    This consecutive nonrandomized comparative interventional study was designed to examine the association between pars plana vitrectomy (PPV) with or without internal limiting membrane (ILM) peeling in the treatment of idiopathic macular holes (IMH). The ILM is the innermost layer of the retina. The macula is located within the retina, and is responsible for central vision. Although IMH manifests in a relatively small region within the retina, patients notice significant drops in visual acuity up to the 20/400 - 20/800 level (legally blind in the affected eye). In the literature, the anatomic success rate of macular hole surgery has been reported between 48% - 94%. To best treat idiopathic macular holes, it is imperative that physicians have access to the most up-to-date information regarding the treatment outcomes. This study included 55 eyes of 52 patients who received surgery at the Beth Israel Deaconess Medical Center for idiopathic macular holes between December 1999 and January 2015. Patients were non-randomly assigned to PPV with or without ILM peeling. Early patients did not receive ILM peeling, while more recent patients did. The primary endpoint measured was macular hole (MH) status as established by ocular coherence tomography (OCT) within 6 to 12 months of the vii procedure. 36 out of 39 (92.3%) eyes in the ILM peeling group had closed MH. In the comparison group without ILM peeling, 11 out of 16 (68.8%) eyes had closed MH. In comparison to the conventional PPV without ILM peeling, these findings suggest that PPV with ILM peeling is associated with a significantly higher anatomic success rate (OR, 5.45; [95% CI, 1.12 to 26.55]; P = 0.023).2018-06-16T00:00:00

    Background: This study investigated the outcomes of coronavirus disease (COVID-19)-positive patients undergoing hip fracture surgery using a national database. Methods: This is a retrospective cohort study comparing hip fracture surgery outcomes between COVID-19 positive and negative matched cohorts from 46 sites in the United States. Patients aged 65 and older with hip fracture surgery between March 15 and December 31, 2020, were included. The main outcomes were 30-day all-cause mortality and all-cause mortality. Results: In this national study that included 3303 adults with hip fracture surgery, the 30-day mortality was 14.6% with COVID-19-positive versus 3.8% in COVID-19-negative, a notable difference. The all-cause mortality for hip fracture surgery was 27.0% in the COVID-19-positive group during the study period. Dicussion: We found higher incidence of all-cause mortality in patients with versus without diagnosis of COVID-19 after undergoing hip fracture surgery. The mortality in hip fracture surgery in this national analysis was lower than other local and regional reports. The medical community can use this information to guide the management of hip fracture patients with a diagnosis of COVID-19

    ience, this issue p. eaap8757 Structured Abstract INTRODUCTION Brain disorders may exhibit shared symptoms and substantial epidemiological comorbidity, inciting debate about their etiologic overlap. However, detailed study of phenotypes with different ages of onset, severity, and presentation poses a considerable challenge. Recently developed heritability methods allow us to accurately measure correlation of genome-wide common variant risk between two phenotypes from pools of different individuals and assess how connected they, or at least their genetic risks, are on the genomic level. We used genome-wide association data for 265,218 patients and 784,643 control participants, as well as 17 phenotypes from a total of 1,191,588 individuals, to quantify the degree of overlap for genetic risk factors of 25 common brain disorders. RATIONALE Over the past century, the classification of brain disorders has evolved to reflect the medical and scientific communities' assessments of the presumed root causes of clinical phenomena such as behavioral change, loss of motor function, or alterations of consciousness. Directly observable phenomena (such as the presence of emboli, protein tangles, or unusual electrical activity patterns) generally define and separate neurological disorders from psychiatric disorders. Understanding the genetic underpinnings and categorical distinctions for brain disorders and related phenotypes may inform the search for their biological mechanisms. RESULTS Common variant risk for psychiatric disorders was shown to correlate significantly, especially among attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder (MDD), and schizophrenia. By contrast, neurological disorders appear more distinct from one another and from the psychiatric disorders, except for migraine, which was significantly correlated to ADHD, MDD, and Tourette syndrome. We demonstrate that, in the general population, the personality trait neuroticism is significantly correlated with almost every psychiatric disorder and migraine. We also identify significant genetic sharing between disorders and early life cognitive measures (e.g., years of education and college attainment) in the general population, demonstrating positive correlation with several psychiatric disorders (e.g., anorexia nervosa and bipolar disorder) and negative correlation with several neurological phenotypes (e.g., Alzheimer's disease and ischemic stroke), even though the latter are considered to result from specific processes that occur later in life. Extensive simulations were also performed to inform how statistical power, diagnostic misclassification, and phenotypic heterogeneity influence genetic correlations. CONCLUSION The high degree of genetic correlation among many of the psychiatric disorders adds further evidence that their current clinical boundaries do not reflect distinct underlying pathogenic processes, at least on the genetic level. This suggests a deeply interconnected nature for psychiatric disorders, in contrast to neurological disorders, and underscores the need to refine psychiatric diagnostics. Genetically informed analyses may provide important "scaffolding" to support such restructuring of psychiatric nosology, which likely requires incorporating many levels of information. By contrast, we find limited evidence for widespread common genetic risk sharing among neurological disorders or across neurological and psychiatric disorders. We show that both psychiatric and neurological disorders have robust correlations with cognitive and personality measures. Further study is needed to evaluate whether overlapping genetic contributions to psychiatric pathology may influence treatment choices. Ultimately, such developments may pave the way toward reduced heterogeneity and improved diagnosis and treatment of psychiatric disorders

    Tarsometatarsal Joint Preparation Using a Modified Dorsal Approach vs. the Standard Approach: A Cadaver Study

    The standard surgical approach for the fusion of the tarsometatarsal (TMT) joint involves a two-incision approach. Philpott et al. proposed a modified, single-incision dorsal approach that yields a similar exposure. This study compares the joint preparation between the standard and modified dorsal approach. Ten fresh frozen cadaver specimens were randomly assigned to receive either a standard or modified dorsal operative approach to the TMT joint. The joint surface was prepared, and the joint was disarticulated. Image analysis, using ImageJ, was performed by two blinded reviewers to assess the joint surface preparation and this was compared by surgical approach. There was no significant difference in the amount of joint prepared when comparing the standard versus modified dorsal approach for TMT joints one through three (p = 0.548, p = 0.310, p = 0.548). First, TMT was 67.6% prepared by the standard approach vs 71.7% by the modified dorsal approach, second TMT was 67.9% vs. 65.7%, and third TMT was 65.9% vs. 59.6%. With our findings, we demonstrate that a modified dorsal approach with a single incision did not limit the ability to prepare the joint space. This study adds credibility backed by data to those set forth by Philipott et al

    Latinos in the United States experience numerous alcohol-related health disparities. There is accumulating evidence that pre-immigration factors are associated with post-immigration alcohol use, but the explanation for health disparities remains unclear. The present study is a secondary analysis of data from the Recent Latino Immigrant Study (RLIS), the first community-based cohort study to examine the pre- to post-immigration alcohol use trajectories of young adult Latino immigrants during their initial years in the United States. Exploratory analysis and hierarchical multiple logistic regression were performed to assess associations between various pre- and post-immigration factors and alcohol misuse among young adult Latino immigrants early in the immigration process. Using an ecodevelopmental approach, we examined potential social and environmental determinants across multiple levels of influence associated with post-immigration alcohol misuse in this population. The study sample consisted of 474 young adult Latino immigrants between the ages of 18–34. The sample was comprised of the following national/regional origins: Cuban (43%), South American (28.7%), and Central American (28.3%). Approximately half of the sample (49.6%) reported a family history of substance use problems (FHSUP+). Participants who reported FHSUP+ and who engaged in alcohol misuse prior to immigrating to the US were more likely to engage in post-immigration alcohol misuse. Results revealed various social and environmental factors associated with pre-immigration alcohol misuse in this population. Study findings can inform culturally tailored prevention interventions aimed at mitigating problem drinking behaviors among young adult recent Latino immigrants
