Abstract
PURPOSE Newborn removal by North America's child protective services (CPS) disproportionately impacts Indigenous and Black families, yet its implications for population health inequities are not well understood. To guide this as a domain for future research, we measured validity of birth hospitalization discharge codes categorizing newborns discharged to CPS. METHODS Using data from 309,260 births in Manitoba, Canada, we compared data on newborns discharged to CPS from hospital discharge codes with the presumed gold standard of custody status from CPS case reports in overall population and separately by First Nations status (categorization used in Canada for Indigenous peoples who are members of a First Nation). RESULTS Of 309,260 newborns, 4562 (1.48%) were in CPS custody at hospital discharge according to CPS case reports and 2678 (0.87%) were coded by hospitals as discharged to CPS. Sensitivity of discharge codes was low (47.8%), however codes were highly specific (99.8%) with a positive predictive value (PPV) of 81.4%, and a negative predictive value (NPV) of 99.2%. Sensitivity, PPV and specificity were equal for all newborns but NPV was lower for First Nations newborns. CONCLUSIONS Canadian hospital discharge records underestimate newborn discharge to CPS, with no difference in misclassication based on First Nations status.

Abstract
Basal ganglia and thalamus (BGT) hypoxic-ischaemic brain injury is currently the most contentious issue in cerebral palsy (CP) litigation in South Africa (SA), and merits a consensus response based on the current available international literature. BGT pattern injury is strongly associated with a preceding perinatal sentinel event (PSE), which has a sudden onset and is typically unforeseen and unpreventable. Antepartum pathologies may result in fetal priming, leading to vulnerability to BGT injury by relatively mild hypoxic insults. BGT injury may uncommonly follow a gradual-onset fetal heart rate deterioration pattern, of duration ≥1 hour. To prevent BGT injury in a clinical setting, the interval from onset of PSE to delivery must be short, as little as 10 - 20 minutes. This is difficult to achieve in any circumstances in SA. Each case needs holistic, multidisciplinary, unbiased review of all available antepartum, intrapartum and postpartum and childhood information, aiming at fair resolution without waste of time and resources.

Abstract
Mice reconstituted with human immune systems are instrumental in the investigation of HIV-1 pathogenesis and therapeutics. Natural killer (NK) cells have long been recognized as a key mediator of innate anti-HIV responses. However, established humanized mouse models do not support robust human NK cell development from engrafted human hematopoietic stem cells (HSCs). A major obstacle to human NK cell reconstitution is the lack of human interleukin-15 (IL-15) signaling, as murine IL-15 is a poor stimulator of the human IL-15 receptor. Here, we demonstrate that immunodeficient NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice expressing a transgene encoding human IL-15 (NSG-Tg(IL-15)) have physiological levels of human IL-15 and support long-term engraftment of human NK cells when transplanted with human umbilical-cord-blood-derived HSCs. These Hu-NSG-Tg(IL-15) mice demonstrate robust and long-term reconstitution with human immune cells, but do not develop graft-versus-host disease (GVHD), allowing for long-term studies of human NK cells. Finally, we show that these HSC engrafted mice can sustain HIV-1 infection, resulting in human NK cell responses in HIV-infected mice. We conclude that Hu-NSG-Tg(IL-15) mice are a robust novel model to study NK cell responses to HIV-1.

Abstract
BACKGROUND Reconstructive surgery is established as a standard treatment option after mastectomy due to cancer. It is crucial to patients to achieve a natural and symmetric looking breast through reconstruction. Anthropometric measurements are used to assess the objective symmetry of the breast, which are prone to errors and difficult to reproduce. OBJECTIVE The aim of this work is to validate breast volumetry using three-dimensional surface imaging. METHODS We compared preoperatively analog and digitally evaluated volume of the breast with our gold standard, direct water displacement measurement of the mastectomy specimen. We examined 34 breast specimens in total. RESULTS Each measurement method (Breast Sculptor, VAM, Breast-V) for breast volume/mass determination demonstrates acceptable agreement ranges when compared with resected volumes and masses. The strongest volumetry instrument is Breast Sculptor (digital), the weakest is Breast-V (analog). CONCLUSIONS 3D surface imaging is a quick, effective, and convenient method to evaluate breast shape and volume. The accuracy, reproducibility, and reliability of 3D surface imaging were comparable with MRI in our study.This takes us a step closer to the long-term goal of establishing robust instruments to plan breast reconstructive surgery, achieve better surgical results, and contribute to quality assurance in breast surgery.

Abstract
Alcohol use disorder (AUD) is a chronic relapsing disorder characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD is associated with a variety of physiological changes and is a substantial risk factor for numerous diseases. We aimed to characterize systemic alterations in immune responses using a well-established mouse model of chronic intermittent alcohol exposure to induce alcohol dependence. We exposed mice to chronic intermittent ethanol vapor for 4 weeks and analyzed the expression of cytokines IFN-γ, IL-4, IL-10, IL-12 and IL-17 by different immune cells in the blood, spleen and liver of alcohol dependent and non-dependent control mice through multiparametric flow cytometry. We found increases in IFN-γ and IL-17 expression in a cell type- and organ-specific manner. Often, B cells and neutrophils were primary contributors to increased IFN-γ and IL-17 levels while other cell types played a secondary role. We conclude that chronic alcohol exposure promotes systemic pro-inflammatory IFN-γ and IL-17 responses in mice. These responses are likely important in the development of alcohol-related diseases, but further characterization is necessary to understand the initiation and effects of systemic inflammatory responses to chronic alcohol exposure.

Abstract
Influenza viruses have perplexed scientists for over a hundred years. Yearly vaccines limit their spread, but they do not prevent all infections. Therapeutic treatments for those experiencing severe infection are limited; further advances are held back by insufficient understanding of the fundamental immune mechanisms responsible for immunopathology. NK cells and T cells are essential in host responses to influenza infection. They produce immunomodulatory cytokines and mediate the cytotoxic response to infection. An imbalance in NK and T cell responses can lead to two outcomes: excessive inflammation and tissue damage or insufficient anti-viral functions and uncontrolled infection. The main cause of death in influenza patients is the former, mediated by hyperinflammatory responses termed “cytokine storm.” NK cells and T cells contribute to cytokine storm, but they are also required for viral clearance. Many studies have attempted to distinguish protective and pathogenic components of the NK cell and T cell influenza response, but it has become clear that they are dynamic and integrated processes. This review will analyze how NK cell and T cell effector functions during influenza infection affect the host response and correlate with morbidity and mortality outcomes.

Abstract
Background Orthodontic treatment of newborns and infants with Robin-Sequence using the Tübingen Palatal Plate (TPP) is a complex procedure that could benefit from simplification through digitalization. The design of the velar extension (spur) and the palatal base determines the success of the treatment. Therefore, a prototype must be produced and inserted under endoscopic supervision in order to determine the appropriate shape, length and position of the spur. This technical note demonstrates a fully digital workflow for the design and manufacturing of a functional TPP prototype, based on an intraoral scan. This prototype can be altered and individualized digitally for each patient. After the shape and position of the spur have been optimized, the prototype is duplicated using a silicone mold. Then the definitive TPP is manufactured and inserted. We aim to present a workflow which facilitates the fitting procedure and does not require a conventional impression or a physical model to create the appliance. Methods As described in part I of this series, the intraoral scan is performed using the 3Shape TRIOS3 scanner and its corresponding acquisition software. The virtual model is rendered in the 3Shape ortho appliance designer and the base of the palatal plate is designed in the 3Shape dental designer. The palatal plate and the virtual model are then imported into Autodesk Meshmixer and a standardized spur is positioned and merged with the base. The TPP is exported in Standard Tessellation Language (STL) format and manufactured on a W2P Solflex 170 DLP printer using VOCO VPrint Splint material (MDR Class IIa). Results Based on an intraoral scan, the TPP prototype could be successfully manufactured and proved suitable for the patients’ treatment. Conclusion The new digital workflow for the design of the TPP can been successfully implemented into daily clinical routine in our facility. Patients could be alleviated from having to undergo conventional impression procedures and fitting of the TPP could be facilitated by producing multiple functional prototypes for endoscopic evaluation. Through rapid prototyping, the expenditure of the fitting process was reduced, which makes the TPP therapy more efficient and accessible to a wider range of clinicians.

Abstract
Background Advanced digital workflows in orthodontics and dentistry often require a combination of different software solutions to create patient appliances, which may be a complex and time-consuming process. The main objective of this technical note is to discuss treatment of craniofacial anomalies using digital technologies. We present a fully digital, linear workflow for manufacturing palatal plates for infants with craniofacial anomalies based on intraoral scanning. Switching to intraoral scanning in infant care is advantageous as taking conventional impressions carries the risk of impression material aspiration and/or infections caused by material remaining in the oronasal cavity. Material and methods The fully digital linear workflow presented in this technical note can be used to design and manufacture palatal plates for cleft palate patients as well as infants with functional disorders. We describe the workflow implemented in an infant with trisomy 21. The maxilla was registered using a digital scanner and a stimulation plate was created using dental CAD software and an individual impression tray module on a virtual model. Plates were manufactured using both additive and subtractive methods. Methacrylate based light curing resin and Poly-Ether-Ether-Ketone were the materials used. Results The palatal area was successfully scanned to create a virtual model. The plates fitted well onto the palatal area. Manual post-processing was necessary to optimize a functional ridge along the vestibular fold and remove support structures from the additively manufactured plate as well as the milled plate produced from a blank. The additively manufactured plate fitted better than the milled one. Conclusion Implementing a fully digital linear workflow into clinical routine for treatment of neonates and infants with craniofacial disorders is feasible. The software solution presented here is suitable for this purpose and does not require additional software for the design. This is the key advantage of this workflow, which makes digital treatment accessible to all clinicians who want to deal with digital technology. Whether additive or subtractive manufacturing is preferred depends on the appliance material of choice and influences the fit of the appliance.

Abstract
OBJECTIVE The purpose of this study was to evaluate the success rate and complications of medical termination of pregnancy up to 49 days of amenorrhea and present the outcome of our phone questionaire of satisfaction of patients. DESIGN Retrospective analysis. SETTING Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno. METHODS The analysis of 111 patients, who underwent medical termination of pregnancy at the Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno from 1. 6. 2014 to 30. 6. 2015 using 600 mg of mifepristone (Mifegyne) and 400 µg of misoprostol (Mispregnol). In our set of patients we monitored subjective perception of medical termination of pregnancy (pain, nausea, vomiting, satisfaction with this method) and objective process (hospitalisation, surgical intervention). The view of patients was found out by the phone questionnaire RESULTS Complete abortion without a surgical intervention underwent 103 patients. Nausea, pelvic pain, and intensity of bleeding were evaluated as suitable. Only 1 patient (0.9%) was hospitalised for nausea and 1 patient (0.9%) was hospitalised in case of need for an emergency curretage and transfusions. Some kind of contraception after the medical termination of pregnancy started using 98.0% of women. The satisfaction rate of this method was high - 101 patients declared themselves satisfied - 66.7% very satisfied, 24.3% rather satisfied. CONCLUSION Medical termination of pregnancy has good efficiency, we consider it safe with minimum side-effects and is well evaluated by patients.

Abstract
Management strategies in rotational grazing systems differ in their level of complexity and adaptivity. Different components of such grazing strategies are expected to allow for adaptation to environmental heterogeneities in space and time. However, most models investigating general principles of rangeland management strategies neglect spatio-temporal system properties including seasonality and spatial heterogeneity of environmental variables. We developed an ecological-economic rangeland model that combines a spatially explicit farm structure with intra-annual time steps. This allows investigating different management components in rotational grazing systems (including stocking and rotation rules) and evaluating their effect on the ecological and economic states of semi-arid grazing systems. Our results show that adaptive stocking is less sensitive to overstocking compared to a constant stocking strategy. Furthermore, the rotation rule becomes important only at stocking numbers that maximize expected income. Altogether, the best of the tested strategies is adaptive stocking combined with a rotation that adapts to both spatial forage availability and seasonality. This management strategy maximises mean income and at the same time maintains the rangeland in a viable condition. However, we could also show that inappropriate adaptation that neglects seasonality even leads to deterioration. Rangelands characterised by higher inter-annual climate variability show a higher risk of income losses under a non-adaptive stocking rule, and non-adaptive rotation is least able to buffer increasing climate variability. Overall, all important system properties including seasonality and spatial heterogeneity of available resources need to be considered when designing an appropriate rangeland management system. Resulting adaptive rotational grazing strategies can be valuable for improving management and mitigating income risks.

Abstract
BACKGROUND Developmental milestone markers for fine motor and self-care skills among children with Down syndrome (DS) are either minimal, anecdotal or out-of date. Our goal was to produce normative expectations for the development of fine motor and self-care milestones specific to children with DS. METHOD A cross-sectional retrospective chart review was completed on 274 children with DS seen at a specialty clinic that ranged in age from 4 months to 18 years. Specific skills were assessed at occupational therapy assessments as either present or absent, including fine motor, handwriting, scissor usage, self-feeding and clothing management. RESULTS Fine motor milestones describing when 10-30% ('early achievers') and 75-95% ('representative achievement') of children with DS had mastered each skill were developed based upon descriptive review. As the fine motor and self-care skills advanced in complexity, the range of ages for documented skill acquisition was observed to increase. CONCLUSIONS Age ranges for the mastery of fine motor developmental milestones for early and representative achievement were developed based upon descriptive analysis of cross-sectional retrospective clinical chart reviews. That the age range for mastering fine motor and self-care skills broadens as children with DS get older is in agreement with what is identified in the DS behavioural phenotype with regard to variable motor skills overall. These fine motor and self-care developmental milestone markers contribute to the field by informing parents, caregivers and healthcare providers of potential fine motor and self-care outcomes and describing normative development for children with DS.

Abstract
OBJECTIVE Tracheotomized patients often suffer from impairments in mucociliary clearance and limited capacities for active expectoration of secretions. We investigated the effects of a specific respiratory intervention method (bagging) for tracheotomized patients on respiratory parameters (pO2, pCO2, SpO2, respiratory rates), swallowing frequency, vigilance and secretion viscosity. METHODS The bagging method supports enforced mobilization and expectoration of secretions by application of a series of manual hyperinflations with a resuscitation bag during active inspiration and manual cough support on the chest. 30 tracheotomized neurological patients participated in a multiple-baseline study including a three-weeks intervention period and a follow-up measurement three weeks after termination of the treatment. RESULTS Most outcome parameters improved significantly during the intervention period: pO2 (p < .01), SpO2 (p < .01), respiratory rates (p < .01), swallowing rates (p < .01), and vigilance scores (p < .01). The quality of bronchial secretions improved in all participants. All effects were sustained up to the follow-up measurements. CONCLUSION This preliminary data indicates positive effects for a respiratory intervention method (bagging) on respiratory function and additional respiration-related functions in tracheotomized neurological patients. This easy-to-learn and inexpensive method might expand the range of treatment options for tracheotomized and non-responsive patients.

Abstract
BACKGROUND Epidemiological findings suggest that the link between poverty and pre-eclampsia might be dietary calcium deficiency. Calcium supplementation has been associated with a modest reduction in pre-eclampsia, and also in blood pressure (BP). METHODS This exploratory sub-study of the WHO Calcium and Pre-eclampsia (CAP) trial aims to determine the effect of 500mg/day elemental calcium on the blood pressure of non-pregnant women with previous pre-eclampsia. Non-pregnant women with at least one subsequent follow-up trial visit at approximately 12 or 24weeks after randomization were included. RESULTS Of 836 women randomized by 9 September 2014, 1st visit data were available in 367 women of whom 217 had previously had severe pre-eclampsia, 2nd visit data were available in 201 women. There was an overall trend to reduced BP in the calcium supplementation group (1-2.5mmHg) although differences were small and not statistically significant. In the subgroup with previous severe pre-eclampsia, the mean diastolic BP change in the calcium group (-2.6mmHg) was statistically larger than in the placebo group (+0.8mmHg), (mean difference -3.4, 95% CI -0.4 to -6.4; p=0.025). The effect of calcium on diastolic BP at 12weeks was greater than in those with non-severe pre-eclampsia (p=0.020, ANOVA analysis). CONCLUSIONS There is an overall trend to reduced BP but only statistically significant in the diastolic BP of women with previous severe pre-eclampsia. This is consistent with our hypothesis that this group is more sensitive to calcium supplementation, however results need to be interpreted with caution.

Abstract
Hyponatremia is one of the most common metabolic disorders in clinical medicine. The value of Na+ in serum equalling 135 mmol/ l and lower is regarded as hyponatremia. Its clinical manifestations are the following: headaches, nausea, vomiting, seizures, numbness, coma and death. Hyponatremia caused by nonosmotic hypersecretion of vasopressin can be divided into: a) hypovolemic, b) normovolemic and c) hypervolemic. Hyponatremia which is not caused by the hypersecretion of vasopressin is the so called pseudohyponatremia, water intoxication, cerebral salt loss syndrome. Hypovolemic hyponatremia is caused by the loss of Na+ and fluid loss from the organism. It occurs, for example, after using thiazide diuretics, after recurrent diarrhoea, vomiting, after significant blood loss and other causes. Treatment of this disorder must focus on the producing cause and on the parenteral administration of 0.9% NaCl. Normovolemic hyponatremia can be with or without symptoms. Acute normovolemic hyponatremia is treated by the intravenous administration of 3% NaCl and with the simultaneous use of loop diuretics (20- 40 mg Furosemide/ 24 hrs) and restriction of fluid intake. In the case of chronic normovolemic hyponatremia, refractory to the previous treatment, caused by the inappropriate secretion of arginine vasopressin, it is recommended to use perorally its V2- receptor blocker, Tolvaptan. Hypervolemic hyponatremia occurs in the case of cardiovascular failure, with hepatic cirrhosis, nephrotic syndrome, renal failure, porphyric disease and other conditions. Symptoms occurring with it are swellings, ascites, distension of jugular veins and the presence of unaccented rales in the lungs, which can be detected during physical examination. For treatment it is recommended to restrict fluid intake and to administer NaCl as well as diuretic therapy. Recently it has been recommended to use Tolvaptan which increases excretion of free water (aquaresis), decreases osmolality in the urine, and leads to the increase in serum Na+. Apart from that, we present our three clinical laboratory observations in the paper: 1. Contrary to the data in the literature, after the Košice Marathon (42.125 km) the serum concentration of Na+ in the runners increased (from 144.4 ± 2.1 mmol/ l to 147 ± 2.8 mmol/ l, p < 0.01) in spite of a significant reduction in the body weight (from 73.2 ± 5.7 kg to 71.9 ± 5.2 kg, p < 0.05), intensive perspiration and dehydration (blood haemoglobin before the run: 150.4 ± 5.5 g/ l, after the run: 152.1 ± 4.8 g/ l, p < 0.05). Apart from that, we detected a significant decrease in the fractional excretion of sodium (FENa) from 1.16 ± 0.30% to 0.34 ± 0.10%, p < 0.01. 2. One patient with chronic intermittent porphyria displayed the syndrome of inappropriate antidiuretic hormone secretion, which had been positively influenced by the restriction of fluid intake in the long term and by peroral administration of 1- 3 g NaCl/ 24 hrs. 3. In 15 haemodialysed patients with chronic renal failure, who displayed recurrent hypervolemic hyponatremia, we achieved, by means of adequate ultrafiltration and a dialysis solution containing Na+ 145 mmol/ l, the serum concentration of Na+ 142 mmol/ l at the end of haemodialysis.

Abstract
In a pilot project we examined whether an improvement of oxygen saturation (SPO (2)) can be established by applying a modified respiratory intervention technique (bagging) for patients in early neurorehabilitation. The "bagging" method involves adding air into the lungs during the inspiration phase by using a resuscitation bag. Subsequently, the patient is requested to cough, and is given manual support on the chest by the therapist. We examined a group of 11 patients who received 1 - 2 bagging interventions per day over a period of 12 days. By applying the bagging method, a continuous and stable improvement of oxygen saturation could be accomplished for all patients. A single case analysis confirmed this effect for each patient. Furthermore, we observed an improvement of the patients' vigilance, improved quality of bronchial secretion and marked improvements in swallowing and phonation. The bagging method is an easy-to-learn and inexpensive method that leads to a stable and sustained increase in oxygen saturation and to improvement of other clinical parameters.
