Advance care planning: does patient gender make a difference?

BACKGROUND: Although it has received little study, gender may significantly affect patients' attitudes about advance care planning. METHODS: We asked 26 Mexican American (14 male, 12 female), 18 European American (7 male, 11 female), and 14 African American (7 male, 7 female) inpatients for their attitudes about advance care planning and dying. Coders of different ethnicities and genders performed independent, blinded content analyses of responses. RESULTS: The interviews identified 40 themes. Five, including "Advance directives (ADs) improve the chances a patient's wishes will be followed," characterized both genders of all 3 ethnic groups. Although no individual themes distinguished the genders across ethnic groups, 3 meta-themes--or clusters of related themes--did. Men's end-of-life wishes addressed functional outcome alone, but women's wishes addressed other factors, too. Men felt disempowered by the health system, but women felt empowered. Men feared harm from the system, but women anticipated benefit. Each ethnic group expressed these gender differences uniquely. For example, most Mexican American men preferred death to disability, believed "the health care system controls treatment," and wanted no "futile" life support. In contrast, most Mexican American women expressed wishes only about care other than life support (especially about when and where they wanted to die), believed ADs "help staff know...(such) wishes," and trusted the system to "honor (written) ADs." CONCLUSION: Core cultural attitudes observed in both genders of 3 ethnic groups may extend to all Americans. Although core attitudes may support advance care planning for many Americans, health professionals should consider tailoring it to other, ethnic- and gender-specific attitudes.     

Rearrest: does HIV serostatus make a difference?

Correctional facilities have become collection and containment centres for HIV-seropositive individuals. This is due to factors that affect incarceration in general: past criminal behaviour, age and crime type. In addition, the sex trade industry, intravenous drug use and community instability are likely factors affecting this particular population. The objective of this study was to determine whether HIV-positive offenders have higher rates of rearrest than HIV-negative offenders. A sample of HIV-positive offenders (n = 57) were seen for mental health evaluation at the King County Correctional Facility (KCCF) in Seattle Washington. They were compared to a historical sample (n = 254) of HIV-negative individuals also from the KCCF. After three months, 50% of both samples had been rearrested. Using the log rank test in Kaplan-Meier survival analysis, statistical difference in the relative risk of rearrest occurred for the HIV-positive group (logrank = 0.03). Statistical adjustment for mental illness, age, race, ethnicity, substance abuse history and past criminal history did not affect rearrest significantly. Nonetheless, HIV-positive individuals who presented with mental health needs appeared to be significantly more vulnerable to rearrest after the first three months of release into the community.     

Intravenous inotropic agents in the intensive therapy unit: do they really make a difference?

Part of the management of refractory heart failure is treatment aimed at preventing organ damage due to inadequate oxygen delivery, improving hemodynamics, and maximizing cardiac output while maintaining only mildly elevated ventricular filling pressures The aim of this paper is to review the most updated indications on intravenous inotropic agents, and to compare their cardiac and peripheral effects. Finally, clinical implications of their use (alone or in combination) are reviewed.     

Diagnosing collagenous colitis: does it make a difference?

Collagenous colitis is part of the spectrum of disorders known as microscopic colitis, which also include lymphocytic colitis and a mixed disorder with both a collagen band present and also intra-epithelial lymphocytes. Collagenous colitis appears to be caused by mucosal injury from toxins in the faecal stream. The collagen band is a result of the underlying inflammatory process and not the cause of symptoms. The diagnosis is based on colonic mucosal pathology and a compatible clinical presentation. Treatment is empiric and ranges from no therapy, to anti-inflammatory or anti-secretory agents, to diverting ileostomy.     

Beating heart surgery: does it make a difference?

Beating heart techniques were introduced into coronary artery bypass graft (CABG) surgery in the mid 1990s in an attempt to decrease the complications associated with the use of cardiopulmonary bypass. Significant advances in technique and technology, including suction stabilizers and exposure devices, have now allowed all coronary vessels to be routinely approached without the support of cardiopulmonary bypass, while maintaining hemodynamic stability. Currently, approximately 25% of all CABG is performed without cardiopulmonary bypass in the United States. An extensive body of literature attests to the strong interest in the technique and the outcomes available for analysis. Although randomized trials do not yet show a mortality benefit, they are all underpowered to do so. A review of large retrospective databases does appear to demonstrate a mortality benefit, but patient selection contributes bias. Strong evidence of benefit exists for blood loss/transfusion, postoperative renal failure, sternal infection, myocardial injury, extubation time, length of stay, and cost savings. Particular benefit is apparent in high-risk patient subgroups, including the elderly, reoperative patients, and those with significant comorbidities. Off-pump CABG does appear to make a difference in improved outcomes by maintaining the excellent results of traditional on-pump CABG, but with less perioperative complications.     

Trends in financial satisfaction: does poverty make a difference?

Gerontological studies on financial satisfaction have been limited by the dearth of longitudinal research and the lack of research that includes the concept of poverty. In order to bridge these gaps, this longitudinal study examines and compares the intracohort and intercohort effects on financial satisfaction trends by poverty status among Americans age 45 and above, using data from the General Social Surveys. The results suggest that for both the poor and the non-poor, changes in financial satisfaction trends are mostly due to strong negative intercohort effects, indicating that younger cohorts are less satisfied financially than the older ones. There appears to be a significant difference in the intercohort effects of financial satisfaction trends between the poor and the non-poor. However, such difference can be accounted for by the differences in the effects of education and social comparison (or relative deprivation) on financial satisfaction between the poor and the non-poor.     

Blood pressure-related cognitive decline: does age make a difference?

Systolic and diastolic blood pressures have been inversely related to cognitive performance in prospective and cross-sectional studies. However, in large, community-based samples, these findings have been limited to older adults. In this 20-year longitudinal study, we examined the relationship between baseline blood pressure and cognitive decline for 529 participants using 2 age groups (18 to 46 years and 47 to 83 years). Cognitive performance was measured over multiple examinations with the Wechsler Adult Intelligence Scale from which 4 scores were derived by factor analysis. A 2-stage growth curve method of analysis was used to model cognitive change. Results indicated that higher levels of baseline systolic blood pressure, diastolic blood pressure, mean arterial pressure, and blood pressure categories as defined by the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure were significantly associated with decline in Visualization/Fluid abilities in both younger and older age groups. Young adults are as susceptible to blood pressure-related longitudinal decline in cognitive performance as are older adults.     

Hepatic steatosis and insulin resistance: does etiology make a difference?

BACKGROUND/AIMS: To ascertain whether the etiology of hepatic steatosis modulates insulin resistance (IR) and to determine the predictors of IR. METHODS: We studied IR through HOMA IR in 146 subjects, 99 of whom had ultrasonographic and/or histologic steatosis. Twenty-two had familial heterozygous hypobetalipoproteinemia (FHBL), 48 had non-alcoholic fatty liver disease (NAFLD), 34 HCV infection (17 with HCV1b, 17 with HCV3a) and 42 were healthy controls without steatosis. RESULTS: Steatosis was present in 77.3% of FHBL and, by enrolment criteria, in all NAFLD and HCV cases. Overall HOMA-IR correlated with BMI and GGT (P<0.01). FHBL and healthy groups had similar HOMA-IR and GGT values, whereas higher levels were observed in HCV and NAFLD. HCV3a and FHBL patients were hypolipidemic. HOMA-IR was similar in FHBL patients and controls and lower than in HCV and NAFLD. FHBL patients had a high extent of steatosis, similar to that observed in HCV3a, but lower grading and staging than NAFLD and HCV. At multivariate analysis, steatosis and GGT predicted HOMA-IR. CONCLUSIONS: Data suggest that not all hepatic fat associates with IR. FHBL patients, for some aspects, resemble HCV3a infection, possibly suggesting a shared steatogenic mechanism. Among steatotic patients serum GGT levels is the independent predictor of IR.     

The medical emergency team: does it really make a difference?

Abstract
Hospital systems are failing the critically ill. This has been well documented in many countries around the world, with detailed reports of suboptimal care prior to intensive care and high rates of serious adverse events, including death. These events are potentially preventable, but insufficient attention has been directed towards developing solutions to these important problems to date.
The medical emergency team (MET) is a system approach that promotes early and appropriate inter­vention in the care of critically ill hospital patients. The benefits of the MET in terms of absolute in-patient ­mortality and cardiac arrest rates are not yet well-defined, although preliminary studies are promising.
The MET does provide a potentially beneficial impact on many other aspects of patient care. These benefits include: (i) facilitating an integrated and coordinated approach to patient care across the hospital, (ii) increasing awareness of at-risk patients, (iii) encouraging early referral of seriously ill patients to clinicians with expertise in critical care and (iv) providing a foundation for quality initiatives for hospital-wide care of the seriously ill.
The MET also empowers nursing staff and junior medical staff to call for immediate assistance in cases where they are seriously concerned about a patient, but may not have the experience, knowledge, confidence or skills necessary to manage them appropriately. (Intern Med J 2003; 33: 511−514)     

Symptoms in acute coronary syndromes: does sex make a difference?

Background

Coronary heart disease is a major problem in both men and women, but several studies have shown sex differences in symptoms of acute coronary syndromes (ACS). Some findings, however, have been disparate and inadequate, and thus a comprehensive overview of this literature would be of value.

Method

Fifteen studies that identified symptoms of ACS for both women and men were examined through a review of the literature from 1989 to 2002. Terms used for the search included “myocardial infarction,” “symptoms,” “gender differences,” and “acute coronary syndromes.”

Results

Although chest pain was the most common symptom in both men and women, several differences were also noted. In all types of ACS, women had significantly more back and jaw pain, nausea and/or vomiting, dyspnea, indigestion, and palpitations. In a number of studies, which solely sampled patients with acute myocardial infarction, women demonstrated more back, jaw, and neck pain and nausea and/or vomiting, dyspnea, palpitations, indigestion, dizziness, fatigue, loss of appetite, and syncope. Men reported more chest pain and diaphoresis in the myocardial infarction sample. The designs and methodologies of the studies varied considerably.

Conclusion

In addition to the typical symptom of chest pain in ACS, women experience other atypical symptoms more frequently than men. Thus, there may be sex differences in the symptoms of ACS, differences that have a bearing not only on clinical practice, but also on the interpretation of available clinical studies and the design of future investigations.     

Fistula-in-ano: do antibiotics make a difference?

Background The objective of this study was to evaluate the hypothesis that antibiotics in conjunction with drainage of anorectal abscesses will reduce the incidence of fistulae formation. The impact of age and associated comorbidity on the formation of fistulae were also evaluated.Methods Patients with a diagnosis of anorectal abscesses were identified from the database of a single colorectal practice. Demographic data, comorbidity, antibiotic usage, and fistulae formation were collected from review of patient's charts and phone contact. Statistical analysis was performed with the two-sided Fisher's exact and Wald's chi-square tests.Results Fifty-six patients with complete data were analyzed. The overall fistulae formation rate was 32%. Of all patients, 45% received a course of broad-spectrum antibiotics at the time of drainage and 48% of patients had associated comorbidity. Although trends were evident, there were no statistical significant associations between fistulae formation and age, comorbidity, and antibiotics.Conclusion Although not statistically significant, there was a trend that antibiotics and age >45 years may be protective against the formation of fistulae. Similarly, the data suggest that the presence of comorbidity may increase the risk of fistula formation. We are encouraged by this result and propose to conduct a larger randomized prospective study.Poster presentation at the American Society of Colon and Rectal Surgeons, May 2004, Dallas.     

Speckle tracking analysis in intensive care unit: A toy or a tool?

The use of conventional echocardiography in the intensive care unit (ICU) is today established to assess left and right ventricular systolic function, for preload determination and procedural guidance. Next step in ICU echocardiography could be the use of novel ultrasound techniques such as strain echocardiography to assist in the management of patients with acute coronary syndrome, heart failure, or pulmonary embolism. This review has gathered the available evidence supporting the incremental value of strain in the diagnostic workup of cardiac diseases treated in ICU.     

Physical activity intervention in older adults: does a participating partner make a difference?

Social integration and social support are expected to facilitate the adoption and maintenance of physical activity. In the context of a physical activity intervention, we distinguished three partner status groups, serving as an indicator of social integration. It was hypothesized that individuals whose partner also participated in the intervention, as opposed to individuals whose partners did not participate, or individuals without an intimate partner, would benefit more in terms of their physical activity. In a second step, a differential prediction pattern of social support on physical activity for each of the three partner status groups was investigated. The study involved 302 men and women (aged 60–95 years) and included two measurement points in time: A baseline assessment with a leaflet intervention to foster physical activity, and a 4-week follow-up assessment. In participants whose partners took part in the intervention, physical activity increased substantially over time, whereas it did not change in those individuals whose partners were not involved in the intervention, and it did not change in singles. Social support was positively related to physical activity when couples participated together in the intervention, but it was negatively related in singles or when partners did not participate. Social support appeared to be beneficial for physical activity in older adults when both partners participate in the intervention, which might reflect joint exercise or reciprocal exercise support. Singles or those with nonparticipating partners are not only less active, they might also be impeded by misguided support that could be perceived as social control.     

Older adults with asthma: does age of asthma onset make a difference?

Abstract

Objective: Older adults with asthma can develop symptoms early in life or during adulthood. Differences between these groups may have diagnostic and therapeutic implications. Our goal was to identify differences in demographics, control, quality of life and healthcare utilization between those with long-standing asthma (LSA) and late-onset asthma (LOA). Methods: Data from a cross-sectional study of asthma patients over age 65 were analyzed. LSA or LOA was based on age of diagnosis (before or after age 40). Demographic and asthma specific information were analyzed, and allergy prick tests and lung function testing (spirometry and FENO) were performed. Results: After regression analysis, LSA subjects were more likely to demonstrate positive prick tests (92 versus 71%, p?=?0.04), with both groups demonstrating higher levels of atopy than previously reported. LSA subjects were also more likely to have received a peak flow meter (p?=?0.07). LOA subjects were more likely to have moderate or severe asthma (OR?=?3.1, p?=?0.05), and had higher FENO readings (p?=?0.02). They also had more hospitalizations (p?=?0.04), though significance was lost after regression analysis. No differences were noted in demographic information, medical comorbidities, spirometry, compliance, asthma control, or asthma quality of life between LSA and LOA subjects. Conclusion: LSA subjects are more atopic and more likely to be given a peak flow meter, while LOA subjects have higher FENO levels and more severe asthma. Defining age of asthma onset may help improve treatment recommendations and outcomes for older adults.     

Short-term outcomes of acute knee injuries: does the provider make a difference?

OBJECTIVE: To compare the short-term outcomes of acute knee injuries treated by specialists and generalists. METHODS: Using patient logs, 168 adults with acute knee injuries were identified; 131 (78%) completed a questionnaire 3 months after initial presentation. RESULTS: The mean age of the 77 male and 54 female responders was 34.6 years (range 18-73 years). The injuries were classified as mild (n = 35), moderate (n = 75), or severe (n = 21). Most responders were satisfied with their care and outcome, but 22% noted some functional limitations. The 59 patients seeing an orthopedist were more likely to have had a severe injury, more physician visits, activity limitations, lost time from work or recreation, and more pain when compared with the 72 patients who never saw an orthopedist. Excluding surgical patients, however, satisfaction was not significantly different by provider. After multivariate modeling (adjusting for age, sex, injury severity, and diagnosis), there was no significant association between having seen an orthopedist and either treatment success or satisfaction. CONCLUSION: With the exception of time lost for recuperation in our community there is little difference in short-term outcome for patients with acute knee injury not undergoing surgery, regardless of the specialty of the treating physician.
