Temporal changes in breast cancer incidence in South Asian women

BackgroundBreast cancer in the UK resident population of South Asian ethnicity has been lower than that in indigenous women. Leicester has a large South Asian population and a breast cancer unit with comprehensive data on diagnosed cancers. This study analysed the annual incidence of new breast cancer diagnoses in females from 1998 to 2009 to determine any changes in recent years.MethodsEthnicity was known in over 98% of cases. Population denominators were based on published figures for 2001 and 2011, projected back to 1998. Age-adjusted directly standardised incidence rates were determined by ethnicity and broken down by invasive status and screening classification. Incidence rates were analysed using logistic regression in order to identify statistically significant effects of age, ethnicity, deprivation and year of diagnosis. Interactions with invasive status and screening classification were also investigated.ResultsAt the start of the study period South Asian incidence was estimated to be 45% of that of the white population (p < 0.001); by the end of the period the difference was still significant (p = 0.022) but smaller, at 17%.ConclusionSouth Asians should no longer be considered at low risk of breast cancer.     

Inequality in Diabetes-Related Hospital Admissions in England by Socioeconomic Deprivation and Ethnicity: Facility-Based Cross-Sectional Analysis

ObjectiveTo investigate the effect of social deprivation and ethnicity on inpatient admissions due to diabetes in England.DesignFacility-based cross-sectional analysis.SettingNational Health Service (NHS) trusts in England reporting inpatient admissions with better than 80% data reporting quality from 2010–2011 (355 facilities).ParticipantsNon-obstetric patients over 16 years old in all NHS facilities in England. The sample size after exclusions was 5,147,859 all-cause admissions.ResultsThere were 445,504 diabetes-related hospital admissions in England in 2010, giving a directly (age-sex) standardized rate of 1049.0 per 100,000 population (95% confidence interval (CI): 1046.0–1052.1). The relative risk of inpatient admission in the most deprived quintile was 2.08 times higher than that of the least deprived quintile (95% CI: 2.02–2.14), and the effect of deprivation varied across ethnicities. About 30.1% of patients admitted due to diabetes were readmitted at least once due to diabetes. South Asians showed 2.62 times (95% CI: 2.51 – 2.74) higher admission risk. Readmission risk increased with IMD among white British but not other ethnicities. South Asians showed slightly lower risk of readmission than white British (0.86, 95% CI: 0.80 – 0.94).ConclusionsMore deprived areas had higher rates of inpatient admissions and readmissions due to diabetes. South Asian British showed higher admission risk and lower readmission risk than white British. However, there was almost no difference by ethnicity in readmission due to diabetes. Higher rates of admission among deprived people may not necessarily reflect higher prevalence, but higher admission rates in south Asian British may be explained by their higher prevalence because their lower readmission risk suggests no inequality in primary care to prevent readmission. Better interventions in poorer areas, are needed to reduce these inequalities.     

Influences on hospital admission for asthma in south Asian and white adults: qualitative interview study

ObjectiveTo explore reasons for increased risk of hospital admission among south Asian patients with asthma.DesignQualitative interview study using modified critical incident technique and framework analysis.SettingNewham, east London, a deprived area with a large mixed south Asian population.Participants58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse.ResultsSouth Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission.ConclusionsThe different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in exacerbations may reduce hospital admissions. Development of more sophisticated asthma strategies by practices with better access and partnerships with patients may also achieve this.

What is already known on this topic

South Asian patients with asthma are at increased risk of hospital admission with asthma compared with white patientsNo consistent differences in severity or prevalence of asthma, prescribed drugs, or asthma education have been described, and interventions to reduce admission rates in Asian patients have met with variable success

What this study adds

Compared with white patients, south Asian patients admitted to hospital with asthma had less confidence to control asthma, were unfamiliar with the concept of preventive medication, and had less confidence in their general practitionersSouth Asian patients managed asthma attacks through family advocacy and without systematic changes in prophylaxis and without systemic corticosteroidsPatients reporting difficulty in accessing primary care during attacks were often south Asian     

The High Cost of HIV-Positive Inpatient Care at an Urban Hospital in Johannesburg,South Africa

Background

While most HIV care is provided on an outpatient basis, hospitals continue to treat serious HIV-related admissions, which is relatively resource-intensive and expensive. This study reports the primary reasons for HIV-related admission at a regional, urban hospital in Johannesburg, South Africa and estimates the associated lengths of stay and costs.

Methods and Findings

A retrospective cohort study of adult, medical admissions was conducted. Each admission was assigned a reason for admission and an outcome. The length of stay was calculated for all patients (N = 1,041) and for HIV-positive patients (n = 469), actual utilization and associated costs were also estimated. Just under half were known to be HIV-positive admissions. Deaths and transfers were proportionately higher amongst HIV-positive admissions compared to HIV-negative and unknown. The three most common reasons for admission were tuberculosis and other mycobacterial infections (18%, n = 187), cardiovascular disorders (12%, n = 127) and bacterial infections (12%, n = 121). The study sample utilized a total of 7,733 bed days of those, 55% (4,259/7,733) were for HIV-positive patients. The average cost per admission amongst confirmed HIV-positive patients, which was an average of 9.3 days in length, was $1,783 (United States Dollars).

Conclusions

Even in the era of large-scale antiretroviral treatment, inpatient facilities in South Africa shoulder a significant HIV burden. The majority of this burden is related to patients not on ART (298/469, 64%), and accounts for more than half of all inpatient resources. Reducing the costs of inpatient care is thus another important benefit of expanding access to ART, promoting earlier ART initiation, and achieving rates of ART retention and adherence.     

Short-Term Outcomes of Hip Fractures in Patients Aged 90 Years Old and Over Receiving Surgical Intervention

BackgroundThe knowledge about short-term outcomes of nonagenarians undergoing surgery for hip fracture in Asian is limited.MethodsThe patients with hip fractures who underwent hip hemiarthroplasty and open reduction with internal fixation (ORIF) for management during the period from 2008 to 2012 were identified and their medical record was retrospectively reviewed.ResultsDuring the study period, a total of 101 patients underwent surgery for management of hip fractures, and the age of patients ranged from 90 to 96 years. The sites of hip fracture were intertrochanteric (n = 57, 56.4%) and the neck of the femur (n = 44, 43.6%). Most of the patients had American Society of Anesthesiologists scores of 3(n = 55) or 4 (in 44 patients). 80.2% (n = 81) underwent the operation within one day after admission; however, there were 13 patients (12.9%) that underwent surgery 48 or more hours later. ORIF and hemiarthroplasty were performed for 63 (62.4%) and 38 (37.6%) patients, respectively. Overall, the 30-day and 1-year mortality rates were 9.9% (10/101) and 17.3% (13/75), respectively. Multivariate analysis showed that the 30-day mortality was significantly associated only with end-stage renal disease (ESRD) (Odds ratio, 11.13, 95% confidence interval, 1.275–97.881, P = .029).ConclusionsThe short-term outcome of surgical management for Asian nonagenarians with hip fractures is favorable in selected patients.     

Trends in the incidence and outcomes of heart failure in Ontario, Canada: 1997 to 2007

Background:

Heart failure is a leading cause of admission to hospital, but whether the incidence of heart failure is increasing or decreasing is uncertain. We examined temporal trends in the incidence and outcomes of heart failure in Ontario, Canada.

Methods:

Using population-based administrative databases of hospital discharge abstracts and physician health insurance claims, we identified 419 551 incident cases of heart failure in Ontario between Apr. 1, 1997, and Mar. 31, 2008. All patients were classified as either inpatients or outpatients based on the patient’s location at the time of the initial diagnosis. We tracked subsequent outcomes through linked administrative databases.

Results:

The age- and sex-standardized incidence of heart failure decreased 32.7% from 454.7 per 100 000 people in 1997 to 306.1 per 100 000 people in 2007 (p < 0.001). A comparable decrease in incidence occurred in both inpatient and outpatient settings. The greatest relative decrease occurred in patients aged 85 and over. Over the study period, 1-year risk-adjusted mortality decreased from 17.7% in 1997 to 16.2% in 2007 (p = 0.02) for outpatients, with a nonsignificant decrease from 35.7% in 1997 to 33.8% in 2007 (p = 0.1) for inpatients.

Interpretation:

The incidence of heart failure decreased substantially during the study period. Nevertheless, the prognosis for patients with heart failure remains poor and is associated with high mortality.Heart failure is a leading cause of admission to hospital and is associated with a poor long-term prognosis. In 1996, it was projected that the number of incident hospital admissions for heart failure in Canada would more than double by 2025 because of the aging population and increasing numbers of myocardial infarction survivors.¹ By 2000, patients with heart failure accounted for the second highest number of hospital days in Canada, and the estimated 1-year case-fatality rate, after the first hospital admission, exceeded 35%.^2,3 However, some recent studies suggest that admission and mortality rates for heart failure may actually be falling. It is unclear whether these changes represent lower rates of new incident cases, fewer readmissions, a shift to more outpatient care or improved survival.^4,5We sought to examine temporal trends in the incidence and outcomes of heart failure in Ontario, Canada, in both inpatient and outpatient settings to assess the progress made in reducing the population burden of heart failure and to gain insight into the effectiveness of current preventive and therapeutic strategies.     

Comparison of case fatality in south Asian and white patients after acute myocardial infarction: observational study.

OBJECTIVE--To compare mortality in south Asian (Indian, Pakistani, and Bangladeshi) and white patients in the six months after hospital admission for acute myocardial infarction. DESIGN--Observational study. SETTING--District general hospital in east London. PATIENTS--149 south Asian and 313 white patients aged < 65 years admitted to the coronary care unit with acute myocardial infarction from 1 December 1988 to 31 December 1992. MAIN OUTCOME MEASURE--All cause mortality in the first six months after myocardial infarction. RESULTS--The admission rate in the south Asians was estimated to be 2.04 times that in the white patients. Most aspects of treatment were similar in the two groups, except that a higher proportion of the south Asians received thrombolytic drugs (81.2% v 73.8%). After adjustment for age, sex, previous myocardial infarction, and treatment with thrombolysis or aspirin, or both, the south Asians had a poorer survival over the six months from myocardial infarction (hazard ratio 2.02 (95% confidence interval 1.14 to 3.56), P = 0.018), but a substantially higher proportion were diabetic (38% v 11%, P < 0.001), and additional adjustment for diabetes removed much of their excess risk (adjusted hazard ratio 1.26 (0.68 to 2.33), P = 0.47). CONCLUSION--South Asian patients had a higher risk of admission with myocardial infarction and a higher risk of death over the ensuing six months than the white patients. The higher case fatality among the south Asians, largely attributable to diabetes, may contribute to the increased risk of death from coronary heart disease in south Asians living in Britain.     

Early evidence of ethnic differences in cardiovascular risk: cross sectional comparison of British South Asian and white children

ObjectivesTo examine whether British South Asian children differ in insulin resistance, adiposity, and cardiovascular risk profile from white children.DesignCross sectional study.SettingPrimary schools in 10 British towns.ParticipantsBritish children aged 8 to 11 years (227 South Asian and 3415 white); 73 South Asian and 1287 white children aged 10 and 11 years provided blood samples (half fasting, half after glucose load).ResultsMean ponderal index was lower in South Asian children than in white children (mean difference −0.43 kg/m³, 95% confidence interval −0.13 kg/m³ to −0.73 kg/m³). Mean waist circumferences and waist:hip ratios were similar. Mean insulin concentrations were higher in South Asian children (percentage difference was 53%, 14% to 106%, after fasting and 54%, 19% to 99%, after glucose load), though glucose concentrations were similar. Mean heart rate and triglyceride and fibrinogen concentrations were higher among South Asian children; serum total, low density lipoprotein, and high density lipoprotein cholesterol concentrations were similar in the two groups. Differences in insulin concentrations remained after adjustment for adiposity and other potential confounders. However, the relations between adiposity and insulin concentrations (particularly fasting insulin) were much stronger among South Asian children than among white children.ConclusionsThe tendency to insulin resistance observed in British South Asian adults is apparent in children, in whom it may reflect an increased sensitivity to adiposity. Action to prevent non-insulin dependent diabetes in South Asian adults may need to begin during childhood.

What is already known on this topic

Compared with white people British South Asians are at increased risk of coronary heart disease, stroke, and non-insulin dependent diabetesThere is evidence that these conditions originate in early life

What this study adds

British South Asian children show higher average levels of insulin and insulin resistance than white childrenThese ethnic differences in insulin resistance in childhood are not associated with corresponding differences in adiposity, particularly central adiposityInsulin metabolism seems to be more sensitive to a given degree of adiposity among the South Asian children compared with white childrenThe prevention of insulin resistance and its consequences may need to begin during childhood, particularly in South Asians     

The eVALuate study: two parallel randomised trials,one comparing laparoscopic with abdominal hysterectomy,the other comparing laparoscopic with vaginal hysterectomy

Objective To compare the effects of laparoscopic hysterectomy and abdominal hysterectomy in the abdominal trial, and laparoscopic hysterectomy and vaginal hysterectomy in the vaginal trial.Design Two parallel, multicentre, randomised trials.Setting 28 UK centres and two South African centres.Participants 1380 women were recruited; 1346 had surgery; 937 were followed up at one year.Primary outcome Rate of major complications.Results In the abdominal trial laparoscopic hysterectomy was associated with a higher rate of major complications than abdominal hysterectomy (11.1% v 6.2%, P = 0.02; difference 4.9%, 95% confidence interval 0.9% to 9.1%) and the number needed to treat to harm was 20. Laparoscopic hysterectomy also took longer to perform (84 minutes v 50 minutes) but was less painful (visual analogue scale 3.51 v 3.88, P = 0.01) and resulted in a shorter stay in hospital after the operation (3 days v 4 days). Six weeks after the operation, laparoscopic hysterectomy was associated with less pain and better quality of life than abdominal hysterectomy (SF-12, body image scale, and sexual activity questionnaires).In the vaginal trial we found no evidence of a difference in major complication rates between laparoscopic hysterectomy and vaginal hysterectomy (9.8% v 9.5%, P = 0.92; difference 0.3%, -5.2% to 5.8%), and the number needed to treat to harm was 333. We found no evidence of other differences between laparoscopic hysterectomy and vaginal hysterectomy except that laparoscopic hysterectomy took longer to perform (72 minutes v 39 minutes) and was associated with a higher rate of detecting unexpected pathology (16.4% v 4.8%, P = < 0.01). However, this trial was underpowered.Conclusions Laparoscopic hysterectomy was associated with a significantly higher rate of major complications than abdominal hysterectomy. It also took longer to perform but was associated with less pain, quicker recovery, and better short term quality of life. The trial comparing vaginal hysterectomy with laparoscopic hysterectomy was underpowered and is inconclusive on the rate of major complications; however, vaginal hysterectomy took less time.     

Ethnic differences in guideline-indicated statin initiation for people with type 2 diabetes in UK primary care, 2006–2019: A cohort study

BackgroundType 2 diabetes is 2–3 times more prevalent in people of South Asian and African/African Caribbean ethnicity than people of European ethnicity living in the UK. The former 2 groups also experience excess atherosclerotic cardiovascular disease (ASCVD) complications of diabetes. We aimed to study ethnic differences in statin initiation, a cornerstone of ASCVD primary prevention, for people with type 2 diabetes.Methods and findingsObservational cohort study of UK primary care records, from 1 January 2006 to 30 June 2019. Data were studied from 27,511 (88%) people of European ethnicity, 2,386 (8%) people of South Asian ethnicity, and 1,142 (4%) people of African/African Caribbean ethnicity with incident type 2 diabetes, no previous ASCVD, and statin use indicated by guidelines. Statin initiation rates were contrasted by ethnicity, and the number of ASCVD events that could be prevented by equalising prescribing rates across ethnic groups was estimated. Median time to statin initiation was 79, 109, and 84 days for people of European, South Asian, and African/African Caribbean ethnicity, respectively. People of African/African Caribbean ethnicity were a third less likely to receive guideline-indicated statins than European people (n/N [%]: 605/1,142 [53%] and 18,803/27,511 [68%], respectively; age- and gender-adjusted HR 0.67 [95% CI 0.60 to 0.76], p < 0.001). The HR attenuated marginally in a model adjusting for total cholesterol/high-density lipoprotein cholesterol ratio (0.77 [95% CI 0.69 to 0.85], p < 0.001), with no further diminution when deprivation, ASCVD risk factors, comorbidity, polypharmacy, and healthcare usage were accounted for (fully adjusted HR 0.76 [95% CI 0.68, 0.85], p < 0.001). People of South Asian ethnicity were 10% less likely to receive a statin than European people (1,489/2,386 [62%] and 18,803/27,511 [68%], respectively; fully adjusted HR 0.91 [95% CI 0.85 to 0.98], p = 0.008, adjusting for all covariates). We estimated that up to 12,600 ASCVD events could be prevented over the lifetimes of people currently affected by type 2 diabetes in the UK by equalising statin prescribing across ethnic groups. Limitations included incompleteness of recording of routinely collected data.ConclusionsIn this study we observed that people of African/African Caribbean ethnicity with type 2 diabetes were substantially less likely, and people of South Asian ethnicity marginally less likely, to receive guideline-indicated statins than people of European ethnicity, even after accounting for sociodemographics, healthcare usage, ASCVD risk factors, and comorbidity. Underuse of statins in people of African/African Caribbean or South Asian ethnicity with type 2 diabetes is a missed opportunity to prevent cardiovascular events.

In a retrospective cohort study, Sophie Eastwood and colleagues investigate the association between ethnicity and statin initiation for people with type 2 diabetes in UK.     

Glucocorticoid-Induced Adrenal Insufficiency: A Study of the Incidence in Hospital Patients and A Review of Peri-Operative Management

Objective: Glucocorticoid (GC) pharmacotherapy is an effective treatment for a range of diseases, but exposure can suppress the hypothalamic-pituitary-adrenal axis, leading to glucocorticoid-induced adrenal insufficiency (GC-AI) in some patients. However, the incidence of diagnosed GC-AI and the associated health burden, including the incidence of adrenal crises (ACs), are unknown. Although GC-AI treatment is based on well-established principles, there are no agreed protocols regarding the peri-operative management of exposed patients. The aims of this study were to assess the incidence of diagnosed GC-AI in hospital patients and review current approaches to peri-operative management of surgical patients with GC exposure.Methods: An analysis of hospital admission data concerning adult patients diagnosed with GC-AI and a review of published recommendations for peri-operative GC cover.Results: Between 2001 and 2013, admission with a diagnosis of GC-AI in New South Wales, Australia was rare (annual average of 22.5 admissions/year) and ACs were even more rare (n = 3). Almost two-thirds (64.4%, n = 188) of the patients with diagnosed GC-AI were aged between 50 and 79 years and 45.2% (n = 132) had a comorbid infection. The current approach to peri-operative management of patients with GC exposure appears to be influenced by both the absence of clear guidelines and historic practices. This results in the exposure of some patients to supraphysiologic doses of GCs during the peri-operative period.Conclusion: Hospital admission with a diagnosis of GC-AI (with or without an AC) is very rare. Clear guidelines on peri-operative GC cover are necessary to avoid overreplacement with supraphysiologic doses in susceptible patients.Abbreviations: AC = adrenal crisis; ACTH = adrenocorticotropic hormone; AI = adrenal insufficiency; CI = confidence interval; GC = glucocorticoid; GC-AI = glucocorticoid-induced adrenal insufficiency; HPA = hypothalamic-pituitary-adrenal; OR = odds ratio     

Do Ethnic Disparities Extend to Subspecialty Diabetes Care?

ObjectiveIt is unclear if disparities described in diabetes primary care extend to subspecialty diabetes care. This retrospective observational study examined disparities in diabetes outcomes in a subspecialty practice by assessing glycemic improvement in type 2 diabetes patients during the first year of enrollment.MethodsElectronic data were gathered on 3,945 subjects. The outcome was the proportion of white and minority (Asian, black, and Hispanic) subjects achieving a hemoglobin A1C (A1C) level of ≤7% after the first year of care. Logistic regression was used to identify factors associated with odds of achieving A1C ≤7%.ResultsMinority patients had greater diabetes duration, more social disadvantages and missed appointments, and worse control at presentation than whites. The proportion of patients reaching target A1C rose from 37 to 52% among white patients and from 28 to 40% among minority patients. Significant differences between whites and minorities in the rates of patients reaching A1C ≤7% were found only among those with higher initial A1C (iA1C) levels (32% vs. 20.9%; P = .002 in third iA1C quartile, and 28.2% vs. 17.9%; P = .0003 in fourth iA1C quartile). The interaction between race/ethnicity and the top two iA1C quartiles remained significant in the fully adjusted model.ConclusionReaching an A1C level of ≤7% depends strongly upon the glycemic level at initial presentation to specialty care, not race. However, minority patients with the highest baseline A1C levels do not improve to the same degree as white patients, and therefore should be targeted for more intensive diabetes care management.

Influence of genetic polymorphisms of cytokine genes in the outcome of HLA-matched allogeneic stem cell transplantation in a South East Asian population

Non-HLA gene polymorphisms have been shown to be associated with the risk of graft-versus-host disease (GVHD) and outcome of allogeneic haematopoietic stem cell transplantation (AHSCT). This study aims to investigate the role of IL6, TNFα, IL10, IL2 and IL12 gene polymorphisms in the outcome of AHSCT in a South East Asian population. A total of 67 patients and 59 donors who underwent HLA-identical matched sibling AHSCT were available for analysis. There was no significant association between the different cytokine genotypes of patients with the incidence and severity of acute GVHD. Patients with IL2 1661T allele and patients who received donor stem cells who had IL2 1661G allele appeared to have reduced incidence of cGVHD. Patients who received donor stem cells with IL12 11881C allele are found to be associated with better disease free survival. These results suggest a possible role of IL2 and IL12 gene polymorphisms in the outcome of AHSCT in a South East Asian population.     

Clinical Usefulness of Procalcitonin and C-Reactive Protein as Outcome Predictors in Critically Ill Patients with Severe Sepsis and Septic Shock

Sepsis is a major cause of mortality and morbidity in critically ill patients. Procalcitonin (PCT) and C-reactive protein (CRP) are the most frequently used biomarkers in sepsis. We investigated changes in PCT and CRP concentrations in critically ill patients with sepsis to determine which biochemical marker better predicts outcome. We retrospectively analyzed 171 episodes in 157 patients with severe sepsis and septic shock who were admitted to the Samsung Medical Center intensive care unit from March 2013 to February 2014. The primary endpoint was patient outcome within 7 days from ICU admission (treatment failure). The secondary endpoint was 28-day mortality. Severe sepsis was observed in 42 (25%) episodes from 41 patients, and septic shock was observed in 129 (75%) episodes from 120 patients. Fifty-five (32%) episodes from 42 patients had clinically-documented infection, and 116 (68%) episodes from 99 patients had microbiologically-documented infection. Initial peak PCT and CRP levels were not associated with treatment failure and 28-day mortality. However, PCT clearance (PCTc) and CRP (CRPc) clearance were significantly associated with treatment failure (p = 0.027 and p = 0.030, respectively) and marginally significant with 28-day mortality (p = 0.064 and p = 0.062, respectively). The AUC for prediction of treatment success was 0.71 (95% CI, 0.61–0.82) for PCTc and 0.71 (95% CI, 0.61–0.81) for CRPc. The AUC for survival prediction was 0.77 (95% CI, 0.66–0.88) for PCTc and 0.77 (95% CI, 0.67–0.88) for CRPc. Changes in PCT and CRP concentrations were associated with outcomes of critically ill septic patients. CRP may not be inferior to PCT in predicting outcome in these patients.     

Cardiac resynchronisation therapy: results from daily practice in Rijnstate Hospital, Arnhem

BackgroundCardiac resynchronisation therapy (CRT) is an effective treatment to improve the clinical outcome of selected patients with heart failure. Clinical trials have studied clinical outcome and reported clinical improvements, but clinical consequences and results in daily practice are less well known. We evaluated clinical outcome in all patients with CRT implantation in our centre. MethodsData of 119 consecutive patients who met the criteria for CRT implantation in Rijnstate Hospital, Arnhem in the period 28 November 2000 until 1 January 2006 were collected. We analysed implantation procedure, hospitalisation for heart failure or other causes, mortality and device-related events. ResultsIn total 119 patients (83 men, 36 women; mean age 69 years) were eligible for CRT. Before implantation they had received optimal pharmacological therapy. Implantation was successful in 97% of patients. Procedural-related complications were seen in eight patients. During follow-up, 22 patients (18.5%: 14 men, 8 women) died. Causes of death were heart failure (11 patients), sudden cardiac death (4 patients) and noncardiac death (7 patients). Hospitalisation occurred 81 times, of which 77 for cardiac reasons. In follow-up the estimated five-year cumulative survival was 70%. ConclusionThis retrospective study from a single centre showed a high procedural success rate, low prevalence of complications and low mortality in comparison to other studies. Despite better functional capacity, the hospitalisation rate due to heart failure was high. (Neth Heart J 2009;17:6-8.)     

Staging liver fibrosis after severe yellow fever with ultrasound elastography in Brazil: A six-month follow-up study

BackgroundYellow fever (YF) is a hemorrhagic disease caused by an arbovirus endemic in South America, with recent outbreaks in the last years. Severe cases exhibit fulminant hepatitis, but there are no studies regarding its late-term effects on liver parenchyma. Thus, the aim of this study was to determine the frequency and grade of liver fibrosis in patients who recovered from severe YF and to point out potential predictors of this outcome.Methodology/Principal findingsWe followed-up 18 patients who survived severe YF during a recent outbreak (January-April 2018) in Brazil using ultrasound (US) with shear-wave elastography (SWE) at 6 months after symptoms onset. No patient had previous history of liver disease.Median liver stiffness (LS) was 5.3 (4.6–6.4) kPa. 2 (11.1%) patients were classified as Metavir F2, 1 (8.3%) as F3 and 1 (8.3%) as F4; these two last patients had features of cardiogenic liver congestion on Doppler analysis. Age and cardiac failure were associated with increased LS (p = 0.036 and p = 0.024, respectively). SAPS-3 at ICU admission showed a tendency of association with significant fibrosis (≥ F2; p = 0.053). 7 patients used sofosbuvir in a research protocol, of which none showed liver fibrosis (p = 0.119).Conclusions/SignificanceWe found a low frequency of liver fibrosis in severe YF survivors. US with SWE may have a role in the follow up of patients of age and / or with comorbidities after hospital discharge in severe YF, a rare but reemergent disease.     

Haemodynamic patterns in ST-elevation myocardial infarction: incidence and correlates of elevated filling pressures

Objectives. We sought to study the incidence and clinical correlates of elevated filling pressures in ST-elevation myocardial infarction (STEMI) patients, without physical signs of heart failure and treated with primary coronary angioplasty. Background. Haemodynamic data, as measured with a Swan-Ganz catheter, are not routinely obtained in STEMI patients. At admission, low blood pressure, increased heart rate, sweating, increased respiration rate, rales, oedema, and a third heart sound are indicative of heart failure. Methods. All consecutive STEMI patients were monitored by a Swan-Ganz catheter and central venous pressure (CVP), pulmonary capillary wedge pressure (PCWP), pulmonary artery pressure (PAS) and cardiac index (CI) were measured. To investigate the clinical correlates of the haemodynamic status patients were classified according to previously defined haemodynamic criteria. Results. We studied 90 patients, aged 60.5±13.1 year, 76% were male. Mortality at 30 days was 2/90 (2.2%). Patients with impaired haemodynamics presented later and had larger myocardial infarct sizes. CVP, PCWP and PAS were above normal in 36 (40%) patients. Conclusion.

急性冠脉综合征患者急诊PCI术后心力衰竭的危险因素分析及护理干预

目的:探讨急性冠脉综合征(ACS)患者行急诊直接经皮冠状动脉介入治疗(PCI)后住院期间发生心力衰竭(HF)的危险因素分析及护理干预策略。方法:选取278例在我院接受急诊PCI手术患者为研究对象,按照术后住院期间是否出现心力衰竭分为两组:心力衰竭组(n=54例)和非心力衰竭组(n=224例),比较两组患者一般临床资料、实验室检查指标及相关治疗情况的差异,用Logistic回归分析探讨影响术后心力衰竭发生的危险因素,并制定相关护理策略。结果:278例老年患者中有54例PCI术后出现心力衰竭(发生率19.4%);两组患者在年龄、高血压、糖尿病、入院收缩压(SBP)、发病至PCI时间、入院血糖、入院NT-pro BNP、肌酸激酶同工酶(CK-MB)峰值、肌酐蛋白I(c Tn I)峰值、左室射血分数(LVEF)、左室舒张末内径(LVEDd)、术后TIMI血流、使用他汀类药物、β-受体阻滞剂方面存在统计学差异(P0.05);发病至PCI时间、高血压、入院时血糖、NT-pro BNP、c Tn I峰值是术后心力衰竭发生的独立危险因素(P0.05);而术后TIMI血流、使用β-受体阻滞剂治疗是保护性因素。结论:ACS患者行急诊PCI治疗后HF的发生受到多种因素的影响,应当积极制定相关护理干预策略以降低术后HF的发生率。     

The Impact of Health Behaviours on Incident Cardiovascular Disease in Europeans and South Asians – A Prospective Analysis in the UK SABRE Study

Background

There is consistent evidence on the impact of health behaviours on risk of cardiovascular disease (CVD) in European populations. As South Asians in the UK have an excess risk of CVD and coronary heart disease (CHD) compared to Europeans, we investigated whether a similar association between combined health behaviours and risk of CVD and CHD among this high-risk group exists, and estimated the population impact.

Methods and Findings

In a prospective cohort of 1090 Europeans and 1006 South Asians (40–69 y) without prevalent CVD at baseline (1988–1990), followed up for 21 years to 2011, there were 601 incident CVD events [Europeans n = 255; South Asians n = 346] of which 520 were CHD events [n = 207 and 313 respectively]. Participants scored between 0 to 4 points for a composite score including four baseline healthy behaviours (non-smoker, moderate alcohol intake, physically active, frequent fruit/vegetable intake). Adjusted hazard ratios (95% confidence intervals) for incident CHD in Europeans who had three, two, one, and zero compared to four health behaviours were 1.33 (0.78–2.29), 1.96 (1.15–3.33), 1.36 (0.74–2.48) and 2.45 (1.18–5.10), respectively, p-trend = 0.025. In South Asians, corresponding HRs were 2.88 (1.33–6.24), 2.28 (1.06–4.91), 3.36 (1.53–7.39) and 3.48 (1.38–8.81), p-trend = 0.022. The results were similar for incident CVD; Europeans HR 2.12 (1.14–3.94), p–trend = 0.014; South Asians HR 2.73 (1.20–6.21), p-trend = 0.018. The population attributable fraction in Europeans was 43% for CHD and 28% for CVD. In South Asians it was 63% and 51% respectively.

Conclusions

Lack of adherence to four combined health behaviours was associated with 2 to 3-fold increased risk of incident CVD in Europeans and South Asians. A substantial population impact in the South Asian group indicates important potential for disease prevention in this high-risk group by adherence to healthy behaviours.
