Implementation of an antimicrobial stewardship program for urinary tract infections in long-term care facilities: a cluster-controlled intervention study.

BACKGROUND: Widespread inappropriate use of antimicrobial substances drives resistance development worldwide. In long-term care facilities (LTCF), antibiotics are among the most frequently prescribed medications. More than one third of antimicrobial agents prescribed in LTCFs are for urinary tract infections (UTI). We aimed to increase the number of appropriate antimicrobial treatments for UTIs in LTCFs using a multi-faceted antimicrobial stewardship intervention. METHODS: We performed a non-randomized cluster-controlled intervention study. Four LTCFs of the Geriatric Health Centers Graz were the intervention group, four LTCFs served as control group. The main components of the intervention were: voluntary continuing medical education for primary care physicians, distribution of a written guideline, implementation of the project homepage to distribute guidelines and videos and onsite training for nursing staff. Local nursing staff recorded data on UTI episodes in an online case report platform. Two blinded reviewers assessed whether treatments were adequate. RESULTS: 326 UTI episodes were recorded, 161 in the intervention group and 165 in the control group. During the intervention period, risk ratio for inadequate indication for treatment was 0.41 (95% CI 0.19-0.90), p = 0.025. In theintervention group, the proportion of adequate antibiotic choices increased from 42.1% in the pre-intervention period, to 45.9% during the intervention and to 51% in the post-intervention period (absolute increase of 8.9%). In the control group, the proportion was 36.4%, 33.3% and 33.3%, respectively. The numerical difference between intervention group and control group in the post-intervention period was 17.7% (difference did not reach statistical significance). There were no significant differences between the control group and intervention group in the safety outcomes (proportion of clinical failure, number of hospital admissions due to UTI and adverse events due to antimicrobial treatment). CONCLUSIONS: An antimicrobial stewardship program consisting of practice guidelines, local and web-based education for nursing staff and general practitioners resulted in a significant increase in adequate treatments (in terms of decision to treat the UTI) during the intervention period. However, this difference was not maintained in the post-intervention phase. Continued efforts to improve the quality of prescriptions further are necessary. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov NCT04798365.

Predictors of adherence in Austrian employees during the COVID-19 pandemic: results of an online survey.

Background: Since the beginning of the pandemic in December 2019, Coronavirus disease 2019 (COVID-19) has been a significant challenge to health care systems throughout the world. The introduction of measures to reduce the incidence of infection had a significant impact on the workplace. Overall, companies played a key and adaptive role in coping with the pandemic. Methods: Cross-sectional data from an online-survey of 1,183 employees conducted during the COVID-19 pandemic in spring 2021 in Austria were used in the analyses. The influence of health beliefs (e.g., perceived severity), modifying factors (e.g., age) and time-dependent factors (e.g., corona fatigue) on individual adherence were evaluated. The conception of the questionnaire was based on the health belief model. Results: The majority of respondents were female (58.3%), worked in companies with more than 250 employees (56.6%) and had been to an academic secondary school or had a university degree (58.3%). Overall, employees were adherent to most of the measures at their company (>80%), except for wearing FFP-2 masks when they were travelling in a car with coworkers (59.3, 95%CI 51.3-66.7%). Overall adherence was associated with high ratings for the meaningfulness of testing (OR: 2.06 95%CI: 1.00-4.22; p = 0.049), the extent to which social norms govern behavior (OR: 6.61 95%CI: 4.66-9.36; p < 0.001), lower perceived difficulties associated with the adoption of health-promoting measures (OR: 0.37 95%CI: 0.16-0.82; p = 0.015) and lower corona fatigue (OR: 0.23 95%CI: 0.10-0.52; p < 0.001). Adherence to four single measures was influenced by different predictors. The most important predictors (important for the adherence to three out of four single measures) were social norms and corona fatigue. Conclusion: The importance attached to testing and social norms, as well as lower perceived barriers to health-promoting measures and low levels of corona fatigue all increase overall adherence to Covid-19 protective measures in companies. Strategies to improve adherence should be adapted depending on the aim (to raise overall adherence or adherence to individual measures) and on the group of persons that is being targeted.

Compartment-specific remodeling patterns in end-stage chronic obstructive pulmonary disease with and without severe pulmonary hypertension.

BACKGROUND: In patients with end-stage chronic obstructive pulmonary disease (COPD), severe pulmonary hypertension (PH) is frequently associated with less severe airway obstruction as compared to mild or no PH. However, the histologic correlate of this finding is not clear. We aimed to quantify remodeling of pulmonary arteries, airways, and parenchyma in random samples of explanted end-stage COPD lungs. METHODS: We quantified remodeling of small pulmonary arteries, small airways, and the degree of emphysema (mean interseptal distance [MID]) with dedicated software. As primary objective, we compared COPD patients with severe PH (SevPH-COPD) with age- and sex-matched MildPH-COPD. For comparison, we also investigated COPD lungs with no PH (NoPH-COPD), idiopathic PAH (IPAH), and healthy donors. RESULTS: We included n = 17 SevPH-COPD (mPAP = 43 [39-45]mm Hg), n = 17 MildPH-COPD (mPAP = 28 [24-31]mm Hg), n = 5 NoPH-COPD (mPAP = 18 [16-19]mm Hg), n = 10 IPAH (mPAP = 72 [65-91]mm Hg), and n = 10 healthy donor lungs. SevPH-COPD versus MildPH-COPD was characterized by better preserved forced vital capacity (51% vs 40% predicted, p < 0.05), less emphysema (MID 169 µm vs 279 µm, p < 0.001), and less PAS-positive and CD45-positive mucosa cells (15% vs 22%, p = 0.063% and 5% vs 7%, p = 0.058) suggesting less airway inflammation. In COPD patients, intimal and medial thickening were strongly correlated with mPAP (r = 0.676, p < 0.001 and r = 0.595, p < 0.001). MID was negatively correlated with mPAP (r = -0.556, p < 0.001) and was highest in NoPH-COPD (mean 281 µm), suggesting that emphysema per se is not associated with PH. CONCLUSIONS: End-stage COPD with severe PH is characterized by pronounced pulmonary vascular remodeling, less inflammation of small airways, and less emphysema as compared to COPD with mild PH or no PH, suggesting that COPD with severe PH may represent a unique phenotype of COPD.

Measuring patient activation: the utility of the Patient Activation Measure administered in an interview setting.

BACKGROUND: Patient activation is an emerging field in healthcare research concerning knowledge, skills, and confidence of patients in managing their health. This is particularly important for patients with chronic diseases, who often require more complex care management and self-care skills. However, due to temporary or longer-lasting visual impairments, certain patient groups cannot answer a questionnaire independently. The main objective is to investigate the psychometric properties of the German Patient Activation Measure® (PAM) survey in an everyday clinical setting where it has to be read aloud. METHODS: Outpatients with macular edema participated in this questionnaire-based cross-sectional study. The study assessed patient activation by the PAM® survey, self-rated health, self-efficacy, quality of life, and general mood. Interviewers read questionnaires aloud to patients. Psychometric properties of the PAM® survey were investigated by item response theory (IRT), Cronbach's α and trait-trait correlations. RESULTS: The analysis included N = 554 patients. Median age was 69 (IQR 62.0-76.0) years and mean overall activation score 74.1 (SD 13.7). All items showed ceiling effects. Empirical reliability from the IRT model and Cronbach's α were 0.75. The PAM® survey showed a Spearman correlation of 0.54 with self-efficacy, 0.51 with quality of life and 0.34 with general mood. CONCLUSION: The read-aloud PAM® survey has been shown to provide to adequate measurement precision and convergent validity to be used as a screening tool in an everyday clinical setting. Objective assessment in an interview setting with the PAM® survey is possible. PAM® items are good in distinguishing lower to middle activated patients, but not patients with high activation. Further, issues with structural validity need more investigation.

Numeric rating scale for pain should be used in an ordinal but not interval manner. A retrospective analysis of 346,892 patient reports of the quality improvement in postoperative pain treatment registry.

ABSTRACT: To assess postoperative pain intensity in adults, the numeric rating scale (NRS) is used. This scale has shown acceptable psychometric features, although its scale properties need further examination. We aimed to evaluate scale properties of the NRS using an item response theory (IRT) approach. Data from an international postoperative pain registry (QUIPS) was analyzed retrospectively. Overall, 346,892 adult patients (age groups: 18-20 years: 1.6%, 21-30 years: 6.7%, 31-40 years: 8.3%, 41-50 years: 13.2%, 51-60 years: 17.1%, 61-70 years: 17.3%, 71-80 years: 16.4%, 81-90 years: 3.9%, >90: 0.2%) were included. Among the patients, 55.7% are female and 38% had preoperative pain. Three pain items (movement pain, worst pain, least pain) were analyzed using 4 different IRT models: partial credit model (PCM), generalized partial credit model (GPCM), rating scale model (RSM), and graded response model (GRM). Fit indices were compared to decide the best fitting model (lower fit indices indicate a better model fit). Subgroup analyses were done for sex and age groups. After collapsing the highest and the second highest response category, the GRM outperformed other models (lowest Bayesian information criterion) in all subgroups. Overlapping categories were found in category boundary curves for worst and minimum pain and particularly for higher pain ratings. Response category widths differed depending on pain intensity. For female, male, and age groups, similar results were obtained. Response categories on the NRS are ordered but have different widths. The interval scale properties of the NRS should be questioned. In dealing with missing linearity in pain intensity ratings using the NRS, IRT methods may be helpful.

Precision and normal values of cerebral blood volume in preterm neonates using time-resolved near-infrared spectroscopy.

AIM: To investigate cerebral blood volume (CBV) in preterm neonates using time-resolved near-infrared spectroscopy. METHODS: In this prospective observational study, time-resolved near-infrared spectroscopy measurements of CBV using tNIRS-1 were performed in 70 preterm neonates. For measurements, a sensor was placed for a duration of 1 min, followed by four further reapplications of the sensor, overall five measurements. RESULTS: In this study, 70 preterm neonates with a mean ± SD gestational age of 33.4 ± 1.7 weeks and a birthweight of 1931 ± 398 g were included with a postnatal age of 4.7 ± 2.0 days. Altogether, 2383 CBV values were obtained with an overall mean of 1.85 ± 0.30 mL/100 g brain. A total of 95% of the measured CBV values varied in a range from -0.31 to 0.33 from the overall individual mean. Taking the deviation of the mean of each single application for each patient, this range reduced from -0.07 to 0.07. The precision of the measurement defined as within-variation in CBV was 0.24 mL/100 g brain. CONCLUSION: The overall mean CBV in stable preterm neonates was 1.85 ± 0.30 mL/100 g brain. The within-variation in CBV was 0.24 mL/100 g brain. Based on the precision obtained by our data, CBV of 1.85 ± 0.30 mL/100 g brain may be assumed as normal value for this cohort.

Is PONV still a problem in pediatric surgery: a prospective study of what children tell us.

Background: Postoperative nausea and vomiting (PONV) is an unpleasant complication after surgery that commonly co-occurs with pain. Considering the high prevalence among pediatric patients, it is important to explore the main risk factors leading to PONV in order to optimize treatment strategies. The objectives of this study are as follows: (1) to determine the prevalence of PONV on the day of surgery by conducting interviews with pediatric patients, (2) to assess PONV prevalence in the recovery room and on the ward by analyzing nursing records, and (3) to collect information on PONV risk factors on the day of surgery and the following postoperative days. We wanted to investigate real-life scenarios rather than relying on artificially designed studies. Methods: A prospective analysis [according to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) guidelines] of PONV on the day of surgery and the following postoperative days was conducted by evaluating demographic and procedural parameters, as well as conducting interviews with the children under study. A total of 626 children and adolescents, ranging in age from 4 to 18 years, were interviewed on the ward following their surgery. The interviews were conducted using a questionnaire, as children aged 4 and above can participate in an outcome-based survey. Results: On the day of surgery, several multivariable independent predictors were identified for PONV. The type of surgery was found to be a significant factor (p = 0.040) with the highest odds ratio (OR) in patients with procedural investigations [OR 5.9, 95% confidence interval (CI): 1.8-19.2], followed by abdominal surgery (OR 3.1, 95% CI: 0.9-11.1) when inguinal surgery was used as the reference category. In addition, the study identified several predictors, including the amount of fentanyl administered during anesthesia (µg/kg body weight) (OR 1.4, 95% CI: 1.1-1.8), intraoperative use of piritramide (OR 2.6, 95% CI: 1.5-4.4) and diclofenac (OR 2.0, 95% CI: 1. 3-3.1), opioid administration in the recovery room (OR 3.0, 95% CI: 1.9-4.7), and piritramide use on the ward (OR 4.5, 95% CI: 1.7-11.6). Conclusions: The main risk factors for PONV include the intraoperative administration of opioids during the recovery room stay and at the ward, the intraoperative use of non-opioids (diclofenac), and the specific type of surgical procedure. Real-life data demonstrated that in clinical praxis, there is a gap between the adherence to established guidelines and the use of antiemetic prophylaxis in surgeries that are generally not associated with a high PONV prevalence. Further efforts are needed to improve the existing procedures and thus improve the overall outcome.

Peripheral muscle fractional tissue oxygen extraction in stable term and preterm neonates during the first 24†h after birth.

Background: Peripheral muscle fractional tissue oxygen extraction (pFTOE) represents the relative extraction of oxygen from the arterial to venous compartment, providing information about dynamic changes of oxygen delivery and oxygen consumption. The aim of the present study was to establish reference values of pFTOE during the first 24 h after birth in stable term and late preterm neonates. Methods: The present study is a post-hoc analysis of secondary outcome parameters of prospective observational studies. Only stable neonates without infection, asphyxia and any medical support were eligible for our analysis to obtain normal values. For measurements of peripheral muscle tissue oxygenation index (pTOI) during the first 24 h after birth in term and preterm neonates, the NIRO200/NIRO200NX was used. Arterial oxygen saturation (SpO2) was obtained by pulse oximetry. pFTOE was calculated out of pTOI and SpO2: pFTOE = (SpO2-pTOI)/SpO2. Measurements of neonates were stratified into four groups according to their respective measurement time point (6 h periods) after birth. Term and preterm neonates were analyzed separately. Mean values of measurements during the first time period (0-6 h after birth) were compared to measurements of the following time periods (second = 7-12 h, third = 13-18 h, fourth = 19-24 h after birth). Results: Two-hundred-fourty neonates (55 term and 185 late preterm neonates) had at least one peripheral muscle NIRS measurements within the first 24 h after birth. Mean gestational age and birth weight were 39.4 ± 1.1 weeks and 3360 (2860-3680)g in term neonates and 34.0 ± 1.4 weeks and 2060 (1750-2350)g in preterm neonates, respectively. In term neonates pFTOE was 0.264 (0.229-0.300), 0.228 (0.192-0.264), 0.237 (0.200-0.274) and 0.220 (0.186-0.254) in the first, second, third and fourth time period. In preterm neonates pFTOE was 0.229 (0.213-0.246), 0.225 (0.209-0.240), 0.226 (0.210-0.242) and 0.238 (0.222-0.255) in the first, second, third and fourth time period. pFTOE did not show any significant changes between the time periods, neither in term nor in preterm neonates. Conclusion: We provide reference values of pFTOE for stable term and late preterm neonates within the first 24 h after birth, which were stable when comparing four 6-h periods. These normal values are of great need for interpreting pFTOE in scientific context as well as for potential future clinical applications.

Palliative Care Survey: Awareness, Knowledge and Views of the Styrian Population in Austria.

BACKGROUND: No population-based data on awareness and knowledge of palliative care currently exist in Austria. We therefore conducted a survey to determine the general awareness and knowledge of palliative care in Styria, a federal state in Austria. We also asked participants to imagine what services they would need as a patient or family member, where they themselves would like to receive such services, and what fears they imagined patients with a terminal illness would have. METHODS: A descriptive cross-sectional survey consisting of 18 questions that address several aspects of palliative care was carried out in the adult population of Styria, Austria, from October 2019 to March 2020. RESULTS: A total of 419 questionnaires were analyzed, whereby 70.3% of respondents had at least heard of palliative care. Of these, significantly more were female, had a university degree and were aged 50 to 64. The main goal of palliative care was chosen correctly by 67.1% of participants, with the proportion of correct answers increasing in line with education and reaching 82.0% among university graduates. Overall, 73.2% believed that the greatest need of terminally ill persons was a reduction in physical suffering, whereas the greatest perceived need of relatives was the availability of specialist care around the clock. About one-third believed that the greatest fear of palliative patients was that of death, which was chosen significantly more often by men than women. If terminally ill, some 39% of respondents would wish to be looked after at home by professional carers, and women and people that had completed high school chose this answer significantly more often. The most desired service that should be provided to patients and relatives was home pain management at 69.9%, followed by time off for family caregivers at 58.0%. This item was chosen significantly more often by women. CONCLUSIONS: To facilitate the care of severely ill patients at home, it would make sense to develop targeted information campaigns. These should also attempt to deliver targeted information to less informed groups of people, such as young, poorly educated men, in order to raise their awareness of the difficulties and challenges of providing care to terminally ill patients and thus increase the acceptance of support options.

Do Sex-Specific Factors Influence the Surgical Treatment of Facial Skin Cancer?

Facial skin cancer (FSC) is prone to incomplete excision due to the sophisticated anatomy and the aesthetic importance of the face. In this study, we sought to investigate to what extent sex-specific differences and other operation-, patient-, and cancer-specific factors influence the re-resection rate in FSC surgery, in order to provide personalized treatment strategies to patients. In this retrospective study, patients (>18 years) undergoing surgical excision of an FSC were enrolled. Each patient's demographic data, cancer location, the surgical team, primary and secondary surgeries were analyzed. Overall, 469 patients (819 surgeries) were included. The mean age was 69 ± 15 years. No significant association between sex-specific factors (surgeon's sex (OR: 1.09, 95% CI: 0.76-1.56) or patient's sex (OR: 0.85, 95% CI: 0.62-1.17), surgeon-patient sex concordance and discordance) and the likelihood of secondary surgery were found. However, healing by secondary intention (OR: 4.28; 95% CI: 1.94-9.45) and cancer location showed an increased re-resection rate. In conclusion, FSC surgery is a safe method unaffected by sex-specific factors, which had no impact on the re-resection rate. However, in further analysis, the likelihood of a re-resection was influenced by other factors such as healing by secondary intention and cancer location. This knowledge might be useful to provide an algorithm for personalized treatment strategies in the future.

Identifying key policy objectives for strong primary care: a cross-sectional study.

AIM: The aim of this study was to identify key policy objectives by investigating the perception of important stakeholders and affected professionals concerning relevance and feasibility of a successful primary care (PC) reform. BACKGROUND: Since 2013, the Austrian PC system has been undergoing a reform process to establish multiprofessional primary care units. The reforms have various defined objectives and lack clear priorities. METHODS: After the definition and consensus-based selection of 12 policy objectives, a cross-sectional online survey on their relevance and feasibility was distributed via email and social media to PC and public health networks. The survey was conducted in the period from January to February 2020. Results were analyzed descriptively, and further, Pearson Chi-Square Test or Fisher's Exact Test was performed for group comparison regarding respondents' characteristics. Open-ended responses were analyzed using qualitative content analysis. FINDINGS: In total, 169 questionnaires were completed. A total of 46.3% of the responders had more than 20 years of professional experience (female: 60.5%). A mandatory internship in general practice, vocational training for general practice, and a modern remuneration system were the three top-rated policy objectives regarding relevance. A mandatory internship in general practice, specialization in general practice, and coding of services and diagnosis were assessed as the most feasible objectives. The group comparisons regarding working field, years of professional experience, age, and sex did not show any meaningful results in the evaluation of relevance and feasibility. DISCUSSION: In the view of the study participants, easily obtainable objectives include adapting the duration and setting of internships for medical students, as well as mandatory vocational training for GP trainees. Further efforts are necessary to achieve complex objectives such as the adoption of a modern remuneration scheme and a comprehensive quality assurance program. Building capacity and creating team-oriented environments are also important aspects of a successful PC reform.

Cerebral oxygenation immediately after birth and long-term outcome in preterm neonates-a retrospective analysis.

BACKGROUND: Prematurity is associated with increased risk for morbidity and mortality. Aim of this study was to evaluate whether cerebral oxygenation during fetal-to-neonatal transition period was associated with long-term outcome in very preterm neonates. METHODS: Preterm neonates ≤ 32 weeks of gestation and/or ≤ 1500 g with measurements of cerebral regional oxygen saturation (crSO2) and cerebral fractional tissue oxygen extraction (cFTOE) within the first 15 min after birth were analysed retrospectively. Arterial oxygen saturation (SpO2) and heart rate (HR) were measured with pulse oximetry. Long-term outcome was assessed at two years using "Bayley Scales of Infant Development" (BSID-II/III). Included preterm neonates were stratified into two groups: adverse outcome group (BSID-III ≤ 70 or testing not possible due to severe cognitive impairment or mortality) or favorable outcome group (BSID-III > 70). As the association between gestational age and long-term outcome is well known, correction for gestational age might disguise the potential association between crSO2 and neurodevelopmental impairment. Therefore, due to an explorative approach the two groups were compared without correction for gestational age. RESULTS: Forty-two preterm neonates were included: adverse outcome group n = 13; favorable outcome group n = 29. Median(IQR) gestational age and birth weight were 24.8 weeks (24.2-29.8) and 760 g (670-1054) in adverse outcome group and 30.6 weeks (28.1-32.0) (p = 0.009*) and 1250 g (972-1390) (p = 0.001*) in the favorable outcome group, respectively. crSO2 was lower (significant in 10 out of 14 min) and cFTOE higher in adverse outcome group. There were no difference in SpO2, HR and fraction of inspired oxygen (FiO2), except for FiO2 in minute 11, with higher FiO2 in the adverse outcome group. CONCLUSION: Preterm neonates with adverse outcome had beside lower gestational age also a lower crSO2 during immediate fetal-to-neonatal transition when compared to preterm neonates with age appropriate outcome. Lower gestational age in the adverse outcome group would suggest beside lower crSO2 also lower SpO2 and HR in this group, which were however similar in both groups.

Gender Differences in Perceived Working Conditions of General Practitioners During the COVID-19 Pandemic-a Cross-Sectional Study.

BACKGROUND: The ongoing COVID-19 pandemic has revealed gender-specific differences between general practitioners in adapting to the posed challenges. As primary care workforce is becoming increasingly female, in many countries, it is essential to take a closer look at gender-specific influences when the global health care system is confronted with a crisis. OBJECTIVE: To explore gender-specific differences in the perceived working conditions and gender-specific differences in challenges facing GPs at the beginning of the COVID-19 pandemic in 2020. DESIGN: Online survey in seven countries. PARTICIPANTS: 2,602 GPs from seven countries (Austria, Australia, Switzerland, Germany, Hungary, Italy, Slovenia). Of the respondents, 44.4% (n = 1,155) were women. MAIN MEASURES: Online survey. We focused on gender-specific differences in general practitioners' perceptions of working conditions at the beginning of the COVID-19 pandemic in 2020. KEY RESULTS: Female GPs rated their skills and self-confidence significantly lower than male GPs (f: 7.1, 95%CI: 6.9-7.3 vs. m: 7.6, 95%CI 7.4-7.8; p < .001), and their perceived risk (concerned about becoming infected or infecting others) higher than men (f: 5.7, 95%CI: 5.4-6.0 vs. m: 5.1, 95%CI: 4.8-5.5; p = .011). Among female GPs, low self-confidence in the treatment of COVID-19 patients appear to be common. Results were similar in all of the participating countries. CONCLUSIONS: Female and male GPs differed in terms of their self-confidence when dealing with COVID-19-related issues and their perceptions of the risks arising from the pandemic. To ensure optimal medical care, it is important that GPs realistically assess their own abilities and overall risk.

Cerebral regional tissue Oxygen Saturation to Guide Oxygen Delivery in preterm neonates during immediate transition after birth (COSGOD III): multicentre randomised phase 3 clinical trial.

OBJECTIVE: To investigate whether monitoring of cerebral tissue oxygen saturation using near infrared spectroscopy in addition to routine monitoring combined with defined treatment guidelines during immediate transition and resuscitation increases survival without cerebral injury of premature infants compared with standard care alone. DESIGN: Multicentre, multinational, randomised controlled phase 3 trial. SETTING: 11 tertiary neonatal intensive care units in six countries in Europe and in Canada. PARTICIPANTS: 1121 pregnant women (<32 weeks' gestation) were screened prenatally. The primary outcome was analysed in 607 of 655 randomised preterm neonates: 304 neonates in the near infrared spectroscopy group and 303 in the control group. INTERVENTION: Preterm neonates were randomly assigned to either standard care (control group) or standard care plus monitoring of cerebral oxygen saturation with a dedicated treatment guideline (near infrared spectroscopy group) during immediate transition (first 15 minutes after birth) and resuscitation. MAIN OUTCOME MEASURE: The primary outcome, assessed using all cause mortality and serial cerebral ultrasonography, was a composite of survival without cerebral injury. Cerebral injury was defined as any intraventricular haemorrhage or cystic periventricular leukomalacia, or both, at term equivalent age or before discharge. RESULTS: Cerebral tissue oxygen saturation was similar in both groups. 252 (82.9%) out of 304 neonates (median gestational age 28.9 (interquartile range 26.9-30.6) weeks) in the near infrared spectroscopy group survived without cerebral injury compared with 238 (78.5%) out of 303 neonates (28.6 (26.6-30.6) weeks) in the control group (relative risk 1.06, 95% confidence interval 0.98 to 1.14). 28 neonates died (near infrared spectroscopy group 12 (4.0%) v control group 16 (5.3%): relative risk 0.75 (0.33 to 1.70). CONCLUSION: Monitoring of cerebral tissue oxygen saturation in combination with dedicated interventions in preterm neonates (<32 weeks' gestation) during immediate transition and resuscitation after birth did not result in substantially higher survival without cerebral injury compared with standard care alone. Survival without cerebral injury increased by 4.3% but was not statistically significant. TRIAL REGISTRATION: ClinicalTrials.gov NCT03166722.

Salivary potassium measured by genetically encoded potassium ion indicators as a surrogate for plasma potassium levels in hemodialysis patients-a proof-of-concept study.

BACKGROUND: Hyperkalemia is a common complication in cardiorenal patients treated with agents interfering with renal potassium (K+) excretion. It frequently leads to discontinuation of potentially life-saving medication, which has increased the importance of K+ monitoring. Non-invasive means to detect hyperkalemia are currently unavailable, but would be of potential use for therapy guidance. The aim of the present study was to assess the analytical performance of genetically encoded potassium-ion indicators (GEPIIs) in measuring salivary [K+] ([K+]Saliva) and to determine whether changes of [K+]Saliva depict those of [K+]Plasma. METHODS: We conducted this proof-of-concept study: saliva samples from 20 healthy volunteers as well as plasma and saliva from 29 patients on hemodialysis (HD) before and after three consecutive HD treatments were collected. We compared [K+]Saliva as assessed by the gold standard ion-selective electrode (ISE) with GEPII measurements. RESULTS: The Bland-Altmann analysis showed a strong agreement (bias 0.71; 95% limits of agreement from -2.79 to 4.40) between GEPII and ISE. Before treatment, patients on HD showed significantly higher [K+]Saliva compared with healthy controls [median 37.7 (30.85; 48.46) vs 23.8 (21.63; 25.23) mmol/L; P < .05]. [K+]Plasma in HD patients decreased significantly after dialysis. This was paralleled by a significant decrease in [K+]Saliva, and both parameters increased until the subsequent HD session. Despite similar kinetics, we found weak or no correlation between [K+]Plasma and [K+]Saliva. CONCLUSION: GEPIIs have shown an excellent performance in determining [K+]Saliva. [K+]Plasma and [K+]Saliva exhibited similar kinetics. To determine whether saliva could be a suitable sample type to monitor [K+]Plasma, further testing in future studies are required.

Vaginal laser therapy versus hyaluronic acid suppositories for women with symptoms of urogenital atrophy after treatment for breast cancer: A randomized controlled trial.

BACKGROUND: Urogenital atrophy affects >50 % of women after breast cancer (BC) and there is reluctance to use local estrogen for this group. Hormone-free therapies like intravaginal laser therapy and hyaluronic acid suppositories have been shown to produce symptom relief in women with BC and urogenital atrophy, but have not been tested against each other. The aim of this study was to compare these nonhormonal modalities in women with urogenital atrophy after BC in a randomized fashion. STUDY DESIGN: We randomly assigned 43 women (aged 49-58 years, mean age 54 years) with urogenital atrophy and a history of BC to receive intravaginal laser therapy (2 courses within 1 month) or hyaluronic acid suppositories (3 times/week continuously for three months). The primary endpoint was score on the Vaginal Health Index after 3 months. Secondary endpoints were subjective bother on a numeric rating scale for all urogenital atrophy domains, quality of life, sexual health and pelvic organ prolapse symptoms using validated questionnaires. RESULTS: Of the 43 women who participated, 22 were randomized to intravaginal laser therapy, and 21 to vaginal suppositories. At 3 months score on the Vaginal Health Index had improved significantly in both groups (p = 0.001), without a significant difference between treatment groups (p = 0.232). Significant improvement was also seen in both groups for subjective bother of urogenital atrophy, quality of life and sexual health, without significant differences between laser or hyaluronic acid therapy. CONCLUSIONS: Both intravaginal laser therapy and hyaluronic acid suppositories are effective treatment options for women after BC suffering from urogenital atrophy. No difference was found between treatment regimens. CLINICALTRIALS: gov identifier: NCT03816735, https://clinicaltrials.gov/ct2/show/NCT03816735.

Predictors for adherent behavior in the COVID-19 pandemic: A cross-sectional telephone survey.

Background: During the COVID-19 pandemic, protective measures have been prescribed to prevent or slow down the spread of the SARS-CoV-2 virus and protect the population. Individuals follow these measures to varying degrees. We aimed to identify factors influencing the extent to which protective measures are adhered to. Methods: A cross-sectional survey (telephone interviews) was undertaken between April and June 2021 to identify factors influencing the degree to which individuals adhere to protective measures. A representative sample of 1,003 people (age >16 years) in two Austrian states (Carinthia, Vorarlberg) was interviewed. The questionnaire was based on the Health Belief Model, but also included potential response-modifying factors. Predictors for adherent behavior were identified using multiple regression analysis. All predictors were standardized so that regression coefficients (ß) could be compared. Results: Overall median adherence was 0.75 (IQR: 0.5-1.0). Based on a regression model, the following variables were identified as significant in raising adherence: higher age (ß = 0.43, 95%CI: 0.33-0.54), social standards of acceptable behavior (ß = 0.33, 95%CI: 0.27-0.40), subjective/individual assessment of an increased personal health risk (ß = 0.12, 95%CI: 0.05-0.18), self-efficacy (ß = 0.06, 95%CI: 0.02-0.10), female gender (ß = 0.05, 95%CI: 0.01-0.08), and low corona fatigue (behavioral fatigue: ß = -0.11, 95%CI: -0.18 to -0.03). The model showed that such aspects as personal trust in institutions, perceived difficulties in adopting health-promoting measures, and individual assessments of the risk of infection, had no significant influence. Conclusions: This study reveals that several factors significantly influence adherence to measures aimed at controlling the COVID-19 pandemic. To enhance adherence, the government, media, and other relevant stakeholders should take the findings into consideration when formulating policy. By developing social standards and promoting self-efficacy, individuals can influence the behavior of others and contribute toward coping with the pandemic.

Pulmonary vascular disease and exercise hemodynamics in chronic liver disease.

BACKGROUND & AIMS: Portopulmonary hypertension (POPH) and hepatopulmonary syndrome (HPS) are severe pulmonary vascular complications of chronic liver disease and strongly associated with morbidity and mortality. The prevalence of these complications is relatively high in patients evaluated for liver transplantation, however it is virtually unknown in patients with stable chronic liver disease. METHODS: We assessed the pulmonary hypertension (PH) and HPS prevalence in a prospective registry study of our liver out-patient clinic in a tertiary center. Between 2011 and 2016, consecutive patients with cirrhosis or non-cirrhotic portal hypertension were prospectively enrolled after written informed consent. We excluded patients with acute decompensation of liver disease and other causes of PH like severe chronic heart or lung diseases and chronic thromboembolic PH. HPS was diagnosed using contrast enhanced echocardiography and blood gas analysis. Patients were screened for PH using an algorithm implementing severity of dyspnea, echocardiography, cardiopulmonary exercise testing and exercise echocardiography employing a threshold of systolic pulmonary arterial pressure (SPAP) = 50 mmHg at peak exercise. If the algorithm indicated an increased PH risk, patients were invited for invasive investigations by means of right heart and hepatic vein catheter. We defined POPH as resting mPAP≥21 mmHg and PVR>3WU and PAWP<15 mmHg, mild PH as resting mPAP = 21-24 mmHg, and exercise PH as mPAP>30 mmHg and TPR >3 WU at peak exercise. RESULTS: Two-hundred-five patients were enrolled (male 75%; cirrhosis 96%; median age 57 yrs). Sixty-seven patients (33%) fulfilled HPS criteria but only two (1.0%) for severe (PaO2:50-60 mmHg) or very severe HPS (PaO2<50 mmHg). In 18/77 patients (23%) undergoing exercise echocardiography, SPAP at peak exercise exceeded 50 mmHg. Finally, n = 3 (1.5%) patients were invasively diagnosed with POPH, n = 4 (2.9%) with mild PH and n = 2 with exercise PH. CONCLUSION: In chronic liver disease, excluding acute decompensation and other causes of PH, POPH and severe HPS are rare findings while mild to moderate HPS and mild PH or exercise PH are more frequent.

Normal Echocardiographic Reference Values of the Right Ventricular to Left Ventricular Endsystolic Diameter Ratio and the Left Ventricular Endsystolic Eccentricity Index in Healthy Children and in Children With Pulmonary Hypertension.

Background: An accurate assessment of the right and left ventricle and their interaction is important in pediatric pulmonary hypertension (PH). Our objective was to provide normal reference values for the right ventricular to left ventricular endsystolic (RV/LVes) ratio and the LV endsystolic eccentricity index (LVes EI) in healthy children and in children with PH. Methods: We conducted an echocardiographic study in 769 healthy children (median age: 3.36 years; range: 1 day-18 years) and validated abnormal values in 44 children with PH (median age: 2.1 years; range: 0.1 months-17.7 years). We determined the effects of gender, age, body length, body weight, and body surface area (BSA) on RV/LVes ratio and LVes EI values. The RV/LVes ratio and LVes EI were measured from the parasternal short axis view between papillary muscle from the endocardial to endocardial surfaces. Results: Both, the RV/LVes ratio and the LVes EI were highly age-dependent: (i) neonates RV/LVes ratio [median 0.83 (range 0.53-1.37)], LVes EI [1.21 (0.92-1.45)]; (ii) 12-24 months old: RV/LVes ratio: [0.55 (0.35-0.80)], LVes EI: [1.0 (0.88-1.13)]; iii) 18th year of life RV/LVes ratio: [0.53 (0.32-0.74)], LVes EI: [1.0 (0.97-1.07)]. Healthy neonates had high LVes EI and RV/LVes ratios, both gradually decreased within the first year of life and until BSA values of about 0.5 m2, body weight to about 15 kg and body length to about 75 cm, but were almost constant thereafter. Children (>1 year) and adolescents with PH had significantly higher RV/LVes ratio (no PH: median 0.55, IQR 0.49-0.60; PH: 1.02, 0.87-1.26; p < 0.001) and higher LVes EI values (no PH: 1.00, 0.98-1.00; PH: 1.53, 1.26-1.71; p < 0.001) compared to those without PH. To predict the presence of PH in children > 1 year, we found the following best cutoff values: RV/LVes ratio ≥ 0.67 (sensitivity: 1.00, specificity: 0.95) and LVes EI ≥ 1.06 (sensitivity: 1.00, specificity: 0.97). Conclusion: We provide normal echocardiographic reference values of the RV/LVes ratio and LVes EI in healthy children, as well as statistically determined cutoffs for the increased values in children with PH.
