OBJECTIVES: To evaluate the effect of an urban house calls program (HCP) on healthcare utilization. DESIGN: Retrospective chart review with pre/post analysis. SETTING: Urban home‐based primary care program. PARTICIPANTS: All participants (N=179) in a capitated insurance program enrolled in a HCP between October 2004 and August 2006. INTERVENTION: Enrollment into HCP. MEASUREMENTS: Hospitalizations and skilled nursing facility (SNF) admissions before and after enrollment. Patients with at least one hospitalization or SNF admission before and after enrollment were compared using the McNemar test. Median number of hospitalizations and SNF placements before and after HCP enrollment were compared using the Wilcoxon signed‐rank sum test. RESULTS: Sixty‐one percent of patients had one or more hospitalizations before enrollment, whereas only 38% had one or more hospitalizations after enrollment (P<.001). Thirty‐eight percent of patients had at least one SNF placement before enrollment, compared with 18% after enrollment (P=.001). The median hospitalization rate decreased from 1 to 0; the median SNF placement rate was 0 (interquartile range 0–1) before enrollment and 0 (interquartile range 0–0) after enrollment (P<.001). CONCLUSION: A HCP may be associated with fewer hospitalizations and SNF placements. Models of care that reduce morbidity and preserve quality of life are critical to help homebound older adults remain in their communities.  相似文献

OBJECTIVES: To evaluate the relationship between two methods to communicate treatment preferences (Physician Orders for Life‐Sustaining Treatment (POLST) program vs traditional practices) and documentation of life‐sustaining treatment orders, symptom assessment and management, and use of life‐sustaining treatments. DESIGN: Retrospective observational cohort study conducted between June 2006 and April 2007. SETTING: A stratified, random sample of 90 Medicaid‐eligible nursing facilities in Oregon, Wisconsin, and West Virginia. PARTICIPANTS: One thousand seven hundred eleven living and deceased nursing facility residents aged 65 and older with a minimum 60‐day stay. MEASUREMENTS: Life‐sustaining treatment orders; pain, shortness of breath, and related treatments over a 7‐day period; and use of life‐sustaining treatments over a 60‐day period. RESULTS: Residents with POLST forms were more likely to have orders about life‐sustaining treatment preferences beyond cardiopulmonary resuscitation than residents without (98.0% vs 16.1%, P<.001). There were no differences between residents with and without POLST forms in symptom assessment or management. Residents with POLST forms indicating orders for comfort measures only were less likely to receive medical interventions (e.g., hospitalization) than residents with POLST full treatment orders (P=.004), residents with traditional do‐not‐resuscitate orders (P<.001), or residents with traditional full code orders (P<.001). CONCLUSION: Residents with POLST forms were more likely to have treatment preferences documented as medical orders than those who did not, but there were no differences in symptom management or assessment. POLST orders restricting medical interventions were associated with less use of life‐sustaining treatments. Findings suggest that the POLST program offers significant advantages over traditional methods to communicate preferences about life‐sustaining treatments.  相似文献

The association of different antihypertensive regimens with blood pressure (BP) control is not well‐described among community‐dwelling older adults with low comorbidity. We examined antihypertensive use and BP control in 10 062 treated hypertensives from Australia and the United States (US) using baseline data from the ASPirin in Reducing Events in the Elderly (ASPREE) trial. Renin‐angiotensin system (RAS) drugs were the most prevalently used antihypertensive in both countries (Australia: 81.7% of all regimens; US: 62.9% of all regimens; P < .001). Diuretics were the next most commonly used antihypertensive in both countries, but were more often included in regimens of US participants (48.9%, vs 33.3% of regimens in Australia; P < .001). Among all antihypertensive classes and possible combinations, monotherapy with a RAS drug was the most common regimen in both countries, but with higher prevalence in Australian than US participants (35.9% vs 20.9%; P < .001). For both monotherapy and combination users, BP control rates across age, ethnicity, and sex were consistently lower in Australian than US participants. After adjustment for age, sex, ethnicity, and BMI, significantly lower BP control rates remained in Australian compared to US participants for the most commonly used classes and regimens (RAS blocker monotherapy: BP control = 45.5% vs 54.2%; P = .002; diuretic monotherapy: BP control = 45.2% vs 64.5%; P = .001; and RAS blocker/diuretic combo: BP control = 50.2% vs 65.6%; P = .001). Our findings highlight variation in antihypertensive use in older adults treated for hypertension, with implications for BP control. Differences in BP control that were observed may be influenced, in part, by reasons other than choice of specific regimens.  相似文献

The objectives of this study were to compare indices of 24‐hour blood pressure (BP) following a physician‐pharmacist collaborative intervention and to describe the associated changes in antihypertensive medications. This was a secondary analysis of a prospective, cluster‐randomized clinical trial conducted in 6 family medicine clinics randomized to co‐managed (n=3 clinics, 176 patients) or control (n=3 clinics, 198 patients) groups. Mean ambulatory systolic BP (SBP) was significantly lower in the co‐managed vs the control group: daytime BP 122.8 mm Hg vs 134.4 mm Hg (P<.001); nighttime SBP 114.8 mm Hg vs 123.7 mm Hg (P<.001); and 24‐hour SBP 120.4 mm Hg vs 131.8 mm Hg (P<.001), respectively. Significantly more drug changes were made in the co‐managed than in the control group (2.7 vs 1.1 changes per patient, P<.001), and there was greater diuretic use in co‐managed patients (79.6% vs 62.6%, P<.001). Ambulatory BPs were significantly lower for the patients who had a diuretic added during the first month compared with those who never had a diuretic added (P<.01). Physician‐pharmacist co‐management significantly improved ambulatory BP compared with the control group. Antihypertensive drug therapy was intensified much more for patients in the co‐managed group.  相似文献

Blood pressure (BP) changes and risk factors associated with pulse pressure (PP) increase in elderly people have rarely been studied using ambulatory blood pressure monitoring (ABPM). The aim is to evaluate 10‐year ambulatory blood pressure (ABP) changes in older hypertensives, focusing on PP and its associations with mortality. An observational study was conducted on 119 consecutive older treated hypertensives evaluated at baseline (T0) and after 10 years (T1). Treatment adherence was carefully assessed. The authors considered clinical parameters at T1 only in survivors (n = 87). Patients with controlled ABP both at T0 and T1 were considered as having sustained BP control. Change in 24‐hour PP between T0 and T1 (Δ24‐hour PP) was considered for the analyses. Mean age at T0: 69.4 ± 3.7 years. Females: 57.5%. Significant decrease in 24‐hour, daytime, and nighttime diastolic BP (all P < .05) coupled with an increase in 24‐hour, daytime, and nighttime PP (all P < .05) were observed at T1. Sustained daytime BP control was associated with lower 24‐hour PP increase than nonsustained daytime BP control (+2.23 ± 9.36 vs +7.79 ± 8.64 mm Hg; P = .037). The association between sustained daytime BP control and Δ24‐hour PP remained significant even after adjusting for age, sex, and 24‐hour PP at T0 (β=0.39; P = .035). Both 24‐hour systolic BP and 24‐hour PP at T0 predicted mortality (adjusted HR 1.07, P = .001; adjusted HR 1.25, P < .001, respectively). After ROC comparison (P = .001), 24‐hour PP better predicted mortality than 24‐hour systolic BP. The data confirm how ABP control affects vascular aging leading to PP increase. Both ambulatory PP and systolic BP rather than diastolic BP predict mortality in older treated hypertensives.  相似文献

This retrospective claims database analysis compared two strategies of hypertension treatment in outpatient, emergency, and inpatient departments: a fixed‐dose combination (FDC) of amlodipine/valsartan vs free combinations of angiotensin receptor blockers (ARBs) and calcium channel blockers (CCBs) (ARB+CCB group). After a mean follow‐up of 15.2 months, the FDC group had significantly lower total healthcare costs (US $1844 vs US $2158; P<.001) and hospitalization rates (14.57% vs 18.43%; P<.001), a higher proportion of days covered (80.35% vs 72.57%; P<.001), and better persistence (266 vs 225 days; P<.001) compared with the ARB+CCB group. The FDC group also had a better major adverse cardiovascular event (MACE)–free survival (hazard ratio, 0.83; 95% confidence interval, 0.73–0.94; P=.003) and decreased rates of heart failure (2.12% vs 3.26%; P<.001), malignant dysrhythmia (0.18% vs 0.42%; P=.021), and percutaneous coronary intervention (0.76% vs 1.26%; P=.015). Compared with free combinations of ARB+CCB, an FDC of amlodipine/valsartan improved MACE‐free survival and medication compliance and decreased total healthcare costs and hospitalization rates in hypertensive patients.  相似文献

Postacute care (PAC) is an important source of cost growth and variation in the Medicare program and is critical to accountable care organization (ACO) and bundled payment efforts to improve quality and value in the Medicare program, but ACOs must often look outside their walls to identify high‐value external PAC partners, including skilled nursing facilities (SNFs). As a solution to this problem, the integrated health system, Partners HealthCare System (PHS) and its Pioneer ACO launched the PHS SNF Collaborative Network in October 2013 to identify and partner with high‐quality SNFs. This study details the method by which PHS selected SNFs using minimum criteria based on public scores and secondary criteria based on self‐reported measures, describes the characteristics of selected and nonselected SNFs, and reports SNF satisfaction with the collaborative. The selected SNFs (n = 47) had significantly higher CMS Five‐Star scores than the nonselected SNFs (n = 93) (4.6 vs 3.2, < .001) and were more likely than nonselected SNFs that met the minimum criteria (n = 35) to have more than 5 days of clinical coverage (17.0% vs 2.9%, P = .02) and to have a physician see admitted individuals within 24 (38.3% vs 17.1%, P = .02) and 48 hours (93.6% vs 80.0%, P = .03). A survey sent to collaborative SNFs found high satisfaction with the process (average satisfaction, 4.6/5, with 1 = very dissatisfied and 5 = very satisfied, n = 19). Although the challenges of improving care in SNFs remain daunting, this approach can serve as a first step toward greater clinical collaboration between acute and postacute settings that will lead to better outcomes for frail older adults.  相似文献

The impact of age‐related differences in blood pressure (BP) components on new‐onset hypertension is not known. A follow‐up examination of 93 303 normotensive individuals (mean age 41.1 years) who underwent a health checkup in 2005 was conducted every year for 8 years. The primary end point was new‐onset hypertension (systolic BP [SBP]/diastolic BP [DBP] ≥140/90 mm Hg and/or the initiation of antihypertensive medications with self‐reported hypertension). During the mean 4.9 years of follow‐up, 14 590 subjects developed hypertension. The impact of DBP on the risk of developing hypertension compared with optimal BP (SBP <120 mm Hg and DBP <80 mm Hg) was significantly greater than that of SBP in subjects younger than 50 years (hazard ratios, 17.5 for isolated diastolic high‐normal vs 10.5 for isolated systolic high‐normal [P<.001]; 8.0 for isolated diastolic normal vs 4.1 for isolated systolic normal [P<.001]). Among the subjects 50 years and older, the corresponding effects of DBP and SBP were similar. Regarding the risk of new‐onset hypertension, high DBP is more important than SBP in younger adults (<50 years) with normal or high‐normal BP.  相似文献

Sofosbuvir‐based direct‐acting antiviral (DAA) therapy generally cures chronic hepatitis C (CHC) infections, however, the effects on the underlying liver disease and the potential rate of recovery are unclear. We aimed to investigate the effects of DAA therapy on liver inflammation, fibrosis, metabolic function and cognitive function and the time course in CHC patients with advanced liver disease. Seventy‐one CHC patients with advanced liver disease were studied before, during and one year after successful sofosbuvir‐based DAA therapy. Liver inflammation was assessed by plasma sCD163 and sMR levels (ELISA), fibrosis by liver stiffness (transient elastography), function by galactose elimination capacity (GEC) and cognitive performance by continuous reaction time (CRT). During DAA therapy, we observed a rapid sCD163 decline from baseline to end of treatment (6.9 vs 3.8 mg/L, P < .0001), whereas the change in sMR was more subtle (0.37 vs 0.30 mg/L, P < .0001). Liver stiffness decreased by 20% at end of treatment (17.8 vs 14.3 kPa, P < .0001), together suggesting rapid resolution of liver inflammation. One year after treatment, liver stiffness decreased by an additional 15% (P < .0001), suggestive of fibrosis regression. The GEC improved at follow‐up (all: 1.74 vs 1.98 mmol/min), mainly at 12 weeks post‐treatment, both in patients with cirrhosis (n = 56) and those with advanced liver fibrosis (n = 15) (P < .001). The CRT improved at one‐year follow‐up (1.86 vs 2.09, P = .04). In conclusion, successful DAA therapy of CHC proves beneficial in advanced liver disease, with an initial rapid resolution of liver inflammation and a subsequent gradual but steady improvement in liver fibrosis, metabolic liver function and reaction time.  相似文献

The effect of baseline resistance‐associated substitutions on the sustained virologic response at 12 weeks in chronic hepatitis C subjects has drawn considerable attention. However, it has been reported that the relationship between such substitutions and sustained virologic response at 12 weeks in chronic hepatitis C subjects is variable in different treatments. This meta‐analysis was performed to evaluate this relationship in subjects treated with glecaprevir/pibrentasvir. A systematic literature search up to May 2020 was done, and 17 studies were identified with 6501 chronic hepatitis C subjects. They were reporting relationships between baseline resistance‐associated substitutions and sustained virologic response at 12 weeks in chronic hepatitis C subjects treated with glecaprevir/pibrentasvir. The odds ratio (OR) with 95% confidence intervals (CIs) was calculated to evaluate the prognostic role of baseline resistance‐associated substitutions on the sustained virologic response at 12 weeks in chronic hepatitis C subjects treated with glecaprevir/pibrentasvir using the dichotomous method with a random or fixed‐effect model. Lower sustained virologic response at 12 weeks post‐treatment in chronic hepatitis C subjects was significantly related to baseline resistance‐associated substitutions in overall genotypes (OR, 0.03; 95% CI, 0.15‐0.61, P < .001), baseline NS5a resistance‐associated substitutions in genotype‐1 (OR, 0.16; 95% CI, 0.04‐0.57, P = .005), baseline resistance‐associated substitutions in genotype‐3 (OR, 0.14; 95% CI, 0.05‐0.38, P < .001), and baseline NS5a resistance‐associated substitutions in genotype‐3 (OR, 0.21; 95% CI, 0.09‐0.49, P < .001). Sustained virologic response at 12 weeks in chronic hepatitis C subjects was not significantly related to the baseline NS5a resistance‐associated substitutions (OR, 0.61; 95% CI, 0.17‐2.22, P = .45), and baseline resistance‐associated substitutions in genotype‐1 (OR, 0.35; 95% CI, 0.12‐1.088, P = .07). In conclusion, the impact of baseline resistance‐associated substitutions on the sustained virologic response at 12 weeks in chronic hepatitis C subjects treated with glecaprevir/pibrentasvir may have a great prognostic effect, especially in genotype‐3 as a tool to improve treatment prediction. Chronic hepatitis C subjects with baseline resistance‐associated substitutions may have an independent risk relationship with poor treatment outcomes. This relationship forces us to recommend testing prior to treatment selection to avoid any possible treatment failure.  相似文献

We compared the outcomes of multiple myeloma (MM) patients aged 21–40 and 41–60 years in the novel agent era. This case‐control study included 1089 patients between 2000 and 2015. Cases and controls were matched for sex, International Staging System (ISS) stage and institution. There were 173 patients in the younger group and 916 patients in the older group. Younger patients presented with a higher incidence of lytic lesions (82% vs. 72%; P = 0·04) and high‐risk cytogenetic abnormalities (83% vs. 68%; P = 0·007), but lower rate of elevated lactate dehydrogenase (21% vs. 44%; P < 0·001). Five‐ and 10‐year overall survival (OS) in younger versus older patients was 83% vs. 67% and 56% vs. 39%, respectively (P < 0·001). Similar results were seen when studying the subset of 780 patients who underwent autologous transplantation. Younger patients with ISS stage 1 had a better OS than older patients (P < 0·001). There was no survival difference between younger and older patients with ISS stage 2 or 3. Younger MM patients, aged 21–40 years, treated in the era of novel agents have a better OS than their counterparts aged 41–60 years, but the survival advantage observed in younger patients was lost in more advanced stages of MM.  相似文献

HIV co‐infection has been suggested to play a deleterious role on the pathogenesis of liver fibrosis among vertically HCV‐infected children. The aim of this study was to describe the longitudinal evolution of vertically acquired HIV/HCV co‐infection in youths, in comparison with HCV infection alone. This was a retrospective, multicentre study including vertically HIV/HCV–co‐infected patients and age‐ and sex‐matched vertically HCV–mono‐infected patients. Progression to advanced liver fibrosis, defined as F3 or more by elastography or METAVIR biopsy staging, and response to treatment were compared by means of univariate and multivariate regression analyses and Cox regression models. Sixty‐seven co‐infected patients were compared with 67 matched HCV–mono‐infected patients. No progression to advanced liver disease was observed during the first decade. At a median age of 20.0 [19.0, 22.0] years, 26.7% co‐infected vs 20% mono‐infected had progressed to advanced fibrosis (P = .617). Peg‐IFN/RBV for HCV treatment was given to 37.9% vs 86.6% (P‐value < .001). At treatment initiation, co‐infected patients were older (16.9 ± 4.1 vs 11.7 ± 4.5 years, P < .001), and 47.1% vs 7.1% showed advanced fibrosis (P < .003), with no differences in hard‐to‐treat genotype distribution. Sustained viral response was comparable between groups (43.5% vs 44.0%, P = .122). In vertically HIV/HCV–co‐infected patients, the progression to liver fibrosis was rare during childhood. At the end of adolescence, over 25% of patients displayed advanced liver disease. Response to Peg‐IFN/RBV was poor and comparable in both groups, supporting the need for fast access to early treatment with direct‐acting antivirals against HCV for vertically co‐infected patients.  相似文献

Measures of arterial stiffness are indicators for cardiovascular health and predictors of cardiovascular events. Arterial stiffness is responsive to acute physiologic stressors such as exercise. However, the acute effects of intensive exercise and recovery on arterial stiffness are controversial. Thirty‐seven healthy middle‐ and long‐distance runners (33 men, mean age 26.5±6.6 years) underwent evaluation of their cardiovascular stiffness at rest, after a 15‐minute warm‐up, immediately after vigorous running 3 km at the pace of their 10‐km personal best, and finally 30 minutes after terminating their workout. Peripheral and central systolic blood pressure, as well as augmentation index and pulse wave velocity (PWV), increased during exercise in comparison to baseline (P<.001, general linear model). Thirty minutes after terminating the workout, a drop in peripheral blood pressure (P<.001), central blood pressure (P<.001), and PWV (P=.001) below baseline was observed. Therefore, the authors found that exercise of either moderate or vigorous intensity causes a temporary increase in arterial stiffness in middle‐ and long‐distance runners.  相似文献

There is a lack of contemporary prospective data examining the adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) and Stanford V (SV; doxorubicin, vinblastine, mechlorethamine, vincristine, bleomycin, etoposide, prednisone) regimens in older Hodgkin lymphoma (HL) patients. Forty‐four advanced‐stage, older HL patients (aged ≥60 years) were treated on the randomized study, E2496. Toxicities were mostly similar between chemotherapy regimens, although 24% of older patients developed bleomycin lung toxicity (BLT), which occurred mainly with ABVD (91%). Further, the BLT‐related mortality rate was 18%. The overall treatment‐related mortality for older HL patients was 9% vs. 0·3% for patients aged <60 years (P < 0·001). Among older patients, there were no survival differences between ABVD and SV. According to age, outcomes were significantly inferior for older versus younger patients (5‐year failure‐free survival: 48% vs. 74%, respectively, P = 0·002; 5‐year overall survival: 58% and 90%, respectively, P < 0·0001), although time‐to‐progression (TTP) was not significantly different (5‐year TTP: 68% vs. 78%, respectively, P = 0·37). Furthermore, considering progression and death without progression as competing risks, the risk of progression was not different between older and younger HL patients (5 years: 30% and 23%, respectively, P = 0·30); however, the incidence of death without progression was significantly increased for older HL patients (22% vs. 9%, respectively, P < 0·0001). Altogether, the marked HL age‐dependent survival differences appeared attributable primarily to non‐HL events.  相似文献

Nucleos(t)ide analogues (NAs) have been shown to decrease the risk of hepatocellular carcinoma (HCC) recurrence. This study evaluated whether high‐potency NAs (entecavir and tenofovir disoproxil fumarate [TDF]) reduce the risk of tumour recurrence more potently than low‐potency NAs after curative treatment of hepatitis B virus (HBV)‐related HCC. This study included 607 consecutive HBV‐related HCC patients treated with surgical resection or radiofrequency ablation. The patients were categorized into three groups according to antiviral treatment: group A (no antiviral; n = 261), group B (low‐potency NA; n = 90) and group C (high‐potency NA; n = 256). The primary end‐point was recurrence‐free survival (RFS). During the duration of follow‐up, the median RFS was 29.4, 25.1, and 88.2 months in groups A, B and C, respectively (P < .001, log‐rank test). The multivariate Cox analysis indicated that group C had a significantly longer RFS than both group A (adjusted hazard ratio [HR] = 0.39, P < .001) and group B (adjusted HR = 0.47, P < .001). When baseline characteristics were balanced using inverse probability weighting, group C still had a significantly longer RFS than group A (adjusted HR = 0.46, P < .001) and group B (adjusted HR = 0.59, P = .007). Group C had significantly lower risk of viral breakthrough than group B (HR = 0.19, P < .001). Viral breakthrough was an independent risk factor for shorter RFS among groups B and C (adjusted HR = 2.03, P = .007, time‐dependent Cox analysis). Antiviral agents with high genetic barrier to resistance (entecavir and TDF) reduced the risk of HCC recurrence compared with other antivirals and no antiviral treatment, especially in patients with high baseline viral load.  相似文献

Hypertension has been associated with atherosclerosis and cardiovascular disease. Carotid intima media thickness is increased in hypertensive patients. But, the correlation between carotid intima media thickness and antihypertensive agents is still uncertain. Therefore, we investigated carotid intima media thickness based on types of antihypertensive agents. 1809 patients were enrolled in this study and it showed that 1079 hypertensive patients had thicker carotid intima media thickness than non‐hypertensive patients, with carotid intima media thicknesses of (0.72 ± 17 mm vs 0.64 ± 15 mm, P < .001), (0.31 ± 0.07 mm vs 0.30 ± 0.06 mm, P < .001), and (0.41 ± 0.13 mm vs 0.35 ± 0.12 mm, P < .001). Additionally, hypertensive patients on beta‐blockers also had thicker carotid intima media thickness than the non‐beta‐blocker group, with carotid intima media thicknesses of (0.74 ± 0.18 mm vs 0.71 ± 0.16 mm, P = .018), (0.33 ± 0.09 mm vs 0.31 ± 0.07 mm, P = .029), and (0.43 ± 0.13 mm vs 0.40 ± 0.13 mm, P = .035). Multivariate analysis showed that carotid intima thickness was only correlated with beta‐blockers (odds ratio = 2.489, confidence interval = 1.183‐5.239, P = .016); however, this study showed that beta‐blocker could be associated with increased carotid wall thickness as well.  相似文献

Introduction

Central venous access devices (CVADs) facilitate repeated or urgent treatments for paediatric haemophilia patients, but are associated with complications. This study examined the burden of illness, healthcare utilization and costs for CVADs in a real‐world hospital setting.

Materials and Methods

This study included haemophilia patients ages ≤18 years with discharges during 2006‐2014 in the US Premier Healthcare Database. Haemophilia was identified using ICD‐9 diagnosis codes and CVAD exposure using billing information. After matching haemophilia patients with and without CVADs on demographic and clinical characteristics, we compared infection, thrombosis, length of stay (LOS), inflation‐adjusted hospital cost (2014 $USD) and readmission outcomes using generalized estimating equation models adjusted for hospital teaching status.

Results

Among 4793 paediatric haemophilia patients treated at one of 548 hospitals, a total of 197 patients were identified with CVAD exposure. The matched sample included 310 haemophilia patients (155 CVAD and 155 non‐CVAD). CVAD cases had greater frequencies of all‐cause infections (29% vs 17%, P = .01) and thrombosis (6% vs 1%, P = .06), longer adjusted mean LOS (9.5 vs 4.7 days, P = .002), higher adjusted mean inpatient total hospitalization costs ($47200 vs $25389, P = .02) as well as more inpatient and outpatient visits at 30‐, 60‐ and 90‐days (P < .05 for all differences) compared with non‐CVAD patients.

Conclusion

Paediatric haemophilia patients with CVADs experienced greater infection rates, healthcare utilization and higher hospitalization costs compared with non‐CVAD patients. The results of this study may inform further research efforts to understand the costs and benefits of novel treatment alternatives for young haemophilia patients requiring CVADs.  相似文献

Objectives

The aim of this study was to evaluate the hemodynamic performance of a sutureless bioprosthesis under high workload at mid‐term follow‐up.

Methods

Thirty‐two patients who underwent isolated aortic valve replacement with a Perceval sutureless bioprosthesis with a minimum follow‐up of 1 year were enrolled in this study. S size prosthesis was deployed in 10 patients (31.3%), M size in 9 (28.1%), L size in 8 (25%) and XL size in 5 (15.6%). Effective orifice area (EOA), EOA index (EOAi), and transvalvular gradients were assessed at rest and during dobutamine stress echocardiography (DSE) a median of 19.5 months after surgery.

Results

Dobutamine stress echocardiography (DSE) significantly increased heart rate, stroke volume, ejection fraction, and transvalvular gradients (peak gradient, 24.0 ± 7.6 vs 38.7 ± 13.6 mm Hg, P < .001; mean gradient, 12.6 ± 4.2 vs 19.8 ± 8.3, P < .001). When compared to baseline, estimated valve areas significantly increased at follow‐up (EOA, 1.48 ± 0.46 vs 2.06 ± 0.67, P < .001; EOAi, 0.84 ± 0.26 vs 1.17 ± 0.37, P < .001). Mean percentage increase in EOAi was 40.3% ± 28.0%. S size prostheses had the highest increase in EOA1, but the difference was not significant (S 46.0% ± 27.5% vs M 45.4% ± 34.5% vs L 32.7% ± 26.4% vs XL 32.1% ± 20.5%, P = .66). Severe patient‐prosthesis mismatch (EOAi ≤ 0.65 cm2/m2) was present at rest in 8 patients (25%), but only in one patient (3.1%) during DSE.

Conclusions

The Perceval sutureless bioprosthesis demonstrated good hemodynamics at rest and under high workload. The significant increase in EOAi during DSE suggests the potential advantages of Perceval sutureless bioprostheses in case of small aortic annulus or when patient‐prosthesis mismatch is anticipated.  相似文献

The nucleotide substitution G1896A on the precore (pc) region has been implicated in virological and serological responses during treatment in hepatitis B virus (HBV)‐infected patients. Whether this mutation affects the therapeutic course of HIV‐HBV co‐infected patients, especially from Western Africa, is unknown. In this prospective cohort study, 86 antiretroviral (ARV)‐naïve HIV‐HBV co‐infected patients from Côte d'Ivoire, initiating ARV‐treatment containing lamivudine (n = 53) or tenofovir (n = 33), had available baseline pc sequences. Association of the pcG1896A mutation with time to undetectable HBV‐DNA, hepatitis B “e” antigen (HBeAg) seroclearance (in HBeAg‐positive patients), and hepatitis B surface antigen (HBsAg) seroclearance was evaluated using Cox proportional hazards regression. At ARV‐initiation, median HBV‐DNA was 6.04 log10 copies/mL (IQR = 3.70‐7.93) with 97.7% harbouring HBV genotype E. Baseline pcG1896A mutation was identified in 51 (59.3%) patients, who were more commonly HBeAg‐negative (< .001) and had basal core promotor A1762T/G1764A mutations (< .001). Patients were followed for a median 36 months (IQR = 24‐36). Cumulative proportion of undetectable HBV‐DNA was significantly higher in patients with baseline mutation (pcG1896A = 86.6% vs no pcG1896A = 66.9%, = .04), but not after adjusting for baseline HBV‐DNA levels and anti‐HBV agent (= .2). No difference in cumulative proportion of HBeAg seroclearance was observed between mutation groups (pcG1896A = 57.1% vs no pcG1896A = 54.3%, = .7). Significantly higher cumulative proportion of HBsAg seroclearance was observed in patients without this mutation (pcG1896A = 0% vs no pcG1896A = 36.9%, < .001), even after adjusting for baseline HBsAg quantification and anti‐HBV agent (< .001). In conclusion, lacking the pcG1896A mutation before ARV initiation appeared to increase HBsAg seroclearance rates during treatment. The therapeutic implications of this mutation need further exploration in this setting.  相似文献

Hepatitis B surface antigen (HBsAg) reduction during nucleoside/nucleotide analogue (NA) therapy is slow and an alternative strategy for patients receiving ongoing NA to facilitate HBsAg reduction is required. We investigated whether switching to pegylated interferon (PEG‐IFN) after long‐term NA administration enhances HBsAg reduction. Forty‐nine patients who switched from long‐term NA to 48 weeks of PEG‐IFN alfa‐2a were studied. The mean duration of previous NA was 48 months (sequential group). A total of 147 patients who continued NA and matched for baseline characteristics were analysed for comparison (NA continuation group). The treatment response was defined as HBsAg reduction ≥1.0 logIU/mL at the end of PEG‐IFN. HBsAg reduction at week 48 was 0.81±1.1 logIU/mL in the sequential group, which was significantly higher than that in the NA continuation group (0.11±0.3 logIU/mL, P < .001). The treatment response was achieved in 29% and 2% of the sequential group and NA continuation group (P < .001), and the odds ratio of sequential therapy for the treatment response was 19 compared with the NA continuation (P < .001). In patients tested positive for hepatitis B e antigen (HBeAg), HBeAg seroconversion was higher in the sequential group (44% vs 8%, P < .001). In HBeAg‐negative patients, only patients in the sequential group achieved HBsAg loss. No patient needed to resume NA administration because of HBV DNA increase accompanied by alanine aminotransferase flares. In summary, sequential therapy with PEG‐IFN after long‐term NA enhances the reduction of HBsAg and may represent a treatment option to promote HBsAg loss.  相似文献
