Are We Speaking the Same Language? A Systematic Review on the Use of Consistent Language in Reporting Fat Necrosis in Autologous Fat Grafting of the Breast. Aesthetic Plast Surg 2024; 48:1403-1416. [PMID: 37670050 DOI: 10.1007/s00266-023-03568-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Accepted: 07/17/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Autologous fat grafting is a widely adopted approach to optimize outcomes in breast reconstruction and augmentation. Although fat necrosis is a well-known consequence of autologous fat grafting, it remains inconsistently defined in the literature. In late 2014, the Food and Drug Administration released a draft guidance to restrict future autologous fat grafting-a statement that was permissively modified in late 2017. In the context of evolving guidelines and autologous fat grafting outcome data, the language and descriptions of fat necrosis are inconsistent in the literature. METHODS Five databases were queried for studies reporting fat necrosis following autologous fat grafting for breast reconstruction or augmentation from inception to August 11, 2022. Studies were temporally stratified according to released FDA guidelines: pre-2015, 2015-2017, and 2018-2022. RESULTS Sixty-one articles met inclusion criteria. Prior to 2015, 6 of 21 studies (28.6%) offered clear definitions of fat necrosis. In contrast, the 2015-2017 period demonstrated an absence of clear fat necrosis definitions (0/13 studies, p = 0.03). Though the 2018-2022 period exhibited a rise in annual publications compared with the pre-2015 period (5.4 vs. 1.9, respectively, p = 0.04), this was not matched by a rise in clear fat necrosis reporting (14.8% studies, p = 0.45). Across all periods, only 16.4% of articles offered clear definitions, which exhibited wide heterogeneity. CONCLUSION Despite the increasing popularity of autologous fat grafting, fat necrosis remains inconsistently defined and described, especially in the context of changing FDA guidelines. This limits the reliable interpretation and application of the current literature reporting fat necrosis outcomes.

Olfactory Dysfunction Following Moderate to Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis. Neuropsychol Rev 2023; 33:717-732. [PMID: 36070126 PMCID: PMC10040093 DOI: 10.1007/s11065-022-09563-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 05/30/2022] [Accepted: 07/11/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVE Reports of smell loss following traumatic brain injury (TBI) are a well-documented but understudied phenomenon. Given the broad consequences of olfactory loss, we characterized psychophysical olfactory dysfunction in individuals with moderate to severe TBI using systematic review and meta-analytic methods. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol, five databases (PubMed, EMBASE, Cochrane Library, Web of Science, Scopus) were reviewed for studies investigating olfactory dysfunction in persons with moderate to severe TBI. Of the 5,223 studies reviewed, 19 met our inclusion criteria for the systematic review and 11 met inclusion criteria for meta-analysis. We calculated effect sizes (Hedges' g) to characterize the degree of olfactory dysfunction between patients with moderate to severe TBI and controls. RESULTS A total of 951 moderate-severe TBI patients from 19 studies were included in the systematic review, which largely demonstrated poorer olfactory psychophysical performances in this patient population. Meta-analysis demonstrated a large effect size for olfactory dysfunction in moderate-severe TBI relative to healthy controls (g=-2.43, 95%CI: -3.16 < δ<-1.69). The magnitude of the effect was moderated by age and patient sex, with larger effect sizes associated with older age (following exclusion of a pediatric population) and larger compositions of women in the patient group. CONCLUSION Moderate to severe TBI is associated with prominent olfactory dysfunction. Significant research gaps remain regarding the mechanism, recovery and natural history of olfactory dysfunction following moderate to severe TBI, which has significant clinical implications for the identification and treatment for those with post-traumatic olfactory dysfunction.

Abstract
INTRODUCTION Hearing loss has been shown to be associated with both negative health outcomes and low socioeconomic position, including lower income. Despite this, a thorough review of the existing literature on this relationship has not yet been performed. OBJECTIVES To evaluate available literature on the possible association between income and adult-onset hearing loss. DESIGN A search was conducted in eight databases for all relevant literature using terms focused on hearing loss and income. Studies reporting the presence or absence of an association between income and hearing loss, full-text English-language access, and a predominantly adult population (≥18 years old) were eligible. The Newcastle-Ottawa Quality Assessment Scale was used to assess risk of bias. RESULTS The initial literature search yielded 2994 references with three additional sources added through citation searching. After duplicate removal, 2355 articles underwent title and abstract screening. This yielded 161 articles eligible for full-text review resulting in 46 articles that were included in qualitative synthesis. Of the included studies, 41 of 46 articles found an association between income and adult-onset hearing loss. Due to heterogeneity among study designs, a meta-analysis was not performed. CONCLUSIONS The available literature consistently supports an association between income and adult-onset hearing loss but is limited entirely to cross-sectional studies with the directionality remaining unknown. An aging population and the negative health outcomes associated with hearing loss, emphasize the importance of understanding and addressing the role of social determinants of health in the prevention and management of hearing loss.

Sex and Race Representation in Temporal Bone Histopathology Studies in the United States: A Systematic Review. Ear Hear 2023; 44:661-669. [PMID: 36763469 PMCID: PMC10331314 DOI: 10.1097/aud.0000000000001340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/11/2023]
Abstract
OBJECTIVES The author's objective was to evaluate sex and race representation in temporal bone histopathology studies. DESIGN PubMed, Embase, Cochrane, Web of Science, and Scopus were searched for studies written in English examining temporal bone histopathology specimens from U.S.-based institutions from January 1, 1947, to September 1, 2021. Two authors then performed "snowballing" by reviewing references from the initial search and included the studies that fulfilled the inclusion criteria. For each study, the following information was collected: publication details, study design, funding, institution from where temporal bone specimens were procured, number of study specimens, and donor demographical information. RESULTS The authors found that out of 300 studies, 166 (55%) report sex while only 15 (5%) reported race information. Over the past 70 years, the ratio of studies reporting sex to those that do not has increased from 1.00 to 2.19 and the number of female temporal bone histopathology subjects relative to male has increased from 0.67 to 0.75. Over 90% of studies that do report this information feature participant racial compositions that do not reflect the diversity of the U.S. population. CONCLUSIONS Studies of temporal bone histopathology often do not report participant sex or race. The reporting of participant sex and the inclusion of specimens from female donors have both increased over time. However, temporal bone histopathology study cohorts are not representative of the racial diversity of the U.S. population. The otolaryngology community must strive to build temporal bone histopathology libraries that are representative of the diverse U.S. population.

Embolization in Juvenile Nasopharyngeal Angiofibroma Surgery: A Systematic Review and Meta-Analysis. Laryngoscope 2023. [PMID: 36789781 DOI: 10.1002/lary.30616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 01/18/2023] [Accepted: 01/25/2023] [Indexed: 02/16/2023]
Abstract
OBJECTIVE To compare outcomes of juvenile nasopharyngeal angiofibroma (JNA) resection between embolized and non-embolized cohorts, and between transarterial embolization (TAE) and direct puncture embolization (DPE). DATA SOURCES Per PRISMA guidelines, PubMed, Embase, Web of Science, Scopus, and Cochrane databases were searched for publications prior to or in 2021. MATERIALS AND METHODS Original English manuscripts investigating the resection of JNA with and without preoperative embolization were included. Embolization type, recurrence rate, complication rates, blood loss, and transfusions were extracted. Risk of bias was assessed by the Risk of Bias in Non-randomized Studies-of Interventions method. RESULTS There were 61 studies with 917 patients included. Preoperative embolization was performed in 79.3% of patients. Of those embolized, 75.8% (N = 551) underwent TAE and 15.8% (N = 115) underwent DPE. JNA recurrence in embolized patients was lower than in non-embolized patients (9.3% vs. 14.4%; odds ratio [OR]: 0.61, 95% confidence interval [CI]: 0.35, 1.06). DPE resulted in lower rates of disease recurrence (0% vs. 9.5%; OR: 0.066, 95% CI: 0.016, 0.272) and complications (1.8% vs. 21.9%; OR: 0.07, 95% CI: 0.02, 0.3) than TAE. A random effects Bayesian model was performed to analyze the difference in mean blood loss in 6 studies that included both embolized and non-embolized patients. This analysis showed a mean reduction in blood loss of 798 mL in the embolized group. CONCLUSIONS We found embolization decreases blood loss in JNA resection. DPE led to improved recurrence and complication rates when compared to TAE, but future prospective studies are needed to further evaluate which embolization technique can optimize outcomes in JNA. LEVEL OF EVIDENCE NA Laryngoscope, 2023.

Cast selection and non-union rates for acute scaphoid fractures treated conservatively: a systematic review and meta-analysis. J Plast Surg Hand Surg 2023; 57:16-21. [PMID: 35034563 DOI: 10.1080/2000656x.2021.2024439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/19/2022]
Abstract
Cast selection for conservatively treated acute scaphoid fractures remains controversial. Cast options include short arm versus long arm, and those that include the thumb or leave it free. We sought to investigate the role of how cast choice affects nonunion rates after conservative management of scaphoid fractures. We searched PubMed, Embase, and Google Scholar from inception through July 14, 2020, according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. We extracted information of interest, including cast type, and non-union rates at the end of the treatment period. We then performed a meta-analysis using the random-effects model. We identified seven relevant studies. Non-union was observed in 15 out of 156 (9.6%) with short-arm cast and 13 out of the 124 (10.5%) with long-arm cast (OR = 0.79, 95% CI [0.19, 3.26], p = 0.74). Non-union was observed in 18 out of 174 (10.3%) with thumb immobilization cast and 18 out of the 179 (10.1%) without thumb immobilization (OR = 0.97, 95% CI [0.49, 1.94], p = 0.69). In our study, short arm casting was proven non-inferior to long arm casting. Similarly, casts without thumb immobilization were equally as effective as casts with thumb immobilization in terms of non-union rates for acute scaphoid fractures treated non-operatively.

Radiographic imaging modalities for perinatal brachial plexus palsy: a systematic review. Childs Nerv Syst 2022; 38:1241-1258. [PMID: 35536348 DOI: 10.1007/s00381-022-05538-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 04/20/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE Perinatal brachial plexus palsy (PBPP) has a wide spectrum of clinical symptoms that can range from incomplete paresis of the affected extremity to flaccid arm paralysis. Although there is a high rate of spontaneous recovery within the first two years of life, it remains challenging to determine which patients will benefit most from surgical intervention. The diagnostic and predictive use of various imaging modalities has been described in the literature, but there is little consensus on approach or algorithm. The anatomic, pathophysiological, and neurodevelopmental characteristics of the neonatal and infant patient population affected by PBPP necessitate thoughtful consideration prior to selecting an imaging modality. METHODS A systematic review was conducted using six databases. Two reviewers independently screened articles published through October 2021. RESULTS Literature search produced 10,329 publications, and 22 articles were included in the final analysis. These studies included 479 patients. Mean age at time of imaging ranged from 2.1 to 12.8 months and investigated imaging modalities included MRI (18 studies), ultrasound (4 studies), CT myelography (4 studies), and X-ray myelography (1 study). Imaging outcomes were compared against surgical findings (16 studies) or clinical examination (6 studies), and 87.5% of patients underwent surgery. CONCLUSION This systematic review addresses the relative strengths and challenges of common radiologic imaging options. MRI is the most sensitive and specific for identifying preganglionic nerve injuries such as pseudomeningoceles and rootlet avulsion, the latter of which has the poorest prognosis in this patient population and often dictates the need for surgical intervention.

Environmental air pollution and chronic rhinosinusitis: A systematic review. Laryngoscope Investig Otolaryngol 2022; 7:349-360. [PMID: 35434330 PMCID: PMC9008184 DOI: 10.1002/lio2.774] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 02/25/2022] [Accepted: 03/01/2022] [Indexed: 11/07/2022] Open
Abstract
Objective Chronic rhinosinusitis (CRS) is a highly prevalent and burdensome disease. The pathophysiology is not fully elucidated, but environmental pollutants have been suggested to impact the inflammatory component of the disease process. This review aims to summarize the role of environmental pollution in CRS onset and disease severity. Methods A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases were queried in August 2021. Original articles reporting on air pollution exposure in CRS were included. Other forms of sinonasal disease were excluded. Results Literature search produced 11,983 articles, of which 10 met inclusion criteria. Outcomes evaluated included incidence/prevalence, disease severity, quality of life, and histopathologic/microbial changes. Air pollutant exposure was associated with higher odds of CRS, particularly with particulate matter (PM) exposure. Increasing air pollution exposure was also associated with worsened disease severity and detectable histopathologic changes. Impact on quality of life was less clear. Conclusion Air pollution (particularly PM) is correlated with CRS incidence/prevalence and disease severity, with evidence of histopathologic changes in CRS tissue samples. Further research is warranted to better understand the mechanisms by which air pollution components may cause CRS and type 2 inflammation. Level of Evidence 3a Recent evidence suggests a role for air pollution in the onset and severity of CRS, most notably with relation to PM2.5 exposure. This systematic review supports previous in vitro and in vivo models of pollution in CRS. This study further adds to the existing body of literature demonstrating the many negative health impacts of exposure to air pollution, including impacts on upper airway disease, lower airway disease, cardiac disease, and overall morbidity and mortality.

Abstract
The Johns Hopkins Otologic Research Laboratory was founded in 1924 as the first human temporal bone laboratory within the United States. To better understand the contributions of the Johns Hopkins Otologic Research Laboratory to our understanding of presbycusis, we consulted with a medical librarian and archivist to search the Alan Mason Chesney Medical Archives, PubMed, JSTOR, and Johns Hopkins Bulletin for published and unpublished works from the lab. Between 1924 and 1938, Samuel J. Crowe, the Chairman of Otolaryngology, and anatomist Stacy R. Guild amassed a collection of ∼1,800 temporal bones. This collection allowed for an unprecedented period of discovery related to otologic disease. They combined hearing thresholds measured by the recently invented audiometer with new techniques for temporal bone decalcification, sectioning, and staining, and a method for the graphic reconstruction of the cochlea. Crowe and Guild used this unique opportunity to correlate otopathology with hearing and to make the first detailed descriptions of the otopathology of presbycusis. In 1931 and 1934, they observed spiral ganglion neuron and outer hair cell loss in the basal turn of the cochlea in individuals with high-frequency hearing loss. These were the first studies to reveal that stria vascularis degeneration and middle ear pathology were not the most common causes for high-frequency hearing loss. Aside from revealing the primary driving factors of presbycusis, this work provided insight into the tonotopic organization of the cochlea. After initially being recruited to help raise money for the laboratory, medical illustrator Max Brödel used the vertical histologic cross-sections of the cochlea to produce illustrations of the ear. The decision to produce histologic sections in the plane of the superior semicircular canal likely influenced Brödel's illustrations that share a similar orientation and would later become widely circulated. Significant contributions from the Otologic Research Laboratory were also made by Mary Hardy, D.Sc., a woman who has previously received little recognition for her work. The sectioning of temporal bones was stopped in 1938 due to World War II, but much of Crowe's and Guild's work continued into the 1940s until a rift between the two resulted in the temporary closure of the laboratory in 1949. Nearly 100 years after its founding, discoveries from the Johns Hopkins Otologic Research Laboratory remain relevant and emphasize the importance of continued human temporal bone research to improve our understanding and treatment of otologic disease.

Abstract
Importance Neurological and neuropsychiatric symptoms that persist or develop three months after the onset of COVID-19 pose a significant threat to the global healthcare system. These symptoms are yet to be synthesized and quantified via meta-analysis. Objective To determine the prevalence of neurological and neuropsychiatric symptoms reported 12 weeks (3 months) or more after acute COVID-19 onset in adults. Data sources A systematic search of PubMed, EMBASE, Web of Science, Google Scholar and Scopus was conducted for studies published between January 1st, 2020 and August 1st, 2021. The systematic review was guided by Preferred Reporting Items for Systematic Review and Meta-Analyses. Study selection Studies were included if the length of follow-up satisfied the National Institute for Healthcare Excellence (NICE) definition of post-COVID-19 syndrome (symptoms that develop or persist ≥3 months after the onset of COVID-19). Additional criteria included the reporting of neurological or neuropsychiatric symptoms in individuals with COVID-19. Data extraction and synthesis Two authors independently extracted data on patient characteristics, hospital and/or ICU admission, acute-phase COVID-19 symptoms, length of follow-up, and neurological and neuropsychiatric symptoms. Main outcome(s) and measure(s) The primary outcome was the prevalence of neurological and neuropsychiatric symptoms reported ≥3 months post onset of COVID-19. We also compared post-COVID-19 syndrome in hospitalised vs. non-hospitalised patients, with vs. without ICU admission during the acute phase of infection, and with mid-term (3 to 6 months) and long-term (>6 months) follow-up. Results Of 1458 articles, 18 studies, encompassing a total of 10,530 patients, were analysed. Overall prevalence for neurological post-COVID-19 symptoms were: fatigue (37%, 95% CI: 25%–48%), brain fog (32%, 10%–54%), memory issues (28%, 22%–35%), attention disorder (22%, 7%–36%), myalgia (17%, 9%–25%), anosmia (12%, 8%–16%), dysgeusia (10%, 6%–14%) and headache (15%, 4%–26%). Neuropsychiatric conditions included sleep disturbances (31%, 19%–42%), anxiety (23%, 14%–32%) and depression (17%, 10%–24%). Neuropsychiatric symptoms substantially increased in prevalence between mid- and long-term follow-up. Compared to non-hospitalised patients, patients hospitalised for acute COVID-19 had reduced frequency of anosmia, anxiety, depression, dysgeusia, fatigue, headache, myalgia, and sleep disturbance at three (or more) months post-infection. Cohorts with >20% of patients admitted to the ICU during acute COVID-19 experienced higher prevalence of fatigue, anxiety, depression, and sleep disturbances than cohorts with <20% of ICU admission. Conclusions and relevance Fatigue, cognitive dysfunction (brain fog, memory issues, attention disorder) and sleep disturbances appear to be key features of post-COVID-19 syndrome. Psychiatric manifestations (sleep disturbances, anxiety, and depression) are common and increase significantly in prevalence over time. Randomised controlled trials are necessary to develop intervention strategy to reduce disease burden.

Taste receptors in CRS, what is the evidence?: a systematic review. Int Forum Allergy Rhinol 2021; 12:917-934. [PMID: 34913601 DOI: 10.1002/alr.22938] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/13/2021] [Accepted: 12/06/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Bitter (T2Rs) and sweet (T1Rs) taste receptors are involved in the innate immune response of the sinonasal cavity and associated with chronic rhinosinusitis (CRS). Growing evidence suggests extraoral taste receptors as relevant biomarkers, but current understanding is incomplete. This systematic review synthesizes current evidence of extraoral taste receptors in CRS. METHODS PubMed, Embase, Cochrane, Web of Science, and Scopus were reviewed in accordance with Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines and included studies of genotypic and phenotypic T2R/T1R receptor status in CRS patients. RESULTS Twenty-two studies with 3,845 patients were included. Seventeen studies evaluated genotype and 10 evaluated taste phenotypes. Four of six studies examining the haplotype distribution of the T2R, TAS2R38, demonstrated increased AVI/AVI haplotype ("non-taster") frequency in CRS. Meanwhile, two studies demonstrated decreased bitter sensitivity in CRS with nasal polyposis (CRSwNP) while three other studies reported decreased bitter sensitivity only in CRS without nasal polyposis (CRSsNP). Findings regarding sweet sensitivity were mixed. Three studies with cystic fibrosis patients (n=1,393) were included. Studies investigating the association between clinical outcomes and TAS2R38 alleles were limited, but the nonfunctional combination of AVI/AVI was associated with increased utilization of sinus surgery and, in CRSsNP patients, with poorer improvement of symptoms postoperatively. CONCLUSIONS Both genotypic and phenotypic assessments of T2Rs suggest a potential association with CRS, particularly CRSsNP. However, limited evidence and mixed conclusions cloud the role of T2Rs in CRS. Future investigations should aim to increase diverse populations, broaden institutional diversity, examine T1Rs, and utilize uniform assessments. This article is protected by copyright.

Abstract
Accurate models are fundamental tools for risk-stratification, therapy guidance, resource-allocation, and comparative-effectiveness research. Enhanced recovery after surgery (ERAS) protocols increase early post-operative recovery rates in surgical patients. The uniqueness of burn injuries and their post-operative care requires developing a specialized protocol, enhanced recovery after burn surgery (ERABS). To develop such a protocol, we need to examine post-operative practices, like time-to-ambulation, and their effect on post-operative complications. We evaluated evidence supporting complications such as graft loss, thrombolytic events, and pain, relating to the timing of post-surgical ambulation. A literature search on early-ambulation and skin-grafting was performed by two independent researchers. No time limit was set for publication dates. Relevant studies relating to ambulation of adult burn patients (>18 years of age) and their post-surgical outcomes were captured using search terms. Of the 888 studies retrieved from the query, 11 were used for review and meta-analysis. Our review revealed minimal evidence exists relating to thromboembolic events and time-to-ambulation in post-operative burn patients. The evidence that does exist found no significant difference in the number of events between early- and late-ambulation groups. Increased pain during rest and ambulation was shown in patients with delayed ambulation after five or more days. One study found an increased infection rate in late-ambulatory patients. The primary conclusion from this review is that further studies must be performed examining the correlation of thromboembolic events and infection rates with post-operative time-to-ambulation. Based on current literature, early ambulation should be included as part of a future model of ERABS.

Predictive value of the Eustachian Tube Dysfunction Questionnaire-7 for identifying obstructive Eustachian tube dysfunction: A systematic review. Laryngoscope Investig Otolaryngol 2021; 6:844-851. [PMID: 34401511 PMCID: PMC8356874 DOI: 10.1002/lio2.606] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 05/26/2021] [Accepted: 06/10/2021] [Indexed: 01/01/2023] Open
Abstract
OBJECTIVE To perform a systematic review to determine if a total score of ≥14.5 (mean score ≥ 2.1) on the ETDQ-7 accurately identifies patients with obstructive Eustachian tube dysfunction (OETD) on impedance tympanometry (peak compliance <0.2 mL or middle ear pressure of -100 daPa) or other objective measures of OETD. METHODS A systematic review without a meta-analysis was performed of studies in four electronic databases (Pubmed, Embase, Web of Science, and Scopus) that used the ETDQ-7 and at least one objective measure of OETD. RESULTS Six-hundred and fifty-two studies were identified in the initial literature search. Abstracts from 337 studies were screened, followed by full-text review of 61 studies, and qualitative synthesis of 12 studies. Tympanometry was used as an objective measure in ten studies. Eight of the 12 included studies had patient cohort selection bias. Eight studies administered the ETDQ-7 in cohorts of patients with or without OETD, already confirmed on tympanometry, and found a sensitivity of 91%-100% and specificity of 67%-100%. Four studies administered the ETDQ-7 to patients who had not previously undergone objective testing and found a sensitivity of 49%-80% and specificity of 24%-78%. CONCLUSIONS The ETDQ-7 is an important patient-reported outcome measure. However, based upon existing literature, the ETDQ-7 appears limited as a diagnostic tool for OETD or as an objective measure of Eustachian tube function.

[PMID: 33953548 PMCID: PMC8092634 DOI: 10.2147/ppa.s296280] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 03/02/2021] [Indexed: 12/13/2022] Open
Abstract
PURPOSE The burden of cardiovascular diseases (CVD) is high in low- and middle-income countries (LMICs). Medications are integral to the management and control of CVD; however, suboptimal adherence impacts health outcomes. This systematic review aims to critically examine interventions targeted at improving medication adherence among persons with CVD in LMICs. METHODS In this systematic review, we searched online databases PubMed, Embase, and CINAHL for studies that evaluated a medication adherence intervention for CVD, reported adherence as an outcome measure, were conducted in LMICs and reported the strategy or tool used to measure adherence. We included articles published in English, available in full text, peer-reviewed, and published between 2010 and 2020. RESULTS We included 45 articles in this review. The majority of the studies implemented counseling and educational interventions led by nurses, pharmacists, or community health workers. Many of the studies delivered medication-taking reminders in the form of phone calls, text messages, short message services (SMS), and in-phone calendars. Multi-component interventions were more effective than unifocal interventions. Interventions involving technology, such as mobile phone calls, electronic pillboxes, and interactive phone SMS reminders, were more effective than generic reminders. The outcomes reported in the studies varied based on the complexity and combination of strategies. When interventions were implemented at both the patient level, such as reminders, and at the provider level, such as team-based care, the effect on medication adherence was larger. CONCLUSION In LMICs, medication adherence interventions among persons with CVD included a combination of patient education, reminders, fixed-dose combination therapy and team-based care approach were generally more effective than singular interventions. Among patients who had CVD, the medication adherence interventions were found to be moderately effective. Future studies focusing on improving medication adherence in LMICs should consider non-physician-led interventions and appropriately adapt the interventions to the local context.

Factors Associated with Mortality Following Burns Complicated by Necrotizing Skin and Soft Tissue Infections: A Systematic Review and Meta-analysis of Individual Participant Data. J Burn Care Res 2021; 43:163-188. [PMID: 33682000 DOI: 10.1093/jbcr/irab045] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/26/2022]
Abstract
We reviewed studies with individual participant data of patients who sustained burn injury and subsequently developed necrotizing skin and soft tissue infections (NSTI). Characteristics and managements were compared between patients who lived and patients who died to determine factors associated with mortality. Six databases (PubMed, EMBASE, Cochrane Library, Web of Science, Scopus and CINAHL) were searched. PRISMA-IPD guidelines were followed throughout the review. Eligible patients sustained a burn injury, treated in any setting, and diagnosed with a NSTI following burn injury. Comparisons were made between burned patients who lived "non-mortality" and burned patients who died "mortality" following NSTI using non-parametric univariate analyses. Fifty-eight studies with 78 patients were published from 1970 through 2019. Non-mortality resulted in 58 patients and mortality resulted in 20 patients. Patients with mortality had significantly greater median %TBSA burned (45%[IQR:44-64%] versus 35%[IQR:11-59%],p=0.033), more intubations (79% versus 43%,p=0.013), less debridements (83% versus 98%,p=0.039), less skin excisions (83% versus 98%,p=0.039), more complications (100% versus 50%,p<0.001), management at a burn center (100% versus 71%,p=0.008), underwent less flap surgeries (5% versus 35%,p=0.014), less graft survival (25% versus 86%,p<0.001), and less healed wounds (5% versus 95%,p<0.001), compared to patients with non-mortality, respectively. Non-mortality patients had more debridements, skin excised, systemic antimicrobials, skin graft survival, flaps, improvement following surgery and healed wounds compared to mortality patients. Mortality patients had greater %TBSA burned, intubations, management at a burn center and complications compared to non-mortality patients.

Outcomes of Adenotonsillectomy for Obstructive Sleep Apnea in Prader-Willi Syndrome: Systematic Review and Meta-analysis. Laryngoscope 2020; 131:898-906. [PMID: 33026674 DOI: 10.1002/lary.28922] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 05/27/2020] [Accepted: 06/18/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVES Prader-Willi syndrome (PWS) increases the risk of obstructive sleep apnea (OSA) due to obesity, hypotonia, and abnormal ventilatory responses. We evaluated post-adenotonsillectomy complications, polysomnography changes, and quality of life in children with OSA and PWS. STUDY DESIGN Systematic review and meta-analysis. METHODS We conducted a systematic review and meta-analysis by searching PubMed, Embase, Cochrane, Web of Science, and Scopus. Two researchers independently reviewed studies about adenotonsillectomy for OSA in patients <21 years with PWS. We extracted study design, patient numbers, age, complications, polysomnography, and quality of life. We pooled postoperative changes in apnea hypopnea index (AHI) for meta-analysis. We applied Methodological Index for Nonrandomized Studies (MINORS) criteria to assess study quality. RESULTS The initial search yielded 169 studies. We included 68 patients from eight studies with moderate to high risk of bias. Six studies reported on complications and 12 of 51 patients (24%) had at least one. Velopharyngeal insufficiency was the most commonly reported complication (7/51, 14%). We included seven studies in meta-analysis. Mean postoperative improvement in AHI was 7.7 (95% CI: 4.9-10.5). Postoperatively 20% (95% CI: 3%-43%) had resolution of OSA with AHI < 1.5 while 67% (95% CI: 50%-82%) had improvement from severe/moderate OSA to mild/resolved (AHI < 5). Two studies evaluated quality of life and demonstrated improvement. CONCLUSIONS Children with PWS undergoing adenotonsillectomy for OSA have a substantial risk of postoperative complications that may require additional interventions, especially velopharyngeal insufficiency. Despite improvements in polysomnography and quality of life, many patients had residual OSA. This information can be used to counsel families when considering OSA treatment options.

A Systematic Review and Meta-Analysis of Taste Dysfunction in Chronic Rhinosinusitis. Laryngoscope 2020; 131:482-489. [PMID: 32609889 DOI: 10.1002/lary.28827] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 04/29/2020] [Accepted: 05/19/2020] [Indexed: 01/27/2023]
Abstract
OBJECTIVES Patients with chronic rhinosinusitis (CRS) often describe alterations in sense of taste. These complaints have historically been attributed to olfactory dysfunction; however, there is evidence of direct, objective, gustatory disturbances in the setting of CRS that are not thoroughly characterized. This study sought to investigate and summarize gustatory dysfunction experienced by patients with CRS. METHODS PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases were reviewed following PRISMA guidelines. English language, original studies investigating objective taste in adult patients with CRS were included. A meta-analysis with inverse variance, random-effects model was performed. RESULTS Of 2750 studies screened, 11 articles with 471 unique patients were included. Patients with CRS exhibit worse gustatory function compared to healthy controls (standardized mean difference 0.94 [95% CI, 0.44-1.45]). Hypogeusia was identified in 32/95 (33.7%) patients from three studies that used methods with a validated definition of hypogeusia. Older age, male gender, and smoking history were associated with taste dysfunction, while objective gustatory and olfactory dysfunction were not correlated. Subjective taste and quality of life measures were also not associated with objective taste. The impact of sinus surgery on objective taste is unclear. CONCLUSION Approximately 34% of patients with CRS experience hypogeusia. Neither olfactory function nor subjective taste were associated with objective gustatory function. Given the substantial prevalence of taste dysfunction patients with CRS, there is significant potential for growth in understanding of pathogenesis, impact on quality of life, and potential treatment strategies of taste impairment in the CRS patient population.

Treatment of post-viral olfactory dysfunction: an evidence-based review with recommendations. Int Forum Allergy Rhinol 2020; 10:1065-1086. [PMID: 32567798 PMCID: PMC7361320 DOI: 10.1002/alr.22624] [Citation(s) in RCA: 66] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 05/07/2020] [Accepted: 05/12/2020] [Indexed: 12/29/2022]
Abstract
Background Post‐viral olfactory dysfunction (PVOD) is one of the most common causes of olfactory loss. Despite its prevalence, optimal treatment strategies remain unclear. This article provides a comprehensive review of PVOD treatment options and provides evidence‐based recommendations for their use. Methods A systematic review of the Medline, Embase, Cochrane, Web of Science, Scopus, and Google Scholar databases was completed according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. Studies with defined olfactory outcomes of patients treated for PVOD following medical, surgical, acupuncture, or olfactory training interventions were included. The Clinical Practice Guideline Development Manual and Conference on Guideline Standardization (COGS) instrument recommendations were followed in accordance with a previously described, rigorous, iterative process to create an evidence‐based review with recommendations. Results From 552 initial candidate articles, 36 studies with data for 2183 patients with PVOD were ultimately included. The most common method to assess olfactory outcomes was Sniffin’ Sticks. Broad treatment categories included: olfactory training, systemic steroids, topical therapies, a variety of heterogeneous non‐steroidal oral medications, and acupuncture. Conclusion Based on the available evidence, olfactory training is a recommendation for the treatment of PVOD. The use of short‐term systemic and/or topical steroids is an option in select patients after careful consideration of potential risks of oral steroids. Though some pharmacological investigations offer promising preliminary results for systemic and topical medications alike, a paucity of high‐quality studies limits the ability to make meaningful evidence‐based recommendations for the use of these therapies for the treatment of PVOD.

Abstract
BACKGROUND Early detection of vascular compromise following free flap microsurgical reconstruction is essential. This can lead to timely reoperations and flap salvage. Both arteries and veins are monitored postoperatively with implantable ultrasound Dopplers based on surgeon preference with no consensus as to which method is best. This systematic review and meta-analysis compared arterial to venous implantable Dopplers for postoperative monitoring of microsurgical free flap reconstruction. METHODS Five databases (MEDLINE via PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus) were systematically and independently searched. PRISMA and Cochrane guidelines were strictly followed. Clinical characteristics, donor and recipient sites, specific arterial or venous vessels, diagnostic data, outcomes, and complications were recorded. RESULTS The seven studies included in the meta-analysis were published from 1994 to 2018, with results from 38 of the possible 64 outcomes and complications queried. A total of 763 flaps with implantable Doppler probes on 527 arteries and 388 veins were included in the study. Compared to patients monitored with venous implantable Dopplers, arterial monitoring was associated with a risk of false-positives reduced by 74% (RR:0.26, 95% CI:0.12, 0.55, I2 = 40%, p = .0004) and risk of signal loss reduced by 63% (RR:0.37, 95% CI:0.24, 0.59, I2 = 26%, p < .0001). Patients being monitored with a venous implantable Doppler did not show significantly different sensitivities, specificities, true-positives, false-negatives, true-negatives, positive predictive values, negative predictive values, time to signal loss, take-backs, salvage rates, flap failures, flap failure rates, arterial, venous, vascular, and hematoma compromise compared to an arterial implantable Doppler. CONCLUSION These findings suggest arteries may be the best vessels to monitor when using an implantable Doppler following free flap microsurgical reconstruction. Caution is advised when interpreting these findings for clinical significance due to no significant differences in take-backs, SR, flap failures, and FFR.

Abstract
Introduction: Medicaid beneficiaries are a generally disadvantaged population with access to elective specialty services. We sought to better understand utilization of breast reconstruction by Medicaid beneficiaries.Methods: We systematically searched PubMed, Scopus, Web of Science, and CINAHL databases for studies comparing breast reconstruction rates by insurance type. We extracted the information of interest to qualitatively and quantitatively synthesize the results of the studies.Results: We identified seven eligible studies. Overall, the rates of breast reconstruction have increased across insurance groups. However, our results show that Medicaid beneficiaries were on average less likely to receive breast reconstruction in comparison to patients with private insurance. Although, Medicaid patients again were more likely to receive breast reconstruction in comparison to Medicare beneficiaries.Conclusion: There is wide disparity in reconstruction rates by insurance status. However, with continued increase in the adult Medicaid population due to widening eligibility expansion, disparities involving this vulnerable population should be examined for causes and solutions.

Abstract
Background Cutaneous manifestations of purpura fulminans (PF) present many challenges for clinicians and surgeons. In a state of septic shock complicated by limb ischemia, surgical interventions are necessary to control the pathological cascade and improve patient outcomes. The objective of this article was to report etiologies and surgical outcomes associated with cutaneous manifestations in adults. Methods This systematic review and meta-analysis compared 190 adult patients with etiologies, signs and symptoms, and surgical outcomes associated with cutaneous manifestations of PF. The PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases were systematically and independently searched. Patient and clinical characteristics, surgical interventions, outcomes, and complications were recorded. Results Seventy-nine studies were eligible for the systematic review, and 77 were eligible for meta-analysis using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) and Cochrane guidelines. A total of 71/190 (38%) cases reported surgical debridement. Fasciotomies were reported in 12/190 (6%) cases and 20 procedures. Amputations were reported in 154/190 (81%) cases. Reconstruction was reported in 45 cases. Skin grafts were applied in 31 cases. Flaps were used for reconstruction in 28 cases. Median (IQR) surgical procedures per patient were 4 (4, 5) procedures. Infectious organisms causing PF were 32% Neisseria meningitidis (n = 55) and 32% Streptococcus pneumonia (n = 55). Coagulase-negative Staphylococcus (95% confidence interval (CI)(8.2-177.9), p = 0.032), Haemophilus influenza (95%CI (7.2-133), p = 0.029), Streptococcus pneumonia (95% CI (13.3-75.9), p = 0.006), and West Nile Virus (95%CI (8.2-177.9), p = 0.032) were associated with significantly more extensive amputations compared to other organisms. Conclusion This systematic review and patient-level meta-analysis found the most common presentation of PF was septic shock from an infectious organism. Neisseria meningitidis and Streptococcus pneumonia were equally the most common organisms associated with PF. The majority of cases were not treated in a burn center. The most common surgeries were amputations, with below-the-knee-amputations being the most common procedure. Skin grafting was the most commonly performed reconstructive procedure. The most common complications were secondary infections. Organisms with significantly more extensive amputations were coagulase-negative Staphylococcus, Haemophilus influenza, Streptococcus pneumonia, and West Nile Virus. Interpretation of findings should be cautioned due to limited sample data.

Abstract
PURPOSE Use of antifibrinolytic drugs in craniofacial and orthognathic surgery seems quite promising and has strong advocates. However, supporting evidence is controversial and limited by a small sample of individual studies. We sought to systematically review and meta-analyze the available data regarding the role of preoperative or intraoperative antifibrinolytic drugs (eg, tranexamic acid, aprotinin, or aminocaproic acid) in craniofacial and orthognathic surgery. MATERIALS AND METHODS We searched PubMed, Scopus, Embase, the Cochrane Library, and Web of Science through April 19, 2018, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcomes of interest included the volume of blood loss, volume of transfusions, and operative time. A meta-analysis was performed with a random-effects model using Review Manager (RevMan) software (The Cochrane Collaboration, Copenhagen, Denmark). RESULTS We identified 32 eligible studies with 749 patients undergoing craniofacial surgery and 546 undergoing orthognathic surgery. Meta-analysis showed that antifibrinolytic use led to statistically significant decreases in blood loss and blood transfusions for craniofacial procedures in adult or pediatric patients and to significantly less blood loss during orthognathic surgical procedures. Operative time did not significantly differ for either type of surgery. CONCLUSIONS Antifibrinolytics can significantly reduce blood loss in craniofacial surgical procedures including pediatric craniosynostosis and adult rhinoplasties and in orthognathic surgical procedures, as well as transfusion requirements in pediatric craniofacial surgical procedures. However, the clinical significance of the medications is still questionable because of the relative paucity of information on adverse effects and the usual small volume loss during those operations.

Abstract
BACKGROUND Acute appendicitis is currently one of the most common surgical emergencies. Intra-abdominal abscesses (IAA) are a fearsome complication, which may occur. Irrigation during the appendectomy is one of the factors suggested to affect the rates of IAA. We sought to investigate the evidence regarding the use of irrigation versus suction alone and the development of IAA after laparoscopic appendectomy for complicated appendicitis. METHODS We searched PubMed, Scopus, Embase, Cochrane, and the Web of Science through November 10, 2017, according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. We extracted information of interest, including rates of postoperative (IAA), and performed meta-analysis using random-effects model using the RevMan software. RESULTS We identified five eligible studies with 2511 patients in total. Use of irrigation overall did not demonstrate significant increase in IAA (odds ratio [OR] = 2.39, 95% confidence interval [CI; 0.49, 11.74], P = 0.28). For the adult subpopulation, the use of irrigation was associated with nonsignificant lower odds of IAAs (OR = 0.42, 95% CI [0.15, 1.16]), whereas in pediatric with nonsignificant higher risk (OR = 2.98, 95% CI [0.25, 35.34]). Performance of irrigation led to the addition of, on average, 7 min to the duration of the operation (mean difference = 7.16, 95% CI [3.23, 11.09], P < 0.001). Irrigation did not affect postoperative length of stay (mean difference = -0.80, 95% CI [-2.30, 0.69], P = 0.29). CONCLUSIONS Performance of irrigation during laparoscopic appendectomy does not seem to prevent the development of IAA in neither adults nor pediatric patients.

Abstract
PURPOSE We conducted a systematic review to document ethical concerns regarding human upper extremity (UE) allotransplantation and how these concerns have changed over time. METHODS We performed a systematic review of 5 databases to find manuscripts addressing ethical concerns related to UE allotransplantation. Inclusion criteria were papers that were on the topic of UE allotransplantation, and related ethical concerns, written in English. We extracted and categorized ethical themes under the 4 principles of bioethics: Autonomy, Beneficence, Nonmaleficence, and Justice. We assessed theme frequency by publication year using Joinpoint regression, analyzing temporal trends, and estimating annual percent change. RESULTS We identified 474 citations; 49 articles were included in the final analysis. Publication years were 1998 to 2015 (mean, 3 publications/y; range, 0-7 publications/y). Nonmaleficence was most often addressed (46 of 49 papers; 94%) followed by autonomy (36 of 49; 74%), beneficence (35 of 49; 71%), and justice (31 of 49; 63%). Of the 14 most common themes, only "Need for More Research/Data" (nonmaleficence) demonstrated a significant increase from 1998 to 2002. CONCLUSIONS Upper extremity transplantation is an appealing reconstructive option for patients and physicians. Its life-enhancing (vs life-saving) nature and requirement for long-term immunosuppression have generated much ethical debate. Availability of human data has influenced ethical concerns over time. Our results indicate that discussion of ethical issues in the literature increased following publication of UE transplants and outcomes as well as after meetings of national societies and policy decisions by regulatory agencies. CLINICAL RELEVANCE Because UE transplantation is not a life-saving procedure, much ethical debate has accompanied its evolution. It is important for UE surgeons considering referring patients for evaluation to be aware of this discussion to fully educate patients and help them make informed treatment decisions.

Abstract
Studies show some return of breast sensation after breast reconstruction; however, recovery is variable and unpredictable. Efforts are being made to restore innervation by reattaching nerves (neurotization). We sought to systematically review the literature addressing breast sensation after reconstruction. The following databases were searched: EMBASE, Cochrane, and PubMed. Additionally, the PLASTIC AND RECONSTRUCTIVE SURGERY journal was hand searched from 1960 to 2009. Inclusion criteria included breast reconstruction for cancer, return of sensation with objective results, and patients aged 18 to 90 years. Studies with purely cosmetic procedures, case reports, studies with less than 10 patients, and studies involving male patients were excluded. The initial search yielded 109 studies, which was refined to 20 studies with a total pool of 638 patients. Innervated flaps have a greater magnitude of recovery, which occurs at an earlier stage compared with the noninnervated flaps. Overall, sensation to deep inferior epigastric artery perforator flaps may recover better sensation than transverse rectus abdominis myocutaneous flaps, followed by latissimus dorsi flaps, and finally implants. Women's needs and expectations for sensation have led plastic surgeons to investigate ways to facilitate its return. Studies, however, depict conflicting data. Larger series are needed to define the role of neurotization as a modality for improving sensory restoration.

Abstract
CD23, the low-affinity IgE receptor, is up-regulated on interleukin (IL)-4-stimulated B cells and monocytes, with a concomitant increase in the release of soluble fragments of CD23 (sCD23) into the medium by proteolytic processing of the surface-bound intact CD23. The effect of inhibition of the processing of CD23 on IgE production in human and mouse cells and in a mouse model in vivo was evaluated. CD23 processing to sCD23 from RPMI 8866 (a human Epstein-Barr virus-transformed B cell line) cell membranes was inhibited by a broad-spectrum matrix-metalloprotease inhibitor, batimastat, with an IC50 of 0.15 microM. Batimastat also inhibited CD23 processing in whole RPMI 8866 cells as well as in IL-4-stimulated purified human monocytes with similar IC50. Batimastat inhibited IgE production from IL-4/anti-CD40-stimulated human tonsil B cells as well as mouse splenic B cells in a manner consistent with inhibition of CD23 processing. Release of soluble fragments of CD23 in the cell supernatants of tonsil B cells was inhibited over the concentration range of 1-10 microM batimastat and intact cell surface CD23 was increased on mouse splenic B cells in the presence of these concentrations of batimastat. IgE production of IL-4-stimulated human peripheral blood mononuclear cells was also blocked by 1-10 microM batimastat, again with comparable inhibition of sCD23 release over the same concentration range. Finally, in a mouse model of IgE production, batimastat inhibited IgE production in response to ovalbumin challenge as determined by serum IgE levels. Taken together, the data support a role of CD23 in IgE production and point to CD23 processing to sCD23 as a therapeutically relevant control point in the regulation of IgE synthesis.
