Comparison of the clinical characteristics, glycemic control, and pregnancy outcomes between women with gestational diabetes mellitus in waves I and III of the COVID-19 pandemic: a reference center report.

OBJECTIVES: The medical care of patients with gestational diabetes mellitus (GDM) during the COVID-19 pandemic was influenced by changing epidemiological conditions and government regulations. Aim - To compare the clinical pregnancy data of GDM women between waves I and III of the pandemic. MATERIAL AND METHODS: We performed a retrospective analysis of medical records from the GDM clinic and compared the periods of March-May 2020 (wave I) and March-May 2021 (wave III). RESULTS: Women with GDM during wave I (n = 119) compared to wave III (n = 116) were older (33.0 ± 4.7 vs 32.1 ± 4.8 years; p = 0.07), booked later (21.8 ± 8.4 vs 20.3 ± 8.5 weeks; p = 0.17), and had their last appointment earlier (35.5 ± 2.0 vs 35.7 ± 3.2 weeks; p < 0.01). Telemedicine consultations were used more frequently during wave I (46.8% vs 24.1%; p < 0.01), while insulin therapy was used less often (64.7% vs 80.2%; p < 0.01). Mean fasting self-measured glucose did not differ (4.8 ± 0.3 vs 4.8 ± 0.3 mmol/L; p = 0.49), but higher postprandial glucose was reported during wave I (6.6 ± 0.9 vs 6.3 ± 0.6 mmol/l; p < 0.01). Pregnancy outcome data were available for 77 wave I pregnancies and 75 wave III pregnancies. The groups were similar in terms of gestational week of delivery (38.3 ± 1.4 vs 38.1 ± 1.6 weeks), cesarean sections (58.4% vs 61.3%), APGAR scores (9.7 ± 1.0 vs 9.7 ± 1.0 pts), and birth weights (3306.6 ± 457.6 g vs 3243.9 ± 496.8 g) (p = NS for all). The mean wave I neonate length was slightly higher (54.3 ± 2.6 cm vs 53.3 ± 2.6 cm; p = 0.04). CONCLUSIONS: We identified differences between wave I and wave III pregnancies for several clinical characteristics. However, nearly all pregnancy outcomes were found to be similar.

Case Report of Cerebral Sinus Thrombosis Related to Immune Thrombotic Thrombocytopenia Following Administration of ChAdOx1 nCoV-19 for Vaccination against COVID-19.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) with cerebral venous sinus thrombosis (CVST) has been recently reported after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a patient with fulminant CVST and thrombocytopenia after receiving the ChAdOx1 nCoV-19 vaccine. Although the patient received immediate anticoagulant and intravenous immune globulin treatment, he died within 24 h after hospital admission. VITT and CVST are rare conditions; however, the course may be fatal. Therefore, clinicians should be familiarized with the clinical and laboratory features of VITT.

Clinical course and outcome of SARS-CoV-2 infection in multiple sclerosis patients treated with disease-modifying therapies - the Polish experience.

INTRODUCTION: The aim of this study was to report the course and outcome of SARS-CoV-2 infection in multiple sclerosis (MS) patients treated with disease-modifying therapies (DMTs) in Poland. A major concern for neurologists worldwide is the course and outcome of SARS-CoV-2 infection in patients with MS treated with different DMTs. Although initial studies do not suggest an unfavourable course of infection in this group of patients, the data is limited. MATERIALS AND METHODS: This study included 396 MS patients treated with DMTs and confirmed SARS-CoV-2 infection from 28 Polish MS centres. Information concerning patient demographics, comorbidities, clinical course of MS, current DMT use, as well as symptoms of SARS-CoV-2 infection, need for pharmacotherapy, oxygen therapy, and/or hospitalisation, and short-term outcomes was collected up to 30 January 2021. Additional data about COVID-19 cases in the general population in Poland was obtained from official reports of the Polish Ministry of Health. RESULTS: There were 114 males (28.8%) and 282 females (71.2%). The median age was 39 years (IQR 13). The great majority of patients with MS exhibited relapsing-remitting course (372 patients; 93.9%). The median EDSS was 2 (SD 1.38), and the mean disease duration was 8.95 (IQR 8) years. Most of the MS patients were treated with dimethyl fumarate (164; 41.41%). Other DMTs were less frequently used: interferon beta (82; 20.70%), glatiramer acetate (42; 10.60%), natalizumab (35;8.84%), teriflunomide (25; 6.31%), ocrelizumab (20; 5.05%), fingolimod (16; 4.04), cladribine (5; 1.26%), mitoxantrone (3; 0.76%), ozanimod (3; 0.76%), and alemtuzumab (1; 0.25%). The overall hospitalisation rate due to COVID-19 in the cohort was 6.81% (27 patients). Only one patient (0.3%) died due to SARS-CoV-2 infection, and three (0.76%) patients were treated with mechanical ventilation; 106 (26.8%) patients had at least one comorbid condition. There were no significant differences in the severity of SARS-CoV-2 infection regarding patient age, duration of the disease, degree of disability (EDSS), lymphocyte count, or type of DMT used. CONCLUSIONS AND CLINICAL IMPLICATIONS: Most MS patients included in this study had a favourable course of SARS-CoV-2 infection. The hospitalisation rate and the mortality rate were not higher in the MS cohort compared to the general Polish population. Continued multicentre data collection is needed to increase the understanding of SARS-CoV-2 infection impact on the course of MS in patients treated with DMTs.

Effect of COVID-19 pandemic on stroke admissions and quality of stroke interventional treatment in Masovian Voivodeship.

AIM OF STUDY: To assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on the pathway of stroke interventional services and major quality indicators of stroke reperfusion therapies in Masovian Voivodeship. MATERIALS AND METHODS: An exploratory retrospective analysis was performed at two comprehensive stroke centres to assess changes in stroke care between the early phase of the COVID-19 pandemic (weeks 10-18 of 2020) and the same period in 2019. RESULTS: Of the 419 included stroke patients, 186 (44.4%) presented during the COVID-19 period. There was an increase in in-hospital delays for reperfusion therapies, and a significant decrease in the number of acute cerebrovascular accident admissions, predominantly related to a low number of transient ischaemic attack (TIA) admissions to hospital (-20.17%). The delays were shorter in the mothership paradigm than in the drip-and-ship paradigm of acute stroke care (onset-to-groin 293 vs. 232 min, p = 0.03). No differences in stroke aetiology, large-vessel occlusion frequency, or severe stroke admissions in the COVID-19 period were observed. CONCLUSIONS AND CLINICAL IMPLICATIONS: COVID-19's emergence was correlated with a significant reduction in admissions to stroke departments, particularly for TIAs, and a prolonged delay in reperfusion stroke treatment, especially in the drip-and-ship paradigm. An educational campaign to raise public awareness of TIA and/or stroke symptoms and immediate reorganisation of stroke care during the COVID-19 era are necessary.
