RESUMO
Background: The aim of the study was to analyze the impact of palliative radiotherapy on quality of life (QoL) in patients with symptomatic bone metastases. Materials and methods: We present the results from a prospective multicentric study including 128 patients who provided pre- and post-radiotherapy (one month after treatment) brief pain inventory (BPI) assessments. Worst pain was recorded using the BPI (range: 0-10). Pain response was described according to the International Bone Metastases Consensus on palliative radiation. Regarding QoL, for each pre- and post-radiation BPI-questionnaire, scores from the interference domains were summed and averaged to obtain an overall interference score. Results: There was a significant correlation between radiation treatment response and improvement in all functional interference domains except sleeping. Patients > 75 years old presented a significantly higher improvement in general activity, mood and relationships with others compared to patients ≤ 75 years old. Patients presenting a baseline pain score ≥ 8 showed a higher improvement in the general activity item (p = 0.049). There was no statistically significant association between pretreatment ECOG, chemotherapy, primary tumor location and radiation schedule with any of the functional interference items. Conclusions: Patients who report pain relief after palliative radiotherapy also present a better quality of life including physical and psychosocial aspects.
RESUMO
AIM: Escherichia coli (E coli) is a known cause of paediatric bacteraemia. The main objective was to characterise the emergency department (ED) presentations of paediatric E coli bacteraemia and secondarily to identify those related to greater severity. METHODS: This was a sub-study of a multicentre cross-sectional prospective registry including all with E coli bacteraemia episodes between 2011 and 2016. We used multiple correspondence and cluster analysis to identify different patterns. RESULTS: We included 291 patients and 43 met criteria for severe disease (14.3%, 95% confidence interval 11.2-19.3). We identified four types of paediatric E coli bacteraemia presentations. Two (178 patients, 61.2%) were related to well-appearing previously healthy infants with associated urinary tract infection (UTI). Well-appearing children older than 12 months old with underlying disease (n = 60, 20.6%) and non-well-appearing children of different ages (n = 53, 18.2%) corresponded to the other two types; these had associated UTI infrequently and higher severity rate (15% and 50.9%, respectively, higher when compared with the two previous types, P < .01), including the two patients who died. CONCLUSION: There were four different types of ED paediatric E coli bacteraemia presentations with different severity. Febrile young children with associated UTI showed the best outcome.

INTRODUCTION: since Lauren classified gastric cancer into intestinal-type adenocarcinoma and diffuse gastric carcinoma back in 1965, countless categorizations have been published that attempt to elucidate the clinicopathological and prognostic differences between histological subtypes. OBJECTIVE: a retrospective study was performed of gastric cancer cases managed in a third-level site over ten years in order to compare subtypes between the most widely used classifications (Lauren and World Health Organization [WHO]). METHODS: a comparative study of the most relevant clinicopathological characteristics and a multivariate survival analysis were performed. RESULTS: significant differences exist between histological subtypes in terms of age, gender, location, extension, stage and treatment received. A univariate overall survival analysis revealed better survival rates for intestinal-type adenocarcinoma as compared to diffuse carcinoma (hazard ratio [HR]: 1.405 [1.024-1.927]) according to the Lauren's classification. Furthermore, there was a better prognosis of mucinous carcinoma (HR: 0.378 [0.164-0.868]), though failing to prove a poorer prognosis of poorly cohesive (HR: 1.242 [0.878-1.757]) and signet cell (HR: 1.354 [0.792-2.314]) carcinomas, according to the WHO classification. In the multivariate overall survival analysis, the following poor prognosis factors were identified: male gender, local infiltration (T), nodal invasion (N) and received adjuvant therapy. CONCLUSION: although the various histological subtypes show significant clinicopathological differences, further studies are needed to compare them and clarify the prognostic relevance of each one.

OBJECTIVE: To identify risk factors associated with severe anaphylaxis in children. STUDY DESIGN: We carried out a multicenter prospective observational study including children less than 18 years old diagnosed with anaphylaxis in 7 Spanish pediatric emergency departments (EDs) between May 2016 and April 2018. Children were considered to have severe anaphylaxis if they met one or more of the following criteria: requirement for 2 or more doses of epinephrine, clinically important biphasic reaction, endotracheal intubation, intensive care unit admission, and/or death. RESULTS: We included 453 episodes of anaphylaxis. Of these, 61 were classified as severe anaphylaxis (13.5%, 95% CI [10.6-16.9]): 53 (11.7%) required more than 1 dose of epinephrine, and there were 14 (3.1%) cases of clinically important biphasic reactions, 2 (0.4%) intubations in the ED, and 6 (1.3%) admissions to the intensive care unit. No patients died. In the multivariable regression, we identified 5 independent risk factors for severe anaphylaxis: history of asthma (P = .002; OR 2.705, 95% CI [1.431-5.113]), onset of the symptoms less than 5 minutes after the allergen exposure (P = .002; OR 2.619, 95% CI [1.410-4.866]), non-well appearance (P = .005; OR 2.973, 95% CI [1.380-6.405]), tachycardia (P = .014; OR 2.339, 95% CI [1.191-4.959]), and hypotension (P = .036; OR 3.725, 95% CI [1.087-12.762]). CONCLUSIONS: Childhood anaphylaxis is usually well controlled in the ED. Children with a history of asthma, rapid onset of the symptoms, who are non-well appearing, or have tachycardia or hypotension upon arrival to the ED are more likely to have severe episodes.

BACKGROUND AND OBJECTIVE: Identifying international differences in the epidemiology of acute poisonings in children may help in improving prevention. We sought to evaluate the international epidemiological differences in acute poisonings in children presenting to emergency departments (EDs) from 8 different global regions. METHODS: This was an international multicenter cross-sectional prospective study including children younger than 18 years with acute poisonings presenting to 105 EDs in 20 countries was conducted. Data collection started at each ED between January and September 2013, and continued for 1 year. RESULTS: During the study period, we registered 363,245 pediatric ED presentations, of which 1727 were for poisoning (0.47%; 95% confidence interval, 0.45%-0.50%), with a significant variation in incidence between the regions. Full data were obtained for 1688 presentations. Most poisonings (1361 [80.6%]) occurred at home with either ingestion (1504 [89.0%]) or inhalation of the toxin (126 [7.6%]). Nonintentional exposures accounted for 1157 poisonings (68.5%; mainly in South America and Eastern Mediterranean region), with therapeutic drugs (494 [42.7%]), household products (310 [26.8%]), and pesticides (59 [5.1%]) being the most common toxins. Suicide attempts accounted for 233 exposures (13.8%; mainly in the Western Pacific region and North America), with therapeutic drugs (214 [91.8%], mainly psychotropics and acetaminophen) being the most common toxins. Significant differences between regions were found in both types of poisonings. Recreational poisonings were more common in Europe and Western Pacific region. No patient died. CONCLUSIONS: There are substantial epidemiological differences in acute poisonings among children in different countries and regions of the globe. International best practices need to be identified for prevention of acute poisonings in childhood.

RATIONALE: In chronic obstructive pulmonary disease (COPD), the benefits of pulmonary rehabilitation (PR) tend to wane over time. Whether maintenance techniques may help sustain the benefits achieved after completion of the initial PR program remains controversial. OBJECTIVES: To determine whether a long-term (3-yr) maintenance program after PR preserves the short-term effects on outcomes in patients with COPD. METHODS: This was a multicenter prospective randomized trial including 143 patients with moderate-severe COPD, with 3 years of PR maintenance following an 8-week outpatient PR program. Patients were randomized to maintenance intervention group (IG) and standard monitoring program or control group (CG). The effects on BODE index, 6-minute-walk test distance (6MWD), and health-related quality of life were compared at 12, 24, and 36 months. MEASUREMENTS AND MAIN RESULTS: A total of 138 (96.5%) completed the 8-week program. At this time, all outcomes (BODE, 6MWD, and health-related quality of life) showed clinically and statistically significant improvements (P ≤ 0.001). During the follow-up period, the magnitude of change in 6MWD differed between IG and CG (P = 0.042), with a slight initial increase in the IG during the first year and smaller decline afterward. The BODE index changes differed between baseline and measurements at Month 24 (P = 0.043). At 3 years, the adherence rate of IG patients was 66% and 17% for the CG group (P < 0.001). CONCLUSIONS: This study shows a 2-year beneficial effect of a program of rehabilitation maintenance on the BODE index and 6MWD when compared with a standard strategy. This effect vanishes after the second year of follow-up. Clinical trial registered with www.clinicaltrials.gov (NCT 01090999).

BACKGROUND: Assessment tools to classify and prioritize patients, such as systems of triage, and indicators of severity, such as clinical respiratory scores, are helpful in guiding the flow of asthmatic patients in the emergency department. OBJECTIVE: Our aim was to assess the performance of the Pediatric Assessment Triangle (PAT), triage level (TL), Pulmonary Score (PS), and initial O2 saturation (O2 sat), in predicting hospitalization in pediatric acute asthma exacerbations. STUDY DESIGN: Retrospective study evaluating PAT, TL, and PS at presentation, and initial O2 sat of asthmatic children in the pediatric emergency department (PED). The primary outcome measure was the rate of hospitalization. Secondary outcomes were length of stay (LOS) in the PED and admission to the pediatric intensive care unit (PICU). RESULTS: PAT, TL, PS, and initial O2 sat were recorded in 14,953 asthmatic children. Multivariate analysis yielded the following results: Abnormal PAT and more severe TLs (I-II) were independent risk factors for hospitalization (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.4-1.8; OR 3.4, 95% CI 2.6-4.3, respectively) and longer LOS (OR 1.5, 95% CI 1.3-1.7; OR 2.6, 95% CI 2-3.3, respectively). PS > 3 showed a strong association with hospitalization (OR 8.1, 95% CI 7-9.4), PICU admission (OR 9.6, 95% CI 3-30.9) and longer LOS (OR 6.2, 95% CI 5.6-6.9). O2 sat < 94% was an independent predictor of admission (OR 5.2, 95% CI 4.6-5.9), PICU admission (OR 4.6, 95% CI 4.5-4.6), and longer LOS (OR 4.6, 95% CI 4.1-5.2). CONCLUSIONS: PAT, TL, PS, and initial O2 sat are good predictors of hospitalization in pediatric acute asthma exacerbations.

OBJECTIVE: This study aimed to assess the association between pediatric assessment triangle (PAT) findings during triage and markers of severity in a pediatric emergency department (PED). METHODS: During the study period, patients arriving to the PED were classified by trained nurses with the Pediatric Canadian Triage and Acuity Scale using a computer system, from which data were obtained and analyzed retrospectively. The primary outcome measure was the percentage of children hospitalized related with PAT findings. The secondary outcome measures were the admission to the intensive care unit (%), PED length of stay, and performance of blood tests (%). RESULTS: Among the 302,103 episodes included, there were abnormal PAT findings in 24,120 cases (7.9%). Multivariate analysis adjusted for age confirmed that PAT findings and triage level were independent risk factors for admission (odds ratio [OR], 2.21; 95% confidence interval [CI], 2.13-2.29; OR, 6.01; 95% CI, 5.79-6.24, respectively). Abnormal findings in appearance or in more than 1 PAT component were even more strongly associated with admission (3.99; 95% CI, 3.63-4.38; 14.99, 95% CI, 11.99-18.74, respectively). When adjusted for triage level and age, abnormal PAT findings were also an independent risk factor for intensive care unit admission (OR, 4.44; 95% CI, 3.77-5.24) and a longer stay in the PED (OR, 1.78; 95% CI, 1.72-1.84). CONCLUSIONS: Abnormal findings in the PAT applied by trained nurses at triage identify patients with a higher risk of hospitalization. The PAT seems to be a valid tool for identifying the most severe patients as a first step in the triage process.

BACKGROUND: While several studies have reported a link between the presence of gout and adverse cardiovascular (CV) events in the general population, none has addressed the question of whether the mortality risk of patients with gout is influenced by disease severity. METHODS: We applied survival analysis methodology to prospectively collected data on clinical and radiographic measures of disease severity and mortality in a specialty clinic based cohort of 706 patients with gout (1992-2008). Standardised mortality ratios (SMR) were calculated to assess the magnitude of excess mortality among patients with gout compared with the underlying general population. RESULTS: Mean follow-up was 47 months. Tophaceous deposition was present in 30.5% of patients; >4 joints were involved in 34.6% of cases. Mean annual flare rate was 3.4. Arterial hypertension (41.2%), hyperlipidaemia (42.2%), diabetes mellitus (20.1%), renal function impairment (26.6%) and a previous CV event (25.3%) were recorded. 64 (9.1%) patients died, death being attributed to vascular causes in 38 (59%) patients. SMR for gout patients was 2.37 (95% CI 1.82 to 3.03), 1.57 (1.18 to 2.05) and 4.50 (2.06 to 8.54) overall, and in men and women, respectively. The presence of tophi and the highest baseline serum urate (SU) levels were independently associated with a higher risk of mortality, in addition to age, loop diuretic use and a history of a previous vascular event. In the multivariable survival regression models, with time varying covariates, the presence of tophi remained a significant mortality risk after adjustment for baseline SU levels (1.98; 1.24 to 3.20). CONCLUSIONS: High baseline SU level and the presence of subcutaneous tophi were both associated with an increased risk of mortality in patients with gout, in most cases attributed to a CV cause. This suggests a plausible pathophysiological link between greater total body urate load and CV disease.

Malnutrition occurs frequently in patients with cancer. Indeed, a variety of nutritional and tumor-related factors must be taken into account in these patients. Recognizing this relationship, we aimed to prospectively evaluate the risk factors that influence weight loss in patients undergoing radiotherapy with oral nutritional supplementation and dietetic counseling. Weight loss of 74 patients during radiotherapy and 1 month after treatment was analyzed. Parameters such as age, gender, tumor location, tumor stage, Eastern Cooperative Oncology Group performance status (ECOG PS) score, and the use of chemotherapy were analyzed to evaluate their influence on weight loss. All patients underwent oral nutritional supplementation and dietetic counseling. Forty-six (65.7%) patients lost weight, with a mean weight loss of (4.73 ± 3.91) kg, during radiotherapy. At 1 month after treatment, 45 (66.2%) patients lost weight, presenting a mean weight loss of (4.96 ± 4.04) kg, corresponding to a (6.84 ± 5.24)% net reduction from their baseline weight. Head and neck cancer patients had a mean weight loss of (3.25 ± 5.30) kg, whereas the remaining patients had a mean weight loss of (0.64 ± 2.39) kg (P = 0.028) during radiotherapy. In the multivariate analysis, the head and neck tumor location (P = 0.005), use of chemotherapy (P = 0.011), and ECOG PS score of 2-3 (P = 0.026) were considered independent risk factors. Nutritional status and parameters, such as tumor location (especially the head and neck), the use of chemotherapy, and the ECOG PS score, should be evaluated before radiotherapy because these factors can influence weight loss during radiotherapy and 1 month after treatment.

UNLABELLED: The study was performed to assess the usefulness of two new biomarkers, midregional pro-adrenomedullin (MR-pro-ADM) and C-pro-endothelin-1 (CT-pro-ET-1), in predicting bacterial infection (BI) and especially invasive bacterial infection (IBI) in well-appearing infants with fever without source (FWS). For this purpose, a multicenter prospective study was conducted between February 2008 and March 2009 including well-appearing infants less than 36 months of age with FWS. MR-pro-ADM, CT-pro-ET-1, procalcitonin (PCT), CRP, and WBC were measured and compared. Among the 1,035 infants included, a bacterial infection was diagnosed in 75 patients (7.2 %), and 16 (1.54 %) had an invasive bacterial infection (bacterial meningitis, 8; occult bacteremia, 6; and sepsis, 1). MR-pro-ADM and CT-pro-ET-1 levels were less reliable for diagnosis than the other biomarkers. The area under receiver operating characteristic curve for infants with BI and IBI was 0.59 (95 % confidence interval (CI) 0.52-0.67) and 0.63 (95 % CI 0.46-0.80) for MR-pro-ADM and 0.58 (95 % CI 0.51-0.66) and 0.62 (95 % CI 0.47-0.67) for CT-pro-ET-1, respectively. Multivariate analysis showed that PCT ≥ 0.5 ng/mL, CRP ≥ 40 mg/L, and CT-pro-ET-1 ≥ 105 pmol/mL were independent risk factors for having a BI (odds ratio (OR) 6.12, 3.61, and 2.84, respectively). PCT was the only independent risk factor for having an IBI (OR 17.53 if PCT ≥ 0.5 ng/mL). CONCLUSION: Although baseline MR-pro-ADM and CT-pro-ET-1 levels are significantly elevated in well-appearing febrile infants with a bacterial infection, their overall performance as diagnostic markers is very poor.

OBJECTIVES: To estimate the prevalence of Trypanosoma cruzi infection, the epidemiological factors associated with it, and the risk of maternal-foetal transmission in pregnant women from endemic areas seen in the catchment area of Cruces Hospital (Basque Country, Spain). METHODS: Descriptive study. Diagnosis of T. cruzi infection in pregnant women and neonates by performing serological tests and parasitological diagnosis using PCR. Epidemiological survey and multivariate analysis to identify the risk factors associated with T. cruzi infection. RESULTS: A total of 158 women participated in the study between December 2008 and January 2010, with mean age of 28.5 (±5.3). Nineteen (12%) pregnant mothers were seropositive, of whom 16 (84.2%) came from Bolivia, with a prevalence, in this group, of 22.2%. Independent epidemiological risk factors associated with T. cruzi infection were a history of living in mud houses (OR: 4.62; 95%IC: 1.54-13.87; P=.006) and knowledge of the vector (OR: 9.07; 95%IC: 1.91-43.11; P=.006). There was one newborn infected, which assumed a congenital transmission rate of 5.8% CONCLUSIONS: On the basis of the high prevalence of T. cruzi infection detected in Latin-American pregnant women and the risk of vertical transmission, a screening program would be recommended, which would be fundamentally based on the identification of geographic origin and epidemiological variables.

INTRODUCTION: The objectives of this study are to present the results of adrenalectomies due to metastasis, and to analyse the prognostic factors that may help to predict long-term survival in this patient group. PATIENTS AND METHODS: A retrospective study was conducted on 35 patients who underwent adrenalectomy for metastases in the Hospital de Cruces from 1996 to January 2010. The survival analysis was performed using the Kaplan and Meier method. RESULTS: Non-small cell lung cancer (NSCLC) was the most frequent primary tumour, with 18 cases. In 15 patients the diagnosis of adrenal metastasis was synchronous with the primary tumour, and in 20 cases it was metachronous. Only 7 patients survived without disease for 12, 22, 26, 58, 60, 65 and 120 months after the adrenalectomy. The disease free survival at 5 years was 16% in the whole series, and 27% in the NSCLC sub-group. None of the prognostic factors evaluated (size greater than 4.5 cm, cell type, differentiation grade, chemotherapy, surgical technique, disease free interval) was statistically significant in the overall survival, either in the general series or in the sub-group of patients with NSCLC. However, in the general series with tumour recurrence, the difference in survival between metachronous and synchronous metastasis was statistically significant (P=.05), in favour of the former. CONCLUSIONS: Adrenalectomy improves the expected survival particularly in patients with NSCLC. Patients with metachronous metastases do not have a higher rate of disease free survival at 5 years than those with synchronous metastases, although they do have a longer survival with the disease. When there is tumour recurrence, it is usually early.

AIM: To identify risk factors that influence weight loss in patients receiving radiotherapy. BACKGROUND: It is a well-known fact that cancer patients can be affected by malnutrition at the onset of the disease and during treatment due to the toxicity. Pretreatment weight loss alone does not predict those who will need nutritional supplementation. Instead, a variety of nutritional and tumor related factors needs to be taken into account. MATERIAL AND METHODS: A retrospective study was conducted on 129 patients with different tumor locations. Weight loss was evaluated during radiotherapy and one month after treatment. The impact of age, ECOG, chemotherapy, pretreatment weight loss, tumor location, previous surgery and TNM were analyzed. We aimed to identify a high-risk group of patients before starting treatment. RESULTS: The average net weight loss during radiotherapy and one month after treatment for this group of patients was 0.68 kg and 1.6 kg, respectively. Median weight loss during radiotherapy was 2.6 kg for head and neck (HN) patients and 0.27 kg for other tumor sites (p = 0.028). Median weight loss one month after radiotherapy was 3.7 kg for HN patients and 1.1 kg for the rest of the patients (p = 0.034). The median weight loss one month after treatment was 3.2 kg for patients receiving chemotherapy and 0.5 kg for those patients who did not receive chemotherapy (p < 0.001). A regression analysis determined that HN tumor location and the use of chemotherapy were independent risk factors. CONCLUSIONS: Nutritional status must be monitored and managed before, during and after treatment. A variety of nutritional and tumor-related factors must be considered. According to our results, head and neck tumors and the use of chemotherapy are the only two factors considered statistically significant. Because patients continue to lose weight after treatment, we recommend close surveillance after radiotherapy.
RESUMO
Objective: To analyse patterns of treatment with curative intent commonly used in elderly patients with locally advanced non-small-cell lung carcinoma (NSCLC) and predictive factors of overall survival in routine clinical practice. Methods: This multicentre prospective study included consecutive patients aged ≥65 years old diagnosed with NSCLC between February 2014 and January 2018. Inclusion criteria: age ≥65 years, stage IIIA/IIIB NSCLC. Treatment decisions were taken by a multidisciplinary committee. Kaplan-Meier curves and log-rank test were used to identify which clinical/treatment-associated variables, or pre-treatment quality of life (QOL) considering EORTC QLQ-C30 (and LC13 module) were predictive of overall survival. Results: A total of 139 patients were recruited. Median follow-up was 9.9 months (1.18-57.36 months) with a median survival of 14 months (range 11-17 months). In the group>75-year-old patients, the committee recommended chemotherapy and sequential radiotherapy (55.6%) or radiotherapy alone (22.2%), rather than surgery (3.7%) or concomitant radiochemotherapy (16.5%). However, in 65- to 75-year-old patients, surgery and concomitant radiochemotherapy were recommended in half of cases (p=0.003). Regarding multivariate analysis, the risk of death was higher in patients with pre-existing heart disease (p=0.002), low score for physical functioning (p=0.0001), symptoms of dysphagia (p=0,01), chest pain (p=0.001), and those not undergoing surgical treatment (p=0.024). Conclusions: Patients >75 years received more conservative treatments. Surgery improved survival and should be carefully considered, regardless of patient age. Comorbidities and poor baseline QOL are predictive of shorter survival. Advances in knowledge: Measuring these parameters before treatment may help us to define a population of frail patients with a poorer prognosis to facilitate decision making in clinical practice.
RESUMO
To investigate the outcome of temporal lobe epilepsy surgery and identify the variables which predict a good prognosis with respect to seizures in postoperative follow-up after two and four years. This retrospective study included 115 selected patients who underwent surgery for temporal lobe epilepsy between 1996 and 2007. In the second year after surgery 86.1% of patients had a good prognosis for seizure control (73.9% Engel class I and 12.2% Engel class II) and 89.2% (76.3% Engel class I and 12.9% Engel class II) in the fourth year. Sixty-four of 93 (68.8%) patients were free of disabling seizures (Engel class I) during the entire period and 78 (83.8%) had good prognosis (Engel class I and II). For the second year, logistic regression analysis revealed the following variables to be independently predictive of good seizure control: absence of two or more seizure episodes in the first year after surgery, normal postoperative video-EEG, and age at surgery of less than 35 years. In the fourth year, mesial temporal sclerosis, female sex and normal postoperative video-EEG were the predictive factors. For the group with a good prognosis in both the second and the fourth year, the predictive variables were: absence of two or more seizure episodes in the first year after surgery (OR: 13.762, CI 95%: 2.566-73.808, p<0.002) and normal postoperative video-EEG (OR: 16.301, CI 95%: 3.704-71.740, p<0.001). This study illustrates the sustained benefit of temporal lobe epilepsy surgery. The multivariate logistic regression analysis failed to identify a good predictive model composed of preoperative variables alone, although it was possible to build such a model with either pre- and postoperative variables or only postoperative variables.

We performed a quality improvement initiative to reduce unnecessary treatments for acute bronchiolitis (AB) in primary care (PC) and the referral paediatric emergency department (ED). The quality improvement initiative involved two seasons: 2016-2017 (preintervention) and 2017-2018 (postintervention). We distributed an evidence-based protocol, informative posters and badges with the slogan 'Bronchiolitis, less is more'. We also held interactive sessions, and paediatricians received weekly reports on bronchodilator prescription. The main outcome was the percentage of infants prescribed salbutamol. Secondary outcomes were epinephrine, antibiotic and corticosteroid prescription rates. Control measures were ED visit and hospitalisation rates, triage level, length of stay, intensive care admission and unscheduled returns with admission. We included 1878 ED and 1192 PC visits of which 855 (44.5%) and 534 (44.7%) occurred in the postintervention period, respectively. In the ED, salbutamol and epinephrine prescription rates fell from 13.8% (95% CI 11.8% to 16%) to 9.1% (95% CI 7.3% to 11.2%) (p<0.01) and 10.4% (95% CI 8.6% to 12.4%) to 9% (95% CI 7.2% to 11.1%) (n.s.), respectively. In PC, salbutamol, corticosteroid and antibiotic prescription rates fell from 38.3% (95% CI 34.6% to 42.0%) to 15.9% (95% CI 12.9% to 19.5%) (p<0.01), 12.9% (95% CI 10.5% to 15.7%) to 3.6% (95% CI 2.2% to 5.7%) (p<0.01) and 29.6% (95% CI 26.2% to 33.2%) to 9.5% (95% CI 7.2% to 12.5%) (p<0.01), respectively. No significant variations were noted in control measures. We safely decreased the use of unnecessary treatments for AB. Collaboration between PC and ED appears to be an important factor for success.

PURPOSE: Research on dose-effect correlation is necessary to move toward an individualization of treatments of metastatic castration resistant prostate cancer (mCRPC) with 223 Ra-Cl2 . We first looked for a possible correlation of 99m Tc-HDP lesion uptake in pretreatment whole-body scans (WBSs) with lesion absorbed dose. Moreover, we looked for a possible correlation of 99m Tc-HDP lesion uptake in pretreatment WBSs and of lesion absorbed dose with relative change in the 99m Tc-HDP lesion uptake obtained from pre- and post-treatment WBSs in patients treated for mCRPC with six cycles of 223 Ra-Cl2 . METHODS: Eleven patients received six cycles of 55 kBq/kg of 223 Ra-Cl2 separated by 4 weeks. In addition, one patient received concomitant treatment with abiraterone and two patients with enzalutamide. The 99m Tc-HDP WBSs were acquired before the first cycle and after the sixth cycle of the treatment. For the lesions with the higher 99m Tc-HDP uptake, the absorbed dose was calculated for the first cycle. Lesion volume was determined from 99m Tc-HDP SPECT/CT images before the first cycle and 223 Ra-Cl2 activity in the lesions was determined from 223 Ra-Cl2 planar images after the first cycle. The effect of the treatment was evaluated from the relative change of the mean and the maximum counts in the lesions, both estimated from the WBSs acquired before the first cycle and after the sixth cycle. RESULTS: The absorbed dose was calculated for 30 lesions, with values ranging between 0.4 and 3.8 Gy (mean 1.5 Gy). A significant (P < 0.05) high positive linear correlation was found between the lesion absorbed dose in the first treatment cycle and the mean and maximum counts in the lesions in the WBSs acquired before the first cycle (R = 0.75 and 0.76, respectively). The relative change of the mean and the maximum counts in the lesions in the 99m Tc-HDP WBSs showed a significant (P < 0.05) high positive logarithmic correlation with the 99m Tc-HDP mean and maximum counts in the lesions before the first cycle (R = 0.79 and 0.78, respectively). Lastly, a significant (P < 0.05) high positive logarithmic correlation was also found between the relative change of the mean and the maximum counts in the lesions in the 99m Tc-HDP WBSs and the lesion absorbed dose (R = 0.86 and 0.85, respectively). For this correlation the influence of the administered activity and of the concomitant treatments was not found to be significant (P > 0.05). CONCLUSIONS: The high correlations found for the 99m Tc-HDP lesion uptake before the first cycle lesion with the relative change in the 99m Tc-HDP lesion uptake after the six cycles of 223 Ra-Cl2 , and with the lesion absorbed dose in the first cycle show the potential of pretreatment 99m Tc-HDP imaging in order to personalize the performance of these treatments.

OBJECTIVES: To analyze the impact of an integrated care pathway on reducing unnecessary treatments for acute bronchiolitis. METHODS: We implemented an evidence-based integrated care pathway in primary care (PC) centers and the referral emergency department (ED). This is the third quality improvement cycle in the management of acute bronchiolitis implemented by our research team. Family and provider experiences were incorporated by using design thinking methodology. A multifaceted plan that included several quality improvement initiatives was adopted to reduce unnecessary treatments. The primary outcome was the percentage of infants prescribed salbutamol. Secondary outcomes were prescribing rates of other medications. The main control measures were hospitalization and unscheduled return rates. Salbutamol prescribing rate data were plotted on run charts. RESULTS: We included 1768 ED and 1092 PC visits, of which 913 (51.4%) ED visits and 558 (51.1%) PC visits occurred in the postintervention period. Salbutamol use decreased from 7.7% (interquartile range [IQR] 2.8-21.4) to 0% (IQR 0-1.9) in the ED and from 14.1% (IQR 5.8-21.6) to 5% (IQR 2.7-8) in PC centers. In the ED, the overall epinephrine use rate fell from 9% (95% confidence interval [CI], 7.2-11.1) to 4.6% (95% CI, 3.4-6.1) (P < .001). In PC centers, overall corticosteroid and antibiotic prescribing rates fell from 3.5% (95% CI, 2.2-5.4) to 1.1% (95% CI, 0.4-2.3) (P =.007) and from 9.5% (95% CI; 7.3-12.3) to 1.7% (95% CI, 0.9-7.3) (P <.001), respectively. No significant variations were noted in control measures. CONCLUSIONS: An integrated clinical pathway that incorporates the experiences of families and clinicians decreased the use of medications in the management of bronchiolitis.

OBJETIVES: To assess the incidence, related factors, timing and duration of new- onset atrial fibrillation in a cohort of consecutive patients diagnosed with pneumococcal pneumonia. METHODS: Observational study including all immunocompetent adults hospitalized for pneumococcal pneumonia. Patients were classified by time (atrial fibrillation recognized on emergency room arrival or developed during hospitalization) and duration (paroxysmal or persistent). Patients were followed-up for 6 months after discharge. RESULTS: We included 1092 patients, of whom 109 (9.9%) had new-onset atrial fibrillation. An early event was documented in 87 (79.8%) cases. Arrhythmia was classified as paroxysmal in 78 patients. Older age, heavy drinking, respiratory rate ≥ 30/minute, leukopenia, severe inflammation and bacteremia were independent risk factors for developing new-onset atrial fibrillation on admission. Overall, 48 (4.4%) patients died during hospitalization, the rate being higher in those patients who developed new-onset arrhythmia (17.9% vs 2.9% p<0.001). Among patients with events recognized at admission, in-hospital mortality was higher in those with persistent arrhythmia (34.8% vs 6.3%, pâ¯=â¯0.002) and 6-month survival was better among those who developed paroxysmal event. CONCLUSIONS: The development of new-onset atrial fibrillation was associated with pneumonia severity, and higher in-hospital mortality. Bacteremia and severe systemic inflammation were factors associated with its development.
