR surgery.

    Background The association of postoperative complications with long-term oncologic outcomes remains unclear. We sought to determine the incidence of complications among patients who underwent surgery for adrenocortical carcinoma (ACC) and define the relationship of morbidity with long-term survival. Methods Patients who underwent surgery for ACC between 1993 and 2014 were identified from 13 academic institutions participating in the US ACC group study. The incidence and type of the postoperative complications, the factors associated with them as well their association with long-term survival were analyzed. Results A total of 265 patients with median age of 52 years (IQR 44–63) were identified; at surgery, the majority of patients underwent an open abdominal procedure (n = 169, 66.8 %). A postoperative complication occurred in 99 patients for a morbidity of 37.4 %; five patients (1.9 %) died in hospital. Factors associated with morbidity included a thoraco-abdominal operative approach (reference: open abdominal; OR 2.85, 95 % CI 1.00–8.18), and a hormonally functional tumor (OR 3.56, 95 % CI 1.65–7.69) (all P < 0.05). Presence of any complication was associated with a worse long-term outcome (median survival: no complication, 58.9 months vs. any complication, 25.1 months; P = 0.009). In multivariate analysis, after adjusting for patient- and disease-related factors postoperative infectious complications independently predicted shorter overall survival (hazard ratio (HR) 5.56, 95 % CI 2.24–13.80; P < 0.001). Conclusion Postoperative complications were independently associated with decreased long-term survival after resection for ACC. The prevention of complications may be important from an oncologic perspective. PMID:26546184

    Background Incisional hernia after abdominal surgery is a well-known complication. Controversy still exists with respect to the choice of hernia repair technique. The objective of this study was to evaluate the long-term recurrence rate as well as surgical complications in a consecutive group of patients undergoing open repair using an onlay mesh technique. Methods Consecutive patients undergoing open incisional hernia repair with onlay-technique between 01/05/1995 and 01/09/2007 at a single institution were included in the study. For follow-up patients were contacted by telephone, and answered a questionnaire containing questions related to the primary operation, the hernia and general risk factors. Patients were examined by a consultant surgeon in the outpatient clinic or in the patient's home if there was suspicion of an incisional hernia recurrence. Results The study included 56 patients with 100% follow-up. The median follow-up was 35 months (range 4–151). Recurrent incisional hernia was found in 8 of 56 patients (15%, 95% CI: 6–24). The overall complication rate was 13% (95% CI, 4–22). All complications were minor and needed no hospital admission. Conclusion This study with a long follow-up showed low recurrence and complication rates in patients undergoing incisional hernia repair with the open onlay technique. PMID:19400934

    New direct oral anticoagulants (NOAC), inhibitors of factor IIa or Xa, are expected to be widely used for the treatment of venous thromboembolic disease, or in case of atrial fibrillation. Such anticoagulant treatments are known to be associated with haemorrhagic complications. Moreover, it is likely that such patients on long-term treatment with NOAC will be exposed to emergency surgery or invasive procedures. Due to the present lack of experience in such conditions, we cannot make recommendations, but only propose management for optimal safety as regards the risk of bleeding in such emergency conditions. In this article, only dabigatran and rivaroxaban were discussed. For emergency surgery at risk of bleeding, we propose to dose the plasmatic concentration of drug. Levels inferior or equal to 30ng/mL for both dabigatran and rivaroxaban, should enable the realization of a high bleeding risk surgery. For higher concentration, it was proposed to postpone surgery by monitoring the evolution of the drug concentration. Action is then defined by the kind of NOAC and its concentration. If the dosage of the drug is not immediately available, proposals only based on the usual tests, PT and aPTT, also are presented. However, these tests do not really assess drug concentration or bleeding risk. In case of severe haemorrhage in a critical organ, it is proposed to reduce the effect of anticoagulant therapy using a nonspecific procoagulant drug (activated prothrombin concentrate, FEIBA, 30-50U/kg, or non-activated 4-factors prothrombin concentrates 50U/kg). For any other type of severe haemorrhage, the administration of such a procoagulant drug, potentially thrombogenic in these patients, will be discussed regarding concentration of NACO and possibilities for mechanical haemostasis.

    The aim of this study was to report technical details, procedure-related complications, and results of endovascular treatment in chronic iliac artery occlusion. Between 2001 and 2008, endovascular treatments of 127 chronic iliac artery occlusions in 118 patients (8 women and 110 men; mean age, 59 years) were retrospectively reviewed. The study was based on Ad Hoc Committee on Reporting Standards (Society for Vascular Surgery/International Society for Cardiovascular Surgery Standards). All occlusions were treated with stent placement with or without preliminary balloon angioplasty. Kaplan-Meier estimators were used to determine patency rates. Univariate and multivariate analyses were performed to determine variables affecting successful recanalization, major complications, early stent thrombosis ({<=}30 days), and primary and secondary patency rates. Initial technical success was achieved in 117 (92%) procedures. Successful recanalization was obtained by antegrade approach in 69 of 77 (90%) procedures and by retrograde approach in 52 of 105 (50%) procedures (p < 0.001). Complications were encountered in 28 (24%) patients [minor in 7 patients (6%) and major in 22 patients (19%)]. One death occurred in the operative period secondary to iliac artery rupture. Early stent thrombosis was seen in eight (7%) patients. Presence of critical limb ischemia (p = 0.03), subintimal recanalization (p = 0.03), and major complication (p = 0.02) were the independent predictors of early stent thrombosis on multivariate analysis. Primary and secondary patency rates at 5 years were 63 and 93%, respectively. Presence of critical limb ischemia, TASC type C iliac lesions, combined occlusions of both common and external iliac arteries, and major complications were associated with decreased patency rates on univariate analysis, whereas these factors were not independent predictors of stent patency on multivariate analysis. In conclusion, endovascular treatment of iliac artery occlusion has a

    Abstract Ophthalmic complications associated with endoscopic sinus surgery (ESS) are quite rare. There is a paucity of reliable data and limited experience on the clinical findings and treatments of these injuries. Our study here is to characterize the types of orbital injury following ESS, in particular extraocular muscle injury, and to evaluate the long-term therapeutic outcomes as compiled from a relatively large sample of Chinese patients. A series of 27 patients (21 males and 6 females; mean age = 42.6 years, ranges: 10–60 years) were retrospectively reviewed. The mean duration of orbital complication was 6.6 months (ranges: 1 day to 24 months). The right eye was affected in 19 patients and the left in 8 patients. All patients had various extraocular muscle dysfunction, including contusion, oculomotor nerve damage, muscle entrapment, muscle transection, and muscle destruction. All patients subjected to strabismus surgery showed an obvious reduction in deviation. Three patients achieved orthophoria without any surgery during the period of observation. All patients displayed mild to complicated orbital hemorrhage that often disappeared within 2 weeks. Optic nerve injury occurred in 29.6% of patients and vision damage in these patients was often irreversible. All patients with ophthalmic complications after ESS had strabismus and extraocular muscle dysfunction. Timing and type of strabismus surgery performed depended on the severity and number of muscles involved as well as the type of injury. This surgery is less effective in cases of restriction factor adhesion and/or entrapment as compared to that of patients with other types of strabismus. Orbital hemorrhages were usually resolved spontaneously, but optic nerve injury was mostly irreversible. PMID:27661034

    Little is known about long-term care workers' cardiovascular disease (CVD) risk. Thus, the authors used baseline objective and subjective data from 98 long-term care staff participating in a worksite health promotion study to provide a comprehensive CVD assessment. The median age of the sample was 32 years ( SD = 13.38). Nine (12.2%) participants smoked and 27 (37.0%) participants reported exposure to secondhand smoke. The average nightly hours of sleep was 6.5 ( SD = 1.18), with 24 (32%) participants reporting sleeping at least fairly bad. Sixty-eight participants (73.1%) were overweight or obese. The median aerobic activity was 0 ( SD = 18.56). Participants ate on average 27 ( SD = 17.34) servings of high fatty and/or salty foods per week. Although blood pressure and cholesterol levels were within normal limits, this population demonstrated poor behavioral CVD risk factors. Given this finding and the young age of the sample, these workers may be ideal candidates for health promotion efforts before health risk factors are present.

    To report the long-term outcome and complication profile of South African patients with proliferative lupus nephritis (PLN). A retrospective review of 66 patients with biopsy-proven PLN [58 diffuse proliferative LN (Class IV) and 8 focal proliferative LN (Class III)] under our care from January 1995 to December 2009 was done. Thirty-three (50 %) patients reached the composite end point of doubling of serum creatinine, end-stage renal disease (ESRD) or death. The 5-, 10- and 15-year cumulative event-free survival rates were 54, 34 and 27 %, respectively. Variables associated with the composite end point were simultaneous diagnosis of SLE and LN (p = 0.048); elevated serum creatinine at onset (p = 0.009); elevated systolic blood pressure (SBP) (p < 0.001) and elevated diastolic blood pressure (DBP) (p < 0.001) on follow-up; and non-remission following induction therapy (p < 0.001). The 5-, 10- and 15-year renal survival rates in our patients were 63, 52 and 52 %, respectively. Hypertension at onset of LN (p = 0.037), nephrotic-range proteinuria (p = 0.033), eGFR < 60 ml/min/1.73 m(2) (p = 0.013) and lack of remission following induction therapy (p < 0.001) were all associated with development of end-stage renal disease (ESRD). Elevated SBP on follow-up (95 % CI 1.03-1.34, p = 0.017) was the only factor associated with composite end point while failure to achieve remission following induction therapy was the only factor associated with ESRD on multivariate analysis. Thirty-five (53 %) patients developed complications with persistent leukopenia, gastritis, sepsis, tuberculosis (TB) and herpes zoster being the leading complications. Ovarian failure occurred in 4 (11 %) patients. The 5-, 10 and 15-year event-free survival rates were 54, 34 and 27 % and failure to achieve remission following induction therapy predicted poor renal survival on multivariate analysis.

    Bronchial stenosis is still a significant source of morbidity and mortality following lung transplantation (LTX) and often mandating placement of a bronchial stent. It has been suggested that although self-expanding metal stents offer excellent early palliation, their long-term complication rates are unacceptably high, and hence, their usage in many transplantation centres has been nearly abandoned. The aim of the study was to assess short- and long-term complication rates and survival in LTX patients with bronchial stenosis treated with insertion of self-expanding metal stents. From January 1997 to March 2013, 435 patients underwent LTX (325 single-LTX and 110 bilateral LTX). Of 503 actual anastomoses at risk (derived by subtracting the number of anastomoses in 30 patients who died within 30 days of LTX), 60 airway complications (11.9%) in 47 patients required self-expanding metal stent insertion. We assessed the early results and long-term outcomes and survival compared with LTX patients in whom stents were not required. The median follow-up period ranged from 1 to 132 (median 54) months. Immediate relief of symptoms was achieved in the vast majority of patients (95%). One-, three- and five-year survival in patients who required self-expanding metal stent placement were 77.7, 66.6 and 55.5%, respectively. The corresponding survival rates in LTX patients without stents were 69, 64.9 and 61.1% (P > 0.05). Self-expanding metal stents are safe and effective tools in the management of airway complications post-LTX and provide immediate improvement in symptoms and pulmonary function tests in the vast majority of cases. The long-term complication rate is low, and mortality is similar to that in LTX patients who did not require stent insertion.

    To analyze indications, surgical technique, complications and long-term outcomes of kidney autotransplantation (KAT) after 26-year experience at a single institution. A retrospective observational study of patients who underwent KAT at our institution (January 1990-December 2016) was carried out. Data collected included indications, surgical technique, complications (Clavien-Dindo), hospital stay and long-term outcomes. Literature review was performed through MEDLINE and ClinicalKey databases including "kidney," "renal," "autotransplantation" and "autograft." Fifteen patients underwent a KAT, with a mean age of 41 years (range 34-59). Indications were vascular abnormalities in 8 cases and ureteral injury in 7. Nephrectomy was performed through laparoscopy in 2 cases (13.3%) and open in 13 (86.7%). Vascular grafts to reperfuse the kidney were used in 8 patients, and ureteral reimplantation was performed in 11 cases. Mean hospital stay was 9.1 days (range 3-20). Seven patients (46.7%) developed postoperative complications: 6 minor (Clavien I-II) and 1 major (Clavien III). After a mean follow-up of 73.1 months (range 7-312), 80% of the patients have a functioning graft. Most common indication reported in the literature is ureteral stricture, especially in the most recent years. Graft survival is variable, and complications are frequent, but usually minor. KAT is an effective treatment for complex ureteral lesions and kidney vascular abnormalities, with good results in the long term. Surgical complications are frequent, but usually minor. As a challenging surgery, it should be performed by experienced kidney transplant surgeons. Complex and proximal ureteral injuries are nowadays the main indication of this procedure.

    2013-01-01

    Despite early surgical repair, congenital esophageal atresia with or without tracheoesophageal fistula (EA ± TEF) has long-term effects on respiratory and gastrointestinal function. This review updates summarizes research published since 2003 on long-term respiratory complications in patients with a history of EA ± TEF. Pulmonary hypoplasia appears to not be rare in patients with EA ± TEF. Tracheomalacia is common and is associated with respiratory symptoms in childhood. Aspiration, associated with esophageal dysmotility and/or gastroesophageal reflux, may lead to reduced pulmonary function and bronchiectasis. Pulmonary function is generally normal, although lower than in control patients, and restrictive defects tend to be commoner than obstructive defects. Abnormal airway reactivity is common and, along with respiratory symptoms, is associated with atopy. However, the inflammatory profile in EA ± TEF patients based on bronchial biopsies and exhaled nitric oxide differs from typical allergic asthma. Recent studies suggest that in older patients, respiratory symptoms tend to be associated with atopy, but abnormal lung function tends to be associated with gastroesophageal reflux and with chest wall abnormalities. Early detection and management of aspiration may be important to help prevent decrements in pulmonary function and serious long-term complications in EA ± TEF patients.

    The purpose of this study was to determine long-term complications of upper-extremity snake envenomations. The records of 73 patients, who were seen for snake bites were obtained; 46 of these patients had bites to the upper extremity, and 27 had bites to the lower extremity. These patients were graded according to the severity of the bite. The snakes involved were eastern diamondback rattlesnake, coral snake, pigmy rattlesnake, water moccasin, and unknown. Fourteen of the 46 patients receiving upper extremity bites were examined by a hand surgeon and an occupational hand therapist 1 to 3.2 years after their bite. Subjective pain data, range-of-motion, intrinsic, extrinsic, finger-flexion tightness, grip strength, pinch strength and objective sensory data were collected. Four patients had continued pain and tissue atrophy at the bite site. There were no long-term sequelae from a missed compartment syndrome.

    Sulfur mustard (SM) and lewisite are vesicant chemical warfare agents that can cause skin blistering and chronic lung complications. During 1929-1945, a Japanese factory produced poisonous gases, which included SM, lewisite and other chemical weapons. The aim of this study was to investigate the chest computed tomography (CT) findings among long-term survivors who worked at this factory. During 2009-2012, we evaluated chest CT findings from 346 long-term survivors who worked at the poison gas factory. Skin lesions were used as an indicator of significant exposure to vesicant agents. Among the 346 individuals, 53 (15%) individuals experienced skin lesions while working at the factory, and chest CT revealed abnormal findings in 179 individuals (52%). Emphysema was the most common CT finding and was observed in 75 individuals (22%), while honeycombing was observed in 8 individuals (2%). Emphysema and honeycombing were more prevalent among individuals with skin lesions, compared to individuals without skin lesions. Multivariate analyses revealed significant associations between the presence of emphysema and skin lesions (p = 0.008). Among individuals who never smoked, individuals with skin lesions (n = 26) exhibited a significantly higher rate of emphysema, compared to individuals without skin lesions (n = 200) (35% versus 7%, respectively; p < 0.001). Among the long-term survivors who worked at the poison gas factory, a history of skin lesions was associated with the presence of emphysema, even among never smokers, which suggests that emphysema might be a long-term complication of exposure to chemical warfare agents.

    More than 50 percent of women will enter a nursing home at some point in their lives. About one-third of men living to age 65 will also need nursing home care. Planning for long-term care is even more important since Medicare covers very little of the cost of such care. The Indiana Partnership Plan is one program designed to help fund the long-term care costs while allowing individuals protect other financial assets.

    The aim of the study was to analyze the long-term survival and the various prognostic factors that influence overall survival in patients undergoing pancreaticoduodenectomy (PD) with non-pancreatic periampullary carcinomas. A retrospective analysis of consecutive patients diagnosed with non-pancreatic periampullary carcinomas who underwent PD at a tertiary cancer center was performed. Univariate analysis of various prognostic factors influencing the disease-free survival (DFS) was performed using log-rank test. Factors identified to be significant in univariate analysis were included in the multivariate analysis, which was performed using the Cox proportional hazard model. The survival estimates were calculated by life-table method. Statistical significance was considered when p value was <0.05. The SPSS v16.0.1 software was used for statistical analysis. Between 1995 and 2010, 78 patients underwent PD with or without (Whipple's operation) pylorus preservation for non-pancreatic periampullary adenocarcinomas. Of these, eight patients received adjuvant chemotherapy. The most common subsite was ampulla (60 patients), followed by the second part duodenum (11 patients), and distal common bile duct (7 patients). The median duration of follow-up of all patients in this study was 50 months. The recurrence rate was 39.7 %. The 5-year disease-free survival and overall survival was 57 %. Patients without nodal metastasis had a non-significant trend towards better 5-year disease-free survival when compared to those with nodal metastasis (64 vs 45 %, p = 0.11). On multivariate analysis, it was found that male gender (p = 0.05) and presence of lymphovascular invasion (p = 0.04) predicted a significantly poor 5-year disease-free survival. Periampullary carcinomas have a favorable prognosis after surgery. Male gender and presence of lymphovascular invasion are independent prognostic factors in patients diagnosed with non-pancreatic periampullary carcinomas who underwent

    In a stratified random sample of 41 long term care (LTC) facilities in Vancouver, 653 residents were chosen to investigate oral health needs and demands for treatment. All of the 603 dentists in the same area were questioned to assess their interest in attending the residents of the institutions. The information from each source was reviewed to identify factors influencing the oral health services to this predominantly elderly and medically compromised population. The majority (60%) of the residents were edentulous and they made infrequent demands on dentists. Two-thirds of those interviewed said that there was nothing wrong with their mouths, but most of those who were aware of a problem wanted it treated, preferably within the institution. They complained about loose or uncomfortable dentures most frequently, and many were dissatisfied with previous dental treatment. The oral mucosal lesions seen on examination were usually symptomless and associated with poor hygiene, while structurally defective dentures and deep carious lesions were not uncommon. The responding 334 dentists indicated that they enjoyed treating elderly patients, 19% had attended an LTC facility, usually to provide an emergency service, and 37% were willing to provide this service if asked. Interest, however, in the service was curtailed by pressures from private practice, concerns about inadequate training and the small demand and poor conditions in the facilities. Although the demand for treatment was not extensive from the residents, they did have problems that were not receiving care.

    Among patients on long-term anticoagulant therapy who undergo laparoscopic cholecystectomy (LC), bleeding complications have not been extensively investigated. The objective of this study was therefore to investigate postoperative bleeding complications prospectively in patients on chronic oral anticoagulation. In the period of January 2002 to December 2007, 44 patients on long-term anticoagulation with warfarin, an oral anticoagulant (OAC), underwent LC in our center. Oral anticoagulant was discontinued 5 days before the planned date of surgery, and patients were admitted to the hospital 3 days before. Upon admission, bridging anticoagulation with enoxaparin, a low molecular weight heparin (LMWH), was started. When their international normalized ratio (INR) decreased to <1.5, patients underwent LC. In the absence of postoperative bleeding complications, OAC and LMWH were resumed on the evening of the day of surgery, and LMWH was continued until each patient's target INR was reached. A comparison group was comprised by 1,421 consecutively enrolled patients with no comorbid disease who underwent LC during the same period. In the comparison group, postoperative bleeding was encountered in 21 patients (1.5%). In the anticoagulation group, postoperative bleeding was encountered in 11 patients (25%) and ranged from minor oozing from a port incision in one patient to hemorrhage, sepsis, and fatality in one patient. In the anticoagulation group, no significant differences were found between patients with and without postoperative bleeding in terms of age, gender, body mass index, American Society of Anesthesiologists score, INR, or other hemostasis parameters. In patients who underwent LC with bridging anticoagulation, postoperative bleeding was markedly more frequent than expected and was not predicted by the usual coagulation parameters. This suggests a need for methods that can indicate which patients on long-term anticoagulation are at risk for postoperative bleeding.

    Argininosuccinate lyase (ASL) is required for the synthesis and channeling of L-arginine to nitric oxide synthase (NOS) for nitric oxide (NO) production. Congenital ASL deficiency causes argininosuccinic aciduria (ASA), the second most common urea-cycle disorder, and leads to deficiency of both ureagenesis and NO production. Subjects with ASA have been reported to develop long-term complications such as hypertension and neurocognitive deficits despite early initiation of therapy and the absence of documented hyperammonemia. In order to distinguish the relative contributions of the hepatic urea-cycle defect from those of the NO deficiency to the phenotype, we performed liver-directed gene therapy in a mouse model of ASA. Whereas the gene therapy corrected the ureagenesis defect, the systemic hypertension in mice could be corrected by treatment with an exogenous NO source. In an ASA subject with severe hypertension refractory to antihypertensive medications, monotherapy with NO supplements resulted in the long-term control of hypertension and a decrease in cardiac hypertrophy. In addition, the NO therapy was associated with an improvement in some neuropsychological parameters pertaining to verbal memory and nonverbal problem solving. Our data show that ASA, in addition to being a classical urea-cycle disorder, is also a model of congenital human NO deficiency and that ASA subjects could potentially benefit from NO supplementation. Hence, NO supplementation should be investigated for the long-term treatment of this condition. PMID:22541557

    Purpose: We report long-term outcomes and complications of craniopharyngioma patients referred to our institution. Methods and Materials: Between 1971 and 2010, 123 consecutive patients received primary treatment for craniopharyngioma in British Columbia and were referred to our institution. The median age was 30 years (range, 2-80 years). Thirty-nine percent of patients were treated primarily with subtotal resection (STR) and radiation therapy (RT), 28% with STR alone, 15% with gross total resection, 11% with cyst drainage (CD) alone, 5% with CD+RT, and 2% with RT alone. Eight percent of patients received intracystic bleomycin (ICB) therapy. Results: Median follow-up was 8.9 years, and study endpoints were reported at 10 years. Ten-year Kaplan-Meier progression-free survival (PFS) was 46%. Patients treated with STR+RT or CD+RT had the highest PFS (82% and 83%, respectively). There were no significant differences between PFS after adjuvant versus salvage RT (84% vs 74%, respectively; P=.6). Disease-specific survival (DSS) was 88%, and overall survival (OS) was 80%. Primary treatment modality did not affect DSS or OS, while older age was a negative prognostic factor for OS but not DSS. Kaplan-Meier rates for visual deterioration, anterior pituitary hormone deficiency, diabetes insipidus, seizure disorder, and cerebrovascular events (CVE) due to treatment, not tumor progression, were 27%, 76%, 45%, 16%, and 11%, respectively. The CVE rate was 29% in patients who received ICB compared to 10% in those who did not (P=.07). Conclusions: We report favorable PFS in patients with craniopharyngioma, especially in those who received RT after surgery. DSS and OS rates were excellent regardless of primary treatment modality. We observed a high incidence of hypopituitarism, visual deterioration, and seizure disorder. Eleven percent of patients experienced CVEs after treatment. There was a suggestion of increased CVE risk in patients treated with ICB.

    The acute replacement of full-thickness abdominal wall has been facilitated by polypropylene mesh (Marlex) (PPM), allowing debridement of nonviable tissue and restoration of abdominal wall integrity without tension. However, no substantial long-term follow-up has been reported on the definitive wound coverage after the use of PPM in open wounds. Since 1976, we have placed PPM in 31 patients; 25 for infectious complication, three for massive bowel distension preventing abdominal closure, and three for shotgun wounds with extensive tissue loss. In 29 of 31 patients, the mesh was placed in heavily contaminated wounds; extensive fasciitis was present in 23 patients and 21 had intra-abdominal abscesses. Following mesh placement, 23 reoperations were required for continuing complications. No patients eviscerated, despite these multiple procedures. Polypropylene mesh was highly effective in restoring abdominal wall continuity. Despite advantages when PPM was used, significant long-term problems developed. Seven patients died from their primary illness in the postoperative period. Nine wounds were closed by granulation and subsequent split-thickness skin grafts. All nine developed mesh extrusion and/or enteric fistulae. Nine wounds healed by secondary intention, six developed enteric fistulae or continuing mesh extrusion. Full-thickness flap coverage after granulation provided the best means of wound closure. Polypropylene mesh had significant early advantages for providing abdominal wall integrity even in the presence of severe infection. However, long-term problems were common when wounds were closed to skin grafts or secondary intention. If the mesh cannot be completely removed, strong consideration should be given to myocutaneous flaps for coverage after the primary illness has resolved. Images Fig. 1. Fig. 2. Fig. 3. PMID:6455099

    Abstract Porous polyethylene is a widely used implants in orbital reconstruction, on which comprehensive clinical analysis, various treatments, and different prognosis according to specific classification principles on long-term complications have not been reported. To investigate the new clinical symptoms, intraoperative findings, treatments, and outcomes of complications long period after previous surgery, resulting from the use of porous polyethylene mesh for orbital fracture reconstruction. A retrospective study was conducted on 21 patients at the Department of Ophthalmology, Shanghai Ninth People's Hospital with orbital complications after orbital fracture reconstruction with porous polyethylene mesh for 4 ± 2.2 years from 2011 to 2013. These data included new clinical symptoms after previous surgery, computerized tomography data, intraoperative findings, treatments, and outcomes. Data from 21 patients were analyzed in this study. Two patients received conservative treatment, while the other 19 patients underwent surgical approaches. Classification principles for orbital complications after orbital wall defect reconstruction with porous polyethylene mesh were formulated according to patients’ new clinical symptoms, computed tomography (CT), and intraoperative findings after previous surgery. In the last follow-up, 19 patients (90.5%) were cured or improved according to our assessment principle. The follow-up ranged from 3 to 45 months (35 months in average). According to specific classification for orbital complications resulting from the use of porous polyethylene mesh for orbital fracture reconstruction, various medical treatments should be carried out, and the prognosis may be different.

    The main objective of this retrospective study was to describe clinical findings, management, and short- and long-term outcome in 27 horses that underwent various surgical techniques for esophageal disease. Surgical techniques (sometimes concurrently) performed were: esophagostomy (n = 14), esophagotomy with primary closure (n = 6), esophagomyotomy (n = 3), and esophagoplasty (n = 2). Esophageal perforation in 5 horses was treated by ventral drainage; 3 horses had the esophageal defect sutured (n = 3). Feeding tubes were placed in 15 horses. Postoperative complications occurred in 52% (14/27) with a median of 3 complications/horse (range: 1 to 7). Significantly more complications occurred in horses with a perforated esophagus. Eighteen horses (18/27; 67%) were discharged. Most horses (8/9; 89%) with a lesion located in the proximal esophagus were discharged. Horses with a higher number of postoperative complications, particularly postoperative infection, were more likely to be euthanized. One year after surgery, 41% of the horses were alive and free of complications.

    The prevalence of obesity is increasing in the United States. Obesity has been associated with worse surgical outcomes, but its impact on long-term outcomes in gastric cancer is unclear. The aim of this study was to evaluate the effects of being overweight on surgical and long-term outcomes for patients with gastric cancer. Patients who underwent curative intent resection for gastric carcinoma from 1985 to 2007 were identified from a prospectively collected gastric cancer database. Overweight was defined as a body mass index (BMI) of 25 kg/m(2) or higher. Clinical outcomes of overweight and nonoverweight patients were compared. From the total population of 1,853 patients, 1,125 (60.7%) were overweight. Overweight patients tended to have more proximal tumors and a lower T stage. Accurate complication data were available on a subset of patients from 2000 to 2007. A BMI of ≥25 was associated with increased postoperative complications (47.9 vs. 35.8%, p < 0.001). This was mainly due to an increase in the rate of wound infections (8.9 vs. 4.7%, p = 0.02) and anastomotic leaks (11.8 vs. 5.4%, p = 0.002). Multivariate logistic regression analysis showed that higher BMI, total gastrectomy, and use of neoadjuvant chemotherapy were associated with increased wound infection and anastomotic leak. Overweight patients were less likely to have adequate lymph node staging (73.3 vs. 79.2%, p = 0.047). There was no difference in overall survival or disease-specific survival between the two groups. Increased BMI is a predictor of increased postoperative complications, including anastomotic leak, but it is not a predictor of survival in gastric cancer.

    Cardiac tamponade constitutes the most severe clinical consequence of a coronary perforation (CP) during percutaneous coronary intervention (PCI). We analyzed 23,399 PCIs and identified 73 patients complicated by CP (0.31%), of which 26 developed tamponade (0.11%). Patients were divided into two groups: CP with tamponade (group A) and CP without tamponade (group B). Characteristics and outcomes were compared and a multivariate model was developed to evaluate the independent contribution of tamponade on mortality. All patients with tamponade were treated with pericardiocentesis. Tamponade increased the risk of death by more than 3-fold (odds ratio [OR] = 3.3; 95% confidence interval [CI],1.01-10.6; P=.047) relative to patients with CP but no tamponade. CP with tamponade during non-elective PCI carried a significantly worse long-term prognosis (P=.001) than the same complications during elective PCI. The use of glycoprotein IIb/IIIa inhibitors and bivalirudin did not differ between groups. Polytetrafluoroethylene-covered stents were used similarly between the two groups, while coil embolization was used more often in group A (P=.003). Emergent cardiac surgery was needed in 3 patients (11.5%) in group A versus 1 patient (2.1%) in group B. Tamponade complicating CP during PCI has short- and long-term major adverse effects. In-hospital mortality after tamponade and referral for emergent surgical treatment have decreased. Nonetheless, tamponade in this setting increases risk of death by >3-fold. PCI of complex lesions with an expected increased risk of perforation should be undertaken cautiously among patients with non-elective PCI because of increased early and late risk of death.

    Abstract Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm2/m2 for women and 40.8 cm2/m2 for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P < 0.001), but not for total complications. However, sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P < 0.001) and disease-free survival (HR = 1.620, P < 0.001). Under the adjusted tumor-node-metastasis (TNM) stage, sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover

    Abstract Laparoscopic rectal cancer surgery has technical difficulties with a higher complication rate than colon cancer. However, few studies have examined whether postoperative complications are associated with oncologic outcomes. The aim of this study is to evaluate the impact of postoperative complications on long-term oncologic outcomes after laparoscopic low anterior resection for rectal cancer. Between January 2005 and December 2012, we evaluated 686 consecutive patients who underwent laparoscopic low anterior resection for stage I-III rectal cancer. Patients were divided into complication (n = 175) and noncomplication (n = 511) groups. The median follow-up period was 38 months (range, 2–118). We compared perioperative clinicopathologic outcomes, 5-year survival, and local recurrence between groups and evaluated prognostic factors. Five-year overall survival rates were 91.4% and 89.2% (P = 0.234) and 5-year disease-free survival rates were 83.2% and 77.7% (P = 0.002) in the noncomplication and complication groups for all stages, respectively. For stage I cancer, both the 5-year overall survival and the 5-year disease-free survival rate of the complication group were lower than the noncomplication group. Local recurrence rates were 3.1% and 7.8% in the noncomplication and complication groups, respectively (P = 0.002). In multivariate analysis, the presence of postoperative complications was a significant predictor of 5-year disease-free survival (hazard ratio, 1.65; P = 0.012). Postoperative complications had a negative impact on 5-year disease-free survival after laparoscopic low anterior resection for rectal cancer. The rate of local recurrence in the complication group increased more than the noncomplication group. In particular, postoperative complications were associated with poorer oncologic outcomes for stage I cancer. Laparoscopic surgery is preferred for early-stage rectal cancer so careful attention should be paid to avoid

    AIM: To determine the long-term hepatobiliary complications of alveolar echinococcosis (AE) and treatment options using interventional methods. METHODS: Included in the study were 35 patients with AE enrolled in the Echinococcus Multilocularis Data Bank of the University Hospital of Ulm. Patients underwent endoscopic intervention for treatment of hepatobiliary complications between 1979 and 2012. Patients’ epidemiologic data, clinical symptoms, and indications for the intervention, the type of intervention and any additional procedures, hepatic laboratory parameters (pre- and post-intervention), medication and surgical treatment (pre- and post-intervention), as well as complications associated with the intervention and patients‘ subsequent clinical courses were analyzed. In order to compare patients with AE with and without history of intervention, data from an additional 322 patients with AE who had not experienced hepatobiliary complications and had not undergone endoscopic intervention were retrieved and analyzed. RESULTS: Included in the study were 22 male and 13 female patients whose average age at first diagnosis was 48.1 years and 52.7 years at the time of intervention. The average time elapsed between first diagnosis and onset of hepatobiliary complications was 3.7 years. The most common symptoms were jaundice, abdominal pains, and weight loss. The number of interventions per patient ranged from one to ten. Endoscopic retrograde cholangiopancreatography (ERCP) was most frequently performed in combination with stent placement (82.9%), followed by percutaneous transhepatic cholangiodrainage (31.4%) and ERCP without stent placement (22.9%). In 14.3% of cases, magnetic resonance cholangiopancreatography was performed. A total of eight patients received a biliary stent. A comparison of biochemical hepatic function parameters at first diagnosis between patients who had or had not undergone intervention revealed that these were significantly elevated in six

    The purpose of this study is to evaluate the complications of peripherally inserted central catheters (PICCs) in orthopedic patients with chronic bone orthopedic infection. The institutional review board approved this retrospective study and informed consent was waived. Records of 180 consecutives PICCs placed in patients hospitalized in the orthopedic surgery department were reviewed. All patients had bones infections necessitating a long-term intravenous antibiotics therapy. All PICC complications were recorded during the patient hospitalization: infection [catheter-related bloodstream infection (CRBSI), central line associated bloodstream infection (CLABSI), exit-site infection, septic phlebitis], thrombosis, occlusion, mechanical complication (accidental withdrawal, malposition, median nerve irritation). One hundred and eighty PICCs were placed in 136 patients. Mean duration of catheterization was 21 days (total 3911 PICC-days). Thirty-six PICCs (20%) were removed due to complications (9.2 complications per 1000 PICC-days): 14 (8%) infections (one CRBSI (Pseudomonas aeruginosa), one septic phlebitis (P. aeruginosa), two exit-site infections and 10 CLABSIs), 11 (6%) occlusions, and 12 (7%) mechanical complications (10 accidental withdrawals, one malposition, one median nerve irritation). One patient had two complications simultaneously. After multivariate analysis, two risk factors were significantly associated with the overall occurrence of complications: age more than 70 years [OR = 2.89 (1.06-7.89], p = 0.04] and number of lumen at least two [OR = 2.64 (1.03-6.75), p = 0.04]. Even in orthopedic patients with chronic orthopedic bone infection, PICCs have a low rate of complication. The increasing lumen number of the PICC is a potential risk factor in our series.

    Background Maquet III procedure, unloved due to its complications (2% to 59%), has been progressively abandoned. At long-term follow-up, what happens to patients with complications that exceeded the initial ones (Acta Orthop Scand 60:20, 1989)? We retrospectively studied patients who were submitted to Maquet III procedure, by functional and radiologic long-term outcomes, in order to determine if this surgery has or has not fulfilled its initially proposed objectives. From 1970 to 1991, 116 patients benefit from the Maquet III procedure. From this, we were able to review in 2011, 23 patients (25 knees) who went through a single Maquet III procedure. Of these patients, 52% were males. Age at surgery was 39.7 ± 11.4, with a postoperative follow-up of 27.2 ± 3.1 years. Methods A questionnaire has been prepared for collecting data, and it has been supplemented by clinical records. We evaluated the preoperative complaints, postoperative complications, and range of motion during the recovery time, as well as the postoperative pain-absence period. All patients underwent an objective assessment using the visual analog scale (VAS) at rest and activity, and the Kujala patellofemoral scoring system. A radiological assessment was also made in order to evaluate the arthrosis degree. The bicondylo-patellar angle described by Delgado-Martins (Arch Orthop Traumat Surg 96:303–304, 1980) was used to measure patellar tilt, and the Caton-Deschamps index to calculate the patellar height. Results Only one knee had benefited from a total knee arthroplasty (20 years after the Maquet III procedure). Preoperative complains were mainly anterior knee pain, crepitus, and patellar instability. Nowadays, 10 patients (40%) still are pain free. Others had an average period without pain of 19.1 ± 6.1 years. VAS at rest was 1.7 ± 0.7 and in activity 4.4 ± 3.0. KPS was 61.9 ± 22.3 points. X-ray shows that 40% had a Kellgren-Lawrence grade of 1 at the patellofemoral joint. Conclusion Maquet

    To understand the risk factors and long-term impact and results of aortic valve surgery in patients over age 80. We consecutively evaluated 255 octogenarians who were operated on between 2000 and 2013 and referred for aortic valve disease (isolated or combined with coronary artery disease), which, even when associated with other diseases, was the primary cause of the patient's functional limitation. The mortality rate decreased from 14.08% (2000-2004) to 7.7% (isolated valve surgery, 4.4%; with coronary bypass, 3.3%) (2010-2013). The independent risk factors associated with mortality were urgent surgery, combined procedures, peripheral vascular disease, a postsurgery hematocrit level <24% and the need for transfusion. More than 50% of the patients experienced a postoperative complication. Blood product transfusions were associated with renal and respiratory failure, and preoperative anemia was associated with an increased rate of myocardial infarction and stroke. Survival at 1, 3, 5 and 10 years was 79.5, 74.3, 63.6 and 30.5%, respectively, with 91.5% of patients in NYHA functional class I-II. Long-term survival was lower for cases of preoperative left ventricular dysfunction. The EuroSCORE I logistics score was not useful for our population as a predictor of mortality or of medium to long-term survival. The morbidity and mortality of aortic valve surgery for patients over age 80 has decreased in recent years, although it remains higher when valve surgery is combined with coronary surgery. The presence of preoperative left ventricular dysfunction decreases long-term survival. Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI). All rights reserved.

  13. Plant community feedbacks and long-term ecosystem responses to multi-factored global change.

    2014-07-14

    While short-term plant responses to global change are driven by physiological mechanisms, which are represented relatively well by models, long-term ecosystem responses to global change may be determined by shifts in plant community structure resulting from other ecological phenomena such as interspecific interactions, which are represented poorly by models. In single-factor scenarios, plant communities often adjust to increase ecosystem response to that factor. For instance, some early global change experiments showed that elevated CO2 favours plants that respond strongly to elevated CO2, generally amplifying the response of ecosystem productivity to elevated CO2, a positive community feedback. However, most ecosystems are subject to multiple drivers of change, which can complicate the community feedback effect in ways that are more difficult to generalize. Recent studies have shown that (i) shifts in plant community structure cannot be reliably predicted from short-term plant physiological response to global change and (ii) that the ecosystem response to multi-factored change is commonly less than the sum of its parts. Here, we survey results from long-term field manipulations to examine the role community shifts may play in explaining these common findings. We use a simple model to examine the potential importance of community shifts in governing ecosystem response. Empirical evidence and the model demonstrate that with multi-factored change, the ecosystem response depends on community feedbacks, and that the magnitude of ecosystem response will depend on the relationship between plant response to one factor and plant response to another factor. Tradeoffs in the ability of plants to respond positively to, or to tolerate, different global change drivers may underlie generalizable patterns of covariance in responses to different drivers of change across plant taxa. Mechanistic understanding of these patterns will help predict the community feedbacks that determine

    Purpose: Despite some advantages to their use, long-term central venous catheters (CVCs) are associated with complications for patients who require chemotherapy. Understanding of these risks in commercially insured populations is limited. This information can inform medical policies that ensure the appropriate use of venous access devices. This study's objectives were to assess the extent of variation in use of long-term CVCs in a cohort of commercially insured women with breast cancer, and to assess risks of associated complications. Methods: Retrospective cohort analysis was conducted using health insurance claims between January 2006 and October 2013. The cohort included commercially insured women age ≥ 18 years diagnosed with breast cancer who received infusion chemotherapy (N = 31,047). We conducted matched and case-mix adjusted Cox proportional hazard modeling to assess differences in bloodstream infections and thrombovascular complications between patients using long-term CVCs and those using temporary intravenous catheters. Results: Approximately two thirds of the cohort had a long-term CVC, although rates varied across regions (57% to 75%), health plans (65% to 70%), and insurance coverage (63% to 68%). After propensity score matching, the adjusted hazard ratio for infection was 2.70 (95% CI, 2.31 to 3.16) and thrombovascular complications, 2.61 (95% CI, 2.33 to 2.93) in patients with long-term CVCs compared with those with temporary intravenous catheters. Conclusion: Although long-term CVCs may have benefits, they are associated with increased morbidity. Regional and health plan variation in long-term CVC insertion suggests that some of their use reflects provider- or institution-driven variation in practice. Evidence-based guidelines and tools may help decrease discretionary use of long-term CVCs. PMID:26265170

    The growing prevalence of severe obesity, combined with the failure of conservative treatments, has led to a significant spread of bariatric surgical procedures. The aim of this study was to emphasize the need of adequate presurgery patient selection and close follow-up after malabsorptive procedures for bariatric surgery. The study retrospectively evaluated 25 (20 F, 5 M; mean age 43 ± 13 y) obese patients (mean weight before intervention 134 ± 30.7 kg, body mass index 50.7 ± 10.1 kg/m(2)) attending our outpatient clinical nutrition unit for severe malabsorption and secondary malnutrition after surgical intervention that had been performed outside the regional area. All patients received personalized dietetic indications; in 12 of 25 (48%) cases integrated by oral protein supplements and in 5 of 25 (20%) by medium chain triglycerides. According to screening exams, patients were prescribed oral/parenteral iron, vitamins A, B group, D, and folate supplementation. In 14 of 25 (56%) patients, parenteral hydration and in 4 of 25 (16%), long-term parenteral nutrition was required. Five patients required hospitalization for severely complicated protein-energy malnutrition. Nutritional deficiencies are common after malabsorptive procedures for bariatric surgery; these can be present or latent before surgery, frequently going unrecognized and/or inadequately treated particularly when patients are not strictly followed up by the operating center. Despite the adequate-even intensive-intervention, clinical nutritional status moderately improved in all patients. Copyright © 2014 Elsevier Inc. All rights reserved.

    In a remarkably short time, Laparoscopic Adjustable Gastric Banding (LAGB) has become a common operation for morbid obesity in Europe and elsewhere. More than 70,000 such procedures have been performed in recent years. We used LAGB as a routine treatment for morbid obesity in 90 patients between 1994 and 1996. We agree with other authors that LAGB is the least invasive of all gastric restrictive procedures, resulting in a low perioperative mortality and morbidity. The weight loss appears to be similar to that obtained by vertical banded gastroplasty (VBG). However, our long-term follow-up studies, including endoscopic examinations, as well as recent data in the literature also indicate a number of significant problems with LAGB. Patient discomfort occurs frequently in the postoperative course. When questioned according to a standardized protocol 2 years after surgery, every other patient in our series admitted heartburn and acid regurgitation. Regular endoscopic surveillance revealed a prevalence of erosive esophagitis of 44%. After a median follow-up of 7 years, 58% of the patients had been reoperated on, almost always with excision of the banding system and conversion to Roux-en-Y gastric bypass (RYGBP). The reasons for reoperation were esophagitis, band erosion, pouch dilatation, leakage from the balloon, and esophageal dilatation, complications that also have been described in several recent papers in the literature. Our prediction is that LAGB will not stand the test of time. Copyright 2002, Elsevier Science (USA). All rights reserved.

  17. Can ART treatment reduce long-term complications by reducing inflammation?

    2014-01-01

    Purpose of review Serious non-AIDS events or non-infectious complications of HIV infection far outnumber AIDS events in the current combination antiretroviral therapy (ART) era and are attributed to chronic inflammation. Thus, a better understanding of why inflammation persists on ART will assist in developing better therapeutic strategies, including optimal timing of ART initiation. Recent findings Markers of inflammation and coagulation, such as D-dimer, IL-6, C-reactive protein, soluble CD14, and soluble CD163, predict end-organ disease and mortality, whereas markers of T cell activation appear more predictive of CD4 T cell decline, AIDS events, or response to therapy. Initiating ART at high CD4 T cell counts can result in less inflammation as supported by studies in acute and early HIV infection, but antiretroviral drugs may differentially affect inflammatory pathways. Decreasing inflammation in HIV-uninfected subjects may decrease morbidity, but long-term outcomes studies in HIV-infected individuals are lacking. Summary Circulating biomarkers of inflammation are among the strongest predictors of non-AIDS outcomes in treated HIV infection. With additional investigation, they may serve in the future as specific end-organ disease surrogate endpoints and may help identify those patients at highest risk of non-AIDS events who may benefit from either early ART and/or potential adjuvant anti-inflammatory therapies.

    Chemoradiation therapy is widely used to treat both inoperable and operable patients, and is less invasive than surgery. Although the number of long-term survivors who have received chemoradiation therapy is increasing, the long-term toxicity pattern and cumulative incidence of toxicity regarding this modality are poorly understood. Classically, chemoradiation therapy for esophageal cancer consists of an anterior–posterior field and a subsequent oblique boost field. We retrospectively analyzed patients who were treated with definitive chemoradiation therapy for esophageal cancer using this classical method from 1999 to 2008. For the assessment of toxicity, the National Cancer Institute Common Toxicity Criteria Version 3.0 was adopted. A total of 101 patients were analyzed. The median follow-up time was 16 months for all patients and 62 months for the surviving patients. Eleven patients experienced late toxicities of ≥Grade 3. Two patients died of late toxicities. The 3- and 5-year cumulative incidences for the first late cardiopulmonary toxicities of ≥Grade 3 were 17.4% and 20.8%, respectively. Cardiopulmonary effusions were observed within the first 3 years of completion of the initial treatment in seven out of eight patients. Sudden death and cardiac ischemia were observed over a 10-year period. Older age was found to be a risk factor for late toxicity after definitive chemoradiation therapy for esophageal cancer. Substantial toxicities were observed in patients who had received chemoradiation therapy for esophageal cancer using the classical method. To minimize the incidence of late toxicity, more sophisticated radiation techniques may be useful. PMID:27475126

    Primary degenerative arthritis of the elbow is an uncommon disorder that recently has been more clearly recognized. The purpose of this study was to analyze the long-term results and complications of ulnohumeral arthroplasty as treatment of primary osteoarthritis of the elbow and to document any tendency for recurrence of the arthritis after the procedure. The results of ulnohumeral arthroplasties performed at our institution, between 1986 and 1996, in forty-six elbows (forty-five patients) with primary osteoarthritis were reviewed at an average of eighty months (range, twenty-four to 164 months) after the operation. There were forty-four men and one woman with a mean age of forty-eight years. All patients complained of pain with terminal elbow extension. The pain was associated with locking in fourteen elbows and with ulnar nerve symptoms in twelve. The surgical procedure involved fenestration of the olecranon fossa and excision of olecranon and coronoid osteophytes in all patients, with removal of loose bodies in thirty-six elbows. A capsular release was performed in nineteen elbows, and an ulnar nerve transposition or neurolysis was done in eight. Preoperative and follow-up assessment included evaluation of elbow pain and range of motion with the Mayo Elbow Performance Score. The mean arc of flexion-extension improved from 79 degrees (range, 10 degrees to 135 degrees) preoperatively to 101 degrees (range, 45 degrees to 135 degrees) at the time of follow-up (p < 0.05). At the last follow-up examination, thirty-five elbows (76%) were not painful or were only mildly painful and eleven were moderately or severely painful. According to the Mayo Elbow Performance Score, the result was excellent for twenty-six elbows, good for eight, fair for four, and poor for eight. Thirteen of the forty-five patients reported some degree of ulnar nerve symptoms postoperatively, and six of them required another operation to decompress or translocate the nerve. Two other patients

    The Iraqi government used a range of chemical weapons, including blistering and nerve agents, against Iraqi Kurdish civilians in the 1980s. Few data exist about the long-term respiratory consequences of this exposure. In this study, Kurdish subjects with a history of exposure to chemical weapons were invited to attend a clinical assessment, including a review of their history, physical examination, and a high-resolution computed tomography (CT) of the thorax. Blistering at the time of exposure was used to define significant exposure to mustard gas. Results were compared between two groups of blistering and nonblistering. Four hundred seventy-nine subjects were studied; 45.7% male and 54.3% female. The mean age and standard deviation (mean +/- SD) of the cases was 43.1 +/- 13.7. Spirometry was abnormal in 15.2% of subjects and air trapping was present on CT scan in 46.6% and did not differ between patients with (n = 278) or without a history of blistering. Respiratory symptoms, including dyspnea, cough, and sputum production, were more common in subjects with a history of blistering (all p < .005) and blistering was also associated with a lower forced expiratory volume in one second (FEV(1)) (p < .0001). Severe complications were most common in subjects from Halabja who also made up the majority of participants. These results show that objective abnormalities are common in people with symptoms attributed to prior exposure to chemical agent. Blistering at the time of exposure was associated with more respiratory symptoms and worse lung function, but not with CT appearances. The high proportion of severe cases in comparison to reports from Iran may reflect the historical absence of effective early treatment, including strategies to reduce prolonged early exposure in this population.

    Resuspension of contaminated soil into the atmosphere is one of the key processes that must be considered in the estimation of inhalation doses to humans. Data for air and soil contamination collected in Ukraine over several years since the Chernobyl accident have permitted analysis of resuspension in terms of the underlying mechanisms. Various empirical models for the resuspension factor as a function of time (e.g. Linsley, Garland, Anspaugh, etc.) are compared to the observed resuspension factors over time (9 yr) at two sites; in general, these models give overestimates for the resuspension factor as a function of time. The observed values of the resuspension factor range from greater than 10 -5 m -1 at early time points to around 10 -10 m -1 at later points. The uncertainty in the resuspension factor is decreased to within 1 order of magnitude if annual averaging of the experimental data is used and if the resuspension factor is determined as a function of time and of the predominant regional conditions of vegetative cover and climate.

    Lung transplantation is a life-saving procedure for patients who have end-stage lung disease. The frequency and severity of complications have not been fully characterized. We hypothesized that early in-hospital, postoperative complications decrease long-term survival. We retrospectively identified in-hospital complications in lung transplant recipients, from the period January 2007 to October 2013. Complications were graded using the extended Accordion Severity Grading System (ASGS). Complications were categorized by event and organ system. Survival analysis was performed (P < .05) using a time-dependent model. Among 748 eligible patients, 3381 independent in-hospital, postoperative complications occurred in 92.78% of patients. Median follow-up was 5.4 years. Complications associated with significant decrease in 5-year survival were: renal (hazard ratio [HR] 2.58, 95% confidence interval [CI] 1.40-4.48); hepatic (HR 4.08, 95% CI 2.86-5.82); cardiac (HR 1.95, 95% CI 1.56-2.45). The maximum ASGS of ≥5 (18.5% vs 73.8%), and the weighted ASGS sum >10 (2.5% vs 73.8%), were found to be significant predictors of long-term survival. Multivariate analysis identified a weighted ASGS sum of >10, and renal, cardiac, and vascular complications as predictors of decreased long-term survival. Rigorous delineation of complications after lung transplantation showed that grade 5 ASGS in-hospital postoperative complications, and a weighted ASGS sum >10, were independent predictors of decreased long-term survival well beyond the initial perioperative period. These results may identify important targets for best practice guidelines and quality-of-care measures after lung transplantation. Copyright © 2016 The American Association for Thoracic Surgery.

    Long-term culture of canine marrow cells allows in vitro studies of the hematopoietic system of the dog and characterization of early progenitor cells. Colonies of fresh marrow cells grew equally good in both agar or methylcellulose supplemented with fetal calf serum, while colonies of long-term cultures required agar-based medium containing human serum. Optimum colony growth was obtained when stem cell factor (SCF) and granulocyte-macrophage-colony-stimulating factor (GM-CSF) were used as growth stimuli of colony forming units (CFU). Similar results were achieved with several cell culture media. Addition of hydrocortisone to long-term cultures improved clonogenic growth of cultured cells. Addition of 2-mercaptoethanol had no effect. Strong differences were observed in long-term culture with different horse serum lots and the addition of fetal calf serum to long-term culture suppressed CFU growth of cultured cells. Recharging of cultures with fresh marrow cells on day 7 of culture improved CFU growth only in the following week but had little effect on the outcome. Adding SCF to long-term cultures led to differentiation of more primitive cells and destruction of the stromal layer. Investigation of purified and cultured cell populations was possible when preestablished long-term cultures as stromal layers were used. Loss of long-term culture-initiating ability could be demonstrated in this system with lineage negative marrow cells expanded ex vivo with SCF and GM-CSF.

    The replacement of implantable cardioverter-defibrillators (ICDs) may give rise to considerable clinical consequences, the importance of which is underrated by the medical community. Replacement-related adverse events are difficult to identify and require monitoring of both short-term complications and long-term patient outcome. The aim of this study is to perform a structured evaluation of both short- and long-term adverse events and a cost analysis of consecutive ICD replacement procedures. Detect Long-term Complications After ICD Replacement (DECODE) is a prospective, single-arm, multicenter cohort study designed to estimate long-term complication rates (at 12 months and 5 years) in patients undergoing ICD generator replacement. The study will also evaluate predictors of complications, patient management before and during the replacement procedure in clinical practice, and the costs related to use of health care resources. About 800 consecutive patients with standard indications for ICD generator replacement will be enrolled in this study. The decision to undertake generator replacement/upgrade will be made according to the investigators' own judgment (which will be recorded). Patients will be followed for 60 months through periodic in-hospital examinations or remote monitoring. Detailed data on complications related to ICD replacement in current clinical practice are still lacking. The analysis of adverse events will reveal the value of new preventive strategies, thereby yielding both clinical and economic benefits. Moreover, assessment of complication rates after ICD replacement in a real-life setting will help estimate the actual long-term cost of ICD therapy and assess the real impact of increasing ICD longevity on cost-effectiveness. © 2015 Wiley Periodicals, Inc.

    Catheter-related central thrombosis is a rare complication of long-term central line. We describe the case of an asymptomatic boy who was diagnosed a calcified thrombus in right atrium eight years after the removal of a long-term central venous device. Although the most appropriate therapeutic approach for managing floating right heart thrombi remains to be determined, surgical removal is an effective and safe procedure for calcified long-standing thrombus and it is to be preferred in elective conditions especially in young asymptomatic patients without hemodynamic involvement, that are at low risk of surgery-related morbidity and mortality.

    OBJECTIVE: To understand the factors important in the purchase of long-term care insurance through the Robert Wood Johnson Foundation Partnership for Long-Term Care. DATA SOURCES: Information on the Partnership programs, telephone surveys, data on Partnership purchasers, and random sample frames. STUDY DESIGN: Logistic regression analysis is used to examine characteristics associated with the purchase of a Partnership insurance policy. Independent variables are health status, demographic and financial characteristics, knowledge, and attitudes. DATA COLLECTION: A telephone survey of Partnership purchasers and a random sample of the population in each Partnership state were conducted. Survey questions included health status, opinions about long-term care and long-term care insurance, financial planning, demographic characteristics, and income and assets. PRINCIPAL FINDINGS: Important in the purchase of a Partnership policy were variables associated with education and knowledge about long-term care. Other important factors include attitudes and health status. Partnership purchase is associated with higher income and asset levels up to a point, with the effect plateauing and decreasing at the highest income and asset levels. CONCLUSIONS: Improved education and knowledge are important in increasing long-term care insurance purchase. Attitudes about having a caregiver, and about the government's role in paying for long-term care as well as the potential purchaser's willingness to consider nursing home care affect policy purchase. Also associated with Partnership policy purchase are better health and middle income and asset levels. PMID:9618667

    Direct new oral anticoagulants (NOACs) - inhibitors of thrombin or factor Xa - are intended to be used largely in the treatment of venous thromboembolic disease or the prevention of systematic embolism in atrial fibrillation, instead of vitamin K antagonists. Like any anticoagulant treatment, they are associated with spontaneous or provoked haemorrhagic risk. Furthermore, a significant proportion of treated patients are likely to be exposed to emergency surgery or invasive procedures. Given the absence of a specific antidote, the action to be taken in these situations must be defined. The lack of data means that it is only possible to issue proposals rather than recommendations, which will evolve according to accumulated experience. The proposals presented here apply to dabigatran (Pradaxa(®)) and rivaroxaban (Xarelto(®)); data for apixaban and edoxaban are still scarce. For urgent surgery with haemorrhagic risk, the drug plasma concentration should be less or equal to 30ng/mL for dabigatran and rivaroxaban should enable surgery associated with a high bleeding risk. Beyond that, if possible, the intervention should be postponed by monitoring the drug concentration. The course to follow is then defined according to the NOAC and its concentration. If the anticoagulant dosage is not immediately available, worse propositions, based on the usual tests (prothrombin time and activated partial thromboplastin time), are presented. However, these tests do not really assess drug concentration or the risk of bleeding that depends on it. In case of serious bleeding in a critical organ, the effect of anticoagulant therapy should be reduced using a non-specific procoagulant drug as a first-line approach: activated prothrombin complex concentrate (aPCC) (FEIBA(®) 30-50U/kg) or non-activated PCC (50U/kg). In addition, for any other type of severe haemorrhage, the administration of a procoagulant drug, which is potentially thrombogenic in these patients, is discussed according

    The influence of acute graft pyelonephritis (AGPN) on graft outcome in renal transplant recipients still remains controversial. We retrospectively analysed 189 patients (113 males; mean age: 49.7 ± 13.1 years) undergoing renal transplantation at the University Hospital 12 de Octubre (Madrid, Spain) from January 2002 to December 2004, with a minimum follow-up of 36 months. Factors associated with AGPN were assessed by logistic regression analysis. Long-term graft function was compared according to the occurrence of this complication during follow-up. 'Decline in renal graft function' was defined as the increase in serum creatinine (SC) levels > 0.33 mg/dL between Month 3 and Year 1 after transplantation. Nineteen patients (10.0%) were diagnosed with 25 episodes of AGPN (incidence rate: 4.4 episodes per 100 patient-years). The presence of glomerulonephritis as the underlying disease [odds ratio (OR) 4.2; 95% confidence interval (95%CI): 1.3-14.1] and the previous occurrence of two to five (OR 9.4; 95%CI: 1.5-56.8) or more than five episodes of asymptomatic bacteriuria after transplantation (OR 19.8; 95%CI: 2.4-160.2) emerged as independent predictors for AGPN. A near-significant association was found for cytomegalovirus infection (OR 4.2; 95%CI: 0.9-18.4), whereas receiving a single-kidney transplant (vs. double-kidney) showed a protective effect (OR 0.2; 95%CI: 0.0-0.8). During the 36-month follow-up, levels of SC, creatinine clearance and 24-h proteinuria did not differ significantly between patients with or without AGPN, and this complication did not exert any effect on the risk for decline in renal graft function. AGPN does not impair long-term graft function in renal transplant recipients.

    Central venous access devices are extensively used for long-term chemotherapy and parenteral nutrition. However, there are some possible immediate, early, and late complications related to the implantation technique, care, and maintenance. We present the uncommon occurrence of a thrombosis of the internal jugular vein due to a spontaneous migration of a Port-A-Cath catheter into the ipsilateral internal jugular vein as a delayed complication of a central venous access catheter implanted for chemotherapy delivery. A review of the literature is given, and the factors responsible for this unusual complication will be discussed. PMID:19830037

    Purpose. To study the correlation between demographics and clinical variables and long-term severe visual impairment in patients with Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). Methods. A retrospective chart review of SJS/TEN patients between 2004 and 2014 was conducted. Demographics, causative agents, ocular manifestations, and visual outcomes were collected. The data were analyzed using a multivariate logistic regression model. Results. Of the 89 patients including SJS (65, 73.03%), TEN (15, 16.85%), and SJS-TEN overlap (9, 10.11%), 55 were female. The mean age was 41.58 ± 19.17 years. The most common identified agents were medications. Among these groups, antibiotics were the most prevalent (47.19%). Three patients (3.7%) had unknown etiology. Antibiotics and nonpharmaceutical triggers were significantly associated with long-term severe visual impairment (odds ratio 4.32; P = 0.015 and 7.20; P = 0.037, resp.). There was a significant negative relationship between HIV infection and long-term severe visual impairment (P = 0.021). Among all chronic ocular complications, only corneal neovascularization significantly correlated with severe visual impairment (P = 0.001). Conclusions. SJS/TEN patients caused by nonpharmaceutical triggers or antibiotics have an increased risk of developing long-term severe visual impairment from corneal neovascularization. HIV infection might be a protective factor against long-term poor visual outcomes.

    Advances in acute management and secondary prevention have reduced mortality and early recurrent risk after stroke and transient ischemic attack (TIA). However, whether improved outcomes are sustained long term among those without early adverse complications is not clear. We describe trends in long-term mortality and morbidity in patients with ischemic stroke or TIA who are clinically stable at 90 days. This is a longitudinal cohort registry study (2003-2013) of patients presenting to stroke centers in Ontario, Canada, with a stroke or TIA, with no hospitalization, stroke, myocardial infarction (MI), institutionalization, or death within 90 days (N = 26,698). Primary outcomes were 1-, 3-, and 5-year age-adjusted composite rates of death, stroke or MI, and institutionalization, and secondary analyses evaluated outcomes individually. Trend tests were used to evaluate change over time. One-year adjusted composite rates decreased from 9.3% in 2003 to 7.4% in 2012 (trend test P = .02). Significant decreases in 3-year (P < .001) and 5-year (P = .002) composite rates were also observed. Rates of recurrent stroke decreased at 1 and 3 years (P < .01), but not 5 years (P = .21), whereas death rates declined across follow-up times. Conversely, rates of institutionalization increased at 3 and 5 years (P < .01). Long-term mortality and morbidity post stroke and TIA have declined, confirming trends for improved long-term outcomes for patients clinically stable during the initial high-risk period. However, increased long-term rates of institutionalization also suggest that stroke and TIA patients are at risk of long-term functional decline, despite improved clinical outcomes. Further studies evaluating challenges for sustaining functional gains after stroke and TIA are required. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    We present current knowledge of bisphosphonate-associated osteonecrosis, a new oral complication in oncology. It was first described in 2003, and hundreds of cases have been reported worldwide. The disorder affects patients with cancer on bisphosphonate treatment for multiple myeloma or bone metastasis from breast, prostate, or lung cancer. Bisphosphonate-associated osteonecrosis is characterised by the unexpected appearance of necrotic bone in the oral cavity. Osteonecrosis can develop spontaneously or after an invasive surgical procedure such as dental extraction. Patients might have severe pain or be asymptomatic. Symptoms can mimic routine dental problems such as decay or periodontal disease. Intravenous use of pamidronate and zoledronic acid is associated with most cases. Other risk factors include duration of bisphosphonate treatment (ie, 36 months and longer), old age in patients with multiple myeloma, and a history of recent dental extraction. We also discuss pathobiology, clinical features, management, and future directions for the disorder.

    Long-term home parenteral nutrition (PN) is a potential risk for developing osteoporosis. Various attempts have been made to treat bone disease both by modifying the composition of PN and by administering hormones, such as calcitonin, parathyroid hormone, and sexual hormones. Bisphosphonates are recognized as a medication useful for the treatment of several bone disorders associated with excessive reabsorption. Nevertheless, there have been no paediatric studies on bisphosphonates use for intestinal failure-associated bone disease. Our study includes 6 paediatric patients receiving extremely long-term home PN (at least 3 years) who showed radiological and clinical signs of osteoporosis. Diagnosis of bone disease was made after a median period of 127.5 PN months. Treatment consisted in 2 cycles of intravenous pamidronate, 30 mg/m once per month for 6 months consecutively. They all showed a significant improvement in bone mineral density, evaluated after 6 and 12 months of pamidronate treatment. In our sample anthropometrical variables (weight, height, and body mass index) are not related with the z-score trend. Our patients had normal levels of calcium, phosphorus, and vitamin D, and proper nutrient intake. At the last follow-up, dual-energy x-ray absorptiometry scan showed that no patients had a z-score lower than -2.5; moreover, nobody developed bone fractures during the 108-month follow-up. The patients did not have any prominent adverse effect. Finally, in our experience, pamidronate is effective for improving bone mineral density and safe in patients with intestinal failure-associated bone disease.

    BACKGROUND: Secondary prevention after stroke and transient ischemic attack (TIA) has focused on high early risk of recurrence, but survivors of stroke can have substantial long-term morbidity and mortality. We quantified long-term morbidity and mortality for patients who had no early complications after stroke or TIA and community-based controls. METHODS: This longitudinal case–control study included all ambulatory or hospitalized patients with stroke or TIA (discharged from regional stroke centres in Ontario from 2003 to 2013) who survived for 90 days without recurrent stroke, myocardial infarction, all-cause admission to hospital, admission to an institution or death. Cases and controls were matched on age, sex and geographic location. The primary composite outcome was death, stroke, myocardial infarction, or admission to long-term or continuing care. We calculated 1-, 3- and 5-year rates of composite and individual outcomes and used cause-specific Cox regression to estimate long-term hazards for cases versus controls and for patients with stroke versus those with TIA. RESULTS: Among patients who were initially stable after stroke or TIA (n = 26 366), the hazard of the primary outcome was more than double at 1 year (hazard ratio [HR] 2.4, 95% confidence interval [CI] 2.3–2.5), 3 years (HR 2.2, 95% CI 2.1–2.3) and 5 years (HR 2.1, 95% CI 2.1–2.2). Hazard was highest for recurrent stroke at 1 year (HR 6.8, 95% CI 6.1–7.5), continuing to 5 years (HR 5.1, 95% CI 4.8–5.5), and for admission to an institution (HR 2.1, 95% CI 1.9–2.2). Survivors of stroke had higher mortality and morbidity, but 31.5% (1789/5677) of patients with TIA experienced an adverse event within 5 years. INTERPRETATION: Patients who survive stroke or TIA without early complications are typically discharged from secondary stroke prevention services. However, these patients remain at substantial long-term risk, particularly for recurrent stroke and admission to an institution. Novel

  17. Modelling Gaucher disease progression: long-term enzyme replacement therapy reduces the incidence of splenectomy and bone complications

    PubMed Central

    2014-01-01

    Long-term complications and associated conditions of type 1 Gaucher Disease (GD) can include splenectomy, bone complications, pulmonary hypertension, Parkinson disease and malignancies. Enzyme replacement therapy (ERT) reverses cytopenia and reduces organomegaly. To study the effects of ERT on long-term complications and associated conditions, the course of Gaucher disease was modelled. The cohort consisted of all diagnosed GD patients in the Netherlands. Mutually exclusive disease states were defined as ‘asymptomatic’, ‘signs/symptoms’, ‘recovery’, ‘splenectomy’, ‘bone complication’, ‘multiple complications’ and ‘malignancy’. A natural history (NH) cohort was delineated based upon historical data on Dutch patients before ERT was available. Cumulative incidence curves were composed for progression from each disease state to the next. Two scenarios were applied for the ERT cohort: time to complications was calculated from A. start of ERT; B. entering the previous disease state. Median time for the development of signs and/or symptoms was 30.1 years (N = 73). In the NH cohort (N = 42), 9% had developed a bone complication after 10 years in the signs/symptoms phase, while 21% had undergone a splenectomy. In the ERT cohort (N = 29 (A), N = 28 (B)), 12% (A) or 4% (B) had developed a bone complication after 10 years in this phase and no patient was splenectomized. No patients in the NH cohort recovered, compared to 50% in the ERT cohort after 3.6 years (N = 28 (A)) or 22.4 years (N = 27 (B)) of treatment. Median time from a first to a second complication was 11 years in the NH cohort (N = 31), whereas 16 respectively 14 percent had developed a second complication after 10 years in the ERT cohort (N = 17, scenario A/B). Fourteen percent (scenario A/B) developed an associated malignancy after 10 years in the phase ‘multiple complications’ (N = 23). Associated malignancies occurred almost exclusively in advanced disease stages, therefore it

    Purpose. Analysis of early vascular and nerve complications of supracondylar humerus fractures in children. Material and Methods. 220 children hospitalized in the Pediatric Trauma-Orthopedic Department in the years 2004-2014. The group consisted of 143 males and 77 females. Results. Acute neurovascular complications occurred in 16.81% of patients with displaced supracondylar fracture (37 children). Nerve damage was found in 10% of patients with displaced fracture (22 children). The most injured nerve was median nerve; this complication occurred in 15 patients (68.18%). The total nerve function returned after average of 122 days (0-220 days after surgery). Symptoms of vascular injury occurred in 7.7% children with displaced fracture (17 children). Conclusions. (1) In children with supracondylar fracture the most often injured nerve is median nerve. (2) The incidence of vascular and nerve complications positively correlates with the progression of fracture according to Gartland classification.

    Many pediatric urologic disorders have sequelae that may affect patients well into adulthood. Despite adequate treatment, many patients are at risk for progressive urologic deterioration years after surgical reconstruction. While many pediatric urologists follow their patients years after surgery, screening for late complications is a shared responsibility with primary care providers. This article discusses potential late complications and appropriate follow-up for patients who have a history of ureteral reimplantation, pyeloplasty, hypospadias repair, posterior urethral valve ablation, and intestinal interposition.

    Purpose: To evaluate the long-term safety, effectiveness, and prognostic factors of fractionated postoperative {beta}-irradiation. Methods and Materials: Between 1993 and 2005, 623 patients with 737 pterygium lesions were treated with a strontium-90 eye applicator after surgical excision. The median follow-up period was 60 months (range, 6.7-139.5). Of the 737 lesions, 644 were primary and 93 were recurrences after surgical removal alone. Fractionated radiotherapy (RT) to a total dose of 35 Gy in five to seven fractions was used. Results: A total of 73 local pterygium recurrences (9.9%) were noted. Of the recurrent cases, 80% were noted within 3 years after treatment. The 5- and 10-year probability of local control was 90% and 88%, respectively. The multivariate analysis for all cases demonstrated that gender, age, total radiation dose, recurrent pterygia, and interval between surgery and RT affected the overall local control rate. Late toxicities that might have been associated with strontium-90 RT included scleromalacia (scleral thinning) in nine eyes, adhesion of the eyelids in eight, cataracts in six, and scleral ulcer in five eyes. Conclusion: Fractionated strontium-90 RT to a total dose of approximately 35 Gy in five to seven fractions results in a similar local control rate as higher doses in other series, with an acceptable complication rate.

    Transplant tourism, a form of transplant commercialization, has resulted in serious short-term adverse outcomes that explain reduced short-term kidney allograft survival. However, the nature of longer-term outcomes in commercial kidney transplant recipients is less clear. To study this further, we identified 69 Canadian commercial transplant recipients of 72 kidney allografts transplanted during 1998 to 2013 who reported to our transplant center for follow-up care. Their outcomes to 8 years post-transplant were compared with 702 domestic living donor and 827 deceased donor transplant recipients during this period using Kaplan-Meier survival plots and multivariate Cox regression analysis. Among many complications, notable specific events included hepatitis B or C seroconversion (7 patients), active hepatitis and/or fulminant hepatic failure (4 patients), pulmonary tuberculosis (2 patients), and a type A dissecting aortic aneurysm. Commercial transplantation was independently associated with significantly reduced death-censored kidney allograft survival (hazard ratio 3.69, 95% confidence interval 1.88-7.25) along with significantly delayed graft function and eGFR 30 ml/min/1.73 m(2) or less at 3 months post-transplant. Thus, commercial transplantation represents an important risk factor for long-term kidney allograft loss. Concerted arguments and efforts using adverse recipient outcomes among the main premises are still required in order to eradicate transplant commercialization.

    Introduction. As it is well known, High Intensity Focused Ultrasound (HIFU) is a minimally invasive procedure for prostate cancer. Many investigators reported their series of patients, demonstrating the effectiveness of the treatment. The most majority of Authors, however, do not report the side effects and the complications of the procedure, which is the aim of our study. The diagnosis and management of complications is discussed, and the oncologic outcome is reported in terms of quality of life. Materials and Methods. We report our experience in 89 patients, low-, intermediate-, and high-risk patients according with D'Amico classification. All data collected along the study were analyzed, including side effects and complications of the procedure. Results. Our series demonstrates the effectiveness of the procedure, in line with larger series reported in literature by other investigators. The most important side effects are sexual function impairment and transient incontinence in a minority of cases. Minor complications are reported as well as rare cases of major complications, which can require surgical treatment. PMID:22927842

    Due to its short duration of therapy and low rates of local recurrence, women undergoing breast conservation are increasingly opting for partial breast irradiation with the MammoSite (Cytyc/Hologic) catheter. In early follow-up studies, few complications were reported. Few data, however, exist regarding longer-term complications. We compared the long-term local toxicities of MammoSite partial breast irradiation with those resulting from whole breast radiation. This was a retrospective study performed in a single academic medical center. All patients who underwent breast-conserving surgery between 2003 and 2008, who met institutional criteria for brachytherapy, were included. We compared women treated with MammoSite with patients treated with whole breast radiation therapy (WBRT). Endpoints included incidence of palpable masses at the lumpectomy site, telangiectasias, and local recurrence. Seventy-one MammoSite patients and 245 WBRT patients were well matched with regard to clinical characteristics. Median follow-up was 4 years. A palpable mass developed at the site of lumpectomy in 27% of the MammoSite patients compared with 7% of the WBRT patients (p < 0.0001). Telangiectasias developed more frequently in the MammoSite group than in the WBRT group (24% vs 4%, p < 0.001). Forty-two percent of patients treated with MammoSite developed a palpable mass, telangectasia, or both. Palpable masses and telangiectasias are frequent long-term complications after MammoSite brachytherapy and occur at a significantly higher rate after MammoSite brachytherapy than after WBRT. This increased rate of long-term local toxicity should be considered when counseling women on options for adjuvant radiation therapy after breast-conserving surgery.

    The silicon-rubber T-tube was applied to 181 ears in 116 patients with chronic otitis media with effusion within last 5 years. Among the 181 ears, 81 (46%) accepted the T-tube without problems. In the remaining 97 ears, complications such as otorrhea, occlusion of the tube, extrusion of the tube, enlarged perforation and cholesteatoma occurred. However, in 161 ears (89%), the tube could be stabilized in the middle ear and functioned as ventilating tube beyond 3 months. Based on the incidence and prognosis of the ears with the complications and the results of hearing, we conclude that insertion of the T-tube is valuable and reliable method of treatment in the ears with retractions or atelectasis but in the ears with adhesion or granulation, this method of treatment has only limited value.

    Valid data on acromegaly incidence, complications and mortality are scarce. The Danish Health Care System enables nationwide studies with complete follow-up and linkage among health-related databases to assess acromegaly incidence, prevalence, complications and mortality in a population-based cohort study. All incident cases of acromegaly in Denmark (1991-2010) were identified from health registries and validated by chart review. We estimated the annual incidence rate of acromegaly per 10(6) person-years (py) with 95% confidence intervals (95% CIs). For every patient, 10 persons were sampled from the general population as a comparison cohort. Cox regression and hazard ratios (HRs) with 95% confidence intervals (95% CIs) were used. Mean age at diagnosis (48.7 years (CI: 95%: 47.2-50.1)) and annual incidence rate (3.8 cases/10(6) persons (95% CI: 3.6-4.1)) among the 405 cases remained stable. The prevalence in 2010 was 85 cases/10(6) persons. The patients were at increased risk of diabetes mellitus (HR: 4.0 (95% CI: 2.7-5.8)), heart failure (HR: 2.5 (95% CI: 1.4-4.5)), venous thromboembolism (HR: 2.3 (95% CI: 1.1-5.0)), sleep apnoea (HR: 11.7 (95% CI: 7.0-19.4)) and arthropathy (HR: 2.1 (95% CI: 1.6-2.6)). The complication risk was also increased before the diagnosis of acromegaly. Overall mortality risk was elevated (HR: 1.3 (95% CI: 1.0-1.7)) but uninfluenced by treatment modality. (i) The incidence rate and age at diagnosis of acromegaly have been stable over decades, and the prevalence is higher than previously reported. (ii) The risk of complications is very high even before the diagnosis. (iii) Mortality risk remains elevated but uninfluenced by mode of treatment. © 2016 European Society of Endocrinology.

    This article examines factors within the long-term-care work environment that impact the effectiveness of continuing education. In Study 1, focus group interviews were conducted with staff and management from urban and rural long-term-care facilities in southwestern Ontario to identify their perceptions of the workplace factors that affect transfer of learning into practice. Thirty-five people were interviewed across six focus groups. In Study 2, a Delphi technique was used to refine our list of factors. Consensus was achieved in two survey rounds involving 30 and 27 participants, respectively. Management support was identified as the most important factor impacting the effectiveness of continuing education. Other factors included resources (staff, funding, space) and the need for ongoing expert support. Organizational support is necessary for continuing education programs to be effective and ongoing expert support is needed to enable and reinforce learning.

    The aim of this study was to evaluate the endocrinological complications of the patients with thalassemia major (TM) who underwent bone marrow transplantation (BMT) and followed-up more than two years in our center, prospectively. "BMT group" consisted of 41 patients with TM. The mean age was 12.4 ± 5.4 years and transplantation age was mean 7.5 ± 4.9 years. Post-BMT follow-up lasted from 24 to 122 months (mean 65.07 months). Also, 32 TM patients with similar age group and same history of transfusion and chelation therapy were recruited for the study as "control (C) group". The weight SDS score after transplantation was found better than before transplantation (p = 0.010). There was a negative correlation between height SDS and BMT age (p = 0.008). The height SDS scores were better in patients whose BMT age was under seven years old compared to those older than seven years old (p = 0.02). Z-scores of femur neck and L2-4 vertebrae DEXA were decreased (p = 0.032, p = 0.0001) and incidence of insulin resistance increased (p = 0.01) in patients with increased BMT age. The risk of gonadal insufficiency was significantly lower in the patients who underwent BMT <7 years of age (p = 0.009). There was no statistically significant relationship between BMT age and complications such as hypothyroidism, hypoparathyroidism, and adrenal insufficiency. The patients with TM should be evaluated for transplantation in early stage of the disease, especially before the age of seven years. Because the BMT cannot correct the endocrinological complications of TM completely, the patients should be followed up regularly after the transplantation.

    Bezoars are uncommon diseases caused by the presence of indigestible mass of strange material in the gastrointestinal tract. Gold-standard treatment remains unclear and there are not clinical guidelines to follow. We present a very rare case of 53-year-old man suffering phytobezoar in a gastroplasty after oesophagectomy due to aloe vera ingestion as natural medicine. Finally it was solved with cellulase. Therefore, this is a scarcely complication after esophagectomy. Cellulase is a very good option to treat phytobezoar avoiding reintervention in this kind of patient. PMID:26094056

    The incidence of non-obstetrical complications after cervical conization is low, and women receive minimal postsurgical attention. In this study, we investigated whether women felt any discomfort after undergoing conization by harmonic scalpel, one of the hot-knife devices widely used in Japan. Eighty-eight women aged 20-47 years who were still experiencing menstrual cycles and had undergone harmonic conization participated in a questionnaire survey regarding perisurgical complications and postsurgical changes in gynecological issues. Correlations between the occurrence of postoperative complications and clinical characteristics were analyzed. Regarding the complications immediately after the surgery, 37 women (45.1%) complained of postoperative bleeding that was heavier than their usual menstrual bleeding, and 14 (18.2%) reported that the postsurgical bleeding was greater than they had expected. Regarding long-term gynecological changes after conization, 27 women (30.7%) reported that the duration of menstrual bleeding had increased after the surgery, 20 (22.7%) indicated that pain during menstruation had changed, and 40 (45.5%) stated that the amount of menstrual bleeding had changed. Irregular genital bleeding outside of menstruation appeared in 23 women (26.4%). Additionally, 24 (27.6%) of the women reported that the conization procedure negatively impacted their quality of life. Finally, the occurrence of long-term atypical bleeding after the surgery was significantly correlated with the thickness and circumference of the tissue specimen. Several women experienced a significant change in quality of life after harmonic conization. Women who undergo conization should receive a comprehensive preoperative overview of the procedure and attentive postsurgical care. © 2017 Japan Society of Obstetrics and Gynecology.

  15. Temperamental factors predict long-term modifications of eating disorders after treatment

    2013-01-01

    Background Eating Disorders (EDs) are complex psychiatric pathologies characterized by moderate to poor response to treatment. Criteria of remission and recovery are not yet well defined. Simultaneously, personality plays a key role among the factors that determine treatment outcome. The aim of the present research is to evaluate the possibility of temperamental and character traits to predict the long-term outcome of ED. Method A sample of 25 AN and 28 BN female patients were re-assessed face-to-face after a minimum 5-years-follow-up through SCID-I, EDI-2 and TCI-R. Regression Analyses were performed to ascertain the possibility of TCI-R dimensions at the first visit to predict the long-term outcome. Results Clinical and psychopathological symptoms significantly decreased over the time and 23% of participants no longer received a categorical ED diagnosis after at least 5 years of follow-up. TCI-R dimensions failed to predict the absence of a DSM-IV-TR diagnosis in the long term, but Novelty Seeking, Harm Avoidance and Reward Dependence demonstrated to predict the clinical improvement of several EDI-2 scales. Conclusions Our results support the idea that temperamental dimensions are relevant to the long-term improvement of clinical variables of ED. Low Novelty Seeking is the strongest predictor of poor outcome. PMID:24200241

    Background Female genital mutilation/cutting (FGM/C) is a harmful traditional practice deeply rooted in 28 Sub-Saharan African countries. Its prevalence in The Gambia is 76.3%. The objective of this study was to gain precise information on the long-term health consequences of FGM/C in The Gambia as well as on its impact on delivery and on the health of the newborns. Methods Data were collected from 588 female patients examined for antenatal care or delivery in hospitals and health centers of the Western Health Region, The Gambia. The information collected, both through a questionnaire and medical examination, included sociodemographic factors, the presence or not of FGM/C, the types of FGM/C practiced, the long-term health consequences of FGM/C, complications during delivery and for the newborn. Odds ratios, their 95% confidence intervals, and P values were calculated. Results The prevalence of patients who had undergone FGM/C was 75.6% (type I: 75.6%; type II: 24.4%). Women with type I and II FGM/C had a significantly higher prevalence of long-term health problems (eg, dysmenorrhea, vulvar or vaginal pain), problems related to anomalous healing (eg, fibrosis, keloid, synechia), and sexual dysfunction. Women with FGM/C were also much more likely to suffer complications during delivery (perineal tear, obstructed labor, episiotomy, cesarean, stillbirth) and complications associated with anomalous healing after FGM/C. Similarly, newborns were found to be more likely to suffer complications such as fetal distress and caput of the fetal head. Conclusion This study shows that FGM/C is associated with a variety of long-term health consequences, that women with FGM/C are four times more likely to suffer complications during delivery, and the newborn is four times more likely to have health complications if the parturient has undergone FGM/C. These results highlight for the first time the magnitude of consequences during delivery and for the newborn, associated with FGM

    To evaluate the effectiveness and safety of anti-tumor necrosis factor therapy in patients with amyloid A amyloidosis. Multicenter, controlled, dynamic prospective cohort study of 36 patients with amyloid A amyloidosis (94% kidney involvement) treated with anti-tumor necrosis factor agents (drug exposure of 102.97 patient-years). As an external control group, 35 propensity score-matched non-amyloid patients were chosen from the Base de Datos de Productos Biológicos de la Sociedad Española de Reumatología registry. The end points were kidney response and progression, anti-tumor necrosis factor continuation rate, patient survival, and adverse events. At the end of follow-up, a kidney response was observed in 12 of 22 patients (54.5%) and a kidney progression was observed in 6 of 36 patients (17%). The kidney amyloidosis remained stable in 16 of 36 patients (44%). The level of acute phase reactants diminished but did not reach the normal level. The continuation rates of anti-tumor necrosis factor drugs among patients with amyloid A amyloidosis after 1, 2, 3, and 4 or more years were 80%, 80%, 61%, and 52%, respectively, comparable to controls. The 5-year cumulative survival of amyloid A amyloidosis cases was 90.6%, and the 10-year survival was 78.5%. In a multivariate Cox regression analysis, the duration of amyloidosis and the level of proteinuria at the onset of anti-tumor necrosis factor treatment were independent predictors of treatment failure, whereas the level of proteinuria was the only factor that predicts mortality. Most adverse events were similar in both groups, although the number of infections was 3 times higher in amyloid A amyloidosis cases. Anti-tumor necrosis factor drugs are effective in treating amyloid A amyloidosis, although they might increase the risk of infection. Copyright 2010 Elsevier Inc. All rights reserved.

    To evaluate the progression of arterial hypertension (AH) and its consequences, in patients submitted to cardiac transplantation (CT) in use of cyclosporine (CY). In 65 patients submitted to orthotopic CT, we evaluated blood pressure, serum creatinine and blood levels of CY before, 15 and 30 days, and 6, 12, 24, 48 and 60 months after CT; in 20 patients we analyzed cardiac index and systemic vascular resistance pre-CT, 15 and 30 days, 6 and 12 months after CT; in 33 patients, we studied anatomic and functional modifications by echocardiography, 24 +/- 13 months after CT. Thirty days after CT, AH was present in 58.5% (50% mild), and after one year, 93% of patients were hypertensives (85% moderate-to-severe), remaining unchanged during the rest of follow-up. The serum creatinine progressively increased, reaching values significantly higher than those pre-CT after one year, persisting with a mild increment until 60 months. Echocardiography showed left ventricle hypertrophy in 54% of patients, all of which had normal function. Two patients died as a direct consequence of hypertensive complications. AH in patients submitted to CT on CY use occurs early, increases in prevalence and severity during the follow-up and is mediated by an increase in vascular resistance. Also, the AH does not correlate to CY blood levels or nefrotoxicity, but it can impair renal function and compromise longevity of transplantation by inducing ventricular hypertrophy.

    A series of 31 Parkinson's disease (PD) patients suffering from panic attacks (PA), late in the evolution of their disease, was analyzed from a group of 131 levodopa-treated PD patients. We found that many of motor, sensory, and vegetative symptoms, previously described as complicating phenomena in PD, constituted some of the symptoms of panic disorders. Comparing PA series with the series of PD patients who did not complain of PA, we discovered a clear-cut relationship of PA with the presence of standing/gait troubles (p < 0.001), depression (p < 0.001), and dyskinesias/fluctuations (p < 0.001). The patients of the PA series also presented a more precocious age of PD onset, were put on levodopa therapy earlier, and needed to be treated with higher doses of levodopa than the patients without PA. Finally, we hypothesize that PA could be considered to be a sort of abstinence syndrome from levodopa, because they appears mostly (90.3%) in the OFF phase of fluctuations, and are relieved administering new doses of levodopa or dopaminergic agonists. Nevertheless, we suggest PA are not directly related to the pharmacological properties of levodopa, but to alterations of the noradrenergic systems in the CNS.

    Background Sickle cell disease is a genetic haemoglobin disorder, which can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Sickle cell disease is one of the most common severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. The two most common chronic chest complications due to sickle cell disease are pulmonary hypertension and chronic sickle lung disease. These complications can lead to morbidity (such as reduced exercise tolerance) and increased mortality. This is an update of a Cochrane review first published in 2011 and updated in 2014. Objectives We wanted to determine whether trials involving people with sickle cell disease that compare regular long-term blood transfusion regimens with standard care, hydroxycarbamide (hydroxyurea) any other drug treatment show differences in the following: mortality associated with chronic chest complications; severity of established chronic chest complications; development and progression of chronic chest complications; serious adverse events. Search methods We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group’s Haemoglobinopathies Trials Register. Date of the last search: 25 April 2016. We also searched for randomised controlled trials in the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 26 January 2016), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950), and ongoing trial databases to 26 January 2016. Selection criteria We included randomised controlled trials of people of any age with one of four common sickle cell disease genotypes, i.e. Hb SS, Sß0, SC, or Sß+ that compared regular red blood cell transfusion regimens (either simple or exchange transfusions) to hydroxycarbamide, any other drug treatment, or to standard care that were aimed at reducing the development or progression of chronic chest

    Traumatic hip dislocations can have devastating complications such as osteoarthritis or osteonecrosis. The aim of this study was to identify the variables and prognostic factors associated with clinical and radiological outcome after a traumatic hip dislocation at long-term follow-up. A review was performed of all dislocations and fracture-dislocations of the hip from January 1999 to December 2012. A computed tomography scan was performed after reduction in all cases. The Harris Hip Score and modified Merle-d'Aubigné-Postel method were used for clinical evaluation and radiological assessment was performed according to the Thompson and Epstein classification. There were 30 cases in 29 patients with a mean follow-up of 11 years (range, 4-17). The great majority were simple dislocations (21; 70%) vs. complex dislocations (9; 30%). Closed reduction was performed in less than 6h in all except one case (29; 96.7%). All of the patients with simple dislocations had an excellent outcome without radiological signs of osteoarthritis at the end of the follow-up (P<.01). Overall, arthritic signs had developed in 4 patients (13.3%) and avascular necrosis was noted in 3 patients (10%). Five patients with intraarticular fragments were treated non-operatively, and 3 of them developed arthritic changes (P<.05). Our study suggests that complex dislocations are associated with poorer functional and radiological outcomes than simple dislocations. We also found a strong association between intraarticular fragments and osteoarthritis, so surgical fragment removal could be considered in these cases. Copyright © 2017 SECOT.

    This study applied a modified version of the extended technology acceptance model (TAM2) to examine the factors determining the acceptance of health IT applications by caregivers in long-term care facilities. The antecedent variables, including social influence factors such as subjective norm and image were examined together with demographic variables including age, job level, long-term care work experience and computer skills in regard to their impact on caregivers' acceptance of health IT applications. A self-administered questionnaire was developed based on the validated items from TAM2. The data was collected in a cross-sectional survey using convenience sample. Confirmatory factor analysis and structural equation modelling techniques were used to validate our causal model. Perceived usefulness, perceived ease of use and computer skills had significant positive impact, whereas image had significant negative impact on caregivers' intention to use health IT applications. Image, subjective norm and computer skills also indirectly impacted on intention through the mediating factor of ease of use. Ease of use, subjective norm and job level also determined perceived usefulness. The other demographic factors (including age and long-term care work experience) did not have any significant effect on caregivers' acceptance of a health IT application. Our model explains 34% of caregivers' intention to use an introduced IT application before any hands-on experience with the system established. The planners and managers should ensure that a health IT application to be introduced into a long-term care facility is useful and easy to use. Effort should be focused on forming a positive social norm for the introduction of the new innovation and improving caregivers' computer skills. Securing the managers' and senior nurses' support for the innovation at the onset of the project is critical for success. Finally the caregivers appear to dislike the idea of increased IT ability will

    Augmentation or reconstruction of the calves is indicated in patients with thin legs, for bodybuilders, or when there is a defect after an injury or illness. The principle of placing implants under the investing crural fascia was worked out in the 1980s. The senior author (I.N.) introduced many technical modifications and improvements for this operation, among them the new instrument, an inserter for the calf implants. Presented patient material is unique in that the more challenging reconstructive cases almost equal the numbers of the aesthetic cases. During the years 1991 through 2016, 50 patients underwent 60 calf contour corrections. Indications were aesthetic in 23 patients, six were bodybuilders, and 21 underwent lower leg reconstruction because of deformity caused by illness. According to evaluation by the surgeon, excellent-to-good results were obtained in 30 out of 37 followed patients. Patients rated their results as very good (18), good (10), acceptable (7) and bad (2). One 28-year-old professional bodybuilder sustained acute anterior compartment syndrome in one leg. Implants were removed 16 h after surgery, but he developed ischaemia in the anterior compartment leading to the necrosis of muscles. After several surgical operations, including microsurgical transfer of the innervated central caput of the quadriceps femoris muscle, he could resume his bodybuilding activities. Other complications were minor and manageable. Calf augmentation, performed properly, has evolved to be a safe, efficient and aesthetically pleasing operation. The possibility of acute compartment syndrome should be kept in mind. This journal requires that authors assign a level of evidence to each article.

    2016-03-01

    In this review, we identified 15 studies in children and 10 studies in adults that assessed the association between long-term exposure to air pollution and incident asthma and that conducted stratified analyses to explore potential susceptibility factors. Overall, adult never-/former smokers seem to be at higher risk of incident asthma due to air pollution. Children without atopy and children from low socioeconomic status families also seem to be at higher risk of incident asthma due to air pollution. While interaction between air pollution and genes involved in the response to oxidative stress pathways have been explored, results are somewhat inconsistent and in need of replication. To evaluate interactions, large sample sizes are necessary, and much more research, including data pooling from existing studies, is needed to further explore susceptibility factors for asthma incidence due to long-term air pollution exposure.

    Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm²/m² for women and 40.8 cm²/m² for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P < 0.001), but not for total complications. However, sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P < 0.001) and disease-free survival (HR = 1.620, P < 0.001). Under the adjusted tumor-node-metastasis (TNM) stage, sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover, sarcopenia

    The long-term efficacy of tolvaptan, a vasopressin V2 receptor antagonist, has been reported. However, the safety of long-term treatment remains to be fully elucidated. We assessed the safety profile of tolvaptan with respect to hypernatremia. This retrospective study included 371 patients treated with tolvaptan. Risk factors for hypernatremia (serum sodium concentration ≥147 mEq/L) were determined. Hypernatremia occurred in 95 patients (25.6 %), of whom 71 (19.1 %) developed hypernatremia within 7 days of tolvaptan treatment (early onset). Stepwise logistic regression analysis demonstrated that baseline serum sodium ≥140 mEq/L, an initial tolvaptan dosage >7.5 mg, and a BUN/serum creatinine ratio ≥20 were independent risk factors for early onset of hypernatremia. Tolvaptan was prescribed for more than 7 days to 233 patients, of whom 123 were administrated tolvaptan for more than 1 month. Hypernatremia occurred in 24 of these patients (10.3 %) (late onset). Predictive factors for late onset of hypernatremia were an average daily dosage of tolvaptan >7.5 mg and age ≥75 years. A daily dosage of 7.5 mg or less was recommended to prevent hypernatremia in short- as well as long-term tolvaptan treatment, and mainly elderly patients were at risk for hypernatremia.

    Turoctocog alfa pegol (N8-GP) is a glycoPEGylated human recombinant factor VIII for the treatment of hemophilia A. The safety profile of rFVIII, and polyethylene glycols (PEG) technology, is well-established. Conducting long-term toxicity studies in animals using human proteins can be complicated by anti-drug antibody (ADA) development. To evaluate long-term safety of N8-GP, 26- and 52-week toxicity studies were conducted in immune-deficient rats dosed intravenously every fourth day with 0, 50, 150, 500, or 1200 IU/kg N8-GP. Observations included clinical observations, body weight, ophthalmoscopy, hematology, chemistry, coagulation, urinalysis, toxicokinetics, antibody analysis, and macroscopic/microscopic organ examination. Immunohistochemical staining examined the distribution of PEG in the brain. No adverse test item-related findings were seen and PEG was not detected in the brain. Exposure was confirmed for ~75% of the animals dosed with 500 and 1200 IU/kg N8-GP; the high lower limit of quantification of the bioanalysis assay prevented confirmation of exposure in the lower doses. A small number of animals developed ADAs, and the proportion of animals surviving until scheduled termination was >80%. N8-GP was well tolerated, and the immune-deficient rat proved suitable for testing long-term toxicity of human proteins that are immunogenic in animals. PMID:28458688

    Background There are few long-term outcome reports of unilateral lateral rectus (LR) recession for exotropia including a large number of subjects. Previous reports on unilateral LR recession commonly show extremely low rates of initial overcorrection and large exodrifts after surgery suggesting that the surgical dose may be increased. However, little is known of the long-term outcome of a large unilateral LR recession for exotropia. Objectives To determine long-term outcomes and predictive factors of recurrence after a large unilateral LR recession in patients with exotropia. Data Extraction Retrospective analysis was performed on 92 patients aged 3 to 17 years who underwent 10 mm unilateral LR recession for exotropia of ≤ 25 prism diopters (Δ) with prism and alternate cover testing and were followed up for more than 2 years after surgery. Final success rates within 10Δ of exophoria/tropia and 5Δ of esophoria/tropia at distance in the primary position, improvement in stereopsis and the predictive factors for recurrence were evaluated. Results At 24 months after surgery, 54% of patients had ocular alignment meeting the defined criteria of success, 45% had recurrence and 1% had overcorrection. After a mean follow-up of 39 months, 36% showed success, 63% showed recurrence and 1% resulted in overcorrection. The average time of recurrence was 23.4±14.7 months (range, 1–60 months) and the rate of recurrence per person-year was 23% after unilateral LR recession. Predictive factors of recurrence were a larger preoperative near angle of deviation (>16Δ) and larger initial postoperative exodeviation (>5Δ) at distance. Conclusions Long-term outcome of unilateral LR recession for exotropia showed low success rates with high recurrence, thus should be reserved for patients with a small preoperative near angle of exodeviation.

    Objectives Chronic hepatitis C (CHC) is a major public health problem in Puerto Rico. It is the most common cause of chronic liver disease and the most frequent indication for liver transplantation in the United States." Our main objectives were to estimate the seroprevalence of CHC infection, to describe the demographic and histological parameters of the infection in our sample population, and to evaluate the treatment outcomes in Puerto Rican veterans. Methods To determine overall seroprevalence, we reviewed all the hepatitis C cases (encompassing from January 1, 2002, to December 31, 2009) of the VA Caribbean Healthcare System, Department of Veterans Affairs. The records of only those individuals who received treatment with pegylated interferon and ribavirin were reviewed to determine risks factors for infection, response rates, adverse events, and outcomes. Results During the study period, there were a total of 1,496 patients identified as being infected with HCV, for an estimated seroprevalence of 2.3%. Of these, approximately 10% (137) were treated with combination therapy and were included in this study. The mean age was 58 (±6.4); 96.4% were men. The most common genotype was type 1. The responses to treatment were generally poor, with only 48.4% of the patients achieving Ssustained virological response. Discussion Though the seroprevalence of chronic hepatitis C in the Latino veteran population of Puerto Rico is high, relatively few patients have received treatment, most probably because of the contraindications of the medications used. Combination therapy with pegylated interferon plus weight-based ribavirin was inefficient and plagued with side effects; as a whole, this therapy was not found to be overly beneficial to our patients. New emerging and approved therapies will change this paradigm, allowing the treatment of a larger population without the side effects of the studied therapy. PMID:26932282

    The long-term future of species composition in forests depends on regeneration. Many factors can affect regeneration, including human use, environmental conditions, and species’ traits. This study examines the influence of these factors in a tropical deciduous forest of Central India, which is heavily used by local, forest-dependent residents for livestock grazing, fuel-wood extraction, construction and other livelihood needs. We measure size-class proportions (the ratio of abundance of a species at a site in a higher size class to total abundance in both lower and higher size classes) for 39 tree species across 20 transects at different intensities of human use. The size-class proportions for medium to large trees and for small to medium-sized trees were negatively associated with species that are used for local construction, while size class proportions for saplings to small trees were positively associated with those species that are fire resistant and negatively associated with livestock density. Results indicate that grazing and fire prevent non-fire resistant species from reaching reproductive age, which can alter the long term composition and future availability of species that are important for local use and ecosystem services. Management efforts to reduce fire and forest grazing could reverse these impacts on long-term forest composition.

    The aim of this study was to evaluate metabolic risk factors and their impact on long-term allograft function in paediatric renal transplant (RTx) patients. We reviewed the medical records of 210 RTx patients who underwent transplantation at a median age of 4.5 years (range 0.7-18.2) and a median follow-up of 7.0 years (range 1.5-18.0). Data on lipid and glucose metabolism, uric acid levels, weight and blood pressure were collected up to 13 years post-RTx, and the findings were correlated with the measured glomerular filtration rate (GFR). Beyond the first year, GFR showed gradual deterioration with a mean decline of 2.4 ml/min/1.73 m(2)/year. Metabolic syndrome, overweight, hypertension and type 2 diabetes were diagnosed in 14-19%, 20-23%, 62-87% and 3-5% of the patients, respectively. These entities showed only mild association with the concomitant or long-term GFR values. Dyslipidaemia was common and hypertriglyceridaemia associated with a lower GFR at 1.5 and 5 years post-RTx (P = 0.008 and P = 0.017, respectively). Similarly, hyperuricaemia was frequent and associated significantly with GFR (P < 0.001). Except for hyperuricaemia and hypertriglyceridaemia, metabolic risk factors beyond the first postoperative year associated modestly with the long-term kidney graft function in paediatric RTx patients.

    This study was designed to report the long-term complications of iris-claw phakic intraocular lens implantation in a patient with Weill-Marchesani syndrome. Case report and literature review. A 26-year-old man with a history of glaucoma had bilateral phakic lens implantation for high myopia 10 years previously. Two years later, the left implant dislocated and was repositioned. Slit-lamp examination of both eyes revealed phakic implants of the iris-claw variety. There were moderate iridocorneal adhesions in the areas in which the lens haptics pinched the iris in both eyes and moderate epithelial and stromal edema over the temporal one-third of the left cornea. The crystalline lenses were clear with 3+phacodonesis OU. Dilated fundus examinations revealed bilateral severe optic nerve cupping. Crystalline lens diameters were measured at 7.5mm in the right eye and 8 mm in the left. Anterior chamber depths were 2.63 mm OD and 2.40 mm OS. Specular microscopy revealed central endothelial cell counts of 1133 and 587 cells/mm OD and OS, respectively. Axial lengths were 23.3 mm OD and 25 mm OS. Gonioscopic examination revealed bilateral angle closure with marked peripheral anterior synechiae. Based on our findings of short stature, shortened and thickened fingers, relatively normal axial length, microspherophakia, high myopia, and glaucoma, we diagnosed the patient with Weill-Marchesani syndrome. Iris claw-lens phakic lenses may be an effective surgical alternative to correct high myopia in select patients; however, it may produce long-term complications in eyes with specific features.

    Background and Objectives Some patients with Kawasaki disease (KD) develop large coronary aneurysms and subsequent coronary stenosis or obstruction, leading to ischemic heart disease. This study examined the long-term outcomes of patients with KD complicated by large coronary aneurysms. Subjects and Methods The medical records of 71 patients (53 men and 18 women) diagnosed with large coronary aneurysms (diameter ≥6 mm) between December 1986 and December 2013 were retrospectively reviewed from our institutional database. Results The mean age at onset was 4.6±3.3 years, and the mean follow-up duration was 12.5±6.9 years. Maximum coronary artery internal diameter ranged from 6.1 to 25 mm. Giant coronary aneurysms occurred in 48 patients and coronary aneurysms 6-8 mm in diameter developed in 23 patients. Coronary stenosis and/or complete occlusion occurred in 30 patients (42.3%). Catheter and/or surgical interventions (mean: 1.5 interventions, range: 1-5 interventions) were performed in 20 patients (28.2%), 9 months to 18 years after KD onset, resulting in 33.7% cumulative coronary intervention rates at 20 years after onset. There were no differences in cumulative coronary intervention rates between two coronary aneurysm groups (6-8 mm vs. ≥8 mm). Myocardial infarction occurred in 7 patients with a giant aneurysm and there was one death. Conclusions Long-term survival of patients with KD complicated by large coronary aneurysm was good even though 28.2% of patients underwent multiple catheter or surgical interventions. Careful follow-up is also necessary in KD patients with coronary aneurysms 6-8 mm in diameter, such as those with giant aneurysms. PMID:28765744

    Objective To examine a prevailing conceptual model of health services use (Andersen 1995) and to suggest modifications that may enhance its explanatory power when applied to empirical studies of race/ethnicity and long-term care. Study Setting Twelve focus groups of African-American (five groups) and white (seven groups) individuals, aged 65 and older, residing in Connecticut during 2000. Study Design Using qualitative analysis, data were coded and analyzed in NUD-IST 4 software to facilitate the reporting of recurrent themes, supporting quotations, and links among the themes for developing the conceptual framework. Specific analysis was conducted to assess distinctions in common themes between African-American and white focus groups. Data Collection Data were collected using a standardized discussion guide, augmented by prompts for clarification. Audio taped sessions were transcribed and independently coded by investigators and crosschecked to enhance coding validity. An audit trail was maintained to document analytic decisions during data analysis and interpretation. Principal Findings Psychosocial factors (e.g., attitudes and knowledge, social norms, and perceived control) are identified as determinants of service use, thereby expanding the Andersen model (1995). African-American and white focus group members differed in their reported accessibility of information about long-term care, social norms concerning caregiving expectations and burden, and concerns of privacy and self-determination. Conclusions More comprehensive identification of psychosocial factors may enhance our understanding of the complex role of race/ethnicity in long-term care use as well as the effectiveness of policies and programs designed to address disparities in long-term care service use among minority and nonminority groups.

    Little information is available about long-term results after adult liver transplantation. This study analyses long-term medical complications, changes of immunosuppression, recurrence of primary disease and quality of life 10 years after liver transplantation. During the period February 1984-April 1994, 324 LT were performed in 282 adults (>15 years). One hundred forty-seven (52%) patients survived more than 10 years. Data regarding health status of 103 patients exclusively followed-up in our institution were analyzed. Actual 1, 5, 10 years survival rates of the 282 recipients were 76.6%, 64.9% and 52% respectively. Forty eight (46.6%) of the 103 studied patients had normal liver tests in their tenth year of the follow-up. Seventy-one (69%) patients were on a CyA, TAC or MMF monotherapy; 31 (30%) patients had CyA levels of less than 100ng/ml. Forty five patients had recurrent allograft disease. Twenty-four (40.6%) of 59 liver biopsy available at 10th year were normal. Thirty five (34%) patients developed chronic renal failure; nine (8.7%) of them had end-stage renal disease. New onset hypertension (>140/100 mmHg) developed in 49 (47.6%) patients; fourteen (13.6%) developed diabetes (glucose blood level > 140 mg/dl) and twenty five (24.2%) patients had serious cardiovascular events. Thirteen (12.6%) patients had a BMI>28 and thirty six (35%) patients had elevated serum cholesterol (>220 mg/dl). Cataract was present in 8 (7.7%) patients. De novo malignancy developed in 23 (22.3%) patients. One patient each developed nasopharyngeal lymphoproliferative disease and myeloma. Quality of life of this patient cohort was excellent as shown by a Karnofsky score of more than 80% in 96.6% of patients. The high rate of medical complications and especially of malignant tumours in this long-term follow-up study indicate that further optimization and especially minimization of immunosuppressive therapy as well as development of newer therapies in order to prevent recurrent

    Hydrocephalus is a common complication of posterior fossa surgery, but its real incidence after microvascular decompression (MVD) for idiopathic trigeminal neuralgia (TN) still remains unclear. The aim of this study was to focus on the potential association between MVD and hydrocephalus as a surgery-related complication. All patients who underwent MVD procedure for idiopathic TN at our institute between 2009 and 2014 were reviewed to search for early or late postoperative hydrocephalus. There were 259 consecutive patients affected by idiopathic TN who underwent MVD procedure at our institution between 2009 and 2014 (113 men, 146 women; mean age 59 years, range 30-87 years; mean follow-up 40.92 months, range 8-48 months). Nine patients (3.47 %) developed communicating hydrocephalus after hospital discharge and underwent standard ventriculo-peritoneal shunt. No cases of acute hydrocephalus were noticed. Our study suggests that late communicating hydrocephalus may be an underrated potential long-term complication of MVD surgery.

    While normal exercise myocardial perfusion imaging (SPECT-MPI) is a robust predictor of low short-term clinical risk, there is increasing interest in ascertaining how clinical factors influence long-term risk following SPECT-MPI. We evaluated the predictors of outcome from clinical data obtained at the time of testing in 12,232 patients with normal exercise SPECT-MPI studies. All-cause mortality (ACM) was assessed at a mean of 11.2 ± 4.5 years using the Social Security Death Index. The ACM rate was 0.8%/year, but varied markedly according to the presence of CAD risk factors. Hypertension, smoking, diabetes, exercise capacity, dyspnea, obesity, higher resting heart rate, an abnormal ECG, LVH, atrial fibrillation, and LVEF < 45% were all predictors of increased mortality. Risk factors were synergistic in predicting mortality: annualized age and gender-adjusted ACM rates ranged from only 0.2%/year among patients exercising for >9 minutes having none of three significant risk factors (among hypertension, diabetes, and smoking) to 1.6%/year among patients exercising <6 minutes and having ≥ 2 of these three risk factors. The age and gender-adjusted hazard ratio for mortality was increased by 7.3 (95% confidence interval 5.5-9.7) in the latter patients compared to those patients who exercised >9 minutes and had no significant risk factors (P < .001). Long-term mortality risk varies markedly in accordance with baseline CAD risk factors and functional capacity among patients with normal exercise SPECT-MPI studies. Further study is indicated to determine whether the prospective characterization of both short-term and long-term risks following the performance of stress SPECT-MPI leads to improved clinical management.

    The primary purpose of this article is to provide a broad overview of the research on the long-term effects of childhood risk factors on cardiovascular diseases (CVDs) during adulthood and to outline recommendations for prevention of CVDs based on evidence-based interventions (EBIs). CVDs are the leading cause of death and a major cause of disability in the United States and globally. Risk factors for CVDs are already identifiable in children and youth, and include both modifiable factors (e.g., unhealthy diet, physical inactivity, tobacco smoking), and factors that cannot be changed (e.g., age, heredity, sex). A fundamental issue has been the severity of the long-term effects of childhood risk factors (i.e., behavioral and intermediate risk factors) on subsequent cardiovascular health. It is clear from the empirical evidence that risk factors for CVDs can develop during childhood and adolescence. These risk factors in childhood have been linked to adverse health outcomes, including CVDs, during adulthood. The findings thus far suggest that, in order to be effective and reduce the risk of adulthood CVDs, intervention strategies should begin during childhood. The findings also underscore the importance of adopting a healthy lifestyle as early in life as possible.

    In this study we demonstrated that caries prevalence and Plaque Index in long-term event-free pediatric oncology patients are related to Streptococcus mutans, Lactobacillus counts and buffer capacity obtained by chairside saliva tests. The scores showed a significant correlation between the microbiological findings and caries experience in both groups. The results were compared with a control group. A similarity in the results was found between the study and control groups. In a subgroup consisting of children who were diagnosed with cancer maximum two years before oral examinations, no significant differences with a control group was noticed. In this study we did not find any evidence of long-term effects on the studied salivary caries risk factors in children who are long-term event-free after cytotoxic treatment. Chairside tests seem to be useful in this patient group: they provide us information which can contribute to the determination of the individual caries risk, and help to motivate the patient and health care workers to maintain optimal oral hygiene.

    To identify factors that affect operative mortality and morbidity and long-term survival after completion pneumonectomy. We retrospectively reviewed the charts of consecutive patients who underwent completion pneumonectomy at our cardiothoracic surgery department from January 1996 to December 2005. We identified 69 patients, who accounted for 17.8% of all pneumonectomies during the study period; 22 had benign disease and 47 malignant disease (second primary lung cancer, n=19; local recurrence, n=17; or metastasis, n=11). There were 50 males and 19 females with a mean age of 60 years (range, 29-80 years). Postoperative mortality was 12% and postoperative morbidity 41%. Factors associated with postoperative mortality included obesity (p=0.005), coronary artery disease (p=0.03), removal of the right lung (p=0.02), advanced age (p=0.02), and renal failure (p<0.0001). Preoperative renal failure was the only significant risk factor for mortality by multivariate analysis (p=0.036). Bronchopleural fistula developed in seven patients (10%), with risk factors being removal of the right lung (p=0.04) and mechanical stump closure (p=0.03). Overall survival was 65% after 3 years and 46% after 5 years. Long-term survival was not affected by the reason for completion pneumonectomy. Although long-term survival was acceptable, postoperative mortality and morbidity rates remained high, confirming the reputation of completion pneumonectomy as a challenging procedure. Significant comorbidities and removal of the right lung were the main risk factors for postoperative mortality. Improved patient selection and better management of preoperative renal failure may improve the postoperative outcomes of this procedure, which offers a chance for prolonged survival.

    This study investigated factors associated with long-term use of benzodiazepines (BZDs) or benzodiazepine receptor agonists (BzRAs) as hypnotics in patients with chronic insomnia. Consecutive patients (n = 140) with chronic insomnia were enrolled in this study (68 men and 72 women; mean age, 53.8±10.8 years). All patients filled out a self-assessment questionnaire asking clinical descriptive variables at the baseline of the treatment period; patients received the usual dose of a single type of BZD or BzRA. The Pittsburgh Sleep Quality Index (PSQI) and the Zung Self-Rating Depression Scale were self-assessed at the baseline, and the former was re-evaluated at the time of cessation of medication or at the end of the 6-month treatment period. The PSQI included the following sub-items: evaluating sleep quality (C1), sleep latency (C2), sleep duration (C3), habitual sleep efficiency (C4), frequency of sleep disturbance (C5), use of sleeping medication (C6), and daytime dysfunction (C7). Among the patients, 54.6% needed to continue hypnotics for a 6-month treatment period. Logistic regression analysis revealed that, among descriptive variables, only the PSQI score appeared as a significant factor associated with long-term use {odds ratio (OR) = 2.8, 95% confidence interval (CI) = 2.0–4.0}. The receiver operating curve (ROC) analysis identified that the cut-off PSQI total score at the baseline for predicting long-term use was estimated at 13.5 points (area under the curve = 0.86, 95% CI = 0.8–0.92). Among the sub-items of PSQI, the increases in C1: (OR = 8.4, 95% CI = 2.4–30.0), C3: (OR = 3.6, 95% CI = 1.1–11.5), C4: (OR = 11.1, 95% CI = 3.6–33.9), and C6: (OR = 3.4, 95% CI = 1.9–6.2) scores were associated with long-term use. This study revealed that a high PSQI score at the baseline, particularly in the sub-items relating to sleep maintenance disturbance, is predictive of long-term hypnotic treatment. Our

    Bicuspid aortic valves are associated with valve dysfunction, ascending aortic aneurysm and dissection. Management of the ascending aorta at the time of aortic valve replacement (AVR) in these patients is controversial and has been extrapolated from experience with Marfan syndrome, despite the absence of comparative long-term outcome data. This study sought to assess whether the natural history of thoracic aortopathy after AVR in patients with bicuspid aortic valve disease is substantially different from that seen in patients with Marfan syndrome. In this retrospective comparison, outcomes of 13,205 adults (2,079 with bicuspid aortic valves, 73 with Marfan syndrome, and 11,053 control patients with acquired aortic valve disease) who underwent primary AVR without replacement of the ascending aorta in New York State between 1995 and 2010 were compared. The median follow-up time was 6.6 years. The long-term incidence of thoracic aortic dissection was significantly higher in patients with Marfan syndrome (5.5 ± 2.7%) compared with those with bicuspid valves (0.55 ± 0.21%) and control group patients (0.41 ± 0.08%, p < 0.001). Thoracic aortic aneurysms were significantly more likely to be diagnosed in late follow-up in patients with Marfan syndrome (10.8 ± 4.4%) compared with those with bicuspid valves (4.8 ± 0.8%) and control group patients (1.4 ± 0.2%) (p < 0.001). Patients with Marfan syndrome were significantly more likely to undergo thoracic aortic surgery in late follow-up (10.4 ± 4.3%) compared with those with bicuspid valves (2.5 ± 0.6%) and control group patients (0.50 ± 0.09%) (p < 0.001). The much higher long-term rates of aortic complications after AVR observed in patients with Marfan syndrome compared with those with bicuspid aortic valves confirm that operative management of patients with bicuspid aortic valves should not be extrapolated from Marfan syndrome and support discrete treatment algorithms for these different clinical entities

    Sulfur mustard (SM) is a blistering chemical agent which has short and long term toxicity against many organs. The respiratory tract is one of the main targets, and is the most disabling long term complication of SM. Inflammatory mediators especially IL-8 and IL-6 play the primary role in the various chronic pulmonary diseases. Sardasht-Iran Cohort Study (SICS) was designed to evaluate immunological and molecular parameters in SM exposed people 20 years after exposure. In the present study, the association of the serum levels of IL-8, IL-6, C reactive protein (CRP) and rheumatoid factor (RF) with long term pulmonary involvement was evaluated. There were 348 exposed and 120 control participants. The clinical evaluations were done for all subjects and Spirometry was performed according to American Thoracic Society Criteria. Severity of pulmonary involvement was assessed by Global Initiative for chronic Obstructive Lung Disease (GOLD) classification. The serum levels of IL-8, IL-6 and RF were assessed by ELISA assay. CRP was assessed by photometric method. The serum levels of IL-8 and IL-6 significantly decreased in the SM exposed participants compared to the control group. There were no significant associations between the serum levels of IL-8 and pulmonary symptoms (chronic cough, sputum, hemoptysis, and dyspnea), pulmonary findings (crackles, rales, and wheezing) as well as spirometry parameters. IL-6 was associated with wheezing and CRP was associated with wheezing and rales in SM exposed group. We concluded the serum levels of these inflammatory mediators probably do not have any major role in pathogenesis and persistence of pulmonary complications and do not reflect the degree of severity of pulmonary involvement following SM exposure.

    The main aim of our study was to retrospectively evaluate long-term complications and measure urinary galactose and galactitol excretion in classical galactosemia patients in Estonia who have been treated with a less restricted lactose-free diet and metabolic control. Our study group consisted of five classical galactosemia patients aged 7-14 years and diagnosed since 1996 in Estonia. Their diet eliminates lactose present in dairy foods, but we did not restrict the consumption of mature cheeses, fruits and vegetables. All patients had normal growth, except for one patient who was overweight at the last evaluation. In three patients mental and speech development was normal. One patient, number 1, who was diagnosed latest (at 6 weeks of age), had moderate mental retardation, verbal dyspraxia, extrapyramidal signs and bilateral cataracts. In both patients with developmental problems, a brain MRI showed bilateral subcortical changes in the cerebral white matter. Of four females, only patient 4 (p.Q188R homozygote) has premature ovarian insufficiency. Urinary galactose and galactitol content were retrospectively measured using high-performance liquid chromatography and refractive-index detection from urinary samples that were preserved during the years 1996-2009. Galactose ranged from 60 to 600 mmol/mol creatinine (normal=4-6), and galactitol ranged from 70 to 1200 mmol/mol creatinine (normal=2-4), which was 10-100 and 17-300 times higher than the respective reference ranges for galactose and galactitol. We conclude that a less strict lactose-free diet and metabolic control performed in Estonian classical galactosemia patients does not change long-term outcome compared to previously published studies.

    "Regular visiting/on-demand response type long-term care" has recently been established. This will lead to a decrease in the burden on the family, but an increase in the burden of the care personnel who provide this kind of long-term care. The objectives of this study were to clarify the fatigue symptoms of long-term care workers in facilities that provide this kind of long-term care, and examine the related factors in the workplace. An anonymous questionnaire survey was conducted with 96 workers engaged in long-term care in facilities. The questionnaire was composed of cumulative fatigue symptoms index, work situation, supports in the workplace, and the attributes. The subjects were divided into two groups: those who had night shift between PM 6 to AM 8 with or without day shift (night shift group), and those who had only day shift (day shift group). The relationships between the fatigue symptom levels and work situation etc. were compared between the two groups. The night shift group consisted of 47 workers, whose mean age was 42.3 years and whose mean working experience was 6.0 years. The median number of persons they had visited in the previous month was 9. The day shift group consisted of 49 workers, whose mean age was 44.6 years and whose mean working experience was 5.9 years. The median number of persons they visited in the previous month was 9.5. Age and sex distributions showed no difference between the two groups. There was no difference in the work situations and the supports in the workplace, except for working time and the details of care the subjects were providing. The fatigue symptom levels were high in both groups, but in the night shift group the level of physical disorders was higher than in the day shift group. Satisfaction with work, education and training for mental health and consideration for traffic safety when making home visits were negatively related to fatigue symptom levels in both groups.

    Gestational diabetes mellitus (GDM) was found to be an independent risk factor for recurrent long-term type 2 diabetes mellitus, cardiovascular morbidity, and vascular endothelial dysfunction. However, data on the link between GDM and future risk for long-term maternal renal disease are limited. The purpose of this study was to investigate whether GDM poses a risk for subsequent long-term maternal renal morbidity. A population-based noninterventional study compared the incidence of future renal morbidity in a cohort of women with and without previous GDM. Deliveries occurred during a 25-year period, with a mean follow-up duration of 11.2 years. The study was conducted at the Soroka University Medical Center. The study population was composed of all singleton pregnancies in women who delivered between January 1988 and December 2013. The main outcome was diagnosis of renal morbidities. Of 97,968 women who met the inclusion criteria, 9542 (9.7%) had at least 1 previous pregnancy with GDM. Using a Kaplan-Meier survival curve, we show that women with GDM had higher rates of total renal morbidity (0.1% vs 0.2%, for no GDM and with GDM, respectively; odds ratio, 2.3, 95% confidence interval, 1.4-3.7; P < .001). In addition, we found a significant dose-response association (using the χ(2) test for trends) between the number of pregnancies with GDM and future risk for renal morbidity (0.1%, 0.2%, and 0.4% for no GDM, 1 episode of GDM, and 2 episodes of GDM, respectively; P < .001). In a Cox proportional hazards model, adjusted for confounders, GDM was independently associated with future renal morbidity. GDM is a significant risk factor for future maternal renal morbidity. The risk is more substantial for patients with recurrent episodes of GDM.

    This study investigates the long term economic impact of severe obstetric complications for women and their children in Burkina Faso, focusing on measures of food security, expenditures and related quality of life measures. It uses a hospital based cohort, first visited in 2004/2005 and followed up four years later. This cohort of 1014 women consisted of two main groups of comparison: 677 women who had an uncomplicated delivery and 337 women who experienced a severe obstetric complication which would have almost certainly caused death had they not received hospital care (labelled a “near miss” event). To analyze the impact of such near miss events as well as the possible interaction with the pregnancy outcome, we compared household and individual level indicators between women without a near miss event and women with a near miss event who either had a live birth, a perinatal death or an early pregnancy loss. We used propensity score matching to remove initial selection bias. Although we found limited effects for the whole group of near miss women, the results indicated negative impacts: a) for near miss women with a live birth, on child development and education, on relatively expensive food consumption and on women’s quality of life; b) for near miss women with perinatal death, on relatively expensive foods consumption and children’s education and c) for near miss women who had an early pregnancy loss, on overall food security. Our results showed that severe obstetric complications have long lasting consequences for different groups of women and their children and highlighted the need for carefully targeted interventions.

    To describe a modified implantation procedure of a vagus nerve stimulation (VNS) device in dogs and to report short- and long-term complications. Descriptive, experimental study. Healthy, adult Beagle dogs (n = 10). A VNS Therapy(®) System was implanted in the left cervical region of anesthetized dogs. During and within 48 hours after surgery, electrocardiography (ECG) and impedance testing of the system were performed. Dogs were monitored daily and the impedance of the system was determined regularly until VNS devices were surgically removed 3 years after implantation. The implantation procedure was successful in all dogs without intraoperative complications. ECG monitoring and impedance tests were within normal limits during and within 48 hours after surgery. Postoperative seroma formation was common (70%). One dog developed an irreversible Horner's syndrome leading to removal of the device 5 months after implantation. Another dog developed trauma-induced damage of the lead requiring surgical revision. The device could be safely removed in all dogs; however, electrodes were left in place to avoid nerve damage. At removal, the anchor tether was dislodged in 40% of dogs and the lead was twisted in 50% of dogs. Implantation of a VNS Therapy(®) System is safe and feasible in dogs; however, seroma formation, twisting of the lead, and dislodgement of the anchor tether were common. Practical improvements in the technique include stable device placement, use of a compression bandage, and exercise restriction. Regular evaluation of lead impedance is important, as altered values can indicate serious complications. © Copyright 2015 by The American College of Veterinary Surgeons.

    Extralevator abdominoperineal resection (APR) for low rectal cancer has been adopted by centers to improve oncological outcome. The present study aimed to investigate oncological results, wound complications, and quality of life (QoL). Patients who underwent extralevator APR for rectal cancer between 2007 and 2011 were identified retrospectively. QoL status was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CR30 and CR29 questionnaires. Thirty laparoscopic (n = 7) or open (n = 23) extralevator APRs were performed in 17 male and 13 female patients. The mortality was zero; circumferential margin involvement occurred in two cases (6.7 %); and there was no bowel perforation. No local recurrence was noted after a median follow-up of 28.3 months; however, six patients died, and eight developed distant metastases. Perineal wound complications were found in 46.6 % of patients, and all were managed conservatively. Fifty percent of the patients reported persistent perineal pain at the follow-up exam. QoL was assessed 7 to 46 months after surgery, and the global health status (70.6) was comparable to the EORTC reference group and published conventional APR series. The QLQ-CR29 module revealed high mean symptom scores for urinary frequency (48.1), incontinence (30.5), and impotence (79.1). Extralevator APR can control local recurrence but not distant metastases of low rectal cancer. The extended perineal resection appears not to decrease general QoL, but it results in a high rate of perineal wound complications. Genitourinary functions are often impaired, even in the long term, and further improvements to the technique must seek to reduce genitourinary harm.

    The Idaho National Laboratory (INL) is a multipurpose national laboratory delivering specialized science and engineering solutions for the U.S. Department of Energy (DOE). Sponsorship of INL was formally transferred to the DOE Office of Nuclear Energy, Science and Technology (NE) by Secretary Spencer Abraham in July 2002. The move to NE, and designation as the DOE lead nuclear energy laboratory for reactor technology, supports the nation’s expanding nuclear energy initiatives, placing INL at the center of work to develop advanced Generation IV nuclear energy systems; nuclear energy/hydrogen coproduction technology; advanced nuclear energy fuel cycle technologies; and providing national security answers to national infrastructure needs. As a result of the Laboratory’s NE mission, INL generates both contact-handled and remote-handled transuranic (TRU) waste from ongoing operations. Generation rates are relatively small and fluctuate based on specific programs and project activities being conducted; however, the Laboratory will continue to generate TRU waste well into the future in association with the NE mission. Currently, plans and capabilities are being established to transfer INL’s contact-handled TRU waste to the Advanced Mixed Waste Treatment Plant (AMWTP) for certification and disposal to the Waste Isolation Pilot Plant (WIPP). Remote-handled TRU waste is currently placed in storage at the Materials and Fuels Complex (MFC). In an effort to minimize future liabilities associated with the INL NE mission, INL is evaluating and assessing options for the management and disposition of all its TRU waste on a real-time basis at time of generation. This paper summarizes near-term activities to minimize future re handling of INL’s TRU waste, as well as, potential complications associated with the long-term disposition of newly-generated TRU waste. Potential complications impacting the disposition of INL newly-generated TRU waste include, but are not limited to

    The management of acute type A aortic dissection complicated by coma remains controversial. We previously reported an excellent rate of recovery of consciousness provided aortic repair was performed within 5 hours of the onset of symptoms. This study evaluates the early and long-term outcomes using this approach. Between August 2003 and July 2013, of the 241 patients with acute type A aortic dissection brought to the Japanese Red Cross Kobe Hospital and Hyogo Emergency Medical Center, 30 (12.4%) presented with coma; Glasgow Coma Scale was less than 11 on arrival. Surgery was performed in 186 patients, including 27 (14.5%) who were comatose. Twenty-four comatose patients underwent successful aortic repair immediately (immediate group). Their mean age was 71.0 ± 11.1 years, Glasgow Coma Scale was 6.5 ± 2.4, and prevalence of carotid dissection was 79%. For brain protection, deep hypothermia with antegrade cerebral perfusion was used, and postoperative induced hypothermia was performed. Neurologic evaluations were performed using the Glasgow Coma Scale, National Institutes of Health Stroke Scale, and modified Rankin Scale. In the immediate group, the time from the onset of symptoms to arrival in the operating theater was 222 ± 86 minutes. Hospital mortality was 12.5%. Full recovery of consciousness was achieved in 79% of patients in up to 30 days. Postoperative Glasgow Coma Scale and National Institutes of Health Stroke Scale improved significantly when compared with the preoperative score (P < .05), and postoperative activities of daily living independence (modified Rankin Scale <3) was achieved in 50% of patients. The mean follow-up period was 56.5 months, and the cumulative survival was 48.2% after 10 years. Cox proportional hazards regression analysis indicated that immediate repair (hazard ratio, 4.3; P = .007) was the only significant predictor of postoperative survival over a 5-year period. The early and long-term outcomes as a result of immediate aortic

    The application of mesh-reinforced hiatal closure has resulted in a significant reduction in recurrence rates in comparison with primary suture repair. However, the use of meshes has not completely extended in all the cases of large paraesophageal hiatal hernias (LPHH) due to the complications related to them. The aim of this study is to present our long-term results and complications related to Crurasoft(®) mesh (Bard) for the treatment of LPHH. From January 2004 to December 2014, 536 consecutive patients underwent open or laparoscopic fundoplication for gastroesophageal reflux disease or LPHH at Ramón y Cajal University Hospital. Primary simple suture of the crura and additional reinforcement with a Crurasoft(®) mesh (Bard) was performed in 93 patients (17.35 %). Radiologic hiatal hernia recurrence and mesh-related complications were investigated. Of the 93 patients undergoing mesh repair, there were 28 male and 65 female with a mean age of 67.27 years (range 22-87 years). Laparoscopic surgery was attended in 88.2 % of the cases, and open surgery in the rest 11.8 %. Mean operative time was 167.05 min (range 90-370 min). Median postoperative stay was 4.79 days (range 1-41 days). Conversion rate was 8.53 % (7 patients). Intraoperative complications were described in 10.75 % (10 patients), but all of them, except in one case, could be managed laparoscopically. Overall postoperative complications rate was 28 %. Early postoperative complications occurred in 11 patients (12 %), respectively, for grades 2 (6 cases), 3b (1 case) and 5 (4 cases) according to the Clavien-Dindo classification. Late postoperative complications occurred in 15 patients (16 %), respectively, for grades 1 (7 cases), 2 (2 cases), 3b (5 cases) and 5 (1 case) according to the Clavien-Dindo classification. Thirty day-mortality rate was 4.3 %. Mortality rate specific associated with the mesh was 1 %. Reoperation rate was 5.4 %. After a median follow-up of 76.33 months (range 3

    Allocation of manual versus automated tasks for operation and maintenance of nuclear power systems in space will be crucial at the onset and at the return of a space flight. Such factors as space adaptation syndrome (SAS), a temporary space motion sickness that has affected 40 to 50% of crew members on past space flights, can result in lost effort ranging from a few hours to a full day. This could have a significant impact on manual performance where high levels of execution are likely to be required in the very early stages of the mission. Other considerations involving higher-level behavioral phenomena such as interpersonal and group processes, individual belief systems, social and motivational factors, and (subjective) cognitive function have received little attention; nevertheless these will be essential elements for success in long-term exploration. Understanding that long-term space flight missions may create groups that become unique societies distinct unto themselves will test current ethical, moral, and social belief systems, requiring one to examine the amalgamation as well as organizational structures for the safety and balance of the crew.

    To assess the effects of socioeconomic factors on the association between parity and long-term maternal mortality. This was a population-based cohort study of mothers with births registered in the Medical Birth Registry of Norway during the period 1967-2009. We estimated age-specific (40-69 years) cardiovascular and noncardiovascular mortality ratios by number of births using Cox proportional hazard models. To assess effect modification by mothers' attained education, we stratified on low (less than 11 years) and high (11 years or greater) educational level. We further evaluated fathers' mortality by number of births using the same analytical approach. Mothers with low education had higher mortality (cardiovascular: hazard ratio 2.62, 95% confidence interval [CI] 2.34-2.93, noncardiovascular: hazard ratio 1.67, 95% CI 1.62-1.73). Among mothers with low education, cardiovascular mortality increased linearly with each additional birth above one (P trend=.02). In contrast, among mothers with high education, cardiovascular mortality declined with added births (P trend=.045). For noncardiovascular mortality there was no association among mothers with low education, whereas mortality declined with increasing number of births among mothers with high education (P trend<.01). Father's mortality showed similar associations with number of births when stratified on maternal education. Women's long-term mortality rose with number of births only for cardiovascular causes of death and only among mothers with low education. Partners of women with low education had similar increasing risk with increasing number of births. Maternal educational level is a strong modifier of the association between parity and long-term mortality. II.

    Long-term care (LTC) is an important sector of the health care industry. However, the adoption of health information technology (HIT) systems in LTC facilities lags behind that in other sectors of health care. Previous literature has focused on the financial and technical barriers. This study examined the organizational factors associated with HIT adoption in LTC facilities. A survey of 500 LTC facilities in Texas enabled researchers to compile HIT indexes for further statistical analyses. A general linear model was used to study the associations between the clinical/administrative HIT indexes and organizational factors. The empirical outcomes show that the size of an LTC facility has a significant association with HIT adoption. Rural LTC facilities, especially freestanding ones, adopt less HIT than their urban counterparts, whereas freestanding LTC facilities have the lowest HIT adoption overall. There is not enough evidence to support ownership status as a significant factor in HIT adoption. Some implications are proposed, but further research is necessary.

    AIM To identify predictive factors associated with long-term patient and graft survival (> 15 years) in liver transplant recipients. METHODS Medical charts of all de novo adult liver transplant recipients (n = 140) who were transplanted in Hamburg between 1997 and 1999 were retrospectively reviewed. In total, 155 transplantations were identified in this time period (15 re-transplantations). Twenty-six orthotopic liver transplant (OLT) recipients were early lost to follow-up due to moving to other places within 1 year after transplantation. All remaining 114 patients were included in the analysis. The following recipient factors were analysed: Age, sex, underlying liver disease, pre-OLT body mass index (BMI), and levels of alanine aminotransferase (ALT), bilirubin, creatinine and gamma-glutamyltransferase (gamma-GT), as well as warm and cold ischemia times. Furthermore, the following donor factors were assessed: Age, BMI, cold ischemia time and warm ischemia time. All surviving patients were followed until December 2014. We divided patients into groups according to their underlying diagnosis: (1) hepatocellular carcinoma (n = 5, 4%); (2) alcohol toxic liver disease (n = 25, 22.0%); (3) primary sclerosing cholangitis (n = 6, 5%); (4) autoimmune liver diseases (n = 7, 6%); (5) hepatitis C virus cirrhosis (n = 15, 13%); (6) hepatitis B virus cirrhosis (n = 21, 19%); and (7) other (n = 35, 31%). The group “other” included rare diagnoses, such as acute liver failure, unknown liver failure, stenosis and thrombosis of the arteria hepatica, polycystic liver disease, Morbus Osler and Caroli disease. RESULTS The majority of patients were male (n = 70, 61%). Age and BMI at the time point of transplantation ranged from 16 years to 69 years (median: 53 years) and from 15 kg/m2 to 33 kg/m2 (median: 24), respectively. Sixty-six OLT recipients (58%) experienced a follow-up of 15 years after transplantation. Recipient’s age (P = 0.009) and BMI (P = 0.029) were identified as

    Thirty-one patients treated with mesenchymal stromal cells (MSCs) for acute graft-versus-host disease (aGVHD) or hemorrhagic cystitis between 2002 and 2007 were followed to investigate predictors of outcome, immunologic effects in vivo, and long-term survival. There was no correlation between in vitro suppression by MSCs in mixed lymphocyte cultures and outcome. Soluble IL-2 receptors were measured in blood before and after MSC infusion and declined significantly during the first week after MSC infusion (P = .03). Levels of interleukin-6 and HLA-G were unaffected. Infectious complications occurred several years after recovery from aGVHD. Cytomegalovirus viral load was high, and cytomegalovirus disease was common. Among patients recovering from aGVHD, 54% died of late infections, between 4 months and 2 years after MSC treatment. No increase in leukemia relapse or graft rejection was found. Children had a better survival rate than adults (P = .005). In GVHD patients, 1-year survival was 75% in patients who received early-passage MSCs (from passages 1-2) in contrast to 21% using later passage MSCs (from passages 3-4) (P < .01). We conclude that treatment with early-passage MSCs improved survival in patients with therapy-resistant GVHD. Death from infection was common in MSC-treated patients, but there was no increase in leukemia relapse. Copyright © 2012 American Society for Blood and Marrow Transplantation.

    Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus neoformans and most remarkably manifests in HIV-infected individuals, especially in the settings of very low CD4 count. Development of cryptococcosis in HIV-uninfected individuals is exceedingly rare and usually signifies a marked immunodeficiency. Cryptococcosis in association with myasthenia gravis or thymoma has been previously documented in only very few cases in the literature. We reported a complicated case of severe cutaneous cryptococcosis in a 39-year-old Vietnamese male patient with myasthenia gravis on long-term immunosuppressive therapy. The patient presented with a five month history of recurrent and progressive skin lesions that later on progressed into cryptococcal meningitis. Through this case, we aimed to emphasize the importance of including cutaneous cryptococcosis in the differential diagnosis of cutaneous lesions in patients on chronic immunosuppressive therapy. The cutaneous manifestations of cryptococcosis can be the first clue for a disseminated disease, which makes early recognition crucial and life-saving.

    Background: Despite almost the three decades passed since the chemical attacks of Iraqi's army against the Iranian troops, some veterans are still suffering from long-term complications of sulfur mustard (SM) poisoning, including certain skin complaints specially dryness, burning, and pruritus. We thus aimed to evaluate the skin's water and lipid content in patients with a disability of >25% due to complications of SM poisoning and compare them with a matched control group. Materials and Methods: Sixty-nine male participants were included in this study; 43 SM-exposed patients, and 26 normal controls from their close relatives. The water and lipid content was measured in four different locations: Extensor and flexor sides of forearms and lateral and medial sides of legs by the Corneometer CM 820/Sebumeter SM 810. Collected data was analyzed and P ≤ 0.05 was considered as statistically significant. Results: The mean age of the patients and controls was 49.53 ± 11.34 (ranges: 40-71) and 29.08 ± 8.836 (ranges: 15-49 years), respectively. In the veterans group, the main cutaneous complaint was itching and skin dryness. Cherry angioma, dry skin, and pruritus were significantly more common in the SM-exposed cases than in the controls. (P = 0.01, 0.05, and 0.04, respectively). The moisture and lipid content of all areas were lower in the SM-exposed group, but it was only significant in skin sebum of lateral sides of legs (P = 0.02). Conclusion: Exposure to SM could decrease the function of stratum corneum and lipid production as a barrier, even after several years of its exposure. PMID:26622252

    There is little information on the effect of acute coronary syndrome complicated by ventricular fibrillation on the long-term incidence of sudden cardiac death. We analyzed this effect in a contemporary cohort of patients with acute coronary syndrome. We studied 5302 consecutive patients with acute coronary syndrome between December 2003 and December 2012. We compared mortality during and after hospitalization according to the presence or absence of ventricular fibrillation. Ventricular fibrillation was observed in 163 (3.1%) patients, and was early onset in 72.4% of these patients. In-hospital mortality was 36.2% in the group with ventricular fibrillation and 4.7% in the group without (p<.001). After a mean follow-up of 4.7 years (standard deviation, 2.6 years), mortality was 30.7% in the ventricular fibrillation group and 24.7% in the other group (P=.23). After adjusting for confounding variables, the presence of ventricular fibrillation was not associated with an increased risk of death in the follow-up period (hazard ratio=1.29; 95% confidence interval, 0.90-1.87). The cause of death was established in 72% of patients. The incidence of sudden death was 12.9% in the ventricular fibrillation group and 11.9% in the other group (P=.71). Cardiovascular-cause mortality was also similar between the 2 groups (35.5% and 34.4%, respectively. Patients with acute coronary syndrome complicated by ventricular fibrillation who survive the in-hospital phase do not appear to be at an increased risk of sudden cardiac death or other cardiovascular-cause death.

    Purpose: Intensification of radiotherapy and chemotherapy for head-and-neck cancer may lead to increased rates of dysphagia. Dosimetric predictors of objective findings of long-term dysphagia were sought. Methods and Materials: From an institutional database, 83 patients were identified who underwent definitive intensity-modulated radiotherapy for squamous cell carcinoma of the head and neck, after exclusion of those who were treated for a second or recurrent head-and-neck primary lesion, had locoregional recurrence at any time, had less than 12 months of follow-up, or had postoperative radiotherapy. Dosimetric parameters were analyzed relative to three objective endpoints as a surrogate for severe long-term dysphagia: percutaneous endoscopic gastrostomy (PEG) tube dependence at 12 months, aspiration on modified barium swallow, or pharyngoesophageal stricture requiring dilation. Results: Mean dose greater than 41 Gy and volume receiving 60 Gy (V{sub 60}) greater than 24% to the larynx were significantly associated with PEG tube dependence and aspiration. V{sub 60} greater than 12% to the inferior pharyngeal constrictor was also significantly associated with increased PEG tube dependence and aspiration. V{sub 65} greater than 33% to the superior pharyngeal constrictor or greater than 75% to the middle pharyngeal constrictor was associated with pharyngoesophageal stricture requiring dilation. Conclusions: Doses to the larynx and pharyngeal constrictors predicted long-term swallowing complications, even when controlled for other clinical factors. The addition of these structures to intensity-modulated radiotherapy optimization may reduce the incidence of dysphagia, although cautious clinical validation is necessary.

    A follow-up study was made on 200 children (115 boys, 85 girls) who had had infantile spasms, in order to compare their present condition over the age of six years with various prognostic factors. 48 of the children (30 males and 18 females) had died, and all the rest were aged six years or older at the time of final follow-up. 139 of the children had received ACTH therapy: at final follow-up, spasms had ceased in 43.5 per cent, and about the same proportion showed normal physical development; 23 per cent had normal mental development and 15.4 per cent were attending ordinary schools. Complete recovery (normal mental and physical development and attending ordinary schools) was achieved in only 19 cases (9.5 per cent). Of the cryptogenic cases, 44.4 per cent had made a full recovery. The poor prognostic factors for continuing seizures were evolution into other types of fits, relapse of seizures after ACTH therapy, seizures concomitant with spasms, and convulsions before the onset of spasms. Poor prognostic factors for physical development were delayed development before the onset of spasms, neurological abnormalities, PEG abnormality, symptomatic aetiology, neonatal convulsions, low birthweight, perinatal asphyxia and being female. Poor prognostic factors for mental development were delayed development before the onset of spasms, neurological abnormalities, PEG abnormality, prenatal and perinatal aetiology, relapse after initial ACTH therapy, laughing attacks, and evolution into other types of fits. Only in the cryptogenic cases was there significant correlation between the delay in treatment and the long-term prognosis for mental development. Poor prognostic factors for educability were very similar to those for mental development. In spite of conflicting views as to the long-term effects of ACTH, prompt treatment seems to be mandatory, at least in cryptogenic cases of infantile spasms.

    It is important for nurses who work in long-term care facilities (LTCFs) to have an adequate level of computer competency due to the multidisciplinary and comprehensive nature of long-term care services. Thus, it is important to understand the current computer competency of nursing staff in LTCFs and the factors that relate to this competency. To explore the computer competency of LTCF nurses and to identify the demographic and computer-usage characteristics that relate significantly to computer competency in the LTCF environment. A cross-sectional research design and a self-report questionnaire were used to collect data from 185 nurses working at LTCFs in Taipei. The results found that the variables of the frequency of computer use (β = .33), age (β = -.30), type(s) of the software used at work (β = .28), hours of on-the-job training (β = -.14), prior work experience at other LTCFs (β = -.14), and Internet use at home (β = .12) explain 58.0% of the variance in the computer competency of participants. The results of the present study suggest that the following measures may help increase the computer competency of LTCF nurses. (1) Nurses should be encouraged to use electronic nursing records rather than handwritten records. (2) On-the-job training programs should emphasize participant competency in the Excel software package in order to maintain efficient and good-quality of LTC services after implementing of the LTC insurance policy.

    In long-term care facilities (LTCF), registered nurses (RNs) perform both clinical and supervisory roles as part of a team aiming to provide high-quality care to residents. The residents have several co-morbidities and complex care needs. Unfortunately, new RNs receive minimal preparation in gerontology and supervisory experience during their program, leading to low retention rates and affecting resident outcomes. This qualitative study explored factors that influence supervisory performance of new RNs in LTCF from the perspective of 24 participants from Ontario, Canada. Data were collected through individual interviews, followed by a directed content analysis. Three levels of influences were identified: personal influences, organizational influences, and external influences. Each level presented with sub-elements, further describing the factors that impact the supervisory performance of the new RN. To retain new RNs in LTC, organizations must provide additional gerontological education and mentoring for new RNs to flourish in their supervisory roles.

    INTRODUCTION In the past few decades, mental health problems have increasingly contributed to sickness absence and long-term disability. However, little is known about prognostic factors of return to work (RTW) and disability of persons already on sick leave due to mental health problems. Understanding these factors may help to develop effective prevention and intervention strategies to shorten the duration of disability and facilitate RTW. METHOD We reviewed systematically current scientific evidence about prognostic factors for mental health related long term disability, RTW and symptom recovery. Searching PubMed, PsycINFO, Embase, Cinahl and Business Source Premier, we selected articles with a publication date from January 1990 to March 2009, describing longitudinal cohort studies with a follow-up period of at least 1 year. Participants were persons on sick leave or receiving disability benefit at baseline. We assessed the methodological quality of included studies using an established criteria list. Consistent findings in at least two high quality studies were defined as strong evidence and positive findings in one high quality study were defined as limited evidence. RESULTS Out of 796 studies, we included seven articles, all of high methodological quality describing a range of prognostic factors, according to the ICF-model categorized as health-related, personal and external factors. We found strong evidence that older age (>50 years) is associated with continuing disability and longer time to RTW. There is limited evidence for the association of other personal factors (gender, education, history of previous sickness absence, negative recovery expectation, socio-economic status), health related (stress-related and shoulder/back pain, depression/anxiety disorder) and external i.e., job-related factors (unemployment, quality and continuity of occupational care, supervisor behavior) with disability and RTW. We found limited evidence for the association of

    Background Unemployment is associated with reduced physical and psychological well-being. Perceived health is an important factor influencing health outcomes as well as successful returns to work. This study aims to determine the extent to which perceived health correlates with mental health, various health risk characteristics and socio-demographic characteristics in a setting-selected sample of long-term unemployed persons. Methods Using SF-12, 365 long-term unemployed persons were assessed for self-perceived health and various socio-demographic and health characteristics. Perceived health data of the sample was compared to the German SF-12 reference population. Bivariate analyses and multiple linear regression models were applied to identify those variables significantly associated with perceived health. Results The study population reported poorer perceived health compared with the general population. Analyses showed that perceived mental health was significantly worse in women, among persons with heightened depression and anxiety scores, and in participants reporting reduced levels of physical activity. Perceived physical health was significantly lower among older persons, participants with a higher BMI, and participants with heightened depression and anxiety scores. Both mental and physical health were worse among the unemployed assigned to an employment center as compared to those engaged in the secondary labor market. In total, 36% of the variance in the SF-12 mental score and 20% of the variance in the SF-12 physical score were explained by the factors included in the final multiple linear regression models. Conclusions Perceived health among a select group of long-term unemployed is reduced to a clinically relevant extent compared to the general population. The preliminary findings underline an association between mental health and perceived health. Negative self-perceptions of health were also associated with the labor market setting and some of the

    Although intracranial Rosai-Dorfman disease is a principally benign lymphohistiocytosis, some patients run a relapsing or progressive course. However, reports about long-term follow-up are extremely rare. In two patients, initial tumor resection was incomplete or followed by recurrences over 3 years, which finally subsided after application of chemotherapy, and patients remained tumor-free for more than 7 years thereafter. Up to now there is no agreement on how to treat complicated cases of intracranial Rosai-Dorfman disease; our good experience with adjuvant chemotherapy and long-term follow-up will contribute to treatment planning in complicated cases.

    Occipital neuralgia is a rare cause of severe headache characterized by paroxysmal shooting or stabbing pain in the distribution of the greater occipital or lesser occipital nerve. In cases of intractable occipital neuralgia, a definite cause has not been uncovered, so various types of treatment have been applied. The aim of this study is to evaluate the prognostic factors, safety, and long-term clinical efficacy of second cervical (C2) ganglion decompression for intractable occipital neuralgia. Retrospective analysis was performed in 68 patients with medically refractory occipital neuralgia who underwent C2 ganglion decompression. Factors based on patients' demography, pre- and postoperative headache severity/characteristics, medication use, and postoperative complications were investigated. Therapeutic success was defined as pain relief by at least 50 % without ongoing medication. The visual analog scale (VAS) score was significantly reduced between the preoperative and most recent follow-up period. One year later, excellent or good results were achieved in 57 patients (83.9 %), but poor in 11 patients (16.1 %). The long-term outcome after 5 years was only slightly less than the 1-year outcome; 47 of the 68 patients (69.1 %) obtained therapeutic success. Longer duration of headache (over 13 years; p = 0.029) and presence of retro-orbital/frontal radiation (p = 0.040) were significantly associated with poor prognosis. In the current study, C2 ganglion decompression provided durable, adequate pain relief with minimal complications in patients suffering from intractable occipital neuralgia. Due to the minimally invasive and nondestructive nature of this surgical procedure, C2 ganglion decompression is recommended as an initial surgical treatment option for intractable occipital neuralgia before attempting occipital nerve stimulation. However, further study is required to manage the pain recurrence associated with longstanding nerve injury.

    Malnutrition is common in the first few months after stroke and contributes to a poor overall outcome. We analyzed long-term weight changes and their predictive factors. A total of 71 first-ever stroke patients were included in the study and examined (1) their weight on admission to the acute stroke unit (usual weight [UW]), on admission to the rehabilitation unit, on discharge from the rehabilitation unit, and then 1 year or more after the stroke (median time: 2.5 years), (2) the presence of malnutrition after stroke, and (3) possible predictive factors, namely, sociodemographic factors, clinical characteristics (concerning the stroke, the patient's current neurologic status and the presence of diabetes mellitus and depression), and the present nutritional state (including eating difficulties, anorexia, and changes in food intake and food preferences). Body weight fell (4.0 kg) during the patients' stay in the stroke unit, increased moderately in the rehabilitation unit (2.0 kg), and returned to the UW by the long-term measurement. However, at the last observation, 40.1% of the patients weighed markedly less than their UW, 38.0% weighed markedly more, and 21.1% were relatively stable. Predictors of weight change were a change in preferences for sweet food products and a change in food intake. Malnutrition was frequent (47.9%) and associated with reduced food intake, residence in an institution, and diabetes mellitus. Malnutrition was highly prevalent, with an important role of change in food intake and food preferences, which could result from brain lesions and specific regimens. Living in an institution needs consideration, as its negative effects can be prevented. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    The objective of the study was to investigate the prevalence of, and factors associated with, polypharmacy in long-term care facilities (LTCFs). MEDLINE, EMBASE, International Pharmaceutical Abstracts, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library were searched from January 2000 to September 2014. Primary research studies in English were eligible for inclusion if they fulfilled the following criteria: (1) polypharmacy was quantitatively defined, (2) the prevalence of polypharmacy was reported or could be extracted from tables or figures, and (3) the study was conducted in a LTCF. Methodological quality was assessed using an adapted version of the Joanna Briggs Institute Critical Appraisal Checklist. Forty-four studies met the inclusion criteria and were included. Polypharmacy was most often defined as 5 or more (n = 11 studies), 9 (n = 13), or 10 (n = 11) medications. Prevalence varied widely between studies, with up to 91%, 74%, and 65% of residents taking more than 5, 9, and 10 medications, respectively. Seven studies performed multivariate analyses for factors associated with polypharmacy. Positive associations were found for recent hospital discharge (n = 2 studies), number of prescribers (n = 2), and comorbidity including circulatory diseases (n = 3), endocrine and metabolic disorders (n = 3), and neurological motor dysfunctioning (n = 3). Older age (n = 5), cognitive impairment (n = 3), disability in activities of daily living (n = 3), and length of stay in the LTCF (n = 3) were inversely associated with polypharmacy. The prevalence of polypharmacy in LTCFs is high, varying widely between facilities, geographical locations and the definitions used. Greater use of multivariate analysis to investigate factors associated with polypharmacy across a range of settings is required. Longitudinal research is needed to explore how polypharmacy has evolved over time. Copyright © 2015 AMDA – The Society for Post-Acute and Long-Term

    Application of endosseous implants in prosthetic orbital reconstruction seems to be very successful, but few reports have evaluated cumulative survival rates of orbital implants over a long period. The aim of this study was to analyze long-term survival rates and potential influencing factors of orbital implants. A retrospective evaluation of patients treated with extraoral screw implants for retaining orbital prostheses from 1991 to 2014 was performed. Patient records were assessed for implant survival, demographic data, defect etiology, irradiation status, location of implant placement, implant systems, length, and retention type. Data were analyzed using the Kaplan-Meier method and log-rank test to compare survival curves. A total of 282 orbital implants placed in 78 patients were evaluated during an observation period ranging from 2 to 268 months (mean: 94.97 months). The cumulative implant survival rate was 91.3% at 2 years, 80.5% at 5 years, 68.7% at 10 years, and 62.2% after 15 years. The survival rate was significantly higher in females (75.3%) vs males (47.3%), in supraorbital vs infraorbital implants (67.4% vs 51.5%), and in Brånemark implants (70.2%) vs Straumann implants (54.5%). The presented data suggest that the long-term predictability of orbital implants revealed good to acceptable results. Factors such as female gender, localization in the supraorbital rim, a machined surface of the implant system, length, and magnetic retention seem to affect the implant survival rate positively, whereas irradiation status does not show any influence. These factors should be considered in planning future patient rehabilitation.

    Objective To test whether elevated concentration of rheumatoid factor is associated with long term development of rheumatoid arthritis. Design A prospective cohort study, the Copenhagen City Heart Study. Blood was drawn in 1981-83, and participants were followed until 10 August 2010. Setting Copenhagen general population. Participants 9712 white Danish individuals from the general population aged 20-100 years without rheumatoid arthritis at study entry. Main outcome measures Rheumatoid arthritis according to baseline plasma IgM rheumatoid factor level categories of 25-50, 50.1-100, and >100, versus <25 IU/mL. Results Rheumatoid factor levels were similar from age 20 to 100 years. During 187 659 person years, 183 individuals developed rheumatoid arthritis. In healthy individuals, a doubling in levels of rheumatoid factor was associated with a 3.3-fold (95% confidence interval 2.7 to 4.0) increased risk of developing rheumatoid arthritis, with a similar trend for most other autoimmune rheumatic diseases. The cumulative incidence of rheumatoid arthritis increased with increasing rheumatoid factor category (Ptrend<0.0001). Multivariable adjusted hazard ratios for rheumatoid arthritis were 3.6 (95% confidence interval 1.7 to 7.3) for rheumatoid factor levels of 25-50 IU/mL, 6.0 (3.4 to 10) for 50.1-100 IU/mL, and 26 (15 to 46) for >100 IU/mL, compared with <25 IU/mL (Ptrend<0.0001). The highest absolute 10 year risk of rheumatoid arthritis of 32% was observed in 50-69 years old women who smoked with rheumatoid factor levels >100 IU/mL. Conclusion Individuals in the general population with elevated rheumatoid factor have up to 26-fold greater long term risk of rheumatoid arthritis, and up to 32% 10 year absolute risk of rheumatoid arthritis. These novel findings may lead to revision of guidelines for early referral to a rheumatologist and early arthritis clinics based on rheumatoid factor testing. PMID:22956589

    The Bernese periacetabular osteotomy (PAO) continues to be a commonly performed nonarthroplasty option to treat symptomatic developmental hip dysplasia, but there are few long-term followup studies evaluating results after PAO. (1) What is the long-term survivorship of the hip after PAO? (2) What were the validated outcomes scores among patients who had PAO more than 14 years ago? (3) What factors are associated with long-term failure? One hundred fifty-eight dysplastic hips (133 patients) underwent PAO between May 1991 and September 1998 by a single surgeon. Of those, 37 hips (34 patients [26%]) were lost to followup; an additional seven patients (5% [eight hips]) had not been seen in the last 5 years. The 121 hips (in 99 patients) were retrospectively evaluated at a mean of 18 years (range, 14-22 years). Survivorship was assessed using Kaplan-Meier analysis with total hip arthroplasty (THA) as the endpoint. Hips were evaluated for activity, pain, and general health using the UCLA Activity Score, modified Harris hip score, WOMAC, and Hip disability and Osteoarthritis Outcome Score (HOOS). Failure was defined as a WOMAC pain subscale score ≥ 10 or having undergone THA. Hips were divided into three groups: asymptomatic (did not meet any failure criteria at any point in time), symptomatic (met WOMAC pain failure criteria at previous or most recent followup), and replaced (having undergone THA). A multinomial logistic regression model using a general estimating equations approach was used to assess factors associated with failure. Kaplan-Meier analysis with THA as the endpoint revealed a survival rate (95% confidence interval [CI]) of 74% (66%-83%) at 18 years. Twenty-six hips (21%) underwent THA at an average of 9 ± 5 years from the surgery. Sixty-four hips (53%) remained asymptomatic and did not meet any failure criteria at most recent followup. Thirty-one hips (26%) were symptomatic and considered failed based on a WOMAC pain score of ≥ 10 with a mean ± SD of

    To identify factors affecting periprocedural morbidity and mortality and long-term survival following hepatic artery embolization (HAE) of hepatic neuroendocrine tumor (NET) metastases. This single-center, institutional review board-approved retrospective review included 320 consecutive HAEs for NET metastases performed in 137 patients between September 1996 and September 2007. Forty-seven HAEs (15%) were performed urgently to manage refractory symptoms in inpatients (urgent group), and 273 HAEs (85%) were elective (elective group). Overall survival (OS) was estimated by Kaplan-Meier methodology. Complications were categorized per Common Terminology Criteria for Adverse Events, version 4.0. Univariate and multivariate analyses were performed to determine independent predictors for OS, complications, and 30-day mortality. The independent factors were combined to develop clinical risk score groups. Urgent HAE (P = .007), greater than 50% liver replacement by tumor (P < .0001), and extrahepatic metastasis (P = .007) were independent predictors for shorter OS. Patients with all three risk factors had decreased OS versus those with none (median, 8.5 vs 86 mo; P < .001). Thirty-day mortality was significantly lower in the elective (1%) versus the urgent group (8.5%; P = .0009). There were eight complications (3%) in the elective group and five (10.6%) in the urgent group (P = .03). Male sex and urgent group were independent factors for higher 30-day mortality rate (P = .023 and P =.016, respectively) and complications (P = .012 and P =.001, respectively). Urgent HAE, replacement of more than 50% of liver by tumor, and extrahepatic metastasis are strong independent predictors of shorter OS. Male sex and urgent HAE carry higher 30-day mortality and periprocedural morbidity risks. © 2013 Published by SIR on behalf of The Society of Interventional Radiology.

    Clinical practice guidelines recommend yearly surveillance mammography for breast cancer survivors, yet many women do not receive this service. The objective of this study was to evaluate factors related to long-term surveillance mammography adherence among breast cancer survivors. We conducted a retrospective cohort study among women ≥ 18 years, diagnosed with incident stage I or II breast cancer between 1990 and 2008. We used medical record and administrative health plan data to ascertain covariates and receipt of surveillance mammography for up to 10 years after completing breast cancer treatment. Surveillance included post-diagnosis screening exams among asymptomatic women. We used multivariable repeated measures generalized estimating equation regression models to estimate odds ratios and robust 95 % confidence intervals to examine factors related to the annual receipt of surveillance mammography. The analysis included 3,965 women followed for a median of six surveillance years; 79 % received surveillance mammograms in year 1 but decreased to 63 % in year 10. In multivariable analyses, women, who were < 40 years or 80+ years of age (compared to 50-59 years), current smokers, had greater comorbidity, were diagnosed more recently, had stage II cancer, or were treated with mastectomy or breast conserving surgery without radiation, were less likely than other women to receive surveillance mammography. Women with outpatient visits during the year to primary care providers, oncologists, or both were more likely to undergo surveillance. In this large cohort study of women diagnosed with early-stage invasive breast cancer, we found that important subgroups of women are at high risk for non-adherence to surveillance recommendations, even among younger breast cancer survivors. Efforts should be undertaken to actively engage breast cancer survivors in managing long-term surveillance care.

    The aim of this study was to compare the long-term postoperative status of hypospadiac patients by analysing their sexual psychology, sexual behaviour, sexual function and influencing factors. A total of 130 hypospadiac patients hospitalized between January 1988 and December 2007 were followed up with questionnaires using Zung's Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), a self-designed sexual function questionnaire and a 5-item version of the International Index of Erectile Function (IIEF-5). The surveys served to evaluate the effects of hypospadias type, number of operations and surgical procedures on sexual psychology, sexual behaviour and sexual function. The control group consisted of 50 healthy adults. The postoperative SDS / SAS scores and occurrences of depression/anxiety in hypospadiac patients were significantly higher than those of normal controls (P < 0.001). Patients with proximal hypospadias and multiple procedures differed from those with distal hypospadias and a single procedure in all parameters of sexual psychology (P < 0.05). The average penile lengths and circumferences of hypospadiac patients under either erect or flaccid conditions were significantly shorter than those of normal controls (P < 0.001). A similar difference existed between patients with distal and proximal hypospadias (P < 0.01). There was no significant difference in any parameter of sexual function between patients with different numbers of operations and surgical procedures. Hypospadiac patients were clearly impaired in sexual psychology and penile development. The severity of hypospadias and number of operations were key factors that influenced the sexual psychology of patients. This finding indicated the importance of long-term follow-up and psychological counselling for hypospadiac patients postoperatively. PMID:19377489

    Introduction The aim of the study was to study the long-term effect on cardiovascular disease risk factors of stress from direct experience of an earthquake as a young person. Material and methods We selected workers born between July 1, 1958 and July 1, 1976 who were examined at Kailuan General Hospital between May and October of 2013. Data on cardiovascular events were taken during the workers’ annual health examination conducted between 2006 and 2007. All subjects were divided into three groups according to their experience of the Tangshan earthquake of July 28, 1976, as follows: control group; exposed group 1 and exposed group 2. We compared cardiovascular disease risk factors between the three groups as well as by gender and age. Results One thousand one hundred and ninety-six workers were included in the final statistical analysis. Among all subjects, resting heart rate (p = 0.003), total cholesterol (p < 0.001), and fasting blood glucose (p < 0.001) were significantly higher among those who experienced the earthquake compared with unexposed controls, but were unrelated to loss of relatives. No significant difference in triglyceride levels was observed between the three groups (p = 0.900). Further refinement showed that the effects were restricted to males 40 years of age or older at the time of analysis, but were due primarily to age at the time of earthquake exposure (p = 0.002, p < 0.001 and p = 0.002). Conclusions Earthquake experience in the early years of life has long-term effects on adult resting heart rate, total cholesterol, and fasting plasma glucose, especially among men. PMID:28144258

    We experienced a rare complication where extravasation developed a pseudo-chamber long after the balloon pulmonary angioplasty for supravalvular pulmonary stenosis. A 3-month-old girl was diagnosed with an anomalous origin of the left coronary artery from the pulmonary artery. She underwent the Takeuchi procedure at 10 months of age. During the follow-up, the supravalvular pulmonary stenosis deteriorated, and was treated by balloon pulmonary angioplasty with the double balloon technique catheter at 6 years of age. Angiography at the main pulmonary artery showed a small amount of extravasation contrast medium after the procedure. Follow-up echocardiography showed a diminished extravasation hemorrhage. Twelve years later, right ventricular enlargement due to pulmonary regurgitation had been observed on echocardiography. In addition, abnormal echo free space was detected at the left posterior of the left atrium. Enhanced computed tomography clearly demonstrated there was an orifice and extent of the pseudo-chamber. Surgical findings revealed a large tear just distal to the coronary tunnel. We speculated that extravasation blood was limited in the perivascular area early after the procedure but eventually reached the non-adhesive oblique pericardial sinus with age. Consequently, pulmonary to oblique pericardial sinus communication was established and looked like a pseudo-chamber long after the procedure. In conclusion, even if extravasation seems to be limited immediately after the balloon pulmonary angioplasty, it could expand for non-adhesive space and could develop a huge blood space like chamber. Long-term careful observation should be necessary for extravasation of pulmonary artery even with surgical adhesion.

    Deeply uncertain factors like climate change, the hydrologic impacts of urbanization, forest evolution, and long-term demand forecasts make water supply planning a `wicked' problem. The traditional technique of assessing risk based on historical observations can be inadequate in the face of environmental non-stationarity. However, competing models and limited observational data make it difficult for decision makers and experts to agree on how much uncertainty should be built into analyses of risk, particularly at the timescales relevant to long-term investments in water infrastructure. Further, the physical connectivity of these deeply uncertain processes create inter-related systems, amplifying the challenges of a `worst case scenario'. The development of adaptive systems and planning processes provide solutions that have been shown to meet technical, environmental, and social objectives at lower costs. Instead of developing plans with fixed targets for the timing of actions, adaptive plans develop risk metrics and thresholds that are able to integrate new information to determine when conditions reach a `tipping point' which necessitates action. It is an open question as to how new information can be best integrated into the decision-making process (i.e. how much weight do we give new observations relative to the historical record), but a better understanding of the way the relevant systems are expected to evolve and change over time could inform these decisions. In this study, we use linked, dynamic models of temperature and precipitation changes, forest evolution, urbanization, hydrology, and water demand to develop scenarios for an adaptive water management framework that uses risk-based metrics to make short- and long-term decisions. The impact of individual environmental processes on the adaptive capability of this management framework is evaluated through problem formulations that successively increase the complexity of the uncertainty scenarios.

CONCLUSIONS: Aortic valve replacement in the elderly can be performed with acceptable mortality. Significant preoperative risk factors for early mortality include poor left ventricular function and preoperative pacemaker insertion. Predictors of late mortality include chronic obstructive pulmonary disease and urgency of operation. These results stress the importance of operating on the elderly with aortic valve disease; both long-term survival and functional recovery are excellent. Images Figure 9. PMID:9230820

    To extensively investigate long-term unmet needs in survivors of stroke or TIA and to identify factors associated with these unmet needs. Community-dwelling adults were invited to participate in a survey ≥2 years after discharge for stroke/TIA. Unmet needs were assessed across 5 domains: activities and participation, environmental factors, body functions, post-acute care, and secondary prevention. Factors associated with unmet needs were determined with multivariable negative binomial regression. Of 485 participants invited to complete the survey, 391 (81%) responded (median age 73 years, 67% male). Most responders (87%) reported unmet needs in ≥1 of the measured domains, particularly in secondary prevention (71%). Factors associated with fewer unmet needs included older age (incident rate ratio [IRR] 0.62, 95% confidence interval [CI] 0.50-0.77), greater functional ability (IRR 0.33, 95% CI 0.17-0.67), and reporting that the general practitioner was the most important in care (IRR 0.69, 95% CI 0.57-0.84). Being depressed (IRR 1.61, 95% CI 1.23-2.10) and receiving community services after stroke (IRR 1.45, 95% CI 1.16-1.82) were associated with more unmet needs. Survivors of stroke/TIA reported considerable unmet needs ≥2 years after discharge, particularly in secondary prevention. The factors associated with unmet needs could help guide policy decisions, particularly for tailoring care and support services provided after discharge. © 2017 American Academy of Neurology.

    We report the long-term history of two patients with oropharyngeal dysphagia subsequent to partial resection of the larynx (supraglottic and subtotal laryngectomy, respectively). Both fiberendoscopic and videofluoroscopy swallowing studies demonstrated aspiration of liquids and solids in the lower respiratory tract. The patients underwent a swallowing rehabilitation program and respiratory exercises to improve the efficacy of their cough, and both continued oral feeding despite their persistent dysphagia. They were followed annually over the subsequent 12 and 9 years, respectively, which included overseeing the clinical status of their bronchopulmonary apparatus (i.e., whether a productive cough was present or not), nutritional status, spirometric parameters, arterial blood gas analysis, pulse oximetry, and measurement of cough effectiveness. They also underwent serial videofluoroscopy swallowing studies, which demonstrated persistent tracheobronchial aspiration of both liquids and solids. Based on the absence of respiratory hospitalizations as well as pulmonary deterioration during the follow-up period, we discuss the importance of cough effectiveness and its enhancement as a possible protective factor to avoid pulmonary morbidity in chronic aspiration.

    The objectives of this study were: (1) to describe the prevalence and 6-month incidence of observer-rated depression in residents age 65 and over of long-term care (LTC) facilities; (2) to describe risk factors for depression, at baseline and over time. A multisite, prospective observational study was conducted in residents aged 65 and over of 7 LTC facilities. The Cornell Scale for Depression in Dementia (CSDD) was completed by nurses monthly for 6 months. We measured demographic, medical, and functional factors at baseline and monthly intervals, using data from research assessments, nurse interviews, and chart reviews. 274 residents were recruited and completed baseline depression assessments. The prevalence of depression (CSDD score of 6+) was 19.0%. The incidence of depression among those without prevalent depression was 73.3 per 100 person-years. A delirium diagnosis, pain, and diabetes were independently associated with prevalent depression. CSDD score at baseline and development of severe cognitive impairment at follow-up were independent risk factors for incident depression. A diagnosis of delirium and uncorrected visual impairment at follow-up occurred concurrently with incident depression. The results of this study have implications for the detection and prevention of depression in LTC. Delirium diagnosis, pain and diabetes at baseline were associated with prevalent depression; depression symptoms at baseline and development of severe cognitive impairment at follow-up were risk factors for incident depression.

    To investigate nutrient limitation effect on the community metabolism of closed aquatic ecosystem and possible nutrient limiting factors in the experimental food chains, depletion of inorganic chemicals including carbon, nitrogen and phosphorous was tested. A closed aquatic ecosystem lab module consisting of Chlorella pyrenoidosa and Chlamydomonas reinhardtii, Daphnia magna and associated unidentified microbes was established. Closed ecological systems receive no carbon dioxide; therefore, we presumed carbon as a first limiting factor. The results showed that the algae population in the nutrient saturated group was statistically higher than that in the nutrient limited groups, and that the chlorophyll a content of algae in the phosphorus limited group was the highest among the limited groups. However, the nitrogen limited group supported the most Daphnia, followed by the carbon limited group, the nutrient saturated group and the phosphorus limited group. Redundancy analysis showed that the total phosphorus contents were correlated significantly with the population of algae, and that the amount of soluble carbohydrate as feedback of nutrient depletion was correlated with the number of Daphnia. Thus, these findings suggest that phosphorus is the limiting factor in the operation of closed aquatic ecosystem. The results presented herein have important indications for the future construction of long term closed ecological system.

    Chronic glomerular and tubular nephrotoxicity is reported in 20-50% and 20-25%, respectively, of children and adolescents treated with ifosfamide and 60-80% and 10-30%, respectively, of those given cisplatin. Up to 20% of children display evidence of chronic glomerular damage after unilateral nephrectomy for a renal tumour. Overall, childhood cancer survivors have a ninefold higher risk of developing renal failure compared with their siblings. Such chronic nephrotoxicity may have multiple causes, including chemotherapy, radiotherapy exposure to kidneys, renal surgery, supportive care drugs and tumour-related factors. These cause a wide range of chronic glomerular and tubular toxicities, often with potentially severe clinical sequelae. Many risk factors for developing nephrotoxicity, mostly patient and treatment related, have been described, but we remain unable to predict all episodes of renal damage. This implies that other factors may be involved, such as genetic polymorphisms influencing drug metabolism. Although our knowledge of the long-term outcomes of chronic nephrotoxicity is increasing, there is still much to learn, including how we can optimally predict or achieve early detection of nephrotoxicity. Greater understanding of the pathogenesis of nephrotoxicity is needed before its occurrence can be prevented.

    Background and purpose.In percutaneous placement of central venous catheters an inadvertent, direct lesion of the lung parenchyma can occur. This is a cause of iatrogenic pneumothorax, whose incidence is approximately 1 to 4%, largely dependent on the experience of the operator, the site of venipuncture and proba-bly the technique employed. Initial treatment currently ranges from observation alone to formal tube-thoracostomy. In an attempt to define the best initial treatment, if any, we reviewed our personal series and contributions from the literature. As a result we have produced a flow-chart proposing a rational treatment of this frequent complication. Patients and Methods.One thousand four hundred twenty-one ports were placed in patients at the Department of Surgery of the European Institute of Oncology in Milan through an infraclavicular standardized percutaneous subclavian approach. They were placed during the 60-month period from January 1, 1996 to December 31, 2000 for long-term chemotherapy treatment of solid tumours. Chest upright X-rays were obtained post-operatively in all cases to check the correct position of the catheter tip and the presence of pneumothorax. Results.Twenty-two patients out of 1421 (1.54%) experienced a radiologically-proven pneumothorax, ranging from 5 to 70% of the affected pleural space. Sixteen patients out of 22 (72.7%) with minor portions of affected pleural space received simple observation. In these patients the most common finding was an uncomplicated tachycardia (more than 100 beats/min); 8 of them did not complain of any symptoms. Six patients (27.2%) un-derwent an additional procedure (3 tube-thoracostomies and 3 aspirations of the pleural space), claiming symptoms of chest pain and various degrees of dyspnea. Tube thoracostomy was mainly adopted at the beginning of our experience, and in patients with a severe degree of pleural involvement (55 to 70% of the pleural space). Aspiration, instead, was used more recently and

    We tried to determine the risk factors for the long-term efficacy, recurrence, and metastasis of small hepatocellular carcinoma (HCC, diameter <5 cm). One hundred sixty-eight small liver cancer patients received percutaneous cryoablation therapy by argon-helium superconducting surgery system under the ultrasound guidance. Clinical parameter and the efficacy were analyzed after follow-up. After cryoablation treatment, the median follow-up time for the 168 patients was 36 (7-41) months. Liver functions were impaired as indicated by increased alanine aminotransferase, total bilirubin, total protein, albumin, and prothrombin activity. The difference of VEGF expression in liver cancer and the surrounding tissue is significant. 1-, 2-, and 3-year overall survival were 92.9, 83.9, and 65.5 %, respectively. Relapse-free survival was 76.8, 53.0, and 41.1 %. Less tumor number, higher tumor differentiation, and low VEGF expression predict higher metastasis-free and relapse-free survival rate. Lower Child-Pugh classification is correlated with the higher overall survival after cryoablation. There was no statistical significance in in situ intrahepatic recurrence patients, but VEGF changes were statistically significant for metastasis in other parts of liver or extrahepatic metastasis. Tumor number, differentiation, VEGF expression, large vessel invasion, lymph node, and extrahepatic metastasis all affect the overall and relapse-free survival. VEGF expression can be a predictable factor for liver cancer recurrence and metastasis.

    We apply the theoretical frameworks of knowledge transfer and organizational learning, and findings from studies of clinical practice guideline (CPG) implementation in health care, to develop a contingency model of innovation adoption in long-term care (LTC) facilities. Our focus is on a particular type of innovation, CPGs designed to improve the quality of LTC. Our interest in this area is founded on the premise that the ability of LTC organizations to adopt and sustain the use of innovations like CPGs is contingent on the initial capacity these institutions have to learn about them, and on the presence of factors that contribute to capacity building at each stage of innovation adoption. Based on our review of relevant theory, we develop a set of fifteen testable propositions that relate factors operating at the guideline, individual, organizational, and environmental levels in LTC institutions to stages of guideline adoption/transfer. Our model offers insights into the complexities of adopting and sustaining innovations in LTC facilities particularly, in health care organizations specifically, and in service organizations generally.

    Introduction While trials comparing antiplatelet strategies after coronary intervention report average risks of bleeding and ischemia in a population, there is limited information to guide choices based on individual patient risks, particularly beyond one year after treatment. Methods Patient-level data from PROTECT, a broadly inclusive trial enrolling 8709 subjects treated with drug-eluting stents (sirolimus vs. zotarolimus-eluting stent), and PROTECT US, a single arm study including 1018 subjects treated with a zotarolimus-eluting stent were combined. The risk of ischemic events, cardiovascular death/non-periprocedural myocardial infarction (MI)/definite or probable stent thrombosis and the risk of bleeding events, GUSTO moderate or severe bleed were predicted using logistic regression, and the correlation between predicted ischemic and bleeding risks within individual patients was estimated. Results At median follow-up of 4.1 years, major bleeding occurred in 260 subjects (2.8%), and ischemic events in 595 (6.3%). Multivariate predictors of bleeding were: older age, smoking, diabetes mellitus, congestive heart failure, and chronic kidney disease (all p<0.05). Ischemic events shared all of the same predictors with bleeding events as well as: sex, BMI, prior MI, prior CABG, STEMI on presentation, stent length and sirolimus-eluting stent use (all p<0.05). Within individual subjects, bleeding and ischemic risks were strongly correlated (ρ=0.76, p<0.001). 97% of subjects had a greater risk of ischemic events than bleeding. Conclusions Individual patient risks of ischemia and bleeding are related to many common risk factors, yet the predicted risks of ischemic events are greater than those of major bleeding in the large majority of patients in long-term follow-up.

    We aimed to assess long-term seizure outcome and risk factors for seizure recurrence in a cohort of patients who have undergone extratemporal resection for management of refractory seizures. Eighty-one patients underwent extratemporal resection at Austin Health, Melbourne, Australia (1991-2004). Seizure recurrence was any postoperative disabling seizure (complex partial seizure [CPS] ± secondary generalization). Multivariate Cox proportional hazards regression models examined potential preoperative and perioperative risk factors and the risk associated with early postoperative seizures (≤ 28 days postsurgery). The change between preoperative and postoperative seizure frequency was also measured. Median follow-up was 10.3 years (range 1-17.7). The probabilities of freedom from disabling seizures (on or off antiepileptic medication) were 40.7% (95% confidence interval [CI] 30-51) at 1 month, 23.5% (95% CI 15-33) at 1 year, and 14.7% (95% CI 8-23) at 5 years postoperative. Reduction of disabling seizures to at least 20% of preoperative frequency was attained by 57% of patients at 5 postoperative years. Of the preoperative/perioperative factors, focal cortical dysplasia (FCD) type 1 (hazard ratio [HR] 1.90, 95% CI 1.08-3.34, p = 0.025) and incomplete resection (HR 1.71, 95% CI 1.06-2.76, p = 0.028) were independent recurrence risks. After surgery, an early postoperative seizure was the only factor associated with higher risk (HR 4.28 [2.42-7.57], p = 0.00). Distinction between subtypes of focal cortical dysplasia, which can be made using magnetic resonance imaging (MRI) criteria, may be useful for preoperative prognostication. Early seizures after surgery are not benign and may be markers of factors that contribute to seizure recurrence. Most patients achieve substantial reduction in seizure frequency. Further study of the significance of this reduction in terms of surgical "success" or otherwise is required. Wiley Periodicals, Inc. © 2012 International League

    ). In their recent paper entitled 'An observational 71-year history of seasonally frozen ground changes in Eurasian high latitudes', Frauenfeld and Zhang (2011) provided detailed analysis of soil temperature data to assess 1930-2000 trends in seasonal freezing depth. The data were obtained from 387 Soviet non-permafrost meteorological stations. The authors performed systematic, quality-controlled, integrative analysis over the entire former Soviet Union domain. The long-term changes in depth of seasonal freezing were discussed in relation to such forcing variables as air temperature, degree days of freezing/thawing, snow depth and summer precipitation as well as modes of the North Atlantic Oscillation. The spatially average approach adopted for the study provides a generalized continental-scale trend. The study greatly improves, expands and extends previous 1956-90 analysis of the ground thermal regime over the Eurasian high latitudes (Frauenfeld et al 2004). Although the work of Frauenfeld and Zhang (2011) is the most comprehensive assessment of the continental-scale long-term trends in seasonal freezing available to date, more detailed analysis is needed to determine the effect of climate change on seasonally frozen ground. It should be noted that, in addition to the variables considered for analysis, other non-climatic factors affect the depth of freezing propagation. Unlike the surface, which is influenced by the climate directly, the ground even at shallow depth receives a climatic signal that is substantially modified by edaphic processes, contributing to highly localized thermal sensitivities of the ground to climatic forcing. Subsurface properties, soil moisture, and snow and vegetation covers influence the depth of freezing. Topography also plays an important role in establishing the ground thermal regime. It is an important determinant of the amount of heat received by the ground surface, affects the distribution of snow and vegetation, and influences the

    The reported rates of gestational diabetes mellitus are constantly escalating and little is known about long-term complications in the offspring. Evidence from the field of epigenetics strongly advocates the need for research on the neuropsychiatric complications in offspring prenatally exposed to gestational diabetes mellitus. We sought to assess whether in utero exposure to gestational diabetes mellitus increases the risk of long-term neuropsychiatric morbidity in the offspring. A population-based cohort study compared the incidence of hospitalizations due to neuropsychiatric disease between singletons exposed and unexposed to gestational diabetes mellitus. Deliveries occurred in the years 1991 through 2014 in a regional tertiary medical center. Perinatal deaths, multiple gestations, mothers with pregestational diabetes or lack of prenatal care, and children with congenital malformations were excluded from the study. A multivariate generalized estimating equation logistic regression model analysis was used to control for confounders and for maternal clusters. During the study period 231,271 deliveries met the inclusion criteria; 5.4% of the births were to mothers diagnosed with gestational diabetes mellitus (n = 12,642), of these 4.3% had gestational diabetes type A1 (n = 10,076) and 1.1% had gestational diabetes type A2 (n = 2566). During the follow-up period, a significant linear association was noted between the severity of the gestational diabetes (no gestational diabetes, gestational diabetes mellitus A1, gestational diabetes mellitus A2) and neuropsychiatric disease of the offspring (1.02% vs 1.36% vs 1.68%, respectively, P < .001). A Kaplan-Meier curve demonstrated that children born to women with gestational diabetes mellitus had higher cumulative incidence of neuropsychiatric morbidity. Using a generalized estimating equation multivariable logistic regression model, controlling for time-to-event, maternal age, gestational age at delivery, maternal

    Previous studies have shown that cancer survivors frequently experience short-term cognitive deficits, but it is unknown how long these deficits last or whether they worsen over time. Using a co-twin control design, the cognitive function of 702 cancer survivors aged 65 years and older was compared with that of their cancer-free twins. Dementia rates were also compared in 486 of the twin pairs discordant for cancer. Cancer survivors overall, as well as individuals who had survived cancer for 5 or more years before cognitive testing, were more likely than their co-twins to have cognitive dysfunction (odds ratio [OR] = 2.10, 95% confidence interval [CI] = 1.36 to 3.24; P<.001; and OR = 2.71, 95% CI = 1.47 to 5.01; P<.001, respectively). Cancer survivors were also twice as likely to be diagnosed with dementia as their co-twins, but this odds ratio did not reach statistical significance (OR = 2.0, 95% CI = 0.86 to 4.67; P = .10). These results suggest that cancer patients are at increased risk for long-term cognitive dysfunction compared with individuals who have never had cancer, even after controlling for the influence of genetic factors and rearing environment.

    We have analyzed different cosmophysical factors which have effect on long-term global temperature variations during solar cycles 20-24. A detailed analysis of total solar irradiance (TSI), the spectral solar ultraviolet emission (UV), space weather and cosmic rays (CRs) have effects on the atmosphere processes. We have shown that increasing of global temperature is likely affected by TSI and UV during solar maxima. During the descending phases of these solar cycles the interplanetary magnetic field and long-lasting solar wind high speed streams occurred frequently and were the primary contributors to minimize of CRs effect on the Earth's atmosphere. In this case global temperature is increased extra as result of increase in the atmosphere's transparency. We show that there are a few effective physical mechanisms of the action of solar activity and space weather on the global temperature. TSI and CRs play essential role in climate change and main part of climate variations can be explained by the mechanism of action TSI and CRs modulated by the solar activity on the state of lower atmosphere and meteorological parameters.

    Urinary tract infection is the most common type of bacterial infection in kidney transplant procedures, with adverse effects on graft and patient survival. We aimed to evaluate the risk factors of recurrent urinary tract infection in renal transplant recipients and its impact on patient and graft survival. In a cohort of 1019 patients who were transplanted between 2000 and 2010 at Hamed Al-Essa Organ Transplant Center in Kuwait, 86% developed at least 1 episode of urinary tract infection, with only 6.2% of patients having recurrent infections. We compared patients with recurrent urinary tract infections (group 1) with those who had no recurrence (group 2) regarding their risk factors. Patients in group 1 were significantly younger than those in group 2 (34.9 ± 23 vs 42.8 ± 16 y; P < .001), with female preponderance (P < .001). The percentage of patients with thymoglobulin induction (21.5%) was significantly higher in group 1. Patients with pretransplant urologic problems experienced significantly more recurrent urinary tract infections (P < .001). Hepatitis C infections were significantly more prevalent among group 1 (10.8% vs 3.8%; P = .008). Long-term graft outcome (functioning and failed) were 78.5% and 21.5% in group 1 versus 85.1% and 13.9% in group 2 (P = .18). Patient outcomes (living and deceased donors) were 98.4% and 1.6% in group 1 versus 95.7% and 4.3% in group 2 (P = .187). Adult females, thymoglobulin induction, pretransplant urologic problems, and hepatitis C infection were the risk factors of recurrent urinary tract infection among our renal transplant patients. However, recurrence did not adversely affect graft or patient survival.

Survival curves in the two different histotypes (intestinal and mixed/diffuse) were superimposed in the first three years of follow-up and diverged thereafter. Likewise, survival curves as a function of site (fundus vs body/antrum) started to diverge after the first year. On the contrary, survival curves differed among age classes from the very beginning, due to different post-operative mortality, which increased from 0.5% in patients aged 65-74 years to 9.9% in patients aged 75-91 years; this discrepancy later disappeared. Accordingly, the proportional hazards assumption of the Cox model was violated, as regards age, site and histology. To cope with this problem, multivariable survival analysis was performed by separately considering either the first two years of follow-up or subsequent years. Histology and site were significant predictors only after two years, while T and N, although significant both in the short-term and in the long-term, became less important in the second part of follow-up. Increasing age was associated with higher mortality in the first two years, but not thereafter. Splitting survival time when performing survival analysis allows to distinguish between short-term and long-term risk factors. Alternative statistical solutions could be to exclude post-operative mortality, to introduce in the model time-dependent covariates or to stratify on variables violating proportionality assumption.

There are realisable benefits of EHR adoption in LTC facilities; however, there is limited research about this topic. The purpose of this systematic literature review is to identify EHR adoption factors for LTC facilities that are ineligible for the HITECH Act incentives. We conducted systematic searches of Cumulative Index of Nursing and Allied Health Literature (CINAHL) Complete via Ebson B. Stephens Company (EBSCO Host), Google Scholar and the university library search engine to collect data about EHR adoption factors in LTC facilities since 2009. Search results were filtered by date range, full text, English language and academic journals (n=22). Multiple members of the research team read each article to confirm applicability and study conclusions. Researchers identified common themes across the literature: specifically facilitators and barriers to adoption of the EHR in LTC. Results identify facilitators and barriers associated with EHR adoption in LTC facilities. The most common facilitators include access to information and error reduction. The most prevalent barriers include initial costs, user perceptions and implementation problems. Similarities span the system selection phases and implementation process; of those, cost was the most common mentioned. These commonalities should help leaders in LTC facilities align strategic decisions to EHR adoption. This review may be useful for decision-makers attempting successful EHR adoption, policymakers trying to increase adoption rates without expanding incentives and vendors that produce EHRs.

    The objective of this report was to estimate long-term outcome and prognostic factors in children and adolescents who presented with metastatic osteosarcoma at diagnosis. Patients were treated in six French pediatric oncology centers with surgery and multiagent chemotherapy, mainly with high-dose methotrexate. Their medical records were reviewed retrospectively. The medical records of patients who were treated for metastatic osteosarcoma from 1987 to 2000 were reviewed. Patients were treated with the chemotherapy regimens recommended for nonmetastatic disease in children (the French Society of Pediatric Oncology OS 87 and OS 94 protocols) or, in a few patients, with other chemotherapy regimens. Surgical excision of the primary tumor and, when possible, of all metastatic sites was performed based on a personalized assessment of each patient's situation. Seventy-eight patients age < 20 years were treated. Forty-six patients (59%) had only 1 metastatic site (35 to the lungs and 11 to bone). Twenty-eight patients (36%) achieved a complete remission after combination chemotherapy and surgery. The event-free survival and overall survival rates at 5 years were 14% and 19%, respectively. To date, 14 patients (18%) have remained alive with a median follow-up of 112 months. Pretreatment features associated with a shorter event-free survival in the multivariate analysis were metastasis to at least two organs and high alkaline phosphatase level. Patients with at least 1 of these poor prognostic factors had a 2.6% event-free survival rate at 5 years despite treatment. The survival of patients with metastatic osteosarcoma were treated with conventional chemotherapy and surgery remained very poor. Patients should be classified into different prognostic groups and treated accordingly. New therapeutic approaches are warranted to improve the prognosis for patients with the most severe disease.

    Aim An exploratory study of the relationship between cumulative exposure to subcutaneous (sc) interferon (IFN) β-1a treatment and other possible prognostic factors with long-term clinical outcomes in relapsing–remitting multiple sclerosis (RRMS). Methods Patients in the original PRISMS study were invited to a single follow-up visit 15 years after initial randomisation (PRISMS-15). Outcomes over 15 years were compared in the lowest and highest quartile of the cumulative sc IFN β-1a dose groups, and according to total time receiving sc IFN β-1a as a continuous variable per 5 years of treatment. Potential prognostic factors for outcomes were analysed. Results Of 560 patients randomised in PRISMS, 291 returned for PRISMS-15 and 290 (51.8%) were analysed. Higher cumulative dose exposure and longer treatment time appeared to be associated with better outcomes on: annualised relapse rate, number of relapses, time to Expanded Disability Status Scale (EDSS) progression, change in EDSS, proportions of patients with EDSS ≥4 or ≥6, ≤5 relapses and EDSS <4 or <6, and time to conversion to secondary-progressive MS (SPMS). Higher dose exposure was associated with lower proportions of patients with EDSS progression and conversion to SPMS, and longer time on treatment with lower risk of first relapse. Change in EDSS from baseline to 24 months was a strong predictor of evaluated clinical outcomes over 15 years. Conclusions These findings suggest that higher cumulative exposure to sc IFN β-1a may be associated with better clinical outcomes, and early change in EDSS score may have prognostic value, over many years, in RRMS.

    An exploratory study of the relationship between cumulative exposure to subcutaneous (sc) interferon (IFN) β-1a treatment and other possible prognostic factors with long-term clinical outcomes in relapsing-remitting multiple sclerosis (RRMS). Patients in the original PRISMS study were invited to a single follow-up visit 15 years after initial randomisation (PRISMS-15). Outcomes over 15 years were compared in the lowest and highest quartile of the cumulative sc IFN β-1a dose groups, and according to total time receiving sc IFN β-1a as a continuous variable per 5 years of treatment. Potential prognostic factors for outcomes were analysed. Of 560 patients randomised in PRISMS, 291 returned for PRISMS-15 and 290 (51.8%) were analysed. Higher cumulative dose exposure and longer treatment time appeared to be associated with better outcomes on: annualised relapse rate, number of relapses, time to Expanded Disability Status Scale (EDSS) progression, change in EDSS, proportions of patients with EDSS ≥ 4 or ≥ 6, ≤ 5 relapses and EDSS <4 or <6, and time to conversion to secondary-progressive MS (SPMS). Higher dose exposure was associated with lower proportions of patients with EDSS progression and conversion to SPMS, and longer time on treatment with lower risk of first relapse. Change in EDSS from baseline to 24 months was a strong predictor of evaluated clinical outcomes over 15 years.

  13. Formaldehyde in residences: long-term indoor concentrations and influencing factors.

    Chronic human exposure to formaldehyde is significantly increased by indoor sources. However, information is lacking on why these exposures appear to persist in older homes with aging sources. We use data from the Relationships of Indoor, Outdoor, and Personal Air study to evaluate 179 residences, most of which were older than 5 years. We assess the dependence of indoor formaldehyde concentrations (C(in)) on building type and age, whole-house air exchange rate, indoor temperature, and seasonal changes. Indoor formaldehyde had mean and median concentrations of 17 ppb, and primarily originated from indoor sources. The factors we analyzed did not explain much of the variance in C(in), probably because of their limited influence on mechanisms that control the long-term release of formaldehyde from aging pressed-wood products bound with urea-formaldehyde (UF) resins. We confirmed that the mitigating effects of ventilation on C(in) decrease with time through the analysis of data for new homes available in the literature, and through models. We also explored source control strategies and conclude that source removal is the most effective way to decrease chronic exposures to formaldehyde in existing homes. For new homes, reducing indoor sources and using pressed-wood with lower UF content are likely the best solutions. Formaldehyde concentrations in homes due to indoor sources appear to persist throughout the lifetime of residences. Increases in ventilation rates are most effective in decreasing indoor concentrations in new homes where formaldehyde levels are high or when homes are tight. Consequently, other alternatives need to be promoted such as decreasing the amount of pressed-wood products with urea-formaldehyde (UF) resins in homes or reducing the UF content in these materials.

    The clinical course and aluminum status of 38 patients who had been receiving dialysis for at least eight years and were still undergoing dialysis in 1985 were evaluated. Twenty-nine had evidence of increased aluminum burden, although only three had evidence of overt aluminum toxicity, and nine did not have evidence of increased aluminum burden. The patients in both the high- and low-aluminum group were similar with regard to age, the cause of their renal failure, presence of hypertension or coronary artery disease, previous parathyroidectomy, and a number of biochemical parameters, along with the amount of prescribed aluminum. All patients were followed up for the next two years or until they died. The amount of ingested aluminum was reduced, and in selected patients, treatment with intermittent infusions of deferoxamine mesylate was instituted. There were no deaths in the low-aluminum group, but ten of 29 died in the high-aluminum group: seven of vascular disease and three of infection. In addition, morbidity as defined by hospitalization for coronary or cerebral vascular disease or infection occurred in only two of the nine patients in the low-aluminum group and in 19 of the 29 patients in the high-aluminum group. These observations imply that the occurrence of increased body aluminum, as suggested by aluminum blood levels or by results of bone biopsies in some patients, has an adverse effect on morbidity and mortality and should be considered as a possible independent risk factor in patients who are receiving long-term hemodialysis.

    Hyperlipidemia (HL) is a common problem in adult renal transplant (TP) recipients, contributing to an increased risk of cardiovascular disease and chronic TP nephropathy. There are multiple causes of HL post renal TP in adult patients, including pre TP HL, immunosuppressive agents, renal dysfunction, hypoalbuminemia secondary to nephrotic syndrome, obesity, and conditions that lead to end-stage renal disease (ESRD). We evaluated the incidence and risk factors of HL in 62 pediatric renal TP recipients (15.4+/-4.2 years, range-3.0-22.3 years) with long-term (6.7+/-3.1 years) functioning [glomerular filtration rate (GFR) 66.7+/-23.2 ml/min per 1.73 m(2)] allografts. The mean serum cholesterol (C) level was 205. 5+/-43.6 mg/dl. Thirty-two patients (51.6%) exhibited elevated serum C levels. The mean serum triglyceride (TG) level was 157.3+/-88.4 mg/dl. Serum TG levels were elevated in 32 patients (51.6%). In patients with elevated serum levels of either C or TG, the mean low-density lipoprotein level (LDL) was 138.6+/-44.1 mg/dl (normal <130 mg/dl) and the high-density lipoprotein (HDL) level 54.6+/-15.9 mg/dl (normal>34 mg/dl). Of those patients studied, 45.5% had high LDL levels, whereas 9.1% exhibited low HDL levels. The two risk factors for elevated serum C levels in our patient population were pre-TP HL and increased years since TP. The only risk factor for elevated serum TG levels was reduced GFR. A family history of HL had a significant deleterious impact upon serum levels of C (P=0.01), but did not affect serum TG levels (P=0.7). Years on dialysis prior to TP, history of prior TP, gender, body mass index, and disease leading to ESRD had no influence upon the development of post-TP HL. We conclude that post-renal TP HL is a significant problem in pediatric renal TP recipients.

    Auditory complications are an adverse event of childhood cancer treatment, especially common in children treated with platinum chemotherapy or cranial radiation. Variation between diagnostic childhood cancer groups has rarely been studied, and we do not know if the burden of auditory complications has changed over the last decades. Within the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to all survivors who were diagnosed at age 16 years or less between 1976 and 2005. We compared prevalence of self-reported hearing loss and tinnitus between all diagnostic childhood cancer groups and siblings, used multivariable logistic regression to analyze the effect of treatment-related factors on hearing loss, and compared the cumulative incidence of hearing loss between different periods of cancer diagnosis. Prevalence of self-reported hearing loss was higher in survivors (10%) than in siblings (3%, P < 0.001), and highest in survivors of central nervous system tumors (25%). Significant risk factors were treatment with platinum compounds (carboplatin: odds ratio [OR] 2.4; cisplatin: OR 9.4), cranial radiation (>29 Gy: OR >1.7), or brain surgery (OR 2.2). Children diagnosed in 1986-1995, when platinum compounds came into widespread use, had a significantly higher cumulative incidence of hearing loss than those diagnosed in 1976-1985. In the most recent period, 1996-2005, the risk decreased again, both for patients treated with platinum compounds and with cranial radiation. Our data show that the burden of hearing loss has stabilized in recently treated survivors, suggesting that survivors have benefited from new treatment regimens that use less ototoxic radiation and more carefully dosed platinum compounds. © 2016 Wiley Periodicals, Inc.

    Patients with long-term complications of sulfur mustard (SM) poisoning are often less able to undertake optimum levels of physical activity and adequately control their dietary intake. The aim of present study was to investigate the dietary intake of patients with SM poisoning in comparison to a control group Methods: The study was undertaken on 55 Iranian male veterans, who had > 25% disabilities due to long-term complications of SM poisoning and 55 men age-matched healthy subjects. A previously validated food frequency questionnaire (FFQ) was used for measuring dietary macro/micro nutrient intake for both groups; and the results were analysed using Dietplan6 software. Analysis of macro/micro nutrients in dietary intakes of the patients versus the controls showed a significantly lower intake of several nutrients including selenium and carbohydrate. On the other hand, the dietary intake of trans-fatty acids and iodine were significantly higher in these patients. Long-term complications of SM poisoning in the Iranian veterans induce both chemical and physical disabilities. Macro/micro nutrient intake in these patients was significantly different in comparison with matched, healthy subjects. Dietary advice for these patients should be strongly recommended to these patients in order to prevent other chronic diseases.

    The use of central venous catheters for long-term hemodialysis has been associated with increased mortality and high prevalence of infection and venous stenosis. However, because central venous catheters still constitute a significant proportion of vascular access in prevalent populations, even in the Fistula-First era, the authors examined the long-term patient outcomes and performance of this vascular access type to inform current clinical practice. The authors conducted a retrospective cohort study of 433 patients on maintenance hemodialysis in a dialysis program from January 1999 through April 2008 all using twin-catheter Tesio Caths (TCs) (MedCOMP, Harleysville, Pennsylvania). Written and electronic records were examined with respect to laboratory indices as well as mortality, access-related infection, need for thrombolytic infusion, access revision and dialysis adequacy. A total of 759 TCs were inserted with 552,035 catheter days follow-up. Thirty-six percent of insertions were in patients incident to dialysis (< 90 days). Mean single-pool Kt/V was 1.6 ± 0.3. Cumulative cohort survival rates were 85%, 72%, and 48% at 1, 2, and 5 years, respectively. No patients died as a result of lack of vascular access. Cumulative assisted primary access site patencies were 76%, 62%, and 42% at 1, 2, and 5 years, respectively. The prevalence of symptomatic central venous stenosis was 5%. Catheter-related bacteremia occurred at a rate of 0.34 per 1,000 catheter days. Appropriate use of TCs with protocolized care can deliver effective long-term hemodialysis with good adequacy and rates of access-related infection approaching those seen with arteriovenous grafts.

    Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autosomal dominantly inherited autoinflammatory disease caused by mutations in the TNFRSF1A gene. Treatment is aimed at preventing acute disease attacks, improving quality of life, and preventing long-term complications such as systemic reactive amyloidosis. Biologic agents have significantly improved TRAPS management. In particular, interleukin 1 (IL-1) inhibition either with the recombinant IL-1 receptor antagonist anakinra or with the human IgG1 anti-IL-1β monoclonal antibody canakinumab has recently shown to induce a prompt and stable disease remission. Conversely, the successful experience with IL-6 inhibition is nowadays limited to a single patient. Anyway, introduction of new treatment options for patients requiring a lifelong therapy is desirable. We describe two TRAPS patients (son and father) successfully treated with canakinumab and tocilizumab, respectively. In particular, we highlight the clinical and laboratory efficacy as well as the good safety profile of tocilizumab during a 42-month follow-up period.

    Understanding factors associated with undiagnosed obstructive lung disease and its impact on mortality could inform the ongoing discussions about benefits and risks of screening and case finding. To define factors associated with undiagnosed obstructive lung disease and its long-term mortality. Cross-sectional analysis of participants, aged 20 to 79 years, in two National Health and Nutritional Examination Surveys (NHANES), NHANES III (1988-1994) and NHANES 2007-2012, with longitudinal follow-up of NHANES III participants. We classified participants with spirometry-confirmed obstructive disease, based on the fixed ratio definition (FEV1/FVC < 0.7), as "diagnosed" (physician diagnosis of either asthma or chronic obstructive pulmonary disease), and "undiagnosed" (no recorded physician diagnosis). For the longitudinal analysis of NHANES III participants, mortality was the outcome of interest. We tested the contribution of self-reported health status and comorbidity burden (exposure) to the odds of being undiagnosed using logistic models adjusted for demographics, smoking status, and lung function. We estimated hazard ratios (HRs) for all-cause mortality for diagnosed and undiagnosed subjects participating in NHANES III who had spirometry using Cox- proportional regression analysis. Among those with spirometry-defined obstruction, 71.2% (SE, 1.8) in NHANES III and 72.0% (SE, 1.9) in NHANES 2007-2012 were undiagnosed. In multivariate models, undiagnosed obstructive disease was consistently associated in both surveys with self-reported good/excellent health status, lower comorbidity burden, higher lung function, and being of racial/ethnic minority. Among NHANES III participants (median follow up, 14.5 yr), both undiagnosed (HR, 1.23; 95% confidence interval, 1.08-1.40) and correctly diagnosed participants (HR, 1.74; 95% confidence interval, 1.45-2.09) had higher risk for all-cause mortality than participants without obstruction.

    Increasing scarcity of donated liver grafts clearly demonstrates the desperate need for ongoing outcome analysis to improve patient and graft survival after liver transplantation. Coagulation is often severely deteriorated in patients suffering from liver disease, thus leading to bleeding complications after liver transplantation. We included 770 liver transplantations in this single-center retrospective analysis to identify independent risk factors for post-operative hemorrhage. The relevance of bleeding complications was assessed with special regards to coagulation-related variables. Multivariate regression analyses allowed weighing of different risk factors. Post-operative hemorrhage leading to revision surgery was observed in 19.9% (n=153 cases) of cases and was revealed as an independent risk factor for mortality (p=0.014; HR: 1.457; 95%-CI: 1.081-1.964). Risk-adjusted multivariate regression analysis compiling all pre- and intra-operative donor and recipient variables revealed that only the number of transfused packed red blood cells (p<0.001; OR: 1.072; 95%-CI: 1.036-1.110), hepatitis B virus-related liver disease (p=0.019; OR: 0.082; 95%-CI: 0.010-0.666), model of end-stage liver disease-era (p=0.020; OR: 1.016; 95%-CI: 1.002-1.029), partial thromboplastin time at transplantation (p=0.021; OR: 1.016; 95%-CI: 1.002-1.029), and donor intensive care unit stay in days (p=0.009; OR: 1.009; 95%-CI: 1.002-1.016) were significantly associated with the occurrence of post-operative hemorrhage. Post-operative hemorrhage relevantly contributed post-transplant mortality. Avoidance of excessive packed red blood cell use during transplantation and short donor-intensive care unit stay lead to a decreased rate of bleeding complications. Coagulations state at transplantation is also relevant for favorable outcome.

  4. Long-term cumulative survival and mechanical complications of single-tooth Ankylos Implants: focus on the abutment neck fractures

    2015-01-01

    PURPOSE To evaluate the cumulative survival rate (CSR) and mechanical complications of single-tooth Ankylos® implants. MATERIALS AND METHODS This was a retrospective clinical study that analyzed 450 single Ankylos® implants installed in 275 patients between December 2005 and December 2012. The main outcomes were survival results CSR and implant failure) and mechanical complications (screw loosening, fracture, and cumulative fracture rate [CFR]). The main outcomes were analyzed according to age, sex, implant length or diameter, bone graft, arch, and position. RESULTS The 8-year CSR was 96.9%. Thirteen (2.9%) implants failed because of early osseointegration failure in 3, marginal bone loss in 6, and abutment fracture in 4. Screw loosening occurred in 10 implants (2.2%), and 10 abutment fractures occurred. All abutment fractures were located in the neck, and concurrent screw fractures were observed. The CSR and rate of screw loosening did not differ significantly according to factors. The CFR was higher in middle-aged patients (5.3% vs 0.0% in younger and older patients); for teeth in a molar position (5.8% vs 0.0% for premolar or 1.1% for anterior position); and for larger-diameter implants (4.5% for 4.5 mm and 6.7% for 5.5 mm diameter vs 0.5% for 3.5 mm diameter) (all P<.05). CONCLUSION The Ankylos® implant is suitable for single-tooth restoration in Koreans. However, relatively frequent abutment fractures (2.2%) were observed and some fractures resulted in implant failures. Middle-aged patients, the molar position, and a large implant diameter were associated with a high incidence of abutment fracture. PMID:26813443

    2007-01-01

    We conducted a prospective randomized study to investigate predictive factors for short- and long-term outcome of anterior cervical decompression and fusion (ACDF) as measured by current pain intensity on the Visual Analogue Scale (VAS) and by disability using the Neck Disability Index (NDI). Current understanding about how preoperative and short-term outcome data predict long-term outcome is sparse, and there are few studies involving analysis of short-term follow-up using multivariate approaches with quantification of the relative importance of each variable studied. A total of 95 patients were randomly allocated for ACDF with the cervical intervertebral fusion cage or the Cloward procedure. The mean follow-up time was 19 months (range 12–24) for short-term follow-up and 76 months (range 56–94 months) for long-term. Background factors, radiologically detected findings, physiological measurements, treatment type, pain, and disability were used as potential predictors. Multivariate statistical analysis by projection to latent structures was used to investigate predictors of importance for short- and long-term outcome of ACDF. A “preoperative” low disability and pain intensity, non-smoking status, male sex, good hand strength, and an active range of motion (AROM) in the neck were significant predictors for good short- and long-term outcomes. The short-term outcome data were better at predicting long-term outcome than were baseline data. Radiologically detected findings and surgical technique used were mainly insignificant as predictors. We suggest that the inclusion criteria for ACDF should be based on a bio-psycho-social model including NDI. NDI may also be regarded as an important outcome measurement in evaluation of ACDF.

    To describe the long-term experience of a simplified frozen elephant trunk technique (sFETT) used in complicated acute type A aortic dissection (AAAD) treatment. Between January 2001 and December 2012, 34 patients (mean age 59.9 ± 11.0 years) with complicated AAAD (DeBakey I) underwent an emergency surgery including sFETT. sFETT consisted in gluing the dissected aortic arch wall layers with gelatine-resorcinol adhesive and video-assisted antegrade open arch aortic stent-graft deployment in the arch or proximal descending aorta. In addition to sFETT, the aortic root was addressed with standard techniques. A 30-day mortality was 14.7% (five patients) due to bleeding (1), multiple organ failure (2), and colon ischemia (2). Postoperative morbidity included neurological (2), renal (1) and cardio-pulmonary complications (4), as well as wound infection (1). Mean follow-up was 74.4 ± 45.0 months. Actual survival rates were 73.5% at 1 year, 70.2% at 5 years, and 58.5% at 13 years of follow-up. Six patients died during long-term follow-up from heart failure (1) and unknown reasons (5). Five patients required reoperation for aortic arch (3) or aorto-iliac (2) progression of aneurysm during the mid- and long-term follow-up. The remaining patients showed favorable evolution of the dissected aorta with false lumen occlusion in most cases and stable aortic diameters. In AAAD patients, sFETT as used in our series is an easy and safe technique to repair the aortic arch. Long-term results after sFETT showed false lumen occlusion and stable aortic diameter in up to 13 years of follow-up. © The Author(s) 2016.

    Six skin collagen advanced glycation end products (AGEs) originally measured near to the time of the Diabetes Control and Complications Trial (DCCT) closeout in 1993 may contribute to the "metabolic memory" phenomenon reported in the follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study. We have now investigated whether the addition of four originally unavailable AGEs (i.e., glucosepane [GSPNE], hydroimidazolones of methylglyoxal [MG-H1] and glyoxal, and carboxyethyl-lysine) improves associations with incident retinopathy, nephropathy, and neuropathy events during 13-17 years after DCCT. The complete 10-AGE panel is associated with three-step Early Treatment of Diabetic Retinopathy Study scale worsening of retinopathy (P ≤ 0.002), independent of either mean DCCT or EDIC study A1C level. GSPNE and fructose-lysine (furosine [FUR]) correlate with retinopathy progression, independently of A1C level. The complete panel also correlates with microalbuminuria (P = 0.008) and FUR with nephropathy independently of A1C level (P ≤ 0.02). Neuropathy correlates with the complete panel despite adjustment for A1C level (P ≤ 0.005). MG-H1 and FUR are dominant, independent of A1C level (P < 0.0001), whereas A1C loses significance after adjustment for the AGEs. Overall, the added set of four AGEs enhances the association of the original panel with progression risk of retinopathy and neuropathy (P < 0.04) but not nephropathy, while GSPNE and MG-H1 emerge as the principal new risk factors. Skin AGEs are robust long-term markers of microvascular disease progression, emphasizing the importance of early and sustained implementation of intensive therapy.

    Aims. This study assessed factors associated with glycemic control among Saudi patients with Type 2 diabetes mellitus (T2DM). Methods. We conducted an analytical cross-sectional study, which included a random sample of 288 patients with T2DM proportional to the diabetes population of each primary health care center in Jazan city, Kingdom of Saudi Arabia. Results. More than two-thirds (74%) of patients had poor glycemic control. Lack of education, polypharmacy, and duration of diabetes ≥ 7 years were significantly associated with higher glycated hemoglobin (HbA1c). Moreover, patients who were smoker or divorced were significantly more likely to have higher HbA1c. The patients who did not comply with diet or take their medications as prescribed had poor glycemic control. The study found lower HbA1c levels among patients who received family support or had close relationship with their physicians. Similarly, knowledgeable patients towards diabetes or those with greater confidence in ability to manage self-care behaviors had a lower HbA1c. In contrast, risk factors such as depression or stress were significantly correlated with poorer glycemic control. Conclusion. The majority of T2DM patients had poor glycemic control. The study identified several factors associated with glycemic control. Effective and tailored interventions are needed to mitigate exposure to these risk factors. This would improve glycemic control and reduce the risks inherent to diabetes complications. PMID:28090538

    Right-sided retroperitoneoscopic living donor nephrectomy (LDN) has been shown to be safe for the donor but it is unknown whether the short renal vein is associated with complications or an impaired long-term outcome in the recipient. In this retrospective cohort study, consecutive transplant recipients after retroperitoneoscopic LDN were enrolled. Complications occurring within 1 year were classified according to the Clavien-Dindo Classification for Surgical Complications and analysed using multivariable logistic regression. Predictors of 1-year creatinine clearance were analysed with multivariable linear regression. Cox proportional hazard models were used to analyse graft survival. Of the 251 recipients, 193 (77%) received a left kidney and 58 (23%) a right kidney. Surgical complications of Clavien-Dindo grade 3 or higher were comparable in recipients of right and left kidneys (33% vs 29%, odds ratio 0.98, 95% confidence interval [CI] 0.50, 1.94). The occurrence of a surgical complication had a significant impact on creatinine clearance at 1 year (decrease of 6 ml/min/m2, p = 0.016). Vascular complications in right kidneys were more common but were all corrected without impact on graft survival. One-year graft-survival was similar in recipients of right (98.3%) and left (96.9%) kidneys, as was creatinine clearance one year after transplantation (mean difference 3.3 ml/min/m2, 95% CI -1.5, 8.1; p = 0.175). After a median follow-up of 5 years, neither the side (hazard ratio 1.56, 95% CI 0.67, 3.63) nor surgical complications (hazard ratio 1.44, 95% CI 0.65, 3.19) were associated with graft failure. Right retroperitoneoscopic LDN does not compromise the outcome of transplantation. Surgical complications, long-term graft function and graft survival were comparable in right and left kidneys.

    Background Substantial complication rates after postmastectomy breast reconstruction (BR) in breast cancer patients have been reported. Few studies have reported on the resulting psychological distress (PD) and satisfaction with the aesthetic result in relation to postoperative complications after completion of implant or DIEP flap BR. The present study investigated whether women were able to recover from complication related distress in the long term. Methods PD was prospectively measured using questionnaires regarding anxiety, depression and cancer distress. Eligible patients completed questionnaires before BR (T0, n = 144), after one month (T1, n = 139) and after completion of BR, approximately 21 months after initial reconstructive surgery (T2, n = 119). Satisfaction with the aesthetic result was assessed 21 months after BR. Data concerning complications, subsequent additional surgery and total reconstruction failure up to T2 were collected from the medical records. Analyses were performed using multi-level regression analyses correcting for age. Results One or more complications occurred in 61 patients (42%) and 50 women required subsequent surgery (35%). In time, mean PD significantly declined towards baseline scores independent of complications. However, a total reconstruction failure (n = 10) was significantly associated with a large temporary increase in depression scores. After additional surgery due to complications patients were less satisfied with aesthetic outcome, although patient satisfaction was independent of PD. Conclusions PD outcomes generally declined to normal levels after completion of the entire BR course. Patients experiencing a total reconstruction failure reported more depression after this loss, but in the long term recovered to the same level as women without complications. These findings indicate that women generally can cope efficiently with these serious adverse events, even if they were less satisfied with the aesthetic result

    Background The present study aimed to evaluate and determine the factors that affect short- and long-term outcome following manipulation under anaesthesia (MUA) of patients with adhesive capsulitis. Methods Patients recruited from January 1999 to January 2010 were retrospectively analyzed and classified as having primary or secondary adhesive capsulitis. All patients were assessed for range of movement (ROM) and Oxford Shoulder Scores (OSS) before and immediately postoperatively, as well as for OSS more than 1 year post MUA. Results In total, 295 patients (315 shoulders) were sequentially recruited, and information was collected at baseline, as well as at a mean follow-up of 28 days and 3.6 years. A significant improvement in OSS and ROM was noted 1 month post MUA (p < 0.0001) with females benefiting more than males (p < 0.0025). Long-term follow-up revealed that the improvement in OSS was maintained (p < 0.0001). Secondary adhesive capsulitis significantly reduced the efficacy of MUA as assessed by ROM (p < 0.0001). Other factors (age, initial ROM and OSS, and length of symptoms prior to MUA) did not significantly affect the outcome over the short- or long-term. Conclusions The findings of the present study show that all patient groups had a significantly improved ROM and OSS in the short-term with long-term maintenance of improved OSS. PMID:27582942

    Former studies that have attempted to characterize individual socio-demographic factors associated with long-term benzodiazepine use were based on relatively small sample sizes and/or self-reported data. Our aim was to clarify this using large-scale primary health care data from Sweden. The present study covered 71 primary health care centres containing individual-level data from a total of 919, 941 individuals who visited a primary health care centre (PHCC) during the period 2001-2007. From this database we selected individuals 25 years or older with depression, anxiety and/or insomnia and who were prescribed a benzodiazepine within 0-90 as well as 91-270 days after their first clinical diagnosis of depression, anxiety and/or insomnia. Older age (OR, 2.92, 95% CI, 2.28-3.84), middle SES (OR, 1.22, 95% CI, 1.08-1.38), being on social welfare (OR, 1.40, 95% CI, 1.23-1.62) and not being married were associated with higher long-term benzodiazepine use. The PHCCs only explained a small part of the individual variation in long-term benzodiazepine use. Awareness of the impact on long-term benzodiazepine use of certain individual-level socio-demographic factors is important for health care workers and decision-makers who should aim at targeting general interventions at all primary health care centres.

    Device closure of atrial septal defect (ASD) and patent foramen ovale (PFO) are both associated with short- and long-term complications. Our knowledge of the complication rates of ASD and PFO closure is limited. Our objective was to review the peri-procedural and long-term complications of ASD and PFO closure. Medline, EMBASE, and Scopus databases were searched between 1973 and 2012. A total of 28,142 patients from 203 case series were included. Of these 203 articles, 111 were reporting ASD closure, 61 were reporting PFO closure, and 31 were reporting both. Pooled incidence rates of cardiac complications were calculated separately for peri-procedural and at follow-up. Peri-procedural major complications were reported from 0% to 9.4%, with a pooled estimate rate of 1.4% (95% CI: 1.3-1.6%). It was 1.6% (95% CI: 1.4-1.8%) in ASD group, 1.1% (95% CI: 0.9-1.3%) in PFO group, and 1.3% (95% CI: 0.9-1.9%) in ASD/PFO group. The most common major complication was the device embolization requiring surgery. Peri-procedural minor complications were reported with a pooled estimate rate of 1.4% (95% CI: 1.2-1.7%). It was 1.6% (95% CI: 1.2-2.1%) in ASD group, 1.3% (95% CI: 1.0-1.7%) in PFO group, and 1.5% (95% CI: 1.1-1.2.1%) in ASD/PFO group. The most frequent major complications at follow-up were cerebrovascular events [1.3% (95% CI: 1.1-1.6%)] and device thrombosis [1.2% (95% CI: 1.0-1.4%)]. Both were more frequent in PFO group. Device closure of ASD and PFO are associated with non-negligible serious complications, both in early and long-term. Copyright © 2013 Wiley Periodicals, Inc.

    Transanal endoscopic microsurgery (TEM) is a consolidated technique for the excision of rectal tumors. However, many aspects relating to its morbidity, risk of functional alterations, and therapeutic outcomes are still unclear. The aim of this study was to assess the rate of morbidity and fecal incontinence after TEM, and to identify associated risk factors. We prospectively recorded the clinical data of 157 patients who underwent TEM from 1996 to 2013. Among these, 89 patients answered a questionnaire for the assessment of fecal continence at a median follow-up time of 40 months. Intraoperative and postoperative TEM complication rates were 3.8 and 20.4%. The mortality rate was 0.6%. A distance from the anal verge of more than 6 cm correlated with a higher risk of perforation, while patients with cancer were more likely to have postoperative bleeding. Incontinence was reported by 32 (36%) patients, of which 7 (8%) experienced transitory symptoms only, while 25 (28%) reported persistent symptoms. We found a correlation between patients receiving preoperative radiotherapy (RT) and the development of fecal incontinence. The recurrence rate was 3% (1/32) in pT1, 80% (4/5) in pT2, and 100% (1/1) in pT3. After radiotherapy, 7% (1/9) showed a good response (pT0-1), and 18% (2/7) showed no response (pT2-3). TEM is associated with low morbidity but the risk of developing functional alterations is not negligible and should be discussed with the patient before the operation. Good oncological outcomes are possible for early invasive cancers and for selected advanced cancers following a good response to preoperative RT.

    Limited data exist on long-term revision rates following cervical spine arthrodeses. The purposes of this study were to define reoperation rates after primary cervical arthrodeses and to identify risk factors for revisions. New York State's all-payer health-care database was queried to identify all primary subaxial cervical arthrodeses occurring in the 16 years from 1997 through 2012. A total of 87,042 patients were included in the study cohort. Demographic information was extracted. Patients' preoperative medical comorbidities, surgical indications, and operative approaches were assembled using codes from the ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification). The cohort was followed to revision surgical procedures, death, or the end of the study period. All subsequent contiguous spinal arthrodeses, including in the subaxial cervical spine, were considered revisions. The overall revision risk and the risk associated with various preoperative characteristics, surgical indications, and operative approaches were assessed using a Cox proportional hazard model. During the study period, 6,721 patients (7.7%) underwent revision. The median time to revision was 24.5 months. The probability of undergoing at least one revision by 192 months was 12.6%. Arthrodeses performed via anterior-only approaches had a significantly higher probability of revision (p < 0.001) at 13.4% (95% confidence interval [95% CI], 12.9% to 13.9%) than those performed via posterior approaches at 7.4% (95% CI, 6.6% to 8.4%) or circumferential (anterior and posterior) approaches at 5.2% (95% CI, 4.0% to 6.8%). This relationship persisted in multivariate analysis; compared with anterior surgical procedures, there was a significantly lower risk of revision (p < 0.001) for posterior surgical approaches at a hazard ratio of 0.76 (95% CI, 0.69 to 0.84) and circumferential approaches at a hazard ratio of 0.53 (95% CI, 0.42 to 0.66). Patient age of 18 to 34 years

    Atypical and malignant meningiomas are rare. Our aim was to examine the treatment outcomes following surgical resection, and analyze associations between clinical characteristics and overall survival (OS) or relapse free survival (RFS). 102 patients with atypical or malignant meningiomas underwent microsurgical resection between June 2001 and November 2009 were analyzed retrospectively. We compared demographics, clinical characteristics, treatment, and complications. The five-year and ten-year overall survival rates were 93.5% and 83.4%, respectively. Three factors significantly reduced OS: Malignant meningiomas (p < 0.001), which also decreased RFS (p < 0.001); female patients (p = 0.049), and patients with Karnofsky Performance Status (KPS) < 70 at diagnosis (p = 0.009). Fifty two patients (51%) experienced tumor relapse. Total resection of tumors significantly impacted RFS (p = 0.013). Tumors located at parasagittal and posterior fossa area lead to higher relapse rate (p = 0.004). Subtotal resection without adjuvant radiotherapy lead to the worst local control of tumor (p = 0.030). An MIB-1 index <8% improved OS and RFS (p = 0.003). Total resection of atypical and malignant meningiomas provided better outcome and local control. Adjuvant radiation therapy is indicated for patients with malignant meningiomas, with incompletely excised tumors; or with tumors in the parasagittal or posterior fossa area. The MIB-1 index of the tumor is an independent prognostic factor of clinical outcome. PMID:27760993

    Microalbuminuria is a common diagnosis in the clinical care of patients with type 1 diabetes mellitus. Long-term outcomes after the development of microalbuminuria are variable. We quantified the incidence of and risk factors for long-term renal outcomes after the development of microalbuminuria in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. The DCCT randomly assigned 1441 persons with type 1 diabetes to intensive or conventional diabetes therapy, and participants were subsequently followed up during the observational EDIC study. During the DCCT/EDIC study, 325 participants developed incident persistent microalbuminuria (albumin excretion rate, ≥30 mg/24 h at 2 consecutive study visits). We assessed their subsequent renal outcomes, including progression to macroalbuminuria (albumin excretion rate, ≥300 mg/24 h at 2 consecutive visits), impaired glomerular filtration rate (estimated glomerular filtration rate, <60 mL/min/1.73 m(2) at 2 consecutive study visits), end-stage renal disease, and regression to normoalbuminuria (albumin excretion rate, <30 mg/24 h at 2 consecutive visits). The median follow-up period after persistent microalbuminuria diagnosis was 13 years (maximum, 23 years). Ten-year cumulative incidences of progression to macroalbuminuria, impaired glomerular filtration rate, end-stage renal disease, and regression to normoalbuminuria were 28%, 15%, 4%, and 40%, respectively. Albuminuria outcomes were more favorable with intensive diabetes therapy, lower glycated hemoglobin level, absence of retinopathy, female sex, lower blood pressure, and lower concentrations of low-density lipoprotein cholesterol and triglycerides. Lower glycated hemoglobin level, absence of retinopathy, and lower blood pressure were also associated with decreased risk of impaired glomerular filtration rate.

    Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) is the standard approach for the management of biliary complications in liver transplant patients; however, its safety and efficacy have not been established in this setting. This study was performed to evaluate the safety and long-term efficacy of ERCP in transplant patients. Methods The case reports of 1,500 liver transplant patients were reviewed. Orthotopic liver transplantation (OLT) patients were matched 1:2 with non-OLT patients and followed-up for long-term outcome (median, 7.4 years). Results Of the 1,500 liver transplant patients, 94 (6.3%) underwent 150 ERCPs after OLT. Anastomotic strictures were present in 45 patients, biliary stones in 24, biliary leaks in 7, papillary stenosis in 2, and primary sclerosing cholangitis in 1. An ERCP success rate of 90.7% was achieved; biliary stenting led to resolution of the bile leak in 7/7 (100%) patients, and biliary stones were removed in 21/24 (87.5%) patients. In addition, 34 of 45 patients with anastomotic stricture underwent endoscopic dilation. We obtained complete resolution in 22/34 (64.7%) patients. OLT patients did not show a higher probability of complications (odds ratio [OR], 1.04), of pancreatitis (OR, 0.80) or of bleeding (OR, 1.34). Conclusions ERCP is safe and effective for the treatment of post-OLT biliary complications, has a low rate of pancreatitis and results in a durable effect. PMID:21927662

    Infection, mainly related to vascular access, is one of the main causes of morbidity and a preventable cause of death in hemodialysis patients. From January 1994 to April 1998 we conducted a prospective study to assess the incidence and risk factors of catheter-related bacteremia. One hundred and twenty-nine tunneled dual-lumen hemodialysis catheters were inserted percutaneously into the internal jugular vein in 89 patients. Bacteremia (n = 56) occurred at least once with 37 (29%) of the catheters (an incidence of 1.1/1,000 catheter-days); local infection (n = 45, 1/1,000 catheter-days) was associated with bacteremia in 18 cases. Death in 1 case was directly related to Staphylococcus aureus (SA) septic shock, and septicemia contributed to deaths in 2 additional cases. Catheters were removed in 48% of the bacteremic episodes. Treatment comprised intravenous double antimicrobial therapy for 15-20 days. Bacteriological data of bacteremia showed 55% involvement of SA. Nasal carriage of SA was observed in 35% of the patients with catheters. Bacteremic catheters were more frequently observed in patients with diabetes mellitus (p = 0.03), peripheral atherosclerosis (p = 0.001), a previous history of bacteremia (p = 0.05), nasal carriage of SA (p = 0.0001), longer catheter survival time (p = 0.001), higher total intravenous iron dose (p = 0.001), more frequent urokinase catheter infusion (p < 0.01), and local infection (p < 0.001) compared with non-bacteremic catheters. Monovariate survival analysis showed that significant initial risk factors for bacteremia were nasal carriage of SA (p = 0.00001), previous bacteremia (p = 0.0001), peripheral atherosclerosis (p = 0.005), and diabetes (p = 0.04). This study confirms the relatively high incidence of bacteremia with tunneled double-lumen silicone catheters and its potential complications. Possible preventive actions are discussed according to the risk factors.

    The aim of this study was to examine the association of specific personal and environmental factors with eating performance among long-term care residents with moderate-to-severe cognitive impairment. Eating is the one of the most basic and easiest activities of daily living to perform. While multilevel factors can be associated with eating performance, the evidence among those with dementia was insufficient. A secondary analysis of baseline data collected between March and September in 2012 from 199 residents in eight long-term care facilities. Eating performance was conceptualized using the single self-care 'feeding' item in the Barthel Index and was scored based on four levels of dependence and assistance required. Binary logistic regression was used to examine the adjusted association of specific factors with eating performance. Almost one-third of the residents needed help with eating. After adjusting the type of facility, number of comorbidities, chair-sitting balance, agitation and depression, compromised eating performance was associated with severe cognitive impairment and low physical capability. This study supported the association of eating performance with cognitive impairment and physical capability among long-term care residents with moderate-to-severe cognitive impairment. Targeted interventions should be implemented to reduce the impact of cognitive decline on eating performance and promote physical capability to optimize eating performance. Future work need to use validated multiple-item measures for eating performance and test the association of personal and environmental factors with eating performance among a larger heterogeneous group of long-term care residents to enhance understanding of the factors. © 2015 John Wiley & Sons Ltd.

    Purpose: The use of altered fractionation radiotherapy (RT) regimens, as well as concomitant chemotherapy and RT, to intensify therapy for locally advanced head-and-neck cancer can lead to increased rates of long-term dysphagia. Methods and Materials: We identified 122 patients who had undergone definitive RT for locally advanced head-and-neck cancer, after excluding those who had been treated for a second or recurrent head-and-neck primary, had Stage I-II disease, developed locoregional recurrence, had <12 months of follow-up, or had undergone postoperative RT. The patient, tumor, and treatment factors were correlated with a composite of 3 objective endpoints as a surrogate for severe long-term dysphagia: percutaneous endoscopic gastrostomy tube dependence at the last follow-up visit; aspiration on a modified barium swallow study or a clinical diagnosis of aspiration pneumonia; or the presence of a pharyngoesophageal stricture. Results: A composite dysphagia outcome occurred in 38.5% of patients. On univariate analysis, the primary site (p = 0.01), use of concurrent chemotherapy (p = 0.01), RT schedule (p = 0.02), and increasing age (p = 0.04) were significantly associated with development of composite long-term dysphagia. The use of concurrent chemotherapy (p = 0.01), primary site (p = 0.02), and increasing age (p = 0.02) remained significant on multivariate analysis. Conclusion: The addition of concurrent chemotherapy to RT for locally advanced head-and-neck cancer resulted in increased long-term dysphagia. Early intervention using swallowing exercises, avoidance of nothing-by-mouth periods, and the use of intensity-modulated RT to reduce the dose to the uninvolved swallowing structures should be explored further in populations at greater risk of long-term dysphagia.

    Gastric volvulus is an extremely rare late complication of pneumonectomy. We report the case of a 61-year-old man who presented with a 1-year history of progressive intolerance of solids and weight loss 33 years after a left pneumonectomy. Preoperative examinations showed a mesenteroaxial gastric volvulus. We performed a laparoscopic Toupet fundoplication and anterior gastropexy, following which his symptoms disappeared.

    Dual-energy X-ray absorption (DEXA) is commonly used to measure bone mineral density (BMD), bone mineral content (BMC), and body composition data (fat mass and lean mass) for phenotype assessment in mice. We were interested in the long-term development of BMD, BMC, lean mass, and fat mass of mice, also taking into account sex and genetic background. The dataset was used to analyze correlations among the different parameters. We analyzed males and females from inbred strains C3HeB/FeJ and C57BL/6J, starting from 42 until 528 days of age. To evaluate the effect of husbandry systems, we repeated a part of the study in a second facility with a different caging system. We also assessed different DEXA settings and repeatability of the scans. The results of this study were used to draw conclusions for the use of DEXA analysis in mouse phenotyping approaches.

    The CO2 emissions from a building's power system will change over the life time of the building, and this need to be taken into account to verify whether a building is Zero Emission (ZEB) or not. This paper describes how conversion factors between electricity demand and emissions can be calculated for the European power system in a long term perspective through the application of a large scale electricity market model (EMPS). Examples of two types of factors are given: a conversion factor for average emissions per kWh for the whole European power system as well as a marginal factor for a specific region.

    Coronary angioplasty frequently creates a thrombogenic surface, with subsequent mural thrombosis that may lead to acute complications and possibly stimulates the development of restenosis. Whether coumarins can prevent these complications is unclear. The objective of this open, randomized trial was to assess the clinical effect of coumarins started before coronary angioplasty and continued for 6 months. Before coronary angioplasty, 530 patients were randomly assigned to aspirin plus coumarins and 528 patients to aspirin alone. At the start of the angioplasty, the mean international normalized ratio was 2.7+/-1.1; during follow-up, it was 3.0+/-1.1. At 30 days, the composite end point of death, myocardial infarction, target-lesion revascularization, and stroke was observed in 18 patients (3.4%) treated with aspirin plus coumarin compared with 34 patients (6.4%) treated with aspirin alone (relative risk, 0.53; 95% CI, 0.30 to 0.92). At 1 year, these figures were 14.3% and 20.3%, respectively (relative risk, 0.71; 95% CI, 0.54 to 0.93). The incidence of major bleeding and false aneurysm during hospitalization was 3.2% and 1.0%, respectively (relative risk, 3.39; 95% CI, 1.26 to 9.11). The benefit of coumarins was observed in both stented and nonstented patients. Coumarins in addition to aspirin started before PTCA and continued for 6 months was more effective than aspirin alone in the prevention of acute and late complications after coronary angioplasty. This benefit was accompanied by a small but significant increase in bleeding complications.

    Neurosurgeons are often asked to perform open biopsy for diagnosis of encephalitis after medical investigations are non-diagnostic. These patients may be critically ill with multiple comorbidities. Patients and their families often request data regarding the success rates and complication profile of biopsy, but minimal literature exists in this area. Retrospective chart review of all patients undergoing open brain biopsy (burr hole or craniotomy) for encephalitis refractory to medical diagnosis between January 2009 and December 2013 was undertaken. Pathology records and outpatient follow-up were reviewed to determine most recent clinical status of each patient. A total of 59 patients were included with mean follow up of 20months. The average age at biopsy was 55years. The most common unconfirmed diagnoses leading to biopsy were vasculitis (44%), neoplasm (27%), infection (12%), autoimmune (12%), amyloidosis (5%). Tissue pathology was diagnostic in 42% of all cases. Overall, biopsy confirmed the preoperative diagnosis in 46% of cases and refuted the preoperative leading diagnosis in 25% of cases. At last follow-up, the tissue pathology resulted in a medical treatment change in 25% of cases. There was a 14% major neurological complication rate (postoperative stroke, hemorrhage, or neurological deficit) and 9% cardiopulmonary complication rate (delayed extubation and re-intubation) attributable to surgical intervention. In this limited series, diagnostic utility of biopsy in patients with idiopathic encephalitis is less than 50% and the major complication rate is 23%. Patients and providers must be counseled accordingly and weigh the risks and benefits of open biopsy for encephalitis cautiously.

    Objective The long-term effects of enzyme-replacement therapy (ERT) in Fabry disease are unknown. Thus, the aim of this study was to determine whether ERT in patients with advanced Fabry disease affects progression towards ‘hard’ clinical end-points in comparison with the natural course of the disease. Methods A total of 40 patients with genetically proven Fabry disease (mean age 40 ± 9 years; n = 9 women) were treated prospectively with ERT for 6 years. In addition, 40 subjects from the Fabry Registry, matched for age, sex, chronic kidney disease stage and previous transient ischaemic attack (TIA), served as a comparison group. The main outcome was a composite of stroke, end-stage renal disease (ESRD) and death. Secondary outcomes included changes in myocardial left ventricular (LV) wall thickness and replacement fibrosis, change in glomerular filtration rate (GFR), new TIA and change in neuropathic pain. Results During a median follow-up of 6.0 years (bottom and top quartiles: 5.1, 7.2), 15 events occurred in 13 patients (n = 7 deaths, n = 4 cases of ESRD and n = 4 strokes). Sudden death occurred (n = 6) only in patients with documented ventricular tachycardia and myocardial replacement fibrosis. The annual progression of myocardial LV fibrosis in the entire cohort was 0.6 ± 0.7%. As a result, posterior end-diastolic wall thinning was observed (baseline, 13.2 ± 2.0 mm; follow-up, 11.4 ± 2.1 mm; P < 0.01). GFR decreased by 2.3 ± 4.6 mL min−1 per year. Three patients experienced a TIA. The major clinical symptom was neuropathic pain (n = 37), and this symptom improved in 25 patients. The event rate was not different between the ERT group and the untreated (natural history) group of the Fabry Registry. Conclusion Despite ERT, clinically meaningful events including sudden cardiac death continue to develop in patients with advanced Fabry disease. PMID:23586858

    Abstract Background In spite of significant improvement after multi-modality treatment, prognosis of most patients with glioblastoma remains poor. Standard clinical prognostic factors (age, gender, extent of surgery and performance status) do not clearly predict long-term survival. The aim of this case-control study was to evaluate immuno-histochemical and genetic characteristics of the tumour as additional prognostic factors in glioblastoma. Patients and methods Long-term survivor group were 40 patients with glioblastoma with survival longer than 30 months. Control group were 40 patients with shorter survival and matched to the long-term survivor group according to the clinical prognostic factors. All patients underwent multimodality treatment with surgery, postoperative conformal radiotherapy and temozolomide during and after radiotherapy. Biopsy samples were tested for the methylation of MGMT promoter (with methylation specific polymerase chain reaction), IDH1 (with immunohistochemistry), IDH2, CDKN2A and CDKN2B (with multiplex ligation-dependent probe amplification), and 1p and 19q mutations (with fluorescent in situ hybridization). Results Methylation of MGMT promoter was found in 95% and in 36% in the long-term survivor and control groups, respectively (p < 0.001). IDH1 R132H mutated patients had a non-significant lower risk of dying from glioblastoma (p = 0.437), in comparison to patients without this mutation. Other mutations were rare, with no significant difference between the two groups. Conclusions Molecular and genetic testing offers additional prognostic and predictive information for patients with glioblastoma. The most important finding of our analysis is that in the absence of MGMT promoter methylation, longterm survival is very rare. For patients without this mutation, alternative treatments should be explored. PMID:27904447

    Chronic expanding hematoma is a rare pathology, which has not been previously described as a complication of gunshot injury with retained bullet fragments. Because of the similar characteristics of chronic expanding hematoma to malignancy, it can present a diagnostic challenge for clinicians. Imaging and biopsy evaluation is needed to reach a conclusive diagnosis and implement appropriate treatment. In this case report, we will discuss the development, diagnosis, and management of a chronic superficial cervicothoracic mass in a patient who presented 30 years post-gunshot injury with retained bullet fragments.  PMID:27917326

    Glucocorticoid receptor (GR) polymorphisms modulate glucocorticoid (GC) sensitivity and are associated with altered metabolic profiles. To evaluate the presence of GR polymorphisms (BclI (rs41423247), N363S (rs56149945), ER22/23EK (rs6189/rs6190), and 9β (rs6198) and investigate their associations with metabolic alterations in patients in long-term remission of Cushing's syndrome (CS). Cross-sectional case-control study. Sixty patients in long-term remission of CS were genotyped. Associations between GR polymorphisms and multiple vascular, body composition and metabolic parameters were investigated. Allelic frequencies of the polymorphisms and their associations with several cardiometabolic risk factors. This study shows that carriers of the 9β polymorphism have a higher systolic blood pressure and lower resistin levels. The GC sensitizing BclI polymorphism is associated with an adverse cardiometabolic risk factor profile: higher fat percentages of extremities and legs, higher serum leptin and E-selectin levels, and higher intima media thickness in carriers versus non-carriers. The 9β and BclI polymorphisms of the GR adversely affect the cardiometabolic profile in patients who are in remission after the treatment of CS. This suggests that genetically altered GC sensitivity modulates the long-term adverse cardiometabolic effects resulting from (endogenous) hypercortisolism.

    Guanine nucleotide exchange factors (GEFs) activate small GTPases that are involved in several cellular functions. cAMP-guanine nucleotide exchange factor II (cAMP-GEF II) acts as a target for cAMP independently of protein kinase A (PKA) and functions as a GEF for Rap1 and Rap2. Although cAMP-GEF II is expressed abundantly in several brain areas including the cortex, striatum, and hippocampus, its specific function and possible role in hippocampal synaptic plasticity and cognitive processes remain elusive. Here, we investigated how cAMP-GEF II affects synaptic function and animal behavior using cAMP-GEF II knockout mice. We found that deletion of cAMP-GEF II induced moderate decrease in long-term potentiation, although this decrease was not statistically significant. On the other hand, it produced a significant and clear impairment in NMDA receptor-dependent long-term depression at the Schaffer collateral-CA1 synapses of hippocampus, while microscopic morphology, basal synaptic transmission, and depotentiation were normal. Behavioral testing using the Morris water maze and automated IntelliCage system showed that cAMP-GEF II deficient mice had moderately reduced behavioral flexibility in spatial learning and memory. We concluded that cAMP-GEF II plays a key role in hippocampal functions including behavioral flexibility in reversal learning and in mechanisms underlying induction of long-term depression.

    Objective To analyze the late complications after endovascular graft repair of elective abdominal aortic aneurysms (AAAs) at the authors’ institution since November 1992. Summary Background Data Recently, the use of endovascular grafts for the treatment of AAAs has increased dramatically. However, there is little midterm or long-term proof of their efficacy. Methods During the past 9 years, 239 endovascular graft repairs were performed for nonruptured AAAs, many (86%) in high-risk patients or in those with complex anatomy. The grafts used were Montefiore (n = 97), Ancure/EVT (n = 14), Vanguard (n = 16), Talent (n = 47), Excluder (n = 20), AneuRx (n = 29), and Zenith (n = 16). All but the AneuRx and Ancure repairs were performed as part of a U.S. phase 1 or phase 2 clinical trial under a Food and Drug Administration investigational device exemption. Procedural outcomes and follow-up results were prospectively recorded. Results The major complication and death rates within 30 days of endovascular graft repair were 17.6% and 8.5%, respectively. The technical success rate with complete AAA exclusion was 88.7%. During follow-up to 75 months (mean ± standard deviation, 15.7 ± 6.3 months), 53 patients (22%) died of unrelated causes. Two AAAs treated with endovascular grafts ruptured and were surgically repaired, with one death. Other late complications included type 1 endoleak (n = 7), aortoduodenal fistula (n = 2), graft thrombosis/stenosis (n = 7), limb separation or fabric tear with a subsequent type 3 endoleak (n = 1), and a persistent type 2 endoleak (n = 13). Secondary intervention or surgery was required in 23 patients (10%). These included deployment of a second graft (n = 4), open AAA repair (n = 5), coil embolization (n = 6), extraanatomic bypass (n = 4), and stent placement (n = 3). Conclusion With longer follow-up, complications occurred with increasing frequency. Although most could be managed with some form of endovascular reintervention, some

    Restorative sleep is an important component of quality of life. Disturbances in sleep after burn injury were reported but all based on uncontrolled or nonstandardized data. The occurrence and the effect of long-term sleep problems in young adult burn survivors have not been well defined. This 5-year (2003-2008) prospective multicenter longitudinal study included adults with burn injuries ages 19 to 30 years who completed the Young Adult Burn Outcome Questionnaire (YABOQ) up to 36 months after injury. The items measured 15 patient-reported outcomes including physical, psychological, and social statuses and symptoms such as itch and pain. Scores of these 15 YABOQ outcome domains were standardized to a mean of 50 and a SD of 10 based on an age-matched nonburned reference group of young adults. Sleep quality was assessed using the item 'How satisfied are you now with your sleep,' rated by a 5-point Likert scale. Patients responding with very and somewhat dissatisfied were classified as having sleep dissatisfaction and the remaining as less or not dissatisfied. The associations between sleep dissatisfaction (yes/no) and YABOQ outcome domains were analyzed longitudinally using mixed-effect generalized linear models, adjusted for %TBSA burned, age, gender, and race. Generalized estimating equations were used to take into account correlated error resulting from repeated surveys on each patient over time. One hundred and fifty-two burn survivors participated in the YABOQ survey at baseline and during the follow-up who had at least one survey with a response to the sleep item. Among them, sleep dissatisfaction was twice as prevalent (76/152, 50%) when compared with the nonburned reference group (29/112, 26%). The likelihood of a burn survivor being dissatisfied with sleep was reduced over time after the burn injury. Sleep dissatisfaction following burns was significantly associated, in a dose-dependent manner, with increasing burn size (P = .001). Better sleep was associated

    The present study assesses the septic, thrombotic and hepatic complications and also the quality of life of patients with home parenteral nutrition (NPD in its Spanish acronym). The case histories of patients treated with NPD at our hospital were collected for the period January, 1986, to January, 2001. We had 20 patients, mean age 48 +/- 14 years (mean +/- SD), with a total catheterization time of 16,292 days. The main causes of intestinal failure were mesenteric ischaemia and radical enteritis. Quality of life was assessed by means of the Sickness Impact Profile (SIP) and the Karnofsky Index (KI). We found a catheter infection rate of 0.42 per 100 days of catheter, mostly produced by coagulase-negative staphylococci (63%). In 30% of the cases, it was necessary to remove the catheter, including in all cases produced by Candida. Cather occlusion rate was 0.05 per 100 days. Five patients presented an increase in transaminases and alkaline phosphatase, and one female patient developed cholestasis. Two patients died of NPD-related causes. The results of the quality of life analysis showed it was moderately affected, with SIP scores of 14.6 +/- 3.5 and KI results of 70 +/- 20 (mean +/- SD). Home parenteral nutrition allows a greater survival in cases of intestinal failure. The most frequent complication is an infection of the catheter. The results of the quality of life analysis in our series reveal it was moderately affected in most cases.

    Neurotoxic anticancer drugs, such as platinum-based anticancer drugs, taxanes, vinca alkaloids, and proteasome/angiogenesis inhibitors are responsible for chemotherapy-induced peripheral neuropathy (CIPN). The health consequences of CIPN remain worrying as it is associated with several comorbidities and affects a specific population of patients already impacted by cancer, a strong driver for declines in older adults. The purpose of this review is to present a comprehensive overview of the long-term effects of CIPN in cancer patients and survivors. Pathophysiological mechanisms and risk factors are also presented. Neurotoxic mechanisms leading to CIPNs are not yet fully understood but involve neuronopathy and/or axonopathy, mainly associated with DNA damage, oxidative stress, mitochondria toxicity, and ion channel remodeling in the neurons of the peripheral nervous system. Classical symptoms of CIPNs are peripheral neuropathy with a “stocking and glove” distribution characterized by sensory loss, paresthesia, dysesthesia and numbness, sometimes associated with neuropathic pain in the most serious cases. Several risk factors can promote CIPN as a function of the anticancer drug considered, such as cumulative dose, treatment duration, history of neuropathy, combination of therapies and genetic polymorphisms. CIPNs are frequent in cancer patients with an overall incidence of approximately 38% (possibly up to 90% of patients treated with oxaliplatin). Finally, the long-term reversibility of these CIPNs remain questionable, notably in the case of platinum-based anticancer drugs and taxanes, for which CIPN may last several years after the end of anticancer chemotherapies. These long-term effects are associated with comorbidities such as depression, insomnia, falls and decreases of health-related quality of life in cancer patients and survivors. However, it is noteworthy that these long-term effects remain poorly studied, and only limited data are available such as in

    Purpose To evaluate the long-term efficacy of ciliary neurotrophic factor delivered via an intraocular encapsulated cell implant for the treatment of retinitis pigmentosa (RP). Design Long-term follow up of a multicenter, sham-controlled study. Methods Thirty-six patients at three CNTF4 sites were randomly assigned to receive a high- or low- dose implant in one eye and sham surgery in the fellow eye. The primary endpoint (change in visual field sensitivity at 12 months) has been reported previously.1 Here we report long-term visual acuity, visual field and optical coherence tomography (OCT) outcomes in 24 patients either retaining or explanting the device at 24 months relative to sham-treated eyes. Results Eyes retaining the implant showed significantly greater visual field loss from baseline than either explanted eyes or sham eyes through 42 months. By 60 months and continuing through 96 months, visual field loss was comparable among sham-treated eyes, eyes retaining the implant and explanted eyes, as was visual acuity and OCT macular volume. Conclusions Over the short term, ciliary neurotrophic factor released continuously from an intra-vitreal implant lead to loss of total visual field sensitivity that was greater than the natural progression in the sham-treated eye. This additional loss of sensitivity related to the active implant was reversible when the implant was removed. Over the long term (60 – 96 months), there was no evidence of efficacy for visual acuity, visual field sensitivity or OCT measures of retinal structure. PMID:27457255

    The precise contribution of IORT to the management of locally advanced and recurrent colorectal cancer (CRC) remains uncertain. We performed a systematic review and meta-analysis to assess the value of IORT in this setting. Studies published between 1965 and 2011 that reported outcomes after IORT for advanced or recurrent CRC were identified by an electronic literature search. Studies were assessed for methodological quality and design, and evaluated for technique of IORT delivery, oncological outcomes, and complications following IORT. Outcomes were analysed with fixed-effect and random-effect model meta-analyses and heterogeneity and publication bias examined. 29 studies comprising 14 prospective and 15 retrospective studies met the inclusion criteria and were assessed, yielding a total of 3003 patients. The indication for IORT was locally advanced disease in 1792 patients and locally recurrent disease in 1211 patients. Despite heterogeneity in methodology and reporting practice, IORT is principally applied for the treatment of close or positive margins. When comparative studies were evaluated, a significant effect favouring improved local control (OR 0.22; 95% CI = 0.05-0.86; p = 0.03), disease free survival (HR 0.51; 95% CI = 0.31-0.85; p = 0.009), and overall survival (HR 0.33; 95% CI = 0.2-0.54; p = 0.001) was noted with no increase in total (OR 1.13; 95% CI = 0.77-1.65; p = 0.57), urologic (OR 1.35; 95% CI = 0.84-2.82; p = 0.47), or anastomotic complications (OR 0.94; 95% CI = 0.42-2.1; p = 0.98). Increased wound complications were noted after IORT (OR 1.86; 95% CI = 1.03-3.38; p = 0.049). Despite methodological weaknesses in the studies evaluated, our results suggest that IORT may improve oncological outcomes in advanced and recurrent CRC. Copyright © 2012 Elsevier Ltd.

    This study compared alcohol septal ablation (ASA) and surgical myectomy for periprocedural complications and long-term clinical outcome in patients with symptomatic hypertrophic obstructive cardiomyopathy. Debate remains whether ASA is equally effective and safe compared with myectomy. All procedures performed between 1981 and 2010 were evaluated for periprocedural complications and long-term clinical outcome. The primary endpoint was all-cause mortality; secondary endpoints consisted of annual cardiac mortality, New York Heart Association functional class, rehospitalization for heart failure, reintervention, cerebrovascular accident, and myocardial infarction. A total of 161 patients after ASA and 102 patients after myectomy were compared during a maximal follow-up period of 11 years. The periprocedural (30-day) complication frequency after ASA was lower compared with myectomy (14% vs. 27%, p = 0.006), and median duration of in-hospital stay was shorter (5 days [interquartle range (IQR): 4 to 6 days] vs. 9 days [IQR: 6 to 12 days], p < 0.001). After ASA, provoked gradients were higher compared with myectomy (19 [IQR: 10 to 42] vs. 10 [IQR: 7 to 13], p < 0.001). After multivariate analysis, age (per 5 years) (hazard ratio: 1.34 [95% confidence interval: 1.08 to 1.65], p = 0.007) was the only independent predictor for all-cause mortality. Annual cardiac mortality after ASA and myectomy was comparable (0.7% vs. 1.4%, p = 0.15). During follow-up, no significant differences were found in symptomatic status, rehospitalization for heart failure, reintervention, cerebrovascular accident, or myocardial infarction between both groups. Survival and clinical outcome were good and comparable after ASA and myectomy. More periprocedural complications and longer duration of hospital stay after myectomy were offset by higher gradients after ASA. Copyright © 2014 American College of Cardiology Foundation.

    Recurrent respiratory illnesses are frequent in infants following repair of esophageal atresia and functional abnormalities of respiratory and esophageal function are often seen in older children. Recurrent aspiration is a potential cause of these respiratory abnormalities, but a relationship between abnormalities of gastrointestinal and respiratory mechanics has not been adequately investigated. We sought an association between lower esophageal sphincter (LES) incompetence, gastroesophageal reflux (GER), and respiratory function abnormalities in 18 subjects (age 12 to 21 years) following repair of esophageal atresia (Vogt type 111B). In each subject, measurements were made of spirometry, lung volumes assessed by plethysmography, esophageal manometry recorded using a constantly infused fluid-filled trilumen catheter to assess LES pressure and esophageal motility, and esophageal pH monitoring to detect GER. Subjects were grouped according to the presence or absence of a radiologically supported diagnosis of pneumonia in the first 4 years of life. Lung volumes were mildly but significantly decreased in the "pneumonia" group compared with the "nonpneumonia" group. There was no association between abnormalities of respiratory function and abnormal LES pressure or the presence of GER. These data suggest that pneumonia in esophageal atresia infants is associated with mild long-term lung damage. LES dysfunction and GER do not appear to play a major role in this process.

    Agricultural activities such as land reclamation, crop production, pesticide and fertilizer application, irrigation and drainage will cause impact on the hydrological cycle and water quality of the catchment. In this study, the hydrological characteristics during storm runoff and long-term discharges of a complicated natural-artificial terraced paddy field catchment, which is composed of natural forest (73% of the area) and terraced paddy field (27% of the area), are compared with those of a natural forest catchment. According to the theory of the rational formula, peak discharge is given as: Qp=fp rtpA/3.6 (1) where, Qp is peak discharge, in m3/s; fp is the runoff coefficient, for the natural forest catchment and the complicated natural-artificial Catchment, fp=0.60 and 0.55, respectively; rtp is the average intensity of actual rainfall during tp, in mm/h; tp is concentration time, in min; A is the area of the catchment, in km2. According to literature, tp is given as: tp=CA0.22(re)-0.35 (2) where, C is a coefficient depending on land use, for the natural forest catchment and the complicated natural-artificial catchment and natural forest catchment, C=107 and 175, respectively; re is effective rainfall intensity and it is equal to the specific peak discharge of a storm, mm/h. From the comprehensive effects of runoff coefficient and concentration time on peak discharge, we find that the peak discharge of the complicated natural-artificial catchment is about 1.5 times as much as that of the natural forest catchment. Analyses of the recession limbs for various storms in the 2 catchments reveals that the storm runoff decreases with an exponential decay constant of 0.024 h-1 from several hours after rainfall to one or two days later, and then continues to decay with a decay constant of 0.011 h-1. By analysis of the relationship between percolation and duration of percolation in the 2 catchments we find that a linear relationship between the percolation and the duration

    2017-01-01

    Objective To investigate the factors affecting prognosis of extracorporeal shockwave therapy (ESWT) for chronic refractory Achilles tendinopathy (AT). Methods Thirty-six patients (48 consecutive feet) with chronic AT (>6 months) and who underwent ESWT for ‘poor’ or ‘fair’ grade in Roles-Maudsley Score (RMS) after unsuccessful conservative treatment were included in the present study. A maximum of 12 sessions of ESWT were conducted until treatment success: RMS reached ‘good’ or ‘excellent’. Termination of ESWT for no response, or ‘poor’ or ‘fair’ grade was regarded as treatment failure. Immediate outcome, long-term outcome (telephone interview after mean 26 months), and factors affecting treatment success were analyzed. Results Numeric Rating Scale was significantly decreased at immediate and long-term follow-up. Success rate was 71.1% and 90.3%, respectively. Univariate logistic regression identified that immediate treatment success was associated with retrocalcaneal enthesophyte on X-ray (odds ratio [OR], 0.06; 95% confidence interval [CI], 0.01–0.28), pretreatment abnormal ultrasonography echogenicity within Achilles tendon (OR, 18.89; 95% CI, 2.08–171.96), mean duration of ‘post-treatment soreness’ (OR, 0.55; 95% CI, 0.33–0.94), and duration of ‘post-treatment soreness after first ESWT’ (OR, 0.06; 95% CI, 0.01–0.34). The duration of ‘post-treatment soreness after first ESWT’ was found to be the only factor associated with long-term success (OR, 0.32; 95% CI, 0.10–0.99). Conclusion ESWT appears to be effective in achieving long-term success in chronic refractory AT. Immediate success was associated with absence of retrocalcaneal enthesophyte on X-ray, presence of pretreatment abnormal ultrasonography echogenicity, shorter mean duration of ‘post-treatment soreness’, and shorter duration of ‘post-treatment soreness after first ESWT’. The shorter duration of ‘post-treatment soreness after first ESWT’ was

    Antidepressants are one of the most commonly prescribed drugs in primary care. The rise in use is mostly due to an increasing number of long-term users of antidepressants (LTU AD). Little is known about the factors driving increased long-term use. We examined the socio-demographic, clinical factors and health service use characteristics associated with LTU AD to extend our understanding of the factors that may be driving the increase in antidepressant use. Cross-sectional analysis of 789 participants with probable depression (CES-D≥16) recruited from 30 randomly selected Australian general practices to take part in a ten-year cohort study about depression were surveyed about their antidepressant use. 165 (21.0%) participants reported <2 years of antidepressant use and 145 (18.4%) reported ≥2 years of antidepressant use. After adjusting for depression severity, LTU AD was associated with: single (OR 1.56, 95%CI 1.05-2.32) or recurrent episode of depression (3.44, 2.06-5.74); using SSRIs (3.85, 2.03-7.33), sedatives (2.04, 1.29-3.22), or antipsychotics (4.51, 1.67-12.17); functional limitations due to long-term illness (2.81, 1.55-5.08), poor/fair self-rated health (1.57, 1.14-2.15), inability to work (2.49, 1.37-4.53), benefits as main source of income (2.15, 1.33-3.49), GP visits longer than 20min (1.79, 1.17-2.73); rating GP visits as moderately to extremely helpful (2.71, 1.79-4.11), and more self-help practices (1.16, 1.09-1.23). All measures were self-report. Sample may not be representative of culturally different or adolescent populations. Cross-sectional design raises possibility of "confounding by indication". Long-term antidepressant use is relatively common in primary care. It occurs within the context of complex mental, physical and social morbidities. Whilst most long-term use is associated with a history of recurrent depression there remains a significant opportunity for treatment re-evaluation and timely discontinuation.

    The incidence of late graft complications such as para-anastomotic aneurysms, aortoenteric fistulas and graft infections following abdominal aortic aneurysm (AAA) repair is a major determinant of its overall benefit, yet most published reports of AAA repair have concentrated almost exclusively on the early postoperative mortality and morbidity. Accurate knowledge regarding the incidence of late complications is essential to making any decision regarding the operative vs nonoperative management of AAAs. A similar analysis must be applied to endovascular repair of AAAs before this technique is accepted as an alternative method of treating AAAs. In this article we review the current knowledge and understanding on the late results following aortic aneurysm repair.

    Peripheral nerve blockade is gaining popularity as an analgesic option for both upper or lower limb surgery. Published evidence supports the improved efficacy of regional techniques when compared to conventional opioid analgesia. The incidence of neurological deficit after surgery associated with peripheral nerve block is unclear. This paper reports on neurological outcomes occurring after 1065 consecutive peripheral nerve blocks over a one-year period from a single institution. All patients receiving peripheral nerve blocks for surgery were prospectively followed for up to 12 months to determine the incidence and probable cause of any persistent neurological deficit. Formal independent neurological review and testing was undertaken as indicated. Thirteen patients reported symptoms that warranted further investigation. A variety of probable causes were identified, with peripheral nerve block being implicated in two cases (one resolved at nine months and one remaining persistent). Overall incidence of block-related neuropathy was 0.22%. Persistent postoperative neuropathy is a rare but serious complication of surgery associated with peripheral nerve block. Formal follow-up of all such blocks is recommended to assess causality and allow for early intervention.

    Epiploic foramen entrapment (EFE) has been associated with a particularly poor post operative prognosis for equine colic cases, but the reasons for this are unknown. To identify variables associated with post operative survival following surgery for small intestinal disease; develop a model describing long-term post operative survival; and identify reasons for the poor prognosis associated with EFE. Data from 382 horses undergoing surgery were used to identify variables associated with survival. A multivariable Cox proportional hazards model for post operative survival was developed and model fit evaluated. The final model included the variables total plasma protein (TP) and packed cell volume (PCV) at admission, duration of surgery and the dichotomous variable relaparotomy (yes/no). Risk of death was positively associated with increasing PCV, but negatively associated with increasing TP (which decreased the probability of death). In a univariable model, EFE cases had a significantly higher death rate than other types of small intestinal disease (hazard ratio = 1.7, P = 0.035). Multivariable modelling indicated that some of the increased risk associated with EFE cases was due to lower TP values and longer duration of surgery. Preoperative TP is associated negatively with the risk of post operative death in horses recovering from small intestinal surgery. Other variables associated with the probability of survival are preoperative PCV, duration of surgery and relaparotomy. The increased post operative death rate of EFE cases can be explained in part by lower TP and longer surgery times of these cases. Total plasma protein may be not simply a measure of hydration status in small intestinal colic cases, but an important determinant of survival. Further investigation of this relationship is warranted. Our model for post operative survival highlights the importance of preoperative TP, PCV and duration of surgery as prognostic indicators. This information should allow a

    Obesity is associated with 2 closely related respiratory diseases: obesity hypoventilation syndrome (OHS) and obstructive sleep apnea-hypopnea syndrome (OSAHS). It has been shown that noninvasive ventilation during sleep produces clinical and functional improvement in these patients. The long-term survival rate with this treatment, and the difference in clinical progress in OHS patients with and without OSAHS are analyzed. Longitudinal, observational study with a cohort of patients diagnosed with OHS, included in a home ventilation program over a period of 12 years, divided into 2 groups: pure OHS and OSAHS-associated OHS. Bi-level positive airway pressure ventilation was administered. During the follow-up period, symptoms, exacerbations and hospitalizations, blood gas tests and pulmonary function tests, and survival rates were monitored and compared. Eighty-three patients were eligible for analysis, 60 women (72.3%) and 23 men (27.7%), with a mean survival time of 8.47 years. Fifty patients (60.2%) were included in the group without OSAHS (OHS) and 33 (39.8%) in the OSAHS-associated OHS group (OHS-OSAHS). PaCO₂ in the OHS group was significantly higher than in the OHS-OSAHS group (P<.01). OHS patients also had a higher hospitalization rate (P<.05). There was a significant improvement in both groups in FEV₁ and FVC, and no differences between groups in PaCO₂ and PaO₂ values. There were no differences in mortality between the 2 groups, but low FVC values were predictive of mortality. The use of mechanical ventilation in patients with OHS, with or without OSAHS, is an effective treatment for the correction of blood gases and functional alterations and can achieve prolonged survival rates.

    Background Verbal and physical aggressive behaviours are among the most disturbing and distressing behaviours displayed by older patients in long-term care facilities. Aggressive behaviour (AB) is often the reason for using physical or chemical restraints with nursing home residents and is a major concern for caregivers. AB is associated with increased health care costs due to staff turnover and absenteeism. Methods The goals of this secondary analysis of a cross-sectional study are to determine the prevalence of verbal and physical aggressive behaviours and to identify associated factors among older adults in long-term care facilities in the Quebec City area (n = 2 332). Results The same percentage of older adults displayed physical aggressive behaviour (21.2%) or verbal aggressive behaviour (21.5%), whereas 11.2% displayed both types of aggressive behaviour. Factors associated with aggressive behaviour (both verbal and physical) were male gender, neuroleptic drug use, mild and severe cognitive impairment, insomnia, psychological distress, and physical restraints. Factors associated with physical aggressive behaviour were older age, male gender, neuroleptic drug use, mild or severe cognitive impairment, insomnia and psychological distress. Finally, factors associated with verbal aggressive behaviour were benzodiazepine and neuroleptic drug use, functional dependency, mild or severe cognitive impairment and insomnia. Conclusion Cognitive impairment severity is the most significant predisposing factor for aggressive behaviour among older adults in long-term care facilities in the Quebec City area. Physical and chemical restraints were also significantly associated with AB. Based on these results, we suggest that caregivers should provide care to older adults with AB using approaches such as the progressively lowered stress threshold model and reactance theory which stress the importance of paying attention to the severity of cognitive impairment and avoiding the use

    Our aim in this study was to describe the long-term survival of the native hip joint after open reduction and internal fixation of a displaced fracture of the acetabulum. We also present long-term clinical outcomes and risk factors associated with a poor outcome. A total of 285 patients underwent surgery for a displaced acetabular fracture between 1993 and 2005. For the survival analysis 253 were included, there were 197 men and 56 women with a mean age of 42 years (12 to 78). The mean follow-up of 11 years (1 to 20) was identified from our pelvic fracture registry. There were 99 elementary and 154 associated fracture types. For the long-term clinical follow-up, 192 patients with complete data were included. Their mean age was 40 years (13 to 78) with a mean follow-up of 12 years (5 to 20). Injury to the femoral head and acetabular impaction were assessed with CT scans and patients with an ipsilateral fracture of the femoral head were excluded. A total of 36 patients underwent total hip arthroplasty (THA). The overall ten-year survival of the hip joint was 86% (95% confidence interval (CI) 81% to 90%) and the 20-year survival was 82% (95% CI 76% to 87%). Injury to the femoral head and acetabular impaction were the strongest predictors of failure, with the long-term survival rate falling towards 50% in these patients. The survival fell to 0% at three years when both these risk factors were present in patients aged > 60 years. The long-term survival of the native hip joint after acetabular fractures was good, but the presence of injury to the femoral head and acetabular impaction proved to be strong predictors of failure, especially in patients aged > 60 years. These patients may be better treated with a combination of open reduction and internal fixation and primary arthroplasty.

    A multicenter survey was conducted regarding the safety and outcome of living liver donors in Asia. Five Asian liver transplant centers reported a total of 1,508 living donor liver transplantations (LDLT) performed between January 1990 and December 2001. The recipients consisted of 766 adults and 742 children. The graft types were left lateral or extended left lateral segment in 605, left lobe in 334, right lobe or right lateral sector in 561, and not classified in eight cases. The donor blood loss was less than 1,000 mL in 94.1% of the cases, and 0.53% of the donors received banked blood transfusion. The overall donor complication rate was 15.8%, and 1.1% of donors underwent reoperation. The complication rate was higher in right lobe (28%) than in left lateral segment (9.3%) or left lobe (7.5%) donors. In particular, right lobe donors had more serious complications such as cholestasis (7.3%), bile leakage (6.1%), biliary stricture (1.1%), portal vein thrombosis (0.5%), intra-abdominal bleeding (0.5%), and pulmonary embolism (0.5%). There was no hospital mortality, but there was one late donor death 3 years after operation. Long-term follow-up beyond 3 months was available in 15.1% of the donors only. The data from the multicenter study set the standard for the safety of living liver donors in high-volume liver transplant centers in Asia and provide further justification for the continued application of LDLT in the face of the critical organ shortage in Asia. The long-term outcome of liver donation, however, remains unknown, and transplant centers should continue their follow-up of donors.

    Morbidly obese patients are affected by gastroesophageal reflux disease (GERD) and hiatal hernia (HH) more frequently than lean patients. Because of conflicting results, the indication to sleeve gastrectomy (SG) in patients with GERD is still debated. To evaluate the incidence of GERD on the basis of clinical, endoscopic, and histologic data in patients undergoing SG. University hospital, Rome, Italy. From July 2007 to January 2010, 162 patients underwent primary SG. Preoperatively all patients underwent visual analogue scale (VAS) evaluation of GERD symptoms, proton pump inhibitors (PPIs) consumption recording, and esophagogastroduodenoscopy (EGD). Stomach resection started 6 cm from pylorus on a 48Fr bougie. Staple line was reinforced by an oversewing suture. A postoperative clinical control with VAS evaluation, PPI consumption, and EGD was proposed to all patients. Three patients were excluded because of the occurrence of major postoperative complications. A total of 110 patients accepted to take part in the study (follow-up rate: 69.1%). At a mean 58 months of follow-up, incidence of GERD symptoms, VAS mean score, and PPI intake significantly increased compared with preoperative values (68.1% versus 33.6%: P<.0001; 3 versus 1.8: P = .018; 57.2% versus 19.1%: P<.0001) At EGD, an upward migration of the "Z" line and a biliary-like esophageal reflux was found in 73.6% and 74.5% of cases, respectively. A significant increase in the incidence and in the severity of erosive esophagitis (EE) was evidenced, whereas nondysplastic Barrett's esophagus (BE) was newly diagnosed in 19 patients (17.2%). No significant correlations were found between GERD symptoms and endoscopic findings. In the present series the incidence of EE and of BE in SG patients was considerably higher than that reported in the current literature, and it was not related to GERD symptoms. Endoscopic surveillance after SG should be advocated irrespective of the presence of GERD symptoms. Copyright

    Atraumatic distal clavicular osteolysis (DCO) has been described in adult male weightlifters. Our purpose was to investigate the frequency, magnetic resonance imaging (MRI) characteristics, risk factors, and long-term sequelae of DCO in young patients. Individuals with atraumatic DCO were identified in a retrospective review of 1,432 consecutive MRI shoulder reports in patients between 13 and 19 years of age. MRI findings of DCO, association with athletic activity, short-term clinical outcome after 3-6 months, and long-term clinical and MRI outcome after 2 years were analyzed. A pre-MRI questionnaire assessed the patients' athletic history including overhead activity and weightlifting. At a mean age of 15.9 years, 6.5 % (93/1432) of patients had atraumatic DCO, and 24 % were females. The combination of an overhead sport (basketball, volleyball, tennis, swimming) and supplemental weight training was a risk factor for DCO (odds ratio = 38, p = 0.01). Ninety-three percent of patients responded to conservative therapy. On follow-up imaging, 71 % of DCO patients had acromioclavicular (AC) joint osteoarthritis (vs. 35 % in controls, p = 0.006); 79 % had flattening of the distal clavicle and interval widening of the AC joint to a mean of 5.0 mm (compared to 2.4 mm in controls, p < 0.001). Severity of DCO edema was associated with pain (p < 0.02) at initial presentation and with AC joint osteoarthritis (p = 0.004) on follow-up. In athletic teenagers, the combination of weightlifting and overhead activity is a risk factor for atraumatic DCO, and females are affected in 24 %. Long-term sequelae include widening of the AC joint and AC joint osteoarthritis.

    Initiation of a long-term improvement of cardiac risk factors is one of the major aims of a cardiac rehabilitation/secondary prevention programme. The Health Guide collected data in terms of cardiac risk factors: blood pressure, resting pulse, total cholesterol, LDL cholesterol, body weight, physical activity and number of cigarettes at admission and discharge after a stationary rehabilitation programme and every 3 months. After 12 months the Health Guides were returned. In the prospective study 2664 patients (71.8% men, age: MV = 62.94 years, SD = 9.96; 28% women, MV = 67.59 years, SD = 9.53) with coronary heart disease (CHD) were included. All cardiac risk factors documented by the Health Guide improved during the cardiac rehabilitation programme. After one year, risk factors were significantly lower than at admission, apart from total cholesterol. The individual goal in terms of body weight and LDL cholesterol was partially achieved after the rehabilitation programme and maintained after one year. In the investigation years, 2004-2007, the cholesterol and blood pressure were significantly lower than in the years 2000-2003. The use of a Health Guide resulted in an improved long-term effect of a cardiac rehabilitation/secondary prevention programme. It is a simple and cheap intervention and can help in the guidance of the patients.

    With improvements in the treatment of children with organic acidaemias (OA), the number surviving to adulthood is increasing. To plan appropriate services for their care it is important to know what their needs are. To describe the clinical and social problems affecting adult patients with OA. We reviewed the medical records of 15 adult patients diagnosed with OA. Social attainment (housing, schooling and occupation) was analysed. Nutritional status was evaluated by body mass index (BMI) and laboratory studies. Neurological and visceral complications were noted. Cognitive outcome was evaluated by psychometric testing and/or educational attainment. Seven had methylmalonic acidaemia (MMA), 4 isovaleric acidaemia (IVA) and 4 propionic acidaemia (PA). Ten were female, and median age was 23.5 years (range 18-48). All but three had late-onset disease. Two patients became pregnant during follow up. Four patients had obtained university degrees and were working. Three-quarters of the patients required some kind of social support. All had a good nutritional status. Height was normal in IVA and 3 PA patients. Osteoporosis was present in 2 out of 8 patients assessed. A variety of neurocognitive or visceral complications were seen in two-thirds of the patients. Metabolic decompensations were unusual. The approach to adult patients with OA has to be multidisciplinary, with the clinician and dietician as the core of the team, but with the collaboration of clinical nurses specialists, social workers and other specialist services and the support of a biochemical and molecular laboratory.

    Background. Long-term outcomes (mortality and health-related quality of life) of sepsis have risen as important indicators for health care. Pulmonary infection and abdominal infection are the leading causes of sepsis. However, few researches about long-term outcomes focused on the origin of sepsis. Here we aim to study the clinical differences between pulmonary-sepsis and abdominal-sepsis and to investigate whether different infection foci were associated with long-term outcomes. Methods. Patients who survived after hospital discharge were followed up by telephone interview. Quality of life (QoL) was assessed using the EuroQol 5-dimension (EQ5D) questionnaire. Results. Four hundred and eighty-three sepsis patients were included, 272 (56.3%) had pulmonary-sepsis, and 180 (37.3%) had abdominal-sepsis. The overall ICU and one-year mortality rates of the cohort were 17.8% and 36.1%, respectively. Compared with abdominal-sepsis, pulmonary-sepsis patients had older age, higher APACHE II, higher ICU mortality (31.7% versus 12.6%), and one-year mortality (45.4% versus 24.4%), together with worse QoL. Age, septic shock, acute renal failure, fungus infection, anion gap, and pulmonary infection were predictors for one-year mortality and pulmonary infection was a risk factor for poor QoL. Conclusions. Pulmonary-sepsis showed worse outcome than abdominal-sepsis. Pulmonary infection is a risk factor for one-year mortality and QoL after sepsis. PMID:28050557

    This study was a retrospective analysis of patients with CLI who underwent infrapopliteal percutaneous transluminal angioplasty (PTA). The main goal was to evaluate clinical and morphological factors that influence the clinical outcome of PTA in long-term follow-up. A total of 1,445 PTA procedures were performed in 1,268 patients. Main indications for PTA included gangrene, nonhealing ulcers, or rest pain. The mean number of treated arteries was 1.77 artery/limb, and the majority of lesions were type TASC D. The technical success rate of PTA was 89% of intended-to-treat arteries. The main criterion of clinical success was functional limb salvage (LS). One-year follow-up involved 1,069 limbs. Primary and secondary 1-year LS rates were 76.1 and 84.4%, respectively. The effect of clinical and morphological parameters on the 1-year LS was that the only associated disease with an adverse effect on LS rate was DM combined with dialysis. Regarding limb preprocedural status, gangrene was clearly a negative predictor. The most important factor affecting LS was the number of patent arteries post-PTA: patients with 0, 1, 2, and 3 patent arteries had 1-year primary LS rates of 56.4, 73.1, 80.4, and 83%, respectively. Long-term follow-up of LS rates demonstrated secondary LS rates of 84.4, 78.8, and 73.3% at 1, 5, and 10 years. Every effort should be made to perform PTA for as many arteries as possible, even if TASC D type, to improve clinical outcome. Our study shows that repeat PTA is capable of keeping the long-term LS rate close to 75%.

    To evaluate survival rate and complications after jejunocecostomy in horses with colic and to compare outcomes after hand-sewn versus stapled side-to-side jejunocecostomy. Retrospective cohort study. 32 horses. Information was retrieved from medical records and through telephone calls on horses that had a hand-sewn or stapled side-to-side jejunocecostomy for treatment of colic, which was performed by or under the supervision of the same surgeon. Kaplan-Meier life table analysis was used to compare survival times and rates between horses that underwent a hand-sewn or stapled side-to-side anastomosis. 32 horses met inclusion criteria; 22 underwent a hand-sewn anastomosis, and 10 underwent a stapled anastomosis. Horses in the stapled group had a significantly greater prevalence of postoperative colic and combined postoperative colic and reflux than horses in the hand-sewn group. In the hand-sewn group, repeated celiotomy was performed within the same hospitalization period for 3 of 22 horses; in the stapled group, 4 of 10 horses had repeated celiotomies. Hospital discharge rates (ie, short-term survival rates) were similar between horses in the hand-sewn group (20/22 horses) and those in the stapled group (9/10 horses). Long-term survival rates were similar for both groups, ranging from 5 to 126 months. Short- and long-term results justify use of jejunocecostomy in horses. Despite similar survival rates between groups, horses that underwent a stapled anastomosis had significantly greater prevalences of postoperative complications than horses that underwent a hand-sewn anastomosis, suggesting that horses were sensitive to minor differences in anastomosis techniques.

    Introduction Cervical spine pathologies are common in Down syndrome (DS) patients. Cervical pathologies may cause cord compression and neurologic deterioration if left untreated. Complication rates of 73-100% have been reported in DS patients after cervical spine surgery in historical studies. This study reports updated perioperative complications rates and long-term outcome in patients with DS undergoing cervical spine surgery. Methods Retrospective review of patients with DS who have undergone cervical spine surgery from 1998 to 2011 (≥ 24 months of follow-up) was undertaken. Series of 17 adults with preoperative diagnoses that included atlantoaxial instability, stenosis, spondylosis, or cervical spondylolisthesis were evaluated. Nine patients received recombinant human bone morphogenetic protein-2 (rhBMP-2). Neurologic and ambulatory status was evaluated at regular intervals included pre- and postoperative imaging, range of motion evaluation, strength/neurologic testing, ambulation observation, and patient and caretaker pain reporting. Results A total of 20 surgical procedures were performed in 17 patients. Average follow-up was 78.7 months (range: 25-156 months). Overall, 37 complications were observed including pneumonia, respiratory distress, reintubation, dysphagia, deep venous thrombosis, sepsis, wound infection, dehiscence, neurologic complications, loss of reduction (LOR), pseudarthrosis, and hardware failure. Postoperative pneumonia was most common (23.5%). Three patients developed pseudarthrosis (all in the rhBMP-2 group); three demonstrated LOR. Neurologic complications (N = 3) included spasticity, loss of ambulation, and postoperative weakness with myelomalacia. Two were transient. Respiratory complications in the rhBMP-2 group were the most common (N = 3). The anterior approach resulted in a higher likelihood of complications than the posterior (p = 0.032). Conclusions Current techniques may improve pseudarthrosis (p = 0

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

    Neurotrophins are critically involved in developmental processes such as neuronal cell survival, growth, and differentiation, as well as in adult synaptic plasticity contributing to learning and memory. Our previous studies examining neurotrophins and memory formation in Aplysia showed that a TrkB ligand is required for MAPK activation, long-term synaptic facilitation (LTF), and long-term memory (LTM) for sensitization. These studies indicate that neurotrophin-like molecules in Aplysia can act as key elements in a functionally conserved TrkB signaling pathway. Here we report that we have cloned and characterized a novel neurotrophic factor, Aplysia cysteine-rich neurotrophic factor (apCRNF), which shares classical structural and functional characteristics with mammalian neurotrophins. We show that apCRNF (1) is highly enriched in the CNS, (2) enhances neurite elongation and branching, (3) interacts with mammalian TrkB and p75(NTR), (4) is released from Aplysia CNS in an activity-dependent fashion, (5) facilitates MAPK activation in a tyrosine kinase dependent manner in response to sensitizing stimuli, and (6) facilitates the induction of LTF. These results show that apCRNF is a native neurotrophic factor in Aplysia that can engage the molecular and synaptic mechanisms underlying memory formation.

    Our objective was to identify the factors adversely affecting long-term patency after percutaneous transluminal angioplasty (PTA) for hemodialysis Brescia-Cimino arteriovenous fistulas. Between November 1995 and March 2000, 91 PTA procedures were performed on 50 patients with 57 Brescia-Cimino fistulas. A retrospective study based on the chart review was performed. The initial technical success rate for all procedures and the primary and secondary patency rates for all fistulas were calculated. Regarding fistulas successfully maintained by the primary PTA, the primary and secondary patency rates were compared using the Kaplan-Meier method between two patient groups. They were classified on the basis of several factors, including age (older, over 70 years, and younger group), age of the fistulas (older, over 6 months, and younger group), with or without diabetes mellitus (DM), solitary or multiple lesions, long or short segment lesion, stenosis or occlusion, and with or without arterial and/or anastomotic lesions. Initial technical success rates for all procedures and fistulas were 91.2 and 89.5%, respectively. Cumulative primary and secondary patency rates at 1 year were 47.3 and 67.3%, respectively. In the comparative study, the secondary patency rate for the older group was lower than that of the younger group with statistical significance ( p=0.029). The higher age is the only factor that reduces the long-term patency rate after PTA.

  10. Long Term Outcomes after Pediatric Liver Transplantation

    2013-01-01

    Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle. PMID:24511516

    In this study we tested whether HIV-1 replication could be inhibited by stable RNAi-mediated knockdown of cellular co-factors. Cell lines capable of expressing shRNAs against 30 candidate co-factors implicated at different steps of the viral replication cycle were generated and analyzed for effects on cell viability and inhibition of HIV-1 replication. For half of these candidate co-factors we obtained knockdown cell lines that are less susceptible to virus replication. For three co-factors (ALIX, ATG16 and TRBP) the cell lines were resistant to HIV-1 replication for up to 2 months. With these cells we could test the hypothesis that HIV-1 is not able to escape from RNAi-mediated suppression of cellular co-factors, which was indeed not detected.

    To examine the long-term effects of type 1 diabetes treatment, metabolic control, and complications on health-related quality of life (HRQOL). A total of 1,441 participants, initially 13-39 years of age, were followed for an average of 23.5 years as part of the Diabetes Control and Complications Trial (DCCT) and the Epidemiology of Diabetes Interventions and Complications (EDIC) follow-up study. The Diabetes Quality-of-Life questionnaire (DQOL) was administered annually during DCCT and every other year during EDIC. Biomedical data, including HbA1c levels, exposure to severe hypoglycemia, intercurrent psychiatric events, and development of diabetes complications were collected at regular intervals throughout the follow-up. Mean total DQOL scores were not significantly different between the former DCCT intensive and conventional treatment groups (DCCT baseline, 78±8 vs. 78±9; EDIC year 17, 75±11 vs. 74±11). Over the course of the study, a drop of ≥5 points in DQOL score from DCCT baseline maintained on two successive visits occurred in 755 individuals and was associated with increased HbA1c, albumin excretion rate, mean blood pressure, BMI, and occurrence of hypoglycemic events requiring assistance. Lower DQOL scores after 23.5 years of follow-up were associated with prior development of retinopathy (P=0.0196), nephropathy (P=0.0019), and neuropathy (P<0.0001) as well as self-reported chest pain (P=0.0004), decreased vision in both eyes (P=0.0005), painful paresthesias (P<0.0001), recurrent urinary incontinence (P=0.0001), erectile dysfunction (P<0.0001), and history of psychiatric events (P<0.0001). Among DCCT/EDIC participants, worsening metabolic control, serious diabetes complications and their associated symptoms, and development of psychiatric conditions led to decreased HRQOL.

  13. The Preeminence of Early Life Trauma as a Risk Factor for Worsened Long-Term Health Outcomes in Women.

    2015-11-01

    Early life trauma (ELT) comprises an array of disturbingly common distressing experiences between conception and the beginning of adulthood with numerous and significant potential long-term, even transgenerational, health consequences of great public health concern, including depression, cardiovascular disease, and other psychiatric and medical disorders, and neurobiological, psychological, and behavioral effects which are sufficiently robust to confound many types of biomedical research. The impact of ELT on a woman's health trajectory appears to vary with the specific characteristics of the ELT (e.g., type, number of different types, severity, and timing), the individual (e.g., age, genetics, epigenetics, personality, and cognitive factors), and the individual's environment (e.g., level of social support and ongoing stressors) and to be mediated to a significant extent by persistent changes in a number of biological systems, dysregulation of those governing the stress response chief among them. Growing knowledge of the risk factors and pathophysiological mechanisms by which ELT confers diathesis to various poor health outcomes and the unique treatment-response profiles of women with ELT will lead to much needed improvements in prevention, diagnostic, and therapeutic efforts, including more effective psychotherapy and pharmacotherapy approaches, hopefully making strides toward improvements in the lives of women everywhere and ending countless cycles of intergenerational trauma-associated pathology. This article attempts to broadly summarize the current state of knowledge about the long-term sequelae of ELT for women's health.

    We developed and validated an empirical model for estimating chlorophyll a concentrations (Chla) in Lake Taihu to generate a long-term Chla and algal bloom area time series from MODIS-Aqua observations for 2003 to 2013. Then, based on the long-term time series data, we quantified the responses of cyanobacterial dynamics to nutrient enrichment and climatic conditions. Chla showed substantial spatial and temporal variability. In addition, the annual mean cyanobacterial surface bloom area exhibited an increasing trend across the entire lake from 2003 to 2013, with the exception of 2006 and 2007. High air temperature and phosphorus levels in the spring can prompt cyanobacterial growth, and low wind speeds and low atmospheric pressure levels favor cyanobacterial surface bloom formation. The sensitivity of cyanobacterial dynamics to climatic conditions was found to vary by region. Our results indicate that temperature is the most important factor controlling Chla inter-annual variability followed by phosphorus and that air pressure is the most important factor controlling cyanobacterial surface bloom formation followed by wind speeds in Lake Taihu.

    Early retinal vascular changes in the development of diabetic retinopathy (DR) include capillary basal lamina (BL) thickening, pericyte loss and the development of acellular capillaries. Expression of the CCN (connective tissue growth factor/cysteine-rich 61/nephroblastoma overexpressed) family member CCN2 or connective tissue growth factor (CTGF), a potent inducer of the expression of BL components, is upregulated early in diabetes. Diabetic mice lacking one functional CTGF allele (CTGF⁺/⁻) do not show this BL thickening. As early events in DR may be interrelated, we hypothesized that CTGF plays a role in the pathological changes of retinal capillaries other than BL thickening. We studied the effects of long-term (6-8 months) streptozotocin-induced diabetes on retinal capillary BL thickness, numbers of pericytes and the development of acellular capillaries in wild type and CTGF⁺/⁻ mice. Our results show that an absence of BL thickening of retinal capillaries in long-term diabetic CTGF⁺/⁻ mice is associated with reduced pericyte dropout and reduced formation of acellular capillaries. We conclude that CTGF is involved in structural retinal vascular changes in diabetic rodents. Inhibition of CTGF in the eye may therefore be protective against the development of DR.

    Earlier studies dealing with sarcopenia were conducted among community-living or hospitalized older adults; however, to date, study focusing on older adults living in institutions providing long-term care is lacking. The aim of this study was to describe the prevalence of sarcopenia and its associations with lifestyle and health factors among older people living in institutions providing long-term care. Two hundred five individuals participated in the study. Sarcopenia was diagnosed based on muscle mass, muscle strength and functional performance. The independent variables were functional mobility, protein intake, smoking, current physical activity, and physical activity when middle-aged, multimorbidity, and falls in the previous year. Univariate models and a multivariate model were used to assess associations. In total 73 participants had sarcopenia. Sarcopenia was associated with smoking, multimorbidity, physically active lifestyle when middle aged, and functional mobility. This study showed that lifestyle factors and health condition have important roles in the prevalence of sarcopenia. Orv. Hetil., 2016, 157(46), 1847-1853.

    Objectives. We examined risk factors for long-term homelessness among newly homeless men and women who were admitted to New York City shelters in 2001 and 2002. Methods. Interviews were conducted with 377 study participants upon entry into the shelter and at 6-month intervals for 18 months. Standardized assessments of psychiatric diagnosis, symptoms, and coping skills; social and family history; and service use were analyzed. Kaplan—Meier survival analysis and Cox regression were used to examine the association between baseline assessments and duration of homelessness. Results. Eighty-one percent of participants returned to community housing during the follow-up period; the median duration of homelessness was 190 days. Kaplan—Meier survival analysis showed that a shorter duration of homelessness was associated with younger age, current or recent employment, earned income, good coping skills, adequate family support, absence of a substance abuse treatment history, and absence of an arrest history. Cox regression showed that older age group P<.05) and arrest history (P<.01) were the strongest predictors of a longer duration of homelessness. Conclusions. Identification of risk factors for long-term homelessness can guide efforts to reduce lengths of stay in homeless shelters and to develop new preventive interventions. PMID:16131638

     Although many intrinsic and extrinsic risk factors are involved, pressure is the most important factor in the development of pressure ulcers. The elderly are more susceptible to the development of these skin lesions as a result of changes associated with the aging process. The aim of this study was to identify the risk factors for pressure ulcers in the elderly living in long-term institutions. An analytic cross-sectional study of 40 patients age 60 years and older with pressure ulcers was conducted in six long-term institutions for the elderly (LTIE) in the West Side of São Paulo, Brazil. The present study evaluates pressure ulcers and their associated risk factors. Statistical analysis was performed using Pearson's chi-square test, Student's t-test, and Fisher's exact test. A statistically significant association between the risk factors evaluated in this study and the development of pressure ulcers in the sample was not found. According to the Braden scale, 67.5% of the patients were at high risk for pressure ulcer development. Fifty-one pressure ulcers were detected, with the majority (56.2%) being located in the sacral region. In the present study, more than 50% of the patients had low sensory perception, mobility, nutrition, and friction and shear subscales scores. The most prevalent risk factors were advanced age (mean, 83.8 years), length of stay that exceeded 31 months, white skin, neuromotor and skeletal muscle disorders, urinary and fecal incontinence, and continuous use of sedatives, analgesics, and hypotensives. The knowledge of risk factors is essential for healthcare professionals in planning effective prevention programs that target the elderly living in LTIE.

    This cross-sectional study aimed to evaluate the prevalence of depressive disorders and factors associated in long-term cancer survivors. A total of 702 long-term cancer survivors over 5-years in remission were recruited in a university-affiliated tertiary hospital in Korea. Self-report using the Patient Health Questionnaire-2 and the Fatigue Severity Scale assessed depression and fatigue, respectively. Demographic characteristics, cancer-related clinical characteristics, comorbidity, health behaviors, and physical symptoms were assessed through the review of medical records or a structured self-administered questionnaire. We identified 26.1% of patients who had a depressed mood or displayed a loss of interest. The most prevalent primary site of cancer was the stomach (65.2%), followed by lung, breast, colorectal, and thyroid cancer. We also found that 5.7% of subjects experienced double or triple primary cancers. Larger proportion among depressive group (89.1%) complained at least one physical problem than among non-depressive group (53.2%). Physical symptoms including sleep problems, dry mouth, indigestion, pain, decreased appetite, and febrile sense were more frequent in the depressive group than in the non-depressive group. The Fatigue Severity Scale scores were higher in the depressive group than in the non-depressive group (P<0.001). Multiple logistic regression analysis showed that the highest tertile level of fatigue (odds ratio, 7.31; 95% confidence interval, 3.81-14.02) was associated with the increased risk of depression. These findings suggest that careful concern about depression is necessary in long-term cancer survivors. Fatigue may be a surrogate sign for depression, and warrants further evaluation.

    The goal of this mixed-methods study was to characterize the perceptions of multi-cultural long-term care nurses about patient dignity at the end-of-life (EOL). The study was conducted in a large, urban long-term care (LTC) facility. The participants were forty-five long-term care nurses and 26 terminally ill nursing home patients. Nurses completed an open-ended interview about their perceptions of the concept of dying with dignity and the data were analyzed using grounded theory methods. Main themes identified as promoting patient dignity at the EOL included treating them with respect, helping them prepare for their EOL, promoting shared decision making and providing high quality tenor of care. The nurses’ cultural and religious backgrounds influenced their perceptions of what constitutes dignity-conserving care. Foreign-born nurses stressed the need for end-of-life rituals but this was strikingly absent in the statements of US-born nurses. Foreign-born Catholic nurses stated that the dying experience should not be altered using analgesics to relieve suffering or by attempts to hasten death by forgoing curative therapy or by other means. Both nurses and terminally ill patients completed the Dignity Card-sort Tool (DCT). A comparison of the LTC nurses cohort to the terminally ill patient responses on the DCT revealed that the nurses felt that patient dignity was eroded when her/his wishes were not carried out and when s/he is treated without respect. In contrast, dying LTC patients felt that poor medical care and loss of ability to choose care options to be the most important factors leading to erosion of dignity. PMID:23496266

Main themes identified as promoting resident dignity at the EOL included treating them with respect, helping them prepare for the EOL, promoting shared decision-making, and providing high-quality care. The nurses’ cultural and religious backgrounds influenced their perceptions of what constitutes dignity-conserving care. Foreign-born nurses stressed the need for EOL rituals, but this was strikingly absent in the statements of U.S.-born nurses. Foreign-born Catholic nurses stated that the dying experience should not be altered using analgesics to relieve suffering or by attempts to hasten death by forgoing curative therapy or by other means. Nurses and terminally ill individuals completed the Dignity Card-sort Tool (DCT). A comparison of the DCT responses of the LTC nurses cohort with those of the terminally ill participants revealed that the nurses felt patient dignity was eroded when patient wishes were not followed and when they were treated without respect. In contrast, dying LTC residents felt that poor medical care and loss of ability to choose care options were the most important factors leading to erosion of dignity.

    Among all the rivers flowing into the Arctic Ocean, the three great Siberian rivers; Lena, Yenisei and Ob, are the three largest in terms of discharge (R), and are sources of freshwater, organic matter and heat into the ocean. While long-term variation and trend of the Rs have been examined in a lot of previous studies, causes of the R variations are still unclear. A previous study indicated the negative correlation between the Lena and Ob Rs during the 1980s to mid-1990s and it was affected by an east-west seesaw pattern of atmospheric circulation over Siberia. Our analysis indicated that 15-year running correlations between observed Rs of the Lena and Ob becomes weak after the mid-1990s and it was positive in mid-1950s to 1960s. The similar relationships were seen in precipitation (P) over the two basins. As in the observed Rs, more long-term record of reconstructed Rs of the Lena and Ob based on the tree-ring showed positive, negative and weak correlations in each of the epochs during the past two centuries. Interestingly, the correlations of the reconstructed Rs tend to be distributed on the negative side. These negative correlations were associated with the east-west seesaw pattern, as in the previous study. In addition, the correlations of Ps over eastern and western Siberia in an atmospheric general circulation model (AGCM) control simulation were distributed on more negative side compared to those in the CMIP3 multi-coupled models' simulations. The results of the AGCM and CMIP3 models reveal that the seesaw pattern frequently appears as an atmospheric internal variability over Siberia. Therefore, our results indicated that the east-west seesaw pattern as an atmospheric internal variability is a key factor controlling the long-term variation of water cycles in Siberia region.

    Intrastriatal injection of mesencephalic astrocyte-derived neurotrophic factor (MANF) protein has been shown to provide neuroprotective and neurorestorative effects in a 6-hydroxydopamine (6-OHDA) - lesioned rat model of Parkinson's disease. Here, we used an adeno-associated virus serotype 9 (AAV9) vector to deliver the human MANF (hMANF) gene into the rat striatum 10days after a 6-OHDA lesion to examine long-term effects of hMANF on nigral dopaminergic neurons and mechanisms underlying MANF neuroprotection. Intrastriatal injection of AAV9-hMANF vectors led to a robust and widespread expression of the hMANF gene in the injected striatum up to 24weeks. Increased levels of hMANF protein were also detected in the ipsilateral substantia nigra. The hMANF gene transfer promoted the survival of nigral dopaminergic neurons, regeneration of striatal dopaminergic fibers and an upregulation of striatal dopamine levels, resulting in a long-term improvement of rotational behavior up to 16weeks after viral injections. By using SH-SY5Y cells, we found that intra- and extracellular application of MANF protected cells against 6-OHDA-induced toxicity via inhibiting the endoplasmic reticulum stress and activating the PI3K/Akt/mTOR pathway. Our results suggest that AAV9-mediated hMANF gene delivery into the striatum exerts long-term neuroprotective and neuroregenerative effects on the nigrostriatal dopaminergic system in parkinsonian rats, and provide insights into mechanisms responsible for MANF neuroprotection.

    This article examines the factors related to an individual's decision to purchase a given amount of long-term care insurance coverage. DATA SOURCE AND STUDY SETTING: Primary data analyses were conducted on an estimation sample of 6,545 individuals who had purchased long-term care (LTC) insurance policies in late 1990 and early 1991, and 1,248 individuals who had been approached by agents but chose not to buy such insurance. Companies contributing the two samples represented 45 percent of total sales during the study year. A two-stage logit-OLS (ordinary least squares) choice-based sampling model was used to examine the relationship between the expected value of purchased coverage and explanatory variables that included: demographic traits, attitudes, risk premium, nursing home bed supply, and Medicaid program configurations. Mail surveys were used to collect information about individuals' reasons for purchase, attitudes about long-term care, and demographic characteristics. Through an identification code, information on the policy designs chosen by these individuals was linked to each of the returned mail surveys. The response rate to the survey was about 60 percent. The model explains about 47 percent of the variance in the dependent variable-expected value of policy coverage. Important variables negatively associated with the dependent variable include advancing age, being married, and having less than a college education. Variables positively related include being male, having more income, and having increasing expected LTC costs. Medicaid program configuration also influences the level of benefits purchased: state reimbursement rates and the presence of comprehensive estate recovery programs are both positively related to the expected value of purchased benefits. Finally, as the difference between the premium charged and the actuarially fair premium increases, individuals buy less coverage. An important finding with implications for policymakers is that changes

    The BESTCapsule will maintain appropriate biological specimens for decades or centuries at cryogenic temperatures in the living state. Maintenance at temperatures below {approximately} {minus}140 C is not a problem. No ordinary chemical reactions in aqueous solutions can occur. The only source of damage will be the slow accumulation of physical damage to DNA from background ionizing radiation. But this source of damage should not become serious in less than a millennium. Rather, the main problem in cryopreservation is to devise procedures for cooling the biological specimens to {minus}196 C and returning them to normal temperatures without inflicting lethal injury. Regardless of the cell type, there are certain encompassing biophysical factors and constraints that determine whether they will survive or die during freezing and thawing. Superimposed on these may be special biological factors that apply to specific cell types. This paper will emphasize the former and give illustrative examples of the latter.

    A multivariate analysis of the prognostic factors was carried out on a series of 546 differentiated thyroid cancers followed for 8 to 40 years. For survival, the highest risk factor was associated with age; tumors diagnosed in patients younger than 45 years had higher relapse-free survival (RFS) and total survival (TS) rates and a slower growth rate. In children, although the RFS and TS at 15 years were high, they decreased later. The second independent prognostic factor was histology. There was no difference between papillary and follicular well-differentiated (FWD) tumors, but follicular moderately differentiated (FMD) had lower TS and RFS. Among FMD cancers, relapses occurred earlier and the interval between relapse and death was shorter. The third factor was sex. Tumors tended to disseminate more in male than in female patients. The survival rate after relapse was the same, however, suggesting that the growth rates are not different. The presence of palpable lymph nodes also had a significant independent impact on both TS and RFS. Patients treated after 1960 have a better outcome than patients treated earlier, although they did not differ in age distribution, histologic characteristics, sex ratio, or incidence of palpable lymph nodes. The distribution of time intervals between treatment and relapse was not compatible with an exponential failure time model but fit with a log-logistic model. Relapses can occur as late as 30 years or more after initial treatment. Elevated levels of circulating thyroglobulin have been observed in about 12% of the patients who had been in complete remission for longer than 20 years.

    Surgical resection is the standard treatment for hepatocellular carcinoma (HCC). However, the role of surgery in treatment of large tumors (10 cm or more) is controversial. We have analyzed, in a single centre, the long-term outcome associated with surgical resection in patients with such large tumors. We retrospectively investigated 166 patients who had undergone surgical resection between July 1995 and December 2006 because of large (10 cm or more) HCC. Survival analysis was done using the Kaplan-Meier method. Prognostic factors were evaluated using univariate and multivariate analyses. Of the 166 patients evaluated, 80% were associated with viral hepatitis and 48.2% had cirrhosis. The majority of patients underwent a major hepatectomy (48.2% had four or more segments resected and 9% had additional organ resection). The postoperative mortality was 3%. The median survival in our study was 20 months, with an actuarial 5-year and 10-year overall survival of 28.6% and 25.6%, respectively. Of these patients, 60% had additional treatment in the form of transarterial chemoembolization, radiofrequency ablation or both. On multivariate analysis, vascular invasion (P < 0.001), cirrhosis (P = 0.028), and satellite lesions/multicentricity (P = 0.006) were significant prognostic factors influencing survival. The patients who had none of these three risk factors had 5-year and 10-year overall survivals of 57.7% each, compared with 22.5% and 19.3%, respectively, for those with at least one risk factor (P < 0.001). Surgical resection for those with large HCC can be safely performed with a reasonable long-term survival. For tumors with poor prognostic factors, there is a pressing need for effective adjuvant therapy.

    Despite the commonness of scabies in Japanese institutional settings, the nationwide prevalence of scabies has not been elucidated. This study was conducted to assess the prevalence of scabies and control measures in Japanese hospitals. A questionnaire on scabies epidemiology (e.g. number of patients and onsets of outbreak) and preventive measures were sent to psychiatric hospitals and long-term care hospitals nationwide (n = 1795) in January 2005. Seven hundred and forty-one hospitals responded (41.3%). Three hundred and thirty-three (44.9%) respondent hospitals had one or more scabies cases in 2004. Among 159 hospitals that had experienced scabies outbreak, only 32 of them reported cases of crusted scabies. Multivariate regression analysis showed that hospitals had a greater number of beds, and that acute- and long-term care wards were more likely to experience scabies onsets. Hospitals that compiled their infection control manuals on scabies, treated suspicious patients with scabicides without confirmed diagnosis, and performed skin checkup of inpatients were more likely to experience scabies cases. Infection control personnel should be aware that unrecognized crusted scabies can cause outbreaks. Higher patient turnover is a risk factor for scabies introduction into a hospital. Preventive measures against scabies, such as patient screening at admission and treating all suspicious patients without confirmed diagnosis, were not effective to avoid scabies introduction.

    The long-term operation of two thermophilic anaerobic submerged membrane bioreactors (AnSMBRs) was studied using acidified and partially acidified synthetic wastewaters. In both reactors, cake formation was identified as the key factor governing critical flux. Even though cake formation was observed to be mostly reversible, particle deposition proceeds fast once the critical flux is exceeded. Very little irreversible fouling was observed during long-term operation, irrespective of the substrate. Critical flux values at the end of the reactors operation were 7 and 3L/m(2)h for the AnSMBRs fed with acidified and partially acidified wastewaters, respectively, at a gas superficial velocity of 70m/h. Small particle size was identified as the responsible parameter for the low observed critical flux values. The degree of wastewater acidification significantly affected the physical properties of the sludge, determining the attainable flux. Based on the fluxes observed in this research, the membrane costs would be in the range of 0.5euro/m(3) of treated wastewater. Gas sparging was ineffective in increasing the critical flux values. However, preliminary tests showed that cross-flow operation may be a feasible alternative to reduce particle deposition.

  15. Soil Microbial Community Responses to Long-Term Global Change Factors in a California Grassland

    2015-12-01

    Soil fungal and bacterial communities act as mediators of terrestrial carbon and nutrient cycling, and interact with the aboveground plant community as both pathogens and mutualists. However, these soil microbial communities are sensitive to changes in their environment. A better understanding of the response of soil microbial communities to global change may help to predict future soil microbial diversity, and assist in creating more comprehensive models of terrestrial carbon and nutrient cycles. This study examines the effects of four global change factors (increased temperature, increased variability in precipitation, nitrogen deposition, and CO2 enrichment) on soil microbial communities at the Jasper Ridge Global Change Experiment (JRGCE), a full-factorial global change manipulative experiment on three hectares of California grassland. While similar studies have examined the effects of global change on soil microbial communities, few have manipulated more factors or been longer in duration than the JRGCE, which began field treatments in 1998. We find that nitrogen deposition, CO2 enrichment, and increased variability in precipitation significantly affect the structure of both fungal and bacterial communities, and explain more of the variation in the community structures than do local soil chemistry or aboveground plant community. Fungal richness is correlated positively with soil nitrogen content and negatively with soil water content. Arbuscular mycorrhizal fungi (AMF), which associate closely with herbaceous plants' roots and assist in nutrient uptake, decrease in both richness and relative abundance in elevated CO2 treatments.

    Various epidemiologic factors have been shown to influence the risk of ovarian cancer development. Given the high fatality associated with this disease, it is of interest to evaluate the association of prediagnostic hormonal, reproductive, and lifestyle exposures with ovarian cancer-specific survival. We included 1421 patients with invasive epithelial ovarian cancer diagnosed in Ontario, Canada. Clinical information was obtained from medical records and prediagnostic exposure information was collected by telephone interview. Survival status was determined by linkage to the Ontario Cancer Registry. Proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for ovarian cancer-specific mortality associated with each exposure. Analyses were stratified by histologic subtype to further investigate the associations of risk factors on ovarian cancer-specific mortality. After a mean follow-up of 9.48 years (range 0.59-20.32 years), 655 (46%) women had died of ovarian cancer. Parity (ever) was associated with a significant 29% decreased mortality risk compared with nulliparity (HR=0.71; 95% CI 0.54-0.93; P=0.01). There was a borderline significant association between ever use of oestrogen-containing hormone replacement therapy (HRT) and mortality (HR=0.79; 95% CI 0.62-1.01; P=0.06). A history of cigarette smoking was associated with a significant 25% increased risk of death compared with never smoking (HR=1.25; 95% CI 1.01-1.54; P=0.04). Women with a greater cumulative number of ovulatory cycles had a significantly decreased risk of ovarian cancer-specific death (HR=0.63; 95% CI 0.43-0.94; P=0.02). Increasing BMI (kg m(-2)) 5 years before diagnosis was associated with an increased risk of death (HR=1.17; 95% CI 1.07-1.28; P=0.0007). Other hormonal or lifestyle factors were not significantly associated with ovarian cancer-specific mortality. Parity, ovulatory cycles, smoking, and BMI may affect survival following the

    Several types of hippocampal interneurons exhibit a form of long-term potentiation (LTP) that depends on Ca(2+)-permeable AMPA receptors and group I metabotropic glutamate receptors. Several sources of evidence point to a presynaptic locus of LTP maintenance. The retrograde factor that triggers the expression of LTP remains unidentified. Here, we show that trains of action potentials in putative oriens-lacunosum-moleculare interneurons of the mouse CA1 region can induce long-lasting potentiation of stimulus-evoked excitatory postsynaptic currents that mimics LTP elicited by high-frequency afferent stimulation. We further report that blockers of nitric oxide production or TRPV1 receptors failed to prevent LTP induction. The present results add to the evidence that retrograde signalling underlies N-methyl-d-aspartate (NMDA) receptor-independent LTP in oriens interneurons, mediated by an unidentified factor.

    Metabolic memory (MM) is defined as the persistence of diabetic (DM) complications even after glycemic control is pharmacologically achieved. Using a zebrafish diabetic model that induces a MM state, we previously reported that, in this model, tissue dysfunction was of a heritable nature based on cell proliferation studies in limb tissue and this correlated with epigenetic DNA methylation changes that paralleled alterations in gene expression. In the current study, control, DM, and MM excised fin tissues were further analyzed by MeDIP sequencing and microarray techniques. Bioinformatics analysis of the data found that genes of the DNA replication/DNA metabolism process group (with upregulation of the apex1, mcm2, mcm4, orc3, lig1, and dnmt1 genes) were altered in the DM state and these molecular changes continued into MM. Interestingly, DNA methylation changes could be found as far as 6-13 kb upstream of the transcription start site for these genes suggesting potential higher levels of epigenetic control. In conclusion, DNA methylation changes in members of the DNA replication/repair process group best explain the heritable nature of cell proliferation impairment found in the zebrafish DM/MM model. These results are consistent with human diabetic epigenetic studies and provide one explanation for the persistence of long term tissue complications as seen in diabetes.

    In this study, 29 patients with porous high-density polyethylene (group A) and 29 patients with septal cartilage (group B) were enrolled for either spreader or extended septal graft. By questionnaire or telephone survey, the authors evaluated patients' cosmetic satisfaction and complications. The authors also used postoperative photographs to evaluate cosmetic results. For the functional analysis, the change of visual analog scale of nasal obstruction and change of minimal cross-sectional area using acoustic rhinometry were compared. Of 29 patients in group A, 27 were totally satisfied with the results. There was no complication except for 2 cases of extrusion during 5.3 ± 1.8 years. The patients in group A showed more decrease of nasal obstruction by visual analog scale and more improvement of minimal cross-sectional area as compared with those in group B. Therefore, porous high-density polyethylene is an ideal alloplastic material for spreader or extended septal graft in rhinoplasty in both cosmetic and functional aspects. And it is also safe and stable over a long-term period.

    Background Few prospective studies have examined the relationship between sun exposure, other potential risk factors, and risk of different skin cancers [including basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma] simultaneously. Methods We evaluated the association between a number of potential risk factors and skin cancer risk in a cohort of 108,916 US women, the Nurses’ Health Study II (1989-2009). Results During 2.05 million years of follow-up, we identified 6,955, 880, and 779 diagnoses of BCC, SCC, and melanoma, respectively. Compared to participants in the lowest quintile of cumulative ultraviolet flux in adulthood, participants in the highest quintile had multivariable-adjusted relative risks (RR) of 2.35 (Ptrend<0.0001) for BCC, 2.53 (Ptrend=0.009) for SCC, and 0.68 (Ptrend=0.38) for melanoma. In contrast, the RRs were 1.68 (95%CI: 1.55-1.82) for BCC, 1.68 (95%CI: 1.34-2.11) for SCC and 1.80 (95%CI: 1.42-2.28) for melanoma for participants with ≥5 blistering sunburns when compared to participants without sunburn between ages 15-20. We found significant interactions between family history of melanoma, number of blistering sunburns between ages 15-20 and BCC risk, and between sunburn reaction as a child/adolescent and SCC risk (all Pinteraction<0.05). Conclusion In a cohort of US women, we found that sun exposures in both early life and adulthood were predictive of BCC and SCC risks, whereas melanoma risk was predominantly associated with sun exposure in early life. Impact Our results may have potential implications for the prevention of skin cancers. PMID:24876226

    Disorders of renal system can cause renal failure; therefore screening is necessary especially in workers who are exposed to harmful materials. Hypertension, diabetes mellitus, and hazardous exposures are non-occupational and occupational risk factors for renal diseases. The objective of this study was to determine the effects of working in automotive industry on renal function in Iran. In a historical cohort study, workers of automotive industry who worked in production and had low exposure to metal fumes were selected and divided to three groups with 5-10, 11-20, and 21-30 years work duration. risk factors for renal diseases were collected and analyzed with SPSS using one-way ANOVA, correlation coefficient and with P < 0.05 and relative risk with a confidence interval (CI). The means of work duration in Groups (A), (B) and (C) were 9.8 (0.6), 13.8 (2.0), 22.3 (1.6) years respectively with ANOVA (F) =187.864 and P < 0.01. Glomerular filtration rate (GFR) was 59.75 (0.70), 59.16 (1.52) and 59.10 (2.23) in Groups (A), (B), and (C) respectfully The relative risk of creatinine clearance, uric acid and mean blood pressure were the highest in Group (B); 1.970 - CI, 0.541-7.169, 1.571 95% CI: 0.198-12.470, and 1.519 95% CI: 0.425-5.426, but the differences were not significant. GFRs were decreased with work duration, but the differences were not significant. Working in automotive Industry with low exposure to toxic metals and solvents has no significant effect on GFR, creatinine clearance, uric acid, and mean blood pressure.

    Background: Disorders of renal system can cause renal failure; therefore screening is necessary especially in workers who are exposed to harmful materials. Hypertension, diabetes mellitus, and hazardous exposures are non-occupational and occupational risk factors for renal diseases. Aim: The objective of this study was to determine the effects of working in automotive industry on renal function in Iran. Subjects and Methods: In a historical cohort study, workers of automotive industry who worked in production and had low exposure to metal fumes were selected and divided to three groups with 5–10, 11–20, and 21–30 years work duration. risk factors for renal diseases were collected and analyzed with SPSS using one-way ANOVA, correlation coefficient and with P < 0.05 and relative risk with a confidence interval (CI). Results: The means of work duration in Groups (A), (B) and (C) were 9.8 (0.6), 13.8 (2.0), 22.3 (1.6) years respectively with ANOVA (F) =187.864 and P < 0.01. Glomerular filtration rate (GFR) was 59.75 (0.70), 59.16 (1.52) and 59.10 (2.23) in Groups (A), (B), and (C) respectfully The relative risk of creatinine clearance, uric acid and mean blood pressure were the highest in Group (B); 1.970 - CI, 0.541–7.169, 1.571 95% CI: 0.198–12.470, and 1.519 95% CI: 0.425–5.426, but the differences were not significant. Conclusion: GFRs were decreased with work duration, but the differences were not significant. Working in automotive Industry with low exposure to toxic metals and solvents has no significant effect on GFR, creatinine clearance, uric acid, and mean blood pressure. PMID:25861528

    The natural course of adrenal incidentalomas and the risk that such lesions evolve toward hormonal hypersecretion or malignancy are still under evaluation. Of 246 consecutive patients with adrenal incidentaloma studied at our institution in the last 15 yr, 91 underwent surgery. Of the remaining patients, a group of 75 (52 females and 23 males; median age, 56 yr; range, 19-77 yr) with incidentally discovered asymptomatic adrenal masses (60 unilateral and 15 bilateral; median diameter, 2.5 cm; range, 1.0-5.6) was enrolled in an endocrine and morphological follow-up of at least 2 yr after diagnosis (median, 4 yr; range, 2-10). During follow-up, no patients developed malignancy; 9 showed mass enlargement, with appearance of a new mass in the contralateral gland in 2; 3 developed adrenal hyperfunction (overt Cushing's syndrome in 2, nonclinical hypercortisolism in 1); and 3 showed adrenal mass enlargement associated with adrenal hyperfunction (nonclinical hypercortisolism in 2, pheochromocytoma in 1). The estimated cumulative risks to develop mass enlargement and hyperfunction were 8% and 4%, respectively, after 1 yr, 18% and 9.5% after 5 yr, and 22.8% and 9.5% after 10 yr. Nine risk factors for adrenal mass enlargement or hyperfunction were arbitrarily selected and evaluated: sex, age, presence of obesity, hypertension, diabetes, abnormal endocrine tests, mass size, mass location, and scintigraphic uptake pattern. Three of them attained statistical significance: mass size of 3 cm or more at diagnosis and exclusive radiocholesterol uptake by the mass at scintigraphy had relevance for the occurrence of adrenal hyperfunction, whereas the presence of endocrine test abnormalities at diagnosis had predictive value for mass enlargement. It is concluded that subtle hormonal abnormalities are risk factors for mass size increase, which is not a sign of malignant transformation. Both mass size of 3 cm or more at diagnosis and exclusive radiocholesterol uptake, indicating higher

    Optimisation of reproductive investment is crucial for Darwinian fitness, and detailed long-term studies are especially suited to unravel reproductive allocation strategies. Allocation strategies depend on the timing of resource acquisition, the timing of resource allocation, and trade-offs between different life-history traits. A distinction can be made between capital breeders that fuel reproduction with stored resources and income breeders that use recently acquired resources. In capital breeders, but not in income breeders, energy allocation may be decoupled from energy acquisition. Here, we tested the influence of extrinsic (weather conditions) and intrinsic (female characteristics) factors during energy storage, vitellogenesis and early gestation on reproductive investment, including litter mass, litter size, offspring mass and the litter size and offspring mass trade-off. We used data from a long-term study of the viviparous lizard, Lacerta (Zootoca) vivipara. In terms of extrinsic factors, rainfall during vitellogenesis was positively correlated with litter size and mass, but temperature did not affect reproductive investment. With respect to intrinsic factors, litter size and mass were positively correlated with current body size and postpartum body condition of the previous year, but negatively with parturition date of the previous year. Offspring mass was negatively correlated with litter size, and the strength of this trade-off decreased with the degree of individual variation in resource acquisition, which confirms theoretical predictions. The combined effects of past intrinsic factors and current weather conditions suggest that common lizards combine both recently acquired and stored resources to fuel reproduction. The effect of past energy store points out a trade-off between current and future reproduction.

    Parvovirus B19 is a small, non-enveloped, single-stranded DNA virus with a special affinity for the erythroid progenitor cells of the bone marrow. The first case of parvovirus B19 infection in a kidney transplant recipient (KTR) was reported in 1986. Data on the risk factors and specific clinical characteristics of parvovirus B19 infection remain insufficient. We screened 602 KTRs for parvovirus B19 infection using parvovirus B19 polymerase chain reaction (PCR) from January 1990 to April 2016, and the clinical characteristics of patients with positive results were compared to those of age- and gender-matched patients with negative PCR results. A total of 39 KTRs tested positive for parvovirus B19, and they were compared to 78 age- and gender-matched patients among 563 KTRs who had negative PCR results. In all, 89.7% of positive cases were reported within the first year after kidney transplantation. In multivariate analyses, deceased-donor kidney transplantation (odds ratio [OR] 9.067, 95% confidence interval [CI] 1.668-49.275, P = .011), use of tacrolimus (OR 3.607, 95% CI 1.024-12.706, P = .046), PCR test within 1 year of kidney transplantation (OR 12.456, 95% CI 2.674-58.036, P = .001), and hemoglobin levels (OR 0.559, 95% CI 0.351-0.889, P = .014) showed significant correlations with parvovirus B19 infection. Graft survival did not differ between the two groups during the follow-up period of 111.68 ± 54.54 months (P = .685 by log-rank test). The identification of factors related to positive parvovirus B19 PCR results may promote the early detection of parvovirus B19 infection. Further studies are needed to elucidate the characteristics of parvovirus B19 infection in kidney transplantation. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The amount of medical utilization by Medical Aid recipients was 3.7 times that of patients with Korean Medical Insurance. This study aims to describe the surplus medicine and the medication-related utilization, and to determine factors contributing to surplus medicine. Among those who used copayment-free Class I Medical Aid in 2005, 146,880 subjects who were >/=19 year-old and received >365 days medical treatment per year were studied with their case managers by conducting face-to-face interviews. The analytic methods were description, chi-square, t-tests, ANCOVA and multiple logistic regressions. Most subjects were female (68.6%), the elderly (62.5%), and the separated (61.6%), had an elementary graduation or less (74.8%), and had disabilities (33.2%). The percentage of subjects with surplus medicine was 18.5%. However, the percentage of females, the elderly, those with non-disabilities, the separated, the uneducated, those with a very poor perceived health status and those with an economical burden for medical treatment was 19.3%, 18.9%, 19.0%, 19.3%, 19.0%, 20.2% and 24.3%, respectively. For subjects with surplus medicine, averages for the number of used pharmacies, the pharmacy-visit days and the medication costs were 4.6 drugstores, 34.9 days and approximately 1,124 thousand Won(\\). These values were higher than those without surplus medicine (4.4 drugstores , 33.8 days, and Won(\\)1,110 thousand, respectively). The odds ratios of the contributing factors to surplus medicine were female 1.11 (95% CI=1.07-1.14), the elderly 1.06 (95% CI=1.02-1.10), those with non-disabilities 1.08 (95% CI=1.05-1.12), the separated 1.14 (95% CI=1.10-1.18), the unmarried 1.12 (95% CI=1.07-1.18), the uneducated 1.03 (95% CI=1.01-1.08), those with a very poor perceived health status 1.04 (95% CI=1.01-1.08) and experiencing an economical burden for medical treatment 2.33 (95% CI=2.26-2.40). 18.5% of subjects had surplus medicine with a higher mean of medication cost.

    Epidemiologic studies on the health effects of the Chernobyl disaster have focused largely on physical health, whereas the psychological consequences have received little attention. The authors have assessed the associations of various exposure variables with mental and psychosomatic distress in a sample of 1412 Latvian liquidators drawn from the State Latvian Chernobyl Clean-up Workers Registry. The outcome was a mixed mental-psychosomatic disorder occurring during 1986 to 1995. Comparisons among subgroups of the cohort classified according to exposure type or level were based on the proportional hazards model. Length of work (> or = 28 days) in a 10-km radius from the reactor (relative risk [RR] = 1.39, 95% confidence interval [CI] 1.14-1.70), work (> 1 time) on the damaged reactor roof (RR = 1.46, 95% CI 1.02-2.09), forest work (RR = 1.41, 95% CI 1.19-1.68), fresh fruit consumption (> or = 1 time/day) (RR = 1.72, 95% CI 1.12-2.65) are risk factors for mixed mental-psychosomatic disorder. Construction of the sarcophagus (RR = 1.82, 95% CI 0.89-3.72) is also associated with this outcome, although nonsignificantly. Distinguishing stress-related from radiation-induced effects in this data set was difficult and these findings should provide a basis for later hypothesis testing in other cohorts. PMID:9467079

    To evaluate which clinical residual symptoms, multiorgan failure (MOF) patients may exhibit following discharge from intensive care unit (ICU) and to identify the associated factors. A total of 545 consecutively admitted adult patients with MOF on admission were included in the study. Patients were assesed by a survey 6 and 12 months after discharge from a medical-surgical ICU in Spain. A telephone survey was conducted concerning the clinical symptoms of their stay in ICU. A total of 266 survival patients were followed up; 62.2% were male; age 60±18 years; 67.8% medical patients. Fatigue (173; 76%), sleep disturbances (112; 50%) and depression (109; 48%) were the most common symptoms to appear following hospital discharge. The follow-up revealed frequent "residual" clinical symptoms persisting for almost a year; most notably arthromyalgia and asthenia. Depression symptoms during the first 6 months post-hospital discharge were also common among multiple organ failure survivors. The presence of symptomatology over time is mainly related to a poor functional situation at 6 and 12 months, length of hospital stay and severity score on ICU admission.

    The MetS and cardiovascular disease are leading causes of late morbidity in adult liver transplantation recipients; however, limited data are available in pediatric liver transplantation. A single-center retrospective review was undertaken for patients who had a liver transplantation before 18 yr of age and were >5 yr post-transplantation, to study the prevalence of MetS, its components, and cardiac disorders. Fifty-eight patients were included in the study with a mean age at transplantation of 6.3 ± 6.1 yr and mean follow-up of 14.1 ± 6.0 yr. Of the study group, 41.4% were overweight or obese, with ongoing prednisone use and increased duration of follow-up being significant risk factors. Fifty-three patients had sufficient data for determining MetS, which was present in 17% of the patients. Although the prevalence of MetS is low in pediatric liver transplant recipients, it is associated with CKD and prednisone therapy (p < 0.05). Echocardiography data were available for 23 patients, of whom 43.4% had LVH and 13% had evidence of PH. The spectrum of cardiac disorders in this population is much wider than in adults. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Background Clinical significance of microscopic peritoneal carcinomatosis remained unclear. The aim of this study was to evaluate the prognostic value of microscopic peritoneal carcinomatosis in gastric cancer. Methods From 1996 to 2007, 4426 patients underwent gastrectomy for gastric cancer at Fudan University Shanghai Cancer Center. The clinical and pathological data were reviewed to identify patients with microscopic peritoneal carcinomatosis (group 1). The clinicopathological features and prognosis were examined. Additionally, 242 stage-matched gastric cancer patients without microscopic peritoneal carcinomatosis (group 2) and 118 with macroscopic peritoneal carcinomatosis (group 3) were selected as control groups. Results Microscopic peritoneal carcinomatosis was found in 121 patients. There were 85 males and 36 females (2.36:1). There was a higher incidence rate of large size tumor (≥5 cm) (P = 0.045), Borrmann IV (P = 0.000), and serosal invasion (P = 0.000) in gastric cancer with microscopic peritoneal carcinomatosis compared with the control group. The 5-year survival rate of gastric cancer with microscopic peritoneal carcinomatosis was 24%, significantly poorer than that of the stage-matched control group but better than that of patients with macroscopic peritoneal carcinomatosis. The independent prognostic factors identified included pathological stage and operative curability. Conclusions The presence of microscopic peritoneal carcinomatosis was associated with worse prognosis for gastric cancer, but curative surgery showed potential to improve prognosis. PMID:22615966

    Lithium has been the gold standard in treating bipolar disorder. In recent years, the use of lithium seems to be diminished although it is well tolerated among the bipolar disorder patients. This study aimed to evaluate the efficacy and tolerability of lithium as well as to determine factors associated with lithium response among patient with bipolar disorder. A retrospective study was done in a tertiary care hospital in Malaysia which included 47 bipolar disorder patients that were prescribed with lithium maintenance therapy in the time frame of January 2009 until December 2013. Of all the baseline characteristics tested, only psychotic feature differentiated lithium monotherapy group and combination therapy group significantly (χ(2)=4.732, p=0.03). When compared to period before lithium maintenance, all outcome measures (i.e. annual relapse rate, proportion time spent ill and duration of mood episode) showed significant improvement after lithium maintenance in both treatment groups. Lithium discontinuation only occurred in five cases of adverse effects. Predominant depressive mood episode before lithium maintenance (OR=0.159, p=0.033) and first euthymic interval after lithium maintenance (OR=1.109, p=0.047) significantly predicted lithium response. Lithium significantly reduced the frequency and time spent in relapse in patients with bipolar disorder. Predominant depressive mood polarity before lithium maintenance and longer first euthymic interval after lithium maintenance had been identified to predict lithium response significantly.

    Background and Objectives We studied the results of patient management for left isomerism (LI) and sought to determine factors that may influence survival and prognosis. Subjects and Methods We reviewed the medical records of 76 patients who were compatible with LI criteria between 1982 and 2014. Results Of the total study population, 29 patients (38.1%) had functional univentricular heart disease, 43 patients (56.5%) had cardiac anomalies suitable for biventricular hearts, and four patients (5.2%) had normal heart structure. Extracardiac anomalies were noted in 38.1% of the study population, including biliary atresia in 7.8% of all patients. Of the 25 patients who underwent Kawashima procedures, 24.0% developed pulmonary arteriovenous fistulas (PAVFs). During the median follow-up period of 11.4 years (range: 1 day to 32 years), 14 patients died. The 10-year, 20-year, and 30-year survival rates were 87%, 84%, and 76%, respectively. Preoperative dysrhythmia and uncorrected atrioventricular valve regurgitation were significantly associated with late death. There was no significant difference in the number of surgical procedures and in survival expectancy between patients in the functional single-ventricle group and in the biventricular group. However, late mortality was higher in functional single-ventricle patients after 18 years of age. Conclusion Patients with LI need to be carefully followed, not only for late cardiovascular problems such as dysrhythmia, valve regurgitation, and the development of PAVFs, but also for noncardiac systemic manifestations.

    The aim of this study was to evaluate female urethral cancer (UCa) patients treated and followed-up during a time period spanning more than 20 yr at single institution in Korea. We reviewed medical records of 21 consecutive patients diagnosed with female UCa at our institution between 1991 and 2012. After exclusion of two patients due to undefined histology, we examined clinicopathological variables, as well as survival outcomes of 19 patients with female UCa. A Cox proportional hazards ratio model was used to identify significant predictors of prognosis according to variables. The median age at diagnosis was 59 yr, and the median follow-up duration was 87.0 months. The most common initial symptoms were voiding symptoms and blood spotting. The median tumor size was 3.4 cm, and 55% of patients had lesions involving the entire urethra. The most common histologic type was adenocarcinoma, and the second most common type was urothelial carcinoma. Fourteen patients underwent surgery, and 7 of these patients received adjuvant radiation or systemic chemotherapy. Eleven patients experienced tumor recurrence after primary therapy. Patients with high stage disease, advanced T stage (≥T3), and positive lymph nodes had worse survival outcomes compared to their counterparts. Particularly, lymph node positivity and advanced T stage were significant predictive factors for all survival outcomes. Tumor location was the only significant predictor for recurrence-free survival. Although our study included a small number of patients, it conveys valuable information about this rare female urologic malignancy in a Korean population.

    The aim of this study is to describe and determine the factors associated with the quality of life (QoL) of patients with dementia living in nursing homes as perceived by themselves and by proxies (both family and staff). Data on residents with dementia were collected in 11 nursing homes. The Quality of Life-Alzheimer's Disease Scale (QoL-AD) residential version was directly applied to residents with dementia diagnosis and Mini-Mental State Examination score of less than 27, randomly selected in each center. Residents' QoL was further assessed from the perspective of some close relative and staff member. Altogether, 102 data sets from residents, 184 from relatives, and 197 from staff members were collected. Stepwise multiple linear regression analysis showed that depression and cognitive function were the best predictors of self-rated QoL. Predictors of family-rated QoL were resident's functional capacity to carry out activities of daily living (ADL), the family member paying for the nursing home fees, and use of feeding tubes as part of the resident's care. Predictors of staff-rated QoL were resident's functional capacity to carry out ADL, cognitive impairment and depression, staff-member's work pattern of shifts (rotating vs. permanent) and type of center administration (public vs. private). Explained variance for the three models was 42%, 25% and 41% respectively. The QoL perception by persons with dementia living in a nursing home is mainly affected by their emotional state (depression level), while proxies' perceptions (both family and staff) are mainly associated with patients' functional autonomy in daily living. Therefore, perspectives of persons with dementia and their informants are not congruent. Moreover, facility features and family and staff members' personal features do not affect QoL ratings.

    Transforming growth factor-beta (TGF-beta) modulates growth and differentiation in many cell types and is abundant in bone matrix. We recently showed that human cord blood monocytes cultured in the presence of 1,25(OH)2D3 acquire some features of osteoclast precursors. Since TGF-beta has been shown to influence bone resorption in organ culture, we have studied the effect of TGF-beta (1-1,000 pg/ml) on cord blood monocyte cultures. These cells were cultured on plastic substrate during 3 weeks in the presence of 20% horse serum and 10(-9) M 1,25(OH)2D3. TGF-beta, from a concentration of 10 pg/ml in the culture medium, decreased in a dose dependent manner the formation of multinucleated cells. At a concentration of TGF-beta of 1 ng/ml, the multinucleated cells were reduced to 2.1% +/- 0.3%, compared to 19.3% +/- 1.5% in control cultures. TGF-beta inhibited in a dose-dependent manner the proliferation of cord blood monocytes as assessed by 3H-thymidine incorporation at 7 and 14 days of culture. The fusion index was also decreased by 3 weeks of treatment with TGF-beta. Indomethacin did not reverse the inhibitory effects of TGF-beta. The expression of the osteoclastic phenotype was assessed using two different antibodies: 23C6, a monoclonal antibody directed against the vitronectin receptor, which is highly expressed by osteoclasts but not by adult monocytes, and an antibody to HLA-DR, which is not present on osteoclast. TGF-beta decreased the expression of HLA-DR and increased in a dose-dependent manner the proportion of 23C6-labeled cells; these results suggest that TGF-beta could modulate a differentiation effect to the osteoclastic phenotype. However, when cord blood monocytes were cultured on devitalized rat calvariae prelabeled with 45Ca, TGF-beta did not induce any 45Ca release from bone cultured with monocytes.

    The risk factors associated to long-term survival were assessed in patients with liver metastases of colorectal carcinoma undergoing ablative therapies. Single-centre cohort study, retrospectively analysed and prospectively collected consecutive patients with unresectable metastatic liver disease of colorectal carcinoma treated with ablative therapies between 1996 and 2013. Factors associated with survival time were identified using Cox's proportional hazard model with time-dependent covariates. A forward variable selection based on Akaike information criterion was performed. Relative risk and 95% confidence intervals for each factor were calculated. Statistical significance was set as P<.05. Seventy-five patients with liver metastases of colorectal cancer, with a mean age of 65.6 (10.3) underwent 106 treatments. Variables selected were good quality of life (RR 0.308, 95% CI 0.150-0.632) and tumour extension (RR 3.070, 95% CI 1.776-5.308). The median overall survival was 18.5 months (95% CI 17.4-24.4). The survival prognosis in median was 13.5 vs. 23.4 months for patients with and without tumour extension, and 23.0 vs. 12.8 months for patients with good and fair or poor quality of life, respectively. Good quality of life and tumour extension were the only statistically significant predictors of long-term survival in patients of colorectal carcinoma with liver metastatic disease undergoing ablative treatment with ultrasound.

    Brain metastases (BMs) are the most common malignant brain tumors in adults. Despite multimodal treatment options such as microsurgery, radiotherapy and chemotherapy, prognosis still remains very poor. Non-small cell lung cancer (NSCLC) constitutes the most common source of brain metastases. In this study, prognostic factors in this patient population were identified through an in-depth analysis of clinical parameters of patients with BMs from NSCLC. Clinical data of 114 NSCLC cancer patients who underwent surgery for BMs at the University Hospital Heidelberg were retrospectively reviewed for age, gender, type of treatment, time course of the disease, presence of neurologic symptoms, Karnofsky Performance Status (KPS), smoking history, presence of extracranial metastases at initial diagnosis of NSCLC, number, location and size of brain metastases. Univariate and multivariate survival analyses were performed using the Log-rank test and Cox' proportional hazard model, respectively. Median survival time from surgery for BMs was 11.2 months. 18.4% (21 of 114) patients were long-term survivors (>24 months; range 26.3-75.1 months). Age, gender, size and number of intracranial metastases were not significantly associated with patient survival. Univariate analysis identified complete resection, postoperative whole brain radiotherapy (WBRT) and a preoperative KPS of >80% as positive prognostic factors. Infratentorial location and presence of extracranial metastases were shown to be negative prognostic factors. Surgery for the primary tumor was associated with a superior patient outcome both in univariate and multivariate analyses. Our data strongly suggest that surgical treatment of the primary tumor and complete resection of brain metastases in NSCLC patients followed by WBRT improve survival. Moreover, long-term survivors (>2 years) were more frequent than previously reported. Copyright © 2016 Elsevier B.V. All rights reserved.

    OBJECTIVES Malignant peritoneal mesothelioma (MPM) is a primary cancer that arises diffusely from the serosa of the peritoneum. Morbidity and mortality are almost invariably due to loco-regional progression; cytoreduction with intra-operative or peri-operative high dose regional chemotherapy has been established as the preferred approach in selected patients. This study was performed to identify factors associated with long-term outcome. METHODS Between January, 1992 and 2010, 211 patients with MPM treated at three major referral centers with operative cytoreduction and hyperthermic intra-operative peritoneal chemotherapy (HIPEC) were analyzed. RESULTS The median actuarial overall survival was 38.4 months; the actuarial 5 and 10 year survivals were 41% and 26%, respectively. On multivariate analysis, factors independently associated with favorable outcome were age less than 60 years (p< 0.01), complete or near complete (R0–1) versus incomplete (R2–3) resection (p< 0.02), low versus high histologic grade (P< 0.01), and the use of cisplatin versus mitomycin-C during HIPEC (p< 0.01). There was an insignificant trend towards female gender and improved survival (male Hazard Ratio: 1.46, 95% CI: 0.89–2.41, p=0.13). CONCUSIONS Operative cytoreduction with HIPEC is associated with long term survival in patients with MPM. Factors associated with survival include age, complete or near complete gross tumor resection, histologic tumor grade, and HIPEC with cisplatin. The fact that cisplatin versus mitomycin-c was independently associated with improved survival demonstrates a salutary effect for HIPEC with cisplatin in the management of patients with MPM.

    To determine the long-term prognosis of low-frequency hearing loss and predictive factors for the 10-year outcome of low-frequency hearing loss. Case series with chart review. Tertiary referral center. From 1979 to 1998, 466 consecutive patients with low-frequency hearing loss received initial treatment at the Hearing and Tinnitus Clinic of Keio University Hospital. Of the 49 eligible patients, pure-tone threshold data obtained over a period of 10 years after onset of low-frequency hearing loss were available for analysis. To determine the progression of hearing loss, we analyzed audiometric pattern changes. We also examined how the following factors affected 10-year prognosis: sex, age, side of hearing loss, accompanying dizziness, pre-therapeutic hearing thresholds at low frequencies, initial therapy results, and fluctuation of hearing during the first year after onset. High- and pan-frequency hearing loss increased as time progressed. About half of the cases developed high- or pan-frequency hearing loss within 10 years of onset. Audiometric patterns measured at 10 years significantly correlated with those measured at one (r = 0.57), three (r = 0.73), and five years (r = 0.85). The 10-year prognosis significantly correlated with only two factors: initial therapy results (r = 0.49) and fluctuation of hearing during the first year (r = 0.43). About half of the cases in our study developed high- or pan-frequency hearing loss within 10 years of onset of low-frequency hearing loss. The initial therapy results and fluctuation of hearing during the first year may indicate the long-term prognosis of patients presenting with low-frequency hearing loss.

    Our aim was to determine factors that affect maternal serum magnesium (Mg) levels, to help ensure the safety and efficacy of long-term magnesium sulfate (MgSO4 ) therapy for threatened preterm labor in singleton and twin pregnancies. We retrospectively and arbitrarily studied 100 patients (singleton pregnancy, n = 65; twin pregnancy, n = 35) who received i.v. MgSO4 for >48 h for tocolysis of threatened preterm labor. We used multiple regression analysis to investigate the functional relations between the candidate factors and maternal serum Mg levels. MgSO4 was administered as a loading dose of 3 g for 1 h followed by a maintenance dose of 1.0-2.0 g/h. There were no maternal severe adverse events related to the elevated Mg levels in any of the subjects. The results of multiple regression analysis revealed that total dose of MgSO4 for 24 h before blood collection (g/day), total serum protein level (g/dL), serum total calcium level (mg/dL), serum creatinine level (mg/dL) and maternal bodyweight (kg) significantly affected maternal serum Mg levels in both singleton and twin pregnancies (all P-values were < 0.001). Gestational age (weeks) and period of MgSO4 administration (days) at blood collection had no significant effect in singleton or twin pregnancies. Our study statistically shows that dose of MgSO4 , total serum protein level, serum total calcium level, serum creatinine level and maternal bodyweight are key factors to achieving safe and effective long-term tocolysis with MgSO4 in not only singleton but also twin pregnancies. © 2015 The Authors.

    To evaluate long-term results of endovascular procedures in treatment of venous juxta-anastomotic stenoses (JASs) of native forearm radiocephalic arteriovenous fistulas (AVFs) and to identify prognostic factors influencing these results. During a 124-month period, 147 endovascular interventions were performed in 75 forearm radiocephalic AVFs with JASs defined as stenoses located within the first 5 cm of the outflow vein. Prognostic factors included patient characteristics (age, sex, diabetes), AVF-related characteristics (location on forearm, age, maturity), stenosis-related characteristics (position relative to anastomosis, length, and degree), and degree of residual stenosis and delay of restenosis after the first endovascular procedure. At 1 and 3 years, access primary patency (PP) rates were 46.6% (95% confidence interval [CI], 36.3%-59.9%) and 25.5% (95% CI, 15.7%-41.6%) and assisted PP (APP) rates were 81.3% (95% CI, 72.6%-91.1%) and 63.2% (95% CI, 50.6%-79.0%), respectively. Stenosis degree of 50%-75% (P = .017), stenosis length of 10 mm or more (P = .017), and time before first restenosis of less than 6 months (P = .03) significantly increased the frequency of endovascular procedures during follow-up. However, only the degree of residual stenosis after the first endovascular treatment significantly affected long-term APP (P = .039). When residual stenosis was less than 50%, 1- and 2-year access APP rates were 84.6% (95% CI, 75.8%-94.4%) and 76.1% (95% CI, 64.6%-89.6%), respectively. When it was at least 50%, the respective APP rates were 62.3% (95% CI, 38.9%-99.9%) and 46.8% (95% CI, 22.4%-97.7%). Endovascular treatment of JASs in forearm radiocephalic AVFs provides good long-term results except when the residual stenosis after the first procedure is 50% or more. In that case, the optimal treatment remains to be determined. Copyright © 2013 SIR. Published by Elsevier Inc. All rights reserved.

    PurposeEvaluation of long-term outcomes of venoplasty and Gianturco stents to treat inferior vena cava (IVC) obstruction after liver transplantation.MethodsWe retrospectively analyzed records from 33 consecutive adult patients referred with the intent to treat suspected IVC obstruction after liver transplantation. Treatment was performed for occlusion or stenosis with a gradient exceeding 3 mmHg. The primary treatment was venoplasty and, if refractory, Gianturco stent placement. Recurrence prompted repeat venoplasty or stent placement.ResultsOf the 33 patients, 25 (aged 46.9 ± 12.2 years) required treatment at a mean of 2.3 years (14 days to 20.3 years) after transplantation. For technically successful cases, primary treatment was venoplasty alone (14) or with stent placement (10). Technical success was 96 % (24 of 25) reflecting failure to cross one occlusion. Clinical success was 88 % (22 of 25) reflecting the technical failure and two that died of unrelated complications within 5 weeks. Cumulative primary patencies were 57.1 % at 6 months (n = 21) and 51.4 % at 1 (n = 10), 3 (n = 7), 5 (n = 6), and 7 (n = 5) years. Cumulative primary assisted patency was 95.2 % at 6 months (n = 21) and at 1 (n = 15), 3 (n = 9), 5 (n = 8), and 7 (n = 8) years. The 17 patients stented for refractory (n = 10) or recurrent (n = 7) stenosis had cumulative primary and primary assisted patencies of 86.0 and 100 %, respectively, from 6 months (n = 14) to 7 years (n = 3). No major complications occurred; one fractured stent was observed after 11.6 years.ConclusionFor IVC obstruction following liver transplantation, excellent long-term outcomes can be achieved by venoplasty and Gianturco stent placement.

    The Ontario Farm call Surveillance Project (OFSP) was a practitioner-based, syndromic surveillance system for livestock disease. Three data-recording methods (paper, web-based, and handheld electronic) used by participating veterinarians were compared for timeliness (when the report arrived at the OFSP office), completeness of the report, and the usage and costs of incentives offered to veterinarians as compensation for their time to record data. There were no statistically significant differences in these parameters among the 3 data-recording methods. This indicates that different data-recording methods can be used within a single veterinary surveillance program while maintaining data integrity and timely reporting. Factors such as ease of data collection and providing incentives valued by veterinarians ensured high compliance and long-term participation in the project. It also increased the diversity of the participant group, reducing the likelihood of biased data submissions.

    Sclerotic chronic graft-versus-host disease (sclGVHD) is associated with significant morbidity and a poor quality of life. We reviewed 502 patients diagnosed with chronic GVHD and analyzed the incidence and risk factors of sclGVHD and long-term outcomes and immunosuppressive therapy (IST) cessation in patients with sclGVHD. With a median onset at 18 months the cumulative incidence of sclGVHD was estimated at 22.6% at 5 years (95% confidence interval, 18.6% to 26.8%). Univariate and multivariate analysis identified 2 risk factors for sclGVHD: non-T cell depletion (hazard ratio [HR] 9.09, P < .001) and peripheral blood stem cell (HR 3.87, P < .001). Overall survival (OS) at 5 years was significantly better in the sclGVHD group (88.1%) compared with the non-sclGVHD group (62.7%; P < .001), as were nonrelapse mortality (7.3% versus 21.5% at 5 years) and relapse rates (9.1% versus 19.3% at 5 years). There was no difference in the rate of IST cessation at 5 years (44.8% versus 49.9%, P = .312), but there was a trend of longer IST duration in the sclGVHD group compared with the non-sclGVHD group (median 71.6 months versus 62.9 months). In conclusion, T cell depletion and graft source affect the risk of sclGVHD. SclGVHD did not adversely affect long-term outcomes or IST duration.

    Fetuin-A is known as a circulating inhibitor of vascular calcification. Factors associated with serum fetuin-A concentrations after long-term use of different phosphate binders in hemodialysis patients is still uncertain. In the post-hoc study, we analyzed serum fetuin-A and biochemical factors (Ca, P, i-PTH, hsCRP, TG, LDL-C) in 50 hemodialysis patients, who completed a 48-week, open-Label, controlled randomized parallel-group study. 23 patients received sevelamer and 27 patients received calcium carbonate. After the 48-week treatment, the sevelamer group had less serum calcium increment, less iPTH decrement, more ALK-P increment, more hsCRP decrement and more LDL-C decrement. There was no significant difference in the serum fetuin-A decrement between two groups. Decreased serum fetuin-A levels were found after 48-week treatment in both groups: from 210.61 (104.73) to 153.85 (38.64) ug/dl, P = 0.003 in sevelamer group, from 203.95 (107.87) to 170.90 (58.02) ug/mL, P =0.002 in calcium group. The decrement in serum fetuin-A (Δfetuin-A) levels was associated with ΔCa (ρ = - 0.230, P = 0.040), ΔiPTH (ρ = 0.306, P = 0.031) and Δalbumin (ρ = 0.408, P = 0.003), not associated with sevelamer use, ΔP and ΔhsCRP. After long-term sevelamer or calcium carbonate treatment, both groups of maintenance HD patients had lower serum fetuin-A levels. Serum levels of increased calcium, decreased iPTH and decreased albumin were associated with the serum fetuin-A decrement.

    After introduction of MELD-based allocation in Germany, decreased waiting list mortality and increased mortality after transplantation have been reported. This study compares relevant outcome parameters in patients with high MELD ≥30 versus lower MELD scores in a retrospective analysis including 454 consecutively performed liver transplantations in adults (age >16 years) at Hannover Medical School between 01/01/2007 and 31/12/2012 and a follow-up until 31/12/2013. Multivariable risk-adjusted models were applied to identify independent risk factors for 90-day and long-term mortality. MELD score ≥30 (n=117; 26.1%) was an independent risk factor for 90-day mortality (p=0.004, odds ratio: 3.045, 95% CI 1.439-6.498) and long-term mortality (p=0.016, hazard ratio: 1.620, 95% CI 1.095-2.396) and was associated with significantly longer hospital and intensive care unit stays (p<0.001), and death occurred in more cases earlier after transplantation (90-day mortality 21.6% vs. 13.0%; p=0.029). Portal vein thrombosis at transplantation was significantly associated with 90-day mortality after transplantation in patients with MELD scores ≥30 (p=0.041), but this was not the case for patients with MELD scores <30, although portal vein thrombosis was equally frequent in individuals of both groups (3.0% vs. 3.4%, p=0.824). Results of this study suggest that liver transplant recipients with portal vein thrombosis at transplantation should be transplanted before reaching a MELD score ≥30.

    Adjuvant radiotherapy (RT) for endometrial cancer (EC) may affect patients' quality of life (QoL). There is a paucity of data on prognostic factors for long-term QoL and sexual functioning. This study aimed to investigate such factors and assess the role of the vaginal dilator (VD). QoL was assessed in 112 EC patients 6 years (median) after RT. QoL was compared to normative data, and the influence of age, tumor characteristics, lymphadenectomy, RT, and acute toxicities was assessed. VD use and its effect on subjective vaginal shortening/tightness was analyzed. QoL was reduced, particularly in younger patients. Vaginal brachytherapy only and intensity-modulated RT (IMRT) were associated with better global health status and reduced chronic gastrointestinal (GI) symptoms. Higher acute GI toxicity was associated with increased chronic GI symptoms, particularly diarrhea, and reduced role functioning. Higher acute urinary toxicity was associated with increased chronic urological symptoms, muscular/pelvic pain, and chronic GI symptoms, as well as with reduced emotional/social functioning and reduced global health status. Sexual interest/activity was increased despite vaginal dryness and dyspareunia. Sexual interest/activity increased with age. Only few, mainly younger patients used the VD. VD use >1 year was found in women with higher sexual interest/activity. Acute vaginal toxicity and chronic pain prevented VD use. Subjective vaginal shortening/tightness was not reduced in VD users. RT technique and acute toxicities are prognostic for the extent of chronic symptoms and long-term QoL. Sexuality is important even at a higher age. Few patients use the VD and a reduction of subjective vaginal shortening/tightness was not achieved.

    To examine factors impacting long-term functional outcomes and psychological sequelae in persons with primary brain tumours (BT) in an Australian community cohort. Participants (n = 106) following definitive treatment for BT in the community were reviewed in rehabilitation clinics to assess impact on participants' current activity and restriction in participation, using validated questionnaires: Functional Independence Measure (FIM), Perceived Impact Problem Profile (PIPP), Depression Anxiety Stress Scale, Cancer Rehabilitation Evaluation System-Short Form and Cancer Survivor Unmet Needs Measure. Mean age of the participants was 51 years (range 21-77 years), majority were female (56 %) with median time since BT diagnosis 2.1 years and a third (39 %) had high grade tumours. Majority showed good functional recovery (median motor FIM score 75). Over half reported pain (56 %), of which 42 % had headaches. Other impairments included: ataxia (44 %), seizures (43 %); paresis (37 %), cognitive dysfunction (36 %) and visual impairment (35 %). About 20 % reported high levels of depression, compared with only 13 % in an Australian normative sample. Two-third (60 %) participants reported highest impact on the PIPP subscales for psychological wellbeing (scores of >3 on 6-point scale) and participation (45 %). Factors significantly associated with poorer current level of functioning and wellbeing included: younger participants (≤40 years), recent diagnoses, aggressive tumour types and presence of pain. No significant differences in scale scores were found across various treatments (surgery, chemotherapy or radiotherapy) on outcomes used. Rehabilitation for BT survivors is challenging and requires long-term management of psychological sequelae impacting activity and participation. More research into participatory limitation is needed to guide treating clinicians.

    With the development of society and the economy, many Chinese cities are shrouded in pollution haze for much of the year. Scientific studies have identified various adverse effects of air pollutants on human beings. However, the relationships between air pollution and blood lipid levels are still unclear. The objective of this study is to explore the short and long-term effects of air pollution on eight blood lipid markers among elderly hypertension inpatients complicated with or without type 2 diabetes (T2D). Blood lipid markers which met the pre-established inclusion criteria were exported from the medical record system. Air pollution data were acquired from the official environmental protection website. Associations between the air quality index and the blood lipid indexes were analyzed by one-way ANOVA and further Bonferroni correction. In an exposure time of 7 days or longer, blood lipid markers were somewhat affected by poor air quality. However, the results could not predict whether atherosclerosis would be promoted or inhibited by poorer air condition. Changes of blood lipid markers of hypertension inpatients with or without T2D were not completely the same, but no blood lipid markers had an opposite trend between the two populations. The air quality index was associated with changes to blood lipid markers to some extent in a population of hypertension inpatients with or without T2D. Further studies are needed to investigate the potential mechanism by which air pollutants induce blood lipids changes.

    The purpose of this study was to develop the Personhood Questionnaire (PQ) to determine the factor structure of "personhood" for elderly healthcare services and identify personhood components other than PQ items. We enrolled 314 healthcare professionals at long-term care facilities in Japan. Participants completed a questionnaire consisting of 17 PQ items. The PQ was designed to assess the degree of need in elderly healthcare services on a 5-point Likert scale (Question 1), and identify personhood components other than PQ items (Question 2). We performed factor analysis for answers to Question 1, and text mining and cluster analysis for answers to Question 2. Factor analysis revealed a four-factor structure. Cronbach's α was 0.87 for the 17 original items and 0.86 for the 15 items after removing two items. Text mining identified 27 personhood components, which were classified into three clusters. The second cluster consisted of non-PQ items. Factor 1 was "forming daily life," factor 2 was "forming career and context," factor 3 was "affecting psychological behavior," and factor 4 was "forming basic attributes." Components of the second cluster require further examination before incorporation into the concept of personhood. • Improving the quality of individualized care, in which "personhood" and dignity of elderly people are respected, is an urgent goal. • The Model of Human Occupation (MOHO), a conceptual practice model for occupational therapy, should be used jointly with the International Classification of Functioning, Disability and Health (ICF) to establish the concept of personhood. • The construction of personhood in elderly health care services consists of a four-factor structure, including "forming daily life," "forming career and context," "affecting psychological behavior," and "forming basic attributes." • This study suggests that provision of high-quality individualized care can be achieved by promoting services that focus on "forming daily

    Plant growth response to salinity on a scale of years has not been studied in terms of growth analysis. To gain insights into this topic, 2-year-old Mediterranean Fan Palm (Chamaerops humilis L.) and Mexican Fan Palm (Washingtonia robusta H. Wendl) seedlings, each with its own distinct plant morphology, were grown for 2 years in a peat soil and irrigated with water of 2 dS m(-1) (control) or 8 dS m(-1) (saline). Plants were harvested on seven occasions and the time trends in relative growth rate (RGR, the rate of increase of biomass per unit of biomass already existing) and its components were analysed. In the long term, salinity produced a slight reduction in the mean RGR, values in both species. In the short term, salinity caused a reduction in RGR. However, during the second year, plants irrigated with 8 dS m(-1) grew somewhat more quickly than the control plants, probably as a result of delay in the growth kinetics due to salinity. Regarding RGR components, leaf nitrogen productivity (the rate of biomass gain per unit leaf N and time) was the major factor causing the differences in RGR resulting from salinity. Washingtonia robusta showed a relatively high plasticity in plant morphology by increasing root and decreasing stem biomass allocation in the presence of salinity. However, the long-term response of W. robusta to salinity, based to a great extent, on this morphological plasticity, was less effective than that of C. humilis, which is based mainly on the contribution of leaf N to RGR values.

    To investigate the role of putative virulence factors of Streptococcus pyogenes (group A streptococcus; GAS) in causing disease, we introduced specific mutations in GAS strain B514, a natural mouse pathogen, and tested the mutant strains in two models of infection. To study late stages of disease, we used our previously described mouse model (C3HeB/FeJ mice) in which pneumonia and systemic spread of the streptococcus follow intratracheal inoculation. To study the early stages of disease, we report here a model of long-term (at least 21 days) throat colonization following intranasal inoculation of C57BL/10SnJ mice. When the three emm family genes of GAS strain B514-Sm were deleted, the mutant showed no significant difference from the wild type in induction of long-term throat colonization or pneumonia. We inactivated the scpA gene, which encodes a complement C5a peptidase, by insertion of a nonreplicative plasmid and found no significant difference from the wild type in the incidence of throat colonization. However, there was a small but statistically significant decrease in the incidence of pneumonia caused by the scpA mutant. Finally, we demonstrated a very important effect of the hyaluronic acid capsule in both models. Following intranasal inoculation of mice with a mutant in which a nonreplicative plasmid was inserted into the hasA gene, which encodes hyaluronate synthase, we found that all bacteria recovered from the throats of the mice were encapsulated revertants. Following intratracheal inoculation with the hasA mutant, the incidence of pneumonia within 72 h was significantly reduced from that of the control strain (P = 0.006). These results indicate that the hyaluronic acid capsule of S. pyogenes B514 confers an important selective advantage for survival of the bacteria in the upper respiratory tract and is also an important determinant in induction of pneumonia in our model system.

    Large epidemiologic studies have associated gouty arthritis with the risk of coronary heart disease. However, there has been a lack of information regarding the outcomes for patients who have gout attacks during hospitalization for acute myocardial infarction. We reviewed the data of 444 consecutive patients who were admitted to our hospital between 2005 and 2008 due to acute ST elevation myocardial infarction (STEMI). The clinical outcomes were compared between patients with gout attack and those without. Of the 444, 48 patients with acute STEMI developed acute gouty arthritis during hospitalization. The multivariate analysis identified prior history of gout and estimated glomerular filtration rate as independent risk factors of gout attack for patients with acute STEMI (odds ratio (OR) 21.02, 95 % CI 2.96-149.26, p = 0.002; OR 0.92, 95 % CI 0.86-0.99, p = 0.035, respectively). The in-hospital mortality and duration of hospital stay did not differ significantly between the gouty group and the non-gouty group (controls). During a mean follow-up of 49 ± 28 months, all-cause mortality and stroke were similar for both groups. Multivariate Cox regression showed that gout attack was independently associated with short- and long-term adverse non-fatal cardiac events (hazard ratio (HR) 1.88, 95 % CI 1.09-3.24, p = 0.024; HR 1.82, 95 % CI 1.09-3.03, p = 0.022, respectively). Gout attack among patients hospitalized due to acute STEMI was independently associated with short-term and long-term rates of adverse non-fatal cardiac events.

    Background To investigate which factors influence the immediate and long-term outcome of elective electrical cardioversion for persistent (>48h) atrial fibrillation or flutter. Methods In 255 patients, 435 electrical cardioversions were performed. Relevant clinical, electrocardiographic and echocardiographic factors were registered at each cardioversion. Each factor was tested separately in relation to immediate success and the outcome at six months and one year after cardioversion. Results In 70% of the patients, sinus rhythm was restored immediately after electrical cardioversion. After six months only 20% of the patients were still in sinus rhythm, and one year after cardioversion this figure had dropped to 14%. Sotalol used during electrical cardioversion resulted in the highest immediate success. Furthermore, atrial flutter, two or fewer electrical shocks and shocks ≤200 Joules resulted in the highest immediate success rate, whilst hypertensive heart disease resulted in the lowest immediate success rate. However, only shocks ≤200 Joules and a first cardioversion promoted the persistence of sinus rhythm after six months. A normal electrocardiogram, two or more cardioversions in the past and the use of a beta-blocking drug other than sotalol during cardioversion increased the chance of recurrence within six months. The duration of the arrhythmia >one month to 200 Joules and more than two cardioversions in the past were associated with a high number of recurrences one year later. With multivariate analysis we found that atrial flutter, low energy levels, low number of shocks and a long QTc-interval influence the immediate success positively. However, no factor influenced the persistence of sinus rhythm at six months and one year. Conclusion In patients with persistent atrial fibrillation or flutter, only about

    To investigate the irregular antibody production and its relationship with Rh factor genotypes and the loci of thalassemia gene mutations for the β-thalassemic children with long-term transfusion, so as provide experimental basis for clinical safe and effective transfusions for thalassemic children. The peripheral blood from 246 children with β-thalassemia was collected in our hospital; the extraction of genomic DNA and Rh factor (C/c, E/e) genotypes were assayed by PCR-SSP method, the irregular antibodies were screened and identified by serological method, the genotypes for thalassemia and gene mutations were analysed by PCR-RD method. The genotypes of Rh factors classified by PCR- SSP in the 246 cases of β-thalassemia children were as follws: Ce/Ce (143/246, 58.1%), CE/ce (59/246, 24%), cE/cE (14/24, 5.7%), Ce/ce (12/246, 4.9%); The positive rate of irregular antibody was 7.7% (19/246), including anti-E (7/19), anti-c (5/19), anti-C (2/19), anti-E and anti-c (2/19), anti-e (1/19), anti-D (2/19); Of the 19 cases with positive irregular antibody, the genotypings of Rh factor were: Ce/Ce (11/19), CE/ce (2/19), cE/cE (2/19), Ce/ce (2/19), cE/ce (2/19); the gene mutations location of thalassemia for 19 cases with positive irregular antibody: CD41-42M (13/19), CD71-72M (2/19), IVS-II-654M (3/19), -28M (1/19). The irregular antibody production for β-thalassemic children with long-term transfusion may have some relevance with Rh factor genotypes and thalassemia genetic mutations. This study possesses a certain significance for effective prevention of RBC alloimmune response of β-thalassemia children and improvement of efficacy and safety of clinical transfasion blood.

    The prevalence, risk factors, treatment practices, and outcomes of agitation in patients undergoing prolonged mechanical ventilation (PMV) in the long-term acute care hospital (LTACH) setting are not well understood. We compared agitation risk factors, management strategies, and outcomes between patients who developed agitation and those who did not, in LTACH patients undergoing PMV. Patients admitted to an LTACH for PMV over a 1-year period were categorized into agitated and nonagitated groups. The presence of agitation risk factors, management strategies, and relevant outcomes were extracted and compared between the 2 groups. A total of 80 patients were included, 41% (33) with agitation and 59% (47) without. Compared to the nonagitated group, the agitated group had a lower Sequential Organ Failure Assessment score (P < .0006), a greater transfer rate from an academic center (P = .05), a greater delirium frequency at both baseline (P = .04) and during admission (P < .001), and a greater rate of benzodiazepine discontinuation (P = .02). Although the use of scheduled antipsychotic (P = .0005) or restraint (P = .002) therapy was more common in the agitated group, use of benzodiazepines (P = .16), opioids (P = .11), or psychiatric evaluation (P = .90) was not. Weaning success, duration of LTACH stay, and daily costs were similar. Agitation among the LTACH patients undergoing PMV is associated with greater delirium and use of antipsychotics and restraints but does not influence weaning success or LTACH stay. Strategies focused on agitation prevention and treatment in this population need to be developed and formally evaluated. © The Author(s) 2013.

    This paper reports a prospective survey of 173 patients with nonoperable lung cancer between January. 1, 1983 to March. 1, 1985. The follow-up rate was 97.7% over five years. Fourteen factors including sex, age, course of disease before treatment, clinical stage, performance status, size of mass, metastatic status, hemoglobin before treatment, short-term response to treatment and so on which might influence long term survival were studied by univariate analysis (Kruskal-Wallis test for Kaplan-Meier survival curve) and by multivariate analysis (Cox's proportional hazad model and audio-visual chart test for goodness of fit). Multivariate analysis using Cox's model revealed 6 significant prognostic factors: performance status, short-term response to treatment, clinical stage, hemoglobin before treatment, smoking index and method of treatment. The survival prediction equation was chi 2 = 72.14, nu = 6, P < 0.0001. The results indicate that the performance status and the CR rate of the initial treatment, among other things, is the major factors affecting prognosis.

    Background: Preventing pneumonia requires better understanding of incidence, mortality, and long-term clinical and biologic risk factors, particularly in younger individuals. Methods: This was a cohort study in three population-based cohorts of community-dwelling individuals. A derivation cohort (n = 16,260) was used to determine incidence and survival and develop a risk prediction model. The prediction model was validated in two cohorts (n = 8,495). The primary outcome was 10-year risk of pneumonia hospitalization. Results: The crude and age-adjusted incidences of pneumonia were 6.71 and 9.43 cases/1,000 person-years (10-year risk was 6.15%). The 30-day and 1-year mortality were 16.5% and 31.5%. Although age was the most important risk factor (range of crude incidence rates, 1.69-39.13 cases/1,000 person-years for each 5-year increment from 45-85 years), 38% of pneumonia cases occurred in adults < 65 years of age. The 30-day and 1-year mortality were 12.5% and 25.7% in those < 65 years of age. Although most comorbidities were associated with higher risk of pneumonia, reduced lung function was the most important risk factor (relative risk = 6.61 for severe reduction based on FEV1 by spirometry). A clinical risk prediction model based on age, smoking, and lung function predicted 10-year risk (area under curve [AUC] = 0.77 and Hosmer-Lemeshow [HL] C statistic = 0.12). Model discrimination and calibration were similar in the internal validation cohort (AUC = 0.77; HL C statistic, 0.65) but lower in the external validation cohort (AUC = 0.62; HL C statistic, 0.45). The model also calibrated well in blacks and younger adults. C-reactive protein and IL-6 were associated with higher pneumonia risk but did not improve model performance. Conclusions: Pneumonia hospitalization is common and associated with high mortality, even in younger healthy adults. Long-term risk of pneumonia can be predicted in community-dwelling adults with a simple clinical risk prediction model

    The aims of this study were to clarify the long-term outcome of patients with polymyositis and dermatomyositis (PM/DM) and to elucidate prognostic factors using statistical analysis. We enrolled patients with PM/DM who visited our department between 1990 and 2014. Diagnoses of PM/DM and clinically amyopathic DM were based on the definitions of Bohan and Peter, and Sontheimer, respectively. We also obtained clinical data, such as age of onset, sex, medications, and presence of interstitial lung disease and malignancies, as well as laboratory tests, including the values of creatine kinase, KL-6, and ferritin. The follow-up was conducted until June 2014. A total of 124 patients (PM: 46, DM: 78) were enrolled. The mean age of onset was 53.5 years, and females were predominant (64.5%). Overall survival rates were 93%, 86%, and 78% for 1, 5, and 10 years, respectively. The survival rates were significantly lower in patients with higher age of onset, with malignancies, and with hyperferritinemia in univariate analysis; however, multivariate analysis identified age of onset and serum ferritin as the most significant prognostic factors. Our study indicates that when age of onset and serum ferritin are used in combination, we can predict prognosis of patients with PM/DM.

    A considerable number of patients suffer recurrence of scabies. To elucidate risk factors for recurrence of scabies, we compared patients who experienced scabies recurrence and those who suffered scabies only once. We conducted a retrospective review of medical records of all scabies patients in a long-term care hospital for the elderly (300 beds; six wards) for a period of 42 months to determine frequency of scabies onsets, underlying diseases, history of treatment, and demographic data such as age and sex. One hundred and forty-eight patients and five hospital staff members suffered scabies during the 42-month study period. All staff members and 98 patients had no recurrence, while 50 patients experienced at least one recurrence of scabies. The cumulative number of scabies diagnoses was 228. The rates of scabies onset and recurrence were considerably different among wards. The dementia unit showed the highest rate of onset and recurrence. In addition to frequent exposure to infectious sources, problematic behavior, such as lying in other patients beds, might cause the high recurrence rate in dementia units. Higher serum total lymphocyte count and topical use of γ-benzene hexachloride were associated with lower risk of scabies recurrence. Recurrence of scabies is not uncommon among elderly patients in institutional settings. Impaired immunity may be a risk factor for recurrence of scabies. Groups with a high onset rate of scabies pose a high likelihood of recurrence. Problematic behavior of demented patients may increase the risk of recurrence. Use of effective topical treatment may effectively prevent recurrence.

    In this study, we explore the mechanistic relationship between growth factor signaling and kinase activity that supports the protein synthesis-dependent phase of long-term memory (LTM) consolidation for sensitization ofAplysia Specifically, we examine LTM for tail shock-induced sensitization of the tail-elicited siphon withdrawal (T-SW) reflex, a form of memory that requires both (i) extracellular signal-regulated kinase (ERK1/2; MAPK) activity within identified sensory neurons (SNs) that mediate the T-SW and (ii) the activation of transforming growth factor β (TGFβ) signaling. We now report that repeated tail shocks that induce intermediate-term (ITM) and LTM for sensitization, also induce a sustained post-training phase of MAPK activity in SNs (lasting at least 1 h). We identified two mechanistically distinct phases of post-training MAPK: (i) an immediate phase that does not require ongoing protein synthesis or TGFβ signaling, and (ii) a sustained phase that requires both protein synthesis and extracellular TGFβ signaling. We find that LTM consolidation requires sustained MAPK, and is disrupted by inhibitors of protein synthesis and TGFβ signaling during the consolidation window. These results provide strong evidence that TGFβ signaling sustains MAPK activity as an essential mechanistic step for LTM consolidation.

    The aim of this research was to investigate factors affecting different family members' decisions regarding the placement of relatives in long-term car (LTC) facilities in Taiwan. The objective was to investigate the correlations between family members' personal traits, the living conditions of residents in the LTC facilities, and family members' experiences with LTC facilities. This study selected family members visiting residents in LTC facilities as research subjects and used a structured questionnaire to perform face-to-face interviews. This study used nonlinear canonical correlation analysis (OVERALS) to categorize the decision-making factors affecting family members' choices of LTC facilities. The results showed that when making decisions about the placement of family members, spouses chose facilities according to their own life experiences, children considered medical treatment convenience, grandchildren preferred to collect relevant information on facilities, and other relatives preferred to decide based on introductions from government departments. These results help clarify how different family roles affect decision-making processes regarding the choice of LTC facilities. In particular, spouses and female relatives require an interventional service mechanism that provides consultation or referral information.

    Sea lice (Copepoda: Caligidae) are marine copepods that parasitize finfish, and in cases of high infestation can result in severe epithelial damage and mortality. In Scotland, 2 species of sea louse, Lepeophtheirus salmonis and Caligus elongatus, pose a significant economic burden to the marine Atlantic salmon aquaculture industry and potentially impact wild salmonids. The purpose of this study was to determine how the density of pelagic sea lice is affected by external variables, in order to improve our understanding of sea lice dynamics. Long-term data from 2 sampling sites on the east and west coasts of Scotland were modelled independently in conjunction with environmental and anthropogenic variables. Statistical analysis identified that at the east coast site, the most influential factor affecting lice density was salinity. On the west coast, salinity, rainfall and farmed salmon production year were most influential. Molecular and morphological techniques also showed that the individuals recorded on the east coast were C. elongatus, a generalist copepod parasite, whereas only the salmonid-specific L. salmonis were found on the west. These results reiterate the role of environmental factors in influencing sea lice dynamics, and that salmonids are the primary hosts of sea lice on the west coast, but there could be non-salmonid host species as well as salmonid species influencing east coast sea lice densities.

    We sought to determine risk factors associated with fetal macrosomia and to explore the long-term consequence of infant macrosomia at the age of 7 years. A prospective population based cohort study was designed to examine the associations between maternal and perinatal characteristics and the risk of macrosomia. A nested case-control study was conducted to explore the long-term health consequence of infant macrosomia. The mean maternal age of the macrosomia group was 24.74±3.32 years, which is slightly older than that in the control group (24.35±3.14 years, P = 0.000). The mean maternal body mass index (BMI) at early pregnancy was 22.75±2.81 kg/m2, which was also higher than that in the control group (21.76±2.59 kg/m2, P = 0.000). About 64.6% of macrosomic neonates were males, compared with 51.0% in the control group (P = 0.000). Compared with women with normal weight (BMI: 18.5-23.9 kg/m2), women who were overweight (BMI: 24-27.9 kg/m2) or obese (BMI≥28 kg/m2), respectively, had a 1.69-fold (P = 0.000) and a 1.49-fold (P = 0.000) increased risks of having a neonate with macrosomia, while light weight (BMI<18.5 kg/m2) women had an approximately 50% reduction of the risk. Furthermore, macrosomia infant had a 1.52-fold and 1.50-fold risk, respectively, of developing overweight or obesity at the age of 7 years (P = 0.001 and P = 0.000). Older maternal age, higher maternal BMI at early pregnancy and male gender were independent risk factors of macrosomia. Macrosomic infant was associated with an increased predisposition to develop overweight or obesity at the beginning of their childhood. PMID:23554754

    Antiepileptic drugs (AED) have potential side effects through vitamin-D. Prevalence of vitamin D insufficiency and potential risk factors for the longitudinal changes of vitamin D levels compared to its baseline levels under AED treatment were investigated in this study. This retrospective study includes patients whose AED therapy were started in only autumn months, between 2000 and 2014. Detailed assessment of neurologic diagnosis and brain MRI findings, ambulatory status, types and durations of AED treatment, and baseline bone health blood tests (vitamin-D, alkaline phosphatase, calcium, and phosphate levels) were obtained on all patients. Vitamin-D deficiency was defined as 25(OH)D <20 ng/mL, while vitamin-D insufficiency was defined as 25(OH)D between 21 and 29 ng/mL. A total of 172 children (mean age 9.6 ± 4.3 years) were followed up 5.3 years in average (range 1-14.7). The mean baseline 25(OH)D level was decreased from 24.4 ± 11.6 to 19.6 ± 10.7 ng/mL at the last follow up. The mean change in the vitamin-D levels (ΔD-vitamin) was -4.8 ng/mL (p = 0.003). The rate of vitamin-D deficiency was 54% and insufficiency was 25%. Multivariate logistic regression analysis identified only long-term use of AEDs as a risk factor for the longitudinal decrease. Monotherapy with valproic acid (n = 45), carbamazepine (n = 20), levetiracetam (n = 10) and phenobarbital (n = 12) was compared with each other. There was no difference in terms of longitudinal changes in 25(OH)D levels. In the treatment of childhood epilepsy, 25(OH)D levels should be monitored, especially when long-term AED used, in order to prevent D-hypovitaminosis.

    Influenza in long-term care facilities is an ever more challenging problem. Vaccination of residents and health care workers is the most important preventive measure. Although vaccine efficacy has been questioned, the preponderance of data favors vaccination. Antiviral resistance complicates postexposure chemoprophylaxis and treatment. Factors that limit the choice of antiviral agents in this patient population include limited vaccine supplies and impaired dexterity and confusion in long-term care residents.

    Abstract Family problem-solving therapy (FPST) has been shown to reduce behavior problems after pediatric traumatic brain injury (TBI). It is unclear whether treatment gains are maintained. We sought to evaluate the maintenance of improvements in behavior problems after a Web-based counselor-assisted FPST (CAPS) intervention compared to an Internet resource comparison (IRC) intervention provided to adolescents within the initial year post-TBI. We hypothesized that family socioeconomic status, child educational status, and baseline levels of symptoms would moderate the efficacy of the treatment over time. Participants included 132 adolescents ages 12–17 years who sustained a complicated mild-to-severe TBI 1–6 months before study enrollment. Primary outcomes were the Child Behavior Checklist Internalizing and Externalizing Totals. Mixed-models analyses, using random intercepts and slopes, were conducted to examine group differences over time. There was a significant group×time×grade interaction (F(1,304)=4.42; p=0.03) for internalizing problems, with high school–age participants in CAPS reporting significantly lower symptoms at 18 months postbaseline than those in the IRC. Post-hoc analyses to elucidate the nature of effects on internalizing problems revealed significant group×time×grade interactions for the anxious/depressed (p=0.03) and somatic complaints subscales (p=0.04). Results also indicated significant improvement over time for CAPS participants who reported elevated externalizing behavior problems at baseline (F(1, 310)=7.17; p=0.008). Findings suggest that CAPS may lead to long-term improvements in behavior problems among older adolescents and those with pretreatment symptoms. PMID:25738891

    Risk factors in oral implantology are defined as local or systemic conditions that increase failure rates. The purpose of this paper is to evaluate the long-term survival rate of dental implants placed in patients presenting mechanical risk factors. This retrospective study was conducted only with patients presenting at least one of the following risk factors were included: Bruxism; crown-to-implant (C/I) ratio <0.8; abutment angulation. The overall implant survival was estimated using Kaplan-Meier analyses. Risk factors for implant failure were identified using the Cox proportional hazard regression models. Eighty-nine eligible patients were enrolled in this study: They were both male (n = 56, 62.92%) and female (n = 33, 37.08%), with an average age of 53.24 (23-76 years), with 227 dental implants inserted. The mean follow-up was 13.6 years (range: 10-16 years). The overall 10-year Kaplan-Meier survival estimate with associated 95% confidence intervals was 86.34% (82.8, 87.1). Bruxism was the only variable that showed a statistically significant association with implant failure (P < 0.05) and a hazard ratio of 2.9, while both Crown to-implant and abutment angulations reported lower values of failure (P > 0.05). Within the limitations of this study, can be concluded that data suggested an evident relationship between bruxism and dental implant failure but further studies, with a larger sample and a different design are required to assess this relationship.

    Purpose To report on the long-term outcomes and risk factors for failure with the EX-PRESS shunt implanted under a scleral flap. Settings Eye Department, University of Ancona, Ancona, Italy and the Oxford Eye Center, University of Witwatersrand, Johannesburg, South Africa. Methods The medical records of glaucoma patients who underwent consecutive EX-PRESS implantations under a scleral flap between 2000 and 2009 were reviewed. The operations were performed by two experienced surgeons using an identical surgical technique. The potential risk factors for failure that were analysed included age, sex, race, glaucoma type, previous antiglaucoma medications, previous glaucoma surgeries, diabetes, and smoking. Complete success was defined as postoperative intraocular pressure (IOP) 5 mm Hg>IOP<18 mm Hg without antiglaucoma medications. Qualified success was defined as 5 mm Hg>IOP<18 mm Hg with or without antiglaucoma medications. Results Two hundred and forty-eight eyes of 211 consecutive patients were included. The mean IOP was reduced from 27.63±8.26 mm Hg preoperatively (n=248) to 13.95±2.70 mm Hg at 5 years (n=95). The mean follow-up was 3.46±1.76 years. Complete and qualified success rates decreased gradually from 83% and 85% at 1 year to 57% and 63% at 5 years follow-up, respectively. The risk factors for failure were diabetes, non-Caucasian race, and previous glaucoma surgery. Complete success rates of diabetic patients and non-Caucasian patients decreased from 63% and 75% at 1 year to 42% and 40% at 5 years follow-up, respectively. Conclusions EX-PRESS success rates decrease over time but compare favourably with trabeculectomy literature data. The main identifiable risk factors for failure are diabetes, non-Caucasian race, and previous glaucoma surgery. PMID:24232313

    The purpose of the study was to evaluate the long-term anatomical and functional outcomes in patients with retinal vein occlusion (RVO), either central retinal vein occlusion or branch retinal vein occlusion, treated with intravitreal ranibizumab and to determine the predictive factors of the final visual outcome. This retrospective study included 54 treatment-naive patients with macular edema due to RVO (25 with central retinal vein occlusion and 29 with branch retinal vein occlusion), who were treated with intravitreal ranibizumab (3 monthly injections and pro re nata). Predictive factors for visual outcome were assessed. In addition, the best-corrected visual acuity change and the percentage of patients with edema resolution were evaluated. The mean follow-up time was 47.4 ± 11.1 months. At the end of the follow-up, patients with central retinal vein occlusion gained +6.9 letters (∼1 Snellen line), whereas patients with branch retinal vein occlusion gained +15.1 letters (3 Snellen lines). Forty-eight percent of patients in central retinal vein occlusion group and 69.0% in branch retinal vein occlusion group presented resolution of macular edema. Negative predictive factors for the final visual outcome were found to be increasing age, increasing macular thickness, the presence of intraretinal fluid, the duration of RVO >3 months, the ischemic type of RVO, the cystoid type of edema, and the external limiting membrane and ellipsoid zone disruption. The various predictive factors that determine the visual outcome and possibly define the patients' prognosis after ranibizumab treatment in RVO have been studied. The long follow-up period showed that ranibizumab seems to be safe and effective in the treatment of the disease.

    Obesity is a multifactorial syndrome and the likelihood of success of a medical nutritional treatment (MNT) over the long term is low. As psychological and behavioural factors have an important role in both pathogenesis and the treatment of obesity, these issues were investigated in individuals with obesity who reported a long-term success or a failure in terms of weight loss following a MNT. Eighty-eight individuals of an original cohort of 251 subjects were re-evaluated 10 years after a MNT with cognitive-behavioural approach for uncomplicated obesity. Fifty-three participants were classified as failure (body weight change ≥0.5 kg) and 35 as a success (10-year body weight change <0.5 kg) of the MNT. Prior to the beginning of the weight-management program, both the Dieting Readiness Test (DRT) and the Hospital Anxiety and Depression Scale (HADS) were administered. At a 10-year follow-up after the MNT, self-reported questionnaires were administered: quality of life was assessed by the Obesity Related Well-Being (ORWELL 97) questionnaire, eating attitudes and behaviours by the Eating Disorder Examination Questionnaire (EDE-Q), the Binge Eating Scale (BES) investigated the presence and severity of binge eating and the Symptom Checklist (SCL 90-R) was used to identify the psychopathological distress. The scores of the ORWELL 97 items concerning symptoms (P = 0.005), discomfort (P = 0.03) and the total score (P = 0.02) were significantly lower in the success group. The depression score of the HADS was positively correlated with the percentage of body weight change observed 10 years after the MNT (r = 0.22; P = 0.045). The scores of the shape concern (EDE-Q) (r = 0.35; P = 0.013) and of the discomfort (ORWELL 97) (r = 0.36; P = 0.012) were significantly correlated with the percentage of body weight change 10 years after the MNT. In conclusion, this study is in agreement with the possibility that the psychological quality of life is associated even with modest amounts

    Background and Objectives Encapsulating peritoneal sclerosis (EPS) is a rare but serious and life-threatening complication of peritoneal dialysis (PD). However, the precise pathogenesis remains unclear; in addition, predictors and early diagnostic biomarkers for EPS have not yet to be established. Methods Eighty-three peritoneal membrane samples taken at catheter removal were examined to identify pathological characteristics of chronic peritoneal deterioration, which promotes EPS in patients undergoing long-term PD treatment with low occurrence of peritonitis. Results According to univariable logistic regression analysis of the pathological findings, thickness of the peritoneal membrane (P = 0.045), new membrane formation score (P = 0.006), ratio of luminal diameter to vessel diameter (L/V ratio, P<0.001), presence of CD31-negative vessels (P = 0.021), fibrin deposition (P<0.001), and collagen volume fraction (P = 0.018) were associated with EPS development. In analyses of samples with and without EPS matched for PD treatment period, non-diabetes, and PD solution, univariable analysis identified L/V ratio (per 0.1 increase: odds ratio (OR) 0.44, P = 0.003) and fibrin deposition (OR 6.35, P = 0.027) as the factors associated with EPS. L/V ratio was lower in patients with fibrin exudation than in patients without fibrin exudation. Conclusions These findings suggest that damage to vascular endothelial cells, as represented by low L/V ratio, could be a predictive finding for the development of EPS, particularly in long-term PD patients unaffected by peritonitis.

    To examine risk factors associated with head impact during falls in older adults in long-term care (LTC). Two LTC facilities in British Columbia, Canada. 160 LTC residents. Prospective cohort study. Between 2007 and 2014, we video captured 520 falls experienced by participants. Each fall video was analyzed to determine whether impact occurred to the head. Using generalized estimating equation models, we examined how head impact was associated with other fall characteristics and health status prior to the fall. Head impact occurred in 33% of falls. Individuals with mild cognitive impairment were at higher risk for head impact (odds ratio = 2.8; 95% confidence interval, 1.5-5.0) than those with more severe cognitive impairment. Impaired vision was associated with 2.0-fold (1.3-3.0) higher odds of head impact. Women were 2.2 times (1.4-3.3) more likely than men to impact their head during a fall. Head impact is common during falls in LTC, with less cognitively impaired, female residents who suffered from visual impairment, being most likely to impact their head. Future research should focus on improving our ability to detect neural consequences of head impact and evaluating the effect of interventions for reducing the risk for fall-related head injuries in LTC.

    In this study we demonstrated that neural rosettes derived from human ES cells can give rise either to neural crest precursors, following expansion in presence of bFGF and EGF, or to dopaminergic precursors after exposure to ventralizing factors Shh and FGF8. Both regionalised precursors are capable of extensive proliferation and differentiation towards the corresponding terminally differentiated cell types. In particular, peripheral neurons, cartilage, bone, smooth muscle cells and also pigmented cells were obtained from neural crest precursors while tyrosine hydroxylase and Nurr1 positive dopaminergic neurons were derived from FGF8 and Shh primed rosette cells. Gene expression and immunocytochemistry analyses confirmed the expression of dorsal and neural crest genes such as Sox10, Slug, p75, FoxD3, Pax7 in neural precursors from bFGF-EGF exposed rosettes. By contrast, priming of rosettes with FGF8 and Shh induced the expression of dopaminergic markers Engrailed1, Pax2, Pitx3, floor plate marker FoxA2 and radial glia markers Blbp and Glast, the latter in agreement with the origin of dopaminergic precursors from floor plate radial glia. Moreover, in vivo transplant of proliferating Shh/FGF8 primed precursors in parkinsonian rats demonstrated engraftment and terminal dopaminergic differentiation. In conclusion, we demonstrated the derivation of long-term self-renewing precursors of selected regional identity as potential cell reservoirs for cell therapy applications, such as CNS degenerative diseases, or for the development of toxicological tests.

  19. Distinct Growth Factor Families Are Recruited in Unique Spatiotemporal Domains during Long-Term Memory Formation in Aplysia californica.

    Several growth factors (GFs) have been implicated in long-term memory (LTM), but no single GF can support all of the plastic changes that occur during memory formation. Because GFs engage highly convergent signaling cascades that often mediate similar functional outcomes, the relative contribution of any particular GF to LTM is difficult to ascertain. To explore this question, we determined the unique contribution of distinct GF families (signaling via TrkB and TGF-βr-II) to LTM formation in Aplysia. We demonstrate that TrkB and TGF-βr-II signaling are differentially recruited during two-trial training in both time (by trial 1 or 2, respectively) and space (in distinct subcellular compartments). These GFs independently regulate MAPK activation and synergistically regulate gene expression. We also show that trial 1 TrkB and trial 2 TGF-βr-II signaling are required for LTM formation. These data support the view that GFs engaged in LTM formation are interactive components of a complex molecular network.

    Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-κB in memory. This was initially demonstrated in the crab Chasmagnathus model of associative contextual memory, in which re-exposure to the training context induces a well characterized reconsolidation process. Here we studied the role of NF-κB in reconsolidation. NF-κB was specifically activated in trained animals re-exposed to the training context but not to a different context. NF-κB was not activated when animals were re-exposed to the context after a weak training protocol insufficient to induce long-term memory. A specific inhibitor of the NF-κB pathway, sulfasalazine, impaired reconsolidation when administered 20 min before re-exposure to the training context but was not effective when a different context was used. These findings indicate for the first time that NF-κB is activated specifically by retrieval and that this activation is required for memory reconsolidation, supporting the view that this molecular mechanism is required in both consolidation and reconsolidation.

    To evaluate the radiological impact of potential releases to the biosphere from a geological repository for spent nuclear fuel, it is necessary to assess the long-term dynamics of the distribution of radionuclides in the environment. In this paper, we propose an approach for making prognoses of the distribution and fluxes of radionuclides released from the geosphere, in discharges of contaminated groundwater, to an evolving landscape. The biosphere changes during the temperate part (spanning approximately 20,000 years) of an interglacial period are handled by building biosphere models for the projected succession of situations. Radionuclide transport in the landscape is modeled dynamically with a series of interconnected radioecological models of those ecosystem types (sea, lake, running water, mire, agricultural land and forest) that occur at present, and are projected to occur in the future, in a candidate area for a geological repository in Sweden. The transformation between ecosystems is modeled as discrete events occurring every thousand years by substituting one model by another. Examples of predictions of the radionuclide distribution in the landscape are presented for several scenarios with discharge locations varying in time and space. The article also outlines an approach for estimating the exposure of man resulting from all possible reasonable uses of a potentially contaminated landscape, which was used for derivation of Landscape Dose Factors.

    To explore the factors associated with delayed defecation in long-term ventilated patients in intensive care unit (ICU) and their potential effect on prognosis. A prospective observational cohort study was conducted. The patients admitted to general ICU of the Affiliated Hospital of Qingdao University from October 1st in 2013 to September 30th in 2015 who underwent mechanical ventilation (MV) for ≥6 days were enrolled, and they were divided into early defecation group (< 6 days) and late defecation group (≥6 days). At admission, clinical nutritional support were given as usual, and gender, age, acute physiology and chronic health evaluation II (APACHEII) score, admission reasons, MV reasons, the usage of morphine and epinephrine/norepinephrine, the highest positive end-expiratory pressure (PEEP), the lowest oxygenation index (PaO2/FiO2) and the lowest systolic blood pressure were collected. Logistic regression analysis was used to analyze the influencing factors of the first defecation time. ICU mortality, the length of ICU stay, central venous catheter (CVC) indwelling time, duration of MV, ICU acquired bacterial infection rate, and the incidence of ventilator associated pneumonia (VAP) were compared between early defecation group and late defecation group. Logistic organ dysfunction system (LOD) scores and gastric residual volume per day were recorded at the different time of MV. Totally 189 patients were enrolled, 39 patients did not satisfied the inclusion criteria and 13 patients gave up treatment or referrals were excluded. Finally 137 patients were enrolled in the analysis, 83 patients in late defecation group and 54 in early defecation group. There were no significant differences in the baseline characteristics such as gender, age, APACHE II score, LOD score at 1 day of MV, admission reasons, MV reasons, disgorging and gastric residual volume per day during the first 5 days of MV, enteral nutrition, lactulose treatment in patients with hepatic

    To describe factors associated with the utilization of dental services in a long-term care facility (LTCF) in Western New York. A descriptive cross-sectional study reviewed the dental and medical records of residents of an LTCF discharged between January 1, 2008 and December 30, 2012. Information on demographic and health variables at admission was extracted from electronic health records. Information on oral health variables was extracted from patient charts. A total of 2,516 residents were discharged between 2008 and 2012. From those, 259 (10.3%) utilized dental services at least once during their stay. Those who utilized dental services were significantly older at admission (78.5 vs. 82.0 years, p < 0.001), stayed longer (1.6 vs. 3.9 years, p < 0.001), more likely to be female (63.6 vs. 75.6%, p = 0.008), and less likely to be married (37.7 vs. 14.0%, p = < 0.001) compared to those who did not. Patients with endocrine, nutritional, metabolic, and immunity disorders, mental disorders, and circulatory system diseases were more likely to receive dental services. Dental services appear to be underutilized by residents of LTCF. Significant differences exist in demographic and health variables between residents who utilize these services compared to those who do not. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

    We carried out a survival analysis of elbow synovectomy (ES) and excision of the radial head (RHE) performed on 171 rheumatoid elbows. The failure criteria were revision surgery (performed or desired) and/or the presence of significant or severe pain. The cumulative survival was 81% at one year which thereafter decreased by an average of 2.6% per year. The strongest predictor for success was a low preoperative range of supination-pronation when corresponding survival curves were compared. A low range of flexion-extension also predicted failure. Combining both factors gave better prediction (failure: 6.3% v 67%), but a long duration of elbow symptoms before surgery predicted failure (72%, p = 0.04). At review, there was a mean gain of 50 degrees in supination-pronation and 11 degrees in flexion-extension; both correlated with success. Failure correlated with recurrence of synovitis, elbow instability, ulnar neuropathy, poor general mobility and poor upper-limb function. The last was independently affected by the severity of RA in the ipsilateral shoulder. Our findings show that although the short-term result of ES and RHE in rheumatoid arthritis is good, the long-term outcome is poor except in a subgroup with more than 50% limitation of forearm rotation.

    Long-term outcomes of seizures that develop during treatment of childhood hematological malignancies have not been described. We analyzed seizure outcome in 62 children with leukemia or lymphoma treated at our institution. There was a median follow-up of 6.5 years since first seizure. Seizure etiology included intrathecal or systemic methotrexate in 24, leucoencephalopathy in 11, brain hemorrhage or thrombosis in 11, meningitis in 4, and no identifiable cause in 12. Seizures remained uncontrolled in 18, and risk factors for poor control included female sex (P = .02), no seizure control with first antiseizure drug (P = .08), and longer interval between cancer diagnosis and seizure onset (P = .09). Poor seizure control after initial antiseizure drug also predicted recurrent seizure after drug withdrawal (P = .04). In conclusion, seizures are controlled with medications in a majority of patients with hematological cancer. After a period without seizures, antiseizure drug withdrawal in appropriately selected patient has a high success rate. © The Author(s) 2013.

    To the authors' knowledge, the incidence of late recurrence (> 5 years after initial management) is unknown and no prognostic factors for late events have been characterized in patients with soft tissue sarcomas. Follow-up data from patients with localized soft tissue sarcoma who were included in the French Sarcoma Group database from January 1990 to June 2005 were reviewed. The outcomes of interest were the cumulative probabilities of late (> 5 years) local and metastatic disease recurrence with death as a competing event. Estimations and 95% confidence intervals (95% CIs) were computed with the cumulative incidence function. A total of 719 patients who were alive and event free > 5 years after their initial diagnosis were included in the current study. Sixty-seven patients (9.3%) developed a late local recurrence and 42 patients (5.8%) developed a late metastatic recurrence, respectively. On multivariate analysis, internal trunk location (hazard ratio [HR], 3.9; 95% CI, 2.2-6.7 [P < .001]) and tumor size > 100 mm (HR, 2.1; 95% CI, 1.1-4 [P = .035]) were the 2 factors found to be independently associated with an increased risk of late local recurrence. Grade > 1 (graded according to the French Federation of Cancer Centers Sarcoma Group) (HR, 4.7; 95% CI 1.1-21 [P = .04]) was the sole factor found to be independently associated with an increased risk of late metastatic recurrence. Late recurrence of soft tissue sarcoma is relatively uncommon. However, the results of the current study emphasize the critical role of long-term follow-up to detect late local disease recurrence in patients with retroperitoneal or very large soft tissue sarcomas, and late metastatic recurrence in patients with high-grade disease. Conversely, the prolonged follow-up of patients with grade 1 disease is not needed. © 2014 American Cancer Society.

    Observations from the Mercury Deposition Network (MDN) at Huntington Wildlife Forest (HWF) suggested that a significant decline (r2 = 0.34, p = 0.03) from 2000 to 2013 in volume weighted mean (VWM) Hg concentrations in precipitation was linked to Hg emission decreases in the United States, especially in the Northeast and Midwest, and yet Hg wet deposition has remained fairly constant over the past two decades. The present study aimed to investigate the climatic, terrestrial, and anthropogenic factors that influenced the decadal pattern in Hg wet deposition in upstate NY. In spring and summer, when Hg wet deposition was the strongest, significant positive correlation (r2 = 0.89, p < 0.0001 in spring; r2 = 0.58, p = 0.002 in summer) of Hg wet deposition with precipitation was found. Increases in precipitation during these seasons could offset the decreasing of Hg concentration in precipitation. Besides, springtime positive correlation (r2 = 0.35, p = 0.02) between precipitation and the North Atlantic Oscillation (NAO) index together with geopotential height and wind speed analysis indicated that large-scale dynamical forcing was likely an important factor influencing the long term trend in springtime Hg wet deposition at HWF. To further quantify the roles of meteorological and anthropogenic factors in Hg wet deposition, the Community Multiscale Air Quality (CMAQ) model was employed using an algorithm depicting state-of-the-art Hg chemistry mechanism and up-to-date Hg emission inventories evaluated with MDN and Atmospheric Mercury Network (AMNet) measurement data. CMAQ simulations with a constant vs. realistic meteorological conditions for multiple warm seasons (including spring and summer) were used to characterize and quantify the impacts of inter-annual variability of precipitation and atmospheric circulation on Hg wet deposition. In addition, contributions to Hg wet deposition from decreases in anthropogenic emissions in NYS and nation-wide were quantified from

    The aim of the present study was to investigate the correlation between plasma the levels of vascular endothelial growth factor (VEGF) and major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI). A total of 124 patients with AMI undergoing emergency percutaneous coronary intervention (PCI) were selected, and plasma VEGF levels were measured 7 days after the onset of AMI using an enzyme-linked immunosorbent assay. The patients were divided into the L (≤190 pg/ml VEGF) and H (>190 pg/ml VEGF) groups, and were followed up every 2 months for an average of 12 months. MACE were recorded during follow-up. On the basis of these results, the patients were further divided into the MACE and non-MACE (N-MACE) groups, and the serum VEGF concentration was compared between the two groups. At the 6-month follow-up, the incidence of MACE in the H group was found to be significantly reduced compared with the L group. The serum VEGF concentration in the N-MACE group was significantly higher compared with the MACE group. Multinomial logistic regression revealed that reduced VEGF levels (β=1.243; 95% CI, 1.018–1.326; P=0.026) were independent risk factors for MACE. In conclusion, high plasma VEGF levels at 7 days after AMI onset facilitate the long-term prognosis in the same infarct zone in patients with AMI, while low plasma VEGF levels are independent risk factors for MACE.

    Cardiovascular-related mortality is 100-fold higher in pediatric renal transplant recipients than in the age-matched general population. Seventy-seven post-renal transplant children's charts were reviewed for cardiovascular risk factors at two and six months after transplantation (short term) and at two yr after transplantation and the last follow-up visit (mean 7.14 ± 3.5 yr) (long term). Significant reduction was seen in cardiovascular risk factors prevalence from two months after transplantation to last follow-up respectively: Hypertension from 52.1% to 14%, hypercholesterolemia from 48.7% to 33%, hypertriglyceridemia from 50% to 12.5%, anemia from 29.6% to 18.3%, hyperparathyroidism from 32% to 18.3% and hyperglycemia from 11.7% to 10%, and left ventricular hypertrophy from 25.8% at short term to 15%. There was an increase in the prevalence of obesity from 1.5% to 3.9% and of CKD 3-5 from 4.75% to 24%. The need for antihypertensive treatment decreased from 54% to 42%, and the percentage of patients controlled by one medication rose from 26% to 34%, whereas the percentage controlled by 2, 3, and 4 medications decreased from 21.9%, 5.5%, and 1.4% to 6%, 2%, and 0. Children after renal transplantation appear to have high rates of cardiovascular risk factors, mainly on short-term follow-up. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To investigate the long-term outcome and prognostic factors when treating hepatocellular carcinoma (HCC) with thermal ablation. A total of 846 HCC patients, diagnosed histopathologically and/or radiologically, underwent thermal ablation from October 2001 to May 2013. Thermal ablation included both radiofrequency ablation (RFA) and microwave ablation (MWA), and was performed by percutaneous, open, and laparoscopic approaches. Clinical data, especially focused on disease-free survival, were retrospectively analysed by univariate and multivariate analyses. A total of 1,185 thermal ablation treatments were performed, corresponding to 1,240 tumours. The complete ablation rate was 97.1%. The 12-, 24-, 36-, and 60-month disease-free survival rates after thermal ablation were 72.3%, 52.7%, 33.5%, and 16.1%, respectively. Multivariate analysis indicated that the serum alkaline phosphatase levels (ALP) and the number of tumours were independent risk factors affecting disease-free survival. The 12-, 36-, 60-, 84-, and 120-month overall survival rates of all patients were 92.9%, 74.7%, 58.1%, 41.3%, and 15.8%, respectively. Multivariate analysis indicated that age, ALP, number of tumours, and treatment sessions per case were independent risk factors related to overall survival. Thermal ablation was a relatively safe and effective procedure. Patients with increased serum ALP levels and/or multiple tumours had a higher incidence of recurrence and poorer prognosis, and therefore, should be monitored closely in clinical practice.

    Identification of caregiver risk factors associated with psychological elder abuse is crucial for preventing and managing such abuse. The aim of this study was to test the most effective model for explaining caregiver factors contributing to caregiver psychological abuse behavior. We hypothesized that caregiver hours worked each day, years of education, age, geriatric care-giving training, gerontological care knowledge, social resources, and self-reported work stress are factors contributing to psychological abuse behavior of caregivers. A cross-sectional study design was used. The sample included a total of 183 caregivers recruited from seven long-term care facilities in southern areas of Taiwan. Instruments included the Caregiver Psychological Elder Abuse Behavior (CPEAB) scale, the Work Stressors Inventory Chinese version (WSI-C), the Personal Resources Questionnaire (PRQ-2000), and Knowledge of Gerontological Nursing Scale (KGNS). The structural equation modeling (SEM) procedure was used to analyze the data. All the model-fit indexes (chi2 = 87.84, df = 70, p = 0.073; CMIN/DF = 1.26; GFI = 0.94, AGFI =0.91, TLI = 0.96, RMSEA = 0.037) of the final model exceeded their respective common acceptance levels except for the normed fit index (NFI) value (0.88). The study results suggest that caregivers who work fewer hours, received fewer years of education, lack social resources, and had more work stress showed higher levels of psychological abuse behavior in caring for the elderly (p = 0.000-0.037). These findings should be incorporated into practice by intervening to reduce caregiver stress and reduce elder abuse behaviors. To help reduce elder psychological abuse, caregivers would benefit from stress management and social resource interventions provided by employers or government programs.

    IL2 infusion may benefit patients with haematological malignancies by lowering the disease burden. However, conflicting data have been reported on IL2 effects on myelopoiesis, in vitro as well as in vivo. In the present study we investigated the ability of IL2 to act on committed and primitive bone marrow progenitor cells in defined serum-free (SF) culture conditions which avoid many technical biases such as interference by exogenous stimulating or inhibiting factors. Low doses of IL2 (0.1-1000 U/ml) were studied without or in combination with recombinant IL3, GM-CSF and erythropoietin, in SF long-term marrow culture (LTMC). We report data in favour of an inhibitory activity of IL2 limited to committed progenitors and excluding more primitive haemopoietic stem cells, as shown by an alteration of CFU-GM proliferation during the first 5 weeks of LTMC, decreasing with time, unaffected BFU-E and increased nucleated cell production. Beyond week 5, no difference was observed between IL2 supplemented cultures and the SF control cultures. In parallel, IL2 induced the adherence of fibroblastic cells and their progeny. In addition to the inhibitory effect, IL2 appeared to limit the stimulating effect on granulopoiesis and erythropoiesis of myeloid growth factors (GF) such as combination of IL3, GM-CSF and EPO. Indeed, in SF-LTMC conditions, IL2 inhibitory effect is effective on CFU-GM production throughout the 7 weeks of LTMC and on BFU-E during the first 2 weeks only. These data confirm the interaction of IL2 with other GFs in the complex interplay of the cytokine network.

    Abstract Anastomotic leakage (AL) is a well-known cause of morbidity after low anterior resection (LAR) for rectal cancer, but its impact on oncologic outcome is not well understood. The aim of this study is to investigate the impact of AL on long-term oncologic outcome and to identify factors associated with AL that may affect prognosis after LAR for rectal cancer. A retrospective analysis of patients who underwent curative resection for rectal cancer without diverting stoma was performed. To investigate AL related factors that may be associated with oncologic outcome, Clavien-Dindo grades, prognostic nutritional indices (PNI) and inflammatory indices were included. One hundred and one patients out of a total of 1258 patients developed postoperative AL, giving an AL rate of 8.0%. Patients with AL showed poorer disease-free survival (DFS), than patients without AL (hazard ratio [HR] = 1.6; 95% confidence intervals [CI]: 1.1–2.5; P = 0.01). In patients who developed AL, age over 60 (HR = 2.2; 95% CI: 1.1–4.7; P = 0.033), advanced pathologic stage (HR = 2.4; 95% CI: 1.4–4.0; P = 0.001), suppressed neutrophil-proportion (≤80%) (HR = 2.6; 95% CI: 1.2–5.8; P = 0.019) and PNI <36 (HR = 3.5; 95% CI: 1.2–9.6; P = 0.018) were associated with poorer DFS. AL was associated with poorer DFS. In patients with AL, a suppressed neutrophil-proportion and decreased PNI below 36 were associated with tumor recurrence. PMID:27472726

    This retrospective, single-center, observational study on postoperative long-term results aims to define yet unknown factors for long-term outcome after operation for chronic pancreatitis. We analyzed 147 consecutive patients operated for chronic pancreatitis from 2000 to 2011. Mean follow-up was 5.3 years (range, 1 month to 12.7 years). Complete long-term survival data were provided by the German citizen registration authorities for all patients. A quality-of-life questionnaire was sent to surviving patients after a mean follow-up of 5.7 years. Surgical principles were resection (n = 86; 59%), decompression (n = 29; 20%), and hybrid procedures (n = 32; 21%). No significant influences of different surgical principles and operative procedures on survival, long-term quality of life and pain control could be detected. Overall 30-day mortality was 2.7%, 1-year survival 95.9%, and 3-year survival 90.8%. Multivariate Cox regression analysis revealed that only postoperative insulin dependence at the time of hospital discharge (P = .027; Exp(B) = 2.111; 95% confidence interval [CI], 1.089-4.090) and the absence of pancreas enzyme replacement therapy at the time of hospital discharge (P = .039; Exp(B) = 2.102; 95% CI, 1.037-4.262) were significant, independent risk factors for survival with significant hazard ratios for long-term survival. Long-term improvement in quality of life was reported by 55 of 76 long-term survivors (73%). Pancreatic enzyme replacement should be standard treatment after surgery for chronic pancreatitis at the time of hospital discharge, even when no clinical signs of exocrine pancreatic failure exist. This study underlines the potential importance of early operative intervention in chronic pancreatitis before irreversible endocrine dysfunction is present. Copyright © 2014 Mosby, Inc.

    Weight loss after bariatric surgery varies, yet preoperative clinical factors associated with long-term suboptimal outcomes are not well understood. To evaluate the association between preoperative clinical factors and long-term weight loss after Roux-en-Y gastric bypass (RYGB). From June 2001 to September 2007, this retrospective cohort study followed up RYGB patients before surgery to 7 to 12 years after surgery. The setting was a large rural integrated health system. Of 1033 eligible RYGB patients who consented to participate in longitudinal research and completed surgery before October 2007, a total of 726 (70.3%) had a weight entered in the electronic medical record 7 or more years after surgery and were included in the analyses after exclusions for pregnancy and mortality. Date of the long-term weight measurement was recorded between August 2010 and January 2016. The primary outcome was percentage weight loss (%WL) at 7 to 12 years after surgery. Preoperative clinical factors (>200) extracted from the electronic medical record included medications, comorbidities, laboratory test results, and demographics, among others. Among the 726 study participants, 83.1% (n = 603) were female and 97.4% (n = 707) were of white race, with a mean (SD) preoperative body mass index (calculated as weight in kilograms divided by height in meters squared) of 47.5 (7.4). From the time of surgery to long-term follow-up (median, 9.3 postoperative years), the mean (SD) %WL was 22.5% (13.1%). Preoperative insulin use, history of smoking, and use of 12 or more medications before surgery were associated with greater long-term postoperative %WL (6.8%, 2.8%, and 3.1%, respectively). Preoperative hyperlipidemia, older age, and higher body mass index were associated with poorer long-term postoperative %WL (-2.8%, -8.8%, and -4.1%, respectively). Few preoperative clinical factors associated with long-term weight loss after RYGB were identified. Preoperative insulin use was strongly

    The long-term results with large fenestra stapedectomy with vein graft and Teflon piston are compared with results with the small fenestra stapedectomy with teflon piston directly into the vestibule. There were 1,943 operations in the former group and 2,155 in the latter when compared in 1970. One hundred consecutive patients from the beginning of each group with follow-up to present were compared. Results were generally the same with no great change in 15 and 20 years as compared to those at 5 years. The complication of perilymph fistula was caused by creating an opening in the footplate much larger than the prosthesis and was eliminated by interposing a living oval window seal if the opening was much larger than the prosthesis and a flap of lining membrane from the promontory when it was not. Other factors that influence a good result are discussed, including the type and the diameter of the piston used, the type of living oval window seal and the method of attachment to the incus. The small fenestra operation was found to be superior to the large, not only for the hearing gain achieved, but the case of performance and the freedom from complications due to migration of the prosthesis and/or the oval window seal. At present we have done about all that can be done for the conductive components. What remains is the sensorineural component which our studies indicate may be due to an autoimmune response.

    This report provides a further analysis of the year 4 weight losses in the Look AHEAD (Action for Health in Diabetes) study and identifies factors associated with long-term success. A total of 5145 overweight/obese men and women with type 2 diabetes were randomly assigned to an intensive lifestyle intervention (ILI) or a usual care group, referred to as Diabetes Support and Education (DSE). ILI participants were provided approximately weekly group or individual treatment in year 1; continued but less frequent contact was provided in years 2–4. DSE participants received three group educational sessions in all years. As reported previously, at year 4, ILI participants lost an average of 4.7% of initial weight, compared with 1.1% for DSE (p<0.0001). More ILI than DSE participants lost ≥5% (46% vs 25%, p<0.0001) and ≥10% (23% vs 10%, p<0.0001) of initial weight. Within the ILI, acheivement of both the 5% and 10% categorical weight losses at year 4 was strongly related to meeting these goals at year 1. A total of 887 participants in ILI lost ≥10% at year 1, of whom 374 (42.2%) achieved this loss at year 4. Participants who maintained the loss, compared with those who did not, attended more treatment sessions and reported more favorable physical activity and food intake at year 4. These results provide critical evidence that a comprehensive lifestyle intervention can induce clinically significant weight loss (i.e., ≥5%) in overweight/obese participants with type 2 diabetes and maintain this loss in more than 45% of patients at 4 years.

    An improved understanding of the transmission dynamics of multidrug-resistant (MDR) gram-negative bacteria and the mechanism of acquisition in long-term care facilities (LTCFs) could aid in the development of prevention strategies specific to LTCFs. We thus investigated the incidence of acquisition of these pathogens among an LTCF population. Prospective cohort study. Three separate wards at a 600-bed LTCF in metropolitan Boston, Massachusetts, during the period October 31, 2006, through October 22, 2007. One hundred seventy-two LTCF residents. A series of rectal samples were cultured to determine acquisition of MDR gram-negative bacteria, defined as absence of MDR gram-negative bacterial colonization at baseline and de novo recovery of MDR gram-negative bacteria from a follow-up culture. Molecular typing was performed to identify genetically linked strains. A nested matched case-control study was performed to identify risk factors associated with acquisition. Among 135 residents for whom at least 1 follow-up culture was performed, 52 (39%) acquired at least 1 MDR gram-negative organism during the study period. Thirty-two residents (62%) had not been colonized at baseline and had acquired at least 1 MDR gram-negative species at follow-up culture, and 20 residents (38%) were colonized at baseline and had acquired at least 1 MDR gram-negative species at follow-up culture. The most common coresistance pattern was resistance to extended-spectrum penicillins, ciprofloxacin, and gentamicin (57 isolates [42.5%]). Genetically related strains of MDR gram-negative bacteria were identified among multiple residents and between roommates. On conditional logistic regression analysis, antibiotic exposure during the study period was significantly associated with acquisition of MDR gram-negative bacteria (odds ratio, 5.6 [95% confidence interval, 1.1-28.7]; P = .04). Acquisition of MDR gram-negative bacteria occurred frequently through resident-to-resident transmission. Existing

    An inadequate supply of oxygen in the brain may lead to the introduction of an inflammatory response through neuronal and glial cells that can result in neuronal damage. Tumor necrosis factor alpha (TNF-α) is a pro-inflammatory cytokine that is released during acute hypoxia and can have neurotoxic or neuroprotective effects in the brain. Both TNF-α and interleukin-1β (IL-1β) have been shown by a number of research groups to alter synaptic scaling and also to inhibit long-term potentiation (LTP) in the hippocampus when induced by specific high frequency stimulation protocols. In this study we have examined the effects of TNF-α on synaptic transmission and plasticity in hippocampal slices after acute hypoxia using two high frequency stimulation protocols. Field excitatory postsynaptic potentials were elicited in the medial perforant pathway of the dentate gyrus. Exogenous TNF-α (5 ng/ml) attenuated LTP induced by theta burst stimulation but had no effect on LTP induced by a more prolonged high frequency stimulation (HFS). Pre-treatment with lipopolysaccharide (100 ng/ml) or TNF-α but not IL-1β (4 ng/ml) prior to a 30 min hypoxic insult resulted in a significant enhancement of LTP post hypoxia when induced by the HFS. Anti-TNF, 3,6 dithiothalidomide (a TNF-α synthesis inhibitor) and SB203580 (a p38 MAPK inhibitor) significantly reduced this effect. These results indicate an important modulatory role for elevated TNF-α levels on LTP in the hippocampus after an acute hypoxic event. PMID:25641742

    Hydrological connectivity has emerged in recent years as a critical factor for understanding the transference of runoff, sediments and nutrients across scales. Here we examine its relevance for the successful reclamation of water-limited environments in which vegetation stability largely depends on optimal redistribution of water and soil resources for plant production. We studied the connectivity of runoff and sediments across plot to slope scales in three Mediterranean-dry reclaimed slopes that were restored about 25 years ago and have developed different levels of vegetation cover (24-51%) and rill density (0.5-0.0 m m-2), along a gradient of overland flow (slope-scale runoff coefficient 11.2%-0.5%). Event-based connectivity of runoff and sediments was controlled by the spatial organization of vegetation and rills, and at the same time was modulated by storm intensity. In absence of rill networks, both runoff and sediment yield per unit area decreased from patch to slope scales due to internal redistribution of both water and sediment fluxes. However, the connectivity of the slopes increased with rainfall intensity. Additionally, the presence of rills largely increased the connectivity of runoff and sediments, leading to increases in sediment yield across scales due to active rilling under high intensity storm conditions. Further simulations using an eco-geomorphic modelling approach showed that the development of rill networks structurally enhances the hydrological connectivity in these systems, providing persistent pathways for the routing of water and soil resources out of the slopes that can compromise the development and long-term stability of reclaimed vegetation. Overall, our results confirm the relevance and efficiency of using a surface connectivity analysis for understanding the spatial and temporal dynamics of water-limited eco-geomorphic systems, and call for its application in order to achieve a successful restoration of Mediterranean slopes.

    Aquatic species living in running waters are widely acknowledged to be vulnerable to climate-induced, thermal and hydrological fluctuations. Climate changes can interact with other environmental changes to determine structural and functional attributes of communities. Although such complex interactions are most likely to occur in a multiple-stressor context as frequently encountered in large rivers, they have received little attention in such ecosystems. In this study, we aimed at specifically addressing the issue of relative long-term effects of global and local changes on benthic macroinvertebrate communities in multistressed large rivers. We assessed effects of hydroclimatic vs. water quality factors on invertebrate community structure and composition over 30 years (1979-2008) in the Middle Loire River, France. As observed in other large European rivers, water warming over the three decades (+0.9 °C between 1979-1988 and 1999-2008) and to a lesser extent discharge reduction (-80 m(3) s(-1) ) were significantly involved in the disappearance or decrease in taxa typical from fast running, cold waters (e.g. Chloroperlidae and Potamanthidae). They explained also a major part of the appearance and increase of taxa typical from slow flowing or standing waters and warmer temperatures, including invasive species (e.g. Corbicula sp. and Atyaephyra desmarestii). However, this shift towards a generalist and pollution tolerant assemblage was partially confounded by local improvement in water quality (i.e. phosphate input reduction by about two thirds and eutrophication limitation by almost one half), explaining a significant part of the settlement of new pollution-sensitive taxa (e.g. the caddisfly Brachycentridae and Philopotamidae families) during the last years of the study period. The regain in such taxa allowed maintaining a certain level of specialization in the invertebrate community despite climate change effects.

    Objectives The purpose of this study was to use decision tree analysis to explore the factors associated with pressure ulcers (PUs) among elderly people admitted to Korean long-term care facilities. Methods The data were extracted from the 2014 National Inpatient Sample (NIS)—data of Health Insurance Review and Assessment Service (HIRA). A MapReduce-based program was implemented to join and filter 5 tables of the NIS. The outcome predicted by the decision tree model was the prevalence of PUs as defined by the Korean Standard Classification of Disease-7 (KCD-7; code L89*). Using R 3.3.1, a decision tree was generated with the finalized 15,856 cases and 830 variables. Results The decision tree displayed 15 subgroups with 8 variables showing 0.804 accuracy, 0.820 sensitivity, and 0.787 specificity. The most significant primary predictor of PUs was length of stay less than 0.5 day. Other predictors were the presence of an infectious wound dressing, followed by having diagnoses numbering less than 3.5 and the presence of a simple dressing. Among diagnoses, “injuries to the hip and thigh” was the top predictor ranking 5th overall. Total hospital cost exceeding 2,200,000 Korean won (US $2,000) rounded out the top 7. Conclusions These results support previous studies that showed length of stay, comorbidity, and total hospital cost were associated with PUs. Moreover, wound dressings were commonly used to treat PUs. They also show that machine learning, such as a decision tree, could effectively predict PUs using big data. PMID:28261530

    To reach insurance physician (IPs) consensus on factors that must be taken into account in the assessment of the work ability of employees who are sick-listed for 2 years. A Delphi study using online questionnaires was conducted from October 2010 to March 2011. One hundred and two insurance physicians reached a consensus on important factors for return to work (RTW) of employees on long-term sick leave; from those factors, the most relevant for the assessment of work ability was determined. From a total of 22 relevant factors considered for the return to work of long-term sick-listed employees, consensus was reached on nine relevant factors that need to be taken into account in the assessment of the work ability of employees on long-term sick leave. Relevant factors that support return to work are motivation, attitude towards RTW, assessment of cognitions and behaviour, vocational rehabilitation in an early stage and instruction for the sick-listed employee to cope with his disabilities. Relevant factors that hinder RTW are secondary gain from illness, negative perceptions of illness, inefficient coping style and incorrect advice of treating physicians regarding RTW. Non-medical personal and environmental factors may either hinder or promote RTW and must be considered in the assessment of the work ability of long-term sick-listed employees. Assessment of work ability should start early during the sick leave period. These factors may be used by IPs to improve the quality of the assessment of the work ability of employees on long-term sick leave.

    Nineteen patients (11 women and eight men) aged 20-68 received long-term parenteral nutrition, mostly at home, for six to 63 months (mean 19 months). Indications for LTPN were extensive, active Crohn's disease in three patients, intestinocutaneous fistulas in three, and short-bowel syndrome in the remaining 13 patients. Subclavian or intra-atrial (Broviac) catheters were most commonly used, for which the average life was four and seven months respectively. Complications of long-term parenteral nutrition included pneumothorax in four out of 48 subclavian vein punctures. Catheter-induced thrombosis of central veins was shown by phlebography 17 times in nine patients, and eight episodes of total occlusion occurred. Two of these patients had pulmonary infarction. Nineteen episodes of catheter sepsis occurred in 11 patients, but only one was fatal. Complications related to intestinal disease included intra-abdominal abscesses and intestinal fistulas, and disturbances of liver function. Five patients died, though in only two was death related to long-term parenteral nutrition. One of these patients died from catheter sepsis, the other had subdural haematoma possibly caused by anticoagulant treatment. Eight of the 14 surviving patients still needed parenteral nutrition. All received a disability pension, but six had an acceptable quality of life with almost normal social activities. Despite problems such as difficulties in maintaining standardised infusion programmes, it was concluded that long-term parenteral nutrition at home is practicable and consistent with an acceptable quality of life.

    Portal vein stenosis develops due to different causes including postoperative inflammation and oncological processes. However, limited effective therapy is available for portal vein stenosis. The objectives of this study were to evaluate the efficacy of a portal vein stent for portal vein stenosis after hepatobiliary pancreatic surgery and to determine the factors associated with stent patency. From December 2003 to December 2015, portal vein stents were implanted in 29 patients who had portal vein stenosis after hepatobiliary pancreatic surgery. We conducted a retrospective analysis to evaluate the efficacy and safety of portal vein stent placement. Twelve clinical variables were analyzed for their role in stent patency. The symptoms before portal vein stent placements included nine patients with hepatic encephalopathy, six patients with gastrointestinal bleeding, four patients with ascites, and four patients with hyperbilirubinemia. Portal vein thrombosis due to postoperative portal stenosis was found in four patients. Portal vein stent were successfully implanted without any major complications. Of the 21 patients with symptoms, 17 showed improvement, and stent patency was maintained in 22 (76%) patients. The presence of a collateral vein is the only variable related to the development of an occlusion after portal stenting. Portal vein stent were implanted safely and had good long-term patency. This procedure is useful to relieve portal hypertension-related symptoms and to improve the quality of life. Our data strongly suggest that embolization to block blood flow in a collateral vein during portal vein stent placement will improve the patency of the stent.

    Differences in biological changes from weight loss by energy restriction and/or exercise may be associated with differences in long-term weight loss/regain. To assess the effect of weight loss method on long-term changes in weight, body composition and chronic disease risk factors. PubMed and Embase were searched (January 1990-October 2013) for studies with data on the effect of energy restriction, exercise (aerobic and resistance) on long-term weight loss. Twenty articles were included in this review. Primary source, peer reviewed randomized trials published in English with an active weight loss period of >6 months, or active weight loss with a follow-up period of any duration, conducted in overweight or obese adults were included. Considerable heterogeneity across trials existed for important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and grouped by comparisons (e.g. diet vs. aerobic exercise, diet vs. diet + aerobic exercise etc.) and study design (long-term or weight loss/follow-up). Forty percent of trials reported significantly greater long-term weight loss with diet compared with aerobic exercise, while results for differences in weight regain were inconclusive. Diet+aerobic exercise resulted in significantly greater weight loss than diet alone in 50% of trials. However, weight regain (∼ 55% of loss) was similar in diet and diet+aerobic exercise groups. Fat-free mass tended to be preserved when interventions included exercise.

    Purpose: To analyze our long-term experience and prognostic factors after fractionated stereotactic radiotherapy (FSRT) in patients with benign or atypical intracranial meningioma. Methods and materials: Between January 1985 and December 2001, 317 patients with a median age of 55.7 years were treated with FSRT for intracranial meningioma. The tumor distribution was World Health Organization (WHO) Grade 1 in 48.3%, WHO Grade 2 in 8.2%, and unknown in 43.5%. Of the 317 patients, 97 underwent RT as their primary treatment, 79 underwent postoperative RT (subtotal resection in 38 and biopsy only in 41), and 141 were treated for recurrent disease. The median target volume was 33.6 cm{sup 3} (range, 1.0-412.6 cm{sup 3}). The median total dose was 57.6 Gy at 1.8 Gy/fraction five times weekly. Results: The median follow-up was 5.7 years (range, 1.2-14.3 years). The overall local tumor control rate was 93.1% (295 of 317). Of the 317 patients, 72 had a partial response on CT/MRI and 223 (70.4%) remained stable. At a median of 4.5 years after FSRT, 22 patients (6.9%) had local tumor progression on MRI. Local tumor failure was significantly greater in patients with WHO Grade 2 meningioma (p < 0.002) than in patients with WHO Grade 1 or unknown histologic features. Patients treated for recurrent meningioma showed a trend toward decreased progression-free survival compared with patients treated with primary therapy, after biopsy, or after subtotal resection (p < 0.06). Patients with a tumor volume >60 cm{sup 3} had a recurrence rate of 15.5% vs. 4.3% for those with a tumor volume of {<=}60 cm{sup 3} (p < 0.001). In 42.9% of the patients, preexisting neurologic deficits improved. Worsening of preexisting neurologic symptoms occurred in 8.2%. Eight patients developed new clinical symptoms, such as reduced vision, trigeminal neuralgia, and intermittent tinnitus located at the side of the irradiated meningioma after FSRT. Conclusion: These data have demonstrated that FSRT is an

    Peritonitis before peritoneal dialysis (PD) training (pretraining peritonitis [PTP]) is an uncommon event. The study aim was to examine the causative organisms, clinical outcomes, risk factors, and long-term consequences of PTP. In this single-center, retrospective, observational study involving all incident patients on PD who developed PTP between 1998 and 2012, we examined the causative organisms, primary response rate, complete cure rate, risk factors, and associations of PTP with peritoneal equilibration test (PET) and patient survival. For each patient in the PTP group, the patients who underwent catheter insertion immediately before and after the index case were identified as controls. Among 1252 incident patients on PD, 52 (4.2%) patients developed PTP, and 104 patients were identified as controls. The two groups were similar in age, sex distribution, comorbidities, and residual renal function, but the PTP group had significantly lower hemoglobin and serum albumin. Patients were followed up for a median of 37.5 months (interquartile range [IQR], 16.3-62.2 months). The most common causative organisms of PTP were Staphylococcus aureus (30.8%) and polymicrobial (21.2%); 25% had negative growth. The primary response and complete cure rates were 82.7% and 78.8%, respectively. In the PTP group, 7.7% of patients died, 9.6% of patients required catheter removal, and PD training was significantly delayed (median =42.0; IQR, 26.0-65.8 days versus 27.5; IQR, 23.0-35.0 days; P=0.01). Multivariate logistic regression analysis showed that serum albumin was the only predictor of PTP (adjusted odds ratio, 0.89 per 1-g/dl increase; 95% confidence interval, 0.82 to 0.97). There were no differences in PET results and dialysis adequacy (measured around 1 month after PD training). The PTP group had significantly worse patient survival (median =41.2; IQR, 21.8-60.5 months versus 55.8; IQR, 40.4-71.2 months; P=0.02).

    With the rapid increase in the number of long-term care hospitals in Korea, care quality has become an important issue. Urinary incontinence is an important condition affecting many residents' quality of life. Thus, it is important that urinary incontinence be amenable to improving conditions with appropriate interventions, since a change in urinary incontinence status can reflect care quality in long-term care facilities if patient level factors are adjusted. We aim to examine the impact of organizational factors on urinary incontinence care quality defined as the improvement of urinary incontinence status or maintenance of continent status post-admission to Korean long-term care hospitals. DESIGN AND DATA: This is a longitudinal correlation study. Data came from two sources: monthly patient assessment reports using the Patient Assessment Instrument and the hospital information system from the Health Insurance Review and Assessment Services. The final analysis includes 5271 elderly adults without indwelling urinary catheter or urostomy who were admitted to 534 Korean long-term care hospitals in April 2008. Multi-level logistic analysis was used to explore the organizational factors that influence urinary incontinence care quality controlling for patient level factors. With respect to the organizational factors, the findings showed that location and RN/total nursing staff ratio variables were statistically significant, controlling for risk factors at the patient level. The odds of urinary incontinence improvement from admission in urban long-term care hospitals were 1.28 times higher than rural long-term care hospitals. In addition, when a long-term care hospital increased one standard deviation (0.19) in the RN ratio, the odds of urinary incontinence status improvement or maintenance of continence status from admission increased about 1.8 times. The most significant finding was that a higher RN to patient ratio and urban location were associated with better

    The aim of this research was to determine the factors that facilitate or hinder high quality nursing care for older people in long-term care settings in Ireland. The quality of care for older people living in long-term care has been identified as an issue of concern in many nursing research studies. While many factors which have an impact on care have been identified, it is difficult to determine key factors from current research. This was a mixed method study, which involved qualitative and quantitative approaches. A self-response questionnaire was generated from data gathered by interview and analysis of literature. Information was collected from 498 nurses working in long-term care settings within a Health Board. A 68% response rate was achieved. Factor analysis was used to identify facilitating and hindering factors of quality care for older people. Nine factors where identified six facilitating factors of quality and three hindering factors of quality care. The six factors, which facilitate quality, were: an ethos of promoting independence and autonomy; a homelike social environment; person centred, holistic care; knowledgeable, skilled staff; knowing the person and adequate multidisciplinary resources. The three factors which hindered quality care; these were: a lack of time and patient choice, resistance to change and bound by routine. The findings of this research provide nurses with a clear set of facilitating and hindering factors of quality care for older people and reveal some of the complexities and challenges of providing this care. Long-term care is the home of many older people and attention within these environments to the facilitating and hindering factors of quality is required. It is hoped that the factors generated in this study add to understanding in relation to quality care and the factors that influence this.

    To examine changes and explanatory variables for changes in health-related quality of life in patients treated with long-term mechanical ventilation over a six-year period. Long-term mechanical ventilation is a treatment for individuals with chronic hypercapnic respiratory failure, primarily caused by neuromuscular diseases, obesity hypoventilation syndrome, chronic obstructive pulmonary and restrictive thoracic diseases. Studies on long-term outcome on health-related quality of life and factors influencing it are lacking. Prospective cohort study. Data were collected from the Norwegian Long-Term-Mechanical-Ventilation Registry and from patient reported questionnaire in 2008 and 2014. Health-related quality of life was measured by the Severe Respiratory Insufficiency questionnaire, containing 49 items and seven subdomains. Linear mixed effects models were used to measure changes and identify factors for changes. After six years, 60 patients were still participating, out of 127 at baseline. Health-related quality of life improved significantly in the total score and in four subdomains of the questionnaire. Satisfaction with training in long-term mechanical ventilation was an explanatory variable for improved 'psychological well-being' and follow-up for improvement of 'anxiety'. Side effects of the treatment like facial soreness were associated with the total score. High age and high forced vital capacity were related to lower 'physical function' and improved 'social functioning', respectively. Long-term mechanical ventilation over six years improved health-related quality of life in most patients. Patient training, follow-up and reduction of side effects, largely delivered by trained nurses, contribute to achieve the main goal of the treatment - improved health-related quality of life.

    The literature is sparse on reproducibility of self-reported exposure to physical ergonomics risk factors for musculoskeletal disorders (MSDs). Aims of this study were to evaluate, in a cohort of workers interviewed up to three times: 1-year test-retest reliability; and 5- and 6-year recall of physical exposures. We also examined whether reproducibility was influenced by the presence of UE MSD or by technological changes introduced between the last two surveys. A cohort of automobile manufacturing employees was interviewed at baseline, one and six years later about work history, physical and psychosocial exposures at work, upper limb symptoms, injury and medical history, and demographics. Agreement between interviews was evaluated by intraclass correlation and Spearman coefficients. Differences in exposure between 1- and 6-year follow-up were analyzed by Wilcoxon matched-pairs signed-ranks test. Large and significant decreases in work pace and physical effort were observed from baseline, although an upper extremity composite index was quite stable in the total population. One-year test-retest reliability was fair to good for the composite exposure index (ICC=0.58), whole-body vibration, handling parts, and tool use, but poor for the other variables considered. Long-term reproducibility, from baseline or 1-year follow-up to 6-year follow-up, was poor for the composite index and almost all single items. UE MSD case status influenced 1-year test-retest reliability, with subjects who changed case status from baseline displaying higher reliability, but not reproducibility of recalled exposures. A strong regression to the mean effect was observed on exposures reported at follow-up surveys. Recalled ergonomics exposures could be employed in retrospective cohort studies as a somewhat reliable and unbiased estimate of the self-reported exposures that would have been obtained up to one year earlier, but not over a longer period (5-6 years). These longer-term results may have

    Background The best treatment for end-stage renal disease (ESRD) is kidney transplantation. Twenty-seven percent of transplantations in Norway are from living donors. Recent studies have shown an increased risk of ESRD and increased mortality in donors. The aim of this study was to determine if the levels of the new biomarkers neutrophil gelatinase-associated lipocalin (NGAL), soluble Klotho (sKlotho), and fibroblast growth factor 23 (FGF23) are changed in kidney donors with normal kidney function defined as an estimated glomerular filtration rate (eGFR) >60 ml/min/1.73 m2 compared to patients with chronic kidney disease (CKD) stages 3-5 and healthy controls. Methods This is a cross-sectional, observational, single-center study including 35 kidney donors with an eGFR ≥60 ml/min/1.73 m2 5 years after donation, 22 patients with CKD stage 3 (eGFR 30-59 ml/min/1.73 m2), 18 patients with CKD stage 4 (eGFR 15-29 ml/min/1.73 m2), 20 patients with CKD stage 5 (eGFR <15 ml/min/1.73 m2), and 35 controls comparing levels of biomarkers in long-term kidney donors with those in CKD patients and healthy controls. Results The level of log NGAL was significantly higher in donors than in healthy controls (2.02 ± 0.10 vs. 1.89 ± 0.10 ng/ml; p < 0.001), and the level increased with declining kidney function. The log FGF23 level was nonsignificantly higher in donors than in controls, but it significantly increased with declining kidney function. The log sKlotho levels were significantly lower in patients with CKD stages 4 and 5 than in controls, but no difference was revealed between controls and donors. Conclusion Kidney donors have significantly higher levels of NGAL than healthy controls after a median of 15 years (range 5-38). NGAL could be a valuable diagnostic marker in the future. FGF23 and sKlotho were not significantly different between donors and controls. PMID:27920796

    Groin pain is the third most common disease in football players and has often been associated with hip pathology such as femoroacetabular impingement and labral lesions. Hip arthroscopy offers possibilities of function restoration via minimally invasive procedures. The aim of this study is to evaluate professional football player's injuries and their return to play after hip arthroscopy for FAI and labral injuries. Patients that underwent hip arthroscopy between 2009 and 2014 were selected retrospectively. From this population, only professional soccer players competing at national level were included (Tegner 10). Arthroscopic surgery was proposed in patients with persistent pain. All patients were assessed for VAS score preoperatively and at 3, 6, 12 and 24 months post-op. HOS (sport and DLA) and mHHS tests were performed at the same time periods. All patients were men with a mean age of 26.5 ± 7.1 years old. Preoperative VAS (7.4 ± 1.3), HOS ADL (67.7 ± 5.5), HOS sport (37.6 ± 18.7) and mHHS (72.5 ± 8.8) showed improved scores during long-term follow-up. Time to return to play was 10.8 months (SD ± 4.3), with range between 4 and 20 months. Mean follow-up was 45.4 ± 15.6 months (range from 26 to 72 months). No differences were observed between non-active and active patients at final follow-up with respect to chondral lesions, but significant differences were observed with reference to management of the labrum (p = 0.031), where a higher rate of labrectomies existed among inactive patients and a higher rate of suture among active patients. Hip arthroscopy is a safe procedure with very good return to play results, but for optimized return to football one should consider patient age at the time of surgery, the condition of the labrum and low scores on the Harris Hip Score (mHHS) and HOS (sport version) as predictive factors for poor prognosis. Level of evidence IV.

    Second malignant neoplasms, cardiovascular disease, neurotoxicity and ototoxicity, pulmonary complications, hypogonadism, and nephrotoxicity are potentially life-threatening long-term complications of testicular cancer and its therapy. This article describes the pathogenesis, risks, and management of these late effects experienced by long-term testicular cancer survivors, who are defined as individuals who are disease free 5 years or more after primary treatment. Testicular cancer survivors should follow applicable national guidelines for cancer screening and management of cardiovascular disease risk factors. In addition, health care providers should capitalize on the time of cancer diagnosis as a teachable moment to introduce and promote lifestyle changes.

    There is little information concerning the long term outcome of patients with gastro-oesophageal reflux disease (GORD). Thus 109 patients with reflux symptoms (33 with erosive oesophagitis) with a diagnosis of GORD after clinical evaluation and oesophageal testing were studied. All patients were treated with a stepwise approach: (a) lifestyle changes were suggested aimed at reducing reflux and antacids and the prokinetic agent domperidone were prescribed; (b) H2 blockers were added after two months when symptoms persisted; (c) anti-reflux surgery was indicated when there was no response to (b). Treatment was adjusted to maintain clinical remission during follow up. Long term treatment need was defined as minor when conservative measures sufficed for proper control, and as major if daily H2 blockers or surgery were required. The results showed that one third of the patients each had initial therapeutic need (a), (b), and (c). Of 103 patients available for follow up at three years and 89 at six years, respective therapeutic needs were minor in 52% and 55% and major in 48% and 45%. Eighty per cent of patients in (a), 67% in (b), and 17% in (c) required only conservative measures at six years. A decreasing lower oesophageal sphincter pressure (p < 0.001), radiological reflux (p = 0.028), and erosive oesophagitis (p = 0.031), but not initial clinical scores, were independent predictors of major therapeutic need as shown by multivariate analysis. The long term outcome of GORD is better than previously perceived. PMID:8307456

    To examine the efficacy of counselor-assisted problem solving (CAPS) in improving long-term caregiver psychological functioning following traumatic brain injury (TBI) in adolescents. This randomized clinical trial compared CAPS (n = 65), a predominantly online problem-solving intervention, with an Internet resource comparison (n = 67) program. Families of adolescents with TBI completed a baseline assessment and follow-up assessments 6, 12, and 18 months later. General linear mixed models were used to examine longitudinal changes in caregiver global psychological distress, depressive symptoms, and caregiving self-efficacy. Family income and injury severity were examined as moderators of treatment efficacy. Family income moderated long-term changes in caregiver psychological distress. For lower-income caregivers, the CAPS intervention was associated with lower levels of psychological distress at 6, 12, and 18 months post baseline. These findings support the utility of Web-based interventions in improving long-term caregiver psychological distress, particularly for lower-income families. © The Author 2015.

    To review the audiologic results in a cohort of patients surgically treated for cholesteatoma. Retrospective review of patient records. Tertiary referral center. A retrospective study of patients operated on for acquired middle ear cholesteatoma during the period 1990 to 2002 was performed. A total of 758 patients were followed during a short-term period, and 611 patients were followed during a long-term period. The patients were divided into 3 age groups: children, adolescents, and adults. The localization of cholesteatoma was classified as attic, sinus, or tensa. Closed tympanoplasty was always performed as the single procedure of choice on all the children, and reoperation or conversion to open tympanoplasty was made later if needed. Adult patients were treated with single classic canal wall up, or wall down (CWD), according to the propagation of disease and condition of middle ear. Preoperative and postoperative air-bone gap (ABG) and pure-tone average were compared after short-term and long-term follow-up. Average hearing improvement (reduction of ABG) amounted 20.0 dB for short-term and deteriorated to 18.0 dB during long-term analysis for all the patients. Preoperative hearing level was significantly worse for CWD than for intact canal wall technique. The ABG closure was much better in the group with attic cholesteatoma. Both preoperative and postoperative hearing levels were worse for children than for adolescents or adults. Revision operations and bilateral cholesteatoma gave worse total postoperative hearing. The long-term results of primary operations, when recurrent cholesteatoma did not occur, were stable. Damage to auditory ossicles correlated well with total preoperative and postoperative results. The most hearing improvement was verified for the frequencies between 500 and 3,000 Hz, and there was no sensorineural hearing loss. The audiologic results of cholesteatoma surgery are preserved during long-term follow-up. We found that recurrent

    To date, the biological activity of granulocyte macrophage-colony stimulating factor (GM-CSF) has been investigated by using mostly Escherichia coli- or yeast cell-derived recombinant human GM-CSF (erhGM-CSF and yrhGM-CSF, respectively). However, Chinese hamster ovary cell-derived recombinant human GM-CSF (crhGM-CSF), as well as natural human GM-CSF, is a distinct molecule that includes modifications by complicated oligosaccharide moieties. In the present study, we reevaluated the bioactivity of crhGM-CSF by comparing it with those of erhGM-CSF and yrhGM-CSF. The effect of short-term stimulation (0.5h) on the activation of neutrophils/monocytes or peripheral blood mononuclear cells (PBMCs) by crhGM-CSF was lower than those with erhGM-CSF or yrhGM-CSF at low concentrations (under 60pM). Intermediate-term stimulation (24h) among the different rhGM-CSFs with respect to its effect on the activation of TF-1 cells, a GM-CSF-dependent cell line, or PBMCs was not significantly different. In contrast, the proliferation/survival of TF-1 cells or PBMCs after long-term stimulation (72-168h) was higher at low concentrations of crhGM-CSF (15-30pM) than that of cells treated with other GM-CSFs. The proportion of apoptotic TF-1 cells after incubation with crhGM-CSF for 72h was lower than that of cells incubated with other rhGM-CSFs. These effects were attenuated by desialylation of crhGM-CSF. Clearance of crhGM-CSF but not desialylated-crhGM-CSF by both TF-1 cells and PBMCs was delayed compared with that of erhGM-CSF or yrhGM-CSF. These results suggest that sialylation of oligosaccharide moieties delayed the clearance of GM-CSF, thus eliciting increased long-term bioactivity in vitro. Copyright © 2014 Elsevier Ltd.

    Despite an increasing literature on professional nurses' job satisfaction, job satisfaction by nonprofessional nursing care providers and, in particular, in residential long-term care facilities, is sparsely described. The purpose of this study was to systematically review the evidence on which factors (individual and organizational) are associated with job satisfaction among care aides, nurse aides, and nursing assistants, who provide the majority of direct resident care, in residential long-term care facilities. Nine online databases were searched. Two authors independently screened, and extracted data and assessed the included publications for methodological quality. Decision rules were developed a priori to draw conclusions on which factors are important to care aide job satisfaction. Forty-two publications were included. Individual factors found to be important were empowerment and autonomy. Six additional individual factors were found to be not important: age, ethnicity, gender, education level, attending specialized training, and years of experience. Organizational factors found to be important were facility resources and workload. Two additional factors were found to be not important: satisfaction with salary/benefits and job performance. Factors important to care aide job satisfaction differ from those reported among hospital nurses, supporting the need for different strategies to improve care aide job satisfaction in residential long-term care.

    Non-invasive measures for assessing long-term stress in free ranging mammals are an increasingly important approach for understanding physiological responses to landscape conditions. Using a spatially and temporally expansive dataset of hair cortisol concentrations (HCC) generated from a threatened grizzly bear (Ursus arctos) population in Alberta, Canada, we quantified how variables representing habitat conditions and anthropogenic disturbance impact long-term stress in grizzly bears. We characterized spatial variability in male and female HCC point data using kernel density estimation and quantified variable influence on spatial patterns of male and female HCC stress surfaces using random forests. Separate models were developed for regions inside and outside of parks and protected areas to account for substantial differences in anthropogenic activity and disturbance within the study area. Variance explained in the random forest models ranged from 55.34% to 74.96% for males and 58.15% to 68.46% for females. Predicted HCC levels were higher for females compared to males. Generally, high spatially continuous female HCC levels were associated with parks and protected areas while low-to-moderate levels were associated with increased anthropogenic disturbance. In contrast, male HCC levels were low in parks and protected areas and low-to-moderate in areas with increased anthropogenic disturbance. Spatial variability in gender-specific HCC levels reveal that the type and intensity of external stressors are not uniform across the landscape and that male and female grizzly bears may be exposed to, or perceive, potential stressors differently. We suggest observed spatial patterns of long-term stress may be the result of the availability and distribution of foods related to disturbance features, potential sexual segregation in available habitat selection, and may not be influenced by sources of mortality which represent acute traumas.

    Preeclampsia is a cardiovascular (CV) disease risk factor, and lifestyle modifications are recommended. It was suggested that preeclampsia may increase the prevalence of various CV disease risk factors such as metabolic syndrome, hypertension, insulin resistance, microalbuminuria, and endothelial dysfunction, among others. Here, we investigate the role of serum uric acid in preeclampsia in the development of CV complications. This was an observational case-control study that compared women with history of preeclampsia (n = 25) with age-matched controls with uncomplicated pregnancies (n = 20) who were followed for at least 5 years. Measurements included clinical and ambulatory blood pressure monitoring, ultrasound-measured flow-mediated dilatation (FMD), microalbuminuria, carotid intima-media thickness (CIMT) and serum uric acid, as well as clinical and demographic features. Cardiovascular disease risk factors were compared in women with and without previous preeclampsia. At the time of index gestation, preeclamptic women had higher serum uric acid values (4.36 ± 0.61 vs 2.27 ± 0.38 mg/dL, P < 0.001). Five years after pregnancy, the patients who had preeclampsia were more likely to have hypertension and had higher serum uric acid levels, higher microalbuminuria and CIMT levels, and lower FMD values than did the patients who did not have preeclampsia. The 2 groups were similar with regard to various ambulatory blood pressure parameters. Univariate associates of FMD were history of preeclampsia and the current hypertension status. Microalbuminuria correlated with gestational uric acid levels (coefficient of correlation of 0.40, P = 0.01 for FMD and coefficient of correlation of 0.37, P = 0.01 for CIMT, respectively). Preeclampsia might be a risk factor for the development of cardiovascular risk factors at least 5 years after index pregnancy. Serum uric acid and microalbuminuria may be mechanistic mediators of heightened risk, along with impaired endothelial function

    To determine the association between skin intrinsic fluorescence (SIF), a noninvasive measure of advanced glycation endproducts and oxidative stress in skin, and retinal microvascular complications of long duration type 1 diabetes, proliferative diabetic retinopathy (PDR) and macular edema. A cross-sectional cohort study of persons with type 1 diabetes in the Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR) who participated in a 32-year follow-up examination in 2012-2014. Subjects underwent a physical examination, answered a health questionnaire, and had fundus photographs taken. SIF was measured on the underside of the left forearm near the elbow with the SCOUT DS(®) skin fluorescence spectrometer. Two representative SIF measures were used for these analyses: SIF01 excited by an LED centered at 375 nm with correction factors Kx = 0.6 and Km = 0.2 and SIF15 excited by an LED centered at 456 nm with correction factors Kx = 0.4 and Km = 0.9. The 414 participants had mean diabetes duration of 42.2 years (standard deviation 6.8 years, range 32.9-67.9 years). PDR was statistically significantly associated (p < 0.05) with both SIF measures in multivariate models including other relevant factors (odds ratio [OR] = 1.17 for SIF01 and 1.20 for SIF15). Skin intrinsic fluorescence measures are independently associated with PDR in the WESDR. Incidence information is needed to evaluate whether there is a causal relationship.

    The problem of the prediction of violence in psychiatric patients has led to a proliferation of research over the last decade. This study focuses on enduring patient related risk factors of violence, and investigates which long-term patients in Weskoppies Hospital (a specialist psychiatric hospital) are the most likely to commit violent acts. Nursing statistics on violent incidents and other security breaches were collected for 262 long-term in-patients over a six month period (April - September 2007). The 41 patients who committed violent acts were compared to the 221 non-violent patients in terms of demographic and clinical variables, using two-way tables and Chi-Square or Fisher's Exact Tests. The prevalence of violence among the long-term patients was 16%. Fighting among patients was the most common form of violence (58%). The most significant risk factors of violence among the long-term patients are: A diagnosis of mental retardation; first hospital admission before the age of 40 years; total hospital stay >12 years; current accommodation in a closed ward; habitual verbal aggression; absence of disorganised behaviour; and being clinically evaluated as unsuitable for community placement. The findings will help to identify those long-term patients most at risk of violence. The subgroup of patients with mental retardation is responsible for a isproportionately large number of violent acts in the hospital. The risk lies not so much in their psychiatric symptoms, but more in their cognitive ability, coping skills and inappropriate admission circumstances. Efforts should be directed - at a provincial level - towards their community placement.

    Introduction. Laparoscopic Sleeve Gastrectomy (SG) is considered as successful if the percentage of Excess Body Mass Index Loss (% EBMIL) remains constant over 50% with long-term follow-up. The aim of this study was to evaluate whether early % EBMIL was predictive of success after SG. Methods. This retrospective study included patients who had SG with two years of follow-up. Patients had follow-up appointments at 3 (M3), 6, 12, and 24 months (M24). Data as weight and Body Mass Index (BMI) were collected systematically. We estimated the % EBMIL necessary to establish a correlation between M3 and M24 compared to % EBMIL speeds and calculated a limit value of % EBMIL predictive of success. Results. Data at operative time, M3, and M24 were available for 128 patients. Pearson test showed a correlation between % EBMIL at M3 and that at M24 (r = 0.74; p < 0.0001). % EBMIL speed between surgery and M3 (p = 0.0011) was significant but not between M3 and M24. A linear regression analysis proved that % EBMIL over 20.1% at M3 (p < 0.0001) predicted a final % EBMIL over 50%. Conclusions. % EBMIL at M3 after SG is correlated with % EBMIL in the long term. % EBMIL speed was significant in the first 3 months. % EBMIL over 20.1% at M3 leads to the success of SG.

    Multiple complications are associated with use of ventricular assist devices (VADs). Cardiac-related complications and infections are most frequently reported. VADs, however, can also lead to a number of general surgical complications equally significant in terms of morbidity and mortality. The authors performed a systematic literature search to review current data that specifically relate general surgical complications to patients who undergo left VAD implantation. The review provides a relatively clear understanding of the spectrum of general surgical complications and shows that they contribute significantly to morbidity and mortality in these patients.

    Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is an effective but potentially morbid treatment for colorectal cancer peritoneal metastases. The impact of treatment-related morbidity on long-term survival has been reported in various malignancies, but it has never been assessed in this clinical setting. The aim of this study was to assess the impact of major postoperative complications on oncological outcomes after cytoreduction and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases. Two prospective databases were reviewed. Major complications were defined as grade 3 to 5 according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. The extent of peritoneal involvement was scored by the use of the Peritoneal Cancer Index. This study was conducted in 2 high-volume peritoneal malignancy management centers. One hundred one consecutive patients with peritoneal metastases potentially amenable to macroscopically complete cytoreduction were selected. Peritonectomy procedures and multivisceral resections were used to remove all macroscopic tumor, and mitomycin-C plus cisplatin-based hyperthermic intraperitoneal chemotherapy was used to control microscopic residual disease. The primary outcomes measured were overall and disease-specific survival. Mortality and major morbidity were 3.0%, and 23.8%. Median follow-up was 44.9 months (95% CI, 24.1-65.7). Five-year disease-specific survival was 14.3% for patients who experienced major complications and 52.3% for those who did not (p = 0.001). Five-year overall survival was 11.7% for patients who experienced major complications, and 58.8% for those who did not (p = 0.003). At multivariate analysis, major morbidity correlated to both worse overall and disease-specific survival, along with a Peritoneal Cancer Index >19, and suboptimal cytoreduction. Poor performance status correlated only to worse disease-specific survival, and liver

    Understanding the factors associated with the long-term stress levels of captive animals is important from the view of animal welfare. In this study, we investigated the effects of relocation in addition to individual and environmental factors related to social management on long-term stress level in group-living captive chimpanzees by examining behaviors and hair cortisol (HC). Specifically, we conducted two studies. The first compared changes in HC levels before and after the relocation of 8 chimpanzees (Study 1) and the second examined the relationship between individual and environmental factors and individual HC levels in 58 chimpanzees living in Kumamoto Sanctuary (KS), Kyoto University (Study 2). We hypothesized that relocation, social situation, sex, and early rearing conditions, would affect the HC levels of captive chimpanzees. We cut arm hair from chimpanzees and extracted and assayed cortisol with an enzyme immunoassay. Aggressive behaviors were recorded ad libitum by keepers using a daily behavior monitoring sheet developed for this study. The results of Study 1 indicate that HC levels increased during the first year after relocation to the new environment and then decreased during the second year. We observed individual differences in reactions to relocation and hypothesized that social factors may mediate these changes. In Study 2, we found that the standardized rate of receiving aggression, rearing history, sex, and group formation had a significant influence on mean HC levels. Relocation status was not a significant factor, but mean HC level was positively correlated with the rate of receiving aggression. Mean HC levels were higher in males than in females, and the association between aggressive interactions and HC levels differed by sex. These results suggest that, although relocation can affect long-term stress level, individuals' experiences of aggression and sex may be more important contributors to long-term stress than relocation alone.

    Background Differences in biological changes from weight loss by energy restriction and/or exercise may be associated with differences in long-term weight loss/regain. Objective To assess the effect of weight loss method on long-term changes in weight, body composition and chronic disease risk factors. Data Sources PubMed and Embase were searched (January 1990-October 2013) for studies with data on the effect of energy restriction, exercise (aerobic and resistance) on long-term weight loss. Twenty articles were included in this review. Study Eligibility Criteria Primary source, peer reviewed randomized trials published in English with an active weight loss period of >6 months, or active weight loss with a follow-up period of any duration, conducted in overweight or obese adults were included. Study Appraisal and Synthesis Methods Considerable heterogeneity across trials existed for important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and grouped by comparisons (e.g. diet vs. aerobic exercise, diet vs. diet + aerobic exercise etc.) and study design (long-term or weight loss/follow-up). Results Forty percent of trials reported significantly greater long-term weight loss with diet compared with aerobic exercise, while results for differences in weight regain were inconclusive. Diet+aerobic exercise resulted in significantly greater weight loss than diet alone in 50% of trials. However, weight regain (∼55% of loss) was similar in diet and diet+aerobic exercise groups. Fat-free mass tended to be preserved when interventions included exercise. PMID:25333384
