SS-OCTA performed before PRP and 1 week, 1 month, and 3 months after PRP confirmed that the precursor IRMA lesions were intraretinal tortuous vascular lesions at baseline and that they developed into preretinal NV with contiguous intraretinal components. NV was found to develop and adhere to the posterior hyaloid even in areas of pre-existing hyaloidal detachment. this website Conclusions and relevance Diabetic retinal NV can develop from IRMA. Early identification of IRMAs may be an accurate means of predicting progression to PDR, and frequent monitoring of IRMAs with SS-OCTA may facilitate early diagnosis of PDR.Purpose Infectious endophthalmitis is a devastating, yet rare complication following intraocular surgery, trauma, and systemic illness. Given its rare incidence, few patients would be expected to have more than one episode of infectious endophthalmitis in their lifetime. We reviewed our patients who were diagnosed with, and treated for, at least two separate episodes of endophthalmitis. Design A retrospective, consecutive case series was conducted of patients managed at Associated Retinal Consultants P.C. (Royal Oak, Michigan) from January 2013 thru December 2019. Subjects Patients were identified with the diagnosis of endophthalmitis by ICD-9/10 codes. Methods Those diagnosed and then treated with either a vitreous tap/intravitreal injection of antibiotics or pars plana vitrectomy at least two times were included. Those treated multiple times for the same episode of endophthalmitis were excluded. Main outcome measures Etiology and risk factors for recurrent endophthalmitis. Results Charts of 535 patients werciated with a worse final visual outcome. The cumulative number of intravitreal injections may be an independent risk factor for recurrent post-injection endophthalmitis.A semi-automated protocol has been developed for rotational data collection of electron diffraction patterns by combined use of SerialEM and ParallEM, where SerialEM is used for positioning of sample crystals and ParallEM for rotational data collection. ParallEM calls standard camera control software through an AutoIt script, which adapts to software operational changes and to new GUI programs guiding other cameras. Development included periodic flashing and pausing of data collection during overnight or day-long recording with a cold field-emission beam. The protocol proved to be efficient and accurate in data collection of large-scale rotational series from two JEOL electron microscopes, a general-purpose JEM-2100 and a high-end CRYO ARM 300. Efficiency resulted from simpler steps and task specialization. It is possible to collect 12-20 rotational series from ~-68° to ~68° at a rotation speed of 1°/s in one hour without human supervision.Background Coronavirus disease 2019 (COVID-19) is a respiratory syndrome with high rates of mortality, and there is a need for easily obtainable markers to provide prognostic information. We sought to determine whether the electrocardiogram (ECG) on hospital presentation provides prognostic information, specifically related to death. Methods and results We performed a retrospective cohort study in patients with COVID-19 who had an ECG at or near hospital admission. Clinical characteristics and ECG variables were manually abstracted from the electronic health record and first ECG. Our primary outcome was death. There were 756 patients who presented to a large New York City teaching hospital with COVID-19 who underwent an ECG. The mean age was 63.3 ± 16 years, 37% were women, 61% of patients were nonwhite, and 57% had hypertension; 90 (11.9%) died. In a multivariable logistic regression that included age, ECG, and clinical characteristics, the presence of one or more atrial premature contractions (odds ratio [OR] 2.57, 95% confidence interval [CI] 1.23-5.36, P = .01), a right bundle branch block or intraventricular block (OR 2.61, 95% CI 1.32-5.18, P = .002), ischemic T-wave inversion (OR 3.49, 95% CI 1.56-7.80, P = .002), and nonspecific repolarization (OR 2.31, 95% CI 1.27-4.21, P = .006) increased the odds of death. ST elevation was rare (n = 5 [0.7%]). Conclusions We found that patients with ECG findings of both left-sided heart disease (atrial premature contractions, intraventricular block, repolarization abnormalities) and right-sided disease (right bundle branch block) have higher odds of death. ST elevation at presentation was rare.Background Acute bilateral internal carotid artery (ICA) occlusion has rarely been reported to exhibit an improvement in prognosis. Herein, we report a case of acute bilateral ICA occlusion presenting with bilateral symmetrical cortical and basal-ganglia infarctions that exhibited dramatic improvement after a mechanical thrombectomy. Case description The patient was a 72-year-old man with a history of hypertension who presented with a coma and quadriplegia during sleep and experienced moderate vomiting and diarrhea the day before admission to our hospital. Neurological examination revealed that the patient was in a coma (NIHSS 35). A brain computed tomography (CT) scan showed a hypodense lesion in the bilateral frontal cortex. An emergency cerebral angiography demonstrated complete occlusion of the bilateral ICA. Subsequently, a mechanical thrombectomy of the bilateral ICA was successfully performed. At a three-month follow-up, the patient had residual slight aphasia and quadriparesis (NIHSS 16). Conclusions Bilateral ICA occlusion should be considered if a patient presents with a coma, quadriplegia, and symmetrical cortical infarctions. In such a case, a bilateral mechanical thrombectomy may represent a potential treatment for improving the prognosis of the affected patient.Minimally invasive spine surgery (MISS) has continued to evolve over the past few decades, with significant advancements in technology and technical skills. From endonasal cervical approaches to extreme lateral lumbar interbody fusions, MISS has showcased its utility across all practice areas of the spine, with unique points of access to avoid pertinent neurovascular structures. The field of adult spine deformity has also recognized the importance of minimally invasive techniques in its ability to limit complications, while providing adequate sagittal alignment correction and improvements in patients' functional status. Although MISS has continued to make significant progress clinically, consideration must also be given to its economic impact and the learning curve surgeons experience in adding these procedures to their armamentarium. This review aims to examine current innovations in the field of MISS, as well as the economic impact and future directions of the field.
