Patients’ perceptions of physicians’ recommendations for comfort care differ by patient age and gender

OBJECTIVE: To determine patient characteristics associated with patient and proxy perceptions of physicians’ recommendations for life-prolonging care versus comfort care, and with acceptance of such recommendations. DESIGN: Cross-sectional. SETTING: Five teaching hospitals in Denver, Colo. PATIENTS: We studied 239 hospitalized adults believed by physicians to have a high likelihood of dying within 6 months. MEASUREMENTS AND MAIN RESULTS: Interviews with patients or proxies were conducted to determine perceptions of physicians’ recommended goal of care and roles in decision making. RESULTS: Patients’ mean age was 66.6 years; 44% were women. In adjusted analysis, age greater than 70 years and female gender were associated with a higher likelihood of believing that comfort care had been recommended by the physician (odds ratio [OR], 3.70; 95% confidence interval [CI], 1.89 to 7.24; OR, 1.99; 95% CI, 1.04 to 3.84, respectively). Patients and proxies gave substantial decision-making authority to physicians: 29% responded that physicians dominate decision making, 55% that decision making is equally shared by physicians and patients, and only 16% that patients make decisions, Increasing age was associated with an increased likelihood of believing that physicians should dominate decision making (P<.005). CONCLUSIONS: Among patients with advanced illness, perceived comfort care recommendations were related to patient age and gender, raising concern about possible gender and age bias in physicians’ recommendations. Although all patients and proxies gave significant decision-making authority to physicians, older individuals were more likely to give physicians decision-making authority, making them more vulnerable to possible physician bias.

Use of non-invasive cardiac investigations to predict clinical endpoints after coronary bypass graft surgery in coronary artery disease patients: results from the prognosis and evaluation of risk in the coronary operated patient (PERISCOP) study.

AIMS: Little is known about which patients who have undergone coronary bypass surgery are at risk of future clinical cardiovascular events and may benefit from further medical treatment. We sought to determine if routine non-invasive cardiac investigations performed early after surgery were able to stratify the risk of cardiovascular events in this population. METHODS: Two thousand and sixty-five consecutive patients were enrolled in a prospective multicenter study (PERISCOP). Exercise testing, echocardiography, and 24-h ambulatory ECG monitoring were performed at day 20+/-10 after coronary bypass surgery. Follow-up was performed 1 year after coronary bypass surgery. Causes of all hospitalisation and death occurring within 1 year were documented and classified by an End-point Committee. The principal endpoint was the combination of all-cause deaths and cardiovascular events requiring hospitalisation (myocardial infarction, unstable or severe angina, stroke, congestive heart failure). RESULTS: The 1-year frequency of first events was 155 (8%). In multivariate analysis, exercise duration <420s (RR=1.68; 95% CI: 1.13-2.49), exercise induced ST segment depression >1mm (RR=1.90; 95% CI: 1.18-3.05), and left ventricular (LV) dysfunction (wall motion index <1.15) (RR=1.97; 95% CI: 1.10-3.51) were independent predictors of cardiovascular events and deaths. Ambulatory ECG monitoring had no predictive value. CONCLUSIONS: Exercise testing and echocardiography performed early after coronary bypass surgery are able to identify high-risk patients who may benefit from intensive secondary prevention.     

A vaccine manufacturer’s approach to address medical needs related to seasonal and pandemic influenza viruses

Abstract Vaccination is considered to be one of the most effective tools to decrease morbidity as well as mortality caused by influenza viruses.For the prevention of seasonal influenza, Fluarix ™ and FluLaval™ have been marketed since 1987 and 1992, respectively. Both vaccines have consistently been shown to meet or exceed the regulatory criteria for immunogenicity against the three strains H1N1, H3N2 and B, have a good safety profile, and are recommended for vaccinating children and adults of all ages.For the prevention of pandemic influenza, GlaxoSmithKline (GSK) has obtained licensure of a pre‐pandemic vaccine, Prepandrix ™. This split‐virus H5N1 adjuvanted with AS03, a proprietary oil‐in‐water emulsion‐based adjuvant system, has demonstrated broad immunity against drifted H5N1 strains and has been shown to be effective in preventing mortality and viral shedding in animal studies.The influenza vaccine portfolio of GSK addresses specific medical needs related to seasonal or pandemic influenza viruses, which remain an important public health threat worldwide.     

The current status of thalidomide in the management of multiple myeloma

Early anticancer research involving thalidomide was abandoned in the 1960s as the catastrophe surrounding the drug emerged, but research efforts were picked up in the 1990s when thalidomide's antiangiogenic and anti-tumour necrosis factor properties were explored. More than 50,000 patients with multiple myeloma are estimated to have been treated with thalidomide to date. Research with thalidomide provides clear and convincing evidence that thalidomide monotherapy is efficacious in relapsed and refractory patients with multiple myeloma. Results typically show a consistent 30% (95% confidence interval 27-32%) response rate (partial response + complete response, defined as a reduction of at least 50% in the monoclonal protein). Thalidomide treatment compares favourably with other typical treatments for multiple myeloma. In seven trials that included 332 patients, vincristine, adriamycin and dexamethasone (VAD) had a response rate of 39% (32-45%), while a trial in 193 patients showed a response rate with bortezomib of 27% (21-34%). The use of thalidomide in combination therapy could boost its efficacy further. More studies to look at the toxicity of the drug need to be carried out. Despite thalidomide's dark past, this drug is of major interest and could be brought back to clinical use in a controlled manner.     

Persistence of replication-competent HIV in both memory and naive CD4 T cell subsets in patients on prolonged and effective HAART

OBJECTIVE: To investigate the phenotypic features of infected lymphocytes in patients on prolonged and effective highly active antiretroviral therapy (HAART). DESIGN: We examined highly purified subsets of memory and naive CD4 T lymphocytes for the presence of replication-competent virus. METHODS: In 11 highly selected HAART-treated patients, we isolated highly purified CD45RO CD45RA CD4 T cells using a magnetic bead-based procedure. In some patients, a subsequent cell separation according to CD62L expression was performed. We quantified total viral DNA in freshly isolated T-cell subsets. To verify whether the virus was replication-competent, HIV RNA was measured in supernatants following cell activation. RESULTS: HIV DNA was detectable in the CD45RO and CD45RA CD4 T-cell subsets in 100% and 90% of the patients tested, respectively. In central memory CD45ROCD62L, effector memory CD45RO+CD62L-, truly naive CD45RACD62L, and CD45RA+CD62L- CD4 T cells, HIV DNA was found in 100%, 55%, 88%, and 50% of the patients tested respectively. HIV DNA was significantly higher in the CD45RO fraction than in the CD45RA subset and in the CD45ROCD62L fraction than in the three other CD45RA/ROCD62L+/- subsets. Detectable HIV RNA was found in the culture supernatants of CD45RO and CD45RA CD4 T-cell subsets in 80% and 66% of the patients tested respectively, and in CD45ROCD62L, CD45RO+CD62L-, CD45RACD62L, and CD45RA+CD62L- CD4 T cells in 100%, 100%, 100% and 50% of the patients tested respectively. CONCLUSIONS: In patients on prolonged and effective HAART, the pool of infected CD4 T lymphocytes consists predominantly of memory cells but also contains naive cells.     

Residential Trajectories of Street Youth—the Montréal Cohort Study

Little is known about the course of homelessness among youth between the ages of 18 and 25 despite the many characteristics distinguishing them from adolescents and from older street-involved populations. We examined the residential trajectories of homeless young adults in Montréal over a 21-month period and identified determinants of various trajectory profiles. The 365 study participants (79 % men, mean age 21.9 years) were followed for an average of 515 days (range 81–630 days). We assessed housing status with a questionnaire based on the residential follow-back calendar designed by the New Hampshire Dartmouth Research Center. Using latent growth analysis to examine achievement of residential stability over time, we observed three different trajectories: group 1 presented a low probability of housing throughout the entire study period; group 2 showed a high probability of early and stable housing; group 3 displayed a fluctuating pattern. Protective correlates of residential stability included high school education, birth in Canada, and presence of mental health problems. Drug abuse or dependence was associated with a decreased probability of housing.     

US Provider-Reported Diet and Physical Activity Counseling to Pregnant and Non-pregnant Women of Childbearing Age During Preventive Care Visits

Healthy diet, physical activity and appropriate weight gain during pregnancy contribute to healthy birth outcomes. The Institute of Medicine recommends that women receive counseling about diet and exercise during preconception, pregnancy and postpartum periods. We sought to determine how often healthcare providers report counseling women of childbearing age about diet or exercise and if such rates vary by pregnancy, overweight/obesity status or physician specialty. We combined the 2005–2010 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey to obtain nationally representative estimates of outpatient preventive care visits for women of child-bearing age (15–44 years). Accounting for survey design, we compared proportions of preventive visits that included diet/exercise counseling for pregnant women versus non-pregnant women and performed multivariable logistic regression models to estimate odds ratios. Providers reported counseling pregnant women about diet/exercise during 17.9 % of preventive care visits compared to 22.6 % of visits for non-pregnant women (P < 0.01, adj. OR 0.8, 95 % CI 0.7, 1.0). Overweight/obese pregnant (vs. non-pregnant) women were significantly less likely to receive diet/exercise counseling (adj. OR 0.7, CI 0.5, 0.9) as were women seen by OB/GYNs versus non-OB/GYNs (adj. OR 0.4, CI 0.3, 0.5). Our findings suggest that provider-reported diet/exercise counseling rates during preventive care visits for women of childbearing age vary by overweight/obesity and pregnancy statuses, as well as by provider specialty. Our data suggest that there may be missed opportunities to provide diet/exercise counseling and that increasing rates of counseling could result in improved maternal and infant health outcomes.     

Care and prejudice: moving beyond mistrust in the care relationship with addicted patients

Social representations of addiction and the resulting stigmatization have been widely described and studied in the literature, but their effects are no less problematic. These representations, which also occur in care settings, generate a climate of distrust which damages the therapeutic relationship, and its ethical quality. This article, combining clinical experience and an ethical stance, offers an original, innovating approach to the existence of distrust in care relationships in the area of addiction. Pragmatic approaches deriving from the human sciences and analytical philosophy provide an invitation to escape from the demanding climate of mistrust, and to take the gamble on trust so as to improve the quality of interactions between protagonists in care. In complementary fashion, a sociology of action can combat the disquiet generated by distrust through a new commitment to innovating forms of action. This “poetic” mode of action is legitimized by the reflection that backs it up, and by its presentation to peers qualified to approve it. Finally, continental moral philosophy underlines the importance of a carefully weighed commitment on the part of caregivers and addicted patients towards promises aiming to support a sincere care relationship, without damaging the therapeutic dynamic or the ethical quality by providing too many safety nets. This reflection is intended to achieve better identification of the clinical and ethical issues raised by mistrust, and inclusion of these aspects in the training of personnel and in care provision planning.
