Becoming Godless: Heidegger's Nietzsche and the Eternal Return

Nietzsches concept of eternal return best exemplifies his anti-theological thought, but it is often misread as either classical physics or a thought experiment. Insofar as Anglo-American and analytic interpretations reject eternal returns cosmology, their ethical implications are minimized. By contrast, Heideggers synthesized cosmological and ethical reading is shown to be more normatively significant in framing Nietzsches philosophy as radical atheism. However, it is also shown that Heidegger limits Nietzsches radicalness by approaching eternal return as the notion that being as a whole returns identically. To that end, it is next argued that Heideggers explication of the cosmology as an ethical projection is superior to scientific interpretations in analytic and Anglo-American readings, but also that Heidegger partially misreads eternal returns cosmology. It is therefore finally demonstrated that Nietzsches cosmology actually rejects that an identical state of being returns. This finally allows for the most profound ethical implications in Nietzsches philosophy

The key points for treatment of Parkinsonism in older persons

Signs and symptoms of Parkinsonism have a high prevalence in older persons. Parkinsonism is associated with negative outcomes in the elderly and there is still uncertainty about when and how to start levodopa in these conditions. The diagnosis of idiopathic Parkinson disease is often not pursued in the oldest old. The coexistence of both motor and cognitive impairment is the strongest factor limiting the initiation of treatment with levodopa and/or dopamine agonists in a geriatric setting, given the possibility of producing psychotic symptoms, such as visual hallucinations. It seems reasonable to perform at least one attempt to administer levodopa in older persons with parkinsonism, especially when symptoms and motility disorders are evident, in order to try to obtain an improvement in walking speed and balance. Important signs that should guide treatment for Parkinsonism in older persons are the presence of line-pipe rigidity and cogwheel rigidity

Relationship between comprehensive geriatric assessment and amyloid PET in older persons with MCI

Background: The association between amyloid deposition and cognitive, behavioral and physical performance in mild cognitive impairment (MCI) due to Alzheimer’s disease (AD) has been poorly investigated, especially in older persons. Methods: We studied the in vivo correlation between the amyloid deposition at Positron Emission Tomography (amyloid-PET) and the presence of memory loss, reduced executive function, neuropsychiatric symptoms and physical performance in older persons with MCI. Amyloid-PET was performed with 18F-flutemetamol and quantitatively analyzed. Results: We evaluated 48 subjects, 21 men and 27 women. We performed in each patient a comprehensive geriatric assessment (CGA) including Mini Mental State Examination (MMSE), Clock Drawing Test (CDT), Activity Daily Living (ADL), Instrumental Activity of Daily Living (IADL), Neuropsychiatric inventory (NPI) questionnaire, 15 Geriatric Depression Scale (GDS), Short Physical Performance Battery (SPPB) and Hand Grip strength. Then, each patient underwent amyloid-PET. Mean age of the enrolled subjects was 74.6 ± 7.8 years. All of these subjects showed preserved cognitive function at MMSE > 24, while 29 of 48 subjects (61.0%) had altered CDT. Mean NPI score was 6.9 ± 5.9. The mean value of SPPB score was 9.0 ± 2.6, while the average muscle strength of the upper extremities measured by hand grip was 25.6 ± 7.7 Kg. CT/MRI images showed cortical atrophic changes in 26 of the 48 examined subjects (54.0%), while cerebrovascular modifications were present in 31 subjects (64.5%). Pathological burden of amyloid deposits was detected in 25 of 48 (52.0%) patients with a mean value of global z-score of 2.8 (subjects defined as MCI due to AD). After stratifying subjects in subclasses of clinical alterations, more probability of pathological amyloid deposition was found in subjects with impaired CDT and higher NPI score (O.R. = 3.45 [1.01–11.2], p = 0.04), with both impaired CDT and low physical performance (O.R. = 5.80 [1.04–32.2], p = 0.04), with altered CDT and high NPI score (O.R. = 7.98 [1.38–46.0], p = 0.02), and finally in those subjects with altered CDT, high NPI and low physical performance (O.R. = 5.80 [1.05–32.2], p = 0.04). Conclusion: Our findings support the recent hypothesis that amyloid deposition could be associated with multiple cerebral dysfunction, mainly affecting executive, behavioral and motor abilities

The risk of dysphagia is associated with malnutrition and poor functional outcomes in a large population of outpatient older individuals.

Summary Oropharyngeal dysphagia (OD) is a widespread clinical condition among older adults. Although it represents a risk factor for malnutrition, dehydration and aspiration pneumonia, its assessment and contribution to functional decline is often ignored. The aim of the present study was to estimate the prevalence of OD in a large population of non-institutionalized older people and to evaluate its relationship with malnutrition and physical function. 10-item Eating Assessment Tool (EAT-10) and Mini Nutritional Assessment Short Form (MNA-SF) were used to identify the risk of dysphagia and malnutrition. Short Physical Performance Battery (SPPB) and hand-grip strength were used as functional endpoints. The relationship between risk of dysphagia and functional outcomes was tested in a multivariate regression analysis adjusted for age and sex (Model 1) and for other confounders including Mini Mental State Examination (MMSE) and polypharmacy (Model 2). Mean age of 773 subjects (61.3% female) was 81.97 years. The percentage of participants at risk of dysphagia (EAT ≥ 3) was 30.1%, 37.8% of subjects was malnourished (MNA-S

Chest ultrasound in italian geriatric wards: Use, applications and clinicians’ attitudes

Background and aims. Bedside chest ultrasound has emerged as a versatile and accurate diagnostic tool for the management of respiratory conditions in several clinical settings, integrating traditional imaging. The current utilization of this technique in geriatric hospital wards is still unknown. Our aim was to assess availability, uses and applications of chest ultrasonography in a convenience sample of 25 Italian geriatric wards. Methods. A questionnaire, based on the current literature state-of-the-art, was e-mailed to head doctors of geriatric wards of Italian hospitals. The questionnaire explored ultrasound equipment availability, practice of chest ultrasound, expertise of ward physicians, clinical indications, and perceived impact on patient care. Results. Ultrasound equipment was available in 92% of wards, and chest ultrasound was performed in 82% of cases. Among the wards where chest ultrasound was performed, it was considered as routine assessment in only 52% of cases, mainly for diagnosis of pleural effusions (95%) and acute heart failure (89%), assessment of volemic state (79%), and assistance to invasive procedures (79%). It was used in emergency/ urgency assessment of acute dyspnea in only 53% of cases. In most wards, only three or less physicians were able to perform chest ultrasound. In 53% of cases, head doctors declared that they perceived benefits of chest ultrasound in patient care in only selected cases. Conclusions. Chest ultrasound utilization in Italian geriatric wards is inhomogeneous, and the number of trained physicians is still limited. Geriatricians’ attitude towards chest ultrasound is generally cautious. Research and training programs are needed to spread the correct use of this technique in geriatric practice

The Geriatric Patient: The Ideal One for Chest Ultrasonography? A Review From the Chest Ultrasound in the Elderly Study Group (GRETA) of the Italian Society of Gerontology and Geriatrics (SIGG)

OBJECTIVES: To investigate the current evidence on the use of point-of-care chest ultrasonography in older patients and geriatric settings and present the current state of the art of chest ultrasound applications. DESIGN: Special article based on a literature review with narrative analyses and expert clinical knowledge. SETTING AND PARTICIPANTS: All studies performed in a geriatric setting were included. Observational and intervention studies and meta-analyses including participants aged ≥70 years were also considered, even if not specifically focused on a geriatric setting. MEASURES: Data on participant characteristics, diagnostic accuracy of chest ultrasonography, and outcomes were collected for each considered study. Data were analyzed and discussed with a particular focus on the possible applications and advantages of chest ultrasonography in geriatric medicine, underlining the possible areas of future research. RESULTS: We found only 5 studies on the diagnostic accuracy and prognostic relevance of chest ultrasonography in geriatrics. However, several studies performed in emergency departments, intensive care units, and internal medicine wards included a large number of participants ≥70 years old; they suggest that chest ultrasonography may represent a valid aid to the diagnostics of acute dyspnea, pneumonia, acute heart failure, pneumothorax, and pleural diseases, with an accuracy in some cases superior to standard x-rays, especially when mobility limitation is present. Diaphragm ultrasonography may also represent a valid tool to guide mechanical ventilation weaning in older patients with acute respiratory failure. CONCLUSIONS AND IMPLICATIONS: Chest ultrasonography may represent a valid bedside diagnostic aid to the management of acute respiratory diseases in older patients. However, specific evidence is lacking for geriatric patients. Future research will need to focus on defining the reference standards and the diagnostic accuracy for older patients with frailty and multimorbidity, cost-efficacy and cost-effectiveness of the technique, its impact for clinical outcomes, and role for follow-up in the post-acute care

Relationship between bone cross-sectional area and indices of peripheral artery disease

Most studies on the relationship between bone mineral density and atherosclerosis have used dual-energy X-ray absorptiometry, but this method is relatively insensitive to bone geometry. The aim of this study was to investigate the relationship between bone area and indices of carotid and peripheral atherosclerosis. We studied 841 persons aged 65 years or older (women = 444, mean age 73.8 years; men = 397, mean age = 75.3 years) enrolled in the InCHIANTI study and free from active malignancies, chronic use of bisphosphonates or steroids, and estrogen replacement therapy. The tibial cortical and total cross-sectional area (CSA) were measured by peripheral quantitative computed tomography and their ratio was calculated (cortical/total cross-sectional area ratio, cCSA/tCSA); carotid plaques were screened by echography, and peripheral artery disease (PAD) was defined as an ankle/brachial index <0.9 or presence of intermittent claudication. No association between cCSA/tCSA and atherosclerosis was observed in men. In women, lower cCSA/tCSA was associated with both carotid plaques [odds ratio (OR) for lowest vs. best quartile = 2.09, 95 % confidence interval (CI) 1.2-3.68] and PAD (OR = 3.43, 95 % CI 1.58-8.12). After correction for potential confounders (age since menopause, body mass index, Parathyroid hormone, vitamin D, leptin, DHEA-S, testosterone, physical activity, chronic obstructive pulmonary disease, and reduced renal function), the association was not confirmed. According to partial logistic regression, the carotid plaque-cCSA/tCSA association, but not the PAD-cCSA/tCSA association, was mostly dependent on years since menopause. In women the association between osteoporosis and carotid plaques likely reflects hormonal deprivation, whereas that between osteoporosis and PAD seems multifactorial in origin. © 2013 Springer Science+Business Media New York

Delirium in COVID-19: epidemiology and clinical correlations in a large group of patients admitted to an academic hospital

Background: Delirium incidence and clinical correlates in coronavirus disease-19 (COVID-19) pneumonia are still poorly investigated. Aim: To describe the epidemiology of delirium in patients hospitalized for suspect COVID-19 pneumonia during the pandemic peak in an academic hospital of Northern Italy, identify its clinical correlations and evaluate the association with mortality. Methods: The clinical records of 852 patients admitted for suspect COVID-19 pneumonia, defined as respiratory symptoms or fever or certain history of contact with COVID-19 patients, plus chest CT imaging compatible with alveolar-interstitial pneumonia, were retrospectively analyzed. Delirium was defined after careful revision of daily clinical reports in accordance with the Confusion Assessment Method criteria. Data on age, clinical presentation, comorbidities, drugs, baseline lab tests and outcome were collected. The factors associated with delirium, and the association of delirium with mortality, were evaluated through binary logistic regression models. Results: Ninety-four patients (11%) developed delirium during stay. They were older (median age 82, interquartile range, IQR 78–89, vs 75, IQR 63–84, p < 0.001), had more neuropsychiatric comorbidities and worse respiratory exchanges at baseline. At multivariate models, delirium was independently and positively associated with age [odds ratio (OR) 1.093, 95% confidence interval (CI) 1.046–1.143, p < 0.001], use of antipsychotic drugs (OR 4.529, 95% CI 1.204–17.027, p = 0.025), serum urea and lactate-dehydrogenase at admission. Despite a higher mortality in patients with delirium (57% vs 30%), this association was not independent of age and respiratory parameters. Conclusions: Delirium represents a common complication of COVID-19 and a marker of severe disease course, especially in older patients with neuropsychiatric comorbidity
