Impact of daily strawberry consumption on blood pressure and arterial stiffness in pre- and stage 1-hypertensive postmenopausal women: a randomized controlled trial.

Growing evidence indicates that strawberries are cardioprotective. We conducted an eight-week randomized, double-blind, placebo-controlled, parallel arm clinical trial to investigate the effects of daily consumption of freeze-dried strawberry powder (FDSP) on blood pressure (BP) and arterial stiffness in pre- and stage 1-hypertensive postmenopausal women. Sixty postmenopausal women were randomly assigned to one of three groups: (1) control, (2) 25 g FDSP and (3) 50 g FDSP (n = 20 per group). Assessments of body weight, BP, arterial stiffness as measured by pulse wave velocity (PWV), and collection of blood samples for analyses of vasoactive and antioxidant molecules were performed at baseline, four and eight weeks. After eight weeks, systolic BP, as well as brachial- and femoral-ankle PWV were lower than baseline in the 25 g FDSP group (141 ± 3 to 135 ± 3 mmHg, P = 0.02; 15.5 ± 0.5 to 14.8 ± 0.4 m s-1, P = 0.03, and 11.0 ± 0.2 to 10.4 ± 0.2 m s-1, P = 0.02, respectively), whereas no statistically significant changes were observed in the control or 50 g FDSP groups. Plasma nitric oxide metabolite levels increased at four and eight weeks in the 50 g FDSP group compared to baseline (8.5 ± 1.2 to 13.6 ± 1.3 and 13.3 ± 1.5, respectively, P = 0.01), whereas no significant changes were observed in the control or 25 g FDSP groups. Serum levels of superoxide dismutase increased at four weeks returning to baseline levels at eight weeks in all three groups. Significant differences among groups were not detected for any of the parameters. Although BP and arterial stiffness improved in the 25 g FDSP group over time, a treatment effect was not observed. Thus, it would be premature to affirm that daily consumption of FDSP improves BP or vascular function in pre- and stage 1-hypertensive postmenopausal women. This trial was registered at as NCT02099578.

Fourth-Year Medical Student Charting of Older Persons' Cognitive and Functional Status.

BACKGROUND AND OBJECTIVES: Functional and cognitive impairment correlates with medical outcomes in older persons, yet documentation in the medical record is often inadequate. The purpose of this pilot study was to evaluate fourth year (M4) medical students' charting performance of cognition and functional status in older persons during non-geriatric clerkships using an audit tool. METHODS: The research assistants used a chart abstracting tool to retrospectively review patients' charts. The abstracting tool contained keywords and phrases to prompt the research assistants to look for any documentation of patient status in four domains: (1) delirium or acute confusional state, (2) chronic cognitive impairment, (3) activities of daily living, and (4) instrumental activities of daily living. The threshold was any mention of keywords in these domains. RESULTS: On non-geriatrics M4 clerkships in the hospital, students documented acute cognitive status (ACS) and presence or absence of chronic cognitive impairment (CCI) in 57% and 68% of cases respectively, with physicians and/or nurses doing it more often at 63% and 84%. Both students and other care providers documented ACS and CCI in the same charts 41% and 59% of the time, respectively. Students documented activities of daily living (ADLs) and instrumental activities of daily living (IADLs) 31% and 3% respectively, physicians and/or nurses 59% and 0%. CONCLUSIONS: Documentation of cognitive status in hospital charts for students and physicians was somewhat higher than in the literature. This may be because geriatrics is integrated into our 4-year curriculum. Documentation by both students and physicians was better for ADLs than IADLs and poor for IADLs overall.

Biocompatibility and microstructural analysis of osteopromotive property of allogenic demineralized dentin matrix.

PURPOSE: Bone grafting materials and methods have been used to compensate anatomical limitations and improve ridge and sinus structure for implant placement. The objective of this study was to evaluate the osteopromotive property of allogenic demineralized dentin matrix (DDM) as a bone grafting material using micro-computed tomography and blood biomarkers. MATERIALS AND METHODS: Two surgical bone defects were created on the skull of 30 female New Zealand White rabbits. Experimental defects in 24 rabbits were filled with allogenic DDM applying guided bone regeneration technique, while the control defects were covered by membrane without receiving the graft. In the remaining six rabbits, both defects were left empty and these rabbits served as control for blood biomarkers. The 24 experimental rabbits were sacrificed after 15, 30, 60, and 90 days (n = 6 at each time point). Blood samples were collected from all rabbits at the baseline, 48 hours postsurgery, and at each time point. RESULTS: Bone thickness was significantly higher in the experimental group at all time points. Micro-computed tomography results showed increased bone mass and superior bone quality in the experimental group. At all time points except for 48 hours postsurgery, the white blood cell count was numerically higher in control rabbits compared to experimental rabbits, suggesting a lack of inflammation or infection due to allogenic DDM. Bone-specific alkaline phosphatase activities were lower in both experimental and control groups at all time points in comparison to baseline values, which is indicative of either a lower rate of bone formation or bone turnover. CONCLUSIONS: Within the limitations of this study, allogenic demineralized dentin matrix significantly increased bone mass and improved bone quality without causing an inflammatory reaction or infection.

Daily apple versus dried plum: impact on cardiovascular disease risk factors in postmenopausal women.

BACKGROUND: Evidence suggests that consumption of apple or its bioactive components modulate lipid metabolism and reduce the production of proinflammatory molecules. However, there is a paucity of such research in human beings. OBJECTIVE: Women experience a lower rate of cardiovascular disease before menopause compared with men. However, after the onset of menopause, the risk of cardiovascular disease increases drastically due to ovarian hormone deficiency. Hence, we conducted a 1-year clinical trial to evaluate the effect of dried apple vs dried plum consumption in reducing cardiovascular disease risk factors in postmenopausal women. DESIGN: One-hundred sixty qualified postmenopausal women were recruited from the greater Tallahassee, FL, area during 2007-2009 and were randomly assigned to one of two groups: dried apple (75 g/day) or dried plum (comparative control). Fasting blood samples were collected at baseline, 3, 6, and 12 months to measure various parameters. Physical activity recall and 7-day dietary recall were also obtained. RESULTS: Neither of the dried fruit regimens significantly affected the participants' reported total energy intake throughout the study period. On the contrary, women who consumed dried apple lost 1.5 kg body weight by the end of the study, albeit not significantly different from the dried plum group. In terms of cholesterol, serum total cholesterol levels were significantly lower in the dried apple group compared with the dried plum group only at 6 months. Although dried plum consumption did not significantly reduce serum total cholesterol and low-density lipoprotein cholesterol levels, it lowered their levels numerically by 3.5% and 8%, respectively, at 12 months compared with baseline. This may explain the lack of significance observed between the groups. However, within the group, women who consumed dried apple had significantly lower serum levels of total cholesterol and low-density lipoprotein cholesterol by 9% and 16%, respectively, at 3 months compared with baseline. These serum values were further decreased to 13% and 24%, respectively, after 6 months but stayed constant thereafter. The within-group analysis also reported that daily apple consumption profoundly improved atherogenic risk ratios, whereas there were no significant changes in lipid profile or atherogenic risk ratios as a result of dried plum consumption. Both dried fruits were able to lower serum levels of lipid hydroperoxide and C-reactive protein. However, serum C-reactive protein levels were significantly lower in the dried plum group compared with the dried apple group at 3 months. CONCLUSIONS: There were no significant differences between the dried apple and dried plum groups in altering serum levels of atherogenic cholesterols except total cholesterol at 6 months. However, when within treatment group comparisons are made, consumption of 75 g dried apple (about two medium-sized apples) can significantly lower atherogenic cholesterol levels as early as 3 months. Furthermore, consumption of dried apple and dried plum are beneficial to human health in terms of anti-inflammatory and antioxidative properties.

Comparative effects of dried plum and dried apple on bone in postmenopausal women.

Aside from existing drug therapies, certain lifestyle and nutritional factors are known to reduce the risk of osteoporosis. Among the nutritional factors, dried plum or prunes (Prunus domestica L.) is the most effective fruit in both preventing and reversing bone loss. The objective of the present study was to examine the extent to which dried plum reverses bone loss in osteopenic postmenopausal women. We recruited 236 women, 1-10 years postmenopausal, not on hormone replacement therapy or any other prescribed medication known to influence bone metabolism. Qualified participants (n 160) were randomly assigned to one of the two treatment groups: dried plum (100 g/d) or dried apple (comparative control). Participants received 500 mg Ca plus 400 IU (10 µg) vitamin D daily. Bone mineral density (BMD) of lumbar spine, forearm, hip and whole body was assessed at baseline and at the end of the study using dual-energy X-ray absorptiometry. Blood samples were collected at baseline, 3, 6 and 12 months to assess bone biomarkers. Physical activity recall and 1-week FFQ were obtained at baseline, 3, 6 and 12 months to examine physical activity and dietary confounders as potential covariates. Dried plum significantly increased BMD of ulna and spine in comparison with dried apple. In comparison with corresponding baseline values, only dried plum significantly decreased serum levels of bone turnover markers including bone-specific alkaline phosphatase and tartrate-resistant acid phosphatase-5b. The findings of the present study confirmed the ability of dried plum in improving BMD in postmenopausal women in part due to suppressing the rate of bone turnover.

Aerobic exercise and whole-body vibration in offsetting bone loss in older adults.

Osteoporosis and its associated fractures are common complications of aging and most strategies to prevent and/or treat bone loss focused on antiresorptive medications. However, aerobic exercise (AEX) and/or whole-body vibration (WBV) might have beneficial effect on bone mass and provide an alternative approach to increase or maintain bone mineral density (BMD) and reduce the risk of fractures. The purpose of this paper was to investigate the potential benefits of AEX and WBV on BMD in older population and discuss the possible mechanisms of action. Several online databases were utilized and based on the available literature the consensus is that both AEX and WBV may increase spine and femoral BMD in older adults. Therefore, AEX and WBV could serve as nonpharmacological and complementary approaches to increasing/maintaining BMD. However, it is uncertain if noted effects could be permanent and further studies are needed to investigate sustainability of either type of the exercise.

Commentary: Aging America: meeting the needs of older Americans and the crisis in geriatrics.

The aging of the United States population will offer unprecedented challenges and opportunities for the health care system at large, and particularly medical education. In this issue of Academic Medicine, three articles provide opportunities for medical educators and others to ponder anew how we can address this so-called "age wave" as the baby boomers become senior boomers. Leipzig and colleagues describe their process for identifying 26 recommended geriatrics competencies for medical students, Reuben and colleagues examine the results of the first cohort of Reynolds Foundation geriatrics education grants, and Bernard and colleagues discuss the benefits of committing to developing departments of geriatrics at academic health centers. In addition, the recent Institute of Medicine (IOM) report, Retooling for an Aging America: Building the Health Care Workforce, highlights many of these issues. In this commentary, the authors discuss implications of selected articles from this issue and the IOM report, in hopes of provoking discussion and consideration of solutions to address the challenges faced by medical educators and by those who make public policy.

Strength and influence of geriatrics departments in academic health centers.

The United States is establishing new medical schools and increasing class size by 30% in response to the predicted increased needs of the baby boom generation, which will retire soon and live longer than prior generations. Society in general and the medical profession in particular are ill equipped to care for the special needs of the elderly. Since the early 1980s, departments of geriatric medicine have been developed in the United States. However, the prevailing U.S. system for the training of physicians in geriatrics is through sections, divisions, or institutes. This article reviews the advantages and disadvantages of departments of geriatrics, using case examples from three (University of Oklahoma College of Medicine, Florida State University College of Medicine, and University of Hawaii at Mãnoa John A. Burns School of Medicine) of the extant 11 medical schools in the United States with departments of geriatrics. Commonalities among the three departments include a seat at the planning table in academic life, equal treatment and collaboration with other departments in academic and research program development, and direct access to key decision makers and opportunities for negotiation for funds. Each department has outreach to all undergraduate medical students through its training program. All three departments were launched through the investment of significant resources obtained both internally and externally. The challenge for the future will be to definitively demonstrate the efficacy of the department model versus the more prevalent section, division, and institute approach to training physicians to care for the elderly.

Assistive technologies in the home.

Assistive technologies are critical to elders maintaining independence in the home. Adequate assessment of the patient's needs, the appropriateness of the device to that need, and the patient's motivation to use of a device is required for successful outcomes. A team approach is needed to ensure that devices are correctly prescribed, and the patient is taught how to use it effectively. A wide range of devices is available to support activities of daily living, mobility, home management, and safety. The use of personal computers is significantly expanding the possibility of independent living through support systems, monitoring systems, and information resources.

Guidelines abstracted from the Department of Veterans Affairs/Department of Defense clinical practice guideline for the management of stroke rehabilitation.

OBJECTIVES: To assist facilities in identifying those evidence-based processes of poststroke care that enhance measurable patient outcomes. The guideline(s) should be used by facilities (hospitals, subacute-care units and providers of long-term care) to implement a structured approach to improve rehabilitative practices and by clinicians to determine best interventions to achieve improved patient outcomes. OPTIONS: The guideline considers five elements of poststroke rehabilitation care: interdisciplinary teams; use of standardized assessments; intensity, timing, and duration of therapy; involvement of patients' families and caregivers in decision-making; and educational interventions for patients, families, and caregivers. Evidence, benefits, harms, and recommendations for each of the five designated elements and specific annotated recommendations for poststroke managements are presented separately. OUTCOMES: The overall guideline considers improvement in functional status measures as the primary outcome. Achieving community-dwelling status and preventing complications, death, and rehospitalization are also important outcomes. Costs are not specifically addressed. PARTICIPANTS: The Department of Veterans Affairs/Department of Defense (VA/DoD) Stroke Rehabilitation Working Group consisted of 28, largely VA and military hospital, representatives of medical and allied professions concerned with stroke diagnosis, management, and rehabilitation. Nine additional members with similar credentials served as the editorial committee. Technical consultation was contracted from ACS Federal Health Care, Inc., and the Center for Evidence-Based Practice, State University of New York-Upstate Medical University, Department of Family Medicine conducted evidence appraisal. Consensus was achieved over several years of facilitated group discussion and iterative evaluation of draft documents and supporting evidence. SPONSOR: The guideline was prepared under the auspices of the VA/DoD. No other source of support was identified in the document, or supporting documents.

Use of the Physician Orders for Life-Sustaining Treatment program in Oregon nursing facilities: beyond resuscitation status.

OBJECTIVES: Program was designed to communicate resident/surrogate treatment preferences in the form of medical orders. To assess statewide nursing facility use of the Physician Orders for Life-Sustaining Treatment (POLST) and to identify the patterns of orders documented on residents' POLST forms. DESIGN: Telephone survey; on-site POLST form review. SETTING: Oregon nursing facilities. PARTICIPANTS: One hundred forty-six nursing facilities in the telephone survey; 356 nursing facility residents aged 65 and older at seven nursing facilities in the POLST form review. MEASUREMENTS: A telephone survey; onsite POLST form reviews. RESULTS: In the telephone survey, 71% of facilities reported using the POLST program for at least half of their residents. In the POLST form review, do-not-resuscitate (DNR) orders were present on 88% of POLST forms. On forms indicating DNR, 77% reflected preferences for more than the lowest level of treatment in at least one other category. On POLST forms indicating orders to resuscitate, 47% reflected preferences for less than the highest level of treatment in at least one other category. The oldest old (> or = 85, n=167) were more likely than the young old (65-74, n=48) to have orders to limit resuscitation, medical treatment, and artificial nutrition and hydration. CONCLUSION: The POLST program is widely used in Oregon nursing facilities. A majority of individuals with DNR orders requested some other form of life-extending treatment, and advanced age was associated with orders to limit treatments.

Outcomes of pain in frail older adults with dementia.

OBJECTIVES: To describe the outcomes of pain in cognitively impaired older adults in a Program of All-inclusive Care for older people (PACE) setting and to determine whether pain and psychotropic drug use, behavioral disturbances, hospital, nursing facility, and emergency department use, or mortality increases with the level of pain reported. DESIGN: Retrospective review of an observational cohort of patients with dementia. SETTING: A first-generation PACE program located in Portland, Oregon. Patients with the diagnosis of dementia had been assessed for pain in a prior study. PARTICIPANTS: One hundred fifty-four cognitively impaired subjects. MEASUREMENTS: Standardized pain assessments were administered to cognitively impaired subjects between June and October 1998. After the pain assessment, information about mortality and healthcare use, including use of medication, was collected and analyzed. Subjects who reported moderate to severe pain were compared with demented subjects who reported no or mild pain. RESULTS: There were no differences in patient characteristics (age, sex, functional limitations, disruptive behaviors, and incontinence), medications (pain and psychotropic), use (hospital, nursing home, or emergency department visit), or mortality by level of pain alone or by levels of pain and dementia together. CONCLUSIONS: The study did not demonstrate that a single point-in-time measurement of pain in demented persons was associated with an increased rate of behavioral problems, narcotic use, or hospital or emergency department use over the following year. Prospective studies are needed that measure pain over time to determine more accurately the relationship between pain and negative outcomes in dementia.
