RESUMEN

PURPOSE: Minimizing delays in delivering nursing care is paramount for enhancing the overall quality of care. Certain bottleneck variables restrict the workflow of nurses, resulting in extended shift times. This study is designed to pinpoint and analyze the principal factors contributing to bottleneck issues in nursing workflow, to direct improvement endeavors. This study seeks to provide insights into the key variables contributing to nurses' extended shift times, with the ultimate goal of prioritizing efforts for improvement. METHODS: A descriptive multicenter cross-sectional study was conducted. A scale was developed for this study by the authors after conducting a literature review, subsequently validated, and its reliability was assessed. RESULTS: Among the 31 bottleneck variables, 29 were retained under three persistent bottleneck factors: (1) Nurse staffing- This pertains to the availability of sufficient nursing staff at all times across the continuum of care; (2) Working environment and quality of care-This refers to the availability of necessary skills and resources for nurses to perform their duties effectively and; (3) Medical devices- This factor concerns the availability of fully functional medical devices required for providing care. CONCLUSION: Efforts aimed at enhancing the overall healthcare system should concentrate on addressing persistent bottleneck factors. This may involve the implementation of a healthcare workforce management system, the establishment of standards for a conducive and supportive working environment, and the utilization of a standardized system for the management of medical equipment. The outcomes of this study can be utilized by nurses and policymakers to devise comprehensive strategies for improvement.

RESUMEN

PURPOSE: Multiple Sclerosis (MS) is a common autoimmune disease of the central nervous system. MRI plays a crucial role in diagnosing as well as in disease and treatment monitoring. Therefore, evaluation of cerebral MRI of MS patients is part of daily clinical routine. A growing number of companies offer commercial software to support the reporting with automated lesion detection. Aim of this study was to evaluate the effect of such a software with AI supported lesion detection to the radiologic reporting. METHOD: Four radiologist each counted MS-lesions in MRI examinations of 50 patients separated by the locations periventricular, cortical/juxtacortical, infrantentorial and unspecific white matter. After at least six weeks they repeated the evaluation, this time using the AI based software mdbrain for lesion detection. In both settings the required time was documented. Further the radiologists evaluated follow-up MRI of 50 MS-patients concerning new and enlarging lesions in the same manner. RESULTS: To determine the lesion-load the average reporting time decreased from 286.85 sec to 196.34 sec (p > 0.001). For the evaluation of the follow-up images the reporting time dropped from 196.17 sec to 120.87 sec (p < 0.001). The interrater reliabilities showed no significant differences for the determination of lesion-load (0.83 without vs. 0.8 with software support) and for the detection of new/enlarged lesions (0.92 without vs. 0.82 with software support). CONCLUSION: For the evaluation of MR images of MS patients, an AI-based support for image-interpretation can significantly decreases reporting times.

RESUMEN

Wet granulation, a particle size enlargement process, can significantly enhance the critical quality attributes of powders and improve the ability to form tablets in pharmaceutical manufacturing. In this study, a mechanistic-based population balance model is applied to twin screw wet granulation. This model incorporated a recently developed breakage kernel specifically designed for twin screw granulation, along with nucleation, layering, and consolidation. Calibration and validation were performed on Hydrochlorothiazide and Acetaminophen formulations, which exhibit different particle size and wettability characteristics. Utilizing a compartmental experimental dataset, a comprehensive global sensitivity analysis identified critical inputs impacting quality attributes. The study revealed that the nucleation rate process model, effectively represented particle size distributions for both formulations. Adjustments to nucleation and breakage rate parameters, influenced by material properties and screw configuration, improved the model's accuracy. A model-driven workflow was proposed, offering step-by-step guidelines and facilitating PBM model usage, providing essential details for future active pharmaceutical ingredient (API) formulations.

RESUMEN

In-depth transcriptomic and proteomic analyses are crucial for understanding normal and pathological biology. Next-generation sequencing technology (NGS) is used to assess gene expression, but protein abundance cannot be scaled up due to the lack of methods like PCR. This presents a major obstacle to proteomics at the single-cell level, as protein expression dictates cell state. Biochemists are interested in single-cell analysis of proteins, as analyzing tissues with diverse cell types hides cell-to-cell differences, making it difficult to interpret the resulting data. Single-cell proteomics is a promising field that provides direct yet comprehensive molecular insights into cellular functions without averaging effects. However, protein adsorption loss (PAL) has been a technical challenge, and mitigations have been generic, with efficacy evaluated by the size of the resolved proteome without specificity on individual proteins. Advances in sample processing, separations, and mass spectrometry have made it possible to quantify >1000 proteins from individual mammalian cells, a level of coverage that required thousands of cells just a few years ago.

RESUMEN

BACKGROUND: After coronavirus disease outbreak emerged in 2019, radiotherapy departments had to adapt quickly their health system and establish new organizations and priorities. The purpose of this work is to report our experience in dealing with COVID-19 emergency, how we have reorganized our clinical activity, changed our priorities, and stressed the use of hypofractionation in the treatment of oncological diseases. MATERIALS AND METHODS: The patients' circuit of first medical examinations and follow-up was reorganized; a more extensive use of hypofractionated schedules was applied; a daily triage of the patients and staff, use of personal protective equipment, hand washing, environment sanitization, social distancing and limitations for the patients' caregivers in the department, unless absolutely essential, were performed; patients with suspected or confirmed COVID-19 were treated at the end of the day. In addition, the total number of radiotherapy treatment courses, patients and sessions, in the period from February 15 to April 30, 2020, comparing the same time period in 2018 were retrospectively investigated. In particular, changes in hypofractionated schedules adopted for the treatment of breast and prostate cancer and palliative bone metastasis were analyzed. RESULTS: Between February 15, and April 30, 2020, an increased number of treatments was carried out: Patients treated were overall 299 compared to 284 of the same period of 2018. Stressing the use of hypofractionation, 2036 RT sessions were performed, with a mean number of fractions per course of 6.8, compared to 3566 and 12.6, respectively, in 2018. For breast cancer, the schedule in 18 fractions has been abandoned and treatment course of 13 fractions has been introduced; a 27% reduction in the use of 40.5 Gy in 15 fractions, (67 treatments in 2018-49 in 2020) was reported. An increase of 13% of stereotactic body radiation therapy for prostate cancer was showed. The use of the 20 Gy in 4 or 5 sessions for the treatment of symptomatic bone metastasis decreased of 17.5% in favor of 8 Gy-single fraction. Three patients results COVID-19 positive swab: 1 during, 2 after treatment. Only one staff member developed an asymptomatic infection. CONCLUSIONS: The careful application of triage, anti-contagion and protective measures, a more extensive use of hypofractionation allowed us to maintain an effective and continuous RT service with no delayed/deferred treatment as evidenced by the very low number of patients developing COVID-19 infection during or in the short period after radiotherapy. Our experience has shown how the reorganization of the ward priority, the identification of risk factors with the relative containment measures can guarantee the care of oncological patients, who are potentially at greater risk of contracting the infection.

RESUMEN

BACKGROUND: Over the past 20 years, there have been many innovations in orthodontic diagnosis and therapy. Among the innovations, there is the taking of dental impressions (DIs). Dental impressions are the negative imprint of hard and soft tissues of one or both arches, and they allow a plaster model to be formed, i.e., a positive reproduction. Traditional dental impressions can be made of different materials, such as alginate, while digital impression is captured by an intra-oral scanner. Digital impression, despite the evident advantages, has not yet replaced the conventional impression. The aim of this study is to evaluate which dental impressions are the most used by dentists. For this purpose, we considered 120 questionnaires sent electronically to patients of different dental private practices from different countries, where the dentists can use both techniques. The results highlighted that the kind of impression adopted is very much influenced by the type of therapy and orthodontic devices used in the treatment. We can conclude that, despite the advent of digital technology, conventional impressions are still used for fixed devices, while digital impressions are more adopted for orthodontic customized devices and therapies with clear aligners, that are very widespread among adult patients.

RESUMEN

OBJECTIVE: The conventional anterior esthetic treatment protocol is limited as it's time consuming and unreliable. A predictable digital workflow for minimally invasive anterior esthetic tooth rehabilitation with global diagnosis principle has been introduced in this report. CLINICAL CONSIDERATIONS: A 23-year-old female patient with the chief complaint of unsatisfied shape and color of her anterior teeth visited our hospital for restorative consultation. Three-dimensional Digital Smile Design was used to integrate into a virtual patient model to provide rehabilitative esthetic planning with global diagnostic principle. 3D printer was used for communication and guidance preparation. Digital impression and computer-aided design/computer-aided manufacturing technologies were adopted for making the morphology of designed restorations that can precisely transfer to definitive prostheses. The esthetics, functional occlusion, and gingival tissues remained stable for over a follow-up period of 3 years. No signs of fractures within the restorations were observed. CONCLUSIONS: Minimally invasive anterior esthetic tooth rehabilitation can be readily achieved using a predictable digital workflow with global diagnosis principle. CLINICAL SIGNIFICANCE: This digital approach might promote diagnosis, enhance communication, reduce processing time, and increase the predictability of final outcomes with high comfort and esthetic effect.

RESUMEN

Telehealth in intensive care units (TeleICU) is the provision of critical care using audio-visual communication and health information systems across varying clinical and geographically dispersed settings. The optimal structure of a TeleICU team is one that leverages expert clinical knowledge to address the needs of critical care patients, regardless of hospital location or availability of an onsite intensivist. Information related to the optimal TeleICU team structure is lacking. This article examines the optimal TeleICU team composition, which is one that incorporates the use of an interdisciplinary approach, leverages technology, and is cognizant of varying geographic locations.

RESUMEN

Background and Purpose: Pre- and intra-hospital workflow in mechanical recanalization of large cervicocephalic arteries in patients with acute ischemic stroke still needs optimization. In this study, we analyze workflow and outcome in our routine care of stroke patients undergoing mechanical thrombectomy as a precondition for such optimization. Methods: Processes of pre- and intra-hospital management, causes of treatment delay, imaging results (Alberta Stroke Program Early Computed Tomography Score, localization of vessel occlusion), recanalization (modified thrombolysis in cerebral infarction score), and patient outcome (modified Rankin scale at discharge and at the end of inpatient rehabilitation) were analyzed for all patients who underwent mechanical thrombectomy between April 1, 2016, and September 30, 2018, at our site. Results: Finally, data of 282 patients were considered, of whom 150 (53%) had been referred from external hospitals. Recanalization success and patient outcome were similar to randomized controlled thrombectomy studies and registries. Delay in treatment occurred when medical treatment of a hypertensive crisis, epileptic fits, vomiting, or agitation was mandatory but also due to missing prenotification of the hospital emergency staff by the rescue service, multiple mode or repeated brain imaging, and transfer from another hospital. Even transfer from external hospitals located within a 10-km radius of our endovascular treatment center led to a median increase of the onset-to-groin time of ~60 min. Conclusion: The analysis revealed several starting points for an improvement in the workflow of thrombectomy in our center. Analyses of workflow and treatment results should be carried out regularly to identify the potential for optimization of operational procedures and selection criteria for patients who could benefit from endovascular treatment.

RESUMEN

BACKGROUND: In many countries, the worldwide spread of COVID-19 has led to a near total stop of non-urgent, elective surgeries across all specialties during the first wave's peak of the pandemic. For providers of aesthetic surgery procedures or minimal invasive cosmetic treatments, this led to a huge socio-economic impact worldwide. In order to evaluate valid clinical management strategies for future pandemic events and to overcome the challenges imposed by the current pandemic, it is paramount to analyse the socio-economic effects caused by the COVID-19 crisis. METHODS: An online survey comprising 18 questions was sent out five times by e-mail to all members of the International Society of Aesthetic Plastic Surgery (ISAPS) between June and August 2020. The data set was statistically analyzed and grouped into an overall group and into subgroups of countries with high (n = 251) vs. low (n = 440) gross domestic product per capita (GDP p.c.) and five defined world regions (Europe (n = 214); North America (NA; n = 97); South America (SA; n = 206); Asia and Oceania (Asia + OC; n = 99); Africa and Middle East (Africa + ME; n = 75)). RESULTS: A total of 691 recipients completed the survey. The majority of the participants experienced severe operating restrictions resulting in a major drop of income from surgical patients. Low GDP p.c. countries experienced a bigger negative economic impact with less aesthetic (non-) surgical procedures, whereas the high GDP p.c. subgroup was less affected by the COVID-19 crisis. Most of the survey participants had already adopted the ISAPS guidelines for patient (pre-) appointment screening and clinical/patient-flow management. For surgical and non-surgical aesthetic procedures, in the high GDP p.c. subgroup more basic-level PPE (surgical mask) was used, whereas the low GDP p.c. subgroup relied more on advanced-level PPE (N-95 respirator mask or higher). Comparing the different world regions, Europe and Africa used more basic-level PPE. CONCLUSIONS: Measurable differences in the socio-economic impact and in the adaptation of safety protocols between high and low GDP p.c. subgroups and between different world regions were present. Since the COVID-19 pandemic is an international crisis, aligned, expedient and universal actions should be taken.

RESUMEN

INTRODUCTION: Pragmatic trials in comparative effectiveness research assess the effects of different treatment, therapeutic, or healthcare options in clinical practice. They are characterized by broad eligibility criteria and large sample sizes, which can lead to an unmanageable number of participants, increasing the risk of bias and affecting the integrity of the trial. We describe the development of a sampling strategy tool and its use in the PREPARE trial to circumvent the challenge of unmanageable work flow. METHODS: Given the broad eligibility criteria and high fracture volume at participating clinical sites in the PREPARE trial, a pragmatic sampling strategy was needed. Using data from PREPARE, descriptive statistics were used to describe the use of the sampling strategy across clinical sites. A Chi-square test was performed to explore whether use of the sampling strategy was associated with a reduction in the number of missed eligible patients. RESULTS: 7 of 20 clinical sites (35%) elected to adopt a sampling strategy. There were 1539 patients excluded due to the use of the sampling strategy, which represents 30% of all excluded patients and 20% of all patients screened for participation. Use of the sampling strategy was associated with lower odds of missed eligible patients (297/4545 (6.5%) versus 341/3200 (10.7%) p < 0.001). CONCLUSIONS: Implementing a sampling strategy in the PREPARE trial has helped to limit the number of missed eligible patients. This sampling strategy represents a simple, easy to use tool for managing work flow at clinical sites and maintaining the integrity of a large trial.

RESUMEN

Background: The clinical benefit from endovascular therapy (EVT) for patients with acute ischemic stroke is time-dependent. We tested the hypothesis that team prenotification results in faster procedure times prior to initiation of EVT. Methods: We analyzed data from our prospective database (01/2016-02/2018) including all patients with acute ischemic stroke who were evaluated for EVT at our comprehensive stroke center. We established a standardized algorithm (EVT-Call) in 06/2017 to prenotify team members (interventional neuroradiologist, neurologist, anesthesiologist, CT and angiography technicians) about patient transfer from remote hospitals for evaluation of EVT, and team members were present in the emergency department at the expected patient arrival time. We calculated door-to-image, image-to-groin and door-to-groin times for patients who were transferred to our center for evaluation of EVT, and analyzed changes before (-EVT-Call) and after (+EVT-Call) implementation of the EVT-Call. Results: Among 494 patients in our database, 328 patients were transferred from remote hospitals for evaluation of EVT (208 -EVT-Call and 120 +EVT-Call, median [IQR] age 75 years [65-81], NIHSS score 17 [12-22], 49.1% female). Of these, 177 patients (54%) underwent EVT after repeated imaging at our center (111/208 [53%) -EVT-Call, 66/120 [55%] +EVT-Call). Median (IQR) door-to-image time (18 min [14-22] vs. 10 min [7-13]; p < 0.001), image-to-groin time (54 min [43.5-69.25] vs. 47 min [38.3-58.75]; p = 0.042) and door-to-groin time (74 min [58-86.5] vs. 60 min [49.3-71]; p < 0.001) were reduced after implementation of the EVT-Call. Conclusions: Team prenotification results in faster patient assessment and initiation of EVT in patients with acute ischemic stroke. Its impact on functional outcome needs to be determined.

RESUMEN

Measurement-based care (MBC) is recognized as a valuable component to maximize quality in psychiatric care; however, actual use of MBC by practitioners is poor. A host of implementation barriers have been noted, and are likely significant contributors to this poor adoption. Many of these barriers are related to work-flow issues that can be managed or mitigated by appropriate infrastructure considerations. This article offers an overview of the continuum of infrastructures to support MBC in clinical practice, delineating the tradeoffs between these infrastructures, and then identifying specific experience-based strategies for addressing several major patient-, provider-, and organization-level barriers to MBC implementation.

RESUMEN

INTRODUCTION: Intra-operative stroke (IOS) is associated with poor clinical outcome as detection is often delayed and time of symptom onset or patient's last known well (LKW) is uncertain. Intra-operative neurophysiological monitoring (IONM) is uniquely capable of detecting onset of neurological dysfunction in anesthetized patients, thereby precisely defining time last electrically well (LEW). This novel parameter may aid in the detection of large vessel occlusion (LVO) and prompt treatment with endovascular thrombectomy (EVT). METHODS: We performed a retrospective analysis of a prospectively maintained AIS and LVO database from May 2018-August 2019. Inclusion criteria required any surgical procedure under general anesthesia (GA) utilizing EEG (electroencephalography) and/or SSEP (somatosensory evoked potentials) monitoring with development of intraoperative focal persistent changes using predefined alarm criteria and who were considered for EVT. RESULT: Five cases were identified. LKW to closure time ranged from 66 to 321 minutes, while LEW to closure time ranged from 43 to 174 min. All LVOs were in the anterior circulation. Angiography was not pursued in two cases due to large established infarct (both patients expired in the hospital). EVT was pursued in two cases with successful recanalization and spontaneous recanalization was noted in one patient (mRS 0-3 at 90 days was achieved in all 3 cases). CONCLUSIONS: This study demonstrates that significant IONM changes can accurately identify patients with an acute LVO in the operative setting. Given the challenges of recognizing peri-operative stroke, LEW may be an appropriate surrogate to quickly identify and treat IOS.

RESUMEN

Completely digital workflows for the fabrication of implant-supported removable restorations are not yet common in clinical dental practice. The aim of the current case report is to illustrate a reliable and comfortable workflow that reasonably merges conventional and digital workflows for the CAD/CAM-fabrication of implant-supported overdentures. The 53-year old patient was supplied with a digitally processed complete denture in the upper jaw and, simultaneously, with an overdenture supported by four interforaminal implants in the lower jaw. The overdenture included a completely digitally processed and manufactured alloy framework that had been fabricated by selective laser sintering. The case report indicates that digital manufacturing processes for extensive and complex removable restorations are possible. However, as it is currently not yet possible to digitally obtain functional impressions, future developments and innovations might focus on that issue.

RESUMEN

PURPOSE: Hospital occupancy (HospOcc) pressures often lead to longer intensive care unit (ICU) stay after physician recognition of discharge readiness. We evaluated the relationships between HospOcc, extended ICU stay, and patient outcomes. MATERIALS AND METHODS: 7-year retrospective cohort study of 8500 alive discharge encounters from 4 adult ICUs of a tertiary hospital. We estimated associations between i) HospOcc and ICU transfer delay; and ii) ICU transfer delay and hospital mortality. RESULTS: Median (IQR) ICU transfer delay was 4.8 h (1.6-11.7), 1.4% (119) suffered in-hospital death, and 4% (341) were readmitted. HospOcc was non-linearly related with ICU transfer delay, with a spline knot at 80% (mean transfer delay 8.8 h [95% CI: 8.24, 9.38]). Higher HospOcc level above 80% was associated with longer transfer delays, (mean increase 5.4% per % HospOcc increase; 95% CI, 4.7 to 6.1; P < .001). Longer ICU transfer delay was associated with increasing odds of in-hospital death or ICU readmission (odds ratio 1.01 per hour; 95% CI 1.00 to 1.01; P = .04) but not with ICU readmission alone (OR 1.01 per hour; 95% CI 1.00 to 1.01, P = .14). CONCLUSIONS: ICU transfer delay exponentially increased above a threshold hospital occupancy and may be associated with increased hospital mortality.

RESUMEN

AIMS: Faecal microbiota transplantation (FMT) consists of the infusion of faeces from a healthy donor to the gastrointestinal tract of a recipient patient to treat disease associated with alterations in gut microbiota. The objective of this article was to describe laboratory workflow of an FMT laboratory to provide tips for preparing the faecal suspensions to be infused. METHODS AND RESULTS: Twenty-stool solutions obtained from ten donors were prepared using two different protocols: magnet plate emulsion (MPE) and Seward StomacherTM Emulsion (SSE). We evaluated parameters such as preparation time, handiness, and aerobic and anaerobic microbial count. For three donors, we monitored bacterial counts after defrosting at different time-points. MPE requires more time than SSE. In terms of microbial load, both methods showed similar values, with small and statistically differences (P ≤ 0·05) regarding anaerobes in favour of SSE. Frozen aliquots showed the same bacterial load values after defrosting. CONCLUSION: Although both methods allow an easy and available preparation of a stool suspension, SSE seems more suitable, particularly for stool banking. Aerobic and anaerobic species are preserved with both protocols; and safety for laboratory operators is guaranteed. SIGNIFICANCE AND IMPACT OF THE STUDY: In recent years, FMT has become a fascinating and interesting subject. Nevertheless, there are no real guidelines describing laboratory facilities and procedures. This paper aims to be a useful and simple guide to increase the number FMT centres as much possible.

RESUMEN

High-density lipoproteins (HDLs) have anti-inflammatory and antioxidant properties and are potentially cardio-protective. Defective HDL function is caused by alterations in both the proteome and lipidome of HDL particles. As potential biomarkers, the development of analytical methods is necessary for the enrichment of HDLs. Therefore, a method for selective enrichment of HDLs using immobilized metal ion affinity chromatography (IMAC) and metal oxide affinity chromatography (MOAC) is presented. SPE-based isolation of HDLs from whole serum is adopted as an alternative to traditional ultracentrifugation methods followed by SDS-PAGE. The enrichment mechanism relies on isoelectric points of lipoproteins and metal oxide. Negatively charged lipoprotein particles interact with positively charged metal oxides and IMAC affinity, which acts as a cation. Identified proteins from HDL through MALDI-MS analysis are apo AI, AII, AIV, CI, CIII, E, J, M, H, serum amyloid A and other nonapoproteins that are part of HDL particles and perform cellular functions. This serum-based proteomics approach gives insight into the functional role of HDL. HDL-associated phospholipids have also been analyzed by LDI-MS. Results suggest that the adopted analytical strategy is a feasible idea to extract lipoproteins from serum.
