Objective:: We aimed to evaluate the maternal outcomes among pregnant women with major degree placenta previa. Methods:: We conducted an observational cohort study on 80 pregnant women diagnosed with major placenta previa (grades III and IV where the placenta partially or completely cover the internal cervical os) after 20 weeks of pregnancy, within the period from January 2019 to June 2019. The diagnosis of placenta previa was made by ultrasound and confirmed at the time of delivery. The study participants were divided into three groups based on the placental location (Anterior, Central, and Posterior). All analyses were conducted using IBM SPSS software package version 20.0. Results:: Eighty pregnant women, with a mean age of 32.3 (5.01) years and a mean gestational age of 36.2 (2.03) weeks, were included in our study. Of them, 56.30% had a previous abortion, and previous Cs delivery was reported in 75%. Most of the placenta previa cases were central (52.5%), with a completely covered internal cervical os (70%). Thirty-nine patients (48.8%) had placenta accreta. Blood transfusion, postpartum hemorrhage, and anemia were noted with a percentage of 75%, 32.5%, and 32.5%, respectively. Around 28.8% of the included patients had a hysterectomy. Before and after delivery, nine patients (21.4%) and 15 patients (35.7%) of the placenta previa centralis group had anemia, respectively. Moreover, there was no statistically significant difference between the three studies groups in terms of anemia before and after delivery (P= 0.41 and P= 0.78. respectively). Placenta previa centralis showed a higher incidence of CS hysterectomy (45.2%) while wound infection was higher in anterior placenta previa (18.2%). Conclusion:: As a predictor of possible obstetric adverse events, placenta previa should be considered. A combination of proper clinical assessment and timely delivery to reduce the associated complications should be considered as well as developing a prenatal screening protocol.

Introduction Electrolytes disorders are common findings in kidney diseases and might represent a useful biomarker preceding kidney injury. Serum potassium [K+] imbalance is still poorly investigated for association with acute kidney injury (AKI) and most evidence come from intensive care units (ICU). The aim of our study was to comprehensively investigate this association in a large, unselected cohort of hospitalized patients. Methods: We performed a retrospective observational cohort study on the inpatient population admitted to Fondazione Policlinico Universitario A. Gemelli IRCCS between January 1, 2010 and December 31, 2014 with inclusion of adult patients with at least 2 [K+] and 3 serum creatinine (sCr) measurements who did not develop AKI during an initial 10-day window. The outcome of interest was in-hospital AKI. The exposures of interest were [K+] fluctuations and hypo (HoK) and hyperkalemia (HerK). [K+] variability was evaluated using the coefficient of variation (CV). Cox proportional hazards regression models were used to obtain hazard ratios (HRs) and 95% confidence intervals (CIs) of the association between the exposures of interest and development of AKI. Results: 21,830 hospital admissions from 18,836 patients were included in our study. During a median follow-up of 5 (interquartile range [IQR] 7) days, AKI was observed in 555 hospital admissions (2.9%); median time for AKI development was 5 (IQR 7) days. Higher [K+] variability was independently associated with increased risk of AKI with a statistically significant linear trend across groups (p-value = 0.012). A significantly higher incidence of AKI was documented in patients with HerK compared with normokalemia. No statistically significant difference was observed between HoK and HerK (p-value = 0.92). Conclusion: [K+] abnormalities including fluctuations even within the normal range are associated with development of AKI.

AbstractObjectiveTo determine the distribution, and specifically the true 99th centile, of high sensitivity cardiac troponin I (hs-cTnI) for a whole hospital population by applying the hs-cTnI assay currently used routinely at a large teaching hospital.DesignProspective, observational cohort study.SettingUniversity Hospital Southampton NHS Foundation Trust, Southampton, United Kingdom, between 29 June 2017 and 24 August 2017.Participants20 000 consecutive inpatients and outpatients undergoing blood tests for any clinical reason. Hs-cTnI concentrations were measured in all study participants and nested for analysis except when the supervising doctor had requested hs-cTnI for clinical reasons.Main outcome measuresDistribution of hs-cTnI concentrations of all study participants and specifically the 99th centile.ResultsThe 99th centile of hs-cTnI for the whole population was 296 ng/L compared with the manufacturer’s quoted level of 40 ng/L (currently used clinically as the upper limit of normal; ULN). Hs-cTnI concentrations were greater than 40 ng/L in one in 20 (5.4%, n=1080) of the total population. After excluding participants diagnosed as having acute myocardial infarction (n=122) and those in whom hs-cTnI was requested for clinical reasons (n=1707), the 99th centile was 189 ng/L for the remainder (n=18 171). The 99th centile was 563 ng/L for inpatients (n=4759) and 65 ng/L for outpatients (n=9280). Patients from the emergency department (n=3706) had a 99th centile of 215 ng/L, with 6.07% (n=225) greater than the recommended ULN. 39.02% (n=48) of all patients from the critical care units (n=123) and 14.16% (n=67) of all medical inpatients had an hs-cTnI concentration greater than the recommended ULN.ConclusionsOf 20 000 consecutive patients undergoing a blood test for any clinical reason at our hospital, one in 20 had an hs-cTnI greater than the recommended ULN. These data highlight the need for clinical staff to interpret hs-cTnI concentrations carefully, particularly when applying the recommended ULN to diagnose acute myocardial infarction, in order to avoid misdiagnosis in the absence of an appropriate clinical presentation.Trial registrationClinicaltrials.govNCT03047785.

Abstract Objectives To describe the prevalence and nature of bacterial co-infections in COVID-19 patients within 48 hours of hospital admission and assess the appropriateness of empirical antibiotic treatment they received. Methods In this retrospective observational cohort study, we included all adult non-pregnant patients who were admitted to two acute hospitals in North West London in March and April 2020 and confirmed to have COVID-19 infection within 2 days of admission. Results of microbiological specimens taken within 48 hours of admission were reviewed and their clinical significance was assessed. Empirical antibiotic treatment of representative patients was reviewed. Patient age, gender, co-morbidities, inflammatory markers at admission, admission to ICU and 30 day all-cause in-hospital mortality were collected and compared between patients with and without bacterial co-infections. Results Of the 1396 COVID-19 patients included, 37 patients (2.7%) had clinically important bacterial co-infection within 48 hours of admission. The majority of patients (36/37 in those with co-infection and 98/100 in selected patients without co-infection) received empirical antibiotic treatment. There was no significant difference in age, gender, pre-existing illnesses, ICU admission or 30 day all-cause mortality in those with and without bacterial co-infection. However, white cell count, neutrophil count and CRP on admission were significantly higher in patients with bacterial co-infections. Conclusions We found that bacterial co-infection was infrequent in hospitalized COVID-19 patients within 48 hours of admission. These results suggest that empirical antimicrobial treatment may not be necessary in all patients presenting with COVID-19 infection, although the decision could be guided by high inflammatory markers.

Abstract Aim This study aimed to identify the association between total visitation restriction because of the coronavirus 2019 (COVID-19) pandemic and the incidence of delirium for emergency inpatients. Methods This was a single-center, retrospective, observational cohort study conducted at a tertiary critical care center in urban Kyoto, Japan. Adult emergency patients hospitalized between January 1, 2019, and June 30, 2020, were recruited. In response to the COVID-19 pandemic, the authors’ hospital began restricted visitation on March 28, 2020. This study defined before visitation restriction as January 1, 2019, through March 31, 2020, and after visitation restriction as April 1, 2020, through June 30, 2020. We did not restrict emergency services, and there were no changes in the hospital’s routine, except for visitation restrictions. The primary outcome was the incidence of delirium. The adjusted odds ratio (AOR) with 95% confidence interval (CI) for delirium incidence was calculated to compare the before and after visitation restriction periods, and the logistic model was used to adjust for seven variables: age, sex, ward type on admission, primary diagnosis, ventilator management, general anesthesia surgery, and dementia. Results Study participants were 6264 patients, median age 74 years (56–83), and 3303 men (52.7%). The total delirium incidence in entire research period was 2.5% (158 of 6264 patients), comprising 1.8% (95/5251) before visitation restriction and 6.2% (63/1013) after visitation restriction. The AOR for delirium incidence was 3.79 (95% CI, 2.70–5.31) after visitation restriction versus before visitation restriction. Subgroup analysis showed no apparent interaction for delirium incidence. Conclusion Visitation restriction was associated with an increased incidence of delirium in emergency inpatients.

527 Background: A few reports have shown no difference between the efficacy of infusional FU and that of oral FU (Capecitabine/S-1) for colorectal cancer, and some studies have reported the non-inferiority between infusional FU/Oxaliplatin (OX) and oral FU/OX for metastatic colorectal cancer (mCRC). We performed a sub-group comparison between infusional FU/OX (mFOLFOX6 + BV: iFU) and oral FU/OX (CapeOX/SOX + BV: oFU) from the HGCSG0802 observational cohort study with investigated Japanese patients (pts) treated with first line BV for mCRC. Methods: The objective of HGCSG0802 was to evaluate progression-free survival (PFS), overall survival (OS), time to treatment-failure (TTF), response rate (RR), safety and so on. The key eligibility criteria of HGCSG0802 were with evaluable lesions, older than 20 years, ECOG PS 0-2, and this analysis used the cohort treated with OX-based regimens.In this analysis, pts characteristics, RR and safety were compared using Fisher’s exact test. PFS and TTF were compared using log-rank test. Results: Of 108 pts (the full analysis set), 95 pts were evaluable for treated with OX-based regimens. Forty-eight pts (50.5%) were treated with iFU and 47 pts (49.5%) were treated with oFU (CapeOX + BV 42 pts/SOX + BV 5 pts). The pts characteristics between those were generally balanced except for PS 0-1 (72.9% in iFU/93.6% in oFU; p=0.012) and synchronous liver metastases (mets) (93.8% in iFU/78.8% in oFU; p=0.040). Adverse events ≥grade 3 were balanced except for leucopenia (25.0% in iFU versus 2.1% in oFU; p=0.002) and neutropenia (43.5% in iFU and 10.9% in oFU; p=0.001). Hand-foot skin reaction was not different between two cohorts. RR was 62.5% in iFU versus 71.1% in oFU (p=0.835). The median PFS was 8.3 months in iFU versus 8.2 months in oFU (p=0.835). Conclusions: The HGCSG0802 could be a database to investigate first line BV for mCRC in clinical practice. As a result of this analysis, in Japanese daily practice, efficacy was no significant difference between infusional FU/OX and oral FU/OX, and the profiles of adverse events varied from each regimens.

Abstract Background: Hypothyroidism is the second most common endocrinological disease during pregnancy, with percentages that can range between 3.2 and 5.5%. A good maternal and foetal health outcome depends on thyroid hormone replacement therapy. The goal of such therapy is to maintain thyrotropin (TSH) in a range that is specific for pregnant women and varies between the trimesters of pregnancy. In our study, we wanted to analyse the adherence to hypothyroidism treatment among pregnant women and to evaluate the degree of control of the disease.Methods: We performed a retrospective observational cohort study in pregnant women between 2012 and 2018 in the Lleida health region. Therapeutic adherence was analysed by the proportion of days covered (PDC). The relationship with other variables was assessed using the regression coefficients and their 95% confidence interval (CI).Results: We examined a sample of 17281 women, representing more than 92% of the pregnant women in the Lleida health region in the period analysed. Among this sample, the mean prevalence of hypothyroidism was 6.52% (0.07% clinical and 6.45% subclinical). 3.3% of the 17281 pregnant women were treated. Among them, the mean adherence score was 79.6 ± 22.2. Of these, 54% presented high adherence. The latter had a higher mean age and better TSH control, in comparison to the ones showing low adherence. Conclusions: Half of the treated patients had good adherence to treatment and a better TSH control, in comparison to the others. Most of them achieved a good control at the third trimester of pregnancy.

Abstract Background SARS-CoV-2 is frequently shed in the stool of patients hospitalised with COVID-19. The extent of faecal shedding of SARS-CoV-2 among individuals in the community, and its potential to contribute to spread of disease, is unknown. Methods In this prospective, observational cohort study among households in Liverpool, UK, participants underwent weekly nasal/throat swabbing to detect SARS-CoV-2 virus, over a 12-week period from enrolment starting July 2020. Participants that tested positive for SARS-CoV-2 were asked to provide a stool sample three and 14 days later. In addition, in October and November 2020, during a period of high community transmission, stool sampling was undertaken to determine the prevalence of SARS-CoV-2 faecal shedding among all study participants. SARS-CoV-2 RNA was detected using Real-Time PCR. Results A total of 434 participants from 176 households were enrolled. Eighteen participants (4.2%: 95% confidence interval [CI] 2.5–6.5%) tested positive for SARS-CoV-2 virus on nasal/throat swabs and of these, 3/17 (18%: 95% CI 4–43%) had SARS-CoV-2 detected in stool. Two of three participants demonstrated ongoing faecal shedding of SARS-CoV-2, without gastrointestinal symptoms, after testing negative for SARS-CoV-2 in respiratory samples. Among 165/434 participants without SARS-CoV-2 infection and who took part in the prevalence study, none had SARS-CoV-2 in stool. There was no demonstrable household transmission of SARS-CoV-2 among households containing a participant with faecal shedding. Conclusions Faecal shedding of SARS-CoV-2 occurred among community participants with confirmed SARS-CoV-2 infection. However, during a period of high community transmission, faecal shedding of SARS-CoV-2 was not detected among participants without SARS-CoV-2 infection. It is unlikely that the faecal-oral route plays a significant role in household and community transmission of SARS-CoV-2.
