- Abstract
Bio-mapping studies play an important role, as the data collected can be managed and analyzed in multiple ways to look at process trends, find explanations about the effect of process changes, activate a root cause analysis for events, and even compile performance data to demonstrate to inspection authorities or auditors the effect of certain decisions made on a daily basis and their effects over time in commercial settings not only from the food safety perspective but also from the production side. This study presents an alternative analysis of bio-mapping data collected throughout several months in a commercial poultry processing operation as described in the article "Bio-Mapping Indicators and Pathogen Loads in a Commercial Broiler Processing Facility Operating with High and Low Antimicrobial Interventions". The conducted analysis identifies the processing shift effect on microbial loads, attempts to find correlation between microbial indicators data and pathogens loads, and identifies novel visualization approaches and conducts distribution analysis for microbial indicators and pathogens in a commercial poultry processing facility. From the data analyzed, a greater number of locations were statistically different between shifts under reduced levels of chemical interventions with higher means at the second shift for both indicators and pathogens levels. Minimal to negligible correlation was found when comparing aerobic counts and Enterobacteriaceae counts with Salmonella levels, with significant variability between sampling locations. Distribution analysis and visualization as a bio-map of the process resulted in a clear bimodality in reduced chemical conditions for multiple locations mostly explained by shift effect. The development and use of bio-mapping data, including proper data visualization, improves the tools needed for ongoing decision making in food safety systems.

- Abstract
Background: Evidence is accumulating that coronavirus disease 2019 increases the risk of hospitalization and mechanical ventilation in pregnant patients and for preterm delivery. However, the impact on maternal mortality and whether morbidity is differentially affected by disease severity at delivery and trimester of infection are unknown., Objective: This study aimed to describe disease severity and outcomes of severe acute respiratory syndrome coronavirus 2 infections in pregnancy across the Washington State, including pregnancy complications and outcomes, hospitalization, and case fatality., Study Design: Pregnant patients with a polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection between March 1, 2020, and June 30, 2020, were identified in a multicenter retrospective cohort study from 35 sites in Washington State. Sites captured 61% of annual state deliveries. Case-fatality rates in pregnancy were compared with coronavirus disease 2019 fatality rates in similarly aged adults in Washington State using rate ratios and rate differences. Maternal and neonatal outcomes were compared by trimester of infection and disease severity at the time of delivery., Results: The principal study findings were as follows: (1) among 240 pregnant patients in Washington State with severe acute respiratory syndrome coronavirus 2 infections, 1 in 11 developed severe or critical disease, 1 in 10 were hospitalized for coronavirus disease 2019, and 1 in 80 died; (2) the coronavirus disease 2019-associated hospitalization rate was 3.5-fold higher than in similarly aged adults in Washington State (10.0% vs 2.8%; rate ratio, 3.5; 95% confidence interval, 2.3-5.3); (3) pregnant patients hospitalized for a respiratory concern were more likely to have a comorbidity or underlying conditions including asthma, hypertension, type 2 diabetes mellitus, autoimmune disease, and class III obesity; (4) 3 maternal deaths (1.3%) were attributed to coronavirus disease 2019 for a maternal mortality rate of 1250 of 100,000 pregnancies (95% confidence interval, 257-3653); (5) the coronavirus disease 2019 case fatality in pregnancy was a significant 13.6-fold (95% confidence interval, 2.7-43.6) higher in pregnant patients than in similarly aged individuals in Washington State with an absolute difference in mortality rate of 1.2% (95% confidence interval, -0.3 to 2.6); and (6) preterm birth was significantly higher among women with severe or critical coronavirus disease 2019 at delivery than for women who had recovered from coronavirus disease 2019 (45.4% severe or critical coronavirus disease 2019 vs 5.2% mild coronavirus disease 2019; P<.001)., Conclusion: Coronavirus disease 2019 hospitalization and case-fatality rates in pregnant patients were significantly higher than in similarly aged adults in Washington State. These data indicate that pregnant patients are at risk of severe or critical disease and mortality compared to nonpregnant adults, and also at risk for preterm birth., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: During the early months of the coronavirus disease 2019 pandemic, risks associated with severe acute respiratory syndrome coronavirus 2 in pregnancy were uncertain. Pregnant patients can serve as a model for the success of clinical and public health responses during public health emergencies as they are typically in frequent contact with the medical system. Population-based estimates of severe acute respiratory syndrome coronavirus 2 infections in pregnancy are unknown because of incomplete ascertainment of pregnancy status or inclusion of only single centers or hospitalized cases. Whether pregnant women were protected by the public health response or through their interactions with obstetrical providers in the early months of pandemic is not clearly understood., Objective: This study aimed to estimate the severe acute respiratory syndrome coronavirus 2 infection rate in pregnancy and to examine the disparities by race and ethnicity and English language proficiency in Washington State., Study Design: Pregnant patients with a polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection diagnosed between March 1, 2020, and June 30, 2020 were identified within 35 hospitals and clinics, capturing 61% of annual deliveries in Washington State. Infection rates in pregnancy were estimated overall and by Washington State Accountable Community of Health region and cross-sectionally compared with severe acute respiratory syndrome coronavirus 2 infection rates in similarly aged adults in Washington State. Race and ethnicity and language used for medical care of pregnant patients were compared with recent data from Washington State., Results: A total of 240 pregnant patients with severe acute respiratory syndrome coronavirus 2 infections were identified during the study period with 70.7% from minority racial and ethnic groups. The principal findings in our study were as follows: (1) the severe acute respiratory syndrome coronavirus 2 infection rate was 13.9 per 1000 deliveries in pregnant patients (95% confidence interval, 8.3-23.2) compared with 7.3 per 1000 (95% confidence interval, 7.2-7.4) in adults aged 20 to 39 years in Washington State (rate ratio, 1.7; 95% confidence interval, 1.3-2.3); (2) the severe acute respiratory syndrome coronavirus 2 infection rate reduced to 11.3 per 1000 deliveries (95% confidence interval, 6.3-20.3) when excluding 45 cases of severe acute respiratory syndrome coronavirus disease 2 detected through asymptomatic screening (rate ratio, 1.3; 95% confidence interval, 0.96-1.9); (3) the proportion of pregnant patients in non-White racial and ethnic groups with severe acute respiratory syndrome coronavirus disease 2 infection was 2- to 4-fold higher than the race and ethnicity distribution of women in Washington State who delivered live births in 2018; and (4) the proportion of pregnant patients with severe acute respiratory syndrome coronavirus 2 infection receiving medical care in a non-English language was higher than estimates of pregnant patients receiving care with limited English proficiency in Washington State (30.4% vs 7.6%)., Conclusion: The severe acute respiratory syndrome coronavirus 2 infection rate in pregnant people was 70% higher than similarly aged adults in Washington State, which could not be completely explained by universal screening at delivery. Pregnant patients from nearly all racial and ethnic minority groups and patients receiving medical care in a non-English language were overrepresented. Pregnant women were not protected from severe acute respiratory syndrome coronavirus 2 infection in the early months of the pandemic. Moreover, the greatest burden of infections occurred in nearly all racial and ethnic minority groups. These data coupled with a broader recognition that pregnancy is a risk factor for severe illness and maternal mortality strongly suggested that pregnant people should be broadly prioritized for coronavirus disease 2019 vaccine allocation in the United States similar to some states., (Copyright © 2021 Elsevier Inc.

- Abstract
Primary central nervous system lymphoma has been traditionally described in patients with immunodeficiency syndromes; however, there is an increasing number of immunocompetent patients with this type of tumor that have been reported recently. In this paper we have retrospectively analyzed 22 immunocompetent patients with a confirmed diagnosis of primary lymphoma of the brain. The mean age in this group was 65 years with a similar male/female ratio. The time of evolution of the clinical course was 80.4 days and it was mainly characterized by headache and focal neurological deficit. In four patients multiple lesions were observed, while the remaining presented single lesions mainly located in the periventricular area of the cerebral hemispheres. All patients were initially administered steroids and a stereotactic biopsy was performed. The majority of tumors were histologically classified as diffuse large cells and all of them showed a positive reaction to B-cells antigens on immunohistochemistry. All patients were treated with radiotherapy and in 10 of them, chemotherapy with methotrexate was also indicated. The mean survival rate was II months among patients treated with radiotherapy alone and increased to 36 months when chemotherapy was added.

- Abstract
This is an observational retrospective study. Our goal is to describe the local dermonecrotic reaction occurring after a spider bite in eleven pediatric patients. In seven (63.7%), the spider was identified as Loxosceles reclusa, and in four, bites were presumptive. The main symptoms and signs were pain, erythema, swelling, blisters, and vasculitis in five patients. There was a significant relationship between the time of onset before the treatment and the severity of the lesions (63.4 hours in the severe cases vs 14.4 hours in the mild cases, p < 0.05), as well the time spent in the emergency room (50 hours vs 10 hours respectively, p < 0.05). Treatment with dapsone, 1 mg/kg/24 h, and/or paracetamol and dicloxacillin was successful; one case required surgical treatment. No systemic loxoscelism occurred in this patient.

- Abstract
Study Objective: To evaluate the efficacy of N-acetylcysteine (N-AC) alone or combined with multiple-dose activated charcoal (AC) in the treatment of acetaminophen (ACT) overdose., Design: Prospective observational case series of 14 consecutive pediatric patients. Group A (n = 7) were treated only with N-AC and group B (n = 7) with N-AC combined with AC. Plasma ACT concentrations were measured at 0.0, 24 and 48 h. As a measure of ACT disappearance, half-life of elimination (t1/2 beta) and exogenous body clearance (ClB) were calculated., Results: Group A, Initial and final mean ACT plasmatic levels were 27 micrograms/mL and 4 micrograms/mL; t1/2 beta of 17 h and ClB 0.640 mL.kg.min. Group B, 27 micrograms/mL and 0.66 microgram/mL; t1/2 beta of 10 h and ClB 1.092 mL.kg.min. For both t1/2 beta and ClB differences, p < 0.05 (SS)., Conclusion: N-AC significantly decreased the plasma ACT levels in both treatments; however, there were several advantages with the combined therapy: AC enhanced the efficacy of N-AC according with the higher eliminatión of the overdosed drug (97.6% vs. 85.2%), the t1/2 beta decreased 42%, and the ClB increased 70% in relation to the group A. Data of this study suggested that N-AC plus AC is more effective than N-AC alone in enhancing ACT elimination in overdosed patients and that it provided additional hepatoprotective benefit.
