Factors affecting graft healing in laryngotracheal reconstruction: a retrospective single-center experience

PURPOSE

To examine the factors that affect graft healing after laryngotracheal reconstruction (LTR).

METHODS

We conducted a retrospective chart review at King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between January-2008 and October-2023. We included all patients who underwent LTR and required anterior and/or posterior graft placement, while those who underwent procedures without graft placement and those with incomplete information were excluded.

RESULTS

Forty-nine patients were analyzed. Most patients were pediatric (65.3%), male (65.3%), had no coexisting comorbidities (55.1%), and harbored grade 3-4 stenosis (59.2%). Thirty patients (61.2%) underwent open surgery. Various graft complications occurred including infection (n = 1, 2%), dehiscence (n = 3, 6.1%), scar (n = 6, 12.2%), and granulation (n = 29, 59.2%). Only 15 patients (30.65%) achieved the composite status of "healthy" graft. Among 43 patients who had postoperative cultures, positive results for Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were observed in 10 and four patients, respectively. Open surgery and double-stage procedure were significantly associated with higher rates of granulation tissue formation. Pediatric-age group had significantly higher rate of complete epithelization compared to adult-age group. A significantly greater proportion of patients who had unhealthy grafts had open surgery. The rate of double-stage LTR was significantly higher in unhealthy grafts compared to healthy grafts. Prolonged stent duration was linked to various graft-related complications. Multivariate logistic regression analyses showed no statistically significant correlations between various factors and postoperative graft-related complications.

CONCLUSION

Open surgery, double-stage procedure, pediatric age group, and stent duration were not significant risk factors associated with postoperative graft-related complications during LTR in multivariate analysis.

Clinical evaluation of pediatric patients with recurrent respiratory papillomatosis.: A longitudinal study at a Saudi Arabian tertiary care center

OBJECTIVES

To study the clinical evaluation of recurrent respiratory papillomatosis (RRP) patients and the factors associated with the improvement in the Derkay's score as a measure of disease severity.

METHODS

A retrospective cohort that included all juvenile RRP patients who were admitted to King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between September 2015 and June 2022 and underwent surgical debulking.

RESULTS

A total of 16 patients were eligible to join our study. Among them, 7 patients were males. Hoarseness of voice was the most frequent symptom. The median period of the follow-up was 56 months. Complete remission was achieved in 31.3%. The univariate linear regression model revealed that the cidofovir-treated patients had a significant reduction in the change value of Derkay's score compared to those without treatment (regression coefficient= -5.83, 95% confidence interval [CI]: [-11.5 to -0.143], p=0.045). Also, the increased first Derkay's score decreased the change value and subsequently increased the improvement chance of the disease (regression coefficient= -0.424, 95% CI: [-0.764 to -0.083], p=0.018). However, in the multivariate regression model, both variables showed non-significant results.

CONCLUSION

cidofovir treatment and higher Derkay's scores affected the disease improvement.

Relationship Between Patient Activation and Type 2 Diabetes Mellitus Self-management and Clinical Outcomes in Saudi Arabian Primary Care Setting

PURPOSE

Type 2 diabetes mellitus (T2DM) self-management is a comprehensive approach that individuals with T2DM employ to manage and control their condition. Patients' activation, "an individual's knowledge, skill, and confidence for managing their health and health care", has been used as a major driver of self-management. This study aimed to assess the relationship of patient activation with T2DM self-management and clinical outcomes.

DESIGN

A cross-sectional study.

SUBJECTS

Patients with type T2DM who age 18-years and older.

SETTING

The primary care centers in Saudi Arabia.

MEASURES

Patient activation measure (PAM) and the Summary of Diabetes Self-Care Activities (SDSCA).

ANALYSIS

Descriptive statistic, T-test, One-way ANOVA test, Chi-square test, and linear and logistic regressions were performed.

RESULTS

A total of 398 patients, mostly male (54.9%) with a mean age of 53.2 (±10.7) years old participated in the study. The participants' mean of Hemoglobin A1c (HbA1c) was 8.4% (±1.7%) and most of them (74.5%) had an uncontrolled HbA1c level (>7% %). The mean patient activation score was 55.9 (±13.5). 24.4% were at [PA1], 26.7% at [PA2], 37.4% at [PA3], and 11.5% at [PA4]. Patient activation level was positively associated with better glycemic control and self-management behaviors including diet, physical activity, blood glucose self-testing, foot care, and smoking (P < .05) but not with adherence to medication.

CONCLUSIONS

Our findings reveal a positive association between patient activation level and enhanced glycemic control and self-management behaviors and suggest that patient activation-informed self-management interventions are more likely to yield promising health outcomes.

Is adenotonsillectomy effective in improving central apnea events in patients with obstructive sleep apnea? A systematic review and meta-analysis

PURPOSE

To evaluate the effects of adenotonsillectomy on improving central sleep apnea events in children with obstructive sleep apnea (OSA).

METHODS

We searched four online databases for relevant articles published from inception until October 2022. We included studies that measured the number of central apnea events per sleep and central apnea-hypopnea index (CAHI) or central apnea index (CAI) scores in children with OSA before and after adenotonsillectomy. Our primary outcomes were changes in CAI scores, the number of central apnea events per sleep, and CAHI scores after surgery. Our secondary outcomes were changes in total and mixed apnea events, improvement of sleep outcomes, and differences in oxygen or carbon dioxide saturation during sleep. We performed meta-analyses by pooling the mean changes of all included studies with a 95% confidence interval using Stata 17. Subsequently, we performed subgroup analyses based on the presence of comorbidities.

RESULTS

We included 22 studies comprising 1287 patients. Central and total sleep apnea parameters, except for CAHI and mixed apnea index scores, showed significant improvements after surgery. In addition, all respiratory parameters and second and third stages of non-rapid eye movement sleep showed significant postsurgical improvements. Patients with comorbidities showed significant improvements only in the total apnea-hypopnea index, oxygen desaturation index, and minimal oxygen saturation.

CONCLUSION

Adenotonsillectomy improves central apnea events in patients with OSA but not in those with comorbidities.

The Effect of a Patient Activation Tailored Intervention on Type 2 Diabetes Self-Management and Clinical Outcomes: A Study from Saudi Arabian Primary Care Settings

Background

Type 2 diabetes mellitus (T2DM) is a global public health challenge. T2DM self-management, including diet, physical activity, blood glucose self-monitoring, foot care, and adherence to medication, is considered a primary tool for managing diabetes. Patient activation, an individual's knowledge, skill, and confidence in managing their health and healthcare, was recognized to be associated with better T2DM self-management and clinical outcomes. Patient activation intervention has been described as a potential approach for enhancing chronic disease self-management. This study is aimed at examining the effect of a patient activation-tailored intervention on T2DM self-management and clinical outcomes in primary care settings in Saudi Arabia.

Method

A pre- and postintervention study was conducted among ≥18 years old T2DM patients attending primary healthcare centers in Saudi Arabia. Collected data included demographics, clinical data, the Patient Activation Measure (PAM), the Summary of Diabetes Self-Care Activities (SDSCA), the diabetes knowledge test (DKT2), the problem area in diabetes test (PAID-5), and the diabetes quality of life test (DQOL). The intervention was tailored based on the participants' patient activation level. The intervention consisted of monthly face-to-face sessions for three months and a telephone follow-up per month for three months postintervention. Descriptive statistics, a paired sample t-test for scale variables, and Wilcoxon's signed-rank test for categorical variables were used for data analysis.

Results

A total of 82 patients, mostly female (61%) with a mean age of 51.3 ± 9.9 years old, completed baseline and postintervention surveys. After six months of intervention, there was a significant change in patient activation score from 54.74 to 61.58 (p < 0.001), hemoglobin A1c (HbA1c) from 8.38 to 7.55 (p < 0.001), and body mass index (BMI) from 30.90 to 29.16 (p < 0.001). Also, there was a significant change in SDSCA scores (diet from 3.12 to 3.67, exercise from 2.54 to 3.49, and blood glucose self-testing from 2.37 to 3.24) (p < 0.001) and DKT from 6.29 to 7.22 (p = 0.01).

Conclusion

Our findings suggested that tailoring interventions based on patients' activation levels is more likely to yield promising T2DM self-management and clinical outcomes.

Spirometry in laryngotracheal stenosis: a systematic review and meta-analysis

PURPOSE

This study aimed to assess the changes in spirometry parameters or indices after relieving laryngotracheal stenosis (LTS) in adult patients.

METHODS

A systematic review and meta-analysis of studies from PubMed, Scopus, Web of Science, Cochrane Library, and EBSCO databases was conducted for assessing changes in spirometry values after endoscopic balloon dilatation of LTS in adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Relevant data, such as changes in mean spirometry values between preoperative and postoperative interventions, and findings of receiver operating characteristic curve analyses for predicting the need for surgical intervention, were extracted.

RESULTS

Ten studies including 330 patients overall met the inclusion criteria. Significant improvements were observed from preoperative to postoperative mean values of different spirometry parameters and indices. The overall mean differences in peak expiratory flow (ΔPEF), expiratory disproportion index (ΔEDI), and peak inspiratory flow (ΔPIF) were 2.26 L/s (95% CI 2.14-2.38), 27.94 s (95% CI 26.36-29.52), and 1.21 L/s (95% CI 0.95-1.47), respectively. ΔPEF and ΔPIF values increased, while ΔEDI decreased. In predicting the need for surgical intervention, EDI had the highest sensitivity (88%), and forced expiratory volume per second/forced vital capacity had the highest specificity (85%).

CONCLUSION

Spirometry is a valuable tool for assessing patients with LTS. PEF, EDI, and PIF were the most commonly reported spirometry parameters that significantly improved after airway stenosis was relieved.

Comparison Between Flap and Primary Closures of Persistent Tracheocutaneous Fistula: A Scoping Review

Objectives: To compare the susceptibility and complication rates between flap and primary closures for tracheocutaneous fistula (TCF). Methods: We searched 4 online databases (Web of Science, Cochrane Library, PubMed, and Scopus) for relevant articles published from study inception until August 2022. Studies including at least 5 adult or child patients with persistent TCFs who underwent closure surgery via primary or flap repair were included. All included studies reported outcomes of surgical repairs such as successful closure rates and complications. In addition, we performed single-arm meta-analyses for each surgical method using the Open Meta-Analyst software to calculate the pooled event rate with a 95% confidence interval (CI); compared the 2 surgical procedures using the Review Manager software using the risk ratio with 95% CI; and assessed study quality based on the National Heart, Lung, and Blood Institute criteria. Results: Overall, 27 studies with 997 patients were included. No significant difference was observed between the closure success and major complication rates of surgical methods. The primary and flap closures had overall success rates of 0.979 and 0.98, respectively. The overall major complication rates in primary and flap closures were 0.034 and 0.021, respectively; and that of minor were 0.045 and 0.04, respectively. In primary closure, a significant decrease in the success rate with increasing age at the time of decannulation was observed. In addition, the risk of major complications increased with increasing time from decannulation to closure. Conclusions: Both the primary and flap repairs of TCF are effective based on closure success and complication rates; therefore, they are both acceptable therapeutic alternatives, and flap repair can be considered when other techniques have failed. However, further prospective randomized studies comparing these 2 procedures are needed to support our results.

An Absent Lingual Frenulum in a Non-syndromic Premature Infant

The lingual frenulum (LF) is a fold of tissue that connects the tongue to the oral cavity's floor. Abnormal frenula are associated with speech alterations. The absence of the LF is associated with Ehler's Danlos syndrome (EDS). In this case report, we present a premature infant incidentally found to have an absent lingual frenulum, with recurrent desaturations during feeding. The desaturations were believed to be due to the absent lingual frenulum, but they resolved after one month without treatment and were then attributed to apnea of prematurity. Whole exome sequence showed no genetic disorders. The infant is now doing well with no interventions. An absent lingual frenulum warrants molecular genetic testing for EDS. However, it does not warrant any treatment; special considerations are only required during intubation.

Push out bond strength of fiber post to radicular dentin using Q-mix, lemon/garlic extract, and riboflavin activated by photodynamic therapy as a final canal irrigant

OBJECTIVE

The aim of this study was to assess the extrusion bond values of fiber post to radicular dentin when disinfected using different final irrigants lemon garlic extract (LGE), riboflavin (RFP) activated by PDT (photodynamic therapy), and Q-mix 2-in-1.

MATERIALS AND METHODS

Forty single-rooted mandibular premolar teeth were decoronated. Endodontic treatment was performed, and the canals were continually irrigated with normal saline, dried with paper points, and obturated. Post space was prepared by removing gutta-percha using peso-reamers. All specimens were randomly allocated into four groups based on the final irrigant used. Specimens in Group 1 irrigated with: 5.25% NaOCl+17% EDTA, group 2: 5.25% NaOCl+Q-mix 2-in-1, group 3: 5.25% NaOCl+RFP, and group 4: 5.25% NaOCl+LGE. Following final irrigation, a fiber post was placed in the canal space and luted. Samples were sectioned and each section was placed in a universal testing machine to assess bond values. Debonded samples were assessed for failure modes, EBS and modes of failure. For comparisons among groups, the one-way analysis of variance (ANOVA) test and the Post-Hoc Tukey HSD test were used keeping the level of significance at p=0.05.

RESULTS

The cervical section of samples in group 2 (NaOCL+Qmix) (7.11±0.81 MPa) exhibited the maximum value of EBS. However, the apical section of samples in group 3 (5.25% NaOCl+RFP) (3.33±0.26 MPa) displayed minimum extrusion bond values. Group 3 specimens in which final irrigation was performed with RFP established significantly lower bond integrity values than all the other investigated groups coronal (3.77±0.13 MPa), middle (3.60±0.41 MPa), and apical (3.33±0.26 MPa) (p<0.05). Intragroup comparison analysis, the coronal and middle root sections of all the experimental groups displayed comparable outcomes of EBS (p>0.05). However, near the apical section of the root, the bond strength of all the groups declined considerably.

CONCLUSIONS

Q-mix 2-in-1 as the final irrigant displayed the highest extrusion bond strength of fiber-reinforced composite to canal dentin at all three levels coronal, middle and apical. Lemon garlic extract has the potential to be used alternative to ethylene diamine tetra acetic acid as a final irrigant.

Lingual osseous choristoma is a rare, benign, bony tumor without clear pathogenesis. Most patients present with an asymptomatic lump in the posterior tongue, while others may suffer from globus sensation, dysphagia, gagging, or irritation. Here, we present a case of lingual osseous choristoma in a pediatric patient managed with surgical excision.

The Effectiveness of Hyperbaric Oxygen Therapy as Salvage Treatment for Sudden Sensorineural Hearing Loss: A Retrospective Study

Background

Sudden sensorineural hearing loss (SSNHL) is a medical emergency; its etiology is unknown in most cases, The treatment, in turn, is empiric and usually consists of various pharmacological agents, mainly steroids. Hyperbaric oxygen (HBO) therapy is used routinely as salvage therapy for refractory SSNHL. While several studies have demonstrated the effectiveness of HBO therapy as salvage treatment for refractory SSNHL, its results have varied among studies, and its efficacy is still unclear.

Aim

We aimed to stratify the effect of HBO therapy as salvage treatment after the failure of steroid therapy for SSNHL.

Method

This is a retrospective case series that involved eight SSNHL patients in the past three years at King Faisal Specialist Hospital & Research Centre (KFSHRC) in Riyadh, Saudi Arabia. Patients' records were reviewed and statistical analysis was performed.

Results

Eight patients were included in this case series; six of them were males, and the mean age of all patients was 46.88 ±20.9 years. One patient had herpes zoster as the cause of SSNHL and seven patients' disease was of unknown etiology. The mean period for the onset of disease was 4.12 ±2.17 days. One patient was managed with intravenous dexamethasone and the other patients were managed with oral steroids, and all patients were then treated by HBO therapy. Of the patients, two showed significant improvement but the others did not. The cause of SSNHL, age of patients, HBO start and cessation, comorbidities, and disease onset did not affect the improvement in disease in patients (p: ˃0.05).

Conclusion

Moderate-to-severe cases of SSNHL can be improved by HBO treatment along with oral steroids, while this therapy was ineffective in severe and profound cases. No factors could be found to predict improvement in patients.

The effectiveness of patient activation intervention on type 2 diabetes mellitus glycemic control and self-management behaviors: A systematic review of RCTs

BACKGROUND

Type 2 diabetes mellitus T2DM is a major health challenge and associated with several complications and mortality. Self-management behaviors SMBs such as healthy diet, physical activity, blood glucose self-monitoring, foot care and medication adherence are critical part of diabetic care. Empowered or activated patients, are more likely to practice better SMBs. However, the effectiveness of patient activation intervention on T2DM glycemic control and SMBs is not totally well understood.

AIM

To assess the effectiveness of patient activation intervention on T2DM glycemic control and SMBs.

METHOD

A systematic search was undertaken through five databases to find relevant studies published between 2004 and 2018. We included randomized controlled trials with sample size ≥120 and follow up period of ≥12 months and assess the effectiveness of patient activation intervention on T2DM glycemic control and SMBs.

RESULTS

10 RCTs were identified for analysis. The total sample size is 3728 and the combined mean age is 57.3 years. The combined mean BMI is 31.2kg/m² (obese). Seven intervention demonstrated a significant reduction in HbA1c, ranged from 0.36 to 0.80%. All interventions presented an improvement in at least one self-management behavior.

DISCUSSION AND CONCLUSION

Patient activation intervention showed a significant positive effect on T2DM glycemic control and SMBs, particularly physical activity, healthy diet, foot care and blood glucose self-monitoring. The effectiveness on SMBs was seen across different intervention strategies, modes of delivery, length of intervention, and number of providers. Better effectiveness on HbA1c was associated with poorly controlled participants, culturally tailored-intervention, and in-person sessions intervention combined with telephone calls follow up.

The Effects of Twitter Users' Gender and Weight on Viral Behavioral Intentions Toward Obesity-Related News

In this study, male and female participants were exposed to identical news stories covering obesity topics paired with tweets from Twitter users. Our study aimed at understanding how obesity-related news combined with user-generated social media posts (i.e., tweets) affect consumers' evaluations of online content and viral behavioral intentions (the intentions to like, share, and comment). An experiment (N = 316) explored how gender and weight of a Twitter user (tweeter) affect participants' evaluations and viral behavioral intentions toward news stories. Participants differed in their evaluations of and viral behavioral intentions for news stories as a function of Twitter users' gender and weight, as well as participants' gender. While participants expressed more favorable attitudes toward news stories paired with tweets by overweight than healthy females (with the opposite true for tweets by male users), participants expressed greater viral behavioral intentions for news stories paired with tweets by healthy weight than overweight user. These effects were more pronounced among male than female participants. Findings are discussed within the context of social media posts and their persuasive effects in relation to attitude and behavior changes.

Just Add a Verse from the Quran: Effects of Religious Rhetoric in Gain- and Loss-Framed Anti-Alcohol Messages with a Palestinian Sample

This experiment investigated the effects of message framing (gain vs. loss) and religious rhetoric (religious vs. non-religious) on the expression of anti-alcohol civic intentions with a sample (N = 80) of Palestinian young adults. Results showed that the main effects of message framing (gain > loss) and religious rhetoric (non-religious > religious) on anti-alcohol civic intentions were significant. Furthermore, the study showed that viral behavioral intentions were strongly and significantly associated with expressing anti-alcohol civic intentions, with larger explanatory power for gain-framed PSAs that used a religious rhetoric. Additionally, a serial mediation model showed that the effect of religious rhetoric on anti-alcohol civic intentions was successfully mediated by the serial combination of attitudes toward the PSA and viral behavioral intention for gain-framed PSAs, but not for loss-framed PSAs. Findings are discussed within the framework of persuasion models.
