Respiratory Viruses in Patients With Hematological Malignancy in Boreal Autumn/Winter 2023-2024: EPICOVIDEHA-EPIFLUEHA Report.

Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season.

Nirmatrelvir/ritonavir in COVID-19 patients with haematological malignancies: a report from the EPICOVIDEHA registry.

Background: Nirmatrelvir/ritonavir treatment decreases the hospitalisation rate in immunocompetent patients with COVID-19, but data on efficacy in patients with haematological malignancy are scarce. Here, we describe the outcome of nirmatrelvir/ritonavir treatment in a large cohort of the latter patients.

Methods: This is a retrospective cohort study from the multicentre EPICOVIDEHA registry (NCT04733729) on patients with haematological malignancy, who were diagnosed with COVID-19 between January and September 2022.

Atypical Presentation of Acetylcholinesterase Inhibitor-Induced Diarrhea in Older Adults with Cognitive Decline: An Aspect not to be Underestimated.

The rivastigmine patch is the only existing transdermal delivery system used for the treatment of Alzheimer disease. Among the most common adverse events derived from its use are gastrointestinal events, particularly diarrhea. We report a clinical case of an 81-year-old patient admitted to our hospital under long-standing treatment with rivastigmine transdermal patch who presented with atypical watery diarrhea.

Independent association of plasma leptin levels and left ventricular isovolumic relaxation in uncomplicated hypertension.

Background: On the basis of evidence of plasma leptin (LE) effects on cardiovascular system, we assessed possible association of LE and Doppler-derived left ventricular (LV) diastolic function in arterial hypertension.

Methods: Doppler echocardiography, blood sample for fasting plasma LE levels, and euglycemic hyperinsulinemic glucose clamp were performed on 15 healthy insulin-sensitive men and 40 newly diagnosed hypertensive men, who were divided into two groups according to insulin sensitivity degree: 15 insulin sensitive (IS) and 25 insulin resistant (IR) individuals (whole body glucose disposal >33.3 and <33.

Inverse association between free insulin-like growth factor-1 and isovolumic relaxation in arterial systemic hypertension.

Several trials have suggested that insulin-like growth factor-1 (IGF-1) may have a pathophysiological role in the development of arterial essential hypertension. To verify the possible association of IGF-1 with left ventricular morphological and functional echocardiographic parameters in hypertension, we studied 40 male patients with newly diagnosed hypertension and 15 normotensive control subjects. Doppler echocardiography was performed and circulating free IGF-1 levels were determined in all subjects.

Modulation of drug release from hydrogels by using cyclodextrins: the case of nicardipine/beta-cyclodextrin system in crosslinked polyethylenglycol.

A simple approach is presented to modulate drug delivery from swellable systems by using complexants. The effect of complexants has been interpreted by means of simple mass balances on diffusing species and the involved relevant parameters have been individuated. The application of this strategy to the release of nicardipine (NIC) from swellable systems by using beta-cyclodextrin (CD) as complexant has evidenced the potential of the approach to tailor drug release.

Elevated plasma fatty acid concentrations stimulate the cardiac autonomic nervous system in healthy subjects.

Background: Fatty acids have been shown to stimulate the sympathetic nervous system in rats. Power spectral analysis of heart rate variability (HRV) is a safe and useful tool with which to evaluate cardiac autonomic nervous system (ANS) activity. Whether changes in plasma fatty acid concentrations affect the sympathetic nervous system or HRV in humans is unknown.

Effects of insulin on the cardiac autonomic nervous system in insulin-resistant states.

The effects of insulin infusion on cardiac autonomic nervous system (ANS) activity were investigated in healthy subjects (n=15) and in patients with various types of insulin-resistance, such as obese subjects (n=20) and those with hypertension (n=15) or type II (non-insulin-dependent) diabetes (n=22). Healthy subjects and patients underwent euglycaemic hyperinsulinaemic glucose clamp, and cardiac ANS and haemodynamic changes were investigated by continuous recording of heart rate variability by the Holter technique and by venous occlusion plethysmography respectively. At baseline, healthy subjects had the highest values for total spectral power and the low-frequency (LF) component, and the lowest value for the high-frequency (HF) component.

Chronic vitamin E administration improves brachial reactivity and increases intracellular magnesium concentration in type II diabetic patients.

Vascular disease accounts for the majority of the clinical complications in diabetes mellitus. As an exaggerated oxidative stress degree has been postulated as the link between diabetes mellitus and endothelial function, a possible positive effect of plasma vitamin E (Vit.E) administration on brachial reactivity could be postulated.

Lack of association between changes in plasma leptin concentration and in food intake during the menstrual cycle.

Background: Changes in plasma leptin concentration and food intake occur during the menstrual cycle; because leptin regulates food intake, one could hypothesize that changes in plasma leptin concentration and in food intake are associated throughout the menstrual cycle. However, no data have ever been provided to support such a relationship. The aim of our study was to investigate, during the different phases of the menstrual cycle, (a) the changes in plasma leptin concentration and, if such changes were demonstrated, (b) the potential relationship between the changes in plasma leptin concentration and food intake.

Prognostic importance of insulin-mediated glucose uptake in aged patients with congestive heart failure secondary to mitral and/or aortic valve disease.

Previous studies have demonstrated that insulin resistance is a common feature of congestive heart failure (CHF), but the clinical significance of such insulin resistance is still debated. We tested the hypothesis that insulin-mediated glucose uptake (IMGU) is a prognostic factor in CHF in aged patients. For this purpose 174 aged patients with CHF participated in a cross-sectional and a longitudinal study of 24 months' duration.

Effect of metformin on food intake in obese subjects.

Background: It has been hypothesized that metformin inhibits food intake, but in humans such effect needs to be demonstrated. Our study aims at investigating the effect of metformin administration on food intake in obese, non-diabetic, normotensive patients.

Methods: Thirty patients underwent a double-blind, randomized study.

Losartan mediated improvement in insulin action is mainly due to an increase in non-oxidative glucose metabolism and blood flow in insulin-resistant hypertensive patients.

We investigated the possible role of losartan on insulin-mediated glucose uptake, substrate oxidation and blood flow in insulin-resistant hypertensive patients. Sixteen newly diagnosed patients with mild-to-moderate hypertension were studied. The study design was a single-blind, randomised, placebo-controlled trial.

Effects of prolonged autovehicle driving on male reproduction function: a study among taxi drivers.

This study had the purpose of exploring the possible association between the work exposures of professional drivers and their reproductive health, by studying a group of 201 taxi drivers in the city of Rome. Data on work and reproductive history were collected by interviews. Biological markers examined in 72 subjects included salivary testosterone levels, sperm quality (i.

The therapy of aged diabetic hypertensives.

The great prevalence and incidence of non-insulin dependent diabetes mellitus (NIDDM) and hypertension in the elderly represent several therapeutic problems. Due to aged-related changes in glucose handling and cardiovascular functions which occur with advancing age, it is necessary to treat aged diabetic hypertensive patients with drugs lowering arterial blood pressure but without side effects on glucose metabolism. Non-pharmacological and pharmacological protocols can be taken into account.

Clinical effects of oral theophylline in elderly patients with sick sinus syndrome.

Theophylline increases the heart rate in patients with normal sinus rhythm and in patients with sick sinus syndrome. This effect is probably connected to the blockade of adenosine receptors by theophylline. This study evaluated the efficacy of theophylline in 34 elderly patients with symptomatic sinus bradycardia (age 68 +/- 11 years).

Regression of left ventricular hypertrophy in hypertensive elderly patients with carvedilol.

In hypertensive patients, the development of left ventricular hypertrophy seems to increase the risk of cardiovascular death although some antihypertensive agents have been associated with regression in left ventricular hypertrophy. A few studies have evaluated the carvedilol, a new drug having a balanced pharmacology of vasodilatation and beta-receptor blockade, particularly in elderly hypertensive patients. To test its effects on left ventricular hypertrophy, patients with essential hypertension and left ventricular hypertrophy were studied before and at the end of 6 months of therapy with 25 mg of carvedilol daily.

Metabolic benefits deriving from chronic vitamin C supplementation in aged non-insulin dependent diabetics.

Objective: Our study investigated the metabolic benefits deriving from chronic pharmacological vitamin C administration in aged non-insulin dependent (Type II) diabetic patients.

Methods: Forty type II diabetic patients (age: 72 +/- 0.5 years) underwent placebo and vitamin C (0.

Lisinopril administration improves insulin action in aged patients with hypertension.

Thirty elderly, mildly hypertensive patients were enrolled for a single-blind, randomised cross-over placebo controlled trial in which placebo and lisinopril (20 mg/day before breakfast) were given for 4 and 8 weeks, respectively. A wash-out period of 3 weeks between placebo and lisinopril was observed. In each patient a euglycaemic glucose clamp with simultaneous indirect calorimetry allowed us to determine whole body glucose disposal and substrate oxidation.

Left ventricular hypertrophy is associated with a stronger impairment of non-oxidative glucose metabolism in hypertensive patients.

Hypertensive patients with left ventricular hypertrophy (LVH) have a higher degree of hyperinsulinaemia than hypertensive patients without LVH. Obese patients with LVH have also been demonstrated to have a very low glucose disappearance rate after an intravenous glucose bolus. No studies have investigated the difference in insulin action and substrate oxidation in hypertensive patients with and without LVH.

Low-dose Iloprost infusion improves insulin action and non-oxidative glucose metabolism in hypertensive patients.

Fourteen hypertensive (174.3/98.3 mmHg) non-diabetic patients were given a euglyceamic glucose clamp along with infusion of 0.

Pharmacological doses of vitamin E and insulin action in elderly subjects.
