Abstract
OBJECTIVES Numerous animal and epidemiologic studies have demonstrated a positive association between maternal obesity in pregnancy and obesity in offspring. The biologic mechanisms of this association remain under investigation. One proposed mechanism includes fetoplacental endothelial dysfunction secondary to inflammation. Endocan is a relatively new biomarker for endothelial dysfunction and inflammation. Our objectives were to examine (1) the association between maternal obesity and neonatal serum endocan at birth, and (2) the association between neonatal serum endocan at birth and pediatric obesity at 24-36 months of age. STUDY DESIGN This was a secondary analysis of a prospective cohort of neonates born < 33 weeks gestation. Serum endocan was collected within 48 hours of birth. Serum endocan levels were compared in neonates born to obese mothers vs. those born to non-obese mothers. BMI data were retrospectively collected from cohort neonates between 24 and 36 months of age. RESULTS The analysis included 120 mother/neonate dyads. Neonates born to obese mothers had higher median serum endocan at birth compared to neonates born to non-obese mothers (299 ng/L [205-586] vs. 251 ng/L [164-339], p = 0.045). In a linear regression modeled on neonatal serum endocan level, maternal obesity had a statistically significant positive association (p = 0.021). Higher mean serum endocan level at birth was associated with pediatric obesity between 24 and 36 months (obese vs. non-obese offspring; 574 ng/L (222) vs. 321 ng/L (166), p = 0.005). CONCLUSIONS In our cohort of preterm neonates, elevated serum endocan at birth was associated with both maternal obesity and downstream pediatric obesity. More research is needed to understand intergenerational transmission of obesity. A large focus has been on epigenetic modification. Endothelial dysfunction and inflammation may play important roles in these pathways. Effective biomarkers, including endocan, may also serve as intermediate outcomes in future pregnancy research.

Abstract
BACKGROUND The 'WHO-ASPHER Roadmap to Professionalizing the Public Health Workforce in the European Region' provides recommendations for strategic and systematic workforce planning around professionalization levers including: (i) competencies, (ii) training and education, (iii) formal organization, (iv) professional credentialing and (v) code of ethics and professional conduct as well as taxonomy and enumeration. It was based on a literature review till 2016. This scoping review aims to explore how the professionalization was documented in the literature between 2016 and 2022. METHODS Following the Joanna Briggs Institute guidelines, we searched Medline via PubMed, Web of Science, ERIC via EBSCO and Google Scholar and included studies on professionalization levers. Four critical appraisal tools were used to assess qualitative, quantitative, mixed methods studies and grey literature. The PRISMA Extension for Scoping Reviews (PRISMA-ScR) was used for reporting. RESULTS Eleven articles included in this review spanned 61 countries, targeting undergraduate, master's, doctoral degrees and continuing professional development. Most of these documents were reviews. About half provided a definition of the public health workforce; more than half covered the taxonomy and included information about competences, but the use of frameworks was sporadic and inconsistent. Formal organization and the necessity of a code of conduct for the public health workforce were acknowledged in only two studies. CONCLUSIONS In spite of some efforts to professionalize the public health workforce, this process is fragmented and not fully recognized and supported. There is an urgent need to engage policymakers and stakeholders to prioritize investments in strengthening the public health workforce worldwide.

Abstract
A concise review is given of astrophysically motivated experimental and theoretical research on Taylor-Couette flow. The flows of interest rotate differentially with the inner cylinder faster than the outer, but are linearly stable against Rayleigh's inviscid centrifugal instability. At shear Reynolds numbers as large as [Formula: see text], hydrodynamic flows of this type (quasi-Keplerian) appear to be nonlinearly stable: no turbulence is seen that cannot be attributed to interaction with the axial boundaries, rather than the radial shear itself. Direct numerical simulations agree, although they cannot yet reach such high Reynolds numbers. This result indicates that accretion-disc turbulence is not purely hydrodynamic in origin, at least insofar as it is driven by radial shear. Theory, however, predicts linear magnetohydrodynamic (MHD) instabilities in astrophysical discs: in particular, the standard magnetorotational instability (SMRI). MHD Taylor-Couette experiments aimed at SMRI are challenged by the low magnetic Prandtl numbers of liquid metals. High fluid Reynolds numbers and careful control of the axial boundaries are required. The quest for laboratory SMRI has been rewarded with the discovery of some interesting inductionless cousins of SMRI, and with the recently reported success in demonstrating SMRI itself using conducting axial boundaries. Some outstanding questions and near-future prospects are discussed, especially in connection with astrophysics. This article is part of the theme issue 'Taylor-Couette and related flows on the centennial of Taylor's seminal Philosophical Transactions paper (Part 2)'.

Abstract
A 33-year-old multiparous term parturient requested an epidural for labour analgesia. An accidental dural puncture was noted at the time of epidural needle insertion and an intrathecal catheter was placed. The intrathecal catheter was removed 10 h later and was noted to be intact. The following day, there was a significant leak of clear fluid from the catheter insertion site. Cerebrospinal fluid was detected using beta-trace protein testing. The patient remained asymptomatic and we deduced the cause could be a cutaneous fistula. Similar published reports have suggested the causes of similar presentations could include leakage of interstitial oedema, local anaesthetic or cerebrospinal fluid. It is important to consider the diagnosis of clear fluid leakage following an accidental dural puncture and the management of a cerebrospinal fluid-cutaneous fistula in the absence of neurological symptoms.

Abstract
Essentials MEDI2452 is a specific antidote of the platelet P2Y12 receptor antagonist ticagrelor. Hemostatic effects of MEDI2452 were evaluated in pigs treated with ticagrelor and aspirin. MEDI2452 eliminated free ticagrelor within 5 min and gradually normalized platelet aggregation. Improvements in blood pressure (significant) and in blood-loss and survival (non-significant) were observed. SUMMARY Background Ticagrelor, a P2Y12 antagonist, is approved for the prevention of thromboembolic events. However, antiplatelet therapies carry a risk of bleeding. Objective To explore the hemostatic effects of MEDI2452, an antidote for ticagrelor. Methods Pigs, pre-treated with aspirin, were given an intravenous infusion of ticagrelor or vehicle. At the end of the infusion, a piece of a liver lobe was cut off and a bolus of MEDI2452 or vehicle was administered intravenously. Blood was collected to monitor blood loss, mean arterial blood pressure (MAP) was recorded and survival time was observed over 4 h. Blood samples for drug plasma exposures and platelet aggregation were collected. Results MEDI2452 eliminated the free concentrations of ticagrelor and its active metabolite AR-C124910XX within 5 min. ADP-induced platelet aggregation was close to normal at 60 min, which was not significantly different from aspirin alone. MEDI2452 numerically reduced ticagrelor-mediated effects: body-weight-adjusted blood loss in the 15- to 90-min interval, 12 (confidence interval [CI] 95% 7-28] vs. 17 (CI 95% 5-31) (ticagrelor and aspirin) vs. 5 (CI 95% 3-9) mL kg-1 (aspirin alone), survival 70% (CI 95% 47-100) vs. 45% (CI 95% 21-92) (ticagrelor and aspirin) vs. 100% (CI 95% 100-100) (aspirin alone), and median survival time, 240 (CI 95% 180-240) vs. 169 (CI 95% 64-240) (ticagrelor and aspirin) vs. 240 (CI 95% 240-240) min (aspirin alone). Finally, MEDI2452 significantly attenuated the decline in MAP, 0.08 (CI 95% 0.07-0.09) vs. 0.141 (CI 95% 0.135-0.148) (ticagrelor and aspirin) vs. 0.04 (CI 95% 0.03-0.05) mmHg per min (aspirin alone) and maintained MAP at a significantly higher level, 73 (CI 95% 51-95) vs. 48 (CI 95% 25-70) (ticagrelor and aspirin) vs. 115 (CI 95% 94-136) mmHg (aspirin alone). Conclusion MEDI2452 eliminated free ticagrelor and AR-C124910XX within 5 min. This translated into a gradual normalization of ADP-induced platelet aggregation and significant improvement in blood pressure and numerical but non-significant improvements in blood-loss and survival.

Abstract
The investigational ticagrelor‐neutralizing antibody fragment, MEDI2452, is developed to rapidly and specifically reverse the antiplatelet effects of ticagrelor. However, the dynamic interaction of ticagrelor, the ticagrelor active metabolite (TAM), and MEDI2452, makes pharmacokinetic (PK) analysis nontrivial and mathematical modeling becomes essential to unravel the complex behavior of this system. We propose a mechanistic PK model, including a special observation model for post‐sampling equilibration, which is validated and refined using mouse in vivo data from four studies of combined ticagrelor‐MEDI2452 treatment. Model predictions of free ticagrelor and TAM plasma concentrations are subsequently used to drive a pharmacodynamic (PD) model that successfully describes platelet aggregation data. Furthermore, the model indicates that MEDI2452‐bound ticagrelor is primarily eliminated together with MEDI2452 in the kidneys, and not recycled to the plasma, thereby providing a possible scenario for the extrapolation to humans. We anticipate the modeling work to improve PK and PD understanding, experimental design, and translational confidence.

Abstract
The endocannabinoid system plays a major role in modulating memory. In the present study, we examined whether cannabinoid agonists influence the consolidation of stimulus-response/habit memory, a form of memory dependent upon the dorsolateral striatum (DLS). In Experiment 1, rats were trained in a cued platform water maze task in which animals were released from different start points and in order to escape had to find a cued platform which was moved to various spatial locations across trials. Immediately following training, rats received an i.p. injection of the cannabinoid receptor agonist WIN 55,212-2 (1 or 3mg/kg) or a vehicle solution. In Experiment 2, rats were trained in a forced-response version of the water plus-maze task in which a consistent body-turn response was reinforced across trials. Immediately following training, rats received an i.p. injection of WIN 55,212-2 (3 mg/kg) or vehicle. In Experiment 3, rats were trained in the cued platform task and after training received bilateral intra-DLS WIN 55,212-2 (100 ng/.5 μL or 200 ng/.5 μL) or vehicle. In Experiments 1-3, the higher doses of WIN 55,212-2 were associated with significant memory impairments, relative to vehicle-treated controls. The results indicate that peripheral or intra-DLS administration of a cannabinoid receptor agonist impairs consolidation of DLS-dependent memory. The findings are discussed within the context of previous research encompassing cannabinoids and DLS-dependent learning and memory processes, and the possibility that cannabinoids may be used to treat some habit-like human psychopathologies (e.g. posttraumatic stress disorder) is considered.

Abstract
Public health has been an enormously effective instrument for improving life expectancy and quality of life. Historically a sphere of governmental activity led by physicians and staffed by sanitarians and nurses, public health has evolved to become a multi-facetted field of societal activity. It engages many agencies and community action in reducing infectious and non-communicable diseases as well as many aspects of lifestyle and health equity. Education for an adequate professional workforce is one of its key functions. Schools of public health have fulfilled this role only partly even in developed countries, but in countries in transition and in low-income countries the problem is much more acute. We discuss the role of mentoring of new schools calling for strong public and private donor support for this as a key issue in global health.

Abstract
BACKGROUND The argument that women in stressful environments spontaneously abort their least fit fetuses enjoys wide dissemination despite the fact that several of its most intuitive predictions remain untested. The literature includes no tests, for example, of the hypothesis that these mechanisms select against small for gestational age (SGA) males. METHODS We apply time-series modeling to 4.9 million California male term births to test the hypothesis that the rate of SGA infants in 1096 weekly birth cohorts varies inversely with labor market contraction, a known stressor of contemporary populations. RESULTS We find support for the hypothesis that small size becomes less frequent among term male infants when the labor market contracts. CONCLUSIONS Our findings contribute to the evidence supporting selection in utero. They also suggest that research into the association between maternal stress and adverse birth outcomes should acknowledge the possibility that fetal loss may affect findings and their interpretation. Strengths of our analyses include the large number and size of our birth cohorts and our control for autocorrelation. Weaknesses include that we, like nearly all researchers in the field, have no direct measure of fetal loss.

Abstract
The first observation of fast and slow magnetocoriolis (MC) waves in a laboratory experiment is reported. Rotating nonaxisymmetric modes arising from a magnetized turbulent Taylor-Couette flow of liquid metal are identified as the fast and slow MC waves by the dependence of the rotation frequency on the applied field strength. The observed slow MC wave is damped but the observation provides a means for predicting the onset of the magnetorotational instability.

Abstract
Twelve women with obstetric cholestasis were given dexamethasone after failure to respond to ursodeoxycholic acid. Clinical improvement was achieved in eight cases, without complete resolution of symptoms. Biochemical response was achieved in seven cases. All but two cases had good correlation between clinical and biochemical response. Women of Asian and South American origin were more likely to respond to dexamethasone than Caucasians. There were no reported maternal or fetal side-effects. However, the subsequent consequences of dexamethasone treatment for the mother and fetus have not been thoroughly evaluated. Therefore, even in Asian and South American women, larger studies of dexamethasone are required before this treatment can be recommended as a universally safe and effective treatment for obstetric cholestasis.

Abstract
Vitamin B12 deficiency may be an independent risk factor for neural tube defects (NTD). We determined the prevalence of biochemical B12 deficiency (<125 pmol/l) among 10 622 Ontarian women aged 15-46 years who underwent concomitant testing of serum bhCG and B12 9 years after the implementation of Canadian folic acid flour fortification. The overall prevalence of biochemical B12 deficiency was 7.4%. Relative to non-pregnant women, the adjusted odds ratio (95% confidence interval) of biochemical B12 deficiency was 0.78 (0.60-1.0) among women pregnant 28 days gestation or less and was 1.4 (1.1-1.8) after 28 days gestation. About 1 in 20 women may be deficient in B12 in early pregnancy. The impact on maternal and fetal well-being, including preventable NTD, should be considered.

Abstract
BACKGROUND The introduction of the RP6 (InTouch Health, Santa Barbara, CA, USA) remote-presence "robot" appears to offer a useful telemedicine device. The authors describe the deployment and early experience with the RP6 in a community hospital and provided a live demonstration of the system on April 16, 2005 during the Emerging Technologies Session of the 2005 SAGES Meeting in Fort Lauderdale, Florida. METHODS The RP6 is a 5-ft 4-in. tall, 215-pound robot that can be remotely controlled from an appropriately configured computer located anywhere on the Internet (i.e., on this planet). The system is composed of a control station (a computer at the central station), a mechanical robot, a wireless network (at the remote facility: the hospital), and a high-speed Internet connection at both the remote (hospital) and central locations. The robot itself houses a rechargeable power supply. Its hardware and software allows communication over the Internet with the central station, interpretation of commands from the central station, and conversion of the commands into mechanical and nonmechanical actions at the remote location, which are communicated back to the central station over the Internet. The RP6 system allows the central party (e.g., physician) to control the movements of the robot itself, see and hear at the remote location (hospital), and be seen and heard at the remote location (hospital) while not physically there. RESULTS Deployment of the RP6 system at the hospital was accomplished in less than a day. The wireless network at the institution was already in place. The control station setup time ranged from 1 to 4 h and was dependent primarily on the quality of the Internet connection (bandwidth) at the remote locations. Patients who visited with the RP6 on their discharge day could be discharged more than 4 h earlier than with conventional visits, thereby freeing up hospital beds on a busy med-surg floor. Patient visits during "off hours" (nights and weekends) were three times more efficient than conventional visits during these times (20 min per visit vs 40-min round trip travel + 20-min visit). Patients and nursing personnel both expressed tremendous satisfaction with the remote-presence interaction. CONCLUSIONS The authors' early experience suggests a significant benefit to patients, hospitals, and physicians with the use of RP6. The implications for future development are enormous.

Abstract
The Interagency Steering Committee on Radiation Standards (ISCORS) has recently completed a study of the occurrence within the United States of radioactive materials in sewage sludge and sewage incineration ash. One component of that effort was an examination of the possible transport of radioactivity from sludge into the local environment and the subsequent exposure of humans. A stochastic environmental pathway model was applied separately to seven hypothetical, generic sludge-release scenarios, leading to the creation of seven tables of Dose-to-Source Ratios (DSR), which can be used in translating from specific activity in sludge into dose to an individual. These DSR values were then combined with the results of an ISCORS survey of sludge and ash at more than 300 publicly owned treatment works, to explore the potential for radiation exposure of sludge workers and members of the public. This paper provides a brief overview of the pathway modeling methodology employed in the exposure and dose assessments and discusses technical aspects of the results obtained.

Abstract
This study examined what is communicated by facial expressions of anger and mapped the neural substrates, evaluating the motivational salience of these stimuli. During functional magnetic resonance imaging, angry and neutral faces were presented to human subjects. Across experimental runs, signal adaptation was observed. Whereas fearful faces have reproducibly evoked response habituation in amygdala and prefrontal cortex, angry faces evoked sensitization in the insula, cingulate, thalamus, basal ganglia, and hippocampus. Complementary offline rating and keypress experiments determined an aversive rank ordering of angry, fearful, neutral, and happy faces and revealed behavioral sensitization to the angry faces. Subjects rated angry faces, in contrast to other face categories such as fear, as significantly more likely to directly inflict harm. Furthermore, they rated angry faces as significantly less likely to produce positive emotional outcomes than the other face categories. Together these data argue that angry faces, a directly aversive stimulus, produce a sensitization response.

Abstract
The Nuclear Regulatory Commission (NRC) announced the availability of three new documents concerning radioactive materials in sewage sludge and ash from publicly owned treatment works (POTW). One of the documents is a report presenting the results of a volunteer survey of sewage sludge and ash samples provided by 313 POTWs. The second document is a dose modeling document, using multiple exposure pathway modeling focused on a series of generic scenarios, to track possible exposure of POTW workers and members of the general public to radioactivity from the sewage sludge or ash. The third document is a guidance report providing recommendations on the management of radioactivity in sewage sludge and ash for POTW owners and operators. This paper explains how radioactive materials enter POTWs, provides criteria for evaluating levels of radioactive material in sludge and ash, and gives a summary of the results of the survey and dose modeling efforts.

Abstract
Physiologic autoantibodies are part of our normal immune repertoire where they function to maintain homeostasis by performing physiologic functions. The role of physiologic autoantibodies in removing senescent and damaged cells is probably the best example of a physiologic autoantibody, complete with well established function. IgG autoantibodies bind to altered band 3 anion exchanger protein on senescent cells and trigger their removal by macrophages. Band 3 isoforms are found in all cells, tissues, and membranes, and in all species examined. In this paper, we discuss the innate immune response to band 3 membrane proteins and their regulation of cellular lifespan. The role of physiologic autoantibodies and their peptide antigens in health and disease, apoptosis, and their therapeutic potential is discussed focusing on the examples of senescence and malaria.

Abstract
OBJECTIVE An understanding of how verbal and non verbal language develops and how it is related to social behavior is essential in order to devise effective interventions for children with disorders of communication. We review the literature on interventions for children with communication disorders from the perspective of the clinical neurologist emphasizing both therapeutic and pharmacological interventions. FINDINGS Our knowledge on effective interventions in children with disorders of communications is limited due to the heterogeneity of the population and the lack of well controlled studies. There is some limited data suggesting that therapeutic interventions for children with language impairments are most effective if all forms of communication are emphasized. Interventions should be adapted to the age of presentation and associated clinical findings of the child. CONCLUSIONS A multimodal intervention approach is essential to maximize the potential of children with communication disorders. The role of medication in interventions for children with disorders of communication is limited to the treatment of associated symptoms that may interfere with the ability of a child to receive non pharmacological therapeutic interventions.

Abstract
Nonphysiological sensing by a pacing and defibrillation electrode may result in inappropriate defibrillator discharges and/or inhibition of pacing. Active-fixation electrodes may be more likely to sense diaphragmatic myopotentials because of the protrusion of the screw for fixation. In addition, the movement of the fixation screw in an integrated bipolar lead system could also result in inappropriate sensing. This may be increasingly important in patients who are pacemaker dependent because the dynamic range of the autogain feature of these devices is much more narrow. Five of 15 consecutive patients who received a CPI model 0154 or 0155 active-fixation defibrillation electrode with an ICD system (CPI Ventak A V3DR model 1831 or CPI Ventak VR model 1774 defibrillator) are described. In 2 of the 15 patients, nonphysiological sensing appearing to be diaphragmatic myopotentials resulted in inappropriate defibrillator discharges. Both patients were pacemaker dependent. Changes in the sensitivity from nominal to less sensitive prevented inappropriate discharges. In one patient, discreet nonphysiological sensed events with the electrogram suggestive of ventricular activation was noted at the time of implantation. This was completely eliminated by redeployment of the active-fixation lead in the interventricular septum. In two other patients, discreet nonphysiological sensed events resulted in intermittent inhibition of ventricular pacing after implantation. These were still seen in the least sensitive autogain mode for ventricular amplitude. These were not seen on subsequent interrogation 1 month after implantation. Increased awareness of nonphysiological sensing is recommended. The CPI 0154 and 0155 leads seem to be particularly prone to this abnormality. Particular attention should be made when deploying an active-fixation screw for an integrated bipolar lead. This increased awareness is more important when a given individual is pacemaker dependent, which may warrant DFT testing in a least or less sensitive mode in these patients.

Abstract
Voltage-gated calcium channels (VGCCs) within sensory neurones are believed to perform an important role in neuropathic pain. In the present study we examine the changes in VGCC mRNA which occur following streptozocin- (STZ) induced diabetic neuropathy using in situ hybridization. STZ caused a significant increase in alpha(2)delta(1), alpha(2)delta(2), and alpha(2)delta(3) mRNA levels in all neuronal cell types. Similarly, mRNA levels of alpha(1F), alpha(1I), and alpha(1S) were increased in all cell types studied whilst alpha(1A) and alpha(1G) mRNAs were specifically upregulated in medium and large diameter neurones. In conclusion, we demonstrate that the induction of diabetic neuropathy is associated with dramatic changes in the expression of VGCCs.
