RESUMEN
BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disease that disproportionally affects women, as well as Black and biracial individuals. While adalimumab remains the only therapy approved by the Food and Drug Administration for HS, many HS clinical trials for novel and re-tasked therapies are ongoing or upcoming. To optimize treatment equity, reflect the patient population, and facilitate trial participation, it is important to elucidate aspects of clinical trial protocols that may systematically exclude specific patient groups or impose hardships. OBJECTIVE: The study aimed to systematically review inclusion and exclusion criteria as well as participant demographics in HS clinical trials. METHODS: A literature search of PubMed, Embase, Cochrane Central, and Web of Science databases was conducted. Peer-reviewed publications of randomized controlled trials that were written in English and had at least 10 participants were included. Title and abstract screening and data extraction were completed by two independent reviewers, with disagreements resolved by a third. RESULTS: Twenty-three studies totaling 1,496 adult participants met the inclusion criteria. Race and ethnicity were not reported in 473/1,496 (31.6%) and 1,420/1,496 (94.9%) trial participants, respectively. Trial participants were predominantly white (811/1,023, 79.3%) and female (1,057/1,457, 72.5%). The median of each study's average age was 35.7 years (IQR 33.5-38.0), and 17/23 (73.9%) trials excluded pediatric patients. Nearly all participants had Hurley Stage II (499/958, 52.0%) or Hurley Stage III (385/958, 40.2%) disease. Many trials excluded patients who were pregnant (19/23, 82.6%) and breastfeeding (13/23, 56.5%), or who had HS that was "too severe" (8/23, 34.8%) or "too mild" (16/23, 70.0%). Frequently, trial protocols required prolonged washout periods from HS therapies, relatively long duration in the study's placebo arm, and prohibited concurrent analgesic use. CONCLUSIONS: This systematic review of 23 HS clinical trials totaling 1,496 participants identified substantial hardships imposed by trial participation, high rates of missing race and ethnicity data, and low representation of key patient groups, including those who identify as Black. Future trials with pragmatic study designs, broader inclusion criteria, and study sites in diverse communities may alleviate burdens of trial participation and improve enrollment of diverse patient groups.

The purpose of this review was to summarize the current literature pertaining to ultrasound-guided percutaneous A1 pulley release procedures. We searched PubMed, Cochrane Library, Embase, and Web of Science for clinical studies examining ultrasound-guided percutaneous A1 pulley release. A total of 17 studies involving 749 procedures were included in this review. The overall success rate was 97%. There were 23 minor complications (4 cases of hematomas, 15 cases of persistent pain, and 4 cases of transient numbness) and no major complications reported. Ultrasound-guided A1 pulley release is an effective and safe procedure for the treatment of trigger fingers and thumb.
RESUMEN
Lumpy skin disease virus (LSDV) is a vector-transmitted poxvirus that causes disease in cattle. Vector species involved in LSDV transmission and their ability to acquire and transmit the virus are poorly characterized. Using a highly representative bovine experimental model of lumpy skin disease, we fed four model vector species (Aedes aegypti, Culex quinquefasciatus, Stomoxys calcitrans, and Culicoides nubeculosus) on LSDV-inoculated cattle in order to examine their acquisition and retention of LSDV. Subclinical disease was a more common outcome than clinical disease in the inoculated cattle. Importantly, the probability of vectors acquiring LSDV from a subclinical animal (0.006) was very low compared with that from a clinical animal (0.23), meaning an insect feeding on a subclinical animal was 97% less likely to acquire LSDV than one feeding on a clinical animal. All four potential vector species studied acquired LSDV from the host at a similar rate, but Aedes aegypti and Stomoxys calcitrans retained the virus for a longer time, up to 8 days. There was no evidence of virus replication in the vector, consistent with mechanical rather than biological transmission. The parameters obtained in this study were combined with data from studies of LSDV transmission and vector life history parameters to determine the basic reproduction number of LSDV in cattle mediated by each of the model species. This reproduction number was highest for Stomoxys calcitrans (19.1), followed by C. nubeculosus (7.1) and Ae. aegypti (2.4), indicating that these three species are potentially efficient transmitters of LSDV; this information can be used to inform LSD control programs.IMPORTANCE Lumpy skin disease virus (LSDV) causes a severe systemic disease characterized by cutaneous nodules in cattle. LSDV is a rapidly emerging pathogen, having spread since 2012 into Europe and Russia and across Asia. The vector-borne nature of LSDV transmission is believed to have promoted this rapid geographic spread of the virus; however, a lack of quantitative evidence about LSDV transmission has hampered effective control of the disease during the current epidemic. Our research shows subclinical cattle play little part in virus transmission relative to clinical cattle and reveals a low probability of virus acquisition by insects at the preclinical stage. We have also calculated the reproductive number of different insect species, therefore identifying efficient transmitters of LSDV. This information is of utmost importance, as it will help to define epidemiological control measures during LSDV epidemics and of particular consequence in resource-poor regions where LSD vaccination may be less than adequate.

Introduction: Local tissue destruction following envenomation from North American snakes, particularly those within the Crotalinae subfamily, has the potential to progress to compartment syndrome. The pathophysiology of venom-induced compartment syndrome (VICS) is a debated topic and is distinct from trauma/reperfusion-induced compartment syndrome. Heterogeneity exists in the treatment practices of VICS, particularly regarding the decision to progress to fasciotomy. Associations with functional outcomes and evolution in clinical practice since the introduction of Crotalidae polyvalent immune Fab (FabAV) have not been well defined. Our goal was to identify the potential gaps in the literature regarding this phenomenon, as well as illuminate salient themes in the clinical characteristics and treatment practices of VICS. Methods: We conducted this systematic scoping-style review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Records were included if they contained data surrounding the envenomation and hospital course of one or more patients who were envenomated by a snake species native to North America and were diagnosed with compartment syndrome from 1980-2020. Results: We included 19 papers: 10 single- or two-patient case reports encompassing 12 patients, and nine chart reviews providing summary statistics of the included patients. In case reports, the median compartment pressure when reported was 60 millimeters of mercury (interquartile range 55-68), 66% underwent fasciotomy, and functional outcomes varied. Use of antivenom appeared to be more liberal with FabAV than the earlier antivenin Crotalidae polyvalent. Rapid progression of swelling was the most commonly reported symptom. Among the included retrospective chart reviews, important data such as compartment pressures, consistent laboratory values, and snake species was inconsistently reported. Conclusions: Venom-induced compartment syndrome is relatively rare. Existing papers generally describe good outcomes even in the absence of surgical management. Significant gaps in the literature regarding antivenom dosing practices, serial compartment pressure measurements, and functional outcomes highlight the need for prospective studies and consistent standardized reporting.

Introduction: The endogenous cannabinoid (endocannabinoid) system is an emerging target for the treatment of chronic inflammatory disease with the potential to advance treatment for many respiratory illnesses. The varied effects of endocannabinoids across tissue types makes it imperative that we explore their physiologic impact within unique tissue targets. The aim of this scoping review is to explore the impact of endocannabinoid activity on eicosanoid production as a measure of human airway inflammation. Methods: A scoping literature review was conducted according to PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Search strategies using MeSH terms related to cannabinoids, eicosanoids, cyclooxygenase (COX), and the respiratory system were used to query Medline, Embase, Cochrane, CINAHL, Web of Science, and Biosis Previews in December 2021. Only studies that investigated the relationship between endocannabinoids and the eicosanoid system in mammalian respiratory tissue after 1992 were included. Results: Sixteen studies were incorporated in the final qualitative review. Endocannabinoid activation increases COX-2 expression, potentially through ceramide-dependent or p38 and p42/44 Mitogen-Activated Protein Kinase pathways and is associated with a concentration-dependent increase in prostaglandin (PG)E2. Inhibitors of endocannabinoid hydrolysis found either an increase or no change in levels of PGE2 and PGD2 and decreased levels of leukotriene (LT)B4, PGI2, and thromboxane A2 (TXA2). Endocannabinoids increase bronchial epithelial cell permeability and have vasorelaxant effects in human pulmonary arteries and cause contraction of bronchi and decreased gas trapping in guinea pigs. Inhibitors of endocannabinoid hydrolysis were found to have anti-inflammatory effects on pulmonary tissue and are primarily mediated by COX-2 and activation of eicosanoid receptors. Direct agonism of endocannabinoid receptors appears to play a minor role. Conclusion: The endocannabinoid system has diverse effects on the mammalian airway. While endocannabinoid-derived PGs can have anti-inflammatory effects, endocannabinoids also produce proinflammatory conditions, such as increased epithelial permeability and bronchial contraction. These conflicting findings suggest that endocannabinoids produce a variety of effects depending on their local metabolism and receptor agonism. Elucidation of the complex interplay between the endocannabinoid and eicosanoid pathways is key to leveraging the endocannabinoid system as a potential therapeutic target for human airway disease.

In 2009, the Woodruff Health Sciences Center Library started a library instruction dialogue with the medical students and faculty from the Emory School of Medicine. These discussions exposed a gap among faculty, students, and librarians in their perceptions of information processing. Follow-ups with the Associate Deans for Student Affairs and Medical Education led to the decision to administer an online assessment of the incoming student body and a complete redesign of the library orientation program. The aim of using self-assessment methodology in the framework of an orientation program was to set the students' foundation for self-discovery and introduce them to self-learning.

OBJECTIVE/HYPOTHESIS: The goal of this scoping review is to evaluate and synthesize the published research regarding bullying and children who are deaf or hard-of-hearing (DHH). STUDY DESIGN: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping review (PRISMA-ScR) statement was used as the guideline for conducting this review. METHODS: This review included studies assessing pediatric (0-21 years) DHH children. Seventy records underwent the initial title-abstract screening, 33 underwent full-text review, and 23 studies met inclusion criteria. During the data extraction process, an additional six were excluded, resulting in a total of 17 evaluated studies. RESULTS: Of the 17 studies assessed, nine compared peer victimization of DHH children and their hearing peers. Of those, seven studies reported that hearing loss (HL) is significantly associated with increased victimization. Two studies found that HL is significantly associated with decreased bullying perpetration. Notably, bullying in DHH children was not associated with a visible sign of disability, such as a hearing assistive device. Rather, variables such as educational setting, parental, and peer support are more likely to mediate bullying in this population. CONCLUSIONS: DHH children have a higher risk of peer victimization and may bully others less often than their hearing peers. Studies described the health consequences of bullying in children who are DHH, including sleep issues and anxiety. These consequences may have implications for the patients' overall HL management. Additional research regarding bullying interventions and prevention in this population should be conducted. LEVEL OF EVIDENCE: NA Laryngoscope, 131:1884-1892, 2021.

BACKGROUND: In the United States (US), barriers in access to later steps in the kidney transplantation process (i.e. waitlisting) have been well documented. Barriers in access to earlier steps (i.e. referral and evaluation) are less well described due to the lack of national surveillance data. In this review, we summarize the available literature on non-medical barriers in access to kidney transplant referral and evaluation. METHODS: Following PRISMA guidelines, we conducted a scoping review of the literature through June 3, 2021. We included all studies (quantitative and qualitative) reporting on barriers to kidney transplant referral and evaluation in the US published from 1990 onwards in English and among adult end-stage kidney disease (ESKD) patients (PROSPERO registration number: CRD42014015027). We narratively synthesized results across studies. RESULTS: We retrieved information from 33 studies published from 1990 to 2021 (reporting data between 1990 and 2018). Most studies (n = 28, 85%) described barriers among patient populations, three (9%) among provider populations, and two (6%) included both patients and providers. Key barriers were identified across multiple levels and included patient- (e.g. demographic, socioeconomic, sociocultural, and knowledge), provider- (e.g. miscommunication, staff availability, provider perceptions and attitudes), and system- (e.g. geography, distance to care, healthcare logistics) level factors. CONCLUSIONS: A multi-pronged approach (e.g. targeted and systemwide interventions, and policy change) implemented at multiple levels of the healthcare system will be necessary to reduce identified barriers in access to early kidney transplant steps. Collection of national surveillance data on these early kidney transplant steps is also needed to enhance our understanding of barriers to referral and evaluation.

Background. Outbreaks of mosquito-borne arboviral diseases including dengue virus (DENV), Zika virus (ZIKV), yellow fever virus (YFV) and chikungunya virus (CHIKV) have recently occurred in the Caribbean. The geographical range of the principal vectors responsible for transmission, Aedes (Ae.) aegypti and Ae. albopictus are increasing and greater mosquito surveillance is needed in the Caribbean given international tourism is so prominent. The island of Saint Lucia has seen outbreaks of DENV and CHIKV in the past five years but vector surveillance has been limited with the last studies dating back to the late 1970s. Natural disasters have changed the landscape of Saint Lucia and the island has gone through significant urbanisation. Methods. In this study, we conducted an entomological survey of Ae. aegypti and Ae. albopictus distribution across the island and analysed environmental parameters associated with the presence of these species in addition to screening for medically important arboviruses and other flaviviruses. Results. Although we collected Ae. aegypti across a range of sites across the island, no Ae. albopictus were collected despite traps being placed in diverse ecological settings. The number of Ae. aegypti collected was significantly associated with higher elevation, and semi-urban settings yielded female mosquito counts per trap-day that were five-fold lower than urban settings. Screening for arboviruses revealed a high prevalence of cell-fusing agent virus (CFAV). Conclusions. Outbreaks of arboviruses transmitted by Ae. aegypti and Ae. albopictus have a history of occurring in small tropical islands and Saint Lucia is particularly vulnerable given the limited resources available to undertake vector control and manage outbreaks. Surveillance strategies can identify risk areas for predicting future outbreaks. Further research is needed to determine the diversity of current mosquito species, investigate insect-specific viruses, as well as pathogenic arboviruses, and this should also be extended to the neighbouring smaller Caribbean islands.
RESUMEN
Red blood cells (RBC) transfusion is critical in managing acute and chronic complications in sickle cell disease (SCD); however, it is complicated by RBC alloimmunization, iron overload, transfusion reactions and infection. Several reports documented an increased incidence of alloantibodies in transfused individuals with SCD, especially for Rh and Kell antigens. As a result, the National Institutes of Health Expert Panel and British Society for Haematology guidelines recommend primary matching for C/c, E/e and K antigens in addition to ABO/RhD for RBC transfusions. However, the evidence supporting these recommendations was cited as limited and understanding of alloimmunization in SCD is evolving. To examine the limitations of the evidence, we undertook a systematic review of evidence behind recommendations for limited and extended serologic and genotypic RBC antigen matching to reduce alloimmunization, autoimmunization and transfusion reactions. Searches of PubMed, Embase, Cochrane, and Web of Science databases using MeSH index and free text terms between 1976 through October 2015 and papers and captured through July 2016 through review references in papers, word of mouth, and ongoing Google Scholar and Medline Alerts identified 303 unique articles. Nineteen articles met inclusion criteria and were classified by the Oxford Centre Evidence Based levels of evidence. Strengthening the Reporting of Observational Studies in Epidemiology checklists were completed for 18 of the 19 studies. There were no prospective randomized controlled trials. Sixteen of the articles were cohort studies, two were cross-sectional studies, and one decision tree model examining costs. Low-quality evidence from observational cohort studies supports that alloimmunization prevalence can be decreased by extending serological RBC antigen matching. Transfusion reactions are generally poorly and inconsistently reported. There was no evidence reporting the effect prophylactic genotypic matching has on alloimmunization, autoimmunization or transfusion reactions. There were no studies comparing prophylactic genotypic matching to serologic matching. High-quality evidence was lacking to support clinical decision making regarding best transfusion practices. Multicenter prospective randomized clinical trials are needed to determine best strategies for reducing the rate of alloimmunization using serologic and genotypic matching.
