Examination of Indoor Mobile Mapping Systems in a Diversified Internal/External Test Field

Nowadays, simultaneous localization and mapping (SLAM) algorithms support several commercial sensors which have recently been introduced to the market, and, like the more common mobile mapping systems (MMSs), are designed to acquire three-dimensional and high-resolution point clouds. The new systems are said to work both in external and internal environments, and completely avoid the use of targets and control points. The possibility of increasing productivity in three-dimensional digitization projects is fascinating, but data quality needs to be carefully evaluated to define appropriate fields of application. The paper presents the analytical measurement principle of these indoor mobile mapping systems (IMMSs) and the results of some tests performed on three commercial systems. A common test field was defined in order to acquire comparable data. By taking the already available terrestrial laser scan survey as the ground truth, the datasets under examination were compared with the reference and some assessments are presented which consider both quantitative and qualitative aspects. Geometric deformation in the final models was computed using the so-called Multiscale Model to Model Cloud Comparison (M3C2) algorithm. Cross sections and cloud to mesh (C2M) distances were also employed for a more detailed analysis. The real usability assessment is based on the features of recognizability, double surface evidence, and visualization effectiveness. For these evaluations, comparative images and tables are presented. © 2018 by the authors

Italian nurses’ experiences of the COVID-19 pandemic through social media: A longitudinal mixed methods study of Internet posts

Objective: To examine the experience of Italian nurses posted on social media and discover changes, if any, over the waves. Methods: A mixed methods study reported according to the Good Reporting of a Mixed Methods Study criteria. All narratives (texts, letters and interviews) posted by Italian nurses from February 2020 to May 2020 (first wave) and from October 2020 to May 2021 (second/third wave) on the five most famous Italian professional social media platforms. The data were analysed qualitatively (first wave) and then quantitatively (second/third wave). Results: A total of 380 narratives (202,626 words, 2510 quotes) were posted in the first wave, and 161 (68,388 words, 835 quotes) in the second/third wave. In the first wave, the following five themes emerged: (a) ‘sharing what is happening within myself’ (891; 35.5%); (b) ‘experiencing unprecedented working conditions’ (749; 29.8%); (c) ‘failing to rehabilitate the image of nurses in society’ (376; 15%); (d) ‘experiencing a deep change’ (253; 10.1%) and (e) ‘do not abandon us’ (241; 9.6%). The same themes and subthemes also emerged in the second/third wave with some significant differences, indicating changes in the lived experience of nurses. Moreover, in the second/third wave, a new theme emerged: ‘experiencing the mixed emotions towards jabs’. Conclusions: By analysing their posts, Italian nurses continue to face challenges during the COVID-19 pandemic, with changes in their lived experiences across the waves. Governments, nursing associations and health care organizations should consider these changes to design policies to prevent the further loss of nurses

One Word to Describe My Experience as a COVID-19 Survivor Six Months after Its Onset: Findings of a Qualitative Study

The COVID-19 pandemic emotionally affected the lives of patients cared for in different settings. However, a comprehensive view of the whole experience as lived by survived patients, from the onset of the disease and over time, is substantially unknown to date. A descriptive qualitative design was implemented according to the Standards for Reporting Qualitative Research. Adult patients (=1067) cared for during the first wave (March/April 2020) capable of answering an interview and willing to participate were interviewed (=397) by phone with an interview guide including open- and closed-ended questions. In this context, they were asked to summarise with a metaphor their entire COVID-19 experience at six months. Then, the emotional orientation (positive, neutral, or negative) of the metaphors expressed was identified. The participants were mainly female (206; 51.9%), with an average age of 52.6 years (CI 95% 50.4-53.6), reporting a mild severity of COVID-19 disease at the onset (261; 65.7%) and the perception of being completely healed (294; 70%) at six months. The patients summarised their experiences mainly using negative-oriented (248; 62.5%) metaphors; only 54 (13.6%) reported positive-oriented metaphors and a quarter (95; 23.95) neutral-oriented metaphors. Nearly all positive-oriented metaphors were reported by patients with symptoms at the onset (53; 98.1%), a significantly higher proportion compared to those reporting negative- (219; 88.3%) and neutral-oriented (78; 82.1%) metaphors (p = 0.014). While no other clinical features of the disease were associated, among females, significantly more negative-oriented metaphors emerged. Moreover, neutral-oriented metaphors were reported by younger patients (49.5 years, CI 95% 64.11-52.92) as compared to those negative and positive that were reported by more mature patients (53.9; CI 95% 52.04-55.93 and 54.8; CI 95% 50.53-59.24, respectively) (p = 0.044). Nurses and healthcare services require data to predict the long-term needs of patients. Our findings suggest that, for many patients, the COVID-19 lived experience was negative over time

Vaccine Hesitancy among Italian Patients Recovered from COVID-19 Infection towards Influenza and Sars-Cov-2 Vaccination

We aimed to assess the attitude towards influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations among coronavirus disease 2019 (COVID-19) recovered patients. We performed a cross-sectional study consisting of a standardized telephone interview carried out between September and November 2020 targeting a cohort of adult in- and out-patients that had recovered from COVID-19 after the first wave (March-May 2020) at Udine Hospital (Italy). Overall, 599 people participated (320 female, median age 53 years) and most had experienced an acute COVID-19 with mild illness (409, 68.3%). The majority were hesitant or undecided towards influenza (327, 54.6%) and SARS-CoV-2 (353, 59.2%) vaccines. Older age, public work exposure, and previous 2019 flu shots were the main factors associated with a positive attitude toward both vaccinations (p < 0.05). Being hospitalized during the acute COVID-19 phase was associated with the willingness to get a flu shot (94/272, 34.5%) but not SARS-CoV-2 vaccine (70/244, 28.7%). Vaccine hesitancy is diffuse and multifactorial also among COVID-19 recovered

The Fall in Antibody Response to SARS-CoV-2: a Longitudinal Study of Asymptomatic to Critically Ill Patients Up to 10 Months after Recovery

The aim of this study was to assess the long-term dynamics and factors associated with the serological response against the severe acute respiratory syndrome coronavirus 2 after primary infection. A prospective longitudinal study was conducted with monthly serological follow-up during the first 4 months, and then at 6, 8, and 10 months after the disease onset of all recovered adult in- and outpatients with coronavirus disease 2019 (COVID-19) attending Udine Hospital (Italy) during the first wave (from March to May 2020). A total of 546 individuals were included (289 female, mean age 53.1 years), mostly with mild COVID-19 (370, 68.3%). Patients were followed for a median of 302 days (interquartile range, 186 to 311). The overall seroconversion rate within 2 months was 32% for IgM and 90% for IgG. Seroreversion was observed in 90% of patients for IgM at 4 months and in 47% for IgG at 10 months. Older age, number of symptoms at acute onset, and severity of acute COVID-19 were all independent predictors of long-term immunity both for IgM (beta, linear regression coefficient, 1.10, P = 0.001; beta 5.15 P = 0.014; beta 43.84 P = 0.021, respectively) and for IgG (beta 1.43 P &lt; 0.001; beta 10.46 P &lt; 0.001; beta 46.79 P, 0.001, respectively), whereas the initial IgG peak was associated only with IgG duration (beta 1.12, P &lt; 0.001). IgM antibodies disappeared at 4 months, and IgG antibodies declined in about half of patients 10 months after acute COVID-19. These effects varied depending on the intensity of the initial antibody response, age, and burden of acute COVID-19

Patients' experience of haemorrhagic cystitis after Haematopoietic Stem Cell Transplantation: Findings from a phenomenological study

Haemorrhagic cystitis (HC) is a severe complication of haematopoietic stem cell transplantation (HSCT), which significantly affects patients' quality of life. However, no qualitative studies have described to date the experience of patients who have developed this complication. Therefore, the aim of this interpretative phenomenological study performed on 2019 was to explore the experience of patients who developed HC after HSCT

Patient experiences of systemic lupus erythematosus: Findings from a systematic review, meta\u2010summary and meta\u2010synthesis

OBJECTIVE: To explore the experience of patients with systemic lupus erythematosus (SLE). METHODS: A systematic review of qualitative studies published in English in the past 10 years and identified through the PubMed, CINAHL, Scopus, and Web of Science databases was performed following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. The methodologic quality of each included study was assessed using the Critical Appraisal Screening Programme tool. Study findings were then subjected to a meta‐summary and meta‐synthesis. RESULTS: Twenty‐six studies with a good overall methodologic quality were included, documenting the experience of 565 adult patients (95% women). A total of 17 codes emerged, summarizing the life experience of SLE patients; the most and least frequent codes in the meta‐summary were “feeling not as I usually do” (69.2%) and “having wishes” (7.7%). The codes were then categorized into 5 main themes, summarizing the experience of living with SLE: 1) “experiencing waves of emotions due to the unpredictable nature of the disease,” 2) “trying to live an ordinary life,” 3) “listening to and obeying the body's limitations,” 4) “reviewing my life projects,” and 5) “dealing with future uncertainties.” CONCLUSION: Several qualitative studies have been published to date using good methodologic approaches. According to the findings, SLE negatively impacts patient experiences by affecting multiple dimensions of their daily lives, with fatigue and pain as the most frequent symptoms

Factors triggering the progressive detachment of nurses toward the fundamental needs of patients: findings from a qualitative study

: The progressive desensitization of nurses in relation to fundamental needs (FNs) has been documented in anecdotical, scientific, and policy literature with nurses spending limited time at the bedside, thus affecting the quality of care and clinical outcomes. A potential reason that has been recognized is the limited nursing staff available in the units. However, other cultural, social, and psychological factors which have not been investigated to date may have a role in triggering the phenomenon. To investigate nurses' perceptions of the reasons that progressively detach clinical nurses from the FNs of patients, was the main intent of the study. In 2020, a qualitative study based on grounded theory following the Standards for Reporting Qualitative Research guidelines was performed. Purposeful sampling was adopted, by including 22 clinical nurses designated as 'good nurses' according to the perception of nurses working in executive and academic position. All agreed to be interviewed face-to-face. The detachment of nurses from the patients' FNs has been explained by three main factors that are interconnected: namely 'Being personally and professionally convinced regarding the role of FNs', 'Being progressively detached from the FNs', and 'Being forced to be detached from FNs'. Nurses also identified a category including strategies aimed at preventing detachment and 'Rediscovering the FNs as the core of nursing'. Nurses are personally and professionally convinced about the relevance of the FNs. However, they distance themselves from the FNs due to: (a) factors mainly attributable to internal personal and professional forces, such as the emotional fatigue that daily work entails; and (b) external forces related to the work environment where nurses work. To prevent this detrimental process that may result in negative outcomes for patients and their relatives, several strategies at the individual, organizational, and educational levels should be implemented

Using Metaphors to Understand Suffering in COVID-19 Survivors: A Two Time-Point Observational Follow-Up Study

Accumulating evidence indicates that the COVID-19 pandemic carries risks to psychological health and represents a collective traumatic experience with consequences at the social, economic, and health levels. The primary aim of this study was to collect ongoing COVID-19 survivors’ pandemic-related experiences as expressed through the use of metaphors; the secondary aim was to explore socio-demographic variables associated with the metaphor orientation as negative, positive or neutral. An observational follow-up survey was conducted and reported according to the STROBE guidelines. Patients ≥ 18 years, who were treated for COVID-19 during the first wave (March/April 2020) and who were willing to participate in a telephone interview were involved and asked to summarize their COVID-19 experience as lived up to 6 and 12 months in a metaphor. A total of 339 patients participated in the first (6 months) and second (12 months) data collection. Patients were mainly female (51.9%), with an average age of 52.9 years (confidence interval, CI 95% 51.2–54.6). At 6 months, most participants (214; 63.1%) used a negative-oriented metaphor, further increasing at 12 months (266; 78.5%), when they used fewer neutral-/positive-oriented metaphors (p < 0.001). At the 6-month follow-up, only three individual variables (female gender, education, and experiencing symptoms at the COVID-19 onset) were significantly different across the possible metaphor orientation; at 12 months, no individual variables were significantly associated. This study suggests increasingly negative lived experiences over time and the need for personalized healthcare pathways to face the long-term traumatic consequences of COVID-19

Lessons learnt while designing and conducting a longitudinal study from the first Italian COVID-19 pandemic wave up to 3 years

Abstract Background Several scientific contributions have summarized the “lessons learnt” during the coronavirus disease 2019 (COVID-19) pandemic, but only a few authors have discussed what we have learnt on how to design and conduct research during a pandemic. The main intent of this study was to summarize the lessons learnt by an Italian multidisciplinary research group that developed and conducted a longitudinal study on COVID-19 patients infected during the first wave in March 2020 and followed-up for 3 years. Methods A qualitative research approach embedded into the primary CORonavirus MOnitoRing study (CORMOR) study was developed, according to the the consolidated criteria for reporting qualitative research. Multiple data collection strategies were performed: each member was invited to report the main lessons learnt according to his/her perspective and experience from the study design throughout its conduction. The narratives collected were summarized and discussed in face-to-face rounds. The narratives were then thematically analysed according to their main topic in a list that was resent to all members to check the content and their organization. The list of the final “lessons learnt” has been agreed by all members, as described in a detailed fashion. Results Several lessons were learnt while designing and conducting a longitudinal study during the COVID-19 pandemic and summarised into ten main themes: some are methodological, while others concern how to conduct research in pandemics/epidemics/infectious disease emergencies. Conclusions The multidisciplinary approach, which also included patients’ perspective, helped us to protect the consistency and quality of the research provided in pandemic times. The lesson learnt suggest that our research approach may benefit from changes in education, clinical practice and policies
