Obstructive sleep apnea (OSA) in children is a common disorder with significant effects on behavior, cognition, and quality of life. Its diagnosis is primarily based on clinical history and examination, supported by standardized questionnaires such as the Sleep-Related Breathing Disorder subscale of the Pediatric Sleep Questionnaire (SRDB-PSQ), which provides high diagnostic accuracy. Although polysomnography remains the gold standard, its use should be limited to high-risk patients or unclear cases due to availability and cost constraints. Adenotonsillar hypertrophy represents the main cause of pediatric OSA and is often self-limiting. For children with mild symptoms, a watchful waiting approach may be appropriate. Randomized controlled trials (e.g., CHAT, POSTA) demonstrate that spontaneous improvement in polysomnographic parameters occurs in some children, though clinical symptoms often persist. Patients with low apnea-hypopnea-index (AHI), mild obesity, and mild symptoms appear suitable for observation but require a close follow-up. Adenotonsillectomy remains the most effective treatment for clinically significant OSA, leading to marked improvements in sleep quality, daytime symptoms, and quality of life, largely independent of polysomnographic findings. Partial tonsillectomy offers similar efficacy with reduced postoperative morbidity. Management should be individualized and focus on clinical presentation more than on sleep recordings. Future research should focus on identifying which children benefit most from conservative or surgical strategies. Full article

Background and Objectives: Chronic knee pain (cKP) affects approximately 25% of adults worldwide, with prevalence increasing over recent decades. While conventional treatments have clinical limitations, several types of electrical stimulation have been suggested to improve patients’ quality of life. The electrical stimulation literature contains inadequate patient-reported outcome measures (PROMs) data. Encouraging preliminary H-Wave^® device PROMs results for chronic neck, shoulder, and low back pain have previously been published. This PROMs study’s goal is to similarly assess the efficacy of H-Wave^® device stimulation (HWDS) in patients with differing knee disorders. Materials and Methods: This is an independent, retrospective, observational cohort study analyzing H-Wave^® PROMs data, prospectively and sequentially collected over 4 years. In total, 34,192 pain management patient final surveys were screened for participants who were at least 18 years old, used H-Wave^® for any knee-related disorder, reporting chronic pain from 90 to 730 days, with device treatment duration from 22 to 365 days. PROMs included effects on function, pain, sleep quality, need for medications, ability to work, and patient satisfaction; additional data includes gender, age (when injured), chronicity of pain, prior treatments, and frequency and length of device use. Results: PROMs surveys from 34,192 HWDS patients included 1143 with “all knee”, 985 “knee injury”, and 124 “knee degeneration” diagnoses. Reported improvements in function/ADL (96.51%) and work performance (84.63%) were significant (p < 0.0001), with ≥20% pain relief in 86.76% (p < 0.0001), improving 2.96 points (average 0–10 NRS). Medication use decreased (69.85%, p = 0.0008), while sleep improved (55.33%) in knee injury patients. Patient satisfaction measures exceeded 96% (p < 0.0001). Subgroup analysis suggests that longer device use and shorter pain chronicity resulted in increased (p < 0.0001) HWDS benefits. Conclusions: HWDS PROMs data analysis demonstrated similarly encouraging outcomes for cKP patients, as previously reported for several other body regions. Knee injury and degeneration subgroups had near-equivalent benefits, as observed for all knee conditions. Despite many reported methodological limitations, which limit causal inference and preclude broader recommendations, HWDS appears to potentially offer several benefits for refractory cKP patients, requiring further studies.

Older individuals primarily belong to the group with an increased risk of SARS-CoV-2 infection. Social distancing and other strategies to mitigate the COVID-19 pandemic may negatively impact the psychophysical parameters of seniors. Objective: The main aim of this study is to analyze the changes in psychophysical parameters among seniors in the context of the COVID-19 pandemic over a one-year observation. Materials and methods: The observation involved 54 respondents aged 60 and above. The study was conducted three times from March 2020 to April 2021. The selected research method was a diagnostic survey based on a questionnaire. Results: The level of general physical activity in the study groups during the pandemic was determined to be moderate with an upward trend. A downward trend in self-assessment of quality of life was observed, particularly in the area of mental health, along with an increase in symptoms of anxiety, aggression, and insomnia. Conclusions: The pandemic period did not significantly affect the level of physical activity among the surveyed seniors, but an intensification of mental symptoms was noticeable. Full article

Background/Objectives: Sleep disorders represent a significant health burden among children and adolescents with autism spectrum disorder (ASD), affecting their core symptoms, behavior, and quality of life. While physical activity has shown promise in managing sleep disorders in the general pediatric population, its effectiveness for children and adolescents with ASD remains understudied. Methods: This retrospective cohort study analyzed electronic health records from 132 healthcare organizations, examining 155,860,529 individuals to determine sleep disorder prevalence in ASD populations and evaluate the impact of physical activity interventions. We identified 248,940 children and adolescents with ASD aged 5–18 years, of whom 38,976 had documented sleep disorders. Propensity score matching was performed to compare patients with ASD and sleep disorders who received physical activity interventions with matched controls. Primary outcomes included sleep disorder resolution and medication utilization changes at 1- and 5-year follow-up. Bonferroni correction was applied to secondary analyses to account for multiple comparisons. Results: The prevalence of sleep disorders was markedly higher in children and adolescents with ASD (19.25%) compared to non-ASD peers (3.37%), with risk ratios escalating from childhood (RR = 5.34, 95% CI: 5.28–5.40) to adolescence (RR = 6.12, 95% CI: 6.05–6.19). After matching, 3709 patients were included in each group. Physical activity interventions were associated with significantly higher sleep disorder resolution at 1 year (−59.9% vs. −5.05%, p = 0.001) and sustained benefit at 5 years (−49.83% vs. +7.26%, p = 0.001). After Bonferroni correction, improvement in sleep apnea at 1 year remained statistically significant (−62.26% vs. +9.39%, Bonferroni-adjusted p = 0.040). Improvements in parasomnia and insomnia did not survive correction and were considered exploratory. Age emerged as a key effect modifier: adolescents (12–18 years) demonstrated sustained improvements in overall sleep outcomes at both 1- and 5-year follow-up that met Bonferroni-corrected thresholds, whereas younger children (5–11 years) showed limited and inconsistent responses. Among comorbidity groups, anxiety-comorbid patients exhibited the strongest overall improvement (−58.7% vs. −12.4%, p < 0.01), while reductions in amphetamine use and changes in melatonin prescribing patterns should be interpreted as exploratory findings requiring prospective confirmation. Conclusions: This large-scale observational study suggests structured physical activity interventions are associated with sustained improvements in overall sleep disorders among children and adolescents with ASD. While subtype- and subgroup-specific associations were observed, many attenuate after multiple comparison adjustments, highlighting the need for cautious interpretation. Findings support exploring physical activity in comprehensive care plans, with prospective randomized trials needed to confirm causality, optimize protocols, and address multiplicity. Full article

Sensory processing differences, reported in up to 97% of individuals with autism spectrum disorder (ASD), are increasingly recognized as a defining feature of the condition, shaping perception, cognition, and adaptive behavior. Atypical sensory responsivity, ranging from hyper- to hypo-reactivity and sensory seeking, emerges early in development and contributes to the clinical and neurobiological heterogeneity of autism. Alterations in neural connectivity, the balance of excitation and inhibition, and multisensory integration are thought to underlie these sensory profiles, influencing emotional regulation, attention, and social interaction. Sensory features also interact with co-occurring conditions such as anxiety, attention deficit hyperactivity disorder, and sleep and feeding difficulties, thereby shaping developmental trajectories and influencing adaptive behavior. Clinically, these sensory dysfunctions have a significant impact on daily participation and quality of life, extending their effects to family functioning. Understanding individual sensory phenotypes is therefore essential for accurate assessment and personalized intervention. Current therapeutic approaches include Sensory Integration Therapy, Sensory-Based Interventions, Sequential Oral Sensory Approach, and structured physical activity programs, often complemented by behavioral and mindfulness-based techniques. Emerging neuroplasticity-oriented methods for targeted modulation of sensory processing networks include neurofeedback and non-invasive brain stimulation. Overall, current evidence highlights the central role of sensory processing in ASD and underscores the need for multidisciplinary, individualized approaches to optimize developmental trajectories and enhance adaptive functioning. This review provides an updated synthesis of sensory processing in ASD, integrating neurobiological, developmental, and clinical evidence to highlight established knowledge, unresolved questions, and priorities for future research.

Background/Objectives: Obstructive sleep apnea (OSA) is a prevalent sleep-related breathing disorder characterized by repeated episodes of upper airway obstruction during sleep, leading to intermittent hypoxia and fragmented sleep architecture. Orofacial myofunctional therapy (OMT) has emerged as a promising non-invasive approach to improving airway patency in individuals with mild-to-moderate OSA. However, the role of sleep ergonomics—including sleep posture and pillow support—in enhancing OMT outcomes remains underexplored. This study aimed to evaluate whether ergonomic interventions could augment the therapeutic effects of OMT in adult patients with mild-to-moderate OSA. Methods: A 12-week prospective cohort study was conducted involving 60 adult participants diagnosed with mild-to-moderate OSA. All participants underwent a structured orofacial myofunctional therapy (OMT) program comprising exercises for tongue elevation, lip seal enhancement, and soft palate strengthening. In addition, ergonomic instructions were provided regarding optimal sleeping posture and pillow adjustment. Compliance with ergonomic practices was monitored weekly using infrared night-vision cameras and reviewed by a blinded sleep technician. Pre- and post-intervention assessments included apnea–hypopnea index (AHI), Pittsburgh Sleep Quality Index (PSQI), and Ep-worth Sleepiness Scale (ESS). Results: Statistically significant improvements were observed in all measured parameters following the intervention. AHI scores reduced from 18.2 ± 4.5 to 10.6 ± 3.9 events/hour (p < 0.001), PSQI scores improved from 11.3 ± 2.1 to 6.5 ± 1.8 (p < 0.001), and ESS scores declined from 13.7 ± 2.6 to 7.4 ± 2.0 (p < 0.001). Participants with high adherence to ergonomic recommendations demonstrated significantly greater clinical improvements compared to less adherent individuals. Conclusions: The combination of ergonomic sleep posture interventions with OMT was associated with positive improvements in sleep-related outcomes, comparable to or in some cases better than those reported in previous studies evaluating these interventions independently. As an observational cohort without a control arm, this study cannot establish causality but provides preliminary evidence to guide the design of future randomized clinical trials. Full article

Background: Sleep disorders are common in childhood and adolescence and can negatively affect cognitive development, mood regulation, behaviour, and quality of life. Parents frequently seek complementary therapies such as homoeopathy, yet the scientific evidence for homoeopathic treatments in paediatric sleep disorders remains uncertain. This systematic review examines the effectiveness of homoeopathic interventions for sleep disorders in children and adolescents according to evidence-based medicine principles. Objectives: To systematically review and evaluate the effectiveness of homoeopathic treatments for sleep disorders in children and adolescents, following evidence-based principles. We aimed to summarise current clinical evidence from 2015–2025 on whether homoeopathy improves paediatric insomnia and other sleep-related disorders and to assess the quality of that evidence. Methods: PubMed, Scopus, and allied databases were searched for RCTs and observational studies involving participants <18 years with sleep disorders (insomnia, bruxism, and enuresis) treated with homoeopathy. English-language studies were screened manually, and bias was assessed qualitatively. Results: Five studies (four RCTs, one observational; 451 participants) met inclusion criteria: Two RCTs reported complex homoeopathic remedies showing some improvement over glycine or placebo for insomnia symptoms. A crossover RCT reported nearly significant bruxism improvement with Melissa officinalis 12C versus placebo (Visual Analogic Scale 0–10; ΔVAS −2.36 vs. −1.72, p = 0.05) and significant VAS improvement in comparison to Phytolacca (p = 0.018). A double-blind RCT in enuretic children showed individualised homoeopathy reduced weekly bedwetting episodes (median −2.4 nights, p < 0.04). One observational study also noted symptom improvement of nocturnal enuresis. No serious adverse effects were reported. Bias risk varied: one open-label trial showed high risk; others were adequately blinded. Conclusions: Current evidence suggests preliminary signals that homoeopathy may have modest benefits for paediatric insomnia, bruxism, and enuresis, with an acceptable safety profile. However, the number and quality of studies are limited, and findings should be interpreted cautiously. Larger, high-quality trials are needed to clarify the potential role of homoeopathic interventions in paediatric sleep disorders. Current epistemological advances in study planning and medical student training should be taken into account: critical and intersectional (or better still, transdisciplinary) thinking with retrospective examination of heuristic initial theses, gender aspects, life course health, context variables and criteria for individualised, patient-related precision medicine.

Background: Orofacial myofunctional therapy (OMT) is an emerging adjunctive treatment for obstructive sleep apnea (OSA), but its effects on upper airway structural support, particularly the hyoid complex, are not well defined. This study assessed the short-term effects of OMT on hyoid bone position and sleep-related indices in adults with mild to moderate OSA. Methods: In this assessor-blinded randomized controlled trial (ClinicalTrials.gov Identifier: NCT06079073), 13 adults with mild to moderate OSA were randomized to a 12-week web-based OMT program (n = 9) or a waitlist control group (n = 4). Cone-beam computed tomography (CBCT) and three-night home sleep testing were performed at baseline and follow-up. The primary outcome was change in axis-based cephalometric hyoid position measures; secondary outcomes included sleep parameters such as the apnea–hypopnea index (AHI). Results: No significant within- or between-group differences were observed in AHI, oxygen desaturation index, or mean nocturnal SpO₂ after 12 weeks (all p > 0.05). However, several cephalometric variables showed significant between-group differences. The waitlist group exhibited greater posterior–inferior hyoid displacement than the OMT group, with large effect sizes across multiple vector measures (all p ≤ 0.045; r = 0.56–0.66). Posterior and inferior hyoid displacement was associated with higher AHI and lower SpO₂, whereas increased lower pharyngeal airway width was associated with lower AHI. Conclusions: Short-term OMT did not improve sleep-disordered breathing indices but was associated with stabilization of hyoid bone position. These findings suggest that structural stabilization may precede functional improvement and highlight the clinical relevance of vector-based hyoid analysis. Full article

Prader–Willi syndrome (PWS) is a rare, multisymptomatic genetic disorder caused by the absence or dysfunction of specific genes on chromosome 15. The genetic abnormality is anticipated to cause a dysfunction of the hypothalamus, which is also central in the regulation of the autonomic nervous system (ANS). Typical symptoms of PWS indicating a hypothalamic dysfunction include muscular hypotonia, poor growth, short stature, and feeding difficulties in infancy, which in early childhood are replaced by hyperphagia, leading to a high risk of obesity. Other characteristics, such as sleep difficulties, altered pain perception, delayed gastric emptying and constipation, blood pressure irregularities and dysregulated stress response, altered temperature regulation, delayed pupillary reaction, and urine retention and incontinence, all indicate a dysfunction of ANS. The ANS is usually divided into three parts: the sympathetic nervous system (SNS), which activates the fight-or-flight response during stress; the parasympathetic nervous system (PNS), which promotes calm and digestion; and the independent enteric nervous system (ENS), which regulates the gastrointestinal tract. Noradrenaline is the main neurotransmitter for the SNS, and acetylcholine for the PNS, while the ENS is regulated mainly by acetylcholine and serotonin. However, the ENS is modulated by both the SNS and the PNS, as well as many neuropeptides. Peptides regulating behavior, metabolism, appetite, and satiety have been extensively studied in PWS. However, studies of the role of neuropeptides in regulating other autonomic functions are limited and remain poorly understood. This review aims to synthesize current evidence from both animal models and human studies to explore potential mechanisms by which neuropeptides may contribute to autonomic dysfunction in individuals with PWS.

Dental caries is a prevalent childhood disease with a multifactorial etiology. The aim of the study is to evaluate the prevalence of extensive dental caries and its association with socioeconomic factors, dietary and daily toothbrushing frequency, and sleep disorders (SDs) in children aged 6 to 10 years. A cross-sectional study with 516 children and their caregivers was carried out. Socioeconomic information and data on dietary habits and oral health behaviors were obtained through a questionnaire administered to parents/caregivers. SDs were assessed using the Sleep Disturbance Scale for Children. Extensive dental caries was assessed using the ICDAS II (codes 5–6). Descriptive analyses and multivariate Poisson regression were performed. The prevalence of extensive dental caries was 20.7%. Extensive caries was associated with lower parental education (PR = 1.68; 95% CI: 1.16–2.44; p = 0.006), household income (PR = 5.64; 95% CI: 1.67–18.99; p = 0.005), frequent consumption of sugary snacks/drinks (PR = 2.74; 95% CI: 1.97–3.83; p < 0.001), and greater severity of SD (PR = 1.02; 95% CI: 1.00–1.03; p = 0.007). Extensive dental caries lesions are more common in children whose parents/caregivers have lower levels of education and income, consume more sugary foods/drinks, and have SDs. Full article

Obstructive sleep apnea syndrome (OSAS) is a common disorder with established cardiovascular and metabolic risks. Positive airway pressure (PAP) therapy remains the standard of care; however, its long-term effectiveness is often limited by poor compliance and adherence. This study sought to explore clinical and device-related factors influencing PAP use, with emphasis on pressure variability in Auto-PAP users and comorbidities such as COPD. We performed a retrospective analysis of 359 patients with OSAS who were treated with CPAP, Auto-PAP, or BiPAP devices at the Marius Nasta Institute of Pneumology between January 2022 and July 2024. Compliance was measured as the proportion of days the device was used, whereas adherence was estimated through average nightly hours of use. Patient data were stratified by demographic, clinical, and device-related characteristics. Statistical testing included Chi-square, Wilcoxon rank-sum, and correlation analyses. Demographics did not significantly differ between compliant and non-compliant groups. Notably, Auto-PAP users with greater pressure variability (>10 cm H₂O) had significantly lower compliance (p = 0.001). Nasal mask preference was also associated with poorer compliance (p = 0.030). Multivariate models further revealed that atrial fibrillation reduced the likelihood of good adherence (OR = 0.319, 95% CI 0.137–0.746). These results highlight the importance of monitoring pressure variability, device type, and comorbidities to personalize PAP therapy and improve long-term outcomes. Full article

Background: Obstructive sleep apnea (OSA) is a heterogeneous disorder associated with substantial cardiometabolic and neurocognitive morbidity. Although the apnea–hypopnea index (AHI) remains the conventional measure of OSA severity, it only partially reflects the underlying pathophysiological complexity. Growing evidence indicates that nocturnal hypoxemia may be a more powerful marker of adverse outcomes than event frequency alone. Therefore, this study aimed to identify distinct OSA phenotypes based on oximetry-derived features and to assess whether these profiles offer additional clinical insight beyond traditional AHI-based classification. Methods: This multicenter retrospective study, part of the Living with OSA and CPAP: The Apulia Region Experience project, included 1386 adults diagnosed with OSA across 15 sleep centers in Southern Italy. Standardized clinical, anthropometric, and polysomnographic (PSG) data were collected. Hierarchical clustering analysis was performed based on PSG oximetry-derived variables. Resulting clusters were compared across demographic, clinical, hypoxemic, and therapeutic features. Results: Three reproducible clusters emerged. Cluster 1 (mild–non-obese) included younger, leaner patients with lower AHI (22.9 ± 10.5 events·h⁻¹), minimal desaturation (T90 5.6 ± 7.6%), and limited comorbidities. Cluster 2 (severe–obese–hypoxemic) represented the most critical phenotype, characterized by marked obesity (BMI 39.2 ± 8.2 kg·m⁻²), severe OSA (AHI 74.9 ± 17.9 events·h⁻¹), profound nocturnal hypoxemia (T90 51.5 ± 28.2%), and a high prevalence of metabolic disorders (76%), requiring higher CPAP pressures and frequent oxygen supplementation. Cluster 3 (older–comorbid) comprised older males (63.7 ± 11.8 years) with moderate-to-severe OSA (AHI 44.8 ± 15.2 events·h⁻¹) and multiple cardiometabolic comorbidities. Conclusions: Oximetry-derived variables identify distinct and clinically meaningful OSA phenotypes that extend beyond traditional AHI-based classification. Recognizing hypoxemia-driven subtypes could improve risk stratification and enable more personalized management strategies in clinical practice. Full article

Background: Menopause, a critical period during a woman’s life, is characterized by various changes, including disturbances in their oxidative balance and circadian rhythm. Currently, the gut microbiome is suggested as an important participant in these processes. Methods: This study involved 96 menopausal women. Their sleep quality was assessed using three questionnaires: the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). The GSH and GSTP1 contents in the serum were measured by means of immunoassay methods, while the composition of the gut microbiome was determined via molecular genetic methods. Results: E. coli, K. oxytoca, S. aureus, Enterobacter spp., Shigella spp., Streptococcus spp., Prevotella spp., and M. stadmanae were found to correlate with the GSH content in different sleep groups, while the presence of K. oxytoca, S. aureus, Enterococcus spp., K. pneumoniae, and M. stadmanae is also important for the GSH level in several of these groups. F. prausnitzii, S. aureus, P. micra, Acinetobacter spp., and E. rectale are associated with GSTP1 concentration in various sleep groups, while the presence of F. nucleatum and P. micra is also relevant for the GSTP1 content in some of these groups. Conclusions: Thus, in menopausal women, the composition and structure of the gut microbiota are associated with sleep disorders. GSH and GSTP1 are associated with some gut microbiome markers in menopausal women, but these relationships differ in different sleep disorders. Full article

REM sleep behavior disorder (RBD) represents a prodromal manifestation of Parkinson’s disease (PD), reflecting the breakdown of inhibitory networks extending from the brainstem to the cortex. This review synthesizes pathological, physiological, and behavioral evidence to illustrate how early α-synuclein pathology disrupts REM-sleep atonia and motor automaticity through degeneration of pontomedullary and cholinergic–inhibitory circuits. The resulting failure of inhibitory precision links nocturnal REM sleep without atonia to daytime gait and postural abnormalities, framing RBD as a dynamic systems disorder rather than a purely sleep-related phenomenon. By examining this continuum across neurophysiological, behavioral, and clinical domains, the review highlights current knowledge gaps, particularly regarding the temporal dynamics of degeneration and compensation. It further integrates multimodal biomarkers that capture these transitions in vivo and discusses therapeutic strategies aimed at preserving inhibitory network integrity and delaying phenoconversion to overt Parkinsonian syndromes.
