RESUMEN

IMPORTANCE: Global cases of coronavirus disease 2019 infection continue to increase, and significant numbers of patients are critically ill, placing an immense burden on ICU resources. Understanding baseline resource needs and surge capacity in the ICU will be essential to meet current and projected healthcare needs. Continued appraisal of the state of readiness for healthcare systems at individual, regional and national levels will be paramount to ensure we are poised to continue the fight against coronavirus disease 2019. OBJECTIVES: This study queried U.S. ICU clinician perspectives on ICU preparedness and concerns regarding delivering coronavirus disease 2019 patient care. DESIGN SETTING AND PARTICIPANTS: An anonymous web-based survey administered from March 18, 2020, to March 25, 2020 (email and newsletter) used survey methodology to query members of U.S. national critical care organizations. MAIN OUTCOMES AND MEASURES: Through a 12-item descriptive questionnaire, ICU clinicians were assessed regarding preparedness, techniques employed to augment critical care capacity, and concerns related to caring for coronavirus disease 2019 patients. RESULTS: A total of 4,875 ICU clinicians responded to the survey. Respondents included ICU nurses (n = 3,470, 71.3%), physicians (n = 664, 13.6%), advanced practice providers (nurse practitioners and physician assistants; n = 334, 6.9%), respiratory therapists (n = 236, 4.9%), and pharmacists (n = 79, 1.6%). Over half (n = 2,552, 52.5%) reported having cared for a presumed or confirmed coronavirus disease 2019 patient. The majority (n = 4,010, 82.9%) identified that their hospital was employing techniques to augment critical care capacity. However, 64.5% (n = 3,125) believed that their ICU facility and team were inadequately prepared to treat coronavirus disease 2019 patients. The majority (n = 4,547, 93.9%) anticipated ICU personal protective equipment shortages based upon their current use profile. The chief reported concerns include ICU resource shortages such as supplies, medications, beds, ICU staffing shortages, and patient surge leading to overcrowding. CONCLUSIONS AND RELEVANCE: This national ICU clinician survey indicates that hospitals are expanding ICU bed capacity to prepare for coronavirus disease 2019 patient surge. Importantly, amid this preparation, ICU clinicians harbor concerns regarding preparedness, staffing, and common use resources that merit specific education as well as resource allocation and utilization planning.

RESUMEN

IMPORTANCE: Recent reports identify that among hospitalized coronavirus disease 2019 patients, 30% require ICU care. Understanding ICU resource needs remains an essential component of meeting current and projected needs of critically ill coronavirus disease 2019 patients. OBJECTIVES: This study queried U.S. ICU clinician perspectives on challenging aspects of care in managing coronavirus disease 2019 patients, current and anticipated resource demands, and personal stress. DESIGN, SETTING, AND PARTICIPANTS: Using a descriptive survey methodology, an anonymous web-based survey was administered from April 7, 2020, to April 22, 2020 (email and newsletter) to query members of U.S. national critical care organizations. MEASUREMENTS AND MAIN RESULTS: Through a 16-item descriptive questionnaire, ICU clinician perceptions were assessed regarding current and emerging critical ICU needs in managing the severe acute respiratory syndrome coronavirus 2 infected patients, resource levels, concerns about being exposed to severe acute respiratory syndrome coronavirus 2, and perceived level of personal stress. A total of 9,120 ICU clinicians responded to the survey, representing all 50 U.S. states, with 4,106 (56.9%) working in states with 20,000 or more coronavirus disease 2019 cases. The 7,317 respondents who indicated their profession included ICU nurses (n = 6,731, 91.3%), advanced practice providers (nurse practitioners and physician assistants; n = 334, 4.5%), physicians (n = 212, 2.9%), respiratory therapists (n = 31, 0.4%), and pharmacists (n = 30, 0.4%). A majority (n = 6,510, 88%) reported having cared for a patient with presumed or confirmed coronavirus disease 2019. The most critical ICU needs identified were personal protective equipment, specifically N95 respirator availability, and ICU staffing. Minimizing healthcare worker virus exposure during care was believed to be the most challenging aspect of coronavirus disease 2019 patient care (n = 2,323, 30.9%). Nurses report a high level of concern about exposing family members to severe acute respiratory syndrome coronavirus 2 (median score of 10 on 0-10 scale). Similarly, the level of concern reached the maximum score of 10 in ICU clinicians who had provided care to coronavirus disease 2019 patients. CONCLUSIONS: This national ICU clinician survey identifies continued concerns regarding personal protective equipment supplies with the chief issue being N95 respirator availability. As the pandemic continues, ICU clinicians anticipate a number of limited resources that may impact ICU care including personnel, capacity, and surge potential, as well as staff and subsequent family members exposure to severe acute respiratory syndrome coronavirus 2. These persistent concerns greatly magnify personal stress, offering a therapeutic target for professional organization and facility intervention efforts.

RESUMEN

A Caucasian woman aged 58 years with history of asthma and surgically repaired congenital diaphragmatic hernia presented to the emergency department (ED) with persistent cough, pleuritic chest pain, shortness of breath, in spite of recent treatment for influenza A virus. On physical examination, a large bulge was protruding from her left posterior thorax. She was found to have a large abnormal radiographic lucency on lateral chest X-ray posterior to the thoracic cavity, confirmed with chest CT to represent a large lung herniation in between the left seventh and eighth ribs. The patient was evaluated by a thoracic surgeon and offered surgical repair but ultimately decided on conservative management which to date has been ineffective.

RESUMEN

We report the case of a 23-year-old woman who presented with bloody diarrhoea and multiple syncopal events. While the initial diagnosis clinically appeared to be inflammatory bowel disease, she was found to have a portal vein thrombosis (PVT) on MR cholangiopancreatography and acute intestinal ischaemia on colonic biopsy. The aetiology of this patient's PVT is attributed to her acquired prothrombotic state from an estrogen-containing contraceptive pill in conjunction with regular tobacco use. Extensive mesenteric venous thrombosis from an acute PVT has been shown to cause intestinal ischaemia, likely from venous obstruction and reflexive arterial constriction; however, the diagnosis is often delayed until surgery or autopsy. Our case report highlights this patient's clinical presentation, workup and treatment, as part of a review for the risk factors and guidelines recommendations for management of an acute PVT.

RESUMEN

Atraumatic rupture of the normal spleen is a rare entity. Often, a triggering factor or minor physical event can be ascribed as the aetiology for rupture, including coughing, vomiting or minor medical procedures not involving the spleen. A 65-year-old man who was hospitalised for eosinophilic pneumonia developed haemodynamically unstable atrial flutter that necessitated urgent synchronised direct current cardioversion (DCCV). Two hours after successful cardioversion, he developed signs of an acute abdomen with free intraperitoneal fluid identified on bedside ultrasonography. Exploratory laparotomy revealed gross haemoperitoneum and splenic rupture requiring splenectomy. With exception of capsular defects and haemorrhage suggestive of organ rupture, the gross and histological examination of the spleen was otherwise unremarkable. The patient denied recent trauma. The cause of his spleen rupture was attributed to cardioversion and subsequent abdominal muscle contraction. This represents the first known case of splenic rupture associated with DCCV.

RESUMEN

A 55-year-old man undergoing chemotherapy for recurrent multiple myeloma presented with a 2-day history of bilateral lower leg rash with pain and oedema. On examination, there were numerous non-palpable retiform pruritic patches over both lower legs. Skin pnch biopsy demonstrated a diffuse interstitial neutrophilic infiltrate with necrosis. Peripheral blood and skin tissue cultures both isolated Citrobacterfreundii, consistent with a rare form of ecthyma gangrenosum. The patient responded with appropriate antibiotic therapy and removal of medical port. He made a full recovery from this infectious complication of his underlying immunosuppression.

RESUMEN

The Younger Dryas impact hypothesis posits that a cosmic impact across much of the Northern Hemisphere deposited the Younger Dryas boundary (YDB) layer, containing peak abundances in a variable assemblage of proxies, including magnetic and glassy impact-related spherules, high-temperature minerals and melt glass, nanodiamonds, carbon spherules, aciniform carbon, platinum, and osmium. Bayesian chronological modeling was applied to 354 dates from 23 stratigraphic sections in 12 countries on four continents to establish a modeled YDB age range for this event of 12,835-12,735 Cal B.P. at 95% probability. This range overlaps that of a peak in extraterrestrial platinum in the Greenland Ice Sheet and of the earliest age of the Younger Dryas climate episode in six proxy records, suggesting a causal connection between the YDB impact event and the Younger Dryas. Two statistical tests indicate that both modeled and unmodeled ages in the 30 records are consistent with synchronous deposition of the YDB layer within the limits of dating uncertainty (∼ 100 y). The widespread distribution of the YDB layer suggests that it may serve as a datum layer.

RESUMEN

OBJECTIVE: The Medicare Current Beneficiary Survey's (MCBS) Access to Care (ATC) file is designed to provide timely access to information on the Medicare population, yet because of the survey's complex sampling design and expedited processing it is difficult to use the file to make both "always-enrolled" and "ever-enrolled" estimates on the Medicare population. In this study, we describe the ATC file and sample design, and we evaluate and review various alternatives for producing "ever-enrolled" estimates. METHODS: We created "ever enrolled" estimates for key variables in the MCBS using three separate approaches. We tested differences between the alternative approaches for statistical significance and show the relative magnitude of difference between approaches. RESULTS: Even when estimates derived from the different approaches were statistically different, the magnitude of the difference was often sufficiently small so as to result in little practical difference among the alternate approaches. However, when considering more than just the estimation method, there are advantages to using certain approaches over others. CONCLUSION: There are several plausible approaches to achieving "ever-enrolled" estimates in the MCBS ATC file; however, the most straightforward approach appears to be implementation and usage of a new set of "ever-enrolled" weights for this file.

RESUMEN

Airbursts/impacts by a fragmented comet or asteroid have been proposed at the Younger Dryas onset (12.80 ± 0.15 ka) based on identification of an assemblage of impact-related proxies, including microspherules, nanodiamonds, and iridium. Distributed across four continents at the Younger Dryas boundary (YDB), spherule peaks have been independently confirmed in eight studies, but unconfirmed in two others, resulting in continued dispute about their occurrence, distribution, and origin. To further address this dispute and better identify YDB spherules, we present results from one of the largest spherule investigations ever undertaken regarding spherule geochemistry, morphologies, origins, and processes of formation. We investigated 18 sites across North America, Europe, and the Middle East, performing nearly 700 analyses on spherules using energy dispersive X-ray spectroscopy for geochemical analyses and scanning electron microscopy for surface microstructural characterization. Twelve locations rank among the world's premier end-Pleistocene archaeological sites, where the YDB marks a hiatus in human occupation or major changes in site use. Our results are consistent with melting of sediments to temperatures >2,200 °C by the thermal radiation and air shocks produced by passage of an extraterrestrial object through the atmosphere; they are inconsistent with volcanic, cosmic, anthropogenic, lightning, or authigenic sources. We also produced spherules from wood in the laboratory at >1,730 °C, indicating that impact-related incineration of biomass may have contributed to spherule production. At 12.8 ka, an estimated 10 million tonnes of spherules were distributed across ∼50 million square kilometers, similar to well-known impact strewnfields and consistent with a major cosmic impact event.

RESUMEN

BACKGROUND: Guillain-Barré syndrome (GBS) is a potentially life-threatening autoimmune disease causing demyelination of peripheral nerves. Multiple variants of GBS exist, with acute motor and sensory axonal neuropathy (AMSAN) being the most severe. GBS typically does not occur in the setting of other autoimmune diseases; however, few case reports do exist describing the occurrence. METHODS: We describe a patient with acute motor and sensory deficits and thrombocytopenia, ultimately diagnosed with concurrent AMSAN and immune thrombocytopenic purpura (ITP). RESULTS: A 75-year-old woman presented with new onset diplopia and gait instability, however, was found to have a severe thrombocytopenia. Corticosteroids were initiated for ITP and intravenous immunoglobulin for apparent GBS. Nerve conduction studies and her clinical course indicated that she likely had AMSAN. Although her platelet count recovered, her neurologic status remained poor, prompting therapy with plasmapheresis with subsequent mild improvement. CONCLUSION: A review of the literature revealed eleven previous cases of concurrent GBS and ITP; however, we report the first case of concurrent AMSAN and ITP. Among these cases, trends were noted to include sex, preceding infections, and cranial nerve involvement.

RESUMEN

Community-associated methicillin (meticillin)-resistant Staphylococcus aureus (CA-MRSA) continues to emerge as a cause of serious infections, chiefly of the skin and soft tissues. We present the first documented case of CA-MRSA mediastinitis in an adult. Blood and mediastinal isolates were characterized as CA-MRSA by pulsed-field gel electrophoresis and susceptibility testing.

RESUMEN

BACKGROUND: This study aimed to assess the efficacy of a method for avoiding conversion to laparotomy in patients considered for laparoscopic colectomy. Patients deemed to be at high risk for conversion to laparotomy were initially approached via an 8-cm midline incision ("peek port") with the laparoscopic equipment unopened. If intraperitoneal conditions were favorable, the procedure was performed using hand-assisted laparoscopy. If intraperitoneal conditions were unfavorable, the incision was extended to a formal laparotomy. Patients deemed to be at low risk for conversion to laparotomy were approached laparoscopically from the outset. METHODS: Data from 241 consecutive patients brought to the operating room for intended laparoscopic colectomy were retrieved from a prospective database. RESULTS: The study population consisted of 132 men and 109 women with a mean age of 62 years and a mean body mass index (BMI) of 28. Prior abdominal surgery had been performed in 49% of these patients. Inflammatory conditions accounted for 38% of the diagnoses, and enteric fistulas were present in 7% of the cases. Of the 25 patients who underwent the initial "peek port," 8 (32%) underwent immediate incision extension to formal laparotomy. Hand-assisted laparoscopic colectomy was performed in 17 (68%) of these 25 patients, with one subsequent conversion to formal laparotomy. Of the 216 patients initially approached laparoscopically, 5 (2%) required conversion to laparotomy. The laparotomy rate for the "peek port" group (9/25, 36%) was higher than for the initial laparoscopy group (5/216, 2%) (p < 0.0001). Of the 233 patients from both groups who underwent laparoscopy, the overall rate for conversion to laparotomy was 3% (6/233). CONCLUSIONS: The "peek port" approach to the patient with a potentially hostile abdomen allows for rapid assessment of intraperitoneal conditions and is associated with an overall low rate of conversion from laparoscopy to laparotomy. This technique should reduce overall cost by avoiding the use of laparoscopic equipment as well as potential complications related to trocar placement and laparoscopic dissection in patients who will ultimately require formal laparotomy.

RESUMEN

BACKGROUND: Lumbar peritoneal and ventriculoperitoneal shunts are widely used for the treatment of hydrocephalus. In the past, the abdominal portion of these procedures required laparotomy. With the advent of minimally invasive techniques, laparoscopically assisted placement of the distal catheter has been tried. MATERIALS AND METHODS: We performed 10 shunt procedures (3 lumbar peritoneal, 6 ventriculoperitoneal, and 1 meningomyelocele-peritoneal) in 10 patients (mean age 56; age range, 30-78 years). Four patients had undergone previous open shunt placement that failed. The abdominal portion of the procedure was performed using a 5-mm trocar and a 10Fr introducer for camera and catheter insertion. In 3 cases, an additional 5-mm port was necessary for lysis of adhesions. These access punctures did not require fascial closure and caused minimal pain and limitation. RESULTS: No intra- or postoperative complications were encountered in this small patient group. At a median follow-up of 50 months (range, 3-56 months) all patients had functioning shunts. CONCLUSION: Single trocar laparoscopically assisted placement of central nervous system-peritoneal shunts is safe and simple, and should be considered the procedure of choice. This technique is also suitable for repositioning migrated catheters and other catheter-tip manipulations.
