RESUMO

OBJECTIVE: The European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) recently released the first international consensus on the diagnostic criteria for Sarcopenic obesity (SO). The present study aimed to explore the ability of SO to predict the risk of pneumonia in patients with stable schizophrenia. METHODS: This was a prospective study involving hospitalized patients with schizophrenia aged ≥50 years from two mental health centers in western China. Baseline patient data were collected from September 1 to September 30, 2020. Follow-up data on pneumonia were collected from October 2020 to October 2022. The diagnosis of SO was based on the ESPEN/EASO criteria. Patients were assessed for handgrip strength (HGS), skeletal muscle mass/weight (SMM/W), and fat mass percentage (FM%). Logistic regression analysis was used to explore the effect of SO on the risk of pneumonia in patients with stable schizophrenia. RESULTS: A total of 320 patients with stable schizophrenia were included. Of these, 74 (23.13%) were diagnosed with SO, while 117 (36.56%) developed pneumonia. Compared with patients in the non-low HGS, non-low HGS + non-low SMM/W (or non-low HGS + low SMM/W or low HGS + non-low SMM/W) and non-SO groups, the proportions of patients with pneumonia in the low HGS (42.3% vs. 25.9%, p = 0.004), low HGS + low SMM/W (45.3% vs. 33.3%, p = 0.048), and SO (47.3% vs. 33.3%, p = 0.029) groups, respectively, were higher. However, there was no difference in the proportion of patients with pneumonia in the low SMM/W group and the obese group compared with the non-low SMM/W and non-obese groups. Further logistic regression analysis after adjustment for potential influencing factors showed that compared with the non-low HGS group, patients in the low HGS group had a higher risk of pneumonia (OR = 1.892, 95%CI: 1.096-3.264). CONCLUSION: SO defined according to the ESPEN/EASO criteria was not found to be significantly associated with the development of pneumonia in patients with stable schizophrenia. Further verification of these results is needed with larger sample sizes and the establishment of a cutoff value for this population.

RESUMO

INTRODUCTION: The Mann Assessment of Swallowing Ability (MASA) is a standardized clinical swallowing examination, specifically developed as a diagnostic test for the presence of oropharyngeal dysphagia and aspiration in the early period after stroke onset. In the original validation study, cutoff scores of <178 and <170 points, respectively, for the identification of dysphagia and aspiration risk are reported. However, a literature search revealed that alternative cutoff scores for dysphagia and/or aspiration provide better diagnostic accuracy. The aim of this secondary data analysis study was to evaluate the concurrent and predictive validity of the MASA. METHODS: Data were derived from a Belgian cohort study of an acute stroke population (n = 151). The MASA total score (MASA-TS), which is the sum of weighted scores on the 24 items, was evaluated against the Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS) to assess concurrent validity. To assess predictive validity of the MASA-TS, pneumonia during hospitalization and over 1 year and mortality acted as a future criterion. Analyses included receiver operating characteristic curves and area under the curve (AUC). RESULTS: Diagnostic accuracy of the MASA-TS was good for dysphagia (AUC = 0.85) and for the presence of relevant aspiration risk (AUC = 0.84). Using the original cutoff scores, the MASA-TS showed perfect sensitivity (Se = 1.00) for the identification of dysphagia and aspiration but inadequate specificity (Sp) for dysphagia (Sp = 0.16) and aspiration (Sp = 0.43). After determining new MASA cutoff scores, the optimal MASA cutoff scores were ≤146 for both dysphagia and aspiration with adequate thresholds (Se = 0.71 and Sp = 0.81 for dysphagia; Se = 0.73 and Sp = 0.80 for aspiration). The MASA-TS was a significant predictor of pneumonia during hospitalization (AUC = 0.85) and 1-year follow-up (AUC = 0.86), and of mortality (AUC = 0.79). CONCLUSION: The MASA-TS showed good concurrent validity with the FEDSS. Furthermore, using new cutoff scores (≤146 for the identification of dysphagia and aspiration) lead in general to more accurate diagnostic indexes. The MASA-TS is a good predictor of aspiration pneumonia during hospitalization and 1-year follow-up and of mortality.

RESUMO

OBJECTIVES: It remains unclear whether intraoperative lung-protective strategies can reduce the rate of respiratory complications after cardiac surgery, partly because low-risk patients have been studied in the past. The authors established a screening model to easily identify a high-risk group for severe pulmonary complications (ie, pneumonia or acute respiratory distress syndrome) that may be the ideal target population for the assessment of the potential benefits of such measures. DESIGN: Retrospective observational trial. SETTING: Departments of cardiac surgery and cardiac anesthesia of a university hospital. PARTICIPANTS: Consecutive patients undergoing cardiac surgery on cardiopulmonary bypass and subsequent treatment at a dedicated cardiosurgical intensive care unit between January 2019 and March 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 2,572 patients undergoing surgery, 84 (3.3%) developed pneumonia/acute respiratory distress syndrome that significantly affected the outcome (ie, longer ventilatory support [66% vs 11%], higher reintubation rate [39% vs 3%]), prolonged length of intensive care unit [33 ± 36 vs 4 ± 10 days] and hospital stay [10 ± 15 vs 6 ± 7 days], and higher in-hospital [43% vs 9%] as well as 30-day [7% vs 3%] mortality). The screening model for severe pulmonary complications included left ventricular ejection fraction <52%, EuroSCORE II (European System for Cardiac Operative Risk Evaluation II) >5.9, cardiopulmonary bypass time >123 minutes, left ventricular assist device or aortic repair surgery, and bronchodilatory therapy. A cutoff for the predicted risk of 2.5% showed optimal sensitivity and specificity, with an area under the receiver operating characteristic curve of 0.82. CONCLUSIONS: The authors suggest that future research on intraoperative lung-protective measures focuses on this high-risk population, primarily aiming to mitigate severe forms of postoperative pulmonary dysfunction associated with poor outcomes and increased resource consumption.

RESUMO

Background: Whether prophylactic administration of antibiotics to patients with influenza reduces the hospitalisation risk is unknown. We aimed to examine the association between antibiotic prescription in outpatients with influenza infection and subsequent hospitalisation. Methods: We conducted a cohort study using health insurance records of Japanese clinic and hospital visits between 2012 and 2016. Participants were outpatients (age, 0-74 years) with confirmed influenza infection who were prescribed anti-influenza medicine. The primary outcomes were the hospitalisation risk from all causes and pneumonia and the duration of hospitalisation due to pneumonia. Results: We analysed 903,104 outpatient records with 2469 hospitalisations. The risk of hospitalisation was greater in outpatients prescribed anti-influenza medicine plus antibiotics (0.31% for all causes and 0.18% for pneumonia) than in those prescribed anti-influenza medicine only (0.27% and 0.17%, respectively). However, the risk of hospitalisation was significantly lower in patients prescribed peramivir and antibiotics than in those prescribed peramivir only. Patients who received add-on antibiotics had a significantly longer hospital stay (4.12 days) than those who received anti-influenza medicine only (3.77 days). In all age groups, the hospitalisation risk from pneumonia tended to be greater in those who received antibiotics than in those prescribed anti-influenza medicine only. However, among older patients (65-74 years), those provided add-on antibiotics had an average 5.24-day shorter hospitalisation due to pneumonia than those provided anti-influenza medicine only (not significant). Conclusions: In outpatient cases of influenza, patients who are prescribed antibiotics added to antiviral medicines have a higher risk of hospitalisation and longer duration of hospitalisation due to pneumonia.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common comorbidity in patients with nontuberculous mycobacterial lung disease (NTMLD). Both conditions are associated with increased morbidity and mortality, but data are lacking on the additional burden associated with NTMLD among patients with COPD. Thus, the goal of this study was to assess the incremental mortality risk associated with NTMLD among older adults with COPD. METHODS: A retrospective cohort study was conducted using the US Medicare claims database (2010-2017). Patients with preexisting COPD and NTMLD (cases) were matched 1:3 by age and sex with patients with COPD without NTMLD (control patients). Patients were followed up until death or data cutoff (December 31, 2017). Incremental risk of mortality was evaluated by comparing the proportions of death, annualized mortality rate, and mortality hazard rate between cases and control patients using both univariate and multivariate analyses adjusting for age, sex, comorbidities, and COPD severity. RESULTS: A total of 4,926 cases were matched with 14,778 control patients. In univariate analyses, a higher proportion of cases (vs. control patients) died (41.5% vs. 26.7%; P < 0.0001), unadjusted annual mortality rates were higher among cases (158.5 vs. 86.0 deaths/1000 person-years; P < 0.0001), and time to death was shorter for cases. This increased mortality risk was also reflected in subsequent multivariate analyses. Patients with COPD and NTMLD were more likely to die (odds ratio [95% CI], 1.39 [1.27-1.51]), had higher mortality rates (rate ratio [95% CI], 1.36 [1.28-1.45]), and had higher hazard of death (hazard ratio [95% CI], 1.37 [1.28-1.46]) than control patients. CONCLUSIONS: The substantial incremental mortality burden associated with NTMLD in patients with COPD highlights the importance of developing interventions targeting this high-risk group and may indicate an unmet need for timely and appropriate management of NTMLD.

RESUMO

BACKGROUND: Diabetes mellitus (DM) and obesity are associated with total knee arthroplasty (TKA) complications. Semaglutide, a medication for DM and weight loss, can potentially affect TKA outcomes. This study investigated whether semaglutide use during TKA demonstrates fewer: (1) medical complications; (2) implant-related complications; (3) readmissions; and (4) costs. METHODS: A retrospective query was performed using a National database to 2021. Patients undergoing TKA for osteoarthritis with DM and semaglutide use were successfully propensity score-matched to controls semaglutide = 7,051; control = 34,524. Outcomes included 90-day postoperative medical complications, 2-year implant-related complications, 90-day readmissions, in-hospital lengths of stay, and costs. Multivariate logistical regressions calculated odds ratios (ORs), 95% confidence intervals, and P values (P < .003 as significance threshold after Bonferroni correction). RESULTS: Semaglutide cohorts had higher incidence and odds of myocardial infarction (1.0 versus 0.7%; OR 1.49; P = .003), acute kidney injury (4.9 versus 3.9%; OR 1.28; P < .001), pneumonia (2.8 versus 1.7%; OR 1.67; P < .001), and hypoglycemic events (1.9 versus 1.2%; OR 1.55; P < .001), but lower odds of sepsis (0 versus 0.4%; OR 0.23; P < .001). Semaglutide cohorts also had lower odds of prosthetic joint infections (2.1 versus 3.0%; OR 0.70; P < .001) and readmission (7.0 versus 9.4%; OR 0.71; P < .001), and trended toward lower odds of revisions (4.0 versus 4.5%; OR 0.86; P = .02) and 90-day costs ($15,291.66 versus $16,798.46; P = .012). CONCLUSION: Semaglutide use during TKA decreased risk for sepsis, prosthetic joint infections, and readmissions, but also increased risk for myocardial infarction, acute kidney injury, pneumonia, and hypoglycemic events.

RESUMO

BACKGROUND: Nontuberculous mycobacterial lung disease (NTMLD) is a debilitating disease. Chronic obstructive pulmonary disease (COPD) is the leading comorbidity associated with NTMLD in the United States. Their similarities in symptoms and overlapping radiological findings may delay NTMLD diagnosis in patients with COPD. OBJECTIVE: To develop a predictive model that identifies potentially undiagnosed NTMLD among patients with COPD. METHODS: This retrospective cohort study developed a predictive model of NTMLD using US Medicare beneficiary claims data (2006 - 2017). Patients with COPD with NTMLD were matched 1:3 to patients with COPD without NTMLD by age, sex, and year of COPD diagnosis. The predictive model was developed using logistic regression modeling risk factors such as pulmonary symptoms, comorbidities, and health care resource utilization. The final model was based on model fit statistics and clinical inputs. Model performance was evaluated for both discrimination and generalizability with c-statistics and receiver operating characteristic curves. RESULTS: There were 3,756 patients with COPD with NTMLD identified and matched to 11,268 patients with COPD without NTMLD. A higher proportion of patients with COPD with NTMLD, compared with those with COPD without NTMLD, had claims for pulmonary symptoms and conditions, including hemoptysis (12.6% vs 1.4%), cough (63.4% vs 24.7%), dyspnea (72.5% vs 38.2%), pneumonia (59.2% vs 13.4%), chronic bronchitis (40.5% vs 16.3%), emphysema, (36.7% vs 11.1%), and lung cancer (15.7% vs 3.5%). A higher proportion of patients with COPD with NTMLD had pulmonologist and infectious disease (ID) specialist visits than patients with COPD without NTMLD (≥ 1 pulmonologist visit: 81.3% vs 23.6%, respectively; ≥ 1 ID visit: 28.3% vs 4.1%, respectively, P < 0.0001). The final model consists of 10 risk factors (≥ 2 ID specialist visits; ≥ 4 pulmonologist visits; the presence of hemoptysis, cough, emphysema, pneumonia, tuberculosis, lung cancer, or idiopathic interstitial lung disease; and being underweight during a 1-year pre-NTMLD period) predicting NTMLD with high sensitivity and specificity (c-statistic, 0.9). The validation of the model on new testing data demonstrated similar discrimination and showed the model was able to predict NTMLD earlier than the receipt of the first diagnostic claim for NTMLD. CONCLUSIONS: This predictive algorithm uses a set of criteria comprising patterns of health care use, respiratory symptoms, and comorbidities to identify patients with COPD and possibly undiagnosed NTMLD with high sensitivity and specificity. It has potential application in raising timely clinical suspicion of patients with possibly undiagnosed NTMLD, thereby reducing the period of undiagnosed NTMLD.

RESUMO

Acute respiratory distress syndrome (ARDS) caused by multilobar pneumonia (MLP) is markedly different from typical ARDS in pathology, imaging characteristics, and lung mechanics. Regional lung assessment is required. We aimed to analyze the relationship between two regional assessment tools, lung ultrasound (LUS) and electrical impedance tomography (EIT) during positive end-expiratory pressure (PEEP) titration, and determine an appropriate PEEP level. We conducted a prospective study of patients with ARDS caused by MLP with PaO2/FiO2 < 150 mmHg. All subjects were equipped with two EIT belts connected with a single EIT machine to measure upper and lower hemithorax impedance change alternatingly at each PEEP level. LUS score was simultaneously determined in chest wall regions corresponding to the EIT regions during PEEP titration. We acquired EIT and LUS data in eight regions of interest at seven PEEP levels in 12 subjects. Therefore, 672 pairs of data were obtained for analysis. There were significant relationships between LUS score and tidal impedance variation and pixel compliance (Cpix). The Spearman's rho between LUS score vs. tidal impedance variation and LUS score vs. the Cpix were - 0.142, P < 0.001, and - 0.195, P < 0.001, respectively. The relationship between the LUS score and Cpix remained the same at every PEEP level but did not reach statistical significance. The individual's mean expected PEEP by LUS was similar to the EIT [10.33(± 1.67) vs. 10.33(± 1.44) cm H2O, P = 0.15]. Regarding the MLP, the LUS scores were associated with EIT parameters, and LUS scores might proof helpful for finding individual PEEP settings in MLP.

RESUMO

INTRODUCTION: Postoperative pneumonia increases the risk of postsurgical mortality, making it a serious healthcare-associated complication. Children with preoperative neuromuscular impairments have a higher risk of postoperative pneumonia. Obesity is also a risk factor for postoperative pulmonary complications, including pneumonia. Moreover, obesity is increasingly prevalent among children living with a neurological diagnosis. Whether obesity increases the risk of postoperative pneumonia among children with neurologic diseases remains largely unknown. Therefore, we assessed the risk of postoperative pneumonia among children with neurologic diagnoses based on their obesity status. METHODS: We analyzed a retrospective cohort of children ≤18 years from the National Surgical Quality Improvement Program (2012-2019) database who underwent inpatient orthopedic surgery. We used Cox proportional regression model to estimate the hazard ratio for the association between neurologic disorders and postoperative pneumonia. In addition, we included an interaction term between body mass index and neurologic disorders to evaluate the moderating effect of obesity status and then performed stratified analyses to compare the magnitude of hazard ratios across body mass index subgroups. RESULTS: A total of 60 745 children underwent inpatient orthopedic surgery during the study period, of whom 43.6% were healthy weight and 30.8% overweight/obese. The median age was 13 years (Interquartile range: 8-15). The incidence of postoperative pneumonia was higher among healthy weight patients with neurologic disorders than healthy weight patients without any neurologic disorders [Hazard ratio: 3.55 vs. 0.34]. Furthermore, the association between neurologic disorders and postoperative pneumonia was strongest among overweight patients than healthy weight or obese patients [Hazard ratio:11.88 vs. 9.45 vs. 4.40]. This observation was consistent across the various neurologic disorders analyzed. CONCLUSION: Childhood obesity buffered the association between neurologic disorders and postoperative pneumonia, consistent with an 'obesity paradox'. Further research exploring the underlying mechanisms for the obesity paradox in children with neurologic disorders is warranted.

RESUMO

A pneumonia adquirida na comunidade (PAC) é a infecção aguda do parênquima pulmonar que ocorre no meio comunitário. A PAC representa a maior causa de morbidade e mortalidade em todo o mundo em crianças abaixo de cinco anos. Nesta faixa etária, a etiologia viral é a mais comum; porém, dentre as causas bacterianas, o Streptoccocus pneumoniae é o mais prevalente. As manifestações clínicas variam de acordo com o patógeno, hospedeiro e da gravidade da doença, sendo geralmente descrita com tosse, febre e desconforto respiratório. A PAC complicada é a pneumonia que, apesar do uso de antibióticos, evolui com complicações locais ou sistêmicas. Nos pacientes hospitalizados, as hemoculturas devem ser consideradas para auxiliar no diagnóstico etiológico e planejamento terapêutico. O tratamento inicial deve ser iniciado empiricamente com antibióticos. Caso haja necessidade de hospitalização, hemoculturas devem ser consideradas para auxiliar na propedêutica. Após implementação das vacinas pneumocócicas, principalmente após introdução da vacina pneumocócica 13 valente (PCV 13), houve redução significativa dos casos de pneumonia bacteriana e também da necessidade hospitalização. Diante de tal realidade, a elaboração do trabalho possui como objetivo a melhora dos procedimentos e a padronização dos atendimentos da população pediátrica com um quadro clínico sugestivo pneumonia adquirida na comunidade, que procura o serviço de Pronto Atendimento Infantil do Hospital do Servidor Público Municipal de São Paulo (HSPM), ao construir um protocolo clínico de atendimento específico para a doença. O presente trabalho objetiva elaborar um protocolo clínico de atendimento de pneumonia adquirida na comunidade no Hospital do Servidor Público Municipal de São Paulo, contribuindo na assistência médica dos pacientes pediátricos. Apesar do grande avanço com a introdução das vacinas pneumocócicas, a PAC ainda representa uma importante causa de mortalidade na população infantil, sendo fundamental a elaboração de protocolos clínicos para abordar corretamente os pacientes que recorrem a um Pronto Socorro Infantil. Protocolos clínicos são diretrizes fundamentadas nas melhores práticas para a abordagem e tratamento de determinadas doenças, baseadas em evidência científica. O presente trabalho objetiva a melhora dos procedimentos e a uniformização dos atendimentos da população pediátrica com pneumonia, que procura o serviço de Pronto Atendimento Infantil do Hospital do Servidor Público Municipal de São Paulo (HSPM), com a construção de um protocolo clínico de atendimento específico para a doença, a partir da revisão de literatura atualizada, cujo período de vigência seguirá os progressos científicos sobre o tema.

RESUMO

This study assessed the incidence rate of all-cause pneumonia (ACP) and invasive pneumococcal disease (IPD) and associated medical costs among individuals aged ≥16 in the German InGef database from 2016 to 2019. Incidence rate was expressed as the number of episodes per 100 000 person-years (PY). Healthcare resource utilisation was investigated by age group and by risk group (healthy, at-risk, high-risk). Direct medical costs per ACP/IPD episode were estimated as the total costs of all inpatient and outpatient visits. The overall incidence rate of ACP was 1345 (95% CI 1339-1352) and 8.25 (95% CI 7.76-8.77) per 100 000 PY for IPD. For both ACP and IPD, incidence rates increased with age and were higher in the high-risk and at-risk groups, in comparison to the healthy group. ACP inpatient admission rate increased with age but remained steady across age-groups for IPD. The mean direct medical costs per episode were €8075 (95% CI 7121-9028) for IPD and €1454 (95% CI 1426-1482) for ACP. The aggregate direct medical costs for IPD and ACP episodes were estimated to be €8.5 million and €248.9 million respectively. The clinical and economic burden of IPD and ACP among German adults is substantial regardless of age.

RESUMO

Purpose: To determine the clinical and economic impact of inhaled corticosteroid (ICS) withdrawal in Spanish patients with COPD receiving triple therapy (TT) with ICS, long-acting ß2-agonist (LABA), and long-acting muscarinic antagonist (LAMA). Patients and Methods: This was an observational, retrospective study of BIG-PAC database medical records. Patients aged ≥40 years receiving TT from 2016 to 2018 were followed for 1 year. Two cohorts were identified: patients continuing TT (ICS+LABA+LAMA), and patients receiving TT with ICS withdrawn (LABA+LAMA). Variables included medication, exacerbations (moderate and severe), pneumonia, mortality, health resource use (HRU), and cost per patient/year. Cohorts were compared using propensity score matching (PSM). Multivariate statistical analysis using analysis of covariance and Cox proportional risks was conducted. Results: Of 6541 patients included, 5740 (87.8%) continued TT and 801 (12.2%) had ICS withdrawn. Patients with ICS withdrawal were younger, had lower disease burden, higher ICS doses, and more exacerbations compared with those continuing ICS. PSM matched 795 patients in each cohort. Mean age was 68.5 years (SD: 11.2), 69.9% were male, and mean Charlson index was 2.0. Patients with ICS withdrawal had more total exacerbations in the 12 months following withdrawal compared with patients continuing TT (36.6% vs 31.4%; p=0.030). No significant differences were found for pneumonia (3.3% vs 3.6%; p=0.583) and mortality (9.9% vs 7.5%; p=0.092). Median time to first exacerbation was shorter in patients with ICS withdrawal compared with those continuing ICS (HR: 0.69, 95% CI: 0.57-0.83; p<0.001). Mean health cost per patient/year among patients with ICS withdrawal was higher than those continuing TT (€2993 vs €2130; p<0.001). Conclusion: ICS withdrawal in patients with COPD receiving TT was associated with increased exacerbations, HRU, and costs compared with continuing TT, with health and economic impacts on patients and the Spanish National Healthcare System, respectively. Pneumonia and mortality rates were similar between groups.

RESUMO

INTRODUCTION: The aim of this evaluation is to understand whether introducing stabilisation rooms equipped with pulse oximetry and oxygen systems to frontline health facilities in Ikorodu, Lagos State, alongside healthcare worker (HCW) training improves the quality of care for children with pneumonia aged 0-59 months. We will explore to what extent, how, for whom and in what contexts the intervention works. METHODS AND ANALYSIS: Quasi-experimental time-series impact evaluation with embedded mixed-methods process and economic evaluation. SETTING: seven government primary care facilities, seven private health facilities, two government secondary care facilities. TARGET POPULATION: children aged 0-59 months with clinically diagnosed pneumonia and/or suspected or confirmed COVID-19. INTERVENTION: 'stabilisation rooms' within participating primary care facilities in Ikorodu local government area, designed to allow for short-term oxygen delivery for children with hypoxaemia prior to transfer to hospital, alongside HCW training on integrated management of childhood illness, pulse oximetry and oxygen therapy, immunisation and nutrition. Secondary facilities will also receive training and equipment for oxygen and pulse oximetry to ensure minimum standard of care is available for referred children. PRIMARY OUTCOME: correct management of hypoxaemic pneumonia including administration of oxygen therapy, referral and presentation to hospital. SECONDARY OUTCOME: 14-day pneumonia case fatality rate. Evaluation period: August 2020 to September 2022. ETHICS AND DISSEMINATION: Ethical approval from University of Ibadan, Lagos State and University College London. Ongoing engagement with government and other key stakeholders during the project. Local dissemination events will be held with the State Ministry of Health at the end of the project (December 2022). We will publish the main impact results, process evaluation and economic evaluation results as open-access academic publications in international journals. TRIAL REGISTRATION NUMBER: ACTRN12621001071819; Registered on the Australian and New Zealand Clinical Trials Registry.

RESUMO

BACKGROUND: For adults with cerebral palsy (CP), fragility fractures may be a risk factor for pneumonia, a leading cause of death for this population; yet, the timing and complications are unknown. The objectives were to determine the 30-day pneumonia rate post-fracture and its association with mortality and incident cardiovascular events among adults with CP. METHODS: This retrospective cohort study used nationwide administrative claims data from 01/01/2012-12/31/2017 from a random 20% sample of the Medicare fee-for-service and Optum Clinformatics® Data Mart. Cohorts included ≥18 years of age with CP with an incident fragility fracture (CP + Fx) and comparison cohorts: CP without fractures (CPw/oFx) and without CP with an incident fragility fracture (w/oCP + Fx). Incidence rate (IR) of pneumonia 30-days post-fracture and IR ratios were estimated by age group: 18-40, 41-64, and ≥ 65 years. For CP + Fx, Cox regression examined the association between time-varying pneumonia (within 30-days post-fracture) with mortality and incidence of cardiovascular events 0-30-days and 31-365-days post-fracture. RESULTS: There were 3688 CP + Fx (mean [SD] age, 58.2 [14.9]; 56.4% women), 29,429 CPw/oFx (50.3 [15.8]; 45.9% women), and 363,995 w/oCP + Fx (65.9 [18.3]; 65.5% women). The IR of 30-day pneumonia for CP + Fx was similar across age groups (IR per 100 person-months, 8.4-11.0) and 1.77-16.18-fold higher (all P < 0.05) than comparison cohorts. Peri/post-fracture pneumonia was associated with an increased rate of mortality (30-day-adjusted HR [aHR] = 5.89, 95%CI = 3.54-9.81; 31-365-day aHR = 2.89, 95%CI = 2.13-3.92), congestive heart failure 0-30-days (aHR = 3.64, 95%CI = 2.01-6.57) and 31-365-days (time-dependent), myocardial infarction 31-365-days (aHR = 2.03, 95%CI = 1.11-3.71), and cerebrovascular disease 0-30-days (time-dependent), without evidence of effect modification by age, sex, or fracture site. CONCLUSIONS: Adults with CP are particularly vulnerable to 30-day risk of post-fracture pneumonia and its complications across the adult lifespan and not just in the elderly years.

RESUMO

Rationale: Invasive mechanical ventilation (IMV) may be burdensome for persons with advanced dementia. Research has shown that IMV use in persons with dementia has increased in the United States, Spain, and Canada. Objectives: To compare the outcomes and healthcare costs among hospitalized patients with advanced dementia treated with noninvasive ventilation (NIV) versus IMV. Methods: A retrospective cohort study was conducted among hospitalized patients aged 66 years and older with pneumonia, or septicemia with pneumonia, treated with either NIV or IMV between 2015 and 2017. Persons were included if they had Minimum Data Set (MDS) assessments between 1 and 120 days before hospitalization indicating that they had advanced dementia with four or more impairments in activities of daily living. Propensity-matched analysis was performed using clinical information from the MDS, Chronic Condition Warehouse indicators of chronic disease, and prior use measures. Main outcome measures were survival and healthcare costs up to 1 year after discharge. Results: Among 27,483 hospitalizations between 2015 and 2017, IMV was used in 12.5% and NIV in 8.2%. A propensity-matched model comparing IMV versus NIV using clinical data from the MDS, Chronic Condition Warehouse indicators of chronic diseases, and prior use revealed matches for 96.3% of hospitalizations with the use of IMV. NIV matched cases had a higher 30-day mortality rate compared with IMV cases (58.7% vs. 51.9%, P ⩽ 0.001), but this survival benefit did not persist, as 1-year mortality was slightly higher among subjects with IMV compared with those with NIV (86.5% vs. 85.9%, P > 0.05). One-year healthcare costs after matching were higher among those treated with IMV compared with NIV (mean, $57,122 vs. $33,696; P < 0.001). Conclusions: Among patients with advanced dementia hospitalized with pneumonia or septicemia with pneumonia, improvement in 30-day survival for those treated with IMV compared with NIV must be weighed against lack of 1-year survival benefit and substantially higher costs.

Es notable el reporte de estos enfermos, la existencia de complicaciones favorecedoras de situaciones de amenaza vital y las diferencias hemogasométricas y en otros parámetros bioquímicos. Objetivo: Caracterizar aspectos clínicos, epidemiológicos y humorales de enfermos con la COVID-19 durante su estadía en la unidad de cuidados intensivos. Métodos: Se realizó un estudio descriptivo y transversal en 9 pacientes con la COVID-19 ingresados en la unidad de cuidados intensivos, de marzo a mayo de 2020. Los datos se obtuvieron de las historias clínicas. La información procesada se expresó en frecuencias absolutas y porcientos y los resultados se reflejaron en tablas y gráficos. Entre las variables analizadas figuraron: la edad, sexo, estado clínico y al egreso de los pacientes y la letalidad. Resultados: Predominaron los hombres (77,8 por ciento), las mujeres evolucionaron mejor (33,3 por ciento graves, ninguna crítica). El 88,8 por ciento de los enfermos tenían al menos una enfermedad crónica asociada. El 33,3 por ciento de los pacientes fueron asintomáticos al ingreso, la neumonía grave y el síndrome de distrés respiratorio agudo, fueron la causa más frecuente de complicación. Conclusiones: Los pacientes fueron mayoría del sexo masculino y todos los críticos fueron de este sexo; con proporciones similares en los grupos etarios; con comorbilidades, el mayor porcentaje, fundamentalmente hipertensión arterial; al ingreso presentaron tos, fiebre, disnea y decaimiento. Todos los críticos demoraron 4 días o más en solicitar asistencia médica. El motivo de ingreso a cuidados intensivos fue la neumonía grave/síndrome de dificultad respiratoria del adulto (AU)


Introduction: Researchers warn of people with severe forms of COVID-19. It is notable the report of these patients, the existence of complications favoring life-threatening situations and the hemogasometric differences and in other biochemical parameters. Objective: To characterize clinical, epidemiological and humoral aspects of patients with COVID-19 during their stay in the intensive care unit. Methods: A descriptive and cross-sectional study was carried out in 9 patients with COVID-19 admitted to the intensive care unit from March to May 2020. Data were obtained from medical records. The processed information was expressed in absolute frequencies and percentages and the results were reflected in tables and graphs. Among the variables analyzed were: age, sex, clinical status and at discharge of the patients and fatality. Results: Men predominated (77,8 percent), women evolved better (33,3 percent serious, no critical). 88,8 percent of the patients had at least one associated chronic disease. 33,3 percent of the patients were asymptomatic upon admission, severe pneumonia and acute respiratory distress syndrome were the most frequent cause of complication. Conclusions: Most of the patients were male and all the critics were male; with similar proportions in age groups; with comorbidities the highest percentage, mainly hypertension; on admission they presented cough, fever, dyspnea and decay; all critical patients took 4 days or more to request medical assistance. The reason for admission to the intensive care unit was severe pneumonia/adult respiratory distress syndrome(AU)

RESUMO

The aim of this study was to estimate the trends and burdens associated with systemic therapy-related hospitalizations, using nationally representative data. National Inpatient Sample data from 2005 to 2016 was used to identify systemic therapy-related complications using ICD-9 and ICD-10 external causes-of-injury codes. The primary outcome was hospitalization rates, while secondary outcomes were cost and in-hospital mortality. Overall, there were 443,222,223 hospitalizations during the study period, of which 2,419,722 were due to complications of systemic therapy. The average annual percentage change of these hospitalizations was 8.1%, compared to - 0.5% for general hospitalizations. The three most common causes for hospitalization were anemia (12.8%), neutropenia (10.8%), and sepsis (7.8%). Hospitalization rates had the highest relative increases for sepsis (1.9-fold) and acute kidney injury (1.6-fold), and the highest relative decrease for dehydration (0.21-fold) and fever of unknown origin (0.35-fold). Complications with the highest total charges were anemia ($4.6 billion), neutropenia ($3.0 billion), and sepsis ($2.5 billion). The leading causes of in-hospital mortality associated with systemic therapy were sepsis (15.8%), pneumonia (7.6%), and acute kidney injury (7.0%). Promoting initiatives such as rule OP-35, improving access to and providing coordinated care, developing systems leading to early identification and management of symptoms, and expanding urgent care access, can decrease these hospitalizations and the burden they carry on the healthcare system.

RESUMO

OBJECTIVE: In Indonesia, no study has been published to evaluate the utility scores among children with pneumonia. This study aims to quantify the health-related quality of life (HRQOL) of children with pneumonia in Indonesia using the EuroQoL Descriptive System (EQ-5D-5L) value set for Indonesia. METHODS: A hospital-based cross-sectional survey was conducted between September 2017 and March 2018. Children aged <14 years old who were hospitalized for pneumonia in 11 hospitals in Yogyakarta were recruited for this study. The EQ-5D-5L and visual analogue scale (EQ-VAS) were applied to the parents (proxy-assessment). RESULTS: A total of 384 patients were hospitalized with pneumonia. Among those patients, 338 (88.02%) were without congenital diseases; and 46 (11.98%) were with congenital diseases. The mean of utility scores in all patients was 0.67 ± 0.28, while the mean of visual analog scale (VAS) score was 67.66 ± 21.98. The mean of utility scores and VAS scores decreased among those with congenital diseases, which is 0.51 ± 0.51 and 65.41 ± 19.42, respectively. However, the utility score and VAS scores among patients without congenital diseases were higher than the category of all patients. Showing the number of,0.69 ± 0.23 and 68.0 ± 22.3, respectively. CONCLUSIONS: This study confirmed that children with pneumonia had a negative impact on HRQOL. The HRQOL could be used for future economic evaluation studies.

RESUMO

BACKGROUND: Lung involvement in patients with coronavirus disease 2019 (COVID-19) undergoing PET-CT has been previously reported. However, FDG uptake outside lung parenchyma was poorly characterized in detail. We evaluated the extra-parenchymal lung involvement in asymptomatic cancer patients with COVID-19 pneumonia through 18F-FDG PET-CT. METHODS: A total of 1079 oncologic 18F-FDG PET-CT were performed between February 2 and May 18, 2020. Confirmed COVID-19 pneumonia was defined as characteristic ground-glass bilateral CT infiltrates and positive genetic/serologic tests. Nonmetastatic extra-parenchymal lung PET-CT findings were evaluated through qualitative (visual), quantitative (measurements on CT), and semiquantitative (maximum standardized uptake value: SUVmax on PET) interpretation. Clinical data, blood tests, and PET-CT results were compared between patients with and without COVID-19 pneumonia. RESULTS: A total of 23 18F-FDG PET-CT scans with pulmonary infiltrates suggestive of COVID-19 and available laboratory data were included: 14 positive (cases) and 9 negative (controls) for COVID-19 infection, representing a low prevalence of COVID-19 pneumonia (1.3%). Serum lactate dehydrogenase and D-dimers tended to be increased in COVID-19 cases. Extra-parenchymal lung findings were found in 42.9% of patients with COVID-19, most frequently as mediastinal and hilar nodes with 18F-FDG uptake (35.7%), followed by incidental pulmonary embolism in two patients (14.3%). In the control group, extra-pulmonary findings were observed in a single patient (11.1%) with 18F-FDG uptake located to mediastinal, hilar, and cervical nodes. Nasopharyngeal and hepatic SUVmax were similar in both groups. CONCLUSION: In cancer patients with asymptomatic COVID-19 pneumonia, 18F-FDG PET-CT findings are more frequently limited to thoracic structures, suggesting that an early and silent distant involvement is very rare. Pulmonary embolism is a frequent and potentially severe finding raising special concern. PET-CT can provide new pathogenic insights about this novel disease.

RESUMO

The novel coronavirus, SARS-CoV-2, that causes the COVID-19 disease currently has healthcare systems around the world dealing with unprecedented numbers of critically ill patients. One of the primary concerns associated with this illness is acute respiratory distress syndrome (ARDS) and the pneumonia that accompanies it. Historical literature dating back to the 1940s and earlier contains many reports of successful treatment of pneumonias with ionizing radiation. Although these were not randomized controlled trials, they do suggest a potential avenue for further investigation. Technical details in these reports however were limited. In this work we review the literature and identify details including nominal kilovoltage ranges, filtration, and focus-skin distances (FSDs). Using a freely available and benchmarked code, we generated spectra and used these as sources for Monte Carlo simulations using the EGSnrc software package. The approximate sources were projected through a radiologically anthropomorphic phantom to provide detailed dose distributions within a targeted lung volume (approximate right middle lobe). After accounting for the reported exposure levels, mean lung doses fell in a relatively narrow range: 30-80 cGy. Variation in patient dimensions and other details are expected to result in an uncertainty on the order of ± 20%. This result is consistent with the dose range expected to induce anti-inflammatory effects.
