A previously defined tissue matrix damage score was used to quantify the extent of fracturing and cracking in the matrix. The cell death (PCD) was counted and presented as a percentage against all cells live plus dead. The energy absorbed was 36.5% higher in G1 than in G0 (p = 0.034). However, the damage score and PCD of samples in the G1 group was much larger than the G0 group, ~300% and 161% respectively. Microscopy showed that cell death is associated to both matrix compaction and further fibrillar destructuring from the ECM to the territorial matrix regions of the chondron. Following impact loading, cartilage tissue that appears normal but contains sub-micron fibrillar matrix destructuring responds with significantly increased cell death.

Obstructive sleep apnea (OSA) is a common sleep disorder, which causes wide range of neurological and psychiatric symptoms. Several studies demonstrated structural and functional brain alterations using magnetic resonance imaging (MRI) techniques. Recently, diffusion-based brain MRI studies in patients with OSA showed changes in diffusion measures that represent various impairments of white matter (WM) integrity. The various finding may be due to diffusion indices employed for detection of neural impairment at the microstructural level, phase of the disease and the goals of studies.

We aimed to identify a common abnormal WM pattern across the previous studies.

We reviewed related literature in EMBASE, Scopus and PubMed databases and identified 13 studies that meet our selection criteria.

The current data pointed to WM integrity changes in corpus callosum, cingulate cortex, corticospinal tract, insular cortex, basal ganglia, and limbic sites. These regions mainly contribute in mood, autonomic and cardiovascular regulation.

Widespread use of diffusion magnetic resonance imaging (dMRI) parameters provides insight into the pathophysiology of OSA, stage of the disease and planning appropriate treatments in future.

Pediatric obesity and sleep-disordered breathing (SDB) are strongly associated, and both promote metabolic impairments. Choline However, the effects of a lifestyle intervention on the overall metabolic syndrome (MetS) are unknown. The objectives were i) to evaluate the effects of a lifestyle intervention on cardiometabolic risk (CMR), assessed with a dichotomous (MetS) and a continuous (MetScore

) instrument, in obese adolescents with and without SDB and ii) to compare the post-intervention cardiometabolic responses between adolescents with persistent (apnea-hypopnea index; AHI≥2) or normalized-SDB (AHI<2).

Seventy-six adolescents with obesity recruited from two specialized institutions underwent a 9-12month diet and exercise intervention. Sleep and SDB (AHI≥2) were studied by polysomnography. Anthropometric parameters, fat mass (FM), glucose, insulin, lipid and leptin profiles, blood pressure (BP), MetScore

and MetS were assessed pre- and post-intervention. We performed comparisons between Non-SDB and SDB ctive in decreasing the CMR whether or not SDB was normalized in obese adolescents.

Sleep-related breathing disorders (SRBD) not only adversely impact cardiovascular and pulmonary functions but also reduce the quality of life. This study attempted to investigate the severity and related factors of SRBD among human immunodeficiency virus (HIV)-infected people with sleep complaints.

A cross-sectional study was conducted among HIV-infected people with Pittsburgh Sleep Quality Index (PSQI) values above 5 points. SRBDs were defined as Apnea-Hypopnea Index (AHI) over 5 events/hour by full channel home-based polysomnography (PSG). An AHI greater than 30 was categorized as moderate to severe apnea. All of the participants were asked to rate the severity of their snoring, complete a snore outcomes survey (SOS) and complete the PSQI. Multiple logistic regression analysis was conducted to examine the associated factors of severity of SRBD among HIV-infected people.

Of 54 male HIV-positive patients with sleep complaints, 34 subjects (62.96%) were diagnosed with SRBDs, and 29.63% were categorized as having moderate to severe SRBD. SOS score was significantly associated with HIV patients with moderate to severe SRBD (adjusted odds ratio=0.93, 95% CI 0.87-1.00, p=0.045).

SRBDs is highly prevalent in male HIV-infected people with sleep complaints. Intensive snoring was one of the indicators associated with the occurrence of moderate to severe SRBDs among HIV-infected people. Healthcare professionals should include snoring screening in the regular course of clinical HIV care.

To systematically review the current literature for articles describing the effect of myofunctional therapy on pediatric obstructive sleep apnea (OSA) and to perform a meta-analysis on the sleep study data.

Three authors (A.B., K.K. and M.C.) independently searched from inception through April 20, 2020 in PubMed/MEDLINE, Scopus, Embase, Google Scholar and The Cochrane Library. Mean difference (MD), standard deviations and 95% confidence intervals were combined in the meta-analysis for apnea-hypopnea index (AHI), mean oxygen saturations, and lowest oxygen saturations (nadir O2).

10 studies with 241 patients met study criteria and were further analyzed. The AHI reduced from 4.32 (5.2) to 2.48 (4.0) events/hr, a 43% reduction. Random effects modeling demonstrated a mean difference in AHI of-1.54 (95% CI -2.24,-0.85)/hr, z-score is 4.36 (p<0.0001). Mean oxygen saturation increased by 0.37 (95% CI 0.06,0.69) percent, z-score is 2.32 (p=0.02). There was no significant increase in nadir O2.

Despite heterogeneity in exercises, myofunctional therapy decreased AHI by 43% in children, and increased mean oxygen saturations in children with mild to moderate OSA and can serve as an adjunct OSA treatment.
