Hyperventilation in patients who have sustained myocardial infarction after a work injury.

Patients who present with acute myocardial infarction after a work injury (AMI-WI) often report symptoms consistent with chronic hyperventilation which date back as far as the work injury itself, rather than to the AMI. The aim of the study was to test the hypothesis that hyperventilation significantly contributes to the symptoms of AMI-WI patients. The prevalence of hyperventilation was assessed by clinical capnography in 12 AMI-WI patients, 20 normal controls, 15 AMI patients whose AMI was conventional and not subsequent to a work injury (AMI-C) and 14 patients with post-traumatic stress disorder (PTSD). End-tidal carbon dioxide partial pressure (P(et)CO2) was measured at rest, after 1 min hyperventilation (FHPT), after recall of the relevant stressor (Think) and when the breathing was felt to be normal (MBIN). P(et)CO2 levels after FHPT were: 29.0 +/- 1.5 (mean +/- SD) mmHg for AMI-WI; 26.7 +/- 1.9 mmHg for PTSD; 32.1 +/- 4.1 mmHg for AMI-C and 33.7 +/- 1.4 mmHg for the controls (P < 0.05 and P < 0.01 for AMI-WI and PTSD, respectively, versus controls). After Think, the levels were 25.8 +/- 1.6 mmHg for AMI-WI, 24.6 +/- 1.4 mmHg for PTSD, 31.2 +/- 4.1 mmHg for AMI-C and 31.2 +/- 1.5 mmHg for normals (P < 0.05 and P < 0.01 for AMI-WI and PTSD, respectively, versus controls). For MBIN, values of P(et)CO2 were 26.8 +/- 1.7 mmHg and 26.7 +/- 1.5 mmHg for AMI-WI and PTSD versus 33.8 +/- 1.2 mmHg for normals, (P < 0.01 for both versus controls).(ABSTRACT TRUNCATED AT 250 WORDS)     

Osteoporosis and the risk of hip fracture

The incidence of cervical and intertrochanteric proximal femur fractures at various levels of cervical and intertrochanteric bone mineral density, respectively, was estimated by using population-based data from ongoing studies of osteoporosis and fractures among women residing in Rochester, Minnesota. Hip fractures were uncommon among women with femoral bone density greater than or equal to 1.0 g/cm2, but their frequency increased as bone density declined below that point at both femoral sites. The incidence of cervical femur fractures was estimated at 8.3 per 1,000 person-years among women with cervical bone density less than 0.6 g/cm2, while the estimated incidence of intertrochanteric femur fractures reached 16.6 per 1,000 person-years among those with intertrochanteric bone density less than 0.6 g/cm2. This new approach to the assessment of fracture risk from bone mineral density measurements indicates that osteoporosis is an important underlying cause of hip fractures.     

Psychosocial assessment of patients who have undergone inpatient cancer rehabilitation

This study summarized the social work services provided in an acute inpatient cancer rehabilitation program. Reviewed were 49 consecutive social worker assessments from February 2003 to March 2003. The social worker was consulted mostly for discharge planning (40/49, 82%) and helping patients cope (23/49, 47%). Sixty-seven percent of the patients (33/49) were coping well. Sixty-five percent of patients (32/49) had an identified caregiver. Most patients planned to go home (33/49, 67%) after their discharge. Interventions provided by the social worker included counseling (100% of patients/ families), referral to financial resources (24/49, 49%) and transportation services (21/49, 43%), and other resources (37/49, 76%). Age, gender, and identified caregiver did not show significant association with the coping status or referrals. The social worker is important in assessing cancer patients' coping and providing support.     

Subsequent hip fracture among older adults.

Subsequent hip fracture among the 368 Longitudinal Study on Aging respondents who fractured their hips from 1984 through 1991 was prospectively examined. Case-by-case review of the billing records indicated that 27 subsequent hip fractures occurred, for a rate of 1 every 33.8 person-years. Multivariable proportional hazard regression revealed that increased risks of subsequent hip fracture were associated with poor perceived health status and dizziness.     

Hyponatraemia in hip fracture patients

We performed a retrospective review of hyponatraemia in patients with hip fractures, before and after surgery. All patients admitted with fractures of the neck of femur who had a surgical intervention to deal with the fracture were included. Results were determined using two definitions for hyponatraemia. The incidence of pre-operative and post-operative hyponatraemia were both 2.8% if hyponatraemia was defined as [Na] < 130 mmol/l. No cases of hyponatraemia were found pre-operatively when hyponatraemia was defined as [Na] < 125 mmol/l. Using this definition the post operative incidence of hyponatraemia was 0.93%. The incidence of hyponatraemia in this group of patients is small. However the potentially severe affects of hyponatraemia warrant close monitoring of these patients and the establishment of methods to prevent this problem from occurring.     

Expectations about outcome following hip fracture among older people

This paper reports on two studies, based on ethnographic interviews, of expectations about recovery from hip fracture. Interviewed were community residing elderly who had not experienced a hip fracture and 11 hospitalized hip fracture patients aged 59 to 85 years. Community elderly foresaw permanent impairment and social death. Hip fracture patients altered their expectations in response to observed progress and communications from health professionals. Perceptions of their own functional health also shaped these expectations. Several ways are suggested for social workers to use their observations of patients' expectations, and how they are constructing them, to guide interventions.     

Changes in functional status attributable to hip fracture: a comparison of hip fracture patients to community-dwelling aged

Disability attributable to hip fracture regarding activities of daily living was evaluated by comparing 594 hip fracture patients entering eight hospitals in Baltimore, Maryland, in 1990-1991 with community-dwelling aged from the Established Populations for Epidemiologic Studies of the Elderly (EPESE) cohort matched on age, sex, and walking ability. Subjects were assessed at baseline (prefracture report for patients), 12 months, and 24 months. At baseline, 26% of both groups had walking disability, 12-14% had transferring disability, and 6-8% evidenced grooming disability. At 12 and 24 months, about 50% of hip fracture patients were walking disabled compared with 21-29% of EPESE respondents after the authors controlled for age, sex, comorbidities, and functional status (excess disability attributable to hip fracture, i.e., attributable disability, of 26 additional cases of disability per 100 persons in the hip fracture cohort during follow-up). Likewise, hip fracture patients experienced more disability regarding transferring (38-39% vs. 10-18%; attributable disability, approximately 22 cases per 100 persons) and grooming (17-19% vs. 7-15%; attributable disability, approximately six cases per 100 persons). Thus, results showed that hip fracture patients had substantially more activities of daily living disability than that explained by aging over 24 months.     

Estimation of lean body weight in older women with hip fracture

Objective

Lean body weight (LBW) decreases with age while total body fat increases, resulting in altered drug pharmacokinetics. A semi-mechanistic equation estimating LBW using height, weight and sex has been developed for potential use across a wide range of body compositions. The aim of this study was to determine the ability of the LBW equation to estimate dual energy x-ray absorptiometry-derived fat free mass (FFM_DXA) in a population of older women with recent hip fracture.

Methods

Baseline, four and 12 month data obtained from 23 women enrolled in the Sarcopenia and Hip Fracture study were pooled to give 58 measurements. LBW was estimated using the equation: $LBW(kg) = \frac{{9270 \times Wt}} {{8780 + (244 \times BMI)}} $ Body composition was classified as: ??normal?? (BMI <25kg/m² and not sarcopenic), ??overweight-obese?? (BMI >25kg/m² and not sarcopenic), ??sarcopenic?? (sarcopenic and BMI <25kg/m²), or ??sarcopenic-obese?? (sarcopenic and BMI >25kg/m²). The ability of the LBW equation to predict FFM_DXA was determined graphically using Bland-Altman plots and quantitatively using the method of Sheiner and Beal.

Results

The mean ± SD age of female participants women was 83±7 years (n=23). Sarcopenia was frequently observed (65.2%). Bland-Altman plots demonstrated an underestimation by the LBW equation compared to FFM_DXA. The bias (95% CI) and precision (95% CI) calculated using the method of Sheiner and Beal was 0.5kg (?0.7, 1.66kg) and 4.4kg (?3.7, 12.4kg) respectively for pooled data.

Conclusion

This equation can be used to easily calculate LBW. When compared to FFM_DXA, the LBW equation resulted in a small underestimation on average in this population of women with recent hip fracture. The degree of bias may not be clinically important although further studies of larger heterogeneous cohorts are needed to investigate and potentially improve the accuracy of this predictive equation in larger clinical cohorts.     

Mineral deficiency in patients who have undergone gastrectomy

OBJECTIVE: We investigated the nature of nutritional deficiencies that arose in gastrectomy patients by comparing mineral absorption in patients with total and subtotal gastrectomies before and after operation. METHODS: Levels of nutritional, micro, and toxic minerals were measured in a subject group of 20 patients with gastric cancer. Patients were grouped according to total versus subtotal gastrectomy. Hair tissue was collected 3 mo before and after operation from each patient. Tissue was analyzed by atomic absorption spectroscopy for levels of various minerals. Mineral ratios were computed to display changes in mineral levels, and results were statistically analyzed with SPSS 10.0 to obtain a measurement distribution. The t test was used to determine any significant difference between patients before and after operation. RESULTS: In the preoperation test, sodium, potassium and iron levels were higher than normal, whereas boron and molybdenum levels were lower than normal. Although sodium levels decreased significantly after surgery, molybdenum, cadmium, and lead levels increased significantly. Potassium decreased slightly in the subtotal gastrectomy group, but increased significantly in the total gastrectomy group. However, there was no change between before and after surgery for most minerals. CONCLUSION: In the short term, gastrectomy does not seem to affect the levels of most minerals in the body. However, changes in sodium levels indicate that gastrectomy affects sodium absorbency in gastric cancer patients. Potassium levels increased significantly in patients who received total gastrectomies; this may also be an area that nutritional treatment should focus on.     

Characteristics of older pedestrians who have difficulty crossing the street.

OBJECTIVES: This study examined the sociodemographic and health characteristics and problems of older pedestrians. METHODS: Interviews and assessments were conducted with 1249 enrollees aged 72 or older from the New Haven, Conn, community of the Established Populations for Epidemiologic Studies of the Elderly who agreed to participate in a seventh follow-up. RESULTS: Approximately 11% of the New Haven residents reported difficulty crossing the street. Older pedestrians needing help in one or more activities of daily living were more than 10 times as likely as others, and those with the slowest walking speeds were nearly 3 times as likely as others, to report difficulty crossing the street. Fewer than 1% of these pedestrians aged 72 or older had a normal walking speed sufficient to cross the street in the time typically allotted at signalized intersections (1.22 m/sec). CONCLUSIONS: Crossing times at signalized intersectíons in areas with large populations of elders should be extended, and the recommended walking speed for timing signalized crossings should be modified to reflect the range of abilities among older pedestrians.     

Quality of life in osteoporotic patients with hip fracture and without fracture

The aim of this study was to analyse the quality of life in osteoporotic patients with hip fracture and those without fractures. The study included postmenopausal women, 35 with hip fracture and 33 without fractures. The control group included 44 age-matched healthy women. Osteoporosis Quality of Life Questionnaire was used to assess the health-related quality of life (HRQL). Patients with hip fracture had significantly lower scores in symptoms, physical function and leisure (P < 0.05), than patients without fractures. Both groups of patients had significantly lower scores than controls in all domains except Leisure. Analysing several health and social factors that could influence HRQL, we found that bone mass in spine and femoral neck significantly correlated with HRQL. Since patients with osteoporosis usually have no symptoms before fracture, early diagnosis and the treatment of the disease are of key importance to the quality of life in these patients.     

Patient-reported outcome measures in older people with hip fracture: a systematic review of quality and acceptability

Purpose

Hip fracture is the most common serious injury of older people, often resulting in reduced mobility and loss of independence. However, guidance for the use of patient-reported outcome measures (PROMs) does not exist: we describe the first review to apply internationally endorsed criteria in support of PROM quality and acceptability in this group, and make recommendations for future applications.

Methods

Systematic literature searches of major databases (1980–2015) to identify published evidence of the application and quality of clearly defined measures. Evidence of measurement and practical properties, and the extent of active patient involvement, was sought. Study and PROM quality was assessed against recommended criteria.

Results

Seventy-one articles relating to 28 PROMs (Generic n = 12; Specific n = 16) were included. The SF-36 (v1) and EuroQoL EQ-5D 3L were the most widely evaluated measures with acceptable evidence of measurement properties, but limited evaluations of practical properties or relevance to this group. Evidence was mostly limited for the remaining measures. Hypothesized associations between variables were infrequently evaluated. Evidence of data quality, test–retest reliability, responsiveness, interpretation, acceptability and feasibility was also limited. Active patient involvement in PROM development or evaluation was not reported. There was limited evaluation of proxy completions.

Conclusions

The paucity of robust evaluations is disappointing and prevents clear recommendations for PROM-based assessment. Further research must urgently seek to identify which outcomes really matter to this group. Future PROM selection must be underpinned by research which focuses on methodological quality, including issues of acceptability, relevance, feasibility of application, and proxy completion, whilst seeking to actively incorporate the perspective of patients and their advocates.

     

Mini nutritional assessment and mortality after hip fracture surgery in the elderly

Background

Hip fracture surgery in elderly patients is associated with a poor postoperative outcome and a high mortality. Malnutrition is a frequent problem in elderly patients and may be associated with mortality after hip fracture surgery. The Mini Nutritional Assessment (MNA) is a valuable tool to identify malnourished patients and those at risk for malnutrition.

Objective

To evaluate the association between the preoperative MNA score and mortality after surgery for hip fractures in elderly patients.

Methods

Patients with a hip fracture and an indication for surgery were included in our study. This study was part of a randomized trial on the effect of taurine on postoperative outcome in elderly hip fracture patients. The MNA was assessed on admission before surgery. Length of stay, postoperative complications and mortality were documented. The association of the MNA score on postoperative outcome and mortality was analyzed using Cox regression analysis.

Results

The one-year survival rate in 226 elderly hip fracture patients was 79%. In-hospital mortality rates and 1-year mortality were 27% and 46% in malnourished patients, 12% and 26% in patients at risk for malnutrition and 7% and 17% in well-nourished patients as assessed by MNA.

Conclusion

Preoperative malnutrition measured by the MNA is associated with mortality in elderly hip fracture patients.
