Skin Hydration Measurement: Comparison Between Devices and Clinical Evaluations.

BACKGROUND: The need for an objective method for measuring skin hydration levels is becoming increasingly important. Various devices with different measuring principles for assessing skin hydration have been developed and are widely used. OBJECTIVE: This study aimed to investigate the reproducibility and correlation between clinical evaluation and skin hydration measurement devices that are the most widely used in the field. METHODS: A prospective comparative clinical trial was conducted on 184 healthy volunteers. Skin hydration levels were measured using the Corneometer (CM820) and hydration probe (HP: DermaLab Combo) at 3 points: the ventral forearm, the dorsal forearm, and the shin. We used the intraclass correlation coefficient (ICC) to evaluate the reproducibility and Pearson's correlation coefficient (PCC) to evaluate the correlation of each measurement. Simple linear regression was used to analyze the Corneometer and HP skin hydration value changes according to changes in xerosis severity scale (XSS) values, which were evaluated by clinicians. RESULTS: Both the Corneometer and HP showed significant, excellent reproducibility (ICC for Corneometer: 0.954-0.971, ICC for HP: 0.980-0.986) and significant high positive correlations (PCC: 0.708-0.737) regardless of the measurement site. Both devices showed negative regression coefficients in all measurement sites in XSS analysis, but this was not statistically significant. CONCLUSION: The Corneometer and HP were both accurate and objective skin hydration measuring devices, regardless of the measurement site. Using reliable and objective devices such as the Corneometer or HP can aid in understanding an individual's skin condition and making more informed decisions for skin care.

Open or closed: Experience of head and neck radiotherapy masks - A mixed-methods study.

INTRODUCTION: In radiotherapy for head and neck cancer, a mask is used to immobilise the head and shoulders. An open mask that does not cover the face is expected to cause less anxiety, but there is need to further investigate the patients' experience of open versus closed masks. Therefore, the aim of this study is to evaluate patient preferences for open or closed masks and whether an open mask can reduce discomfort and anxiety for patients. METHODS: Twenty participants were treated in alternating weeks using open and closed masks. Their distress was evaluated through semi-structured interviews and patient-reported outcome measures. RESULTS: When using the open mask, it took longer to position the patient correctly. The closed mask felt more confining and could induce a sense of claustrophobia. Participants employed both internal and external strategies to cope with the stressful situation. The Hospital Anxiety and Depression Scale (HADS) showed a significant reduction in anxiety over time during the treatment period, but no significant difference between the masks. When participants chose which mask to use for the final treatments, 12 chose the open mask, while 8 chose the closed mask. In addition to the 20 analysed participants, two participants withdrew from the study because they could only tolerate the open mask, one due to anxiety and the other due to swelling. CONCLUSIONS: The open mask seems to provide a less confined experience but may lead to greater difficulties in achieving the correct treatment position. While both masks can be viable options for most patients, some cannot tolerate closed masks but do tolerate open masks.

Reduction of the acquisition time needed to obtain somatosensory evoked potentials by estimation of the required averaging sweep count by an algorithm.

Somatosensory evoked potentials are frequently acquired by stimulation of the median or tibial nerves (mSEPs and tSEPs) for intraoperative monitoring of sensory pathways. Due to their low amplitudes it is common practice to average 200 or more sweeps to discern the evoked potentials from the background EEG. The aim of this study was to investigate if an algorithm designed to determine the lowest sweep count needed to obtain reproducible evoked potentials in each patient significantly reduces the median necessary sweep count to under 200. 30 patients undergoing spinal surgery at the Department of Neurosurgery were included in the study. Beginning with a sweep count of 200 an algorithm was designed to determine the lowest sweep count that yielded reproducible evoked potentials in each patient. By this algorithm the minimal sweep count was determined in 15 patients for mSEPs and in 15 patients for tSEPs. The required sweep count was below 200 in 14 of 15 patients for mSEPs (93.3%) with a mean sweep count of 56 ± 51. For tSEPs the sweep count was below 200 in 11 of 15 patients (73.3%) with a mean sweep count of 106 ± 70 (mean ± SD). The calculated mean time to average the potentials could thereby be reduced from 48.8s to 13.7s for mSEPs and from 48.8s to 25.9s for tSEPs. The proposed algorithm allowed sweep count and acquisition time reduction in roughly 90% of all patients for mSEPs and in 70% of all patients for tSEPs.

Surgeon perspectives on preference cards and environmental stewardship.

BACKGROUND: Refinement of surgical preference cards may reduce waste from surgery. This study aimed to characterize surgeon perceptions and practices regarding preference card maintenance, identify barriers to updating preference cards, and explore whether opinions on environmental stewardship relate to preference card maintenance. METHODS: This was a mixed methods survey performed at a single tertiary academic medical center. Surgeons completed questions on accuracy, frequency of updates, and perceived environmental impact of their preference cards. Responses were compared between early career and mid-to late-career surgeons using Kruskal-Wallis, chi-squared, and Fisher's exact tests. RESULTS: The response rate was 46.4% (n = 89/192). Among respondents, 46.1% (n = 41/89) rarely or never updated preference cards. Nearly all (98.9%, n = 87/88) said some of their cases had unused items on their cards. Most (87.6%, n = 78/89) made updates via verbal requests. Unfamiliar processes (83.7%, n = 72/86) and effort required (64.0%, n = 55/86) were viewed as barriers to card maintenance. Most agreed that more frequent updates would reduce waste (80.5%, n = 70/87), but respondents did not feel knowledgeable about the environmental impact of items on their cards (62.1%, n = 54/87). Mid-to late-career surgeons were less likely to update their cards annually or more often compared to early career surgeons (18.9%, n = 7/37 vs. 57.1%, n = 24/42, p < 0.001). No other responses varied significantly between early career and mid-to late-career surgeons. CONCLUSIONS: Surgeons acknowledged the utility of preference card maintenance in environmental stewardship, but unfamiliar systems and perceived effort hindered preference card review. Greater attention to preference card maintenance would promote environmentally sustainable practices in surgery.

Effectiveness of mixed reality-based rehabilitation on hands and fingers by individual finger-movement tracking in patients with stroke.

BACKGROUND: Mixed reality (MR) is helpful in hand training for patients with stroke, allowing them to fully submerge in a virtual space while interacting with real objects. The recognition of individual finger movements is required for MR rehabilitation. This study aimed to assess the effectiveness of updated MR-board 2, adding finger training for patients with stroke. METHODS: Twenty-one participants with hemiplegic stroke (10 with left hemiplegia and 11 with right hemiplegia; nine female patients; 56.7 ± 14.2 years of age; and onset of stroke 32.7 ± 34.8 months) participated in this study. MR-board 2 comprised a board plate, a depth camera, plastic-shaped objects, a monitor, a palm-worn camera, and seven gamified training programs. All participants performed 20 self-training sessions involving 30-min training using MR-board 2. The outcome measurements for upper extremity function were the Fugl-Meyer assessment (FMA) upper extremity score, repeated number of finger flexion and extension (Repeat-FE), the thumb opposition test (TOT), Box and Block Test score (BBT), Wolf Motor Function Test score (WMFT), and Stroke Impact Scale (SIS). One-way repeated measures analysis of variance and the post hoc test were applied for the measurements. MR-board 2 recorded the fingers' active range of motion (AROM) and Dunnett's test was used for pairwise comparisons. RESULTS: Except for the FMA-proximal score (p = 0.617) and TOT (p = 0.005), other FMA scores, BBT score, Repeat-FE, WMFT score, and SIS stroke recovery improved significantly (p < 0.001) during MR-board 2 training and were maintained until follow-up. All AROM values of the finger joints changed significantly during training (p < 0.001). CONCLUSIONS: MR-board 2 self-training, which includes natural interactions between humans and computers using a tangible user interface and real-time tracking of the fingers, improved upper limb function across impairment, activity, and participation. MR-board 2 could be used as a self-training tool for patients with stroke, improving their quality of life. TRIAL REGISTRATION NUMBER: This study was registered with the Clinical Research Information Service (CRIS: KCT0004167).

Let us talk about mistakes.

Unfortunately, errors and mistakes are part of life. Errors and mistakes can harm patients and incur unplanned costs. Errors may arise from various sources, which may be classified as systematic, latent, or active. Intrinsic and extrinsic factors also contribute to incorrect decisions. In addition to cognitive biases, our personality, socialization, personal chronobiology, and way of thinking (heuristic versus analytical) are influencing factors. Factors such as overload from private situations, long commuting times, and the complex environment of information technology must also be considered. The objective of this paper is to define and classify errors and mistakes in radiology, to discuss the influencing factors, and to present strategies for prevention. Hierarchical responsibilities and team "well-being" are also discussed.

Evaluating soft collars in pre-hospital cervical spine immobilisation: A cohort study on neurological outcomes, patient comfort and paramedic perspectives.

OBJECTIVE: Cervical spinal immobilisation procedures often include rigid cervical collars which, despite associated complications, may provide less immobilisation than previously thought. The present study reports the incidence of worsening neurological outcomes following soft collar application, and additionally reports patient comfort, compliance with spinal immobilisation, and paramedic perspectives on usage. METHODS: This was an observational cohort study conducted in selected metropolitan and regional areas of NSW Ambulance between 1 May 2022 and 31 March 2023. Soft collars were used exclusively in place of rigid collars. The SPEED (SPinal Emergency Evaluation of Deficits) tool was used to evaluate new or worsening neurological deficits following pre-hospital soft collar application. Secondary outcomes included patient-reported comfort of the device, and paramedic assessment of efficacy. RESULTS: Overall, 2098 soft collars were applied, of which 74 patients (3.5%) were subsequently found to have a cervical spine injury. Eight patients had a spinal cord injury, of which two experienced a worsening neurological deficit after soft collar application. In both instances, comprehensive case reviews determined that this was unlikely to have been attributable to the soft collar. The majority of patients found the soft collar comfortable, and they were well-tolerated by patients who generally complied with immobility directions. Paramedics found the collar easy to apply, and felt it assisted in minimising patient movement. CONCLUSIONS: Pre-hospital use of soft collars does not appear to increase the risk of significant injury. Patients found these devices relatively comfortable, and clinicians reported overall ease of use with good patient compliance with immobility directives.

[Implementing an operating room pharmacy satellite in an university hospital]. / Mise en place d'une antenne pharmaceutique de blocs opératoires dans un centre hospitalier universitaire.

OBJECTIVES: An operating room pharmaceutical unit centralizes medical devices and drugs for various surgical specialities. The aim of this work is to present the methodology used in our establishment to set up the operating room pharmaceutical unit. METHODS: This approach involved the formation of multi-professional working groups. The needs of operating theatres were defined based on an analysis of healthcare product consumption and stock inventories. Material sheets were defined for each procedure. On the basis of simulations, material supply arrangements were selected, specifying material flows, equipment, workstations and information systems. RESULTS: Over 3200 healthcare product references were identified and 862 equipment files were created. Local stocks have been limited to medical trolleys for nursing staff. Emergency operating packs have been deployed for unforeseen operations. Cabinets have been dedicated to transporting re-sterilizable medical devices, and carts have been purchased for programmed operating packs. The equipment is made available by logistics agents and pharmacy assistants under pharmaceutical responsibility. CONCLUSIONS: This innovative approach is a model for facilities desiring to centralize and secure the logistics of healthcare products in the operating room. Ongoing adjustments will be required to meet new operating rooms needs.

A Rapid Point-of-care Fluorescence Imaging Device Helps Prevent Graft Rejection Post Modified Radical Mastectomy.

Pathogenic bacteria in wounds impede successful skin grafting. However, their detection relies on culture methods, which delay confirmation by several days. Real-time fluorescence imaging detects bacteria, allowing for rapid assessment and documentation. We herein report a post modified radical mastectomy, surgical site infection with multidrug-resistant Pseudomonas spp. that underwent repeated antibiotic therapy and debridement and eventually grafting. In this case, a real-time fluorescence imaging device helped prevent graft rejection.

BD SurePath Direct to Slide (DTS) cervical cytology: Migrating the benefits of liquid-based cytology to low-resource settings.

OBJECTIVES: The benefits of liquid-based cytology (LBC) in routine cervical cancer screening are often associated with the availability of instrumented platforms and economic considerations. A low-cost alternative to LBC in low-volume settings remains an unmet need. METHODS: A multisite evaluation of the BD SurePath (SurePath) LBC Direct to Slide (DTS) method was conducted. The DTS preparations were evaluated across 3 sites. Cytology features for DTS preparation included predetermined thresholds for total cellularity, cell distribution, cellular preservation, and stain quality. Rare event detection was evaluated using SiHa cells spiked into pools from negative cytology specimens. Concordance between Bethesda classification results was evaluated for SurePath LBC and DTS methods using routinely collected SurePath specimens in a split-sample study design. RESULTS: The DTS specimens met criteria for total cellularity, cell distribution, cellular preservation, and stain quality in more than 98% of all cases. Rare event detection was observed with an average detection of 5 SiHa cells per 2 mL of specimen. Concordant cervical cytology classifications were observed between SurePath LBC and DTS methods. CONCLUSIONS: The results demonstrate that the DTS process is suitable for routine cervical cytology evaluation. The procedure is reproducible and detected abnormal cervical cells in concordance with standard SurePath LBC preparation.

Peri-device leakage and delayed endothelialization of the Watchman device: a computed tomography study.

OBJECTIVES: This study aimed to explore the endothelialization process and assess the potential association between endothelialization and peri-device leak (PDL) following Watchman implantation via a quantitative method. METHODS: This is a single-center retrospective study of consecutive patients undergoing LAAO between December 2015 and November 2021. Device endothelialization, compared between PDL and non-PDL group, were quantitatively analyzed based on hypoattenuated thickening in cardiac computed tomography angiography (CCTA). Advancement in endothelialization over time were explored using the Cochran-Armitage test and generalized estimating equation approach. Potential risk factors of delayed endothelialization were analyzed using the Cox proportional-hazards model. RESULTS: A total of 172 patients (mean age, 68 years ± 10 [standard deviation], 114 men) were finally included. The average endothelialization ratio of the study population was 89.8 ± 7.2 percent. In the follow-up period of postprocedural 3 months to more than 12 months, an incremental trend of endothelialization over time was observed with the ratio of 85.8 ± 8.0, 89.6 ± 7.6, 92.2 ± 4.5, 94.3 ± 2.9 percent, respectively (p < 0.0001). Notably, patients without PDL exhibited a swifter advancement in endothelialization compared to those with PDL, irrespective of device size. The multivariable Cox regression model showed that PDL (HR = 2.113, 95%CI: 1.300-3.435, p = 0.003), DSP (HR = 1.717, 95%CI: 1.113-2.647, p = 0.014) were independent risk factors of delayed endothelialization. CONCLUSION: CCTA holds promise as an effective means of quantitatively assessing device endothelialization. Endothelialization advanced gradually over time, with PDL potentially impeding device endothelialization. CLINICAL RELEVANCE STATEMENT: A comprehensive understanding of the correlation between endothelialization ratio, time, and residual shunt can establish a more dependable foundation for determining the appropriate anticoagulation treatment following left atrial appendage closure. KEY POINTS: Current recommendations for postleft atrial appendage occlusion anti-platelet and anticoagulation therapy are based on animal studies. Cardiac computed tomography angiography (CCTA) combined with the UNet neural network model enables the quantitative assessment of device endothelialization. This technique will allow for additional studies to better understand device endothelialization to optimize treatments in this population.

Assessment of a New Medical Device (PirifixTM) for Positioning and Maintaining the Upper Dental Arch during Le Fort I Osteotomy.

INTRODUCTION: Several medical devices (MDs) are used to assist surgeons in positioning the upper dental arch (UDA) during Le Fort I osteotomies (LFIOs). Some only allow holding, others only positioning. This study aimed to assess the accuracy of a new MD (PirifixTM) coupling these two functions during LFIO on 3D-printed models. MATERIALS AND METHODS: DICOM data were selected from patients who underwent surgical planning for LFIO between 27 July 2020 and 1 December 2022. Their anatomy was reproduced after segmentation, planning, and stereolithography in two models. Each model was assigned to one of two surgical groups: the control group (positioning by occlusal splint) and the PirifixTM group. Each patient's model was planned with the objective of horizontalizing and recentering the UDA. After positioning, models were digitalized using Einscan Pro 2X and compared to the planned model with CloudCompare. The statistical analysis was performed using the Wilcoxon Mann-Whitney test. The result was considered significant if the p-value was less than 0.05. RESULTS: Twenty-one patients were selected. Forty-two anatomical models were 3D-printed. The mean difference compared to the planned and corrected positions was 0.69 mm for the control group and 0.84 mm for the PirifixTM group (p = 0.036). CONCLUSION: PirifixTM may be a new alternative to available MDs. Further investigations are needed to describe the relationship between the device and facial soft tissues.

Drone a technological leap in health care delivery in distant and remote inaccessible areas: A narrative review.

In developing countries, last-mile delivery of medical products is a challenge, especially in hilly and rural areas where there is no road connectivity. As helicopters or other air services are not affordable all the time, drones can be used for the supply of medical products. They are cost-effective as compared to other air or road transport. However, the carrying capacity of drone is less, it is not able to carry heavier payloads. Also, operating drones requires trained operators, and it is a new venture in a developing country so possibilities of confusion and lack of clarity on operating procedures are there. Drones are becoming increasingly reliable for the health care delivery. This narrative review explores the use of drones in healthcare delivery globally.

Ejecución presupuestal y disponibilidad de suministros médicos en establecimientos del nivel III de Lima Metropolitana / Budget execution of SIS financial transfers and availability of medical supplies in MINSA level III establishments in Lima

ABSTRACT Objective: Determine the relationship between the budget execution of financial transfers from the SIS (Seguro Integral de Salud) and the availability of medical supplies in third-level establishments of the Ministry of Health of Metropolitan Lima. Material and method: Analytical and cross-sectional study, carried out in the 20 level III establishments of the MINSA in Lima; Likewise, documentary information was used such as Closing Minutes of Financial Supervision of the Macroregional Management of the SIS from which information on budget execution was obtained and the availability of medical supplies was obtained from the Mundo IPRESS web portal (Institutions Providing Health Services). After evaluating normality with the Shapiro-Wilk test, the Spearman correlation test was used. Result: Overall budget execution was not related to the availability of medical supplies (rho=-0.014; p=0.955). The evaluation by components showed that budget execution on medicines was positively related to the availability of supplies (rho=0.417; p=0.045), which was also valid in the segmented analysis only for hospitals (rho: 0.594; p=0.032). Although budget execution in segmented materials and supplies for hospitals was related to the availability of supplies, this relationship was inverse (rho=-0.552; p=0.043). Conclusions: The general budget execution of financial transfers from the SIS was not related to the availability of medical supplies, but the spending component on medicines was.

Effects of device-performed and manual hip traction and vibration therapy in older adults with symptomatic hip osteoarthritis: A randomized single-blind controlled trial.

BACKGROUND: Traction-and-vibration-therapy (TVT) relieves pain in participants with hip osteoarthritis. Hip TVT is usually performed manually by the physiotherapist. OBJECTIVE: A medical device was developed to perform hip-TVT in order to investigate effects on hip disability, pain intensity, recovery of balance and functional mobility in older adults with hip osteoarthritis and also to reduce physiotherapists' workload and help standardize treatment of hip TVT. METHODS: In a block-randomized 3-month controlled trial involving 28 older adult participants with symptomatic primary hip osteoarthritis (SPHOA), one group (n= 10) received device-performed TVT, one (n= 10) manual TVT, and one (n= 8) sham/placebo therapy. Hip disability (Harris Hip Score), pain intensity (visual-analog-scale), recovery of balance and gait (Functional Gait Assessment) and functional mobility (Timed-Up-and-Go-test) were assessed at baseline, after 3 weeks without intervention, and after 3-month intervention. RESULTS: The Device TVT and Manual TVT groups exhibited superior outcomes compared to the Placebo group in terms of hip disability (p= 0.005 and p< 0.001, respectively), pain intensity (p= 0.002 and p< 0.001, respectively), and functional mobility (TUG) (p= 0.012 and p= 0.011, respectively). Furthermore, the recovery of balance and gait (FGA) showed a significant improvement in the Device TVT group when compared to the Placebo group (p= 0.043). The effect sizes ranged from 0.17 to 0.51, indicating moderate to large effects. CONCLUSION: Device-performed-TVT is comparable to manual hip-TVT for reducing pain and improving mobility in older adults with SPHOA, and may be beneficial in terms of reducing physiotherapists' workload and better therapy standardization.

Device-assisted intravesical chemotherapy versus bacillus Calmette-Guerin for intermediate or high-risk non-muscle invasive bladder cancer: a systematic reviewer and meta-analysis.

PURPOSE: To investigate the effectiveness and safety of device-assisted intravesical chemotherapy compared to Bacillus Calmette-Guerin (BCG) in the treatment of patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS: In February 2023, a systematic search was conducted on the PubMed, Cochrane, and Embase databases. Following the PRISMA guidelines, a systematic review and meta-analysis of the primary outcomes of interest were performed. The review was prospectively registered on PROSPERO under the registration number CRD42023398559. RESULTS: A total of 10 studies involving 1160 patients were included. The results of the meta-analysis showed that compared to BCG, device-assisted chemotherapy had a lower recurrence rate (OR: 0.63, 95% CI: 0.48-0.84, p = 0.001), longer recurrence-free survival (OR: 0.64, 95% CI: 0.47-0.88, p = 0.006), and lower incidence of fever (OR: 0.18, 95% CI: 0.08-0.44, p = 0.0002). However, no significant differences were observed between the two groups in terms of progression, overall survival, progression-free survival, disease-free survival, overall adverse events, serious adverse events, hematuria, allergy, and general discomfort. Subgroup analysis revealed that neither chemohyperthermia (CHT) nor electromotive drug administration (EMDA) showed statistically significant differences in oncological outcomes compared to BCG. Regarding adverse events, both CHT and EMDA groups showed lower rates of fever compared to the BCG group (OR: 0.26, 95% CI: 0.10-0.67, p = 0.005, and OR: 0.14, 95% CI: 0.05-0.37, p < 0.0001, respectively). No significant differences were observed in the remaining adverse events between either the CHT or EMDA group and the BCG group. CONCLUSION: Device-assisted intravesical chemotherapy appears to be a safe and viable alternative to BCG for patients with intermediate and high-risk NMIBC, showing comparable oncological outcomes and adverse events.

Effectiveness of temperature-controlled radiofrequency neurolysis of the posterior nasal nerve to treat chronic rhinitis: a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis evaluates the effect of TRNP on rhinitis-related symptoms. METHODS: We reviewed studies retrieved from PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database to June 2023. Studies that evaluated quality-of-life and rhinitis-related symptom scores before and after treatment were analyzed, as was one sham-treatment-controlled study. RESULTS: In total, 406 patients evaluated in five studies were analyzed. TRNP significantly improved rhinitis-related symptoms-congestion, itching, rhinorrhea, and sneezing-for up to 12 months after treatment, compared to before treatment. The most significant symptom decreases were those of rhinorrhea and nasal congestion. Rhinitis-related symptoms had improved significantly at 3 months after TRNP, compared to sham surgery. TRNP improved disease-specific quality-of-life scores on the Rhinoconjunctivitis Quality of Life Questionnaire at 6 months after treatment, compared to before treatment. The rates of clinical improvement in terms of all nasal symptoms (reduction > 30% from baseline) and in quality of life (minimal clinically important difference > 0.4) after TRNP were 79% and 84% respectively. There was no severe adverse event associated with either device use or the overall procedure. CONCLUSIONS: TRNP treatment improved subjective symptoms related to rhinitis, especially rhinorrhea and nasal congestion, and also improved disease-specific quality-of-life scores.

French community grid for the evaluation of radiological artificial intelligence solutions (DRIM France Artificial Intelligence Initiative).

PURPOSE: The purpose of this study was to validate a national descriptive and analytical grid for artificial intelligence (AI) solutions in radiology. MATERIALS AND METHODS: The RAND-UCLA Appropriateness Method was chosen by expert radiologists from the DRIM France IA group for this statement paper. The study, initiated by the radiology community, involved seven steps including literature review, template development, panel selection, pre-panel meeting survey, data extraction and analysis, second and final panel meeting, and data reporting. RESULTS: The panel consisted of seven software vendors, three for bone fracture detection using conventional radiology and four for breast cancer detection using mammography. A consensus was reached on various aspects, including general target, main objective, certification marking, integration, expression of results, forensic aspects and cybersecurity, performance and scientific validation, description of the company and economic details, possible usage scenarios in the clinical workflow, database, specific objectives and targets of the AI tool. CONCLUSION: The study validates a descriptive and analytical grid for radiological AI solutions consisting of ten items, using breast cancer and bone fracture as an experimental guide. This grid would assist radiologists in selecting relevant and validated AI solutions. Further developments of the grid are needed to include other organs and tasks.

Potential versatile uses of a novel ultra-thin peroral cholangioscope.

Tonozuka and colleagues report the usefulness of a newly developed ultra-thin mother-baby type peroral cholangioscope with a tip external diameter of 2.3 mm for a case of biliary stricture in which conventional peroral cholangioscope insertion was challenging. The novel scope allows simple and low-cost peroral cholangioscopy, making it highly versatile.

Incidence, characteristics, and associated factors of pressure injuries acquired in intensive care units over a 12-month period: A secondary analysis of a quality improvement project.

OBJECTIVES: To determine the 12-month cumulative incidence, characteristics, and associated factors of pressure injuries acquired in Intensive Care Units. SETTING: Four intensive care units in a Norwegian University Hospital. RESEARCH METHODOLOGY: A prospective observational cohort study using data from daily skin inspections during a quality improvement project. We used descriptive statistics and logistic regression. Variables associated with the development of intensive care unit-acquired pressure injuries are presented with odds ratios (OR), and 95% confidence intervals. RESULTS: The 12-month cumulative incidence of patients (N = 594) developing intensive care unit-acquired pressure injuries was 29 % (172/594) for all categories and 16 % (95/594) when excluding category I pressure injuries (no skin loss). Cumulative incidence for patients acquiring medical device-related pressure injuries was 15 % (91/594) and 11 % (64/594) for category II or worse. Compression stockings (n = 51) and nasogastric tubes (n = 22) were the most frequent documented medical devices related to pressure injuries. Development of pressure injuries category II or worse was significantly associated with vasoactive drug infusions (OR 11.84, 95 % CI [1.59; 88.13]) and longer intensive care unit length of stay (OR 1.06, 95 % CI [1.04; 1.08]). CONCLUSION: The 12-month cumulative incidence of intensive care unit-acquired pressure injuries was relatively high when category I pressure injuries were included, but comparable to other studies when category I was excluded. Some medical device-related pressure injuries were surprisingly frequent, and these may be prevented. However, associated factors of developing pressure injuries were present and deemed non-modifiable. IMPLICATIONS FOR CLINICAL PRACTICE: Awareness about pressure injury prevention is needed in the intensive care unit considering high incidences. Nurses can detect category I pressure injuries early, which may be reversed. Our findings show several factors that clinicians can control to reduce the risk of pressure injuries in the intensive care unit.
