- Introduction: Unrefreshing sleep is one of the diagnostic criteria in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), which could be explained by sleep disorders, for example obstructive sleep apnea, reported in our previous study with polysomnography. Our previous findings also indicate difficulties in emotional regulation when measuring alexithymia by TAS-20 (Toronto Alexithymia Scale) and level of emotional awareness by LEAS (Level of Emotional Awareness Scale) in ME/CFS patients. However, the reasons for this are unknown. The purpose of this study was to investigate correlations between data from subjective emotional regulation and polysomnography.Methods: Twenty-three ME/CFS patients (5 men and 18 women) of mean age 43, and 30 matched healthy controls (9 males and 21 women) of mean age 45, filled in TAS-20, LEAS, and Hospital Depression and Anxiety Scale (HADS). A polysomnography was performed on patients but not on healthy controls. Thus, values of normal population were used for sleep evaluation in ME/CFS patients.Result: There were significant differences between patients and controls in several aspects of emotional regulation, for example LEAS-self and LEAS-total. Seventy percent of the patients had increased numbers of awakenings (shifts from any sleep stage to awake), 22% had obstructive sleep apneas, and 27% had periodic limb movements. Correlation analysis showed that number of awakenings significantly correlated with LEAS-self and LEAS-total, p < 0.01, respectively. There were no other significant correlations.Conclusion: This pilot study demonstrated significant correlations between reduced emotional awareness and number of awakenings in polysomnography. Future studies with larger cohorts need to be conducted.

- Innate lymphoid cells (ILCs) are increasingly appreciated as important participants in homeostasis and inflammation. Substantial plasticity and heterogeneity among ILC populations have been reported. Here we have delineated the heterogeneity of human ILCs through single-cell RNA sequencing of several hundreds of individual tonsil CD127(+) ILCs and natural killer (NK) cells. Unbiased transcriptional clustering revealed four distinct populations, corresponding to ILC1 cells, ILC2 cells, ILC3 cells and NK cells, with their respective transcriptomes recapitulating known as well as unknown transcriptional profiles. The single-cell resolution additionally divulged three transcriptionally and functionally diverse subpopulations of ILC3 cells. Our systematic comparison of single-cell transcriptional variation within and between ILC populations provides new insight into ILC biology during homeostasis, with additional implications for dysregulation of the immune system.

- PURPOSE: Our previous randomized controlled trial (RCT) of children with obstructive sleep apnea (OSA) showed no significant differences between adenotonsillectomy (ATE) and adenotonsillomy (ATE) in improving nocturnal respiration and symptoms after one year. This is the continuous report with the evaluation of postoperative morbidity concerning bleeding and pain.METHODS: A double-blinded RCT including 79 children, aged 2-6 years, with moderate to severe OSA, randomized to either ATE (n = 40) or ATT (n = 39). From one to ten days postoperatively, parents filled in a logbook with six pain-related outcomes (parent and child grading pain at different levels, days of analgesic use and return to normal diet). Peri- and postoperative bleeding were also registered.RESULTS: 63 patients (80%) returned the logbook. There were significant differences between groups in only two of the six pain-related outcomes in favor of the ATT group; first day when the children graded themselves as pain free (p = 0.021, Log Rank Test), and first day the caregiver estimated pain VAS ≤ 5 (p = 0.007, Log Rank Test). Two (5%) cases of postoperative bleeding occurred in the ATE group, one of which needed a return to theatre. No case of postoperative bleeding was seen in the ATT group.CONCLUSIONS: The results from this RCT are in line with previous comparative studies between ATT and ATE. Children operated with ATT had significantly less postoperative pain in one-third of the outcomes, and less bleeding than ATE. However, as the differences in morbidity between the surgical methods were minor the clinical significance is uncertain.TRIAL REGISTRATION: This study was approved by the Swedish Regional Ethics Board in Stockholm, Sweden (Dnr 2011/925-32 and 2013/2274-32) and registered at ClinicalTrials.gov (Trial registration number NCT01676181).

- Objectives The objective of this study was to longitudinally describe the history of tonsil surgery in Swedish children and adolescents regarding incidence, indications for surgery, surgical methods and the age and gender distributions. Setting A retrospective longitudinal population-based cohort study based on register data from the Swedish National Patient Register (NPR) and population data from Statistics Sweden. Participants All Swedish children 1-<18â €..years registered in the NPR with a tonsil surgery procedure 1987-2013. Results 167â €..894 tonsil surgeries were registered in the NPR 1987-2013. An increase in the total incidence rate was observed, from 22/10â €..000 person years in 1987 to 47/10â €..000 in 2013. The most marked increase was noted in children 1-3â €..years of age, increasing from 17 to 73/10â €..000 person years over the period. The proportion children with obstructive/sleep disordered breathing (SDB) indications increased from 42.4% in 1987 to 73.6% in 2013. Partial tonsillectomy, tonsillotomy (TT), increased since 1996 and in 2013 55.1% of all tonsil procedures were TTs. Conclusions There have been considerable changes in clinical practice for tonsil surgery in Swedish children over the past few decades. Overall, a doubling in the total incidence rate was observed. This increase consisted mainly of an increase in surgical procedures due to obstructive/SDB indications, particularly among the youngest age group (1-3â €..years old). TT has gradually replaced tonsillectomy as the predominant method for tonsil surgery.

- Conclusions: This follow-up showed a stable and significant decrease in median oxygen desaturation index 4% (ODI(4)) values over the years. Approximately two-thirds of the patients fulfilled the success criteria (ODI4 reduction of 50% and andlt;20) after 15 years. A majority had improved/cured excessive daytime sleepiness (EDS) and were satisfied. No increased mortality rate was seen. Objectives: To evaluate sleep apnoea recordings and symptoms in patients with obstructive sleep apnoea syndrome 15 years after uvulopalatopharyngoplasty (UPPP) compared to baseline and previous follow-ups. Methods: This was a non-randomized, prospective intervention study on 50 patients who underwent UPPP during 1985-88. Their initial median age was 49 years (range 38-71) and ODI4 was 26.5 (4-82). Results: In all, 13 patients had died; 26 patients underwent sleep apnoea recordings. Median ODI4 had decreased from 26.5 (range 4-82) to 8.5 (0-60), p andlt; 0.01, a mean reduction of 52%; 65% of patients achieved the success criteria. One-third was objectively categorized as non-snorers. Median body mass index was unchanged. The questionnaires were answered by 32 of 37 patients; 88% reported improved or cured EDS and 78% were satisfied. Pharyngeal disturbances ratings were low. The standardized mortality rate did not differ from the general Swedish population.

- Objectives/HypothesisOur previous study showed that modified uvulopalatopharyngoplasty (UPPP), including tonsillectomy, significantly improved nocturnal respiration in obstructive sleep apnea syndrome (OSAS) patients. This is a continuous study of changes in daytime sleepiness and quality of life.Study DesignProspective randomized controlled trial (RCT), two parallel arms.MethodsSixty‐five patients with apnea‐hypopnea index ≥ 15, body mass index < 36, Epworth Sleepiness Scale (ESS) ≥ 8, Friedman stage I or II, failing nonsurgical treatment. The intervention group (n = 32) underwent surgery, and the controls (n = 33) had no treatment. At baseline and the 7‐month follow‐up, polysomnography, questionnaires, and vigilance tests were implemented.ResultsAll patients answered the questionnaires, and 48 took the vigilance test. Epworth Sleepiness Scale decreased significantly in the intervention group, from a mean (standard deviation) of 12.5(3.2) to 6.8(3.9), but nonsignificantly in the control group, from 12.9(3.1) to 12.5(3.9), a significant group difference (P < 0.001). The physical and mental component score on the Short Form‐36 questionnaire increased significantly in the intervention group, from a mean 47.8(8.3) to 51.2(8.8) and from 42.1(10.6) to 48.1(9.7), respectively, but with nonsignificant changes in the controls: 49.0(9.0) to 48.3(9.1) and 41.0(10.2) to 42.7(11.5), significant group differences (P = 0.007, P = 0.031), respectively. The sleep latency/vigilance test showed a significant mean increase in the intervention group of 7(12.4) minutes and a decrease in the controls of 2.2(10.6), a significant group difference (P = 0.011). There were significant correlations between changes in subjective outcomes and nocturnal respiration.ConclusionThis RCT shows that modified UPPP was effective in improving daytime sleepiness and quality of life in OSAS patients. It strengthens the body of evidence on the potential effect of surgery offered to selected patients.

- ObjectiveOur previous randomized controlled trial of patients with obstructive sleep apnea syndrome (OSAS) showed that modified uvulopalatopharyngoplasty (UPPP), including tonsillectomy, significantly improved nocturnal respiration, daytime sleepiness, and quality of life in the intervention group compared to controls who had delayed surgery after 6 months. This is the continuous report with the 6‐ and 24‐month postoperative results.Study DesignSingle‐center prospective cohort study.MethodsSixty‐five patients with apnea–hypopnea index (AHI) ≥ 15, body mass index (BMI) < 36, Epworth Sleepiness Scale (ESS) ≥ 8, and Friedman stage I or II underwent UPPP after failing nonsurgical treatment. The results from polysomnography and ESS at 6 and 24 months were compared to baseline.ResultsEight percent and 20% dropped out from the 6‐ and 24‐month follow‐ups, respectively. The AHI value decreased significantly from mean (standard deviation) 52.9 (20.5) at baseline to 23.6 (20.2) after 6 months, and to 24.1 (20.9) after 24 months (P < 0.001). Patients with tonsil size 2, and 3 to 4, had significant reductions in the AHI after both follow‐ups. The median ESS score decreased significantly from 13 (range 8–21) to 6.5 (1–18) after 6 months, and to 5 (2–17) after 24 months (P < 0.001). The BMI remained unchanged. There were significant modest correlations for the reductions in AHI and ESS after 24 months.ConclusionModified UPPP was effective in improving nocturnal respiration and daytime sleepiness in OSAS patients at both 6‐ and 24‐month follow‐up. Patients with tonsil size 2, and 3 to 4, benefitted similarly from surgery with improved respiration.

- OBJECTIVE: To assess the 6-month efficacy of uvulopalatopharyngoplasty (UPPP) compared with expectancy in selected patients with obstructive sleep apnoea syndrome (OSAS).DESIGN: A prospective single-centre randomised controlled trial with two parallel arms stratified by Friedman stage and body mass index (BMI).PARTICIPANTS: 65 consecutive patients with moderate to severe OSAS (apnoea-hypopnoea index (AHI) ≥15 events/h sleep), BMI <36 kg/m(2), Epworth sleepiness scale ≥8, Friedman stage I or II.INTERVENTION: Surgical treatment with UPPP. The control group underwent UPPP after a delay of 6 months.OUTCOMES: Changes in AHI and other polysomnography parameters at baseline compared with the 6-month follow-up.RESULTS: All patients (32 in the intervention group and 33 in the control group) completed the trial. The mean (SD) AHI in the intervention group decreased significantly (p<0.001) by 60% from 53.3 (19.7) events/h to 21.1 (16.7) events/h . In the control group the mean AHI decreased by 11% from 52.6 (21.7) events/h to 46.8 (22.8) events/h, with a significant difference between the groups (p<0.001). The mean time in the supine position and the BMI were unchanged in both groups. Subgroup analyses for Friedman stage, BMI group and tonsil size all showed significant reductions in AHI in the intervention group compared with controls. There were no severe complications after surgery.CONCLUSIONS: This trial demonstrates the efficacy of UPPP in treating selected patients with OSAS with a mean reduction in AHI of 60% compared with 11% in controls, a highly significant and clinically relevant difference between the groups.TRIAL REGISTRATION NUMBER: NCT01659671.
