Gender-differences in disease distribution and outcome in hospitalized elderly: data from the REPOSI study.

BACKGROUND AND PURPOSE: Women live longer and outnumber men. On the other hand, older women develop more chronic diseases and conditions such as arthritis, osteoporosis and depression, leading to a greater number of years of living with disabilities. The aim of this study was to describe whether or not there are gender differences in the demographic profile, disease distribution and outcome in a population of hospitalized elderly people. METHODS: Retrospective observational study including all patients recruited for the REPOSI study in the year 2010. Analyses are referred to the whole group and gender categorization was applied. RESULTS: A total of 1380 hospitalized elderly subjects, 50.5% women and 49.5% men, were considered. Women were older than men, more often widow and living alone or in nursing homes. Disease distribution showed that malignancy, diabetes, coronary artery disease, chronic kidney disease and chronic obstructive pulmonary disease were more frequent in men, but hypertension, osteoarthritis, anemia and depression were more frequent in women. Severity and comorbidity indexes according to the Cumulative Illness Rating Scale (CIRS-s and CIRS-c) were higher in men, while cognitive impairment evaluated by the Short Blessed Test (SBT), mood disorders by the Geriatric Depression Scale (GDS) and disability in daily life measured by Barthel Index (BI) were worse in women. In-hospital and 3-month mortality rates were higher in men. CONCLUSIONS: Our study showed a gender dimorphism in the demographic and morbidity profiles of hospitalized elderly people, emphasizing once more the need for a personalized process of healthcare.

Sex differences in clinical presentation, severity and outcome of stroke: results from a hospital-based registry.

BACKGROUND AND PURPOSE: Sex related differences in cardiovascular disease and stroke are issues of increasing interest. The aim of this study was to evaluate for sex differences in clinical presentation, severity of stroke and outcome in a population of patients admitted to 4 public and 1 private hospitals in three different regions of Italy. METHODS: All hospital admissions for ischemic and haemorrhagic stroke (ICD-IX code 434 and 431 respectively) between January 1st and December 31st, 2011 at five different hospitals located in three different regions of Italy: Milan (North), Rome and Perugia (Center), and Palermo (South) have been recorded and sex-differences have been evaluated. RESULTS: A total of 1272 stroke patients were included in the analysis: 1152 ischemic and 120 haemorrhagic strokes, 567 women and 705 men. Compared to men, women were significantly older (mean age 75.2 SD 13.7 vs 71.5 SD 12.5 years, P<0.001) and their stroke severities at onset, measured by NIHSS, were also compared to men (10 SD 8 vs 8 SD 7, P<0.001). Female sex was associated with a worse functional prognosis measured by modified Rankin Scale score (mRS≥3), as well as in-hospital mortality, without reaching statistical significance. There were no observed significant differences between sexes regarding the number of patients treated with thrombolytic therapy. Analysis of the distribution of risk factors between sexes showed a prevalence of atrial fibrillation in women (29% vs 21%, P=0.003). CONCLUSIONS: Both stroke severity and functional outcome were worse in women.

Postural headache in a patient with Marfan's syndrome.

A 26-year-old man with Marfan's syndrome had postural headache. Brain MRI with gadolinium showed diffuse pachymeningeal enhancement. MRI myelography revealed bilateral multiple large meningeal diverticula at sacral nerve roots level. He was suspected to have spontaneous intracranial hypotension syndrome. Eight days later headache improved with bed rest and hydration. One month after the onset he was asymptomatic and 3 months later brain MRI showed no evidence of diffuse pachymeningeal enhancement. The 1-year follow-up revealed no neurological abnormalities. The intracranial hypotension syndrome likely resulted from a CSF leak from one of the meningeal diverticula. In conclusion patients with spinal meningeal diverticula (frequently seen in Marfan's syndrome) might be at increased risk of developing CSF leaks, possibly secondary to Valsalva maneuver or minor unrecognized trauma.

High stroke incidence in the prospective community-based L'Aquila registry (1994-1998). First year's results.

BACKGROUND AND PURPOSE: Changes in stroke incidence are likely to occur as a consequence of aging of the population, but evidence for this hypothesis is lacking. METHODS: A prospective community-based registry of first-ever strokes (1994 to 1998) classified according to the International Classification of Diseases, 9th Revision (ICD-9) was established in the L'Aquila district, central Italy, with a total population of 297,838 (1991 census). Patients were identified by active monitoring of multiple sources, including general practitioners. RESULTS: In 1994, 819 patients (398 men and 421 women; mean +/- SD age, 74.8 +/- 11.3 years) suffered from a first-ever stroke. Eighty-nine percent of the patients had neuroimaging studies of the brain and were reclassified with the recent Application of the International Classification of Diseases to Neurology (ICD-10 NA). The occurrence of subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction, and ill-defined events was 2.9%, 14.9%, 80.2%, and 2.0%, respectively. Crude annual incidence of first-ever stroke was 2.75/1000 (95% confidence interval [CI], 2.57 to 2.94) and 24.23/1000 (95% CI, 21.65 to 27.10) in patients older than 80 years. Incidence rates were higher in men and steeply increased with age. The standardized rate was 2.37/1000 for the Italian and 2.28/1000 for the European population. The 30-day case-fatality rate was 25.6% (95% CI, 22.8% to 28.7%). The occurrence of death, disability, and full recovery at 1 year was 36.9%, 38.9%, and 24.2%, respectively. No differences were found in stroke incidence and case-fatality according to income and urban or rural residences. CONCLUSIONS: In our population-based study, we found a high stroke incidence notably in the older age subgroups, suggesting that rather than declining, stroke is only being postponed until later in life.

Geomagnetic activity, humidity, temperature and headache: is there any correlation?

Meterological factors influence several biological functions. Geomagnetic activity (GMA) can be considered a trigger factor of migraine attacks. We studied the possible relationship between 40 migraine patients and some meteorological factors: humidity, temperature and geomagnetic activity in particular. All frequency changes of geomagnetic activity, temperature and humidity values are recorded daily. The study was performed from March to June 1988 over a geographically small area in order to avoid climatic and environmental influences. Our results indicate a significant correlation between geomagnetic activity and migraine attack frequency. Controversial opinions concerning the modalities of data collection and the possible relationships between environment and headache raise the need of further studies.
