Consensus minimum core data elements adapted to peripheral vascular intervention in the drug-eluting era: Consensus report from the Registry Assessment of Peripheral Interventional Devices (RAPID) Pathways "LEAN" working group.

Registry Assessment of Peripheral Interventional Devices (RAPID) initiated the Pathways Program to provide a transparent, collaborative forum in which to pursue insights into multiple unresolved questions on benefit-risk of paclitaxel-coated devices, including understanding the basis of the mortality signal, without a demonstrable potential biological mechanism, and whether the late mortality signal could be artifact intrinsic to multiple independent prospective randomized data sources that did not prespecify death as a long-term end point. In response to the directive, the LEAN-Case Report Form working group focused on enhancements to the RAPID Phase I Minimum Core Data set through the addition of key clinical modifiers that would be more strongly linked to longer-term mortality outcomes after peripheral arterial disease intervention in the drug-eluting device era, with the goal to have future mortality signals more accurately examined.

Comparison of intravascular ultrasound, optical coherence tomography, and conventional angiography-guided percutaneous coronary interventions: A systematic review, network meta-analysis, and meta-regression.

BACKGROUND: Intracoronary imaging modalities, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), provide valuable supplemental data unavailable on coronary angiography (CA) and have shown to improve clinical outcomes. We sought to compare the clinical efficacy of IVUS, OCT, and conventional CA-guided percutaneous coronary interventions (PCI). METHODS: Frequentist and Bayesian network meta-analyses of randomized clinical trials were performed to compare clinical outcomes of PCI performed with IVUS, OCT, or CA alone. RESULTS: A total of 28 trials comprising 12,895 patients were included. IVUS when compared with CA alone was associated with a significantly reduced risk of major adverse cardiovascular events (MACE) (risk ratio: [RR] 0.74, 95% confidence interval: [CI] 0.63-0.88), cardiac death (RR: 0.64, 95% CI: 0.43-0.94), target lesion revascularization (RR: 0.68, 95% CI: 0.57-0.80), and target vessel revascularization (RR: 0.64, 95% CI: 0.50-0.81). No differences in comparative clinical efficacy were found between IVUS and OCT. Rank probability analysis bestowed the highest probability to IVUS in ranking as the best imaging modality for all studied outcomes except for all-cause mortality. CONCLUSION: Compared with CA, the use of IVUS in PCI guidance provides significant benefit in reducing MACE, cardiac death, and revascularization. OCT had similar outcomes to IVUS, but more dedicated studies are needed to confirm the superiority of OCT over CA.

Is it Necessary for the Use of Fluorinated Compounds to Formulate Reverse Micelles in a Supercritical Fluid? Searching the Best Cosurfactant to Create "Green" AOT Reverse Micelle Media.

Herein, we report the effect of employing two different alcohols, such as n-pentanol and 2,2,3,3,4,4,5,5-octafluoro pentanol (from now on F-pentanol), into 1,4-bis-2-ethylhexylsulfosuccinate (AOT) reverse micelles (RMs), to determine the interfacial activity and establish the best candidate to act as a cosurfactant in supercritical RMs. Dynamic light scattering (DLS), Fourier transform infrared (FT-IR), and fluorescence emission spectroscopy allowed us to determine and understand the behavior of alkanols in RMs. As a result, we found interesting displacements of alkanol molecules within the RMs, suggesting that the electrostatic interaction between SO3- and Na+ weakens because of new interactions of n-pentanol with SO3- through H-bonds, changing the curvature of the micellar interface. According to FT-IR and DLS studies, F-pentanol forms a RM polar core interacting through intermolecular H-bonds, suggesting no perturbations of the AOT RM interface. Hence, n-pentanol was selected as a cosurfactant to form supercritical RMs, which is confirmed by red edge excitation shift studies, using C343 as a molecular probe. Herein, we were able to create RMs under supercritical conditions without the presence of modified surfactants, fluorinated or multitailed compounds, which, to the best of our knowledge, was not shown before.

Challenges to medication adherence with intranasal corticosteroid irrigations.

BACKGROUND: The purpose of this study was to investigate real-world adherence to intranasal corticosteroid irrigations using pharmacy data and assess factors associated with low adherence. METHODS: Patients undergoing treatment with corticosteroid irrigations for any diagnosis during a 2-year period were prospectively recruited. Subjects completed a one-time set of questionnaires including the Barriers to Care Questionnaire (BCQ), 22-item Sino-Nasal Outcome Test (SNOT-22), and a questionnaire assessing their experience with corticosteroid irrigations. Pharmacy data was used to calculate the medication possession ratio (MPR), a measure of medication adherence graded from 0 to 1. RESULTS: Seventy-one patients were enrolled. Patient diagnoses included chronic rhinosinusitis (CRS) without nasal polyps (n = 37), CRS with nasal polyps (n = 24), or a non-CRS diagnosis, most commonly chronic rhinitis (n = 10). The MPR for the overall group was 0.44 ± 0.33. Just 9.9% of patients had a perfect MPR of 1. Despite low MPR, only 19.7% of patients reported problems taking the medication when directly asked. Lower education resulted in lower MPR (unstandardized B = 0.065, p = 0.046). Increasing BCQ score, indicating higher barriers to care, was associated with lower MPR (unstandardized B = -0.010, p = 0.033). The lower the MPR, the worse the patient SNOT-22 scores (unstandardized B = -15.980, p = 0.036). CONCLUSION: Adherence to corticosteroid irrigations was low and patients underreported issues with their medication. Education and barriers to care were associated with lower adherence, which, in turn, was associated with worse sinonasal quality of life.

Factors Impacting Follow-Up Care in Allergic Fungal Rhinosinusitis.

OBJECTIVE: The purpose of this study was to analyze barriers to medical care and follow-up in patients with allergic fungal rhinosinusitis (AFRS). STUDY DESIGN: Cross-sectional questionnaire-based study with retrospective chart review. SETTING: Tertiary Medical Center. METHODS: Subjects with AFRS and chronic rhinosinusitis with nasal polyps (CRSwNP) were prospectively recruited for completion of the Barriers to Care Questionnaire (BCQ) and formal chart review. RESULTS: Fifty-nine AFRS and 51 CRSwNP patients participated. AFRS patients were more likely to be lost to follow-up within 6 months of surgery (35.6% vs 17.7%, P = 0.04) and no-show at least 1 appointment (20.3% vs 5.9%, P = 0.03) compared to CRSwNP patients. Men with AFRS were more likely to have only a single follow-up visit (37.0% vs 3.1%, P < 0.001) and be lost to follow-up (66.7% vs 9.4%, P < 0.001) than women. There were no significant differences in the BCQ between groups; however, rate of questionnaire completion was lower in the AFRS group than the CRS group (62.7% vs 80.4%, P = 0.042). AFRS patients who did not complete the BCQ were more likely to be male (63.6% vs 35.1%, P = 0.034), lost to follow-up (77.3% vs 10.8%, P < 0.0001), and have a single follow-up visit (40.9% vs 5.4%, P < 0.0001). Younger age was associated with increased likelihood of having a single follow-up visit (odds ratio 1.143, 95% CI 1.022-1.276). CONCLUSION: Young, male AFRS patients are more frequently lost to follow-up after surgery and less likely to complete questionnaires assessing barriers to care. Further investigation is needed to assess barriers to follow-up in these at-risk groups.

Comparison of Quality of Life Outcomes for Percutaneous Versus Transcutaneous Implantable Hearing Devices: A Systematic Review and Meta-analysis.

OBJECTIVE: To compare quality of life (QOL) outcomes of percutaneous and transcutaneous bone conduction devices (pBCD and tBCD, respectively). DATABASES REVIEWED: Pubmed, Scopus, CINAHL. METHODS: A systematic review was performed searching for English language articles from inception to March 15, 2023. Studies reporting QOL outcomes measured using a validated tool following implantation of either pBCDs or tBCDs were considered for inclusion. QOL outcomes included scores for Glasgow Benefit Inventory, Glasgow Children's Benefit Inventory, Abbreviated Profile of Hearing Aid Benefit, and the Speech, Spatial, and Qualities of Hearing Scale. A meta-analysis of continuous measures was performed. RESULTS: A total of 52 articles with 1,469 patients were included. Six hundred eighty-nine patients were implanted with pBCDs, and the remaining 780 were implanted with tBCDs. Average Glasgow Benefit Inventory scores for the tBCD group (33.0, 95% confidence interval [22.7-43.3]) were significantly higher than the pBCD group (30.9 [25.2-36.6]) (Δ2.1 [1.4-2.8], p < 0.0001). Mean Glasgow Children's Benefit Inventory scores (Δ3.9 [2.0-5.8], p = 0.0001) and mean gain in Abbreviated Profile of Hearing Aid Benefit scores (Δ5.6 [4.8-6.4], p < 0.0001) were significantly higher among patients implanted with tBCDs than those implanted with pBCDs. Patients implanted with tBCDs also had significantly higher gains on the Speech (Δ1.1 [0.9-1.3], p < 0.0001), Spatial (Δ0.8 [0.7-0.9], p < 0.0001), and Qualities of Hearing (Δ1.2 [1.1-1.3], p < 0.0001) portions of the Speech, Spatial, and Qualities of Hearing Scale than those implanted with pBCDs. CONCLUSIONS: Patients implanted with transcutaneous devices had better QOL outcomes than those implanted with percutaneous devices.

Comparison of Transcutaneous and Percutaneous Implantable Hearing Devices for the Management of Congenital Aural Atresia: A Systematic Review and Meta-Analysis.

OBJECTIVE: To compare audiometric outcomes, complications, and revisions required for percutaneous (pBCD) versus transcutaneous (tBCD) implantable bone-conduction devices for the treatment of hearing loss associated with congenital aural atresia (CAA).Databases Reviewed.PubMed, Scopus, CINAHL. METHODS: A systematic review was performed searching for English language articles from inception to December 14, 2022. Studies reporting audiometric outcomes or complications for either pBCDs or tBCDs for the treatment of CAA were selected for inclusion. A meta-analysis of single means and meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. RESULTS: A total of 56 articles with 756 patients were selected for inclusion. One hundred ninety patients were implanted with pBCDs, whereas the remaining 566 were implanted with tBCDs. Mean pure-tone audiometry improvement in the pBCD group (39.1 ± 1.1 dB) was significantly higher than in the tBCD group (34.6 ± 1.6 dB; Δ4.5 dB; 95% confidence interval, 4.2-4.7 dB; p < 0.0001). The average improvement in speech reception threshold was 38.6 ± 2.5 dB in the percutaneous group as compared with 32.7 ± 1.6 dB in the transcutaneous group (Δ5.9 dB [5.3-6.5 dB], p < 0.0001). Overall complication rates for patients implanted with pBCDs and tBCDs were 29.0% (15.7-44.4%) and 9.4% (6.5%-13.0%), respectively (Δ19.6% [12.0-27.7%], p < 0.0001). CONCLUSIONS: Patients with CAA implanted with pBCDs had significantly better audiometric outcomes than those implanted with tBCDs. However, complication rates were significantly higher among the pBCD group.

Sexual history of patients with human papillomavirus positive and negative oropharyngeal cancer: A systematic review and meta-analysis.

BACKGROUND: Increased sexual activity is associated with higher human papillomavirus (HPV) rates; however, there is a lack of analysis comparing the sexual history of patients with HPV positive and HPV negative oropharyngeal cancer (OPC). METHODS: In this meta-analysis, PubMed, Scopus, and CINAHL were searched for articles that included patients with OPC and reported information regarding HPV status and either history of oral sex, number of sexual partners, or sexually transmitted infections (STI). RESULTS: A total of 11 studies were included with 3296 patients with OPC. Patients with HPV positive OPC were more likely than patients with HPV negative OPC to report a history of oral sex (92%, 95% CI: 87.0-97.0 vs. 74.5%, 95% CI: 50.6-98.4, p < 0.0001), higher mean number of sexual partners (18.4 partners, 95% CI: 1.5-35.4 vs. 7.2 partners, 95% CI: 1.0-13.4, p < 0.0001), and more frequent history of STI (23.7%, 95% CI: 18.4-29.0 vs. 8.8%, 95% CI: 4.7-12.8, p = 0.0001). CONCLUSIONS: Compared to patients with HPV negative OPC, our analysis shows a larger proportion of patients with HPV positive OPC had participated in oral sex, had a higher number of sexual partners, and had a higher proportion of STI history.

Utilization of RNA sequencing to investigate olfactory dysfunction in chronic rhinosinusitis without nasal polyps: A pilot study.

Objectives: Prior research on olfactory dysfunction in chronic rhinosinusitis (CRS) has focused on patients with polyps and suggests that direct inflammation of the olfactory cleft mucosa plays a contributory role. The purpose of this study was to evaluate gene expression in superior turbinate mucosal specimens, comparing normosmic and dysosmic CRS patients without polyps (CRSsNP). Methods: Tissue samples were obtained from the superior turbinates of patients with CRSsNP at the time of endoscopic sinus surgery. Samples subsequently underwent RNA sequencing and functional analysis to investigate biological pathways associated with differentially expressed genes between dysosmic (n = 7) and normosmic (n = 4) patients. Results: Differential gene expression analysis comparing dysosmic and normosmic CRSsNP patients showed upregulation of 563 genes and downregulation of 327 genes. Using stringent criteria for multiple comparisons, one upregulated gene (Immediate Early Response 3 [IER3]) had an false discovery rate (FDR) correction adjusted P value considered statistically significant (P < 0.001, fold change 2.69). Reactome functional analysis revealed eight biological pathways significantly different between dysosmic and normosmic patients (P < 0.05, FDR correction) including IL-4 and IL-13 signaling, IL-10 signaling, and rhodopsin-like receptors. Conclusions: RNA sequencing of the superior turbinates in patients with CRSsNP can provide valuable information regarding biological pathways and genes involved in olfactory dysfunction. This study supports literature suggesting that Type 2 inflammation may play a role in olfactory dysfunction in at least some patients with CRSsNP. This study also prompts questions regarding the role of IL-10, rhodopsin-like receptors, and IER3 in the pathogenesis of olfactory dysfunction.

Health care disparities and chronic rhinosinusitis: Does neighborhood disadvantage impact outcomes in sinonasal disease?

OBJECTIVE: Socioeconomic status (SES) is linked to health outcomes but has not been well studied in patients with chronic rhinosinusitis (CRS). The area deprivation index (ADI) is a comprehensive measure of geographic SES that ranks neighborhood disadvantage. This investigation used ADI to understand the impact of neighborhood disadvantage on CRS treatment outcomes. METHODS: A total of 642 study participants with CRS were prospectively enrolled and self-selected endoscopic sinus surgery (ESS) or continued appropriate medical therapy as treatment. The 22-item SinoNasal Outcome Test (SNOT-22) and Medical Outcomes Study Questionnaire Short-Form 6-D (SF-6D) health utility value scores were recorded pre- and post-treatment. Using residence zip codes, national ADI scores were retrospectively assigned to patients. Spearman's correlation coefficients (Rs) and Cramer's V effect size (φc) with 95% confidence interval (CI) were calculated. RESULTS: A history of ESS was associated with significantly worse ADI scores compared to no history of ESS (φc = 0.18; 95% CI: 0.10, 0.25; p < 0.001). Baseline total SNOT-22 (Rs = 0.14; 95% CI: 0.06, 0.22; p < 0.001) and SF-6D values (Rs = -0.20; 95% CI: -0.27, -0.12; p < 0.001) were significantly negatively correlated with national ADI rank. No significant correlations between ADI and within-subject improvement, or achievement of >1 minimal clinically important difference, in SNOT-22 or SF-6D scores after treatment were found. CONCLUSIONS: Geographic socioeconomic deprivation was associated with worse baseline disease severity and history of prior surgical intervention. However, ADI did not correlate with improvement in disease-specific outcomes. The impact of socioeconomic deprivation on outcomes in CRS requires further investigation.

Sensing and Control Strategies Used in FES Systems Aimed at Assistance and Rehabilitation of Foot Drop: A Systematic Literature Review.

Functional electrical stimulation (FES) is a rehabilitation and assistive technique used for stroke survivors. FES systems mainly consist of sensors, a control algorithm, and a stimulation unit. However, there is a critical need to reassess sensing and control techniques in FES systems to enhance their efficiency. This SLR was carried out following the PRISMA 2020 statement. Four databases (PubMed, Scopus, Web of Science, Wiley Online Library) from 2010 to 2024 were searched using terms related to sensing and control strategies in FES systems. A total of 322 articles were chosen in the first stage, while only 60 of them remained after the final filtering stage. This systematic review mainly focused on sensor techniques and control strategies to deliver FES. The most commonly used sensors reported were inertial measurement units (IMUs), 45% (27); biopotential electrodes, 36.7% (22); vision-based systems, 18.3% (11); and switches, 18.3% (11). The control strategy most reported is closed-loop; however, most of the current commercial FES systems employ open-loop strategies due to their simplicity. Three main factors were identified that should be considered when choosing a sensor for gait-oriented FES systems: wearability, accuracy, and affordability. We believe that the combination of computer vision systems with artificial intelligence-based control algorithms can contribute to the development of minimally invasive and personalized FES systems for the gait rehabilitation of patients with FDS.

[Visceral leishmaniasis in Argentina. Cases notification and distribution of vectors (2006-2012)]. / Leishmaniasis visceral en la Argentina. Notificación y situación vectorial (2006-2012).

Visceral leishmaniasis (VL) is a notifiable disease in Argentina. Every new case diagnosed must be reported to the National Health Surveillance System. In the period 2006-2012, a total of 103 cases have been notified in four provinces: Entre Rios, Santa Fe, Misiones and Santiago del Estero. Misiones has the largest amount of cases: a total of 80, detected in 15 towns from May 2006 to July 2012. The highest incidence is observed in children (less than 15 years of age). In 2004 the vector Lutzomyia longipalpis was detected for the first time in Formosa Province. Cases of human and canine VL, as well as the presence of the canine vector were reported in 2006 in the province of Misiones, and in 2008-2009 in the province of Corrientes. In Santiago del Estero cases of human and canine VL (2008) were possibly associated with secondary vectors. In 2010 Lu longipalpis was found in Entre Rios, showing its dispersal to the south. Between January and April 2011 a systematic search of the VL vector was carried out in 13 towns, in Entre Ríos, Santa Fe and Santiago del Estero Provinces (275 traps/night). The colonization of the vector Lu longipalpis was proved in Chajarí town (Entre Rios), but not in Santiago del Estero Province, where Migonemyia migonei appears as a putative LV vector.

Tympanoplasty in the Setting of Complex Middle Ear Pathology: A Systematic Review.

OBJECTIVE: To assess the prognostic factors for anatomic and hearing success after tympanoplasty in the setting of complex middle ear pathology. METHODS: A systematic review was performed in January 2022. English-language articles describing outcome data for tympanoplasty repair variables including underlying pathology, perforation location, smoking status, graft technique, reconstruction material, anatomic success, and hearing success were extracted. Articles were included when tympanosclerosis, retraction pockets, adhesions, cholesteatoma, chronic suppurative otitis media, anterior perforations, and smoking were included. Underlying pathology, perforation location, smoking status, graft technique, reconstruction material, anatomic success, and hearing success were extracted. Any factors analyzed as potential indicators of success were sought out. RESULTS: Data sources included PubMed, OVID, Cochrane, Web of Science, Scopus, and manual search of bibliographies. Ninety-three articles met final criteria, which accounted for 6685 patients. Fifty articles presented data on both anatomic and hearing outcomes, 32 articles presented data on anatomic outcomes only, and 11 articles presented data on hearing outcomes only. This systematic review found that adhesions and tympanosclerosis were prognostic factors for poorer hearing. Additionally, smoking and tympanosclerosis may be predictive of anatomic failure; however, the significance of this finding was mixed in included studies. This analysis is significantly limited by both the heterogeneity within the patients and the lack of controls. CONCLUSION: Adhesions and tympanosclerosis were prognostic factors for poorer hearing. Clearly documented methods and outcomes for the included pathologies could lead to more definitive conclusions regarding prognostic factors for success. LEVEL OF EVIDENCE: 3B.

Severe Hyponatremia in the Setting of COVID-19-Associated Syndrome of Inappropriate Antidiuretic Hormone: A Case Report.

The COVID-19 pandemic has resulted in significant worldwide morbidity and mortality. One of the less studied clinical manifestations is Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) associated with COVID-19 pneumonia. We present a single case of COVID-19 pneumonia-associated SIADH in a 71-year-old male with a history of alcohol use disorder. This case highlights the importance of full diagnostic workup of the underlying cause of hyponatremia to avoid significant morbidity.

Comparison of Outcomes of Surgery Versus Implantable Device for the Treatment of Hearing Loss Associated With Congenital Aural Atresia: A Systematic Review and Meta-Analysis.

OBJECTIVE: To compare audiometric outcomes, complications, and revisions required for implantable bone-conduction devices (BCDs) versus atresia surgery for the treatment of hearing loss associated with congenital aural atresia. DATABASES REVIEWED: PubMed, Scopus, CINAHL. METHODS: Databases were searched for English articles from inception to July 1, 2022, for studies reporting audiometric outcomes or complications for either BCDs or atresia surgery for the treatment of congenital aural atresia. Main outcome measures included pure-tone audiometry, air-bone gap, speech reception threshold, associated complications, and rates of revision for each treatment option. RESULTS: We identified 973 abstracts, of which 89 were selected for data extraction and analysis. A total of 2,611 patients were included, 1,901 in the atresia surgery group and 710 in the BCDs group. A meta-analysis of single means was conducted for age and audiometric outcomes, and a meta-analysis of proportions was conducted for complications and revisions. The average short-term improvement in pure-tone audiometry for the BCDs group was 34.4 ± 1.6 dB compared with 22.4 ± 1.5 dB for the atresia surgery group, representing a significant difference (12.0 dB; 95% confidence interval, 11.9-12.2; p < 0.0001). A smaller proportion of complications were reported in the devices group (16.9%) compared with the atresia surgery group (45.7%). In addition, a smaller proportion of cases in the devices group required some degree of revision (17.8%) compared with the atresia surgery group (23.0%). CONCLUSIONS: This study demonstrates that implantable BCDs have significantly better audiometric outcomes as well as a lower rate of complications and revisions required compared with atresia surgery.

The impact of race on olfaction: A systematic review and meta-analysis.

BACKGROUND: Many studies have identified a higher degree of Olfactory Dysfunction (OD) in Black patients compared to White patients. This study aims to analyze olfactory outcomes in different races. METHODS: The PubMed, Scopus, and CINAHL databases were searched from inception to September 5, 2022, for English-language articles documenting self-reported and psychophysical OD stratified by race. A meta-analysis of proportions, comparison of weighted proportions, and comparison of means were performed in MedCalc 20.218. In the quantitative analysis, 79,297 patients were included, comprising 79.3% Whites, 16.1% Blacks, and 4.6% Hispanics. RESULTS: A total of 14 studies were meta-analyzed. The prevalence of self-reported OD in Hispanic, White, and Black patients was 19.5% (95% CI, 16.6% to 22.6%), 17.2% (95% CI, 10.5% to 25.0%), and 13.9% (95% CI, 9.3% to 19.2%), respectively (p < 0.0007). The prevalence of psychophysical OD in Black, White, and Hispanic patients was 30.3% (95% CI, 24.2% to 36.9%), 24.2% (95% CI, 20.1% to 28.5%), and 18.4% (95% CI, 16.3% to 20.7%), respectively (p < 0.0001). Blacks reported a greater extent of unrecognized OD compared to Whites, with a difference of 16.5% (95% CI, 15.0% to 17.9%) versus 5.8% (95% CI, 3.4% to 8.0%), respectively (p < 0.0001). Hispanic rates of self-reported OD and psychophysical OD were not statistically different. CONCLUSIONS: Our findings suggest that Blacks have the highest rate of psychophysical OD and are more likely to underreport their awareness compared to Whites.

The Impact of Surgical Indication on Posttonsillectomy Hemorrhage: A Systematic Review and Meta-Analysis.

OBJECTIVE: To investigate the impact of the surgical indication on posttonsillectomy bleed rates. DATA SOURCES: PubMed, Scopus, CINAHL. REVIEW METHODS: A systematic review was performed searching for articles published from the date of inception to July 6, 2022. English language articles describing posttonsillectomy hemorrhage rates in pediatric patients (age ≤ 18) stratified by indication were selected for inclusion. A meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. All studies were assessed for risk of bias. RESULTS: A total of 72 articles with 173,970 patients were selected for inclusion. The most common indications were chronic/recurrent tonsillitis (CT/RT), obstructive sleep apnea/sleep-disordered breathing (OSA/SDB), and adenotonsillar hypertrophy (ATH). Posttonsillectomy hemorrhage rates for CT/RT, OSA/SDB, and ATH were 3.57%, 3.69%, and 2.72%, respectively. Patients operated on for a combination of CT/RT and OSA/SDB had a bleed rate of 5.99% which was significantly higher than those operated on for CT/RT alone (Δ2.42%, p = .0006), OSA/SDB alone (Δ2.30%, p = .0016), and ATH alone (Δ3.27%, p < .0001). Additionally, those operated on for a combination of ATH and CT/RT had a hemorrhage rate of 6.93%, significantly higher than those operated on for CT/RT alone (Δ3.36%, p = .0003), OSA/SDB alone (Δ3.01%, p = .0014), and ATH alone (Δ3.98%, p < .0001). CONCLUSION: Patients operated on for multiple indications had significantly higher rates of posttonsillectomy hemorrhage than those operated on for a single surgical indication. Better documentation of patients with multiple indications would help further characterize the magnitude of the compounding effect described here.

Association between Social Determinants of Health and Allergic Fungal Rhinosinusitis: A Systematic Review and Meta-analysis.

OBJECTIVE: Some previous studies have shown an increased prevalence of allergic fungal rhinosinusitis (AFRS) among young, black patients with poor access to health care; however, results have been mixed. The purpose of this study was to investigate the relationship between social determinants of health and AFRS. DATA SOURCES: PubMed, Scopus, CINAHL. REVIEW METHODS: A systematic review was performed searching for articles published from date of inception to September 29, 2022. English language articles describing the relationship   between social determinants of health (i.e., race, insurance status) and AFRS as compared to chronic rhinosinusitis (CRS) were selected for inclusion. A Meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. RESULTS: A total of 21 articles with 1605 patients were selected for inclusion. The proportion of   black patients among AFRS, chronic rhinosinusitis with nasal polyps (CRSwNP), and chronic rhinosinusitis without nasal polyps (CRSsNP) groups was 58.0% [45.3%-70.1%], 23.8% [14.1%-35.2%], and 13.0% [5.1%-24.0%], respectively. This was significantly higher among the AFRS population compared to both the CRSwNP population (Δ34.2% [28.4%-39.6%], p < .0001) and the CRSsNP population (Δ44.9% [38.4%-50.6%], p < .0001). The proportion of patients who were either uninsured or covered by Medicaid among the AFRS, CRSwNP, and CRSsNP populations was 31.5% [25.4%-38.1%], 8.6% [0.7%-23.8%], and 5.0% [0.3%-14.8%], respectively. This was significantly higher among the AFRS group than the CRSwNP group (Δ22.9% [15.3%-31.1%], p < .0001) and the CRSsNP group (Δ26.5% [19.1%-33.4%], p < .0001). CONCLUSION: This study confirms that AFRS patients are more likely to be Black and either uninsured or on subsidized insurance than their CRS counterparts.

Functional electrical stimulation therapy controlled by a P300-based brain-computer interface, as a therapeutic alternative for upper limb motor function recovery in chronic post-stroke patients. A non-randomized pilot study.

Introduction: Up to 80% of post-stroke patients present upper-limb motor impairment (ULMI), causing functional limitations in daily activities and loss of independence. UMLI is seldom fully recovered after stroke when using conventional therapeutic approaches. Functional Electrical Stimulation Therapy (FEST) controlled by Brain-Computer Interface (BCI) is an alternative that may induce neuroplastic changes, even in chronic post-stroke patients. The purpose of this work was to evaluate the effects of a P300-based BCI-controlled FEST intervention, for ULMI recovery of chronic post-stroke patients. Methods: A non-randomized pilot study was conducted, including 14 patients divided into 2 groups: BCI-FEST, and Conventional Therapy. Assessments of Upper limb functionality with Action Research Arm Test (ARAT), performance impairment with Fugl-Meyer assessment (FMA), Functional Independence Measure (FIM) and spasticity through Modified Ashworth Scale (MAS) were performed at baseline and after carrying out 20 therapy sessions, and the obtained scores compared using Chi square and Mann-Whitney U statistical tests (𝛼 = 0.05). Results: After training, we found statistically significant differences between groups for FMA (p = 0.012), ARAT (p < 0.001), and FIM (p = 0.025) scales. Discussion: It has been shown that FEST controlled by a P300-based BCI, may be more effective than conventional therapy to improve ULMI after stroke, regardless of chronicity. Conclusion: The results of the proposed BCI-FEST intervention are promising, even for the most chronic post-stroke patients often relegated from novel interventions, whose expected recovery with conventional therapy is very low. It is necessary to carry out a randomized controlled trial in the future with a larger sample of patients.

Personalized protocol and scoring scale for functional electrical stimulation of the hand: A pilot feasibility study.

BACKGROUND: Complex personalized Functional Electrical Stimulation (FES) protocols for calibrating parameters and electrode positioning have been proposed, most being time-consuming or technically cumbersome for clinical settings. Therefore, there is a need for new personalized FES protocols that generate comfortable, functional hand movements, while being feasible for clinical translation. OBJECTIVE: To develop a personalized FES protocol, comprising electrode placement and parameter selection, to generate hand opening (HO), power grasp (PW) and precision grip (PG) movements, and compare in a pilot feasibility study its performance to a non-personalized protocol based on standard FES guidelines. METHODS: Two FES protocols, one personalized (P1) and one non-personalized (P2), were used to produce hand movements in twenty-three healthy participants. FES-induced movements were assessed with a new scoring scale which comprises items for selectivity, functionality, and comfort. RESULTS: Higher FES-HSS scores were obtained with P1 for all movements: HO (p= 0.00013), PW (p= 0.00007), PG (p= 0.00460). Electrode placement time was significantly shorter for P2 (p= 0.00003). Comfort scores were similar for both protocols. CONCLUSIONS: The personalized protocol for electrode placement and parameter selection enabled functional FES-induced hand movements and presented advantages over a non-personalized protocol. This protocol warrants further investigation to confirm its suitability for developing upper-limb rehabilitation interventions with clinical translational potential.
