Polysaccharides (PSAs) are carbohydrate-based macromolecules widely used in the biomedical field, either in their pure form or in blends/nanocomposites with other materials. The relationship between structure, properties, and functions has inspired scientists to design multifunctional PSAs for various biomedical applications by incorporating unique molecular structures and targeted bulk properties. Multiple strategies, such as conjugation, grafting, cross-linking, and functionalization, have been explored to control their mechanical properties, electrical conductivity, hydrophilicity, degradability, rheological features, and stimuli-responsiveness. For instance, custom-made PSAs are known for their worldwide biomedical applications in tissue engineering, drug/gene delivery, and regenerative medicine. Furthermore, the remarkable advancements in supramolecular engineering and chemistry have paved the way for mission-oriented biomaterial synthesis and the fabrication of customized biomaterials. These materials can synergistically combine the benefits of biology and chemistry to tackle important biomedical questions. Herein, we categorize and summarize PSAs based on their synthesis methods, and explore the main strategies used to customize their chemical structures. We then highlight various properties of PSAs using practical examples. Lastly, we thoroughly describe the biomedical applications of tailor-made PSAs, along with their current existing challenges and potential future directions.

BACKGROUND: Augmentation/mastopexy represents one of the most complex procedures in the setting of cosmetic surgery, and there is still an ongoing debate about the most suitable approach to undertake to avoid major complications and deliver the desired result. The present study aims to offer a further contribute to the topic by presenting our personal experience with an implant-guided tailor-made mastopexy technique to manage moderate breast ptosis and hypotrophy.
METHODS: A retrospective analysis of our database was carried out, and a total of 194 women who underwent a tailor-made resection pattern mastopexy plus implant from November 2016 to December 2021 were enrolled. All patients included in the study presented breast hypoplasia and ptosis classified as Regnault grade II. At the first-year follow-up visit, patients received an anonymous written questionnaire that addressed their self-perception of cosmetic results and overall satisfaction.
RESULTS: The technique presented in the study showed a favorable safety profile with a total complication rate accounting for an 8.2% and an overall reoperation rate as low as 4.6%. Major concerns including wound dehiscence, implant exposure, and nipple necrosis are not reported. Patients\' self-reported outcomes revealed high satisfaction rates and stable results in the long-term follow-up.
CONCLUSIONS: The described approach ensures proper reshaping together with the desired increased breast volume minimizing the chance of implant exposure due to wound dehiscence or any sort of tissue necrosis from devascularized skin edges. The surgical procedure described herein is safe and reliable.

Non-isocyanate polyurethanes (NIPUs) based on biobased polyamines and polycarbonates are a sustainable alternative to conventional polyurethanes (PU). This article discloses a novel method to control the crosslinking density of fully biobased isocyanate-free polyurethanes, synthesized from triglycerides carbonated previously in scCO2 and different diamines, such as ethylenediamine (EDA), hexamethylenediamine (HMDA) and PriamineTM-1075 (derived from a dimerized fatty acid). As capping substances, water or bioalcohols are used in such a way that the crosslinking density can be adjusted to suit the requirements of the intended application. An optimization of the NIPU synthesis procedure is firstly carried out, establishing the polymerization kinetics and proposing optimal conditions set for the synthesis of the NIPUs. Then, the influence of the partial blocking of the active polymerization sites of the carbonated soybean oil (CSBO), using monofunctional amines, on the physical properties of the NIPUS is explored. Finally, the synthesis of fully biobased NIPUs with a targeted crosslinking density is achieved using hybrid NIPUs, employing partially carbonated oil and H2O or ethanol as blockers to achieve the desired physical properties in a very precise manner.

UNASSIGNED: The online intervention Runfitcheck was developed to stimulate injury-preventive behaviour among adult novice runners.
UNASSIGNED: This study evaluated the effectiveness of Runfitcheck on injury-preventive behaviour among adult novice runners.
UNASSIGNED: A randomised controlled trial was conducted among adult novice runners. The intervention group had access to the Runfitcheck intervention, the control group performed their running activities as usual. One, three, and five months after enrolment, participants reported retrospectively what they had done regarding injury-preventive behaviour (operationalised as (i) using a (personalised) training schedule; (ii) performing strength and technique exercises; and (iii) performing a warm-up routine prior to running). Relative Risks (RR) and 95% Confidence Interval (95%CI) were used to analyse behavioural change.
UNASSIGNED: The intervention group (n=715) searched more often for information about a warm-up routine (RR 1.211; 95%CI 1.080-1.357), and added more often strength exercises to their warm-up routine (RR 1.228; 95%CI 1.092-1.380). The intervention group performed more often running technique exercises compared to the control group (n=696) (RR 1.134; 95%CI 1.015-1.267), but less often strength exercises (RR 0.865 (95%CI 0.752-0.995). Within the group of runners that did not perform any warm-up routine at enrolment (n=272), the intervention group started to perform a regular warm-up routine more often than the control group (RR 1.461; 95%CI 1.084-1.968). No significant results were found for using a training schedule.
UNASSIGNED: The online intervention Runfitcheck was effective in stimulating aspects of injury-preventive behaviour in adult novice runners, mostly related to a warm-up routine.

UNASSIGNED: The two ends of arteriovenous graft (AVG) are anastomosed to the upper limb vessels by surgery for hemodialysis therapy. However, the size of upper limb vessels varies to a large extent among different individuals.
UNASSIGNED: According to the shape and size of neck vessels quantified from the preoperative computed tomography angiographic scan, the ethylene-vinyl acetate (EVA)-based AVG was produced in H-shape by the three-dimensional (3D) printer and then sterilized. This study investigated the function of this novel 3D-printed AVG in vitro and in vivo.
UNASSIGNED: This 3D-printed AVG can be implanted in the rabbit\'s common carotid artery and common jugular vein with ease and functions in vivo. The surgical procedure was quick, and no suture was required. The blood loss was minimal, and no hematoma was noted at least 1 week after the surgery. The blood flow velocity within the implanted AVG was 14.9 ± 3.7 cm/s. Additionally, the in vitro characterization experiments demonstrated that this EVA-based biomaterial is biocompatible and possesses a superior recovery property than ePTFE after hemodialysis needle cannulation.
UNASSIGNED: Through the 3D printing technology, the EVA-based AVG can be tailor-made to fit the specific vessel size. This kind of 3D-printed AVG is functioning in vivo, and our results realize personalized vascular implants. Further large-animal studies are warranted to examine the long-term patency.

The modification of an easily available resource like paper to circumvent expensive or intensive sample pretreatment could be the answer to sample analysis in resource-poor regions. Therefore, a novel on-paper device combining sample collection with affinity sample pretreatment is introduced here. Universal smart affinity samplers are produced by a simple KIO4-mediated oxidation of cellulose, which functionalizes the paper. This is followed by immobilization of streptavidin. Streptavidin serves as a universal anchor for biotinylated antibodies, enabling simple preparation of tailor-made affinity samplers. The functionality of the device was tested using a model protein (human chorionic gonadotropin, hCG) and biotinylated anti-hCG antibodies for affinity capture. In a laboratory setting, the performance was demonstrated, and a 14-fold increase of target binding compared to binding without bmAb was achieved. The recovery of hCG captured with bmAb-treated samplers was determined to be 33% and comparable to previously described affinity capture approaches. Application of the smart affinity samplers to human serum containing hCG showed an R2 of 0.98 (200-1000 pg mL-1), precision of ≤ 9.1% RSD, and estimated limit of detection of 65 pg mL-1. Although further optimization and validation are necessary prior to application to real samples in clinical settings, the potential of the device for use in determination of low abundant biomarkers in complex samples has been demonstrated.

Mannosylerythritol lipids (MELs) are a type of glycolipid biosurfactant produced by basidiomycetous yeasts, most notably those belonging to the genera Pseudozyma and Ustilago. Mannosylerythritol lipids are environmentally friendly and possess many unique functions, such as gene delivery, bio-activation, and human skin repair, and thus have potential applications in cosmetic, pharmaceutical, agriculture, food, and environmental industries. However, MELs will require overcoming same issues related to the commercialization, e.g., expansion of the structure and function variety and cost reduction. In the past decade, various studies have attempted to tailor production of targeted MELs in order to expand the utility of these biosurfactants. Moreover, the rapid development of genomic sequencing techniques will enhance our ability to modify MEL producers. In this review, we focus on current research into the tailored production of MELs, including conventional and advanced approaches.

Despite the introduction of evidence based guidelines and practical courses, the incidence of postpartum hemorrhage shows an increasing trend in developed countries. Substandard care is often found, which implies an inadequate implementation in high resource countries. We aimed to reduce the gap between evidence-based guidelines and clinical application, by developing a strategy, tailored to current barriers for implementation.
The development of the implementation strategy consisted of three phases, supervised by a multidisciplinary expert panel. In the first phase a framework of the strategy was created, based on barriers to optimal adherence identified among professionals and patients together with evidence on effectiveness of strategies found in literature. In the second phase, the tools within the framework were developed, leading to a first draft. In the third phase the strategy was evaluated among professionals and patients. The professionals were asked to give written feedback on tool contents, clinical usability and inconsistencies with current evidence care. Patients evaluated the tools on content and usability. Based on the feedback of both professionals and patients the tools were adjusted.
We developed a tailored strategy to improve guideline adherence, covering the trajectory of the third trimester of pregnancy till the end of the delivery. The strategy, directed at professionals, comprehending three stop moments includes a risk assessment checklist, care bundle and time-out procedure. As patient empowerment tools, a patient passport and a website with patient information was developed. The evaluation among the expert panel showed all professionals to be satisfied with the content and usability and no discrepancies or inconsistencies with current evidence was found. Patients\' evaluation revealed that the information they received through the tools was incomplete. The tools were adjusted accordingly to the missing information.
A usable, tailored strategy to implement PPH guidelines and practical courses was developed. The next step is the evaluation of the strategy in a feasibility trial.

OBJECTIVE: To examine the efficacy of rehabilitation for elderly individuals with dementia at intermediate facilities between hospitals and home, based on the policies for elderly individuals to promote community-based care at home and dehospitalization.
METHODS: Participants were older adults with dementia newly admitted to intermediate facilities. A total of 158 in the intervention group who claimed Long-Term Care Insurance for three consecutive months, and 54 in the control group were included in the analysis. The interventions were carried out in a tailor-made manner to meet individual needs. The personal sessions were carried out three times a week for 3 months after admission by physical, occupational or speech therapists. Outcome measures were cognitive tests (Hasegawa Dementia Scale revised [HDS-R] and Mini-Mental State Examination), and observational assessments of dementia severity, activities of daily living (ADL), social activities, behavioral and psychological symptoms of dementia (BPSD) using a short version of the Dementia Disturbance Scale (DBD13), depressive mood, and vitality.
RESULTS: Significant improvement in the intervention group was shown in cognitive function measured by HDS-R (interaction F[1, 196] = 5.190, P = 0.024), observational evaluation of dementia severity (F[1,198] = 9.550, P = 0.002) and BPSD (DBD13; F[1,197] = 4.506, P = 0.035). Vitality, social activities, depressive mood and ADL were significantly improved only in the intervention group, although interaction was not significant.
CONCLUSIONS: Significant improvement by intervention was shown in multiple domains including cognitive function and BPSD. Cognitive decline and worsening of BPSD are predictors of care burden and hospitalization, thus intensive rehabilitation for dementia was beneficial for both individuals with dementia and their caregivers.
