Background: Elderly patients with hip fracture have a 5 to 8 fold increased risk of death during the months following surgery. We tested the hypothesis that early geriatric management of these patients focused on co-morbidities and rehabilitation improved long term mortality., Methods and Findings: In a cohort study over a 6 year period, we compared patients aged >70 years with hip fracture admitted to orthopedic versus geriatric departments in a time series analysis corresponding to the creation of a dedicated geriatric unit. Co-morbidities were assessed using the Cumulative Illness Rating Scale (CIRS). Each cohort was compared to matched cohorts extracted from a national registry (n = 51,275) to validate the observed results. Main outcome measure was 6-month mortality. We included 131 patients in the orthopedic cohort and 203 in the geriatric cohort. Co-morbidities were more frequent in the geriatric cohort (median CIRS: 8 vs 5, P<0.001). In the geriatric cohort, the proportion of patients who never walked again decreased (6% versus 22%, P<0.001). At 6 months, re-admission (14% versus 29%, P = 0.007) and mortality (15% versus 24%, P = 0.04) were decreased. When co-morbidities were taken into account, the risk ratio of death at 6 months was reduced (0.43, 95%CI 0.25 to 0.73, P = 0.002). Using matched cohorts, the average treatment effects on the treated associated to early geriatric management indicated a reduction in hospital mortality (-63%; 95% CI: -92% to -6%, P = 0.006)., Conclusions: Early admission to a dedicated geriatric unit improved 6-month mortality and morbidity in elderly patients with hip fracture.

Background: How well the motor symptoms assessed by the motor section of the Unified Parkinson Disease Rating Scale (UPDRS3) reflect the neuronal loss observed in the substantia nigra is not known., Objective: To study the relationships among the motor symptoms assessed by the UPDRS3, Lewy body-associated neuronal loss in the substantia nigra, and duration of disease., Design: Longitudinal, prospective, clinicopathological study., Setting: Long-term care facility of a university hospital., Patients: Eighteen elderly patients with a parkinsonian syndrome, studied prospectively but selected post mortem on the basis of the presence of Lewy bodies, and 5 age-matched control subjects., Methods: One map of a section of the substantia nigra, indicating the location of all the nucleolated neuronal profiles, was drawn for each case. Neuronal density was estimated using a tessellation method. The relationship between time and neuronal loss and between neuronal loss and motor symptoms (assessed by the UPDRS3) was studied by means of regression analysis, using linear and exponential models., Results: The neuronal density was linearly linked with the UPDRS3 score (r = -0.83 [P<.001]). Each point added to the UPDRS3 score corresponded to an estimated loss of 25 neurons/mm(3). The density of neuronal profiles in the substantia nigra decreased exponentially with time (r = -0.73 [P<.001]). Extrapolation of the curve suggested a presymptomatic phase of 5 years., Conclusion: The UPDRS3 score is linearly linked to neuronal density, which, in Lewy body diseases, decreases exponentially with time at a similar pace in this series of elderly patients and in the younger patients described in the literature.

Objectives: To identify independent risk factors of symptomatic deep vein thrombosis (DVT) in geriatric inpatients and to define high-risk patients likely to benefit from preventive treatment., Design: Hospital-based case-control multicenter study with prospective data collection., Settings: Geriatric university hospitals with long-, intermediate-, and short-term care facilities., Participants: All patients aged 65 and older in 19 geriatric departments were submitted to clinical surveillance over a 16-month period., Measurements: Twenty-three potential risk factors of phlebitis were screened for. Comparison using logistic regression of 310 consecutive patients with symptomatic DVT versus 310 randomly selected controls was performed. The risk for symptomatic DVT in geriatrics was then scored from the clinical risk factors identified using multivariate analysis. This score is defined by the sum of the odds ratio (OR) of each risk factor present., Results: Six factors were identified as independently related to the development of DVT: restriction of mobility (from OR=1.73, limited mobility without immobilization, to OR=5.64, bedridden during <15 days), aged 75 and older (OR=1.5/10 years), history of DVT or pulmonary embolism (OR=3.38), acute heart failure (OR=2.52), chronic edema of the lower limbs (OR=2.51), and paresis or paralysis of a lower limb (OR=2.06). The defined score of 8 or higher corresponded to an 88.7% probability of having symptomatic DVT., Conclusion: Treatments to prevent symptomatic DVT in hospitalized elderly should be evaluated on patients with these factors.

Objectives: The purpose of this work was to search for prognostic factors after percutaneous endoscopic gastrostomy (PEG) for enteral nutrition in geriatric patients by studying complications, nutritional benefits, and impact on quality of life., Methods: In this prospective study, 59 elderly patients referred for PEG were followed for 1 year or until tube removal or death. Complications, tolerance to enteral nutrition, nutritional status, infection, bedsores and quality of life were assessed by a questionnaire at tube insertion, at 1 month and every 3 months. Multivariate analysis was performed to look for factors predictive of early mortality before one month., Results: Insertion of the PEG tube was always successful. Pneumonia in the week before tube insertion was predictive of early mortality (odds-ratio: 8.77 [1.63-47.2], P=0.01). Thirty-day mortality was 25%, but was never related to PEG tube insertion. During follow up, no local complication was observed and enteral feeding was well tolerated. After 3 months, serum albumin and prealbumin levels increased (P<0.001). There were fewer infections (P<0.001) and bedsores remained unchanged. Quality-of-life scores were not modified. At one year, the PEG tube was removed in 16 patients who resumed normal oral nutrition, and 6 other patients were able to return to their home., Conclusion: In a cohort of aged institutionalized patients, PEG for enteral nutrition was well tolerated and not definitive in more than one-quarter of them. Active lung infection is a risk factor of early mortality.

A sixty-four year-old woman was admitted for chronic diarrhea with severe weight loss. Investigations showed hepatomegaly, positive serologic tests for syphilis, and nephrotic syndrome with proteinuria. Anasarca occurred and the patient died shortly after admission. Necropsy showed sclero-gummatous hepatic syphilis, generalized amyloïdosis and ulcerative colitis. These last two manifestations and their association with tertiary stage syphilis are discussed.
