Laparoscopic Sacral Colpopexy: A Proposed Technique

This case report describes a laparoscopic sacral colpopexy using Mersilene mesh in a patient with complete vaginal vault prolapse. Mersilene mesh was placed as a hammock between the vaginal apex and the anterior surface of the sacrum, using intracorporeal needles and an extracorporeal knot tying technique. Minor modifications are made from the traditional abdominal approach, because the patient had previously undergone a pelvic lymphadenectomy and vaginal cuff radiation for a stage IB grade 1 adenocarcinoma of the endometrium

Residential Exposure to Traffic-Related Air Pollution and Survival after Heart Failure

Background: Although patients with heart failure (HF) have been identified as particularly susceptible to the acute effects of air pollution, the effects of long-term exposure to air pollution on patients with this increasingly prevalent disease are largely unknown. Objective: This study was designed to examine the mortality risk associated with residential exposure to traffic-related air pollution among HF patients. Methods: A total of 1,389 patients hospitalized with acute HF in greater Worcester, Massachusetts, during 2000 were followed for survival through December 2005. We used daily traffic within 100 and 300 m of residence as well as the distance from residence to major roadways and to bus routes as proxies for residential exposure to traffic-related air pollution. We assessed mortality risks for each exposure variable using Cox proportional hazards models adjusted for prognostic factors. Results: After the 5-year follow-up, only 334 (24%) subjects were still alive. An interquartile range increase in daily traffic within 100 m of home was associated with a mortality hazard ratio (HR) of 1.15 [95% confidence interval (CI), 1.05–1.25], whereas for traffic within 300 m this association was 1.09 (95% CI, 1.01–1.19). The mortality risk decreased with increasing distance to bus routes (HR = 0.88; 95% CI, 0.81–0.96) and was larger for those living within 100 m of a major roadway or 50 m of a bus route (HR = 1.30; 95% CI, 1.13–1.49). Adjustment for area-based income and educational level slightly attenuated these associations. Conclusions: Residential exposure to traffic-related air pollution increases the mortality risk after hospitalization with acute HF. Reducing exposure to traffic-related emissions may improve the long-term prognosis of HF patients

Long-term Exposure to PM2.5PM_{2.5} and Incidence of Acute Myocardial Infarction

Background: A number of studies have shown associations between chronic exposure to particulate air pollution and increased mortality, particularly from cardiovascular disease, but fewer studies have examined the association between long-term exposure to fine particulate air pollution and specific cardiovascular events, such as acute myocardial infarction (AMI). Objective: We examined how long-term exposure to area particulate matter affects the onset of AMI, and we distinguished between area and local pollutants. Methods: Building on the Worcester Heart Attack Study, an ongoing community-wide investigation examining changes over time in myocardial infarction incidence in greater Worcester, Massachusetts, we conducted a case–control study of 4,467 confirmed cases of AMI diagnosed between 1995 and 2003 and 9,072 matched controls selected from Massachusetts resident lists. We used a prediction model based on satellite aerosol optical depth (AOD) measurements to generate both exposure to particulate matter ≤ 2.5 μm in diameter (PM$_{2.5}$) at the area level (10 × 10 km) and the local level (100 m) based on local land use variables. We then examined the association between area and local particulate pollution and occurrence of AMI. Results: An interquartile range (IQR) increase in area PM$_{2.5}$ (0.59 μg/m$^3$) was associated with a 16% increase in the odds of AMI (95% CI: 1.04, 1.29). An IQR increase in total PM$_{2.5}$ (area + local, 1.05 μg/m$^3$) was weakly associated with a 4% increase in the odds of AMI (95% CI: 0.96, 1.11). Conclusions: Residential exposure to PM$_{2.5}$ may best be represented by a combination of area and local PM$_{2.5}$, and it is important to consider spatial gradients within a single metropolitan area when examining the relationship between particulate matter exposure and cardiovascular events

Temporal trends in cardiogenic shock complicating acute myocardial infarction

BACKGROUND: Limited information is available on trends in the incidence of and mortality due to cardiogenic shock complicating acute myocardial infarction. We studied the incidence of cardiogenic shock complicating acute myocardial infarction and in-hospital death rates among patients with this condition in a single community from 1975 through 1997. METHODS: We conducted an observational study of 9076 residents of metropolitan Worcester, Massachusetts, who were hospitalized with confirmed acute myocardial infarction in all local hospitals during 11 one-year periods between 1975 and 1997. Our study included periods before and after the advent of reperfusion therapy. RESULTS: The incidence of cardiogenic shock remained relatively stable over time, averaging 7.1 percent among patients with acute myocardial infarction. The results of a multivariable regression analysis indicated that the patients hospitalized during recent study years were not at a substantially lower risk for shock than patients hospitalized in the mid-to-late 1970s. Patients in whom cardiogenic shock developed had a significantly greater risk of dying during hospitalization (71.7 percent) than those who did not have cardiogenic shock (12.0 percent, P\u3c0.001). A significant trend toward an increase in in-hospital survival among patients with cardiogenic shock in the mid-to-late 1990s was found in crude and adjusted analyses. CONCLUSIONS: Our findings indicate no significant change in the incidence of cardiogenic shock complicating acute myocardial infarction over a 23-year period. However, the short-term survival rate has increased in recent years at the same time as the use of coronary reperfusion strategies has increased

Survival after hospital discharge for ST-segment elevation and non-ST-segment elevation acute myocardial infarction: a population-based study

BACKGROUND: Limited recent data are available describing differences in long-term survival, and factors affecting prognosis, after ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), especially from the more generalizable perspective of a population-based investigation. The objectives of this study were to examine differences in post-discharge prognosis after hospitalization for STEMI and NSTEMI, with a particular focus on factors associated with reduced long-term survival. METHODS: We reviewed the medical records of residents of the Worcester, MA, USA metropolitan area hospitalized at eleven central Massachusetts medical centers for acute myocardial infarction (AMI) during 2001, 2003, 2005, and 2007. RESULTS: A total of 3762 persons were hospitalized with confirmed AMI; of these, 2539 patients (67.5%) were diagnosed with NSTEMI. The average age of study patients was 70.3 years and 42.9% were women. Patients with NSTEMI experienced higher post-discharge death rates with 3-month, 1-year, and 2-year death rates of 12.6%, 23.5%, and 33.2%, respectively, compared to 6.1%, 11.5%, and 16.4% for patients with STEMI. After multivariable adjustment, patients with NSTEMI were significantly more likely to have died after hospital discharge (adjusted hazards ratio 1.28; 95% confidence interval 1.14-1.44). Several demographic (eg, older age) and clinical (eg, history of stroke) factors were associated with reduced long-term survival in patients with NSTEMI and STEMI. CONCLUSIONS: The results of this study in residents of central Massachusetts suggest that patients with NSTEMI are at higher risk for dying after hospital discharge, and several subgroups are at particularly increased risk

Trends and Characteristics Associated with the Risk of Re-hospitalization in Patients Discharged from the Hospital after Acute Myocardial Infarction

BACKGROUND: Despite encouraging declines in short-term mortality in patients hospitalized with acute myocardial infarction (AMI), repeat hospitalizations among those discharged from the hospital after AMI remain a major clinical and public health concern. Few studies, however, have described the relatively contemporary magnitude, factors associated with, as well as decade long trends in repeat hospitalizations for cardiovascular disease (CVD) and other causes in patients discharged from the hospital after AMI. METHODS: We reviewed the medical records of 6,018 residents of the Worcester (MA) metropolitan area who were hospitalized for AMI in 6 biennial periods between 1999 and 2009. Re-hospitalizations for any reason were recorded over a 2-year follow-up period. RESULTS: The average age of our study population was 70.3 years and 56.4% were men. Overall, 48.1% of our sample had at least 1 re-hospitalization for any cause after hospital discharge for AMI over the 2-year follow-up period. Of these, 45.7% of the repeat hospitalizations were attributed to CVD, 42.1% were non-CVD related, and 10.6% were due to AMI. The frequency of re-hospitalizations due to any cause declined slightly between 1999 and 2009 from 47.1% to 45.4% , marginally increased in those with CVD (from 46.3% to 47.9%) or non-CVD causes (from 36.9% to 38.3%), while the proportion of patients re-hospitalized for AMI decreased from 16.9% in 1999 to 13.9% in 2009. Older patients, those who developed an NSTEMI, who had a history of selected CVD and Non-CVD comorbidities, and who had received a percutaneous coronary intervention were more likely to have been re-hospitalized during the 2-year follow-up period, as compared with those who were not re-hospitalized (Table 1). CONCLUSIONS: The present results provide insights into the magnitude and causes of re-hospitalizations among patients discharged from the hospital after AMI .Risk of re-hospitalization after AMI was particularly high among older patients presenting with selected comorbidities

Trends in the medical management of patients with heart failure

BACKGROUND: Despite the availability of effective therapies, heart failure (HF) remains a highly prevalent disease and the leading cause of hospitalizations in the U.S. Few data are available, however, describing changing trends in the use of various cardiac medications to treat patients with HF and factors associated with treatment. The objectives of this population-based study were to examine decade-long trends (1995 - 2004) in the use of several cardiac medications in patients hospitalized with acute decompensated heart failure (ADHF) and factors associated with evidence-based treatment. METHODS: We reviewed the medical records of 9,748 residents of the Worcester, MA, metropolitan area who were hospitalized with ADHF at all 11 central Massachusetts medical centers in 1995, 2000, 2002, and 2004. RESULTS: Between 1995 and 2004, respectively, the prescription upon hospital discharge of beta-blockers (23%; 67%), angiotensin pathway inhibitors (47%; 55%), statins (5%; 43%), and aspirin (35%; 51%) increased markedly, while the use of digoxin (51%; 29%), nitrates (46%; 24%), and calcium channel blockers (33%; 22%) declined significantly; nearly all patients received diuretics. Patients in the earliest study year, those with a history of obstructive pulmonary disease or anemia, incident HF, non-specific symptoms, and women were less likely to receive beta blockers and angiotensin pathway inhibitors than respective comparison groups. In 2004, 82% of patients were discharged on at least one of these recommended agents; however, only 41% were discharged on medications from both recommended classes. CONCLUSIONS: Our data suggest that opportunities exist to further improve the use of HF therapeutics

Magnitude and Characteristics of Patients Who Survived an Acute Myocardial Infarction

BACKGROUND: The purpose of this study was to describe the magnitude and characteristics of patients who did not experience any significant major adverse cardiovascular event early (within 6 weeks) and late (during the first year) after hospital discharge for an acute myocardial infarction (AMI). METHODS AND RESULTS: Data from 12 243 patients discharged after an AMI from 233 sites across the United States in the TRANSLATE-ACS (Treatment With ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) study were analyzed. Multivariable adjusted regression analyses modeled factors associated with 6-week and 1-year survivors who did not experience a recurrent AMI, stroke, unplanned coronary revascularization, or rehospitalization for unstable angina/chest pain during these time periods. The average age of this study population was 60.0 years, 72.0% were men, and 87.9% were white. In this population, 92.4% were classified as early low-risk survivors and 76.3% were classified as late low-risk survivors of an AMI. Factors associated with being an early and late postdischarge survivor included being male and having single-vessel coronary artery disease at the patient\u27s index hospitalization. Patients who were not first seen with any chronic health condition, had an index hospital stay of \u3c /=3 days, and had high baseline quality-of-life scores were more likely to be late low-risk survivors. CONCLUSIONS: Identifying low-risk survivors of an AMI may permit healthcare providers to focus more intensive efforts and interventions on those at higher risk of experiencing adverse cardiovascular events during the postdischarge transition period.

Trends in the magnitude of chronic conditions in patients hospitalized with a first acute myocardial infarction

Background: Among adults with heart disease, there is a high prevalence of concomitant chronic medical conditions. We studied patients with a first acute myocardial infarction to describe: sample population characteristics; trends of the most prevalent pairs of chronic conditions; and differences in hospital management according to burden of these morbidities. Methods and Results: Patients (n = 1,564) hospitalized with an incident AMI at the 3 major medical centers in central Massachusetts during 2005, 2011, and 2015 comprised the study population. Hospital medical records were reviewed to identify 11 more prevalent chronic conditions. The median age of this population was 68 years and 56% were men. The median number of previously diagnosed chronic conditions was 2. Patients hospitalized during 2015 were more likely to be younger than those hospitalized in the earliest study cohorts. The most common pairs of chronic conditions for those hospitalized in 2005 were: anemia-chronic kidney disease (31%), chronic kidney disease-heart failure (30%), and stroke-atrial fibrillation (27%). Among patients hospitalized during 2011, chronic kidney disease-heart failure (29%), hypertension-hyperlipidemia (27%), and hypertension-diabetes (27%) were the most common pairs whereas hypertension-hyperlipidemia (43%), diabetes-heart failure (30%), and chronic kidney disease-diabetes (23%) were the most frequent pairs recorded in 2015. There was a significant decrease in the odds of undergoing cardiac catheterization and a percutaneous coronary intervention in those with higher chronic disease burden in the most recent as compared to earliest study years. Conclusions: Our findings highlight the magnitude of chronic conditions in patients with AMI and the challenges of caring for this vulnerable population
