RESUMO
BACKGROUND: Post-dural puncture headache (PDPH) is a frequent complication following lumbar puncture, epidural analgesia, or neuraxial anesthesia. The International Classification of Headache Disorders, third edition categorizes PDPH as a self-limiting condition; however, emerging evidence, including our findings, suggests that PDPH can have a prolonged course, challenging this traditional view. OBJECTIVES: To elucidate the diagnostic characteristics and treatment outcomes of persistent PDPH (pPDPH), offering insights into its demographic profiles and diagnostic features. METHODS: We executed an anonymous, web-based survey targeting individuals aged ≥18 years diagnosed with or suspected of having pPDPH. Recruitment occurred through self-help groups on Facebook. The survey comprised questions regarding diagnostic procedures, treatment regimens, outcomes, and healthcare consultation. RESULTS: The survey achieved a response rate of 179/347 (51.6%) individuals completing the questionnaire. Cerebrospinal fluid (CSF) leaks were confirmed in nine of 179 (5.0%) cases. Signs of intracranial hypotension without a CSF leak were observed in 70/179 (39.1%) individuals. All participants underwent magnetic resonance imaging scans of the brain and spine, with computed tomography myelography performed in 113/179 (63.1%) cases. Medications, including analgesics, theophylline, and gabapentin, provided minimal short-term relief. Epidural blood patch treatments resulted in slight-to-moderate short-term improvement in 136/179 (76.0%), significant improvement in 22/179 (12.3%), and complete effectiveness in eight of 179 (4.5%) individuals. For long-term outcomes, slight-to-moderate improvement was reported by 118/179 (66.0%) individuals. Surgical interventions were carried out in 42/179 (23.5%) patients, revealing pseudomeningoceles intraoperatively in 20/42 (47.6%) individuals. After surgery, 21/42 (50.0%) of the participants experienced slight-to-moderate improvement, 12/42 (28.6%) showed more pronounced improvement, and five of the 42 (11.9%) achieved complete effectiveness. CONCLUSION: This study underscores the complexities of managing pPDPH. The delay in diagnosis can impact the effectiveness of treatments, including epidural blood patch and surgical interventions, resulting in ongoing symptoms. This underscores the importance of tailored and adaptable treatment strategies. The findings advocate for additional research to deepen the understanding of pPDPH and improve long-term patient outcomes.

BACKGROUND AND OBJECTIVES: Postdural puncture headache (PDPH) is an acknowledged consequence of procedures like lumbar punctures, epidural analgesia, and neurosurgical interventions. Persistence over more than three months, however has been poorly studied. In particular, little is known about the impact of persistent PDPH (pPDPH) on health related quality of life (HRQoL), disability and ability to work. The study aimed to provide a holistic understanding of pPDPH, encompassing medical, physical and psychological aspects. METHODS: We conducted a cross-sectional anonymous online survey in individuals aged 18 or older, diagnosed with, or suspected to have pPDPH via self-help groups on Facebook. Participants completed a structured questionnaire covering diagnosis, symptoms, and the ability to work. For assessing headache related disability, and mental health, they filled in the Henry Ford Hospital Headache Disability Inventory (HDI) and the Depression Anxiety Stress Scale-21 (DASS-21). RESULTS: A total of 179 participants (83.2% female, mean age 39.7 years) completed the survey. PPDPH had been present for one year or more in 74.3%, and 44.1% were unable to be in an upright position for more than one hour per day without having to lie down or sit down. Headaches were extremely severe or severe in 18% and 34%, respectively. According to the HDI, 31.8% of participants had mild, 25.7% moderate, and 42.5% severe disability. DASS-21 revealed substantial mental health challenges with depression, anxiety and stress experienced by 83%, 98%, and 88% of the respondents. The ability to work was limited considerably: 27.9% were unable to work, 59.8% worked part-time, 1.1% changed their job because of pPDPH, and only 11.2% were able to work full-time in their previous job. Despite treatment, the patients' condition had deteriorated in 32.4% and remained unchanged in 27.9%. CONCLUSION: This study stresses the burden of pPDPH in terms of substantial disability, limited quality of life, mental health concerns, and significant impact on the ability to work. The study highlights the long-term impact of pPDPH on individuals, emphasizing the need for timely diagnosis and effective treatment. It underscores the complexity of managing pPDPH and calls for further research into its long-term effects on patient health and HRQoL.

INTRODUCTION: Neonatal sepsis accounts for 0.97% of all disability-adjusted life years worldwide. Interleukin-6 has been used in sepsis diagnosis, but cut-off values are missing. METHODS: Neonates admitted to the neonatal wards with measurements of serum interleukin-6 born between September 2015 and September 2019 were retrospectively analysed. Mean serum interleukin-6 values of patients who never had increased laboratory parameters of infection nor died during their stay and mean interleukin-6 values on the day of blood sampling for a later positive culture in patients with culture-confirmed sepsis were analysed for each time period. RESULTS: In all, 8.488 values in 1.695 neonates, including 752 very-preterm-infants and 701 very-low-birthweight infants, were analysed. The AUC for interleukin-6 was 0.84-0.91 in all neonates, 0.88-0.89 in very-preterm and 0.89-0.91 in very-low-birthweight infants. Using interleukin-6 cut-off values of 80 pg/ml on day of life 1, 40 pg/ml on day of life 2-7 and 30 pg/ml after day of life 7, a sensitivity of 75% and a specificity of 81% for culture-confirmed sepsis were achieved. In very-preterm infants, the corresponding values were 74% for sensitivity and 83% for specificity and in very-low-birthweight infants 74% and 86%, respectively. CONCLUSION: Serum interleukin-6 has high accuracy for the detection of neonatal sepsis. IMPACT: Serum interleukin-6 can be used with high accuracy to detect sepsis in neonates with the cut-off values of 80 pg/ml on day of life 1, 40 pg/ml on day of life 2-7 and 30 pg/ml after day of life 7. Serum interleukin-6 can be used with high accuracy to detect sepsis in neonates and very-preterm as well as very-low-birthweight infants. Interleukin-6 values display distinct cut-off values depending on the chronological age of the infant. Our article provides the first cut-off values for interleukin-6 in the first days of life in neonates.

Growth patterns and final body height are influenced by genetic and socio-environmental factors. A major impact of education on growth has been documented. Body height increases with an increasing educational level.The present study focuses on the association patterns between body height and educational level among 1,734,569 Austrian male conscripts aged 17 to <19 born between 1961 and 2002. Four levels of education were classified to examine their association with body height. Over 42 years, the percentage of conscripts at the lowest educational level decreased dramatically from 37.5% to 1.7%. All educational classes showed increasing body heights over time. Despite a marked improvement in the living standard, body heights at different educational levels did not converge. In Austria, educational and social advancement was associated with higher population body heights. Young men at the lowest educational level, however, remain shorter and their body height gap to the highest educational level has widened.

BACKGROUND: The prevalence of major depressive disorder (MDD) in women is up to 50% higher as compared to men. However, little is known about discrepancies in health care utilization between depressed female and male patients. Consequently, the aim of the present study was to elucidate gender differences regarding the frequency of hospital admissions and the length of inpatient treatment for MDD across the lifespan. METHODS: This nationwide, registry-based study analyzed all inpatient admissions in psychiatric hospitals due to recurrent/non-recurrent MDD episodes according to ICD-10 (moderate (F32/33.1), severe (F32/33.2), severe with psychotic features (F32/33.3)) in Austria across 14 years. We calculated weekly admission rates per 100,000 patients by directly age-standardized rates. RESULTS: Across 232,289 admissions (63.2% female) the population based admission rates in MDD were significantly higher in women (p < 0.001). Female to male ratios across subgroups were 1.65 (F32/33.1), 1.58 (F32/33.2), 1.73 (F32/33.3), and peaked around 65 years (ratio ≥ 2 for all subgroups). Length of hospital stay for women was significantly longer in all depression subtypes (p < 0.001). CONCLUSIONS: Elevated rates of inpatient treatment in women cannot solely be explained by a higher MDD prevalence and are dependent on age and type of depressive episode. Irrespective of the type and severity of the mood episode, women exhibit longer hospitalisation times.

BackgroundPostnatally, the immature left ventricle (LV) is subjected to high systemic afterload. Hypothesizing that LV pumping would change during transition-adaptation, we analyzed the LV in preterm infants (GA≤32+6), clinically stable or with a hemodynamically significant patent ductus arteriosus (hPDA) by applying a pump model.MethodsPumping was characterized by EA (effective arterial elastance, reflecting afterload), EES (end-systolic LV elastance, reflecting contractility), EA/EES coupling ratios, descriptive EA:EES relations, and EA/EES graphs. Data calculated from echocardiography and blood pressure were analyzed by diagnosis (S group: clinically stable, no hPDA, n=122; hPDA group, n=53) and by periods (early transition: days of life 1-3; late transition: 4-7; and adaptation: 8-30).ResultsS group: LV pumping was characterized by an increased EA/EES coupling ratio of 0.65 secondary to low EES in early transition, a tandem rise of both EA and EES in late transition, and an EA/EES coupling ratio of 0.45 secondary to high EES in adaptation; hPDA group: time-trend analyses showed significantly lower EA (P<0.0001) and EES (P=0.006). Therefore, LV pumping was characterized by a lower EA/EES coupling ratio (P=0.088) throughout transition-adaptation.ConclusionsIn stable infants, facing high afterload, the immature LV, enhanced by the physiological PDA, increases its contractility. In hPDA, facing low afterload, the overloaded immature LV exhibits a consistently lower contractility.

AIM: We evaluated the incidence of arterial catheterisation and analysed the risk factors and the extent and outcome of ischaemic complications in neonates. METHODS: This was a retrospective cohort study of 1506 neonates admitted to two, ten-bed neonatal intensive care units (NICUs) at the Medical University of Vienna, Austria, between 1 January 2011 and 31 December 2014. Medical charts, daily reports and photo documentation were reviewed for arterial catheterisation and ischaemic complications. Patients with severe ischaemic complications were followed up to evaluate extremity function, scaring and cosmetic results. RESULTS: There were 542 arterial catheterisations in 485 patients, including 275 born below 28 weeks, which resulted in severe complications in 19 of 485 (4%) patients. Three died before follow-up. Patients with complications had a significantly lower birthweight, lower postmenstrual age and higher rates of intracranial haemorrhage, retinopathy of prematurity and necrotising enterocolitis. They had also undergone multiple arterial catheterisations more often, needed longer inotropic support and had longer NICU stays than patients without complications. Extremity function was unimpaired in ten of 16 patients with severe ischaemic complications. CONCLUSION: Severe ischaemic complications in neonates following arterial catheterisation were rare events, but could cause devastating damage. Most patients didn't show impaired extremity function at follow-up.

OBJECTIVE: The benefit of carotid surgery in asymptomatic patients with high-grade internal carotid artery stenosis (ICAS) is subject of intense debate, and thus improved preoperative risk stratification is mandatory. This study aimed to investigate the predictive value of contralateral ICAS (cl-ICAS) for the preoperative clinical presentation of patients with ipsilateral ICAS (primary outcome). METHODS: This study was a post hoc analysis of a prospective cohort comprising 485 consecutive patients undergoing carotid endarterectomy for high-grade ICAS. Patients were classified by their clinical presentation, ie, asymptomatic (n = 213) or symptomatic (within 6 months of surgery; n = 272, comprising both transient ischemic attack [TIA; n = 163] and stroke [n = 109]). We investigated the association of cl-ICAS with the primary outcome in adjusted regression models. RESULTS: Mean ipsilateral degrees of ICAS were similar in both groups (84% ± 10% vs 84% ± 11%; P = .92), whereas contralateral degrees were significantly higher in the symptomatic group (29% ± 34% vs 38% ± 39%; P = .008). After multivariable regression analysis, cl-ICAS >60% conferred a three times higher preoperative stroke risk (odds ratio, 3.31; 95% confidence interval, 1.98-5.54; P < .001). Inclusion of cl-ICAS significantly improved (P = .001) ipsilateral combined TIA and stroke risk prediction based on established risk factors (area under the curve, 0.66; 95% confidence interval, 0.60-0.72; P < .001). CONCLUSIONS: Our study identifies a high contralateral degree of ICAS as an independent predictor of preoperative ipsilateral TIA and stroke in patients with ipsilateral high-grade ICAS. Therefore, such patients might rather benefit from elective carotid surgery and intensive postoperative medical care.

BACKGROUND & AIMS: The epidemiology of biliary tract cancers (BTC) varies between geographical regions and has changed over time globally. We investigated the incidence and mortality trends of patients diagnosed with BTC over a 20-year period in Austria. METHODS: Patients diagnosed with intrahepatic (iCCC)/extrahepatic cholangiocarcinoma (eCCC), ampullary carcinoma, gall bladder carcinoma (GBC), overlapping lesions or unspecified carcinomas of the biliary tract and liver were included. Data on age-adjusted incidence were obtained from the Austrian National Cancer Registry which compiles data on all newly diagnosed cancers. Data on age-adjusted mortality were obtained from the national death registry (Statistics Austria). RESULTS: Between 1990 and 2009, 15201 patients were diagnosed with BTC (m/f=42/58%; mean age, 73 years). The median survival of all patients with BTC was 4.8 months with a 1-/5-year survival rate of 31%/10%. In iCCC, the incidence and mortality rates increased from 1990 to 2009 in both men and women while in eCCC, the incidence and mortality rates decreased over time in both sexes. In ampullary carcinoma, the incidence slightly decreased in men and remained stable in women. The mortality rate remained stable in both sexes. In GBC, the age-adjusted incidence and mortality rates dramatically decreased in both sexes. CONCLUSIONS: GBC and iCCC were the most common entities amongst BTC. While incidence and mortality rates of iCCC increased in men and women over time, incidence and mortality rates of eCCC and GBC decreased in both sexes. Other carcinomas of the biliary tract i.e. ampullary carcinoma were rarely diagnosed.

The human growth process is influenced not only by genetic factors but also by environmental factors. Therefore, regional differences in mean body heights may exist within a population or a state. In the present study, we described and evaluated the regional trends in mean body heights in the nine Austrian provinces over a period spanning more than four decades. Body height data of 1734569 male conscripts born in Austria with Austrian citizenship between 1961 and 2002 were anonymized and analyzed. From 1961 to 2002 birth cohorts, an overall increase in the mean body height of Austrian recruits was observed, although regional differences were evident. Regions with shorter body heights in the 1961-1963 birth cohorts showed a particularly pronounced increase in mean body heights. Meanwhile, the course of body height growth in the capital city, Vienna, was striking, where the highest body heights were documented for the 1961-1963 birth cohorts. In Vienna, mean body heights continued to decline until the 1984 birth cohort and increased again from the 1988 birth cohorts. In addition to economic factors, increased stress factors in an urban environment and a form of urban penalty are discussed as causes.

BACKGROUND AND PURPOSE: A limited life expectancy reduces the benefit from carotid endarterectomy (CEA) for treatment of asymptomatic internal carotid artery stenosis. The aim of this study was to assess homocysteine as stratifying biomarker to improve prediction of postoperative survival. METHODS: This was a prospective, nonrandomized case series from 2003 to 2012. Two hundred and fourteen consecutive patients (<75 years, n=130; ≥75 years, n=84) undergoing CEA for their asymptomatic internal carotid artery stenosis were observed for 8.5 years for the occurrence of death after CEA as primary end point (EC-nr: 04-067-0604). Homocysteine and major cardiovascular risk factors were used for computation of prognostic indices. Cumulative survival of prognostic indices-based quintiles was estimated by Kaplan-Meier curves. RESULTS: Total homocysteine had a significant effect on postoperative survival (P<0.0001). Total homocysteine-based quintiles of prognostic indices showed a better prediction of the survival of the patients than age alone. This caused reclassification of 17 patients (20.2%)>75 years as fit for surgery, but also indicated a high risk for 19 patients (14.6%)<75 years. In the majority (79.8%) of patients aged>75 years, statistically, CEA could not be advised because of a significantly reduced 5-year survival rate. CONCLUSIONS: High plasma homocysteine levels suggest that older patients with asymptomatic carotid stenosis might rather benefit from intensive medical therapy than from CEA.

AIM: To investigate gender-related differences in amplitude-integrated electroencephalography (aEEG) associated with neurodevelopmental outcome at 3 years. METHODS: Preterms born <30 weeks' gestational age between 2000 and 2002 were prospectively included. aEEGs obtained within the first 2 weeks of life were classified according to aEEG composite scores - including background pattern, sleep-wake cycling (SWC) and seizure activity. Neurodevelopmental outcome was assessed at 3 years of age. RESULTS: Neurodevelopmental outcome data was available for 148 of 264 eligible infants - 64 showed a normal outcome and 84 an impaired outcome. A logistic regression model revealed a significant independent influence of IVH, analgetic/sedative/anticonvulsant medication, gestational age and gender on aEEG composite scores. Odds ratios for having an abnormal aEEG composite score within the first 2 weeks of life for 'female sex', 'no IVH', 'no medication' and 'gestational age' were calculated. aEEG did not differ between males and females with normal outcomes. In patients with abnormal outcome, however, male preterms showed more burst-suppression patterns and less SWC when compared with female preterms. CONCLUSION: Being male with an abnormal outcome at 3 years of age is reflected by a less mature early aEEG when compared with the one of females. This association is independent of IVH and medication and was less evident with increasing gestational age.

In the context of evaluating physical function in individuals with stroke, the 3-Meter Backward Walk Test (3MBWT) emerges as a potential tool of interest. The purpose of this study was to assess the test-retest reliability and concurrent validity of the 3MBWT and its correlation with falling incidents. Conducted in a neurological rehabilitation center, 35 ambulatory individuals with stroke were enrolled within a month post-stroke onset. These participants, with a Functional Ambulation Category score of ≥4, underwent the 3MBWT, Functional Gait Assessment (FGA), 10-Meter Walk Test (10MWT), and 6-Minute Walk Test (6MWT) under the supervision of different physiotherapists. The results indicate that the 3MBWT demonstrated high reliability, with an Intraclass Correlation Coefficient of 0.97 (95% CI: 0.95, 0.98). It also showed significant concurrent validity with other established walking tests like the 6MWT (r = -0.78) and 10MWT (r = 0.71), with a moderate correlation with the FGA (r = -0.54). No marked differences in test outcomes were observed between participants based on their fall history. Conclusively, the 3MBWT proves to be highly reliable and agrees well with existing walking function assessments for stroke patients, suggesting its potential as a time-efficient alternative.
RESUMO
BACKGROUND: Coercive measures such as involuntary psychiatric admission are considered a last resort in the treatment of people with psychiatric disorders. So far, numerous factors have been identified that influence their use. However, the link between a pandemic - in particular, restrictions such as lockdowns - and the use of involuntary psychiatric admission is unclear. AIM: To examine the association between COVID-19 lockdowns and involuntary psychiatric admissions in Austria. METHOD: This retrospective exploratory study assessed all involuntary psychiatric admissions and use of mechanical restraint in Austria, except for the federal state of Vorarlberg, between 1 January 2018 and 31 December 2020. Descriptive statistics and regression models were used. RESULTS: During the 3-year study period, 40 012 individuals (45.9% females, mean age 51.3 years) had 66 124 involuntary psychiatric admissions for an average of 10.9 days. Mechanical restraint was used during 33.9% of these admissions. In weeks of nationwide COVID-19 lockdowns (2020 v. 2018/2019), involuntary psychiatric admissions were significantly fewer (odds ratio = 0.93, P = 0.0001) but longer (11.6 (s.d.: 16) v. 10.9 (s.d.: 15.8) days). The likelihood of involuntary admission during lockdowns was associated with year (2020 v. 2018-2019; adjusted odds ratio = 0.92; P = 0.0002) but not with sex (P = 0.814), age (P = 0.310), use of mechanical restraint (P = 0.653) or type of ward (P = 0.843). CONCLUSIONS: Restrictions such as lockdowns affect coercive measures and resulted in fewer but longer involuntary psychiatric admissions during weeks of lockdown in Austria. These results strengthen previous findings that showed the dependence of coercive measures on external factors, highlighting the need to further clarify causality and desired prevention effects when using coercive measures.
RESUMO
Data from human and animal studies are highly suggestive of an influence of time of day of vaccine administration on host immune responses. In this population-based study, we aimed to investigate the effect of time of day of administration of a COVID-19 vector vaccine, ChAdOx1 nCoV-19 (AstraZeneca), on SARS-CoV-2 anti-spike S1 immunoglobulin (IgG) levels. Participants were 803 university employees who received their first vaccine dose in March 2021, had serology data at baseline and at 3 weeks, and were seronegative at baseline. Antibody levels were determined in binding antibody units (BAU/mL) using enzyme-linked immunosorbent assay (ELISA). Generalized additive models (GAM) and linear regression were used to evaluate the association of time of day of vaccination continuously and in hourly bins with antibody levels at 3 weeks. Participants had a mean age of 42 years (SD: 12; range: 21-74) and 60% were female. Time of day of vaccination was associated non-linearly ("reverse J-shape") with antibody levels. Morning vaccination was associated with the highest (9:00-10:00 h: mean 292.1 BAU/mL; SD: 262.1), early afternoon vaccination with the lowest (12:00-13:00 h: mean 217.3 BAU/mL; SD: 153.6), and late afternoon vaccination with intermediate (14:00-15:00 h: mean 280.7 BAU/mL; SD: 262.4) antibody levels. Antibody levels induced by 12:00-13:00 h vaccination (but not other time intervals) were significantly lower compared to 9:00-10:00 h vaccination after adjusting for potential confounders (beta coefficient = -75.8, 95% confidence interval [CI] = -131.3, -20.4). Our findings show that time of day of vaccination against SARS-CoV-2 has an impact on the magnitude of IgG antibody levels at 3 weeks. Whether this difference persists after booster vaccine doses and whether it influences the level of protection against COVID-19 needs further evaluation.

Mortality of cardiovascular diseases in patients with type 1 diabetes is increased 2- to 20-fold compared to non-diabetic individuals. In young adults with type 1 diabetes, cardiovascular events are more often the cause of premature death than nephropathy. The aim of this study was to evaluate the prevalence and extent of cardiovascular risk factors in children and adolescents with type 1 diabetes in Austria. In a cross sectional study data of children with type 1 diabetes <18 years of age treated at the Children's department of the University Hospitals of Vienna and Graz were collected. We recorded body mass index, waist circumference, blood pressure, HbA1c, triglycerides, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol according to age, sex, age at manifestation, diabetes duration, and insulin requirement. From 264 patients (49.4% male) complete data were available. Of all patients, 76.1% had one or more risk factors, 20.8% had two or more, 10.2% had three or more, and 4.9% had four or more risk factors. Insufficient glycemic control was the most frequent risk factor, present in 60.6% of our patients, followed by elevated triglycerides (22.7%) and increased body mass index (20.1%). Higher prevalence of risk factors was correlated with increasing age, diabetes duration, HbA1c, and insulin requirement. In conclusion, children and adolescents with type 1 diabetes have a much higher prevalence of cardiovascular risk factors compared to non-diabetic individuals. To prevent future cardiovascular events, achieving the best possible glycemic control, early detection of further risk factors, and adequate intervention are highly important.

BACKGROUND: Aside from the concept of seasonal affective disorder, the evidence for a seasonal pattern (SP) of major depressive disorder (MDD) is controversial. Furthermore, the effect of sex and age is still unclear. METHODS: This is a nationwide, registry-based study assessing all inpatient admissions in mental health hospitals due to MDD episodes according to ICD-10 (moderate (F32/33.1), severe (F32/33.2) and severe with psychotic features (F32/33.3)) in Austria across 14 years. Calculations were based on deviations from expected monthly admissions. RESULTS: The sample comprised 231,824 hospitalisations (36.8% men) for MDD. A significant SP (p=0.001) in moderate and severe depressive episodes in both women and men with decreased admission rates in the summer months and December was detected. In psychotic depression a significant SP was only evidenced in women (p = 0.002, men: p = 0.291). Patients older than 55 years had a reduced SP compared to those being younger. LIMITATIONS: Only anonymised admission data of inpatient treatments were available. Hospitalization rates cannot fully be equated to the occurrence of MDD. CONCLUSIONS: The current study indicates a seasonal variation in MDD symptoms that may go beyond seasonal affective disorder. Knowledge about the predictability of depressive symptoms in patients should encourage preventive strategies.

OBJECTIVE: We analyzed the annual prevalence of onset-DKA (diabetic ketoacidosis) from 2012 to 2020 with a sub-analysis for lockdown-periods during the COVID-19 pandemic in 2020. DESIGN: All newly diagnosed children with type 1 diabetes (T1D) aged <15 years are prospectively registered in the population-based Austrian Diabetes Incidence Study in Austria. MAIN OUTCOME MEASURES: The annual DKA prevalence was analyzed using Joinpoint regression. Definition of DKA: pH <7.3, mild DKA: pH 7.3 to ≤ 7.1, severe DKA: pH <7.1. DKA prevalence during the lockdown periods in 2020 and the corresponding periods in 2015-2019 were examined using Fisher's exact test. RESULTS: In the years 2012-2020 the mean prevalence for onset-DKA in Austria was 43.6% [95%CI (confidence interval): 41.6, 45.7] and thus above the mean prevalence of previous decades (1989-2011) of 37,1 % (95%CI: 35.6, 38.6). A particularly high prevalence was found among children <2 years of age (72.0% DKA, 32.8% severe DKA). No significant gender difference was found. Prevalence of severe DKA at T1D-onset increased significantly since 2015 (p = 0.023). During the lockdown in 2020, 59.3% of children were diagnosed with DKA at T1D-onset, compared to 42.1% during the previous 5 years (p = 0.022). Moreover, 20% of children had severe DKA at T1D diagnosis, compared to 14% during the comparison period. CONCLUSIONS: The previously already high prevalence of DKA at T1D-onset has further increased over time. The COVID-19 pandemic has exacerbated the problem of a late or delayed diagnosis of diabetes in children resulting in onset-DKA. The alarmingly increased prevalence of DKA in Austrian children with T1D calls for urgent action.
RESUMO
Transforming growth factor-beta cooperates with oncogenic Ras to activate nuclear beta-catenin during the epithelial to mesenchymal transition of hepatocytes, a process relevant in the progression of hepatocellular carcinoma (HCC). In this study we investigated the role of beta-catenin in the differentiation of murine, oncogene-targeted hepatocytes and in 133 human HCC patients scheduled for orthotopic liver transplantation. Transforming growth factor-beta caused dissociation of plasma membrane E-cadherin/beta-catenin complexes and accumulation of nuclear beta-catenin in Ras-transformed, but otherwise normal hepatocytes in p19(ARF)-/- mice. Both processes were inhibited by Smad7-mediated disruption of transforming growth factor-beta signaling. Overexpression of constitutively active beta-catenin resulted in high levels of CK19 and M2-PK, whereas ablation of beta-catenin by axin overexpression caused strong expression of CK8 and CK18. Therefore, nuclear beta-catenin resulted in dedifferentiation of neoplastic hepatocytes to immature progenitor cells, whereas loss of nuclear beta-catenin led to a differentiated HCC phenotype. Poorly differentiated human HCC showed cytoplasmic redistribution or even loss of E-cadherin, suggesting epithelial to mesenchymal transition. Analysis of 133 HCC patient samples revealed that 58.6% of human HCC exhibited strong nuclear beta-catenin accumulation, which correlated with clinical features such as vascular invasion and recurrence of disease after orthotopic liver transplantation. These data suggest that activation of beta-catenin signaling causes dedifferentiation to malignant, immature hepatocyte progenitors and facilitates recurrence of human HCC after orthotopic liver transplantation.

BACKGROUND: Carotid endarterectomy (CEA) is commonly performed for asymptomatic high-grade internal carotid artery (ICA) stenosis to prevent stroke. However, despite advancing age of the society, for patients older than 75 years, there is no recommendation by the European guidelines for CEA, as this age group might not benefit from this intervention due to a limited life expectancy. OBJECTIVE: We assessed N-terminal pro B-type natriuretic peptide (NT pro-BNP) as a predictive marker for long-term survival in this particular patient population in order to stratify patients for an improved surgical outcome. METHODS: In a nonrandomized single-center clinical trial, we prospectively studied mortality rates of 205 consecutive patients (80 women, 125 men; mean age, 75 ± 10 years) with asymptomatic high-grade ICA stenosis in relation to preoperative plasma NT pro-BNP levels. We estimated cumulative survival over 5 years by Kaplan-Meier curves and established a proportional hazard-model by Cox regression. RESULTS: In male patients, higher levels of preoperative NT pro-BNP levels were associated with a significantly increased long-term mortality. Those 75 years or older had the same survival rate as younger patients, if NT pro-BNP levels were low, making them thus eligible for CEA. CONCLUSIONS: The results of our study suggest that preoperative plasma levels of NT pro-BNP are a valuable tool for the stratification of male patients. Male patients older than 75 years with low levels of NT pro-BNP should be referred for carotid revascularization, as they will most likely enjoy the benefit of surgery.
