Health-related quality of life, work ability and disability among individuals with persistent post-dural puncture headache.

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.

Secular trends and regional pattern in body height of Austrian conscripts born between 1961 and 2002.

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.

Concurrent Validity and Test-Retest Reliability of the 3-Meter Backward Walk Test in Stroke Survivors.

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.

A country report: impact of COVID-19 lockdowns on involuntary psychiatric treatment in Austria.

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.

Lower educational level remains associated with lower body height among Austrian conscripts born from 1961 through 2002.

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.

The Association of Time of Day of ChAdOx1 nCoV-19 Vaccine Administration With SARS-CoV-2 Anti-Spike IgG Antibody Levels: An Exploratory Observational Study.

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.

Cut-off values of serum interleukin-6 for culture-confirmed sepsis in neonates.

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.

Alarming Increase of Ketoacidosis Prevalence at Type 1 Diabetes-Onset in Austria-Results From a Nationwide Registry.

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.

Seasonality in Major Depressive Disorder: Effect of Sex and Age.

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.

Use of complementary and alternative medicine and low quality of life associate with the need for psychological and psychotherapeutic interventions in inflammatory bowel disease.

INTRODUCTION: Patients with inflammatory bowel disease (IBD) suffer from various symptoms, impairing their quality of life and often affecting psychosocial issues. This may lead to the need for additional psychological care. This study investigated patients' subjective need for integrated psychosomatic support and psychotherapy and indicators for it. MATERIALS AND METHODS: This is a cross-sectional multicentre study in Austrian IBD patients who were in routine care at 18 IBD outpatient clinics. Patients filled in an anonymous, validated questionnaire (Assessment of the Demand for Additional Psychological Treatment Questionnaire [ADAPT]) assessing the need for psychological care. The ADAPT gives two separate scores: the need for integrated psychosomatic support and for psychotherapy. In addition, health-related quality of life and the use of complementary and alternative medicine as well as clinical and socio-demographic variables were queried. Multivariable regression analysis was performed to estimate the effect of the previously mentioned variables on the need for additional psychological care. RESULTS: Of 1286 patients, 29.7% expressed a need for additional psychological care, 19.6% expressed a need for integrated psychosomatic support and 20.2% expressed a need for psychotherapy. In the multivariable analysis, the two strongest indicators for the need for both types of psychological care were the use of complementary and alternative medicine (for integrated psychosomatic support: odds ratio = 1.64, 95% confidence interval 1.13-2.39, p = 0.010; for psychotherapy: odds ratio = 1.74, 95% confidence interval 1.20-2.53, p = 0.004), and a low health-related quality of life score (for integrated psychosomatic support: odds ratio = 0.95, 95% confidence interval 0.94-0.96, p < 0.001; for psychotherapy: odds ratio = 0.96, 95% confidence interval 0.94-0.97, p < 0.001). DISCUSSION: About 30% of the Austrian IBD patients expressed a need for integrated psychosomatic support and/or psychotherapy. The most important indicators for this need were the use of complementary and alternative medicine and low quality of life.

Pattern of inpatient care for depression: an analysis of 232,289 admissions.

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.

Thirty-five-year trend in the prevalence of refractive error in Austrian conscripts based on 1.5 million participants.

BACKGROUND: To quantify the current burden of myopia and hyperopia in Austrian young men and the time trend of myopia in the past 35 years by individual and social correlates. METHOD: We included data on all Austrian military conscripts from 1983 to 2017 (n=1 507 063) from six medical investigation stations. Young men provided data on education, weight and height for calculating body mass index, blood pressure and resting heart rate. Non-cycloplegic refractions were measured by an autorefractometer. Spherical equivalent was calculated by standard formula (sphere+cylinder/2, unit dioptres (D)). Myopic refractive error was defined as <-0.5 D). Hyperopic refractive error was defined as >0.5 D. RESULTS: The largest burden of refractive error in Austria is myopia, which rose from 13.8% to 24.4% over 35 years, with less than 5% hyperopic population. Over time, the prevalence of myopia was constantly lower yet increased more rapidly among those with low education levels (11.4%-21.7%) compared with those with higher education (24.5%-29.6%) in all medical investigation stations. We found consistent associations of some unfavourable health indicators (underweight: ORs 1.1-1.4, higher resting heart rate: all p trend <0.001) with higher myopia prevalence, which point towards lifestyle factors playing an important role in the development of myopia. CONCLUSION: Primary preventive measures are needed to curb the observed trend in myopia among Austrian young men. Future research should investigate the impact of modifiable factors on myopia development and progression, particularly lifestyle factors that are dramatically shifting.

Prevalence and indicators of use of complementary and alternative medicine in Austrian patients with inflammatory bowel disease.

OBJECTIVE: Complementary and alternative medicine (CAM) seems to be frequently used among patients with inflammatory bowel disease (IBD). We aimed to determine the prevalence and indicators of CAM use in Austrian IBD patients. METHODS: In a multicentre cross-sectional study, adult patients with IBD attending 18 Austrian outpatient clinics completed a multi-item questionnaire that recorded use of CAM as well as medical and socioeconomic characteristics. Patients were recruited between June 2014 and June 2015. The study outcome was the prevalence of CAM use and its socioeconomic and disease-related associations. RESULTS: A total of 1286 patients (Crohn's disease 830, ulcerative colitis 435, IBD unclassified 21; females 651) with a median age of 40 years (interquartile range 31-52 years) and a median disease duration of 10 years (4-18 years) were analysed. The prevalence of previous and/or current CAM use was 50.7%, with similar results for Crohn's disease and ulcerative colitis. In the multivariable analysis, female gender and a university education were independent socioeconomic indicators of CAM use. IBD-related indicators were longer duration of the disease and previous and/or current treatment with steroids and TNF-α inhibitors. CONCLUSION: CAM use for IBD is frequent in Austrian IBD patients and associated with female gender, higher educational level of university degree, longer duration of the disease, and treatment with steroids and TNF-α inhibitors.

Increased nurse workload is associated with bloodstream infections in very low birth weight infants.

Neonatal sepsis is a major cause of morbidity and mortality in very low birth weight infants (VLBWI). Nurse workload considerably affects infection rates in intensive care units. However, data concerning the impact of staff workload on bloodstream infections (BSI) in VLBWI are scarce. The aim of the study was to examine the association between nurse workload and BSI in VLBWI. VLBWI admitted to our neonatal intensive care unit during 2016-2017 were retrospectively analysed. Association between nurse workload, determined by a standardized nursing score, and the BSI occurrence was investigated. A higher nurse workload was significantly associated with higher occurrence of BSI (p = 0.0139) in VLBWI. An assumed workload of 120% or higher, representing the need for additional nurses in our NICU setting, is associated with an elevated risk for BSI in this vulnerable population OR 2.32 (95% CI: 1.42-3.8, p = 0.0005). In conclusion, nurse understaffing is associated with a higher risk for BSI in VLBWI.

Combination of Nasal and Expanded Skin Swabs Enhances the Detection Rate of Staphylococcus aureus Colonization in Premature Infants.

Nasal cultures are commonly used to detect carriers of Staphylococcus aureus (SA) in infants. Combination of nasal and skin swabs has been shown to enhance the detection rate of SA colonization in adult hospitalized patients. Combining nasal swabs with expanded body skin swabs enhanced detection of SA colonization in premature infants in a tertiary care neonatal department.

Diagnostic delay in patients with inflammatory bowel disease in Austria.

BACKGROUND: Delayed diagnosis seems to be common in inflammatory bowel diseases (IBD). The study was carried out to investigate the diagnostic delay and associated risk factors in Austrian IBD patients. METHODS: In a multicenter cross-sectional study adult patients with IBD attending 18 Austrian outpatient clinics completed a multi-item questionnaire that recorded medical and socioeconomic characteristics. The study outcome was diagnostic delay defined as the period from symptom onset to diagnosis of IBD. RESULTS: A total of 1286 patients (Crohn's disease 830, ulcerative colitis 435, inflammatory bowel disease unclassified 21; females 651) with a median age of 40 years (interquartile range 31-52 years) and a median disease duration of 10 years (4-18 years) were analyzed. The median diagnostic delay was 6 months (2-23 months) in Crohn's disease and 3 months (1-10 months) in ulcerative colitis (p < 0.001). In the multivariable regression analysis Crohn's disease, greater age at diagnosis and a high educational level (compared to middle degree level) were independently associated with longer diagnostic delay. CONCLUSION: The diagnostic delay was longer in Crohn's disease than in ulcerative colitis patients and was associated with greater age at diagnosis and a higher educational level.

Hand grip strength and cognitive function among elderly cancer survivors.

BACKGROUND: We evaluated the associations of handgrip strength and cognitive function in cancer survivors ≥ 60 years old using data from the National Health and Nutrition Examination Survey (NHANES). METHODS: Data in two waves of NHANES (2011-2014) were aggregated. Handgrip strength in kilogram (kg) was defined as the maximum value achieved using either hand. Two cognitive function tests were conducted among adults 60 years and older. The Animal Fluency Test (AFT) examines categorical verbal fluency (a component of executive function), and the Digital Symbol Substitution test (DSST) assesses processing speed, sustained attention, and working memory. Survey analysis procedures were used to account for the complex sampling design of the NHANES. Multiple linear regression models were used to estimate associations of handgrip strength with cognitive test scores, adjusting for confounders (age, gender, race/ethnicity, education, marital status, smoking status, depressive symptoms and leisure time physical activity). RESULTS: Among 383 cancer survivors (58.5% women, mean age = 70.9 years, mean BMI = 29.3 kg/m2), prevalent cancer types were breast (22.9%), prostate (16.4%), colon (6.9%) and cervix (6.2%). In women, each increase in kg of handgrip strength was associated with 0.20 (95% CI: 0.08 to 0.33) higher score on AFT and 0.83 (95% CI: 0.30 to 1.35) higher score on DSST. In men, we observed an inverted U-shape association where cognitive function peaked at handgrip strength of 40-42 kg. CONCLUSIONS: Handgrip strength, a modifiable factor, appears to be associated with aspects of cognitive functions in cancer survivors. Prospective studies are needed to address their causal relationship.

Left ventricular pumping during the transition-adaptation sequence in preterm infants: impact of the patent ductus arteriosus.

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.

Influence of gender on inpatient treatment for bipolar disorder: An analysis of 60,607 hospitalisations.

BACKGROUND: The influence of gender on inpatient treatment patterns in bipolar patients is unclear. The aim of this study is to examine whether differences in length of stay and frequency of inpatient episodes, according to ICD-10 bipolar disorder (BD)-subgroups, exist between men and women. METHODS: All episodes of a manic (F31.0-2), depressive (F31.3-5) or mixed (F31.6) subtype of BD during an inpatient stay in an Austrian hospital in the period of 2001-2014 were included in this study. Data on episodes was provided by the national statistics agency. Weekly admission rates per 100,000 people were calculated by directly age-standardized rates. RESULTS: The database comprised 60,607 admissions (35.8% men). The number of inpatient episodes was significantly higher (p < 0.001) in women in all BD subgroups. Average length of stay in manic (p < 0.001) and depressive (p < 0.001) episodes was shorter in women compared to men. No difference could be found for mixed episodes. LIMITATIONS: Only aggregated patient data and no single case histories were available for this study. CONCLUSIONS: The current study reveals relevant gender differences regarding inpatient treatment patterns, as women were overrepresented in all BD-subgroups. Despite equal life time prevalence, severe mood episodes lead more often to hospitalisations in women. There is a high necessity to further research the underlying causes of these findings.

Arterial catheterisation in neonates can result in severe ischaemic complications but does not impair long-term extremity function.

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.
