RESUMO
Ischemia with non-obstructive coronary artery (INOCA) is a common cause of hospital admissions, leading to negative outcomes and reduced quality of life. Central to its pathophysiology is endothelial dysfunction, which contributes to myocardial ischemia despite the absence of significant coronary artery blockage. Addressing endothelial dysfunction is essential in managing INOCA to alleviate symptoms and prevent cardiovascular events. Recent studies have identified diabetes mellitus (DM) as a significant factor exacerbating INOCA complications by promoting endothelial impairment and coronary microvascular dysfunction. MicroRNAs (miRNAs) have emerged as potential biomarkers and therapeutic targets in various biological processes, including endothelial dysfunction and cardiovascular diseases. However, research on miRNA biomarkers in INOCA patients is sparse. In this study, we examined a panel of circulating miRNAs involved in the regulation of endothelial function in INOCA patients with and without DM. We analyzed miRNA expression using RT-qPCR in a cohort of consecutive INOCA patients undergoing percutaneous coronary intervention. We detected a significant dysregulation of miR-363-5p and miR-92a-3p in INOCA patients with DM compared to those without DM, indicating their role as biomarkers for predicting and monitoring endothelial dysfunction in INOCA patients with DM.

As respiratory syncytial virus (RSV) vaccine distribution gains traction in Europe and Italy, healthcare workers (HCWs) can strategize about vaccine promotion to increase uptake among patients at risk of RSV consequences, such cardiac patients. This cross-sectional survey investigated the knowledge about and attitude towards RSV and RSV vaccines, and the intention to recommend vaccination within a cardiological hospital in Italy. To explore factors associated with the outcomes of interest, multivariate logistic regression analyses were conducted. Of 197 invited HCWs, 78.2% returned the survey. The knowledge about market authorisation for new RSV vaccines for older adults (present in 46.9% of respondents) was significantly associated with the HCWs' age, education, and previous update on vaccinations. HCWs with a higher educational level and those with a positive attitude towards RSV vaccines safety reported a higher attitude towards the importance of vaccinating people at risk. The willingness of recommending RSV vaccination to patients (70.5% of respondents) was more likely in HCWs who were knowledgeable about market authorisation for RSV vaccines and in physicians. This tempestive research sheds light on current factors influencing the strategies of cardiac HCWs regarding RSV vaccination. The results suggest the need for training events on the protective role of RSV vaccination in cardiac patients.
RESUMO
Background and Objectives: Cardiac patients are particularly at risk of herpes zoster (HZ), which is associated with a higher risk of major cardiovascular events. This research aimed to analyze the knowledge, attitudes and practices towards recombinant zoster vaccine (RZV) among cardiac healthcare professionals (HPs). Materials and Methods: A cross-sectional survey was conducted in a cardiological hospital in Italy. Multivariate regression models were built to identify factors associated with the outcomes of interest. Results: The response rate was 78.2% (154/197). Overall, age > 50 years and immunosuppression were recognized as risk factors for HZ by 38.3% and 75.3% of respondents, respectively. Regarding RZV, 29.1% of the HPs correctly responded about its schedule and 57.6% about the possibility of administration in immunocompromised individuals. This knowledge was significantly higher in HPs with a higher educational level (odds ratio (OR) = 4.42; 95%CI 1.70-11.47), in those who knew that HZ could cause postherpetic neuralgia (OR = 2.56; 95%CI 1.05-6.25) or major cardiovascular events (OR = 4.23; 95%CI 1.50-11.91), in those who had participated in professional updates on vaccinations (OR = 3.86; 95%CI 1.51-9.87) and in those who stated the need for further information about the RZV (OR = 6.43; 95%CI 1.42-29.98). Younger HPs (coefficient (ß) = -0.02; 95%CI -0.04--0.01), those with a positive attitude toward RZV safety (ß = 2.92; 95%CI 2.49-3.36) and those who had previously cared for patients with HZ (ß = 0.45; 95%CI 0.03-0.88) reported a more positive attitude toward RZV effectiveness. The practice of recommending vaccination was more prevalent in younger HPs (OR = 0.94; 95%CI 0.89-0.99), in those who had a master's degree or higher education (OR = 7.21; 95%CI 1.44-36.08), in those with more positive attitudes toward RZV effectiveness (OR = 7.17; 95%CI 1.71-30.03) and in HPs who had already recommended the vaccine to patients in the past (OR = 4.03; 95%CI 1.08-14.96). Conclusions: Despite being a single-center study, our research brings attention to factors that currently impact cardiac HPs' approaches to RZV. The findings indicate potential measures to enhance HPs' awareness and practices, ultimately aiming to improve vaccination adherence and reduce the burden associated with HZ.

SGLT2 (sodium-glucose cotransporter 2) enables glucose and sodium reabsorption in the kidney. SGLT2-inhibitors (also known as gliflozins, which include canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin) act by increasing glycosuria, thereby reducing glycemia. These drugs are critical to reach and keep glycemic control, a crucial feature, especially in patients with comorbidities, like frail individuals. Several studies evaluated the effects of SGLT2-inhibitors in different settings beyond diabetes, revealing that they are actually pleiotropic drugs. We recently evidenced the favorable effects of SGLT2-inhibition on physical and cognitive impairment in frail older adults with diabetes and hypertension. In the present overview, we summarize the latest clinical and preclinical studies exploring the main effects of SGLT2-inhibitors on kidney and heart, emphasizing their potential beneficial actions in frailty.

BACKGROUND: Few data are available on the prognosis of older patients who received corticosteroids for COVID-19. We aimed to compare the in-hospital mortality of geriatric patients hospitalized for COVID-19 who received corticosteroids or not. METHODS: We conducted a multicentric retrospective cohort study in 15 acute COVID-19 geriatric wards in the Paris area from March to April 2020 and November 2020 to May 2021. We included all consecutive patients aged 70 years and older who were hospitalized with confirmed COVID-19 in these wards. Propensity score and multivariate analyses were used. RESULTS: Of the 1 579 patients included (535 received corticosteroids), the median age was 86 (interquartile range 81-91) years, 56% of patients were female, the median Charlson Comorbidity Index (CCI) was 2.6 (interquartile range 1-4), and 64% of patients were frail (Clinical Frailty Score 5-9). The propensity score analysis paired 984 patients (492 with and without corticosteroids). The in-hospital mortality was 32.3% in the matched cohort. On multivariate analysis, the probability of in-hospital mortality was increased with corticosteroid use (odds ratio [OR] = 2.61 [95% confidence interval (CI) 1.63-4.20]). Other factors associated with in-hospital mortality were age (OR = 1.04 [1.01-1.07], CCI (OR = 1.18 [1.07-1.29], activities of daily living (OR = 0.85 [0.75-0.95], oxygen saturation < 90% on room air (OR = 2.15 [1.45-3.17], C-reactive protein level (OR = 2.06 [1.69-2.51], and lowest lymphocyte count (OR = 0.49 [0.38-0.63]). Among the 535 patients who received corticosteroids, 68.3% had at least one corticosteroid side effect, including delirium (32.9%), secondary infections (32.7%), and decompensated diabetes (14.4%). CONCLUSIONS: In this multicentric matched-cohort study of geriatric patients hospitalized for COVID-19, the use of corticosteroids was significantly associated with in-hospital mortality.

BACKGROUND: It is not known if widespread vaccination can prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in subpopulations at high risk, like older adults in nursing homes (NH). OBJECTIVE: The objective of the study was to know if coronavirus disease 2019 (COVID-19) outbreaks can occur in NH with high vaccination coverage among its residents. METHODS: We identified, using national professional networks, NH that suffered COVID-19 outbreaks despite having completed a vaccination campaign, and asked them to send data, using predefined collecting forms, on the number of residents exposed, their vaccination status and the number, characteristics, and evolution of patients infected. The main outcome was to identify outbreaks occurring in NH with high vaccine coverage. Secondary outcomes were residents' risk of being infected, developing severe disease, or dying from COVID-19 during the outbreak. SARS-CoV-2 infection was defined by a positive reverse transcriptase-polymerase chain reaction. All residents were serially tested whenever cases appeared in a facility. Unadjusted secondary attack rates, relative risks, and vaccine effectiveness during the outbreak were estimated. RESULTS: We identified 31 NH suffering an outbreak during March-April 2021, of which 27 sent data, cumulating 1,768 residents (mean age 88.4, 73.4% women, 78.2% fully vaccinated). BNT162b2 was the vaccine employed in all NH. There were 365 cases of SARS-CoV-2 infection. Median secondary attack rates were 20.0% (IQR 4.4%-50.0%) among unvaccinated residents and 16.7% (IQR 9.5%-29.2%) among fully vaccinated ones. Severe cases developed in 42 of 80 (52.5%) unvaccinated patients, compared with 56 of 248 (22.6%) fully vaccinated ones (relative risks [RR] 4.17, 95% CI: 2.43-7.17). Twenty of the unvaccinated patients (25.0%) and 16 of fully vaccinated ones (6.5%) died from COVID-19 (RR 5.11, 95% CI: 2.49-10.5). Estimated vaccine effectiveness during the outbreak was 34.5% (95% CI: 18.5-47.3) for preventing SARS-CoV-2 infection, 71.8% (58.8-80.7) for preventing severe disease, and 83.1% (67.8-91.1) for preventing death. CONCLUSIONS: Outbreaks of COVID-19, including severe cases and deaths, can still occur in NH despite full vaccination of a majority of residents. Vaccine remains highly effective, however, for preventing severe disease and death. Prevention and control measures for SARS-CoV-2 should be maintained in NH at periods of high incidence in the community.

BACKGROUND: We wanted to better understand the frequency and temporal distribution of symptoms of COVID-19 in very old patients, which are currently not well defined. METHODS: In an observational, descriptive study, we followed all patients being at three geriatric convalescence and rehabilitation units when a COVID-19 outbreak emerged in those units in March 2020. For those who developed the disease, we recorded any new symptom occurring at diagnosis, in the previous 14 and the following 21 days. A group of SARS-Cov-2-negative patients served as controls. RESULTS: Sixty-nine of the 176 inpatients (mean age: 86 years) were infected by SARS-Cov-2 during the outbreak. At the moment of diagnosis, a majority of patients had fever (71.0%), malaise-asthenia (24.6%), or respiratory symptoms (66.7%). However, 48 patients (69.6% of all SARS-Cov-2 positive patients) also presented, usually several days before, other symptoms: (a) gastrointestinal symptoms (39.1% of all patients, median onset eight days before diagnosis, IQR -9 to +3 days); (b) neurological symptoms (30.4% of all patients, median onset five days before diagnosis, IQR -11 to -3 days), notably delirium (24.6%); and (c) other symptoms, like falls and unexplained decompensation of chronic conditions (29.0% of all patients, median onset four days before diagnosis, IQR -10 to 0). None of those symptoms were observed in similar proportion in 25 control SARS-CoV-2-negative patients, hospitalized during the same period. CONCLUSIONS: Diarrhea, nausea-vomiting, delirium, falls, and unexplained decompensation of chronic conditions were the first symptoms of COVID-19 in a majority of older patients in this cohort, preceding typical symptoms by several days. Recognizing those early symptoms could hasten the diagnosis of COVID-19 in this population.

Background: Management of penetrating abdominal war injuries centers upon triage, echeloned care, and damage control. A civilian hospital based in a war zone can rarely rely upon these principles because it normally has limited resources and lacks rapid medical evacuation. We designed this study to describe organ injury patterns and factors related to mortality in patients with penetrating abdominal war injuries in a civilian hospital in an active war zone in Afghanistan, examine how these findings differ from those in a typical military setting, and evaluate how they might improve patients' care. Methods: We reviewed the records of all patients admitted at the Lashkargah "Emergency" hospital with penetrating abdominal injuries treated from January 2006 to December 2016. Demographic and clinical data were recorded; univariate and multivariate analyses were used to identify variables significantly associated with death. Results: We treated 953 patients for penetrating abdominal injury. The population was mainly civilian (12.1% women and 21% under 14). Mean age was 23 years, and patients with blast injuries were younger than in the other groups. The mechanism of injury was bullet injury in 589 patients, shell injury in 246, stab wound in 97, and mine injury in 21. The most frequent abdominal lesion was small bowel injury (46.3%). Small and large bowel injuries were the most frequent in the blast groups, stomach injury in stab wounds. Overall mortality was 12.8%. Variables significantly associated with death were age > 34 years, mine and bullet injury, length of stay, time since injury > 5 h, injury severity score > 17, and associated injuries. Conclusions: Epidemiology and patterns of injury in a civilian hospital differ from those reported in a typical military setting. Our population is mainly civilian with a significant number of women and patients under 14 years. BI are more frequent than blast injuries, and gastrointestinal injuries are more common than injuries to solid organs. In this austere setting, surgeons need to acquire a wide range of skills from multiple surgical specialties. These findings might guide trauma and general surgeons treating penetrating abdominal war wounds to achieve better care and outcome.
