Percentage Distribution

Objective: To investigate the association between the ABO blood group and the COVID-19 susceptibility. Material & Methods: The study is a retrospective cohort study. It included all hospitalized confirmed COVID-19 patients in Qatif central hospital, Eastern province, Saudi Arabia. Results: Our sample consists of 72 patients, we found a percentage distribution of 23.62%, 33.33%, 9.72%, and 33.33% for blood groups A, B, AB and O, respectively. Our results showed significantly increased risk for AB blood groups and significantly lower risk for the O blood group. Although there was a higher percentage distribution of the B blood group among COVID-19 patients as compared to the blood donors’ groups, this difference did not reach statistical significance. Conclusion: patients with AB blood group have higher susceptibility while patients with O blood group have lower susceptibility to COVID-19 infection. Our study has limitations and further studies are needed.

The Impact

Abstract Background: CA-UTI consider one of the most common hospital acquired infections. Several risk factors for CA-UTI have been identified. There is no enough evidence regard the impact of ABO type and the risk of CA-UTI acquisition. The aim of this study is to investigate the correlation between ABO types and the risk of having recurrent, reinfection CA-UTI, and MDR reinfection in critically ill.Methodology: A retrospective cohort study of adult ICU patients through 2018 in ICU at tertiary hospital who have confirmed CA-UTI to investigate the correlation between ABO type with the susceptibility of recurrent, reinfection and MDR reinfection CA-UTI in critically ill. 1730 patients were reviewed to screen patients for inclusion into the study,203 patients have confirmed CA-UTI using 2010 IDSA guideline definition.81patients meeting inclusion/exclusion criteria were enrolled. Patients were divided into two groups based on ABO type (O-group Vs. Non-O group). We considered a P value of < 0.05 as statistically significant.Results: Among 81 patients, 37 patients (45.6%) had O blood group type. Patients with O blood group type were associated with lower rate of recurrent CA-UTI (OR 0.28, 95% CI 0.085-0.952, P = 0.0414), multidrug resistant (MDR) organisms (OR 0.05, 95% CI 0.003-0.752, P = 0.0304), shorter ICU LOS (Est (SE): -0.024 (0.045), P = <0.001) and mechanical ventilation duration (Est. (SE): -0.41 (0.066), P = <0.001) compared with non-O blood group type. On the other hand, neither CA-UTI reinfection (OR 1.47, 95% CI 0.357-6.054, P = 0.5538) nor ICU mortality (OR 0.70, 95% CI 0.219-2.257, P = 0.5538) were statistically significant.Conclusion: Patients with non-O group type were statistically significant associated with higher rate of recurrent CA-UTI and MDRO. These data confirm the need for randomized controlled trials with a larger sample size to clarify and confirm our study findings.

The Relationship

ObjectiveTo examine the relationship between visit-to-visit systolic blood pressure (SBP) variability and patient-reported outcome measure of disability in multiple sclerosis (MS) patients.DesignA retrospective cohort study of individuals with MS who completed a patient-determined disease steps (PDDS) scale between 2011 and 2015 at an MS specialty clinic.ParticipantsIndividuals with MS for whom both a completed PDDS scale and ≥3 SBP measures within the prior 12 months of the survey were available.Main outcome measureParticipants were grouped into three classes of disability (no or mild (PDDS 0–1), moderate (2–3), severe (4–7)). SBP variability was calculated as within-subject SD using all SBP measures taken during the past 12 months. SBP variability was analysed by Tertile groups.ResultsNinety-two subjects were included in this analysis. Mean PDDS score was 2.22±1.89. Compared with subjects in Tertile 1 (lowest variability), the odds of being in a higher disability group was 3.5 times higher (OR=3.48; 95% CI: 1.08 to 11.25; p=0.037) in Tertile 2 and 5.2 times higher (OR=5.19; 95% CI: 1.53 to 17.61; p=0.008) in Tertile 3 (highest variability), independent of mean SBP, age, sex, race/ethnicity, body mass index and comorbidities (p for trend=0.008). Mean PDDS scores were 1.52±1.18 in Tertile 1, 2.73±1.02 in Tertile 2 and 2.42±0.89 in Tertile 3 after adjusting for the same covariates.ConclusionsOur results show a significant gradient relationship between SBP variability and MS-related disability. More research is needed to determine the underlying pathophysiological relationship between SBP variability and MS disability progression.
