Carbapenemase-producing Klebsiella pneumoniae in elderly frail patients admitted to medical wards

Carbapenemase-producing Klebsiella pneumoniae (CPKP) is rapidly emerging as a leading nosocomial infection in many countries, especially in Italy where it is considered endemic. In this paper we briefly summarize the main characteristics of this outbreak, focusing on its recent spread to elderly frail patients admitted to internal medicine and geriatric wards. Severity of disease, clinical complexity and a large number of comorbidities seem to be major risk factors in clinical practice, although scientific evidence is still lacking, since until now studies have been carried out mainly in intensive care settings. We also discuss the possible role of gut microbiota in CPKP colonization onset and the possible role of pre-probiotics in promoting eradication

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

Is adrenaline misused in anaphylaxis treatment? Experience of a large, urban Emergency Department: review of 589 cases.

Objective. Acute allergic reactions are important causes of Emergency Department (ED) admissions. Although the current recommendations for treatment of patients with anaphylaxis are focused on the central role of adrenaline, evidence in support of this therapy is still scarce. We planned a retrospective analysis of all allergic and anaphylactic reactions managed in the ED, to assess adherence to current guidelines and clinical outcomes. Methods. The study population consisted of all consecutive adult patients admitted to the ED with acute allergic reactions during the year 2013. Overall, the final study population consisted of 589 patients, i.e., 329 women and 260 men (55.9% vs. 44.1%, mean age 43±18 years, range 16-96 years). Results. Fifty-six patients were diagnosed with anaphylaxis (9.5%), 75 with angioedema (12.7%), 363 with urticaria (61.7%), and 95 with urticaria-angioedema (16.1%). The triggers included drugs (21.9%), foods (15.0%), hymenoptera stings (9.9%), and chemicals (4.4%), whereas a specific cause could not be recognized in nearly half of the cases. Only 5 (8.9%) of 56 patients diagnosed with anaphylaxis received adrenaline and no death or Intensive Care Unit (ICU) admission occurred within one month from the acute allergic episode. Conclusion. The results of our study suggest that anaphylaxis is widely undertreated with adrenaline in our local ED compared to guidelines and recommendations. Nevertheless, a favorable outcome was recorded for all patients included in the study, even when managed with second- and third-line treatments, as attested by the lack of deaths at 1 month and the very limited number of hospitalizations (3/589; 0.5%), related to comorbidities rather than to treatment failure. The strength of recommendations contained in current guidelines should hence be reconsidered

Defining SARS-CoV-2 breakthrough infection needing hospitalization in mass vaccination era: from disease-centered to patient-centered care

After the implementation of mass vaccination campaigns, breakthrough infections by SARS-CoV-2 are being increasingly observed worldwide, due to high pervasiveness of viral spread, emergence of novel variants, progressive ease of restrictive measures and waning protection against infection. Although breakthrough infections have generally lower clinical severity than COVID-19 in unvaccinated subjects, a consistent number of patients may still require hospitalization. These patients are generally old, frail and with a high number of comorbidities. Despite COVID-19-related symptoms are generally milder, they may still exhibit complicated clinical course for their intrinsic clinical complexity. The organization of hospital care should thus consider the changing epidemiology of patients admitted with SARS-CoV-2 infection in the post-vaccine era, to improve the quality and appropriateness of care

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

Fad diets and their effect on urinary stone formation

Abstract: The influence of unhealthy dietary habits on urinary stone formation has been widely recognized in literature. Dietary advice is indeed the cornerstone prescription for prevention of nephrolithiasis as well. However, only a small amount of medical literature has addressed the influence of popular or fad diets, often self-prescribed for the management of obesity and overweight or for cultural beliefs, on the risk of kidney stones. Thereby in this paper we analyze the current knowledge on the effects of some popular diets on overall lithogenic risk. High-protein diets, like Dukan diet, raise some concerns, since animal proteins are able to increase urinary calcium and to decrease urinary citrate excretion, thus leading to a high overall lithogenic risk. Low-carbohydrate diets, like Atkins diet or zone diet, may have a protective role against kidney stone formation, but there are also evidences stating that this dietary approach may rise calciuria and decrease citraturia, since it is generally associated to a relatively high intake of animal proteins. Vegan diet can be harmful for urinary stone disease, especially for the risk of hyperuricemia and micronutrient deficiencies, even if only few studies have addressed this specific matter. On the other side, the benefits of a lacto-ovo-vegetarian diet on kidney stone prevention have been largely emphasized, provided that the intake of calcium and oxalate is balanced. Traditional Mediterranean diet should exert a protective effect on nephrolithiasis as well, even if specific studies have not been carried out yet. High phytate and antioxidant content of this diet have however demonstrated to be beneficial in preventing the formation of new or recurrent calculi. Anyway, at the current state of knowledge, the most effective dietary approach to prevent kidney stone disease is a mild animal protein restriction, a balanced intake of carbohydrates and fats and a high intake of fruit and vegetables. Other fundamental aspects, which are often neglected in fad diets, are a normal intake of milk and dairy products and salt restriction. All these nutritional aspects should be greatly taken into account when patients who are willing to undergo fad or commercial diets ask for dietary advice

Effects of the COVID-19 Epidemic on Hospital Admissions for Non-Communicable Diseases in a Large Italian University-Hospital: A Descriptive Case-Series Study

Background: Concern is growing about the negative consequences that response measures to the COVID-19 epidemic may have on the management of other medical conditions. Methods: A retrospective descriptive case-series study conducted at a large University-hospital in northern Italy, an area severely hit by the epidemic. Results: Between 23 February and 14 May 2020, 4160 (52%) COVID-19 and 3778 (48%) non-COVID-19 patients were hospitalized. COVID-19 admissions peaked in the second half of March, a period characterized by an extremely high mortality rate (27.4%). The number of admissions in 2020 was similar to 2019, but COVID-19 patients gradually occupied all available beds. Comparison between COVID-19 and non-COVID-19 admissions in 2020 revealed significant differences concerning all age classes and gender. Specifically, COVID-19 patients were older, predominantly male, and exhibited more comorbidities. Overall, admissions for non-communicable diseases (NCDs) in 2020 vs. 2019 dropped by approximately one third. Statistically significant reductions were observed for acute myocardial infarction (−78, −33.9%), cerebrovascular disease (−235, −41.5%), and cancer (−368, −31.9%). While the first two appeared equally distributed between COVID-19 and non-COVID-19 patients, chronic NCDs were statistically significantly more frequent in the former, except cancer, which was less frequent in COVID-19 patients. Conclusions: Prevention of collateral damage to patients with other diseases should be an integral part of epidemic response plans. Prospective cohort studies are needed to understand the long-term impact

Accounting for frailty and multimorbidity when interpreting high-sensitivity troponin I tests in oldest old

Background Older patients evaluated in Emergency Departments (ED) for suspect Myocardial Infarction (MI) frequently exhibit unspecific elevations of serum high-sensitivity troponin I (hs-TnI), making interpretation particularly challenging for emergency physicians. The aim of this longitudinal study was to identify the interaction of multimorbidity and frailty with hs-TnI levels in older patients seeking emergency care. Methods A group of patients aged≥75 with suspected MI was enrolled in our acute geriatric ward immediately after ED visit. Multimorbidity and frailty were measured with Cumulative Illness Rating Scale (CIRS) and Clinical Frailty Scale (CFS), respectively. The association of hs-TnI with MI (main endpoint) was assessed by calculation of the Area Under the Receiver-Operating Characteristic Curve (AUROC), deriving population-specific cut-offs with Youden test. The factors associated with hs-TnI categories, including MI, CFS and CIRS, were determined with stepwise multinomial logistic regression. The association of hs-TnI with 3-month mortality (secondary endpoint) was also investigated with stepwise logistic regression. Results Among 268 participants (147 F, median age 85, IQR 80–89), hs-TnI elevation was found in 191 cases (71%, median 23 ng/L, IQR 11–65), but MI was present in only 12 cases (4.5%). hs-TnI was significantly associated with MI (AUROC 0.751, 95% CI 0.580–0.922, p = 0.003), with an optimal cut-off of 141 ng/L. hs-TnI levels ≥141 ng/L were significantly associated with CFS (OR 1.58, 95% CI 1.15–2.18, p = 0.005), while levels <141 ng/L were associated with the cardiac subscore of CIRS (OR 1.36, 95% CI 1.07–1.71, p = 0.011). CFS, but not hs-TnI levels, predicted 3-month mortality. Conclusions In geriatric patients with suspected MI, frailty and cardiovascular multimorbidity should be carefully considered when interpreting emergency hs-TnI testing
