Are We Coping Well with COVID-19?: A Study on Its Psycho-Social Impact on Front-line Healthcare Workers.

BACKGROUND: Global pandemics have a profound psycho-social impact on health systems and their impact on healthcare workers is under-reported. METHODS: We performed a cross-sectional survey with 13 Likert-scale responses and some additional polar questions pertaining to dressing habits and learning in a university hospital in the midwest United States. Descriptive and analytical statistics were performed. RESULTS: The 370 respondents (66.1% response rate, age 38.5±11.6 years; 64.9% female), included 102 supervising providers [96 (25.9%) physicians, 6 (1.6%) mid-level], 64 (17.3%) residents/fellows, 73 (19.7% nurses, 45 (12.2%) respiratory therapists, 31 (8.4%) therapy services and others: 12 (3.2%) case-managers, 4 (1.1%) dietitians, 39 (10.5%) unclassified]. Overall, 200 (54.1%) had increased anxiety, 115 (31.1%) felt overwhelmed, 159 (42.9%) had fear of death, and 281 (75.9%) changed dressing habits. Females were more anxious (70.7% vs. 56%, X2 (1, N=292)=5.953, p=0.015), overwhelmed (45.6% vs. 27.3%, X2 (1, N=273)=8.67, p=0.003) and suffered sleep disturbances (52% vs. 39%, X2 (1, N=312)=4.91, p=0.027). Administration was supportive; 243 (84.1%, N=289), 276 (74.5%) knew another co-worker with COVID-19, and only 93 (25.1%) felt healthcare employment was less favorable. Residents and fellows reported a negative impact on their training despite feeling supported by their program. CONCLUSION: Despite belief of a supportive administration, over half of healthcare workers and learners reported increased anxiety, and nearly a third felt overwhelmed during this current pandemic.

Imported Infections in Rural Mid-West United States - A Report from a Tertiary Care Center.

BACKGROUND: There is lack of specific data on imported infections in the mid-west United States (U.S.). METHODS: Retrospective data on demographic and geographic data of imported infections seen by the infectious diseases clinics and consultation service from 2001-2018 was collected. RESULTS: Of the 64 infections, tuberculosis(TB) was most common [20(31.3%); pulmonary(11,55%), lymphadenopathy(8,40%), gastrointestinal(4,20%), disseminated(2,10%), and 1(5%) each of genitourinary and vertebral spine infection, 4 Human immune-deficiency virus infection and 1 echinococcosis)] followed by malaria(11,17.2%). Other infections: Cysticercosis [7,10.9%], giardiasis (4,6.3%), 3 each (4.7%) Human T-lymphotrophic Virus infection and schistosomiasis, 2 each (3.1%) leprosy, strongyloidiasis, and typhoid fever, one each (1.6%) of ascariasis, brucellosis, Chagas disease, Chikungunya virus, hepatitis A virus, echinococcosis, Japanese encephalitis virus, loiasis, paratyphoid fever, Q fever, and unspecified parasitosis. Geographic origins: Africa(26,40.6%), Asia(16,25%), Central America(11,17.2%), Europe(2,3.1%), Oceania(2,3.1%), South America(2,3.1%), and Unknown(5). More cases were seen after 2015. CONCLUSIONS: With increasing tourism, it is important to educate rural mid-west healthcare professionals on travel medicine. The current COVID-19 pandemic illustrates the importance of this type of education and data accumulation now and in the future.

Laboratory Tests for COVID-19: A Review of Peer-Reviewed Publications and Implications for Clinical Use.

Diagnostic tests for the coronavirus infection 2019 (COVID-19) are critical for prompt diagnosis, treatment and isolation to break the cycle of transmission. A positive real-time reverse-transcriptase polymerase chain reaction (RT-PCR), in conjunction with clinical and epidemiologic data, is the current standard for diagnosis, but several challenges still exist. Serological assays help to understand epidemiology better and to evaluate vaccine responses but they are unreliable for diagnosis in the acute phase of illness or assuming protective immunity. Serology is gaining attention, mainly because of convalescent plasma gaining importance as treatment for clinically worsening COVID-19 patients. We provide a narrative review of peer-reviewed research studies on RT-PCR, serology and antigen immune-assays for COVID-19, briefly describe their lab methods and discuss their limitations for clinical practice.

A Quality Improvement Initiative: Developing a Multi-Disciplinary Team for Infective Endocarditis.

BACKGROUND: As guidelines do not describe how to develop a multi-disciplinary team(MDT), we provide a model using quality improvement tools to design a MDT for infective endocarditis (IE). METHODS: Primary service, specialty teams and whether they had surgery or not (indications, reasons, outcomes and complications) were recorded for IE patients for January-December 2016. Criteria: age >18years and definite IE per modified Duke criteria. RESULTS: Of all cases, 29/82 met criteria. Primary service: internal medicine 18(62.1%), medical intensive care and cardiology 4(13.8%) each, family medicine 2(7.9%) and pediatrics 1(3.4%). Surgery was indicated in 21(72.4%), 9 (42.9%) underwent surgery, 12 (57.1%) did not [6/9(66.67%) left side IE died, all right side IE (3,25%) survived] and 2 (22.2%) had missed opportunities and this was chosen as the leverage point. MDT was developed to reduce the number of left sided IE patients not undergoing surgery despite indications. CONCLUSIONS: Quality improvement and team development tools help in developing MDT for IE.

Early diagnosis of Ehrlichia ewingii infection in a lung transplant recipient by peripheral blood smear.

Ehrlichiosis in lung transplant (LT) recipients is associated with severe outcomes. Ehrlichia ewingii is a less frequent cause of symptomatic ehrlichiosis, characterized by cytoplasmic inclusions (morulae) within circulating neutrophils. We report a case of E. ewingii infection in an LT recipient diagnosed promptly by blood smear exam and confirmed with molecular studies.

Is It Painful to Manage Chronic Pain? A Cross-Sectional Study of Physicians In-Training in a University Program.

BACKGROUND: Prescribing opioids for chronic non-cancer pain (CNCP) is a challenge due to associated risks from abuse, addiction and adverse effects. We surveyed resident physicians on their knowledge, attitude and practices in opioid prescription practices in the ambulatory setting and conducted an educational module to address their knowledge gaps. METHODS: A phase 1 survey assessed knowledge, attitudes and practices of residents in the out-patient management of CNCP with opioids. Demographics, numbers of patients seen, those with concerns for risky behaviors, adverse effects and the reasons for concern were also recorded. In Phase 2, an educational module in the form of didactics and case based discussions addressed the perceived deficiencies noted from results of phase 1 survey. Pre and post module surveys assessed the effectiveness of the educational module. RESULTS: In the phase 1 study (45/49, 92% response rate, M:F = 30:15) 33.3% (15/45) were in Post-Graduate Year (PGY) 1, 35.6% (16/45) PGY2s and 31.1% (14/45) PGY3s; 80% (36/45) saw more than one patient with CNCP in the previous 3 months; 62.2% (28/45) had at least one patient with concerns for misuse and addiction; 77.8% (35/45) and 86.7% (39/45) reported a lack of training and consistent documentation respectively, and 82.2% (37/45) were uncomfortable to refill for other provider's patients. All (100%, 45/45) consulted the clinical pharmacist; 86.7% (39/45) believed that either focused education would be beneficial. In the phase 2 study (44/49, 89.7% response rate, M: F = 29: 15), the pre- and post-module responses showed that > 90% of the residents perceived improvement in knowledge and confidence in management of CNCP with opioids after the educational module. CONCLUSIONS: Internal medicine residents perceived deficits in their ability to manage CNCP. Following a focused educational training, residents' knowledge and confidence in prescription of opioids improved, demonstrating the need to include management of CNCP with opioids into their curriculum.

Severe Community-Acquired Pneumonia with Bacteremia Caused by Herbaspirillum aquaticum or Herbaspirillum huttiense in an Immune-Competent Adult.

Herbaspirillum spp. are Gram-negative bacteria that inhabit soil and water. Infections caused by these organisms have been reported in immunocompromised hosts. We describe severe community-acquired pneumonia and bacteremia caused by Herbaspirillum aquaticum or H. huttiense in an immunocompetent adult male.

Validation of a Novel, Rapid Sepsis Diagnostic for Emergency Department Use.

OBJECTIVES: To assess the in vitro IntelliSep test, a microfluidic assay that quantifies the state of immune activation by evaluating the biophysical properties of leukocytes, as a rapid diagnostic for sepsis. DESIGN: Prospective cohort study. SETTING: Five emergency departments (EDs) in Louisiana, Missouri, North Carolina, and Washington. PATIENTS: Adult patients presenting to the ED with signs (two of four Systemic Inflammatory Response Syndrome criteria, where one must be temperature or WBC count) or suspicion (provider-ordered culture) of infection. INTERVENTIONS: All patients underwent testing with the IntelliSep using ethylene diamine tetraacetic acid-anticoagulated whole blood followed by retrospective adjudication for sepsis by sepsis-3 criteria by a blinded panel of physicians. MEASUREMENTS AND MAIN RESULTS: Of 599 patients enrolled, 572 patients were included in the final analysis. The result of the IntelliSep test is reported as the IntelliSep Index (ISI), ranging from 0.1 to 10.0, divided into three interpretation bands for the risk of sepsis: band 1 (low) to band 3 (high). The median turnaround time for ISI results was 7.2 minutes. The ISI resulted band 1 in 252 (44.1%), band 2 in 160 (28.0%), and band 3 in 160 (28.0%). Sepsis occurred in 26.6% (152 of 572 patients). Sepsis prevalence was 11.1% (95% CI, 7.5-15.7%) in band 1, 28.1% (95% CI, 21.3-35.8%) in band 2, and 49.4% (95% CI, 41.4-57.4%) in band 3. The Positive Percent Agreement of band 1 was 81.6% and the Negative Percent Agreement of band 3 was 80.7%, with an area under the receiver operating characteristic curve of 0.74. Compared with band 1, band 3 correlated with adverse clinical outcomes, including mortality, and resource utilization. CONCLUSIONS: Increasing ISI interpretation band is associated with increasing probability of sepsis in patients presenting to the ED with suspected infection.

Impact of a nutrition support therapy on hospital-acquired infections: A value analysis.

BACKGROUND: Hospital-acquired conditions (HACs) have a direct impact on value, as they decrease quality and increase costs. Numerous interventions have been tried, including nutrition support therapy, with unknown effect on value. Therefore, a value analysis of nutrition support therapy on HACs was performed. METHODS: An extensive literature search was performed. Using the Medicare Parts A and B Claims 5% Sample data set, analytic claims modeling was conducted. RESULTS: The search identified 1099 studies, with eight meeting the inclusion criteria. All studies were performed on adult critically ill patients and focused on HA infections (HAIs) as the HAC. One study underwent Medicare claims modeling and revealed nutrition therapy has the potential of saving at least $104 million annually in Medicare patients with HAIs. CONCLUSION: Nutrition support therapy has the potential to reduce costs of Medicare spending in respect to HAIs.

Coronavirus Disease 2019 Pandemic as Catalyst for Telemedicine Adoption: A Single-Center Experience.

Background: Telemedicine use has increased due to stay-at-home orders during the novel coronavirus 2019 pandemic. We explored ambulatory provider's perception on telemedicine. Methods: An anonymized survey was e-mailed to physicians and midlevel providers of our university hospital ambulatory clinics to assess current use, preferences for future use, and satisfaction with televisits. Results: Of all providers, 249 responded (response rate 24%, 121 [48.6%] men, 177 [71.1%] attending physicians, 43 [17.2%] trainees, and 29 [11.6%] midlevel providers). Most respondents (120, 48.2%) belonged to subspecialties in medicine. At the time of the survey, 168 (67.5%) were using telemedicine for less than half of all visits and had video capabilities, of whom 224 (90%) considered it to be effective for return visits and 37 (15%) perceived it to be effective for new patients, 217 (87.1%) wanted to continue with telemedicine practice, and 113 (45.4%) preferred to use telemedicine for more than a quarter of their future patients even after the pandemic. Most (194 [77.9%]) were satisfied with telemedicine and we found no differences among specialties. Those with audio-only visits reported least effectiveness for new patient evaluation (p < 0.001) and overall provider satisfaction (p = 0.02) when compared with others. Those who saw more than a quarter of their patients through televisits desired to increase their future televisits to >50% including new patients (p < 0.001). Conclusions: There is widespread interest in telemedicine in all specialties. Acceptance is high for return visits, but low for new patient visits. Improvement in technology to have both audio and video capability consistently may foster further interest toward increasing telemedicine in the future.

Calciphylaxis: An Analysis of Concomitant Factors, Treatment Effectiveness and Prognosis in 30 Patients.

BACKGROUND: Calciphylaxis is a rare but severe complication mostly affecting patients with end-stage renal disease (ESRD) and is associated with high morbidity and mortality. The natural history, concomitant factors, pathogenesis, and treatment for calciphylaxis remain equivocal. METHODS: We conducted a retrospective study on patients diagnosed with calciphylaxis in a tertiary care center between January 1, 2012, and December 31, 2017. We describe demographics, co-morbidities, laboratory parameters, effectiveness of sodium thiosulfate treatment and outcomes. RESULTS: Of the 30 patients (age 65.6 ± 12.79 years, male:female = 8:22), 23 (76.67%) had ESRD and were either on hemodialysis (15 [65.22%], median duration 22.5 months [range 0.2-96 months]) or peritoneal dialysis (8 [34.78%], duration 29±10 months). Predisposing home medications: 8 (28%) had calcium supplements, 10 (36%) had warfarin, 16 (57%) had vitamin D and 5 (18%) had iron supplements. The median parathyroid hormone (PTH) level was 239.8 pg/mL (range 4.7-2922). Calciphylaxis was found on extremities in 21 (70%) and on torso in 6 (20%) patients. Sodium thiosulfate (STS) was given for treatment in 20 (67%) patients and 3 were cured in <2.25 months. One-year survival for all patients with calciphylaxis was 26% (29% for STS group and 20% for those that did not receive STS) and following any surgical treatment regardless of STS use was 14%. LIMITATIONS: Retrospective design, absence of a control group and low power. CONCLUSION: Calciphylaxis was more common among females with a predilection for extremities over the torso. Elevations in PTH and inflammatory markers were common. Treatment with STS did not show a statistically significant improvement in survival. Those who were cured, were treated with STS up to three months.

Ehrlichiosis Presenting as Hemophagocytic Lymphohistiocytosis in an Immunocompetent Adult.

Hemophagocytic Lymphohistiocytosis (HLH) is a fatal, immunologic syndrome characterized by dysregulated tissue inflammation. HLH can be either primary or secondary; with the latter typically resulting from an infection. Diagnosis requires five or more of the following: fever, splenomegaly, cytopenia, hypertriglyceridemia, hemophagocytosis via biopsy, low natural killer (NK) cell activity, elevated ferritin and soluble CD25 level (sCD25). We present a case of HLH related to ehrlichiosis. In order to mount an effective immune response against microbes such as Ehrlichia chaffeensis, the host must have preserved NK cell function. Being that HLH Is characterized as a state of depleted NK cell function, It is crucial to investigate the role NK cell function has in the setting of HLH on the infectivity of Ehrlichia species.

Technical efficiency, short-term clinical results and safety of a large-bore aspiration catheter in acute pulmonary embolism - A retrospective case study.

BACKGROUND: Mechanical thrombectomy plays an important role in the management of acute pulmonary embolism (PE), either when rapid clot dissolution is needed or when thrombolytics are contraindicated. We describe our clinical and technical experience with the FlowTriever mechanical thrombectomy device in patients with acute PE. MATERIALS AND METHODS: A retrospective analysis was performed on all cases of acute PE treated with the FlowTriever device at a single tertiary care hospital system during the trial period (November 2019-January 2020). Technical and clinical results, including complications, are reported. RESULTS: Technical success was achieved in all eight successive cases (seven cases of submassive and 1 case of massive PE). Mean pulmonary artery pressure (MPAP) improved significantly after mechanical thrombectomy (27.8 ± 6.4 mmHg preprocedure; 20.5 ± 3.8 mmHg postprocedure; 7.3 ± 5.2 mmHg decrease after the procedure; P = 0.016). Hemoglobin levels did not change significantly after mechanical thrombectomy (11.8 g/dl ± 3.4 preprocedure; 9.9 g/dl ± 2.1 postprocedure; P = 0.20). Reduction in MPAP was achieved in 88% of cases (7/8) and hypoxia improved in all the nonintubated patients (7/7). Mortality observed in one patient with a massive central PE, was not related to the procedure. No mortality or procedural complications were observed in patients with submassive PE. CONCLUSIONS: The positive initial clinical experience and safety profile using the FlowTriever in the treatment of acute PE suggests, it has the potential to fill the unmet needs of a good mechanical thrombectomy device to treat massive and submassive high-risk PE especially when thrombolytics are contraindicated.

Ultra-protective mechanical ventilation without extra-corporeal carbon dioxide removal for acute respiratory distress syndrome.

BACKGROUND: Tidal hyperinflation can still occur with mechanical ventilation using low tidal volume (LVT) (6 mL/kg predicted body weight (PBW)) in acute respiratory distress syndrome (ARDS), despite a well-demonstrated reduction in mortality. METHODS: Retrospective chart review from August 2012 to October 2014. Inclusion: Age >18years, PaO2/FiO2<200 with bilateral pulmonary infiltrates, absent heart failure, and ultra-protective mechanical ventilation (UPMV) defined as tidal volume (VT) <6 mL/kg PBW. Exclusion: UPMV use for <24 h. Demographics, admission Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, arterial blood gas, serum bicarbonate, ventilator parameters for pre-, during, and post-UPMV periods including modes, VT, peak inspiratory pressure (PIP), plateau pressure (Pplat), driving pressure, etc. were gathered. We compared lab and ventilator data for pre-, during, and post-UPMV periods. RESULTS: Fifteen patients (male:female = 7:8, age 42.13 ± 11.29 years) satisfied criteria, APACHEII 20.6 ± 7.1, mean days in intensive care unit and hospitalization were 18.5 ± 8.85 and 20.81 ± 9.78 days, 9 (60%) received paralysis and 7 (46.67%) required inotropes. Eleven patients had echocardiogram, 7 (63.64%) demonstrated right ventricular volume or pressure overload. Eleven patients (73.33%) survived. During-UPMV, VT ranged 2-5 mL/kg PBW(3.99 ± 0.73), the arterial partial pressure of carbon dioxide (PaCO2) was higher than pre-UPMV values (84.81 ± 18.95 cmH2O vs. 69.16 ± 33.09 cmH2O), but pH was comparable and none received extracorporeal carbon dioxide removal (ECCO2-R). The positive end-expiratory pressure (14.18 ± 7.56 vs. 12.31 ± 6.84 cmH2O), PIP (38.21 ± 12.89 vs. 32.59 ± 9.88), and mean airway pressures (19.98 ± 7.61 vs. 17.48 ± 6.7 cm H2O) were higher during UPMV, but Pplat and PaO2/FiO2 were comparable during- and pre-UPMV. Driving pressure was observed to be higher in those who died than who survived (24.18 ± 12.36 vs. 13.42 ± 3.25). CONCLUSION: UPMV alone may be a safe alternative option for ARDS patients in centers without ECCO2-R.

Optic neuritis caused by the re-emerging great masquerader.

A 49-year-old Caucasian woman presented with subacute headache and right eye pain associated with scotoma, blurred vision and photophobia. MRI was suggestive of optic neuritis of the right optic nerve and she was treated with steroids. Due to persistent symptoms, a lumbar puncture was performed and cerebrospinal fluid analysis was positive for venereal disease research laboratory and rapid plasma reagin titres. On further history, she recalled experiencing an illness associated with diffuse rash, likely secondary syphilis, 1-2 months prior. She tested negative for HIV. She was treated with intravenous penicillin for 2 weeks following which she experienced improvement in symptoms.

Disseminated histoplasmosis in a patient with common variable immunodeficiency: A coincidence or the result of T cell defects?

BACKGROUND: In endemic regions, histoplasmosis is often seen in hosts with defective cell mediated immunity. We report a case of disseminated histoplasmosis in a patient with common variable immunodeficiency (CVID), a disorder mainly characterized by B cell defects. CASE: A 35 year old male with CVID developed fever, headache, dyspnea and pancytopenia within few weeks of swimming in the Tennessee River. After a non-revealing initial evaluation he was transferred to a tertiary facility for fever of unknown origin, where massive splenomegaly was noted. Clinical course was complicated by hypoxia from extensive bilateral lung infiltrates requiring non-invasive ventilation. Urine and serum Histoplasma antigens were positive. He was treated with liposomal amphotericin B followed by itraconazole after clinical improvement within 48 h and discharged home by day 6. Fungal blood cultures sent on day 1 grew Histoplasma capsulatum on day 19. After 5 months splenomegaly completely resolved and he successfully completed one year of treatment with itraconazole. CONCLUSIONS: Our case highlights the significance of T cell defects in CVID. More research focusing on T cell defects in CVID is required to understand the extent of vulnerability to such intracellular pathogens in CVID.

Primary cytomegalovirus infection in immunocompetent adults in the United States - A case series.

Primary Cytomegalovirus (CMV) infection is often not suspected as a cause of fever of unknown origin (FUO) in immune-competent adults. We present a case-series of symptomatic primary CMV infection in immunocompetent adults presenting as fever of unknown origin (FUO). All patients with CMV serology tested between November 2008 and June 2016 underwent chart review. Cases were defined as those between 18 and 65 years of age with documented fever and elevated serum anti-CMV IgM. Exclusion criteria were organ specific CMV disease, positive serum anti-EBV IgM, or presence of any immunocompromising condition. Sixteen patients (69% male, mean age 42.2 ± 11.7 years) met criteria. Mean duration of illness was 4.6 ± 3.3 weeks. Common symptoms other than fever included fatigue (94%), night sweats (81%), malaise (75%), myalgias (63%), and headache (56%). Eleven patients (68.8%) had contact with young children; six (35.3%) patients had children in daycare. Twelve (75%) patients had extensive testing and multiple visits or hospitalizations prior to consulting with an infectious disease specialist. Peripheral smear was done in twelve (75%) patients and all had atypical lymphocytes. Five patients (31.3%) had a leukocytosis. Peak serum transaminases were: AST 115.25 ± 50.5 IU/L and ALT 168.38 ± 92.0 IU/L. One patient had splenic infarcts. In addition, two cases of hydrops fetalis were attributed to primary CMV infection. In summary, primary CMV infection can present as FUO in immunocompetent adults. Contact with young children in daycare may be a risk factor. Heightened clinical suspicion will promote earlier diagnosis and avoid unnecessary testing.
