Biomarkers are not available for monitoring the onset and progression of coronary artery disease (CAD) in patients with obstructive sleep apnea (OSA), a major risk factor for arteriosclerotic cardiovascular diseases. This study aimed to test for correlation between circulating anti-Sorting Nexins 16 antibody (SNX16-Ab) levels, CAD history and clinical parameters of patients with OSA. Sixty-four healthy donors, 82 adults with OSA, and 96 with acute coronary syndrome (ACS) were studied. Serum samples were collected at diagnostic polysomnography in the OSA group or at the disease onset in the ACS group. Serum SNX16-Ab levels were measured by amplified luminescence proximity homogeneous assay (AlphaLISA), and correlation between SNX16-Ab levels and clinical parameters was analyzed. SNX16-Ab levels and apnea-hypopnea index (AHI) were weakly correlated. Additionally, logistic regression analyses of OSA group identified that elevated SNX16-Ab level associated with the history of CAD. Circulating SNX16-Ab could increase during CAD pathogenesis in patients with OSA. Further prospective studies are required to prove the predictive potential of SNX16-Ab level in CAD onset of patients with OSA.

Nasal airway obstruction may exacerbate sleep apnea and is difficult to quantify on clinical examination. In this study, we examined the relationship among nasal patency, the frequency of sleep apnea events, and effective nasal continuous positive air pressures. Acoustic rhinometry was used as an objective measurement of nasal cross-sectional areas in 76 patients without nasal symptoms who underwent study with diagnostic polysomnography because of obstructive sleep apnea. Patients with persistent obstructive sleep apnea were titrated to nasal continuous positive air pressure in a split night study. All subjects had a mean apnea/hypopnea index of 28, and those with obstructive sleep apnea had a mean apnea/hypopnea index of 43. Mean cross-sectional areas 1 to 4 cm into the nose were 1.7, 1.1, 2.1, and 2.8 cm 2 , respectively (F = 39, p < 0.001). However, there was no correlation between the apnea/hypopnea index and the cross-sectional area at the four distances (r = 0.03, 0.06, 0.02, and 0.02, respectively, p = not significant). Correlations between nasal continuous positive air pressures and cross-sectional areas did not reveal a significant relationship at any of the four sites (r = 0.09, 0.07, −0.03, 0.00, respectively). Findings in patients with apnea were also compared with those in patients without apnea and significant differences were not found (F = 0.019, p = not significant). Although it would seem intuitive that increased nasal obstruction is associated with the severity of obstructive sleep apnea and difficulty with the use of nasal continuous positive air pressure, this study shows that nasal patency, as measured by acoustic rhinometry, does not correlate with the severity of obstructive sleep apnea, as determined by the apnea/hypopnea index or the effective nasal continuous positive air pressure.

Unexpected Findings

Summary Background: Compression therapy (CT) is the stronghold of treatment of venous leg ulcers. We evaluated 5 modalities of CT in a prospective open pilot study using a unique trial design. Patients and methods: A group of experienced phlebologists assigned 31 consecutive patients with 35 venous ulcers (present for 2 to 24 months with no prior CT) to 5 different modalities of leg compression, 7 ulcers to each group. The challenge was to match the modality of CT with the features of the ulcer in order to achieve as many healings as possible. Wound care used standard techniques and specifically tailored foam pads to increase local pressure. CT modalities were either stockings Sigvaris® 15-20, 20-30, 30-40 mmHg, multi-layer bandages, or CircAid® bandaging. Compression was maintained day and night in all groups and changed at weekly visits. Study endpoints were time to healing and the clinical parameters predicting the outcome. Results: The cumulative healing rates were 71%, 77%, and 83% after 3, 6, and 9 months, respectively. Univariate analysis of variables associated with nonhealing were: previous surgery, presence of insufficient perforating and/or deep veins, older age, recurrence, amount of oedema, time of presence of CVI and the actual ulcer, and ulcer size (p <0.05-<0.001). The initial ulcer size was the best predictor of the healing-time (Pearson r=0.55, p=0.002). The modality of CT played an important role also, as 19 of 21 ulcers (90%) healed with stockings but only 8 of 14 with bandages (57%; p=0.021). Regression analysis allowed to calculate a model to predict the healing time. It compensated for the fact that patients treated with low or moderate compression stockings were at lower risk of non-healing. and revealed that healing with stockings was about twice as rapid as healing with bandages. Conclusion: Three fourths of venous ulcers can be brought to healing within 3 to 6 months. Healing time can be predicted using easy to assess clinical parameters. Irrespective of the initial presentation ulcer healing appeared more rapid with the application of stockings than with bandaging. These unexpected findings contradict current believes and require confirmation in randomised trials.

The purpose of this study was to evaluate whether Low-Level Laser Therapy (LLLT) improves the healing of the implant surgical site with clinical and biochemical parameters.Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to two groups - the control group and the test group. The test group received laser energy at a power of 2J/cm 2 with a total of 4-6J energy over each implant. Clinical parameters (Implant Stability Quotient, probing index, modified sulcus bleeding index)and osteoprotegerin (OPG) were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months).The test group showed significantly higher implant stability quotient compared to thecontrol group at 2 weeks(57.93±3.95 and 35.67±3.08; p&lt;0.01) and 3months(58.86±3.75 and 67.06±3.78; p&lt;0.01). A significant rise in OPG levels of the test group(686.30±125.36pg/ml at baseline and 784.25±108.30pg/ml at 3months;p&lt;0.01) was seen contrary to significant decline in the control group (839.50±249.08pg/ml at baseline,415.30±78.39pg/ml at 3months;p&lt;0.01). Within the limitations of the study, the study suggests that the healing of peri-implant hard and soft tissues may be enhanced with the use of LLLT as an explicit modality during the post-operative period.
