Objectives: (1) To describe ACPT implementation frequency in practice. (2) To assess associations of ACPT documentation with a) hospital care consumption, including systemic anti-tumor treatment in the last month(s) of life, and b) match between preferred and actual place of death, among oncology patients. Methods: A retrospective cohort study was performed. Data concerning ACPT documentation, hospital care consumption, and preferred and actual place of death were extracted from electronic patient records. Patients with completely documented ACPT (cACPT) and no ACPT were compared using multivariable logistic regression analyses. Results: ACPT was implemented in 64.5% (n = 793) of all deceased patients (n = 1230). In 17.6% (n = 216), preferred place of care or death was documented at least three months before death (cACPT). A cACPT was not associated with systemic anti-tumor treatment (Adjusted OR (AOR): 0.976; 95% CI: 0.642-1.483), but patients with cACPT had fewer diagnostic tests (AOR: 0.518; CI: 0.298-0.903) and less contacts with hospital disciplines (AOR: 0.545; CI: 0.338-0.877). In patients with cACPT, a match between preferred and actual place of death was found for 83% of the patients for whom the relevant information was available (n = 117/n = 141). In patients without ACPT, this information was mostly missing. Conclusion: Although the ACPT was implemented in two thirds of patients, timely documentation of preferred place of care or death is often missing. Yet, timely documentation of these preferences may promote out-hospital-death and save hospital care consumption.

The purpose of this study was to understand the occupational performance of parents with cancer and to understand if photo-elicitation would provide new insights into these experiences. In a semi-structured photo-elicitation interview, 36 participants living with and beyond cancer who had children under 18 years old shared and discussed photographs related to their parenting experiences. Transcribed interviews were analyzed using thematic analysis. Two main themes were identified. Parents shared how they (a) managed daily responsibilities and (b) maintained connection with their family. Across all types, stages and phases of the cancer continuum parents shared experiences related to maintaining child and family responsibilities and maintaining connection with their children. Photo-elicitation was an efficient and effective method to gather rich data from parents living with cancer. The results emphasize the clinical utility of using photo-elicitation to understand the occupational performance of parents throughout the cancer continuum of care.

Purpose: We aim to investigate the localization, visibility, and measurement of lung nodules in digital chest tomosynthesis (DTS).

Approach: Computed tomography (CT), maximum intensity projections (CT-MIP) (transaxial versus coronal orientation), and computer-aided detection (CAD) were used as location reference, and inter- and intra-observer agreement regarding lung nodule size was assessed. Five radiologists analyzed DTS and CT images from 24 participants with lung $\text{nodules}\ge 100{\mathrm{mm}}^3$ , focusing on lung nodule localization, visibility, and measurement on DTS. Visual grading was used to compare if coronal or transaxial CT-MIP better facilitated the localization of lung nodules in DTS.

Results: The majority of the lung nodules (79%) were rated as visible in DTS, although less clearly in comparison with CT. Coronal CT-MIP was the preferred orientation in the task of locating nodules on DTS. On DTS, area-based lung nodule size estimates resulted in significantly less measurement variability when compared with nodule size estimated based on mean diameter (mD) ( $p<0.05$ ). Also, on DTS, area-based lung nodule size estimates were more accurate ( $\mathrm{SEE}=38.7{\mathrm{mm}}^3$ ) than lung nodule size estimates based on mean diameter ( $\mathrm{SEE}=42.7{\mathrm{mm}}^3$ ).

Conclusions: Coronal CT-MIP images are superior to transaxial CT-MIP images in facilitating lung nodule localization in DTS. Most $\text{nodules}\ge 100{\mathrm{mm}}^3$ found on CT can be visualized, correctly localized, and measured in DTS, and area-based measurement may be the key to more precise and less variable nodule measurements on DTS.

Objective(s): Unmet needs of relatives of patients with advanced cancer not only reduce their own health-related quality of life, but may also negatively affect patients' health outcomes. The aim of this study was to assess changes in relatives' unmet needs of patients with advanced cancer in the last year of life and to identify differences in unmet needs by gender and type of relationship. Methods: Relatives of patients with advanced cancer in the Netherlands were included in a prospective, longitudinal, observational study. Relatives' unmet needs were measured every 3 months with an adapted version of the Problems and Needs in Palliative Care (PNPC) questionnaire Caregiver form (44 items, 12 domains). Questionnaires completed in the patients' last year of life were analyzed. Change of unmet needs in the last year, and differences in unmet needs by gender and type of relationship were analyzed. Results: A total of 409 relatives were included with a median of 4 unmet needs in the patient's last year. Unmet needs were most prevalent at all time points during the last year in the domains "caring for the patient" (highest need = 35%) and "psychological issues" (highest need = 40%). The number of unmet needs of relatives did not change significantly during the last year of life (P=.807). There were no significant differences in the number of unmet needs between male and female partners and between partners and other relatives. Conclusion: The most unmet needs for relatives were in the domains "caring for the patient" and "psychological issues." Professional support should focus on these items. Within these domains, it seems especially important that relatives get more knowledge and support about what scenarios to expect and how to deal with them.

Purpose: The endoscopic endonasal approach (EEA) has become the preferred treatment for pituitary tumors, with minimal sinonasal morbidity. However, patients with Cushing's disease (CD) may represent a subgroup with prolonged impairment of sinonasal quality of life (QOL).

Methods: We retrospectively identified patients with CD who underwent EEA at our institution. Control patients with non-functional tumors were matched by age, gender, and extent of EEA. The primary outcome was post-operative 22-item Sino-Nasal Outcome Test (SNOT-22) scores.

Results: Ten patients with CD met the selection criteria and 20 controls were selected for comparison. Nine of the CD patients achieved persistent endocrinologic remission post-operatively. Comparing the CD and control groups, there was no difference in post-operative SNOT-22 score at 1 or 3 months. At 6 months, SNOT-22 scores were significantly worse in the CD group (27.4 ± 21.6 vs. 2.8 ± 2.3, P = .039). SNOT-22 scores improved to normal from 1 to 6 months in the control cohort (P = .007), but not in the Cushing's group (P = .726). Morbidity was present across all SNOT-22 domains, but was highest in the sleep domain (P = .023). Only morbidity in the facial domain improved over time (P = .032).

Conclusions: Patients with CD have significantly prolonged postoperative sinonasal QOL impairment following EEA compared to patients with non-functioning tumors, who normalize within 6 months. In CD patients, only morbidity in the facial domain, likely related to post-operative pain and nasal packing, improved over time, while the sleep domain was the most affected.

Introduction: During the COVID-19 Pandemic, the use of digital devices during work activities has increased with important repercussions on the psychological and physical well-being of the employees. The aim of this study was to investigate the prevalence of musculoskeletal and visual disorders related to the use of computers and home workstation.

Methods: The study is a cross-sectional study. A checklist, from the National Institute of Health, was administered to white collar workers of a large international pharmaceutical company based in Italy.

Results: Our study showed that postural breaks have a protective effect on neck/shoulder pain (OR 0.32, CI 0.16-0.62), back and lower extremity pain (OR 0.35, CI 0.18-0.69), and eye burning (OR 0.50, CI 0.27-0.94) of study participants.

Conclusions: The research recommends that remote employees who often change their workstations should establish a suitable work environment and obtaining enough risk training from an occupational physician. This is essential for maintaining their mental and physical well-being.

Purpose: Chest tomosynthesis (CTS) has a relatively longer acquisition time compared with chest X-ray, which may increase the risk of motion artifacts in the reconstructed images. Motion artifacts induced by breathing motion adversely impact the image quality. This study aims to reduce these artifacts by excluding projection images identified with breathing motion prior to the reconstruction of section images and to assess if motion compensation improves overall image quality.

Approach: In this study, 2969 CTS examinations were analyzed to identify examinations where breathing motion has occurred using a method based on localizing the diaphragm border in each of the projection images. A trajectory over diaphragm positions was estimated from a second-order polynomial curve fit, and projection images where the diaphragm border deviated from the trajectory were removed before reconstruction. The image quality between motion-compensated and uncompensated examinations was evaluated using the image quality criteria for anatomical structures and image artifacts in a visual grading characteristic (VGC) study. The resulting rating data were statistically analyzed using the software VGC analyzer.

Results: A total of 58 examinations were included in this study with breathing motion occurring either at the beginning or end ( $n=17$ ) or throughout the entire acquisition ( $n=41$ ). In general, no significant difference in image quality or presence of motion artifacts was shown between the motion-compensated and uncompensated examinations. However, motion compensation significantly improved the image quality and reduced the motion artifacts in cases where motion occurred at the beginning or end. In examinations where motion occurred throughout the acquisition, motion compensation led to a significant increase in ripple artifacts and noise.

Conclusions: Compensation for respiratory motion in CTS by excluding projection images may improve the image quality if the motion occurs mainly at the beginning or end of the examination. However, the disadvantages of excluding projections may outweigh the benefits of motion compensation.

Background: The glycemic response to critical COVID-19 remains uncertain. We aimed to assess the association between COVID-19, insulin requirements, glycemic control, and mortality in intensive care unit (ICU) patients.

Methods: We conducted a retrospective observational study of 350 COVID-19 patients and 1067 non-COVID-19 patients admitted to the ICU. Insulin requirement was defined as the total units of exogenous insulin required to cover one gram of administered carbohydrates (insulin-to-carbohydrate ratio, ICR). We used multivariable generalized linear mixed-model (GLMM) analysis to assess the association of the interaction between COVID-19 and ICU-day with daily ICR, adjusted for fixed and time-dependent covariates. Glycemic control was assessed after stratification on diabetes and COVID-19. We used multivariable logistic regression analysis to assess the association between ICR and 90-day mortality.

Results: The mean (95% CI) of the mean daily ICR among patients without diabetes was 0.09 (0.08-0.11) U/g and 0.15 (0.11-0.18) U/g in the non-COVID-19 group and COVID-19 group (p = .01), respectively. In diabetes patients, the corresponding ICRs were 0.52 (0.43-0.62) U/g and 0.59 (0.50-0.68) U/g (p = .32). In multivariable GLMM analysis, the interaction between COVID-19 and ICU-day was independently associated with ICR (risk estimate 1.22, 95% CI 1.15-1.31, p < .001). COVID-19 was associated with higher hypoglycemia prevalence irrespective of diabetes status, higher average glucose levels, more pronounced glucose variability, and a lower proportion of glucose values within target range among patients without diabetes. On multivariable logistic regression analysis, the adjusted odds ratio for 90-day mortality was 1.77 (95% CI 0.94-3.34, p = .076) per one unit increase in mean ICR.

Conclusion: In our cohort of ICU patients, COVID-19 was associated with higher daily insulin requirements per gram of administered carbohydrates, and worse glycemic control. We found no robust association between ICR and increased odds of death at 90 days.

Alcohol contributes to higher fall risk in people living with HIV (PLWH), yet fall prevention trials for PWH with alcohol use are lacking. To assess the feasibility of conducting a randomized controlled trial of a 10-week online fall prevention intervention tailored for PLWH with alcohol use. The intervention consisted of weekly virtual group discussions, individual phone check-ins, and home exercises. Of those eligible, 53.5% (23/43) enrolled (12 to the intervention and 11 to control). Mean age was 58 years; 82.6% had a past 6-month fall; 65.2% had alcohol use disorder; and 95.7% completed postintervention assessments. The intervention was highly rated (Client Satisfaction Questionnaire-8 score M = 30.4, SD = 1.6) with a wide range of group and individual phone session attendance. Preliminary analyses suggest the intervention may reduce the odds of falling and alcohol use frequency. Findings support the feasibility of a larger randomized trial.
