Compensatory recruitment allows amphibian population persistence in anthropogenic habitats.

Habitat anthropization is a major driver of global biodiversity decline. Although most species are negatively affected, some benefit from anthropogenic habitat modifications by showing intriguing life-history responses. For instance, increased recruitment through higher allocation to reproduction or improved performance during early-life stages could compensate for reduced adult survival, corresponding to "compensatory recruitment". To date, evidence of compensatory recruitment in response to habitat modification is restricted to plants, limiting understanding of its importance as a response to global change. We used the yellow-bellied toad (Bombina variegata), an amphibian occupying a broad range of natural and anthropogenic habitats, as a model species to test for and to quantify compensatory recruitment. Using an exceptional capture-recapture dataset composed of 21,714 individuals from 67 populations across Europe, we showed that adult survival was lower, lifespan was shorter, and actuarial senescence was higher in anthropogenic habitats, especially those affected by intense human activities. Increased recruitment in anthropogenic habitats fully offset reductions in adult survival, with the consequence that population growth rate in both habitat types was similar. Our findings indicate that compensatory recruitment allows toad populations to remain viable in human-dominated habitats and might facilitate the persistence of other animal populations in such environments.

Normothermic regional perfusion in controlled DCD liver procurement: Outcomes of the Swedish national implementation protocol.

Liver transplantation using donors after controlled circulatory death (cDCD) is associated with poorer graft survival and increased incidence of non-anastomotic biliary strictures (NAS) compared to livers procured from brain dead donors (DBD). The use of Normothermic regional perfusion (NRP) during cDCD procurement may improve post-transplant outcome and reduce the incidence of NAS. In Sweden cDCD liver transplantation was introduced through a national pilot protocol with mandatory NRP. This study aims to evaluate the outcome of cDCD liver transplantation during the pilot period. Donor and recipient data were collected on all cDCD liver transplants during the pilot period between 2020 - December 2022. Outcome on NAS, patient- and graft survival, early allograft dysfunction, acute kidney injury, and comprehensive complication index was compared to a matched cohort of 28 patients transplanted with a DBD liver between 2018-2022. 18 patients were transplanted with a liver from a cDCD donor after using NRP. Mean functional warm ischemia time was 29±6 minutes. Mean lactate reduction during NRP was 8.7±2.4 mmol/L, end NRP perfusate ALT was 1.4±1 µkat/L. When comparing cDCD liver transplant recipients to DBD, no significant differences were observed in the incidence of NAS, patient and graft survival, comprehensive complication index, early allograft dysfunction, nor acute kidney injury. Study protocol MRCP in cDCD patients showed no signs of subclinical biliary strictures. Evaluation of the Swedish national pilot of cDCD liver transplantation with mandatory NRP shows comparable outcomes to a matched DBD cohort with 94.4 one-year patient and graft survival and no incidence of NAS within the first year.

Cerebellar mutism syndrome caused by bilateral cerebellar hemorrhage in adults: a case report and review of the literature.

Cerebellar mutism syndrome (CMS) is a frequent complication of surgical intervention on posterior fossa in children. It has been only occasionally reported in adults and its features have not been fully characterized. In children and in young adults, medulloblastoma is the main reason for neurosurgery. A single case of postsurgical CMS is presented in an adult patient with a cerebellar hemorrhage and a systematic review of the published individual cases of CMS in adults was done. Literature review of individual cases found 30 patients, 18/30 (60%) males, from 20 to 71 years at diagnosis. All but one case was post-surgical, but in one of the post-surgical cases iatrogenic basilar artery occlusion was proposed as cause for CMS. The causes were: primary tumors of the posterior fossa in 16/22 (72.7%) metastasis in 3/30 (10%), ischemia in 3/30 (10%) cerebellar hemorrhage in 3/30 (10%), and benign lesions in 2/30 (6.7%) patients. 8/30 patients (26.7%) were reported as having persistent or incomplete resolution of CMS within 12 months. CMS is a rare occurrence in adults and spontaneous cerebellar hemorrhage has been reported in 3/30 (10%) adult patients. The generally accepted hypothesis is that CMS results from bilateral damage to the dentate nucleus or the dentate-rubro-thalamic tract, leading to cerebro-cerebellar diaschisis. Several causes might contribute in adults. The prognosis of CMS is slightly worse in adults than in children, but two thirds of cases show a complete resolution within 6 months.

Volumetric graft changes after liver transplantation: evidence of adaptation to recipient body size.

It is believed that whole liver grafts adjust their size to fit the body size of the recipient after transplantation, despite a lack of evidence. The aim of this study was to test this hypothesis. This was a retrospective cohort study of 113 liver transplantations performed at Karolinska University Hospital. The cohort was divided based on graft volume-to-standard liver volume ratio (GV/SLV) into quartiles of small, mid, and large grafts. Serial volumetric assessment was performed on the day of transplantation and at posttransplant check-ups early (<2 mo) and late (9-13 mo) after transplantation using computed tomography (CT) volumetry. Change in GV/SLV ratio over time was analyzed with ANOVA repeated measures. A multiple regression model was used to investigate the influence of intraoperative blood flow, recipient body size, age, and relative sickness on graft volume changes. Between the three time points, mean GV/SLV ratio adapted to 0.55-0.94-1.00 in small grafts (n = 29, P < 0.001); 0.87-1.18-1.13 in midgrafts (n = 56, P < 0.001); 1.11-1.51-1.18 in large grafts (n = 28, P < 0.001). Regression analysis showed a positive correlation between posttransplant graft growth and portal flow (ß = 1.18, P = 0.005), arterial flow (ß = 0.17, P = 0.001), and recipient body surface area (ß = 59.85, P < 0.001). A negative correlation was observed for graft weight-to-recipient weight ratio (GRWR; ß = -33.12, P < 0.001). Grafts with initial GV/SLV-ratio < 0.6 adapt toward the ideal volume for recipient body size 1 year after transplantation. The disparity between graft size relative to recipient body size, and the portal and arterial perfusion, influence volumetric graft changes.NEW & NOTEWORTHY This is the first and largest human study to verify the hypothesis that whole liver grafts adjust their size to match recipient body size 1 year after transplantation-a phenomenon that has previously only been observed in experimental animal studies and human case reports. The direction of volumetric changes is driven by the disparity between graft size relative to recipient body surface area and weight, as well as the intraoperative portal- and arterial graft perfusion.

Mirage of Luminal Modified Gravitational-Wave Propagation.

Using conformal invariance of gravitational waves, we show that for a luminal modified gravity theory, the gravitational-wave propagation and luminosity distance are the same as in general relativity. The relation between the gravitational-wave and electromagnetic-wave luminosity distance gets modified, however, for electromagnetism minimally coupled to the Jordan frame metric. Using effective field theory we show that the modified relation obtained for luminal theories is also valid for nonluminal theories with Jordan frame matter-gravity coupling. We generalize our analysis to a time-dependent speed of gravitational waves with matter minimally coupled to either the Jordan or Einstein frame metrics.

Pituitary Abscess: A Challenging Preoperative Diagnosis-A Multicenter Study.

Background and Objectives: Pituitary abscess (PA) is a rare occurrence, representing less than 1% of pituitary lesions, and is defined by the presence of an infected purulent collection within the sella turcica. Pas can be classified as either primary, when the underlying pituitary is normal prior to infection, or secondary, when there is associated a pre-existing sellar pathology (i.e., pituitary adenoma, Rathke's cleft cysts, or craniopharyngioma), with or without a recent history of surgery. Preoperative diagnosis, owing to both non-specific symptoms and imaging features, remains challenging. Treatment options include endonasal trans-sphenoidal pus evacuation, as well as culture and tailored antibiotic therapy. Methods: A retrospective multicenter study, conducted on a prospectively built database over a 20-year period, identified a large series of 84 patients harboring primary sellar abscess. The study aimed to identify crucial clinical and imaging features in order to accelerate appropriate management. Results: The most common clinical presentation was a symptom triad consisting of various degrees of asthenia (75%), visual impairment (71%), and headache (50%). Diagnosis was achieved in 95% of cases peri- or postoperatively. Functional recovery was good for visual disturbances and headache. Pituitary function recovery remained very poor (23%), whereas the preoperative diagnosis represented a protective factor. Conclusions: In light of the high prevalence of pituitary dysfunction following the management of PAs, early diagnosis and treatment might represent a crucial issue. Currently, there are no standard investigations to establish a conclusive preoperative diagnosis; however, new, emerging imaging methods, in particular nuclear imaging modalities, represent a very promising tool, whose potential warrants further investigations.

Efficacy of endoscopic management of primary central nervous system lymphoma: a multicentric study and literature review.

INTRODUCTION: To date, confined intra-ventricular localization of primary central nervous system lymphoma (PCNSL) has been usually managed with open surgical resection and/or stereotactic biopsy; nonetheless, the endoscopic approach to such localization can provide many advantages over standard microsurgery and/or stereotactic biopsy. Here we present our experience in managing such a rare pathology through the endoscopic approach. METHOD: In order to gather more information about such a rare pathology, a retrospective multicentric study on a prospectively built database has been performed during a 5 year period. Ten different European centers have been involved. RESULTS: A total of 60 patients, 25 women and 35 men, have been enrolled in the study. The mean age was 65.3 years. The mean lesion size was 40.3 mm. Among all selected patients, 40 (66.6%) had superficial lesions within the ventricle, whereas the remaining 20 (33.4%) had lesions involving/extending to deeper structures. All surgical procedures were uneventful and ETV was deemed necessary only in 20/60 cases. CONCLUSION: In our experience, endoscopic management of intraventricular PCNSL is an effective option. It should be considered after a careful examination of neurological and immunological status, alternative options for diagnostic sampling, location of the lesion, and presence or absence of hydrocephalus. Endoscopic management could be considered as a safe and minimally invasive option to obtain: (a) a biopsy sample of the lesion for further diagnostic workup, (b) CSF diversion through third ventriculostomy or VP shunt for the management of hydrocephalus, and (c) insertion of ventricular access devices for long term medical management and whenever necessary as a rescue option for ventricular tap.

Odontoid Type II fractures in elderly: what are the real management goals and how to best achieve them? A multicenter European study on functional outcome.

Odontoid fractures constitute the most common cervical fractures in elderly. External immobilization is the treatment of choice for Type I and III; there is still no wide consensus about the best management of Type II fractures. Observational multicenter study was conducted on a prospectively built database on elderly patients (> 75 years) with Type II odontoid fracture managed conservatively during the last 10 years. All patients underwent CT scan on admission and at 3 months; if indicated, selected patient had CT scan at 6 and 12 months. All patients were clinically evaluated by Neck Disability Index (NDI), Charlson Comorbidity Index (CCI), and American Society of Anaesthesiologists classification (ASA) on admission; NDI was assessed also at 6 weeks, 3, 6, 12, and 24 months; furthermore, a quality of life (QoL) assessment with the SF-12 form was performed at 3 and 12 months. Among the 260 patients enrolled, 177 (68%) were women and 83 (32%) men, with a median age of 83 years. Patients were followed up for a minimum of 24 months: 247 (95%) showed an excellent functional outcome within 6 weeks, among them 117 (45%) showed a good bony healing, whereas 130 (50%) healed in pseudo-arthrosis. The residual 5% were still variably symptomatic at 12 weeks; however, only 5 out of 13 (2% of the total cohort) required delayed surgery. This study showed that a conservative approach to odontoid Type II fracture in elderly is an effective and valid option, resulting in an excellent functional outcome (regardless of bony fusion) in the majority of cases. Failure of conservative treatment can be safely addressed with surgical fixation at a later stage.

Endoscopic-enhanced supra-cerebellar trans-tentorial (SCTT) approach to temporo-mesial region: a multicenter study.

Surgical access to the temporo-mesial area may be achieved by several routes such as the sub-temporal, the temporal trans-ventricular, the pterional/trans-sylvian, and the occipital interhemispheric approaches; nonetheless, none of them has shown to be superior to the others. The supra-cerebellar trans-tentorial approach allows a great exposure of the middle and posterior temporo-mesial region, while avoiding temporal lobe retraction. A prospective multicenter study was designed to collect data on patients undergoing endoscopic-enhanced SCTT approach to excise left temporo-mesial lesions. The study involved 5 different neurosurgical European centers and ran from 2015 to 2020. All patients had preoperative as well as postoperative brain MRI and ophthalmology evaluation. A total of 30 patients were included in this study, the mean follow-up was 44 months (range 18 to 84 months), male/female ratio was 16/14, and mean age was 39 years. A gross total resection was achieved in 29/30 (96.7%) cases. All surgical procedures were uneventful, without transient or permanent neurological deficits thanks to the preservation of the posterior cerebral artery. The endoscopic-enhanced SCTT approach provides satisfactory exposure to the left temporo-mesial region. Its minimally invasive nature helps minimize the surgical risks related to vascular and white tract manipulation, which represent known limitations of open microsurgical as well as other approaches.

Primary ectopic orbital craniopharyngioma.

Craniopharyngiomas (CP) ectopic localizations off the midline outside the sellar-suprasellar region are very rare and most often associated to secondary tumor dissemination, being primary ectopic CPs extremely unusual. We herein report the first case of a primary ectopic craniopharyngioma within the orbit. A 15-year-old patient presented with progressive right ptosis, proptosis, and retro ocular pain. Magnetic resonance imaging (MRI) showed a predominantly cystic lesion, occupying the superolateral right corner of the orbit, outside the intraconal space with no evidence of intracranial involvement. An endoscopic transorbital eyelid approach was adopted. Pathology report disclosed a primary ectopic craniopharyngioma.

The clinical impact of direct-acting antiviral treatment on patients affected by hepatitis C virus-related oral lichen planus: a cohort study.

OBJECTIVES: Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous disease. Literature supports an association between OLP and Hepatitis C virus (HCV) infection. The current treatment for HCV infection with direct-acting antivirals (DAAs) is highly effective and safe. The aim of this study is to evaluate the clinical impact of viral eradication with DAAs in patients with HCV and OLP. MATERIALS AND METHODS: For this cohort observational study, 18 patients with HCV and OLP were recruited; all patients received DAAs. Nineteen patients with OLP without HCV were recruited as controls. Both groups received an oral clinical examination, taking photographs of the oral mucosa, at three time points. Size and type of lesions, clinical and efficacy scores, were evaluated at each time point with ImageJ software. Changes were assessed by a general linear model repeated measures analysis. Kruskal-Wallis H and Mann-Whitney U tests were used to evaluate the differences between subgroups. RESULTS: All patients of the study group reached a sustained virological response. The study group showed a correlation between viral load and clinical status (p < 0.05), higher clinical scores at baseline (p = 0.001) and higher efficacy index than controls (p < 0.001), improving over time (p < 0.001); controls did not show significant changes (p = 0.196). One patient of the experimental group developed oral squamous cell carcinoma (OSCC) of the tongue during the DAAs treatment. CONCLUSIONS: In this study, patients with HCV and OLP showed a worst clinical oral status than controls at baseline. However, treatment for virus eradication can improve the oral lichen planus clinical course. CLINICAL RELEVANCE: HCV eradication can improve the clinical course of patients with HCV-related OLP.

PacDOCK: A Web Server for Positional Distance-Based and Interaction-Based Analysis of Docking Results.

Molecular docking is a key method for structure-based drug design used to predict the conformations assumed by small drug-like ligands when bound to their target. However, the evaluation of molecular docking studies can be hampered by the lack of a free and easy to use platform for the complete analysis of results obtained by the principal docking programs. To this aim, we developed PacDOCK, a freely available and user-friendly web server that comprises a collection of tools for positional distance-based and interaction-based analysis of docking results, which can be provided in several file formats. PacDOCK allows a complete analysis of molecular docking results through root mean square deviation (RMSD) calculation, molecular visualization, and cluster analysis of docked poses. The RMSD calculation compares docked structures with a reference structure, also when atoms are randomly labelled, and their conformational and positional differences can be visualised. In addition, it is possible to visualise a ligand into the target binding pocket and investigate the key receptor-ligand interactions. Moreover, PacDOCK enables the clustering of docking results by identifying a restrained number of clusters from many docked poses. We believe that PacDOCK will contribute to facilitating the analysis of docking results to improve the efficiency of computer-aided drug design.

Real-life evidence of low-dose mepolizumab efficacy in EGPA: a case series.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare, small vessel, necrotizing vasculitis. The disease is mainly characterized by hypereosinophilia and asthma with frequent sinonasal involvement, although multiple organs can be affected, including the heart, lungs, skin, gastrointestinal tract, kidneys, and nervous system. IL-5 production is pathogenetically central for the development of the disease by promoting proliferation, transvascular migration and functional activation of eosinophils. The degree of blood and tissue eosinophilia appears to be associated with disease pathogenesis and eosinophil depletion represents a promising treatment approach for EGPA. We prospectively evaluated the efficacy and safety of a low dose (100 mg q4w), 12-month course of mepolizumab, an anti-IL-5 monoclonal antibody, in eight patients with severe asthma and active EGPA. Patients were recruited by the tertiary care center of Clinical Immunology and Allergy, University of Naples Federico II. The following outcomes were assessed before (T0), and after 6 (T6) and 12 months (T12) of mepolizumab treatment: Birmingham Vasculitis Activity Score (BVAS), prednisone intake, Sino-Nasal Outcome Test (SNOT-22), Total Endoscopic Polyp Score (TENPS), Asthma Control Test (ACT), Forced Expiratory Volume one second (FEV1)%, blood eosinophilia. BVAS score significantly decreased showing a sharp reduction in disease activity score. Clinical improvements in terms of sinonasal scores and asthma symptoms were observed, in parallel with a drastic drop in eosinophil blood count. Prednisone intake was significantly reduced. In two patients, asthma exacerbations led to discontinuation in mepolizumab therapy after 6 and 12 months despite BVAS reduction. Mepolizumab treatment was well tolerated, and no severe adverse drug effects were registered. In conclusion, our 12-month real-life study suggests that mepolizumab may be beneficial and safe in active EGPA patients by improving disease activity score, sinonasal and asthma outcomes while reducing the burden of prednisone intake.

Energy storage in salamanders' tails: the role of sex and ecology.

In vertebrates, the main tissue devoted to energy storage is the adipose tissue. In salamanders, energy reserves can also be stored in the adipose tissues of the tail. Therefore, we evaluated if energy storage in salamanders' tails is related to individual body condition, life cycle and environmental constraints. We calculated a scaled measure of tail width for 345 salamanders belonging to six Mediterranean taxa exhibiting wide phylogenetic, behavioural and ecological variation. We related this measure to the Scaled Mass Index (SMI), a body condition index which reliably predicts body fat. We found significant relationships between the SMI and scaled tail width in the terrestrial Spectacled salamander and Alpine salamanders, independently of sex. At the same time, we found that energy storage in the tail is maximum in Alpine Salamanders, which experience reduced activity periods and restricted access to resources. Conversely, we found a significant effect of sex in Imperial cave salamanders, where females store reserves in the tail to counterbalance resource investment in parental care, and in Corsican Brook Newts, where the reproductive function of males' tails may imply a greater tail width. Finally, in the biphasic Great Crested Newt, tail width was not related to SMI in both sexes.

Topical photodynamic therapy in the treatment of benign oral mucosal lesions: A systematic review.

BACKGROUND: The introduction of photodynamic therapy (PDT) in various branches of the dental field such as endodontics, implantology, periodontology, and restorative dentistry and oral medicine has become useful in recent decades. This systematic review presents an overview of the literature to evaluate the usefulness of topical PDT for the treatment of benign oral soft tissue lesions and to identify limitations in prior studies to improve PDT applications. METHODS: We performed a review of the literature using different search engines (PubMed, ISI Web of Science, and the Cochrane Library) employing MeSH terms such as "Photodynamic therapy" and "PDT" in conjunction with other terms. We utilized the Population, Intervention, Comparison, Outcomes, and Study design (PICOS) method to define our study eligibility criteria. RESULTS: Initial results were 1513. Finally, there were only 21 studies that met our selection criteria. We divided the 21 selected items into two groups: inflammatory diseases and infective diseases. CONCLUSIONS: Although topical PDT is an easy to perform and well-tolerated treatment and appears to be a valid method with promising results in the treatment of benign lesions of the oral cavity's soft tissues, further studies are needed to complete the current knowledge of this technique.

The potential role of Photodynamic therapy in oral premalignant and malignant lesions: A systematic review.

BACKGROUND: Photodynamic therapy (PDT) is considered as a valid treatment option in various branches of dentistry. This systematic review aims to evaluate the usefulness of PDT for treatment of oral premalignant and malignant lesions. METHODS: The MeSH terms "Photodynamic therapy" and "PDT," in combination with other terms, have been searched by three search engines (PubMed, ISI Web of Science, and the Cochrane Library), and a systematic review has been performed. The Population, Intervention, Comparison, Outcomes, and Study design (PICOS) has been applied as method to outline our study eligibility criteria. Risk of Bias in Non-randomized Studies of Intervention (ROBINS-I) has been performed too. RESULTS: Initial results were 1513. Definitely, 27 studies met our selection criteria. CONCLUSIONS: Topical PDT is an easy to perform technique, well-tolerated treatment and it appears to be an effective method with encouraging achievements in the treatment of premalignant and malignant lesions of the soft tissues of the oral cavity; nevertheless more studies are required to integrate the up-to-date experience of this application.

Cross-sectional study on the quality of oral lichen planus videos on YouTube™.

BACKGROUND: YouTube™ is one of the most used platforms for patients looking for health-related information. The purpose of this cross-sectional study was to analyze the available information about oral lichen planus on YouTube™ and how users interact with it. METHODS: A YouTube™ search for oral lichen planus was performed, setting English UK (language) and United Kingdom (country). Two hundred and fifteen results were screened, and 36 videos met the inclusion criteria. Videos' quality was evaluated using the DISCERN and the Global Quality Scale tools, and by categorizing them through quality assessment, source, duration, views, likes, and dislikes of each video were noted. RESULTS: According to quality assessments, 55.6% of the videos were classified as useful, while the 35.1% were classified as misleading/dangerous. The DISCERN and GQS values were generally low (31.56 ± 10.38 and 2.33 ± 1.07, respectively); DISCERN and GQS were positively correlated with the video length and negatively correlate with the data of upload (p < 0.05). CONCLUSIONS: This study corroborates the results of others that a great number of health-related videos available on YouTube™ feature misleading or potentially dangerous information; although the quality seems to slightly improve over time, medical associations and researchers ought to plan strategies aimed at improving the quality of the information delivered through YouTube™ and other social media.

The Role of a Deep Neuromuscular Block in the Treatment of Mandibular Subcondylar Fractures.

ABSTRACT: Mandibular fractures are the third most frequents maxillo-facial fractures. Most frequent site is the subcondylar region. Different approaches to reach subcondylar region, have been described. In the study was evaluated the advantages of neuromuscular block during endoscopic surgery for subcondylar fractures. Twenty-five patients affected by subcondylar fractures were enrolled in this study and divided in 2 groups; group A: patients who received an intraoperative booster of curare during surgical procedure and group B patients who underwent surgery treated without the intraoperative booster of curare. All patients were treated successfully by endoscope-assisted transoral approach. The analysis of time required for surgery showed a reduction in group A comparing to group B. The mean time for surgery for the patients in group B with displacement between 0° and 45° was 170 minutes, and for 45° to 90° was 230 minutes. In group A, the mean time was 117.5 minutes for patients with condylar displacement between 0° and 45°, and 147.5 minutes for the other group. In conclusion, deep neuromuscular block seems to improve the surgical conditions in patients undergoing subcondylar endoscopic assisted surgery, further study needs to assess this surgical technique in order to better define this surgical protocol.

Oral Microbiota Features in Subjects with Down Syndrome and Periodontal Diseases: A Systematic Review.

Down syndrome (DS) is a genetic disorder associated with early-onset periodontitis and other periodontal diseases (PDs). The present work aimed to systematically review the scientific literature reporting studies in vivo on oral microbiota features in subjects with DS and related periodontal health and to highlight any correlation and difference with subjects not affected by DS, with and without PDs. PubMed, Web of Science, Scopus and Cochrane were searched for relevant studies in May 2021. The participants were subjects affected by Down syndrome (DS) with and without periodontal diseases; the study compared subjects with periodontal diseases but not affected by DS, and DS without periodontal diseases; the outcomes were the differences in oral microbiota/periodontopathogen bacterial composition among subjects considered; the study design was a systematic review. Study quality was assessed with risk of bias in non-randomized studies of interventions (ROBINS-I). Of the 954 references retrieved, 26 studies were considered. The conclusions from the qualitative assessment of the papers revealed an increasing knowledge over the last years of the microbiota associated with DS and their periodontal diseases, in comparison with healthy subjects and subjects with other kinds of mental disabilities. Few data have emerged on the mycobiome and virobiome of DS, hence, further investigations are still necessary.

The WeanCare nutritional intervention in institutionalized dysphagic older people and its impact on nursing workload and costs: A quasi-experimental study.

AIM: The aim of this study is to explore how a nutritional intervention that improves the biochemical and functional profile of dysphagic older people impacts on nursing workload and costs for nursing homes. BACKGROUND: Dysphagic institutionalized older people particularly at risk of malnutrition require more intensive support from nursing staff and higher costs for nursing homes. METHOD: This is an open pre-post longitudinal multicentre quasi-experimental study without a control group. RESULTS: There is a significant reduction in the number of enemas (from 3.51 to 1.11 enemas), with an average nursing workload reduction from 52 to 16 min per patient every month. Each nurse also spent 20 h less per patient every month spoon-feeding. This resulted in nursing staff cost savings. CONCLUSIONS: The nutritional intervention led to a significantly better quality of life for the patients manifested through increased independence and social engagement. This reduced workload for nursing staff and costs for nursing home administrators. IMPLICATIONS FOR NURSING MANAGEMENT: Sensitive, targeted nutritional interventions have the potential to improve nursing home residents' quality of life and enable a more efficient use of resources. This study revealed reduced workload and cost savings due to less time spent administering enemas and spoon-feeding, in addition to reduced malnutritional consequences.
