RESUMO
IMPORTANCE: Real-time quantitative PCR (RT-qPCR) on nasopharyngeal swabs (NPS) has been used as the standard method for detecting and monitoring SARS-CoV-2 infection during the pandemic. However, NPS collection often causes discomfort and poses a higher risk of transmission to health care workers (HCW). Furthermore, RT-qPCR only provides relative quantification and does not allow distinguishing those samples with residual, no longer active infection, whereas droplet digital PCR (ddPCR) allows for precise quantification of viral load, offering greater sensitivity and reproducibility. This study highlights the effectiveness of using self-collected saliva as a convenient and reliable sampling method. By utilizing ddPCR to measure the SARS-CoV-2 viral load in saliva samples, individuals with low or undetectable viral loads can be quickly identified. This approach is particularly advantageous for surveillance programs targeting HCW, as it enables the early identification and release of uninfected personnel, minimizing lost workdays. Additionally, analyzing viral load in saliva samples by ddPCR is valuable in determining virus shedding duration across different SARS-CoV-2 variants, informing transmission and disease control. Finally, testing saliva could overcome the detection of historic cases due to prolonged RNA swabbing past-infection and the unnecessary exclusion of those individuals from the workplace.

E-health technologies improve healthcare quality and disease management. The aim of this study was to develop a ketogenic diet management app as well as a website about this dietary treatment and to evaluate the benefits of giving caregivers access to various web materials designed for paediatric patients with refractory epilepsy. Forty families participated in the questionnaire survey, from January 2016 to March 2016. All caregivers were exposed to paper-based materials about the ketogenic diet, whereas only 22 received the app, called KetApp, and videos produced by dieticians. Caregivers with free access to web materials were more satisfied than the others with the informative material provided by the centre (p ≤ 0.001, Mann-Whitney test). Indeed, they showed a better attitude towards treatment, and they became more aware of dietary management in comparison to the control group (p ≤ 0.001). Moreover, caregivers provided with web materials were stimulated to pursue the treatment (p = 0.002) and to introduce it to their children and other people (p = 0.001). Additionally, caregivers supplied with web materials were more willing to help other families in choosing the ketogenic diet (p = 0.004). Overall, these findings indicate that web materials are beneficial for caregivers of paediatric patients with refractory epilepsy in our centres. Thus, the use of e-health applications could be a promising tool in the daily aspects of ketogenic diet management, and it is especially of value in the attempt to start or maintain the diet during the ongoing COVID-19 pandemic crisis.

Postural orthostatic tachycardia syndrome (POTS) negatively impacts quality of life. The excessive increase in cardiac sympathetic modulation during standing, which characterizes POTS patients, leads to many symptoms and signs of orthostatic intolerance. Little is known about the consequences of the disease on work performance and its relationship with individual autonomic profiles. Twenty-two POTS patients regularly engaged in working activity (20 females, age 36 ± 12 years) and 18 gender- and age-matched controls underwent a clinical evaluation and filled out the Work Ability Index (WAI) questionnaire. POTS patients completed the Composite Autonomic Symptom Score (COMPASS31) questionnaire, underwent continuous electrocardiogram, blood pressure and respiratory activity recordings while supine and during a 75° head-up tilt (HUT). A power spectrum analysis provided the index of cardiac sympatho-vagal balance (LF/HF). WAI scores were significantly reduced in POTS patients (29.84 ± 1.40) compared to controls (45.63 ± 0.53, p < 0.01). A significant inverse correlation was found between individual WAI and COMPASS31 scores (r = -0.46; p = 0.03), HUT increase in heart rate (r = -0.57; p = 0.01) and LF/HF (r = -0.55; p = 0.01). In POTS patients, the WAI scores were inversely correlated to the intensity of autonomic symptoms and to the excessive cardiac sympathetic activation induced by the gravitational stimulus.

Flu vaccination is recommended among healthcare workers (HCWs). The low vaccination coverage registered in our hospital among HCWs called for new engaging approaches to improve flu vaccination coverage. The aim of this study was to evaluate the efficacy of different strategies implemented during the last four years (2015-2019). A quasi-experimental study was conducted, involving almost 4000 HCWs each year. Starting from the 2015-2016 campaign, new evidence-based strategies were progressively implemented. At the end of each campaign, an evaluation of the vaccination coverage rate reached was performed. Moreover, during the last three campaigns, differences in coverage among job category, wards involved or not in on-site vaccination (OSV) intervention, age classes and gender were analyzed. An increasing flu vaccination coverage rate was registered, from 6% in 2015-2016 to almost 22% at the end of 2018-2019. The overall number of vaccinated HCWs increased, especially at younger ages. OSV strategy always leads to better results, and physicians always show a higher vaccination coverage than nurses and other HCWs. The implemented strategies were effective in achieving higher flu vaccination coverage among HCWs in our hospital and therefore can be considered valuable examples of good prevention practices in hospital settings.
