Sonogenetics in the Treatment of Chronic Diseases: A New Method for Cell Regulation.

Sonogenetics is an innovative technology that integrates ultrasound with genetic editing to precisely modulate cellular activities in a non-invasive manner. This method entails introducing and activating mechanosensitive channels on the cell membrane of specific cells using gene delivery vectors. When exposed to ultrasound, these channels can be manipulated to open or close, thereby impacting cellular functions. Sonogenetics is currently being used extensively in the treatment of various chronic diseases, including Parkinson's disease, vision restoration, and cancer therapy. This paper provides a comprehensive review of key components of sonogenetics and focuses on evaluating its prospects and potential challenges in the treatment of chronic disease.

Restorative Treatments for Cervical Spinal Cord Injury, a Narrative Review.

A narrative review. To summarize relevant data from representative studies investigating upper limb restorative therapies for cervical spinal cord injury. Cervical spinal cord injury (SCI) is a debilitating condition resulting in tetraplegia, lifelong disability, and reduced quality of life. Given the dependence of all activities on hand function, patients with tetraplegia rank regaining hand function as one of their highest priorities. Recovery from cervical SCI is heterogeneous and often incomplete; currently, various novel therapies are under investigation to improve neurological function and eventually better quality of life in patients with tetraplegia. In this article, a narrative literature review was performed to identify treatment options targeting the restoration of function in patients with cervical SCI. Studies were included from available literature based on the availability of clinical data and whether they are applicable to restoration of arm and hand function in patients with cervical SCI. We describe relevant studies including indications and outcomes with a focus on arm and hand function. Different treatment modalities described include nerve transfers, tendon transfers, spinal cord stimulation, functional electrical stimulation, non-invasive brain stimulation, brain-machine interfaces and neuroprosthetics, stem cell therapy, and immunotherapy. As the authors' institution leads one of the largest clinical trials on nerve transfers for cervical SCI, we also describe how patients undergoing nerve transfers are managed and followed at our center. While complete recovery from cervical spinal cord injury may not be possible, novel therapies aimed at the restoration of upper limb motor function have made significant progress toward the realization of complete recovery.

Wide-angle simulated artificial vision enhances spatial navigation and object interaction in a naturalistic environment.

Vision restoration approaches, such as prosthetics and optogenetics, provide visual perception to blind individuals in clinical settings. Yet their effectiveness in daily life remains a challenge. Stereotyped quantitative tests used in clinical trials often fail to translate into practical, everyday applications. On the one hand, assessing real-life benefits during clinical trials is complicated by environmental complexity, reproducibility issues, and safety concerns. On the other hand, predicting behavioral benefits of restorative therapies in naturalistic environments may be a crucial step before starting clinical trials to minimize patient discomfort and unmet expectations.
Approach. To address this, we leverage advancements in virtual reality technology to conduct a fully immersive and ecologically valid task within a physical artificial street environment. As a case study, we assess the impact of the visual field size in simulated artificial vision for common outdoor tasks.
Main Results. We show that a wide visual angle (45°) enhances participants' ability to navigate and solve tasks more effectively, safely, and efficiently. Moreover, it promotes their learning and generalization capability. Concurrently, it changes the visual exploration behavior and facilitates a more accurate mental representation of the environment. Further increasing the visual angle beyond this value does not yield significant additional improvements in most metrics.
Significance. We present a methodology combining augmented reality with a naturalistic environment, enabling participants to perceive the world as patients with retinal implants would and to interact physically with it. Combining augmented reality in naturalistic environments is a valuable framework for low vision and vision restoration research.

Oral health in obese children common findings, prevention, treatment and outcome

Childhood obesity is a significant global public health issue, closely linked to various oral health challenges, including dental caries, periodontal disease, and malocclusion. Obese children are more prone to these dental problems due to dietary habits that include high sugar and carbohydrate intake, poor oral hygiene practices, and systemic inflammation. This review explores the common oral health issues faced by obese children and emphasizes the importance of preventive strategies and tailored treatment approaches. Preventive measures include promoting healthy dietary habits, improving oral hygiene practices, and ensuring regular dental check-ups. Dietary modifications, such as reducing the intake of sugary snacks and beverages, play a crucial role in preventing tooth decay and other dental problems. Educating children and caregivers about proper brushing and flossing techniques and the use of fluoride toothpaste and dental sealants further supports oral health. Regular dental visits allow for early detection and management of dental issues, with professional cleanings, fluoride treatments, and appropriate restorative and periodontal therapies being integral components of care. The outcomes of these comprehensive treatment strategies are generally positive, leading to improved oral health and overall quality of life for obese children. Multidisciplinary collaboration among healthcare providers, including dentists, pediatricians, and nutritionists, is essential to develop effective care plans that address both obesity and oral health. This integrated approach ensures that obese children receive holistic care that promotes lifelong healthy habits, reducing the risk of future dental and systemic health problems. The review underscores the necessity of a concerted effort to address the intertwined issues of obesity and oral health in children, highlighting the potential for significant health improvements through targeted prevention and treatment strategies.

Treatment Among Commercial and Medicaid-Insured Adults With Incident Chronic Pain Episodes

Analyses of health care data can reveal utilization of treatment options that comprise a multidisciplinary approach to chronic pain management. This retrospective cohort study aimed to characterize treatments among commercially versus Medicaid-insured adults with incident episodes of chronic pain. We used MarketScan data to identify patients with diagnoses for conditions associated with chronic pain, assess procedure codes that align with broad categories of treatment options, and compare receipt of treatments by insurance type. Among enrollees aged ≥18 years, 4,254,818 adults with commercial insurance and 583,369 with Medicaid met continuous enrollment criteria and had no chronic pain episodes in 2017. Among patients with incident chronic pain episodes during 2018 to 2020, we determined the proportions receiving different categories of treatment options during the year following diagnosis. Cohen’s h determined meaningful differences by insurance. Study cohorts included 1,095,358 commercial (mean [standard deviation] age, 47.3 [13.3] years; 54.3% women) and 176,607 Medicaid adults (38.1 [12.7] years; 70.6% women) with incident chronic pain episodes during 2018 to 2020. More commercial than Medicaid patients received restorative therapies such as physical therapy (38.6% vs 19.2%), complementary or integrative care such as chiropractic treatment (31.1% vs 9.0%), and 2 or more different types of nonmedication treatment procedures (34.1% vs 16.3%). Median days to treatments were shorter for commercial patients. Disparities in the provision, patterns, and timing of treatments by insurance suggest differential access to the full range of treatment options early during the course of care and identify opportunities to align coverage and reimbursement policies with current practice guidelines. PerspectiveThis analysis of medical claims for patients with incident chronic pain episodes found disparities in the provision, patterns, and timing of treatments by insurance type. These results suggest differential access to evidence-based treatment options early during care and identify opportunities to align coverage and reimbursement policies with current practice guidelines.

Prospective case series study on the survival rates of occlusal polymethyl methacrylate veneers as a semipermanent therapy in patients with severe pathologic tooth wear.

To evaluate the survival rate of minimally invasive semipermanent occlusal polymethyl methacrylate (PMMA) onlays/veneers in previous temporomandibular disorder (TMD) patients with severe tooth wear and with a loss of vertical dimension after up to 7 years. This case series was designed as a follow-up evaluation with consecutive patient recruitment. All patients bearing the indication for this kind of rehabilitation were treated by the same clinician using the same adhesive methodology. The study included 22 patients (3 men/19 women), with a mean ± SD age of 50.7 ± 11.6 years. Controls followed within the first 4 weeks (and subsequently as required). Failure criteria included damage by fracture, chipping, and retention loss. Survival rates were determined based on the Kaplan-Meier analysis. 328 semipermanent occlusal/incisal veneers were included (142 maxillary/186 mandibular teeth). Almost 80% of the restorations were in place and in function when starting the follow-up treatment after 180 days; failures predominantly occurred within the first 3 to 6 months but proved reparable. Depending on the patients' priorities, scheduled replacements followed successively, and more than 65% did not show repair or any renewal needs for more than 360 days. Within the limitations of this study the survival rates of occlusal veneers made of PMMA were sufficiently high to allow for consecutive treatment of the respective teeth by means of permanent restorations while preserving the restored vertical dimension. In patients with severe tooth wear and a TMD history, semipermanent restorative therapy with occlusal PMMA onlays/veneers would seem a noteworthy option.

Approach to the child and adolescent with Adrenal Insufficiency.

The management of adrenal insufficiency is challenging, and the overall goals of treatment are to prevent life-threatening adrenal crises, to optimize linear growth, to control androgen levels without overdosing in subjects with congenital adrenal hyperplasia (CAH) and to improve quality of life in affected individuals. Standard glucocorticoid formulations fail to replicate the circadian rhythm of cortisol and control the adrenal androgen production driven by adrenocorticotropic hormone. In order to personalize and tailor glucocorticoid therapy and to improve patient outcomes, new pharmacological strategies have been developed that best mimic physiological cortisol secretion. Novel therapeutic approaches in the management of adrenal insufficiency include new ways to deliver circadian cortisol replacement as well as various adjunctive therapies to reduce androgen production and/or androgen action/effects. Preclinical studies are exploring the role of restorative cell-based therapies, and a first recombinant adeno-associated virus-based gene therapy is also being developed in humans with CAH. In this article, we present three illustrative cases of adrenal insufficiency with different underlying etiologies and times of presentation. Diagnostic and management processes are discussed with emphasis on treatment and outcomes. We have also provided the most up-to-date evidence for the tailored management of children and adolescents with adrenal insufficiency.

Dissecting glial scar formation by spatial point pattern and topological data analysis

Glial scar formation represents a fundamental response to central nervous system (CNS) injuries. It is mainly characterized by a well-defined spatial rearrangement of reactive astrocytes and microglia. The mechanisms underlying glial scar formation have been extensively studied, yet quantitative descriptors of the spatial arrangement of reactive glial cells remain limited. Here, we present a novel approach using point pattern analysis (PPA) and topological data analysis (TDA) to quantify spatial patterns of reactive glial cells after experimental ischemic stroke in mice. We provide open and reproducible tools using R and Julia to quantify spatial intensity, cell covariance and conditional distribution, cell-to-cell interactions, and short/long-scale arrangement, which collectively disentangle the arrangement patterns of the glial scar. This approach unravels a substantial divergence in the distribution of GFAP+ and IBA1+ cells after injury that conventional analysis methods cannot fully characterize. PPA and TDA are valuable tools for studying the complex spatial arrangement of reactive glia and other nervous cells following CNS injuries and have potential applications for evaluating glial-targeted restorative therapies.

Innovative therapies for hair restoration and rejuvenation: an overview

Hair loss and baldness are incredibly common conditions with a significant negative impact on a person's psychosocial functioning and quality of life. Only two drug treatments are currently available for the treatment of hair loss, but side effects render their usage limited. Substantial advancements in hair restoration and rejuvenation in aesthetic medicine have been achieved, particularly in non-surgical treatment options. Francesca Ramadan supplies an overview of some of the options most commonly offered in aesthetics clinics.

Altered brain function during movement programming is linked with motor deficits after stroke: a high temporal resolution study.

Stroke leads to motor deficits, requiring rehabilitation therapy that targets mechanisms underlying movement generation. Cortical activity during the planning and execution of motor tasks can be studied using EEG, particularly via the Event Related Desynchronization (ERD). ERD is altered by stroke in a manner that varies with extent of motor deficits. Despite this consensus in the literature, defining precisely the temporality of these alterations during movement preparation and performance may be helpful to better understand motor system pathophysiology and might also inform development of novel therapies that benefit from temporal resolution. Patients with chronic hemiparetic post-stroke (n = 27; age 59 ± 14 years) and age-matched healthy right-handed control subjects (n = 23; 59 ± 12 years) were included. They performed a shoulder rotation task following the onset of a stimulus. Cortical activity was recorded using a 256-electrode EEG cap. ERD was calculated in the beta frequency band (15-30 Hz) in ipsilesional sensorimotor cortex, contralateral to movement. The ERD was compared over time between stroke and control subjects using permutation tests. The correlation between upper extremity motor deficits (assessed by the Fugl-Meyer scale) and ERD over time was studied in stroke patients using Spearman and permutation tests. Patients with stroke showed on average less beta ERD amplitude than control subjects in the time window of -350 to 50 ms relative to movement onset (t(46) = 2.8, p = 0.007, Cohen's d = 0.31, 95% CI [0.22: 1.40]). Beta-ERD values correlated negatively with the Fugl-Meyer score during the time window -200 to 400 ms relative to movement onset (Spearman's r = -0.54, p = 0.003, 95% CI [-0.77 to -0.18]). Our results provide new insights into the precise temporal changes of ERD after hemiparetic stroke and the associations they have with motor deficits. After stroke, the average amplitude of cortical activity is reduced as compared to age-matched controls, and the extent of this decrease is correlated with the severity of motor deficits; both were true during motor programming and during motor performance. Understanding how stroke affects the temporal dynamics of cortical preparation and execution of movement paves the way for more precise restorative therapies. Studying the temporal dynamics of the EEG also strengthens the promising interest of ERD as a biomarker of post-stroke motor function.

Arterial specification precedes microvascular restitution in the peri-infarct cortex that is driven by small microvessels.

Evaluation of microvascular networks was impeded until recently by the need of histological tissue sectioning, which precluded 3D analyses. Using light-sheet microscopy, we investigated microvascular network characteristics in the peri-infarct cortex of mice 3-56 days after transient middle cerebral artery occlusion. In animal subgroups, the sphingosine-1-phosphate analog FTY720 (Fingolimod) was administered starting 24 hours post-ischemia. Light-sheet microscopy revealed a striking pattern of microvascular changes in the peri-infarct cortex, that is, a loss of microvessels, which was most prominent after 7 days and followed by the reappearance of microvessels over 56 days which revealed an increased branching point density and shortened branches. Using a novel AI-based image analysis algorithm we found that the length density of microvessels expressing the arterial specification marker α-smooth muscle actin markedly increased in the peri-infarct cortex already at 7 days post-ischemia. The length and branch density of small microvessels, but not of intermediate or large microvessels increased above pre-ischemic levels within 14-56 days. FTY720 increased the length and branch density of small microvessels. This study demonstrates long-term alterations of microvascular architecture post-ischemia indicative of increased collateralization most notably of small microvessels. Light-sheet microscopy will greatly advance the assessment of microvascular responses to restorative stroke therapies.

Clinical Outcome Success of Silver-Modified Atraumatic Restorative Treatment (SMART) in Treating Children with Dental Caries in Primary Teeth: A Systematic Review

Abstract Objective: A novel approach called silver-modified atraumatic restorative therapy (SMART) integrates glass ionomer cement (GIC) restorations with silver diamine fluoride (SDF). This new method combines the ability of GIC to seal the tooth and sever the nutrition that bacteria require to proliferate, with the bactericidal power of SDF. The purpose of this review is to evaluate and compare the available data regarding the efficacy of the SMART approach in treating children's carious primary teeth. Materials and Methods: The earliest date accessible up until February 15, 2024, was thoroughly searched in databases including Scopus, PubMed, Cochrane, Science Direct, Lilacs, Science Direct, Web of Science, and Google Scholar. The review only comprised randomized controlled trials. The PICO strategy (P: Children with dental caries in primary teeth; I: SMART; C: Conventional drill and fill method or atraumatic restorative treatment [ART] therapy; O: Clinical success) was adopted. Risk of bias assessment and quality of evidence were assessed using the RoB-2 tool and GRADE tool, respectively. Results: Four full-text publications that met the eligibility criteria underwent additional processing for data extraction and qualitative analysis. In three studies, no difference was found in the clinical performance of SMART and conventional drill and fill/ART therapy, whereas in one study, the clinical performance of SMART was found to be better than the conventional ART therapy. Conclusion: SMART and conventional drill and fill/ART techniques have comparable clinical performance for carious primary teeth of children. SMART can be used to treat asymptomatic deep carious lesions as well as apprehensive children. However, the cost-effectiveness of SMART restorations needs to be investigated in a variety of demographics.

An overview of the Canadian landscape on the use of restorative therapies for erectile dysfunction and Peyronie’s disease

Introduction: Restorative therapies (RT(s)), including low-intensity shockwave therapy (Li-SWT) and platelet-rich plasma (PRP), aim to restore natural erectile function. Many clinics offer these therapies for erectile dysfunction (ED) and Peyronie’s disease (PD) with direct-to-consumer (DTC) marketing. This study sought to investigate the landscape of RTs within Canadian clinics. Methods: Online searches were made to identify clinics offering Li-SWT and/or PRP as an RT for treating ED and PD in Canada. Public websites were analyzed, followed by calling clinics for data on cost, treatment protocols, clinic ownership, success rates, and adjunctive therapies. Results: A total of 107 clinics were identified online, with a 68.2% call response rate (n=73). Of the respondents, 56 and 40 clinics provided Li-SWT and PRP therapies, respectively, with 23 clinics offering both. All clinics reported using RTs for ED, with 21 clinics offering Li-SWT and 22 clinics providing PRP for PD. Forty-three clinics provided costs and protocols for Li-SWT, while 33 clinics did so for PRP. The average cost + standard deviation (CAD) of six sessions of Li-SWT was $2167.24+936.11 and one shot of PRP was $1478.68+591.98. Most (60.3%, n=44) clinics reported physician ownership, with a majority (n=28) being family medicine trained. Seven clinics did not provide data and 22 were non-MD-owned. Ten clinics provided success rates, with an average of 87.3%. Conclusions: Despite limited data supporting their routine clinical use, many clinics across Canada offer RTs for ED and PD with varying treatment protocols and increased costs. Further research is required to evaluate the efficacy of RT for ED and PD.

VIRTUAL REALITY BASE REHABILITATION IN STROKE FOR UPPER LIMB MOTOR RECOVERY

Background of the study: The main cause of disability globally is stroke, with upper extremity motor impairment mostly involved. Virtual reality is an emerging technology that has been widely used in stroke rehabilitation with physical therapy for upper extremity functional restoration. The present systematic review is aimed at providing an evidence-based quality assessment of virtual reality based rehabilitation for upper extremity motor recovery in patients with cerebrovascular accident. Methodology: A comprehensive search was conducted in major electronic databases including Medline (PubMed), Pedro, Embase, and CINAHL published articles between 2018 to 2023 whose full text was available. This review comprised 9 studies. With the use of the Cochrane risk of bias tool, the caliber of the included studies was evaluated. Results: The current evidence suggests that VR-based interventions can significantly improve upper limb motor function. The systematic review featured few RCTs and fewer subjects, making generalization difficult, especially as most studies incorporated virtual reality with traditional therapy, and those focusing purely on virtual reality were similarly tiny. The review is the independent creation of authors. Conclusion: VR-based therapies have the potential to be an efficient and secure method for stroke patients to regain upper extremity motor function. To provide standardized procedures and result metrics, as well as to solve the practical difficulties related to implementing VR in stroke therapy, further research is required.

Alzheimer's Disease: Cellular and Pharmacological Aspects.

Alzheimer's disease was described more than 100 years ago and despite the fact that several molecules are being tested for its treatment, which are in phase III trials, the disease continues to progress. The main problem is that these molecules function properly in healthy neurons, while neuronal pathology includes plasma membrane disruption, malfunction of various organelles, and hyperphosphorylation of Tau and amyloid plaques. The main objective of this article is the discussion of a neuronal restoration therapy, where molecules designed for the treatment of Alzheimer's disease would probably be more effective, and the quality of life of people would be better.

Dental Erosion Prevalence and Risk Factor in Hypersensitive Patients.

Dental erosion is common, and patient ignorance is a major issue. Extrinsic and intrinsic factors affect erosion. Some recommend evaluating and treating erosion patients following a brief review of the causes. These involve a comprehensive evaluation of the condition and medical history to identify risk factors for further tooth deterioration. To prevent further degeneration, immediate restorative therapy is needed. A cross-sectional questionnaire was given to Kerala Dental Clinic patients with dentinal hypersensitivity (DH). A total of 5 random clinics from 14 Kerala districts were chosen. At least a total of 1848 of 3500 patients responded. During the COVID-19 epidemic, an online semistructured survey was created using Google Forms to collect data. The current isolation approach discourages large gatherings and face-to-face contact. Google Forms were used to seek informed consent before filling out the questionnaire. Self-administered 20 questions were used to gather information regarding oral hygiene, bad habits, food, and eating disorders, and we inquired whether subjects ate acidic meals and drinks. Most persons with dentine hypersensitivity eat packaged food (70%), pickles (62%), soft drinks (58%), and sweets (56%). Dental erosion is also linked to alcohol consumption (40.4%), teeth clenching (37.4%), mouth breathing (16.4%), and gum chewing (27.5%). Mouthwash-using DH patients (55%) had tooth disintegration.

Decision Tree for Reconstructive Treatment of Peri-implantitis Defects.

Peri-implantitis, a common complication among patients receiving implant-supported restorative therapy, often requires surgical intervention for effective treatment. Understanding the specific configuration of peri-implant bony defect and adjacent bone peaks is crucial for tailoring treatment strategies and improving outcomes. A decision tree for reconstructive peri-implantitis therapy has been developed based on the new classification of defect configurations (Class I to V), guiding clinicians in selecting treatment options, including biomaterials, techniques, and healing approaches. Furthermore, clinicians are encouraged to consider various factors such as local predisposing factors (such as soft tissue characteristics, prosthetic design, and implant position in three-dimensional perspective), clinical factors (surgeon skill and experience), and patient-related factors (such as local and systemic health, preferences, and cost) when evaluating reconstructive therapy options.

Frenectomy management for Ankyloglossia in a 1-Year-old patient under general anesthesia: A case report

Introduction: Ankyloglossia is defined as a congenital disorder that alters tongue mobility and function. It is listed as one of the possible reasons behind breastfeeding issues. The WHO currently recommends mothers to breastfeed exclusively up to 6 months of age, emphasizing the importance of promptly identifying any breastfeeding obstacles and determining the root cause of the problems as the primary focus. The purpose of writing this article is to describe a frenectomy as a surgical procedure that addresses ankyloglossia by excising the lingual frenulum with general anesthesia. Case History: A 1-year-old male patient presented at Dr. Saiful Anwar Regional General Hospital with complaints of difficulty in breastfeeding and consuming complementary foods, as well as prolonged pain experienced by the mother during breastfeeding. The patient had no history of systemic diseases such as heart disease or blood disorders, and there were no known allergies to food or medications. The patient was uncooperative (Frankl scale number 1). After analyzing the ankyloglossia, the choice of frenectomy with general anesthesia was chosen to treat this case. Discussion: Dental examinations and treatments for uncooperative 1-year-old children can be challenging in regular dental offices. Effective behavioral management, such as general anesthesia (GA), is required for safe and efficient treatment. GA involves a multidisciplinary team to oversee the procedure stages, allowing for one-visit treatment, reduced anxiety, and a safer, less painful dental experience. Conclusion: Frenectomy procedure under GA has been performed as an option to facilitate restorative therapy, improve nutritional intake, and quality of life.
