Estate management: when reality stifles ambition

Health service buildings and lands make up an estate which must be managed in such a way that the future does not suffer from the neglect of the present. Looking to the NHS as it is likely to be in the 1980s, Gordon Brooke, regional works officer, Mersey RHA, suggests an end to a system in which capital is a 'free good' and districts under financial pressure have little incentive to preserve the value of their estates.     

Neuropsychological functioning and sleep patterns in the elderly.

OBJECTIVE: To discover whether reported sleep-wake disturbances in the elderly (more frequent nocturnal awakenings, earlier waking and more day time naps) are associated with neuropsychological dysfunction. DESIGN AND SETTING: A sample of 124 residents of a retirement village complex were interviewed about their sleep patterns and given neuropsychological assessments. Reported sleep-wake difficulties were combined to form two variables, "night sleep" and "day sleep". Additional sleep variables analysed were reported sleep duration and time of wakening. Principal components analysis of the neuropsychological test scores yielded four factors: "general ability", "memory", "motor", and "cerebral efficiency". MAIN OUTCOME MEASURES: A correlation analysis was performed for sleep variables, neuropsychological factors and age, mood scale and scores on indices of participation in physical and passive activities. RESULTS: There was no correlation between "night sleep" and the factor scores derived from the neuropsychological tests. "Day sleep" was correlated with "cerebral efficiency" only. Age was correlated with the "memory" and "motor" factors, the latter also being associated with participation in physical activities. CONCLUSION: Night sleep problems are not associated with neuropsychological deficits in a non-clinic population.     

Assessment issues involving the families of trauma victims

This paper reviews the empirical literature on the clinically significant problems found within families containing a member with post-traumatic stress disorder. Recommendations are made regarding specific instruments that can be useful for evaluating marital and familial adjustment. Assessment issues concerning the need to weigh historical relationship factors vis-á-vis the influences of a traumatized family member are discussed. A multiple-gating model is presented for assessing different aspects of family dysfunction, and suggestions for future research and clinical directions are offered.     

Computed tomography as an adjunct to ultrasound in the diagnosis of acute acalculous cholecystitis

The sonographic and computed tomographic (CT) findings were reviewed in 17 patients with acute acalculous cholecystitis (AAC) over a 6-year period from 1984 to 1989. Of the six patients in whom both ultrasound and CT were performed, CT revealed marked gallbladder (GB) wall abnormalities, including perforation, and pericholecystic fluid collections in five patients not demonstrated by sonography. Of the total group, five patients had GB wall thicknesses of 3 mm (normal) at pathologic examination, which demonstrated a spectrum of disease ranging from acute hemorrhagic/necrotizing, to gangrenous acalculous cholecystitis with perforation. Sonography was falsely negative or significantly underestimated the severity of AAC in seven of the 13 patients examined by sonography. CT because of its superior ability to assess pericholecystic inflammation may provide additional diagnostic information even after a thorough sonographic study in cases of AAC.     

Foetal cystic abdominal masses

Foetal abdominal cysts are frequently found on routine antenatal ultrasound. Various sonographic features might help in their differential diagnosis. However, a definitive diagnosis is often not made until postnatal life, and detection of an intra‐abdominal cyst antenatally rarely alters obstetric management. A review of possible causes of a foetal abdominal cyst is presented.     

Cost-utility analysis of screening intervals for diabetic retinopathy in patients with type 2 diabetes mellitus

CONTEXT: Annual eye screening for patients with diabetes mellitus is frequently proposed as a measure of quality of care. However, the benefit of annual vs less frequent screening intervals has not been well evaluated, especially for low-risk patients. OBJECTIVE: To examine the marginal cost-effectiveness of various screening intervals for eye disease in patients with type 2 diabetes, stratified by age and level of glycemic control. DESIGN: Markov cost-effectiveness model. SETTING AND PARTICIPANTS: Hypothetical patients based on the US population of diabetic patients older than 40 years from the Third National Health and Nutrition Examination Survey. MAIN OUTCOME MEASURES: Patient time spent blind, quality-adjusted life-years (QALYs), and costs of annual vs less frequent screening compared by age and level of hemoglobin A1c. RESULTS: Retinal screening in patients with type 2 diabetes is an effective intervention; however, the risk reduction varies dramatically by age and level of glycemic control. On average, a high-risk patient who is aged 45 years and has a hemoglobin A1c level of 11% gains 21 days of sight when screened annually as opposed to every third year, while a low-risk patient who is aged 65 years and has a hemoglobin A1c level of 7% gains an average of 3 days of sight. The marginal cost-effectiveness of screening annually vs every other year also varies; patients in the high-risk group cost an additional $40530 per QALY gained, while those in the low-risk group cost an additional $211570 per QALY gained. In the US population, retinal screening annually vs every other year for patients with type 2 diabetes costs $107510 per QALY gained, while screening every other year vs every third year costs $49760 per QALY gained. CONCLUSIONS: Annual retinal screening for all patients with type 2 diabetes without previously detected retinopathy may not be warranted on the basis of cost-effectiveness, and tailoring recommendations to individual circumstances may be preferable. Organizations evaluating quality of care should consider costs and benefits carefully before setting universal standards.     

The Impact of Diabetes on Workforce Participation: Results from a National Household Sample

Objective. Diabetes is a highly prevalent condition that results in substantial morbidity and premature mortality. We investigated how diabetes-associated mortality, disability, early retirement, and work absenteeism impacts workforce participation.
Data Source. We used the Health and Retirement Study (HRS), a national household sample of adults aged 51–61 in 1992, as a data source.
Study Design. We conducted cross-sectional analyses on the baseline HRS data, and longitudinal analyses using data from eight years of follow-up. We used two-part regression models to estimate the adjusted impact of diabetes on workforce participation, and then estimated the economic impact of diabetes-related losses in productivity.
Principal Findings. Diabetes is a significant predictor of lost productivity. The incremental lost income due to diabetes by 1992 was $60.0 billion over an average diabetes duration of 9.7 years. From 1992 to 2000, diabetes was responsible for $4.4 billion in lost income due to early retirement, $0.5 billion due to increased sick days, $31.7 billion due to disability, and $22.0 billion in lost income due to premature mortality, for a total of $58.6 billion dollars in lost productivity, or $7.3 billion per year.
Conclusions. In the U.S. population of adults born between 1931 and 1941, diabetes is associated with a profound negative impact on economic productivity. By 1992, an estimated $60 billion in lost productivity was associated with diabetes; additional annual losses averaged $7.3 billion over the next eight years, totaling about $120 billion by the year 2000. Given the rising prevalence of diabetes, these costs are likely to increase substantially unless countered by better public health or medical interventions.     

Bioterrorism risk perceptions and educational needs of public health professionals before and after September 11, 2001: a national needs assessment survey.

The study objectives were to compare local public health professionals' bioterrorism risk perceptions, the extent of bioterrorism preparedness training, and to describe preferred methods for delivery of preparedness education in the United States. National needs assessments were conducted via a mailed survey to 3,074 local public health departments in October 2000 and November 2001. Compared to a survey conducted in October 2000, the perceived risk of a bioterrorism attack in the United States increased dramatically after September 11 (p < 0.0001); however, 57% of respondents believed one was unlikely to occur within their own community. Public health professionals perceive their own communities to be at low risk for a bioterrorism event. Ongoing, updated, standardized bioterrorism preparedness education is needed.     

IRIS study: a phase II study of the steroid sulfatase inhibitor Irosustat when added to an aromatase inhibitor in ER-positive breast cancer patients

Purpose

High mammographic breast density (BD) is a strong risk factor of breast cancer; however, little is known in women under 40 years of age. Recently, dual-energy X-ray Absorptiometry (DXA) has been developed as a low-dose method to measure BD in young populations. Thus, our aims were to describe BD in relation to risk factors in Chilean women under 40 years old and to explore the equivalence of DXA to mammography for the measurement of BD.

Methods

We selected 192 premenopausal Chilean female participants of the DERCAM study for whom we have anthropometric, sociodemographic, and gyneco-obstetric data. The subjects received both digital mammograms (Hologic) and breast DXA scans (GE iDXA). Mammographic BD was estimated using a fully automated commercial method (VOLPARA^®) and BI-RADS. Breast DXA scans were performed using a standardized protocol and the % fibroglandular volume (%FGV) was estimated considering a two-compartment model of adipose and fibroglandular tissue.

Results

The mean age was 37 years (SD = 6.5) and 31.6% of the subjects were obese. The median %FGV and absolute FGV (AFGV) measured by DXA were 9% and 198.1 cm³ and for VOLPARA^®, 8.6% and 58.0 cm³, respectively. The precision for %FGV after reposition was 2.8%. The correlation coefficients for %FGV, AFGV, and breast volume between DXA and mammography were over 0.7. Age and body mass index (BMI) were inversely associated with %FGV, and BMI was positively related to AFGV as estimated with DXA or mammography. We did not observe an association with gyneco-obstetric characteristics, education, and %FGV and AFGV; smoking was only associated with AFGV as measured by VOLPARA^®.

Conclusions

DXA is an alternative method to measure volumetric BD; thus, it could be used to continuously monitor BD in adult women in follow-up studies or to assess BD in young women.
