Among the primary objectives of contemporary assisted reproductive technology research are achieving the births of healthy singletons and improving overall fertility outcomes. Substantial advances have been made in refining the selection of single embryos for transfer, with the aim of maximizing the likelihood of successful implantation. The principal criterion for this selection is embryo morphology. Morphological evaluation systems are based on traditional parameters, including cell count and fragmentation, pronuclear morphology, cleavage rate, blastocyst formation, and various sequential embryonic assessments. To reduce the incidence of multiple pregnancies and to identify the single embryo with the highest potential for growth, invasive techniques such as preimplantation genetic screening are employed in in vitro fertilization clinics. However, new approaches have been suggested for clinical application that do not harm the embryo and that provide consistent, accurate results. Noninvasive technologies, such as time-lapse imaging and omics, leverage morphokinetic parameters and the byproducts of embryo metabolism, respectively, to identify noninvasive prognostic markers for competent single embryo selection. While these technologies have garnered considerable interest in the research community, they are not incorporated into routine clinical practice and still have substantial room for improvement. Currently, the most promising strategies involve integrating multiple methodologies, which together are anticipated to increase the likelihood of successful pregnancy.

BACKGROUND: Decompressive craniectomy (DC) is a widely used procedure to alleviate high intracranial pressure. Multidisciplinary teams have designed and implemented external medical prototypes to improve patient life quality and avoid complications following DC in patients awaiting cranioplasty (CP), including 3D printing and plaster prototypes when available.
OBJECTIVE: This scoping review aims to understand the extent and type of evidence about innovative external prototypes for patients who undergo DC while awaiting CP.
METHODS: This scoping review will use the Joanna Briggs Institute methodology for scoping reviews. This scoping review will include noninvasive medical devices for adult patients who undergo DC while waiting for CP. The search strategy will be implemented in MEDLINE, Embase, Web of Science, Scielo, Scopus, and the World Health Organization (WHO) Global Health Index Medicus. Patent documents were also allocated in Espacenet, Google Patents, and the World Intellectual Property Organization (WIPO) database.
RESULTS: This scoping review is not subject to ethical approval as there will be no involvement of patients. The dissemination plan includes publishing the review findings in a peer-reviewed journal and presenting results at conferences that engage the most pertinent stakeholders in innovation and neurosurgery.
CONCLUSIONS: This scoping review will serve as a baseline to provide evidence for multidisciplinary teams currently designing these noninvasive innovations to reduce the risk of associated complications after DC, hoping that more cost-effective models can be implemented, especially in low- and middle-income countries.

OBJECTIVE: In recent years, noninvasive techniques are becoming conspicuous for diabetes detection. Sweat, tear, saliva, urine and breath-based methods showing prominent results in breath acetone detection which is considered as a biomarker of diabetes. A concrete relationship between breath acetone and BG helps in the development of devices for diabetes detection.
METHODS: The primary source for this study includes scholarly publications that primarily focus on the development of biosensors and systems for diabetes detection using acetone present in breath. Articles were analysed to examine various types of biosensors with their sensing materials to provide acetone detection limits. Recent noninvasive systems and products have been investigated and determine the relationship between breath acetone and BG levels.
RESULTS: Breath-based biosensor technologies are capable for diabetes detection. The acetone biosensor detection ranges from 100 ppb to 100 ppm, and it can applicable from room temperature to 400 °C. In healthy volunteers, acetone level ranges from 0.32 to 2.19 ppm, while patients with diabetes exhibit a wider range of 0.22-21 ppm depending on the biosensor, detection method, and clinical circumstances of patients and lab conditions.
CONCLUSIONS: This manuscript presents an extensive analysis of breath-based biosensors and their potential for detection of diabetes. Acetone detection methods are promising but unable to provide concrete correlation between breath acetone and blood glucose levels. The present study motivates the continued research and development of biosensors, and electronic devices to provide linear relationship of breath acetone and BG for noninvasive diabetes detection applications.

For diabetics, taking regular blood glucose measurements is crucial. However, traditional blood glucose monitoring methods are invasive and unfriendly to diabetics. Recent studies have proposed a biofluid-based glucose sensing technique that creatively combines wearable devices with noninvasive glucose monitoring technology to enhance diabetes management. This is a revolutionary advance in the diagnosis and management of diabetes, reflects the thoughtful modernization of medicine, and promotes the development of digital medicine. This paper reviews the research progress of noninvasive continuous blood glucose monitoring (CGM), with a focus on the biological liquids that replace blood in monitoring systems, the technical principles of continuous noninvasive glucose detection, and the output and calibration of sensor signals. In addition, the existing limits of noninvasive CGM systems and prospects for the future are discussed. This work serves as a resource for further promoting the development of noninvasive CGM systems.

Understanding facial anatomy is a key aspect for successful treatment of age-related changes manifested to facial tissues. Namely, changes to the facial muscles and their connective tissue framework result in an increased soft tissue laxity, leading to wrinkling, sagging, and altered texture. This review elaborates on the use of novel high intensity focused electrical stimulation (HIFES) and Synchronized RF technology to improve facial muscle tone and skin structure, focusing on the technology background and clinical aspects.

UNASSIGNED: Diabetes mellitus is a dominant metabolic disorder in the current fast paced culture; its prevalence is escalating worldwide and among all age groups. Guidelines recommend universal screening for diabetes; however, the uptake of these tests in individuals suggests challenges owing to invasive nature of blood collection. Thus, there arises the need for a noninvasive investigation for diabetes screening with a minimum paraphilia and for all medical settings.
UNASSIGNED: We have thus conducted a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, to quantify the association between diabetes and effectiveness of periodic acid-Schiff staining of exfoliative cytology as a screening method. MEDLINE, EMBASE, Cochrane, Scopus, Web of science, CINAHL, and Google Scholar were searched systematically for publications dated till July 20, 2022. Six studies (case-control cross-sectional) were selected and evaluated in depth. The statistical evaluation was done with a forest plot with odds ratio and weightage examined.
UNASSIGNED: It was proved that exfoliative cytology with periodic acid-Schiff (PAS) staining can be used as a screening test for diabetic status evaluation. The findings suggest that the aforesaid noninvasive test is a conclusive screening practice for diabetics.
UNASSIGNED: This systematic review and meta-analysis suggest that PAS staining in exfoliative cytology can be used as a noninvasive screening in diabetic individuals to assess the current level of blood glucose. Given the increased risk of diabetes worldwide, higher quality prospective evidence is suggested in larger sample sizes with other metabolic disorders, ethnicity, and oral disorders to further evaluate the plausibility of the results.

We review the research progress on noninvasive neural regulatory systems through system design and theoretical guidance. We provide an overview of the development history of noninvasive neuromodulation technology, focusing on system design. We also discuss typical cases of neuromodulation that use modern noninvasive electrical stimulation and the main limitations associated with this technology. In addition, we propose a closed-loop system design solution of the \"time domain\", \"space domain\", and \"multi-electrode combination\". For theoretical guidance, this paper provides an overview of the \"digital brain\" development process used for noninvasive electrical-stimulation-targeted modeling and the development of \"digital human\" programs in various countries. We also summarize the core problems of the existing \"digital brain\" used for noninvasive electrical-stimulation-targeted modeling according to the existing achievements and propose segmenting the tissue. For this, the tissue parameters of a multimodal image obtained from a fresh cadaver were considered as an index. The digital projection of the multimodal image of the brain of a living individual was implemented, following which the segmented tissues could be reconstructed to obtain a \"digital twin brain\" model with personalized tissue structure differences. The \"closed-loop system\" and \"personalized digital twin brain\" not only enable the noninvasive electrical stimulation of neuromodulation to achieve the visualization of the results and adaptive regulation of the stimulation parameters but also enable the system to have individual differences and more accurate stimulation.

Acne vulgaris, despite being one of the most common dermatological diseases, remains challenging to treat. Acne lesion location and type, skin tone, genetics, and environmental factors influence mono- or multimodal therapeutic decisions. Combination topical and oral treatments may successfully reduce lesion count; however, these agents take time to work, and side effects are not uncommon. The long-term therapeutic engagement required to treat acne may be too costly or burdensome for many patients, which may impact treatment adherence, which can negatively impact patient outcomes. There is increased interest in noninvasive acne treatments to reduce side effects, provide rapid results, and foster treatment adherence. TheraClearX® X Acne System combines broadband pulsed light and vacuum suction technology. The combination of these two treatment modalities mechanically clears congested follicles and targets endogenous porphyrins produced by Cutibacterium acnes and other acnegenic bacteria. This article describes the proposed mechanism of action, treatment advantages, examples of treatment protocols, and anecdotal results using this combination device in the treatment of acne.

The rising cancer incidence in patients with oral leukoplakia (OL) highlights the importance of identifying potential biomarkers for high-risk individuals and lesions because these biomarkers are useful in developing personalized management strategies for OL patients. This study systematically searched and analyzed the literature on potential saliva and serum biomarkers for OL malignant transformation.
PubMed and Scopus were searched for studies published up to April 2022. The primary outcome of this study was the difference in biomarker concentrations in saliva or serum samples from healthy control (HC), OL and oral cancer (OC) populations. Cohen\'s d with 95% credible interval was calculated and pooled using the inverse variance heterogeneity method.
A total of seven saliva biomarkers were analyzed in this paper, including interleukin-1alpha, interleukin-6 (IL-6), interleukin-6-8, tumor necrosis factor alpha (TNF-α), copper, zinc, and lactate dehydrogenase. IL-6 and TNF-α exhibited statistically significant deviations in comparisons between HC versus OL and OL versus OC. A total of 13 serum biomarkers were analyzed, including IL-6, TNF-α, C-reactive protein, total cholesterol, triglycerides, high-density lipoproteins, low-density lipoproteins, albumin, protein, β2-microglobulin, fucose, lipid-bound sialic acid (LSA), and total sialic acid (TSA). LSA and TSA exhibited statistically significant deviations in comparisons between HC versus OL and OL versus OC.
IL-6 and TNF-α in saliva have strong predictive values for OL deterioration, and LSA and TSA concentration levels in serum also have the potential to serve as biomarkers for OL deterioration.

A major challenge in ART is to select high-quality oocytes and embryos. The metabolism of oocytes and embryos has long been linked to their viability, suggesting the potential utility of metabolic measurements to aid in selection. Here, we review recent work on noninvasive metabolic imaging of cumulus cells, oocytes, and embryos. We focus our discussion on fluorescence lifetime imaging microscopy (FLIM) of the autofluorescent coenzymes NAD(P)H and flavine adenine dinucleotide (FAD+), which play central roles in many metabolic pathways. FLIM measurements provide quantitative information on NAD(P)H and FAD+ concentrations and engagement with enzymes, leading to a robust means of characterizing the metabolic state of cells. We argue that FLIM is a promising approach to aid in oocyte and embryo selection.
