Reverse J-shaped relationship between body mass index and in-hospital mortality of patients hospitalized for heart failure in Japan. Heart Vessels 2020; 36:383-392. [PMID: 32980921 DOI: 10.1007/s00380-020-01699-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 09/04/2020] [Indexed: 01/18/2023]
Abstract
Several lines of evidence demonstrated body mass index (BMI) to be inversely associated with outcomes of patients with HF, so-called obesity paradox. However, the relationship between BMI and outcomes of patients with HF in Japan has been poorly understood. This study sought to explore the relationship between BMI and in-hospital mortality of patients hospitalized for heart failure (HF) in Japan and whether BMI at hospital admission could be used for the risk stratification of hospitalized HF patients. We studied 407,722 patients hospitalized for HF between January 2010 and March 2018, using the Diagnosis Procedure Combination database, a national inpatient database in Japan. Patients were categorized into four groups: underweight (BMI < 18.5 kg/m2), 66,342 patients (16.3%); normal (18.5-24.9 kg/m2), 240,801 patients (59.1%); pre-obesity (25.0-29.9 kg/m2), 76,954 patients (18.9%); and obesity (≥ 30.0 kg/m2), 23,625 patients (5.8%). Pre-obese and obese patients were younger and more likely to be male. Advanced HF symptoms were more common among underweight patients. Multivariable logistic regression analysis fitted with generalized estimating equation showed that, compared with normal weight patients underweight patients had higher in-hospital mortality (odds ratio 1.50, 95% confidence interval 1.45-1.55), whereas pre-obese patients (odds ratio 0.80, 95% confidence interval 0.77-0.83) and obese patients (odds ratio 0.90, 95% confidence interval 0.84-0.97) had lower in-hospital mortality. Restricted cubic spline showed a reverse J-shaped relationship between BMI and in-hospital mortality with the bottoms of splines around BMI 26 kg/m2. In conclusion, underweight patients had higher, and pre-obese and obese patients had lower in-hospital mortality compared to patients with normal weight patients. Furthermore, restricted cubic spline indicated a reverse J-shaped relationship between BMI and in-hospital mortality. Our findings are informative for the risk stratification of patients hospitalized for HF according to BMI.

Association between the number of hospital admissions and in-hospital outcomes in patients with heart failure. Hypertens Res 2020; 43:1385-1391. [PMID: 32655133 DOI: 10.1038/s41440-020-0505-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Revised: 05/18/2020] [Accepted: 06/03/2020] [Indexed: 11/08/2022]
Abstract
Readmission to the hospital is a major issue in clinical care for patients with heart failure (HF). However, the impact of the number of hospital admissions due to worsened HF is not fully understood. We sought to clarify the association between the number of hospital admissions due to worsened HF and patient outcomes. We studied 331,259 patients (median age was 81 years, and 175,286 patients (52.9%) were men) hospitalized for HF between January 2010 and March 2018 using the Japanese Diagnosis Procedure Combination Database, a national inpatient database. Patients were categorized into five groups based on the number of times they were admitted: once (n = 264,583), twice (n = 42,385), three times (n = 13,205), four times (n = 5347), and five or more times (n = 5739). The patients with larger numbers of admissions were more likely to have comorbidities and to use inotropic agents. The interval period between hospitalizations was shortened with an increasing number of hospital admissions, whereas the length of hospital stay was prolonged with an increasing number of hospital admissions. Multivariable logistic regression analysis fitted with a generalized estimating equation showed that an increased number of hospital admissions was independently associated with higher in-hospital mortality. In conclusion, readmission to the hospital due to worsened HF was still common, and in-hospital mortality was higher in those with larger numbers of readmissions, suggesting a clinical significance of the number of readmissions in patients with HF.

Abstract
Objective Unlike for patients with other forms of cardiomyopathies, those with severe ventricular dysfunction due to Duchenne muscular dystrophy (DMD) are not offered implantable cardioverter-defibrillator (ICD) therapy routinely. This prospective study aimed to determine the views of DMD-patients and their carers about discussing sudden death risk and their acceptance of ICDs. Design and setting Adults with DMD (n=9) and parents/carers (n=9) participated in audio-recorded, 60–90 min focus group sessions (patients 2; parents/carers 2) conducted through either a face-to-face session at a neutral venue or a videoconference. Sessions were facilitated by a clinical psychologist, experienced in conducting focus group research. All participants understood the rationale for the study and the nature of ICD therapy. The same predefined themes were explored with each group. Recordings were transcribed, analysed thematically by two researchers, working independently and then agreed. Differences in responses between patient and carer groups were also studied and compared. Participants all provided informed written consent and the study had ethical approval. Results Three main themes emerged: (1) access to/quality of information provided by professionals and patient engagement with them; (2) decision-making about ICDs; (3) individuals’ own ‘lived experience’ of DMD. Conclusions The main findings were: (1) patients with DMD want to have their risk of sudden arrhythmic death discussed, when relevant and (2) if ICD therapy were established as beneficial, they would welcome an individualised discussion about its appropriateness for them.

Abstract
BACKGROUND Using synthetic antibiotic-eluting envelope (ABE) is an effective intervention for prevention of cardiovascular implantable electronic device (CIED) infection. The biologic extracellular-matrix envelope (ECME), may offer potential advantages over the synthetic ABE. To further minimize the risk of infection, the ECME can be hydrated in gentamicin prior to CIED implantation. We aimed to evaluate the efficacy and pharmacokinetics (PK) of gentamicin containing ECME in an animal model. METHODS For all experiments, the ECME was hydrated in gentamicin (40 mg/Ml) (treatment) for 2 min. In vitro antimicrobial efficacy against six different bacterial species was assessed. In vivo experiments were conducted using a rabbit model of CIED pocket infection. Serum and ECM gentamicin concentrations were measured. Five different organisms were inoculated into the device pocket of control (ECME hydrated in 0.9% saline) and treatment groups. Macroscopic appearance and colony forming units from CIED, ECME, and tissue were determined. RESULTS No bacteria were recovered from any culture after 12 h of exposure to the gentamicin containing ECME. Serum gentamicin levels dropped below the limit of quantification at 15 h after implant. Gentamicin concentration in the ECME remained relatively stable for up to 7 days. Signs of clinical infection were observed in the control but not in the treatment group. In the presence of gentamicin, statistically significant reduction was demonstrated across all tested bacterial species. CONCLUSIONS In this preclinical animal infection model, gentamicin containing ECME was highly effective in reducing bacterial burden in the implant pocket, while systemic exposure after implantation remained low.

Front Surg 2018; 5:49. [PMID: 30105227 PMCID: PMC6077194 DOI: 10.3389/fsurg.2018.00049] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Accepted: 07/10/2018] [Indexed: 11/17/2022] Open
Abstract
Objective: One of the late-onset complications of cardiac implanted electronic devices (CIEDs) is central venous obstruction (CVO). The aim of this study was to investigate the feasibility, efficacy, and safety of endovascular treatment of CIED-related CVOs. Methods:Eighteen patients who underwent endovascular management of their device-related CVO were reviewed. Patients were classified into three groups: Group I patients were asymptomatic and needed lead replacement; Group II patients presented with symptomatic CVO without lead dysfunction, and Group III patients were referred with both symptomatic CVO and lead dysfunction. A treatment strategy involved recanalization and balloon angioplasty for Group I and angioplasty/stents for Groups II and III. Technical success, clinical success, complications, and long-term follow-up were assessed. Results: Thirteen patients were in Group I, four in Group II, and one in Group III. Technical and clinical success was achieved in 17 patients (94%). No major complications were reported. Restenosis was observed in two patients at 40 and 42 weeks of follow-up, and these patients were successfully treated with angioplasty. Conclusion: Endovascular management of CVO due to CIED is a safe and efficient technique. Plain balloon angioplasty is sufficient for lead replacement purposes, while stenting is needed for symptomatic CVO to achieve good long-term patency.
