Comprehensive health status assessment of centenarians: results from the 1999 large health survey of veteran enrollees

BACKGROUND: Information on the health status of centenarians provides a means for understanding the health care needs of this growing population. Therefore, we examined the health status of a national cohort of centenarian veteran enrollees. METHODS: Ninety-three centenarian veteran enrollees returned a complete health history questionnaire, which included questions about sociodemographic information, age-associated conditions, health behaviors, health-related quality of life as measured by the Veterans SF-36, and change in health status. RESULTS: Centenarian veteran enrollees are a group with major impairment across multiple dimensions of health-related quality of life despite having a relatively low prevalence of diseases. They had considerable physical limitations as reflected by their physical health summary scores (26.2 +/- 8.3). However, their mental health was comparatively good (mental health summary score 44.1 +/- 12.5). Compared to younger elderly veterans (ages 85-99), centenarians had a lower prevalence of hypertension, angina or myocardial infarction, diabetes, and chronic low back pain (p <.05). Centenarians had significantly worse physical functioning, role physical, vitality, and social functioning scores than did younger elderly veterans. The two groups did not differ in their general health, bodily pain, role emotional, and mental health scores. Centenarians did not perceive much decline in their physical or mental health during the preceding year. CONCLUSIONS: Centenarian veteran enrollees are a group with a low number of age-associated diseases and good mental health despite substantial physical limitations. These results support future studies of services directed toward improvement of function as opposed to those focused solely on the treatment of diseases.     

Pressure on Sports Medicine Clinicians to Prematurely Return Collegiate Athletes to Play After Concussion

Context

 Anecdotal and qualitative evidence has suggested that some clinicians face pressure from coaches and other personnel in the athletic environment to prematurely return athletes to participation after a concussion. This type of pressure potentially can result in compromised patient care.

Objective

 To quantify the extent to which clinicians in the collegiate sports medicine environment experience pressure when caring for concussed athletes and whether this pressure varies by the supervisory structure of the institution''s sports medicine department, the clinician''s sex, and other factors.

Design

 Cross-sectional study.

Setting

 Web-based survey of National College Athletic Association member institutions.

Patients or Other Participants

 A total of 789 athletic trainers and 111 team physicians from 530 institutions.

Main Outcome Measure(s)

 We asked participants whether they had experienced pressure from 3 stakeholder populations (other clinicians, coaches, athletes) to prematurely return athletes to participation after a concussion. Modifying variables that we assessed were the position (athletic trainer, physician) and sex of the clinicians, the supervisory structure of their institutions'' sports medicine departments, and the division of competition in which their institutions participate.

Results

 We observed that 64.4% (n = 580) of responding clinicians reported having experienced pressure from athletes to prematurely clear them to return to participation after a concussion, and 53.7% (n = 483) reported having experienced this pressure from coaches. Only 6.6% (n = 59) reported having experienced pressure from other clinicians to prematurely clear an athlete to return to participation after a concussion. Clinicians reported greater pressure from coaches when their departments were under the supervisory purview of the athletic department rather than a medical institution. Female clinicians reported greater pressure from coaches than male clinicians did.

Conclusions

 Most clinicians reported experiencing pressure to prematurely return athletes to participation after a concussion. Identifying factors that are associated with variability in pressure on clinicians during concussion recovery can inform potential future strategies to reduce these pressures.Key Words: conflict of interest, organizational structure, sex, college

Key Points

• More than half of sports medicine clinicians had experienced pressure from coaches and athletes to return athletes to participation prematurely after a concussion.
• Clinicians experienced greater pressure from coaches at schools where the sports medicine department reported to the athletic department than at schools where the sports medicine department reported to an independent medical institution.
• Female clinicians experienced greater pressure from coaches than male clinicians experienced.
• More research is needed to determine how pressure affects clinical practice and whether pressure on clinicians affects return-to-participation decisions.

Addressing the health burden of mild traumatic brain injury from sport is increasingly considered a public health priority.¹ More than 450 000 college students participate in organized interscholastic sports each year.^2,3 Among collegiate athletes in contact and collision sports, Daneshvar et al⁴ estimated that 43 concussions are sustained per 100 000 athlete-exposures to a game or practice, which is nearly twice the rate of diagnosed concussions sustained by high school athletes competing in the same sports. This estimate likely understates the true incidence of concussions because many are undiagnosed.^5–8 Recent evidence^9–14 has suggested that repeated concussive and subconcussive brain trauma can lead to neurologic problems later in life, including changes in cognition and behavior.Conflict of interest in the care of concussed athletes is a topic of growing ethical discourse.^15–19 Writing for the Chronicle of Higher Education about US collegiate sport, Wolverton²⁰ painted a picture of colleges fraught with pressure on physicians and athletic trainers (ATs) from coaches and athletic administrators. A total of 101 clinicians who provide patient care for football teams in the National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision participated in the non–peer-reviewed study, and more than half reported that they had “felt pressure from football coaches to return concussed players to action before they were medically ready.”²⁰ Some of this pressure was attributed to conflicts of interest inherent in the organizational structure and incentives of sports medicine departments. In some instances, ATs reported directly to head football coaches.²⁰ Even in substantially lower-stakes youth sports, Bramley et al²¹ reported that a sample of hockey coaches indicated they would be more likely to allow an athlete who had sustained a concussion to continue participating if the game was considered important, such as for a championship. Consequently, clinicians in collegiate sports medicine departments may find themselves in a challenging situation: having ethical responsibilities to provide appropriate medical care to their patients while facing perceived or real pressure from their employers to return athletes to participation.^15–19,22 In a survey of sports medicine physicians in New Zealand, Anderson and Gerrard²³ observed that whereas all respondents expressed a sense of responsibility to their athlete patients, 72% also believed they had a responsibility to the team coach, and 55% believed they had a responsibility to team management.The National Athletic Trainers'' Association recently released a consensus statement detailing best practices for sports medicine management in secondary schools and colleges, including the advantages and disadvantages of different models of supervisory relationships in sports medicine.²⁴ Supervisory models in which ATs or team physicians are employed by athletic departments are described as having the potential for conflict of interest in the medical care provided to athletes. Pecci and Laursen²⁵ and Laursen²⁶ have advocated for sports medicine departments to be nested within medical units, such as university health centers, rather than athletic departments. They suggested that this organizational structure would reduce real and perceived conflicts of interest in the care of athletes and would have additional benefits, such as easier access to other health care providers and more centralized oversight of medical care.^25,26 Whereas these arguments are intuitive, no researchers have conducted an empirical evaluation of whether supervisory structure is systematically associated with different types of pressure on clinicians regarding the care of collegiate athletes who have sustained concussions.Another potentially important variable that could modify the pressure that clinicians experience is their sex. Approximately half of all ATs are women, but women represent only about one-quarter of full-time staff ATs and only 1 in 8 head ATs in collegiate sports medicine departments.^27–30 Some investigators³¹ have suggested that male and female ATs may have different experiences interacting with coaches and other ATs in the collegiate athletic environment. Mazerolle et al³¹ conducted qualitative interviews with 14 female NCAA Division I ATs and described how they “often encountered gender discrimination when working with a team sport coached by a man.” They described a perception that coaches view female ATs as “more sympathetic and less pragmatic” than male ATs and that this judgment undermines the coaches'' confidence in the care they provide athletes. This differential perception is reinforced by 2 surveys^32,33 in which male collegiate athletes reported being more comfortable receiving care from male ATs. Stereotypical judgments about women in the workplace tend to be strongest when women are an underrepresented minority, as is the case with female ATs in collegiate sports environments, and can inform the control strategies of individuals in positions of power.³⁴ Quantifying the extent to which pressure is experienced in the care of concussed athletes and whether it is modified by clinician characteristics such as sex are important steps in understanding whether institution-level intervention is needed.Therefore, the purpose of our study was to obtain empirical evidence about whether clinicians who provide care to US collegiate sports teams experienced pressure to prematurely clear athletes for participation after a concussion. We hypothesized that clinicians in sports medicine departments reporting to the athletic department would experience greater pressure from coaches and athletes than clinicians in departments reporting to medical institutions and that female clinicians would experience greater pressure from coaches and athletes than male clinicians would experience.

Context

Patients triggering rapid response team (RRT) intervention are at high risk for adverse outcomes. Data on symptom burden of these patients do not currently exist, and current symptom management and communication practices of RRT clinicians are unknown.

How do people interpret information about colorectal cancer screening: observations from a think‐aloud study

Background

The English NHS Bowel Cancer Screening Programme biennially invites individuals aged 60–74 to participate in screening. The booklet, ‘Bowel Cancer Screening: The Facts'' accompanies this invitation. Its primary aim is to inform potential participants about the aims, advantages and disadvantages of colorectal cancer screening.

Objective

To provide detailed commentary on how individuals process the information contained within ‘The Facts’ booklet.

Design, setting and participants

This study comprised of 18 interviews with individuals aged 45–60 and used a ‘think‐aloud’ paradigm in which participants read aloud the booklet. Participant utterances (verbal statements made in response to researcher‐led prompts) were transcribed and analysed using a combination of content and thematic analysis.

Results

A total of 776 coded utterances were analysed (mean = 43.1 per person; range = 8–95). While overall comprehension was satisfactory, several problem areas were identified such as the use of complex unfamiliar terminology and the presentation of numerical information. Specific sections such as colonoscopy risk information evoked negative emotional responses. Participants made several suggestions for ways in which comprehension might be improved.

Conclusion

Public perceptions of the NHS Bowel Cancer Screening Programme information materials indicated that specific aspects of the booklet were difficult to process. These materials may be an appropriate target to improve public understanding of the aims, benefits and disadvantages of colorectal cancer screening. These findings will contribute to a broader NIHR‐funded project that aims to design a supplementary ‘gist‐based’ information leaflet suitable for low literacy populations.     

Impact of renal insufficiency on short- and long-term outcomes after cardiac surgery

Background

Renal insufficiency is highly prevalent in North America and has been established as a nontraditional risk factor for cardiovascular disease. Cardiovascular disease remains the primary cause of mortality in the general population and is often treated with coronary artery bypass surgery (CABG). This population-based study aimed to determine the risk of nondialysis dependent renal insufficiency (RI) on the long-term outcomes of patients who undergo CABG.

Methods

Prospectively collected data from 26,506 patients were abstracted from the Cardiac Care Network database from 9 revascularization hospitals in Ontario, Canada. Multivariate regression analysis examined associations between preoperative RI and inhospital, 30-day, and 1-year mortality according to 3 levels of serum creatinine: <120 μmol/L (normal), 120 to 180 μmol/L (mild RI), and >180 μmil/L (moderate-severe RI) and 5 levels of creatinine clearance (Cockcroft-Gault): >100 mL/min (normal), 80 to 99 mL/min (mild impairment), 60 to 79 mL/min (mild-moderate impairment), 40 to 59 mL/min (moderate impairment), and <40 mL/min (severe impairment).

Results

The overall inhospital, 30-day, and 1-year mortality rates were 1.90%, 2.0%, and 4.5%, respectively. Patients with RI had greater overall comorbidity. After adjustment for confounding factors, RI was associated with the greater risk of both 30-day (odds ratio 3.7, 95% CI 2.3-5.8, P < .0001) and 1-year mortality (odds ratio 4.6, 95% CI 3.3-6.4, P < .0001).

Conclusion

Preoperative renal impairment should be recognized as a significant risk factor for mortality after CABG. A trend of increasing risk with severity of renal impairment was demonstrated for both 30-day and 1-year mortality in this large, population-based study.     

Partition site of the P1 plasmid.

We have defined a minimal partition site, parS, from the plasmid P1. It contains sufficient cis-acting information to direct accurate segregation of low-copy-number plasmids that contain it as long as the two essential P1 Par proteins are supplied in trans. The site is, at most, 34 base pairs and contains a perfect 13-base-pair inverted repeat. Site-directed mutations were made within the repeat sequence that abolished activity whether or not the symmetry of the palindrome was maintained. Partition appears to be a competitive process, as differentially marked plasmids carrying the same type of partition site are not independently segregated but are randomly distributed with respect to each other. We have studied competition between plasmids carrying various fragments encompassing the parS site. As expected, two plasmids carrying the minimal parS site compete with each other. However, a sequence that lies to the left of the minimal parS site acts as a major modulator of this competition, changing the specificity of the competitive effect completely. Thus, this adjacent sequence appears to be an important determinant of the specificity of the wild-type P1 partition system without being necessary for its efficient function.     

Safety of rush immunotherapy using a modified schedule: a cumulative experience of 893 patients receiving multiple aeroallergens.

Conventional immunotherapy (IT) is effective in treating allergic rhinitis, allergic asthma, and chronic rhinosinusitis. Disadvantages include poor compliance, delayed efficacy, and patient frustration. Rush IT, or rapid desensitization, offers the advantages of rapid response, improved compliance, and cost-effectiveness. Although premedication with corticosteroids and antihistamines dramatically reduces systemic reactions, safety remains a primary concern. Two separate half-day schedules with minor differences were used to rapidly desensitize 893 patients (aged 1.5-77 years) in two typical outpatient settings equipped to treat anaphylaxis. All patients exhibited positive skin-prick tests to perennial and seasonal allergens. Diagnoses included allergic rhinitis (857/96%), allergic asthma (505/57%), and chronic rhinosinusitis (384/43%). Five hundred sixty-eight patients were premedicated with prednisone and HI-antihistamine for 3 days. Three hundred twenty-five patients were premedicated for 3 days with prednisone and H1- and H2-blockade. The protocol's final dose ranged from 0.1 to 0.5 mL of a 1:1000 dilution of extracts manufactured by ALK and Greer Laboratories. Patients continued on to higher doses by resuming a conventional schedule. Eighteen patients (2.0%) experienced a mild systemic reaction. All responded to subcutaneous epinephrine and/or nebulized albuterol and were sent home after observation. One patient (0.1%) experienced true anaphylaxis and received appropriate treatment and observation. Our experience with rush IT confirms that maintenance IT can be reached quickly and safely under careful supervision. Caution must be exercised when using this procedure because anaphylaxis does occur. Systemic reactions occur less frequently using a lower targeted final dose than previously described in the literature.     

NIH conference. Lupus nephritis

Nephritis has long been considered one of the most ominous components of systemic lupus erythematosus. Accumulations of immune complexes and lymphoid cells in several locations within the kidney are the best-described elements of lupus nephritis. The extreme diversity of the renal changes indicates that many variables are likely to be involved. Inbred strains of lupus-prone mice have provided homogeneous subjects for study of pathogenesis and response to treatment. Comparable grouping of lupus nephritis in humans according to unique or dominant pathogenetic mechanisms is imprecise and limited by insufficient knowledge of the primary stimulus for the disease. Treatment is also imperfect and, at times, hazardous. Certain regimens incorporating cytotoxic drugs provide a significant therapeutic advantage over corticosteroids alone in the management of this disease.
