    Vitamin D insufficiency, defined as low serum concentrations of the major circulating form of vitamin D, 25 hydroxyvitamin D (25(OH)D), has been associated with the development of numerous infectious, inflammatory, and neoplastic disorders in humans. In addition, vitamin D insufficiency has been found to be predictive of mortality for many disorders. However, interpretation of human studies is difficult since vitamin D status is influenced by many factors, including diet, season, latitude, and exposure to UV radiation. In contrast, domesticated cats do not produce vitamin D cutaneously, and most cats are fed a commercial diet containing a relatively standard amount of vitamin D. Consequently, domesticated cats are an attractive model system in which to examine the relationship between serum 25(OH)D and health outcomes. The hypothesis of this study was that vitamin D status would predict short term, all-cause mortality in domesticated cats. Serum concentrations of 25(OH)D, together with a wide range of other clinical, hematological, and biochemical parameters, were measured in 99 consecutively hospitalised cats. Cats which died within 30 days of initial assessment had significantly lower serum 25(OH)D concentrations than cats which survived. In a linear regression model including 12 clinical variables, serum 25(OH)D concentration in the lower tertile was significantly predictive of mortality. The odds ratio of mortality within 30 days was 8.27 (95% confidence interval 2.54-31.52) for cats with a serum 25(OH)D concentration in the lower tertile. In conclusion, this study demonstrates that low serum 25(OH)D concentration status is an independent predictor of short term mortality in cats. PMID:25970442

    Background: Intracerebral hemorrhage (ICH) is a life threatening entity, and an early outcome assessment is mandatory for optimizing therapeutic efforts. Methods: We retrospectively analyzed data from 342 patients with spontaneous primary ICH to evaluate possible predictors of 30-day mortality considering clinical, radiological, and therapeutical parameters. We also applied three widely accepted outcome grading scoring systems [(ICH score, FUNC score and intracerebral hemorrhage grading scale (ICH-GS)] on our population to evaluate the correlation of these scores with the 30-day mortality in our study. We also applied three widely accepted outcome grading scoring systems [(ICH score, FUNC score and intracerebral hemorrhage grading scale (ICH-GS)] on our population to evaluate the correlation of these scores with the 30-day mortality in our study. Results: From 342 patients (mean age: 67 years, mean Glasgow Coma Scale [GCS] on admission: 9, mean ICH volume: 62.19 ml, most common hematoma location: basal ganglia [43.9%]), 102 received surgical and 240 conservative treatment. The 30-day mortality was 25.15%. In a multivariate analysis, GCS (Odds ratio [OR] =0.726, 95% confidence interval [CI] =0.661–0.796, P < 0.001), bleeding volume (OR = 1.012 per ml, 95% CI = 1.007 – 1.017, P < 0.001), and infratentorial hematoma location (OR = 5.381, 95% CI = 2.166-13.356, P = 0.009) were significant predictors for the 30-day mortality. After receiver operating characteristics analysis, we defined a “high-risk group” for an unfavorable short-term outcome with GCS <11 and ICH volume >32 ml supratentorially or 21 ml infratentorially. Using Pearson correlation, we found a correlation of 0.986 between ICH score and 30-day mortality (P < 0.001), 0.853 between FUNC score and 30-day mortality (P = 0.001), and 0.924 between ICH-GS and 30-day mortality (P = 0.001). Conclusions: GCS score on admission together with the baseline volume and localization of the hemorrhage are strong

    2015-01-01

    Background: Pulmonary embolism (PE) is the most life-threatening form of venous thrombosis which causes the majority of mortalities in this category. Obstructive sleep apnea (OSA) has been indicated as one of the risk factors for thromboembolism because of hemostatic alterations. The present study was designed to seek for the relationship between OSA and 30-day mortality of patients with PE. Materials and Methods: This prospective cohort study was conducted among 137 consecutive patients referred to hospital with symptoms of PE and preliminary stable hemodynamic. Confirmation of PE was made by multislice computed tomography pulmonary angiography and in the case of contraindication; V/Q lung scan and Doppler sonography were done. A STOP-Bang Questionnaire was used to determine patients with high- and low-risk of OSA. Patients were followed up for 1-month, and their survivals were recorded. Results: This study showed that there was no relationship between OSA and 30-day mortality (P = 0.389). Chronic kidney disease (P = 0.004), hypertension (P = 0.003), main thrombus (P = 0.004), and segmental thrombus (P = 0.022) were associated with 30-day mortality. In the logistic regression analysis, history of chronic kidney disease was diagnosed as a risk factor for 30-day mortality among the PE patients (P = 0.029, odds ratio = 4.93). Conclusion: Results of this study showed 30-day mortality was not affected by OSA directly. In fact, it was affected by complications of OSA such as hypertension and thrombus. Also, positive history of chronic kidney disease increased the risk of 30-day mortality. PMID:26622255

    Background/Aims: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common medical emergency that can be life threatening. This study evaluated predictive factors of 30-day mortality in patients with this condition. Methods: A prospective observational study was conducted at a single hospital between April 2010 and November 2012, and 336 patients with symptoms and signs of gastrointestinal bleeding were consecutively enrolled. Clinical characteristics and endoscopic findings were reviewed to identify potential factors associated with 30-day mortality. Results: Overall, 184 patients were included in the study (men, 79.3%; mean age, 59.81 years), and 16 patients died within 30 days (8.7%). Multivariate analyses revealed that comorbidity of diabetes mellitus (DM) or metastatic malignancy, age ≥ 65 years, and hypotension (systolic pressure < 90 mmHg) during hospitalization were significant predictive factors of 30-day mortality. Conclusions: Comorbidity of DM or metastatic malignancy, age ≥ 65 years, and hemodynamic instability during hospitalization were predictors of 30-day mortality in patients with NVUGIB. These results will help guide the management of patients with this condition. PMID:26767858

    Abstract Estimating patient survival has hitherto been the main focus when treating metastatic bone disease (MBD) in the appendicular skeleton. This has been done in an attempt to allocate the patient to a surgical procedure that outlives them. No questions have been addressed as to whether the extent of the surgery and thus the surgical trauma reduces survival in this patient group. We wanted to evaluate if perioperative parameters such as blood loss, extent of bone resection, and duration of surgery were risk factors for 30-day mortality in patients having surgery due to MBD in the appendicular skeleton. We retrospectively identified 270 consecutive patients who underwent joint replacement surgery or intercalary spacing for skeletal metastases in the appendicular skeleton from January 1, 2003 to December 31, 2013. We collected intraoperative (duration of surgery, extent of bone resection, and blood loss), demographic (age, gender, American Society of Anesthesiologist score [ASA score], and Karnofsky score), and disease-specific (primary cancer) variables. An association with 30-day mortality was addressed using univariate and multivariable analyses and calculation of odds ratio (OR). All patients were included in the analysis. ASA score 3 + 4 (OR 4.16 [95% confidence interval, CI, 1.80–10.85], P = 0.002) and Karnofsky performance status below 70 (OR 7.34 [95% CI 3.16–19.20], P < 0.001) were associated with increased 30-day mortality in univariate analysis. This did not change in multivariable analysis. No parameters describing the extent of the surgical trauma were found to be associated with 30-day mortality. The 30-day mortality in patients undergoing surgery for MBD is highly dependent on the general health status of the patients as measured by the ASA score and the Karnofsky performance status. The extent of surgery, measured as duration of surgery, blood loss, and degree of bone resection were not associated with 30-day mortality. PMID:27082592

    Background & Aims A consensus conference proposed that cirrhosis-associated acute kidney injury (AKI) be defined as an increase in serum creatinine by >50% from the stable baseline value in <6 months or by ≥0.3mg/dL in <48 hrs. We prospectively evaluated the ability of these criteria to predict mortality within 30 days among hospitalized patients with cirrhosis and infection. Methods 337 patients with cirrhosis admitted with or developed an infection in hospital (56% men; 56±10 y old; model for end-stage liver disease score, 20±8) were followed. We compared data on 30-day mortality, hospital length-of-stay, and organ failure between patients with and without AKI. Results 166 (49%) developed AKI during hospitalization, based on the consensus criteria. Patients who developed AKI had higher admission Child-Pugh (11.0±2.1 vs 9.6±2.1; P<.0001), and MELD scores (23±8 vs17±7; P<.0001), and lower mean arterial pressure (81±16mmHg vs 85±15mmHg; P<.01) than those who did not. Also higher amongst patients with AKI were mortality in ≤30 days (34% vs 7%), intensive care unit transfer (46% vs 20%), ventilation requirement (27% vs 6%), and shock (31% vs 8%); AKI patients also had longer hospital stays (17.8±19.8 days vs 13.3±31.8 days) (all P<.001). 56% of AKI episodes were transient, 28% persistent, and 16% resulted in dialysis. Mortality was 80% among those without renal recovery, higher compared to partial (40%) or complete recovery (15%), or AKI-free patients (7%; P<.0001). Conclusions 30-day mortality is 10-fold higher among infected hospitalized cirrhotic patients with irreversible AKI than those without AKI. The consensus definition of AKI accurately predicts 30-day mortality, length of hospital stay, and organ failure. PMID:23999172

    Despite advanced techniques and improved clinical outcomes, patient survival following coronary artery bypass grafting (CABG) is still a major concern. Therefore, predicting future CABG mortality represents an unmet medical need and should be carefully explored. The objective of this study is to assess whether pre-CABG platelet activity corresponds with 30 days mortality post-CABG. Retrospective analyses of platelet biomarkers and death at 30 days in 478 heart surgery patients withdrawn from aspirin or/and clopidogrel. Platelet activity was assessed prior to CABG for aspirin (ASPI-test) with arachidonic acid and clopidogrel (ADP-test) utilizing Multiplate impedance aggregometer. Most patients (n = 198) underwent conventional CABG, off-pump (n = 162), minimally invasive (n = 30), artificial valve implantation (n = 48) or valves in combination with CABG (n = 40). There were 22 deaths at 30 days, including 10 in-hospital fatalities. With the cut-off value set below 407 area under curve (AUC) for the ASPI-test, the 30-day mortality was 5.90% for the lower cohort and 2.66% for patients with significantly higher platelet reactivity (P = 0.038). For the ADP-test with a cut-off at 400AUC, the 30-day mortality was 9.68% for the lower cohort and 3.66% for patients with higher platelet reactivity, representing a borderline significant difference (P = 0.046). Aside from the platelet indices, patients who received red blood cell (RBC) concentrate had a highly significant (P < 0.0001) risk of death at 30 days. Both aspirin and clopidogrel tests were useful in predicting 30 days mortality following heart surgery, suggesting the danger of diminished platelet activity prior to CABG in such high-risk patients. These preliminary evidence supports early discontinuation of antiplatelet therapy for elective CABG and requires adequately powered randomized trials to test the hypothesis and potentially improve survival.

    Background: Little data are available to prioritize quality improvement initiatives in shoulder surgery. Purpose: To stratify the risk for 30-day postoperative morbidity in commonly performed surgical procedures about the shoulder completed in a hospital setting and to determine patient factors associated with major complications. Study Design: Cohort study; Level of evidence, 3. Methods: This retrospective study utilized the National Surgical Quality Improvement Program (NSQIP) database from the years 2005 to 2010. Using Current Procedural Terminology codes, the database was queried for shoulder cases that were divided into 7 groups: arthroscopy without repair; arthroscopy with repair; arthroplasty; clavicle/acromioclavicular joint (AC) open reduction and internal fixation (ORIF)/repair; ORIF of proximal humeral fracture; open tendon release/repair; and open shoulder stabilization. The primary end point was any major complication, with secondary end points of incisional infection, return to the operating room, and venothromboembolism (VTE), all within 30 days of surgery. Results: Overall, 11,086 cases were analyzed. The overall major complication rate was 2.1% (n = 234). Factors associated with major complications on multivariate analysis included: procedure performed (P < .001), emergency case (P < .001), pulmonary comorbidity (P < .001), preoperative blood transfusion (P = .033), transfer from an outside institution (P = .03), American Society of Anesthesiologists (ASA) score (P = .006), wound class (P < .001), dependent functional status (P = .027), and age older than 60 years (P = .01). After risk adjustment, open shoulder stabilization was associated with the greatest risk of major complications relative to arthroscopy without repair (odds ratio [OR], 5.56; P = .001), followed by ORIF of proximal humerus fracture (OR, 4.90; P < .001) and arthroplasty (OR, 4.40; P < .001). These 3 groups generated over 60% of all major complications. Open shoulder

    Purpose Identification of high-risk patients with pulmonary embolism is vital. The aim of the present study was to examine clinical scores, their single items, and anamnestic features in their ability to predict 30-day mortality. Materials and Methods A retrospective, single-center study from 06/2005 to 01/2010 was performed. Inclusion criteria were presence of pulmonary embolism, availability of patient records and 30-day follow-up. The following clinical scores were calculated: Acute Physiology and Chronic Health Evaluation II, original and simplified pulmonary embolism severity index, Glasgow Coma Scale, and euroSCORE II. Results In the study group of 365 patients 39 patients (10.7%) died within 30 days due to pulmonary embolism. From all examined scores and parameters the best predictor of 30-day mortality were the Glasgow Coma scale (≤ 10) and parameters of the circulatory system including presence of mechanical ventilation, arterial pH (< 7.335), and systolic blood pressure (< 99 mm Hg). Conclusions Easy to ascertain circulatory parameters have the same or higher prognostic value than the clinical scores that were applied in this study. From all clinical scores studied the Glasgow Coma Scale was the most time- and cost-efficient one. PMID:26866472

    Background Outcome measures for patients hospitalized with pneumonia may complement process measures in characterizing quality of care. We sought to develop and validate a hierarchical regression model using Medicare claims data that produces hospital-level, risk-standardized 30-day mortality rates useful for public reporting for patients hospitalized with pneumonia. Methodology/Principal Findings Retrospective study of fee-for-service Medicare beneficiaries age 66 years and older with a principal discharge diagnosis of pneumonia. Candidate risk-adjustment variables included patient demographics, administrative diagnosis codes from the index hospitalization, and all inpatient and outpatient encounters from the year before admission. The model derivation cohort included 224,608 pneumonia cases admitted to 4,664 hospitals in 2000, and validation cohorts included cases from each of years 1998–2003. We compared model-derived state-level standardized mortality estimates with medical record-derived state-level standardized mortality estimates using data from the Medicare National Pneumonia Project on 50,858 patients hospitalized from 1998–2001. The final model included 31 variables and had an area under the Receiver Operating Characteristic curve of 0.72. In each administrative claims validation cohort, model fit was similar to the derivation cohort. The distribution of standardized mortality rates among hospitals ranged from 13.0% to 23.7%, with 25th, 50th, and 75th percentiles of 16.5%, 17.4%, and 18.3%, respectively. Comparing model-derived risk-standardized state mortality rates with medical record-derived estimates, the correlation coefficient was 0.86 (Standard Error = 0.032). Conclusions/Significance An administrative claims-based model for profiling hospitals for pneumonia mortality performs consistently over several years and produces hospital estimates close to those using a medical record model.

    PubMed Central

    2014-01-01

    Background Securing high-quality mortality statistics requires systematic evaluation of all trauma deaths. We examined the proportion of trauma patients dying within 30 days from causes not related to the injury and the impact of exclusion of patients dead on arrival on 30-day trauma mortality. We also defined the demographics, injury characteristics, cause of death and time to death in patients admitted to our trauma center who died within 30 days, between 2007-2011. Methods Demographics, injury characteristics, status alive/dead on arrival, cause of death and time to death of all patients were reviewed. Deaths were analyzed based on injury mechanism (penetrating, blunt trauma and low energy blunt trauma) and cause of death (traumatic brain injury (TBI), hemorrhage, organ dysfunction and other/unknown). Results Of the 7422 admissions, 343 deaths were identified of which 36 (10.5%) involved causes not related to the injury. The overall age was 71 years, Injury Severity Score (ISS) 29 and time to death 24 hours (all medians). Fifty-four patients (17.6%) were dead on arrival. Exclusion of patients dead on arrival reduced the overall mortality rate (P < 0.05) and median ISS (P < 0.05) and increased median age (P < 0.01) and time to death (P < 0.001). Injury mechanism was penetrating trauma in 7.5%, blunt trauma in 56.0%, and low energy blunt trauma in 36.5%. TBI accounted for 58.6%; hemorrhage 16.3%, organ dysfunction 15.0%, and other/unknown for 10.1% of the deaths. Patients who died after low energy blunt trauma were older, had lower ISS and longer time to death compared to those who died after penetrating and blunt trauma (all P < 0.01). Conclusions Clinical review of all trauma deaths was essential to interpret mortality. Thirty-day trauma mortality included 10.5% deaths not directly related to the injury and the exclusion of patients dead on arrival significantly affected the unadjusted mortality rate, ISS, median age and time to death

    Purpose Mortality following bariatric surgery is a rare event in contemporary series, making it difficult for any single center to draw meaningful conclusions as to cause of death. Nevertheless, much of the published mortality data come from single center case series and reviews of administrative databases. These sources tend to produce lower mortality estimates than those obtained from controlled clinical trials. Furthermore, information about the causes of death and how they were determined is not always available. The aim of the present report is to describe in detail all deaths occurring within 30-days of surgery in the Longitudinal Assessment of Bariatric Surgery (LABS). Methods LABS is a 10-center observational cohort study of bariatric surgical outcomes. Data were collected prospectively for bariatric surgeries performed between March 2005 and April 2009. All deaths occurring within 30-days of surgery were identified, and cause of death assigned by an independent Adjudication Subcommittee, blinded to operating surgeon and site. Results 6118 patients underwent primary bariatric surgery. 18 deaths (0.3%) occurred within 30-days of surgery. The most common cause of death was sepsis (33% of deaths), followed by cardiac causes (28%) and pulmonary embolism (17%). For one patient cause of death could not be determined despite examination of all available information. Conclusions This study confirms the low 30-day mortality rate following bariatric surgery. The recognized complications of anastomotic leak, cardiac events, and pulmonary emboli accounted for the majority of 30-day deaths. PMID:21866378

    Objectives To explore changes over time in the 30-day mortality rate for paediatric cardiac surgery and to understand the role of attendant changes in the case mix. Methods, setting and participants Included were: all mandatory submissions to the National Institute of Cardiovascular Outcomes Research (NICOR) relating to UK cardiac surgery in patients aged <16 years. The χ2 test for trend was used to retrospectively analyse the proportion of surgical episodes ending in 30-day mortality and with various case mix indicators, in 10 consecutive time periods, from 2000 to 2010. Comparisons were made between two 5-year eras of: 30-day mortality, period prevalence and mean age for 30 groups of specific operations. Main outcome measure 30-day mortality for an episode of surgical management. Results Our analysis includes 36 641 surgical episodes with an increase from 2283 episodes in 2000 to 3939 in 2009 (p<0.01). The raw national 30-day mortality rate fell over the period of review from 4.3% (95% CI 3.5% to 5.1%) in 2000 to 2.6% (95% CI 2.2% to 3.0%) in 2009/2010 (p<0.01). The case mix became more complex in terms of the percentage of patients <2.5 kg (p=0.05), with functionally univentricular hearts (p<0.01) and higher risk diagnoses (p<0.01). In the later time era, there was significant improvement in 30-day mortality for arterial switch with ventricular septal defect (VSD) repair, patent ductus arteriosus ligation, Fontan-type operation, tetralogy of Fallot and VSD repair, and the mean age of patients fell for a range of operations performed in infancy. Conclusions The raw 30-day mortality rate for paediatric cardiac surgery fell over a decade despite a rise in the national case mix complexity, and compares well with international benchmarks. Definitive repair is now more likely at a younger age for selected infants with congenital heart defects. PMID:25893099

    Human recombinant erythropoietin (EPO) has been shown to exert neuroprotective effects following both vascular and mechanical brain injury. Previously, we showed that behavioral symptoms associated with mechanical lesions of the hippocampus are nearly abolished due to EPO treatment. In these studies, the EPO administration took place simultaneously with the infliction of brain injury and the rehabilitation training started 6-7 days postoperatively. In the present study, we tested whether the therapeutic effect of EPO on the acquisition of an allocentric eight-arm radial maze spatial task also manifests itself if the rehabilitative training is postponed. Postoperatively, the animals were left without any specific stimulation for 30 days. The current results show an improved behavioral performance of the EPO-treated lesioned group relative to the saline-treated lesioned group, and confirm EPO's therapeutic effect even in case of postponed rehabilitation. However, compared to the control group, the EPO-treated lesioned group demonstrated an impaired task acquisition. All subjects eventually recovered functionally. Subsequently, the animals were given behavioral challenges during which the cue constellation in the room was changed. The challenges revealed that, although the EPO-treated lesion group had achieved the same level of task proficiency as the control group, the cognitive mechanisms mediating the task performance in the EPO-treated lesion group (as well as in the saline-treated lesion group) were dissimilar from those mediating the task in the control group. Both the EPO-treated and the saline-treated lesion group demonstrated an increased dependency on the original cue configuration. PMID:17970627

The prognostic significance of early readmission is not fully understood. The objective of our study was to estimate the mortality risk associated with readmission for acute exacerbation within 30 days of discharge in COPD patients. Methods The cohort (n = 378) was divided into patients readmitted (n = 68) and not readmitted (n = 310) within 30 days of discharge. Clinical, laboratory, microbiological, and severity data were evaluated at admission and during hospital stay, and mortality data were recorded at four time points during follow-up: 30 days, 6 months, 1 year and 3 years. Results Patients readmitted within 30 days had poorer lung function, worse dyspnea perception and higher clinical severity. Two or more prior AECOPD (HR, 2.47; 95% CI, 1.51–4.05) was the only variable independently associated with 30-day readmission. The mortality risk during the follow-up period showed a progressive increase in patients readmitted within 30 days in comparison to patients not readmitted; moreover, 30-day readmission was an independent risk factor for mortality at 1 year (HR, 2.48; 95% CI, 1.10–5.59). In patients readmitted within 30 days, the estimated absolute increase in the mortality risk was 4% at 30 days (number needed to harm NNH, 25), 17% at 6-months (NNH, 6), 19% at 1-year (NNH, 6) and 24% at 3 years (NNH, 5). Conclusion In conclusion a readmission for AECOPD within 30 days is associated with a progressive increased long-term risk of death. PMID:26943928

    Background The current risk model for percutaneous coronary intervention (PCI) in the UK is based on outcomes of patients treated in a different era of interventional cardiology. This study aimed to create a new model, based on a contemporary cohort of PCI treated patients, which would: predict 30 day mortality; provide good discrimination; and be well calibrated across a broad risk-spectrum. Methods and results The model was derived from a training dataset of 336,433 PCI cases carried out between 2007 and 2011 in England and Wales, with 30 day mortality provided by record linkage. Candidate variables were selected on the basis of clinical consensus and data quality. Procedures in 2012 were used to perform temporal validation of the model. The strongest predictors of 30-day mortality were: cardiogenic shock; dialysis; and the indication for PCI and the degree of urgency with which it was performed. The model had an area under the receiver operator characteristic curve of 0.85 on the training data and 0.86 on validation. Calibration plots indicated a good model fit on development which was maintained on validation. Conclusion We have created a contemporary model for PCI that encompasses a range of clinical risk, from stable elective PCI to emergency primary PCI and cardiogenic shock. The model is easy to apply and based on data reported in national registries. It has a high degree of discrimination and is well calibrated across the risk spectrum. The examination of key outcomes in PCI audit can be improved with this risk-adjusted model. PMID:26942330

    Introduction: European system for cardiac operative risk evaluation (EuroSCORE) is a valuable tool in control of the quality of cardiac surgery. However, the validity of the risk score for the individual patient may be questioned. The present study was carried out to investigate whether the continued fall in short-term mortality reflects an actual improvement in late mortality, and subsequently, to investigate EuroSCORE as predictor of 1-year mortality. Methods: A population-based cohort study of 25,602 patients from a 12-year period from three public university hospitals undergoing coronary artery bypass grafting (CABG) or valve surgery. Analysis was carried out based on EuroSCORE, age and co-morbidity factors (residual EuroSCORE). Results: During the period the average age increased from 65.1 ± 10.0 years to 68.9 ± 10.7 years (P < 0.001, one-way ANOVA), and the number of females increased from 26.0% to 28.2% (P = 0.0012, Chi-square test). The total EuroSCORE increased from 4.67 to 5.68 while the residual EuroSCORE decreased from 2.64 to 1.83. Thirty-day mortality decreased from 4.07% in 1999–2000 to 2.44% in 2011–2012 (P = 0.0056; Chi-square test), while 1-year mortality was unchanged (6.50% in 1999–2000 vs. 6.25% in 2011–2012 [P = 0.8086; Chi-square test]). Discussion: The study demonstrates that both co-morbidity and age has a great impact on 30-day mortality. However, with time the impact of co-morbidity seems less. Thus, age is more important than co-morbidity in late mortality. The various developments in short and long-term mortality are not readily explained. Conclusion: Although 30-day mortality of CABG and valve surgery patients has decreased during the 12-year period, the 1-year mortality remains the same. PMID:25849679

    Background. Cholesterol lowering drugs HMG-CoA reductase inhibitors (statins) and PPARα activators (fibrates) have been shown to reduce host inflammation via non-disease specific immunomodulatory mechanisms. Recent studies suggest that commonly prescribed drugs in general practice, statins and fibrates, may be beneficial in influenza-like illness related mortality. This retrospective cohort study examines the association between two lipid lowering drugs, statins and fibrates, and all-cause 30-day mortality following a medically attended acute respiratory illness (MAARI). Methods. Primary care patient data were retrospectively extracted from the UK Clinical Practice Research Datalink (CPRD) database. The sample comprised 201,179 adults aged 30 years or older experiencing a MAARI episode. Patient exposure to statins or fibrates was coded as separate dichotomous variables and deemed current if the most recent GP prescription was issued in the 30 days prior to MAARI diagnosis. Multivariable logistic regression and Cox regression were used for analyses. Adjustment was carried out for chronic lung disease, heart failure, metformin and glitazones, comorbidity burden, socio-demographic and lifestyle variables such as smoking status and body mass index (BMI). Statistical interaction tests were carried out to check for effect modification by gender, body mass index, smoking status and comorbidity. Results. A total of 1,096 (5%) patients died within the 30-day follow up period. Of this group, 213 (19.4%) were statin users and 4 (0.4%) were fibrate users. After adjustment, a significant 35% reduction in odds [adj OR; 0.65 (95% CI [0.52–0.80])] and a 33% reduction in the hazard [adj HR: 0.67 (95% CI [0.55–0.83])] of all-cause 30-day mortality following MAARI was observed in statin users. A significant effect modification by comorbidity burden was observed for the association between statin use and MAARI-related mortality. Fibrate use was associated with a non

    Background Despite the increased acceptance of failure-to-rescue (FTR) as an important patient safety indicator (defined as the percentage of deaths among surgical patients with treatable complications), there has not been any large epidemiological study reporting FTR in an Australian setting nor any evaluation on its suitability as a performance indicator. Methods We conducted a population-based study on elective surgical patients from 82 public acute hospitals in New South Wales, Australia between 2002 and 2009, exploring the trends and variations in rates of hospital complications, FTR and 30-day mortality. We used Poisson regression models to derive relative risk ratios (RRs) after adjusting for a range of patient and hospital characteristics. Results The average rates of complications, FTR and 30-day mortality were 13.8 per 1000 admissions, 14.1% and 6.1 per 1000 admission, respectively. The rates of complications and 30-day mortality were stable throughout the study period however there was a significant decrease in FTR rate after 2006, coinciding with the establishment of national and state-level peak patient safety agencies. There were marked variations in the three rates within the top 20% of hospitals (best) and bottom 20% of hospitals (worst) for each of the four peer-hospital groups. The group comprising the largest volume hospitals (principal referral/teaching hospitals) had a significantly higher rate of FTR in comparison to the other three groups of smaller-sized peer hospital groups (RR = 0.78, 0.57, and 0.61, respectively). Adjusted rates of complications, FTR and 30-day mortality varied widely for individual surgical procedures between the best and worst quintile hospitals within the principal referral hospital group. Conclusions The decrease in FTR rate over the study period appears to be associated with a wide range of patient safety programs. The marked variations in the three rates between- and within- peer hospital groups highlight the

    2009-01-01

    Objective The purpose of this study was to identify independent predictors of mortality and functional recovery in patients with primary intracerebral hemorrhage (PICH) and to improve functional outcome in these patients. Methods Data were collected retrospectively on 585 patients with supratentorial PICH admitted to the Stroke Unit at our hospital between 1st January 2004 and the 31st July 2008. Using multivariate logistic regression analysis, the associations between all selected variables and 30-day mortality and 90-day functional recoveries after PICH was evaluated. Results Ninety-day functional recovery was achieved in 29.1% of the 585 patients and 30-day mortality in 15.9%. Age (OR=7.384, p=0.000), limb weakness (OR=6.927, p=0.000), and hematoma volume (OR=5.293, p=0.000) were found to be powerful predictors of 90-day functional recovery. Furthermore, initial consciousness (OR=3.013, p=0.014) hematoma location (lobar, OR=2.653, p=0.003), ventricular extension of blood (OR=2.077, p=0.013), leukocytosis (OR=2.048, p=0.008), alcohol intake (drinker, OR=1.927, p=0.023), and increased serum aminotransferase (OR=1.892, p=0.035) were found to be independent predictors of 90-day functional recovery after PICH. On the other hand, a pupillary abnormality (OR=4.532, p=0.000) and initial unconsciousness (OR=3.362, p=0.000) were found to be independent predictors of 30-day mortality after PICH. Conclusion The predictors of mortality and functional recovery after PICH identified during this analysis may assist during clinical decision-making, when advising patients or family members about the prognosis of PICH and when planning intervention trials.

    Background Troponin is the preferred biomarker for risk stratification in non-ST-elevation ACS. The incremental prognostic utility of the initial magnitude of troponin elevation and its value in conjunction with ST segment resolution (STRes) in STEMI is less well-defined. Methods Troponin T (TnT) was measured in 1250 patients at presentation undergoing fibrinolysis for STEMI in CLARITY-TIMI 28. STRes was measured at 90 minutes. Multivariable logistic regression was used to examine the independent association between TnT levels, STRes, and 30-day cardiovascular (CV) mortality. Results Patients were classified into undetectable TnT at baseline (n=594), detectable but below the median of 0.12 ng/ml (n=330), and above the median (n=326). Rates of 30-day CV death were 1.5%, 4.5%, and 9.5% respectively (P<0.0001). Compared with those with undetectable levels and adjusting for baseline factors, the odds ratios for 30-day CV death were 4.56 (1.72-12.08, P=0.002) and 5.81 (2.29-14.73, P=0.0002) for those below and above the median, respectively. When combined with STRes, there was a significant gradient of risk, and in a multivariable model both baseline TnT (P=0.004) and STRes (P=0.003) were significant predictors of 30-day CV death. The addition of TnT and STRes to clinical risk factors significantly improved the C-statistic (0.86 to 0.90, P=0.02) and the integrated discriminative improvement 7.1% (P=0.0009). Conclusions Baseline TnT and 90-minute STRes are independent predictors of 30-day CV death in patients with STEMI. Use of these two simple, readily available tools can aid clinicians in early risk stratification. PMID:20569707

    Preventing 30-day readmissions to hospitals is a top priority in the era of health care reform. New regulations will be costly to health care facilities because of payment guidelines. The most frequently readmitted medical conditions are acute myocardial infarction, heart failure, and pneumonia. The transition from the hospital and into the home has been classified as a vulnerable time for many patients. During this time of transition patients may fail to fully understand their discharge instructions. Ineffective communication, low health literacy, and compliance issues contribute to readmissions. Telehealth and the use of technology may be used to prevent some readmissions. PMID:25680492

    Background The purpose of this study was to assess the validity of patient administrative data (PAS) for calculating 30-day mortality after hip fracture as a quality indicator, by a retrospective study of medical records. Methods We used PAS data from all Norwegian hospitals (2005–2009), merged with vital status from the National Registry, to calculate 30-day case-mix adjusted mortality for each hospital (n = 51). We used stratified sampling to establish a representative sample of both hospitals and cases. The hospitals were stratified according to high, low and medium mortality of which 4, 3, and 5 hospitals were sampled, respectively. Within hospitals, cases were sampled stratified according to year of admission, age, length of stay, and vital 30-day status (alive/dead). The final study sample included 1043 cases from 11 hospitals. Clinical information was abstracted from the medical records. Diagnostic and clinical information from the medical records and PAS were used to define definite and probable hip fracture. We used logistic regression analysis in order to estimate systematic between-hospital variation in unmeasured confounding. Finally, to study the consequences of unmeasured confounding for identifying mortality outlier hospitals, a sensitivity analysis was performed. Results The estimated overall positive predictive value was 95.9% for definite and 99.7% for definite or probable hip fracture, with no statistically significant differences between hospitals. The standard deviation of the additional, systematic hospital bias in mortality estimates was 0.044 on the logistic scale. The effect of unmeasured confounding on outlier detection was small to moderate, noticeable only for large hospital volumes. Conclusions This study showed that PAS data are adequate for identifying cases of hip fracture, and the effect of unmeasured case mix variation was small. In conclusion, PAS data are adequate for calculating 30-day mortality after hip-fracture as a quality

    Purpose To identify the factors affecting 30-day postoperative complications and 1-year mortality after surgery for colorectal cancer in octogenarians and nonagenarians. Methods Between 2005 and 2014, a total of 204 consecutive patients aged ≥80 years who underwent major colorectal surgery were included. Results One hundred patients were male (49%) and 52 patients had American Society of Anesthesiologists (ASA) score ≥3 (25%). Combined surgery was performed in 32 patients (16%). Postoperative complications within 30 days after surgery occurred in 54 patients (26%) and 30-day mortality occurred in five patients (2%). Independent risk factors affecting 30-day postoperative complications were older age (≥90 years, hazard ratio [HR] with 95% confidence interval [CI] =4.95 [1.69−14.47], P=0.004), an ASA score ≥3 (HR with 95% CI =4.19 [1.8−9.74], P=0.001), performance of combined surgery (HR with 95% CI =3.1 [1.13−8.46], P=0.028), lower hemoglobin level (<10 g/dL, HR with 95% CI =7.56 [3.07−18.63], P<0.001), and lower albumin level (<3.4 g/dL, HR with 95% CI =3.72 [1.43−9.69], P=0.007). An ASA score ≥3 (HR with 95% CI =2.72 [1.15−6.46], P=0.023), tumor-node-metastasis (TNM) stage IV (HR with 95% CI =3.47 [1.44−8.39], P=0.006), and occurrence of postoperative complications (HR with 95% CI =4.42 [1.39−14.09], P=0.012) were significant prognostic factors for 1-year mortality. Conclusion Patient-related factors (older age, higher ASA score, presence of anemia, and lower serum albumin) and procedure-related factors (performance of combined surgical procedure) increased postoperative complications. Avoidance of 30-day postoperative complications may decrease 1-year mortality. PMID:27279741

    Abstract The purpose of this article is to evaluate the American Society of Anesthesiologists Physical Status (ASA PS) and the Charlson comorbidity index (CCI) for the prediction of postoperative mortality. The ASA PS has been suggested to be equally good as the CCI in predicting postoperative outcome. However, these scores have never been compared in a broad surgical population. We conducted a retrospective cohort study in a German tertiary care university hospital. Predictive accuracy was compared using the area under the receiver-operating characteristic curves (AUROC). In a post hoc approach, a regression model was fitted and cross-validated to estimate the association of comorbidities and intraoperative factors with mortality. This model was used to improve prediction by recalibrating the CCI for surgical patients (sCCIs) and constructing a new surgical mortality score (SMS). The data of 182,886 patients with surgical interventions were analyzed. The CCI was superior to the ASA PS in predicting postoperative mortality (AUROCCCI 0.865 vs AUROCASAPS 0.833, P < 0.001). Predictive quality further improved after recalibration of the sCCI and construction of the new SMS (AUROCSMS 0.928 vs AUROCsCCI 0.896, P < 0.001). The SMS predicted postoperative mortality especially well in patients never admitted to an intensive care unit. The newly constructed SMS provides a good estimate of patient's risk of death after surgery. It is capable of identifying those patients at especially high risk and may help reduce postoperative mortality. PMID:25715258

    Complication rates and postoperative mortality were studied in 1010 consecutive patients entered into the Norwegian Stomach Cancer Trial. Twenty-eight per cent of the patients had one or more complications (31% of the men and 21% of the women). General complications (pneumonia, thromboembolic, and cardiac) were most frequent. The postoperative mortality rate for resected patients was 8.3% (63 of 763). Complication and mortality rates were highest for proximal resections (52% and 16%) followed by total gastrectomy (38% and 8%), subtotal resection (28% and 10%), and distal resection (19% and 7%). By logistic regression analysis it was found that age, sex, operative procedure, prophylactic antibiotics, and splenectomy were significantly related to postoperative complications. The odds ratio for complication for men versus women was 1.75: for no antibiotics versus antibiotic prophylaxis it was 2.5. Relative to distal resection the odds ratio for complications after subtotal resection was 2.2, for total gastrectomy was 3.9, and for proximal resection was 7.6. Age and sex were the only factors that affected operative mortality. The odds ratio for mortality for men versus women was 2.3. The odds ratio for operative mortality was 2.2 when the age of the patient increased with 10 years. PMID:3337564

    The impact of venous thromboembolism (VTE) after hepatectomy on patient morbidity, mortality, and resource usage remains poorly defined. Better understanding of thromboembolic complications is needed to improve perioperative management and overall outcomes. About 3973 patients underwent hepatectomy within NSQIP between 2005 and 2008. Patient characteristics, operative features, and postoperative correlates of VTE were compared with identify risk factors for VTE and to assess its overall impact on postoperative outcomes. Overall incidence of postoperative VTE was 2.4 per cent. Risk factors for postoperative VTE included older age, male gender, compromised functional status, degree of intraoperative blood transfusion, preoperative albumin level (all P < 0.05), and extent of hepatectomy (P = 0.004). Importantly, major postoperative complications, including acute renal failure, pneumonia, sepsis, septic shock, reintubation, prolonged ventilation, cardiac arrest, and reoperation were all associated with higher rates of VTE (all P < 0.05). Operative mortality was increased among patients with VTE (6.5% vs 2.4%, P = 0.03), and patients with VTE had a 2-fold increase in hospital length of stay (12.0 vs 6.0 days, P < 0.001). Postoperative VTE remains a significant source of morbidity, mortality, and increased resource usage after hepatectomy in the United States. Routine aggressive VTE prophylaxis measures are imperative to avoid development of VTE among patients requiring hepatectomy. PMID:26736156

    Anterior cervical fusion (ACF) after discectomy and/or corpectomy is a common procedure with traditionally good patient outcomes. Though typically mild, postoperative dysphagia can result in significant patient morbidity. In this study, we examine the relationship between postoperative dysphagia and in-hospital outcomes, readmissions, and overall costs. The University HealthSystem Consortium (UHC) database was utilized to perform a retrospective cohort study of all adults who underwent a principal procedure of ACF of the anterior column (International Classification of Diseases, Ninth Revision [ICD-9] procedure code 81.02) between 2013 and 2015. Patients with a diagnosis of dysphagia (ICD-9 78720-78729) were compared to those without. Patient demographics, length of stay, in-hospital mortality, 30-day readmissions, and direct costs were recorded. A total of 49,300 patients who underwent ACF were identified. Mean age was 54.5years and 50.2% were male. Dysphagia was documented in 3,137 patients (6.4%) during their hospital stay. Patients with dysphagia had an average 2.1 comorbidities, while patients without dysphagia had 1.5 (p<0.01). Mean length of stay was 6.38days in patients with dysphagia, and 2.13days in those without (p<0.01). In-hospital mortality was 0.10% in patients without dysphagia, and 0.61% in those with dysphagia (p<0.01). Direct costs were $13,099 in patients without dysphagia, and $21,245 in those with dysphagia (p<0.01). Thirty-day readmission rate was 2.9% in patients without dysphagia, and 5.3% in those with dysphagia (p=0.01). In summary, dysphagia in patients who undergo ACF correlates with significantly increased length of stay, 30-day readmissions, and in-hospital mortality. Direct costs are similarly increased as a result. PMID:27234612

    IMPORTANCE Antiretroviral therapy (ART) has converted human immunodeficiency virus (HIV) infection into a chronic condition, and patients now undergo a variety of surgical procedures, but current surgical outcomes are inadequately characterized. OBJECTIVE To compare 30-day postoperative mortality in patients with HIV infection receiving ART with the rates in uninfected individuals. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of nationwide electronic medical record data from the US Veterans Health Administration Healthcare System, October 1, 1996, to September 30, 2010. Common inpatient surgical procedures were grouped using the Healthcare Cost and Utilization Project Clinical Classification System to match HIV-infected and uninfected patients in a 1:2 ratio. Data on 1641 patients with HIV infection receiving combination ART who were undergoing inpatient surgery were compared with data on 3282 procedure-matched, uninfected comparators. Poisson regression models of 30-day postoperative mortality were adjusted for procedure year, age, Charlson Comorbidity Index score, hemoglobin level, albumin level, HIV infection, CD4 cell count, and HIV-1 RNA level. MAIN OUTCOMES AND MEASURES All-cause 30-day postoperative mortality. RESULTS The most common procedures in both groups were cholecystectomy (10.5%), hip arthroplasty (10.5%), spine surgery (9.8%), herniorrhaphy (7.4%), and coronary artery bypass grafting (7.0%). In patients with HIV infection, CD4 cell distributions were 80.0% with 200/µL or more, 16.3% with 50/µL to 199/µL, and 3.7% with less than 50/µL; 74.1% of patients with HIV infection had undetectable HIV-1 RNA. Human immunodeficiency virus infection was associated with higher 30-day postoperative mortality compared with the mortality in uninfected patients (3.4% [56 patients]) vs 1.6% [53]); incidence rate ratio [IRR], 2.11; 95% CI, 1.41–3.17; P < .001). CD4 cell count was inversely associated with mortality, but HIV-1 RNA provided no

    Well-known and suitable instruments for surgical audit are the POSSUM and P-POSSUM scoring systems. But these scores have not been well validated across the countries. The objective of the present study was to assess the predictive value of scores for colorectal surgery in France. Patients operated on for colorectal malignant or diverticular diseases, whether electively or on emergency basis, within a 4-month period were included in a prospective multicenter study conducted by the French Association for Surgery (Association Française de Chirurgie, AFC). The main outcome measure was postoperative in-hospital mortality. Independent factors leading to death were assessed by multivariate logistic regression analysis (AFC-index). The ratio of expected versus observed deaths was calculated, and the predictive value of the POSSUM and P-POSSUM scores were analyzed by the receiver operating characteristic (ROC) curve. A total of 1426 patients were included. The in-hospital death rate was 3.4%. Four independent preoperative factors (AFC-index) have been found: emergency surgery, loss of more than 10% of weight, neurological disease history, and age > 70 years. POSSUM had a poor predictive value; it overestimated postoperative death in all cases. P-POSSUM had a good predictive value, except for elective surgery, where it overestimated postoperative death twofold. The predictive value of the AFC-index was also good. It had the same sensitivity and specificity as the P-POSSUM. POSSUM has not been validated in France in the field of colorectal surgery. P-POSSUM was as predictive as the AFC-index which is a simpler instrument based on four clinical parameters (without any mathematical formulas). PMID:16369701

    OBJECT Surgery for subdural hematoma (SDH) is a commonly performed neurosurgical procedure. This study identifies patient characteristics associated with adverse outcomes and prolonged length of stay (LOS) in patients who underwent surgical treatment for SDH. METHODS All patients in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) who were treated via craniotomy or craniectomy for SDH between 2005 and 2012 were identified. Patient demographics, comorbidities, and 30-day outcomes were described. Multivariate regression was used to identify predictors of adverse events. RESULTS A total of 746 surgical procedures performed for SDH were identified and analyzed. Patients undergoing this procedure were 64% male with an average age (± SD) of 70.9 ± 14.1 years. The most common individual adverse events were death (17%) and intubation for more than 48 hours (19%). In total, 34% experienced a serious adverse event other than death, 8% of patients returned to the operating room (OR), and the average hospital LOS was 9.8 ± 9.9 days. In multivariate analysis, reduced mortality was associated with age less than 60 years (relative risk [RR] = 0.47, p = 0.017). Increased mortality was associated with gangrene (RR = 3.5, p = 0.044), ascites (RR = 3.00, p = 0.006), American Society of Anesthesiologists (ASA) Class 4 or higher (RR = 2.34, p = 0.002), coma (RR = 2.25, p < 0.001), and bleeding disorders (RR = 1.87, p = 0.003). Return to the OR was associated with pneumonia (RR = 3.86, p = 0.044), male sex (RR = 1.85, p = 0.015), and delirium (RR = 1.75, p = 0.016). Serious adverse events were associated with ventilator dependence preoperatively (RR = 1.86, p < 0.001), dialysis (RR = 1.44, p = 0.028), delirium (RR = 1.40, p = 0.005), ASA Class 4 or higher (RR = 1.36, p = 0.035), and male sex (RR = 1.29, p = 0.037). Similarly, LOS was increased in ventilator dependent patients by 1.56-fold (p = 0.002), in patients with ASA Class 4 or higher by

    Summary Introduction Augmentation enterocystoplasty and appendicovesicostomy are complex pediatric urologic procedures. Although there is literature identifying long-term outcomes in these patients, the reporting of short-term postoperative outcomes has been limited by small numbers of cases and lack of prospective data collection. Here we report 30-day outcomes from the first nationally based, prospectively assembled cohort of pediatric patients undergoing these procedures. Objective To determine 30-day complication, readmission and reoperation after augmentation enterocystoplasty and appendicovesicostomy in a large national sample of pediatric patients, and to explore the association between preoperative and intraoperative characteristics and occurrence of any 30-day event. Study design We queried the 2012 and 2013 American College of Surgeons National Surgical Quality Improvement Program Pediatric database (ACS-NSQIPP) for all patients undergoing augmentation enterocystoplasty and/or appendicovesicostomy. Surgical risk score was classified on a linear scale using a validated pediatric-specific comorbidity score. Intraoperative characteristics and postoperative 30-day events were reported from prospectively collected data. A composite measure of complication, readmission and/or reoperation was used as primary outcome for the multivariate logistic regression. Results There were 461 patients included in the analysis: 245 had appendicovesicostomy, 97 had augmentation enterocystoplasty and 119 had both procedures. There were a total of 110 NSQIP complications seen in 87 patients. The most common complication was urinary tract infection(see Table for 30-day outcomes by patient). The composite measure of any 30-day event was seen in 27.8% of the cohort and this was associated with longer operative time, increased number of procedures done at time of primary surgical procedure and higher surgical risk score. Discussion The ACS-NSQIPP provides a tool to examine short

    Context: Appropriate selection of aging patient who fit for cancer surgery is an art-of-state. Objectives: This study aimed to identify predictive factors pertinent to 3-month postoperative mortality in geriatric cancer patients. Methods: A total of 8,425 patients over 70 years old with solid cancer received radical surgery between 2007 and 2012 at four affiliated hospitals of the Chang Gung Memorial Hospital were included. The clinical variables of patients who died within 3 months post-surgery were analyzed retrospectively. Recursive partitioning analysis (RPA) was performed by randomly selecting 50% of the patients (testing set) to identify specific groups of patients with the lowest and highest probability of 3-month postoperative mortality. The remaining 50% were used as validation set of the model. Results: Patients' gender, Eastern Cooperative Oncology Group performance (ECOG scale), Charlson comorbidity index (CCI), American Society of Anesthesiologist physical status, age, tumor staging, and mode of admission were independent variables that predicted 3-month postoperative mortality. The RPA model identified patients with an ECOG scale of 0-2, localized tumor stage, and a CCI of 0-2 as having the lowest probability of 3-month postoperative mortality (1.1% and 1.3% in the testing set and validation set, respectively). Conversely, an ECOG scale of 3-4 and a CCI >2 were associated with the highest probability of 3-month postoperative mortality (55.2% and 47.8% in the testing set and validation set, respectively). Conclusion: We identified ECOG scale and CCI score were the two most influencing factors that determined 3-month postoperative mortality in geriatric cancer patients. PMID:26722355

    The purpose of this review was to assess whether neoadjuvant chemotherapy and chemoradiotherapy (CRT) result in differential postoperative morbidity and mortality as compared with pancreatic tumor resection surgery alone. Using PRISMA guidelines and the PubMed search engine, we reviewed all prospective phase II trials of neoadjuvant chemotherapy and CRT for pancreatic cancer that examined postoperative morbidities and mortalities. A total of 30 articles were identified, collated, and analyzed. Risks of postoperative complications vary based on trial. With surgery alone, the most common postoperative complications included delayed gastric emptying (DGE) (17% to 24%), pancreatic fistula (10% to 20%), anastomotic leaks (0% to 15%), postoperative bleeding (2% to 13%), and infections/sepsis (17% to 20%). With surgery alone, the mortality was <5%. Neoadjuvant chemotherapy showed comparable fistula rates (3% to 4%), leaks (3% to 11%), infection (3% to 7%), with mortality 0% to 4% in all but 1 study. CRT for resectable/borderline resectable patients also showed comparable complication rates: DGE (6% to 15%), fistulas (2% to 3%), leaks (3% to 7%), bleeding/hemorrhage (2% to 13%), infections/sepsis (3% to 19%), with 9/13 studies showing a mortality of ≤4%. As compared with initially borderline/resectable tumors, CRT for initially unresectable tumors (despite less data) showed higher complication rates: DGE (13% to 33%), fistulas (3% to 25%), infections/sepsis (3% to 16%). However, the confounding factor of the potentially higher tumor burden as an associative agent remains. The only parameters slightly higher than historical surgery-only complication rates were leaks and bleeding/hemorrhage (13% to 20%). Mortality rates in these patients were consistently 0%, with 2 outliers. Hence, neoadjuvant chemotherapy/CRT is safe from a postoperative complication standpoint, without significant increases in complication rates compared with surgery alone. Resectable and borderline

    Purpose: To assess the association between dosimetric factors of the lung and incidence of intra- and postoperative mortality among esophageal cancer (EC) patients treated with neoadjuvant radiochemotherapy (N-RCT) followed by surgery (S). Methods and Materials: Inclusion criteria were: age < 85 years, no distant metastases at the time of diagnosis, no induction chemotherapy, conformal radiotherapy, total dose ≤ 50.4 Gy, and available dose volume histogram (DVH) data. One-hundred thirty-five patients met our inclusion criteria. Median age was 62 years. N-RCT consisted of 36 - 50.4 Gy (median 45 Gy), 1.8 - 2 Gy per fraction. Concomitant chemotherapy consisted of 5-Fluoruracil (5-FU) and cisplatin in 113 patients and cisplatin and taxan-derivates in 15 patients. Seven patients received a single cytotoxic agent. In 130 patients an abdominothoracal and in 5 patients a transhiatal resection was performed. The following dosimetric parameters were generated from the total lung DVH: mean dose, V5, V10, V15, V20, V30, V40, V45 and V50. The primary endpoint was the rate of intra- and postoperative mortality (from the start of N-RCT to 60 days after surgical resection). Results: A total of ten postoperative deaths (7%) were observed: 3 within 30 days (2%) and 7 between 30 and 60 days after surgical intervention (5%); no patient died during the operation. In the univariate analysis, weight loss (≥10% in 6 months prior to diagnosis, risk ratio: 1.60, 95%CI: 0.856-2.992, p=0.043), Eastern Cooperative Oncology Group-performance status (ECOG 2 vs. 1, risk ratio: 1.931, 95%CI: 0.898-4.150, p=0.018) and postoperative pulmonary plus non-pulmonary complications (risk ratio: 2.533, 95%CI: 0.978-6.563, p=0.004) were significantly associated with postoperative mortality. There was no significant association between postoperative mortality and irradiated lung volumes. Lung V45 was the only variable which was significantly associated with higher incidence of postoperative pulmonary

    Background Medullary thyroid cancer (MTC) is a rare thyroid cancer accounting for 5 % of all thyroid malignancies. The purpose of our study was to design a predictive nomogram for cancer-specific mortality (CSM) utilizing clinical, pathological, and biochemical variables in patients with MTC. Methods MTC patients managed entirely at Memorial Sloan-Kettering Cancer Center between 1986 and 2010 were identified. Patient, tumor, and treatment characteristics were recorded, and variables predictive of CSM were identified by univariable analyses. A multivariable competing risk model was then built to predict the 10-year cancer specific mortality of MTC. All predictors of interest were added in the starting full model before selection, including age, gender, pre- and postoperative serum calcitonin, pre- and postoperative CEA, RET mutation status, perivascular invasion, margin status, pathologic T status, pathologic N status, and M status. Stepdown method was used in model selection to choose predictive variables. Results Of 249 MTC patients, 22.5 % (56/249) died from MTC, whereas 6.4 % (16/249) died secondary to other causes. Mean follow-up period was 87 ± 67 months. The seven variables with the highest predictive accuracy for cancer specific mortality included age, gender, postoperative calcitonin, perivascular invasion, pathologic T status, pathologic N status, and M status. These variables were used to create the final nomogram. Discrimination from the final nomogram was measured at 0.77 with appropriate calibration. Conclusions We describe the first nomogram that estimates cause-specific mortality in individual patients with MTC. This predictive nomogram will facilitate patient counseling in terms of prognosis and subsequent clinical follow up. PMID:25366585

    The aim of this work is provide the results of the surgical treatment of strangulated groin hernias and determine morbidity and mortality risk factors. It is a retrospective study related to the 288 records of patients aged 15 years and more, who underwent emergency surgery for strangulated groin hernia from January 2007 to December 2012. Postoperative evolution was assessed on the morbidity, mortality, and length of hospital stay. Mortality and morbidity risk factors were studied. The statistical analysis was conducted with the chi-square test and Fischer's exact test with a significance level of 5 %. Strangulated groin hernias account for 42.2 % of the overall groin hernia operations conducted during the study period (288/697). Necroses were present in 59 (20.5 %) patients. The mortality rate was 6.2 % (n = 18). Admission time superior or equal to 48 h (p = 0.002), American Society of Anesthesiologists (ASA) class superior or equal to III (p = 0.002), presence of preoperative strangulated groin hernia complication (peritonitis, occlusion, hernia abscesses) (p = 0.001), bowel necrosis (p = 0.000), and bowel resection (p = 0.000) were statistically related to a high risk of death. Forty-two (n = 42) postoperative complications were recorded in 34 (11.8 %) patients. These complications were outnumbered by postoperative parietal suppuration (n = 26) which led to three cases of evisceration. Bowel necrosis was related to a high risk of postoperative complications (p = 0.002). Reoperation was necessary for 13 patients. The length of stay in hospital was 4 days (range between 1 and 28 days). The average follow-up period was 7 months. No recurrence was noticed during this period. Delay in consultation, high ASA class, and moreover, bowel necrosis requiring bowel resection are the factors of unfavorable postoperative results. Groin hernias are an avoidable death cause provided that early treatment of strangulated hernias and

    Background Hospital readmission within 30-days of an index hospitalization is receiving increased scrutiny as a marker of poor quality patient care. This study identifies factors associated with 30-day readmission following General Surgery procedures. Study Design Using standard National Surgical Quality Improvement Project (NSQIP) protocol, preoperative, intraoperative, and postoperative outcomes were collected on patients undergoing inpatient General Surgery procedures at a single academic center between 2009 and 2011. Data were merged with our institutional clinical data warehouse to identify unplanned 30-day readmissions. Demographics, comorbidities, type of procedure, postoperative complications, and ICD-9 coding data were reviewed for patients who were readmitted. Univariate and multivariate analysis was utilized to identify risk factors associated with 30-day readmission. Results 1442 General Surgery patients were reviewed. 163 (11.3%) were readmitted within 30 days of discharge. The most common reasons for readmission were gastrointestinal complaint/complication (27.6%), surgical infection (22.1%), and failure to thrive/malnutrition (10.4%). Comorbidities associated with risk of readmission included disseminated cancer, dyspnea, and preoperative open wound (p<0.05 for all variables). Surgical procedures associated with higher rates of readmission included pancreatectomy, colectomy, and liver resection. Postoperative occurrences leading to increased risk of readmission were blood transfusion, postoperative pulmonary complication, wound complication, sepsis/shock, urinary tract infection, and vascular complications. Multivariable analysis demonstrates that the most significant independent risk factor for readmission is the occurrence of any postoperative complication (OR 4.20, 95% CI 2.89–6.13). Conclusions Risk factors for readmission after General Surgery procedures are multi-factorial; however, postoperative complications appear to drive readmissions in

    Background An individual's socioeconomic status (SES) is associated with health outcomes and mortality, yet it is unknown whether accounting for SES can improve risk-adjustment models for 30-day outcomes among Centers for Medicare & Medicaid Services (CMS) beneficiaries hospitalized with heart failure (HF). Methods and Results We linked clinical data on hospitalized HF patients in the Get With The Guidelines®-HF™ database (01/2005–12/2011) with CMS claims and county-level SES data from the 2012 Area Health Resources Files. We compared the discriminatory capabilities of multivariable models that adjusted for SES, patient, and/or hospital characteristics to determine whether county-level SES data improved prediction or changed hospital rankings for 30-day all-cause mortality and rehospitalization. After adjusting for patient and hospital characteristics, median household income (per $5,000 increase) was inversely associated with odds of 30-day mortality (OR 0.97, 95% CI 0.95–1.00, p=0.032), and the percentage of persons with at least a high school diploma (per 5 unit increase) was associated with lower odds of 30-day rehospitalization (OR 0.95, 95% CI 0.91–0.99).After adjustment for county-level SES data, relative to whites, Hispanic ethnicity (OR 0.70, 95% CI 0.58, 0.83) and black race (OR 0.57, 95% CI: 0.50–0.65) remained significantly associated with lower 30-day mortality, but had similar 30-day rehospitalization. County-level SES did not improve risk adjustment or change hospital rankings for 30-day mortality or rehospitalization. Conclusions County-level SES data are modestly associated with 30-day outcomes for CMS beneficiaries hospitalized with HF, but do not improve risk adjustment models based on patient characteristics alone.

    ABSTRACT Nowadays, coronary artery bypass grafting (CABG) is considered to be one of the most common surgical procedures. This procedure has been the main topic in many clinical research studies, which have assessed the effect of the procedure on patients’ outcomes. Like other surgical procedures, this procedure is also accompanied by a number of unwanted complications, including those of the respiratory system. Since the respiratory system plays an integral role in defining the clinical outcome of patients, improvements in studies that can assess and predict clinical outcomes of the respiratory system, assume greater importance. There are a number of predictive models which can assess patients in the preoperative period and introduce a number of risk factors, which could be considered as prognostic factors for patients undergoing CABG. The respiratory system is among the clinical systems that are assessed in many prediction scoring systems. This review assesses the main studies which have evaluated the possible risk factors for postoperative respiratory mortality and morbidity, in patients undergoing CABG. PMID:24223339

    Background: The use of induction chemoradiotherapy followed by surgery has been widely used for the treatment of esophageal cancer. The presumed risk of increased postoperative morbidity and mortality with this regimen has led to reluctance to offer this therapy to elderly patients. We compared the perioperative morbidity and mortality of patients 70 years old and older with those of patients younger than 70 who received CRT followed by esophagectomy and sought to identify preoperative risk factors that may predict higher risk of postoperative death or complications. Methods and Materials: We identified 260 patients who underwent preoperative chemoradiotherapy followed by esophagectomy. The association of age with postoperative death and complications was evaluated. The Charlson index, prior cardiac history, and diabetes were identified as preoperative risk factors and were evaluated as potential confounders or effect modifiers. Results: Cardiac disease and the Charlson index were potential modifiers of the effect of age on length of hospital stay (p = 0.08 and p = 0.07, respectively) and postoperative complications (p = 0.1 and p = 0.2) but were not statistically significant. There was a slight nonsignificant decrease in the risk of death in elderly patients after adjustment for the Charlson index (p = 0.2). Conclusion: No significant differences were detected with respect to morbidity and mortality in elderly patients. The presence of cardiac disease, higher scores on the Charlson index, or diabetes did not significantly influence length of stay, postoperative complications, or postoperative death. Given the potential to improve outcomes, this regimen should not be discounted in elderly patients.

    Background Newly developed atrial fibrillation (AF) in patients who have undergone an esophagectomy increases the incidence of postoperative complications. However, the clinical implications of AF have not been fully elucidated in these patients. This retrospective observational study investigated the predictors for AF and the effect of AF on the mortality in esophageal cancer patients undergoing esophagectomy. Methods This study evaluated 583 patients undergoing esophagectomy, from January 2005 to April 2012. AF was defined as newly developed postoperative AF requiring treatment. The risk factors for AF and the association between AF and mortality were evaluated. The long-term mortality was the all-cause mortality, for which the cutoff date was May 31, 2014. Results AF developed in 63 patients (10.8%). Advanced age (odds ratio [OR] 1.099, 95% confidence interval [CI] 1.056–1.144, P < 0.001), preoperative calcium channel blocker (CCB) (OR 2.339, 95% CI 1.143–4.786, P = 0.020), and angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) (OR 0.206, 95% CI 0.067–0.635, P = 0.006) were associated with the incidence of AF. The Kaplan-Meier curve showed a significantly lower survival rate in the AF group compared to the non-AF group (P = 0.045), during a median follow-up of 50.7 months. The multivariable analysis revealed associations between AF and the 1-year mortality (hazard ratio [HR] 2.556, 95% CI 1.430–4.570, P = 0.002) and between AF and the long-term mortality (HR 1.507, 95% CI 1.003–2.266, P = 0.049). Conclusions In esophageal cancer patients, the advanced age and the preoperative medications (CCB, ACEI or ARB) were associated with the incidence of AF. Furthermore, postoperatively developed AF was associated with mortality in esophageal cancer patients after esophagectomy, suggesting that a close surveillance might be required in patients who showed AF during postoperative period.

    Objective: The aim of the present prospective study was to validate externally a 4-item predictive score of mortality after colorectal surgery (the AFC score) by testing its generalizability on a new population. Summary Background Data: We have recently reported, in a French prospective multicenter study, that age older than 70 years, neurologic comorbidity, underweight (body weight loss >10% in <6 months), and emergency surgery significantly increased postoperative mortality after resection for cancer or diverticulitis. Patients and Methods: From June to September 2004, 1049 consecutive patients (548 men and 499 women) with a mean age of 67 ± 14 years, undergoing open or laparoscopic colorectal resection, were prospectively included. The AFC score was validated in this population. We assessed also the predictive value of other scores, such as the “Glasgow” score and the ASA score. To express and compare the predictive value of the different scores, a receiver operating characteristic curve was calculated. Results: Postoperative mortality rate was 4.6%. Variables already identified as predictors of mortality and used in the AFC score were also found to be associated with a high odds ratio in this study: emergency surgery, body weight loss >10%, neurologic comorbidity, and age older than 70 years in a multivariate logistic model. The validity of the AFC score in this population was found very high based both on the Hosmer-Lemeshow goodness of fit test (P = 0.37) and on the area under the ROC curve (0.89). We also found that discriminatory capacity was higher than other currently used risk scoring systems such as the Glasgow or ASA score. Conclusion: The present prospective study validated the AFC score as a pertinent predictive score of postoperative mortality after colorectal surgery. Because it is based on only 4 risk factors, the AFC score can be used in daily practice. PMID:17592296

    Background Surgical patients frequently experience postoperative increases in creatinine levels. The authors hypothesized that even small increases in postoperative creatinine levels are associated with adverse outcomes. Methods The authors examined the association of postoperative changes from preoperative baseline creatinine with all-cause in-hospital mortality and hospital length of stay (HLOS) in a retrospective analysis of surgical patients at a single tertiary care center between January 2006 and June 2012. Results The data of 39,369 surgical patients (noncardiac surgery n = 37,345; cardiac surgery n = 2,024) were analyzed. Acute kidney injury (AKI)—by definition of the Kidney Disease: Improving Global Outcome group—was associated with a five-fold higher mortality (odds ratio [OR], 4.8; 95% CI, 4.1 to 5.7; P < 0.001) and a longer HLOS of 5 days (P < 0.001) after adjusting for age, sex, comorbidities, congestive heart failure, preoperative hemoglobin, preoperative creatinine, exposure to radiocontrast agent, type of surgery, and surgical AKI risk factors. Importantly, even minor creatinine increases (Δcreatinine 25 to 49% above baseline but < 0.3 mg/dl) not meeting AKI criteria were associated with a two-fold increased risk of death (OR, 1.7; 95% CI, 1.3 to 2.4; P < 0.001) and 2 days longer HLOS (P < 0.001). This was more pronounced in noncardiac surgery patients. Patients with minor creatinine increases had a five-fold risk of death (OR, 5.4; 95% CI, 1.5 to 20.3; P < 0.05) and a 3-day longer HLOS (P < 0.01) when undergoing noncardiac surgery. Conclusions Even minor postoperative increases in creatinine levels are associated with adverse outcomes. These results emphasize the importance to find effective therapeutic approaches to prevent or treat even mild forms of postoperative kidney dysfunction to improve surgical outcomes. PMID:26492475

    Background Robotic surgery has emerged as a minimally invasive alternative to traditional laparoscopy. Robotic surgery addresses many of the technical and ergonomic limitations of laparoscopic surgery, but the literature regarding clinical outcomes in colorectal surgery is limited. We sought to compare robotic and laparoscopic colorectal resections with respect to 30-day perioperative outcomes. Methods The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all patients who underwent robotic or laparoscopic colorectal surgery in 2013. We performed a logistic regression analysis to compare intraoperative variables and 30-day outcomes. Results There were 8392 patients who underwent laparoscopic colorectal surgery and 472 patients who underwent robotic colorectal surgery. The robotic cohort had a lower incidence of unplanned intraoperative conversion (9.5% v. 13.7%, p = 0.008). There were no significant differences between robotic and laparoscopic surgery with respect to other intraoperative and postoperative outcomes, such as operative duration, length of stay, postoperative ileus, anastomotic leak, venous thromboembolism, wound infection, cardiac complications and pulmonary complications. On multivariable analysis, robotic surgery was protective for unplanned conversion, while male sex, malignancy, Crohn disease and diverticular disease were all associated with open conversion. Conclusion Robotic colorectal surgery has comparable 30-day perioperative morbidity to laparoscopic surgery and may decrease the rate of intraoperative conversion in select patients. PMID:27240135

    Nickel oxide in the form of nanoparticles (NiO NPs) is extensively used in different industrial branches. In a test on adult zebrafish, the acute toxicity of NiO NPs was shown to be low, however longlasting contact with this compound can lead to its accumulation in the tissues and to increased toxicity. In this work we determined the 30-day toxicity of NiO NPs using a static test for zebrafish Danio rerio. We found the 30-day LC50 value to be 45.0 mg/L, LC100 (minimum concentration causing 100% mortality) was 100.0 mg/L, and LC0 (maximum concentration causing no mortality) was 6.25 mg/L for adult individuals of zebrafish. Considering a broad use of Ni in the industry, NiO NPs chronic toxicity may have a negative impact on the population of aquatic organisms and on food web dynamics in aquatic systems. PMID:26038672

    Objective To determine the relationship between preoperative hypoalbuminemia and the development of complications after gynecological cancer surgery, as well as postoperative bowel function and hospital stay. Methods The medical records of 533 patients with gynecological cancer surgery at Konkuk University Hospital between 2005 and 2013 were reviewed. Serum albumin level <3.5 g/dL was defined as hypoalbuminemia. All perioperative complications within 30-days after surgery, time to resumption of normal diet and length of postoperative hospital stay, were analyzed. Regression models were used to assess predictors of postoperative morbidity. Results The median age was 49 years (range, 13 to 85 years). Eighty patients (15%) had hypoalbuminemia. Hypoalbuminemic patients had significantly higher consumption of alcohol >2 standard drinks per day, lower American Society of Anesthesiologist score, higher frequency of ascites, and more advanced stage compared with non-hypoalbuminemic patients. Overall complication rate within 30-days after surgery was 20.3% (108 out of 533). Hypoalbuminemic patients were more likely to develop postoperative complications compared to non-hypoalbuminemic patients (34.3% vs. 17.8%, P=0.022), and had significantly longer median time to resumption of normal diet (3.3 [1-6] vs. 2.8 [0-15] days, P=0.005) and length of postoperative hospital stay (0 [7-50] vs. 9 [1-97] days, P=0.014). In multivariate analysis, age >50 (odds ratio [OR], 2.478; 95% confidence interval [CI], 1.310 to 4.686; P=0.005), operation time (OR, 1.006; 95% CI, 1.002 to 1.009; P=0.006), and hypoalbuminemia (OR, 2.367; 95% CI, 1.021 to 5.487; P=0.044) were the significant risk factor for postoperative complications. Conclusion Preoperative hypoalbuminemia in patients with elective surgery for gynecologic malignancy is an independent predictor of 30-days postoperative complications. Identification of this subset and preoperative optimization of nutritional status may improve

    Objective: 30 day re-admission of patients following TKJR is estimated between 0.9-9.9%. It’s a cause of significant cost to the healthcare system and marks significant patient morbidity. Aim: The aim of this study is to describe the causes and incidence of patient re-admission to hospital within 30 days of a primary total knee joint replacement between 2009-2015 in a single centre. Methods: In a retrospective cohort study, computerized records were used to evaluated the causes and incidence of patient re-admission within 30 days of discharge following primary TKJR. Results: The total 30 day Re-admission rate was 5.0%. Medical causes for re-admission accounted for 29% of re-admissions. 34% were attributed to non-specific pain/swelling. Infection was attributed to 26%. 29% of patients presented with wound problems, either infective or non-infective. The total incidence of re-operation at 30 days was 0.77%. Conclusions: Our rate of re-admission is consistent with previous studies in the literature. Many patients were found to have no specific cause for re-admission. This suggests it may be possible to further reduce re-admission rates with improved patient education and management of common post-operative symptoms such as pain and swelling. Infection remains a common complication; fortunately the majority superficial infections are successfully treated with antibiotics and few requiring a washout operation. Medical complications account for almost a third showing the importance of good management of patient medical co-morbidities and risk factors.

    Background Preoperative B-type natriuretic peptide (BNP) is known to predict adverse outcomes after cardiac surgery. The value of postoperative BNP for predicting adverse outcomes is less well delineated. The authors hypothesized that peak postoperative plasma BNP (measured postoperative days 1–5) predicts hospital length of stay (HLOS) and mortality in patients undergoing primary coronary artery bypass grafting, even after adjusting for preoperative BNP and perioperative clinical risk factors. Methods This study is a prospective longitudinal study of 1,183 patients undergoing primary coronary artery bypass grafting surgery. Mortality was defined as all-cause death within 5 yr after surgery. Cox proportional hazards analyses were conducted to separately evaluate the associations between peak postoperative BNP and HLOS and mortality. Multivariable adjustments were made for patient demographics, preoperative BNP concentration, and clinical risk factors. BNP measurements were log10 transformed before analysis. Results One hundred fifteen deaths (9.7%) occurred in the cohort (mean follow-up = 4.3 yr, range = 2.38–5.0 yr). After multivariable adjustment for preoperative BNP and clinical covariates, peak postoperative BNP predicted HLOS (hazard ratio [HR] = 1.28, 95% CI = 1.002–1.64, P = 0.049) but not mortality (HR = 1.62, CI = 0.71–3.68, P = 0.25), whereas preoperative BNP independently predicted HLOS (HR = 1.09, CI = 1.01–1.18, P = 0.03) and approached being an independent predictor of mortality (HR = 1.36, CI = 0.96–1.94, P = 0.08). When preoperative and peak postoperative BNP were separately adjusted for within the clinical multivariable models, each independently predicted HLOS (preoperative BNP HR = 1.13, CI = 1.05–1.21, P = 0.0007; peak postoperative BNP HR = 1.44, CI = 1.15–1.81, P = 0.001) and mortality (preoperative BNP HR = 1.50, CI = 1.09–2.07, P = 0.01; peak postoperative BNP HR = 2.29, CI = 1.11–4.73, P = 0.02).

    Background Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection. Methods All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes. Results We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16). Conclusion Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy. PMID:27017165

    We sought to determine the accuracy of the Model for End-Stage Liver Disease and the Mayo Clinic Postoperative Mortality Risk in Patients with Cirrhosis Calculator in patients with ascites who underwent colorectal surgery. The National Surgical Quality Improvement Program database was queried for patients with ascites who underwent a major colorectal operation. Predicted 90-day mortality rate based on the Model for End-Stage Liver Disease and 30-day mortality based on the Mayo Clinic Postoperative Mortality Risk in Patients with Cirrhosis Calculator were compared with observed 30-day mortality. The cohort contained 3137 patients with ascites who underwent a colorectal operation. The Model for End-Stage Liver Disease predicted that 252 (8 %) of patients with ascites undergoing colorectal operations would die within 90 days postoperatively, yet we observed 821 deaths (26 % mortality) within 30 days after surgery (p < 0.001). The Mayo Clinic Postoperative Mortality Risk in Patients with Cirrhosis Calculator predicted that 491 (16.6 % mortality) of patients with ascites undergoing colorectal operations would die within 30 days postoperatively, yet we observed 707 (23.9 % mortality) at 30 days (p < 0.01). We concluded that the current risk prediction models significantly under predict mortality in patients with ascites who underwent colorectal surgery. PMID:27216407

    The proportion of elderly patients who undergo surgery has rapidly increased; however, clinical indicators predicting outcomes are limited. Our aim was to evaluate the significance of comprehensive geriatric assessment (CGA) in elderly patients undergoing elective surgery. We studied 141 consecutive elderly patients (age: 78.0±6.5 years old, male: 41.1%) who were referred to our geriatric department for surgical risk evaluation. CGA was performed to evaluate physical health, functional status, psychological health, and social support. The primary composite outcome of this study was in-hospital death or post-discharge institutionalization. In-hospital adverse events, such as delirium, pressure ulcers, pneumonia, and urinary tract infections, were also evaluated. The associations between CGA and in-hospital adverse events, in-hospital death, and post-discharge institutionalization were investigated. There were 32 adverse outcomes (6 in-hospital deaths and 26 post-discharge institutionalizations). Compared with the patients who were discharged to their homes, patients with adverse outcomes were characterized by poor nutritional status and prior strokes. However, there was no significant difference in surgical risk or anesthesia type. The CGA results showed that patients with adverse outcomes were associated with functional dependency and poor nutrition. The cumulative number of impairments in the CGA domain was significantly associated with adverse outcomes, in-hospital events, and prolonged hospital stays. In multiple logistic regression analysis, cumulative impairment in CGA was independently associated with surgical outcomes in elderly patients undergoing elective surgery. Preoperative CGA can identify elderly patients at greater risk for mortality, post-discharge institutionalization, adverse in-hospital events, and prolonged length of hospital stay. PMID:23246499

    Previous studies have demonstrated no significant difference in overall functional outcomes of patients discharged to a sub acute setting versus home with health services after total joint arthroplasty. These findings coupled with pressure to reduce health care costs and the implementation of a prospective payment system under Medicare have supported the use of home rehabilitation services and the trend towards earlier discharge after hospitalization. While the overall functional outcome of patients discharged to various settings has been studied, there is a relative dearth of investigation comparing postoperative complications and readmission rates between various discharge dispositions. Our study demonstrated patients discharged home with health services had a significantly lower 30 day readmission rate compared to those discharged to inpatient rehab facilities. Patients discharged to rehab facilities have a higher incidence of comorbidity and this association could be responsible for their higher rate of readmission. PMID:24183369

    We investigated the effect of preoperative patient demographics and operative factors on mortality in the 30day postoperative period after spine surgery. Postoperative mortality from surgical interventions has significantly decreased with progressive improvement in surgical techniques and patient selection. Well-studied preoperative risk factors include age, obesity, emphysema, clotting disorders, renal failure, and cardiovascular disease. However, the prognostic implications of such risk factors after spine surgery specifically remain unknown. The medical records of all consecutive patients undergoing spine surgery from 2008-2010 at our institution were reviewed. Patient demographics, comorbidities, indication for operation, surgical details, postoperative complications, and mortalities were collected. The association between preoperative demographics or surgical details and postoperative mortality was assessed via logistic regression analysis. All 1344 consecutive patients (1153 elective, 191 emergency) met inclusion criteria for the study; 19 (1.4%) patients died in the 30days following surgery. Multivariable logistic regression found several predictive factors of mortality for all spine surgery patients: operation in the cervical area (odds ratio [OR]: 7.279, 95% confidence interval [CI]: 1.37-42.83, p=0.02), postoperative sepsis (OR: 5.75, 95% CI: 1.16-26.38, p=0.03), operation for neoplastic (OR: 7.68, 95% CI: 1.53-42.71, p=0.01) or traumatic (OR: 13.76, 95% CI: 2.40-88.68, p=0.03) etiology, and age as defined as a continuous variable (OR: 1.05, 95% CI: 1.01-1.10, p=0.03). This study demonstrates predictive factors to help identify and evaluate patients who are at higher risk for mortality from spinal surgery, and potentially devise methods to reduce this risk.

    Abstract The purpose of this study was to determine the risk of surgical mortality and morbidity in patients with diabetes mellitus (DM) undergoing a gastrectomy for gastric cancer (GC). Using the Taiwan National Health Insurance Research Database, we identified 6284 patients who underwent gastrectomy for GC from 1999 to 2010. In addition, we created a non-DM control cohort consisting of 6268 patients who received gastrectomy during the same period. Compared with the non-DM cohort, the DM cohort exhibited a higher prevalence of preoperative coexisting medical conditions, namely hypertension, hyperlipidemia, coronary artery disease, chronic kidney disease, chronic pulmonary disease, stroke, and cirrhosis. The odds ratio (OR) of 30-day postoperative mortality after gastrectomy in the DM cohort was 1.04 (95% confidence interval 0.78–1.40) after we adjusted for covariates. The DM cohort did not exhibit a significantly higher risk of 30-day postoperative morbidities. Further analysis revealed that only patients with a history of a DM-related coma exhibited a higher risk of 30-day postoperative mortality (adjusted OR 2.46, 95% confidence interval 1.10 − 5.54). Moreover, the risk of 90-day postoperative mortality was significantly higher in patients with DM-related eye involvement, coma, peripheral circulatory disease, and renal manifestations, in comparison with the non-DM cohort. The risk of 90-day mortality after gastrectomy for GC is higher in patients with DM-related manifestations than those without DM. PMID:26376386

    BACKGROUND: Surgery for hip fractures can be done under general or neuraxial anesthesia. This study aimed to compare these two methods concerning their postoperative complications, duration of operation, hospitalization and the mortality rate within a period of one month after surgery. METHODS: 400 patients aged more than 30 years old and scheduled for elective operative fixation of fractured hip, randomly enrolled in two equal groups of general (GA) and neuraxial (NA) anesthesia. Hemoglobin level was measured before and 6 hours, 2, 3 and 5 days after the surgery. The intra and postoperative blood loss, duration of surgery, the severity of pain at the time of discharge from recovery and at the 2nd, 3rd and 5th postoperative days were recorded. Statistical analysis was performed using SPSS version 12.0 by Mann-Whitney, chi-square, and t tests. P < 0.05 was considered significant. RESULTS: Both groups were similar regarding age, weight, and gender ratio. There was no significant difference in baseline hemoglobin, duration of surgery, length of hospitalization before surgery and the type of surgery. The mean of intraoperative blood loss and visual analogue score (VAS) in recovery and at the 3rd postoperative day, and also the length of hospitalization after surgery were significantly less in neuraxial anesthesia group. Both groups showed a significant decrease in hemoglobin values on the 2nd and 3rd postoperative days comparing to the baseline (p < 0.001). CONCLUSIONS: The morbidity and mortality rates of patients undergoing hip surgery were similar in both methods of anesthesia, but postoperative pain, blood loss, and duration of hospitalization were more in patients undergoing general anesthesia.

    Introduction. Surgical treatment of perforated peptic ulcer (PPU) is a challenge for surgeons in Africa. Aim. To determine risk factors of postoperative complications or mortality among black Ivoirian patients with PPU. Methods. All 161 patients (median age = 34 years, 90.7 male) operated on for PPU in the visceral and general surgery unit were enrolled in a retrospective cohort study. Variables were studied with Kaplan Meier and Cox proportional hazard models. Results. Among 161 patients operated on for PPU, 36 (27.5%) experienced complications and 31 (19.3%) died. Follow-up results were the incidence of complications and mortality of 6.4 (95% CI: 4.9–8.0) per 100 person-days and 3.0 (95% CI: 1.9–4.0) per 100 person-days for incidence of mortality. In multivariate analysis, risk factors of postoperative complications or mortality were comorbidities (HR = 2.1, P = 0.03), tachycardia (pulse rate > 100/minutes) (HR = 2.4, P = 0.02), purulent intra-abdominal fluid collection (HR = 2.1, P = 0.04), hyponatremia (median value ≤ 134 mEq/L) (HR = 2.3, P = 0.01), delayed time of hospital admission > 72 hours (HR = 2.6, P < 0.0001), and delayed time of surgical intervention between 24 and 48 hours (HR = 3.8, P < 0.0001). Conclusion. The delayed hospital admission or surgical intervention and hyponatremia may be considered as additional risk of postoperative complications or mortality in Black African patients with PPU.

    OBJECT Hospital readmission is a common but controversial quality measure increasingly used to influence hospital compensation in the US. The objective of this study was to evaluate the causes for 30-day hospital readmission following aneurysmal subarachnoid hemorrhage (SAH) to determine the appropriateness of this performance metric and to identify potential avenues for improved patient care. METHODS The authors retrospectively reviewed the medical records of all patients who received surgical orendovas-cular treatment for aneurysmal SAH at Barnes-Jewish Hospital between 2003 and 2013. Two senior faculty identified by consensus the primary medical/surgical diagnosis associated with readmission as well as the underlying causes of rehospitalization. RESULTS Among 778 patients treated for aneurysmal SAH, 89 experienced a total of 97 readmission events, yielding a readmission rate of 11.4%. The median time from discharge to readmission was 9 days (interquartile range 3-17.5 days). Actual hydrocephalus or potential concern for hydrocephalus (e.g., headache) was the most frequent diagnosis (26/97, 26.8%), followed by infections (e.g., wound infection [5/97, 5.2%], urinary tract infection [3/97, 3.1%], and pneumonia [3/97, 3.1%]) and thromboembolic events (8/97, 8.2%). In most cases (75/97, 77.3%), we did not identify any treatment lapses contributing to readmission. The most common underlying causes for readmission were unavoidable development of SAH-related pathology (e.g., hydrocephalus; 36/97, 37.1%) and complications related to neurological impairment and immobility (e.g., thromboembolic event despite high-dose chemoprophylaxis; 21/97, 21.6%). The authors determined that 22/97 (22.7%) of the readmissions were likely preventable with alternative management. In these cases, insufficient outpatient medical care (for example, for hyponatremia; 16/97, 16.5%) was the most common shortcoming. CONCLUSIONS Most readmissions after aneurysmal SAH relate to late consequences of

    Background Heart failure (HF) is the leading cause for hospital readmission. Hospice care may help palliate HF symptoms but its association with 30-day all-cause readmission remains unknown. Methods and Results Of the 8032 Medicare beneficiaries hospitalized for HF in 106 Alabama hospitals (1998–2001), 182 (2%) received discharge hospice referrals. Of the 7850 patients not receiving hospice referrals, 1608 (20%) died within 6 months post-discharge (the hospice-eligible group). Propensity scores for hospice referral were estimated for each of the 1790 (182+1608) patients and were used to match 179 hospice-referral patients with 179 hospice-eligible patients who were balanced on 28 baseline characteristics (mean age, 79 years, 58% women, 18% African American). Overall, 22% (1742/8032) died in 6 months, of whom 8% (134/1742) received hospice referrals. Among the 358 matched patients, 30-day all-cause readmission occurred in 5% and 41% of hospice-referral and hospice-eligible patients, respectively (hazard ratio {HR} associated with hospice referral, 0.12; 95% confidence interval {CI}, 0.06–0.24). HRs (95% CIs) for 30-day all-cause readmission associated with hospice referral among the 126 patients who died and 232 patients who survived 30-day post-discharge were 0.03 (0.04–0.21) and 0.17 (0.08–0.36), respectively. Although 30-day mortality was higher in the hospice referral group (43% vs. 27%), it was similar at 90 days (64% vs. 67% among hospice-eligible patients). Conclusions A discharge hospice referral was associated with lower 30-day all-cause readmission among hospitalized HF patients. However, most HF patients who died within 6 months of hospital discharge did not receive a discharge hospice referral. PMID:26019151

    Purpose To analyze rate, risk factors, and costs associated with 30-day readmission after ovarian cancer surgery. Patients and Methods The SEER-Medicare linked database (1992 to 2010) was used to evaluate readmission rates within 30 days of index surgery in patients with stage IIIC/IV ovarian, primary peritoneal, or fallopian tube cancer. Multivariable logistic regression was used to identify factors associated with readmission. Results Of 5,152 eligible patients, 1,003 (19.5%) were readmitted within 30 days of discharge. Mean patient age was 75 years. Diagnoses associated with readmission included infection (34.7%), dehydration (34.3%), ileus/obstruction (26.2%), metabolic/electrolyte derangements (23.1%), and anemia (12.3%). In multivariable analysis, year of discharge was significantly associated with 30-day readmission (1996 to 2000: odds ratio [OR], 1.32; 95% CI, 1.01 to 1.71; 2001 to 2005: OR, 1.58; 95% CI, 1.24 to 2.0; 2006 to 2010: OR, 1.73; 95% CI, 1.35 to 2.21; referent years 1992 to 1995), as were length of index hospital stay more than 8 days (OR, 1.39; 95% CI, 1.18 to 1.64) and discharge to a skilled nursing facility (OR, 1.3; 95% CI, 1.04 to 1.63). Patients readmitted within 30 days had a significantly greater 1-year mortality rate compared with patients not readmitted (41.1% v 25.1%, respectively; P < .001). The median cost of readmission hospital stay was $9,220 in year 2010 dollars, with a total cost of $9.3 million over the study period. Conclusion Early readmission after surgery for ovarian cancer is common. There is a significant association between 30-day readmission and 1-year mortality. These findings may catalyze development of targeted interventions to decrease early readmission, improve patient outcomes, and control health care costs. PMID:25385738

    Introduction Inpatient hospital readmissions have become a focus for healthcare reform and cost-containment efforts. Initiatives targeting unanticipated readmissions have included care coordination for specific high readmission diseases and patients and health coaching during the post-discharge transition period. However, little research has focused on emergency department (ED) visits following an inpatient admission. The objective of this study was to assess 30-day ED utilization and all-cause readmissions following a hospital admission. Methods This was a retrospective study using inpatient and ED utilization data from two hospitals with a shared patient population in 2011. We assessed the 30-day ED visit rate and 30-day readmission rate and compared patient characteristics among individuals with 30-day inpatient readmissions, 30-day ED discharges, and no 30-day visits. Results There were 13,449 patients who met the criteria of an index visit. Overall, 2,453 (18.2%) patients had an ED visit within 30 days of an inpatient stay. However, only 55.6% (n=1,363) of these patients were admitted at one of these 30-day visits, resulting in a 30-day all-cause readmission rate of 10.1%. Conclusion Approximately one in five patients presented to the ED within 30 days of an inpatient hospitalization and over half of these patients were readmitted. Readmission measures that incorporate ED visits following an inpatient stay might better inform interventions to reduce avoidable readmissions. PMID:26759647

    Background: Recent research has shown that most of the excess risk of death following breast and colorectal cancer in England compared with Norway and Sweden occurs in older age groups during the first year, and especially in the first month of follow-up. The aim of this study was to explore the characteristics of patients dying within 30 days of being diagnosed with one of these cancers in Scotland during 2003–2007. Methods: Anonymised cancer registry records linked to hospital discharge and death records were extracted. The study population was divided into patients who died within 30 days of diagnosis (cases) and those who survived beyond this threshold (controls). Differences in patient-, tumour-, and health service-related characteristics were assessed using the χ2-test and logistic regression. Results: Patients dying within 30 days were more likely to be elderly and to have experienced emergency admission to non-surgical specialities. Their tumours were less likely to have been verified microscopically, but they appeared more likely to be of high grade and advanced in stage. A substantial number of patients died from causes other than their cancer. Conclusion: These results suggest that early mortality after a diagnosis of breast or colorectal cancer may be partly due to comorbidity and lifestyle factors, as well as due to more advanced disease. Further research is required to determine the precise explanation for these findings and, in particular, if any potentially avoidable factors such as delays in presentation, referral, or diagnosis exist.

    Intracerebral hemorrhage is the deadliest, most disabling and least treatable form of stroke despite progression in medical science. The aim of the study was to analyze the frequency, risk factors, localization and 30-day prognosis in patients with intracerebral hemorrhage. We analyzed 352 patients with intracerebral hemorrhage (ICH) hospitalized at the Department of Neurology Tuzla during a three-year follow up. The following data were collected for all patients in a computerized database: age, sex, risk factors (hypertension, heart diseases, diabetes and smoking) and CT findings. Stroke severity was estimated with Scandinavian Stroke Scale, ICH topography was specified by CT, and outcome at 1st month after onset included information on vital status and disability (modified Rankin Scale, mRS). The most frequent risk factors were hypertension (84%), heart diseases (31%), cigarette smoking (28%) and diabetes mellitus (14%). The most frequent localization of ICH was multilobar (38%), internal capsule/basal ganglia region (36%) and lobar (17%). Within first month died 147 patients (42%). The highest mortality rate was in patients with brain stem (83%) and multilobar hemorrhage (64%). Factors independently associated with mortality were age (odds ratio 1,05 (95% confidence interval 1,02 to 1,08); p=0,001), stroke severity (OR 0,93 (0,92 to 0,95); p<0,0001), multilobar hemorrhage (OR 5,4 (3,0 to 9,6); p<0,0001) and intraventricular hemorrhage (OR 3,9 (2,2 to 7,1); p<0,0001). Favorable outcome at first month (mRS < or = 2) had 45% of the surviving patients with ICH. The best outcome was for the patients with cerebellar hemorrhage (63%), while only 40% of the patients with hemorrhage in internal capsule/basal ganglia region had Rankin scale 2 or less. Hypertension is the most frequent risk factor in patients with ICH. ICHs are mainly localized in lobar and internal capsule/basal ganglia regions. Independent predictors of mortality following ICH are age, hypertension

    2012-01-01

    Background: There are limited national population-based epidemiological data on acute myocardial infarction (AMI) in England, making the current burden of disease, and clinical prognosis, difficult to quantify. The aim of this study was to provide national estimates of incidence and 30-day case fatality rate (CFR) for first and recurrent AMI in England. Methods: Population-based study using person-linked routine hospital and mortality data on 79 896 individuals of any age, who were admitted to hospital for AMI or who died suddenly from AMI in 2010. Results: Of 82 252 AMI events in 2010, 83% were first. Age-standardized incidence of first AMI per 100 000 population was 130 (95% CI 129–131) in men and 55.9 (95% CI 55.3–56.6) in women. Age-standardized 30-day overall CFRs including sudden AMI deaths for men and women, respectively, were 32.4% (95% CI 32.0–32.9) and 30.3% (95% CI 29.8–30.9) for first AMI and 29.7% (95% CI 28.7–30.7) and 26.7% (95% CI 25.5–27.9) for recurrent AMI. Age-standardized hospitalized 30-day CFR was 12.0% (95% CI 11.6–12.3) for men and 12.3% (95% CI 11.9–12.7) for women. Conclusions: While the majority of AMIs are not fatal, of those that are, two-thirds occur as sudden AMI deaths. About one in six of all AMIs are recurrent events. These findings reinforce the importance of primary and secondary prevention in reducing AMI morbidity and mortality. PMID:22241758

    Summary Objective The objective of this study was to compare the short term outcomes of robotic with conventional on pump coronary artery bypass grafting (CABG). Methods The study population included 2091 consecutive patients who underwent either conventional or robotic CABG from January 2007 to March 2012. Pre-operative, intra-operative and 30-day post-operative variables were collected for each group. In order to compare the incidence of rapid recovery between conventional and robotic CABG, the surrogate variables of early discharge and discharge to home (versus rehabilitation or acute care facility) were evaluated. A multivariate logistic regression analysis was utilized. Results One hundred and fifty robotic and 1,619 conventional CABG cases were analyzed. Multivariate logistic regression analysis demonstrated that robotic surgery was a strong predictor of lower 30-day complications (OR = 0.24, p=0.005), short length of stay (OR 3.31, p < 0.001), and decreased need for an acute care facility (OR 0.55, p = 0.032). In the presence of complications (NY State Complication Composite), the robotic technique was not associated with a change in discharge status. Conclusions In this retrospective review robotic CABG was associated with a lower 30-day complication rate, a shorter length of stay and a lower incidence of acute care facility discharge than conventional on pump CABG. It may suggest a more rapid recovery to pre-operative status after robotic surgery: however, only a randomized prospective study could confirm the advantages of a robotic approach PMID:25238421

    Introduction Left atrioventricular valve regurgitation is the most concerning residual lesion after surgical correction of atrioventricular septal defect. Objective To determine factors associated with moderate or greater left atrioventricular valve regurgitation within 30 days of surgical repair of incomplete atrioventricular septal defect. Methods We assessed the results of 51 consecutive patients 14 years-old and younger presenting with incomplete atrioventricular septal defect that were operated on at our practice between 2002 and 2010. The following variables were considered: age, weight, absence of Down syndrome, grade of preoperative left atrioventricular valve regurgitation, abnormalities on the left atrioventricular valve and the use of annuloplasty. The median age was 4.1 years; the median weight was 13.4 Kg; 37.2% had Down syndrome. At the time of preoperative evaluation, there were 23 cases with moderate or greater left atrioventricular valve regurgitation (45.1%). Abnormalities on the left atrioventricular valve were found in 17.6%; annuloplasty was performed in 21.6%. Results At the time of postoperative evaluation, there were 12 cases with moderate or greater left atrioventricular valve regurgitation (23.5%). The variation between pre- and postoperative grades of left atrioventricular valve regurgitation of patients with atrioventricular valve malformation did not reach significance (P=0.26), unlike patients without such abnormalities (P=0.016). During univariate analysis, only absence of Down syndrome was statistically significant (P=0.02). However, after a multivariate analysis, none of the factors reached significance. Conclusion None of the factors studied was determinant of a moderate or greater left atrioventricular valve regurgitation within the first 30 days of repair of incomplete atrioventricular septal defect in the sample. Patients without abnormalities on the left atrioventricular valve benefit more of the operation. PMID:26107451

    A retrospective analysis of operative mortality in the cancer surgery department of the Fondation Bergonié between 1975 and 1984 allowed priority objectives to be defined requiring maximum efforts of the treating team. During this decade, 18,582 patients underwent surgery; 15,794 "first hand" operations were for cases not previously treated. Amongst the latter, 102 died within 90 days of surgery, 45 due to multifocal or apparently isolated pulmonary infection and 57 without any known infectious context. Separating patients into two groups: periods 1975-1979 and 1980-1984, demonstrated a notable decrease in postoperative mortality from 68 to 34. This improvement was due mainly to a reduction in deaths from infection (from 37 to 8 patients in the period 1980-1984). This marked improvement was probably the result of various combined causes: Mastery of parenteral nutrition enabling patients to be operated upon in better condition, or to tolerate possible complications better; Use of routine antibiotic therapy before surgery to digestive tube or ORL regions. These encouraging result suggest the need for enlargement of indications for routine prophylactic antibiotic therapy. PMID:3584279

  20. Effect of feeding in 30-day bioaccumulation assays using Hyalella azteca in fluoranthene-dosed sediment

    1995-12-31

    Current protocols for conducting freshwater sediment bioaccumulation tests require that food be added to exposures. To determine effects of adding food, 30-day bioaccumulation assays were conducted with H. azteca exposed to sediment dosed with four concentrations (0.05 to 1,267 nmol/g dry weight) of fluoranthene. Accumulation was significantly greater in fed versus non-fed animals at all dose levels after 96 and 240 hours of exposure and continued to be greater after 30 days in the low dose levels. At sediment concentrations above 634 nmol/g dw, survival of unfed animals dropped to 34% after 30 days, However, after 30 days, reproduction was observed in fed animals exposed to sediment concentrations > 16 times the expected LC50 calculated for fluoranthene in sediment. These data raise questions concerning the interpretation of standard toxicity and bioaccumulation tests when food is routinely added.

    According to previous investigations, CD14 is suggested to play a pivotal role in initiating and perpetuating the pro-inflammatory response during sepsis. A functional polymorphism within the CD14 gene, rs2569190, has been shown to impact the pro-inflammatory response upon stimulation with lipopolysaccharide, a central mediator of inflammation in sepsis. In this study, we hypothesized that the strong pro-inflammatory response induced by the TT genotype of CD14 rs2569190 may have a beneficial effect on survival (30-day) in patients with sepsis. A total of 417 adult patients with sepsis (and of western European descent) were enrolled into this observational study. Blood samples were collected for rs2569190 genotyping. Patients were followed over the course of their stay in the ICU, and the 30-day mortality risk was recorded as the primary outcome parameter. Sepsis-related organ failure assessment (SOFA) scores were quantified at sepsis onset and throughout the observational period to monitor organ failure as a secondary variable. Moreover, organ support-free days were evaluated as a secondary outcome parameter. TT-homozygous patients were compared to C-allele carriers. Kaplan-Meier survival analysis revealed a higher 30-day mortality risk among C-allele carriers compared with T homozygotes (p = 0.0261). To exclude the effect of potential confounders (age, gender, BMI and type of infection) and covariates that varied at baseline with a p-value < 0.2 (e.g., comorbidities), we performed multivariate Cox regression analysis to examine the survival time. The CD14 rs2569190 C allele remained a significant covariate for the 30-day mortality risk in the multivariate analysis (hazard ratio, 2.11; 95% CI, 1.08-4.12; p = 0.0282). The 30-day mortality rate among C allele carriers was 23%, whereas the T homozygotes had a mortality rate of 13%. Additionally, an analysis of organ-specific SOFA scores revealed a significantly higher SOFA-Central nervous system score among patients

    Abstract Thirty-day readmission rates, a widely utilized quality metric, are high among HIV-infected individuals. However, it is unknown how many 30-day readmissions are preventable, especially in HIV patients, who have been excluded from prior potentially preventable readmission analyses. We used electronic medical records to identify all readmissions within 30 days of discharge among HIV patients hospitalized at a large urban safety net hospital in 2011. Two independent reviewers assessed whether readmissions were potentially preventable using both published criteria and detailed chart review, how readmissions might have been prevented, and the phase of care deemed suboptimal (inpatient care, discharge planning, post-discharge). Of 1137 index admissions, 213 (19%) resulted in 30-day readmissions. These admissions occurred among 930 unique HIV patients, with 130 individuals (14%) experiencing 30-day readmissions. Of these 130, about half were determined to be potentially preventable using published criteria (53%) or implicit chart review (48%). Not taking antiretroviral therapy (ART) greatly increased the odds of a preventable readmission (OR 5.9, CI:2.4–14.8). Most of the preventable causes of readmission were attributed to suboptimal care during the index hospitalization. Half of 30-day readmission in HIV patients are potentially preventable. Increased focus on early ART initiation, adherence counseling, management of chronic conditions, and appropriate timing of discharge may help reduce readmissions in this vulnerable population.

    Different countries have their own police reporting time standards for counting the number of fatalities in reported crashes. A rapid estimation method (such as adjustment factor) for the comparison is important. The data-linkage technique was used to combine police-reported crash data and vital registration data, in order to generate 30-day fatality adjustment factors for various reporting time standards, which could also shed light on the fatal injury trend over time. The major findings were as follows. Firstly, a conservative 30-day fatality adjustment factor for the first day (or 24 h) would be 1.54 (or 1.35) in an area with a large motorcycle population, like Taiwan. This produced 20-40% higher 30-day fatalities than UK Transport Research Laboratory predicted, and 15-25% higher fatalities than those in Europe/Japan. Secondly, after excluding motorcycle impacts, the Taiwanese factors suggested 8-14% higher fatalities within 30 days than those in Europe/Japan. Third, motorcycle fatalities influenced the overall 30-day fatality trend within 3 days. In the future, both the police under-reporting problem and the motorcycle/overall fatal injury pattern within 3 days after crashing in developing countries like Taiwan merit further investigation.

    Myelinated fibers and myelin-forming cells in the spinal cord at the L3-L5 level were studied in C57BL/6N mice that had spent 30 days in space. Signs of destruction of myelin in different areas of white matter, reduction of the thickness of myelin sheath and axon diameter, decreased number of myelin-forming cells were detected in "flight" mice. The stay of mice in space during 30 days had a negative impact on the structure of myelinated fibers and caused reduced expression of the markers myelin-forming cells. These findings can complement the pathogenetic picture of the development of hypogravity motor syndrome. PMID:27595822

    Background Few data exist related to the impact of roflumilast on health care utilization. This retrospective study estimated 30-day hospital readmission rates between patients who did and did not use roflumilast among those with COPD hospitalizations. Methods Data were from MarketScan, a large US commercial health insurance claims database. Patients aged ≥40 years with at least one hospitalization for COPD between 2010 and 2011 were included. The roflumilast group included patients who used roflumilast within 14 days after the first hospitalization (index), while the comparison group (non-roflumilast) included patients who did not use roflumilast during the study period. Continuous enrollment for at least 6 months before and 30 days after the index date was required. The 30-day hospitalization rate was calculated after the index hospitalization. Conditional logistic regression with propensity score 1:3 matching was employed to assess the difference in 30-day hospital readmission rates between the roflumilast and non-roflumilast groups, adjusting for baseline characteristics, comorbidity, health care utilization, and COPD medication use within 14 days after the index date. Results A total of 15,755 COPD patients met the selection criteria, ie, 366 (2.3%) in the roflumilast group and 15,389 (97.7%) in the non-roflumilast group. The mean (± standard deviation) age was 71±12.5 years and 52% were female. After propensity score matching, all-cause 30-day hospitalization rates were 6.9% and 11.1% in the roflumilast and non-roflumilast groups, respectively. COPD-related 30-day hospitalization rates were 6.3% and 9.2% in the roflumilast and non-roflumilast groups, respectively. Conditional logistic regression identified a significantly lower likelihood of all-cause 30-day readmission (odds ratio 0.59, 95% confidence interval 0.37–0.93, P=0.023) for roflumilast patients relative to non-roflumilast patients. Conclusion This study showed, in a real-world setting, that

    Congestive heart failure (CHF) accounts for more health care costs than any other diagnosis. Readmissions contribute to this expenditure. The authors evaluated the relationship between adherence to performance metrics and 30-day readmissions. This was a retrospective study of 6063 patients with CHF between 2001 and 2008. Data were collected for 30-day readmissions and compliance with CHF performance measures at discharge. Rates of readmission for CHF increased from 16.8% in 2002 to 24.8% in 2008. Adherence to performance measures increased concurrently from 95.8% to 99.9%. Except for left ventricular function (LVF) assessment, the 30-day readmission rate was not associated with adherence to performance measures. Readmitted patients had twice the odds of not having their LVF assessed (odds ratio = 2.0; P < .00005; 95% confidence interval = 1.45-2.63). CHF performance measures, except for the LVF assessment, have little relationship to 30-day readmissions. Further studies are needed to identify performance measures that correlate with quality of care. PMID:23110998

    Bailey, Stacy Cooper; Fang, Gang; Annis, Izabela E; O'Conor, Rachel; Paasche-Orlow, Michael K; Wolf, Michael S

    2015-01-01

    Objective To assess the validity of a predictive model of health literacy, and to examine the relationship between derived health literacy estimates and 30-day hospital readmissions for acute myocardial infarction (AMI). Design Retrospective cohort study. Setting and participants A National Institute of Aging (NIA) study cohort of 696 adult, English-speaking primary care patients, aged 55–74 years, was used to assess the validity of derived health literacy estimates. Claims from 7733 Medicare beneficiaries hospitalised for AMI in 2008 in North Carolina and Illinois were used to investigate the association between health literacy estimates and 30-day hospital readmissions. Measures The NIA cohort was administered 3 common health literacy assessments (Newest Vital Sign, Test of Functional Health Literacy in Adults, and Rapid Estimate of Adult Literacy in Medicine). Health literacy estimates at the census block group level were derived via a predictive model. 30-day readmissions were measured from Medicare claims data using a validated algorithm. Results Fair agreement was found between derived estimates and in-person literacy assessments (Pearson Correlation coefficients: 0.38–0.51; κ scores: 0.38–0.40). Medicare enrollees with above basic literacy according to derived health literacy estimates had an 18% lower risk of a 30-day readmission (RR=0.82, 95% CI 0.73 to 0.92) and 21% lower incidence rate of 30-day readmission (IRR=0.79, 95% CI 0.68 to 0.87) than patients with basic or below basic literacy. After adjusting for demographic and clinical characteristics, the risk of 30-day readmission was 12% lower (p=0.03), and the incidence rate 16% lower (p<0.01) for patients with above basic literacy. Conclusions Health literacy, as measured by a predictive model, was found to be a significant, independent predictor of 30-day readmissions. As a modifiable risk factor with evidence-based solutions, health literacy should be considered in readmission reduction

    2013-01-01

    Objectives We sought to identify risk factors for mortality and morbidity during the Norwood hospitalization in newborn infants with hypoplastic left heart syndrome and other single right ventricle anomalies enrolled in the Single Ventricle Reconstruction trial. Methods Potential predictors for outcome included patient- and procedure-related variables and center volume and surgeon volume. Outcome variables occurring during the Norwood procedure and before hospital discharge or stage II procedure included mortality, end-organ complications, length of ventilation, and hospital length of stay. Univariate and multivariable Cox regression analyses were performed with bootstrapping to estimate reliability for mortality. Results Analysis included 549 subjects prospectively enrolled from 15 centers; 30-day and hospital mortality were 11.5% (63/549) and 16.0% (88/549), respectively. Independent risk factors for both 30-day and hospital mortality included lower birth weight, genetic abnormality, extracorporeal membrane oxygenation (ECMO) and open sternum on the day of the Norwood procedure. In addition, longer duration of deep hypothermic circulatory arrest was a risk factor for 30-day mortality. Shunt type at the end of the Norwood procedure was not a significant risk factor for 30-day or hospital mortality. Independent risk factors for postoperative renal failure (n = 46), sepsis (n = 93), increased length of ventilation, and hospital length of stay among survivors included genetic abnormality, lower center/surgeon volume, open sternum, and post-Norwood operations. Conclusions Innate patient factors, ECMO, open sternum, and lower center/surgeon volume are important risk factors for postoperative mortality and/or morbidity during the Norwood hospitalization.

    Abstract The objective of this study was to determine the 30-day incidence of ischemic stroke following neck dissection compared to matched patients undergoing non-head and neck surgeries. A surgical dissection of the neck is a common procedure performed for many types of cancer. Whether such dissections increase the risk of ischemic stroke is uncertain. A retrospective cohort study using data from linked administrative and registry databases (1995–2012) in the province of Ontario, Canada was performed. Patients were matched 1-to-1 on age, sex, date of surgery, and comorbidities to patients undergoing non-head and neck surgeries. The primary outcome was ischemic stroke assessed in hospitalized patients using validated database codes. A total of 14,837 patients underwent surgical neck dissection. The 30-day incidence of ischemic stroke following the dissection was 0.7%. This incidence decreased in recent years (1.1% in 1995 to 2000; 0.8% in 2001 to 2006; 0.3% in 2007 to 2012; P for trend <0.0001). The 30-day incidence of ischemic stroke in patients undergoing neck dissection is similar to matched patients undergoing thoracic surgery (0.5%, P = 0.26) and colectomy (0.5%, P = 0.1). Factors independently associated with a higher risk of stroke in 30 days following neck dissection surgery were of age ≥75 years (odds ratio (OR) 1.63, 95% confidence interval (CI) 1.05–2.53), and a history of diabetes (OR 1.60, 95% CI 1.02–2.49), hypertension (OR 2.64, 95% CI 1.64–4.25), or prior stroke (OR 4.06, 95% CI 2.29–7.18). Less than 1% of patients undergoing surgical neck dissection will experience an ischemic stroke in the following 30 days. This incidence of stroke is similar to thoracic surgery and colectomy.

    Mulligan, Michael S; Berfield, Kathleen S; Abbaszadeh, Ryan V

    2015-11-01

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. PMID:26515943

  2. Beyond volume: hospital-based healthcare technology as a predictor of mortality for cardiovascular patients in Korea

    2016-01-01

    Abstract To examine whether hospital-based healthcare technology is related to 30-day postoperative mortality rates after adjusting for hospital volume of cardiovascular surgical procedures. This study used the National Health Insurance Service–Cohort Sample Database from 2002 to 2013, which was released by the Korean National Health Insurance Service. A total of 11,109 cardiovascular surgical procedure patients were analyzed. The primary analysis was based on logistic regression models to examine our hypothesis. After adjusting for hospital volume of cardiovascular surgical procedures as well as for all other confounders, the odds ratio (OR) of 30-day mortality in low healthcare technology hospitals was 1.567-times higher (95% confidence interval [CI] = 1.069–2.297) than in those with high healthcare technology. We also found that, overall, cardiovascular surgical patients treated in low healthcare technology hospitals, regardless of the extent of cardiovascular surgical procedures, had the highest 30-day mortality rate. Although the results of our study provide scientific evidence for a hospital volume–mortality relationship in cardiovascular surgical patients, the independent effect of hospital-based healthcare technology is strong, resulting in a lower mortality rate. As hospital characteristics such as clinical pathways and protocols are likely to also play an important role in mortality, further research is required to explore their respective contributions.

    Background Newfoundland and Labrador (NL) has the highest rate of obesity in Canada, prompting the establishment of a bariatric surgery program at the Health Sciences Centre in NL. This retrospective study examined 30-day complication rates in more than 200 consecutive patients who underwent laparoscopic sleeve gastrectomy (LSG) between May 2011 and February 2014. Methods We performed a chart review and collected data on 30-day postoperative complications. Complications were graded and reported using the Clavien–Dindo classification. Grades I and II were defined as minor and grades III and higher were defined as major complications. Results We reviewed the charts of the first 209 patients to undergo LSG. The mean body mass index was 49.2, 81% were women and the average age was 43 years. Comorbidities included hypertension (55.0%), obstructive sleep apnea (46.4%), dyslipidemia (42.1%), diabetes (37.3%), osteoarthritis (36.4%) and cardiovascular disease with previous cardiac stents (5.3%). Furthermore, 38.3% of patients reported psychiatric diagnoses, such as depression and anxiety. The overall 30-day complication rate was 15.3%. The complication rate for minor complications was 13.4% and for major complications was 1.9% (2 leaks, 1 stricture and 1 fistula). Conclusion Our results support the feasibility of safely performing LSG surgery at bariatric centres completing fewer than 125 procedures annually. PMID:27007089

    Total hip replacement causes a short-term increase in the risk of mortality. It is important to quantify this and to identify modifiable risk factors so that the risk of post-operative mortality can be minimised. We performed a systematic review and critical evaluation of the current literature on the topic. We identified 32 studies published over the last 10 years which provide either 30-day or 90-day mortality data. We estimate the pooled incidence of mortality during the first 30 and 90 days following hip replacement to be 0.30% (95% CI 0.22 to 0.38) and 0.65% (95% CI 0.50 to 0.81), respectively. We found strong evidence of a temporal trend towards reducing mortality rates despite increasingly co-morbid patients. The risk factors for early mortality most commonly identified are increasing age, male gender and co-morbid conditions, particularly cardiovascular disease. Cardiovascular complications appear to have overtaken fatal pulmonary emboli as the leading cause of death after hip replacement. Cite this article: Bone Joint Res 2014;3:175–82. PMID:24894596

    Results are presented from a study to determine whether or not short-term variable intensity isotonic and intermittent high-intensity isokinetic short-duration leg exercise is effective for the maintenance of peak O2 (VO2) uptake and muscular strength and endurance, respectively, during 30 days of -6 deg head-down bed rest deconditioning. The results show no significant changes in leg peak torque, leg mean total work, arm total peak torque, or arm mean total work for members of the isotonic, isokinetic, and controls groups. Changes are observed, however, in peak VO2 levels. The results suggest that near-peak variabile intensity, isotonic leg excercise maintains peak VO2 during 30 days of bed rest, while peak intermittent, isokinetic leg excercise protocol does not.

    Objective The Centers for Medicare and Medicaid Services (CMS) implemented a policy in 2012 that penalizes hospitals for ‘excessive’ all-cause hospital readmissions within 30 days after discharge for heart failure (HF), acute myocardial infarction (AMI), and pneumonia. The aim of this study is to investigate the influence of psychiatric comorbidities on 30-day all-cause readmissions for heart failure, acute myocardial infarction, and pneumonia. Methods Longitudinal study from 2009-2011 within 11 Mental Health Research Network (MHRN) affiliated health systems. Data were derived from the HMO Research Network Virtual Data Warehouse. Participants were individuals admitted to the hospital for HF, AMI, and pneumonia. All index inpatient hospitalizations for HF, AMI and pneumonia were captured (n=160,169 patient index admissions). Psychiatric diagnoses were measured for the year prior to admission. All-cause readmissions within 30 days of discharge were the outcome variable. Results Approximately 18% of all individuals with these conditions were readmitted within 30-days. The rate was 5% greater for individuals with a past-year psychiatric comorbidity (21.7%) than for those without (16.5%; p<.001). Depression, anxiety, and dementia were associated with more readmissions for those with index hospitalizations for all three conditions independently and combined (p<.05). Substance use and bipolar disorders were linked with higher readmissions for those with initial HF and pneumonia hospitalizations (p<.05). Readmission rates declined overall from 2009-2011. Conclusions Individuals with HF, AMI, and pneumonia experience high rates of readmission, but psychiatric comorbidities appear to increase that risk. Future readmission interventions should consider adding mental health components. PMID:25642610

    Background The Center for Medicare and Medicaid Service has identified several quality metrics, including unplanned readmission within 30 days of surgery, to assess and compare surgeons and hospitals. The purpose of this study was to identify the incidence, causes and risk factors for unplanned 30-day readmission after total shoulder arthroplasty. Methods We identified patients undergoing primary elective shoulder arthroplasty performed at American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) participating hospitals in 2013. Cases were stratified by readmission status. Univariate and multivariate analyses were employed to assess patient demographics, comorbidities and operative variables predicting unplanned readmission. Results 2779 patients undergoing shoulder arthroplasty were identified, with 74 (2.66%) requiring unplanned readmissions within 30 days of surgery. The most common surgical causes for unplanned readmission were surgical site infections (18.6%), dislocations (16.3%) and venous thromboembolism (14.0%). Medical causes for readmission were responsible for 51% of unplanned readmissions. Multivariate analysis identified patient age >75 (OR 2.62, 95% CI: 1.27 - 5.41), and ASA class of 3 (OR 1.79, 95% CI: 1.01 - 3.18) or 4 (OR 3.63, 95% CI: 1.31 - 10.08) as independent risk factors for unplanned readmission. Predictive modeling estimated that patients with ASA class of 4 and age >75 are 17.4 times more likely (95% CI 1.77-171.09) to be readmitted within 30 days of shoulder arthroplasty. Conclusion Unplanned readmission after shoulder arthroplasty is infrequent and medical complications account for more than 50% of occurrences. The risk of readmission exponentially increases when age and preoperative comorbidity burden are increased. PMID:27528839

    Abstract This study retrospectively assessed rates and risk factors for all-cause hospital readmission among elderly Medicare beneficiaries with type 2 diabetes mellitus (T2DM) aged ≥65 years. Associations between 30-day readmission and patients' demographic, insurance, index hospital, and clinical characteristics; patient complexities specific to the elderly; and health care utilization were examined using multivariable logistic regressions. Of 202,496 elderly Medicare beneficiaries, 52% were female, 76% were white, the mean age was 75.8 years, and 13.2% had all-cause 30-day readmissions. Elderly patients with cognitive impairment (adjusted odds ratio [aOR]=1.06, 95% confidence interval [CI]=1.01–1.12), falls and falls risk (aOR=1.15, 95% CI=1.08–1.22), polypharmacy (aOR=1.20, 95% CI=1.14–1.27), and urinary incontinence (aOR=1.08, 95% CI=1.01–1.15) were at higher risk for all-cause 30-day readmission than their counterparts without these complexities. As elderly-specific complexities are associated with greater risk for readmission, intervention programs to reduce readmission risk among elderly patients with T2DM should be tailored to suit the needs of elderly patients with extensive complexities.

    Postprocedural revisits, readmissions, and reoperations are commonly tracked quality metrics and have reimbursement and hospital-level comparison implications. Our purpose was to document these rates after pediatric appendectomy and to identify patient factors related to these metrics. This study included 3756 appendectomies performed at a single institution from 2009 to 2013. Data were prospectively collected and clinical events within 30 days of discharge were analyzed. Regression models identified factors associated with each metric. There were 328 returns to the emergency department (8.7%), 128 readmissions (3.4%), and 41 reoperations (1.0%). The main source of readmission was the emergency department (n = 118, 92%). Nearly two-thirds of readmissions were nonoperative (n = 87, 68%) and 12.5 per cent of readmissions were not related to the index appendectomy. Factors associated with readmission include procedure length >70 minutes [odds ratio (OR) 1.89, P = 0.043] and failed nonoperative management of perforated appendicitis (OR 2.97, P = 0.041). The most common indication for reoperation was intra-abdominal abscess (n = 20, 49%), 55 per cent of which were managed with image-guided drainage. In conclusion, although 30-day revisit, readmission, and reoperation rates after appendectomy are low, there are opportunities for improvement. Furthermore, many 30-day readmissions are not related to the index procedure and must be clearly identified to avoid inaccuracies with reimbursement and quality rankings. PMID:27457862

    East Asia is known for its monsoon characteristics, but little research has been performed on the intraseasonal time scale of the East Asian winter monsoon (EAWM). In this paper, the extended reanalysis (ERA)-Interim sub-daily data are used to study the surface air temperature intraseasonal oscillation (ISO) of the EAWM. The results show that the air temperature (2-m level) of the EAWM has a dominant period of 10-30 days. Lake Baikal and south China are the centers of the air temperature ISO. An anomalous low frequency (10-30-day filtered) anticyclone corresponds to the intraseasonal cold air. The 10-30-day filtered cold air spreads from Novaya Zemlya to Lake Baikal and even to South China. The ISO of the Arctic Oscillation (AO) index influences the temperature of the EAWM by stimulating Rossby waves in middle latitude, causing meridional circulation, and eventually leads to the temperature ISO of the EAWM. RegCM4 has good performance for the simulation of the air temperature ISO. The simulated results indicate that the plateau is responsible for the southward propagation of the intraseasonal anticyclone. The anticyclone could not reach South China when there was no plateau in western China and its upper reaches.

    Objective Hypoglycemia is a serious complication of diabetes treatment. This retrospective observational study characterized hypoglycemia-related hospital emergency room (ER) and inpatient (in-pt) admissions and identified risk factors for 30-day all-cause and hypoglycemia-related readmission. Research design and methods 4476 hypoglycemia-related ER and in-pt encounters with discharge dates from 1/1/2009 to 3/31/2014 were identified in a large, multicenter electronic health record database. Outcomes were 30-day all-cause ER/hospital readmission and hypoglycemia-related readmission. Multivariable logistic regression methods identified risk factors for both outcomes. Results 1095 (24.5%) encounters had ER/hospital all-cause readmission within 30 days and 158 (14.4%) of these were hypoglycemia-related. Predictors of all-cause 30-day readmission included recent exposure to a hospital/nursing home (NH)/skilled nursing facility (SNF; OR 1.985, p<0.001); age 25–34 and 35–44 (OR 2.334 and 1.996, respectively, compared with age 65–74, both p<0.001); and African-American (AA) race versus all other race categories (OR 1.427, p=0.011). Other factors positively associated with readmission include chronic obstructive pulmonary disease, cerebrovascular disease, cardiac dysrhythmias, congestive heart disease, hypertension, and mood disorders. Predictors of readmissions attributable to hypoglycemia included recent exposure to a hospital/NH/SNF (OR 2.299, p<0.001), AA race (OR 1.722, p=0.002), age 35–44 (OR 3.484, compared with age 65–74, p<0.001), hypertension (OR 1.891, p=0.019), and delirium/dementia and other cognitive disorders (OR 1.794, p=0.038). Obesity was protective against 30-day hypoglycemia-related readmission (OR 0.505, p=0.017). Conclusions Factors associated with 30-day all-cause and hypoglycemia-related readmission among patients with diabetic hypoglycemia include recent exposure to hospital/SNF/NH, adults <45 years, AAs, and several cardiovascular and

    Introduction Patients with mental health conditions frequently use emergency medical services. Many suffer from substance use and homelessness. If they use the emergency department (ED) as their primary source of care, potentially preventable frequent ED revisits and hospital readmissions can worsen an already crowded healthcare system. However, the magnitude to which homelessness affects health service utilization among patients with mental health conditions remains unclear in the medical community. This study assessed the impact of homelessness on 30-day ED revisits and hospital readmissions among patients presenting with mental health conditions in an urban, safety-net hospital. Methods We conducted a secondary analysis of administrative data on all adult ED visits in 2012 in an urban safety-net hospital. Patient demographics, mental health status, homelessness, insurance coverage, level of acuity, and ED disposition per ED visit were analyzed using multilevel modeling to control for multiple visits nested within patients. We performed multivariate logistic regressions to evaluate if homelessness moderated the likelihood of mental health patients’ 30-day ED revisits and hospital readmissions. Results Study included 139,414 adult ED visits from 92,307 unique patients (43.5±15.1 years, 51.3% male, 68.2% Hispanic/Latino). Nearly 8% of patients presented with mental health conditions, while 4.6% were homeless at any time during the study period. Among patients with mental health conditions, being homeless contributed to an additional 28.0% increase in likelihood (4.28 to 5.48 odds) of 30-day ED revisits and 38.2% increase in likelihood (2.04 to 2.82 odds) of hospital readmission, compared to non-homeless, non-mental health (NHNM) patients as the base category. Adjusted predicted probabilities showed that homeless patients presenting with mental health conditions have a 31.1% chance of returning to the ED within 30-day post discharge and a 3.7% chance of hospital

    Background Geriatric patients with femoral neck fracture (FNF) have unacceptably high rates of postoperative complications and mortality. The purpose of this study was to compare the effects of epidural anesthesia versus peripheral nerve block (PNB) on postoperative outcomes in elderly Chinese patients with FNF. Methods This retrospective study explored mortality and postoperative complications in geriatric patients with FNF who underwent epidural anesthesia or PNB at the Chinese People’s Liberation Army General Hospital from January 2008 to December 2012. The electronic database at the Chinese People’s Liberation Army General Hospital includes discharge records for all patients treated in the hospital. Information on patient demographics, preoperative comorbidity, postoperative complications, type of anesthesia used, and in-hospital, 30-day, and 1-year mortality after surgery was obtained from this database. Results Two hundred and fifty-eight patients were identified for analysis. The mean patient age was 79.7 years, and 71.7% of the patients were women. In-hospital, 30-day, and 1-year postoperative mortality was 4.3%, 12.4%, and 22.9%, respectively, and no differences in mortality or cardiovascular complications were found between patients who received epidural anesthesia and those who received PNB. More patients with dementia or delirium were given PNB. No statistically significant differences were found between groups for other comorbidities or intraoperative parameters. The most common complications were acute cardiovascular events (23.6%), electrolyte disturbances (20.9%), and hypoxemia (18.2%). Patients who received PNB had more postoperative delirium (P=0.027). Postoperative acute respiratory events were more common (P=0.048) and postoperative stroke was less common (P=0.018) in the PNB group. There were fewer admissions to intensive care (P=0.024) in the epidural anesthesia group. Key factors with a negative influence on mortality were acute

    Background Growing scrutiny of readmissions has placed hospitals at the center of readmission prevention. Little is known, however, about hospital nursing - a critical organizational component of hospital service system - in relation to readmissions. Objectives To determine the relationships between hospital nursing factors - nurse work environment, nurse staffing, and nurse education - and 30-day readmissions among Medicare patients undergoing general, orthopedic, and vascular surgery. Method and Design We linked Medicare patient discharge data, multi-state nurse survey data, and American Hospital Association Annual Survey data. Our sample included 220,914 Medicare surgical patients and 25,082 nurses from 528 hospitals in four states (CA, FL, NJ, & PA). Risk-adjusted robust logistic regressions were used for analyses. Results The average 30-day readmission rate was 10% in our sample (general surgery: 11%; orthopedic surgery: 8%; vascular surgery: 12%). Readmission rates varied widely across surgical procedures and could be as high as 26% (upper limb and toe amputation for circulatory system disorders). Each additional patient per nurse increased the odds of readmission by 3% (OR=1.03, 95% CI: 1.00-1.05). Patients cared in hospitals with better nurse work environments had lower odds of readmission (OR=0.97, 95% CI: 0.95-0.99). Administrative support to nursing practice (OR=0.96, 95% CI: 0.94-0.99) and nurse-physician relations (OR=0.97, 95% CI: 0.95-0.99) were two main attributes of the work environment that were associated with readmissions. Conclusions Better nurse staffing and work environment were significantly associated with 30-day readmission, and can be considered as system-level interventions to reduce readmissions and associated financial penalties.

    Background Measures of socioeconomic disadvantage may enable improved targeting of programs to prevent rehospitalizations, but obtaining such information directly from patients can be difficult. Measures of US neighborhood socioeconomic disadvantage are more readily available, although rarely employed clinically. Objective To evaluate the association between neighborhood socioeconomic disadvantage at the census block-group level, as measured by Singh’s validated Area Deprivation Index (ADI), and 30-day rehospitalization. Design Retrospective cohort study Setting United States Patients Random 5% national sample of fee-for-service Medicare patients discharged with congestive heart failure, pneumonia or myocardial infarction, 2004–2009 (N = 255,744) Measurements 30-day rehospitalizations. Medicare data were linked to 2000 Census data to construct an ADI for each patient’s census block-group, which were then sorted into percentiles by increasing ADI. Relationships between neighborhood ADI grouping and rehospitalization were evaluated using multivariate logistic regression models, controlling for patient sociodemographics, comorbidities/severity, and index hospital characteristics. Results The 30-day rehospitalization rate did not vary significantly across the least disadvantaged 85% of neighborhoods, which had an average rehospitalization rate=21%. However, within the most disadvantaged 15% of neighborhoods, rehospitalization rates rose from 22% to 27% with worsening ADI. This relationship persisted after full adjustment, with the most disadvantaged neighborhoods having a rehospitalization risk (adjusted risk ratio = 1.09, confidence interval 1.05–1.12) similar to that of chronic pulmonary disease (1.06, 1.04–1.08) and greater than that of diabetes (0.95, 0.94–0.97). Limitations No direct markers of care quality, access Conclusions Residence within a disadvantaged US neighborhood is a rehospitalization predictor of magnitude similar to chronic pulmonary

    Background Among patients who are discharged from the Emergency Department (ED), about 3% return within 30 days. Revisits can be related to the nature of the disease, medical errors, and/or inadequate diagnoses and treatment during their initial ED visit. Identification of high-risk patient population can help device new strategies for improved ED care with reduced ED utilization. Methods and Findings A decision tree based model with discriminant Electronic Medical Record (EMR) features was developed and validated, estimating patient ED 30 day revisit risk. A retrospective cohort of 293,461 ED encounters from HealthInfoNet (HIN), Maine's Health Information Exchange (HIE), between January 1, 2012 and December 31, 2012, was assembled with the associated patients' demographic information and one-year clinical histories before the discharge date as the inputs. To validate, a prospective cohort of 193,886 encounters between January 1, 2013 and June 30, 2013 was constructed. The c-statistics for the retrospective and prospective predictions were 0.710 and 0.704 respectively. Clinical resource utilization, including ED use, was analyzed as a function of the ED risk score. Cluster analysis of high-risk patients identified discrete sub-populations with distinctive demographic, clinical and resource utilization patterns. Conclusions Our ED 30-day revisit model was prospectively validated on the Maine State HIN secure statewide data system. Future integration of our ED predictive analytics into the ED care work flow may lead to increased opportunities for targeted care intervention to reduce ED resource burden and overall healthcare expense, and improve outcomes.

    The hypothesis that reducing muscle compartment by a long-term exposure to microgravity would cause increased leg venous compliance was tested in eight men who were assessed for vascular compliance and for serial circumferences of the calf before and after 30 days of continuous 6-deg head-down bed rest. It was found that head-down bed rest caused decreases in the calculated calf volume and the calf-muscle compartment, as well as increases in calf compliance. The percent increases in calf compliance correlated significantly with decreases in calf muscle compartment.

    OBJECTIVE The purpose of this study was to better understand the relationship between nurse staffing and 30-day excess readmission ratios for patients with heart failure in the top US adult cardiology and heart surgery hospitals. BACKGROUND Heart failure is the most common cause of hospitalization for patients older than 65 years and is the most frequent diagnosis associated with 30-day hospital readmission in the United States. METHODS A secondary data analysis was conducted using nurse staffing data from 661 cardiology and heart surgery hospitals from the 2013 US News & World Report “Best Hospitals” survey. These data were combined with excess readmission ratios from the Centers for Medicare & Medicaid Services Hospital Compare database from 2013. An independent-samples t test was used to compare staffing (low/high) and excess hospital readmissions rates. RESULTS A significant difference (P = .021) was found between the low nurse staffing group (n = 358) and the high nurse staffing group (n = 303). Hospitals with a lower nurse staffing index had a significantly higher excess readmission rate. CONCLUSION These data provide further support to the body of research showing a positive relationship between nurse staffing and positive outcomes. PMID:26579974

    Hospitals are under great pressure to reduce readmissions of patients. Being able to reliably predict patients at increased risk for rehospitalization would allow for tailored interventions to be offered to them. This requires the creation of a functional predictive model specifically designed to support real-time clinical operations. A predictive model for readmissions within 30 days of discharge was developed using retrospective data from 45,924 MGH admissions between 2/1/2012 and 1/31/2013 only including factors that would be available by the day after admission. It was then validated prospectively in a real-time implementation for 3,074 MGH admissions between 10/1/2013 and 10/31/2013. The model developed retrospectively had an AUC of 0.705 with good calibration. The real-time implementation had an AUC of 0.671 although the model was overestimating readmission risk. A moderately discriminative real-time 30-day readmission predictive model can be developed and implemented in a large academic hospital. PMID:25954346

    Purpose: To create, on the basis of available data, a mathematical model to describe the tumor stage- and field size-dependent risks/benefits of postoperative radiotherapy (PORT) for non-small-cell lung cancer (NSCLC), and to assess whether this simple model can accurately describe the reported changes in overall survival. Methods and Materials: The increase in overall survival afforded by PORT is assumed equal to the increase in cancer-specific survival minus the rate of RT-induced mortality. The increase in cancer-specific survival is the product of the probabilities of (residual local disease) x (sterilization of residual disease with PORT) x (absence of metastatic disease). Data were extracted from the literature to estimate these probabilities. Different models were considered to relate the RT-induced mortality to field size. Results: The rate of RT-induced mortality seems to be proportional to the cube of the field size. When these mortality rates are included in the model, the predicted changes in overall survival approximate the literature values. Conclusion: Clinical data can be explained by a simple model that suggests that RT-induced mortality is strongly dependent on field size and at least partly offsets the benefit afforded by PORT. Smaller RT fields, tailored to treat the areas most at risk for recurrence, provide the highest therapeutic ratio. The data used do not reflect the impact of chemotherapy, which will reduce the rate of distant metastases and enhance the efficacy of RT.

    Importance Reducing early (<30 days) hospital readmissions is a policy priority aimed at improving healthcare quality. The Cumulative Complexity Model conceptualizes patient context. It predicts that highly supportive discharge interventions will enhance patient capacity to enact burdensome self-care and avoid readmissions. Objectives To synthesize the evidence of the efficacy of interventions to reduce early hospital readmissions and identify intervention features—including their impact on treatment burden and on patients’ capacity to enact post-discharge self-care—that might explain their varying effects. Data Sources We searched electronic databases (1990 until April 1st, 2013), contacted experts, and reviewed bibliographies. Study Selection Randomized trials that assessed the effect of interventions on all-cause or unplanned readmissions within 30 days of discharge in adult patients admitted to the hospital for a medical or surgical cause for > 24 hours and discharged to home. Data extraction and Synthesis Reviewer pairs extracted trial characteristics and used an activity-based coding strategy to characterize the interventions; fidelity was confirmed with authors. Blinded to trial outcomes, reviewers noted the extent to which interventions placed additional work on patients after discharge or supported their capacity for self-care in accordance with the Cumulative Complexity Model. Main Outcome Relative risk of all-cause or unplanned readmission with or without out of hospital deaths at 30 days post-discharge. Results In 42 trials, the tested interventions prevented early readmissions [pooled random effects relative risk (RR) 0.82, 95% CI 0.73 to 0.91; p=.03; I2= 32%], a finding that was consistent across patient subgroups. Trials published before 2002 reported interventions that were 1.6 times more effective than those tested later (pinteraction = .01). In exploratory subgroup analyses, interventions with many components (pinteraction <.01), involving

    Characterization of cortisol production, regulation and function is of considerable interest and relevance given its ubiquitous role in virtually all aspects of physiology, health and disease risk. The quantification of cortisol concentration in hair has been proposed as a promising approach for the retrospective assessment of integrated, long-term cortisol production. However, human research is still needed to directly test and validate current assumptions about which aspects of cortisol production and regulation are reflected in hair cortisol concentrations (HCC). Here, we report findings from a validation study in a sample of 17 healthy adults (mean±SD age: 34±8.6 yrs). To determine the extent to which HCC captures cumulative cortisol production, we examined the correspondence of HCC, obtained from the first 1cm scalp-near hair segment, assumed to retrospectively reflect 1-month integrated cortisol secretion, with 30-day average salivary cortisol area-under-the curve (AUC) based on 3 samples collected per day (on awakening, +30min, at bedtime) and the average of 4 weekly 24-h urinary free cortisol (UFC) assessments. To further address which aspects of cortisol production and regulation are best reflected in the HCC measure, we also examined components of the salivary measures that represent: (1) production in response to the challenge of awakening (using the cortisol awakening response [CAR]), and (2) chronobiological regulation of cortisol production (using diurnal slope). Finally, we evaluated the test-retest stability of each cortisol measure. Results indicate that HCC was most strongly associated with the prior 30-day integrated cortisol production measure (average salivary cortisol AUC) (r=0.61, p=0.01). There were no significant associations between HCC and the 30-day summary measures using CAR or diurnal slope. The relationship between 1-month integrated 24-h UFC and HCC did not reach statistical significance (r=0.30, p=0.28). Lastly, of all cortisol

    Background Unplanned hospital readmission following orthopedic procedures results in significant expenditures for the Medicare population. In order to reduce expenditures, hospital readmission has become an important quality metric for Medicare patients. The purpose of the present study is to determine the incidence and risk factors for 30-day readmissions after hip fracture surgery. Methods Patients over the age of 18 years who underwent hip fracture surgery, including open reduction internal fixation (ORIF), intramedullary nailing, hemi-arthroplasty, or total hip arthroplasty, between the years 2012 and 2013 were identified from the American College of Surgeons National Surgical Quality improvement Program (NSQIP) database. Overall, 17,765 patients were identified. Univariate and multivariate analyses were performed in order to determine patient and surgical factors associated with 30-day readmission. Results There were 1503 patients (8.4%) readmitted within 30-days of their index procedure. Of the patients with a reason listed for readmission, 27.4% were for procedurally related reasons, including wound complications (16%), peri-prosthetic fractures (4.5%) and prosthetic dislocations (6%). 72.6% of readmissions were for medical reasons, including sepsis (7%), pneumonia (14%), urinary tract infection (6.3%), myocardial infarction (2.7%), renal failure (2.7%), and stroke (2.3%). In the subsequent multivariate analysis, pre-operative dyspnea, COPD, hypertension, disseminated cancer, a bleeding disorder, pre-operative hematocrit of <36, pre-operative creatinine of >1.2, an ASA class of 3 or 4, and the operative procedure type were each independently associated with readmissions risk (p<0.05 for each). Conclusions The overall rate of readmission following hip fracture surgery was moderate. Surgeons should consider discharge optimization in the at risk cohorts identified here, particularly patients with multiple medical comorbidities or an elevated ASA class, and

    The purpose of this quality improvement project was to determine whether use of aspects of a transitional care model by nurse navigators would affect 30-day readmission rates in hospitalized ischemic stroke patients discharged home with self-care. Thirty-day readmission rates and emergency department (ED) visits were compared before, during, and after the implementation of the revised discharge process. Comparative analysis demonstrated reductions in readmissions and in ED visits. Thirty-day readmission rates to our hospital decreased from 9.39% to 3.24% when comparing pre- with postintervention data. Thirty-day ED visit rates to all state hospitals decreased from 16.36% to 12.08% when comparing pre- with postintervention data. PMID:24322371

    Microgravity leads to cardiovascular deconditioning in humans, which is manifested by post-flight reduction of orthostatic tolerance and upright exercise capacity. During upright posture on Earth, blood pressures are greater in the feet than at heart or head levels due to gravity's effects on columns of blood in the body. During exposure to Microgravity, all gravitational blood pressures disappear. Presently, there is no exercise hardware available for space flight to provide gravitational blood pressures to tissues of the lower body. We hypothesized that 40 minutes of supine treadmill running per day in a LBNP chamber at 1.0 to 1.2 body weight (approximately 50 - 60 mm Hg LBNP) with a 5 min resting, nonexercise LBNP exposure at 50 mm Hg after the exercise session will maintain aerobic fitness orthostatic tolerance, and selected parameters of musculoskeletal function during 30 days of bed rest (simulated microgravity). This paper is an interim report of some of our findings on 16 subjects.

    A fiberglass system was previously described, using which quantitative physiological measurements could be made to study the effects of weightlessness on 10 to 14 kg adult monkeys maintained in comfortable restraint under space flight conditions. Recent improvements in the system have made it possible to obtain continuous measurements of respiratory gas exchange, cardiovascular function, and mineral balance for periods of up to 30 days on pig-tailed monkeys. It has also been possible to operate two pods which share one set of instrumentation, thereby permitting simultaneous measurements to be made on two animals by commutating signal outputs from the pods. In principle, more than two pods could be operated in this fashion. The system is compatible with Spacelab design. Representative physiological data from ground tests of the system are presented.

    Bed rest studies provide an important tool for modeling physiological changes that occur during spaceflight. Markers of bone metabolism and nutritional status were evaluated in 12 subjects (8 men, 4 women; ages 25–49 yr) who participated in a 30-day −6° head-down-tilt diet-controlled bed rest study. Blood and urine samples were collected twice before, once a week during, and twice after bed rest. Data were analyzed using a mixed-effects linear regression with a priori contrasts comparing all days to the second week of the pre-bed rest acclimation period. During bed rest, all urinary markers of bone resorption increased ∼20% (P < 0.001), and serum parathyroid hormone decreased ∼25% (P < 0.001). Unlike longer (>60 days) bed rest studies, neither markers of oxidative damage nor iron status indexes changed over the 30 days of bed rest. Urinary oxalate excretion decreased ∼20% during bed rest (P < 0.001) and correlated inversely with urinary calcium (R = −0.18, P < 0.02). These data provide a broad overview of the biochemistry associated with short-duration bed rest studies and provide an impetus for using shorter studies to save time and costs wherever possible. For some effects related to bone biochemistry, short-duration bed rest will fulfill the scientific requirements to simulate spaceflight, but other effects (antioxidants/oxidative damage, iron status) do not manifest until subjects are in bed longer, in which case longer studies or other analogs may be needed. Regardless, maximizing research funding and opportunities will be critical to enable the next steps in space exploration. PMID:22995395

    Clinical mastitis results in considerable economic losses for dairy producers and is most commonly diagnosed in early lactation. The objective of this research was to estimate the economic impact of clinical mastitis occurring during the first 30 days of lactation for a representative US dairy. A deterministic partial budget model was created to estimate direct and indirect costs per case of clinical mastitis occurring during the first 30 days of lactation. Model inputs were selected from the available literature, or when none were available, from herd data. The average case of clinical mastitis resulted in a total economic cost of $444, including $128 in direct costs and $316 in indirect costs. Direct costs included diagnostics ($10), therapeutics ($36), non-saleable milk ($25), veterinary service ($4), labor ($21), and death loss ($32). Indirect costs included future milk production loss ($125), premature culling and replacement loss ($182), and future reproductive loss ($9). Accurate decision making regarding mastitis control relies on understanding the economic impacts of clinical mastitis, especially the longer term indirect costs that represent 71% of the total cost per case of mastitis. Future milk production loss represents 28% of total cost, and future culling and replacement loss represents 41% of the total cost of a case of clinical mastitis. In contrast to older estimates, these values represent the current dairy economic climate, including milk price ($0.461/kg), feed price ($0.279/kg DM (dry matter)), and replacement costs ($2,094/head), along with the latest published estimates on the production and culling effects of clinical mastitis. This economic model is designed to be customized for specific dairy producers and their herd characteristics to better aid them in developing mastitis control strategies. PMID:26596651

    Background and purpose Hip fracture (HF) in frail elderly patients is associated with poor physical recovery and death. There is often postoperative blood loss and the hemoglobin (Hb) threshold for red blood cell (RBC) transfusions in these patients is unknown. We investigated whether RBC transfusion strategies were associated with the degree of physical recovery or with reduced mortality after HF surgery. Patients and methods We enrolled 284 consecutive post-surgical HF patients (aged ≥ 65 years) with Hb levels < 11.3 g/dL (7 mmol/L) who had been admitted from nursing homes or sheltered housing. Allocation was stratified by residence. The patients were randomly assigned to either restrictive (Hb < 9.7 g/dL; < 6 mmol/L) or liberal (Hb < 11.3 g/dL; < 7 mmol/L) RBC transfusions given within the first 30 days postoperatively. Follow-up was at 90 days. Results No statistically significant differences were found in repeated measures of daily living activities or in 90-day mortality rate between the restrictive group (where 27% died) and the liberal group (where 21% died). Per-protocol 30-day mortality was higher with the restrictive strategy (hazard ratio (HR) = 2.4, 95% CI: 1.1–5.2; p = 0.03). The 90-day mortality rate was higher for nursing home residents in the restrictive transfusion group (36%) than for those in the liberal group (20%) (HR = 2.0, 95% CI: 1.1–3.6; p = 0.01). Interpretation According to our Hb thresholds, recovery from physical disabilities in frail elderly hip fracture patients was similar after a restrictive RBC transfusion strategy and after a liberal strategy. Implementation of a liberal RBC transfusion strategy in nursing home residents has the potential to increase survival. PMID:25586270

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p < 0.001 for each). Postoperative pneumonia (OR 4.294, p < 0.001), urinary tract infection (OR 4.262, p < 0.001), and sepsis (OR 2.616, p = 0.006) also independently increased the readmission risk. Independent patient risk factors for unplanned readmission included Native American race (OR 2.363, p = 0.019), steroid use > 10 days (OR 1.411, p = 0

    Postoperative pulmonary complications are a major problem after upper abdominal or thoracoabdominal surgery. They lead to a prolonged ICU stay as well as increased costs and are one of the main causes of early postoperative mortality. Even after uncomplicated operations, postoperative hypoxemia occurs in 30-50% of patients. Acute respiratory failure involves a disturbance in gas exchange. The mortality ranges from 10 to 60% according to the severity of respiratory failure. The most important complications are interstitial and alveolar pulmonary edema, atelectasis, postoperative pneumonia, hypoventilation, and aspiration. Preoperative optimization, postoperative prophylaxis according to a stepwise approach, and early mobilization decrease the rate of complications. PMID:16575614

    Background Myocardial injury after non-cardiac surgery (MINS) is defined as troponin elevation of ≥0.03 ng/mL associated with 3.87-fold increase in early mortality. We sought to determine the impact of cardiology intervention on mortality in patients who developed MINS after general thoracic surgery. Methods A retrospective review was performed in patients over 5 years. Troponin was routinely measured and levels ≥0.04 ng/mL classified as positive. Data acquisition and mortality status was obtained via medical records and NHS tracing systems. Thirty-day mortality was compared on MINS cohort using Fisher’s exact square testing and logistic regression analysis. Results Troponin levels were measured in 491 (96%) of 511 patients. Eighty (16%) patients fulfilled the MINS criteria. Sixty-one (76%) received early cardiology consult and “myocardial infarction” stated in four (5%) patients. Risk assessment (for AMI) was undertaken; 20 (25%) patients were commenced on aspirin, four (5%) on β-blockers and one (1%) underwent percutaneous coronary intervention. Forty-nine (61%) patients received primary risk factor modifications and 26 (33%) had outpatient follow-up. There were no significant differences in the proportion of patients who died within 30 days post-operatively in the MINS group of 2.6% compared to the non-MINS group of 1.6% (P=0.625). The odds ratio for 30-day mortality in the MINS group was 1.69 (95% CI: 0.34 to 8.57, P=0.522). Conclusions MINS is common after general thoracic surgery. Early cardiology intervention reduced the expected hazard ratio of early death from 3.87 to an odds ratio of 1.69 with no significant difference in 30-day mortality for patients who developed MINS.

    2016-01-01

    Objectives Later weekday of surgery for oesophageal cancer seems to increase 5-year mortality, but the mechanisms are unclear. We hypothesised that early postoperative reoperations and mortality might explain this association, since reoperation after oesophagectomy decreases long-term prognosis, and later weekday of elective surgery increases 30-day mortality. Design This was a population-based cohort study during the study period 1987–2014. Setting All Swedish hospitals conducting elective surgery for oesophageal cancer in Sweden. Participants Included were 1748 patients, representing almost all (98%) patients who underwent elective surgery for oesophageal cancer in Sweden during 1987–2010, with follow-up until 2014. Primary and secondary outcome measures The risk of reoperation or mortality within 30 days of oesophageal cancer surgery was assessed in relation to weekday of surgery by calculating ORs with 95% CIs using multivariable logistic regression. ORs were adjusted for age, comorbidity, tumour stage, histology, neoadjuvant therapy and surgeon volume. Results Surgery Wednesday to Friday did not increase the risk of reoperation or mortality compared with surgery Monday to Tuesday (OR=0.99, 95% CI 0.75 to 1.31). A decreased point estimate of reoperation (OR=0.88, 95% CI 0.64 to 1.21) was counteracted by an increased point estimate of mortality (OR=1.28, 95% CI 0.83 to 1.99). ORs did not increase from Monday to Friday when each weekday was analysed separately. There was no association between weekday of surgery and reoperation specifically for anastomotic leak, laparotomy or wound infection. Stratification for surgeon volume did not reveal any clear associations between weekday of surgery and risk of 30-day reoperation or mortality. Conclusions Weekday of oesophageal cancer surgery does not seem to influence the risk of reoperation or mortality within 30 days of surgery, and thus cannot explain the association between weekday of surgery and long

    The LACE index (length of stay, acuity of admission, Charlson comorbidity index, CCI, and number of emergency department visits in preceding 6 months) derived in Canada is simple and may have clinical utility in Singapore to predict readmission risk. We compared the performance of the LACE index with a derived model in identifying 30-day readmissions from a population of general medicine patients in Singapore. Additional variables include patient demographics, comorbidities, clinical and laboratory variables during the index admission, and prior healthcare utilization in the preceding year. 5,862 patients were analysed and 572 patients (9.8%) were readmitted in the 30 days following discharge. Age, CCI, count of surgical procedures during index admission, white cell count, serum albumin, and number of emergency department visits in previous 6 months were significantly associated with 30-day readmission risk. The final logistic regression model had fair discriminative ability c-statistic of 0.650 while the LACE index achieved c-statistic of 0.628 in predicting 30-day readmissions. Our derived model has the advantage of being available early in the admission to identify patients at high risk of readmission for interventions. Additional factors predicting readmission risk and machine learning techniques should be considered to improve model performance. PMID:26682212

    The LACE index (length of stay, acuity of admission, Charlson comorbidity index, CCI, and number of emergency department visits in preceding 6 months) derived in Canada is simple and may have clinical utility in Singapore to predict readmission risk. We compared the performance of the LACE index with a derived model in identifying 30-day readmissions from a population of general medicine patients in Singapore. Additional variables include patient demographics, comorbidities, clinical and laboratory variables during the index admission, and prior healthcare utilization in the preceding year. 5,862 patients were analysed and 572 patients (9.8%) were readmitted in the 30 days following discharge. Age, CCI, count of surgical procedures during index admission, white cell count, serum albumin, and number of emergency department visits in previous 6 months were significantly associated with 30-day readmission risk. The final logistic regression model had fair discriminative ability c-statistic of 0.650 while the LACE index achieved c-statistic of 0.628 in predicting 30-day readmissions. Our derived model has the advantage of being available early in the admission to identify patients at high risk of readmission for interventions. Additional factors predicting readmission risk and machine learning techniques should be considered to improve model performance. PMID:26682212

  2. Does a skeletonized internal thoracic artery give fewer postoperative complications than a pedicled artery for patients undergoing coronary artery bypass grafting?

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'Does a skeletonized internal thoracic artery (ITA) give fewer postoperative complications than a pedicled artery for patients undergoing coronary artery bypass grafting?' Altogether, 98 papers were found using the reported search, of which 11 represented the best evidence to answer the clinical question. Papers about patency of skeletonized versus pedicled internal thoracic artery were excluded. The analysed complications were essentially mediastinitis, superficial sternal infection, wound infection, chest pain and pulmonary function. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Grafts used were either single ITA (LITA or RITA, left or right, respectively) or bilateral ITAs (BITAs). One prospective randomized controlled trial was identified, which found that benefits of skeletonized harvesting included increased graft length, increased graft flow and decreased incidence of mediastinitis. All of the six studies concerning wound infection demonstrate fewer complications when ITA is skeletonized. One of the three papers describing postoperative mortality demonstrated lower 30-day mortality, but there was no long-term analysis. Three studies describing postoperative chest pain reported a lower score on the visual analogue scale (VAS) within 30 days. One of them indicates that the pedicled group has a significantly greater VAS, pain disability index and short-form McGill Pain questionnaire score at 1 and 3 months. The hospital stay was shorter for three studies conducted on this subject. One study about pulmonary function reported a better ratio of pre- versus postoperative values of forced vital capacity. Despite longer operating times, skeletonization leads to fewer wound infections, reduced chest pain, allows a shorter hospital stay and better

  3. African Easterly Waves in 30-day High-Resolution Global Simulations: A Case Study During the 2006 NAMMA Period

    2010-01-01

    In this study, extended -range (30 -day) high-resolution simulations with the NASA global mesoscale model are conducted to simulate the initiation and propagation of six consecutive African easterly waves (AEWs) from late August to September 2006 and their association with hurricane formation. It is shown that the statistical characteristics of individual AEWs are realistically simulated with larger errors in the 5th and 6th AEWs. Remarkable simulations of a mean African easterly jet (AEJ) are also obtained. Nine additional 30 -day experiments suggest that although land surface processes might contribute to the predictability of the AEJ and AEWs, the initiation and detailed evolution of AEWs still depend on the accurate representation of dynamic and land surface initial conditions and their time -varying nonlinear interactions. Of interest is the potential to extend the lead time for predicting hurricane formation (e.g., a lead time of up to 22 days) as the 4th AEW is realistically simulated.

    In recent years, there has been increased interest in stemming the tide of hospital readmissions in an attempt to improve quality of care. This study presents the Phase I results of a resident-led quality improvement initiative to determine the percentage of and risk factors for same-cause readmissions (SCRs; defined as hospital readmission within 30 days of hospital discharge for treatment of the same condition) to the internal medicine service of a multispecialty teaching hospital in central Texas. Results indicate that patients diagnosed with chronic obstructive pulmonary disease/asthma or anemia may be at increased risk for SCRs. Those patients who are insured by Medicaid and those who require assistance from social services also demonstrated an increased risk for SCRs. This study appears to be the first resident-led initiative in the field to examine 30-day SCRs to an internal medicine service for demographic and clinical risk factors. PMID:23550215

    There is a need to increase people’s engagement with and connection to nature, both for human well-being and the conservation of nature itself. In order to suggest ways for people to engage with nature and create a wider social context to normalise nature engagement, The Wildlife Trusts developed a mass engagement campaign, 30 Days Wild. The campaign asked people to engage with nature every day for a month. 12,400 people signed up for 30 Days Wild via an online sign-up with an estimated 18,500 taking part overall, resulting in an estimated 300,000 engagements with nature by participants. Samples of those taking part were found to have sustained increases in happiness, health, connection to nature and pro-nature behaviours. With the improvement in health being predicted by the improvement in happiness, this relationship was mediated by the change in connection to nature. PMID:26890891

  6. Evaluation of a Pharmacist-Specific Intervention on 30-Day Readmission Rates for High-Risk Patients with Pneumonia

    PubMed Central

    Carroll, Douglas N.; Pinner, Nathan A.

    2015-01-01

    Background: Pharmacist interventions have been shown to have an impact on reducing readmission rates, however further research is necessary to target resources to high-risk populations and determine the most effective bundle of interventions. Objective: To evaluate the effect of a pharmacist-bundled intervention on 30-day readmission rates for high-risk patients with pneumonia. Methods: A pilot study with a historical control conducted at a community, teaching-affiliated medical center. Up to 65 selected subjects were included if they had pneumonia and any of the following high-risk criteria: admission within 6 months, at least 5 scheduled home medications, chronic obstructive pulmonary disease (COPD), or heart failure. A retrospective chart review was conducted to compile the historical control group that received usual care between June and November 2013. Patients admitted from December 2013 through March 2014 were reviewed to receive a bundled intervention. The primary outcome was 30-day readmission rates. Risk factors and reasons for readmission, pharmacist clinical interventions, and the time interval between discharge and readmission were also evaluated. Results: A trend toward a reduced 30-day readmission rate was observed in the intervention group (n = 43) compared to those who received usual care (n = 65) (27.9% vs 40.0%; relative risk [RR], 0.6977; 95% CI, 0.3965–1.2278; P = .2119). The most commonly identified high-risk inclusion criteria were having at least 5 scheduled home medications and COPD. The time interval between discharge and readmission did not considerably differ between groups (10.8 vs 10.6 days). Conclusions: The pharmacist-bundled intervention was associated with a reduced 30-day readmission rate for high-risk patients with pneumonia. PMID:26823619

  7. Marijuana use motives: concurrent relations to frequency of past 30-day use and anxiety sensitivity among young adult marijuana smokers.

    Bonn-Miller, Marcel O; Zvolensky, Michael J; Bernstein, Amit

    2007-01-01

    The present investigation examined two theoretically relevant aspects of marijuana motives using the Marijuana Motives Measure (MMM) [Simons, J., Correia, C. J., Carey, K. B., & Borsari, B. E. (1998). Validating a five-factor marijuana motives measure: Relations with use, problems, and alcohol motives. Journal of Counseling Psychology 45, 265-273] among 141 (78 female) young adults (M(age)=20.17, S.D.=3.34). The first objective was to evaluate the incremental validity of marijuana motives in relation to frequency of past 30-day use after controlling for the theoretically relevant factors of the number of years using marijuana (lifetime), current levels of alcohol, as well as tobacco smoking use. As expected, coping, enhancement, social, and expansion motives each were uniquely and significantly associated with past 30-day marijuana use over and above the covariates; conformity motives were not a significant predictor. A second aim was to explore whether coping, but no other marijuana motive, was related to the emotional vulnerability individual difference factor of anxiety sensitivity (fear of anxiety). As hypothesized, after controlling for number of years using marijuana (lifetime), past 30-day marijuana use, current levels of alcohol consumption, and cigarettes smoked per day, anxiety sensitivity was incrementally and uniquely related to coping motives for marijuana use, but not other motives. These results are discussed in relation to the clinical implications of better understanding the role of motivation for marijuana use among emotionally vulnerable young adults. PMID:16647822

  8. Predictors of mortality following primary hip and knee replacement in the aged

    PubMed Central

    2013-01-01

    Background and purpose High age is associated with increased postoperative mortality, but the factors that predict mortality in older hip and knee replacement recipients are not known. Methods Preoperative clinical and operative data on 1,998 primary total hip and knee replacements performed for osteoarthritis in patients aged ≥ 75 years in a single institution were collected from a joint replacement database and compoared with mortality data. Average follow-up was 4.2 (2.2–7.6) years for the patients who survived. Factors associated with mortality were analyzed using Cox regression analysis, with adjustment for age, sex, operated joint, laterality, and anesthesiological risk score. Results Mortality was 0.15% at 30 days, 0.35% at 90 days, 1.60% at 1 year, 7.6% at 3 years, and 16% at 5 years, and was similar following hip and knee replacement. Higher age, male sex, American Society of Anesthesiologists risk score of > 2, use of walking aids, preoperative walking restriction (inability to walk or ability to walk indoors only, compared to ability to walk > 1 km), poor clinical condition preoperatively (based on clinical hip and knee scores or clinical severity of osteoarthritis), preoperative anemia, severe renal insufficiency, and use of blood transfusions were associated with higher mortality. High body mass index had a protective effect in patients after hip replacement. Interpretation Postoperative mortality is low in healthy old joint replacement recipients. Comorbidities and functional limitations preoperatively are associated with higher mortality and warrant careful consideration before proceeding with joint replacement surgery. PMID:23244785

    2010-10-01

    The purpose of this study is to determine if the intermittent leg muscular strength exercise and bicycle ergometry exercise could attenuate cardiovascular deconditioning induced by prolonged -6° head-down bed rest (HDBR). Fifteen male subjects were randomly allocated into group A ( n=5, 30 days HDBR without exercise), group B ( n=5, 30 days HDBR with leg muscular strength exercise) and group C ( n=5, 30 days HDBR with bicycle ergometry exercise). The orthostatic tolerance (OT) was determined by +75°/20 min head-up tilt (HUT) test and the submaximal exercise capacity was determined by bicycle ergometry before and after HDBR. The results were as follows: (1) Compared with that before HDBR, OT time decreased dramatically by 57.6% ( p<0.001) after HDBR in group A, while it decreased by 36.4% ( p=0.084) in group B and by 34.7% ( p=0.062) in group C. (2) Compared with that before HDBR, the submaximal exercise time decreased significantly by 17.7% ( p<0.05) and 21.1% ( p<0.05) in groups A and B, respectively, after HDBR. However, it had no change (+1.3%, p>0.77) in group C. (3) compared with that before HDBR, the changes of heart rate (HR) and blood pressure were slightly improved in group B and C, while deteriorated in group A during orthostatic test and exercise test after HDBR. The results indicate that leg muscular strength exercise and bicycle ergometry exercise could partially attenuate the cardiovascular deconditioning induced by 30 d HDBR, and the latter exercise training could fully provide the protection for the loss of exercise capacity.

    In the summer of 1969, a deep submersible drifted for 30 days below the surface of the Gulf Stream, while operated by a six man crew. The main purpose of the mission was oceanographic research. The crew's activities and completely self-contained environment resembled those of a space station such as Skylab. Because of these similarities aspects of onboard vehicle maintenance during the actual conduct of a scientific mission were investigated. The maintainability study was accomplished in six distinct phases. Two useful plots of manpower distribution were developed. A maintenance action summary is presented in a table.

    The percutaneous lead management kit (PLMK) was developed for the HeartMate 2 (HM2) left ventricular assist device (LVAD) to reduce trauma at the exit site and to maintain a clean environment. REduce Driveline Trauma through StabIlization and Exit Site ManagemenT (RESIST) was a multicenter, prospective, nonrandomized study designed to evaluate the feasibility of the PLMK for managing the HM2 driveline exit site. Fifty patients were enrolled at five sites at a median of 495 days post-HM2 implant; 92% (46 of 50) of patients used the PLMK for a minimum of 30 days. At 30 days, more patients found the PLMK to be extremely comfortable (80% vs. 37%, p < 0.001) and extremely effective at stabilizing the driveline (82% vs. 40%, p < 0.001) compared with each center's standard of care. Frequency of dressing changes was 6-7 days or higher for 85% of the patients with PLMK. Three patients developed driveline infection while on PLMK (6%, 0.15 events per patient year), and 35 patients continued to use the PLMK after 6 months. The PLMK is easy to use, increases patient comfort, and increases driveline stability with a dressing change frequency of 6-7 days. PMID:27111738

    The 2 objectives of this subchronic study were to determine the arsenite drinking water exposure dependent increases in female C3H mouse liver and lung tissue arsenicals and to characterize the dose response (to 0, 0.05, 0.25, 1, 10, and 85 ppm arsenite in drinking water for 30 days and a purified AIN-93M diet) for genomic mouse lung expression patterns. Mouse lungs were analyzed for inorganic arsenic, monomethylated, and dimethylated arsenicals by hydride generation atomic absorption spectroscopy. The total lung mean arsenical levels were 1.4, 22.5, 30.1, 50.9, 105.3, and 316.4 ng/g lung tissue after 0, 0.05, 0.25, 1, 10, and 85 ppm, respectively. At 85 ppm, the total mean lung arsenical levels increased 14-fold and 131-fold when compared to either the lowest noncontrol dose (0.05 ppm) or the control dose, respectively. We found that arsenic exposure elicited minimal numbers of differentially expressed genes (DEGs; 77, 38, 90, 87, and 87 DEGs) after 0.05, 0.25, 1, 10, and 85 ppm, respectively, which were associated with cardiovascular disease, development, differentiation, apoptosis, proliferation, and stress response. After 30 days of arsenite exposure, this study showed monotonic increases in mouse lung arsenical (total arsenic and dimethylarsinic acid) concentrations but no clear dose-related increases in DEG numbers.

    Purpose To determine the changes in dry eye disease (DED) severity and the percentage of cells expressing HLA-DR on the ocular surface following treatment with lubricant eyedrops containing polyethylene glycol and propylene glycol (PEG/PG) and the gelling agent hydroxypropyl guar (HP-Guar). Patients and methods Nineteen patients with DED used PEG/PG + HP-Guar eyedrops four times per day for 30 days. Assessments included DED severity (Ocular Surface Disease Index [OSDI], corneal staining, conjunctival staining, tear film break-up time [TFBUT], and Schirmer testing) and impression cytology of the conjunctiva with masked flow cytometry at baseline and at 30 days. Results There was a significant decrease in corneal staining (P<0.01), OSDI (P=0.02), and TFBUT (P<0.01) following treatment with PEG/PG + HP-Guar. Results from flow cytometry revealed a significant decrease in cells expressing HLA-DR (P=0.02). Conclusion Treatment with PEG/PG + HP-Guar eyedrops showed improvement in dry eye severity and reduction in surface inflammation as indicated by a reduction in HLA-DR expression. PMID:26170605

    A cohort study was conducted to assess the rate of follow-up visit within 30 days after hospital discharge and to determine factors associated with no follow-up among Thai HIV-infected adults during the period from November 2012 to October 2013. Of the 120 eligible patients, 76 (63%) were males, median age was 40 years, and 57 (48%) were newly diagnosed with HIV infection. The rate of follow-up within 30 days after hospital discharge was 69%. Independent factors associated with no follow-up were no caregiver (adjusted odds ratio [aOR] 7.82; p = 0.002), age (aOR 1.06; p = 0.007 for each year younger), being immigrant (aOR 5.10; p = 0.03) and monthly household income less than $US 300 (aOR 2.99; p = 0.04). These findings suggest the need for interventions to improve care engagement including close monitoring for follow-up, pre-discharge financial and medical coverage planning, assessment for the need for caregiver and patient education about the importance of care engagement.

    An unrestrained chimpanzee was studied in an isolation chamber and in his home cage environment. The study consisted of 49 urine collection days (14 days pre-, 5 days post- and 30 days of isolation), and then of 10 days in the home cage. Dietary intake, urine and fecal data were obtained. The effect of isolation on various excretory parameters was studied. Urine samples were analyzed for volume, osmolarity, creatinine, creatine, urea-N, 17-hydroxy corticosteroids, VMA, calcium and inorganic phosphorus. One way analyses of variance performed on the urinary excretion parameters showed all except creatinine excretion to vary significantly during periods of the study. The changes observed in calcium and phosphorus were highly significant. The data suggests that the calcium to phosphorus excretion ratio might serve as a physiological stress indicator of Selye's adaptation syndrome (period of resistance).

    Accurate risk stratification of patients undergoing total hip (THA) and knee (TKA) arthroplasty is essential in the highly scrutinized world of pay-for-performance, value-driven healthcare. We assessed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) surgical risk calculator's ability to predict 30-day complications using 1066 publicly-reported Medicare patients undergoing primary THA or TKA. Risk estimates were significantly associated with complications in the categories of any complication (P = .005), cardiac complication (P < .001), pneumonia (P < .001) and discharge to skilled nursing facility (P < .001). However, predictability of complication occurrence was poor for all complications assessed. To facilitate the equitable provision and reimbursement of patient care, further research is needed to develop accurate risk stratification tools in TKA and THA surgery. PMID:26165953

  17. Hip Fractures: What Information Does the Evidence Show That Patients and Families Need to Decrease 30-Day Readmission?

    2015-01-01

    The current bundled payment reimbursement from the Centers for Medicare & Medicaid Services will not cover the additional cost of hospital readmission for the same diagnosis, and patients with hip fractures have one of the highest cost-saving opportunities when compared with other admission reasons. Common reasons for readmission to the hospital after hip fracture include pneumonia, dehydration, and mobility issues. The learning modalities including visual, aural, read/write, and kinesthetic were used to make recommendations on how the education can be incorporated into the instruction of patients with hip fractures and their families. These learning techniques can be used to develop education to decrease possibility of 30-day readmission after hip fracture. Nurses must focus their education to meet the needs of each individual patient, adapting to different types of adult learners to increase the health literacy of patients with hip fractures and their families.

    Background The purpose of this study was to evaluate the long-term in-vivo hemodynamics, gas transfer and biocompatibility of an integrated artificial pump-lung (APL) developed for ambulatory respiratory support. Methods The study was conducted in an ovine model by surgically placing the APL between the right atrium and pulmonary artery. Nine sheep were implanted. Heparin was infused as an anticoagulant. The device flow, gas transfer and plasma free hemoglobin (PFH) were measured daily. Hematological data, platelet activation and blood biochemistry were assessed twice a week. After 30 days, the sheep were euthanized for necropsy. The explanted devices were examined for gross thrombosis. Results Five sheep survived for 29 to 31 days and were electively terminated. Four sheep expired or were terminated early due to mechanical failure of IV lines or device. The APL devices in the five long-term animals were capable of delivering an oxygen transfer rate of 148±18 ml/min at a flow rate of 2.99±0.46 l/min with blood oxygen saturation of 96.7±1.3%. The device flow and oxygen transfer were stable over 30 days. The animals had normal end-organ functions except for surgery-related transient alteration in kidney function, liver function, and cell and tissue injury. There was no hemolysis. The device flow path and membrane surface were free of gross thrombus. Conclusions The APL exhibited the capability of providing respiratory support with excellent biocompatibility, long-term reliability and the potential for bridging to lung transplant. PMID:22115337

    A two-person-30-day controlled ecological life support system (CELSS) integrated test was carried out, and more than 30 kinds of trace harmful gases including formaldehyde, benzene, and ammonia were measured and analyzed dynamically. The results showed that the kinds and quantities of the trace harmful gases presented a continuously fluctuating state during the experimental period, but none of them exceed the spacecraft maximum allowable concentration (SMAC). The results of the Pre-Test (with two persons without plants for 3 days) and the Test (with two persons and four kinds of plants for 30 days) showed that there are some notable differences for the compositions of the trace harmful gases; the volatile organic compounds (VOCs) such as toluene, hexane, and acetamide were searched out in the Pre-Test, but were not found in the Test. Moreover, the concentrations of the trace harmful gases such as acetic benzene, formaldehyde, and ammonia decreased greatly in the Test more than those in the Pre-Test, which means that the plants can purify these gases efficiently. In addition, the VOCs such as carbon monoxide, cyclopentane, and dichloroethylene were checked out in the Test but none in the Pre-Test, which indicates that these materials might be from the crew's metabolites or those devices in the platform. Additionally, the ethylene released specially by plants accumulated in the later period and its concentration reached nearly ten times of 0.05 mg m(-3) (maximum allowed concentration for plant growth, which must have promoted the later withering of plants). We hoped that the work can play a referring function for controlling VOCs effectively so that future more CELSS integrating tests can be implemented smoothly with more crew, longer period, and higher closure.

    The aim of the study was to analyze some of the key markers regulating anabolic and catabolic processes in mouse m. longissimus dorsi, an important back muscle system for trunk stabilization, following 30-day spaceflight and 8-day recovery period. C57/black mice were divided into 3 groups: 1) Vivarium Control (n=7), 2) Flight (n=5), 3) Recovery (n=5). The experiment was carried out in accordance with the rules of biomedical ethics certified by the Russian Academy of Sciences Committee on Bioethics. Using Western-blotting analysis we determined the content of IRS-1, p-AMPK, MURF-1 and eEF2 in m. longissimus dorsi. The content of IRS-1 in mice m. longissimus dorsi after the 30-day flight did not differ from the control group, however, in the Recovery group IRS-1 level was 80% higher (p<0.05) as compared to Control. Phospho-AMPK content remained unchanged. In the Recovery group there was an increase of eEF2 by 75% compared to the Control (p<0.05). After spaceflight MuRF-1 content was increased more than 2 times compared to the control animals. Thus, our findings showed that the work of the IRS-1 - dependent signaling pathway is only active in the recovery period. The content of the ubiquitin-ligase MURF-1 that takes parts in degrading myosin heavy chain was increased after the spaceflight, however, after 8-day recovery period MURF-1 level did not exceed the control indicating normalization of protein degradation in m. longissimus dorsi. The work was supported by the program of basic research of RAS and Federal Space Program of Russia for the period of 2006-2015.

    Hyperkalemia occurs frequently in hospitalized patients and is of particular concern for those who have undergone surgery, with postoperative care provided by clinicians of many disciplines. This review describes the normal physiology and how multiple perioperative factors can disrupt potassium homeostasis and lead to severe elevations in plasma potassium concentration. The pathophysiologic basis of diverse causes of hyperkalemia was used to broadly classify etiologies into those with altered potassium distribution (e.g. increased potassium release from cells or other transcellular shifts), reduced urinary excretion (e.g. reduced sodium delivery, volume depletion, and hypoaldosteronism), or an exogenous potassium load (e.g. blood transfusions). Surgical conditions of particular concern involve: rhabdomyolysis from malpositioning, trauma or medications; bariatric surgery; vascular procedures with tissue ischemia; acidosis; hypovolemia; and volume or blood product resuscitation. Certain acute conditions and chronic co-morbidities present particular risk. These include chronic kidney disease, diabetes mellitus, many outpatient preoperative medications (e.g. beta blockers, salt substitutes), and inpatient agents (e.g. succinylcholine, hyperosmolar volume expanders). Clinicians need to be aware of these pathophysiologic mechanisms for developing perioperative hyperkalemia as many of the risks can be minimized or avoided. PMID:25698564

    Background: Hospital discharge planning has been hampered by the lack of predictive models. Objective: To develop predictive models for nonelective rehospitalization and postdischarge mortality suitable for use in commercially available electronic medical records (EMRs). Design: Retrospective cohort study using split validation. Setting: Integrated health care delivery system serving 3.9 million members. Participants: A total of 360,036 surviving adults who experienced 609,393 overnight hospitalizations at 21 hospitals between June 1, 2010 and December 31, 2013. Main Outcome Measure: A composite outcome (nonelective rehospitalization and/or death within 7 or 30 days of discharge). Results: Nonelective rehospitalization rates at 7 and 30 days were 5.8% and 12.4%; mortality rates were 1.3% and 3.7%; and composite outcome rates were 6.3% and 14.9%, respectively. Using data from a comprehensive EMR, we developed 4 models that can generate risk estimates for risk of the combined outcome within 7 or 30 days, either at the time of admission or at 8 am on the day of discharge. The best was the 30-day discharge day model, which had a c-statistic of 0.756 (95% confidence interval, 0.754–0.756) and a Nagelkerke pseudo-R2 of 0.174 (0.171–0.178) in the validation dataset. The most important predictors—a composite acute physiology score and end of life care directives—accounted for 54% of the predictive ability of the 30-day model. Incorporation of diagnoses (not reliably available for real-time use) did not improve model performance. Conclusions: It is possible to develop robust predictive models, suitable for use in real time with commercially available EMRs, for nonelective rehospitalization and postdischarge mortality.

    It is known that increased destruction of hem structures is accompanied by increase of the endogenous carbon monoxide excretion rate with respiration (VCO). Changes VCO preceded the observed changes in the blood composition [D’yachenko A. et al., 2010]. Changes in blood composition, i.e. rise of red blood cells content and reduction of reticulocytes content was detected after a 12-day orbital flight (OF) in mice C57BL/6 [Gridley D.et al., 2003]. The purpose of this study was to investigate the effect of 30-day OF on excretion of endogenous CO. The method and apparatus for simultaneous measurement of VCO, and O2 and CO2 exchange were developed. The research consisted of three parts: 1). Measurement of VCO in five C57BL/6 mice after 30-day OF on the Russian satellite BION M1. 2). Measurement of VCO in six C57BL/6 mice after 30-day ground-based experiment (GBE) with simulated flight telemetry environment of BION M1. 3). Measurement of VCO in seven C57BL/6 mice in vivarium The results: Mice weight after OF was 24.3+-3.3 (mean +-SD) with minimal weight 18.1 g, and maximal weight 29.9 g. Vivarium mice weight was 27.0+-1.8 g. KGE mice weight was 25.0+-1.3 g. Mice age in all three groups was the same. We measured and estimated VCO and total CO excretion (MCO) for two gas mixtures ventilated mouse camera: atmospheric CO-contained air and then CO-free air(30 min). The results showed that the average MCO allocated GBE and vivarium mice did not significantly differ. Average MCO in mice after OF was significantly higher then in vivarium group (T=-2,74; p=0.02). MCO after GBE was between the vivarium and OF groups. MCO in OF and KGE groups did not differ ( T=-1,93; p=0,085). Blood tests in mice after OF was not carried out, because the recovery after the OF was studied in this group. The largest excretion of CO was observed in a mouse N39 after the OF. The weight of this mouse was only 18.1 g, i.e. much less than mean weight. Increase of VCO in food-restricted animal is known

    Cardiovascular diseases remain the main cause of mortality and morbidity worldwide; primary prevention is a priority for physicians. Biomarkers are useful tools able to identify high-risk individuals, guide treatments, and determine prognosis. Our aim is to investigate Endogenous Ouabain (EO), an adrenal stress hormone with hemodynamic effects, as a valuable biomarker of heart failure. In a population of 845 patients undergoing elective cardiac surgery, we have investigated the relationships between EO and echocardiography parameters/plasmatic biomarker of cardiac function. EO was found to be correlated negatively with left ventricular EF (p = 0.001), positively with Cardiac End-Diastolic Diameter (p = 0.047), and positively with plasmatic NT-proBNP level (p = 0.02). Moreover, a different plasmatic EO level (both preoperative and postoperative) was found according to NYHA class (p = 0.013). All these results have been replicated on an independent cohort of patients (147 subjects from US). Finally, a higher EO level in the immediate postoperative time was indicative of a more severe cardiological condition and it was associated with increased perioperative mortality risk (p = 0.023 for 30-day morality). Our data suggest that preoperative and postoperative plasmatic EO level identifies patients with a more severe cardiovascular presentation at baseline. These patients have a higher risk of morbidity and mortality after cardiac surgery. PMID:26609532

    Objective To update previous systematic review of predictive models for 28-day or 30-day unplanned hospital readmissions. Design Systematic review. Setting/data source CINAHL, Embase, MEDLINE from 2011 to 2015. Participants All studies of 28-day and 30-day readmission predictive model. Outcome measures Characteristics of the included studies, performance of the identified predictive models and key predictive variables included in the models. Results Of 7310 records, a total of 60 studies with 73 unique predictive models met the inclusion criteria. The utilisation outcome of the models included all-cause readmissions, cardiovascular disease including pneumonia, medical conditions, surgical conditions and mental health condition-related readmissions. Overall, a wide-range C-statistic was reported in 56/60 studies (0.21–0.88). 11 of 13 predictive models for medical condition-related readmissions were found to have consistent moderate discrimination ability (C-statistic ≥0.7). Only two models were designed for the potentially preventable/avoidable readmissions and had C-statistic >0.8. The variables ‘comorbidities’, ‘length of stay’ and ‘previous admissions’ were frequently cited across 73 models. The variables ‘laboratory tests’ and ‘medication’ had more weight in the models for cardiovascular disease and medical condition-related readmissions. Conclusions The predictive models which focused on general medical condition-related unplanned hospital readmissions reported moderate discriminative ability. Two models for potentially preventable/avoidable readmissions showed high discriminative ability. This updated systematic review, however, found inconsistent performance across the included unique 73 risk predictive models. It is critical to define clearly the utilisation outcomes and the type of accessible data source before the selection of the predictive model. Rigorous validation of the predictive models with moderate-to-high discriminative

    To investigate mechanisms of hypogravity motor syndrome development the immunoexpression of heat shock proteins (Hsp27 and Hsp70), proteins of synaptic transmission (Synaptophysin and PSD95) and neuroprotective proteins (VEGF and Flt-1) in motoneurons of lumbar spinal cord in c57black/6 control mice (n=2) and after 30-days space flight (n=2) was studied. For a quantitative assessment of target proteins level in motoneurons frozen cross sections of lumbar spinal cord were underwent to immunohistochemical staining. Primary antibodies against VEGF, Flt-1, Hsp27 and Hsp70 (SantaCruz Biotechnology, inc. USA), against Synaptophysin and PSD95 (Abcam plc, UK) were visualized by streptavidin-biotin method. Images of spinal cords were received using OlympusBX51WI microscope with AxioCamMRm camera (CarlZeiss, Germany) and the AxioVisionRel. 4.6.3 software (CarlZeiss, Germany). The digitized data were analyzed using ImageJ 1.43 software (NIH, the USA). Quantitively, protein level in motoneurons was estimated by the density of immunoprecipitation. Results of research have not revealed any reliable changes in the immunnoexpression of vascular endothelial growth factor (VEGF) and its Flt-1 receptor in motoneurons of lumbar spinal cord in control and in mice after 30-day space flight. Studying of heat shock proteins, such as Hsp27 and Hsp70, revealed the decrease in level of these proteins immunoexpression in motoneurons of mice from flight group by 15% and 10%, respectively. Some decrease in level of immunnoexpression of presynaptic membrane proteins (synaptophysin, by 21%) and proteins of postsynaptic area (PSD95, by 55%) was observed after space flight. The data obtained testify to possible changes in a functional state (synaptic activity and stress resistance) of motoneurons of lumbar spinal cord in mice after space flight. Thus, we obtained new data on involvement of motoneurons innervating skeletal muscles in development of hypogravity motor syndrome. Research was supported

    The results of studies that evaluated predictive factors for rebleeding in non-variceal upper gastrointestinal bleeding are inconsistent. The aim of this study was to investigate predictive factors for 30-day rebleeding in these patients. A consecutive 312 patients presenting symptoms and signs of gastrointestinal bleeding were enrolled in this prospective, observational study. Clinical and demographic characteristics and endoscopic findings were evaluated for potential factors associated with 30-day rebleeding using logistic regression analysis. Overall, 176 patients were included (male, 80.1%; mean age, 59.7±16.0 yr). Rebleeding within 7 and 30 days occurred in 21 (11.9%) and 27 (15.3%) patients, respectively. We found that chronic kidney disease (CKD) (OR, 10.29; 95% CI, 2.84-37.33; P<0.001), tachycardia (pulse>100 beats/min) during the admission (OR, 3.79; 95% CI, 1.25-11.49; P=0.019), and Forrest classes I, IIa, and IIb (OR, 6.14; 95% CI, 1.36-27.66; P=0.018) were significant independent predictive factors for 30-day rebleeding. However, neither Rockall nor Blatchford scores showed statistically significant relationships with 30-day rebleeding in a multivariate analysis. CKD, hemodynamic instability during hospitalization, and an endoscopic high-risk appearance are significantly independent predictors of 30-day rebleeding in patients with non-variceal upper gastrointestinal bleeding. These factors may be useful for clinical management of such patients. PMID:24133356

    Altered external mechanical loading during spaceflights causes negative effects on muscular and cardiovascular systems. The aim of the study was estimation of the cortical cytoskeleton statement of the skeletal muscle cells and cardiomyocytes. The state of the cortical cytoskeleton in C57BL6J mice soleus, tibialis anterior muscle fibers, and left ventricle cardiomyocytes was investigated after 30-day 2-g centrifugation ("2-g" group) and within 12 h after its completion ("2-g + 12-h" group). We used atomic force microscopy for estimating cell's transverse stiffness, Western blotting for measuring protein content, and RT-PCR for estimating their expression level. The transverse stiffness significantly decreased in cardiomyocytes (by 16%) and increased in skeletal muscles fibers (by 35% for soleus and by 29% for tibialis anterior muscle fibers) in animals of the 2-g group (compared with the control group). For cardiomyocytes, we found that, in the 2-g + 12-h group, α-actinin-1 content decreased in the membranous fraction (by 27%) and increased in cytoplasmic fraction (by 28%) of proteins (compared with the levels in the 2-g group). But for skeletal muscle fibers, similar changes were noted for α-actinin-4, but not for α-actinin-1. In conclusion, we showed that the different isoforms of α-actinins dissociate from cortical cytoskeleton under increased/decreased of mechanical load. PMID:25539936

    Transition from a normal gravitational environment to that of microgravity eventually results in decreased plasma and blood volumes, increasing with duration of exposure to microgravity. This loss of vascular fluid is presumably due to negative fluid and electrolyte balance and most likely contributes to the orthostatic intolerance associated with the return to gravity. The decrease in plasma volume is presumed to be a reflection of a concurrent decrease in extracellular fluid volume with maintenance of normal plasma-interstitial fluid balance. In addition, the specific alterations in renal function contributing to these changes in fluid and electrolyte homeostasis are potentially responding to neuro-humoral signals that are not consistent with systemic fluid volume status. We have previously demonstrated an early increase in both glomerular filtration rate and extracellular fluid volume and that this decreases towards control values by 7 days of simulated microgravity. However, longer duration studies relating these changes to plasma volume alterations and the response to return to orthostasis have not been fully addressed. Male Wistar rats were chronically cannulated, submitted to 30 days heat-down tilt (HDT) and followed for 7 days after return to orthostasis from HDT. Measurements of renal function and extracellular and blood volumes were performed in the awake rat.

    Functional imaging using positron emission tomography and later functional magnetic resonance imaging revealed a particular brainstem area that is believed to be specifically activated in migraine during, but not outside of the attack, and consequently has been coined the 'migraine generator'. However, the pathophysiological concept behind this term is not undisputed and typical migraine premonitory symptoms such as fatigue and yawning, but also a typical association of attacks to circadian and menstrual cycles, all make the hypothalamus a possible regulating region of migraine attacks. Neuroimaging studies investigating native human migraine attacks however are scarce and for methodological but also clinical reasons there are currently no studies investigating the last 24 h before headache onset. Here we report a migraine patient who had magnetic resonance imaging every day for 30 days, always in the morning, to cover, using functional imaging, a whole month and three complete, untreated migraine attacks. We found that hypothalamic activity as a response to trigeminal nociceptive stimulation is altered during the 24 h prior to pain onset, i.e. increases towards the next migraine attack. More importantly, the hypothalamus shows altered functional coupling with the spinal trigeminal nuclei and the region of the migraine generator, i.e. the dorsal rostral pons during the preictal day and the pain phase of native human migraine attacks. These data suggest that although the brainstem is highly linked to the migraine biology, the real driver of attacks might be the functional changes in hypothalamo-brainstem connectivity.

    Understanding performance factors for future planetary missions is critical for ensuring safe and successful planetary extra-vehicular activities (EVAs). The goal of this study was to gain operational knowledge of analog EVAs and develop biometric profiles for specific EVA types. Data was collected for a 120 and 30 day analog planetary exploration simulation focusing on EVA type, pre and post EVA conditions, and performance ratings. From this five main types of EVAs were performed: maintenance, science, survey/exploratory, public relations, and emergency. Each EVA type has unique characteristics and performance ratings showing specific factors in chronological components, environmental conditions, and EVA systems that have an impact on performance. Pre and post biometrics were collected to heart rate, blood pressure, and SpO2. Additional data about issues and specific EVA difficulties provide some EVA trends illustrating how tasks and suit comfort can negatively affect performance ratings. Performance decreases were noted for 1st quarter and 3rd quarter EVAs, survey/exploratory type EVAs, and EVAs requiring increased fine and gross motor function. Stress during the simulation is typically higher before the EVA and decreases once the crew has returned to the habitat. Stress also decreases as the simulation nears the end with the 3rd and 4th quarters showing a decrease in stress levels. Operational components and studies have numerous variable and components that effect overall performance, by increasing the knowledge available we may be able to better prepare future crews for the extreme environments and exploration of another planet.

    In vivo whole-body glucose utilization and uptake in multiple individual tissues were investigated in conscious 30-day-old Zucker rats, which when obese are hyperphagic, hyperinsulinemic, and normoglycemic. Whole-body glucose metabolism (assessed by (3-{sup 3}H)glucose) was 40% higher in obese (fa/fa) than in lean (Fa/fa) rats, suggesting that obese rats were quite responsive to their hyperinsulinemia. In obese compared with lean rats, tissue glucose uptake was increased by 15, 12, and 6 times in dorsal, inguinal, perigonadal white depots, respectively; multiplied by 2.5 in brown adipose tissue; increased by 50% in skin from inguinal region but not in that from cranial, thoracic, or dorsal area; and increased twofold in diaphragm but similar in heart in proximal intestine, and in total muscular mass of limbs. The data establish that in young obese rats the hypertrophied white adipose tissue was a major glucose-utilizing tissue whose capacity for glucose disposal compared with that of half the muscular mass. Adipose tissue could therefore play an important role in the homeostasis of glucose in obese rats in the face of their increased carbohydrate intake.

    An increasing number of studies have shown that circadian variation in the excretion of hormones, the sleep wake circle, the core body temperature rhythm, the tone of the autonomic nervous system and the activity rhythm are important both in health and in disease processes. An increasing attention has also been directed towards the circadian variation in endogenous rhythms in relation to surgery. The attention has been directed to the question whether the circadian variation in endogenous rhythms can affect postoperative recovery, morbidity and mortality. Based on the lack of studies where these endogenous rhythms have been investigated in relation to surgery we performed a series of studies exploring different endogenous rhythms and factors affecting these rhythms. We also wanted to examine whether the disturbances in the postoperative circadian rhythms could be correlated to postoperative recovery parameters, and if pharmacological administration of chronobiotics could improve postoperative recovery. Circadian rhythm disturbances were found in all the examined endogenous rhythms. A delay was found in the endogenous rhythm of plasma melatonin and excretion of the metabolite of melatonin (AMT6s) in urine the first night after both minor and major surgery. This delay after major surgery was correlated to the duration of surgery. The amplitude in the melatonin rhythm was unchanged the first night but increased in the second night after major surgery. The amplitude in AMT6s was reduced the first night after minimally invasive surgery. The core body temperature rhythm was disturbed after both major and minor surgery. There was a change in the sleep wake cycle with a significantly increased duration of REM-sleep in the day and evening time after major surgery compared with preoperatively. There was also a shift in the autonomic nervous balance after major surgery with a significantly increased number of myocardial ischaemic episodes during the nighttime period. The

    IMPORTANCE Current guidelines for delaying surgery after coronary stent placement are based on stent type. However, the indication for the stent may be an important risk factor for postoperative major adverse cardiac events (MACE). OBJECTIVE To determine whether the clinical indication for a coronary stent is associated with postoperative MACE. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study in patients at US Veterans Affairs hospitals who had a coronary stent placed between January 1,2000, and December 31, 2010, and underwent noncardiac surgery within the following 24 months. The association between the indication for stent and postoperative MACE rates was examined using logistic regression to control for patient and procedure factors. EXPOSURES Three subgroups of stent indication were examined: (1) myocardial infarction (MI); (2) unstable angina; and (3) revascularization not associated with acute coronary syndrome (non-ACS). MAIN OUTCOMES AND MEASURES Composite 30-day postoperative MACE rates including all-cause mortality, MI, or revascularization. RESULTS Among 26 661 patients (median [IQR] age, 68 [61.0–76.0] years; 98.4% male; 88.1% white) who underwent 41 815 surgical procedures within 24 months following coronary stent placement, the stent indication was MI in 32.8% of the procedures, unstable angina in 33.8%, and non-ACS in 33.4%. Postoperative MACE rates were significantly higher in the MI group (7.5%) compared with the unstable angina (2.7%) and non-ACS (2.6%) groups (P < .001). When surgery was performed within 3 months of percutaneous coronary intervention, adjusted odds of MACE were significantly higher in the MI group compared with the non-ACS group (odds ratio [OR] = 5.25; 95% CI, 4.08–6.75). This risk decreased over time, although it remained significantly higher at 12 to 24 months from percutaneous coronary intervention (OR = 1.95; 95% CI, 1.58–2.40). The adjusted odds of MACE for the unstable angina group were similar to those

    The extended-range (10-30-day) rainfall forecast over the entire China was carried out using spatial-temporal projection models (STPMs). Using a rotated empirical orthogonal function analysis of intraseasonal (10-80-day) rainfall anomalies, China is divided into ten sub-regions. Different predictability sources were selected for each of the ten regions. The forecast skills are ranked for each region. Based on temporal correlation coefficient (TCC) and Gerrity skill score, useful skills are found for most parts of China at a 20-25-day lead. The southern China and the mid-lower reaches of Yangtze River Valley show the highest predictive skills, whereas southwestern China and Huang-Huai region have the lowest predictive skills. By combining forecast results from ten regional STPMs, the TCC distribution of 8-year (2003-2010) independent forecast for the entire China is investigated. The combined forecast results from ten STPMs show significantly higher skills than the forecast with just one single STPM for the entire China. Independent forecast examples of summer rainfall anomalies around the period of Beijing Olympic Games in 2008 and Shanghai World Expo in 2010 are presented. The result shows that the current model is able to reproduce the gross pattern of the summer intraseasonal rainfall over China at a 20-day lead. The present study provides, for the first time, a guide on the statistical extended-range forecast of summer rainfall anomalies for the entire China. It is anticipated that the ideas and methods proposed here will facilitate the extended-range forecast in China.

    Background Co-morbidity of primary lung cancer (LC) and heart disease (HD), both requiring surgical therapy, characterizes a high risk group of patients necessitating prompt diagnosis and treatment. The aim of this study is the review of available evidence guiding the management of these patients. Methods Postoperative outcome of patients operated for primary LC (first meta-analysis) and for both primary LC and HD co-morbidity (second meta-analysis), were studied. Parameters examined in both meta-analyses were thirty-day postoperative mortality, postoperative complications, three- and five-year survival probabilities. The last 36 years were reviewed by using the PubMed data base. Thirty-seven studies were qualified for both meta-analyses. Results The pooled 30-day mortality percentages (%) were 4.16% [95% confidence interval (CI): 2.68–5.95] (first meta-analysis) and 5.26% (95% CI: 3.47–7.62) (second meta-analysis). Higher percentages of squamous histology and lobectomy, were significantly associated with increased (P=0.001) and decreased (P<0.001) thirty-day postoperative mortality, respectively (first meta-analysis). The pooled percentages for postoperative complications were 34.32% (95% CI: 24.59–44.75) (first meta-analysis) and 45.59% (95% CI: 35.62–55.74) (second meta-analysis). Higher percentages of squamous histology (P=0.001), lobectomy (P=0.002) and p-T1 or p-T2 (P=0.034) were associated with higher proportions of postoperative complications (second meta-analysis). The pooled three- and five- year survival probabilities were 68.25% (95% CI: 45.93–86.86) and 52.03% (95% CI: 34.71–69.11), respectively. Higher mean age (P=0.046) and percentage lobectomy (P=0.009) significantly reduced the five-year survival probability. Conclusions Lobectomy and age were both accompanied by reduced five-year survival rate. Also, combined aorto-coronary bypass grafting (CABG) with lobectomy for squamous pT1 or pT2 LC displayed a higher risk of postoperative

    Introduction. Acute kidney injury (AKI) is a common occurrence in the intensive care unit (ICU). Studies have looked at outcomes of renal replacement therapy using intermittent haemodialysis (IHD) in ICUs with varying results. Little is known about the outcomes of using IHD in resource-limited settings where continuous renal replacement therapy (CRRT) is limited. We sought to determine outcomes of IHD among critically ill patients admitted to a low-income country ICU. Methods. A retrospective review of patient records was conducted. Patients admitted to the ICU who underwent IHD for AKI were included in the study. Patients' demographic and clinical characteristics, cause of AKI, laboratory parameters, haemodialysis characteristics, and survival were interpreted and analyzed. Primary outcome was mortality. Results. Of 62 patients, 40 had complete records. Median age of patients was 38.5 years. Etiologic diagnoses associated with AKI included sepsis, malaria, and ARDS. Mortality was 52.5%. APACHE II (OR 4.550; 95% CI 1.2–17.5, p = 0.028), mechanical ventilation (OR 13.063; 95% CI 2.3–72, p = 0.003), and need for vasopressors (OR 16.8; 95% CI 3.4–82.6, p = 0.001) had statistically significant association with mortality. Conclusion. IHD may be a feasible alternative for RRT in critically ill haemodynamically stable patients in low resource settings where CRRT may not be available. PMID:27042657

    Background Existing publicly-reported readmission measures are condition-specific, representing < 20% of adult hospitalizations. An all-condition measure may better measure quality and promote innovation. Objective To develop an all-condition, hospital-wide readmission measure. Design Measure development Setting 4,821 US hospitals. Patients Medicare Fee for Service (FFS) beneficiaries ≥ 65 years. Measurements Hospital-level, risk-standardized unplanned readmissions within 30 days of discharge. The measure uses Medicare FFS claims and is a composite of five specialty-based risk-standardized rates for medicine, surgery/gynecology, cardiorespiratory, cardiovascular and neurology cohorts. We randomly split the 2007–2008 admissions for development and validation. Models were adjusted for age, principal diagnosis and comorbidity. We examined calibration in Medicare and all-payer data, and compared hospital rankings in the development and validation samples. Results The development dataset contained 8,018,949 admissions associated with 1,276,165 unplanned readmissions (15.9%). The median hospital risk-standardized unplanned readmission rate was 15.8 (range 11.6–21.9). The five specialty cohort models accurately predicted readmission risk in both Medicare and all-payer datasets for average risk patients but slightly overestimated readmission risk at the extremes. Overall hospital risk-standardized readmission rates did not differ statistically in the split samples (p=0.7 for difference in rank) and 76% of hospitals’ validation set rankings were within two deciles of the development rank (24% >2 deciles). Of hospitals ranking in the top or bottom deciles, 90% remained within two deciles (10% >2 deciles), and 82% remained within one decile (18% > 1 decile). Limitations Risk-adjustment was limited to that available in claims data. Conclusions We developed a claims-based hospital-wide unplanned readmission measure for profiling hospitals that produced reasonably

  19. Using multiple household food inventories to measure food availability in the home over 30 days: a pilot study

    PubMed Central

    2010-01-01

    Background The consumption of foods, especially by children, may be determined by the types of foods that are available in the home. Because most studies use a single point of data collection to determine the types of foods in the home, which can miss the change in availability when resources are not available, the primary objective of this study was to determine the extent to which the weekly availability of household food items changed over one month by 1) developing the methodology for the direct observation of the presence and amount of food items in the home; 2) conducting five in-home household food inventories over a thirty-day period in a small convenience sample; and 3) determining the frequency that food items were present in the participating households. Methods After the development and pre-testing of the 251-item home observation guide that used direct observation to determine the presence and amount of food items in the home (refrigerator, freezer, pantry, elsewhere), two trained researchers recruited a convenience sample of 9 households (44.4% minority); administered a baseline questionnaire (personal info, shopping habits, food resources, and food security); and conducted 5 in-home assessments (7-day interval) over a 30-day period. Each in-home assessment included food-related activities since the last assessment, and an observational survey of types and amounts of foods present. Results Complete data were collected from all 9 women (32.8 y ± 6.0; 3 married; 4 ± 1.6 adults/children in household; 4 received food assistance; and 6 had very low food security) and their households. Weekly grocery purchases (place, amount, and purpose) varied from once (n = 1) to every week (n = 5); 4 used fast food 2-3 times/wk for 4 weeks. The weekly presence and amounts of fresh and processed fruits and vegetables and dairy varied. Conclusions The feasibility of conducting multiple in-home assessments was confirmed with 100% retention of participants through 5 in

    Objectives Identifying patients at risk of a 30-day readmission can help providers design interventions, and provide targeted care to improve clinical effectiveness. This study developed a risk model to predict a 30-day inpatient hospital readmission for patients in Maine, across all payers, all diseases and all demographic groups. Methods Our objective was to develop a model to determine the risk for inpatient hospital readmission within 30 days post discharge. All patients within the Maine Health Information Exchange (HIE) system were included. The model was retrospectively developed on inpatient encounters between January 1, 2012 to December 31, 2012 from 24 randomly chosen hospitals, and then prospectively validated on inpatient encounters from January 1, 2013 to December 31, 2013 using all HIE patients. Results A risk assessment tool partitioned the entire HIE population into subgroups that corresponded to probability of hospital readmission as determined by a corresponding positive predictive value (PPV). An overall model c-statistic of 0.72 was achieved. The total 30-day readmission rates in low (score of 0–30), intermediate (score of 30–70) and high (score of 70–100) risk groupings were 8.67%, 24.10% and 74.10%, respectively. A time to event analysis revealed the higher risk groups readmitted to a hospital earlier than the lower risk groups. Six high-risk patient subgroup patterns were revealed through unsupervised clustering. Our model was successfully integrated into the statewide HIE to identify patient readmission risk upon admission and daily during hospitalization or for 30 days subsequently, providing daily risk score updates. Conclusions The risk model was validated as an effective tool for predicting 30-day readmissions for patients across all payer, disease and demographic groups within the Maine HIE. Exposing the key clinical, demographic and utilization profiles driving each patient’s risk of readmission score may be useful to providers

    The incidence of postoperative hemorrhage following thyroid surgery stands at 1%-2 %. This low incidence contrasts with the significant potential complications of postoperative hemorrhage. Influencing factors and measures mentioned in the literature and own studies are discussed. Although an improvement in the postoperative hemorrhage rate was to be expected indirectly due to the increasing use of coagulation-relevant medication, there has been neither an increase in incidence nor a reduction in resultant complications, including primarily recurrent vocal cord paresis, tracheotomy and mortality. Factors that influence surgical success include a meticulous technique and caution, as well as ensuring intensive and qualified postoperative monitoring for a minimum of 4-6 h, thereby permitting immediate revision surgery at any time.

    The incidence of peripartum disorders in dairy herds negatively influences productivity and reproductive performance. Concrete data from local areas are helpful for explaining the importance of peripartum management to dairy farmers. This study was conducted to clarify the association of culling and death rate within 30 days after calving with productivity or reproductive performance in 179 dairy herds in Fukuoka, Southern Japan. A database was compiled from the records of the Livestock Improvement Association of Japan, the Dairy Cooperative Association and the Federation of Agricultural Mutual Relief Association. In this study, we created a comprehensive database of dairy farm production data for epidemiological analysis and used a general linear mixed model to analyze the association of culling and death rate within 30 days after calving with milk production or reproductive performance. The database can be used to describe, analyze and predict the risk of production. A cross-sectional analysis with contrasts was applied to investigate the association of cows served by AI/all cows, pregnant cows/cows served by AI, days open, milk yield and somatic cell counts with culling and death rate within 30 days after calving. The days open value significantly increased with increasing rate of culling and death within 30 days after calving (P for trend <0.001). No significant differences were found for the other comparisons. Our data suggest that proper feeding and management in the dry period may lead to improved postpartum reproductive performance in this dairy cow cohort. PMID:26666177

    Of the 1.5 million people diagnosed with pleural effusion in the USA annually, ~178 000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied.This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The aetiology of the effusions was determined using standardised criteria. Mortality was determined at 30 days and 1 year.247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1-year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign aetiologies (29% and 55%), congestive heart failure (22% and 53%), and renal failure (14% and 57%, respectively). Patients with bilateral, relative to unilateral, pleural effusion were associated with higher risk of death at 30 days and 1 year (17% versus 47% (hazard ratio (HR) 2.58, 95% CI 1.44-4.63) and 36% versus 69% (HR 2.32, 95% CI 1.55-3.48), respectively).Patients undergoing thoracentesis for pleural effusion have high short- and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign aetiologies, congestive heart failure and renal failure. Bilateral pleural effusion is distinctly associated with high mortality. PMID:25837039

    Mechanical ventilation support for acute respiratory distress syndrome (ARDS) patients involves the use of low tidal volumes and positive end-expiratory pressure. Nevertheless, the optimal ventilator strategy for ARDS patients undergoing extracorporeal membrane oxygenation (ECMO) therapy remains unknown. A retrospective analysis of a consecutive series of adult ARDS patients treated with V-V ECMO from October 2012 to May 2015 was performed. Mechanical ventilation data, as well as demographic and clinical data, were collected. We assessed the association between ventilator data and outcomes of interest. The primary outcome was hospital survival. Secondary outcome was 30 day survival posthospital discharge. Sixty-four ARDS patients were treated with ECMO. Univariate analysis showed that plateau pressure was independently associated with hospital survival. Tidal volume, positive end-expiratory pressure (PEEP), and plateau were independently associated with 30 day survival. Multivariate analysis, after controlling for covariates, revealed that a 1 unit increase in plateau pressure was associated with a 21% decrease in the odds of hospital survival (95% confidence interval [CI] = 6.39-33.42%, p = 0.007). In regards to 30 day survival postdischarge, a 1 unit increase in plateau pressure was associated with a 14.4% decrease in the odds of achieving the aforementioned outcome (95% CI = 1.75-25.4%, p = 0.027). Also, a 1 unit increase in PEEP was associated with a 36.2% decrease in the odds of 30 day survival (95% CI = 10.8-54.4%, p = 0.009). Among ARDS patients undergoing ECMO therapy, only plateau pressure is associated with hospital survival. Plateau pressure and PEEP are both associated with 30 day survival posthospital discharge.

    There is wide variation in the management of emergency department (ED) patients with atrial fibrillation (AF). We aimed to derive and internally validate the first prospective, ED-based clinical decision aid to identify patients with AF at low risk for 30-day adverse events. We performed a prospective cohort study at a university-affiliated, tertiary-care, ED. Patients were enrolled from June 9, 2010 to February 28, 2013 and followed for 30 days. We enrolled a convenience sample of ED patients presenting with symptomatic AF. Candidate predictors were based on ED data available in the first two hours. The decision aid was derived using model approximation (preconditioning) followed by strong bootstrap internal validation. We utilized an ordinal outcome hierarchy defined as the incidence of the most severe adverse event within 30 days of the ED evaluation. Of 497 patients enrolled, stroke and AF-related death occurred in 13 (3%) and 4 (<1%) patients, respectively. The decision aid included the following: age, triage vitals (systolic blood pressure, temperature, respiratory rate, oxygen saturation, supplemental oxygen requirement); medical history (heart failure, home sotalol use, prior percutaneous coronary intervention, electrical cardioversion, cardiac ablation, frequency of AF symptoms); ED data (2 hour heart rate, chest radiograph results, hemoglobin, creatinine, and brain natriuretic peptide). The decision aid’s c-statistic in predicting any 30-day adverse event was 0.7 (95% CI, 0.65, 0.76). In conclusion, among ED patients with AF, AFFORD provides the first evidence based decision aid for identifying patients who are at low risk for 30-day adverse events and candidates for safe discharge.

    The presence of anaerobes in the blood stream is known to be associated with a higher rate of mortality. However, few prognostic risk factor analyses examining whether a patient's background characteristics are associated with the prognosis have been reported. We performed a retrospective case-controlled study to assess the prognostic factors associated with death from anaerobic bacteremia. Seventy-four patients with anaerobic bacteremia were treated between January 2005 and December 2014 at Aichi Medical University Hospital. The clinical information included drug susceptibility was used for analysis of prognostic factors for 30-day mortality. Multivariate logistic analyses revealed an association between the 30-day mortality rate and malignancy (OR: 3.64, 95% CI: 1.08-12.31) and clindamycin resistance (OR: 7.93, 95% CI: 2.33-27.94). The result of Kaplan-Meier analysis of mortality showed that the 30-day survival rate was 83% in clindamycin susceptible and 38.1% in clindamycin resistant anaerobes causing bacteremia. The result of log-rank test also showed that susceptibility to clindamycin affected mortality (P < 0.001). Our results indicated that malignancy and clindamycin susceptibility could be used to identify subgroups of patients with anaerobic bacteremia with a higher risk of 30-day mortality. The results of this study are important for the early and appropriate management of patients with anaerobic bacteremia. PMID:26903282

    Objective Nearly 70% of emergency departments (ED) visits for atrial fibrillation (AF) result in hospitalization. The incidence of serious 30-day adverse events following an ED evaluation for AF remains low. This study’s goal was to prospectively validate our previously reported Risk Estimator Decision aid for AF (RED-AF) model for estimating a patient’s risk of experiencing a 30-day adverse event. Methods This was a prospective cohort study, which enrolled a convenience sample of ED patients presenting with AF. RED-AF, previously derived from a retrospective cohort of 832 patients, assigns points based on age, sex, coexisting disease (heart failure, hypertension, chronic obstructive pulmonary disease), smoking, home medications (beta blocker, diuretic), physical examination findings (dyspnea, palpitations, peripheral edema), and adequacy of ED ventricular rate control. Primary outcome was occurrence of ≥1 AF-related adverse outcome (ED visits, rehospitalization, cardiovascular complications, death) within 30 days. We identified a clinically relevant threshold and measured RED-AF’s performance in this prospective cohort, assessing its calibration, discrimination, and diagnostic accuracy. Results The study enrolled 497 patients between June 2010 and February 2013. Of these, 120 (24%) had ≥1 adverse event within 30 days. A RED-AF score of 87 was identified as an optimal threshold, resulting in sensitivity (95% CI) and specificity (95%CI) of 96% (91–98) and 19% (15–23), respectively. Positive and negative predictive values were 27% (23–32) and 93% (85–97), respectively. The c-statistic for RED-AF was 0.65 (95% CI, 0.59 to 0.71). Conclusion In this separate validation cohort, RED-AF performed moderately well and similar to the original derivation cohort for identifying the risk of short-term AF-related adverse events in ED patients diagnosed with AF.

    Co-morbidities have typically been considered as prevalent cardiovascular risk factors and cardiovascular diseases rather than systematic measures of general co-morbidity burden in patients who underwent percutaneous coronary intervention (PCI). Charlson co-morbidity index (CCI) is a measure of co-morbidity burden providing a means of quantifying the prognostic impact of 22 co-morbid conditions on the basis of their number and prognostic impact. The study evaluated the impact of the CCI on cardiac mortality and major adverse cardiovascular events (MACE) after PCI through analysis of the Nobori-2 study. The prognostic impact of CCI was studied in 3,067 patients who underwent PCI in 4,479 lesions across 125 centers worldwide on 30-day and 1- and 5-year cardiac mortality and MACE. Data were adjusted for potential confounders using stepwise logistic regression; 2,280 of 3,067 patients (74.4%) had ≥1 co-morbid conditions. CCI (per unit increase) was independently associated with an increase in both cardiac death (odds ratio [OR] 1.47 95% confidence interval [CI] 1.20 to 1.80, p = 0.0002) and MACE (OR 1.29 95% CI 1.14 to 1.47, p ≤0.0011) at 30 days, with similar observations recorded at 1 and 5 years. CCI score ≥2 was independently associated with increased 30-day cardiac death (OR 4.25, 95% CI 1.24 to 14.56, p = 0.02) at 1 month, and this increased risk was also observed at 1 and 5 years. In conclusion, co-morbid burden, as measured using CCI, is an independent predictor of adverse outcomes in the short, medium, and long term. Co-morbidity should be considered in the decision-making process when counseling patients regarding the periprocedural risks associated with PCI, in conjunction with traditional risk factors.

    Background Primary spontaneous pneumothorax (PSP) is a relatively common disorder in young patients. Although various surgical techniques have been introduced, recurrence after video-assisted thoracoscopic surgery (VATS) remains high. The aim of study was to identify the risk factors for postoperative recurrence after thoracoscopic bullectomy in the spontaneous pneumothorax. Methods From January 2011 through March 2013, two hundreds and thirty two patients underwent surgery because of pneumothorax. Patients with a secondary pneumothorax, as well as cases of single port surgery, an open procedure, additional pleural procedure (pleurectomy, pleural abrasion) or lack of medical records were excluded. The records of 147 patients with PSP undergoing 3-port video-assisted thoracoscopic bullectomy with staple line coverage using an absorbable polyglycolic acid (PGA) sheet were retrospectively reviewed. Results The median age was 19 years (range, 11−34 years) with male predominance (87.8%). Median postoperative hospital stay was 3 days (range, 1−10 days) without mortality. Complications were developed in five patients. A total of 24 patients showed postoperative recurrence (16.3%). Younger age less than 17 years old and immediate postoperative air leakage were risk factors for postoperative recurrence after thoracoscopic bullectomy by multivariate analysis. Conclusions Immediate postoperative air leakage was the risk factor for postoperative recurrence. However, further study will be required for the correlation of air leakage with recurrence.

    Elderly surgical patients frequently experience postoperative delirium (POD) and the subsequent development of postoperative cognitive dysfunction (POCD). Clinical features include deterioration in cognition, disturbance in attention and reduced awareness of the environment and result in higher morbidity, mortality and greater utilization of social financial assistance. The aging Western societies can expect an increase in the incidence of POD and POCD. The underlying pathophysiological mechanisms have been studied on the molecular level albeit with unsatisfying small research efforts given their societal burden. Here, we review the known physiological and immunological changes and genetic risk factors, identify candidates for further studies and integrate the information into a draft network for exploration on a systems level. The pathogenesis of these postoperative cognitive impairments is multifactorial; application of integrated systems biology has the potential to reconstruct the underlying network of molecular mechanisms and help in the identification of prognostic and diagnostic biomarkers.

    To define the factors associated with 30-day mortality among adult patients with invasive pneumococcal disease (IPD), we conducted a retrospective review of all cases of IPD in Alberta from 2000 to 2004. We hypothesized that multiple factors would be predictive of such mortality. We also examined the factors predictive of early (within 5 days of admission) mortality. We identified 1154 patients who met our inclusion criteria, 163 (14.1%) of whom died within 30 days. Over half (62.6%) of the deaths occurred within 5 days of admission. Ten factors were independently associated with increased 30-day mortality: 3 comorbidity factors-cancer within 5 years of diagnosis of IPD, diabetes, and cirrhosis; 4 complications-requirement for supplemental oxygen, mechanical ventilation, alteration of mental status, and cardiac arrest; 2 microorganism-related factors-infection with high- or infection with intermediate-mortality serotypes; and 1 treatment-related factor-treatment with a single antibiotic. Age 18-40 years and treatment with 2 antibiotics concurrently were associated with lower 30-day mortality. Comorbid illnesses were not contributory to early mortality (within 5 days of admission); instead, complications (alteration of mental status, requirement for supplemental oxygen, mechanical ventilation, and cardiac arrest) as well as infection with high-mortality serotypes and treatment with a single antibiotic were important. Age 18-40 years, infection with serotypes in the polysaccharide vaccine, and treatment with 2 or more than 2 antibiotics were associated with decreased early mortality. Early mortality accounted for 62.6% of the deaths. In conclusion, we found that mortality in IPD is multifactorial, the factors differ for 5- and 30-day mortality, and mortality is associated with host (age and complications), microorganism (pneumococcal serotypes), and therapeutic factors. Our data indicate that treatment with 2 or more antibiotics effective against Streptococcus

    Objective To report on the rate of 30-day readmission and the rate of additional or revision surgery within 12 months following total ankle replacement (TAR). Design A data-linkage study of the UK National Joint Registry (NJR) data and Hospital Episodes Statistics (HES) database. These two databases were linked in a deterministic fashion. HES episodes 12 months following the index procedure were isolated and analysed. Logistic regression was used to model predictors of reoperation and revision for primary ankle replacement. Participants All patients who underwent primary and revision ankle replacements according to the NJR between February 2008 and February 2013. Results The rate of 30-day readmission following primary and revision ankle replacement was 2.2% and 1.3%, respectively. In the 12 months following primary and revision ankle replacements, the revision rate (where implants needed to be removed) was 1.2% with increased odds in those orthopaedic units preforming <20 ankle replacements per year and patients with a preoperative fixed equinus deformity. The reoperation other than revision (where implants were not removed) in the 12 months following primary and revision TARs was 6.6% and 9.3%, respectively. Rheumatoid arthritis, cemented prosthesis and high ASA grade significantly increased the odds of reoperation. Conclusions TAR has a 30-day readmission rate of 2.2%, which is similar to that of knee replacement but lower than that of total hip replacement. 6.6% of patients undergoing primary TAR require a reoperation within 12 months of the index procedure. Early revision rates are significantly higher in low-volume centres. PMID:27217286

    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

    A 30 day hypokinesia in rabbits led to a considerable lag in weight gain for the skeletal bones, reduction in Ca45 uptake, and an increase in isotope resorption rate in the rapidly metabolized fraction of extremity bones. On the other hand, Ca45 content in the teeth and maxillae increased, which may be explained by redistribution of isotope among the various mineralized tissues. Injection of thyrocalcitonin (50 IU/day) produced a distinct normalizing effect on Ca45 uptake and resorption in the mineralized tissues of rabbits kept hypokinetic.

    Although the long-term results following traditional total joint arthroplasty are excellent, postoperative pain management has been suboptimal. Under-treatment of pain is a focus of growing concern to the orthopedic community. Poorly controlled postoperative pain leads to undesirable outcomes, including immobility, stiffness, myocardial ischemia, atelectasis, pneumonia, deep venous thrombosis, anxiety, depression, and chronic pain. Over the past decade, the attempt to minimize postoperative complications, combined with the move toward minimally invasive surgery and early postoperative mobilization, has made pain management a critical aspect of joint replacement surgery. Effective protocols are currently available; all include a multimodal approach. Debate continues regarding the ideal approach; however, reliance on narcotic analgesia alone is suboptimal.

    Aim To assess the seven-year trends of hospitalization incidence due to acute peptic ulcer hemorrhage (APUH) and associated risk factors, and examine the differences in these trends between two regions in Croatia. Methods The study collected sociodemographic, clinical, and endoscopic data on 2204 patients with endoscopically confirmed APUH who were admitted to the Clinical Hospital Center “Sestre Milosrdnice,” Zagreb and Clinical Hospital Center Split between January 1, 2005 and December 31, 2011. We determined hospitalization incidence rates, 30-day case fatality rate, clinical outcomes, and incidence-associated factors. Results No differences were observed in APUH hospitalization incidence rates between the regions. Age-standardized one-year cumulative APUH hospitalization incidence rate calculated using the European Standard Population was significantly higher in Zagreb than in Split region (43.2/100 000 vs 29.2/100,000). A significantly higher APUH hospitalization incidence rates were observed in the above 65 years age group. Overall 30-day case fatality rate was 4.9%. Conclusion The hospitalization incidence of APUH in two populations did not change over the observational period and it was significantly higher in the Zagreb region. The incidence of acute duodenal ulcer hemorrhage also remained unchanged, whereas the incidence of acute gastric ulcer hemorrhage increased. The results of this study allow us to monitor epidemiological indicators of APUH and compare data with other countries. PMID:25559836

    In order to study nickel ion release associated with nickel allergy, Cu-18Ni-20Zn nickel-silver alloy was immersed in artificial sweat and Ringer physiological solution for 30 days. Dissolution of metal ions was measured as a function of time, and the characteristics of the solid surface layer formed after 30 days were studied by SEM/EDS and XPS. The dissolution of nickel prevails over dissolution of copper and zinc. Nickel release in artificial sweat is approximately 10 times higher than in Ringer physiological solution and in both solutions the nickel release exceeds 0.5 μg cm -2 week -1, the threshold above which the allergy is triggered. Evidence of selective nickel dissolution is reported. The composition of the surface layer formed in artificial sweat and in Ringer physiological solution differs in the content of nickel and chlorine. In artificial sweat, the major constituents of the surface layer are dominantly oxides, Cu 2O and ZnO, with traces of chlorine. In Ringer physiological solution, the composition of the surface layer changes to a mixture of oxides, chlorides and/or oxychlorides. Two components peaks were detected in the Cl 2p 3/2 peak; however, it was not possible to distinguish the exact nature of the chloride compound formed. The mechanism of nickel release is discussed as a function of the composition of the solution.

    Study Objectives: Evaluate the efficacy of a novel device placed in the nares that imposes an expiratory resistance for the treatment of obstructive sleep apnea (OSA) and evaluate adherence to the device over a 30-day in-home trial period. Design: One diagnostic and 3 treatment polysomnograms were administered in a Latin-square design to identify the optimal expiratory resistance to be used during the 30-day in-home trial. Subjects had repeat polysomnography with the prescribed device at the end of the 30-day trial. Setting: Multicenter study. Participants: Participants (N = 34; age 27 to 67) with a baseline apnea-hypopnea index (AHI) ≥ 5. Measurements and Results: The AHI was reduced from 24.5 ± 23.6 (mean ± SD) to an average of 13.5 ± 18.7 (p < 0.001) across initial treatment nights. The AHI was 15.5 ± 18.9 (p = 0.001) for the prescribed device at the end of the 30-day trial. Of 24 subjects with an AHI > 10 at baseline, 13 achieved an AHI ≤ 10 on the initial treatment nights; 10 had a similar response on the final treatment night. Percent of the night snoring decreased from 27.5 ± 23.2 to 11.6 ± 13.7 (p < 0.001) on initial treatment nights and 14.6 ± 20.6 (p = 0.013) at the end of the trial; Epworth Sleepiness scores decreased from 8.7 ± 4.0 at baseline to 6.9 ± 4.4 (p < 0.001) at the end of the trial; the Pittsburgh Sleep Quality Index improved from 7.4 ± 3.3 to 6.5 ± 3.6 (p = 0.042). Mean oxygen saturation increased from 94.8 ± 2.0 to 95.2 ± 1.9 (p = 0.023) on initial treatment nights and 95.3 ± 1.9 (p = 0.003) at the end of the trial. Sleep architecture was not affected. Participants reported using the device all night long for 94% of nights during the in-home trial. Conclusions: Treatment with this novel device was well tolerated and accepted by the participants. An overall reduction in AHI was documented; however, therapeutic response was variable among the participants. Further research is required to identify the ideal candidates for this

    Nine-hundred twenty-one community-dwelling patients 65 years of age or older, who sustained an operatively treated hip fracture from July 1, 1987 to June 30, 1998 were followed up for the development of postoperative delirium. The outcomes examined in the current study were postoperative complication rates, in-hospital mortality, hospital length of stay, hospital discharge status, 1-year mortality rate, place of residence, recovery of ambulatory ability, and activities of daily living 1 year after surgery. Forty-seven (5.1%) patients were diagnosed with postoperative delirium. Patients who had delirium develop were more likely to be male, have a history of mild dementia, and have had surgery under general anesthesia. Patients who had postoperative delirium develop had a significantly longer length of hospitalization. They also had significantly higher rates of mortality at 1 year, were less likely to recover their prefracture level of ambulation, and were more likely to show a decline in level of independence in basic activities of daily living at the 1-year followup. There was no difference in the rate of postoperative complications, in-hospital mortality, discharge residence, and recovery of instrumental activities of daily living at 1 year. PMID:15187857

    Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of postoperative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication. PMID:26605028

    Invasive pneumococcal disease (IPD), caused by infection with Streptococcus pneumoniae, has a substantial global burden. There are over 90 known serotypes of S. pneumoniae with a considerable body of evidence supporting serotype-specific mortality rates immediately following IPD. This is the first study to consider the association between serotype and longer-term mortality following IPD. Using enhanced surveillance data from the North East of England we assessed both the short-term (30-day) and longer-term (⩽7 years) independent adjusted associations between individual serotypes and mortality following IPD diagnosis using logistic regression and extended Cox proportional hazards models. Of the 1316 cases included in the analysis, 243 [18·5%, 95% confidence interval (CI) 16·4-20·7] died within 30 days of diagnosis. Four serotypes (3, 6A, 9N, 19 F) were significantly associated with overall increased 30-day mortality. Effects were observable only for older adults (⩾60 years). After extension of the window to 12 months and 36 months, one serotype was associated with significantly increased mortality at 12 months (19 F), but no individual serotypes were associated with increased mortality at 36 months. Two serotypes had statistically significant hazard ratios (HR) for longer-term mortality: serotype 1 for reduced mortality (HR 0·51, 95% CI 0·30-0·86) and serotype 9N for increased mortality (HR 2·30, 95% CI 1·29-4·37). The association with serotype 9N was no longer observed after limiting survival analysis to an observation period starting 30 days after diagnosis. This study supports the evidence for associations between serotype and short-term (30-day) mortality following IPD and provides the first evidence for the existence of statistically significant associations between individual serotypes and longer-term variation in mortality following IPD.

    It was shown that changes in structural and metabolic indices of extensor muscles of the lower extremities were usually found in man after exposure to space flight or to bed rest. Similar changes were also observed in monkeys, space-flown on "Kosmos" biosatellites. Response to weightlessness and to restraint was found to be different in m. soleus and in m. vastus lateralis. Therefore, it is important to study structural and metabolic changes of m. vastus lateralis fibers under conditions of gravitational unloading in monkeys, who have motor apparatus similar to that of man, and are much more fruitful object of research. It is assumed that artificial gravity can serve as a countermeasure, aimed at diminishing effects of gravitational unloading. We have studied the effect of repeated gravity overloading, created by means of a centrifuge, on structural and metabolic indices of monkey m. vastus lateralis at the background of 30 day head down tilt bed rest (BR).

    The effect of transcutaneous electromyostimulation (EMS) on the development of atrophy and the loss of strength in lower limb musculature in humans exposed to microgravity was determined in three subjects who received EMS twice daily in a 3-d on/1-d off cycle on their dominant leg during 30 days of bedrest. The output waveform from the stimulator was sequenced to the knee extensors, knee flexors, ankle extensors, and ankle flexors, and caused three isometric contractions of each muscle group per minute. It was found that, in the dominant leg, EMS acted to attenuate the changes caused by bedrest, such as reductions in the leg volume, muscle compartment size, cross-sectional area of slow- and fast-twitch fibers, strength, and aerobic enzyme activities, and an increase in leg compliance.

    Mechanical unloading of muscle during spaceflight in microgravity is known to cause muscular atrophy, changes in muscle fiber type composition, gene expression, and reductions in regenerative muscle growth. Although limited data exists for long-term effects of microgravity in human muscle, these processes have mostly been studied in rodents for short periods of time, up to two weeks of spaceflight. Here we report on how 30-day, long-term, mechanical unloading in microgravity affects mouse muscle of the femoral Quadriceps group. To conduct these studies we used muscle tissue from 6 mice from the NASA Biospecimen Sharing Program conducted in collaboration with the Institute for Biomedical Problems of the Russian Academy of Sciences, during the Russian Bion M1 biosatellite mission in 2013. Muscle morphology observed in histological sections shows signs of extensive atrophy and regenerative hypoplasia. Specifically, we observed a two-fold decrease in the number of myonuclei and low density of myofibrils, their separation and fragmentation. Despite obvious atrophy, muscle regeneration nevertheless appears to have continued after 30 days in microgravity as evidenced by thin and short newly formed muscle fibers. Many of them however showed evidence of apoptosis and degradation of synthesized fibrils, suggesting long-term unloading in microgravity affects late stages of myofiber differentiation. Ground asynchronous and vivarium control animals showed normal, well-developed tissue structure with sufficient blood and nerve supply and evidence of regenerative formation of new muscle fibers free of apoptotic nuclei. Myofiber nuclei stress responses in spaceflight animals was detected by positive nuclear immunolocalization of c-jun and c-myc proteins. Regenerative activity of satellite cells in muscle was localized with pax-7, MyoD and MCad immunostaining, and did not appear altered in microgravity. In summary, long-term spaceflight in microgravity causes significant atrophy

    This study was to investigate the immunotoxicological potential of corn genetically modified (GM) with Bacillus thuringiensis (Bt) Cry1Ah gene in BALB/c mice. Female BALB/c mice were randomly assigned to one of the four groups: the negative control group, the parental corn group, the GM corn group and the positive control group with 10 mice per group. Mice in the GM corn group and the parental corn group were fed with diets containing 70% corresponding corn for 30 days. Mice in the negative control group and the positive control group were fed with AIN93G diet, administered with saline or 200 mg/kg of cyclophosphamide (CY) via intraperitoneal injection 24 h before the termination of the study, respectively. At the end of the study, the immunotoxicological effects of the GM corn were evaluated through immunopathology parameters including body and organ weights, hematology and clinical chemistry parameters, histological examination, peripheral blood lymphocytes phenotype; humoral immunity including antibody plaque-forming cell, serum immunoglobulin, cytokine and half hemolysis value; cellular immunity such as mitogen-induced splenocyte proliferation, cytotoxic T-lymphocyte reaction, delayed-type hypersensitivity reaction; non-specific immunity including phagocytic activities of phagocytes, natural killer cell activity. A single dose of cyclophosphamide (200 mg/kg bw) was found to have significant adverse effects on immunopathology, cellular immunity, and humoral immunity in mice. The corn genetically modified with Bt Cry1Ah gene is considered consistent with the parental corn in terms of immunopathology, humoral immunity, cellular immunity and non-specific immunity. No adverse immunotoxicological effects of GM corn with Bt Cry1Ah gene were found when feeding mice for 30 days. PMID:24520311

    Background Atrial fibrillation is the most common complication of cardiac surgery and is associated with significant morbidity and mortality. Recognizing patients at high risk for developing postoperative atrial fibrillation (POAF) may help identify those who could benefit from strategies to prevent POAF. This study was conducted to delineate outcomes and to assess risk factors for POAF among Taiwanese patients undergoing coronary artery bypass grafting (CABG). Methods From January 2009 until February 2012, this prospective study included 266 consecutive patients admitted to our hospital with coronary artery disease. All patients underwent isolated CABG. Patients with preoperative permanent atrial fibrillation and concomitant surgery were excluded. Multiple risk factors associated with the incidence of POAF were collected and evaluated. Results POAF occurred in 126 of 226 patients (47.37%). Univariate analysis revealed that significant risk factors for the condition were age, gender, diabetes, dyslipidemia, smoking, impaired renal function, impaired cardiac function, and increased serum electrolytes. Multivariate analysis showed dyslipidemia [hazard ratio (HR): 0.418; 95% confidence interval (Cl): 0.190-0.915, p = 0.029], impaired renal function as indicated by an estimated glomerular filtration rate < 60 mL/min/1.73 m2 (HR: 3.174; 95% CI: 1.432-7.037, p = 0.004), and serum sodium (HR: 1.112; 95% Cl: 1.047-1.182, p = 0.001) prior to cardiopulmonary bypass as significant. Moreover, POAF was associated with lower 30-day, 1- and 3-year cumulative survival rates and higher early postoperative complications. Conclusions Patients with isolated CABG who were administered β-blockers, angiotensin converting enzyme inhibitor/angiotensin receptor blockers treatment, and lipid therapy before CABG were associated with reduced POAF, while those with impaired renal function and higher serum sodium before CABG predisposed POAF in a Taiwanese population.

  14. The effect of intravenous iron on postoperative transfusion requirements in hip fracture patients: study protocol for a randomized controlled trial

    PubMed Central

    2013-01-01

    Background Anaemia following hip fracture is common. Approximately 30 to 45% of patients have haemoglobin concentrations below population norms on admission, and around 10% are severely anaemic. Anaemia on admission, and in the postoperative period, is associated with poor outcomes with regard to mobility, postoperative mortality and readmission. There is currently no clear consensus on the optimal method of managing perioperative anaemia in this group of frail patients with frequent comorbidity. Liberal red cell transfusion in the postoperative period does not appear to improve outcome, whereas tranexamic acid appears to reduce transfusion rate at the expense of increased cardiovascular morbidity. There are encouraging results from one centre with the use of agents to stimulate red cell production, including intravenous iron and erythropoietin. UK practice differs significantly from these patients and these studies, and it is not clear whether these promising results will translate to the UK population. Methods/Design This is a single-centre randomized controlled parallel group trial, in a British university hospital.Randomization is achieved using a website and computer-generated concealed tables. Participants are 80 patients 70 years or over with acute hip fracture undergoing operative repair. The intervention group receive three daily infusions of 200 mg iron sucrose, starting within 24 hours of admission. The control group receive standard hospital care at the discretion of the clinical team. Red cell transfusions for each group are given in accordance with standard clinical triggers. The primary outcome is an increase in mean reticulocyte count in the intervention group at day 7. Secondary outcome measures include haemoglobin concentrations, early and late transfusion rates, infectious and cardiovascular complications, mobility and 30-day mortality. Discussion This is a pilot study to demonstrate haematopoietic efficacy of intravenous iron in this setting

    Purpose We aimed to see the frequency of concomitant ischemic heart disease (IHD) in Korean patients with abdominal aortic aneurysm (AAA) and to determine risk factors for an early postoperative acute myocardial infarction (PAMI) after elective open or endovascular AAA repair. Methods We retrospectively reviewed a database of patients who underwent elective AAA repair over the past 11 years. Patients were classified into 3 groups: control group; group I, medical IHD treatment; group II, invasive IHD treatment. Rates of PAMI and mortality at 30 days were compiled and compared between groups according to the type of AAA repair. Results Six hundred two elective repairs of infrarenal or juxtarenal AAAs were enrolled in this study. The patients were classified into control group (n = 398, 66.1%), group I (n = 73, 12.1%) and group II (n = 131, 21.8%). PAMI developed more frequently after open surgical repair (OSR) than after endovascular aneurysm repair (EVAR) (5.4% vs. 1.3%, P = 0.012). In OSR patients (n = 373), PAMI developed 2.1% in control group, 18.0% in group I and 7.1% in group II (P < 0.001). In EVAR group (n = 229), PAMI developed 0.6% in control group, 4.3% in group I and 2.2% in group II (P = 0.211). On the multivariable analysis of risk factors of PAMI, PAMI developed more frequently in patients with positive functional stress test. Conclusion The prevalence of concomitant IHD was 34% in Korean AAA patients. The risk of PAMI was significantly higher after OSR compared to EVAR and in patients with IHD compared to control group. Though we found some risk factors for PAMI, these were not applied to postoperative mortality rate. PMID:26942161

    High incidence of malnutrition is found in esophageal cancer patients. It is well known that to maintain good nutritional preoperative condition is very important to prevent postoperative morbidity and mortality. Hence, preoperative oral or nasogastric feeding is recommended when the patient is malnourished, at a total dose of 30 kcal/kg/day. During postoperative period, enteral nutrition should be primarily performed because of its favorable effects on immune-status and intestinal integrity to avoid septic complications. It is also important to keep circulatory volume sufficient to provide oxygen demand during catabolic phase, which leads earlier recovery from critical illness. Enteral nutrition should be immediately started afterward. An initial dose of 5-10 kcal/kg/day of the enteral nutrition is performed from the 1st or 2nd postoperative day and gradually increased to the full dose at 30 kcal/kg/ day. In cases of not administering scheduled dose of the enteral nutrition, either total or peripheral parenteral nutrition is required complementing total caloric intake. When total parenteral nutrition is used, blood glucose level should be controlled less than 150 mg/dl by pertinently administering insulin or limiting glycemic intake. Immunonutrition is promising nutritional management for critical surgical patients such as those performed esophageal cancer surgery. Continuing immune-enhancing diet at a dose of 750 to 1,000 ml/day for 5 to 7 days before surgery is necessary to bring good postoperative outcome. PMID:20715418

    Pulmonary complications are a major cause of morbidity and mortality in the post-operative period after thoracotomy. The type of complications and the severity of complications depend on the type of thoracic surgery that has been performed as well as on the patient's pre-operative medical status. Risk stratification can help in predicting the possibility of the post-operative complications. Certain airway complications are more prone to develop with thoracic surgery. Vocal cord injuries, bronchopleural fistulae, pulmonary emboli and post-thoracic surgery non-cardiogenic pulmonary oedema are some of the unique complications that occur in this subset of patients. The major pulmonary complications such as atelectasis, bronchospasm and pneumonia can lead to respiratory failure. This review was compiled after a search for search terms within ‘post-operative pulmonary complications after thoracic surgery and thoracotomy’ on search engines including PubMed and standard text references on the subject from 2000 to 2015.

    BACKGROUND: COPD is a leading cause of death and disability in the United States. Patients with COPD are at a high risk of nutritional deficiency, which is associated with declines in respiratory function, lean body mass and strength, and immune function. Although oral nutritional supplementation (ONS) has been associated with improvements in some of these domains, the impact of hospital ONS on readmission risk, length of stay (LOS), and cost among hospitalized patients is unknown. METHODS: Using the Premier Research Database, we first identified Medicare patients aged ≥ 65 years hospitalized with a primary diagnosis of COPD. We then identified hospitalizations in which ONS was provided, and used propensity-score matching to compare LOS, hospitalization cost, and 30-day readmission rates in a one-to-one matched sample of ONS and non-ONS hospitalizations. To further address selection bias among patients prescribed ONS, we also used instrumental variables analysis to study the association of ONS with study outcomes. Model covariates included patient and provider characteristics and a time trend. RESULTS: Out of 10,322 ONS hospitalizations and 368,097 non-ONS hospitalizations, a one-to-one matched sample was created (N = 14,326). In unadjusted comparisons in the matched sample, ONS use was associated with longer LOS (8.7 days vs 6.9 days, P < .0001), higher hospitalization cost ($14,223 vs $9,340, P < .0001), and lower readmission rates (24.8% vs 26.6%, P = .0116). However, in instrumental variables analysis, ONS use was associated with a 1.9-day (21.5%) decrease in LOS, from 8.8 to 6.9 days (P < .01); a hospitalization cost reduction of $1,570 (12.5%), from $12,523 to $10,953 (P < .01); and a 13.1% decrease in probability of 30-day readmission, from 0.34 to 0.29 (P < .01). CONCLUSIONS: ONS may be associated with reduced LOS, hospitalization cost, and readmission risk in hospitalized Medicare patients with COPD. PMID:25357165

    Objective Heart rate (HR) parameters are known indicators of cardiovascular complications after cardiac surgery, but there is little evidence of their role in predicting outcome after major vascular surgery. The purpose of this study was to determine whether arrival HR (AHR) and highest intraoperative HR are associated with mortality or major adverse cardiac events (MACEs) after elective vascular surgery in the Vascular Quality Initiative (VQI). Methods Patients undergoing elective lower extremity bypass (LEB), aortofemoral bypass (AFB), and open abdominal aortic aneurysm (AAA) repair in the VQI were analyzed. MACE was defined as any postoperative myocardial infarction, dysrhythmia, or congestive heart failure. Controlled HR was defined as AHR <75 beats/min on operating room arrival. Delta HR (DHR) was defined as highest intraoperative HR – AHR Procedure-specific MACE models were derived for risk stratification, and generalized estimating equations were used to account for clustering of center effects. HR, beta-blocker exposure, cardiac risk, and their interactions were explored to determine association with MACE or 30-day mortality. A Bonferroni correction with P < .004 was used to declare significance. Results There were 13,291 patients reviewed (LEB, n = 8155 [62%]; AFB, n = 2629 [18%]; open AAA, n = 2629 [20%]). Rates of any preoperative beta-blocker exposure were as follows: LEB, 66.5% (n = 5412); AFB, 57% (n = 1342); and open AAA, 74.2% (n = 1949). AHR and DHR outcome association was variable across patients and procedures. AHR <75 beats/min was associated with increased postoperative myocardial infarction risk for LEB patients across all risk strata (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.03–1.9; P = .03), whereas AHR<75 beats/min was associated with decreased dysrhythmia risk (OR, 0.42; 95% CI, 0.28–0.63; P = .0001) and 30-day death (OR, 0.50; 95% CI, 0.33–0.77; P = .001) in patients at moderate and high cardiac risk.

    The aim of this study was to determine the transversal stiffness of the cortical cytoskeleton and the cytoskeletal protein desmin content in the left ventricle cardiomyocytes, fibers of the mouse soleus and tibialis anterior muscle after a 30-day space flight on board the "BION-M1" biosatellite (Russia, 2013). The dissection was made after 13-16.5 h after landing. The transversal stiffness was measured in relaxed and calcium activated state by, atomic force microscopy. The desmin content was estimated by western blotting, and the expression level of desmin-coding gene was detected using real-time PCR. The results indicate that, the transversal stiffness of the left ventricle cardiomyocytes and fibers of the soleus muscle in relaxed and activated states did not differ from the control. The transversal stiffness of the tibialis muscle fibers in relaxed and activated state was increased in the mice group after space flight. At the same time, in all types of studied tissues the desmin content and the expression level of desmin-coding gene did not differ from the control level. PMID:25730983

    Changes in isoform composition, gene expression of titin and nebulin, and isoform composition of myosin heavy chains as well as changes in titin phosphorylation level in skeletal (m. gastrocnemius, m. tibialis anterior, and m. psoas) and cardiac muscles of mice were studied after a 30-day-long space flight onboard the Russian spacecraft "BION-M" number 1. A muscle fibre-type shift from slow-to-fast and a decrease in the content of titin and nebulin in the skeletal muscles of animals from "Flight" group was found. Using Pro-Q Diamond staining, an ~3-fold increase in the phosphorylation level of titin in m. gastrocnemius of mice from the "Flight" group was detected. The content of titin and its phosphorylation level in the cardiac muscle of mice from "Flight" and "Control" groups did not differ; nevertheless an increase (2.2 times) in titin gene expression in the myocardium of flight animals was found. The observed changes are discussed in the context of their role in the contractile activity of striated muscles of mice under conditions of weightlessness. PMID:25664316

    2015-08-01

    A new randomized trial shows patients who present to the ED with opioid dependence are much more likely to engage in treatment when they receive buprenorphine along with coordinated follow-up than when they just receive a brief intervention and a facilitated referral for treatment or just screening and referral. However, barriers to prescribing are robust, and many ED leaders are not persuaded they should be in the business of providing treatment for addiction. In the trial, at 30 days 78% of patients in the buprenorphine group (89 of 114 patients) were engaged in addiction treatment, compared with just 45% of the patients in the brief intervention group (50 of 111 patients) and 37% of patients in the referral group (38 of 102 patients). To prescribe buprenorphine for addiction disease, providers must undergo training and pass a test to obtain a DEA waiver; they are limited to treating 100 patients. While experts note there are not enough providers to prescribe buprenorphine and provide the follow-up needed to patients with addiction disease, they also acknowledge concerns about drug diversion as well as potential problems with capacity if EDs take a larger role in treating addiction.

    This intervention study was conducted in Albania to establish the superiority of the Fridge-tag (30-day electronic refrigerator temperature logger) against thermometers. Intervention sites used Fridge-tag and a modified temperature control record sheet, while control sites continued with their routine operation with thermometers. All refrigerators in both groups were equipped with downloadable electronic data loggers to record temperatures for reference. Focus group sessions were conducted with involved staff to discuss temperature monitoring, Fridge-tag use and its user-friendliness. Significant discrepancies were observed between thermometer readings and the electronic data loggers in control sites, while all alarms from Fridge-tag were confirmed in the intervention group. Thermometers are not sufficient to monitor temperatures in refrigerators since they miss the great majority of low and high alarms. Fridge-tag has proven to be an effective tool in providing health workers with the information they need to take the necessary actions when there are refrigerator temperature variations.

    Exposure to microgravity results in various structural, biochemical and molecular changes of the skeletal neuromuscular system. The BION Joint Flight Proposal between the Charité Berlin Center of Space Medicine (www.zwmb.de) in Berlin, and the Institute of Biomedical Problem (IMBP) in Moscow, provided an exciting opportunity for a more detailed analysis of neuromuscular changes in mice (C57/bl6) exposed to real microgravity housed for 30 days in a BION M1 biosatellite on orbit. The mice from the BION flight group (n=5) were compared to three different on-ground control groups (Flight control, BION-ground and Vivarium, each n=5 mice). We started to analyse various skeletal muscles from the hind limbs or trunk. Apart from routine structural and biochemical analysis (fiber size and type distribution, slow/fastMyHC) we test the hypothesis for the presence of a microgravity-induced sarcolemma-cytosolic protein shift of nitric oxide synthase (NOS) and partial loss in neuromuscular synapse scaffold protein (Homer) immunoexpression known to be prone to disuse in mice or humans (hind limb unloading, bed rest) as previously shown (Sandonà D et al., PLoS One, 2012, Salanova M et al., FASEB J, 2011).

The observed changes are discussed in the context of their role in the contractile activity of striated muscles of mice under conditions of weightlessness. PMID:25664316

    Postoperative pain is a very important issue for several patients. Indifferent of the surgery type or method, pain management is very necessary. The relief from suffering leads to early mobilization, less hospital stay, reduced hospital costs, and increased patient satisfaction. An individual approach should be applied for pain control, rather than a fix dose or drugs. Additionally, medical, psychological, and physical condition, age, level of fear or anxiety, surgical procedure, personal preference, and response to agents given should be taken into account. The major goal in the management of postoperative pain is minimizing the dose of medications to lessen side effects while still providing adequate analgesia. Again a multidisciplinary team approach should be pursued planning and formulating a plan for pain relief, particularly in complicated patients, such as those who have medical comorbidities. These patients might appear increase for analgesia-related complications or side effects. PMID:25774311

    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

    Objective To determine whether preoperative biliary instrumentation and preoperative biliary drainage are associated with increased morbidity and mortality rates after pancreaticoduodenectomy. Summary Background Data Pancreaticoduodenectomy is accompanied by a considerable rate of postoperative complications and potential death. Controversy exists regarding the impact of preoperative biliary instrumentation and preoperative biliary drainage on morbidity and mortality rates after pancreaticoduodenectomy. Methods Two hundred forty consecutive cases of pancreaticoduodenectomy performed between January 1994 and January 1997 were analyzed. Multiple preoperative, intraoperative, and postoperative variables were examined. Pearson chi square analysis or Fisher’s exact test, when appropriate, was used for univariate comparison of all variables. Logistic regression was used for multivariate analysis. Results One hundred seventy-five patients (73%) underwent preoperative biliary instrumentation (endoscopic, percutaneous, or surgical instrumentation). One hundred twenty-six patients (53%) underwent preoperative biliary drainage (endoscopic stents, percutaneous drains/stents, or surgical drainage). The overall postoperative morbidity rate after pancreaticoduodenectomy was 48% (114/240). Infectious complications occurred in 34% (81/240) of patients. Intraabdominal abscess occurred in 14% (33/240) of patients. The postoperative mortality rate was 5% (12/240). Preoperative biliary drainage was determined to be the only statistically significant variable associated with complications (p = 0.025), infectious complications (p = 0.014), intraabdominal abscess (p = 0.022), and postoperative death (p = 0.037). Preoperative biliary instrumentation alone was not associated with complications, infectious complications, intraabdominal abscess, or postoperative death. Conclusions Preoperative biliary drainage, but not preoperative biliary instrumentation alone, is associated with increased

    The purpose of this paper is to describe what I have studied and experienced, mainly regarding the control and prediction of the postoperative edema; how to achieve an agreeable recovery and give positive support to the patient, who in turn will receive pleasant sensations that neutralize the negative consequences of the surgery.After the skin is lifted, the drainage flow to the flaps is reversed abruptly toward the medial part of the face, where the flap bases are located. The thickness and extension of the flap determines the magnitude of the post-op edema, which is also augmented by medial surgeries (blepharo, rhino) whose trauma obstruct their natural drainage, increasing the congestion and edema. To study the lymphatic drainage, the day before an extended face lift (FL) a woman was infiltrated in the cheek skin with lynfofast (solution of tecmesio) and the absorption was observed by gamma camera. Seven days after the FL she underwent the same study; we observed no absorption by the lymphatic, concluding that a week after surgery, the lymphatic network was still damaged. To study the venous return during surgery, a fine catheter was introduced into the external jugular vein up to the mandibular border to measure the peripheral pressure. Following platysma plication the pressure rose, and again after a simple bandage, but with an elastic bandage it increased even further, diminishing considerably when it was released. Hence, platysma plication and the elastic bandage on the neck augment the venous congestion of the face. There are diseases that produce and can prolong the surgical edema: cardiac, hepatic, and renal insufficiencies, hypothyroidism, malnutrition, etc. According to these factors, the post-op edema can be predicted, the surgeon can choose between a wide dissection or a medial surgery, depending on the social or employment compromises the patient has, or the patient must accept a prolonged recovery if a complex surgery is necessary.

    Anastomotic dehiscence (AD) requiring reoperation is the most severe complication following anterior rectal resection. We performed a systematic review on studies that describe AD requiring reoperation and its subsequent mortality after anterior resection for rectal carcinoma. A systematic search was performed on published literature. Data on the definition and rate of AD, the number of ADs requiring reoperation, the mortality caused by AD, and the overall postoperative mortality were pooled and analyzed. A total of 39 studies with 24,232 patients were analyzed. The studies varied in incidence and definition of AD. Systematic review of the data showed that the overall rate of AD was 8.6%, and the rate of AD requiring reoperation was 5.4%. The postoperative mortality caused by AD was 0.4%, and the overall postoperative mortality was 1.3%. We found considerable risk and mortality for AD requiring reoperation, which largely contributed to the overall postoperative mortality. PMID:24670019

    Purpose: While trimodality therapy for esophageal cancer has improved patient outcomes, surgical complication rates remain high. The goal of this study was to identify modifiable factors associated with postoperative complications after neoadjuvant chemoradiation. Methods and Materials: From 1998 to 2011, 444 patients were treated at our institution with surgical resection after chemoradiation. Postoperative (pulmonary, gastrointestinal [GI], cardiac, wound healing) complications were recorded up to 30 days postoperatively. Kruskal-Wallis tests and χ{sup 2} or Fisher exact tests were used to assess associations between continuous and categorical variables. Multivariate logistic regression tested the association between perioperative complications and patient or treatment factors that were significant on univariate analysis. Results: The most frequent postoperative complications after trimodality therapy were pulmonary (25%) and GI (23%). Lung capacity and the type of radiation modality used were independent predictors of pulmonary and GI complications. After adjusting for confounding factors, pulmonary and GI complications were increased in patients treated with 3-dimensional conformal radiation therapy (3D-CRT) versus intensity modulated radiation therapy (IMRT; odds ratio [OR], 2.018; 95% confidence interval [CI], 1.104-3.688; OR, 1.704; 95% CI, 1.03-2.82, respectively) and for patients treated with 3D-CRT versus proton beam therapy (PBT; OR, 3.154; 95% CI, 1.365-7.289; OR, 1.55; 95% CI, 0.78-3.08, respectively). Mean lung radiation dose (MLD) was strongly associated with pulmonary complications, and the differences in toxicities seen for the radiation modalities could be fully accounted for by the MLD delivered by each of the modalities. Conclusions: The radiation modality used can be a strong mitigating factor of postoperative complications after neoadjuvant chemoradiation.

    Dynamic variations in early selective attention to the color and direction of moving stimuli were explored during a 30 days period of head-down bed rest. Event-related potentials (ERPs) were recorded at F5, F6, P5, P6 scalp locations in seven male subjects who attended to pairs of bicolored light emitting diodes that flashed sequentially to produce a perception of movement. Subjects were required to attend selectively to a critical feature of the moving target, e.g., color or direction. The tasks included: a no response task, a color selective response task, a moving direction selective response task, and a combined color-direction selective response task. Subjects were asked to perform these four tasks on: the 3rd day before bed rest; the 3rd, 15th and 30th day during the bed rest; and the 5th day after bed rest. Subjects responded quickly to the color than moving direction and combined color-direction response. And they had a longer reaction time during bed rest on the 15th and 30th day during bed rest after a relatively quicker response on the 3rd day. Using brain event-related potentials technique, we found that in the color selective response task, the mean amplitudes of P1 and N1 for target ERPs decreased in the 3rd day during bed rest and 5th day after bed rest in comparison with pre-bed rest, 15th day and 30th day during bed rest. In the combined color-direction selective response task, the P1 latencies for target ERPs on the 3rd and 30th day during bed rest were longer than on the 15th day during bed rest. As 3rd day during bed rest was in the acute adaptation period and 30th day during bed rest was in the relatively adaptation stage of head-down bed rest, the results help to clarify the effects of bed rest on different task loads and patterns of attention. It was suggested that subjects expended more time to give correct decision in the head-down tilt bed rest state. A difficulty in the recruitment of brain resources was found in feature selection task

    Background Lifestyle behavior modification can reduce the risk of cardiovascular disease, one of the leading causes of death worldwide, by up to 80%. We hypothesized that a dynamic risk assessment and behavior change tool delivered as a mobile app, hosted by a reputable nonprofit organization, would promote uptake among community members. We also predicted that the uptake would be influenced by incentives offered for downloading the mobile app. Objective The primary objective of our study was to evaluate the engagement levels of participants using the novel risk management app. The secondary aim was to assess the effect of incentives on the overall uptake and usage behaviors. Methods We publicly launched the app through the iTunes App Store and collected usage data over 5 months. Aggregate information included population-level data on download rates, use, risk factors, and user demographics. We used descriptive statistics to identify usage patterns, t tests, and analysis of variance to compare group means. Correlation and regression analyses determined the relationship between usage and demographic variables. Results We captured detailed mobile usage data from 69,952 users over a 5-month period, of whom 23,727 (33.92%) were registered during a 1-month AIR MILES promotion. Of those who completed the risk assessment, 73.92% (42,380/57,330) were female, and 59.38% (34,042/57,330) were <30 years old. While the older demographic had significantly lower uptake than the younger demographic, with only 8.97% of users aged ≥51 years old downloading the app, the older demographic completed more challenges than their younger counterparts (F 8, 52,422 = 55.10, P<.001). In terms of engagement levels, 84.94% (44,537/52,431) of users completed 1–14 challenges over a 30-day period, and 10.03% (5,259/52,431) of users completed >22 challenges. On average, users in the incentives group completed slightly more challenges during the first 30 days of the intervention (mean 7.9, SD 0

    The last stage of fetal development and the neonatal period represent the most critical phases for the mammals' offspring. In the dog, the knowledge about the final intrauterine fetal development and biology, as well as about the neonatal physiology, remains scarce. Hormonal changes occurring in the last intrauterine fetal phase and during the early neonatal age are still not completely clear, probably because of the invasiveness related to the collection of the more common biological matrix, represented by circulating blood. Toward term of pregnancy, during parturition, and after birth, the hypothalamic-pituitary-adrenal axis is a key system regulating several physiological processes, and its activity was previously investigated by blood analysis, considered an invasive procedure providing a single-point measurement. In respect to animal welfare, and for a more correct long-term retrospective investigation, noninvasive hormonal studies were performed firstly on the hair of humans and coat of animals and, more recently, in the nails of human beings. This study was aimed to assess cortisol (COR) in coat and claws of newborn puppies and to evaluate the possible influence of the newborn gender, breed body size, and age on coat and claws COR concentrations. The results obtained from 165 newborn puppies evidenced that coat and claws COR levels were highly correlated each other (P < 0.0001), although the COR accumulation in the two matrices was different in relation to the class of age. Moreover, the puppies age influenced both coat and claws COR concentrations (P < 0.05), with premature puppies showing higher values when compared to term born-dead puppies or puppies dead between 1 and 30 days of age. The present study reported that COR is quantifiable in coat and claws of newborn dogs. Moreover, both matrices appear as useful tools for new, noninvasive, long-term perinatal and neonatal researches also in canine species. PMID:26081135

    Peritoneal adhesions represent an important clinical challenge in gastrointestinal surgery. Peritoneal adhesions are a consequence of peritoneal irritation by infection or surgical trauma, and may be considered as the pathological part of healing following any peritoneal injury, particularly due to abdominal surgery. The balance between fibrin deposition and degradation is critical in determining normal peritoneal healing or adhesion formation. Postoperative peritoneal adhesions are a major cause of morbidity resulting in multiple complications, many of which may manifest several years after the initial surgical procedure. In addition to acute small bowel obstruction, peritoneal adhesions may cause pelvic or abdominal pain, and infertility. In this paper, the authors reviewed the epidemiology, pathogenesis and various prevention strategies of adhesion formation, using Medline and PubMed search. Several preventive agents against postoperative peritoneal adhesions have been investigated. Their role aims in activating fibrinolysis, hampering coagulation, diminishing the inflammatory response, inhibiting collagen synthesis or creating a barrier between adjacent wound surfaces. Their results are encouraging but most of them are contradictory and achieved mostly in animal model. Until additional findings from future clinical researches, only a meticulous surgery can be recommended to reduce unnecessary morbidity and mortality rates from these untoward effects of surgery. In the current state of knowledge, pre-clinical or clinical studies are still necessary to evaluate the effectiveness of the several proposed prevention strategies of postoperative peritoneal adhesions.

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    An audit project was designed to assess and improve the provision of postoperative analgesia in a children's hospital. Pain assessment for all children and analgesia standards for our institution were introduced prior to data collection. Data were collected on consecutive samples of 316 and 325 children undergoing surgery as inpatients during 10-week periods. Change was initiated between the two periods in response to our findings; our action plan involved education, changes to documentation, the widespread use of diclofenac in children over 2 years of age and recommendations for the prescription of analgesia. The initial prescription of analgesia increased from 95% to 98% (p = 0.019), administration of analgesia to children experiencing bad or severe pain increased from 57% to 71% (p = 0.032) and the number of children experiencing severe pain reduced from 17% to 11% (p = 0.050). Application of audit, by a clinical nurse specialist, enabled us to achieve and demonstrate improvements in the prescription, administration and effectiveness of postoperative analgesia.

    This is a report on clinical experience had with 17 patients presenting necrotizing fasciitis--a complication ever more frequently encountered. The case material is distributed in two group differing by origin and clinical course of the complication. In group one (n = 11) it is a matter of postoperative development of postoperative complication, consistent with the classical "per continuitatem" and "per contiguitatem" mechanisms, while in group two (n = 6) the process originates, evolves and speads within the retroperitoneal space proper. Comprehensive microbiological examinations performed in 13 cases show that in either group different microorganisms are identified. In group one aerobic-anaerobic mixed infection is documented in all patients, with predominance of Enterobacteroidaceae among aerobic ones. In group two, anaerobic bacterial species, mainly Clostridium sp, prevail in all the isolates. The clinical study points to a substantial difference in the time of septic complication occurrence, as well as between the clinical picture of the two species. Accordingly, the final results are radically different--in group one survivorship amounts to 62.6%, whereas in group two--to 16.6% only. PMID:11692928

    The incidence of Candida bloodstream infections (BSIs) has increased over time, especially in medical wards. The objective of this study was to evaluate the impact of different antifungal treatment strategies on 30-day mortality in patients with Candida BSI not admitted to intensive care units (ICUs) at disease onset. This prospective, monocentric, cohort study was conducted at an 1100-bed university hospital in Rome, Italy, where an infectious disease consultation team was implemented. All cases of Candida BSIs observed in adult patients from November 2012 to April 2014 were included. Patients were grouped according to the initial antifungal strategy: fluconazole, echinocandin, or liposomal amphotericin B. Cox regression analysis was used to identify risk factors significantly associated with 15-day and 30-day mortality. During the study period, 130 patients with candidemia were observed (58 % with C. albicans, 7 % with C. glabrata, and 23 % with C. parapsilosis). The first antifungal drug was fluconazole for 40 % of patients, echinocandin for 57.0 %, and liposomal amphotericin B for 4 %. During follow-up, 33 % of patients died. The cumulative mortality 30 days after the candidemia episode was 30.8 % and was similar among groups. In the Cox regression analysis, clinical presentation was the only independent factor associated with 15-day mortality, and Acute Physiology and Chronic Health Evaluation (APACHE) II score and clinical presentation were the independent factors associated with 30-day mortality. No differences in 15-day and 30-day mortality were observed between patients with and without C. albicans candidemia. In patients with candidemia admitted to medical or surgical wards, clinical severity but not the initial antifungal strategy were significantly correlated with mortality. PMID:26634352

    The aim of this study was to determine transversal stiffness of the cortical cytoskeleton and cytoskeletal protein desmin content of the left ventricle cardiomyocytes, soleus and tibialis anterior muscle fibers of the mice after 30-days space flight biosatellite «BION-M1» (Russia, 2013). The dissection was made after 13-16.5 hours after landing. Transversal stiffness was measured in relaxed and calcium activated state by atomic force microscope. Desmin content was estimated by using western-blot, expression level of the gene, coding desmin, - by real time PCR. The transversal stiffness of the cortical cytoskeleton of the cardiomyocytes and fibers of the skeletal muscles (as measured using the atomic force microscopy) did not differ significantly within the study groups in comparison to the vivarium control group, except for its slight increase in tibialis anterior fibers muscle in the post-flight group of animals. The content of beta- and gamma-actin in the membranous fraction of proteins in the left ventricular cardiomyocytes (as detected using the western blot technique) did not differ significantly within all study groups and correlated with the transversal stiffness. Similar situation was revealed in fibers of the soleus muscle and tibialis anterior muscle, as well as correlation with the transversal stiffness of their cortical cytoskeleton was noted. At the same time, the content of beta-actin in the cytoplasmic fraction of proteins was found to be decreased in all types of studied tissues in comparison to the control levels in the post-flight group, as well as lowered beta-actin gene expression rates in the post-flight group of animals (as detected using the RT-PCR technique). After completion of the space flight, content of alpha-actinin-4 was found to be reduced in the membranous fraction of proteins of mouse cardiomyocytes, while its content in the cytoplasmic fraction of proteins did not change significantly. Furthermore, gene expression rates of this

    During 30 days (d) of bedrest, the practicality of using Elec- troMyoStimulation (EMS) as a deterrent to atrophy and strength loss of lower limb musculature was examined. An EMS system was developed that provided variable but quantifiable levels of EMS, and measured torque. The dominant log of three male subjects was stimulated twice daily in a 3-d on/1-d off cycle during bedrest. The non-dominant leg of each subject acted as a control. A stimulator, using a 0.3 ms monophasic 60 Hz pulse waveform, activated muscle tissue for 4 s. The output waveform from the stimulator was sequenced to the Knee Extensors (KE), Knee Flex- ors (KF), Ankle Extensors (AE), and Ankle Flexors (AF), and caused three isometric contractions of each muscle group per minute. Subject tolerance determined EMS Intensity. Each muscle group received four 5-min bouts of EMS each session with a 10 -min rest between bouts. EMS and torque levels for each muscle action were recorded directly an a computer. Overall average EMS Intensity was 197, 197, 195, and 188 mA for the KE, KF, AF, and AE, respectively. Overall average torque development for these muscle groups was 70, 16, 12, and 27 Nm, respectively. EMS intensity doubled during the study, and average torque increased 2.5 times. Average maximum torque throughout a session reached 54% of maximal voluntary for the KE and 29% for the KF. Reductions in leg volume, muscle compartment size, cross-sectional area of slow and fast-twitch fibers, strength, and aerobic enzyme activities, and increased log compliance were attenuated in the legs which received EMS during bedrest. These results indicate that similar EMS levels induce different torques among different muscle groups and that repeated exposure to EMS increases tolerance and torque development. Longer orien- tation periods, therefore, may enhance its effectiveness. Our preliminary data suggest that the efficacy of EMS as an effective countermeasure for muscle atrophy and strength loss during long

    The occurrence of postoperative pulmonary complications is strongly associated with increased hospital mortality and prolonged postoperative hospital stays. Although protective lung ventilation is commonly used in the intensive care unit, low tidal volume ventilation in the operating room is not a routine strategy. Low tidal volume ventilation, moderate positive end-expiratory pressure, and repeated recruitment maneuvers, particularly for high-risk patients undergoing major abdominal surgery, can reduce postoperative pulmonary complications. Facilitating perioperative bundle care by combining prophylactic and postoperative positive-pressure ventilation with intraoperative lung-protective ventilation may be helpful to reduce postoperative pulmonary complications.

    Immunosuppressive therapy is the main postoperative treatment for keratoplasty, but there are considerable differences in protocols for the use of steroids and other immunosuppressants. Therefore, we conducted 2 prospective randomized clinical trials and 1 prospective nonrandomized clinical trial on keratoplasty postoperative treatment. One study evaluated the efficacy and safety of long-term topical corticosteroids after a penetrating keratoplasty was performed. Patients who underwent keratoplasty and maintained graft clarity for >1 year were randomly assigned to either a steroid or a no-steroid group. At the 12-month follow-up, the no-steroid group developed significantly more endothelial rejection than did the steroid group. A second study elucidated the effectiveness and safety of systemic cyclosporine in high-risk corneal transplantation. The patients were assigned to a systemic cyclosporine or control group. At a mean follow-up of 42.7 months, no difference was observed in the endothelial rejection rates and graft clarity loss between the 2 groups. A third study elucidated the effectiveness and the safety of systemic tacrolimus in high-risk corneal transplantation. Of 11 consecutive eyes decompensated despite systemic cyclosporine treatment, there was no irreversible rejection in eyes treated with tacrolimus, which was significantly better than in previous penetrating keratoplasty with systemic cyclosporine treatment. Prognosis after keratoplasty in patients with keratoconus is relatively good, but special attention is required for patients with atopic dermatitis. Postkeratoplasty atopic sclerokeratitis (PKAS) is a severe form of sclerokeratitis after keratoplasty in atopic patients. Our retrospective study showed that 35 eyes of 29 patients from a total of 247 keratoconus eyes undergoing keratoplasty were associated with atopic dermatitis, of which 6 eyes of 5 patients developed PKAS. Eyes with PKAS had a significantly higher incidence of atopic blepharitis

    Objective Assess the impact of preoperative serum anti-TNFα drug levels on 30-day postoperative morbidity in inflammatory bowel disease patients. Summary Background Data Studies on the association of anti-TNFα drugs and postoperative outcomes in IBD are conflicting due to variable pharmacokinetics of anti-TNFα drugs.. It remains to be seen whether preoperative serum anti-TNFα drug levels correlate with postoperative morbidity. Methods 30 days postoperative outcomes of consecutive IBD surgical patients with serum drawn within 7 days pre-operatively, were studied. The total serum level of 3 anti-TNF-α drugs (infliximab, adalimumab, certolizumab) was measured, with ≥0.98 µg/ml considered as detected. Data was also reviewed according to a clinical cut off value of 3 µg/ml. Results 217 patients (123 Crohn’s disease (CD) and 94 ulcerative colitis (UC)) were analyzed. 75 of 150 (50%) treated with anti-TNFα therapy did not have detected levels at the time of surgery. In the UC cohort, adverse postoperative outcomes rates between the undetectable and detectable groups were similar when stratified according to type of UC surgery. In the CD cohort, there was a higher but statistically insignificant rate of adverse outcomes in the detectable vs undetectable groups. Using acut-off level of 3 µg/ml, postoperative morbidity (OR=2.5, p=0.03) and infectious complications (OR=3.0, p=0.03) were significantly higher in the ≥ 3 µg/ml group. There were higher rates of postoperative morbidity (p=0.047) and hospital readmissions (p=0.04) in the ≥ 8 µg/ml compared to < 3 µg/ml group. Conclusion Increasing preoperative serum anti-TNFα drug levels are associated with adverse postoperative outcomes in CD but not UC patients. PMID:24950263

    Although often a life-saving therapeutic maneuver, there is minimal data available that details the effects of intraoperative packed red blood cell transfusion (IOT) after microvascular free tissue transfer. The National Surgical Quality Improvement Program database was queried to identify all patients who underwent microvascular free tissue transfer between 2006 and 2010. Multivariate logistic regression models were used to determine the association between intraoperative transfusion and outcomes. Upon bivariate and multivariate analyses, IOT was significantly associated with higher rates of overall complications (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.12-3.63), medical complications (OR, 3.35; 95% CI, 1.75-6.42), postoperative transfusion (OR, 6.02; 95% CI, 2.02-17.97), and reoperation (OR, 2.24; 95% CI, 1.24-4.04). IOT was not associated with either surgical complications or free flap loss. IOT significantly increases risk for adverse overall and medical complications. However, IOT was not associated with surgical complications or free flap loss. Transfusion practices in the operating room should be reevaluated to improve overall outcomes. PMID:24114710

    This paper describes an experimental model of peritoneal adhesions, in the rat, based on two relatively minor accidents that may occur during abdominal surgery in man: drying of the serosa, and bleeding. Drying alone had little effect; drying plus bleeding consistently produced adhesions to the dried area. Fresh blood alone produced adhesions between the three membranous structures [omentum and pelvic fat bodies (PFBs)]. The formation of persistent adhesions required whole blood. Preformed clots above a critical size induced adhesions even without previous serosal injury; they were usually captured by the omentum and PFBs. If all three membranous structures were excised, the clots caused visceral adhesions. The protective role of the omentum, its structure, and the mechanism of omental adhesions, are discussed. These findings are relevant to the pathogenesis of post-operative adhesions in man. ImagesFig 3Fig 4Fig 5Fig 6Fig 7Fig 12Fig 13Fig 1Fig 2Fig 14Fig 15Fig 8Fig 9Fig 10Fig 11 PMID:5315369

    Background The preoperative coexisting chronic systemic illness, delay in surgery, gender, and age were considered as risk factors for the complications after hip fracture surgery. The wider range of surgical delay and immobility-related pulmonary morbidity may affect postoperative complications and mortality. This study examined the risk factors for morbidity and mortality following the hip fracture surgery. Methods The patient data was collected retrospectively. The consecutive 506 patients with hip fracture surgery, aged 60 years or older, were included. The patients' age, gender, preexisting diseases, American Society of Anesthesiologists (ASA) classification, delay in surgical repair, duration of surgical procedure, and methods of anesthesia were noted. The thirty-day postoperative complications were reviewed, and cardiac complications, pulmonary complications, delirium, and death were recorded. The data was analyzed for postoperative complications and risk factors. Results Atelectasis was associated with postoperative pulmonary complications. Male gender and age ≥ 80 years were associated with an increased incidence of postoperative delirium. ASA classification 3 was associated with death. A delay in surgery was not associated with any complications. Preexisting diseases and methods of anesthesia did not affect mortality and postoperative complications. Conclusions The results suggest that a delay in surgery did not affect the postoperative complications and morbidity. PMID:23814650

    Outcomes from patients suffering hip fracture remain poor, with 9% mortality at 30 days and 35% at 1 year. Despite robust guidelines these mortality rates have undergone little change. Admission serum lactate in patients with sepsis or suffering general trauma has been shown to be an indicator of adverse clinical outcomes. We investigated whether venous lactate can predict mortality for hip fracture patients. Over a 12-month period the admission venous lactate of all patients presenting to our institution with hip fractures was prospectively collated. Demographic and patient survivorship data were also prospectively recorded. Multivariate binary logistic regression and Cox proportional hazards ratio analysis was used to evaluate the relationship between admission venous lactate and 30-day mortality and early survivorship, whilst adjusting for age and gender. 770 patients were included in the study. The mean age was 80 years. The overall 30-day mortality for this cohort was 9.5%. Admission venous lactate was associated with early death. A 1mmol/L increase in venous lactate resulted in a 1.9 (95% CI 1.5-2.3 p<0.0001) fold increase in the odds of 30-day mortality and a 1.4 (95% CI: 1.2-1.6 p<0.0001) factor increase in the risk of death at any time after hip fracture. Admission venous lactate remained a predictor of mortality despite adjustment for patients American Society of Anesthesiologists (ASA) grade. Those with an admission serum lactate of 3mmol/L or greater were particularly at risk. This cohort had a 30-day mortality odds that was 5-fold higher than those whose level was less than 3mmol/L (p<0.0001) and at any-time risk of death that was 1.9 times higher (p<0.0001). Those with a level of less than 3mmol/L had a 30-day mortality of 6.8%. For those with an admission venous lactate of 3mmol/L or greater this was four times higher at 28%. The difference was statistically significant (p<0.0001). Elevated admission venous lactate following hip fracture is a

    BACKGROUND: This study was undertaken to test the hypothesis that early enteral nutrition might reduce the incidence of serious complications after major abdominal surgery. METHODS: In a randomised double blind prospective trial 30 patients received Nutri-drink and 30 patients received placebo through a nasoduodenal feeding tube. On the day of operation the patients were given median 600 ml of either nutrition or placebo, 60 ml per hour. On the first postoperative day the patients received either 1000 ml (median) of nutrition or placebo, on day 2 1200 ml (median) nutrition, 1400 ml placebo, on day 3 1000 ml (median) nutrition, 1150 ml placebo, and on day 4 1000 ml (median) nutrition, 800 ml placebo. All patients were followed up for 30 days by the same investigator. RESULTS: The two groups were similar with regard to nutritional status and type of operation. The rate of postoperative infectious complications was significantly lower in the nutrition group, two of 30 compared with 14 of 30 in the placebo group (p = 0.0009). CONCLUSION: Early enteral nutrition given to patients after major abdominal surgery results in an important reduction in infectious complications. PMID:9038665

    Delirium is a common complication in the geriatric population following cardiac and noncardiac procedures. Postoperative delirium is a significant financial burden on the United States health care system and is independently associated with prolonged hospital stay, increased risk of early and long term mortality, increased physical dependence, and an increased rate of nursing home placement. The Confusion Assessment Method (CAM) is a bedside rating scale developed to assist nonpsychiatrically trained clinicians in the rapid and accurate diagnosis of delirium. The CAM has been adapted for use in ventilated intensive care unit (ICU) patients in the form of the CAM-ICU. The onset of delirium involves an interaction between predisposing and precipitating risk factors for delirium. The mainstay of delirium management is prevention. The approach involves control or elimination of modifiable risk factors. It is controversial whether anesthetic technique determines delirium. However, important modifiable risk factors under the anesthesiologist's control include adequate postoperative pain management, careful drug selection, and embracing and participating in a multidisciplinary care model for these complicated patients.

    Abstract Coronary artery disease is common in patients with chronic obstructive pulmonary disease (COPD). Previous studies have shown that patients with COPD have a higher risk of mortality than those without COPD after coronary artery bypass grafting (CABG). However, most of the previous studies were small, single-center studies with limited case numbers (or their only focus was mortality). The aim of our study was to focus on readmission, acute myocardial infarction (AMI), acute respiratory failure (ARF), cerebrovascular accident, and venous thromboembolism rates after CABG in an Asian COPD population. We conducted a nationwide case–control study in Taiwan using the claims database of hospitalization between January 1, 2009 and December 31, 2013. Patients with COPD before CABG were defined as the case groups. Each case was propensity score-matched by age, sex, hypertension, diabetes, dyslipidemia, cardiovascular disease, cerebrovascular disease, and chronic kidney disease, with 2 controls selected from CABG patients without COPD. The outcomes of interest were mortality, wound infection, and the readmission rate over 30 days for the following diseases: AMI, pneumonia, ARF, cerebrovascular accident, and venous thromboembolism. There were 14,858 patients without COPD and 758 patients with COPD who underwent CABG. After propensity score matching, the 30-day mortality and 30-day readmission rates and AMI were higher in the non-COPD group. The incidences of pneumonia and ARF after CABG were higher in the COPD group. Chronic obstructive pulmonary disease does not necessarily lead to mortality, readmission, or AMI after CABG, and the major respiratory complications associated with CABG in patients with COPD were pneumonia and ARF.

    Objective For peripheral arterial disease, infrainguinal bypass grafting (BPG) carries a higher perioperative risk compared with peripheral endovascular procedures. The choice between the open and endovascular therapies is to an extent dependent on the expected periprocedural risk associated with each. Tools for estimating the periprocedural risk in patients undergoing BPG have not been reported in the literature. The objective of this study was to develop and validate a calculator to estimate the risk of perioperative mortality30 days of elective BPG. Methods We identified 9556 patients (63.9% men) who underwent elective BPG from the 2007 to 2009 National Surgical Quality Improvement Program data sets. Multivariable logistic regression analysis was performed to identify risk factors associated with 30-day perioperative mortality. Bootstrapping was used for internal validation. The risk factors were subsequently used to develop a risk calculator. Results Patients had a median age of 68 years. The 30-day mortality rate was 1.8% (n = 170). Multivariable logistic regression analysis identified seven preoperative predictors of 30-day mortality: increasing age, systemic inflammatory response syndrome, chronic corticosteroid use, chronic obstructive pulmonary disease, dependent functional status, dialysis dependence, and lower extremity rest pain. Bootstrapping was used for internal validation. The model demonstrated excellent discrimination (C statistic, 0.81; bias-corrected C statistic, 0.81) and calibration. The validated risk model was used to develop an interactive risk calculator using the logistic regression equation. Conclusions The validated risk calculator has excellent predictive ability for 30-day mortality in a patient after an elective BPG. It is anticipated to aid in surgical decision making, informed patient consent, preoperative optimization, and consequently, risk reduction. PMID:22632800

    Little is known about cause-specific long-term mortality beyond 30 days in pneumonia. We aimed to compare the mortality of patients with hospitalized pneumonia compared to age- and sex-matched controls beyond 30 days. Participants were drawn from the European Prospective Investigation into Cancer (EPIC)-Norfolk prospective population study. Hospitalized pneumonia cases were identified from record linkage (ICD-10: J12-J18). For this study we excluded people with hospitalized pneumonia who died within 30 days. Each case identified was matched to four controls and followed up until the end June 2012 (total 15 074 person-years, mean 6·1 years, range 0·08-15·2 years). Cox regression models were constructed to examine the all-cause, respiratory and cardiovascular mortality using date of pneumonia onset as baseline with binary pneumonia status as exposure. A total of 2465 men and women (503 cases, 1962 controls) [mean age (s.d.) 64·5 (8·3) years] were included in the study. Between a 30-day to 1-year period, hazard ratios (HRs) of all-cause and cardiovascular mortality were 7·3 [95% confidence interval (CI) 5·4-9·9] and 5·9 (95% CI 3·5-9·7), respectively (with very few respiratory deaths within the same period) in cases compared to controls after adjusting for age, sex, asthma, smoking status, pack years, systolic and diastolic blood pressure, diabetes, physical activity, waist-to-hip ratio, prevalent cardiovascular and respiratory diseases. All outcomes assessed also showed increased risk of death in cases compared to controls after 1 year; respiratory cause of death being the most significant during that period (HR 16·4, 95% CI 8·9-30·1). Hospitalized pneumonia was associated with increased all-cause and specific-cause mortality beyond 30 days. PMID:26300532

    Workers employed in 15 utilities that generate nuclear power in the United States have been followed for up to 18 years between 1979 and 1997. Their cumulative dose from whole-body ionizing radiation has been determined from the dose records maintained by the facilities themselves and the REIRS and REMS systems maintained by the Nuclear Regulatory Commission and the Department of Energy, respectively. Mortality in the cohort from a number of causes has been analyzed with respect to individual radiation doses. The cohort displays a very substantial healthy worker effect, i.e. considerably lower cancer and noncancer mortality than the general population. Based on 26 and 368 deaths, respectively, positive though statistically nonsignificant associations were seen for mortality from leukemia (excluding chronic lymphocytic leukemia) and all solid cancers combined, with excess relative risks per sievert of 5.67 (95% confidence interval (CI) -2.56, 30.4) and 0.596 (95% CI -2.01, 4.64), respectively. These estimates are very similar to those from the atomic bomb survivors study, though the wide confidence intervals are also consistent with lower or higher risk estimates. A strong positive and statistically significant association between radiation dose and deaths from arteriosclerotic heart disease including coronary heart disease was also observed in the cohort, with an ERR of 8.78 (95% CI 2.10, 20.0). Whle associations with heart disease have been reported in some other occupational studies, the magnitude of the present association is not consistent with them and therefore needs cautious interpretation and merits further attention. At present, the relatively small number of deaths and the young age of the cohort (mean age at end of follow-up is 45 years) limit the power of the study, but further follow-up is 45 years) limit the power of the study, but further follow-up and the inclusion of the present data in an ongoing IARC combined analysis of nuclear workers from 15

    The incidence of obstructive sleep apnea (OSA) has reached epidemic proportions, and it is an often unrecognized cause of perioperative morbidity and mortality. Profound hypoxic injury from apnea during the postoperative period is often misdiagnosed as cardiac arrest due to other causes. Almost a quarter of patients entering a hospital for elective surgery have OSA, and >80% of these cases are undiagnosed at the time of surgery. The perioperative period puts patients at high risk of apneic episodes because of drug effects from sedatives, narcotics, and general anesthesia, as well as from the effects of postoperative rapid eye movement sleep changes and postoperative positioning in the hospital bed. For adults, preoperative screening using the STOP or STOP-Bang questionnaires can help to identify adult patients at increased risk of OSA. In the pediatric setting, a question about snoring should be part of every preoperative examination. For patients with known OSA, continuous positive airway pressure should be continued postoperatively. Continuous pulse oximetry monitoring with an alarm system can help to prevent apneic catastrophes caused by OSA in the postoperative period. PMID:26957384

    Background: A geriatric hip fracture clinical pathway, led by an orthopedic surgeon, was developed in 2007. This clinical pathway team is multidisciplinary and consists of surgeons, physicians, anesthetists, nurses, physiotherapists, occupational therapists, medical social workers, dieticians as well as voluntary support groups. Methods: From early 2007 onward, all patients older than 65 years with acute isolated hip fractures were included. During the whole inpatient treatment, all relevant data were captured prospectively. The data in 2006, before the implementation of the clinical pathway, were collected retrospectively through computer record system. A study of the length of stay in acute and rehabilitation hospital and also the short-term mortality rate was carried out to compare the difference before and after the implementation of the pathway. Results: From 2007 onward, more than 1300 hip fractures were treated. After the implementation of the pathway, the preoperative length of stay was markedly shortened by 4 days, from an average of 6.1 days in 2006 to 1.5 days in 2011 (P < .05). The postoperative length of stay and the overall acute hospital length of stay also improved significantly. The length of stay in rehabilitation hospital was also significantly shorter in the 4-year period. Although the number of hip fractures increased annually with increased age and number of comorbidities each year, the inpatient mortality rate showed a gradual decrease from 2.7% in 2006 to 1.25% in 2010. The 30 days mortality rate also showed a decrease from 3.65% in 2006 to 2.75% in 2010. Conclusion: Geriatric hip fracture clinical pathway is an excellent approach to the geriatric hip fracture service. The most significant improvement is the dramatic shortening of the length of hospital stay. Our success in the past 5 years has proven its value and sustainability. PMID:23936733

    One hundred heart surgery patients were followed throughout their postoperative periods to assess the incidence and etiology of postcardiotomy delirium. Factors evaluated were: age, sex, history of previous psychiatric illness, history of cerebrovascular disease, cardiac diagnosis and operation, time of anesthesia, time of bypass, time spent in the intensive-care unit, and amount of sleep during the postoperative period. Six patients developed delirium, five of whom had a lucid postoperative interval; four patients had perceptual disturbances only, without loss of contact with reality; three had neurological symptoms with mild confusion; 87 kept a clear mental state. The following factors tended to be related to the occurrence of delirium and perceptual disturbances: history of preoperative psychiatric illness, advanced age, severity of preoperative and postoperative illness, and time spent in the intensive-care unit. Sleep deprivation consistently preceded onset of these symptoms with one exception. Operative factors did not seem to be of major importance. While postoperative delirium probably has multidetermined causes, the author believes that sleep deprivation superimposed on the other contributory condition is a common precipitating factor. Suggestions about the prevention and treatment of delirium are made. PMID:1177486

    Background Extensive dissemination of carbapenemase-producing Enterobacteriaceae has led to increased resistance among Klebsiella species. Carbapenems are used as a last resort against resistant pathogens, but carbapenemase production can lead to therapy failure. Identification of risk factors for mortality and assessment of current susceptibility breakpoints are valuable for improving patient outcomes. Aim The objective of this study was to evaluate outcomes and risk factors for mortality among patients treated with carbapenems for Klebsiella spp. bacteremia. Methods Patients hospitalized between 2006 and 2012 with blood cultures positive for Klebsiella spp. who received ≥ 48 hours of carbapenem treatment within 72 hours of positive culture were included in this retrospective study. Patient data were retrieved from electronic medical records. Multivariate logistic regression was used to identify risk factors for 30-day hospital mortality. Results One hundred seven patients were included. The mean patient age was 61.5 years and the median APACHE II score was 13 ± 6.2. Overall, 30-day hospital mortality was 9.3%. After adjusting for confounding variables, 30-day mortality was associated with baseline APACHE II score (OR, 1.17; 95% CI, 1.01–1.35; P = 0.03), length of stay prior to index culture (OR, 1.03; 95% CI, 1.00–1.06; P = 0.04), and carbapenem non-susceptible (imipenem or meropenem MIC > 1 mg/L) infection (OR, 9.08; 95% CI, 1.17–70.51; P = 0.04). Conclusions Baseline severity of illness and length of stay prior to culture were associated with 30-day mortality and should be considered when treating patients with Klebsiella bacteremia. These data support the change in carbapenem breakpoints for Klebsiella species. PMID:26618357

    Background Fiscal constraints faced by Medicare are leading to policies designed to reduce expenditures. Evidence of the effect of reduced reimbursement on the mortality of Medicare patients discharged from all major hospital service lines is limited. Methods We modeled risk-adjusted 30-day mortality of patients discharged from 21 hospital service lines as a function of service line profitability, service line time trends, and hospital service line and year-fixed effects. We simulated the effect of alternative revenue-neutral reimbursement policies on mortality. Our sample included all Medicare discharges from PPS-eligible hospitals (1997, 2001, and 2005). Results The results reveal a statistically significant inverse relationship between changes in profitability and mortality. A $0.19 average reduction in profit per $1.00 of costs led to a 0.010–0.020 percentage-point increase in mortality rates (p < .001). Mortality in newly unprofitable service lines is significantly more sensitive to reduced payment generosity than in service lines that remain profitable. Policy simulations that target service line inequities in payment generosity result in lower mortality rates, roughly 700–13,000 fewer deaths nationally. Conclusions The policy simulations raise questions about the trade-offs implicit in universal reductions in reimbursement. The effect of reduced payment generosity on mortality could be mitigated by targeting highly profitable services only for lower reimbursement. PMID:23346946

Data acquired on the make-up of the filtering bleb justifies using postoperative anti-inflammatory drugs, even if the eye is clinically quiet. When using antimetabolites, the risk factors for failure must be well known and either 5-fluorouracile or mitomycin should be chosen depending on the level of risk of scarring. Their use in needle revision must be adapted case by case. anti-TGF-beta-2 antibody, currently being investigated, may prove advantageous in the very near future. PMID:16208245

    BACKGROUND: Recent clinical trials have demonstrated benefit with early revascularization following acute myocardial infarction (AMI). Trends in and the association between early revascularization after (ie, 30 days or fewer) AMI and early death were determined. METHODS AND RESULTS: The Statistics Canada Health Person-Oriented Information Database, consisting of hospital discharge records for seven provinces from the Canadian Institute for Health Information Hospital Morbidity Database, was used. If there was no AMI in the preceding year, the first AMI visit within a fiscal year for a patient 20 years of age or older was included. Times to death in hospital and to revascularization procedures were counted from the admission date of the first AMI visit. Mixed model regression analyses with random slopes were used to assess the relationship between early revascularization and mortality. The overall rate of revascularization within 30 days of AMI increased significantly from 12.5% in 1995 to 37.4% in 2003, while the 30-day mortality rate decreased significantly from 13.5% to 10.6%. There was a linearly decreasing relationship – higher regional use of revascularization was associated with lower mortality in both men and women. CONCLUSIONS: These population-based utilization and outcome findings are consistent with clinical trial evidence of improved 30-day in-hospital mortality with increased early revascularization after AMI.

    Accurate knowledge of a patient’s disease state and trajectory is critical in a clinical setting. Modern electronic healthcare records contain an increasingly large amount of data, and the ability to automatically identify the factors that influence patient outcomes stand to greatly improve the efficiency and quality of care. We examined the use of latent variable models (viz. Latent Dirichlet Allocation) to decompose free-text hospital notes into meaningful features, and the predictive power of these features for patient mortality. We considered three prediction regimes: (1) baseline prediction, (2) dynamic (time-varying) outcome prediction, and (3) retrospective outcome prediction. In each, our prediction task differs from the familiar time-varying situation whereby data accumulates; since fewer patients have long ICU stays, as we move forward in time fewer patients are available and the prediction task becomes increasingly difficult. We found that latent topic-derived features were effective in determining patient mortality under three timelines: inhospital, 30 day post-discharge, and 1 year post-discharge mortality. Our results demonstrated that the latent topic features important in predicting hospital mortality are very different from those that are important in post-discharge mortality. In general, latent topic features were more predictive than structured features, and a combination of the two performed best. The time-varying models that combined latent topic features and baseline features had AUCs that reached 0.85, 0.80, and 0.77 for in-hospital, 30 day post-discharge and 1 year post-discharge mortality respectively. Our results agreed with other work suggesting that the first 24 hours of patient information are often the most predictive of hospital mortality. Retrospective models that used a combination of latent topic features and structured features achieved AUCs of 0.96, 0.82, and 0.81 for in-hospital, 30 day, and 1-year mortality prediction. Our

    Post-operative hyperglycaemia is important with regard to outcomes of surgical operations. It affects post-operative morbidity, length of hospital stay, and mortality. Poor peri-operative blood glucose control leads to a higher risk of post-operative complication. Insulin resistance as a cause of post-operative hyperglycaemia has been blamed for some time. Nitric Oxide (NO) is produced by nitric oxide synthase (NOS) isoenzymes. Inducible nitric oxide synthase (iNOS) is not a normal cellular constitute. It is expressed by cytokines and non-cytokines e.g. fasting, trauma, intravenous glucose, and lipid infusion, which are encountered in surgical operations. Review of current published data on postoperative hyperglycaemia was completed. Our studies and others were explored for the possible role of NO in this scenario. Induction and expression of iNOS enzyme in pancreatic islet cells is included in the chaotic postoperative blood glucose control. The high concentrations of iNOS derived NO are toxic to pancreatic β-cells and may inhibit insulin secretion postoperatively. Hence, current peri-operative management is questionable regarding post-operative hyperglycaemia and necessitates development of a new strategy. PMID:21516149

    Postoperative respiratory failure is related with the highest mortality and morbidity among all perioperative complications. The most common underlying mechanism of postoperative respiratory failure is the development of atelectasis. Anaesthesia, medications which cause respiratory depression, high FiO2 use, postoperative pain and disruption of muscle forces due to surgery leads to decrease in functional residual capacity and results in atelectasis formation. Atelectasis causes severe hypoxemia due to ventilation, perfusion mismatch, shunt and increased peripheral vascular resistance. Intrathoracic positive pressure is an effective therapeutic option in both prevention and treatment of atelectasis. Non-invasive mechanical ventilation is related with a lower mortality and morbidity rate due to lack of any potential complication risks of endotracheal intubation. Non-invasive mechanical ventilation can be applied as prophylactic or curative. Both of these techniques are related with lower reintubation rates, nosocomial infections, duration of hospitalization and mortality in patients with postoperative respiratory failure. The differences of this therapy from standard application and potential complications should be well known in order to improve prognosis in these group of patients. The primary aim of this review is to underline the pathogenesis of postoperative respiratory failure. The secondary aim is to clarify the optimum method, effect and complications of non-invasive mechanical ventilation therapy under the light of the studies which was performed in specific patient groups.

    A total of 12 AFT training sessions were administered to SL 3 Payload Specialists over a 7 month period. Nine of these sessions were 2 hours in duration and three were 3 hours in duration. A total of three rotating chair tests were conducted in this time frame with four subjects. The performance of these crewmen across tests is shown. Test 1, a baseline motion sickness test, was conducted approximately 10 months prior to the mission, before any AFT was administered. Test 2 was administered after 2 hours of AFT, test 3 after 4 hours and test 4 after 6 hours (total) of training in symptom control. Improvement in performance is reflected by a subject's ability to tolerate a greater number of rotations across tests. Additional training for crewman was not possible within the constraints of the mission. Results of the mission indicate that, as predicted preflight, subject #32 was relatively symptom free inflight while subject #33 was not. Other preflight and postflight tests and analyses are reported.

    The Health Services, not only the Italian one, is under pressure because of request for improving treatment quality and the financial need for reorganization and cost-saving. It's required a rationalization of intervention, together with a careful choice of the best and cheapest techniques and the demonstration of their efficacy. The anaesthesia service activity, in a period of cost rationalization and funds restriction should be aimed to appropriate outcome measures corrected by both patient's risk factors and surgical-anaesthesiological case-mix. The development of a complete strategy for surgical pain management might run into two phases. The first phase, internal and mono-specialistic, should develop like the creation of an Acute Pain Team. The main processes are: focusing the problem (charge of the care), training, information, teaching methodology (timing, methods, drugs, techniques, etc.) and the audit (before and after changes). The main aims are the evaluation of the level of analgesia and pain relief or patient's satisfaction which are partial endpoints useful to demonstrate the improvement and the efficacy of the new pain management strategies. The second phase, multidisciplinary, is directed toward the creation of a Postoperative Evaluation Team. The main objective is to set up a collaborative clinical group able to identify the criteria for quality, efficacy and safety. The major purpose is the evaluation of major outcome measures: surgical outcome, morbidity, mortality and length of hospitalization. The improvement in the quality of postoperative pain treatment goes through a better organization and a progressive increase of the already available therapy. The achievement of the result and the quality projects depend on the interaction among staff members with different behaviours and settings.

    Colorectal surgery patients frequently suffer from postoperative complications. Patients with complications have been shown to be at higher risk for mortality, poor oncologic outcomes, additional complications, and worse quality of life. Complications are increasingly recognized as markers of quality of care with more use of risk-adjusted national surgical databases and increasing transparency in health care. Quality improvement work in colorectal surgery has identified methods to decrease complication rates and improve outcomes in this patient population. Future work will continue to identify best practices and standardized ways to measure quality of care. PMID:27582650

    It is known that mortality of Jews is different from the mortality of the populations that surround them. However, the existence of commonalities in mortality of different Jewish communities across the world has not received scholarly attention. This paper aims to identify common features of the evolution of Jewish mortality among Jews living in Israel and the Diaspora. In the paper the mortality of Jews in Israel is systematically compared with the mortality of the populations of developed countries, and the findings from the earlier studies of mortality of Jews in selected Diaspora communities are re-examined. The outcome is a re-formulation and extension of the notion of the 'Jewish pattern of mortality'. The account of this pattern is based on the consistently low level of behaviourally induced mortality, the migration history of Jewish populations and the enduring influence of early-life conditions on mortality at older ages.

    We examined temporal trends in mortality after myocardial infarction from 1985 to 2008 depending on admission glucose levels. We included 11,324 consecutive patients admitted to our intensive coronary care unit for myocardial infarction from 1985 to 2008. Patients were categorized into normal, mild, and severe hyperglycemia groups (admission glucose levels <140, 140 to 200, and ≥200 mg/dl, respectively). Temporal trends were determined using 3 groups: 1985 to 1990, 1990 to 2000, and 2000 to 2008. The prevalence of hyperglycemia increased from 26% in the 1980s to 49% in the 2000s. The prevalence of hyperglycemia primarily increased in patients without diabetes. Kaplan-Meier mortality was 4%, 8%, and 17% at 30 days and 64%, 71%, and 82% at 20 years in patients with normal, mild, and severe hyperglycemia, respectively. Compared with normal admission glucose level, adjusted 30-day mortality was 3.6-fold greater (95% confidence interval 2.9 to 4.3) in patients with severe hyperglycemia. This association was not dependent on diabetic status (p for interaction = 0.43) but was dependent on the decade of hospitalization with a stronger association from 2000 to 2008 (adjusted odds ratio 7.7, 95% confidence interval 5.4 to 11, p for interaction <0.001). Compared with diabetes, hyperglycemia was a better discriminator for 30-day mortality. Mortality at 30 days decreased from 1985 to 2008, however, it decreased less in patients with hyperglycemia compared with those with normoglycemia. In conclusion, elevated admission glucose levels are common in patients with myocardial infarction and are strongly associated with increased mortality. Mortality decreased less from 1985 to 2008 in patients with hyperglycemia compared with those with normoglycemia. Efforts that establish optimal treatment for these patients remain warranted.

    Purpose This study aimed to examine extended postoperative ileus and its risk factors in patients who have undergone abdominal surgery, and discuss the techniques of prevention and management thereof the light of related risk factors connected with our study. Methods This prospective study involved 103 patients who had undergone abdominal surgery. The effects of age, gender, diagnosis, surgical operation conducted, excessive small intestine manipulation, opioid analgesic usage time, and systemic inflammation on the time required for the restoration of intestinal motility were investigated. The parameters were investigated prospectively. Results Regarding the factors that affected the restoration of gastrointestinal motility, resection operation type, longer operation period, longer opioid analgesics use period, longer nasogastric catheter use period, and the presence of systemic inflammation were shown to retard bowel motility for 3 days or more. Conclusion Our study confirmed that unnecessary analgesics use in patients with pain tolerance with non-steroid anti-inflammatory drugs, excessive small bowel manipulation, prolonged nasogastric catheter use have a direct negative effect on gastrointestinal motility. Considering that an exact treatment for postoperative ileus has not yet been established, and in light of the risk factors mentioned above, we regard that prevention of postoperative ileus is the most effective way of coping with intestinal dysmotility.

    Endovascular aneurysm repair (EVAR) is an advanced minimally invasive surgical technology that is helpful for reducing patients' recovery time, postoperative morbidity and mortality. This study proposes an ensemble model to predict postoperative morbidity after EVAR. The ensemble model was developed using a training set of consecutive patients who underwent EVAR between 2000 and 2009. All data required for prediction modeling, including patient demographics, preoperative, co-morbidities, and complication as outcome variables, was collected prospectively and entered into a clinical database. A discretization approach was used to categorize numerical values into informative feature space. Then, the Bayesian network (BN), artificial neural network (ANN), and support vector machine (SVM) were adopted as base models, and stacking combined multiple models. The research outcomes consisted of an ensemble model to predict postoperative morbidity after EVAR, the occurrence of postoperative complications prospectively recorded, and the causal effect knowledge by BNs with Markov blanket concept.

    Background Predicting mortality in patients undergoing transcatheter aortic valve implantation (TAVI) remains a challenge. Objectives To evaluate the performance of 5 risk scores for cardiac surgery in predicting the 30-day mortality among patients of the Brazilian Registry of TAVI. Methods The Brazilian Multicenter Registry prospectively enrolled 418 patients undergoing TAVI in 18 centers between 2008 and 2013. The 30-day mortality risk was calculated using the following surgical scores: the logistic EuroSCORE I (ESI), EuroSCORE II (ESII), Society of Thoracic Surgeons (STS) score, Ambler score (AS) and Guaragna score (GS). The performance of the risk scores was evaluated in terms of their calibration (Hosmer–Lemeshow test) and discrimination [area under the receiver–operating characteristic curve (AUC)]. Results The mean age was 81.5 ± 7.7 years. The CoreValve (Medtronic) was used in 86.1% of the cohort, and the transfemoral approach was used in 96.2%. The observed 30-day mortality was 9.1%. The 30-day mortality predicted by the scores was as follows: ESI, 20.2 ± 13.8%; ESII, 6.5 ± 13.8%; STS score, 14.7 ± 4.4%; AS, 7.0 ± 3.8%; GS, 17.3 ± 10.8%. Using AUC, none of the tested scores could accurately predict the 30-day mortality. AUC for the scores was as follows: 0.58 [95% confidence interval (CI): 0.49 to 0.68, p = 0.09] for ESI; 0.54 (95% CI: 0.44 to 0.64, p = 0.42) for ESII; 0.57 (95% CI: 0.47 to 0.67, p = 0.16) for AS; 0.48 (95% IC: 0.38 to 0.57, p = 0.68) for STS score; and 0.52 (95% CI: 0.42 to 0.62, p = 0.64) for GS. The Hosmer–Lemeshow test indicated acceptable calibration for all scores (p > 0.05). Conclusions In this real world Brazilian registry, the surgical risk scores were inaccurate in predicting mortality after TAVI. Risk models specifically developed for TAVI are required.

    Small Bowel obstruction due to post-operative adhesions is a common problem in a general surgical practice. Any laparotomy initiates the lifelong risk of this complication. Mortality rates have improved dramatically in the last three decades. The basic evaluation and treatment of small bowel obstruction is well defined but many individual strategies may result from the variety of clinical presentations and from techniques and equipment available to a local surgical practice. Recent advances in surgical techniques and preventive strategies may improve overall results. Results will remain linked to the continuous aging of the populations of Western countries.

    While deep sternal wound infection (DSWI) after cardiac surgery is a significant contributor to patient morbidity and mortality, superficial sternal wound infection (SSWI) mostly has a benign course. We report a mortality case of aortic rupture resulting from SSWI after cardiac surgery. A 50-year-old male underwent an aortic valve replacement (AVR). Three months after the valve operation, he presented with severe dyspnea, which had never before been observed, and chest computed tomography revealed an ascending aortic rupture with large hematoma compressing the main pulmonary artery. We performed an emergent operation for aortic rupture that possibly originated from the SSWI. Postoperatively, the patient died of hypovolemic shock due to recurrent aortic rupture despite efforts to resuscitate him. PMID:27499988

    Mortality tables play important role in actuarial studies such as life annuities, premium determination, premium reserve, valuation pension plan, pension funding. Some known mortality tables are CSO mortality table, Indonesian Mortality Table, Bowers mortality table, Japan Mortality table. For actuary applications some tables are constructed with different environment such as single decrement, double decrement, and multiple decrement. There exist two approaches in mortality table construction : mathematics approach and statistical approach. Distribution model and estimation theory are the statistical concepts that are used in mortality table construction. This article aims to discuss the statistical approach in mortality table construction. The distributional assumptions are uniform death distribution (UDD) and constant force (exponential). Moment estimation and maximum likelihood are used to estimate the mortality parameter. Moment estimation methods are easier to manipulate compared to maximum likelihood estimation (mle). However, the complete mortality data are not used in moment estimation method. Maximum likelihood exploited all available information in mortality estimation. Some mle equations are complicated and solved using numerical methods. The article focus on single decrement estimation using moment and maximum likelihood estimation. Some extension to double decrement will introduced. Simple dataset will be used to illustrated the mortality estimation, and mortality table.

    Background Whether heart rate upon discharge following hospitalization for heart failure is associated with long‐term adverse outcomes and whether this association differs between patients with sinus rhythm (SR) and atrial fibrillation (AF) have not been well studied. Methods and Results We conducted a retrospective cohort study from clinical registry data linked to Medicare claims for 46 217 patients participating in Get With The Guidelines®–Heart Failure. Cox proportional‐hazards models were used to estimate the association between discharge heart rate and all‐cause mortality, all‐cause readmission, and the composite outcome of mortality/readmission through 1 year. For SR and AF patients with heart rate ≥75, the association between heart rate and mortality (expressed as hazard ratio [HR] per 10 beats‐per‐minute increment) was significant at 0 to 30 days (SR: HR 1.30, 95% CI 1.22 to 1.39; AF: HR 1.23, 95% CI 1.16 to 1.29) and 31 to 365 days (SR: HR 1.15, 95% CI 1.12 to 1.20; AF: HR 1.05, 95% CI 1.01 to 1.08). Similar associations between heart rate and all‐cause readmission and the composite outcome were obtained for SR and AF patients from 0 to 30 days but only in the composite outcome for SR patients over the longer term. The HR from 0 to 30 days exceeded that from 31 to 365 days for both SR and AF patients. At heart rates <75, an association was significant for mortality only for both SR and AF patients. Conclusions Among older patients hospitalized with heart failure, higher discharge heart rate was associated with increased risks of death and rehospitalization, with higher risk in the first 30 days and for SR compared with AF.

    Objective Controversy exists over the utility of early post-operative magnetic resonance imaging (MRI) after transsphenoidal pituitary surgery for macroadenomas. We investigate whether valuable information can be derived from current higher resolution scans. Methods Volumetric MRI scans were obtained in the early (<10 days) and late (>30 days) post-operative periods in a series of patients undergoing transsphenoidal pituitary surgery. The volume of the residual tumor, resection cavity, and corresponding visual field tests were recorded at each time point. Statistical analyses of changes in tumor volume and cavity size were calculated using the late MRI as the gold standard. Results 40 patients met the inclusion criteria. Pre-operative tumor volume averaged 8.8 cm3. Early postoperative assessment of average residual tumor volume (1.18 cm3) was quite accurate and did not differ statistically from late post-operative volume (1.23 cm3, p=.64), indicating the utility of early scans to measure residual tumor. Early scans were 100% sensitive and 91% specific for predicting ≥ 98% resection (p<.001, Fisher’s exact test). The average percent decrease in cavity volume from pre-operative MRI (tumor volume) to early post-operative imaging was 45% with decreases in all but 3 patients. There was no correlation between the size of the early cavity and the visual outcome. Conclusions Early high resolution volumetric MRI is valuable in determining the presence or absence of residual tumor. Cavity volume almost always decreases after surgery and a lack of decrease should alert the surgeon to possible persistent compression of the optic apparatus that may warrant re-operation.

    A matched-propensity analysis of national data from the British Thoracic Society community-acquired pneumonia audit was conducted (n=13 725). Overall, time to first antibiotic (TFA) was ≤4 h in 63%. Adjusted 30-day inpatient (IP) mortality was lower for adults with TFA ≤4 h compared with TFA >4 h (adjusted OR 0.84, 95% CI 0.74 to 0.94; p=0.003). Increasing TFA was associated with greater OR of 30-day IP mortality (p value for trend=0.001), but no TFA threshold was evident. Although we found an association between TFA and mortality, we cannot say whether this is causal or whether TFA might just be a quality measure for overall or other processes of care. PMID:26559161

    In the post-operative course of the interventions of lung resection for primary tumor, complications of different nature and severity can arise, recognizing different pathogenetic mechanisms and differing according to the type of resection performed and to the time elapsed after surgery. The low diagnostic accuracy of chest radiography requires a thorough knowledge of the radiologist about all radiographic findings, both normal and pathological, which can be found in the immediate post-operative period (within 30 days after surgery). This article aims to describe the incidence, the clinical features and the radiological aspects of immediate complications following pulmonary resections, with specific reference to those in which the diagnostic imaging provides a fundamental contribution.

    Objective Mortality in heart failure (AHF) remains high, especially during the first days of hospitalization. New prognostic biomarkers may help to optimize treatment. The aim of the study was to determine metabolites that have a high prognostic value. Methods We conducted a prospective study on a training cohort of AHF patients (n = 126) admitted in the cardiac intensive care unit and assessed survival at 30 days. Venous plasmas collected at admission were used for 1H NMR–based metabonomics analysis. Differences between plasma metabolite profiles allow determination of discriminating metabolites. A cohort of AHF patients was subsequently constituted (n = 74) to validate the findings. Results Lactate and cholesterol were the major discriminating metabolites predicting 30-day mortality. Mortality was increased in patients with high lactate and low total cholesterol concentrations at admission. Accuracies of lactate, cholesterol concentration and lactate to cholesterol (Lact/Chol) ratio to predict 30-day mortality were evaluated using ROC analysis. The Lact/Chol ratio provided the best accuracy with an AUC of 0.82 (P < 0.0001). The acute physiology and chronic health evaluation (APACHE) II scoring system provided an AUC of 0.76 for predicting 30-day mortality. APACHE II score, Cardiogenic shock (CS) state and Lact/Chol ratio ≥ 0.4 (cutoff value with 82% sensitivity and 64% specificity) were significant independent predictors of 30-day mortality with hazard ratios (HR) of 1.11, 4.77 and 3.59, respectively. In CS patients, the HR of 30-day mortality risk for plasma Lact/Chol ratio ≥ 0.4 was 3.26 compared to a Lact/Chol ratio of < 0.4 (P  =  0.018). The predictive power of the Lact/Chol ratio for 30-day mortality outcome was confirmed with the independent validation cohort. Conclusion This study identifies the plasma Lact/Chol ratio as a useful objective and simple parameter to evaluate short term prognostic and could be integrated into quantitative

    The role of linezolid in empirical therapy of suspected bacteremia remains unclear. The aim of this study was to evaluate the influence of empirical use of linezolid or glycopeptides in addition to other antibiotics on the 30-day mortality rates in patients with Gram-negative bacteremia. For this purpose, 1,126 patients with Gram-negative bacteremia in the Hospital Clinic of Barcelona from 2000 to 2012 were included in this study. In order to compare the mortality rates between patients who received linezolid or glycopeptides, the propensity scores on baseline variables were used to balance the treatment groups, and both propensity score matching and propensity-adjusted logistic regression were used to compare the 30-day mortality rates between the groups. The overall 30-day mortality rate was 16.0% during the study period. Sixty-eight patients received empirical treatment with linezolid, and 1,058 received glycopeptides. The propensity score matching included 64 patients in each treatment group. After matching, the mortality rates were 14.1% (9/64) in patients who received glycopeptides and 21.9% (14/64) in those who received linezolid, and a nonsignificant association between empirical linezolid treatment and mortality rate (odds ratio [OR], 1.63; 95% confidence interval [CI], 0.69 to 3.82; P = 0.275, McNemar's test) was found. This association remained nonsignificant when variables that remained unbalanced after matching were included in a conditional logistic regression model. Further, the stratified propensity score analysis did not show any significant relationship between empirical linezolid treatment and the mortality rate after adjustment by propensity score quintiles or other variables potentially associated with mortality. In conclusion, the propensity score analysis showed that empirical treatment with linezolid compared with that with glycopeptides was not associated with 30-day mortality rates in patients with Gram-negative bacteremia.

    A 72-year-old man, smoker, with insuline-dependent diabetes and dislipemia underwent left pneumonectomy. Several episodes of intraoperative hemodynamic instability associated with electrocardiographic ST segment alterations were attributed to surgical manipulation; ischemia was not suspected. Cardiorespiratory failure, related to extensive anterior infarction, developed a few minutes after admission to the postoperative intensive care unit (PICU). Cardiopulmonary resuscitation and mechanical ventilation were required. The patient responded to treatment with beta blockers, platelet antiaggregants and statins. Tube was removed a few hours later and the patient was discharged from the PICU on the fifth day. Pneumonectomy has a high rate of morbidity and mortality, with complications mainly arising in the lung and heart. Risk from anesthesia is considered to be great in this procedure, and for that reason it is essential to identify intraoperative myocardial ischemia so that it can be treated aggressively. In patients at high cardiovascular risk who undergo lung resection, intraoperative episodes of myocardial ischemia are associated with a high incidence of postoperative miocardial infarction. Therefore, careful postoperative monitoring is needed and measures should be taken to prevent angina. Early extubation should be avoided. PMID:12516493

    BACKGROUND Healthcare provider hands are an important source of intraoperative bacterial transmission events associated with postoperative infection development. OBJECTIVE To explore the efficacy of a novel hand hygiene improvement system leveraging provider proximity and individual and group performance feedback in reducing 30-day postoperative healthcare-associated infections via increased provider hourly hand decontamination events. DESIGN Randomized, prospective study. SETTING Dartmouth-Hitchcock Medical Center in New Hampshire and UMass Memorial Medical Center in Massachusetts. PATIENTS Patients undergoing surgery. METHODS Operating room environments were randomly assigned to usual intraoperative hand hygiene or to a personalized, body-worn hand hygiene system. Anesthesia and circulating nurse provider hourly hand decontamination events were continuously monitored and reported. All patients were followed prospectively for the development of 30-day postoperative healthcare-associated infections. RESULTS A total of 3,256 operating room environments and patients (1,620 control and 1,636 treatment) were enrolled. The mean (SD) provider hand decontamination event rate achieved was 4.3 (2.9) events per hour, an approximate 8-fold increase in hand decontamination events above that of conventional wall-mounted devices (0.57 events/hour); P<.001. Use of the hand hygiene system was not associated with a reduction in healthcare-associated infections (odds ratio, 1.07 [95% CI, 0.82-1.40], P=.626). CONCLUSIONS The hand hygiene system evaluated in this study increased the frequency of hand decontamination events without reducing 30-day postoperative healthcare-associated infections. Future work is indicated to optimize the efficacy of this hand hygiene improvement strategy. Infect Control Hosp Epidemiol 2016;37:888-895. PMID:27267310

    Elderly people represent the fastest-growing segment of our society and undergo surgery more frequently than other age groups. Effective postoperative analgesia is essential in these patients because inadequate pain control after surgery is associated with adverse outcomes in elderly patients. However, management of postoperative pain in older patients may be complicated by a number of factors, including a higher risk of age- and disease-related changes in physiology and disease-drug and drug-drug interactions. Physiological changes related to aging need to be carefully considered because aging is individualized and progressive. Assessment of pain management needs to include chronological age, biological age with regard to renal, liver and cardiac functions, and the individual profile of pathology and prescribed medications. In addition, ways in which pain should be assessed, particularly in patients with cognitive impairment, must be considered. Cognitively intact older patients can use most commonly used unidimensional pain scales such as the visual analogue scale (VAS), verbal rating scale (VRS), numeric rating scale (NRS) and facial pain scale (FPS). VRS and NRS are the most appropriate pain scales for the elderly. In older patients with mild to moderate cognitive impairment, the VRS is a better tool. For severe cognitively impaired older patients, behavioural scales validated in the postoperative context, such as Doloplus-2 or Algoplus, are appropriate. For postoperative pain treatment, most drugs (e.g. paracetamol, nonsteroidal anti-inflammatory drugs, nefopam, tramadol, codeine, morphine, local anaesthetics), techniques (e.g. intravenous morphine titration, subcutaneous morphine, intravenous or epidural patient-controlled analgesia, intrathecal morphine, peripheral nerve block) and strategies (e.g. anticipated intraoperative analgesia or multimodal analgesia) used for acute pain management can be used in older patients. However, in view of pharmacokinetic

    Background and purpose - Historically, high 30-day and 1-year mortality post-amputation rates (> 30% and 50%, respectively) have been reported in patients with a transtibial or higher non-traumatic lower extremity amputation (LEA). We evaluated whether allocating experienced staff and implementing an enhanced, multidisciplinary recovery program would reduce the mortality rates. We also determined factors that influenced mortality rates. Patients and methods - 129 patients with a LEA were consecutively included over a 2-year period, and followed after admission to an acute orthopedic ward. Mortality was compared with historical and concurrent national controls in Denmark. Results - The 30-day and 1-year mortality rates were 16% and 37%, respectively, in the intervention group, as compared to 35% and 59% in the historical control group treated in the same orthopedic ward. Cox proportional harzards models adjusted for age, sex, residential and health status, the disease that caused the amputation, and the index amputation level showed that 30-day and 1-year mortality risk was reduced by 52% (HR =0.48, 95% CI: 0.25-0.91) and by 46% (HR =0.54, 95% CI: 0.35-0.86), respectively, in the intervention group. The risk of death was increased for patients living in a nursing home, for patients with a bilateral LEA, and for patients with low health status. Interpretation - With similarly frail patient groups and instituting an enhanced program for patients after LEA, the risks of death by 30 days and by 1 year after LEA were markedly reduced after allocating staff with expertise.

    A 55-year-old man suffered from blurred vision of the left eye (visual acuity was counting fingers/5-10 cm) 8 days after undergoing cataract surgery. After thorough ophthalmologic examinations with gram-negative bacillus justified on smear of vitreous specimen, postoperative endophthalmitis (os) was impressed. Intravitreous injection of 1.0 mg of vancomycin, 0.4 mg of amikacin, and 0.4 mg of dexamethasone was given twice and vitreous fluid culture was also performed. However, the inflammatory condition was not well controlled. Because the results of vitreous fluid culture revealed Flavimonas oryzihabitans infection which is sensitive to piperacillin, we performed the 3rd intravitreous injection of 1.0 mg of piperacillin and 0.4 mg of dexamethasone. The inflammatory condition was under control and the visual acuity of left eye improved. For patients with ocular diseases, postoperative endophthalmitis by Flavimonas oryzihabitans is a rare condition. According to the results of this case, intravitreous injection of piperacillin was effective against the pathogen. PMID:15796259

    Between 10 and 40% of patients who have undergone a radical prostatectomy may have a biologic recurrence. Local or distant failure represents the possible patterns of relapse. Patients at high-risk for local relapse have extraprostatic disease, positive surgical margins or seminal vesicles infiltration or high Gleason score at pathology. Three phase-III randomized clinical trials have shown that, for these patients, adjuvant irradiation reduces the risk of tumoral progression without higher toxicity. Salvage radiotherapy for late relapse allows a disease control in 60-70% of the cases. Several research in order to improve the therapeutic ratio of the radiotherapy after prostatectomy are evaluate in the French Groupe d'Étude des Tumeurs Urogénitales (Gétug) and of the French association of urology (Afu). The Gétug-Afu 17 trial will provide answers to the question of the optimal moment for postoperative radiotherapy for pT3-4 R1 pN0 Nx patients, with the objective of comparing an immediate treatment to a differed early treatment initiated at biological recurrence. The Gétug-Afu 22 questions the place of a short hormonetherapy combined with image-guided, intensity-modulated radiotherapy (IMRT) in adjuvant situation for a detectable prostate specific antigen (PSA). The implementation of a multicenter quality control within the Gétug-Afu in order to harmonize a modern postoperative radiotherapy will allow the development of a dose escalation IMRT after surgery.

    Acinetobacter baumannii can cause a serious infection in solid-organ transplant (SOT) recipients, and more data on A. baumannii infection is needed. We sought to investigate the epidemiology and distribution of A. baumannii isolates in SOT recipients. We also investigated the risk factors for overall in-hospital mortality and infection-related 30-day mortality using multivariate logistic regression analysis. A double-center retrospective study of SOT recipients who were infected with A. baumannii between January 2003 and January 2015 was conducted. A total of 71 individuals developed 93 episodes of A. baumannii infection, with a mean age of 44.5 years (44.5±11.9 years). Ninety percent of recipients had nosocomial origin A. baumannii infection, with the bloodstream as the most common site of infection (32.4%). Septic shock developed in 23.9% (17 of 71) of all recipients with A. baumannii infection. Morbidity and mortality rates of A. baumannii infections were high in SOT recipients. The incidence rate of A. baumannii infection in SOT recipients was 3.9% (71 of 1,821). Overall in-hospital mortality and infection-related 30-day mortality were 53.5% (38 of 71) and 40.8% (29 of 71), respectively. Risk factors independently associated with overall in-hospital mortality were mechanical ventilation at onset of A. baumannii infection (odds ratio [OR] 6.29, 95% confidence interval [CI] 1.48-26.85; P=0.013), liver or liver-kidney transplantation (OR 15.33, 95% CI 1.82-129.18; P=0.012), and late-onset A. baumannii infection (OR 7.61, 95% CI 1.07-54.36; P=0.043). A platelet count <50,000/mm(3) (OR 12.76, 95% CI 1.28-126.81; P=0.030) and mechanical ventilation at onset of A. baumannii infection (OR 189.98, 95% CI 13.23-2,728.81; P<0.001) were identified as independent risk factors for infection-related 30-day mortality. In conclusion, the morbidity and mortality rates of A. baumannii infections were high in SOT recipients. Mechanical ventilation at onset of A. baumannii

    Mexico's crude death rate has declined from 33/1000 in the early 20th century to about 6/1000 in 1985-87. Mortality declined sharply from 1640-60. more slowly from 1960-77, and rapidly again beginning around 1980. The explanation for the mortality decline lies both in advances in medical and health care and in economic growth of the country. The mortality declines in the late 1970s and early 1980s probably resulted primarily from extension of primary health care programs in rural areas. The infant mortality rate has declined from 288.6/1000 live births in 1900 to 73.8 in 1960 and 42 in 1986-87. At present 30% of deaths in Mexico are to children under 5, but little is known of the impact of the country's economic crisis on mortality in this age group. The strong mortality decline between 1950-70 was in the economically active age group of 15-64 years. Excess male mortality in this group reached a maximum in 1980: for each death of woman there were 150 male deaths. Between 1960-80 the rate of deaths due to infection, parasfitism, and respiratory disease declined by 5%, the rate of death from cancer remained almost unchanged, and the rate of death from cardiovascular diseases increased by 9%. Deaths from accidents, homicide, suicide, and other violence increased by 38%. Male general mortality rates were 25% higher than female in 1980. Mexican life expectancy increased from 49.6 years in 195 to 67 in 1987. Life expectancy was 65.6 for males and 71.7 for females. Average life expectancy was 69 for the more privileged social sectors and 56.7 for agricultural workers in 1965-79. The life expectancy of urban women was 3 years longer than that of rural women and 10.4 years longer than that of rural men. PMID:12158030

    A case-study involving 56 randomly selected beef herds in Alberta was conducted to assess the association of a number of suspected risk factors upon the odds of a high mortality from diarrhea among calves less than 30 days of age. Using stepwise logistic regression it was found that an increased percentage of heifers calving in the herd, poor drainage in the nursing area, providing limited shelter in the nursing area, a large calving area, and wintering cows and heifers on the same ground were conditionally associated with an increase in the odds of high mortality from neonatal diarrhea.

    Objective: To determine trends in incidence and mortality of intracerebral hemorrhage (ICH) in a rigorous population-based study. Methods: We identified all cases of spontaneous ICH in a South Texas community from 2000 to 2010 using rigorous case ascertainment methods within the Brain Attack Surveillance in Corpus Christi Project. Yearly population counts were determined from the US Census, and deaths were determined from state and national databases. Age-, sex-, and ethnicity-adjusted incidence was estimated for each year with Poisson regression, and a linear trend over time was investigated. Trends in 30-day case fatality and long-term mortality (censored at 3 years) were estimated with log-binomial or Cox proportional hazards models adjusted for demographics, stroke severity, and comorbid disease. Results: A total of 734 cases of ICH were included. The age-, sex-, and ethnicity-adjusted ICH annual incidence rate was 5.21 per 10,000 (95% confidence interval [CI] 4.36, 6.24) in 2000 and 4.30 per 10,000 (95% CI 3.21, 5.76) in 2010. The estimated 10-year change in demographic-adjusted ICH annual incidence rate was −31% (95% CI −47%, −11%). Yearly demographic-adjusted 30-day case fatality ranged from 28.3% (95% CI 19.9%, 40.3%) in 2006 to 46.5% (95% CI 35.5, 60.8) in 2008. There was no change in ICH case fatality or long-term mortality over time. Conclusions: ICH incidence decreased over the past decade, but case fatality and long-term mortality were unchanged. This suggests that primary prevention efforts may be improving over time, but more work is needed to improve ICH treatment and reduce the risk of death. PMID:24838789

    Epidemiologic evidence suggested chronic obstructive pulmonary disease (COPD) might increase risk for abdominal aortic aneurysm (AAA). However, the association between COPD and AAA remains inconclusive. We searched PubMed and Cochrane databases until June 2015. Forty-eight articles were included for meta-analysis. COPD was found to be positively associated with AAA, regardless of study design and smoking status. AAA mortality is higher among COPD patients compared with non-COPD patients (postoperative [adjusted OR 2.11; 95% CI 1.33-3.34]; long-term [adjusted OR 1.70; 95% CI 1.37-2.12]). But the association between postoperative mortality and COPD was not found to be significant in patients underwent endovascular aneurysm repair (mixed OR 2.53; 95% CI 0.70-9.18). Rupture AAA may increase the postoperative mortality in COPD patients (rupture [adjusted OR 4.75; 95% CI 2.07-10.89]; non-rupture [adjusted OR 1.97; 95% CI 1.11-3.49]). The AAA postoperative morbidity was found to be positively associated with COPD (adjusted OR 1.59; 95% CI 1.14-2.21). Increased COPD severity may increase the long-term mortality (medical versus oxygen dependent: [OR 1.26; 95% CI 1.07-1.49] versus [OR 2.79; 95% CI 2.24-3.49]). In conclusion, COPD may increase the risk of AAA, morbidity and mortality of AAA patients underwent endovascular aortic repair. PMID:27112336

    Hip fracture patients represent a large part of the elderly surgical population and face severe postoperative morbidity and excessive mortality compared to adult surgical hip fracture patients. Low antioxidant status and taurine deficiency is common in the elderly, and may negatively affect postoperative outcome. We hypothesized that taurine, an antioxidant, could improve clinical outcome in the elderly hip fracture patient. A double blind randomized, placebo controlled, clinical trial was conducted on elderly hip fracture patients. Supplementation started after admission and before surgery up to the sixth postoperative day. Markers of oxidative status were measured during hospitalization, and postoperative outcome was monitored for one year after surgery. Taurine supplementation did not improve in-hospital morbidity, medical comorbidities during the first year, or mortality during the first year. Taurine supplementation lowered postoperative oxidative stress, as shown by lower urinary 8-hydroxy-2-deoxyguanosine levels (Generalized estimating equations (GEE) analysis average difference over time; regression coefficient (Beta): −0.54; 95% CI: −1.08–−0.01; p = 0.04), blunted plasma malondialdehyde response (Beta: 1.58; 95% CI: 0.00–3.15; p = 0.05) and a trend towards lower lactate to pyruvate ratio (Beta: −1.10; 95% CI: −2.33–0.12; p = 0.08). We concluded that peri-operative taurine supplementation attenuated postoperative oxidative stress in elderly hip fracture patients, but did not improve postoperative morbidity and mortality.

    Postoperative anxiety has received less attention historically than preoperative anxiety. Recognition that anxiety occurs throughout the perioperative period has led to increased interest in identifying and treating anxiety in the postoperative period. This article outlines the causes of postoperative anxiety, how it is classified, the effects of anxiety on outcomes after surgery, and some of the clinical procedures that produce the highest levels of anxiety for patients. In addition, an attempt is made to delineate the major risk factors for developing postoperative anxiety and the classic therapeutic modalities used to reduce symptoms and treat the psychological manifestations of anxiety.

    Abstract Cancer is currently in the spotlight due to their heavy responsibility as main cause of death in both developed and developing countries. Analysis of the epidemiological situation is required as a support tool for the planning of public health measures for the most vulnerable groups. We analyzed cancer mortality trends in Brazil and geographic regions in the period 1996 to 2010 and calculate mortality predictions for the period 2011 to 2030. This is an epidemiological, demographic-based study that utilized information from the Mortality Information System on all deaths due to cancer in Brazil. Mortality trends were analyzed by the Joinpoint regression, and Nordpred was utilized for the calculation of predictions. Stability was verified for the female (annual percentage change [APC] = 0.4%) and male (APC = 0.5%) sexes. The North and Northeast regions present significant increasing trends for mortality in both sexes. Until 2030, female mortality trends will not present considerable variations, but there will be a decrease in mortality trends for the male sex. There will be increases in mortality rates until 2030 for the North and Northeast regions, whereas reductions will be verified for the remaining geographic regions. This variation will be explained by the demographic structure of regions until 2030. There are pronounced regional and sex differences in cancer mortality in Brazil, and these discrepancies will continue to increase until the year 2030, when the Northeast region will present the highest cancer mortality rates in Brazil.

    Aim: To compare the effect of honey, chlorhexidine mouthwash and combination of xylitol chewing gum and chlorhexidine mouthwash on the dental plaque level. Materials and Methods: Ninety healthy dental students, both male and female, aged between 21 to 25 years participated in the study. The subjects were randomly divided into three groups, i.e. the honey group, the chlorhexidine gluconate mouthwash group and the combination of xylitol chewing gum and chlorhexidine (CHX) mouthwash group. The data was collected at the baseline, 15th day and 30th day; the plaque was disclosed using disclosing solution and their scores were recorded at six sites per tooth using the Quigley and Hein plaque index modified by Turesky-Gilmore-Glickman. Statistical analysis was carried out later to compare the effect of all the three groups. P ≤ 0.05 was considered as statistically significant. Results: Our result showed that all the three groups were effective in reducing the plaque but post-hoc LSD (Least Significant Difference) showed that honey group and chlorhexidine + xylitol group were more effective than chlorhexidine group alone. The results demonstrated a significant reduction of plaque indices in honey group and chlorhexidine + xylitol group over a period of 15 and 30 days as compared to chlorhexidine. PMID:25657903

    Background/Aims: The aim of this study was to compare the efficacy of terlipressin versus somatostatin as adjuvants to endoscopic treatment in cirrhotic patients with gastric variceal bleeding. Patients and Methods: The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to enroll patients who were discharged with International Classification of Diseases, 9th Revision, Clinical Modification diagnoses of cirrhosis and who underwent gastric variceal sclerotherapy for gastric variceal bleeding between January 1, 2007, and December 31, 2007. We observed treatment outcomes and identified clinical factors associated with mortality. Results: In total, we enrolled 311 cirrhosis patients who underwent sclerotherapy for active gastric variceal bleeding. Among them, 218 patients received terlipressin, and 93 patients received somatostatin. The overall 30 day mortality rate was 13.2% (41/311). A total of 78 (25.1%) patients underwent second-look endoscopy, but only 12 (7%) needed a second course of gastric variceal sclerotherapy. The overall 30-day mortality rates for patients treated with terlipressin and somatostatin were 13.3% and 12.9%, respectively, showing no statistically significant differences between outcomes in the two treatment groups (P = 0.672). The risk of 30-day mortality was significantly higher in patients with hepatocellular carcinoma (HR: 3.257, 95% CI: 1.640-6.469, P= 0.001), acute renal failure (HR: 6.261, 95% CI: 2.376-16.499, P < 0.001), or hepatic encephalopathy (HR: 3.091, 95% CI: 1.430-6.680, P= 0.004). Conclusions: Mortality rates did not differ significantly between cirrhosis patients with acute gastric variceal bleeding who received somatostatin or terlipressin as adjuvants to endoscopy.

    It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, “ossified” knowledge or modalities really prove themselves in the literature? Could questions such as “is postoperative brace use really necessary?”, “what are the benefits of early restoration of the range of motion (ROM)?”, “to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?”, “how early can proprioception training and open chain exercises begin?”, “should strengthening training start in the immediate postoperative period?” be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

    Using hospital discharge abstract data for fiscal year 1984 for all acute care hospitals treating Medicare patients (age greater than or equal to 65), we measured four mortality rates: inpatient deaths, deaths within 30 days after discharge, and deaths within two fixed periods following admission (30 days, and the 95th percentile length of stay for each condition). The metric of interest was the probability that a hospital would have as many deaths as it did (taking age, race, and sex into account). Differences among hospitals in inpatient death rates were large and significant (p less than .05) for 22 of 48 specific conditions studied and for all conditions together; among these 22 "high-variation" conditions, medical conditions accounted for far more deaths than did surgical conditions. We compared pairs of conditions in terms of hospital rankings by probability of observed numbers of inpatient deaths; we found relatively low correlations (Spearman correlation coefficients of 0.3 or lower) for most comparisons except between a few surgical conditions. When we compared different pairs of the four death measures on their rankings of hospitals by probabilities of the observed numbers of deaths, the correlations were moderate to high (Spearman correlation coefficients of 0.54 to 0.99). Hospitals with low probabilities of the number of observed deaths were not distributed randomly geographically; a small number of states had significantly more than their share of these hospitals (p less than .01). Information from hospital discharge abstract data is insufficient to determine the extent to which differences in severity of illness or quality of care account for this marked variability, so data on hospital death rates cannot now be used to draw inferences about quality of care. The magnitude of variability in death rates and the geographic clustering of facilities with low probabilities, however, both argue for further study of hospital death rates. These data may prove

    Background Mobile apps are being viewed as a new solution for post-operative monitoring of surgical patients. Mobile phone monitoring of patients in the post-operative period can allow expedited discharge and may allow early detection of complications. Objective The objective of the current study was to assess the feasibility of using a mobile app for the monitoring of post-operative quality of recovery at home following surgery in an ambulatory setting. Methods We enrolled 65 consecutive patients (n=33, breast reconstruction surgery; n=32, orthopedic surgery) and asked them to use a mobile phone daily to complete a validated quality of recovery scale (QoR-9) and take photographs of the surgical site for the first 30 days post-op. Surgeons were asked to review patient-entered data on each patient in their roster daily. A semistructured questionnaire was administered to patients and surgeons to assess satisfaction and feasibility of the mobile device. Results All 65 patients completed the study. The mean number of logins was 23.9 (range 7-30) for the breast patients and 19.3 (range 5-30) for the orthopedic patients. The mean number of logins was higher in the first 14 days compared to the 15-30 days post-op for both breast patients (13.4 vs 10.5; P<.001) and for the orthopedic patients (13.4 vs 6.0; P<.001). The mean score for overall satisfaction with using the mobile device was 3.9 for breast patients and 3.7 for orthopedic patients (scored from 1 (poor) to 4 (excellent)). Surgeons reported on the easy-to-navigate design, the portability to monitor patients outside of hospital, and the ability of the technology to improve time efficiency. Conclusions The use of mobile apps for monitoring the quality of recovery in post-operative patients at home was feasible and acceptable to patients and surgeons in the current study. Future large scale studies in varying patient populations are required. PMID:25679749

  9. [Infant mortality in Peru].

    Bolivia, Haiti, and Peru have infant mortality levels as high as those of the developed countries a century ago. The decline of general and especially infant mortality experienced in Latin America beginning in the 1940s was uneven throughout the continent. Cuba's infant mortality rate declined by 86% between 1940-80, but Peru's declined by only 48% despite its higher initial level. In 1984, 34% of all deaths in Peru were to children under 1 year and about 21% were to children 1-5 years old. Socioeconomic factors are the major explanation of Peru's poor infant mortality levels. Regional and social disparities in access to housing, food, urban infrastructure, and other vital goods and services are reflected in infant mortality statistics. Infant mortality has declined in both rural and urban areas, but the magnitude of the decline was much greater in urban areas. Between 1960-75, the infant mortality rate declined from 133 to 80/1000 live births in urban areas, but only from 180 to 150/1000 in rural areas. Investment in the infrastructure and services of the cities during the 1950s and 60s was not matched by any significant investment in rural infrastructure. Rural-urban mortality differentials are not as profound in countries which distribute public investment more evenly between rural and urban areas. Cuba's rural infant mortality rate is only 16% greater than its urban rate, while Peru's rural rate is 47% higher. The rural-urban differential in Peru hides a steep gap between the metropolitan zone of Lima-Callao, which has an infant mortality rate of 55/1000, and that of all cities, which have a rate 45% higher. Metropolitan Lima has the highest levels of living in Peru, including the highest incomes and best housing and service infrastructure. A majority of Peru's economic and industrial development has been concentrated in Lima. Peru's infant mortality differentials are also striking at the departmental level.

    Objective We hypothesized that deficiency in 25-hydroxy vitamin D at critical care initiation would be associated with all cause mortality. Design Two-center observational study. Setting Two teaching hospitals in Boston, Massachusetts Patients 1,325 patients, age ≥ 18 years, in whom 25-hydroxy vitamin D was measured 7 days prior to or after critical care initiation between 1998 and 2009. Measurements 25-hydroxy vitamin D was categorized as deficiency in 25-hydroxy vitamin D (≤15 ng/mL), insufficiency (16–29 ng/mL) and sufficiency (≥30 ng/mL). Logistic regression examined death by days 30, 90 and 365 post-critical care initiation and in hospital mortality. Adjusted odds ratios were estimated by multivariable logistic regression models. Interventions None Key Results 25-hydroxy vitamin D deficiency is predictive for short term and long term mortality. 30 days following critical care initiation, patients with 25-hydroxy vitamin D deficiency have an OR for mortality of 1.85 (95% CI, 1.15–2.98;P=0.01) relative to patients with 25-hydroxy vitamin D sufficiency. 25-hydroxy vitamin D deficiency remains a significant predictor of mortality at 30 days following critical care initiation following multivariable adjustment for age, gender, race, Deyo-Charlson index, sepsis, season, and surgical versus medical patient type (adjusted OR 1.94; 95% CI, 1.18–3.20;P=0.01). Results were similarly significant at 90 and 365 days following critical care initiation and for in hospital mortality. The association between vitamin D and mortality was not modified by sepsis, race, or Neighborhood poverty rate, a proxy for socioeconomic status. Conclusion Deficiency of 25-hydroxy vitamin D at the time of critical care initiation is a significant predictor of all cause patient mortality in a critically ill patient population. PMID:21926604

    Periampullary neoplasms are rapidly progressive tumors with a poor prognosis and high morbidity and mortality rates, which have a negative influence on patient outcomes. Some probiotics and prebiotics have the ability to protect the intestinal barrier and prevent bacterial translocation, infection, and postoperative complications. We evaluated the use of synbiotics in a prospective, double-blind study of patients undergoing surgery for periampullary neoplasms (PNs) and assessed the effect of these agents on nutritional status, postoperative complications, antibiotic use, length of hospital stay, and mortality. Patients were randomized to receive probiotics and prebiotics-synbiotics--group S [Lactobacillus acidophilus 10, 1 × 10(9)CFU, Lactobacillus rhamnosus HS 111, 1 × 10(9) CFU, Lactobacillus casei 10, 1 × 10(9) CFU, Bifidobacterium bifidum, 1 × 10(9)CFU, and fructooligosaccharides (FOS) 100 mg]--or placebo-controls--group C, twice daily, for a total of 14 days. Risk, clinical status, and postoperative complication rates were assessed. Twenty-three patients were allocated to each group. The incidence of postoperative infection was significantly lower in group S (6 of 23 patients, 26.1%) than in group C (16 of 23 patients, 69.6%) (P = 0.00). Duration of antibiotic therapy was also shorter in group S (mean = 9 days vs. 15 days in group C; P = 0.01). Noninfectious complications were less common in group S (6 of 23 vs. 14 of 23 patients in group C; P = 0.03). Mean length of hospital stay was 12 ± 5 days in group S vs. 23 ± 14 days in group C (P = 0.00). No deaths occurred in group S, whereas 6 deaths occurred in group C (P = 0.02). Perioperative administration of synbiotics reduces postoperative mortality and complication rates in patients undergoing surgery for PNs. PMID:25803626

    Background Surgical management is the basic treatment for hydatid disease. Overall, the recurrence rate appears to be high (4.6%–22.0%). The purpose of this study was to report our results in the management of recurrent hydatid disease, evaluating the methods for identifying recurrence, prognostic factors and therapeutic options. Methods We retrospectively reviewed the medical records of patients who underwent surgery for cystic hydatidosis between 1970 and 2003. Results Of the 584 patients who underwent surgery during our study period, follow-up was complete for 484 (82.8%). Cysts recurred in 51 patients (8.7%). Abdominal ultrasonography and computed tomography appeared to be efficient for diagnosing recurrence. The 2 most important determinants for recurrence were minute spillage of the hydatid cyst and inadequate treatment owing to missing cysts or incomplete pericystectomy. All but 2 recurrences required surgery. There were 14 postoperative complications for a rate of 27.0%. Thirteen re-recurrences were observed in the follow-up of these patients and also required surgery. Conclusion Avoidance of minute spillage of cyst contents and cautious removal of the parasite with as much of the pericyst as possible are fundamental objectives of primary hydatid surgery. Conservative surgery (removal of the cyst contents plus partial pericystectomy with drainage when necessary) plus chemotherapy and local sterilization is suggested for both primary and secondary operations and appears to achieve satisfactory long-term results. Radical surgery (resection, cystopericystectomy) is preferred only in select patients. PMID:21939605

    Exposure to real microgravity (muG) results in an impaired skeletal muscle structure and function. We here hypothesized that the cAMP/PKA cell signaling pathway, which triggers a multitude of intracellular effects in response to a variety of extracellular stimuli and which further promote muscle growth, play an important role during Spaceflight- induced disuse atrophy. Particularly, we hypothesized that different effectors of the cAMP-PKA signaling machinery, which are highly compartmentalized into subcellular functional microdomains in order to guarantee signal specificity, are altered after long term exposure to real µG. Taking advantage of the Bion-M1 Spaceflight program which provided us an excellent opportunity to explore mice skeletal muscle exposed for 30 days to real µG, by investigating at the cAMP-dependent protein kinase A (PKA) subcellular localization we compared muscle soleus (SOL) and extensor digitorum longus (EDL) of C57/black mice of a Bion-flight (n=5) group with a Bion-ground control (n=5) group and a ground control (n=5) group which was housed in a standard cage considered as vivarium control. Preliminary results of our experiments showed that different cAMP-PKA micro pools were normally detectable using high-resolution images of immunofluorescence experiments in different subcellular compartments of both SOL and EDL of Bion-ground and ground control groups which were not any longer detectable in Bion-flight group. In summary, our data indicate that an efficient organization in microdomains of the cAMP/PKA pathway may exist in skeletal muscle on ground and that such compartmentalization may be altered in response to prolonged exposure to real muG.

    In a prospective cohort study, the daily bodyweight (BW) and milk production of 92 cows were recorded using automatic milking systems. The objectives were to characterize calcium serum concentration variability on days 1-3 post-partum and to evaluate the association between subclinical hypocalcemia (SHPC) and change in BW over the first 30 days in milk (DIM) in Holstein dairy cows, while controlling for concurrent disease and negative energy balance (NEB). SHPC was defined as total serum calcium concentration between 6 and 8 mg/dL, NEB was defined as non-esterified fatty acids (NEFA) > 0.7 mEq/L or β-hydroxybutyrate (BHB) ≥ 1.2 mmol/L. The peak incidence of SHPC was at 1 DIM for all groups (11%, 42% and 60% for parities 1, 2, and ≥3, respectively). All parity groups lost weight (21, 33, and 34 kg) during the first 30 DIM. Parity 1 animals with disease compared with those without disease lost the most weight (2.6 kg/day BW loss vs. <1.9 kg/day, respectively). Normocalcemic parity 2 animals with either NEB or disease lost the most weight (>5 kg/day) compared with those in the SHPC group (≤4.5 kg/day). In parity ≥ 3 animals, SHPC was an important factor for BW loss; SHPC animals lost the most weight (>3.7 kg/day) vs. normocalcemic cows (≤3.3 kg/day) regardless of NEB or disease status. Even though all animals lost weight during early lactation the effect of disease, NEB, and SHPC on BW loss was different in each parity group. PMID:25819756

    STUDY OBJECTIVE--The study aimed to analyse avoidable mortality in Lithuania as an index of the quality of health care and to assess trends in avoidable mortality from 1970-90. SETTING AND PARTICIPANTS--All deaths of Lithuanian residents aged between 0 and 64 years between 1970 and 1990 were analysed. MEASUREMENTS AND MAIN RESULTS--Twenty seven per cent of all deaths in this age group were avoidable. Avoidable deaths were grouped into preventable and treatable ones. Treatable causes of death accounted for 54%, and preventable, 46% of avoidable mortality. Time trends showed that general mortality and mortality from avoidable causes of death in this age group were almost stable between 1970 and 1990. Mortality from treatable causes of death fell, while deaths from preventable causes increased. The results in the preventable group were greatly affected by deaths from malignant neoplasms of trachea, bronchus, and lungs. Differences were noted between the sexes in total mortality as well as in avoidable mortality. CONCLUSIONS--Avoidable causes of death are relatively common and, consequently, they are of practical importance for public health and studies of the health care quality in Lithuania. Reorganisation of health care is to be carried out and considerable emphasis will be placed on health education, promotion, and prevention, as primary prevention measures have not been effective thus far.

    The aim of this study was to determine nurses' knowledge and attitudes regarding postoperative pain and identify postoperative patients' pain intensity experiences. The assessment and management of acute postoperative pain is important in the care of postoperative surgical patients. Inadequate relief of postoperative pain can contribute to postoperative complications such as atelectasis, deep vein thrombosis, and delayed wound healing. A pilot study with an exploratory design was conducted at a large teaching hospital in the eastern United States. The convenience samples included 31 nurses from the gastrointestinal and urologic surgical units and 14 first- and second-day adult postoperative open and laparoscopic gastrointestinal and urologic patients who received patient-controlled analgesia (PCA). The Knowledge and Attitudes Survey Regarding Pain was used to measure nurses' knowledge about pain management. The Short-Form McGill Pain Questionnaire (SF-MPQ) was used to measure patients' pain intensity. The nurses' mean score on the Knowledge and Attitudes Survey Regarding Pain was 69.3%. Patients experienced moderate pain, as indicated by the score on the SF-MPQ. There is a need to increase nurses' knowledge of pain management. PMID:24315258

    Thirty postoperative patients, after undergoing abdominal hysterectomy and standard general anesthesia, were randomly allocated to three groups and received, in the recovery ward, a continuous infusion of either pentazocine, piritramide, or ketamine. The patients rated their pain on a 15-cm visual analog scale. Patients in group 1 received pentazocine. Mean dosage was 0.12 mg/kg/hr on the day of operation, 0.1 mg/kg/hr on the first postoperative day, and only 0.07 mg/kg/hr on the second postoperative day. Pentazocine blood levels averaged 50 micrograms/L. Patients in group 2 received piritramide. Mean dosage was 0.038 mg/kg/hr on the day of operation, 0.024 mg/kg/hr on the first postoperative day, and 0.019 mg/kg/hr on the second postoperative day. Blood levels of piritramide were not determined because no satisfactory assay is available. Patients in group 3 received ketamine. Mean dosage was 0.32 mg/kg/hr on the day of operation, 0.28 mg/kg/hr on the first postoperative day, and 0.29 mg/kg/hr on the second postoperative day. Ketamine blood levels ranged between 120 and 180 micrograms/L. None of the three analgesics caused any important hemodynamic or respiratory side effects. Pentazocine and piritramide were more effective analgesics than ketamine was. Ketamine also had a higher incidence of side effects. PMID:6627285

    In the Pediatric Surgical Department of The St Radboud Hospital, Nijmegen, The Netherlands, between January 1970 and December 1980, 1476 laparotomies were performed on neonates, infants, and children. In 33 of these patient the abdominal surgery was complicated by a postoperative small bowel obstruction (SBO), for which a second laparotomy had to be performed. In 80% of patients this SBO developed within three months of the prior operation. The risk of developing an adhesive SBO was greater when there was more than one prior peritoneal procedure, and when, during this prior procedure, there was already a peritonitis. There was no obvious relation with the nature of the original operation. In more than 70% of patients a single adhesion caused the obstruction, while in many of these cases there were already circulatory disturbances, even by early reintervention. The mortality was 6%.

    There is increasing evidence to support the hypothesis that epidural anesthesia and analgesia (EAA) can improve surgical outcome by reducing postoperative morbidity and hastening recovery. Likely benefits include decreased incidence of cardiac complications in high-risk patients; lower incidence of pulmonary complications, specifically pneumonia, atelectasis, and hypoxemia in patients at risk for pulmonary complications; lower incidence of vascular graft occlusion after lower extremity revascularization; lower incidence of DVT and pulmonary embolus; suppression of the neuroendocrine stress response; and earlier return of gastrointestinal function. Nonetheless, large multicenter prospective randomized studies are required to more definitively assess the impact of EAA on morbidity and mortality, ICU time, length of hospitalization, and cost of healthcare.

    2013-01-01

    Background In line with the growing number of surgical procedures being performed worldwide, postoperative complications are also increasing proportionately. Prevention of these postoperative complications is a high medical priority. Preoperative education of patients, including provision of preparatory information about the correct behavior after surgery, could improve the postoperative outcome, but the evidence for this is inconclusive. The aim of the PEDUCAT trial is to evaluate the feasibility and the impact of preoperative patient education on postoperative morbidity, mortality and quality of life in patients scheduled for elective major visceral surgery. Methods/design PEDUCAT is designed as a cluster-randomized controlled pilot study. The experimental group will visit a standardized preoperative seminar to learn how best to behave after surgery in addition to being given a standard information brochure, whereas the control group will only receive the information brochure. Outcome measures such as postoperative morbidity, postoperative pain, postoperative anxiety and depression, patient satisfaction, quality of life, length of hospital stay and postoperative mortality will be evaluated. Statistical analysis will be based on the intention-to-treat population. Analysis of covariance will be applied for the intervention group comparison, adjusting for age, center and quality of life before surgery. This is a pilot study to show the feasibility of the concept. Nevertheless, the planned sample size of n = 204 is large enough to show an effect with power of 90% and a significance level of 5%.

    Postoperative pulmonary complication (PPC) remains the most common postoperative complication in patients undergoing noncardiac thoracic surgery. We conducted the clinical study to determine the diagnostic role of miRNA-21 in noncardiac thoracic surgery. 368 patients undergoing noncardiac thoracic surgery were recruited. Blood samples were collected before anesthesia and 2 hours after incision during surgery for RT-PCR measurement of miRNA-21. PPC occurrence, extrapulmonary complications, duration of ICU stay, and death within 1 year were evaluated. The overall rate of PPCs following surgery was 10.32%. A high relative miRNA-21 level was an independent risk factor for PPCs within 7 days (OR, 2.69; 95% CI, 1.25–5.66; and P < 0.001). High miRNA-21 was also associated with an increased risk of extrapulmonary complications (OR, 3.62; 95% CI, 2.26–5.81; and P < 0.001), prolonged ICU stay (OR, 6.54; 95% CI, 2.26–18.19; and P < 0.001), increased death within 30 days (OR, 6.17; 95% CI, 2.11–18.08; and P < 0.001), and death within 1 year (OR, 7.30; 95% CI, 2.76–19.28; and P < 0.001). In summary, plasma miRNA-21 may serve as a novel biomarker of PPCs for patients undergoing noncardiac thoracic surgery. PMID:27293316

    The National Surgical Quality Improvement Project (NSQIP) is widely recognized as "the best in the nation" surgical quality improvement resource in the United States. In particular, it rigorously defines postoperative morbidity outcomes, including surgical adverse events occurring within 30 days of surgery. Due to its manual yet expensive construction process, the NSQIP registry is of exceptionally high quality, but its high cost remains a significant bottleneck to NSQIP's wider dissemination. In this work, we propose an automated surgical adverse events detection tool, aimed at accelerating the process of extracting postoperative outcomes from medical charts. As a prototype system, we combined local EHR data with the NSQIP gold standard outcomes and developed machine learned models to retrospectively detect Surgical Site Infections (SSI), a particular family of adverse events that NSQIP extracts. The built models have high specificity (from 0.788 to 0.988) as well as very high negative predictive values (>0.98), reliably eliminating the vast majority of patients without SSI, thereby significantly reducing the NSQIP extractors' burden.

    We retrospectively reviewed 2989 consecutive patients with a mean age of 81 (21 to 105) and a female to male ratio of 5:2 who were admitted to our hip fracture unit between July 2009 and February 2013. We compared weekday and weekend admission and weekday and weekend surgery 30-day mortality rates for hip fractures treated both surgically and conservatively. After adjusting for confounders, weekend admission was independently and significantly associated with a rise in 30-day mortality (odds ratio (OR) 1.4, 95% confidence interval (CI) 1.02 to 1.9; p = 0.039) for patients undergoing hip fracture surgery. There was no increase in mortality associated with weekend surgery (OR 1.2, 95% CI 0.8 to 1.7; p = 0.39). All hip fracture patients, whether managed surgically or conservatively, were more likely to die as an inpatient when admitted at the weekend (OR 1.4, 95% CI 1.02 to 1.80; p = 0.032), despite our unit having a comparatively low overall inpatient mortality (8.7%). Hip fracture patients admitted over the weekend appear to have a greater risk of death despite having a consultant-led service. PMID:24589794

    Pneumonectomy for benign disease is rare but may generate more postoperative morbimortality than when performed for lung cancer. We questioned this assessment and retrospectively reviewed 1436 pneumonectomies and 54 completions of which 82 and 10 performed for benign disease (5.7% and 18.5%, respectively): left n=65 and right n=27. Indications were: post-tuberculosis destroyed lung (n=37), aspergilloma (n=18), bronchiectasis (n=19), infection (n=5), congenital malformations (n=5), inflammatory pseudotumor (n=3), trauma (n=2), post-radiation (n=2) and mucormycosis (n=1). Pneumonectomy consisted of 48 standard and 44 pleuro-pneumonectomies. Stump coverage by flaps was performed in 66.3% (61/92). Complications occurred in 21.7% (20/92) and postoperative deaths in 7.6% (7/92, of which 5 with fungal infections), which was not different than what was observed in lung cancer. There was no difference in fistula formation and mortality regarding the side, the type of resection and the protective role of stump coverage. Considering patients with fungal infections versus others, mortality was 26.3% (n=5/19) and 2.7% (n=2/74), respectively (P=0.0028). Pneumonectomy for benign disease achieves cure with acceptable mortality and morbidity. However, presence of fungal infection should raise the attention for possibility of increased postoperative risks. PMID:25131368

    Objective This study sought to determine the influence of postoperative complications on the clinical outcomes of patients who underwent thoracic and gastrointestinal cancer surgery. Methods A prospective cohort study was conducted regarding 179 consecutive patients who received thorax or digestive tract surgery due to cancer and were admitted to an oncological intensive care unit. The Postoperative Morbidity Survey was used to evaluate the incidence of postoperative complications. The influence of postoperative complications on both mortality and length of hospital stay were also assessed. Results Postoperative complications were found for 54 patients (30.2%); the most common complications were respiratory problems (14.5%), pain (12.9%), cardiovascular problems (11.7%), infectious disease (11.2%), and surgical wounds (10.1%). A multivariate logistic regression found that respiratory complications (OR = 18.68; 95%CI = 5.59 - 62.39; p < 0.0001), cardiovascular problems (OR = 5.06, 95%CI = 1.49 - 17.13; p = 0.009), gastrointestinal problems (OR = 26.09; 95%CI = 6.80 - 100.16; p < 0.0001), infectious diseases (OR = 20.55; 95%CI = 5.99 - 70.56; p < 0.0001) and renal complications (OR = 18.27; 95%CI = 3.88 - 83.35; p < 0.0001) were independently associated with hospital mortality. The occurrence of at least one complication increased the likelihood of remaining hospitalized (log-rank test, p = 0.002). Conclusions Postoperative complications are frequent disorders that are associated with poor clinical outcomes; thus, structural and procedural changes should be implemented to reduce postoperative morbidity and mortality.

    Postoperative delirium is associated with increased morbidity, mortality and cost. However, its neuropathogenesis remains largely unknown, partially owing to lack of animal model(s). We therefore set out to employ a battery of behavior tests, including natural and learned behavior, in mice to determine the effects of laparotomy under isoflurane anesthesia (Anesthesia/Surgery) on these behaviors. The mice were tested at 24 hours before and at 6, 9 and 24 hours after the Anesthesia/Surgery. Composite Z scores were calculated. Cyclosporine A, an inhibitor of mitochondria permeability transient pore, was used to determine potential mitochondria-associated mechanisms of these behavioral changes. Anesthesia/Surgery selectively impaired behaviors, including latency to eat food in buried food test, freezing time and time spent in the center in open field test, and entries and duration in the novel arm of Y maze test, with acute onset and various timecourse. The composite Z scores quantitatively demonstrated the Anesthesia/Surgery-induced behavior impairment in mice. Cyclosporine A selectively ameliorated the Anesthesia/Surgery-induced reduction in ATP levels, the increases in latency to eat food, and the decreases in entries in the novel arm. These findings suggest that we could use a battery of behavior tests to establish a mouse model to study postoperative delirium. PMID:27435513

  8. Postoperative Pulmonary Dysfunction and Mechanical Ventilation in Cardiac Surgery

    2015-01-01

    Postoperative pulmonary dysfunction (PPD) is a frequent and significant complication after cardiac surgery. It contributes to morbidity and mortality and increases hospitalization stay and its associated costs. Its pathogenesis is not clear but it seems to be related to the development of a systemic inflammatory response with a subsequent pulmonary inflammation. Many factors have been described to contribute to this inflammatory response, including surgical procedure with sternotomy incision, effects of general anesthesia, topical cooling, and extracorporeal circulation (ECC) and mechanical ventilation (VM). Protective ventilation strategies can reduce the incidence of atelectasis (which still remains one of the principal causes of PDD) and pulmonary infections in surgical patients. In this way, the open lung approach (OLA), a protective ventilation strategy, has demonstrated attenuating the inflammatory response and improving gas exchange parameters and postoperative pulmonary functions with a better residual functional capacity (FRC) when compared with a conventional ventilatory strategy. Additionally, maintaining low frequency ventilation during ECC was shown to decrease the incidence of PDD after cardiac surgery, preserving lung function. PMID:25705516

    Using data from the Joint Commission's ORYX initiative and the Medicare Provider Analysis and Review file from 2003 to 2006, this study employed a fixed-effects approach to examine the relationship between hospital market competition, evidence-based performance measures, and short-term mortality at seven days, 30 days, 90 days, and one year for patients with chronic heart failure. We found that, on average, higher adherence with most of the Joint Commission's heart failure performance measures was not associated with lower mortality; the level of market competition also was not associated with any differences in mortality. However, higher adherence with the discharge instructions and left ventricular function assessment indicators at the 80th and 90th percentiles of the mortality distribution was associated with incrementally lower mortality rates. These findings suggest that targeting evidence-based processes of care might have a stronger impact in improving patient outcomes. PMID:22931022

  11. [Mortality of myocardial infarction].

    Coronary disease is a major cause of death and disability. From 1975 to 2000, coronary mortality was reduced by half. Better treatments and reduction of risk factors are the main causes. This phenomenon is observed in most developed countries, but mortality from coronary heart disease continues to increase in developing countries. In-hospital mortality of ST elevation myocardial infarction (STEMI) is in the range of 7 to 10% in registries. In infarction without ST segment elevation (NSTEMI), in-hospital mortality is around 5%. More recent studies found a similar in-hospital mortality for STEMI and NSTEMI. Because of patient selection and monitoring, mortality in clinical trials is much lower. After adjustment for the extent of coronary disease, age, risk factors, history of myocardial infarction, the excess mortality observed in women is fading. Many clinical, biological and laboratory parameters are associated with mortality in myocardial infarction. They refer to the immediate risk of death (ventricular rhythm disturbances, shock…), the extent of infarction (number of leads with ST elevation on the ECG, release of biomarkers, ejection fraction…), the presence of heart failure, the failure of reperfusion and the patient's baseline risk (age, renal function…). Risk scores, and more specifically the GRACE risk score, synthesize these different markers to predict the risk of death in a given patient. However, their use for the treatment of myocardial only concerns NSTEMI. Only a limited number of mechanical or pharmacological interventions reduces mortality of heart attack. The main benefits are observed with reperfusion by thrombolysis or primary angioplasty in STEMI, aspirin, heparin, beta-blockers, angiotensin converting enzyme inhibitors. Some medications such as bivalirudin and fondaparinux reduce mortality by decreasing the incidence of hemorrhagic complications. The guidelines classify interventions according to their benefit and especially their ability

    Little is known about the long-term sequelae of community-acquired pneumonia (CAP). Therefore, we describe the long-term morbidity and mortality of patients after pneumonia requiring hospitalization. We specifically hypothesized that the Pneumonia Severity Index (PSI), designed to predict 30-day pneumonia-related mortality, would also be associated with longer-term all-cause mortality. Between 2000 and 2002, 3415 adults with CAP admitted to 6 hospitals in Edmonton, Alberta, Canada, were prospectively enrolled in a population-based cohort. At the time of hospital admission, demographic, clinical, and laboratory data were collected and the PSI was calculated for each patient. Postdischarge outcomes through to 2006 were ascertained using multiple linked administrative databases. Outcomes included all-cause mortality, hospital admissions, and re-hospitalization for pneumonia over a maximum of 5.4 years of follow-up. Follow-up data were available for 3284 (96%) patients; 66%were > or =65 years of age, 53% were male, and according to the PSI fully 63% were predicted to have greater than 18% 30-day pneumonia-related mortality (that is, PSI class IV-V). Median follow-up was 3.8 years. The 30-day, 1-year, and end of study mortality rates were 12%, 28%, and 53%, respectively. Overall, 82(19%) patients aged <45 years died compared with 1456 (67%) patients aged > or =65 years (hazard ratio [HR], 5.07; 95% confidence interval [CI], 4.06-6.34). Male patients were more likely to die than female patients during follow-up (971 [56%] vs. 767 [49%], respectively; HR, 1.20; 95% CI, 1.13-1.37). Initial PSI classification predicted not only 30-day mortality, but also long-term postdischarge mortality, with 92 (15%) of PSI class I-II patients dying compared with 616 (82%) PSI class V patients (HR, 11.80; 95% CI, 4.70-14.70). Of 2950 patients who survived the initial CAP hospitalization, 72% were hospitalized again (median, 2 admissions over follow-up) and 16% were re-hospitalized with

    Objective To evaluate the association of pretrauma center (PTC) red blood cell (RBC) transfusion with outcomes in severely injured patients. Background Hemorrhage remains a major driver of mortality. Little evidence exists supporting PTC interventions to mitigate this. Methods Blunt injured patients in shock arriving at a trauma center within 2 hours of injury were included from the Glue Grant database. Subjects were dichotomized by PTC RBC transfusion. Outcomes included 24-hour mortality, 30-day mortality, and trauma-induced coagulopathy [(TIC), admission international normalized ratio >1.5]. Cox regression and logistic regression determined the association of PTC RBC transfusion with outcomes. To address baseline differences, propensity score matching was used. Results Of 1415 subjects, 50 received PTC RBC transfusion. Demographics and injury severity score were similar. The PTC RBC group received 1.3 units of RBCs (median), and 52% were scene transports. PTC RBC transfusion was associated with a 95% reduction in odds of 24-hour mortality [odds ratio (OR) = 0.05; 95% confidence interval (CI), 0.01–0.48; P < 0.01], 64% reduction in the risk of 30-day mortality [hazard ratio = 0.36; 95% CI, 0.15–0.83; P = 0.02], and 88% reduction in odds of TIC (OR = 0.12; 95% CI, 0.02–0.79; P = 0.03). The matched cohort included 113 subjects (31% PTC RBC group). Baseline characteristics were similar. PTC RBC transfusion was associated with a 98% reduction in odds of 24-hour mortality (OR = 0.02; 95% CI, 0.01–0.69; P = 0.04), 88% reduction in the risk of 30-day mortality (hazard ratio = 0.12; 95% CI, 0.03–0.61; P = 0.01), and 99% reduction in odds of TIC (OR = 0.01; 95% CI, 0.01–0.95; P = 0.05). Conclusions PTC RBC administration was associated with a lower risk of 24-hour mortality, 30-day mortality, and TIC in severely injured patients with blunt trauma, warranting further prospective study.

    The purpose of this article is to describe factors contributing to potentially preventable mortality in academic medical centers and the organizational characteristics associated with success in reducing mortality. Sixteen U.S. academic medical centers that wished to improve risk-adjusted inpatient mortality rates requested a consultation that included interviews with physicians, nurses, and hospital leaders; review of medical records; and evaluation of systems and processes of care. The assessments took place on-site; they identified key factors contributing to preventable mortality, and each hospital received specific recommendations. Changes in observed mortality and in the ratio of observed to expected mortality were measured from 2002 to final follow-up in 2007. Evaluations determined each hospital's success factors and key barriers to improvement. The key factors contributing to preventable mortality were delays in responding to deteriorating patients, suboptimal critical care, hospital-acquired infections, postoperative complications, medical errors, and community issues such as the availability of hospice care. Of the 16 hospitals, 12 were able to reduce their mortality index. The five hospitals that had the greatest improvement in mortality were the only hospitals with a broad level of engagement among hospital and physician leaders, including the department chairs. In the hospitals whose performance did not improve, the department chairs were not engaged in the process. The academic medical centers that focused on mortality reduction and had engagement of physicians, especially department chairs, were able to achieve meaningful reductions in hospital mortality. The necessary ingredients for achieving meaningful improvement in clinical outcomes included good data, a sound method for change, and physician leadership. PMID:19940569

    Objective: To evaluate the mortality rate in patients with narcolepsy. Design: Data were derived from a large database representative of the US population, which contains anonymized patient-linked longitudinal claims for 173 million individuals. Setting: Symphony Health Solutions (SHS) Source Lx, an anonymized longitudinal patient dataset. Patients/Participants: All records of patients registered in the SHS database between 2008 and 2010. Interventions: None Measurements and Results: Identification of patients with narcolepsy was based on ≥ 1 medical claim with the diagnosis of narcolepsy (ICD-9 347.xx) from 2002 to 2012. Dates of death were acquired from the Social Security Administration via a third party; the third party information was encrypted in the same manner as the claims data such that anonymity is ensured prior to receipt by SHS. Annual all-cause mortality rates for 2008, 2009, and 2010 were calculated retrospectively for patients with narcolepsy and patients without narcolepsy in the database, and standardized mortality ratios (SMR) were calculated. Mortality rates were also compared with the general US population (Centers for Disease Control data). SMRs of the narcolepsy population were consistent over the 3-year period and showed an approximate 1.5-fold excess mortality relative to those without narcolepsy. The narcolepsy population had consistently higher mortality rates relative to those without narcolepsy across all age groups, stratified by age decile, from 25-34 years to 75+ years of age. The SMR for females with narcolepsy was lower than for males with narcolepsy. Conclusions: Narcolepsy was associated with approximately 1.5-fold excess mortality relative to those without narcolepsy. While the cause of this increased mortality is unknown, these findings warrant further investigation. Citation: Ohayon MM; Black J; Lai C; Eller M; Guinta D; Bhattacharyya A.

    Ultrasonography of the postoperative musculoskeletal system plays an important role in the Epub ahead of print accurate diagnosis of abnormal lesions in the bone and soft tissues. Ultrasonography is a fast and reliable method with no harmful irradiation for the evaluation of postoperative musculoskeletal complications. In particular, it is not affected by the excessive metal artifacts that appear on computed tomography or magnetic resonance imaging. Another benefit of ultrasonography is its capability to dynamically assess the pathologic movement in joints, muscles, or tendons. This article discusses the frequent applications of musculoskeletal ultrasonography in various postoperative situations including those involving the soft tissues around the metal hardware, arthroplasty, postoperative tendons, recurrent soft tissue tumors, bone unions, and amputation surgery.

    In this study of 99 tuberculous meningitis patients from Cali, Colombia, treatment with steroids (in conjunction with antituberculous drugs) was shown to be more effective in reducing mortality than treatment with antibacterial drugs alone. Results further suggest that low dosages of steroids (1 mg/kg of prednisone daily for r 30 days) are equally effective in treating the disease as high dosages (10 mg/kg of prednisone at the start of treatment, gradually reduced over a 30-day period). These results are band 4(-43 and -kk mg/100 ml) demonstrated cerebral release. Arterial blood hyperammonemia can be detoxified safely in the brain as long as the levels do not exceed approximately 300 mug/100 ml. Beyond that level lactic acidosis is observed, particularly in cerebral venous drainage. Arterial blood hyperammonemia was also related to the extent of alveolar hyperventilation. These findings are very similar to those seen in experimental hyperammonemia and support the concept that neurotoxicity in children with Reye's syndrome is at least partly due to impaired oxidative metabolism secondary to hyperammonemia.

  18. Mortality in Asia.

    1981-01-01

    Although the general trend in mortality between 1950 and 1975 in South and East Asia has been downward, there is considerable country-to-country variation in the rate of decline. In countries where combined economic, social, and political circumstances resulted in controlling the disease spectrum (e.g., China, Malaysia, Sri Lanka), mortality levels declined to those seen in low-mortality countries. In most of the large countries of the region however, mortality declined at a slower rate, even slowing down considerably in the 1970's while the death rates remained high (e.g., India, Bangladesh, Thailand, Philippines); this slowing down of mortality level is attributed essentially to the poverty-stricken masses of society which were not able to take advantage of social, technological, and health-promoting behavioral changes conducive to mortality decline. Infant mortality levels, although declining since 1950, followed the same dismal pattern of the general mortality level. The rate varies from less than 10/1000 live births (Japan) to more than 140/1000 (Bangladesh, Laos, Nepal). Generally, rural areas exhibited higher infant mortality than urban areas. The level of child mortality declines with increases in the mother's educational level in Bangladesh, India, Indonesia, Sri Lanka, and Thailand. The largest decline in child mortality occurs when at least 1 parent has secondary education. The premature retardation of mortality decline is caused by several factors: economic development, nutrition and food supply, provision and adequacy of health services, and demographic trends. The outlook for the year 2000 for most of Asia's countries will depend heavily on significant population increases. In most countries, particularly in South Asia, population is expected to increase by 75%, much of it in rural areas and among poorer socioeconomic groups. In view of this, Asia's health planners and policymakers will have to develop health policies which will strike a balance

    Objective: To evaluate the clinical and functional outcomes from patients undergoing surgery to treat hip fractures, with regard to the ASA score and time spent waiting for definitive surgical treatment. Method: Over a one-year period, 154 patients with hip fractures, aged 65 years and over, underwent operations. Data on the preoperative ASA score and the time spent waiting for the operation were obtained. Two years after the operation, Zuckerman‘s Functional Recovery Score (FRS) questionnaire was used to assess the patients' current functional capacity. Results: Mortality during the first postoperative year differed between patients with ASA 3 or 4 and those classified as ASA 1 or 2 (significant data; p < 0.05). Mortality up to the end of the second postoperative year was significantly higher (p < 0.05) in the ASA 3 or 4 group. The preoperative ASA score did not demonstrate any significant relationship with the patients' current functional capacity (p > 0.05). There was no significant difference between the group operated within 48 hours of admission and the group operated after 48 hours, in relation to mortality or current functional capacity (p > 0.05). The group aged 80 years and over showed significantly higher mortality (p < 0.05) than the group aged 65 to 79 years up to the end of the second postoperative year. Conclusion: The preoperative ASA score and an age of 80 years or over may be considered to be factors associated with higher mortality two years after hip fracture surgery. In isolation, time spent waiting for surgery was not significant. PMID:27026967

    Following the devastating flood years of 1998 during which 60% of Bangladesh was under water for a period of 3 months, the Climate Forecast Applications in Bangladesh (CFAB) project was formed with funding by USAID and NSF which eventually resulted in a joint project with the European Centre for Medium Range Weather Forecasting (ECMWF), the Asian Disaster Preparedness Centre (ADPC) and the Bangladesh Flood Forecasting and Warning Centre. The project was organized and developed through the Georgia Institute of Technology. The aim of CFAB was to develop innovative methods of extending the warning of flooding in Bangladesh noting that there was a unique problem: India provided no upstream discharge data to Bangladesh so that before CFAB the maximum lead time of a forecast was that given by measuring river discharge at the India-Bangladesh border: no lead-time at the border and 2 days in the southern parts of the country. Given that the Brahmaputra and Ganges catchment areas had to be regarded as essentially unguaged, it was clear that innovative techniques had to be developed. On of the basic criterion was that the system should provide probabilistic forecasts in order for the Bangladeshis to assess risk. A three-tier system was developed to allow strategic and tactical decisions to be made for agricultural purposes and disaster mitigation: seasonal (1-6 months: strategic), medium range (20-30 days: strategic/tactical) and short range (1-10 days: tactical). The system that has been developed brings together for the first time operational meteorological forecasts (ensemble forecasts from ECMWF), with satellite and discharge data and a suite of hydrological models. In addition, with ADPC and FFWC we have developed an in-country forecast dispersion system that allows a rapid dissemination. The system has proven to be rather successful, especially in the short range. The flooding events of 2004 were forecast with all forecasting tiers at the respective lead time. In

    Postoperative pain has been poorly managed for decades. Recent surveys from USA and Europe do not show any major improvement. Persistent postoperative pain is common after most surgical procedures, and after thoracotomy and mastectomy, about 50% of patients may experience it. Opioids remain the mainstay of postoperative pain treatment in spite of strong evidence of their drawbacks. Multimodal analgesic techniques are widely used but new evidence is disappointing. Regional anaesthetic techniques are the most effective methods to treat postoperative pain. Current evidence suggests that epidural analgesia can no longer be considered the 'gold standard'. Perineural techniques are good alternatives for major orthopaedic surgery but remain underused. Infiltrative techniques with or without catheters are useful for almost all types of surgery. Simple surgeon-delivered local anaesthetic techniques such as wound infiltration, preperitoneal/intraperitoneal administration, transversus abdominis plane block and local infiltration analgesia can play a significant role in improvement of postoperative care, and the last of these has changed orthopaedic practice in many institutions. Current postoperative pain management guidelines are generally 'one size fits all'. It is well known that pain characteristics such as type, location, intensity and duration vary considerably after different surgical procedures. Procedure-specific postoperative pain management recommendations are evidence based, and also take into consideration the role of anaesthetic and surgical techniques, clinical routines and risk-benefit aspects. The role of acute pain services to improve pain management and outcome is well accepted but implementation seems challenging. The need for upgrading the role of surgical ward nurses and collaboration with surgeons to implement enhanced recovery after surgery protocols with regular audits to improve postoperative outcome cannot be overstated.

    Purpose Redo cardiac operations represent one of the main challenges in heart surgery. The purpose of the study was to analyze the predictors of in-hospital mortality in patients undergoing reoperative cardiac surgery by a single surgical team. Methods A total of 1367 patients underwent cardiac surgical procedures and prospectively entered into a computerized database. Patients were divided into 2 groups based on the reoperative cardiac surgery (n = 109) and control group (n = 1258). Uni- and multivariate logistic regression analysis were performed to evaluate the possible predictors of hospital mortality. Results Mean age was 56 ± 13, and 46% were female in redo group. In-hospital mortality was 4.6 vs. 2.2%, p = 0.11. EuroSCORE (6 vs. 3; p < 0.01), cardiopulmonary bypass time (90 vs. 71 min; p < 0.01), postoperative bleeding (450 vs. 350 ml; p < 0.01), postoperative atrial fibrillation (AF) (29 vs. 16%; p < 0.01), and inotropic support (58 vs. 31%; p = 0.001) were significantly different. These variables were entered into uni- and multivariate regression analysis. Postoperative AF (OR1.76, p = 0.007) and EuroSCORE (OR 1.42, p < 0.01) were significant risk factors predicting hospital mortality. Conclusions Reoperative cardiac surgery can be performed under similar risks as primary operations. Postoperative AF and EuroSCORE are predictors of in-hospital mortality for redo cases.

We identified 6,024 patients on 1 DMARD or BA in the perioperative period between 1999 and 2009. Time gap between medication stop date and the next start date predicted drug stoppage (X). Time gap between surgery date and stop date predicted whether stoppage was before surgery (Y). Chart review from Houston VA was used for validation. ROC analyses were performed on chart review data to obtain X and Y cutoffs. The primary endpoints were wound infections and other infections within 30 days. ROC analyses found X ≥ 33 (AUC = 0.954) and Y ≥ -11 (AUC = 0.846). Risk of postoperative infections was not different when stopping and continuing DMARDs/BA preoperatively. Stopping BA after surgery was associated with higher odds of postoperative wound (OR 14.15, 95 % CI 1.76-113.76) and general infection (OR 9.2, 95 % CI 1.99-42.60) compared to not stopping. Stopping DMARDs after surgery was associated with increased risk of postoperative general infection (OR 1.84, 95 % CI 1.07-3.16) compared with not stopping. There was positive association between stopping DMARDs after surgery and postoperative wound infection but failed to achieve statistical significance (OR 1.67, 95 % CI 0.96-2.91). There was no significant difference in postoperative infection risk when stopping or continuing DMARD/BA. Our new validated method can be utilized in the VA and other databases to predict drug stoppage. PMID:25187198

  5. Postoperative assessment of vascular access.

    Vascular access problems lead to increased patient morbidity and mortality. Autologous arteriovenous fistulas (AVFs) are preferred over grafts. An increase in utilization of AVFs results in an increased incidence of early AVF failure and nonmaturation. A thorough evaluation of a new AVF after 4-6 weeks after creation should be considered mandatory. Experienced persons can examine AVF and predict its utility as a dialysis access. Detailed physical examination of the access performed by educated and trained staff can provide, in most cases, adequate information about the main causes for AVF dysfunction in case of nonmaturation or in case of late access complications. Physical examination has been shown to be very accurate in assessing fistula and is not difficult to learn. Doppler ultrasound (DU) is an additional diagnostic method to predict the ultimate maturation of newly created AVFs and is also very useful in further defining problems that have been detected by physical examination. DU also provides additional information that is of the utmost importance for the surgical or interventional treatment.In this review, basic principles of physical examination and of DU examination of early and late AVF/graft complications are shown.

    Weekend admission is associated with higher in-hospital mortality than weekday admission. Whether providing enhanced weekend staffing for acute medical inpatient services reduces mortality or length of stay is unknown. Methods This paper describes a retrospective analysis of in-hospital mortality and length of stay before and after introduction of an enhanced, consultant-led weekend service in acute medicine in November 2012. In-hospital mortality was compared for matching admission calendar months before and after introduction of the new service, adjusted for case volume. Length of stay and 30-day postdischarge mortality were also compared; illness severity of patients admitted was assessed by cross-sectional acuity audits. Results Admission numbers increased from 6,304 (November 2011-July 2012) to 7,382 (November 2012-July 2013), with no change in acuity score in elderly medical patients but a small fall in younger patients. At the same time, however, a 57% increase in early-warning score triggered calls was seen in 2013 (410 calls vs 262 calls in 2012; p<0.01). Seven-day consultant working was associated with a reduction in in-hospital mortality from 11.4% to 8.8% (p<0.001). Mortality within 30 days of discharge fell from 2.4% to 2.0% (p=0.12). Length of stay fell by 1.9 days (95% CI 1.1-2.7; p=0.004) for elderly medicine wards and by 1.7 days (95% CI 0.8-2.6; p=0.008) for medical wards. Weekend discharges increased from general medical wards (from 13.6% to 18.8%, p<0.001) but did not increase from elderly medicine wards. Conclusions Introduction of an enhanced, consultant-led model of working at weekends was associated with reduced in-hospital and 30-day post discharge mortality rates as well as reduced length of stay. These results require confirmation in rigorously designed prospective studies. PMID:27070886

    The research aim was 1) to determine the incidence of maternal mortality in a rural health center area in Sirur, Maharashtra state, India; 2) to determine the relative risk; and 3) to make suggestions about reducing maternal mortality. The data on deliveries was obtained between 1981 and 1984. Medical care at the Rural Training Center was supervised by the Department of Preventive and Social Medicine, the B.J. Medical College in Pune. Deliveries numbered 5994 singleton births over the four years; 5919 births were live births. 15 mothers died: 14 after delivery and 1 predelivery. The maternal mortality rate was 2.5/1000 live births. The maternal causes of death included 9 direct obstetric causes, 3 from postpartum hemorrhage of anemic women, and 3 from puerperal sepsis of anemic women with prolonged labor. 2 deaths were due to eclampsia, and 1 death was unexplained. There were 5 (33.3%) maternal deaths due to indirect causes (3 from hepatitis and 2 from thrombosis). One woman died of undetermined causes. Maternal jaundice during pregnancy was associated with the highest relative risk of maternal death: 106.4. Other relative risk factors were edema, anemia, and prolonged labor. Attributable risk was highest for anemia, followed by jaundice, edema, and maternal age of over 30 years. Maternal mortality at 30 years and older was 3.9/1000 live births. Teenage maternal mortality was 3.3/1000. Maternal mortality among women 20-29 years old was lowest at 2.1/1000. Maternal mortality for women with a parity of 5 or higher was 3.6/1000. Prima gravida women had a maternal mortality rate of 2.9/1000. Parities between 1 and 4 had a maternal mortality rate of 2.3/1000. The lowest maternal mortality was at parity of 3. Only 1 woman who died had received more than 3 prenatal visits. 11 out of 13 women medically examined prenatally were identified with the following risk factors: jaundice, edema, anemia, young or old maternal age, parity, or poor obstetric history.

    Background: The aim of this prospective audit was to investigate clinical practice related to muscle relaxant reversal and the impact made by the recent introduction of sugammadex on patient outcome at a tertiary teaching hospital. Methods: Data from all patients intubated at our institution during two epochs of seven consecutive days each was collected prospectively. Directly prior to extubation, the train-of-four (TOF) ratio was assessed quantitatively by an independent observer. Postoperative outcome parameters were complications in the recovery room and radiological diagnosed atelectasis or pneumonia within 30 days. Results: Data from 146 patients were analysed. Three reversal strategies were used: no reversal, neostigmine or sugammadex. The TOF ratio was less than 0.7 in 17 patients (nine no reversal, eight neostigmine) and less than 0.9 in 47 patients (24 no reversal, 19 neostigmine, four sugammadex). Those reversed with sugammadex showed fewer episodes of postoperative oxygen desaturation (15% vs. 33%; P<0.05). TOF ratios of less than 0.7 (P<0.05) and also <0.9 (P<0.01) were more likely associated with X-ray results consistent with postoperative atelectasis or pneumonia. Conclusions: Our results suggest a significant impact of residual paralysis on patient outcome. The use of sugammadex resulted in the lowest incidence of residual paralysis. PMID:23716766

  9. Postoperative management of hip fractures: interventions associated with improved outcomes.

    The annual number of hip fractures worldwide is expected to exceed 6 million by 2050. Currently, nearly 50% of hip fracture patients will develop at least one short-term complication including infection, delirium, venous thromboembolism (VTE), pressure ulcers or cardiovascular events. More than half will experience an adverse long-term outcomes including worsened ambulation or functional status, additional fractures and excess mortality. This paper summarizes current evidence for postoperative interventions attempting to improve these outcomes, including pain management, anemia management, delirium prevention strategies, VTE prophylaxis, rehabilitation type, nutritional supplements, anabolic steroids and secondary fracture prevention. Models of care that have been tested in this population including interdisciplinary orthogeriatric services, clinical pathways and hospitalist care are summarized. In general, good quality evidence supports routine use of VTE prophylaxis, and moderate quality evidence supports multifactorial delirium prevention protocols, and a conservative transfusion strategy. Aggressive pain control with higher doses of opiates and/or regional blocks are associated with lower delirium rates. Low-moderate quality evidence supports the use of clinical pathways, and dedicated orthogeriatric consultative services or wards. After hospital discharge, good quality evidence supports the use of bisphosphonates for secondary fracture prevention and mortality reduction. Rehabilitation services are important, but evidence to guide quantity, type or venue is lacking. Additional research is needed to clarify the role of nutritional supplements, anabolic steroids, home care and psychosocial interventions. PMID:24340216

    Background: Chronic rhinosinusitis has a major impact on the quality of life of patients with cystic fibrosis (CF) and may contribute to progression of chronic lung disease. Despite multiple sinus surgeries, maxillary sinus involvement is a recurrent problem. The modified endoscopic medial maxillectomy (MEMM) permits debridement in the clinic, improves mucus clearance with nasal irrigations, and increases access for topical delivery of therapeutics. However, clinical outcomes of aggressive sinus surgery with regimented postoperative medical treatment have not been systematically evaluated. Methods: CF patients completed the 22-Item Sinonasal Outcome Test questionnaires before sinus surgery (and bilateral MEMM) and at sequential postoperative visits. Objective measures included Lund-Kennedy endoscopic score and pulmonary function tests (forced expiratory volume at 1 second percent [FEV1%] predicted). Culture-directed antibiotic therapy, prednisone, and topical irrigations were initiated postoperatively. Results: Twenty-two patients (mean age, 26.5 years; 4.9 prior sinus operations) underwent MEMM and sinus surgery. Symptom scores were significantly reduced at 60 days (primary outcome, 64.7 ± 18.4 presurgery versus 27.5 ± 15.3 postsurgery; p < 0.0001) and up to a year postoperatively (27.6 ± 12.6; p < 0.0001). Endoscopic scores were also reduced after surgery (10.4 ± 1.1 presurgery versus 5.7 ± 2.4 [30 days], 5.7 ± 1.4 [60 days], 5.8 ± 1.3 [120 days], and 6.0 ± 1.1 [1 year]; p < 0.0001)]. There were no differences in FEV1% predicted up to 1 year postoperatively, but hospital admissions secondary to pulmonary exacerbations significantly decreased (2.0 ± 1.4 versus 3.2 ± 2.4, respectively; p < 0.05). Conclusion: Prospective evaluation indicates sinus surgery with MEMM is associated with marked improvement in sinus disease outcomes. Additional studies are necessary to confirm whether this treatment paradigm is associated with improved CF pulmonary disease

    A total of 197 consecutive patients undergoing pneumonectomy at the M.D. Anderson Cancer Center from 1982 to 1987 were reviewed. Sixty-five variables were analyzed for the predictive value for perioperative risk. The operative mortality rate was 7% (14/197). Patients having a right pneumonectomy (n = 95) had a higher operative mortality rate (12%) than patients having a left pneumonectomy (1%, p less than 0.05). The extent of resection correlated with the operative mortality rate (chest wall resection or extrapleural pneumonectomy, n = 39, 15%; versus simple or intrapericardial pneumonectomy, n = 158, 5%; p less than 0.05). Patients whose predicted postoperative pulmonary function, by spirometry and xenon 133 regional pulmonary function studies, was a forced expiratory volume in 1 second greater than 1.65 L, forced expiratory volume in 1 second greater than 58% of the preoperative value, forced vital capacity greater than 2.5 L, or forced vital capacity greater than 60% of the preoperative value had a lower operative mortality rate (p less than 0.05). Atrial arrhythmia was the most common postoperative complication (23%). Xenon 133 regional pulmonary function studies are useful in predicting the risks of pneumonectomy.

    Postoperative pulmonary complications are associated with increased morbidity, length of hospital stay, and mortality after major surgery. Intraoperative lung-protective mechanical ventilation has the potential to reduce the incidence of postoperative pulmonary complications. This review discusses the relevant literature on definition and methods to predict the occurrence of postoperative pulmonary complication, the pathophysiology of ventilator-induced lung injury with emphasis on the noninjured lung, and protective ventilation strategies, including the respective roles of tidal volumes, positive end-expiratory pressure, and recruitment maneuvers. The authors propose an algorithm for protective intraoperative mechanical ventilation based on evidence from recent randomized controlled trials. PMID:26120769

    Background Bloodstream infections (BSI) remain a frequent complication during the pre-engraftment period after hematopoietic stem cell transplantation (HSCT), resulting in high mortality rates. This study evaluated risk factors for mortality in hematopoietic stem cell transplant recipients with BSI in the pre-engraftment period. Methods This prospective case control study was performed at the Center of Hematology and Bone Marrow Transplantation in Minsk, Republic of Belarus. Data relating to patient age and gender, date and type of transplantation, conditioning chemotherapy regimen, microorganisms isolated from blood, and antibacterial therapy were prospectively collected from all hematopoietic stem cell recipients with microbiologically proven cases of BSI in the pre-engraftment period. The primary outcome was all-cause 30-day mortality after onset of febrile neutropenia. Results A total of 135 adult patients with microbiologically proven BSI after HSCT were studied, with 65.2% of cases caused by gram-negative microorganisms and 21.5% by non-fermenting bacteria. Inadequate empiric antibacterial therapy and isolation of carbapenem-resistant non-fermenting gram-negative bacteria (Acinetobacter baumannii and Pseudomonas aeruginosa) were independently associated with increased all-cause 30-day mortality in these patients. Conclusion The risk factors for mortality in adult patients with BSI in the pre-engraftment period after HSCT were inadequacy of empirical antibacterial therapy and isolation of carbapenem-resistant A. baumannii or P. aeruginosa.

    Hip femur is extremely common in the elderly and is one of the most common reasons for admission in trauma care. The main reported causes of death after hip fracture were cardiovascular (29%), neurological (20%) and pulmonary. Large epidemiological studies have shown a relatively small decrease in mortality for 20 years despite an active approach to medical and surgical management. Yet 57% of deaths occurring within 30 days post-surgery are preventable because they are not related to a pre-existing disease. Preoperative management to optimize these patients could help to reduce morbidity and mortality and is thus a crucial issue. The anesthesia consultation is used to evaluate the perioperative risk, treat pain, manage treatment and stabilize the patient. An operative delay of more than 48hours after admission increases mortality. This period should not be prolonged by unnecessary investigations that will not change the perioperative management. The preoperative period is a key moment because it allows to choose the anesthetic technique. Even if this choice is controversial, continuous spinal anesthesia (titrated) do not modify the cardiovascular and neurological physiological balance of these precarious patients. PMID:21945704

    Bone density insufficiency is the main cause for significant musculoskeletal trauma in the elderly population following low-energy falls. Hip fractures, in particular, represent an important public health concern taking into account the complicated needs of the patients due to their medical comorbidities as well as their rehabilitation and social demands. The annual cost for the care of these patients is estimated at around 2 billion pounds (£) in the UK and is ever growing. An increased early and late mortality rate is also recognised in these injuries together with significant adversities for the patients. Lately, in order to improve the outcomes of this special cohort of patients, fast-track care pathways and government initiatives have been implemented. It appears that these measures have contributed in a steady year-by-year reduction of the 30-day mortality rates. Whether we have currently reached a plateau or whether an ongoing reduction in mortality rates will continue to be observed is yet to be seen. PMID:26943870

    Previous studies have shown that nursing documentation is often deficient in its recording of pain assessment and treatment. In Sweden, documentation of the care process, including assessment, is a legal obligation. The aim of this study was to describe nursing documentation of postoperative pain management and nurses' perceptions of the records in relation to current regulations and guidelines. The sample included nursing records of postoperative care on the second postoperative day from 172 patients and 63 Registered Nurses from surgical wards in a central county hospital in Sweden. The records were reviewed for content and comprehensiveness based on regulations and guidelines for postoperative pain management. Three different auditing instruments were used. The nurses were asked if the documentation concurred with current regulations and guidelines. The result showed that pain assessment was based mainly on patients' self-report, but less than 10% of the records contained notes on systematic assessment with a pain assessment instrument. Pain location was documented in 50% of the records and pain character in 12%. About 73% of the nurses reported that the documentation concurred with current regulations and guidelines. The findings indicate that significant flaws existed in nurses' recording of postoperative pain management, of which the nurses were not aware. PMID:12427178

    Objective To improve understanding of perioperative deaths at an academic medical center. Summary Background Data Because published data have typically focused on specific patient populations, diagnoses, or procedures, there are few data regarding surgical deaths and complications in institutional or regional studies. Specifically, surgical adverse events and errors are generally not studied comprehensively. This limits the overall understanding of complications and deaths. Methods Data from all operations performed in the main operating suite of the University of Virginia Health Sciences Center from January 1 to June 30, 1999, were compared with state death records to gain a dataset of patients dying within 30 days of surgery. All clinical records from patients who died were screened for adverse events and subsequently reviewed by three surgeons who identified adverse events and errors and performed comparisons with survivors. Results One hundred nineteen deaths followed 7,379 operations performed on 6,296 patients, yielding a patient death rate of 1.9%. Patients dying within 30 days of surgery were older and had higher American Society of Anesthesiologists scores. Of 119 deaths, 86 (72.3%) were attributable to the patient’s primary disease. Twenty-three patient deaths (19.3% of all deaths, 0.37% of all patients) could not be attributed to the patient’s primary disease and thus were suspicious for an adverse event (AE) as the cause of the death. Of the 23 deaths suspicious for AE, 15 (12.6% of all deaths, and 65.2% of AE deaths) followed an error in care and thus were classified as potentially preventable, affecting 0.24% of the study population. Conclusions Overall, the 30-day postoperative death rate was low in the total surgical population at an academic medical center. Errors and AEs were associated with 12.6% and 19.3% of deaths, respectively. Retrospective review inadequately characterized the nature of AEs and failed to determine causality. Prospective

    The author calculated the relationship between instantaneous natural mortality, M (d[sup [minus]1]), and dry body weight, W ([mu]g), for herring larvae and adults using data from the scientific literature. Geometric mean mortality of adult Pacific herring Clupea pallasi (0.52[center dot]year[sup [minus]1]), was about three times greater than that of adult Atlantic herring Clupea harengus (0.18 year[sup [minus]1]), which may reflect greater reproductive effort per unit size by Pacific herring than by Atlantic herring. Geometric mean mortality of Pacific herring larvae (0.083[center dot]d[sup [minus]1]) was 30% greater than that of Atlantic herring larvae (0.064[center dot]d[sup [minus]1]), but the difference was not significant. The functional regression for Atlantic herring was log[sub e](M) = -0.4924 - 0.4064[center dot]log[sub e](W), and the regression for Pacific herring was log[sub e](M) = 0.1553 0.3935[center dot]log[sub e](W). The regressions provide preliminary estimates of average M of herring eggs and juveniles, life history stages for which there are few direct estimates of mortality. They also indicate that the weight exponent of instantaneous growth of herring should be greater than -0.4. Allometry of herring mortality implies that year-class strength of herring should be positively correlated with size at recruitment. 78 refs., 1 fig., 1 tab.

    To determine the effects of different prognostic factors, including previous antiplatelet therapy, admission data, and radiographic findings on discharge and 3-month neurological condition using modified Rankin scale (mRS) and mortality at 30 days and 3-month follow-up in patients presenting to the emergency department with spontaneous intracranial hemorrhage (sICH). Between January and July 2012, 120 consecutive patients (males 62%, females 38%), who were admitted within 48 h of symptoms onset, were included. We recorded the following data on admission: demographics; functional scores of ICH, Glasgow Coma Scale, and National Institutes of Health Stroke Scale; vital signs; smoking status; use of illicit drug; preadmission antiplatelet treatment; results of laboratory tests (platelet count, serum glucose, sodium and creatinine levels, and prothrombin time); and primary neuroimaging findings [intraventricular hemorrhage (IVH), midline shift, and hydrocephalus]. In multivariate analysis using adjusted model for demographics and prior antiplatelet therapy; functional scores, laboratory results, and diabetes history correlated with mortality during 30 days after the event. Moreover, the parameters on the initial computed tomography scan significantly increased 30-day fatality rate and was correlated with increase in the discharge mRS score of survivors. The odds ratio (OR) and 95% confidence interval (CI) of early mortality associated with IVH presentation was 2.34 (CI 1.76-3.02, p = 0.003). The corresponding ORs in those with midline shift displacement and hydrocephalus were 2.18 (95% CI 2.08-3.80, p = 0.01) and 1.62 (95% CI 1.01-2.63, p = 0.02), respectively. In patients with ICH, prognostic factors, include various clinical parameters and paraclinical findings of admission time. PMID:23543380

    There is a paucity of data describing acute kidney injury (AKI) following transcatheter aortic valve implantation and its impact on mortality remains unknown. We therefore evaluate the incidence, predictors and impact of AKI following transcatheter aortic valve implantation. We searched MEDLINE for studies from 2008 to 2013, evaluating AKI after transcatheter aortic valve implantation. All studies were compared according to the incidence, predictors and impact of AKI following transcatheter aortic valve implantation. AKI was diagnosed according to the Valve Academic Research Consortium definition using the RIFLE criteria. Thirteen studies with more than 1900 patients were included. AKI occurred in 8.3-57% of the patients. The following factors were associated with AKI: blood transfusion; transapical access; preoperative creatinine concentration; peripheral vascular disease; hypertension; and procedural bleeding events. The 30-day mortality rate in patients with AKI ranged from 13.3% to 44.4% and was 2-6-fold higher than in patients without AKI. The amount of contrast agent used was not associated with the occurrence of AKI. AKI is a common complication, with an incidence of 8.3-57% following transcatheter aortic valve implantation. Patients with AKI had higher 30-day and late mortality rates. However, AKI was related to the amount of contrast volume used in only one study. PMID:24556191

    Substance P (SP), a member of tachykinin family, is involved in the inflammation of the central nervous system and in the appearance of cerebral edema. Higher serum levels of SP have been found in 18 patients with cerebral ischemia compared with healthy controls. The aim of our multi-center study was to analyze the possible association between serum levels of SP and mortality in ischemic stroke patients. We included patients with malignant middle cerebral artery infarction (MMCAI) and a Glasgow Coma Scale (GCS) lower than 9. Non-surviving patients at 30 days (n = 31) had higher serum concentrations of SP levels at diagnosis of severe MMCAI than survivors (n = 30) (p < 0.001). We found in multiple regression an association between serum concentrations of SP higher than 362 pg/mL and mortality at 30 days (Odds Ratio = 5.33; 95% confidence interval = 1.541-18.470; p = 0.008) after controlling for age and GCS. Thus, the major novel finding of our study was the association between serum levels of SP and mortality in patients suffering from severe acute ischemic stroke. PMID:27338372

Previous meta-regressions have estimated that a procedure-related delay of 60 minutes would nullify the benefits of PPCI on mortality. Using a combined database from randomized clinical trials and registries (n = 2,781) and an independently developed model of mortality risk in STEMI, we developed logistic regression models predicting 30-day mortality for PPCI and thrombolysis by examining the influence of baseline risk on the treatment effect of PPCI and on the hazard of treatment delay. We used these models to solve mathematically for "time interval to mortality equivalence," defined as the PPCI-related delay that would nullify its expected mortality benefit over thrombolysis, and to explore the influence of baseline risk on this value. As baseline risk increases, the relative benefit of PPCI compared with thrombolytic therapy significantly increases (p = 0.002); patients with STEMI at relatively low risk of mortality accrue little or no incremental mortality benefit from PPCI, but high-risk patients benefit greatly. However, as baseline risk increases, the hazard associated with longer treatment-related delay also increases (p = 0.007). These 2 effects are compensatory and yield a roughly uniform time interval to mortality equivalence of approximately 100 minutes in patients who have at least a moderate degree of mortality risk (> approximately 4%). In conclusion, the mortality benefits of PPCI and the hazard of PPCI-related delay depend on baseline risk. Previous meta-regressions appear to have underestimated the PPCI-related delay that would nullify the incremental benefits of PPCI. PMID:17493465

    The firm is a fundamental economic unit of contemporary human societies. Studies on the general quantitative and statistical character of firms have produced mixed results regarding their lifespans and mortality. We examine a comprehensive database of more than 25 000 publicly traded North American companies, from 1950 to 2009, to derive the statistics of firm lifespans. Based on detailed survival analysis, we show that the mortality of publicly traded companies manifests an approximately constant hazard rate over long periods of observation. This regularity indicates that mortality rates are independent of a company's age. We show that the typical half-life of a publicly traded company is about a decade, regardless of business sector. Our results shed new light on the dynamics of births and deaths of publicly traded companies and identify some of the necessary ingredients of a general theory of firms. PMID:25833247

    Immunological failure may be the cause of predisposition to certain infections, neoplasms, and vascular diseases in adulthood. Mortality risks through life may reflect an undetermined number of causes. This study describes the prevalence of positivity of autoantibodies through life, along with general and specific mortality causes in three countries with different socioeconomic development (Guatemala, Mexico and the United States). Prevalence of autoantibodies by age was obtained from previous reports. In spite of having involved different ethnic groups, the observed trends in prevalence of autoantibodies, as well as mortality through life, showed a similar behavior. Thus, both the increase in autoantibody production and death risk as age rises, may share physiopathological phenomena related to the ageing process. PMID:7539882

    This paper describes a research study to investigate the efficacy of peppermint oil as a treatment for postoperative nausea. It uses a three-condition experimental design using statistical analysis to compare groups. The Kruskal-Wallis test was used to establish significance and the Mann-Whitney test to differentiate significance between the groups. The control, placebo and experimental groups of gynaecological patients were compared, using variables known to affect postoperative nausea. They were found to be homogeneous for the purposes of the study. A statistically significant differences was demonstrated on the day of operation, using the Kruskal-Wallis test, P = 0.0487. Using the Mann-Whitney test the difference was shown to be between the placebo and experimental group (U = 3; P = 0.02). The experimental group also required less traditional antiemetics and received more opioid analgesia postoperatively. The total cost of the treatment was 48 pence per person. PMID:9378876

    Good pain control after surgery is important to prevent negative outcomes such as tachycardia, hypertension, myocardial ischemia, decrease in alveolar ventilation, and poor wound healing. Exacerbations of acute pain can lead to neural sensitization and release of mediators both peripherally and centrally. Clinical wind up occurs from the processes of N-Methyl D-Aspartate (NMDA) activation, wind up central sensitization, long-term potentiation of pain (LTP), and transcription-dependent sensitization. Advances in the knowledge of molecular mechanisms have led to the development of multimodal analgesia and new pharmaceutical products to treat postoperative pain. The new pharmacological products to treat postoperative pain include extended-release epidural morphine and analgesic adjuvants such as capsaicin, ketamine, gabapentin, pregabalin dexmetomidine, and tapentadol. Newer postoperative patient-controlled analgesia (PCA) in modes such as intranasal, regional, transdermal, and pulmonary presents another interesting avenue of development. PMID:20351978

    Advances in orthopedic and arthroscopic surgical procedures of the knee such as, knee replacement, ligamentous reconstruction as well as articular cartilage and meniscus repair techniques have resulted in a significant increase in the number of patients undergoing knee arthroscopy or open surgery. As a consequence postoperative MR imaging examinations increase. Comprehensive knowledge of the normal postoperative MR imaging appearances and abnormal findings in the knee associated with failure or complications of common orthopedic and arthroscopic surgical procedures currently undertaken is crucial. This article reviews the various normal and pathological postoperative MR imaging findings following anterior and posterior cruciate ligament, medial collateral ligament and posterolateral corner reconstruction, meniscus and articular cartilage surgery as well as total knee arthroplasty with emphasis on those surgical procedures which general radiologists will likely be faced in their daily clinical routine.

    Disease recurrence following resective surgery for Crohn disease remains a challenging clinical problem, and more studies are needed to better define risk stratification and treatment recommendations in the postoperative setting. Endoscopy remains the gold standard for the assessment of postoperative disease recurrence, and all Crohn disease patients who undergo surgery should undergo ileocolonoscopy within 6 to 12 months of surgery. The degree of endoscopic recurrence in the neoterminal ileum during this procedure provides prognostic information regarding the severity of the future disease course. WCE, MRE, and SICUS are all promising noninvasive modalities to assess for postoperative Crohn disease activity. However, further studies are needed to better define scoring systems, operating characteristics and variability, and prognostic data for each of these modalities. In patients at risk for early disease recurrence, more aggressive prophylactic therapy should be considered, in hopes of delivering true “top-down” therapy that may offer maximum impact in altering the natural history of Crohn disease.

    Perioperative lymphopenia has been linked with an increased risk of postoperative infectious complications, but the mechanisms remain unclear. We tested the hypothesis that bioenergetic dysfunction is an important mechanism underlying lymphopenia, impaired functionality and infectious complications. In two cohorts of patients (61-82 years old) undergoing orthopaedic joint replacement (n=417 and 328, respectively), we confirmed prospectively that preoperative lymphopenia (≤1.3 x 10(9)·l(-1); <20% white cell count; prevalence 15-18%) was associated with infectious complications (relative risk 1.5 (95% confidence interval 1.1-2.0); P=0.008) and prolonged hospital stay. Lymphocyte respirometry, mitochondrial bioenergetics and function were assessed (n=93 patients). Postoperative lymphocytes showed a median 43% fall (range: 26-65%; P=0.029; n=13 patients) in spare respiratory capacity, the extra capacity available to produce energy in response to stress. This was accompanied by reduced glycolytic capacity. A similar hypometabolic phenotype was observed in lymphocytes sampled preoperatively from chronically lymphopenic patients (n=21). This hypometabolic phenotype was associated with functional lymphocyte impairment including reduced T-cell proliferation, lower intracellular cytokine production and excess apoptosis induced by a range of common stressors. Glucocorticoids, which are ubiquitously elevated for a prolonged period postoperatively, generated increased levels of mitochondrial reactive oxygen species, activated caspase-1 and mature interleukin (IL)-1β in human lymphocytes, suggesting inflammasome activation. mRNA transcription of the NLRP1 inflammasome was increased in lymphocytes postoperatively. Genetic ablation of the murine NLRP3 inflammasome failed to prevent glucocorticoid-induced lymphocyte apoptosis and caspase-1 activity, but increased NLRP1 protein expression. Our findings suggest that the hypometabolic phenotype observed in chronically lymphopenic

    Examination of blood serum and cellular elements of 45 patients with postoperative diffuse purulent peritonitis shows that in the majority of examined persons before and in the first days after the operation immunodepression exists. The dynamics of immunologic disturbances (antibody titers, phagocytosis, immunoglobulines, T- and B-lymphocytes) are sufficiently informative and as a rule, correlate with clinical course of peritonitis. Adequate reaction of the organism to infection resulted in a favourable outcome. Low values of immunologic indices in postoperative period necessitate the use of stimulant therapy in combined treatment of this complication. PMID:9916429

    IMPORTANCE Thousands of physicians attend scientific meetings annually. Although hospital physician staffing and composition may be affected by meetings, patient outcomes and treatment patterns during meeting dates are unknown. OBJECTIVE To analyze mortality and treatment differences among patients admitted with acute cardiovascular conditions during dates of national cardiology meetings compared with nonmeeting dates. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of 30-day mortality among Medicare beneficiaries hospitalized with acute myocardial infarction (AMI), heart failure, or cardiac arrest from 2002 through 2011 during dates of 2 national cardiology meetings compared with identical nonmeeting days in the 3 weeks before and after conferences (AMI, 8570 hospitalizations during 82 meeting days and 57 471 during 492 nonmeeting days; heart failure, 19 282 during meeting days and 11 4591 during nonmeeting days; cardiac arrest, 1564 during meeting days and 9580 during nonmeeting days). Multivariable analyses were conducted separately for major teaching hospitals and nonteaching hospitals and for low-and high-risk patients. Differences in treatment utilization were assessed. EXPOSURES Hospitalization during cardiology meeting dates. MAIN OUTCOMES AND MEASURES Thirty-day mortality, procedure rates, charges, length of stay. RESULTS Patient characteristics were similar between meeting and nonmeeting dates. In teaching hospitals, adjusted 30-day mortality was lower among high-risk patients with heart failure or cardiac arrest admitted during meeting vs nonmeeting dates (heart failure, 17.5% [95% CI, 13.7%–21.2%] vs 24.8% [95% CI, 22.9%–26.6%]; P < .001; cardiac arrest, 59.1% [95% CI, 51.4%–66.8%] vs 69.4% [95% CI, 66.2%–72.6%]; P = .01). Adjusted mortality for high-risk AMI in teaching hospitals was similar between meeting and nonmeeting dates (39.2% [95% CI, 31.8%–46.6%] vs 38.5% [95% CI, 35.0%–42.0%]; P = .86), although adjusted percutaneous

    Epidemiologic evidence suggested chronic obstructive pulmonary disease (COPD) might increase risk for abdominal aortic aneurysm (AAA). However, the association between COPD and AAA remains inconclusive. We searched PubMed and Cochrane databases until June 2015. Forty-eight articles were included for meta-analysis. COPD was found to be positively associated with AAA, regardless of study design and smoking status. AAA mortality is higher among COPD patients compared with non-COPD patients (postoperative [adjusted OR 2.11; 95% CI 1.33–3.34]; long-term [adjusted OR 1.70; 95% CI 1.37–2.12]). But the association between postoperative mortality and COPD was not found to be significant in patients underwent endovascular aneurysm repair (mixed OR 2.53; 95% CI 0.70–9.18). Rupture AAA may increase the postoperative mortality in COPD patients (rupture [adjusted OR 4.75; 95% CI 2.07–10.89]; non-rupture [adjusted OR 1.97; 95% CI 1.11–3.49]). The AAA postoperative morbidity was found to be positively associated with COPD (adjusted OR 1.59; 95% CI 1.14–2.21). Increased COPD severity may increase the long-term mortality (medical versus oxygen dependent: [OR 1.26; 95% CI 1.07–1.49] versus [OR 2.79; 95% CI 2.24–3.49]). In conclusion, COPD may increase the risk of AAA, morbidity and mortality of AAA patients underwent endovascular aortic repair. PMID:27112336

    Open surgical repair (OSR) is a conventional surgical method used in the repair a ruptured abdominal aortic aneurysm (AAA); however, OSR results in high perioperative mortality rates. The level of serum angiotensin-converting enzyme 2 (ACE2) has been reported to be an independent risk factor for postoperative in-hospital mortality following major cardiopulmonary surgery. In the present study, the association of serum ACE2 levels with postoperative in-hospital mortality was investigated in patients undergoing OSR for ruptured AAA. The study enrolled 84 consecutive patients underwent OSR for ruptured AAA and were subsequently treated in the intensive care unit. Patients who succumbed postoperatively during hospitalization were defined as non-survivors. Serum ACE2 levels were measured in all patients prior to and following the surgery using ELISA kits. The results indicated that non-survivors showed significantly lower mean preoperative and postoperative serum ACE2 levels when compared with those in survivors. Multivariate logistic regression analysis also showed that, subsequent to adjusting for potential confounders, the serum ACE2 level on preoperative day 1 showed a significant negative association with the postoperative in-hospital mortality. This was confirmed by multivariate hazard ratio analysis, which showed that, subsequent to adjusting for the various potential confounders, the risk of postoperative in-hospital mortality remained significantly higher in the two lowest serum ACE2 level quartiles compared with that in the highest quartile on preoperative day 1. In conclusion, the present study provided the first evidence supporting that the serum ACE2 level is an independent risk factor for the in-hospital mortality following OSR for ruptured AAA. Furthermore, low serum ACE2 levels on preoperative day 1 were found to be associated with increased postoperative in-hospital mortality. Therefore, the serum ACE2 level on preoperative day 1 may be a potential

    Background XaraColl, a collagen-based implant that delivers bupivacaine to sites of surgical trauma, has been shown to reduce postoperative pain and use of opioid analgesia in patients undergoing open surgery. We therefore designed and conducted a preliminary feasibility study to investigate its application and ease of use for laparoscopic surgery. Methods We implanted four XaraColl implants each containing 50 mg of bupivacaine hydrochloride (200 mg total dose) in ten men undergoing laparoscopic inguinal or umbilical hernioplasty. Postoperative pain intensity and use of opioid analgesia were recorded through 72 hours for comparison with previously reported data from efficacy studies performed in men undergoing open inguinal hernioplasty. Safety was assessed for 30 days. Results XaraColl was easily and safely implanted via a laparoscope. The summed pain intensity and total use of opioid analgesia through the first 24 hours were similar to the values observed in previously reported studies for XaraColl-treated patients after open surgery, but were lower through 48 and 72 hours. Conclusion XaraColl is suitable for use in laparoscopic surgery and may provide postoperative analgesia in laparoscopic patients who often experience considerable postoperative pain in the first 24–48 hours following hospital discharge. Randomized controlled trials specifically to evaluate its efficacy in this application are warranted. PMID:23390367

    Ventricular dyssynchrony is associated with morbidity and mortality after palliation of a single ventricle. The authors hypothesized that resynchronization with optimized temporary multisite pacing postoperatively would be safe, feasible, and effective. Pacing was assessed in the intensive care unit within the first 24 h after surgery. Two unipolar atrial pacing leads and four bipolar ventricular pacing leads were placed at standardized sites intraoperatively. Pacing was optimized to maximize mean arterial pressure. The protocol tested 11 combinations of the 4 different ventricular lead sites, 6 atrioventricular delays (50-150 ms), and 14 intraventricular delays. Optimal pacing settings were thus determined and ultimately compared in four configurations: bipolar, unipolar, single-site atrioventricular pacing, and intrinsic rhythm. Each patient was his or her own control, and all pacing comparisons were implemented in random sequence. Single-ventricle palliation was performed for 17 children ages 0-21 years. Pacing increased mean arterial pressure (MAP) versus intrinsic rhythm, with the following configurations: bipolar multisite pacing increased MAP by 2.2 % (67.7 ± 2.4 to 69.2 ± 2.4 mmHg; p = 0.013) and unipolar multisite pacing increased MAP by 2.8 % (67.7 ± 2.4 to 69.6 ± 2.7 mmHg; p = 0.002). Atrioventricular single-site pacing increased MAP by 2.1 % (67.7 ± 2.4 to 69.1 ± 2.5 mmHg: p = 0.02, insignificant difference under Bonferroni correction). The echocardiographic fractional area change in nine patients increased significantly only with unipolar pacing (32 ± 3.1 to 36 ± 4.2 %; p = 0.02). No study-related adverse events occurred. Multisite pacing optimization is safe and feasible in the early postoperative period after single-ventricle palliation, with improvements in mean arterial pressure and fractional area shortening. Further study to evaluate clinical benefits is required. PMID:24827078

    Mexico's infant mortality rate is estimated to have declined from 189 in 1930 to 129 in 1950 and 30 in 1995. The infant mortality rate has continued its decline despite the economic crisis of recent years. The use of oral rehydration therapy has reduced mortality from diarrhea, and the spread of family planning has reduced the numbers of births at high risk due to maternal age, parity, or short birth intervals. The types of causes of infant death have changed as the numbers have decreased. They can be grouped in ascending order according to the difficulty of prevention: diseases preventable by immunization, acute diarrhea, acute respiratory infections, perinatal disorders, and congenital anomalies. Over two-thirds of infant deaths recorded since 1950 have been due to these causes. Infectious diseases, including diarrhea, acute respiratory infections, and conditions preventable by immunization predominated as causes of infant mortality before 1930. As the epidemiological transition progresses, diseases preventable by immunization lose importance, and diarrhea and respiratory infections occupy the first two places, with perinatal disorders being third. Between 1980 and 1990, in Mexico, diarrhea and acute respiratory infections dropped to second and third place after perinatal disorders, with congenital anomalies in fourth place. In most developed countries, perinatal disorders and congenital anomalies are the two most frequent causes of death, while diarrhea and respiratory infections no longer appear in the top five. In 1995, the four main causes in Mexico in descending order were perinatal disorders, congenital anomalies, acute respiratory infections, and diarrhea. PMID:12158082

    A brief analysis of data from the records of the Government Hospital for Women and Children in Madras for a 36-year period (1929-1964) is presented. India with a population of over 550 million has only 1 doctor for each 6000 population. For the 80% of the population which is rural, the doctor ratio is only 88/1 million. There is also a shortage of paramedical personnel. During the earlier years of this study period, abortions, puerperal infections; hemorrhage, and toxemia accounted for nearly 75% of all meternal deaths, while in later years deaths from these causes were 40%. Among associated factors in maternal mortality, anemia was the most frequent, it still accounts for 20% and is a contributory factor in another 20%. The mortality from postpartum hemorrhage was 9.3% but has now decreased to 2.8%. Eclampsia is a preventable disease and a marked reduction in maternal and perinatal mortality from this cause has been achieved. Maternal deaths from puerperal infections have dropped from 25% of all maternal deaths to 7%. Uterine rupture has been reduced from 75% to 9.3% due to modern facilities. Operative deliveries still have an incidence of 2.1% and a mortality rate of 1.4% of all deliveries. These rates would be further reduced by more efficient antenatal and intranatal care. Reported perinatal mortality of infants has been reduced from 182/1000 births to an average of 78/1000 in all areas, but is 60.6/1000 in the city of Madras. Socioeconomic standards play an important role in perinatal mortality, 70% of such deaths occurring in the lowest economic groups. Improvement has been noted in the past 25 years but in rural areas little progress has been made. Prematurity and low birth weights are still larger factors in India than in other countries, with acute infectious diseases, anemia, and general malnutrition among mothers the frequent causes. Problems requiring further efforts to reduce maternal and infant mortality are correct vital statistics, improved

    Preston, S H

    1985-01-01

    This paper attempts to update results reported in 2 earlier papers about the role of socioeconomic factors in worldwide mortality declines since the 1930s. Preston (1975) demonstrated that the relationship between life expectancy at birth and per capita income (in constant dollars) had shifted between the 1930s and the 1960s. A country at a particular level of national income per capita was estimated to have a level of life expectancy at birth that was, on average, 9.7 years higher in the 1960s than it would have been in the 1930s at the same level of income. That shift clearly was attributable to factors other than measured income gains. To identify the contribution of advances in literacy and nutrition to the apparent shift, Preston (1980) added those variables to income in regression equations estimated with data on 36 countries around 1940 and 120 countries around 1970. For the less developed countries (LDCs), the shift in the relationship between 1940-70 was estimated to be 8.8 years after those variables were introduced along with income. Thus, literacy and nutritional gains were responsible for relatively little of the shift. The goal here is to estimate the amount of shift in the relation between mortality and other development indicators during the 1965-69 to 1975-79 period. The focus is on the 70% of the developing world (exclude China) where, in the aggregate, there are indications of a slowdown in the pace of mortality change during the 1960s and the early 1970s. In all cases a mortality indicator was used as the dependent variable in a cross-national regression analysis that includes data from LDCs and from developed countries. Also, in all cases, the set of independent variables included some transformation of the following: the percentage of adults who were literate, gross domestic product per capita in constant dollars, and the excess of per capita daily calories supplied above 1500. Data were drawn from the standard UN, UNESCO, and World Bank

    Background. In older adults admitted to intensive care units (ICUs), frailty influences prognosis. We examined the relationship between the frailty index (FI) based on deficit accumulation and early and late survival. Methods. Older patients (≥65 years) admitted to a specialized geriatric ICU at the Liuhuaqiao Hospital, Guangzhou, China between July–December 2011 (n = 155; age 82.7±7.1 y; 87.1% men) were followed for 300 days. The FI was calculated as the proportion present of 52 health deficits. FI performance was compared with that of several prognostic scores. Results. The 90-day death rate was 38.7% (n = 60; 27 died within 30 days). The FI score was correlated with the Glasgow Coma Scale, Karnofsky Scale, Palliative Performance Scale, Acute Physiology Score—APACHE II and APACHE IV (r 2 = 0.52 to 0.72, p < 0.001). Patients who died within 30 days had higher mean FI scores (0.41±0.11) than those who survived to 300 days (0.22±0.11; F = 38.91, p < 0.001). Each 1% increase in the FI from the previous level was associated with an 11% increase in the 30-day mortality risk (95% CI: 7%–15%) adjusting for age, sex, and the prognostic scores. The FI discriminated patients who died in 30 days from those who survived with moderately high accuracy (AUC = 0.89±0.03). No one with an FI score >0.46 survived past 90 days. Conclusion. ICU survival was strongly associated with the level of frailty at admission. An FI based on health deficit accumulation may help improve critical care outcome prediction in older adults.

    The purpose of this study was to assess the incidence and risk factors associated with postoperative nausea (PON) and vomiting (POV) after orthognathic surgery. A review of the clinical records of consecutively enrolled subjects (2008–2012) at a single academic institution was conducted between 9/2013 and 3/2014. Data on the occurrence of PON and POV and potential patient-related, intraoperative, and postoperative explanatory factors were extracted from the medical records. Logistic models were used for the presence/absence of postoperative nausea and vomiting separately. Data from 204 subjects were analyzed: 63% were female, 72% Caucasian, and the median age was 19 years. Thirty-three percent had a mandibular osteotomy alone, 27% a maxillary osteotomy alone, and 40% had bimaxillary osteotomies. Sixty-seven percent experienced PON and 27% experienced POV. The most important risk factors for PON in this series were female gender, increased intravenous fluids, and the use of nitrous oxide, and for POV were race, additional procedures, and morphine administration. The incidence of PON and POV following orthognathic surgery in the current cohort of patients, after the introduction of the updated 2007 consensus guidelines for the management of postoperative nausea and vomiting, has not decreased substantially from that reported in 2003–2004.

    30 postoperative patients, who had undergone abdominal gynaecological surgery with standard general anaesthesia were randomly divided into three groups and received, in the recovery ward, a continuous infusion of either pentazocine, piritramid, or ketamine. The patients rated their pain on a 15 cm pain analogue score. Group I pentazocine: Mean dosage on the day of operation 0.12 mg/kg/h, 0.1 mg/kg/h on the first and only 0.07 mg/kg/h on the second postoperative day. Pentazocine blood levels were on average 50 micrograms/l. Group II piritramid: Mean dosage on the day of operation 0.038 mg/kg/h, 0.024 mg/kg/h on the first and 0.019 mg/kg/h on the second postoperative day. Blood levels of piritramid were not determined because there is no satisfactory assay available. Group III ketamine: mean dosage on the day of operation 0.32 mg/kg/h, 0.28 mg/kg/h on the first and 0.29 mg/kg/h on the second postoperative day. Ketamine blood levels lay between 120 and 180 micrograms/l. The three analgesics did not cause any important haemodynamic or respiratory side effects. Pentazocine and piritramid were the most effective analgesics, ketamine was the least effective with a high incidence of side effects. PMID:6412586

    Postoperative sore throat has a reported incidence of up to 62% following general anaesthesia. In adults undergoing tracheal intubation, female sex, younger age, pre-existing lung disease, prolonged duration of anaesthesia and the presence of a blood-stained tracheal tube on extubation are associated with the greatest risk. Tracheal intubation without neuromuscular blockade, use of double-lumen tubes, as well as high tracheal tube cuff pressures may also increase the risk of postoperative sore throat. The expertise of the anaesthetist performing tracheal intubation appears to have no influence on the incidence in adults, although it may in children. In adults, the i-gel(™) supraglottic airway device results in a lower incidence of postoperative sore throat. Cuffed supraglottic airway devices should be inflated sufficiently to obtain an adequate seal and intracuff pressure should be monitored. Children with respiratory tract disease are at increased risk. The use of supraglottic airway devices, oral, rather than nasal, tracheal intubation and cuffed, rather than uncuffed, tracheal tubes have benefit in reducing the incidence of postoperative sore throat in children. Limiting both tracheal tube and supraglottic airway device cuff pressure may also reduce the incidence. PMID:27158989

    Delirium is a common postoperative surgical complication associated with poor outcomes. The complexity of delirium demands that each patient be assessed individually and a tailored prevention and treatment regimen be put in place. Nonpharmacologic and pharmacologic strategies are available to achieve this goal. PMID:24721366

    The value of immediate postoperative enteral hyperalimentation with an elemental diet (high nitrogen Vivonex, full strength) at 125 cc per hour for 4 days was assessed in patients after radical urological surgery. Of 32 patients studied 21 received an elemental diet using a Vivonex Moss tube, which is a 3-lumen tube with esophagogastric decompression and simultaneous duodenal feeding, and the remaining 11 had a nasogastric tube only without nutritional support. We have used a selected group of parameters, including serum albumin, serum transferrin, creatinine height index, weight loss, total lymphocyte count, nitrogen balance and plasma fibronectin. All patients in the Moss tube group approached or achieved positive nitrogen balance by 4 days postoperatively, whereas the nasogastric tube group remained in negative nitrogen balance. Postoperative paralytic ileus was prevented in the majority of patients in the Moss tube group while receiving full nutritional support. We have found that the use of the Moss tube is a reasonable approach for postoperative alimentation. The tube is relatively easy to insert and well tolerated, and its use is a less expensive alternative to parenteral hyperalimentation. PMID:6427479

    Potent systemic (narcotic) analgesics, when given in doses sufficient to produce ample pain relief, usually also produce mental and respiratory depression and, at times, circulatory impairment, that prolong postoperative morbidity. Complications due to morphine sulfate or meperidine hydrochloride can be minimized by titrating the patient's pain with small intravenous doses of narcotics (morphine sulfate, 2 to 3 mg, or meperidine hydrochloride, 15 to 25 mg) administered slowly at 15- to 20-minute intervals until the pain is relieved. On the third or fourth postoperative day, acetaminophen tablets usually suffice to provide relief of pain with little or no risk to patients. Continuous segmental epidural block or intercostal block, with or without splanchnic block, provide excellent pain relief that, in contrast to the narcotic, is complete. These are especially useful after operations on the chest or abdomen or the lower extremity. Regional analgesia is especially indicated in patients not adequately relieved from severe postoperative pain with narcotics, or when these drugs are contraindicated by advanced pulmonary, renal, or hepatic disease. Continuous caudal analgesia is also effective to completely releive severe postoperative pain in the lower limbs and perineum. PMID:871249

    BACKGROUND: Incidence of postoperative pulmonary complications (PPC) in patients undergoing non-cardiothoracic surgery remains high and the occurrence of these complications has enormous implications for the patient and the health care system. AIM: The aim of the study was to identify risk factors for PPC in patients undergoing abdominal surgical procedures. MATERIALS AND METHODS: A prospective cohort study in abdominal surgical patients, admitted to the emergency and surgical ward of the UHC of Tirana, Albania, was conducted during the period: March 2014-March 2015. We collected data on the occurrence of a symptomatic and clinically significant PPC using clinical, laboratory, and radiology data. We evaluated the relations between PPCs and various pre-operative or intra-operative factors to identify risk factors. RESULTS: A total of 450 postoperative patients admitted to the surgical emergency and surgical ward were studied. The mean age were 59.85 ±13.64 years with 59.3% being male. Incidence of PPC was 27.3% (123 patients) and hospital length of stay was 4.93 ± 4.65 days. Length of stay was substantially prolonged for those patients who developed PPC (7.48 ± 2.89 days versus 3.97± 4.83 days, p < 0.0001. PPC were identified as risk factors for mortality, OR: 21.84; 95% CI: 11.66-40.89; P < 0.0001. The multivariate regression analysis identified as being independently associated with an increased risk of PPC: age ≥ 65 years (OR 11.41; 95% CI: 4.84-26.91, p < 0.0001), duration of operation ≥ 2.5 hours (OR 8.38; 95% CI: 1.52-46.03, p = 0.01, history of previous pulmonary diseases (OR 11.12; 95% CI: 3.28-37.65, P = 0.0001) and ASA > 2 (OR 6.37; 95% CI: 1.54-26.36, P = 0.01). CONCLUSION: We must do some efforts in reducing postoperative pulmonary complications, firstly to identify which patients are at increased risk, and then following more closely high-risk patients because those patients are most likely to benefit.

    Right ventricular (RV) dysfunction in acute respiratory distress syndrome (ARDS) contributes to increased mortality. Our aim is to identify reproducible transthoracic echocardiography (TTE) parameters of RV dysfunction that can be used to predict outcomes in ARDS. We performed a retrospective single-center cohort pilot study measuring tricuspid annular plane systolic excursion (TAPSE), Tei index, RV-fractional area change (RV-FAC), pulmonary artery systolic pressure (PASP), and septal shift, reevaluated by an independent blinded cardiologist (JK). Thirty-eight patients were included. Patients were divided on the basis of 30-day survival. Thirty-day mortality was 47%. Survivors were younger than nonsurvivors. Survivors had a higher pH, PaO2∶FiO2 ratio, and TAPSE. Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II), and Sequential Organ Failure Assessment (SOFA) scores were lower in survivors. TAPSE has the strongest association with increased 30-day mortality from date of TTE. Accordingly, TAPSE has a strong positive correlation with PaO2∶FiO2 ratios, and Tei index has a strong negative correlation with PaO2∶FiO2 ratios. Septal shift was associated with lower PaO2∶FiO2 ratios. Decrease in TAPSE, increase in Tei index, and septal shift were seen in the severe ARDS group. In multivariate logistic regression models, TAPSE maintained a significant association with mortality independent of age, pH, PaO2∶FiO2 ratios, positive end expiratory pressure, PCO2, serum bicarbonate, plateau pressures, driving pressures, APACHE II, SAPS II, and SOFA scores. In conclusion, TAPSE and other TTE parameters should be used as novel predictive indicators for RV dysfunction in ARDS. These parameters can be used as surrogate noninvasive RV hemodynamic measurements to be manipulated to improve mortality in patients with ARDS and contributory RV dysfunction. PMID:27252840

    Accessory gene regulator (agr) dysfunction in Staphylococcus aureus has been associated with a longer duration of bacteremia. We aimed to assess the independent association between agr dysfunction in S. aureus bacteremia and 30-day in-hospital mortality. This retrospective cohort study included all adult inpatients with S. aureus bacteremia admitted between 1 January 2003 and 30 June 2007. Severity of illness prior to culture collection was measured using the modified acute physiology score (APS). agr dysfunction in S. aureus was identified semiquantitatively by using a δ-hemolysin production assay. Cox proportional hazard models were used to measure the association between agr dysfunction and 30-day in-hospital mortality, statistically adjusting for patient and pathogen characteristics. Among 814 patient admissions complicated by S. aureus bacteremia, 181 (22%) patients were infected with S. aureus isolates with agr dysfunction. Overall, 18% of patients with agr dysfunction in S. aureus died, compared to 12% of those with functional agr in S. aureus (P = 0.03). There was a trend toward higher mortality among patients with S. aureus with agr dysfunction (adjusted hazard ratio [HR], 1.34; 95% confidence interval [CI], 0.87 to 2.06). Among patients with the highest APS (scores of >28), agr dysfunction in S. aureus was significantly associated with mortality (adjusted HR, 1.82; 95% CI, 1.03 to 3.21). This is the first study to demonstrate an independent association between agr dysfunction and mortality among severely ill patients. The δ-hemolysin assay examining agr function may be a simple and inexpensive approach to predicting patient outcomes and potentially optimizing antibiotic therapy. PMID:21173172
