Changes in emergency department utilisation in Germany before and during different phases of the COVID-19 pandemic, using data from a national surveillance system up to June 2021.

BACKGROUND: During the COVID-19 pandemic and associated public health and social measures, decreasing patient numbers have been described in various healthcare settings in Germany, including emergency care. This could be explained by changes in disease burden, e.g. due to contact restrictions, but could also be a result of changes in utilisation behaviour of the population. To better understand those dynamics, we analysed routine data from emergency departments to quantify changes in consultation numbers, age distribution, disease acuity and day and hour of the day during different phases of the COVID-19 pandemic. METHODS: We used interrupted time series analyses to estimate relative changes for consultation numbers of 20 emergency departments spread throughout Germany. For the pandemic period (16-03-2020 - 13-06-2021) four different phases of the COVID-19 pandemic were defined as interruption points, the pre-pandemic period (06-03-2017 - 09-03-2020) was used as the reference. RESULTS: The most pronounced decreases were visible in the first and second wave of the pandemic, with changes of - 30.0% (95%CI: - 32.2%; - 27.7%) and - 25.7% (95%CI: - 27.4%; - 23.9%) for overall consultations, respectively. The decrease was even stronger for the age group of 0-19 years, with - 39.4% in the first and - 35.0% in the second wave. Regarding acuity levels, consultations assessed as urgent, standard, and non-urgent showed the largest decrease, while the most severe cases showed the smallest decrease. CONCLUSIONS: The number of emergency department consultations decreased rapidly during the COVID-19 pandemic, without extensive variation in the distribution of patient characteristics. Smallest changes were observed for the most severe consultations and older age groups, which is especially reassuring regarding concerns of possible long-term complications due to patients avoiding urgent emergency care during the pandemic.

Propionate attenuates atherosclerosis by immune-dependent regulation of intestinal cholesterol metabolism.

AIMS: Atherosclerotic cardiovascular disease (ACVD) is a major cause of mortality and morbidity worldwide, and increased low-density lipoproteins (LDLs) play a critical role in development and progression of atherosclerosis. Here, we examined for the first time gut immunomodulatory effects of the microbiota-derived metabolite propionic acid (PA) on intestinal cholesterol metabolism. METHODS AND RESULTS: Using both human and animal model studies, we demonstrate that treatment with PA reduces blood total and LDL cholesterol levels. In apolipoprotein E-/- (Apoe-/-) mice fed a high-fat diet (HFD), PA reduced intestinal cholesterol absorption and aortic atherosclerotic lesion area. Further, PA increased regulatory T-cell numbers and interleukin (IL)-10 levels in the intestinal microenvironment, which in turn suppressed the expression of Niemann-Pick C1-like 1 (Npc1l1), a major intestinal cholesterol transporter. Blockade of IL-10 receptor signalling attenuated the PA-related reduction in total and LDL cholesterol and augmented atherosclerotic lesion severity in the HFD-fed Apoe-/- mice. To translate these preclinical findings to humans, we conducted a randomized, double-blinded, placebo-controlled human study (clinical trial no. NCT03590496). Oral supplementation with 500 mg of PA twice daily over the course of 8 weeks significantly reduced LDL [-15.9 mg/dL (-8.1%) vs. -1.6 mg/dL (-0.5%), P = 0.016], total [-19.6 mg/dL (-7.3%) vs. -5.3 mg/dL (-1.7%), P = 0.014] and non-high-density lipoprotein cholesterol levels [PA vs. placebo: -18.9 mg/dL (-9.1%) vs. -0.6 mg/dL (-0.5%), P = 0.002] in subjects with elevated baseline LDL cholesterol levels. CONCLUSION: Our findings reveal a novel immune-mediated pathway linking the gut microbiota-derived metabolite PA with intestinal Npc1l1 expression and cholesterol homeostasis. The results highlight the gut immune system as a potential therapeutic target to control dyslipidaemia that may introduce a new avenue for prevention of ACVDs.

Tumor load rather than contrast enhancement is associated with the visual function of children and adolescents with optic pathway glioma - a retrospective Magnetic Resonance Imaging study.

INTRODUCTION: Optic pathway gliomas are often asymptomatic tumors occurring in children with neurofibromatosis type 1 (NF1 + OPG) or sporadically (spOPG). Treatment is usually prompted by visual loss and/or tumor progression on MRI. The aim of this study was to investigate the relationship between visual acuity (VA), tumor growth, and contrast enhancement to provide more distinct indications for the administration of gadolinium-based contrast agents. METHODS: Tumor load was retrospectively measured and enhancement semi-quantitatively scored on 298 MRIs of 35 patients (63% NF1 + OPG). Spearman rank correlation between tumor load and enhancement was calculated and a linear mixed model used to examine the influence of tumor load and enhancement on corresponding VA tests (LogMAR). RESULTS: The optic nerve width in NF1 + OPGs was strongly associated with VA (regression coefficient 0.75; confidence interval 0.61-0.88), but weakly with enhancement (0.06; -0.04-0.15). In spOPGs, tumor volume and optic nerve width were more relevant (0.31; -0.19-0.81 and 0.39; 0.05-0.73) than enhancement (0.09; -0.09-0.27). CONCLUSIONS: Tumor load measures may be more relevant for the surveillance of optic pathway gliomas than enhancement, given that VA is the relevant outcome parameter. Regular contrast administration should therefore be questioned in these patients.

High prevalence of multidrug-resistant Gram-negative bacteria carriage in children screened prospectively for multidrug resistant organisms at admission to a paediatric hospital, Hamburg, Germany, September 2018 to May 2019.

BackgroundIncreasing resistance to antibiotics poses medical challenges worldwide. Prospective data on carriage prevalence of multidrug resistant organisms (MDRO) in children at hospital admission are limited and associated risk factors are poorly defined.AimTo determine prevalence of MDRO carriage in children at admission to our paediatric hospital in Hamburg and to identify MDRO carriage risk factors.MethodsWe prospectively obtained and cultured nasal/throat and inguinal/anal swabs from children (≤ 18 years) at admission between September 2018 and May 2019 to determine prevalence of meticillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Gram-negative bacteria (MRGN) and vancomycin-resistant enterococcus (VRE) and associated species. We collected medical histories using a questionnaire and evaluated 31 risk factors using logistic regression models.ResultsMDRO carriage prevalence of 3,964 children was 4.31% (95% confidence interval (CI): 3.69-5.00). MRSA carriage prevalence was 0.68% (95% CI: 0.44-0.99), MRGN prevalence was 3.64% (95% CI: 3.07-4.28) and VRE prevalence 0.08% (95% CI: 0.02-0.22). MDRO carriage was associated with MRGN history (odds ratio (OR): 6.53; 95% CI: 2.58-16.13), chronic condition requiring permanent care (OR: 2.67; 95% CI: 1.07-6.13), antibiotic therapy (OR: 1.92, 95% CI: 1.24-2.94), living in a care facility (OR: 3.34; 95% CI: 0.72-12.44) and refugee status in previous 12 months (OR: 1.91; 95% CI: 0.27-8.02). Compared to established practice, screening using risk-factors had better diagnostic sensitivity (86.13%; 95% CI: 80.89-91.40) and specificity (73.54%; 95% CI: 72.12-74.97).ConclusionMRGN carriage was higher than MRSA and VRE. Extended risk-factor-based admission screening system seems warranted.

Histologic and Clinical Effects of Different Topical Corticosteroids for Eosinophilic Esophagitis: Lessons from an Updated Meta-Analysis of Placebo-Controlled Randomized Trials.

BACKGROUND: Topical corticosteroids (TS) have become standard therapy for eosinophilic esophagitis (EoE). However, a variety of drug formulations have been used for which results of histological and clinical responses may be different. We aimed at determining the short-term histologic efficacy of TS for EoE based on randomized placebo-controlled trials and to review clinical response. METHODS: We searched MEDLINE, ISI Web of Science, and clinicaltrials.gov for randomized controlled trials (RCTs) on TS versus placebo for active EoE published until June 2019. Treatment effects were calculated as risk ratios (RRs) comparing histologic remission between groups. RESULTS: Nine RCTs (6 budesonide and 3 fluticasone) involving a total of 483 participants were included. A substantial overall effect of TS on acute histologic remission (RR 12.5, 95% confidence interval 6.0-25.9) was found despite varying definitions of histologic response. Indirect comparisons between drug and formulation types showed a trend for a better histologic efficacy of budesonide (RR 13.5 vs. 10.4 fluticasone) and for the orodispersible tablet (RR 46.2 vs. 11.5 suspension, and 10.4 nebulized formula/spray), but only based on small patient numbers. Scores used for clinical response assessment were different between studies, and short-term clinical results were less impressive: significant differences favoring TS were found in 4/9 RCTs (4/6 budesonide, 0/3 fluticasone). CONCLUSIONS: TS are effective for short-term induction of histological remission in EoE with less impressive clinical response rates. The mode of drug delivery to the esophagus may be a relevant factor for the degree of histologic remission. Further trials should use uniform assessment criteria and long-term patient-centered outcomes.

Methods to estimate proportion and number of nonexposed cases in a population.

National mortality statistics commonly provide disease-specific absolute and relative frequencies of death by sex and age, but not by exposure status. However, it is often of interest to know how many of the diseased individuals, that is the cases, were exposed or not exposed to a specific risk factor. We present two methods to estimate the proportion and the number of exposed and nonexposed cases, both of which require an estimate of the exposure prevalence in the nondiseased population. Method I additionally requires an estimate of the relative effect of exposure, that is a relative risk function if the exposure has a continuous distribution, or a relative risk estimate for each category if the exposure is categorical. Method II additionally requires an estimate of the disease rate among the nonexposed. We provide theoretical justifications, discuss practical limitations, and provide an R script to calculate the probability for nonexposure among the diseased, and compare the approaches. Both methods are subsequently applied to the estimation of the number of never smokers among lung cancer deaths. The two suggested methods rely on the availability of specific data sources and might therefore be applicable in different research settings. Both methods yield unbiased estimates of the number of nonexposed cases, given that the respective underlying assumptions are fulfilled.

Association of a Multigenetic Pro-Inflammatory Profile with Ischaemic Stroke.

OBJECTIVE: A multigenetic pro-inflammatory profile may increase stroke risk. We investigated whether a higher number of pro-inflammatory genetic variants are associated with ischaemic stroke risk and whether other risk factors further elevate this risk. METHODS: In a case-control study with 470 ischaemic stroke patients (cases) and 807 population controls, we investigated 23 haplotypes or alleles in 16 inflammatory genes (interleukin [IL]1A, IL1B, IL1 receptor antagonist, IL6, IL6 receptor, IL10, tumour necrosis factor-a; C-C motif chemokine ligand 2, C-C motif chemokine receptor 5, C-reactive protein (CRP), intercellular adhesion molecule 1, transforming growth factor ß1, E-Selectin, selenoprotein S, cluster determinant 14, histone deacetylase 9 [HDAC9]). We constructed an extended gene score (EGS) as the sum of all individual risk alleles and analysed its effect on stroke, just as its association and interaction with cardiovascular risk factors and infectious scores (IgG antibodies against 5 respectively IgA antibodies against 4 microbial antigens). RESULTS: Cases were less likely to carry the minor allele of IL10 rs1800872 and more likely to carry the HDAC9 allele rs11984041 and the pro-inflammatory haplotype of CRP, although the latter was not statistically significant in our study. Overall, cases tended to have more pro-inflammatory alleles and haplotypes than controls (mean ± SD 13.25 ± 2.25 and 13.04 ± 2.41, respectively). However, the EGS only slightly and not significantly increased the risk of stroke (OR 1.04, 95% CI 0.99-1.09). Its effect was neither associated with included risk factors nor with IgA and IgG infectious scores, and we found no significant interaction effects. CONCLUSION: A more pro-inflammatory genetic profile might increase stroke risk to some extent. This potential effect is most likely independent of established cardiovascular risk factors and the infectious burden of an individual.

Secondary tethered cord syndrome in adult patients: retethering rates, long-term clinical outcome, and the effect of intraoperative neuromonitoring.

BACKGROUND: The strategy for surgical treatment of tethered cord syndrome in pediatric patients is well established but still bares challenges for adult patients. This retrospective study was performed to assess the surgical outcome of adult patients with a secondary tethered cord syndrome and to evaluate the benefit of intraoperative neuromonitoring. METHODS: Clinical charts of 32 consecutive adult patients who underwent in total 38 surgical untethering procedures at our facility between 2008 and 2018 were retrospectively analyzed. Epidemiological data, MRI scans, and postoperative results were evaluated. RESULTS: The retethering rate in our patient cohort was 16%. Main complaints were maximal pain (82%), bladder dysfunction (79%), paresthesia (68%), and weakness in the lower extremities (68%). Forty-eight months after surgery, patients' symptoms generally improved, with an average level of pain of 19.1% (95% CI, 5.7-32.5%), paresthesia 28.7% (95% CI, 12.6-44.8%), weakness in the lower extremities 27.7% (95% CI, 11.1-44.4%), and bladder dysfunction 60.2% (95% CI, 41.6-78.7%). The use of neuromonitoring appears to have a positive impact on patient weakness (OR = 0.07; 95% CI, 0.01-0.68) and paresthesia (OR = 0.03; 95% CI, 0.00-2.18). This benefit is less clear for the retethering rate (OR = 0.45; 95% CI, 0.06-3.26) or the overall clinical outcome (OR = 0.70; 95% CI, 0.14-3.45). The presence of a preoperative Chiari syndrome, syringomyelia, or scoliosis had no relevant influence on the retethering rate. CONCLUSIONS: Our data confirms that untethering surgery in adult patients is relatively safe and has a reasonable chance of clinical improvement of pain, paresthesia, and weakness in the lower extremities. The use of intraoperative monitoring has a positive influence on the improvement of preoperative paralysis.

Population-based study of autoimmune hepatitis and primary biliary cholangitis in Germany: rising prevalences based on ICD codes, yet deficits in medical treatment.

BACKGROUND: Population-based data on the prevalence of and real-life treatment for the autoimmune liver diseases (AILD), primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH), are scarce, and such knowledge may help to improve patient care. METHODS: Data of 8.1 million individuals having health insurance with the "Techniker Krankenkasse," the largest German health insurer, were analyzed with regard to the prevalence of and prescribed medication for AILD in Germany from 2011 until 2014. Patients with viral hepatitis B infection (HBV) and alcoholic liver cirrhosis (ALC) served as control groups. Case definition was based on ICD codes. RESULTS: The prevalences of PBC and AIH were 36.9/100 000 inhabitants (95 % CI: 35.6-38.2) and 23.0/100 000 inhabitants (95 % CI: 22.0-24.0) in 2014, respectively. The prevalences of AILD increased from 2011 to 2014 (for PBC by 31 % and for AIH by 29 %), with the largest increase for male patients with PBC. In contrast, the prevalence of HBV declined while that of ALC remained stable. The analysis of prescribed real-life treatment revealed considerable deviations from standard treatment recommendations. Specifically, in older patients with PBC or AIH, undertreatment was common. CONCLUSION: The prevalence of PBC and AIH based on ICD codes is increasing in Germany. The analysis of real-life treatment in this large and population-based cohort points to the unmet need to improve the implementation of treatment guidelines for autoimmune liver diseases in the broader medical community.

Applicability of two violence risk assessment tools in a psychiatric prison hospital population.

The risk of violent behavior is known to be higher for patients who suffer from a severe mental disorder. However, specific prediction tools for clinical work in prison psychiatry are lacking. In this single-center study, two violence risk assessment tools (Forensic Psychiatry and Violence Tool, "FoVOx," and Mental Illness and Violence Tool, "OxMIV") were applied to a prison hospital population with a primary psychotic or bipolar disorder and subsequently compared. The required information on all items of both tools was obtained retrospectively for a total of 339 patients by evaluation of available patient files. We obtained the median and inter-quartile range for both FoVOx and OxMIV, and their rank correlation coefficient along with 95% confidence intervals (CIs)-for the full cohort, as well as for cohort subgroups. The two risk assessment tools were strongly positively correlated (Spearman correlation = 0.83; 95% CI = 0.80-0.86). Such a high correlation was independent of nationality, country of origin, type of detention, schizophrenia-spectrum disorder, previous violent crime and alcohol use disorder, where correlations were above 0.8. A lower correlation was seen with patients who were 30 years old or more, married, with affective disorder and with self-harm behavior, and also in patients without aggressive behavior and without drug use disorder. Both risk assessment tools are applicable as an adjunct to clinical decision making in prison psychiatry.

Quantitative Lesion Water Uptake in Acute Stroke Computed Tomography Is a Predictor of Malignant Infarction.

Background and Purpose- Early selection of patients with acute middle cerebral artery infarction at risk for malignant edema is critical to initiate timely decompressive surgery. Net water uptake (NWU) per brain volume is a quantitative imaging biomarker of space-occupying ischemic edema which can be measured in computed tomography. We hypothesize that NWU in early infarct lesions can predict development of malignant edema. The aim was to compare NWU in acute brain infarct against other common predictors of malignant edema. Methods- After consecutive screening of single-center registry data, 153 patients with acute proximal middle cerebral artery occlusion fulfilled the inclusion criteria. A total of 29 (18.2%) patients developed malignant edema defined as end point in follow-up imaging leading to decompressive surgery and death as a direct implication of mass effect. Early infarct lesion volume and NWU were quantified in multimodal admission computed tomography; time from symptom onset to admission imaging was recorded. Results- Mean time from onset to admission imaging was equivalent between patients with and without malignant infarcts (mean±SD: 3.3±1.4 hours and 3.3±1.7 hours, respectively). Edematous tissue expansion by NWU within infarct lesions occurred across all patients in this cohort (NWU: 9.1%±6.8%; median, 7.9%; interquartile range, 8.8%; range, 0.1%-35.6%); 7.0% (±5.2) in nonmalignant and 18.0% (±5.7) in malignant infarcts. Based on univariate receiver operating characteristic curve analysis, NWU >12.7% or an edema rate >3.7% NWU/h identified malignant infarcts with high discriminative power (area under curve, 0.93±0.02). In multivariate binary logistic regression, the probability of malignant infarct was significantly associated with early infarct volume and NWU. Conclusions- Computed tomography-based quantitative NWU in early infarct lesions is an important surrogate marker for developing malignant edema. Besides volume of early infarct, the measurements of lesion water uptake may further support identifying patients at risk for malignant infarction.

Impulsivity predicts illness severity in long-term course of bipolar disorder: A prospective approach.

BACKGROUND: Bipolar disorder is a common, severe and chronic mental illness. Despite this, predictors of illness severity remain poorly understood. Impulsivity is reported to be associated with bipolar disorder and aggravating comorbidities. This study therefore sought to examine the predictive value of impulsivity for determining illness severity in euthymic bipolar disorder patients. METHODS: Baseline trait impulsivity of 120 bipolar euthymic patients (81 bipolar disorder I [68%], 80 female [67%]) and 51 healthy controls was assessed using Barratt Impulsiveness Scale 11. The impact of impulsivity on illness severity (measured with morbidity index) was prospectively tested in 97 patients with sufficient follow-up data (average observation time: 54.4 weeks), using linear regression analysis. RESULTS: Barratt Impulsiveness Scale 11 total (ß = 0.01; p < 0.01) and in particular Barratt Impulsiveness Scale 11 attentional subscale scores (ß = 0.04; p < 0.001) predicted illness severity in bipolar disorder, while controlling for other clinical variables. Only age at onset persisted as an additional, but less influential predictor. Barratt Impulsiveness Scale 11 total scores and Barratt Impulsiveness Scale 11 attentional subscale scores were significantly higher in euthymic patients compared to controls. This was not observed for the motor or non-planning subscale scores. LIMITATIONS: The average year-long observation time might not be long enough to account for the chronic course of bipolar disorder. CONCLUSION: Trait impulsivity and particularly attentional impulsivity in euthymic bipolar patients can be strong predictors of illness severity in bipolar disorder. Future studies should explore impulsivity as a risk assessment for morbidity and as a therapeutic target in bipolar disorder patients.

Contribution of Established Stroke Risk Factors to the Burden of Stroke in Young Adults.

BACKGROUND AND PURPOSE: As stroke in young adults is assumed to have different etiologies and risk factors than in older populations, the aim of this study was to examine the contribution of established potentially modifiable cardiovascular risk factors to the burden of stroke in young adults. METHODS: A German nationwide case-control study based on patients enrolled in the SIFAP1 study (Stroke In Young Fabry Patients) 2007 to 2010 and controls from the population-based GEDA study (German Health Update) 2009 to 2010 was performed. Cases were 2125 consecutive patients aged 18 to 55 years with acute first-ever stroke from 26 clinical stroke centers; controls (age- and sex-matched, n=8500, without previous stroke) were from a nationwide community sample. Adjusted population-attributable risks of 8 risk factors (hypertension, hyperlipidemia, diabetes mellitus, coronary heart disease, smoking, heavy episodic alcohol consumption, low physical activity, and obesity) and their combinations for all stroke, ischemic stroke, and primary intracerebral hemorrhage were calculated. RESULTS: Low physical activity and hypertension were the most important risk factors, accounting for 59.7% (95% confidence interval, 56.3-63.2) and 27.1% (95% confidence interval, 23.6-30.6) of all strokes, respectively. All 8 risk factors combined explained 78.9% (95% confidence interval, 76.3-81.4) of all strokes. Population-attributable risks of all risk factors were similar for all ischemic stroke subtypes. Population-attributable risks of most risk factors were higher in older age groups and in men. CONCLUSIONS: Modifiable risk factors previously established in older populations also account for a large part of stroke in younger adults, with 4 risk factors explaining almost 80% of stroke risk.

Association of Computed Tomography Ischemic Lesion Location With Functional Outcome in Acute Large Vessel Occlusion Ischemic Stroke.

BACKGROUND AND PURPOSE: Ischemic lesion volume (ILV) assessed by follow-up noncontrast computed tomography correlates only moderately with clinical end points, such as the modified Rankin Scale (mRS). We hypothesized that the association between follow-up noncontrast computed tomography ILV and outcome as assessed with mRS 3 months after stroke is strengthened when taking the mRS relevance of the infarct location into account. METHODS: An anatomic atlas with 66 areas was registered to the follow-up noncontrast computed tomographic images of 254 patients from the MR CLEAN trial (Multicenter Randomized Clinical Trial of Endovascular Treatment of Acute Ischemic Stroke in the Netherlands). The anatomic brain areas were divided into brain areas of high, moderate, and low mRS relevance as reported in the literature. Based on this distinction, the ILV in brain areas of high, moderate, and low mRS relevance was assessed for each patient. Binary and ordinal logistic regression analyses with and without adjustment for known confounders were performed to assess the association between the ILVs of different mRS relevance and outcome. RESULTS: The odds for a worse outcome (higher mRS) were markedly higher given an increase of ILV in brain areas of high mRS relevance (odds ratio, 1.42; 95% confidence interval, 1.31-1.55 per 10 mL) compared with an increase in total ILV (odds ratios, 1.16; 95% confidence interval, 1.12-1.19 per 10 mL). Regression models using ILV in brain areas of high mRS relevance instead of total ILV showed a higher quality. CONCLUSIONS: The association between follow-up noncontrast computed tomography ILV and outcome as assessed with mRS 3 months after stroke is strengthened by accounting for the mRS relevance of the affected brain areas. Future prediction models should account for the ILV in brain areas of high mRS relevance.

Socioeconomic Conditions in Childhood, Adolescence, and Adulthood and the Risk of Ischemic Stroke.

BACKGROUND AND PURPOSE: The association between socioeconomic status in adulthood and the risk of stroke is well established; however, the independent effects of socioeconomic conditions in different life phases are less understood. METHODS: Within a population-based stroke registry, we performed a case-control study with 470 ischemic stroke patients (cases) aged 18 to 80 years and 809 age- and sex-matched stroke-free controls, randomly selected from the population (study period October 2007 to April 2012). We assessed socioeconomic conditions in childhood, adolescence, and adulthood, and developed a socioeconomic risk score for each life period. RESULTS: Socioeconomic conditions were less favorable in cases regarding paternal profession, living conditions and estimated family income in childhood, school degree, and vocational training in adolescence, last profession, marital status and periods of unemployment in adulthood. Using tertiles of score values, low socioeconomic conditions during childhood (odds ratio 1.77; 95% confidence interval 1.20-2.60) and adulthood (odds ratio 1.74; 95% confidence interval 1.16-2.60) but not significantly during adolescence (odds ratio 1.64; 95% confidence interval 0.97-2.78) were associated with stroke risk after adjustment for risk factors and other life stages. Medical risk factors attenuated the effect of childhood conditions, and lifestyle factors reduced the effect of socioeconomic conditions in adolescence and adulthood. Unfavorable childhood socioeconomic conditions were particularly associated with large artery atherosclerotic stroke in adulthood (odds ratio 2.13; 95% confidence interval 1.24-3.67). CONCLUSIONS: This study supports the hypothesis that unfavorable childhood socioeconomic conditions are related to ischemic stroke risk, independent of established risk factors and socioeconomic status in adulthood, and fosters the idea that stroke prevention needs to begin early in life.

All-Suture Anchor vs. Knotless Suture Anchor for the Treatment of Anterior Shoulder Instability-A Prospective Cohort Study.

All-suture or soft-anchors (SA) represent a new generation of suture anchor technology with a completely suture-based system. This study's objective was to assess Juggerknot® SA, for arthroscopic Bankart repair in recurrent shoulder instability (RSI), and to compare it to a commonly performed knotless anchor (KA) technique (Pushlock®). In a prospective cohort study, 30 consecutive patients scheduled for reconstruction of the capsulolabral complex without substantial glenoid bone loss were included and operated on using the SA technique. A historical control group was operated on using the KA technique for the same indication. Clinical examinations were performed preoperatively and 12 and 24 months postoperatively. RSI and WOSI at 24 months were the co-primary endpoints, evaluated with logistic and linear regression. A total of 5 out of 30 (16.7%) patients suffered from RSI in the SA group, one out of 31 (3.2%) in the KA group (adjusted odds ratio = 10.12, 95% CI: 0.89-115.35), and 13.3% in the SA group and 3.2% in the KAgroup had a revision. The median WOSI in the SA group was lower than in the KA group (81% vs. 95%) (adjusted regression coefficient = 10.12, 95% CI: 0.89-115.35). Arthroscopic capsulolabral repair for RSI using either the SA or KA technique led to satisfying clinical outcomes. However, there is a tendency for higher RSI and lower WOSI following the SA technique.

The sFlt-1/PlGF-ratio and the risk of preeclampsia-related adverse outcomes in subsequent pregnancies with signs and symptoms of a preeclampsia.

OBJECTIVES: This study characterizes the outcome of two subsequent pregnancies with suspected preeclampsia (PE). We investigated the diagnostic accuracy of clinical signs, Doppler examinations, and the soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF)-ratio to predict PE-related adverse outcomes (AO). The sFlt-1/PlGF-ratio of the first pregnancy was compared to the outcome of the subsequent pregnancy. STUDY DESIGN: A total of 1928 patients at risk for preeclampsia were screened, of them 1117 were eligible for inclusion. Of these, 84 women presented with suspected PE in two subsequent pregnancies. OUTCOME MEASURES: Diagnostic accuracy of clinical markers was assessed. Associations between the sFlt-1/PlGF-ratio in the first and the odds of an AO in the subsequent pregnancy were investigated with logistic regression. RESULTS: The prevalence of AOs decreased from 27.4 % in the first to 17.9 % in the second pregnancy. Comparison of the accuracy of the different clinical markers for an AO showed a high specificity for an sFlt-1/PlGF-ratio at the cut-off of ≥ 85 in both pregnancies (81.3 %, 95 % CI 63.6-92.8 vs 92.6 %,95 % CI 83.7-97.6), but a lower sensitivity in the second pregnancy (92.9 %, 95 % CI 66.1-99.8 vs 33.3%, 95 % CI 11.8-61.6). An elevated sFlt-1/PlGF-ratio in the first did not increase the odds of an AO in the subsequent pregnancy. CONCLUSIONS: The prevalence of AOs decreases in subsequent pregnancies. Our finding that the sFlt-1/PlGF-ratio of the first was not related to the outcome of the subsequent pregnancy suggests that angiogenic markers are only a within-pregnancy short-term tool to assess AOs.

Identifying patients at risk for myasthenic crisis with hemogram and inflammation-related laboratory parameters - a pilot study.

Background: Myasthenia gravis (MG) is a rare autoimmune disease characterized by fatigable weakness of the voluntary muscles and can exacerbate to life-threatening myasthenic crisis (MC), requiring intensive care treatment. Routine laboratory parameters are a cost-effective and widely available method for estimating the clinical outcomes of several diseases, but so far, such parameters have not been established to detect disease progression in MG. Methods: We conducted a retrospective analysis of selected laboratory parameters related to inflammation and hemogram for MG patients with MC compared to MG patients without MC. To identify potential risk factors for MC, we applied time-varying Cox regression for time to MC and, as a sensitivity analysis, generalized estimating equations logistic regression for the occurrence of MC at the next patient visit. Results: 15 of the 58 examined MG patients suffered at least one MC. There was no notable difference in the occurrence of MC by antibody status or sex. Both regression models showed that higher counts of basophils (per 0.01 unit increase: HR = 1.32, 95% CI = 1.02-1.70), neutrophils (per 1 unit increase: HR = 1.40, 95% CI = 1.14-1.72), potentially leukocytes (per 1 unit increase: HR = 1.15, 95% CI = 0.99-1.34), and platelets (per 100 units increase: HR = 1.54, 95% CI = 0.99-2.38) may indicate increased risk for a myasthenic crisis. Conclusion: This pilot study provides proof of the concept that increased counts of basophils, neutrophils, leukocytes, and platelets may be associated with a higher risk of developing MC in patients with MG.

SARS-CoV-2 Test-to-Stay in Daycare.

BACKGROUND AND OBJECTIVES: Test-to-stay concepts apply serial testing of children in daycare after exposure to SARS-CoV-2 without use of quarantine. This study aims to assess the safety of a test-to-stay screening in daycare facilities. METHODS: 714 daycare facilities and approximately 50 000 children ≤6 years in Cologne, Germany participated in a SARS-CoV-2 Pool-polymerase chain reaction (PCR) screening from March 2021 to April 2022. The screening initially comprised post-exposure quarantine and was adapted to a test-to-stay approach during its course. To assess safety of the test-to-stay approach, we explored potential changes in frequencies of infections among children after the adaptation to the test-to-stay approach by applying regression discontinuity in time (RDiT) analyses. To this end, PCR-test data were linked with routinely collected data on reported infections in children and analyzed using ordinary least squares regressions. RESULTS: 219 885 Pool-PCRs and 352 305 Single-PCRs were performed. 6440 (2.93%) Pool-PCRs tested positive, and 17 208 infections in children were reported. We estimated that during a period of 30 weeks, the test-to-stay concept avoided between 7 and 20 days of quarantine per eligible daycare child. RDiT revealed a 26% reduction (Exp. Coef: 0.74, confidence interval 0.52-1.06) in infection frequency among children and indicated no significant increase attributable to the test-to-stay approach. This result was not sensitive to adjustments for 7-day incidence, season, SARS-CoV-2 variant, and socioeconomic status. CONCLUSIONS: Our analyses provide evidence that suggest safety of the test-to-stay approach compared with quarantine measures. This approach offers a promising option to avoid use of quarantine after exposure to respiratory pathogens in daycare settings.
