  • Community and Close Contact Exposures Associated with COVID-19 Among Symptomatic Adults >= 18Years in 11 Outpatient Health Care Facilities - United States, July 2020 MMWR-MORBIDITY AND MORTALITY WEEKLY REPORT Fisher, K. A., Tenforde, M. W., Feldstein, L. R., Lindsell, C. J., Shapiro, N., Files, D., Gibbs, K. W., Erickson, H. L., Prekker, M. E., Steingrub, J. S., Exline, M. C., Henning, D. J., Wilson, J.

H., IVY Network Investigators, CDC COVID-19 Response Team 2020; 69 (36): 1258?64

    Abstract

    Community and close contact exposures continue to drive the coronavirus disease 2019 (COVID-19) pandemic. CDC and other public health authorities recommend community mitigation strategies to reduce transmission of SARS-CoV-2, the virus that causes COVID-19 (1,2). Characterization of community exposures can be difficult to assess when widespread transmission is occurring, especially from asymptomatic persons within inherently interconnected communities. Potential exposures, such as close contact with a person with confirmed COVID-19, have primarily been assessed among COVID-19 cases, without a non-COVID-19 comparison group (3,4). To assess community and close contact exposures associated with COVID-19, exposures reported by case-patients (154) were compared with exposures reported by control-participants (160). Case-patients were symptomatic adults (persons aged ?18 years) with SARS-CoV-2 infection confirmed by reverse transcription-polymerase chain reaction (RT-PCR) testing. Control-participants were symptomatic outpatient adults from the same health care facilities who had negative SARS-CoV-2 test results. Close contact with a person with known COVID-19 was more commonly reported among case-patients (42%) than among control-participants (14%). Case-patients were more likely to have reported dining at a restaurant (any area designated by the restaurant, including indoor, patio, and outdoor seating) in the 2 weeks preceding illness onset than were control-participants (adjusted odds ratio [aOR] = 2.4; 95% confidence interval [CI] = 1.5-3.8). Restricting the analysis to participants without known close contact with a person with confirmed COVID-19, case-patients were more likely to report dining at a restaurant (aOR = 2.8, 95% CI = 1.9-4.3) or going to a bar/coffee shop (aOR = 3.9, 95% CI = 1.5-10.1) than were control-participants. Exposures and activities where mask use and social distancing are difficult to maintain, including going to places that offer on-site eating or drinking, might be important risk factors for acquiring COVID-19. As communities reopen, efforts to reduce possible exposures at locations that offer on-site eating and drinking options should be considered to protect customers, employees, and communities.

  • Cytokine profile in plasma of severe COVID-19 does not differ from ARDS and sepsis. JCI insight Wilson, J. G., Simpson, L. J., Ferreira, A., Rustagi, A., Roque, J.

    Abstract

    BACKGROUND: Elevated levels of inflammatory cytokines have been associated with poor outcomes among COVID-19 patients. It is unknown, however, how these levels compare to those observed in critically ill patients with ARDS or sepsis due to other causes.METHODS: We used a luminex assay to determine expression of 76 cytokines from plasma of hospitalized COVID-19 patients and banked plasma samples from ARDS and sepsis patients. Our analysis focused on detecting statistical differences in levels of 6 cytokines associated with cytokine storm (IL-1b, IL-1RA, IL-6, IL-8, IL-18, and TNFalpha) between patients with moderate COVID-19, severe COVID-19, and ARDS or sepsis.RESULTS: 15 hospitalized COVID-19 patients, 9 of whom were critically ill, were compared to critically ill patients with ARDS (n = 12) or sepsis (n = 16). There were no statistically significant differences in baseline levels of IL-1b, IL-1RA, IL-6, IL-8, IL-18, and TNFalpha between patients with COVID-19 and critically ill controls with ARDS or sepsis.CONCLUSIONS: Levels of inflammatory cytokines were not higher in severe COVID-19 patients than in moderate COVID-19 or critically ill patients with ARDS or sepsis in this small cohort. Broad use of immunosuppressive therapies in ARDS has failed in numerous Phase 3 studies; use of these therapies in unselected patients with COVID-19 may be unwarranted.FUNDING: A.J.R.: Stanford ICU Biobank NHLBI K23 HL125663.

  • Characteristics of Adult Outpatients and Inpatients with COVID-19-11 Academic Medical Centers, United States, March-May 2020 MMWR-MORBIDITY AND MORTALITY WEEKLY REPORT Tenforde, M. W., Rose, E., Lindsell, C. J., Shapiro, N., Files, D., Gibbs, K. W., Prekker, M. E., Steingrub, J. S., Smithline, H. A., Gong, M. N., Aboodi, M. S., Exline, M. C., Henning, D. J., Wilson, J.

    Abstract

    Descriptions of coronavirus disease 2019 (COVID-19) in the United States have focused primarily on hospitalized patients. Reports documenting exposures to SARS-CoV-2, the virus that causes COVID-19, have generally been described within congregate settings, such as meat and poultry processing plants (1) and long-term care facilities (2). Understanding individual behaviors and demographic characteristics of patients with COVID-19 and risks for severe illness requiring hospitalization can inform efforts to reduce transmission. During April 15-May 24, 2020, telephone interviews were conducted with a random sample of adults aged ?18 years who had positive reverse transcription-polymerase chain reaction (RT-PCR) test results for SARS-CoV-2 in outpatient and inpatient settings at 11 U.S. academic medical centers in nine states. Respondents were contacted 14-21 days after SARS-CoV-2 testing and asked about their demographic characteristics, underlying chronic conditions, symptoms experienced on the date of testing, and potential exposures to SARS-CoV-2 during the 2 weeks before illness onset (or the date of testing among those who did not report symptoms at the time of testing). Among 350 interviewed patients (271 [77%] outpatients and 79 [23%] inpatients), inpatients were older, more likely to be Hispanic and to report dyspnea than outpatients. Fewer inpatients (39%, 20 of 51) reported a return to baseline level of health at 14-21 days than did outpatients (64%, 150 of 233) (p = 0.001). Overall, approximately one half (46%) of patients reported known close contact with someone with COVID-19 during the preceding 2 weeks. This was most commonly a family member (45%) or a work colleague (34%). Approximately two thirds (64%, 212 of 333) of participants were employed; only 35 of 209 (17%) were able to telework. These findings highlight the need for screening, case investigation, contact tracing, and isolation of infected persons to control transmission of SARS-CoV-2 infection during periods of community transmission. The need for enhanced measures to ensure workplace safety, including ensuring social distancing and more widespread use of cloth face coverings, are warranted (3).

  • Symptom Duration and Risk Factors for Delayed Return to Usual Health Among Outpatients with COVID-19 in a Multistate Health Care Systems Network - United States, March-June 2020. MMWR. Morbidity and mortality weekly report Tenforde, M. W., Kim, S. S., Lindsell, C. J., Billig Rose, E., Shapiro, N. I., Files, D. C., Gibbs, K. W., Erickson, H. L., Steingrub, J. S., Smithline, H. A., Gong, M. N., Aboodi, M. S., Exline, M. C., Henning, D. J., Wilson, J. G., Khan, A., Qadir, N., Brown, S. M., Peltan, I. D., Rice, T. W., Hager, D. N., Ginde, A. A., Stubblefield, W. B., Patel, M. M., Self, W. H., Feldstein, L. R. 2020; 69 (30): 993?98

    Abstract

    Prolonged symptom duration and disability are common in adults hospitalized with severe coronavirus disease 2019 (COVID-19). Characterizing return to baseline health among outpatients with milder COVID-19 illness is important for understanding the full spectrum of COVID-19-associated illness and tailoring public health messaging, interventions, and policy. During April 15-June 25, 2020, telephone interviews were conducted with a random sample of adults aged ?18 years who had a first positive reverse transcription-polymerase chain reaction (RT-PCR) test for SARS-CoV-2, the virus that causes COVID-19, at an outpatient visit at one of 14 U.S. academic health care systems in 13 states. Interviews were conducted 14-21 days after the test date. Respondents were asked about demographic characteristics, baseline chronic medical conditions, symptoms present at the time of testing, whether those symptoms had resolved by the interview date, and whether they had returned to their usual state of health at the time of interview. Among 292 respondents, 94% (274) reported experiencing one or more symptoms at the time of testing; 35% of these symptomatic respondents reported not having returned to their usual state of health by the date of the interview (median = 16 days from testing date), including 26% among those aged 18-34 years, 32% among those aged 35-49 years, and 47% among those aged ?50 years. Among respondents reporting cough, fatigue, or shortness of breath at the time of testing, 43%, 35%, and 29%, respectively, continued to experience these symptoms at the time of the interview. These findings indicate that COVID-19 can result in prolonged illness even among persons with milder outpatient illness, including young adults. Effective public health messaging targeting these groups is warranted. Preventative measures, including social distancing, frequent handwashing, and the consistent and correct use of face coverings in public, should be strongly encouraged to slow the spread of SARS-CoV-2.

  • Telework Before Illness Onset Among Symptomatic Adults Aged ?18 Years With and Without COVID-19 in 11 Outpatient Health Care Facilities - United States, July 2020. MMWR. Morbidity and mortality weekly report Fisher, K. A., Olson, S. M., Tenforde, M. W., Feldstein, L. R., Lindsell, C. J., Shapiro, N. I., Files, D. C., Gibbs, K. W., Erickson, H. L., Prekker, M.

G., Flannery, B., Patel, M. M., Self, W. H. 2020; 69 (44): 1648?53

    Abstract

    Since March 2020, large-scale efforts to reduce transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), have continued. Mitigation measures to reduce workplace exposures have included work site policies to support flexible work site options, including telework, whereby employees work remotely without commuting to a central place of work.* Opportunities to telework have varied across industries among U.S. jobs where telework options are feasible (1). However, little is known about the impact of telework on risk for SARS-CoV-2 infection. A case-control investigation was conducted to compare telework between eligible symptomatic persons who received positive SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test results (case-patients, 153) and symptomatic persons with negative test results (control-participants, 161). Eligible participants were identified in outpatient health care facilities during July 2020. Among employed participants who reported on their telework status during the 2 weeks preceding illness onset (248), the percentage who were able to telework on a full- or part-time basis was lower among case-patients (35%; 42 of 120) than among control-participants (53%; 68 of 128) (p<0.01). Case-patients were more likely than were control-participants to have reported going exclusively to an office or school setting (adjusted odds ratio [aOR] = 1.8; 95% confidence interval [CI] = 1.2-2.7) in the 2 weeks before illness onset. The association was also observed when further restricting to the 175 participants who reported working in a profession outside the critical infrastructure? (aOR = 2.1; 95% CI = 1.3-3.6). Providing the option to work from home or telework when possible, is an important consideration for reducing the risk for SARS-CoV-2 infection. In industries where telework options are not available, worker safety measures should continue to be scaled up to reduce possible worksite exposures.

  • Early High-Dose Vitamin D3 for Critically Ill, Vitamin D-Deficient Patients. The New England journal of medicine National Heart, L., Ginde, A. A., Brower, R. G., Caterino, J. M., Finck, L., Banner-Goodspeed, V. M., Grissom, C. K., Hayden, D., Hough, C. L., Hyzy, R. C., Khan, A., Levitt, J. E., Park, P. K., Ringwood, N., Rivers, E. P., Self, W. H., Shapiro, N. I., Thompson, B. T., Yealy, D. M., Talmor, D. 2019

    Abstract

    BACKGROUND: Vitamin D deficiency is a common, potentially reversible contributor to morbidity and mortality among critically ill patients. The potential benefits of vitamin D supplementation in acute critical illness require further study.METHODS: We conducted a randomized, double-blind, placebo-controlled, phase 3 trial of early vitamin D3 supplementation in critically ill, vitamin D-deficient patients who were at high risk for death. Randomization occurred within 12 hours after the decision to admit the patient to an intensive care unit. Eligible patients received a single enteral dose of 540,000 IU of vitamin D3 or matched placebo. The primary end point was 90-day all-cause, all-location mortality.RESULTS: A total of 1360 patients were found to be vitamin D-deficient during point-of-care screening and underwent randomization. Of these patients, 1078 had baseline vitamin D deficiency (25-hydroxyvitamin D level, <20 ng per milliliter [50 nmol per liter]) confirmed by subsequent testing and were included in the primary analysis population. The mean day 3 level of 25-hydroxyvitamin D was 46.9±23.2 ng per milliliter (117±58 nmol per liter) in the vitamin D group and 11.4±5.6 ng per milliliter (28±14 nmol per liter) in the placebo group (difference, 35.5 ng per milliliter; 95% confidence interval [CI], 31.5 to 39.6). The 90-day mortality was 23.5% in the vitamin D group (125 of 531 patients) and 20.6% in the placebo group (109 of 528 patients) (difference, 2.9 percentage points; 95% CI, -2.1 to 7.9; P=0.26). There were no clinically important differences between the groups with respect to secondary clinical, physiological, or safety end points. The severity of vitamin D deficiency at baseline did not affect the association between the treatment assignment and mortality.CONCLUSIONS: Early administration of high-dose enteral vitamin D3 did not provide an advantage over placebo with respect to 90-day mortality or other, nonfatal outcomes among critically ill, vitamin D-deficient patients.

  • End-of-Life Care, Palliative Care Consultation, and Palliative Care Referral in the Emergency Department: A Systematic Review. Journal of pain and symptom management Wilson, J. G., English, D. P., Owyang, C. G., Chimelski, E. A., Grudzen, C. R., Wong, H., Aslakson, R. A. 2019

    Abstract

    CONTEXT: There is growing interest in providing palliative care (PC) in the emergency department (ED), but relatively little is known about the efficacy of ED-based PC interventions. A 2016 systematic review on this topic found no evidence that ED-based PC interventions affect patient outcomes or healthcare utilization, but new research has emerged since the publication of that review.OBJECTIVE: This systematic review provides a concise summary of current literature addressing the impact of ED-based PC interventions on patient- or family-reported outcomes, healthcare utilization, and survival.METHODS: We searched Pubmed, Embase, Web of Science, Scopus and CINAHL from inception until September 1, 2018 and reviewed references. Eligible articles evaluated the effects of PC interventions in the ED on patient- or family-reported outcomes, healthcare utilization, or survival.RESULTS: We screened 3091 abstracts and 98 full text articles with 13 articles selected for final inclusion. Two articles reported the results of a single RCT, while the remaining 11 studies were descriptive or quasi-experimental cohort studies. Over half of the included articles were published after the previous systematic review on this topic. Populations studied included older adults, patients with advanced malignancy, and ED patients screening positive for unmet palliative care needs. Most interventions involved referral to hospice or PC, or PC provided directly in the ED. Compared to usual care, ED-PC interventions improved quality of life, though this improvement was not observed when comparing ED-PC to inpatient-PC. ED-PC interventions expedited PC consultation; most studies reported a concomitant reduction in hospital length-of-stay and increase in hospice utilization, but some data were conflicting. Short-term mortality rates were high across all studies, but ED-PC interventions did not decrease survival time compared to usual care.CONCLUSION: Existing data support that PC in the ED is feasible, may improve quality of life, and does not appear to affect survival.

  • Critical Care Ultrasound: A Review for Practicing Nephrologists ADVANCES IN CHRONIC KIDNEY DISEASE Wilson, J. G., Breyer, K. E. 2016; 23 (3): 141-145

    Abstract

    The use of point-of-care ultrasound in the intensive care unit, both for diagnostic and procedural purposes, has rapidly proliferated, and evidence supporting its use is growing. Conceptually, critical care ultrasound (CCUS) should be considered an extension of the physical examination and should not be considered a replacement for formal echocardiography or radiology-performed ultrasound. Several CCUS applications are of particular relevance to nephrologists, including focused renal ultrasound in patients at high risk for urinary tract obstruction, real-time ultrasound guidance and verification during the placement of central venous catheters, and ultrasound-augmented assessment of shock and volume status. Each of these applications has the capacity to improve outcomes in patients with acute kidney injury. Although robust evidence regarding long-term outcomes is lacking, existing data demonstrate that CCUS has the potential to improve diagnostic accuracy, expedite appropriate management, and increase safety for critically ill patients across a spectrum of pathologies.

  • Mesenchymal stem (stromal) cells for treatment of ARDS: a phase 1 clinical trial. The Lancet. Respiratory medicine Wilson, J. G., Liu, K. D., Zhuo, H., Caballero, L., McMillan, M., Fang, X., Cosgrove, K., Vojnik, R., Calfee, C. S., Lee, J., Rogers, A. J., Levitt, J., Wiener-Kronish, J., Bajwa, E. K., Leavitt, A., McKenna, D., Thompson, B. T., Matthay, M. A. 2015; 3 (1): 24-32

    Abstract

    No effective pharmacotherapy for acute respiratory distress syndrome (ARDS) exists, and mortality remains high. Preclinical studies support the efficacy of mesenchymal stem (stromal) cells (MSCs) in the treatment of lung injury. We aimed to test the safety of a single dose of allogeneic bone marrow-derived MSCs in patients with moderate-to-severe ARDS.The STem cells for ARDS Treatment (START) trial was a multicentre, open-label, dose-escalation, phase 1 clinical trial. Patients were enrolled in the intensive care units at University of California, San Francisco, CA, USA, Stanford University, Stanford, CA, USA, and Massachusetts General Hospital, Boston, MA, USA, between July 8, 2013, and Jan 13, 2014. Patients were included if they had moderate-to-severe ARDS as defined by the acute onset of the need for positive pressure ventilation by an endotracheal or tracheal tube, a PaO2:FiO2 less than 200 mm Hg with at least 8 cm H2O positive end-expiratory airway pressure (PEEP), and bilateral infiltrates consistent with pulmonary oedema on frontal chest radiograph. The first three patients were treated with low dose MSCs (1 million cells/kg predicted bodyweight [PBW]), the next three patients received intermediate dose MSCs (5 million cells/kg PBW), and the final three patients received high dose MSCs (10 million cells/kg PBW). Primary outcomes included the incidence of prespecified infusion-associated events and serious adverse events. The trial is registered with ClinicalTrials.gov, number NCT01775774.No prespecified infusion-associated events or treatment-related adverse events were reported in any of the nine patients. Serious adverse events were subsequently noted in three patients during the weeks after the infusion: one patient died on study day 9, one patient died on study day 31, and one patient was discovered to have multiple embolic infarcts of the spleen, kidneys, and brain that were age-indeterminate, but thought to have occurred before the MSC infusion based on MRI results. None of these severe adverse events were thought to be MSC-related.A single intravenous infusion of allogeneic, bone marrow-derived human MSCs was well tolerated in nine patients with moderate to severe ARDS. Based on this phase 1 experience, we have proceeded to phase 2 testing of MSCs for moderate to severe ARDS with a primary focus on safety and secondary outcomes including respiratory, systemic, and biological endpoints.The National Heart, Lung, and Blood Institute.

  • Biomarkers in acute respiratory distress syndrome: from pathobiology to improving patient care EXPERT REVIEW OF RESPIRATORY MEDICINE Walter, J. M., Wilson, J., Ware, L. B. 2014; 8 (5): 573-586

    Abstract

    Acute respiratory distress syndrome (ARDS) is a clinical syndrome characterized by alveolar flooding with protein-rich pulmonary edema fluid. Despite an improved understanding of ARDS pathogenesis, our ability to predict the development of ARDS and risk-stratify patients with the disease remains limited. Biomarkers may help identify patients at highest risk of developing ARDS, assess response to therapy, predict outcome, and optimize enrollment in clinical trials. This review begins with a general description of biomarker use in clinical medicine. We then review evidence that supports the value of various ARDS biomarkers organized by the cellular injury processes central to ARDS development: endothelial injury, epithelial injury, disordered inflammation and coagulation, fibrosis, and apoptosis. Finally, we summarize the growing contributions of genomic and proteomic research and suggest ways in which the field may evolve in the coming years.

  • Human mesenchymal stem cells reduce the severity of acute lung injury in a sheep model of bacterial pneumonia THORAX Asmussen, S., Ito, H., Traber, D. L., Lee, J. W., Cox, R. A., Hawkins, H. K., McAuley, D. F., McKenna, D. H., Traber, L. D., Zhuo, H., Wilson, J., Herndon, D. N., Prough, D. S., Liu, K. D., Matthay, M. A., Enkhbaatar, P. 2014; 69 (9): 819-825

    Abstract

    Human bone marrow-derived mesenchymal stem (stromal) cells (hMSCs) improve survival in mouse models of acute respiratory distress syndrome (ARDS) and reduce pulmonary oedema in a perfused human lung preparation injured with Escherichia coli bacteria. We hypothesised that clinical grade hMSCs would reduce the severity of acute lung injury (ALI) and would be safe in a sheep model of ARDS.Adult sheep (30-40?kg) were surgically prepared. After 5 days of recovery, ALI was induced with cotton smoke insufflation, followed by instillation of live Pseudomonas aeruginosa (2.5×10(11)?CFU) into both lungs under isoflurane anaesthesia. Following the injury, sheep were ventilated, resuscitated with lactated Ringer's solution and studied for 24?h. The sheep were randomly allocated to receive one of the following treatments intravenously over 1?h in one of the following groups: (1) control, PlasmaLyte A, n=8; (2) lower dose hMSCs, 5×10(6)?hMSCs/kg, n=7; and (3) higher-dose hMSCs, 10×10(6)?hMSCs/kg, n=4.By 24?h, the PaO2/FiO2 ratio was significantly improved in both hMSC treatment groups compared with the control group (control group: PaO2/FiO2 of 97±15?mm?Hg; lower dose: 288±55?mm?Hg (p=0.003); higher dose: 327±2?mm?Hg (p=0.003)). The median lung water content was lower in the higher-dose hMSC-treated group compared with the control group (higher dose: 5.0?g?wet/g dry [IQR 4.9-5.8] vs control: 6.7?g?wet/g dry [IQR 6.4-7.5] (p=0.01)). The hMSCs had no adverse effects.Human MSCs were well tolerated and improved oxygenation and decreased pulmonary oedema in a sheep model of severe ARDS.NCT01775774 for Phase 1. NCT02097641 for Phase 2.

  • OBLIQUE-AXIS VS. SHORT-AXIS VIEW IN ULTRASOUND-GUIDED CENTRAL VENOUS CATHETERIZATION JOURNAL OF EMERGENCY MEDICINE Wilson, J. G., Berona, K. M., Stein, J. C., Wang, R. 2014; 47 (1): 45-50

    Abstract

    Ultrasound (US) guidance during central venous catheterization (CVC) reduces complications and improves success rates compared to landmark-guided techniques. A novel "oblique view" (US transducer held at approximately 45° with respect to the target vessel) has been suggested to be superior to the standard short-axis approach usually used during US-guided CVC.The purpose of this study was to compare the rates of posterior vessel wall puncture (PVWP) between the short-axis and oblique-axis approaches to US-guided CVC.This was a prospective observational trial of emergency medicine residents and attending physicians, using gelatin models to simulate short-axis and oblique-axis US-guided CVC. Participants were blinded to the primary outcome of PVWP. Data collected included year in training/practice, number of central lines placed, time to successful "flash," and self-reported confidence of needle tip position using a Likert scale. After CVC simulation, models were deconstructed and inspected for PVWP.The rate of PVWP was 14.7% using short axis vs. 2.9% using oblique axis, resulting in a difference of 11.8% (95% confidence interval [CI] -4.7-28.3%, p = 0.10) and an odds ratio of 0.2 (95% CI 0.004-1.79). This difference was not statistically significant (p = 0.10). Mean time to flash was 11.9 s using short axis, and 15.4 s using oblique axis (p = 0.14). Confidence in needle tip location was 3.63 using short axis, and 4.58 using oblique axis (p < 0.001).We found decreased PVWP using the oblique axis approach, though the difference was not statistically significant, and participants felt more confident in their needle tip location using the oblique axis view. Further research into the potential benefits of the oblique axis approach is warranted.

  • Impaired Visual Fixation at the Age of 2 Years in Children Born Before the Twenty-Eighth Week of Gestation. Antecedents and Correlates in the Multi Center ELGAN Study PEDIATRIC NEUROLOGY Phadke, A., Msall, M. E., Droste, P., Allred, E. N., O'Shea, T. M., Kuban, K., Dammann, O., Leviton, A. 2014; 51 (1): 36-42

    Abstract

    Very little is known about the prevalence, antecedents, and correlates of impaired visual fixation in former very preterm newborns.In the multicenter ELGAN study sample of 1057 infants born before the twenty-eighth week of gestation who had a developmental assessment at 2 years corrected age, we identified 73 who were unable to follow an object across the midline. We compared them to the 984 infants who could follow an object across the midline.In this sample of very preterm newborns, those who had impaired visual fixation were much more likely than those without impaired visual fixation to have been born after the shortest of gestations (odds ratio, 3.2; 99% confidence interval, 1.4-7.5) and exposed to maternal aspirin (odds ratio, 5.2; 99% confidence interval, 2.2-12). They were also more likely than their peers to have had prethreshold retinopathy of prematurity (odds ratio, 4.1; 99% confidence interval, 1.8-9.0). At age 2 years, the children with impaired fixation were more likely than others to be unable to walk (even with assistance) (odds ratio, 7.5; 99% confidence interval, 2.2-26) and have a Mental Development Index more than three standard deviations below the mean of a normative sample (odds ratio, 3.6; 99% confidence interval, 1.4-8.2).Risk factors for brain and retinal damages, such as very low gestational age, appear to be risk factors for impaired visual fixation. This inference is further supported by the co-occurrence at age 2 years of impaired visual fixation, inability to walk, and a very low Mental Development Index.

  • Evolving practices in critical care and their influence on acute kidney injury CURRENT OPINION IN CRITICAL CARE Wilson, J. G., Butcher, B. W., Liu, K. D. 2013; 19 (6): 523-530

    Abstract

    This review highlights the principal advances in critical care over the past year, and discusses the impact of these advances on the diagnosis and management of acute kidney injury (AKI).Recent literature has focused on assessment of volume status and fluid management, particularly in the setting of respiratory and cardiac failure. Other critical care topics are reviewed using a system-based approach.The incidence of AKI appears to be increasing, and despite advances in the provision of critical care and renal replacement therapies, there has been little improvement in its associated morbidity and mortality. Nonetheless, recent advances in critical care will impact the diagnosis and management of AKI, as well as shape the future research agenda. Continued work in the fields of critical care and nephrology will undoubtedly be centered on improved biomarkers for the detection of AKI, specific therapies to mitigate or reverse AKI, and techniques to prevent the development of AKI in the critically ill population.
