RESUMO

PURPOSE: To analyze the 10-year biochemical relapse-free survival (BRFS), locoregional relapse-free survival (LRFS), metastasis-free survival (MFS), and overall survival (OS) in patients diagnosed with localized prostate adenocarcinoma treated with radiotherapy (RT) ± androgen deprivation therapy (ADT), according to the risk groups based on multiparametric magnetic resonance imaging (mpMRI) instead of digital rectal exam (DRE). METHODS: We retrospectively evaluated 140 consecutive patients diagnosed with localized prostate adenocarcinoma, stratified into different risk groups-low (LR), intermediate (IR), and high (HR) by mpMRI results. RESULTS: After a median follow-up of 104 months, in LR group (n = 15), 10-year BRFS was 86.7%, 10-year LRFS was 86.7%, 10-year MFS was 93.3%, and 10-year OS was 100%. In IR group (n = 80), 10-year BRFS was 80.5%, 10-year LRFS was 86.1%, 10-year MFS was 92.6%, and 10-year OS was 76%. In HR group (n = 45), 10-year BRFS was 72.8%, 10-year LRFS was 78.7%, 10-year MFS was 82.1%, and 10-year OS was 77% (2 deaths from prostate cancer). According to mpMRI results, 36 (25.7%) patients change the risk group and 125 (89.28%) patients change the TNM stage. There was a trend for higher metastatic relapse in patients who switched from IR to HR (due to mpMRI) versus the patients who remained in the IR (20%, vs. 1.81% p = 0.059). Multivariate analysis showed that locoregional relapse was strongly associated with distant relapse (OR = 9.28; 95%CI: 2.60-33.31). There were no cases of acute grade 3 toxicity. Late grade 3 genitourinary, gastrointestinal, and sexual toxicity were 2.8%, 0.7%, and 1.2%, respectively. CONCLUSION: This is the first study with a 10-year median follow-up of patients diagnosed with localized prostate cancer treated with radiotherapy according to the risk groups established by mpMRI. Our findings show that mpMRI is a key tool to diagnose and establish risk groups in these patients, to optimize their treatment.

RESUMO

OBJECTIVES: to determine the safety and effect of intravenous iron sucrose on functional outcomes, delirium, nosocomial infections and transfusion requirements in older patients with hip fracture. DESIGN: single-centre randomised, double-blind, placebo-controlled clinical trial. SETTING AND PARTICIPANTS: orthogeriatric share care service at an academic tertiary care hospital. A total of 253 patients were recruited: 126 patients were assigned to intravenous iron and 127 to placebo. METHODS: on days 1, 3 and 5 after admission, the iron group received 200 mg Venofer® (iron sucrose) in 100 ml saline and the placebo group 100 ml saline. The primary outcome was absolute functional gain, considered as Barthel index (BI) at discharge minus BI on admission. Secondary outcomes included incidence of postoperative delirium according to the confusion assessment method, proportion of patients recovering prior functional status at 3 months, postoperative transfusion requirements, haemoglobin at 3 months, incidence of nosocomial infections and safety. RESULTS: the median participant age was 87 (interquartile range, 82.5-91.5) years. Most patients were female (72.7%), and the median previous BI was 81(59-95). No significant effect of intravenous iron was observed for the primary outcome: the median AFG score was 17.1 points (4.8-23.3) in the intravenous iron group and 16 points (6-26) in the placebo group (P = 0.369). No significant treatment effects were observed for other functional outcomes or secondary end points. CONCLUSION: while we found no impact of intravenous iron sucrose on functional recovery, incidence of postoperative delirium, transfusion requirements, haemoglobin at 3 months, mortality and nosocomial infections rates in older patients with hip fracture, we did find that the intervention was safe.

RESUMO

AIM: To evaluate whether positron-emission tomography/computed tomography with 68Ga-PSMA (68Ga-PSMA PET/CT) influences the therapeutic management of patients with primary or recurrent prostate cancer (PCa). BACKGROUND: Although 68Ga-PSMA PET/CT is one of the best options for staging or restaging patients with PCa, its availability is still very limited in Spain. The present study reports the results of the first group of patients in Spain who underwent 68Ga-PSMA PET/CT imaging. MATERIALS AND METHODS: All patients (n = 27) with a histological diagnosis of PCa who underwent 68Ga-PSMA PET/CT prior to the definitive treatment decision at the only centre with this technology in Spain during 2017-2018 were included. Two nuclear medicine physicians and a radiologist reviewed the imaging studies. The clinical impact was assessed from a theoretical perspective, based on the treatment that would have been applied if no data from the 68Ga-PSMA PET/CT were available. RESULTS: Most patients (n = 26; 96%) had persistent disease or biochemical recurrence after radical prostatectomy, radiotherapy, or combined treatment. One patient underwent 68Ga-PSMA PET/CT imaging to stage high-risk PCa. Overall, 68Ga-PSMA PET/CT was positive in 19 patients (70.4%). In 68.75% of these patients, none of the other imaging tests-MRI, CT, or bone scans-performed prior to the 68Ga-PSMA PET/CT were able to detect the presence of cancerous lesions. Overall, the findings of the 68Ga-PSMA PET/CT led to a modification of the therapeutic approach in 62.96% of the patients in the study. CONCLUSIONS: 68Ga-PSMA PET/CT alters the therapeutic approach in a substantial proportion of patients with PCa.

RESUMO

AIM: To determine the patterns of antibiotic susceptibility of Escherichia coli strains isolated from adult patients with urinary tract infection (UTI), and to stratify the results by age and type of UTI to verify if there are statistically significant differences that can help physicians to prescribe better empirical antibiotherapy. DESIGN: Cross-sectional prospective study. LOCATION: Community of Getafe (Madrid). Primary care level. PARTICIPANTS: 100 E. coli strains, randomly chosen, isolated from the urine (104-105cfu/ml) of different patients from primary care centers in the Getafe area. MAIN MEASUREMENTS: The antibiotic susceptibility of the strains was evaluated and the results were stratified by age and type of UTI. The clinical and demographic data of the patients were analyzed, classifying each episode as complicated UTI or uncomplicated UTI. RESULTS: Strains isolated from patients with uncomplicated UTI showed significantly greater susceptibility than those of complicated UTI to amoxicillin (65.9% vs. 30.6%, p=0.001), amoxicillin/clavulanic acid (95.5% vs. 77.6%, p=0.013) and ciprofloxacin (81.8% vs. 63.3%, p=0.047). In complicated UTI, susceptibility to ciprofloxacin was significantly greater in the ≤65 years age group compared to the older age group (78.3% vs. 50%, respectively, p=0.041). In the rest of antibiotics, no statistically significant differences were obtained when comparing by age (≤65 years versus >65 years), both in uncomplicated and complicated UTI. CONCLUSIONS: Clinical and demographic data of patients with UTI are of great importance in the results of the antibiotic susceptibility in E. coli. Antibiograms stratified by patient characteristics may better facilitate empirical antibiotic selection for UTI in primary care.

RESUMO

AIM: To analyse the efficacy and toxicity of postprostatectomy SRT in patients with a BCR evaluated with mpMRI. BACKGROUND: Multiparametric magnetic resonance imaging (mpMRI) has the ability to detect the site of pelvic recurrence in patients with biochemical recurrence (BCR) after radical prostatectomy (RP). However, we do not know the oncological outcomes of mpMRI-guided savage radiotherapy (SRT). RESULTS: Local, lymph node, and pelvic bone recurrence was observed in 13, 4 and 2 patients, respectively. PSA levels were significantly lower in patients with negative mpMRI (0.4 ng/mL [0.4]) vs. positive mpMRI (2.2 ng/mL [4.1], p = 0.003). Median planning target volume doses in patients with visible vs. non-visible recurrences were 76 Gy vs. 70 Gy. Overall, mean follow-up was 41 months (6-81). Biochemical relapse-free survival (bRFS) at 3 years was 82.3% and 82.5%, respectively, for the negative and positive mpMRI groups (p = 0.800). Three-year rates of late grade ≥2 urinary and rectal toxicity were 14.8% and 1.9%, respectively; all but one patient recovered without sequelae. CONCLUSION: SRT to the macroscopic recurrence identified by mpMRI is a feasible and well-tolerated option. In this study, there were no differences in bRFS between MRI-positive and MRI-negative patients, indicating effective targeting of MRI-positive lesions.

RESUMO

BACKGROUND: Patient blood management (PBM) performs multidisciplinary strategies to optimize red blood cell (RBC) transfusion. Orthogeriatric share care models (surgeon and geriatrician manage the patient together from admission) have the goal of improving outcomes in hip fracture patients. MATERIAL AND METHODS: A prospective observational study was conducted. Patients aged ≥70 years undergoing hip fracture (HF) surgery were consecutively included. When admitted on the orthogeriatric service a PBM protocol was applied based on: perioperative antithrombotic management, intravenous iron sucrose administration and restrictive transfusion criteria. Risk factors, clinical and functional effects of transfusion and its requirements were assessed to audit our model. RESULTS: A total of 383 patients participated (women, 78.8%; median age, 86 (82-90) years). 210 patients (54.8%) were transfused. Age (OR = 1.055, 95% CI 1.017-1.094; p = 0.004) and Hemoglobin (Hb) level on admission (OR = 0.497, 95% CI 0.413-0.597; p < 0.001) were found to be significant risk factors for transfusion. Transfusion increased length of stay (b = 1.37, 95% CI 0.543-2.196; p = 0.001) but did not have an effect on other variables. DISCUSSION: The PBM program established within an orthogeriatric service showed positive outcomes in terms of clinical complications, mortality, delirium or functional recovery in transfused patients, whereas it did not impact on shorter length of stay. The risk of transfusion on admission was predicted with the lower Hb levels on admission, along with the age of the patients. New measurements as homogenous restrictive transfusion criteria, a single-unit RBC transfusion and the assessment of the intravenous iron efficacy are need to be applied as a result of the high transfusion requirements.

RESUMO

PURPOSE: We studied the impact of age on survival and functional recovery in brain-injured patients. METHODS: We performed an observational cohort study of all consecutive adult patients with brain injury admitted to ICU in 8 years. To estimate the optimal cut-off point of the age associated with unfavorable outcomes (mRS 3-6), receiver operating characteristic (ROC) curve analyses were used. Multivariate logistic regression analyses were performed to identify prognostic factors for unfavorable outcomes. RESULTS: We included 619 brain-injured patients. We identified 60 years as the cut-off point at which the probability of unfavorable outcomes increases. Patients ≥ 60 years had higher severity scores at ICU admission, longer duration of mechanical ventilation, longer ICU and hospital stays, and higher mortality. Factors identified as associated with unfavorable outcomes (mRS 3-6) were an advanced age (≥ 60 years) [Odds ratio (OR) 4.59, 95% confidence interval (CI) 2.73-7.74, p < 0.001], a low GCS score (≤ 8 points) [OR 3.72, 95% CI 1.95-7.08, p < 0.001], the development of intracranial hypertension [OR 5.52, 95% CI 2.70-11.28, p < 0.001], and intracerebral hemorrhage as the cause of neurologic disease [OR 3.87, 95% CI 2.34-6.42, p < 0.001]. CONCLUSION: Mortality and unfavorable functional outcomes in critically ill brain-injured patients were associated with older age (≥ 60 years), higher clinical severity (determined by a lower GCS score at admission and the development of intracranial hypertension), and an intracerebral hemorrhage as the cause of neurologic disease.

RESUMO

(1) Multiple in vitro studies reported insufficient accuracy of intraoral scanners (IOSs) for complete-arch multiple implant impression. The aim of the study is to analyze the precision of three IOSs, PIC dental (Pic dental, Iditec North West SL), TRIOS 3 (3Shape), and True Definition (Midmark Corporation) and the influence of several factors in the edentulous complete maxillary and mandibular arch. (2) A fully edentulous patient with eight implants in the maxillary and in the mandibular jaw was selected. Five impressions were taken per system and arch. A suprastructure was designed on each digital working cast. The precision was analyzed comparing each of the 28 distances and seven relative angulations of the abutments of all the designed suprastructures. The descriptive statistics, the Student's t-test, and the ANOVA test were used to analyze the data (α = 0.05). (3) Significant differences were observed when comparing the IOSs in some of the distances and angulations. (4) The increase in the distance between implants affected the precision of T and TD but not the PIC system. The type of arch did not affect the PIC precision, but the T and TD systems performed worse in the mandibular arch. The system with the best precision was the PIC, followed by TD, and then T.

RESUMO

Objective: Physical exercise is associated with several benefits in the treatment of cystic fibrosis (CF), associated with a reduction in patient mortality. The aim of this systematic review was to determine the effectiveness of exercise interventions on physical condition and lung function in children and adults with CF to establish the most appropriate type and dose of physical exercise used so far. Methods: The studies included were randomized controlled trials with physical exercise interventions performed with children or adults with CF, analyzing the effects on pulmonary function, cardiorespiratory capacity, and muscle strength. The variables analyzed in at least four studies in the same population (children or adults) with the same measuring test were included in the meta-analysis. Results:Pulmonary function: There were no changes in the forced expiratory volume 1 s, but mouth expiratory/inspiratory pressures were improved in some studies. Physical fitness: In children, the interventions did not manage to improve the VO2peak (SMD = 0.22; 95%CI: -0.25 to 0.68; p = 0.73) but improved muscle strength. In adults, physical exercise interventions based on high-intensity aerobic training showed positive results in the VO2peak, and in some muscle strength outcomes. Conclusions: Exercise interventions in children and adults with CF are effective in improving muscle strength, cardiovascular capacity, and respiratory muscle function. However, they do not achieve improvements in lung function. The most effective programs are those using strength training or cardiovascular high-intensity interval training, although to date there have been few such interventions.

RESUMO

PURPOSE: To analyze the feasibility, accuracy and the ability of different frailty instruments to predict adverse outcomes. METHODS: A prospective cohort study was conducted in patients ≥ 70 years admitted to the acute care setting (ACS). Feasibility and prevalence of frailty were assessed by FRAIL, Clinical Frailty Scale (CFS), hand grip strength (HGS) and the Spanish Frailty-VIG. Receiver operator characteristic (ROC) curves and area under the curve (AUC) were performed to identify frailty according to each instrument, setting VIG as the reference. For each instrument, multiple logistic regressions were used to examine the effect of frailty on primary outcome (i.e., three-month mortality) and secondary outcomes (i.e., in-hospital mortality, length of stay, institutionalization, functional decline and 30-day readmission). RESULTS: A total of 185 patients were included, with a median age of 89 years. The feasibility of the instruments was 100%, except for HGS (67%). The prevalence of frailty varied from 65.2% (FRAIL) to 86.7% (VIG). AUCs against VIG ranged from 0.69 (95% confidence interval [CI] 0.57-0.81: FRAIL) to 0.77 (95% CI 63.5-90.2: CFS). Frail patients defined by FRAIL were 2.7times more likely to have a prolonged length of stay than non-frail patients (95% CI 1.385-5.416). Three-month mortality occurred more among frail patients, either defined by FRAIL (OR 2.5; 95% CI 1.072-5.881) or CFS (OR 3.7; 95% CI 1.255-10.812), than in non-frail patients. CONCLUSION: The four instruments had high feasibility providing variable prevalence of frailty. FRAIL and CFS predicted well for three-month mortality, and FRAIL also for length of stay. However, none of the instruments predicted for the other secondary outcomes of the study.

RESUMO

OBJECTIVES: To describe the clinical characteristics, 30-day mortality, and associated factors of patients living in nursing homes (NH) with COVID-19, from March 20 to June 1, 2020. DESIGN: This is a retrospective study. A geriatric hospital-based team acted as a consultant and coordinated the care of older people living in NHs from the hospital. SETTING AND PARTICIPANTS: A total of 630 patients aged 70 and older with Coronavirus Disease 2019 COVID-19 living in 55 NHs. METHODS: A logistic regression was performed to analyze the factors associated with mortality. In addition, Kaplan-Meier curves were applied according to mortality and its associated factors using the log-rank Mantel-Cox test. RESULTS: The diagnosis of COVID-19 was mainly made by clinical compatibility (N = 430). Median age was 87 years, 64.6% were women and 45.9% were transferred to be cared for at the hospital. A total of 282 patients died (44.7%) within the 30 days of first attention by the team. A severe form of COVID-19 occurred in 473 patients, and the most frequent symptoms were dyspnea (n = 332) and altered level of consciousness (n = 301). According to multiple logistic regression, male sex (P = .019), the Clinical Frailty Score (CFS) ≥6 (P = .004), dementia (P = .012), dyspnea (P < .001), and having a severe form of COVID-19 (P = .001), were associated with mortality, whereas age and care setting were not. CONCLUSIONS AND IMPLICATIONS: Mortality of the residents living in NHs with COVID-19 was almost 45%. The altered level of consciousness as an atypical presentation of COVID-19 should be considered in this population. A severe form of the disease, present in more than three-quarters of patients, was associated with mortality, apart from the male sex, CFS ≥6, dementia, and dyspnea, whereas age and care setting were not. These findings may also help to recognize patients in which the Advance Care Planning process is especially urgent to assist in the decisions about their care.

RESUMO

AIM: We aimed to investigate the impact of delirium on short-term outcomes in hip fracture patients. Special attention was given to patients with delirium and dementia. METHODS: A prospective observational cohort study was carried out in hip fracture patients aged ≥70 years who were admitted to a hospital unit where a multicomponents approach to delirium is established for all patients. Our population was split into delirium (n = 212) and non-delirium cohort (n = 171) according to the Confusion Assessment Method. Patients with a previous diagnosis of dementia in an outpatient appointment were also assessed within the delirium cohort. The utility of the rehabilitation was measured with the Absolute Functional Gain index. RESULTS: A total of 383 patients were entered into the study. The median age was 86 years, and most patients were women (78.8%). Delirium patients were older, presented a lower previous Barthel Index (BI), had higher rates of dementia and came more frequently from nursing homes. Comparative analysis did not show differences in mortality, complications, length of stay or walking ability between the cohorts. However, lower BI on discharge, lower Absolute Functional Gain and the presence of nosocomial infections were found more frequently in the delirium cohort. In multivariate analysis, only the BI on discharge (P = 0.010) was lower in delirium patients. Within the delirium cohort, those suffering from dementia had worse BI on discharge (P = 0.017) and lower Absolute Functional Gain (P = 0.019). CONCLUSIONS: Delirium was not associated with mortality, walking ability, length of stay and clinical complications in hip fracture patients. BI on discharge was the only short-term outcome affected. In the delirium cohort, those suffering from dementia showed worse rehabilitation results. Geriatr Gerontol Int 2020; 20: 130-137.

RESUMO

INTRODUCTION: Graft is an alternative to native arteriovenous fistula to ensure permanent vascular access in hemodialysis patients. The most common complication is significant stenosis, which frequently causes thrombosis and graft loss. Periodic monitoring and surveillance with elective correction of stenotic lesions can prolong graft survival. OBJECTIVE: To describe the effect of early diagnosis of significant stenosis on the rate of thrombosis and graft patency. METHODS: Retrospective, observational study of a cohort of 86 prevalent patients undergoing hemodialysis with a graft as their vascular access. We applied a systematic follow-up protocol of 115 grafts based on various screening methods of monitoring (clinical monitoring, pre-pump arterial pressure, dynamic venous pressure, percentage of recirculation, and dose of dialysis) in conjunction with surveillance (normalized intra-access venous pressure and access flow). The annual rates of thrombosis, and primary, primary-assisted, and secondary patency were assessed. RESULTS: The incidence of significant stenosis and thrombosis was 57.4% (65/115) and 39.0% (45/115), respectively. Of all screening procedures, normalized intra-access venous pressure was the best predictor of significant stenosis (hazards ratio, 7.71; 95% confidence interval, 3.06-19.46). The annual rate of thrombosis fluctuated from 0 to 0.26 thromboses/patient/year, with an average rate of 0.14 thromboses/patient/year. Primary, primary-assisted, and secondary patency were 74%/79%/82%, 50%/60%/66%, and 23%/35%/37% at 1, 2, and 5 years, respectively. CONCLUSION: The implementation of a systematic graft follow-up protocol combined with monitoring and surveillance enabled early diagnosis and elective correction of significant stenosis, prolonged graft patency, and a low thrombosis rate.

RESUMO

INTRODUCTION: The incidence of clinical complications in hip fracture (HF) patients is high and variable due to their heterogeneous nature. The aim of the study was to assess the clinical complications and their associated factors in HF patients admitted to the Orthopaedic Geriatric Unit of a 283 bed University Hospital. An average of 200 HF patients is attended yearly. MATERIAL AND METHODS: A prospective, observational and analytical study was conducted on 383 consecutive patients admitted to the unit during the years 2013 and 2014. Clinical complications were defined according to recommendations supported by the AOTrauma Network (International Network of Traumatologists for the Study of Osteosynthesis). RESULTS: A total of 273 patients (71.28%) showed some clinical complication. The main ones were, delirium (55.4%), renal failure (15.4%), and cardiac complications (12.3%). An ASA III-IV score of OR = 1.962 (95% CI; 1.040-3.704, P=.038), lower Barthel index at discharge (b = -3.572, 95% CI -0.866 to -0.104, P=.01), the increase in pre-operative stay (OR = 1.165, 95% CI 1.050-1.294, P=.004) and an increased length of stay (b = 2.663, 95% CI 3.522-0.325; P<.001) were factors associated with clinical complications. CONCLUSIONS: Delirium, renal failure, and cardiac complications were the most frequent complications according the new recommendations. An ASA III-IV score, worse functional status at discharge, prolonged pre-operative period, and increased length of stay, were risk factors associated with clinical complications. Cardiac, pulmonary, and gastrointestinal complications were the main causes of mortality in the unit.

RESUMO

BACKGROUND: To evaluate and compare the utility of 18F-fluorocholine (18F-CH) PET/CT versus 3-Tesla multiparametric MRI (mpMRI) without endorectal coil to detect tumor recurrences in patients with biochemical relapse following radical prostatectomy (RP). Secondarily, to identify possible prognostic variables associated with mpMRI and 18F-CH PET/CT findings. METHODS: Retrospective study of 38 patients who developed biochemical recurrence after RP between the years 2011 and 2015 at our institution. PET/CT and mpMRI were both performed within 30 days of each other in all patients. The PET/CT was reviewed by a nuclear medicine specialist while the mpMRI was assessed by a radiologist, both of whom were blinded to outcomes. RESULTS: The median prostate-specific antigen (PSA) value pre-MRI/PET-CT was 0.9 ng/mL (interquartile range 0.4-2.2 ng/mL). There were no differences in the detection rate between 18F-CH PET/CT and mpMRI for local recurrence (LR), lymph node recurrence (LNR) and bone metastases (BM). Separately, mpMRI and 18F-CH PET/CT were positive for recurrence in 55.2% and 52.6% of cases, respectively, and in 65.7% of cases when findings from both modalities were considered together. The detection of LR was better with combined mpMRI and choline PET/CT versus choline PET/CT alone (34.2% vs 18.4%, p = 0.04). Salvage treatment was modified in 22 patients (57.8%) based on the imaging findings. PSA values on the day of biochemical failure were significantly associated with mpMRI positivity (adjusted odds ratio (OR): 30.9; 95% confidence interval (CI): 1.5-635.8). Gleason score > 7 was significantly associated with PET/CT positivity (OR: 13.9; 95% CI: 1.5-125.6). A significant association was found between PSA doubling time (PSADT) (OR: 1.3; 95% CI: 1.0-1.7), T stage (OR: 21.1; 95% CI: 1.6-272.1), and LR. CONCLUSIONS: Multiparametric MRI and 18F-CH PET/CT yield similar detection rates for LR, LNR and pelvic BM. The combination of both imaging techniques provides a better LR detection versus choline PET/CT alone. The initially planned salvage treatment was modified in 57.8% of patients due to imaging findings. In addition to PSA values, Gleason score, T stage, and PSADT may provide valuable data to identify those patients that are most likely to benefit from undergoing both imaging procedures.
