Background: Takotsubo syndrome (TTS) is a non-ischemic cardiomyopathy characterized by an acute reversible left ventricular dysfunction with typical apical ballooning, usually with subsequent complete spontaneous recovery. TTS may be triggered by several physical and emotional stressors. The name Covidsubo was recently adopted to describe this emerging entity. TTS during quarantine may be a reasonable outcome of the overwhelming stress and fear of this pandemic. However, according to the current literature, conflicting results have been reported regarding the incidence of this syndrome during the first wave of the pandemic, and further studies are needed. High index of suspicion is needed to identify patients during the next waves of the pandemic, particularly given the need for minimizing imaging modalities and contact with the patients.

Objectives: To describe two cases of TTS triggered by quarantine during the coronavirus disease-2019 (COVID-19) pandemic.

Methods: Two patients (age 81 years and 70 years) were admitted to our medical center with severe chest pain with normal blood pressure and heart rate.

Results: TTS should always be in the differential diagnosis in patients presenting with chest pain suspected to be from coronary origin. Based on the typical clinical, echocardiographic, and angiographic findings, we assumed TTS.

Conclusions: The only prominent stressor in the two cases in this article was the stress accompanying quarantine.

Background: Immune cell counts in blood in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection may be useful prognostic biomarkers of disease severity, mortality, and response to treatment.

Objectives: To analyze sub-populations of lymphocytes at hospital admission in survivors and deceased from severe pneumonia due to coronavirus disease-2019 (COVID-19).

Methods: We conducted a cross-sectional study of healthcare workers confirmed with SARS-CoV-2 in convalescents (control group) and healthy controls (HC) diagnosed with severe COVID-19. Serum samples were taken at hospital admission and after recovery. Serum samples ≥ 25 days after onset of symptoms were analyzed for lymphocyte subpopulations through flow cytometry. Descriptive statistics, Kruskall-Wallis test, receiver operating characteristic curve, calculation of sensitivity, specificity, predictive values, and Kaplan-Meier analysis were performed.

Results: We included 337 patients: 120 HC, 127 convalescents, and 90 severe COVID-19 disease patients (50 survivors, 40 deceased). For T cells, total lymphocytes ≥ 800/μL, CD3+ ≥ 400/μL, CD4+ ≥ 180/μL, CD8+ ≥ 150/μL, B cells CD19+ ≥ 80/μL, and NK ≥ 34/μL subsets were associated with survival in severe COVID-19 disease patients. All subtypes of lymphocytes had higher concentrations in survivors than deceased, but similar between HC and convalescents. Leukocytes ≥ 10.150/μL or neutrophils ≥ 10,000/μL were associated with increased mortality. The neutrophil-to-lymphocyte ratio (NLR) ≥ 8.5 increased the probability of death in severe COVID-19 (odds ratio 11.68).

Conclusions: Total lymphocytes; NLR; and levels of CD3+, CD4+, CD8+, and NK cells are useful as biomarkers of survival or mortality in severe COVID-19 disease and commonly reach normal levels in convalescents.

Background: Pancreatic trauma is uncommon in pediatric patients and presents diagnostic and therapeutic challenges. While non-operative management (NOM) of minor pancreatic injuries is well accepted, the management of major pancreatic injuries remains controversial.

Objectives: To evaluate management strategies for major blunt pancreatic injury in children.

Methods: Data were retrospectively collected for all children treated for grade III or higher pancreatic injury due to blunt abdominal trauma from 1992 to 2015 at two medical centers. Data included demographics, mechanism of injury, laboratory and imaging studies, management strategy, clinical course, operative findings, and outcome.

Results: The cohort included seven boys and four girls aged 4–15 years old (median 9). Six patients had associated abdominal (mainly liver, n=3) injuries. The main mechanism of injury was bicycle (handlebar) trauma (n=6). Five patients had grade III injury and six had grade IV. The highest mean amylase level was recorded at 48 hours after injury (1418 U/L). Management strategies included conservative (n=5) and operative treatment (n=6): distal (n=3) and central (n=1) pancreatectomy, drainage only (n=2) based on the computed tomography findings and patient hemodynamic stability. Pseudocyst developed in all NOM patients (n=5) and two OM cases, and one patient developed a pancreatic fistula. There were no differences in average length of hospital stay.

Conclusions: NOM of high-grade blunt pancreatic injury in children may pose a higher risk of pseudocyst formation than OM, with a similar hospitalization time. However, pseudocyst is a relatively benign complication with a high rate of spontaneous resolution with no need for surgical intervention.

Hospitalization of ulcerative colitis patients is needed in severe exacerbation of the disease or for managing complications. In this systematic review and meta-analysis the prevalence of hospitalization in ulcerative colitis and possible predictive factors are discussed. A systematic literature search of English language publications that were published before 31 December 2019 was conducted. Retrospective cohort studies describing hospitalizations of UC patients were included. Meta-analysis was performed by using comprehensive meta-analysis software. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated for the number of patients hospitalized. Seven studies and 15 datasets were found that fulfilled the inclusion criteria. In total, the studies included 2067 patients from six countries. The event rates for the number of patients hospitalized in a follow-up duration of 42,320 patient-years and for the number of patients underwent operation in a follow-up of 24,650 patient-years were 0.065 (95%CI 0.063–0.068) and 0.019 (95%CI 0.017–0.021), respectively. More studies during the era of biologics need to be performed to identify the factors predictive of hospitalization and surgery with UC. Prevention of inflammation and UC complications may prevent hospitalization and the need for surgical treatment

Background: Peritoneal dialysis (PD) is a treatment option for patients with end-stage renal disease (ESRD) and cardiorenal syndrome (CRS).

Objectives: To evaluate the outcome of this patient population.

Methods: A retrospective study was conducted of patients who underwent an open or laparoscopic insertion of a PD catheter at our institution between 2009 and 2017. Data included demographics, peri-operative parameters, and long-term outcome. Patient and technique survival curves are presented, including subgroup analysis by method of catheter insertion and techniques for infection prevention.

Results: The study population included 95 men and 42 women, aged 65.7 ± 12.4 years. Mean follow-up was 34.6 ± 27.3 months. Open insertion was performed in 113 cases, while 24 underwent laparoscopic insertion. There was no difference in technique survival between these groups (P = 0.943). Removal of the catheter was required in 66% of patients. Median technique survival was 12.1 months. Two-year technique survival was 37% and 5-year technique survival was 12%. The leading cause for catheter removal was infection (69%). Application of measures for prevention of infections were significantly associated with prolonged technique survival (P = 0.001). Technique survival after 2 years was 38% with the application of a single measure and 57% with the application of two measures (P = 0.001). CRS patients (n=24) had a significantly lower overall survival rate (2-year survival 20% vs. 74%, P = 0.001).

Conclusions: The method of catheter insertion has no effect on technique survival. Prevention of infections is the most significant factor for improving the technique survival rates.

Background: The coronavirus disease-2019 (COVID-19) crisis has affected how hospitals work and has had an effect on orthopedic surgery.

Objectives: To compare patient management and low-energy and high-energy trauma treatment at two orthopedic trauma units during the COVID-19 crisis and to clarify resource demands and preparedness in orthopedic clinics during the state of emergency caused by the COVID-19 pandemic.

Methods: This retrospective study was conducted at two orthopedic trauma units from 14 March 2019 to 14 April 2019 and from 14 March 2020 to 14 April 2020.

Results: The proportion of patients admitted in the multi-trauma orthopedic unit decreased by one-third, the mean time interval from admission to surgery significantly decreased, and the number of surgeries and mean length of stay in hospital decreased in 2020 compared to the same test period in 2019. In the orthopedic trauma unit, the number of patients and surgeries also decreased.

Conclusions: Our study highlights changes in orthopedic injury characteristics in two orthopedic units during the COVID-19 crisis in Latvia and compares these changes to data from the same time period one year earlier.

Background: The novel coronavirus disease (COVID-19) pandemic changed medical environments worldwide.

Objectives: To evaluate the impact of the COVID-19 pandemic on trauma-related visits to the emergency department (ED).

Methods: A single tertiary center retrospective study was conducted that compared ED attendance of patients with injury-related morbidity between March 2020 (COVID-19 outbreak) and pre-COVID-19 periods: February 2020 and the same 2 months in 2018 and 2019.

Results: Overall, 6513 patients were included in the study. During the COVID-19 outbreak, the daily number of patients visiting the ED for acute trauma declined by 40% compared to the average in previous months (P < 0.01). A strong negative correlation was found between the number of trauma-related ED visits and the log number of confirmed cases of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Israel (Pearson's r = -0.63, P < 0.01). In the COVID-19 period there was a significant change in the proportion of elderly patients (7% increase, P = 0.002), admissions ratio (12% increase, P < 0.001), and patients brought by emergency medical services (10% increase, P < 0.001). The number of motor vehicle accident related injury declined by 45% (P < 0.01).

Conclusions: A significant reduction in the number of trauma patients presenting to the ED occurred during the COVID-19 pandemic, yet trauma-related admissions were on the rise

Background: Takotsubo syndrome (TTS) is a non-ischemic cardiomyopathy characterized by an acute reversible left ventricular dysfunction with typical apical ballooning, usually with subsequent complete spontaneous recovery. TTS shares several features with acute coronary syndrome (ACS), including clinical presentation, ECG changes, and elevated troponin.

Objectives: To identify different features that may help differentiate between TTS and ACS with presentation based on presenting symptoms and physical examination.

Methods: We compared 35 patients who TTS had been diagnosed with 60 age- and sex- matched patients with ACS (both ST and non-ST segment elevation myocardial infarction) who were hospitalized in Galilee Medical Center through 2011-2015.Basic characteristics and clinical features of the two groups were compared using appropriate statistical tests.

Results: Of the patients with TTS, 21 (60%) reported an emotional trigger (60%) before admission, although they did not have increased prevalence of psychiatric disease compared to ACS patients (5.7% vs. 5%, P = 0.611). There was no difference in the type of chest pain or accompanied symptoms between the groups. Of notice, ECG changes in the TTS group were prominent in the anterior leads, and the patients presented with higher heart rate (86 ± 17 vs. 79 ± 15, P = 0.029) and lower systolic blood pressure (129 ± 26 vs. 142 ± 30, P = 0.034) on admission compared to the ACS group.

Conclusions: There was no reliable feature that could distinguish TTS from ACS based on clinical presentation. TTS should always be in the differential diagnosis in patients with acute chest pain, especially in elderly women

Background: During the coronavirus disease-2019 (COVID-19) pandemic outbreak our blood bank developed protocols to guarantee accurate blood components to COVID-19 patients.

Objectives: To provide convalescent whole blood donor screening strategies for patients recovering from COVID-19.

Methods: We recruited COVID-19 recovering patients who met our defined inclusion criteria for whole blood donation. All blood units were screened for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RNA by real time reverse transcription polymerase chain reaction (RT-PCR) and SARS-COV-2 immunoglobulin G (IgG) antibodies against the S1 domain.

Results: We screened 180 blood units from patients recovering from COVID-19. All results were negative for SARS-CoV-2 RNA and 87.2% were positive for SARS-COV-2 IgG antibodies in the plasma.

Conclusions: Blood component units from recovering COVID-19 patients are safe. Plasma units with positive IgG antibodies could serve as an efficient passive immunization for COVID-19 patients. Moreover, in the face of increased transfusion demand for treatment of anemia and coagulation dysfunction in critical ill COVID-19 patients, red blood cells units and random platelets units from convalescent donors can be safely transfused.
