• 39 Safety, feasibility, child, and parent perceptions following biofeedback and breathing practices in children with attention deficit hyperactivity disorder: The healing minds study

  Journal of Clinical and Translational Science · 2026-04-01

  articleOpen accessSenior author

  Objectives/Goals: Attention deficit hyperactivity disorder (ADHD) affects 5.9% of youth worldwide and is associated with mental health disorders. In adults, HeartMath biofeedback improves ADHD, emotional regulation, and anxiety. Breathing practices promote similar outcomes. Our goal was to examine the synergistic effect of these therapies in children with ADHD. Methods/Study Population: A 10-week, 2-arm randomized controlled clinical trial was conducted in a rural health care clinic to examine the safety, feasibility, preliminary efficacy, and self-reported child and parent perceptions of a biofeedback plus breathing practices intervention (Healing Minds) in a pediatric population (n=12; M=5; F=7; 11.6 ±3.6 years). Children were randomized to waiting list placebo (P) or treatment (T) intervention [Weekly biofeedback (HeartMath) and breathing exercises (Qi gong, belly, box, and alternate nostril) by trained medical staff]. Symptoms and severity of ADHD (Vanderbilt; Conners), Screen for Child Anxiety-Related Disorders, Child & Adolescent Trauma Screen (CATS), CATS-Caregiver, Child & Youth Resilience Measure, and perceptions by interview were assessed at baseline, 5 and 11 weeks. Results/Anticipated Results: Twelve children were enrolled (6=T; 6=P) into the clinical trial. Nine completed the study [T (N=4); P (N=5)]. One moderate, unrelated adverse event was reported. Treatment attendance rates varied [90% (2), 70% (1), 60% (1), and 30% (1)]. Children self-reported reduced panic attacks, improved sleep, and feelings of self-control. Parents perceived a calmer home with fewer meltdowns, less overwhelming events, and expressed satisfaction with biofeedback, Qi gong, and belly breathing, but not box and alternate nostril breathing. Questionnaires were perceived as burdensome, and placebo waiting list delays were unacceptable to parents. School-related scheduling challenges and missing assessment data limited study implementation. Small sample sizes limited statistical power and the evaluation of outcomes. Discussion/Significance of Impact: Healing Minds shows promise as a beneficial adjunct to clinical care in rural children with ADHD. The program was shown to be safe and feasible. Children and parents self-reported beneficial effects. Future studies should include a patient-centered study design, focused breathing techniques, fewer assessments, and improved school coordination.

• CardioMEMS device impact on heart failure hospitalization rates: A pre- and post-implantation analysis

  World Journal of Biology Pharmacy and Health Sciences · 2025-06-23

  articleOpen access

  Introduction : The CardioMEMS HF System proactively manages heart failure by addressing hemodynamic congestion before overt symptoms appear. This device provides daily pulmonary artery pressure readings, enabling tailored medical therapy. This study investigates CardioMEMS' impact on heart failure hospitalization rates in a community hospital setting. Methods: A retrospective analysis was conducted on 58 heart failure patients who underwent CardioMEMS implantation. Heart failure-related hospitalization rates were compared one year before and after implantation using electronic health records and paired t-tests. Results: A statistically significant reduction in heart failure hospitalization rates was observed following CardioMEMS implantation (t-statistic: 3.7540265, p-value: 0.0004156). The average number of heart failure-related hospitalizations per patient per year decreased by 0.67. Discussion: The findings align with previous studies demonstrating the device's efficacy in proactively managing hemodynamic congestion and preventing hospitalizations. Remote monitoring technologies, like CardioMEMS, facilitate communication between physicians and patients, encouraging active participation. Integrating CardioMEMS into heart failure management programs optimizes its capabilities and promotes timely interventions. Conclusion: CardioMEMS is associated with a significant reduction in heart failure hospitalization rates in a community hospital, improving patient outcomes and community health.

• Efficacy of Oral Itraconazole Monotherapy in Pediatric Superficial Dermatophytosis: A Prospective Study from a Tertiary Care Center

  Indian Journal of Paediatric Dermatology · 2025-07-01

  articleOpen accessSenior author

  Introduction: Superficial dermatophytosis has seen a sharp rise in the recent years across India, becoming more widespread and difficult to manage. This concerning trend is now increasingly evident in children, and hence, the need to evaluate the effectiveness of systemic therapies like itraconazole in the pediatric population. Materials and Methods: This was a prospective, interventional study conducted for 1 year. Detailed history, clinical examination, direct microscopy, and polymerase chain reaction testing for species identification were performed in all patients. Eligible children were treated with oral itraconazole solution at a dosage of 5 mg/kg/day for 4 weeks. The treatment outcome was assessed based on the change in clinical composite score from baseline to 4 weeks, and adverse effects, if any, were noted. Results: A total of 53 patients were included in the study. The highest prevalence was seen in the age group of 1–5 years, and a male predominance was seen. Tinea corporis and tinea cruris were the most common clinical types, and Trichophyton interdigitale was the most frequently isolated species. Oral itraconazole showed good efficacy with 92.4% of patients achieving significant clinical improvement by the end of 4 weeks. Adverse effects were minimal and self-limiting. Conclusion: Oral itraconazole demonstrated excellent clinical response with good tolerability in children and may be considered a safe and effective treatment option in moderate-to-severe paediatric superficial dermatophytosis.

• “Cilioretinal artery occlusion: Current scenario”

  European Journal of Ophthalmology · 2025-05-27

  review

  IntroductionAbout 5% of retinal artery occlusions are cilioretinal artery occlusions (CLRAO). It was found to be mostly unilateral (70.30% to 93.65%) and temporal in location (80.77% to 100%).EtiopathogenesisRisk factors for CLRAO include emboli from various atheromas, vasculitis, collagen vascular disorders, hypertensive vascular changes, hemoglobinopathies, hypercholesterolemia, hypercoagulable conditions, arrhythmias, migraine etc.Clinical presentationCilioretinal artery occlusion may present in three different scenarios: i) Isolated ii) with central retinal vein occlusion (CRVO) iii) in combination with Ischemic optic neuropathy.Imaging featuresFFA shows slow filling of cilioretinal artery. SD OCT may reveal hyperreflectivity of inner retinal layers. OCTA will show non perfusion of CLRA along with compromised perfusion of superficial and deep retinal capillary plexus and hyper reflective inner retinal layers. Perimetry shows paracentral scotoma which may be persistent in many cases. Association of paracentral acute middle maculopathy (PAMM) with isolated CLRAO causing paracentral scotomas, has been reported. Type 1 PAMM lesions affect layers above outer plexiform layer (OPL) and Type 2 PAMM involve layers below OPL.ManagementTime period for active intervention is between 4.5 to 12 h. Meta-analysis reports suggest administration of thrombolytic agents before 4.5 h for better outcome. Hyperbaric oxygen (HBO) therapy is another modality. Reduction of intraocular pressure need to be achieved. Methyl prednisolone is advisable in CLRAO associated with Giant cell arteritis and other vasculitis. American Heart Association suggests administration of intravenous or intraarterial tissue Plasminogen Activator (tPA) as a viable option.ConclusionCLRAO and its management still has the potential for further research and trials.

• Development of an artificial intelligence powered software for automated analysis of skeletal muscle ultrasonography

  Scientific Reports · 2025-04-28 · 7 citations

  articleOpen access

  Muscle ultrasound has high utility in clinical practice and research; however, the main challenges are the training and time required for manual analysis to achieve objective quantification of muscle size and quality. We aimed to develop and validate a software tool powered by artificial intelligence (AI) by measuring its consistency and comparability of expert manual analysis quantifying lower limb muscle ultrasound images. Quadriceps complex (QC) and tibialis anterior (TA) muscle images of healthy, intensive care unit, and/or lung cancer participants were captured with portable devices. Manual analyses of muscle size and quality were performed by experienced physiotherapists taking approximately 24 h to analyze all 180 images, while automated analyses were performed using a custom-built deep-learning model (MyoVision-US), taking 247 s (saving time = 99.8%). Consistency between the manual and automated analyses was good to excellent for all QC (ICC = 0.85–0.99) and TA (ICC = 0.93–0.99) measurements, even for critically ill (ICC = 0.91–0.98) and lung cancer (ICC = 0.85–0.99) images. The comparability of MyoVision-US was moderate to strong for QC (adj. R2 = 0.56–0.94) and TA parameters (adj. R2 = 0.81–0.97). The application of AI automating lower limb muscle ultrasound analyses showed excellent consistency and strong comparability compared with human analysis across healthy, acute, and chronic population.

• 516 Follicle-stimulating hormone is reduced following a novel nutritional therapeutic in postmenopausal women with obesity

  Journal of Clinical and Translational Science · 2025-03-25

  articleOpen accessSenior author

  Objectives/Goals: Increased follicle-stimulating hormone (FSH) is linked to declines in ovarian and metabolic function in older women. Obesity is both a manifestation and a driver of aging pathologies. In animal models, FSH and insulin resistance (IR) were reduced after 6 mos. of a nutritional therapeutic (GLYLO). Our goal was to translate preclinical evidence to humans. Methods/Study Population: An integrated, precision medicine approach identified a unique phenotype of aging-related debility relative to older females. A non-comparer pilot study was conducted to translate GLYLO preclinical findings to postmenopausal women with obesity (n = 85; >55 years; body mass index [BMI] = 35.0±4.35; range: 30.3–42.8). Participants meeting the inclusion and exclusion criteria (n = 13) were enrolled and received two capsules of GLYLO (vitamins and natural products) daily for 6 mos. Assessments for FSH, estradiol (E2), IR (homeostatic model [HOMA-IR]), total cholesterol (TC), low- (LDL), high-density lipoproteins (HDL), safety biomarkers (e.g., red cell distribution width [RDW%], mean corpuscular volume [MCV]), and depression (Center for Epidemiologic Studies Depression Scale) were conducted prior to and after 6 mos. Results/Anticipated Results: Mixed-effect models with intent-to-treat analysis were applied to compare outcomes prior to (n = 13) and following (n = 7) the intervention. Significant reductions in FSH were observed (-13.1 [2.47] ∆/SD; p = 0.002)) following the 6-month intervention. Interestingly, BMI, E2 (p = 0.412), HOMA-IR (p = 0.885), TC (p = 0.363), and LDL (p = 0.145) were unchanged, while HDL decreased significantly (-9.7 [3.82] ∆/SD; p = 0.044). Other biomarkers, RDW% (-0.2 [0.05] ∆/SD; p = 0.009) and MCV (-2.3 [0.33] ∆/SD; p = 0004), were significantly reduced. All other safety parameters were not altered. Six participants reported mild to moderate adverse events (acid indigestion) and were lost to follow-up. Depression scores significantly increased (+4.0 [0.75] ∆/SD; p = 0.002)). Results were similar with and without intent to treat analysis. Discussion/Significance of Impact: Decreased FSH, but not IR, was observed following six months of GLYLO in postmenopausal women with obesity. Significant alterations in HDL, depression, RDW%, and MCV warrant further investigation. Findings are limited by the small sample size and loss to follow-up. Randomized, controlled trials are needed to confirm these results.

• Safety and Preliminary Effectiveness of a Natural, Multi-modal Therapeutic in Postmenopausal Women with Obesity

  medRxiv · 2025-09-07

  preprintOpen accessSenior author

  Abstract Introduction Postmenopausal women exhibit increased central obesity due to aging-related alterations in hormones leading to adverse metabolic and biological consequences. The present study aimed to evaluate the safety of a natural, multi-modal therapeutic and observe alterations in metabolic and aging-related outcomes in humans for the first time. Methods A non-comparer pilot study was conducted to translate preclinical findings of a glycation-lowering supplement (Alpha-lipoic acid, nicotinamide, thiamine, piperine, pyridoxamine) to postmenopausal women with obesity [n=85; >55 years; BMI=35.0±4.35/30.3–42.8 (Figure 1)]. Qualified participants (n=13) consumed two capsules daily for 6 months. Complete Blood Count [e.g. (Red Cell Distribution Width (RDW%)], Mean Corpuscular Volume (MCH), etc.], depression (Center for Epidemiologic Studies Depression Scale), insulin resistance [Homeostatic Model (HOMA-IR)], fat oxidation [respiratory quotient (RQ)], weight/height, waist circumference (WC), bone mineral density (BMD) by Dual-Energy X-ray Absorptiometry, low (LDL) and high density (HDL) lipoproteins, phenotypic age (PA), follicle stimulating hormone (FSH) caloric intake [(CI)-NIH/NIS/ASA 24-2020 Dietary Assessment], and immediate recall [(IM) BrainCheck] were assessed at baseline and 6-month-follow-up. Results No serious adverse events were reported. Six participants reporting mild/moderate adverse events were lost to follow-up. Mixed-effect models (intent-to-treat analysis) compared outcomes prior to (n=13) and following (n=7) the 6-month intervention. RDW% (p=0.009), MCV (p=0004), RQ (p=0.02), WC (p=0.02), HDL (p=0.044), phenotypic age (p=0.037), FSH (0.002), and CI (p=0.01) significantly decreased. Depression (p=0.002), height (p=0.003), BMD (p=0.02) and IM (p=0.04) significantly increased; HOMA-IR and LDL were unchanged. Conclusions Preliminary results indicate that a natural, multi-modal therapeutic is safe in postmenopausal women with obesity. Several metabolic and aging-related outcomes improved following the intervention. However, decreased HDL, RDW%, MCV and increased depression warrant further investigation in future randomized-controlled trials. Clinicaltrials.gov # NCT06242535
