The purpose of this work is to provide an exhaustive overview of the emerging biosensor technologies for the detection of analytes of interest for food, environment, security, and health. Over the years, biosensors have acquired increasing importance in a wide range of applications due to synergistic studies of various scientific disciplines, determining their great commercial potential and revealing how nanotechnology and biotechnology can be strictly connected. In the present scenario, biosensors have increased their detection limit and sensitivity unthinkable until a few years ago. The most widely used biosensors are optical-based devices such as surface plasmon resonance (SPR)-based biosensors and fluorescence-based biosensors. Here, we will review them by highlighting how the progress in their design and development could impact our daily life.

Iron overload-related heart failure is the principal cause of death in transfusion dependent patients, including those with Thalassemia Major. Linking cardiac siderosis measured by T2* to therapy improves outcomes. T1 mapping can also measure iron; preliminary data suggests it may have higher sensitivity for iron, particularly for early overload (the conventional cut-point for no iron by T2* is 20ms, but this is believed insensitive). We compared T1 mapping to T2* in cardiac iron overload.
In a prospectively large single centre study of 138 Thalassemia Major patients and 32 healthy controls, we compared T1 mapping to dark blood and bright blood T2* acquired at 1.5T. Linear regression analysis was used to assess the association of T2* and T1. A \"moving window\" approach was taken to understand the strength of the association at different levels of iron overload.
The relationship between T2* (here dark blood) and T1 is described by a log-log linear regression, which can be split in three different slopes: 1) T2* low, <20ms, r2 = 0.92; 2) T2* = 20-30ms, r2 = 0.48; 3) T2*>30ms, weak relationship. All subjects with T2*<20ms had low T1; among those with T2*>20ms, 38% had low T1 with most of the subjects in the T2* range 20-30ms having a low T1.
In established cardiac iron overload, T1 and T2* are concordant. However, in the 20-30ms T2* range, T1 mapping appears to detect iron. These data support previous suggestions that T1 detects missed iron in 1 out of 3 subjects with normal T2*, and that T1 mapping is complementary to T2*. The clinical significance of a low T1 with normal T2* should be further investigated.

Gender differences in predictors of intensive care units admission among COVID-19 patients: The results of the SARS-RAS study of the Italian Society of Hypertension
2020
The global rate of intensive care unit (ICU) admission during the COVID-19 pandemic varies within countries and is among the main challenges for health care systems worldwide. Conflicting results have been reported about the response to coronavirus infection and COVID-19 outcomes in men and women. Understanding predictors of intensive care unit admission might be of help for future planning and management of the disease.
We designed a cross-sectional observational multicenter nationwide survey in Italy to understand gender-related clinical predictors of ICU admission in patients with COVID-19. We analyzed information from 2378 charts of Italian patients certified for COVID-19 admitted in 26 hospitals. Three hundred ninety-five patients (16.6%) required ICU admission due to COVID19 infection, more frequently men (74%), with a higher prevalence of comorbidities (1,78±0,06 vs 1,54±0,03 p<0.05). In multivariable regression model main predictors of admission to ICU are male gender (OR 1,74 95% CI 1,36-2,22 p<0.0001) and presence of obesity (OR 2,88 95% CI 2,03-4,07 p<0.0001), chronic kidney disease (OR: 1,588; 95%, 1,036-2,434 p<0,05) and hypertension (OR: 1,314; 95% 1,039-1,662; p<0,05). In gender specific analysis, obesity, chronic kidney disease and hypertension are associated with higher rate of admission to ICU among men, whereas in women, obesity (OR: 2,564; 95% CI 1,336-4.920 p<0.0001) and heart failure (OR: 1,775 95% CI: 1,030-3,057) are associated with higher rate of ICU admission.
Our study demonstrates that gender is the primary determinant of the disease's severity among COVID-19. Obesity is the condition more often observed among those admitted to ICU within both genders.

Depression symptoms as longitudinal predictors of the psychological impact of COVID-19 pandemic in hypertensive patients
2021
COVID-19 has brought considerable changes and caused critical psychological responses, especially among frail populations. So far, researchers have explored the predictive effect of diverse factors on pandemic-related psychological distress, but none have focused on the impact of prior depression and anxiety symptomatology adopting an extended (10-year) longitudinal design. 105 patients aged over 60, affected by hypertension who participated in a previous longitudinal study were assessed through a follow-up telephone structured interview. The Hospital Anxiety and Depression Scale (HADS) and the Impact of Event Scale-Revised (IES-R) were used for assessing depression and anxiety symptoms and the psychological impact of COVID-19, respectively. Multiple linear regression analyses were conducted. At the assessment, participants did not report clinically relevant depression, anxiety, and psychological pandemic-related distress symptoms. However, significant mean differences between baseline and current follow-up evaluations for both depression and anxiety were found, reflecting a decrease in symptomatology over time (
p
< .001). Baseline depression symptoms (
β
= 1.483,
p
= .005) significantly predicted the psychological impact of COVID-19 after 10 years. Conversely, their decrease (
β
= −1.640,
p
< .001) and living with others (
β
= −7.274,
p
= .041) significantly contributed to lower psychological distress scores. Our findings provide insight into the predisposing influence of depressive symptoms on pandemic-related psychological distress ten years later. Preventive interventions and strategies considering these factors are needed to better pre-empt the severe mental consequences of the pandemic.

Impulsivity assessed ten years earlier and sociodemographic factors predict adherence to COVID-19 related behavioral restrictions in old individuals with hypertension
2022
Background
The COVID-19 pandemic has had clear and dramatic repercussions on health, the economy, and psychosocial well-being. Behavioral measures, such as wearing facemasks and maintaining distance from others, have proven crucial in fighting the contagion’s spread. This study aimed to investigate Type A personality traits and sociodemographic predictors of adherence to governmental measures in a sample of frail individuals.
Methods
A sample of 105 Italians over age 60 (Mean age = 70 years; 60.6% male) affected by hypertension who participated in a previous longitudinal study were assessed through a telephone structured interview. Sociodemographic information and Type A personality traits were retrieved from the original longitudinal study. Adherence behaviors were investigated through several questions regarding the compliance with home confinement, the use of facemasks and the observance of social distancing. Repeated measures Analyses of Variance (RMANOVA), Reliable Change Index, and binomial logistic regression analysis were performed.
Results
Only 33.3% of the participants reported adherence to all the governmental COVID-19 measures. Being a woman (OR = 4.84; 95% CI = 1.58, 14.90;
p
< 0.01), being retired (OR = 4.89; 95% CI = 1.09, 21.86;
p
< 0.05), and suffering from hypertension for a relatively short time (OR = 4.20; 95% CI = 1.22, 14.44;
p
< 0.05) positively predicted adherence to the governmental measures. Impulsivity resulted in a stable personality characteristic over the last ten years (
p
= 0.30). Having high levels of impulsivity (OR = 2.28; 95% CI = 1.13, 4.59;
p
< 0.05) negatively predicted adherence.
Conclusions
Our results demonstrate that impulsivity is a stable personality facet that can have a robust negative impact on adherence behaviors to health claims. Overall, results show the importance to tailor communication strategies that consider the role of sociodemographic indicators and impulsivity to achieve a high level of adherence.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) is an increasingly recognized clinical entity characterized by myocardial injury in the absence of a significant coronary artery obstruction. MINOCA encompasses a diverse range of pathophysiological mechanisms, including coronary plaque disruption, coronary vasospasm, coronary microvascular dysfunction, thromboembolism, and spontaneous coronary artery dissection. A systematic diagnostic approach is essential to identify the underlying etiology and guide appropriate management strategies. Advanced imaging techniques, particularly cardiac magnetic resonance, play a pivotal role in distinguishing ischemic from non-ischemic myocardial injury and refining prognosis. Despite growing awareness, standardized treatment protocols remain limited, with current management largely extrapolated from strategies used in obstructive coronary artery disease. Notably, MINOCA is significantly more prevalent in women, emphasizing the need to understand sex-related differences in its pathophysiology, presentation, and clinical outcomes. This narrative review offers a comprehensive and up-to-date overview of MINOCA, including a dedicated chapter on sex-related considerations. It integrates recent advancements and highlights the importance of personalized management strategies.

Background
This study explored both the evolution of the information needs and the perceived relevance of different health information sources in patients with essential hypertension. It also investigated the relationships between information needs and the perceived relevance of information sources with socio-demographic and clinical variables.
Methods
Two hundred and two patients with essential arterial hypertension were enrolled in the study and evaluated at baseline and during three follow-ups at 6, 12 and 24 months after baseline. Patients had a mean age of 54.3 years [range 21–78; SD = 10.4], and 43% were women. Repeated measures ANOVA, Bonferroni post hoc tests, and Cochran’s Q Test were performed to test differences in variables of interest over time.
Results
It was observed a significant reduction in all the domains of information needs related to disease management except for pharmacological treatment and risks and complications. At baseline, patients reported receiving health information primarily from specialists, general practitioners, relatives, and television, but the use of these sources decreased over time, even if the decrease was significant only for relatives. Multiple patterns of relationships were found between information needs and the perceived relevance of sources of information and socio
-
demographics and clinical variables, both at baseline and over time.
Conclusions
The findings showed a general decrease in both the desire for information and the perceived relevance of different information sources. Hypertensive patients appeared to show little interest in health communication topics as their disease progressed. Understanding patients’ information needs and the perceived relevance of different information sources is the first step in implementing tailored communication strategies that can promote patients’ self-management skills and optimal clinical outcomes.

Hypertensive emergencies and urgencies: a preliminary report of the ongoing Italian multicentric study ERIDANO
2023
Hypertensive urgencies (HU) and hypertensive emergencies (HE) are challenges for the Emergency Department (ED). A prospective multicentre study is ongoing to characterize patients with acute hypertensive disorders, prevalence of subclinical hypertension-mediated organ damage (HMOD), short- and long-term prognosis; this is a preliminary report. Patients admitted to the ED with symptomatic blood pressure (BP) ≥180/110 mmHg were enrolled. They were managed by ED personnel according to their clinical presentations. Subsequently they underwent clinical evaluation and subclinical HMOD assessment at a Hypertension Centre within 72 h from enrolment. 122 patients were included in this report. Mean age was 60.7±13.9 years, 52.5% were females. 18 (14.8%) patients were diagnosed with HE, 108 (88.5%) with HU. There were no differences in gender, BMI, and cardiovascular comorbidities between groups. At ED discharge, 66.7% and 93.6% (
p
= 0.003) of HE and HU patients, respectively, had BP < 180/110 mmHg. After 72 h, 34.4% of patients resulted normotensive; 35.2%, 22.1%, and 8.2% had hypertension grade 1, 2, and 3, respectively. Patients with uncontrolled BP at office evaluation had higher vascular HMOD (49.1 vs. 25.9%,
p
= 0.045). Cardiac (60 vs. 34%,
p
= 0.049), renal (27.8 vs. 9.6%,
p
= 0.010) and cerebral (100 vs. 21%,
p
< 0.001) HMOD was more frequent in HE compared to HU group. HE showed greater cardiac, renal, and cerebral subclinical HMOD, compared to HU. 72-hours BP control is not associated with different HMOD, except for vascular HMOD; therefore, proper comprehensive examination after discharge from the ED could provide added value in cardiovascular risk stratification of such patients.
One third of patients with acute blood pressure rise evaluated to the ED resulted normotensive at office evaluation (<72 hours after discharge). Patients with hypertensive emergency showed greater cardiac, renal, and cerebral subclinical HMOD, compared to the patients with hypertensive urgency. BP: blood pressure; HMOD: hypertension-mediated organ damage; y.o.: years old; mo.: months.

A 59-year-old woman was admitted to our emergency department for asthenia and swollen ankles. 1 week earlier she began to feel tired while walking. On clinical examination, we found peripheral oedema but no other signs suggestive of heart failure. Her blood pressure was 150/70 mm Hg. An electrocardiogram showed junctional bradycardia (35 beats per min): P waves were absent and the QRS complexes were regular and narrow. In her medical history, it was noted that she had recently been treated with ibuprofen and colchicine for acute idiopathic pericarditis: the patient had chest pain and paroxysmal atrial flutter.

Uric acid (UA) is the final product of the catabolism of endogenous and exogenous purine nucleotides. While its association with articular gout and kidney disease has been known for a long time, new data have demonstrated that UA is also related to cardiovascular (CV) diseases. UA has been identified as a significant determinant of many different outcomes, such as all-cause and CV mortality, and also of CV events (mainly Acute Coronary Syndromes (ACS) and even strokes). Furthermore, UA has been related to the development of Heart Failure, and to a higher mortality in decompensated patients, as well as to the onset of atrial fibrillation. After a brief introduction on the general role of UA in CV disorders, this review will be focused on UA’s relationship with CV outcomes, as well as on the specific features of patients with ACS and Chronic Coronary Syndrome. Finally, two issues which remain open will be discussed: the first is about the identification of a CV UA cut-off value, while the second concerns the possibility that the pharmacological reduction of UA is able to lower the incidence of CV events.
