The Eye-tracking technology in the healthcare settings: an observational, cross sectional, multicenter study

Successful communication is considered an essential component of the quality of care and safety of the patient with Amyotrophic Lateral Sclerosis (ALS). Recent technology has provided alternative communication systems, including the Eye-tracking technology, which enables interaction with others in the more advanced stages of the disease. The aim of the study is to investigate patients' difficulties in using the eye tracker, their problem in obtaining the device and the clinical complications resulting from it. A "snowball sampling" method study was conducted from April to September 2020 until sample saturation. The results of the study demonstrate the countless difficulties in obtaining the eye- tracker, with long waiting times, which are not followed by adequate training in its correct use. Among the consequences linked to the use of this device, the most frequent were nystagmus (8.8%), onset of eyelid ptosis (16.2%) and the appearance of increased fatigue. 56.1% of the sample used the eye tracker to surf the Internet whereas 9.1% used it to write e-mails. Overall, the use of the eye tracker led to an improvement in overall quality of life (24%). In Conclusions, the Eye-tracking technology is a valuable device for Alternative Augmentative Communication (AAC) in ALS patients and can be used with good performance, therefore the need for information, training and improvement on this topic is essentia

Attitudes, knowledge and Practices of Nurses towards HIV/AIDS Patients. An Observational, Cross Sectional, Multicenter study

Background. Attitudes, knowledge and practices of nurses towards HIV/AIDS patients are of continuous interest, especially in developing countries. However, in Italy, this topic is still scarcely debated. Materials and methods. An observational, cross sectional, multicentre study was conducted on a sample of 144 nurses in two Italian Hospitals of the Puglia Region ("Vito Fazzi" Hospital in Lecce and "San Giuseppe da Copertino" Hospital in Copertino (Le)). Results. A large part of the sample (97.2%, n=140) stated that they never refused to take care of a patient with AIDS. Only 22.9%, (n=33), of the sample had attended a training course and almost half (63.2%, n=91) used the gloves regularly when performing blood samples or when administering therapy to patients. With regard to the assessment of HIV knowledge, the percentage of nurses who know the meaning of the terms " seropositive" (83.3%, n=120), "HIV-positive person" (91.7%, n=132) and "window period" (47.9%, n=69) decreased. Conclusions. The results of the study show that a non-negligible percentage of nurses could be considered at risk of infection due to non-routine use of gloves, incorrect handling of the patient's biological samples and not knowing how to decontaminate a surface with potentially infected blood

Anxiety, Depression and Post-Traumatic Stress Disorder in Physicians Compared to Nurses during the COVID-19 Pandemic: An Observational, Cross Sectional, Multicentric Study

(1) Background: The coronavirus pandemic has highlighted the precarious health situation of our country, thanks to the grueling workloads caused by understaffing and fear of contracting COVID-19. By considering this critical situation, frontline healthcare professionals who have been directly involved in the diagnosis, treatment, and care of SARS-CoV-2 patients are now at risk of developing psychological distress and other mental health symptoms, accomplices of the fear of contracting the COVID-19 and the exhausting workloads. (2) Methods: An observational, cross-sectional, multicenter study was conducted by administering an online questionnaire to all Italian physicians and nurses who worked during the COVID-19 pandemic. The questionnaire consists of socio-demographic characteristics, an assessment of anxiety levels with the State-Trait Anxiety Inventory (STAI), which also assessed trait and state anxiety, the Beck Depression Inventory (BDI) to evaluate the condition of depressive severity, and, finally, the Impact of Event Scale–Revised (IES–R), which was administered in order to quantify the post-traumatic stress disorder (PTSD) among the participants. (3) Results: A total of 770 Italian healthcare workers were enrolled in this study. Of these, 95 (12.30%) were physicians and 675 (87.70%) were nurses. By considering PTSD, anxiety, and depression levels between the physicians and nurses recruited, a significant difference was reported in the STAI-1 assessment, as both physicians and nurses reported slight and moderate levels (p = 0.033). (4) Conclusions: Physicians and nurses, who have been subjected to physical impoverishment, with the infinite physical forces spent to support the pace of work at the limits of the possible, but above all mental capacity, with the anxiety of having to face an unknown enemy, such as COVID-19. This has resulted in a significant increase in anxiety, depression, post-traumatic symptoms, and sleep disturbances, with possible repercussions not only on the quality of life of the physicians and nurses but also on the quality of assistance provided

Platinum salts in advanced breast cancer : a systematic review and meta-analysis of randomized clinical trials

Background: The interest in platinum salts in breast cancer (BC) therapy has been recently renewed as inhibition of DNA damage response may enhance the effects of DNA-damaging agents in BC tumors with high genomic instability. The present systematic review and meta-analysis of randomized trials were performed to assess the efficacy and safety of therapy with platinum salts in patients with locally advanced or metastatic (hereinafter advanced) BC. Methods: We searched PubMed, EMBASE, SCOPUS, Web of Science, the Cochrane Library, and CINAHL for phase II/III clinical trials that assessed efficacy of platinum-based therapy in patients with advanced BC. Pooled estimates of overall response rate (RR), median progression-free survival (PFS) and overall survival (OS) were computed using random or fixed effects models. Results: Data on 4625 patients from 23 phase II and III trials (11 with cisplatin, 11 with carboplatin, and 1 with either agents respectively) were analyzed. Estimates for RR, PFS, and OS were obtained from 23, 13, and 15 studies, respectively. Although at the cost of significantly increased fatigue, hematological and gastrointestinal toxicity, compared with non-platinum schemas, cisplatin, and carboplatin prolonged OS (HR 0.91; 95\ua0% CI 0.83\u20131.00, p\ua0=\ua00.04), PFS (HR 0.84; 95\ua0% CI 0.73\u20130.97, p\ua0=\ua00.01), and RR (HR 1.27; 95\ua0% CI 1.03\u20131.57, p\ua0=\ua00.03). Conclusions: Despite some limitations of the studies examined, including partial information on hormonal receptor and HER2 status, the use of platinum salts significantly prolonged OS, and PFS of patients with advanced BC with no unexpected toxicity

Machine Learning Models to Enhance the Berlin Questionnaire Detection of Obstructive Sleep Apnea in at-Risk Patients

The Berlin questionnaire (BQ), with its ten questions, stands out as one of the simplest and most widely implemented non-invasive screening tools for detecting individuals at a high risk of Obstructive Sleep Apnea (OSA), a still underdiagnosed syndrome characterized by the partial or complete obstruction of the upper airways during sleep. The main aim of this study was to enhance the diagnostic accuracy of the BQ through Machine Learning (ML) techniques. A ML classifier (hereafter, ML-10) was trained using the ten questions of the standard BQ. Another ML model (ML-2) was trained using a simplified variant of the BQ, BQ-2, which comprises only two questions out of the total ten. A 10-fold cross validation scheme was employed. Ground truth was provided by the Apnea–Hypopnea Index (AHI) measured by Home Sleep Apnea Testing. The model performance was determined by comparing ML-10 and ML-2 with the standard BQ in the Receiver Operating Characteristic (ROC) space and using metrics such as the Area Under the Curve (AUC), sensitivity, specificity, and accuracy. Both ML-10 and ML-2 demonstrated superior performance in predicting the risk of OSA compared to the standard BQ and were also capable of classifying OSA with two different AHI thresholds (AHI ≥ 15, AHI ≥ 30) that are typically used in clinical practice. This study underscores the importance of integrating ML techniques for early OSA detection, suggesting a direction for future research to improve diagnostic processes and patient outcomes in sleep medicine with minimal effort

Targeting DNA Replication before it Starts: Cdc7 as a Therapeutic Target in p53-Mutant Breast Cancers

Treatment options for triple-receptor negative (ER−/PR−/Her2−) and Her2-overexpressing (ER−/PR−/Her2+) breast cancers with acquired or de novo resistance are limited, and metastatic disease remains incurable. Targeting of growth signaling networks is often constrained by pathway redundancy or growth-independent cancer cell cycles. The cell-cycle protein Cdc7 regulates S phase by promoting DNA replication. This essential kinase acts as a convergence point for upstream growth signaling pathways and is therefore an attractive therapeutic target. We show that increased Cdc7 expression during mammary tumorigenesis is linked to Her2-overexpressing and triple-negative subtypes, accelerated cell cycle progression (P < 0.001), arrested tumor differentiation (P < 0.001), genomic instability (P = 0.019), increasing NPI score (P < 0.001), and reduced disease-free survival (HR = 1.98 [95% CI: 1.27–3.10]; P = 0.003), thus implicating its deregulation in the development of aggressive disease. Targeting Cdc7 with RNAi, we demonstrate that p53-mutant Her2-overexpressing and triple-negative breast cancer cell lines undergo an abortive S phase and apoptotic cell death due to loss of a p53-dependent Cdc7-inhibition checkpoint. In contrast, untransformed breast epithelial cells arrest in G1, remain viable, and are able to resume cell proliferation on recovery of Cdc7 kinase activity. Thus, Cdc7 appears to represent a potent and highly specific anticancer target in Her2-overexpressing and triple-negative breast cancers. Emerging Cdc7 kinase inhibitors may therefore significantly broaden the therapeutic armamentarium for treatment of the aggressive p53-mutant breast cancer subtypes identified in this study
