Impact of frailty and atrial fibrillation in elderly patients with acute coronary syndromes.

There is scarce information on the prognostic role of frailty and atrial fibrillation (AF) in elderly patients with acute coronary syndrome (ACS). The aim was to analyse the management of elderly patients with frailty and AF who suffered an ACS using data of the prospective multicentre LONGEVO-SCA registry. We evaluated the predictive performance of FRAIL, Charlson scores and AF status for adverse events at 6-month follow-up. A total of 531 unselected patients with ACS and above 80years old [mean age 84.4 (SD=3.6) years; 322 (60.6%) male] were enrolled, of whom 128 (24.1%) with AF and 145 (27.3%) with frailty. Mutually exclusive number of patients were as follows: non-frail and sinus rhythm (SR) 304 (57.2%); frail and SR 99 (18.6%); non-frail and AF 82 (15.4%); and frail and AF 46 (8.7%). Frail and AF patients compared with non-frail and SR patients had higher risk of all-cause mortality [HR 2.61, (95% CI 1.28-5.31; P=.008)], readmissions [HR 2.28, (95%CI 1.37-3.80); P=.002)] and its composite [HR 2.28, (95% CI 1.44-3.60); P<.001)]. After multivariate adjustment, FRAIL score [HR 1.41, (95% CI 1.02-1.97); P=.040] and Charlson index [HR 1.32, (95% CI 1.09-1.59); P=.003] were significantly associated with mortality. AF status was not independently related with adverse events. Frailty but not AF status was independently associated with follow-up adverse events. Frailty status and high Charlson index were independent conditions associated with adverse events during the follow-up. The impact of functional status has a bigger prognostic role over AF status in elderly patients with ACS.

Enoxaparina en el tratamiento de la tromboembolia venosa: estudio observacional de práctica clínica habitual

IntroductionThere are various types of low molecular weight heparins with different dosages for the treatment of venous thromboembolism (VTE). Material and methodsMulticentre observational-retrospective study including patients with VTE treated with enoxaparin and followed for one year. Patients were divided into 2groups: hospital and outpatient. The objective of the study was to describe the use of 2enoxaparin dosages (150 IU/kg per day and 100 IU/kg per 12hours) in the treatment of VTE in the 2groups. ResultsA total of 896 patients were included: 44.5% initiated enoxaparin in hospital and 55.6% as outpatients. The hospital patients compared with outpatients were older (69.6 vs. 66.1 years), had a higher Charlson index (3.0 vs. 2.5), and more pulmonary embolism (63.1 vs. 5.8%), and antiplatelet agent (68.8 vs. 51.4%) and corticosteroid use (25.1 vs. 13.7%). The dosage was once a day in 78.3% and twice a day in 21.7% of patients, with no between-group differences. Mean treatment duration (84.7 vs. 59.1 days) was higher in the hospital patients. The percentage of patients in whom the dosage was modified (22.6 vs. 20.9%) was similar between groups. Patients with VTE and cancer were mostly outpatients and received enoxaparin once a day. ConclusionsThe once-a-day dosage was the most widely used in both hospital patients and outpatients. In one fifth of patients, the enoxaparin dosage was modified during follow up.

Risk factors for major adverse cardiovascular events after the first acute coronary syndrome

Aims To evaluate risk factors for major adverse cardiac event (MACE) after the first acute coronary syndrome (ACS) and to examine the prevalence of risk factors in post-ACS patients. Methods We used Finnish population-based myocardial infarction register, FINAMI, data from years 1993–2011 to identify survivors of first ACS (n = 12686), who were then followed up for recurrent events and all-cause mortality for three years. Finnish FINRISK risk factor surveys were used to determine the prevalence of risk factors (smoking, hyperlipidaemia, diabetes and blood pressure) in post-ACS patients (n = 199). Results Of the first ACS survivors, 48.4% had MACE within three years of their primary event, 17.0% were fatal. Diabetes (p = 4.4 × 10−7), heart failure (HF) during the first ACS attack hospitalization (p = 6.8 × 10−15), higher Charlson index (p = 1.56 × 10−19) and older age (p = .026) were associated with elevated risk for MACE in the three-year follow-up, and revascularization (p = .0036) was associated with reduced risk. Risk factor analyses showed that 23% of ACS survivors continued smoking and cholesterol levels were still high (>5mmol/l) in 24% although 86% of the patients were taking lipid lowering medication. Conclusion Diabetes, higher Charlson index and HF are the most important risk factors of MACE after the first ACS. Cardiovascular risk factor levels were still high among survivors of first ACS.

Prospective cohort study of nonspecific deprescribing in older medical inpatients being discharged to a nursing home.

Background:Older patients from nursing homes are commonly exposed to polypharmacy before a hospital admission. Deprescribing has been promoted as a solution to this problem, though systematic reviews have not found benefit. The aim of this study was to understand if in-hospital deprescribing of certain classes of medications is associated with certain benefits or risks.Methods:We conducted a prospective, multicentre, cohort study in 239 medical inpatients ⩾75 years (mean age 87.4 years) who were exposed to polypharmacy (⩾5 medications) prior to admission and discharged to a nursing home for permanent placement. Patients were categorised by whether deprescribing occurred, mortality and readmissions were assessed 30 and 90 days after hospital discharge. The EQ-5D-5 L health survey assessed changes in health-related quality of life (HRQOL) at 90 days, with comparison to EQ-5D-5 L results at day 30. Latent class analysis (LCA) was used to investigate associations between patterns of prescribed and deprescribed medications and mortality.Results:Patients for whom deprescribing occurred had a higher Charlson Index; there were no differences between the groups in principal diagnosis, total or Beers list number of medications on admission. The number of Beers list medications increased in both groups before discharge. Patients who had medications deprescribed had nonsignificantly greater odds of dying within 90 days [odds ration (OR) = 3.23 (95% confidence interval (CI): 0.68, 14.92; p = 0.136]. Deprescribing of certain classes was associated with higher 90-day mortality: antihypertensives (OR = 2.27, 95% CI: 1.004, 5; p = 0.049) and statins (OR = 5, 95% CI: 1.61, 14.28; p = 0.005). Readmissions and 1-year mortality rates were similar. There was no deterioration in HRQOL when medications were deprescribed. LCA showed that patients with the least medication changes had the lowest mortality.Conclusion:Deprescribing certain classes of medications during hospitalisation was associated with worse mortality, but not readmissions or overall HRQOL. Larger controlled deprescribing studies targeting specific medications are warranted to further investigate these findings.This study was registered with the Australian and New Zealand Clinical Trials Registry, ACTRN1 2616001336471.Plain language summaryBackground: When an older person living in a nursing home is admitted to hospital, does stopping long-term medications help them?Many older people from nursing homes take a large number of medications each day to treat symptoms and prevent adverse events. “Polypharmacy” is a term used to describe taking multiple long-term medications, and it is associated with many negative outcomes such as increased number of falls, cognitive decline, hospital readmission, even death. Deprescribing of nonessential medications – whether stopping or reducing the dose – is promoted as good hospital practice and is assumed to help older frail people live longer and feel better. However, we often don’t fully understand what is and is not essential.We wanted to better understand the effect of deprescribing long-term medications for older frail patients during an unplanned hospital admission as they were going to a nursing home to live.Methods: While admitted to hospital, medications are often reviewed by a clinical pharmacist and specialist physician. Sometimes medications are ceased; sometimes they are not. This gave us the opportunity to study two groups of older frail people from nursing homes: those who had regular, long-term medications ceased or reduced and those who did not. We wanted to see if one group did better. For example, did they feel worse if we stopped certain medications? Did they suffer other bad events compared with those patients for whom no medications were ceased? Were they readmitted to hospital earlier or more often?Results and conclusion: Despite the assumption that stopping medications for this type of patient is good practice, we found no benefit. We were also surprised to find stopping or reducing certain drug classes (e.g. antihypertensives and cholesterol-lowering drugs) was associated with greater mortality. Larger, randomised studies will better answer these important questions.

Causes of resistant pleural effusions and efficiency of chemical pleurodesis in these patients

To study the causes of resistant pleural effusions and efficiency of chemical pleurodesis with Betadin, Iodopyrone and concentrated glucose solution in these patients. Resistant pleuritis with daily exudation over 300 ml lasting ≥6 days occurred in 206 (48%) out of 424 cases of pleural effusions. Twenty-seven patients underwent chemical pleurodesis with Betadine, 15 patients - mixture of Iodopyrone with concentrated glucose solution. Solutions were injected via pleural drainage. In multivariate analysis, the risk factors of complicated pleuritis were air leakage, prolonged drainage period, age over 60 years, fluid output volume during thoracoscopy and higher Charlson index. Pleurodesis with a mixture of Betadine 10% 10 ml and glucose 40% 40 ml suppressed exudation in 92.6% of cases. Pleurodesis with a mixture of Iodopyron and glucose solution in the same quantities was effective in 93.4% of cases. If exudation continued, pleurodesis was repeated after 3 days. VAS score of pain syndrome following Iodopyrone injection was 3.0±1.8, in case of Betadine - 3.4±0.3. No significant hemodynamic changes were noted. In case of malignant pleural effusions and low functional parameters after fluid evacuation, favorable effect was obtained after pleurodesis with a mixture of povidone-iodine with glucose through the same catheter and subsequent removal of drainage tube. Resistant pleural effusions with daily exudation over 300 ml for more than 6 days are characterized by advanced risk of infectious and inflammatory complications due to air leakage and duration of drainage. Pleurodesis with mixtures of Betadine or iodopyrone and 40% glucose solution is effective for resistant pleural effusions.

Clinical Features of Cases with Anaerobic Infection, Distribution of Anaerobic Bacteria and Fatality in Anaerobic Bacteremia

Introduction: This study aimed to determine the distribution of anaerobic bacteria species, which are the causative agents of infection, in order to investigate the epidemiological and clinical characteristics of the cases and evaluate fatality in cases with an aerobic bacteremia. Materials and Methods: One hundred and twenty-five cases who were determined with 148 isolates of anaerobic bacteria were included into this study at Ankara Numune Training and Research Hospital Medical Microbiology Laboratory between January 2014-February 2018. The specimens requested to undergo anaerobic evaluation and transported to the laboratory under anaerobic suitable conditions were prepared with Gram staining and inoculated in the Schaedler agar. After appropriate incubation, the identification of isolated anaerobic bacteria at the level of species was performed by using matrix-assisted laser desorption time-of-flight (MALDI-TOF MS). Results: Of the 125 cases who had an anaerobic infection, 60% were males, and mean age was 52.69 ± 18.5 years. Intra-abdominal and skin and soft tissue infections were the most common source of infection. One hundred and twenty-eight clinical specimens (78 abscesses, 50 blood cultures) which were sent from cases were identified with 148 anaerobic bacteria species. We detected the most common isolated species as Bacteriodes spp., Actinomyces spp. and Clostridium spp., respectively. The most common anaerobic bacteria species isolated from blood cultures of 50 cases with anaerobic bacteremia were Bacteroides spp., Clostridium spp., and intra-abdominal infection was the most common source for anaerobic bacteremia. Fusobacterium nucleatum (5/6; 83.3%) was the most frequent species in Fusobacterium bacteremia. F. nucleatum bacteremia was detected in an older population and was often associated with underlying malignancy. F. necrophorum bacteremia occurred in a younger population without underlying comorbidities and was diagnosed as Lemierre’s syndrome. Fatality rate was 51% in anaerobic bacteremia. Fatality was significantly higher in patients who were followed up in the intensive care unit and had high Charlson index (p&lt; 0.05). Conclusion: MALDI-TOF MS has become an important method for the identification of anaerobic bacteria with its reliable results in a very short time. The most common anaerobic microorganism was Bacteroides spp., and the two most frequent sources of infection were intraabdominal and skin and soft tissue infections. We observed that most of the cases with F. nucleatum bacteremia had malignancy and an older population. The case with F. necrophorum bacteremia was young and had no underlying comorbidities. In this study, fatality rate (51%) was detected high in anaerobic bacteremia. Therefore, the routine use of anaerobic blood culture bottles is important for the identification and for the effective treatment of cases with anaerobic bacteremia.

Therapeutic Maintenance of Baricitinib and Tofacitinib in Real Life.

Background: Janus kinase inhibitors (JAKis) represent a new alternative to treat rheumatoid arthritis (RA). The objective of this study was to evaluate the effectiveness, tolerance profile, and maintenance of these treatments (tofacitinib and baricitinib) in real life. Methods: All patients in the rheumatology department of Amiens University Hospital treated by JAKis for RA were included from 1 October 2017 to 20 May 2020. Clinical and biological data were provided retrospectively in this observational and single-center study. We aimed to study the JAKi maintenance rate at 12 months and their clinical and biological safety profiles. Results: Fifty-five patients were included. Drug maintenance at 12 months was 67.6%. Factors associated with poorer maintenance were a higher Charlson comorbidity index (HR 1.311 (1.089–1.579); p = 0.0042), a higher age (HR 1.055 (1.015–1.096); p = 0.0067), and corticosteroids therapy at initiation (HR 2.722 (1.006–7.365); p = 0.0487). The clinical and biological safety profile was generally good. Conclusions: Our study found that a higher Charlson index, age, and corticosteroids appeared to be associated with the earlier discontinuation of treatment. JAKis had a response and tolerance profile in real life at least equivalent to that of biological disease-modifying antirheumatic drugs (bDMARDs).

Clinical Outcomes, Health Care Costs and Prognostic Factors for Total Knee Arthroplasty: A Multilevel Analysis of a National Cohort Study Using Administrative Claims Data.

Total knee arthroplasty (TKA) is one of the most frequent orthopaedic surgeries. The purpose of this study was to determine the 30-day postoperative mortality rate, total episode-of-care costs, and prognostic factors associated with these outcomes, for adult patients who underwent TKA in Colombia's contributory health care system. A retrospective cohort study of all adult patients enrolled in Colombia's contributory health system, who underwent TKA between January 1, 2012 and November 30, 2015 was performed. Thirty-day postoperative mortality rates, 30-day ICU admissions rates, 30-day hospital readmission rates, 1-year arthroplasty revision rates, and total episode-of-care costs were estimated. Multilevel, generalized linear models were generated, to determine the prognostic factors associated with outcomes presented. A total of 12,453 patients were included. The 30-day mortality rate was 0.13 per 100 surgeries and the ICU admissions rate at 30 days postoperative was 4.44 per 100 surgeries. The 30-day hospital readmission rate was 4.28 per 100 surgeries and the 1-year arthroplasty revision rate was 1.22 per 100 surgeries. The prognostic factors associated with mortality were age, Charlson Index, and type of insurer. The prognostic factors associated with hospital readmission were age category, Charlson Index, and geographic region; younger age and higher Charlson Index were found to be associated with a higher 1-year arthroplasty revision rate. The median of total episode-of-care costs was USD$ 6,190.07 (interquartile range: 2,299-7,282). The multivariate model found that age, the Charlson Index, the Atlantic region, and type of insurer were associated with the costs incurred by the health system. For patients undergoing TKA in Colombia, age, the Charlson Index, insurers, and geographic region are associated with mortality, ICU admissions, 30-day hospital readmissions, 1-year arthroplasty revisions, and total costs incurred by the health system.

COVID-19 in solid organ transplant recipients: No difference in survival compared to general population.

Coronavirus disease 2019 (COVID‐19) may be associated with worse outcome in solid organ transplant (SOT) recipients. We performed a prospective cohort study of hospitalized patients with confirmed diagnosis of COVID‐19, from March 15 to April 30, 2020, at two tertiary hospitals in Emilia‐Romagna Region. SOT recipients were compared with non‐SOT patients. Primary endpoint was all‐cause 30‐day mortality. Relationship between SOT status and mortality was investigated by univariable and multivariable Cox regression analysis. Patients were assessed from COVID‐19 diagnosis to death or 30‐day whichever occurred first. Study cohort consisted of 885 patients, of them 24 SOT recipients (n = 22, kidney, n = 2 liver). SOT recipients were younger, had lower BMI, but higher Charlson Index. At admission they presented less frequently with fever and respiratory failure. No difference in 30‐day mortality between the two groups (19% vs 22.1%) was found; however, there was a trend toward higher rate of respiratory failure (50% vs 33.1%, P = .07) in SOT recipients. Superinfections were more represented in SOT recipients, (50% vs 15.5%, P < .001). At multivariate analysis adjusted for main covariates, there was no association between SOT and 30‐day mortality HR 1.15 (95% CI 0.39‐3.35) P = .79. Our data suggest that mortality among COVID‐19 SOT recipients is similar to general population.

P1507COMPETING RISKS MODELING IN PERITONEAL DIALYSIS: THE URGE FOR A CHANGE IN SURVIVAL ANALYSIS METHODOLOGY

Abstract Background and Aims Survival analysis is a cornerstone in medical research. For this purpose Kaplan-Meier is the most widely used statistical test, but the presence of competing risks violates the fundamental assumption that the censoring mechanism is independent of survival time. This leads to overestimation of the cumulative probability of cause-specific failure. Cumulative incidence estimate and competing risks analysis are preferred. The purpose of this study was to compare different survival analysis methods: Kaplan-Meier and cumulative incidence function estimates in a cohort of Peritoneal Dialysis (PD) patients. Method The survival of 115 incident patients on PD in a university hospital was evaluated after establishing 2 cohorts: patients starting renal replacement therapy with PD (PD first; n=85) and patients switching to PD on the first 6 months of dialysis (PD transfer; n=30). Kaplan-Meier, cumulative incidence function, cause-specific and subdistribution hazards were performed. The event of interest was death and the competing risk events were transfer to hemodialysis and renal transplantation. Results Besides higher residual renal function (RRF) and kt/V in the PD first group, there were no other significant differences between groups. There were 22 deaths. PD first group had a better survival with both Kaplan-Meier (log-rank test, p=0.013) and cumulative incidence function (p=0.021) approaches. The Cox regression model showed, as protecting variables, higher albumin (HR=0.174; CI95% 0.054-0.562), higher RRF (HR=0.785; CI95% 0.666-0.925) and PD first (HR=0.350; CI95% 0.132-0.927). Higher Charlson Index predicted worse outcome (HR=1.459; CI95% 1.159-1.835). PD as first dialysis therapy was associated with 65.0 % lower risk of death comparing with PD transfer. The subdistribution multivariable model found higher Charlson Index (HR=1.389; CI95% 1.118-1.725) and lower RRF (HR=0.798; CI95% 0.680-0.936) were statistically associated with death, but not PD transfer or albumin. This result differs from the obtained using the cause-specific hazard model. Analyzing the competing events, patients submitted to renal transplantation had a lower Charlson Index. Conclusion The probability of death was overestimated by the Kaplan-Meier method. The bias of Kaplan-Meier is especially great when the hazard of the competing risks is large. This study consisted on a statistical critical analysis of a real medical example, broader clinical conclusions related with “PD first initiative” should be cautious in this context. It is primordial to recognize the presence of competing risks in studies with multiple outcomes, as in Peritoneal Dialysis studies, to estimate cumulative incidence and yield more accurate results. This study shows how different conclusions are attained with different statistical methodology and its relevance in clinical context.

Complex relationship between low albumin level and poor outcome after lower extremity procedures for peripheral artery disease

ObjectiveA low albumin level has been associated with poor outcome, including death, in surgical patients. The mechanistic relationship, however, is more complex than simply nutritional. As studies are scant in the vascular population, we sought to examine the association of low albumin level with outcomes in patients undergoing open and endovascular lower extremity procedures for peripheral artery disease. MethodsPatients with peripheral artery disease undergoing lower extremity procedures (2008-2015) were selected from Cerner Health Facts database (Cerner Corporation, Kansas City, Mo) using International Classification of Diseases, Ninth Revision diagnosis and procedure codes. Age, sex, disease severity, and other comorbidities were captured. Outcomes were identified using codes and encounter data. A χ2analysis and multivariable logistic regression were performed. ResultsThere were 6170 patients evaluated; 4562 (74%) underwent endovascular procedures and 1608 (26%) underwent open surgery. Low albumin level (<3.5 g/dL) was associated with age ≥80 years (23.1% vs 16.3% normal; P < .0001), black race (21% vs 11.6% normal; P < .0001), tissue loss (38% vs 16.4% normal; P < .0001), and higher Charlson index (mean, 3.1 vs 2.2 in the normal group; P < .0001). Low albumin level was also associated with longer length of stay (4.9 vs 2.2 days normal; P < .0001), higher in-hospital mortality (1.9% vs 0.3% normal; P < .0001), and higher 30-day readmission (15% vs 12.7% normal; P = .02). Multivariable analysis demonstrated that low albumin level was strongly associated with in-hospital death (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.00-13.70), infection (OR, 2.51; 95% CI, 1.96-3.22), renal failure (OR, 2.61; 95% CI, 1.79-3.79), and cardiac complications (OR, 2.59; 95% CI, 1.69-3.96). After multivariable adjustment, there was no association between albumin level and 30-day readmission. ConclusionsLow preoperative albumin levels are associated with in-hospital death, prolonged length of stay, and severe morbidity after open and endovascular lower extremity procedures. As the majority of lower extremity procedures are elective, serious consideration should be given to deferring elective procedures until albumin levels have been optimized. Because of the pleiotropic effects of albumin, including antiplatelet and inflammatory function, study of this complex relationship may offer insights into how best to integrate this novel biomarker into vascular surgery decision-making.

Trends in Hospitalizations for Clostridioides difficile Infection in End-Stage Liver Disease, 2005–2014

Data on the current estimates of the disease burden of Clostridioides difficile (C. difficile) infection in the setting of end-stage liver disease (ESLD) are emerging. We examined the recent trends and predictors of hospitalizations and in-hospital mortality from C. difficile infection among hospitalizations with ESLD in the USA. We performed a retrospective analysis using the National Inpatient Sample, 2005-2014. We defined ESLD and C. difficile infection using the International Classification of Diseases, Ninth Revision, Clinical Modification. Multivariable logistic regression was used to determine the risk factors that impacted hospitalization and mortality. The prevalence of coding for C. difficile infection in decompensated cirrhosis increased from 1.3% in 2005 to 2.7% in 2014, with an annual rate of 7.8%. In hospitalizations with hepatocellular carcinoma, C. difficile infection increased steadily from 1.0 to 1.7% with an annual incremental rate of 6.4%. Among hospitalizations with ESLD, each passing 2-year period, increasing age, female, higher Charlson index, accompanying infection, hepatorenal syndrome, and ascites were associated with C. difficile infection. Although C. difficile infection was an independent predictor of in-hospital mortality during hospitalization with decompensated cirrhosis (odds ratio 1.53, 95% confidence interval 1.44-1.63), the proportion of in-hospital mortality during hospitalization with C. difficile infection and decompensated cirrhosis decreased from 15.4% in 2005 to 11.1% in 2014, with an annual rate of - 3.1% (95% CI - 5.7% to - 0.3%). While the prevalence of C. difficile infection in hospitalized patients with ESLD increased approximately twofold, the in-hospital mortality decreased significantly during the past decade.

Influence of Pneumonia on the Survival of Patients with COPD

Background: Pneumonia is a frequent infection. Chronic obstructive pulmonary disease (COPD) can present with comorbidities, including pneumonia. It is known that COPD worsens the evolution of pneumonia, but few studies describe the impact of pneumonia on COPD evolution. This study analyzes the influence of pneumonia on the survival of COPD patients. Methods: Observational study of a cohort of 273 patients with COPD who attended spirometry in 2011, with a prospective follow-up of six years. Patients were divided into two groups according to their acquisition of pneumonia during follow-up. The difference in survival between the two groups was analyzed. Results: Survival was lower in the group with pneumonia compared with that without pneumonia (p = 0.000), both globally and after stratification by COPD phenotype. Pneumonia (Hazard Ratio -HR- 2.65; 95% Confidence Interval -CI- 1.57–4.48), advanced age (HR 1.08; 95% CI 1.03–1.09), and high Charlson index (HR 1.31; 95% CI 1.17–1.47) were identified as risk factors independently associated with mortality, while a high body mass index (HR 0.92; 95% CI 0.87–0.96) was identified as a protective factor. Conclusions: Pneumonia is associated with worse prognosis in COPD patients. It is important to take into account this comorbidity for a comprehensive care of these patients.

Resuming peritoneal dialysis after catheter removal due to complicated peritonitis.

Causes of non-resuming peritoneal dialysis (PD) after complicated peritonitis requiring peritoneal catheter (PC) removal remain poorly studied. We reviewed all peritonitis episodes in our center between 1997 and 2017. Patients who restarted PD after PC removal (Group 1) were compared to those who did not (Group 2), identifying the causes. Of 284 peritonitis episodes, PC was removed in 48 patients (16.9%). In 18 (37.5%) patients PC was reinserted, and PD successfully resumed in all, with a median duration of PD afterwards of 14.1months. In other 30 (62.5%) reinsertion of PC was not attempted. Causes of non-reinsertion were: transfer to hemodialysis 76.6% (n = 23), death 16.7% (n = 5) and transplantation 6.7% (n = 2). Hemodialysis switch was due to non-medical reasons in 47.8% (n = 11) including fear of peritonitis, family decision and social dependence. Group 1 was younger (p = 0.041), with lower Charlson index (p = 0.045) and higher men proportion (p = 0.049). Group 1 had a better patient survival than group 2 (survival at 24months: 67% and 53%, respectively; log-rank test p: 0.01). There were no differences in survival between groups when adjusted for significant basal characteristics. Resuming PD after severe peritonitis requiring PC removal is feasible but a high proportion of patients do not restart PD for non-medical reasons, usually older patients with higher Charlson index. A properly structured interview would be a useful tool that could improve return to technique in these patients.

Colonic stent vs surgical resection of the primary tumor. Effect on survival from stage-IV obstructive colorectal cancer.

the impact of surgical primary tumor resection on survival of obstructive metastatic colorectal cancer remains controversial. The primary goal of this study was to analyze survival in patients with obstructive metastatic colorectal cancer after treatment with either resection surgery or a colonic stent. a prospective study was performed of all patients with stage-IV colorectal cancer and obstructive manifestations, diagnosed from 2005 to 2012 and managed with either resection surgery or a colonic stent. Cases with a perforation, abscess, right colon or distal rectal malignancy, multiple colorectal cancer or derivative surgery were excluded. a total of 95 patients were included, 49 were managed with resection surgery and 46 with a colonic stent. The colonic stent group had a higher Charlson index (9.5 ± 2.1 vs 8.6 ± 1.5, p = 0.01), a shorter time to oral intake (0.9 ± 1.1 vs 16.4 ± 53.5 days, p = 0.05), a shorter hospital stay (4 ± 4.8 vs 16.7 ± 15.5 days, p = 0.0001), less need for stomata (11.1 % vs 32.7 %, p = 0.01), fewer early complications (4.3 % vs 46.9 %, p = 0.0001) and more late complications (33.3 % vs 6.4 %, p = 0.001). Undergoing chemotherapy (p = 0.008) was the only independent factor related to increased survival. In the subgroup of patients managed with chemotherapy, surgical primary tumor resection was an independent factor associated with increased survival. both treatments are effective for resolving obstructive manifestations in patients diagnosed with stage-IV obstructive colorectal cancer. Resection surgery has no positive impact on survival and thus cannot be recommended as a therapy of choice.

Home parenteral nutrition and the older adult: Experience from a national intestinal failure unit

The population in developed countries is getting older and with advancing age comes increasing co-morbidity and demand on health care services. The use of home parenteral nutrition (HPN) is also increasing in the UK and elsewhere. Age and co-morbidity need to be taken into consideration when HPN is contemplated because of the significant associated economic burden and clinical risk. However, there are minimal data on HPN outcomes specific to the elderly. We performed an observational study of a prospectively maintained database of patients dependent on HPN managed at a national U.K. referral centre. Data were collected on the 31st March 2018. Charlson index was used to assess co-morbidity. Data included demographics, HPN requirements, underlying disease aetiology, mechanism of intestinal failure, and whether the patient, carer or home care nurses administered the PN. The main outcome was the occurrence of at least one catheter-related blood stream infection (CRBSI) during HPN, with putative predictors of CRBSI assessed by uni- and multi-variable logistic regression. Two hundred and seventy-seven patients were included in this study, 62% were female and the overall mean age of the entire cohort was 58 years (range 20-93). The mean duration of HPN was 1778 days (range 45-12,832). One hundred patients were aged 65 years or older. Patients aged 65 years or older had a higher Charlson index (1.8 vs 1.1, p=<0.0001), were more likely to require a home care nurse to administer PN (p=0.01), and had the lowest risk of CRBSI (25% vs 39%; p=0.01). Home care nurse administration was associated with the lowest risk of CRBSI, followed by carer and self-administration (P=0.001). In multivariable analysis, duration of HPN and CVC care provider were the only independent predictors of CRBSI occurrence. There was no significant difference in unplanned intestinal failure-related hospital admissions between those under or above 65 years of age (p=0.08). HPN can be safely used in patients over the age of 65, even with increased co-morbidity. In this large cohort study, increasing age was found to be protective against CRBSI. CVC care provider was an independent predictor of CRBSI, while age and co-morbidity were not, suggesting that the use of home care nurses for PN administration is the principal reason for the low CRBSI rate in the elderly. Hence, older age should not be seen as a contra-indication for HPN, but increased healthcare resource may be required as those aged over 65 are more likely to require nursing assistance for CVC care.

Altered seric levels of albumin, sodium and parathyroid hormone may predict early mortality following hip fracture surgery in elderly.

To analyse a wide set of routine laboratory parameters at admission to predict mortality within 30 post-operative days in elderly patients with hip fracture, as well as calculate the critical values of those biomarkers. Data of 994 patients older than 65years with hip fracture were analysed of which 89 (8.2%) died within 30 post-operative days. Variables described in the literature with potential influence on early mortality were collected, including demographics, fracture type, American Society of Anesthesiologists score, Charlson's comorbidity index and pre-operative Hodkinson's mental test and the Katz index for activities of daily living. In addition, an exhaustive collection of biomarkers from routine blood testing at admission was performed. Critical levels of biomarkers were calculated by the method of area under ROC curve. At admission, early mortality group had significantly higher Charlson's index (p = 0.001) and lower the Katz index (p = 0.001). The surgical delay also was significantly longer in that group (p = 0.001). In univariate analyses, serum concentration at admission of total protein (p = 0.004), albumin (p = 0.001), sodium (p = 0.001), and parathyroid hormone (PTH) (p = 0.001) were significantly different between both groups. In multivariate analysis, serum albumin < 2.9g/dL (p = 0.013), sodium < 127mEq/L (p = 0.035) and PTH > 65pg/mL (p = 0.005) were predictors of early mortality. The three biomarkers together accounted for 67% of the variability in early mortality. The association of altered levels at admission of serum concentration of albumin, sodium and PTH was predictor of early mortality following hip fracture surgery in elderly patients.

Estudio ERCA. Características basales, evaluación de la aplicación de la información estructurada para la elección de tratamiento renal sustitutivo y evolución a un año de los pacientes incidentes en la consulta ERCA

Background and objectivesTo analyze evolution Renal Chronic Failure stage 4-5 (ACRF) patients and influence information they receive (educational process, EP) in modality Renal Replacement Therapy (RRT) or conservative treatment (CT) in multidisciplinar ACRF Office. Material and methodsProspective, multicenter study (3 centers). Inclusion: from June-01-2014 to October-01-2015; observation: 12 months or until start RRT or death if they occur before 12 months; ends October-01-2016. Results336 patients were included (60% males), median and intercuartile rank 71.5 (17), 55% ≥ 70 years; Follow up initiation eGFR CKD-EPI: 21 (9) ml / min / 1.73m2; Charlson Index (ChI) with / without age 8 (3) / 4 (2); Diabetic patients: 52,4%. The EP was carried out in 168, eGFR 15 (10) ml / min / 1.73m2. The initial treatment election: 26% peritoneal dialysis (PD), 45% hemodyalisis (HD), 26% CT, kidney trasplant 3%; 60 patients started RRT: 3.3% kidney traspant; 30% PD, 66% HD; 104 admissions in 73 patients, the most frequent cause: cardiovascular disease (42%). Deceased: 23 patients (6.8%). Age was higher (78.4 (6) vs. 67.8 (13.4), P<.001), higher ChI 9.8 (2.1) vs. 7.4 (2.5), P<.001). All deceased who received EP had chosen CT; 61% of deceased had at least one hospital admission vs. 39% alive (P<0.001). Cox regression: age and Charlson index were the predictive mortality variables. ConclusionsThe population of ACRF patients is elder, comorbid, with high hospitalizations rate. The PD election is higher than usual. The EP has been very useful tool and has favored the PD choice.

Glycaemic control after treatment intensification in patients with type 2 diabetes uncontrolled on two or more non-insulin antidiabetic drugs in a real-world setting.

To assess glycaemic control after treatment intensification in patients with type 2 diabetes uncontrolled on ≥2 non-insulin antidiabetic drugs (NIADS). A retrospective cohort study, using electronic health records from the SIDIAP database (2010-2014), was conducted. Intensification was defined as the prescription of any new antidiabetic drug in patients treated with ≥2 NIADS and HbA1c >7%. The primary outcome was the absolute change in HbA1c 6-12 months after any intensification. Secondary analyses included the percentage of patients reaching HbA1c <7%, HbA1c <8%, and a reduction of HbA1c >1% after the first intensification. There were 21 241 intensifications in 15 205 patients with a mean (SD) HbA1c of 9.02% (±1.35). Insulin and dipeptidyl peptidase-4 inhibitors (DPP4i) were the most frequently added therapies. The mean baseline-adjusted HbA1c reduction was 0.78% (95% CI, -0.80 to -0.76), varying from -0.69% with DPP4i to -0.85% with glucagon-like peptide-1 receptor agonists while the addition of insulin was associated with a reduction >1%. After the first intensification, 48.9% of patients achieved HbA1c <8%, 16.2% HbA1c <7%, and 43.1% a reduction >1%. High previous HbA1c was positively associated with the reduction of HbA1c >1% [odds ratio (OR) 2.13 (95% CI: 2.05-2.21)], but inversely associated with the attainment of HbA1c <7% [OR 0.64 (0.61-0.67)] or < 8% [OR 0.63 (0.60-0.65)]. Older age, male gender, higher Charlson index, and short diabetes duration were associated with achievement of HbA1c <7%. Despite intensification, most patients failed the glycaemic goal of HbA1c <7%. The reduction depended mainly on preintensification HbA1c values, with small differences between drugs.

Geriatric trauma

Background: Geriatric trauma demands attention in aging societies. The trauma hospitalization rate gradually increases in elderly populations because they are more vulnerable to accidental injuries. High trauma admission rates among elderly groups led to further research about injury patterns and outcomes. We hope to understand more about the demographic patterns and mortality rate of geriatric trauma. Methods: Information about all injured in-hospital patients ≥64 years was retrieved from a claims dataset from 2007 to 2008 from the Bureau of National Health Insurance in Taiwan. Statistical analyses were conducted on the population-based dataset to discover the incidence, mortality rate, percentage of chronic illness, and associations among variables such as age group, gender, injury mechanism, injury severity, and mortality. Results: A total of 134,024 patients (28.2% of total inpatients' admissions) ≥64 years were admitted in 2007 and 2008; 45.0% were male patients, and 43.9% were rural residents. These resulted in 4120 deaths. Nearly 40.0% of patients had at least one chronic illness. Diabetes mellitus was the most common comorbidity (20.2%). Injury was most commonly caused by falls on the same level, followed by motorcycle accidents. A higher mortality rate was observed in the subgroup with higher injury severity scores. Logistic regression showed that the mortality rate was significantly higher in subgroups comprising patients aged 75–84 and >84 years, with higher Charlson index, and with mechanisms such as pedestrians hit by vehicles or falls from height. Conclusion: High trauma hospitalization rates among elderly people can be reduced. Choosing a target population for injury prevention policy is required to reduce the geriatric trauma hospitalization rate. A regionalized trauma system providing the elderly population with optimal trauma care is mandatory.
