The Usefulness of Virtual Reality in Symptom Management during Chemotherapy in Lung Cancer Patients: A Quasi-Experimental Study.

Background: Virtual reality (VR) emerges as a promising non-pharmacological intervention for managing symptoms and providing distraction during chemotherapy. This study aims to assess VR's effectiveness on cancer-related symptoms, vital signs, and the patients' perception of chemotherapy in lung cancer patients. Methods: A quasi-experimental study was conducted on 100 patients. Participants were allocated into an intervention group (n = 55), which experienced immersive VR, and a comparison group (n = 45), which received usual care. Data were collected through questionnaires and checklists, including feedback on the VR experience, pain, vital signs, and common cancer symptoms, assessed through the Edmonton Symptom Assessment Scale. Results: VR had a significant impact on reducing the perception of chemotherapy length. Patients reported high levels of satisfaction and tolerability. No adverse events were observed. VR did not have significant influence on pain intensity or vital signs. The only exceptions were oxygen saturation, where a significant difference (p = 0.02) was reported, and the perception of chemotherapy duration. Conclusions: As a non-pharmacological intervention, VR proves to be beneficial in minimizing the perceived length of chemotherapy sessions for lung cancer patients, enhancing their overall treatment experience. The intervention was found to be a safe, feasible, and well-accepted distraction technique. Future research should explore VR's potential effects on a wider range of symptoms and evaluate its impact on long-term outcomes.

Olfactory Dysfunctions and Chronic Kidney Disease: A Scoping Review.

Chronic kidney disease (CKD) represents a significant global public health challenge. Among the various clinical complications associated with CKD, olfactory dysfunction has been identified as a factor that substantially affects the quality of life of patients. This study aims to systematically explore the prevalence, implications, and therapeutic avenues of anosmia in CKD patients. This scoping review utilized the Arksey and O'Malley framework, incorporating the Joanna Briggs Institute methodology, and followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. The research question, formulated using the PIO framework, guided a thorough search of databases PubMed/Medline, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Cochrane Library and gray literature sources. Eligibility criteria focused on studies involving CKD patients with olfactory dysfunctions. From an initial pool of 832 articles, 17 studies met the criteria, providing insights into olfactory alterations in 4,025 CKD patients. The data that have been reported, define that 55,34% of the sample experienced olfactory changes and the 8.5% experienced anosmia. This review revealed a complex interplay of factors contributing to olfactory alterations, including uremic toxins, dialysis procedures, electrolyte imbalances, and malnutrition. Findings suggested the potential recovery of olfactory function following kidney transplantation. Various assessment tools were utilized, with the University of Pennsylvania Smell Identification Test and Sniffin' Sticks emerging as the primary instruments. The observed variability in findings highlights the need for continued research to understand the mechanisms, enhance therapies, and improve quality of life for CKD patients with olfactory dysfunctions. Future studies should employ standardized methods, explore new assessment tools, and prioritize longitudinal assessments to advance our understanding and management of olfactory dysfunctions in this population.

Pharmacological strategies and nutritional supplements for managing dysgeusia among chemotherapy patients: A systematic review.

BACKGROUND/OBJECTIVE: Among the side effects of chemotherapy, there is dysgeusia, which is an alteration or damage to the taste perception that negatively impacts the biopsychosocial sphere of the patient. Therefore, it is important to recognize and manage it appropriately. The objective of this study is to identify clinical pharmacological strategies to reduce dysgeusia in chemotherapy patients. METHODS: A systematic literature review was conducted following the PRISMA guidelines between February and May 2023, utilizing PubMed, Embase, Cochrane Library, CINAHL, and the British Nursing Database. Methodological quality and bias risk assessment were performed using the JBI framework, while evidence certainty was evaluated using the Oxford OCEBM methodology. RESULTS: Out of 1225 consulted records, 12 articles were included. The results underscore the efficacy of diverse pharmacological interventions in mitigating dysgeusia among chemotherapy patients. These include zinc supplementation with a daily dosage ranging between 50 and 220 mg (p ≤ 0.005), lactoferrin at 250 mg thrice daily (p < 0.001), delta-9-tetrahydrocannabinol at 2 mg per day (p < 0.05), and cannabidiol at 150 mg per day (p = 0.04). All studies analysed showed a low risk of bias. The zinc and Delta-9-Tetrahydrocannabinoid treatment proved particularly promising, compared to the other treatments considered, where sample sizes were smaller and the placebo effect was not always clear. CONCLUSION: Among the various pharmacological strategies identified, those that appear most promising concern the integration of zinc and Delta-9-Tetrahydrocannabinoid. Future studies should further explore the treatments identified in this review to expand the evidence base in this relatively underexplored field.

The Italian Validation of the Healthcare Professional Humanization Scale for Nursing.

Purpose: The Healthcare Professional Humanization Scale (HUMAS) is a measure of the evaluation of the humanization of care in nursing professions. Despite being validated for the Spanish language, there still needed validation in Italian, which seems essential considering the cultural differences. Aim: We aimed to test the validity and reliability of the HUMAS with an Italian sample of registered nurses. Methods: The present study used cross-sectional data from 300 nurses that completed the survey. The study's main phases were (a) construction of the Italian version; (b) testing and analyzing the psychometric properties of the scale. The exploratory factor analysis and the Content Validity Index (CVI) were performed. Cronbach's alpha and test-retest were used to determine the reliability. Findings: The final Italian version of HUMAS (HUMAS-I) comprised 19 items grouped into five correlated latent factors, accounting for 68.4% of the variance. Additionally, it exhibited a satisfactory Cronbach's alpha for each latent component and an average CVI for the entire scale of 0.68. Conclusions: The HUMAS-I shows acceptable psychometric proprieties as the original Spanish version. Therefore, it could be an advantageous instrument for use in nursing practice and research.

Systematic review of clinical practice guidelines and systematic reviews: A method for conducting comprehensive analysis.

A systematic review (SR) is a research method for synthesizing evidence on a specific topic. Among the various types of systematic reviews, there are SRs of guidelines (CPGs) and SRs of SRs. Traditionally, they are limited to just one type of secondary evidence. This paper introduces an innovative SR methodology that combines CPGs and SRs to improve evidence synthesis and overcome the limitations of isolated use. Essential steps that should always precede the actual research process include registering the research protocol, formulating research questions and setting inclusion/exclusion criteria. Using the PRISMA protocol for comprehensive database searches, it's crucial to combine keywords with boolean operators and remove duplicates. The eligibility of studies should be assessed by selecting potentially relevant articles through an initial screening of titles and abstracts, followed by a meticulous analysis of the full-texts. Rigorous evidence evaluation tools, such as AGREE II for CPGs and AMSTAR 2 for SRs, and the double reviewer approach ensure high-quality selections. Additionally, converting summarized results into percentages and applying statistical analyses facilitate interpretation and improve the reliability of rater assessments. A further characteristic of this methodology is its adaptability to the evolution of healthcare research.

Utilization and effects of security technologies in mental health: A scoping review.

Violence in healthcare is an urgent and increasing issue. Mental health settings are particularly affected, with severe negative impacts on staff, patients, and organizations. Security technologies could help maintain and improve safety in this field. However, knowledge of their utilization and effectiveness in mental health is lacking. A scoping review was conducted using the methodology recommended by the Joanna Briggs Institute to map research on the utilization and effects of security technologies in mental health, identify how research is currently performed, and highlight gaps in the existing knowledge. Literature search for peer-reviewed publications was performed on PubMed, CINAHL, PsycInfo, Embase, and Scopus. Following the screening process and the eligibility criteria, 22 articles were included in this review. The publication range was 2002-2020, many studies were surveys, and European countries were the most investigated, especially the United Kingdom. Overall, the use of 10 different technologies was reported 46 times. The most represented category was alarms, followed by video cameras, other technologies (such as wearable sensors), and metal detectors. More than half of the included papers reported positive effects of these measures on safety. This review indicates that several security technologies are available in mental health settings, with encouraging positive safety outcomes for both patients and healthcare professionals, especially nurses. However, research on the topic is still emerging, with a limited number of sources and a few high-quality designed studies. Therefore, future research should focus on producing evidence on the availability and effectiveness of these measures in mental health settings across countries.
